It is important to predict how many individuals of a predator species can survive in a given area on the basis of prey sufficiency and to compare predictive estimates with actual numbers to understand whether or not key threats are related to prey availability. Rugged terrain and low detection probabilities do not allow for the use of traditional prey count techniques in mountain areas. We used...

To the Editor, Phytobezoars, concretions of undigested food, are believed to remain silent and resolve spontaneously (1). Patients with symptomatic gastric bezoars usually present with small bowel obstruction (2). Endoscopic fragmentation and extraction with biopsy forceps, Dormia baskets, and polypectomy snares via overtube, which are the main treatment options in recent years, have many side ...

Stone formation within the intestinal lumen is called enterolith. This stone can encroach into the lumen causing obstruction and surgical emergency. Jejunal obstruction by an enterolith is a very rare entity and often missed preoperatively. To our knowledge, most cases of jejunal obstruction, secondary to stone, were associated with biliary disease (cholecystoenteric fistula), bezoar, jejunal d...

Bezoars are foreign bodies impacted in the digestive tract resulting of their ingestion and accumulation, involving mainly the stomach. The most common types are phytobezoars, containing vegetables, fiber and seed, and the trichobezoar, made of hair. The present case is the description of a 25-year-old female with nonspecific dyspeptic symptoms associated to intestinal habit change. The diagnos...

We report a case of a 79 year old man with a known benign anastomotic stricture presenting with large bowel obstruction. At laparotomy the obstruction was found to be caused by a large sesame seed bezoar. Seed bezoars are well known to cause impaction in the rectum but have never been previously reported to cause large bowel obstruction. We recommend that patients with known large bowel strictu...
