AbstractBackground: Incisional hernia is a common problem in our surgical practice and it poses a challenge due to its high incidence of complications like seroma and surgical site infection (SSI).
The objective of this study is to assess the contribution of diathermy to postoperative seroma formation and wound complications in incisional hernia surgery and also to assess other predictors for wound complications including comorbidities, personal and hernia characteristics.
Patients and Methods: This is a prospective case series study comparing two types of flap dissection in cases of open incisional hernia mesh repair. Sixty patients randomized in to two groups of abdominal flap dissection, one group with electro cautery dissection and other group with sharp dissection by scissors and knife. Surgical procedure was the same between the two groups. Primary outcome measures were postoperative seroma, SSI and wound dehiscence.
Results: There was no significant difference in seroma formation (p=0.738), SSI rate (p=0.641) and wound dehiscence rate (p=0.150) between the electro cautery group and the sharp dissection group. The use of cautery leads to reduction in the intraoperative blood loss (p<0.0001) and operative time (p<0.0001). The relation between body mass index (BMI), diabetes mellitus (DM), hernia length, width and postoperative seroma was highly significant (p=0.002, 0.034, 0.002, Conclusions: The use of cautery instead of scissors during flap dissection does not result in increased postoperative wound complications in incisional hernia patients. The use of cautery lead to reduction in the operative time and intraoperative blood loss. The relation between DM, BMI, hernia defect size and increased rate of wound complications was significant.
