Transanal intersphincteric approach combined with Kangfuxin enema for treating anastomotic leakage after low anterior resection: Three case reports

Figure 3 Case 2. A: Abdominal computed tomography scan revealed a discontinuous anastomosis and the formation of an anastomotic leak; B: Subsequently after transanal opening of the intersphincteric space, an abdominal computed tomography scan showed that the anastomosis was continuous with no obvious gap; C: The colonoscopy confirmed that the anastomotic defect was healed. Arrows: Healing site of the anastomotic fistula opening.
