Reoperation rate was 5,2% (2 patients), one due to a bowel obstruction, being performed by conventional selleckchem Veliparib laparoscopy, identifying the drain as the cause of this problem, since it entraps the small bowel. The other case was performed by open approach, and it was due to a leak of the anastomosis. Total morbidity was 13%: there were one leak (2,6%), one bowel occlusion (2,6%), one paralytic ileus (2,6%), and 2 wound infections (5,2%). Long-term follow up showed one incisional hernia (2,6%). Histological exams of the specimens showed that the oncological criteria, related to number of lymph node (100% patients more of 12 lymph nodes, ranges 12�C27) and resection margin (more than 5cm), were preserved. 4. Discussion We report our initial series of single-port access right hemicolectomy with total intracorporeal anastomosis without any additional trocars.

Single-port access surgery is the result of the continuous search for increasing less invasive approaches. This technique has been possible thanks to the development of flexible instruments and trocars which enables the introduction of several instruments [11]. The main goal of this novel approach is to follow the same steps and principles of standard laparoscopic right hemicolectomy achieving the same oncological results. In fact this laparoscopic approach has been demonstrated to be as effective as conventional surgery for the treatment of carcinoma of colon [1, 2].

Single-port access surgery tries to obtain certain additional benefits in comparison to laparoscopic approach, such as better cosmetic results and potential minimization of postoperative pain, apart from the advantages associated to less traumatism to the abdominal wall, avoiding possible complications associated to the use of additional trocars, such as abdominal wall bleeding or hernias at the site of these additional lateral trocars. But these theoretical advantages still have to be demonstrated in prospective randomized trials. A review of the literature starts showing different series on single-port right hemicolectomy [12�C18]. All series and cases reported were performed with extracorporeal anastomosis, but in our series both the resection of the specimen and subsequent anastomosis were intracorporeal, what could add different advantages to the procedure.

In fact, the specimen was removed from the abdominal cavity in a 15mm bag, avoiding the necessity to enlarge the incision, to carry out the extracorporeal anastomosis, and also possible unnecessary tractions of the pedicle Entinostat of the transverse colon, where the anastomosis was performed. Intracorporeal ileocolic anastomosis can be performed safely and effectively, although this technique needs to be performed by expert surgeons with experience in this type of anastomosis and with skills in single-port approach, what could increase the learning curve.
