RESUMO

BACKGROUND: General surgery residency training has changed with adoption of the 80-hour work week, patient expectations, and the malpractice environment, resulting in decreased resident autonomy during the chief resident year. There is considerable concern that graduating residents are not prepared for independent surgical practice. STUDY DESIGN: Two online surveys were developed, one for "young surgeons" (American College of Surgeons [ACS] Fellows 45 years of age and younger) and one for "older surgeons" (ACS Fellows older than 45 years of age). The surveys were distributed by email to 2,939 young and 9,800 older surgeons. The last question was open-ended with a request to provide comments. A qualitative and quantitative analysis of all comments was performed. RESULTS: The response rate was 9.6% (282 of 2,939) of young and 10% (978 of 9,800) of older surgeons. The majority of young surgeons (94% [58.7% strongly agree, 34.9% agree]) stated they had adequate surgical training and were prepared for transition to the surgery attending role (91% [49.6% strongly agree, 41.1% agree]). In contrast, considerably fewer older surgeons believed that there was adequate surgical training (59% [18.7% strongly agree, 40.2% agree]) or adequate preparation for transition to the surgery attending role (53% [16.93% strongly agree, 36.13% agree]). The 2 groups' responses were significantly different, chi-square test of association (3) = 15.73, p = 0.0012. Older surgeons focused considerably more on residency issues (60% vs 42%, respectively), and young surgeons focused considerably more on business and practice issues (30% vs 14%, respectively). CONCLUSIONS: Young and older surgeons' perceptions of general surgery residents' readiness to practice independently after completion of general surgery residency differ significantly. Future work should focus on determination of specific efforts to improve the transition to independent surgery practice for the general surgery resident.

RESUMO

BACKGROUND: High rates of surgical breast biopsies in community hospitals have been reported but may misrepresent actual practice. METHODS: Patient-level data from 5,757 women who underwent breast biopsies in a large integrated health system were evaluated to determine biopsy types, rates, indications, and diagnoses. RESULTS: Between 2008 and 2010, 6,047 breast biopsies were performed on 5,757 women. Surgical biopsy was the initial diagnostic procedure in 16% (n = 942) of women overall and in 6% (72 of 1,236) of women with newly diagnosed invasive breast cancer. Invasive breast cancer was diagnosed in 72 women (8%) undergoing surgical biopsy compared with 1,164 (24%) undergoing core needle biopsy (P < .001, age adjusted). Main indications for surgical biopsies included symptomatic abnormalities, technical challenges, and patient choice. CONCLUSIONS: Surgical biopsy was the initial diagnostic procedure in 16% of women with breast abnormalities, comparable with rates at academic centers. Rates could be improved by more careful consideration of indications.

RESUMO

Despite numerous advances, lumpectomy remains a challenging procedure. We report on the early use of light-guided lumpectomy. Eight patients with non-palpable breast cancer undergoing lumpectomy for biopsy-proven and radiographically identifiable cancer were enrolled in the study. An optical wire was designed that incorporated a standard hook-wire with an optical fiber. The optical wire was placed in the same manner as a standard hook-wire. During light-guided lumpectomy, an eye-safe laser illuminated the optical wire and created a sphere of light surrounding the cancer. The light was visible at the beginning of each surgery and facilitated approaching the cancer without using the wire. Dissection around the sphere of light kept the wire tip within the surgical specimen. Three of eight initial surgical specimens had focally positive margins. Additional cavity shaves were performed during five lumpectomies and resulted in negative margins in seven of eight patients. Light-guided lumpectomy is a minor change to breast conserving surgery that can be easily incorporated into clinical practice. Further investigation into the clinical benefit of light-guided lumpectomy is warranted.

RESUMO

We describe the development, design, fabrication, and testing of an optical wire to assist in the surgical removal of small lesions during breast-conserving surgery. We modify a standard localization wire by adding a 200-µm optical fiber alongside it; the resulting optical wire fit through an 18 gauge needle for insertion in the breast. The optical wire is anchored in the lesion by a radiologist under ultrasonic and mammographic guidance. At surgery, the tip is illuminated with an eye-safe, red, HeNe laser, and the resulting glowball of light in the breast tissue surrounds the lesion. The surgeon readily visualizes the glowball in the operating room. This glowball provides sufficient feedback to the surgeon that it is used (1) to find the lesion and (2) as a guide during resection. Light-guided lumpectomy is a simple enhancement to traditional wire localization that could improve the current standard of care for surgical treatment of small, nonpalpable breast lesions.

RESUMO

Stereotactic biopsy has proven more cost effective for biopsy of lesions associated with moderately suspicious mammograms. Data regarding selection of stereotactic biopsy (CORE) instead of excisional biopsy (EB) as the first diagnostic procedure in patients with nonpalpable breast lesions and highest suspicion breast imaging-reporting and data system (BI-RADS)-5 mammograms are sparse. Records from a regional health system radiology database were screened for mammograms associated with image-guided biopsy. A total of 182 nonpalpable BI-RADS-5 lesions were sampled in 178 patients over 5 years, using CORE or EB. Initial surgical margins, number of surgeries, time from initial procedure to last related surgical procedure, and hospital and professional charges for related admissions were compared using chi-squared, t-test, and Wilcoxon Mann-Whitney tests. A total of 108 CORE and 74 EB were performed as the first diagnostic procedure. Invasive or in situ carcinoma was diagnosed in 156 (86%) of all biopsies, 95 in CORE and 61 in EB groups. Negative margins of the first surgical procedure were more frequent in CORE (n = 70, 74%) versus EB (n = 17, 28%), p < 0.05. Use of CORE was associated with fewer total surgical procedures per lesion (1.29 +/- 0.05 versus 1.8 +/- 0.05, p < 0.05). Time of initial diagnostic procedure to final treatment did not vary significantly according to group (27 +/- 2 days versus 22 +/- 2 days, CORE versus EB). Mean charges including the diagnostic procedure and all subsequent surgeries were not different between CORE and EB groups ($10,500 +/- 300 versus $11,500 +/- 500, p = 0.08). Use of CORE as the first procedure in patients with highly suspicious mammograms is associated with improved pathologic margins and need for fewer surgical procedures than EB, and should be considered the preferred initial diagnostic approach.
