ABSTRACT
BACKGROUND: Unrecognized gastric and duodenal peptic ulcer is a common cause of epigastric pains for patients with cholelithiasis qualified for laparoscopic cholecystectomy. Undiagnosed gastric or duodenal ulcer may be the cause of persistent pains after cholecystectomy. The purpose of the study was to assess the value of a routine preoperative panendoscopy for qualifying patients to undergo laparoscopic cholecystectomy. METHODS: The study enrolled 2,800 patients treated for cholelithiasis from May 1993 to December 2002. Endoscopic examination was performed for all treated patients 1 to 4 days before their operations. RESULTS: Preoperative endoscopy showed pathologic changes in the stomach or duodenum in 1,187 (42%) of 2,800 patients qualified for laparoscopic cholecystectomy. Gastric ulcer was found in 179 patients (6.4%) duodenal ulcer in 127 patients (4.5%), gastritis in 735 patients (26.3%), polyps in 143 patients (5.1%), and cancer in 3 patients (0.1%). The surgery was postponed for patients with ulcer, and antiulcer treatment was started. In 16 patients, the symptoms associated with cholelithiasis subsided after healing of the ulcer. Cholelithiasis in these patients was asymptomatic, and a cholecystectomy was not performed. CONCLUSIONS: Panendoscopy should be a routine examination performed for each patient qualified to undergo laparoscopic cholecystectomy. For some patients with asymptomatic cholelithiasis, pain in fact is caused by peptic ulcer.
