Anorectal Malformations : Long-term outcome and aspects of secondary treatment
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Faecal incontinence (FI) is defined as the inability to control bowel movements. The causes of FI are many and diverse. One of the more uncommon reasons for FI is Anorectal Malformations (ARMs). An ARM is a congenital anomaly that affects somewhere between 1/2500 and 1/5000 live born babies. Many ARM patients have persistent FI. Several different procedures have been utilised to address this issue. This thesis aims to evaluate (1) the long-term outcome in adulthood of ARMs in relation to the modern Krickenbeck classification, and (2) scope for treating FI with transanal injection with dextranomer in non-animal stabilised hyaluronic acid (NASHA/Dx), in patients both with and without ARMs.All patients treated for ARMs in Uppsala up to 1993 were invited to participate in a questionnaire study of quality of life and function. The study included 136 patients and compared them with 136 age- and sex-matched controls. The Krickenbeck classification was found to predict functional outcome, and ARM patients had more problems with incontinence and obstipation, as well as inferior Quality of Life (QoL), compared with controls. Thirty-six patients with FI, owing to causes other than ARMs, were treated with transanal submucous injection of NASHA/Dx. The patients were monitored for two years after treatment. Significant reductions in both their incontinence score and the number of their incontinence episodes were achieved. A significant improvement in QoL was observed in patients who had at least a 75% reduction in incontinence episodes. No serious complications occurred.A prospective study of transanal injection of NASHA/Dx was conducted on seven patients with persistent FI after ARMs. After six months a significant reduction in the number of incontinence episodes was obtained. A significant improvement in QoL was also found. No serious complications occurred.In conclusion, adult patients with ARMs have inferior outcome of anorectal function and QoL compared with controls. NASHA/Dx is effective and appears to be safe in treating FI in general. This effect seems to be the same in selected patients with persistent FI after ARMs.

- Background: Many women suffer from sexual problems after anal sphincter tears due to obstetric trauma. Aim: The study aimed to assess changes in sexual function after anal sphincter repair. Methods: The study was a non-randomized prospective observational cohort study. Inclusion of the study was done at the University Hospital, Uppsala, Sweden, between 2002 and 2007. Thirty-nine consecutive female patients admitted for anal sphincter repair were invited to the study. Twenty patients accepted and were included, four were lost to follow up and one was unevaluable (due to the formation of a stoma) leaving a study group of 15 patients. The patients were assessed with questionnaires before surgery and at three and 12 months after surgery. Outcomes: Change in reported sexual activity and dyspareunia. Results: Before surgery, 12/15 patients reported that their sexual life was impaired due to anal incontinence. The corresponding figure at 12 months was 9/15 (p = 0.43). Three patients remained sexually inactive throughout the study, five patients increased their sexual activity and one had decreased activity. Out of the 12 who were active, four stated dyspareunia at baseline, and only one reported dyspareunia at 12 months. The mean Miller incontinence scores at baseline and 12 months were 10.1 and 8.7, respectively. The change in incontinence score did not differ between those with decreased, stable or increased sexual activity. However, there was a definite correlation (r = 0.54 - 0.60, p < 0.05) between change in sexual function and deferring time for stool. Clinical Implications: Operative management of anal sphincter tears alone is not curative for sexual problems due to anal incontinence but can be a part of the treatment. Strengths and Limitations: The study is a prospective study of sexual function. The limitations are that the questionnaires were not validated due to lack of such questionnaires at the time of the study and that the study population is quite small. Conclusion: Patients with a sphincter injury and fecal incontinence often have an impaired sexual function. Increased deferring time for stools after surgery increases the likelihood of improved sexual function.

- Purpose: Pyloromyotomy for pyloric stenosis is one of the more common surgical procedures performed on infants. The long-term effects of the procedure are however unclear. The purpose of this study was to study the effects into adult life, compare them with controls and to see if there is a need for structured follow up of patients.Methods: Of the 101 patients operated for pyloric stenosis between 1972 and 1974 at our tertiary referral center 91 could be traced. They were all invited to participate in the study and were sent validated ques-tionnaires (PAGI-SYM, GIQLI) as well as a study-specific questionnaire examining the use of antacid drugs, incidence of gastroscopy and abdominal surgery. Sixty patients responded (66%, mean age 45 years, 46 male) and were included. Thereafter, 600 age and sex-matched controls were sent the same question-naires. 132 responded (22%, 90 male) and were includes as controls.Results: No significant differences could be found in any of the examined parameters when looking at the whole material or the male patients. Female patients had higher PAGI-SYM-scores for post prandial fullness (mean 1.11 vs 0.43, P = 0.035) and heartburn (mean 0.59 vs 0.14, P = 0.043) when compared to controls.Conclusions: The present study shows that most patients operated for pyloric stenosis during infancy experience no negative effects into adulthood. The finding in the female patient group is interesting but is unlikely to have any clinical implications. The results from this study strongly implicate that there is no need for follow up of patients into adulthood.Level of evidence: Level III.

- 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 %.

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background/PurposeDuring the last decades injectable bulking therapy has emerged as a promising treatment option for fecal incontinence (FI). Very little has been published on the use of injectable bulking therapy on patients with persistent FI after anorectal malformations (ARM). This study aimed to evaluate non-animal stabilized hyaluronic acid with dextranomer (NASHA/Dx) for the treatment of adult ARM patients with persistent FI.MethodsSeven adult patients with persistent FI after ARM were treated with perianal submucuos injection of NASHA/Dx. They were evaluated preoperatively and at three and six months after treatment with a validated bowel function questionnaire and a two-week bowel diary as well as FIQL and SF-36 quality of life questionnaires.ResultsBefore treatment mean Miller incontinence score was 13,7 and the mean number of incontinence episodes over two weeks was 20,7. At 6 months after treatment the corresponding figures were 10,7 (P=0,1088) and 5,3 (P=0,0180) respectively. No significant changes could be found in either FIQL or SF-36 scores. No serious adverse events occurred during the study.ConclusionsNASHA/Dx is a promising treatment option for selected adult patients with persistent FI after ARM. Long-term follow up of larger patient series as well as studies on patients in adolescence are needed.

- Background/Purpose: Injectable bulking therapy has emerged as a treatment for fecal incontinence (IT, however there are no studies including adult patients with anorectal malformations (ARM). This study aimed to evaluate non-animal stabilized hyaluronic add with dextranomer (NASHA/Dx) for the treatment of adult ARM patients with persistent FI.Methods: Seven adults with ARM and incontinence to loose stool at least once weekly and without rectal or mucosal prolapse were treated with anal NASHA/Dx injection. They were evaluated preoperatively, at 6 and 18 months with a bowel function questionnaire and a 2-week bowel diary as well as FTQL and SF-36 quality of life questionnaires.Results: Before treatment, the mean number of incontinence episodes over 2 weeks was 20.7 (median 16, range 8-52). At 6 months, the corresponding figures were 53 (median 4, range 0-19, p = 0.018), and at 18 months the figures were 4.3 (median 2, range 1-20,p = 0.018). An improved physical function in SF-36 from 74.3 at baseline to 86.4 at 6 months was noted (p = 0.04). No serious adverse events occurred.Conclusions: NASHA/Dx is a promising treatment option for selected adult patients with persistent Ft after ARM. Longer follow up of larger patient series and studies on patients in adolescence is needed.

Tidskriftsartikel (refereegranskat)abstract
- 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.

- Background/purposeKnowledge 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.MethodsOf 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.ResultsThe 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.ConclusionsThe 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.

- Background and objective:In 2014 we introduced percutaneous internal ring suture as an alternative to open surgery for the treatment of inguinal hernia. This study aims to evaluate the introduction of the procedure at our institution.Methods:In total, 100 consecutive patients operated with percutaneous internal ring suture were compared with 100 consecutive patients operated with open surgery. The patients were operated from August 2014 until November 2017. Patient demographics, clinical history, operative time, time in theater, and postoperative complications were extracted from charts.Results:The mean operative time for percutaneous internal ring suture was 26.54 min and for open surgery 39.94 min, P < 0.0001. The total mean operative theater time for percutaneous internal ring suture was 108.95 min and for open surgery 118.4 min, P = 0.0343. During follow-up, two percutaneous internal ring sutures were operated for recurrent hernia. In the open surgery-group, three patients were operated for recurrent hernia, three for secondary testicular retention, and three for metachronous contralateral hernia.Conclusions:Even when established as a new technique, the percutaneous internal ring suture procedure is safe and results in shorter operative time and shorter theater time compared to open surgery.

- 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.
