- PURPOSE: Computer-assisted laparoscopic surgery (CALS) in children is increasingly used and has proven to be feasible and safe. However, its full potential remains unclear and clinical comparative studies hardly exist. The aim of this study was to prospectively evaluate our experience with CALS for performing retroperitoneal nephrectomies in children when compared with controls undergoing open surgery in terms of safety, operative time, blood loss, opoid requirements, the duration of hospital stay and complications. CHILDREN AND METHODS: Computer-assisted retroperitoneoscopic nephrectomy was undertaken in ten consecutive children, mean age at the time of surgery 6.4 (SD ± 4.5) years, and compared with a retrospectively collected control group of all other children, mean age 3.9 (SD ± 4.6) years, who underwent the same procedure by conventional open surgery between the years 2005 and 2009. The endpoint of the study was 1 month postoperatively. RESULTS: Nephrectomies were performed in all the children and no child was excluded from the study. There was no per-operative complication in any of the groups. The median (range) operative time was 202 (128-325) and 72 (44-160) min for the CALS and open group, respectively. The blood loss was minimal (<20 ml) for all the patients. The postoperative opoid requirements did not differ. The median (range) postoperative hospital stay was 1 (1-4) and 2 (1-7) days for the CALS and the open group, respectively. One complication in the form of an urinoma appeared 5 days after surgery in the CALS group. CONCLUSION: Computer-assisted retroperitoneoscopic nephrectomy is a safe, feasible and effective procedure in children. Even though operative times are longer the patients benefit from the lower morbidity, improved cosmetics and shorter hospitalization associated with the minimally invasive approach.

- ABSTRACT: 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.

- BACKGROUND: In children, a gastrostomy button was placed as the initial feeding tube, using laparoscopy and a modified surgical technique. The aim of this study was to test the hypothesis that a new surgical procedure developed at our institution would result in fewer postoperative complications. PATIENTS AND METHODS: Sixty-two consecutive children with nutritional problems underwent a video-assisted gastrostomy operation (VAG). The technique requires the use of a 2 or 3 mm laparoscope optic and a 5 mm trocar placed at the exit site chosen for the gastrostomy. A continuous double U-stitch absorbable suture created a purse string suture around the gastrostoma on the stomach and fixated the stomach to the abdominal wall. For comparison, we used a control group of 68 children with nutritional problems operated on with our previously published VAG technique. After surgery, the children were followed up at one and six months and all complications were documented according to a protocol. RESULTS: The two groups of children were comparable with regard to their demographic data. There were no serious intra-operative or postoperative intra-abdominal complications requiring reoperation. There was a significantly lower incidence of the minor complication of granuloma around the gastrostoma in the study group compared with the control group. CONCLUSION: This variation of the surgical technique is simple and effective. It allows primary placement of a gastrostomy button that is functionally and cosmetically comparable to a gastrostomy tube surgically placed by other methods. In this study, the patients had fewer postoperative problems than the control group.

- 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.

- The diagnostic method for Hirschsprung’s disease (HD) involves rectal biopsy to determine the presence of histopathological findings for aganglionosis. Contrast enema (CE) and anorectal manometry help to support the indication for biopsies. Patients with HD lack a rectoanal inhibitory reflex (RAIR) that can be studied using manometry, ultrasound, or a modified contrast enema (CE), which provokes the RAIR with an injection of cold fluid. A question that arises is whether the RAIR also could be visualized with only a specific clinical examination.

- OBJECTIVES:: The aim of this study is to explore the long-term quality of life (QoL) in adults after surgery for Hirschsprung disease in childhood. PATIENTS AND METHODS:: Altogether 51 patients were operated for HD at our center during the period 1969 to 1989. In 2007, the validated instruments for assessing QoL, the SF-36 health survey and the Gastrointestinal Quality of Life Index (GIQLI), were sent to the 47 patients still alive at the time of the study. A retrospective review of the patient records was also done. RESULTS:: Forty-two patients returned both questionnaires (89% response rate) at the median age of 28.5 (range 18-45) years. The median clinical follow-up time was 5.7 years (range 5 months-23 years). At the last clinical control, 4 (9%) patients had a terminal enterostomy, 12 (29%) had soiling, 5 (12%) had constipation, and 2 (5%) experienced recurrent enterocolitis. In contrast to males, the subscores for females were lower for general health and mental health than for an age- and sex-matched general population (P < 0.05). Patients having aganglionosis to the right colon had lower GIQLI scores than those with aganglionosis to the left colon (P < 0.05). In multivariate linear regression analysis, female sex was the only factor associated with lower GIQLI score (P < 0.05). CONCLUSIONS:: The long-term QoL of adults operated for Hirschsprung disease in their youth is satisfactory. Female scores were lower for general and mental health, compared with the matched control group. The study indicates that the longer the aganglionic segment, the greater its impact on QoL in later life.

- INTRODUCTION: The aim of this study was to test the hypothesis that the early functional outcome for patients with rectosigmoid Hirschsprung's disease (HD) is comparable for the Duhamel pull-through procedure and the transanal endorectal pull-through (TERPT) procedure, with less discomfort for the patient postoperatively after the TERPT technique. MATERIAL AND METHODS: Eleven patients operated on with the TERPT technique (T Group) were prospectively registered and compared retrospectively with 18 patients operated on with the Duhamel pull-through (D Group). Data recorded included patient demographics, operative treatment, complications, hospital stay and bowel functions. The follow-up time was limited to 24 months. RESULTS: The T Group started oral feeding sooner, their bowel movements started sooner and they had less need for analgesia postoperatively and a significantly shorter hospital stay. 71% of the patients in the D Group needed re-intervention compared to only 18% of the T Group. Enterocolitis was seen in two patients in both groups. At the last clinical control ten patients had constipation (59%) and three had soiling (18%) in the D Group. Three patients in the T Group had constipation (27%) and one had soiling (9%). CONCLUSION: Our results support the use of the TERPT method rather than the Duhamel pull-through for rectosigmoid HD.
