RESUMO
BACKGROUND: Outcomes of paediatric thyroid surgery have only been reported in smaller series or over long intervals. The aim of this multicentre study was to describe the recent outcomes of paediatric thyroid surgery in Germany and Austria. METHODS: Patients aged less than or equal to 18 years who underwent thyroid surgery and were prospectively documented in the StuDoQ|Thyroid registry between March 2017 and August 2022 were studied. RESULTS: In total, 604 patients from 90 institutions were included. The mean age was 15.4 years and 75 per cent of patients were female. The most frequent benign pathologies were nodular goitre (35.6 per cent), follicular adenoma (30.1 per cent), and Graves' disease (28.5 per cent). Among 126 thyroid malignancies, papillary thyroid carcinoma was diagnosed in 77.8 per cent of patients, follicular thyroid carcinoma was diagnosed in 10.3 per cent of patients, and medullary thyroid carcinoma was diagnosed in 8.7 per cent of patients. Lymph node metastases were found in 45.9 per cent of patients with papillary thyroid carcinoma and in 36.4 per cent of patients with medullary thyroid carcinoma. Vascular invasion was found in 62.9 per cent of patients with follicular thyroid carcinoma. The mean tumour diameters were 18, 42, and 13 mm in patients with papillary thyroid carcinoma, follicular thyroid carcinoma, and medullary thyroid carcinoma respectively. Early postoperative recurrent laryngeal nerve injury was seen in 27 of 556 patients (4.9 per cent) (22 of 617 (3.6 per cent) nerves at risk with intermittent intraoperative nerve monitoring and 5 of 237 (2.1 per cent) nerves at risk with continuous intraoperative nerve monitoring). Persistent recurrent laryngeal nerve injury was documented in 4 of 556 patients (0.7 per cent). Early postoperative hypoparathyroidism correlated with Graves' disease, thyroid carcinoma, and lymph node dissection. CONCLUSION: Papillary thyroid carcinoma and follicular thyroid carcinoma in children were often advanced at presentation. Persistent or recurrent lymph node metastases were mainly seen in papillary thyroid carcinoma. Overall survival was excellent, but longer follow-up is needed.

The requirements and challenges for the university hospitals in Germany are changing. Especially in surgical subjects, it is more and more difficult to adequately serve these three pillars of university medicine - clinic, research and education. This survey was intended to determine the status quo of general and visceral surgery at universities, in order to provide a basis for proposed solutions.For this online survey, 1505 visceral surgeons at the 38 university clinics were contacted. The questionnaire contained 29 questions on the structure of the clinic, scientific motivation, opportunities for time-off and the appreciation of academic achievements. The type and scope of student courses and the preparation for them were also determined. With regard to patient care, the type and number of services and the course of surgical training were examined. Based on the data published on the websites of the individual clinics on the number, gender, position and academic title of the doctors, a demographic analysis of university visceral surgeons could also be created.Of 1505 surgeons successfully contacted, 352 took part in the survey, which corresponds to a response rate of 23.4%. Of the participants, 93.5% were scientifically active, the majority being in the field of clinical data collection. Many indicated that they were also active in translational and/or experimental research, while educational research was rarely named. 45% confirmed that they could perform scientific work during their normal working hours. The reward for this activity was mostly in the form of time-off for congresses and clinical appreciation. Most participants stated that they were involved in 3-4 student courses per week, with 24.4% reporting that they were not adequately prepared for them.The compatibility of the classic three pillars of clinic, research and teaching continues to be of great relevance. There is a high level of motivation among the participating visceral surgeons not to neglect research and teaching, despite increasing economic pressure in the field of patient care. However, arrangements must be created in order to reward and promote commitment in research and teaching in a structured way.
RESUMO
INTRODUCTION: Surgical risk calculators can estimate risk probabilities for postoperative outcomes utilizing patient-specific risk factors. They provide meaningful information for obtaining informed consent. The aim of the present paper was to evaluate the predictive value of the surgical risk calculators by the American College of Surgeons in German patients undergoing total pancreatectomy. METHODS: Data for patients who underwent total pancreatectomy between 2014 and 2018 were acquired from the Study, Documentation, and Quality Center of the German Society for General and Visceral Surgery. Risk factors were entered manually into the surgical risk calculators and calculated risks were compared with actual outcomes. RESULTS: Of the 408 patients analysed, predicted risk was higher in patients with complications except for the prediction of re-admission (P = 0.127), delayed gastric emptying (P = 0.243), and thrombosis (P = 0.256). In contrast, classification of patients into below, above, or average risk by the surgical risk calculators only produced meaningful results for discharge to nursing facility (P < 0.001), renal failure (P = 0.003), pneumonia (P = 0.001), serious complications, and overall morbidity (both P < 0.001). Assessment of discrimination and calibration showed poor results (scaled Brier scores 8.46 per cent or less). CONCLUSION: Overall surgical risk calculator performance was poor. This finding promotes the development of a specific surgical risk calculator applicable to the German healthcare system.

PURPOSE: The detection of pancreatic cystic lesions (PCL) causes uncertainty for physicians and patients, and international guidelines are based on low evidence. The extent and perioperative risk of resections of PCL in Germany needs comparison with these guidelines to highlight controversies and derive recommendations. METHODS: Clinical data of 1137 patients who underwent surgery for PCL between 2014 and 2019 were retrieved from the German StuDoQ|Pancreas registry. Relevant features for preoperative evaluation and predictive factors for adverse outcomes were statistically identified. RESULTS: Patients with intraductal papillary mucinous neoplasms (IPMN) represented the largest PCL subgroup (N = 689; 60.6%) while other entities (mucinous cystic neoplasms (MCN), serous cystic neoplasms (SCN), neuroendocrine tumors, pseudocysts) were less frequently resected. Symptoms of pancreatitis were associated with IPMN (OR, 1.8; P = 0.012) and pseudocysts (OR, 4.78; P < 0.001), but likewise lowered the likelihood of MCN (OR, 0.49; P = 0.046) and SCN (OR, 0.15, P = 0.002). A total of 639 (57.2%) patients received endoscopic ultrasound before resection, as recommended by guidelines. Malignancy was histologically confirmed in 137 patients (12.0%), while jaundice (OR, 5.1; P < 0.001) and weight loss (OR, 2.0; P = 0.002) were independent predictors. Most resections were performed by open surgery (N = 847, 74.5%), while distal lesions were in majority treated using minimally invasive approaches (P < 0.001). Severe morbidity was 28.4% (N = 323) and 30d mortality was 2.6% (N = 29). Increased age (P = 0.004), higher BMI (P = 0.002), liver cirrhosis (P < 0.001), and esophageal varices (P = 0.002) were independent risk factors for 30d mortality. CONCLUSION: With respect to unclear findings frequently present in PCL, diagnostic means recommended in guidelines should always be considered in the preoperative phase. The therapy of PCL should be decided upon in the light of patient-specific factors, and the surgical strategy needs to be adapted accordingly.

Delayed gastric emptying (DGE) ranks as one of the most frequent complications in pancreatic surgery. It leads to increased costs for healthcare systems, lengthened hospital stays and reduced quality of life. Data about DGE after distal pancreatectomy (DP) are scarce. The StuDoQ|Pancreas registry of the German Society of General and Visceral Surgery provided data of patients who underwent distal pancreatectomy from 1 January 2014 to 31 December 2018. The retrospective evaluation included comprehensive data: 1688 patients were enrolled; DGE occurred 160 times (9.5%); grade "A" was reported for 98 (61.3%), grade "B" for 41 (25.6%) and grade "C" for 21 (13.1%) patients. In univariate analysis pancreatic fistulas were associated with higher frequencies of intraabdominal abscesses (9.1% vs. 2%, p > 0.001), postpancreatectomy haemorrhage (8.1% vs. 3.7%, >0.001) and DGE (14.5% vs. 6%, p < 0.001). According to multivariate analysis, "abscesses with invasive therapy" (p < 0.001), "other surgical complications" (p < 0.001), prolonged "stays in ICU" (p < 0.001), lengthened duration of surgery (p < 0.001) and conventional surgery (p = 0.007) were identified as independent risk factors for DGE. Perioperative and postoperative factors were identified as risk factors for DGE. Following research should examine this highly relevant topic in a prospective, register-based manner. As there is no causal therapy for DGE, its avoidance is of major importance.
RESUMO
OBJECTIVE: The impact of heavier weight of resected thyroid specimen on postoperative morbidity after total thyroidectomy for multinodular benign goiter remains unclear. METHODS: Data from the prospective StuDoQ|Thyroid registry of the German Society of General and Visceral Surgery were analyzed regarding the weight of the resected thyroid specimen and perioperative morbidity (vocal cord palsy, hemorrhage, surgical site infection, and hypocalcemia). To achieve a homogeneous patient population, only patients with total thyroidectomy for multinodular benign goiter were included. RESULTS: A total of 7911 patients from 105 departments underwent total thyroidectomy for benign conditions (January 2017-July 2020). The median resected weight of the thyroid specimen in all patients was 53 g (interquartile range 32-92). In 1732 patients, the specimen weight exceeded 100 g. Intraoperative neuromonitoring was used in 99.5% of patients. Postoperative laryngoscopy revealed vocal cord dysfunction in 480 of 15 822 (3.03%) nerves at risk, with unilateral dysfunction in 454 (2.87%) of patients and bilateral dysfunction in 13 patients (0.08%). In multivariable analysis, a thyroid weight >100 g was an independent predictor of early postoperative vocal cord dysfunction [odds ratio (OR) 1.462, 95% CI 1.108-1.930, Pâ =â 0.007). Heavier (>100 g) thyroid weight was an independent predictor of surgical site infection (OR 1.861, 95% CI 1.203-2.880, Pâ =â 0.005) and also predicted postoperative hemorrhage in the univariate analysis (OR 1.723, 95% CI 1.027-2.889, Pâ =â 0.039). On the contrary, postoperative parathyroid function was not affected. CONCLUSIONS: Heavier (>100 g) resected thyroid weight independently predicts higher postoperative morbidity, including early vocal cord palsy and surgical site infection after total thyroidectomy for benign multinodular goiter.

BACKGROUND: Delayed gastric emptying (DGE) is one of the most common complications after pancreatic head resection. It leads to increased length of hospital stay, high costs for healthcare systems and reduced quality of life. The primary aim of the study was to assess the impact of pylorus preservation, respectively resection on the occurrence of DGE in patients undergoing pancreaticoduodenectomy (PD). METHODS: All cases of pylorus-resecting PD (PRPD) and pylorus-preserving PD (PPPD) entered in the StuDoQ|Pancreas nationwide registry of the German Society of General and Visceral Surgery from 01/01/2014 until 31/12/2018 including demographics, surgical techniques, histopathological and perioperative data were retrospectively analyzed. This study was approved by the ethics committee of the Ruhr-University Bochum, Germany. RESULTS: Data of 5,080 patients were enrolled. PPPD was the method of choice (70.4%). Pylorus preservation had no impact on the occurrence of DGE (20.3% vs. 21.5%, P=0.33), but further risk factors could be identified. The comparison of PPPD and PRPD groups showed statistically significant differences in the surgical approach (primary open approach, 94.8% vs. 98.0%, P<0.001), duration of surgery (326.4 vs. 352.1 minutes, P<0.001), technique of pancreatic anastomosis (pancreaticojejunostomy vs. pancreaticojejunostomy), 78.6% vs. 85.2%, P<0.001). CONCLUSIONS: Patient factors, intraoperative factors, duration of surgery and postoperative factors (postoperative pancreatic fistula, biliary leakage and other surgical complications) were identified as risk factors for DGE. Future research should focus on register-based, prospective, randomised-controlled studies such as the currently recruiting "PyloResPres trial".
RESUMO
AIM: Calcitonin (Ctn) measurement in patients with thyroid disease could potentially increase the detection rates of medullary thyroid carcinoma (MTC) but remains a controversial issue. The aim of this study was to evaluate routine preoperative Ctn measurements. METHODS: All patients with thyroid surgery documented in the prospective StuDoQ|Thyroid registry between March 2017 and September 2020 were included. Cutoff levels for Ctn were determined with receiver-operating characteristic analyses to assess the preoperative diagnosis of MTC in subgroups for females and males. FINDINGS: In 29 590 of 39 679 patients (75%) participating in the registry, routine preoperative Ctn testing was performed. In 357 patients (227 females and 130 males), histopathology confirmed MTC with a mean tumor size of 14.7 mm (±12.43). Biochemical cure was achieved in 71.4% of the patients. Ctn levels between 11 and 20 pg/mL were seen in 2.6% of the patients, and only 0.7% of the patients had Ctn levels above 21 pg/mL. Cutoff levels for the diagnosis of MTC were 7.9 pg/mL for females and 15 pg/mL for males (P < 0.001). The sensitivity and specificity for females were 95 and 98%, and 96 and 97% for males, respectively. CONCLUSION: Routine Ctn testing is a reliable predictor for MTC and provides the opportunity for earlier thyroidectomy before lymph node metastases occur, resulting in a better prognosis. Females with Ctn levels >7.9 pg/mL and males >15 pg/mL without any other extrathyroidal sources for an elevated Ctn should be monitored. Thyroid surgery should be considered if Ctn levels are increasing or ultrasound detects suspicious thyroid lesions.

INTRODUCTION: Partial pancreatoduodenectomy (PD) is the treatment of choice for various benign and malignant tumours of the pancreatic head or the periampullary region. For reconstruction of the gastrointestinal passage, two stomach-preserving PD variants exist: pylorus preservation PD (ppPD) or pylorus resection PD (prPD) with preservation of the stomach. In pancreatic surgery, delayed gastric emptying (DGE) remains a serious complication after PD with an incidence varying between 4.5% and 45%, potentially delaying hospital discharge or further treatment, for example, adjuvant chemotherapy. Evidence is lacking to assess, which variant of PD entails fewer postoperative DGE. METHODS AND ANALYSIS: The protocol of a large-scale, multicentre, pragmatic, two-arm parallel-group, registry-based randomised controlled trial (rRCT) using a two-stage group-sequential design is presented. This patient-blind rRCT aims to demonstrate the superiority of prPD over ppPD with respect to the overall incidence of DGE within 30 days after index surgery in a German real-world setting. A total of 984 adults undergoing elective PD for any indication will be randomised in a 1:1 ratio. Patients will be recruited at about 30 hospitals being members of the StuDoQ|Pancreas registry established by the German Society of General and Visceral Surgery. The postoperative follow-up for each patient will be 30 days. The primary analysis will follow an intention-to-treat approach and applies a binary logistic random intercepts model. Secondary perioperative outcomes include overall severe morbidity (Clavien-Dindo classification), blood loss, 30-day all-cause mortality, postoperative hospital stay and operation time. Complication rates and adverse events will be closely monitored. ETHICS AND DISSEMINATION: This protocol was approved by the leading ethics committee of the Medical Faculty of the Ludwig-Maximilians-Universität, Munich (reference number 19-221). The results will be published in a peer-reviewed journal and presented at international conferences. Study findings will also be disseminated via the website (http://www.dgav.de/studoq/pylorespres/). TRIAL REGISTRATION NUMBER: DRKS-ID: DRKS00018842.

BACKGROUND: Up to 20 per cent of all operations for patients with colorectal cancer (CRC) are performed in octogenarians. Anastomotic leakage is a leading cause of morbidity and death after resection for CRC. The aim of this study was to assess the rate of anastomosis creation, the risk of anastomotic leakage and death in surgery for left-sided CRC in elderly patients. METHODS: This prospective cohort study compared patients less than 80 and 80 or more years with left-sided CRC resection performed between 2013 and 2019. Data were provided from a risk-adjusted surgical quality-assessment system with 219 participating centres in Germany. Outcome measures were the rate of anastomoses, anastomotic leakages, death at 30 days and 2-year overall survival (OS). Propensity score matching was used to control for selection bias and compare subgroups of patients of less than 80 and 80 or more years. RESULTS: Out of 18 959 patients, some 3169 (16.7 per cent) were octogenarians. Octogenarians were less likely to receive anastomoses (82.0 versus 92.9 per cent, P < 0.001; odds ratio 0.50 (95 per cent c.i. 0.44 to 0.58), P < 0.001). The rate of anastomotic leakages did not differ between age groups (8.6 versus 9.7 per cent, P = 0.084), but 30-day mortality rate after leakage was significantly higher in octogenarians (15.8 versus 3.5 per cent, P < 0.001). Overall, anastomotic leakage was the strongest predictor for death (odds ratio 4.95 (95 per cent c.i. 3.66 to 6.66), P < 0.001). In the subgroup with no leakage, octogenarians had a lower 2-year OS rate than younger patients (71 versus 87 per cent, P < 0.001), and in the population with anastomotic leakage, the 2-year OS was 80 per cent in younger and 43 per cent in elderly patients (P < 0.001). After propensity score matching, older age remained predictive for not receiving an anastomosis (odds ratio 0.54 (95 per cent c.i. 0.46 to 0.63), P < 0.001) and for death (odds ratio 2.60 (95 per cent c.i. 1.78 to 3.84), P < 0.001), but not for the occurrence of leakages (odds ratio 0.94 (95 per cent c.i. 0.76 to 1.15), P = 0.524). CONCLUSION: Anastomotic leakage is not more common in octogenarians, but an age of 80 years or older is an independent factor for not receiving an anastomosis in surgery for left-sided CRC. The mortality rate in the case of leakage in octogenarians was reported to exceed 15 per cent.

BACKGROUND: Surgical treatment of Graves' disease (GD) has a potentially increased incidence of postoperative hypoparathyroidism, recurrent laryngeal nerve palsy (RLNP) and bleeding. The aim of this study was to evaluate the current extent of surgery for the treatment of GD and its safety as a short-term outcome. METHODS: Patients who underwent thyroid resection for GD were identified from the prospective StuDoQ/Thyroid registry. Patient data were retrospectively analyzed regarding demographics, surgical procedures and perioperative outcomes. Statistics were performed with Student's t-test or Fisher's exact test and multivariate Cox regression analysis. The level of statistical significance was set at p < 0.05. RESULTS: A total of 1808 patients with GD with a median age of 44 (range 14-85) years were enrolled in a 25-month period by 78 departments, of which 35.7% (n = 645) had an endocrine orbitopathy and 0.1% (n = 6) had thyrotoxic crisis. Conventional open surgery was used in 98.6% of cases and minimally invasive or remote-access approaches were used in 1.4%. Total thyroidectomy was performed in 93.4% of cases (n = 1688). Intraoperative neuromonitoring (IONM) was used in 98.9% (n = 1789) of procedures. In 98.3% (n = 1777) at least one parathyroid gland was visualized and in 20.7% (n = 375) parathyroids were autografted. The rates of unilateral and bilateral transient RLNP were 3.9% (n = 134/3429 nerves at risk) and 0.1% (n = 4/3429 NAR). The rates of transient RLNP tended to be higher when intermittent IONM was used compared to continuous IONM (4.1% vs. 3.4%, p < 0.059). The rate of transient postoperative hypoparathyroidism was overall 29% (n = 525/1808). Multivariate analysis revealed fewer than 300 thyroid resections and fewer than 15 thyroid resections for GD per year, male sex, BMI > 30, autotransplantation of parathyroid glands and previous bilateral thyroid surgery as independent risk factors for postoperative temporary hypoparathyroidism. Reoperations for bleeding (1.3%) were rare. CONCLUSION: Total thyroidectomy with IONM is safe and currently the most common surgical therapy for GD in Germany. Postoperative hypoparathyroidism is the major complication which should be focused on.
RESUMO
BACKGROUND: A number of studies have revealed higher postoperative mortality after operations that were performed toward the end of the week. It is not yet known whether a day-of-the-week effect exists after visceral surgical procedures for cancer in Germany. METHODS: Data on resections of carcinomas of the colon, rectum (2010-2017), and head of the pancreas (2014-2017) (n = 19 703) that had been prospectively acquired by the Study, Documentation, and Quality Center of the German Society for General and Visceral Surgery were analyzed in relation to the day of the week on which the operation was performed. The primary endpoint was postoperative 30-day mortality; the secondary endpoints were complications, length of hospital stay, and MTL30 (a combined outcome criterion that is positive if the patient has died, is still in the hospital, or has been transferred to another acute care hospital 30 days after the index procedure). RESULTS: Resections of colon carcinomas that were performed on Mondays were associated with more advanced tumor stages (T4: 18.4% vs. 15.7%, p <0.001), higher 30-day mortality (3.5% vs. 2.3%, p = 0.004), and a more frequently positive MTL30 (10.5% vs. 8.5%, p = 0.004). Among patients who underwent pancreatic head resections, those whose procedures were on Tuesday had higher mortality (6.2% vs. 3.8%; p = 0.021). Among those who underwent surgery for rectal carcinoma, the day of the week on which the procedure was performed had no effect on postoperative morality. Multivariate analysis revealed that the independent risk factors for postoperative mortality were colonic resection on a Monday (odds ratio [OR]: 1.45; 95% confidence interval [1.11; 1.92], p = 0.008) and pancreatic head resection on a Tuesday (OR: 1.88 [1.18; 2.91], p = 0.006). CONCLUSION: Elective surgery for carcinoma of the colon or pancreatic head is associated with slightly higher mortality if per - formed toward the beginning of the week. On the other hand, the day of the week has no effect on the outcome of surgery for rectal carcinoma.

BACKGROUND: To evaluate the current indications, resection strategies and short-term outcomes of surgery for benign goitre in a country with endemic goitre. METHODS: Data of patients who underwent surgery for benign goitre were retrieved from the prospective StuDoQ/Thyroid registry and retrospectively analysed regarding the patient's demographics, indications for surgery, surgical procedures, histology, and perioperative outcomes. RESULTS: In a 15-month period, 12,888 patients from 83 departments underwent thyroid resections for benign conditions. Main indications for surgery were exclusion of malignancy (68%), compression symptoms (20.7%) and hyperthyroidism (9.7%). Preoperative fine needle aspiration cytology was performed in only 12.2% of patients with the indication "exclusion of malignancy". Thyroidectomy (49.8%) or hemithyroidectomy (36.9%) were performed in 86.7% of patients. Minimally invasive or alternative surgical techniques were applied in only 2.2%. Intraoperative neuromonitoring was used in 98.4% of procedures, in 97.5% of patients at least one parathyroid gland was visualized, and in 15.3% of patients parathyroid tissue was autografted, respectively. The rates of unilateral and bilateral transient recurrent nerve palsy were 3.6% and 0.07% of nerves at risk, the rate of transitory hypoparathyroidism was 15.3%. The rates of postoperative bleeding and wound infections requiring reoperation were 1.4% and 0.07%, respectively. CONCLUSIONS: The indication "exclusion of malignancy" is made too liberally, and there is a strong attitude to perform complete thyroid resections. Postoperative hypoparathyroidism is the major complication after surgery for benign thyroid disease, thus requiring more awareness.
RESUMO
PURPOSE: The purpose of this study is to provide a web-based calculator predicting complication probabilities of patients undergoing colorectal cancer (CRC) surgery in Germany. METHODS: Analyses were based on records of first-time CRC surgery between 2010 and February 2017, documented in the database of the Study, Documentation, and Quality Center (StuDoQ) of the Deutsche Gesellschaft für Allgemein- und Viszeralchirurgie (DGAV), a registry of CRC surgery in hospitals throughout Germany, covering demography, medical history, tumor features, comorbidity, behavioral risk factors, surgical procedures, and outcomes. Using logistic ridge regression, separate models were developed in learning samples of 6729 colon and 4381 rectum cancer patients and evaluated in validation samples of sizes 2407 and 1287. Discrimination was assessed using c statistics. Calibration was examined graphically by plotting observed versus predicted complication probabilities and numerically using Brier scores. RESULTS: We report validation results regarding 15 outcomes such as any major complication, surgical site infection, anastomotic leakage, bladder voiding disturbance after rectal surgery, abdominal wall dehiscence, various internistic complications, 30-day readmission, 30-day reoperation rate, and 30-day mortality. When applied to the validation samples, c statistics ranged between 0.60 for anastomosis leakage and 0.85 for mortality after rectum cancer surgery. Brier scores ranged from 0.003 to 0.127. CONCLUSIONS: While most models showed satisfactory discrimination and calibration, this does not preclude overly optimistic or pessimistic individual predictions. To avoid misinterpretation, one has to understand the basic principles of risk calculation and risk communication. An e-learning tool outlining the appropriate use of the risk calculator is provided.

BACKGROUND: Pancreatic resections are among the most complex procedures in visceral surgery. While mortality has decreased substantially over the past decades, morbidity remains high. The volume-outcome correlation in pancreatic surgery is among the strongest in the field of surgery. The German Society for General and Visceral Surgery (DGAV) established a national registry for quality control, risk assessment and outcomes research in pancreatic surgery in Germany (DGAV SuDoQ|Pancreas). METHODS: Here, we present the aims and scope of the DGAV StuDoQ|Pancreas Registry. A systematic assessment of registry quality is performed based on the recommendations of the German network for outcomes research (DNVF). RESULTS: The registry quality was assessed by consensus criteria of the DNVF in regard to the domains Systematics and Appropriateness, Standardization, Validity of the sampling procedure, Validity of data collection, Validity of statistical analysis and reports, and General demands for registry quality. In summary, DGAV StuDoQ|Pancreas meets most of the criteria of a high-quality clinical registry. CONCLUSION: The DGAV StuDoQ|Pancreas provides a valuable platform for quality assessment, outcomes research as well as randomized registry trials in pancreatic surgery.

BACKGROUND: The recognition of the relevance of sex and gender differences in medicine has significantly increased in the last 20 years. Nonetheless, the implementation of these aspects into clinical practice still remains to be attained. In particular, while sex differences - which refer to biological attributes - are widely accepted, gender concepts - which include sociocultural and psychological properties - are frequently treated with diffidence. METHODS: In December 2012 and January 2013, all members of the German Society for General and Abdominal Surgery (DGAV) were invited to participate in an online-based survey to determine the relevance and incorporation of sex and gender aspects in gastrointestinal medicine and surgery. RESULTS: 493 (13.4%) of the 3,689 members of the DGAV participated in the survey. More than 50% of the participants reported including sex and gender aspects into consultation, diagnosis, and management at least occasionally. However, 44% reported no knowledge of the formal definition of 'gender medicine', suggesting potential differences in the perception of the notion of gender. CONCLUSION: The participants of the survey demonstrated vast knowledge about sex differences, while gender attributes were generally neglected. Since gender features are critically relevant for prevention as well as during medical consultation, we suggest this area as a potential target for further training initiatives.
