Long-term outcome after intestinal resection for Crohn's disease.

OBJECTIVE: To assess the need for intestinal repeat resection for recurrence of Crohn's disease in patients observed for more than 20 years after the first resection. MATERIAL AND METHODS: Data were gathered retrospectively from the medical records of 53 (28 F) consecutive patients with Crohn's disease from May 1954 to December 2002. Median age at first intestinal resection was 24.5 (range 13-65) years, and median observation time thereafter was 26.5 (20.1-48.6) years. Disease location and behaviour were defined according to the Vienna classification. RESULTS: The 53 patients had an average 2.7 and a median 2 intestinal resections. Out of 144 intestinal resections (77.1%) 111 were performed during the first three operations; no alterations in distribution of ileal, ileocolic and colic resections were found. From the first to the third operation there was an increase in penetrating disease from 15% to 39% (p=0.046) concomitant with a decrease in stricturing disease from 72% to 44% (p=0.048) of the patients. There was also a corresponding decrease in ileocolic disease from 45% to 5% (p=0.003) and a tendency towards an increase in ileal disease from 38% to 67%. One patient died (1.8%) from rectosigmoid perforation after the third resectional operation. Six patients needed reoperation (11.3%) for ileus, anastomotic bleeding, rectosigmoidal perforation and abdominal pain. Thirty-four patients (64.2%) needed intestinal repeat resection (median 8.3 years) during 25.3 years after the first repeat resection. CONCLUSIONS: This study indicates a diminution of Crohn's disease activity with time, as demonstrated by no need for intestinal repeat resection more than 25 years after the first resection.

[Surgery and stenting for oesophageal cancer].

BACKGROUND: The purpose of this study was to evaluate the results of surgery and stenting for operable and inoperable oesophageal cancer. MATERIAL AND METHODS: Retrospective patient materials with resection (n = 65, 1983-2002) or stenting (n = 59, 1994-2003) for primary oesophageal cancer. RESULTS: Mortality after surgery was 11% and 15% of the patients were re-operated. 36 (55%) had complications such as respiratory failure (n = 33), anastomotic dehiscence/perforation (n = 4), chylothorax (n = 1), haemorrhage (n = 3), wound rupture (n = 1), septicaemia (n = 2), arrhythmia (n = 4) and wound infection (n = 5). Median survival after surgery was 11 months. Survival after three years was 17%, after five years 8%. The stent procedure was without mortality but haemorrhage (n = 1) and stent dislocation (n = 2) occurred. 8 patients (14%) were re-stented for tumour stenosis (n = 6), fistula (n = 2) and dislocation (n = 1). Median survival after stenting was 78 days. Survival after 30 days was 80%, after one year 7%. INTERPRETATION: Resectable oesophageal cancer should be operated in fit patients, as survival is improved and some patients can be cured. Stenting is the main option in inoperable patients.

[Internal rectal invagination treated with rectopexy and sigmoid resection].

BACKGROUND: Internal rectal intussusception, usually occurring in women, causes constipation and incomplete evacuation of stool. MATERIALS AND METHODS: Twenty-one women and one man (median age 48) were operated with suture rectopexy and sigmoid resection. The patients were examined with anoscopy and defecography, and symptomatic outcome, patients' satisfaction and morbidity were evaluated. Outcome was based mainly on the validated KESS score for constipation. RESULTS: There was a significant reduction in all ten symptoms. Faecal incontinence improved in the two afflicted patients after operation. The number of patients with constipation was reduced from 20 to 8 (p < 0.01); none became constipated. Mean (95 % CI) colonic transit times in ten constipated patients was reduced from 5.3 (4.1-6.4) to 4.0 (2.6-5.4) days (p = 0.08); seven of these patients had a reduction of transit time as well as constipation score. INTERPRETATION: Rectopexy with sigmoid resection improved symptoms, including constipation and feeling of incomplete rectal emptying.

[Surgical treatment of anal fissure].

BACKGROUND: Anal fissure is very painful; surgery is warranted when medical treatment fails. MATERIAL AND METHOD: We present a retrospective study of 34 patients (median age 42; 19-63) treated by subcutaneous lateral internal sphincterotomy (n = 27) and anal dilatation (n = 7) from 1992 to 2002, carried out by a questionnaire on pain, anal incontinence, and treatment result. RESULTS: There were no complications or treatment for recurrence of anal fissure. Median pain score before surgery was 7.3 on a scale from 0 (no pain) to 10 (worst imaginable pain), median 73 months (4-124) after surgery the median score was 0 (0-5) (p = 0.00). For sphincterotomy (n = 27), the median score was 7.8 before surgery and 0 (0-5) after (p = 0.00), for anal dilatation 6 (3-10) before surgery and 2 (0-2) (p = 0.01) after. All patients had reduced pain scores after surgery but their incontinence scores remained unchanged. Two patients (7%) who had previously been dilated or irradiated developed faecal incontinence after sphincterotomy. More patients became asymptomatic after sphincterotomy (n = 18; 67%) than after anal dilatation (n = 4; 57%). INTERPRETATION: Compared to anal dilatation, sphincterotomy offers better pain relief for anal fissure. Doing a shorter sphincterotomy corresponding to length of the fissure reduces the risk of anal incontinence.

[Secondary anterior sphincteroplasty for anal incontinence after delivery].

BACKGROUND: The prevalence of anal sphincter rupture at vaginal delivery is from 0.5 to 2.5 %. More than 50 % of these patients may need a secondary anterior sphincteroplasty because of anal incontinence. MATERIALS AND METHODS: We present prospective series of 29 women (median age 45 years) operated with an overlapping anterior sphincteroplasty from 1996 to 2001. The patients were examined with anal ultrasonography (n = 23), manometry (n = 19) and neurophysiologically (n = 13), and divided into group 1 (n = 19) with anal sphincter rupture and group 2 (n = 10) with sphincter rupture as well as pudendal neuropathy. All patients (n = 29) were examined with the Cleveland Clinic incontinence score before and median eight (2-64) months after operation. RESULTS: Median incontinence score before and after operation was 11.0 (0-22) versus 5.0 (0-16) (p = 0.002) for group 1; 18.0 (15-24) versus 15.5 (11-24) (p = 0.034) for group 2. There was also a significant difference between the groups concerning incontinence scores both preoperatively (p = 0.045) and postoperatively (p = 0.028). An improvement of continence was seen in 15 (79 %) of the patients in group 1 compared to 4 patients (40 %) in group 2. In group 1 a significant increase of median resting and squeeze pressures was seen. INTERPRETATION: Anterior sphincteroplasty improves anal continence considerably in patients with isolated sphincter rupture. However, patients with evidence of pudendal neuropathy must be informed that they should expect only a minor improvement in continence after operation.

Early evaluation of bowel symptoms after primary repair of obstetric perineal rupture is misleading: an observational cohort study.

PURPOSE: This study was conducted to investigate the long-term development of anal and urinary incontinence and to investigate the clinical value of electromyography and pudendal nerve terminal motor latency after obstetric anal sphincter rupture. METHODS: One hundred females with obstetric anal sphincter rupture were evaluated by an anal incontinence questionnaire at 5 and 18 months postpartum and by a urine incontinence questionnaire at 18 months postpartum. Pudendal nerve terminal motor latency and electromyography examinations were performed on 68 and 67 females, respectively, at 10 months postpartum. RESULTS: Fecal incontinence increased from 7 to 17 percent between 5 and 18 months (P = 0.04). At 18 months, the incidence of anal incontinence in females working outside the home (42/70 (60 percent)) was greater than that for females still at home with their child (12/30 (40 percent); P = 0.05). Anal incontinence at 18 months was significantly higher (P = 0.01) in subjects with pathologic electromyographic findings (76 percent) than in those with normal electromyography (45 percent; observed differences, 31 percent (95 percent confidence interval, 9 to 54 percent)). Thirty percent of the subjects had urinary stress incontinence. The risk of fecal urgency was greater in females with urinary urgency (difference, 44 percent; 95 percent confidence interval, 18 to 69 percent) and urinary stress incontinence (difference, 24 percent; 95 percent confidence interval, 3 to 44 percent) than in those without. CONCLUSION: Fecal incontinence symptoms worsen with increased follow-up time, and the change in working status is the most likely explanation; therefore, early evaluation of bowel symptoms is misleading. Denervation injury of the anal sphincter is an independent risk factor for anal incontinence but has no association with urinary incontinence. Urinary urgency and stress incontinence symptoms are strongly associated with fecal urgency.

Resection rectopexy for internal rectal intussusception reduces constipation and incomplete evacuation of stool.

OBJECTIVE: To study the effect of rectopexy and sigmoid resection (resection rectopexy) on symptoms in patients with internal rectal intussusception. DESIGN: Retrospective and prospective study. SETTING: University hospital, Norway. PATIENTS: 22 patients with internal rectal intussusception. INTERVENTIONS: Resection rectopexy by an open (n = 13) or laparoscopically-assisted (n = 9) technique. MAIN OUTCOME MEASURES: Symptomatic outcome, patients' satisfaction, and morbidity. Outcome was based mainly on the validated KESS score, which covers 10 symptoms included in the definiton of constipation. RESULTS: There was a significant reduction in all 10 symptoms. Two patients complained of incontinence which improved after operation. The number of patients with constipation was reduced from 20 to 8 (p = 0.000) and none became constipated. Mean (95% CI) colonic transit times before and after operation in 10 patients with constipation were 5.3 (4.1 to 6.4) and 4.0 (2.6 to 5.4) days (p = 0.083). Seven of these 10 patients had a reduction of both transit time and constipation score. Six patients had complications after open operations. These included one damaged ureter, reoperations for bleeding, incomplete intestinal obstruction, and 2 wound infections. CONCLUSION: Rectopexy with sigmoid resection resulted in improvement in symptoms, including constipation and feeling of incomplete rectal evacuation, and acceptable morbidity.

A national strategic change in treatment policy for rectal cancer--implementation of total mesorectal excision as routine treatment in Norway. A national audit.

INTRODUCTION: Rectal cancer surgery has been characterized by a high incidence of local recurrence, an occurrence which influences survival negatively. In Norway there was a growing recognition that local recurrence rates were related to surgeon performance and that surgeons applying a standardized surgical technique in the form of total mesorectal excision could achieve better results. This contrasts with the prevailing argument voiced by many opinion leaders that local recurrence rates and possibly survival rates can only be improved by adjuvant or neoadjuvant treatment strategies. The Norwegian Rectal Cancer Project-initiated in 1993-aimed at improving the outcome of patients with rectal cancer by implementing total mesorectal excision as the standard rectal resection technique. METHODS: This observational national cohort study covers all new patients (3,319) with rectal cancer from a population of 4.5 million treated between November 1993 and August 1997. The main outcome measures were local recurrence, survival, and postoperative mortality and morbidity rates. The technique of total mesorectal excision was compared with conventional surgery. RESULTS: The proportion of patients undergoing total mesorectal excision was 78 percent in 1994, increasing to 92 percent in 1997. The observed local recurrence rate for patients undergoing a curative resection was 6 percent in the group treated by total mesorectal excision and 12 percent in the conventional surgery group. Four-year survival rate was 73 percent after total mesorectal excision and 60 percent after conventional surgery. Postoperative mortality rate was 3 percent and the anastomotic dehiscence rate was 10 percent. Radiotherapy was given to 5 percent and chemotherapy to 3 percent of the patients in the curative resection group. CONCLUSION: A refinement of the surgical resection technique for rectal cancer can be achieved on a national level, the technique of total mesorectal excision can be widely distributed, and surgery alone can give good results.

Is there any correlation between objective anal testing, rupture grade, and bowel symptoms after primary repair of obstetric anal sphincter rupture?: an observational cohort study.

PURPOSE: The purpose of this study was to investigate the relationships between the grade of anal sphincter rupture, anal sphincter defect, manometry variables, and anal incontinence. METHODS: A total of 132 females with first-time obstetric sphincter rupture were evaluated by transanal ultrasound, manometry, and scoring of bowel symptoms five months after delivery. RESULTS: Anal sphincter rupture and transanal ultrasound grade correlated with each other ( rs= 0.427, P= 0.001). Both rupture and transanal ultrasound grade correlated with soiling grade ( rs= 0.2, P= 0.03 for both), but in a multiple regression analysis, only transanal ultrasound grade was significant ( P= 0.001) as an independent variable. Anal incontinence score correlated with all the manometry variables, but in a multiple regression analysis, only squeeze pressure was significant ( P= 0.001, beta = -0.4) as an independent variable. Both anal sphincter rupture and transanal ultrasound grade were correlated with manometry variables, but only transanal ultrasound grade was significant as an independent variable after multiple regression analysis. The frequency of transanal ultrasound-verified extensive defect of anal sphincter was higher in rupture Grade 3B (25; 95 percent confidence interval, 12-38 percent) and Grade 4 (45; 95 percent confidence interval, 24-66 percent) than in Grade 3A (2.8; 95 percent confidence interval, -1 to -6.6 percent).(s) (s)CONCLUSION Manometry variables are significantly lower in incontinent females than in continent females, and the Wexner incontinence score was correlated with manometry variables. Both anal sphincter rupture and transanal ultrasound grade correlated with soiling grade and with manometry variables, but in both cases only the transanal ultrasound grade was a significant independent variable.

Do occult anal sphincter injuries, vector volume manometry and delivery variables have any predictive value for bowel symptoms after first time vaginal delivery without third and fourth degree rupture? A prospective study.

BACKGROUND: The aim of this study was to determine whether there exists a correlation between anal incontinence, occult sphincter injuries, anal manometry values, and delivery variables in primiparous women after first time vaginal delivery. METHODS: Eighty-six primigravida women were recruited for this study. Transanal ultrasonography (TAUS) and vector volume manometry (VVM) was performed and bowel symptoms were recorded at 25 weeks of pregnancy and 5 months after labor. Incontinent women at 5 months after vaginal delivery were interviewed again at 12 months. RESULTS: Nineteen women (25%) experienced flatus incontinence postpartum. After 12 months, only one-third of the women were still incontinent. Fourteen women (19%) showed abnormal TAUS of the anal sphincter. Of the delivery variables, only baby head circumference was significantly associated with flatus incontinence (p = 0.01). There was no correlation between flatus incontinence or delivery variables and anal sphincter injuries; VVM values were not associated with either anal sphincter injuries or flatus incontinence at 5 months, but VVM values were negatively associated with flatus incontinence at 12 months after labor. CONCLUSIONS: At 5 months after labor, flatus incontinence is relatively common, and is not associated with reduced VVM values. Two-thirds of women recover from flatus incontinence during the first year. Women who had flatus incontinence persisting for a minimum of 1 year had reduced VVM values. Anal sphincter injuries as seen by TAUS are not associated with either VVM values or any delivery variable. Baby head circumference is the only delivery variable significantly associated with flatus incontinence.
