11/54. Inflammatory fibroid polyp of the ileum causing intussusception: report of two cases with emphasis on cytologic diagnosis.

    Inflammatory fibroid polyp (IFP) of the gastrointestinal tract is a type of inflammatory pseudotumor or inflammatory myofibroblastic tumor that occurs most commonly in the stomach but also in the small and large bowel. Small-bowel IFP usually presents with intussusception. The purpose of the current study is to describe cytological features of this lesion with differential diagnoses since pathologists may be called on to render a diagnosis on fine-needle aspiration. Two cases of IFP are described with diagnostic features on imprint smears. Both were middle-aged obese women with a history of prior intra-abdominal surgical procedures who presented with signs of intestinal obstruction and were found to have a tumor causing intussusception. At intraoperative consult, scrape cytology specimens showed cellular smears with a heterogeneous population of myofibroblasts, inflammatory cells and vessels. The features together with clinical history are sufficient to suggest the diagnosis. IFP is a lesion with a characteristic morphology. The differential diagnosis includes several other lesions, hence triage of cytological specimen for culture, electron microscopy, and immunohistochemistry is important in facilitating a correct diagnosis. Although a surgical procedure may still be necessary once a diagnosis of IFP is made, treatment may be tailored for a less aggressive process.

12/54. Multiple somatostatin- and gastrin-containing carcinoids of the duodenum: report of a case treated by pancreas-sparing duodenectomy.

    A 59-year-old Japanese man was incidentally discovered to have multiple polyps in the duodenum by endoscopy during a health checkup. Laboratory studies showed an elevated level of serum somatostatin. The mutation of the MEN1 gene was not observed. An endoscopic examination revealed multiple polypoid lesions in the bulbus and in the second portion of the duodenum. An upper gastrointestinal series also showed the multiple polypoid lesions in the bulbus, and in the descending and horizontal portions of the duodenum. The biopsy specimen showed small monotonous cells with round nuclei compatible with a carcinoid tumor. The tumor cells were positive for somatostatin and gastrin. Based on the clinical diagnosis of multiple carcinoids of the duodenum, a pancreas-sparing duodenectomy was performed. Macroscopic findings showed about 30 polypoid lesions throughout the duodenum. The biggest one was not over 10 mm in size. A histological examination revealed well-demarcated carcinoid tumors located in the submucosal layer. Immunohistochemically, the tumors were diffusely positive for somatostatin and were scatteringly positive for gastrin. The patient's postoperative course of treatment was uneventful and his postoperative serum somatostatin went down to normal range. The pancreas-sparing duodenectomy is a safe and effective treatment in patients with multiple carcinoids of the duodenum, that are smaller than 1 cm in size.

13/54. Intra-operative total enteroscopy for the management of Peutz-Jegher's syndrome.

    We present a case of Peutz-Jegher's syndrome in an 18 year old female who was followed for gastrointestinal polyps for 13 years from the age of 5 years. The patient was treated four times with surgical or endoscopic polypectomy for gastrointestinal polyps. At the age of 14 years, a combined surgical and endoscopic approach for the management of Peutz-Jegher's syndrome was carried out. A large polyp of the ileum required enterotomy for its removal, and another smaller polyp of the upper jejunum was identified and removed by intra-operative total enteroscopy via the anus. Intra-operative enteroscopy allows one to identify polyps that would previously have been missed. A more complete polypectomy can be performed using this technique, allowing the patient with Peutz-Jegher's syndrome a longer interval between laparotomies and a reduction in symptoms attributed to polyps.

14/54. A case of inflammatory fibroid polyp causing small-bowel intussusception in which retrograde double-balloon enteroscopy was useful for the preoperative diagnosis.

    We showed a newly developed method, retrograde double-balloon enteroscopy, to be useful for preoperative diagnosis in a case of inflammatory fibroid polyp accompanied by small-bowel intussusception. A 64-year-old woman was admitted to our hospital with small-bowel intussusception. Results of radiographic and ultrasonographic examination were suggestive of a small-bowel mass. Retrograde double-balloon enteroscopy was performed in an attempt to make a preoperative diagnosis. Endoscopic observation, in combination with histological findings derived from endoscopic biopsy, was suggestive of an inflammatory fibroid polyp. The patient then underwent laparotomy with minimal incision, which revealed a polypoid mass leading to a jejunojejunal intussusception, without bowel necrosis, and a partial small-bowel resection was performed. The pathological diagnosis was an inflammatory fibroid polyp.

15/54. 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.

16/54. endoscopy-assisted resection for multiple polyps of the small intestine in peutz-jeghers syndrome: a father and daughter story.

    peutz-jeghers syndrome is an infrequently encountered disease with potential complications including bleeding, intestinal obstruction, intussusception, and malignant transformation. We report on two patients, father and daughter, with peutz-jeghers syndrome who were admitted to hospital with similar complaints of abdominal pain. The father was 37 years old and the daughter was 17. physical examination and laboratory tests revealed small intestinal intussusception in both patients. In the daughter, the intussuscepted segment was resected. An electrosurgical snare was also used for enteroscopic excision of multiple jejunal and ileal polyps. In the father, two 4-cm polyps were surgically resected while an enteroscopic surgical snare was used for polyps of smaller size. Both patients were discharged on postoperative day 7.

17/54. 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.

18/54. 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.

19/54. Crohn's disease of the small intestine with polypoid configuration.

    We describe three patients with Crohn's disease of the small intestine with a polypoid configuration. In two patients, the polypoid masses were the only radiologic abnormalities and were suggestive of jejunoileal lymphoma and terminal ileal adenomas. The diagnosis of Crohn's disease was established only at laparotomy. In the third patient, a polypoid mass simulating a sessile adenoma was seen along with other typical features of ileitis and was recognized preoperatively as a manifestation of the ileitis. The resected ileal segments of all three patients showed mural thickening, luminal narrowing and distortion, and mucosal ulceration and fissuring. The asymmetry of the mural thickening and the resultant luminal narrowing simulated sessile polyps to which mucosal ulceration and fissuring gave a lobulated appearance.
