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...

Anomalies of the appendix are extremely rare, and a horseshoe appendix is even rarer. A literature search has revealed only five reported cases. In this report, we present a case of a horseshoe appendix.A 78-year-old man was referred for further examination following a positive fecal occult blood test. A mass in his ascending colon was detected on colonoscopy, while computed tomography showed that it was connected to the appendix. Tumor invasion derived from the ascending colon or appendix was suspected. We diagnosed ascending colon cancer prior to laparoscopic ileocecal resection...

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...

INTRODUCTION: Although bowel paralysis accompanying acute appendicitis is well known, mechanical bowel obstruction as a direct consequence of appendicitis remains a rare, but potentially life-threatening, acute abdomen. The aim of our literature review was to find all documented cases of this particular complication and compare them with our own case study. METHODS: We searched the PubMed database for relevant articles published from 1963 to 2015. The study included patients for whom direct links between appendicitis and strangulation of the terminal ileum were found, and for which the disease course had been documented in detail...

Adenocarcinoma arising in an ileal diverticulum are very rare. A 66-year-old man was recognized to have high serum CEA level and periappendiceal polycystic tumor in CT findings. Colonoscopy showed no abnormality in the ileocecal mucosa. However, the patient was suspected of appendiceal adenocarcinoma by PET/CT, which revealed FDG uptake with SUVmax of 3.9 in the tumor, and underwent radial surgery by single-incision laparoscopic surgery. Intraoperative findings showed the mass in the mesenterium of the terminal ileum but not the abnormality of the appendix...

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...

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...

BACKGROUND AND OBJECTIVES: The mobile cecum is an embryologic abnormality and has been associated with functional colon disease (chronic constipation and irritable bowel syndrome). However, unlike functional disease, the primary treatment is operative, using laparoscopic cecopexy. We compare the epidemiology and pathophysiology of mobile cecum syndrome and functional colon disease and propose diagnostic and treatment guidelines. METHOD: This study was a case-control series of 15 patients who underwent laparoscopic cecopexy...

Post-transplant lymphoproliferative disorder (PTLD) is a life-threatening complication of solid organ transplantation. We herein report a case of PTLD after living-donor liver re-transplantation (reLDLT) for recurrent primary sclerosing cholangitis (PSC), for which complete response was achieved by surgical resection and rituximab. A 47-year-old man, who had undergone living-donor liver transplantation (LDLT) twice at age of 43 and 45 years for end-stage liver disease firstly for PSC and secondary for recurrent PSC, suffered liver dysfunction due to an acute cellular rejection (ACR) 17 months after reLDLT...

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...

INTRODUCTION: Appendicular actinomycosis is a rare disease produced by cecal appendix invasion by Actinomyces gender bacteria after a predisposing cause that disrupts mucosal barrier, such as acute appendicitis. The highest frequency appears in adults; however, there are cases in paediatric age described in literature. The aim of this article is to introduce a case of appendicular actinomycosis in a child with atypical presentation and to review the literature. CLINICAL CASE: 10-year-old boy transferred to our hospital due to intraoperative finding at a different centre of a right flank tumor, without identification of cecal appendix...

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...

We report the case of a patient with Crohn's disease who initially presented with a ceco-urachal fistula. The patient was a 31-year-old female who underwent an appendectomy 6 years before presenting to our institution. She had a one-year history of diarrhea, and had recently developed polyuria and a sensation of residual urine. She was admitted with fever and lower abdominal pain. Endoscopy and computed tomography revealed a ceco-urachal fistula, which was consistent with Crohn's disease. An urachal resection was performed, which included partial cystectomy and ileocecal resection...

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...

BACKGROUND: Visceral pain is a common symptom of several gastrointestinal disorders. Despite tremendous progress in understanding its basic mechanisms, it remains a significant health challenge for clinicians. The present study quantified the intensity of visceral pain using ileocecal ligament traction on an inflamed ileum in goats. MATERIALS AND METHODS: A total of 36 male goats weighing 20.05±2.1 kg were randomly allocated equally into a 2,4,6-trinitrobenzenesulfonic acid (TNBS) group (n=18) and a saline group (n=18)...

Bacterial infections present a serious challenge to healthcare practitioners due to the emergence of resistance to numerous conventional antibacterial drugs. Therefore, new bacterial targets and new antimicrobials are unmet medical needs. Rhodanine derivatives have been shown to possess potent antimicrobial activity via a novel mechanism. However, their potential use as antibacterials has not been fully examined. In this study, we determined the spectrum of activity of seven rhodanine derivatives (compounds Rh 1-7) against clinical isolates of Gram-positive and Gram-negative bacterial strains and Candida albicans...
