Watch this detailed video on Sleeve Gastrectomy in a patient previously operated for Ventral Hernia. This educational video demonstrates the surgical techniques, challenges, and step-by-step approach for safely performing laparoscopic sleeve gastrectomy in patients with prior ventral hernia surgery.

Generally it should not be a problem to have a sleeve after incisional hernia repair, even with mesh. You do not need to worry about the insufflation of the abdomen stretching the mesh if you go through palmer's point. All laparoscopic incisions are small and do not disrupt the integrity of the mesh. The only incision that is a little larger is the one that the resected stomach is removed through. Ideally you want to do the sleeve laparoscopically. Yes, there will be a lot of adhesions, but an experienced laparoscopic bariatric surgeon can get it done with the laparoscope. The mesh can be re-sewn and it will heal fine. It is hard to say for sure without knowing where on your abdominal wall the mesh was placed, but I have operated on numerous patients with prior hernia repairs and it isn't a challenge that can't be overcome. If the hernia was from a prior C-section, meaning lower on your abdominal wall, then the laparoscopic port sites for a VSG should not interfere.

Obesity has become a global epidemic, with bariatric surgery emerging as the most effective long-term treatment for morbid obesity and its associated comorbidities. Among the available procedures, Laparoscopic Sleeve Gastrectomy (LSG) has gained widespread popularity due to its efficacy, simplicity, and relatively lower complication rate. However, performing sleeve gastrectomy in patients with a history of ventral hernia repair presents unique challenges for bariatric surgeons. Adhesions, altered anatomy, and the presence of mesh can complicate the procedure and increase the risk of intraoperative and postoperative complications.

Understanding the Challenge
A ventral hernia is a defect in the abdominal wall through which abdominal contents may protrude. Surgical repair may involve direct suture closure or placement of a synthetic mesh to reinforce the abdominal wall. Patients with previous ventral hernia repairs often develop intra-abdominal adhesions, which can obscure normal anatomy, make trocar placement difficult, and increase the risk of bowel injury during laparoscopic procedures. Moreover, the presence of mesh can complicate port placement and dissection near the abdominal wall.

Preoperative Evaluation
Thorough preoperative evaluation is crucial in patients with a history of ventral hernia repair:

1. Detailed Surgical History: Information about the type of hernia repair, mesh type, location, and any previous complications.

2. Imaging Studies: CT scan of the abdomen may help assess the position of mesh, detect adhesions, and identify residual or recurrent hernias.

3. Assessment of Comorbidities: Obesity-related conditions like diabetes, hypertension, and sleep apnea should be optimized before surgery.

4. Patient Counseling: Patients should be informed about the potential increased risk of operative difficulty and complications.

Surgical Considerations

1. Port Placement: Traditional laparoscopic port sites may not be feasible due to previous hernia repair or mesh placement. Surgeons may need to use alternative entry points, such as Palmer’s point, to avoid injuring the bowel or mesh.

2. Adhesiolysis: Careful and meticulous dissection is essential to release adhesions while minimizing the risk of bowel injury. The use of energy devices and blunt dissection helps reduce trauma.

3. Mesh Management: If adhesions involve the mesh, surgeons must avoid disturbing it unnecessarily to prevent infection or mesh displacement. In rare cases, partial mesh removal may be required if it interferes with the sleeve procedure.

4. Sleeve Gastrectomy Technique: Once safe access is established, sleeve gastrectomy proceeds similarly to standard cases. Attention must be paid to maintaining hemostasis and avoiding traction on adhesed tissues.

5. Conversion Threshold: Surgeons should maintain a low threshold for conversion to open surgery if safe laparoscopic access is compromised.

Postoperative Care
Patients with previous ventral hernia repair may be at higher risk for certain complications:

• Wound-related complications: Risk of infection or hernia recurrence at previous repair sites.

• Gastrointestinal complications: Leak, bleeding, or obstruction may be more challenging to manage due to adhesions.

• Pain Management: Adequate analgesia and early mobilization are essential to reduce pulmonary and thromboembolic complications.

Outcomes and Prognosis
Recent studies suggest that sleeve gastrectomy is feasible and safe in patients with previous ventral hernia repair when performed by experienced bariatric surgeons. Although operative time may be longer and adhesiolysis increases technical difficulty, complication rates are comparable to standard sleeve gastrectomy in most series. Careful patient selection, preoperative planning, and meticulous surgical technique are key to successful outcomes.

Conclusion
Performing sleeve gastrectomy in patients with prior ventral hernia repair requires careful planning, advanced laparoscopic skills, and individualized surgical strategies. While adhesions and mesh presence add complexity, with proper precautions, sleeve gastrectomy remains a safe and effective procedure for weight loss and improvement of obesity-related comorbidities in this challenging patient population. Collaboration between bariatric and hernia specialists can further optimize patient outcomes.
