Appendicitis is a common cause of acute abdomen in pediatrics. Periappendiceal abscesses are frequently found in the pediatric population. Acute appendicitis in children can, at times, be a difficult clinical diagnosis because of its highly variable history? and physical manifestations and its unpredictable course. Despite the uncertainty of the diagnosis, appendicitis demands prompt treatment because of the risk of perforation, which occurs in approximately one third of cases. Urological manifestations of appendicitis and appendiceal abscess can vary. Acute appendicitis presenting with ureteral stenosis and hydronephrosis is very rare. Here, we report a case of acute appendicitis with perforation and left hydronephrosis in a 3-year-old female. This case presents a 3-year-old girl with dysuria having hydronephrosis that originated from a perforated appendix.

Pediatric laparoscopic appendectomy is controversial particularly in complicated appendicitis. We evaluated the outcomes of laparoscopic appendectomy (LA) and open appendectomy (OA) in simple appendicitis and complicated appendicitis respectively. Since June 2004, initial LA has been our policy in all appendicitis including complicated ones. A total of 160 patients were included in this study, consisting of 80 OA (August 2001 - August 2003) and 80 LA (June 2004 - June 2006). We compared the operating time, the length of hospital stay, the length of antibiotics use, and the postoperative complications between LA and OA. In simple appendicitis (73), there were no differences between LA and OA. However in the 87 patients with complicated appendicitis, the operating time was longer in LA (64.8 min vs. 50.2 min) but the length of hospital stay was shorter in LA than OA (8.5 days vs. 9.6 days). There was one complication in simple appendicitis group and six in complicated appendicitis group (3 cases in LA, 3 cases in OA). There was no difference in the results of LA versus OA in simple appendicitis. Therefore for simple appendicitis, LA is recommended in consideration of the cosmetic effect (fewer scar). In complicated appendicitis, early discharge was an advantage and there were no differences in complications in LA despite a longer operative time. So we conclude LA can be considered as the first choice of treatment for all pediatric appendicitis including complicated appendicitis. To confirm our impressions, more well controlled randomized prospective studied need to be done.

Objective: Acute appendicitis is one of the most urgent surgical problems. Several factors have been considered as predictors of perforation, but this study focused on the change in pain pattern. The degree of pain and progression of appendicitis were analyzed assuming that the pain intensity would increase until the perforation and the degree of pain would decrease immediately after the perforation occurred. Methods: In this study, 385 out of 467 patients, who were diagnosed with appendicitis in a single institution and aged between 15 and 65 years, were reviewed retrospectively. The patients' pain scores and the diameters of appendices were analyzed along with the accompanying complications. Correlation analysis and a Student's t-test were performed. Results: In patients with complicated appendicitis, the mean numerical rating scale (NRS) was slightly higher than that of simple appendicitis, but there was no significant difference in the absolute value. Only the size of the appendix showed meaningful differences according to the combined computed tomography findings. The NRS distribution or appendiceal size did not correlate with the time duration from symptom onset. Conclusion: The appendiceal size tended to increase with progressing appendicitis. No significant correlation was observed between the patient's pain level and complications. The time duration from symptom onset did not show a relationship with the progression of appendicitis.

Purpose: Appendicitis is the most frequent urgency in pediatric age; the aim of this study was to investigate the association of quarantine for severe acute respiratory syndrome coronavirus 2 pandemic and the incidence of pediatric appendicitis in a specific macro area. Methods: We retrospectively analyzed the medical records of consecutive patients who underwent surgical exploration for acute appendicitis in the period March-April since 2014. This specific quarantine period was divided into two phases as indicated by National government. Patient data, demographics, characteristics and outcomes were studied and evaluated comparing patients treated during quarantine especially phase 1 vs. phase 2 (March-April 2020). Results: After reviewing medical charts following the inclusion and exclusion criteria, 155 patients were studied; focusing on the final outcome, it is possible to show a decreased amount of appendicitis during phase 1 and a progressive increase during phase 2; respect to previous years, there was a statistical increase in severity of appendicitis during quarantine (gangrenous vs. phlegmonous appendicitis). Conclusion: During this specific quarantine there was a reduction in appendicitis and a progressive increase during phase 2. These results offer new perspective among disease incidences during lockdown.

Intestinal obstruction secondary to intraabdominal adhesion is a well-known postoperative complication occurring after appendectomy. The aim of this study was to measure the incidence and clinical manifestations of mechanical intestinal obstruction after appendectomy for perforated appendicitis. We reviewed all of the children (age <16 years) who had been treated for appendicitis at Asan Medical Center between January 1996 and December 2001. Inclusion criterion included either gross or microscopic evidence of appendiceal perforation. Exclusion criteria were interval appendectomy, and patients immune compromised by chemotherapy. Associations of intestinal obstruction with age, sex, operation time, and use of peritoneal drains were analyzed. Four hundred and sixty two open appendectomies for appendicitis were performed at our department. One hundred and seventeen children were treated for perforated appendicitis (78 boys, 39 girls). The mean age was 8.9 years (range 1.5 to 14.8 years). There were no deaths. Eight patients were readmitted due to intestinal obstruction, but there was no readmission due to intestinal obstruction in patients with non-perforated appendicitis. The interval between appendectomy and intestinal obstruction varied from 12 days to 2 year 7 months. Four patients needed laparotomies. In three of four, only adhesiolysis was performed. One child needed small bowel resection combined with adhesiolysis. There was no significant association between age or sex and the development of intestinal obstruction. This was no association with operative time or use of peritoneal drain. Patients who required appendectomy for perforated appendicitis have a higher incidence of postoperative intestinal obstruction than those with nonperforated appendicitis. For the patients with perforated appendicitis, careful operative procedures as well as pre and postoperative managements are required to reduce adhesions and subsequent bowel obstruction.

Appendicitis is a common disease in children. But left lower abdominal pain in acute appendicitis is a rare clinical feature. A 6 year-old-girl complained of left sided abdominal pain for 2 days. Past medical history was not contributory. Abdominal tenderness and guarding in left lower quadrant were noticed. Abdominal sonography and abdominal computed tomography scan demonstrated reversed position between superior mesenteric artery and vein, and a mass in the left lower quadrant abdomen suggesting appendicitis. Acute appendicitis in left lower quadrant, associated with intestinal malrotation, was found at laparatomy.

Purpose: Pediatric acute appendicitis has a stable incidence rate in Western countries with an annual change of -0.36%. However, a sharp increase was observed in the Asian region. The Indonesian Health Department reveals appendicitis as the fourth most infectious disease, with more than 64,000 patients annually. Hence, there is an urgent need to identify and evaluate the risk factors and diagnostic modalities for accurate diagnosis and early treatment. This study also clarifies the usage of pediatric appendicitis score (PAS) for children <5 years of age. Methods: The current study employed a cross-sectional design with purposive sampling through demographic and PAS questionnaires with ultrasound sonography (USG) results. The analysis was performed using the chi-square and Mann-Whitney tests and logistic regression. Results: This study included 21 qualified patients with an average age of 6.76±4.679 years, weighing 21.72±10.437 kg, and who had been hospitalized for 4.24±1.513 days in Siloam Teaching Hospital. Compared to the surgical gold standard, PAS and USG have moderate sensitivity and specificity. Bodyweight and stay duration were significant for appendicitis (p<0.05); however, all were confounders in the multivariate regression analysis. Incidentally, a risk prediction model was generated with an area under the curve of 72.73%, sensitivity of 100.0%, specificity of 54.5%, and a cut-off value of 151. Conclusion: PAS outperforms USG in the sensitivity of diagnosing appendicitis, whereas USG outperforms PAS in terms of specificity. This study demonstrates the use of PAS in children under 5 years old. Meanwhile, no risk factors were significant in multivariate pediatric acute appendicitis risk factors.

Objectives: The aim of this study is to report the effect of pharmacopuncture on the treatment of acute appendicitis. Methods: A twenty-nine-year old male patient who was diagnosed with acute appendicitis was treated by V pharmacopuncture at Maengjang-point (盲腸点) and tender points on the abdomen for three days. Results: After three days of V pharmacopuncture treatment, appendicitis was improved. Conclusions: This case has shown the possibility of treating acute appendicitis with Korean medicine, rather than using western treatments such as surgery. Therefore, pharmacopuncture may be a possible treatment candidate for appendicitis.

Diagnosis of acute appendicitis in children is sometimes difficult. The aim of this study is to validate a clinical scoring system and ultrasonography for the early diagnosis and treatment of appendicitis in childhood. This is a prospective study on 59 children admitted with abdominal pain at St. Mary's Hospital, the Catholic University of Korea from July 2002 to August 2003. We applied Madan Samuel's Pediatric Appendicitis Score (PAS) based on preoperative history, physical examination, laboratory finding and ultrasonography. This study was designed as follows: patients with score 5 or less were observed regardless of the positive ultrasonographic finding, patients with score 6 and 7 were decided according to the ultrasonogram and patients above score 8 were operated in spite of negative ultrasonographic finding. The patients were divided into two groups, appendicitis (group A) and non-appendicitis groups (group B). Group A consisted of 36 cases and Group B, 23 cases. Mean score of group A was 8.75 and group B was 6.13 (p<0.001). Comparing the diagnostic methods in acute appendicitis by surveying sensitivity, specificity, positive predictive value, negative predictive value, and accuracy, PAS gave 1.0000, 0.3043, 0.6923, 1.0000, and 0.7288, and ultrasonography gave 0.7778, 0.9130, 0.9333, 0.7241, and 0.8300 while the combined test gave 1.0000, 0.8696, 0.9231, 1.0000, and 0.9490, respectively. Negative laparotomy rate was 3 %. In conclusion, the combination of PAS and ultrasonography is a more accurate diagnostic tool than either PAS or ultrasonography.

Purpose: Laparoscopic appendectomy (LA) has become a gold standard for children even in complicated appendicitis. The purpose of this study was to compare the postoperative surgical site infection rates between laparoscopic and open appendectomy (OA) group in pediatric complicated appendicitis. Methods: A total of 1,158 pediatric patients (age ${\leq}$ 15 years) underwent operation for appendicitis over a period of 8 years. Among these patients, 274 patients (23.7%) were diagnosed with complicated appendicitis by radiologic, operative and pathologic findings, and their clinical outcomes were retrospectively analyzed. Results: Of the 274 patients with complicated appendicitis, 108 patients underwent LA and 166 patients underwent OA. Patients in the LA group returned to oral intake earlier (1.9 days vs. 2.7 days; p<0.01) and had a shorter hospital stay (5.0 days vs. 6.3 days; p<0.01). However, rate of postoperative intra-abdominal infection (organ/space surgical site infection) was higher in the LA group (LA 15/108 [13.9%] vs. OA 12/166 [7.2%]; p<0.01). Readmission rate was also higher in the LA group (LA 9/108 [8.3%] vs. OA 3/166 [1.8%]; p<0.01). Conclusion: The minimally invasive laparoscopic technique has more advantages compared to the open procedure in terms of hospital stay and early recovery. However, intra-abdominal infection and readmission rates were higher in the laparoscopy group. Further studies should be performed to evaluate high rate of organ/space surgical infection rate of laparoscopic procedure in pediatric complicated appendicitis.
