Pseudomembranous colitis in patients with COVID-19 (review)

AIM: to estimate the features of pseudomembranous colitis in patients with COVID-19, diagnostics, conservative treatment and surgery for complications. PATIENTS AND METHODS: a retrospective analysis of 396 patients with pseudomembranous colitis (PMC) in patients with new coronavirus infection was carried out for the period from March 2020 to November 2021. Among them there were 156 (39.3%) males, females - 240 (60.6%), moderate and severe forms of COVID-19 occurred in 97.48%. The diagnosis of PMC was established due to clinical picture, laboratory, instrumental methods (feces on Cl. difficile, colonoscopy, CT, US, laparoscopy). RESULT(S): the PMC rate in COVID-19 was 1.17%. All patients received antibiotics, 2 or 3 antibiotics - 44.6%, glu-cocorticoids were received by all patients. At 82.8%, PMC developed during the peak of COVID-19. To clarify the PMC, CT was performed in 33.8% of patients, colonoscopy - 33.08%, laparoscopy - in 37.1% (to exclude bowel perforation, peritonitis). Conservative treatment was effective in 88.8%, 76 (19.1%) patients had indications for surgery (perforation, peritonitis, toxic megacolon). Most often, with peritonitis without clear intraoperative confir-mation of perforation, laparoscopic lavage of the abdominal cavity was performed (60 patients - 78.9%, mortality - 15.0%), colon resection (n = 6 (7.9%), mortality - 66.6%), ileo-or colostomy (n = 8 (10.5%), mortality - 37.5%), colectomy (n = 2 (2.6%), mortality - 50.0%). The overall postoperative mortality rate was 22.4%, the incidence of surgical complications was 43.4%. In addition, in the postoperative period, pneumonia was in 76.3%, thrombosis and pulmonary embolism in 22.3% of patients. In general, the overall mortality in our patients with PMC was 11.4%, with conservative treatment - 8.8%. CONCLUSION(S): pseudomembranous colitis is a severe, life-threatening complication of COVID-19. In the overwhelm-ing majority of patients, conservative therapy was effective, but almost 1/5 of patients developed indications for surgery, the latter being accompanied by high mortality and a high morbidity rate. Progress in the treatment of PMC, apparently, is associated with early diagnosis, intensive conservative therapy, and in the case of indications for surgery, their implementation before decompensation of the patient's condition and the development of severe intra-abdominal complications and sepsis.Copyright © 2022, Association of Coloproctologists of Russia.

A Case Report of Iatrogenic Esophageal Perforation: Complication of Orogastric Tube Placement

Introduction: Orogastric tube insertion is a routine procedure in medical care. However, misplacement of the tube can cause a variety of complications, which can be life threatening in some instances. Case Description/Methods: 71-year-old male presented with dyspnea, fever, chills, cough, and myalgia for 2 weeks. He had tachycardia, tachypnea, and was hypoxic to 66% in room air. He was found to have acute hypoxic respiratory failure secondary to COVID-19 Pneumonia and was admitted to ICU. But, he continued to be hypoxic and was started on BiPAP. He eventually became altered, and was intubated. Post intubation orogastric tube (OGT) placement was unsuccessful on the first attempt due to resistance. On the second attempt, the nurse was able to advance partially (Figure). But, a chest XR showed OGT in the mediastinum, and OGT was removed. CT of neck and chest revealed pneumomediastinum with possible mid-thoracic esophageal perforation. The patient was started on broad-spectrum antibiotics and thoracic surgery was consulted. Given his mechanical ventilation requirement, surgery deemed him unfit to tolerate thoracotomy and the endoscopic procedure was not available in the hospital. So, recommendation was to manage conservatively. His hospital course was complicated by hypotension requiring vasopressors and metabolic acidosis in setting of acute renal failure requiring CRRT. Code status was changed by the family to Do Not Resuscitate due to his deteriorating condition. Eventually, he had a PEA arrest and was expired. Discussion(s): OGT intubation is performed at hospitals for feeding, medication administration or gastric decompression. Although it is considered a safe procedure, complications can arise due to OGT misplacement or trauma caused by the OGT itself or the intubation process. OGT misplacement is typically endotracheal or intracranial. Misplacement within the upper GI lumen is usually detected by a kink in the oropharynx or esophagus. The subsequent complications are identified by the structure that is perforated (e.g., mediastinitis or pneumothorax). Regardless of whether counteraction is perceived, the physician must be careful not to apply excessive force. The location of the OGT tip should be determined by a chest radiograph;visualization of the tip below the diaphragm verifies appropriate placement. Complications of OGT insertion are uncommon;however, the consequences are potentially serious, and the anatomy of the upper GI tract should be understood by all who are involved in the care.

Spontaneous Gastro-pancreatic Fistula: A Rare Complication of Acute Pancreatitis

Introduction: Although Gastrointestinal fistula is a well-recognized complication of acute pancreatitis, it has been rarely reported. Here we present a rare case of spontaneous gastro-pancreatic fistula following acute pancreatitis. Case Description/Methods: 42 y/o female with PMH of SLE with a recent prolonged hospitalization for acute drug-induced pancreatitis with pseudocyst came to ED with fever, abdominal pain, nausea, and vomiting. She was tachycardic, had leukocytosis, and was positive for COVID-19. CT Scan A/P showed multiple infected peripancreatic collections with communication of the left upper quadrant collection with the gastric lumen (Figure). The patient was hospitalized, Kept NPO, and started on fluids and antibiotics. IR evaluated and put 2 pigtail catheters for drainage of peripancreatic collections. The tip of the pigtail catheter in the left peripancreatic/retroperitoneal collection was in the gastric lumen. The surgery team recommended continuing with conservative treatment with parenteral nutrition, and IV antibiotics as the patient were nontoxic with no signs of free perforation, and pancreatitis would more likely erode a staple or suture line and would put the patient at further risk of free perforation if repair attempted. IR was successful in pulling the drain out of the gastric lumen on the second attempt to allow gastric perforation to heal. Antibiotics were upgraded as per the culture and sensitivity results of the drain fluid. Repeated multiple bedside leak tests and CT scans with oral contrast continue to be positive for patent gastro-pancreatic fistula. Pigtails catheter continues to drain significant necrotic collection. The patient continues to be hospitalized and is being managed conservatively with Parenteral nutrition, and IV antibiotics. Discussion(s): Fistula of the GI tract following acute pancreatitis can be caused by multiple reasons. Necrosis of the bowel may occur concomitantly with the pancreatic or peripancreatic tissue. Furthermore, enzyme-rich fluid and necrosis can lead to vascular thrombosis, which compromises the blood supply of the segmental GI tract, eventually leading to bowel necrosis. GI fistulas are more common in patients with necrotizing pancreatitis with infected pancreatic necrosis. Despite pharmacologic suppression of pancreatic exocrine secretion and advances in endoscopic and percutaneous therapeutic techniques, pancreatic fistula continues to be a source of morbidity and mortality following pancreatitis and requires multidisciplinary treatment.

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.

A Rare Manifestation of Unknown Hyperparathyroidism as a Perforated Peptic Ulcer.

Hypercalcemia is a common electrolyte abnormality with different causes. Hypercalcemia is most often associated with malignancy and primary hyperparathyroidism and malignancy together account for most cases. Primary hyperparathyroidism manifests as hypercalcemia owing to the overproduction of parathyroid hormone. In most cases, primary hyperparathyroidism manifests due to a solitary parathyroid adenoma. Based on calcium levels, hypercalcemia can be classified as mild, moderate, and severe. Hypercalcemia typically presents with non-specific clinical features. Here, we present the case of a 38-year-old male patient who presented to the emergency department (ED) with acute abdominal pain and a tender abdomen with absent bowel sounds. He had chest radiography and blood tests initially. Chest radiography showed left-sided pneumoperitoneum, and the patient was suspected to have a perforated peptic ulcer due to hypercalcemia secondary to a parathyroid adenoma during the second wave of the coronavirus disease 2019 (COVID-19) pandemic. The findings were confirmed by a computerized tomography scan of the abdomen, and the patient was treated with intravenous fluids for hypercalcemia and was managed conservatively for a sealed perforated peptic ulcer following discussion in the multi-disciplinary team meeting (MDT). The COVID-19 pandemic led to a long waiting list and delays in the timely management of patients requiring elective surgical intervention, such as parathyroidectomy. The patient made a complete recovery and had parathyroidectomy of the inferior right lobe two months later.

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.

Diaphragmatic Rupture and Gastric Perforation in a Patient with COVID-19 Pneumonia.

We describe the case of a young female patient admitted to our emergency department during the Italian COVID-19 epidemic, for fever and dry cough associated with symptoms of gastric reflux over the previous 5 days. Lung ultrasound showed diffuse bilateral B lines with irregular pleural thickening, and consolidation with air bronchogram and slight pleural effusion in the lower left lobe. Chest HRCT and abdominal CT scanning with contrast revealed diaphragmatic rupture with gastric perforation, and atelectasis of the left pulmonary lobe with unilateral pleural effusion, diffuse ground-glass opacities and multiple small consolidations in both lobes. A nasopharyngeal swab for 2019-nCoV was positive. A diagnosis of diaphragmatic rupture and gastric perforation in COVID-19 pneumonia was made. The patient was immediately hospitalized and surgically treated. Treatment for COVID-19 and empiric antibiotic therapy were promptly started. LEARNING POINTS: Coronavirus disease (COVID-19) can cause fever, dry cough and acute respiratory failure.Cough can result in several complications, including rupture of the diaphragm and abdominal herniation.CT scanning is the gold standard technique to investigate COVID-19 pneumonia and diaphragmatic rupture.

Unpredictability of SARS-CoV-2: Pneumoperitoneum a rare complication.

COVID-19 is a viral disease caused by a novel coronavirus that ignited the ongoing pandemic in December 2019. The infected patients may be asymptomatic, have fever and myalgias, develop mild pulmonary symptoms or go into overt respiratory failure. There is also a significant number of patients with gastrointestinal and thromboembolic disease presentation and complications. Since respiratory features predominate, physicians might miss other systemic manifestations. Here, we present the case of a 62-year-old male who was admitted with COVID-19 pneumonia and later went into septic shock and then developed acute abdomen caused by small gut perforation.

Extrapulmonary COVID-19 Presents As Spontaneous Small Bowel Perforation.

SARS-CoV2 is a well-recognized pathogen with a myriad of presenting symptoms. Well-documented pulmonary, neurological, gastrointestinal, and hematologic complications have occurred during the global COVID-19 pandemic. While gastrointestinal symptoms are the most commonly reported extrapulmonary symptom of COVID-19, the incidence of primary perforation has not been widely reported. In this case report, we describe a spontaneous small bowel perforation in a patient who was incidentally found to be COVID-19 positive. This peculiar case underlies the continued evolution of SARS-CoV2 understanding and potential unknown complications of the virus.

Finding an Answer for an Adolescent with Back Pain

Case report - Introduction: This is the case of an adolescent referred to rheumatology following 5 years of back pain. After years of trying a number of treatments without much success, the cause was found to be a previously undiagnosed urological pathology. The case highlights awareness of non-rheumatological causes and incidental findings which can redirect a patient towards more appropriate treatment and reduce the potential for long-term adverse health issues and anxiety. Case report - Case description: B was referred age 16 to rheumatology with a 5-year history of lower back pain. She had previously seen paediatricians with symptoms initially attributed to constipation due to intermittent straining and hard stool. However, constipation remedies had not relieved the pain which progressed gradually to a more persistent dull ache with impact on daily activities. Various analgesics (including paracetamol and non-steroidal anti-inflammatories), exercises and acupuncture had not helped. There was no history of recurrent urinary tract infections or symptom correlation with fluid intake, menstruation or bowel habit. No inflammatory features or connective tissue disease symptoms were noted and family history was unremarkable Clinical examination was normal apart from mild tenderness in the lumbar region. Rheumatoid factor was borderline positive (15 iu/mL) with the rest of blood tests normal including renal function, inflammatory markers (CRP, ESR), anti CCP and ANA. She had minimal microscopic haematuria without proteinuria. MRI spine in 2015 was normal. In view of her young age and symptoms affecting daily activities, STIR sequence spinal MRI was requested. This excluded any new or old inflammatory changes but incidentally identified a dilated left pelvi-calyceal system. Renal ultrasound confirmed a grossly hydronephrotic left kidney with hydroureter and minimal renal tissue suggesting longstanding obstruction. No calculi were seen. The patient was referred to urologists. Further investigations (including MRI abdomen) confirmed similar findings and a distal ureteric stricture. A MAG 3 renogram showed a normal right kidney but only 12% functioning of the left kidney. Urologists have advised surgery (removal of left kidney and ureter) which may relieve symptoms or a conservative non-surgical approach (continue analgesia, physiotherapy and monitoring). The patient and her family are relieved to have a possible cause identified and are considering the surgical option due to ongoing flank discomfort. Case report - Discussion: This was an interesting finding of hydroureter and hydronephrosis causing longstanding back pain presenting to rheumatologists. Until completion of the spondyloarthropathy protocol MRI (STIR images), aetiology had been unclear. Hydronephrosis and hydroureter has no specific age or racial predilection. Signs and symptoms may depend on whether obstruction is acute/chronic. Chronic cases may be asymptomatic or present as a dull discomfort (like this case). Some cases may only present in adulthood with pain precipitated by fluid intake. Blood tests may show impaired kidney function. Post-mortem studies suggest 50% of people have at least one renal abnormality (e.g., renal cysts, duplex ureters) with autopsy series incidence of hydronephrosis reported as 3.1%. Causes include anatomical abnormalities such as vesico-ureteric reflux, urethral strictures (usually present in childhood), calculi, benign prostatic hyperplasia, or intrapelvic neoplasms, pregnancy and infections (e.g., TB). Sudden onset unilateral renomegaly was reported in one case of primary Sjogren's with lymphocytic interstitial nephritis and positive Sjogren's autoantibodies. Our patient has no clinical or serological evidence of connective tissue disease. Minor pelvi-calyceal distension can occur as a normal finding in wellhydrated patients and pregnancy. However, significant hydronephrosis requires assessment to determine cause as it may affect long term renal function. Imaging via computed tomography, ultrasound and urograms can help guide further management. In this case the preceding cause and duration of pathology is unknown. Sterile, giant hydronephrosis treatment options include observation and ureteric stent or nephrostomy in patients unfit for surgery. Nephrectomy is advised for pain and recurrent infection in a non-functioning kidney. Complications may include bowel perforation, vascular injury and urine leakage. Both open and minimally invasive procedures have good reported outcomes. The COVID-19 pandemic and exams have affected timing of any elective procedures and the patient understands surgery may or may not offer complete symptom resolution. Case report - Key learning points: . Non-inflammatory causes of back pain should always be considered in cases of persistent back pain, particularly in young people to ascertain if there is a treatable cause . Hydronephrosis cases can be asymptomatic or present with vague, intermittent, non-specific abdominal symptoms with normal physical examination with or without haematuria. This can cause diagnostic uncertainty and delay referral to urology and appropriate renal investigations . Assessment of renal function (including MAG 3 renogram) is important to guide further management . Surgical interventions (pyeloplasty/nephrectomy) may ease symptoms long term but there is no guarantee of a successful outcome and operative risks need to be considered too . Left undiagnosed, potentially this patient could have had further disruption to daily activities and both physical and mental well being.

A Study of Perforative Peritonitis in a Period of One Year during Covid-19 Pandemic at a Medical College in Rajasthan

Hollow viscous perforation is one of the most common emergency dealt by general surgeons worldwide. A high degree of suspicion is required and prompt management is warranted to reduce morbidity and mortality. Here we present a study of perforative peritonitis in our medical college at the outskirt of Udaipur city in the state of Rajasthan, India during the Covid-19 pandemic. During the one year study period from September 2020 to August 2021, a total of 16 cases of hollow viscous perforation admitted and treated. The number is relatively low because of the pandemic and there was a period of total lockdown with negligible patient footfall. All patient had free gas under diaphragm in plain x-ray and all of them were scheduled for emergency laparotomy after adequate resuscitation. Emphasis given on the location of perforation, etiology, organism on culture of peritoneal fluid and procedure undertaken. Copyright © 2022, Dr Yashwant Research Labs Pvt Ltd. All rights reserved.
