The mRNA-Based Coronavirus Disease-2019 Vaccine-induced Severe Cardiomyopathy: A Rare Incident.

We are presenting a case of severe dilated cardiomyopathy (DCM) post-mRNA-based coronavirus disease-2019 (COVID-19) vaccine (Pfizer-BioNTech) in a young healthy man. After the second dose of the vaccine, his health rapidly declined, and he developed severe DCM with reduced ejection fraction. Investigations for other causes of DCM were unremarkable. Severe DCM following COVID-19 vaccine injection is a rare but serious condition. It also highlights the importance of close follow-up of pericarditis and perimyocarditis cases post-COVID-19 vaccine and we recommend clinicians have a low threshold for using echocardiography for early diagnosis and management.

A serious but rare complication of laparoscopic adjustable gastric banding: bowel obstruction due to caecal volvulus.

Laparoscopic adjustable gastric banding (LAGB) is a widely performed surgical procedure for the treatment of morbid obesity. LAGB complications have declined since its development in the early 1990s. However, LAGB complications are still occurring and can sometimes be serious and life threatening. These complications are related either to the band or to the access port, such as band slippage or tubing disconnection, retrospectively. We report a rare case of bowel obstruction due to caecal volvulus caused by connecting tube used in LAP-BAND system in a bariatric operation, which obstructed a caecal loop, in a female who had undergone LAGB 2 years previously. Diagnosis of bowel obstruction was established with plain abdominal radiograph appearances. Follow-up abdominal computed tomography findings confirmed the diagnosis of caecal obstruction and revealed the underlying cause for this obstruction. Surgery was performed, and intraoperative examination demonstrated that connecting tube of the LAP-BAND system was a main causative factor. We can hypothesize that bowel obstruction secondary to LAGB operation may become frequently diagnosed as more LAGB operations performed worldwide. The emergence of many problems, such as this, can be minimized with enhancement in the development of better surgical materials, proper operative technique, and close postoperative management and follow-up.
