Mixed acinar-neuroendocrine carcinoma (MANEC) is a malignant pancreatic tumor that rarely occurs in children. It is diagnosed pathologically according to the proportion of neuroendocrine cells present, highlighting the need for surgical biopsy. A 13-year-old boy presented with a 10-cm palpable mass on CT. Surgical resection was performed, and the pathological diagnosis was MANEC. There were no postoperative complications, and the patient was discharged from the hospital 10 days after surgery. He is presently undergoing adjuvant chemotherapy. We reviewed historical MANEC cases published in the English literature. We concluded that pathological analysis of a surgically resected specimen is necessary for an accurate diagnosis of MANEC, and that publication of more cases is needed to determine the optimal management strategy for MANEC.

PURPOSE: The aim of this study was to analyze of the risk factors for surgical procedure on ileo-colic intussusception without leading point in children. METHODS: We retrospectively reviewed medical records of patient treated for ileo-colic intussusception between January 2003 and December 2014. We exclude the patients who had leading point. Because of the large difference on patient's numbers between non-operative group (cases of ileo-colic intussusceptions successfully reduced by air reduction) and operative group (cases underwent operation due to failed air reduction), we compared the data of operative group of patients without leading point between 2003 and 2014 with the data of non-operative group as control group from 2013 to 2014. Clinical features such as gender, age, body temperature, body weight in diagnosis, growth curves for age-gender-body weight, and laboratory data of blood test were compared. RESULTS: In non-operative group, total 94 patients who were treated successfully by the non-operative air reduction. In operative group, total 21 patients treated by surgical procedure. The age under 12 months, weight over upper 75 percentile group, increased segment neutrophil count, decreased hemoglobin level and lymphocyte count were significantly associated with a requirement for surgical procedure. CONCLUSION: We conclude that younger age, higher weight percentile group, increased segment neutrophil, decreased hemoglobin and lymphocyte are the independent risk factors related to operative treatment for ileo-colic intussusception in children. If primary air reduction is failed in patients with such risk factors, operative treatment over ultrasonography or secondary reduction can prevent unnecessary effort and complications, thus emphasizing the consideration of operative treatment when selecting treatment methods.

An 1-month old female newborn was admitted to our hospital because of jaundice which occurred at 2 days after birth. Plain chest X-ray and chest CT revealed a collapsed right middle lobe and lobar emphysema was suspected. Right upper lobectomy of the lung was done and pathologic findings showed an infantile lobar emphysema. After the operation, the newborn was discharged without complication and was followed up through the out patient clinic. Infantile lobar emphysema is rare and male dominant. Left upper lobe of the lung is the most prevalent site. Patients with infantile lobar emphysema complain of respiratory symptoms. We report one case of infantile lobar emphysema on right upper lobe of lung, in a female with no respiratory symptoms.

A 3-year-old boy with purulent otitis media received a chest radiograph as the part of a routine work up. The patient was normal appearing, in no acute distress. The patient's lung and heart sounds were clear and normal. The patient's abdomen was soft, non-distended, and non-tender. An anterior cardiophrenic mass was incidentally identified on the lateral chest radiograph. A computed tomography scan demonstrated a diaphragmatic hernia with bowel loops in the retrosternal space. An exploratory operation revealed a diaphragmatic defect (4 cm in diameter) on the left side of the falciform ligament, through which transverse colon was protruded. There was no hernia sac, and the defect was closed with interrupted No. 2 silk sutures. The child was discharged on the 8th postoperative day without any complications. During 6 months of follow-up period, recurrence was not noticed.

The authors applied anterior sagittal transrectal apporach (ASTRA) for the repair of urethrovaginal fistula which developed after total repair of persistent cloaca. The patient had been diagnosed to have persistent cloaca, double uterus and double vagina, and received PSARP, excision of right-side uterus and vagina, and left vaginal switch operation at 22 months old. After operation, the patient admitted several times due to frequent urinary tract infection and ectopic stone formation in bladder and neovagina. Urethro-neovaginal fistula was confirmed by cystoscopy and corrected with ASTRA. Postoperative voiding cystourethrogram showed no fistula tract. ASTRA showed improved surgical field, minimized ureterocystic damage, and preserved perirectal nerve due to limited incision of rectum.

The use of subcutaneously tunneled, cuffed central venous catheters like Broviac's or Hickman's has increased and complications related to catheter removal has also increased. However, there are only few reports of complications that occur at the time of removal. The authors report an unusual case of catheter fracture during removal of Broviac catheter.

There have been no definitive preoperative diagnostic imaging studies for impalpable testes. We observed the effectiveness of laparoscopy for detecting impalpable testes not identified with ultrasonography (USG) or careful physical examination under general anesthesia. We retrospectively reviewed 117 patients (118 testes) who were operated upon for undescended testes from January 1998 to December 2004. The testes of these patients were palpable in 97(82 %) and impalpable in 21 (18 %). We analyzed the preoperative diagnostic method, site of the testes, operative method and operative findings of the 21 impalpable testes. Preoperative USG and physical examination under general anesthesia were performed on 20 patients, and 12 patients' testes could be localized. Eight patients whose testes could not be localized with USG and physical examination underwent laparoscopy. Seven of the 8 patients had testes in inguinal canal and 4 of these were atrophied and underwent orchiectomy because of atrophy (2) and vanishing (2). Only 1 patient had bilateral intraabdominal testes and one of the testes was atrophied. Laparoscopy was a useful method for detecting impalpable testes, but the clinical application might be limited because the location of atrophic or vanishing testes was mainly inferior to internal inguinal ring.

Conventional treatment of Hirschsprung's disease consists of initial colostomy followed by pull-through operation. But, the treatment of Hirschsprung's disease has been changed along with the development of new surgical technique. Since 1995, endo-GIA has been available at our hospital and one stage Duhamel operation has been performed for neonatal Hirschsprung's disease. Between May 1995 and April 2006, 26 neonates have been treated with one stage pull-through operation by one pediatric surgeon at HanYang University Hospital. The sex ratio was 4.2:1 with male predominance. Clinical findings included abdominal distension (96.2 %), vomiting (50.0 %), delayed passage of meconium (46.2 %), constipation (23.1 %), and enterocolitis (15.4 %). Twenty two cases (84.6 %) were short-segment and 4 cases (15.4 %) were long-segment disease, of which 2 cases were total colon aganglionosis. One of the two patients with total colonic aganglionosis had double transition zones - distal ileum and hepatic flexure of the colon. The average age at operation was 14.56 +/- 8.77 days and the average weight at operation was 3.26+/-0.66 kg. Primary Duhamel operations were performed in 25 patients and Soave-Boley operations was performed in one patient. The endo-GIA 35 (Ethicon, USA) was used from 1995 until 1997, and after that endo-GIA 60 (USSC, USA) was used. The average Duhamel operation time was 88.57 +/- 22.80 minutes. Wound abscess (n = 2) and septum formation (n =1) occurred after Duhamel operation. Bowel function was normalized in 59 % within 3 months and in 95% within 1 year after operation. There was no mortality after one stage pull-through operation in neonate.

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.

Appendicitis is the most common surgical emergency in childhood and the technologic advances of modern medicine have affected the diagnosis and treatment of appendicitis. This study is to evaluate the differences in diagnosis and treatment of appendicitis between present and 10 year ago. The authors retrospectively reviewed the medical records of patients who underwent appendectomy under the diagnosis of the acute appendicitis from July 1993 to June 1995 (Group A, n = 78) and from July 200 to June 2005 (Group B, n = 105). There are no differences between group A and B in mean age (8.5 +/-3.6 vs. 9.3 +/-3.1 year), duration of symptoms (3.0 +/-3.2 vs. 2.6 +/-3.8 days), and postoperative hospital stay(6.6 +/-4.8 vs. 5.8 +/-3.6 days). Preoperative abdominal ultrasonogram and/or computed tomogram was performed in 7 patients (9.0 %) of group A and in 51 patients (58.5 %) of group B. Thirty-six patients (34.3 %) of group B underwent laparoscopic appendectomy, but none in group A. Incidence of a histologically normal appendix decreased from 15.8 % in group A to 4.8 % in group B (p =0.018). This study suggests that utilization of abdominal ultrasonogram or computed tomogram in preoperative evaluation become more popular and surgical treatment of acute appendicitis become more minimally invasive. The rate of negative appendectomy was also reduced compared with 10 year ago.
