Endoscopic diagnosis of gastric metastases from malignant melanoma: systematic review.

Background/aims: Metastases of malignant melanoma (MM) are rare and associated with poor prognosis. The objective of this study was to analyze the clinical and endoscopic characteristics of gastric metastases of MM by systematically reviewing cases and case series involving patients diagnosed using upper gastrointestinal endoscopy.

Methods: The PubMed and LILACS databases were searched.

Effect of the introducer technique compared with the pull technique on the peristomal infection rate in PEG: a meta-analysis.

Background: Peristomal infection is a main complication of PEG. The pull technique appears to be associated with higher infection rates compared with the introducer technique, although published results are controversial.

Objective: To determine which technique is associated with a higher risk of infection.

Peristomal infection in percutaneous endoscopic gastrostomy (PEG): a comparative study of two gastropexy techniques in a before-and-after design.

Introduction: Percutaneous endoscopic gastrostomy (PEG) performed using the Pull technique is associated with a high rate of surgical infections. When PEG is performed using the Introducer technique, a lower rate of infection is seen. However, this technique can pose technical difficulties during gastropexy.
