[Decreased appetite is associated with a decreased cognitive function in elderly patients with diabetes].

OBJECTIVE: To examine the relationship between decreased appetite and the cognitive function in elderly diabetic patients. METHODS: The study subjects were outpatients with diabetes who were 60 years of age or older, and who were managed at Ise Red Cross Hospital. The cognitive function was assessed using a self-administered Dementia Checklist. The Japanese version of the Simplified Nutritional Appetite Questionnaire (SNAQ) was used to measure decreased appetite. A logistic regression analysis, in which the dependent variable was cognitive decline and the explanatory variables were appetite loss and adjustment variables, was used to calculate the odds ratio for cognitive decline according to the presence of appetite loss. RESULTS: Four hundred eighty patients were included in the analysis. Seventeen percent of the patients had decreased appetite and 21% had a decreased cognitive function. The unadjusted and adjusted odds ratios of cognitive decline for those with decreased appetite were 2.78 (95% confidence interval (CI), 1.66-4.65; P<0.001) and 2.26 (95% CI, 1.16-4.37; P=0.015), respectively, based on the absence of decreased appetite. CONCLUSION: Decreased appetite in elderly patients with diabetes was associated with a decreased cognitive function.

[Vegetable-first eating habits are associated with a reduced risk of mild cognitive impairment in elderly diabetic patients].

OBJECTIVE: To examine the relationship between vegetable-first eating habits and the cognitive function in elderly patients with diabetes. METHODS: The subjects were outpatients with diabetes ≥60 years old at Ise Red Cross Hospital. A self-administered dementia checklist was used to assess mild cognitive impairment and dementia. The participants were asked to fill out a questionnaire on their vegetable-first eating habits and were classified into 4 groups: 0, 1, 2, and 3 times a day. The dependent variables were mild cognitive impairment and dementia, and the explanatory variable was vegetable-first eating habits (0 as a reference). RESULTS: In total, 358 patients were included in the analysis. The number of vegetable-first meals was 0 in 153 (42.7%), 1 in 48 (13.4%), 2 in 46 (12.8%), and 3 in 111 (31.1%) patients. The adjusted odds ratios for 1, 2, and 3 times of mild cognitive impairment were 0.83 (95% confidence interval [CI], 0.35-1.94; P=0.680), 0.81 (95% CI, 0.32-2.00; P=0.653), and 0.37 (95% CI, 0.17-0.81; P=0.014), respectively. However, there was no significant association between vegetable-first eating habits and dementia. CONCLUSION: In elderly patients with diabetes, a vegetable-first eating habit at each meal was associated with a decreased risk of mild cognitive impairment.

[Relationship between the type and number of social participation events and the cognitive function in older diabetics].

OBJECTIVE: To examine the relationship between the type and number of social participation events and the cognitive function in elderly patients with diabetes. METHODS: The subjects were diabetic outpatients of ≥60 years of age who were managed at Ise Red Cross Hospital. Mild cognitive impairment (MCI) and dementia were assessed using a self-administered dementia checklist. Six types of social participation activities and the number of participants were investigated. A logistic regression analysis with MCI and dementia as dependent variables, social participation as an explanatory variable, and adjustment variables was used to calculate the odds ratios for social participation according to the presence of MCI and dementia. RESULTS: In total, 352 patients were included in the analysis. Volunteer activities (P=0.012), hobbies (P=0.006), activities to share skills and experiences (P=0.026), and work (P=0.003) were significantly associated with dementia. Regarding the association between the amount of social participation and dementia, there was a decrease in the risk of dementia when the number of social participation was 2. However, social participation was not significantly associated with MCI in this study. CONCLUSION: The type and number of social participation events were found to be associated with the risk of dementia in elderly patients with diabetes.

[Difficulty experienced by family in supporting elderly diabetic patients is associated with a decline in patients' higher-level functions].

OBJECTIVE: To examine the relationship between difficulties experienced by family in supporting elderly patients with diabetes and these patients' higher-level functions. METHODS: The subjects were outpatients with diabetes ≥65 years old at Ise Red Cross Hospital and their family members. The Tokyo Metropolitan Institute of Gerontology Index of Competence (TMIG-IC) was used to assess patients' higher-level functions. The Japanese version of the Diabetes Caregiver Activity and Support Scale (D-CASS-J) was used to measure difficulties experienced by family in supporting elderly patients with diabetes. Using a multiple regression analysis with TMIG-IC scores (instrumental ADL, intellectual activity, and social participation) as the dependent variable and D-CASS-J scores (based on the highest scoring Q1 group among the three quartiles of D-CASS-J scores) as the explanatory variables, standardized regression coefficients (ß) for higher-level functions on the family's perceived support difficulties were calculated. RESULTS: In total, 429 patients (254 male patients and 175 female patients) were included in the analysis. For male patients, the adjusted beta values for TMIG-IC scores in Q2 and Q3 were -0.039 (P=0.649) and -0.352 (P<0.001), respectively, and the adjusted beta values for the instrumental ADL scores were -0.064 (P=0.455), -0.192 (P=0.047), -0.090 (P=0.375), and -0.360 (P=0.002) for the Intellectually Active scores, respectively, and the adjusted beta for social role scores were 0.054 (P=0.581) and -0.261 (P=0.019), respectively. However, there was no association between the patients' higher-level functions and family support difficulties among female patients. CONCLUSIONS: Difficulty experienced by the family in supporting elderly male patients with diabetes is associated with reduced higher-level functioning.

Diagnostic Performance of Near-Infrared Fluorescent Marking Clips in Laparoscopic Gastrectomy.

INTRODUCTION: Accurate tumor localization and resection margin acquisition are essential in gastric cancer surgery. Preoperative placement of marking clips in laparoscopic gastrectomy as well as intraoperative gastroscopy can be used for gastric cancer surgery. However, these procedures are not available at all institutions. We conducted a prospective clinical trial to investigate the diagnostic performance of near-infrared fluorescent clips (ZEOCLIP FS) in laparoscopic gastrectomy. MATERIALS AND METHODS: Patients with gastric cancer or neuroendocrine tumor in whom laparoscopic distal, pylorus-preserving, or proximal gastrectomy was planned were enrolled (n = 20) in this study. Fluorescent clips were placed proximal and/or distal to the tumor via gastroscopy on the day before surgery. During surgery, the clips were detected using a fluorescent laparoscope, and suturing was performed where fluorescence was detected. The clip locations were then confirmed via gastroscopy, and the stomach was transected. The primary endpoint was the detection rate of the marking clips using fluorescence, and the secondary endpoints were complications and distance between the clips and stitches. RESULTS: Among the 20 patients enrolled, distal and pylorus-preserving gastrectomies were performed in 18 and 2 patients, respectively. All clips were detected in 15 patients, indicating a detection rate of 75.0% (90% confidence interval: 54.4%-89.6%). Furthermore, no complications related to the clips were observed. The median distance between the clips and stitches was 5 (range, 0-10) mm. CONCLUSIONS: We report the feasibility and safety of preoperative placement and intraoperative detection of near-infrared fluorescent marking clips in laparoscopic gastrectomy.

[Decreased family caregiver satisfaction with diabetes treatment of elderly patients is associated with patient depressive symptoms].

OBJECTIVE: To examine the relationship between the dissatisfaction of family caregivers with diabetes treatment and depressive symptoms among the elderly. METHODS: The subjects were diabetic patients of 65 years of age or older and their family caregivers, who were outpatients at Ise Red Cross Hospital. The Japanese version of the Patient Health Questionnaire 9, which consists of nine items, was used to measure depressive symptoms. The Japanese version of the Treatment Satisfaction Scale for Caregivers of Dependent Diabetic Patients (STCD2-J) was used to measure the satisfaction of family caregivers with diabetes treatment. A logistic regression analysis was performed using depressive symptoms as dependent variable, satisfaction of the family caregiver with diabetes treatment as an explanatory variable, and adjustment variables. RESULTS: In total, 272 patients were included in the analysis. Taking the quintiles of STCD2-J scores, the adjusted odds ratios for patient depressive symptoms in Q2 (27-29), Q3 (24-26), Q4 (22-23) and Q5 (14-21) based on Q1 (30-36) (the group with the highest STCD2-J scores) were 2.44 (95% confidence interval (CI), 0.69-8.61; P=0.163), 3.08 (95% CI, 0.93-10.12; P=0.063), 2.69 (95% CI, 0.68-10.65; P=0.156), and 4.54 (95% CI, 1.44-14.32; P=0.010), respectively. CONCLUSION: We found that family caregivers' decreased satisfaction with diabetes treatment was associated with depressive symptoms. It is important to alert primary care physicians about depressive symptoms when they see family caregivers who show decreased satisfaction with diabetes treatment.

Poorly differentiated mucinous carcinoma of the ascending colon complicated by bilateral ovarian mature cystic teratomas in a 17-year-old female patient: a case report.

BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers worldwide, and screening colonoscopy has led to a decreasing incidence rate. However, the incidence of CRC is increasing among young people, especially adolescents and young adults (AYAs) who are not routinely screened. Although CRC is the fourth most common cancer among AYAs, it is extremely rare. In younger patients, CRC is often diagnosed later, and the proportion of patients with advanced CRC is higher than that in older patients. We herein present a case of poorly differentiated mucinous carcinoma of the ascending colon complicated by bilateral ovarian mature cystic teratomas (MCTs) in an AYA. CASE PRESENTATION: A 17-year-old female patient presented with a chief complaint of abdominal pain and diarrhea that had persisted for more than 3 years. Colonoscopy revealed circumferential wall thickening of the ascending colon, and colonic biopsy revealed a mucous mass and findings of adenocarcinoma, predominantly signet ring cell carcinoma. Abdominal computed tomography (CT) and pelvic magnetic resonance imaging (MRI) showed bilateral ovarian tumors. Laparoscopic right hemicolectomy and enucleation of bilateral ovarian tumors were performed. Although the ascending colon cancer formed a large mass, there were no signs of peritoneal dissemination or direct invasion to the surrounding organs. Microscopically, the ascending colon was a poorly differentiated mucinous carcinoma with signet ring cell carcinoma and lymph node metastasis (9/42). The ovarian tumors were diagnosed as MCTs without any malignant components. The pathological diagnosis was ascending colon cancer (pT4aN2bM0, pStage IIIC) and bilateral ovarian MCTs. Microsatellite instability (MSI) testing was negative, and there were no gene mutations in either RAS or BRAF. Postoperative adjuvant chemotherapy with oxaliplatin and 5-FU was started. CONCLUSIONS: We presented a case of locally advanced ascending colon cancer in a 17-year-old female patient. CRC rarely occurs in AYAs. However, the incidence has gradually increased in recent years. It should be considered as a differential diagnosis for young patients with long-term abdominal symptoms of unknown cause.

Equal short-term outcomes of intracorporeal mechanical gastrogastrostomy in laparoscopic pylorus-preserving gastrectomy for cT1N0 gastric cancer in the middle stomach compared with the extracorporeal hand-sewing method.

BACKGROUND: Intracorporeal mechanical gastrogastrostomy (IMG) techniques have recently been developed and their short-term safety was presented in their initial evaluation. However, whether they are comparable to extracorporeal hand-sewing gastrogastrostomy (EHG) remains unclear. The aim of the study is to establish the safety of IMG in totally laparoscopic pylorus-preserving gastrectomy (TLPPG) compared to EHG in laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG). METHODS: We retrospectively analyzed the short-term outcomes of patients with middle-third early gastric cancer who underwent LAPPG or TLPPG between 2005 and 2022. The primary objective of this study was to evaluate the non-inferiority of IMG to EHG in terms of safety, with the primary endpoint being the risk difference in anastomosis-related complications (ARCs). The sample size required to achieve a statistical power of 80% for the non-inferiority test was 971 with a one-sided alpha level of 5% and non-inferiority of 5%. RESULTS: The analysis included a total of 1,021 patients who underwent LAPPG or TLPPG during the study period. Among them, 488 patients underwent EHG, while 533 underwent IMG. The incidences of ARCs were 11.3% and 11.4% in EHG and IMG, respectively. The observed difference in incidence was 0.0017 (90% confidence interval - 0.0313 to 0.0345), which statistically demonstrated the non-inferiority of IMG to EHG in the incidence of ARCs. Among other complications, the incidence of wound infection in IMG was lower than that in EHG. CONCLUSION: IMG is safe regarding ARCs compared with EHG. These results will encourage surgeons to introduce IMG for patients with early middle gastric cancer.

Development of the "Social Participation Barriers in Patients With Diabetes" Questionnaire for Older Patients With Diabetes and Evaluation of its Reliability and Validity.

Objectives: To develop a questionnaire for evaluating the factors hindering social participation in older patients with diabetes (the Social Participation Barriers in Patients with Diabetes [SPBD] questionnaire) and assess its reliability and validity. Materials and Methods: This is a cross-sectional study. This study included outpatients aged ≥60 years having diabetes and undergoing treatment at the Ise Redcross Hospital. A draft questionnaire consisting of 20 questions was developed with reference to previous studies. Logistic regression analysis was conducted, and Cronbach's alpha coefficient was calculated. Exploratory factor analysis was conducted to test construct validity. Pearson's correlation coefficients between SPBD scores and frailty scores, social frailty scores and frequency of outings were calculated. Results: Overall, 353 patients were included in the analysis. After questions without an association in the logistic regression analysis were excluded and results of the exploratory factor analyses were obtained, 10 questions were excluded. As a result, we created a 10-item SPBD questionnaire. Cronbach's alpha coefficient was .87. The SPBD score was significantly associated with frequency of going out, and frailty. Conclusions: We created an SPBD questionnaire to assess barriers to social participation in older adult patients with diabetes. This study indicated the validity and reliability of the questionnaire.

Impact of Olfactory Change on Postoperative Body Weight Loss in Patients with Gastric Cancer after Gastrectomy.

Patients undergoing gastrectomy for gastric cancer may experience alterations in olfaction, yet the association between olfactory changes and postoperative weight loss remains uncertain. This study aimed to elucidate the relationship between olfactory changes and postoperative weight loss in patients with gastric cancer. Patients who underwent radical gastrectomy for gastric cancer between February 2022 and August 2022 were included in the study. Those experiencing a higher Visual Analog Scale (VAS) score postoperatively compared to preoperatively were deemed to have undergone olfactory changes. Postoperative weight loss was determined using the 75th percentile as a cutoff value, designating patients surpassing this threshold as experiencing significant weight loss. Multivariate logistic regression analysis was employed to identify risk factors for postoperative weight loss, with statistical significance set at p < 0.05. Out of 58 patients, 10 (17.2%) exhibited olfactory changes. The rate of postoperative weight loss at one month was markedly higher in the group with olfactory changes compared to those without (9.6% versus 6.2%, respectively; p = 0.002). In addition, the group experiencing olfactory changes demonstrated significantly lower energy intake compared to the group without such changes (1050 kcal versus 1250 kcal, respectively; p = 0.029). Logistic regression analysis revealed olfactory changes as an independent risk factor for significant weight loss at one month postoperatively (odds ratio: 7.64, 95% confidence interval: 1.09-71.85, p = 0.048). In conclusion, olfactory changes emerged as an independent risk factor for postoperative weight loss at one month in patients with gastric cancer following gastrectomy.

Impact of preoperative prealbumin levels on long-term prognosis in patients with gastric cancer after gastrectomy: a retrospective cohort study.

BACKGROUND: The relationship between preoperative prealbumin levels and long-term prognoses in patients with gastric cancer after gastrectomy has not been fully investigated. This study clarified the effect of preoperative prealbumin levels on the long-term prognosis of patients with gastric cancer after gastrectomy. METHODS: This retrospective cohort study included consecutive patients who underwent radical gastrectomy for primary pStage I-III gastric cancer and whose preoperative prealbumin levels were measured between May 2006 and March 2017. Participants were categorized according to their preoperative prealbumin levels into high (≥22 mg/dL), moderate (15-22 mg/dL), and low (<15 mg/dL) groups. The overall survival (OS) in the three groups was compared using the log-rank test, and prognostic factors were identified using Cox proportional hazards regression analysis. RESULTS: The median follow-up duration was 66 months. Of 4732 patients, 3649 (77.2%) were classified as high, 925 (19.6%) as moderate, and 158 (3.3%) as low. Lower prealbumin levels were associated with poorer prognoses (P < 0.001). Multivariate analysis showed that prealbumin levels of 15-22 mg/dL [hazard ratio (HR): 1.576, 95% confidence interval (CI): 1.353-1.835, P < 0.001] and <15 mg/dL (HR: 1.769, 95% CI: 1.376-2.276, P < 0.001) were independent poor prognostic factors for OS. When analyzed according to the cause of death, prealbumin levels were associated with other-cause survival, but not cancer-specific survival. CONCLUSIONS: Preoperative prealbumin levels correlated with OS in patients with gastric cancer after gastrectomy; the lower the prealbumin level, the worse is the prognosis. Prealbumin levels may be associated with other-cause survival.

Frequency and Overlap of Cachexia, Malnutrition, and Sarcopenia in Elderly Patients with Diabetes Mellitus: A Study Using AWGC, GLIM, and AWGS2019.

This study aimed to estimate the frequency and overlap of cachexia, malnutrition, and sarcopenia in elderly patients with diabetes mellitus. Patients who were aged at least 65 years, had diabetes mellitus, and were regularly visiting the Ise Red Cross Hospital on an outpatient basis were included. The patients were assessed to determine whether they had cachexia, malnutrition, and sarcopenia according to the Asian Working Group for Cachexia criteria, the Global Leadership Initiative on Malnutrition criteria, and the Asian Working Group for Sarcopenia 2019 criteria. A total of 510 patients (310 men and 200 women) were analyzed in this study. Sarcopenia, cachexia, and malnutrition were found in 84 patients (16.4%), 40 patients (7.8%) (17.8% among patients with chronic diseases), and 110 patients (21.5%), respectively. Among patients with sarcopenia, the frequencies of cachexia and malnutrition were 30% and 71.4%, respectively. Among patients with cachexia, the frequencies of sarcopenia and malnutrition were 65% and 90%, respectively, and among those with malnutrition, the frequencies of sarcopenia and cachexia were 54% and 32.7%, respectively. The overlap among cachexia, malnutrition, and sarcopenia appears to be an important factor to be considered in the treatment of elderly patients with diabetes mellitus.

Long-term impact of sarcopenia in older patients undergoing gastrectomy for gastric cancer: a systematic review and meta-analysis.

Background: Sarcopenia is an inevitable problem in older patients. After gastrectomy, patients often have an inadequate dietary intake and easily fall into sarcopenia. However, the impact of preoperative sarcopenia on long-term outcomes after gastrectomy has not been analyzed. Methods: A systematic review was conducted for all relevant articles identified on PubMed, the Cochrane Library, Web of Science, and ClinicalTrials.gov until April 2023. Adjusted hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the fixed or random effects model according to the heterogeneity. The Newcastle-Ottawa Scale was used to quantify study quality. Results: Seven studies involving 1,831 patients aged ≥65 years who underwent gastrectomy for gastric cancer were analyzed. Four hundred twelve patients (22.5%) were diagnosed with sarcopenia. The analysis showed that preoperative sarcopenia was significantly associated with poor overall survival (OS) (HR =1.93; 95% CI:1.60-2.34; P<0.001). Two of the included studies also showed that preoperative sarcopenia was significantly correlated with disease-related survival: one with disease-specific survival (DSS) (HR =4.00; 95% CI: 1.20-13.3, P=0.024) and the other with non-cancer specific survival (HR =3.27; 95% CI: 1.61-6.67; P=0.001). Furthermore, sarcopenic patients experienced more severe complications than non-sarcopenic patients (OR =1.80; 95% CI: 1.10-2.95; P=0.019). Conclusions: This meta-analysis suggested that preoperative sarcopenia is useful as a prognostic factor of impaired OS in older patients after gastrectomy. Preoperative evaluation and intervention for skeletal muscle loss should be considered. Further studies of sarcopenic impact on disease-related survival are required.

Effects of neoadjuvant therapy on health-related quality of life for patients with gastroesophageal cancer.

BACKGROUND: Neoadjuvant therapy in combination with surgery increases survival in gastroesophageal cancer; however, little is known about its impact on health-related quality of life. This study compared the impact of neoadjuvant therapy with that of surgery alone on the health-related quality of life in patients treated for gastroesophageal cancer. METHODS: A single-centre cohort study with prospectively collected data from patients undergoing curative intended treatment for gastroesophageal cancer between 2013 and 2020 was performed. Health-related quality of life was assessed prior to surgery and patients stratified according to neoadjuvant therapy or surgery alone. The primary endpoint was self-assessed health-related quality of life, evaluated using validated cancer-specific questionnaires. A pre-specified multivariable model adjusted for age, ASA score, and clinical T- and N-stage was used. RESULTS: A total of 361 patients were included, of whom 239 (61%) were treated with neoadjuvant therapy. Patients treated with neoadjuvant therapy reported less difficulties with eating restrictions (-11.9, p = 0.005), pain (-10.9, p = 0.004), and insomnia (-12.6, p = 0.004) than patients treated with surgery alone. Patients with oesophageal cancer and neoadjuvant therapy reported less dysphagia (-16.6, p < 0.001), eating restrictions (-23.2, p < 0.001), and odynophagia (-18.0, p = 0.002) than those who underwent surgery alone. CONCLUSION: Neoadjuvant therapy was associated with a significant reduction in symptoms affecting malnutrition and improved health-related quality of life in patients with gastroesophageal cancer. These results indicates that more patients might be available for neoadjuvant therapy, despite the baseline burden of gastroesophageal cancer.

[A low phase angle is a factor independently associated with falls in elderly diabetic patients].

OBJECTIVE: To examine the relationship between a low phase angle (PA) and falls in elderly diabetic patients. METHODS: The subjects were diabetic patients ≥65 years old who were outpatients at Ise Red Cross Hospital. Patients were asked about their fall history using a self-administered questionnaire. The PA was measured by the multi-frequency bioelectrical impedance method, and the subjects were classified into two groups: the first quartile with the smallest PA (T1 group) and the second and third quartiles (T2/3 groups). A logistic regression analysis with falls as the dependent variable, PA as the explanatory variable, and adjustment variables was used to calculate the odds ratio of the PA for falls. RESULTS: A total of 255 patients were included in the analysis of this study. Of these, 33.3% were in the T1 group, 66.7% were in the T2/3 group, and 28.2% had fallen. The unadjusted and adjusted odds ratios for falls in the PA were 2.92 (95% confidence interval [CI], 1.31-4.07; P=0.004) and 2.34 (95% CI, 1.07-5.09; P=0.031), respectively. CONCLUSION: A low PA was associated with falls in elderly diabetic patients.

[Loneliness is associated with the risk of low nutrition in elderly diabetic patients].

OBJECTIVE: The purpose of this study was to examine the relationship between loneliness and malnutrition in elderly diabetic patients. METHODS: The subjects were diabetic patients ≥65 years old who were outpatients at Ise Red Cross Hospital. The nutritional status was assessed using the Mini Nutritional Assessment Short Form (MNA-SF), and patients were defined as being undernourished if their total score was <11 points. Loneliness was assessed using the Japanese version of the short form of the loneliness scale, a self-administered questionnaire, and a total score of ≥6 was considered to indicate loneliness. A logistic regression analysis was used to calculate the adjusted odds ratio of loneliness to undernutrition, with the dependent variable being undernutrition, the explanatory variable being loneliness, and the adjustment variable being loneliness. RESULTS: A total of 163 patients were included in the analysis of this study. Of these, 25.8% were lonely, and 33.7% were undernourished. The unadjusted and adjusted odds ratios of loneliness to undernutrition were 2.55 (95% confidence interval [CI], 1.24-5.27; P=0.011) and 3.81 (95% CI, 1.27-11.39; P=0.017), respectively. CONCLUSION: Loneliness is associated with a low nutritional status in elderly diabetic patients. It is important to alert diabetic patients with loneliness to their low nutritional status when they are diagnosed.

Optimal resection of gastric bronchogenic cysts based on anatomical continuity with adherent gastric muscular layer: A case report.

BACKGROUND: Bronchogenic cysts are congenital lesions requiring radical resection because of malignant potential. However, a method for the optimal resection of these cysts has not been completely elucidated. CASE SUMMARY: Herein, we presented three patients with bronchogenic cysts that were located adjacent to the gastric wall and resected laparoscopically. The cysts were detected incidentally with no symptoms and the preoperative diagnosis was challenging to obtain via radiological examinations. Based on laparoscopic findings, the cyst was attached firmly to the gastric wall and the boundary between the gastric and cyst walls was difficult to identify. Consequently, resection of cysts alone caused cystic wall injury in Patient 1. Meanwhile, the cyst was resected completely along with a part of the gastric wall in Patient 2. Histopathological examination revealed the final diagnosis of bronchogenic cyst and revealed that the cyst wall shared the muscular layer with the gastric wall in Patients 1 and 2. In Patient 3, the cyst was located adjacent to the gastric wall but histopathologically originated from diaphragm rather than stomach. All the patients were free from recurrence. CONCLUSION: The findings of this study state that a safe and complete resection of bronchogenic cysts required the adherent gastric muscular layer or full-thickness dissection, if bronchogenic cysts are suspected via pre- and/or intraoperative findings.

Relationship between antithrombotic drugs and postoperative outcomes in patients with gastric cancer after gastrectomy: a propensity matching analysis.

BACKGROUND: As there is no consensus on the impact of antithrombotic drugs on post-gastrectomy outcomes in gastric cancer patients, this study aimed to investigate the impact of antithrombotic drugs on postoperative outcomes in these patients after gastrectomy. METHODS: Patients with Stage I-III primary gastric cancer who underwent radical gastrectomy between April 2005 and May 2022 were included. We performed propensity score matching to adjust for patient background and compared bleeding complications. Multivariate analysis with logistic regression analysis was performed to identify risk factors associated with bleeding complications. RESULTS: Of the 6798 patients, 310 (4.6%) were in the antithrombotic group and 6488 (95.4%) were in the non-antithrombotic group. Twenty-six patients (0.38%) experienced bleeding complications. After matching, the number of patients in each group was 300, with insignificant differences in any factor. A comparison of postoperative outcomes showed no difference in bleeding complications (P = 0.249). In the antithrombotic group, 39 (12.6%) continued drugs, and 271 (87.4%) discontinued them before surgery. After matching, there were 30 and 60 patients, respectively, with no differences in patient background. A comparison of postoperative outcomes showed no differences in bleeding complications (P = 0.551). In multivariate analysis, antithrombotic drug use and continuation of antiplatelet agents were not risk factors for bleeding complications. CONCLUSION: Antithrombotic drugs and its continuation may not worsen bleeding complications in patients with gastric cancer after radical gastrectomy. Bleeding complications were rare, and further studies are needed on risk factors for bleeding complications in larger databases.

Advantages of Function-Preserving Gastrectomy for Older Patients With Upper-Third Early Gastric Cancer: Maintenance of Nutritional Status and Favorable Survival.

PURPOSE: The incidence of early gastric cancer is increasing in older patients alongside life expectancy. For early gastric cancer of the upper third of the stomach, laparoscopic function-preserving gastrectomy (LFPG), including laparoscopic proximal gastrectomy (LPG) and laparoscopic subtotal gastrectomy (LSTG), is expected to be an alternative to laparoscopic total gastrectomy (LTG). However, whether LFPG has advantages over LTG in older patients remains unknown. MATERIALS AND METHODS: We retrospectively analyzed data of consecutive patients aged ≥75 years who underwent LTG, LPG, or LSTG for cT1N0M0 gastric cancer between 2005 and 2019. Surgical and nutritional outcomes, including blood parameters, percentage body weight (%BW) and percentage skeletal muscle index (%SMI) were compared between LTG and LPG or LSTG. Survival outcomes were also compared between LTG and LFPG groups. RESULTS: A total of 111 patients who underwent LTG (n=39), LPG (n=48), and LSTG (n=24) were enrolled in this study. To match the surgical indications, LTG was further categorized into "LTG for LPG" (LTG-P) and "LTG for LSTG" (LTG-S). No significant differences were identified in the incidence of postoperative complications among the procedures. Postoperative nutritional parameters, %BW and %SMI were better after LPG and LSTG than after LTG-P and LTG-S, respectively. The survival outcomes of LFPG were better than those of LTG. CONCLUSIONS: LFPG is safe for older patients and has advantages over LTG in terms of postoperative nutritional parameters, body weight, skeletal muscle-sparing, and survival. Therefore, LFPG for upper early gastric cancer should be considered in older patients.

["Koshi-heso" (waist-umbilicus) test: A novel screening method for visceral fatty obesity].

OBJECTIVE: To evaluate the screening performance and validity of the "Koshi-heso" (waist-umbilicus) test for visceral fatty obesity in elderly diabetic patients. METHODS: Subjects were diabetic patients ≥65 years old visiting our outpatient clinic. As a "Koshi-heso" test, the distance between the umbilicus and the superior border of the iliac crest (waist) was measured with the patient's own finger. When the index finger reached the umbilicus and there was a gap between the finger and the abdominal wall, the patient was classified as "smaller"; when the index finger reached the umbilicus and there was no gap between the finger and the abdominal wall, the patient was classified as "just fit"; and when the index finger did not reach the umbilicus, the patient was classified as "bigger". Abdominal circumference was used to assess visceral fat obesity, with a cut-off value of ≥85 cm for men and ≥90 cm for women. Visceral fat mass and body fat percentage were evaluated by the multi-frequency bioelectrical impedance method. The sensitivity and specificity of the waist-umbilical test for visceral fat obesity were calculated. Pearson's correlation coefficients between the "Koshi-heso" test and visceral fat mass and body fat percentage were calculated to evaluate the validity of the test. Furthermore, the association between the "Koshi-heso" test and risk factors for vascular disease, microvascular complications and cardiovascular disease was assessed by a logistic analysis. RESULTS: A total of 221 patients were included in the analysis population of the study. The cut-off values of "just fit" in men (sensitivity 0.96, specificity 0.62) and "bigger" in women (sensitivity 0.76, specificity 0.78) were optimal. Furthermore, the "Koshi-heso" test was significantly correlated with abdominal visceral fat mass and body fat percentage as well as with vascular disease risk factors and microvascular complications. CONCLUSION: The "Koshi-heso" test was able to be used as a screening method for visceral fatty obesity in elderly diabetic patients.
