Watch this detailed video demonstrating the step-by-step conversion from sleeve gastrectomy to Roux-en-Y gastric bypass performed at World Laparoscopy Hospital. This surgical video highlights advanced laparoscopic techniques, patient safety, and post-operative care, making it an essential learning resource for surgeons and medical professionals.

Gastric sleeve gastrectomy has become a frequent bariatric procedure. Its apparent simplicity hides a number of serious, sometimes fatal, complications. This is more important in the absence of an internationally adopted algorithm for the management of the leaks complicating this operation. The debates exist even regarding the definition of a leak, with several classification systems that can be used to predict the cause of the leak, and also to determine the treatment plan. Causes of leak are classified as mechanical, technical and ischemic causes. The management of leak post sleeve gastrectomy imposes a lot of controversies and difficulties in the adoption of a standard algorithm, Patients who fail initial conservative treatment, need a definitive surgical intervention with more aggressive and radical treatment, including either conversion to gastric bypass, or a Roux-En-Y with a jejunal limb oversewn over the fistula.

Conversion from Sleeve Gastrectomy to Roux-en-Y Gastric Bypass at World Laparoscopy Hospital

Bariatric surgery has revolutionized the management of obesity and associated metabolic disorders. Among the most commonly performed procedures, sleeve gastrectomy (SG) has gained immense popularity due to its simplicity and effectiveness. However, despite its initial success, some patients may experience complications or inadequate weight loss, necessitating a conversion to Roux-en-Y gastric bypass (RYGB).

At World Laparoscopy Hospital (WLH), Gurugram, India, such complex revisional procedures are performed with precision by a team of expert bariatric and laparoscopic surgeons. Conversion from SG to RYGB requires meticulous planning, advanced surgical skill, and a patient-centric approach to ensure optimal outcomes.

Indications for Conversion

Patients may require conversion from SG to RYGB for several reasons:

1. Inadequate weight loss or weight regain – When patients fail to achieve or maintain their target weight after SG.

2. Gastroesophageal reflux disease (GERD) – Severe reflux post-SG that is unresponsive to medical management.

3. Structural complications – Such as sleeve stenosis, strictures, or significant dilation of the gastric sleeve.

4. Metabolic issues – Persistent diabetes or other comorbidities not improving sufficiently after SG.

Preoperative Evaluation

At WLH, every patient undergoes a comprehensive assessment before revision surgery:

• Detailed medical and surgical history review.

• Laboratory and nutritional evaluation.

• Endoscopic and radiological assessment of the stomach anatomy.

• Individualized risk assessment and optimization for safe anesthesia.

Surgical Technique

The conversion procedure is technically demanding but highly effective when performed by experienced surgeons. Key steps include:

1. Adhesiolysis – Careful dissection to free adhesions from the previous SG.

2. Sleeve assessment – Evaluating sleeve size, shape, and any complications.

3. Creation of gastric pouch – Forming a small gastric pouch to limit food intake.

4. Roux limb construction – Bypassing a portion of the small intestine to induce malabsorption and hormonal benefits.

5. Gastrojejunostomy and jejunojejunostomy – Re-establishing intestinal continuity for effective digestion.

6. Leak test and closure – Ensuring no leaks or complications before completing the procedure.

WLH emphasizes minimally invasive laparoscopic techniques for these conversions, which significantly reduce postoperative pain, hospital stay, and recovery time while enhancing patient safety.

Postoperative Care and Follow-Up

Post-surgery, patients receive individualized nutritional counseling, vitamin and mineral supplementation, and structured follow-up to monitor weight loss, metabolic improvement, and overall health. Regular follow-ups help identify and manage any complications early.

Outcomes and Benefits

Conversion from SG to RYGB at WLH has shown excellent outcomes:

• Effective long-term weight loss.

• Significant improvement or resolution of GERD and metabolic disorders.

• Minimal complications when performed laparoscopically by skilled surgeons.

Conclusion

Revisional bariatric surgery, particularly conversion from sleeve gastrectomy to Roux-en-Y gastric bypass, represents a challenging but highly rewarding procedure. At World Laparoscopy Hospital, the combination of expert surgical skill, advanced laparoscopic technology, and comprehensive patient care ensures that patients achieve the best possible outcomes in terms of weight loss, metabolic health, and quality of life.

Patients considering revisional surgery are encouraged to consult with WLH’s bariatric team to evaluate suitability, understand the procedure, and receive personalized guidance for safe and effective results.
