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.

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.

SARS-CoV-2-related injury of biliary tract

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), which causes coronavirus disease-2019 (COVID-19), affects several organs and systems. The ways of the virus penetration into tissues have been studied. Liver is affected in 15 — 53 % of cases. Data on the RNA-seq sequencing in the Human Protein Atlas database con-firm the expression of ACE2 (angiotensin 2 converting enzyme receptor) in the liver and epithelium of the bile ducts and gallbladder. At the same time, a high frequency of ACE2 expression is observed only in cholangiocytes, but not in hepatocytes, Kupffer cells or endothelial cells. The amount of ACE2 in bile duct cells is significantly higher than in hepatocytes, and is comparable to the level in type 2 alveolar cells in the lungs, which makes the biliary tract a potential target for the virus. Binding of SARS-CoV-2 to gallbladder epithelial cells can lead to mucosal inflammation. A systematic review describes the formation of bile clots in small bile ducts. Presence of COVID-19 in the wall of the gallbladder (qrt-RCR) has been revealed. With this, acute cholecystitis develops clinically, and radiological investigations show thickening of the gallbladder wall, biliary sludge and perivesicular fluid. Onset of acute gangrenous cholecystitis as a late complication of COVID-19 infection is described. Histologically, inflammatory infiltrates are found in the gallbladder wall, which diffusely affect medium-sized arteries with obliteration of their lumen, ischemia of the bladder wall;the perineural inflammation take place. These features indicate vasculitis with thrombosis. Thus, despite the theoretical information about the biliary tract injury by the COVID-19 virus, this aspect of the infection has not been clinically studied, and the published papers are limited to the description of single clinical cases. In our opinion, a deeper and long-term study of the biliary tract pathology in COVID-19 infection is needed to provide rationale for the treatment with ursodeoxycholic acid. © 2020, Publishing Company VIT-A-POL.

Acute acalculous cholecystitis as a rare gastroenterological association of COVID-19: a case series and systematic review.

Background and Aim: Acute acalculous cholecystitis (AAC) is an acute inflammatory disease of the gallbladder in the absence of cholecystolithiasis. It is a serious clinicopathologic entity, with a high mortality rate of 30-50%. A number of etiologies have been identified that can potentially trigger AAC. However, clinical evidence on its occurrence following COVID-19 remains scarce. We aim to evaluate the association between COVID-19 and AAC. Methods: We report our clinical experience based on 3 patients who were diagnosed with AAC secondary to COVID-19. A systematic review of the MEDLINE, Google Scholar, Scopus, and Embase databases was conducted for English-only studies. The latest search date was December 20, 2022. Specific search terms were used regarding AAC and COVID-19, with all associated permutations. Articles that fulfilled the inclusion criteria were screened, and 23 studies were selected for a quantitative analysis. Results: A total of 31 case reports (level of clinical evidence: IV) of AAC related to COVID-19 were included. The mean age of patients was 64.7 ± 14.8 years, with a male-to-female ratio of 2.1:1. Major clinical presentations included fever 18 (58.0%), abdominal pain 16 (51.6%), and cough 6 (19.3%). Hypertension 17 (54.8%), diabetes mellitus 5 (16.1%), and cardiac disease 5 (16.1%) were among the common comorbid conditions. COVID-19 pneumonia was encountered before, after, or concurrently with AAC in 17 (54.8%), 10 (32.2%), and 4 (12.9%) patients, respectively. Coagulopathy was noted in 9 (29.0%) patients. Imaging studies for AAC included computed tomography scan and ultrasonography in 21 (67.7%) and 8 (25.8%) cases, respectively. Based on the Tokyo Guidelines 2018 criteria for severity, 22 (70.9%) had grade II and 9 (29.0%) patients had grade I cholecystitis. Treatment included surgical intervention in 17 (54.8%), conservative management alone in 8 (25.8%), and percutaneous transhepatic gallbladder drainage in 6 (19.3%) patients. Clinical recovery was achieved in 29 (93.5%) patients. Gallbladder perforation was encountered as a sequela in 4 (12.9%) patients. The mortality rate in patients with AAC following COVID-19 was 6.5%. Conclusions: We report AAC as an uncommon but important gastroenterological complication following COVID-19. Clinicians should remain vigilant for COVID-19 as a possible trigger of AAC. Early diagnosis and appropriate treatment can potentially save patients from morbidity and mortality. Relevance for Patients: AAC can occur in association with COVID-19. If left undiagnosed, it may adversely impact the clinical course and outcomes of patients. Therefore, it should be considered among the differential diagnoses of the right upper abdominal pain in these patients. Gangrenous cholecystitis can often be encountered in this setting, necessitating an aggressive treatment approach. Our results point out the clinical importance of raising awareness about this biliary complication of COVID-19, which will aid in early diagnosis and appropriate clinical management.

Comparison of severity and complication rates of acute cholecystitis during pandemic and pre-pandemic periods?

BACKGROUND: Cancellations of surgeries for elective cases and late admissions of symptomatic cases during the pandemic period might have increased the number of cases of acute cholecystitis and its complications. PURPOSE: To compare the severity of acute cholecystitis and complication rates during the pandemic and pre-pandemic periods. MATERIAL AND METHODS: We evaluated the computed tomography (CT) findings observed for the diagnosis of complications for both acute simple and acute complicated cholecystitis during both the pandemic and pre-pandemic periods. Patients admitted to the hospital between March 2020 and December 2020 made up the study group and the corresponding appropriate patients from one year earlier were studied as the control group. In addition to the CT findings, clinical and laboratory findings, co-morbidities such as diabetes, as well as the admission time to hospital from the onset of the initial symptoms to hospital admission were also evaluated. RESULTS: A total of 88 patients were evaluated (54 in the study group, 34 in the control group; mean age = 64.3 ± 16.3 years). The male-to-female ratio was 51/37. The number of patients diagnosed with complicated cholecystitis were significantly higher in the study group (P = 0.03). Murphy finding and diabetes status were similar between the two groups (P = 0.086 and P = 0.308, respectively). Admission time to the hospital was significantly different for study and control groups in simple cholecystitis patients (P = 0.045); with no significant difference in cases of complicated cholecystitis (P = 0.499). CONCLUSION: Our study reveals the course of acute cholecystitis during the pandemic period was much more serious with higher complications.

A rare case of central post-stroke pain in a patient with migraine and lacunar infarcts in the medulla oblongata

Studies about headaches associated with acute ischemic stroke in patients suffering from migraine were limited, and therefore we present a clinical case of central post-stroke pain (CPSP) in a 47-year-old woman with migraine and lacunar infarcts in the medulla oblongata and also possible mechanisms of CPSP in patients with migraine. Magnetic resonance imaging of the brain revealed lacunar infarction in the medulla oblongata on the right (vertebral artery basin) and a single focus of gliosis in the parietal lobe on the right. Magnetic resonance angiography of cerebral vessels showed the fetal type of structure of both posterior cerebral arteries. This clinical case is a complex clinical situation of a combination of secondary headaches (post-stroke) in a patient with a primary headache (migraine), which was successfully treated by the combined administration of first-line drugs for the treatment of neuropathic pain in a patient with lacunar infarcts in the medulla oblongata. The treatment of CPSP is a difficult task due to the insufficiently unexplored mechanisms of development, the most effective approaches are those aimed at reducing the increased excitability of neurons.Copyright © 2023, Indian Association of Biomedical Scientists.

Glial fibrillary acidic protein astrocytopathy in a patient with recent mRNA SARS-CoV-2 vaccination: COVERSHEET

Background: Literature describing triggers of GFAP astrocytopathy (GFAP-A) is limited. We report a case of GFAP-A in a patient with recent messenger ribonucleic acid (mRNA) severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) vaccination and discuss the possible pathogenesis. Case description: A 45-year-old gentleman presented with features of meningoencephalitis 31 days after the first dose and 4 days after the second dose of mRNA SARS-CoV-2 vaccination. He sequentially developed brainstem/cerebellar, autonomic and cord dysfunction. Cerebrospinal fluid was positive for GFAP autoantibody. Clinical improvement occurred after intravenous methylprednisolone and immunoglobulins. Conclusion(s): Although we are uncertain of a causal link of GFAP-A to mRNA vaccine, indirect activation of an underlying dysregulated immune milieu is plausible.Copyright © 2021 The Author(s)

A surprising culprit for delayed gastrointestinal bleeding after endoscopic ultrasound-guided cholecystoduodenostomy: the double-pigtail stent.

Endoscopic ultrasound-guided gallbladder drainage using a lumen-apposing metal stent has emerged as an accepted option for the treatment of acute cholecystitis in patients unfit for surgery. While metal stents carry a risk of intra- and post-procedural bleeding, the coaxial placement of a double-pigtail stents through lumen-apposing metal stents has been proposed to lower the bleeding risk by preventing tissue abrasion against the stent flanges. We present a case of an 83 year-old male who had previously undergone uncomplicated endoscopic ultrasound-guided cholecystoduodenostomy with this technique. Six months later, he presented with upper gastrointestinal bleeding due to a duodenal pressure ulcer from the coaxial 10-Fr double-pigtail stent originally employed to prevent such bleeding. The 10-Fr stent was replaced with two 7-Fr stents whose increased flexibility and distribution of pressure across multiple points of contact with the duodenal wall was theorized to reduce the likelihood of erosion or perforation. Following the procedure, the patient's clinical course improved significantly with complete resolution of his symptoms of choledocholithiasis and cholecystitis. While 10-Fr double-pigtail stents are generally preferred for this indication due to their stiffness that reduces out-migration, use of more flexible 7-Fr stents may be advisable in thin-walled structures such as the duodenum.

"Inside out" - An exceptional intussusception

Introduction: We present the first case of appendiceal intussusception associated with myeloid sarcoma in a young patient. Minimally invasive techniques used along the clinical course are highlighted. Case description: A 2.5-year-old boy was admitted after three weeks of COVID-19 infection with ongoing symptoms of MIS-C. Due to constipation, distended belly and vomiting, US was done which showed ileocolic intussusception. After unsuccessful hydrostatic reduction laparoscopic exploration was performed, where the vermiform appendix was found to be thickened and partially intussuscepted into the coecum. The ileocecal region was exteriorized transumbilically. After manual reduction of the intussusception, a long, thickened, fragile appendix was removed. Histopathology revealed myeloid sarcoma. Bone marrow investigation identified acute myeloid leukemia. During the oncological treatment, laparoscopic cholecystectomy was necessary due to cholecystitis and cholelithiasis. The child recovered uneventfully in terms of surgical complications, with good cosmetic result. Conclusion(s): No similar case in childhood was found in the English literature. Unusual symptoms and radiological findings of intussusception can conceal unexpected disorders. Minimally invasive technique offered advantages in the treatment of the presented patient and can be recommended to treat intussusception or cholelithiasis, if applicable, during an ongoing oncological treatment as well.Copyright © 2023 The Authors

A Surgical Perspective of Gastrointestinal Manifestations and Complications of COVID-19 Infection.

The coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2, has quickly spread over the world since December 2019. COVID-19 is a systemic disease that can affect various organs throughout the body. Gastrointestinal (GI) symptoms have been reported in 16% to 33% of all patients with COVID-19 and in 75% of critically ill patients. This chapter reviews the GI manifestations of COVID-19 as well as their diagnostic and treatment modalities.

Impact of COVID-19 outbreak on acute gallbladder disease in the emergency department.

OBJECTIVE: Acute gallbladder disease (AGD) is frequent in the emergency department (ED) and usually requires emergency surgery. However, only a few studies have reported the impact of COVID-19 on AGD. The goal of this study was to evaluate the time between symptom onset and surgery and the perioperative severity of AGD during the COVID-19 pandemic compared to before the era of COVID-19. METHODS: This retrospective, single-center cohort study included patients who presented to the ED with suspected AGD and who underwent emergency cholecystectomy. We designed a before-after comparative study, and the intervention was the COVID-19 outbreak. The 6-month period after the COVID-19 outbreak was defined as the post-COVID group, whereas the pre-COVID group consisted of the same period in the previous year. The primary outcome was the time from symptoms to surgery. We evaluated the time intervals between symptom onset and ED arrival and between ED arrival and surgery. The secondary outcomes were preoperative and postoperative severity indexes. RESULTS: A total of 316 patients was analyzed. The post-COVID group showed longer duration from symptom onset to ED arrival (34.0 hours vs. 15.0 hours, P<0.001) and longer time interval from ED arrival to surgery (16.2 hours vs. 10.2 hours, P<0.001) than the pre-COVID group. The overall time interval between symptom onset to surgery was longer in the post-COVID group than the pre-COVID group (71.5 hours vs. 33.5 hours, P<0.001). The post-COVID group showed higher preoperative Simplified Acute Physiology Score II scores than the pre-COVID group (20.1 vs. 18.2, P=0.045). The proportion of moderate or severe disease increased in the post-COVID group (78% vs. 65%, P=0.017). The durations of hospital stay (7.0 days vs. 5.0 days, P<0.001) and intensive care unit stay (27.1 hours vs. 10.8 hours, P=0.008) were longer in the post-COVID group than in the pre-COVID group. CONCLUSION: During the pandemic, the time interval between symptom onset to surgery was significantly increased among patients with AGD. Concomitantly, higher preoperative severity indexes and longer hospital stay were reported with a delay in emergency surgery.

Beware of Rattling Underfoot: Cystic Artery Pseudoaneurysm in Acute Cholecystitis With a Cholecystostomy.

Cystic artery pseudoaneurysm (CAP) is a very rare complication of acute cholecystitis. The pathogenesis of CAP in the context of cholecystitis is unknown but is possibly related to the inflammatory process in the vicinity of the cystic artery, leading to weakness in the wall of the artery. Though CAP has been reported in the literature, our patient had a unique presentation in the presence of a cholecystostomy catheter in situ. There were no risk factors for CAP in our patient including usage of anticoagulants, trauma, or surgical procedures. Fortunately, the blood-stained fluid in the cholecystostomy catheter effluent alerted the clinical team to a possible vascular complication in the background of ongoing cholecystitis. This finding should serve as a warning sign to alert clinicians to the possibility of CAP-beware of rattling underfoot.

COVID-19 associated spontaneous hemorrhagic cholecystitis

Hemorrhagic cholecystitis is a rare disorder associated with considerable morbidity and mortality. The clinical presentation of hemorrhagic cholecystitis is non-specific and imaging findings can be difficult to accurately interpret without a high level of suspicion. Most recent reports of hemorrhagic cholecystitis have been associated with concurrent therapeutic anticoagulation. Here, we report imaging findings of a case of acute, spontaneous hemorrhagic cholecystitis in a 67-year-old male patient admitted for hypoxic respiratory failure secondary to COVID-19 pneumonia. © 2022

The ChoCO-W prospective observational global study: Does COVID-19 increase gangrenous cholecystitis?

BACKGROUND: The incidence of the highly morbid and potentially lethal gangrenous cholecystitis was reportedly increased during the COVID-19 pandemic. The aim of the ChoCO-W study was to compare the clinical findings and outcomes of acute cholecystitis in patients who had COVID-19 disease with those who did not. METHODS: Data were prospectively collected over 6 months (October 1, 2020, to April 30, 2021) with 1-month follow-up. In October 2020, Delta variant of SARS CoV-2 was isolated for the first time. Demographic and clinical data were analyzed and reported according to the STROBE guidelines. Baseline characteristics and clinical outcomes of patients who had COVID-19 were compared with those who did not. RESULTS: A total of 2893 patients, from 42 countries, 218 centers, involved, with a median age of 61.3 (SD: 17.39) years were prospectively enrolled in this study; 1481 (51%) patients were males. One hundred and eighty (6.9%) patients were COVID-19 positive, while 2412 (93.1%) were negative. Concomitant preexisting diseases including cardiovascular diseases (p < 0.0001), diabetes (p < 0.0001), and severe chronic obstructive airway disease (p = 0.005) were significantly more frequent in the COVID-19 group. Markers of sepsis severity including ARDS (p < 0.0001), PIPAS score (p < 0.0001), WSES sepsis score (p < 0.0001), qSOFA (p < 0.0001), and Tokyo classification of severity of acute cholecystitis (p < 0.0001) were significantly higher in the COVID-19 group. The COVID-19 group had significantly higher postoperative complications (32.2% compared with 11.7%, p < 0.0001), longer mean hospital stay (13.21 compared with 6.51 days, p < 0.0001), and mortality rate (13.4% compared with 1.7%, p < 0.0001). The incidence of gangrenous cholecystitis was doubled in the COVID-19 group (40.7% compared with 22.3%). The mean wall thickness of the gallbladder was significantly higher in the COVID-19 group [6.32 (SD: 2.44) mm compared with 5.4 (SD: 3.45) mm; p < 0.0001]. CONCLUSIONS: The incidence of gangrenous cholecystitis is higher in COVID patients compared with non-COVID patients admitted to the emergency department with acute cholecystitis. Gangrenous cholecystitis in COVID patients is associated with high-grade Clavien-Dindo postoperative complications, longer hospital stay and higher mortality rate. The open cholecystectomy rate is higher in COVID compared with non -COVID patients. It is recommended to delay the surgical treatment in COVID patients, when it is possible, to decrease morbidity and mortality rates. COVID-19 infection and gangrenous cholecystistis are not absolute contraindications to perform laparoscopic cholecystectomy, in a case by case evaluation, in expert hands.

Acalculous Cholecystitis: A Novel and Lethal Unrecognized Complication in Severe CoVID 19

Background. SARS-COV-2 infection is known to cause tissue damage in several organs outside of the respiratory tract. The pathogenesis of tissue damage is hypothesized to be caused by direct viral damage, endothelial injury, and ischemic or thrombotic events. Gastrointestinal symptoms were first characterized mainly as diarrhea and diffuse abdominal pain and discomfort, which can be hard to interpret in the setting of a generalized inflammatory response;gallbladder injury and inflammation causing acute acalculous cholecystitis has been scarcely reported Methods. Here we discuss five cases of patients presenting with symptoms of cholecystitis. All five patients underwent multiple imaging studies, and all of them were compatible with acute cholecystitis;some of them had an imaging report of lithiasic cholecystitis, while the rest were reported with microlithiasis or biliary sludge. Four out of the five patients underwent laparoscopic cholecystectomy;biopsies were taken, consistently those reported with acalculous cholecystitis. The remaining patient died of CoVID 19 complications prior to surgery, but after a percutaneous cholecystostomy tube was placed. Results. All these patients have in common the prolonged fasting, because they all required invasive mechanical ventilation, consequently, they all developed multiple focal pneumonia and respiratory distress syndrome. This fast is related to the development of gangrenous ischemia in the gallbladder, which manifests as a late complication due to SARS-CoV-2 infection, in addition to being related to angiotensin-2 converting receptors and virus replication proteins, as well as the pro-inflammatory and hypoxia state that in itself causes the infection (9). All showed a cholestatic pattern, highlighting that this complication developed in an average time of 3 weeks after the onset of SARS-CoV2 symptoms, in addition to the fact that in most cases a negative test was already shown at the time of the complication. Conclusion. Acalculous cholecystitis is one of the extrapulmonary complications that has been seen in patients with this infection, not being the most common, but one of those that has generated a higher mortality rate in patients due to its late diagnosis and non-specific clinical picture in certain occasions (9).

Management of Obstructive Jaundice in Patients with Periampullary Tumors in a Covid-19 Pandemic Situation

Introduction: The redistribution of hospital resources secondary to SARS-CoV-2(COVID19) produced a reduction and delay in surgical activity. Analysis of the management of obstructive jaundice (OI) in a reference centre during COVID19 in patients with potentially resectable periampullary tumours. Method(s): Observational study, limited to the year 2021, on the management of OI in periampullary pathology. Analysis of the different biliary drainage (BD) techniques (endoscopic/transhepatic) and the associated complications. The indication criteria for BD were: bilirubin levels >10 mg/dl, cholangitis or expectation of surgery >2 weeks from inclusion on the waiting list. Patients with criteria of unresectability or those with neoadjuvant indication were excluded from the study. Result(s): Thirty-five patients were analyzed, with an age range between 45-80 years, who were indicated to undergo a pancreaticoduodenectomy. 51% of these patients required preoperative DB. DB was performed endoscopically (ERCP) in 10 patients and by transparietohepatic approach (TPHD) in 8 patients. In endoscopic approach the majority of stents used were expandable coated metallic (eight patients). The most frequent complications associated with ERCP were cholangitis and acute cholecystitis. The most frequent complication associated with TPHD was cholangitis. Conclusion(s): Preoperative BD associates a greater number of perioperative complications. At present, there is consensus in avoiding preoperative DB, except in cases with cholangitis or hyperbilirubinemia. If DB is necessary, the endoscopic approach (ERCP) would be indicated. Coated Metal stents should be considered for patients with resectable pancreatic cancer, especially if surgery is not immediate.

Management of acute cholecystitis during the Covid-19 pandemic - A complete cycle

Background: Acute cholecystitis is a common surgical emergency. NICE guidelines recommend early laparoscopic cholecystectomy should be performed within 1 week of diagnosis. Emergency and elective surgical provision was affected during the first wave of the covid pandemic due to high postoperative mortality and pulmonary complications. The objectives of this audit were to assess and improve the local management of acute cholecystitis during the Covid-19 pandemic. Method(s): A retrospective review of all patients who presented with acute cholecystitis over 2 months was performed in April 2020. Several interventions were introduced following the first cycle to improve our adherence with NICE guidelines, including 'green elective surgical pathway', clinical priority coding for elective surgeries, a hot gallbladder pathway, and a dedicated weekend and evening list. A re-audit was performed over 2 months in July 2020. These findings were presented at the departmental meeting. Result(s): 34 patients were reviewed in the first audit and 37 in the re-audit. A higher number of patients with acute cholecystitis in cycle 2 had admission covid swabs (97.3% vs 64.7%) and interval covid swabs (54.1% vs 0%) compared to cycle 1. One patient was tested positive for Covid-19 in cycle 2 and was listed for elective operation. Cycle 2 revealed a higher rate of hot gallbladder (from 8.8% to 10.8%) and a shorter median length from admission to operation (from 4 to 1.5 days). A higher rate of patients was readmitted due to complications of cholecystitis in cycle 2 (29.7% vs 20.6%) compared to cycle 1. Conclusion(s): The overall performance is still behind the NICE guideline recommendation. We have identified factors such as pressure on theatre facilities and resources and cancer fast-track priority surgeries during the Covid-19 pandemic. Ongoing audit and optimisation of the hot gallbladder pathway, elective surgical pathway, extra lists, and clinical priority of operations are important to improve the quality of care for patients with acute cholecystitis.

A review of emergency laparoscopic cholecystectomies during the COVID-19 pandemic compared to pre-pandemic. Is there a difference in patient and financial outcomes?

Background: The COVID-19 pandemic was declared the greatest challenge the NHS would face since its creation. As a means of combatting the unprecedented strains COVID-19 was expected to force upon hospitals and their staff, NHS England sanctioned the postponement of all non-urgent elective surgery during the first wave of the COVID-19 pandemic. Approximately 70 000 cholecystectomies are performed every year in the UK, with the vast majority of these being elective laparoscopic cholecystectomies (LC). However, in the early stages of the pandemic, both national and international surgical bodies warned of the potential risks of aerosol virus transmission with the use of laparoscopy. Therefore, conservative management for emergency general surgical pathologies was recommended where possible. Delays in performing LC are associated with recurrent cholecystitis, pancreatitis and cholangitis;all of which present as emergencies with significant associated morbidity and mortality. This in turn has an economic impact on the NHS. We aimed to evaluate if patients undergoing emergency LC during the COVID-19 pandemic at our site, had different outcomes compared to those treated prior to the pandemic. Has the COVID-19 pandemic negatively impacted their patient journey? Furthermore, has the pandemic led to increased costs for our site? Methods: A retrospective data collection was performed to identify all patients who had an emergency LC from March 2019 - March 2021. Patients were subsequently categorised into 'pre-COVID-19' and 'during COVID-19' groups. Hospital computer systems were used to review operative admission length of stay (LoS), rate of conversion to open surgery/subtotal cholecystectomy, operative time, post-operative complications/return to theatre and readmission rate. Histopathology reports were analyzed to assess if the 'during COVID-19' cohort had a higher rate of complicated cholecystitis. Finally costs of the operative admission and associated admissions (pre and post-operatively), as well as the tariff for investigations performed for gallstone disease were calculated for each cohort of patients. Result(s): 158 patients were included in the study. A 42% reduction in emergency LC cases was observed during the COVID-19 pandemic compared to pre-pandemic. No statistically significant differences were seen between the two groups when reviewing the rate of conversion to open surgery or the incidence of post-operative complications/need to return to theatre. The rate of subtotal cholecystectomy was higher in the 'during COVID-19' group (12% vs. 3%) and this was found to be statistically significant (p-value 0.024). Operating times were longer during the pandemic (93 vs. 80 mins), as was the LoS for the operative admission (5 vs. 6 days), however these results were not statistically significant. Interestingly, same day emergency care (SDEC) reviews were more frequent in the 'during COVID-19' group (13.1 vs. 29.3%) and this was statistically significant (p-value 0.015). There was no statistically significant difference between the groups in relation to histopathology results. The most prevalent histopathology of both cohorts was chronic cholecystitis (58 vs. 48.28%). Acute on chronic cholecystitis (23 vs. 25.86%) and necrotising/gangranous changes (11 vs. 12.07%) were more prevalent in the 'during COVID-19' group. When reviewing costs between the two groups, no statistically significant differences in LoS, nor investigation tariffs was observed. Conclusion(s): Our study shows that the COVID-19 pandemic has had a negative impact on two clinical aspects of emergency LC - an increase in the rate of subtotal cholecystectomy, as well as SDEC reviews. This could be explained by delays in elective surgery encountered during the pandemic, leading to patients experiencing recurrent infections, or other associated complications of gallstone disease and consequently requiring more frequent clinician/SDEC reviews. These complications can also result in unclear anatomy, diffuse scarring, necrosis and abscess formation, all of which n lead to increasingly complex cases encountered intra-operatively. If surgeons are unable to safely achieve a critical view of safety, guidance recommends subtotal cholecystectomy as a bail out procedure, in order to avoid serious damage to the bile duct or blood vessels. This could justify the statistically significant higher rate of subtotal cholecystectomy in the 'during COVID-19' group. Currently, there are approximately 6 million patients on NHS surgical waiting lists and this issue must be addressed urgently in the COVID-19 recovery phase, so as to prevent adverse outcomes for both patients and the NHS.
