Preoperative Botulinum Toxin Injection for Complex Abdominal Wall Hernia Repair

Abstract

Introduction: Due to their higher rates of morbidity and recurrence, complex abdominal wall hernias provide a difficult clinical dilemma. Botulinum toxin injection has been suggested as a feasible treatment option to ease patients' tense muscles and promote primary fascial closure. This study focus on how well preoperative botulinum toxin injections worked for patients with complicated abdominal wall hernias. Methodology: The patients in this retrospective study had complex abdominal wall hernias. Between January 2021 and December 2022, they had received preoperative botulinum toxin injections for those hernias. Age, gender, the extent of the transverse hernia defects both before and after the procedure, loss of domain, and muscle length, all were the study's variables. The data were analyzed using comparative analysis and paired t-tests. Results: The study involved 8 patients in all, with an average age of 53.38 ± 12.56 years. The mean fascial defect size before injection was 13.14 ± 4.58 cm, while the mean fascial defect size after injection was 11.84 ± 4.07 cm. Following the Botox injection, there was a statistically significant decrease in the size of the transverse hernia defect (p 0.001). The mean loss of domain before the surgery was 18.46 ± 11.96%, while the mean loss of domain after the 7.21%. Following the Botox injection, there was a statistically significant decrease in loss of domain (p 0.05). In 7 individuals, primary fascial closure was accomplished (87.5%). Both surgical and chemical components had no significant side effects. Conclusion: In individuals with complicated abdominal wall hernias, preoperative botulinum toxin injection is an efficient and secure method for lowering muscle tension and attaining primary fascial closure. it is challenging to make firm judgments on the effectiveness of preoperative Botox injection for complex abdominal wall hernia repair in the absence of a control group. The results of the current study need to be confirmed by larger studies with longer follow-up times and a control group.
