Abstract [en]

PurposeThe aim of this study was to assess the function and quality of life of Hirschsprung's Disease (HD) beyond adolescence and relate it to matched controls.MethodsAll 203 patients diagnosed with HD at our department from 1961 to 1995 were identified. 21 had died, 43 had unclear diagnosis and 16 could not be traced. The remaining 123 patients were sent bowel function and SF-36 quality of life questionnaires. 69 patients (mean age 37.8, range 22-58, 13 female) responded and were matched with 138 age and sex-matched controls.ResultsFunction: HD-patients had significantly higher number of bowel movements per week, higher incidence of soiling, urgency, permanent stomas, use of laxatives, enemas and loperamide. HD-patients also scored significantly lower in their satisfaction with their bowel function. There was, however, no significant difference in Miller Incontinence score.QOL: HD-patients reported a significantly higher incidence of negative impact by their bowel function on daily life, social interaction and ability to go on vacation. There were no significant differences in SF-36-scores.ConclusionsBowel function has a lifelong negative impact on the lives of patients with HD. This strongly indicates a need for structured follow-up beyond adolescence.

Abstract [en]

Purpose Dynamic graciloplasty (DGP) has been used to treat severe fecal incontinence since the 1980s. Previous studies have shown an inferior outcome in patients with anorectal malformations (ARMs). Our experience has been that DGP has been appreciated by ARM -patients. The objective of the study was to evaluate the long-term outcome of DGP in our patients with ARM compared with patients with other underlying conditions. Materials and Methods Twenty-three patients operated with DGP at our institution from 1996 to 2010 were sent validated bowel function and quality of life questionnaires. Eighteen of 23 responded. Seven had ARM and 11 had other etiologies of fecal incontinence. The mean follow-up time was 11.6 years (range, 5-17). Results Four of 7 of the patients with ARM and 8 of 11 of patients with other etiologies used their implants at follow-up. The Miller incontinence score was slightly higher for patients with ARMs, but they had less constipation and higher Fecal Incontinence Quality of Life (FIQL)- and 36-Item Short Form Health Survey (SF-36) scores. None of the differences were statistically significant. Conclusion This study cannot confirm earlier reports in which DGP has an inferior outcome in patients with ARM. We therefore believe that the procedure should remain a treatment option for selected patients.

Abstract [en]

Purpose: Persistent fecal incontinence beyond childhood is common in ARM patients. The aim of this study was to analyze a consecutive series of adult patients with persistent incontinence, establish the causes, and evaluate whether further treatment could be offered. Methods: Forty-four adult ARM patients with reported incontinence were invited. Eighteen patients (11 males, median age 40.5 years, range 18-50 years) accepted and underwent clinical examination, rectoscopy, and 3D-ultrasound. Five had previously been treated with secondary surgery to improve continence. Results: Seventeen of the 18 patients had abnormal findings at examination. Eight patients had obstruction of the reconstructed anus. Eleven patients had sacral deformities. Nine patients had a defect in the external anal sphincter and nine patients could not contract the sphincter on demand. Five patients had significant prolapse of mucosa. In one patient, the neoanus was totally misplaced, one patient had a rectovaginal fistula, and one patient had short bowel syndrome due to several small bowel resections. Ten patients were offered conservative and five surgical treatment. Conclusions: This case series of adults shows that a majority of the patients can be offered further treatment. This indicates a need for structured follow-up of ARM patients into adulthood.

Background/purpose

Knowledge about the functional outcome in adults with anorectal malformations is essential to organize structured transition to adult care for this patient group. The aim of this study was to investigate the functional outcome and quality of life in adults with anorectal malformations characterized according to the Krickenbeck classification.

Methods

Of 256 patients diagnosed with anorectal malformations at our institution in 1961–1993, 203 patients could be traced and were invited to participate in the study. One hundred and thirty-six patients replied (67%) and were compared with one hundred and thirty-six population based sex and age-matched controls. Patients and controls were evaluated with both a validated questionnaire as well as a study-specific questionnaire to assess bowel function. SF-36 was used for quality of life. Outcome in nine incontinence-related parameters, 10 constipation-related, 6 urogenital function-related, and 13 quality of life parameters were assessed in the patients and compared to the outcome of controls as well as to the type of anorectal malformations according to the Krickenbeck classification.

Results

The ARM-patients had an inferior outcome (P < 0.05) for all incontinence parameters, 8 of 10 parameters for constipation, 2 of 6 for urogenital function and 7 of 13 quality of life parameters. Patients with rectobulbar and vestibular fistulas had the worst statistical outcome but patients with cloaca and rectoprostatic/bladder-neck fistula had worse outcome in absolute numbers. Forty-four patients (32%) reported incontinence of stool at least once a week and 16 (12%) had a permanent colostomy.

Conclusions

The functional outcome and quality of life in adults with anorectal malformations are closely related to the type of malformation. A large proportion of the patients have persistent fecal incontinence, constipation and sexual problems that have a negative influence on their quality of life. Structured multidisciplinary follow-up of adults with anorectal malformations by pediatric and colorectal surgeons, as well as urologists and gynecologists is therefore advocated.

Abstract [en]

Background and Aims: Hirschsprung's disease (HSCR) is treated surgically. There is a risk for faecal incontinence and constipation postoperatively. The long-term bowel functional outcome in adults and quality of life are sparsely studied. The aim of this study was to assess bowel function and quality of life in patients who had undergone surgery for HSCR during childhood. Methods: All patients treated between 1969 and 1994 at St. Goran's Children's Hospital in Stockholm were invited to participate in the study. After consent, the patients received questionnaires containing general questions, validated questions on bowel function, questions about urinary function, SF-36 health survey (SF-36) and the Gastrointestinal Quality of Life Index (GIQLI). Clinical data were extracted from the case records. Controls matched for sex and age were randomly selected from the National Swedish Population Register. Results: 48 of 60 (80%) invited patients responded to the questionnaires. Nine patients were excluded since the HSCR diagnosis could not be confirmed. The median age of the included patients was 28 (20-43) years. Most patients had undergone Soave's operation (73.4%) and two patients had a stoma at the time of follow-up. The bowel function was impaired in the HSCR group compared to controls, especially problems with flatulence, need to strain at defecation and several defecations for emptying. Patients in the HSCR group also had significantly more problems with faecal incontinence than controls. Quality of life according to SF-36 did not differ significantly between patients and controls, but the GIQLI score showed a significantly worse outcome in the HSCR group compared to the controls. Conclusion: General quality of life in adults treated for HSCR during childhood is comparable to controls. However, they have impaired bowel function and gastrointestinal quality of life.

Abstract [en]

Laparoscopic gastrostomy (LAPG) has gained popularity in children. The aim of this study was to compare the outcome of LAPG versus open gastrostomy (OG) in children with focus on complications, operative times and postoperative length of stay. Retrospective study of children who had gastrostomies inserted at our tertiary Pediatric Surgery Center from 2000 until 2013. The indications for a gastrostomy were an anticipated need for enteral support for at least 6 months. Totally 243 children were included in the study, 83 with LAPG and 160 with OG. We found a significant difference in postoperative length of stay, 3 days in the LAPG group versus 4 days in the OG group but no difference in a sub-group analysis from 2010 to 2013 when both techniques were used. There was no difference in median operative time or complications rates. Granuloma was the dominating complication in both groups. These two feeding-access techniques are comparable regarding complications, operative times and postoperative length of stay. The choice of surgical method should be individualized based on the patient's characteristics and the experience of the surgeon. The favorable results with LAPG in adults are not necessarily transferable to children since there are physiological and anatomical differences.

Abstract [en]

Background/purpose: The short-term outcome of posterior sagittal anorectoplasty (PSARP) procedure has been reported to be better than after abdominoperineal or abdominosacroperineal (AP) procedures. This study aimed to investigate the long-term functional outcome and quality of life after PSARP in adulthood and compare with the outcome after AP procedures. Methods: Twenty-four patients operated with PSARP at the Department of Pediatric Surgery, Uppsala, Sweden, from 1984 to 1993 were identified. They were compared with 20 patients that underwent AP pull-through procedures from 1974 to 1983. The patients were sent validated bowel function and quality of life (SF-36) questionnaires. Sixteen PSARP (median age 21, five females) patients and fourteen AP patients (seven abdominosacroperineal and seven abdominoperineal pull-throughs, median age 32, seven females) responded and were included in the study. Results: The median Miller incontinence score was 1 (range 0-13) in the PSARP group and 10 (range 3-16) in the pull-through group (P = 0.0042). The use of underwear protection and oral loperamide was significantly less frequent in the PSARP group (P = 0.0096 and 0.0021 respectively). The SF-36 scores of Vitality, Mental health and Mental Cluster Scale were higher in the PSARP group (P = 0.0291, 0.0500, 0.0421 respectively). Conclusions: PSARP results in superior bowel function and better quality of life in adulthood compared with AP procedures for the repair of anorectal malformations.

Abstract [en]

BACKGROUND:

Stabilized non-animal hyaluronic acid/dextranomer (NASHA® Dx) gel as injectable bulking therapy has been shown to decrease symptoms of faecal incontinence, but the durability of treatment and effects and influence on quality of life (QoL) is not known. The aim of this study was to assess the effects on continence and QoL and to evaluate the relationship between QoL and efficacy up to 2 years after treatment.

METHODS:

Thirty-four patients (5 males, mean age 61, range 34-80) were injected with 4 × 1 ml NASHA Dx in the submucosal layer. The patients were followed for 2 years with registration of incontinence episodes, bowel function and QoL questionnaires.

RESULTS:

Twenty-six patients reported sustained improvement after 24 months. The median number of incontinence episodes before treatment was 22 and decreased to 10 at 12 months (P = 0.0004) and to 7 at 24 months (P = 0.0026). The corresponding Miller incontinence scores were 14, 11 (P = 0.0078) and 10.5 (P = 0.0003), respectively. There was a clear correlation between the decrease in the number of leak episodes and the increase in the SF-36 Physical Function score but only patients with more than 75 % improvement in the number of incontinence episodes had a significant improvement in QoL at 24 months.

CONCLUSIONS:

Anorectal injection of NASHA Dx gel induces improvement of incontinence symptoms for at least 2 years. The treatment has a potential to improve QoL. A 75 % decrease in incontinence episodes may be a more accurate threshold to indicate a successful incontinence treatment than the more commonly used 50 %.

Abstract [en]

PURPOSE: Patients with high anorectal anomalies are often incontinent after reconstruction, particularly with the older forms of surgical treatment, that is, anorectal pull-through or Stephen's operations. In 1974, a new treatment for anal incontinence in children was introduced at the Akademiska Hospital: free autogenous muscle transplantation (FAMT) to the perirectal area. All the patients receiving FAMT were totally incontinent before the procedure and had no rectal sensitivity. The aim of this study was to evaluate the long-term functional outcome of this procedure. METHODS: Twenty-two patients (17 males) operated on with FAMT below the age of 15 years were identified through records. One of the patients had died, and 2 were not available for follow-up. The remaining 19 were sent a validated bowel function questionnaire, and 15 (78.9%) of 19 patients responded (12 males). These 15 patients were compared with 15 patients with the same sex, age, and a similar malformation from our patient database. RESULTS: At follow-up, after an average of 30 years postoperatively, 2 of 15 patients with FAMT had a stoma compared with 3 of 15 in the control group. The Miller incontinence score had a mean of 6.2 (median, 6; range, 0-15) in the FAMT group and 3.7 (median, 4; range, 0-12) in the control group. All patients in both groups could sense stool, and 11 of 13 patients in the FAMT group could distinguish between feces and flatus. CONCLUSIONS: The patients with FAMT had a slightly inferior anorectal function compared with the controls. Considering they were all totally incontinent before FAMT, we conclude that FAMT has an acceptable effect 30 years postoperatively. Therefore, we find that FAMT could be an alternative for anorectal malformation patients who are totally incontinent.

Abstract [en]

PURPOSE: NASHA Dx gel has been used extensively for treatments in the field of urology. This study was performed to evaluate NASHA Dx gel as an injectable anal canal implant for the treatment of fecal incontinence. METHODS: Thirty-four patients (5 males, 29 females; median age, 61 years; range, 34 to 80) were injected with 4 x 1 ml of NASHA Dx gel, just above the dentate line in the submucosal layer. The primary end point was change in the number of incontinence episodes and a treatment response was defined as a 50 percent reduction compared with pretreatment. All patients were followed up at 3, 6, and 12 months. RESULTS: The median number of incontinence episodes during four weeks was 22 (range, 2 to 77) before treatment, at 6 months it was 9 (range, 0 to 46), and at 12 months it was 10 (range, 0 to 70, P = 0.004). Fifteen patients (44 percent) were responders at 6 months, compared with 19 (56 percent) at 12 months. No long-term side effects or serious adverse events were reported. CONCLUSIONS: Submucosal injection of NASHA Dx gel is an effective treatment for fecal incontinence. The effect is sustained for at least 12 months. The treatment is associated with low morbidity.
