Colonic stenting as a bridge to surgery in malignant large-bowel obstruction: a report from two large multinational registries.

Objectives: To date, this is the largest prospective series in patients with malignant colorectal obstruction to evaluate the effectiveness and safety of colonic self-expanding metal stents (SEMSs) as an alternative to emergency surgery. SEMSs allow restoration of bowel transit and careful tumor staging in preparation for elective surgery, hence avoiding the high morbidity and mortality associated with emergency surgery and stoma creation.

Methods: This report is on the SEMS bridge-to-surgery subset enrolled in two multicenter international registries.

Self-expandable metal stents for relieving malignant colorectal obstruction: short-term safety and efficacy within 30 days of stent procedure in 447 patients.

Background: The self-expandable metal stent (SEMS) can alleviate malignant colonic obstruction and avoid emergency decompressive surgery.

Objective: To document performance, safety, and effectiveness of colorectal stents used per local standards of practice in patients with malignant large-bowel obstruction to avoid palliative stoma surgery in incurable patients (PAL) and facilitate bowel decompression as a bridge to surgery for curable patients (BTS).

Design: Prospective clinical cohort study.

The global impact of endoscopic ultrasound (EUS) regarding the survival of a pancreatic adenocarcinoma in a tertiary hospital.

Background: Pancreatic ductal adenocarcinoma is a type of neoplasm with a high mortality rate. There are a number of different procedures that may be followed in the study of the pancreas; one such procedure is endoscopic ultrasonography (EUS).

Objective: This study aimed to retrospectively evaluate the impact on patient survival of a biliopancreatic EUS performed 2 months prior to the first treatment session of the pancreatic ductal adenocarcinoma.
