Background: It is assumed that robotic-assisted surgery (RAS) may facilitate complex pelvic dissection for rectal cancer compared to the laparoscopic-assisted resection (LAR). The aim of this study was to compare perioperative morbidity, short- and long-term oncologic, and functional outcomes between the RAS and LAR approaches. Methods: Between 2015 and 2021, all rectal cancers operated on by (LAR) or (RAS) were retrospectively reviewed in two colorectal surgery centers. Results: A total of 197 patients were included in the study, with 70% in the LAR group and 30% in the RAS group. The tumor location and stage were identical in both groups (not significant = NS). The overall postoperative mortality rate was not significantly different between the two groups. (0% LAR; 0.5% RAS; NS). The postoperative morbidity was similar between the two groups (60% LAR vs 57% RAS; NS). The number of early surgical re-interventions within the first 30 days was similar (10% for the LAR group and 3% for the RAS group; NS). The rate of complete TME was similar (88% for the LAR group and 94% for the RAS group; NS). However, the rate of circumferential R1 was significantly higher in the LAR group (13%) compared to the RAS group (2%) (p = 0.009). The 3-year recurrence rate did not differ between the two groups (77% for both groups; NS). After a mean follow-up of three years, the incidence of anterior resection syndrome was significantly lower in the LAR group compared to the RAS group (54 vs 76%; p = 0.030). Conclusions: The use of a RAS was found to be reliable for oncologic outcomes and morbidity. However, the expected benefits for functional outcomes were not observed. Therefore, the added value of RAS for rectal cancer needs to be reassessed in light of new laparoscopic technologies and patient management options. [ABSTRACT FROM AUTHOR]

Background: Laparoscopic total gastrectomy with extended lymphadenectomy is a technically demanding surgical procedure with steep learning curve that has limited its widespread use. The aim of this study was to evaluate the feasibility of the robotic approach in total gastrectomy for cancer. We present our experience of 17 consecutive patients who underwent robotic total gastrectomy with intracorporal sutured Roux-en-Y esophagojejunostomy and jejuno jejunostomy between 2014 and 2017. Methods: Data were collected, and patients' demographics and outcomes were examined retrospectively. Results: Seventeen patients with a median age of 68 years (range 32-81) were identified (10 males, 7 females). Mean operative time was 198 minutes (range 108-277) including mean anastomosis time of 25 minutes (range 18-35). There was no conversion to open surgery or requirement for perioperative blood transfusion. Median length of hospital stay was 9 days (range 2-30). Two patients developed postoperative complications including one anastomotic leakage treated conservatively and one internal hernia requiring surgical revision. There was no 90-day mortality or readmission. Conclusion: Robot-assisted total gastrectomy is feasible and reproducible. It overcomes several laparoscopic technical difficulties especially regarding anastomosis. It has the potential to become an alternative to open gastrectomy for gastric cancer. Nevertheless, further follow-up and randomized clinical trials are needed to evaluate mid-term and long-term outcomes of this approach. [ABSTRACT FROM AUTHOR]
