Suture Materials: Do They Affect Fistula and Stricture Rates in Flap Urethroplasties?

2003

<i>Introduction:</i> The effect of suture materials on urethroplasty complications is debated. Indeed, materials with a delayed absorption might either reduce the incidence of fistulas by ensuring a prolonged approximation of neo-urethral edges or increase the risk of urethral strictures due to a prolonged tissue reaction during suture absorption. We retrospectively evaluated the role of suture materials in the complication rate of urethroplasty procedures performed in our institution over a 10-year period. <i>Patients and Methods:</i> Three hundred and thirty-six boys undergoing a flap procedure (parameatal based, preputial tube, or onlay preputial flap) for hypospa…

Intraductal aspiration: a promising new tissue-sampling technique for the diagnosis of suspected malignant biliary strictures

2012

Brushing is the most commonly used technique for biliary sampling at ERCP, despite its limited sensitivity. To evaluate intraductal aspiration (IDA) as a new combined endoscopic technique for cytodiagnosis, its cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. Prospective, observational study. Single tertiary referral center. IDA cellular adequacy, diagnostic accuracy for cancer detection, feasibility, and safety. From April 2009 to September 2010, 42 consecutive patients with suspected malignant biliary stricture underwent ERCP, with tissue sampling obtained with IDA. IDA included performance of standard brushing in all patients. After standard brushing,…

A simple technique of oblique anastomosis can prevent stricture formation in primary repair of esophageal atresia

2012

Abstract Background Anastomotic stricture is an important problem after esophageal atresia (EA) repair. This study evaluates a technique of oblique esophageal anastomosis without use of a flap in order to prevent stricture formation. Methods Medical records of 16 patients (14 with EA type III and 2 with EA type IV Ladd-Gross classification) who underwent primary repair of EA at birth without anastomotic tension were reviewed, evaluating long-term follow-up results. All patients were studied with esophageal contrast study, pH-multichannel intraluminal impedance, and endoscopy. The incidence of complications and their management were analysed. Results Contrast esophagogram and esophagoscopy a…

Long-term outcome of ventral buccal mucosa onlay graft urethroplasty for urethral stricture repair

2004

Abstract Objectives To evaluate our patients who were treated with ventral buccal mucosa onlay grafts for open urethral stricture repair with a follow-up exceeding 5 years. Buccal mucosa onlay is widely used for urethral reconstruction; however, the long-term outcome of these patients remains unclear. Methods During the past 10 years, 67 patients underwent ventral buccal mucosa onlay graft surgery for urethral stricture repair. Of these, 32 were followed up for longer than 5 years (mean 6.9 years) for the occurrence and timing of any postoperative complications. All patients had undergone prior internal urethrotomy (mean 2.9 procedures), and the average length of the stricture was 4.3 cm (r…

Long-Term Results of Internal Urethrotomy

1996

AbstractPurpose: A retrospective analysis was done of long-term results of internal urethrotomy to evaluate risk factors of stricture recurrence.Materials and Methods: Followup studies were performed of 937 patients with urethral strictures treated with internal urethrotomy. Of the patients 357 were treated at Mainz University between 1977 and 1989 (mean followup 4.6 years) and 580 were treated at Bonn University between 1974 and 1986 (mean followup 3.2 years).Results: Strictures recurred in 96 of 357 (26.9 percent) and 260 of 580 (44.8 percent) patients, respectively. Risk factors for recurrence were etiology (post-transurethral resection and inflammation), stricture longer than 1 cm. and …

Treatment with phenoxybenzamine of upper urinary tract complications caused by intravesical obstruction.

1975

Five children in whom reflux and progressive hydronephrosis persisted despite multiple surgical attempts or repair are described. In all cases cystomanometry displayed a marked elevation of the bladder outlet resistance combined with high intravesical pressure values. Therapy with phenoxybenzamine, an alpha-adrenergic blocker, was successful in all cases, restoring a free urine passage of the upper urinary tract and unimpaired voiding preventing urinary diversion which has been considered in some of these children. Although there were no signs of bladder neuropathy, a hyperfunction of the sympathetic innervation as acause for bladder complications is discussed.

Niegodziwi pasterze i Dobry Pasterz Ez 34 w świetle retoryki hebrajskiej

2020

Kontekstem podjętych badań było odmienne opisywanie struktury tekstu Ez 34 przez różnych komentatorów Księgi Ezechiela. Celem badań było odkrycie struktury, którą starożytny autor zaplanował i zapisał. Zastosowano metodę retoryki hebrajskiej, którą opracował Roland Meynet. Osiągnięto następujące wyniki badań: fragment Ez 34,1-10 ma strukturę paralelno-koncentryczną o schemacie: A, B, C, B’, A’. Fragment Ez 34,11-31 też ma strukturę paralelno-koncentryczną o takim samym schemacie. Wniosek, jaki można wyciągnąć z badanego tekstu, sprowadza się do stwierdzenia, że Księga Ezechiela jest aktualna dzisiaj.

Validity of shape memory NiTi colon ring BioDynamix ColonRingTM (or NiTi CAR 27TM) to prevent anastomotic colorectal strictures. Preliminary results

2012

PURPOSE: Anastomotic strictures occur in 3-30% of colorectal anastomosis and one of the main causes may be a reaction to the presence of the metal staples used for suturing. The aim of this study was to evaluate the efficacy of a compression anastomosis ring using the memory shaped device in initial, i.e. nickel-titanium alloy (NiTi) for the prevention of colorectal anastomotic strictures. PATIENTS AND METHODS: A compression anastomosis ring device (NiTi CAR 27) was used to perform compression anastomosis in 20 patients underwent left hemicolectomy and anterior resection of the rectum for carcinoma. An endoscopic check of the anastomosis was carried out at one month and at six months after …

Correlation between fecal calprotectin and inflammation in the surgical specimen of Crohn's disease

2016

Background: An accurate assessment of the inflammatory activity is crucial to establish the most appropriate treatment in Crohn's disease (CD). The present study aimed to evaluate the utility of preoperative fecal calprotectin (FC) measurement in small bowel CD and its relationship with inflammatory activity in surgical pathology specimens. Methods: This was a prospective observational study including all the patients with small bowel CD operated on at our center between March 2011 and September 2013. Preoperative laboratory and stool tests were performed. A meticulous exploration of entire small bowel was performed during surgery, and the resected bowel (or a sample of whole intestinal wal…
