[Case of splenogonadal fusion with genital malformation].

A case of splenogonadal fusion associated with a posterior hypospadias is presented. The testis was ectopic, leading to realize an arteriography. The vascularization of the splenogonadal fusion was on the dependance of the renal artery. The testis and splenic tissues were separated, with anastomosis between the spermatic vessels and the epigastric one; this anastomosis was unsuccessful. Eighty nine examples of splenogonadal fusion have been reported. They are divided into two forms: the continuous type is often associated with other malformations (limb, micrognathia). These associations are explained by the embryology. The treatment must be conservative.

[Portal hypertension in children. Therapeutic approach in cases of failure of a portosystemic shunt].

88 porto systemic shunts were performed between 1977-1985; 14 failures were observed. These failures occurred in ten children with extra-hepatic portal obstruction and in four with intra-hepatic obstruction. The treatment of these failures was different in these two groups: 7 reoperations in the extra-hepatic obstruction, none in the intra-hepatic. That reoperation is often not suitable in the intrahepatic obstruction because of the hepatic failure. The use of sclerotherapy or the beta receptor blocking agents is discussed in this group.

Radiological anatomy of the bile ducts based on intraoperative investigation in 250 cases.

Intraoperative cholangiograms were studied in 250 patients. Analysis of the data obtained led to the establishment of a protocol for intraoperative cholangiography aimed at identification of anatomical anomalies and variations. Diagnosis of the latter must be achieved in order to avoid possible intraoperative complications. The common hepatic duct was formed by the junction of the right and left hepatic ducts in 52% of the cases studied. Absence of convergence of the posterior and anterior rami of the right hepatic duct was found in 30% of cases. Anatomical variations of the right sectorial duct system were seen in 12% of cases. Conversely, variations of the left sectorial duct system were rarely seen (2% of cases). Careful examination of the intraoperative cholangiograms led us to suspect certain anatomical variations in close to 1% of cases. These variations included abnormal hepatocystic duct, which if undiagnosed could lead to choleperitoneum or inadvertent ligation of the right hepatic duct. An abnormal hepatocystic duct terminating on the gall bladder was found in one patient. Study of the origin of the common bile duct allowed us to define the mode of termination of the cystic duct (on the right margin of the common hepatic duct in 80% of cases) and to identify a short choledochus in 2% of cases. Finally, variations of the duodenal termination of the common bile duct were studied and reflux into the pancreatic duct was seen in 27% of cases. However, the pathological significance of such reflux was rarely found.

[Partial nephrectomy in nephroblastoma].

The authors analyse their 18 partial nephrectomies performed on 12 children with either a bilateral or a Wilms' tumor of a single remaining kidney: 13 affected kidneys were otherwise normal, the 5 others were sites of a diffuse nephroblastomatosis. The short term results are good (one technical failure only). The long term results were excellent for Wilms' tumors on otherwise healthy kidneys (no recurrence), as opposed to kidneys with diffuse nephroblastomatosis, where invariable tumor recurrence was observed. Because of the low risk of tumor development in the controlateral healthy kidney, and the established value of classical total nephrectomy, the authors, however, consider partial nephrectomy only in highly selected cases of unilateral nephroblastoma.

[Injuries of the liver in children. Review apropos of 30 cases].

Between 1970 and 1983, 30 children have been treated for a liver trauma. 16 were from 5 to 10 years old. 6 had solitary hepatic lesions and 24 had visceral or polytraumatic associated lesions. All but one were operated and 27 underwent an emergency laparotomy. Superficial tears and subcapsular hematoma were found in 11 cases while penetrating wounds (14), vascular injuries (3) and ruptures (2) represent 2/3 of the whole lesions. In five cases, hepatectomy was necessary. Half of the 6 deaths result of a vascular injury, the others of the associated lesions. We have a resolutely surgical behavior when collapse or polyvisceral lesions are patent, while in isolated blunt injury a single clinical and echographic follow up is justified. A CT scan is necessary when a penetrating wound is suspected completed with an angiography.

[Treatment of extra-vesical ureteroceles associated with pyeloureteral duplication in children].

The authors report their experience of the treatment of the extra-vesical ureteroceles associated with pyelo-ureteral duplication. Twelve nephrectomies were performed because of the destruction of the kidney. A one stage complete repair (upper partial nephroureterectomy and excision of the ureterocele) was performed in 24 cases. It is a difficult technique but achieves good results (only three reoperations). The upper pole partial nephroureterectomy (simplified method, 31 cases) is easier to perform; twelve re-operations were necessary due to bladder outlet obstruction or vesicoureteral reflux. This complication is impossible to anticipate after the simplified method. Long term follow up is therefore essential after upper pole partial nephroureterectomy.

[Wirsung's duct hemorrhage in chronic pancreatitis. Report of 4 cases and study of the literature].

Hemorrhage from Wirsung's canal complicated chronic pancreatitis in 4 patients. Excision (2 cephalic and 1 corporeocaudal) in 3 cases provided successful results, the 4th patient dying from intraperitoneal rupture of the false cyst responsible for the hemorrhage, during recurrence of the latter after simple ligature. A literature review indicated pancreatic disease, mainly chronic, as the cause in 76.5% of the 64 cases documented. Diagnosis is difficult from clinical findings, and is dependent mainly on results of endoscopy and particularly retrograde catheterization of the papilla, while arteriography is essential for confirmation of the diagnosis and the site of the lesion, and for assisting choice of therapy. When a chronic pancreatitis exists, the only logical attitude is selective excision, mortality being minimal (5%). Embolization could be a valid method for ensuring hemostasis temporarily to allow delayed radical surgery.

[Problems posed by massive hemorrhages of colorectal origin. Apropos of 12 case reports].

Urgent surgical operation to treat massive hemmorrhage of colorectal origin was necessary in 12 patients: --colon diverticulosis: 7 cases, --cecal angiodysplasia: 1 case, --pancreatocolic fistula: 1 case, --ischemic colitis: 2 cases, --post-radiation therapy rectitis: 1 case. Lesions exclused from discussion in this report and provoking hemorrhage were colorectal tumors, chronic inflammatsry colitis, rectosigmoid angiomatosis, and post-traumatic or iatrogenic lesions. After a definition of massive hemmorrhage based on pre-operative transfusional requirements, the exploratory procedures necessary for localization of the site of the hemorrhage or for detecting a right colon angiodysplasia are discussed. Bimesenteric arteriography represents the exploration of choice, but its usefulness is limited in patients with several risk factors and an average age of 70 years. The respective values of a barium enema and peroperative endoscopy in this particular context are also discussed. Elective surgery should be performed only when the exact site of bleeding has been determined or when an angiodysplasia is present. Particular problems arise when treating diffuse colon diverticulosis hemorrhage, and that provoked by the association of an angiodysplasia and a diverticulosis, as well as hemorrhagic lesions that may require emergency therapy in much rarer affections: ischemic colitis, pancreatocolic fistula, iliosigmoidal fistula, colorectal varices, colon and rectal ulcers, and colorectal radiolesions.
