It is considered when the patient has had multiple prior abdominal surgeries, has a very high BMI, or when laparoscopic conversion becomes necessary.

Open bariatric surgery involves making a large abdominal incision to directly access the stomach and surrounding organs. While laparoscopic techniques are preferred today, open surgery remains an important option for complex cases. The goal is to reduce the stomach size and alter the digestive pathway, resulting in reduced food intake, decreased calorie absorption, and significant long-term weight loss.

Conditions that may necessitate open bariatric surgery include:
Open bariatric procedures include open gastric bypass, open sleeve gastrectomy, open adjustable gastric banding, and open biliopancreatic diversion. Each procedure works differently but all aim to reduce stomach capacity and alter nutrient absorption. The choice of procedure is made based on the patient BMI, health status, and surgeon recommendation.
Open bariatric surgery is suited for patients with BMI above 40, or BMI above 35 with severe obesity-related health conditions. It is also recommended for patients who have extensive abdominal scar tissue, who have failed a prior laparoscopic bariatric procedure, or in whom laparoscopic surgery was converted to open access during the operation due to complications.

Open surgery is preferred over laparoscopy when the patient has had multiple prior abdominal or pelvic surgeries causing dense adhesions, when the liver is too enlarged to allow laparoscopic instrument placement, when significant bleeding occurs during laparoscopic procedure, or when the surgical team determines that direct visualization provides better safety for the patient.
Pre-operative assessment for open bariatric surgery includes:
All results are reviewed by the bariatric team before deciding on the surgical approach.
Open bariatric surgery is performed under general anesthesia. The surgeon makes a large midline incision in the abdomen, directly accesses the stomach and intestines, and performs the chosen weight loss procedure. The incision is then closed in layers. Total operating time ranges from 1.5 to 4 hours depending on the type of bariatric procedure selected.
The open bariatric surgery procedure involves:
Recovery from open bariatric surgery takes 4 to 8 weeks. Hospital stay is typically 3 to 5 days. Patients follow a gradual dietary progression from liquids to pureed, soft, and then solid foods over 4 to 6 weeks. Lifelong vitamin and mineral supplementation is mandatory. Activity restrictions are maintained for 4 to 6 weeks and follow-up visits are scheduled regularly.
Potential complications of open bariatric surgery include:
Open bariatric surgery carries slightly higher risks than laparoscopic approaches, including longer recovery and greater blood loss. However, it remains the preferred option when laparoscopic surgery is not feasible due to prior surgeries or patient anatomy.
Recovery from open bariatric surgery typically takes 4 to 8 weeks. Patients stay in hospital for 3 to 5 days. A gradual dietary progression from liquids to soft and then solid foods is followed. Lifelong nutritional supplements are required.
Yes, lifelong vitamin and mineral supplements are necessary after bariatric surgery. This includes iron, calcium, vitamin D, vitamin B12, and a daily multivitamin to prevent nutritional deficiencies.
Open bariatric surgery has a high success rate for long-term weight loss. Most patients lose 50 to 70 percent of excess weight within 2 years. Success depends on adherence to dietary and exercise guidelines post-surgery.
