Comparison of Early Results and Complications between Multi-and Single-Port Sleeve Gastrectomy: A Randomized Clinical Study

BACKGROUND In recent years, laparoscopic sleeve gastrectomy (LSG) has become more acceptable for obese patients. Single-port sleeve gastrectomy (SPSG) is more popular since each abdominal incision carries the risk of bleeding, hernia, and internal organ injury as well as exponentially affecting cosmesis. This cross-sectional study aimed at comparing multi-port sleeve gastrectomy (MPSG) and SPSG in terms of their early results and complications. METHODS Out of129 obese patients candidated for LSG, 102 patients were assigned to 2 groups of SPSG and MPSG. Complications and demographic data such as body mass index (BMI), age, gender, operation time, and hospital stay were measured. All surgeries were carried out between2013 and 2015 in Shiraz, Iran. Data analysis was performed using SPSS, version 16 for Windows (SPSS Inc., Chicago, IL). The continuous and categorical variables were compared using the Student t-test and the Chi-square test or the Fisher exact test, respectively. RESULTS The patients' data from both groups were similar in terms of age, intraoperative and postoperative bleeding volume, and length of hospital stay. Mean BMI was 42.8±0.7 in the SPSG group and 45.3±1.2 in the MPSG group. Duration of surgery was significantly lower in the SPSG group (P<0.001). Only 1 patient from the SPSG group and 5 patients from the MPSG group had bleeding as an early complication. CONCLUSION The differences in each complication between the groups were not statistically significant. SPSG seems to be safe and is the same as MPSG in terms of major postoperative complications.
