Carcinoid tumors are the most common form of gut neuroendocrine tumors, however, they rarely present with small bowel obstruction. We present a case of a 65-year-old woman without prior abdominal operations who presented with symptoms of small bowel obstruction. Computed tomography (CT) showed multiple air fluid levels and a transition point in the left mesentery with two soft tissue densities at the same level. The patient was taken to the operating room for surgical exploration, which showed two intramural masses in the mid and distal jejunum, which surgical pathology showed to be stage IIIB carcinoid tumor...

PURPOSE: One of the rarest gastrointestinal neoplasm is small bowel cancer. Experience with its treatment modalities is limited. Stereotactic ablative radiation therapy (SABR) has improved, with image-guided radiation therapy becoming a curative option in many tumors. Especially when surgery cannot be performed due to comorbidities, SABR provides a good toxicity profile and an excellent tumor control rate owing to its specific schedule: high dose on a limited and well-defined area. METHODS: An 83-year-old man had arterial hypertension and congestive cardiomyopathy, with recent history of upper abdominal pain, weight loss over 10 kg, and progressive severe fatigue...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

Brunner's gland adenoma is an extremely rare benign small bowel neoplasm, often discovered incidentally during upper gastrointestinal endoscopy or radiological diagnostics. In few cases, it tends to cause gastrointestinal hemorrhage or intestinal obstruction. We report here our experience with a 47-year-old woman with a Brunner's gland adenoma of more than 6 cm in size, located in the first part of the duodenum and causing gastrointestinal bleeding. Initially, we performed a partial endoscopic resection using endoloop and snare alternatively to prevent severe bleeding...

Autoimmune enteropathy (AIE) is rare but damaging. The lack of consistent objective findings makes diagnosis a challenge. A 45-year-old male developed noninfectious diarrhea with significant weight loss and electrolyte abnormalities. Computed tomography delineated enteritis. Colonoscopy and esophagogastroduodenoscopy showed villous atrophy, chronic inflammation, and ulceration of the terminal ileum and cecum. Pathology showed cryptitis with apoptosis and abscesses throughout the small and large bowel and absent goblet cells...

BACKGROUND/AIMS: Balloon-assisted endoscopy allows us to diagnose gastrointestinal (GI) stromal tumors (GISTs) in the small bowel including endoscopic ultrasonography and taking biopsy. The aim of this study was to retrospectively clarify clinical and endoscopic characteristics of small bowel GISTs using double-balloon endoscopy (DBE). METHODS: We reviewed 25 patients who underwent DBE and were diagnosed with GISTs. The risk of GISTs was stratified using the National Institute of Health (NIH) consensus criteria...

Calcifying fibrous tumor (CFT) is a rare benign mesenchymal lesion known to arise at multiple body sites that may clinically mimic other more aggressive lesions in the gastrointestinal (GI) tract. In this study we describe the clinicopathologic findings of 28 GI tract CFTs. Tumors predominantly arose in middle aged adults with a slight female predominance. The most commonly involved sites were small bowel and colon, followed by stomach and appendix. Tumors ranged from 0.3 to 9.3cm (median 1.4cm) and submucosa was the most commonly involved layer...

Heparanase activity is highly implicated in cellular invasion and tumor metastasis, a consequence of cleavage of heparan sulfate and remodeling of the extracellular matrix underlying epithelial and endothelial cells. Heparanase expression is rare in normal epithelia, but is often induced in tumors, associated with increased tumor metastasis and poor prognosis. In addition, heparanase induction promotes tumor growth, but the molecular mechanism that underlines tumor expansion by heparanase is still incompletely understood...

A 40-year-old man presented to our department with chief complaints of nausea and abdominal pain, and was diagnosed with small intestine ileus. After hospitalization, he underwent intestinal tract decompression using an ileus tube. A small bowel tumor was suspected as the cause of the intestinal obstruction. We then performed laparoscopic surgery for diagnosis and resection. In the intraoperative findings, stenosis near the small intestine tumor could be confirmed. The patient therefore underwent laparoscopic resection of a segment of the small intestine...

A 75-year-old woman who had undergone a Hartmann's operation for sigmoid colon cancer 2 years ago was hospitalized because she experienced small bowel obstruction several times. She had a treatment history of 6 other cancers, including 5 gastrointestinal tract cancers. However, the obstruction was relieved by conservative therapy each time. In September 2015, she was hospitalized for ileus. Abdominal computed tomography revealed that the lumen of intestine was partially dilated. Subsequently, a long tube was inserted, but the dilatation of the small intestine was not fully recovered...

Small bowel carcinoma has poor prognosis. The basis of treatment is surgical resection. There are no established guidelines for chemotherapy. We report a case in which we performed surgical resection of recurrent jejunal carcinoma. A 62-year-old woman underwent laparoscopic partial resection of the small intestine for primary jejunal carcinoma. The final diagnosis was T3N0M0, fStage II A. After 16 months of follow-up, she developed abdominal pain and vomiting. We diagnosed recurrence of jejunal carcinoma in the ileum and right ovary...

A 65-year-old woman who was diagnosed with unresectable Stage IV sigmoid colon cancer underwent transverse colostomy with double orifices. Although KRAS gene mutation was observed, we could not administer bevacizumab because of the risk of bleeding from the primary tumor and peritumoral abscess. We started bi-weekly XELOX therapy but bloody bowel discharge continued. We planned extended resection of the primary tumor in order to control the bleeding and perforation. Sigmoidectomy, partial resection of the left ureter and small intestine, partial hysterectomy, bilateral salpingo-oophorectomy, and umbilical tumor resection were performed and the patient was discharged on the 10th day after surgery...

BACKGROUND: Mesenchymal stem cells (MSCs) may have beneficial effects in reversing intestinal damage resulting from circulatory disorders. The hypothesis of this study is that MSCs increase antioxidant capacity of small bowel tissue following intestinal ischemia reperfusion (I/R) damage. METHODS: A total of 100 rats were used for the control group and three experimental groups, as follows: the sham control, local MSC, and systemic MSC groups. Each group consisted of 10 animals on days 1, 4, and 7 of the experiment...

Primary malignant small bowel tumor as a rare kind of intestinal tumor is associated with a poor prognosis. The pathological types were various and complicated, such as adenocarcinoma, neuroendocrine tumor, malignant lymphoma, and malignant stromal tumor. The atypical early stage symptom resulted in difficult diagnosis at early stage, high misdiagnosis rate and lack of standard therapy schemes and means. In the past, X-ray, CT, MRI, and PET-CT were the main examination methods for primary small bowel tumor...

Small bowel tumors are rare tumors. Duodenal tumors occur more commonly compared with other small intestinal tumors. To summarize the clinicopathological features of duodenal tumors, in the present study 44 cases of duodenal tumors were collected, and the comparative clinicopathological characteristics between tumors of the ampulla and non-ampulla, the choice of treatment, and differences in the prognosis, were analyzed. The pathological type identified was predominantly adenocarcinoma; periampullary duodenal tumors were almost classifiable as adenocarcinoma in terms of their type...

Perivascular epithelioid cell tumor (PEComa) of the small intestine is extremely rare, and there is no established treatment at the present time. In 10% of patients with PEComas, genetic alterations of tuberous sclerosis complex have been reported. These genetic alterations activate mechanistic target of rapamycin (mTOR) in AMP-activated protein kinase and Ras/mitogen-activated protein kinase pathways, resulting in high mTOR activity. Since 2007, several cases of treatment with mTOR inhibitors in advanced PEComa have been reported...

Diffuse malignant pleural mesothelioma (MPM) is an aggressive tumor that originates from the surface of the pleura. Approximately 70% of cases are associated with chronic asbestos exposure. MPM is regarded as an incurable disease, with a median survival of ~2 years following intensive multimodality treatment. Pancreatic cancer is a malignancy also associated with a poor prognosis, with only 2% of patients surviving for 5 years. The majority of patients with pancreatic cancer are diagnosed with an advanced stage of disease and experience a poor response to therapy...

The use of immune checkpoint inhibitors to treat malignant tumors with microsatellite instability is an emerging new modality. This is based on the observations that these tumors may have a high mutation rate-thus a potential source of tumor-specific neoantigens-and harbor infiltrating cytotoxic T cells in response, suggesting that they may be particularly susceptible to immune checkpoint therapy. PUBMED and ASCO library were systematically reviewed to identify all relevant data that involved the use of immune checkpoint inhibitors in the treatment of cancers with microsatellite instability...
