The decision of surgical treatment for pancreatic cystic lesions may mainly depend on the malignant potential of each lesion. Surgical excision is the most optimal treatment for the mucinous cystic neoplasm due to its high malignant potential. On the other hand, intraductal papillary mucinous neoplasm (IPMN) is divided into main duct type and branch-duct type. Main duct IPMN has high risk of malignant transformation. Therefore, surgical resection has been recommended for all main duct IPMN. Branch duct IPMN has relatively low malignant potential, and usually shows slow progression. A branch duct IPMN that is asymptomatic, less than 3 cm in size and without mural nodules may be followed-up without resection. Serous cystic neoplasm is usually benign in nature. Surgical treatment for serous cystic neoplasm should be considered when definitive diagnosis being uncertain, larger than 4 cm in size, or presence of symptoms. Solid pseudopapillary neoplasm also has low malignant potential which needs surgical excision. Surgical treatment for pancreatic pseudocyst is considered in limited cases with complication, such as infection or bleeding, and which is not controlled with non-surgical treatment. Management strategy for pancreatic cystic lesions should be individualized, and the decision to resect or follow-up a lesion should be based on factors such as the presence or absence of symptoms, patient age, cyst size, grading of malignant potential, location of the lesion, and the surgical risk of the patient.

Background/Aims: Glucocorticoid is mainly used for the treatment of inflammatory bowel disease (IBD). However, such a treatment occasionally shows refractory cases and a long-term use causes serious side effects. It would be very useful if we could predic

Cholethorax (bilious pleural effusion) is an extravasation of bile into the thoracic cavity via a pleurobiliary fistula (and also a bronchobiliary fistula). It is an extremely rare complication of thoraco-abdominal injuries. It can be caused by congenital anomaly and also by hepatobiliary trauma, severe infection or iatrogenic procedures. The definitive diagnosis is made with aspiration of bilious fluid from the pleural space during thoracentesis, by finding a fistulous tract during endoscopic retrograde cholangiopancreatography (ERCP) or cholagioscopy, or with finding an abnormal pleural accumulation of radioisotope during hepatobiliary nuclear imaging. Its symptoms include coughing, fever, dyspnea and pleuritc chest pain. Herein we report on a case of cholethorax following performance of percutaneous transhepatic cholangioscopy (PTCS) to remove incidentally discovered common bile duct (CBD) stones.

Pancreatic arteriovenous malformations (AVM) are extremely rare diseases frequently complicated by gastrointestinal hemorrhage. While surgical resection of affected lesion is preferred for the treatment of pancreatic AVM, angiographic intervention can be used as an alternative treatment, especially in surgically high-risk patients. We experienced a patient with pancreatic AVM manifested by hemobilia and biliary sepsis. Superior mesenteric and common hepatic arteriography showed pancreaticoduodenal AVM composed of nidus supplied by numerous fine feeding arteries and of draining veins encircling the common bile duct (CBD). Hemobilia was controlled by transportal coil embolization of draining veins of AVM around the CBD. Herein, we report this case with the review of literatures. (Korean J Gastroenterol 2007;50:265-270)

Background/Aims: Although endoscopic resection is widely used for the treatment of early colorectal cancer, the risk factors for lymph node metastasis are not clear. This study was designed to determine the risk factors for lymph node metastasis in patients with colorectal cancer who are treated by endoscopic resection. Methods: The medical records of patients with histologically-proven early colorectal cancers who were treated by endoscopic resection between January 2002 and September 2008 were retrospectively reviewed. Information regarding the demographic data of patients and the clinicopathologic characteristics were recorded and analyzed. Results: Twenty-nine patients who underwent subsequent surgical treatment after endoscopic resection for early colorectal cancer were enrolled in this study. Six patients (20.7%) had lymph node metastases on surgical pathologic examination. The predictive factors for lymph node metastasis were tumor morphology (non-polypoid flat tumors [p=0.019]), absence of background adenomas (p=0.033), and deep submucosal invasion ≥2,000 um (p=0.012). Unexpectedly, the presence of vascular invasion was not associated with lymph node metastasis. Conclusions: The presence of vascular invasion might not be an absolute indication for additional surgical treatment of early colorectal cancer; however, deep submucosal invasion, accompanied by a gross tumor with a non-polypoid flat morphology, and the absence of background adenomas are potential risk factors for lymph node metastasis.

출혈성 복수가 합병된 Henoch-Schonlein 자반증

Henoch-Schonlein purpura (HSP) is a systemic vasculitis with IgA dominant immune complex deposits affecting small vessels in the skin, joint, gastrointestinal tract, and kidneys. Gastrointestinal symptoms are common and may precede the appearance of characteristic skin rash. These manifestations include abdominal pain, bleeding, bowel infarction, intussusception, or even, perforation. However, hemorrhagic ascites has been rarely described in patients with HSP. The pathophysiologic mechanism is presumably a vasculitis of the small vessels within the serosa. We report a 37-year-old man with HSP complicated by hemorrhagic ascites. Contrast CT of the abdomen showed extensive bowel wall thickening and ascites. A paracentesis yielded hemorrhagic fluid. These abdominal manifestations were improved after methylprednisolone pulse therapy.

Duplications of the gastrointestinal tract are rare congenital malformations that are usually present during the first decade of life. However, a smaller number of cases may remain occult until adulthood. Overall, the colon is the least common site of congenital gastrointestinal duplications. Colonic duplications can present with symptoms of diverticulitis and can be confused with acquired giant cysts or masses. We present a rare case of a duplication cyst of the colon in a female adult. Although the preoperative evaluations, including an abdominal CT scan and colonoscopy, were suggestive of a gastrointestinal tumor of the colon, the final diagnosis was a colonic duplication cyst based on the histopathologic examination of the resected specimen. Even if intestinal duplication cysts are uncommon, they should be considered in the differential diagnosis of intestinal masses. (Intest Res 2009;7:64-67)

Accessory spleens are common congenital anatomic variations that are usually asymptomatic. On the other hand, they can be clinically significant if complicated by hemorrhage, torsion, or infarction. This paper describes a case of an infarcted accessory spleen in a 30-year-old male who presented with abdominal pain. Abdominal CT and MRI revealed an isolated mass, 4.5 cm in size, in the perisplenic area. An infarcted accessory spleen was suspected. The patient underwent laparoscopic accessory splenectomy. Histopathology identified the mass as splenic tissue that had undergone ischemic necrosis. A definitive diagnosis of an infarcted accessory spleen was made, and the patient was discharged on day 5 after surgery symptom-free. (Korean J Gastroenterol 2021;78:183-187)
