Parathyroid autotransplantation during total thyroidectomy. Results of a retrospective study

Authors analyze their experience of parathyroid autotransplantation during total thyroidectomy, with the purpose of seeing whether this practice influenced the rate of postoperative hypocalcemia and/or hypoparathyroidism. We identified three groups of patients: group A, consisting of 57 patients, underwent parathyroid autotransplantation during total thyroidectomy; group B consisting of 87 patients not submitted to intraoperative autotransplantation in whom, as an incidental finding, a parathyroid gland was detected in the surgical specimen; group C consisted of 100 patients who did not undergo autotransplantation and whose surgical specimens were not found to contain parathyroid glands. The three groups were compared for sex and age as well as for a series of clinical and laboratory parameters on the first three postoperative days and at six months after surgery. The rate of permanent hypoparathyroidism was 3.5% in Group A, 3.45% in Group B, and 1% in Group C. Multivariate analysis revealed that all three groups showed postoperative recovery of calcium levels, although the rate and extent of this recovery differed between them. The control group showed a more rapid and more complete recovery of serum calcium values compared with Groups A and B. Calcium recovery in Groups A and B was comparable, in terms of both rate and extent. The same pattern of results emerged for the iPTH values. The analysis of the data showed that there were no significant differences in the analyzed parameters between Groups A and B. This suggests that parathyroid autotransplantation does not influence the rate of postoperative hypocalcemia and/or hypoparathyroidism.

A modified sentinel node and occult lesion localization (SNOLL) technique in non-palpable breast cancer: a pilot study.

BackgroundThe spread of mammographic screening programs has allowed an increasing amount of early breast cancer diagnosis. A modern approach to non-palpable breast lesions requires an accurate intraoperative localization, in order to achieve a complete surgical resection. In addiction, the assessment of lymph node status is mandatory as it represents a major prognostic factor in these patients. The aim of this study is to evaluate the reliability of a modified technical approach using a single nanocolloidal radiotracer to localize both sentinel node and breast occult lesion.MethodsTwenty-five patients with a single non-palpable breast lesions and clinically negative axilla were enrolled. In the same day of surgery, patients underwent intratumoral and peritumoral administration of 99mTc-labeled nanocolloid tracer under sonographic guidance. A lymphoscintigraphy was performed to localize the sentinel lymph node and its cutaneous projection was marked on the skin in order to guide the surgeon to an optimal incision. During surgery an hand-held gamma-detection probe was used to select the best surgical access route and to guide localization of both occult breast lesion and sentinel lymph node. After specimen excision, the surgical field was checked with the gamma-probe to verify the absence of residual sources of significant radioactivity, thereby ensuring a radical treatment in a single surgical session and minimizing normal tissue excision.ResultsBoth targeted breast lesion and sentinel lymph node were localized and removed at the first attempt in every patients and histopathological diagnosis of malignancy was confirmed in 25/26 samples. Non-palpable lesions were included within the surgical margins in all patients and in all samples surgical margins were free from neoplastic infiltration thus avoiding any further reintervention. Only two patients showed metastatic involvement of sentinel lymph node.ConclusionsThe modified sentinel node and occult lesion localization (SNOLL) technique performed with a single injection of nanocolloidal radiotracer has shown an excellent intraoperative identification rate of both non-palpable lesion and sentinel lymph node. This procedure offers, as opposed to standard techniques, an accurate, simple and reliable approach to the management of non-palpable breast cancer.

Oncoplastic central quadrantectomies

Tumors localized in the central quadrant (centrally located breast tumors) have always represented a challenge for the surgeon because of the critical aesthetical matters related to the nipple-areola complex (NAC). Many years of experience with breast cancer patients treated by using various oncoplastic techniques, has allowed us to develop the modified hemibatwing for the treatment of central breast tumors, where the NAC is involved. Modified hemibatwing-along with the removal of the NAC-is a useful oncoplastic technique and it represents an ideal option for the treatment of central tumors because it assures oncological safety, a reduced surgical timetable and greater aesthetical results.

Ostomy in Fecal Incontinence

Although fecal diversion may be considered a failure of fecal incontinence (FI) treatment, it is an effective, safe, and appropriate operation for certain patients with severe incontinence, although aesthetically less preferable [1].
