Revision/Conversion Surgeries After One Anastomosis Gastric Bypass-An Experts' Modified Delphi Consensus.

Purpose: There is a lack of evidence for treatment of some conditions including complication management, suboptimal initial weight loss, recurrent weight gain, or worsening of a significant obesity complication after one anastomosis gastric bypass (OAGB). This study was designed to respond to the existing lack of agreement and to provide a valuable resource for clinicians by employing an expert-modified Delphi consensus method.

Methods: Forty-eight recognized bariatric surgeons from 28 countries participated in the modified Delphi consensus to vote on 64 statements in two rounds.

Patient Selection in One Anastomosis/Mini Gastric Bypass-an Expert Modified Delphi Consensus.

Purpose: One anastomosis/mini gastric bypass (OAGB/MGB) is up to date the third most performed obesity and metabolic procedure worldwide, which recently has been endorsed by ASMBS. The main criticisms are the risk of bile reflux, esophageal cancer, and malnutrition. Although IFSO has recognized this procedure, guidance is needed regarding selection criteria.

Roux-en-Y to One Anastomosis Gastric Bypass Conversion: Description of a Novel Technique.

Roux-en-Y gastric bypass (RYGB) remains among the most widely performed bariatric procedures. A significant decline in its indication has been observed due to weight regain and reappearance of comorbidities. Moreover, the lack of effective therapeutic alternatives after failure justifies why other techniques are more frequently chosen.

Laparoscopic resection of gastric schwannoma: A case report.

Introduction: Gastric schwannomas are an extremely rare presentation of mesenchymal tumors originating from Schwann cells, accounting for 0.2% of all gastric tumors. Patients are usually asymptomatic, so these tumors are frequently detected incidentally.

Are There Ideal Small Bowel Limb Lengths for One-Anastomosis Gastric Bypass (OAGB) to Obtain Optimal Weight Loss and Remission of Comorbidities with Minimal Nutritional Deficiencies?

Background: Ideal jejunal and ileal lengths in bariatric/metabolic procedures to be left in alimentary continuity still remain unclear. We aimed to evaluate different lengths of biliopancreatic limb (BPL) and common limb (CL) performed in a series of patients submitted to OAGB, and correlate them with weight loss and nutritional deficits.

Patients And Methods: A prospective observational study of 350 consecutive morbidly obese patients undergoing OAGB was performed.

One Anastomosis Gastric Bypass in Morbidly Obese Patients with BMI ≥ 50 kg/m: a Systematic Review Comparing It with Roux-En-Y Gastric Bypass and Sleeve Gastrectomy.

Background: To explore the role of one anastomosis (Mini) gastric bypass (OAGB) for the super-obese patients.

Method: Literature review was performed in March 2019 as per PRISMA guidelines.

Results: A total of 318 patients were identified.

A 5-Year Follow-up in Children and Adolescents Undergoing One-Anastomosis Gastric Bypass (OAGB) at a European IFSO Excellence Center (EAC-BS).

Background: The children and adolescent population with obesity has increased worldwide, both in developing areas and in developed countries. Consequently, the prevalence of morbid obesity among this population has also increased, leading to an exponential growth of bariatric approaches in this population. Many surgeons fear eventual nutritional sequelae after malabsorptive approaches and prefer restrictive or mixed procedures.

Whipple disease after bariatric surgery: from malabsorption to malnutrition status.

Malabsorptive bariatric techniques are associated with nutritional deficiencies. However, when patients do not respond to supplemental intensive treatments they should be closely followed because they can hide other pathological conditions. We present the case of a 47-year-old man with morbid obesity (body mass index [BMI]: 48 kg/m2) who underwent bariatric surgery.

Results after Definitive Surgical Treatment in Patients with Enteroatmospheric Fistula.

As enteroatmospheric fistulas (EAF) lack healthy overlying tissue, spontaneous healing is very unlikely. Our aim was to identify risk factors for recurrence and mortality after definitive surgical treatment for EAF. Sixty-two consecutive patients with a diagnosis of EAF were submitted to definitive surgical repair (fistula resection and primary anastomosis) during a 6-year period.

Evaluation of Weight Loss Indicators and Laparoscopic One-Anastomosis Gastric Bypass Outcomes.

Mini-gastric bypass/One-anastomosis gastric bypass (MGB-OAGB) is an effective bariatric technique for treating overweight and obesity, controlling and improving excess-weight-related comorbidities. Our study evaluated OAGB characteristics and resulting weight evolution, plus surgical success criteria based on various excess weight loss indicators. A prospective observational study of 100 patients undergoing OAGB performed by the same surgical team (two-year follow-up).

Laparoscopic One-Anastomosis Gastric Bypass: Technique, Results, and Long-Term Follow-Up in 1200 Patients.

Background: Excellent results have been reported with mini-gastric bypass. We adopted and modified the one-anastomosis gastric bypass (OAGB) concept. Herein is our approach, results, and long-term follow-up (FU).

Pulmonary extraskeletal myxoid chondrosarcoma: A case report and literature review.

Background: Extraskeletal myxoid chondrosarcoma (EMC) accounts for the 3% of all soft tissue sarcomas and it's categorized as a tumour of uncertain differentiation. This entity has shown to have the recurrent balanced chromosomal translocation t(9;22) (q22;q12.2), which leads to the oncogenic fusion gene EWSR1-NR4A3.

[Clinical and biochemical characteristics of patients with morbid obesity at the time of hospital admission and one year after undergoing bariatric surgery].

Background: Three percent of Mexicans suffer from morbid obesity. Comorbidities associated to this condition diminish quality of life, increase mortality and health care costs. Despite bariatric surgery has specific indications and risks, it is the only treatment with effective long-term results.

Predictive value of preoperative serum C-reactive protein for recurrence after definitive surgical repair of enterocutaneous fistula.

Background: Recurrence rates after surgical repair of enterocutaneous fistula (ECF) have not changed substantially. Serum C-reactive protein (s-CRP) has been used as an indicator of postoperative complications in abdominal surgery. ​ The aim of this study was to determine the predictive value of preoperative s-CRP for recurrence after definitive surgical repair of ECF.

Weight loss and improvement of lipid profiles in morbidly obese patients after laparoscopic one-anastomosis gastric bypass: 2-year follow-up.

Background: Obesity is the most frequent chronic metabolic disease globally. There is a direct correlation between increasing body mass index (BMI) and elevated total cholesterol (TC), low-density lipoprotein cholesterol (LDL), and triglycerides (Tg), and an inverse correlation with high-density lipoprotein cholesterol (HDL); all these lipid derangements are associated with an increased risk of cardiovascular disease. Our aim was to evaluate lipid profiles in morbidly obese patients before and after one-anastomosis gastric bypass (OAGB) performed at a single-center during a 2-year follow-up.

Mammary analog secretory carcinoma of the parotid gland: A case report and literature review.

Background: Mammary analog secretory carcinoma (MASC) was first described in 2010 by Skálová et al. This entity shares morphologic and immunohistochemical features with the secretory carcinoma (SC) of the breast. MASC usually presents as an asymptomatic mass in the parotid gland and predominantly affects men.
