Jejunal Amyloidoma - a rare cause of gastrointestinal bleeding

We report a case of localized amyloid tumor of the jejunum which presented with abdominal pain and gastrointestinal bleeding. We reviewed the pathophysiologic process that precipitates bleeding in this rare tumor. We also examined the documented radiologic and endoscopic features of amyloidosis of the small bowel in the light of our reported case. All with a view to add to the growing evidence on this rare tumor which will facilitate accurate diagnosis and management

Solitary Small Bowel Metastasis from Breast Cancer

The common sites of metastasis of breast cancer are bone, lung, and liver, but gastrointestinal metastasis from breast cancer is rare. We experienced a case of solitary ileal metastasis from breast cancer. A 45-years-old woman presented with melena for several weeks. She showed no other abdominal symptoms. Colonoscopy findings showed an ulcerative mucosal lesion in the terminal ileum, and biopsy was performed. Pathologic examination revealed metastatic carcinoma, originated from breast. The tumor cells were positive for estrogen receptor and negative for Cdx-2. She had had a previous medical history of bilateral breast cancer and undergone breast conserving surgery with sentinel lymph node biopsy for both breasts. The torso positron emission tomography scan at 19 months after surgery showed mildly increased uptake in the terminal ileum which was considered as inflammation. Finally, she was diagnosed with solitary ileal metastasis from breast cancer at 22 months after surgery

Feasibility of purely laparoscopic resection of locally advanced rectal cancer in obese patients

Abstract Background Totally laparoscopic (without hand-assist) resection for rectal cancer continues to evolve, and both obesity and locally advanced disease are perceived to add to the complexity of these procedures. There is a paucity of data on the impact of obesity on perioperative and oncologic outcomes for totally-laparoscopic rectal cancer resection (TLRR) for locally advanced disease. Methods In order to identify potential limitations of TLRR, a single-institution database was queried and identified 26 patients that underwent TLRR for locally advanced rectal cancers (T3/T4) over a three-year period. Patients were classified as normal-weight (NW, body mass index (BMI)=18.5 to 24.9kg/m2), overweight (OW, BMI=25 to 29.9kg/m2) and obese (OB, BMI >/= 30kg/m2). Perioperative outcomes, lymph node harvest and margin status were assessed. Results Seven patients were classified as NW (26.9%), 12 as OW (46.2%) and 7 as OB (26.9%). Age, tumor stage, gender and American Society of Anesthesiologists (ASA) scores were similar. OB had more co-morbidities (median 3.0, range 0.0 to 5.0 vs. 2.0, range 0.0 to 3.0 for NW and 1.0, range 0.0 to 3.0 for OW). Five patients had tumors Conclusion The perceived limitation that obesity would have on TLRR was not demonstrated by the analyzed data. Although our findings are limited by the modest sized cohort, the results suggest that it is reasonable to offer TLRR to obese patients with rectal cancer.</p
