Sternal fracture: a benign entity?

A retrospective review of the Greenville Memorial Hospital trauma registry revealed 70 patients admitted with sternal fractures over a 38-month period. Localized sternal tenderness was present in 68 (97.1%), external signs of contusion/ecchymosis in 33 (47.1%), and dyspnea in 10 (14.3%) patients. The mechanism of injury was motor vehicle crash in 64 (91.4%) patients, with 46 of these restrained. Isolated sternal fractures were present in 34 (48.6%) patients. Only one death occurred. All sternal fractures were managed with analgesia and rest; surgery was required only when indicated for associated injuries. No patient was found to have an aortic injury or clinically significant cardiac dysrhythmia. Conclusions in this study that differ from those in previous studies can possibly be attributed to an evolving mechanism of sternal injury. This retrospective review shows no association between sternal fracture and clinically significant cardiac injury or injury to the thoracic aorta.

Laparoscopic cholecystectomy in pregnancy.

Laparoscopic cholecystectomy has been performed in the United States since 1989 and currently is the procedure of choice for the management of symptomatic cholelithiasis. Its utility in the pregnant patient has been controversial. Concerns have been expressed for a number of potential problems, including trocar injury to uterus and fetus, effect of pneumoperitoneum on both mother and fetus, induction of preterm labor, teratogenic effects on the fetus, and long-term effects on fetal and neonatal development. We describe the Greenville Hospital System experience with laparoscopic cholecystectomy in pregnancy. From 1992 to 1996, eight laparoscopic cholecystectomies were performed in pregnant females, one during the first trimester and seven during the second trimester. Mean maternal age was 23.8 years (range, 18-31). All procedures were performed for recurrent and intractable symptoms with the average length of symptoms 3.5 weeks (range, 2-4 weeks). Two patients were diagnosed preoperatively with gallstone pancreatitis, two had acute cholecystitis, and four patients were felt to have hyperemesis gravidarum before their diagnosis of gallstones. All procedures were performed under general endotracheal anesthesia with CO2 insufflation pressures of 12 mm Hg. Postoperatively, all patients had uneventful recoveries with complete resolution of their symptoms and were discharged home in an average of 3 days (range, 1-7 days). No postoperative complications to mother or fetus were documented. Eight patients have delivered full-term healthy fetuses with no documented neonatal morbidity or mortality. Long-term follow-up of the infants at a mean of 23 months (range, 2.5-47 months) reveals that all eight infants have progressed to normal healthy children. Our experience and the current world literature demonstrate that laparoscopic cholecystectomy in pregnancy can be performed safely and effectively for symptomatic cholelithiasis, especially when symptoms are recurrent and persistent and may endanger fetal and maternal livelihood. The diagnosis of symptomatic cholelithiasis should be considered in the pregnant patient with recurrent episodes of nausea and vomiting.

Leiomyosarcoma of the colon: a second malignant neoplasm after treatment for a Wilms' tumor.

Leiomyosarcoma of the colon is a rare malignancy. We report the case of a 33-year-old woman with a leiomyosarcoma of the colon occurring as an intussusception 30 years after receiving abdominal irradiation for a Wilms' tumor. A review of the prior and current treatment for Wilms' tumor is discussed, as well as the association between second malignancies and abdominal irradiation. Leiomyosarcoma of the colon usually presents in the fifth and sixth decades of life and is more common in men. The most common symptom is pain. Ninety per cent are diagnosed at surgery for treatment of bleeding, perforation, or obstruction. Surgery remains the primary treatment. Leiomyosarcomas of the gastrointestinal tract are radioresistant, and adjuvant chemotherapy has shown no survival benefit. The overall prognosis is poor, with mean 5-year survival of 28 per cent. General surgeons need to be aware of the possibility of second malignant neoplasms after primary treatment of childhood cancers. Proper reporting is essential to study the long-term effects of early treatment of childhood cancers and in predicting the best treatment outcomes for these patients.
