[Évaluation de la gravité du cancer colorectal dépisté dans le contexte de la crise sanitaire liée au COVID19 en région Ile-de-France]. / Evaluation of the severity of screened colorectal cancer in the context of the health crisis linked to COVID19 in Ile-de-France region.

BACKGROUND: After the announcement in March 2020 of the COVID-19 pandemic, colorectal cancer (CRC) screening programs were suspended in several countries. Compared to the lesions detected during previous campaigns, this study aims to assess the severity of CRC detected during the 2020 screening campaign in Île-de-France, the French region most affected by the 1st wave of the pandemic. METHODS: The descriptive and etiological study included all faecal immunochemical test (FIT) results carried out between January 2017 and December 2020 on people aged 50-74, living in Île-de-France. First, the proportion of colonoscopies performed within one month (One-month-colo) following FIT; the yield of colonoscopy (proportion of colonoscopies with a neoplasm lesion among those performed) and CRC severity (TNM Classification, Level-0: T0/N0/M0, Level-1: T1/T2/N0/M0, Level-2: T3/T4/N0/M0; Level-3: T3/T4/N1/M0; Level-4: M1) were described in 2020 compared to previous campaigns (2017, 2018, and 2019). Subsequently, the link between the level of CRC severity and the predictive factors, including campaign year and time to colonoscopy, was analysed using polytomous multivariate regression. RESULTS: The one-month-colo (2017: 9.1% of 11,529 colonoscopies; 2018: 8.5% of 13,346; 2019: 5.7% of 7,881; 2020: 6.7% of 11,040; p < 0.001), the yield (65.2%, 64.1%, 62.4%, 60.8% respectively, p < 0.001) were significantly different between campaigns. The proportion of CRC level-4 (4.8% in 2017 (653 CRC); 7.6% in 2018 (674 CRC); 4.6% in 2019 (330 CRC) and 4.7% in 2020 (404 CRC); p < 0.29) was not significantly different between campaigns. The probability of having CRC with a high severity level was inversely related to the time to colonoscopy but not to the campaign year. Compared to patients having undergone colonoscopy within 30 days, the odds were significantly reduced by 60% in patients having undergone colonoscopy after 7 months (adjusted Odds-Ratio: 0.4 [0.3; 0.6]; p < 0.0001). CONCLUSIONS: The French indicators were certainly degraded before the first wave of the COVID-19. The delay in access to colonoscopy as well as its extension induced by the COVID-19 crisis had no impact in terms of cancer severity, due to a discriminatory approach prioritizing patients with evident symptoms.

Supply and quality of colonoscopy according to the characteristics of gastroenterologists in the French population-based colorectal-cancer screening program.

BACKGROUND: Since its complete roll-out in 2009, the French colorectal cancer screening program (CRCSP) experienced 3 major constraints [use of a less efficient Guaiac-test (gFOBT), stopping the supply of Fecal-Immunochemical-Test kits (FIT), and suspension of the program due to the coronavirus disease 2019 (COVID-19)] affecting its effectiveness. AIM: To describe the impact of the constraints in terms of changes in the quality of screening-colonoscopy (Quali-Colo). METHODS: This retrospective cohort study included screening-colonoscopies performed by gastroenterologists between Jan-2010 and Dec-2020 in people aged 50-74 living in Ile-de-France (France). The changes in Quali-colo (Proportion of colonoscopies performed beyond 7 mo (Colo_7 mo), Frequency of serious adverse events (SAE) and Colonoscopy detection rate) were described in a cohort of Gastroenterologists who performed at least one colonoscopy over each of the four periods defined according to the chronology of the constraints [gFOBT: Normal progress of the CRCSP using gFOBT (2010-2014); FIT: Normal progress of the CRCSP using FIT (2015-2018); STOP-FIT: Year (2019) during which the CRCSP experienced the cessation of the supply of test kits; COVID: Program suspension due to the COVID-19 health crisis (2020)]. The link between each dependent variable (Colo_7 mo; SAE occurrence, neoplasm detection rate) and the predictive factors was analyzed in a two-level multivariate hierarchical model. RESULTS: The 533 gastroenterologists (cohort) achieved 21509 screening colonoscopies over gFOBT period, 38352 over FIT, 7342 over STOP-FIT and 7995 over COVID period. The frequency of SAE did not change between periods (gFOBT: 0.3%; FIT: 0.3%; STOP-FIT: 0.3%; and COVID: 0.2%; P = 0.10). The risk of Colo_7 mo doubled between FIT [adjusted odds ratio (aOR): 1.2 (1.1; 1.2)] and STOP-FIT [aOR: 2.4 (2.1; 2.6)]; then, decreased by 40% between STOP-FIT and COVID [aOR: 2.0 (1.8; 2.2)]. Regardless of the period, this Colo_7 mo's risk was twice as high for screening colonoscopy performed in a public hospital [aOR: 2.1 (1.3; 3.6)] compared to screening-colonoscopy performed in a private clinic. The neoplasm detection, which increased by 60% between gFOBT and FIT [aOR: 1.6 (1.5; 1.7)], decreased by 40% between FIT and COVID [aOR: 1.1 (1.0; 1.3)]. CONCLUSION: The constraints likely affected the time-to-colonoscopy as well as the colonoscopy detection rate without impacting the SAE's occurrence, highlighting the need for a respectable reference time-to-colonoscopy in CRCSP.

Social Inequalities in Participation in Cervical Cancer Screening in a Metropolitan Area Implementing a Pilot Organised Screening Programme (Paris Region, France).

Objectives: We aimed to examine social inequalities in participation in cervical cancer screening (CCS) in a metropolitan area by implementing a pilot organised screening programme. The pilot programme consisted of sending invitations to women who did not perform a pap smear within the past 3 years, managing interventions to reach vulnerable women, training healthcare professionals, and organising follow-ups of abnormal pap smears. Methods: We studied participation in CCS between January 2014 and December 2016 among 241,257 women aged 25-63 years old. To assess relative inequalities, Odds Ratios were computed using multilevel logistic regression. To assess absolute inequalities, the CCS coverage and the rate difference were calculated. Inequalities were computed by age and neighbourhood characteristics (social deprivation and proportion of single women). Results: Disparities in participation in CCS were observed by age and social deprivation. For overall screening compared to opportunistic screening, disparities by age were larger (OR25-35_vs._55-64 = 2.13 [2.08-2.19] compared to 2.02 [1.96-2.07]), but disparities by social deprivation were decreased (OR10%_most_vs._10%_least_deprived = 2.09 [1.90-2.30] compared to 2.22 [2.02-2.44]). Conclusion: Disparities in CCS participation remain despite the organised programme. To reduce these inequalities, free screening should be proposed and evaluated.

Incidence and consequence of an hepatic artery injury in patients with postcholecystectomy bile duct strictures.

OBJECTIVE: To compare the clinical presentation and results of treatment of postcholecystectomy bile duct injuries in patients with and without arterial injuries. SUMMARY BACKGROUND DATA: Incidence and impact of arterial injuries in patients with a postcholecystectomy biliary injury are unknown, although they are claimed to increase the risk of septic complications, difficulty of biliary repair and risk of recurrent stricture. METHODS: Fifty-five patients referred for postcholecystectomy biliary strictures and who underwent surgical repair were prospectively evaluated by celiac and superior mesenteric angiography. Circumstance and presenting symptoms of the biliary injury in patients with and without vascular injury as well as intra- and postoperative outcome in the 43 patients who underwent a Hepp-Couinaud biliary repair were compared. RESULTS: Incidence of vascular injury was 47%, the most frequent of which was right-sided hepatic artery disruptions (36%). Indication of cholecystectomy (cholecystitis, 42 vs. 45%), technique of resection (laparoscopy, 80 vs. 79%) as well as delay of recognition and presenting symptom of the biliary injury were comparable in patients with and without vascular injury. Among patients undergoing a biliary repair, the level of the biliary injury (Bismuth's type III or IV 63% vs. 54%), duration of surgery, and incidence of postoperative complications (21 vs. 21%) were also comparable in patients with and without arterial injury. One patient in each group experienced recurrent biliary stricture. CONCLUSIONS: The discovery of a disruption of the right branch of the hepatic artery should not affect management of the biliary stricture when if a Hepp-Couinaud repair is performed.
