OBJECTIVE Mediolateral episiotomy is associated with lower rates of significant perineal tears than midline episiotomy. However, the relationship between precise angle of episiotomy from the perineal midline and risk of third-degree tear has not been established. This study quantifies this relationship. DESIGN Case-control study. SETTING National(More)
A family with autosomal dominant inheritance of sacral agenesis is described. Ten members were affected; four had associated presacral teratomas and anterior sacral meningoceles, giving rise to serious complications in three, including bacterial meningitis, local recurrence of teratoma and perianal sepsis. Three of those with presacral masses presented(More)
INTRODUCTION Over one-third of patients with Crohn's disease (CD) will develop an intestinal stricture and the great majority of these will require at least one surgical procedure. While the pathogenesis of inflammation in CD has been extensively investigated, knowledge of stricture pathogenesis remains limited. The aim of this review is to discuss the(More)
BACKGROUND Ultrastaging, by serial sectioning combined with immunohistochemical techniques, improves detection of lymph node micrometastases. Sentinel lymph node mapping and retrieval provides a representative node(s) to facilitate ultrastaging. The impact on staging of carcinoma of the colon and rectum in all series emphasizes the importance of this(More)
The aim was to determine whether changes in enteric bacteriology, absorption, morphology, and emptying occur after ileal pouch-anal anastomosis for ulcerative colitis, and to relate any changes to the clinical result. Twenty patients were studied 26 +/- 2 months (mean +/- s.e.m.) after operation. Eight patients had a good result, six a poor result, and six(More)
The aim of our study was to determine whether ileal pouch motility and evacuability and the 24 hour fecal output influence stool frequency after ileal pouch-anal anastomosis. In 23 patients, at a mean of 24 months postoperatively (range 22 to 26 months), ileal pouch motility was measured using an intraluminal bag and pressure-sensitive catheters. The(More)
BACKGROUND Because obstetric injury to the anal sphincters may be occult, and because the mechanism of injury differs between first and subsequent deliveries, we prospectively assessed the effects of first and second vaginal deliveries on anal physiology and continence. METHODS We undertook a prospective observational study of 59 previously nulliparous(More)
PURPOSE This study was designed to compare prospectively the effects of augmented biofeedback with those of sensory biofeedback alone on fecal incontinence and anorectal manometry after obstetric trauma. METHODS A consecutive cohort of 40 females with impaired fecal continence after obstetric anal sphincter injury were recruited from a dedicated perineal(More)
Regeneration of rectal mucosa after rectal mucosectomy and ileoanal anastomosis (IAA) could jeopardize the long-term safety of the procedure. The aim of this study was to determine if rectal mucosal regeneration occurred after IAA. Pathologic specimens of the IAA and surrounding rectal muscular cuff were obtained from 29 patients who had required IAA(More)
