Long or Very Long-Limb Gastric Bypass in Superobese

2014-08-26 22:23:24 | BioPortfolio


The goal of this study is to compare the clinical efficacy (weight loss and metabolic changes) of long (150 cm) versus very long (250cm) Roux alimentary limb gastric bypass in superobese (BMI>50) patients.


The study is a multicentre trial in which superobese (BMI>50) patients will be randomly assigned (in a 1:1 ratio) for laparoscopic gastric Roux-en-Y gastric bypass with: a) long (150 cm) or b) very long (250cm) alimentary Roux limb. Patients will be included from three hospitals: Kaunas University of Medicine Hospital (Lithuania), Klaipeda District Hospital (Lithuania), Vaasa Central Hospital (Finland) ) where preoperative investigation, the same technique surgical procedures and follow up will be performed acording approved protocol.

Approximate duration of subject participation

Subjects in the study will participate for approximately 5 years:

- Preoperative investigation and surgery 3- 5 days in the hospital;

- First follow up visit: 6 months after surgery;

- Next follow up visits: 12, 24, 36, 48 months after surgery;

- Last follow up visit: 5 years after surgery.

- The interim results after 12, 24 and 36 months will be calculated and presented before end of the study.

Medical and Biotech [MESH] Definitions

Abnormal distention of the STOMACH due to accumulation of gastric contents that may reach 10 to 15 liters. Gastric dilatation may be the result of GASTRIC OUTLET OBSTRUCTION; ILEUS; GASTROPARESIS; or denervation.

Vagal denervation of that part of the STOMACH lined with acid-secreting mucosa (GASTRIC MUCOSA) containing the GASTRIC PARIETAL CELLS. Since the procedure leaves the vagal branches to the antrum and PYLORUS intact, it circumvents gastric drainage required with truncal vagotomy techniques.

Rounded or pyramidal cells of the GASTRIC GLANDS. They secrete HYDROCHLORIC ACID and produce gastric intrinsic factor, a glycoprotein that binds VITAMIN B12.

A synthetic methylprostaglandin E1 analog that reduces gastric acid secretion and enhances the gastric mucus-bicarbonate barrier. It is effective in the therapy of gastric ulcers and gives significant protection against NSAID-induced gastric mucosal damage. The drug also prevents cyclosporin A-induced damage to endocrine and exocrine pancreatic secretions. It shows a low order of acute toxicity and there is no evidence of embryotoxicity, fetotoxicity, teratogenicity, or mutagenicity in animal studies.

A subtype of cholecystokinin receptor found primarily in the CENTRAL NERVOUS SYSTEM and the GASTRIC MUCOSA. It may play a role as a neuromodulator of dopaminergic neurotransmission the regulation of GASTRIC ACID secretion from GASTRIC PARIETAL CELLS.
