SP9.7 - Emergency vs. elective biliary admissions in the elderly on a unit adopting index admission cholecystectomy and bile duct exploration. Patients over 70 years with biliary emergencies have more acute cholecystitis and empyema and need signific

Abstract Aim To compare operative and postoperative outcomes of benign biliary surgery in elderly patients. Methods A prospective database of cholecystectomies and bile duct explorations was analysed, comparing index admission surgery for biliary emergencies (Group I, 559, 63.2%) to elective surgery (Group II, 325, 36.8%) in the over 70.

Conclusions In spite of increased difficulty and higher incidence of bile duct exploration more emergencies than electives resolve in one episode. Other outcomes compare favourably with elective surgery. Index admission surgery is justified in the elderly.
