AIM: Isolated colon lipomas are rare benign tumors. We herein conducted a systematic review of the literature to identify clinical characteristic, diagnostic and treatment options. MATERIALS AND METHODS: A search for relevant studies was conducted in Scopus, Embase and Medline databases until the end of May 2014. The search terms were "colonic lipoma and colon lipoma". Articles were included if they had information on symptoms, lipoma characteristics and type of procedure performed...

BACKGROUND: Colonic lipomas (CL) are rare benign adipose tumours usually found incidentally during colonoscopy. Endoscopic resection of symptomatic large CL remains controversial, since significant rates of perforation have been reported. In recent years, a novel technique for removal of large CL has been described, consisting of looping and ligating the lipoma with a nylon snare. The aim of our study was to evaluate the safety and efficacy of the "loop and let go" technique for large colon lipomas in a large case series...

A colon lipoma is a remarkably rare tumor. In most cases, the tumors are asymptomatic and small in size, need to be differentiated from malignant tumors, and do not need any special treatment. Selection of the right surgical strategy depends on the status of bowel, as well as the size and the location of tumor. We encountered two patients with giant submucosal lipomas that had induced intussusceptions: one with a lipoma in the transverse colon and the other with a lipoma in the ascending colon. The diagnoses were made by using histological examinations...

Lipomas are common benign mesenchymal tumors. They can develop in virtually all organs throughout the body. Colonic lipomas are uncommon, benign, submucosal adipose tumors that are usually asymptomatic. Large lipomas can cause symptoms such as constipation, abdominal pain, rectal bleeding, and intussusception. We report a case series of 2 colonic submucosal lipomas with varying clinical presentations, elaborating the importance of computerized tomography imaging in the diagnosis and preoperative planning.

BACKGROUND: Intussusception is a relatively common cause of intestinal obstruction in children but a rare clinical entity in adults, representing fewer than 1% of intestinal obstructions in this patient population. Colonic lipomas are uncommon nonepithelial neoplasms that are typically sessile, asymptomatic and incidentally found during endoscopy, surgery, or autopsy. CASE PRESENTATION: A 55-year old man visited our emergency department with severe abdominal pain, multiple episodes of vomiting, abdominal distension...

PATIENT: Male, >60 FINAL DIAGNOSIS: Colonic lipoma Symptoms: Rectal bleeding • abdominal pain • fatique • abdominal distention MEDICATION: - Clinical Procedure: Laparoscopic resection Specialty: General surgery. OBJECTIVE: We aimed to review and discuss the clinical picture and management of 4 patients who underwent laparoscopic colonic resection with a definitive pathology of colonic lipoma. BACKGROUND: Colonic lipomas are rare benign nonepithelial tumors of the colon...

INTRODUCTION: Acute colonic intussusception occurring in the absence of organic cause is uncommon in adults. PRESENTATION OF CASE: We report acute colonic intussusception in a 46-year-old female; clinical evidence of a palpable mass, abdominal pain and bloody mucoid stools appeared a few hours after hospital admission. Multislice CT-scan confirmed the clinical diagnosis and surgical exploration revealed right colonic obstruction caused by intussusception of the cecum into the ascending colon...

Colonic lipomas are uncommon nonepithelial neoplasms that are typically sessile, asymptomatic and incidentally found during endoscopy, surgery, or autopsy. We present a very rare case of a 34-year-old female patient with symptomatic pedunculated cecal lipoma causing intermittent colo-colonic intussusception. Despite adequate imaging studies, definite preoperative diagnosis was not established and the patient underwent exploratory laparotomy. Intraoperatively, intussusception of the cecum into the ascending colon was found and right hemicolectomy was performed...

Colonic lipomas larger than 2 cm in diameter are likely to be symptomatic. In some cases a complication is the first clinical sign. Massive lower intestinal bleeding or obstruction, acute bleeding, prolapse or perforation or, rarely, acute intussusception with intestinal obstruction require urgent surgery. Diagnosis is often made following colonoscopy, which can also have a therapeutic role. Imaging procedures such as CT has a secondary role. Patients with small asymptomatic colonic lipomas need regular follow up...

BACKGROUND: Lipoma of the large intestine is rare, with a reported incidence ranging between 0.2% and 4.4%. We present a case of a giant colonic lipoma causing descending-colonic intussusception. AIMS: A 54-year-old woman visited our emergency room with sudden onset of intermittent abdominal cramps. She was nauseous and had rectal blood loss for three days. Physical examination showed a tender palpable mass in the left lower abdominal quadrant. Rectal examination showed little blood on the glove...

Lipomas of the colon are relatively rare benign tumors. Colo-colonic intussusception is an unusual complication of colonic lipoma. We report the case of a 79-year-old man who presented with spasmodic, self-limiting abdominal pain associated with rectal bleeding. Colonoscopy revealed a submucosal mass suggestive of a benign tumor but that was too large for endoscopic resection. CT scan demonstrated an endoluminal fatty mass in the transverse colon, typical of lipoma, and suggested colo-colonic intussusception due to the mass...

AIM: The aim of this study is to present our experience in colonic lipomas. PATIENTS AND METHODS: We present 4 patients (1 male, 3 females) of mean age 65.5 years (range, 61-72 years) treated for single colonic lipomas. The diameters of the lesions were 4.5, 4, 3.5 and 2.5 cm, respectively. In 3 cases, colonic lipomas were located within the cecum, while in one patient within the descending colon, proximally to the splenic flexure. RESULTS: Lipomas of diameter greater than 3 cm caused nonspecific symptoms...

OBJECTIVE: The purpose of this article is to comprehensively survey all CT-detected ileocolic and colocolic intussusceptions at a cancer institute. MATERIALS AND METHODS: Using the free-text string "intus," the radiology information database of Memorial Sloan-Kettering Cancer Center was searched over a 13.5-year period for abdominopelvic CT scan reports. Images were rereviewed by an attending radiologist for the presence of a bowel-within-bowel appearance involving the colon...

Adult intussusception is a rare clinical presentation and often not considered clinically in the differential diagnosis of adult patients with vague abdominal complaints. A 44-year-old woman visited our emergency department with sudden onset of intermittent abdominal pain. Diagnostic imaging revealed an intussusception caused by a submucosal lipoma of the sigmoid. A laparotomy was performed and the diagnosis was proven by histological examination. Submucosal lipomas are usually asymptomatic but may cause bleeding, obstruction, intussusception, or abdominal pain and thus mimic a malignancy...

Intussusception is a pediatric condition that rarely presents in adults. Colonic lipomas 4 cm and more in diameter can cause colonic intussusception leading to emergency operation. Surgical resection of the involved segment must be the procedure of choice. We report a case of colonic intussusception caused by colonic lipoma in an adult. The patient underwent operation, and histopathological examination of the specimen confirmed the diagnosis of colonic submucosal lipoma.
