Abstract

In colorectal surgery, eradicating the fistula and maintaining continence are still complex challenges for a colorectal surgeon. A minimally invasive method using a novel device was performed to consecutively treat 14 patients with anal fistula from August 2008 to November 2009. After a follow-up period of 36 months, 13 patients achieved successful closure of their fistula tracts, and recurrence occurred only in one patient. Recurrence was due to the delay of dressing change. No patient had interference with continence, and no major intra- and post-operative complications were identified. Using the novel device with invasive methods can be a promising alternative for managing anal fistulas.

Fig.1 Novel surgical instrument invented by Dr. Caoyuan Wang. 1, mini-electromotor; 2, positive spin button; 3, anti-spin button; 4, electrical outlet; 5, tool-holder; 6, mill.

Fig.2 A probe was gently inserted into the external opening and was removed from the anal canal through the internal opening. While the probe was in the fistula tract, a V-shaped incision was made at approximately 1.5 cm from the anal margin to ensure that the internal opening was completely eradicated.

Fig.3 Necrotic or granulation tissue was completely excised from the fistula tract by using the new device.

Fig.4 A typical case of patient, presenting a complicated anal fistula with two external orifices. The wound completely healed without obvious scarring six weeks after the surgery.
