Mechanical upper bowel obstruction caused by a large trichobezoar in a young woman: A very unusual case report.

Background: Bezoars usually compile human fibers and debris. A special form of bezoar in case of psychologically altered individuals is the trichobezoar. It consists of voluntarily swallowed hair bulks and is normally removed gastroscopy. Trichobezoars leading to ileus have rarely been reported.

Case Summary: A 24-year-old female patient presented to the emergency room with abdominal pain, nausea, and vomiting for 3 d. Her previous medical and psychiatric history was unremarkable. Laboratory analysis showed iron deficiency anemia, leukocytosis, and elevated liver enzymes. An abdominal CT scan revealed a dense structure in the patients' stomach which turned out to be a huge trichobezoar completely obstructing the pylorus. The trichobezoar had to be removed surgically. During her postoperative course, a subcutaneous seroma formed. After a single puncture, the rest of the recovery process was unremarkable, and the patient recovered fully.

Conclusion: A mechanical bowel obstruction is a potentially life-threatening event for every patient. In our case a young female was suffering from severe symptoms of an obstruction which might have resulted in serious harm without successful surgical management.
