Giant sigmoid diverticulum.

The case of a giant diverticulum of the sigmoid colon in a 74 year-old woman is reported. The diverticulum had perforated into the urinary bladder and required a 3-phase operation with resection of the sigmoid colon and urinary bladder. Giant diverticulum is considered a rare complication of diverticulosis. Generally, it is a pseudo-diverticulum that grows due to a valve mechanism working in the neck of the diverticulum. The differential diagnosis lies mainly between intestinal duplication and pneumatosis cystoides. Surgical therapy yields favorable results.

[Modified Gilbert's technique in the treatment of persistent inguino-scrotal hernias in aged patients].

In elderly males, and in particular in very old men, the anatomical changes produced by senility encourage the formation of large inguino-scrotal hernias. Their repair may be achieved using Gilbert's technique to which the authors have proposed a number of variants. The good results show that the "tension-free" technique may be correctly applied in elderly patients with inguino-scrotal hernias, thus allowing a straightforward postoperative recovery with no complications.

[Immunological variations after thymic stimulation with special reference to IL2-RS in patients operated for neoplasms].

The paper reports a study which was carried out to assess immunological function by assaying IL2 in cancer-operated patients treated with thymostimulin. The results of the study show that, used in normally fed, immunodepressed patients, this immunomodulator is able to normalise levels of lymphocyte subpopulations and to bring serum concentrations of IL2-RS to the levels of normoergic patients.

[Constipation: drug or surgical treatment?].

Constipation is a very frequent symptom. It affects 7-10% of people. Otherwise a severe constipation exists which is rare, but extremely serious with evacuations every 15 days to 2 months. We expose the classification of constipation in its types: colonic, rectal and anal. We analyse the diagnostic trial which has to be started with a careful anamnesis and well directed physical examination. Laboratory tests and instrumental investigations will be essential means to define exactly the type of constipation and its pathogenetic mechanism. We go deep into physical involvement of constipation and into the problem of constipation in the elderly: except for particular groups (women suffering from colonic hypokinetic constipation) the age of patient is usually old. Medical treatment is described especially regarding the type of constipation. At last we review the surgical techniques proposed for every form of constipation, with exposure and interpretation of their results.

[Economic amputations of the lower limbs due to ischemia. I].

The problem relating to leg amputation following ischemia are analysed in the first part of this study, bearing in mind that amputation must be as conservative as possible in order to ensure the best quality of life. Following a short review of the topic and the introduction of recent trends, the case for amputation, which must be early in order to be conservative, is studied. The first part of this article concludes with a discussion of Doppler and clinical evaluations as techniques used to determine the level of amputation.

[Economic amputations of the lower limbs due to ischemia. II].

In this second note, some technical details used during amputation are described, leaving out the systematic description of interventions. The analysis of the postoperative period shows that the more distal the amputation, the higher the incidence of local complication, while about postoperative mortality our data show an opposite trend. The Authors conclude by pointing out that an early indication and an accurate evaluation often allow a more distal amputation, that must be as conservative as possible anyway.

Biliary reflux after cholecystectomy: a prospective study.

The authors carried out a prospective study to ascertain whether cholecystectomy itself might be the cause of duodenogastric reflux. Patients with cholelithiasis were examined and underwent the following tests: hemanalysis, gastroscopy with biopsy, 24 hour pH-metry and acetaminophen test. Twelve patients were selected. Six months after the operation the tests were repeated. All patients were asymptomatic. Hemanalysis was normal in all 12 patients and no difference was seen in the tests of 5 of the patients; however in the other 7 differences were observed in all the tests. The authors conclude that cholecystectomy helps to provoke duodenogastric reflux in predisposed patients, and that this reflux may be asymptomatic.

[Relations between markers and immunological status in surgical patients. Tumor markers and immunity in surgery].

The correlation between the immunological status of surgical patients and cancer is examined. 52 patients with gastric and colonic cancer were studied. On the basis of the immunological results of skin tests these were subdivided into non-reactive and reactive. The two groups were statistically compared in relation to cancer stage and blood concentrations of 4 markers: CEA, Ca 19-9, Ca-50, T.A.T.I. The first data show that anergic patients are older to a statistically significant degree; the second that there are no significant differences between the two groups as regards cancer stage. The third data show a difference between the two groups in relation to two of the four markers; anergic patients have a statistically significant higher blood concentration of CEA and T.A.T.I. This is rather interesting, since the literature offers no specific studies on the correlation between the patient's immunological status and tumour marker concentration. Therefore, in clinical practice, the high concentrations of these markers, could reveal, as well as the presence of cancer an endangered immunologic status.

A study of esophageal reflux following total gastrectomy with hepatobiliary sequential scintigraphy using TC-99m DISIDA.

A new technique to study esophageal reflux by means of hepatobiliary photoscintigraphy using TC-99m DISIDA was examined. The study was undertaken on 19 patients undergoing total gastrectomy without esophageal recurrence or hepatic or pulmonary metastases. The results of hepatobiliary photoscintigraphy were compared with the clinical, endoscopic and radiologic data. From this comparison it was demonstrated that photoscintigraphy is a non-invasive procedure which permits the study of the intestinal loops excluded from the transit of food but not of bile. Hepatobiliary scintigraphy was shown to be a reliable examination and the only one which demonstrates the reflux under physiological conditions, since the 24h. pH test in the absence of the stomach does not clearly prove the presence of alkaline reflux (bile) in an alkaline environment (esophagus). The disadvantages of photoscintigraphy are that the reflux is demonstrated only during the period of examination and in the patients undergoing total gastrectomy it is difficult to identify with accuracy the esophageal anastomosis. In these cases however, the radioactive bolus was used to localize the anastomosis and therefore to assess the esophageal reflux.

Technique for inguinal hernia repair in the elderly patient.

A technique for the repair of inguinal hernias in elderly patients with weak abdominal muscles has been presented. It consists of the overlapping of the flaps of the aponeurosis of the external oblique muscle according to the method previously proposed by Andrews. To date, the technique has given good results, even in very old patients, with almost completely atrophied muscles.
