Figure 3

Operative illustrations showing single-port laparoscopic colectomy with transanal specimen extraction (TASE). After dissection, both ends of the tumor-bearing segment were bound with tape, and the proximal end was divided by End-GIA. A The distal end of the tumor-bearing segment was identified. The white arrow indicates the direction to the rectum. The red arrow indicates the tumor-bearing segment. The dotted line indicates the planed resection line. B The tumor-bearing segment was completely resected by dividing the distal end. C An anal trocar was entered into the pelvic cavity via the anus. D An anvil with an anchor suture was entered into the pelvic cavity through the anal trocar. E The anvil was introduced into the remaining colon and was fixed by purse-string suture. F, G Thereafter, the specimen was retrieved through the anal trocar. H Lastly, end-to-end colorectal anastomosis was performed with a transanally inserted circular stapler (EEA 28 mm or 31 mm; Ethicon, USA).
