Outcomes of symptomatic gallstone disease in pregnant women: A retrospective study

Gallstone disease with advanced symptoms is one of the common abdominal emergencies during pregnancy and it is considered to be one of the most frequently reported non-obstetric surgical conditions in pregnant women. This study aimed to evaluate the outcomes of surgical cholecystectomy in pregnant women with symptoms of advanced gallstones. This is a retrospective analysis of 2814 pregnant women who attended various wards in government and private hospitals in the governorates of Diyala and Kirkuk in Iraq for more than 2 years, between February 2020 and June 2022. The hospital database was used to confirm the diagnosis of advanced gallstone symptoms in these pregnant women. The incidence of symptomatic gallstones in pregnant women, diagnosis and method of therapeutic management, cholecystectomy according to the pregnancy periods, and perinatal complications of patients according to therapeutic methods were determined. The results confirmed that out of 2814 pregnancies, only 126 (4%) had symptoms of gallstones. It was found that the majority of cases 67 (53%) were within the first trimester of pregnancy and the least 29 (23%) was observed in the second trimester. Acute cholecystitis was the generality 84 (67%) diagnosed in pregnant women with symptomatic gallbladder disease and only 9 (7%) of the patients had undergone prenatal cholecystectomy versus 117 (93%) who were managed conservatively. A total of 20 (16%) cases with undesirable complications were recorded, where 12 cases with low birth weight were noted, where 4 of them underwent surgery and 8 were treated conservatively. It was concluded that a large proportion of women suffer from symptoms of gallstones during pregnancy. Most cases can be managed conservatively, and intervention should be performed as often as needed.Copyright © 2023, Codon Publications. All rights reserved.

Comparison of Comorbidities between Adults and Children with Glycogen Storage Disease Type Ia (GSDIA)

Objectives: Glycogen Storage Disease Type Ia (GSDIa) is a rare inherited disorder resulting in acute hypoglycemia due to impaired release of glucose from glycogen. Despite dietary management practices to prevent hypoglycemia in patients with GSDIa, complications still occur in children and throughout adulthood. This retrospective cohort study compared the prevalence of complications in adults and children with GSDIa. Method(s): Using ICD-10 diagnosis codes, the IQVIA Pharmetrics Plus database was searched for patients with >=2 GSDI claims (E74.01) from January 2016 through February 2020, with >=12 months continuous enrollment beginning prior to March 2019 (for one year of follow-up before COVID-19), and no inflammatory bowel disease diagnoses (indicative of GSDIb). Complication prevalence in adults and children with GSDIa was summarized descriptively. Result(s): In total, 557 patients with GSDIa were identified (adults, 67%;male, 63%), including 372 adults (median age, 41 years) and 185 children (median age, 7 years). Complications occurring only in adults were atherosclerotic heart disease (8.6%), pulmonary hypertension (3.0%), primary liver cancer (1.9%), dialysis (0.8%), and focal segmental glomerulosclerosis (0.3%). Other complications with the greatest prevalence in adults/children included gout (11.8%/0.5%), insomnia (10.0%/1.1%), osteoarthritis (22.0%/2.7%), severe chronic kidney disease (4.3%/0.5%), malignant neoplasm (10.8%/1.6%), hypertension (49.7%/8.7%), acute kidney failure (15.3%/2.7%), pancreatitis (3.0%/0.5%), gallstones (7.8%/1.6%), benign neoplasm (37.4%/8.1%), hepatocellular adenoma (7.0%/1.6%), neoplasm (41.1%/9.7%), and hyperlipidemia (45.2%/10.8%). Complications with the greatest prevalence in children/adults included poor growth (22.2%/1.9%), gastrostomy (29.7%/3.2%), kidney hypertrophy (2.7%/0.8%), seizure (1.6%/0.5%), hypoglycemia (27.0%/11.3%), hepatomegaly (28.7%/15.9%), kidney transplant (1.6%/1.1%), diarrhea (26.5%/18.6%), nausea and/or vomiting (43.8%/35.8%), acidosis (20.0%/17.2%), and anemia due to enzyme disorders (43.8%/40.6%). Conclusion(s): GSDIa is associated with numerous, potentially serious complications. Compared with children, adults with GSDIa had a greater prevalence of chronic complications, potentially indicating the progressive nature of disease. Children with GSDIa had more acute complications related to suboptimal metabolic control.Copyright © 2023

A Rare Case of Congenital Choledochal Cyst (CCC) Resulting in Recurrent Acute Pancreatitis in an Otherwise Healthy Young Woman

Introduction: Congenital choledochal cyst (CCC) is a rare cystic dilatation of intrahepatic or extrahepatic biliary ducts. We present a case of a type IVb choledochal cyst presenting as recurrent acute pancreatitis in a young healthy female with initial negative screenings. Case Description/Methods: An 18-year-old-female with a history of COVID-19 presented to the emergency department with one month of persistent abdominal pain, nausea, and vomiting. She was hospitalized once prior for similar symptoms and was diagnosed with acute pancreatitis. This admission, blood work showed elevated lipase, elevated liver enzymes, mild bilirubinemia with a normal lipid panel and urine was significant for infection. She received fluids, antiemetics and was started on prophylactic antibiotics for ascending cholangitis. A right upper quadrant ultrasound ruled out cholelithiasis or acute cholecystitis, but showed dilation of the common bile duct. MRCP confirmed dilation with bulbous termination in the periampullary region diagnosed as type IVb choledochal cyst. Discussion(s): CCCs are rare in Western countries with an incidence between 1 in 100,000 to 150,000. 80% of these cysts are diagnosed in patients under the age of 10. They are difficult to diagnose due to variable clinical presentations. A study of 214 CCC patients demonstrated the most common symptom was abdominal pain, followed by jaundice and fever. When cysts are found in adults, symptoms resemble atypical acute biliary tract disease. Surgical cyst removal may be needed for patients with significant risk factors such as older age and age of symptom onset, due to increased risk of malignant transformation. Longer periods of observation have been documented to be associated with an increased chance of developing late complications, such as anastomotic stricture, biliary calculi and recurrent cholangitis. Type IVb CCCs, as seen in this case, consist of multiple extrahepatic cysts and hepaticojejunostomy is the treatment. This patient's young age and recurrent acute pancreatitis combined with her lab and imaging findings strongly suggest the diagnosis of CCC. The anatomical location of the CCC impeded flow of pancreatic enzymes through the ampulla of vater, leading to recurrent pancreatitis in an otherwise healthy young female. CCC, although very rare, should be considered in the differential of acute pancreatitis when other causes such as gallstones and heavy alcohol consumption cannot be identified, as prompt diagnosis and surgical removal is imperative.

Syphilis: "The Great Imitator" Presenting as Acute Hepatitis

Introduction: Syphilis is a multi-systemic disease caused by spirochete Treponema pallidum. Very rarely, it can affect the liver and cause hepatitis. Since most cases of hepatitis are caused by viral illnesses, syphilitic hepatitis can be missed. Here, we present a case of syphilitic hepatitis in a 35-year-old male. Case Description/Methods: Patient was a 35-year-old male who presented to the hospital for jaundice and mild intermittent right upper quadrant abdominal pain. His medical history was only significant for alcohol abuse. His last drink was 4 weeks ago. He was sexually active with men. On exam, hepatomegaly, mild tenderness in the right upper quadrant, jaundice, and fine macular rash on both hands and feet were noted. Lab tests revealed an ALT of 965 U/L, AST of 404 U/L, ALP of 1056 U/L, total bilirubin of 9.5 mg/dL, direct bilirubin of 6.5 mg/dL, INR of 0.96, and albumin of 2.0 g/dL. Right upper quadrant ultrasound showed an enlarged liver but was negative for gallstones and hepatic vein thrombosis. MRI of the abdomen showed periportal edema consistent with hepatitis without any gallstones, masses, or common bile duct dilation. HIV viral load and Hepatitis C viral RNA were undetectable. Hepatitis A & B serologies were indicative of prior immunization. Hepatitis E serology and SARS-CoV-2 PCR were negative. Ferritin level was 177 ng/mL. Alpha-1-antitrypsin levels and ceruloplasmin levels were normal. Anti-Smooth muscle antibody titers were slightly elevated at 1:80 (Normal < 1:20). Anti-Mitochondrial antibody levels were also slightly elevated at 47.9 units (Normal < 25 units). RPR titer was 1:32 and fluorescent treponemal antibody test was reactive which confirmed the diagnosis of syphilis. Liver biopsy was then performed which showed presence of mixed inflammatory cells without any granulomas which is consistent with other cases of syphilitic hepatitis. Immunohistochemical stain was negative for treponemes. Patient was treated with penicillin and did have Jarisch-Herxheimer reaction. ALT, AST, ALP, and total bilirubin down trended after treatment. Repeat tests drawn exactly 1 month post treatment showed normal levels of ALT, AST, ALP, and total bilirubin (Figure). Discussion(s): Liver damage can occur in syphilis and can easily be missed because of the non-specific nature of presenting symptoms. In our patient, the fine macular rash on both hands and feet along with history of sexual activity with men prompted us to test for syphilis which ultimately led to diagnosis and treatment in a timely manner. (Figure Presented).

Nirmatrelvir/ritonavir - A New Culprit of Acute Pancreatitis

Introduction: Nirmatrelvir/ritonavir is a new medication approved for the treatment of COVID-19 infection. It prevents viral replication by inhibiting the SARS-CoV-2 main protease. While mild adverse effects were described, including dysgeusia, diarrhea, hypertension and myalgia1, there were no reported cases of pancreatitis. Case Description/Methods: An 81-year-old female with a past medical history of hypertension and COPD presented to the hospital complaining of abdominal pain and nausea for one day. She had no history of alcohol, tobacco or marijuana use, recent travel, or trauma. Her medications included lisinopril and prednisone, and she had completed a 5-day course of nirmatrelvir/ritonavir for the treatment of COVID-19 infection 2 days prior to presentation. On abdominal exam, she had left upper and lower quadrant tenderness. Blood tests revealed an amylase of 1333 U/L, lipase of 3779 U/L, triglycerides of 297 mg/dL and calcium of 8.7 mg/dL. CT scan revealed an indurated pancreatic body and tail with peripancreatic fluid along the paracolic gutter. Ultrasound of the abdomen and MRCP did not reveal any acute findings. IgG subclasses 1-4 were normal. Discussion(s): According to the revised Atlanta criteria, the patient had clinical findings consistent with acute pancreatitis. Common causes such as gallstone, alcohol, autoimmune and hypertriglyceridemiainduced pancreatitis were ruled out. There were no masses or structural abnormalities on imaging that might have explained her diagnosis. There have been at least 2 reported cases of lisinopril and prednisone induced pancreatitis, however according to Badalov et al.2 both of these medications are class III drugs that lack any rechallenge in the literature. Moreover, the patient had been taking these medications for many years, making them an unlikely cause of the presenting diagnosis. There are no reports of nirmatrelvir/ritonavir associated pancreatitis or known pharmacologic interaction with her home medications, and a meta-analysis conducted by Babajide et al. revealed no association between acute pancreatitis and COVID-19 infection (3). Given the negative findings stated above and the recent initiation of a new medication, nirmatrelvir/ritonavir was the likely cause of acute pancreatitis.

Granulomatous Hepatitis as Primary Manifestation of Disseminated Histoplasmosis in an Immunocompetent Host Diagnosed on EUS FNA and Liver Biopsy

Introduction: Disseminated histoplasmosis (DH) presents as primarily lung manifestations with extrapulmonary involvement in immunocompromised hosts. Granulomatous hepatitis as first presentation of DH in an immunocompetent host is uncommon. Case Description/Methods: 25-year-old female presented with one month of fever, fatigue, myalgias, 30-pound weight loss, cough, nausea, vomiting, and epigastric pain. She has lived in the Midwest and southwestern US. Presenting labs: TB 1.9 mg/dL, AP 161 U/L, AST 172 U/L, ALT 463 U/L. Workup was negative for COVID, viral/autoimmune hepatitis, sarcoidosis, tuberculosis, and HIV. CT scan showed suspected gallstones and 9 mm left lower lobe noncalcified nodule. EUS showed a normal common bile duct, gallbladder sludge and enlarged porta hepatis lymph nodes which underwent fine needle aspiration (FNA). She was diagnosed with biliary colic and underwent cholecystectomy, with white plaques noted on the liver surface (A). Liver biopsy/FNA showed necrotizing granulomas (B) and fungal yeast on GMS stain (C). Although histoplasmosis urine and blood antigens were negative, histoplasmosis complement fixation was >1:256. She could not tolerate itraconazole for DH, requiring amphotericin B. She then transitioned to voriconazole, discontinued after 5 weeks due to increasing AP. However, her symptoms resolved with normal transaminases. At one year follow up, she is asymptomatic with normal liver function tests. Discussion(s): DH is a systemic granulomatous disease caused by Histoplasma capsulatum endemic to Ohio, Mississippi River Valley, and southeastern US. DH more commonly affects immunocompromised hosts with AIDS, immunosuppressants, and organ transplant. Gastrointestinal involvement is common in DH (70-90%) with liver involvement in 90%. However, granulomatous hepatitis as primary manifestation of DH is rare (4% of liver biopsies). Hepatic granulomas are seen in < 20%. Patients may present with nonspecific systemic symptoms. Serum/urine antigens may be negative. Gold standard for diagnosis is identifying yeast on tissue stains. Recommended treatment is amphotericin B followed by 1 year of itraconazole. However, shorter treatment duration may be effective in immunocompetent hosts. This case is unique in that granulomatous hepatitis was the first presentation of DH in our immunocompetent patient diagnosed on EUS FNA and liver biopsy. Clinicians must have a high degree of suspicion for DH in patients with fever of unknown origin especially in endemic areas regardless of immunologic status. (Table Presented).

Cholelithiasis Causing Asymptomatic Cholecystoenteric Fistula

Introduction: Biliary fistulas are a rare complication of gallstones. Fistula formation can occur in a number of adjacent sites;even more rare complication is the formation of a cholecystocolonic fistula. Case Description/Methods: A 74-year-old man who had recently undergone an extensive hospitalization secondary to inflammatory demyelinating polyneuropathy (IDP) and COVID-19 infection. During his hospitalization, he required ICU admission and mechanical ventilation with subsequent PEG tube placement. He was discharged to an inpatient rehabilitation facility when he developed worsening respiratory distress. Laboratory examinations were pertinent for ALT of 252, AST of 140 and ALP of 401 without hyperbilirubinemia. Blood cultures revealed Escherichia coli bacteremia. Given transaminitis and bacteremia, an MRCP was performed which demonstrated evidence absent space between gallbladder and hepatic flexure of the colon suggesting a CCF (Figure A). An ERCP with sphincterotomy was performed which showed extravasation of contrast from the gallbladder into the colon at the hepatic flexure (Figure B). He underwent cholecystectomy and fistula repair without any complications and gradual improvement in liver function test. He was discharged to a rehabilitation facility. Discussion(s): Complications of gallstones are well established, which include the common bile duct obstruction, but also include the rare occurrences of acute cholangitis, malignancy, and fistula formation. CCF is a rare complication of gallstones which can occur in the stomach, duodenum, or colon with a variable clinical presentation. Complications from an undiagnosed fistula can be life threatening including colon perforation and fecal peritonitis. This case highlights the diagnostic challenge and the high degree of clinical suspicion involved in establishing the diagnosis of CCF in patient without abdominal symptoms suggestive of gallbladder disease. We hypothesize that stone formation resulting in the development of the fistula may be secondary to the underlying history of IDP and subsequent immobility. Although rare, CCF should be considered in patients presenting with unexplained pneumobilia and bacteremia. A timely diagnosis should be made to proceed with immediate treatment including cholecystectomy and fistula closure to prevent fatal complications.

Covid-19 Infection Presenting as Acute Pancreatitis

Purpose of study Introduction COVID-19 emerged at the end of 2019 as an epidemic of respiratory disease in Wuhan, China that later spread globally and was declared as pandemic. The common clinical manifestations of COVID-19 infection include fever, cough, myalgias, headache, sore throat, anosmia, nasal congestion, fatigue and chest pain. The most serious complications include bilateral multifocal pneumonia and acute respiratory distress syndrome. Acute pancreatitis is rarely reported in association with COVID-19 infection. We report a case of acute pancreatitis secondary to COVID-19 infection. Case Report: A 69-year-old man with past medical history of hyperlipidemia and seizure disorder presented with two days of epigastric pain radiating to back. The patient reported fever, malaise and dry cough for the last 3 days. Home medication included atorvastatin and carbamazepine for 10 and 15 years respectively. The patient denied smoking and alcohol use. COVID- 19 PCR was positive. Labs showed WBC of 3800/muL, hgb 11.8 g/dL, calcium 8.4 mg/dL , lipase 426 U/L, D-Dimer 179 ng/ml DDU, High sensitivity C-reactive protein 27.5 mg/L (normal <5 mg/L) ALT 26 U/L, AST 31 U/L, alkaline phosphatase 103 U/L and total bilirubin 0.3 mg/dL. Ultrasound of the right upper quadrant and CT abdomen showed normal pancreas, common bile duct and gallbladder with no evidence of gallstones. Triglyceride level was 70 mg/dL (<149 mg/dL) on the lipid panel. The patient was diagnosed with acute pancreatitis and received treatment with IV fluids and pain medication. The symptoms improved gradually and the patient was discharged home with resumption of home medications. Methods used Case Report Summary of results The common differentials for acute pancreatitis include alcohol use, gallstones, hypertriglyceridemia, viral infections like mumps and measles, hypercalcemia and medication-related, etc. Normal AST, ALT, alkaline phosphatase and total bilirubin along with absence of gallstones and normal common bile duct ruled out alcoholic and biliary pancreatitis. Normal calcium level and triglyceride level rule out hypercalcemia and hypertriglyceridemia as the cause of pancreatitis. Carbamazepine has rarely been reported to cause acute pancreatitis typically soon after the initiating the therapy or with increase in the dose. The use of carbamazepine for more than 15 years without any recent dose change makes this unlikely as the cause of pancreatitis. The onset of acute pancreatitis during the timeline of COVID-19 constitutional symptoms and absence of other risk factors suggests that COVID-19 infection is responsible for acute pancreatitis in our patient. Conclusions We report a case of acute pancreatitis secondary to COVID-19 infection. Further studies are warranted to better understand the etiology and the pathophysiology of acute pancreatitis secondary to COVID-19 infection.

Management of Hepato- biliary-pancreatic Surgery during the COVID-19 Pandemic

Purpose: We examined the effect of COVID-19 on diseases treated with hepato- biliary- pancreatic surgery from the experience of nosocomial infection at our hospital. Method(s): We examined the treatment of 106 patients admitted by the Division of Hepato- Biliary- Pancreatic Surgery to The Jikei University Hospital for elective surgery from January through May 2020. Result(s): Of the 106 operations, 90 (85%) were performed as scheduled and did not include COVID-19-positive patients. Operations for 16 patients (15%) were postponed, but 5 (31%) of these operations were urgent or quasiurgent and were performed during the study period. Of 95 patients who underwent surgery, 50 (53%) had a malignant tumor, 3 (3%) had a borderline malignant tumor, and 42 (44%) had a benign lesion, of which 41 were gallstones or gallbladder polyps and 1 was an intraductal papillary mucinous neoplasm that caused pancreatitis. Surgery for the latter tumor was postponed while conservative treatment improved conditions, but pancreatitis recurred 2 weeks after discharge, leading to a quasiurgent surgery. Conclusion(s): Owing to COVID-19, 15% of the scheduled elective hepato- biliary- pancreatic operations were postponed. Even lesions considered benign or not requiring emergency surgery should be treated promptly. Thus, the timing of treatment should be determined so that the risks of exacerbation and COVID-19 can be balanced.Copyright © 2022 Jikei University School of Medicine. All rights reserved.

General surgery telemedicine clinics: Here to stay post-pandemic?

Background: The telemedicine clinic in general surgery has become widespread since the onset of the COVID-19 pandemic and has remained so following relaxation of restrictions on conventional face-to-face appointments. However, there has been significant scepticism regarding its continued utility. In particular, there is a concern that patients cannot be adequately assessed and counselled for invasive procedures, which may result in high cancellation rates on the day of procedure. The aim of this study was to assess the cancellation rate on the day of surgery for procedures booked in telemedicine clinics. Method(s): We conducted a retrospective analysis of surgical procedures booked via hepatopancreatobiliary (HPB) and general surgery telemedicine clinics from March 2020 to November 2021. From September 2020 onwards, telemedicine clinics were only run for laparoscopic cholecystectomies for benign gallbladder disease. The primary outcome was the cancellation rate of surgical cases booked from telemedicine clinics. Statistical analysis was done using JASP 0.16.2 software. Result(s): We identified 240 cases booked for surgery from telemedicine clinic. 162 patients (68%) were female;the median age of the study population was 51 (16-81). 186 (78%) patients had gallstones, 19 (8%) gallbladder polyps, 13 (5%) secondary liver tumour, 5 (2%) liver cyst, 5 (2%) pancreatic tumour, 4 (1.7%) primary liver tumour, 2 (0.8%) gallbladder tumour and 6 (2.5%) other pathologies. 225 patients (94%) underwent surgery on their first admission. Procedures included 192 cholecystectomies, 10 open segmental liver resections, 6 laparoscopic segmental liver resections, 4 distal pancreatectomies, 3 open right hepatectomies, 2 Whipple procedures, 2 laparoscopic deroofing of the liver cyst, 2 laparoscopic lymph node biopsy, 1 extended right hepatectomy, 1 left hepatectomy, 1 small bowel resection and 1 exploratory laparotomy. 15 (6%) patients had surgery cancelled on the day of surgery, 14 of those were for laparoscopic cholecystectomy, 1 for laparoscopic liver resection. Only one such cancellation was deemed avoidable as it may have been prevented by a face-to-face assessment. The majority 212 (88%) of patients were ASA class 1-2;only 28 (12%) were ASA class 3. There was no significant association between high ASA (3) and cancellation rate (Chi square test 5% vs 14% p=0.062). Conclusion(s): Telemedicine clinic in general surgery was often the only option to assess and plan operative management for newly referred patients during the COVID-19 pandemic. Our series showed that it was feasible to assess and counsel patients on the phone even for major HPB procedures with a minimal cancellation rate on the day of operation.

Covid-19's impact on delays to elective Cholecystectomy

Background: Patients waiting for elective cholecystectomy for symptomatic gallstone disease may need admission with biliary symptoms or complications whilst on the waiting list. The longer the length from listing to procedure the higher the risk of symptoms and possible admission with complications. Many elective operations were cancelled or delayed during the pandemic leading to increased waiting times. The trust noticed a significant number of patients presenting to hospital who were already listed for surgery. This study looks at emergency admission data of 100 patients awaiting elective cholecystectomy. Method(s): Hospital admission data on 100 successive patients from the cholecystectomy waiting list were analysed from Dec 2021-January 2022. Data was collected on when were they added to the list and whether they had presented to hospital in the waiting period before cholecystectomy. Of those that were admitted, reasons for admission, demographics of people who needed admission and length of stay in hospital were recorded. Result(s): Of the 100 patients many had been waiting more than a year with Covid 19 a predominant delaying factor (cholecystectomy is a P3 or P4 procedure and many elective procedures were cancelled or delayed during the pandemic). This cohort of patients had 32 separate presentations to hospital while on the waiting list (some patients presenting multiple times). 9 patients required emergency hospital admission for clinical reasons such as pancreatitis and cholecystitis. This totaled 67 bed days for the admitting hospital, some data was unavailable due to admissions to other hospitals. Conclusion(s): NICE guidelines recommend laparoscopic cholecystectomy within 1 week for patients presenting with acute gallstone disease. Early elective cholecystectomy is recommended for patients with symptomatic gallstones. Delays in elective cholecystectomy operations during Covid 19 have caused delays to definitive treatment and led to excess bed usage during the treatment pathway with the associated financial costs and patient morbidity.

Index admission cholecystectomy with or without single session bile duct exploration for Emergency gall stone complications neutralised the adverse effects of COVID

Aims: The COVID-19 pandemic impacted surgical practice globally. We aim to study The effects this had on The presentations, practice and results of Biliary Surgery on a unit adopting index admission laparoscopic cholecystectomy (LC) and single session management of bile duct stones for Emergency presentations. Method(s): Prospectively collected data of Biliary Surgery over a period of 12 months pre-COVID (PRE) and 12 months post-COVID (PoST) was analysed. The presentation, type of admission, type of operating list and operative and postoperative data were compared. Result(s): 257 LCs were done PRE and 270 PoSt. All Emergency presentations increased;acute cholecystitis 8.5% to 25.9%, acute pancreatitis 6.2% to 11.8% and jaundice 22.5% to 27.7%. Elective LC decreased from 53% to 20%. With an increase in patients with previous admissions (13.6% PRE vs 20.7% PoST), 87% of PRE vs 80% PoST had index admission LC, utilising 192 Emergency theatre sessions and 29 CEpoD lists. In spite of increased LC difficulty grades (grades 4 and 5 from 20.2% to 30.5%), bile duct explorations (34%), operating time and median total hospital stay The morbidity, mortality and median presentation to resolution intervals were not affected. Conclusion(s): COVID-19 caused an increase in all acute Biliary presentations requiring Emergency admissions, almost certainly The result of a significant decline in elective LC. However, similar numbers of LC PRE and PoST were maintained due to a policy of index admission Surgery and bile duct exploration, utilising Emergency theatre scheduling, optimised clinical outcomes in spite of some logistical parameters being affected.

Pay per View: Cost and Satisfaction of Virtual Video Clinics

Aims: The COVID-19 pandemic necessitated use of video consultations to provide continued patient care. It is not clear if video clinics are well received by patients, or if they are cost efficient. We evaluate The benefits of video consultation and review The impact on waiting times and cost implications to a trust. Method(s): 100 patients referred between January-December 2021 with gallstones were invited to complete a patient satisfaction questionnaire after initial clinic consultation. Patients were divided into three groups based on consultation type;face-to-face, telephone and video consultation (via The Attend Anywhere platform). Secondary outcome measures included time from referral to appointment, time to final outcome and cost implications. Result(s): 93 patients responded;33 video, 30 face-to-face and 30 telephone consultations. Of these patients 62% were female and 38% male with an average age of 51 (25-84). Average time from referral was 22 days in The video cohort, 22 in The telephone cohort and 32 for face-to-face appointments. Of The video cohort, 44% were booked for cholecystectomy from initial consultation and 56% sent for further investigation. The conversion rate from video to face-to-face consultation was zero. 50% of respondents stated face-to-face consultations as their preferred method of future consultation, 49% of patients opted for video and 1% preferred telephone consultation. 79% reported increased satisfaction due to convenience of consultation. Conclusion(s): This study demonstrates video consultations decrease costs and waiting times. Patient satisfaction is comparable to inperson visit. Specific referral criteria and patient selection is essential to maximise The benefits of video consultations.

Comparing Cholecystectomy Day Case Rates during the pre-COVID and COVID Era at a Rural District General Hospital

Aims: 67 000 cholecystectomies performed every year in The UK and 92% are laparoscopic. 75% of operations should be done as day cases. National rates vary between 6-50% with The most successful centres at 70%. Our aim was to audit The day case rate at our Trust pre-COVID and compare it to during COVID. Method(s): A retrospective audit of patients identified via clinical coding who had an elective cholecystectomy at one hospital in The Trust between 1 December 2018 to 31 November 2019. During COVID we did a prospective audit of patients identified via Theatreman who had an elective cholecystectomy at The Trust's designated "Green Hospital" between 21 September 2020 to 21 December 2020. Data for all patients was collected from electronic discharge summaries, clinic letters and patient notes. Result(s): Pre-COVID our day case cholecystectomy rate was 73% compared to 54.7% during COVID. Pre-COVID conversion rate from planned day case to inpatient stay was 16.3% and during COVID The conversion rate increased to 44%. The waiting time for a cholecystectomy doubled during COVID to 26.3 weeks from 13.6 weeks pre-COVID. Average re-admission rate with symptomatic gallstones was 0.79 pre-COVID and 0.95 during COVID, with 64% of patients having at lEast one admission prior to surgery. The average length of stay pre-COVID was 0.75 days compared to 0.57 days during COVID. Summary: COVID adversely affected our day case cholecystectomy rates with resultant increased waiting times for Surgery and readmissions with symptomatic gallstones however The average length of hospital stay was reduced.

Financial implications of gallstone-related complications whilst awaiting elective cholecystectomy: A single institution experience of 900 patients

Aims: Over 65,000 cholecystectomies are performed each year in The United Kingdom with increasing waiting-list times due to The CoVID-19 pandemic. This study set out to understand The cost to The NHS of complications experienced whilst awaiting cholecystectomy. Method(s): A retrospective cohort study was carried out for all patients who had been awaiting elective cholecystectomy for more than 20 weeks On The 17th September 2021 at a large NHS Foundation Trust. Demographic data was collected at The time of listing. Re-admission data was collected from patient notes. It included clinical history, blood results and imaging investigations. Associated costs were calculated. Result(s): 900 patients included in The study (median age 56 years, 71.7% female). 138 patients (15.3%) re-presented to hospital whilst On The waiting list with complications of gallstone disease. Of these, 51 had more than one presentation to hospital with 18 patients having more than three presentations. This was equivalent to 625 days in hospital, with only 79 same day discharges, and multiple investigations were performed (ultrasound scan = 79;CT scan = 31, MRCp = 47, ERCp = 21). This was estimated to have cost a minimum of 364,917. Assuming an average time for an elective cholecystectomy of 90 mins at a cost of 1,200 per hour, 202 additional cholecystectomies could have been performed. Conclusion(s): This study highlights The enormous potential to reduce patient suffering by increasing The number of elective cholecystectomy lists, and at no overall additional cost to The trust.

SARS-CoV-2 pandemic has impacted on patterns of aetiology for acute pancreatitis and management of gallstone pancreatitis in the United Kingdom

Introduction: The impact of the SARS-CoV-2 pandemic on patterns of aetiology of acute pancreatitis (AP) and management of AP in the UK is unknown. Method(s): A prospective multicentre cohort study of consecutive patients admitted with AP between 01/03/2020 and 23/07/2020 was undertaken. Patients were followed up for 12 months. Result(s): 1628 patients presenting with AP were included in the analysis. Gallstones (GSP) were the predominant aetiology (43.6%), followed by alcohol associated (25.8) and idiopathic (21.5%) AP. After completing aetiological investigations, 14.4% of the idiopathic cohort remained to have an idiopathic aetiology. 113/187 patients were readmitted during the 'second wave' of SARS-CoV-2 pandemic (after September 2020) with predominantly alcohol-related AP aetiology (49, 43.3%). Patients readmitted during the 'second wave', more commonly had alcoholic AP compared to the index cohort (43.4% vs 23.5% respectively;p<0.001);however, there were no significant differences in AP severity (p=0.268). Of the 1358 patients with complete follow-up data, 620 (45.7%) presented with GSP of which only 66 (10.6%) underwent index cholecystectomy and 108 (17.4%) had an interval cholecystectomy with median waiting time of 32 days (IQR 16-56). Accounting for 44/456 patients with previous cholecystectomies, and 24 patients deemed unfit for cholecystectomy, the remaining 388 (77.3%) were still awaiting cholecystectomy at the end of 12 months. Conclusion(s): The patterns of aetiology for AP changed during the SARS-CoV-2 pandemic with an increase in alcohol associated AP. Most significantly, access to cholecystectomy was restricted during the pandemic and readmission to hospital may have been driven by the need for cholecystectomy. Take-home message: The patterns of aetiology for AP changed during the SARS-CoV-2 pandemic with an increase in alcohol associated AP. Most significantly, access to cholecystectomy was restricted during the pandemic and readmission to hospital may have been driven by the need for cholecystectomy.

A PROBABLE CASE OF IGG4-RELATED LUNG DISEASE MIMICKING PNEUMOCONIOSIS

SESSION TITLE: Autoimmune Diseases Gone Wild: Rare Cases of Pulmonary Manifestations SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/18/2022 01:35 pm - 02:35 pm INTRODUCTION: Immunoglobulin G4-related disease (IgG4-RD) is a complex entity related to autoimmune dysfunction and inflammation that can cause mass-like lesions and fibrosis of a variety of organs, including pancreas and/or lungs. IgG4-RD in the lung can have diverse clinical and radiographic presentations. We present a case of suspected IgG4-RD that manifested as idiopathic pancreatitis and interstitial lung disease that mimicked coal workers' pneumoconiosis. CASE PRESENTATION: A 72 year-old male with a decades-long coal mining history and a presumptive diagnosis of coal-worker's pneumoconiosis was admitted to the hospital for necrotizing pancreatitis. There was no evidence of gallstones, elevated triglycerides, history of alcohol use or medication known to precipitate pancreatitis. Two years prior, a presumptive diagnosis of coal-worker's pneumoconiosis had been reached largely on the basis of history and chest imaging (Figure 1) showing a progressive massive pulmonary fibrosis pattern. His hospital course was protracted and complicated by nosocomial COVID-19 treated with remdesivir and a 10-day course of dexamethasone. He then had persistent hypoxemia that worsened after dexamethasone was discontinued. Empiric high-dose methylprednisolone was given and the hypoxemia improved dramatically. However, the hypoxemia and pancreatitis repeatedly worsened with significant dose decrease. Inpatient CT chest showed worsening interstitial reticulation and ground-glass opacities superimposed on prior fibrosis (Figure 2). Serum IgG subclass levels were checked;IgG4 and IgG4:IgG ratio were mildly elevated at 93mg/dL and 0.09, respectively. In the setting of idiopathic pancreatitis, pulmonary fibrosis, and steroid-sensitive hypoxemia, he was diagnosed with probable IgG4-RD involving pancreas and lungs. An association between inhaled occupational exposures and development of IgG4-RD has been observed. To confirm the diagnosis of pulmonary IgG4-RD, a tissue biopsy will be necessary. He is now discharged from hospital on a long steroid taper. DISCUSSION: A serum IgG4 level >125mg/dL or an IgG4:total IgG ratio >0.08 support the diagnosis, as does clinical response to steroids. However, these criteria are nonspecific and will be in the normal range in a substantial minority of cases. Lymphocytes and a predominance of IgG4-positive plasma cells infiltrating fibrotic tissue in involved organs are pathologic hallmarks of IgG4-RD. Lung involvement in patients with pancreatitis due to IgG4-RD is common and likely under recognized. CONCLUSIONS: Pulmonary involvement in IgG4-RD can show a wide array of radiographic patterns, but that seen in this case with pseudotumor and fibrosis is among the most commonly reported. Given the overlap in risk factors and radiographic appearance between IgG4-RD and pneumoconiosis, vigilance for IgG4-RD is warranted. Reference #1: Hirano K., Kawabe T., Komatsu Y., et al.

Service Evaluation of the Management of Acute Cholecystitis in the Royal Gwent Hospital Pre and During the COVID-19 Pandemic

Aim: NICE guidelines set out the criteria for the treatment of patients with acute cholecystitis and the operative timescales for cholecystectomy. These targets were greatly affected during the Covid-19 pandemic. Therefore, we aimed to assess the impact that COVID-19 had on patients presenting with acute cholecystitis at a busy district general hospital. June 2020, compared with patients who presented with the same in June 2019. Method: Patient cohorts were identified for matching seasons pre- and post-covid-19 (June 2019 and June 2020). Data of all patients who presented with acute cholecystitis was obtained using an electronic patient management system. Statistical analyses were performed using a Wilcoxon test. Results: The results of the study indicate that waiting times post-covid are going down (p<0.05). Thus, days until cholecystectomy have decreased but the number of patients being operated on too has decreased thus further worsening waiting times for elective patients. The median and IQR's of days to surgery post-covid are 198 (121.5-278) and pre-covid are 251 (89.5-586.5). Presentations of gallstone complications almost doubled post-covid and the percentage of patients operated on decreased by over 20%. Conclusions: It is clear from the data that the NICE guidance on the management of acute cholecystitis has been difficult to adhere to during the pandemic. While the time from diagnosis to operation has reduced post-covid the total number of operations has decreased drastically, putting further strain on elective waiting lists. This, inevitably, will result in further presentations of complications from gallstones and adverse patient outcomes.

Acute Necrotizing Pancreatitis in COVID-19 Disease: A Case Report

Aims and objectives: Gastrointestinal symptoms like abdominal pain can be atypical presentations associated with coronavirus disease. This case report describes the presentation of acute pancreatitis in a patient with moderate COVID-19 infection. Materials and methods: Data were collected from a patient who was admitted with acute pancreatitis as sequelae of COVID-19 infection in our intensive care unit in June 2021. Case presentation: A 25-year-old female with no comorbidities presented to our emergency department with complaints of fever and dry cough for 10 days for which she had taken treatment at home. COVID RTPCR was negative and CT severity was 10/25. She also complained of abdominal pain with vomiting for 2 days. So she was admitted to our hospital on the tenth day of her illness. Laboratory analysis showed >3 times elevation of serum lipase. CT abdomen showed acute pancreatitis with gallbladder sludge. Causes of pancreatitis like gallbladder stones, alcohol, hypercalcemia, and hypertriglyceridemia were excluded by history and investigations. She was diagnosed with acute pancreatitis due to COVID-19. C-reactive protein and D dimer was highly elevated. She was admitted in ICU and was started on conservative management with IV fluids and bowel rest. Oral intake was resumed gradually as tolerated. The patient was maintaining adequate oxygen saturation on room air. Her repeat COVID RTPCR was again negative. However, her CT severity had increased to 14/25. Her total antibody SARS-CoV-2 was highly reactive. She had severe pain which was not improving despite multimodal analgesia which included opioid infusion. She had bilateral minimal pleural effusion and consolidation and required 2-4 L oxygen support. Repeat CT abdomen after a week showed acute necrotizing pancreatitis with gross pancreatic ascites and partial splenic vein thrombosis (modified CT severity index 8). On day 7 of admission, she developed a fever. Blood and urine cultures were sent and empirical antibiotic was started. Urine culture showed Klebsiella pneumoniae and antibiotic was escalated as per sensitivity pattern. Her pain scores persisted to be high despite all measures. On day 14, she developed abdominal distension. Intra-abdominal pressures were normal and repeat CT abdomen showed extensive free fluid with dilated bowel loops which was likely paralytic ileus. A CT-guided pigtail was inserted for continuous drainage of fluid. The ascitic fluid culture showed no organism. Her abdominal distension gradually reduced. We tapered the requirement of opioids day by day and she got symptomatically better. She could tolerate oral feeds better, off oxygen support, and was shifted to wards with pigtail catheter in situ. She stayed in ICU for 26 days. She was doing better in wards and was discharged home after 5 days with oral anticoagulant and other symptomatic medications and was adviced for gastroenterology follow-up after 10 days. Results: A patient was diagnosed with acute pancreatitis associated with SARS-CoV-2 and was treated accordingly. Other causes of acute pancreatitis were excluded in the patient including alcohol, biliary obstruction/gall stones, drugs, trauma, hypertriglyceridemia, hypercalcemia, and hypotension. Conclusion: This case highlights acute pancreatitis as a complication associated with COVID-19 and underlines the importance of evaluating and treating patients with COVID-19 and abdominal pain.

TIGECYCLINE INDUCED ACUTE PANCREATITIS: A RARE CASE PRESENTATION

CASE: An 81-year-old female with multiple co-morbidities including recent covid-19, presented to the emergency room with shortness of breath. On arrival, she was febrile with a temperature of 101F, pulse 100 beats/min, respiratory rate 14, blood pressure 196/163 and saturating at 75% on 10 L non-rebreather mask. Initial blood work showed WBC 10.9, lactic acid 1.7, BUN/creatinine 27/1.7 (consistent with her baseline), ABG showed pH 7.37, PCO2 49, PO2 88, HCO3 27.9. Chest x-ray demonstrated volume loss in the left hemithorax, airspace disease in the left mid lung and lung base. Due to suspicion for superimposed bacterial pneumonia and positive blood cultures for staphylococcus haemolyticus, she was started on vancomycin and azithromycin. Choice of antibiotics was challenging as she was allergic to penicillin and cephalosporins. During hospitalization, her kidney function deteriorated, vancomycin was substituted with tigecycline on day 3. Day 5 of treatment, she developed multiple episodes of vomiting with epigastric pain, lipase was 4523. Acute pancreatitis was diagnosed with tigecycline presumed to be the inciting agent in the absence of other risk factors such as gall stones, chronic alcohol use, elevated triglycerides, previous known episodes of pancreatitis or any other causative medications. Tigecycline was switched back to vancomycin and she received aggressive IV fluid hydration which also improved her kidney function. Within 48 hours, the patient had improved oxygen saturation, resolution of her abdominal pain, and good oral intake marking significant overall clinical progress. She was discharged on home oxygen and few more days of IV vancomycin for bacteremia. IMPACT/DISCUSSION: Tigecycline is a broad-spectrum glycylcycline antimicrobial agent belonging to the tetracycline class of antibiotics. Tetracyclines have been associated with acute pancreatitis in literature, and concerns about tigecycline-induced acute pancreatitis have been raised over the past decade in post marketing surveys, we described one such case above. Using the Naranjo Adverse Drug reaction probability scale, a score of 6 was achieved, indicating that the patient's pancreatitis was probably related to tigecycline. CONCLUSION: We recommend physicians monitor patients for signs and symptoms of pancreatitis including abdominal pain after initiating treatment with tigecycline. There should be a low threshold for ordering lipase levels and abdominal CT imaging where indicated. If the patient has symptoms concerning for acute pancreatitis, consider stopping tigecycline and switching to a different class of antibiotics immediately.
