Cryoablation for treatment of peripheral lung metastases from colorectal cancer: a bicenter retrospective study.

Objectives: To evaluate the oncological efficacy and complications of cryoablation (CA) in treating lung metastases from colorectal cancer (CRC) at the lung periphery.

Materials And Methods: The inclusion criteria for this bicenter retrospective study included patients with histologically confirmed CRC, with radiologically confirmed lung metastases at the periphery of the lung (distance of less than or equal to 2 cm from the costal, diaphragmatic, or cervical pleura) treated with CA between January 2017 and June 2022. Patients with intra-parenchymal metastases or metastases close to the mediastinal pleura and patients without follow-up were excluded.

Evaluation of preventive tract embolization with standardized gelatin sponge slurry on chest tube placement rate after CT-guided lung biopsy: a propensity score analysis.

Background: To evaluate the effect of tract embolization (TE) with gelatin sponge slurries during a percutaneous lung biopsy on chest tube placement and to evaluate the predictive factors of chest tube placement.

Methods: Percutaneous CT-guided lung biopsies performed with (TE) or without (non-TE) tract embolization or between June 2012 and December 2021 at three referral tertiary centers were retrospectively analyzed. The exclusion criteria were mediastinal biopsies, pleural tumors, and tumors adjacent to the pleura without pleural crossing.

Preoperative liver arterial conditioning in patients scheduled for a Mayo Clinic class Ia distal pancreatectomy: embolization or ligation?

Background: Liver ischemia may occur during intraoperative common hepatic artery ligation in Mayo Clinic class I distal pancreatectomy with en bloc celiac axis resection (DP-CAR). Preoperative liver arterial conditioning could be used to avoid this outcome. This retrospective study compared arterial embolization (AE) or laparoscopic ligation (LL) of the common hepatic artery before class Ia DP-CAR.

Transarterial chemoembolization (TACE) for neuroendocrine liver metastasis (NELM): Predictive value of volumetric arterial enhancement (VAE) on baseline MRI.

Background: Neuroendocrine tumors (NETs) belong to a rare family of tumors whose incidence has increased significantly over the past 50 years.

Purpose: To evaluate the prognostic value of volumetric arterial enhancement (VAE) on baseline magnetic resonance imaging (MRI) for patients with neuroendocrine liver metastasis (NELM) treated using transarterial chemoembolization (TACE).

Material And Methods: Between October 2012 and December 2018, VAE in 37 patients was measured with a semi-automatic volume of Interest (VOI) on subtracted T1 sequence in the arterial phase.
