Reusable laryngoscope blades, which are the most commonly used devices for airway management, have been reported to be frequently contaminated and a possible source of infection. Although disposable laryngoscope blades are recommended to reduce the risk of infection, there are studies suggesting increased failed intubation attempt rates. The major cause of anesthesia-related mortality and morbidity is the failure of airway management. The incidence of difficult airway is reported to be 1-4% in normal population while it ranges up to 12-20% in obese patients. Following the introduction of disposable blades and considering the increased rate of failed intubation in obese patients with these devices, the investigators aimed to make a comparison of successful intubation rates of plastic and metallic disposable blades in morbidly obese patients
From the beginning of March 2020, lockdown regimens prevented patients with obesity from receiving bariatric surgery. Surgical emergencies and oncological procedures were the only operations allowed in public hospitals. Consequently, patients with morbid obesity were put in a stand-by situation. With the aim at exploring physical and psychological conditions of the investigators future bariatric surgery patients, the investigators built a Questionnaire concerning obesity and COVID-19.
Bariatric surgery (BS) has a history of new procedures and techniques arising and then disappearing due to problems and complications. The present is no different with new and old procedures changing with the regularity of night following day. One of the important questions today in BS is the length and or need/value of the Biliopancreatic limb bypass (BPLL.) The Sleeve and the Band have "0" bypass, the RNY has a "short" bypass and the Biliopancreatic Diversion type procedures have a "long" (distal) bypass. The Mini-Gastric Bypass Original Technique (MGB-OT) version of the One Anastomosis Bypass (OAGB) includes a "medium" length of bypass, longer than the BPLL of the RNY and shorter than the the "Long" BPL of the BPD procedures. In addition, uniquely, the MGB-OT includes a "Tailored" BPLL. Not all OAGB surgeons use this approach and several have argued in favor of a "Fixed" BPLL of 150 cm. This paper is part of a series of studies of the "Tailored" BPLL specifically in MGB-OT patients. Notably it demonstrates in an online survey that patient reported weight loss and food choices change after MGB-OT and in addition the changes are related to the "Tailored" BPLL
Bariatric guidelines recommend preoperative weight loss of 5% to reduce the risk of surgical complications. However, results in the literature on the improvement of surgical procedure and outcomes are still conflicting. This study aims to evaluate the effect of preoperative weight loss by means of a 14-day low-calorie diet in bariatric patients on operative time, the ease of the Roux-en-Y gastric bypass (RYGB) procedure and long-term weight loss in a real-life experimental setting.
Background: Many of the beneficial metabolic effects of bariatric surgery have been attributed to altered peptide hormone profiles, especially involving pancreatic and gut peptides. Objectives: assess the effects of bariatric procedures (sleeve gastrectomy, minigastric bypass and sleeve gastrectomy with loop bipartition) on GIT hormones. Methods: Prospective randomized study which was carried out in the department of General Surgery, Minia University hospital during the period from February 2018 to February 2019. This study included 3 groups subjected to different operations; each group consisted of 50 patients.
Background: The investigators have found that obesity and insulin resistance result in significantly increased brain insulin-stimulated glucose uptake, whereas in every other tissue glucose uptake is lower in the obese compared to lean individuals. One possible explanation to this could be central inflammation and activation of brain glial cells, which has been shown to occur in animal models of obesity. Aims: The objective of this study is to investigate whether there is brain inflammation in human obesity, and whether weight loss following bariatric surgery decreases brain inflammation. Methods: A total of 60 morbidly obese subjects, assigned for Roux-en-Y gastric bypass or for sleeve gastrectomy according to routine treatment protocols will be recruited for this study. A control group of 30 healthy subjects will also be recruited. The following studies will be performed to patients and healthy subjects: 1) structural MRI and MRS, 2) functional MRI, 3) PET imaging of cerebral inflammation and astrocyte activation using [11C]-PK11195, 4) measurement of whole-body and tissue insulin sensitivity by combining hyperinsulinemic, euglycemic clamp with [18F]-FDG-PET, 5) neuropsychological testing. The study procedures will be repeated for the morbidly obese 6 months postoperatively.
Prospective randomized clinical trial aiming to compare a comprehensive, intensive behavioral lifestyle intervention and usual care during the preoperative preparation to bariatric surgery, with primary outcome on excess weight loss and secondary outcomes on patient's physical status, quality of life, comorbidity and technical difficulty of the surgery.
Investigators study the performance of both masks, Proseal Laryngeal Mask Airway (PLMA) and I-gel, as temporary ventilatory supraglottic airway devices (SGDs) before tracheal intubation in morbidly obese patients. Data are lacking in such population of patients
This study aims to determine the effect of two types of exercise training on body composition, cardiopulmonary function and quality of life in people after undergoing bariatric surgery.
