First case reported of Bouveret's syndrome associated to duodenal and biliary perforation to retroperitoneum

We present the case of a 69 year old woman with a history of cholecystitis, who consulted for severe abdominal pain, nausea and vomiting. Abdominal CT showed duodenal obstruction caused by a gallstone, cholecystoduodenal fistula and pneumobilia, what is known as Bouveret's syndrome, a rare form of gallstone ileus. Additionally, she presented free duodenal and vesicular perforation to retroperitoneum at the same level of the cholecystoduodenal transit point. The patient underwent a difficult cholecystectomy, enterolithotomy, repair of the duodenal defect, extensive washing and drainage of the retroperitoneum. The postoperative course was uneventful except for a laparotomy infection.

Flexible endoscopic treatment of Zenker's diverticulum: thirteen years' experience in Spain

Introduction: Flexible endoscopic treatment is one of the alternative approaches for the management of Zenker's diverticum. The present paper shows our short-term and long-term results with flexible endoscopic cricopharyngeal myotomy/septotomy. Patients and methods: A retrospective analysis of our experience in patients with Zenker's diverticulum treated using a flexible endoscope, assisted by a flexible diverticuloscope, between 2002 and 2015. Myotomy/septotomy was performed with a needle-knife papillotome under deep sedation or general anesthesia. Results: Among the 64 patients treated, two died within 10 days of surgery from causes not directly related to the procedure, and one presented with pharyngo-esophageal perforation, which recovered with conservative management at 47 days after admission. Four additional patients were lost to short-term follow-up. Among the 57 remaining patients, 52 had complete relief of dysphagia after 6 weeks. Eleven of these had recurrent symptoms on the mid and the long term. Eight were retreated with the same flexible endoscopic technique, one with a hybrid endoscopic approach, one with classical open surgery and one refused retreatment. After a mean follow-up of 2 years and a half, 33 of 37 patients reported absent or minimal dysphagia, controllable with punctual dietary restrictions. Conclusions: Flexible endoscopic treatment for Zenker's diverticulum is effective and safe. It represents an option on an equal footing to rigid endoscopy and classical open surgery and may also be used when the latter two are technically impracticable or contraindicated.
