1.  Appendicitis in Children: Evaluation of the Pediatric Appendicitis Score in Younger and Older Children 
Surgery Research and Practice  2014;2014:438076.
Background. This study aimed to evaluate Pediatric Appendicitis Score (PAS), diagnostic delay, and factors responsible for possible late diagnosis in children <4 years compared with older children who were operated on for suspected appendicitis. Method. 122 children, between 1 and 14 years, operated on with appendectomy for suspected appendicitis, were retrospectively analyzed. The cohort was divided into two age groups: ≥4 years (n = 102) and <4 years (n = 20). Results. The mean PAS was lower among the younger compared with the older patients (5.3 and 6.6, resp.; P = 0.005), despite the fact that younger children had more severe appendicitis (75.0% and 33.3%, resp.; P = 0.001). PAS had low sensitivity in both groups, with a significantly lower sensitivity among the younger patients. Parent and doctor delay were confirmed in children <4 years of age with appendicitis. PAS did not aid in patients with doctor delay. Parameters in patient history, symptoms, and abdominal examination were more diffuse in younger children. Conclusion. PAS should be used with caution when examining children younger than 4 years of age. Diffuse symptoms in younger children with acute appendicitis lead to delay and to later diagnosis and more complicated appendicitis.

2.  Pre- and Postoperative Vomiting in Children Undergoing Video-Assisted Gastrostomy Tube Placement 
Surgery Research and Practice  2014;2014:871325.
Background. The aim of this study was to determine the incidence of pre- and postoperative vomiting in children undergoing a Video-Assisted Gastrostomy (VAG) operation. Patients and Methods. 180 children underwent a VAG operation and were subdivided into groups based on their underlying diagnosis. An anamnesis with respect to vomiting was taken from each of the children's parents before the operation. After the VAG operation, all patients were followed prospectively at one and six months after surgery. All complications including vomiting were documented according to a standardized protocol. Results. Vomiting occurred preoperatively in 51 children (28%). One month after surgery the incidence was 43 (24%) in the same group of children and six months after it was found in 40 (22%). There was a difference in vomiting frequency both pre- and postoperatively between the children in the groups with different diagnoses included in the study. No difference was noted in pre- and postoperative vomiting frequency within each specific diagnosis group. Conclusion. The preoperative vomiting symptoms persisted after the VAG operation. Neurologically impaired children had a higher incidence of vomiting than patients with other diagnoses, a well-known fact, probably due to their underlying diagnosis and not the VAG operation. This information is useful in preoperative counselling.

3.  Appendicostomy in Preschool Children with Anorectal Malformation: Successful Early Bowel Management with a High Frequency of Minor Complications 
BioMed Research International  2013;2013:297084.
Aim. The aim of this study is to evaluate postoperatively bowel symptoms of antegrade colon enema through appendicostomies in preschool children with anorectal malformation (ARM). Method. 164 children with ARM operated on with posterior sagittal anorectal plasty were included. The malformations were classified according to Krickenbeck classification. Seventeen children in preschool age had an appendicostomy. The bowel symptoms according to the Krickenbeck follow-up were analysed pre- and postoperatively. All complications were registered. A questionnaire on the use of the appendicostomy was answered. Results. The median age (range) at the time of the appendicostomy was 4 (1–6) years. The observation time was 5 (0.5–14) years. The main indications for appendicostomy were incontinence and noncompliance to rectal enemas. Postoperatively there was a significant decrease in soiling and constipation (P < 0.001). The total complication rate was 43% with infections (29%), stenosis (12%), and retrograde leakage (0). The median time required for giving enema in the appendicostomy was 45 minutes (range: 15–120) once a day varying from 2 times/week to 3 times/day. And: complications are less frequent than in older children. Conclusion. Appendicostomy in preschool children with ARM is a way to achieve fecal cleanness before school start. The infection rate was high, but other complications are less frequent than in older children.

4.  Rectal Atresia—Operative Management with Endoscopy and Transanal Approach: A Case Report 
Minimally Invasive Surgery  2011;2011:792402.
The aim of this study is to present the technique and outcome of the management of a newborn child with rectal atresia. A girl born with rectal atresia was diagnosed during physical examination and confirmed with X-ray. The anatomic appearance of the external anus, and lower pelvis was normal. The rectal ending was located 2 cm cranial from the anus and the distance between the rectal endings was 2 cm. A colostomy was established. At the age of five months the child was operated on with a rectal anastomosis using the endoscopic and transanal approach. Closure of the colostomy was performed at the age of ten months. The rectal anastomosis was treated with rectal dilatation weekly in order to avoid stricture. The patient was faecally continent at followup one and three months postoperatively. In conclusion, the endoscopic and transanal approach is an alternative to other surgical techniques in the management of rectal atresia.

5.  Robotics versus laparoscopy - an experimental study of the transfer effect in maiden users 
Background
Robot-assisted laparoscopy (RL) is used in a wide range of operative interventions, but the advantage of this technique over conventional laparoscopy (CL) remains unclear. Studies comparing RL and CL are scarce. The present study was performed to test the hypothesis that maiden users master surgical tasks quicker with the robot-assisted laparoscopy technique than with the conventional laparoscopy technique.
Methods
20 subjects, with no prior surgical experience, performed three different surgical tasks in a standardized experimental setting, repeated four times with each of the RL and CL techniques. Speed and accuracy were measured. A cross-over technique was used to eliminate gender bias and the experience gained by carrying out the first part of the study.
Results
The task "tie a knot" was performed faster with the RL technique than with CL. Furthermore, shorter operating times were observed when changing from CL to RL. There were no time differences for the tasks of grabbing the needle and continuous suturing between the two operating techniques. Gender did not influence the results.
Conclusion
The more advanced task of tying a knot was performed faster using the RL technique than with CL. Simpler surgical interventions were performed equally fast with either technique. Technical skills acquired during the use of CL were transferred to the RL technique. The lack of tactile feedback in RL seemed to matter. There were no differences between males and females.

6.  Literature Review Comparing Laparoscopic and Percutaneous Endoscopic Gastrostomies in a Pediatric Population 
Objective. This study compares laparoscopic and percutaneous endoscopic gastrostomy (PEG) in a paediatric population to test the hypothesis that there is a difference in the frequency of serious gastrointestinal complications between the two methods. Methods. All reports published between 1995 and 2009 on laparoscopic gastrostomy and PEG in children was included. Prospective and retrospective trials, comparing the two methods or dealing with one of them only were included. Endpoints were accidentally performed gastrointestinal fistula causing an emergency re-operation. The frequency of inadvertent gastroenteric fistulas using the two different techniques was calculated. Results. 822 publications were found when using the search terms: gastrostomy, gastrointestinal complications, and all child: 0–18 years. From these, 54 studies were extracted for this investigation. These studies reported a total of 4331 children undergoing gastrostomy operation, 1027 by using the laparoscopic technique and 3304 using the PEG technique. The number of serious gastrointestinal fistulas to colon or small bowel was 0% and .27%, respectively, P < .05. Conclusions. The results suggest that by performing laparoscopic gastrostomy in children it is possible to avoid the serious intestinal fistula complications caused by a blind puncture through the abdominal cavity when performing the PEG.
