RESUMO
The patient was a 35-year-old man who saw his first doctor with the chief complaint of painful urination. A contrast- enhanced CT scan of the abdomen revealed a diagnosis of abscess-forming appendicitis with inflammatory spread to the bladder, and conservative treatment was decided. Since antibiotic treatment failed to reduce the size of the abscess, he underwent surgery. The bladder wall was highly inflamed, only appendectomy was performed. Pathology revealed appendiceal mucinous carcinoma invading the bladder, so he was referred to our department. Because a total cystectomy was required for curative resection and there was concern about seeding associated with the initial surgery, he was judged to be unresectable, and received chemotherapy. After 6 courses of CAPOX+bevacizumab therapy, he was able to have a bladder- sparing curative resection because of the absence of distant metastasis and shrinkage of the tumor. He remains stable without recurrence 6 months after surgery. We herein report, with some discussion of the literature, this case of bladder-invading appendiceal mucinous carcinoma arising from abscess-forming appendicitis, for which a curative resection was possible after chemotherapy.

BACKGROUND: The diagnostic criteria for lateral lymph node metastasis in rectal cancer have not been established. This research aimed to investigate the risk factors for lateral lymph node metastasis and develop machine learning models combining these risk factors to improve the diagnostic performance of standard imaging. METHOD: This multicentre prospective study included patients who underwent lateral lymph node dissection without preoperative treatment for rectal cancer between 2017 and 2019 in 15 Japanese institutions. First, preoperative clinicopathological factors and magnetic resonance imaging findings were evaluated using multivariable analyses for their correlation with lateral lymph node metastasis. Next, machine learning diagnostic models for lateral lymph node metastasis were developed combining these risk factors. The models were tested in a training set and in an internal validation cohort and their diagnostic performance was tested using receiver operating characteristic curve analyses. RESULTS: Of 212 rectal cancers, 122 patients were selected, including 232 lateral pelvic sides, 30 sides of which had pathological lateral lymph node metastasis. Multivariable analysis revealed that poorly differentiated/mucinous adenocarcinoma, extramural vascular invasion, tumour deposit and a short-axis diameter of lateral lymph node ≥ 6.0 mm were independent risk factors for lateral lymph node metastasis. Patients were randomly divided into a training cohort (139 sides) and a test cohort (93 sides) and machine learning models were computed on the basis of a combination of significant features (including: histological type, extramural vascular invasion, tumour deposit, short- and long-axis diameter of lateral lymph node, body mass index, serum carcinoembryonic antigen level, cT, cN, cM, irregular border and mixed signal intensity). The top three models with the highest sensitivity in the training cohort were as follows: support vector machine (sensitivity, 1.000; specificity, 0.773), light gradient boosting machine (sensitivity, 0.950; specificity, 0.918) and ensemble learning (sensitivity, 0.950; specificity, 0.917). The diagnostic performances of these models in the test cohort were as follows: support vector machine (sensitivity, 0.750; specificity, 0.667), light gradient boosting machine (sensitivity, 0.500; specificity, 0.852) and ensemble learning (sensitivity, 0.667; specificity, 0.864). CONCLUSION: Machine learning models combining multiple risk factors can contribute to improving diagnostic performance of lateral lymph node metastasis.

Nicotinamide adenine dinucleotide (NAD +) plays a pivotal role in numerous cellular functions. Reduced NAD + levels are postulated to be associated with cancer. As interest in understanding NAD + dynamics in cancer patients with therapeutic applications in mind grows, there remains a shortage of comprehensive data. This study delves into NAD + dynamics in patients undergoing surgery for different digestive system cancers. This prospective study enrolled 99 patients with eight different cancers. Fasting blood samples were obtained during the perioperative period. The concentrations of NAD + , nicotinamide mononucleotide (NMN), and nicotinamide riboside were analyzed using tandem mass spectrometry. After erythrocyte volume adjustment, NAD + remained relatively stable after surgery. Meanwhile, NMN decreased the day after surgery and displayed a recovery trend. Interestingly, liver and pancreatic cancer patients exhibited poor postoperative NMN recovery, suggesting a potential cancer type-specific influence on NAD + metabolism. This study illuminated the behavior of NAD + in surgically treated cancer patients. We identified which cancer types have particularly low levels and at what point depletion occurs during the perioperative period. These insights suggest the need for personalized NAD + supplementation strategies, calibrated to individual patient needs and treatment timelines. Clinical trial registration jRCT1020210066.

STUDY DESIGN: This is a prospective cohort study. PURPOSE: The present study aimed to investigate the effects of residual pain after fusion surgery for lumbar degenerative diseases on quality of life (QOL). OVERVIEW OF LITERATURE: Residual symptoms after spinal surgery often restrict patients' activities of daily living and reduce their QOL. However, few studies have comprehensively addressed physical, psychological, and social factors. METHODS: The study population included a cohort of 208 patients (mean age: 67.9 years) who had undergone posterior interbody fusion for lumbar degenerative disease between 2012 and 2019. We asked the patients to complete the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) and Short Form Health Survey (SF-36) preoperatively, as well as at six, 12, and 24 months postoperatively. The presence of residual postoperative pain (RPP) was determined using the low back pain score of the JOABPEQ at six months postoperatively, and patients with an improvement of < 20 points compared to preoperative assessment were classified as RPP+ based on a previous study. RESULTS: In all patients, there was a notable postoperative improvement in all JOABPEQ and SF-36 domains compared to preoperative scores. The RPP+ group comprised 60 patients (69.6 years), while the RPP- group comprised 148 patients (67.2 years). In the RPP+ group, the lumbar function in the JOABPEQ and general health in the SF-36 showed limited postoperative enhancement. The pace of improvement in the role-emotional, role-physical, social functioning, vitality, and mental health scores was slower in the RPP+ group compared to the RPP- group. CONCLUSIONS: In the current study, we found that the presence of residual pain at six months postoperatively affected QOL improvement up to 24 months after surgery. Lingering postoperative pain substantially impacted functional incapacity, social engagement, and psychological well-being. Notably, the lumbar function in the JOABPEQ and general health in the SF-36 showed distinct progression patterns in the RPP+ group.
RESUMO
PURPOSE: The purpose of the present study was to investigate the association between quantitatively assessed trunk extensor strength and gait-induced back pain (GIBP) in patients with adult spinal deformity (ASD). METHODS: Ninety-five patients with ASD aged ≥ 50 years who were admitted to our hospital between April 2018 and March 2023 were included in the study. GIBP was evaluated through a 6-minute walking test (6MWT), with GIBP being defined as the occurrence of back pain during the evaluation and inability to complete the test. The patients were divided into three groups: difficulty completing the 6MWT (Group 1), ability to complete the 6MWT with breaks (Group 2), and ability to complete the 6MWT without taking a break (Group 3). The main independent variable was trunk extensor strength, which was measured using a hand-held dynamometer. Ordered logistic regression analysis was conducted to assess the association between GIBP and trunk extensor strength while adjusting for basic characteristics and radiographic parameters as covariates. RESULTS: The numbers of patients with ASD included in each group were; 27 in Group 1 (28.4%), 31 in Group 2 (32.6%), and 37 in Group 3 (39.0%). An ordered logistic regression analysis adjusted for basic characteristics and radiographic parameters, trunk extensor strength was significantly associated with GIBP (odds ratios, 1.128; 95% confidence intervals, 1.025-1.242). CONCLUSIONS: The results of the present study strongly indicate that trunk extensor strength is a valuable factor associated with GIBP in patients with ASD.

A 52-year-old woman with Marfan syndrome developed Stanford type B aortic dissection and was treated with thoracic endovascular aortic repair. However, 29 months later, she presented with retrograde Stanford type A aortic dissection. We successfully performed aortic arch replacement with the frozen elephant trunk technique and valve-sparing aortic root replacement. The advantages of the frozen elephant trunk technique are that the distal anastomosis can be created without stent-graft resection and the cardiac arrest time is shortened. Therefore, the frozen elephant trunk technique was considered valuable and safe in this potentially lethal situation.

Aim: We report the short/mid-term results of surgery for high-risk locally advanced rectal cancer (LARC) after neoadjuvant chemotherapy (NAC, four courses of S-1 + oxaliplatin+ bevacizumab) without radiotherapy with the primary aim of ypT0-2. Methods: High-risk LARC was defined as cT4b, mesorectal fascia (MRF) ≤1 mm (MRF+), or lateral lymph node metastasis (cLLN+) on high-resolution MRI. The planned 32 cases from April 2018 to December 2021 were all included. Results: There were 10 patients at cT4b (31.2%), 26 MRF+ (81.3%), and 22 cLLN+ (68.8%). Thirteen (40.6%) underwent NAC after a colostomy for stenosis. NAC was completed in 26 (81.2%) cases. Grade 3 or higher adverse events occurred in six (18.7%). One patient developed progressive disease (3.2%). Eleven were ycT0-3MRF-LLN- (34.3%). Curative-intent surgery was performed on 31, with sphincter-preserving surgery in 20, abdominoperineal resection in nine, total pelvic exenteration in two, and lateral lymph node dissection in 24. Two had R1/2 resection (6.4%). A Grade 3 or higher postoperative complication rate occurred in 3.2%. Pathological complete response and ypT0-2 rates were 12.9% and 45.1%. Three-year disease-free survival rates (3yDFS) for ypT0-2 and ypT ≥3 were 81.2%, 46.6% (p = 0.061), and 3-year local recurrence rates (3yLR) were 0%, 48.8% (p = 0.015). 3yDFS for ycT0-3MRF-LLN- and ycT4/MRF+/LLN+ were 87.5%, 48.0% (p = 0.031) and 3yLR were 0%, 42.8% (p = 0.045). Conclusion: NAC yielded a clinically significant effect in about half of high-risk LARC patients. If NAC alone is ineffective, radiotherapy should be added, even if extended surgery is intended.
RESUMO
BACKGROUNDS: Evaluation of gait posture using a three-dimensional motion analysis system (3DMAS) revealed that elderly patients with adult spinal deformity (ASD) experience pelvic anteversion while walking. The purpose of this study was to investigate the influence of changes in pelvic anteversion during gait on walking ability and physical function in patients with ASD. METHODS: Fifty-four patients with ASD aged 50 years or older who were admitted to our hospital between March 2016 and December 2021 were included in the study. The 6-min walking distance (6MWD) was used to evaluate walking ability, and trunk and hip extensor strength were measured to evaluate physical function in the subjects. The 3DMAS was used to measure the subject's changes in pelvic anteversion during gait. After measuring the changes in pelvic anteversion, the median value of the study subjects was calculated, according to which the subjects were divided into two groups (small anteversion [S] group, large anteversion [L] group). Walking ability and physical function were compared between the two groups. RESULTS: The number of subjects in each group was 27. Comparisons of walking ability and physical function between the groups revealed significant differences in 6MWD (S group, 333.6 ± 111.2 m; L group, 238.0 ± 106.3 m) and hip extensor strength (S group, 15.8 ± 3.8 kgf; L group, 13.4 ± 4.4 kgf). No significant differences regarding trunk extensor strength were observed between the groups (S group, 15.2 ± 4.0 kgf; L group, 12.9 ± 4.8 kgf). CONCLUSION: The results of the present study revealed that ASD patients with greater pelvic anteversion associated with walking have lower walking ability and physical function. These results suggest the importance of evaluating the posture of ASD patients not only by using radiographic findings but also by assessing movement, such as gait posture.
RESUMO
BACKGROUND: Extramural vascular invasion (EMVI) and tumor deposits (TD) are poor prognostic factors in rectal cancer (RC), especially when resistant to neoadjuvant chemotherapy (NAC). We aimed to define differential expression in NAC responders and non-responders with concomitant EMVI and TD. METHODS: From 52 RC surgical patients, post-NAC resected specimens were extracted, comprising two groups: cases with residual EMVI and TD (NAC-resistant) and cases without (NAC-effective). Proteomic analysis was conducted to define differential protein expression in the two groups. To validate the findings, immunohistochemistry was performed in another cohort that included 58 RC surgical patients. Based on the findings, chemosensitivity and prognosis were compared. RESULTS: The NAC-resistant group was associated with a lower 3-year disease-free survival rate than the NAC-effective group (p = 0.041). Discriminative proteins in the NAC-resistant group were highly associated with the sulfur metabolism pathway. Among these pathway constituents, selenium-binding protein 1 (SELENBP1) expression in the NAC-resistant group decreased to less than one-third of that of the NAC-effective group. Immunohistochemistry in another RC cohort consistently validated the relationship between decreased SELENBP1 and poorer NAC sensitivity, in both pre-NAC biopsy and post-NAC surgery specimens. Furthermore, decrease in SELENBP1 was associated with a lower 3-year disease-free survival rate (p = 0.047). CONCLUSIONS: We defined one of the differentially expressed proteins in NAC responders and non-responders, concomitant with EMVI and TD. SELENBP1 was suspected to contribute to NAC resistance and poor prognosis in RC.

INTRODUCTION: Static spine and pelvic posture has been reported to be associated with symptoms in patients with lumbar spinal stenosis (LSS), but it is unknown whether dynamic alignment of the spine and pelvis is associated with lumbar function in daily life. This study aims to investigate the relationship between dynamic alignment of the spine and pelvis during gait and lumbar function in daily life in patients with LSS. METHODS: We evaluated lumbar function in daily life using the Oswestry Disability Index (ODI), trunk and hip muscle strength as physical function, static spinal alignment, and dynamic spinal/pelvic alignment during gait. The relationship between the ODI score and physical function or static and dynamic alignment was examined. RESULTS: A total of 35 preoperative patients with LSS participated in this study. ODI score significantly correlated with trunk extension strength (r = -0.578, p = 0.000), hip extension strength (r = -0.472, p = 0.004), maximum spinal flexion angle during gait (r = -0.473, p = 0.004) and maximum pelvic anterior tilt angle (r = 0.510, p = 0.002). Multiple regression analysis showed that trunk extension strength (standardized ß; - 0.309), hip extension strength (standardized ß; -0.287), maximum spinal flexion angle (standardized ß; - 0.306) and maximum pelvic anterior tilt angle (standardized ß; 0.271) significantly affected the ODI score, with adjusted coefficient of determination of 0.529. CONCLUSION: The results of this study showed that the patients with LSS with weak hip or trunk extensor muscles, a greater angle of pelvic tilt or a less spinal flexion during gait had a lower lumbar function in daily life.

BACKGROUND: Metastatic lateral lymph node dissection can improve survival in patients with rectal adenocarcinoma, with or without chemoradiotherapy. However, the optimal imaging diagnostic criteria for lateral lymph node metastases remain undetermined. OBJECTIVE: To develop a lateral lymph node metastasis diagnostic artificial intelligence tool using deep learning, for patients with rectal adenocarcinoma who underwent radical surgery and lateral lymph node dissection. DESIGN: Retrospective study. SETTINGS: Multicenter study. PATIENTS: A total of 209 patients with rectal adenocarcinoma, who underwent radical surgery and lateral lymph node dissection at 15 participating hospitals, were enrolled in the study and allocated to training (n = 139), test (n = 17), or validation (n = 53) cohorts. MAIN OUTCOME MEASURES: In the neoadjuvant treatment group, images taken before pretreatment were classified as baseline images and those taken after pretreatment as presurgery images. In the upfront surgery group, presurgery images were classified as both baseline and presurgery images. We constructed 2 types of artificial intelligence, using baseline and presurgery images, by inputting the patches from these images into ResNet-18, and we assessed their diagnostic accuracy. RESULTS: Overall, 124 patients underwent surgery alone, 52 received neoadjuvant chemotherapy, and 33 received chemoradiotherapy. The number of resected lateral lymph nodes in the training, test, and validation cohorts was 2418, 279, and 850, respectively. The metastatic rates were 2.8%, 0.7%, and 3.7%, respectively. In the validation cohort, the precision-recall area under the curve was 0.870 and 0.963 for the baseline and presurgery images, respectively. Although both baseline and presurgery images provided good accuracy for diagnosing lateral lymph node metastases, the accuracy of presurgery images was better than that of baseline images. LIMITATIONS: The number of cases is small. CONCLUSIONS: An artificial intelligence tool is a promising tool for diagnosing lateral lymph node metastasis with high accuracy. DESARROLLO DE UNA HERRAMIENTA DE INTELIGENCIA ARTIFICIAL PARA EL DIAGNSTICO DE METSTASIS EN GANGLIOS LINFTICOS LATERALES EN CNCER DE RECTO AVANZADO: ANTECEDENTES:Disección de nódulos linfáticos laterales metastásicos puede mejorar la supervivencia en pacientes con adenocarcinoma del recto, con o sin quimiorradioterapia. Sin embargo, aún no se han determinado los criterios óptimos de diagnóstico por imágenes de los nódulos linfáticos laterales metastásicos.OBJETIVO:Nuestro objetivo fue desarrollar una herramienta de inteligencia artificial para el diagnóstico de metástasis en nódulos linfáticos laterales mediante el aprendizaje profundo, para pacientes con adenocarcinoma del recto que se sometieron a cirugía radical y disección de nódulos linfáticos laterales.DISEÑO:Estudio retrospectivo.AJUSTES:Estudio multicéntrico.PACIENTES:Un total de 209 pacientes con adenocarcinoma del recto, que se sometieron a cirugía radical y disección de nódulos linfáticos laterales en 15 hospitales participantes, se inscribieron en el estudio y se asignaron a cohortes de entrenamiento (n = 139), prueba (n = 17) o validación (n = 53).PRINCIPALES MEDIDAS DE RESULTADO:En el grupo de tratamiento neoadyuvante, las imágenes tomadas antes del tratamiento se clasificaron como imágenes de referencia y las posteriores al tratamiento, como imágenes previas a la cirugía. En el grupo de cirugía inicial, las imágenes previas a la cirugía se clasificaron como imágenes de referencia y previas a la cirugía. Construimos dos tipos de inteligencia artificial, utilizando imágenes de referencia y previas a la cirugía, ingresando los parches de estas imágenes en ResNet-18. Evaluamos la precisión diagnóstica de los dos tipos de inteligencia artificial.RESULTADOS:En general, 124 pacientes se sometieron a cirugía solamente, 52 recibieron quimioterapia neoadyuvante y 33 recibieron quimiorradioterapia. El número de nódulos linfáticos laterales removidos en los cohortes de entrenamiento, prueba y validación fue de 2,418; 279 y 850, respectivamente. Las tasas metastásicas fueron 2.8%, 0.7%, y 3.7%, respectivamente. En el cohorte de validación, el área de recuperación de precisión bajo la curva fue de 0.870 y 0.963 para las imágenes de referencia y antes de la cirugía, respectivamente. Aunque tanto las imágenes previas a la cirugía como las iniciales proporcionaron una buena precisión para diagnosticar metástasis en los nódulos linfáticos laterales, la precisión de las imágenes previas a la cirugía fue mejor que la de las imágenes iniciales.LIMITACIONES:El número de casos es pequeño.CONCLUSIÓN:La inteligencia artificial es una herramienta prometedora para diagnosticar metástasis en los nódulos linfáticos laterales con alta precisión.

Osteoporotic vertebral fractures are recognized as a serious problem in the aging society. In this study, we found that the cumulated ambulation score predicts returning home in patients with osteoporotic vertebral fractures. The cumulated ambulation score is an important piece of information in determining the destination of patients with osteoporotic vertebral fractures. PURPOSE: Osteoporotic vertebral fractures are a serious problem affecting the health status of the elderly, and if they require inpatient treatment, they may have difficulty deciding where to discharge. The study's purpose is to investigate whether the cumulated ambulation scores predict returning home for hospitalized osteoporotic vertebral fractures patients. METHODS: The subjects were 120 osteoporotic vertebral fractures patients aged 65 years or older who were admitted to our hospital between April 2015 and March 2022. The cumulated ambulation scores for all subjects were measured in the 3-days right after admission. A multivariable analysis was performed with the dependent variable as whether the patient returned home and the independent variable as the cumulated ambulation score. Three models were created from the measured cumulated ambulation score, and each model was analyzed as an independent variable (model 1; score on the 1st day, model 2; total score on the 2-days, model 3; total score on the 3-days). RESULTS: The length of hospitalization for the osteoporotic vertebral fracture's patients were 11.8 ± 5.3 days, and 80 (66.7%) returned home. Multivariable analysis showed that cumulated ambulation score was a predictor of returning home (model 1, odds ratio: 3.151, 95% confidence interval: 2.074-5.203; model 2, odds ratio: 2.234, 95% confidence interval: 1.685-3.187; model 3, odds ratio: 1.929, 95% confidence interval: 1.535-2.599). CONCLUSION: The cumulated ambulation score of patients with osteoporotic vertebral fractures right after admission is a factor that affected returning home and is useful in determining where patients are discharged.

PURPOSE: The aim is to investigate whether a simple prone posture assessment test (P-test) at baseline can be predict the effectiveness of at least 3 months of physiotherapy for adults with structural spinal disorders. METHODS: Seventy-six adults (age 71.0 ± 7.1 years) with structural spinal disorders who visited our outpatient clinic and underwent physiotherapy, which included muscle strength and range of motion training was provided once a week for a minimum of 3 months, and where the load was adjusted individually by the physiotherapist. The P-test is performed with the subject lying on the bed in a prone position and is positive if no low back pain is seen and the abdomen touches the bed. The Oswestry Disability Index (ODI) was used to assess disability. The minimum clinically important difference (MCID) was set at 10% improvement of the ODI score. Logistic regression analysis was performed to investigate the association between baseline P-test and achievement of ODI-MCID. RESULTS: The study population characteristics were: Sagittal vertical axis 138.1 ± 73.2 mm; Pelvic tilt, 36.9 ± 9.8 degrees; Pelvic incidence minus lumbar lordosis, 45.3 ± 22.1 degrees; and maximum coronal Cobb angle, 21.3 ± 19.7 degrees. Logistic regression analysis showed that being positive on the P-test was associated with the achievement of ODI-MCID (Odds ratio, 8.381; 95% confidence interval, 2.487-35.257). CONCLUSIONS: This study found that our developed P-test was a useful predictor of achieving the ODI-MCID in a cohort of adults with structural spinal disorders receiving at least 3 months of physiotherapy.

BACKGROUND: Surgical and oncological outcomes of lower rectal cancer remain unsatisfactory. We investigated the short term and long term outcomes of robotic surgery for sphincter function-preserving surgery(SPS)for lower rectal cancer. METHOD: 433 lower rectal cancer patients who underwent SPS at our institution from January 2000 to July 2021 were included, excluding Stage â £ cases and patients with multiple cancers. There were 288 cases of laparotomy, 81 cases of laparoscopic surgery, and 64 cases of robotic surgery; we abbreviated the group names as: OP, LAP, and R, respectively. We retrospectively reviewed the anastomotic leakage rate and prognosis of these groups. RESULTS: The anastomotic leakage rate was 23.6% in the OP group, 17.3% in the LAP group, and 6.3% in the R group, with a significant difference between the OP group and the R group. The 3-year recurrence free survival rate was 86.7% in the LAP group and 95.6% in the R group. Although there was no significant difference, the prognosis tended to be better in the R group. Local recurrence was observed in 3 patients in the LAP group and 1 patient in the R group. CONCLUSION: In SPS for advanced lower rectal cancer, robotic surgery may contribute to a reduction in anastomotic leakage.

In patients undergoing mastectomy for locally advanced breast cancer, surgical skin flap reconstruction is sometimes required in order to cover large skin defects. Generally, we reconstruct by using latissimus dorsi or rectus abdominis when the direct closure is difficult. These constructions are difficult and have various complications. Our facility started rhomboid flap reconstruction after mastectomy. We report the result of rhomboid flap reconstruction. Five patients were performed rhomboid flap reconstruction. Three of 5 patients were cutaneous invasion, 1 patient was skin metastasis after mastectomy, and the other patient was Paget's disease. Regarding post operative complications, there were 2 cases of surgical site infection, 2 cases of skin necrosis and 1 case of seroma. The median length of postoperative hospital stay was 9 days. Median follow-up period was 381 days(221-508 days). Only 1 patient progressed. The median progression-free survival was 332 days(221-508 days). Rhomboid flap reconstruction is effective way for the improvement of the QOL of the patients with advanced breast cancer because the long term result was not bad and we can repair large skin defect easily.

PURPOSE: The purpose of this study was to evaluate the gait posture of patients with adult spinal deformity (ASD) using a 3-dimensional motion analysis system (3DMAS) and to investigate whether it affects gait endurance. METHODS: Fifty-one patients with ASD aged 50 years or older who were admitted to our hospital between March 2016 and March 2018 were included in the study. The subjects completed the 6-min walking test, which is an indicator of gait endurance. Static standing posture was assessed by whole-spine x-ray examination (coronal cobb angle, CCA; sagittal vertical axis, SVA; pelvic tilt, PT; and pelvic incidence minus lumbar lordosis, PI-LL). In addition, the gait posture was evaluated by a 3DMAS (dynamic trunk tilt angle, DTA; and dynamic pelvic tilt angle, DPA). The relationship between standing and gait postures and gait endurance was investigated by multivariable analysis. RESULTS: In univariable analysis, SVA, PI-LL, and DTA were associated with gait endurance. Furthermore, in the multivariable analysis, DTA showed the strongest association among the static and dynamic parameters (R2 = 0.61, ß = - 0.35, P < 0.05). CONCLUSIONS: An association was found between gait posture and gait endurance in patients with ASD. These findings can be useful to health care providers treating patients with ASD. It is advisable to assess the gait posture of patients with ASD because they present postural abnormalities during gait.

BACKGROUND: LLND in cases with suspected lateral lymph node (LLN) metastasis has been focused on as a novel treatment strategy in recent years. However, the optimal indication for LLND in rectal cancer patients has not been determined. This study aimed to establish the optimal indication for lateral lymph node dissection (LLND) in patients with rectal cancer using magnetic resonance imaging (MRI). METHODS: A total of 209 patients with rectal adenocarcinoma who underwent total mesorectal excision and LLND in 13 hospitals were prospectively registered. By matching the sizes of the harvested LNs and those in magnetic resonance imaging (MRI), the pathological outcome of each LN was confirmed one-by-one. Using parameters of the LLNs in MRI, the optimal diagnostic criteria for LLND were established. RESULTS: Of 3241 harvested LLNs, including 83 metastatic nodes, 1010 (31.1%) were visualized on MRI. Although all parameters assessed showed strong correlations with the presence of metastasis, none of these parameters could discriminate metastatic LLNs from non-metastatic nodes with sufficient sensitivity. However, by using the combination of long axis and short/long ratio in pretreatment MRI, we could establish optimal criteria for LLND. The sensitivity and specificity of the criteria for LLN metastasis were 94.3% and 40.2%, respectively. CONCLUSIONS: In conclusion, we established novel criteria for LLND in rectal cancer patients using MRI. Our criteria will be of great clinical use in determining indications for LLND.

The patient is a 63-year-old man. He visited his previous physician for abdominal pain. After close examinations, he was diagnosed with stenotic sigmoid colon cancer with left lateral lymph node metastasis. On the same day, colonic stenting was performed to relieve the symptoms of stenosis. After 1 month of stenting, a robot-assisted laparoscopic sigmoid colectomy and left lateral lymph node dissection were performed. Postoperative pathological examination revealed regional lymph node metastasis and left lateral lymph node metastasis(#283); the patient was diagnosed with pT4aN1bM1a(LYM), fStage â £a. The patient was discharged on postoperative day 10, and is stable 5 months after surgery without recurrence. This case suggests that robot-assisted laparoscopic lateral lymph node dissection can be effective even in atypical cases of sigmoid colon cancer with lateral lymph node metastasis.
