INTRODUCTION: The concept of complete mesocolic excision (CME) with central vascular ligation (CVL) for treatment of right @entity694 evolved over last one decade. It decreases local recurrences and improves the survival rates. We describe our novel technique which involves first posterior sharp dissection between planes of @entity10478 of mesocolon followed by ligation of ileocolic, right colic and middle colic pedicles at their origin. We highlight the technical variations with various techniques and advantages over conventional medial to lateral approach in current study. AIM: The outcomes were measured in terms of technical feasibility, short-term outcomes and pathological radicality of current laparoscopic technique (IRETA) for CME with CVL. MATERIALS AND METHODS: Two hundred twelve @entity1 (163 males) who underwent laparoscopic CME for right @entity694 over the period of January 2009 to December 2013 were analysed via prospectively maintained database. RESULTS: 97.16  % of @entity1 (n   =   206) underwent laparoscopic CME while six @entity1 required open conversion. Mean operative time was 142        28.4  min with median hospital stay of 5  days (range 4-11). The median count of lymph node harvested were 24 (range 10-42). The complete mesocolic excision plane was achieved in 93.8  % @entity1 . 84.4  % (n   =   179) of our @entity1 were having (T3, N+) disease on pathological examination. The overall morbidity (<30  days) was 9.9  %. CONCLUSION: Laparoscopic initial retrocolic endoscopic tunnel approach (IRETA) for CME with CVL in right @entity694 is safe, simpler and feasible laparoscopic approach with minimal complications. Creation of retro colic tunnel is key highlight of IRETA approach. This approach becomes especially useful in @entity1 with late presentations where complete mesocolic excision remains essential to enhance oncological radicality as per evidence available.
