Objective: Post-laparotomy wound dehiscence, evantration and evisceration are important complications leading to an increase in both morbidity and mortality. Incisional hernias are frequently observed following abdominal surgeries and their occurrence is related to various local and systemic factors. This study aims to analyze the factors affecting wound healing by investigating the parameters that may cause wound dehiscence, incisional hernia, sinus formation and chronic incisional pain.
Material and Methods:The records of 265 patients who underwent major abdominal surgery were analyzed. The data on patient characteristics, medication, surgical procedure type, type of suture and surgical instruments used and complications were recorded. The patients were followed up with respect to sinus formation, incisional hernia occurrence and presence of chronic incision pain. Statistical analysis was performed using SPSS 10.00 program. The groups were compared via chi-square tests. Significance was determined as p<0.05. Multi-variate analysis was done by forward logistic regression analysis.Results: 115 (43.4%) patients were female and 150 (56.6%) were male. Ninety-four (35.5%) patients were under 50 years old and 171 (64.5%) were older than 50 years. The median follow-up period was 28 months (0-48). Factors affecting wound dehiscence were found to be; creation of an ostomy (p=0.002), postoperative pulmonary problems (p=0.001) and wound infection (p=0.001). Factors leading to incisional hernia were; incision type (p=0.002), formation of an ostomy (p=0.002), postoperative bowel obstruction (p=0.027), postoperative pulmonary problems (p=0.017) and wound infection (p=0.011).
Conclusion:Awareness of the factors causing wound dehiscence and incisional hernia in abdominal surgery, means of intervention to the risk factors and taking relevant measures may prevent complications. Surgical complications that occur in the postoperative period are especially related to wound healing problems.Key Words: Abdominal surgery, wound dehiscence, incisional hernia, sinus formation, chronic incisional pain
INTRODUCTIONWound dehiscence after laparotomy can manifest with different presentations varying from simple skin detachment to evisceration and eventration, leading to an increase in surgical mortality and morbidity, as well as increase in length of hospital stay and loss of work force.Anterior abdominal wall incision hernia that can be seen in the long term is also one of the common surgical complications. Known as postoperative hernia or incisional hernia, it is thought to result from insufficient closure of the fascia and/or poor healing. Factors causing chronic or prolonged postoperative intra-abdominal pressure increase and those affecting wound healing contribute to its development. The incidence of incisional hernias vary from 2% to 20% in different sources, and in addition to pain and impairment in quality of life it may also cause significant complications (1, 2). It has been reported that incarceration may occur in a rate of 15%, ...
