Routine gastric suspension technique in single-port sleeve gastrectomy procedure

Due to limited technical demand, single-port sleeve gastrectomy (SPSG) is a feasible laparoscopic technique for sleeve gastrectomy (SG). Nonetheless, difficulties exist when performing the single-port technique, and in this study, we aim to describe a slight maneuver that can improve the SPSG procedure.

Patients who underwent laparoscopic SG between January 2022 and May 2023 at our hospital were included. The patients were classified into two groups: (1) SPSG and (2) multiple-port SG (MPSG). The parameters for this analysis were the patients' age, gender, weight, body mass index (BMI), conversion rate, drainage placement, 30-day readmission rate, and postoperative complications. Postoperative one-month and three-month percentages of total weight loss (%TWL) were calculated and compared.

171 patients were included in this study: (1) the SPSG group (n = 96) and (2) the MPSG group (n = 75). No statistically significant difference was observed within the preoperative (age, gender, height, weight, and BMI) and the perioperative parameters between SPSG and MPSG (operation time, drainage placement, 30-day readmission) (p > 0.05). Per Clavien-Dindo's grading, two patients in the SPSG group suffered grade 1 complications; for the MPSG group, one patient sustained grade 2 and another suffered grade 3b complication. No statistical significance was observed on the %TWL between the two groups (p > 0.05).

Our study found that performing SPSG in specific patient is feasible and non-inferior when compared to the MPSG. Further studies will be needed to elucidate better the efficacy and safety of performing SPSG.
