Abstrakt:	Background: Laparoscopic D3 anterior posterior extended mesenterectomy (D3APEM) in right colectomy has received increased attention. The aim of this study is to prove feasibility, systemize technical accomplishment, and provide short-term outcomes data. Methods: From July 2013 to February 2017, 18 patients with adenocarcinoma in the right colon underwent right colectomy with laparoscopic D3APEM, including lymph nodes anterior and posterior to the superior mesenteric vessels. A reconstructed three-dimensional anatomy map derived from the staging computed tomography was used as a road map at surgery. The procedure was systematized into seven operative steps: Step 1, trocar placement and inspection; Step 2, release of the transverse colon; Step 3, identification of the terminal mesenteric vessels; Step 4, release of the anterior flap; Step 5, division of the transverse mesocolon; Step 6, release of the posterior flap; and Step 7, anastomosis and specimen removal. Patient disposition and variations regarding vascular anatomy and ability to expose consequentially may necessitate a variation in the sequence of the steps. Results: A total of 7 (39%) cases were converted, 3 due to bleeding and 4 due to challenging dissection. Median operative time and blood loss were 276 minutes (168-439 minutes) and 200 mL (< 50-1300 mL), respectively. Postoperative complications occurred in 6 (33%), including 2 (11%) major complication requiring reoperation. Median hospital stay was 5 days (3-13 days). R0 resection was achieved in all cases. Median number of the lymph nodes harvested was 40 (25-86), including 11.5 (4-35) in the D3 volume. Six patients (33%) had positive nodes, 3 of them affecting the D3 zone, including 1 case of a skip metastasis. There was no mortality, and at present all the patients are alive. One patient developed distant lymph node metastases. Conclusion: Laparoscopic right colectomy with D3APEM is feasible, associated with acceptable morbidity and fast recovery; now in readiness for introduction in specialized colorectal institutions.
