Simplified orthotopic ileocaecal pouch (Mainz pouch) for bladder substitution

The use of operative ultrasonography for the localization of renal calculi.

1987

The ultrasonically guided nephrotomy technique using B-scanning to identify the localization of stones and Doppler sonography to identify avascular parenchymal areas for nephrotomies allows for transparenchymal stone removal without the need for renal artery clamping and renal cooling. In 175 procedures the average blood loss was 1,350 ml and the rate of residual stones requiring a secondary intervention was 2.8%. Despite the advent of new noninvasive treatment modalities, this technique is still applied in 23% of staghorn stones.

Targeting Moderate and Severe Male Stress Urinary Incontinence With Adjustable Male Slings and the Perineal Artificial Urinary Sphincter: Focus on Pe…

2017

Purpose: To analyze perioperative complications and postoperative explantation rates for selected readjustable male sling systems and the perineal single-cuff artificial urinary sphincter (AUS) in a large, contemporary, multi-institutional patient cohort. Methods: Two hundred eighty-two male patients who underwent implantation between 2010 and 2012 in 13 participating institutions were included in the study (n = 127 adjustable male sling [n = 95 Argus classic, n = 32 Argus T], n = 155 AUS). Perioperative characteristics and postoperative complications were analyzed. The explantation rates of the respective devices were assessed using the Fisher exact test and the Mann-Whitney U-test. A Kapl…

Transperitoneal vs retroperitoneal minimally invasive partial nephrectomy: comparison of perioperative outcomes and functional follow-up in a large m…

2020

Abstract Background Aim of this study was to evaluate and compare perioperative outcomes of transperitoneal (TP) and retroperitoneal (TR) approaches in a multi-institutional cohort of minimally invasive partial nephrectomy (MI-PN). Material and methods All consecutive patients undergone MI-PN for clinical T1 renal tumors at 26 Italian centers (RECORd2 project) between 01/2013 and 12/2016 were evaluated, collecting the pre-, intra-, and postoperative data. The patients were then stratified according to the surgical approach, TP or RP. A 1:1 propensity score (PS) matching was performed to obtain homogeneous cohorts, considering the age, gender, baseline eGFR, surgical indication, clinical dia…

Robotic Hysterectomy in Severely Obese Patients With Endometrial Cancer: A Multicenter Study

2015

Abstract Study Objective The aim of this study was to evaluate the surgical and oncologic outcomes of robotic hysterectomy with or without or less pelvic and aortic lymphadenectomy in severely obese patients (body mass index [BMI] ≥ 40 kg/m 2 ) with endometrial cancer. Material and Methods Between August 2010 and November 2014, patients with histologically confirmed endometrial cancer and BMI ≥40 kg/m 2 were deemed eligible for the study and underwent RH with or without pelvic and aortic lymphadenectomy. Results Seventy patients were divided into 3 groups according to their BMI: group A, BMI between 40 and 45 kg/m 2 (50 patients); group B, BMI between 45 and 50 kg/m 2 (10 patients); and gro…

Transperitoneal versus extraperitoneal laparoscopic aortic lymph nodal staging for locally advanced cervical cancer: A systematic review and meta-ana…

2021

Abstract Cervical cancer is the fourth most common neoplasm in women. In locally advanced cervical cancers, the international guidelines recommend nodal aortic assessment. Two techniques have been described to perform laparoscopic aortic lymphadenectomy: transperitoneal laparoscopic lymphadenectomy (TLL) and extraperitoneal laparoscopic lymphadenectomy (ELL). This meta-analysis aims to compare the surgical outcomes of TLL and ELL for staging purposes. The systematic review was carried out in agreement with the preferred reporting items for systematic reviews and meta-analyses statement (PRISMA). Two hundred and twenty studies were analyzed, and 19 studies were included in the review (7 for …

Isolated Pediatric Intramedullary Schwannoma: Case Report and Review of Literature

2018

Background: Intramedullary (IM) schwannomas are rare entities representing 0.3%−1% of intramedullary tumors and 1.1% of spinal schwannomas. Beside many theories proposed, their rare occurrence might be related to the absence of Schwann cells in the spinal cord. Pediatric IM schwannomas are uncommon, and in the absence of neurofibromatosis they are extremely rare. To date, few cases have been reported in the literature. Case Description: We describe the case of an 8-year-old female affected by a progressive paraparesis. Neuroradiologic investigations showed an oval-shaped mass at the level of T10-T11. The patient underwent surgery, performed under neurophysiologic monitoring. The patient was…

Coplanar Indirect-Navigated Intraoperative Ultrasound: Matching Un-navigated Probes With Neuronavigation During Neurosurgical Procedures. How We Do I…

2021

BACKGROUND Intraoperative ultrasound (IOUS) is becoming more and more adopted in neurosurgery, since it has been associated to greater extent of resection (EOR) and to gross total resection (GTR) during brain tumor surgery. IOUS main limitations are spatial resolution, width and orientation of the field of view and scan quality, which are operator-dependent. Furthermore, most neurosurgeons are not confident with this technique, which needs a long learning curve in order to identify and interpret anatomic structures. OBJECTIVE To describe an effective procedure to take advantages of both IOUS and neuronavigation in case of lack of a navigated ultrasound system. METHODS We propose a reliable …

Communal data work: Data sharing and re-use in clinical genetics

2019

In this article, we examine work with communal data in the context of clinical genetic testing. Drawing from prior research on digital research infrastructures and from the analysis of our empirical data on genetic testing, we describe how data generated in laboratories distributed all over the world are shared and re-used. Our research findings point to six different human-driven activities related to expanding, disambiguating, sanitizing and assessing the relevance, validity and combinability of data. We contribute to research within Health Informatics with a framework that foregrounds human-driven activities for data interoperability.

Novel Device for Endoluminal Esophageal Atresia Repair: First-in-Human Experience

2021

Thoracoscopic esophageal atresia (EA) repair affords many benefits to the patient; however, intracorporeal suturing of the anastomosis is technically challenging. Esophageal magnetic compression anastomosis (EMCA) is a compelling option for endoluminal EA repair, but available EMCA devices have prohibitive rates of recalcitrant stricture. Connect-EA is a new endoluminal EMCA device system that employs 2 magnetic anchors with a unique mating geometry designed to reliably create a robust anastomosis and decrease rates of leak and stricture. We describe our first-in-human experience with this novel endoluminal device for staged EA repair in 3 patients (Gross type A, B, and C) at high risk for …
