Abstract
Purpose: Burst abdomen (BA) is a relevant complication after abdominal surgery that causes additional surgical procedures, prolonged hospital stays and long-term morbidity. Several underlying risk factors exist and have been characterized previously. Those risk factors consist of surgical and medical factors. Recently, CT-derived body composition is of rising interest and 3D reconstruction of the linea alba has been studied. The clinical significance of those parameters is not clear. We therefore performed an analysis of linea alba 3D reconstruction measurements and their prognostic significance on the development of BA.
Methods: An institutional data base of patients with post operative wound infections was assembled. The subgroup of patients with BA was compared to controls. If the patients had complete preoperative abdominal CT scans, their images were further analyzed and 3D reconstruction of the linea alba was performed. Subsequently, lineal alba was measured at predetermined positions. Those values were evaluated as risk factors for postoperative BA.
Results: A total of 72 patients with BA and 32 controls were eligible for the analysis. We found body mass index-related significant differences as well as sex related differences in linea alba width. Furthermore, BA patients had a significantly wider linea alba and longer sagitta compared to controls. In the multivariate analysis of linea alba measurements and clinical parameters, the length of the sagitta was significantly associated with the risk of BA (OR 1.266; 95% CI 1.011-1.585; p = 0.04).
Conclusion: In this study of 3D reconstruction of the linea alba from routine CT scans, we could show that a longer sagitta was associated with an increased risk of postoperative BA.
期刊介绍：
Hernia was founded in 1997 by Jean P. Chevrel with the purpose of promoting clinical studies and basic research as they apply to groin hernias and the abdominal wall . Since that time, a true revolution in the field of hernia studies has transformed the field from a ”simple” disease to one that is very specialized. While the majority of surgeries for primary inguinal and abdominal wall hernia are performed in hospitals worldwide, complex situations such as multi recurrences, complications, abdominal wall reconstructions and others are being studied and treated in specialist centers. As a result, major institutions and societies are creating specific parameters and criteria to better address the complexities of hernia surgery.
Hernia is a journal written by surgeons who have made abdominal wall surgery their specific field of interest, but we will consider publishing content from any surgeon who wishes to improve the science of this field. The Journal aims to ensure that hernia surgery is safer and easier for surgeons as well as patients, and provides a forum to all surgeons in the exchange of new ideas, results, and important research that is the basis of professional activity.
