Brief Summary

Brief Study Description This prospective observational study evaluates the use of preoperative botulinum toxin A as part of a structured clinical pathway for patients undergoing elective repair of complex midline incisional hernias. Botulinum toxin A is administered before surgery to temporarily relax the abdominal wall muscles, with the aim of improving abdominal wall flexibility and facilitating closure of the hernia without the need for more extensive surgical techniques. The study collects clinical, radiological, and postoperative outcome data to assess surgical feasibility, complications, and early recurrence. The overall goal is to better understand how preoperative muscle relaxation may support safer and more effective abdominal wall reconstruction.

Outcome Measures

Primary Outcomes (1)

  • Rate of fascial closure without transversus abdominis release

    The proportion of patients in whom midline fascial closure is achieved using the Rives-Stoppa technique without the need for transversus abdominis release during elective repair of complex midline incisional hernias following preoperative botulinum toxin A administration.

    During surgery (index procedure)

Secondary Outcomes (4)

  • Radiological changes in abdominal wall morphology

    Baseline and 5 weeks after botulinum toxin A injection

  • Postoperative complications

    Up to 30 days after surgery

  • Length of hospital stay

    Immediately after surgery

  • Early hernia recurrence

    Up to 12 months after surgery

Study Arms (1)

Patients with complex midline incisional hernia

his cohort includes adult patients with complex midline incisional hernias undergoing elective surgical repair within a standardized clinical pathway that incorporates preoperative botulinum toxin A administration. Participants are prospectively followed to collect clinical, radiological, surgical, and postoperative outcome data as part of routine clinical care.

Individual participant data will not be shared. This study is a single-center prospective observational cohort with a limited sample size, and the collected clinical and imaging data may contain potentially identifiable information. No formal data-sharing plan was included in the original study protocol, and no approval for external data sharing was obtained from the local ethics committee. Aggregate data are reported in publications, and additional information may be considered upon reasonable request and subject to institutional and ethical approval.
