What this trial studies

This study investigates the effects of tailoring limb lengths based on the 1/3rd and 2/3rd concept in Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) surgery. Participants are divided into two groups: one receiving conventional limb lengths of 75cm and 125cm, and the other receiving tailored limb lengths according to their total small bowel length. The study aims to assess total percentage weight loss, improvement in BMI, and remission of obesity-related comorbidities during the follow-up period.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-65 with a BMI of 40 kg/m² or higher, or 35 kg/m² with obesity-related comorbidities.

Not a fit: Patients with previous bariatric surgery or severe cardiopulmonary conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved weight loss outcomes and better management of obesity-related health issues for patients.

How similar studies have performed: While the concept of tailored limb lengths is innovative, similar studies have not been widely reported, making this approach relatively novel.

Eligibility criteria

Inclusion Criteria:

1. Age: 18-65 years
2. Body Mass Index (BMI):

   BMI ≥ 40 kg/m² or BMI ≥ 35 kg/m² with at least one obesity-related comorbidity (e.g., type 2 diabetes, hypertension, obstructive sleep apnea).
3. ASA - less than or equal to 3
4. Informed Consent: Ability and willingness to provide written informed consent and comply with procedures.
5. Previous Weight Loss Attempts: Documentation of previous attempts at weight loss through diet, exercise, or medical management.

Exclusion Criteria:

1. Previous Bariatric Surgery: Prior bariatric or major gastrointestinal surgery that might affect the outcome of RYGB.
2. Severe Cardiopulmonary Conditions: Significant cardiac or pulmonary conditions that pose a high surgical risk (e.g., severe congestive heart failure, severe chronic obstructive pulmonary disease).
3. Uncontrolled Psychiatric Disorders: Severe psychiatric illness or substance abuse issues that are not well-controlled, including eating disorders.
4. Pregnancy: Current pregnancy or plans to become pregnant within 12 months post-surgery.

6. Severe Liver Disease: Cirrhosis or significant liver dysfunction (e.g., Child-Pugh B or C).
7. Inability to Comply: Patients who are unable or unwilling to comply with the postoperative follow-up schedule and dietary requirements.
8. Chronic Use of Medications: Chronic use of medications known to affect weight or metabolism significantly, such as corticosteroids or antipsychotics.
9. Other Medical Conditions: Any other medical condition or surgical finding that, in the opinion of the investigators, would make the patient unsuitable for the study.
