What is the Outcome of Patients Affected by Intraductal Papillary Mucinous Neoplasms Without High-Risk Stigmata?: A Single-Center Retrospective Study.

OBJECTIVES: The objectives of the study were to define the natural history of intraductal papillary mucinous neoplasms (IPMNs) without high-risk stigmata (HRS) and to identify factors capable of influencing outcome and management. METHODS: This is a retrospective study of patients affected by IPMNs without HRS. Survival analyses included overall survival, disease-specific survival, and years of life lost. Uni- and multivariate analyses were carried out to identify factors capable of predicting years of life lost. RESULTS: Three hundred fifty-six patients were analyzed. Fifty-three patients (14.9%) died: no postoperative mortality, 6 (1.7%) patients from pancreatic cancer and 47 (13.2%) from reasons not related to the disease. Mean overall survival and disease-specific survival were 199.4 (SD, 16.6) and 281 months (SD, 6.9), respectively. The years of life lost of the sample observed with respect to the general population were 2 years and 3 months (15 years and 3 months vs 17 years and 6 months). Younger age, length of follow-up more than 3 years, and surgery significantly increased the years of life lost. CONCLUSIONS: The patients affected by IPMNs without HRS rarely died from the disease. Young age (<65 years) and follow-up more than 3 years seemed to be the only factors capable of influencing the outcome and management.

The Clinical Impact of Splanchnic Ischemia on Patients Affected by Thoracoabdominal Aortic Aneurysms Treated with Fenestrated and Branched Endografts.

BACKGROUND: Fenestrated/branched endografts for aortic repair (FB-EVAR) are valid options to treat thoracoabdominal aortic aneurysms (TAAAs). Successful repair requires manipulation of target visceral vessels (TVVs) with possible splanchnic ischemia. The aim of the study was to evaluate the clinical impact of splanchnic ischemia occurring in FB-EVAR for TAAA. METHODS: Between 2010 and 2015, patients with TAAAs undergoing FB-EVAR were prospectively enrolled. Clinical, morphological, procedural, and 30-day data were evaluated. Splanchnic ischemia was defined as the presence of splanchnic ischemic lesions (SILs) visible at perioperative computed tomography angiography. Preoperative, postoperative, and 30-day hepatic/pancreatic/renal laboratory functions were analyzed. End points were incidence of SILs, laboratory splanchnic functions worsening (≥25% of baseline), and presence of related clinical/morphological and procedural risk factors. RESULTS: Thirty-six patients (male: 78%; age: 73 ± 7 years) with 27 (75%) type I-III and 9 (25%) type IV TAAA who underwent FB-EVAR for a total of 127 TVV (branches: 47-60%; fenestrations: 53-67%). Fourteen SILs occurred in 12 (33%) patients: 4 (29%) in pancreas, 3 (21%) in spleen, 2 (14%) in bowel, 5 (36%) in kidney. The cause was embolic in 79% and thrombotic in 21%. No preoperative clinical/morphological data or procedural data were correlated with SIL. Pancreatic, hepatic, or renal function worsening occurred at 24 hr in 16 (44%), 16 (44%), and 9 (25%) cases, respectively. Overall, SILs were associated with increased values of C-reactive protein (CRP) (17.9 ± 0.4 vs. 9.9 ± 9.0 mg/dL; P = 0.03) and bilirubin (1.2 ± 2.3 vs. 1.0 ± 0.5 mg/dL; P = 0.02) at 24 hr. Specifically, SIL of the celiac trunk and superior mesenteric and renal arteries' parenchyma were associated with the significant laboratory function changes 24 hr. SIL of the superior mesenteric artery was associated with increased 30-day mortality (50% vs. 7 %; P = 0.002). Pancreatic, hepatic, or renal function worsening occurred at 30 days in 2 (6%), 0 (0%), and 4 (12%) cases, with similar laboratory tests in patients with and without SIL. CONCLUSIONS: SIL can be frequently detected after FB-EVAR for TAAA and appears mainly of embolic origin. No clinical, morphological, or procedural predictors could be identified in our series. Postoperative laboratory changes of CRP, bilirubin, activated partial thromboplastin time, and amylases are associated with SIL but disappear without clinical consequences within 30 days. However, SIL occurring in the superior mesenteric artery are associated with an increased 30-day mortality.

An atlas for clinical target volume definition, including elective nodal irradiation in definitive radiotherapy of biliary cancer.

Radiotherapy (RT) is a treatment option for advanced biliary tract cancer (BTC), often combined with sequential and/or concurrent chemotherapy. The use of modern RT techniques requires accurate clinical target volume (CTV) definition and delineation. However, guidelines for CTV delineation in BTC are lacking. Therefore, the aim of this study was to propose a computer tomography (CT) atlas for CTV definition of BTC. We previously proposed guidelines to define the nodal CTV (CTV-N) in BTC. In this study, based on a literature analysis, we defined the margins to be added to the gross tumor volume (GTV; subclinical and microscopic disease) to define the primary tumor CTV (CTV-T). An abdominal contrast enhanced planning CT scan was performed on three different patients with unresectable intrahepatic cholangiocarcinoma (CC), extrahepatic CC and gallbladder cancer. The GTV and anatomical reference structures were outlined on CT images. Then, based on our guidelines, the CTV-T and CTV-N were delineated and merged to define the final CTV in the three patients. An atlas, showing the defined CTV, was generated from the reference CT images to illustrate the CTV for intra-hepatic CC, extra-hepatic CC and gallbladder cancer. This atlas can be used as an aid for CTV definition in patients with BTC treated with modern RT techniques.

Prevalence of Asymptomatic Intraductal Papillary Mucinous Neoplasms in Healthy and Ill Populations Detected by Ultrasonography: A Single-Center Study of 6353 Outpatients.

OBJECTIVES: The aim of this study was to establish the prevalence of intraductal papillary mucinous neoplasms (IPMNs) without and with high-risk stigmata (HRS)/worrisome features (WF) and the epidemiologic association between IPMNs and other diseases. METHODS: Ultrasound examinations of outpatients were evaluated. The IPMN was confirmed by magnetic resonance imaging. The prevalence of IPMNs and HRS/WF IPMNs was calculated. The association between IPMNs and other diseases was studied. RESULTS: The prevalence rate of IPMNs was 3.4%. A total of 1,531,264 IPMNs were expected in Italian population (2.5%), whereas 2257 per 100,000 citizens (2.3%) were expected in the European standard population (ESP2013). The prevalence rates of HRS/WF IPMNs were 0.5%, 0.7%, and 0.6%, in our, the Italian, and the ESP2013 populations, respectively. A total of 432,881 and 620 HRS/WF IPMNs per 100,000 residents were expected in the Italian and the ESP2013 populations, respectively. The IPMN prevalence increased over 50 years of age (odds ratio [OR], 3.2; P < 0.001) and over 70 years of age (OR, 1.9; P < 0.001). Female sex was related to the presence of IPMNs (OR, 1.9; P < 0.001). CONCLUSIONS: Intraductal papillary mucinous neoplasms had a high prevalence in asymptomatic nonhospitalized populations. Age older than 50 years identified a possible risk category.

Organizing pneumonia after pancreatic cancer treatment with nab-paclitaxel and gemcitabine: a case report.

The incidence of pancreatic cancer is increasing. Most patients have advanced disease at diagnosis, and therapeutics is limited in this setting. Gemcitabine and nab-paclitaxel combination is indicated as first-line treatment in patients with metastatic cancer of pancreas. The most common adverse events of Grade 3 or higher gemcitabine and nab-paclitaxel combination are neutropenia, fatigue and neuropathy. In this report, we describe a rare case of organizing pneumonia associated with the use of nab-paclitaxel and gemcitabine in metastatic pancreatic cancer. A 68-year-old female underwent total splenopancreatectomy for ductal adenocarcinoma of the neck of the pancreas, followed by adjuvant chemoradiation therapy. Afterwards she relapsed and received first-line chemotherapy with gemcitabine plus nab-paclitaxel combination for 12 cycles. Following the administration of the 12th cycle of gemcitabine plus nab-paclitaxel, the patient experienced low-grade pyrexia, effort dyspnoea, persistent non-productive cough and malaise. High-resolution CT scan of chest revealed new-onset bilateral peripheral ground-glass opacities, smooth interlobular septal thickening and patchy subpleural consolidation areas, findings consistent with organizing pneumonia. A thorough microbiological workup was negative. Treatment with steroids resulted in prompt clinical and radiological improvement. Organizing pneumonia closely mimics infection or progressive disease and can be difficult to diagnose in the setting of malignancy. Correct diagnosis is of primary importance since delay in treatment can result in significantly adverse patient outcomes.

Prospective validation of a preoperative risk score model based on pancreatic texture to predict postoperative pancreatic fistula after pancreaticoduodenectomy.

BACKGROUND: In 2015, basing on objective preoperative factors related to pancreas remnant texture (body mass index, Wirsung duct size and preoperative diagnosis), we proposed a score model to predict the risk of postoperative pancreatic fistula after partial pancreatectomies. The aim of the present study was to prospectively validate this preoperative predictive risk score for postoperative pancreatic fistula after pancreaticoduodenectomy. METHODS: Prospective study of consecutive patients who underwent pancreaticoduodenectomy in which a preoperative risk score, based on factors related to the pancreatic texture, was calculated. The risk score model was tested by comparison with subjective intraoperative assessment of the pancreas remnant texture and drain amylase value on postoperative day 1. Sensitivity, specificity, positive and negative likelihood ratio and area under the curve were calculated. RESULTS: Eighty-four patients who underwent pancreaticoduodnectomy were analyzed. Clinically relevant pancreatic fistulas rate was 40.6%. The risk score model with a cut-off of 6 increased the odds of pancreatic fistula approximately 3 fold but it was not independently related to it. On the contrary, considering a cut-off of 5, the risk score model increased the odds of pancreatic fistula 11-16 fold and it was independently related to it. The new risk score model and pancreatic texture had high sensitivity (97% and 88%, respectively) and low specificity (34% and 60%, respectively) while the amylase drain value had low sensitivity (44%) and high specificity (92%). CONCLUSIONS: The preoperative risk score model with a cut-off of 5 was a useful predictor of clinically relevant pancreatic fistula after pancreaticoduodenectomy. The drain amylase value represents a complementary factor to the risk score in predicting a pancreatic fistula.

Comparison of Clinical Data and Scores of Quality of Life, Anxiety, and Depression in Patients With Different Types of Intraductal Papillary Mucinous Neoplasms: A Prospective Study.

OBJECTIVES: This study aims to evaluate the well-being of patients with main duct intraductal papillary mucinous neoplasms (MD-IPMNs) or mixed type IPMNs (mixed-IPMNs) of the pancreas. METHODS: Twenty-two patients with MD/mixed-IPMNs of the pancreas were studied, and an equal number of patients having branch duct IPMNs (BD-IPMNs) were used as controls. The short form (SF) -12 Health Survey, State Trait Anxiety Inventory Y-1 and Y-2, General Health Questionnaire, and Beck Depression Inventory II were used to evaluate the quality of life once a year for 2 consecutive years. RESULTS: At basal evaluation, the SF-12 Health Survey questionnaire administered to the 44 patients showed that the values of the physical component and mental component scores were similar between the 2 groups of patients studied. The State Trait Anxiety Inventory Y-1 and Y-2, General Health Questionnaire, and Beck Depression Inventory II scores were also similar in the 2 groups at basal evaluation. No differences were found between MD/mixed-IPMNs and BD-IPMNs at the 1-year and the 2-year evaluations. CONCLUSIONS: The well-being of patients with MD/mixed-IPMNs did not differ as compared with patients with BD-IPMNs.

Active Surveillance Beyond 5 Years Is Required for Presumed Branch-Duct Intraductal Papillary Mucinous Neoplasms Undergoing Non-Operative Management.

OBJECTIVES: To evaluate the results of active surveillance beyond 5 years in patients with branch-duct intraductal papillary mucinous neoplasms (BD-IPMNs) without worrisome features (WF) and high-risk stigmata (HRS) undergoing non-operative management. METHODS: Patients with a minimum follow-up of 5 years who underwent surveillance with at least yearly magnetic resonance imaging were included. New onset of and predictors of WF/HRS during follow-up as well as long-term survival were analyzed. RESULTS: In all, 144 patients were followed for a median of 84 months. At diagnosis multifocal BD-IPMNs were found in 53% of cases and mean size of the largest cyst was 15.5 mm. Changes during follow-up were observed in 69 patients (48%). New onset of WF/HRS were observed in 26 patients (18%) but the rate of HRS was only 4%. WF and HRS developed after a median follow-up of 71 and 77.5 months from diagnosis, respectively, and without previous changes in 19/26 patients. Independent predictors of WF/HRS development were size at diagnosis>15 mm, increase in number of lesions, main pancreatic duct growth rate ≥0.2 mm/year, cyst growth rate >1 mm/year. Overall, the rate of pancreatic invasive malignancy was 2% and the 12-year disease-specific survival was 98.6%. CONCLUSIONS: Long-term nonoperative management is safe for BD-IPMNs without WF and HRS. Discontinuation of surveillance cannot be recommended since one out of six patients developed WF/HRS far beyond 5 years of surveillance and without previous relevant modifications. An intensification of follow-up should be considered after 5 years.

Risk Factors for Malignancy of Branch-Duct Intraductal Papillary Mucinous Neoplasms: A Critical Evaluation of the Fukuoka Guidelines With a Systematic Review and Meta-analysis.

OBJECTIVES: This study aimed to evaluate the accuracy of the risk factors proposed by Fukuoka guidelines in detecting malignancy of branch-duct intraductal papillary mucinous neoplasms. METHOD: Diagnostic meta-analysis of cohort studies. A systematic literature search was conducted using MEDLINE, the Cochrane Library, Scopus, and the ISI-Web of Science databases to identify all studies published up to 2014. RESULTS: Twenty-five studies (2025 patients) were suitable for the meta-analysis. The "high risk stigmata" showed the highest pooled diagnostic odds ratio (jaundice, 6.3; positive citology, 5.5; mural nodules, 4.8) together with 2 "worrisome features" (thickened/enhancing walls, 4.2; duct dilatation, 4.0) and 1 "other parameters" (carbohydrate antigen 19-9 serum levels, 4.6). CONCLUSIONS: An "ideal risk factor" capable of recognizing all malignant branch-duct intraductal papillary mucinous neoplasms was not identified and some "dismal areas" remain. However, "high risk stigmata" were strongly related to malignancy, mainly enhancing mural nodules. Among the "worrisome features," duct dilatation and thickened/enhancing walls were underestimated, and their diagnostic performance was similar to those of "high risk stigmata." The carbohydrate antigen 19-9 serum level should be added to the Fukuoka algorithm because this value could help in carrying out correct management.

Serum tumor markers not useful in screening patients with pancreatic mucinous cystic lesions associated with malignant changes.

BACKGROUND: Serum cancer antigen 19-9 (CA19-9) provides additional information about mucinous cystic pancreatic neoplasm (MPN). This study was undertaken to assess both CA19-9 and carcinoembryonic antigen (CEA) serum concentrations in consecutive patients affected by MPNs and other chronic benign and malignant pancreatic diseases. We also evaluated whether serum CA19-9 and CEA determinations provide additional information such as the presence of invasive carcinoma in MPN patients. METHODS: Serum CA19-9 and CEA from 91 patients with pancreatic diseases were tested by commercially available kits at the time of diagnosis. The upper reference limit of serum CA19-9 was 37 U/mL and that of serum CEA was 3 ng/mL. RESULTS: Thirty-five patients was diagnosed with chronic pancreatitis (CP), 32 with MPN, and 24 with pancreatic ductal adenocarcinoma (PDAC) confirmed histologically. Surgery was carried out in 5 CP patients, in 10 MPN patients (7 of them had severe dysplasia), and in 9 PDAC patients. Serum CA19-9 activity was high in 12 (34.3%) CP patients, in 7 (21.9%) MPN patients, and in 12 (50.0%) PDAC patients (P=0.089). High serum CEA concentrations were noted in 6 (17.1%) CP patients, in 6 (18.8%) MPN patients, and in 12 (50.0%) PDAC patients (P=0.010). In the 7 MPN patients associated with histologically confirmed severe dysplasia, 3 (42.9%) patients had elevated serum activity of serum CA19-9, and 2 (28.6%) patients had high levels of CEA. CONCLUSION: Serum determination of oncological markers is not useful in selecting MPN patients with malignant changes.

Is total pancreatectomy as feasible, safe, efficacious, and cost-effective as pancreaticoduodenectomy? A single center, prospective, observational study.

BACKGROUND: Total pancreatectomy is actually considered a viable option in selected patients even if large comparative studies between partial versus total pancreatectomy are not currently available. Our aim was to evaluate whether total pancreatectomy can be considered as feasible, safe, efficacious, and cost-effective as pancreaticoduodenectomy. METHODS: A single center, prospective, observational trial, regarding postoperative outcomes, long-term results, and cost-effectiveness, in a tertiary referral center was conducted, comparing consecutive patients who underwent elective total pancreatectomy and/or pancreaticoduodenectomy. RESULTS: Seventy-three consecutive elective total pancreatectomies and 184 pancreaticoduodenectomies were compared. There were no significant differences regarding postoperative outcomes and overall survival. The quality of life, evaluated in 119 patients according to the EQ-5D-5L questionnaire, showed that there were no significant differences regarding the five items considered. The mean EQ-5D-5L score was similar in the two procedures (total pancreatectomy = 0.872, range 0.345-1.000; pancreaticoduodenectomy = 0.832, range 0.393-1.000; P = 0.320). The impact of diabetes according to the Problem Areas in Diabetes (PAID) questionnaire did not show any significant differences except for question 13 (total pancreatectomy = 0.60; pancreaticoduodenectomy = 0.19; P = 0.022). The cost-effectiveness analysis suggested that the quality-adjusted life year was not significantly different between the two procedures (total pancreatectomy = 0.910, range 0.345-1.000; pancreaticoduodenectomy = 0.910, range -0.393-1.000; P = 0.320). CONCLUSIONS: From this study, it seems reasonable to suggest that total pancreatectomy can be considered as safe, feasible, and efficacious as PD and acceptable in terms of cost-effectiveness.

Multifocal intraductal papillary mucinous neoplasm of the pancreas from mild dysplasia to invasive carcinoma A case report.

UNLABELLED: Intraductal papillary mucinous neoplasm (IPMN) is defined as an intraductal mucin-producing neoplasm of the pancreatic ducts. IPMNs may be multifocal, have malignant potential and exhibit a broad histological spectrum ranging from adenoma to invasive carcinoma. The "hyperplasia-dysplasia-carcinoma sequence" in the evolution of IPMNs is considered very similar to the "adenoma-carcinoma sequence" of colorectal tumours. Patients with multifocal IPMN are potential candidates to total pancreatectomy, which still carries significant perioperative risks, especially in the elderly. In selected cases a reasonable alternative to total pancreatectomy is represented by the resection of the dominant tumour leaving deliberately in place the smaller, low-risk tumours. In this context, intraoperative ultrasonography (IOUS) can be useful to define the extent of IPMNs and to plan the surgical strategy. We report the case of a 84-year-old female with multiple IPMNs showing different stages of neoplastic progression up to invasive carcinoma. The patient underwent IOUS-guided distal splenopancreatectomy, while the small multiple branchduct type IPMNs of the head of the pancreas were considered at very low risk of neoplastic progression and were deliberately left in place. The patient is alive without recurrence 96 months after surgery and without evidence of progression of the branch-duct type IPMNs of the head of the pancreas. IOUS-guided pancreatectomy should be considered in selected elderly patients affected by multifocal IPMN evolved to invasive carcinoma without evidence of distant metastases. KEY WORDS: Intraductal papillary mucinous neoplasm, Intraoperative ultrasonography, Pancreatectomy.

Implications and issues related to familial pancreatic cancer: a cohort study of hospitalized patients.

BACKGROUND: The surveillance of subjects at risk of pancreatic cancer is restricted to clinical research; the incidence of familial pancreatic cancer needs to be better established. Thus, we aimed to evaluate the frequency of familial pancreatic cancer in a population of hospitalized patients with pancreatic cancer. METHODS: A retrospective study based on the hospital charts of patients discharged with a diagnosis of pancreatic cancer. One hundred and eighty-seven patients or their relatives were called for a phone interview. RESULTS: There were 97 males (51.9 %) and 90 (48.1 %) females. The overall mean ± SD age was 67.3 ± 11.8 years; the age of males was similar to that of females (P = 0140). The mean size of the tumors found was 36.3 ± 17.4 mm (range of 5-110 mm); it was related to gender but was not related to the site of the tumor or the age of the patient. Regarding genetic diseases, three females (1.6 %) had familial adenomatous polyposis; three patients (1 male and two females) (1.6 %) had at least one relative with pancreatic cancer whereas only one 80-year old male patient (0.5 %) had two relatives affected by pancreatic cancer (the mother had died at the 65 years of age and the brother had died at 75 years of age). CONCLUSIONS: The frequency of familial pancreatic ductal adenocarcinoma is small, but its importance, from the point of view of early diagnosis, is not negligible and patients with a risk of familial cancer merit an appropriate clinical follow-up.

Neoadjuvant Chemoradiotherapy and Surgery Versus Surgery Alone in Resectable Pancreatic Cancer: A Single-Center Prospective, Randomized, Controlled Trial Which Failed to Achieve Accrual Targets.

OBJECTIVE: The objective of the study is to evaluate the usefulness of neoadjuvant chemoradiotherapy in resectable pancreatic cancer. METHODS: A single-center RCT of patients affected by resectable pancreatic adenocarcinoma which included arm A (surgery alone) and arm B (neoadjuvant chemoradiation and surgery). The primary endpoint was R0 resection; the secondary endpoints were toxicity; number of patients who completed the neoadjuvant therapy; radiological and pathological response after chemoradiation; and pTNM stage, postoperative morbidity, mortality, and overall and disease-free survival. A sample size of 32 patients was required for each group. RESULTS: The study was terminated early, and 38 patients were randomized: 20 in arm A and 18 in arm B. There was no significant difference regarding R0 resection rate in the two groups (intention-to-treat, OR = 1.91, P = 0.489). Neoadjuvant chemoradiotherapy was completed in 14 out of 18 cases (77.8 %) and the radiological and pathological response was efficacious in 72.3 and 90.9 % of cases, respectively. CONCLUSIONS: Neoadjuvant chemoradiation was feasible, safe, and efficacious, although non-significant results were obtained as a result of the underpowered data due to the difficulty in recruiting patients. Additional multicenter RCTs are needed in the future.

Consensus guidelines on severe acute pancreatitis.

This Position Paper contains clinically oriented guidelines by the Italian Association for the Study of the Pancreas (AISP) for the diagnosis and treatment of severe acute pancreatitis. The statements were formulated by three working groups of experts who searched and analysed the most recent literature; a consensus process was then performed using a modified Delphi procedure. The statements provide recommendations on the most appropriate definition of the complications of severe acute pancreatitis, the diagnostic approach and the timing of conservative as well as interventional endoscopic, radiological and surgical treatments.

Enlarged pancreas: not always a cancer.

Pancreatic fat accumulation has been described with various terms including pancreatic lipomatosis, pancreatic steatosis, fatty replacement, fatty infiltration, fatty pancreas, lipomatous pseudohypertrophy and nonalcoholic fatty pancreas disease. It has been reported to be associated with type 2 diabetes mellitus, acute pancreatitis, pancreatic cancer and the formation of pancreatic fistula. The real incidence of this condition is still unknown. We report a case of pancreatic steatosis in a non-obese female patient initially diagnosed with a mass in the head of the pancreas. Magnetic resonance imaging (MRI) was carried out to define the characteristics of the pancreatic mass. MRI confirmed the diagnosis of fat pancreas. Enlarged pancreas is not always a cancer, but pancreatic steatosis is characterized by pancreatic enlargement. MRI could give a definite diagnosis of pancreatic steatosis or cancer.

Quality of life in patients with long-standing chronic non-pathological pancreatic hyperenzymemia.

BACKGROUND: Chronic non-pathological pancreatic hyperenzymemia is a benign condition characterized by the persistent elevation of serum pancreatic enzymes without morphological alterations of the pancreas. No information is available regarding the quality of life of these subjects. AIM: To evaluate the physical, mental and psychological status of these subjects using SF-12 Health Survey questionnaire and the 12-item General Health Questionnaire. METHODS: Fifty-one consecutive subjects having long-standing chronic non-pathological pancreatic hyperenzymemia (duration: 11.0 years, range 5-21) were studied. The Italian version of the SF-12 questionnaire and the General Health Questionnaire were compiled by the subjects studied. RESULTS: Regarding the SF-12 questionnaire, the physical component scores and the mental component scores were 50.1 ± 8.0 and 44.7 ± 11.7, respectively and these figures were not statistically different from those of reference Italian population. Regarding the psychological status, seven subjects (13.7%) had non-psychotic-psychiatric problems. No statistical differences in the physical component score, mental component score and general health questionnaire were found between patients having non-familial or familial chronic non-pathological pancreatic hyperenzymemia. CONCLUSIONS: Subjects with long-standing chronic non-pathological pancreatic hyperenzymemia had a quality of life no different from that of the Italian population. The explanation provided by the physician regarding the benignity of long-standing chronic non-pathological pancreatic hyperenzymemia is enough to reassure this type of patient.

Branch-type intraductal papillary mucinous neoplasm of the pancreas: clinically and patient-reported outcomes.

OBJECTIVES: The majority of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas are branch duct (BD) IPMNs, and these neoplasms are being diagnosed with increasing frequency; no data are also available on the well-being (quality of life [QoL]) of these patients. We aimed to evaluate the 2-year follow-up results in consecutive patients with BD-IPMNs to assess symptoms at presentation and their morphological progression; the physical and psychological statuses of these patients were also evaluated. METHODS: One hundred one patients with BD-IPMN of the pancreas were enrolled in the study (37.6% men and 62.4% women; mean [SD] age, 66.3 [10.4] years). Magnetic resonance imaging was used to evaluate the modification of the cystic lesions at baseline as well as in the follow-up. The SF-12 Health Survey, the State-Trait Anxiety Inventory Y-1 and Y-2, the 12-Item General Health Questionnaire, as well as the Beck Depression Inventory-II were used to evaluate the QoL once a year. RESULTS: The mean (SD) basal size of the major lesion was 15.5 (8.9) mm, and in the follow-up period, the size remained stable. The QoL did not change during the follow-up period. CONCLUSIONS: Branch duct IPMNs are very slow-growing neoplasms, and they do not affect the QoL of affected patients.

The usefulness of a multidisciplinary team approach in decision making for pancreatic serous cystic neoplasms.

CONTEXT: Serous cystic neoplasms of the pancreas are regarded as benign entities with rare malignant potential and are frequently resected. OBJECTIVE: The purpose of the study was to evaluate the usefulness of a multidisciplinary team (MDT) approach in decision making regarding the diagnosis and management of pancreatic serous cystic neoplasms. METHODS: A retrospective study of a prospective database involving 43 patients with serous cystic neoplasms was carried out. Patients who underwent multidisciplinary team evaluation (Group 1) were compared with patients who did not (Group 2) as regards demographic, clinical, radiological, surgical and pathological data. Uni-multivariate analyses were carried out. RESULTS: Uni-multivariate analysis showed that a multidisciplinary team approach was significantly related to the type of management, suggesting that MDT evaluation independently reduced the odds of surgery (odds ratio (OR) 0.1; 95% confidence interval (CI) 0.02-0.8; P=0.027). Age, second level imaging techniques, latero-lateral diameter, cranio-caudal diameter and Wirsung duct size differed between the two groups; however, the differences were not statistically significant. CONCLUSIONS: A multidisciplinary team approach seems to be useful in proper decision making regarding the diagnosis and management of pancreatic serous cystic neoplasms.

Pancreatic steatosis: Is it related to either obesity or diabetes mellitus?

The accumulation of fat in the pancreatic gland has been referred to using various synonyms, such as pancreatic lipomatosis, fatty replacement, fatty infiltration, fatty pancreas, lipomatous pseudohypertrophy, non-alcoholic fatty pancreatic disease and pancreatic steatosis We believe that pancreatic steatosis is the best description of fat accumulation in the pancreatic gland without fat replacement, and this term also describes the possibility that the fat accumulation is a reversible process. A review of the existing literature was carried out, and it was found that there was notable evidence from both the pathological and the imaging point of view that pancreatic steatosis is an increasing problem due to the increasing incidence of obesity. The conclusion was that pancreatic steatosis was easily detectable using modern imaging techniques, such as ultrasonography, endoscopic ultrasonography, computed tomography and magnetic resonance imaging. Pancreatic steatosis was not due to the presence of diabetes mellitus but was highly associated with the metabolic syndrome. The possible presence of steatopancreatitis should be better evaluated, especially regarding the inflammatory cascade, and additional studies are needed which are capable of assessing whether non-alcoholic steatopancreatitis really exists as does non-alcoholic steatohepatitis. Finally, the presence of exocrine pancreatic function should be extensively evaluated in patients with pancreatic steatosis.
