OBJECTIVE: The aim of this study was to evaluate the feasibility of robotic extravesical posterior surgical bladder diverticulectomy for treatment of symptomatic bladder diverticula (BD). MATERIALS AND METHODS: Data from patients with posterior BD who consecutively underwent robotic bladder diverticulectomy (RBD) from 2013 to 2016 in Azienda Ospedaliera Universitaria Integrata, Verona, were retrospectively reviewed. Baseline characteristics, perioperative outcomes including operative time (OT), estimated blood loss (EBL), postoperative transfusion rate and length of hospital stay (LOS), and early (30 days) and late (90 days) postoperative complications were recorded and analysed...

Pancreatic cancer (PC) is one of the deadliest cancers with a 5-year overall survival of less than 6%. Due to its insidious clinical course and unspecific symptoms, the diagnosis is usually late, with only 15-20% patients presenting with potentially curable disease. It is, therefore, extremely important to identify patients with PC at early stages of the disease when tumors may be amenable to surgical resection. For unresectable and borderline resectable PC it is consensual to perform a biopsy to have a cyto/histological confirmation of malignancy before treatment...

Prostate cancer remains the only solid tumor diagnosed using transrectal ultrasound-guided sampling of the gland, and not an image-based, lesion-directed approach. This technique has limitations in that it underdiagnoses clinically significant disease and overdiagnoses indolent tumors resulting in overtreatment of patients. Technical advances in MRI in the last decade have made this method the preferred imaging modality for prostate anatomy and for risk assessment of prostate cancer. As of 2018, the indications for MRI in the diagnosis and risk assessment of prostate cancer have expanded from preoperative evaluation to the pre-biopsy setting, as well as for surveillance protocols...

PURPOSE: This study aims to evaluate the link between preoperative parameters and oxidative stress (OS) markers in the bladder wall of men undergoing open prostatectomy. MATERIALS AND METHODS: From July 2014 to August 2016, men aged ≥ 50 years and presenting with LUTS were prospectively enrolled. Preoperative assessment included validated questionnaires (IPSS and OAB - V8), lower urinary tract ultrasound and urodynamics. Bladder biopsies were taken during open prostatectomy for determination of OS markers...

Ultrasound-guided wire localization (USGWL) was originally developed for the removal of impalpable breast lesions. More recently, USGWL has been described in head and neck surgical practice and it has a number of applications in this field, with the potential to guide surgical exploration and the benefits of reducing operative time and morbidity. This technical note describes the use of preoperative USGWL to facilitate the removal of an impalpable neck node. A review of the current literature relating to the present applications of this technique in head and neck surgery is reported, highlighting its advantages and disadvantages...

OBJECTIVE: We aimed to compare routine preoperative color-coded duplex ultrasound (DUS) to clinical examination (CE) alone in surgery for arteriovenous fistula (AVF) with special emphasis on long-term outcomes and cost effectiveness. METHODS: All patients undergoing an AVF formation or revision between January 1, 2011, and December 31, 2016, at our tertiary referral center were subject to analysis. Routine DUS was performed in 114 patients and CE alone in 217 patients...

RATIONALE: Arterial occlusion, a rare condition after total knee arthroplasty (TKA), may cause fatal outcomes if not treated on time. We report a case of arterial occlusion after undergoing navigated TKA with no tourniquet use, in a patient at high risk of postoperative arterial occlusion due to the patient's ipsilateral popliteal artery aneurysm. PATIENTS CONCERNS: A 79-year-old man presented with several years of left knee joint pain. Nine years earlier, the patient underwent vascular graft surgery on his right knee due to occlusion in his right popliteal artery...

Recent advance in bronchology and interventional pulmonology contributes to improve the quality of patient care in thoracic surgery. Narrow band imaging (NBI) combined with high definition bronchoscopy clearly visualize the aberrant tumor vessels on the mucosa of endobronchial malignancy. It helps the preoperative surgical planning for the clear bronchial margin during the surgery. The index of hemoglobin (IHb) show the approximate amount of hemoglobin within the mucosal surface and we use the IHb for the evaluation of local circulation of bronchial anastomosis after bronchoplasty...

BACKGROUND: Massive and irreparable rotator cuff tears are difficult to manage surgically. One technique is to use a synthetic polytetrafluoroethylene (PTFE) patch to bridge the tear. However, there is little information regarding the outcomes of this procedure. PURPOSE: To determine the ≥2-year outcomes of patients for whom synthetic patches were used as tendon substitutes to bridge irreparable rotator cuff defects. STUDY DESIGN: Case series; Level of evidence, 4...

BACKGROUND: Post-operative pancreatic fistulae (POPF) remain a major contributor to morbidity and mortality following pancreatic resection. Evidence for preoperative prediction of POPF based on cross-sectional imaging has not been systemically reviewed. This review aimed to determine whether preoperative imaging modalities can accurately predict the development of POPF. METHODS: A systematic review of major reference databases was undertaken, according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, up to May 2018...

BACKGROUND: At the time of diagnosis, one-third of medullary thyroid carcinoma (MTC) patients show lymph node (LN) or distant metastasis. A metastasized MTC requires different surgical strategies. OBJECTIVE: This study aimed to determine the value of ultrasound and [18F]fluoro-dihydroxyphenylalanine positron emission tomography with computed tomography (F-DOPA-PET-CT) in localizing MTC, as well as LN and distant metastasis. METHODS: The study included 50 patients (24 males/26 females) with preoperative ultrasound, F-DOPA-PET-CT, and histologically proven MTC...

BACKGROUND: To compare the ciliary body changes associated with the use of 23-gauge (23G) and 20-gauge (20G) systems for pars plana vitrectomy. METHODS: A total of 60 patients (60 eyes) with idiopathic epiretinal membrane who were scheduled for surgical treatment were selected and randomly assigned to 20G group or 23G group. Time required for incision making, vitrectomy, and incision closure was compared between the two groups. Changes in ciliary body were evaluated by ultrasound microscopy (UBM)...

Reports on pacemaker placement/relocation surgery under pectoralis nerve block are limited. We herein report a case involving a 74-year-old woman with an infected cardiac pacemaker generator who underwent pacemaker relocation surgery under an ultrasound-guided pectoralis nerve block. On preoperative evaluation, she had congestive heart failure, type 2 diabetes mellitus, and a pacer-dependent heart rhythm. She was considered to be at high risk for general anesthesia. Thus, an ultrasound-guided pectoralis nerve block was planned...

Background: The gold standard treatment of symptomatic cholelithiasis is videolaparoscopic cholecystectomy (VLC). The aim of this study is to produce a predictive clinical ultrasound (US) score for difficult VLC to reduce the rate of conversion to open cholecystectomy surgery and intra and/or post-operative complications. Methods: In this prospective study carried out in 2017 we enrolled 135 patients (pts) who underwent VLC in our General Surgery Unit. A specific pre-operative abdominal ultrasound scan was performed to assess gallbladder characteristics for each patient...
