Transanal Minimally Invasive Proctectomy With Two-Stage Turnbull-Cutait Pull-Through Coloanal Anastomosis for Iatrogenic Rectourethral Fistulas.

INTRODUCTION: Rectourethral fistula is an uncommon pathology, usually iatrogenic, occurring as a complication of surgical or ablative treatments for prostate or rectal cancer. Among other surgical techniques, restorative ultralow rectal anterior resection may be an option of last resort to achieve fistula closure avoiding the need for a permanent stoma. This article aims to describe a transanal minimally invasive-assisted Turnbull-Cutait technique for radiated rectourethral fistulas with a complementary video. TECHNIQUE: Turnbull-Cutait pull-through with delayed coloanal anastomosis technique with a proctectomy by transanal minimally invasive surgery and loop ileostomy was performed in 3 patients who developed delayed rectourethral fistula after prostate cancer treatment. Ileostomy was reversed after fistula closure confirmation. RESULTS: The first patient had brachytherapy with no surgery. The second patient had radical prostatectomy and adjuvant radiotherapy, developing the fistula after a pelvic abscess drained transrectally. The third patient underwent prostatectomy and brachytherapy, developing the fistula after transanal endoscopic microsurgery resection of a rectal villous polyp. Surgical intervention and postoperative recovery was uneventful. Fistula closure was confirmed in the 3 cases, and all ileostomies were closed without further recurrence at follow-up. CONCLUSIONS: Transanal minimally invasive proctectomy-assisted Turnbull-Cutait procedure for the treatment of rectourethral fistula is a new combination of already existing techniques, enabling the creation of safe colorectal anastomosis in high-risk cases. Given the difficulty obtaining healing with sphincter preservation in cases of postradiation rectourethral fistula, this technique aids in fistula closure and restoration of the intestinal continuity, and potentially represents an added resource in the surgical armamentarium for this challenging pathology.

How can we utilize local excision to help, not harm, geriatric patients with rectal cancer?

A majority of the morbidity and mortality burden of rectal cancer is distributed within the geriatric age group. Current surgical and medical treatment modalities pose significant challenges in treating complications specifically in the already pre-disposed senior population with baseline dysfunction. This chapter reviews the work-up, management, current data and oncologic outcomes of treating rectal cancer in the senior adult.
