RESUMO

BACKGROUND: Bile duct injury (BDI) is accompanied by significant morbidity and long-term impact in quality of life. Subtotal cholecystectomy (STC) is an alternative to prevent this outcome but is associated with other complications. The aim of this work is to demonstrate that BDI associated morbidity exceeds STC associated morbidity, underscoring STC as a reasonable bail out strategy. METHODS: We compared 115 patients who underwent STC with 293 patients who were referred to our center with BDI type E1-E3 and underwent surgical repair. The groups were comparable because in both instances the surgeon had the opportunity to decide not to perform a total cholecystectomy once critical view of safety (CVS) was not achieved. RESULTS: Bile leakage was found in 21% of the STC group with only one BDI (0.9%). More Accordion ≥ 4 were found in the STC group (10.4% vs 4.8%, p = 0.035); however, reoperations were more frequent in the BDI group (8.2% vs 0.9%, p = 0.006). No patient in the STC group required reintervention for completion cholecystectomy. After 3.8 years follow-up, 2.4% of patients had secondary biliary cirrhosis in the BDI group; none in the STC group. CONCLUSIONS: Despite complications of STC, morbidity associated with BDI is much higher due to high long-term reoperation rate, in addition to secondary biliary cirrhosis. STC is a safe alternative that can prevent BDI if properly and timely performed in the context of difficult cholecystectomy.

RESUMO

Marine ecosystems are both stressed and threatened by pesticides that are used on land. Nevertheless, research on the impact of pesticides on coral reefs and the underlying mechanisms is still in its infancy. The insecticide chlordecone is a persistent organic pollutant with carcinogenic effects in rats and mice. Chlordecone has been detected in diverse marine organisms in the Caribbean, but unexpectedly, also in French Polynesia. We combined transcriptomic and morphologic analyses of analyses the response of the coral Pocillopora damicornis to chlordecone stress. We compared chlordecone stress with thermal stress to determine a chlordecone-specific response. We found eight transcripts related to the P450-1A or P450-3A families that were specifically overexpressed in response to chlordecone. There was also sequential overexpression of transcripts involved in apoptosis and degradation of cellular matrix proteins. Finally, we report the first observation of chlordecone-induced P. damicornis polyp bail-out. Altogether, these results strongly suggest that apoptosis and expression of genes belonging to the cathepsin family are sequentially regulated processes leading to coenosarc dissociation and loss.
