From October 1995 through March 1997, we performed 30 microsurgical reconstructions and achieved microvascular anastomoses in 16 with an automatic stapler (VCS) which allows insertion of titanium clips in the everted vessel walls. The mean age of the patients (15 men, 1 woman) was 42 years. Mean vessel diameter of the donor and recipient sites was 2 mm for the arteries and 3 mm for the veins. Recipient vessels had suffered radiation damage in 3 cases. Micro-anastomoses were performed in 26 cases, with end-to-end sutures in 24 and end-to side sutures in 2. There were 11 arterial procedures including 3 bypasses and 15 venous procedures with 1 bypass. Peroperative thrombosis occurred in 2 cases and were treated by undoing the anastomoses and resuturing manually. There were no early or late postoperative vascular complications. This clinical experience confirms the advantages of this mechanical approach to microanastomotic procedures for small vessels as previously demonstrated in experimental work: a system avoiding transfixation, rapid procedure, reliability.

Gravity of abdominal vessels traumatisms is secondary to multiple factors. It depends on the type of injured vessels, aetiology and associated lesions. Between September 1984 and March 1995, 22 abdominal vessel traumatisms in 16 patients (mean age: 39 years) were treated. At surgical exploration, 4 aortic and 2 renal vein lesions, 7 iliac artery and 3 renal artery contusions, 2 superior mesenteric artery dissections; 3 infra-renal vena cava ruptures and 1 superior mesenteric vein dilaceration were found. All lesions were caused by penetrant wounds secondary to firearm or blade injury or secondary to injuries due to ski or traffic accidents. In 5 cases, lesions were iatrogenic. There was no mortality in the post-operative period, 14 patients out of the 16 patients operated on have been followed during a period from 1 to 120 months.

The lifelong risk of overwhelming infection after splenectomy is well recognized. Although children are at greater risk, adults are clearly vulnerable. This is an incentive to safely preserve the spleen in splenic injuries. Nonoperative management and use of different surgical techniques and synthetic materials to stop bleeding have been experienced and reported. They have the major advantage of spleen mass preservation and prevention of splenectomy complications: but also some disadvantages, for instance: prolonged hospital stay and subdiaphragmatic collection or delayed spleen rupture. This has prompted us for splenic salvation without any attempt to stop bleeding by transposition of spleen into an extraperitoneal cavity created surgically. During a 4 year period (from the end of 1989 to the fall of 1993) ten trauma patients were treated with this original technique. All of these patients had a definitive indication for emergency laparotomy. The procedure was successful in all patients without any unexpected complication.

Many regional anesthetic techniques can be used in the setting of abdominal surgery. Spinal anesthesia has limited indications for lower abdominal surgery (below T10), especially abdominal wall surgery and anal surgery. Indications of epidural anesthesia are quite similar, while epidural analgesia can be extensively used for postoperative analgesia, provided great attention is paid to strict monitoring and safety rules. Finally, peripheral regional anesthetic techniques are discussed, highlighting their advantages in this particular setting.

Morbidity, absention and duration of cares are important factors for the treatment of groin hernias. Deep and tension free cure is a key element to decrease the rate of recurrence. Utilization of prosthesis cannot provide a rate of 100%. This must be taken into consideration for indications. Beside we must take into account specific risks of each technique. Hernia treatment cannot be unique. This parietal surgery must remain a technique with low morbidity. As for treatment of unilateral hernia, we have qualified a technique of hernioplastia depending upon theses criteria, by inguinal incision, without prosthesis. Our technique includes: A complete dissection of the inguinal canal. The resection of the sac of the hernia at the internal ring. A deep cure of the fascia transversalis. A systematic incision of discharge on the anterior face of the rectus sheath. This incision is extremely internal and constitutes a large musculo-aponeurotic flap of 8 to 12 cm that makes this cure tension free possible. In the term of 10 years, our recurrence rate is below 1% for type I or II hernias in Nyhus classification. Consequently we discuss the indications for prosthesis. They must be reserved for hernias with high recurrence risk, bilateral hernias of for recurrent hernias.

Carotid artery reconstruction (CAR) may be achieved through a variety of techniques. The method of choice is based upon the patient's symptoms, the diffusion of the atheromatous lesion in the internal carotid artery and the experience of the surgical team that usually deals with these patients. Between January 1987 and May 1995, we performed 185 CAR using saphenous vein graft. The indication for surgery was atherosclerotic occlusive desease in all patients, sixty-two per cent of whom were asymptomatic. In the early postoperative period one patient died of aspiration, two patients suffered a stroke (one major and one minor) and five patients had a transcient ischemic attack due to carotid clamping intolerance. Two late restenosis and two graft occlusions occurred. The cumulative operative morbidity and mortality rate was 1.6%. This series demonstrates than venous grafting for carotid reconstruction yields satisfactory short- and long-term results and is a valuable alternative to endarteriectomy. Follow-up by Duplex-scan revealed no evidence of morphological degradation of the vein grafts.

Thirty one cases of failed antireflux surgery were analyzed. The first operation had been performed on 24 patients with uncomplicated reflux and 7 patients with complicated reflux. There was an abnormality of the cardia in all cases. Twenty eight patients had been operated through an abdominal approach and 3 through a thoracic approach. The failure was diagnosed during the first year in 12 patients. The reflux became complicated in 17 cases. Oesophageal stenosis was the most common complication. Twenty four patients were reoperated through an abdominal approach and 7 through a thoracic approach. In 29 cases out of 31, an anatomical cause of the failure was found and rectified. Mortality was nil. The results of iterative surgery were good in 80 p. cent of cases after a mean follow up of 6 years.
