OBJECTIVE: Computer-aided detection (CAD) systems for computed tomography colonography (CTC) can automatically detect colorectal polyps. The main problem of currently developed CAD-CTC systems is the numerous false positives (FPs) caused by the existence of complicated colon structures (e.g., haustral fold, residual fecal material, inflation tube, and ileocecal valve). This study proposes a CAD-CTC scheme using shape index, multiscale enhancement filters, and radiomic features to address the FP issue...

Intussusception is a pediatric abdominal emergency in early childhood involving telescoping of 1 part of the bowel into another part. In most children, the condition is idiopathic with no identifiable lead point. Meckel diverticulum is the most common lead point, followed by polyps and duplication cysts. We describe a case of a boy with intussusception caused by a duplication cyst that was drawn retrograde through the ileocecal valve. The patient presented after a 3-month period of symptomatology and had been considered to have constipation before signs of intestinal obstruction developed...

This report describes a two-month-old girl who presented with signs and symptoms of a distal small bowel obstruction. She underwent an abdominal ultrasound that revealed a right lower quadrant cystic mass. A Technetium-99 scan revealed increased activity in the right lower quadrant consistent with a Meckel's diverticulum. Following a nondiagnostic laparoscopic evaluation, a laparotomy was performed to allow direct palpation of the small bowel and colon. Direct palpation of the ileum revealed a soft intraluminal mass at the ileocecal valve...

BACKGROUND: Serial transverse enteroplasty facilitates weaning from parenteral support in selected patients with short bowel syndrome, although repeated procedure is frequently required. Our aim was to evaluate the outcome of a series of patients after serial transverse enteroplasty and define predictors of repeated serial transverse enteroplasty and weaning off parenteral support. METHODS: All children who underwent serial transverse enteroplasty at 4 Nordic pediatric surgery centers from 2004-2015 were included in this observational study...

Meckel's diverticulum may sometimes present as an intraluminal polypoid mass causing small bowel obstruction; however, gastrointestinal bleeding due to Meckel's diverticulum with a polypoid lesion is rare. A 14-year-old girl presented with tarry stool and syncope in our hospital. Laboratory examination showed iron-deficiency anemia with a low hemoglobin level of 5.8 g/dl. The bleeding site was detected by neither upper gastrointestinal endoscopy nor colonoscopy. Transanal double-balloon enteroscopy showed a diverticulum with an ulceration at a site approximately 50 cm from the ileocecal valve and a polypoid lesion inside of the diverticulum...

A 68-year-old man presented with progressive right lower quadrant abdominal pain and tenderness without rebound tenderness, and with constipation during the prior 9 mo. Abdomino-pelvic computed tomography and magnetic resonance imaging demonstrated a dilated appendix forming a fistula to the sigmoid colon. Open laparotomy revealed a bulky abdominal tumor involving appendix, cecum, and sigmoid, and extending up to adjacent viscera, without ascites or peritoneal implants. The abdominal mass was removed en bloc, including resection of sigmoid colon, cecum (with preservation of ileocecal valve), appendix, right vas deferens, testicular vessels, and minimal amounts of anterior abdominal wall; and shaving off of small parts of the walls of the urinary bladder and small bowel...

A 71 year-old female presented with a large, protuberant abdominal mass and was found to have both a left renal mass and a biopsy-proven neuroendocrine tumor of the ileocecal valve. Ultimately, right hemicolectomy revealed a well-differentiated and low-grade neuroendocrine tumor of the ileocecal valve, while left radical nephrectomy revealed a 23x22x15cm chromophobe renal cell carcinoma (RCC-CT) weighing 3564g. RCC-CT represents a small portion of diagnosed RCC, and generally portends a more favorable prognosis than other variants...

Metastatic tumors are rare in the breast. Well-differentiated neuroendocrine tumors (WDNETs) are slow-growing neoplasms that arise from neuroendocrine cells, particularly in the gastrointestinal tract and bronchial tree. Metastatic WDNET to the breast is a rare entity. We present a case report of ileal WDNET metastatic to the breast which was initially identified as a small mass in the patient's left breast on screening mammography. Targeted ultrasound identified a suspicious mass, and ultrasound-guided percutaneous core biopsy was performed...

Amebiasis is uncommon in developed countries. Several case reports in the literature emphasize that both the presenting symptoms and the radiological findings of colonic amebiasis closely resemble more common conditions, such as idiopathic inflammatory bowel disease and gastro-intestinal malignancy. We describe a unique case of colonic amebiasis (amebomas) coexisting with signet-ring cell carcinoma of the ileocecal valve, the cecum and the appendix. Endoscopically, the ulcerated tumor was indistinguishable from the ulcerations and pseudotumors (amebomas) detected in the ascending colon...

AIM: Glukagon-like-peptide-1 (GLP-1) and -2 (GLP-2), produced by intestinal L-cells, are key hormones regulating intestinal transit, secretion, absorption, and mucosal growth. We evaluated naïve fasting serum GLP-1 and GLP-2 levels in pediatric intestinal failure (IF). METHODS: Fifty-five IF patients with median age 4.2 (IQR 1.3-12) years and 47 matched healthy controls underwent measurement of fasting serum GLP-1 and GLP-2. RESULTS: Serum GLP-2 [19...

INTRODUCTION: Ileal duplications are encountered infrequently in adults, because symptoms including abdominal pain, intussusception, hemorrhage, and perforation usually present in early childhood. In this report, we present an adult case of ileal duplication that was revealed by double-balloon endoscopy (DBE). CASE DESCRIPTION: A 73-year-old Japanese man presented with anemia and melena. Anal DBE detected the narrow opening of an extra lumen in the ileum about 100 cm proximal to the ileocecal valve...

INTRODUCTION: This article reflects on the plight of patients with short bowel syndrome (SBS) in developing countries. SBS is life threatening, rare, complex and often not considered a priority by healthcare planners in the developing countries because of the high cost of treatment. Data was collected and analyzed from 3 different hospitals in two different countries (Romania and Austria) from November 2013 to February 2016 CASE PRESENTATION: The patient had an emergency surgery for volvulus as a result of an extensive ischemic necrosis, with just 80cm of the bowel left and no ileocecal valve after enterectomy...

REVIEW
Ji Min Lee, Kang-Moon Lee
Patients with inflammatory bowel disease have significantly increased in recent decades in Korea. Intestinal tuberculosis (ITB) and intestinal Behcet's disease (BD), which should be differentiated from Crohn's disease (CD), are more frequent in Korea than in the West. Thus, the accurate diagnosis of these inflammatory diseases is problematic in Korea and clinicians should fully understand their clinical and endoscopic characteristics. Ulcerative colitis mostly presents with rectal inflammation and continuous lesions, while CD presents with discontinuous inflammatory lesions and frequently involves the ileocecal area...

BACKGROUND: Hydrogen sulfide (H2 S) serves as a mammalian cell-derived gaseous neurotransmitter. The intestines are exposed to a second source of this gas by sulfate-reducing bacteria (SRB). Bismuth subsalicylate binds H2 S rendering it insoluble. The aim of this study was to test the hypothesis that SRB may slow intestinal transit in a bismuth-reversible fashion. METHODS: Eighty mice were randomized to five groups consisting of Live SRB, Killed SRB, SRB+Bismuth, Bismuth, and Saline...

BACKGROUND: In one anastomosis gastric bypass (OAGB), the measurement of the afferent limb starting at the angle of Treitz may result in insufficient absorptive surface of the intestine of the remaining efferent limb. To address this concern, we recently modified the technique of OAGB by constructing the gastrointestinal anastomosis at a fixed distance from the ileocecal valve (i.e., 300 cm). We adopted the new concept and named it the single anastomosis gastro-ileal bypass (SAGI). METHODS: Seven consecutive patients with morbid obesity underwent the SAGI procedure...

Although gastroduodenal ulcers are common in solid organ transplant patients, there are few reports on multiple giant ulcers in the distal ileum and ileocecal valve caused by immunosuppressants Herein, we report on a liver transplant recipient and a renal transplant recipient with multiple large ulcers in the distal ileum and ileocecal valve who rapidly achieved ulcer healing upon withdrawal of sirolimus or tacrolimus and administration of thalidomide. In case 1, a 56-year-old man with primary hepatocellular carcinoma had received a liver transplantation...
