Incidentally Detected Small Intestine Intussusception Caused by Primary Small Intestine Carcinoma on ^18F-FDG PET/CT
Nuclear Medicine and Molecular Imaging, 2017Co-Authors: So Won OhAbstract:Small Intestine intussusception in adults is a rare condition mainly caused by primary or metastatic Small Intestine malignancy. Here, we present a 72-year-old male patient who was diagnosed with Small Intestine cancer that was presented as Small Intestine intussusception on hybrid ^18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). The patient was initially referred for an abnormality on a chest radiography and severe anemia. FDG PET/CT showed the lung lesion in the right upper lobe of lung as a high FDG uptake mass. Accidentally, FDG PET demonstrated another intense hypermetabolic intraluminal lesion in the Small Intestine accompanied with intussusception shown as a circumferential hypermetabolic wall. By pathologic examination, the patient was diagnosed as primary Small Intestine cancer with lung metastasis. This case highlights usefulness of hybrid FDG PET/CT to identify unexpected malignancy.

Assessment of blood flow in the Small Intestine by laser Doppler flowmetry: Comparison of healthy Small Intestine and Small Intestine in Crohn's disease
Journal of Gastroenterology, 1997Co-Authors: Satoshi Tateishi, Sumitaka Arima, Kitaro FutamiAbstract:Blood flow and blood distribution were investigated in 40 patients with normal Small Intestine and the relation between blood flow and the morphological features of Crohn's disease was examined in 11 patients with Crohn's disease by laser Doppler flowmetry from the serosal side during surgery. In normal Small Intestine, blood flow was measured at six points: upper, middle, and lower Small Intestine, each of the mesenteric borders, and the antimesenteric surface. In Crohn's disease, macroscopically normal tissue and affected lesions were observed in detail by intraoperative endoscopy after blood flow measurement. The blood flow values in the normal Small Intestine gradually decreased from the upper to the lower Small Intestine. As the level of inflammation progressed in Crohn's disease the blood flow values gradually decreased; the exudative stage of Crohn's disease (aphthoid ulcer) showed blood flow values that were slightly below those in macroscopically normal tissue. These results are the first to demonstrate decreased blood flow in affected lesions in Crohn's disease and changes in blood flow according to the degree of inflammation in vivo.

Non-Meckel Small Intestine Diverticulitis
Case Reports in Gastroenterology, 2017Co-Authors: Shamim Ejaz, Raghu Vikram, John R. StroehleinAbstract:Non-Meckel Small Intestine diverticulitis can have many manifestations and its management is not well-defined. We report 4 unselect cases of Small Intestine diverticulitis; all patients were seen by the same physician at the Emergency Center at The University of Texas MD Anderson Cancer Center between 1999 and 2014. The median age at diagnosis of these patients was 82 years (range, 76–87 years). All 4 patients presented with acute onset of abdominal pain, and computed tomography scans showed characteristics of Small Intestine diverticulitis unrelated to cancer. Most of the diverticula were found in the region of the duodenum and jejuno-ileal segments of the Small Intestine. The patients, even those with peripancreatic inflammation and localized perforation, were treated conservatively. Non-Meckel diverticulitis can be overlooked in the initial diagnosis because of the location of the diverticulosis, the age of the patient, and the rarity of the disease. Because patients with non-Meckel Small Intestine diverticulitis can present with acute abdominal pain, non-Meckel Small Intestine diverticulitis should be considered in the differential diagnosis of patients with acute abdominal pain, and computed tomography scans can help identify the condition. Because of the rarity of non-Meckel Small Intestine diverticulitis, few studies have been published, and the data are inconclusive about how best to approach these patients. Our experience with these 4 elderly patients indicates that non-Meckel Small Intestine diverticulitis can be treated conservatively, which avoids the potential morbidity and mortality of a surgical approach.

Complicated Small Intestine diverticulitis
Nederlands tijdschrift voor geneeskunde, 2019Co-Authors: Robert J S Coelen, L Maurits De BrauwAbstract:Complicated Small Intestine diverticulitis Background Diverticula do not only occur in the colon but also in the Small Intestine albeit less frequently. Small Intestine diverticula are usually asymptomatic. Acute complications, such as intestinal obstruction, bleeding or diverticulitis with or without abscess or perforation, are rare. Case description An 85-year-old male presented to the emergency department with abdominal pain since two weeks and a palpable mass in the upper left abdomen. Laboratory tests revealed significantly elevated infection parameters. Computed tomography imaging of the abdomen revealed ileus of the Small Intestine as well as a Small bowel faeces sign and wall thickening. Upon laparotomy, we saw there was Small Intestine diverticulitis and covered perforation. We carried out a partial resection of the Small Intestine. Patient recovered smoothly and has not had any symptoms since then. Conclusion Asymptomatic Small Intestine diverticula require no treatment, while complicated diverticulitis often requires surgery.
