Long-Term Follow-Up Results of Single Port Laparoscopic Right Hemicolectomy

Abstract

Objectives: evaluation of feasibility, safety, and outcomes of single port laparoscopic surgery (SPLS) for right hemicolectomy. Method and material: Prospective study of 84 patients suffering from right colon cancer who underwent SPLS between Decem-ber 2010 and December 2016 and were followed up until December 2017 in Hue Central Hospital. Results: Mean age of patients was 56.3 ±16.2 (25-87) years, fifty-five (64,28%) were males. Mean BMI was 24.2±5.3kg/m2. mean ASA score for all patients was 2.7 (1-3). Ten cases (11.9%) required additional ports in which 6 were finally converted to open surgery. There were no deaths as well as intraoperative complications. Mean tumor size was 4.4±3.6 (3-8 cm). For successful operated group with SPLS, mean operation time was 135.5±23.2 minutes. Blood loss was 54±22 ml. Mean incisional length (including extension for extraction) was 4.6±3.5cm. Mean lymph nodes harvest was 14.2±0.8. Stage I: 13.5%; stage II: 35.1%; stage III: 51.4%; Postoperative pain was 4 points at day 0. The surgical site infection rate was 2.7%. Mean hospital stay was 6.3±3.4 days. There was one anastomotic leakage in open conversion group. Mean follow-up period was 41.5 months (12-84 months). There were 7 local recurrences, 4 patients developed liver metastasis and 1 lung metastasis. The overall survival time of all stages was 96.2% (24 months); 92.8% (36 months) and 75.7% (60 months). Conclusion: SPLS for right hemicolectomy is feasible and safe. The cosmetic value is better (short incision confounded by um-bilicus). Other outcomes were equivalent to conventional laparoscopy.
