Gastric Bypass with and Without Gastric Ring for the Treatment of Morbid Obesity: Results from Retrospective Analysis of a Prospective Database.

To assess the medium-term weight loss and maintenance of lean body mass (ideal weight/weight loss maintenance) following the Roux-en-Y gastric bypass (RYGB) surgical procedure with or without the use of a rigid gastric ring. An observational cohort study with a retrospective approach was conducted to evaluate the effectiveness of RYGB with and without a band in patients with morbid obesity. The outcomes were assessed by analyzing data obtained from medical records, including pre- and postoperative data.

QUALITY OF LIFE USING EURAHS-QoL SCORES AFTER SURGICAL TREATMENT OF INGUINAL HERNIA: LAPAROSCOPIC TRANSABDOMINAL PREPERITONEAL (TAPP) AND LICHTENSTEIN TECHNIQUES.

Background: Results on quality of life after inguinal hernia surgery, such as esthetics, postoperative pain, period of absence from activities, and recurrence are a relevant topic since inguinal hernia affects 27% of men and 3% of women at some point in their lives, and should guide health policies to allocate resources more efficiently.

Aims: To evaluate the quality of life in the late postoperative period of inguinal herniorrhaphy regarding recurrence, pain, esthetics, and restriction in activities, comparing the minimally invasive techniques - the transabdominal preperitoneal (TAPP) and the conventional Lichtenstein.

Methods: A cross-sectional observational clinical study was conducted with the EuraHS-QoL questionnaire validated and translated into Portuguese, applied to patients after an average of 65 months postoperatively.

Weight and Glucose Control in Rats Submitted to Sleeve Gastrectomy with Cafeteria Diet-Induced Obesity.

Sleeve gastrectomy (SG) has been widely disseminated as a surgical treatment for obesity and associated comorbidities, and currently it is one of the most performed surgeries in the world. Experimental research is becoming increasingly relevant to characterize the pathophysiological mechanisms induced by it. The aim of this study was to standardize an experimental model of SG in rats with obesity induced using a cafeteria diet (CAF) and evaluate variations in weight and glycemic control after vertical SG, maintaining the CAF.

Efficacy and Safety of Sleeve Gastrectomy with Jejunoileal Bypass Compared with Roux-en-Y Gastric Bypass: Results from a Cohort Study.

We previously described sleeve gastrectomy with jejunoileal bypass (SGJIB) as promising novel technique for the surgical treatment of obesity A retrospective analysis of a prospective database in a Private Practice of Alimentary Tract Surgery in São Paulo, Brazil. We analyzed 176 patients with 60 months of follow-up, 74 of whom underwent Vertical Sleeve Gastrectomy with Jejunoileal Bypass (VSG-JIB) (50 women and 24 men) with a mean age of 38 years and a mean body mass index (BMI) of 40 kg/m, and 102 patients underwent Roux-en-Y gastric bypass (RYGB) (90 women and 12 men) with a mean age of 36.5 years and a mean BMI of 39.

Thawed Porcine Model for Surgical Training: A Novel Conservative Procedure.

General Surgery course is a mandatory in medical schools and continuing surgery training is important even to experienced surgeons which they need to maintain and/or improve their surgical skills. Additionally, the models used for that practice are human cadavers, anesthetized porcine, or simulators and are not accessible for medicine schools or physicians in many countries. Therefore, we present a new technical procedure for preparation of frozen experimental animal's cadavers for medical surgical training.

30-Day Morbidity and Mortality of Bariatric Surgery During the COVID-19 Pandemic: a Multinational Cohort Study of 7704 Patients from 42 Countries.

Background: There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates.
