Iliac Crest Herniation Secondary to Autogenous Bone Grafting Found on Osteopathic Examination.

Surgical repair of difficult or nonunion fractures is frequently performed with autogenous bone grafts, most commonly from the iliac crest. Complications from this procedure may include vessel injury, nerve injury, pelvic instability, bowel herniation, and ileus. The authors report a case of iliac crest herniation in a patient presenting with a small-bowel obstruction 2 years after anterior iliac crest graft harvest for an open reduction and internal fixation repair of a right humeral shaft fracture. An emergency operation revealed that the right colon had herniated through an opening in the right iliac crest. The appendix had adhered to new osseous bone formed postoperatively, requiring an appendectomy. The hernia defect was successfully repaired with polypropylene mesh. A high index of suspicion for graft site herniation is needed for patients with a history of iliac crest bone grafting who present with symptoms of abdominal pain, flank or hip pain, ileus, or small-bowel obstruction.

Oxaliplatin, fluorouracil, and leucovorin for patients with unresectable liver-only metastases from colorectal cancer: a North Central Cancer Treatment Group phase II study.

PURPOSE: Surgical resection of liver-only metastases from colorectal cancer has undergone extensive evaluation and review. The use of neoadjuvant chemotherapy to improve the likelihood of resection in disease that is not optimally resectable has not been as well studied. PATIENTS AND METHODS: Patients with liver-only metastases from colorectal cancer deemed not optimally resectable by a surgeon with expertise in liver surgery received fluorouracil, leucovorin, and oxaliplatin (FOLFOX4). Patients were periodically reassessed for resectability. Surgical response was classified as completely resectable (S-CR), partially resectable (S-PR), or unresectable (S-UR). Study design specified the accrual of 39 patients, with two or more S-CRs considered evidence of promising activity with respect to increasing the S-CR rate. RESULTS: Forty-two of 44 patients were assessable for this analysis. Twenty-five patients (60%) had tumor reduction by serial imaging. Seventeen patients (40%) underwent surgery (S-CR, n = 14; S-PR, n = 1; and S-UR, n = 2) after a median of 6 months of chemotherapy. With a median postsurgical follow-up of 22 months (range, 13 to 32 months), 11 recurrences have occurred in the 15 S-CR and S-PR patients. Median survival time was 26 months. CONCLUSION: Our data suggest that FOLFOX4 has a high response rate (complete response, partial response, or reduction) in patients with liver-only metastases from colorectal cancer, allowing for successful resection of disease in a portion of patients initially not judged to be optimally resectable. However, a high recurrence rate after surgery was observed, which, in 73% of patients, involved the liver. Further trials are indicated based on the promising results observed in this trial.
