[Appendicitis: microbial interactions and new pathogens].

The Authors present an exhaustive review on microbial agents of appendicitis by means of literature and personal research data. Thus, a detailed analysis is made on common autochthonous agents and their pathogenetic interactions and on less common exogenous bacterial, viral, mycotic, protozoan and helminthic agents with emphasis to the role of Yersinia enterocolitica. In fact this bacterium seems responsible for 3% to 8% of cases in accordance with literature and personal research data (more detailed, Y. enterocolitica has been isolated in 3.8% of 208 inflamed appendices from both pediatric and adults surgical florentine patients). At the end, the pathogenetic role of "new" other bacteria, like Buttiauxella agrestis, Aeromonas hydrophila, Arizona, Streptococcus lactis, is debated on the basis of a personal study.

[Intrathoracic revascularization of the stomach in gastroplastic reconstruction of the esophagus].

Reconstruction of the thoracic esophagus after esophagectomy is usually achieved using the stomach which, after gastrolysis through an abdominal approach, is pulled into the right thoracic cavity and anastomosed to the esophagus. After gastrolysis by conventional methods, the blood supply of the stomach exclusively depends on the right gastric and epiploic arteries. In some cases, these arteries cannot ensure sufficient blood supply to the fundus of the stomach, which is at higher risks from a vascular point of view, since it depends on the intraparietal capillary anastomoses between the gastric branches on the left inferior gastric artery, the intraparietal rami of the short gastric arteries, which have been cut, and the parietal rami of the anterior cardiotuberous artery. When macroscopic signs of ischemic disorders of this area are observed intraoperatively, resection of the fundus of the stomach would considerably reduce the length of the organ that could be used for gastric esophagoplasty. To avoid this, we have been implementing an intrathoracic revascularization technique consisting in anastomosing the left gastric artery, either directly with the right internal mammary artery, or through a shunt with the saphenous vein between the subclavian artery and the left gastric artery itself. Finally, the intensification of the venous circle is performed by anastomosing the left gastric vein and the azygos vein. Details of the surgical technique, as well as the results obtained, are illustrated.

[Extensive lymphadenectomy in the therapy of cancer of the left colon and rectum: an analysis of the anatomicopathological data].

In the last 12 years in our surgical service, radical resection was performed in 142 patients with cancer of left colon and in 145 patients with rectal cancer. Extended lymphadenectomy was always realized: preaortocaval lymphadenectomy in colonic cancer; preartocaval and pelvic lymphadenectomy in rectal cancer. The incidence of C stage was 40.14% in cancer of left colon and 40.68% in rectal cancer. Neoplastic diffusion in preaortocaval lymph nodes was only in a patient with colonic cancer, never in patients with rectal cancer. The incidence of neoplastic diffusion in pelvic nodes was 3.12% (0 in superior rectum; 6.25% in medium rectum; 2.4% in inferior rectum). In 1 of 90 patients with tumour of medium or inferior rectum, we relieved tumoural involvement of pelvic nodes without neoplastic diffusion in regional nodes. These anatomo-pathological data subline: a) the low incidence of neoplastic diffusion in preaortocaval nodes in cancer of left colon and rectum; b) the importance of pelvic lymphadenectomy in cancer of medium and inferior rectum.

Ascending aorta to femoral arteries bypass without opening the abdominal cavity. Choice treatment in cases of complete occlusion of the infrarenal aorta.

In two cases which needed a revascularization of the inferior limbs, it was possible to utilize the subrenal aorta (the first case was affected by an infrarenal aortic occlusion; the second by an infection of a previously inserted aortofemoral graft), the AA. elected to perform a bypass with a dacron graft between the ascending aorta and femoral arteries according to the technique already proposed by Kaplitt. Having accomplished the proximal anastomoses to the ascending aorta through a midsternal incision, the graft was placed into a properitoneal tunnel down to both inguinal regions. This tunnel was obtained in the anterior abdominal wall by a blind blunt dissection entering the properitoneal space at the inferior end of the sternal incision. In this way the opening of the abdomen is avoided. On account of its poor risk, this procedure is advisable not only in cases of infrarenal aortic occlusion but almost in all aged and poor risk patients who require a revascularization of the inferior limbs.

Aneurysm of the gastroduodenal artery.

A case of aneurysm of the gastroduodenal artery associated with obstruction of celiac axis, is presented. The patient underwent successful surgical correction. The clinical and surgical aspects of this patient are discussed.
