Appendiceal mucocele - Case Report and Review of the Literature.

Appendiceal mucocele (AM) was described for the first time by Rokitansky in 1842.1 Its incidence is 0.2 - 0.

Extraskeletal Osteosarcoma of the Omentum with Aggressive Development.

For the first time extraskeletal osteosarcomas (ESOS) were described by Wilson in 1941. They are extremely rare neoplasms, presenting 4% of all osteosarcomas and 1,2% of all soft-tissue sarcomas. About 300 cases have been reported in the literature up to date.

Recurrent perineal hernia -- case report and review of the literature.

Perineal hernia is the protrusion of intra-abdominal viscera through the pelvic floor. We present a patient with recurrent perineal hernia - 12x9 cm with a palpable soft, hardly adjustable in the pelvic tunnel formation and attenuated skin over it. The patient was operated by abdominoperineal approach.

Management of recurrent or metastatic retroperitoneal soft-tissue sarcomas.

Unlabelled: Retroperitoneal soft tissue sarcomas remain a serious therapeutic problem. The aim of the study is to define the optimal treatment strategy of patients with locally recurrent or metastatic retroperitoneal soft tissue sarcomas.

Material And Methods: A retrospective study was performed.

Health insurance coverage, income distribution and healthcare quality in local healthcare markets.

We develop a theoretical model of a local healthcare system in which consumers, health insurance companies, and healthcare providers interact with each other in markets for health insurance and healthcare services. When income and health status are heterogeneous, and healthcare quality is associated with fixed costs, the market equilibrium level of healthcare quality will be underprovided. Thus, healthcare reform provisions and proposals to cover the uninsured can be interpreted as an attempt to correct this market failure.

[Polyposis of the colon and cancer].

Polyposis of the colon is a colon cancer predisposition syndrome. Familial adenomatous polyposis (FAP) accounts for 1% of the cases of inherited colorectal cancer (CRC). The National Register of inherited CRC and polyposis of the intestines keeps track of 18 patients from 14 families with FAP.

[Endoluminal echography in rectal cancer--preoperative staging and postoperative control].

The aim of this study is to determine the diagnostic potential of endoluminal echography and the pitfalls sources in the preoperative staging and postoperative follow-up in patients with rectal cancer. 245 patients with rectal carcinoma are evaluated during 10 years period (Jan. 1993-Jan.

[Percutaneous puncture treatment of hepatic cystic echinococcosis under ultrasound guidance].

Introducing of the alternative PAIR (puncture-aspiration-injection-reaspiration) method for treatment of hepatic echinococcosis in practice dates from 1992 year. A Working group dealing with the problems and standardization of the method has been created by WHO. The major aspects of this treatment are summarized in the bulletin of WHO of 1996 year.

[Local recurrence after radical surgery for rectal carcinoma].

The incidence rate of local recurrences after radical operative treatment of rectal carcinoma and the risk factors involved, methods of early diagnosis and surgical therapeutic approach are comprehensively analyzed. Reference is also made to 86 scientific publications on the issue. During the 20-year follow-up period, no tendency of the incidence of local rectal carcinoma relapses to decrease is noted.

[Mucinous breast carcinomas with neuroendocrine differentiation].

Mucinous breast carcinomas, denominated also gelatinous, mucoid and colloid (collomas), represent a heterogeneous group of neoplasms. More than half of them exhibit signs of neuroendocrine differentiation. Eighteen mucus producing carcinomas of the breast are subjected to morphological study.

[Reoperations on the biliary system].

Reoperations of the biliary apparatus is a branch of biliary surgery still not well enough clarified and difficult to cope with. A total of 169 patients are subjected to operation and investigation in the clinic of abdominal surgery. In 71 of them reoperation is undertaken over the period 1952-1973, and in 97--in the period 1974 through 1993, representing 8.

[The indications and choice of the technic for pancreatic resections].

The progress of pancreatic surgery naturally leads to broadening the scope of indications for resection of the gland. Over the period 1970 through 1993, in the Clinic of Abdominal Surgery are performed 99 pancreatic resections for carcinoma of the pancreas (including cancer of papilla Vateri (45), endocrine-active tumor of pancreas (5), benign tumor (1), chronic pancreatitis (4), pseudocysts of the pancreas (4), cancer of an adjacent organ infiltrating the pancreas (36), benign lesions to a neighbouring organ (4). The size of resection depends on a number of factors of which location of the neoplasm and stage of the disease are the leading ones.

[Pancreatic cancer. The experience with its surgical treatment].

Experience had with the surgical management of 483 patients, operated for cancer of the pancreatic gland in the Clinic of Abdominal Surgery over the period 1971 through 1994, is presented. Distribution of the patients by gender and age shows noteworthy consistency. Preoperatively, exact diagnosis in the clinic is made in 91.

[The surgical and alternative treatment potentials in biliary tract cancer. I. Surgical treatment].

Biliary apparatus cancer is a rare condition characterized by low operability percentage. This is a comparative study of two series of patients, operated during the periods 1952-1979 and 1980-1994. In the first observation period (28 years) 119 patients are operated, and in the second 13-year period a total of 206 patients are subjected to operative and endoscopic treatment.

[The choice of the operation and management in cholangitis].

Irrespective of the high rate of bacterial flora (intestinal, respectively) penetration into the biliary apparatus, clinically manifested cholangitis cases are relatively seldom met with. The predisposing factors involved are: penetration of virulent flora (anaerobic inclusive) into the bile ducts, presence of conditions promoting delay or discontinuation of the bile passage (biliary hypertension), and longstanding of the disease. Cholangitis associated with cholangiohepatitis development is one of the severest conditions of cholelithiasis (ChL), being observed as an independent nosological entity also.

[The surgical and alternative treatment potentials in biliary tract cancer. II. Alternative potentials].

The modern diagnosis of biliary tract cancer is still unsatisfactory regardless of the introduction of updated instrumental diagnostic methods. The latter may undergo development and transformation into therapeutic procedures. Patients with increased operative risk, and those presenting locally intractable neoplasm or metastases are indicated for this kind of alternative therapeutic approach.

[Endoscopic sphincterotomy in choledocholithiasis and an intact gallbladder].

Endoscopic sphincterotomy (ES) with extraction of calculi is a basic method of treating choledocholithiasis in post-cholecystectomy patients (8, 9). Endoscopic treatment contributes to a considerable reduction of the indications for reoperation. The existing views concerning ES done in patients with preserved gallbladder, especially in the era of laparoscopic surgery, are still conflicting (3, 6).

[Postoperative peritonitis].

This is a report on retrospective summed-up analysis of the therapeutic approach to 296 patients presenting postoperative peritonitis (PP). They account for 1.4 per cent of the total number of patients operated on in the clinic.

[Endocavitary echography following abdominoperineal extirpation of the rectum].

Transrectal echography using a high-frequency transducer is a well established method for preoperative rectal carcinoma assessment, and for postoperative follow-up of patients with anterior resection for rectal carcinoma. Having in mind the impossibility for follow-up study of patients with abdominal perineal extirpation of the rectum by transrectal echography, a new pattern of application of the transducer employed for endorectal examination is suggested. In five patients (4 women and 1 man) endocavitary echography through the anal canal is done.
