[Carcinoma of the common bile duct].

The clinical courses of 18 patients with extrahepatic bile duct carcinoma operated on between 1960 and 1979 are reviewed retrospectively. The preoperative and intraoperative diagnostic difficulties due to marked peritumor sclerosis are pointed out. The location of the lesion appeared to bear the most important relationship to prognosis: the lesions located in the upper and middle thirds of the extrahepatic biliary system are often invasive of adjacent vascular structures and, hence, unresectable, necessitating a proximal biliary-enteric anastomosis or intubation to alleviate jaundice and pruritus. A more aggressive operative approach, however, will result in a higher survival rate, as shown in personal experience for lower third lesions resected by Whipple's procedure.

[Comparative analysis of manual and mechanical sutures in the surgery of neoplasms of the esophagus and the cardia].

The authors analyse 50 sutures by hand and 50 by stapling device in oesophagocardial surgery, and compare them as to time of performance, number and quality of complications and influence on the protraction of stay in hospital after operation. The conclusions indicate the sutures by device as the most reliable and safe, susceptible to supplant, although not totally, the techniques by hand.

[The surgical consequences of topographical variations of the implantation of the papilla in the duodenum].

The Authors underline the importance of anatomical variations concerning the location of the duodenal papilla. In roughly 75% of cases this structure pierces the duodenal mucosa at D2 and at the level of the lower flexure, in 20% at D3 and in about 6% at D1. Intraoperative cholangiography is most useful to spot the papilla, its position is fundamental from an anatomo-surgical point of view both when this structure is placed at a high level (when performing a gastro-duodenal resection), and when located at D3 level, if sphincterotomy is required. In this latter case the usual incision at 12 hours should be carried out at 9 hours instead in order to avoid surgical damage to the canal of Wirsung running vertically and along the common bile duct.

[Our experience in the preservation of the rectum in the surgical treatment of ulcerative rectocolitis].

The Authors report a personal series of 42 cases of Ulcerative colitis seen over a 12 year period. (1969-1980). These patients underwent total colectomy with preservation of the rectum. Intestinal canalization was restored by means of an ileo-rectal anastomosis performed either with colectomy or at a later stage. Results are satisfactory as an improvement of general conditions occurred. Normalization of the intestinal function was observed in 85% of cases. Rectal lesions, periodically kept under control with endoscopy and hystologic examination, improved noticeably. In a few cases a total recovery was attained with an adequate, postsurgical, topic therapy. No cancer onset in the rectal stump had been recorded thus far among these patients. In the light of the Author's experience, total colectomy with rectal preservation represents a sensible solution for the surgical treatment of Ulcerative colitis.

[Etiopathogenetic, diagnostic and clinical considerations on simultaneous bilateral carcinomas of the breast. II].

In the first note the Authors have described five cases of bilateral simultaneous breast carcinoma. Now they shortly describe some opinions about the problems of the genetic independence between the two diseases. They draw attention about the histologic diagnosis and the identification of diseases underestimated and now explained as carcinoma "in situ" potentially fit for transformation in infiltrating cancer. For this reason it's important and justifiable to have the patients with cancer of the breast, a series of clinical research as well as mammography thermography and biopsy of controlateral breast in order to ascertain the presence of carcinoma "in situ" that could justify the prophylactic mastectomy.

[A rare case of esophageal pathology: leiomyosarcoma (author's transl)].

The AA. report a clinical case of rare oesophageal pathology: the leioomyosarcoma sole case on 200 oesophageal neoplasms that they have observed. The clinical likeness with oesophageal carcinoma and the complete superimposition of reports that have been obtained in this case with instrumental examinations respect to the oesophageal carcinoma, didn't permit to do the diagnosis of histotype, while this diagnosis could be done only after the preparation of an histopathologic preparation. The patient who was operated on for superior polar esophago-gastrectomy, after 18 months is in good general conditions. THe AA. draw their conclusions after a short discussion. We must show in these paragraphs the particular macroscopic form of neoplasm that they have observed and the great difficulty of a diagnosis of leimyosarcoma without an histopathologic preparation. Agreeing with the most part of other Authors, they point out that the best therapy for these forms is surgical therapy.

[Association of idiopathic megaesophagus and carcinoma].

In the light of three cases of esophageal carcinoma developing on a pre-existing idiopathic megaesophagus the authors examine etiopatological, clinical and terapeutic problems related to this association. They believe that carcinoma of the esophagus tends to be a complication of cardiospasm in patients inadequately treated for the primary condition. Early diagnosis and an adequate Heller operation for cardiospasm will lessen the chance of cancer developing in megaesophagus with stasis. When finally diagnosed, this variety of esophageal carcinoma has an extremely poor prognosis. An even more important claim upon the clinician is to be alert to the hazards of continued stasis in megaesophagus and to devise earlier techniques of recognition, including more frequent recourse to biopsy during esophagoscopy.

[Traumatic hernias of the right hemidiaphragm].

Four cases of right traumatic diaphragmatic hernia are reported. The original aspect of this type of lesion is that herniation of abdominal viscera into the chest is usually delayed due to the liver temporary plugging of the diaphragmatic defect. Diagnostic importance of diaphragm elevation combined with mediastinal push-back is stressed, as well as the value of x-ray examination following pneumoperitoneum. Reduction of the hernia and repair of the diaphragmatic defect can easily be accomplished by abdominal route alone, instead by a transthoracic approach usually preferred by surgeons in delayed presentation, particularly in those patients with marked limitation of pulmonary reserve.
