Analysis of post-operative complication in single-port laparoscopic cholecystectomy: A retrospective analysis in 817 cases from a surgeon

Background: Single-port laparoscopic cholecystectomy (SPLC) is a new advanced technique in laparoscopic surgery which has many benefits according to previous reports. The purpose of this study was to present personal experiences with SPLC in >800 cases performed by a surgeon to evaluate the safety and feasibility of this procedure. Materials and Methods: A retrospective review of 817 cases of SPLC was conducted. All patients had received elective SPLC by a surgeon in our centre during March 2009–August 2015. Our review suggests patients’ character, peri-operative data and post-operative outcome. Results: Three hundred and ninety-eight men (48.7%) and 419 women (51.3%) with an average age of 48.3 years had received SPLC. Their mean body mass index (BMI) was 23.75 kg/m 2 . The mean operating time took 46.9 min (19–130). Seventy-nine cases (9.7%) needed additional port during operation. BMI, age and previous abdominal surgical history did not affect conversion to multiport surgery. Bile spillage during operation occurred in 73 cases (8.9%). There were 4 cases of open conversion because of bleeding (2 cases, 0.2%) and common bile duct (CBD) injury (2 cases, 0.2%). Mean duration of hospital stay was 2.36 days. We have experienced 38 cases (4.7%) of post-operative complication: 8 cases (1.0%) of major one and 30 cases (3.7%) of minor one. Major complication occurred in 3 cases (0.4%) of retained CBD stone, 3 cases (0.4%) of cystic duct leakage needed endoscopic retrograde cholangiopancreatography and 2 cases (0.2%) of CBD injury needed reoperation. Most minor complications were wound infections that have healed after conservative treatment. There were no post-operative mortalities. Conclusion: SPLC is a safe and practicable technique. With surgical experience, criteria and area of SPLC can be broadened. SPLC is occupying a greater domain of a laparoscopic cholecystectomy.
