[Inflammatory fibroid polyp of the ileum presenting as intussusception: a case report in an adolescent]

Inflammatory fibroid polyp is an uncommon and benign submucosal lesion of the gastrointestinal tract. The maximal incidence is in the fifth and sixth decades. The main histological characteristics are diffuse inflammatory infiltrate with eosinophils and highly vascularized fibrocystic stroma. We report a case of 15-year-old patient who underwent emergency surgery because of acute intestinal obstruction as a result of an intussusception. The macroscopical study after segmental ileal resection showed a nodular lesion 3x2x2 cm, arising from the submucosa with an ulcerated surface. The pathologic diagnosis was ileal inflammatory fibroid polyp. Immunohistochemically, the cells reacted with vimentin and CD34. It has no malignant potential although extensive infiltration may occur. The etiology is unknown. We discuss the clinical, the pathological aspects and the possible etiological factors of the inflammatory fibroid polyp.

Adult ileal intussusception: an unusual emergency condition

Adult intussusception occurs infrequently and differs from the childhood condition in its presentation, cause, and treatment. Nonspecific symptoms can delay diagnosis; most cases are diagnosed at emergency laparotomy. Increased use of computed tomographic scanning to evaluate patients with abdominal pain can enhance reliable preoperative diagnosis. Treatment entails simple bowel resection in most cases. Reduction is controversial, especially in cases of colonic intussusception. This report describes the diagnosis and management of a case of adult ileal intussusception caused by an inflammatory fibroid polyp-a rare lesion of the gastrointestinal tract.

Intussusceptions arising from two different sites in a child with cystic fibrosis

Abdominal pain is common in individuals with cystic fibrosis (CF). We report on a 17-year old boy with CF and two recognized intussusceptions: the first colonic intussusception was presumed due to distal intestinal obstruction syndrome, and the second enteric one due to polypoid lesions containing heterotopic gastric mucosa. The presentation, pathology, management, and a literature review of intussusception in CF are discussed.

Multiple ileal polyps associated with gastrointestinal perforation in a 2-day-old neonate

We experienced a very rare case of a gastrointestinal perforation due to multiple ileal polyps. The patient was a 2-day-old boy who weighed 1,430 g at birth. At neonatal day 2 subdiaphragmatic free air was noted and an emergency operation was performed. During surgery a distended ileum approximately 5 cm in size was found approximately 40 cm distal from the ileocecum, and a perforation was discovered in the distended portion of the intestine. Approximately 8 cm of the ileum was resected, including the distended portion of the intestine, and an ileostomy was performed. Examination of the resected specimen revealed three pedunculated polyps with a perforation proximal to the polyps.

Distribution and prevalence of colorectal hyperplastic polyps using magnifying pan-mucosal chromoendoscopy and its relationship with synchronous colorectal cancer: prospective study

BACKGROUND AND AIM

Patients with multiple (hyperplastic polyposis) or large hyperplastic polyps (HPs) predominantly in the right-sided colon, have been reported to have an increased risk of colorectal cancer (CRC). This prospective study was conducted to clarify the distribution of various sized HPs using magnifying pan-mucosal chromoendoscopy and its relationship with synchronous CRC.

METHODS

Patients eligible for this study had an initial total colonoscopy. Indigo carmine dye was sprayed throughout the whole colon and rectum, and diagnoses were made using magnifying colonoscopy.

RESULTS

A total of 263 patients were enrolled, and a total of 3060 HPs were observed in 226 (86%) patients. The prevalence of patients with intermediate size (> or = 6 mm) HPs was 8.7% (n = 23) and that of patients with large HPs (> or = 10 mm) was 0.8% (n = 2). Of 3060 HPs, the numbers of diminutive (< 6 mm), intermediate size and large HPs were 3020, 38 and two, respectively, and 5.0%, 42.1% and 100% of these were located in the right-sided colon, respectively. Synchronous CRC was observed in 64 (24%) of 263 patients. Compared to patients without HPs, patients with intermediate size HPs showed a significant increase in odds ratio (OR) for synchronous CRC (OR = 4.9: 95% CI [1.3-18.2]), but there was no significant association between synchronous CRC and patients with diminutive or large HPs.

CONCLUSIONS

Compared to diminutive HPs, intermediate size and large HPs were predominantly located in the right-side colon. Moreover, intermediate size HPs were significantly correlated with synchronous CRC.

[Inflammatory fibroid polyp of the ileum causing intestinal invagination]

Inflammatory fibroid polyps are rare benign tumor-like lesions of the gastrointestinal tract. Most frequently they are localized in the gastric antrum but can develop anywhere in the GI tract. In the small intestine the ileum is the most common site, where these polyps can cause invagination and intussusception. This happened to the patient we describe here. The latest immunohistochemical, ultrastructural and molecular genetic studies are suggestive of dendritic cell origin of inflammatory fibroid polyps, with myofibroblastic differentiation in some cases.

Coexistence of Crohn's disease and inflammatory fibroid polyp of the small bowel. Report of a case and review of the literature

BACKGROUND/AIM

The Authors report a case of a woman aged 35, with concurrent appearance of Crohns disease and Inflammatory Fibroid Polyp of the terminal ileum.

CASE REPORT

The combination of the two disorders was clinically manifested as an obstructive ileus. On the operative table, a 4-cm polypoid mass causing intussusception of the bowel was obvious. The resected specimen of the ileum showed profound distention, several ulcerations and fissures. The histological examination confirmed the diagnosis of Crohn's disease coexisting with an Inflammatory Fibroid Polyp. Immunostaining of the lesion for actin showed focal positivity. However, staining for desmin, CD31, S100-protein, PGM-1 CD34, CD117, and bc1-2, was negative.

CONCLUSION

Coexistence of Inflammatory Fibroid Polyp with Crohn's disease causing obstructive ileus could be the first manifestation of the disease. The combination of the two disorders corroborates the reparative character of the lesion. Nevertheless, the exact etiopathogenetic relationship between the two entities remains obscure.

Epigastraglia with tarry stools in a middle-aged female caused by jejunal intussusception due to a hamartoma

Upper gastrointestinal (GI) hemorrhage is a common presentation to an emergency department. Often, the diagnosis is peptic ulcer disease in which vague or sharp abdominal pain is associated with bleeding. In contrast, intussusception is a rare cause of abdominal pain and coincident GI bleeding. In this case, we report a 41-year-old woman who had an intussuscepting jejunal obstruction due to a hamartoma of the small bowel. The diagnosis was established by ultrasonography. In review of the literature, abdominal pain and bleeding are two common manifestations of intussusception when the lesion originates in the small bowel. Intussusception is frequently included in the differential diagnosis of pediatric patients with coincident abdominal pain and bleeding. However, it is rarely mentioned as an adult cause of these two findings. Because of the delayed and nonspecific presentations of abdominal discomfort in adult patients with intussusception, the diagnosis is often delayed. This case points out the need for considering intussusception even in middle-aged patients whose initial presentation is concomitant bleeding and pain.

Inflammatory fibroid polyp of the ileum causing intussusception

Intussusception in adults is a rare cause for intestinal obstruction and is usually secondary to some lesion in the gastrointestinal tract GIT. We report a case of intestinal obstruction due to ileo-colic intussusception; an inflammatory fibroid polyp formed the leading edge of the intussusceptum, which is a rare polypoidal lesion of the GIT.

[Gastrointestinal inflammatory fibroid polyps. Clinical characteristics and follow-up in a series of 26 patients]

INTRODUCTION

Inflammatory fibroid polyp (IFP) is a protuberant lesion, located near the muscularis mucosae and composed of a proliferation of fusiform cells and conjunctive fibers surrounding capillaries and a variable inflammatory infiltrate. It is believed to be a poorly controlled inflammatory repair response. Our aim was to study the clinical, pathological and follow-up characteristics of a series of patients with IFP.

PATIENTS AND METHOD

We studied 26 IFPs from 25 patients (16 women and 9 men) registered between 1985 and 2001 in a specific register of 3 centers in the city of Gerona (Spain). The variables analyzed were age, sex and clinical presentation, IFP localization and size, mucosal characteristics and associated disease, as well as follow-up information. Routine statistical analyses were performed.

RESULTS

IFPs were antral in 16 patients, ileal in 7, jejunal in 2 and colonic in the remaining patient. Size determined whether they were symptomatic (35 +/- 13.6 mm) or asymptomatic (8.4 +/- 6.3 mm). Gastric polyps were significantly smaller than intestinal polyps. Symptomatic polyps (5 out of 16 gastric polyps and 9 out of 10 intestinal polyps) predominated in women and occurred at a significantly lower age than asymptomatic polyps (59.2 versus 74.1 years). Most gastric IFPs were associated with chronic atrophic gastritis while only one ileal polyp was associated with Meckels diverticulum. The mean length of follow-up was 60.6 months and, except in one patient who underwent incomplete resection, no recurrences of IFP were observed.

CONCLUSION

IFP is a heterogeneous entity, depending on age at presentation, sex, size and location in the digestive tract. IFP does not recur after resection. The association of gastric IFP and chronic atrophic gastritis could suggest a modulatory effect of the mucosa on IFP growth.

Risk of colorectal neoplasm in patients with acromegaly and its relationship with serum growth hormone levels

OBJECTIVES

Acromegalics have been reported to be at an increased risk of colorectal neoplasm. However, the magnitude of the risk is still controversial and the mechanism has not been fully investigated. In this study, we attempted to determine the magnitude of the association between acromegaly and colorectal lesions after taking into account age, gender, smoking status, and treatment status. In addition, we assessed the relationship between colorectal lesions and serum growth hormone (GH) levels in acromegalics.

METHODS

We conducted a case-control study by using 19 consecutive untreated patients (male:female = 11:8) who were newly diagnosed with acromegaly between 1990 and 2000. All patients underwent colonoscopy and received a histological diagnosis of colorectal lesions. Prevalence of hyperplastic polyp, adenoma, and carcinoma were compared with the prevalence in 76 controls matched for gender, age, and smoking status. Serum GH levels were compared between acromegalic patients with and without each type of colorectal lesion.

RESULTS

The prevalence of hyperplastic polyp, adenoma, and carcinoma were significantly higher in the acromegalic patients compared to the controls (p < 0.05, odds ratios; 8.3, 4.2, and 9.8, respectively). In acromegalics, the presence of hyperplastic polyps and carcinomas were significantly associated with higher serum GH levels after adjusting for the other lesions and age (p < 0.05).

CONCLUSIONS

After controlling for age, gender, smoking status, and treatment status, acromegaly was associated with significantly higher prevalence of colorectal hyperplastic polyp, adenoma, and carcinoma. High serum GH levels may be associated with the presence of hyperplastic polyp and carcinoma.

Adult intussusception secondary to inflammatory polyps

Adult intussusception is a rare entity that may present in the acute and subacute setting principally related to the degree of bowel obstruction. Preoperative diagnosis of this condition may be difficult. The intussusception is usually due to a definable intraluminal lesion, most probably neoplasia, unlike intussusception in children. We present the cases of two adult male patients with intussusception. The first presented with acute small-bowel obstruction secondary to a retrograde ileojejunal intussusception with a pseudopolyp as the lead point. This was possibly due to a retrograde ball-valve effect. The intussuscepting segment was resected. The second patient presented with unexplained chronic diarrhoea and an intussusception occurring within the caecum, as demonstrated at colonoscopy, with a terminal ileal pedunculated fibroid polyp as the lead point. A limited right hemicolectomy was performed. Both patients recovered uneventfully and have remained well. A brief literature review of adult intussusception complements the case reports, with an emphasis on the pathogenesis of inflammatory polyps and recommended surgical management.

Endoscopic band ligation for non variceal bleed

Endoscopic band ligation (EBL) is an infrequently used modality for treatment of non-variceal hemorrhage. We report the successful use of this technique for the management of bleed from blue rubber bleb nevus syndrome lesions and post polypectomy bleeding stalk.

Inflammatory fibroid polyp of jejunum causing jejuno-jejunal intussusception

Intussusceptions originating in the jejunum are rare. We report a 20-year-old woman who had a chronic jejuno-jejunal intussusception due to an inflammatory fibroid polyp manifesting in the post-partum period as peritonitis. Resection-anastomosis of the intussuscepted segment was done. She is well one year later.

A study of the symptomatology of hypertrophied anal papillae and fibrous anal polyps

BACKGROUND

The presence of Hypertrophied anal papillae and fibrous anal polyps are often ignored in proctology practice. But the experience is that they tend to produce minor but disturbing symptoms. This study is aimed to assay the impact and utility of attending these two conditions concurrently while dealing with cases of fissure in ano.

PATIENTS AND METHODS

The study was carried out in 136 patients with chronic anal fissure having concomitant hypertrophied anal papillae or fibrous anal polyps. After relieving sphincter spasm by sphincterotomy, the polyps or papillae were destroyed using the radio frequency device. A comparison was made for the associated complaints like pruritus, pricking sensation, wetness, crawling sensation in the anus etc. before and after the removal of papillae or polyps by an independent observer blinded to the procedure.

RESULTS

After one month of the procedure, the associated symptoms were reduced to a significant extent along with a nearly total decline in the primary complaints of pain and bleeding. There was significant reduction in pruritus (p=0.0003), discharge per anus (p=0.0006), crawling sensation in the anus (p=0.0004) and that of incomplete evacuation (p=0.001) At the follow up after 18 months, only 9 % of patients had recurrence of either anal fissure or symptoms like pruritus.

CONCLUSION

This study establishes that removal of hypertrophied anal papillae and fibrous polyps should be carried on a routine basis during surgical treatment of anal fissure. This would add to the effectiveness and completeness of the procedure.

[Potential use of current X-ray contrast studies in the detection of small intestinal polyps in the Peutz-Jeghers syndrome]

The paper presents the results of studies of the small bowel in 9 patients with the Peutz-Jeghers syndrome. The indications for the study were the clinical picture of gastrointestinal bleeding and the symptoms of ileus. The author's intubation enterographic procedure using the better composition of barium suspension and an infusion system for administering contract substances into the small bowel, an improved fractional contrasting procedure, and a procedure employing the agent Entero-view was applied for contrasting the small bowel. All the procedures revealed an obvious picture of polyposis of the small bowel. The minimum size of detected tumors was 0.3-0.4 cm in diameter. Emphasis is laid on the quantitative image of neoplasms with Entero-view and the therapeutic effect of intubation enterography in evolving small-small intestinal intussusception.

[Ileum inflammatory fibroid polyp revealed by intussusception. About one familial case]

INTRODUCTION

Acute ileum intussusception is a frequent and mostly benign condition in childhood. Conversely, it is a rare condition during adulthood and generally associated with an underlying malignancy. We report a familial form of benign inflammatory fibroid polyps, revealed by an acute ileum intussusception.

EXEGESIS

A 41-year-old man, whose mother had undergone three surgical procedures for acute ileum intussusception associated with inflammatory fibroid polyp, was admitted for a abdominal pain that started three month ago. The patient displayed alteration of the intestinal transit, weight loss and sub-occlusive syndrome. Upper and lower endoscopies, performed before admission, were normal. In the emergency room, the abdominal computed tomography-scan revealed an acute intussusception of the last loop of the small intestine, probably caused by a tumor and leading to an occlusive syndrome. Surgical resection and histological analysis concluded to an inflammatory fibroid polyp. Clinical outcome was excellent.

CONCLUSION

Inflammatory fibroid polyp is always a benign tumor. It is usually isolated, expressing itself mainly in the form of an acute intussusception when located in the small bowel. The familial form presented here is exceptional and illustrates the possibility of an inherited transmission of this disease. However the pathogenesis of this type of polyp is still unclear.
