A Case of Chlamydia trachomatis Peritonitis Mimicking Tuberculous Peritonitis / 대한소화기학회지

Lymphocytic ascites with low serum-ascites albumin gradient (SAAG) are observed mainly in tuberculous peritonitis, peritoneal carcinomatosis, and pancreatic disease. However, pelvic inflammatory disease (PID) induced generalized peritonitis causing diffuse ascites has been rarely described. We report a 26-year old female patient, who was diagnosed as generalized peritonitis with diffuse ascites due to Chlamydia trachomatis infection. Gynecologic examination did not show the clue of PID and in the analysis of ascites, low SAAG, predominant lymphocyte count and high level of adenosine deaminase were noted. Although the best impression was tuberculous peritonitis on the base of these findings, the laparoscopic finding was consistent with PID and the PCR for C. trachomatis infection in cervical swab was positive. This case suggests that C. trachomatis peritonitis should be considered as a rare cause of low SAAG and lymphocytic ascites in sexually active women and should be intensively evaluated including laparoscopic examination.

Clinical Factors Predicting for Neoplastic Transformation of Gastric Hyperplastic Polyps / 대한소화기학회지

BACKGROUND/AIMS: Hyperplastic polyps (HPs) are the most common cause of all benign epithelial gastric polyps, constituting 30 to 93%. Although gastric HPs are usually considered as benign lesions compared with adenoma, neoplastic transformation has been known to occur rarely. We aimed to identify the clinical factors of gastric HPs predicting for neoplastic transformation. METHODS: Between January 2002 to August 2010, a total of 274 gastric HPs, which had been removed by endoscopic polypectomy or surgical resection from 210 patients, were analyzed retrospectively. RESULTS: Neoplastic transformation was found in 15 cases (5.5%) of 274 HPs including 10 cases of low grade dysplasia (3.7%), 2 cases of high grade dysplasia (0.7%) and 3 cases of adenocarcinoma (1.1%). Neoplastic transformations were significantly associated with >1 cm in size (n=10 [66.7%] vs. n=91 [35.1%], p=0.024), with pedunculated shape (n=9 [60.0%] vs. n=62 [23.9%], p=0.002), with previous history of gastrectomy (n=3 [20.0%] vs. n=3 [1.2%], p=0.002) and with synchronous neoplastic lesions occurring elsewhere in the gastric mucosa (n=5 [33.3%] vs. n=31 [12.0%], p=0.021). However, no significant difference was found between HPs with and without neoplastic transformation in terms of age, sex, number of polyps detected per patient, location, macroscopic appearance such as erosion, hyperemia. CONCLUSIONS: Neoplastic transformation of gastric HPs had significant relationships with >1 cm in size, pedunculated shape, postgastectomy state, and synchronous neoplastic lesion. Therefore, endoscopic polypectomy should be considered in these HPs to avoid the risk of missing HPs with neoplastic potential.
