Cholecystectomy and ERCP in pregnancy: a nationwide register-based study.

OBJECTIVE

The objective was to examine the outcomes of cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) during pregnancy and compare these outcomes with those in nonpregnant women of fertile age.

SUMMARY BACKGROUND DATA: Although both laparoscopic cholecystectomy and ERCP are considered safe and feasible in pregnant patients, there is still concern and uncertainty regarding gallstone intervention during pregnancy. This study aimed to investigate outcomes in pregnant patients compared to outcomes in nonpregnant patients.

METHODS

Data on all female patients aged 18-45 years were retrieved from the Swedish Registry for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography. The patients were divided into groups according to intervention: cholecystectomy, ERCP, or a combination thereof. Differences between pregnant and nonpregnant patients were analyzed.

RESULTS

A total of 21 328 patients were included, with 291 cholecystectomy and 63 ERCP procedures performed in pregnant patients. At the 30-day follow-up, more complications after cholecystectomy were registered for pregnant patients. However, pregnancy was not a significant risk factor for adverse events when adjusting for previous complicated gallstone disease, intraoperative complications, emergency surgery, and common bile duct stones. There were no differences in outcomes when comparing cholecystectomy among the different trimesters. ERCP had no significant effect on outcomes at the 30-day follow-up.

CONCLUSION

Cholecystectomy, ERCP, and combinations thereof are safe during pregnancy.
