Magnitude of Abdominal Wound Dehiscence and Associated Factors of Patients Who Underwent Abdominal Operation at St. Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia

Abstract EN

Background.

Abdominal wound dehiscence (AWD) is the separation of different layers of an abdominal wound before complete healing has taken place.

It is a major cause of postoperative morbidity and mortality in sub-Saharan Africa including Ethiopia, and little is known about its prevalence and related factors in the study area.

Objectives.

The aim of this study is to assess the magnitude of abdominal wound dehiscence and related factors on patients operated at St.

Paul’s Hospital Millennium Medical College, Addis Ababa, Ethiopia.

Methods.

A hospital-based retrospective review of the chart was carried out by using the data covering three years (September 2014–September 2017) period.

Data were collected from hospital medical records of sampled patients such as operation room logbooks and individual patient medical records.

The collected data were checked for consistency, coded, and entered into SPSS version 20 for data processing and analysis.

Descriptive analysis was conducted, and tables and graphs and summary statistics were used to depict data.

Results.

A total of 41 patients developed abdominal wound dehiscence from among 4137 patients who underwent abdominal laparotomy in the hospital.

Among the patients, 51.2% were in the age range of 41 and above with mean age 29.8 (SD = 1.21) and 70.7% of them were male.

Abdominal wound dehiscence was more common in emergency patients (90%) and vertical incision was the most common type of incision.

Over half (58.5%) of the wound dehiscence occurred within 6–10 postoperative days.

The majority (95.2%) of dehisced patients underwent relaparotomy for the management of the wound dehiscence, and 48.8% of them were treated with tension suture during the second operation of abdominal closure.

Four of the patients (9.7%) died after the management of the second operation.

Conclusion.

The current study revealed that the overall magnitude of abdominal wound dehiscence in the study area was 0.99%.

Most of the dehiscence has occurred in male patients, and older age groups were highly affected than the younger ones.

Emergency admission is the most common form of admission identified in the study, and this signifies appropriate preoperative preparation of patients for an optimal outcome.

However, regarding the management outcome, 9.8% of patients died in our study within the institution after the second operation which is the high mortality rate.
