Obscure gastrointestinal bleeding from a large jejunal lipoma treated using an endoscopic unroofing technique with double balloon enteroscopy: a case study.

Small intestinal lipomas are rare, but may cause obscure gastrointestinal bleeding. The endoscopic unroofing technique excises only the upper third of the lipoma and allows both histological confirmation and complete treatment with minimal risk of perforation. We present a rare case of obscure gastrointestinal bleeding caused by a jejunal lipoma. A 75-year-old man on antiplatelet therapy presented to our department with melena and anemia. Computed tomography revealed he had a 45-mm jejunal submucosal tumor with fat attenuation. Endoscopic resection using an endoscopic unroofing technique with double balloon enteroscopy was successfully performed. The tumor was confirmed to be a lipoma.

[A Case of Jejunal Cancer Treated by Laparoscopic Partial Jejunectomy].

The patient was a 30s male visited our hospital with the complaints of abdominal pain and melena. The internal medicine physician could not detect the cause of the melena by upper and lower gastrointestinal endoscopy. Although the patient resolved with a fast as conservative management so he left our hospital once, he relapsed nausea and abdominal pain. He visited our department. We performed surgery under a preoperative diagnosis of intestinal obstruction. The histopathological diagnosis was moderate differentiated jejunal adenocarcinoma(Stage ⅡA). At present, 1 year 7 months since surgery, the patient survives although with lymphnode recurrence.

Surgical resection of undifferentiated pleomorphic sarcoma (UPS) with jejunal perforation, a suspected case of metastasis of lung cancer.

Undifferentiated pleomorphic sarcoma (UPS) in the gastrointestinal tract is rare. According to the diagnostic criteria after the World Health Organization 2013 reclassification, there has been only one case of UPS with perforation of the gastrointestinal tract. A 71-year-old man who was undergoing outpatient chemotherapy at the department of respiratory medicine of our hospital for lung cancer and brain metastasis, was admitted to our hospital with sudden high fever and abdominal pain. A computed tomography scan showed free air in the abdominal cavity with thickening of part of the jejunal wall. We suspected jejunal metastasis of lung cancer and performed emergency surgery for acute peritonitis due to gastrointestinal perforation in the same area. A Bormann type 2 tumour was found in the jejunum with perforation. The histopathological diagnosis was UPS. Ten months have passed since the surgery, and there has been no recurrence of UPS and no significant change in lung cancer. Primary UPS of the gastrointestinal tract is rare, and cases with perforation are extremely rare. Currently, ten months have passed since the surgery, and no recurrence has been observed. We encountered a case of UPS in which it was difficult to distinguish metastasis from lung cancer to the jejunum, and the emergency surgery gave us the chance to confirm the definitive diagnosis and save the patient's life.

[A Case of Primary Jejunal Cancer Treated with Laparoscopic Jejunectomy with Appearance of Ileus].

An 83-year-old man visited our hospital for vomiting. Chest-abdominal computed tomography(CT)revealed that a tumor whose inside was imaged in the jejunum about 15 cm after leaving the Treitz ligament was pointed out, and dilation of the oral intestinal tract of the tumor was observed. Upper gastrointestinal endoscopy showed a type 3 circumferential tumor at the jejunum. He was diagnosed with obstructive ileus due to jejunal cancer. Laparoscopic-assisted partial jejunal resection was performed. Although the patient was followed up without chemotherapy, CT showed multiple lung and liver metastases and a mass lesion was found in the right entire chest, and a biopsy revealed skin metastasis 6 months after the operation. The patient is being followed up 10 months after surgery, there is no progression of liver, lung, and skin metastasis.

Massive Ascites Caused by Primary Diffuse Large B-cell Lymphoma of the Jejunum: A Case of a Rare Initial Symptom.

A 74-year-old man presented with abdominal swelling. Computed tomography revealed massive ascites and localized thickening of the small intestinal wall. Enteroscopy showed ulcerative lesions along the circumference of the jejunum. Histological examination showed dense proliferation of large lymphoid atypical cells, and immunohistochemistry showed CD20 and CD10 positivity, CD3 negativity, and Ki67 labeling index >80%. Cytology of the ascitic fluid revealed large lymphoid cells. These findings suggest that small intestine primary diffuse large B-cell lymphoma (DLBCL) caused the ascites. Massive ascites as an initial symptom of primary DLBCL of the jejunum is rare. Herein, we describe this unusual presentation.

Unusual presentation of a giant jejunal gastrointestinal stromal tumor.

AIM: Gastrointestinal stromal tumours (GISTs) are rare tumours. Tumour rupture is an additional adverse prognostic factor and should be recorded, regardless of whether it took place before or during surgery. CASE REPORT: A case report of hemoperitoneum from spontaneous rupture of a gastrointestinal stromal tumor of the jejunum is presented. The patient underwent an urgent laparotomy. An "en bloc" resection was performed. CONCLUSION: The information in the literature is examined. Spontaneous rupture of the tumor with concomitant hemoperitoneum is an important prognostic factor in these patients. The hemoperitoneum contributes to a worse prognosis because of its ability to produce peritoneal seeding KEY WORDS: Gist.

[Inflammatory fibroid polyp in the jejunum - a case report].

Inflammatory fibroid polyps (IFP) are rare type of benign tumours found in the gastrointestinal tract. IFP´s are in most cases small in size and without symptoms but can cause intussuception and haemorrhage. We present a case of a 25 year old female who presented with abdominal pain and symptoms and signs of anemia, hemoglobin was 36 g/L upon arrival. Further workup revealed a large tumor in the small intestine. The patient underwent a partial resection of the proximal jejunum. Pathology of the specimen showed inflammatory fibroid polyp.

Misdiagnosis of multiple synchronous small bowel adenocarcinomas as intestinal tuberculosis: a case report.

BACKGROUND: Small bowel adenocarcinoma (SBA) is a rare malignancy that primarily occurs in the duodenum. Multiple synchronous SBA is unique rare and difficult to diagnose due to non-specific disease presentation. Protocols to identify multiple synchronous SBA during early disease stages are urgently required. CASE PRESENTATION: An elderly man experienced left lower abdominal pain and melena for 3 months. Abdominal CT showed thickening of the multiple segmental small intestinal walls. As the patient had pulmonary tuberculosis simultaneously, he was misdiagnosis as intestinal tuberculosis and received anti-spasm therapy. The treatment delayed radical resection surgery and the patient underwent palliative segmental resection of the jejunum after 4 months due to intestinal obstruction. Resected specimens showed multiple synchronous SBA (five tumors). The patient accepted chemotherapy postoperatively. Six months postoperatively, the patient died of brain metastasis. CONCLUSIONS: We highlight how multiple synchronous SBA is rare and easily misdiagnosed. We should rule out multiple synchronous SBA when diagnosing intestinal diseases (e.g. inflammatory bowel disease, IBS). Intestinal tuberculosis may also be one of the risk factors for multiple synchronous SBA. High-risk patients should be assessed for known tumor makers, and receive gastroscopy, enteroscopy or capsule endoscopy. Doctors should obtain the pathology under endoscopy to the greatest possible degree. For suspected patients, laparotomy should be performed.

A case of jejunal neurofibroma in von Recklinghausen's disease with active hemorrhage, detected and located with gastrointestinal bleeding scintigraphy: A case report with literature review.

A 69 year old patient was admitted to hospital with massive gastrointestinal hemorrhage. The clinical presentation of the patient, except for bleeding, was dominated by the presence of neurofibromatosis type 1 - Von Recklinghausen disease. The patient was referred to multislice computed tomography (CT) angiography, magnetic resonance imaging (MRI), esophagogastroduodenoscopy and colonoscopy, which were performed without successful detection of the bleeding site. The MRI examination showed the existence of a tumor located in the small pelvis. After that, gastrointestinal bleeding scintigraphy (GIBS) with technetium-99m (99mTc) pyrophosphate in vivo labeled erythrocytes was done. Gastrointestinal bleeding scintigraphy showed active intraluminal bleeding from the projection of jejunum, which flowed through the small intestine to the descending colon and the sigmoidal and rectal segment of the colon. Surgical resection of the abdomen revealed the existence of tumors in the jejunum with active bleeding and resection and anastomosis was done. Histopathological verification showed intestinal neurofibroma. In this case GIBS showed usefulness in proving the existence of active bleeding in the small intestine and its localization, and it was of a great help in planning the surgical treatment of a patient.

Ruptured desmoid tumor imitating acute appendicitis - a rare reason for an emergency surgery.

BACKGROUND: Desmoid tumors, also known as aggressive fibromatosis, are extremely rare, accounting for less than 3% of soft-tissue sarcomas and less than 0,03% of all neoplasms. The diagnosis is usually delayed because of the lack of specific symptoms, and can sometimes lead to serious and, even fatal complications. CASE PRESENTATION: We report the case of a 27-year-old male patient presenting with the clinical picture of acute appendicitis. During the operation, we found a tumor in the jejunum with a necrotic zone and perforation on its surface, causing hemorrhagic effusion into the abdominal cavity and subsequent peritonitis. The tumor was removed with negative margins via resection of the small bowel. The final histological result showed aggressive fibromatosis. CONCLUSIONS: Aggressive fibromatosis remains a serious problem with the possibility of locally aggressive behavior with high rates of recurrence. Sometimes, its clinical and macroscopic recognition can be immensely tricky. As shown by our patient, on rare occasions, desmoid tumors can lead to acute surgical abdomen requiring an emergency operation.
