E-mail: ralf-bodo.troebs@marienhospital-herne.de ABSTRACT Wilms tumor surgery requires meticulous planning and sophisticated surgical technique. Detailed anatomical knowledge can facilitate the uneventful performance of tumor nephrectomy and cannot be replaced by advanced and sophisticated imaging techniques. We can define two main goals for surgery: (1) exact staging as well (2) safe and complete resection of tumor without spillage. This review aims to review the anatomical basis for Wilms tumor surgery. It focuses on the surgical anatomy of retroperitoneal space, aorta, vena cava and their large branches with lymphatics. Types and management of vascular injuries are discussed.

The ruptured right lower pole is shown According Farthmann et al.

The perirenal space is the home of the kidneys. The renal fascia, a collagenous connective tissue of mesodermal origin that envelopes the kidney, is responsible for this compartmentalization. The kidney is enveloped by the anterior and posterior laminae of the renal fascia and fatty tissue inside and outside the fascia. There is some medial fixation with the adventitial covering of renal vessels and aorta or inferior vena cava (IVC).[4] Figure 2: Peri- and pararenal hematoma after traumatic renal rupture (CT Scan) For example, Figure 2 depicts a case of traumatic renal rupture.

Early ligature of the vein has the theoretical advantage of preventing hematogenous tumor spread. [8, 16, 17] However, this was never confirmed by a prospective trial. On the other hand, primary ligature of the artery is recommended for prevention of tumor swelling and rupture. [7,10,18] There is no consensus in literature regarding the sequence of vessel ligature. Selected international standard publications recommend early control of the hilum. However, this is often not feasible with extremely large tumors; mobilization of the tumor mass must first occur to allow exposure of the hilar vessels.[16,19] The current SIOP 2001/German Society of Pediatric oncology protocol recommends initial ligature of the artery. When feasible, we follow this recommendation. During removal of left renal tumors, damage to the aorta, superior mesenteric artery (SMA), and right renal artery has been reported to occur. These vessels are in close proximity to the tumor mass, and if the aorta and IVC separate by tumor or lymphatic infiltration, they are threatened during removal of the left kidney.

In contrast to SMA, dissection of the stem of inferior mesenteric artery (IMA) is commonly tolerated without disastrous consequences. Generally the marginal artery, also known as arcade of Riolan arch, (synonymously marginal artery of Drummond), sufficiently connects SMA with IMA [Figure 6]. However, only small collaterals exist at the splenic flexure.[22] In addition, the ascending arch of the left colic artery (AALCA) is present in at least two third of cases.

E-mail: avinashdes999@yahoo.co.uk ABSTRACT Vocational and social issues affect rehabilitation and development of patients with cleft lip and cleft palate. However, psychological problems like lowered self esteem and difficulties in social interaction have also been noted in them. Not many pediatric reconstructive surgery teams have a psychiatrist on their panel. It is likely that psychological problems are higher in incidence than literature actually suggests. Hence it is very essential that such cases are identified by the surgical team to maximize positive outcome of surgery and rehabilitation.

E-mail: meh_hosseinpour@yahoo.com ABSTRACT Background: The diagnosis of Hirschsprung’s disease (HD) based on the absence of ganglion cells in hemotoxilin and eosin (H and E) staining has limitations in the diagnosis of immature ganglion cells in neonates. Methods: In this prospective study, 54 biopsies taken from suspectedHD patients (five mucosal specimens and 49 full thickness specimens) were studied. In the laboratory, after preparing sections of paraffin embedded tissues, H and E staining slides were compared with immunohistochemical (IHC) staining including: S100, NSE, CD117, CD56, Cathepsin D, Vimentin, bcl2, GFAP, Synaptophysin and chromogranin. Results: The study revealed 30 negative (absence of ganglion cells) cases (55.5%), 17 positive cases (31.04%) and seven suspected cases (12.9%) ganglion cells on the H and E staining. On IHC staining with CD56 and Cathepsin D, all of the 17 positive cases detected through H and E, were confirmed for having ganglion cells and out of 30 cases reported negative on H and E staining, 28(93.3%) were reported negative and two (6.7%) positive by IHC staining. Of the seven suspected cases H and E staining), IHC staining detectedganglion cells only in five slides; two remained negative. Conclusions: IHC staining using CD56 and Cathepsin D improved the accuracy of diagnosis in HD when used in addition to H and E staining technique, especially for negative or suspicious slides. Among the IHC staining markers, S100, NSE, CD117, Vimentin, bcl2, GFAP, Synaptophysin and chromogranin were suboptimal in comparison to CD56 and Cathepsin D.

E-mail: Andrew.Barker@health.wa.gov.au ABSTRACT Background: Flexible ureterorenoscopy (FUR) and laser lithotripsy (LL) are techniques used in the management of upper urinary tract disorders. These techniques, so far established in adults, are now being used in children as well. We report our experience with 26 cases of pediatric upper urinary tract disorders treated using these techniques. Methods: In the period from 1997 to 2006, FUR was performed in 26 children (14 males and 12 females) in the age group of three months to 15 years with a mean age of 8.2 years. Twenty five were stented prior to undergoing FUR and 24 presented with suspected upper tract stones (17 pelvicalyceal and seven midureteric). Two cases showed JJ stent migration post-pyeloplasty. Results: Eight cases involved diagnostic procedures. Six excluded the presence of renal calculi, one had focal medullary sponge kidney, and one had calcified papillae. There were 15 cases of therapeutic FUR. Of these, 12 had LL with only one had incomplete stone fragmentation which subsequently passed spontaneously. Other therapeutic procedures included removal of migrated JJ stents and FUR with the basket removal of a midureteric calculus. Three cases failed ureterorenoscopy due to technical difficulties. The overall success rate was 88.5% for FUR. Conclusion: FUR and LL are valuable minimally invasive techniques for the examination and treatment of pediatric upper urinary tract conditions. Preoperative stenting improves passage of the ureteroscope and with progressive miniaturization of instruments, the lower weight limit will decrease.

A 9.5/11.5Fr or 10/12Fr Cook ureteral access sheath was used in all children who had LL. The ureteroscope was advanced up to the kidney under fluoroscopy over a guide wire and, during LL, a second guide wire was left alongside the ureteroscope for safety. With the ureteroscope in the renal pelvis, each calyx was individually assessed for calculi. Once the calculus was located a 200micron laser fiber was used under direct vision to vaporize the stone to fragments one mm or smaller in size. Post LL, the children stayed overnight with a 3F ureteric catheter draining the upper tract strapped to a Foley indwelling urinary catheter, which was removed the next day.

E-mail: dr_veenasingh@yahoo.co.in ABSTRACT Aim: Traditionally, ligation of hernial sac during orchiopexy is considered mandatory to prevent postoperative development of hernia. A prospective study was carried out to see if it is actually required based on the fact that any peritoneal defect closes within 24 hours by metamorphosis of the in situ mesodermal cells. Methods: Fifty cases of undescended testis, age ranging from eight months to 12 years were enrolled. All of them underwent standard orchiopexy without ligation of the hernial sac. Results: Follow up of all cases ranged between 1.5 years to three years. Not a single case was reported with evidence of hernia. Conclusions: It is unnecessary to ligate the hernial sac during orchiopexy. KEY WORDS: Ligation of hernial sac, orchiopexy, undescended testis DOI: ***** InTRodUcTIon the ligation of the hernia sac.
