Virtual Reality Simulator Training of Laparoscopic Cholecystectomies — A Systematic Review

2012

Background and Aims: Simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. Surgical procedures can be simulated by increasingly complex and expensive techniques. This review gives an update on computer-based virtual reality (VR) simulators in training for laparoscopic cholecystectomies. Materials and Methods: From leading databases (Medline, Cochrane, Embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. Twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. Furthermore, seven studies comparing black…

Gnotobiotische untersuchungen an SPF-Mäusen im rahmen einer studie zur tumorentwicklung im kolon nach cholezystektomie

1985

Summary The relation between cholecystectomy and colon carcinogenesis has not been fully elucidated. As bacteria may be involved in the carcinogenic process, we investigated the effect of cholecystectomy and dimethylhydrazine (DMH) administration to SPF NMRI mice with regard to tumour genesis and bacterial colonisation of the intestine. It results from this study that cholecystectomy does not influence tumour genesis and that 6–7 months post operationem and DMH administration tumours and bacteria originally not found in the animals develop: Clostridia, eubacteria spec, which cannot be differentiated and E. lentum. Theses changes appear in group II of mice (laparotomy and DMH) and group III …

Impact of stage migration on bladder cancer: A slow but steady improvement in the long term survival rates after radical cystectomy in the last 25 ye…

2016

INTRODUCTION & OBJECTIVES: Bladder cancer (BCa) is a heterogeneous disease with up to 25% of incidental diagnoses reported to be found muscle invasive at first episode. Numerous markers and an increased awareness have been recorded in the recent years. We sought to evaluate if those considerat ions may determine a change in BCa clinical presentation at radical cystectomy (RC) over years in a single high volume tert iary referral center. MATERIAL & METHODS: The study relied on 2,003 consecutive BCa pat ients treated with RC and extended pelvic lymphadenectomy (PLND) at a single inst itution between January 1990 and December 2014. Pat ients were st ratified into tertiles according to …

Mirizzi syndrome type V complicated with both cholecystobiliary and cholecystocolic fistula: a case report

2021

Abstract Mirizzi syndrome (MS) is a common bile duct (CBD) obstruction caused by extrinsic compression from an impacted stone in the cystic duct or infundibulum of the gallbladder. Patients affected by MS may present abdominal pain and jaundice. A 37-year-old male with neurologic residuals post-encephalitis arrived at the emergency department reporting abdominal pain, jaundice and fever. An ultrasound of the abdomen identified cholecystolithiasis with a dilated CBD. He did not undergo CT or MRI due to poor compliance and parents’ disagreement. Eventually, they accepted to perform endoscopic retrograde cholangiopancreatography, which diagnosed MS with both cholecystobiliary and cholecystocol…

T1HG Bladder Tumours: So Many Papers, Do We Need Them? Yes, We Do!

2009

“How many roads a man must walk on….” and how many papers we must read and write… to put down the final word on the appropriate management of high risk NMI-BC. Although it is more than 20 years that we take notice of promises on biological markers predictive of the behaviour of NMI-BC, till today we can only base our decisions on clinical and pathological data. Consequently, we need exchange of experiences and reports on the outcome of these patients. The aim of the treatment of T1 bladder tumours is to minimize mortality while assuring reduced morbidity and good quality of life. A conservative approach is, obviously, not applicable to all T1HG tumours. We need to identify unequivocal selec…

Long-term results of ileocecal continent urinary diversion in patients treated with or without previous pelvic irradiation

2003

Purpose: Patients who receive pelvic irradiation may require urinary diversion to manage complications resulting from progressive malignancy or radiotherapy. The choice of urinary diversion is an important issue and remains controversial. We characterized the long-term outcome of urinary diversion with a continent ileocecal reservoir in patients who received pelvic irradiation versus those who underwent urinary diversion without previous irradiation. Materials and Methods: Continent urinary diversion with an ileocecal reservoir (Mainz pouch 1) was performed in 36 irradiated patients in a 9-year period. Morbidity, mortality, the reoperative rate and parameters associated with the surgical pr…

Clinical Scenario: Unexpected Positive Nodes at Radical Cystectomy

2014

Positive lymph nodes are found in 20–30 % of patients undergoing radical cystectomy for bladder cancer. Their presence is associated with poor survival in the majority. Super-extended lymph node dissection is recommended in the presence of positive lymph nodes to possibly improve oncologic outcome. In patients with unsuspicious lymph nodes, dissection should be performed at least up to the common iliac vessels. Even in the presence of lymph node metastases cystectomy is indicated to reduce local tumor complications. The type of urinary diversion should not be altered by lymph node positivity unless the diversion would otherwise negatively influence the extent of the procedure.
