“…However, the multivariate analysis revealed that the changes in the sleeve pouch volume did not correlate to the %EWL after 4 years of follow-up, while having a BMI ≥ 40 was the only predictive factor to have a higher average %EWL. Other studies reported similar results with no correlation between the sleeve pouch volume and weight loss [14,26,27]. Nevertheless, the BSG can add value in maintaining stomach volume and preventing WR in the longer follow-up phase since there was significantly more patient in the LSG with increased stomach volume and significantly lower incidence of WR.…”

“…Patients were instructed to fast for at least 4 h before examination and given an intravenous injection of 40 mg butyl-scopolamine and then asked to swallow 2 to 4 packs of effervescent granules (sodium bicarbonate) as tolerated on the table with no water. Performing the MSCT was funded by the university hospital for all the patients (A full description of the technique is in the Appendix) [ 14 ].…”

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. 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.

“…Sleeve volume by radiological assessment is a useful tool to report sleeve dilatation. This volumetric assessment can correlate dilatation and weight loss after LSG and BLSG [ 19 ]. Our clinic has experienced a rise in demand from patients with weight regain or insufficient weight loss who are hesitant to undergo revisional surgery other than LSG after comprehensive explanations of various BMS to all patients.…”

Two-Year Results of the Banded Versus Non-banded Re-sleeve Gastrectomy as a Secondary Weight Loss Procedure After the Failure of Primary Sleeve Gastrectomy: a Randomized Controlled Trial

et al. 2023

Background Insufficient weight loss or weight regain has been reported in up to 30% of patients after laparoscopic sleeve gastrectomy (LSG). Approximately 4.5% of patients who undergo LSG need revisional surgery for a dilated sleeve. Methods This randomized controlled trial compared the outcomes between banded (BLSG) and non-banded re-LSG (NBLSG) after weight regain. Percentage excess body weight loss (%EWL), percentage total weight loss (%TWL), associated medical problems, gastric volume measurement, and endoscopy were measured preoperatively and 1 and 2 years postoperatively. Results Both groups (25 patients each) achieved similar % EWL and %TWL at six months, one year, and two years postoperatively (%EWL 46.9 vs. 43.6, 83.7 vs. 86.3, and 85.7 vs. 83.9) (p= > 0.151) (%TWL 23.9 vs. 21.8, 43.1 vs .43.3, 44.2 vs. 42.2) (p=>0.342), respectively. However, the body mass index was significantly lower with BLSG (24.9 vs. NBLSG, 26.9). Both groups showed a significant reduction in stomach volume after two years (BLSG -248.4 mL vs. NBLSG -215.8 mL). Food tolerance (FT) scores were significantly reduced in both groups, whereby BSLG had significantly lower FT with an average of -1.1 point. No significant differences were observed regarding improvement of the associated medical problems after the first and two years after revisional LSG or the postoperative complications between both groups. Conclusion Laparoscopic re-LSG is feasible and safe with satisfactory outcomes in patients with weight regain after LSG who have gastric dilatation without reflux esophagitis. Both groups had comparable significant weight loss effects and improvement of associated medical problems. The BLSG tends to have a more stable weight loss after two years with a significantly lower BMI, lower stomach volume, and less weight regain. Food tolerance decreased in both groups but reduced more in the BLSG group. After a 2-year follow-up, we may regard both procedures are safe, with no significant differences in the occurrence of complications and nutritional deficits. Graphical Abstract
