Defecation disorder after anterior pelvic exenteration

Area of Science:

• Gynecologic oncology
• Surgical oncology
• Colorectal surgery

Background:

• Anterior pelvic exenteration aims to preserve rectal function but may cause persistent postoperative defecation disorders.
• Frequent, watery stools are observed post-anterior pelvic exenteration, with limited existing literature on this specific complication in gynecological cancer patients.

Purpose of the Study:

• To evaluate the defecation status and identify factors associated with persistent postoperative defecation disorders after anterior pelvic exenteration for gynecological malignancies.

Main Methods:

• Retrospective analysis of 16 patients undergoing anterior pelvic exenteration between 2012-2022.
• Comparison with 132 radical hysterectomy and 13 radical cystectomy cases.
• Evaluation of postoperative defecation frequency and stool form (Bristol Stool Form Scale).

Main Results:

• Patients undergoing laparoscopic anterior pelvic exenteration with rectal mobilization experienced more frequent, watery stools compared to radical hysterectomy and radical cystectomy.
• Laparoscopy and rectal mobilization were identified as potential causes for increased defecation frequency.
• No significant difference in defecation frequency was noted between laparotomic procedures.

Conclusions:

• Anterior pelvic exenteration, especially with laparoscopic techniques and rectal mobilization, is associated with postoperative frequent watery stools.
• Prospective studies are necessary to confirm these findings in larger patient cohorts.
