Antegrade continence enema in the treatment of obstructed defaecation with or without faecal incontinence.

BACKGROUND: Obstructed defaecation and faecal incontinence are complex functional disorders that pose management challenges. In recent times, the antegrade continence enema (ACE) has been tried both as a primary procedure and as a final resort to avoid a colostomy in patients with a variety of functional problems. The purpose of this study was to evaluate the role of the ACE procedure as a treatment option for adult patients suffering from obstructed defaecation with or without faecal incontinence, some of whom also had slow transit constipation. METHODS: Twenty female patients underwent ACE as an appendicostomy (65%) or caecostomy (35%). The median age was 44 years (range, 20-65 years). The indications were obstructed defaecation with faecal incontinence (65%) and obstructed defaecation alone (35%). Fifteen of these patients were followed for 3-51 months (median, 6 months). Cleveland continence score, bowel score and quality of life score were recorded pre- and postoperatively along with post-procedure complications. RESULTS: Thirteen (65%) patients were satisfied with the outcome and recorded improvement in their scores while two (10%) remained the same and one (5%) was worse. This latter woman and another patient stopped using their ACE, whilst follow-up data was unavailable for three patients. Minor wound infections were noted in nine patients (45%), of whom one needed drainage of an abscess; the rest settled with antibiotics and dressings. Bowel and Cleveland continence scores improved postoperatively (p<0.001 and p=0.001, respectively) but SF36 scores did not. To date, no patient has had a colostomy following an ACE procedure. CONCLUSIONS: Colostomies can be avoided in patients with obstructed defaecation. There is, however, a need to minimise wound infections which seem to be the most troublesome complication.

Retrospective comparison of mesh and sutured repair for adult umbilical hernias.

Adult umbilical and paraumbilical hernia repair is associated with a high recurrence rate of 10-30%. Mesh repair has been reported to be associated with low recurrence rates. This study aims to compare sutured repair with prosthetic mesh repair to evaluate recurrence and infection rates. A retrospective study was conducted over an 8-year period including all the umbilical and paraumbilical hernia repairs performed by one consultant surgeon. The hernias were repaired using interrupted suture, Mayo overlap, flat mesh and mesh plug techniques. The study was based on case-note review, telephone and postal questionnaire survey. A total of 100 patients were studied, of which 70 had paraumbilical hernias, 28 had umbilical hernias and 2 had both types of hernia. Median age was 56 years (range 19-90 years). A total of 61 patients had suture repair (50 interrupted suture repair, 11 Mayo) and 39 had prosthetic mesh repair (33 mesh plug, 6 flat mesh). The median body mass index (BMI) was 31.2 (range 23.4-44.5) in the suture repair group and 33.3 (range 24.1-59.1) in the mesh group, with no significant statistical difference in BMI between the two groups (P>0.05). Median follow-up was 4.5 years (range 1-8 years). Recurrence rates for the suture and mesh repair groups were 11.5 and 0%, respectively (P=0.007). Infection rates for the suture and mesh repair groups were 11.5 and 0%, respectively (P=0.007). Our data suggest that prosthetic mesh repair is ideal for managing primary and recurrent umbilical hernias in both obese and non-obese patients.

Are obstetric risk factors and bowel symptoms associated with defaecographic and manometric abnormalities in women awaiting hysterectomy?

Abdominal hysterectomy has been shown to affect anorectal function. These studies are either population-based or have been performed retrospectively. It is not clear from the literature whether those subjects awaiting hysterectomy already have an element of pelvic floor failure and which may be related to obstetric risk factors. A complete anorectal assessment was performed in a group of women awaiting hysterectomy who did not volunteer any bowel symptoms. The patients studied were part of an ongoing study of the functional effects of abdominal hysterectomy. All had their anorectal function assessed before their respective surgery by a questionnaire (functional bowel score), Cleveland continence score, endoanal ultrasound (U/S), anal manometry, defaecatory proctogram and colonic transit. A detailed obstetric history, which included risk factors such as parity, type of delivery, duration of labour and elevated birth weight, were also recorded. Patients with previous bowel disease, bowel surgery and anal sphincter repair were excluded. There were 39 subjects with a median age of 43 years (range 31-65), respectively. Thirty-three rectocoeles and 22 intussusceptions were demonstrated. Two had poor puborectalis function, while five had cough incontinence. Two women had abnormal colonic transit. Thirteen had abnormal anal manometry. Endoanal ultrasound was normal in all patients. None of the obstetric risk factors were associated with rectocoele, intussusception or abnormal anal manometry. Low squeeze pressure was associated significantly with more bowel symptoms (P=0.03). However, rectocoele, intussusception, abnormal colonic transit, abnormal resting anal pressure and maximal tolerated volume were not statistically significantly associated with bowel symptoms. The majority of female subjects who were awaiting hysterectomy had physiological and proctographic abnormalities consistent with pelvic floor failure. Obstetric risk factors were not associated with rectocoele, intussusception, abnormal colonic transit and anal manometry in this cohort of patients. Similarly, the majority of proctographic abnormalities were not associated with bowel symptoms. However, a trend was noted associating bowel symptoms with manometric abnormalities.

A prospective audit of stomas--analysis of risk factors and complications and their management.

AIM: To prospectively audit stomas and to determine the nature and rate of complications and their relationship with various risk factors and their management. MATERIALS AND METHODS: The study was performed prospectively on 97 consecutive patients who had stomas formed between January 2000 to August 2000. Patients were followed up for one year. Risk factors including age, body mass index (BMI), preoperative siting, contour of the abdominal wall, smoking, grade of operating surgeon, emergency or elective procedure, diabetes, type of stoma and suture material used were noted. The type of surgery, and indications for surgery were also recorded. The complications were documented by two qualified stoma nurses and a photographic record taken. Statistical analysis comprising both univariate and multivariate methods, was performed by SPSS 10. RESULTS: The mean age was 65 years (standard deviation 16.01, range 16-99) and mean body mass index was 24.5 (standard deviation 4.66, range 15-37). Forty-nine of 97 (50.5%) stomas developed one or more complications. Twenty-three patients experienced retraction, 18 had stomas sited in a skin crease, 16 had early and 12 had late skin excoriation, 12 had detachments and a further 12 had parastomal hernia. Eleven further stoma complications were noted including prolapse, necrosis, ischaemia and sloughing. None of the risk factors achieved statistical significance when analysed against the overall complication rate. However, when the risk factors were analysed against individual complications using univariate logistic regression, a high body mass index was associated with more retractions (P = 0.003), early skin excoriation (P = 0.036) and poor siting (stoma in crease) occurred more commonly in emergencies (P = 0.022). Diabetes was associated with late skin excoriation (P = 0.02). Multivariate logistic regressions confirmed an independent association of body mass index, diabetes and emergency surgery with complications. Forty-five of 49 patients who had complications needed some conservative management such as a convexity appliance. Four patients needed refashioning. CONCLUSION: Body mass index, diabetes and emergency surgery were the significant risk factors identified in our study. Overall complications compare favourably with other series. We found that preoperative siting by stoma nurses and the grade of operating surgeon did not affect the outcome.

The rhomboid flap for pilonidal disease.

INTRODUCTION: There have been many surgical techniques described for the treatment of pilonidal sinuses. Recurrent disease causes significant morbidity particularly with time from work. AIM: To assess the rhomboid flap's role in promoting one-stage primary healing in pilonidal disease and to evaluate the morbidity and recurrence. METHODS: Fifty-three patients were prospectively recruited of which 27 had previous multiple abscess formation requiring surgical drainage from their pilonidal disease, although none had acute disease at the time of surgery. By using the transposition flap, we were able to obliterate the natal cleft and therefore the rolling action of the buttocks between the cleft in these patients and thereby remove one of the factors involved in pilonidal disease. Hospital stay, healing time, wound infection, wound breakdown and recurrence were noted. RESULTS: There were 47 males and 6 females with a median age of 28 years (range 16-64 years). Median follow-up was 24 months (range 3-36 months). Post-operative morbidity involved superficial wound infection in 7 (13%) which settled with out-patient dressings. There were four recurrences (7%), two occurred between the flap and the anal canal, and the other two in the flap margin needing intervention. All the patients healed their wounds and the median healing time was 14 days. CONCLUSION: As this condition affects a predominantly young population causing significant time off from work, we feel that the Rhomboid Flap is useful for difficult cases in that it allows early return to full activity and does not necessitate prolonged postoperative care.

The impact of open access flexible sigmoidoscopy: a comparison of two services.

BACKGROUND: Open access flexible sigmoidoscopy (OAFS) is an integral part of colorectal cancer services. This study compares the impact of two types of open-access flexible sigmoidoscopy services on the utilisation of barium enema and tumour-stage migration. METHODS: This was a non-randomised comparison (over two one-year periods, four years apart) of two unselected groups of patients, with different inclusion criteria, in adjacent similarly populated health districts. One offered a nurse practitioner endoscopy service while the other had a doctor-led colorectal clinic. RESULTS: The doctor-led service with its broad inclusion criteria detected more colorectal cancers [13.2% versus 0.7%; OR = 16.05; 2.16-119.2]. Neither nurse practitioner (130 cases) nor doctor-led (262 cases) flexible sigmoidoscopy reduced the total number of barium enemas [Odds Ratio (OR) = 1.16 (95% CI 1.03-1.3)]. However, the doctor-led service did reduce the number of barium enemas requested by general practitioners (from 249 to 152). The total number of colorectal cancers (detected by all available methods) were similar [OR = 0.82 (0.53-1.25)] and both services resulted in a similar tumour-stage migration [OR = 1.39 (0.31-6.23)]. CONCLUSION: Open access flexible sigmoidoscopy services have minimal impact on the utilisation of radiology services. Broader inclusion criteria of doctor-led services produce a higher cancer-yield. Tumour-stage migration may be related to greater awareness of colorectal cancer symptoms rather than to the type of OAFS.
