The effect of antral resection start point on post sleeve gastrectomy gastroesophageal reflux symptoms and weight loss outcomes.

PURPOSE: Sleeve gastrectomy (SG) has gained worldwide popularity by surgeons due to acceptable results in weight loss and obesity-associated medical problems. Distance from the pylorus during antral resection in SG may be effective in decreasing the occurrence of gastroesophageal reflux disease (GERD). The aim of this study was to evaluate GERD symptoms and weight loss outcomes in two groups of SG patients with different start points of antral resection. METHODS: This is a prospective cohort study on 220 patients who underwent SG between June 2019 and July 2021, aged 18 and above, BMI ≥ 40 kg/m2, or BMI > 35 kg/m2 with at least one obesity-associated medical problem. According to the start point of antral resection the patients were divided in two groups (group A: from 2 cm of pylorus and group B: from 4 cm of pylorus). Evaluation of GERD was performed using GerdQ questionnaire at 12-month follow up. RESULTS: Mean age and BMI of all patients were 37.6 ± 10 year and 44.8 ± 5.7 kg/m2 at the time of SG. Totally 153(69.5%) of the patients were female. De novo GERD after 12 months in the groups A and B was found in 18 (20%) and 19 (21%) patients. TWL% at 12-month follow ups, were 33.9% and 32.5% in group A and B, respectively. CONCLUSION: Antral resection's start point has no statistically significant effect on the excess and total weight loss indices, resolution of the obesity-related medical problems and De novo GERD between 2 and 4 cm start point for antral resection during SG.

Post-Bariatric Splenic Complications; Diagnosis and Treatment. A Systematic Review.

This systematic review intends to evaluate incidence and symptoms of post-bariatric splenic complications as well as best available modalities establishing the diagnosis and management protocols. A systematic literature search was performed in electronic database until March 2022. A total of 41 articles were included on the subject of splenic complications following bariatric/metabolic surgery (BMS). Splenic abscess was the most common splenic complications (44.2%) after BMS and leak was the most common reported etiology of the splenic abscess. Fever and abdominal pain were the most common presenting symptom in all splenic complications and CT scan was the most common diagnostic modality. Splenic complications after BMS are relatively rare but may lead to dangerous consequences. Prompt diagnosis and treatment can prevent potentially life-threatening outcomes.

One anastomosis gastric bypass as a one-stage bariatric surgical procedure in patients with BMI ≥ 50 kg/m2.

In patients with BMI ≥ 50 kg/m2, it is difficult to select an appropriate procedure that can lead to optimum results. This study aims to evaluate mid-term weight loss outcomes in patients with BMI ≥ 50 kg/m2 following one anastomosis gastric bypass (OAGB) as a one-stage procedure. A prospective study was conducted on patients with BMI ≥ 50 kg/m2, aged 18 years and above who had undergone primary OAGB from January 2016 to February 2019 with at least two years follow-ups. A total of 197 patients with BMI ≥ 50 kg/m2 had underwent OAGB. The mean age was 38 years and the mean pre-operative BMI was 53.7 kg/m2. Mean EWL% were 63.7%, 67.8% and 66.2% at one, two and five years after OAGB respectively. The highest level of EWL% was 68.4%, which was achieved in the 18th month following OAGB. OAGB can be performed safely in patients with BMI ≥ 50 kg/m2 as a one-stage procedure with acceptable weight loss outcomes and remission of obesity associated medical problems.
