Preoperative risk factors for technical difficulty in emergent laparoscopic cholecystectomy for acute cholecystitis

We have routinely performed emergent laparoscopic cholecystectomy (LC) as soon as we diagnosed acute cholecystitis (AC), if patients could tolerate surgery. This study was conducted to identify the preoperative risk factors that predict the technical difficulty of emergent LC for AC.

A retrospective review of patients with AC who underwent emergent LC between 2012 and 2019 was conducted. Technical difficulty was defined as the presence of the following conditions: open conversion, operative time ≥120 min, or blood loss ≥500 ml.

In all, 327 patients were included and divided into difficult LC (DLC, n = 61) and nondifficult LC (non-DLC, n = 266). Multivariate logistic analysis revealed that symptom duration ≥72 h was the only independent risk factor for DLC. Comparison of late LC (beyond 72 h, LLC) and early LC (within 72 h, ELC) showed a lower rate of creation of the critical view of safety and a longer hospital stay, as well as a longer operative time, a larger amount of bleeding, and a higher open conversion rate in LLC. However, the postoperative complication rates were equivalent.

LC for AC with symptom duration ≥72 h tends to be technically difficult. However, it is acceptable regarding operative outcomes.
