ABSTRACT

BACKGROUND: The aim of this study was to investigate the feasibility and safety of endoscopic resection of gastric neoplasm in solid-organ transplant (SOT) recipients. METHODS: Between January 1994 and December 2011, the results of endoscopic resection of 17 lesions in 15 consecutive patients who had previously undergone SOT at Asan Medical Center were retrospectively evaluated. We compared clinical outcomes of this group with 1:5 matched non-SOT patients treated by endoscopic resection. RESULTS: Of the 6,491 patients who underwent SOT during the study periods, 30 patients (0.46%) with 31 lesions were diagnosed with gastric cancer, and eight patients (0.12%) with nine lesions were diagnosed with gastric adenoma. Among them, 15 patients with 17 lesions were treated by endoscopic resection, and 19 patients with 20 lesions have undergone gastrectomy. In endoscopically resected SOT group, the median duration between transplantation and endoscopic treatment was 41 months (range, 5-196 months). En bloc and complete resection were achieved in 13 (76.5%) and 15 (88.2%) lesions. Four lesions (23.5%) experienced bleeding, which was successfully managed endoscopically. When compared with post-endoscopic resection bleeding rate of non-SOT group (5.9%, [5/85]), there was no significant difference in multivariable analysis (P=0.083). CONCLUSIONS: In endoscopic resection for gastric neoplasm of SOT recipients, only manageable complications were noted in some patients, and graft dysfunctions or perforations did not occur. To avoid surgical resection with its associated perioperative mortality and morbidity, endoscopic resection for gastric neoplasm in SOT recipients is recommended as a feasible treatment with high efficacy and safety.

ABSTRACT

BACKGROUND/AIMS: Infection of pancreatic necrosis is one of the leading cause of death in patients with severe necrotizing pancreatits. Because of high mortality rate up to 50%, immediate surgical debridement including pancreatectomy is recommended. However, early surgical treatment still showed high mortality rate and better treatment strategy is required. This study was conducted to evaluate the outcomes of early intensive non-surgical treatments in patients with infected necrotizing pancreatitis. METHODS: This study was based on retrospective analysis of 71 patients with acute severe necrotizing pancreatitis (APACHE II score>or=8, or Ranson's score>or=3, and pancreatic necrosis on CT scan), who were admitted to medical center during past 16 years. Infection of pancreatic necrosis was confirmed by fine needle aspiration, and early intensive medical treatments comprised of prophylactic antibiotics coverage, fluid resuscitation, organ preserving supportive measures, and percutaneous catheter drainage were carried out. RESULTS: Among the enrolled patients, infections were suspected in 46 patients, but fine needle aspirations were done only in 32 patients. In 21 patients, infections of necrotic tissue were confirmed by bacteriology, while other 11 patients showed no evidence of bacterial growth. Of 21 patients with infected necrosis, initial surgical interventions were performed in 2 patients, while initial medical treatments were performed in 19 patients. The success rate of medical treatment group in infected necrotizing pancreatitis was 79% (15/19). The mortality rate of medical treatment group and surgical treatment group was 5% (1/19) and 50% (1/2). CONCLUSIONS: Early intensive medical treatment seems to be a good therapeutic strategy, even if the infection has developed in pancreatic necrosis. Further prospective randomized studies are required to confirm this finding.

ABSTRACT

BACKGROUND/AIMS: The involvement of bile ducts is frequently reported in autoimmune pancreatitis (AIP), which seem to have similar features to primary sclerosing cholangitis (PSC). Recent systematic comparative studies about these diseases are rare in Korea. METHODS: We retrospectively analyzed 26 patients with AIP with bile duct involvement and 30 patients with classic PSC who were diagnosed during the last decade. RESULTS: The mean age of patients was significantly higher in AIP than PSC at the time of diagnosis. There was a preponderance of men in both group, which was more prominent in AIP. The most common symptom in patients with AIP was jaundice, but PSC patients usually visited hospitals due to incidentally detected abnormal liver function tests. Most (26/31) of AIP had bile duct involvement. All of these patients showed narrowing of intrapancreatic common bile ducts and one patient exhibited hilar involvement as well. About 80% of PSC had both intra- and extrahepatic ducts involvement, and the characteristic features involve multifocal strictures. AIP patients showed improvement with steroid treatment, however, most PSC patients showed clinical deterioration. CONCLUSIONS: The clinical and cholangiographic findings of patients with AIP and PSC have many different characteristics. Therefore, further study of two diseases is required for the proper diagnosis and management.

ABSTRACT

BACKGROUND/AIMS: Biliary cystadenoma (BCA) and biliary cystadenocarcinoma (BCACa) are rare cystic neoplasms that usually arise from the liver. We reviewed the clinicopathologic and radiologic findings of 13 cases of intrahepatic biliary cystic neoplasms. METHODS: Seven patients with BCA and 6 patients with BCACa which were pathologically proven within past 10 years were included in this retrospective study. RESULTS: BCA (7 of 7) was more common in female compared to BCACa (4 of 6). Mean age at diagnosis was 53.4 years (BCA) and 58.5 years (BCACa). Abdominal pain (54%) was the most common presenting symptom. Eleven patients (61.5%) exhibited normal liver function profiles and 5 patients (38%) showed elevated levels of serum CA19-9 levels (mean 894.2 U/mL, range: 78.7-2,080). Mean size of tumor was 11.7 cm (range: 5-15). Most frequent radiologic finding was a single cystic mass with septation. BCACa tended to have intracystic solid portion. The cut surface revealed a unilocular or multilocular cystic mass with mucinous contents. Complete surgical excision was done in 12 patients. After the complete resection, recurrence was observed in 1 case of BCACa. CONCLUSIONS: The possibility of biliary cystic neoplasm should be suspected when an intrahepatic cystic lesion with multiseptation or solid portion is noted on imaging study. In addition, complete excision for definite diagnosis and treatment need to be performed.
