Primary abdominal cocoon with cryptorchidism: a case report

Background: We report a rare case of primary abdominal cocoon with bilateral cryptorchidism.

Case presentation: The patient had a history of laparoscopic surgery for bilateral cryptorchidism 6 years earlier. He was admitted to the hospital again due to intestinal obstruction. Surgery was performed on the patient after the failure of conservative treatment. The patient was diagnosed with primary abdominal cocoon. Instead of the greater omentum, many cocoon-like tissues surrounding the bowel were seen during operation. Abdominal surgery can increase the risk of intestinal adhesion, which is one of the main causes of intestinal obstruction, especially in patients with abdominal cocoon. We hypothesize that the surgery 6 years earlier to address transabdominal bilateral cryptorchidism accelerated the patient's intestinal obstruction.

Conclusion: This case implies that it is important for urologists to evaluate whether their patients exhibit abdominal cocoon before cryptorchidism surgery, to choose better surgical methods and reduce the risks of poor prognosis.
