RESUMEN
BACKGROUND: Endorectal advancement flap repair is often performed for the treatment of cryptoglandular transsphincteric fistulas. However, this procedure fails in approximately 1 of 4 patients. Based on its supposed healing properties, platelet-rich plasma might enhance the outcome of this procedure. OBJECTIVE: To evaluate and compare the short-term and long-term outcomes after endorectal advancement flap repair with and without platelet-rich plasma injection in patients with a cryptoglandular transsphincteric fistula. DESIGN: Retrospective cohort study. SETTING: Tertiary referral hospital for proctology in the Netherlands. PATIENTS: Consecutive patients with a cryptoglandular transsphincteric fistula. Inverse propensity score-weighted comparison was used to adjust for confounding and selection bias. INTERVENTIONS: Endorectal advancement flap repair with and without platelet-rich plasma injection. MAIN OUTCOME MEASURES: Clinical fistula closure within 1 year without need for a reintervention (primary healing), clinical fistula closure within 1 year corrected for reinterventions (secondary healing), overall fistula healing within 1 year, and long-term outcomes assessed by a questionnaire. RESULTS: In total, 219 patients underwent an endorectal advancement flap repair. In 88 patients (40.2%), platelet-rich plasma was injected. No significant difference was observed in primary healing (67.0% vs 69.5%, p = 0.71), secondary healing (37.5% vs 43.5%, p = 0.60), or overall healing (73.9% vs 77.1%, p = 0.58) between patients treated with and without platelet-rich plasma injection. Long-term follow-up was available in 67.1% of the patients with a mean follow-up of 6.8 years (SD: 3.7 years). Among all patients who reached fistula healing, whether primary or secondary, within 1 year and had available long-term follow-up data, recurrence rates were also not significantly different (6.3% vs 2.9%, p = 0.37). Propensity score-weighted analysis showed that patients treated with a platelet-rich plasma injection were not more likely to achieve primary healing (OR 1.0; 95% CI, 0.5-1.9), secondary healing (OR 1.1; 95% CI, 0.2-3.2), overall healing (OR 0.9; 95% CI, 0.5-1.7), or recurrence at long-term follow-up (OR 1.1; 95% CI, 0.4-18.8) compared with patients without platelet-rich plasma injection. LIMITATIONS: Retrospective design, lack of postoperative imaging, and assessment of long-term follow-up using a questionnaire. CONCLUSION: Addition of platelet-rich plasma injection does not improve the short-term and long-term outcomes of endorectal advancement flap repair in patients with a cryptoglandular transsphincteric fistula treated in a tertiary referral center.

ADICIN DE PLASMA RICO EN PLAQUETAS A LA REPARACIN DEL COLGAJO DE AVANCE ENDORRECTAL NO MEJORA LA CURACIN DE LAS FSTULAS TRANSESFINTERIANAS CRIPTOGLANDULARES: ANTECEDENTES:La reparación con colgajo de avance endorrectal a menudo se realiza para el tratamiento de fístulas transesfinterianas criptoglandulares. Sin embargo, este procedimiento falla en aproximadamente uno de cada cuatro pacientes. Basándose en sus supuestas propiedades curativas, el plasma rico en plaquetas (PRP) podría mejorar el resultado de este procedimiento.OBJETIVO:Evaluar y comparar los resultados a corto y largo plazo después de la reparación con colgajo de avance endorrectal con y sin inyección de PRP en pacientes con una fístula transesfintérica criptoglandular.DISEÑO:Estudio de cohorte retrospectivo.ÁMBITO:Hospital terciario de referencia para proctología en los Países Bajos.PACIENTES:Pacientes consecutivos con fístula transesfintérica criptoglandular. Se utilizó una comparación ponderada por puntuación de propensión inversa para ajustar los factores de confusión y el sesgo de selección.INTERVENCIONES:Reparación del colgajo de avance endorrectal con y sin inyección de PRP.PRINCIPALES MEDIDAS DE VALORACIÓN:Cierre clínico de la fístula dentro de un año sin necesidad de reintervención (cicatrización primaria), cierre clínico de la fístula dentro de un año corregido por reintervenciones (cicatrización secundaria), curación general de la fístula dentro de un año y resultados a largo plazo evaluados mediante un cuestionario.RESULTADOS:En total, 219 pacientes se sometieron a una reparación con colgajo de avance endorrectal. En 88 pacientes (40,2%) se inyectó PRP. No se observaron diferencias significativas en la curación primaria (67,0% frente a 69,5%, p = 0,71), curación secundaria (37,5% frente a 43,5%, p = 0,60) y curación general (73,9% frente a 77,1%, p = 0,58).) entre pacientes con y sin inyección de PRP, respectivamente. El seguimiento a largo plazo estuvo disponible en el 67,1% de los pacientes con un seguimiento medio de 6,8 años (desviación estándar: 3,7 años). Dentro de todos los pacientes que alcanzaron la curación de la fístula, tanto primaria como secundaria, dentro de un año y tenían datos de seguimiento a largo plazo disponibles, las tasas de recurrencia tampoco fueron significativamente diferentes (6,3% vs. 2,9%, p = 0,37). El análisis ponderado por puntuación de propensión mostró que los pacientes tratados con una inyección de PRP no tenían más probabilidades de lograr la curación primaria (odds ratio [OR] 1,0; intervalo de confianza [IC] del 95 %: 0,5 - 1,9), curación secundaria (OR 1,1; IC del 95 % 0,2 - 3,2), curación general (OR 0,9; IC 95 % 0,5 - 1,7) o recurrencia en el seguimiento a largo plazo (OR 1,1; IC 95 % 0,4 - 18,8) en comparación con pacientes sin inyección de PRP.LIMITACIONES:Diseño retrospectivo, falta de imágenes postoperatorias y evaluación del seguimiento a largo plazo mediante un cuestionario.CONCLUSIÓN:La adición de la inyección de PRP no mejora el resultado a corto y largo plazo de la reparación con colgajo de avance endorrectal en pacientes con una fístula transesfintérica criptoglandular tratados en un centro de referencia terciario.

OBJECTIVE: To assess time trends in intestinal resection and re-resection in Crohn's disease (CD) patients. SUMMARY OF BACKGROUND DATA: CD treatment has changed considerably over the past decades. The effect of these advances on the necessity of intestinal resections and the risk of re-resection is unclear. METHODS: In this nationwide cohort study, adult CD patients with ileocolonic, small bowel, colon, or rectum resections between 1991 and 2015 were included. Data were retrieved from the Dutch nationwide network and registry of histopathology and cytopathology (PALGA). Time trends were analyzed with a broken stick model and Cox proportional hazard model with smoothing splines. RESULTS: The identified cohort comprised 8172 CD patients (3293/4879 male/female) in whom 10,315 intestinal resections were performed. The annual intestinal resection rate decreased nonlinearly from 1.9/100,000 (1991) to 0.2/100,000 (2015). A significantly steeper-decrease was observed before 1999 (slope 0.13) as compared to subsequent years (slope 0.03) (p<0.001). Analogous trends were observed for ileocolonic, small bowel, and colon resections. Overall cumulative risk of re-resection was 10.9% at 5 years, 18.6% at 10 years, and 28.3% at 20 years after intestinal resection. The hazard for intestinal re-resection showed a nonlinear decreasing trend, with hazard ratio 0.39 (95% confidence interval 0.36-0.44) in 2000 and hazard ratio 0.25 (95% confidence interval 0.18-0.34) in 2015 as compared to 1991. CONCLUSION: Over the past 25 years, intestinal resection rate has decreased significantly for ileocolonic, small bowel, and colonic CD. In addition, current postoperative CD patients are at 75% lower risk of intestinal re-resection.

OBJECTIVE: The purpose of this study was to assess the a priori chance that primary cystic lesions of the retrorectal space are malignant and to investigate MRI characteristics that indicate malignancy. MATERIALS AND METHODS: Patients referred to a center for colorectal surgery were recruited from 2000 to 2014. Lesions were proven by clinical assessment and histopathology. MRI was performed at 1.5 T with examinations evaluated by two radiologists. Interobserver agreement was assessed (Cohen kappa) and differences between malignant and benign lesions calculated (Fisher exact test). RESULTS: Twenty-eight patients (22 women, six men; age range, 18-70 years) with 31 lesions were included. Lesions were categorized as tailgut cysts (n = 16, 52%), teratomas (n = 9, 29%), lesions of colorectal origin (n = 4, 13%), or neurogenic lesions (n = 2, 6%). Five patients (18%) had malignant lesions. Colorectal lesions had the highest percentage of malignancy (3/4, 75%). A solid tissue component was found in all five (100%) malignant lesions and two (8%) of the benign lesions, which were both teratomas (p < 0.05). Sensitivity and specificity for malignancy according to the presence of a solid tissue component was 100% (5/5) and 92% (24/26). For unilocularity, multilocularity, debris, septa, and wall thickening, differences were not significant. Interobserver agreement was excellent (κ = 1) for all characteristics except debris (κ = 0.795). CONCLUSION: The majority of retrorectal cystic lesions are benign. The presence of a solid tissue component should raise suspicion for malignancy.

BACKGROUND: An unmet need remains for improved management in perianal fistulising Crohn's disease (pCD). Recently, local administration of adipose-derived cells has shown promising results. AIMS: To assess the safety and feasibility of injection of stromal vascular fraction (SVF) with platelet-rich plasma (PRP) in patients with pCD. METHODS: Patients ≥ 18 years with pCD were included and underwent fistula curettage, SVF with PRP injection, and closure of the internal opening. The primary endpoint was safety at 12 months. The secondary outcomes were complete radiological healing at 3 months (absence of fluid-containing tracts on MRI) and partial and complete clinical response at 3 and 12 months (closure of ≥1, respectively, all treated external opening(s)). RESULTS: Twenty-five patients were included (35 [IQR 25-40] years; 14 [56%] female); median CD duration 4 [IQR 2-8] years. Twenty-four (95%) patients had previously undergone fistula surgery. No adverse events were encountered at lipoharvesting sites. Two (8%) patients were readmitted to hospital and six (24%) underwent unplanned re-interventions. Post-operative MRI (n = 24) showed complete radiological healing in nine (37.5%) patients. Partial clinical response was present in 48% (12/25) at 3 months and in 68% (17/25) at 12 months, and complete clinical closure in five (20%) patients at 3 months and in 10 (40%) patients at 12 months. CONCLUSION: Injection with autologous SVF with PRP is feasible and safe in patients with treatment-refractory pCD. Early complete radiological healing was observed in more than one-third of patients, and clinical response in two-thirds of patients at 12 months.

BACKGROUND: Endoanal ultrasound is widely used for the detection of external and internal anal sphincter defects in patients with fecal incontinence. Recently, 3-dimensional transperineal ultrasound has been introduced as a noninvasive imaging method for the detection of these sphincter defects. OBJECTIVE: This study was designed to assess agreement between 3-dimensional transperineal ultrasound and 2-dimensional endoanal ultrasound regarding the detection of anal sphincter defects in women with fecal incontinence. DESIGN: This study was designed as a prospective observational study. SETTINGS: The study took place in a university hospital. PATIENTS: Between October 2008 and June 2009, all women with concerns of fecal incontinence underwent 2-dimensional endoanal ultrasound as well as 3-dimensional transperineal ultrasound. MAIN OUTCOME MEASURES: The main outcome measures are the presence of external and internal anal sphincter defects. RESULTS: Fifty-five patients were included. External and internal anal sphincter defects were observed with 2-dimensional endoanal ultrasound in 27 (49%) and 15 (27%) patients. Three-dimensional transperineal ultrasound detected an external and internal sphincter defect in 19 (35%) and 16 (29%) patients. The Cohen κ coefficient for the detection of external (κ = 0.63) and internal (κ = 0.78) anal sphincter defects was good. LIMITATIONS: This study's limitations include the absence of a surgical examination as the reference standard in the determination of sphincter defects. CONCLUSION: This study shows good agreement between 3-dimensional transperineal ultrasound and 2-dimensional endoanal ultrasound regarding the detection of anal sphincter defects. Based on these data, 3-dimensional transperineal ultrasound might be considered as a valuable alternative noninvasive investigation method.

BACKGROUND: Transanal advancement flap repair for the treatment of high transsphincteric fistulas fails in 1 of every 3 patients. Until now no definite risk factors for failure have been identified. The question is whether the more complex fistulas, such as those with horseshoe extensions and associated abscesses, have a less favorable outcome. OBJECTIVE: Aim of the present study was to indentify whether more complex fistulas have a less favorable outcome. DESIGN: This study is a retrospective case series review. PATIENTS: Between 1995 and 2007 a series of 162 patients underwent endoanal MR imaging before transanal advancement flap repair. Two investigators, without prior knowledge of the surgical findings, reviewed all MR images. RESULTS: Lateral fistulas were identified in 5 patients. Because of the small number, these patients were excluded from further analysis. Posterior fistulas were identified in 119 patients (76%). These fistulas had 3 types of extensions: a direct course (36%), a classic horseshoe extension (23%), or an intersphincteric horseshoe extension (41%). The corresponding healing rates were 37%, 81%, and 73%. Anterior fistulas were observed in 23% of the patients. These fistulas had 2 types of extensions: a direct course (61%) or a classic horseshoe extension (39%). The corresponding healing rates were 60% and 52%. The healing rate of fistulas with a direct course was significantly lower than the healing rate of fistulas with a classic or intersphincteric horseshoe extension. Associated abscesses were found in 47% of the posterior fistulas and 5% of the anterior fistulas. Once adequately drained, these abscesses did not affect the outcome of transanal advancement flap repair. CONCLUSION: The complexity of high transsphincteric fistulas does not affect the outcome of transanal advancement flap repair.

INTRODUCTION: It has been shown that vaginal delivery may result not only in sphincter defects, but also in pelvic floor injury. However, the influence of this type of injury on the etiology of fecal incontinence and its treatment is unknown. The present study was aimed to assess the prevalence of pelvic floor injury in patients who underwent anterior sphincteroplasty for the treatment of fecal incontinence and to determine the impact of this type of injury on the outcome of this procedure. METHODS: Women who underwent anterior sphincteroplasty in the past were invited to participate in the present study. With transperineal ultrasound, which has been developed recently, pelvic floor integrity was examined in 70 of 117 patients (60%). Follow-up was obtained from a standardized questionnaire. RESULTS: The median time period between anterior sphincteroplasty and the current assessment was 106 (range, 15-211) months. Pelvic floor injury was diagnosed in 43 patients (61%). Despite the prior sphincteroplasty, an external anal sphincter defect was found in 20 patients (29%). Outcome did not differ, neither between patients with and those without pelvic floor injury, nor between patients with and those without an adequate repair. However, patients with an adequate repair and an intact pelvic floor did have a better outcome than patients with one or both abnormalities. CONCLUSION: The majority of female patients with incontinence who were eligible for anterior sphincteroplasty have concomitant pelvic floor injury. Based on the present study, it seems unlikely that this type of injury itself has an impact on the outcome of anterior sphincteroplasty.

PURPOSE: It has been shown that vaginal delivery may result in pelvic floor injury. Until now it is unknown whether this type of injury plays a role in the etiology of fecal incontinence and whether it affects the outcome of treatment. The aim of the present study was to assess the prevalence of pelvic floor injury in patients with fecal incontinence who were eligible for sacral neuromodulation and to determine whether sacral neuromodulation is worthwhile in patients with pelvic floor injury. METHODS: All women with fecal incontinence who were eligible for sacral neuromodulation in the past were invited to participate in the present study. With transperineal ultrasound, which has been developed recently, pelvic floor integrity was examined in 46 of the 66 patients (70%). Follow-up was obtained from a standardized questionnaire. RESULTS: Pelvic floor injury was found in 29 of the 46 participants (63%). No differences regarding the efficacy of sacral neuromodulation were found between patients with and those without pelvic floor injury. Successful test stimulation was obtained in 86% of the patients with pelvic floor injury and in 71% of the patients without pelvic type injury. After implantation of a definitive pulse generator, a successful outcome was found in 84% of the patients with pelvic floor injury and in 75% of the patients with an intact pelvic floor. CONCLUSION: Pelvic floor injury is present in the majority of incontinent patients who were eligible for sacral neuromodulation. This type of injury seems to have no detrimental effect on the treatment outcome.

INTRODUCTION: Transanal advancement flap repair (TAFR) provides a useful tool in the treatment of high transsphincteric fistulas. Recent studies indicate that TAFR fails in one out of three patients. Until now, no definite predictive factor for failure has been identified. Although some authors have reported that preoperative seton drainage might improve the outcome of TAFR, this could not be confirmed by others. We conducted the present study to assess the influence of preoperative seton drainage on the outcome of TAFR in a relatively large series. METHODS: Between December 1992 and June 2008, a consecutive series of 278 patients [M/F = 179:99, median age 46 years (range, 19-73 years)] with cryptoglandular, transsphincteric fistula, passing through the upper or middle third of the external anal sphincter underwent TAFR. Patients were recruited from the colorectal units of two university hospitals (Erasmus Medical Center, Rotterdam, n = 211; and Leiden University Medical Center, Leiden, n = 67). Baseline characteristics did not differ between the two clinics. Sixty-eight of these patients underwent preoperative seton drainage for at least 2 months and until the day of the flap repair. RESULTS: Median healing time was 2.2 months. In patients without preoperative seton drainage, the healing rate was 63%, whereas the healing rate was 67% in patients who underwent preoperative seton drainage. This difference was not statistically significant. No differences in healing rates were found between the series from Leiden and Rotterdam. CONCLUSION: Preoperative seton drainage does not improve the outcome of TAFR.

PURPOSE: Anterior sphincteroplasty is the surgical treatment of choice for patients with fecal incontinence associated with an external anal sphincter defect. Recently it has been reported that patients with such a defect may also benefit from sacral neuromodulation. The success of this technique raises the question whether anterior sphincteroplasty still deserves a place in the surgical treatment of fecal incontinence. This study investigated the outcome of anterior sphincteroplasty in a large cohort of patients. METHODS: A consecutive series of 172 patients underwent anterior overlapping sphincteroplasty. A standardized questionnaire concerning current continence status, overall satisfaction, and quality of life was used to assess the outcome. RESULTS: Follow-up data were obtained from 75% of the 160 patients who were still alive at the time of the survey. After a median follow-up of 111 (range, 12-207) months, the outcome was still good to excellent in 44 patients (37%). In 28 patients (23%), the outcome was classified as moderate because these patients still experienced regular incontinence for stool. However, they were satisfied with their outcome because their incontinence episodes had been reduced by 50% or more. The outcome was poor in 40% of the patients. Predictors of worse outcome were older age (> or =50 years) at surgery, deep wound infection, and isolated external anal sphincter defects. Patients with follow-up of five or more years had the same outcome as patients with follow-up of fewer than five years. CONCLUSION: Anterior sphincteroplasty results in an acceptable to excellent long-term outcome in 60% of patients, especially in those under the age of 50 years at surgery.

INTRODUCTION: Transanal advancement flap repair provides a useful tool for the treatment of high transsphincteric fistulas. Recent studies indicate that transanal advancement flap repair fails in one of every three patients. Until now no definite risk factors for failure have been identified. A previous pilot study, conducted in our own institution, revealed a significant decrease in rectal mucosal blood flow after creation of the advancement flap. We postulated that impaired blood flow might result in breakdown of the distal part of the flap. This study was designed to evaluate the effect of rectal mucosal blood flow on the outcome of transanal advancement flap repair. METHODS: Between August 2004 and June 2007 a series of 54 patients with a high transsphincteric fistula underwent transanal advancement flap repair. The present series comprised 34 males and 20 females. Median age at the time of repair was 45 (range, 25-68) years. Rectal mucosal blood flow was determined by laser Doppler flowmetry before and after creation of the flap. The flow was expressed in arbitrary units. RESULTS: Transanal advancement flap repair was successful in 34 patients (63%). Median healing time was 2.2 months. Median mucosal blood flow before and after transanal advancement flap repair was 145 arbitrary units and 94 arbitrary units, respectively. This decrease was statistically significant. In a comparison of patients with and patients without a successful repair, no differences were found in mucosal blood flow before and after creation of the flap (146 vs. 138 arbitrary units and 83 vs. 104 arbitrary units). CONCLUSION: Rectal mucosal blood flow does not affect the outcome of transanal advancement flap repair.

BACKGROUND: The risk of gallstone disease necessitating cholecystectomy after ileal resection (IR) in Crohn's disease (CD) patients is not well established. We studied the incidence, cumulative and relative risk of cholecystectomy after IR in CD patients, and associated risk factors. METHODS: CD patients with a first IR between 1991 and 2015 were identified in PALGA, a nationwide pathology database in the Netherlands. Details on subsequent cholecystectomy and IR were recorded. Yearly cholecystectomy rates from the general Dutch population were used as a reference. RESULTS: A cohort of 8302 (3466 (41.7%) males) CD patients after IR was identified. During the 11.9 (IQR 6.3-18.0) years median follow-up, the post-IR incidence rate of cholecystectomy was 5.2 (95% CI 3.5-6.4)/1000 persons/year. The cumulative incidence was 0.5% at 1 year, 2.4% at 5 years, 4.6% at 10 years, and 10.3% after 20 years. In multivariable analyses, female sex (HR 1.9, CI 1.5-2.3), a later calendar year of first IR (HR/5-year increase, HR 1.27, CI 1.18-1.35), and ileal re-resection (time-dependent HR 1.37, CI 1.06-1.77) were associated with cholecystectomy. In the last decade, cholecystectomy rates increased and were higher in our postoperative CD population than in the general population (relative incidence ratio 3.13 (CI 2.29-4.28; p < 0.0001) in 2015). CONCLUSIONS: Although higher in females, increasing in recent years, and higher than in the general population, the overall risk of cholecystectomy in CD patients following IR is low and routine prophylactic measures seem unwarranted.

OBJECTIVE: Postoperative endoscopic recurrence in patients with Crohn's disease (CD) is commonly classified using the Rutgeerts score. Ulcerations in the ileal blind loop are not taken into account in the Rutgeerts score, and the clinical relevance of these lesions is unknown. This study aimed to assess the outcome of isolated ileal blind loop inflammation (IBLI) in postoperative CD patients. METHODS: Adult CD patients who underwent intestinal surgery with ileocolonic anastomosis between 1997 and 2017 were included and postoperative endoscopy reports were retrospectively reviewed. IBLI was defined as isolated inflammation of the ileal blind loop with or without ulcera confined to the anastomosis. Outcome was assessed using endoscopic recurrence (Rutgeerts >i2) and surgical recurrence (re-resection). RESULTS: A total of 341 CD patients were included. In 125 out of 341 (37%) patients, the ileal blind loop was described in the endoscopy reports. IBLI was reported in 43 of 341 (13%) patients. Start or step-up drug therapy was initiated in 10 of 32 (31%) IBLI patients with abdominal symptoms within a median of 0.9 months [interquartile range (IQR) 0.7-1.4] after ileocolonoscopy. Endoscopic recurrence occurred in 4 out of 38 (11%) IBLI patients without re-resection, within a median of 12.4 months (IQR 6.8-13.3). Intestinal re-resection was performed in 5 out of 43 (16%) IBLI patients within a median of 3.7 months (IQR 3.5-10.8). CONCLUSION: IBLI is associated with symptoms and an unfavorable outcome, with a high risk of endoscopic recurrence in the neoterminal ileum and intestinal re-resection during short-term follow-up. Therefore, the blind ileal loop needs to be assessed during endoscopy in postoperative CD patients.

BACKGROUND/AIMS: It has been suggested that normal function of both anal sphincters is essential for a good functional outcome after colonic J-pouch-anal anastomosis (CPAA). However, CPAA patients may have impaired continence despite adequate sphincter function. The present study was designed to identify those factors, which contribute to the functional outcome after a handsewn CPAA. MATERIALS AND METHODS: Forty patients were studied before and 1 year after pouch surgery. Faecal continence was evaluated using the Rockwood faecal incontinence severity index (RFISI). At both occasions, maximum anal resting pressure (MARP) and maximum anal squeeze pressure (MASP) were recorded. In addition, sensory perception threshold-volumes (SPT-V) and compliance were assessed using an 'infinitely' compliant polyethylene bag connected to an electronic barostat assembly. RESULTS: The median RFISI score 1 year after surgery was higher than the median RFISI score before surgery (13 vs 7 (p < 0.01). The median MARP dropped significantly (p < 0.01) whereas the median MASP remained unaffected. The mean compliance, calculated at three different sensation levels, and the pouch sensory perception threshold-volumes (PSPT-V) were lower than those of the original rectum (p < 0.05). The reduction of MARP showed no correlation with the post-operative change in RFISI scores. Low PC and low PSPT-V were associated with higher RFISI scores. CONCLUSION: Low pouch compliance and low SPT-V adversely affect functional outcome after a handsewn colonic J-pouch-anal anastomosis.

PURPOSE: The aim of the present study was to assess the integrity of the anal sphincters after handsewn pouch-anal anastomosis performed with the help of a Scott retractor. For this purpose the anal sphincters were visualized with three-dimensional endoanal ultrasonography. METHODS: Patients undergoing a colonic pouch-anal anastomosis or an ileal pouch-anal anastomosis were included. Before and six months after the procedure, the length and volume of both sphincters were assessed with three-dimensional endoanal ultrasonography, and anal manometry was performed. Continence scores were determined using the Fecal Incontinence Severity Index (FISI). RESULTS: Fifteen patients with a colonic pouch and 13 patients with an ileal pouch were examined. Six months after the procedure, three-dimensional endoanal ultrasonography showed significant alterations of the internal anal sphincter in eight patients with a colonic pouch-anal anastomosis (53 percent) and in eight patients with an ileal pouch-anal anastomosis (62 percent). These alterations were characterized by asymmetry or thinning. No defects were seen in the colonic pouch group, but, in two patients with an ileal pouch, a small defect in the internal anal sphincter was found. A decrease in internal anal sphincter volume was seen only in patients with a colonic pouch-anal anastomosis (P = 0.009). In both groups the length of the internal anal sphincter and the length, thickness, and volume of the external anal sphincter remained the same. After the procedure a reduction of maximum anal resting pressure was found in both groups (colonic pouch: P < 0.001, ileal pouch: P = 0.001). Maximum anal squeeze pressure was reduced in only patients with an ileal pouch-anal anastomosis (P = 0.006). The observed alterations of the internal anal sphincter and the manometric findings showed no correlation with the postoperative Fecal Incontinence Severity Index scores. CONCLUSION: Handsewn pouch-anal anastomosis, performed with the help of a Scott retractor, only rarely leads to internal anal sphincter defects, but three-dimensional endoanal ultrasonography shows alterations of the internal anal sphincter in 57 percent of the patients. No correlation was observed between these alterations and the functional outcome.

Transanal advancement flap repair has been advocated as the treatment of choice for trans-sphincteric perianal fistulas, because it enables the healing of almost all fistulas without sphincter damage and consequent continence disturbance. After initial promising reports, recently less favorable results have been reported. It remains unclear why there is such a large variety in the reported healing rates. Recently, it has been suggested that impaired wound healing caused by a diminished rectal mucosal perfusion in patients who smoke may lead to the breakdown of the advancement flap in patients undergoing flap repair for perianal fistulas. This study was designed to investigate the difference in blood flow in rectal mucosa between patients who smoke and those who do not smoke. Furthermore, we assessed the impact of the creation of a mucosa advancement flap and the difference in blood flow in the flap between smoking and nonsmoking patients. Between July 2001 and July 2002, 23 consecutive patients (19 males; median age, 46 (range, 26-69) years) with a perianal fistula of cryptoglandular origin underwent surgery for a perianal fistula. Among them were 13 patients who smoked cigarettes. All patients underwent intraoperative laser Doppler flowmetry. Median blood flow before transanal advancement flap repair was 35 (range, 8-70) volts in patients who did not smoke. In patients who smoked the median blood flow before transanal advancement flap repair was 18 (range, 7-35) volts. Blood flow was significantly lower in patients who smoked (P = 0.018; Mann-Whitney). In conclusion, it seems likely that impaired wound healing caused by a diminished rectal mucosal perfusion is a contributing factor in the breakdown of advancement flaps in patients who smoke cigarettes.

PURPOSE: Proctocolectomy with ileal pouch-anal anastomosis is the operation of choice for patients with refractory or fulminant ulcerative colitis. The most common long-term complication in these patients is pouchitis. This study was designed to investigate the efficacy of probiotic Lactobacillus rhamnosus GG in long-term delaying the first onset of pouchitis. METHODS: Between 1989 and 2001, a consecutive series of 127 patients presenting with ulcerative colitis underwent an ileal pouch-anal anastomosis at the Erasmus Medical Center in Rotterdam. Histopathologic investigation of the resected specimens revealed unsuspected Crohn's disease in five patients. Postoperative complications resulted in pouch excision in five patients. The remaining 117 patients were included in this study. All episodes of pouchitis occurring in this group were analyzed. Pouchitis was diagnosed on the basis of clinical symptoms and endoscopic and histologic features. The 39 patients, who underwent an ileal pouch-anal anastomosis between 1996 and 2001, started immediately after the operation with the daily intake of L. rhamnosus GG in a fermented product. The 78 patients, in whom an ileal pouch-anal anastomosis was performed between 1989 and 1996, received no L. rhamnosus GG. RESULTS: Except for the duration of follow-up, the patient characteristics, indications for proctocolectomy, number of postoperative complications, and functional outcome were similar in both groups. First episodes of pouchitis were observed less frequently in patients with a daily intake of L. rhamnosus GG (cumulative risk at 3 years: 7 vs. 29 percent; P = 0.011). CONCLUSIONS: Daily intake of fermented products containing L. rhamnosus GG provides significant clinical benefit, without side effects. Based on the results of this study, we recommend a daily intake of Lactobacillus rhamnosus GG (dose 1-2 x 10(10) bacteria) to delay the first onset of pouchitis.
