Anastomotic leakage (AL) following low anterior resection (LAR) for rectal cancer is a major complication. While most reports focus on the closure of AL using over-the-scope clip (OTSC), few reports are available on the use of through-the-scope clip (TTSC). This is because TTSC is not typically designed for full-thickness closure, unlike OTSC. However, a MANTIS clip, categorized as TTSC, is indicated for full-thickness closure. A 73-year-old man diagnosed with AL 7 days postoperatively following laparoscopic LAR underwent laparoscopic drainage and ileostomy the next day. Although the drainage led to the shrinkage of the fistula, it persisted even after 2 months. Consequently, the fistula orifice was closed using a MANTIS clip under colonoscopy and radiography. Two days later, the patient was discharged. The drain was withdrawn cautiously to prevent residual fistula and removed completely on day 29. This report highlights our experience in using a MANTIS clip for AL following LAR., Competing Interests: None declared., (Published by Oxford University Press and JSCR Publishing Ltd. © The Author(s) 2024.)

Objectives: The aging population, including patients with superficial esophageal cancer, encounters critical dysphagia- and postoperative pneumonia-related issues. Although endoscopic submucosal dissection (ESD) provides advantages over other modalities, older patients are at higher risk of postoperative pneumonia. Furthermore, the etiologies of pneumonia are complex and include patient- (such as sarcopenia) and treatment- (including ESD) related factors. Therefore, this study evaluated swallowing function in patients with superficial esophageal cancer and identified post-ESD pneumonia-associated factors., Methods: Comprehensive swallowing function and sarcopenia were evaluated in patients pre-ESD and 2 months post-ESD using high-resolution manometry and several swallowing studies by multiple experts. The effects of mucosal resection and sarcopenia on swallowing function changes post-ESD, the relationship between preoperative swallowing function and sarcopenia, and the factors influencing postoperative pneumonia were investigated., Results: Twenty patients were included in the study. Patients with preoperative sarcopenia had significantly lower pharyngeal/upper esophageal sphincter and tongue pressures than those without sarcopenia. However, ESD did not worsen pharyngeal or upper esophageal pressure. Post-ESD pneumonia incidence tended to be higher in patients with sarcopenia than in those without sarcopenia. The lower upper esophageal sphincter-integrated relaxation pressure (UES-IRP) was a significant factor in pneumonia development. Furthermore, the receiver operating characteristic curve for UES-IRP in pneumonia yielded an area under the curve of 0.82., Conclusions: Sarcopenia is associated with preoperative dysphagia, which increases post-ESD pneumonia risk. Therefore, postoperative pneumonia incidence is expected to increase with an aging population, making preoperative sarcopenia and swallowing function evaluation crucial., (© 2023 Japan Gastroenterological Endoscopy Society.)

Frailty is highly prevalent among patients with aortic stenosis (AS). Nonetheless, the impact of AS severity on frailty remains unclear. This study aimed to clarify the association between AS severity and frailty in this population.This retrospective study included consecutive patients with AS who were hospitalized as candidates for transcatheter aortic valve implantation (TAVI). The prevalence of frailty, N-terminal pro B-type natriuretic peptide (NT-proBNP) level, gait speed, and geriatric nutritional risk index (GNRI) were compared between patients with severe and those with very severe AS. We employed multiple logistic regression analysis to examine the association between AS severity and frailty.A total of 137 patients were included. The prevalence of frailty was not significantly different between the severe and very severe AS groups (31% versus 30%). Similarly, no significant differences between the groups were observed for gait speed and GNRI, whereas the NT-proBNP level was significantly higher in the very severe group than in the severe AS group (P < 0.01). In the multiple logistic regression analysis, AS severity was not associated with frailty; however, gait speed and GNRI showed significant association with frailty independently of age, sex, and heart failure (very severe AS: odds ratio [OR] 1.051, 95% confidence interval [CI] 0.439-2.517; low gait speed: OR 5.109, 95% CI 1.556-16.775; malnutrition: OR 2.841, 95% CI 1.145-7.049).These findings suggest that low-intensity exercise training and nutritional therapy may be necessary in addition to AS treatment for the management of frailty in this population.

Bronchoscopy is a common diagnostic procedure used to identify lung cancer. Specimens acquired through transbronchial biopsy are pivotal in the diagnosis and molecular characterization of this disease. The occurrence of benign mesothelial cells during a transbronchial biopsy (TBB) is relatively rare. Furthermore, these lesions can sometimes be erroneously identified as malignant, potentially resulting in unwarranted or inappropriate treatment for patients with and without lung cancer. In this retrospective analysis, we examined 619 TBB cases at our institute from 2019 to 2021. Benign mesothelial cells were identified via immunohistochemical studies in eight (1.3%) of 619 cases. These cells were classified into three patterns based on their cellular morphology: monolayer, lace, and cobblestone. Recognizing this phenomenon during the procedure is crucial to accurately distinguish benign mesothelial cells from their cancerous counterparts., (Copyright © 2023 Elsevier GmbH.

This study aimed to examine the validity of urinary N-terminal titin fragment/creatinine (urinary N-titin/Cr) reflecting muscle damage biomarker in patients with interstitial lung disease. This retrospective study enrolled patients with interstitial lung disease. We measured urinary N-titin/Cr. Furthermore, we measured the cross-sectional areas of the pectoralis muscles above the aortic arch (PM CSA ) and erector spinae muscles of the 12th thoracic vertebra muscles (ESM CSA ) to assess muscle mass until 1 year. We examined the correlation between urinary N-titin/Cr and the change in muscle mass. We plotted receiver operating characteristic curves to estimate the cut-off points for urinary N-titin/Cr for distinguishing the greater-than-median and smaller-than-median reduction of muscle mass after 1 year. We enrolled 68 patients with interstitial lung disease. The median urinary N-titin/Cr value was 7.0 pmol/mg/dL. We observed significant negative correlations between urinary N-titin/Cr and changes in the PM CSA after 1 year (p < 0.001) and changes in the ESM CSA after 6 months (p < 0.001) and 1 year (p < 0.001). The cut-off points for urinary N-titin/Cr were 5.2 pmol/mg/dL and 10.4 pmol/mg/dL in the PM CSA and ESM CSA , respectively. In summary, urinary N-titin/Cr may predict muscle loss in the long-term and act as a clinically useful biomarker reflecting muscle damage., (© 2023. The Author(s).)

Background: Hospital-acquired disability (HAD) in patients who undergo living donor liver transplantation (LDLT) is expected to worsen physical functions due to inactivity during hospitalization. The aim of this study was to explore whether a decline in activities of daily living from hospital admission to discharge is associated with prognosis in LDLT patients, who once discharged from a hospital., Methods: We retrospectively examined the relationship between HAD and prognosis in 135 patients who underwent LDLT from June 2008 to June 2018, and discharged from hospital once. HAD was defined as a decline of over 5 points in the Barthel Index as an activity of daily living assessment. Additionally, LDLT patients were classified into four groups: low or high skeletal muscle index (SMI) and HAD or non-HAD. Univariate and multivariate Cox proportional hazard models were used to evaluate the association between HAD and survival., Results: HAD was identified in 47 LDLT patients (34.8%). The HAD group had a significantly higher all-cause mortality than the non-HAD group (log-rank: p < 0.001), and in the HAD/low SMI group, all-cause mortality was highest between the groups (log-rank: p < 0.001). In multivariable analysis, HAD was an independent risk factor for all-cause mortality (hazard ratio [HR]: 16.54; P < 0.001) and HAD/low SMI group (HR: 16.82; P = 0.002)., Conclusion: HAD was identified as an independent risk factor for all-cause mortality suggesting that it could be a key component in determining prognosis after LDLT. Future larger-scale studies are needed to consider the overall new strategy of perioperative rehabilitation, including enhancement of preoperative physiotherapy programs to improve physical function., (© 2022.

We conducted a cross-sectional study using a structured questionnaire in three major Japanese cities from August 03 to 24, 2020 to clarify the current situation of health checkups, including vaccine-preventable diseases (VPDs), among international students at Japanese universities (JUs) and Japanese language schools (JLSs). The total response rate was 36%: 69 JUs (31%) and 137 JLSs (39%). Over 90% of these institutions conducted chest X-ray screening for tuberculosis among their students, whereas only 24.6% of JUs and 15.3% of JLSs performed general blood tests for health screening. Only 14.5% and 2.2% of the JUs and JLSs, respectively, required the submission of vaccination or antibody certificates for admission. The difficulties in requesting vaccination certificates from international students are due to poor legal requirements and concerns about rising costs for schools. From 2017 to 2019, 183 international students, principally from East Asia and Southeast Asia, were infected with VPDs, particularly tuberculosis (99 cases) and varicella (71 cases). Whereas the majority of Japanese educational institutions screen international students for tuberculosis (TB) at admission, only a few institutions request proof of antibody testing relating to other VPDs or of vaccination. These findings will help formulate guidelines for checkups related to vaccination for international students required to protect the educational institutions in Japan from the spread of VPDs. In addition, providing multifaceted social support, including financial compensation for institutions and enhanced international students' health issues, would be helpful.

Background: The Asian Working Group for Sarcopenia 2019 (AWGS 2019) is the gold standard diagnostic criteria for sarcopenia in Asian populations. The calf circumference (CalF), the strength, assistance in walking, rising from a chair, climbing stairs, and falls (SARC-F) and the SARC-CalF questionnaires for sarcopenia screening have been used by AWGS 2019. The aim of this study was to assess accuracy of these three sarcopenia screening tools in patients with interstitial lung disease., Methods: In this cross-sectional study, stable patients with interstitial lung disease were enrolled. The SARC-F, SARC-CalF, and CalF, used in patients with interstitial lung disease, were compared to the diagnostic criteria proposed by AWGS 2019. The accuracy of screening tools was compared using sensitivity and specificity. Moreover, areas under the receiver operating characteristic curves (AUC) were computed., Results: Seventy eight patients were analyzed, and sarcopenia was identified in 25 (32.1%) patients with interstitial lung disease by the AWGS 2019 criteria. The sensitivity of the CalF was highest (96%) of the three screening tools, while the specificity was 60%. The sensitivity of SARC-F and SARC-CalF were 24% and 68%, while the specificity were 92% and 66%, respectively. The AUCs of CalF, SARC-F, and SARC-CalF in all patients were 0.78, 0.58, and 0.67, respectively., Conclusions: The CalF is most suitable for screening sarcopenia in patients with interstitial lung disease, while SARC-F and SARC-CalF are not., (© 2022.
