[Acute pancreatitis: retrospective study on the treatment of 45 cases observed in a general surgery department].

The Authors have developed a retrospective study of 45 patients, suffering from acute pancreatitis and hospitalized at a general surgery Departement during a period of two years. The purpose of the study was to evaluate the validity of the classification of acute pancreatitis in three degrees (slight, moderate, serious), suggested by Hollender to prognostic and therapeutic aims.

[Liver lesions in abdominal traumatology].

Hepatic traumas are one of the most common sequelae of abdominal injuries. The Authors report 24 cases of hepatic traumas about a casuistry of 104 patients, that, in the decade '74-'84, had an abdominal traumatism. The quality of injuries, the therapeutic actions, and results are described.

[Open and closed injuries of the abdomen (review of 107 surgically treated cases)].

The authors relate about 107 cases of multiple injuries observed from 1975 to 1984. The causes of trauma, the different injuries caused by trauma, the association of different injuries intra and extra abdominal are examined; the diagnostic procedure, the results obtained, mortality, complications. The studied patients are divided on the basis of the trauma occurred. These data support the position that, in patients with severe multiple injuries, certain criteria, as rapidly increasing abdominal distension or uncorrectable hypotension and isolated rigidity of abdominal wall, eliminate the need for diagnostic examinations and make these procedures unwise waste of valuable time.

[Evaluation of the sphincter function and rectal sensitivity in rectal prolapse associated with fecal incontinence].

It has been suggested that incontinent patients with rectal prolapse develop a relaxation of the internal sphincter at a lower filling volume than those with the same disorder who were continent. A constant relaxation of the internal sphincter during filling before the individual experiences a need to defecate could be a contributory cause of the incontinence in these patients. Aiming to evaluate the former observations we have investigated continent and incontinent patients, with complete and internal rectal prolapse, by mean of the recto-anal manovolumetry. 31 patients were studied, 21 had a complete rectal prolapse and 10 had internal rectal prolapse and 28 sex and age matched controls were selected among volunteers. No difference has been found between the continent and incontinent patients with rectal prolapse, in term of sensory function studied by graded isobaric distention. Moreover, no difference has been found between the rectal volume at which perception of filling and relaxation of the internal sphincter during filling occurs. Therefore, in this respect, the present data are not in agreement with the theory proposed.

[Occult rectal prolapse: functional results after rectopexy].

In the present work the Authors have studied 19 patients with occult rectal prolapse evaluating symptoms and functional results after posterior abdominal rectopexy. Symptoms of internal rectal procidentia appear as a definite syndrome. In our patients pain upon defecation, this being often localized to the perineal and sacral region, was observed in 14 on 19 cases, while fecal incontinence was present in 5 cases (29%) and rectal bleeding in 8 (44%). These compliances are relieved by the anatomical correction of the rectal intussusception, but the preexisting functional disorders in the mechanism of defecation appear to be unaffected by rectopexy. (Sensation of obstruction 11 cases (58%) preop. e 9 cases (53%) postop.).

[Variations in rectal capacity and compliance after abdominal rectopexy].

The aim of this study was to attempt to gain insight in to the pathophysiologic characteristics of rectal prolapse by evaluating rectal compliance in patients with complete or incomplete rectal prolapse, before and after rectopexy. 21 subjects with complete rectal prolapse and 10 subjects with internal procidentia of rectum were treated with one of two abdominal rectopexies, according to Wells or according to a modified Ripstein's technique. For comparison, measurements were also carried out in 17 age and sex control subjects who had no bowel disturbances or anal symptoms. On distension with 40 cm H2O rectal volume amounted to 218 (175-255) ml for controls, 225 (178-256) ml for complete prolapses and 200 (125-225) ml for invaginations. Compliance amounted respectively to 9.5 (5-11,4), 8.5 (5-12,6), 7.5 (4-10,6) ml/cm H2O in the pressure interval 0-10 cm H2O with a decrease in compliance at higher pressure intervals. There was no correlation between rectal volume and compliance and gas or faecal incontinence, evacuation difficulties, feeling of blockade upon defecation and constipation. The effect of rectopexy has been separately evaluated according to the diagnosis. In complete prolapse significant changes of rectal capacity were observed for lower distending pressures (from 10 to 30), but not for higher (40-50). The compliance was significantly different for even lower distending pressures (0-10 cm H2O). In internal rectal procidentia rectopexy did not significantly changed capacity compliance. This work confirms the observations that the rectal compliance in rectal prolapse, complete and incomplete, do not differ from healthy controls.(ABSTRACT TRUNCATED AT 250 WORDS)

[Continuous suture in laparotomy using an absorbable eyelet thread according to the Smead Jones technique].

In 78 patients undergoing laparotomy suturing was carried out using absorbable thread (polyglyconate - Maxon) with eyelet to obtain a continuous knot-free suture according to Smead Jones' technique. A prospective study was made of all surgical wounds three months after the operation to evaluate the reliability of this technique. On examination, wounds were fully healed in 98% of patients. Less than 2% of patients revealed infections, dehiscence or anomalous granulations of the wound. No laparocele were observed at the time of control using this method. Continuous suture using a trimethylene polyglyconate (Maxon) thread with eyelet according to the Smead Jones technique was found to be safe and effective. A follow-up after a longer interval will be performed in this group of patients in order to confirm these conclusions.

[Immunological problems in oncology (author's transl)].

The Authors, after a view of the problems of immunology, regarding the most recent discoveries, deal with the conclusions about the immunological reactions in research and clinical oncology. Many specific antibodies, formed as a result of the tumor, have been discovered in the field of research. It is impossible to say the same about human tumors and the probable hypothesis are numerous. The results until now obtained, even if they don't give a definite response, show that the immune defense of the organism has extreme importance for the beginning and the development of tumors, therefore further research could be a contribution to the cure of cancer.
