Sonographic biometry in obstructive uropathy of children: preoperative diagnosis and postoperative monitoring.

1985

Renal sonography was performed in 92 children with obstructive uropathy or vesicoureteral reflux preoperatively and at follow-up. Renal volume and the anteroposterior diameter of the renal pelvis proved to be the most reliable morphometric criteria for objective sonographic staging and follow-up of urinary tract obstruction. If transient obstruction occurred after uncomplicated antireflux ureterovesico-plasties (n = 41), it lasted at most 4 weeks. Kidneys with transient postoperative ureterovesical junction obstruction (n = 21) reverted to normal sonographic pattern within 4 weeks following ureteral reimplantation. In cases of ureteropelvic junction obstruction (n = 30), it took up to 6 mon…

Lethal Anaphylactic Reaction to Intravenous Gelatin in the Course of Surgery

2016

Plasma volume expanders (PVEs) are widely used to increase circulating blood volume. Gelatins used as PVEs are heterogeneous mixtures of polypeptides, usually prepared by hydrolysis of bovine collagen containing large amounts of proline and hydroxyproline residues. It has been shown that gelatins can cause anaphylactic reactions. We describe the case of a 73-year-old man who during surgery for intestinal obstruction presented a lethal anaphylactic reaction after the administration of a PVE containing gelatin lysate. The reaction occurred 10 minutes after the start of plasma expander infusion. Then, patient became comatose, and he died without awakening after 76 days. Necroptic aspects and h…

Effect of chronic bladder outlet obstruction on blood flow of the rabbit bladder.

2001

Previous studies have shown that the initial reaction of the rabbit bladder to partial bladder outlet obstruction is increased blood flow at day 1 and a return to baseline blood flow at 1 week. Mucosal and muscle blood flow followed this pattern but mucosal blood flow was always 4 to 5-fold greater. In this study we examined the effect of 4 weeks of outlet obstruction on bladder blood flow and correlated it with the severity of bladder contractile dysfunction.A total of 14 male New Zealand White rabbits underwent partial outlet obstruction creation by standard methods. After 4 weeks the rabbits were anesthetized, and blood flow to the muscle and mucosa was determined by standard fluorescent…

Trends in Frequency and Management of Obstructing Colorectal Cancers in a Well-Defined Population

2007

Few population-based studies investigate obstructing colorectal cancers. This study was designed to describe trends in their frequency and management. Data were obtained for 13,331 colorectal cancers registered by the population-based cancer registry of Burgundy, France, between the years 1976 and 2000. Obstructing cancers represented 8.3 percent of all colorectal cancers. This proportion was stable throughout the study. Resection for cure increased from 54.9 percent (1976–1980) to 71.4 percent (1996–2000; P = 0.011). Using multivariate analysis, site of cancer and period of diagnosis were the only factors significantly associated to a curative resection. Postoperative mortality for obstruc…

Giant hepatic hydatid cyst as a cause of small bowel obstruction.

2006

Today, giant hydatid cysts are fairly rare even in endemic areas. We describe a case of an extremely large hydatid cyst of the liver that was causing massive compression of the neighboring organs, giving rise to a subocclusive syndrome of the intestine. After considering the various approaches available for the treatment of this disease, it was decided that radical surgery was still the best therapeutic choice, especially when extremely large cysts are involved. In particular, in clinical situations where it is difficult to perform radical surgical procedures, less aggressive surgery followed by drug treatment should be the treatment of choice.

Management of nasal septal abscess in childhood: our experience.

2004

Summary A nasal septal abscess is usually the result of an infected hematoma of the septum. A secondary septal abscess may be the result of infections extending from any of the neighbouring tissues. The necrosis of septal cartilage may lead to nasal deformities and severe impairment of nasal patency and growth. Objectives: Assess if the drainage of the abscess and the immediate reconstruction of the destroyed nasal septum in the acute phase is the best treatment to prevent short- and long-term effect on nasal and midface growth. Methods: Three pediatric patients treated with drainage and immediate implantation of homologous bank cartilage prior to 1990 and four treated with mosaic plastic u…

Secondary aortoduodenal fistula.

2008

Aorto-duodenal fistulae (ADF) are the most frequent aorto-enteric fistulae (80%), presenting with upper gastrointestinal bleeding. We report the first case of a man with a secondary aorto-duodenal fistula presenting with a history of persistent occlusive syndrome. A 59-year old man who underwent an aortic-bi-femoral bypass 5 years ago, presented with dyspepsia and biliary vomiting. Computed tomography scan showed in the third duodenal segment the presence of inflammatory tissue with air bubbles between the duodenum and prosthesis, adherent to the duodenum. The patient was submitted to surgery, during which the prosthesis was detached from the duodenum, the intestine failed to close and a ga…

Initial Experience with Radical Prostatectomy Following Holmium Laser Enucleation of the Prostate

2021

Background: Although an increasing number of prostate cancer (PCa) patients received holmium laser enucleation of the prostate (HoLEP) previously for benign prostatic obstruction (BPO), there is still no evidence regarding the outcomes of radical prostatectomy (RP) in this setting. Objective: To assess functional and oncological results of RP in PCa patients who received HoLEP for BPO previously in a contemporary multi-institutional cohort. Design, setting, and participants: A total of 95 patients who underwent RP between 2011 and 2019 and had a history of HoLEP were identified in two institutions. Functional as well as oncological follow-up was prospectively assessed and retrospectively an…

Ileocecal duplication cysts: is the loss of the valve always necessary?

2014

Abstract Background Ileocecal (IC) duplication cysts are enteric duplications located at the IC junction, not clearly identified in all the published series. The reported treatment is IC resection and ileocolic anastomosis. It is well known that the loss of the IC valve has several adverse effects. This study is aimed at demonstrating that cyst removal together with the common ileal wall and following enterorrhaphy is possible, safe, and effective in preserving the IC region. Methods Medical records of 3 patients who underwent surgery for IC duplication between 2003 and 2013 were retrospectively reviewed evaluating follow-up results. Results All patients had an antenatal diagnosis of intraa…
