Spontaneous perforation of the bile duct in children is a very rare disorder. We experienced a 6 year-old girl with spontaneous perforation of the right hepatic duct. The patient was initially misdiagnosed as hepatitis because of elevation of liver enzyme and then as appendicitis because of fluid collection in the pelvic cavity demonstrated by ultrasonogram. A laparoscopic exploration was done and no abnormal findings were detected except bile-stained ascites. Peritoneal drainage was performed and the patients seemed to improve clinically. Abdominal pain, distention and high fever developed after removal of the drains. DISIDA scan showed a possible of bile leak into the peritoneal cavity. ERCP demonstrated free spill of dye from the right hepatic duct. At laparotomy, the leak was seen in the anterior wall of the right hepatic duct 2cm above the junction of the cystic duct and common hepatic duct. The perforation was linear in shape and 0.8cm in size. The patient underwent cholecystectomy, primary closure of the perforation and T-tube choedochostomy. We could not identify the cause of the perforation; however, the T-tube cholangiography taken on the 42nd postoperative day showed a little more dilatation of the proximal common bile duct compared with the cholangiography taken on the 14th day. Long-term follow-up of the patient will be necessary because of the possibility for further change of the duct.

The medicinal herb Oldenlandia diffusa is known as a folk medicine for the treatment of hepatitis, sore throat, appendicitis, malignant tumors and urethral infection in Southern China and Korea. Another species O. corymbosa, is also used for the therapy of the similar conditions, however, only O. diffusa is referred to the medicinal herb by Chinese Pharmacopoeia. Due to their similar morphology, O. diffusa and O. corymbosa are often misidentified. To easily identify O. diffusa from O. corymbosa, the phylogenetic utility of nuclear ribosomal DNA (nrDNA) internal transcribed spacers (ITS) were investigated among different O. diffusa and O. corymbosa populations in Korea. The nrDNA ITS sequence of O. diffusa contained 791 bp, with GenBank accession number of JF837601-JF837602. The nrDNA ITS sequence of O. corymbosa was 785-786 bp, with GenBank accession number of JF837603-JF837611. The results showed that there are some certain divergences in the ITS region sequence between both species, even among different populations of the same species. Particularly, O. corymbosa ST-4 population showed the highest dissimilarity of the ITS region sequence with other nine populations of O. corymbosa and two populations of O. diffusa. This consequence makes us further understand the molecular diversification between O. corymbosa and O. diffusa, and help to promote the correct use and safety.

A human case infected with Terranova type A larva was found in Korea. The patient was a 23-year old soldier of the Korean Army and the chief complaint was acute abdominal pain. The pain was chiefly at right lower quadrant. Appendectomy was performed under the clinical impression of acute appendicitis. However, during the surgery, a nematode larva was found moving on the serosal surface of terminal ileum. The worm was 25.76mm long and O. 66mm -wide, and had the intestinal cecum reaching to anterior one-third level of ventriculus and a mucron at posterior end. Therefore, it was diagnosed as Terranova type A larva. This is the first human case of Terranova type A larva infection in Korea.

A large number of streptococci that do not fit readily into any of the established classification schemes have been relegated to a large heterogeneous group called the Streptococcus viridans, which are members of the normal flora of the mucous membranes of the body, including the oral cavity, the nasopharynx, and genitourinary tract. This group includes S. mitis, S. oralis, S. sanguis, S. salivarius, S. milleri, etc. Surveying on the literature, it has been reported that infective endocarditis, meningitis, rhabdomyolysis, cholangitis, appendicitis caused by Streptococcus viridans, which were the most important pathogen in children with malignant hematologic disease. Various antibiotics has been chosen for treatment or prophylaxis for these infections, but were generally lower antimicrobial susceptibilities because of an abuse of antibiotics and advent of resistant group. Therefore, surveillant culture must be performed to evaluate personal antimicrobial susceptibilities of intraoral microbes for proper antimicrobial choice for dental procedures. This study examined sampling from subgingival plaque of 60 chidren's microbes. The cultured bacterial isolates, Streptococcus viridans were examined 10 antimicrobial drugs with the Kirby-Bauer agar disk diffusion method. The used drugs were Penicillin, Ampicillin, Oxacillin, Cephalothin, Imipenem, Gentamicin, Erythromycin, Vancomycin, Ciprofloxacin, Clindamycin. The results were as follows : 1. Sampling Streptococcus viridans were S. mitis(65%), S. oralis(22%), S. sanguis(5%), S. intermedius(3%), S. salivarius(2%), S acidominimus(2%), Unidentified streptococcus(2%). 2. The antimicrobial susceptibility of total Streptococcus viridans : Oxacillin< Erythromycin< Pencillin=Ciprofloxacin< Cephalothin< Ampicillin< Clindamycin< Gentamicin< Imipenem=Vancomycin. 3. The antimicrobial susceptibility of S. mitis : Oxacillin=Erythromycin< Ciprofloxacin< Cephalothin< Penicillin=Ampicillin< Gentamicin< Clidamycin< Imipenem=Vancomycin. 4. The antimicrobial susceptibility of S. oralis : Oxacillin< Erythromycin< Penicillin=Ciprofloxacin=Clindamycin< Cephalothin=Gentamicin< Ampicillin< Imipenem=Vancomycin. 5. There was no significant difference in the antimicrobial susceptibility among each Streptococcus viridans group.

Rectus sheath hematoma (RSH) is a rare condition caused by hemorrhage into the rectus sheath. It is usually associated with severe cough, abdominal surgery, coagulopathy, and anticoagulation treatment. RSH can be difficult to diagnose and can be misdiagnosed as acute appendicitis, as diverticulitis, or as an ovarian mass. Although RSH usually presents as a benign condition, it can be life threatening, especially in the critically-ill patient. Here, we report a case of fatal RSH due to hypovolemic shock in a critically-ill 73-year-old woman, who had received heparin treatment due to acute myocardial infarction in the intensive care unit and who had been successfully treated by conservative management.

Purpose: Thrombosis of the portal vein, known as pylephlebitis, is a rare and fatal complication caused by intraperitoneal infections. The disease progression of superior mesenteric venous thrombosis (SMVT) is not severe. This study aimed to determine the clinical features, etiology, and prognosis of SMVT. Materials and Methods: We retrospectively reviewed the medical records of 41 patients with SMVT from March 2000 to February 2017. We obtained a list of 305 patients through the International Classification of Disease-9 code system and selected 41 patients with SMVT with computed tomography. Data from the medical records included patient demographics, comorbidities, review of system, laboratory results, clinical courses, and treatment modalities. Results: The causes of SMVT were found to be intraperitoneal inflammation in 27 patients (65.9%), malignancy in 7 patients (17.1%), and unknown in 7 patients (17.1%). Among the patients with intraperitoneal inflammation, 14 presented with appendicitis (51.9%), 7 with diverticulitis (25.9%), and 2 with ileus (7.4%). When comparing patients with and without small bowel resection, the differences in symptom duration, bowel enhancement and blood culture were significant (P=0.010, P=0.039, and P=0.028, respectively). Conclusion: SMVT, caused by intraperitoneal inflammation, unlike portal vein thrombosis including pylephlebitis, shows mild prognosis. In addition, rapid symptom progression and positive blood culture can be the prognostic factors related to extensive bowel resection. Use of appropriate antibiotics and understanding of disease progression can help improve the outcomes of patients with SMVT.

Purpose: Conduct a systematic review of case reports and case series regarding the development of acute abdomen following coronavirus disease 2019 (COVID-19) vaccination, to describe the possible association and the clinical and demographic characteristics in detail. Materials and Methods: This study included case report studies and case series that focused on the development of acute abdomen following COVID-19 vaccination. Systematic review studies, literature, letters to the editor, brief comments, and so forth were excluded. PubMed, Scopus, EMBASE, and Web of Science databases were searched until June 15, 2023. The Joanna Briggs Institute tool was used to assess the risk of bias and the quality of the study. Descriptive data were presented as frequency, median, mean, and standard deviation. Results: Seventeen clinical case studies were identified, evaluating 17 patients with acute abdomen associated with COVID-19 vaccination, which included acute appendicitis (n=3), acute pancreatitis (n=9), diverticulitis (n=1), cholecystitis (n=2), and colitis (n=2). The COVID-19 vaccine most commonly linked to acute abdomen was Pfizer-BioNTech (messenger RNA), accounting for 64.71% of cases. Acute abdomen predominantly occurred after the first vaccine dose (52.94%). All patients responded objectively to medical (88.34%) and surgical (11.76%) treatment and were discharged within a few weeks. No cases of death were reported. Conclusion: Acute abdomen is a rare complication of great interest in the medical and surgical practice of COVID-19 vaccination. Our study is based on a small sample of patients; therefore, it is recommended to conduct future observational studies to fully elucidate the underlying mechanisms of this association.

Minimal invasive surgery (MIS) has rapidly gained acceptance for the management of a wide variety of pediatric diseases. A questionnaire was sent to all members of the Korean Association of Pediatric Surgeons. Thirty one members (25.4%) took part in the survey that included data for the year 2012: demographic details, opinion regarding minimal invasive surgery and robotic surgery, spectrum of minimally invasive operations, and quantity of procedures. 48.4% of the respondents had more than 10 years experience, 35.5% less than 10 years experience, and 16.1 % had no experience. The respondents of the recommend MIS and perform MIS for surgical procedures are as follow; inguinal hernia (61.3%), simple appendicitis (87.1%), complicated appendicitis (80.6%), reduction of intussusceptions (83.9%), pyloromyotomy (90.3%), fundoplication (96.8%), biopsy and corrective surgery of Hirschsprung's disease (93.5%/90.3%), imperforate anus (77.4%), congenital diaphragmatic hernia (80.6%), and esophageal atresia (74.2%). The MIS procedures with more than 70% were lung resection (100%), cholecystectomy (100%), appendectomy (96.2%), ovarian torsion (86.7%), fundoplication (86.8%), hiatal hernia repair (82.6%), and splenectomy (71.4%). The MIS procedures with less than 30% were congenial diaphragmatic hernia reapir (29.6%), esophageal atresia (26.2%), correction of malroatation (24.4%), inguinal hernia repair (11.4%), anorectal malformation (6.8%), Kasai operation (3.6%).

Purpose: Infectious ileocecitis is an infection confined to the ileocecal area and one of the most common causes of pediatric abdominal pain. This study was performed to demonstrate the clinical features of infectious ileocecitis in children. Methods: The medical records and radiologic findings of 37 patients with ileocecitis diagnosed by ultrasonography and/or computed tomography, who were admitted to Pusan National University Hospital from January 2004 and July 2008, were reviewed retrospectively. Viral gastroenteritis and secondary ileocecitis were excluded. Results: The mean age of the patients was 4.8${\pm}$3.4 years. One-half of the patients were preschool children. The chief complaint was abdominal pain (75.7%), diarrhea (10.8%), and vomiting (8.1%). Accompanying symptoms were fever (56.8%), vomiting (21.6%), and diarrhea (16.2%). The mean duration of abdominal pain, fever, diarrhea, and vomiting was 3.8${\pm}$2.1, 3.0${\pm}$1.9, 3.4${\pm}$1.9, and 2.4${\pm}$2.3 days, respectively. The frequency of diarrhea and vomiting was 5.8${\pm}$2.2 and 4.0${\pm}$2.8 per day, respectively. Diagnosis was made by abdominal ultrasonography in 22 patients (59.5%), abdominal CT in 2 patients (5.4%), and both modalities in 13 patients (35.1%). Besides the radiologic finding of thickening of the bowel wall, mesenteric lymphadenitis (59.5%), ascites (5.4%), and both mesenteric lymphadenitis and ascites (16.2%) were revealed. The mean duration of illness was 7.5${\pm}$5.0 days. There were no specific laboratory findings, and culture studies with stool or blood were negative. All of the patients recovered completely without specific treatment. Conclusion: Infectious ileocecitis has acute appendicitis-mimicking symptoms, but is self-limited within a few days, thus unnecessary treatment and work-up is avoided. However, distinguishing infectious ileocecitis from appendicitis, inflammatory bowel disease, and mesenteric lymphadenitis is important.

Purpose: Acute febrile illness in children frequently accompanies with abdominal symptoms such as vomiting, diarrhea, and abdominal pain, even if its etiology is not occured from the gastrointestinal tract. If the etiology of fever was unknown and the fever was accompanied with abdominal symptoms, we should be concerned about whether the etiology of fever was originated from the gastrointestinal tract or interpretated from the abnormality in the gastrointestinal tract. This study was performed to evaluate the diagnostic value of abdominal ultrasonography in patients with fever and abdominal symptoms. Methods: We reviewed retrospectively the medical records of abdominal ultrasonographic (US) findings of 60 cases of acute febrile illness with abdominal symptoms at department of Pediatrics, Ulsan Dongang General Hospital during the period from January 1994 to June 1995. Results: The abnormal abdominal US findings obtained were as follows. 1) The abnormal US findings were seen in 56 cases (93.3%). 2) The most common abnormal US finding was the enlarged mesenteric lymph nodes in 52 cases (86.7%) 3) The enlarged mesenteric lymph nodes with or without intra-abdominal fluid were seen in 30 cases (50.0%) of a wide variety of illnesses, so their diagnostic values were absent. 4) The enlarged mesenteric lymph nodes and splenomegaly with or without ileocecitis were seen in 7 cases. Among them, 4 cases (6.7%) were confirmed as typhoid fever. 5) The US findings in 6 cases of typhoid fever were the enlarged mesenteric lymph nodes in all cases (100%), splenomegaly in 4 cases (66.7%), ileocecitis in 1 case (16.7%), enlarged mesenteric lymph nodes and splenomegaly in 4 cases (66.7%), enlarged mesenteric lymph nodes, splenomegaly and ileocecitis in 1 cases (16.7%). 6) The enlarged mesenteric lymph nodes and the abnormalities around the appendix were seen in 7 cases (11.7%), which were confirmed as appendicitis all. 7) The thickening of wall in urinary bladder was seen in 2 cases (3.3%) of acute cystitis and acute hemorrhagic cystitis. 8) The subtle thickening of wall in colon was seen in 1 cases (1.7%) of shigellosis. Conclusions: The enlarged mesenteric lymph nodes, splenomegaly and ileocolitis on the abdominal ultrasonography in patients with fever and abdominal symptoms aree suggestive findings of typhoid fever. The enlarged mesenteric lymph nodes and the abnormalities around the appendix on abdominal ultrasonography make the rapid diagnosis of acute appendicitis and its complications, when physical examination is difficult in small children and diagnosis of their illnesses is obscure in patients with fever and abdominal pain.
