Ischemic Necrosis of the Gastric Remnant without Splenic Infarction Following Subtotal Gastrectomy

Gastric remnant necrosis after a subtotal gastrectomy is an extremely uncommon complication due to the rich vascular supply of the stomach. Despite its rareness, it must be carefully addressed considering the significant mortality rate associated with this condition. Patients vulnerable to ischemic vascular disease in particular need closer attention and should be treated more cautiously. When gastric remnant necrosis is suspected, an urgent endoscopic examination must be performed. We report a case of gastric remnant necrosis following a subtotal gastrectomy and discuss possible risk factors associated with this complication.

Pneumoretroperitoneum, Pneumomediastinum, Pneumothorax, and Subcutaneous Emphysema after Diagnostic Colonoscopy / 대한소화기학회지

Colonoscopy is a commonly performed endoscopic procedure. Although it is generally considered to be safe, serious complications, such as colorectal perforation, can occur. Most colonic perforations are intraperitoneal and cause pneumoperitoneum with acute abdominal pain as the initial symptom. However, extraperitoneal perforations with pneumoretroperitoneum may happen, albeit rarely, with atypical initial symptoms. We report a rare case of rectosigmoid perforation occurring after diagnostic colonoscopy that developed into pneumoretroperitoneum, pneumomediastinum, pneumothorax, and subcutaneous emphysema, with a change in voice and neck swelling as the initial symptoms. The patient was successfully treated with endoscopic closure of the perforation and conservative management.
