Background: Minimally invasive surgery seems particularly suited to adolescents in view of the cosmetic improvements it provides. This study reports on our first experience of single-incision laparoscopic surgery for adjustable gastric banding (SILS-AGB) using a single-trocar approach and evaluates its safety and efficacy as compared with conventional four-trocar laparoscopy.
Methods: The data of adolescent patients who underwent SILS-AGB or conventional laparoscopy for adjustable gastric banding (CL-AGB) between 2014 and 2019 in our center were reviewed. Pre- and postoperative data on weight- and obesity-associated comorbidities were used to assess the efficacy of the surgical intervention. Perioperative and postoperative data on the duration of surgery, use of analgesics, hospital stay, and complications were compared between the SILS and CL groups along with an assessment of scar quality.
Results: Overall, 12 patients, with a mean body mass index (BMI) of 43.3 kg/m² (37.0-55.5) at surgery were included in the SILS-AGB group and compared with 14 patients who underwent classic laparoscopy (CL-AGB group) and had an initial BMI of 39.5 kg/m² (32.0-49.8). Median surgery time was 82 min (55-140) in the CL-AGB group and 106 min (75-159) in the SILS-AGB group (p = 0.04). Postoperative recovery was better in the SILS-AGB group with a mean duration of level-3 intravenous analgesia of 1.8 ± 0.4 days (vs. 2.4 ± 0.6 days, p = 0.02) and a median duration of hospitalization of 2 days (2-3) versus 3 days (2-5) (p = 0.0005). Mid-term follow-up showed equivalent efficacy in terms of weight loss, with a mean BMI at 12 months of 38.5 ± 6.0 kg mkg m² in both groups, and resolution of hyperinsulinism (92.3 % before surgery vs. 48 % at 6 months).
Conclusion: SILS for AGB placement appears to be as safe and effective as CL despite a slightly longer operative time. SILS was associated with faster recovery and better cosmetic results with a single scar.

Background: Several retrospective studies suggest that adding a non-adjustable silicone ring to a Roux-en-Y gastric bypass (RYGB) results in more weight loss and prevents weight regain in the long term. The aim of this study was to evaluate the effect of a banded Roux-en-Y gastric bypass (B-RYGB) on weight loss outcomes in a randomized controlled trial (RCT).
Methods: In this single center RCT, 130 patients were divided into two groups: a standard Roux-en-Y gastric bypass (S-RYGB) or a B-RYGB using a Minimizer® ring.
Introduction: Adjustable intragastric balloon (aIGB), as known as a novel minimally invasive therapy for obesity, provide a sustained alternative for weight loss. Weight loss is achieved by implanting a balloon into the patient's stomach, with the volume of the balloon being adjustable through the injection or extraction of physiological saline. Its key distinction from other intragastric balloons lies in post-implantation volume control.

Background: Globally, many surgeons perform varying revisional procedures to convert either a primary sleeve gastrectomy (SG) or laparoscopic adjustable gastric band (LAGB) for the management of recurrent weight gain. There is no consensus on efficacious revision surgery in terms of long-term weight loss and comorbidity management. Nationally, the most common revision procedure is to a Roux-en-Y gastric bypass (RYGB).
