The purpose of this study was to compare postoperative pain between SF flap and serratus anterior muscle (SM) in direct-to-implant breast reconstruction.
This is a prospective cohort study that included 53 women diagnosed with breast cancer who underwent mastectomy and one-stage implant-based breast reconstruction from January 2020 to March 2021. Twenty-nine patients (54.7%) had SF elevation, and 24 patients (45.3%) underwent SM elevation. We evaluated patient-reported early postoperative pain on the first day after surgery. Also, it was reported that all surgical complications in the first month and patient reported outcomes (PROs) were measured with the BRECON 23 questionnaire.
The serratus fascia group used implants with larger volumes, 407.6 ± 98.9 cc (p < 0.01). There was no significant difference between the fascial and muscular groups regarding the postoperative pain score reported by the patients (2 versus 3; p = 0.30). Also, there was no difference between the groups regarding early surgical complications and PROs after breast reconstruction.
The use of SF seems to cause less morbidity, which makes the technique an alternative to be considered in breast reconstruction. Although there was no statistical difference in postoperative pain scores between the fascia and serratus muscle groups.

PURPOSE: a case-control study comparing two radiocolloids used in scintigraphy to map the sentinel lymph nodes (SLN) in breast cancer patients. METHODS: forty patients were prospectively enrolled between May 2002 and April 2004, after signing an informed consent form. In the present double-blind study, each patient was submitted twice to the same examination, a mammary scintigraphy, one with 99mTc-dextran 500 (dextran) and the other with 99mTc-phytate (phytate), on different days. A volume of 2 ml with 1-1.5 mCi of each radiopharmaceutical, in divided aliquots, was injected in the breast parenchyma in four points around in the tumor and the subcutaneous area superficial to the tumor. The image was obtained 2 h after the injection, using a gamma camera with high-resolution collimator. The lymph nodes were identified by anterior and lateral static scintigraphic images. Statistical analysis was done with the use of McNemar and Z tests. RESULTS: in the analysis of the 40 patients, we had 15 pairs with positive identical images, 4 pairs with negative images and 21 pairs with inconsistent images, either because one of them was negative, or because the SLN numbers were different. When the protocol was opened, we found 35 and 27 positive images and 5 and 13 negative images for dextran and phytate treatment groups, respectively. Among the negative images, 4 were shared by both groups. The McNemar test, used for the statistical analysis, showed p=0.026, odds ratio (OR) = 0.11 with 95% CI 0.01 < OR < 0.85. The accuracy, evaluated by the success ratio of the SLN mapping, was 67.5% for phytate and 87.5% for dextran, with p=0.032. Analysis of variance of the SLN number in lymphoscintigraphy images showed p=0.008. CONCLUSION: these results recommend the use of dextran instead of phytate for the SLN study of breast carcinoma by scintigraphy, when the same methodology is being used.
