Adecuate surgical treatment is mandatory in order to achieve cure in patients with breast cancer. Breast surgeons have to choice the best surgical technique over the breast and over the axillary nodes. Two new surgical aproaches have been implemented in the last decade: oncoplastic conservative surgery and sentinel lymph node biopsy. Oncoplastic surgery provides oncologic safety results and good cosmetic outcome. In this paper the technical steps and indications of different oncoplastic techniques in conservative breast surgery are review. Concerning to axillary surgery sentinel lymph node biopsy is the gold standard. However there are several controversial points in sentinel node biopsy referring to indications, identification and histological findings.

En bloc transplantation of the liver, duodenum and pancreas has been successful in humans for the treatment of tumors requiring exenteration of the upper abdomen. We have developed an experimental model in 40 pigs of en bloc transplantation of the liver, duodenum and pancreas. The surgical technique for organ harvesting and preservation has been correct as the early graft function was excellent. We describe in detail the surgical technique in the recipient animal, the anesthetic model and the autopsy findings. Liver function was excellent and endocrine pancreatic function was normal within 8 hours after transplantation. Absorption and insulin-secreting response was normal in a few animals studied with an oral glucose overdose and with the intravenous glucagon test.
