ABSTRACT

Non-celiac gluten sensitivity (NCGS) is a term that is used to describe individuals who are not affected by celiac disease or wheat allergy, yet they have intestinal and/or extra-intestinal symptoms related to gluten ingestion with improvement of their symptoms upon withdrawing gluten from their diet. Gluten-related disorder groups are manifested by symptoms of gastrointestinal tract disorders, as well as hematological dermatological endocrinological, gynecological, rheumatological and nervous system symptoms. It is believed that NCGS represents heterogeneous groups with different subgroups characterized by different etiologies, clinical histories and clinical courses. There also appears to be an overlap between NCGS and irritable bowel syndrome (IBS). There is a need for establishing strict criteria for diagnosing NCGS. The absence of validated biomarkers remains a significant limitation for research studies on NCGS. New evidence shows that a gluten-free diet may be beneficial for some patients with gastrointestinal symptoms, such as those symptoms commonly found in patients with IBS. Further studies about NCGS are needed.

ABSTRACT

Small cell carcinomas are the most aggressive, highly malignant neuroendocrine tumors; among these, gastric small cell carcinoma (GSCC) is extremely rare. Here we report a case of a patient with primary GSCC, presenting as linitis plastic, who was diagnosed using endoscopic ultrasound (EUS)-guided biopsy. With undiagnosed linitis plastica, an 80-year-old woman was referred to our institution. Abdominal computed tomography revealed irregular wall thickening extending from the gastric body to the antrum. Endoscopy suspected to have Borrmann type IV advanced gastric cancer. EUS of the stomach showed diffuse submucosal thickening of the gastric wall, mainly the antrum. EUS-guided bite-on-bite biopsy confirmed the diagnosis of GSCC. In general, GSCC is difficult to diagnose and careful examination is necessary to determine the therapeutic strategy; however, EUS is particularly helpful in the differential diagnosis of a lesion presenting as linitis plastica.

ABSTRACT

Irritable bowel syndrome (IBS) is a common, chronic functional gastrointestinal disorder affecting the large intestine, and presents as abdominal pain and/or discomfort, bloating, gas retention, diarrhea, and constipation. IBS impairs quality-of-life and requires long-term management. In 2016, the Rome Foundation introduced new IBS diagnostic criteria (the Rome IV criteria), and also revised the diagnostic algorithms for, and the multidimensional clinical profile (MDCP) of, functional gastrointestinal disorders. The IBS MDCP includes clinical data, the extent to which normal daily activities are affected, and psychosocial and physiological measures. The criteria seek to aid physicians in choosing appropriate treatment for IBS patients. Herein, we seek to provide evidence- based practical information on IBS and functional diarrhea. We review the new Rome diagnostic IV criteria, the MDCP, and the various IBS treatment options. We suggest that, in clinical practice, combination therapies may be useful to treat patients with IBS of various grades.

ABSTRACT

Perivascular epithelioid cell tumors (PEComas) are unusual mesenchymal neoplasms composed of histologically and immunohistochemically distinct perivascular epithelioid cells (PECs). Although PEComas have the potential to behave in a malignant fashion, malignant PEComas arising from the retroperitoneum are extremely rare. A 68-year-old woman presented with a painful palpable mass in her left upper abdomen. Computed tomography of the abdomen showed a 9 cm sized heterogeneous mass in left para-aortic space and multiple hypervascular nodules in the liver. 18F-fludeoxyglucose-PET/CT showed multifocal hypermetabolic lesions in retroperitoneum, liver, and skeletal bones. Percutaneous needle biopsies were done on the retroperitoneal and hepatic mass. Both specimens were positive for human melanoma black-45 (HMB-45) on histological and immunohistochemical staining which was compatible with PEComas. Herein, we report a rare case of retroperitoneal PEComa with multiple metastases involving liver and bone at initial diagnosis that exhibited aggressive behavior and resulted in a devastating prognosis.

ABSTRACT

BACKGROUND/AIMS: Differentiating subepithelial tumor (SET) from non-neoplastic gastrointestinal subepithelial lesion (SEL) and gastrointestinal stromal tumor (GIST) from leiomyoma are very important for proper management. This study was conducted to analyze factors that could predict the presence of SET and GIST in patients with upper gastrointestinal (UGI) SELs. METHODS: A total of 527 patients were diagnosed with UGI SELs endosonographically at Gyeongsang National University Hospital from January 2008 to June 2013. Among these patients, histologic diagnosis was made in 84 patients. Data were collected by retrospectively reviewing the medical records. Variables that could differentiate neoplastic from non-neoplastic SELs and GIST from leiomyoma were analyzed. RESULTS: Among 84 patients with SELs, 64 (76.2%) had SETs including GIST (42.9%) and leiomyoma (19.0%). The patients' mean age (p=0.047), peak age distribution (p=0.047), proportions of patient > or =50 years (p=0.015), and number of proper muscle-originated lesions (p=0.001) were higher in neoplastic than non-neoplastic group. There were no significant differences in gender (p=0.195), size (p=0.266) and echogenicity (p=0.051) of the lesions. Older age (57.7 vs. 47.0 years, p=0.049), age > or =50 years (p=0.016), location in gastric body (p or =50 years, size > or =30 mm, and proper muscle-origin of lesion were independent predictors of SET; however, there were no predictive factors that could differentiate GIST from leiomyoma. CONCLUSIONS: In patients with SEL, the possibility of having SET should be considered for patients > or =50 years with UGI SELs > or =30 mm that arise from the proper muscle. Thorough monitoring and aggressive management is warranted for those with gastric muscular SET since factors predictive of GIST are lacking.

ABSTRACT

Liver cirrhosis is commonly associated with bleeding complications due to portal hypertension or coagulopathy. Spontaneous muscle hematoma is a rare but potentially lethal complication of liver cirrhosis. Here we report three cases of spontaneous muscle hematoma diagnosed in patients with alcoholic liver cirrhosis. All three patients died due to recurrent bleeding and liver failure although they had undergone repeated transcatheter arterial embolization of the actively bleeding vessels. We reviewed 14 cases of spontaneous muscle hematoma that were associated with liver cirrhosis, including our cases, and found that the mortality rate was 86%, despite early diagnosis and treatment. Cirrhosis-associated spontaneous muscle hematoma occurred more frequently in patients with alcoholic liver cirrhosis, who accounted for -93% of cases. Thus, spontaneous muscle hematoma should be considered a life-threatening complication in patients with alcoholic liver cirrhosis, and abstinence from alcohol may help to prevent the occurrence of this deadly condition.

ABSTRACT

Esophageal carcinosarcoma is a rare malignant esophageal neoplasm consisting of both carcinomatous and sarcomatous elements, with an incidence of 0.5%. There have been only a few case reports of carcinosarcoma and squamous cell carcinoma coexisting in the esophagus. However, all of these are cases of synchronous or metachronous development of carcinosarcoma after chemoradiotherapy in patients of esophageal squamous cell carcinoma. A 53-year-old man underwent esophagogastroduodenoscopy because of chest pain for several months. Endoscopic examination revealed a huge pedunculated esophageal polypoid mass. Endoscopic submucosal dissection (ESD) was performed and histopathologic examination confirmed spindle cell carcinoma (carcinosarcoma). He refused additional esophagectomy. After 21 months, third follow-up endoscopy showed poorly-demarcated flat, faint discolored lesions at different location from the previous ESD site and endoscopic biopsies confirmed squamous cell carcinoma. To the best of our knowledge, this is the first case of metachronous development of esophageal squamous cell carcinoma in a patient with esophageal carcinosarcoma.

ABSTRACT

Transcatheter arterial chemoembolization (TACE) has become an effective alternative treatment strategy for patients with inoperable hepatocellular carcinoma (HCC). Although TACE is relatively safe, acute respiratory distress syndrome associated with pulmonary lipiodol embolism is a rare and potentially fatal complication. We report a rare case of acute respiratory distress syndrome after TACE for inoperable HCC. A 75-year-old man, with huge HCC in right lobe, was treated by TACE for the first time. Seven hours after uneventful TACE procedure, he felt dyspneic and his oxygen saturation recorded by pulse oximetry (SpO2) fell to 80% despite of applying non-rebreathing mask. He underwent mechanical ventilation with a protective ventilatory strategy. We experienced a case of acute respiratory distress syndrome after TACE for HCC.
