Robotic sleeve gastrectomy (RSG) and laparoscopic sleeve gastrectomy (LSG) show comparable safety profiles. Standardized Clavien-Dindo classification (CDC) grading revealed no significant differences in complication rates between RSG and LSG after adjusting for patient factors.

Area of Science:

  • Bariatric Surgery
  • Surgical Outcomes
  • Medical Device Technology

Background:

  • Clavien-Dindo classification (CDC) application in MBSAQIP studies lacked standardization.
  • Previous comparative safety data for robotic (RSG) versus laparoscopic sleeve gastrectomy (LSG) were inconsistent.

Purpose of the Study:

  • To standardize Clavien-Dindo classification (CDC) grading for sleeve gastrectomy complications using treatment-level data.
  • To compare the 30-day safety outcomes between robotic sleeve gastrectomy (RSG) and laparoscopic sleeve gastrectomy (LSG).

Main Methods:

  • Retrospective cohort study using 2020-2023 MBSAQIP data.
  • Assignment of CDC grades based on treatment interventions (reoperation, reintervention, readmission, ICU care).
  • Comprehensive Complication Index (CCI) calculation and multivariable regression analysis.

Robotic Myotomy and Partial Fundoplication for Achalasia

Published on: August 11, 2023

Main Results:

  • Analysis of 480,280 sleeve gastrectomies (73% LSG, 27% RSG).
  • RSG cohort exhibited higher BMI, greater proportion of Black patients, and more comorbidities.
  • Adjusted analysis revealed no significant differences in CDC grades or high CCI between RSG and LSG.

Conclusions:

  • First study to assign MBSAQIP complications to CDC grades using treatment details.
  • Robotic sleeve gastrectomy (RSG) and laparoscopic sleeve gastrectomy (LSG) demonstrate comparable safety profiles.
  • Standardized CDC grading supports consistent evaluation of bariatric surgery complications.
