INTRODUCTION: Low anterior resection (LAR) with total mesorectal excision (TME) represents the gold standard for patients with low rectal carcinoma. Protective ileostomy (PI) is commonly performed during LAR in an effort to protect low rectal anastomosis. The aim of this study is to analyse outcomes in our own patient population, focusing on morbidity associated with PI. METHOD: A retrospective clinical study of patients operated on between 2013 and 2015 was conducted in University Hospital Ostrava...

HuR is an RNA-binding protein implicated in immune homeostasis and various cancers, including colorectal cancer. HuR binding to AU-rich elements within the 3' untranslated region of mRNAs encoding oncogenes, growth factors, and various cytokines leads message stability and translation. In this study, we evaluated HuR as a small-molecule target for preventing colorectal cancer in high-risk groups such as those with familial adenomatosis polyposis (FAP) or inflammatory bowel disease (IBD). In human specimens, levels of cytoplasmic HuR were increased in colonic epithelial cells from patients with IBD, IBD-cancer, FAP-adenoma, and colorectal cancer, but not in patients with IBD-dysplasia...

Small bowel adenocarcinoma (SBA) complicating Crohn's disease (CD) is rare and generally found incidentally on surgical specimens. We report our experience in CD-associated SBA observed this last decade in a tertiary referral centre in order to update its incidence, clinical presentation and pathological features. All SBAs diagnosed in patients who underwent surgery for CD between 2006 and 2016 were retrospectively included. Clinico-pathological characteristics were reviewed, and follow-up was updated. SBA was diagnosed in 9 (1...

BACKGROUND: Although benefits of laparoscopic surgery compared with open surgery have been suggested, the long-term survival of patients undergoing laparoscopic surgery for colon cancer requiring Japanese D3 dissection remains unclear. We did a randomised controlled trial to establish non-inferiority of laparoscopic surgery to open surgery. METHODS: We did an open-label, multi-institutional, randomised, two-arm phase 3 trial in 30 hospitals in Japan. Patients aged 20-75 years who had histologically proven colon cancer; tumours located in the caecum or ascending, sigmoid, or rectosigmoid colon; T3 or deeper lesions without involvement of other organs, node stages N0-2, and metastasis stage M0; and tumour size of 8 cm or smaller were included...

Guanylate cyclase C (GUCY2C) is a tumor suppressing receptor silenced by loss of expression of its luminocrine hormones guanylin and uroguanylin early in colorectal carcinogenesis. This observation suggests oral replacement with a GUCY2C agonist may be an effective targeted chemoprevention agent. Linaclotide is an FDA approved oral GUCY2C agonist formulated for gastric release, inducing fluid secretion into the small bowel to treat chronic idiopathic constipation. The ability of oral linaclotide to induce a pharmacodynamic response in epithelial cells of the colorectum in humans remains undefined...

BACKGROUND: Irreversible electroporation (IRE), a nonthermal injury ablation technique, has been shown to be effective and safe in various organs, such as in the kidney, liver, prostate, or in pancreas. In contrast to radiofrequency or microwave ablation, IRE is also effective in the neighborhood of major vessels. Many human cancers reveal lymphatic spread. The present study aimed to evaluate technical feasibility and safety of IRE in lymphatic tissue. To our knowledge, this is the first report showing successful IRE of lymph nodes in a standardized porcine survival model...

CONTEXT/OBJECTIVE: Colonoscopy with polypectomy is associated with a reduced risk of colorectal cancer (CRC), but poor bowel cleansing limits the diagnostic yield of the procedure. Patients with spinal cord injury (SCI) frequently have suboptimal bowel cleansing with standard pre-colonoscopy bowel preparation regimens. We aimed to assess the safety, tolerability, and efficacy of a multi-day inpatient bowel preparation regimen in a population of patients with SCI. DESIGN: Retrospective case series...

Autoimmune pancreatitis (AIP) is a chronic fibroinflammatory disease of the pancreas that belongs to the spectrum of immunoglobulin G-subclass4-related diseases (IgG4-RD) and typically presents with obstructive jaundice. Idiopathic duct-centric pancreatitis (IDCP) is a closely related but distinct disease that mimics AIP radiologically but manifests clinically most commonly as recurrent acute pancreatitis in young individuals with concurrent inflammatory bowel disease. IgG4 levels are often elevated in AIP and normal in IDCP...

OBJECTIVE: Chemotherapy for cancer is a systemic treatment often associated with side effects than can be debilitating and, in some cases, life-threatening. Few data are available on intestinal enterotoxicity. Wireless video capsule endoscopy (VCE) is a noninvasive method of imaging the small intestine. This study presents the results of VCE in patients with solid tumors undergoing antineoplastic regimens with agents, notably for toxicity for the gastrointestinal mucosa (i.e. carboplatin, cyclophosphamide, 5-fluorouracil, methotrexate, and cisplatin)...

Giardia lamblia (G. lamblia)-filled pancreatic masses are a rarely reported entity. Furthermore, there are only a few case reports in literature on the association of these masses with cancer. We present a case of a G. lamblia-filled pancreatic cystic mass in a patient with a history of T-cell-rich B-cell lymphoma. The authors performed a PubMed search using (Medical Subject Headings) MeSH terms of pancreas, mass, Giardia, and lymphoma.  A 53-year-old male with past medical and surgical history of T-cell-rich B-cell lymphoma, status post R-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab) therapy with positron emission tomography (PET) scan showing no residual disease, essential hypertension, and alcohol use disorder presented to the emergency department (ED) with epigastric pain and nausea for one week...

A 21-year-old woman with Peuts-Jeghers syndrome (PJS) was referred to our hospital for gastrointestinal surveillance. She had been diagnosed as having PJS from a young age based on her family history and the presence of mucocutaneous pigmentation on her lips and oral mucosa. Her mother and brother had PJS harboring an entire deletion of the STK11 gene. She had tetralogy of Fallot, atrial tachycardia, sick sinus syndrome, and mental retardation in her past history. Esophagogastroduodenoscopy identified a protruded lesion with a depressed area that occupied the lumen half-circumferentially in the duodenal second portion and also showed a 10-mm protruded lesion on the anterior wall of the lower gastric body...

Nanoparticle (NP) therapeutics can improve the therapeutic index of chemoradiotherapy (CRT). However, the effect of NP physical properties, such particle size, on CRT is unknown. To address this, we examined the effects of NP size on biodistribution, efficacy and toxicity in CRT. PEG-PLGA NPs (50, 100, 150nm mean diameters) encapsulating wotrmannin (wtmn) or KU50019 were formulated. These NP formulations were potent radiosensitizers in vitro in HT29, SW480, and lovo rectal cancer lines. In vivo, the smallest particles avoided hepatic and splenic accumulation while more homogeneously penetrating tumor xenografts than larger particles...
