Pre-duodenal portal vein in polysplenia syndrome: clinical effects and surgical application.

UNLABELLED: STATING BACKGROUND: Pre-duodenal portal vein (PPV) is a rare congenital anomaly, usually asymptomatic and thus detected only incidentally in adults. It is often associated with other anomalies which can be included into polysplenic syndrome. METHODS: In this case, a 56-year-old-female was admitted for a degenerative ampullome. The preoperative work-up shows a PPV vein, the absence of inferior vena cava retro-hepatic and the presence of an anastomosis between the inferior vena cava and the azygos system and a complete common mesentery. DISCUSSION: Such a discovery is often incidental and of little import; however, it takes on major importance for surgeons because the accidental damage of PPV can lead to serious consequences. CONCLUSION: The aim of this study, based on the embryology of the portal vein focused on a rare anomaly to keep it in mind because this anomaly in case of digestive surgery may need to adjust surgical techniques.

Retroperitoneoscopic vs open dismembered pyeloplasty for ureteropelvic junction obstruction in children.

PURPOSE: To compare the effectiveness, potential advantages and complications of classical open pyeloplasty with retroperitoneoscopic pyeloplasty in children. MATERIALS AND METHODS: Two patient cohorts with confirmed ureteropelvic junction obstruction (UPJO) undergoing open or retroperitoneoscopic pyeloplasty over a 7-year period were analysed comparatively. RESULTS: Operative time was significantly longer in the retroperitoneoscopic group (mean 155 min) compared to the open pyeloplasty group (mean 98 min, P<0.05). Mean hospital stay was shorter in the retroperitoneoscopic group (mean 4.1 days, compared to 5.1 days, open). Complication rates were similar (open, 27% vs retroperitoneoscopic, 29%). These included anastomotic urinary leakage, stenosis and infection. Anastomotic leakage was more common in the retroperitoneoscopic group. There was a 6.6% conversion rate in the retroperitoneoscopic group. Success, defined as improved ultrasonic or renographic parameters, with resolution of symptoms where discernable, was noted in 96% of the open group and 97% of the retroperitoneoscopic group with a mean follow up of 38 and 25 months, respectively. CONCLUSIONS: Retroperitoneoscopic pyeloplasty is as safe and effective as open pyeloplasty. This technique is now our procedure of choice for children>4 months old. The advantages are more obvious in children over 4 years than in infants. This technique remains difficult to perform and teach.

Triple intussusception involving heterotopic pancreatic tissue: a case report.

INTRODUCTION: Intussusception involving heterotopic pancreatic tissue is a rare condition where a portion of the bowel telescopes into an adjacent segment with intraluminal pancreatic tissue as the lead point. Cases of heterotopic pancreas are most often described in the upper intestinal tract, particularly the stomach. CASE PRESENTATION: We present the case of a five-month-old boy of Caucasian ethnicity suffering acute abdominal pain and vomiting with an abdominal mass in the upper right quadrant. Work-up including ultrasound scan confirmed the intussusception. Repeated attempts at radiological reduction and two laparoscopic procedures were performed within 24 hours, which eventually led to the diagnosis of a triple intussusception. CONCLUSION: To our knowledge, such a case of triple intussusception involving isolated heterotopic pancreatic tissue is previously unreported.
