Figure 1. (A) The anvil of the stapler is inserted and secured by a 2-0 monofilament purse-string suture. The colon is opened longitudinally between the taenias beginning 2 cm proximal to the rim of the anvil. Lateral traction by stay sutures shows how the transverse coloplasty pouch is formed. (B) The colostomy is closed transversely by the first running suture (5-0 PDS). (C) The second running seromuscular suture line concludes the formation of the transverse coloplasty pouch, followed by the completion of the anastomosis.
