Summary
Preoperative weight loss interventions before ventral hernia repair (VHR) did not significantly alter hernia recurrence or complication rates in obese patients. Further prospective studies are needed to define the optimal role of weight optimization in VHR outcomes.
Area of Science:
- Surgical Oncology
- Bariatric Surgery
- Hernia Repair
Background:
- Obesity increases ventral hernia risk and recurrence after repair.
- Metabolic issues in obesity can cause postoperative complications.
- Preoperative weight loss is common but lacks consensus for ventral hernia repair (VHR).
Approach:
- Meta-analysis of studies comparing obese patients with and without preoperative weight loss interventions before VHR.
- Searched PubMed, Scopus, and Cochrane Library databases.
- Assessed outcomes including hernia recurrence, seroma, hematoma, surgical site infection, and overall complications.
Key Points:
- No significant differences in hernia recurrence, seroma, hematoma, surgical site infection, or overall complications were found between groups.
- Subgroup analyses of bariatric surgery and weight loss also showed no significant differences in outcomes.
- Five studies with 465 patients were included in the meta-analysis.
Conclusions:
- Preoperative weight optimization did not impact key outcomes for ventral hernia repair in obese patients.
- Findings suggest similar rates of hernia recurrence and complications regardless of preoperative weight loss.
- Prospective research is necessary to establish the definitive role of preoperative optimization in obese patients undergoing VHR.

Patients with hypertrophic cardiomyopathy (HCM) and left ventricular outflow tract (LVOT) obstruction who remain symptomatic despite optimal medical therapy may undergo a septal myectomy (Morrow procedure). This procedure involves excising a portion of the hypertrophied septum below the aortic valve using a heart-lung machine to improve blood flow through the LVOT. Effective preoperative and postoperative nursing management ensures successful patient outcomes, minimizes complications, and...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
