A manipulation angle (MA) of 60\u00b0 has been shown to maximize task efficiency. We calculated the MA used during various stages of both right hemicolectomy (RH) and high anterior resection (AR).<\/jats:p><jats:p><jats:bold>Method\u2002<\/jats:bold> We compared two methods of port placement for each operation. RH\u2010PP1 included ports in the left iliac fossa and left upper quadrant. RH\u2010PP2 included ports suprapubically and in the left iliac fossa. We calculated the MA of each of these methods in mobilizing both the caecum and hepatic flexure. AR\u2010PP1 included ports in the right iliac fossa and right upper quadrant. AR\u2010PP2 included ports suprapubically and in the right iliac fossa. We calculated the MA of each of these methods in mobilizing the splenic flexure, descending\u2013sigmoid junction and the recto\u2013sigmoid junction.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> For RH\u2010PP1, the mean MA for mobilizing the caecum and hepatic flexure was 38\u00b0 and 52\u00b0, respectively. For RH\u2010PP2, the mean MA for mobilising the caecum and hepatic flexure was 58\u00b0 and 44\u00b0, respectively. For AR\u2010PP1, the mean MA for mobilizing the splenic flexure, the descending\u2013sigmoid junction and the recto\u2013sigmoid junction was 77\u00b0, 41\u00b0 and 18\u00b0, respectively. For AR\u2010PP2, the mean MA for mobilizing the splenic flexure, the descending\u2013sigmoid junction and the recto\u2013sigmoid junction was 40\u00b0, 56\u00b0 and 34\u00b0, respectively.<\/jats:p><jats:p><jats:bold>Conclusion\u2002<\/jats:bold> There are no two port placements that will allow for an ideal MA at every stage of mobilization for either right\u2010 or left\u2010sided resection.<\/jats:p>","DOI":"10.1111\/j.1463-1318.2011.02894.x","type":"journal-article","created":{"date-parts":[[2011,11,22]],"date-time":"2011-11-22T13:14:51Z","timestamp":1321967691000},"page":"1132-1137","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Ergonomic port placement in laparoscopic colorectal surgery"],"prefix":"10.1111","volume":"14","author":[{"given":"M.
