Background: Since 2015 operations performed in the field of endocrine surgery have been entered into the European registry EUROCRINE®. The aim of this analysis was a description of the current healthcare situation for adrenal surgery in a homogeneous healthcare environment corresponding to the German-speaking countries-or to the presence of the working group on surgical endocrinology (CAEK) of the German society for general and visceral surgery (DGAV)-and to assess the adherence to current international treatment guidelines., Methods: An analysis of the preoperative diagnostics, the applied operative techniques and the underlying histological entities was carried out for all operations on adrenal glands in Germany, Switzerland and Austria, which were registered in EUROCRINE® from 2015 to 2019., Results: In the total of 21 participating hospitals from the German-speaking EUROCRINE® countries, 658 operations on adrenal glands were performed. In 90% of cases unilateral adrenalectomy was performed, in 3% bilateral adrenalectomy and in 7% other resection procedures. In 41% the main histological diagnosis was an adrenocortical adenoma. In 15% malignant entities were detected on final histology, including 6% adrenocortical carcinoma (ACC) and 8% metastases to the adrenal glands. 23% of the operations were performed for pheochromocytoma. This entity was primarily resected using minimally invasive approaches (82%), whereas minimally invasive techniques were applied in 28% for ACC and in 66% for metastases to the adrenal glands., Conclusion: Surprisingly, following adrenocortical adenoma and pheochromocytoma, the third most common histological entity was metastasis of different extra-adrenal primary tumors to the adrenal gland. Of the operations for ACC 28% were scheduled for minimally invasive techniques, but conversion to open surgery was necessary in 20%. The analysis revealed discrepancies between treatment reality and international guideline recommendations that raise questions, which will be addressed by an updated version of the EUROCRINE® module for the documentation of adrenal surgery.

Objectives: To assess pancreatic fistula rate and secondary endpoints after pancreatogastrostomy (PG) versus pancreatojejunostomy (PJ) for reconstruction in pancreatoduodenectomy in the setting of a multicenter randomized controlled trial., Background: PJ and PG are established methods for reconstruction in pancreatoduodenectomy. Recent prospective trials suggest superiority of the PG regarding perioperative complications., Methods: A multicenter prospective randomized controlled trial comparing PG with PJ was conducted involving 14 German high-volume academic centers for pancreatic surgery. The primary endpoint was clinically relevant postoperative pancreatic fistula. Secondary endpoints comprised perioperative outcome and pancreatic function and quality of life measured at 6 and 12 months of follow-up., Results: From May 2011 to December 2012, 440 patients were randomized, and 320 were included in the intention-to-treat analysis. There was no significant difference in the rate of grade B/C fistula after PG versus PJ (20% vs 22%, P = 0.617). The overall incidence of grade B/C fistula was 21%, and the in-hospital mortality was 6%. Multivariate analysis of the primary endpoint disclosed soft pancreatic texture (odds ratio: 2.1, P = 0.016) as the only independent risk factor. Compared with PJ, PG was associated with an increased rate of grade A/B bleeding events, perioperative stroke, less enzyme supplementation at 6 months, and improved results in some quality of life parameters., Conclusions: The rate of grade B/C fistula after PG versus PJ was not different. There were more postoperative bleeding events with PG. Perioperative morbidity and mortality of pancreatoduodenectomy seem to be underestimated, even in the high-volume center setting.

Objective: An observation of shortness among the female participants of a regular screening program in multiple endocrine neoplasia type 1 (MEN1) patients has raised the question as to whether shortness represents a phenotype characteristic of the disease., Methods: The body height (cm) of genetically confirmed MEN1 patients at the time of diagnosis was compared with the body height of their unaffected relatives (parents, siblings, and children), the midparental body height, and the body height of the age-matched German population. Univariate analysis of the clinical variables was performed using the t-test, Mann–Whitney U test, and ANOVA as appropriate, and multivariate analysis was performed as a logistic regression analysis. P values <0.05 were considered statistically significant., Results: The mean body height of 22 female MEN1 patients (mean age 33.5 years) was 161 +/- 5 cm and thus significantly lesser than the body heights of their unaffected female relatives (mean 165.5 +/- 7.3 cm, P=0.027) and the age-matched German female population (mean 167 cm, P=0.0001) and mid-parental height (177.5 cm, P<0.0001). The mean body height of 24 male MEN1 patients (mean age 34.8 years) was also lesser (177 +/- 6.5 cm) than the average body height of German males in this age group (180 cm, P=0.031) and tended to be lesser than that of their unaffected male relatives (178.5 +/- 5.8 cm, P=0.0915) and the mid-parental body height (177.5 cm, P=0.124)., Conclusions: Small body height is a yet unrecognized phenotype characteristic of MEN1 patients, especially in women. The mechanisms behind this phenotypical characteristic warrant further investigation.

The quality of medical education is an ongoing challenge due to the continuing changes of the health-care politics and general social conditions. At many German university hospitals the dominating picture is overfilled courses, lack of hands-on practice, reduced patient contact and the dull provision of theoretical, abstract knowledge. The reformed surgical curriculum at the University of Marburg university hospital is used to demonstrate that, in spite of large student numbers, a practice-oriented, small-group training at a high didactic level is possible. The surgical training courses are organized in detail and coordinated. Course contents and structure are media available in print and online versions for both students and teachers and thus fulfill not only transparency needs but also contemporary requirements. The strategy of a practice- and patient-oriented, small-group training is followed strictly in the surgical curriculum. In addition, accompanying tutorial possibilities for individual study in an up-to-date learning center are offered. Here the students have the opportunity to intensify knowledge acquired in previous or future courses with numerous attractive education means. Continuous evaluation of the individual training courses at the end of each semester not only document motivation of the students but also serve to continuously improve the training concepts., (© Georg Thieme Verlag KG Stuttgart · New York.)

Previous small scale studies reported that deleterious BRCA2 and CDKN2a germline mutations contribute to a subset of families with inherited pancreatic cancer. As the prevalence of those mutations in the setting of familial pancreatic cancer is still not well defined for the German population, we evaluated the presence of BRCA2 and CDKN2a germline mutations in a large cohort of familial pancreatic cancer (FPC) families from the German National Case Collection for Familial Pancreatic Cancer (FaPaCa). Fifty-six FPC families with at least two-first-degree relatives with confirmed pancreatic cancer that did not fulfill the criteria of other tumor predisposition syndromes, were analyzed for BRCA2 and CDKN2a germline mutations by DHPLC and/or direct sequencing. No deleterious CDKN2a mutations were identified in our families suggesting that CDKN2a mutations are unlikely to predispose PC in FPC families without melanoma. No deleterious BRCA2 mutations, but 6 unclassified variants, were detected in our FPC collection. Combining the prevalence of deleterious BRCA2 germline mutations from our previous separate study with the data from this study we were able to much more accurately estimate the BRCA2 carrier frequency for FPC families in the German population. A total of two mutations and 6 unclassified variants (mutation range: 2.8-11.4%) were thus identified in 70 German FPC families, indicating that the prevalence of BRCA2 mutations in the German FPC population is less frequent than previously reported.

Objective: Familial pancreatic cancer (FPC) accounts for approximately 3% of all pancreatic cancer (PC) cases. It has been suggested that high-risk individuals (HRIs) should be offered a screening programme., Aim: To evaluate the diagnostic yield of a prospective screening programme in HRIs from families with FPC over a period of 5 years., Methods: HRIs of families with FPC of the National German Familial Pancreatic Cancer Registry (FaPaCa) were counselled and enrolled in a prospective, board-approved PC screening programme. Screening included clinical examination, laboratory tests, endoscopic ultrasound (EUS) and MRI with magnetic resonance cholangiopancreaticography (MRCP) and MR angiography., Results: Between June 2002 and December 2007, 76 HRIs of families with FPC took part in the screening programme with a total of 182 examination visits. Twenty-eight patients revealed abnormalities in EUS (n = 25) and/or MR/MRCP (n = 12). In 7 patients fine needle aspiration cytology was performed. Operative pancreatic explorations were performed in 7 individuals, resulting in limited resections in 6 cases. Histopathological examination of the resected specimens showed serous oligocystic adenomas (n = 3), pancreatic intraepithelial neoplasia 1 (PanIN1) lesions with lobular fibrosis (n = 1), PanIN2 lesions (n = 1) and PanIN1 lesion plus a gastric type intraductal papillary mucinous neoplasm (IPMN) (n = 1)., Conclusions: In FPC an EUS/MR/MRCP-based screening programme leads to the detection of potential precursor lesions of PC. However, the yield of an extensive screening programme is low, especially since the tumourigenic value of low grade PanIN lesions is not yet defined. Taking into account the enormous psychological stress for the tested individual and the high costs, a general PC screening in HRIs is not justified.
