RESUMO
BACKGROUND: It is unclear whether functional outcomes improve or deteriorate with age following surgery for Hirschsprung's disease. The aim of this cross-sectional study was to determine the long-term functional outcomes and quality of life (QoL) in patients with Hirschsprung's disease. METHODS: Patients with pathologically proven Hirschsprung's disease older than 7 years were included. Patients with a permanent stoma or intellectual disability were excluded. Functional outcomes were assessed according to the Rome IV criteria using the Defaecation and Faecal Continence questionnaire. QoL was assessed by means of the Child Health Questionnaire Child Form 87 or World Health Organization Quality of Life questionnaire 100. Reference data from healthy controls were available for comparison. RESULTS: Of 619 patients invited, 346 (55·9 per cent) responded, with a median age of 18 (range 8-45) years. The prevalence of constipation was comparable in paediatric and adult patients (both 22·0 per cent), and in patients and controls. Compared with controls, adults with Hirschsprung's disease significantly more often experienced straining (50·3 versus 36·1 per cent; P = 0·011) and incomplete evacuation (47·4 versus 27·2 per cent; P < 0·001). The prevalence of faecal incontinence, most commonly soiling, was lower in adults than children with Hirschsprung's disease (16·8 versus 37·6 per cent; P < 0·001), but remained higher than in controls (16·8 versus 6·1 per cent; P = 0·003). Patients with poor functional outcomes scored significantly lower in several QoL domains. CONCLUSION: This study has shown that functional outcomes are better in adults than children, but symptoms of constipation and soiling persist in a substantial group of adults with Hirschsprung's disease. The persistence of defaecation problems is an indication that continuous care is necessary in this specific group of patients.

AIM: Total colonic aganglionosis (TCA) is a severe form of Hirschsprung's disease (HD) associated with a high morbidity. This study assessed long-term functional outcome and quality of life (QoL) of patients with TCA in a national consecutive cohort. METHODS: Surgical and demographic characteristics in the medical records of all patients (n = 53) diagnosed with TCA between 1995 and 2015 were reviewed. Functional outcome of all nonsyndromal patients, aged ≥ 4 years (n = 35), was assessed using a questionnaire and in medical records. Generic and disease-specific QoL were assessed using standardized validated questionnaires. RESULTS: Of 35 patients eligible for follow-up, 18 (51%) responded to the questionnaires. They were aged 4-19 years. A Duhamel procedure was performed in 67% of these patients and a Rehbein procedure was performed in 33%. In the questionnaire, 65% of the patients reported constipation, 47% faecal incontinence and 53% soiling. Moreover, 18% of patients used bowel management (flushing or laxatives) and 29% had an adapted diet only. Children and adolescents with TCA had worse perception of their general health and were more limited by bodily pain and discomfort compared with healthy peers. Their quality of life is influenced most by frequent complaints of diarrhoea and other physical symptoms. CONCLUSION: Children and adolescents with TCA report lower health-related QoL compared with healthy peers, especially in the physical domain. We suggest standardized follow-up and prospective longitudinal future research on functionality and QoL of these patients.

INTRODUCTION: Laparoscopic antireflux surgery (LARS) in children primarily aims to decrease reflux events and reduce reflux symptoms in children with therapy-resistant gastroesophageal reflux disease (GERD). The aim was to objectively assess the effect and efficacy of LARS in pediatric GERD patients and to identify parameters associated with failure of LARS. METHODS: Twenty-five children with GERD [12 males, median age 6 (2-18) years] were included prospectively. Reflux-specific questionnaires, stationary manometry, 24-h multichannel intraluminal impedance pH monitoring (MII-pH monitoring) and a 13C-labeled Na-octanoate breath test were used for clinical assessment before and 3 months after LARS. RESULTS: After LARS, three of 25 patients had persisting/recurrent reflux symptoms (one also had persistent pathological acid exposure on MII-pH monitoring). New-onset dysphagia was present in three patients after LARS. Total acid exposure time (AET) (8.5-0.8 %; p < 0.0001) and total number of reflux episodes (p < 0.001) significantly decreased and lower esophageal sphincter (LES) resting pressure significantly increased (10-24 mmHg, p < 0.0001) after LARS. LES relaxation, peristaltic contractions and gastric emptying time did not change. The total number of reflux episodes on MII-pH monitoring before LARS was a significant predictor for the effect of the procedure on reflux reduction (p < 0.0001). CONCLUSIONS: In children with therapy-resistant GERD, LARS significantly reduces reflux symptoms, total acid exposure time (AET) and number of acidic as well as weakly acidic reflux episodes. LES resting pressure increases after LARS, but esophageal function and gastric emptying are not affected. LARS showed better reflux reduction in children with a higher number of reflux episodes on preoperative MII-pH monitoring.

The repair of cloacal malformations is most often performed using a posterior sagittal anorecto-vagino-urethroplasty (PSARVUP) or total urogenital mobilization (TUM) with or without laparotomy. The aim of this study was to systematically review the frequency and type of postoperative complication seen after cloacal repair as reported in the literature. A systematic literature search was conducted according to preferred reporting items for systematic reviews and meta-analyses guidelines (PRISMA). Eight records were eligible for this study which were qualitatively analyzed according to the Rangel score. Overall complication rates reported in included studies ranged from 0 to 57 %. After meta-analysis of data, postoperative complications were seen in 99 of 327 patients (30 %). The most common reported complications were recurrent or persistent fistula (n = 29, 10 %) and rectal prolapse (n = 27, 10 %). In the PSARVUP group, the complication rate was 40 % and in the TUM group 30 % (p = 0.205). This systematic review shows that postoperative complications after cloacal repair are seen in 30 % of the patients. The complication rates after PSARVUP and TUM were not significantly different. Standardization in reporting of surgical complications would inform further development of surgical approaches. Other techniques aiming to lower postoperative complication rates may also deserve consideration.

The ARM-Net (anorectal malformation network) consortium held a consensus meeting in which the classification of ARM and preoperative workup were evaluated with the aim of improving monitoring of treatment and outcome. The Krickenbeck classification of ARM and preoperative workup suggested by Levitt and Peña, used as a template, were discussed, and a collaborative consensus was achieved. The Krickenbeck classification is appropriate in describing ARM for clinical use. The preoperative workup was slightly modified. In males with a visible fistula, no cross-table lateral X-ray is needed and an anoplasty or (mini-) posterior sagittal anorectoplasty can directly be performed. In females with a small vestibular fistula (Hegar size <5 mm), a primary repair or colostomy is recommended; the repair may be delayed if the fistula admits a Hegar size >5 mm, and in the meantime, gentle painless dilatations can be performed. In both male and female perineal fistula and either a low birth weight (<2,000 g) or severe associated congenital anomalies, prolonged preoperative painless dilatations might be indicated to decrease perioperative morbidity caused by general anesthesia. The Krickenbeck classification is appropriate in describing ARM for clinical use. Some minor modifications to the preoperative workup by Levitt and Peña have been introduced in order to refine terminology and establish a comprehensive preoperative workup.

BACKGROUND: The impact of perioperative care interventions on postreconstructive complications and short-term colorectal outcome in patients with anorectal malformation (ARM) type rectovestibular fistula is unknown. METHODS: An ARM-Net consortium multicenter retrospective cohort study was performed including 165 patients with a rectovestibular fistula. Patient characteristics, perioperative care interventions, timing of reconstruction, postreconstructive complications and the colorectal outcome at one year of follow-up were registered. RESULTS: Overall complications were seen in 26.8% of the patients, of which 41% were regarded major. Differences in presence of enterostomy, timing of reconstruction, mechanical bowel preparation, antibiotic prophylaxis and postoperative feeding regimen had no impact on the occurrence of overall complications. However, mechanical bowel preparation, antibiotic prophylaxis ≥48â¯h and postoperative nil by mouth showed a significant reduction in major complications. The lowest rate of major complications was found in the group having these three interventions combined (5.9%). Multivariate analyses did not show independent significant results of any of the perioperative care interventions owing to center-specific combinations. At one year follow-up, half of the patients experienced constipation and this was significantly higher among those with preoperative mechanical bowel preparation. CONCLUSIONS: Differences in perioperative care interventions do not seem to impact the incidence of overall complications in a large cohort of European rectovestibular fistula-patients. Mechanical bowel preparation, antibiotic prophylaxis ≥48â¯h, and postoperative nil by mouth showed the least major complications. Independency could not be established owing to center-specific combinations of interventions. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: III.

BACKGROUND: In patients with asymptomatic colorectal cancer with irresectable metastatic disease, the optimal treatment strategy remains controversial. Resection of the primary tumor followed by chemotherapy when possible versus systemic chemotherapy followed by resection of the primary tumor when necessary are compared in this systematic review. PATIENTS AND METHODS: Seven studies reported series of patients with asymptomatic stage IV colorectal cancer and compared first-line chemotherapy with surgery for the primary tumor (n = 850 patients). Primary outcome measure was the complication rate related to the primary tumor in situ in patients receiving first-line systemic chemotherapy. RESULTS: When leaving the primary tumor in situ, the mean complications were intestinal obstruction in 13.9% [95% confidence interval (CI) 9.6% to 18.8%] and hemorrhage in only 3.0% (95% CI 0.95% to 6.0%) of the patients. After resection, the overall postoperative morbidity ranged from 18.8% to 47.0%. CONCLUSIONS: For patients with stage IV colorectal cancer, resection of the asymptomatic primary tumor provides only minimal palliative benefit, can give rise to major morbidity and mortality and therefore potentially delays beneficial systemic chemotherapy. When presenting with asymptomatic disease, initial chemotherapy should be started and resection of the primary tumor should be reserved for the small portion of patients who develop major complications from the primary tumor.

BACKGROUND: It is questionable whether elective appendicectomy can effectively reduce persistent or recurrent right lower-quadrant abdominal pain due to chronic or recurrent appendicitis. METHODS: This single-centre double-blind randomized clinical trial studied the effects of elective laparoscopic appendicectomy on pain 6 months after operation in patients with persistent or recurrent lower-quadrant pain. A secondary outcome evaluated was the relationship between clinical response and appendiceal histopathology. The analysis was performed on an intention-to-treat basis. RESULTS: Forty patients were randomized to laparoscopic appendicectomy (18) or laparoscopic inspection only (22). Postoperative pain scores differed significantly between the groups, favouring appendicectomy (P = 0.005). Relative risk calculations indicated that there was a 2.4 (95 per cent confidence interval (c.i.) 1.3 to 4.0) times greater chance of improvement in pain after laparoscopic appendicectomy. The number needed to treat was 2.2 (95 per cent c.i. 1.5 to 6.5). There was no association between postoperative pain scores and histopathology findings. CONCLUSION: Persistent or recurrent lower abdominal pain can be treated by elective appendicectomy with significant pain reduction in properly selected cases. Histopathology may not be abnormal.

A 44-year-old multiple injured patient presented with several fractures including a dislocated, comminuted radial head fracture after a 4 meter fall from a ladder. He was treated with radial head resection. However, at routine follow-up he indicated pain and loss of function of his wrist due to a distal radio-ulnar dislocation with a high position of the ulna, causing loss of pronation and supination. This is also known as the Essex-Lopresti lesion. Operative treatment included reduction and fixation of the distal radio-ulnar joint after resection osteotomy of the distal ulnar shaft according to Sauvé and Kapandji.

PURPOSE: Cloacal malformations are the most complex type of anorectal malformation in females. This study aimed to report quality of life (QoL) of patients with a cloacal malformation for the first time in literature. MATERIALS AND METHODS: Female patients with an anorectal malformation participating in a follow-up program for congenital malformation survivors aged 5 or older were eligible for this study. QoL was assessed with the PedsQL™ 4.0 inventory. Scores of patients with a cloacal malformation (CM) were compared with those of female patients with rectoperineal or rectovestibular fistulas (RP/RV) and with reference data. RESULTS: A total of 59 patients (67% response rate; 13 patients with cloacal malformation) were included, QoL was assessed by patient self-report at median age of 12years (8-13), and by parent proxy-report at median age of 8years (5-12). There were no differences between groups regarding the presence of associated anomalies, with also no differences regarding anomalies in the urinary tract (CM vs. RP/RV=31% vs. 15%, p=0.237). Scores of the cloacal malformations group were similar to those of the comparison group, except the proxy-reported scores on school functioning (60.0 vs. 80.0, p=0.003). Proxy-reported scores of cloacal malformation patients were significantly lower than reference values on total QoL-score, psychosocial health, and emotional and school performance. Patients (irrespective of type of ARM) who suffered from fecal soiling reported significantly lower scores with regard to psychosocial health (71.7 vs. 81.7, p=0.034) and its subscale school performance (65.0 vs. 80.0, p<0.001). QoL-scores reported by cloacal malformation patients did not differ significantly from the reference values of the healthy population. Parents of cloacal malformation patients reported significantly lower total QoL, emotional and school performances, as well as a lower general psychosocial health for their children relative to reference data of healthy children. CONCLUSION: Patients with cloacal malformations and females with less complex anorectal malformations report similar QoL. Parents of cloacal malformation patients report more problems on several psychosocial domains relative to the healthy reference group. To monitor these matters, long-term follow-up protocols should contain multidisciplinary treatment including periodical assessment of psychosocial well-being.

BACKGROUND: Laparoscopic antireflux surgery (LARS) is a well-established treatment option for children with proton pomp inhibitor (PPI)-resistant gastroesophageal reflux disease (GERD). Besides preventing reflux of gastric fluid and solid content, LARS may also impair the ability of the stomach to vent intragastric air (i.e. gastric belching) and induce gas-related complications, such as bloating and/or hyperflatulence. Furthermore, it was previously hypothesized that LARS induces a behavioral type of belching, not originating from the stomach, called supragastric belching. The aim of this study was to objectively evaluate the impact of LARS on gastric (GB) and supragastric belching (SGB) in children with GERD. METHODS: We performed a prospective, Dutch multicenter cohort study including 25 patients (12 males, median age 6 (range 2-18) years) with PPI-resistant GERD who were scheduled for LARS. Twenty-four-hour multichannel intraluminal impedance pH monitoring (MII-pH monitoring) was performed before and 3 months after fundoplication. Impedance pH tracings were analyzed for reflux episodes and GBs and SGBs. KEY RESULTS: LARS reduced acid exposure time from 8.5% (6.0-16.2%) to 0.8% (0.2-2.8%), p < 0.001. The number of GBs also significantly decreased after LARS (59 [43-77] VS 5 [2-12], p < 0.001). The number of air swallows remained unchanged after LARS. SGBs were infrequent before LARS with no change in the number of SGB observed after the procedure. Postoperative belching symptoms were associated with GBs, not with SGBs. CONCLUSION & INFERENCES: LARS significantly reduces the number of GBs in children with GERD, whereas the number of air swallows remains unchanged. Postoperative symptomatic belching is associated with GBs, but not with SGBs. These findings suggest that LARS does not induce the occurrence of SGBs in children, but longer follow-up is required.

PURPOSE: Outcomes of patients with an ARM-type rectovesical fistula are scarcely reported in medical literature. This study evaluates associated congenital anomalies and long-term colorectal and urological outcome in this group of ARM-patients. METHODS: A retrospective Dutch cohort study on patients treated between 1983 and 2014 was performed. Associated congenital anomalies were documented, and colorectal and urological outcome recorded at five and ten years of follow-up. RESULTS: Eighteen patients were included, with a mean follow-up of 10.8years. Associated congenital anomalies were observed in 89% of the patients, 61% considered a VACTERL-association. Total sacral agenesis was present in 17% of our patients. At five and ten years follow-up voluntary bowel movements were described in 80% and 50%, constipation in 80% and 87%, and soiling in 42% and 63% of the patients, respectively. Bowel management was needed in 90% and one patient had a definitive colostomy. PSARP was the surgical reconstructive procedure in 83%. Urological outcome showed 14 patients (81%) to be continent. No kidney transplantations were needed. CONCLUSION: In our national cohort of ARM-patients type rectovesical fistula that included a significant proportion of patients with major sacral anomalies, the vast majority remained reliant on bowel management to be clean after ten years follow-up, despite "modern" PSARP-repair. Continence for urine is achieved in the majority of patients, and end-stage kidney failure is rare.

BACKGROUND: There is a need for better tolerated drugs to normalize bowel function in chronic constipation. Prucalopride is a highly selective, specific, serotonin4 receptor agonist with enterokinetic properties. AIM: To evaluate the effects of prucalopride on bowel function, colonic transit and anorectal function in patients with chronic constipation. METHODS: Twenty-eight patients were enrolled in this double-blind, placebo-controlled, crossover study (prucalopride: 1 mg, n=12; 2 mg, n=16). Patients kept a bowel function diary. Colonic transit times and anorectal function (anal manometry, rectal sensitivity and rectal compliance) were assessed. RESULTS: Prucalopride (1 mg) compared to placebo significantly increased the mean number of spontaneous complete, spontaneous and all bowel movements per week. Prucalopride (1 mg) significantly decreased the percentage of bowel movements with hard/lumpy stools and straining and increased the urge to defecate. Prucalopride (1 and 2 mg) decreased the mean total colonic transit time by 12.0 h (prucalopride 42.8 h vs. placebo 54.8 h; P=0.074). No statistically significant effects were found in any of the anorectal function parameters. Prucalopride was well tolerated. There were no clinically relevant changes in standard safety parameters. CONCLUSIONS: Prucalopride significantly improves stool frequency and consistency, and the urge to defecate, and may decrease colonic transit times in patients with chronic constipation.

Patients with chronic constipation fulfilling the Thompson criteria can show paradoxical sphincter contraction. Aim of this study was to evaluate rectal sensorimotor characteristics in patients with constipation with or without paradoxical sphincter contraction. Thirty female patients with chronic constipation and 22 female controls were investigated with anal manometry and rectal barostat. Paradoxical sphincter contraction was shown with manometry as a paradoxical increase of anal pressure during straining. Visceral sensitivity and compliance were tested by intermittent and continuous pressure-controlled distension. Patients were classified according to their sensations and compliance into normal, hypersensitive, reduced compliant, insensitive or excessive compliant rectum. Postprandial rectal response (PRR) and phasic volume events (PVEs) were registered for 1 h after a 600-kCal meal. Paradoxical sphincter contraction was found in 13 (43%) patients. In these patients, rectal sensitivity scores were higher (P = 0.045) than in patients without paradoxical contractions, but rectal compliance was not different. In 90% of patients an abnormal rectal sensitivity or compliance was found: excessively compliant in 35%, reduced compliant in 10%, hypersensitive in 27% and hyposensitive in 17%. Both patients with constipation (11%; P = 0.042) and controls (25%; P = 0.002) exhibited the presence of a postprandial rectal response. This response was not significantly different between idiopathic constipation, paradoxical sphincter contraction and controls. Patients with rectal hypersensitivity had lower response than other patients (P = 0.04). Patients with constipation had fewer basal PVEs compared controls (P = 0.03). Postprandial PVEs increased in both patients (P = 0.014) and controls (P < 0.001). Postprandial rectal response and PVE were not different in patients with or without paradoxical sphincter contraction. A total of 90% of female patients with idiopathic constipation show an abnormality in rectal sensation or compliance. The postprandial rectal response was comparable between patients with constipation and controls, however, PVEs were diminished. Patients with paradoxical sphincter contraction had higher rectal sensitivity but an unaltered compliance and postprandial rectal response. Future trials should investigate whether the classification of rectal abnormalities in patients with constipation has clinical importance.

Colon transit time measurement with radio-opaque markers is a method of studying the passage of luminal contents throughout the colon. Overall colonic transit time (CTT), as well as segmental transit times [right (RTT), left (LTT) and rectosigmoid (RSTT)], can be calculated. We hypothesize that CTT is influenced by faecal impaction when the rectum is emptied infrequently. The aim of this study is to investigate the effect of bowel cleansing on colonic transit time in patients with chronic constipation. In 25 women (age 41 years; range 20-65 years) with constipation according to Thompson criteria, CTT measurement was performed in an unprepared situation and repeated after cleansing with 4 L of Klean-Prepreg. Ten healthy female volunteers (age 41 years; range 27-57 years) were used as controls. In constipated patients, CTT decreased from a median 70 h (range 10-130 h) to 48 h (5-94 h) in the cleansed state (P < 0.001). A shortening of transit time was found in all three segments. In 10 patients with slow transit (ST) (CTT > 86 h), CTT decreased from 110 h (range 94-130) to 86 (38-94) (P < 0.001). Five of the 10 patients with ST before bowel cleansing had a CTT below 86 h after cleansing. In female controls, uncleansed CTT and RSTT shortened from 39 h (23 to 62) and 17 h (8-29) to 29 h (17-48) and 10 h (0-20) after bowel cleansing (P=0.058 and P=0.046). Colonic intraluminal contents have a substantial effect on colonic transit. In female controls, bowel cleansing shortened rectosigmoid transit. Women with constipation had faster transit in the cleansed state, however, the distribution of markers was not altered. Despite the effect of bowel cleansing on CTT, it seems unnecessary to prepare the bowel in clinical practice because the differentiation of patients between slow transit constipation and outlet obstruction is not changed. However, because in an infrequent defecation pattern, the influence of faecal impaction is considerable, CTT should be applied with care for critical clinical decisions in the treatment of constipation.

INTRODUCTION: Congenital diaphragmatic hernia (CDH) is a congenital life-threatening condition requiring surgical repair in the neonatal period. Minimal access surgery (MAS) is gaining ground on the classical open approach by laparotomy or thoracotomy as it minimizes damage to the abdominal or thoracic wall. Using an open review of the literature, we aimed to determine whether MAS is safe and effective in treating CDH. Furthermore, we provide selection criteria for the optimal surgical approach, laid down in a decision algorithm. METHODS: An online search of MEDLINE was performed (May 2012), followed by a citations search. All study types except case reports describing open and/or MAS repair of Bochdalek CDH were eligible. Primary outcome data, for example, surgical complications and mortality, were recorded, as well as secondary outcome measures, for example, operative time, duration of postoperative ventilation, tolerance of enteral nutrition, and total length of stay (LOS) in hospital. Analysis was performed in accordance with the standards of the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: We identified 15 relevant studies, 5 of them describing MAS only and 10 comparing MAS to open repair of CDH. Numbers of included patients and selection criteria for MAS varied widely. Most studies have methodological limitations, such as the use of retrospective data or historical control groups. ECMO treatment and patch use were more frequent in the open repair group (both p < 0.0001). Recurrence risk seemed to be increased in the MAS group. The need for conversion in MAS series ranged widely, from 3.4 to 75.0%. The risk of general surgical complications did not vary between groups. Mortality seemed to be less in the MAS group. Operative time seemed to be longer in the MAS group. Duration of postoperative ventilation and total LOS appeared to be reduced in this group and patients returned quicker to enteral nutrition. CONCLUSIONS: We demonstrate that MAS for diaphragmatic hernia appears to be safe in terms of complications and mortality. Besides, it is associated with faster postoperative recovery. Growing experience with this technique is expected to lower the recurrence risk and to shorten the operative time. These findings should be interpreted cautiously because of methodological limitations of the studies included. Selection criteria used in various studies are associated with an important risk of selection bias. Nonetheless, these criteria can be used to identify patients who will benefit most from MAS.

BACKGROUND AND AIMS: Evacuation disorders associated with a rectocele can be improved by rectocele repair. This study investigated whether anorectal function tests results change after rectocele repair. PATIENTS AND METHODS: Fourteen patients with 2nd or 3rd degree rectocele and evacuation disorder were treated by posterior colporrhaphy and evaluated pre- and postoperatively (after 8 months, range 3-14) using questionnaires, anal manometry and endosonography, rectal barostat testing, and colonic transit time measurement with radio-opaque markers. Results from female controls were used for comparison. RESULTS: Preoperatively, rectocele patients had high maximal basal sphincter pressures, large sphincter lengths, and low maximal squeeze pressures, with an anal sphincter defect in seven and lower visceral sensitivity scores than in controls. Postprandial rectal responses (more than 10% decrease in postprandial volume after 1 h) were found in 3 of 14 patients compared to 2 of 11 parous and 9 of 11 nulliparous controls. After repair, a rectocele of 2nd degree was found in four patients. Questionnaire scores were significantly decreased for straining, evacuation disorder, manual support, and protrusion. Overall patient satisfaction with the operation scored 8.25 (range 3-10). Defecation frequencies and stool consistencies were unaltered. Anal pressures, rectal compliance-curves, visceral sensitivity, and colonic transit times were unaltered after the rectocele repair. CONCLUSION: Rectocele repair improved complaints of evacuation disorder and protrusion, but defecation frequency and stool consistency were not affected. Anorectal function was unaltered after rectocele repair. Selection of patients for rectocele repair should be performed based on evacuation and protrusion complaints, anorectal function, or colonic transit time measurements have a limited role.
