Impact of indocyanine green on decision making for performing laparoscopic cortical sparing adrenalectomy.

Background: Indocyanine green imaging (ICG) is an expansion technology that can contribute to the development of demanding techniques such as cortical-sparing adrenalectomy (CSA). The aim of this study was to determine in which cases CSA should be performed and when total adrenalectomy should be performed instead based on ICG fluorescence. Here, we present our experience through a series of cases and videos.

Prevertebral cervical approach to posterior mediastinum parathyroid adenomas.

Background: About 4 years ago, we described the pure endoscopic cervical approach to posterior mediastinum parathyroid adenomas, which we called the "prevertebral cervical approach". At that time, we had operated on three patients and did not have enough quality videos to demonstrate this approach. After broadening our experience, we present our results and show this technique through a video.

Translational pancreatic cancer research: A comparative study on patient-derived xenograft models.

Aim: To assess the viability of orthotopic and heterotopic patient-derived pancreatic cancer xenografts implanted into nude mice.

Methods: This study presents a prospective experimental analytical follow-up of the development of tumours in mice upon implantation of human pancreatic adenocarcinoma samples. Specimens were obtained surgically from patients with a pathological diagnosis of pancreatic adenocarcinoma.

Post-transplant lymphoproliferative disease in liver transplant recipients.

Introduction: Post-transplant lymphoproliferative syndrome (PTLD) is a rare and potentially life-threatening complication after liver transplantation. The aim of this study was to analyze the clinicopathologic features related to PTLD in a single institution after liver transplantation.

Methods: Observational study where we have retrospectively analyzed 851 cases who underwent liver transplantation.

Implication of the presence of a variant hepatic artery during the Whipple procedure.

Introduction: The anatomical variants of the hepatic artery may have important implications for pancreatic cancer surgery. The aim of our study is to compare the outcome following a pancreatoduodenectomy (PD) in patients with or without a variant hepatic artery arising from superior mesenteric artery.

Material And Methods: We reviewed 151 patients with periampullary tumoral pathology.

The role of tridimensional dynamic ultrasound for pelvic floor evaluation.

Introduction: Dynamic endoanal ultrasound has emerged in recent years as a test that could replace the now existing tests in the diagnosis of pelvic floor disorders. The aim of this paper is to determine the usefulness of echodefecography in the diagnosis and evaluation of patients with symptoms of anorrectal obstruction, and show the results obtained after its implementation in a pelvic floor unit, as a complementary tool that could replace conventional defecography.

Methods: In this retrospective study we analyzed 66 patients with a mean age of 55 years (19-83), 61 women (92%).

Single-port Roux-en-Y gastric bypass: toward a less invasive procedure with the same surgical results and a better cosmesis.

Background: The current tendency to use increasingly less aggressive procedures has facilitated the development of new minimally invasive techniques. In this context, single-port (SP) access procedures can become an alternative to the conventional laparoscopic approach.

Methods: A total of 22 morbidly obese patients were submitted to pure SP Roux-en-Y gastric bypass without additional ports.
