This article will discuss the dietary, bowel preparation, and fecal/fluid tagging options to best prepare the colon. Strategies to optimally distend the colon will also be discussed. CT scan techniques including patient positioning and radiation dose optimization will be reviewed. With proper technique which includes sufficient bowel preparation, fecal/fluid tagging, bowel distension, and optimized scan technique, high-quality CTC examinations should become more feasible, easier to interpret, and more consistently reproducible leading to increased utilization and increased referrals.

Question: A 60-year-old man complaining of recurrent melena for> 2 months, accompanied by fatigue and anemia, was admitted to our gastroenterology ward. He denied experiencing hematemesis, abdominal pain, fever, osteodynia, or arthralgia. His medical history included a 6-year history of alcoholic hepatocirrhosis and type 2 diabetes mellitus. Colonoscopy found no evidence of hemorrhage. However, gastroduodenoscopy showed multiple polypoid lesions in the duodenum (Figure A, B). An abdominal computed tomography (CT) scan was performed (Figure C).

CONCLUSION: While New Zealand outcomes in colorectal cancer have historically compared unfavourably against international standards, the outcomes observed in this cohort are encouraging and may reflect advances in care, including multidisciplinary team discussion, increased use of adjuvant therapy, surgical subspecialisation and protocolled surveillance and follow-up.

We report a case of 55-year-old female who presented with a sudden onset of sharp right lower quadrant abdominal pain. Electronic colonoscopy showed a normal lumen. However, an abdominal computed tomography scan revealed a mass of soft tissue attenuation inseparable from the ascending colon which appeared as a gastrointestinal stromal tumor (GIST).Diagnoses:It is important to diagnose LMS definitively by immunohistochemical profiling of smooth muscle actin, desmin, and CD34.Interventions:She underwent laparotomy and right hemicolectomy, and histology confirmed a colonic LMS. The patient received no oncological treatment af...

This report presents a case of sigmoid colon translocation of intrauterine device on a 37-year-old female patient. Colonoscopy was performed due to her complain of repeated blood in stools and subsequently the patient was misdiagnosed as a sigmoid colon polyp. Nonetheless, the “polyp” was not able to be removed endoscopically.Diagnoses:Sigmoid colon translocation of an intrauterine device.Interventions:To further clarify the diagnosis, computed tomography (CT) scan was performed and the “polyp” was confirmed to be caused by a translocated IUD.Outcomes:The translocated IUD was removed easily by surge...

Abstract An 81-year-old patient with significant cardiac comorbidities, a history of sigmoid resection 6 years ago, and iliac bypass surgery 19 years ago presented with mild hematochezia for the previous 3 days. While hemodynamically stable at first, he developed massive bleeding during preparation for colonoscopy and underwent a short course of cardiopulmonary resuscitation. Colonoscopy revealed no active bleeding but a protuberance of the colonic wall and a coagulation clot. In ultrasonography immediately after endoscopy, a large aneurysm was diagnosed and diagnosis of an iliaco-colonic fistula was assumed. CT s...

Conclusions:The strength of agreement among imaging, endoscopic, and histologic findings was suboptimal. Colonoscopy and imaging are both likely to be necessary in patients with suspected inflammatory bowel disease. Although colonoscopy may be superior in diagnosis of colitis, imaging may provide more information regarding small bowel disease. Background: Computed tomography scans (CTs), more recently magnetic resonance imaging, are often used to assess the gastrointestinal tract in patients complaining of abdominal pain. We aim to determine the strength of agreement among abdominal imaging, endoscopic, and histologic ...

We present a case of a diverticulum of the sigmoid colon with intense prostate-specific membrane antigen (PSMA) activity on 68Ga-PSMA PET/CT. CT scan and colonoscopy showed no signs of inflammation or malignancy. This case presents an addition to the collection of benign pitfalls when reporting PSMA PET/CT; however, a 68Ga-PSMA up-taking focus in the colon should always cause further examination, as malignant etiology must be ruled out.

We report the case of a 66-year-old man with fecal occult blood. In the case, sudden epigastric pain after colonoscopy owing to diaphragmatic hernia in a left hemidiaphragm.Diagnoses:The diagnoses made by a CT scan without delay. It showed marked protrusion of the large bowel into the left thoracic cavity along with elevation of the left diaphragm.Interventions:The diaphragmatic defect was repaired by simple closure and intestinal adhesions release surgery.Outcomes:Five days after surgery, the patient was discharged in good condition.Lessons:Most of diaphragmatic hernia is congenital with high mortality. However, there are...

By MARGALIT GUR-ARIE A few weeks ago one man, named @jack, decided that millions of people will be allowed to use up to 280 characters when expressing themselves on Jack’s public square platform. One man decides how many letters each and every one of us, including the “leader of the free world”, can use when we talk to each other. Just like that. Nobody seemed the least bit perturbed by this notion. Another dude, named Mark, decided to ask people for nude pictures of themselves, so he can better protect them from the bad guys. We shrugged that off too. Then, in a most embarrassing exercise in public humil...
