Comparative study of repair of incisional hernia.

Repair of incisional hernias was compared with four different techniques in 55 patients to determine the best method of repair with least chance of recurrence. The maximum incidence of incisional hernia was seen in 30-39 years age group and was most frequently seen after gynaecological surgery (37 cases). Forty eight (88%) patients were operated in emergency by trainee surgeons. Most hernias occurred within one year after surgery and the herniation of lower mid line incision was more frequent (70.9% cases). History of wound infection of previous surgery was recorded in 45.5% of cases which appeared to be the important risk factor in causation of incisional hernia. It was also observed that simple repair of incisional hernia was associated with a high recurrence than that where synthetic mesh was used in repair where no recurrence was recorded.
