Gastric bezoar after Vertical Banded Gastroplasty: A Case Report and Review of the Literature

引用

Surgical Science 2011年第5期2卷 242-245页

作者： Abdul S. Bangura Stelin Johnson Karen E. Gibbs 不详

Gastric bezoars are uncommon in the bariatric surgery population. Though popular in earlier decades, the Vertical Banded Gastroplasty (VBG) is no longer a staple procedure in the United States. It has been supplanted by the Roux-en-Y gastric bypass (RYGBP) and the laparoscopic adjustable gastric band (LAGB) as the most commonly performed bariatric procedures. However, there are many patients who have previously undergone VBGs, and may present with associated complications. We present a case of a gastric obstruction caused by a bezoar in a patient who had a VBG fifteen years prior to presentation.

Esophageal obstruction due to enteral feed bezoar:A case report and literature review

World Journal of Gastrointestinal Endoscopy 2010年第10期2卷 352-356页

This paper describes a rare complication of enteral feeding,esophageal obstruction due to feeding formula bezoar,and reviews the published cases. An attempt to re-insert the nasogastric tube in a chronically ventilated 80-year-old female fed via a nasogastric tube with Jevity failed. An esophagogastroduodenoscopy revealed an 18 cm-long concretion of the feeding formula,fi-lling most of the esophageal lumen,which was removed endo scopically. Forty-two cases of feeding formula esophageal bezoars have been reported in the literature. The formation of feeding formula bezoars is triggered by acidic gastroesophageal reflux. The acidic pH in the esophagus causes clotting of the casein in the formula. Predisposing factors for bezoar formation are:mechanical ventilation,supine position,neurological diseases,diabetes mellitus,hypothyroidism,obesity and history of partial gastrectomy. Diagnosis and removal of the bezoar is done endoscopically. Feeding in a semi-recumbent position,administration of prokinetic agents and proton pump inhibitors may prevent this complication.

bezoars are accumulations of human or plant fiber located in the gastrointestinal tract of both humans and animals. Patients remain asymptomatic for several years, and the symptoms develop as these accumulations increase in size to the point of obstruction or perforation. We report the case of a 21-year-old patient at 10 d postpartum, who presented with acute abdomen associated with sepsis. Given the urgency of the clinical picture, at no point was the presence of a giant bezoar at gastric level suspected, specifically a trichobezoar. The emergency abdominal and pelvic ultrasound revealed only unspecific signs of perforated hollow viscus. Diagnosis was therefore made intraoperatively. A complete gastric trichobezoar was found with gastric perforation and secondary peritonitis. The peritoneal fluid culture revealed Candida glabrata.
