"EFFECT OF DEFECT SIZE ON OPERATIVE REPAIR IN INCISIONAL HERNIA"

ABSTRACT Background: Incisional hernia repair is a commonly performed surgical procedure; however, analysis of patient outcomes based on hernia defect size remains limited. This study aims to identify differences in operative techniques and postoperative complications associated with hernia defect size. Methods: A comparative study was conducted of all patients undergoing open incisional hernia repair at JSS Hospital, Mysuru, from May 2023 to November 2024. Patient demographics and operative data were collected. Continuous variables are presented as means, while categorical variables are expressed as percentages. Differences between groups, divided by defect size (<10 cm and >10 cm), were analysed using the chi-square test. Results: A total of 30 patients underwent open incisional hernia repair with intraoperative measurement of defect size. Component separation was used more frequently in patients with defect sizes greater than 10 cm. Mesh was utilized in all cases, predominantly placed in the sublay position. Mean hospital length of stay increased with defect size. Larger defect size (>10 cm) was significantly associated with increased postoperative complications, including seroma formation, surgical site infection. Conclusions: Hernia defect size significantly influences the operative approach and postoperative outcomes in incisional hernia repair. Larger defects (>10 cm) are more likely to require component separation and are associated with a higher risk of complications.
