RESUMO
OBJECTIVE: To assess recurrence according to the type of surgery for primary hyperparathyroidism (pHPT) in multiple endocrine neoplasia type 1 ( MEN1 ) patients and to identify the risk factors for recurrence after the initial surgery. BACKGROUND: In MEN1 patients, pHPT is multiglandular, and the optimal extent of initial parathyroid resection influences the risk of recurrence. METHODS: MEN1 patients who underwent initial surgery for pHPT between 1990 and 2019 were included. Persistence and recurrence rates after less than subtotal parathyroidectomy (LTSP) and subtotal parathyroidectomy (STP) were analyzed. Patients with total parathyroidectomy with reimplantation were excluded. RESULTS: Five hundred seventeen patients underwent their first surgery for pHPT: 178 had LTSP (34.4%) and 339 STP (65.6%). The recurrence rate was significantly higher after LTSP (68.5%) than STP (45%) ( P < 0.001). The median time to recurrence after pHPT surgery was significantly shorter after LTSP than after STP: 4.25 (1.2-7.1) versus 7.2 (3.9-10.1) years ( P < 0.001). A mutation in exon 10 was an independent risk factor of recurrence after STP (odds ratio = 2.19; 95% CI: 1.31; 3.69; P = 0.003). The 5 and 10-year recurrent pHPT probabilities were significantly higher in patients after LTSP with a mutation in exon 10 (37% and 79% vs 30% and 61%; P = 0.016). CONCLUSIONS: Persistence, recurrence of pHPT, and reoperation rate are significantly lower after STP than LTSP in MEN1 patients. Genotype seems to be associated with the recurrence of pHPT. A mutation in exon 10 is an independent risk factor for recurrence after STP, and LTSP may not be recommended when exon 10 is mutated.

OBJECTIVE: To provide a nationwide description of postoperative outcomes and analysis of prognostic factors following adrenalectomy for metastases. SUMMARY BACKGROUND DATA: Adrenal glands are a common site of metastases in many malignancies. Diagnosisof adrenal metastases is on the rise, leading to an increasing number of patient candidates for surgery without consensual management. METHODS: We conducted a population-based study between January 2012 and December 2022 using the French national health data system (SNDS) and the Eurocrine® registry (NCT03410394). The first database exhaustively covers all procedures carried out in France, while the second provides more clinical information on procedures and tumor characteristics, based on the experience of 11 specialized centers. RESULTS: From the SNDS, we extracted 2,515 patients who underwent adrenalectomy for secondary malignancy and 307 from the Eurocrine® database. The most common primary malignancies were lung cancer (n=1,203, 47.8%) and renal cancer (n=555, 22.1%). One-year survival was 84.3% (n=2,120). Thirty-day mortality and morbidity rates were, respectively, 1.3% (n=32) and 29.9% (n=753, including planned ICU stays). Radiotherapy within the year before adrenalectomy was significantly associated with higher 30-day major complication rates (P=0.039). In the Eurocrine® database, the proportion of laparoscopic procedures reached 85.3% without impairing resection completeness (R0: 92.9%). Factors associated with poor overall survival were presence of extra-adrenal metastases (HR=0.64; P=0.031) and incomplete resection (≥R1; HR=0.41; P=0.015). CONCLUSION: The number of patients who can receive local treatment for adrenal metastases is rising, and adrenalectomy is more often minimally invasive and has a low morbidity rate. Subsequent research should evaluate which patients would benefit from adrenal surgery.
RESUMO
INTRODUCTION: Non-functioning pancreatic neuroendocrine tumor (NF-PanNET) ≤ 2 cm can be observed or resected. Surgery remains recommended for NF-PanNET > 2 cm but its extent, enucleation (EN) versus formal resection, remains controversial. METHODS: Multicentric retrospective cohort of sporadic NF-PanNET patients treated with EN. Short and long-term outcomes were compared according to tumor size on imaging ≤ 2 cm vs > 2 cm. RESULTS: 131patients underwent EN for NF-PanNET, including 103 (79.0%) ≤ 2 cm and 28 (21.0%) > 2 cm (extremes, 4-55 mm). Patients' characteristics were comparable, and tumor characteristics only differed in their diameter. Clavien III-IV complications were similar (18.4% vs 17.9%, p= 1.00) with one death in NF-PanNET ≤ 2cm. Grade B/C pancreatic fistula were comparable (16.5% vs 10.7%, p= 0.850). In NF-PanNET > 2cm there were more pT2/3 stage tumors (85.7% vs 21.4%, p<0.001), similar rates of grade G2/3 tumors (25% vs 16.5%, p= 0.408) with a median Ki67 of 2 (IQR: 1-3), and of lymphovascular and perineural invasions. Lymph node picking was done in 46 (35.1%) patients, with a higher median number of harvested lymph nodes in NF-PanNET > 2 cm (4 vs 3, p= 0.01). All were pN0. R0 resection rate (78.6% vs 82.5%, respectively; p= 0.670) was equivalent. Five-year overall (100% vs 99%, p= 0.602) and 10-year disease-free (96% vs 92%, respectively; p= 0.532) survivals were comparable. CONCLUSIONS: EN for selected NF-PanNET > 2 cm carries equivalent morbidity, overall and disease-free survivals compared to those observed with NF-PanNET ≤ 2 cm.
RESUMO
OBJECTIVE: Describe the diagnostic workup and postoperative results for patients treated by adrenalectomy for primary aldosteronism in France from 2010 to 2020. BACKGROUND: Primary aldosteronism (PA) is the underlying cause of hypertension in 6% to 18% of patients. French and international guidelines recommend CT-scan and adrenal vein sampling as part of diagnostic workup to distinguish unilateral PA amenable to surgical treatment from bilateral PA that will require lifelong antialdosterone treatment.Adrenalectomy for unilateral primary aldosteronism has been associated with complete resolution of hypertension (no antihypertensive drugs and normal ambulatory blood pressure) in about one-third of patients and complete biological success in 94% of patients.These results are mainly based on retrospective studies with short follow-up and aggregated patients from various international high-volume centers. METHODS: Here we report results from the French-Speaking Association of Endocrine Surgery (AFCE) using the Eurocrine® Database. RESULTS: Over 11 years, 385 patients from 10 medical centers were eligible for analysis, accounting for >40% of adrenalectomies performed in France for primary aldosteronism over the period.Preoperative workup was consistent with guidelines for 40% of patients. Complete clinical success (CCS) at the last follow-up was achieved in 32% of patients, and complete biological success was not sufficiently assessed.For patients with 2 follow-up visits, clinical results were not persistent at 1 year for one-fifth of patients.Factors associated with CCS on multivariate analysis were body mass index, duration of hypertension, and number of antihypertensive drugs. CONCLUSIONS: These results call for an improvement in thorough preoperative workup and long-term follow-up of patients (clinical and biological) to early manage hypertension and/or PA relapse.

BACKGROUND: The overall natural history, risk of death and surgical burden of patients with multiple endocrine neoplasia type 1 (MEN1) is not well known. METHODS: Patients with MEN1 from a nationwide cohort were included. The survival of patients with MEN1 was compared with that of the general population using simulated controls. The cumulative probabilities of MEN1-specific operations and postoperative mortality were assessed, and surgical sequences were analysed using sunburst charts and Venn diagrams. RESULTS: A total of 1386 patients with MEN1 were included. Life expectancy was significantly reduced in patients with MEN1 compared with simulated controls from the general population, with a lifetime difference of 15 years. Mutations affecting the JunD interaction domain had a significant negative impact on survival. Survival for patients with MEN1 compared with the general population improved over time. The probability of experiencing at least one specific MEN1 operation was above 95 per cent after 75 years, and most patients had surgery at least twice during their lifetime. Time to a 50 per cent risk of MEN1 surgery was 30.5 years for patients born after 1960, compared with 47.9 years for those born before 1960. Sex and mutations affecting the JunD interacting domain had no impact on time to first surgery. There was considerable heterogeneity in surgical sequences, with no specific clinical pathway. CONCLUSION: Life expectancy was significantly lower among patients with MEN1 compared with the general population, and further decreased in patients with mutations affecting the JunD interacting domain. Almost all patients underwent at least one MEN1-specific operation during their lifetime, but there was no standardized sequence of surgery.

INTRODUCTION: The discovery of thyroid nodule can be a source of concern for the patient. Fine-needle aspiration is the gold standard for their evaluation. We establish a new rapid diagnosis procedure for liquid-based fine needle aspiration (LB-FNA) of thyroid nodules. METHODS: Patients were admitted in a day hospital program and a FNA was performed under ultrasound monitoring guidance. The sample followed a dedicated emergency circuit, and the technique was performed within 2 hours. RESULTS: A total of 92 fine needle aspirations were performed between June 2018 and March 2020. Our results showed 21% cases of nondiagnostic, 50% of benign, 21% of atypia of undetermined significance, 2% of follicular neoplasm, 1% of suspicious for malignancy and 5% of malignant. Thanks to these results, 18 patients underwent surgery: 3 benign and 3 nondiagnostic (corresponding to 100% of benign follicular nodules), 2 follicular neoplasm (100% Hürthle cell adenomas), 1 suspicious for malignancy and 3 malignant (100% papillary carcinoma), 6 atypia of undetermined significance (83% of benign lesions, 17% non invasive follicular nodules). CONCLUSION: Rapid diagnosis for thyroid nodules LB-FNA is possible, requiring a specific network involving radiologists, endocrinologists, cytopathologists and surgeons. This is an easy and effective method to improve the quality of patient care.

OBJECTIVE: The aim of this study was to compare the quality of life (mental health) and voice in patients with or without permanent hypoparathyroidism after total thyroidectomy. SUMMARY BACKGROUND DATA: Permanent hypoparathyroidism is an underestimated complication of thyroid surgery owing to suppression of parathormone secretion. Few studies have evaluated the consequences of hypoparathyroidism on quality of life and none has studied its effects on voice. METHODS: The QoL-hypopara study (ClinicalTrial.gov NCT04053647) was a national observational study. Adult thyroidectomized patients were included between January and June 2020. A serum parathormone level <15 pg/mL >6âmonths after surgery defined permanent hypoparathyroidism. Patients answered the MOS-36-item short-form health (SF-36), the Voice Handicap Index (VHI) surveys, and a list of questions regarding their symptoms. RESULTS: A total of 141 patients were included, 45 with permanent hypoparathyroidism. The median period between thyroid surgery and the questionnaire was 6 (Q1-Q3 4-11) and 4 (4-5) years in hypoparathyroid patients and controls respectively. Hypoparathyroid patients presented a reduced median mental score ratio (SF-36) [0.88 (Q1-Q3 0.63-1.01) vs 1.04 (0.82-1.13), P = 0.003] and a lower voice quality (incidence rate ratio for total VHI 1.83-fold higher, P < 0.001). In multivariable analysis, hypoparathyroidism [-0.17 (95% confidence interval -0.28 to -0.07), P = 0.002], but not age, female sex, thyroid cancer, or abnormal TSH level, was associated with the reduced mental score ratio. Myalgia, joint pain, paresthesia, tetany, anxiety attack, and exhaustion were the most common symptoms among hypoparathyroid patients (>50%). CONCLUSIONS: Hypoparathyroid patients present significantly impaired quality of life, lower voice quality, and frequent symptoms. These results reinforce the importance of preventing this complication.

National and international guidelines about thyroid surgery seem to be moving more and more towards less radical surgical procedures but everyday practice does not seem to always align with them. We describe for the first time the role of non-surgical parameters in the surgeon's choice for thyroid surgery. OBJECTIVE: The ain of this study was to describe thyroid surgery and to identify the factors leading to either a total or a partial thyroidectomy regardless of the severity of the thyroid disease. SUMMARY BACKGROUND DATA: National and international guidelines about thyroid surgery seem to be moving more and more toward less radical surgical procedures but everyday practice does not seem to always align with them. METHODS: We based this nationwide retrospective cohort study on a national database that compiles discharge abstracts for every admission for thyroidectomy to French acute healthcare facilities (PMSI database 2010 to 2019). RESULTS: In this study, 375,810 patients (male: 23%; age = 53â±â15 years) had a thyroidectomy (partial: 28%) for cancer (17%), hyperthyroidism (16%), nonfunctioning goiter (64%), or other (3%). We noticed a global trend toward more partial thyroidectomy (P < 0.001) with a significant increase in the proportion of lobectomy in the post-ATA recommendations' period (P < 0.001) as well as in the "French Levothyrox crisis" period, in which we saw an unexpected rise of adverse events notifications associated with the marketing of a new formula of Levothyrox (P < 0.001) amid widespread media coverage. In a multivariate analysis, we also identified that complete resection was more frequently performed in centers with a caseload >40/year [P < 0.001, odds ratio (OR) = 1.48], for obese patients (body mass index >30âkg/m2; P < 0.001, OR = 1.42), and according to the indication of surgery (OR benign = 1, OR cancer = 2.25, OR hyperthyroidism = 4.13). CONCLUSION: We describe for the first time the role of non-surgical parameters in the surgeon's choice for thyroid surgery.

CONTEXT: [18 F]FDG PET/CT improves adrenal tumour characterization. However, there is still no consensus regarding the optimal imaging biomarkers of malignancy. OBJECTIVES: To assess the performance of Tumour standardized uptake value (SUV)max :Liver SUVmax for malignancy-risk and to build and evaluate a prediction model. DESIGN/METHODS: The cohort consisted of consecutive patients with adrenal masses evaluated by [18 F]FDG PET/CT. The gold standard for malignancy was based on histology or a multidisciplinary consensus in nonoperated cases. The performance of the previously reported cut-off for Tumour SUVmax :Liver SUVmax (>1.5) was evaluated in this independent cohort. Additionally, a predictive model of malignancy was built from the training cohort (previous study) and evaluated in the validation cohort (current study). RESULTS: Sixty-four patients were evaluated; 28% of them had a Cushing's syndrome. Fifty-four adrenal masses were classified as benign and 10 as malignant (including 7 adrenocortical carcinomas). Compared to benign masses, malignant lesions were larger in size, had higher unenhanced densities and higher [18 F]FDG uptake. CT-derived anthropometric parameters did not differ between benign and malignant masses. A tumour SUVmax :Liver SUVmax > 1.5 showed a good diagnostic performance: Se = 90.0%/Sp = 92.6%/PPV = 69.2%/NPV = 98.0% and accuracy = 92.2%. A predictive model based on tumour size and tumour-to-liver uptake SUVmax ratio for malignancy-risk was validated and provides a complementary approach to the ratio. CONCLUSIONS: Tumour SUVmax :Liver SUVmax uptake ratio is a useful biomarker for diagnosis of adrenal masses. Another tactic would be to calculate with the model an individual risk of malignancy and integrate this information into a shared decision-making process.

AIM: To assess postoperative complications and control of hormone secretions following pancreatoduodenectomy (PD) performed on multiple endocrine neoplasia type 1 (MEN1) patients with duodenopancreatic neuroendocrine tumors (DP-NETs). BACKGROUND: The use of PD to treat MEN1 remains controversial, and evaluating the right place of PD in MEN1 disease makes sense. METHODS: Thirty-one MEN1 patients from the Groupe d'étude des Tumeurs Endocrines MEN1 cohort who underwent PD for DP-NETs between 1971 and 2013 were included. Early and late postoperative complications, secretory control and overall survival were analyzed. RESULTS: Indication for surgery was: Zollinger-Ellison syndrome (n = 18; 58%), nonfunctioning tumor (n = 9; 29%), insulinoma (n = 2; 7%), VIPoma (n = 1; 3%) and glucagonoma (n = 1; 3%). Mean follow-up was 141 months (range 0-433). Pancreatic fistulas occurred in 5 patients (16.1%), distant metastases in 6 (mean onset of 43 months; range 13-110 months), postoperative diabetes mellitus in 7 (22%), and pancreatic exocrine insufficiency in 6 (19%). Five-year overall survival was 93.3% [CI 75.8-98.3] and ten-year overall survival was 89.1% [CI 69.6-96.4]. After a mean follow-up of 151 months (range 0-433), the biochemical cure rate for MEN-1 related gastrinomas was 61%. CONCLUSION: In MEN1 patients, pancreatoduodenectomy can be used to control hormone secretions (gastrin, glucagon, VIP) and to remove large NETs. PD was found to control gastrin secretions in about 60% of cases.

INTRODUCTION: The cytological diagnosis of follicular-patterned thyroid lesions is challenging, especially since the World Health Organisation classification has recognised non-invasive follicular thyroid neoplasm with papillary-like features. These entities are often classified as indeterminate on cytology. Molecular testing has been proposed to help classify indeterminate nodules. RAS and K601E BRAF mutations are mostly encountered in follicular-patterned lesions, but their diagnostic value is not well established. Nuclear scores have also been proposed to help classify indeterminate lesions. OBJECTIVE: To investigate the correlation between cytological features and histology and to assess nuclear scores in a series of indeterminate RAS or BRAF K601E positive thyroid nodules. METHODS: The cytological parameters of 69 indeterminate RAS or BRAF K601E-positive thyroid nodules were evaluated. The Strickland and Maletta scores and a new nuclear score were assessed. Diagnosis of malignant, benign or indolent neoplasms was confirmed in each case by histology. Malignant and indolent nodules were considered surgical nodules, and adenomas non-surgical nodule. RESULTS: Surgical nodules were associated with the presence of ground glass nuclei (P = .001), grooves (P < .001) or irregular nuclear membranes (P = .01) on cytology. Nuclear scores were more often ≥2 in surgical nodules compared to benign ones (P < .001), with high sensitivity, but a low negative predictive value. CONCLUSIONS: Analysis of nuclear features is useful to distinguish non-surgical from surgical nodules in indeterminate FNAs. Although nuclear scores are not ideal rule-out tests for indeterminate RAS or BRAF K601E positive nodules, they seem useful to screen non-molecular tested or non-mutated indeterminate FNAs. This work shows that meticulous analysis of nuclear features on cytological specimens can be useful to distinguish non-surgical nodules (adenoma) from surgical nodules in indeterminate FNAs. Although nuclear scores are not rule-out tests for indeterminate RAS or BRAF K601E positive nodules, they are useful in screening non-molecular tested or non-mutated indeterminate FNAs for surgery.

Adenomatoid tumors are benign tumors from mesothelial origin, usually occurring in the genital tract. Extragenital locations, especially in the adrenal gland are extremely rare. Here we are reporting two cases of a 28-year-old and 50-year-old men with an adenomatoid tumor of the right adrenal gland. Usual morphological aspects join scattered and microcystic pattern with epithelioid or signet-ring cells. According to the morphological features, main differential diagnoses are adenocarcinoma metastasis, vascular tumors or mesotheliomas. Immunohistochemistry provides precious help to confirm the mesothelial origin thanks to positivity of epithelial markers (CK7, AE1-AE3, CK5/6) coupled to mesothelial markers (D2-40, Calretinin, WT1). On the other hand, there is no loss of BAP1 by immunohistochemistry and usually a surexpression of P16. Adrenal gland adenomatoid tumor is a benign tumor, which can be promoted by iatrogenous or constitutive immunodepression.

We report the case of a hobnail variant of papillary thyroid carcinoma revealed by a cervical mass in a 67 years-old patient. This new entity in the 2017 WHO classification is rare. Histopathological diagnosis is based on four main criteria, present in≥30% of tumor cells: a discohesive tumor, micropapillary structures and loss of cell polarity and hobnail cells. This tumor expresses markers of thyroid differentiation. The most widely described molecular alteration is BRAF V600E mutation associated with other alterations, especially p53 mutations. This reflects the agressivness of this variant. It is important to recognize the hobnail variant of papillary thyroid carcinoma and to specify it in the pathological report because of its more pejorative prognosis, with local invasion, lymph node and distant metastasis, and deacreased survival. No specific management is recommended, but a close follow up seems necessary.

We report two cases of patients presenting myxoid variant of adrenocortical carcinoma (ACC). This very rare variant is characterized by a tumoral proliferation organized in trabeculae, cords or even pseudo-glands within an acellular myxoid materiel stained by Alcian Blue and negative for PAS. Tumor cells have a small to medium size and have little atypia. Their immunohistochemical profil (positivity of Synaptophysin, SF1, Melan A, Vimentin and Inhibin, with a weak or negative pancytokeratin expression) eliminate the main differential diagnoses (metastasis of a myxoid adenocarcinoma and soft tissue myxoid tumor). Many scoring systems have been proposed in order to evaluate the risk of malignancy of these lesions: the Weiss score seems less efficient to evaluate malignancy in this variant than the reticulinic algorithm or the Helsinki score. Prognosis of myxoid variant of ACC seems worse than classical ACC.

OBJECTIVE: The aim of the study was to investigate whether patients who undergo surgery in hospitals experiencing significant length of stay (LOS) reductions over time are exposed to a higher risk of severe adverse events in the postoperative period. SUMMARY BACKGROUND DATA: Surgical care innovation has encouraged hospitals to shorten LOS under financial pressures with uncertain impact on patient outcomes. METHODS: We selected all patients who underwent elective colectomy or urgent hip fracture repair in French hospitals between 2013 and 2016. For each procedure, hospitals were categorized into 3 groups according to variations in their median LOS as follows: major decrease, moderate decrease, and no decrease. These groups were matched using propensity scores based on patients' and hospitals' potential confounders. Potentially avoidable readmission for severe adverse events and death at 6 months were compared between groups using Cox regressions. RESULTS: We considered 98,713 patients in 540 hospitals for colectomy and 206,812 patients in 414 hospitals for hip fracture repair before matching. After colectomy, patient outcomes were not negatively impacted when hospitals reduced their LOS [hazard ratio (95% confidence interval): 0.93 (0.78-1.10)]. After hip fracture repair, patients in hospitals with major decreases in LOS had a higher risk of severe adverse events [1.22 (1.11-1.34)] and death [1.17 (1.04-1.32)]. CONCLUSIONS: Patients who underwent surgical procedures in hospitals experiencing major decreases in LOS were demonstrated worse postoperative outcomes after urgent hip fracture repair and not after elective colectomy. Development of care bundles to enhance recovery after emergency surgeries may allow better control of LOS reduction and patient outcomes.

BACKGROUND: Surgical removal of hyperfunctional parathyroid gland is the definitive treatment for primary hyperparathyroidism (pHPT). Postoperative follow-up shows variability in persistent/recurrent disease rate throughout different centers. OBJECTIVE: To evaluate the incidence of redo surgery after targeted parathyroidectomy for pHPT. METHODS: We performed a nationwide retrospective cohort study on the "Programme de Medicalisation des Systemes d'Information," the French administrative database that collects information on all healthcare facilities' discharges. We extracted data from 2009 to 2018 for all patients who underwent parathyroidectomy for pHPT between January 2011 to December 2016. The primary outcome was the reoperation rate within 2 years since first surgery. Patients who had a first attempt of surgery within the previous 24 months, familial hyperparathyroidism, multiglandular disease, and renal failure were excluded. Results were adjusted according to sex and the Elixhauser Comorbidity Index. Operative volume thresholds to define high-volume centers were achieved by the Chi-Squared Automatic Interaction Detector method. RESULTS: In the study period, 13,247 patients (median age 63, F/M=3.6) had a focused parathyroidectomy by open (88.7%) or endoscopic approach. Need of remedial surgery was 2.8% at 2 years. In multivariate analysis, factors predicting redo surgery were: cardiac history (P=0.008), obesity (P=0.048), endoscopic approach (P=0.005), and low-volume center (P<0.001). We evaluated that an annual caseload of 31 parathyroidectomies was the best threshold to discriminate high-volume centers and carries the lowest morbidity/failure rate. CONCLUSION: Although focused parathyroidectomy represents a standardized operation, cure rate is strongly associated with annual hospital caseload, type of procedure (endoscopic), and patients' features (obesity, cardiac history). Patients with risk factors for redo surgery should be considered for an open surgery in a high-volume center.

OBJECTIVE: To assess the distant metastatic potential of duodeno-pancreatic neuroendocrine tumors (DP-NETs) in patients with MEN1, according to functional status and size. SUMMARY BACKGROUND DATA: DP-NETs, with their numerous lesions and endocrine secretion-related symptoms, continue to be a medical challenge; unfortunately they can become aggressive tumors associated with distant metastasis, shortening survival. The survival of patients with large nonfunctional DP-NETs is known to be poor, but the overall contribution of DP-NETs to metastatic spread is poorly known. METHODS: The study population included patients with DP-NETs diagnosed after 1990 and followed in the MEN1 cohort of the Groupe d'étude des Tumeurs Endocrines (GTE). A multistate Markov piecewise constant intensities model was applied to separate the effects of prognostic factors on 1) metastasis, and 2) metastasis-free death or 3) death after appearance of metastases. RESULTS: Among the 603 patients included, 39 had metastasis at diagnosis of DP-NET, 50 developed metastases during follow-up, and 69 died. The Markov model showed that Zollinger-Ellison-related tumors (regardless of tumor size and thymic tumor pejorative impact), large tumors over 2âcm, and age over 40 years were independently associated with an increased risk of metastases. Men, patients over 40 years old and patients with tumors larger than 2âcm, also had an increased risk of death once metastasis appeared. CONCLUSIONS: DP-NETs of 2âcm in size or more, regardless of the associated secretion, should be removed to prevent metastasis and increase survival. Surgery for gastrinoma remains debatable.

BACKGROUND: Implementation of enhanced recovery after surgery (ERAS) program after pancreatic surgery was associated with decreased length of stay (LOS). However, there were only retrospective uncontrolled before-after study, and care protocols were heterogeneous. We aimed to evaluate the impact of ERAS program on postoperative outcomes after pancreatectomy through a prospective controlled study. METHODS: A before/after study with a contemporary control group was undertaken in patients undergoing pancreatectomy. We compared 2 groups: the intervention hospital that implemented ERAS program and the control hospital that performed traditional care; and 2 periods: the preimplementation and the post-implementation period. A difference-in-differences approach was used to evaluate whether implementation of ERAS program was associated with improved LOS and postoperative morbidity. RESULTS: About 97 and 75 patients were included in intervention and control hospital. In multivariate analysis, implementation of ERAS was associated with a significantly shorten LOS (hazard ratio 1.61; 95% CI 1.07-2.44) and higher compliance rate (OR 1.34; 95% CI 1.18-1.53). Difference-in-differences analysis revealed that LOS, morbidity, and readmission did not differ after ERAS implementation. CONCLUSION: Implementation of ERAS program was safe and effective after pancreatectomy with high compliance rate. LOS was significantly reduced without compromising morbidity.

BACKGROUND: The "practice makes perfect" concept considers the more frequent a hospital performs a procedure, the better the outcome of the procedure. We aimed to study this concept by investigating whether patient outcomes improve in hospitals with a significantly increased volume of high-risk surgery over time and whether a learning effect existed at the individual hospital level. METHODS: We included all patients who underwent one of 10 digestive, cardiovascular and orthopaedic procedures between 2010 and 2014 from the French nationwide hospitals database. For each procedure, we identified three groups of hospitals according to volume trend (increased, decreased, or no change). In-hospital mortality, reoperation, and unplanned hospital readmission within 30 days were compared between groups using Cox regressions, taking into account clustering of patients within hospitals and potential confounders. Individual hospital learning effect was investigated by considering the interaction between hospital groups and procedure year. RESULTS: Over 5 years, 759,928 patients from 694 hospitals were analysed. Patients' mortality in hospitals with procedure volume increase or decrease over time did not clearly differ from those in hospitals with unchanged volume across the studied procedures (e.g., Hazard Ratios [95%] of 1.04 [0.93-1.17] and 1.08 [0.97-1.21] respectively for colectomy). Furthermore, patient outcomes did not improve or deteriorate in hospitals with increased or decreased volume of procedures over time (e.g., 1.01 [0.95-1.08] and 0.99 [0.92-1.05] respectively for colectomy). CONCLUSIONS: Trend in hospital volume over time did not appear to influence patient outcomes based on real-world data. TRIAL REGISTRATION: NCT02788331, June 2, 2016.

OBJECTIVE: To explore the determinants of postoperative outcomes of adrenal surgery in order to build a proposition for healthcare improvement. SUMMARY OF BACKGROUND DATA: Adrenalectomy is the recommended treatment for many benign and malignant adrenal diseases. Postoperative outcomes vary widely in the literature and their determinants remain ill-defined. METHODS: We based this retrospective cohort study on the "Programme de médicalisation des systèmes d'information" (PMSI), a national database that compiles discharge abstracts for every admission to French acute health care facilities. Diagnoses identified during the admission were coded according to the French adaptation of the 10th edition of the International Classification of Diseases (ICD-10). PMSI abstracts for all patients discharged between January 2012 and December 2017 were extracted. We built an Adrenalectomy-risk score (ARS) from logistic regression and calculated operative volume and ARS thresholds defining high-volume centers and high-risk patients with the CHAID method. RESULTS: During the 6-year period of the study, 9820 patients (age: 55â±â14; F/M = 1.1) were operated upon for adrenal disease. The global 90-day mortality rate was 1.5% (n = 147). In multivariate analysis, postoperative mortality was independently associated with age ≥75 years [odds ratio (OR): 5.3; P < 0.001], malignancy (OR: 2.5; P < 0.001), Charlson score ≥2 (OR: 3.6; P < 0.001), open procedure (OR: 3.2; P < 0.001), reoperation (OR: 4.5; P < 0.001), and low hospital caseload (OR: 1.8; P = 0.010). We determined that a caseload of 32âpatients/year was the best threshold to define high-volume centers and 20 ARS points the best threshold to define high-risk patients. CONCLUSION: High-risk patients should be referred to high-volume centers for adrenal surgery.
