[Laparoscopic cholecystectomy in acute cholecystitis].

In a 18 month period 19 patients (4.7%) out of 400 affected by acute cholecystitis underwent laparoscopic cholecystectomy. In 18 cases the diagnosis was preoperative on clinical signs or ultrasound scan basis. Intraoperative and histologic confirm was obtained in all cases. Mean age was 44.9, 11 were males and 8 females. The procedure resulted longer and more difficult compared to the global series of the same period: 90 min. versus 56 min. respectively, with a difficulty score higher than 4 in 89% of cases versus 40% of the global series. Furthermore, in 56% of cases versus 23.3% of the global series an intraoperative contamination from gallbladder content was recorded. Nevertheless, only 1 (5%) minor complication was observed, in the form of omphalitis, which recovered in 2 days. Therefore, discharge was possible in average within 4 days, excluding the first two cases operated, respectively discharged in 5th and 7th p.o. day as a precautionary measure. Early coelioscopic cholecystectomy is safe and effective, if carried out by well trained surgeons, even in acute cholecystitis.

[Mini-invasive surgical treatment of gallstones and common bile duct calculi].

Between June 1st 1990 and December 31st 1991, 449 patients with cholelithiasis were operated on. All patients with isolated cholecystolithiasis (400) were offered video-laparoscopic (VLC) treatment. Forty-nine patients had both cholecystolithiasis and choledocholithiasis. They all underwent further evaluation by ERCP, on the basis of which 30 patients were selected for sequential endoscopic and laparoscopic treatment with endoscopic papillosphincterotomy (EPST) followed by VLC. Three patients were selected for VLC and ideal laparoscopic choledocholithotomy. No complications were observed. At present, sequential ERCP-PST and VLC treatment seems to be the ideal approach to combined cholecystic and choledochal lithiasis in terms of safety, efficacy and tolerability. The increasing surgical skill in the field of minimally invasive surgery and the availability of sophisticated laparoscopic instrumentation allow to consider VLC and laparoscopic choledocholithotomy a valid alternative in terms of reduced surgical trauma and patient discomfort.

[Surgical staplers in colorectal surgery: 10 years of experience].

The Authors dissert on some technical details for a correct use of staplers in colorectal surgery. Surgical skill and technology assure always better results, nevertheless the experience and knowledge of the single surgeon must be a guide for further research.

[Criteria of radicality in surgical therapy of rectal cancer].

The Authors discuss on their experience in radical rectal cancer surgery critically reviewing results of the current literature. In particular, the importance of distal clearance, abdominopelvic lymphadenectomy and total excision of the mesorectum is stressed. They conclude that radical surgery, if performed according to certain principles, can improve survival without affecting the incidence of major complications.

[Venous replacement surgery: history, update and perspectives].

The impulse given to vascular surgery by new technologies has facilitated the use of the bypass technique in a number of arterial pathologies with better and better results over time. At the moment, however, we haven't a "sure prosthesis" in venous surgery. Our intention has been to examine the most significant developments, studying all the available material dating from the beginnings of the art up to the present. After a careful examination of the venous pathophysiology as well as the most valid surgical approaches, we tried to evaluate on laboratory animals the results of experimental graft replacement of the inferior vena cava. In this study we analysed prostheses in PTFE, biological prostheses, spiral composite vein grafts, arterial autologous grafts. For the experimental study we used 55 rabbits (New Zealand and Fiandra). Results have been rather successful with respect to biological prostheses (62.5% patency) and PTFE (66.6%). As for spiral composite vein graft prosthesis patency over time was very low (16.6%); this was affected by the different venous graft (heterologous graft) and caval wall thicknesses. Arterial autologous graft was carried out only once because rabbit experimented on did not stand up to surgical stress.

Techniques of rectal oncologic survey.

The possibility of constructing very low anastomoses using stapling devices led many surgeons to reduce the length of the distal clearance to 1-2 cm. This made it possible to perform a low anterior resection instead of an abdominoperineal resection of the rectum in a greater number of cases. Furthermore, the enthusiasm in preserving sphincteric function induced some Authors to perform a local excision for tumors of the distal portion of the rectum. On the other hand, in order to improve patients' survival after curative operations for cancer, either of the rectum or rectosigmoid junction, other surgeons have adopted a more aggressive approach, extending exeresis to the peri-aortocaval and pelvic nodes, and to the possible liver metastases as well. On the basis of our experience (374 cases from 1972 to March 1989) and a critical review of the literature, indications, techniques, and results of curative operations for both rectal and recto-sigmoid junction cancer are examined. The role of extended abdomino-pelvic lymphadenectomy is also discussed. The Authors believe that in the absence of a reliable evaluation of the potential of these tumors, an aggressive approach is required. Local excision is reserved to very selected cases, which should undergo an intensive follow-up in order to detect recurrences at a very early stage.

Stapled sutures in digestive tract surgery.

A six-year experience with mechanical sutures in digestive tract surgery is reported. Forty-nine esophageal resections during azygo-portal disconnection were performed since 1979 up to June 1986. Four patients died in the early postoperative course with no evidence of suture-related complication. One patient developed an anastomotic stricture (2.2%), which was successfully dilated. Fifty-three total gastrectomies with stapled reconstruction were performed between 1980 and June 1986. Two patients died soon after surgery for reasons unrelated to the suturing technique. Two strictures of the esophagojejunal anastomosis (3.9%) occurred two to three months after surgery and underwent successful dilation. One esophagojejunostomy (1.9%) leaked and one (1.9%) underwent uneventful remedial surgery (conversion of an omega-shaped loop to a Roux-en-Y procedure). Ten isoperistaltic jejunal interpositions, six Billroth I partial gastrectomies and 14 Roux-en-Y loops for hepatico- or pseudo-cystojejunostomy were performed since 1983 up to June 1986 in the absence of any operative morbidity or mortality. Twenty-three right colectomies were performed from 1983 to June 1986. The only complication reported was one leakage (4.3%) which spontaneously healed. Ninety-eight patients underwent formal colonic resections (anterior resection of the rectum, left hemicolectomy, subtotal and total colectomy) from 1981 to June 1986. Two patients (2%) died for reasons unrelated to the suturing technique. Three colorectal anastomoses (3%) developed a leak, one of which required surgical revision. One stricture (1%) was recorded in a recurrence-free patient three months after surgery. One patient (1%) complained of minor rectal bleeding. Two patients (2%) developed small anal fissures due to forced passage of the instrument.(ABSTRACT TRUNCATED AT 250 WORDS)
