BACKGROUND/AIMS
A poor prognostic factor for Crohn's disease (CD) includes perianal fistulizing disease, including perianal fistula and/or perianal abscess. Currently, a tool to assess perianal symptoms in patients with CD remains nonexistent. This study aimed to develop a perianal fistulizing disease self-screening questionnaire for patients with CD.
METHODS
This prospective pilot study was conducted at three tertiary referral centers between January 2019 and May 2020. We formulated questions on perianal symptoms, including tenesmus, anal discharge, bleeding, pain, and heat. A 4-point Likert scale was used to rate each question. Patients with CD completed a questionnaire and underwent pelvic magnetic resonance imaging (MRI).
RESULTS
Overall, 93 patients were enrolled, with 51 (54.8%) diagnosed with perianal fistulizing disease, as determined by pelvic MRI. The Spearman correlation findings demonstrated that anal pain (p = 0.450, p < 0.001) and anal discharge (p = 0.556, p < 0.001) were the symptoms that most significantly correlated with perianal disease. For anal pain and discharge, the area under the receiver operating characteristic curve of the scores was significantly higher than that of the combined score for all five symptoms (0.855 vs. 0.794, DeLong's test p = 0.04). For the two symptoms combined, the sensitivity, specificity, and positive predictive and negative predictive values were 88.2, 73.8, 80.4, and 83.8%, respectively, with 81.7% accuracy for detecting perianal fistulizing disease.
CONCLUSION
This study indicates that simple questions regarding anal pain and discharge can help accurately identify the presence of perianal fistulizing disease in patients with CD.

Ligation of the intersphincteric fistula tract has been recently employed as definitive treatment of anal fistulas. However, it carries a potential risk of continence impairment, fistula recurrence, and repeated operations. This study aimed to assess postoperative outcomes related to this procedure and evaluate the potential influence of preoperative and intraoperative features. Patients who underwent LIFT procedure between June 2012 and September 2021 were retrospectively analyzed. Patients were divided according to whether they developed fistula recurrence and on the history of a surgery prior to the LIFT. Preoperative features, postoperative outcomes, and risk factors adverse outcomes were analyzed. Forty-eight patients were included, of which 25 received primary LIFT, being the high transsphincteric fistula pattern the most frequent (62.5%). The median follow-up was 13.3 months, with a recurrence rate of 20.8%, of which the majority presented an intersphincteric fistula pattern (50%); and continence impairment rate of 16.7%. A higher prevalence of diabetes (p = 0.026) and a trend towards a higher prevalence of patients with a history of high transsphincteric fistula (0.052) were observed in the group with fistula recurrence. The history of diabetes and the operation time with a cut-off value ≥ 69 min showed a trend as a risk factors for developing fistula recurrence (0.06) and postoperative continence impairment (0.07), respectively. The LIFT procedure seems to be safe in terms of morbidity, with a reasonable incidence of recurrences, showing better results when it is primarily performed. Preoperative characteristics should be considered as they may impact outcomes.

OBJECTIVE
Surgery for obstetric fistula is a highly effective treatment to restore continence and improve quality of life. However, a lack of data on the cost-effectiveness of this procedure limits prioritization of this essential treatment. This study measures the effectiveness of fistula surgeries using disability-adjusted life years (DALYs) averted.
METHODS
In 2021 and 2022, the Fistula Foundation funded 20 179 fistula surgeries and related procedures at 143 hospitals among 27 countries. We calculated DALYs averted specifically for vesicovaginal fistula and rectovaginal fistula procedure types (n = 13 235 surgeries) by using disability weights from the 2019 Global Burden of Disease study. We based cost calculations on direct treatment expenses, including medical supplies, health provider fees, and preoperative and postoperative care. We measured effectiveness using data on the risk of permanent disability, country-specific average life spans, and treatment outcomes.
RESULTS
The total treatment cost was $7.6 million, and a total of 131 433 DALYs were averted. Thus, the cost per DALY averted-the cost to restore 1 year of healthy life-was $58. For this analysis, we took a cautious approach and weighted only surgeries that resulted in a closed fistula with restored continence. We calculated DALYs averted by country. Limitations of the study include data entry errors inherent in patient logs and lack of long-term outcomes.
CONCLUSION
The current study demonstrates that obstetric fistula surgery, along with having a significant positive impact on maternal health outcomes, is highly cost-effective in comparison with other interventions. The study therefore highlights the benefits of prioritizing fistula treatment as part of the global agenda for maternal health care.

BACKGROUND
It is challenging to identify residual or recurrent fistulas from the surgical region, while MR imaging is feasible. The aim was to use dynamic contrast-enhanced MR imaging (DCE-MRI) technology to distinguish between active anal fistula and postoperative healing (granulation) tissue.
METHODS
Thirty-six patients following idiopathic anal fistula underwent DCE-MRI. Subjects were divided into Group I (active fistula) and Group IV (postoperative healing tissue), with the latter divided into Group II (≤ 75 days) and Group III (> 75 days) according to the 75-day interval from surgery to postoperative MRI reexamination. MRI classification and quantitative analysis were performed. Correlation between postoperative time intervals and parameters was analyzed. The difference of parameters between the four groups was analyzed, and diagnostic efficiency was tested by receiver operating characteristic curve.
RESULTS
Wash-in rate (WI) and peak enhancement intensity (PEI) were significantly higher in Group I than in Group II (p = 0.003, p = 0.040), while wash-out rate (WO), time to peak (TTP), and normalized signal intensity (NSI) were opposite (p = 0.031, p = 0.007, p = 0.010). Area under curves for discriminating active fistula from healing tissue within 75 days were 0.810 in WI, 0.708 in PEI, 0.719 in WO, 0.783 in TTP, 0.779 in NSI. All MRI parameters were significantly different between Group I and Group IV, but not between Group II and Group III, and not related to time intervals.
CONCLUSION
In early postoperative period, DCE-MRI can be used to identify active anal fistula in the surgical area.

There are several surgical options described for the treatment of anorectal fistulas, specially in complex cases where recurrence rates and the possibility of postoperative complications are still high. Laser- FiLaC™ has been described in this study as an option in the management of anorectal fistula. The aim of this study was to assess the novel radial laser probe treatment in complex fistula in-ano and report the success rate and recurrence rate. We studied retrospectively 56 patients who, according to our hospital patient records, underwent radial laser probe surgery between March 2019 and August 2020. In a mean follow-up time of 6 months, the success rate at 2 months was 86.0%. Most operations were done under spinal anesthesia. The recovery time was rapid and median sick leave was 7 days. Of those initially successfully treated, 3.0% developed a recurrence. Altogether 4.0% of the patients underwent a re-operation. There is a good success rate using FiLaC™ treatment. FiLaC™ is very effective in treatment of complex fistula and as well as recurrence of fistula. It has a short hospital stay and as well as it is painless surgical technique that should be largely used in our country.

BACKGROUND
Ileal pouch-anal anastomosis (IPAA) is considered the preferred restorative surgical procedure for patients with ulcerative colitis and familial adenomatous polyposis requiring proctocolectomy. Unfortunately, postoperative leaks remain a complication with potentially significant ramifications. This study aimed to provide a comprehensive description of the evaluation, management, and outcomes of leaks after primary IPAA procedures.
METHODS
Between 1995 and 2022, a total of 4058 primary IPAA procedures were performed at Cleveland Clinic. From a prospectively maintained pouch registry, we retrospectively reviewed the data of 237 patients who presented to the pouch center for management. Of these, 114 (3%) had undergone the index IPAA procedure at our clinic (de novo cases), whereas 123 patients had their index IPAA performed elsewhere. Data were missing for 43 patients, resulting in a final cohort of 194 patients.
RESULTS
Our cohort had an average age of 41 years (range, 16-76) at the time of leak diagnosis. Overall, 55.2% were males, average body mass index was 24.4 kg/m, and pain was the most prevalent presenting symptom (61.8%), followed by fever (34%). Leaks were confirmed through diagnostic testing in 141 cases, whereas 27.3% were detected intraoperatively. The most common initial diagnoses were pelvic abscess (47.4%) and enteric fistulas (26.8%), including cutaneous (9.8%), vaginal (7.2%), and bladder fistulas (3.1%). By location, leaks occurred at the tip of the "J" (52.6%), at the pouch-anal anastomotic site (35%), and in the body of the pouch (12.4%). A nonoperative management approach was initially attempted in 49.5% of cases, including antibiotic therapy, drainage, endoclip, and endo-sponge, with a success rate of 18.5%. Surgery was eventually required in 81.4% of patients, including (1) sutured or stapled pouch repair (52.5%), with diversion performed in 87.9% of these cases either before or during the salvage surgery; (2) pouch excision with neo-IPAA (22.7%), including 9 patients from the first group; and (3) pouch disconnection, repair, and reanastomosis (9.3%). Pouch failure occurred in 8.4%, with either pouch excision (11.1%) or permanent diversion (4.5%). Ultimately, 12.4% of patients (24 of 194) required permanent diversion, with all necessitating pouch excision. In the 30-day follow-up after salvage surgery, short-term complications arose in 38.7% of patients. The most common complications observed were ileus, pelvic abscess/sepsis, and fever.
CONCLUSION
Leaks after primary IPAA procedures represent an infrequent, yet challenging, complication. Despite attempts at nonoperative management, the success rate is limited. Salvage surgery is associated with a high pouch retention rate, underscoring its importance in the management of post-IPAA leaks.

BACKGROUND
Complex anal fistula has a high recurrence rate and disturbing surgical complications, which are frustrating for patients and challenging for surgeons. Although single or combined management methods have produced positive outcomes, no trials have simultaneously compared these therapies. Therefore, this study aimed to determine the management method for complex anal fistula with the lowest failure and complication rates.
METHODS
This network meta-analysis (NMA) was registered in the international prospective register of systematic reviews (PROSPERO; CRD42023393349). Randomized controlled trials that analyzed complex anal fistula management were obtained from Medline, Scopus, and Cochrane using representative keywords. The primary outcome was the failure of anal fistulas to heal (including recurrences) after 6 to 12 months. The secondary outcome was fecal incontinence. All statistical analysis was conducted within the Bayesian framework using BUGSnet 1.1.0 in R Studio. A forest plot and league table were used to present the results.
RESULTS
A total of 19 studies containing 15 interventions, 1844 subjects, and 104 pairwise comparisons were analyzed quantitatively. The lowest failure rates occurred with ligation of the intersphincteric fistula tract (LIFT) + Plug (RR 0.2; 95 % CI 0.01-2.65), LIFT + platelet-rich plasma (PRP) (RR 0.22; 95 % CI 0.01-2.89), and FSR (RR 0.26; 95 % CI 0.02-2.12) relative to drainage seton. LIFT combined with other management methods showed lower fecal incontinence rates than the other treatments.
CONCLUSION
The combination of LIFT with plug or PRP resulted in lower failure and complication rates in the management of complex anal fistula compared to the other methods tested.

Inflammatory increased metabolic activity was discovered in the left anal canal on an 18 F-FDG PET/CT scan performed for initial staging of anal squamous cell carcinoma in a patient with history of perianal Crohn disease. This increased uptake was due to a complex intersphincteric perianal fistula with supralevator extension, with a secondary, contiguous, superficial focus of squamous cell carcinoma at the anal verge that was identified on an MRI performed on the same day.

AIM
Pelvic radiotherapy is limited by dose-dependent toxicity to surrounding organs. The aim of this prospective study was to evaluate the efficacy and safety of intrarectal formalin treatment for radiotherapy-induced haemorrhagic proctopathy (RHP) at the Royal Marsden Hospital.
METHOD
Adult patients were enrolled. Haemoglobin was evaluated before and after formalin treatment. Antiplatelet and/or anticoagulation treatment and administration of transfusion were recorded. The interval between completion of radiotherapy and the first intrarectal 5% formalin treatment was assessed and the dose of radiotherapy was evaluated. Clinical assessment of the frequency and amount of rectal bleeding (rectal bleeding score 1-6) and endoscopic appearance (grade 0-3) were classified. Complications were recorded.
RESULTS
Nineteen patients were enrolled, comprising 13 men (68%) and 6 women. The mean age was 75 ± 9 years. The median time between completion of radiotherapy and the first treatment was 20 months [interquartile range (IQR) 15 months] and the median dose of radiotherapy was 68 Gy (IQR 14 Gy). Thirty-two procedures were performed (average 1.7 per patient). In total, 9/19 (47%) patients were receiving anticoagulation and/or antiplatelet medication and 5/19 (26%) received transfusion prior to treatment. The mean value of serum haemoglobin before the first treatment was 110 ± 18 g/L and afterwards it was 123 ± 16 g/L (p = 0.022). The median rectal bleeding score before the first treatment was 6 (IQR 0) and afterwards 2 (IQR 1-4; p < 0.001), while the median endoscopy score on the day of first treatment was 3 (IQR 0) compared with 1 (IQR 1-2) on the day of the last treatment 1 (p < 0.001). One female patient with a persistent rectal ulcer that eventually healed (18 months of healing) subsequently developed rectovaginal fistula (complication rate 1/19, 5%).
CONCLUSIONS
Treatment with intrarectal formalin in RHP is effective and safe.
