Prophylactic surgical mesh placement as a prevention of parastomal hernia in open radical cystectomy with ileal conduit diversion - pilot study.

INTRODUCTION: This study examines the efficacy of prophylactic mesh implantation during open radical cystectomy with ileal conduit diversion in preventing parastomal hernias (PH). Despite PH being a common complication, prophylactic methods have been underexplored. METHODS: A pilot, single-center, prospective cohort study was conducted involving five patients undergoing surgery with mesh implantation. Demographic and clinical characteristics were monitored, including the incidence of PH, operation time, blood loss, and hospitalization duration. RESULTS: During the mean follow-up period of 9.1±3.2 months post-operation, no occurrences of PH were observed in the patient group. Despite the risks associated with implanting foreign material in an area of surgery involving open small intestine, no infectious complications were noted. CONCLUSION: Prophylactic mesh implantation in radical cystectomy with ileal conduit diversion appears to be an effective preventive measure against PH. Further extensive studies are required to definitively confirm the efficacy and safety of mesh use in this context.

Echocardiography predictors of sustained sinus rhythm after cardioversion of supraventricular arrhythmia in patients with septic shock.

PURPOSE: The echocardiography parameters may predict the maintenance of sinus rhythm after cardioversion of a supraventricular arrhythmia (SVA). MATERIALS AND METHODS: Patients in septic shock with onset of an SVA, normal to moderately reduced LV systolic function (EF_LV˃̳35%) and on a continuous noradrenaline of <1.0 µg/kg.min were included. Echocardiography was performed at the arrhythmia onset, 1 h and 4 h post cardioversion on an infusion of propafenone or amiodarone. RESULTS: Cardioversion was achieved in 96% of the 209 patients within a median time of 6(1.8-15.6)h, 134(64.1%) patients experienced at least one SVA recurrence after cardioversion. At 4 h the left atrial emptying fraction (LA_EF, cut-off 38.4%, AUC 0.69,p˂0.001), and transmitral A wave velocity-time-integral (Avti, cut-off 6.8 cm, AUC 0.65,p = 0.001) showed as limited predictors of a single arrhythmia recurrence. The LA_EF 44(36,49)%, (p = 0.005) and the Avti 8.65(7.13,9.50)cm, (p < 0.001) were associated with sustained sinus rhythm and decreased proportionally to increasing numbers of arrhythmia recurrences (p < 0.001 and p = 0.007, respectively). The enlarged left atrial end-systolic diameter at the arrhythmia onset (p = 0.04) and elevated systolic pulmonary artery pressure at 4 h (p = 0.007) were weak predictors of multiple(˃3) recurrences. CONCLUSION: The LA_EF and Avti are related to arrhythmia recurrences post-cardioversion suggesting potential guidance to the choice between rhythm and rate control strategies.
