Abstract

Background: Transcylindrical cholecystectomy (TC) can be performed under local anaesthesia and sedation (LAS) in ambulatory surgery (AS). The aim of this study was to assess the feasibility and results of TC under LAS.

Methods: TC under LAS was proposed to 583 consecutive patients with cholelithiasis in an AS unit. For the TC procedure, a cylindrical retractor with a transparent plunger was inserted into the hepatocystic triangle, and cholecystectomy was performed through the retractor with reusable open instruments. Pre-, intra-, and post-operative variables were prospectively registered, including complications, reasons for conversion to general anaesthesia (GA), non-programmed admissions, readmissions, pain assessments, and satisfaction with the procedure.

Results: Five hundred patients were eligible for LAS, with GA being required in 128 (25.6%) of them. AS was programmed for 447 patients. The rates of non-programmed admissions, readmissions, and conversion to laparotomy were 8.7% (39), 0.8% (4), and 2.6% (13), respectively. There was no main bile duct injury. At 24 h, physical status was good or excellent in 80.4% of the patients. A history of acute cholecystitis, male sex, a body mass index (BMI) ≥ 39.5 kg/m2, and non-suspected acute cholecystitis were found to be independent variables associated with conversion to GA.

Conclusions: TC under LAS is a safe procedure in AS and is feasible in 74% of cholelithiasis patients. Male sex, BMI, gallbladder wall thickness, and a history of acute cholecystitis are factors that increase the probability of conversion to GA. This prospective study was approved by the ethics committee of Badajoz for patient protection for biomedical research and has been retrospectively registered under the research registry UIN: researchregistry3979.
