Success with sacrospinous suspension of the prolapsed vaginal vault.

Sacrospinous ligament fixation of the prolapsed vaginal vault has proved very useful, but the complications of failure, hemorrhage, infection, nerve damage, incontinence and dyspareunia are reported. Experience with 51 operations performed by staff, and residents with supervision, has shown the value of certain preoperative and technical steps to avoid complications, including candidate selection; repair of enterocele; retropubic positioning of the bladder neck; repair of all pelvic support defects, and perineorrhaphy. Technical modifications are described. Results in these instances are tabulated: no recurrent prolapse; no transfusions; four narrow vaginas; two with stress incontinence; one pelvic cellulitis, and one ventricular fibrillation on the third postoperative day. We believe that most complications are preventable.

Identification of Salmonella somatic and flagellar antigens by modified serological methods.

This report describes two modified methods for the identification of Salmonella somatic (O) and flagellar (H) antigens. Over a period of 2 years, both modified methods were found to be approximately three times less labor intensive than the standard methods while requiring no more technical skill. The modified methods were as accurate as the standard methods in identifying the O and H antigens of 350 Salmonella isolates. Furthermore, 43 O antisera reacted exclusively with organisms possessing homologous O antigens when the modified and two standard methods were used. At the antiserum dilutions used for H antigen identification, H antisera did not react with O antigens or heterologous H antigens by either the modified or the standard method. Compared with the standard method for H antigen identification, the modified method was approximately 20 times more economical with respect to antisera and usually generated a 1.5- to 4-fold higher titer. Since the antisera stored for use in the modified method for H antigen identification were usually 100-fold more dilute than the antisera stored for the standard method, an antibody-stabilizing buffer was incorporated in the diluted antisera, allowing these reagents to be used for at least 9 to 16 months.

The Pereyra procedure. Favorable experience with 200 operations.

This communication documents experience with 200 Pereyra operations performed for stress urinary incontinence over a 9 year period. The majority of patients were 35 to 55 years of age, were obese, and had varying degrees of uterovaginal prolapse. More than one fourth also had excessive bleeding and all were best managed by vaginal surgery. Important points in surgical technique are emphasized. Of 188 patients followed, 82 per cent had complete symptomatic relief and another 10.5 per cent were improved. There was a 7.5 per cent failure rate and morbidity was minimal. We conclude that the Pereyra procedure should be considered for stress urinary incontinence whenever vaginal surgery is indicated.
