Background: Transverse colostomy is commonly performed to create temporary stoma in
rectal cancer patients after neoadjuvant chemoradiotherapy. Conventional methods are either
difficult to implement or to care for. To resolve these problems, we herein describe a modified
transverse colostomy method.
Material and Methods: Two sutures of peritoneum were made as “bridges” to support the stoma.
Absorbable sutures were utilized to reinforce the stoma. Once the stoma was created, the stoma bag
was immediately placed on the skin. 120 patients who received conventional or modified transverse
colostomy between 2008 and 2014 were selected. Then, the two groups of patients were compared
for stoma-related complications.
Results: The operation time of stoma construction was 34±10 minutes for the conventional method
and 28±7 minutes for the modified method (P= 0.009). There were no significant differences
between the two groups with respect to postoperative bleeding, bowel obstruction or stoma
retraction. Patients with conventional transverse colostomy were remarkably more likely to
experience parastoma hernia (P= 0.048) and stoma prolapse (P= 0.038).
Conclusion: In comparison with conventional methods, the modified transverse colostomy is a safe
and effective diverting technique. It can be readily performed by all kinds of surgeons, especially
those in underdeveloped areas. The technique represents a preferred method for constructing
temporary stoma in rectal cancer patients treated with neoadjuvant chemoradiotherapy.
