In 16 patients affected by cancer of the mild or lower 3 of the rectum, has been performed a colorectal anastomosis by EEA Stapler, with abdomino-transanal approach. In the postoperative period no case of anastomotic bleeding or stenosis has been observed. 3 patients (18%) presented minor anastomotic dehiscence detected by radiologic examination, without clinical symptomatology. The EEA Stapler anastomosis seem sure almost as the traditional hand sutures, and allow the execution of anterior resection instead of abdominal perineal amputation of rectum.

The aim of the study is to find an eventual correlation between the presence of Er receptors and epidemiologic (age, domestic anamnesis, weight, menarca) and clinicist factors (cancerous diameter, linfonodes, first symptoms). The presence of receptors is very important for the start of endocrine therapy. In conclusion we can affirm the absence of correlation between the presence of receptors and the factors we considered. The only exception is about the age of patients; very probably because too little number of patients was considered. On the contrary a correlation was observed between receptors and severity of cancerous receptors in neoplastic tissues was obtained with Poffanelli method using an Ultra-Turrax homogenization followed by a centrifugation at 3800 rpm; the separation was achieved with carbon-dextran.

The use of inert plastic (Prolene mesh, 0,027 inches in thickness fournited by Ethicon) as preperitoneal prosthesis in repair of incisional hernias and inguinal hernia recurrencies has been investigated in 28 patients operated upon then 1977 to 1984. In 9 patients the inguinal approach was used with one recurrence (11%). In 9 patients the posterior approach through a midline incision has been used with two recurrences (22%). In 10 patients with incisional hernias there was only one recurrence (10%). Total recurrences rate was 14%. Most recurrences occur in patients operated from 1977 to 1980 (40%). Patients operated in the last period from 1980 to 1984 had no recurrences.

Previous research has shown that MVO (Maximum Venous Outflow), VR (Venous Reflux), VE (Venous Emptying) and the respiratory waves recording are useful in differentiating occlusion and recanalization in postphlebitic syndrome. In the present work strain-gauge plethysmography was employed to quantitate the venous function after deep venous thrombosis of the legs. The studies were performed in a vascular laboratory with controlled temperature (23 to 25 C); records were obtained by a plethysmograph Parks mod. 270 connected to a Hewlett-Packard multi-channel mod. 7700. 17 patients (12 males, 5 females), mean age 55 years (range 24-75) that presented femoropopliteal thrombophlebitis documented by phlebography at the admission to the hospital were examined. MVO with and without superficial veins occlusion was measured by a mercury in silastic strain-gauge placed circumferentially about the calf. A pneumatic cuff thigh was inflated to 60 mm Hg. VE was measured in patients lying in inclined bed with the lower extremities 100 cm below the heart level compressing the calf with a pneumatic cuff 10 times for 5 seconds; the strain-gauge was placed on the foot level. VR after Valsalva's maneuver and the respiratory waves were recorded by a strain-gauge positioned at the maximum girth about the calf in patients lying on inclinated bed with the lower extremities 50 cm below the heart level. The result are here indicated: (Table: see text) There was differences in the evolution of venous function after deep venous thrombosis of the legs for each patient. Strain-gauge plethysmography may become evaluable non invasive technique in the evaluation of deep venous thrombosis evolution in the legs. The therapeutic assessment of postphlebitic syndrome.

10 esophagojejunostomies by EEA Stapler were performed on adult patients (8 males and 2 females, mean age 54 years), after total gastrectomy for gastric cancer. No postoperative bleeding or stricture were observed. 2 anastomotic leaks occurred (20%). The major cause of anastomotic failure is probably technical (incorrect assembly or lubrication of the instrument). According to the our experience and to literary data, the use of stapling devices for performance of esophagojejunostomies is recommended.

In 4 patients who under went low anterior resection for cancer of mid and lower 1/3 of the rectum, with colo-rectal anastomosis by posterior transphinteric approach, anorectal pressure profiles have been studied by open tip technique 30 d. 6 months following operation. Bowel movements, gas and feces discrimination and anal continence were also controlled. Resting pressure, delta % pressure changes during recto-anal reflex, pressure in voluntary contraction, altered in the first post-operative period, become normal in 6 months. Although volume and pressure at urgent rectal sensation, volume and rectal sensation and compliance altered after surgery did not change after 6 months, suggesting that the reservoir function of the rectum is lost, patients achieved a good control of bowel movements, and a good gas and feces discrimination and anal continence within the first 6 months of operation.
