Background: This report presents annual data from the surgical site infection (SSI) module of the Korean National Healthcare-associated Infections Surveillance System (KONIS) from July 2021 to June 2022. Methods: Surveillance of 20 surgeries (e.g., stomach, colon, rectal, gallbladder surgery, knee replacement, hip replacement, craniotomy, ventricular shunts, spinal fusion, laminectomy, cardiac artery bypass grafting - incision in the chest site only and incisions both the chest and donor site, cardiac, prostatectomy, abdominal hysterectomy, vaginal hysterectomy, appendectomy, thoracic, cesarean section, and head and neck surgeries) associated with SSI was performed between July 1, 2021, and June 30, 2022, according to the KONIS Manual 2020. Results: A total of 133,281 surgical cases were collected and 1,100 SSIs were identified, resulting in a SSI rate of 0.83%. The SSI rates for 30-day surveillance surgeries were 1.9% for stomach, 2.82% for colon, 1.88% for rectal, 0.29% for gallbladder, 0.25% for lumbar laminectomy, 0.33% for cesarean section, 0.67% for abdominal hysterectomy, 0.74% for vaginal hysterectomy, 0.23% for prostatectomy, 1.39% for appendectomy, and 0.06% for thoracic surgeries. Neck surgery could not be analyzed due to no reported cases. The SSI rates for the 90-day surveillance surgeries were 0.16% for knee replacement, 0.54% for hip replacement, 0.89% for spinal fusion, 0.70% for craniotomy, 0.92% for ventricular shunt, 1.13% for cardiac, 1.80% for cardiac artery bypass grafting (chest only incision), and 1.64% for cardiac artery bypass grafting (chest and leg incision) surgeries. In total, 608 strains were isolated and cultured from 1,286 infections. Conclusion Compared with the incidence of SSI (1.06%) in 2018, the overall incidence decreased, and most site-specific infection rates decreased or remained the same.

BACKGROUND: Cystic neoplasms of the pancreas are being recognized with increased frequency. In 1993, a report on 123 cases of cystic neoplasms of the pancreas diagnosed over a period of 32 years was published in Korea. Many changes on the concept of cystic neoplasms of the pancreas have been made, including classification and diagnostic criteria. The present study was conducted wherein a new survey on cystic neoplasms of the pancreas in Korea. METHODS: Cystic neoplasms of the pancreas diagnosed over a period of 12 years, from 1993 to 2004 in 25 university hospitals throughout Korea were collected. They were classified according to the World Health Organization classification of cystic neoplasms of the pancreas. RESULTS: A total of 1264 cases of cystic neoplasms of the pancreas were diagnosed. The diagnoses and frequencies are as follows: intraductal papillary mucinous neoplasm, 499 (39.5%); mucinous cystic neoplasm, 318 (25.2%); serous cystic neoplasm, 232 (18.4%); solid pseudopapillary neoplasm, 192 (15.2%); cystic endocrine neoplasm, 11 (0.8%); lymphoepithelial cyst, 8 (0.6%); acinar cell neoplasm, 3 (0.2%); mature teratoma, 1 (0.1%). Increase in the annual number of diagnoses was evident. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, a significant increase in mean age was seen in patients with malignant neoplasms. CONCLUSIONS: Cystic neoplasms of the pancreas are diagnosed with increasing frequency in Korea, the most common being intraductal papillary mucinous neoplasm of the pancreas. In intraductal papillary mucinous neoplasm and mucinous cystic neoplasm, the grade of dysplasia increased with mean age, suggesting an adenoma-carcinoma sequence.

Anisakiasis is a disease of the alimentary tract caused by nematode larva belonging to the subfamily Anisakinae. It is possible for Anisakis larva to be transmitted to man through eating raw sea fish that is preferred by Korean people. The clinical symptoms are characterized by severe cramping abdominal pain, nausea, vomiting, diarrhea, tarry stool, and epigastric fullness. The endoscopic examination has played a important role in the diagnosis of anisakiasis. However, gastric anisakiasis is undetected due to unspecific symptom and delayed endoscopy. Endoscopic ultrasonography is probably the choice of investigative tool for the evaluation of submucosal mass. However distinctive feature of parasitic infectation presenting an submucosal tumor has not been reported. Recently, we experienced two cases of gastric anisakiasis. We found gastric submucosal tumors by endoscopy, differentiated them by endoscopic ultrasonography and treated by endoscopic submucosal resection.

Fibrinolytic properties have been detected in animal and human gallbladder (GB) bile. Plasminogen activator inhibitor-1 (PAI-1) has been reported in greater concentration in GB stone bile and may be a nucleating factor in the pathogenesis of GB stone formation. It is unknown whether or not human choledochal bile has similar properties, which could have a role in choledocholithiasis. The aims of this study were to determine the presence of fibrinolytic properties of human choledochal bile and to compare those properties among normal, acalculous, and calculous-infected choledochal bile. Tissue plasminogen activator (t-PA) and PAI-1 of choledochal bile were measured by enzyme linked immunosorbent assay in patients with cholangitis due to acalculous bile duct obstructions (n = 9), choledocholithiasis with cholangitis (n = 20), and normal bile (n = 7). The t-PA concentration of choledochal bile was no different among the three groups (acalculous-infected bile, median 4.61 ng/ml, and calculous-infected bile, 4.61 ng/ml, versus normal bile, 7.33 ng/ml). PAI-1 was detected in choledochal bile in significantly greater concentrations in patients with acalculous cholangitis due to bile duct obstructions and choledocholithiasis with cholangitis (acalculous-infected bile, median 0.36 ng/ml, and calculous-infected bile, 0.1 ng/ml, versus normal bile, 0.02 ng/ml, p < 0.05), but the bile concentration of PAI-1 was no different between the acalculous and calculous-infected choledochal bile. Human choledochal bile possesses t-PA and PAI-1. PAI-1 was present in greater concentrations in both acalculous and calculous-infected choledochal bile. Increased levels of PAI-1 may be an epiphenomenon of cholangitis rather than a factor in the pathogenesis of choledocholithiasis.

PURPOSE: To evaluate postcontrast CT findings of acute pyelonephritis and correlate these with clinical findings and severities. MATERIALS AND METHODS: We retrospectively reviewed the medical records and CT scans of 50 patients with abnormal CT findings among 52 patients of acute pyelonephritis whose postcontrast CT scans had been examined. Fifty cases of acute pyelonephritis were classified into three subgroups on the basis of postcontrast CT findings : Group I (n=20, 40%) wedge-shaped lesions; Group II (n=13, 26%) mass-like lesions; Group III (n=17, 34%) renal abscess formation. In each group, clinical findings and severity were analyzed and correlated with CT findings. The results were statistically analyzed. RESULTS: Although mean values of clinical parameters of group I were lower than those of group II and III with regard to all clinical parameters (including maximal temperature and duration of fever, flank pain, leukocytosis, and admission period), there was no statistically significant correlation among the three groups (p>0.05). All cases were successfully treated with antibiotics only, despite the high rate of abscess formation (34%). CONCLUSION: Acute pyelonephritis spans a continuum of CT findings of varying severity from wedge-shaped or mass-like lesions to multifocal abscesses ; postenhanced CT scan shows high sensitivity (96%) in the detection of acute pyelonephritis. Although the clinical course of groups of mass-like lesions and abscess formation was longer and more severe than that of wedge-shaped lesions, there was no statistically significant clinicoradiologic correlation among the three groups.

BACKGROUND: Knowledge about the degree of risk and location of multiple primary cancers can facilitate the targeting of screening and surveillance practices on follow-up after treatment of cervical cancer. PURPOSE: The retrospective study was performed to evaluate the characteristics of multiple primary malignancies in patients treated for cervical carcinoma. METHOD: From data base file of gynecologic cancer patients between 1976 and 1995, total 20 patients were found to have cervical cancer and another primary malignancy. Their medical records and pathologic slides were reviewed. Follow-up information was obtained from medical records or by telephone. RESULT: There were 8 synchronous and 12 metachronous multiple primary cancers (MPC) among 20 patients. Their mean age was 51 years (range 23 ~ 68 years). The distribution of FIGO stage of the patients with cervical cancer was classified into stage I, 6 patients; stage II, 9 ; and stage III, 5. All patients showed squamous cell type histology of cervical cancer. Eight(40 %) of 20 patients developed second cancer in uterus : 6 malignant mixed Mllerian tumors(MMMT), one endometrial stromal sarcoma, and one endometrial adenocarcinoma. Seven of 8 synchronous type MPC patients are alive (median follow-up, 27 months). In contrast, only one out of 12 metachronous type MPC patients is alive(median follow-up, 114 months). The occurrence of eight malignancies including 6 MMMT, one bladder cancer, and one rectal cancer might be related with previous radiation therapy for cervical cancer. CONCLUSION: These results suggest that routine screening and surveillance work-up might not be necessary in most of patients with cervical cancer. However, the patients with cervical cancer undergoing radiation treatment have to be followed carefully with the consideration of possibility for developing second cancer in the field of irradiation.

We report the case of a 44-year-old woman underwent cholecystectomy with two common bile duct stones (2.6 x 1,9 cm and 1.6 X 1.0 cm) which failed to be captured by endoscopic mechanical lithotriptor. However, those were successfully dia-integrated with extracorporeal shock wave lithotripsy (ESWL), permitting subsequent endosaopic extraction using the Dormia basket of the fragments without complication; In our experience, ESWL is considered to be a new and safe method to treat patients with common bile duct stone which cannot be removed by endoscopic mechanical lithotripsy.

A case of congenital orbital teratoma with marked unilateral proptosis was noted at birth, Patients with congenital orbital teratoma had a uniform clinical picture and were very similar in their morphological pattern, often polycystic and with varied amounts of solid tissue. Six months after birth, the orbital tissues were totally extirpated. Histological examination revealed components from all three germinal layers and no sign of malignancy. Within the first year, the condition of the patient has been satisfactory.
