Long-term outcome after implementation of endovascular-first strategy to treat acute mesenteric ischemia.

OBJECTIVE: To evaluate the rationale of an aggressive endovascular-first strategy to treat elderly patients with acute mesenteric ischemia (AMI) by studying long-term survival, readmissions, and patients' discharge to home vs nursing facility a decade after an episode of AMI. METHODS: The retrospective study cohort included 66 consecutive patients (all-comers) treated for arterial occlusive AMI between 2009 and 2013. Endovascular revascularization (EVR) was attempted in 50 patients (EVR+), whereas 16 patients were treated without attempted revascularization (EVR-). All patients were followed until death or September 2022. Studied outcomes included discharge status, long-term survival and cause of death and readmissions related to AMI. RESULTS: The mean age of all 66 patients was 78 ± 10 years: 79 ± 9 years in the EVR+ group and 76 ± 12 years in the EVR- group. EVR was technically successful in 44 patients (88%); three patients underwent subsequent open revascularization after EVR failure. One-third required bowel resection after EVR. The 30-day mortality for all patients was 44%; 32% in the EVR+ group and 81% in the EVR- group. Only two survivors were permanently institutionalized, whereas all others were discharged to the same place they lived prior to the AMI episode. There were four AMI-related readmissions during the follow-up; all were in the EVR+ group. Two patients underwent reinterventions for recurrent AMI. One-year survival was 52% for EVR+ and 19% for EVR- patients. Five-year survival rates were 18% and 13%, respectively. The causes of deaths were mesenteric ischemia in 22, other cardiovascular event in 21, and non-cardiovascular cause in 19 patients. Four patients were alive at the end of the follow-up. CONCLUSIONS: In this unselected elderly population with AMI, the aggressive strategy to attempt EVR resulted in a high revascularization rate and favorable outcomes. The high proportion of patients returning to their prior living status and low readmission rate after survival from AMI encourages active treatment of high-functioning elderly patients.

Appendiceal perforation due to biliary stent migration in a neutropenic patient with lung cancer receiving chemotherapy: A case report.

The use of biliary stents has become a common and usually safe procedure. However, the migration of biliary stents is an uncommon but well-recognized event after endoscopic retrograde cholangiopancreatography. The migration of plastic stents usually does not result in complications and are spontaneously eliminated from the gastro-intestinal tract. Additionally, <1% of migrated stents result in intestinal perforation, which typically occurs at the duodenum. Chemotherapeutic agents may cause gastrointestinal toxicity and hematologic toxicity predisposing to neutropenic enterocolitis. The current study reports a patient with an unprecedented case of biliary stent migration resulting in appendiceal gangrene and perforation in a neutropenic patient under chemotherapy for metastatic small cell lung cancer.
