RESUMO

The treatment of early breast cancer using oncoplastic breast surgery (OBS) has been gradually increasing in popularity and is recognized for its efficacy in local control and excellent cosmetic results. We herein report a useful technique for obtaining symmetry of the breast shape for an early breast lesion located in an outer area, close to the nipple-areola, in a Japanese patient with ptotic, fatty breasts. We designed two equilateral triangles: one just upon the resected area and the other on the axilla. They were located on a straight line, with one top pointed to the cranial side and one to the caudal side. A crescent area around the areola was de-epithelialized in the 12 o'clock and 6 o'clock directions. Columnar-shaped breast tissue and an equilateral triangular skin flap and fatty tissue were removed together. To fill the defect, a skin-glandular flap was slid horizontally after suturing the inframammary line. Although an incision scar was formed on the breast and lateral chest wall in a Z-shape, this new technique was able to achieve not only cancer control but also excellent cosmetic results.

RESUMO

The treatment of early breast cancer using breast conservation therapy (BCT) commonly ensures local control and acceptable cosmetic results. We herein report a useful technique for obtaining symmetry of the breast shape and a level inframammary line and nipple-areola that achieved excellent results. Four Japanese patients with early breast cancer located on the upper inner area of the breast were enrolled into this study. De-epithelialized skin close to the resected area and skin from the epigastric area with subdermal fatty tissue were moved to repair the defect. Oncoplastic breast surgery (OBS) combining partial mastectomy with the V-rotation mammoplasty technique was useful for patients with breast cancer on the upper inner area of minimal ptotic breasts.

RESUMO

The treatment of early breast cancer using breast conservation therapy (BCT) commonly ensures local control and acceptable cosmetic results. We herein report a useful technique to obtain symmetry of the breast shape and a level inframammary line and nipple-areola, which achieved excellent results. Six Japanese patients with early breast cancer located on the upper area of the breast were enrolled into this study. A triangle-shaped area of skin was removed together with cancerous and healthy-surrounding breast tissue. Two crescents were designed and de-epithelialized in the directions of 9 o'clock and 3 o'clock. The width of the crescent was decided to be the same as a half or the length of the base of a triangle to be removed. After partial mastectomy, the inner and outer glandular flaps were horizontally sutured. The operations were simple to perform and were not associated with any postoperative complications. Oncoplastic breast surgery combining partial mastectomy with triangular skin resection and re-centralization of the nipple-areola was useful for patients with breast cancer on the upper quadrant area of non-ptotic breasts.

RESUMO

BACKGROUND/PURPOSE: This study aimed to evaluate the feasibility and safety of a novel pancreaticogastrostomy technique for diminishing pancreatic fistulas after pancreaticoduodenectomy using gastric wrapping of the pancreatic stump with a twin square-shaped horizontal mattress and a suture fixing the main pancreatic duct to the gastric mucosa anastomosis [twin square wrapping (TSW) method]. METHODS: Fifty-three patients undergoing pancreaticogastrostomy after pancreaticoduodenectomy were included in the study and chronologically divided into a conventional group (n = 32) and a TSW group (n = 21). The perioperative factors and the postoperative outcomes were retrospectively analyzed. RESULTS: The operating time for the pancreatic anastomosis, the total operating time, and the blood loss volume in the TSW group were lower than in the conventional group, but without a statistically significant difference. The TSW group had a significantly lower postoperative white blood cell count and C-reactive protein level, with a reduced intra-abdominal fluid accumulation as assessed by computed tomography on postoperative day 7, had a lower incidence of postoperative complications and pancreatic fistulas, and achieved a shorter duration of drain placement and shorter postoperative hospital stays as compared to the conventional group. CONCLUSIONS: The TSW technique should be considered for reducing pancreatic fistulas by diminishing the postoperative inflammatory response and improving patient outcomes without increasing the operating time.

RESUMO

BACKGROUND: The treatment of early breast cancer using breast conservation therapy (BCT) commonly ensures local control and acceptable cosmetic results. We report a useful technique including the use of a thoracodorsal adipofascial cutaneous flap for reconstructing defects in the outer quadrant area after partial mastectomy, which achieved excellent results. METHODS: During the past 15 years, some modifications have been added to the original method at a rate of one modification every 2-5 years. We classified these modifications into the original method and four modified methods. Modification I: addition of a crescent-shaped dermis on the distant edge of the thoracodorsal adipofascial flap (TDAFF), Modification II: addition of a crescent-shaped dermis on the proximal edge of the TDAFF, Modification III: addition of inframammary formation plus Modification II, and Modification IV: change of a crescent-shaped dermis to a Benz-shaped (shaped like the Mercedes Benz logo) one plus Modification III. We compared the plastic period, postoperative complications, oncological results, and cosmetic results among the original and four modified groups. RESULTS: The patient number was 26, 9, 15, 23, and 10 in the original and Modification I, II, III, and IV groups, respectively. The median observation period was 115, 92, 67, 51, and 32 months, respectively. Postoperative complications were seen in 5 (19%), 0, 2 (13%), 1 (5%), and 0 patients, respectively. Local recurrence was seen in 3 (12%), 0, 0, 0, and 0 patients, respectively. Distant recurrence was seen in 1 (4%), 1 (11%), 3 (20%), 0, and 0 patients, respectively. Cosmetic results evaluated as good-excellent were seen in 19 (73%), 5 (56%), 11 (73%), 19 (83%), and 10 (100%) patients, respectively. CONCLUSIONS: Oncoplastic surgery using an immediate volume replacement technique with a thoracodorsal adipofascial flap was improved by adding some modifications.

RESUMO

BACKGROUND: Sex-determining region Y-box 9 (SOX9) is an important transcription factor for the development and differentiation of cells and their organization. In the present study, the clinical significance of SOX9 expression in oesophageal squamous cell carcinoma was examined. MATERIALS AND METHODS: SOX9 expression in surgical specimens of primary tumours were immunohistochemically investigated in 175 patients with oesophageal squamous cell carcinomas. RESULTS: SOX9 was expressed (moderately or strongly) in 62.9% of samples. Expression of SOX9 was significantly positively correlated with depth of invasion, advanced stage, lymphatic and venous invasion, and poor prognosis. Univariate analysis showed that depth of invasion, lymph node metastasis, distant metastasis, stage, lymphatic invasion, venous invasion, and SOX9 expression were prognostic factors. Multivariate analysis indicated that depth of invasion and stage were independent prognostic factors, but SOX9 expression was not. CONCLUSION: SOX9 expression is related to prognosis in patients with oesophageal squamous cell carcinoma, although it is not an independent prognostic factor.
