Intestinal amyloidosis is a rare and underdiagnosed systemic disease, which is characterized by the extracellular deposition of proteins that are grouped into amyloid fibers. This entity is rare and is usually a form of presentation in the context of systemic amyloidosis, the diagnosis of which is based on the presence of amyloid in histology. The clinic is usually non-specific; chronic diarrhea, weight loss, abdominal pain and bloating; Gastrointestinal bleeding is a very rare manifestation. The case of a 61-year-old woman with symptoms of weight loss, abdominal distension, nausea, vomiting and long hair is presented. Tomographically, a wall thickening of jejunal loops with contrast uptake was evidenced, a finding that was corroborated by a double-balloon anterograde stereoscopy in which multiple were evidenced. The pathology shows distorted and ulcerated villous architecture with positive histochemistry for Congo Red and LAMBDA (+++) immunohistochemistry. In addition, bone marrow aspirate and bone biopsy compatible with infiltration of Lambda chain monoclonal multiple myeloma were performed. During the hospital stay, the patient developed complications such as chronic malnutrition, recurrent infection and several episodes of intestinal subocclusion; characterized by intestinal pneumatosis; due to multiple episodes of these complications, the patient died. Within clinical practice in gastroenterology, intestinal amyloidosis as part of the differential diagnosis of upper gastrointestinal bleeding is infrequent, so a history of diagnosis of multiple myeloma or other monoclonal gammopathy associated with light chains is crucial for early diagnosis and adequate treatment.

The presence of esophageal foreign body (EFB) is a common emergency in gastroenterology. The protocol for management and endoscopic intervention can be variable among institutions.

Objective: to define the clinical characteristics of EFB in adults, its radiological and endoscopic diagnosis, and complications based on a sample of patients in a gastroenterology center.

Materials and methods: case series of patients admitted from the emergency department and referred to the gastroenterology department with a presumptive diagnosis of EFB. Clinical variables were collected, as well as characteristics, comorbidities, time of evolution and diagnostic opportunity, confirmatory studies, and complications.

Results: 84 subjects, 70% men, mean age 45 (range: 17-87; SD 12.5) years. Urgent upper endoscopy was performed in 98.8% of the patients, with an average in-hospital stay of 2.5 days. 93% had no associated underlying pathology, in 6/84 (7.14%) patients structural or functional esophageal pathology was documented. 59/84 (70.2%) patients consulted in the first 24 hours, in 57.6% the presence of foreign body was confirmed endoscopically. In 67/84 (79.76%) patients radiography was performed prior to endoscopy, of which 62/67 (92.5%) had an abnormal result. Seventy percent of confirmed EFB were fish bones. The most frequent site of localization was in the cricopharyngeal region in 90% of the cases. In 66/84 (78.6%) subjects there was absence of complications, followed by deep laceration in 10/84 (11.9%) cases. In 3/84 (3.6%) cases complications requiring surgery were identified.

Conclusions: Endoscopic intervention in the first 24 hours is an opportune moment to identify complications and provide the indicated treatment.
