Laparoscopy to Assist Surgical Decisions Related to Necrotizing Enterocolitis in Preterm Neonates.

Aim of the Study: Necrotizing enterocolitis (NEC) is a devastating intestinal disease that mainly affects preterm infants. Despite advancements in neonatal care, mortality of NEC remains high and controversies exist regarding the most appropriate time for surgical intervention and challenging of diagnosing NEC. Using a pig model of NEC, we aimed to examine if laparoscopy is feasible for diagnosis of NEC. Methods: Preterm caesarean-delivered piglets (n = 42) were fed with increasing amounts of infant formula up to 5 days to induce NEC. On days 3-5, we examined the intestine by laparoscopy under general anesthesia. The bowel was examined by tilting the pigs from supine position to the left and right side. Macroscopic NEC lesions were identified and graded according to a macroscopic scoring system, then a laparotomy was performed to rule out any organ injury and missed NEC lesions. Results: Visible NEC lesions (scores 4-6) were found in 26% (11/42) of the piglets. A positive predictive value of 100% was found for laparoscopy as a diagnostic marker of NEC in both colon and the small intestine. One piglet had a higher NEC score in the small intestine found at laparotomy, than at laparoscopy, resulting in a sensitivity of 67%, and a specificity of 100% for the small intestine. Conversely, both the sensitivity and specificity for colon was 100%. Acceptable levels of agreement was found, with minimal proportional bias in both colon and the small intestine for laparoscopy and laparotomy. Ultrasound examination had a lower sensitivity of 67% and specificity of 63%. All piglets were respiratory and circulatory stable during the procedure. Conclusions: In preterm piglets, laparoscopy is a feasible tool to diagnose NEC with a high positive predictive value and a high specificity.

Complication rate after circumcision in a paediatric surgical setting should not be neglected.

INTRODUCTION: As a consequence of the discussion on whether the health benefits of newborn male circumcision outweigh the risks and the discrepancies in reported figures of complications, we evaluated our results from a paediatric surgical department. MATERIAL AND METHODS: Patient file data from children who had undergone ritual circumcision in the 1996-2003 period were retrieved. Complications recorded until December 2011 were noted. RESULTS: Circumcision in 315 boys aged from 3 weeks to 16 years (median five years) were evaluated. A total of 16 boys (5.1%) had significant complications, including three incomplete circumcisions requiring re-surgery, two requiring re-surgery six months and five years postoperatively due to fibrotic phimosis and two requiring meatotomy due to meatal stenosis two and three year postoperatively. Acute complications included two superficial skin infections one week postoperatively and five cases with prolonged stay or re-admissions for bleeding the first or second postoperative day, whereof two underwent operative treatment. Finally, two had anaesthesiological complications leading to a need for overnight surveillance, but no further treatment. DISCUSSION: Parents should be counselled and be required to provide informed consent that any health benefits of childhood circumcision do not outweigh the reported complication rate and that therefore they should weigh the health benefits against the risks in light of their religious, cultural and personal preferences. As ritual circumcision is legal, a strong focus on high surgical/anaesthesiological standards is needed to avoid complications. FUNDING: not relevant. TRIAL REGISTRATION: not relevant.

Colonoscopy results are not enhanced by use of magnet endoguide in specialist practice.

INTRODUCTION: It is discussed whether the use of a magnetic positioning device (OLYMPUS; UPD (unit of magnetic positioning device)) enhances the success of the colonoscopic procedure. Concern for patient compliance and endoscopic efficiency has been voiced in connection with the implementation of colon cancer screening. UPD has been proposed as a tool for optimization of results and reduction of patient discomfort. In this study, we aimed to qualify the debate by examining the success rate and patient discomfort in an unselected colonoscopy population referred to specialist clinics with experienced investigators. Furthermore, the study assessed the effect of using a UPD. MATERIAL AND METHODS: A total of 1,068 consecutive patients referred for colonoscopy were enrolled and randomised for investigation with or without use of UPD. The evaluation endpoints were: success rate (coecum visualised, ileal intubation was carried out at the investigator's discretion), duration of procedure, and patient discomfort indicated by the patient as a visual analogue scale score. RESULTS: No significant differences between the two investigational procedures were demonstrated in relation to the chosen endpoints. CONCLUSION: UPD is convenient to have, but not a necessity for colonoscopy. FUNDING: The study was supported by the Danish Association of Medical Specialists. TRIAL REGISTRATION: The study was approved by the Danish Data Protection Agency, journal no. 2009-41-3716, the National Ethics Committee, journal no.: H-1-2009-80, and registered with ClinicalTrials.gov., protocol no: NCT01055782.

[Pancreatic trauma in children--operative versus non-operative treatment]. / Pancreastraumer hos børn--operativ versus nonoperativ behandling.

Pancreatic trauma is more frequent in children than in adults and is often caused by trauma to the upper part of the abdomen. Mortality is low, but morbidity is high. Pancreatic trauma can be treated operatively or non-operatively, but there is disagreement about the optimal treatment strategy for patients with severe pancreatic lesions. In general, good results are achieved with non-operative treatment and secondary surgery is avoided, but prospective trials are needed to evaluate the method.
