Normothermic Regional Perfusion and Hypothermic Oxygenated Machine Perfusion for Livers Donated After Controlled Circulatory Death With Prolonged Warm Ischemia Time: A Matched Comparison With Livers From Brain-Dead Donors.

Prolonged warm ischemia time (WIT) has a negative prognostic value in liver transplantation (LT) using grafts procured after circulatory death (DCD). To assess the value of abdominal normothermic regional perfusion (A-NRP) associated with dual hypothermic oxygenated machine perfusion (D-HOPE) in controlled DCD LT, prospectively collected data on LTs performed between January 2016 and July 2021 were analyzed. Outcome of controlled DCD LTs performed using A-NRP + D-HOPE (n = 20) were compared to those performed with grafts procured after brain death (DBD) (n = 40), selected using propensity-score matching. DCD utilization rate was 59.5%. In the DCD group, median functional WIT, A-NRP and D-HOPE time was 43, 246, and 205 min, respectively. Early outcomes of DCD grafts recipients were comparable to those of matched DBD LTs. In DCD and DBD group, incidence of anastomotic biliary complications and ischemic cholangiopathy was 15% versus 22% (p = 0.73) and 5% versus 2% (p = 1), respectively. One-year patient and graft survival was 100% versus 95% (p = 0.18) and 90% versus 95% (p = 0.82). In conclusion, the association of A-NRP + D-HOPE in DCD LT with prolonged WIT allows achieving comparable outcomes to DBD LT.

Emergency surgery for bowel obstruction in extremely aged patients.

BACKGROUND: As a result of the increasing of life expectancy, the incidence of pathologies that can lead to operation for bowel obstruction is also increasing. Comorbidities and reduced physiological reserve can decrease elderly patients' ability to tolerate operations especially in an emergency context. We retrospectively evaluated the treatment and outcomes of a cohort of patients aged more than 85 years who underwent emergency surgery for intestinal occlusion. METHODS: Two hundred seventy-eight patients who were admitted to our Institution and operated for acute bowel obstruction have been included in our study. We divided the study population in 2 groups (group A: patients aged>85 years old; group B patients aged ≤85 years). We evaluated the differences between the two groups in terms of intestinal occlusion aetiology, surgical procedures, morbidity and mortality rates. RESULTS: Group A consisted of 57 patients, group B of 221; elderly patients trend in ASA score classification was significantly towards high risk for elderly group; statistical analysis did not show differences in terms of bowel obstruction etiology (except colon volvulus, more frequent in advanced age), type of procedure, duration of hospital stay, procedure-related complication rate. Perioperative mortality was significantly higher in elderly group, due to the mayor incidence of cardiovascular and respiratory fatal events directly related to pre-existing comorbidities. CONCLUSIONS: Despite the high surgical risk, early diagnosis and treatment of the obstructive disease can lead to achieve encouraging outcomes also in extremely advanced age; an aggressive evaluation of comorbidities and the cardiorespiratory risks reduction, when possible, could be useful in improve postoperative outcomes in terms of mortality.

Early surgical management of acute cholecystitis in ultra-octogenarian patients: our 5-year experience.

BACKGROUND: Acute calculous cholecystitis is a leading cause for hospital admission especially in developed countries. As older age population increases, medical research should consider the efficacy of all therapeutic options, including early surgical procedure in an emergency context, for the treatment of acute cholecystitis in elderly high-risk patients. METHODS: From 01/01/2012 to 31/12/2016, 245 patients were admitted to our Institution with diagnosis of acute cholecystitis and managed with cholecystectomy within the same hospitalization. The study population was divided into 2 subgroups: group A (patients aged more than 80 years) and group B (patients within the limit of 80 years of age); the objective of the study was to evaluate and compare the surgical outcomes of the 2 groups in terms of conversion rate, mortality rate, overall morbidity and procedure-related complication rates. RESULTS: Statistical analysis did not show significant differences between ultra octogenarian and younger patients in terms of conversion to open procedure, iatrogenic bile duct lesions, postoperative peritoneal bleeding, bile leakage and peritoneal collection; no differences in terms of hospital stay have been demonstrated. Mortality and overall morbidity rates, even if similar to what observed in Literature and within acceptable values, were significantly higher in elderly patients, due to the presence of severe comorbidities leading to potentially fatal postoperative events. CONCLUSIONS: Minimally invasive approach in an emergency setting for acute cholecystitis seems to be a feasible and adequate therapeutic approach for extremely aged high-risk patients.
