Abstract
PURPOSE Despite their similar clinical characteristics, appendiceal diverticulitis (AD) and acute appendicitis (AA) are pathologically distinct. This study compared the clinical features of AD and AA and identified relevant risk factors. METHODS Patients who underwent appendectomy with a preoperative diagnosis of either AD or AA were categorized based on histopathological findings. The two groups were compared in terms of various clinical factors. RESULTS Among the 854 patients included in the study, a histopathological evaluation revealed 49 and 805 cases of AD and AA, respectively. A univariate analysis demonstrated that AD was more prevalent than AA among older, taller, and heavier males. A multivariate analysis revealed that male sex, a white blood cell (WBC) count < 13.5 × 103/μL, an eosinophil count ≥ 0.4%, and a mean corpuscular volume (MCV) ≥ 91.6 fL were significant factors differentiating AD from AA. In addition, pathological AD emerged as an independent risk factor for abscess and/or perforation. CONCLUSIONS AD was associated with an older age, robust physique, and significant risk of abscess and/or perforation despite a low WBC count. In addition to imaging modalities, the preoperative factors of male sex, a WBC count < 13.5 × 103/μL, an eosinophil count ≥ 0.4%, and a MCV ≥ 91.6 fL may be useful for distinguishing AD from AA.

Abstract
PURPOSE One-year mortality is important for referrals to specialist palliative care or advance care planning (ACP). This helps optimize comfort for those who cannot be cured or have a lower life expectancy. Few studies have investigated the risk factors for 1-year mortality after gastrectomy for gastric cancer (GC). METHODS A total of 1415 patients with gastric cancer (stages I-IV) who underwent gastrectomy between 2005 and 2020 were included. The patients were randomly assigned to the investigation group (n = 850) and validation group (n = 565) in a 3:2 ratio. In the investigation group, significant independent prognostic factors for predicting 1-year survival were identified. A scoring system for predicting 1-year mortality was developed which was validated in the validation group. RESULTS Multivariate analysis revealed that the following seven variables were significant independent factors for 1-year survival: age ≧78, preoperative comorbidity, total gastrectomy, postoperative complication (Clavien-Dindo classification CD ≧ 3a), stage III and IV, and R2 resection. While developing a 1-year mortality score (OMS), an age ≧78 was scored 2, preoperative comorbidity, total gastrectomy, and postoperative complication (CD ≧ 3a) were scored 1, and stage III, IV, and R2-resection were scored 2, 3, and 3, respectively. OMS 3 had a sensitivity of 91% and a specificity of 66% for predicting death within 1 year. In the validation group, OMS 5 had a sensitivity of 55% and a specificity of 93% for predicting death within 1 year. CONCLUSIONS OMS may provide important information and help surgeons select the timing of ACP in patients with GC.

Abstract
BACKGROUND While most orbital tumors are primary, some are secondary, including extension or invasion from adjacent sites. The diagnosis varies widely, and the treatment strategy depends on the pathological diagnosis. Transcranial and transorbital surgical approaches are typically used. Recently, a transnasal endoscopic approach has emerged as a viable option. We report a case of an intraorbital tumor treated with endoscopic transnasal biopsy and compare the results with those of other surgical approaches. CASE DESCRIPTION A 74-year-old woman visited a nearby hospital due to a right eye protrusion and decreased visual acuity. An intraorbital tumor was detected and the patient was referred to our hospital. Head computed tomography revealed a mass along the posterior wall of the right orbital apex. Contrast-enhanced magnetic resonance imaging showed a 37-mm lesion with a uniform contrast effect and no intracranial extension. Intraorbital lymphoma was considered a differential diagnosis, and a biopsy was performed using an endoscopic transnasal approach. The pathological diagnosis was B-cell lymphoma, and chemotherapy was administered. CONCLUSION The endoscopic transnasal approach for intraorbital tumors is less invasive, highly cosmetic, and useful, especially for medial and inferior orbital lesions.

Abstract
BACKGROUND Development in mechanical thrombectomy is progressing dramatically. Tumor embolism has been rarely reported on the basis of pathological study of the retrieved thrombus. Herein, the authors report a case of cerebral tumor embolism from advanced thyroid cancer, which was successfully treated with mechanical thrombectomy. OBSERVATIONS A 57-year-old man was diagnosed with thyroid cancer with multiple lung metastases and chemotherapy was planned. He experienced left hemiparesis and was bought to the emergency section of the authors' hospital. Magnetic resonance angiography revealed right internal carotid artery occlusion and endovascular treatment was performed. Using a combination of aspiration catheter and stent retriever, white jelly-like embolus was retrieved. The pathological study demonstrated thyroid cancer embolism. Pulmonary vein invasion following lung metastasis of thyroid cancer was most presumably the cause of the tumor embolism. LESSONS Lung metastasis invading the pulmonary vein may be a cause of tumor embolism. Mechanical thrombectomy using a combination of stent retriever and aspiration catheter is effective in removing the tumor embolus and the pathological examination of the embolus is essential.

Abstract
AIM There is a concern that the differential diagnosis of a groin mass depends on a physicians' subjective judgment and experience. We aimed to clarify the significance of US in the diagnosis of a groin mass. MATERIAL AND METHODS This retrospective study included 1,898 patients who underwent US examination of a groin mass. Physicians' diagnoses were compared with US-based diagnoses. Furthermore, the incidence of asymptomatic contralateral hernia was analyzed. The frequency of unnecessary surgery in patients with and without preoperative US was compared. In 1,451 patients who underwent surgery with preoperative US, the preoperative US classification was compared with surgical diagnosis. RESULTS Of 1,805 patients diagnosed with an inguinal hernia by physicians, 190 (10.5%) exhibited no US findings of inguinal hernia. US revealed asymptomatic contralateral hernia in 13.3% of the 1,543 patients in whom a physician detected unilateral inguinal hernia. The frequency of unnecessary surgery was significantly associated with preoperative US (1/1451; 0% vs. 2/351, 0.6%; p=0.0382). The overall US diagnostic accuracy for the inguinal hernia type was 92.7%. CONCLUSIONS US imaging of a groin mass can help avoid unnecessary surgery, detect latent inguinal hernia, and guide surgical planning.

Abstract
An 83-year-old man visited our hospital because of difficulty swallowing. Gastroscopy revealed multiple ulcers and a reddish depression in the lesser curvature of the middle stomach. The initial biopsy showed regenerative atypia, so a gastroscopy was repeated every 3 months thereafter because of suspected malignancy. A biopsy performed 12 months after the initial gastroscopy revealed a well-differentiated adenocarcinoma. After determination of the planned oral resection line by two negative biopsies, laparoscopic distal gastrectomy was performed. The resected specimen showed a 0 - IIa + IIc lesion composed of well-to-moderately differentiated tubular adenocarcinoma, including hand-shaking-type gastric cancer. The oral resection margin was positive due to widespread mucosal extension; therefore, an additional total gastrectomy was needed. Cases of well-differentiated adenocarcinoma and its superficial extension may be difficult to diagnose via endoscopy and biopsy.

Abstract
BACKGROUND Emergency appendectomy is often performed for de Garengeot hernia. However, in some cases, there may be a chance to perform an appendix-preserving elective surgery. CASE DESCRIPTION A 76-year-old woman presented to our hospital with complaints of a right inguinal swelling, which we diagnosed as a de Garengeot hernia using computed tomography (CT). B-mode ultrasonography (US) of the mass showed an appendix 4-6 mm in diameter with a clear wall structure; color Doppler US showed pulsatile blood flow signal in the appendiceal wall. Twenty-eight days later, herniorrhaphy with transabdominal preperitoneal repair (TAPP) was performed without appendectomy. Another 70-year-old woman presented to our hospital with complaints of a painful bulge in the right inguinal region. The diagnosis of de Garengeot hernia was made using CT. B-mode US showed an appendix 5 mm in diameter with a clear wall structure. Color Doppler US showed a pulsatile blood signal in the appendiceal wall. Seven days later, herniorrhaphy with TAPP was performed without appendectomy. CONCLUSION De Garengeot hernia is often associated with appendicitis; however, an appendix-preserving elective herniorrhaphy can be performed if US and intraoperative findings do not suggest appendicitis or circulatory compromise in the appendix.

Abstract
BACKGROUND Excess neurological stress by hemorrhagic stoke induces cardiomyopathy, namely takotsubo cardiomyopathy. Here, the authors report a case of takotsubo myopathy following mechanical thrombectomy for acute large vessel occlusion. OBSERVATIONS A 73-year-old man was emergently brought to the authors’ hospital because of left hemiparesis and consciousness disturbance. An ischemic lesion of the right cerebral hemisphere and the right internal carotid artery occlusion was revealed. Emergently, endovascular treatment was performed, and occlusion of the artery was reanalyzed. However, he suffered from hypotension with electrocardiogram abnormality. Subsequently, coronary angiography was performed, but the arteries were patent. The authors made a diagnosis of takotsubo cardiomyopathy. LESSONS Endovascular recanalization for large cerebral artery occlusion is so effective that it is becoming widely used. Even in the successful recanalization, we need to care for the takotsubo cardiomyopathy.

Abstract
PURPOSE This unicentric, retrospective cohort study aimed to identify the optimal cutoff values of preoperative serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) for the prognosis in patients with stage II/III colon cancer. METHODS After excluding 43 patients with CA19-9 levels < 0.2 U/mL, 588 were included. Receiver operating characteristic curves were constructed to determine the optimal cutoff values of CEA and CA 19-9 for disease relapse. RESULTS The median CEA and CA19-9 values were 3.6 (interquartile range: 2.1-7.2 ng/mL) and 14.3 (interquartile range: 8.1-30.0) U/mL, respectively. The optimal cutoff values of CEA and CA19-9 were 5.4 ng/mL and 22.4 U/mL, respectively. A multivariate analysis of relapse-free survival (RFS) showed that cancer stage, CEA, and CA19-9 were significant independent factors. The RFS of patients with stages II and III colon cancer was significantly stratified by CEA (< 5.4/ ≥ 5.4 ng/mL) and CA19-9 (< 22.4/ ≥ 22.4 U/mL). Prognostication based on the reference values (< 5.0 ng/mL for CEA and < 37.0 U/mL for CA19-9) was less significant than that based on the optimal cutoff values. Both elevated CEA and CA19-9 had no value dependency on RFS: RFS curves were similar between extremely elevated CEA (≥ 54.0 ng/ml) and intermediate CEA (5.4-54.0 ng/ml) and between extremely elevated CA19-9 (≥ 224.0 U/ml) and intermediate CA19-9 (22.4-224.0 U/ml). CONCLUSION The optimal cutoff values of preoperative CEA and CA19-9 for RFS were 5.4 ng/ml and 22.4 U/mL, respectively, in patients with stages II and III colon cancer. Further relapse risk stratification is possible using these values.

Background
Quantification of left ventricular (LV) dyssynchrony is of great interest for resynchronization therapy (CRT). Recently, cardiac computed tomography (CCT) is feasible for evaluation of dyssynchrony. Our aim was to assess a novel simplified approach using CCT to quantify LV dyssynchrony.
Methods
We studied 346 consecutive patients with a wide range of QRS width and ejection fractions (EF). Electrocardiogram-gated contrast-enhanced 256-slice multidetector CT (Brilliance 256 iCT, Philips Medical Systems) was performed before CRT. After CCT scan, the LV endocardial boundaries from short-axis images reconstructed at 5% increments of cardiac cycle were automatically detected, and a time from R-wave to maximal wall motion was calculated for each of the 16 standardized segments for all slices using software "Myocardial Contraction Map" (Argus, Inc Ehime, Japan). The standard deviation of all segments modified by mean heart rate (%SD) was respectively calculated as the global parameter of dyssynchrony. LVEF was also measured using MDCT.
Results
%SD was feasible in all patients, respectably. %SD was significantly different between the different QRS duration groups; narrow QRS (<120ms): 9 ± 5%, relatively wide QRS (120-150 ms): 11 ± 6%, and significantly wide QRS (>150 ms): 14 ± 7% (p <0.001). Moreover, there was significantly difference in %SD between the different morphology groups; normal: 9 ± 7%, Non-left bundle branch block (Non-LBBB): 10 ± 6%, LBBB: 17 ± 7% (p <0.001).
Conclusion
This novel simplified approach by CCT can quantify dyssynchrony in different QRS duration and morphology groups. This method has promise for clinical applications to the evaluation of patients for CRT.

Abstract
BACKGROUND De Garengeot hernia, wherein the appendix is present within a femoral hernia, is a rare disease; therefore, the clinicopathological features remain to be clarified. This study aimed to reveal the clinicopathological characteristics of De Garengeot hernia. CASE PRESENTATION Six patients who underwent appendectomy and herniorrhaphy between 1999 and 2018 were included. The incidence of De Garengeot hernia was 3.2% among the 182 femoral hernias that required surgery during the study period. The median age of the patients was 78 years, and five patients were women. The median body mass index was 20.1. Patients frequently had fever or elevated CRP level. Preoperative diagnoses based on computed tomography were femoral (n = 3), inguinal (n = 2), and De Garengeot (n = 1) hernias. Emergency and elective surgeries were performed in four and two patients, respectively. Histopathological examination of the resected appendix showed gangrenous appendicitis (n = 3), perforated appendicitis (n = 2), and appendiceal ischemia (n = 1) in the patients. Postoperatively, one patient developed sepsis. CONCLUSIONS Preoperative diagnosis of De Garengeot hernia is often difficult, and patients frequently have severe appendicitis. Precise diagnosis is required, and emergency surgery should be considered depending on the severity of appendicitis.

Abstract
BACKGROUND Aneurysmal subarachnoid hemorrhage (aSAH) in the elderly often has a poor prognosis even after surgical treatment in the acute phase. Additionally, subarachnoid clots are the strongest predictors of cerebral vasospasm and tend to be thicker and heavier due to cerebral atrophy. We aimed to compare the conventional surgical treatment in such patients and identify the independent predictors of a favorable outcome after aggressive surgical clot removal. METHODS We included 40 patients with aSAH aged 70 or older. Each patient underwent aneurysmal clipping. We used the modified Rankin Scale to assess the primary outcome of neurologic status at discharge. We performed univariate analysis using the following factors: sex, age, neurologic, and general medical condition, radiographic data, aneurysm location, treatment approach, and timing of the aneurysm surgery. We divided the patients into irrigation and nonirrigation groups. We focused mainly on subarachnoid clots and analyzed them semiquantitatively using computed tomography. RESULTS Clot removal was significantly greater in the irrigation group (n = 21) than in the nonirrigation group (n = 19). The period of intrathecal drainage was significantly shorter in the irrigation group (P = 0.002). The rate of occurrence of new low-density areas on CT scans was higher in the nonirrigation group. Outcomes were better in the irrigation group (P = 0.010). CONCLUSIONS In elderly patients with aSAH in the acute phase, aggressive surgical clot removal after clipping showed favorable outcomes by facilitating early out-of-bed mobilization.

Abstract
Abstract
Background
The degree of mechanical dyssynchrony has been suggested as a predictor for long-term survival after cardiac resynchronization therapy (CRT). There have been little reports of dyssynchrony assessment with the use of cardiac computed tomography (CCT).
Methods
We studied 35 heart failure (HF) patients (average age 67±10 years) referred for CRT with NYHA III-IV heart failure, left ventricular (LV) ejection fraction (EF) 20±10% (all ≤35%), and QRS duration 156±22 ms (all ≥120ms). Electrocardiogram-gated contrast-enhanced 256-slice multidetector CT was performed before CRT. Based on CCT, the LV endocardial boundaries from short-axis images reconstructed at 5% increments of cardiac cycle were automatically detected, and the time from R-wave to maximal wall motion was calculated for each of the 16 standardized segments for all slices using software “Myocardial Contraction Map”. The standard deviation modified by mean heart rate (%SD) was respectively calculated as the global parameter of dyssynchrony. LVEF was also measured using MDCT. The predefined primary end-point was the first HF hospitalization or death over 2 years.
Results
%SD was feasible in all patients, respectably. There were 16 events over 2 years; 11 HF hospitalizations and 5 deaths. Patients with %SD ≥22% (optimal cutoff for outcome by ROC curve analysis) had a better clinical outcome than patients with %SD <22% (p=0.01, Figure).
Conclusion
Patients who had %SD ≥22% assessed by MDCT had a particularly favorable event-free survival following CRT, and this appears to be an important prognostic marker.

Abstract
Abstract
Background
Although catheter ablation of atrial fibrillation (AF) has recently been shown to improve the cardiac function and even mortality in patients with heart failure (HF) and reduced ejection fraction (HFrEF), few studies have examined the outcomes of AF catheter ablation in patients with HF with preserved ejection fraction (HFpEF).
Purpose
To verify the impact of AF catheter ablation on the cardiac function and HF status in patients with HFpEF.
Methods
We studied 306 patients with HF who had a history of an HF hospitalization and/or preprocedural serum BNP levels >100pg/ml (age, 68.9±8.2 years old; male, 66.3%; non-paroxysmal AF, 63.1%, left atrial diameter [LAD], 42.5±6.3 mm; left ventricular ejection fraction [LVEF], 60.6±12.0%) out of 596 consecutive patients who underwent pulmonary vein isolation-based catheter ablation of AF. The patients with an LVEF ≥50% were defined as having HFpEF (n=262; age, 69.0±8.2 years old; male, 64.5%; non-paroxysmal AF, 61.8%, LAD, 42.1±5.9 mm; left LVEF, 64.0±8.2%) and the remaining patients with an LVEF <50% were defined as having HFrEF (n=44, age, 67.9±8.7 years old; male, 77.0%; non-paroxysmal AF, 70.5%, LAD, 44.9±8.2 mm; LVEF, 40.1±10.2%). The patients received periodic follow-ups for 12 months after the catheter ablation. The cardiac function parameters including the echocardiographic findings and HF functional status of the patients were compared between baseline and 12 months, stratified by the HF subgroup.
Results
AF recurred in 60 patients with HFpEF (22.9%) and in 14 with HFrEF (31.8%) during the 12 month follow-up (p=0.27), however, sinus rhythm was maintained at 12 months in most of the patients (253 patients with HFpEF [96.6%] and 42 patients with HFrEF [95.5%]) (p=0.71). Figure 1 compares the changes in the cardiac function parameters and NYHA functional class from baseline to the 12-month follow-up stratified by the HF subgroup. Both the patients with HFpEF and HFrEF had significant improvements in the serum BNP levels, chest thorax ratio, and LVEF determined by echocardiography. LA reverse remodeling as shown by a significant reduction in the LAD was observed in both HF subgroups, however, the E/E', an index of the LV diastolic function, did not significantly change in either of the subgroups. Similar to the patients with HFrEF, an improvement in the NYHA functional class was seen in those with HFpEF.
Conclusions
Catheter ablation of AF may benefit patients with HFpEF as well as those with HFrEF. Sinus rhythm maintenance achieved by AF catheter ablation in patients with HFpEF may lead to LA reverse remodeling and a better LV systolic function, thereby improving the NYHA functional class. It is unclear whether changes in the LV diastolic function may contribute to this favorable process.

Abstract
Infections caused by Aspergillus species are often life-threatening. Drugs effective for Aspergillus infection are limited. Voriconazole is one of the most important drugs, however, considerable portion of patients experience liver toxicity and have to stop the drug administration. We frequently experience liver toxicity even though the serum concentration of voriconazole is within the target range. Historically, in some life-threatening situations like tuberculosis, where a suitable alternative is unavailable, rechallenge has been attempted. However, there have been no report on the rechallenge of voriconazole. We report cases of successful re-administration of voriconazole after liver toxicity.

Abstract
BACKGROUND Due to prognostic heterogeneity within a stage of gastric cancer (GC), identification of patients with a high risk for recurrence after resection is important. We aimed to identify the prognostic significance of preoperative serum carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9) levels in patients with Stage I, II, and III GC who underwent R0 gastrectomy. METHODS A total of 794 patients were included in this study after excluding 72 patients with CA19-9 <1.0 U/mL. Receiver operating characteristic curves were drawn to assess the optimal cut-off values of CEA and CA19-9 for disease recurrence. RESULTS The optimal cut-off values of CEA and CA19-9 levels were 2.9 ng/mL and 46.3 U/mL, respectively. Multivariate analysis for relapse-free survival (RFS) showed that stage of GC, CA19-9 levels, postoperative adjuvant chemotherapy, and venous invasion were significant independent factors. The RFS and overall survival (OS) of patients with CA19-9 ≥ 46.3 U/mL were significantly lower than those with CA19-9 < 46.3 U/mL in Stage III GC. However, the RFS of GC patients with CA19-9 ≥ 463 U/mL tended to be better than those with CA19-9 levels between 46.3 and 463 U/mL. CONCLUSIONS The RFS and OS of patients with CA19-9 ≥ 46.3 U/mL were significantly lower than those with CA19-9 < 46.3 U/mL in Stage III GC. However, there was no value dependency of extremely elevated CA19-9 on RFS. Further risk stratification can be obtained by measuring preoperative serum CA19-9 in stage III GC.

Abstract
Patients with intestinal ischemia associated with acute aortic dissection often require emergent bowel resection, which results in serious complications. We present a case of successful surgical management of extensive bowel necrosis caused by acute aortic dissection. A 42-year-old man underwent emergent subtotal resection of the small intestine, right colectomy, tube gastrostomy, and transverse colostomy; however, intestinal continuity was not restored. He developed two major postoperative complications: unconsciousness due to metabolic alkalosis caused by massive discharge from the gastrostomy and jaundice due to bile salt depletion caused by disruption of the enterohepatic circulation. His serum bilirubin levels decreased after the infusion of gastric discharge through gastrostomy into the transverse colon through the colostomy; thereafter, a second operation was performed to restore gastrointestinal continuity. Overall, patients undergoing massive bowel resection without intestinal continuity require careful management of electrolytes and bile salt.

Abstract
PURPOSE Because appendiceal diverticulitis (AD) has a high risk of perforation, precise diagnosis is important for patients with suspected acute appendicitis (AA). In this study, we aimed to reveal the characteristics of computed tomography (CT) images of AD. METHODS CT images were comparatively analyzed in patients who underwent appendectomy and had histopathologically proved AD (n = 23) or AA (n = 365) to reveal specific findings of CT image for AD and determine sensitivity and specificity of CT for AD. RESULTS Univariate analysis showed that maximal diameter of the appendix in AD was significantly smaller than that in AA. Multivariate analysis showed that saccular structure of the appendix wall, cecum or ascending colon diverticulum and peri-appendiceal or -cecal fluid collection were significant independent indicators of AD. Based on that saccular structure of the appendix wall which was the most important specific finding, the sensitivity and specificity of CT for AD were 48% and 99%, respectively. CONCLUSION The saccular structure of the appendix wall, cecum or ascending colon diverticulum and peri-appendiceal or -cecal fluid collection in CT suggest AD in patients with suspected AA. The sensitivity and specificity of CT for diagnosing AD were 48% and 99%, respectively.

Abstract
Abstract
Background
Although dobutamine stress echocardiography (DSE) at the early stage of acute myocardial infarction (AMI) is useful for the prediction of functional and clinical prognosis, the interpretation requires expertise. In this study, we sought to investigate if global longitudinal strain (GLS) during DSE after AMI can predict left ventricular remodeling (LVR).
Methods
Consecutive 30 patients with anterior wall AMI (18 male, age = 58 ± 13 years) were performed DSE 3 days after AMI. GLS was calculated as an averaged value of peak longitudinal strain in the apical 4- and 2-chamber views at baseline echocardiography, low-dose DSE (10 μg/kg/min) using available software (QLAB, Philips Medical Systems). Left ventricular remodeling (LVR) was defined as an echocardiographically determined increase in both EDVI and ESVI of 20% or more from baseline to the 6 month follow-up echocardiography.
Results
12 patients (40%) evolved with LVR. The change in GLS during low-dose DSE was significantly different between the remodeling and non-remodeling group (8 ± 5% v.s. 27 ± 20%, p < 0.05). Interestingly, it predicted LVR with sensitivity of 88%, specificity of 92% at the cut-off value of 12% (Area under the curve = 0.94, p < 0.0001).
Conclusion
The change in GLS during low-dose DSE can be used as a predictor for the LVR after AMI. This observation has promise for clinical applications.

Abstract
Background An inguinal hernia is a common disease; however, a malignant tumor within the inguinal hernia sac is rare, and perforated colon cancer in the hernia sac is extremely rare. Case presentation A 73-year-old man presented to our hospital with high fever and painful bulging of the lower abdomen. Computed tomography showed air-containing fluid in the abdominal wall, as well as localized wall thickness of the sigmoid colon in the left groin. An emergency operation revealed a huge subcutaneous abscess and a hard mass of the sigmoid colon within an indirect inguinal hernia sac. Sigmoidectomy and hernia repair using the Marcy method were performed. Lymph node dissection was performed through a transrectal abdominal incision. Histopathological examination of the resected specimen revealed moderately differentiated adenocarcinoma invading the serosal layer with lymph node metastasis. Conclusions Incarcerated inguinal hernia with perforated colon cancer is rare; an emergent operation should accordingly be performed based on infection control, oncological principles, and secure hernia repair.

Abstract
PURPOSE Several studies have analyzed late complications associated with totally implantable venous access ports (TIVAP) implantation via the internal jugular vein (IJV); however, the reported results are inconclusive. The aim of the study is to elucidate the characteristics and risk factors of late complications associated with TIVAP implantation via the IJV. METHODS The study included 482 patients who underwent TIVAP implantation for long-term chemotherapy and/or nutritional support between April 2012 and December 2017. Most patients (95.2%) had malignant diseases. Events requiring TIVAP removal were defined as TIVAP-related complications. RESULTS The median TIVAP and global follow-ups were 319 days (IQR 152-661) and 218,971 catheter days, respectively. The 3-year cumulative TIVAP availability rate was 70%. There were 44 complications (incidence of 9.1%; 0.201 complications/1000 catheter days). Infectious, catheter-related, and port-related complications occurred in 21, 14, and 9 patients, respectively with infectious complications occurring earlier and more frequently than catheter- and port-related complications. Multivariate analysis revealed that age < 65 years and presence of non-gastrointestinal diseases were significant unfavorable factors for TIVAP-related complications. Patients with 1 and 2 of these factors had an elevated risk (2.2 and 5.4 times, respectively) compared with those without. CONCLUSIONS Among the late complications associated with TIVAP implantation via the IJV, infectious complications occur earlier and more frequently than catheter- and port-related complications. Patients with an age < 65 years and having non-gastrointestinal diseases have a significantly high risk of TIVAP-related complications.

Abstract
Secretory IgA (SIgA) is a well-known mucosal-surface molecule in first-line defense against extrinsic pathogens and antigens. Its immunomodulatory and pathological roles have also been emphasized, but it is unclear whether it plays a pathological role in lung diseases. In the present study, we aimed to determine the distribution of IgA in idiopathic pulmonary fibrosis (IPF) lungs and whether IgA affects the functions of airway epithelial cells. We performed immunohistochemical analysis of lung sections from patients with IPF and found that mucus accumulated in the airspaces adjacent to the hyperplastic epithelia contained abundant SIgA. This was not true in the lungs of non-IPF subjects. An in-vitro assay revealed that SIgA bound to the surface of A549 cells and significantly promoted production of vascular endothelial growth factor (VEGF), transforming growth factor (TGF)-β and interleukin (IL)-8, important cytokines in the pathogenesis of IPF. Among the known receptors for IgA, A549 cells expressed high levels of transferrin receptor (TfR)/CD71. Transfection experiments with siRNA targeted against TfR/CD71 followed by stimulation with SIgA suggested that TfR/CD71 may be at least partially involved in the SIgA-induced cytokine production by A549 cells. These phenomena were specific for SIgA, distinct from IgG. SIgA may modulate the progression of IPF by enhancing synthesis of VEGF, TGF-β and IL-8.

Abstract
PURPOSE A growing body of evidence suggests that right-sided colorectal cancer (RCRC) differs from left-sided colorectal cancer (LCRC) in certain clinicopathological features. Therefore, we investigated the difference between RCRC and LCRC in a series of 899 patients. METHODS We reviewed data retrospectively, from 899 patients who underwent R0-resection for stage II and III CRC and compared the clinicopathological factors between patients with RCRC and LCRC. RESULTS The patients with RCRC tended to be older, more likely female, with a larger tumor, higher pathological T stage, and a greater proportion of their tumors were poorly differentiated adenocarcinoma, mucinous adenocarcinoma, or signet ring cell carcinoma than the patients with LCRC,. Recurrence-free survival (RFS) of the patients with RCRC tended to be higher than that of the patients with LCRC and was significantly better among patients with stage II cancer. The overall survival (OS) was similar for patients with RCRC and LCRC, irrespective of cancer stage. CONCLUSION Compared with the patients with LCRC, those with RCRC had several oncologically unfavorable factors, with better RFS in stage II and similar OS in stages II and III. These results suggest that the biological aggressiveness of RCRC is lower than that of LCRC in stage II; however, it can increase after relapse.

Abstract
Abstract
Background
The strategy of intravascular ultrasound (IVUS)-guided wiring for CTO PCI, that is, leading the second guidewire into the true lumen under observing by IVUS from subintimal space, is the last resort. We developed the angiography-based 3D wiring method. During establishment of the angiography-based 3D wiring method, we deduced that observation of the guidewire tip as well as the shaft named “The tip detection method” simplifies and facilitates 3D wiring under IVUS-guided wiring. Therefore, we produced New CTO IVUS which is the upgraded version of Navifocus WR IVUS by adding the pull-back transducer system. This pull-back system enables us to detect the tip as well as the shaft of the second guidewire in real time (tip detection method), which facilitates the 3D wiring technique under IVUS-guided wiring.
Objective
We evaluated the efficacy of the tip detection method during 3D wiring for CTO PCI with New CTO IVUS.
Method
We created a target pinpoint penetration model and performed the procedures using an experimental heartbeat model. The target (a tube with a lumen 0.6 mm in diameter) was placed in the distal part of a CTO 20 mm in length made of 2.5% agar. After the second guidewire (Conquest-12g) was advanced into the CTO lesion to within 5mm of the target using the angiography-based wiring, IVUS-guided wiring was performed by using Navifocus WR or New CTO IVUS each five times.
Result
The frequency of the puncture time was reduced using the new CTO IVUS compared to the Navifocus WR (1.7±0.8 vs. 28.8±23.2, p=0.17). The procedure time was significantly shorter using the new CTO IVUS compared to the Navifocus WR (103±61 vs. 459±373 seconds, p=0.04).
Conclusion
The tip detection method during 3D wiring with the new short tip IVUS with the pull-back system enables us to easily perform 3D wiring and will change the CTO PCI strategy.

Abstract
Abstract
Background
Sick sinus syndrome (SSS) and atrial fibrillation (AF) frequently coexist and interact to initiate and perpetuate each other. Several retrospective or small cohort studies have suggested that successful catheter ablation of AF may help to waive device implantations in patients with paroxysmal AF plus SSS, however, no prospective large studies are so far available on this scenario.
Purpose
We aimed to elucidate the device implantation-free survival after catheter ablation of paroxysmal AF with coexisting SSS in a prospective large-scale registry. We also determined the risk factors for device implantations after catheter ablation of paroxysmal AF.
Methods
The Kansai Plus Atrial Fibrillation (KPAF) study is a multi-center prospective registry that enrolled 5,019 consecutive patients that underwent an initial pulmonary vein isolation-based radiofrequency catheter ablation of AF. This study was comprised of 3,226 patients with paroxysmal AF registered in the KPAF study (age, 64.8±10.5 years old; female, n=999 [31.0%]; left atrial diameter [LAD], 37.5±8.0 mm; left ventricular ejection fraction [LVEF], 65.3±8.4%, CHADS2 score, 1.09±1.05). The atrial tachyarrhythmia-free and device-free survivals after catheter ablation were compared between patients with SSS (n=368; tachy-brady syndrome, 88%) and without SSS (control; n=2,858).
Results
The atrial tachyarrhythmia-free survival was almost identical between the two groups both after the first ablation session (Fig.1A) and after the last procedure with an average of 1.3±0.5 sessions. At baseline, the devices had already been implanted in 53 (14.4%) SSS and 36 (1.3%) control patients. In the remaining patients, devices were newly implanted in 54 (17.1%) SSS and 62 (2.2%) control patients during the follow-up of 3 years after the catheter ablation (Figure 1B). In the SSS group, devices were implanted predominantly within 6 months after the catheter ablation, and atrial tachyarrhythmia recurrence preceded the device implantation in 48 (89%) patients. Multivariate predictors of device implantations after the paroxysmal AF ablation included: SSS (hazard ratio [HR] 6.85, 95% confidence interval [CI] 4.61–10.19, p<0.001), an age>75 years old (HR 1.69, 95% CI 1.08–2.64, p=0.019), a female gender (HR 2.16, 95% CI 1.44–3.24, p<0.001), the LAD (mm) (HR 1.05, 95% CI 1.02–1.08, p=0.006), and the LVEF (%) (95% CI 0.96, 95% CI 0.94–0.98, p<0.001).
Figure 1
Conclusions
Device implantations could be waived in >80% of patients with SSS at 3 years of follow-up after the catheter ablation of paroxysmal AF in this real world all comer prospective registry. In addition to coexisting SSS, predictors of device implantations after paroxysmal AF ablation included: the elderly, a female gender, a large LA, and a reduced LVEF.

Abstract
SETTING The number of patients with non-tuberculous mycobacterial lung disease (NTM-LD) worldwide has been increasing. Mycobacterium avium complex lung disease (MAC-LD) accounts for 90% of NTM-LD. MAC-LD necessitates long-term treatment, but adverse reactions with long-term administration of drugs are poorly understood. OBJECTIVE To evaluate adverse reactions with long-term administration of drugs for MAC-LD. DESIGN We conducted a retrospective single-centre medical chart review of 364 patients administered two or more drugs between July 2010 and June 2015. RESULTS The prevalence and median time to onset of adverse reactions were as follows: hepatotoxicity 19.5%, 55 days; leucocytopaenia 20.0%, 41 days; thrombocytopaenia 28.6%, 61.5 days; cutaneous reactions 9.3%, 30 days; ocular toxicity 7.7%, 278 days; and increase in serum creatinine 12.4%, 430.5 days. Multivariate analysis showed that rifampicin use was independently associated with thrombocytopaenia, and ethambutol use was independently associated with increases in serum creatinine. CONCLUSION The main adverse reactions appeared within 3 months after start of treatment. Most patients were able to continue treatment with liver-supporting therapy, antihistamine agents or desensitisation therapy; however, ocular toxicity must be monitored for up to 1 year after start of treatment.

Abstract
Objectives To identify blood cell markers that predict the long-term outcomes of patients with colorectal cancer. Methods Data from 892 stage II and III colorectal cancer patients who underwent R0 resection were included. We analyzed the correlations of the preoperative blood data, previously reported prognostic indices, and clinicopathologic factors with the long-term outcomes, such as relapse-free survival and overall survival, using univariate and multivariate analyses. Results Multivariate analysis showed that tumor location, stage, mean corpuscular volume, neutrophil-to-lymphocyte ratio, and lymphocyte-to- monocyte ratio were significantly correlated with relapse-free survival. A mean corpuscular volume ≥80.5 fL, neutrophil-to-lymphocyte ratio ≥5.5, and lymphocyte-to- monocyte ratio <3.4 had hazard ratios for disease relapse between 1.39 and 1.93. The cumulative scores of these three factors were aggregated into a laboratory prognostic score, with a maximum score at 6. The relapse-free survival and overall survival were well stratified by a laboratory prognostic score between 0–3 and 4–6, respectively, independent of the stage. Conclusion The mean corpuscular volume, neutrophil-to-lymphocyte ratio, and lymphocyte-to- monocyte ratio can serve as blood cell markers to predict the long-term outcomes of patients who underwent R0 resection for stage II/III colorectal cancer.

Abstract
The diagnosis of malignant tumors during pregnancy is not uncommon; the incidence is one per six thousand pregnancies. However, the diagnosis of malignant lymphoma-especially T-cell lymphoma-during pregnancy is extremely rare. Thus, the early detection and management of T-cell lymphoma necessitates difficult decision-making. A 30-year-old woman developed consciousness disturbance on postpartum day three. Because brain MRI showed multiple edematous lesions in both hemispheres, vasculitis or encephalitis was initially suspected, and diagnostic therapy was initiated with the administration of steroids. One month later, the patient suddenly developed a subarachnoid hemorrhage followed by acute hydrocephalus. Emergent ventricular drainage and lesion biopsy were simultaneously performed. Based on the findings, the patient was diagnosed with peripheral T-cell lymphoma not otherwise specified(PTCL-NOS). Laboratory findings indicated Epstein-Barr virus(EBV)infection. Moreover, the same diagnosis was supported by breast and bone marrow biopsies. Thus, the brain lesions were presumed to be metastatic in nature. The prognosis of PTCL-NOS is severely poor in pregnant women as diagnosis is delayed owing to limitations of radiological examinations and because symptoms can be confused with those of other diseases or hyperemesis gravidarum. Additionally, the alteration of immunotolerance in association with pregnancy and EBV infection might have influenced the aggressive features of this case. When a pregnant woman presents with neurological symptoms, malignant lymphoma should be considered when making a differential diagnosis.

Abstract
Splenic cysts are rare and tend to have elevated tumor markers, of which carbohydrate antigen (CA) 19-9 is the most frequently elevated. Therefore, splenic cysts with elevated serum carcinoembryonic antigen (CEA) levels and without CA19-9 elevation are extremely rare. A 26-year-old woman presented with sudden upper abdominal pain while sleeping. Contrast-enhanced computed tomography (CT) showed an 85-mm simple splenic cyst in the upper pole and a moderate amount of ascites around the spleen. The serum levels of CEA, but not CA19-9, were elevated. Spontaneous rupture of a splenic cyst was diagnosed. We performed elective laparoscopic unroofing. The histological findings revealed a stratified squamous epithelium on the inner surface of the cystic wall. On immunohistochemical examination, the squamous epithelium was found to be positive for cytokeratin (CK)7, negative for calretinin, and positive for CEA. The histological diagnosis was an epidermoid cyst. Three months after the operation, the elevated serum tumor marker levels of CEA were normalized. Splenic cysts with high levels of CEA and low levels of CA19-9 are extremely rare. Laparoscopic unroofing is a useful operative procedure for ruptured splenic cysts with elevated levels of serum tumor markers.

Abstract
Immunoglobulin (Ig)A is the most abundant immunoglobulin in humans, and in the airway mucosa secretory IgA (sIgA) plays a pivotal role in first-line defense against invading pathogens and antigens. IgA has been reported to also have pathogenic effects, including possible worsening of the prognosis of idiopathic pulmonary fibrosis (IPF). However, the precise effects of IgA on lung fibroblasts remain unclear, and we aimed to elucidate how IgA activates human lung fibroblasts. We found that sIgA, but not monomeric IgA (mIgA), induced interleukin (IL)-6, IL-8, monocyte chemoattractant protein (MCP)-1 and granulocyte-macrophage colony-stimulating factor (GM-CSF) production by normal human lung fibroblasts (NHLFs) at both the protein and mRNA levels. sIgA also promoted proliferation of NHLFs and collagen gel contraction comparable to with transforming growth factor (TGF)-β, which is involved in fibrogenesis in IPF. Also, Western blot analysis and real-time quantitative polymerase chain reaction (PCR) revealed that sIgA enhanced production of α-smooth muscle actin (α-SMA) and collagen type I (Col I) by NHLFs. Flow cytometry showed that NHLFs bound sIgA, and among the known IgA receptors, NHLFs significantly expressed CD71 (transferrin receptor). Transfection of siRNA targeting CD71 partially but significantly suppressed cytokine production by NHLFs co-cultured with sIgA. Our findings suggest that sIgA may promote human lung inflammation and fibrosis by enhancing production of inflammatory or fibrogenic cytokines as well as extracellular matrix, inducing fibroblast differentiation into myofibroblasts and promoting human lung fibroblast proliferation. sIgA's enhancement of cytokine production may be due partially to its binding to CD71 or the secretory component.

Abstract
The basic properties of a Talbot interferometer implementing pinhole arrays were experimentally and numerically investigated for the improvement of measurement sensitivity of laser wavefront sensors utilized for electron density imaging over discharge plasmas. A numerical simulation using a plane wave decomposition method indicated that the pinhole arrays with a pitch of 300 μm and a pinhole diameter of 150 μm were most suitable for the measurement of the millimetre-scale discharge plasmas, in consideration of the spatial resolution and measurement accuracy. The plane wave decomposition simulation expected that the measurement sensitivity of the 8th-Talbot-length interferometer could be improved by a factor of 4 compared with the previously developed Shack-Hartmann type laser wavefront sensors, which was experimentally verified by the self-image behavior of the pinhole arrays. The Talbot interferometric system was successfully used for electron density imaging over the vacuum arcs generated between a 3-mm gap. The electron density image observed by the Talbot interferometers was in excellent agreement with that visualized by the previously developed Shack-Hartmann sensors. The practical notification for the pinhole array fabrication was also presented.

Abstract
Distributions of radiocaesium (134Cs and 137Cs) derived from the Tokyo Electric Power Company (TEPCO) Fukushima Dai-ichi Nuclear Power Plant (FNPP1) accident in the North Pacific Ocean in the summer of 2012 were investigated. We have estimated the radiocaesium inventory in the surface layer using the optimal interpolation analysis and the subducted amount into the central mode water (CMW) by using vertical profiles of FNPP1-134Cs and mass balance analysis as the first approach. The inventory of the 134Cs in the surface layer in the North Pacific Ocean in August-December 2012 was estimated at 5.1 ± 0.9 PBq on 1 October 2012, which corresponds to 8.6 ± 1.5 PBq when it was decay corrected to the date of the FNPP1 accident, 11 March 2011. It was revealed that 56 ± 10% of the released 134Cs into the North Pacific Ocean, which was estimated at 15.3 ± 2.6 PBq, transported eastward in the surface layer in 2012. The amount of 134Cs subducted in the CMW was estimated to be 2.5 ± 0.9 PBq based on the mass balance among the three domains of the surface layer, subtropical mode water, and CMW.

Abstract
MIB-1 is a cell proliferation marker and has previously been investigated as a diagnostic or prognostic indicator of malignancy. Previous studies have investigated MIB-1 index and clinicopathological factors in relation to prognosis of patients with esophageal cancer, with conflicting results. The aim of this study is to assess the prognostic significance of MIB-1 index in patients with thoracic esophageal squamous cell carcinoma. A total of 78 patients who underwent R0-esophagectomy for thoracic esophageal squamous cell carcinoma were enrolled in this study. Preoperatively, 29 patients underwent chemotherapy, six underwent chemoradiotherapy, and the remaining did not undergo any preoperative therapy. The MIB-1 labeling index was reported by counting 500 tumor cells in the hot spots of nuclear labeling. Correlations between MIB-1 index, clinicopathological factors, and relapse-free survival (RFS) were investigated. The mean MIB-1 index was 39.3 ± 21.0 (range: 0-91.3). There was no significant correlation between clinicopathological factors and MIB-1 index in the study patients, irrespective of whether they underwent preoperative therapy. Univariate analysis revealed no significant association between MIB-1 index and RFS. However, depth of tumor invasion, lymph node metastasis and stage, all showed a significant correlation to RFS. Multivariate analysis of RFS revealed that stage was the only significant factor. Conversely, MIB-1 index was not significantly related to RFS (p = 0.41). In conclusion, MIB-1 index is unlikely to be a significant prognostic indicator for esophageal cancer.

Abstract
High molecular weight neutrophil chemotactic activity has been identified in resected human nasal polyps, inferior turbinates, and nasal secretions following antigen challenge. The estimated molecular weight, by gel filtration chromatography, was approximately 600,000. However, a heterogeneity of molecular weight in some patients was recognized. Our results suggest a possible role for high molecular weight-neutrophil chemotactic activity in the pathogenesis of hypersensitivity in the human nasal cavity.
