Gastrointestinal complications associated with pelvic exenteration.

J W Orr, H M Shingleton, K D Hatch

    American Journal of Obstetrics and Gynecology
    |February 1, 1983
    PubMed
    Summary

    Pelvic exenteration surgery can lead to gastrointestinal complications, especially when small bowel anastomosis is involved in previously irradiated areas. Surgical modifications significantly reduced these risks, improving patient outcomes.

    Area of Science:

    • Gynecologic Oncology
    • Surgical Gastroenterology

    Background:

    • Pelvic exenteration is a radical surgical procedure for advanced pelvic malignancies.
    • Gastrointestinal complications are a significant cause of morbidity following pelvic exenteration.

    Purpose of the Study:

    • To analyze the incidence and causes of gastrointestinal complications after pelvic exenteration.
    • To evaluate the impact of surgical modifications on reducing these complications.

    Main Methods:

    • Retrospective review of 125 pelvic exenterations performed between 1969 and 1981.
    • Analysis of reoperation indications, focusing on gastrointestinal complications.
    • Comparison of complication rates before and after implementing specific surgical techniques.

    Main Results:

    Related Experiment Videos

    • Gastrointestinal complications necessitated reoperation in 60% of cases, primarily linked to anastomosis in irradiated small bowel.
    • Preoperative factors had minimal impact on complication rates.
    • New techniques, including colon conduit, omental pedicle, and hyperalimentation, reduced small bowel obstruction/fistula to 2.2%.
    • Altered surgical techniques decreased rectovaginal fistula rates to 5.3%.

    Conclusions:

    • Anastomosis in previously irradiated small bowel is a major risk factor for gastrointestinal complications post-pelvic exenteration.
    • Surgical technique modifications are crucial for minimizing morbidity, specifically small bowel obstruction, fistula, and rectovaginal fistula.
