Predictors of Early Distant Relapse in Rectal Cancer Patients Submitted to Preoperative Chemoradiotherapy.

Background: Neoadjuvant chemoradiotherapy (CRT) is a standard treatment for locally advanced rectal cancer. CRT leads to a better local control; however, this does not translate into a survival benefit. Long-term survival is mostly affected by the development of distant metastases after surgery.

Comparative use of different techniques for leak and bleeding prevention during laparoscopic sleeve gastrectomy: a multicenter study.

Background: Laparoscopic sleeve gastrectomy (LSG) is an approved primary procedure for morbid obesity, but it is associated with serious complications, such as staple line leaks and bleeding. The objective of this study was to assess the effectiveness of staple line reinforcement (SLR) in reducing leaks and bleeding after LSG.

Methods: A total of 1162 patients underwent LSG (305 males, 857 females).
