Permanent endoscopic gallbladder stenting versus removal of gallbladder drainage, long-term outcomes after management of acute cholecystitis in high-risk surgical patients for cholecystectomy: Multi-center retrospective cohort study.

BACKGROUND

Endoscopic transpapillary gallbladder drainage (EGBD) has been reported as an effective gallbladder drainage treatment option for acute cholecystitis in high-risk surgical patients. However, the long-term outcomes such as cholecystitis' recurrence rate after placement of EGB stenting (EGBS) have not been well studied yet.

AIMS

The aim of the present study was to compare the long-term outcome of EGBS and removal of gallbladder drainage after percutaneous transhepatic gallbladder drainage (PTGBD) or endoscopic nasogallbladder drainage (ENGBD) for acute cholecystitis in high-risk surgical patients and clarify the usefulness of long-term placement of EGBS.

METHODS

We retrospectively studied 180 high-risk surgical patients with acute cholecystitis between January 2010 and December 2018. The patients were divided into two groups: EGBS group (long-term placement of EGBS) or Removal group (removal of drainage tube after PTGBD or ENGBD). Clinical outcomes, including long-term results, were compared between the groups.

RESULTS

The cumulative late adverse event (AE) rates were 5.0% and 22.1% in the EGBS and Removal group (P = .002), with a median follow-up period of 375 and 307 days in the two groups, respectively. The cumulative cholecystitis recurrence rate was 5.0% (2/40) in the EGBS group and 16% (21/131) in the Removal group (P = .024), respectively. In the multivariate analysis for late AE, only EGBS was an independent risk factor with a decreasing value.

CONCLUSION

The permanent EGBS in high-risk surgical patients with acute cholecystitis was considered effective in reducing the risk of late AE.
