Totally robotic right hemicolectomy: a multicentre case-matched technical and peri-operative comparison of port placements and da Vinci models

The objective of the study was to review the technical and peri-operative outcomes using the da Vinci Xi (dVXi) and da Vinci Si (dVSi) models with suprapubic port placement (SPPP) or traditional port placements (TPP) during a robotic right hemicolectomy (RRHC). A retrospective review was undertaken of prospectively maintained databases of RRHC performed by two senior colorectal surgeons in the USA and Australia. Data were prospectively collected for patient demographics, intra-operative technical outcomes and peri-operative clinical outcomes. A cohort of 138 patients underwent RRHC between 2013 and 2017: 134 (97%) had intra-corporeal anastomoses (ICA), 50% for polyp disease and 38% for cancer. 16 (12%) patients had post-operative complications, 11 (8%) of whom had only one complication. There were five (4%) anaemias requiring transfusion; five (4%) anastomotic bleeds; one (1%) leucocytosis/sepsis; two (1%) paralytic ileus; and two (1%) delayed readmissions. There were no conversions to open operations, anastomotic leaks, 30-day readmissions, or 30-day mortalities. With dVSi compared to dVXi, median (IQR) total operation time (TOT) reduced by 16% [134 (118–169) min versus 113 (90–132), p
