Single-Site Robotic Cholecystectomy in a Broadly Inclusive Patient Population A Prospective Study

Objectives: To describe our initial experience with single-site robotic cholecystectomy (SSRC) and its applicability to a broad segment of patients. Background: At the initiation of our study, there were only 3 published reports on SSRC. These initial studies had limited inclusion criteria. We present our experience with the technical aspects and patient outcomes of SSRC in a broadly inclusive patient population. Methods: Prospective cohort study from January 2012 to January 2013, in which 95 patients underwent SSRC. Procedural times, postoperative complications, delayed hospital discharges, and re-admissions were evaluated. Results: Patients were predominantly female (71.6%) had mean age of 45.2 +/- 6.1 years and mean body mass index (BMI) of 30.1 +/- 7.1 kg/m(2). Overall, mean total operative time (TOT) for all patients (n = 95) was 88.63 +/- 32.0 (range: 49-220) minutes. SSRC was not completed in 8 (8.42%) patients: 6 conversions to laparoscopy, 1 conversion to open, and 1 aborted case. The group of patients who were able to complete SSRC (n = 87) had a mean TOT of 83.5 +/- 24.5 minutes and mean operative robotic time (RT) of 39.6 +/- 15.2 minutes. RT was longer in patients with intra-abdominal adhesions (P = 0.0139) and higher BMI (P = 0.03). A minority of patients required hospital admission (11.6%), readmission (6.3%), or reoperation (1.1%). No bile duct injury or death occurred. Conclusions: SSRC is safe and has a manageable learning curve. Patient factors, such as obesity, did not significantly affect conversion rates or TOTs. SSRC is a promising new technique, which can be offered to a wide array of patients.
