Persistent omphalomesenteric duct causing small bowel obstruction in children

Small bowel obstruction is a common surgical emergency and a frequently encountered problem in abdominal surgery, but persistent omphalomesenteric duct as a cause of this condition is an exceptional finding. To report through this observation an omphalomesenteric duct causing small bowel obstruction in children. A 10-years-old male patient without medical history, and specially without umbilical secretion or umbilicoileal fistula, presented with colicky abdominal pain, vomiting, absence of passage of gas and feces, and abdominal distension of 24 hours duration. Physical examination and blood tests were normal. Abdominal X-ray showed small bowel obstruction. In exploratory laparotomy, persistent omphalomesenteric duct [10cm] causing volvulus of small bowel was identified and resected. The patient had an uneventful recovery and was discharged on the 5th postoperative day. Although persistent omphalomesenteric duct is an extremely infrequent cause of small bowel obstruction in children patients. The practitioner has to think of this etiology in front of every patient without surgical histories presenting an occlusive syndrome to avoid the complications: occlusion and hemorrhage

Indications for Nephrectomy in children: what has changed?

The last decade has witnessed significant refinements in preoperative diagnostic evaluation and an improvement in surgical techniques and postoperative management for paediatric patients. There has been an improvement in our understanding of the natural history of some congenital renal anomalies which has caused some changes in management approach. To review the indications for nephrectomy in children between 1996 and 2008, at the departement of paediatric surgery, children's hospital in Tunis. There were 80 nephrectomies. A retrospective review of the patients' notes was performed. The 13-year period was divided into two halves [1996-2000 and 2001-2008] which were then compared. The total number of nephrectomies per year significantly increased over the period of the study [4,6 and 8 nephrectomies per year for 1996-2000 and 2001-2008, respectively; P< 0.05], as did the number of nephrectomies for Multicystic dysplastic kidney [MCDK] [zero and 5 for 1996-2000 and 2001-2008, respectively] and wilms'tumour [8,3% and 29,16% for 1996 - 2000 and 2001 - 2008, respectively].Wilms' tumour, vesico-ureteric reflux [VUR] and pelvi-ureteric junction [PUJ] obstruction accounted for more than half of the nephrectomies [80% and 58% for 1996-2000 and 2001-2008, respectively]. The proportion of nephrectomies performed for VUR did not change [15% and 12% for 1996-2000 and 2001-2008, respectively] but fewer nephrectomies were performed for pelvi-ureteric junction [PUJ] obstruction in the second half of the study period [44% and 4,16% for 1996-2000 and 2001-2008, respectively ;P<0.05]. The total number of nephrectomies, including partial nephrectomies, has increased significantly. The decrease in nephrectomies for PUJ obstruction could be accounted for by a more aggressive approach in the management and follow up of prenatally diagnosed hydronephrosis. Of note is that there was no significant change in the proportion of nephrectomies performed for VUR. On the contrary, the proportion of nephrectomies increased for neoplastic lesions and MCDK
