Concordance and Clinical Significance of Uncommon Variants of Bladder Urothelial Carcinoma in Transurethral Resection and Radical Cystectomy Specimens
2014
To evaluate the concordance and prognostic role of histologic variants of bladder urothelial carcinoma in transurethral resection of bladder tumor (TURBT) and radical cystectomy (RC) specimens. METHODS Clinicopathologic information available at the time of RC and follow-up data from 4110 RC specimens, collected between January 2000 and December 2009 at 17 tertiary referral centers were retrospectively analyzed and evaluated for the presence or absence of uncommon variants of bladder urothelial carcinoma. The presence or absence of uncommon variants of bladder urothelial carcinoma was evaluated on previous TURBT specimens of patients undergoing RC. Cox regression was used to assess the impac…
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…
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…
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.
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:…
Recurrence of Acute Gallstone Pancreatitis and Relationship with Cholecystectomy or Endoscopic Sphincterotomy
2004
To determine the prevalence of recurrence of gallstone pancreatitis, its clinical features, and the presence of prognostic factors of recurrence.From January 1, 2000 to August 31, 2003, 233 patients admitted with acute gallstone pancreatitis (AGP) were prospectively studied. Patients were divided into two groups: recurrent and nonrecurrent group. Clinical, analytical, radiological, prognostic parameters, and severity (Atlanta criteria) were assessed, along with the performance of cholecystectomy or endoscopic sphincterotomy (ES). Clinical features of recurrence were analyzed. Univariate (chi(2), Student's t-test) and multivariate tests were performed. Statistical significance was assumed if…
Endoscopic treatment of the "sump syndrome" after choledochoduodenostomy: a new technique using an amplatzer septal occluder.
2006
A 58-year-old male patient had been suffering for 35 years from recurrent cholangitis, biliary sludge and infection-induced stone formation after open cholecystectomy because of empyema of the gallbladder and severe acute and delayed postoperative complications. The pathophysiological origin of this chronic "sump syndrome" was a choledochoduodenostomy which had been performed prophylactically at the time of the initial operation. The patient agreed to an experimental treatment option with use of an Amplatzer atrial-septal defect (ASD) occluder for closure of the symptomatic choledochoduodenal fistula. The double-disc occluder was introduced through a 9 French diameter and 90 cm long sheath …
Indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.
2008
We determined indications for preoperative prostate biopsy in patients undergoing radical cystoprostatectomy for bladder cancer.Of 316 cystoprostatectomy specimens concomitant prostate cancer was diagnosed in 21.5%. Prostate cancer was diagnosed preoperatively in 24% of cases (evident prostate cancer), 32% were suspicious for prostate cancer but no biopsy was done (suspected prostate cancer) and in 44% prostate cancer was incidental. Patients were stratified into probability groups of intermediate/high risk prostate cancer by digital rectal examination and prostate specific antigen. The incidence of unfavorable histopathology was determined in each group.Of prostate cancers 85% were organ c…
Trocar-related abdominal wall bleeding in 200 patients after laparoscopic cholecistectomy: Personal experience
2006
AIM: To determine the complications and incidence of the first and second access-related vascular injuries induced by videolaparoscopic cholecistectomy. METHODS: We retrospectively reviewed vascular injuries in 200 consecutive patients who underwent videolaparoscopic cholecistectomy from 2003 to 2005. One hundred and one patients with placement of radial expanding trocars were assigned into group A and 99 patients with placement of pyramidal tipped trocars into group B. All the patients were submitted to open access according to Hasson for the first trocar. RESULTS: Bleeding did not occur at the intraoperative cannula-site in group A. However, it occurred at the intraoperative cannula-site …
Urethral fixation technique improves urinary continence recovery in men undergoing open radical cystectomy and ileal orthotopic neobladder
2021
Background We assessed urinary continence recovery and perioperative complications in patients operated on with the novel urethral fixation technique during open radical cystectomy (RC) with ileal orthotopic neobladder (IONB). Methods A retrospective cohort of 82 consecutive male patients undergoing open RC with IONB between 07/2013 and 06/2020 was analyzed. A study group of 48 patients operated on with the urethral fixation technique was compared with a control group of 34 patients receiving standard neovesico-urethral anastomosis. In the study group, the urethral stump was fixed to the dorsal median raphe posteriorly and to the medial portion of levator ani muscle postero-laterally in ord…
