Abstract

Our purpose was to study the effect of unilateral pudendal neuropathy on the results of anal sphincter repair.Fifteen female patients who underwent external sphincter repair for fecal incontinence were studied. In all instances, incontinence was the result of obstetric delivery injury. Anal manometry and neurophysiologic investigations to document sphincter defects and pudendal neuropathy were performed in all patients. Sphincter repair was performed using an overlapping suture technique.All patients had anterior sphincter defects. Seven patients (47 percent) had pudendal neuropathy: six (85 percent) had unilateral neuropathy, and one (15 percent) had bilateral neuropathy. Six patients (40 percent) had excellent results; three (20 percent) had good results; four (27 percent) were improved; two (13 percent) experienced no improvement after sphincter repair. All patients with excellent results had normal pudendal nerve terminal motor latency on both sides. Of the three patients with good results, one patient had unilateral pudendal neuropathy. The patients in the remaining two groups (improved and failed) had unilateral (six patients) or bilateral (one patient) pudendal neuropathy.We conclude that both pudendal nerves must be intact to achieve normal continence after sphincter repair. Patients with unilateral pudendal neuropathy are more likely to have poor than to have good postoperative function. [ABSTRACT FROM AUTHOR]

29. Colonoscopy.

Author

Reilly, John C., Rusin, Lawrence C., and Theuerkauf, Frank J.

Abstract

In order to determine the feasibility, yield, and impact of routine total colonoscopy on the management of large-bowel cancer 157 cancer patients underwent 175 colonoscopic procedures; 13.6 per cent of the cancers had been missed on double-contrast barium enema examination.Among 92 patients undergoing perioperative colonoscopy, the lesion was reached in 89 per cent and the cecum in 60 per cent; 7.6 per cent demonstrated synchronous cancers, all curable, and all missed on barium-enema examination.Seventy-eight patients underwent colonoscopy at an average of 3.7 years after treatment of the index cancer; 7.7 per cent demonstrated metachronous cancers, all curable, two-thirds of which were missed on barium-enema examination.Benign polyps were noted in 62 per cent of the patients studied; 77 per cent of those polyps, 1 cm or greater in size, were missed on barium-enema examination. Polyps were found proximal to the cancer in 60 per cent of the patients with polyps. Approximately 85 per cent of those with multiple cancers demonstrated benign polyps. Preoperative total colonoscopy with periodic postoperative colonoscopy at an interval of three to five years are essential in the reliable detection of synchronous cancers and for the detection of metachronous cancers at an earlier, more favorable stage.
