Prophylactic Cholecystectomy is Safe in Patients Undergoing Cytoreductive Surgery With Hyperthermic Intraperitoneal Chemotherapy.

BACKGROUND

While cholecystectomy is one of the most common operations performed in the United States, there is a continued debate regarding its prophylactic role in elective surgery. Particularly among patients with peritoneal carcinomatosis who undergo cytoreduction surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC), further abdominal operations may pose increasing morbidity due to intraabdominal adhesions and potential recurrence. This bi-institutional retrospective study aims to assess postoperative morbidity associated with prophylactic cholecystectomy at the time of CRS-HIPEC.

METHODS

We performed a bi-institutional retrospective analysis of 578 patients who underwent CRS-HIPEC from 2011 to 2021. Postoperative outcomes among patients who underwent prophylactic cholecystectomy at the time of CRS-HIPEC were compared to patients who did not, particularly rate of bile leak, hospital length of stay, rate of Clavien-Dindo classification morbidity grade III or greater, and number of hospital re-admissions within 30 days.

RESULTS

Of the 535 patients available for analysis, 206 patients (38.3%) underwent a prophylactic cholecystectomy. Of the 3 bile leaks (1.5%) that occurred among patients who underwent prophylactic cholecystectomy, all 3 occurred in patients who underwent a concomitant liver resection. There were no significant differences in hospital length of stay, postoperative morbidity, and number of hospital re-admissions among patients who underwent prophylactic cholecystectomy compared to those who did not.

CONCLUSION

Prophylactic cholecystectomy in patients undergoing CRS-HIPEC is not associated with increased morbidity or increased bile leak risk compared to historical data. While the benefits of prophylactic cholecystectomy are not yet elucidated, it may be considered to avoid potential future morbid operations for biliary disease.
