Histology profiling of lung tumors: tru-cut versus full-core system for CT-guided biopsies.

Purpose: We aimed to compare the diagnostic yield and procedure-related complications of two different types of systems for percutaneous CT-guided lung biopsy.

Material And Methods: All patients with a lung lesion who underwent a CT-guided lung biopsy at our institution, between January 2019 and 2021, were retrospectively analyzed. The inclusion criteria were: (a) Procedures performed using either a fully automated tru-cut or a semi-automated full-core biopsy needle, (b) CT images demonstrating the position of the needles within the lesion, (c) histopathological result of the biopsy and (d) clinical follow-up for at least 12 months and\or surgical histopathological results.

Diagnostic yield of CT-guided lung biopsies: how can we limit negative sampling?

Objectives: To investigate whether lesion imaging features may condition the outcome of CT-guided lung biopsy (CTLB) and to develop a scoring system of biopsy outcome prediction.

Methods: This is a single center retrospective study on 319 CTLBs that were performed in 319 patients (167 males/152 females, mean age 68 ± 12.2).

New ePTFE/FEP-covered stent in the palliative treatment of malignant biliary obstruction.

Purpose: To determine the technical efficacy and safety of an expanded polytetrafluoroethylene and fluorinated ethylene propylene (ePTFE/FEP)-covered metallic stent in the management of malignant biliary obstruction and to evaluate its clinical efficacy by estimating stent patency and patient survival rates.

Materials And Methods: Twenty-six patients with common bile duct stricture caused by malignant disease were treated by placement of 29 stents. The stent consists of an inner ePTFE/FEP lining and an outer supporting structure of nitinol wire.

Tension-free laparoscopic and open hernia repair: randomized controlled trial of early results.

The aim of the study was prospectively to compare the early results and outcome in 105 patients randomly allocated to undergo tension-free laparoscopic hernia repair (LHR) with transabdominal preperitoneal technique (53 patients) or open hernia repair (OHR) with mesh apposition (52 patients). The mean (SD) operation time was longer in the LHR group than in the OHR group: 49.6 (5.

Jejunal interposition for peptic stenosis of the esophagus following esophagomyotomy for achalasia.

Retrospective analysis of the results of esophagojejunogastrostomy in 21 patients with peptic stenosis after esophagomyotomy for achalasia is reported. All patients complained of severe dysphagia. The esophagogram showed the presence of a 2 to 3 cm long stenosis in the lower esophagus with a diameter < 10 mm.
