Background And Aims:
The feasibility of incidental cholecystectomy during colorectal cancer (CRC) surgery has not been determined as yet. We aimed to investigate the feasibility of incidental cholecystectomy during CRC surgery.
Methods:
The clinicopathologic data of patients who underwent CRC surgery between January 2004 and May 2011 were assessed. Patients with asymptomatic cholelithiasis were divided into groups that did and did not undergo incidental cholecystectomy. Their in-hospital morbidity and long-term biliary complications were compared.
Results:
Of the 282 patients identified, 143 (50.7%) underwent incidental cholecystectomy and 139 (49.3%) were observed without cholecystectomy. The two groups were similar in clinical characteristics, except for gender and operation time. Only one patient (0.7%) in the cholecystectomy group experienced an intraoperative biliary complication. There was no significant difference in overall in-hospital morbidity between the two groups. After a median follow-up period of 33 months, long-term biliary complications developed in 12 patients (8.6%) in the observation group, with 9 undergoing cholecystectomy.
Conclusions:
Incidental cholecystectomy was not associated with increased postoperative morbidity, whereas previously asymptomatic patients were at substantial long-term risk of becoming symptomatic. Thus, in the absence of clear contraindications, concomitant cholecystectomy might be a desirable treatment option during CRC surgery in patients with asymptomatic gallstones.
