Authors analyze some new knowledge in treatment of rectal and anal injuries proceeded from own clinical experience in comparison with studies of a range of foreign authors published recently. During last ten years together 24 injured patients with this diagnose were operated in Traumatological Hospital Brno, primary reconstruction was performed in 10 patients, secondary reconstruction after precise examination of pelvic fundus pathophysiology in 14 patients, mostly transferred from other clinics. Authors prefer primary treatment in 3 hours after injury. This opinion is supported by control examinations after performed reconstructions.

A new, five-grade classification of bile duct injuries associated with laparoscopic cholecystectomy, based on repeat operations carried out by the authors, is presented. Special attention was paid to the treatment of loss injuries involving the regions high above the level of the hepatic duct bifurcation. The procedures used in accordance with the classification system are described in selected cases.

Within a ten year period we have performed 433 radical operations on the rectum. An anterior resection of rectum was done in 110 cases, low anterior resection in 60 patients, very low anterior resection was done by stapler in 32 patients and was sewn by hand in 10 patients. Colo-anal anastomoses were performed 86 times and abdominoperineal amputation of rectum sec. Miles 20 times. Local transsphincteric procedures were used 14 times. In 12 patients the colo-anal anastomosis was performed either for recurrence of tumor or after a Hartmann's procedure. In the carcinoma of the lower half of the rectum there is still an unsolved question: whether to perform a low or a very deep low anastomosis or whether an extirpation of rectum with sparing the sphincters and sewing a colo-anal anastomosis is more beneficial. In the years 1980-1995 we treated surgically 64 patients with a tumor in anal area. All patient underwent preoperative radio- and chemotherapy. In our group adenocarcinoma was demonstrated in 6 patients, squamous carcinoma in 48 patients and squamous cells of the carcinoma in situ in 10 patients.

Authors analyze the group of patients surgically treated for rectal carcinoma during ten-years long period. While the surgical tactic in upper part of the rectum is solved by the resection with straight anastomosis, in carcinomas of lower part of the rectum there is an open question there, to use the deep pelvic anastomosis after radical resection or to perform the rectal extirpation with saving of sphincters and using the coloanal anastomosis. The necessary requirement is complex preoperative examination of the tumor and of pelvic fundus physiology. For application of coloanal anastomosis the rigid indications are determined. Authors used this method in 107 patients of the monitored group. Early and delayed complications of these interventions are analysed, indication for temporary stomy and application of pouchs. In the group of patients with coloanal anastomosis no local recurrence was noted, in the group with deep pelvic anastomosis the locoregional anastomosis was found in 8% of patients.

The authors analyze a group of 7 patients transferred to their hospital for instable fractures of the pelvic circle and lumbar spine. The pelvic compartment was manifested 24-48 hours after injury. Early diagnostics are based on the use of new imaging techniques, spiral CT examination is preferred, and angiography in stabilized patients. Early surgical intervention is aimed at evacuation of haematomas, revision of vessels, release of the ureters and temporary nephrostomy.

The authors inform on the increasing number of penetrating abdominal injuries during the last five years, especially in the criminal injuries. Diagnostic methods in a stabilised patient are analysed, diagnostic and therapeutic laparoscopy is preferred to lavage of the abdominal cavity in indicated cases. Urgent surgical revision is recommended in patients in a critical state on account of quickly increasing compartment syndrome, although staged laparotomy is needed. The timing of surgical methods is emphasised in serious associated injuries. Conclusions are illustrated with surgical results.

Nowadays the number of devastating injuries is increasing, as a consequence of traffic accidents and criminal incidents, too. Patients are often admitted in a critical state, the mortality rate in these cases is very high (50% and more). To decrease this high mortality, new treatment approaches must be chosen incl. the method called damage control. Knowledge of leading foreign centres are evaluated together with our clinical experience.

Defecography is used in the Czech Republic only exceptionally. Since 1988 the authors made 402 defecographic examinations. They submit a detailed description of hitherto assembled experience and their own modification of the examination. As contrast material they use at present Micropaque susp. thickened by means of wheat bran. They administer it by means of a modified press for dough preparation. The X-rays are taken on a modified ordinary stool made from soft timber. For screening of uncovered places in the visual field they use individually placed copper plates 2 mm thick. For better evaluation of the X-rays the authors place during examination an X-ray contrasting net behind the patient. Pictures are taken at rest, during contraction, during modified Valsalva's manoeuvre and during all stages of defecation. The authors mention the most interesting pathological pictures they encountered so far--internal prolapse, levator hernia, rectocele, sphincter defect, various forms of prolapses and dyskineses of the pelvic floor. In the authors opinion the basic quantifiable parameters are the magnitude of the anorectal angles. They used the assessment method described by Mahieu, as well as the mediorectal angle which in their opinion is a reflection of the patient's somatotype and levator function. More than the absolute values of the angles they emphasize the difference of the two angles and change of the latter during contraction and defecation. In their opinion enlargement of the difference during contraction and diminution to values close to zero is normal. Converse values are according to the authors evidence of dyssynergy of the pelvic floor. Independent assessment of the angles and magnitude of the lift of the pelvic floor by three subjects are subjected to statistical analysis. They provide evidence of complete reproducibility of results of anorectal angles according to the authors' definition. The results of assessment can be used to investigate relations with parameters of anorectal manometry (AM) or transrectal sonographyy (TRS) in subsequent investigations.

Authors analyze occurrence of injuries of external biliary tract relating to the increasing number of laparoscopic cholecystectomies, especially of loss injuries, very demanding for its reconstruction. The early diagnosis of these injuries is emphasized and the necessity of their surgical revision as soon as possible, best still during the primary intervention. Authors present the own reconstruction method by high intrahepatic anastomoses in loss injuries of the common hepaticus and its branches.

Authors evaluate clinical material of polytraumatized patients operated on account of liver injury during the last 15 years. The contribution of new imaging techniques is analyzed, especially of spiral computed tomography, for the diagnosis of liver injuries and associated injuries of the abdomen and retroperitoneum. These techniques enable in stabilized patients with the trauma I, II injuries and in some cases of grade III injuries to prefer conservative treatment. During the last 3 years the authors treated 5 polytraumatized patients with central liver rupture. Consistent with experience of major trauma centres in USA and Switzerland, criteria for conservative treatment are outlined, especially in patients of younger age groups.

Authors analyse the group of 22 operated patients admitted to the Spinal Centre of the Traumatological Hospital Brno for instable spinal fracture with the transversal lesion of the spinal cord, in whom the acutely affected abdomen and acute surgical disease manifested. The anamnestic and clinic examination of the abdomen is not reliable in patients with the transversal lesion of spinal cord for valid laws of the spinal cord. Authors evaluate the contribution of new diagnostic imaging techniques and endoscopic methods to determinate the early indication for surgical treatment.

During the ten-year period between 1982-1991 the authors operated in the Institute 12 casualties after perforation and avulsion of the gallbladder, 8 patients on account of injuries of the hepatocholedochus and 15 patients where after injury posttraumatic acute cholecystitis developed. The authors evaluate critically the asset of new diagnostic preoperative procedures for assessment of early indication of surgery. In the surgical tactics they prefer reconstruction procedures which prevent such serious postoperative complications as relapsing cholangitis or stricture with cholestatic affection of the liver [1,3].

Based on the complex evaluation of the continence by anorectal manometry, EMG examination of sphincters, transrectal sonography, defecography and Colonic Transit Time examination, the analysis of the group of 15 patients partially incontinent after operation of carcinoma of the lower part of the rectum has been done. In these patients the deep pelvic anastomosis or coloanal anastomosis was performed. In none of the patients any serious organic damage of sphincters was manifested, the causes were dominantly extrasphincteric and functional, solvable well by conservative methods.

Authors treat in their institution yearly 100-120 patients with polytrauma. In the Endoscopic Centre of the hospital approx. 20 gastroduodenal ulcers are diagnosed yearly in patients with supposed stress etiology. Authors analyze the pathophysiology of origin of stress ulcer, clinical symptoms and acute diagnostics. They evaluate results of early surgical treatment. Authors place the great importance on explicit treatment methods for prevention of stress ulcer origin.

Authors evaluate their experience in treatment of patients with polytrauma during last 10 years. They use the 5 level classification applicated particularly in German and Austrian traumatologic centres. Authors initiated in their workplace the computer assessment ISS - Injury Severity Score, Apache II -Acute Physiology and Chronic Health Evaluation II. The care for polytrauma requires the highly qualified individual approach and should be subordinated to threatening or developed complications. The question of timing of emergent operations in polytraumatized patients is solved that was one of research projects of this institution, too. The reconstructional operations are preferred with regard to retaining of function and life quality of patients. Key words: increasing number of polytraumas, classification, diagnostic and therapeutic methods, results.

Authors analyse a group of patients operated for colorectal carcinoma in their hospital during ten-years period 1982-1991. 421 patients were operated for ca recti, in more as 65% of cases the sphincter saving operation was preferred. The used method was elaborated by Hojo and Kaso from Japan. The contraindication of sphincter, and insufficiency of sphincter, objectively rectomanometrically detectable. The resection of urinary bladder was contemporary performed in 15 patients, the hysterectomy with adnexotomy in 8 patients, the vaginal resection in 5 cases and the resection of small intestine in 8 cases. The resection of os sacrum to S 3 was performed in 3 patients. The radical resection with establishment of the deep pelvic anastomosis is burdened by certain number of early and delayed complications, too. Authors analyse its causes, possible corrections, but also its prevention.

In the Traumatological Hospital Brno approx. 100 polytraumatised patients yearly are admitted with involvement of 2, 3 or 4 systems. During the period of years 1982-1991 authors operated 308 injured patients with increasing haemoperitoneum, 254 patients with profuse bleeding into retroperitoneum, 77 patients with traumatic perforative peritonitis and 61 patients with severe thoracoabdominal trauma. Mortality in this group was 26%. Authors evaluate the contribution of new diagnostic methods for the indication of early surgical treatment, and results of operations, complications and problems.

Thoracic trauma represents 12,8 % of all trauma patients treated in author's workplace. Mortality was 12,7 %. Authors evaluated the contribution of new diagnostic methods, in particular CT examination with contrast and sonography, to determinate the indication of the early surgical treatment. From 1992 in the framework of the grant project the early surgical treatment of instable thorax was performed in 29 patients with polytrauma and serious associated thoracoabdominal trauma by the own set prepared in cooperation with the firm Medin. Authors determined indications for thorax stabilization prudently, and stated contemporary contraindications of this treatment. They evaluated the therapeutic contribution of early stabilization of the thorax in patients with polytrauma. Key words: instable thorax, polytrauma, indication, results of stabilization.

Authors analyse the group of 17 patients operated for rectal and anal injury. In this group 7 patients were operated primarily after injury and in 11 patients the secondary reconstruction was performed. Authors called the attention to the high diagnostic difficulty before the planned and indicated secondary reconstruction. Based on assessment of own clinical material and conforming with literature, authors conclude that secondary reconstruction are more difficult, and this difficulty is the higher, the less qualified the primary treatment was performed.
