Ureteral identification with indocyanine green in laparoscopic colorectal surgery.

Introduction: Fluorescence-guided surgery has emerged as a complement of traditional laparoscopic surgery with the advantage that is adaptable to existent platforms. The purpose of this article is to describe our technique for ureteral identification with indocyanine green (ICG) during laparoscopic colorectal surgery.

Materials And Surgical Technique: We report a case series of all patients who underwent laparoscopic colorectal surgery and ureteral injection of ICG in a private third level hospital.

Neuroendocrine tumors in Panama: A nationwide database analysis.

Neuroendocrine tumors (NETs) comprise a heterogenous group of rare malignancies, which are increasing in incidence worldwide. To further understand the epidemiology of NETs in the Republic of Panama, the present study used two study groups, which included patients from several hospitals and clinics throughout the country, who were referred to the three largest national reference centers: The Complejo Hospitalario Metropolitano, Hospital Santo Tomas and Instituto Oncologico Nacional. These two groups comprised a retrospective cohort, which included cases reported between 2016 and 2017, and a second cohort, which was retrospective, but data were continuously collected from patients diagnosed with NETs between 2018 and 2019.

Baseline characteristics, survival and direct costs associated to treatment of gastric cancer patients at the National Oncology Institute of Panama from 2012 to 2015: a hospital-based observational study.

Objectives: Comprehensive epidemiological and economic studies of gastric cancer (GC) in Panama are limited. This study aims to evaluate the association between socioeconomic and clinical variables with survival, describe the survival outcomes according to clinical stage and estimate the direct costs associated to GC care in a Panamanian population with GC.

Design And Setting: A retrospective observational study was conducted at the leading public institution for cancer treatment in Panama.

Exploring the rising incidence of neuroendocrine tumors: a population-based analysis of epidemiology, metastatic presentation, and outcomes.

Background: An increased incidence of neuroendocrine tumors (NETs) has been reported worldwide, but the reasons underlying this rise have not been identified. By assessing patterns of metastatic presentation, this study sought to examine the epidemiologic characteristics of NETs and the contribution of early-stage detection to the rising incidence.

Methods: A population-based retrospective cohort study was conducted with prospectively maintained databases linked at the Institute for Clinical Evaluative Sciences.

Hepatic parenchymal preserving technique in the management of diffuse bilateral neuroendocrine tumour liver metastases: a feasible approach.

Background: Aggressive surgical resection of neuroendocrine tumour liver metastases (NET-LM) is associated with symptomatic relief. Debulking up to 90% of tumour burden, even with positive margins, may be beneficial. However, patients with diffuse hepatic metastases may not qualify for resection owing to associated insufficient remnant liver parenchyma.

Single-stage anterior high sacrectomy for locally recurrent rectal cancer.

Study Design: A review of prospectively collected data on a consecutive series of patients undergoing single-stage anterior high sacrectomy for locally recurrent rectal carcinoma (LRRC).

Objective: To determine the clinical outcome of patients who underwent anterior high sacrectomy for LRRC.

Summary Of Background Data: High sacrectomy for oncological resection remains technically challenging.

Ki-67 is a reliable pathological grading marker for neuroendocrine tumors.

In neuroendocrine tumors (NETs), proliferation markers, especially Ki-67, have become increasingly important. This study was designed to examine the reproducibility of Ki-67 for use in the current classification of NETs. A retrospectively assembled integrated database with prospectively collected data of patients undergoing multidisciplinary management for NETs from 2000 to 2009 was analyzed.
