Long or Very Long-Limb Gastric Bypass in Superobese

Long or Very Long-Limb Gastric Bypass in Superobese

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.

Inclusion Criteria:

• Hospitalized male or female subjects 18-65 years of age.
• Obese subjects with body mass index (BMI= kg/m²)>50
• Patients without mental or nervous disorders interfering with adequate evaluation of one's health condition.
• Patients who read the informed consent form and gave a written consent to participate in the study.

Exclusion Criteria:
