[Clinical features of 27 cases of ischemic colitis (author's transl)].

The Authors report own experience of ischemic colitis, related to 27 cases, that includes either primitive forms (transient ischemic colitis, ischemic stricture and necrotic-gangrenous ischemic colitis) or secondary (occlusive ischemic colitis, ischemic colitis following abdominoperineal excision of the rectum). Pathogenetic findings, now not completely defined, are discussed with reference to the literature on this subject. The important diagnostic problems are also evaluated, particularly in the evaluation of radiologic and endoscopic findings of spontaneous ischemic colitis; these, altogether, represent an almost specific clinical picture of ischemic colitis. At last are considered the problems related to surgical treatment, overall in the forms in which the irreversibility of the ischemic lesions has been ascertained.

[The treatment of acute cholecystitis (author's transl)].

Authors report own experience on 384 patients operated for acute cholecystitis, from 1970 to 1979, among over 2.100 operations for cholelithiasis performed in that period. Operations have been divided in 3 groups: 1) deferred after 2 months (196 cases); 2) deferred, but during hospitalization, between 8th and 25th day from the onset of acute symptomatology (133 cases); 3) early, within 72 degrees hour from beginning of the disease (55 cases). Many clinical features have been considered and among these bacteriological investigations. Diagnostic acids, especially echotomography in last years, surgical procedures, pathological findings and different rates of mortality and morbidity, for each group of patients, have been studied. The conclusion is that acute cholecystitis have to be operated early, not after degrees day from onset of symptoms, especially if there is no tendency to remission of symptomatology.

[Urodynamic evaluations after abdomino-perineal resection of the rectum (author's transl)].

An uro-dynamic evaluation has been performed on 25 patients, who had been submitted to abdomino-perineal amputation of the rectum and had thereafter shown functional disturbances of micturition. On the latter, causes and mechanisms are discussed, particularly neurological as well as mechanical and inflammatory ones, with regard to their relationship with sex and other possible aspects in the field of pathology. In 16 cases urinary retention developed, in 4 cases urinary incontinence, in 4 cases urgency but complete voiding. The authors conclude by stressing the role of pre-operative uro-dynamic assessment in every patient who is going to be submitted to rectal exeresis, in order to detect sub-clinical functional impairment of micturition, which could be suitably treated, during the main operation itself, by either desobstructive or reconstructive measures.

Intraoperative transcystic extraction of common bile duct stones by a Dormia-Pironneau catheter.

During cholecystectomy 21 patients were subjected to transcystic extraction of common bile duct stones by a Dormia-Pironneau catheter; this was the only treatment used for lithiasis of the common bile duct, in the absence of papillary lesions. Of these patients, 14 were followed up from one to three years after surgery. Clinical and radiological controls revealed the patients' complete recovery from the biliary disease. Our late results thus warrant the method. We suggest that is should be employed in all cases in which the presence of minute stones in the gallbladder, a wide cystic duct, and the absence of papillary lesions suggest migration of gallstones from the gallbladder to the common bile duct.

[Use of blood and blood derivatives in surgical patients].

In view of the considerable therapeutic significance of blood transfusion in connection with major surgery and of the various problems involved, the author offers a discussion of the best ways to use whole blood and blood derivatives in the surgical patient. First he gives a synthetic outline of the pathophysiology of blood losses; then he sketches a set of guidelines to appropriate remedial treatment; and last, he discusses the risks and drawbacks associated with blood transfusion.

[Hemobilia and hemoperitoneum (discussion of an unusual clinical case)].

A rare case of haemoperitoneum from rupture of haemocholecyst is described. The origin of the haemorrhage, on the basis of the case history, clinical, intra-operative and anatomo-pathological data, was in all probability intrahepatic. In addition to discussion of the incidence of this morbid event, the article refers to the most frequent causes of haemobilia, the physiopathological mechanisms supporting it, the symptomatological triad characterising it even when aspecific, and the available diagnostic possibilities.

[Observations on the immediate and remote results of 112 internal biliary drainage operations].

The Authors report on the indications and result of 112 operations of internal biliary drainage performed in two distinct periods. In the first period (1960-1968) direct operations on the papilla were preferred (30 cases) as compared with biliary-digestive anastomoses (10 cases). From 1969 to 1974 the two types of operation were roughly equivalent. An analysis of post-operative mortality, complications and long-term outcome in 80 patients observed indicates a lower risk, a smaller possibility of relapse and, on the whole, better stable results for biliary-digestive anastomosis as compared with direct operations on the papilla, thus justifying the increasing favour accorded to them in the second period considered. The indications for the two types of operation are also analysed and stated, with stress on the importance of accurate intraoperative diagnosis.

[Critical considerations on the use in instrumental divulsion of the papilla in surgery of the bile ducts. Long-term results in 103 cases].

With a view to carrying out a critical review of the use of instrumental divulsion in surgery of the bile ducts, a long-term follow-up was made, from one to 12 years after performance of this operation, in 103 out of 157 cases. An examination of the immediate results which were favourable, in contrast with those found at long-term, led to the conclusion that this procedure was of little use and it has now been dropped both in diagnostics and, with greater reson, in treatment of benign papillary stenosis.

[Bacteriological studies on the bile in different conditions of surgical interest].

A bacteriological study was carried out on bile taken, during the course of surgery, from 235 patients suffering from a wide variety of diseases, both benign and malignant, concerning the bile ways. The investigation, initially directed to the aerobic bile flora, was afterwards extended to include germs growing in strict anaerobiosis. The highest incidence of bactibilia was found in repeat operations for post-operative stenosis of the hepatocholedochus, followed by neoplasias of the gall-bladder or main bile duct, and calculosis of the gall-bladder. For germs growing in compulsory anaerobiosis the responses to the cultural test were all negative, while in two cases microaerophilic streptococci were isolated. Finally the results of the antibiograms made on the isolated microbial species are reported.
