Purpose: Additional surgery is recommended for patients after a non-curative endoscopic submucosal dissection (ESD) to prevent residual cancer (RC) or lymph node metastasis (LNM). We aimed to evaluate the clinicopathologic characteristics of patients who underwent an additional gastrectomy after a non-curative ESD procedure and identify the risk factors of RC and LNM. Methods: We retrospectively assessed the clinicopathological factors of 73 patients who underwent additional gastrectomy following a non-curative ESD between January 2009 and December 2019 at our center. Results: RC and LNM rates after additional gastrectomy were 9.6% and 8.2%, respectively. Invasion deeper than 500 μm (P = 0.045), positive horizontal resection margin (P < 0.001), and positive ESD margin (P = 0.001) were identified as statistically significant factors in univariate analysis for RC, but not in multivariate analysis. Lymphatic invasion was the only risk factor found to be significant in both univariate and multivariate analyses (P = 0.005 and P = 0.012). Conclusion Additional gastrectomy is necessary to prevent RC or LNM after non-curative ESD. Lymphatic invasion was also associated with LNM in patients who underwent an additional gastrectomy after a non-curative ESD, and in such cases, active treatment is required.

The close vicinity of the optic nerve to the sphenoid sinus may cause visual loss in the sphenoid fungus ball. We present a case of blindness secondary to sphenoid fungus ball without any evidence of orbital invasion in imaging studies. A 61-year-old man, suffering from uncomplicated diabetes, was referred for right visual loss that developed 1 day ago. He perceived hand motion on the right. CT and MRI revealed a fungus ball in the right sphenoid sinus. However, there was no evidence of orbital invasion. Endoscopic sphenoethmoidectomy was performed to remove the fungus ball. Systemic mega-dose steroid and amphotericin B were started because he lost the light perception 3 days after surgery. Biopsy revealed aspergillus fungus ball and no evidence of mucosal invasion. However, blindness was not reversed. Evidence of orbital invasion in imaging diagnosis is elusive in sphenoid fungus ball; therefore, systemic antifungal treatment should be initiated and early endoscopic sphenoidotomy should be performed in case of rapidly progressing visual loss, especially in diabetic or immunocompromised patients. Mega-dose steroid therapy for optic neuropathy should be selective because it may aggravate underlying systemic diseases to cause early termination of systemic antifungal treatment.

Intra-abdominal fibromatosis (IAF) may arise either sporadically or in association with familial adenomatous polyposis. The characteristics of fibromatosis are slow-growth, benign histological features, and aggressive local invasion. Surgery remains a reasonable first treatment option. Here, we report 2 cases of a phenomenon rarely described in published literature, IAF after gastrectomy for gastric cancer. Intra-abdominal masses were found during the routine follow-up period in a 50-year-old man who had received a radical subtotal gastrectomy for early gastric cancer. Two mesenteric masses were detected in the upper abdomen by CT and were excised completely along with segments of the jejunum. Another intra-abdominal mass was found in 60-year-old man who had received a radical total gastrectomy for advanced gastric cancer. A 4.2-cm-sized mass was detected in the periumbilical region by follow-up CT and was excised completely along with a segment of the ileum.

Jejunal and ileal diverticula are rare in adults. Duodenal diverticula are five times more prevalent than jejunoileal diverticula. Most patients are asymptomatic. However, chronic symptoms including intermittent abdominal pain, flatulence, diarrhea and constipation are seen in 10%-30% of patients. Gastric cancer is the second most common cancer in South Korea and here we report a case of early gastric cancer with multiple duodenal and jejunal diverticula. A 67-year-old woman was admitted to Konkuk University Medical Center with chronic diarrhea and weight loss of 19 kg over 2 months. Following gastroduodenoscopy, we identified adenocarcinoma of the lower body of the stomach. On abdominopelvic computed tomography, diverticula of duodenum and jejunum were found. Patient underwent distal gastrectomy and gastroduodenostomy with lymphadenectomy. She was discharged on the tenth postoperative day without complications.

PURPOSE: The incidence of abdominal trauma with intra-abdominal organ injury or bowel rupture is increasing. Articles on the diagnosis, symptoms and treatment of small bowel perforation due to blunt trauma have been reported, but reports on the relationship of mortality and morbidity to clinical factors for prognosis are minimal. The purposes of this study are to evaluate the morbidity and mortality of patients with small bowel perforation after blunt abdominal trauma on the basis of clinical examinationand to analyze factors associated with the prognosisfor blunt abdominal trauma with small bowel perforation. METHODS: The clinical data on patients with small bowel perforation due to blunt trauma who underwent emergency surgery from January 1994 to December 2009 were retrospectively analyzed. The correlation of each prognostic factor to morbidity and mortality, and the relationship among prognostic factors were analyzed. RESULTS: A total of 83 patients met the inclusion criteria: The malewas 81.9% .The mean age was 45.6 years.The mean APACHE II score was 5.75.The mean time interval between injury and surgery was 395.9 minutes.The mean surgery time was 111.1 minutes. Forty seven patients had surgery for ileal perforations, and primary closure was done for 51patients. The mean admission period was 15.3 days, and the mean fasting time was 4.5 days. There were 6 deaths (7.2%), and 25 patientssuffered from complications. CONCLUSION: The patient's age and the APACHE II score on admission were important prognostic factors that effecteda patient's progress. Especially, this study shows that the APACHE II score had effect on the operation time, admission period, the treatment period, the fasting time, the mortality rate, and the complication rate.

Background: and Purpose Patients with dementia are particularly vulnerable to coronavirus disease 2019 (COVID-19) because they tend to be older and often have concomitant diseases. Previous studies have investigated the impact of dementia on COVID-19 outcomes, but the evidence is not robust for Asian populations. We aimed to determine the relationship between dementia and COVID-19 outcomes using data from a large-scale nationwide public database. Methods: Data on patients with COVID-19 who were released from quarantine between January 1, 2020 and April 30, 2020, published by the Korea Disease Control and Prevention Agency, were divided into two groups based on the dementia status. Propensity-score matching was used to adjust for multiple confounders between the dementia and no-dementia groups. Binary, ordinal logistic regression and multivariate Cox proportional-hazards models were used to compare mortality, quarantine duration, and clinical deterioration according to the dementia status in the two groups. Results: Males and older individuals (age ≥60 years) constituted 41.5% and 32.9%, respectively, of the 5,299 patients. The prevalence of dementia was 4.2%, and 4.5% of the participants died during hospitalization. In multivariate analysis, dementia was significantly associated with increased mortality (odds ratio [OR]=2.80, 95% confidence interval [CI]=1.60–4.60), longer duration of quarantine (hazard ratio=1.69, 95% CI=1.16–2.45), and larger shift to a worse clinical severity (common OR=1.74, 95% CI=1.18–2.61). Conclusions After adjusting for important clinical predictors, dementia was associated with increased in-hospital mortality, duration of quarantine, and clinical deterioration during hospitalization in COVID-19 patients.

PURPOSE: Preoperative neutrophil-to-lymphocyte ratio (NLR) reflects patients' inflammation status, clinical stage, and survival in various malignancies. However, only a limited amount of information on the clinical importance and prognostic significance of NLR in gastric cancer has been reported. The objective of this study is to assess the prognostic values of preoperative NLR in patients with gastric cancer. METHODS: During the period between August 1, 2005 and December 31, 2011, we collected data from 601 patients among those who had undergone surgery for gastric cancer at the Department of Surgery, Konkuk University Medical Center. We classified the subjects into high NLR (NLR > or = 1.7) group and low NLR (NLR < 1.7) group. RESULTS: The gender, age, and American Society of Anesthesiologists (ASA) score did not differ in the two NLR groups. The pathologic features (tumor size, histology, number of examined lymph node, T stage, N stage, and TNM stage) did not differ either, except for tumor location (P = 0.006). Multivariate analysis identified TNM stage, NLR, and age as significant prognostic factors. Gender, tumor size, location, and histology did not show their prognostic significance when we applied the Cox proportional hazard model. CONCLUSION: Our study verified that advanced stage, high preoperative NLR (NLR > or = 1.7), and old age (> or = 70 years) are significant, independent prognostic factor for overall survival in patients with gastric cancer.

We describe a case of idiopathic CD4+ T-lymphocytopenia (ICL) in a 59-year-old patient who presented with various opportunistic infections. The patient was diagnosed with disseminated Mycobacterium avium infection, cytomegalovirus colitis and retinitis, and esophageal candidiasis. He was successfully treated with anti-mycobacterial drugs, ganciclovir, and fluconazole, respectively. However, the patient was diagnosed with primary central nervous system lymphoma, and then died of a Trichosporon beigelii sepsis during the 2nd cycle of systemic chemotherapy.

Gastric carcinosarcoma is an uncommon biphasic malignant tumor. We report the case of 59-year-old man with a history of melena and dizziness. Endoscopic findings showed a fungating mass that originated from the posterior wall of upper body. Radical total gastrectomy with Roux-en-Y esophagojejunostomy was performed. In the resected specimen, immunohistochemical studies for epithelial and mesenchymal markers showed positive reactions. The mass invaded the submucosa without regional lymph node metastasis. Adjuvant chemotherapy with TS-1 (Taiho Pharmaceutical Co. Ltd, Japan) was performed after surgery despite early clinical stage due to aggressive features of carcinosarcoma.

Langerhans cell histiocytosis (LCH) is a rare histiocytic disorder characterized by heterogenous lesions infiltrated with CD1a+/CD207+ cells. Although LCH has a relatively good prognosis, the prognosis for patients with LCH refractory to standard chemotherapy is poor. Neurodegenerative LCH (ND-LCH) is a central nervous system complication of LCH that is characterized by progressive radiological and clinical abnormalities. Symptomatic ND-LCH is difficult to treat and therefore has a poor prognosis. A two-year-old boy presented with a scalp mass. Biopsy confirmed LCH. Whole-body imaging revealed LCH involvement in multiple bones of the skull, facial bones, and lungs. Prednisolone and vinblastine chemotherapy was initiated. One-year post-treatment, most of the lesions in the bones and lung nodules disappeared, and chemotherapy was discontinued. New neurodegenerative lesions appeared 4 months after chemotherapy was discontinued. Second-line chemotherapy using cytarabine, vincristine, and prednisolone was initiated. However, neurological manifestations of ND-LCH worsened post second-line treatment, and the treatment was switched to cytarabine and cladribine. Despite third-line chemotherapy, the lesions progressed, and neurological deficits worsened. After identifying BRAF V600E mutation in the tumor tissue using next-generation sequencing, cytotoxic chemotherapy was discontinued and vemurafenib treatment was initiated. One-year post-vemurafenib therapy, ND-LCH manifestations regressed, and the patient experienced neurological improvement.
