Laparoscopic cholecystectomy in the elderly: analysis of pre-operative risk factors and postoperative complications.

A retrospective study was conducted of two groups of patients over (group 1, n = 57) and under (group 2, n = 655) the age of 70 years who underwent laparoscopic cholecystectomy (LC). The pre-operative physical status and systemic complications, operation time, postoperative complications, postoperative hospital stay and other clinical features of the two groups were compared. The incidence of pre-operative complications in group 1 was significantly higher than that in group 2 (P < 0.05). Postoperatively no severe complication was found in any patient. Group 1 showed significantly prolonged operation time and postoperative hospital stay compared with group 2 (P < 0.05). The difference between the groups in the intra-operative treatment time and postoperative treatment is attributed to the greater prevalence of common bile duct stone in group 1 as there was little difference between the groups in the postoperative recovery after exclusion of these patients. No pulmonary complications, which are associated with LC, were observed; the postprocedure pain was slight and the period of bedrest was short. If complications associated with pneumoperitoneum can be prevented, this surgery is an excellent measure to improve the quality of life of even elderly patients with cholecystolithiasis.
