Background
The aim of this prospective study was to determine the efficiency of the Gore Bio-A synthetic plug in the treatment of anal fistulas.Methods
A synthetic bioabsorbable anal fistula plug was implanted in 60 patients. All fistulas were transsphincteric and cryptoglandular in origin.Results
The healing rate after 1 year of follow-up was 52 % (31 out of 60 patients). No patient was lost to follow-up. The treatment had no effect on the incontinence score. The plug dislodgement rate was 10 % (6 out of 60 patients). Thirty-four per cent of the patients (16 out of 47) required reoperation. The average operating time was 32 ± 10.2 min, and the average length of hospital stay was 3.3 ± 1.8 days.Conclusions
Synthetic plugs may be an alternative to bioprosthetic fistula plugs in the treatment of transsphincteric anal fistulas. This method might have better success rates than treatment with bioprosthetic fistula plugs.2.

Background
Optimal surgical treatment for anal fistula should result in healing of the fistula track and preserve anal continence. The aim of this study was to evaluate Permacol? collagen paste (Covidien plc, Gosport, Hampshire, UK) injection for the treatment of complex anal fistulas, reporting feasibility, safety, outcome and functional results.Methods
Between May 2013 and December 2014, 21 consecutive patients underwent Permacol paste injection for complex anal fistula at our institutions. All patients underwent fistulectomy and seton placement 6–8 weeks before Permacol? paste injection. Follow-up duration was 12 months.Results
Eighteen patients (85.7%) had a high transsphincteric anal fistula, and three female patients (14.3%) had an anterior transsphincteric fistula. Fistulas were recurrent in three patients (14.3%). Seven patients (33%) had a fistula with multiple tracts. After a follow-up of 12 months, ten patients were considered healed (overall success rate 47.6%). The mean preoperative FISI score was 0.33 ± 0.57 and 0.61 ± 1.02 after 12 months.Conclusions
Permacol? paste injection was safe and effective in some patients with complex anal fistula without compromising continence.3.
Background and aims
Closing the internal opening by a clip ovesco has been recently proposed for healing the fistula tract, but, to date, data on benefit are poorly analyzed. The aim was to report a preliminary multicenter experience.Materials and methods
Retrospective study was undertaken in six different French centers: surgical procedure, immediate complications, and follow-up have been collected.Results
Nineteen clips were inserted in 17 patients (M/F, 4/13; median age, 42 years [29–54]) who had an anal fistula: 12 (71 %) high fistulas (including 4 rectovaginal fistulas), 5 (29 %) lower fistulas (with 3 rectovaginal fistulas), and 6 (35 %) Crohn’s fistulas. Out of 17 patients, 15 had a seton drainage beforehand. The procedure was easy in 8 (47 %) patients and the median operative time was 27.5 min (20–36.5). Postoperative period was painful for 11 (65 %) patients. A clip migration was noted in 11 patients (65 %) after a median follow-up of 10 days (5.5–49.8). Eleven patients (65 %) who failed had reoperation including 10 new drainages within the first month (0.5–5). After a mean follow-up of 4 months (2–7),, closing the tract was observed in 2 patients (12 %) following the first insertion of the clip and in another one after a second insertion.Conclusion
Treatment of anal fistula by placing a clip on the internal opening is disappointing and deleterious for some patients. A better assessment before dissemination is recommended.4.

Background
The surgical treatment of complex anal fistulae, particularly those involving a significant portion of the anal sphincter in which fistulotomy would compromise continence, is challenging. Video-assisted anal fistula treatment (VAAFT), fistula tract laser closure (FiLaC?) and over-the-scope clip (OTSC®) proctology system are all novel sphincter-sparing techniques targeted at healing anal fistulae. In this study, all published articles on these techniques were reviewed to determine efficacy, feasibility and safety.Methods
A systematic search of major databases was performed using defined terms. All studies reporting on experience of these techniques were included and outcomes (fistula healing and safety) evaluated.Results
Eighteen studies (VAAFT—12, FiLaC?—3, OTSC®—3) including 1245 patients were analysed. All were case series, and outcomes were heterogeneous with follow-up ranging from 6 to 69 months and short-term (< 1 year) healing rates of 64–100%. Morbidity was low with only minor complications reported. There was one report of minor incontinence following the first reported study of FiLaC?, and this was treated successfully at 6 months with rubber band ligation of hypertrophied prolapsed mucosa. There are inconsistencies in the technique in studies of VAAFT and FiLaC?.Conclusions
All three techniques appear to be safe and feasible options in the management of anal fistulae, and short-term healing rates are acceptable with no sustained effect on continence. There is, however, a paucity of robust data with long-term outcomes. These techniques are thus welcome additions; however, their long-term place in the colorectal surgeon’s armamentarium, whether diagnostic or therapeutic, remains uncertain.5.
Background
The aim of this retrospective study was to assess our experience of 41 patients with anal fistulae treated with video-assisted anal fistula treatment (VAAFT).Methods
Forty-one consecutive patients with cryptoglandular anal fistulae were included. Patients with low intersphincteric anal fistulae or those with gross perineal abscess were excluded. Eleven (27 %) patients had undergone prior fistula surgery with 5 (12 %) having had three or more previous operations.Results
All patients underwent the diagnostic phase as well as diathermy and curettage of the fistula tracts during VAAFT. Primary healing rate was 70.7 % at a median follow-up of 34 months. Twelve patients recurred or did not heal and underwent a repeat VAAFT procedure utilising various methods of dealing with the internal opening. There was a secondary healing rate of 83 % with two recurrences. Overall, stapling of the internal opening had a 22 % recurrence rate, while anorectal advancement flap had a 75 % failure rate. There was no recurrence seen in six cases after using the over-the-scope-clip (OTSC®) system to secure the internal opening.Conclusions
VAAFT is useful in the identification of fistula tracts and enables closure of the internal opening. Adequate closure is essential with the method used to close large or fibrotic internal openings being the determining factor for success or failure. The OTSC system delivered the most consistent result without leaving a substantial perianal wound. Ensuring thorough curettage and drainage of the tract during VAAFT is also important to facilitate healing. We believe that this understanding will bring about a decrease in the high recurrence rates currently seen in many series of anal fistulae.6.

Background
Inflammatory bowel disease (IBD) is increasingly encountered in children. Early disease is associated with higher complication rate with increased incidence of surgical intervention.Patients and methods
From January 2010 to June 2015, 25 patients in the pediatric and adolescent age groups with IBD underwent surgical intervention in our center. They were classified into two groups. Group I included 15 patients with ulcerative colitis where 5 cases had left colon disease underwent left colectomy, while 10 cases had pancolonic disease underwent total colectomy and anal mucosectomy with ileo-anal or ileal pouch-anal anastomosis with covering ileostomy. Group II included 10 cases with Crohn’s disease where the indications for surgery were intestinal obstruction in seven cases, fulminant perianal infection with septic shock in one, perianal fistula and ulcers in one, and growth failure due to resistant intestinal fistula in one.Results
Group I included eight males and seven females; mean age at surgery was 10.6 years. There were postoperative complications in seven cases in the form of pelvic abscess and wound infection in one, wound infection in two, and recurrent pouchitis in four cases. Group II contained eight males and two females; mean age at surgery was 6.6 years. Two cases had recurrent symptoms after stricturoplasty. The mean length of time from diagnosis to surgery was 2.4 years (ranging from 6 to 36 months).Conclusion
A multidisciplinary team is mandatory for proper management of IBD cases. The risk of the disease and the expected surgical complications determine the timing of surgical interference.7.

Purpose
Treatment options for anal and perianal warts caused by human papillomavirus include topical application of cytotoxic substances or immunomodulators and ablative procedures. The objective of this prospective study was the evaluation of the ultrasound-driven Harmonic® Scalpel (Ethicon Endo-Surgery, Norderstedt, Germany) for resection of anal and perianal condylomata acuminata.Methods
Eight men and three women (age range, 26–72 years) with anal and perianal condylomata acuminata were treated by a Harmonic® Scalpel blade operating at a vibration frequency of 55.5 kHz and within a temperature range of 65°C to 120°C. Nine patients were treatment naïve, and two patients had recurrent disease. Follow-up ranged from 4 to 26 months.Results
Seven patients had perianal condylomata, two patients had exclusively intra-anal, and two patients had perianal and intra-anal warts. All condylomata were excised in a single-step procedure with complete clearing without injury of subepidermal layers. We observed no intraoperative or postoperative complications. No recurrences occurred during follow-up.Conclusions
The Harmonic® Scalpel has been an effective and safe method for the treatment of anal perianal human papillomavirus condylomata without recurrent warts. Subepidermal skin levels remained uninjured; thus, no complications or unsatisfactory cosmesis occurred.8.
Purpose
Sparing the extrinsic autonomic innervation of the internal anal sphincter during total mesorectal excision is important for the preservation of anal sphincter function. This study electrophysiologically confirmed the topography of the internal anal sphincter nerve supply during laparoscopic-assisted transanal minimally invasive surgery for total mesorectal excision.Methods
This prospective study was conducted at two large multispecialty referral centers. Six patients (five males and one female) aged between 45 and 65 years with low rectal cancer (≤5 cm from the anal verge) were enrolled. Surgery was performed under electric stimulation of the pelvic autonomic nerves with observation of the electromyographic signals of the internal anal sphincter.Results
The minimally invasive transanal surgical approach enabled advantageous visualization of the pelvic autonomic nerves in all patients. In particular, extrinsic innervation to the internal anal sphincter near the levator muscle was consciously spared under electrophysiological confirmation. The evoked absolute electromyographic amplitudes of the internal anal sphincter during transanal minimally invasive surgery were significantly lower than the initial results of the laparoscopic approach [3.7 μV (interquartile range 2.4; 5.7) vs. 4.3 μV (interquartile range 3.1; 8.6); p?=?0.002]. Five key zones of risk for pelvic autonomic nerve damage were identified. No complications occurred.Conclusions
The electromyographic results of this preliminary study indicate advantages for sparing the internal anal sphincter innervation during transanal minimally invasive mesorectal dissection considering the specific in situ neuroanatomical topography.9.

Background
Sphincter-preserving procedures for the treatment of transsphincteric fistulas fail in at least one out of every three patients. It has been suggested that failure is due to ongoing disease in the remaining fistula tract. Cytokines play an important role in inflammation. At present, biologicals targeting cytokines are available. Therefore, detection and identification of cytokines in anal fistulas might have implications for future treatment modalities. The objective of the present study was to assess local production of a selected panel of cytokines in anal fistulas, including pro-inflammatory interleukin (IL)-1β and tumor necrosis factor α (TNF-α).Methods
Fistula tract tissue was obtained from 27 patients with a transsphincteric fistula of cryptoglandular origin who underwent flap repair, ligation of the intersphincteric fistula tract or a combination of both procedures. Patients with a rectovaginal fistula or a fistula due to Crohn’s disease were excluded. Frozen tissue samples were sectioned and stained using advanced immuno-enzyme staining methods for detection of selected cytokines, IL-1β, IL-8, IL-10, IL-12p40, IL-17A, IL-18, IL-36 and TNF-α. The presence and frequencies of cytokine-producing cells in samples were quantitated.Results
The key finding was abundant expression of IL-1β in 93 % of the anal fistulas. Frequencies of IL-1β-producing cells were highest (>50 positive stained cells) in 7 % of the anal fistulas. Also, cytokines IL-8, IL-12p40 and TNF-α were present in respectively 70, 33 and 30 % of the anal fistulas.Conclusions
IL-1β is expressed in the large majority of cryptoglandular anal fistulas, as well as several other pro-inflammatory cytokines.10.

Background
The aim of the present study was to evaluate the safety and efficacy of autologous, micro-fragmented and minimally manipulated adipose tissue injection associated closure of the internal opening in promoting healing of complex anal fistula.Methods
A pilot study was conducted on patients referred to our center with anal fistula, from April 2015–December 2016. Inclusion criteria were age over 16 years old and a diagnosis of complex anal fistula according to the American Gastroenterological Association classification The patients were divided into 2 groups; the “first time group” (Group I) in which micro-fragmented adipose tissue injection with closure of the internal opening was the first sphincter-saving procedure, and the “recurrent group” (Group II) consisting of patients who had failed prior sphincter-saving procedures. The procedure was carried out 4–6 weeks after seton placement. Follow-up visits were scheduled at 7 days, and 1, 3, 6 and 12 months after surgery. Fistula healing was defined as the closure of the internal and external openings without any discharge.Results
Out of 47 patients with complex transsphincteric anal fistula, 19 met the inclusion criteria and were selected to undergo the procedure. Twelve of these patients (Group I) had micro-fragmented adipose tissue injection as first-line treatment, and 7 (Group II) had failed previous sphincter-saving procedures. The mean operative time was 55 ± 6 min (range 50–70 min). The mean postoperative pain score measured with the visual analog pain scale was 2 ± 1.4 (range 0–4). No intraoperative difficulties related to the use of the kit were recorded. There were no cases of postoperative fever or abdominal sepsis related to the procedure and no post-treatment perianal bleeding or impaired anal continence. Only 3 cases of minor abdominal wall hematoma that did not require any treatment and 1 case of perianal abscess were observed. Patients were evaluated for a mean follow-up time of 9 ± 3.1 months (range 3–12 months). The overall healing rate was 73.7, 83.3% for Group I and 57.1% for Group II.Conclusions
The injection of autologous, micro-fragmented and minimally manipulated adipose tissue associated with closure of the internal opening is a safe, feasible and reproducible procedure and may enhance complex anal fistula healing.11.
Background
For patients with rectal prolapse undergoing Ventral Rectopexy (VR), the impact of prior prolapse surgery on prolapse recurrence is not well described.Purpose
The purpose of this study was to compare recurrence rates after VR in patients undergoing primary and repeat rectal prolapse repairs.Design
This study is a prospective cohort study.Methods
IRB-approved prospective data registry of consecutive patients undergoing VR for full-thickness external rectal prolapse between 2009 and 2015.Main outcome measures
Rectal prolapse recurrence was defined as either external prolapse through the anal sphincters or symptomatic rectal mucosa prolapse warranting additional surgery. Preoperative and postoperative morbidity and functional outcomes were analyzed. Actuarial recurrence rates were calculated using the Kaplan-Meier method.Results
A total of 108 VRs were performed during the study period. Seventy-two were primary and 36 repeat repairs. Seven cases were open, 23 laparoscopic, and 78 robotic. Six cases were converted from laparoscopic/robotic to open. In 63 patients, VR was combined with gynecological procedures. There were no statistical differences between primary or recurrent prolapse for the following: demographics, operative time, concomitant gynecologic procedures, complications, blood loss, and graft material type. Length of stay was longer in patients with a history of prior prolapse surgery (p = 0.01). Prolapse recurrence rates for primary repairs were reported at 1.4, 6.9, and 9.7% and for recurrent prolapse procedures 13.9, 25, and 25% at 1, 3, and 5 years (p = 0.13). Mean length of follow-up was similar between groups. Time to recurrence was significantly shorter in patients undergoing repeat prolapse surgery 8.8 vs 30.7 months (p = 0.03).Conclusions
VR is a better option for patients undergoing primary rectal prolapse repair.12.

Background
Anorectal malformations (ARMs) are rarely seen in adults, since majority of cases are corrected in infancy or childhood. The aim of this study was to describe the profile of patients who underwent definitive surgery to correct their ARM in adulthood, and to discuss the outcomes of surgery (morbidity, mortality, and function).Methods
This retrospective study included patients 18 years old and above, managed surgically by the Division of Colorectal Surgery at the Philippine General Hospital, University of the Philippines, Manila, from January 1, 2004, to December 31, 2012. Data from the Integrated Surgical Information System and the patients’ hospital records were used to fill out a Data Collection Form. Frequencies and percentages were then computed.Results
Eight patients were included in the study. The most common reason for consult was recurrent urinary tract infection (UTI, 25%). One patient had an imperforate anus (IA) without a fistula, and 1 patient had IA with rectal atresia, and the 6 had an IA with a fistula. All but one (87.5%) of the patients had undergone a prior diversion in infancy or childhood. Definitive surgical procedures included posterior sagittal anorectoplasty (PSARP) in 3 patients, anal transposition in 2 patients, laparotomy with colocutaneous anastomosis in two patients, and laparotomy and PSARP in 1 patient. There were 3 cases (37.5%) of postoperative complications. These complications included ureteral injury, enterocutaneous fistula, anal stricture, rectal stricture, rectovesical fistula, and recurrent rectourethral fistula. There was no reported mortality. Five patients already had their stomas reversed at the time of this writing.Conclusion
Our results showed that the rarity of the disease, limited surgical experience, and a technically challenging anatomy make the management of ARMs that persist into adulthood a formidable undertaking.13.
Background
Lateral internal anal sphincterotomy (LIS) is considered the treatment of choice for chronic anal fissure. This study aimed to compare the outcome of standard LIS and posterolateral internal sphincterotomy (PLIS) at 5 o’clock position as regards healing of anal fissure, improvement in symptoms, and complications.Methods
Patients with chronic anal fissure were randomly allocated to one of two groups; group I underwent PLIS and group II underwent LIS. Patients were compared regarding the duration of healing of anal fissure, improvement in anal pain as recorded by visual analogue scale (VAS), complications, particularly fecal incontinence (FI) and changes in the anal pressures.Results
Eighty (49 females) patients were included to this trial. The mean age of patients was 35.5 years. The duration of healing was significantly shorter in group I than in group II (4.1?±?1.7 vs 5.8?±?1.4 weeks; p?<?0.0001). Group I achieved significantly lower pain score at 1 month postoperatively than group II (1.1?±?0.9 vs 1.7?±?0.98; p?=?0.005). Two (2.5%) of group I patients and six (10%) of group II patients experienced minor FI postoperatively. The postoperative reduction in the mean resting anal pressure in group I was significantly higher than that in group II.Conclusion
Time to complete healing was significantly shorter and pain score was significantly lower after PLIS than after LIS which can be due to more reduction in the resting anal pressure after PLIS. Continence disturbances occurred after PLIS less frequently than after LIS; however, no significant differences between the two techniques were noted.Trial registration

Background
Fistula-in-ano has a reported incidence of 31–34%. Besides fistulotomy, options for fistula repair are seton placement, endorectal advancement flap (ERAF), fibrin sealant, anal fistula plug and ligation of the intersphincteric fistula tract. Despite having a reported success rate as high as 75–98%, ERAF is not without complications, including flap breakdown, recurrence and fecal incontinence. Traditionally, maintaining a broad base to preserve blood supply has been advocated to reduce flap failure. And the aim of the present study was to evaluate outcomes of adult patients who underwent ERAF for complex fistula-in-ano with the use of intraoperative fluorescence angiography (FA) at our institution between July 2014 and July 2016.Methods
We retrospectively reviewed consecutive cases of complex fistula-in-ano repair with ERAF and FA from a prospectively maintained dataset of adult patients with complex fistula-in-ano. Demographics, intraoperative data and 60-day outcomes were recorded and reviewed.Results
Six patients [five males and one female with a mean age of 40 years (range 25–46 years)], with a total of seven fistulas, were identified. Six (85.7%) of these patients had undergone prior surgery for fistula-in-ano. No recurrences or complications of any type were noted at 2-week and 8-week follow-up. The majority of patients (71.4%) required flap revision based on intraoperative FA prior to flap fixation.Conclusions
FA is safe and offers real-time assessment of flap perfusion prior to and after fixation in anal fistula repair. The rate of flap ischemia may be underestimated, and therefore, to improve outcomes in ERAF, intraoperative FA should be included in the surgical armamentarium.15.

Purpose
The treatment of high transsphincteric fistula is a complex procedure, which may be associated with the risk of recurrence and fecal incontinence. In this study, we used an animal model to compare different types of sphincter-preserving treatments for transsphincteric fistula.Methods
Sixteen female New Zealand rabbits, weighing 2.8–4.8 kg underwent a surgical creation of high transsphincteric fistula. After 6 weeks, magnetic resonance imaging (MRI) was performed in order to confirm fistula formation and measure the fistula diameter. The rabbits were divided into three groups. Group 1 received no plug treatment (control). Autologous dermal graft and acellular dermal matrix were used as a plug in groups 2 and 3, respectively. Five weeks after treatment, fistula tract healing was determined by measuring the largest fistula diameter with MRI. All rabbits were euthanized and the anorectum excised en bloc for histopathological examination.Results
According to the MRI findings, all groups showed significant healing after the treatment (p?<?0.05). The healing rate of fistula diameters after treatment was 40, 66, and 29 % in the control, dermal graft, and acellular dermal matrix groups, respectively. In terms of negative healing parameters such as neutrophil, eosinophil, lymphocyte, and plasmocyte accumulation, dermal graft and acellular dermal matrix groups showed significantly lower results than those in the control group (p?<?0.05).Conclusion
According to MRI and histopathological results, fistula tract curettage and fistula orifice closure improved transsphincteric anal fistula healing. Additionally, in this study, plug treatment favoring autologous dermal graft resulted in better healing.16.

Background
Abdominal abscess that result from bowel injury may require treatment with percutaneous drainage. In some cases, an abscess-associated fistula develops between the injured bowel and the drainage catheter. Fistulas that fail to resolve may require surgery; however, fibrin glue therapy (FGT) may be a suitable alternative.Methods
We retrospectively identified patients undergoing FGT for an abscess-associated enteric fistula between 2004 and 2015. Success was defined as closure of the fistula tract without need for additional intervention. A multivariable logistic regression analysis was utilized to identify factors associated with success.Results
We identified 34 patients with a median age of 54 (23–87) years and 24 (71 %) males. FGT was successful in 23 (67 %) patients. On multivariate analysis, a tract width less than 5 mm (OR 19.2, 95 % CI 1.7–214.5) and removal of the drain (OR 13.8, 95 % CI 1.2–157.6) predicted FGT success. The time from initial FGT to resolution was significantly decreased for the patients who were successfully treated compared to those who failed 24 (14–38) days vs. 99 (71–175) days, respectively (p < 0.001).Conclusions
Fibrin glue therapy for abscess-associated enteric fistula results in successful and accelerated healing in the majority of cases. Factors associated with successful fibrin glue therapy were identified.17.

Background
Anal fistula is a common acquired anorectal disorder in children. Treatment methods that have been used are associated with inconsistent results and possible serious complications. In 2011 a minimally invasive approach, video-assisted anal fistula treatment (VAAFT) was described for adult patients. The aim of the present study was to assess the first series of pediatric patients treated with VAAFT.Methods
All patients who underwent VAAFT between August 2013 and May 2015 were included. Demographics, clinical features, preoperative imaging, surgical details, outcome, and medium-term data were prospectively collected for each patient.Results
Thirteen procedures were performed in nine patients. The male to female ratio was 8:1, and the median age was 9.6 years. Five fistulas were idiopathic, three iatrogenic, and one associated with Crohn’s disease. Eight complete VAAFT procedures were performed. The remaining five procedures were either fistuloscopy and cutting seton placement or fistuloscopy and electrocoagulation, both without mucosal sleeve. The median length of surgery was 41 min. The median hospital stay was 24 h, and the median length of follow-up was 10 months. Resolution of the fistula was observed in all patients who underwent a complete VAAFT. In four out of five patients who underwent an incomplete procedure (without mucosal sleeve), the fistula recurred. No incontinence or soiling was reported in the medium term.Conclusions
VAAFT proved to be feasible and safe in children. It also proved to be versatile as it could be applied to fistulas of different etiologies. The key to success seems to be an adequate mucosal sleeve. Older children and adolescents benefit most from VAAFT which is a valid alternative to available surgical procedures.18.
Purpose
Rectovaginal fistulas are difficult to treat completely, especially when patients present with a history of multiple surgeries and radiation therapy. We aimed to evaluate the efficacy of gracilis muscle flap transposition to treat rectovaginal fistula.Methods
We performed a retrospective chart review of all gracilis muscle transposition cases and other procedures between January 2009 and July 2016.Results
Total 53 cases were reviewed. A total of 11 patients underwent gracilis muscle flap transposition for rectovaginal fistula repair, with 8 patients showing good results without recurrence (total success rate, 72.7%). Comparison of this patient group with patients who had undergone other surgical procedures for rectovaginal fistula repair showed that those who received a gracilis transposition flap had significantly higher average number of previous surgeries (2.18 ± 1.17 vs. 1.1 ± 1.25) and had previously undergone radiotherapy at a significantly higher rate (63.6 vs. 26.2%). Furthermore, none of our patients complained of donor site discomfort.Conclusions
Based on these results, we recommend using the gracilis muscle flap for rectovaginal fistula repair in cases where there is a history of radiotherapy and had surgical failure more than twice.19.

Background
Low anterior resection syndrome (LARS) is frequent following sphincter-sparing procedures for rectal cancer.Objective
This study aims to assess surgeons’ awareness of LARS.Design
This was a survey study.Settings
Members of the American Society of Colon and Rectal Surgeons (ASCRS), the Spanish Association of Surgeons (AEC), and the Spanish Society of Coloproctology (AECP).Participants
Three hundred thirty-four surgeons from the ASCRS and 150 from the Spanish Societies completed a 23-item electronic questionnaire.Main outcome measures
Surgeons’ opinions regarding different aspects of LARS.Results
The proportion of rectal cancer patients undergoing sphincter-sparing operations ranged between 71 and 90 %. Low anterior resection with end-to-end anastomosis was the most frequently cited procedure after mesorectal excision. More than 80 % of participants were recognized to be moderately or extremely aware of the condition, but regarding the method used to assess LARS, the majority relied on clinical manifestations. Around 35 % of surgeons considered that severe LARS developed in less than 40 % of patients. The most important factor related to defecatory function impairment in the surgeons’ opinion was the distance from the anal margin to anastomosis. Other factors thought to be involved were anastomotic leakage, preoperative radiation therapy, age, and postoperative radiotherapy, with similar percentages in the two groups of surgeons. Lifestyle changes and dietary measures associated with or without drug treatment was the modality of choice. The experience with transanal irrigation or sacral nerve stimulation was limited. It was considered that <30 % of patients chronically suffer from severe LARS with significant quality of life impairment.Limitations
The limitations of this study are the international mix and expert status of the specialists.Conclusions
The probability of patients suffering from LARS was underestimated despite reporting good knowledge of the syndrome. Validated methods for the assessment of LARS were rarely used. Deficient awareness regarding risk factors for LARS was documented. Knowledge of therapeutic options was also limited.20.
