MA, Jessica; ZHANG, Brook; WU, Xian-rui  and  SHEN, Bo. Successful endoscopic treatment of fecalith blocking sinus in a patient with ileal pouch-anal anastomosis. J. Coloproctol. (Rio J.) [online]. 2014, vol.34, n.3, pp.181-184. ISSN 2317-6423.


Ulcerative colitis patients who underwent restorative proctocolectomy with ileal pouch-anal anastomosis can develop various mechanical complications. Among them is presacral sinus resulting from chronic anastomotic leak.


We present a symptomatic patient with a large fecalith blocking the sinus which was successfully treated with Doppler ultrasound guided endoscopic needle knife sinusotomy along with fecalith extraction.


A 67-year-old female presented with a 4-month history of perianal pain and urgency. Pouchocopy showed a 3-cm deep wide-mouthed anastomotic sinus, the orifice of which was blocked by a large hard fecalith. Removal of the fecalith using RothNet, Tripod, or Basket were made but failed. Then needle knife was applied to cut the orifice to enlarge the opening of the sinus. One month later, the patient returned and the fecalith was successfully removed with two Baskets and two Rothnets. Six months after fecalith extraction, pouchoscopy showed a compartalized distal pouch sinus with two cavities, which was treated by two sessions of Doppler ultrasound guided endoscopic needle knife sinusotomy. Six months following the treatment, the sinus was completed healed. The patient tolerated all procedures well without any complication.


Fecalith blocking pouch anastomotic sinus is a rare complication in patients with restorative proctocolectomy. In our case, this surgical complication was successfully treated with a carefully planned, stepwise endoscopy approach.
