Serrated polyps are a recently recognized family of colonic polyps with subgroups that harbor future malignant potential. In the past, the significance of these lesions to the colorectal cancer carcinogenesis pathway was not recognized nor well understood. It is now known that serrated polyps account for approximately one-fourth of all sporadic colorectal cancers. The sessile serrated polyp (SSP) (also known as a sessile serrated adenoma [SSA]) is the main lesion of interest given its prevalence and subtle presentation...

RATIONALE: Colonoscopy is a relatively safe and common procedure with low risks of complications, and acute appendicitis with perforation is an extremely rare complication of colonoscopy. The current study presents an unusual case of acute gangrenous appendicitis with perforation following a screening colonoscopy. PATIENT CONCERNS: A 73-year-old man presented to our emergency department with lower right abdominal pain 3 days after a routine screening colonoscopy...

About 10% of oesophagogastroduodenoscopies (OGDs) and colonoscopies are done for investigation of iron deficiency anemia (IDA) . Much of the existing guidance on investigation of IDA predates CRC screening, which has driven significant improvements in colonoscopy quality and completion rates, as well as a reduction in Helicobacter pylori prevalence and increase in PPI usage, and therefore probably needs re-consideration. New investigations, e.g. CT colonography, enteroscopy and capsule endoscopy have also been introduced...

Background and study aims:  Urgent endoscopy is often used to diagnose and sometimes treat acute upper gastrointestinal syndromes (hemorrhage, toxic ingestion, and occlusion). However, its suitability concerning the management of lower gastrointestinal conditions in emergency circumstances is controversial. Patients and methods:  We studied the role of emergency colonoscopy in diagnosis and treatment of all consecutive patients presenting with acute lower gastrointestinal symptoms referred to our hospital on an emergency basis...

Most medical professionals consider colonoscopy to be a safe procedure with a low rate of severe complications such as bowel perforation, gastrointestinal tract bleeding, or mortality. Bowel wall hematoma is a rare complication associated with colonoscopy that can result in significant morbidity and even mortality. We present a case of postpolypectomy hematoma diagnosed with CT imaging and successfully managed in a conservative fashion.

BACKGROUND While it is well known that abdominal wall hernias can pose obstacles for colonoscopy, these may not be obvious in obese patients, particularly when the hernia is in an unusual place. CASE REPORT A 62-year-old man presented with inability to complete colon cancer screening by means of colonoscopy or barium enema. On exam, he was noted to have a Spigelian hernia present in his left lower quadrant abdominal wall. CT colonography identified incarcerated sigmoid colon within the hernia accounting for his inability to complete colonoscopy or barium enema...

A 60-year-old female presented to our hospital with anal pain. Colonoscopy (CS) revealed a tumor in the anal canal, which was diagnosed as squamous cell carcinoma by biopsy. Computed tomography (CT) showed multiple liver metastases. From these findings, we diagnosed the anal tumor as stage IV squamous cell carcinoma of the anal canal. Although CS and CT indicated disappearance of the primary tumor and liver metastases following chemoradiotherapy, brain metastasis developed during the disease course and was treated with radiotherapy and surgical resection...

REVIEW
Etienne Joosten
Anemia in older adults is a risk factor for numerous negative outcomes. There is no standard definition, but in most studies, anemia is defined as a hemoglobin value <12 g/dL for women and <13 g/dL for men. Absolute iron deficiency anemia is defined as the combination of anemia and the absence of total body iron. Serum ferritin is the most frequently used diagnostic parameter, but its concentration increases with age and in the presence of inflammatory diseases. Other laboratory tests, such as transferrin saturation, soluble transferrin receptor and the soluble transferrin receptor/ferritin index might provide useful information, but there is a wide variety in the cut-off values and interpretation of the results...

Chronic diarrhoea is a common condition, resulting from a number of different disorders. Bile acid diarrhoea, occurring in about a third of these patients, is often undiagnosed. We hypothesised that a positive diagnosis of bile acid diarrhoea would reduce the need for subsequent investigations for alternative diagnoses. METHODS: Patients previously recruited to a study of chronic diarrhoea who had selenium homocholic acid taurine (SeHCAT) testing and subsequent follow-up at our institution were identified...

We report 2 unusual cases of Stage IV rectal cancer for which pathological complete response was achieved with neoadjuvant chemotherapy(NAC)consisting of a combination of 5-fluorouracil(5-FU), oxaliplatin, Leucovorin(mFOLFOX6)or irinotecan(FOLFIRI), and bevacizumab, without radiotherapy. Case 1: A 65-year-old man was diagnosed as having rectal cancer with an invasive carcinoma of the prostate and lymph node metastasis. He refused to undergo surgery and received NAC instead. After NAC with mFOLFOX6 and FOLFIRI was performed, CT scan and colonoscopy revealed no evidence of disease...

We report a case of appendiceal mucinous cystadenoma that was successfully diagnosed preoperatively and treated by laparoscopic resection. We could find volcano sign on colonoscopy and cystic lesion without any nodules at the appendix on computed tomography (CT). Without any malignant factors in preoperative examinations, we performed laparoscopic appendectomy including the cecal wall. We could avoid performing excessive operation for cystadenoma with accurate preoperative diagnosis and intraoperative finding and pathological diagnosis during surgery...

A 63-year-old woman underwent thyroidectomy for papillary thyroid adenocarcinoma and cervical lymph node resection. Pathological analyses revealed the presence of signet cell carcinoma in a resected lymph node, which were apparently different from the pathological findings of thyroid carcinoma. No evidence of a primary tumor could be found elsewhere despite detailed examinations, including esophagogastroduodenoscopy, colonoscopy, capsule endoscopy, CT scan, and fluorodeoxyglucose-positron emission tomography...

A 70-year-old woman with a 15-year history of coeliac disease was admitted for treatment and investigation of symptomatic anaemia. Of note, she was recently commenced on aspirin therapy for retinal artery occlusion. This followed a normal gastro-duodenoscopy, colonoscopy and CT abdomen as workup for iron deficiency anaemia. On this occasion, the patient was further investigated with small bowel capsule endoscopy. This revealed an ulcerated lesion in her proximal jejunum suspicious for malignancy, namely lymphoma...

Non-Hodgkin lymphoma often involves the liver. However, primary hepatic lymphoma (PHL) confined to the liver without evidence of lymphomatous involvement is rare. The optimal therapy for PHL is still unclear. Most patients present with poor prognostic features. Here, we report a case of PHL treated with liver resection followed by chemotherapy. A 65-year-old male was referred for further evaluation about a liver mass detected on ultrasound. Abdominal computed tomography (CT) scan showed well-defined single mass of 6 cm in diameter...

BACKGROUND: Adequate preoperative segmental localization of colorectal cancer is important to indicate the right surgical treatment. Preoperative localization has become more important in the era of minimally invasive surgery. The aim of this study was to compare optical colonoscopy (OC) and CT colonography (CTC) with respect to the error rates in the segmental localization of colorectal carcinoma. METHODS: A total of 420 patients with histopathologically proven colorectal carcinoma underwent CTC between December 2006 and February 2017...

BACKGROUND: Increased use of PET/CT scans in oncology patients has raised detection of Colorectal incidentalomas (CIs). The frequency and diagnostic outcomes of identifying these lesions in melanoma patients have not previously been studied. This studies primary objective was to determine the prevalence of CIs found on PET/CT scans in melanoma patients. The secondary objectives were to correlate the PET/CT findings with the pathology found at colonoscopy, and identify which patients were referred for colonoscopy...
