Colorectal Cancer Stem Cells: From the Crypt to the Clinic

2014

Since their first discovery, investigations of colorectal cancer stem cells (CSCs) have revealed some unexpected properties, including a high degree of heterogeneity and plasticity. By exploiting a combination of genetic, epigenetic, and microenvironmental factors, colorectal CSCs metastasize, resist chemotherapy, and continually adapt to a changing microenvironment, representing a formidable challenge to cancer eradication. Here, we review the current understanding of colorectal CSCs, including their origin, relationship to stem cells of the intestine, phenotypic characterization, and underlying regulatory mechanisms. We also discuss limitations to current preclinical models of colorectal …

Minimally invasive interval debulking surgery in ovarian neoplasm (MISSION trial–NCT02324595): a feasibility study

2016

Background Laparoscopy has acquired an increasing role in the management of ovarian cancer. Laparoscopic cytoreduction could represent a new frontier for selected patients after neoadjuvant chemotherapy (NACT). Objective We sought to assess feasibility and early complication rate of minimally invasive (MI) interval debulking surgery (IDS) in stage III-IV epithelial ovarian cancer (EOC) patients after NACT. Study Design This is a phase II multicentric study in advanced EOC cases with clinical complete response after NACT, according to Gynecologic Cancer Intergroup and Response Evaluation Criteria In Solid Tumors criteria. Institutional review board approval was obtained and all patients sign…

Variant Arterial Supply of the Descending Colon by the Coeliac Trunk: A Case Report

2021

Background and Objectives: Knowledge of arterial variations of the intestines is of great importance in visceral surgery and interventional radiology. Materials and Methods: An unusual variation in the blood supply of the descending colon was observed in a Caucasian female body donor. Results: In this case, the left colic artery that regularly derives from the inferior mesenteric artery supplying the descending colon was instead a branch of the common hepatic artery. Conclusions: Here, we describe the very rare case of an aberrant left colic artery arising from the common hepatic artery in a dissection study.

Subclinical gut inflammation in ankylosing spondylitis

2015

Purpose of review Subclinical gut inflammation has been described in a significant proportion of patients with ankylosing spondylitis (AS), up to 10% of them developing it during the time of clinically overt inflammatory bowel disease. Histologic, immunologic, and intestinal microbiota alterations characterize the AS gut. Recent findings Microbial dysbiosis as well as alterations of innate immune responses have been demonstrated in the gut of AS. Furthermore, a growing body of evidence suggests that the gut of AS patients may be actively involved in the pathogenesis of AS through the production of proinflammatory cytokines, such as IL-23p19, and the differentiation of potentially pathogenic…

Safety of hospital discharge before return of bowel function after elective colorectal surgery

2020

Ileus is common after colorectal surgery and is associated with an increased risk of postoperative complications. Identifying features of normal bowel recovery and the appropriateness for hospital discharge is challenging. This study explored the safety of hospital discharge before the return of bowel function.A prospective, multicentre cohort study was undertaken across an international collaborative network. Adult patients undergoing elective colorectal resection between January and April 2018 were included. The main outcome of interest was readmission to hospital within 30 days of surgery. The impact of discharge timing according to the return of bowel function was explored using multiva…

B lymphocyte intestinal homing in inflammatory bowel disease.

2011

Abstract Background Inflammatory bowel disease (IBD) is thought to be due to an abnormal interaction between the host immune system and commensal microflora. Within the intestinal immune system, B cells produce physiologically natural antibodies but pathologically atypical anti-neutrophil antibodies (xANCAs) are frequently observed in patients with IBD. The objective is to investigate the localisation of immunoglobulin-producing cells (IPCs) in samples of inflamed intestinal tissue taken from patients with IBD, and their possible relationship with clinical features. Methods The IPCs in small intestinal, colonic and rectal biopsy specimens of patients with IBD were analysed by means of immun…

Technical characteristics can make the difference in a surgical linear stapler. Or not?

2015

Background Anastomotic leak (AL) after gastrointestinal surgery is a severe complication associated with relevant short- and long-term sequelae. Most of the anastomosis are currently performed with a surgical stapler that is required to have appropriate characteristics to guarantee good performances. The aim of our study was to evaluate, in the laboratory, pressure resistance and tensile strength of anastomosis performed with different surgical linear staplers, available in the market. Materials and methods We have been studying three linear staplers, with diverse cartridges and staple heights, of three different companies, used for gastrointestinal anastomosis and gastric or intestinal clo…
