[Total colonic aganglionism (author's transl)].

Total colonic is the most frequent form of extensive aganglionism. Diagnosis is difficult, but it must be taken in mind whenever either muscoviscidosis or ileal atresia are considered. Nine cases out of a series of 319 aganglionisms seen between 1957 and 1977 are reported. Ileostomy can be lifesaving but Duhamel-Lester Martin technique must be elected as a definitive treatment. The modification proposed by the authors, carried out in three cases, can be performed as a first-choice operation in the newborn. The long term results in these three cases are compared to those of other techniques. A general review of the problem is made.

[Effects of parenteral nutrition solutions on the venous walls (an experimental study) (author's transl)].

Lesions (thrombosis, intimal damage, perivascular inflammation) of the marginal ear vein of domestic rabbits were studied 48 hours after infusions of parenteral feeding solutions administered through a butterfly-type 25 needles. Six-hour infusions with a rather diluted solution (12 g dextrose, 1.25 g. aminoacids, 1.5 mEq., Na, Cl, K and PO4 and 1.5 mEq. Ca and Mg per 100 ml.) with osmolality of 930 and pH of 6.9 were slightly harmful, while the lesions were considerable after 12-hours infusions. A more concentrated solution (15.83 g. dextrose, 2.08 g. aminoacids, 2.5 mEq. Na, Cl, K and PO4 0.2 MEq. Ca and Mg per 100 ml.) with osmolality of 1,600 and pH 6.7 produced severe lesions both after 6 and 12-hours infusions. Similar results were obtained with a mixture of this solution with intralipid at clinical doses (4 g. fat for 100 ml. of solution). This mixture had 1,280 mOsm/1. and pH of 6.7. Rather surprisingly the lesions were even more marked when intralipid alone was infused (osmolality 317, pH 7.5). These results lead to the conclusion that practically all fluids used for parenteral feeding purposes either centrally or peripherally, are considerably harmful for the venous wall after a few hours of infusion, probably due to their shifts from isoosmolality and chemical neutrality. Specially puzzling was the harmful local effect of the otherwise well tolerated intralipid.

[Hypertrophic pyloric stenosis. Review of 314 cases (author's transl)].

Three hundred fourteen patients with hypertrophic pyloric stenosis have been operated from 1969 to 1976. The different etiologies are discussed. Clinical and analytical data are evaluated. Radiology is employed in 99 per 100 of the cases with no complications. Medical treatment used is exposed clearly as well as the surgical procedure (Monereo's modification of the classical Fredet-Ramstedt technique). Postoperative results and complications such as vomiting, wound infection (4.4 per 100), eventration (0.6 per 100) and fatal outcome (0.6 per 100) are thouroughly detailed as well as the associated pathology.

[Choledochal cyst (author's transl)].

This paper reports six pediatric patients with congenital choledochal cyst. From the long-term follow-up results of the six patients authors conclude that primary excision of the choledochal cyst and Roux hepatic jejunostomy are the first choice treatment for this lesion. However, it may not be possible in all cases, and choledochocystoenterostomy would then be useful as a second choice.

[Ileocaecal valve incompetence. A new syndrome (author's transl)].

Out of series of 237 colonic aganglionisms (1965--1977) 32 cases (13%) showed a clincial, radiological and manometric syndrome of "incompetent ileocaecal valve". Symptoms were vomiting, constipation with bouts of diarrhea, incomplete intestinal obstruction and failure to thrive. Sixteen cases were under P-3 weight percentiles. Initial diagnosis were aganglionism (10 cases), hiatal hernia (4 cases) and N.E.C. (1 case). Seventeen patients were explored through an iliac incision in the first three months of life. Ileocaecal continence was minimal (less than 25 cm. of water pressure). Ilocaecoplication was performed and completed with internal sphincterectomy (10 cases), colostomy (1 case) and caecostomy (3 cases). This new syndrome has been experimentally studied, but its etiology remains obscure. It introduces a bad prognostic component in aganglionism. Ileocaecoplication, a very simple operation, can be a lifesaving procedure.

[Surgical approach of retroperitoneal neuroblastoma in infancy (author's transl)].

Rarely retroperitoneal neuroblastoma is a well localized, encapsulated tumor, like it my appear somewhere else, as in the pelvic floor or mediastinum. Even with the same histological findings they are different from de point of view of invasion. Therefore the surgical approach should be different in each case. This is our main conclusion after de study performed in 48 cases operated upon in the last 8 years. We have tried three kinds of operations. 1. The so called curative, total resections. Performing a surgical ablation of the tumor and the organs macroscopically involved, either prior or after radiotherapy or quimiotherapy. At any risk, even of life in the early postoperative period. This kind of surgery has been undertaken in 34 cases with an early mortality of 9. The main aim of this technique is to divide the tumor in two across the supraaortic line well below the renal vessels and up to the diaphragm. In 18 cases the homolateral kidney was resected with the suprarrenal gland. Spleen and pancreas in 5 cases, colon in 4, and the inferior vena cava in 3. The survivors over 2 years are 19 cases. 2. Paliative resection, taking out the main tumor only, has been achieved in 4 cases, with the highest mortality because postoperative hemorrhage. We believed is a dangerous procedure. None of these children survived more than one year. 3. Biopsy and surgical macroscopic diagnosis of invasion plus placing clips at their margin has been carried out in 12 occasions. This had naturally the best early postoperative but not in the long run, none survived more than 2 years. A second look up with resection was undertaken in 3 cases with mortality of one. Most surgeons are puzzled when dealing with retroperitoneal neuroblastoma and some how disappointed before undertaking a long, difficult and highly risk operation, but in many instances still is about the only hope they may have.
