  • Recently, medical accidents related to surgical procedures have increased. In addition, the media reported that some of these accidents were involved in health crimes. Patient-advocate groups have called for mandatory establishment and management of CCTV in operating rooms. There is a lot of discussion among the interested parties, so it is necessary to review the relevant laws and regulations. The purpose of this study is to identify the characteristics of CCTV in operating rooms and to review legislations related to establishment and management of the CCTV in operating rooms. Medical institutions use CCTV for management of facilities and patient safety and install it in operating rooms optionally. The Constitution guarantees the privacy and the privacy of correspondence of every citizen, but it can be limited by the law for public welfare. Currently, however, there is no existing law about establishment and management of the CCTV in operating rooms and it can be defect of legal system. Under the current legislations, it is likely that the Self-determination can be violated due to the characteristic of healthcare provider when CCTV is mandatorily installed in operating room. In addition, the regulations on access and leakage of confidential information known by operator are insufficient. So that, the safety of the visual data might be threatened. Furthermore, unless the period and the place of storage of the visual data are clearly defined, it is highly unlikely to meet the original purpose of patient safety and prevention of medical accidents. This study is meaningful as there is few previous study on this topic although the need for legal review about this is growing and several bills are being proposed. It is expected that the results of this study can be utilized as basic data for enactment or amendment of the laws and regulations about establishment and management of CCTV in operating rooms.

  • Purpose: This study was conducted to identify potential dangers involved in procedure and evaluate complications of percutaneous endoscopic gastrostomy (PEG) comparing to surgical gastrostomy (SG). Methods: A retrospective study of 66 children with feeding gastrostomy between 1994 and 2002 was done. Results: Of 66 children, 23 (mean age 29 months) had PEG and 43 (mean age 49 months) had SG. 31 cases of SG group had fundoplication for gastroesophageal reflux disease. PEG groups were followed up with an average 13 months and SG groups with 21 months. Major complications occurred in 33% of PEG group (8/23) and 55% of SG group (24/43). Major complications were significantly lower in PEG group than SG group and minor complications, too (p<0.05). Of major complications, aspiration pneumonia was the most common but paralytic ileus was significantly higher in SG group than PEG group. 8 patients died of underlying disease but not related to gastrostomy. Removals of stomata were done in 5 of PEG group and 3 of SG group. GER recurred in 25% of SG group with fundoplication and newly developed in 17% of SG group. GER persisted in 17% and newly developed in 5% of PEG group. Conclusion: The gastrostomy was a significant procedure with the potential to produce complications. PEG is recommended as an initial procedure in children requiring a feeding gastrostomy but should be considered a major undertaking.

  • Purpose: In this study, we tried to evaluate the clinical characteristics or circumstances that lead to unintentionally the delay in the diagnosis of intussusception or to the wrong direction that prevent the proper management early. Methods: All the patients of intussusception with delayed diagnosis in the department of pediatrics or emergency room at Gyeongsang National University Hospital from 1990 to 2003 were enrolled and reviewed retrospectively. Results: There were 8 boys and 6 girls and their median age was 8 months (range 2 months to 10 years). Their initial symptoms and signs were vomiting, seizure, diarrhea, lethargy, irritability, bloody stool, palpable abdominal mass, foul odor of urine and tachycardia. Clinical diagnosis or impressions at admission consisted of acute gastroenteritis, shigellosis and toxic encephalopathy, convulsive disorders, urinary tract infections, sepsis, abdominal mass and intestinal obstruction. Eight patients were luckily diagnosed due to the delayed manifestations of cyclic irritability or currant jelly stool. Six patients were not paid attentions for the possibilities of intussusception and diagnosed serendipitiously by the abdominal sonography or CT during the evaluation of the abdominal mass or distension. Only five of 14 cases (35.7%) were successfully managed by barium or air reductions. The other 9 cases needed surgical operations. Conclusion: Delayed diagnosis of intussusception arise when doctors initially diagnose the patients incorrectly due to the unusual presentations or when they overlook the newly arising symptoms or signs suggestive intussusception after the admission because they are ardently attached to the first impressions or initial clinical diagnosis.

  • Purpose: Ischemic enterocolitis (IEC) is the total or partial infarction of the intestine in the absence of occlusion of a major mesenteric blood vessel. The purpose of this study was to evaluate the clinical features of IEC in children. Methods: A clinical analysis of 6 patients with IEC who were admitted to the Department of Pediatrics at Pusan National University Hospital, between 1996 and 2005 was conducted retrospectively. Patients were diagnosed with IEC based on clinical characteristics, including radiologic, endoscopic, histopathologic, and intraoperative findings. Results: Four boys and 2 girls between the age of 6 weeks and 6 years were included in this study. Most of the patients were born at term and had a birth weight that was appropriate for their gestational age. The major symptoms of IEC observed included hematochezia or hematemesis (5 cases), vomiting, diarrhea, abdominal pain or irritability (4 cases), as well as abdominal distension and fever (3 cases). IEC occurred in thecolon in 5 cases (2 descending colon, 1 descending and sigmoid colon, 1 sigmoid colon, 1 whole colon) and the duodenal bulb and gastric antrum in 1 case each. The type of the lesions observed includedulcera, which were found in 3 cases, perforation, which was pbserved in 2 cases, necrotic patches, which were observed in 2 cases, stricture, which was observedin 1 cases, and massive membranous desquamation of the epithelium, which was observed in 1 case. Two of the patients received surgical treatment and the remaining four were treated conservatively. None of the patients died. Conclusion: The presentation of IEC varies, and the findings of this study will be helpful in managing patients with IEC.

  • Purpose: Recently, enterococcus spp. have become one of the most common nosocomial pathogens with increasing rates of multi-drug resistance. However, study on enterococcal urinary tract infections (UTIs) in children is very limited, especially community acquired UTIs. We studied the clinical characteristics of enterococcus spp. in community acquired UTIs and antibiotic resistance within our urban area. Methods: All children with first episode of community acquired UTIs due to enterococcus spp. and Echerichia coli who were admitted in Pusan National University Children's Hospital between January 2010 and January 2013 were included in our study. We retrospectively reviewed their medical records. Results: During the study period, 201 patients were identified to have first episode of community acquired UTIs. 154 cases were E.coli UTIs (76.6%) and 11 cases were enterococcal UTIs (5.5%) and all enterococcus spp. were Enterococcus feacalis. In enterococcal UTI group, voiding cystourethrogram(VCUG) was performed in 7/11 patients and demonstrated 4 vesicoureteral refluxes (VURs) with renal scar and 3 patients underwent corrective surgery. In E.coli UTI group, VCUG was performed in 121/154 patients and demonstrated 23 VURs and 11 patients underwent corrective surgery. Enterococcal group had significant high rate of underlying urinary abnormalities and surgical corrections compared with E. coli group. All enterococcus spp. were susceptible to ampicillin, vancomycin and linezolid, but all were resistant to tetracycline. They also showed 71.4% resistance to trimethoprim-sulfamethoxazole and 20% resistance to ciprofloxacin. Conclusion: Community acquired enterococcal UTIs in children were rare within our urban area. However, they could be indicative of severe underlying urinary tract abnormalities.

  • Purpose: This prospective study was performed to evaluate the usefulness of preoperative radioimmunoscintigraphy and intraoperative scintimetric examination (radioimmunoguided surgery: RIGS) using $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment. Materials and Methods: Nineteen patients with rectal cancer underwent preoperative whole body planar scintigraphy at 4 hours after injection of $^{99m}Tc-anti-CEA\;F(ab')_2$ fragment and SPECT imaging at 18 hours. Surgical operation was performed at 24 hours after injection. During laparotomy, radioactivities from intraabdominal viscera were measured by gamma probe. The radioactivities from excised tumor and lymph nodes were also measured and compared with pathology. Results: All nineteen patients were confirmed to have adenocarcinomas in the rectum. Twenty-seven of 97 excised lymph node groups had metastasis and 2 patients had liver metastasis in pathology Preoperative radioimmunoscintigraphy detected primary tumors in 11 patients (sensitivity 55%) and it could not detect any lymph nodes or liver metastasis. All patients showed high radioactivity in the kidneys, liver, spleen, and major vessels in intraoperative measurement by gamma probe, and tumor activity was not discriminated from background activity However, radioactivity from excised tumor was higher than normal rectum (T/B ratio; $3.47{\pm}2.25$). When excised lymph node activity/background activity ratio >1.5 was considered as positive criteria of metastasis, sensitivity, specificity, positive and negative predictive values were 78.6%, 73.9%, 55.0% and 89.5%, respectively. Conclusion: Radioimmunoscintigraphy using $^{99m}Tc-anti-CEA\;F(ab')_2$ has no additional value for preoperative staging and use of early RIGS using $^{99m}Tc-anti-CEA\;F(ab')_2$ is inappropriate. For early RIGS using $^{99m}Tc$ labeled antibodies in rectal cancer patients, further development of more specific antibodies and methods to reduce background activity are needed.

  • Purpose: Early detection of recurrence is an important factor for long term survival of patients with colorectal cancer. Measurement of serum levels of CEA, CA 19-9, CT and PET/CT has been commonly used in the postoperative surveillance of colorectal cancer. The purpose of this study was to compare the diagnostic ability of PET/CT, tumor marker and CT for recurrence in colorectal cancer patients after treatment. Materials and Methods: F-18 FDG PET/CT imaging was performed in 189 colorectal cancer patients who underwent curative surgical resection and/or chemotherapy. Measurement of serum levels of CEA, CA 19-9 and CT imaging were performed within 2 months of PET/CT examination. Final diagnosis of recurrence was made by biopsy, radiologic studies or clinical follow-up for 6 months after each study. Results: Overall sensitivity, specificity of PET/CT was 94.7%, 91.1%, while those of serum CEA were 44.7% and 97.3%, respectively. Sensitivity and specificity were 94.2%, 90.4% for PET/CT and better than those of combined CEA and CA 19-9 measurement(52.1%, 88.5%) in 174 patients measured available both CEA and CA 19-9 data. In 115 patients with both tumor markers and CT images available, PET/CT showed similar sensitivity but higher specificity(92.9%, 91.3%) compared to combination of tumor markers and CT images(92.9%, 74.1%). Conclusion: PET/CT was superior for detection of recurred colorectal cancer patients compared with both CEA, CA 19-9, and even with combination of both tumor markers and CT. Therefore PET/CT could be used as a routine surveillance examination to detect recurrence or metastasis of colorectal cancer.

  • Purpose : The detection of hydronephrosis(HN) with antenatal ultrasonography was first reported in the 1970s. Prenatal HN is diagnosed with an incidence of 1:100 to 1:500 on antenatal screening. Recently, the purpose of antenatal screening has changed from simple detection to selection for specific diagnosis-based management. this study is to evaluate the usefulness of antenatal sonography for HN and to investigate the differential causes of HN and their clinical outcomes. Patients and methods : 11,783 live neonates with prenatal ultrasonographic examination at Ajou University School of Medicine, from Sep. 1994 to Aug. 2001 were analyzed. Results and conclusion : Hydronephrosis (>10 mm) was detected in 119 (1.0%) cases antenatally and among these, 91 were proved to have HN postnatally Males were three times more affected than females. Additional imaging studies revealed that ureteropelvic junction obstruction was the most common postnatal diagnosis (47%), followed by multicystic dysplastic kidney, vesicoureteral junction obstruction and vesicoureteral reflux. During 20 months' follow-up(3 to 72 months), 58(48%) renal units showed spontaneous resolution and surgical interventions were necessary in 10 (7.4%) of postnatally confirmed hydronephrotic renal units.

  • Purpose : Vesicoureteral reflux (VUR), which can result in renal failure in children, is expected to resolve spontaneously in mild cases, but severe cases require surgical correction, posing dilemma in deciding the right measures in some cases. Therefore, to delineate the factors affecting spontaneous resolution of VUR and to apply them in assessing the prognosis, we reviewed the patients with VUR who had been treated medically. Patients and Methods : 32 children (49 renal units) with reflux who had been admitted during the 5-year period from Jan '92 to Dec '96 were classified into 4 groups (Resolved, Improved, Unchanged, and Worsened) and analyzed. Results : 1) 25 were boys and 7 girls. The age at diagnosis ranged from 13 days to 9 years (mean $24.6{\pm}11.4$ mo) 2) Among 49 refluxing ureters, 4 were below 1 me of age,21 between 1 me to 1 yr, 16 between 1 yr to 6 yr, 8 beyond 6 yr. Two belonged to Grade I, 16 to Crade II, 17 to Grade III, 12 to Grade IV, and 2 to Grade V. 3) Spontaneous resolution rates of reflux were 100, 81, 47, 8, 0$\%$ for each Grade, respectively. Resolution plus improvement rates in Grade III and IV were 71 and $50\%$, each. 4) Resolution rates in relation to the age at diagnosis were $100\%$ for below 1 mo, $48\%$ between 1 mo to 1 yr, $56\%$ between 1 to 6 yr, and $13\%$ beyond 6 yr. 5) Of 15 unilateral refluxing ureters, 14 ($93\%$) resulted in resolution. Of 34 bilateral refluxing ureters, 11 ($32\%$) resolved spontaneously 6) Resolution occurred within 1 year in 20 units of 24 renal units in regular follow-up. Conclusion: The lower the initial grade and the younger the patient, the sooner the reflux resolved. Resolution was better when VUR was unilateral than bilateral. Long-term regular follow-up is essential because even the cases falling in Grades III and IV have high rates of spontaneous resolution and improvement with medical treatment.

  • Purpose : To analyze the clinical characteristics, spontaneous resolution rate and predictive factors of resolution in children with primary vesicoureteral reflux(VUR). Methods : Between October 1991 and July 2003, 149 children diagnosed with primary VUR at Chonbuk National University Hospital were reviewed retrospectively. All of the patients were maintained on low-dose antibiotic prophylaxis and underwent radionuclide cystograms at 1 year intervals over 3 years after the initial diagnosis of VUR by voiding cystourethrogram was made. Results : The median time to resolution of VUR was 24 months and the total 3 year-cumulative resolution rate of VUR was 61.7%. The following variables were associated with resolution of VUR according to univariate analysis-; age<1 year, male gender, mild grade of reflux, unilateral reflux, congenital hydronephrosis as clinical presentation at time of diagnosis of VUR, absence of focal defects in the renal scan at diagnosis, absence of recurrent UTI, renal scars and small kidney during follow-up. After adjustment by Cox regression model, five variables remained as independent predictors of VUR resolution; age<1 yew, relative risk 1.77(P<0.05), VUR grade I+II 2.98(P<0.05), absence of renal scars 2.23(P<0.05), and absence of small kidney 5.20(P<0.01) during follow-up. Conclusion : In this study, spontaneous resolution rate of VUR, even high grade reflux, is high in infants during medical management, and it was related to age, reflux grade at diagnosis, absence of renal scars and small kidney during follow-up. Therefore early surgical intervention should be avoided and reserved for the selected groups.
