A prospective study of assessment of prognostic factors in early and late wound dehiscence in midline vertical incision

Abstract

Background: Wound dehiscence is separation of some or all layers of incision. It may be partial or complete. It is called as complete when all layers of the abdominal wall have been separated with or without evisceration of viscous. The study aims to find out and record the prognostic factors for wound dehiscence in vertical midline laparotomy.Methods: This was a prospective study in 1400 laparotomies that developed wound dehiscence operated in Gandhi Medical College, Bhopal from august 2017 to august 2019. All the patients with burst abdomen operated during emergency or elective setting by midline vertical laparotomy were included.Results: Wound dehiscence was most common in 51-60 years age group (26%). Majority patients were males (62%). Emergency laparotomy showed maximum incidence (71%). Bursts were seen mostly during 6th to 10th postoperative day. 78% patients presented as partial wound dehiscence and remaining as complete wound dehiscence. 46% presented as early wound dehiscence (7 days).Conclusions: Post laparotomy wound dehiscence has multifactor etiology. Respiratory infections, anemia, and hypoproteinaemia are the contributing factors. Improper haemostasis during surgery and poor surgical technique are the predisposing factors.
