RESUMO

PURPOSE: The concept of complete mesocolic excision (CME) in right-sided colorectal cancer is well known for open and laparoscopic surgery. The aim of this study was to evaluate and compare perioperative and oncological outcomes of reduced port and open surgery for right-sided colorectal cancer. METHODS: One hundred forty-one patients received elective surgery for right-sided colonic cancer between January 2015 and December 2019 and were included in a retrospective database. RESULTS: We observed longer operation time in the RP-CME group (145 min vs. 119.43 min, p<0.01). Hospital stay (8 days vs. 14 days, p<0.01) and time to first intestinal passage (42 h. vs. 59 h, p<0.01) were significantly shorter in the reduced port group. Postoperative complications were more likely to be observed in the O-CME group (7.2% vs. 14.1%, p=0.28); anastomotic leakage rate was low in both groups (1.8% vs. 2.4%, p=1.00). Specimen scores (score 1= good: 93.8% vs. 91.7%, p=1.00) and average number of retrieved lymph nodes were comparable (24 vs. 23 p=0.69). In O-CME patients, we observed more advanced tumor stages (UICC III: 21.4% vs. 45.9%, p<0.01). CONCLUSION: To our knowledge, this is the first study comparing reduced port to open surgery for right-sided colorectal cancer. We could demonstrate that this technique is feasible for oncological right hemicolectomy with observation of shorter hospital stay and lower morbidity rates compared to open surgery. The oncological outcome did not differ in the present study.

RESUMO

OBJECTIVE: The aim of this study was to develop an objective and reliable surgical quality assurance system (SQA) for COLOR III, an international multicenter randomized controlled trial (RCT) comparing transanal total mesorectal excision (TaTME) with laparoscopic approach for rectal cancer. BACKGROUND OF SUMMARY DATA: SQA influences outcome measures in RCTs such as lymph nodes harvest, in-hospital mortality, and locoregional cancer recurrence. However, levels of SQA are variable. METHOD: Hierarchical task analysis of TaTME was performed. A 4-round Delphi methodology was applied for standardization of TaTME steps. Semistructured interviews were conducted in round 1 to identify key steps and tasks, which were rated as mandatory, optional, or prohibited in rounds 2 to 4 using questionnaires. Competency assessment tool (CAT) was developed and its content validity was examined by expert surgeons. Twenty unedited videos were assessed to test reliability using generalizability theory. RESULTS: Eighty-three of 101 surgical tasks identified reached 70% agreement (26 mandatory, 56 optional, and 1 prohibited). An operative guide of standardized TaTME was created. CAT is matrix of 9 steps and 4 performance qualities: exposure, execution, adverse event, and end-product. The overall G-coefficient was 0.883. Inter-rater and interitem reliability were 0.883 and 0.986. To enter COLOR III, 2 unedited TaTME and 1 laparoscopic TME videos were submitted and assessed by 2 independent assessors using CAT. CONCLUSION: We described an iterative approach to develop an objective SQA within multicenter RCT. This approach provided standardization, the development of reliable and valid CAT, and the criteria for trial entry and monitoring surgical performance during the trial.
