The evaluation of risk factors in fascia dehiscence after abdominal surgeries

Abstract

Background: Despite the advances in surgical techniques and risk control practices in recent years, open wounds following abdominal laparotomy still have a high prevalence. The purpose of this study is to investigate the risk factors of fascia dehiscence (FD) in abdominal surgery patients. Methods: In this observational study, a total of 60 emergency and elective laparotomy patients were enrolled. For all patients, with (treatment) or without (control) wound dehiscence, a checklist was used to extract data from medical records regarding underlying diseases, suturing method, emergency or elective surgical procedure, duration of surgery less than 180 min, intraoperative bleeding, wound closure method, hernia repair, age, sex, smoking history, comorbidities, type of surgery, colostomy placement, wound complications, re-operation, mortality, wound complications including wound infection, wound dehiscence, incisional hernia, and anastomotic leak, and preoperative readiness assessments such as laboratory tests including C-reactive protein (CRP), Albumin (Alb), etc., were completed, and then comparisons were made. Results: Patients were examined in two groups: 14 patients (70%) in wound dehiscence with age 40–60 and 6 patients (30%) in non-wound dehiscence with age 60–75. Eight patients (40%) underwent elective surgery, and 12 patients (60%) underwent emergency surgery (P=0.2). Fourteen patients (70%) experienced mortality (P<0.001) and 13 patients (65%) had Alb less than 3 (P<0.001). Fourteen patients (70%) had drain installation (P=0.02). It was determined that the increase in CRP levels (compared to pre-dehiscence levels) was observed in 17 out of 20 cases, with the highest difference being CRP=91 and an average increase of 30. None of the patients suspected of anastomotic leakage were confirmed to have it. Dehiscence was typically diagnosed between the 4th and 7th days post-surgery. The colon and rectum were significantly more associated with dehiscence, while the stomach had the lowest association among surgical sites. Conclusion: Based on this study, FD is more common in patients treated in the emergency room than in elective procedures. Mortality occurred more in patients with FD, and there is a significant relationship between FD with albumin less than 3 and drain placement.
