Distinguishing sterile inflammation from graft infection.

We describe the case of a 68-year-old man who underwent ascending aortic replacement and thoracic endovascular aortic repair. Four years later, the patient developed neck pain on the right side and chest computed tomography showed expansion of fluid in the mediastinum which had extended to the neck. Echocardiography revealed advanced severity of aortic regurgitation and decreased ejection fraction. Given the progression of aortic regurgitation, decreased cardiac function, and rapidly expanding fluid accumulation causing neck pain, reoperation was indicated. All microbiological test including polymerase chain reaction were negative indicating absence of any infection. The patient is being followed-up without antibiotics and CT has not shown peri-graft fluid 2 years postoperatively. Since infection cannot be excluded completely, it is important to assess the condition with selective medium, extended culture periods, genetic testing, and consultations with microbiology laboratories when normal culture tests for general bacteria, and fungi are negative which can help avoid drug-resistant bacteria count, elevated medical costs, and drug side effects due to the improper use of antibiotics through proper diagnosis.

Associations between electrocardiographic findings and echocardiographic profiles in patients with hypertrophic cardiomyopathy.

BACKGROUND: The relationships between electrocardiography (ECG) findings and echocardiographic profiles in patients with hypertrophic cardiomyopathy (HCM) are not fully understood. METHODS: One hundred forty patients (mean age: 62.9 ±â€¯15.3 years, 96 men) with HCM were studied. We assessed the associations between ECG findings and echocardiographic findings including maximum left ventricular wall thickness, HCM subtypes and distribution of left ventricular hypertrophy (LVH): the LV was divided into basal, mid, and apical segments by dividing it into thirds along the long axis. RESULTS: In ECG, LVH by voltage criteria, abnormal Q wave, negative T wave, and giant negative T wave (GNT) were observed in 74 (53 %), 30 (21 %), 132 (94 %), and 25 (18 %) of the patients, respectively. In two groups with and without an LVH pattern according to voltage criteria in ECG, there were no significant differences in maximum LV wall thickness, subtype of HCM, and distribution of LVH. Regarding an abnormal Q wave, the proportion of patients with LVH in the basal segment was significantly higher in patients with an abnormal Q wave than in patients without an abnormal Q wave (87 % vs 61 %, p = 0.008). An abnormal Q wave was not observed in patients with LVH confined to the apex. Patients with a GNT included patients with LVH located at only the apex (apical HCM), LVH from the mid segment to apex, and LVH from the base to apex. No GNT was found in patients with hypertrophy located in the upper region from the base to mid segment of the LV. CONCLUSIONS: In patients with HCM, there was no significant correlation between the presence of LVH by voltage criteria in ECG and echocardiographic findings. An abnormal Q wave was associated with disproportionate hypertrophy of the basal wall and a GNT reflected the presence of LVH in the apical segment.

Strategies for managing left main trunk compression by left atrial appendage clip: a case report.

Background: Closure of the left atrial appendage (LAA) using a clip in at-risk patients reduces stroke risk. The rate of LAA closure procedures is increasing worldwide; however, complications have been reported, with coronary compression being one possible lethal complication associated with the anatomical structures around the LAA. Case summary: A 75-year-old man presented with a diagnosis of a φ50 mm saccular thoracic aortic aneurysm. He had a history of chronic atrial fibrillation and functional tricuspid regurgitation. We performed total arch replacement with an open stent graft, tricuspid ring annuloplasty, left atrium Maze procedure, left atrial plication, and LAA closure using a LAA clip. The blood pressure of the patient dropped after closing the pericardium post-operatively. Coronary artery angiography (CAG) confirmed 90% stenosis at the left coronary main trunk (LMT) origin. Percutaneous coronary intervention (PCI) was performed, and the haemodynamics settled. Discussion: The distance from the anterior wall of the LAA ostium to the LMT can be a risk for AtriClip-induced LMT compression. A different surgical strategy, such as internal sutures or surgical stapler for LAA closure, should be considered under such a condition. Selecting an appropriately sized AtriClip is essential while using the clip, placing it close to the orifice, and visually checking for compression after insertion to prevent LMT stenosis. When LMT compression by the clip was confirmed, levelling the endocardial adipose tissue with the LAA landing zone, cutting and removing the clip or coronary artery bypass grafting during operation, and PCI during CAG should be considered.

Thoracic endovascular aortic repair for hemolysis 17 years after insertion of classical elephant trunk: a case report.

BACKGROUND: The classical elephant trunk (ET) technique is a very useful surgical procedure; however, haemolysis in the aorta associated with ET has been previously reported. It normally occurs within several years after the surgery, and it is a rare case of rapidly progressing haemolysis 10 or more years after aortic arch replacement with ET. CASE PRESENTATION: A 53-year-old man with a history of Stanford type A aortic dissection (DeBakey type Is), who was treated with total arch aortic replacement and aorto-femoral bypass using a prosthetic graft 17 years ago, developed severe progressive haemolytic anaemia. The ET used for the initial surgery was narrowed, and mechanical haemolysis was suspected. We assumed that progressive mechanical haemolysis occurred because of degeneration of the prosthetic graft. Thoracic endovascular aortic repair was performed, and haemolysis and anaemia were mitigated postoperatively. CONCLUSIONS: Haemolysis occurred 17 years after the initial surgery with ET. When haemolysis is suspected in a patient with ET, it must be identified as a cause of haemolysis even if 10 years or more have passed since the ET was inserted. To prevent this complication, attention should be paid to an appropriate ET length and diameter to avoid folding of the ET, particularly when the true cavity diameter is small.

Transient decrease in the depth of the negative T wave in apical hypertrophic cardiomyopathy is a sign of left anterior descending artery stenosis: a case series.

Background: In patients with apical hypertrophic cardiomyopathy (HCM), electrocardiography (ECG) often shows left ventricular hypertrophy (LVH) and a negative T wave. A negative T wave often disappears over time due to degeneration of the apical myocardium. However, there are limited reports on the temporary change of a negative T wave in patients with HCM. Case summary: We report three apical HCM patients with LVH and T wave inversion on their previous ECG who showed a temporary decrease in the depth of the negative T wave. All of them had significant stenosis of coronary arteries including the left anterior descending artery (LAD). After revascularization for the LAD lesion, their ECG returned to the previous depth of the negative T wave. Discussion: The cases presented here suggested that a temporary decrease in the depth of the negative T wave in apical HCM patients may be one of the signs of ischaemia in the anterior-apical region caused by severe stenosis of the LAD.

Very long-term prognosis in patients with hypertrophic cardiomyopathy: a longitudinal study with a period of 20 years.

AIMS: We aim to clarify the prognosis on patients with hypertrophic cardiomyopathy (HCM) for a follow-up period of more than 10 years. METHODS AND RESULTS: We retrospectively analysed 102 consecutive patients with HCM diagnosed by 31 December 2000. Complete and detailed clinical records were obtained for 93 (91%) of the 102 patients. Sixty-three (68%) of the 93 patients were men, and the mean age of the patients at the initial evaluation was 51.5 ± 13.0 years. During the mean follow-up period of 19.6 ± 8.1 years (median 20.1 years), HCM-related deaths occurred in 20 patients (21% [1.1%/year]). HCM-related adverse events (including HCM-related deaths and nonfatal HCM-related events: hospitalization for heart failure, embolic stroke admission, and sustained ventricular tachycardia with haemodynamic instability or appropriate implantable cardioverter-defibrillator discharge) occurred in 45 patients (48%). The first HCM-related adverse events occurred in approximately 20% of the patients in every decade, the first decade to the third decade, from the initial evaluation. Forty-seven patients (51%) had documentation of atrial fibrillation at the last follow-up. There were seven patients in the end-stage HCM group at the initial evaluation, and 22 patients (24%) had progression to end-stage HCM during the follow-up period. CONCLUSIONS: In our cohort of patients, HCM-related mortality was relatively favourable. However, approximately half of the patients suffered from HCM-related adverse events during the follow-up period of 20 years. It is important for HCM patients to be carefully followed up over the long-term because HCM is a lifelong disease.

Early Experience of Tafamidis Treatment in Japanese Patients With Wild-Type Transthyretin Cardiac Amyloidosis From the Kochi Amyloidosis Cohort.

BACKGROUND: Tafamidis has emerged as an effective treatment for patients with wild-type transthyretin cardiac amyloidosis (ATTRwt CA). The early experience of tafamidis treatment for Japanese patients with ATTRwt CA is reported here.Methods and Results: Over the past 2 years, in 82 patients with ATTRwt CA (mean age of 81.7±6.0 years), tafamidis treatment was initiated for 38 patients. The remaining 44 patients were not administered tafamidis. The most frequent reason for non-administration of tafamidis was advanced heart failure and the second most reason was the patient's frailty. In patients who received tafamidis treatment, there was no discontinuation of tafamidis due to adverse events, the rate of cardiovascular-related hospitalizations per year was 0.19, and the 1-year survival rate was 92%. In the patients who continued tafamidis for 12-18 months, there was no significant deterioration from baseline for high-sensitivity cardiac troponin T level, plasma B-type natriuretic peptide level, left ventricular ejection fraction, inter-ventricular septum wall thickness, or value of left ventricular longitudinal strain. CONCLUSIONS: Tafamidis treatment was introduced for approximately half of the study patients with ATTRwt CA in real-world practice. Tafamidis is likely to be safe and may maintain the status of disease severity in the short-term in selected Japanese patients with ATTRwt CA. Further research is needed to determine appropriate patient selection for tafamidis treatment and efficacy of tafamidis in the long term.

Donepezil, an anti-Alzheimer's disease drug, promotes differentiation and regeneration in injured skeletal muscle through the elevation of the expression of myogenic regulatory factors.

We previously demonstrated that donepezil, an anti-Alzheimer's disease drug, improved skeletal muscle atrophy by enhancing the angiogenesis of endothelial cells and activating the proliferation of satellite cells in a mouse model of peripheral arterial disease. However, the effect of donepezil on muscle differentiation during regeneration remains unclear. Therefore, we measured the expressions of myogenic regulatory factors and late muscle differentiation markers in donepezil-treated C2C12 myoblast cells before and after the induction of cell differentiation. The results indicate that the expressions of myogenin, troponin T (TnT) and myosin heavy chain (MyHC) were significantly increased and myotube formation was accelerated in donepezil-treated cells under the differentiation condition. However, the promotive effect of donepezil on muscle differentiation could not be reproduced by the addition of acetylcholine (ACh) and was not disrupted after treatment with ACh receptor blockers. Moreover, other kinds of acetylcholinesterase inhibitors failed to promote muscle differentiation in C2C12 cells. These results indicate that the specific characteristics of donepezil in the promotion of muscle differentiation are independent of its acetylcholinesterase-inhibitory action. We further found that donepezil induced an incremental shift of the cross-sectional area of myofibers and elevated the expressions of myogenin, TnT and MyHC in a mouse model of cardiotoxin injury. These results suggest that donepezil promotes the differentiation of muscle regeneration upon injury via the elevation of the expressions of myogenic regulatory factors and late muscle differentiation markers. Our findings suggest that donepezil can be a useful therapeutic agent for injured skeletal muscle treatment.

Wild-Type Transthyretin Amyloidosis in Female Patients　- Consideration of Sex Differences.

Background: With recent advances in non-invasive diagnostic tools, some studies indicate that wild-type transthyretin amyloidosis (ATTRwt) may be more common in females than previously reported. However, the clinical characteristics of female ATTRwt patients have not been determined. Methods and Results: Of the 78 consecutive patients with ATTRwt in our cohort, 14 (17.9 %) were female. Compared with male patients, female ATTRwt patients had smaller left ventricular (LV) wall thicknesses (ventricular septum thickness 12.9 vs. 14.2 mm [P=0.081]; posterior wall thickness 12.7 vs. 13.6 mm [P=0.035]) and a higher LV ejection fraction (EF; mean [±SD] 58.4±8.9% vs. 48.9±11.8%; P=0.006). However, the severity of heart failure (HF), as assessed by HF stage, New York Heart Association functional class and B-type natriuretic peptide concentrations, did not differ between female and male patients. Moreover, LV mass index and relative wall thickness were increased and the stroke volume index was reduced in both female and male patients. In organ biopsies, female patients had a higher sensitivity to transthyretin deposition from abdominal fat than male patients (positive abdominal fat biopsy 80.0 % vs. 26.5%; P=0.016). Conclusions: This study suggests that a relatively large proportion of elderly females have ATTRwt. Female ATTRwt patients had HF symptoms even at the stage of mild LV hypertrophy and preserved EF. Abdominal fat biopsy may be useful to diagnose ATTRwt, especially in female patients with HF.

Tenosynovial and Cardiac Transthyretin Amyloidosis in Japanese Patients Undergoing Carpal Tunnel Release.

Background: Wild-type transthyretin cardiac amyloidosis (ATTRwt-CA) is a life-threatening progressive disease. Recent studies have shown that the detection of transthyretin (TTR) amyloid in tenosynovial tissue may play an important role in the diagnosis of cardiac amyloidosis. The aim of this study was to determine the prevalence of TTR amyloid deposits in surgical tissue of patients undergoing carpal tunnel surgery and to clarify the clinical significance of concomitant cardiac examination with 99 mTc-labeled pyrophosphate (99 mTc-PYP) scintigraphy in those patients with TTR deposition. Methods and Results: We evaluated 79 consecutive patients undergoing carpal tunnel release surgery and biopsy of tenosynovial tissue. The mean (±SD) age of the patients at surgery was 71.6±12.5 years (range 30-95 years); 32 patients (41%) were male. TTR amyloid deposition in tenosynovial tissue was observed in 27 patients (34%). Sixteen of those 27 patients underwent 99 mTc-PYP scintigraphy. Of those 16 patients, 3 (19%) had Grade 2 uptake on 99 mTc-PYP scintigraphy. None of the 3 patients with a diagnosis of ATTRwt-CA had apparent cardiac symptoms and left ventricular wall thickness >13 mm. Conclusions: Concomitant cardiac examination with 99 mTc-PYP scintigraphy in patients who had TTR amyloid deposition in tenosynovial tissue resulted in the identification of 19% of patients with a diagnosis of ATTRwt-CA. This diagnostic approach seems to be useful for the early diagnosis of the disease.

[A case of obstructive jaundice and duodenal stenosis caused by vaginal cancer and retroperitoneal metastasis].

A 76-year-old woman with a history of radiation therapy for vaginal cancer was referred to our hospital because of fever and hepatobiliary dysfunction. Computed tomography showed stenosis of the lower bile duct and edema-like changes in the duodenum from the descending to transverse parts. Endoscopic biliary stenting was performed according to the rendezvous method. Squamous cell carcinoma, similar to vaginal cancer, was found on pathological examination of the duodenum. We accordingly diagnosed obstructive jaundice and duodenal stenosis caused by vaginal cancer and retroperitoneal metastasis. To the best of our knowledge, other such cases have not been reported.

Pancreatic Hamartoma Difficult to Diagnose Preoperatively.

Abdominal ultrasonography in a 70-year-old woman showed a hypoechoic mass, 14 mm in diameter, in the pancreatic body. Computed tomography showed a mass with contrast effect in the pancreatic body. Test results for endocrine factors or tumor markers were normal. The initial consideration was nonfunctional pancreatic neuroendocrine tumor. Over 8 years of monitoring, the tumor diameter increased to 18 mm, until pancreatic tumor enucleation was performed. The postoperative diagnosis was pancreatic hamartoma, a rare type of benign pancreatic tumor. The preoperative diagnosis of pancreatic hamartoma is difficult, but consideration must be given to the possibility of hamartoma when encountering pancreatic tumors.

Usefulness of self-expandable metal stents for malignant biliary obstruction using a short-type single-balloon enteroscope in patients with surgically altered anatomy.

OBJECTIVES: To evaluate the efficacy and safety of self-expandable metal stent (SEMS) placement for unresectable malignant biliary obstruction (MBO) using a short-type single-balloon enteroscopy (short SBE) in patients with surgically altered anatomy (SAA). METHODS: The technical success rate, clinical success rate, recurrent biliary obstruction (RBO), time to RBO (TRBO), procedure related adverse events, and reintervention after RBO were evaluated from September 2011 to June 2020. RESULTS: Thirty-seven patients (11 patients with distal MBO and 26 with hilar MBO) who underwent SEMS placement were included in the analysis. The technical and clinical success rates were 100% and 94.6%. Seven patients underwent bilateral stenting (partial stent-in-stent placement) for hilar MBO. The RBO rate was 13.5% (5/37) and the median TRBO was 212 (interquartile range [IQR], 154-296) days. No food impaction occurred in this study. Procedure related adverse events occurred in 5.4% (2/37) of cases. Reintervention was attempted in five patients and all succeeded (four patients underwent SEMS replacement, and one underwent plastic stent placement). CONCLUSIONS: SEMS placement for unresectable MBO using a short SBE in patients with SAA is effective and safe in similar ways to that in patients with normal anatomy in terms of bilateral stenting, stent patency, and reintervention.

Status of single-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy: Systematic review and meta-analysis on biliary interventions.

BACKGROUND AND AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy is still challenging. Usefulness of single-balloon enteroscopy (SBE)-assisted ERCP has been increasingly reported. Short SBE is considered beneficial with a 152-cm working length and a 3.2-mm working channel. This has increased the variety of devices that can be used during ERCP procedures. The aim of this pooled analysis was to evaluate the efficacy of SBE-assisted ERCP in patients with surgically altered anatomy and elucidate the current status. METHODS: This systematic review only involved biliary interventions which excluded pancreatic cases. Studies involving SBE-assisted ERCP in patients with Roux-en-Y gastrectomy, hepaticojejunostomy with Roux-en-Y, pancreaticoduodenectomy (Whipple or Child procedure), or Billroth II gastrectomy were analyzed. Enteroscopy, biliary cannulation, and procedural success were assessed by pooling data in a random-effect model, according to the degree of heterogeneity, to obtain a proportion with 95% confidence interval (CI). The outcomes observed for conventional and short SBE cases were also reported. RESULTS: Overall, 1227 SBE-assisted ERCP procedures from 21 studies were included. The pooled enteroscopy, biliary cannulation, and procedural success rates were 86.6% (95% CI, 82.4-90.3%), 90% (95% CI, 87.1-92.5%), and 75.8% (95% CI, 71.0-80.3%), respectively. Adverse events occurred in 6.6% (95% CI, 5.3-8.2%) of the procedures. Although good outcomes were reported for short SBE-assisted ERCP, these should not be directly compared to the outcomes observed for conventional SBE, as they assume different backgrounds and include confounding variables. CONCLUSIONS: Single-balloon enteroscopy-assisted ERCP in patients with surgically altered anatomy on biliary interventions is effective.

Validation of the Kumamoto criteria for prediction of 99m technetium pyrophosphate scintigraphy positivity as a strategy for diagnosis of transthyretin cardiac amyloidosis: A retrospective cohort study in Kochi.

BACKGROUND: Early diagnosis of transthyretin cardiac amyloidosis (ATTR-CA) is important. The aim of this study was to validate the 'Kumamoto criteria' for prediction of technetium-99m pyrophosphate (99mTc-PYP) scintigraphy positivity. METHODS: One hundred fifty patients (median age: 79.4 years, 117 males) with the possibility of ATTR-CA who underwent 99mTc-PYP scintigraphy were assessed. We divided the patients into 4 groups (groups with score of 0-3) according to the Kumamoto criteria by total points for the following 3 factors: high-sensitivity cardiac troponin T (hs-cTnT) ≥0.0308 ng/ml, left ventricle posterior wall thickness ≥13.6 mm, and wide QRS (QRS ≥ 120 ms). RESULTS: Seventy patients (46.7%) were positive for 99mTc-PYP scintigraphy. 99mTc-PYP positivity rates in the groups with score of 0, 1, 2, and 3 were 4%, 39%, 69%, and 89%, respectively. Compared with the original Kumamoto cohort, our patients in the score 1 group showed a relatively high rate of 99mTc-PYP positivity because hs-cTnT as one of the positive factors had high ability to discriminate the disease. The sensitivity and negative predictive value of hs-cTnT ≥0.0308 ng/ml for 99mTc-PYP positivity were 97.1% and 93.9%. CONCLUSIONS: In the Kochi validation cohort, the Kumamoto criteria were useful for predicting 99mTc-PYP positivity. However, patients in the score 1 group should be assessed cautiously for the possibility of ATTR-CA if the hs-cTnT value is high.

Complications of Endoscopic Ultrasound-Guided Fine Needle Aspiration: A Narrative Review.

Considerable progress has been made recently in the use of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) to diagnose intra-luminal gastrointestinal lesions and extra-luminal lesions near the gastrointestinal tract. Numerous reports have indicated that EUS-FNA has high diagnostic performance and safety, which has led to the routine use of EUS-FNA and an increasing number of cases. Thus, while EUS-FNA has a low rate of complications, endoscopists may encounter these complications as the number of cases increases. Infrequent reports have also described life-threatening complications. Therefore, endoscopists should possess a comprehensive understanding of the complications of EUS-FNA, which include hemorrhage, perforation, infection, and acute pancreatitis, as well as their management. This review examines the available evidence regarding the complications associated with EUS-FNA, and the findings will be useful for ensuring that endoscopists perform EUS-FNA safely and appropriately.

The diaphragm affects echocardiographic measurement of inferior vena cava diameter to predict right atrial pressure.

PURPOSE: It is recommended in current guidelines that the inferior vena cava (IVC) diameter should be measured at 1.0-2.0 cm from the junction with the right atrium. However, right atrial pressure (RAP) is underestimated in some patients who have a small IVC diameter (IVCD) because of a high-echo structure compressing the IVC from the back at that portion. The aim of this study was to identify the structure behind the IVC and to evaluate its influence on RAP. METHODS: We retrospectively studied 116 patients who underwent right-heart catheterization. We reviewed computed tomography (CT) scans and analyzed the relation between RAP and IVCD measured by echocardiography not only in the way recommended in the guidelines, but also in a way that avoided the structure. RESULTS: CT scans revealed that the diaphragm, not the vertebra, was located just behind the IVC in most patients. Sixteen patients (13.8%) had RAP ≥ 10 mmHg. In those patients, when IVCs were measured in a way that avoided the diaphragm, IVCDmax diameter was larger and IVC collapsibility index (IVCCI) tended to be smaller than those when IVCDs were measured according to the guideline methods. The sensitivity of IVCD to predict RAP ≥ 10 mmHg (IVCDmax > 21 mm, IVCCI < 50%) increased from 31.3% to 68.8% with our method. CONCLUSIONS: The high-echo structure pushing the IVC from the back is the diaphragm in most patients. It might be better to measure IVCD using a method that avoids the diaphragm to accurately estimate RAP.

Preoperative Clinical Features and High Pulmonary Wedge Pressure with a Discordant Pattern as Prognostic Factor in Hemodialysis Patients with Severe Aortic Valve Stenosis.

Hemodialysis (HD) is one of the important risks for the development of cardiovascular disease, including aortic valve stenosis (AS). Although aortic valve replacement (AVR) is a beneficial treatment for AS, HD patients are known to show a high rate of mortality after AVR than non-HD patients.We retrospectively studied 109 patients who underwent AVR for severe AS, 18 of which were HD patients. Survival rate after AVR, preoperative clinical data, and surgical procedure were investigated.In preoperative clinical features, left ventricular end-diastolic diameter was larger, intraventricular septum thickness (IVST) was thicker, left ventricular mass index (LVMI) was higher, left ventricular ejection fraction was lower, E/e' was higher, and pulmonary arterial wedge pressure (PAWP) was higher in the HD group than in the non-HD group. During a follow-up period of 3.2 ± 2.3 years after AVR, patients receiving HD had a worse prognosis than those without HD treatment: the 3-year survival rate after surgery in the HD group was 36.2% and that in the non-HD group was 84.9%. With regard to prognostic factors in the whole cohort, significant differences were found in IVST, LVMI, E/e', PAWP, and HD. In patients receiving HD, abnormally high PAWP for their right atrial pressure (RAP) was observed, suggesting that PAWP and RAP were discordant, and univariate analysis revealed that high PAWP was the only predictor of mortality in HD patients after surgery.Preoperative PAWP with a discordant pattern in HD patients might be an important prognostic predictor after AVR.

Comparison of various risk scores for the prognosis of hemorrhagic upper gastrointestinal mucosal disorder.

BACKGROUND: Various risk scores have been proposed that are useful for the management of upper gastrointestinal bleeding (UGIB), which is an important disease in emergency medicine. Few studies have examined the usefulness of Charlson Comorbidity index (CCI) in this disease, which evaluates the patient's general condition by scoring the patient's underlying disease. There have been no studies investigating the efficacy of CCI compared to other risk scores in the management of UGIB requiring endoscopic hemostasis. METHODS: In addition to the Glasgow-Blatchford score, AIMS65 score, and Rockall score, we investigated the efficacy of the outcome prediction obtained by the original CCI and the updated CCI, scored only with respect to the underlying disease. We also examined the cutoff value when using the risk score. This retrospective study included 265 patients with hemorrhagic upper gastrointestinal mucosal lesions who underwent emergency endoscopic hemostasis during a 6-year period between 2011 and 2016 in our hospital. RESULTS: The updated CCI and AIMS65 score correlated with prognosis in multivariate analysis (p = 0.002 and p = 0.003, respectively). In clinical practice, the prognosis might be worse if both updated CCI and AIMS65 score were 3 point or more. CONCLUSION: In addition to the AIMS65 score, the updated CCI can be a useful tool for managing upper gastrointestinal mucosal disorder bleeding that requires endoscopic hemostasis.

Current Status of Needles in the Optimization of Endoscopic Ultrasound-Guided Procedures.

Endoscopic ultrasound (EUS) is among the most important tools for the evaluation of gastrointestinal tumors and affected areas around the gastrointestinal tract. It enables the acquisition of material from abnormal lesions via the gastrointestinal wall for tissue confirmation via endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). EUS-FNA has played a vital role in oncological care and has become the standard method for tissue sampling. The choice of needle type is an important factor determining tissue acquisition and has been evaluated by many researchers. New needles are introduced into the market almost every year, and opinions vary regarding proper needle selection. While there are diverse opinions but no definitive recommendations about the use of one particular device, fine-needle biopsy needles may provide detailed information on a tissue's architecture based on greater sample yields. This permits additional analyses, including genetic sequencing and phenotyping, thereby enabling the provision of more personalized treatment plans. Furthermore, other EUS-guided procedures have been developed, including interventional EUS and through-the-needle devices. Given the continued attempts to improve the diagnostic ability and therapeutic techniques, we review in detail the available types of puncture needles to provide guidance on the selection of the appropriate needle types.
