Incidence and risk factors for postoperative common bile duct stones in patients undergoing endoscopic extraction and subsequent cholecystectomy.

BACKGROUND AND AIMS: In patients who undergo cholecystectomy after endoscopic common bile duct (CBD) stone extraction, CBD stones found postoperatively could be problematic. This study aimed to investigate the incidence and risk factors of postoperative CBD stones after cholecystectomy. METHODS: A total of 278 patients (mean age, 59.2 years; 71 men [51.1%]) who underwent endoscopic removal of CBD stones followed by cholecystectomy from January 2013 to December 2017 were included. An endoscopic nasobiliary drainage (ENBD) tube was placed immediately after endoscopic clearance of the CBD stones in all patients until cholecystectomy. An ENBD tubogram was obtained in all patients to determine the presence of postoperative CBD stones. RESULTS: Postoperative CBD stones were detected in 20.1% (56/278). An ENBD tubogram was obtained after an average of 2.42 days postoperatively. Based on univariate analysis, the statistically significant risk factors for postoperative CBD stone were CBD stones >2, CBD stone size >10 mm, cholesterol stone, maximum diameter of CBD >15 mm, treatment with endoscopic sphincterotomy alone, and use of endoscopic mechanical lithotripsy (EML). In multivariate analysis, cholesterol stone, CBD stones >2, CBD stone size >10 mm, and EML were related to postoperative CBD stones after cholecystectomy. CONCLUSIONS: Based on the relatively high rate of postoperative CBD stones after cholecystectomy, careful follow-up should be considered in patients with high-risk factors to detect CBD stones early.

Endoscopic Treatment of Jejunal Heterotopic Gastric Mucosa that Caused Recurrent Intussusception.

Heterotopic gastric mucosa (HGM) is a rare anomaly in the small bowel and may be the cause of intussusception when it gets a lead point in the jejunum. All cases of intussusception due to intestinal HGM have been treated with surgical resection. A 5-year-old girl presented with chief complaints of vomiting and abdominal pain for 2 weeks. A computed tomography scan of the abdomen showed intussusception at the proximal jejunal loops. Three air reductions and one saline reduction were attempted without success. She continued to be symptomatic, and endoscopic evaluation was performed. Enteroscopy revealed some variable-sized polypoid mucosal lesions with erosions on the proximal jejunum. Endoscopic mucosal resection was performed using a snare. The resected tissues histologically showed a hyperplastic polyp arising from the HGM. Her symptoms did not recur within 1 year after the treatment. Our case showed that enteroscopy could be useful for the diagnosis and management of jejunal intussusception caused by HGM.
