Sleeve Gastrectomy With Uncut Jejunal Bypass (SG-uncut JJB) Verus Sleeve Gastrectomy in Obese Patients

August 27, 2020 updated by: Zhen Jun Wang

Sleeve Gastrectomy With Uncut Jejunal Bypass (SG-uncut JJB) Verus Sleeve Gastrectomy in Obese Patients, a Prospective Randomized Controlled Study

Among various bariatric procedures, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most frequently performed procedures worldwide. Though SG provides similar weight loss effect to RYGB in short-term follow-up, its long-term and very long-term weight loss effect was reported to be inferior to RYGB. Weight regain after SG remains the major concern after 2-year follow-up due to gradual loss of appetite suppression and lack of malabsorption function. SG plus procedures have been developed to strengthen the effect of SG on diabetes control. It has been reported that SG plus jejunojejunal bypass (SG - JJB) offered better weight loss than SG and similar weight loss to RYGB. The present study aims to evaluate the efficacy and safety of sleeve gastrectomy plus uncut jejunojejunal bypass (SG - uncut JJB).

Among various bariatric procedures, sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most frequently performed procedures worldwide. Though SG provides similar weight loss effect to RYGB in short-term follow-up, its long-term and very long-term weight loss effect was reported to be inferior to RYGB. Weight regain after SG remains the major concern after 2-year follow-up due to gradual loss of appetite suppression and lack of malabsorption function.

The present study aims to evaluate the efficacy and safety of sleeve gastrectomy plus uncut jejunojejunal bypass (SG - uncut JJB).

For SG-JJB procedure, after SG was finished, the jejunum was transected 20-cm distal to Treiz ligament. After that, another 200-cm jejunum was measured and side-to-side jejunojejunal anastomosis was made. The anastomotic and mesenteric defects were closed by hand suture.

For SG-uncut JJB procedure, the jejunum was not transected, only 200-cm jejunum 20-cm distal to Treiz ligament was measured and side-to-side jejunojejunal anastomosis was made. And the jejunum 3-5cm distal to the anastomosis was ligated with 10# suture.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
excessive weight loss
Time Frame: 1 year postoperatively
Percentage of excess weight loss (EWL) at any time postoperative was calculated as the amount of weight loss divided by the amount of excess weight times 100%.
