Fissurectomy with mucosal advancement flap anoplasty: The end of a dogma?

INTRODUCTION: The goal was to compare fissurectomy with mucosal advancement flap anoplasty to fissurectomy alone in the surgical treatment of anal fissure. PATIENTS AND METHODS: This study included patients who underwent surgery in 2019 for solitary, idiopathic, non-infected, posterior anal fissure, after failure of medical treatment. The choice to perform advancement flap anoplasty was based on surgeon preference and did not depend on the fissure itself. The main endpoint was the time to relief of pain. RESULTS: Of 599 fissurectomies performed during the study period, 226 patients (37.6% women, mean age 41.7±12.0 years old) underwent fissurectomy alone (n=182) or associated with advancement flap anoplasty (n=44). The two groups differed as to their sex ratio (33.5 vs. 54.5% women, P=0.01), body mass index (25.3±4.0 vs. 23.6±3.9, P=0.013) and Bristol score (3.2 vs. 3.4, P=0.038). Time to relief of pain, time to disappearance of bleeding and time to healing were 1.1 (0.5-2.3), 1.0 (0.5-2.1) and 2.0 (1.1-3.6) months, respectively. The rate of healing was 93.8% and the complication rate was 6.2%. The differences between the two groups for these outcomes were not statistically significant. The risk factors associated with absence of healing were age ≥ 40 years (Odds ratio (OR): 3.84; 95% CI, 1.12-17.68) and pre-surgical duration of fissure<35.6 weeks (OR: 6.54; 95% CI: 1.69-43.21). CONCLUSION: Mucosal advancement flap anoplasty does not provide any added value to fissurectomy alone.

Extensive suppuration and being overweight are factors associated with the failure of laser treatment for pilonidal disease: lessons from the first French retrospective cohort.

BACKGROUND: The aim of our study was to assess the efficacy of sinus laser therapy (SiLaT) for the treatment of pilonidal disease. METHODS: All adult patients treated with SiLaT in our department between June 1, 2018, and August 23, 2019, were included in the study. Success was defined as the closure of cutaneous orifices and the absence of discharge or abscesses. RESULTS: We included 29 consecutive patients (22 males) with a median age of 32.5 ± 10.5 years. Eight patients had already undergone prior surgery for pilonidal disease. The procedure was performed under spinal (55%) or general (45%) anesthesia. The mean follow-up was 370.3 days (± 165.8 days). We observed 2 primary failures (6.9%) and 7 recurrences (24.1%). Ultimately, 20 patients were considered to have been cured (69%). The mean time to healing was 25 days (± 8.1 days). No serious complications were reported. Usual activities were resumed within a mean of 4.9 days (± 7.2), and 86% of patients reported being "very satisfied" with the treatment. The body mass index was lower for patients who were cured (24.0 ± 3.6) than for those who experienced treatment failure (27.6 ± 3.4; p = 0.018). The cured patients were less likely to have one or more secondary openings (35.0 versus 88.9%, p = 0.014). CONCLUSIONS: Almost 70% of our patients were cured by SiLaT. Complications were rare and mild. The technique appeared to be less effective for overweight patients and those with one or more secondary openings associated with pilonidal pits.

Hemorrhoidal surgery in patients with IBD: caution is the parent of safety.

BACKGROUND: The aim of this study was to evaluate the outcome of hemorrhoidal surgery in patients with inflammatory bowel disease (IBD) undergoing surgery at our center. METHODS: All adult patients with IBD undergoing hemorrhoidal surgery in our department between November 1, 2013 and July 7, 2020 were included in the study. At the time of surgery, the patients' IBD was in clinical, biological and endoscopic remission, and none of the patients had specific primary anoperineal lesions. RESULTS: We included 25 patients (48% female) with a mean age 48 years (± 13.1 years). There were 13 cases of CD (52%) and 12 of ulcerative colitis (UC). Pharmacological and instrumental hemorrhoidal treatment had failed in all patients. The CD lesions were exclusively ileal (77%) or ileocolic (23%). The surgical procedures performed for CD were mono-hemorrhoidectomy in three patients (21.4%), tripedicular hemorrhoidectomy in six patients (42.9%), and artery ligations with mucopexy in five patients (35.7%). UC was rectal (16.7%), rectosigmoid (66.7%), or pancolic (16.6%). The surgical procedures performed for UC were a tripedicular hemorrhoidectomy in ten patients (83.3%) and artery ligations with mucopexy in two patients (16.7%). The mean duration of postoperative follow-up was 15.1 months. None of the patients was lost to follow-up. The mean time to wound healing after resection was 71.1 days (± 21 days) for patients with CD and 56.9 days (± 6.7 days) for patients with UC (p = 0.05). Postoperative complications were reported for four patients with CD (28.8%) and two patients with UC (16.7%). There was no suppuration, stenosis, or anal incontinence sequelae. CONCLUSIONS: Hemorrhoidal surgery resulted in a non-negligible frequency of complications in our series of IBD patients, especially in those with CD. Caution is, therefore, still necessary in this patient population.

The optimal indication for FiLaC® is high trans-sphincteric fistula-in-ano: a prospective cohort of 69 consecutive patients.

BACKGROUND: The aim of our study was to prospectively evaluate the effectiveness of the Fistula Laser Closure (FiLaC®) technique in patients at high risk of anal incontinence and to determine the predictors of success and the impact of the procedure on anal continence. METHODS: A prospective study was conducted on all patients treated with FiLaC® in our department in May 2016-April 2017, because they were at high risk of anal incontinence after fistulotomy, The fistula was considered healed when the internal and external openings were closed and the patient experienced was no pain or leakage. RESULTS: A total of 69 consecutive patients (34 males) with a median age of 40 years (33-53 years) were included in the study. One patient was lost to follow up. The fistulas were intersphincteric (3%), low (15%) or high (66%) trans-sphincteric, and suprasphincteric (16%). After a median follow-up period of 6.3 months (4.2-9.3), fistula healing was observed in 31 patients (45.6%). In univariate analysis, high trans-sphincteric fistulas (p = 0.007) and age over 50 years (p = 0.034) were significantly associated with healing. In multivariate analysis, only high trans-sphincteric fistulas were a predictive factor of significant success. No new cases of anal incontinence or any worsening in case of pre-existing anal incontinence were observed during follow-up. CONCLUSIONS: FiLaC® is particularly effective in cases of high trans-sphincteric fistulas (60% cure). This technique seems to be the most promising sphincter-saving technique available for this indication.

Online training on how to diagnose anoperineal lesions of Crohn's disease: Do pictures matter? A nationwide randomized study.

Any gastroenterologist must be trained to properly diagnose anoperineal lesions in patients with Crohn's disease (APLOC). The aim of this study was to establish whether adding pictures would improve teaching effectiveness of the diagnosis of APLOC to French gastroenterology trainees. METHOD: Trainees were asked to answer a first web-based survey consisting of evaluating 12 pictures of APLOC with a closed answer questionnaire. They were then randomized in 2 groups. Group A received an online teaching with typical pictures and APLOC definitions and group B definitions only. Trainees were asked again seven days later to answer a second survey with 12 other pictures of APLOC and 14 experts also answered this survey. Diagnostic scores were expressed in %. The primary endpoint was the comparison of the score of survey 2 between the two groups of trainees. Secondary endpoints were to compare results of survey 2 between trainees of both groups and experts, and assess diagnosis of each lesion. RESULTS: Two hundred fourty eight trainees among 465 answered survey 1, and 195 survey 2. The diagnostic score was 71.9% for groups A and B and 74.6% for experts (differences NS). After training diagnosis of ulceration was 72% for group A and 72.9% for group B, fistulae 85.2% versus 85.8%, erythema 44.1% vs. 55.6%, anoperineal scars 67.5% vs. 65.6%, and abscess 100% (differences NS). CONCLUSION: There was no difference between the two teaching methods. Further research should be performed aiming at improving teaching material and quotation baremes.

How to manage anal ulcerations and anorectal stenosis in Crohn's disease: algorithm-based decision making : French National Working Group Consensus 2018.

The French National Society of Coloproctology established national recommendations for the treatment of anoperineal lesions associated with Crohn's disease. Treatment strategies for anal ulcerations and anorectal stenosis are suggested. Recommendations have been graded following international recommendations, and when absent professional agreement was established. For each situation, practical algorithms have been drawn.

Management of anoperineal lesions in Crohn's disease: a French National Society of Coloproctology national consensus.

The French National Society of Coloproctology established national recommendations for the treatment of anoperineal lesions associated with Crohn's disease. Treatment strategies for acute abscesses, active fistulas (active denovo and still active under treatment), fistulas in remission, and rectovaginal fistulas are suggested. Recommendations have been graded following the international recommendations, and when absent, professional agreement has been established. For each situation, practical algorithms have been drawn.

Sphincter-sparing techniques for fistulas-in-ano.

Anal fistulas require surgical treatment to cure the fistula. Fistulotomy is the treatment of choice because of its high success rate, but it also carries a risk of postoperative incontinence. Different methods have been proposed to overcome the need for dividing part or all of the sphincter, so-called "sphincter saving techniques" (SST), such as flap advancement, intrafistular injection of glue, or the insertion of a bio-prosthesis (collagen plug). However, the success rate of SSTs is lower than that of fistulotomy. Ligation of the Intersphincteric Fistula Tract (LIFT) is one of the most recent SSTs. It aims to ligate and transect the fistula by an approach through the intersphincteric space. The methodological quality of most published studies has been only average, but several studies have reported attractive success rates of 70 to 95% without postoperative incontinence. Other techniques such as endo-anal clip or injection of autologous stem cells are still anecdotal.

The usefulness of microscopic bile examination in patients with suspected microlithiasis: a prospective evaluation.

Gallbladder bile collected by duodenal intubation or during surgery was examined microscopically in patients who were free of stones and in patients with proven stones. None of the 16 patients free of stones had cholesterol monohydrate crystals or calcium bilirubinate granules in bile. Among the 17 patients with proven cholelithiasis, 13 with cholesterol stones had cholesterol monohydrate crystals in their bile, but only 2 of the 4 patients with pigment stones had calcium bilirubinate granules. These data confirm that cholesterol monohydrate crystals are sensitive and specific for cholesterol stones, whereas calcium bilirubinate granules lack sensitivity for the diagnosis of pigment stones. From these results, the diagnostic usefulness of microscopic examination of bile collected from the duodenum was studied prospectively in 46 patients with symptoms suggestive of cholelithiasis but in whom stones had not been visualized at cholecystography and ultrasonography. In 15 of them, bile was found to be abnormal: cholesterol monohydrate crystals were seen in 11, cholesterol crystals + calcium bilirubinate granules in 2 and calcium bilirubinate granules in 2. To date, nine of these patients have been operated on: 6 (all with cholesterol monohydrate crystals) had small cholesterol gallstones and 3 (2 with cholesterol monohydrate crystals and 1 with calcium bilirubinate granules) had signs strongly suggestive of the recent migration of gallstones. One patient refused operation, but minute pigment stones were found to be associated with calcium bilirubinate granules at duodenal intubation. In the other 31 patients, bile contained neither cholesterol monohydrate crystals nor calcium bilirubinate granules. They were not operated on and were followed up with repeated investigations for 12 to 24 months.(ABSTRACT TRUNCATED AT 250 WORDS)
