Adherence to Surveillance Guidelines after the Removal of Colorectal Polyps: A Multinational, Multicenter, Prospective Survey

Background/Aims@#As the number of colonoscopies and polypectomies performed continues to increase in many Asian countries, there is a great demand for surveillance colonoscopy. The aim of this study was to investigate the adherence to postpolypectomy surveillance guidelines among physicians in Asia. @*Methods@#A survey study was performed in seven Asian countries. An email invitation with a link to the survey was sent to participants who were asked to complete the questionnaire consisting of eight clinical scenarios. @*Results@#Of the 137 doctors invited, 123 (89.8%) provided valid responses. Approximately 50% of the participants adhered to the guidelines regardless of the risk of adenoma, except in the case of tubulovillous adenoma ≥10 mm combined with high-grade dysplasia, in which 35% of the participants adhered to the guidelines. The participants were stratified according to the number of colonoscopies performed: ≥20 colonoscopies per month (high volume group) and <20 colo-noscopies per month (low volume group). Higher adherence to the postpolypectomy surveillance guidelines was evident in the high volume group (60%) than in the low volume group (25%). The reasons for nonadherence included concern of missed polyps (59%), the low cost of colonoscopy (26%), concern of incomplete resection (25%), and concern of medical liability (15%). @*Conclusions@#A discrepancy between clinical practice and surveillance guidelines among physicians in Asia was found. Physicians in the low volume group frequently did not adhere to the guidelines, suggesting a need for continuing education and appropriate control. Concerns regarding the quality of colonoscopy and complete polypectomy were the main reasons for nonadherence.

Intrathoracic Desmoid Tumor Presenting as Multiple Lung Nodules 13 Years after Previous Resection of Abdominal Wall Desmoid Tumor / 결핵및호흡기질환

Desmoid tumors are rare soft tissue tumors considered to have locally infiltrative features without distant metastasis until now. Although they are most commonly intraabdominal, very few cases have extra-abdominal locations. The origin of intrathoracic desmoid tumors is predominantly the chest wall with occasional involvement of pleura. True intrathoracic primary desmoid tumors with no involvement of the chest wall or pleura are extremely rare. We recently experienced a case of true intrathoracic desmoid tumor presenting as multiple lung nodules at 13 years after resection of a previous intraabdominal desmoid tumor.

Polymicrobial Purulent Pericarditis Probably caused by a Broncho-Lymph Node-Pericardial Fistula in a Patient with Tuberculous Lymphadenitis

Purulent pericarditis is a rare condition with a high mortality rate. We report a case of purulent pericarditis subsequently caused by Candida parapsilosis, Peptostreptococcus asaccharolyticus, Streptococcus anginosus, Staphylococcus aureus, Prevotella oralis, and Mycobacterium tuberculosis in a previously healthy 17-year-old boy with mediastinal tuberculous lymphadenitis. The probable route of infection was a bronchomediastinal lymph node-pericardial fistula. The patient improved with antibiotic, antifungal, and antituberculous medication in addition to pericardiectomy.

A Case of Acute Recurrent Pancreatitis Caused by Branch Duct Type IPMN and Ampulla of Vater Adenoma with High Grade Dysplasia / 대한내과학회지

Acute pancreatitis is an inflammatory disease that can extend to extra-pancreatic tissues and distant organs. Detecting the underlying cause is important because it helps provide an appropriate treatment plan and improve prognosis. An underlying cause cannot be identified after initial evaluation in 10-30% of patients with acute pancreatitis, and they are diagnosed with idiopathic acute pancreatitis. Here, we report a case of a 77-year-old woman with acute recurrent pancreatitis caused by a branch duct-type intraductal papillary mucinous neoplasm (IPMN) and an ampulla of Vater adenoma. Abdominal computed tomography and magnetic resonance cholangiopancreatography revealed only IPMN. However, endoscopic retrograde cholangiopancreatography revealed a mucosal abnormality of the ampulla of Vater. The mucosal abnormality was documented to be an ampulla of Vater adenoma with high-grade dysplasia.
