Routine gastric suspension technique in single-port sleeve gastrectomy procedure

Abstract

Background: 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.

Methods: 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.

Results: 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).

Conclusion: 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.
