During World War II, failure to treat penetrating colon injuries with diversion could result in court martial. Based on this wartime experience, colostomy for civilian colon wounds became the standard of care for the next 4 decades. Previous work from our institution demonstrated that primary repair was the optimal management for nondestructive colon wounds. Optimal management of destructive wounds requiring resection remains controversial. To address this issue, we performed a study that demonstrated risk factors (pre or intraoperative transfusion requirement of more than 6 units of packed red blood cells, significant comorbid diseases) that were associated with a suture line failure rate of 14%, and of whom 33% died. Based on these outcomes, a clinical pathway for management of destructive colon wounds was developed. The results of the implementation of this pathway are the focus of this report. ⋯ The clinical pathway for destructive colon wound management has improved outcomes as measured by anastomotic leak rates and colon related mortality. The data demonstrated the need for colostomy in the face of shock and comorbidities. Institution of this pathway results in colostomy for only 7% of all colon wounds.

To determine whether delay of the repair of the ruptured thoracic aorta in patients with other major injuries is safe and has a potential positive impact on survival. ⋯ Delayed repair of acute traumatic aortic rupture is safe under appropriate treatment and should be considered in selected patients.

To identify the risk of systemic metastases from T1a and T1b N0 breast cancers in patients treated in an academic center, and to seek factors to identify the patients at greatest risk of such failure. ⋯ The risk of systemic failure from such tumors barely exceeded 1% at 10 years. Unless future studies can identify a subgroup at higher risk, the cognitive changes associated with cytotoxic chemotherapy or the loss of estrogen involved do not appear to have sufficient offsetting benefit to warrant chemotherapy for this group of women.

The aim of this study was to determine if a significant genetic component contributes to the pathogenesis of symptomatic gallstones. ⋯ These data suggest that genetic factors are responsible for at least 30% of symptomatic gallstone disease. However, the true role of heredity in gallstone pathogenesis is probably higher because data based on symptomatic gallbladder disease underestimates the true prevalence in the population.

To examine donor-site complications after omental harvest for the reconstruction of extraperitoneal wounds and defects. ⋯ The omentum can be safely harvested and reliably used to reconstruct a diverse range of extraperitoneal wounds and defects. Donor-site complications can be significant but are usually limited to abdominal wall infection and hernia. Risk factors associated with complications include the use of pedicled flaps, mediastinitis, and pulmonary failure. This low rate of donor-site complications strongly supports the use of the omentum in the reconstruction of complex wounds and defects.
