The effect of an evidence-based medicine curriculum on breast cancer knowledge and satisfaction of surgical residents.

OBJECTIVE: The current study was performed to determine if evidence-based medicine (EBM) curriculum would affect education of surgical residents. DESIGN: A 5-year prospective study was designed to determine if EBM curriculum could improve residents' satisfaction and understanding of breast cancer management during a breast surgical oncology rotation. During the first 2 years, 45 journal articles were used. During the subsequent 3 years, journal articles were not used. The proportion of patients seen in clinic was collected as an objective measure of the "effort" made by the resident. The final assessment was a 120-question examination. SETTING: Maricopa Medical Center, Phoenix, AZ. Safety net institution with General Surgery residency program. PARTICIPANTS: Postgraduate year 2 general surgery residents. RESULTS: Over 5 years, 30 postgraduate year 2 residents were involved. Univariate analysis showed that female sex (p = 0.04), residents with peer-reviewed publications (p = 0.03), younger age (p = 0.04), American Board of Surgery in-service training examination score (p = 0.01), and clinical effort (p < 0.01) were associated with higher scores. Although residents taught using the journal articles scored 7 points higher on the final examination, this was not significant (p = 0.10). Multivariate analysis showed that American Board of Surgery in-service training examination score and clinic efficiency remained statistically significant. Residents who were taught using the EBM curriculum had significantly higher satisfaction (4.4 vs 3.5, p = 0.001) compared with those who did not go through the EBM curriculum. CONCLUSIONS: The current study demonstrates that an EBM curriculum significantly improved resident satisfaction with the rotation. The EBM curriculum may improve residents' breast cancer knowledge. The most important predictor of resident performance was the effort of resident.

Women's Impression of the Expected Breast Appearance and its Association with Breast Cancer Operations.

BACKGROUND: Significant concern exists from clinicians in all fields that rates of bilateral mastectomy and prophylactic mastectomy are increasing. This study was performed to evaluate women's perception of breast appearance and its association with breast cancer operations. METHODS: From April 2012 to May 2013, all women attending a breast clinic were shown two breast pictures, "natural" and "augmented," and asked which photograph represented the current expected appearance of breasts. Among breast cancer patients, the choice of breast cancer operation was correlated with picture selection. RESULTS: Of 1,177 consecutive women, mean age was 45 years. Overall, 70 % of patients felt that the augmented appearance is expected. This impression was seen in all racial/ethnic groups: non-Hispanic White 65 %, African American 67 %, Hispanic 71 %, and other groups 70 %. Younger age was strongly associated with the augmented appearance (p < 0.0001). Patients older than age 60 years selected the augmented appearance only 51 % of the time. This percentage increased with each younger decade with patients younger than 40 years selecting the augmented appearance in 85 %. Among breast cancer patients, augmented appearance selection was more likely for patients who underwent reconstruction (92 %; p < 0.001), as well as for those undergoing bilateral mastectomy (74 %; p = 0.057) compared with mastectomy alone (49 %). CONCLUSIONS: Most women felt that the augmented appearance of breasts is currently expected, and this impression was more common in young women. This impression may be another factor contributing to the current trend of more extensive breast cancer operations and implant-based reconstructions.

All strictures are not alike: laparoscopic removal of nonadjustable Silastic bands after banded Roux-en-Y gastric bypass.

BACKGROUND: The concept of a nonadjustable Silastic band (NASB) has been used to promote surgically induced weight loss for >30 years. Vertical banded Roux-en-Y gastric bypass is an example. Some patients develop serious, band-related complications requiring treatment. Narrowing at the NASB will lead to refractory nausea, vomiting, regurgitation, and, even, malnutrition, requiring revision of their bariatric operation. We report on the evaluation, diagnosis, and laparoscopic treatment of proximal obstructive symptoms secondary to a NASB. METHODS: From February 2005 to January 2009, we retrospectively reviewed the preoperative and perioperative data for 6 patients who had presented with proximal obstructive symptoms after undergoing banded Roux-en-Y gastric bypass. RESULTS: The mean interval from primary NASB placement to surgery was 58 months (range 25-110). The mean duration of symptoms was 29 months (range 8-70). All patients presented with multiple symptoms, but all had nausea, vomiting, regurgitation, and dysphagia to liquids and solids. The patients had undergone multiple upper endoscopies (mean 4, range 3-6) and dilations (mean 1.3, range 1-2) without relief of their symptoms. All patients underwent successful laparoscopic removal of the NASB. Their mean hospital stay was 1 day (range 0-2). No operative or postoperative complications occurred. The reflux and obstructive symptoms had resolved immediately postoperatively in all patients. CONCLUSION: Patients with a NASB in place can experience proximal obstructive symptoms. Endoscopy is deceptive in judging the stomal size, because the endoscope can be pushed through the band area. Moreover, endoscopic dilation will offer no benefit in most patients with symptomatic banded Roux-en-Y gastric bypass. Laparoscopic removal of the NASB is safe, relieves the symptoms immediately, and can be applied to patients who have undergone both open and laparoscopic Silastic banded bariatric procedures.

A two-decade spectrum of revisional bariatric surgery at a tertiary referral center.

BACKGROUND: Ineffective weight loss or complications of previous bariatric surgery often require revisional bariatric procedures. Our aim was to define the indications, operative approach, and outcomes of revisional bariatric procedures during 2 decades at a tertiary center. METHODS: From our prospective database (n = 1584), including 1985-2004, 218 patients (14%) underwent revisional bariatric procedures. Follow-up (mean 7 yr, range 1 mo to 19 yr) data obtained from patient records and questionnaires were current for 98%. Patients were grouped according to operative indications: group 1, unsatisfactory weight loss (n = 97); group 2, mechanical/symptomatic complications (n = 95); and group 3, severe nutritional/metabolic problems (n = 26). RESULTS: The operative mortality rate was 0.9% (1 case each of pulmonary embolus and cardiac arrest). The serious operative morbidity rate was 26% (wound infection in 13%, leak in 3%, pulmonary embolus in 2%, anemia/hemorrhage in 2%, pneumonia/prolonged ventilation in 2%, and other in 4%). Of the 218 patients, 94% underwent conversion to, or revision of, Roux-en-y gastric bypass. Group 1 achieved substantial weight reduction with a mean body mass index from 51 +/- 1 to 38 +/- 1 kg/m(2), the complications resolved in 88% of group 2, and the nutritional/metabolic problems resolved in 79% of group 3. Patients who underwent revisional surgery 1990 were more likely to present with mechanical/symptomatic/metabolic complications than for unsuccessful weight loss (P <.001). CONCLUSIONS: Revisional bariatric surgery is safe and effective in experienced centers. Complications (mechanical/symptomatic/nutritional) or unsatisfactory weight loss after primary bariatric procedures can be treated effectively with revision to Roux-en-y gastric bypass.

Is Roux-en-Y gastric bypass safe after previous antireflux surgery? Technical feasibility and postoperative symptom assessment.

BACKGROUND: Clinically significant morbid obesity is associated with an increased risk of gastroesophageal reflux disease. Vertical Roux-en-Y gastric bypass (RYGBP) is known to eliminate acid (and bile) in the pouch of cardia, which would provide control of reflux symptoms. The aim of our study was to assess the technical considerations, morbidity, and safety of RYGBP after previous antireflux surgery and evaluate postoperative reflux symptoms. METHODS: Retrospective review of all patients undergoing RYGBP after previous antireflux surgery from three institutions. Follow-up (mean 18 months) data were obtained from medical records and by questionnaire. RESULTS: A total of 19 patients (18 women and 1 man) underwent standard (n = 18) or distal (n = 1) RYGBP 8 +/- 1 years after Nissen (n = 18) or Toupet (n = 1) fundoplication. Open RYGBP was undertaken in 17 of 19 patients. No postoperative deaths occurred. Substantive complications occurred in 4 patients (21%) and included hemorrhage requiring transfusion, concomitant splenectomy, and reoperation for suspected leak in 2. Of the 19 patients, 16 returned the questionnaire, 15 of whom reported subjective improvement in reflux symptoms after RYGBP compared with after antireflux surgery. No patient in this series required medical therapy for reflux symptoms at the last follow-up visit. The body mass index decreased from 42 +/- 2 kg/m(2) to 32 +/- 2 kg/m(2) (mean +/- SEM); all patients with >or=1 year of follow-up had a body mass index of
