Nondrainage after Laparoscopic Cholecystectomy for Acute Calculous Cholecystitis Does Not Increase the Postoperative Morbidity.

BACKGROUND

It is now established that prophylactic drainage is not needed after laparoscopic cholecystectomy (LC) for chronic calculous cholecystitis. However, the benefit of drains versus their potential harm for acute calculous cholecystitis (ACC) following laparoscopic LC has been questioned. Therefore, we conducted a comparative study to assess the need for drainage.

METHODS

Between January 2014 and October 2016, 212 patients with ACC undergoing LC undergo either drainage (n= 106) or no drainage (n= 106). The primary end points were the number of patients with postoperative drain-related complications, early and late Visual Analogue Scale (VAS) score, and hospital stay. Secondary end points included estimated blood loss, postoperative recovery, analgesia requirement, and cosmetic satisfaction result.

RESULTS

There was no bile duct injury and mortality in both groups. The overall complication rate was 12.5% with no significant difference between those with or without drainage (P=0.16). Normal activity resumption was significantly faster and the postoperative hospital stay was slightly shorter in the nondrainage group (P =0.03 and P= 0.04, respectively). The early VAS score in the drainage group was significantly higher (p< 0.05). There were no significant differences between the two groups in postoperative hematology test, late VAS score, and patient satisfaction of cosmetic outcome.

CONCLUSION

Routine drainage for patients with ACC after LC may not be justified with similar drain-related complications compared with nondrainage group.
