Extraskeletal osteosarcoma is a rare and invasive malignancy, typically located in the soft tissue without attachment to the skeleton. The present study reports a case of a primary mesenteric extraskeletal osteosarcoma of a 71-year-old woman. The patient complained of an incomplete defecation. Colonoscopy showed an ulcer with impression of external compression of the sigmoid. An additional abdominal computed tomography (CT) scan revealed a large, almost completely calcified, mass in the left lower abdomen causing hydronephrosis of the left kidney...

AIM: To identify the factors influencing cecal insertion time (CIT) and to evaluate the effect of obesity indices on CIT. METHODS: We retrospectively reviewed the data for participants who received both colonoscopy and abdominal computed tomography (CT) from February 2008 to May 2008 as part of a comprehensive health screening program. Age, gender, obesity indices [body mass index (BMI), waist-to-hip circumference ratio (WHR), waist circumference (WC), visceral adipose tissue (VAT) volume and subcutaneous adipose tissue (SAT) volume on abdominal CT], history of prior abdominal surgery, constipation, experience of the colonoscopist, quality of bowel preparation, diverticulosis and time required to reach the cecum were analyzed...

INTRODUCTION: Multiple primary neoplasms are relatively rare, but their incidence has increased because of aging and improvements in diagnostic imaging. PRESENTATION OF CASE: A 67-year-old man presented with epigastric pain. On upper gastrointestinal endoscopy, an ulcer was seen at the gastric angle, and biopsy showed moderately differentiated adenocarcinoma (AC). Colonoscopy demonstrated a 15-mm lesion in the sigmoid colon and a submucosal lesion in the lower rectum...

BACKGROUND: Colon ischemia (CI), is generally considered a non-occlusive mesenteric ischemia disorder that usually runs a benign course, but right-sided involvement (RCI) has been associated with worse outcome. The poor outcome of RCI has been associated with comorbidity, but more recently also with occlusions of the mesenteric arteries. We performed a retrospective analysis of a large cohort of CI-patients to assess differences in presentation, etiology, and comorbidity between right-sided colon ischemia (RCI) and non-right-sided colon ischemia (NRCI), and their relation to outcome...

INTRODUCTION: There is no consensus on the relationship between patient sex and the location, stage and oncologic outcome of colon cancer (CC). We hypothesized a sex-specific difference in the biology and management of CC. STUDY DESIGN: Our cohort was drawn from a database of patients enrolled in international trials of nodal ultrastaging for non-metastatic CC. These trials required strict adherence to surgical and pathological quality measures. Postoperative follow-up included colonoscopy at 1 and 4 years and annual CT scans...

AIM: Same day CT colonography (CTC) for incomplete colonoscopy should be considered to avoid the need for further bowel preparation. Oral administration of contrast is essential for optimal colonic analysis of the CTC. Our aim was to determine the optimal time for giving contrast to people who underwent same day CTC after failed colonoscopy. METHODS: Data was extracted from the Trust database to identify the number of CTC referrals following failed or incomplete colonoscopy within the last 5 years, and the reason for their referral...

A 60-year-old woman visited our hospital due to hematochezia. Colonoscopy revealed a 50-mm-diameter submucosal tumor with ulceration of the left side of the transverse colon, and magnetic resonance imaging (MRI) demonstrated the presence of small hepatic nodules. Submucosal tumor of the colon with liver metastasis was therefore diagnosed. To prevent tumor bleeding, we performed partial transverse colectomy. The histopathological diagnosis was moderately differentiated hepatocellular carcinoma presenting as a submucosal tumor with a high frequency of vascular invasion...

CT colonography is a CT examination focused on the detection of colonic polyps and masses. Its most common indications include incomplete optical colonoscopy and generally personal preference in symptomatic or frail patients. CT colonography has a diagnostic yield similar to optical colonoscopy. It is less demanding for the patient, has shorter examination times, lower rates of adverse effects (including bowel perforation) and allows limited evaluation of extracolonic structures. In 10-15 % of asymptomatic patients, optical colonoscopy is needed if either a colonic polyp or mass is detected...

Colitis can be a life-threatening toxicity for patients treated with immune checkpoint blockade antibodies. With the anticipated widespread use of these reagents, the timely and accurate diagnosis of immune-related colitis becomes increasingly important. To better understand the clinical presentation of colitis from ipilimumab and to assess the use of CT scans of the abdomen/pelvis as a diagnostic tool, we retrospectively analyzed patients with advanced melanoma who received ipilimumab at our institution. Ninety nine (33%) of 303 patients developed diarrhea during therapy, and 46 patients (15%) received corticosteroids for colitis...

INTRODUCTION: Leiomyosarcoma of the gastrointestinal tract is very rare, with a reported frequency of less than 0.1% of all malignancies of the colorectum. It is important to diagnose leiomyosarcoma definitively by immunohistochemical profiling of smooth muscle actin, desmin, and CD34. True leiomyosarcoma of the colorectum diagnosed by immunnohistochemical profiling is extremely rare that only 13 reports have been published in reviews of resected gastrointestinal mesenchymal tumors after 1998...

Migration of percutaneous endoscopic gastrostomy (PEG) tube to colon with gastro-colonic-cutaneous fistula formation is a rare complication of the procedure. Transient episodic diarrhea following each PEG tube feeding is typical of this complication. We present a 72-year-old man with cerebrovascular disease and scoliosis who encountered episodes of transient diarrhea after each PEG tube feeding. His diarrhea was refractory to medications. Colonoscopy demonstrated a mal-positioned PEG in the transverse colon...

BACKGROUND: Sacrococcygeal pilonidal disease is a chronic, well-recognized entity, characterized by the recurrent formation of an abscess or draining sinus over the sacrococcygeal area. It is one of the most common surgical problems. Rarely, chronic inflammation and recurrent disease leads to malignant transformation, most commonly to squamous cell carcinoma (SCC). CASE PRESENTATION: We describe an extremely unusual case of SCC developing in a 60-year-old patient with a chronic pilonidal sinus complicated by an anal fistula...

OBJECTIVE: To evaluate the diagnostic accuracy of a single CEA (carcinoembryonic antigen) blood test in detecting colorectal cancer recurrence. BACKGROUND: Patients who have undergone curative resection for primary colorectal cancer are typically followed up with scheduled CEA testing for 5 years. Decisions to investigate further (usually by CT imaging) are based on single test results, reflecting international guidelines. METHODS: A secondary analysis was undertaken of data from the FACS trial (two arms included CEA testing)...

A 58-year-old man was admitted due to a 4-month history of colicky right upper quadrant pain, intermittent fever, anorexia and weight loss. A contrast-enhanced CT scan of the abdomen showed an encapsulated, peripherally enhancing focus occupying the right liver lobe exhibiting capsular rupture and extension to the walls of the hepatic flexure. He immediately underwent emergency ultrasound-guided percutaneous catheter drainage and cultures of the purulent fluid later revealed Escherichia coli A colonoscopy was then performed which showed a pinpoint opening with draining pus at the hepatic flexure...

Sclerosing mesenteritis (SM) is an extremely rare disease characterized by chronic non-specific inflammation, fat necrosis and fibrosis of the mesentery. We presented a 77-year-old man with progressive dyschezia, abdominal pain and mass in left lower quadrant. Computed tomography (CT) exhibited a thickened mesentery, enlarged lymph nodes and strand-like densities around the mesenteric vessels. However, laboratory investigation, colonoscopy and positron emission tomography did not provide any specific results for diagnosis...

OBJECTIVE: There is controversy whether constipation as a primary presenting complaint is an indication for diagnostic colonoscopy. CT colonography (CTC) is a less invasive and more acceptable alternative. We compared the completion and sensitivity of colonoscopy with CTC in patients who presented with the primary symptom of constipation. METHODS: A retrospective study was conducted which examined the first 100 colonoscopies and 100 CTCs carried out for the primary symptom of constipation from June 2012 to December 2013...

BACKGROUND: Cardiac metastasis from colorectal cancer is rare. There is little evidence supporting the effectiveness of chemotherapy, and standard therapy for metastatic cardiac tumors has not been established. CASE PRESENTATION: A 76-year-old woman presented with a right ventricle tumor that was detected incidentally on screening cardiac ultrasonography. The initial computed tomography (CT) scan showed the cardiac tumor, which was approximately 40 mm in size, and multiple pulmonary nodules...

BACKGROUND: In the past diverticulitis was believed to be uncommon in the young population. However, there is growing concern suggesting that these patients develop more severe clinical symptoms and may require more frequent intervention. METHOD: We performed a retrospective chart review of patients with diverticulitis in individuals with age less than 40 years over an 8 year period (2007-2015). Diagnosis was confirmed with a CT scan. In addition to age we took into consideration race, gender, anemia (hematocrit< 41), leukocytosis (WBC > 12), BMI and whether it was an initial episode or recurrence...

Low-grade appendiceal mucinous neoplasms (LAMNs) are neoplastic lesions with potential progression to pseudomyxoma peritonei (PMP). In most cases, diagnosis is made because of suspected acute appendicitis or incidentally by computed tomography (CT). However, incidental diagnosis during colonoscopy is rare. We present the case of a 63-year-old man with a LAMN type 1 lesion, diagnosed at routine colonoscopy for surveillance of ulcerative colitis. Because in earlier surveillance colonoscopies, this lesion was misinterpreted as fecal polution, for the first time, this case describes retrospectively a 3-year endoscopic follow-up of LAMN type 1, underlining the benign course of these kind of lesions compared to type 2 lesions with submucosal infiltration...

INTRODUCTION: Pseudomyxoma peritonei (PMP) is a rare condition caused by mucinous adenocarcinoma cancerous cells that produce abundance of mucin or gelatinous ascites. This cancer can cause tissue fibrosis and can impair normal organ function. Diagnosis can involve multiple imaging modalities including CT scan. There have been few cases of endoscopic ultrasound (EUS) being used as a means for diagnosis of this condition. Here we report a second case of PMP with a previous history of appendectomy diagnosed with EUS guided fine needle aspiration (FNA) biopsy...
