RESUMO
BACKGROUND: Substantial variation exists when performing a minimally invasive right hemicolectomy (MIRH) due to disparities in training, expertise and differences in implementation of innovations. This study aimed to achieve national consensus on an optimal and standardized MIRH technique for colon cancer and to develop and validate a video-based competency assessment tool (CAT) for MIRH. METHOD: Statements covering all elements of MIRH were formulated. Subsequently, the Delphi technique was used to reach consensus on a standardized MIRH among 76 colorectal surgeons from 43 different centres. A CAT was developed based on the Delphi results. Nine surgeons assessed the same 12 unedited full-length videos using the CAT, allowing evaluation of the intraclass correlation coefficient (ICC). RESULTS: After three Delphi rounds, consensus (≥80% agreement) was achieved on 23 of the 24 statements. Consensus statements included the use of low intra-abdominal pressure, detailed anatomical outline how to perform complete mesocolic excision with central vascular ligation, the creation of an intracorporeal anastomosis, and specimen extraction through a Pfannenstiel incision using a wound protector. The CAT included seven consecutive steps to measure competency of the MIRH and showed high consistency among surgeons with an overall ICC of 0.923. CONCLUSION: Nationwide consensus on a standardized and optimized technique of MIRH was reached. The CAT developed showed excellent interrater reliability. These achievements are crucial steps to an ongoing nationwide quality improvement project (the Right study).

BACKGROUND: Pilonidal sinus disease impacts patient's quality of life. In the Netherlands, it is often treated with excision and secondary healing, which is associated with high recurrence rates and poor wound healing. The Bascom cleft lift, an alternative technique, has shown favorable healing times and recurrence rates. OBJECTIVE: The present study aims to compare successful wound healing, time to healing, complications, and recurrence rate between excision with secondary wound healing and Bascom cleft lift. DESIGN: This is a multicenter retrospective study. SETTINGS: Three institutions in the Rotterdam region of the Netherlands participated in the study. PATIENTS: Patients who underwent excision with secondary healing or Bascom Cleft Lift between July 2015 and August 2021 were included. MAIN OUTCOME MEASURES: Primary endpoints included the rate of successful wound healing and the time to achieve healing. Secondary endpoints included postoperative complications and recurrence rate within twelve months after surgery. RESULTS: Out of 272 patients, 128 underwent Bascom cleft lift and 144 patients excision and secondary healing. Recurrent PSD (47.7% vs 22.2%) and abscess history (53.1% vs 40.3%) were more common in the Bascom cleft lift group compared to excision with secondary wound healing. The median follow-up period at the outpatient clinic was 43 days. Wound healing was 84.4% after Bascom cleft lift vs. 32.6% after excision and secondary healing (p < 0.001), with median time to wound healing of 55 days and 101 days, respectively (p < 0.001). Complications were 28.9% for Bascom cleft lift vs. 13.2% for excision and secondary healing (p = 0.003). Recurrent disease was 6.3% after Bascom Cleft Lift and 11.8% after excision and secondary healing (p = 0.113). LIMITATIONS: It has a retrospective design which makes it prone to selection bias and residual confounding. Additionally, the study's short follow-up period further adds to these limitations as longer follow-up may better identify true recurrence rates. Finally, a deficiency is the absence of collected patient satisfaction data, which is nowadays a common scientific issue. CONCLUSIONS: This retrospective study shows that Bascom cleft lift is superior to excision and secondary healing given the higher percentage of patients with successful wound healing within a shorter time.

RESUMO
Objective: The aim of this study was to systematically review the literature for each surgical step of the minimally invasive right hemicolectomy (MIRH) for non-locally advanced colon cancer, to define the most optimal procedure with the highest level of evidence. Background: High variability exists in the way MIRH is performed between surgeons and hospitals, which could affect patients' postoperative and oncological outcomes. Methods: A systematic search using PubMed was performed to first identify systematic reviews and meta-analyses, and if there were none then landmark papers and consensus statements were systematically searched for each key step of MIRH. Systematic reviews were assessed using the AMSTAR-2 tool, and selection was based on highest quality followed by year of publication. Results: Low (less than 12 mmHg) intra-abdominal pressure (IAP) gives higher mean quality of recovery compared to standard IAP. Complete mesocolic excision (CME) is associated with lowest recurrence and highest 5-year overall survival rates, without worsening short-term outcomes. Routine D3 versus D2 lymphadenectomy showed higher LN yield, but more vascular injuries, and no difference in overall and disease-free survival. Intracorporeal anastomosis is associated with better intra- and postoperative outcomes. The Pfannenstiel incision gives the lowest chance of incisional hernias compared to all other extraction sites. Conclusion: According to the best available evidence, the most optimal MIRH for colon cancer without clinically involved D3 nodes entails at least low IAP, CME with D2 lymphadenectomy, an intracorporeal anastomosis and specimen extraction through a Pfannenstiel incision.
