Ureterosigmoidostomy: an outdated approach to bladder exstrophy?
1990
Long-term results among 46 children with ureterosigmoidostomy are presented. The indication for ureterosigmoidostomy had been bladder exstrophy in 40 patients, incontinent epispadias in 5 and neurogenic bladder dysfunction in 1. Of the 40 patients with bladder exstrophy 8 had undergone ureterosigmoidostomy after failure of other types of urinary tract reconstruction (6 had upper tract dilatation before ureterosigmoidostomy). Three patients with previously damaged upper urinary tracts required early postoperative conversion because of severely increasing kidney dilatation. Three other patients required conversion after a mean of 10 years to preserve kidney function. One patient died after 16…
Hepatopulmonary Syndrome in a Patient With Adenocarcinoma of the Colon Metastatic to the Liver and No Apparent Chronic Liver Disease
2006
Hepatopulmonary syndrome consists of a clinical triad: arterial blood deoxygenation, intrapulmonary vasodilation, and liver disease. Both acute and chronic cases of this syndrome have been reported, and the most common cause is cirrhosis. The principle disease mechanism is dilation of the pulmonary blood vessels causing alterations in gas exchange. Increased pulmonary production of nitric acid has been implicated as the primary pathogenic mechanism of vasodilation although it has also been associated with imbalance between vasodilators and vasoconstrictors. We describe the case of a patient with hepatopulmonary syndrome and adenocarcinoma of the colon with metastases to a previously healthy…
Unexplained neoplastic anastomotic recurrence after right hemicolectomy: a case report
2020
Abstract Background Anastomotic recurrences of the colon are postulated to arise due to inadequate margins, tumor implantation by exfoliated cells, altered biological properties of bowel anastomosis, and missed synchronous lesions. In this paper, a case of unexpected early local recurrence after surgery for colon cancer is presented. Case presentation A 68-year-old Caucasian man underwent right hemicolectomy for invasive G2 adenocarcinoma. Two months later, endoscopy revealed a wide and well-functioning anastomosis with a hyperemic, hard, and thickened mucosal area of about 2 cm in diameter. Biopsies showed the presence of an adenocarcinoma with the same grading of the previous lesion. Ten …
Predictors of complications and mortality following left colectomy with primary stapled anastomosis for cancer: results of a multicentric study with …
2018
Aim Reports detailing the morbidity-mortality after left colectomy are sparse and do not allow definitive conclusions to be drawn. We aimed to identify risk factors for anastomotic leakage, perioperative mortality and complications following left colectomy for colonic malignancies. Method We undertook a STROBE-compliant analysis of left colectomies included in a national prospective online database. Forty-two variables were analysed as potential independent risk factors for anastomotic leakage, postoperative morbidity and mortality. Variables were selected using the 'least absolute shrinkage and selection operator' (LASSO) method. Results We analysed 1111 patients. Eight per cent of patient…
First hospital contact via the Emergency Department is an independent predictor of overall survival and disease-free survival in patients with colore…
2019
espanolObjeto: el objetivo del presente estudio es examinar la asociacion entre el tipo de admision hospitalaria, la supervivencia y las caracteristicas patologicas de una amplia poblacion de pacientes con cancer colorrectal. Metodos: realizamos un estudio en 1.079 pacientes diagnosticados en el Hospital Costa del Sol de Marbella con cancer colorrectal y evaluamos la relacion entre su tasa de supervivencia y la via por la que realizaron el primer contacto con el hospital (admision programada o de urgencias). Las variables incluidas en nuestro estudio fueron las siguientes: edad, genero, localizacion del tumor, estadio patologico, grado de diferenciacion, quimioterapia previa a la cirugia y …
Fecal Blood Loss in Patients With Colonic Polyps: A Comparison of Measurements With 51Chromium-Labeled Erythrocytes and With the Haemoccult Test
1982
Abstract The quantitative determinations of fecal daily blood loss after intravenous administration of 51Cr-labeled erythrocytes in 44 patients with colonic polyps and in 11 controls were compared with the results of the daily performed Haemoccult test without dietary restrictions. A total of 642 stool specimens was analyzed for 51Cr loss and the Haemoccult test. The mean fecal daily blood loss in the 34 patients with adenomatous polyps of the descending colon and rectosigmoid was 1.36 ± 0.14 ml/day (mean ± SEM), in the 10 patients with polyps of the ascending and transverse colon it was 1.28 ± 0.31 ml/day, and in the 11 controls 0.62 ± 0.07 ml/day. There was no positive Haemoccult test in …
Risk Factors for Anastomotic Leak After Colon Resection for Cancer
2015
To determine pre-/intraoperative risk factors for anastomotic leak after colon resection for cancer and to create a practical instrument for predicting anastomotic leak risk.Anastomotic leak is still the most dreaded complication in colorectal surgery. Many risk factors have been identified to date, but multicentric prospective studies on anastomotic leak after colon resection are lacking.Fifty-two hospitals participated in this prospective, observational study. Data of 3193 patients, operated for colon cancer with primary anastomosis without stoma, were included in a prospective online database (September 2011-September 2012). Forty-two pre-/intraoperative variables, related to patient, tu…
Individual surgeon is an independent risk factor for leak after double-stapled colorectal anastomosis: An institutional analysis of 800 patients
2017
Background. Our aim was to assess whether the individual surgeon is an independent risk factor for anastomotic leak in double-stapled colorectal anastomosis after left colon and rectal cancer resection. Methods. This retrospective analysis of a prospectively collected database consists of a consecutive series of 800 patients who underwent an elective left colon and rectal resection with a colorectal, double-stapled anastomosis between 1993 and 2009 in a specialized colorectal unit of a tertiary hospital with 7 participating surgeons. The main outcome variable was anastomotic leak, defined as leak of luminal contents from a colorectal anastomosis between 2 hollow viscera diagnosed radiologic…
Patterns of recurrence of obstructing colon cancers after surgery for cure: a population-based study.
2013
Aim Little is known about patterns of recurrence in obstructing colon cancer (OCC) at a population level. The aim of this study was to determine the risk of recurrence following potentially curative surgery in OCC compared with that in uncomplicated colon cancer (CC). Method Data were obtained from the population-based digestive cancer registry of Burgundy (France). Local and distant failure rates were calculated using actuarial methods. A multivariate analysis was performed using a Cox model. Results Obstructing colon cancer represented 8.5% of all colon cancers resected with curative intent (n = 3375). The 5-year cumulative local recurrence rate was 14.2% for OCC and 7.6% for nonobstructi…
Chemotherapy of metastatic colon cancer in France: A population-based study
2021
International audience; Aims: to describe, using data from a cancer registry in a well-defined French population, the therapeutic strategies and survival of patients with metastatic colon cancer (mCC).Methods: all patients with synchronous mCC diagnosed within the 2005-2014 period recorded in the digestive cancers registry of Burgundy were included.Results: 1286 mCC patients were included (57% male), of which 34.5% did not receive any antitumor treatment. Both, advanced age (≥75 years) and the Charlson comorbidity score ≥2 were significantly associated with the absence of antitumor treatment. Among the patients treated with chemotherapy, 59 and 33% received at least two and three lines, res…
