Over-the-scope-clipping system for anastomotic leak after colorectal surgery: Report of two cases

Figure 1 Anastomosis after low anterior resection. A: Colonoscopy shows breakdown at the anastomotic ring; B: Breakdown site has been closed by the over-the-scope-clipping system.

Figure 2 Contrast radiography after low anterior resection. A: Large abscess is seen outside the bowel; B: Breakdown site has been closed by the over-the-scope-clipping (OTSC) system; C: Abscess has shrunk two days after closure by the OTSC system.

Figure 3 Contrast radiography after sigmoidectomy. A minor leak is shown.

Figure 4 Anastomosis after sigmoidectomy. A: Colonoscopy shows a reddened area at the anastomosis; B: Reddened area has been closed by the over-the-scope-clipping system.
