RESUMO
BACKGROUND: Sphincter-preserving techniques like autologous compound platelet-rich fibrin foam have gained popularity, offering potential for better functional outcomes in anal fistula treatment. The present study aimed to evaluate the efficacy and safety of Obsidian RFT®. METHODS: The study conducted a retrospective analysis from January 2018 to December 2022 on patients who received anal fistula closure with Obsidian RTF® at the Department of General Surgery, Medical University of Vienna. Clinical diagnosis, complemented by radiographic imaging, was employed to confirm inconclusive cases. Demographic and fistula characteristics and postoperative data were collected from electronic records following STROCSS criteria. RESULTS: Fifteen patients received Obsidian RFT® treatment for anal fistulas. We found no intra- and postoperative complications. The median hospital stay was 3 days. After a median follow-up of 32 months, a closure rate of 53.3% was detected. Non-significant differences were observed in various variables, yet trends emerged, indicating associations between abscess presence and non-healing fistulas. A distinct age threshold (≥ 42.7 years) served as an indicator for an inability to achieve anal fistula cure. CONCLUSION: Obsidian RFT® represents a safe, minimally invasive operative procedure. Approximately half the patients experienced healing, with better outcome in a younger population. TRIAL REGISTRATION: Ethical Approval number Medical University of Vienna (#1258/2018). This study was registered retrospectively in ClinicalTrials.gov (NCT06136325).

BACKGROUND: Sacral neuromodulation (SNM) is a common treatment for patients with urinary and faecal incontinence. A close contact of the tined lead electrode with the targeted nerve is likely to improve functional outcome. The aim of this study was to compare the position of the SNM lead in relation to the sacral nerve by comparing different implantation techniques. METHODS: This cadaver study was conducted at the Division of Anatomy of Vienna's Medical University in October 2020. We dissected 10 cadavers after bilateral SNM lead implantation (n = 20), using two different standardized implantation techniques. The cadavers were categorized as group A (n = 10), representing the conventional guided implantation group and group B (n = 10), where SNM implantation was conducted with the novel fluoroscopy-guided "H"-technique. The primary goal was to assess the distance between the sacral nerve and the lead placement. RESULTS: The electrodes were inserted at a median angle of 58.5° (46-65°) in group A and 60° (50-65°) in group B, without reaching statistical significance. In 8 cadavers, the lead entered the S3 foramen successfully. The median distance of the lead to the nerve did not show a significant difference between both groups (E0: Group A: 0.0 mm vs. Group B: 0.0 mm, p = 0.969; E1: Group A: 0.0 mm vs. Group B: 0.5 mm p = 0.754; E2: Group A: 2.5 mm vs. Group B: 2.5 mm p = 1.000; E3: Group A: 3.5 mm vs. Group B: 4.0 mm p = 0.675). In 2 cases (20%) of the conventional group A, the lead was misplaced and located at the gluteal muscle. Perforation of the presacral fascia was observed in one lead placement in group A and in two placements in group B. CONCLUSIONS: Both standardized implantation techniques may ensure close electrode proximity to the targeted nerve. Misplacement of the electrode was more often observed with the conventional implantation technique.

AIM: Crohn's disease (CD)-related rectovaginal fistulas (RVFs) are rare, challenging to treat and associated with a high morbidity. Due to a significant lack of data, we aimed to analyse the safety and feasibility of allogeneic adipose-derived stem cells (ASCs) in the treatment of CD-related RVF. METHOD: Four consecutive patients with CD-related RVF underwent treatment with expanded allogeneic ASCs extracted from a healthy donor in a tertiary referral centre in 2019. None of the patients had an intestinal diversion at the time of the treatment. Follow-up was performed 6 months postoperatively. RESULTS: The median operation time was 45 min with a median hospital stay of 3 days. No intra-operative complications occurred. Three patients (75%) developed recurrent RVF after a median follow-up of 19 days. Two patients required surgical treatment including loose seton drainage due to discharge and pain. One patient developed recurrence of symptoms after 10 days, but refused further surgical therapy. Only one patient (25%) showed healing of the RVF, with re-epithelialization of both the vaginal and rectal opening and absence of clinical symptoms. CONCLUSION: Expanded allogeneic ASC therapy represents a novel safe treatment option for CD-associated RVF. Although efficacy appears limited, further controlled studies are required to draw robust conclusions.

BACKGROUND: Sacral neuromodulation (SNM) is an established treatment option for patients with faecal incontinence. The location of the stimulating electrode is considered to be essential for treatment success. The purpose of this study was to evaluate the position of SNM electrodes after using a standardized fluoroscopy-guided implantation technique. METHODS: For this cadaver study, SNM electrodes were implanted bilaterally in 5 lower body specimens. The lower edge of the sacroiliac joint and the medial edge of the sacral foramina were marked using fluoroscopy to draw an 'H' with the crossing points identifying S3. After electrode placement the pelvis was dissected to describe the exact position of the SNM electrodes. RESULTS: The electrodes were inserted at an angle with a median degree measure of 60° (range 50-65°) to the skin, with a median distance of 9 mm (range 0-13 mm) from the S3 marking. All electrodes entered the third sacral foramen. The median distance of the electrodes to the sacral nerve was 0 mm (range 0-3 mm) for the most proximal, 0.5 mm (range 0-5 mm) for the second, 2.25 mm (range 0-11 mm) for the third and 1.75 mm (range 0-16 mm) for the most distant electrode. There was neither a significant difference in the proximity of the electrodes to the nerve between the right and left side (proximal to distal electrode: p = 0.18, p = 0.16, p = 0.07, p = 0.07) nor between male and female cadavers (p = 0.25, p = 0.21, p = 0.66, p = 0.66). CONCLUSIONS: A standardized fluoroscopy-guided implantation technique enables a close contact between electrode and nerve. This can potentially result in an improved clinical outcome.

AIM: The risk factors that predict surgical recurrence in Crohn's disease (CD) remain controversial. Postoperative anti-tumour necrosis factor (anti-TNF) therapy might lower recurrence rates whilst the presence of mesenteric granulomas has been postulated to increase the risk. We hypothesized that mesenteric granulomas indicate disease severity and might predict the risk of surgical recurrence, irrespective of immunosuppressive therapy. METHOD: We performed a retrospective review of all consecutive patients undergoing operations for CD between January 2000 and December 2014 at a single tertiary referral centre and assessed the perioperative factors and histological findings at the time of surgery. Surgical recurrence rates and the immunosuppressive regimen were assessed through retrospective chart review and telephone interviews. RESULTS: A total of 274 patients were eligible for analysis. Median follow-up was 8.54 (5.48-14.42) years. A total of 63 patients (23.0%) underwent surgery for recurrent CD after a median of 4.75 (2.10-7.96) years. In final histology, 35 (12.8%) patients had mesenteric granulomas. TNF inhibitors were administered postoperatively in 104 (38.0%) and thiopurines in 137 (50.0%) patients. In univariate analysis, only the presence of mesenteric granulomas [hazard ratio (HR) 1.95; 95% CI 1.05-3.62; P = 0.035] significantly increased the risk for recurrent surgery while postoperative anti-TNF (HR 0.85; 95% CI 0.49-1.50; P = 0.581) or thiopurine therapy (HR 1.03; 95% CI 0.61-1.73; P = 0.916) did not. In multivariate analysis, only the presence of mesenteric granulomas significantly influenced the risk of surgical recurrence (HR 1.94, 95% CI 1.04-3.60; P = 0.037). CONCLUSION: Intestinal and mesenteric granulomas should be differentiated in pathology reports, because mesenteric, but not intestinal, granulomas may be associated with an increased risk of surgical recurrence.

BACKGROUND: The causes and consequences of genome size variation across Eukaryotes, which spans five orders of magnitude, have been hotly debated since before the advent of genome sequencing. Previous studies have mostly examined variation among larger taxonomic units (e.g., orders, or genera), while comparisons among closely related species are rare. Rotifers of the Brachionus plicatilis species complex exhibit a seven-fold variation in genome size and thus represent a unique opportunity to study such changes on a relatively short evolutionary timescale. Here, we sequenced and analysed the genomes of four species of this complex with nuclear DNA contents spanning 110-422 Mbp. To establish the likely mechanisms of genome size change, we analysed both sequencing read libraries and assemblies for signatures of polyploidy and repetitive element content. We also compared these genomes to that of B. calyciflorus, the closest relative with a sequenced genome (293 Mbp nuclear DNA content). RESULTS: Despite the very large differences in genome size, we saw no evidence of ploidy level changes across the B. plicatilis complex. However, repetitive element content explained a large portion of genome size variation (at least 54%). The species with the largest genome, B. asplanchnoidis, has a strikingly high 44% repetitive element content, while the smaller B. plicatilis genomes contain between 14 and 25% repetitive elements. According to our analyses, the B. calyciflorus genome contains 39% repetitive elements, which is substantially higher than previously reported (21%), and suggests that high repetitive element load could be widespread in monogonont rotifers. CONCLUSIONS: Even though the genome sizes of these species are at the low end of the metazoan spectrum, their genomes contain substantial amounts of repetitive elements. Polyploidy does not appear to play a role in genome size variations in these species, and these variations can be mostly explained by changes in repetitive element content. This contradicts the naïve expectation that small genomes are streamlined, or less complex, and that large variations in nuclear DNA content between closely related species are due to polyploidy.

AIM: As adjuvant chemotherapy in colorectal cancer relies on the identification of lymph node metastases, the pathologist's dedication may have a considerable influence on postoperative survival. METHOD: The aim of this retrospective study was to assess the impact of the pathologist's dedication on lymph node detection rate and postoperative survival in patients operated on by a single experienced colorectal surgeon within a 5-year period. We assessed 229 patients undergoing total mesorectal excision or complete mesocolic excision by the senior author between 1 January 2009 and 31 December 2013. Pathologists were grouped as 'general pathologist' or 'dedicated pathologist' depending on their dedication/specialization. RESULTS: Dedicated pathologists found statistically significantly more lymph nodes in colorectal specimens than general pathologists [23 (interquartile range 24) vs 14 (interquartile range 11), respectively; P < 0.001]. The detection rate of ≥ 12 lymph nodes per specimen was significantly higher in the dedicated pathologist group [65/74 (87.8%) vs 105/155 (67.7%); P = 0.016]. However, postoperative survival did not differ in the respective subgroups. In the multivariable analysis by Cox proportional hazard model, International Union against Cancer Stage IV was the only factor associated with decreased disease-specific survival (hazard ratio 28.257; 95% CI 3.850-207.386; P = 0.001). CONCLUSION: In our centre, the pathologist's dedication has an impact on lymph node detection rate but does not influence postoperative disease-specific survival.

AIM: Ventral rectopexy (VR) has gained popularity in the management of obstructive defaecation syndrome (ODS) due to a symptomatic rectocele ± intussusception. Data on the efficacy and safety of VR are variable and there are few predictors of successful outcome. This study aimed to examine whether or not an adverse obstetric history influenced the functional outcome following VR for ODS. METHOD: This was a retrospective study of a cohort of 76 consecutive patients who had undergone VR for ODS at a tertiary referral centre between 2012 and 2015. Patients were followed up by telephone questionnaire. The obstetric history and pre- and postoperative symptoms of ODS and faecal incontinence (FI) were obtained from telephone interviews. RESULTS: In this cohort, symptoms of ODS were significantly improved by surgery, with 56% of patients showing a reduction of symptoms of 50% or more (P < 0.001). Subgroup analysis demonstrated that a lower body mass index (BMI; 24.4 vs 27.3 kg/m2 ; P < 0.05) and shorter duration of symptoms (7 vs 10 years; P < 0.05) led to a better outcome. VR had no effect on FI. Obstetric factors such as foetal weight, instrumental delivery, episiotomy, perineal tear and total number of deliveries did not influence outcomes. CONCLUSION: Patients with a less straightforward obstetric history can be reassured that this should not adversely influence the functional outcome after VR for ODS. Colorectal surgeons who offer this surgery should warn patients with an elevated BMI or with longstanding symptoms that the operation may be less successful than for those with a lower BMI or shorter duration of symptoms.

AIM: The use of a loose seton for complex anal fistulae can cause perianal discomfort and reduced quality of life. The aim of this study was to assess the impact of the novel knot-free Comfort Drain on quality of life, perianal comfort and faecal continence compared to conventional loose setons. METHOD: Forty-four patients treated for complex anal fistula at a single institution between July 2013 and September 2014 were included in the study. A matched-pair analysis was performed to compare patients with a knot-free Comfort Drain and controls who were managed by conventional knotted setons. The 12-item Short Form survey (SF-12) questionnaire was used to assess quality of life. Additionally, patients reported perianal comfort and faecal incontinence using a Visual Analog Scale (VAS) and the St Mark's Incontinence Score. RESULTS: The Comfort Drain was associated with improved quality of life with significant higher median physical (P = 0.001) and mental (P = 0.04) health scores compared with a conventional loose seton. According to the VAS, patients with a Comfort Drain in situ reported greater perianal comfort with significantly less burning sensation (P < 0.001) and pruritus (P < 0.001). Faecal continence was similar in each group. CONCLUSION: The Comfort Drain offers improved perianal comfort and better quality of life compared with a conventional loose seton and therefore facilitates long-term therapy in patients with complex fistula-in-ano.

BACKGROUND: The current study was conducted to assess long-term outcomes after primary ileocolic resection for Crohn's disease (CD) and to identify factors associated with surgical relapse in the era of immunosuppressive medications. METHODS: Data were collected retrospectively on 116 consecutive patients, who underwent primary ileocolic resection for CD at a tertiary referral center between 1997 and 2006. Medical records were reviewed, and the use of immunomodulators was noted. The cumulative probability for a second operation due to recurrent CD was described by Kaplan-Meier curves. RESULTS: Ten patients (8.6 %) developed surgical recurrence after a mean follow-up period of 8.1 (±2.6) years. The percentage of patients not requiring further surgery was 96.5% and 88.0 % at 5 and 10 years, respectively. An urgent indication for surgery was significantly associated with the necessity of repeated intestinal resection (hazard ratio 5.6, 95 % confidence interval 1.2-27.0, p = 0.0145). In addition, postoperative exposure to azathioprine/6-mercaptopurine for more than 3 months decreased the probability of surgical recurrence significantly (hazard ratio 2.5, 95 % confidence interval 0.6-9.9, p = 0.0349). CONCLUSIONS: In contrast to previous studies, we observed a significant low surgical recurrence rate after primary ileocolic resection. Additionally, maintenance treatment with azathioprine/6-mercaptopurine after surgery may reduce the necessity for repeat surgical intervention.

BACKGROUND: The aim of this study was to assess sexual function and quality of life (QoL) in patients after surgery for perianal Crohn's disease. METHODS: Eighty-eight consecutive patients with perianal Crohn's disease, operated on at the Medical University of Vienna, completed a self-administered questionnaire including the International Index of Erectile Function (IIEF), Female Sexual Function Index (FSFI), Short Form-12 Health Survey (SF-12), and the Inflammatory Bowel Disease Questionnaire (IBDQ). Patients with a current stoma were excluded from further analysis. The median follow-up time was 104 months (range 3-186 months). Healthy subjects served as controls for each case and were matched by age (±6 years) and gender. Forty-seven (68 %) female and 22 male patients with a median age of 46.5 years (range 18-64 years) were analyzed. Eleven (16 %) patients had simple and 58 (84 %) complex anal fistulas. RESULTS: The median SF-12 physical health score of the patients was significantly lower (47.9 (range 25.5-57.2)) than that of the controls (54.3 (range 34.6-61.8); p = 0.03). Not surprisingly, the median total sore of the IBDQ of the controls was significantly better than that of the patients (controls: 188.5 (range 125-206.5), patients: 157 (range 60-199.5); p < 0.0001). Analysis with the multiple logistic regression test showed that type of operation, >1 perianal fistula opening, and active Crohn's disease were independent risk factors for a worse IBDQ (p = 0.03, p = 0.015 and p < 0.0001). Interestingly, the median FSFI and IIEF score were not found to be significant different in any domain. CONCLUSIONS: QoL but not sexual function is significantly influenced by surgery for perianal Crohn's disease.

AIM: Endorectal advancement flaps are an established treatment for high transsphincteric and suprasphincteric fistulae. The outcome of a repeat procedure in the case of flap breakdown and fistula recurrence remains unclear. The aim of the study was to analyse the outcome of repeat endorectal advancement flaps. METHODS: We retrospectively analysed patients with a repeat endorectal advancement flap procedure after flap breakdown and recurrence of fistula-in-ano of cryptoglandular origin who had been treated in our unit between 1994 and 2010. RESULTS: In all, 97 patients underwent an endorectal advancement flap procedure for fistula-in-ano and, of these, nine patients (five men, four women, 9.3%) subsequently underwent a repeat procedure due to flap breakdown. Median age was 40 years (range 25-60). Median follow-up time was 85 months (range 26-136). Seven full-thickness and two mucosal flap repeat procedures were performed because of eight transsphincteric and one suprasphincteric fistulae. The repeat procedure was successful in seven (78%) patients. In one of the two patients with repeat flap failure, a third flap procedure failed again. Disturbances of postoperative faecal incontinence were observed in five (55%) patients. Overall, the median postoperative Vaizey faecal incontinence score was 1 (range 0-4). CONCLUSION: Repeat endorectal advancement flap procedures are feasible and associated with a low recurrence rate and mild postoperative faecal incontinence. Therefore, a repeat procedure is a viable option in the case of a flap breakdown and fistula recurrence.

BACKGROUND: Ileocecal interposition (ICI) for first-line reconstruction after low anterior colorectal resection was introduced by von Flüe and Harder in 1994 (Dis Colon Rectum 37:1160-1162, 1994). We report our experience using this technique to bridge colonic gaps after significant loss of bowel length. PATIENTS AND METHODS: Between 1999 and 2009 the left-sided colon was too short for traditional isoperistaltic reconstruction in six patients treated in our hospital. Reasons for extensive bowel loss were a deficient (n = 3) or torn (n = 1) marginal artery with ischemia or repeat colorectal resections (n = 2). An ICI was done to bridge the gap and enable restoration of intestinal continuity. RESULTS: No patient died. Whenever performing a coloanal anastomosis (4/6) a loop ileostomy was raised. One patient with colonic diversion experienced graft-related complications: ischemic colitis of the interposed colonic segment, anastomotic stenosis, and a presacral sinus were observed and managed nonoperatively. Subsequent closure of the stoma was possible in all cases. A median Vaizey incontinence score of 9 (range: 4-14) was recorded in the patient with coloanal anastomosis. The average number of bowel movements per day was 1.5 (range: 0.5-6). CONCLUSIONS: When the descending colon does not reach the rectal stump or anal canal in reoperative cases or after vascular complication, ICI is a useful salvage procedure resulting in good bowel function.

AIM: Little is known about the association of haemorrhoids and anorectal function. Moreover, available data on the impact of constipation on the presence of haemorrhoids are conflicting. The present study aimed to assess any potential relationship between haemorrhoids and anorectal dysfunction. METHOD: All participants who attended the Austrian nationwide healthcare programme for colorectal cancer screening at four medical institutions were enrolled prospectively between 2008 and 2009. A colonoscopy and detailed anorectal examination were performed on all patients. Haemorrhoids were classified according to an international grading system. Faecal incontinence was defined as the involuntary loss of solid stool, liquid stool or gas, at least once a month. Constipation was recorded by a constipation scoring system. RESULTS: Of 976 participants, 380 (38.9%) were found to have haemorrhoids. There was an association between healthy individuals, patients with symptomatic and patients with asymptomatic haemorrhoids and incontinence of liquid stool. No association was found regarding incontinence for solid stool and gas. The median constipation score was significantly higher in those patients with haemorrhoids (grade I-IV) compared with patients without haemorrhoids (2.5 points (range, 0-19) and 3 points (range, 0-19); P = 0.0113). 'Painful evacuation effort' and 'assistance for defaecation (stimulant laxatives, digital assistance or enema)' showed a significant correlation with haemorrhoids (P = 0.0394 and P = 0.0143). CONCLUSION: Although the median constipation score was low in both groups, there was a significant association between constipation and haemorrhoids in adult patients.

AIM: There are few studies into the quality of life of patients with haemorrhoids. The aim of this study was to assess the quality of life of patients with haemorrhoids in an adult general population. METHOD: Participants, who attended the Austrian nationwide healthcare programme for colorectal cancer screening at four medical institutions, were enrolled prospectively between 2008 and 2009. A colonoscopy was performed in all patients. Haemorrhoids were classified according to an international grading system and defined as symptomatic in cases with bleeding, itching, soiling or pain. Quality of life was measured by the Short Form-12 Health Survey. RESULTS: Of 976 participants, 380 patients (39%) had haemorrhoids. The median physical health score was 52.6 (range 20.6-61.3) in the symptomatic and 53.2 (range 16.2-61.3) in the asymptomatic group (P = 0.7993). The median mental health score showed also no significant difference between both groups [symptomatic group, 52.8 (range 12.4-62.6); asymptomatic group, 54.8 (range 18.7-67.2); P = 0.0738]. CONCLUSION: Haemorrhoids, irrespective of their degree, do not influence quality of life measured by the Short Form-12 Health Survey.

AIM: Endo-sponge assisted treatment (endo-sponge) represents a novel approach to treat patients with anastomotic dehiscence following anterior resection for rectal cancer. Yet, limited data are available to predict success, compatibility with radiotherapy and/or chemotherapy as well as acceptance by the patients. METHOD: Between September 2007 and June 2008, nine patients suffering from anastomotic leakage after anterior rectal resection (n = 6) or suffering from leakage of rectal stump following Hartmann's procedure (n = 3) were treated by endo-sponge. We recorded clinical outcome and patient's comfort using a 10-point visual analogue scale (VAS). RESULTS: Median time of endo-sponge treatment was 3 weeks (range: 2-8). There were no minor or major complications. In 6 (66.6%) patients, the anastomotic leakage healed successfully. Three patients showed no response and needed further surgical intervention. The lack of success was due to complexity of the leakages, which comprised either more than 270 degrees of the circumference or consisted of two distant fistulas. Formation of granulation tissue was unaffected by chemotherapy. For the question 'alteration in daily life activity', a median score of 5 (range: 1-9) was found. Measuring 'pain sensation' during endo-sponge treatment patients scored a median of 3 (range: 0-6). CONCLUSIONS: Endo-sponge treatment can be recommended as an alternative approach to treat pelvic sepsis following anastomotic dehiscence or rectal stump insufficiency. Extended leakages should be treated by different approaches having little probability of successful healing, but can lead to discomfort for the patient. Radiochemotherapy does not cause a problem for application of the endo-sponge.

AIM: There is growing evidence that stapled anastomoses are similarly effective compared to hand-sewn anastomoses in Crohn's patients. This study was designed to assess safety and limitations of wide-lumen stapled ileocolic anastomoses. METHOD: All patients with ileocolic resections for Crohn's disease perfomed between 1998 and 2006 were studied. A stapled anastomosis was constructed whenever possible. Potential risk factors for postoperative complications were recorded, retrospectively. Univariate and multivariate analyses were performed. RESULTS: In 209 out of 220 cases (95%, 132 primary operations) stapled anastomoses were performed. Eleven patients underwent a hand-sewn anastomosis owing to massive bowel dilatation (n = 7) or increased wall thickness (n = 4). There were 10 major (4.5%; surgical: 8, medical: 2) complications including two anastomotic leaks and one anastomotic bleed (all from stapled anastomoses) and one death not related to the anastomosis. Minor complications occurred in 25 patients. In multivariate analysis, major surgical postoperative complications were significantly associated with a low level of albumin (P = 0.0113) and previous resections for Crohn's disease (P = 0.0144). CONCLUSION: Stapled ileocolic anastomosis was safe in the majority of Crohn's patients. The most important limitation was technical impracticability. A low level of albumin and a history of previous resection increased the risk of postoperative complications.
