Influence of Percutaneous Transhepatic Gallbladder Aspiration and Drainage for Severe Acute Cholecystitis on the Surgical Outcomes of Subsequent Laparoscopic Cholecystectomy: Post Hoc Analysis of the CSGO-HBP-017 (CSGO-HBP-017C).

OBJECTIVE:Percutaneous transhepatic gallbladder aspiration (PTGBA) and/or drainage (PTGBD) are useful approaches in the management of acute cholecystitis in patients who cannot tolerate surgery because of poor general condition or severe inflammation. However, reports regarding its effect on the surgical outcomes of subsequent laparoscopic cholecystectomy (LC) are sparse. The aim of this retrospective study was to investigate the influence of PTGBA on surgical outcomes of subsequent LC by comparing the only-PTGBA group, including patients who did not need the additional-PTGBD, versus the additional-PTGBD group, including those who needed the additional-PTGBD after PTGBA. PATIENTS AND METHODS:We conducted a post hoc analysis of our multi-institutional data. This study included 63 patients who underwent LC after PTGBA, and we compared the surgical outcomes between the only-PTGBA group (n = 56) and the additional-PTGBD group (n = 7). RESULTS:No postoperative complications occurred among the 63 patients, and the postoperative hospital stay was 11 ± 12 days. Fourteen patients (22.2%) had a recurrence of cholecystitis, of whom 7 patients (11.1%) needed the additional-PTGBD after PTGBA. Significantly longer operative time (245 ± 74 vs 159 ± 65 min, P = 0.0017) and postoperative hospital stay (22 ± 27 vs 10 ± 9 d, P = 0.0118) and greater intraoperative blood loss (279 ± 385 vs 70 ± 208 mL, P = 0.0283) were observed among patients in the additional-PTGBD group compared with the only-PTGBA group, whereas the rates of postoperative complications (Clavien-Dindo grade ≥3: 0% each) and conversion to open surgery (28.6% vs 8.9%, P = 0.1705) were comparable. CONCLUSION:PTGBA for acute cholecystitis could result in good surgical outcomes of subsequent LC, especially regarding postoperative complications. However, we should keep in mind that the additional-PTGBD after PTGBA failure, which sometimes happened, would be associated with increased operative difficulty and longer recovery.
