omental infarction

OBJECTIVE: We hypothesized that therapeutic efficacy may be augmented by a combination of placing a sheet immersed in ONO-1301SR, a slow-release synthetic prostacyclin agonist-inducing multiproangiogenic cytokines, over the left ventricle and a pedicled omental flap in a chronic myocardial infarct heart. METHODS: A minipig chronic myocardial infarction was generated by placing an ameroid constrictor ring around the left anterior descending artery for 4 weeks. The minipigs were then assigned into 4 groups of 6 each: sham, omental flap only, ONO-1301SR only, and ONO-1301SR combined with an omental flap (combined)...

Idiopathic omental infarction (IOI) is a rare cause of right-sided abdominal pain, mimicking serious surgical pathology. It occurs in <4 in 1000 cases of appendicitis. IOI can be a challenge to diagnose, as features may mimic appendicitis, and therefore in young patients, may only be discovered on laparoscopy. CT features can be diagnostic, but due to its rarity the diagnosis may be unclear. The literature supports both conservative management and surgical management (to expedite symptom resolution). We present a case of IOI and discuss our management and learning from the case...

AIM: To review children with Omental Infarction (OI) and the role of Ultrasound Scan (US) in its diagnosis and management. METHODS: Cases of OI were identified retrospectively from 2004 to 2014 through screening of admission coding, pathology databases and radiology records. Demographic, clinical and pathological data were extracted from case records. MAIN RESULTS: 30 cases were identified (17 male, 13 female). Mean age was 10.7years (range 3...

A 58-year-old female presented to the emergency department with intermittent right upper quadrant pain and nausea. On examination, the patient was tender and Murphy's sign was elicited. A presumptive diagnosis of acute cholecystitis was made but an ultrasound of the abdomen revealed a thin-walled gallbladder without calculi. A computed tomography (CT) scan of the abdomen and pelvis demonstrated fat stranding involving the greater omentum and the right paracolic gutter. The patient was diagnosed with a focal omental infarction and underwent emergency laparoscopic surgery...

Ovarian cancer (OC) is an aggressive disease with few valuable biomarkers and effective therapies. In this study, we aimed to elucidate biomarkers associated with OC metastasis into the omentum. We performed comprehensive screening of non-coding RNAs (ncRNAs) between matched primary OC and omental metastasis using the Agilent human lncRNA Array V3.0 microarray. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) was used to validate the microarray results at the mRNA level. Microarray revealed 235 ncRNAs changes, and we validated the top four differential changed genes in an additional 27 paired samples with RT-qPCR...

Omental infarction is a rare cause of acute and non-specific abdominal pain. We report a case of a 46-year-old man who presented to the emergency room with right upper quadrant cramping pain that was of sudden onset. The patient's presentation was later diagnosed as an omental infarction, by an abdominal CT. After extensive work-up, it was revealed that the cause of the patient's omental infarction was secondary to a hypercoagulable state caused by antiphospholipid syndrome, based on his thrombophilia work-up...

Primary omental infarction (POI) is a rare cause of acute abdomen. Most patients have aggravating abdominal pain without gastrointestinal symptoms. Here, we report a case of omental infarction in a 50-year-old woman, who had left abdominal pain and intestinal obstruction. Preoperative computed tomography (CT) of the abdomen showed a left ovarian cyst measuring 6.0 cm × 4.5 cm but otherwise seemed normal initially. The white blood cell count was 9.71 × 10(9)/L, and D-dimer was 1.58 mg/L. Laparoscopic exploration was performed 1 day after admission because of peritonitis and intestinal obstruction...

INTRODUCTION: Mesenteric and omental mesothelial cysts are rare, accounting for only 1 in 100,000 hospital admissions for abdominal pain (Tan Jane et al., 2009) [1]. They are often discovered only on CT imaging, which is frequently non-definitive in identifying an exact tissue source owing to overlapping radiographic features with other masses (Stoupis et al., 1994) [2]. The symptoms manifested by such masses are also nonspecific, favoring consideration of more frequently encountered problems in the scope of general surgery over cystic masses in the differential diagnosis...

BACKGROUND: Acute myocardial infarction (MI) leads to an irreversible loss of proper cardiac function. Application of stem cell therapy is an attractive option for MI treatment. Adipose tissue has proven to serve as a rich source of stem cells (ADSCs). Taking into account the different morphogenesis, anatomy, and physiology of adipose tissue, we hypothesized that ADSCs from different adipose tissue depots may exert a diverse multipotency and cardiogenic potential. METHODS: The omental, pericardial, and epicardial adipose tissue samples were obtained from organ donors and patients undergoing heart transplantation at our institution...

Introduction. Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is a common procedure in obesity surgery. The aim of an antecolic approach is to reduce the rate of internal herniation. Our aim is to make bariatric surgeons aware of another possible complication of antecolic LRYGBP. Methods and Results. We present a case report of omental torsion 24 months after antecolic LRYGBP presenting as an acute abdomen, suggesting appendicitis. During diagnostic laparoscopy, omental infarction due to torsion was observed...

Omental infarction is a rare condition which is being increasingly reported in the literature due to the advancement in imaging techniques and its typical computed tomography appearance. Accurate diagnosis of omental infarct can be made on computed tomography, thereby avoiding exploratory surgery. We report a case of conservatively managed primary omental infarct which was clinically thought to be acute pancreatitis.

Iatrogenic parasitic myomas are rare. The condition is defined by the presence of multiple smooth-muscle tumorous nodules in the peritoneal cavity. This may be attributable to seeding of myoma particles during uterine surgery. The clinical course is usually indolent. The disease is often asymptomatic and is usually discovered only incidentally. A 38-year-old woman who had undergone abdominal myomectomy 7 months prior presented with acute abdominal pain and a huge pelvic mass. We performed exploratory laparotomy...

Omental infarction is an uncommon cause of acute abdomen in the pediatric population. We report a case of a 4-year-old male child with right iliac fossa pain. The final diagnosis was made on ultrasound and computed tomography findings. This entity needs to be differentiated from acute conditions like appendicitis, avoiding surgery.

Unusual pathologies are occasionally found at laparoscopy when appendicitis is suspected. We present a case of strangulated inflammatory fibrous pseudotumour of the omentum presenting in a similar fashion to appendicitis. The infarcted omentum was excised, facilitating prompt resolution of symptoms.

Right lower quadrant pain is one of the most common indications for imaging evaluation of the abdomen in the emergency department setting. This article reviews important imaging findings associated with acute appendicitis as well as major differential considerations including: mesenteric adenitis, Meckel diverticulum, neutropenic colitis, right-sided diverticulitis, epiploic appendagitis, omental infarction, and inflammatory bowel diseaseRight lower quadrant pain is one of the most common indications for imaging evaluation of the abdomen in the emergency department setting...

Primary Segmental Infarction (PSI) of the greater omentum is rare. It usually presents as acute appendicitis and the diagnosis is made per operatively. We report a case of 22 years male who presented with history and clinical features suggestive of acute appendicitis. Laparoscopic appendicectomy was planned but during diagnostic laparoscopic phase, omentum was found infarcted in the right lower abdomen and the appendix was normal. Laparoscopic omentectomy of the infarcted segment was done and the patient had smooth recovery...
