[Digestive reconstruction using mechanical staplers after total gastrectomy].

From 1980 up to nowadays, after total gastrectomy for gastric cancer, the intestinal continuity was assured by oesophago-jejunostomy and oesophago-duodenoplasty using stapling devices. Two patients died for causes not related to the technique, and other two patients developed a stenosis of the oesophago-jejunostomy, which was easily managed by endoscopic dilatation. In one patient a partial dehiscence of the oesophago-jejuno-anastomosis was treated by total parenteral nutrition. The Authors have systematically adopted mechanical sutures after total gastrectomy. However, possible intraoperative accidents and complications should not be underestimated, although most of them may be due to the operator's inexperience or stapler misuse.

[Aneurysm of the popliteal artery: diagnostic and therapeutic considerations].

The authors settle the roles of the most recent diagnostic methodologies useful to frame the popliteal aneurysm pathology namely digital arteriography, N.M.R., and doppler-flowmetry. They emphasize, in an observed case, the adopted therapeutic criteria, that is basically interventional. The thinness of saphenous veins draws toward the employing of "Goretex".

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.

[Mesorectal resection in oncologic surgery].

A surgical technique to "en bloc" resect the mesorectum while performing an anterior resection is here described. The procedure aims at preserving those nerves whose injury is responsible for a series of neurological sequalae, which affect the patient's quality of life. Fifteen dissections were carried out in order to demonstrate the possibility to perform an accurate mesorectal lymphadenectomy while preserving, in most cases, the nervi erigentes and, in some cases, the hypogastric plexus.

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)
