Endoscopic management of giant gastric dilatation in an anorexia nervosa patient after binge eating

Acute gastric dilatation is a rare and potentially life-threatening condition that may occur in patients suffering from anorexia nervosa after ingesting large amounts of food within a short period. Frequently, this condition is considered a surgical emergency due to subsequent occurrence of complications such as gastric necrosis or perforation.Here we report a case of a young female patient (23 years) with anorexia nervosa who presented with severe abdominal pain, nausea, and inability to vomit after a period of binge eating. Abdominal computed tomography revealed an extremely dilated stomach measuring 39.0 cm × 18.0 cm in size. Initial nasal decompression therapy using gastric tubes had failed. Due to the absence of complications, it was decided to treat her solely by endoscopic means under mechanical ventilation. After undergoing multiple overtube-assisted esophagogastroduodenoscopies (EGDs), she fully recovered eventually.This case demonstrates that interventional endoscopic treatment of a patient with uncomplicated acute gastric dilatation is feasible and safe, at least under general anesthesia. Hence, this option should be considered when sole gastric tube suction fails, and there is no indication of complications such as peritonitis, sepsis, perforation, or gastric ischemia. A more invasive and aggressive surgical procedure may be avoided in selected cases, and the length of hospital stay may be shortened.

Gastric volvulus is a rare and life-threatening abdominal pain

Gastric volvulus is a rare and life-threatening abdominal pain condition resulting from the stomach twisting on its own longitudinal (organo-axial) or transverse (mesentero-axial) axis. Gastric volvulus can be primary or secondary. Secondary is most commonly related to para-esophageal hernia. Gastric volvulus can have an acute or chronic presentation, the acute form presents abdominal pain with a risk of gastric ischemia with subsequent perforation. Diagnosis is made by imaging studies such as barium contrast studies in the upper digestive tract or abdominal and chest computed tomography (CT). CT of the abdomen and thorax is very useful in the diagnosis as it can demonstrate the abnormal position and gastric torsion The goal in the definitive treatment of gastric volvulus is resolution of gastric obstruction and prevention of recurrence. Performing volvulus reduction, repair of the concomitant cause (para-esophageal hernia), fundoplication and/or gastropexy to the anterior abdominal wall. Gastropexy is considered safe and effective in elderly patients with high surgical risk.

Case report: gastric ischemia, a fatal disease of gastric pneumatosis

Background Gastric pneumatosis indicates the presence of air within the stomach wall. The etiologies included gastric ischemia, gastric intramural infection, gastric mucosal disruption, and secondary to pneumomediastinum. Gastric ischemia is rare because of the rich collateral blood supply to the stomach. Case presentation An 82-year-old man presented to the emergency department with a 2-day history of epigastric fullness, following by fever and low blood pressure. Chest X-ray and abdominal computed tomography revealed gastric pneumatosis at the gastric fundus. The esophagogastroduodenoscopy confirmed the ischemic change of mucosa at the gastric fundus. After antibiotics and medical management, the patient became better and was eventually discharged. Conclusion For the diagnosis of gastric ischemia, physicians should be alert to the hints of gastric pneumatosis from X-ray and computed tomography. It is important to distinguish between gastric ischemia and the other causes of gastric pneumatosis to judge clinical management.

First Report of Two Cases of Acute Gastric Ischemia after Robot-Assisted Radical Cystectomy

Gastrointestinal ischemia is rare after small pelvis surgery. Minimal invasive robotic surgery requires adaptation of the surgical approach for cystectomy and derivation construction such as the use of pneumoperitoneum and Trendelenburg positioning of the patient. Two cases with gastric ischemic complications after robot-assisted radical cystectomy are described. The first case was a 68-year-old female who had prolonged gastroparalysis and blood in a replaced gastric tube at day 10 after robotic cystectomy and Bricker urinary derivation. Gastroscopy revealed ischemia of gastric and proximal duodenal mucosa while computed tomography showed multiple calcifications and thrombi in the coeliac trunk branches and splenic infarcts. The stenosis of the origin of the mesenteric superior artery was stented via an endovascular procedure, and the patient recovered with normal gastroscopy 1 month postoperatively. The second case was a 73-year-old male who developed abdominal pain and fever 5 days after robotic cystectomy and Bricker. On abdominal computed tomography imaging, subcutaneous emphysema, intra-abdominal air, and calcification at the origin of the coeliac trunk were found. At laparotomy 5 days after the cystectomy, a 3 cm hole in the fundus of the stomach was found which was removed with the major stomach curvature. Gastroscopy 5 days after hemigastrectomy revealed no remnant ischemia. The prolonged pneumoperitoneum during robotic cystectomy, the deep Trendelenburg position, and the preoperatively impaired vascular system can be the reasons of our first two cases of gastric ischemia. This rare complication should be kept in mind in patients with symptoms of gastric ischemia since it can result in gastric perforation.
