Near-infrared fluorescence cholangiography at a very low dose of indocyanine green: quantification of fluorescence intensity using a colour analysis software based on the RGB color model.

Background: Indocyanine green (ICG) near-infrared fluorescence cholangiography (NIRF-C) is widely used to visualize the biliary tract during laparoscopic cholecystectomy (LC). However, the ICG dose and its dosing time vary in the literature so there is not a standard ICG protocol. The objectives of this descriptive prospective study were to demonstrate that NIRF-C at a very low dose of ICG provides good visualization of the extrahepatic biliary tree while avoiding hepatic hyperluminescence and to assess the surgeon-perceived benefit.

Cephalic pancreaticoduodenectomy for ductal adenocarcinoma in the elderly. Can we do it safely?

Introduction: Surgery and chemotherapy have increased the survival of pancreatic cancer. The decrease in postoperative morbidity and mortality and increase in life expectancy, has expanded the indications por cephalic pancreaticoduodenectomy (PDC), although it remains controversial in the geriatric population.

Methods: Retrospective study on a prospective database of patients with ductal adenocarcinoma of pancreas who underwent PDC between 2007-2018.

A review of the diagnosis and management of liver hydatid cyst.

Hydatidosis is a zoonosis caused by Echinococcus in the larval stage. Humans are accidental intermediary hosts where cystic lesions develop, primarily in the liver and the lungs. It is usually asymptomatic, hence it often represents an incidental finding.

Contributions of fluorescence to endocrine surgery.

The use of fluorescence in surgery has expanded and become widespread in recent years, which has led to a real technological phenomenon with the emergence of devices adapted for use in laparoscopic and robotic approaches. Fluorescence-guided surgery in the field of endocrine surgery is also on the rise. More and more articles describe its use in surgery of the thyroid, parathyroid and adrenal glands, although the series are still modest in size and protocols have not been standardized.

Laparoscopic transgastric endoscopic retrograde cholangiopancreatography after biliopancreatic diversion.

Endoscopic retrograde cholangiopancreatography may be difficult in patients that have undergone Roux-en-Y gastric bypass. Due to the fact that prevalence of morbid obesity is increasing, and laparoscopic procedures for its treatment have increased, the incidence of biliary tract problems in patients of altered anatomy is also growing. We describe a laparoscopic technique to access the biliary tree by endoscope, through the excluded stomach.
