[Laparoscopic cholecystectomy. Our experience].

This study analysed 90 cases of symptomatic cholelithiasis treated with laparoscopic cholecystectomy. 27% of the cases studied suffered from microlithiasis, 44% from multiple calculosis with calculi measuring 1 to 2 cm in diameter, 25% from single calculi measuring up to 4 cm in diameter, and 4% from a benign proliferative pathology of the cholecystic wall. Calculosis of the main biliary tract was also found in 3 patients and was treated by preoperative endoscopic papillosphincterotomy. In addition to routine tests and ultrasonography, endovenous cholangiography, or retrograde cholangiography (ERCP) in cases of suspected calculosis of the biliary tract, was always performed prior to surgery. Mean operating time was 60 min. Two procedures were converted into laparotomy due to laceration of the cystic artery. In one case laparotomy was performed on day two due to choleperitoneum following a lesion of the cystic duct. Pneumoperitoneum could not be performed in three cases. Mean hospital stay was 48 hours. No other intra- or postoperative complications were reported. These results support the opinion that laparoscopic cholecystectomy is a safe method, with few limitations and represents the treatment of choice in the therapy of symptomatic cholelithiasis.

[Video-thoracoscopic sympathectomy in the treatment of Raynaud's disease and palmar hyperhidrosis].

BACKGROUND AND AIM: Raynaud's syndrome is a clinical entity characterised by episodic vascular spasm, digital ischemia in response to cold or emotional stimuli and hyperhidrosis. Many patients suffering from Raynaud's syndrome are successfully treated using medical therapy alone. Those patients who do not respond to medical treatment undergo surgery but the indications continue to be a source of controversy. A modern approach to thoracic sympathectomy requires a video-assisted technique. The aim of this study is to attempt to use mini-invasive type surgery to treat Raynaud's disease and hyperhidrosis in order to evaluate the real efficacy of thoracic sympathectomy in a large number of patients. The results of this method were compared for the two different pathologies in question. METHODS: The methodology used by this study is based on instrumental and clinical tests performed before and after surgery on treated patients using a comparative criterion and with a minimum 5-year follow-up. The pre- and postoperative diagnostic tests were performed by the vascular surgery laboratory and using a C.W. Doppler and a reflected light photoplethysmograph. Capillaroscopy and laboratory evaluations relating to secondary Raynaud's disease were carried out by internist type structures. The patients enrolled in the study responded to the following criteria: primary Raynaud's disease, palmar hyperhidrosis and associated syndromes. The population came from a mixed sociodemographic background, albeit within a strictly regional zone (Sardinia). A total of 42 patients were studied. The surgical technique used consisted of the ablation of thoracic ganglia from the 2nd to the 4th. RESULTS: The results showed a resolution of symptoms in 95% of patients treated for hyperhidrosis, whereas a 50% recidivation rate was observed in patients with Raynaud's disease alone, although symptoms were less intense. The results for Raynaud's disease were more disappointing, but it is important to remember that surgery is the ultimate choice for cases with advanced lesions which do not respond to medical treatment. Under these circumstances, the possibility of halting the evolution of the pathology represents an auspicious achievement. CONCLUSIONS: The authors affirm that mini-invasive surgical treatment of hyperhidrosis was resolutive during a mean follow-up of 3 years. It therefore represents a valid method which causes minimum esthetic damage to the patient and the greatest functional benefit. The postoperative period is short (about 3 days) and free of major complications. There is virtually no post-surgical pain.

[Sutures without sutures in digestive surgery. Experimental study of the rat intestine].

The aim of the experimental study was to evaluate the possibility of performing an end-to-end anastomosis by using fibrin adhesive as the only means of suture. To this end, 24 Wistar rats were used, of which 16 underwent ilear resection and 8 underwent colotomy, and they were divided respectively into two groups. On the rats of the first group the anastomosis was performed by using only fibrin adhesive; on the rats of the second group operated the anastomosis was performed by using fibrin adhesive in association with non adsorbable suture material, while on those operated of colectomy the anastomosis was performed by fibrin adhesive and adsorbable suture material. The anatomo-phatological studies on the anastomosis have shown a similar healing process in the cases treated only with fibrin adhesive and by using absorbable material and has demonstrated the trange material from the suture, which are a possible causes of complication.
