RESUMO
BACKGROUND: Upstaging from DCIS to invasive ductal carcinoma varies widely from 0 to 59%. We aim to identify risk factors associated with upstaging in all DCIS patients and based on specific surgical intervention. METHODS: Patients with a pre-operative diagnosis of DCIS undergoing BCT or mastectomy were reviewed. Multivariable analysis was performed to identify risk factors for upstaging. RESULTS: In total, 623 patients had a preoperative diagnosis of DCIS. Upstaging occurred in 74 patients (12%) overall. There was no difference in upstaging rates between mastectomy and BCT (11% v 14% pâ¯=â¯0.27). Sentinel lymph node biopsy was positive in 4/212 patients (1%). Multivariable analysis revealed suspicion of microinvasion (OR 5.7 95%CI2.2-14.9), surgeon suspicion of invasive disease (OR 2.7, 95% CI 1.2-6.4) and larger size/multicentric/extensive tumor (OR 1.9 95% CI 1.1-3.4) increase risk of upstaging. CONCLUSIONS: Suspicion of microinvasion, surgeon suspicion, and tumor size can be used to help guide the use of sentinel lymph node biopsy. For patients without these high risk characteristics, it is hard to justify the use of concurrent SLN biopsy for patients who undergo BCT.

OBJECTIVE: Enhanced recovery has been utilized to decrease length of stay and cost in bariatric surgery. We have recently focused efforts on pre-operative education with regards to discharge on the first post-operative day. The aim of this study was to determine the effectiveness of pre-operative education on discharge timing and readmission rates. METHODS: A retrospective review was conducted after revising discharge expectation education. Patients undergoing first time bariatric operations were included. Early group education focused on average patient stay of 2 postoperative days. Revised education informed patients they could go home on the first post-operative day. RESULTS: A total of 125 patients met inclusion criteria. Implementation of preoperative education was associated with a decrease in mean LOS and greater percentage of patients discharged on post-operative day one. There was no difference in readmission and complication rates. CONCLUSION: Effective pre-operative education can decrease length of stay in first time laparoscopic bariatric surgery.
