Background: Single-Incision Laparoscopic Surgery(SILS) right hemicolectomy is a safe and feasible procedure in benign and malignancy colon diseases. But SILS is still very situational, and requires more effort from the surgeon. We report a novel surgical technique of single-incision laparoscopic surgery with one assist port (SILS-One) which could be performed more easier and comfortable than conventional SILS right hemicolectomy.

Methods: A periumbilical 3-cm longitudinal skin incision was made and carried down to the fascia layer. Three 5-mm trocars were placed through the incision and another 5-mm trocars was placed in the right lower quadrant. The inclusion criteria was lesions located at right side colon. Cases of obstruction or perforation that required emergent operation were excluded. The patient’s age, gender, surgical indication, intraoperative, postoperative and pathology were assessed.

Result: A total of 62 patients (30 male and 32 female) underwent single-incision laparoscopic surgery with one assist port (SILS-One) right hemicolectomy. Surgical indication included colon cancer (48 cases), colon polyps (7 cases), diverticulitis ( 5 cases), appendiceal carcinoid ( 1 cases), appendiceal mucinous adenocarcinoma ( 1 cases). The mean age of patients was 62.23 years old, with a mean body mass index (BMI) of 23.63 kg/m2. The mean operative time and intraoperative blood loss was 168.92 minutes and 48.46 ml. The mean length of hospital stay was 6.26 days, mean length of specimen was 28.17 cm, and mean numbers of harvested lymph nodes were 25.63. There were no conversions to open surgery during any of the cases and no morbidity or mortality was associated with this technique.

Conclusion: Compared with conventional SILS right hemicolectomy, the minimal invasive laparoscopic surgery method, so-called SILS-One, has better surgical triangulation traction and equal benefit in wound problems even cosmetic advantage. Operation can be performed more comfortably and smoothly with adding one port inserted in the right lower quadrant.
