Objective: Parametrial tissue ligation during total laparoscopic hysterectomy (TLH) is important in large uteri with large vessels. Methods: A retrospective study was performed at Asan Medical Center for comparing TLH performed with a new knotless parametrial tissue ligation method and conventional laparoscopic-assisted vaginal hysterectomy (LAVH) from March 2019 to August 2021. For TLH, after anterior colpotomy, the parametrial tissue was ligated by anchoring the suture and making a loop in one direction three times using 1-0 V-LocTM 180 (Covidien, Mansfield, MA, USA) suture. Subsequently, the cranial part of the loop was cut using an endoscopic device. Results: A total of 119 and 178 patients were included in the TLH and LAVH groups, respectively. The maximal diameter of the uterus was larger in the TLH group (106.29±27.16 cm) than in the LAVH group (99.00±18.92 cm, P=0.01). The change in hemoglobin (Hb) level was greater in the LAVH group than in the TLH group (P<0.001). The weight of the removed uterus was greater in the TLH group than in the LAVH group (431.95±394.97 vs. 354.94±209.52 g; P=0.03). However, when the uterine weight was >1,000 g, the operative times and change in Hb levels were similar between the two groups. In both groups, no ureteral complications occurred during or after surgery. Conclusion Knotless parametrial tissue ligation using 1-0 V-LocTM 180 suture in TLH can be safely applied, even in cases with large uteri, without increased risks of ureteral injury or uterine bleeding.

Objectives: : The purpose of this study is to analyze Mental health literacy in General population. Methods: : We analyze the National Mental Health Literacy and Attitude Survey Data in 2021. We investigate 2016 general population and evaluate sociodemographic characteristics, Mental health literacy and stigma. We utilize 4 Case vignette which consist of Major Depressive Disorder, Schizophrenia, Alcohol Use Disorder and Suicidal Ideation. Results: : Schizophrenia (27.6%) have the lower disease recognition compare to Major Depressive Disorder (43.8%) and Alcohol Use Disorder (61.7%) (p<0.001). The stigma of Alcohol use disorder (52.8%) is highest and the stigma of Schizophrenia (47.2%) is the second highest (p<0.001). Conclusions : The education and overcoming the stigma in Mental health is needed in Schizophrenia and Alcohol Use Disorder.

Purpose: Here, we compared the operative and perioperative outcomes between robot-assisted laparoscopic myomectomy (RALM) and abdominal myomectomy (AM) in patients with large (>10 cm) or heavy myomas (>250 g). Materials and Methods: We included 278 patients who underwent multi-port RALM (n=126) or AM (n=151) for large or heavy myomas in a tertiary care hospital between April 2019 and June 2020. The t-test, chi-square, Bonferroni’s test, and multiple linear regression were used. Results: No differences were observed in age, body mass index, parity, or history of pelvic surgery between the two groups. Myoma diameters were not different (10.8±2.52 cm vs. 11.2±3.0 cm, p=0.233), but myomas were lighter in the RALM group than in the AM group (444.6±283.14 g vs. 604.68±368.35 g, respectively, p=0.001). The RALM group had a higher proportion of subserosal myomas, fewer myomas, fewer large myomas over >3 cm, lighter myomas, and longer total operating time. However, the RALM group also had shorter hospital stay and fewer short-term complications. Estimated blood loss (EBL) was not different between the two groups. The number of removed myomas was the most significant factor (coefficient=10.89, p<0.0001) affecting the EBL. Conclusion RALM is a feasible myomectomy technique even for large or heavy myomas. RALM patients tend to have shorter hospital stays and fewer postoperative fevers within 48 hours. However, RALM has longer total operating time.

PURPOSE: To compare the outcome between laparoscopic gastrojejunostomy (LapGJ) and duodenal stenting (DS) in terms of oral intake, nutritional status, patency duration, effect on chemotherapy and survival. METHODS: Medical records of 115 patients, who had LapGJ or duodenal stent placement between July 2005 and September 2015 in Seoul National University Bundang Hospital, have been reviewed retrospectively. Oral intake was measured with Gastric Outlet Obstruction Scoring System. Serum albumin and body weight was measured as indicators of nutritional status. The duration of patency was measured until the date of reintervention. Chemotherapy effect was calculated after the procedures. Survival period and oral intake was analyzed by propensity score matching age, sex, T-stage, comorbidities, and chemotherapy status. RESULTS: Forty-three LapGJ patients and 58 DS patients were enrolled. Improvement in oral intake was shown in LapGJ group versus DS group (88% vs. 59%, P = 0.011). Serum albumin showed slight but significant increase after LapGJ (+0.75 mg/dL vs. −0.15 mg/dL, P = 0.002); however, there was no difference in their body weight (+5.1 kg vs. −1.0 kg, P = 0.670). Patients tolerated chemotherapy longer without dosage reduction after LapGJ (243 days vs. 74 days, P = 0.006) and maintained the entire chemotherapy regimen after the procedure longer in LapGJ group (247 days vs. 137 days, P = 0.042). LapGJ showed significantly longer survival than DS (220 vs. 114 days, P = 0.004). CONCLUSION: DS can provide faster symptom relief but LapGJ can provide improved oral intake, better compliance to chemotherapy, and longer survival. Therefore, LapGJ should be the first choice in gastric outlet obstruction patients for long-term and better quality of life.

BACKGROUND/AIMS: This study aims to identify the gene mutation pattern associated with antibiotic resistance for mainly used antibiotics in Helicobacter pylori strains isolated from Koreans. MATERIALS AND METHODS: Seventy-one H. pylori strains were isolated from gastric mucosal biopsy specimens. The specimens were cultivated and the resistance to 5 antibiotics were assessed by using agar gel dilution method. DNA sequencing was carried out to detect the resistance-related gene mutations. RESULTS: A point mutation at A2143G of 23S rRNA was observed in all of the clarithromycin resistant strains, but tetracycline resistant strains were not found. Substitution N562Y in penicillin binding protein 1 were observed in an amoxicillin resistant strain (minimum inhibitory concentration [MIC] 2.0microg/mL). Eleven (57.8%) out of 19 levofloxacin resistant strains showed amino acid substitution at N87K (8 strains), N87I, A88V and D91N in GyrA. The truncation in rdxA was detected in 8 (25.0%) out of 32 metronidazole resistant strains. Two out of the 7 patients who failed in first-line treatment of clarithromycin and amoxicillin showed A2143G mutation. CONCLUSIONS: 23S rRNA mutation is closely related to the failure of eradication, however, the fact that five people who have no gene mutation failed eradication implies that other factors are related. As MIC levels in clarithromycin and levofloxacin resistance strains are getting higher, their appropriate gene mutation is more correlated.

BACKGROUND: Clarithromycin, amoxicillin, metronidazole, tetracycline, and levofloxacin have been commonly used for the eradication of Helicobacter pylori. We compared the change in antibiotic resistance of H. pylori strains during two separate periods and investigated the effect of antibiotic resistance on H. pylori eradication. METHODS: H. pylori strains were isolated from 71 patients between 2009 and 2010 and from 94 patients between 2011 and 2012. The distribution of minimal inhibitory concentration (MIC) of 5 antibiotics was assessed using the agar dilution method, and H. pylori eradication based on the antimicrobial susceptibility of the isolates was investigated retrospectively. RESULTS: Antibiotic resistance rate against clarithromycin, amoxicillin, tetracycline, metronidazole, and levofloxacin for the 2009-2010 isolates were 7.0% (5/71), 2.8% (2/71), 0% (0/71), 45.1% (32/71), and 26.8% (19/71), respectively, and for the 2011-2012 isolates were 16.0% (15/94), 2.1% (2/94), 0% (0/94), 56.3% (53/94), and 22.3% (21/94), respectively. Multi-drug resistance for 2 or more antibiotics increased slightly from 16.9% (12/71) in the 2009-2010 isolates to 23.4% (22/94) in the 2011-2012 isolates. In follow-up testing of 66 patients, first-line treatment successfully eradicated H. pylori in 50 patients (75.8%) and failed in 4 of 7 patients (57.1%) in a clarithromycin-resistant and amoxicillin-susceptible group. CONCLUSIONS: We observed an increase in resistance to clarithromycin and an overall increase in multi-drug resistance during the 2 study periods. The effectiveness of the eradication regimen was low with combinations of clarithromycin and amoxicillin, particularly in the clarithromycin-resistant group. Thus, eradication of H. pylori depends upon periodic monitoring of antimicrobial susceptibility.

Pigtail catheter drainage is a common procedure for the treatment of pleural effusion and pneumothorax. The most common complications of pigtail catheter insertion are pneumothorax, hemorrhage and chest pains. Cerebral air embolism is rare, but often fatal. In this paper, we report a case of cerebral air embolism in association with the insertion of a pigtail catheter for the drainage of a pleural effusion. A 67-year-old man is being presented with dyspnea, cough and right-side chest pains and was administered antibiotics for the treatment of pneumonia. The pneumonia failed to resolve and a loculated parapneumonic pleural effusion developed. A pigtail catheter was inserted in order to drain the pleural effusion, which resulted in cerebral air embolism. The patient was administered high-flow oxygen therapy and recovered without any neurologic complications.

BACKGROUND: In uncontrolled hemoptysis patient, bronchial arteriography and bronchial artery embolization (BAE) is a important procedure in diagnosis and treatment. The aim of this study is to assess the incidence of contrast-induced nephropathy and the risk factors of contrast-induced nephropathy (CIN) after bronchial arteriography and BAE. METHODS: We retrospectively reviewed the medical records of the patients who underwent bronchial arteriography and BAE in two university hospitals from January 2003 to December 2011. CIN was defined as rise of serum creatinine more than 25% of baseline value or 0.5 mg/dL at between 48 hours and 96 hours after bronchial arteriography and BAE. We excluded patients who already had severe renal insufficiency (serum creatinine> or =4.0) or had been receiving dialysis. RESULTS: Of the total 100 screened patients, 88 patients met the enrollment criteria. CIN developed in 7 patients (8.0%). The mean duration between the exposure and development of CIN was 2.35+/-0.81 days. By using multivariate analysis, serum albumin level was found to be significantly associated with the development of CIN (p=0.0219). CONCLUSION: These findings suggest that the incidence of CIN was higher than expected and patients with hypoalbuminemia should be monitored more carefully to prevent the development of CIN after bronchial arteriography and BAE.

Reports of metastatic hepatocellular carcinoma (HCC) without a primary liver tumor are rare. Here we present a case of isolated HCC that had metastasized to the pelvic bone without a primary focus. A 73-year-old man presented with severe back and right-leg pain. Radiological examinations, including computed tomography (CT) and magnetic resonance imaging (MRI), revealed a huge mass on the pelvic bone (13x10 cm). He underwent an incisional biopsy, and the results of the subsequent histological examination were consistent with metastatic hepatocellular carcinoma. The tumor cells were positive for cytokeratin (AE1/AE3), hepatocyte paraffin 1, and glypican-3, and negative for CD56, chromogranin A, and synaptophysin on immunohistochemical staining. Examination of the liver by CT, MRI, positron-emission tomography scan, and angiography produced no evidence of a primary tumor. Radiotherapy and transarterial chemoembolization were performed on the pelvic bone, followed by systemic chemotherapy. These combination treatments resulted in tumor regression with necrotic changes. However, multiple lung metastases developed 1 year after the treatment, and the patient was treated with additional systemic chemotherapy.
