[Gastric polyposis in surgical practice. Apropos 12 cases].

Personal experience is recorded in the surgical treatment of 12 patients with gastric polyposis at the Department of Propaedeutics of Surgical Diseases of the Research Institute of Surgery, for a period of 10 years (1981-1990). They accounted for 75 per cent of the benign neoplasms of the stomach and 4.08 per cent of all gastric tumors. The results of operative treatment, both in patients treated by gastric resection according to Billroth I technique (58.3 per cent) and in patients who were treated only by removing the polyps (41.7% per cent) were considered good within a follow up period of 1 to 5 years after the intervention. Proceeding from modern achievements and reports in the literature, the authors place accent on some important current aspects of treatment and observation on gastric polyps, their correlation with a number of hyperplastic diseases and malignant neoplasms of the stomach and colon.

[Intra-arterial chemotherapy in the treatment of liver metastases from colorectal carcinoma].

After a brief review of the literature the authors analyse the different invasive methods for treatment of liver metastases, rendering preference on intraarterial chemotherapy (IACT). The indications and contraindications for IACT and the possible complications of this approach are determined. The drugs for IACT, the types of implantable devices and the techniques for their application are shown. Criteria for assessment of the effect of treatment are determined. Experience is recorder with 3 patients with anterior resection of rectum and nonresectable liver metastases. The result was failure in 1 patient and very good in the other two.

[The surgical and endoscopic therapeutic procedures in acute hemorrhages of the upper digestive tract].

A total of 2995 patients with esophagogastroduodenal bleeding have been treated the Department of Emergency Surgery for the period 1984-1988. A significant group were patients in advanced and senile age (beyond 65--42.4 per cent). The therapeutic and surgical approach to gastroduodenal bleeding was based on the solution of the following diagnostic-tactic problems: cause, source, localization and intensity of the bleeding, temporary or definitive hemostasis patterns, severity of blood loss. Essential is also the underlying disease, patient age and accompanying diseases. Express emergency endoscopy allows early and explicit visualization of the pathologic area and enables to gain knowledge on the nature and intensity of the bleeding or the character of spontaneous hemostasis. In this respect, express endoscopy is a guiding principle in managing upper digestive tract bleeding at the Department of Emergency Surgery. Of all hospitalized patients in this study were operated 203. Operations were performed after obligatory attempt for endoscopic hemostasis. The operative case fatality rate for the study period was, as follows: in gastric and duodenal ulcer 21.6 per cent, in gastric cancer 42.0 per cent, in hemorrhagic gastritis 33.3 per cent and in Mallory-Weiss syndrome 9.1 per cent.

[Abdominal adhesion disease--the diagnostic and surgical problems in emergency surgery].

Reviewing the literature, the authors discuss the diagnostic and surgical problems of abdominal adhesion disease in emergency surgery. The etiology and pathogenesis of adhesion disease is complex and still poorly understood. A number of etiologic factors are considered responsible. The authors formulate the current concepts on the pathogenesis of this disease and some classifications in the world literature. Adhesion disease is a major problem in emergency surgery, especially the form known as acute breed ileus. The prophylaxis, conservative and adequate operative treatment are of great importance.

[Cholelithiasis, cholecystectomy and colorectal cancer--a retrospective analysis].

The authors analyzed a series of 421 patients with colorectal cancer after preliminary review of the current literature and the modern theories of the origin of the disease. The patients have been treated at the Department of Propedeutics of Surgical Diseases, Research Institute of Surgery, for the period 1984-1990, and special accent was placed on the study of the relation of colorectal cancer to cholelithiasis and cholecystectomy. It was shown that 1.19 per cent of all patients had been cholecystectomized at mean 10.6 years back and 6.65 per cent had pre-existing or accompanying biliary calculosis with mean duration of symptoms 16.4 years. A major relationship was found between morbidity from colorectal cancer, on the one hand, and patient sex and biliary calculosis, on the other. Eighty nine per cent of the patients with colorectal cancer and with biliary calculosis treated by cholecystectomy were women and 20.3 per cent of the women with colorectal cancer had biliary calculosis and had been cholecystectomized. Attention is focused on the current practical requirements of the prophylaxis of colorectal cancer--adequate attitude to biliary calculosis, feeding habits, specifying cases at risk and their observation.

[Pancreatic cancer. VII. The incidence and characteristics of the metastasis of pancreatic adenocarcinoma].

The study demonstrated that adenocarcinoma was the most common form of pancreas cancer. In the majority of cases it originated from the head of the gland, with the body ranking second and the tail third. Adenocarcinoma most frequently metastasized in the lymph nodes, less in the liver and rather infrequently in the lungs and intestines. When the cancer involved the entire gland or a greater part of it, metastases in the latter organs were practically obligatory. Most frequently metastases of pancreas adenocarcinoma were observed in the seventh decade, followed by the sixth and the eighth decades. This regularity as a whole matched the regularity of the age prevalence of pancreas cancer.

[Primary malignant non-Hodgkin's lymphoma of the large intestine].

A case is reported of primary malignant non-Hodgkin's lymphoma of the colon of a 85-year-old woman. The clinical manifestations and the X-ray pattern were those of cancer. The diagnosis was established on post-mortem examination. Histologically this was a centroblastic-centrocytic lymphoma of Brill-Symmers with low-grade malignancy. The clinical, diagnostic, prognostic and therapeutic problems in malignant non-Hodgkin's lymphomas of the colon are discussed.

[Closure of the double-barreled colostomy].

In a survey of the literature the authors discuss the problem of double-barreled colostomy closure, which a remains controversial. The high percentage of postoperative complications--up to 50 per cent and mortality up to 2.1 per cent are responsible for nondetermination of the method of choice, depending on the type of colostomy, of the colostomy complications and the absence of indications for choice of the time of colostomy closure.

[Extrarenal changes in the isotopic nephrogram of surgical patients with abdominal pathology and the potentials for an erroneous interpretation].

Eighty-three patients with surgical abdominal pathology were included in the study. On the isotopic nephrogram they all had bilateral symmetric and analogous pathologic changes with varying degree of severity. The most common cause of renal function changes in patients with abdominal pathology was the reduced intravascular volume or vascular capacity changes, registered on the isotopic nephrogram with characteristic symmetrical pathologic curves. The sharp renal perfusion decrease, leading to decrease of glomerular filtration and diminution of diuresis explains the bilateral changes in the isotopic nephrogram which most frequently resemble obturation. The curves returned to normal 1 to 2 weeks after the physiologic state of the patients was stabilized, indicating extrarenal origin of the registered changes in the isotopic nephrogram. The latter should carefully be interpreted, in view of the possible influence of it of extrarenal factors.
