“…Sleeve gastrectomy with transit bipartition (SG-TB) has been gaining attraction from many surgeons [ 1 – 5 ]. SG-TB is a relatively new surgical concept developed by Sergio Santoro and has been reported to have significant outcomes in terms of weight reduction, improvement of metabolic syndromes, and improvement of gastroesophageal reflux disease (GERD) [ 1 – 3 ]. The dual delivery system of the SG-TB carries a prospect of reducing nutritional complications and preserving overall clinical safety while maintaining excellent bariatric and metabolic outcome [ 1 – 3 ].…”

Background Sleeve gastrectomy with transit bipartition (SG-TB) procedure has been gaining traction recently. While being a relatively novel procedure, it shows potentials to improve the standalone SG outcomes, such as diabetes remission and reflux. This article aims to show insights on performing SG-TB in one anastomosis fashion (SG-OATB) and single-port approach. Methods Three patients who underwent laparoscopic single-port SG-OATB at our hospital were included. The parameters included in this study comprised of age, gender, height, weight, body mass index (BMI), type 2 diabetes mellitus (T2DM) assessment, gastroesophageal reflux disease (GERD) assessment, length of the small bowel, the duration of the procedure, and 30-day readmission rate. Results The mean preoperative assessments for the three patients were as follows: two females vs. one male; age 38.7 ± 5.5 years old; weight 105.7 ± 5.4 kg; height 1.64 ± 0.11 m; BMI 39.3 ± 4.7 kg/m2; fasting blood glucose 6.7 ± 1.2 mmol/L; glycosylated hemoglobin level 7.1 ± 1.3%; GERD-Questionnaire score 6.3 ± 1.5; two patients with esophagitis grade A and B following endoscopy. The total duration of the procedure was 170.0 ± 26.5 min; there was no need for conversion to multiple-port in all patients. The 30-day readmission rate for all patients was 0%. Conclusion In our small cases of patients, single-port SG-OATB is feasible and safe. We found the closure of the anastomosis defect to be most technically demanding. To understand better the outcome of single-port SG-OATB, studies with larger sample and longer follow-up will be needed in the future.

“…Ribeiro et al, in a retrospective study of 68 patients with 5 years of follow-up, with a similar technique as we presented, showed 5.9% hypoproteinemia and 14.7% low vitamin D and folate levels. Thus, the site of anastomosis has no significant impact on the passage of food or malnutrition rates [3].Preoperative workup with protein and vitamin levels, including serum albumin, iron, ferritin, vitamin B12, zinc, magnesium, vitamin D, and calcium, were measured and corrected for all patients before the index operation.The alarming outcomes in our series derived from the adverse effects of the Achilles heel of SASI and all emerging procedures that rely on malabsorption [4] and are unrelated to the size or site of the anastomosis.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.…”

We thank Abokhozima and Zidan for their comments on our study, and we are happy to address their questions.Single anastomosis sleeve ileal bypass (SASI) has a low perioperative complication rate, short-term significant weight loss, and resolution of obesity-related complications. However, this comes with a high expense of malnutrition, even in our short-term follow-up series with a 20% revision rate [1].The size of the gastro-ileal anastomosis in our series was 40 mm and not 60 mm. According to a systematic review and meta-analysis of 941 patients that underwent SASI, examining the effect of the size of the gastro-ileal anastomosis on % excess weight loss (EWL) and complications, comparing 4 to 3 cm anastomosis, revealed that a 4-cm anastomosis had better EWL at 12 months (94.3% vs 79.7%) and less complication rate (2.6% vs 14.4%) [2].The site of the gastro-ileal anastomosis in our series was at the greater curve of the antrum, as seen in the video. Ribeiro et al., in a retrospective study of 68 patients with 5 years of follow-up, with a similar technique as we presented, showed 5.9% hypoproteinemia and 14.7% low vitamin D and folate levels. Thus, the site of anastomosis has no significant impact on the passage of food or malnutrition rates [3].Preoperative workup with protein and vitamin levels, including serum albumin, iron, ferritin, vitamin B12, zinc, magnesium, vitamin D, and calcium, were measured and corrected for all patients before the index operation.The alarming outcomes in our series derived from the adverse effects of the Achilles heel of SASI and all emerging procedures that rely on malabsorption [4] and are unrelated to the size or site of the anastomosis.Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.
