Abstract
An inflammatory fibroid polyp (IFP), also known as Vanek's tumor, is an uncommon benign tumor typically found as a solitary, intraluminal polyp in the gastrointestinal (GI) tract. Chronic IFP is characterized by persistent or recurrent inflammatory features, distinct histopathological findings, and a potential for significant GI tract involvement. Typically, IFPs occur predominantly in the gastric antrum, small intestines, and recto-sigmoid colon. They initiate within the submucosal layer and extend into the lamina propria, resulting in a noticeable bulging of the mucosal layer. They may breach the mucosal barrier on rare occasions, leading to ulceration and bleeding. This ongoing bleeding can induce persistent blood loss and symptoms typical of hypovolemic shock. When of smaller size, these growths might be accidentally detected during an endoscopic examination. Conversely, if the lesions are sizable, they can prompt symptoms of obstruction like queasiness, retching, and abdominal discomfort. Here, we present a case of a 47-year-old female who underwent a screening colonoscopy and was found to have an IFP.

Abstract
Introduction Intussusception is a telescoping of a bowel segment into another and it can be a surgical urgency. Most adult intussusceptions arise from a lead point which can be benign or malignant. For this reason, intussusception in adults should undergo surgery. Here we describe a case of ileal inflammatory fibroid polyp (IFP), presenting with ileo-ileal intussusception and obstruction. Case report A 54-year-old Caucasian woman presented for acute abdominal pain. A radiography and a CT of the abdomen were performed, which showed signs of occlusion due to an ileo-ileal intussusception. An urgent laparoscopy was performed, the intussusception was extracorporeally reduced, the ileal segment involved was resected, and an ileo-ileal anastomosis was performed. The intussusception seemed to be caused by a 3-cm intra-mural lesion. Discussion Intussusception is a surgical concern. While most cases are idiopathic in children, 90% of adult intussusceptions are caused by underlying diseases. Therefore, intussusception in adults should undergo surgery. Radiology is necessary for the diagnosis: the CT scan helps localizing the lesion and shows pathognomonic signs. This case report analyzes an intussusception caused by an inflammatory fibroid polyp. Accurate diagnosis of IFP is only possible with histopathological examination, helped by immunohistochemistry. The differential diagnosis is important because some lesions are malignant. Conclusion We reported a case of intussusception caused by an IFP. The diagnosis was made with a CT scan together with intraoperative findings and histopathological examination, which excluded potential differential diagnoses. The patient underwent an explorative laparoscopy, with an ileal resection and anastomosis. Due to the risk of malignancy, surgery is mandatory.

Abstract
BACKGROUND Intussusception is an uncommon cause of intestinal obstruction in adults. The etiology of this disease differs from the children. Thus, its management depends on the possible etiology and is different from pediatric cases. AIMS We aimed to study the clinico-histopathological spectrum of the tumors and tumor-like lesions in the intussusception in adults. MATERIAL AND METHODS A retrospective review of the adult (> 18 years) intussusception cases was performed. The clinical data and follow-up were obtained. The histopathology was reviewed along with the special stains and immunohistochemistry for ascertaining a histopathological diagnosis. RESULTS Fifteen cases of adult intussusception were identified from 107 resected specimens of adult intestinal obstruction. The mean age was 44.5 years with a male/female ratio of 1.1:1. A definitive pathology could be ascertained in 80% of the cases (n = 12/15). Eight cases had benign non-neoplastic etiology (53.3%) (33.3% tumor-like lesions) while seven cases (46.7%) had neoplastic etiology (20% benign neoplastic; 26.7% malignant neoplastic). All cases of colonic or enterocolic intussusceptions were associated with neoplasia whereas 90% of the enteric intussusceptions occurred due to benign non-neoplastic causes. CONCLUSIONS: Non-neoplastic causes are predominant in the enteric intussusceptions while neoplastic causes are more commonly associated with colonic or enterocolic intussusceptions. The post-operative histopathological examination concludes on the adequacy of the index surgery or the provision of further management if required.

Abstract
We present a rare case of gastrogastric intussusception due to gastrointestinal stromal tumor (GIST) and the largest comprehensive literature review of published case reports on gastrointestinal (GI) intussusception due to GIST in the past three decades. We found that the common presenting symptoms were features of gastrointestinal obstruction and melena. We highlight the diagnostic challenges faced in low-resource countries. Our findings emphasize the importance of early clinical diagnosis in low-resource settings in order to guide timely management. In addition, histological analysis of the tumor for macroscopic and microscopic characteristics including mitotic index and c-Kit/CD117 status should be obtained to guide adjuvant therapy with imatinib mesylate. Periodic follow-up to access tumor recurrence is fundamental and should be the standard of care.

Abstract
BACKGROUND AND AIM Vanek's tumor is a rare solitary lesion that is non-neoplastic, and arises from the submucosa of the gut. The most commonly affected sites are the stomach and the ileum [1]. IFP causing intestinal obstruction is uncommon and that ileo-ileal intussusception has been reported in the literature rarely. We present a case of an ileo-ileal intessuception in a patient who presented with acute on chronic pain abdomen and anorexia. CT abdomen & pelvis revealed a 46 × 36 mm intraluminal mass in the left iliac fossa causing ileo-ileal intussusception. CASE PRESENTATION A 60 years old gentleman was brought to the A&E with a history of intestinal obstruction. He was examined and admitted to the surgical unit. CBC revealed unique feature of reactive thrombocytosis apart from a low hemoglobin and a raised TLC. His CT scan demonstrated findings of ileo-ileal intussusception. After an informed written consent, patient underwent an exploratory laparotomy and had resection and anastomosis of the bowel. Histopathology of the specimen revealed findings compatible with IFP. Patient made an uneventful recovery post-operatively and was sent home in the next few days. On follow-up, the patient was doing well and had no complaints of abdominal pain or anorexia. CONCLUSION Vanek's tumor although a rare entity, should be considered in each case of acute abdomen and physicians and surgeons need to have a high degree of suspicion in such cases. Moreover, IFP can cause reactive thrombocytosis that gets resolved after a post-operative period of 6-8 weeks.

Abstract
AIM We evaluated the aetiological factors, diagnoses and treatment outcomes of adult cases of invagination of the intestine, or intussusception. We elucidated the role of ultrasonography (USG), computed tomography (CT) and other techniques in the diagnosis of such cases. PATIENTS AND METHODS Six patients with sufficient medical data, all of whom were followed-up and treated for intussusception at Safa Hospital, General Surgery Clinic, Istanbul, Turkey, between July 2008 and December 2013, were enrolled. RESULTS The site of intussusception was the small bowel in five cases. The aetiopathology was benign in 5 (83.3%) cases and included inflammatory fibroid polyp (IFP) and adhesion. The malignant case was adenocarcinoma. The bowel segments involved were ileoileal in five cases and ileocolic in one case. CONCLUSIONS USG and CT aided with the diagnosis. Although more rare in adults than in children, cases of ileus presenting with acute abdominal disorder, particularly those with an uncertain diagnosis, should be considered possible intussusception cases.

Abstract
Inflammatory fibroid polyps (IFPs), or Vanek’s tumor, are one of the least common benign small bowel tumors. IFP affects both sexes and all age groups, with a peak of incidence in the fifth and seventh decades. They can be found throughout the gastrointestinal tract but most commonly in the gastric antrum or ileum. The underlying cause of IFPs is still unknown. Genetic study of IFP showed mutations in platelet derived growth factor alpha in some cases. At the time of diagnosis most IFPs have a diameter of 3 to 4 cm. The lesions have always been recorded as solitary polyps. Symptoms depend on the location and the size of the lesion, including abdominal pain, vomiting, altered small bowel movements, gastrointestinal bleeding and loss of weight. IFPs arising below the Treitz ligament can present with an acute abdomen, usually due to intussusceptions. Abdominal computed tomography is currently considered the most sensitive radiological method to show the polyp or to confirm intussusceptions. Most inflammatory fibroid polyps can be removed by endoscopy. Surgery is rarely needed. Exploratory laparoscopy or laparotomy is frequently recommended as the best treatment for intussusceptions caused by IFP. The operation should be performed as early as possible in order to prevent the intussusceptions from leading to ischemia, necrosis and subsequent perforation of the invaginated bowel segment. This report aims at reviewing the diagnosis, etiology, genetics, clinical presentation, endoscopy, radiology, and best treatment of IFP.

Abstract
INTRODUCTION Inflammatory fibroid polyps (IFPs) are rare and small benign lesions throughout the digestive tract. The most common location is gastric antrum, but rarely at the upper part. Clinical manifestations of IFPs usually include intestinal obstruction, intussusception, abdominal pain, nausea and vomiting, but rare massive digestive tract hemorrhage. PRESENTATION OF CASE We describe a rare case presenting with massive gastrointestinal bleeding due to a huge gastric fundus IFP (11 cm). Finally, the patient was treated successfully by the laparoscopic assisted partial gastrectomy (LAPG) and recovered uneventfully. To our knowledge, this is the first reported case presenting with massive alimentary tract hemorrhage due to giant gastric fundus IFP. DISCUSSION Giant IFP rarely originates in the gastric fundus, but occasionally results in serious consequence, such as massive gastrointestinal bleeding. It is important to recognize IFP because it responds favorably to operation with no relapse or metastasis. CONCLUSION In the differential diagnosis of alimentary hemorrhage of uncertain etiology, gastric IFP should be considered. For huge gastric IFP, laparoscopic therapy is an apt choice.

Abstract
This is a case report of a 10-year-old boy who presented with features of acute intestinal obstruction. Clinical examination revealed distended abdomen, visible bowel loops, and a lump in the right upper quadrant of the abdomen. Clinically, the diagnosis of intussusception was suspected and confirmed on sonography examination. Exploration of the abdomen revealed ileo-colic intussusception. Manual reduction of intussusception was possible except the last part that had an intraluminal solitary polyp (3 × 4 cm) occupying the 3/4th of the lumen of the terminal ileum. Segmental resection of the ileum containing polyp was done, and the ileal continuity was restored with ileo-ileal anastomosis. His post-operative recovery was uneventful. Histologically, it was consistent with the inflammatory intestinal polyp without any evidence of malignancy.

Abstract
Adult intussusception is an uncommon disease requiring surgical intervention. The aim of this study is to discuss the surgical alternatives and share our experience in the treatment of adult patients with intussusceptions formed as a result of polyps. The retrospective study included 16 adult patients who underwent surgery after the diagnosis of intestinal invaginations resulting from polyps between the years 2000 and 2011. Sixteen patients (seven males and nine females; mean age, 48.18 years; range, 18 to 76 years) presented with intestinal intussusceptions. Although a preoperative diagnosis was carried out in 11 (68.75%) patients, the diagnosis was made intra-operatively in five patients (31.25%). Among the patients, seven (43.8%) had undergone emergency surgeries and nine (52.8) had elective surgery. The invagination in 12 patients (75%) was located in the small intestine, in two patients (12.5%) in the colon, and in a further two patients (12.5%), it was ileocecally located. Ten patients (62.5%) had segmental resection 1 anastomosis; three patients underwent (18.8%) segmental resection 1 enterostomy, and three (18.8%) received hemicolectomies. In adults, surgical treatment is always the primary option in intussusceptions resulting from polyps. Although the surgical method of choice in colonically located ones is en bloc resection without reduction, because the polyps located in the small intestine are usually of a benign nature, segmental resection with reduction should be performed in elective surgery and segmental resection without reduction should be performed in emergency cases.

Abstract
AIM: To give an overview of the literature on intussusception due to inflammatory fibroid polyp (IFP).
METHODS: We present a new case of ileal intussusception due to IFP and a literature review of studies published in English language on intussusception due to IFP, accessed via PubMed and Google Scholar databases. For the search, the keywords used were: intussusception, IFP, intussusception and IFP, intussusception due to IFP, and IFP presenting as intussusception. The search covered all articles from 1976 to November 2011.
RESULTS: We present a 38-year-old woman who was admitted 10 d after experiencing abdominal pain, vomiting, and nausea. Ultrasonography demonstrated small bowel intussusception. An ileal intussusception due to a mass lesion 50 cm proximal to the ileocecal junction was found during laparotomy. Partial ileal resection and anastomosis were performed. A diagnosis of ileal IFP was made based on the immunohistochemical findings. In addition, a total of 56 reports concerning 85 cases of intussusception due to IFP meeting the aforementioned criteria was included in the literature review. The patients were aged 4 to 81 years (mean, 49 ± 16.2 years); 44 were women (mean, 51.8 ± 14.3 years) and 41 were men (mean, 46 ± 17.5 years). According to the location of the IFP, ileal intussusception was found in 63 patients, while 17 had jejunal, three had colonic, and two had ileojejunal intussusception.
CONCLUSION: Although IFPs are rare and benign, surgery is the only solution in case of intestinal obstruction. Differential diagnosis should be made via immunohistochemical examination.

Abstract
Inflammatory fibroid polyps are rare benign tumors of the GI tract, that commonly present with intestinal obstruction as a result of intussusceptions in the small bowel. A 39-year old man visited our clinic with an asymptomatic polypoid mass in the distal ileum that was identified on abdominal computed tomography for postoperative surveillance after total gastrectomy due to previously diagnosed early gastric cancer. Retrograde double-balloon enteroscopy was performed to diagnose the ileal mass and a complete resection of the polyp was performed using snare for polypectomy without complications. The final histological finding was an ileal inflammatory polyp. Balloon-assisted enteroscopy is a valuable modality to diagnose and treat small bowel lesions in lieu of surgical procedures in selected cases.
