Use of absorbable meshes in laparoscopic paraesophageal hernia repair.

Paraesophageal hernia (PEH) repair is one of the most challenging upper gastrointestinal operations. Its high rate of recurrence is due mostly to the low quality of the crura and size of the hiatal defect. In an attempt to diminish the recurrence rates, some clinical investigators have begun performing mesh-reinforced cruroplasty with nonabsorbable meshes like polypropylene or polytetrafluoroethylene.

(18)F-FDG uptake by rectal cancer is similar in mucinous and nonmucinous histological subtypes.

Purpose: PET/CT has been considered limited for the evaluation of mucinous colorectal tumors due to low (18)F-FDG uptake. The aim of our study was to compare PET/CT variables in mucinous (MC) and nonmucinous (NMC) rectal adenocarcinomas.

Methods: Consecutive patients with cT2-4N0-2M0 rectal cancer included in a prospective clinical trial were reviewed.
