These authors found that laparoscopic mesh repair of incidentally found Spigelian hernia resulted in a satisfactory repair with acceptable results.
The internal anal sphincter, the smooth muscle component of the anal sphincter complex, has an ambiguous role in maintaining anal continence. Despite its significant contribution to resting anal canal pressures, even total division of the internal anal sphincter in surgery for anal fistulas may fail to compromise continence in otherwise healthy subjects. However, recently reported abnormalities of the innervation and reflex response of the internal anal sphincter in patients with fecal incontinence indicate its significance in maintaining continence. The advent of sphincter-saving surgery and restorative proctocolectomy has re-emphasized the major contribution of the internal anal sphincter to resting pressure and its significance in preventing fecal leakage. The variable effect of rectal excision on rectoanal inhibitory reflex has led to a reappraisal of the significance of this reflex in discrimination of rectal contents and its impact on anal continence. Electromyographic, manometric, and ultrasonographic evaluation of the internal anal sphincter has provided new insights into its pathophysiology. This article reviews advances in our understanding of internal anal sphincter physiology in health and disease.
During a four-year period, 150 consecutive patients were treated for chronic pilonidal disease by one of three different operative techniques. Patients with acute pilonidal abscesses or with complex or multiple recurrent pilonidal disease were excluded from this study. The average healing time was four weeks and the average length of hospital stay was one day. The overall recurrence rate was 8 percent (12 of 150 patients). The method of management most commonly used was fistulotomy with marsupialization of the sinus tract or cyst wall (125 of 150 patients). This simple and effective technique gave excellent results with a 6 percent recurrence rate (7 of 125 patients). On the basis of their experience, the authors propose that chronic pilonidal disease usually can be treated successfully on a same day surgery basis with fistulotomy, minimal excision, and marsupialization.
A survey of 500 clinically active, board-certified colon and rectal surgeons in the United States and Canada was conducted to obtain data regarding current methods of bowel preparation for elective colorectal surgery. A review of recent publications on preoperative bowel preparation was used to compare the current literature recommendations with the actual practice among the group surveyed. Responses were received from 352 of 500 colorectal surgeons to whom questionnaires were sent (70 percent response rate). All respondents used a mechanical preparation and some form of antibiotics. The favorite antibiotic regimen was oral antimicrobials combined with systemic antibiotics (88 percent). Concomitant administration of oral neomycin-erythromycin base and a systemic second generation cephalosporin active against both anaerobic and aerobic colonic bacteria, together with oral polyethelene glycol electrolyte mechanical colonic cleansing, was the most popular method of preoperative bowel preparation (58 percent). The second most frequent method of mechanical bowel cleansing consisted of conventional enemas, dietary restrictions, and cathartic preparations (36 percent). Mannitol solution (5 percent), and whole-gut irrigation per nasogastric tube (1 percent) were the least popular methods of mechanical bowel cleansing. The literature supports the current methods of preoperative bowel preparation used by the vast majority of surgeons surveyed.
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.
