- One of the complex upper urinary tract anomalies is a duplicated collecting system. In cases with a functioning upper moiety, ureteroureterostomy (UU) is the preferred operation to redirect the urine to the normal collecting system. Although open UU is a well-described operation, experience with laparoscopic repair pediatric patients is scarce. We describe the successful application of laparoscopic UU in 2 children and suggest that laparoscopic UU for the duplicated collecting system is a promising minimally invasive procedure.
- The laparoscopic approach to giant ovarian cysts in pediatric population may be difficult regarding the risk of cyst rupture and limited working space. We herein report a 16-year-old adolescent girl that presented with a giant ovarian cyst. To reduce the limitations of the laparoscopy, we performed laparoscopy after draining the cyst under ultrasonographic guidance. Under local anesthesia, a nephrostomy catheter was placed into the cyst by the Seldinger technique. During laparoscopy, abdominal cavity was explored by the scope and then the nephrostomy catheter was removed.
- For the treatment of recurrent bleeding despite sclerotherapy or clinically significant hypersplenism, portosystemic shunt procedures should be performed in cases of extrahepatic portal hypertension caused by extrahepatic portal vein thrombosis. A novel alternative to portosystemic shunt procedures in extrahepatic portal hypertension is mesenterico-left portal bypass. Portal vein thrombosis is bypassed by an autologous vein graft (usually left internal jugular vein) interposed between superior mesenteric vein and left portal vein.
