Comparative StudyDiscordance between pathologic and radiologic tumor size on breast MRI may contribute to increased re-excision rates.
Preoperative breast MRI does not decrease re-excision rates in patients who undergo lumpectomy. We evaluated concordance of tumor size on MRI and pathologic size in patients who underwent re-excision of margins after lumpectomy. A retrospective review of patients at the Cedars-Sinai Breast Center who received breast MRI was performed. ⋯ Patients with pure DCIS lesions (n = 9) also had smaller radiologic tumor size compared with pathologic (0.64 vs 2.88 cm; P = 0.039), and this difference trended toward significance in those who underwent re-excision (0.55 vs 3.50 cm; P = 0.059). Discordance between tumor size on MRI and pathologic size may contribute to re-excisions in patients who undergo lumpectomy. The limitations of breast MRI to evaluate the extent of DCIS surrounding many breast cancers, and the impact on re-excision rates, should be further evaluated.

Multicenter Study Comparative StudyUtilization and outcomes of laparoscopic versus open paraesophageal hernia repair.
The optimal operative approach for repair of diaphragmatic hernia remains debated. The aim of this study was to examine the utilization of laparoscopy and compare the outcomes of laparoscopic versus open paraesophageal hernia repair performed at academic centers. Data was obtained from the University HealthSystem Consortium database on 2726 patients who underwent a laparoscopic (n = 2069) or open (n = 657) paraesophageal hernia repair between 2007 and 2010. ⋯ The in-hospital mortality was 0.4 per cent for laparoscopic repair versus 0.0 per cent for open repair. In patients presenting with obstruction or gangrene, utilization of laparoscopic repair was 57 per cent and was similarly associated with improved outcomes compared with open repair. Within the context of academic centers, the current practice of paraesophageal hernia repair is mostly laparoscopy. Compared with open repair, laparoscopic repair was associated with superior perioperative outcomes even in cases presenting with obstruction or gangrene.
