Comparison of sleeve volume between banded and non-banded sleeve gastrectomy: midterm effect on weight and food tolerance-a retrospective study

Article / Letter to editor
Background Sleeve dilatation after laparoscopic sleeve gastrectomy (LSG) causes weight regain (WR). Banded sleeve gastrectomy (BSG) was proposed to prevent dilatation and reduce WR. Methods A retrospective cohort study on patients who underwent BSG and LSG and completed 4 years of follow-up from 2016 to 2021 was included. Body mass index (BMI), percentage of excess weight loss (%EWL), percentage of total weight loss (%TWL), and FT scores were calculated at 1, 2, 3, and 4 years. The sleeve volume was estimated at 6 months, 1 year, and 4 years. Multi-variate analysis was conducted to assess correlations between covariates. WR was calculated as weight gain > 10%, > 10 kg above the nadir, or BMI increase of >= 5 kg/m(2) above the nadir. Results This study included LSG 1279 patients and BSG 132 patients. Mean %EWL at 1 year was 83.87 +/- 17.25% in LSG vs. 85.71 +/- 7.92% in BSG and was 83.47 +/- 18.87% in LSG and 85.54 +/- 7.48% in BSG at 4 years.

Mean %EWL at 1 year was 83.87 +/- 17.25% in LSG vs. 85.71 +/- 7.92% in BSG and was 83.47 +/- 18.87% in LSG and 85.54 +/- 7.48% in BSG at 4 years. Both had significant weight loss over time (p. < 0.001) with no significant main effect of surgery (p.0.438). Mean sleeve volume at 6 months was 102.32 +/- 9.88 +/- 10.28 ml in LSG vs. 101.89 +/- 10.019 ml in BSG and at 4 years was 580.25 +/- 112.25 ml in LSG vs. 157.94 +/- 12.54 ml in BSG (p. < 0.001). WR occurred in 136 (10.6%) and 4 (3.1%) (p.0.002) in LSG and BSG patients, 90 (7%) vs. zero (0%) (p.0.002) and 31 (2.4%) vs. zero (0%) (p.0.07) using the > 10%, > 10 kg increase above the nadir and the >= 5 kg/m(2) BMI increases above the nadir formulas, respectively. Conclusion BSG had significantly lower sleeve volume, significantly lower WR, and significantly lower FT scores than LSG after 4 years from surgery; however, volume changes were not correlated with weight loss.Show less
