Quality of life and abdominal wall functionality after abdominal wall reconstruction: A prospective single center follow-up study

BACKGROUND: Fascial breakdown with the occurrence of an incisional hernia (IH) is an important and challenging complication of any laparotomy. For a long time, the success of the abdominal wall reconstruction (AWR) was measured only from the surgeon's perspective by defining outcome measures such as wound morbidity and recurrence. The understanding that complete recovery is difficult to assess without considering patients has shifted the paradigm of optimal outcomes to Patient Reported Outcome Measures (PROMS) and Quality of Life (QoL), which are pivotal to evaluate the success and efficacy of AWR. METHODS: We conducted a prospective follow-up study of 91 patients undergoing mesh-augmented abdominal wall reconstruction for primary or recurrent incisional hernia between January 2021 and December 2023. Demographic data, comorbidities, and hernia characteristics were recorded. All patients were evaluated preoperatively by a native abdomino-pelvic CT scan to assess the characteristics of hernia (length, width, surface, and volume of the incisional hernia sac and of peritoneal cavity), the presence of mesh (if previously inserted), and abdominal wall muscles status. All intervention were performed by the same surgical team according to the techniques described by Rives - Stoppa (RS), Ramirez (ACS), and Novitsky (PCS). Abdominal wall function was assessed using trunk raising (TR) and double leg lowering (DLL) measurements performed preoperatively, 1 month, 6 months, and 1 year postoperatively. At the same time, pre- and post-operative quality of life was analysed using the EQ-5D score. RESULTS: with Yates continuity correction for two degrees of liberty = 46.04; p < 0.00001). CONCLUSION: Our results suggest that patients can expect to see a significant overall improvement in all five components of QoL measured with the help of Eq. 5D questionnaire. This improvement is dependent by hernia size, and some individual patient's factors (diabetes, cardiovascular diseases, and age over 60 years).
