[Medullar breast cancer, occult papillary carcinoma, pulmonary metastases: a case report].

The authors have carried out their study on a woman who previously underwent QU.A.R.T. because of a medullar breast cancer. She also had pulmonary metastases resistant to chemotherapy which were then resected by mini-invasive video-assisted thoracic surgery: it was so discovered that such lesions came from an occult papillary carcinoma of the thyroid gland originated in a multinodular goitre. This study has allowed the accomplishment of a right aetiologic and therapeutic classification of the patient.

[Vascularization of the gastric stump tubule in esophagogastroplasty (EGP)].

The authors present the results of the vascular supply of tubulized gastric stump in patients who had sub-total oesophagectomy and cervical oesophago-gastroplasty (OGP) for oesophageal carcinoma, evaluating the importance of altered tubulized gastric stump's vascular supply on oesophago-gastric anastomosis efficiency. From April 1989 up today 51 patients who had OGP entered this study. Among these 2 had intestinal reconstruction by whole stomach and 49 by tubulized gastric stump. These 49 patients had celiac and upper mesenteric arterial angiography 30 days after surgery. As regards vascular patency angiography allowed us to divide the tubulized gastric stump into three parts; giving useful information above all on the distal part of the stump, considered "at risk" as concerning vascular supply. The authors thus demonstrate that the anastomosis high rate dehiscence is preferably due to the oesophageal stump vascular supply (strongly affected by cervical dissection) rather than to the poor vascular supply of the distal third of the transposed tubulized gastric stump.

Angiovideo-assisted hemodynamic correction of varicose veins.

OBJECTIVE: Evaluation of the feasibility and utility of angioscopy in the hemodynamic correction (French acronyms is CHIVA) of primary varicose veins disease. EXPERIMENTAL DESIGN: Prospective evaluation of 25 patients, undergoing hemodynamic correction of primary varicose disease with intraoperative videoangioscopic guide. Patients have been selected according to criteria emerged from a prospective study that we had previously conducted. Follow-up lasted 1 year (range 8-18 months). SETTING: Department of Surgery, University of Ferrara, Italy. Institutional practice. One-day surgery. PATIENTS: Their selection has been carried out in our Vascular Laboratory. The adopted clinical criteria of selection were: Primary varicose disease of the long saphenous vein territory, no previous thrombophlebitis and/or sclerotherapy. Doppler cw and Duplex criteria followed were: competent deep venous system, long saphenous vein diameter minor than 10 mm and incompetent perforating veins diameter minor than 4 mm. INTERVENTIONS: 25 hemodynamic corrections according to the CHIVA method described by Franceschi. An angioscope, introduced through a distal collateral of the long saphenous vein, permitted the precise interruption of the venous-venous shunts and of the superficial venous system, just below the perforators chosen as re-entry points in the deep venous system. MEASURES: Clinical: varices and symptomatology reduction. Duplex and Doppler cw: detection of the superficial blood flow re-entry, in the deep venous system, through the perforators and identification of recurrences or new refluxes. Pre and postoperative Ambulatory Venous Pressure and Refilling Time have also been measured. RESULTS: In 20 patients symptoms and varices relief were recorded (80%), in 5 patients varices reduction was observed only during walking (20%). In 2 of these latter patients there was no re-entry through the perforators, with a recurrent sapheno-femoral reflux in 1 of them. Early complications recorded were: 2 long saphenous vein thrombosis (8%); 7 ecchimosis (28%) when heparine/saline solution had been used for angioscopic clearance. CONCLUSIONS: Intraoperative angioscopy is feasible and useful when the hemodynamic situation is complex and the Duplex map is difficult to be interpreted by the surgeon. In this series the second look percentage rate has been minor compared to the percentage rates published so far by other authors.

[The role of surgery in the management of diffuse (N3) lung cancer].

The aim of the paper is to give a contribution to the understanding of the role of surgery in patients with N3 lung cancer. The A. describe their results on 32 patients with N3 lung cancer operated on mediastinectomy; histological examination of the specimens showed 27 squamous cell carcinomas and 5 adenocarcinomas. The operation was performed through a median sternotomy to gain access to the left and right paratracheal nodes, pretracheal, precarinal and subcarinal nodes, subaortic and left and right hilar nodes that were removed together with the fat of the mediastinum. Left pneumonectomy was performed in 5 patients. There was no operative mortality; 12 patients were irradiated in the postoperative period with 5,000 Rads (50 Gy), while 18 or the 27 patients with squamous cell carcinoma are still alive.

[Tracheal sleeve lobectomy in the radical surgery for lung cancer].

Tracheal sleeve lobectomy is right upper lobectomy extended to include resection of the main bronchus, the carina and a segment of the trachea with end-to-end anastomosi of the trachea and end-to-side anstomosis of the intermediate bronchus on the main left bronchus, or the upper lobe on the trachea. This operation is possible with the aid of high frequency jet ventilation. The surgical indication of this operation is bronchoscopic and functional and guarantees a good oncological radicality in the presence of N0.

Chilaiditi's syndrome as a surgical and nonsurgical problem.

Hepatodiaphragmatic interposition of the intestine is a rare anomaly (0.025 to 0.28 percent of the general population) described by Chilaiditi in 1911 and often believed to be of irrelevant clinical interest. To the contrary, recent studies stated that this syndrome is a potential source of abdominal problems requiring emergency or elective operation. From a retrospective analysis of records since 1976, four instances of Chilaiditi's syndrome have been found (three males and one female). Interposition of the proximal transverse colon was found in three patients and the small intestine in one patient. The findings of plain roentgenograms of the chest were determinants for diagnosis in three patients. In one patient, a barium meal was given to obtain a better definition. Two patients were admitted for malignant neoplasms (metastatic carcinoma of the breast, carcinoma of the gastrointestinal tract and cirrhosis of the liver) and died within a few months. The other two patients complained of abdominal pain. Patient No. 4 had gastric volvulus. Chilaiditi's syndrome was diagnosed intraoperatively in that patient and a surgical treatment with hepatopexy was performed, by suturing the falciform, the coronaria ligament and the anterior margin of the liver to the diaphragm with interrupted absorbable stitches. After a two year follow-up evaluation, this patient is as well as the patient who underwent medical therapy. Volvulus of the stomach, as was found in Patient No. 4, is an unusual condition and, to our knowledge, the patient is the second reported instance.

[An aneurysm of the extracranial carotid. A report of an interesting clinical case].

One case of extracranial carotid artery aneurysm observed is reported. This uncommon and interesting vascular disorder is still under discussion even if the present tendency is to treat it actively by reconstructive surgical procedures that make it possible to avoid the natural aneurysm complications with a low risk of postoperative neurological lesions.

A prospective study of local recurrence after resection and low stapled anastomosis in 183 patients with rectal cancer.

Local recurrence is the most serious complication of anterior resection for rectal cancer, usually occurring during the first two years after surgery. Over a five-year period, from 1981 to 1986, 183 patients underwent anterior resection for rectal carcinoma at the Surgery Ward of the University of Ferrara. Patients were followed for two years postoperatively. All operations were performed with staplers and classified according to Dukes, with 43 cases of Dukes' A; 83 cases of Dukes' B; and 57 cases of Dukes' C. In the first 24 months after surgery, the tumor recurred locally in 44 of the 183 patients (24 percent). Dukes' stage, grading distal resection margin, and histopathologic differentiation of the distal rectal ring left in the stapler after anastomosis were assessed to determine a prognostic indicator for the recurrence of the tumor. The stage:recurrence ratio was as follows: A, 1 (2 percent); B, 21 (25 percent); and C, 22 (39 percent). The grading:recurrence ratio was: G1, 13:51 (25 percent); G2, 24:110 (22 percent); and G3, 7:22 (32 percent). The ratio between distal rectal resection margin and recurrence was: 0 to 2 cm, 15:27 (56 percent); 2 to 4 cm, 16:74 (22 percent); and over 4 cm, 13:82 (15 percent). Histopathologic examination of the distal rectal ring was negative for all patients. These data confirm the direct relationship between class and local recurrence and indicate histologic grade and distal resection margin as significant prognostic parameters only when interpreted in the light of staging.

[Hemocholecyst: a rare cause of hemoperitoneum].

A rare case of haemoperitoneum due to gallbladder rupture with intraluminal bleeding is reported. The importance of a coagulopathy in the etiology of the disease is pointed out: in the present case it was related to cirrhosis and anticoagulant treatment during dialysis sessions.

[Comparative scintigraphic functional study of 3 different reconstruction technics following total gastrectomy].

Esophago-jejunal reconstruction, after total gastrectomy, is best performed by one of the following three operations: interposed jejunal loop, Roux-en-Y loop and "omega" loop with Braun anastomosis. To assess the effects of the three mentioned techniques three groups of 15 patients each were examined after total gastrectomy for I, II or III stage cancer. Four to ten months after surgery all patients underwent the following tests: a) esophago-jejunal transit with labeled solid meal; b) cholangio-scintigraphy and c) absorption test of biliary acids. A group of 10 patients, without gastrointestinal pathology, was selected for comparison. The data obtained from the comparative study, in agreement with the opinions held by many Authors and our previous research, demonstrate that the interposition of jejunal loop (Mouchet) is the reconstructive technique closest to the unoperated stomach and, for this reason, is to be preferred after total gastrectomy.

[Effects of therapy with aminaftone on chronic venous and lymphatic stasis].

Following a short introduction on the physiopathology of the phlebo-lymphatic system, the results of a study carried out on 114 patients suffering from chronic venous insufficiency (CVI) treated at the Department of General Clinical Surgery and Surgical Therapy of the University of Ferrara are reported. These patients were subdivided into two random groups and treated with common phlebotonic drugs and aminaftone, respectively. Both groups were also subjected to those physical and medical measures that are usually adopted for the treatment of such patients. The therapeutic effects were assessed by comparing symptomatology before and after 90 days of treatment, both subjectively (patient's assessment of the symptoms by means of a scoring system) and with objective methods (measurements and echo-Doppler examinations). The differences between the two groups were statistically very significant in favour of patients who had taken aminaftone. Excellent results were obtained in the treatment of CVI as well as in lymphatic-related pathology (lymphedema).
