BACKGROUND: The SARS-CoV-2 pandemic has had a huge impact on healthcare systems, resulting in many routine diagnostic procedures either being halted or postponed. AIMS: To evaluate whether the diagnoses of colorectal, gastric and pancreatic cancers have been impacted by the SARS-CoV-2 pandemic in Italy. METHODS: A survey designed to collect the number of histologically-proven diagnoses of the three cancers in gastroenterology services across Italy from January 1 to October 31 in 2017-2020. Non-parametric ANOVA for repeated measurements was applied to compare distributions by years and macro-areas. RESULTS: Compared to 2019, in 2020 gastric cancer diagnoses decreased by 15.9%, CRC by 11.9% and pancreatic by 9.9%. CRC distributions showed significant differences between all years, stomach cancer between 2018 and 2020 and 2019-2020, and pancreatic cancer only between 2017 and 2019. The 2019-2020 comparison showed fewer CRC diagnoses in the North (-13.7%), Center (-16.5%) and South (-4.1%), fewer stomach cancers in the North (-19.0%) and South (-9.4%), and fewer pancreatic cancers in the North (-14.1%) and Center (-4.7%), with an increase in the South (+12.3%). Distributions of CRC and gastric cancer were significantly different between all years in the North. CONCLUSIONS: This survey highlights the concerning effects of the COVID-19 pandemic on the diagnostic yield of gastroenterology services for stomach, colorectal and pancreatic cancers in Italy.

OBJECTIVE: The present research aimed to propose a severity grading criterion for bile leakage in pediatric patients after Roux-en-Y hepaticojejunostomy for choledochal cysts. SUMMARY BACKGROUND DATA: Despite a bile leakage classification system from the International Study Group of Liver Surgery (ISGLS) has been developed, a commonly used grading system for pediatric patients after Roux-en-Y hepaticojejunostomy has not yet been established. METHODS: A review of clinical, laboratory, and ultrasonographic parameters were used to develop a grading system for classifying the severity of bile leakage. A total of 267 patients with bile leakage were retrospectively assessed to review the system. RESULTS: We developed a grading system for bile leakage severity for use in pediatric patients following Roux-en-Y hepaticojejunostomy. By applying the criteria to 267 patients, grade I, II, or III bile leakage was determined in 103 patients (8.7%), 115 patients (9.8%), and 49 patients (4.2%) patients, respectively. The most severe bile leakage grade (grade III), was associated with significantly higher γ-glutamyl transpeptidase and amylase levels, greater drain fluid output, more intensive care unit (ICU) admissions, and longer postoperative hospital stay. Interestingly, patients with grade II leakage who underwent reoperation had significantly more ICU admissions, longer postoperative hospital stays (p < 0.05), and higher overall hospitalization cost (p < 0.05) compared with those who underwent conservation management. Of the patients with bile duct stricture and common bile duct (CBD) stones, there were no differences among the different grades of postoperative bile leakage. CONCLUSIONS: The proposed bile leakage criteria may optimize objective diagnosis and therapeutic modalities.

Routine pathologic examination of specimens is a common practice with ill-defined value. The present study is the first to investigate the incidence and cost of incidental microscopic lesions in both haemorrhoidectomy and stapled haemorrhoidopexy specimens. Pathological reports of specimens obtained from haemorrhoidectomy and stapled haemorrhoidopexy procedures performed from January 2003 to May 2017 were analysed. Specimens resulting from patients treated for any disease other than haemorrhoids alone were excluded from the study. Unexpected diagnoses in the pathological report were defined as incidental diagnoses. A cost analysis was then performed. In the considered period we performed a total of 3017 procedures complying with our criteria. We found 65 (2.15%) unexpected lesions. Of the incidental diagnosis, 30 (0.99%) altered either the follow-up or the treatment. The incidences of both findings were extremely higher in haemorrhoidectomies specimens (p < 0.0001). We estimated that the cost of 14 years of routine pathological examination of haemorrhoids specimens was 133,351.4 euros, each consequential incidental diagnosis costing 4445.03 euros. The incidence of unexpected lesions in routine pathologic examination of haemorrhoidectomy and haemorrhoidopexy specimens is low but not negligible. The vast majority of incidental findings were found among haemorrhoidectomy specimens. Even though the real value of routine pathological examination of haemorrhoids specimens is still uncertain, from a clinical standpoint we were glad to suggest each patients the best follow-up and/or treatment. Future studies should assess preoperative patient's risk stratification and careful intraoperative macroscopic inspection strategies for selective pathology examination of haemorrhoids specimens.

BACKGROUND: Most bariatric treatments employ gastric volume reduction. However, there has been no appropriate tool that could assess the anatomical factors of the stomach, and few studies have investigated proper stomach measurement for bariatric treatment. Thus, this study aimed to objectively estimate the individual stomach using three-dimensional (3D) computed tomography (CT) gastrography for the possible acquisition of information that could facilitate bariatric treatment and to validate these factors. METHODS: A total of 100 consecutive patients with different degrees of obesity who underwent 3D CT gastrography were enrolled. Using semiautomatic and manual segmentation tools, 3D volume-rendered images were constructed, and the total volume of the distended stomach, abdominal diameter, and abdominal fat volume (visceral and subcutaneous fat) were measured. Data on patients' baseline characteristics and laboratory findings were collected. RESULTS: The stomach volume measured using 3D CT gastrography ranged from 268 to 751 mL, whereas the stomach capacity was 572 ± 301.6 mL and 438.5 ± 163.4 mL in patients with body mass index (BMI) ≥ 25 kg/m2 and < 25 kg/m2, respectively. Visceral fat volume, abdominal circumference, and visceral-to-subcutaneous fat ratio tended to be associated with increased stomach volume. Multivariate analysis showed that BMI and visceral fat volume were significantly associated with stomach volume in female patients. CONCLUSIONS: The results of this study indicated the association of stomach volume with obesity status. Objective estimation of the individual stomach presented the possibility of tailored therapeutic approach to obese patients requiring more effective bariatric treatment.

BACKGROUND & AIMS: Mucosal healing (MH) has become a goal of therapy for Crohn's disease (CD), but frequent endoscopies are not feasible. We aimed to develop and validate a non-invasive index to assess mucosal inflammation in children with CD. METHODS: We collected data from the multi-center prospective ImageKids study, in which children with CD underwent ileocolonoscopy with magnetic resonance enterography. We investigated the association of pediatric CD activity index (PCDAI) items and laboratory test results with the simple endoscopic score for CD (SESCD). We used these data in a blended mathematical judgmental clinimetric approach to develop a weighted categorized index to identify children with CD who have MH, which we called the MINI index. We validated the index using data from 3 independent patient cohorts. The derivation and validation cohorts included 154 and 168 children, respectively (age 14.1 ± 2.5 years and 14.2 ± 3.9 years), of whom 16% and 36% had MH (defined as SESCD<3). RESULTS: In multivariable models, the stooling item of the PCDAI, erythrocyte sedimentation rate, and level of fecal calprotectin were associated with SESCD (all P < .05). We added data on level of C-reactive protein to develop the MINI index. MINI scores below 8 identified children with MH with 88% sensitivity and 85% specificity in the derivation cohort and with 84% sensitivity and 87% specificity in the validation cohorts. Ninety percent of the patients in the validation cohort with scores of 8 or more had active mucosal inflammation, yet 78% of patients with scores below 8 had MH. Scores below 6 increase the positive predictive value to 86%. CONCLUSIONS: We developed an index to non-invasively assess mucosal inflammation in children with CD. This index, identifies children with MH with high sensitivity and specificity. The added benefit of MINI over measurement of fecal calprotectin was small but significant, especially for patients with concentrations of fecal calprotectin from 100 to 599 µg/g.

Chronic Hepatitis B (HBV) is the most important cause of liver disease worldwide. There is a need for low-cost tests to aid in diagnosis and management of HBV infection in resource-limited settings. We evaluated the utility of several rapid diagnostic tests (RDT) in three different continents (Europe, South America, Africa). The HBsAg RDT showed optimal sensitivity and specificity. The anti-HBeAb RDT showed acceptable sensitivity and excellent specificity. Our results suggest that these RDTs could be used for screening and management of HBV.

BACKGROUND: The Test of Masticating and Swallowing Solids (TOMASS) has been developed to provide clinicians with objective data regarding the efficiency of oral phase function and solid bolus ingestion. AIMS: To determine if the TOMASS will detect changes in the oral phase of swallowing imposed by topical anaesthesia, thus providing validation of its clinical utility. METHODS & PROCEDURES: Per the standard protocol, 10 healthy participants ate one-quarter of an Arnotts SaladaTM biscuit. The number of bites per cracker, number of masticatory cycles, number of swallows and total time taken were recorded at baseline, following application of topical oral anaesthetic; this was additionally compared with a post-anaesthetic condition. Median and interquartile range (IQR) were calculated. Wilcoxon signed-rank tests were conducted to evaluate trial effect, and Friedman's tests were used to detect differences in the number of bites, number of swallows, number of chews and time taken to eat the crackers. OUTCOMES & RESULTS: Results indicated that the number of both bites and swallows did not significantly change across conditions (χ²(2) = 0.105, p = 0.949, χ²(2) = 1.357, p = 0.507); however, the number of chews for the anaesthetic condition was significantly higher when compared with the baseline (p = 0.02) and post-anaesthesia conditions (p = 0.02). Further, the durations of ingestion in the anaesthetic condition were significantly longer than the baseline (p = 0.01) and post-anaesthesia (p = 0.01) conditions. Across all measures, there were no differences between baseline and post-anaesthesia conditions. CONCLUSIONS & IMPLICATIONS: Although further exploration is required, these early data suggest the TOMASS is a sensitive measure in the evaluation of the oral-phase preparation of solid textures.

PURPOSE OF THE REVIEW: This article reviews recent developments in the instrumental assessment of swallowing in children with a specific focus on research published between January 2017 and June 2018. RECENT FINDINGS: Instrumental swallowing assessments reported in the time period included: videofluoroscopic study of swallowing, digital cervical auscultation, dynamic ultrasound, high-resolution impedance manometry, nasal airflow thermistry and respiratory inductance plethysmography. Several studies were found exploring tools to objectively quantify videofluoroscopic study of swallowing data; swallowing from the mouth through to stomach was addressed including approaches to analysing mastication as well as evaluating oesophageal motility disorders. SUMMARY: Even though a vast range of instrumentation were studied, lack of clarity on clinical feasibility and objective measures that facilitate medical decision-making in practice mean further research is required to provide guidance on implementation. Promising novel approaches to aid the quantification of swallowing physiology from the mouth, pharynx and through to the oesophagus are emerging.

Gastrointestinal (GI) bleeding represents a broad differential of disease throughout the GI tract. The proper diagnostic evaluation of patients presenting with symptoms of GI bleeding depends on the overall clinical acuity and suspected source locations. The radiologic assessment of these patients is centered around computed tomography (CT) angiography, CT enterography, conventional angiography, and nuclear scintigraphy.

BACKGROUND AND PURPOSE: Esophageal function testing is being increasingly utilized in diagnosis and management of esophageal disorders. There have been several recent technological advances in the field to allow practitioners the ability to more accurately assess and treat such conditions, but there has been a relative lack of education in the literature regarding the associated Common Procedural Terminology (CPT) codes and methods of reimbursement. This review, commissioned and supported by the American Neurogastroenterology and Motility Society Council, aims to summarize each of the CPT codes for esophageal function testing and show the trends of associated reimbursement, as well as recommend coding methods in a practical context. We also aim to encourage many of these codes to be reviewed on a gastrointestinal (GI) societal level, by providing evidence of both discrepancies in coding definitions and inadequate reimbursement in this new era of esophageal function testing.

AIM: We aimed to determine colorectal length with the 3D-Transit system by describing a 'centreline' of capsule movement and comparing it with known anatomy, as determined by magnetic resonance imaging (MRI). Further, we aimed to test the day-to-day variation of colorectal length assessed with the system. METHOD: The 3D-Transit system consists of electromagnetic capsules that can be tracked as they traverse the gastrointestinal tract. Twenty-five healthy subjects were examined with both 3D-Transit and MRI. Another 21 healthy subjects were examined with 3D-Transit on two consecutive days. RESULTS: Computation of colorectal length from capsule passage was possible for 60 of the 67 3D-Transit recordings. The length of the colorectum measured with MRI and 3D-Transit was 95 (75-153) cm and 99 (77-147) cm, respectively (P = 0.15). The coefficient of variation (CV) between MRI and 3D-Transit was 7.8%. Apart from the caecum/ascending colon being 26% (P = 0.002) shorter on MRI, there were no other differences in total or segmental colorectal lengths between methods (all P > 0.05). The length of the colorectum measured with 3D-Transit on two consecutive days was 102 (73-119) cm and 103 (75-123) cm (P = 0.67). The CV between days was 7.3%. CONCLUSION: The 3D-Transit system allows accurate and reliable determination of colorectal length compared with MRI-derived colorectal length and between days. Antegrade or retrograde capsule movement relative to this centreline, as well as the length and speed of movements, may be determined by future studies to allow better classification and treatment in patients with dysmotility.

ANTECEDENTES: la colangiografía endoscópica enfrenta el desafío del control de costos en un área de constantes avances tecnológicos. La reutilización es el uso de un dispositivo médico más veces de las especificadas por el fabricante. Esta práctica se halla precedida por las maniobras de reprocesamiento y amparada por la legislación vigente. OBJETIVOS: cuantificar la reducción en el costo de los insumos y evaluar las complicaciones. Método: estudio prospectivo, descriptivo y análisis sobre minimización de costos comparando la reutilización de dispositivos médicos con el uso único de los mismos. RESULTADOS: durante un período de tres meses se realizaron 144 estudios. Con la estrategia de reutilización, se utilizaron: 9 papilótomos, 12 guías hidrofílica, 3 canastillas de Dormia, 4 balones extractor, 5 balones dilatadores y 2 cuchillos de precorte. Representó un costo total de U$ 10 943 (promedio de costo de materiales por cada estudio: U$ 76). Con la estrategia de uso único se hubieran utilizado: 144 papilótomos, 144 alambres guías, 24 canastillas de Dormia, 20 balones dilatadores, 72 balones extractores y 24 agujas de precorte. Esta estrategia hubiera generado un costo total de U$ 126 280 (promedio por estudio U$ 877). Al comparar los valores entre ambas estrategias observamos una minimización significativa en el costo (p< 0.001). No se registraron complicaciones. Conclusión: Con la estrategia de reutilización de los DM los costos se minimizaron significativamente sin generarse complicaciones
BACKGROUND: cost control is challenging endoscopic cholangiography in an area of constant technological advances. Reusing is using a medical device more times than what was specified by the manufacturer. This practice is preceded by reprocessing maneuvers and protected by the applicable laws. OBJECTIVES: to quantify the cost reduction of supplies and assess the complications. Method: a prospective descriptive study and an analysis of cost minimization by comparing the reuse and the single use of medical devices. Results: 144 studies were conducted during a period of three months. The reuse strategy included: 9 papillotomes, 12 hydrophilic guide wires, 3 Dormia baskets, 4 balloon extraction catheters, 5 balloon dilatation catheters and 2 pre-cut knives. It accounted for a total cost of USD 10,943 (average cost of materials per study: USD 76). The single-use strategy would have included: 144 papillotomes, 144 hydrophilic guide wires, 24 Dormia baskets, 20 balloon extraction catheters, 72 balloon dilatation catheters and 24 pre-cut needle knives. This strategy would have amounted to a total cost of USD 126,280 (average per study: USD 877). By comparing the values of both strategies, a significant minimization is seen in the cost (p< 0.001). No complications were seen. CONCLUSION: the strategy for reusing MD involveda significant minimization of costs without causing any complications.

BACKGROUND: Diarrhea, a common complication after solid organ transplant (SOT), is associated with allograft failure and death. No evidence-based guidelines exist for the evaluation of diarrhea in SOT recipients. We performed a cost analysis to derive a testing algorithm for the diagnosis of community-onset diarrhea that minimizes costs without compromising diagnostic yields. DESIGN: A cost analysis was performed on a retrospective cohort of 422 SOT admissions for community-onset diarrhea over an 18-month period. A stepwise testing model was applied on a population level to assess test costs relative to diagnostic yields. RESULTS: Over an 18-month period, 1564 diagnostic tests were performed and 127 (8.1%) returned positive. Diagnostic testing accounted for $95 625 of hospital costs. The tests with the lowest cost per decrease in the false-omission rate (FOR) were stool Clostridium difficile polymerase chain reaction (PCR) ($156), serum cytomegalovirus quantitative PCR ($1529), stool norovirus (NV) PCR ($4673), and stool culture ($6804). A time-to-event analysis found no significant difference in the length of hospital stay between patients with and without NV testing (P=.520). CONCLUSIONS: A stepwise testing strategy can reduce costs without compromising diagnostic yields. In the first-stage testing, we recommend assessment for C. difficile, cytomegalovirus, and food-borne bacterial pathogens. For persistent diarrheal episodes, second-stage evaluation should include stool NV PCR, Giardia/Cryptosporidium enzyme immunoassay, stool ova and parasite, reductions in immunosuppressive therapy, and possibly endoscopy. Although NV testing had a relatively low cost per FOR, we recommend NV testing during second-stage evaluation, as an NV diagnosis may not lead to changes in clinical management or further reductions in length of hospital stay.

BACKGROUND AND OBJECTIVES: The majority of patients with irritable bowel syndrome (IBS) are diagnosed and treated in primary care. The aim of this study was to investigate the implementation of the Rome criteria in daily primary care clinical practice and adherence of general practitioners (GPs) to recommended diagnostic approaches for IBS. PATIENTS AND METHODS: A survey consisting of 18 questions was distributed across 11 European countries and was used to assess GPs' diagnostic approach of IBS, the use of Rome criteria in daily practice and GPs' perspective on the aetiology of the disorder. RESULTS: Overall, 185 GPs completed the survey. In daily clinical practice, 32% of GPs reported that they usually make a positive diagnosis on the basis of symptoms only, whereas 36% of GPs reported regular use of the Rome criteria to diagnose IBS. Furthermore, 62% of the responders reported that they applied additional diagnostics, such as blood tests, 31% found it necessary to perform endoscopy to make a positive diagnosis of IBS and 29% referred patients with IBS to a specialist. Psychological factors were the most frequently selected potential aetiological factor of IBS (88% of GPs). Overall, 52% of GPs reported systematically including questions on psychological symptoms in the assessment of history of IBS. CONCLUSION: Only about one-third of GPs regularly used the Rome criteria to diagnose IBS. In daily primary care practice, IBS largely remains a diagnosis of exclusion. This has implications in terms of GPs' specialty training and questions the applicability of IBS guidelines in daily care, which advocate an early, positive, symptom-based diagnosis.

AIMS: To estimate the cost-effectiveness of a new strategy that uses an amino acid formula in the elimination diet of infants with suspected cow's milk allergy (CMA). MATERIALS AND METHODS: This pharmacoeconomic study was developed from the perspective of the Brazilian Public Healthcare System. The new strategy proposes using an amino acid formula in the diagnostic elimination diet of infants (≤24 months) with suspected CMA. The rationale is that infants who do not respond to the amino acid formula do not suffer from CMA. Patients with a positive oral challenge test receive a therapeutic elimination diet based on Brazilian Food Allergy Guidelines. This approach was compared to the current recommendations of the Brazilian Food Allergy Guidelines. A decision model was constructed using TreeAge Pro 2012 software. Model inputs were based on a literature review and the opinions of a panel of experts. A univariate sensitivity analysis of incremental cost-effectiveness ratios was performed. RESULTS: The mean cost per patient of the new amino acid formula strategy was R$3,341.57, while the cost of the current Brazilian guidelines strategy was R$3,641.08. The mean number of symptom-free days per patient, which was used as an indicator of effectiveness, was 900.6 and 875.7 days, respectively. The new strategy is, therefore, dominant. In the sensitivity analysis, the dominance was maintained with parameter variation. LIMITATIONS: In the absence of information in the literature, some premises were defined by a panel of specialists. CONCLUSIONS: The new strategy, which uses an amino acid formula in the elimination diagnostic diet followed by an oral food challenge, is a dominant pharmacoeconomic approach that has a lower cost and results in an increased number of symptom-free days.

BACKGROUND: Obscure gastrointestinal bleeding (OGIB) is defined as persistent or recurrent bleeding associated with negative findings on upper and lower gastrointestinal (GI) endoscopic evaluations. The diagnosis and management of patients with OGIB is particularly challenging because of the length and complex loops of the small intestine. Capsule endoscopy (CE) is 1 diagnostic modality that is used to determine the etiology of bleeding. OBJECTIVES: The objective of this analysis was to review the diagnostic accuracy, safety, and impact on health outcomes of CE in patients with OGIB in comparison with other diagnostic modalities. DATA SOURCES: A literature search was performed using Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid Embase, the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database, for studies published between 2007 and 2013. REVIEW METHODS: Data on diagnostic accuracy, safety, and impact on health outcomes were abstracted from included studies. Quality of evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). RESULTS: The search yielded 1,189 citations, and 24 studies were included. Eight studies reported diagnostic accuracy comparing CE with other diagnostic modalities. Capsule endoscopy has a higher sensitivity and lower specificity than magnetic resonance enteroclysis, computed tomography, and push enteroscopy. Capsule endoscopy has a good safety profile with few adverse events, although comparative safety data with other diagnostic modalities are limited. Capsule endoscopy is associated with no difference in patient health-related outcomes such as rebleeding or follow-up treatment compared with push enteroscopy, small-bowel follow-through, and angiography. LIMITATIONS: There was significant heterogeneity in estimates of diagnostic accuracy, which prohibited a statistical summary of findings. The analysis was also limited by the fact that there is no established reference standard to which the diagnostic accuracy of CE can be compared. CONCLUSIONS: There is very-low-quality evidence that CE has a higher sensitivity but a lower specificity than other diagnostic modalities. Capsule endoscopy has few adverse events, with capsule retention being the most serious complication. Capsule endoscopy is perceived by patients as less painful and less burdensome compared with other modalities. There is low-quality evidence that patients who undergo CE have similar rates of rebleeding, further therapeutic interventions, and hospitalization compared with other diagnostic modalities.

OBJECTIVE: To assess the hospital cost associated with colorectal cancer (CRC) treatment by stage at diagnosis, type of cost and disease phase in a public hospital. METHODS: A retrospective analysis was conducted of the hospital costs associated with a cohort of 699 patients diagnosed with CRC and treated for this disease between 2000 and 2006 in a teaching hospital and who had a 5-year follow-up from the time of diagnosis. Data were collected from clinical-administrative databases. Mean costs per patient were analysed by stage at diagnosis, cost type and disease phase. RESULTS: The mean cost per patient ranged from 6,573 Euros for patients with a diagnosis of CRC in situ to 36,894 in those diagnosed in stage III. The main cost components were surgery-inpatient care (59.2%) and chemotherapy (19.4%). Advanced disease stages were associated with a decrease in the relative weight of surgical and inpatient care costs and an increase in chemotherapy costs. CONCLUSIONS: This study provides the costs of CRC treatment based on clinical practice, with chemotherapy and surgery accounting for the major cost components. This cost analysis is a baseline study that will provide a useful source of information for future studies on cost-effectiveness and on the budget impact of different therapeutic innovations in Spain.
