Introduction: Single-incision laparoscopic cholecystectomy (SILC) is widely used as a treatment option for gallbladder disease. However, obesity has been considered a relative contraindication to this approach due to more advanced technical difficulties. The aim of this report was to review our experience with SILC to evaluate the impact of body mass index (BMI) on the surgical outcome. Patients and Methods: Between May 2009 and February 2013, 237 patients underwent SILC at our institute. Pre- and post-operative data of the 17 obese patients (O-group) (BMI ≥30 kg/m2) and 220 non-obese patients (NO-group) (BMI <29.9 kg/m2) were compared retrospectively. SILC was performed under general anaesthesia, using glove technique. Indications for surgery included benign gallbladder disease, except for emergent surgeries. Results: Mean age of patients was significantly higher in the NO-group than O-group (58.9 ± 13.5 years vs. 50.8 ± 14.0 years, P = 0.025). SILC was successfully completed in 233 patients (98.3%). Four patients (1.7%) in the NO-group required an additional port, and one patient was converted to an open procedure. The median operative time was 70 ± 25 min in the NO-group and 75.2 ± 18.3 min in the O-group. All complications were minor, except for one case in the NO-group that suffered with leakage of the cystic duct stump, for which endoscopic nasobiliary drainage was need. Conclusion: Our findings show that obesity, intended as a BMI ≥30 kg/m2, does not have an adverse impact on the technical difficulty and post-operative outcomes of SILC. Obesity-related comorbidities did not increase the risks for SILC.
