Background: Intracorporeal anastomosis (IA) in right colectomies shows many advantages over extracorporeal anastomosis (EA). Many difficulties encountered in laparoscopic IA can be overcome with hybrid robot-assisted IA or recently with totally robotic procedures. In the literature, few works have been published comparing laparoscopic, hybrid, and totally robotic right colectomies. The aim of this study is to retrospectively analyze the improvements brought on by the evolution of robotic surgery at our specialized center., Materials and Methods: Two hundred six (hybrid and totally) robotic right colectomies (RRCs) with IA were compared with 160 laparoscopic right colectomies (LRCs) with EA. A separate analysis carried out by the robotic group compared 30 totally robotic right colectomies (TRRCs) with 176 hybrid robot-assisted right colectomies (HRRCs). Demographics, pathological features, operative details, and postoperative outcomes were retrospectively analyzed from a prospectively maintained database., Results: The groups were comparable with respect to demographics and tumor staging. When compared with LRC, RRC showed shorter time to first flatus (P < .001), stools (P < .001), solid diet (P < .001), and discharge (P < .001). The number of lymph nodes harvested was 23.13 ± 11.2 in RRC versus 20.5 ± 11.2 in LRC (P = .031). Operative time was longer in RRC (253.0 ± 47 minutes versus 209.9 ± 64 minutes; P < .001), but conversion to open (2.4% versus 18.1%; P < .001), anastomotic leaks (0.5% versus 5%; P = .012), and bleeding (0.3% versus 4.4%; P = .024) were significantly less frequent. Subsequent analysis shows no significant increase in operative time in TRRC versus HRRC (261.0 ± 41 minutes versus 251.6 ± 47.6 minutes; P = .310). Even if not statistically significant, TRRC showed faster bowel function recovery and tolerance to solid diet., Conclusions: We confirmed the clinical advantages of RRC with IA over LRC with EA in postoperative recovery outcomes and complication rate. Furthermore, our preliminary analysis in a cohort of 30 TRRC shows promising results.

Introduction: Extracorporeal ileocolic anastomosis in laparoscopic right hemicolectomy for cancer has a significant risk of complications. The aim of this study is to evaluate the operative and postoperative results of hybrid right hemicolectomy with intracorporeal robotic-assisted anastomosis for adenocarcinoma of the ascending colon compared with the standard extracorporeal anastomosis in a case control study., Patients and Methods: Forty-eight right hemicolectomies for cancer (2009-2012) with laparoscopic medial to lateral dissection, vascular ligation, bowel transection, and robotic-assisted intracorporeal anastomosis with specimen extraction through a Pfannestiel incision (robotic group [RG]) were compared with 48 laparoscopic hemicolectomies (2009-2011) with extracorporeal anastomosis (laparoscopic group [LG])., Results: The two groups were comparable with respect to age, gender, stage of cancer, and body mass index. Surgery time was significantly longer in RG patients (RG, 266±41 minutes; LG, 223±51 minutes; P<.05). Operative results were similar in the two groups. Recovery of bowel function (day of first bowel movement: RG, 3.0±1.0 days; LG, 4.0±1.2 days; P<.05) and hospital stay (RG, 7.5±2.0 days; LG, 9.0±3.2 days; P<.05) were quicker and shorter, respectively, in RG. There were four anastomotic complications and four incisional hernias in LG and none in RG (P<.05)., Conclusions: There are fewer anastomotic and wound complications in RG patients. Intracorporeal robotic-assisted ileocolic anastomosis allows a faster recovery compared with extracorporeal anastomosis.
