Primary silicone-banded laparoscopic sleeve gastrectomy: a pilot study

Area of Science:

• Bariatric Surgery
• Minimally Invasive Surgery
• Gastroenterology

Background:

• Inadequate weight loss and weight regain are common challenges with existing bariatric surgical procedures.
• Reinforcing rings have been proposed for gastric bypass and sleeve gastrectomy to improve outcomes.
• This study evaluates the initial feasibility and efficacy of silicone-banded laparoscopic sleeve gastrectomy (LSG).

Purpose of the Study:

• To assess the initial feasibility of silicone-banded LSG.
• To evaluate the short-term efficacy of silicone-banded LSG in terms of weight loss.
• To determine the perioperative and postoperative complication rates associated with silicone-banded LSG.

Main Methods:

• Retrospective analysis of all silicone-banded LSG cases performed at a single center.
• Extraction and analysis of patient demographics, operative parameters, and postoperative outcomes.
• Evaluation of complications, operative time, blood loss, and excess weight loss (EWL).

Main Results:

• Thirteen patients (mean BMI 53.7 kg/m²) underwent the procedure.
• Mean operative time was 140.7 minutes with minimal blood loss; no mortalities occurred.
• At 16 months median follow-up, mean BMI decreased to 38.7 kg/m², with 54.8% excess weight loss (EWL).

Conclusions:

• Silicone-banded LSG is a feasible bariatric surgical option.
• The procedure demonstrates minimal short-term morbidity.
• Significant excess weight loss (EWL) was observed in the short term.
