Abstract
BACKGROUND

Among all forms of heterotopic ossification, heterotopic mesenteric ossification (HMO) is rare, with fewer than 100 reported cases to date. Postoperative early small bowel obstruction caused by HMO is even rarer, presenting extremely high surgical risks, the potential for multiple surgeries, and a poor prognosis. There have been no reported cases of conservative treatment for resolving such early postoperative obstruction.

CASE SUMMARY

A 57-year-old male presented with severe postoperative small bowel obstruction shortly after undergoing open radical resection for transverse colon cancer. Laparotomy revealed extensive adhesions in the proximal jejunum and mesentery, making it too difficult to relieve without injuring the small bowel. Additionally, multiple fixed nodules were found in the mesentery during the operation. Pathology confirmed the presence of heterotopic ossification. The patient was treated with methylprednisolone on postoperative day 1, which gradually relieved his symptoms.

CONCLUSION

Hormone therapy may have a potential role in treating small bowel obstruction caused by early HMO after operative intervention.

Core Tip: In this case, we present a unique treatment approach for resolving early postoperative heterotopic ossification of mesentery-induced small bowel obstruction. There was difficulty dissecting the small bowel obstruction during the second surgery, thus we tried treatment with methylprednisolone, which gradually relieved the patient’s bowel obstruction, thereby providing a new and effective strategy for early postoperative heterotopic ossification of the mesentery-induced small bowel obstruction and hypothesizing that early postoperative heterotopic ossification of the mesentery is a specific postoperative inflammatory response.
