Diagnostic gastrointestinal laparoscopy: experience and changing indications.

We reviewed the records of all 117 patients who underwent diagnostic laparoscopy at our clinic from 1980 to 1985. There were no deaths or marked complications from the procedure. Accurate diagnosis was made in 72% of 79 patients with abdominal pathology; of these, 81% of 63 patients had hepatic pathology, and 44% of 16 patients had extrahepatic pathology. Of 27 patients with conditions that might have justified exploratory laparotomy, diagnosis was made in 48%. Of 29 patients who underwent preceding nondiagnostic blind-needle biopsies of the liver, laparoscopy established a diagnosis of cirrhosis or neoplasm in 44%. A parenthetical finding was that at our institution liver scan alone appeared to be the most adequate imaging workup of suspected hepatic disease. Our data support the use of laparoscopy for diagnosis of hepatic disease and as a first step prior to purely diagnostic laparotomy.

Sabin-Feldman dye test in ulcerative colitis and Crohn's disease.

The prevalence of Toxoplasma infection among patients with inflammatory bowel disease was studied. The Sabin-Feldman dye test was performed on 35 patients with Crohn's disease, 44 patients with ulcerative colitis, and 140 control patients. A higher incidence of positive reactions was found in Crohn's disease patients over the age of 40 (P less than 0.05). All other factors showed no significant differences among the three groups of patients. These factors include age younger than 40 years, sex, duration of disease, extent of disease, and type of treatment. It is concluded that there is no correlation between inflammatory bowel diseases and toxoplasmosis. Toxoplasma infection, however, should be considered in patients with Crohn's disease who are over 40 years old, and who present with nonspecific signs of intercurrent infection.

Energy intake and body weight in ovo-lacto vegetarians.

Vegetarians have a lower body weight than omnivores. In this study the relationship between the weight/height ratio and food consumption was evaluated in 92 ovo-lacto vegetarians and 113 omnivores in Israel. The average weight of the vegetarians was significantly lower than that of the omnivores (60.8 kg vs. 69.1 kg), even though the vegetarian diet supplied a significantly higher amount of calories than the nonvegetarian diet (3,030.5 cal/day vs. 2,626.8 cal/day). Consumption of fat was similar in both groups. Carbohydrate consumption was higher in the vegetarians while protein consumption was lower. The prevalence of obesity was significantly lower in the vegetarian group (5.4%) as compared to 19.5% among the omnivores. The lower body weight of vegetarians despite a higher caloric intake is of considerable interest.

Mineral intake and blood levels in vegetarians.

Concern has been raised that a long-term high-fiber diet may lead to mineral deficiencies. In this study, mineral intake and blood levels were investigated in 92 ovolacto vegetarians and 113 omnivores. The intake of iron, zinc, calcium and magnesium was adequate in both groups. The intake of iron and magnesium was significantly higher in the vegetarians. Mean blood levels of iron, iron binding capacity, calcium, phosphorus, alkaline phosphatase, zinc and magnesium were within normal limits in both groups. Serum magnesium levels were significantly higher in male vegetarians. Iron binding capacity was significantly lower in vegetarians of both sexes. It is concluded that a long-term ovolacto vegetarian diet does not lead to mineral deficiencies.

Manometric study during endoscopic retrograde cholangiopancreatography--a new technique for the evaluation of pathology in the pancreatic and biliary systems.

During endoscopic retrograde cholangiopancreatography, pressures of the common bile duct, the pancreatic duct and the sphincter of Oddi were recorded in 64 patients with various diseases of the pancreaticobiliary system. The manometric study was found to be helpful in the diagnosis of papillary dysfunction and in the assessment of the adequacy of papillotomy and the size of a choledochoduodenostomy. Furthermore, it is possible that nitrates may be effective in the treatment of patients with papillary dysfunction.

Selective screening for colorectal tumors in the Tel-Aviv area: relevance of epidemiology and family history.

A selective screening program for the early detection of colorectal tumors was carried out in the Tel-Aviv area. The criteria for inclusion were based, in part, on relevant epidemiologic data which showed that European- and American-born immigrants were at the highest risk for developing this cancer, followed by Israel-born Jews. The Tel-Aviv area, because of its large elderly population of European origin, has a high incidence of colorectal cancer. Families of patients with colon cancer are known to have an increased risk for developing colon tumors. These relatives were actively searched for, and were, along with the control group, examined by Hemoccult testing and flexible sigmoidoscopy. The color tumor (cancer or adenomatous polyps) rate was 6.3% in the group with a family history of colon cancer, as contrasted to 3.8% in a smaller control group without this history. This increased yield, greater than usually found in an unselected population, emphasizes the economic value of selective screening utilizing relevant epidemiologic data and the family history.

A high-fiber diet does not cause mineral and nutrient deficiencies.

We evaluated the hypothesis that a healthy population taking a high-fiber diet may develop deficiencies of various minerals and nutrients in three groups of healthy subjects: 1) sixty-eight people regularly supplementing their diet with at least 2 tablespoons of bran for at least 6 months (mean 3 tablespoons for 13 months); 2) forty-three controls not consuming bran supplements; and 3) twenty vegetarians (eight of them consuming bran supplements) who had a very high fiber consumption for many years. The mean serum levels of iron, total iron binding capacity, calcium, phosphorus, alkaline phosphatase, zinc, magnesium, vitamin A, and cholesterol were within the normal range in all the three groups. In the bran eaters, vitamin A was higher, and alkaline phosphatase and magnesium lower than in the other two groups. In the vegetarians, the phosphorus level was higher and cholesterol and iron binding capacity lower than in the other two groups. There was no correlation between the amount of bran consumed and the blood level of nutrients. The fiber consumption of the vegetarians was very high, more than three times that of the controls. Our study indicates that a moderately or even extremely high consumption of fiber for a long time does not by itself cause mineral or nutrient deficiencies in a western type population.
