Comparison of outcomes of single-incision and conventional laparoscopic cholecystectomy for cholecystitis requiring percutaneous transhepatic gallbladder drainage

Introduction Single-incision laparoscopic cholecystectomy (SILC) has been accepted as a less invasive alternative to conventional laparoscopic cholecystectomy (CLC). However, the feasibility and safety of SILC for acute cholecystitis, especially in cases with percutaneous transhepatic gallbladder drainage (PTGBD), are still limited because of the technical difficulty of SILC. The aim of this study was to retrospectively evaluate the safety and feasibility of SILC compared to CLC for cholecystitis requiring PTGBD. Methods From 1 July 2017 to 8 June 2019, eight patients underwent SILC with PTGBD, and nine underwent CLC with PTGBD. The patients' data, including the operative time, total blood loss, conversion rate to laparotomy, and perioperative complications, were compared. Results In seven of eight patients, SILC was successfully performed. Only one patient required conversion to open surgery because necrosis prevented the cystic duct from being clipped. However, bile leakage occurred in this patient and was successfully treated with percutaneous drainage and antibiotics. In the CLC group, one patient required laparotomy but had no postoperative complications due to strong adhesion. One patient underwent reoperation for bile duct injury after the first operation. One other complication (ie, wound infection) was seen in the CLC group. There was no significant difference in the mean operative time and estimated blood loss between the SILC and CLC groups. Conclusion With our gallbladder retraction method, SILC may be a relatively safe and feasible alternative to CLC for cholecystitis, even in cases requiring PTGBD.
