In order to evaluate various protocols for the preservation of venous allografts 162 arterial reconstructions were performed in mongrel dogs bypassing their ligated femoral arteries. The cumulative 6-month patency-rates as determined by weekly palpation and regular angiography were. Group I = Synthetic grafts: (a) Dacron 48%, (b) PTFE 53%. Group II = Fresh venous grafts: (a) autografts 100%, (b) allografts 37%. Group III = Veins preserved in saline at 4 degrees C for 1 month: (a) autografts 44%, (b) allografts 34%. Group IV = Veins preserved in saline at -70 degrees C: (a) autografts 58%, (b) allografts 47%. Group V = Veins preserved in glutaraldehyde solution: (a) autografts 26%, (b) allografts 22%. Group VI = Veins preserved in Hanks-solution with 15% DMSO at -160 degrees C: (a) autografts 77%, (b) allografts 35%. Histological as well as immunological studies suggest that these results are determined by the preservation protocol in Groups III, IV and V and by the presence of rejection in Groups I and VI. As the results with the allografts are not superior to those obtained with synthetic grafts, their use should be confined to those cases where the use of synthetic materials should be avoided at any price. Further experiments with immunosuppression and antigenic matching are indicated to see whether this would improve the results obtained with viable venous allografts.

Anastomotic aneurysms of the femoral anastomosis after aortic bifurcation graft.

A 17 year experience (1958-1975 with anastomotic aneurysms of the femoral anastomosis after aortic bifurcation graft is presented. An anastomotic aneurysm is a progressive dilatation of an anastomosis between an artery and a prosthesis, caused either by a defective suture line or by a wall dilatation. One thousand one hundred and eighty-four femoral anastomoses with a decent follow-up were reviewed and 89 aneurysms were encountered, a per site incidence of 7.5%. Aetiological agents were arterial hypertension, non-infective bad wound healing, type of suture material, defect of the graft and trauma. The therapeutical approach with only 12% recurrences is a segmental interposition. The rate of satisfactory results was 78%. By reducing our bad wound healing from 15 to 10% of the anastomoses over the last five years, we reduced considerably our percentage of anastomotic aneurysms. The use of ultraleight weight prostheses seems to have also reduced the incidence and, in our study that we closed in December 1975, we encountered no aneurysm on Cooley or Milliknit, even with a follow-up of four years. Since the end of the study, however, we encountered one case of bilateral anastomotic aneurysm with Milliknit, one year after the primary operation but with a definite trauma in the anamnesis.

The management of abdominal wall stomata: skin protection, peristomal wound healing and support for the collecting bag. A multi-center study.

The specific properties of Stomahesive tested in 116 stomal and 20 fistulous patients render it really useful in stomatherapy where it increases the comfort of the patients: 1. it offers an excellent peristomal skin protection whatever the nature of the stoma or origin of the fistula; 2. it promotes rapid healing of skin lesions, even in ileostomy, transverse colostomy, ureterostomy and fistula patients; 3. it ensures an effective degree of impermeability; 4. it provides a large base for adhesion of the collecting bag; 5. it can be kept on for about 6 days in most cases; 6. The local tolerance is excellent (Acta chir. belg., 1977, 76, 533-537).

Chylothorax after blunt chest trauma.

An unusual patient with chylothorax following blunt chest trauma is presented. Diagnosis was, in this acute case, clear after thoracostomy. In our patient conservative therapy with total parenteral nutrition failed and he was cured with a surgical closure of the duct leak. Chylothorax can be the cause of important morbidity and mortality, and straightforward diagnosis and therapy are mandatory.

Repair of a high esophageal stenosis with a mucosal flap of a Zenker's diverticle.

A patient presented an esophageal stenosis due to lasertherapy by Dohlmann's technique for the treatment of a Zenker's diverticle. This esophageal stenosis has been repaired by taking a mucosal flap out of the Zenker's diverticle. The technique is presented in this paper, together with some analogue data from literature.

[Renal autotransplantation].

The progress of renal transplantation in the last 2 decades has made possible the development of autotransplantation and extracorporeal surgery of the kidney. By those techniques, it is possible to operate upon patients in which conservative conventional surgery is impossible. In this article the technique is described, and two typical cases are reported. The mean indications are renal vascular hypertension, malignant tumors of the kidney, traumatic lesions of the kidney and ureteral lesions. All these indications are described in detail.

Peritoneal lavage after abdominal trauma: indications, technique, results.

This study represents our experience with 1461 patients who were seen in the Emergency Room of the University Hospital in Ghent with multiple traumatic lesions, between 1978 and 1982. In 43% of these polytraumata, we did an explorative peritoneal lavage in order to obtain a quick evaluation of intrabdominal haemorrhage. In 65% of the patients, the lavage was negative; 221 positive lavages (35%) underwent abdominal exploration; in 85% of these there were evident positive findings. The remaining 15% showed either no lesions, or minor lesions not involving risk of life. The overall accuracy-rate of the technique described above is at least 93%.

[Analysis of severely injured patients admitted via an emergency service].

Data about the number and treatment of trauma-patients are, certainly in our country, very rare. In this study we showed that such a registration with grading of the severity of the injuries following the ISS-Score is feasible and useful. Further and more extensive registration seems necessary in order to obtain a better insight in epidemiology and treatment of trauma patients in our country.

[Treatment of intra-abdominal sepsis and necrotizing pancreatitis with staged lavage using a Zipper].

The mortality of generalised intra-abdominal sepsis and severe necrotising pancreatitis remains very high. The persistence of intra-abdominal septic foci leads to recurrent abscess formation, persistence of sepsis and development of multiple organ failure, ultimately leading to the death of the patient. Therefore we believe that a repeated and total elimination of all septic and necrotic material is the cornerstone of an adequate surgical therapy in these patients. We performed "staged lavage" with the aid of a Zipper in 24 patients (10 with intra-abdominal sepsis and 14 with severe necrotising pancreatitis). Via the Zipper 98 relaparotomies were performed (mean 4.1 per patient). The high Apache II-scores (12 to 45, mean 24) illustrate the severity of disease in most of these patients. The expected in-hospital mortality-rate was 59% while in our series 7 patients died on a total of 24 (28%).

[Long-term follow-up after Kaunitz repair of hiatal hernia].

Kaunitz-procedure for gastro-oesophageal reflux. Between May '74 and May '86 we performed 121 Kaunitz-procedures for gastro-oesophageal reflux, mostly with oesofagitis. Follow-up was obtained in 120 of these 121 patients. The mean follow-up is 55 months and the mean age 49.5 years at the time of operation. Of these patients 103 were completely free of reflux-symptoms after the operation while 6 patients had apparent amelioration of their symptoms. In 7 patients we obtained no subjective improvement but in 4 of them the oesofagitis, which they had preoperatively, has disappeared. 4 patients were reoperated because of anatomical recurrence. The results can be considered as good or excellent in 94% of the patients. The Kaunitz procedure is a simple and efficient operative technique in patients with hiatus hernia and reflux.

[Spleen-preserving surgery using a polyglactin (Vicryl) perisplenic prosthesis].

The use of a perisplenic prosthesis in Polyglactin (Vicryl) is a recent technique for spleen conservation after trauma. We present our experience in eight severely traumatised patients with hemoperitoneum on the basis of a ruptured spleen. In all cases we were able to save the spleen. No complications occurred and the splenic function was intact after the operation. An overview of the techniques for conservation of the spleen after trauma is given.

[Surgical case report: diagnosis of associated abdominal lesions in penetrating injuries of the lower chest].

We discuss the way to diagnose intra-abdominal lesions caused by penetrating objects in the lower thorax. Let us call these wounds penetrating wounds. Two kinds of penetrating wounds are considered: 1. shotwounds; 2. knifewounds. 1. In shotwounds of the lower thorax there is not any non-surgical method available to find the associated intra-abdominal lesions. In these cases the results of: 1. physical examination; 2. local wound exploration; 3. echography of the abdomen and 4. peritoneal lavage cannot be trusted. Only laparotomy can show us if any associated lesion in the abdomen exists. 2. For knifewounds we can make almost the same remarks: 1. physical examination; 2. local exploration of the lesion; 3. echography of the abdomen are not to be considered as good diagnostic tools to find the associated intra-abdominal wounds. However in this situation the results of peritoneal lavage are to be trusted. Without omitting a 24 h observation of the patient the most rational criteria for a positive peritoneal lavage are red blood cell greater than 100.000/mm3; white blood cell greater than 500/mm3.

[The McVay technic for inguinal hernia cure. Results of treatment in a teaching center (author's transl)].

Over a 20 year period 390 adults underwent 454 operations for inguinal hernia using the technique of McVay. The recurrence rate after primary repair was 7.61% and 18.33% for secondary hernias. This was usually early in the postoperative period. These results must be interpreted taking into a ccount that the operations were performed at a teaching institution.
