Radiographic comparison between male and female patients with lumbar spondylolysis

We studied the lumbar spines of 117 adults (39 women and 78 men) with spondylolysis unrelated to low back pain using multidetector computed tomography (CT). Of the 117 subjects with spondylolysis, including five with multiple-level spondylolysis, there were 124 vertebrae with spondylolysis. In adult lumbar spines with unilateral spondylolysis, there was no significant difference between the incidence of spondylolisthesis in female and male subjects. However, in those with bilateral spondylolysis, there was a significantly higher incidence of spondylolisthesis in female subjects (90.9%) than in males (66.2%). Furthermore, females with bilateral spondylolysis had significant more slippage than males. Lumbar index and lumbar lordosis were not significantly different between male and female subjects, and did not significantly correlate with slippage. In conclusion, to treat acute spondylolysis in adolescents, it is important to obtain bony union at least unilaterally, especially in female subjects, to prevent further slippage

The upper limit normal values are indicated by dashed lines. The post values are the highest titers observed during the follow-up periods. Each dot represents a single serum sample, and the data are presented as mean ± SEM. A paired <i>t</i>-test for intra-group comparison or the Mann-Whitney test for inter-group comparison was used. ns: not significant.</p

Laparoscopic cholecystectomy : Our experience of 75 consecutive cases

We peformed 75 consecutive laparoscopic cholecystectomy from July 1991 to October 1993 on the patients with gallstones and/or gallbladder polyps. The patients consisted of 30 males and 45 females between 32 and 88 years old with a mean age of 59.4 years. In 72 of these 75 patients (96.0%) laparoscopic cholecystectomy was successfully completed. In the remaining 3 cases (4.0%) the operation was converted to the open cholecystectomy. All patients were free of major complications. Three patients required conversion to a conventional open cholecystectomy due to fallen gallstones in the peritoneal cavity, dense adhesions surrounding the gallbladder and severe acute cholecystitis. This procedure is advantageous in comparison with the conventional open cholecystectomy, because of less postoperative pain, rapid postoperative recovery and high cosmetic value as well. Laparoscopic cholecystectomy seems to be a safe and effective treatment for selected patients with benign gallbladder diseases

Laparoscopic cholecystectomy in patients with nonvisualizing gallbaldder by DIC and previous upper abdominal surgery

Between July 1991 and December 1993, 80 patients with gallstone and/or gallbladder polyp were considered candidates for laparoscopic cholecystectomy. We attempted 7 cases of laparoscopic cholecystectomy for patients with nonvisualizing gallbladder by DIC, and in 6 cases, the laparoscopic cholecystectomy was successfully completed. In the remaining 1 case the operation was converted to open cholecystectomy due to severe acute cholecystitis. During the same period, there were 8 patients who had previous upper abdominal surgery, and in 4 of these patients, laparoscopic cholecystectomy was successfully completed. All patients were free of major complications intra and postoperatively. We can extend the indications for laparoscopic cholecystectomy as skill with this procedure increases. We believe that this procedure will become the standard operation for benign gallbladder diseases in the near future in Japan
