Background: A prospective cohort study was conducted on 103 patients who underwent arthroscopic knee surgery at the National Trauma and Orthopedic Research Center and Grandmed Hospital between 2020 and 2023. This study examined the short-term clinical outcomes of the surgery in terms of anxiety and satisfaction. Arthroscopic knee surgery is an effective treatment, providing short-term pain relief and improved function. Arthroscopic meniscal surgery is a minimally invasive procedure aimed at reducing pain, restoring functional activity, and preventing irreversible degenerative changes of the knee joint. In recent years, the incidence of meniscal injuries, associated knee pain, functional impairment, and progressive joint degeneration changes has steadily increased. Aim: This study aimed to evaluate short-term clinical outcomes of arthroscopic meniscal surgery for meniscal tears and to compare these outcomes in relation to anxiety and patient satisfaction. Materials and Methods: A prospective cohort study was conducted between 2020 and 2023, including 103 patients who underwent arthroscopic meniscal surgery at the National Trauma and Orthopedic Research Center and Grandmed Hospital. Among them, 69 patients underwent partial meniscectomy, and 34 patients underwent meniscal repair. Clinical outcomes were assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS) before and after surgery. Result: Significant improvements were observed in all KOOS subscale scores postoperatively compared with preoperative values. Mean scores for pain improved from 57.93±12.58 to 80.93±5.70, symptoms from 54.13±12.73 to 80.27±6.22, activities of daily living from 61.28±13.19 to 79.61±4.91, sport and recreation from 42.28±13.21 to 72.04±6.88, and knee-related quality of life from 45.08±12.46 to 77.85±7.96, all demonstrating statistically significant improvement. Conclusion Arthroscopic meniscal surgery demonstrates favorable short-term clinical outcomes, effectively reducing pain and improving knee function and quality of life. These findings support the effectiveness of arthroscopic intervention and highlight the importance of considering psychological factors such as anxiety and patient satisfaction in postoperative evaluation.

In Europe, colorectal cancer (CRC) is the second most frequent malignancy and the second commonest cause of death from cancer. -The prognosis of CRC patients is dependent on the stage of disease at the time of diagnosis. Contrast-enhanced computed tomography (CT) examinations allows simultaneous assessment of tumor’s local staging, estimation of its possible invasion into neighboring organs, and detection of nodal and distant metastases; which is essential for appropriate treatment planning and estimation of its outcomes. The lack of reports on CT findings in CRC in Mongolia, increase in CRCmorbidity, and significant potential benefits of early detection served as background for this study.We investigated subjects with histologically proven adenocarcinoma who underwent CRC-related operative treatment either at National Cancer Center, First State Central Hospital, or Ulaanbaatar Songdo Hospital (UBSH) in 2009-2012. We retrospectively reviewed and analyzed from the UBSH’ database their preoperative CT, colonoscopy, surgical and pathohistologic reports using PACSPLUS,OCS operation systems. CECT examinations were performed at Siemens Somatom 64 multidetector scanner.Countrywide, 111 patients underwent surgery for colorectal cancer in 2009-2012. Totally, we involved86 subjects, whose age ranged from 25 to 87 years (mean 61.3years ±13.7SD). The F: M= 48 (55.8%) :38 (44.2%).The CECT determined T2 staging in 10/86 (11.6%),T3 in 61/86 (70.9%); T4 in 15/86 (17.4%);a significant difference in T-staging between CECT and histopathological examination (х2=41.28, p=0.00 (p<0.05)) was found. The CECT detected no peritumoral lymphadenopathy (N0) in 39/86 (45.3%), N1 in 18/86 (20.9%) and N2 in 29/86 (33.7%) patients; there was a significant difference in N-staging between CT and histopathological evaluation (х2=17.74, p=0.007(p<0.05)). For T-staging, CECT evaluation yielded sensitivity of 50% in T2 , 83.6% in T3, 71.4% in T4 staging; Diagnostic accuracy of CT for T2 staging was 89.7%, for T3- 78.2%, for T4- 88.7%. For N-staging, CECT had sensitivity of 88.2%, specificity of 64% and accuracy of 73.8%.Preoperative colorectal cancer patients in Mongolia receive initial MDCT in late stage. The similarsensitivity in staging of T-parameter to that of the international comparable studies. Nodal heterogeneity on CECT was more sensitive for nodal metastases than the size.

Purpose: To evaluate colorectal cancer localization in preoperative patients in Mongolia using CECTand endoscopyMaterials and Methods: Totally 10575 optic colonoscopy examinations were performed at UlaanbaatarSongdo Hospital between January 2009 and December 2012. From these examinations, colorectal cancerwas detected in 218 cases; from them 175 had CT examinations. From patients with CT examinations,111 underwent surgery at UBSH, National Cancer Center, State Central Hospital. (64MDCT SiemensSomatom). Only 86 patients with colorectal carcinoma proved by endoscopic or operative pathologywere included into this study. We retrospectively reviewed from the UBSH’ database their preoperativeCT, colonoscopy, surgical and pathohistologic reports using PACSPLUS, OCS operation systems. Toclassify colorectal tumor localization, we divided colon into 8 anatomic parts. The size of tumor wasmeasured as longest dimension visible on CT examination.Results: Study population’s age range was 25-87 age (mean 61.3years ±13.7SD). F: M= 48 (55.8%):38 (44.2%). Urban residents composed 58 (67.4%), rural- 27 (31.4%), foreigner- 1 (1.2%). Tumor sizerange on CT was 0-13 ñì (mean 6.5±2.2 ñì) . Colonoscopy and CT detected colorectal cancer in rectumin 30(34.9%) and 31 (36.1%), in sigmoid colon in 21(24.4%)’’’ and 19(22.1%), in hepatic flexure- 9(10.5%) and 9(10.5%), retrospectively. Double (synchronous) colorectal cancer was detected in 1(1.1%)at colonoscopy and in 2 (2.2%) at CT.Conclusions: The 60-69 age group composed the largest group (38.4%) in colorectal cancer patients,with slight predominance of urban residents over rural and higher female predilection. Sigmoid andrectum are shown to have highest incidence in colorectal cancer. To our best knowledge, it is firstpublication on detection of synchronous colorectal cancer in Mongoliaby both CT and colonoscopy.CT examination is less risky and reliable method to evaluate the entire colonic length in patients withcolorectal cancer suspicion, if observers are skilled in detection of CT signs of colorectal cancer.

Goal: The purpose of this study is to identify issues of current situation of the health information system in the health care facilities of Mongolia.Materials and Methods: A total 362 users as hospital directors, physicians, nurses, statisticians and IT workers of 105 health care facilities at primary, secondary and tertiary level participated in this study. Data collection methods were generated using a combination of questionnaires and in-depth interview of the users. The statistical analysis was carried out using the SPSS. Outcome measures were calculated with 95% confidence intervals (CI).Results: The survey results were shown that a vertical health information flow regulates in the health sector, internal networks set up and H-info 2.0 software as routine data processing and insurance claims are used in the hospitals of Mongolia. Regarding of e-health software as Computerized Physician Order Entry (CPOE), Drug Information System (DIS), Laboratory Information System (LIS) and Radiology Information System (RIS), 82.6% of the health care facilities used only CPOE. There 50% of the existed e-health software is not integrated in the health care facilities. In the data management, 27.0% of the health care facilities that used e-health applications had no backup solution. 45.5% of total users said that the information technology human resource is insufficient. 70.0% of users responded as there did not any continues training program in health information technology. The study was determined lack of functions and difficulty of using the existed software and inadequate software operation and not user-friendliness are the causes of the most of dissatisfactions. Conclusions: A vertical health information flow, internal networks, routine statistic processing set up and mainly CPOE used in the health care facilities. However there is no integration of e-health software and lack of its capacity. It is required modern integrated health information system in the health sector of Mongolia.
