Female surgeons' mentoring experiences and success in an academic career in Switzerland.

PRINCIPLES An increasing proportion of women are working in medicine, although only very few choose surgical specialties and the interest in an academic pursuit is generally smaller among women compared to their male colleagues. The aim of the present study was to analyse factors critical for a successful academic career for female surgeons in Switzerland and to assess the value of mentor-mentee relationships in this context. METHODS An anonymous national survey among board-certified female surgeons and female residents was conducted in Switzerland during spring 2008. The support in career advancement was investigated with five scales: networking, career planning, coaching, role model and emotional support scale. Career development was assessed based on the following criteria: number of talks at scientific conferences, number of peer-reviewed publications, participation in research projects, months of research as a fulltime activity, amount of awarded scholarships, amount of obtained third-party funds and number of research awards obtained. RESULTS In total, 189/318 (59.4%) questionnaires were returned. Mentor-mentee relationships were reported by 109/189 (58%) respondents. The bivariate analysis showed a positive influence on the sum score regarding the respondents who were in a mentor-mentee relationship or who had support in doing household work (p = 0.09). CONCLUSIONS A supporting network, especially in terms of a mentor, is crucial so that female physicians interested in an academic career get the opportunity to accomplish their purpose. There is considerable potential for improvement as almost half of the respondents did not have a mentor in this survey.

Malignant solitary fibrous tumor involving the liver

Solitary fibrous tumors are predominantly benign and are most commonly found in the thoracic cavity and pleura; while reports exist in the literature of malignant solitary fibrous tumors and those located in extrathoracic organs, these cases are considered extremely rare. Herein, a case is reported of a malignant solitary fibrous tumor involving the liver that was diagnosed and treated in a 62-year-old woman. The patient presented with complaints of upper abdominal pain and unintentional weight loss. Computed tomography scan of the abdomen revealed a remarkably large mass, measuring 15 cm × 10 cm × 20 cm, which appeared to be unrelated to any particular organ. The intraoperative finding of a wide communication with the left liver suggested hepatic origin, and served as an indicator for tumor resection via left hemihepatectomy. The diagnosis of solitary fibrous tumor and its malignant nature was confirmed by histological and immunohistochemical examination of the resected tissues. Hepatic solitary fibrous tumor is very rare, and surgery remains the mainstay of treatment. Due to limited reports of such tumors in the literature, little can be said about the benefit of adjuvant therapy and prognosis for the rare cases with malignant histological findings.

Students' interest in becoming a general surgeon before and after a surgical clerkship in German-speaking Switzerland.

PRINCIPLES The proportion of medical graduates entering a surgical career in Switzerland, as well as in most Western countries, is declining. The purpose of the present study was to evaluate the factors influencing medical students when choosing a career in surgery and to identify the impact of a surgical clerkship. METHODS Between February 2007 and July 2007, fifth- to seventh-year medical students at 15 adult surgical departments in German-speaking Switzerland were asked to participate in an anonymous survey. The survey was distributed at the beginning of the clerkship (T1) with a re-evaluation after its conclusion (T2). It included questions concerning career plans, the anticipated conditions at the workplace, lifestyle in residency and as a board-certified physician, and the perception of surgery. RESULTS A total of 185/344 (53.8%) medical students participated in the study. Prolonged working hours during the surgical training period compared to those of other specialties was the only significant predictor for not choosing general surgery as the future field of work (p = 0.02). After the clerkship, medical students rated the possibility of combining professional and personal life, and engaging in a hobby during specialty training in surgery significantly higher (p <0.01 and p = 0.03, respectively). The specialty was named by 33% further students as one of their top three career choices. CONCLUSIONS A surgical clerkship might have a positive impact on the choice of a surgical career. As there might be a shortage of surgeons in the future, lifestyle as the main impediment for choosing a surgical career should be kept in mind.

Women in surgery: a survey in Switzerland

An increasing proportion of women work in medicine; however, only few choose surgical specialties. The objective of this study was to analyze the current situation of female surgeons and surgical residents in Switzerland concerning their personal and professional fulfillment. Of 318 female surgeons and surgical residents included in our study, 189 (59.4%) returned the anonymous questionnaire. Mentor-mentee relationships were mentioned by 110 (58.2%) of the 189 respondents. On the basis of a 7-point Likert scale, these women responded that they were moderately satisfied with their professional (mean score [SD], 2.7 [1.3]) and personal (mean score [SD], 3.0 [1.7]) lives. Of the 189 respondents, 113 (59.8%) mentioned that they felt underappreciated. The most important ways suggested for increasing the attractiveness of a surgical career for women were a reduction in workload (49 respondents [25.9%]), more flexible working hours (38 respondents [20.1%]), and better structured residency programs (23 respondents [12.2%]).

Total Thyroidectomy for Amiodarone-induced Thyrotoxicosis in the Hyperthyroid State

Amiodarone is a potent antiarrhythmic agent, indicated for the treatment of refractory arrhythmias, which may lead to thyrotoxicosis. In these patients, thyroidectomy is a valid therapeutic option. Antithyroid therapy in the immediate preoperative setting and the subsequently accepted minimal delay until thyroidectomy have not been clearly defined yet. The aim of the present study was to show, that total thyroidectomy under general anaesthesia in patients with amiodarone-induced thyrotoxicosis (AIT) is safe without necessarily obtaining an euthyroid state preoperatively.We conducted a retrospective cohort study of prospectively gathered data on 11 patients undergoing total thyroidectomy under general anaesthesia between January 2008 and December 2013 for AIT at our University Hospital.All patients were preoperatively treated with carbimazole, steroids and β-receptor antagonists. Additionally, 3 patients received potassium perchlorate and in one patient carbimazole was changed to propylthiouracil. Plasmapheresis was performed in 3 patients. Only one patient was euthyroid at the time of operation. There were no significant intra- and postoperative complications, especially no signs of thyroid storm. One patient could postoperatively be removed from the cardiac transplant waiting list due to improved cardiac function.Improvements in the interdisciplinary surgical management for AIT between cardiologists, endocrinologists, anaesthetists and endocrine surgeons provide the basis of safe total thyroidectomy under general anaesthesia in hyperthyroid state. Early surgery without long delay for medical antithyroid treatment (with its potential negative side effects) is recommended.

The influence of thiazide intake on calcium and parathyroid hormone levels in patients with primary hyperparathyroidism.

The effects of thiazide medication in patients with primary hyperparathyroidism (PHPT) have so far not been elucidated. The aim of this study was to analyse the extent to which the administration of thiazides may influence biochemical parameters and therefore the diagnosis of PHPT in a large cohort of patients.

Mentoring in general surgery in Switzerland.

Background Mentorship has been found as a key factor for a successful and satisfying career in academic medicine and surgery. The present study was conducted to describe the current situation of mentoring in the surgical community in Switzerland and to evaluate sex differences regarding the impact of mentoring on career success and professional satisfaction. Methods The study was designed as an anonymous national survey to all members of the Swiss Surgical Society in 2011 (820 ordinary and 49 junior members). It was a 25-item questionnaire addressing mentor–mentee relationships and their impact on the professional front. Results Of the 869 mailed surveys, 512 responses were received (response rate: 58.9%). Mentor–mentee relationships were reported by 344 respondents (68.1%) and structured mentoring programs were noted in 23 respondents (6.7%). Compared to individuals without mentors, male mentees exhibited significantly higher subjective career advancement (5.4±1.2 vs. 5.0±1.3; p=0.03) and career development (3.3±1.9 vs. 2.5±1.7; p<0.01) scores, but the differences for female mentees were not statistically significant (4.7±1.1 vs. 4.3±1.2, p=0.16; 2.5±1.6 vs. 1.9±1.4, p=0.26; respectively). The pursuit of an academic career was not influenced by the presence of a mentor–mentee relationship for female (p=0.14) or male participants (p=0.22). Conclusions Mentor–mentee relationships are important for the career advancement of male surgeons. The reason for the lack of an impact on the careers of female surgeons is difficult to ascertain. However, mentoring also provides lifelong learning and personal development. Thus, specific attention should be paid to the development of more structured mentoring programs for both sexes.Background Mentorship has been found as a key factor for a successful and satisfying career in academic medicine and surgery.

Perception of semiquantitative terms in surgery.

Objective:To assess whether semiquantitative terms (eg, “often” or “rare”), which are often used for achieving informed consent, have the same meaning for laypersons and physicians. Background:To obtain informed consent, physicians have to make their patients aware of the risks of an operation. Thereby, semiquantitative terms are often used. Methods:Questionnaire interview among surgeons and randomly approached laypersons. A set of semiquantitative terms was presented to participants for quantification. Pertinent to 8 exemplary complications of common operations, these values were compared among the 2 interviewed groups and corresponding rates in scientific literature. Results:The questionnaire was completed by 48 surgeons and 582 laypersons in Switzerland. Confronted with corresponding complication rates in literature, laypersons underestimated the risk significantly in 6 of 8 cases. After a simulated informed consent conversation with a surgeon by using semiquantitative terms, laypersons overestimated the complication rate significantly in 7 of 8 cases. An interaction analysis did not show any significant difference between correct estimations of complication rates of respondents who graduated, who had a professional medical background or who had had prior contact with the health care system (eg, medical consultation, hospitalization, operation) compared with the others. Conclusions:Laypersons overestimate probabilities of semiquantitative terms named by surgeons. We recommend using “percentages” or “odds ratios” to achieve a more reliable preoperative informed consent.

Different views about work-hour limitations in medicine: a qualitative content analysis of surgeons', lawyers', and pilots' positive and negative arguments.

Background Whereas work-hour regulations have been taken for granted since 1940 in other occupational settings, such as commercial aviation, they have been implemented only recently in medical professions, where they lead to a lively debate. The aim of the present study was to evaluate arguments in favour of and against work-hour limitations in medicine given by Swiss surgeons, lawyers, and pilots. Methods An electronic questionnaire survey with four free-response items addressing the question of what arguments speak in favour of or against work-hour limitations in general and in medicine was sent to a random sample of board-certified surgeons, lawyers in labour law, and pilots from SWISS International Airlines Ltd. Results In all, 279/497 (56%) of the respondents answered the survey: 67/117 surgeons, 92/226 lawyers, and 120/154 pilots. Support for work-hour limitations in general and in medicine was present and higher among lawyers and pilots than it was in surgeons (p<0.001). The latter agreed more with work-hour limitations in general than in medicine (p<0.001). The most often cited arguments in favour of work-hour limitations were “quality and patient safety,” “health and fitness,” and “leisure and work-family balance,” whereas the lack of “flexibility” was the most important argument against. Surgeons expected more often that their “education” and the “quality of their work” would be threatened (p<0.001). Conclusions Work-hour limitations should be supported in medicine also, but a way must be found to reduce problems resulting from discontinuity in patient care and to minimise the work in medicine, which has no education value.

The Surgeon’s Perspective: Promoting and Discouraging Factors for Choosing a Career in Surgery as Perceived by Surgeons

Background The aim of this study was to identify the factors perceived by surgeons that promote surgery as an attractive or unattractive career choice for today’s graduates. In addition, it examined whether the perspectives of surgeons in different professional situations converges. The content of work, contextual work conditions, and calling to this job are discussed in the context of choosing surgery as a career. Methods Eight hundred sixty-nine surgeons were asked to answer open-ended questions regarding the factors that promote surgery as an attractive or unattractive career choice for today’s graduates. Four hundred ninety-two surgeons participated, and 1,525 statements were analyzed using Mayring’s content-analyses method. Chi-square tests were used to analyze the differences among hierarchical positions. Results With respect to the factors that promote surgery as a profession, 40.8% (209/492) of the surgeons stated that surgery is a calling, 29.1% (149/492) of the surgeons provided at least one argument related to the positive task characteristics, and 12.9% (66/492) of the surgeons provided statements related to the positive contextual factors. With respect to the factors that discourage surgery as a profession, 45.7% (234/492) of the surgeons provided at least one argument related to the discouraging work characteristics, and 67.6% (346/492) of the surgeons provided problematic contextual characteristics. Conclusion This study emphasizes the importance of the calling to surgery as an important factor for choosing surgery as a career. However, the extensive workload, training, and poor work-family balance have been identified as factors that discourage graduates from choosing surgery as a career. The identified positive factors could be used to attract and maintain graduates in surgical disciplines.
