Aortic valve replacement with the minimal extracorporeal circulation (Jostra MECC System) versus standard cardiopulmonary bypass: a randomized prospective trial.

BACKGROUND: We prospectively evaluated a newly introduced minimal extracorporeal circulation system (Jostra MECC System; Jostra AG, Hirrlingen, Germany) for aortic valve surgery. METHOD: In a prospective, randomized study, 100 patients underwent aortic valve replacement either with standard cardiopulmonary bypass (n = 50, group B) or with the MECC System (n = 50, group B). The myocardial protection and the left vent were identical for the two groups. The intrapericardial suction device was never used (only the cell salvage device was used) to reduce the air-blood contact area. RESULTS: No significant differences were noted in patient characteristics and operative data between groups. Operative mortality (<30 days) was 2% for group A and 4% for group B (difference not significant). From the preoperative period to the postoperative period, the increase in C-reactive protein was significantly higher for group B (P <.001). The postoperative troponin I level was significantly lower in group A (mean 4.65 +/- 2.9 microg/L at 24 hours) than in group B (8.2 +/- 4.4 microg/L, P <.03). On the other hand, the MECC System was associated with platelet preservation. Renal function was better preserved and the neurologic event rate was significantly lower for the MECC group (P <.02). CONCLUSION: The MECC System is safe and allows aortic valve replacement under the most favorable conditions. The system is more biocompatible than standard cardiopulmonary bypass and provides a good postoperative biologic profile and good clinical results, particularly for high-risk patients.

[Adenocarcinoma of the anal glands].

The study aim was to report an adenocarcinoma of the anal glands revealed by an anal abscess in a 64-year-old man. Malignant transformation of an anal fistula is discussed in the genesis of this disease. Clinical symptoms are not specific. Abdomino-perineal resection of the rectum is the usual surgical treatment and adjuvant radiation therapy didn't prove its efficiency.

[Inflammatory pseudotumor of the spleen].

Inflammatory pseudotumor of the spleen is a very rare benign lesion of unknown etiology. Splenectomy is recommended to obtain histological diagnosis and to eliminate a malignant tumor.

[Papillary fibroelastoma. Report of 3 cases].

Papillary fibroelastoma is a rare, benign, primary cardiac tumour. The authors report three cases presenting with transient or full cerebrovascular accidents. The tumours were diagnosed during investigation by echocardiography, especially transoesophageal echocardiography. In view of the severity of symptoms and the high risk of recurrence, the patients were rapidly referred for surgery. In two cases, the tumour was located on the aortic valve at several sites. In one case, the tumour was single and implanted on the mitral valve. Surgery was successful with the pathology reports confirming complete ablation. The patients have not had any recurrence to date. The multiple nature of these tumours raises the questions of local spread, secondary degeneration of valvular nodes? The problem of possible recurrences is discussed.

[Place of super-selective vagotomy in the treatment of perforated duodenal ulcer].

Thirty-two duodenal ulcer perforations were treated by suture and supraselective vagotomy. Perioperative mortality was nil. The recurrence rate was 6.2% against 17% after elective supraselective vagotomy performed by the same surgeons during the same period. Results of this technique for treatment of perforated duodenal ulcer are compared with those of 28 simple sutures and 32 truncal vagotomies.

[Post-bulbary ulcers].

Authors report 121 cases of post bulbary ulcers between 1969 and 1987. They precise the frequency of complications in this localisations of the ulcerous disease: Hemorrhage: 38% Stenosis: 39.6% Peritonitis through perforation: 9.09% Anatomical reports of the post bulbary area explain the anatomo-pathological aspects made by the above mentioned complications added the biliodigestive fistula and perforations blocked of a surgical treatment. Considering these elements, the authors show the difficulty of a surgical treatment. They suggest choosing the most simple intervention: Treating the ulcer without approaching the ulceron area; namely; making truncal vagotomy and duodenoplasty, that of Finney being the most adapted in case of haemorrhage. On case of a stenosis, with gastric ditension, exclusion gastrectomy is the adequate intervention. The results are good, except two deaths that occurred by cataclysmic ulcerous haemorrhage.
