Two cases of intestinal perforation due to mesenteric artery embolism during extracorporeal membrane oxygenation and intra-aortic balloon pumping.

The patient in case 1 was a 50-year-old man who presented to the emergency department of the local hospital with chest pain and syncope for 3 hours due to acute myocardial infarction. He underwent cardiopulmonary resuscitation (CPR) followed by extracorporeal membrane oxygenation (ECMO), and intestinal perforation was detected on day 9. The patient in case 2 was a 58-year-old man who was admitted to the hospital with abdominal pain lasting for 3 days. He also required CPR and ECMO for cardiogenic shock, and intestinal perforation was identified on day 7 of ECMO. We believe that this case report will be important to alert clinicians to the possibility of this complication and to encourage early detection and intervention to improve prognosis. Conventionally, the gastrointestinal tract has received secondary attention in patients receiving ECMO support because the vital organs tend to be considered first. However, this case report illustrates the importance of monitoring gastrointestinal function in patients undergoing ECMO.

Gastrointestinal complications (gangrene or perforation) after corona virus disease 2019 - A series of ten patients.

During the recent second wave of corona virus disease 2019 (COVID-19) pandemic in India, we managed a series of gastrointestinal complications in patients with COVID-19. We aim to highlight the key presentation and clinical course and emphasize the lessons we learnt from our series of such patients. A case review of ten consecutive patients with either bowel gangrene or perforation who were managed at our centre from March 20, 2021 to June 10, 2021. Clinical-demographic details, possible etiology, radiological findings, management and outcomes have been described. Of the 10 patients, 2 presented with bowel gangrene and 8 with perforation. In our series, all these patients were diagnosed with the help of computed tomography (CT) abdomen during the 3rd week after diagnosis of COVID-19. All had received steroid medication. Both patients with bowel gangrene and 4 of 8 patients with perforation underwent surgery, while 4 were managed non-operatively. Barring one patient, all the operated patients succumbed within 5 days of surgery after rapid clinical deterioration. Non-operative management in selected patients with perforation including placement of percutaneous drains, bowel rest and antibiotics was successful. Emergency surgery for COVID-19 related intestinal gangrene or perforation was associated with high mortality in our series. Non-operative management which avoids the added stress of a major emergency surgery particularly in patients just recovering from COVID-19 may be considered in stable patients in whom perforation appears to be contained.

Case Report: Paralytic Ileus: A Potential Extrapulmonary Manifestation of Severe COVID-19.

The COVID-19 pandemic has recently spread worldwide, presenting primarily in the form of pneumonia or other respiratory disease. In addition, gastrointestinal manifestations have increasingly been reported as one of the extrapulmonary features of the virus. We report two cases of SARS-CoV-2 infection complicated by paralytic ileus. The first patient was a 33-year-old man who was hospitalized with severe COVID-19 pneumonia requiring ventilator support and intensive care. He developed large bowel dilatation and perforation of the mid-transverse colon, and underwent laparotomy and colonic resection. Histopathology of the resected bowel specimen showed acute inflammation, necrosis, and hemorrhage, supporting a role for COVID-19-induced micro-thrombosis leading to perforation. The second patient was a 33-year-old man who had severe COVID-19 pneumonia, renal failure, and acute pancreatitis. His hospital course was complicated with paralytic ileus, and he improved with conservative management. Both cases were observed to have elevated liver transaminases, which is consistent with other studies. Several authors have postulated that the angiotensin-converting enzyme 2 receptors, the host receptors for COVID-19, that are present on enterocytes in both the small and large bowel might mediate viral entry and resultant inflammation. This is a potential mechanism of paralytic ileus in cases of severe COVID-19 infection. Recognizing paralytic ileus as a possible complication necessitates timely diagnosis and management.
