Research unit of hydatidology of people's hospital of Xinjiang Autonomous Region, Urumqi, 830001 P.R. China There were 1,640 patients with hydatid disease who underwent surgical treatment in our hospital during 1953-1990. of these, 1,204 cases were liver hydatid disease, and 1,319 operations yielded 1,716 Echinococcus cysts. The methods of removal of hydatid cyst were: 1) hepatic lobectomy 2) removal of intact hydatid cyst 3) removal of hydatid cyst by aspiration. Removal of the cysts left in the liver residual ectocyst cavities as large as the cysts and bile-containing bloody retention cyst, usually resulted in secondary infection, causing liver abscess. The clinical observations and experimental studies of this series revealed the mechanism of intrahcpatic biliary fistula formation and the natural rule of cavity closure, allowing rational cavity management and modification of operative methods. This reduced the frequency of postoperative biliary fistula and of secondary infection, and also shortened the healing period. The video shows a case of hydatidosis of the left hepatic lobe, appearing on the surface of the parenchyma. Cisto-pericistectomy was performed. This is the treatment of choice, because it doesn't cause reduction of the functional parenchyma and has better possibilities for radical. Benign bile duct strictures are occasionally seen in early infancy. Usually, no cause can be identified and the stricture is said to be "congenital". Spontaneous bile duct perforation is a rare entity which occurs in the first 12 weeks after birth. This disease may present as a subacute illness with jaundice, acholic stools, failure to thrive and progressive biliary ascites. A pseudocyst may be found in the hepatoduodenal ligament at laparotomy. Both spontaneous perforation and the stricture of the duct tend to be located just proximal of the junction of common bile duct and cystic duct. We have analyzed our patient material in order to asses whether infants treated for a neonatal bile stricture could have had a bile duct perforation prior to the clinical manifestation of the stricture. Three cases were found. Two of them had a Roux-en-Y hepaticojejunostomy for a bile duct stricture located at the junction of the common bile duct and the cystic duct at an age of three and 20 months respectively. One infant had a transient period of moderate jaundice associated with dilated intrahepatic ducts at an age of one week. The other child had a period of melaena and haematemesis presumably caused by haemobilia two months after birth. In both cases the symptoms resolved spontaneously. The third infant had an explorative laparotomy for extrahepatic cholestasis five weeks after birth. A pseudocyst filled with bile was found which was located in the hepatoduodenal ligament. The cyst was drained. The perforation site could not be identified. Two weeks after surgery, a biliary fluid collection was drained percutaneously. These cases suggest that spontaneous bile duct perforation might pass unobserved when located in the hepatoduoden...
The incidence of urinary infection before and after operation for benign prostatic hypertrophy has been reviewed in 140 patients. Repeated screening for bacteriuria was used throughout the hospital admission. Infection was present in 24% before operation and there was a significant correlation between the incidence of infection and the duration of preoperative catheterisation. Postoperative infection developed in 31% and there was no relation between this incidence and the type of prostatectomy; specific antibacterial therapy was significantly more effective in eradicating urinary infection acquired after operation than before. At the time of discharge from the ward, 10% had infected urine, but only 3% of patients had persistent infection at follow-up 6 weeks after operation.
SummaryTo assess the value of the Uricult dip-slide in a hospital urological unit, bacteriological examination of 1,033 urine specimens was compared by this technique and by conventional methods. In 87% of cases identical results were obtained using the dip-slides and the standard laboratory culture plates. Insignificant differences occurred in 10%, and a serious discrepancy between the two methods was found in only 3 %. The Uricult dip-slide technique is valuable as a bacteriological screening procedure in urological practice but subculturing from the slide is not recommended except in special circumstances.
Forty subfertile men with oligospermia were treated with a synthetic androgen (Mesterolone). The effect of the drug was evaluated by measuring serum testosterone, luteinizing hormone (LH), follicle stimulating hormone (FSH) and analysing the semen before and after treatment. The results demonstrated that in twenty-three patients treated for 6-9 months there was a significant decrease in serum testosterone (P less than 0.01); the means +/- SEM before and after treatment were 17.05 +/- 0.95 and 14.7 +/- 0.95 (nmol/l serum) respectively. There was a pronounced increase in serum LH (P less than 0.01), the values being 2.73 +/- 0.26 and 3.61 +/- 0.3 (u/l) respectively. However, no significant difference was found in serum FSH before and after treatment. The sperm concentration showed a variable response to treatment. In twenty-one patients there was either no change or worsening in the sperm concentration, whereas in nineteen patients an improvement was observed. The analysis of variance of sperm concentration and motility for the periods before and after treatment, for all the patients, showed no significant difference in the sperm concentration F1.145 = 2.82 (P=0.1).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
