Abstract
PDF
- Anal fistula can be a challenging condition to manage, with complex fistulas presenting even greater difficulties. The primary concerns in treating this condition are a risk of damage to the anal sphincters, which can compromise fecal continence, and refractoriness to treatment, as evidenced by a high recurrence rate. Furthermore, the treatment of complex anal fistula involves several additional challenges. Satisfactory solutions to many of these obstacles remain elusive, and no consensus has been established regarding the available treatment options. In summary, complex anal fistula has no established gold-standard treatment, and the quest for effective therapies continues. This review discusses and highlights groundbreaking advances in the management of complex anal fistula over the past decade.

Abstract
PDF
- Purpose
This study assessed the long-term outcomes and quality of life in patients who underwent sacral neuromodulation (SNM) due to low anterior resection syndrome (LARS).
Methods
This single-center retrospective study, conducted from 2005 to 2021, included 30 patients (21 men; median age, 70 years) who had undergone total mesorectal excision with stoma closure and had no recurrence at inclusion. All patients were diagnosed with LARS refractory to conservative treatment. We evaluated clinical and quality-of-life outcomes after SNM through a stool diary, Wexner score, LARS score, the Fecal Incontinence Quality of Life (FIQL) questionnaire, and EuroQol-5D (EQ-5D) questionnaire.
Results
Peripheral nerve stimulation was successful in all but one patient. Of the 29 patients who underwent percutaneous nerve evaluation, 17 (58.62%) responded well to SNM and received permanent implants. The median follow-up period was 48 months (range, 18–153 months). The number of days per week with fecal incontinence episodes decreased from a median of 7 (range, 2–7) to 0.38 (range, 0–1). The median number of bowel movements recorded in patient diaries fell from 5 (range, 4–12) to 2 (range, 1–6). The median Wexner score decreased from 18 (range, 13–20) to 6 (range, 0–16), while the LARS score declined from 38.5 (range, 37–42) to 19 (range, 4–28). The FIQL and EQ-5D questionnaires demonstrated enhanced quality of life.
Conclusion
SNM may benefit patients diagnosed with LARS following rectal cancer surgery when conservative options have failed, and the treatment outcomes may possess long-term sustainability.

Abstract

- Purpose
Many methods have been used to treat complex fistulas, but no single technique has been considered standard. Damage to the sphincter may sometimes be unavoidable, and incontinence may be an important cause of morbidity. This study aimed to validate the results of transanal opening of the intersphincteric space (TROPIS), as a technique that avoids damaging the anal sphincter, in patients with complex fistula in ano.
Methods
A prospective study was conducted among 35 consecutive patients with complex fistula in ano. After a preoperative magnetic resonance fistulogram, TROPIS was performed in all patients. The St. Mark’s incontinence score was assessed preoperatively and postoperatively at 3 months.
Results
The tracts were intersphincteric in 16 patients, transsphincteric in 10, extrasphincteric in 2, and horseshoe in 3. Four patients had recurrent tracts (3 transsphincteric and 1 intersphincteric). A defined follow-up schedule was used. Curettage was done if postoperative pus drainage from the wound was noted. The fistula healed in 29 patients (82.89%) following TROPIS. The remaining 6 patients received curettage, with healing in 3 (overall healing rate, 91.4%). Patients who received curettage were followed for 3 months, and the outcome was labeled as healed or failed. The mean preoperative incontinence score was 0. One patient developed incontinence to gas postoperatively in week 2, but there was no significant change in the scores at 3 months postoperatively. The mean postoperative incontinence score was 0.02.
Conclusion
TROPIS is an effective method for the treatment of complex fistula in ano, with minimal risk for incontinence.

Abstract

- Fecal incontinence (FI) has a significant long-term impact on patient quality of life for which there is a range of medical and surgical management alternatives. We report the preliminary outcome using the ForConti Contix Faecal Incontinence Management System (FIMS) in FI patients who had failed conservative therapy and who were recruited at 2 tertiary institutions between September 2018 and September 2020. Comparative assessments were made before and after 2 week periods of treatment using bowel diaries and subjective Wexner and Faecal Incontinence Quality of Life scores. Of 17 patients enrolled, 11 completed an 8-week assessment with a significant fall in the average percentage of FI days reported from 84% before treatment to 16.8% at the first posttreatment assessment and down to 13.2% by the second assessment period. This finding correlated with a similar reduction in the total weekly number of episodes of frank FI, minor soiling, and fecal urgency reported by patients along with concomitant improvements in the Wexner scores. For those using the device, there was less concern about accidental bowel leakage, high rates of satisfaction, and minimal problems with the device. Initial results are encouraging warranting further study.

Abstract
PDF
- Juvenile polyps (JPs) are the most common polyps in pediatric patients. We present the case of an 18-year-old male patient with a giant solitary JP resembling solitary rectal ulcer syndrome (SRUS). The presenting history was rectal bleeding and symptoms of obstructed defecation syndrome. Colonoscopy revealed a polypoidal mass at the anorectal junction, with biopsy-confirmed SRUS. The symptoms worsened, and a protruding mass from the anus caused fecal incontinence. Pelvic magnetic resonance imaging showed a huge pedunculated mass occupying the low rectum with local compression of the urinary bladder. Transanal excision of the anal tumor was performed due to bleeding. A histopathological examination showed a JP with high-grade dysplasia. A histological examination to differentiate JPs and SRUS could be challenging based on a superficial forceps biopsy. Therefore, an excision biopsy is usually warranted with the understanding that adenomatous or malignant transformation is found in 5.6% to 12% of all JPs.

Abstract
PDF
- Purpose
Complex anal fistulas can recur after clinical healing, even after a long interval which leads to significant anxiety. Also, ascertaining the efficacy of any new treatment procedure becomes difficult and takes several years. We prospectively analyzed the validity of Garg scoring system (GSS) to predict long-term fistula healing.
Methods
In patients operated for cryptoglandular anal fistulas, magnetic resonance imaging was performed preoperatively and at 3 months postoperatively to assess fistula healing. Scores as per the GSS were calculated for each patient at 3 months postoperatively and correlated with long-term healing to check the accuracy of the scoring system.
Results
Fifty-seven patients were enrolled, but 50 were finally included (7 were excluded). These 50 patients (age, 41.2±12.4 years; 46 men) were followed up for 12 to 20 months (median, 17 months). Forty-seven patients (94.0%) had complex fistulas, 28 (56.0%) had recurrent fistulas, 48 (96.0%) had multiple tracts, 20 (40.0%) had horseshoe tracts, 15 (32.0%) had associated abscesses, 5 (10.0%) were suprasphincteric, and 8 (16.0%) were supralevator fistulas. The GSS could accurately predict long-term healing (high positive predictive value, 31 of 31 [100%]) but was not very accurate in predicting nonhealing (negative predictive value, 15 of 19 [78.9%]). The sensitivity in predicting healing was 31 of 35 (88.6%).
Conclusion
GSS accurately predicts long-term fistula with a high positive predictive value (100%) but is less accurate in predicting nonhealing. This scoring system can help allay anxiety in patients and facilitate the early validation of innovative procedures for anal fistulas.

Abstract
PDF
- The complexity in the molecular mechanism of the internal anal sphincter (IAS) limits preclinical or clinical outcomes of fecal incontinence (FI) treatment. So far, there are no systematic reviews of IAS translation and experimental studies that have been reported. This systematic review aims to provide a comprehensive understanding of IAS critical role in FI. Previous studies revealed the key pathway for basal tone and relaxation of IAS in different properties as follows; calcium, Rho-associated, coiled-coil containing serine/threonine kinase, aging-associated IAS dysfunction, oxidative stress, renin-angiotensin-aldosterone, cyclooxygenase, and inhibitory neurotransmitters. Previous studies have reported improved functional outcomes of cellular treatment for regeneration of dysfunctional IAS, using various stem cells, but did not demonstrate the interrelationship between those results and basal tone or relaxation-related molecular pathway of IAS. Furthermore, these results have lower specificity for IAS-incontinence due to the included external anal sphincter or nerve injury regardless of the cell type. An acellular approach using bioengineered IAS showed a physiologic response of basal tone and relaxation response similar to human IAS. However, in both cellular and acellular approaches, the lack of human IAS data still hampers clinical application. Therefore, the IAS regeneration presents more challenges and warrants more advances.

Abstract

- Purpose
Anastomotic leak (AL) is an uncommon but potentially devastating complication after rectal resection. We aim to provide an updated assessment of bowel function and quality of life after AL, as well as associated short- and long-term outcomes.
Methods
A retrospective audit of all rectal resections performed at a colorectal unit and associated private hospitals over the past 10 years was performed. Relevant demographic, operative, and histopathological data were collected. A prospective survey was performed regarding patients’ quality of life and fecal continence. These patients were matched with nonAL patients who completed the same survey.
Results
One hundred patients (out of 1,394 resections) were included. AL was contained in 66.0%, not contained in 10.0%, and only anastomotic stricture in 24.0%. Management was antibiotics only in 39.0%, percutaneous drainage in 9.0%, operative abdominal drainage in 19.0%, transrectal drainage in 6.0%, combination of percutaneous drainage and transrectal drainage in 2.0%, and combination abdominal/transrectal drainage in 1.0%. The 1-year stoma rate was 15.0%. Overall, mean Fecal Incontinence Severity Instrument scores were higher for AL patients than their matched counterparts (8.06±10.5 vs. 2.92±4.92, P=0.002). Patients with an AL had a mean EuroQol visual analogue scale (EQ-VAS) of 76.23±19.85; this was lower than the matched mean EQ-VAS for non-AL patients of 81.64±18.07, although not statistically significant (P=0.180).
Conclusion
The majority of AL patients in this study were managed with antibiotics only. AL was associated with higher fecal incontinence scores in the long-term; however, this did not equate to lower quality of life scores.

Abstract

- Purpose
Bowel dysfunction commonly occurs in patients with locally advanced rectal cancer treated with a multimodal approach of chemoradiation therapy (CRT) combined with sphincter-preserving rectal resection. This study investigated the decline in anorectal function using sequential anorectal manometric measurements obtained before and after the multimodal treatment as well as at a 1-year follow-up.
Methods
This was a retrospective cohort study conducted in a single center. The study population consisted of patients with locally advanced mid- to low rectal cancer who received the preoperative CRT followed by sphincter-preserving surgery from 2012 to 2016. The anorectal manometric value measured after each treatment modality was compared to demonstrate the degree of decline in anorectal function. A generalized linear model of repeated measures was performed using the manometric values measured pre- and post-CRT, and at 12 months postoperatively.
Results
Overall, 100 patients with 3 consecutive manometric data were included in the final analysis. In the overall cohort study, the mean resting and maximal squeezing pressures showed insignificant decrement post-neoadjuvant CRT. At a 1-year postoperative follow-up, the maximal squeezing pressure significantly decreased. The maximal rectal sensory threshold demonstrated significant reduction consecutively after each following treatment (P<0.001).
Conclusion
The short-term effect of neoadjuvant CRT on the anal sphincters was relatively trivial. The following sphincter-saving surgery resulted in a profound disruption of the anorectal function. Patients with rectal cancer should be consulted on the consequence of multimodal treatment.

- Purpose
Perianal injection of bulking agents is an attractive treatment option for patients with mild to moderate fecal incontinence (FI). Various bulking agents have been used for injection therapy, but the optimal injection materials and methods are yet to be standardized. This study aimed to evaluate the effects of injection therapy using aluminum potassium sulfate and tannic acid (ALTA) in the management of FI.
Methods
This study included consecutive patients who underwent ALTA injection therapy for FI at our institution. The procedure was performed with the patient in the jackknife position, under caudal epidural anesthesia. The procedure consisted of a 4-step injection to the 3 main cushions and a multipoint injection to the remaining submucosa of the anal canal.
Results
Seventy-seven patients (mean age, 76 years) were enrolled in the study. The mean Cleveland Clinic incontinence score of 11.9 ± 4.1 at baseline significantly improved to 7.3 ± 5.2 at 3 months following treatment. The mean maximal resting pressure also increased significantly 3 months after the intervention. Postoperative complications were observed in 3 patients (3.9%), and all events were mild. The mean duration of postoperative follow-up was 17.5 months. The cumulative recurrence-free rate at 3 years was 72.4%.
Conclusion
ALTA injection for FI is safe, easy to perform, and provides reasonable mid-term outcomes. Moreover, concomitant anorectal diseases that may be contraindicated by other injectable bulking agents could be treated simultaneously. Therefore, ALTA injection is a promising alternative in the absence of other injectable agents.

Abstract

- Purpose
Anal fissure is a common anorectal condition, yet its pathogenesis remains unclear. Lateral internal sphincterotomy (LIS) is the gold standard treatment for chronic anal fissures that do not respond to conservative treatment; however, it has a risk of anal incontinence. We believe that fibrosis of the internal anal sphincter is an important factor in the pathogenesis of chronic anal fissure. In this study, we describe the minimal LIS method, a minimally invasive method where only the fibrotic portion of the internal anal sphincter is cut. We also describe the outcomes of this method.
Methods
We performed a retrospective review of 468 patients (270 male and 198 female) who underwent minimal LIS for chronic anal fissure in 2017 at Seoul Song Do Hospital. We analyzed the patients’ clinical characteristics, manometry data, complications, and outcomes of minimal LIS. The outcomes of the surgery were assessed via questionnaires during the postoperative outpatient visits, beginning 2 weeks postoperatively.
Results
The overall complication rate was 4.0% (19 patients). Delayed healing occurred in 14 patients (3.0%), perianal abscess was present in 3 patients (0.6%), and gas incontinence occurred in 2 patients (0.4%). All complications were improved with conservative treatment. Recurrence, defined as the recurrence of anal fissure more than 4 weeks after healing, was present in 6 patients (1.3%).
Conclusion
Minimal LIS is a safe and effective treatment option for patients with chronic anal fissure. Postoperative complications, especially incontinence and recurrence, are rare.

Abstract

- Purpose
This study was performed to evaluate the long-term evolution of continence and patient’s quality of life after surgical treatment for obstetric fecal incontinence.
Methods
A prospective longitudinal study was conducted including consecutive patients who underwent sphincteroplasty for severe obstetric fecal incontinence. The first phase analyzed changes in continence and impact on quality of life. The second phase studied the long-term evolution reevaluating the same group of patients 6 years later. Degree of fecal incontinence was calculated using the Cleveland Clinic Score (CCS). Quality of life assessment was carried out with the Fecal Incontinence Quality of Life scale.
Results
Thirty-five patients with median age of 55 years (range, 28 to 73 years) completed the study. Phase 1 results: after a postoperative follow-up of 30 months (4 to 132 months), CCS had improved significantly from a preoperative of 15.7 ± 3.1 to 6.1 ± 5.0 (P < 0.001). Phase 2 results: median follow-up in phase 2 was 110 months (76 to 204 months). The CCS lowered to 8.4 ± 4.9 (P = 0.04). There were no significant differences between phases 1 and 2 in terms of quality of life; lifestyle (3.47 ± 0.75 vs. 3.16 ±1.04), coping/behavior (3.13 ±0.83 vs. 2.80 ±1.09), depression/self-perception (3.65 ±0.80 vs. 3.32 ± 0.98), and embarrassment (3.32 ± 0.90 vs. 3.12 ± 1.00).
Conclusion
Sphincteroplasty offers good short-medium term outcomes in continence and quality of life for obstetric fecal incontinence treatment. Functional clinical results deteriorate over time but did not impact on patients’ quality of life.

Abstract
PDF
- Purpose
For the past several decades, internal anal sphincterotomy has generally been considered to be the standard operation for an anal fissure. However, wound complications inherent in this operation forced surgeons to look for an alternative form of treatment. The aim of our study was to evaluate the long-term outcome of anal dilatation for chronic anal fissure, especially possible negative impact on anal sphincter function.
Methods
The study was approved by the local Institutional Review Board and given a waiver of written consent. A phone call survey was undertaken among a group of consecutive patients who had an anal dilatation by standardized technique for chronic anal fissure for the period between 2000 and 2016. The survey included medical, obstetrical and surgical-related data, Wexner fecal incontinence score, recurrence of the anal fissure, and the need for additional medical intervention. Five hundred 48 patients were identified after limitations of age, concomitant pathology, and procedures that were applied to the hospital computerized database. Eighty-five patients (group A) agreed to participate in the survey and 463 patients did not.
Results
There were no differences between groups in demographic information and medical records data; therefore, group A may well represent a satisfactory sample of the whole group. The interval between the procedure and the survey was 6.8 ± 2.7 years. The Wexner incontinence score was 0 in 94% of patients.
Conclusion
Anal dilatation, performed in a systematic and standardized way, has a successful outcome with no complications and has no clear long-term negative impact on anal sphincter function.

Abstract

- Purpose
Propiverine hydrochloride (PH) is widely used for the treatment of urinary incontinence (UI) due to bladder overactivity. Moreover, the comorbidity of UI with fecal incontinence (FI) is known to be due to the relationship of both to nervous system disorders and dysfunction or weakening of the pelvic floor muscles. The aim of this single-arm prospective study was to evaluate the therapeutic value of PH for FI.Methods: Patients (n = 24) who were diagnosed as having both FI and UI from April 2015 to November 2016 were included in the study and administered a dosage of 10–20 mg PH every day for 1 month. The primary endpoint was to create a reduction in the frequency of FI per week. An evaluation criterion of ≥50% reduction in frequency was determined as effective. The percentage of the patients who achieved the ≥50% endpoint (responders) was also calculated.Results: The frequency of FI per week was 6.0 ± 8.2 (0.25–30) at baseline and reduced to 1.6 ± 2.1 (0–7) at the posttherapeutic state (P = 0.005). A reduction of ≥50% was seen in 14 of the patients (58.3%).Conclusion: PH reduced the frequency of FI in patients with both FI and UI. This study introduces a possible therapeutic option for the pharmacological treatment of FI.

Abstract
PDF
- Despite significant advancements in the field of medicine, management of complex obstetric perineal injuries remains a challenge. Although several surgical techniques have been described, no techniques have provided satisfactory long-term results. Recently, a perineal transposed antropyloric valve has been used for anorectal reconstruction in patients with damaged or excised anal sphincters. We describe this technique in the case of complex obstetric perineal trauma with extensive tissue loss, presenting with end stage fecal incontinence. The functional outcome after this procedure was evaluated. The patient tolerated the surgery well, and there were no procedure-related upper gastrointestinal disturbances. Short-term functional outcomes were encouraging. At the 36-month follow-up, the patient’s neoanal resting and squeeze pressures were 50 and 70 mmHg, respectively. The postoperative St. Mark’s incontinence score was 7. Perineal antropyloric valve transposition is feasible and can be successfully applied in the management of end-stage fecal incontinence associated with complex obstetric perineal injury.
