Primary hyperparathyroidism during pregnancy: management by minimally invasive surgery based on ultrasound localization.

BACKGROUND: Primary hyperparathyroidism in pregnancy has the potential to seriously impact the mother and foetus. Management may be difficult because the condition is usually diagnosed during pregnancy necessitating a rapid decision to proceed with surgery. Minimally invasive surgery is appealing due to shorter operative times and lower risk of complications. METHOD: We present a consecutive series of eight women diagnosed with hyperparathyroidism during pregnancy. RESULTS: All eight women were treated successfully by parathyroidectomy during pregnancy with no maternal or foetal complications. Seven of these 8 women were treated with minimally invasive parathyroidectomy based on ultrasound localization. CONCLUSION: Where ultrasound localization is performed by experienced endocrine surgeons, minimally invasive parathyroidectomy is a feasible and safe approach in the pregnant patient with primary hyperparathyroidism.

The impact of reduced working hours on surgical training in Australia and New Zealand.

There is a worldwide trend for reduced working hours for doctors, particularly in the developed western countries. This has been led by the introduction of the European Working Time Directive (EWTD) that has had a significant impact on work patterns and training. Australia currently has a more flexible working environment but this is changing. In New Zealand there is a contract for resident doctors defining a maximum 72 h of rostered work per week.

An academy of surgical educators: sustaining education--enhancing innovation and scholarship.

CONTEXT: The aims of surgical education, training and professional development programmes are to ensure surgeons will provide high quality health care throughout their professional lives. Development and delivery of these programmes requires a mixture of surgeons with a different but complimentary range of competencies in medical education, all eager to facilitate learning and support educational scholarship. METHODS: The Royal Australasian College of Surgeons has undertaken a major review of the challenges, risks and opportunities surrounding the development and delivery of its education and continuing professional development programmes. RESULTS: Conflicting demands on surgeons' time have compromised their availability for educational activities. At the same time, a decline has occurred in the recognition and value of teaching and educational scholarship as a consequence of financial rewards and prestige now coming principally from patient care and biomedical research. New educational methods have been introduced which have added to the complexities involved and the level of commitments required. In response, the College and its surgical specialty partners have established an Academy of Surgical Educators as a resource for the nine specialties of surgery. It will promote high quality patient care by providing expert educational leadership, guidance and advice and through the advancement and application of educational scholarship. CONCLUSION: The establishment of the Academy serves as a powerful symbol of the importance the College places on its core responsibility as an educational body. Working in association with the University Departments of Surgery throughout Australia and New Zealand, the Academy will better equip the College and its partner Specialist Societies and Associations to meet and sustain the increasingly sophisticated requirements involved in higher education.

Sub-specialisation in surgery and the continuing challenge of providing emergency surgery services.

The future viability of general surgery may depend on combining subspecialty elective surgery with full-scope acute practice in both public and private settings.

Oncoplastic breast surgery: a global perspective on practice, availability, and training.

Oncoplastic surgery is the seamless joining of the extirpative and reconstructive aspects of breast surgery that is performed by a single surgeon. A symposium was held at ISW 2007 in Montreal with a prearranged aim to publish an article on the current and historical record of the developing specialty of oncoplastic breast surgery. The presenters and authors are well-known breast surgeons from Australia, Croatia, India, Sweden, and South Africa.

A new surgical education and training programme.

Educating and training tomorrow's surgeons has evolved to become a sophisticated and expensive exercise involving a wide range of learning methods, opportunities and stakeholders. Several factors influence this process, prompting those who provide such programmes to identify these important considerations and develop and implement appropriate responses. The Royal Australasian College of Surgeons embarked on this course of action in 2005, the outcome of which is the new Surgical Education and Training programme with the first intake to be selected in 2007 and commence training in 2008. The new programme is competency based and shorter than any designed previously. Implicitly, it recognizes in the curriculum and assessment development and processes, the nine roles and their underpinning competencies identified as essential for a surgeon. It is an evolution of the previous programme retaining that which has been found to be satisfactory. There will be one episode of selection directly into the candidate's specialty of choice and those accepted will progress in an integrated and seamless fashion, provided they meet the clinical and educational requirements of each year. The curriculum and assessment in the basic sciences include both generic and specially aligned components from the commencement of training in each of the nine surgical specialties. Born of necessity and developed through extensive research, discussion and consensus, the implementation of this programme will involve many challenges, particularly during the transition period. Through cooperation, commitment and partnerships, a more efficient and better outcome will be achieved for trainees, their trainers and their patients.

Total thyroidectomy for amiodarone-associated thyrotoxicosis in patients with severe cardiac disease.

BACKGROUND: Surgical treatment of amiodarone-associated thyrotoxicosis (AAT) is effective although fewer than 100 cases have been reported world wide. MATERIALS AND METHODS: We reviewed 14 patients treated with total thyroidectomy by a single surgeon from 1998 to 2005. RESULTS: There were 11 male and 3 female patients who ranged in age from 26 to 82 years (average 50.5). Nine patients refractory to medical management and 5 in whom amiodarone needed to be continued were treated surgically. Ten patients developed thyrotoxicosis while being treated with amiodarone, but 4 became thyrotoxic after ceasing amiodarone 2, 2, 6 and 13 months previously. One patient recently had a cardiac transplant, and 4 were on the active cardiac transplant waiting list. Cardiac ejection fractions ranged from 15% to 50% (average 39%). Four patients had serious complications from medication used to control thyrotoxicosis, including one case of agranulocytosis from carbimazole. Total thyroidectomy was performed under general anaesthesia with no significant intraoperative complications and no deaths. There were no recurrent laryngeal nerve injuries. Two patients required short-term calcium supplementation. All patients had rapid resolution of their symptoms and were euthyroid on thyroxine postoperatively. Two patients had such improvement they were removed from the cardiac transplant list. CONCLUSIONS: Despite severe cardiac disease, total thyroidectomy can be performed successfully under general anaesthesia. Surgery should be considered early in the treatment plan. Surgery is particularly appropriate where it is considered necessary to continue amiodarone, when there are complications from the medications used to treat thyrotoxicosis and to facilitate fitness for or defer the need for cardiac transplantation.

New era: prophylactic surgery for patients with multiple endocrine neoplasia-2a.

BACKGROUND: The surgical management of patients with multiple endocrine neoplasia-2A (MEN-2A) continues to evolve with specific genotype-phenotype correlations allowing for a more tailored approach. In this study, we report the surgical management of one of the largest MEN-2A families with a rearranged during transfection (RET) codon 804 mutation. METHOD: This is a cohort study comprising all at-risk kindred within a single known MEN-2A family. Prophylactic total thyroidectomy with lymph node dissection was recommended to all mutation carriers aged 5 years and older. RESULTS: There were a total of 48 at-risk individuals in the MEN-2A kindred, with 22 patients undergoing thyroidectomy after appropriate preoperative evaluation. A total of 9 patients had medullary thyroid cancer including 5 with a normal preoperative calcitonin level. A total of 11 patients had C-cell hyperplasia and 7 showed histological evidence of parathyroid disease. Only the index case had a phaeochromocytoma. CONCLUSIONS: Genetic testing for germline mutations in the RET proto-oncogene has allowed precise identification of affected RET carriers and provided the opportunity for prophylactic or 'preclinical' surgery to treat and in fact to prevent medullary thyroid cancer. This concept of prophylactic surgery based on a genetic test is likely to be applied more widely as the tools of molecular biology advance.

Re-operation for hyperparathyroidism.

INTRODUCTION: Re-operation for hyperparathyroidism (HPT) represents a challenge for experienced endocrine surgeons. The present study reviews the technical and pathological factors for failure of initial surgery and identifies strategies to approach re-operative parathyroidectomy. METHODS: Clinical details, operation notes, pathology, localization studies and complications for re-operative cases performed by three surgeons were reviewed. RESULTS: Over a 10-year period there were 40 re-operative cases with a 98% success rate. There were 31 patients with primary HPT, 21 with persistent primary (PP) and 10 with recurrent primary (RP). Multigland disease (MGD) was present in 19 of the 31 (61%) primary HPT cases. The culprit gland was ectopic in 14 cases, at a normal location in 10 and there was regrowth at previously excised sites or remnant disease in 10. There were nine patients with secondary HPT, four with persistent secondary (PS) and five with recurrent secondary (RS). The culprit gland was ectopic in five, at a normal location in four and regrowth at a previously excised site in two. Pre-operative investigations were employed in all cases and the most helpful were sestamibi scan (S) and selective venous sampling (SVS) for parathyroid hormone (PTH) concentration. True positive localizations for S was in 20 of 34 cases (59%), SVS in seven of nine (78%), computed tomography (CT) in seven of 17 (41%) and ultrasound scan (USS) in 10 of 28 (36%). CONCLUSIONS: Re-operative parathyroidectomy can be performed by experienced surgeons with a very high success rate and minimal complications.
