Gastrointestinal Amyloidosis as a Cause of Anemia: Rare and Rarely Considered.

Gastrointestinal involvement in amyloidosis is reported in 3% of cases, mostly associated with multiple myeloma. An elderly man with chronic kidney disease presented to the hospital after a large melenic bowel movement. The patient was tachycardic and anemic to 3.8 g/dL on admission and was transfused blood. Endoscopy and colonoscopy were unremarkable. Subsequently, the patient had 2 more admissions for severe anemia requiring blood transfusion. Repeat esophagoduodenoscopy with capsule endoscopy were unremarkable. The patient was diagnosed with monoclonal gammopathy of undetermined significance by hemoglobin electrophoresis, and endoscopy biopsy revealed intestinal amyloidosis in a duodenal specimen. The patient's recurrent anemia was attributed to bleeding from gastrointestinal amyloidosis, in the absence of other identifiable sources of anemia, and was managed with intravenous iron infusions.

Rectal foreign body of a shattered glass bottle; Case report of unexpected late post-operative hemorrhage managed transanally.

INTRODUCTION: Retained rectal foreign bodies are commonly implicated in patients engaging in erotic behavior. The foreign bodies vary widely, however, penetrating rectal wounds are uncommon and often complicate the retrieval of the object. The rich vascular bed of the rectal mucosa provides additional bleeding complications. PRESENTATION OF CASE: A 55-year-old male presented with active bleeding after intentional insertion of a glass bottle into the rectum which shattered. Partial retrieval via proctoscopy was followed by an exploratory laparotomy with a diverting colostomy, mucous fistula, and presacral drainage. Postoperative course was complicated by severe hematochezia. Colonoscopy was performed in the operating room found actively bleeding ulcers at sites of previously lacerated mucosa; one pulsating, protruding, vessel was visible. Clips were placed over the vessel with cessation of bleeding. Barium enema at three months follow revealed no leaks allowing for reversal of the colostomy. DISCUSSION: This case of operative retrieval of a rectal foreign body is unique because it displays deviation from commonly used algorithms are periodically needed to optimize patient recover. CONCLUSION: The utilization of minimally-invasive colonoscopy prior to additional surgical intervention in post-operative rectal bleeding following a rectal foreign body retrieval may improvie patient recovery time, functionality, and long-term outcomes.

Large right atrial myxoma containing gastric heterotopia presenting with dyspnea and bilateral leg edema due to pulmonary emboli and cardiovascular obstruction: the first known report of gastric heterotopia in the cardiovascular system.

A 52-year-old male presented with progressive dyspnea, bilateral leg edema, and elevated central venous pressure due to a large right atrial myxoma that caused vascular obstruction and pulmonary emboli. The myxoma contained gastric heterotopia. Other unusual features of this atrial myxoma included its large size, right atrial location, and attachment to the right atrial wall. Although gastric heterotopia has been reported throughout the gastrointestinal tract, and occasionally in other organs, this is the first report of gastric heterotopia in the cardiovascular system. This report confirms and extends previous reports of glandular elements or enteric glands within atrial, or cardiac, myxomas. The clinical presentation of the currently reported patient is explained as follows: the elevated central venous pressure resulted from cardiovascular obstruction and the dyspnea from multiple pulmonary emboli due to the large atrial myxoma. In this case, the clinical presentation was not attributable to the gastric heterotopia. The association of gastric heterotopia with atrial myxoma may, however, be clinically important because of the propensity of gastric heterotopia in the gastrointestinal tract to produce complications. The reported association may provide clues to the histogenesis of these two entities.
