Background: Many Escherichia coli strains are considered to be a component of the normal flora found in the human and animal intestinal tracts. While most E. coli strains are commensal, some strains encode virulence factors that enable the bacteria to cause intestinal and extra-intestinal clinically-relevant infections. Colibactin, encoded by a genomic island (pks island), and cytotoxic necrotizing factor (CNF), encoded by the cnf gene, are genotoxic and can modulate cellular differentiation, apoptosis and proliferation...

BACKGROUND: Several histological high-risk factors are used as an indication for adjuvant therapy in stage II colon cancer. Those and other factors, including lymphatic invasion, perineural invasion (PNI), venous invasion and tumour budding are associated with decreased outcome. In this study, we evaluated the prognostic and predictive values of these biomarkers in a cohort of rectal cancer patients. MATERIALS AND METHODS: The trial-based cohort consisted of 221npTNM stage II-III rectal cancer patients, included in the PROCTOR/SCRIPT trial, a multicentre randomised phase III trial...

BACKGROUND AND OBJECTIVES: Management of postoperative pain after laparoscopic segmental colonic resections remains controversial. We compared 2 methods of analgesia within an Enhanced Recovery After Surgery (ERAS) program. The goal of the study was to investigate whether administration of intrathecal bupivacaine/morphine would lead to an enhanced recovery. METHODS: A single-center, randomized, double-blind controlled trial was performed (NL43488.101.13). Patients scheduled for laparoscopic segmental intestinal resections were considered...

INTRODUCTION: Surgical repair of rectovaginal fistula remains a challenge. Complex and recurrent rectovaginal fistula repairs often fail because of scarring and devascularization of the surrounding tissue. Omental interposition may promote healing by introducing bulky vascularized tissue into the rectovaginal septum. TECHNIQUE: With the patient in the lithotomy position, the rectovaginal septum was dissected transperineally up to the fistula tract and the openings on both vaginal and rectal sides were closed using interrupted, absorbable sutures...

AIM: The rectosigmoid junction is the limit separating the sigmoid colon and rectum. This transition zone has different definitions. We want to highlight different landmarks of the rectosigmoid junction (RSJ), to help the clinicians to adopt a consensual definition. METHOD: We reviewed anatomical, endoscopic, physiological and surgical points of view concerning the rectosigmoid junction (RSJ). RESULTS: The rectosigmoid junction has a different definition depending on who is studying it...

A 65-year-old female patient presented to the emergency clinic with abdominal pain, meteorism, and intermittent rectal bleeding. Colonoscopy was performed, and a hepatic flexure tumor was detected. Histopathological examination of biopsy revealed adenocarcinoma. Thoracoabdominal CT was performed for staging, and a spiculated contour mass was found incidentally on the left breast. Mammography and ultrasonography were performed for the cause of these findings, and suspicious lesions of malignancy were seen in the left breast...

Colorectal carcinoma (CRC) is the third most commonly diagnosed cancer and the third leading cause of cancer death in both men and women in the US. It is mainly a disease of the developed countries with a western culture, yet the disease is not uncommon in developing countries. There is substantial geographical variation in the incidence and demographic characteristics of the disease. Variations are also observed in the risk factors, mode of presentation, sub site distribution and stage of the disease at presentation...

The incidence of rectal neuroendocrine tumors (NETs) has increased by almost ten-fold over the past 30 years. There has been a heightened awareness of the malignant potential of rectal NETs. Fortunately, many rectal NETs are discovered at earlier stages due to colon cancer screening programs. Endoscopic ultrasound is useful in assessing both residual tumor burden after retrospective diagnosis and tumor characteristics to help guide subsequent management. Current guidelines suggest endoscopic resection of rectal NETs ≤10 mm as a safe therapeutic option given their low risk of metastasis...

Hartmann's procedure, colonic resection with an end colostomy and rectal closure, is used in a variety of surgical emergencies. It is a common surgical procedure that is often practiced in patients with colonic obstruction and colonic perforation, resolving the acute clinical situation in the majority of cases. Reversal of Hartmann's procedure with restoration of bowel continuity occurs in a significantly low percentage of patients. There are several reasons contributing to the fact that many patients remain with a permanent colostomy following Hartmann's procedure...

Background & Aims: Three-dimensional organoid culture has fundamentally changed the in vitro study of intestinal biology enabling novel assays; however, its use is limited because of an inaccessible luminal compartment and challenges to data gathering in a three-dimensional hydrogel matrix. Long-lived, self-renewing 2-dimensional (2-D) tissue cultured from primary colon cells has not been accomplished. Methods: The surface matrix and chemical factors that sustain 2-D mouse colonic and human rectal epithelial cell monolayers with cell repertoires comparable to that in vivo were identified...
