Postoperative complications and 90-day mortality in radical cystectomy in high-risk patients: A monocentric retrospective observational study.
2018
Aim: Assessing the incidence of immediate postoperative complications and 90-day mortality in high-risk patients who have undergone radical cystectomy; evaluating the correlation between preoperative conditions and surgery outcomes. Materials and methods: This is a monocentric retrospective observational study in which data of 65 patients have been analyzed. High-risk criteria: (a) Age ≥75 years, (b) obesity, (c) age-adjusted Charlson Comorbidity Index ≥8, (d) anemic status, and (e) pT ≥3. More than 50% of patients had two or more “high-risk” indicators. Postoperative complications were assessed through Clavien–Dindo classification. Results: Average age of patients was 70.4 years, average a…
Selective pelvic autonomic nerve stimulation with simultaneous intraoperative monitoring of internal anal sphincter and bladder innervation.
2010
<i>Background:</i> Pelvic autonomic nerve preservation avoids postoperative functional disturbances. The aim of this feasibility study was to develop a neuromonitoring system with simultaneous intraoperative verification of internal anal sphincter (IAS) activity and intravesical pressure. <i>Methods:</i> 14 pigs underwent low anterior rectal resection. During intermittent bipolar electric stimulation of the inferior hypogastric plexus (IHP) and the pelvic splanchnic nerves (PSN), electromyographic signals of the IAS and manometry of the urinary bladder were observed simultaneously. <i>Results:</i> Stimulation of IHP and PSN as well as simultaneous intraop…
Intraoperative Monitoring of Bladder and Internal Anal Sphincter Innervation: A Predictor of Erectile Function following Low Anterior Rectal Resectio…
2013
<b><i>Background:</i></b> The objective was to investigate whether two-dimensional intraoperative neuromonitoring (IONM) of pelvic autonomic nerves has the potential to predict erectile function (EF) following surgery for rectal cancer. <b><i>Methods:</i></b> A consecutive series of 17 sexually active male rectal cancer patients undergoing IONM-based nerve-sparing low anterior rectal resection were evaluated prospectively. IONM was performed by electric stimulation of the pelvic splanchnic nerves with concomitant electromyography of the internal anal sphincter and cystomanometry. Sexual function was assessed using a validated questionnaire. &l…
Effects of Ca2+ channel antagonists in guinea-pig normal and skinned gall bladder.
1993
CaCl2 (0.01-50 mM, in K(+)-depolarized tissues), KCl (0.1-100 mM) and acetylcholine (1 nM-10 mM) produced concentration-dependent contractions of guinea-pig isolated gall bladder. Nifedipine (1-100 microM), verapamil (1-100 microM), diltiazem (1-100 microM), cinnarizine (1-100 microM), and flunarizine (1-100 microM) each produced a concentration-related inhibition of the log concentration-effect curve for CaCl2. The rank order of potencies of these antagonists, measured as the IC50 against Ca2+ (50 mM)-induced contraction of depolarized gall bladder, was diltiazem (0.25 microM)or = verapamil (0.8 microM) approximately nifedipine (1.2 microM)cinnarizine (25 microM) approximately flunarizine …
Type 2 diabetes mellitus predicts worse outcomes in patients with high-grade T1 bladder cancer receiving bacillus Calmette-Guérin after transurethral…
2020
Objectives: The aim of this multicenter study was to investigate the prognostic role of type 2 diabetes mellitus (T2DM) comorbidity in a large multi-institutional cohort of patients with primary T1HG/G3 non–muscle-invasive bladder cancer (NMIBC) treated with transurethral resection of the bladder (TURB). Materials and methods: A total of 1,172 patients with primary T1 HG/G3 who had NMIBC on re-TURB and who received adjuvant intravesical bacillus Calmette-Guérin therapy with maintenance were included. Endpoints were recurrence-free survival and progression-free survival. Results: A total of 231 (19.7%) of patients had T2DM prior to TURB. Five-year recurrence-free survival estimates were 12.5…
Assisted reproductive techniques and risk of exstrophy-epispadias complex: a German case-control study.
2012
We assessed the risk of exstrophy-epispadias complex in children conceived by in vitro fertilization or intracytoplasmic sperm injection.Data from the German Network for Congenital Uro-REctal malformations were compared to nationwide data from the German In Vitro Fertilization Register and the German Federal Statistical Office. Odds ratios (95% CI) were determined to quantify associations using logistic regression.A total of 123 patients with exstrophy-epispadias complex born in Germany between 1997 and 2011 were recruited through participating departments of pediatric urology and pediatric surgery throughout the country as well as the German self-help organizations Blasenekstrophie/Epispad…
Sigma-rectum pouch (Mainz pouch II).
1993
A substantial modification of the classic technique of ureterosigmoidostomy is introduced in this article. To date, this procedure has been used in 47 patients. This article reviews the surgical technique of the antemesenterial splitting of the intestine at the recto-sigmoid junction which creates a pouch by subsequent side-to-side anastomosis.
Modified FOLFIRINOX versus CisGem first-line chemotherapy for locally advanced non resectable or metastatic biliary tract cancer (AMEBICA)-PRODIGE 38…
2019
IF 3.287 (2017); International audience; IntroductionCombination of cisplatine and Gemcitabine (CisGem) is the reference 1st line Chemotherapy in patients with advanced biliary cancer. FOLFIRINOX demonstrated an overall survival superiority when compared to gemcitabine in 1st line for patients with metastatic pancreatic adenocarcinoma. Because of similarities between pancreatic and biliary cancers, we proposed a randomized trial comparing mFOLFIRINOX and CisGEm.AimPRODIGE38-AMEBICA is a phase II/III trial evaluating efficacy of modifed FOLFIRINOX (D1 bolus removed) or CisGEm on patients with locally advanced non resectable or metastatic biliary tract cancer.Patients and methodsMain inclusio…
Effect on postoperative survival of the status of distal ureteral margin: The necessity to achieve negative margins at the time of radical cystectomy.
2015
Background: Despite several studies, the adequate management of positive distal ureter margins at the time of radical cystectomy (RC) remains controversial. Particularly, it is not clear whether the achievement of negative distal ureter margins at the intraoperative frozen sections (IFS) affects postoperative cancer-specific mortality (CSM). Methods: In all, 1,447 consecutive patients treated with RC at a single center between January 1987 and August 2014 were considered. Multivariable (MVA) logistic regression analyses were used to determine predictors of positive IFS. MVA Cox regression analyses were used to test the effect on CSM of intraoperative conversion to negative margins. Results:…
Enteroscopic Cyanoacrylate Sclerotherapy of Jejunal and Gallbladder Varices in a Patient with Portal Hypertension
2001
Bleeding from varices outside the gastroesophageal region is a rare, but regularly reported complication of portal hypertension. The treatment differs from the management of esophageal and gastric varices. We present here a report on the diagnosis and treatment of bleeding jejunal and gallbladder varices in a man with portal hypertension caused by chronic calcifying pancreatitis. The patient was suffering from recurrent, frequent, and massive gastrointestinal bleeding from varices at the anastomotic area of a cholecystojejunostomy. For diagnostic purposes, we carried out percutaneous Duplex ultrasonography and push enteroscopy with the Doppler technique. The treatment of varices in this are…
