ABSTRACT

Background/Aims@#Endoscopic submucosal dissection is a widely used treatment for gastric epithelial neoplasms. Accurate delineation of the horizontal margins is necessary for the complete resection of gastric epithelial neoplasms. Recently, image-enhanced endoscopy has been used to evaluate horizontal margins of gastric epithelial neoplasms. The aim of this study was to investigate whether I-SCAN-optical enhancement (I-SCAN-OE) is superior to chromoendoscopy in evaluating the horizontal margin of gastric epithelial neoplasms. @*Methods@#This was a multicenter, prospective, and randomized trial. The participants were divided into two groups: I-SCAN-OE and chromoendoscopy. For both groups, we first evaluated the horizontal margins of early gastric cancer or high-grade dysplasia using white-light imaging, and then evaluated, the horizontal margins using I-SCAN-OE or chromoendoscopy. We devised a unique scoring method based on the pathological results obtained after endoscopic submucosal dissection to accurately evaluate the horizontal margins of gastric epithelial neoplasms. The delineation scores of both groups were compared, as were the ratios of positiveegative horizontal margins. @*Results@#In total, 124 patients were evaluated for gastric epithelial neoplasms, of whom 112 were enrolled in the study. A total of 112 patients participated in the study, and 56 were assigned to each group (1:1). There was no statistically significant difference in the delineation scores between the groups (chromoendoscopy, 7.80±1.94; I-SCAN-OE, 8.23±2.24; p=0.342). @*Conclusions@#I-SCAN-OE did not show superiority over chromoendoscopy in delineating horizontal margins of gastric epithelial neoplasms.

ABSTRACT

Inflammatory pseudotumor (IPT) is a rare benign tumor of unknown etiology that can occur in almost any organ system. It has neoplastic features such as local recurrence, invasive growth, and vascular invasion, leading to the possibility of malignant sarcomatous changes. The clinical presentations of colonic IPT may include abdominal pain, anemia, a palpable mass, and intestinal obstruction. A few cases of colonic IPT have been reported, but colonic IPT with pedunculated morphology is very rare. Furthermore, since it can mimic malignant polyps, understanding the endoscopic findings of colonic IPT is important for proper treatment. Herein, we present a case of colonic IPT with pseudosarcomatous changes, presenting as a large polyp, mimicking a malignant polyp in the cecum, along with a literature review.

ABSTRACT

Pleurisy is an inflammation of the parietal pleura and is characterized by pleuritic pain. The most common cause of pleurisy is infection; other causes include rheumatoidarthritis, malignancy, rib fractures, or trauma. Possible causes of chest pain associated withgolf include costochondritis, stress fractures of the ribs, intercostal muscle strain, or, rarely,Tietze’s syndrome and slipping rib syndrome.Case: A 64-year-old female presented with intractable chest pain that began 4 months priorwhile playing golf. No specific cause was found after various examinations. There was persistent pain despite medical treatment. Ultrasonography (US) was performed over the painful areas, which revealed focal pleural effusions. A mixture of ropivacaine and triamcinolonewas injected into the focal pleural effusions using US guidance, which dramatically relievedher pain.Conclusions: This case demonstrates that US can be used as a diagnostic and therapeuticmodality for intractable chest pain with an undetected pathology.

ABSTRACT

Purpose@#The appropriate evaluation of height and accurate estimation of bone age are crucial for proper assessment of the growth status of a child. We developed a bone age estimation program using a deep learning algorithm and established a model to predict the final adult height of Korean children. @*Materials and Methods@#A total of 1678 radiographs from 866 children, for which the interpretation results were consistent between two pediatric endocrinologists, were used to train and validate the deep learning model. The bone age estimation algorithm was based on the convolutional neural network of the deep learning system. The test set simulation was performed by a deep learning program and two raters using 150 radiographs and final height data for 100 adults. @*Results@#There was a statistically significant correlation between bone age interpreted by the artificial intelligence (AI) program and the reference bone age in the test set simulation (r=0.99, p<0.001). In the test set simulation, the AI program showed a mean absolute error (MAE) of 0.59 years and a root mean squared error (RMSE) of 0.55 years, compared with reference bone age, and showed similar accuracy to that of an experienced pediatric endocrinologist (rater 1). Prediction of final adult height by the AI program showed an MAE of 4.62 cm, compared with the actual final adult height. @*Conclusion@#We developed a bone age estimation program based on a deep learning algorithm. The AI-derived program demonstrated high accuracy in estimating bone age and predicting the final adult height of Korean children and adolescents.

ABSTRACT

Purpose@#We report a case of probable posterior ischemic optic neuropathy in a patient with acute fungal sinusitis.Case Summary: An 81-year-old male patient presented with sudden-onset visual loss in his left eye 3 weeks prior to presentation. His best corrected visual acuity was 0.6 in his right eye and light perception in his left eye. Pupillary size was 3 mm in both eyes, and a relative afferent pupillary defect was detected in his left eye. In fundus examination, diabetic retinopathy was found, and cup/disc ratios were increased in both eyes, but disc swelling and hemorrhage were not observed. Fluorescein angiography did not indicate filling delay, defects, or leakage of discs in either eye. Magnetic resonance imaging of the brain revealed multi-sinusitis in the sphenoid, ethmoid, and frontal sinuses. No bony defects or erosion were found around the optic canal or orbital apex during endoscopic surgery; however, histological examination revealed aspergillosis. The patient was diagnosed with posterior ischemic optic neuropathy caused by acute fungal sinusitis. @*Conclusions@#When elderly patients with uncontrolled diabetes experience sudden visual disturbances without ocular pain, posterior ischemic optic neuropathy with fungal sinusitis should be considered as a differential diagnosis. Immediate imaging studies and appropriate treatment should be performed.

ABSTRACT

In recent years, advancements in information and communication technologies, including artificial intelligence, big data, virtual reality, and augmented reality, have driven substantial growth in the field of digital medical diagnosis and treatment, thereby enhancing quality of life. Beginning in the mid-2010s with the advent of digital healthcare applications, and further accelerated by the impact of coronavirus disease 2019, digital therapeutic products have profoundly influenced society. Nevertheless, the expansion of digital therapeutics has encountered challenges associated with regulatory hurdles, differentiation from general digital healthcare, and the necessity for trustworthiness, which have contributed to a slower rate of progress. This study proposes a 3P content model–encompassing pre-education, prediction/diagnosis/treatment, and postmanagement–to increase the trustworthiness of digital therapeutics. The design of the 3P content model includes a fundamental structure that establishes networks with healthcare institutions, aiming to increase the reliability of data utilization and to facilitate integration with medical decision support systems. For case development, the study introduces a prototype of a mobile application that utilizes chronic disease urinary dysfunction data, demonstrating the cyclical structure inherent in the 3P content model.

ABSTRACT

Purpose@#As thyroid cancer patients are experiencing longer disease-free survival periods, evaluating their quality of life after surgery has become crucial. However, studies on this topic have primarily focused on Western populations, leaving a gap in understanding the Korean patient population’s experiences and needs. This study aims to address this gap and provide insights into the quality of life of thyroid cancer patients in Korea. @*Methods@#This cross-sectional study evaluated the quality of life of Korean thyroid cancer patients who underwent thyroid lobectomy or total thyroidectomy. Patients were surveyed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30, ver. 3.0) during outpatient clinic visits from January to September 2015. The results were analyzed by comparing them to scores of the general population and based on the time elapsed since surgery. This approach allowed for a comprehensive evaluation of the quality-of-life outcomes in this patient population. @*Results@#The study found that thyroidectomy had a notable impact on patients’ role and cognitive functions. Patients also experienced worsened symptoms such as fatigue, dyspnea, and constipation, which improved over time and returned to normal levels. However, there were no significant changes in other functions and symptoms after surgery. @*Conclusion@#The study’s findings showed that thyroidectomy had a relatively minor impact on the functional and symptomatic well-being of patients. Therefore, the results suggest that thyroid surgery may be a safe and effective treatment option for thyroid cancer patients seeking to maintain a good quality of life.

ABSTRACT

The Committee of Central Precocious Puberty of Korean Pediatrics and Adolescents of the Korean Society of Pediatric Endocrinology has newly developed evidence-based 2022 clinical practice guidelines for central precocious puberty in Korean children and adolescents. These guidelines provide the grade of recommendations, which includes both the strength of recommendations and the level of evidence. In the absence of sufficient evidence, recommendations are based on expert opinion. These guidelines have been revised and supplement the previous guidelines "Clinical Guidelines for Precocious Puberty 2011," and are drawn from a comprehensive review of the latest domestic and international research and the grade of recommendation appropriate to the domestic situation. This review summarizes the newly revised guidelines into 8 key questions and 27 recommendations and consists of 4 sections: screening, diagnosis, treatment, and long-term outcome of central precocious puberty.

ABSTRACT

Purpose@#We aimed to investigate the prevalences of obesity, abdominal obesity, and non-alcoholic fatty liver disease (NAFLD) among children and adolescents during the coronavirus disease 2019 (COVID-19) outbreak. @*Materials and Methods@#This population-based study investigated the prevalences of obesity, abdominal obesity, and NAFLD among 1428 children and adolescents between 2018–2019 and 2020. We assessed the prevalences of obesity, abdominal obesity, and NAFLD according to body mass index, age, sex, and residential district. Logistic regression analyses were performed to determine the relationships among obesity, abdominal obesity, and NAFLD. @*Results@#In the obese group, the prevalence of abdominal obesity increased from 75.55% to 92.68%, and that of NAFLD increased from 40.68% to 57.82%. In age-specific analysis, the prevalence of abdominal obesity increased from 8.25% to 14.11% among participants aged 10–12 years and from 11.70% to 19.88% among children aged 13–15 years. In residential district-specific analysis, the prevalence of both abdominal obesity and NAFLD increased from 6.96% to 15.74% in rural areas. In logistic regression analysis, the odds ratio of abdominal obesity for NAFLD was 11.82. @*Conclusion@#Our results demonstrated that the prevalences of abdominal obesity and NAFLD increased among obese Korean children and adolescents and in rural areas during the COVID-19 outbreak. Additionally, the prevalence of abdominal obesity increased among young children. These findings suggest the importance of closely monitoring abdominal obesity and NAFLD among children during COVID-19, focusing particularly on obese young children and individuals in rural areas.

ABSTRACT

Background/Aims@#Some sessile serrated lesions (SSLs) progress into dysplasia and colorectal cancer, however, the clinical and endoscopic characteristics of SSLs with dysplasia remain to be determined. In this study, we elucidated these characteristics in SSLs with dysplasia/carcinoma, compared with those of SSLs without dysplasia. @*Methods@#We retrospectively collected the clinical, endoscopic, and pathological data of 254 SSLs from 216 patients endoscopically resected between January 2009 and December 2020. @*Results@#All SSLs included 179 without dysplasia and 75 with dysplasia/carcinoma, including 55 with low-grade dysplasia, 10 with high-grade dysplasia, and 10 with submucosal cancer. In clinical characteristics, SSLs with dysplasia/carcinoma were significantly associated with advanced age, metabolic diseases, and high-risk adenomas. In endoscopic characteristics, SSLs with dysplasia/carcinoma were significantly associated with the distal colon, large size, polypoid morphology, surface-changes, no mucus cap, and narrow-band imaging international colorectal endoscopic classification (NICE) type 2/3. In the multivariate analysis, high-risk adenomas (odds ratio [OR], 2.98; p = 0.01), large size (OR, 1.18; p < 0.01), depression (OR, 11.74; p = 0.03), and NICE type 2/3 (OR, 14.97; p < 0.01) were significantly associated with SSLs with dysplasia/carcinoma. @*Conclusions@#SSLs had a higher risk of dysplasia in the distal colon than in the proximal colon. SSLs with large size, depression, and adenomatous surface-patterns, as well as those in patients with high-risk adenomas, increased the risk of dysplasia/ carcinoma. This suggests that the clinical and endoscopic characteristics can aid in the diagnosis and management of SSLs with dysplasia/carcinoma.

ABSTRACT

Purpose@#This study investigated the actual incidence of acute poisoning in Korea on a nationwide scale, with the aim of laying the groundwork for future initiatives in prevention, strategic antidote distribution, and the development of effective emergency treatment for acute poisoning. @*Methods@#The study analyzed data from 3,038 patients who presented to emergency departments with poisoning-related conditions from June 1, 2022 to December 31, 2022 at 10 sites in nine cities across the country. We extracted data on general characteristics of the poisoning cases, including demographic characteristics (age and gender), place of exposure, reason for poisoning, route of exposure, and the substance involved in the poisoning incident. Age-related patterns in reasons for poisoning, medical outcomes, frequent and primary poisoning substances, and deaths were also analyzed. @*Results@#The population analyzed in our study was predominantly female, with women constituting 54.74% of all cases. Among infants and children, non-intentional poisoning due to general accidents was the most common cause, accounting for 71.43% of cases. Conversely, suicidal poisoning was more prevalent among teenagers and adults over 20. Fifty-two patients died during the study period, with males comprising approximately two-thirds (67.31%) of these fatalities. Pesticides were the most common poisoning substance among those who died, accounting for 55.77% of such cases. Notably, a significant majority of the victims were elderly individuals aged 60 and above. @*Conclusion@#This study holds substantial significance, since it represents the first comprehensive investigation and analysis of the symptoms, treatment, and causes of death due to poisoning in Korea on a national scale. By substantially expanding the range and types of poisonous substances examined, we were able to more precisely identify the characteristics and clinical patterns of poisoning cases nationwide.

ABSTRACT

Purpose@#The Korea University Anam Hospital Seoul Poison Control Center (SeoulPCC) was established in accordance with Seoul Metropolitan Government Ordinance No. 7524 “Seoul Metropolitan Government Ordinance on the Prevention of Toxic Substances Poisoning and Accident Safety.” Herein, the center’s annual performance in terms of project results and consultation information for 2022 are reported. @*Methods@#SeoulPCC operates a helpline (Help Call, 1855-2221) that the general public can use from 9:00 AM to 5:00 PM on weekdays, as well as chatting and chatbot counseling through KakaoTalk’s “Seoul Poison Control Center,” and one-on-one online counseling through the website. Additionally, it has constructed a system for communicating with the general public through social media. Poisoning disease information collected from SeoulPCC from January to December 2022 was analyzed according to the number of requests, age of exposure, gender, location, and reason. Requests from the general public were summarized, and a brief image presenting information on poisoning disease-related consultations was produced. @*Results@#SeoulPCC has a database containing information on 188,065 toxic substances collected by public institutions and provides this information to the general public and medical staff through its website. In 2022, consultations were performed through phone calls and SNS (social networking service) for 577 cases of poison information and first aid treatment due to exposure to toxic substances. There were 1,431 instances of providing poison information services. The annual requests included 512 exposure cases and 65 non-exposure cases. Furthermore, 366 cases were in Seoul, 145 cases were outside of Seoul, and 66 had an unknown location. The exposure cases included 161 requests from the general public and 351 requests from medical staff. @*Conclusion@#This is the first annual report in Korea to analyze the occurrence of poisoning based on consultations. It is of major significance that this report serves as a starting point for identifying and tracking the aspects and characteristics of poisoning cases in the pre-hospital stage. In the future, poisoning-related disease information provided through consultations and at the emergency room should be linked, and through real-time collection and analysis, this information should be used as basic data for poisoning disease management policies.

ABSTRACT

Background/Aims@#Transcatheter arterial embolization (TAE) is useful for management of uncontrolled upper gastrointestinal (UGI) bleeding. We investigated clinical outcomes of TAE for non-variceal bleeding from benign UGI diseases uncontrolled with endoscopic intervention. @*Methods@#This retrospective study performed between 2017 and 2021 across four South Korean hospitals. Ninety-two patients (72 men, 20 women) who underwent angiography were included after the failure of endoscopic intervention for benign UGI disease- induced acute non-variceal bleeding. We investigated the factors associated with endoscopic hemostasis failure, the technical success rate of TAE, and post-TAE 30-day rebleeding and mortality rates. @*Results@#The stomach (52/92, 56.5%) and duodenum (40/92, 43.5%) were the most common sites of bleeding. Failure of endoscopic procedures was attributable to peptic ulcer disease (81/92, 88.0%), followed by pseudo-aneurysm (5/92, 5.4%), and angiodysplasia (2/92, 2.2%). Massive bleeding that interfered with optimal visualization of the endoscopic field was the most common indication for TAE both in the stomach (22/52, 42.3%) and duodenum (14/40, 35.0%). Targeted TAE, empirical TAE, and exclusive arteriography were performed in 77 (83.7%), nine (9.8%), and six patients (6.5%), respectively. The technical success rate, the post-TAE 30-day rebleeding rate, and the overall mortality rate were 100%, 22.1%, and 5.8%, respectively. On multivariate analysis, coagulopathy (OR, 5.66; 95% CI, 1.71~18.74; P=0.005) and empirical embolization (OR, 5.71; 95% CI, 1.14~28.65; P=0.034) were independent risk factors for post-TAE 30-day rebleeding episodes. @*Conclusions@#TAE may be useful for acute non-variceal UGI bleeding. Targeted embolization and correction of coagulopathy can improve clinical outcomes.

ABSTRACT

In vivo molecular imaging is a research field in which molecular biology and advanced imaging techniques are combined for imaging molecular-level biochemical and physiological changes that occur in a living body. For biomolecular imaging, the knowledge of molecular biology, cell biology, biochemistry, and physiology must be applied. Imaging techniques such as fluorescence, luminescence, single-photon emission computed tomography (SPECT), positron emission tomography (PET), computed tomography (CT), and magnetic resonance imaging (MRI) are used for biomolecular imaging. These imaging techniques are used in various fields, i.e., diagnosis of various diseases, development of new drugs, development of treatments, and evaluation of effects. Moreover, as biomolecular imaging can repeatedly acquire images without damaging biological tissues or sacrificing the integrity of objects, changes over time can be evaluated. Phenotypes or diseases in a living body are caused by the accumulation of various biological phenomena. Genetic differences cause biochemical and physiological differences, which accumulate and cause anatomical or structural changes. Biomolecular imaging techniques are suitable for each step. In evaluating anatomical or structural changes, MRI, CT, and ultrasound have advantages in obtaining high-resolution images. SPECT and MRI are advantageous for the evaluation of various physiological phenomena. PET and magnetic resonance spectroscopy can be used to image biochemical phenomena in vivo. Although various biomolecular imaging techniques can be used to evaluate various biological phenomena, it is important to use imaging techniques suitable for each purpose.

ABSTRACT

Background@#Cross-talk between mitogen-activated protein kinase and estrogen has been reported; however, the role of BRAFV600E in the estrogen responsiveness of thyroid cancer is unknown. We elucidated the effect of BRAFV600E on the estrogen-induced increase in metastatic potential in thyroid cancer. @*Methods@#Using a pair of cell lines, human thyroid cell lines which harbor wild type BRAF gene (Nthy/WT) and Nthy/BRAFV600E (Nthy/V600E), the expression of estrogen receptors (ERs) and estrogen-induced metastatic phenotypes were evaluated. Susceptibility to ERα- and ERβ-selective agents was evaluated to confirm differential ER expression. ESR expression was analyzed according to BRAFV600E status and age (≤50 years vs. >50 years) using The Cancer Genome Atlas (TCGA) data. @*Results@#Estradiol increased the ERα/ERβ expression ratio in Nthy/V600E, whereas the decreased ERα/ERβ expression ratio was found in Nthy/WT. BRAFV600E-mutated cell lines showed a higher E2-induced increase in metastatic potential, including migration, invasion, and anchorage-independent growth compared with Nthy/WT. An ERα antagonist significantly inhibited migration in Nthy/V600E cells, whereas an ERβ agonist was more effective in Nthy/WT. In the BRAFV600E group, ESR1/ESR2 ratio was significantly higher in younger age group (≤50 years) compared with older age group (>50 years) by TCGA data analysis. @*Conclusion@#Our data show that BRAFV600E mutation plays a crucial role in the estrogen responsiveness of thyroid cancer by regulating ER expression. Therefore, BRAFV600E might be used as a biomarker when deciding future hormone therapies based on estrogen signaling in thyroid cancer patients.

ABSTRACT

Purpose@#Postoperative adhesions after thyroidectomy adversely affect patients’ quality of life. This study assessed the anti-adhesive effect and safety of thermosensitive sol-gel agents for patients undergoing thyroidectomy. @*Methods@#A double-blind parallel-group randomized clinical trial involving patients aged 20–70 years undergoing thyroidectomy for thyroid nodules was conducted. From August 2017 to April 2020, 90 patients were randomly assigned to the experimental (n = 45, thermosensitive sol-gel agent applied to the surgical site) and control (n = 45, no treatment) groups in a 1:1 ratio. All patients were assessed using a questionnaire for swallowing difficulty, wrinkle problems, and inflammation at 2 weeks, 3 months, and 6 months after thyroid surgery. For reoperated patients, the degree of adhesion was evaluated according to the adhesion-evaluation score system (range, 0–4). @*Results@#During the follow-up period of 6.50 ± 1.38 months, the swallowing difficulty, wrinkle problem, and inflammation were improved in both groups. However, there was no statistically significant difference between the control and experimental groups related to swallowing difficulty, wrinkle problems, and inflammation. Two patients in the control group and 1 in the experimental group who underwent reoperation had an adhesion-evaluation score of 3 points. There were no adverse effects or allergic reactions. @*Conclusion@#A thermosensitive sol-gel agent can be safely used as an anti-adhesive barrier. However, this study did not reveal its efficacy for postoperative adhesions. A more objective and systematic study is required in the future.

ABSTRACT

Purpose@#Overactive bladder (OAB) is observed in women with functional bladder outlet obstruction (FBOO), as are lower urinary tract symptoms (LUTS). Therefore, we evaluated the urodynamic characteristics of women with storage LUTS and FBOO diagnosed by urodynamic studies (UDS). @*Methods@#Women (n=108) with storage LUTS and FBOO diagnosed by UDS were included in this study. The urodynamic characteristics of women with FBOO were compared with those of women with OAB (n=34) and stress urinary incontinence (SUI, n=78). FBOO was defined as a maximum flow rate (Qmax) 20 cm H2O in a pressure-flow study. The UDS included uroflowmetry, postvoid residual volume determination, a cystometrogram, and a pressure-flow study. @*Results@#Women with FBOO who had storage symptoms showed a higher PdetQmax and maximum urethral closing pressure (MUCP) than women with OAB and SUI. Interstitial cystitis/bladder pain syndrome (IC/BPS) was observed in 17.6% of women with FBOO. MUCP was significantly higher in women with BOO than in women with BOO and IC/BPS (115.6±27.4 and 96.6±14.1 cm H2O, P=0.00). The receiver operating characteristic curve analysis showed that the cutoff values of MUCP in women with FBOO compared to women with OAB and SUI were 87 cm H2O (sensitivity=81.5%, specificity=73.5%) and 36 cm H2O (sensitivity=92.6%, specificity=84.4%), respectively. The cutoff value of MUCP in women with FBOO compared to women with FBOO and IC/BPS was 92 cm H2O (sensitivity=85.4%, specificity=78.9%). @*Conclusions@#MUCP could have predictive value for identifying FBOO in women with complex LUTS.

ABSTRACT

Background@#Optimal management of primary aldosteronism (PA) is crucial due to the increased risk of cardiovascular and cerebrovascular diseases. Adrenal venous sampling (AVS) is the gold standard method for determining subtype but is technically challenging and invasive. Some PA patients do not benefit clinically from surgery. We sought to develop an algorithm to improve decision- making before engaging in AVS and surgery in clinical practice. @*Methods@#We conducted the ongoing Korean Primary Aldosteronism Study at two tertiary centers. Study A involved PA patients with successful catheterization and a unilateral nodule on computed tomography and aimed to predict unilateral aldosterone-producing adenoma (n=367). Study B involved similar patients who underwent adrenalectomy and aimed to predict postoperative outcome (n=330). In study A, we implemented important feature selection using the least absolute shrinkage and selection operator regression. @*Results@#We developed a unilateral PA prediction model using logistic regression analysis: lowest serum potassium level ≤3.4 mEq/L, aldosterone-to-renin ratio ≥150, plasma aldosterone concentration ≥30 ng/mL, and body mass index <25 kg/m2 (area under the curve, 0.819; 95% confidence interval, 0.774 to 0.865; sensitivity, 97.6%; specificity, 25.5%). In study B, we identified female, hypertension duration <5 years, anti-hypertension medication <2.5 daily defined dose, and the absence of coronary artery disease as predictors of clinical success, using stepwise logistic regression models (sensitivity, 94.2%; specificity, 49.3%). We validated our algorithm in the independent validation dataset (n=53). @*Conclusion@#We propose this new outcome-driven diagnostic algorithm, simultaneously considering unilateral aldosterone excess and clinical surgical benefits in PA patients.

ABSTRACT

Purpose@#This study aimed to evaluate the cumulative recurrence rate and risk factors for recurrent abdominal wall endometriosis (AWE) after surgical treatment. @*Materials and Methods@#A retrospective cohort study was conducted at a single gynecological surgery center between January 2004 and December 2020. Patients who were surgically treated and followed up for at least 6 months after surgery were selected. @*Results@#Eighteen patients with pathologically diagnosed AWE were included in this study. The median follow-up duration was 22.5 months (range, 6–106). The median age was 37 years (range, 22–48), and 33.3% of the patients were nulliparous. Among the patients included in our study, 55.6% complained of a mass with cyclic pain, and 27.8% had a palpable mass. In addition, 22.2% of patients experienced recurrence with 17.5±9.7 months of mean time to recurrence. The cumulative recurrence rates at 24 and 60 months after surgical treatment of AWE were 23.8% and 39.1%, respectively. There were no statistically significant risk factors for the recurrence of AWE, including postoperative medical treatment. @*Conclusion@#The recurrence rate of AWE appears to be correlated with the follow-up duration. There was no statistically significant risk factor for the recurrence of AWE. Unlike ovarian endometriosis, postoperative hormonal treatment does not seem to lower the recurrence of AWE. The findings of the current study may help healthcare providers in counselling and managing patients with AWE.

ABSTRACT

Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated esophageal disease characterized by symptoms of esophageal dysfunction and eosinophil-predominant inflammation. The diagnostic criteria for EoE have changed with our growing knowledge over the past two decades. Esophageal eosinophilia, which responds histologically to a proton pump inhibitor (PPI) is not a distinct disease but a subset of EoE. An endoscopic scoring system that relies on the assessment of exudates, rings, edema, furrows, and strictures is a useful tool for assessing endoscopic severity. PPIs are regarded as safe and effective first-line treatments for EoE. Oral topical corticosteroids or dietary therapy are also options for first-line treatment. Endoscopic dilation is effective for relieving the dysphagia symptoms of a patient with an esophageal stricture.
