Background/Aims:
Portal vein thrombosis (PVT) frequently occurs in patients with inflammatory bowel disease (IBD), particularly when influenced by factors such as abdominal infections, IBD flare-ups, or surgical procedures. The implications of PVT range from immediate issues such as intestinal ischemia to long-term concerns including portal hypertension and its complications. However, there is a notable gap in comprehensive studies on PVT in IBD, especially with the increasing incidence of IBD in Asia. This research aimed to evaluate the clinical features and outcomes of PVT in patients with IBD at a leading hospital in South Korea.
Methods:
This retrospective analysis reviewed adult patients diagnosed with both IBD and PVT from 1989 to 2021 at a renowned South Korean medical center. The study focused on patient characteristics, specifics of PVT, administered treatments, and outcomes, all confirmed through enhanced CT scans.
Results:
A total of 78 patients met the study’s criteria. Notably, only 20.5% (16/78) were treated with oral anticoagulants; however, a vast majority (96.2%; 75/78) achieved complete radiographic resolution (CRR). When comparing patients receiving anticoagulants to those who did not, a significant preference for anticoagulant use was observed in cases where the main portal vein was affected, as opposed to just the left or right veins (p = 0.006). However, multivariable analysis indicated that neither anticoagulant use nor previous surgeries significantly impacted CRR.
Conclusions
Patients with IBD and PVT generally had favorable outcomes, regardless of anticoagulant use.

The consequences of coronavirus disease 2019 (COVID-19) are particularly severe in older adults with a disproportionate number of severe and fatal outcomes. Therefore, this integrative review aimed to provide a comprehensive overview of the clinical characteristics, management approaches, and prognosis of older patients diagnosed with COVID-19. Common clinical presentations in older patients include fever, cough, and dyspnea. Additionally, preexisting comorbidities, especially diabetes and pulmonary and cardiovascular diseases, were frequently observed and associated with adverse outcomes. Management strategies varied, however, early diagnosis, vigilant monitoring, and multidisciplinary care were identified as key factors for enhancing patient outcomes. Nonetheless, the prognosis remains guarded for older patients, with increased rates of hospitalization, mechanical ventilation, and mortality. However, timely therapeutic interventions, especially antiviral and supportive treatments, have demonstrated some efficacy in mitigating the severe consequences in this age group. In conclusion, while older adults remain highly susceptible to severe outcomes from COVID-19, early intervention, rigorous monitoring, and comprehensive care can play a pivotal role in improving their clinical outcomes.

Clinical and Experimental Otorhinolaryngology 2022;15(4):354-363
Objectives:
. Post-radiation nasopharyngeal necrosis (PRNN) is a serious complication that severely impacts the quality of life and survival of nasopharyngeal carcinoma patients. Endoscopic debridement is considered the first-line treatment for PRNN. This study aimed to analyze clinical outcomes, focusing on the mucosal resurfacing status and the effectiveness of salvage operations.
Methods:
. Twenty-seven patients who underwent endoscopic debridement were retrospectively analyzed. The patients were divided into two groups according to the initial surgical modality: debridement with a nasoseptal flap (NSF; n=21) and debridement only (no NSF; n=6). Clinical features, postoperative mucosal status, internal carotid artery (ICA) rupture, survival, and final mucosal status were evaluated. The NSF group was categorized according to flap viability to analyze risk factors for flap failure.
Results:
. Regardless of the initial modality, most patients experienced symptom improvement (96.0% for headache and 100% for foul odor); however, complete cranial nerve palsy did not improve in any patients. In the NSF group, complete healing was observed in 66.7%, while all patients in the no-NSF group underwent salvage surgery because none maintained complete healing. In the NSF group, 19.0% of patients required salvage surgery. After the last operation, favorable symptom improvement was noted (100% for headache and 90.0% for foul odor), and 77.8% had completely healed mucosa, whereas only 14.8% and 7.4% had partial healing and persistent necrotic mucosal status. The necrotic or uncovered NSF subgroup showed statistically non-significant tendencies for old age, advanced necrosis stage, advanced T stage, ICA involvement, high frequency and dose of radiation therapy, diabetes mellitus, and underlying comorbidities. Two ICA ruptures and three deaths occurred.
Conclusion
. Resurfacing the nasopharynx with NSF after endoscopic debridement showed better outcomes than debridement only for PRNN treatment. Despite initial NSF failure, additional resurfacing reconstructive surgery offers advantages in symptom mitigation, quality of life, and survival.

Background/Aims:
The use of complementary and alternative medicine (CAM) is a global phenomenon, including inflammatory bowel disease (IBD) patients. We aimed to assess the change in prevalence and patterns of CAM use, and attitudes towards CAM over an 8-year time interval (2006 vs. 2014) among IBD patients in Korea.
Methods:
A total of 221 IBD patients (CD=142, UC=79) were asked to complete a questionnaire regarding CAM at two time points: at enrollment (2006) and 8 years later (2014/2015).
Results:
The proportion of patients ever using CAM increased significantly from 60.2% in 2006 to 79.6% in 2014 (P<0.001), while the proportion of current CAM users increased slightly (35.7% to 38.0%, P=0.635); 21.7% used CAM consistently at both time points. The proportion of patients who felt CAM was less effective (P<0.001) and more expensive (P=0.04) than conventional treatments increased over time. Also, the proportion among ever CAM users who perceived a positive effect from CAM significantly decreased in 2014 compared to 2006 (P=0.004). Higher education (adjusted odds ratio [aOR], 2.10), prior side effects to conventional therapies (aOR, 2.23), and prior use of corticosteroids (aOR, 2.51) were associated with CAM use. Interestingly, use of CAM before IBD diagnosis (aOR, 2.73) was significantly associated with consistent CAM use.
Conclusions
Although the attitudes toward CAM have become less favorable, the majority of IBD patients have experienced CAM with an overall increase of current CAM users over time. Moreover, more than half of current CAM users used CAM consistently over time.

Annals of Coloproctology 2020;36(5):344-348
Purpose:
This study was performed to evaluate the incidence of vasovagal reactions (VVRs) and the efficacy of lidocaine injection for prevention.
Methods:
One hundred seventeen patients diagnosed with hemorrhoids and scheduled to undergo a stapled hemorrhoidopexy (SH) were randomly divided according to submucosal injection to the rectum: lidocaine group (n = 53, lidocaine injected just before full closure of the stapler) and control group (n = 58). Outcomes included baseline patient characteristics (American Society of Anesthesiologists physical status classification, body mass index, diabetes mellitus, hypertension, and previous VVR history), vital signs during the operation, incidence of VVRs (hypotension, bradycardia, dizziness, diaphoresis, and nausea/vomiting), and postoperative complications (pain, bleeding, and urinary retention).
Results:
Baseline characteristics were similar between groups. The number of patients with lower abdominal pain after firing the stapler and incidence of dizziness were lower for the lidocaine group than for the control group (9.4% vs. 25.9%, P = 0.017; 0% vs. 8.6%, P = 0.035, respectively). However, there were no significant between-group differences in incidence of nausea and diaphoresis (0% vs. 3.4%, P = 0.172) and syncope (1.9% vs. 3.4%, P = 0.612). Fewer patients in the lidocaine group complained of postoperative pain (41.5% vs. 58.6%, P = 0.072), and these patients used analgesics less frequently than those in the control group (28.3% vs. 36.2%, P = 0.374).
Conclusion
Patients who received a submucosal lidocaine injection prior to SH experienced less lower abdominal pain and dizziness compared with those who received standard treatment. A larger, more detailed prospective study is needed for further analysis.

PURPOSE: The volume of thyroid cancer screening and subsequent thyroid fine-needle aspiration (FNA) have rapidly increased in South Korea. We analyzed the thyroid cancer diagnoses/thyroid FNA ratio according to the annual number of FNA to evaluate changes in the diagnosticefficiency of FNA. MATERIALS AND METHODS: This was a nationwide population-based retrospective cohort study. The overall thyroid cancer diagnoses/thyroid FNA ratio and annual incremental thyroid cancer diagnoses/incremental thyroid FNA ratio were indirectly calculated using data obtained from the Korea Central Cancer Registry database and the Korean National Health Insurance Service claims database from 2004 to 2012. Pearson correlation analyses were performed to evaluate the strength of linear associations between variables. RESULTS: The number of thyroid FNA increased from 28,596 to 177,805 (6.2-fold increase) from 2004 to 2012. The overall thyroid cancer diagnoses/thyroid FNA ratio decreased from 36.5% in 2004 to 25.1% in 2012 and was negatively correlated to the number of FNA (R=‒0.977, p < 0.001). The annual incremental thyroid cancer diagnoses/incremental thyroid FNA ratios (range, 15.3% to 30.7%) were always lower than the overall thyroid cancer diagnoses/thyroid FNA ratio in each year and also worsened according to the increase in the number of FNA (R=‒0.853, p=0.007). CONCLUSION: The diagnostic performance of both overall and annual incremental thyroid FNA worsened, whereas the number of thyroid FNA procedures increased. More sophisticated indications for FNA are required to improve its diagnostic efficiency, considering the increased burden of screening-detected thyroid nodules.
