Background/aims: The neoplasms of the small intestine are rare and the preoperative diagnosis is difficult. The aim of this study is to review difficulties in diagnosis, treatment options and important prognostic factors.
Methodology: Fifteen patients who underwent surgical resection for intestinal tumors from 1990 to 2000 in the Third Surgical Clinic of Izmir Atatürk Training and Research Hospital were reviewed retrospectively. Age, symptoms, diagnostic methods, operative procedures, and their effects on prognosis were evaluated.
Results: Seven patients were male and eight were female. The mean age was 52.3 years (27-77). Eight patients underwent urgent intervention and seven had elective surgery. Three cases were diagnosed as small bowel tumor preoperatively. The radical resection of the small bowel neoplasm was possible in 12 patients (80%), eight of whom being malignant and four of whom being leiomyoma. Three patients with leiomyoma are still alive for 3.5, 6 and 9 years but one patient died perioperatively because of respiratory distress syndrome. Two cases with lymphoma survived for 16 and 37 months while another two have been still alive for 7 and 8 years. The patients who had malignant epithelial tumor, leiomyosarcoma, and malignant mesenchymal tumor survived for 17, 54, and 20 months, respectively. The patient with malignant tumor of endocrine origin has still been living for 3 years.
Conclusions: As a result we concluded that better evaluation of signs and symptoms may facilitate the diagnosis; and the most important prognostic factors are early diagnosis and radical surgery.

Exposure to vanadium (V) occurs through the ingestion of contaminated water, polluted soil, V-containing foods and medications, and the toxicity and absorption during the small intestine phase after oral ingestion play crucial roles in the ultimate health hazards posed by V. In this study, the human colon adenocarcinoma (Caco-2) cells were selected as an intestinal absorption model to investigate the uptake and cytotoxicity of vanadyl sulfate (VOSO) and sodium orthovanadate (NaVO). Our results confirmed the cytotoxic effects of V(IV) and V(V) and revealed a greater toxicity of V(IV) than V(V) towards Caco-2 cells.

Interstitial cells of Cajal in the plane of the myenteric plexus (ICC-MY) serve as electrical pacemakers in the stomach and small intestine. A similar population of cells is found in the colon, but these cells do not appear to generate regular slow wave potentials, as characteristic in more proximal gut regions. Ca handling mechanisms in ICC-MY of the mouse proximal colon were studied using confocal imaging of muscles from animals expressing GCaMP6f exclusively in ICC.

Background: Small bowel adenocarcinoma (SBA) is a rare malignancy with few established chemotherapy options and a dismal prognosis. We investigated the expression of claudin 18.2, nectin-4, human epidermal growth factor receptor 3 (HER3), and programmed death-ligand 1 (PD-L1) in SBA to identify potential antibody drug targets and analyzed associated clinicopathological features and prognosis.

Hawthorn leave flavonoids (HLF) are widely used as an herb or dietary supplements for cardio-cerebrovascular diseases. However, its gastrointestinal absorption behavior and mechanism have not been disclosed. In this study, gastrointestinal absorption and its regulation of 4''-O-glucosylvitexin (GLV), 2''-O-rhamnosylvitexin (RHV), vitexin (VIT), rutin (RUT) and hyperoside (HP) in HLF were investigated using in vitro, in situ and in vivo models.

Lymphoma is the most common neoplasia in the intestine of cats. According to ACVIM consensus statement, low-grade intestinal T-cell lymphoma (LGITCL) represents a monomorphic infiltration of the lamina propria or epithelium or both of cats with small, mature, neoplastic (clonal) T lymphocytes. Despite the importance as contributing factors of inheritance and environment in the pathogenesis of LGITCL, the chronic inflammatory status plays a fundamental role.
