A 74-year-old man was referred to our department for endoscopic evaluation and treatment of a rectovesical fistula. He had undergone prostatectomy for early prostate cancer 2 weeks previously. Postoperatively, he had developed pneumaturia and dysuria; computed tomography (CT) had revealed a rectovesical fistula.
At colonoscopy, a well-circumscribed opening of a fistula tract was seen in the anterior rectal wall, located 2 cm beyond the linea dentata ([Fig. 1]). The edges of the fistula were cauterized with argon plasma coagulation to stimulate an inflammatory reaction and local collagen synthesis. A 2-mL syringe containing 1 mL n-2-butyl cyanoacrylate (Histoacryl; B. Braun, Melsungen, Germany) and 1 mL Lipiodol was prepared and the glue/Lipiodol mix was injected via a 23-G variceal needle in aliquots of 0.5 mL at four sites of the wall of the fistula, followed by a flush of Lipiodol equivalent in volume to the dead space of the needle. The margins of the fistula orifice were brought into contact and closed with endoclips (HX-600-900; Olympus, Athens, Greece; [Fig. 2]). After endoscopic intervention, the patient was treated with parenteral nutrition and antibiotics. His symptoms completely resolved and he was discharged 7 days after the procedure. A follow-up endoscopy performed 1 month later revealed that the lesion was well healed ([Fig. 3]). He remains asymptomatic 6 months post-procedure.
Rectal injury after radical prostatectomy with subsequent formation of rectovesical fistula has an incidence of 1 – 11 % [1]. York–Mason, modified York–Mason and less invasive repair methods, which include laparoscopic and robotic-assisted techniques, have been reported as successful treatment modalities for rectovesical fistulas [2] [3].
We wish to emphasize the use of the combination of endoclips plus n-2-butyl cyanoacrylate injection in the treatment of gastrointestinal fistulas. To our knowledge, the present case is the first report of a rectovesical fistula that was successfully treated with injection of glue plus endoclipping.
