8 A multicentric randomized trial to evaluate the role of uterine manipulator on laparoscopic/robotic hysterectomy for the treatment of low-risk endo…

2020

Background The role of the intrauterine manipulator in minimally invasive hysterectomy for endometrial cancer has been widely debated in terms of impact on the oncological outcomes. To date, definitive conclusions on the possible advantages and oncological safety of its use in endometrial cancer staging are still awaited. Objectives This randomized trial aimed to assess the role of the uterine manipulator in terms of oncological and perioperative outcomes in patients undergoing minimally invasive (laparoscopic/robotic) staging for presumed low-risk endometrial cancer. Study Design Enrolled patients were randomly allocated in two groups according to the use (Group A) or no use (Group B) of t…

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…

�nderungen des Elektrolytgehalts von Erythrocyten und Plasma bei nephrektomierten Ratten

1957

After two-stage nephrectomy in rats the potassium concentration in the red blood corpuscles (RBC) decreases from 10.6 ± 0.3 to 5.5 ± 0.3 mEq per 100 ml of RBC within 48 h. The decrease is accompanied by a much smaller increase in the plasma potassium concentration; the hyperkaliemia in nephrectomized rats is less pronounced than in nephrectomized dogs or anuric humans. Na+ in RBC increases by about 44% after nephrectomy; while there is only a very slight decrease of Na+ in plasma. Plasma chlorides drop from 10.92 ± 0.08 mEq/100 ml of plasma to 6.00 ± 0.81 mEq % within 48 h after nephrectomy. RBC chlorides tend to increase again after an initial drop from 5.22 ± 0.07 to 3.82 ± 0.90 mEq% with…

Conservative Surgery of Renal Tumors: Operative Technique, Complications, Results, DNA Cytometry

1992

Until now radical nephrectomy has been regarded as the standard therapy for nonmetastasized renal cell carcinoma. This operation has been accepted because of the theoretical advantage of a more complete resection. A parenchyma-sparing operation was only performed in patients in whom radical nephrectomy would result in renal failure requiring hemodialysis (imperative indication), such as patients with single kidney, bilateral tumors, dysfunctional contralateral kidney, or chronic renal failure. However, the widely used partial nephrectomy in these instances may in certain cases result in insufficient residual renal parenchyma. Simple enucleation of the tumor with a small surrounding margin o…

Surgical sphincter saving approach and topical nifedipine for chronic anal fissure with hypertonic internal anal sphincter

2020

PURPOSE The role of augmented internal anal sphincter (IAS) tone in the genesis of posterior chronic anal fissure (CAPF) is still unknown. Lateral internal sphincterotomy is the most employed surgical procedure, nevertheless it is burdened by high risk post-operative anal incontinence. The aim of our study is to evaluate results of sphincter saving procedure with post-operative pharmacological sphincterotomy for patients affected by CAPF with IAS hypertonia. Methods: We enrolled 30 patients, undergone fissurectomy and anoplasty with V-Y cutaneous flap advancement; all patients received topical administration of nifedipine 0.3% and lidocaine 1.5% ointment-based therapy before and for 15 days…

Surgical treatment of chronic thromboembolic pulmonary hypertension.

2006

Chronic thromboembolic pulmonary hypertension is a commonly overlooked cause of physical incapacity and dyspnoea, with a higher incidence than is generally appreciated and a poor prognosis. The diagnosis can be suspected based on echocardiographic examinations and ventilation perfusion scanning of the lung. Pulmonary angiography still remains the gold standard for the diagnosis of thromboembolic pulmonary hypertension and the assessment of operability. Pulmonary endarterectomy is a complex surgical procedure, which provides permanent relief of thromboembolic pulmonary hypertension and cure for most of the patients. The operation resembles a true endarterectomy of the pulmonary artery branch…

Risk Assessment for Complications of Partial Nephrectomy – Comparative Study between Retroperitoneoscopic Approach and Open Surgery

2017

Introduction. Partial nephrectomy represent the standard of care for small renal tumor. Laproscopic approach tends to replace open surgery due to similar oncologic results, but with better eastethic outcomes and earlier socio-professional reintegration. Material and methods. Between January 2010 and February 2017, 55 patients (p) underwent partial nephrectomy at our center for clinically localized renal tumor, 21p with LPN by retroperitoneal approach and 34p with OPN. All patients had a normal contralateral kidney. The selection of patients for nephron-sparing surgery was based on preoperative CT scan, location of the tumor, the individual general health status of the patient and individual…
