Little is known about the long-term functional outcomes of restorative proctocolectomy.The aim of this study was to examine ileoanal pouch outcomes 20 and 30 years postoperatively.This is a retrospective case series.This study was conducted at a tertiary care referral center.Patients who underwent restorative proctocolectomy between 1980 and 1994 were identified. Those with ≥20 years of in-person follow-up were included.Pouch function, pouchitis, anal stricture, and pouch failure rates were analyzed.A total of 203 patients had ≥20 years of follow-up. Of those, 71 had ≥30 years of follow-up. Initial diagnoses included ulcerative colitis (83%), indeterminate colitis (9%), familial adenomatous polyposis (4%), and Crohn's disease (3%). Twenty-one percent of those with ulcerative or indeterminate colitis later transitioned to Crohn's disease. Mean daily stool frequency was 7 (IQR 6-8), 38% experienced seepage, 31% had anal stenosis, 47% experienced pouchitis, and 18% had pouch failure. Over time, stool frequency increased in 41% of patients, stayed the same in 43%, and decreased in 16%. Patients older than 50 years at the time of construction had more daily bowel movements (median 8 vs 6; p = 0.02) and more seepage (77% vs 35%; p = 0.005) than those younger than 50 years. Patients with Crohn's disease had higher stool frequency (median 8 vs 6; p0.001) and higher rates of anal stenosis (44% vs 26%; p = 0.02), pouchitis (70% vs 40%; p0.001), and pouch failure (38% vs 12%; p0.001) compared to non-Crohn's patients. Patients with ≥30 years of follow-up had similar function as those with 20-30 years of follow-up.This was a retrospective, single-institution study. Only 35% of pouches created during the study period had20 years of follow-up.Most patients maintain reasonably good function and retain their pouches after 20 years. Over time, stool frequency and seepage increase. Older age and Crohn's disease are associated with worse outcomes.

Se incluyeron aquellos con ≥20 años de seguimiento en persona.PRINCIPALES MEDIDAS DE VALORACIÓN:Se analizaron la función, inflamación, tasas de falla del reservorio y estenosis anal.RESULTADOS:Un total de 203 pacientes tuvieron ≥20 años de seguimiento. De ellos, 71 tenían ≥30 años de seguimiento. Los diagnósticos iniciales incluyeron colitis ulcerosa (83%), colitis indeterminada (9%), poliposis adenomatosa familiar (4%) y enfermedad de Crohn (3%). El 21% de las personas con colitis ulcerosa o indeterminada pasaron posteriormente a la enfermedad de Crohn. La frecuencia promedio de las deposiciones diarias fue de 7 (rango intercuartil 6-8), el 38% experimentó filtración, el 31% tuvo estenosis anal, el 47% experimentó pouchitis y el 18% tuvo falla del reservorio. Con el tiempo, la frecuencia de las deposiciones aumentó en el 41% de los pacientes, se mantuvo igual en el 43% y disminuyó en el 16%. Los pacientes mayores de 50 años en el momento de la construcción tenían más evacuaciones intestinales diarias (media 8 vs 6, p = 0,02) y más filtraciones (77% vs 35%, p = 0,005) que los menores de 50 años. Los pacientes con enfermedad de Crohn tenían mayor frecuencia de deposiciones (media 8 vs 6, p0,001) y tasas más altas de estenosis anal (44% vs 26%, p = 0,02), inflamacion (70% vs 40%, p0,001) y falla del reservorio (38% frente a 12%, p0,001) en comparación con pacientes que tenian enfermedad de Crohn. Los pacientes con ≥30 años de seguimiento tuvieron una función similar a aquellos con 20-30 años de seguimiento.LIMITACIONES:Este fue un estudio retrospectivo de una sola institución. Solo el 35% de los reservorios creados durante el período de estudio tuvieron más de 20 años de seguimiento.CONCLUSIONES:La mayoría de los pacientes mantienen una función razonablemente buena y conservan el reservorio después de 20 años. Con el tiempo, la frecuencia de las deposiciones y la filtración aumentan. La vejez y la enfermedad de Crohn se asocian con peores resultados. Consulte Video Resumen en http://links.lww.com/DCR/B801.

Background: The management of high and complex anal fistulas remain a therapeutic challenge as it is often associated with recurrence and anal incontinence. The oldest and theoretically the simplest technique is to use a seton. The aim of this study is to find out the outcome of seton in the treatment of complex fistula in ano. Materials and methods: This cross-sectional study was done in surgical units of ShSMCH and colorectal surgery units of BSMMU from September 2014 to August 2015. Fifty patients with high anal fistula having internal opening above dentate line and with multiple fistulas tract were included by purposive sampling. Patients with low anal fistula, fistula in ano associated with Crohn’s disease, active abdominal tuberculosis, carcinoma of rectum, previous radiation therapy, with recurrent fistula in ano and in whom the internal opening could not be located were excluded. After initial evaluation, the fistula tract and opening were located. The skin and anoderm overlying the fistulous tract were incised. This double-strand seton was then tied over itself on the sphincter without excessive tension. The long end of each suture was tapped to the patient’s medial thigh. Postoperatively warm sitz bath after each bowel movement was advised. The patients were informed in detail about the presence of seton prosthesis and they were warned about the possible serous discharge that would continue until the seton dropped, and the wound healed. Data were recorded on the predesigned questionnaire and analyzed using SPSS version 16. Results: Among 50 cases mean age was 41 years, M: F was 4.5:1. Discharge from perianal sinus, pain, swelling and itching were common clinical presentation. All of the patients were discharged on the third postoperative day. None required readmission or needed narcotic analgesics after discharge. The average time for the seton to cut through the sphincter was 1 to 3 months. 28% had complete healing at 1 month and 66% at 3 months postoperatively. Flatus Incontinence was noted 16% cases followed by recurrence (6%), liquid stool incontinence (4%) and postoperative anal stricture was (2%) of cases. Conclusion: This study found that the seton is a safe and low morbidity option for the treatment of high and complex fistula-in-ano, having higher healing rates, with good quality of life. It can therefore be recommended as the standard treatment for complex fistula-in-ano. J Shaheed Suhrawardy Med Coll, December 2020, Vol.12(1); 15-19

Background Anorectal stricturing is a particularly morbid manifestation of Crohn's disease resulting in a diminished quality of life related to pain, incontinence, and recurrent operative interventions. Objective To determine the role of medical therapy, endoscopic dilation, and surgical intervention for the treatment of isolated anorectal stricturing. Data sources An organized search of MEDLINE, PubMed, EMBASE, Scopus, and the Cochrane Database of Collected Reviews was performed from January 1, 1990 through May 1, 2020. Study selection Full text papers which included management of isolated anorectal strictures in the setting of Crohn's disease. Intervention(s) Medical and surgical management. Main outcome measures Symptomatic relief, need for proctocolectomy. Results Our search identified a total of 553 papers; after exclusion based on title (n = 430) and abstract (n = 47), 76 underwent full text review with 65 relevant to the management of anorectal strictures. A summary of the retrospective reports suggests that medical therapy can help control luminal inflammation, but fibrosis may ultimately set in resulting in a need for endoscopic or surgical intervention. Surgical options are limited in the anal canal due to inflammation and ulceration and concomitant perianal fistulizing disease. While fecal diversion can provide symptomatic relief, successful restoration of intestinal continuity remains uncommon and most patients ultimately undergo a total proctocolectomy with end ileostomy. Limitations Limited literature published, all retrospective in nature. Conclusions Despite significant advances in medical and surgical therapy in Crohn's disease over the last decades, there is clearly an unmet need in the management of anorectal strictures in Crohn's disease.

Background Anorectal malformations (ARMs) are major congenital malformations occurring in female children in approximately 1 out of every 4000–5000 births. Posterior sagittal anorectoplasty (PSARP) was introduced for their treatment in early 1980s by Pena and Devries. However, anterior sagittal anorectoplasty (ASARP) was first introduced by Okada as a modification of the previous technique. Purpose The aim of this study was to report our experience and the long-term follow-up results of 594 female patients with anorectal malformations treated by anterior sagittal anorectoplasty (ASARP) in a single center over 22 years. We chose this approach as the incision is smaller, with minimal cutting of the external sphincter and easier dissection of the vagina and rectum. The type of our study was retrospective study. Results The study included 594 patients; 342 of them were less than 1 year old. About 526 patients had rectovestibular fistula, anterior perineal anus in 55 patients, anocutaneous fistula in 6 patients and rectovaginal fistula in 7 patients. All of these patients had been subjected to ASARP technique which had been done in one stage without proceeding colostomy in about 470 cases and in staged fashion with a protective colostomy in 124 patients. Postoperative follow up revealed that four patients (0.7%) developed anal retraction, 30 patients (5%) developed anal stricture, 20 patients (3.4%) had rectal prolapse and 40 patients (6.7%) developed anterior anal migration. Constipation was observed in 161 patients (27%) by the end of 1st postoperative year reduced to 41 patients (7%) after one year. 474 patients were assessed for continence by Kelly's continence score and 453 patients showed good result, 16 patients showed fair result and about 5 patients had poor continence outcome. Conclusion Anterior sagittal anorectoplasty is a procedure with optimal functional outcome especially at if done at an early age in one stage without preliminary colostomy.

Laparoscopic-assisted anorectoplasty (LAARP) is considered to benefit the patients with vesico-prostatic fistula. The aim of this study is to present the details of our LAARP technique for improving the short- and long-term outcomes in the patients with high and intermediate types of anorectal malformations (ARMs). 330 patients with high-type (174 cases) and intermediate-type (156 cases) anorectal malformation (aged 8 days to 15 years) underwent LAARP from 2001 to 2019. LAARP was performed for full mobilization and resection of the dilated rectum, intra-rectal closure of the fistula, visualization, and enlargement of the center of the longitudinal muscle tube (LMT) from pelvic and perineal aspects. LAARP was performed in all patients and no patient was converted to open procedure. The urethral diverticulum was found in three patients (1.02%, 3/294) according to postoperative protocol voiding cystourethrogram but was not associated with any symptoms such as urinary tract infection and dysuria. Rectal prolapse requiring surgical intervention developed in 25 (7.6%) of 330 patients. Anal stricture occurred in three patients and re-do anoplasty was performed 5 months after LAARP. Anal retraction occurred in two patients and re-pull-through was conducted at 5 and 6 days, respectively, after LAARP. 228 patients who were older than 3 years were followed up. The median follow-up period was 5.8 years (range 3–15 years). 217 patients (95.2%) had voluntary bowel movements; 202 patients (88.6%) were free from soiling or with grade 1 soiling; 30 patients (13.6%) and 25 patients (11.3%) suffered from grade 1 and grade 2 constipation, respectively, while no patient had grade 3 constipation. Our experience demonstrates that the LAARP has advantages on rectal mobilization and resection, intra-rectal fistula closure and accurate tunnel formation in the LMT with minimal trauma. The improvement of the short-term and long-term outcomes after LAARP has been shown not only for high-type ARM but also for intermediate-type ARM.

International audience; BACKGROUND AND AIMS: The natural history of perianal Crohn’s disease (PCD) remains poorly described and is mainly based on retrospective studies from referral centres. The aim of this study was to assess the incidence, outcomes and predictors of the onset of PCD. METHODS: All incident cases of patients diagnosed with possible CD were prospectively registered from 1994 to 1997 in Brittany, a limited area in France. At diagnosis, the clinical features of perianal disease were recorded. All patient charts were reviewed from the diagnosis to the last clinic visit in 2015. RESULTS: Among the 272 out of 331 incident CD patients followed up, 51 (18.7%) patients had PCD at diagnosis. After a mean follow-up of 12.8 years, 93 (34%) patients developed PCD. The cumulative probabilities of perianal CD occurrence were 22%, 29%, and 32% after 1 year, 5 years, and 10 years, respectively. The cumulative probabilities of anal ulceration were 14%, and 19% after 1 year and 10 years, respectively. Extraintestinal manifestations were associated with the occurrence of anal ulceration. The cumulative probabilities of fistulizing PCD were 11%, 16%, and 19% after 1 year, 5 years, and 10 years, respectively. Extraintestinal manifestations, rectal involvement and anal ulceration were predictors of fistulizing PCD. The cumulative probability of developing anal stricture was 4% after 10 years. CONCLUSIONS: PCD is frequently observed during CD, in approximately one-third of patients. These data underline the need for targeted therapeutic research on primary perianal lesions (proctitis, anal ulceration) to avoid the onset of fistulizing perianal disease.

The optimal surgical treatment for anatomical anal stenosis (AS) remains to be determined. The aim of this study was to determine the rates of complications and recurrence after anoplasty for anatomical AS and, wherever feasible, compare the outcomes for the various techniques.A PROSPERO-registered systematic review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Medline, PubMed, Embase, Cochrane Library of Systematic Review, Scopus and Web of Science were searched for articles published up to May 2021. Studies that assessed the outcomes of anoplasty in adult patients with anatomical AS were selected. The primary outcomes were complications and recurrence. The methodological quality of studies was appraised using the Joanna Briggs Institute critical appraisal tools.From the total of 2705 unique screened records, 151 were assessed for eligibility. Only 29 studies (two prospective) met the inclusion criteria, reporting data on 556 patients [mean age 53 (18-83) years, 46% female]. Previous history of surgery for haemorrhoidal disease accounted for three quarters of cases. A total of 14 types of anoplasty were found, with the Y-V flap being the most performed technique [27% of cases (n = 149)]. Complications frequently occurred, with a pooled prevalence of 10.2% (95% CI 3.9%-24.1%) after Y-V flap and 11.5% (5.3%-23.0%) after rhomboid/diamond flap. Patients undergoing house flap achieved better results in terms of clinical improvement, satisfaction and quality of life compared with Y-V flap and rhomboid/diamond flap. When considering only studies with at least 12 months of follow-up, the pooled prevalence of recurrence was 4.7% (2.2%-9.8%), with significantly higher rates observed in the prospective versus retrospective series [pooled prevalence 18.9% (11.5%-29.5%) vs. 3.6% (1.7-7.8%), respectively; p 0.001].Both complications and recurrence were significantly lower after house flap compared with rhomboid/diamond and Y-V flap. Better designed multicentre studies with longer follow-up are needed to confirm these findings.CRD42021239493.

OBJECTIVE Endoscopic submucosal dissection (ESD) for laterally spreading tumors (LST) involving the dentate line (LST-DL) is challenging because of the specific anatomical features of the anorectum. This study aimed to evaluate the efficacy and safety of ESD for LST-DL. METHODS Consecutive patients with LST-DL who had undergone ESD at our hospital between January 2010 and December 2015 were retrospectively enrolled in this study. Rates of en bloc resection, R0 resection, and complications, pathological characteristics, and tumor recurrence were analyzed and compared with those of LST in the rectum not involving the dentate line (LST-NDL). RESULTS Altogether 49 patients with LST-DL (median age 63 years; 39 women; median lesion size 57 mm; median follow-up period of 24 months) and 96 patients with LST-NDL (median age 67 years; 31 women; median lesion size 47 mm; median follow-up period of 31 months) were enrolled. En bloc resection (93.9% [46/49] vs 94.8% [91/96]) and en bloc R0 resection rates (83.7% [41/49] vs 88.5% [85/96]), respectively, for LST-DL and LST-NDL, with no significant differences. However, ESD for LST-DL had a longer procedure time (77 min vs 54 min, P = 0.02), a greater postprocedural perianal pain rate (28.6% vs 0%, P

Introduction Acquired skin-level strictures following posterior sagittal anorectoplasty (PSARP) and some rare cases of congenital anal stenosis can be managed using a Heineke–Mikulicz like anoplasty (HMA). We hypothesized that this procedure was an effective, safe, and durable outpatient procedure in select patients. Methods We retrospectively reviewed all patients who underwent HMA for skin level strictures following PSARP or for certain congenital anal stenoses from 2014 to 2017. Results Twenty-eight patients (19 males, 9 females) with a mean age of 5.8 years (range 0.5–24.4) underwent HMA. Twenty-six had a prior PSARP, of which 18 were redo, and 8 were primary procedures. Two patients had congenital skin level anal stenosis. The mean follow up was 1.0 years (range 0.4–2.9). The average preprocedure anal size was Hegar 8, which after HMA increased 8 Hegar sizes to 16 (95% CI 7–9, p Conclusion HMA is a safe procedure for skin-level anal strictures following PSARP (primary and redo) and can also be used in some rare cases of congenital anal stenosis. Long-term follow up to determine the restricture rate is ongoing. A plan to do an HMA if a stricture develops may offer an alternative to routine anal dilations, particularly after a redo PSARP in an older child. Type of study Case series. Level of evidence Level IV.

Background: Perianal fistulizing Crohn’s disease (pCD) has a significant impact on patients’ health and quality of life. Current treatment options have a relatively low success rate and a high recurrence risk. Positive effects of hyperbaric oxygen (HBO2) therapy have been indicated in animal studies as well as in small case series. Methods/Design: This is a non-randomized, controlled pilot study. A total of 20 patients with pCD who have been refractory to standard therapy for at least six months will be included. Patients with a seton and stable treatment regimen will be included. Patients with anal strictures, rectovaginal fistulas, stoma or deep ulceration of the rectum will be excluded. Patients who are eligible but refuse HBO2 will be asked to serve as controls. Patients in the HBO2 group will be treated with 40 sessions of HBO2 therapy at 243-253 kPa, with the seton being removed after 30 sessions. Co-primary endpoints are changes in the perianal disease activity index and MRI-scores. Secondary outcomes are fistula drainage assessment, laboratory findings and patient-reported outcomes. Assessment will be done at baseline, 16 weeks, 34 weeks and 60 weeks after finishing HBO2. Discussion: The aim of this study is to investigate the feasibility and therapeutic effect of HBO2 on pCD. The oneyear follow-up should provide information on the effect durability. A comparison between patients treated with HBO2 and patients who continue to receive standard care will be made. The risk of bias will be limited by using clearly defined inclusion and exclusion criteria, baseline characteristics and consecutive recruitment of patients through an outpatient fistula clinic. Trial registration: The HOT-TOPIC trial has been approved by the local Medical Ethical Committee of the Academic Medical Centre in Amsterdam, the Netherlands. The trial has been registered at the Netherlands Trial Register (www.trialregister.nl), registration number: NTR 6676. Protocol version: August 2017, version 3.0.

Background KBG syndrome is a rare autosomal dominant genetic condition(Morel Swols et al., 2017) characterized mainly by skeletal abnormalities, distinctive facial features, and intellectual disability(Anon, n.d.) with a total of 150 reported cases(Anon, n.d.) in literature. Affected members in family show variable penetration(Kumar et al., 2009; Herrmann et al., 1975). Coeliac disease (gluten sensitive enteropathy) is an autoimmune condition that primarily affects the small intestine and occurs in people at any age who become sensitive to a protein called gluten in their diet(Burden et al., 2014, Anon, n.d.). This is the first reported case of KBG syndrome complicated with recurrent urinary tract infections(UTI), vesicoureteral reflux(VUR), anal stricture, recurrent intussusception and Coeliac disease. Objectives To show the association of autoimmune disease and intussusception with KBG syndrome. Methods A 16-year-old girl, diagnosed with KBG syndrome presented with recurrent abdominal pain, loose watery stools and loss of appetite for 1 year. She presented to the hospital with recurrent UTI due to VUR from the age of 3 weeks up to date and had suffered from difficulties in passing stools from birth. However, an anal stricture was diagnosed and an ileostomy was performed at the age of 5 years. The genetic diagnosis of KBG syndrome was confirmed at the age of 10 years. Percutaneous endoscopic gastrostomy (PEG) was performed to manage feeding difficulties at the age of 12 years and she had a history of several spontaneously resolving intussusception episodes since last year. Intellectual disability, behavioral problems and developmental delay specially speech have been part of this problem(Morel Swols et al., 2017). Her clinical examination in the recent admission was unremarkable except for pallor and right sided abdominal tenderness. The baseline investigations showed iron deficiency anemia and other causes for failure to thrive were ruled out. In addition to radiological diagnosis(by MRI) of intussusception, the second line investigations for abdominal pain and loose stools showed positive for anti-TTG antibody and which was later confirmed by genetic tests (HLA-DQ2 + HLA-DQ8) for coeliac disease. Results Following the gluten free diet, her abdominal symptoms has shown improvement. Conclusions KBG syndrome was diagnosed at a later stage in this patient due to the rareness of the condition. This patient has been suffering from the most of the complications of the disease out of which developmental delay and personality changes, led to delayed diagnosis of the abdominal pathology. The further evaluations with endoscopy procedures has been planned. Associated risk of autoimmune diseases and intussusception with KBG syndrome is yet to be identified.

Background Crohn's disease is a relative contraindication to IPAA due to perceived increased rates of pouch failure. Objective This study aimed to determine pouch functional outcomes and failure rates in patients with a known preoperative diagnosis of Crohn's disease. Data sources A database search was performed in Ovid Medline In-Process & Other NonIndexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid Cochrane Central Register of Controlled Trials, and Ovid Cochrane Database of Systematic Reviews. Study selection The published human studies that reported short-term postoperative outcomes and/or long-term outcomes following IPAA in adult (≥18 years of age) Crohn's disease populations were selected. Intervention Ileal pouch anal anastomoses were constructed in patients who had Crohn's disease diagnosed preoperatively or through proctocolectomy pathology. Main outcomes measures The primary outcomes measured were long-term functional outcomes (to maximal date of follow-up) and the pouch failure rate. Results Of 7019 records reviewed, 6 full articles were included in the analysis. Rates of pelvic sepsis, small-bowel obstruction, pouchitis, anal stricture, and chronic sinus tract were 13%, 3%, 31%, 18%, and 28%. Rates of incontinence, urgency, pad usage in the day, pad usage at night, and need for antidiarrheals were 24%, 21%, 19%, 20%, and 28%, and mean 24-hour stool frequency was 6.3 bowel movements at a mean 69 months of follow-up. The overall pouch failure rate was 15%; no risk factors for pouch failure were identified. Limitations This investigation was limited by the small number of studies with significant study heterogeneity. Conclusion In patients with known preoperative Crohn's disease, IPAA construction is feasible with functional outcomes equivalent to patients with ulcerative colitis, but, even in highly selected patients with Crohn's disease, pouch failure rates remain higher than in patients with ulcerative colitis.

Anal pain is a potentially highly debilitating symptom. It is frequently considered as an idiopathic problem but in some cases it could be due to nonfunctional or organic diseases. The manuscript analyzes the most common causes of nonfunctional and functional chronic anal pain, highlighting false beliefs and functional implications. Hemorrhoids rarely are painful unless they became complicated and develop thrombosis or necrosis. Instead, hemorrhoidectomy could develop easily persistent anal pain. The most common cause of anal pain is anal fissure. Also cryptoglandular anal abscess or anal stricture can lead to pain. Chronic anal pain is usually connected with an important anal resting and involuntary hypertonia and leads to a difficult evacuation. Other causes of chronic nonfunctional anal pain are considered and discussed.

Introduction Short-term international medical service trips (MSTs) provide specialized care in resource-constrained countries. There are limited data on immediate and long-term reported outcomes following specialty MST. We hypothesized that dedicated collaborative MST team and host institution produce outcomes and results comparable to those of high-income settings. Our primary aim was to analyze the long-term surgical and functional outcomes of our specialty-specific MSTs following five years of annual MST in Honduras. Methods We performed a single-institution retrospective analysis of 56 children who underwent colorectal and pelvic reconstructive operations between 2014 and 2018. Demographics, diagnosis, comorbidities, type of repair, long-term complications, and functional bowel and bladder results were recorded. Results We included a total of 56 children, 47 with ARM and 9 with HD, with a median age of 43.5 months (17–355) at the time of surgery. 25% (22) of the patients were lost to follow-up. Fecal continence was achieved by 23 (60%) patients 5 years (n = 11). Complications included constipation in 18 (42.9%) children with ARM and in 1 (12.5%) with HD. Eleven (19.6%) patients required revisional surgery for skin level anal stricture. Seventy-five percent of the patients with pediatric colorectal disorders attending the MST were compliant with continued long-term follow-up. Conclusion We were able to demonstrate that with organized, dedicated site and surgeon, results achieved can be comparable to those in the high-income countries (HICs). We conclude that this type of specialized care is feasible and beneficial for affected pediatric colorectal patients in resource-limited settings, when a strong partnership with a system of preoperative assessments and peri- and postoperative care can be established. Level of evidence Level IV (retrospective cohort study).

The treatment of anal stenosis and anal fissure in patients with anorectal Crohn’s disease requires knowledge of medical management, their natural history, and familiarity with the outcomes of various management modalities. The preservation of continence and functional outcome must be balanced with the potential for poor healing. Anal stricture dilation offers the best initial treatment for symptomatic anal stricture from Crohn’s disease. Operative approaches to anal stricture, including stricture division and sphincteroplasty, have resulted in improvement. Lateral internal sphincterotomy has resulted in the healing of anal fissure in patients with known anorectal Crohn’s disease.

Foreign body ingestion is not uncommon in pediatric age group. Foreign bodies including coin retention/impaction at the colorectal regions are less frequently reported in children and extremely rare in the operated cases of anorectal malformation (ARM). The present case is a 5.8-year-old boy who had retention of ingested foreign body (coin) in his rectum for 4 months. His history revealed that he was a case of high ARM which was managed with three-staged procedures. His clinical examination and radiological investigations revealed an anal stricture and a foreign body (coin) in his rectum. He was managed well with anal dilatation and removal of coin under general anesthesia. The intention for presenting the case is its rarity.

INTRODUCTION: Intestinal complications in inflammatory bowel disease indicate active inflammation and typically result in the intensification of therapy. AIM: To analyse whether the rates of intestinal complications were associated with age at disease onset. PATIENTS AND METHODS: Data from 1506 individuals with Crohn's disease (CD) and 1201 individuals with ulcerative colitis (UC) were obtained from the Swiss inflammatory bowel disease cohort study database, classified into groups on the basis of age at diagnosis ( 40 years of age), and retrospectively analysed. RESULTS: In CD patients, the rates of stricturing (29.1-36.2%), abdominal penetrating disease (11.9-18.2%), resectional surgery (17.9-29.8%) and perianal disease (14.7-34.0%) were correlated with disease duration, but not age at diagnosis. However, paediatric-onset CD was associated with higher rates of multiple, rectal and anal strictures and earlier colon surgery. In addition, perianal disease occurred earlier, required earlier surgical intervention, and was more often combined with stricturing and penetrating disease. Finally, anal fissures were more prevalent among younger patients. In UC patients, the rates of progression or extension of disease (0-25.8%) and colectomy (3.0-8.7%) were dependent on disease duration, but not age at disease onset. Paediatric-onset disease was associated with a higher rate of extensive colitis at diagnosis and earlier progression or extension of disease, and nonsurgically treated patients with the youngest ages at onset more frequently required antitumour necrosis factor-α treatments. CONCLUSION: The higher rates of intestinal complications, including those of the small and large bowel and in the anal region, in paediatric-onset CD patients point towards a level of inflammation that is more difficult to control. Similar findings were also evident in UC patients.

For decades, paediatric surgeons have employed the standard posterior sagittal anorectoplasty (PSARP) approach to deal with patients with anorectal malformations (ARM). In recent years, we noted an apparent increase in the incidence of anal stricture after surgical repair of ARM following the introduction of laparoscopic pull-through and techniques aiming to preserve the internal sphincter—the internal sphincter sparing approach (ISSA). We decided to analyse our data to find out if these new trends had added to the problem of post-operative strictures. All patients with ARM at our institution from January 2000 to December 2015 were identified. A retrospective case note review was carried out. Data collected included patient demographics, type of ARM, operative details, and post-operative outcomes. 114 patients were identified. Ten patients were excluded. Of the remaining 104 children, 48 (46%) were female. Median age was 8.3 (range 1.2–16.8) years. Types of ARM were as follows: perineal fistula (15 patients), anterior stenotic anus (12), imperforate anus without fistula (10), vestibular fistula (32), rectourethral (bulbar) fistula (11), rectourethral (prostatic) fistula (14), rectovesical fistula (7), and cloaca (3). Twenty-seven patients with a perineal fistula or anterior stenotic anus underwent perineal procedures that were variably described by the different operating surgeons. The majority (15 patients) had an anoplasty, 5 had anal transposition, 5 had limited PSARP, and 2 patients had ISSA. Two patients with a cloacal anomaly underwent open cloacal reconstruction. Of the remaining 75 patients, 45 had a PSARP approach, 6 had a laparoscopic-assisted pull-through, and 18 had ISSA. Four girls with vestibular fistula had anal transposition and two boys with imperforate anus without fistula had anoplasty. 15 (14%) children developed anal stricture. Stricture incidence differed according to operation type. PSARP was the most commonly performed procedure, with only 6% developing a stricture. In contrast, 30% of ISSA patients and 50% of children who had laparoscopic pull-through developed a stricture. Strictures also occurred in 11 and 12% of children having anal transposition and anoplasty, respectively. The laparoscopic-assisted pull-through involves tunnelling the sphincter muscle complex. We found that often the tunnels were not wide enough, resulting in narrowing not just at the ano-cutaneous junction but also at the deeper level. 50% developed strictures. We have modified our technique by ensuring that the tunnels are generous enough to allow the rectum to be pulled through without any resistance. ISSA unfortunately resulted in 30% of our patients developing strictures. This approach, started in 2004, was, therefore, abandoned in 2013. The standard Pena’s PSARP, with or without a laparotomy, has stood the test of time. Any modification of this approach must be carefully thought through and audited meticulously. Strictures can cause significant morbidity, which may need several revisions, and the resulting redo anoplasties run the risk of sphincter damage, ironically which the newer modifications of ISSA were trying to conserve.

Introduction Attempting to decrease iatrogenic injuries and preventable harm, safety initiatives have become a priority in surgery. For adult hepatobiliary surgery, it has become common to study and consider “error traps” or common pitfalls that exist for laparoscopic cholecystectomy. 1 , 2 , 3 , 4 Extending this work to children, we have attempted to apply some of these initiatives by identifying error traps common to the care of patients born with anorectal malformations (ARM). Methods Five error traps were identified based on a retrospective analysis of operative records and radiographic studies from 398 re operative ARM cases performed by the authors. Once identified, the authors constructed a specific safety plan for each trap to promote a culture that will hopefully prevent ARM iatrogenic injuries. Results The identified error traps are: 1) creation of a colostomy too distal in the sigmoid colon, 2) inaccurate distal colostogram and definition of the patient's preoperative anatomy 3) absence of a Foley catheter during the repair of an ARM in males and the hazards of separating the anterior rectal wall from the genito-urinary (GU) tract 4) mismanagement of a post-operative anal stricture following an ARM reconstructive procedure 5) limited or unstructured follow up of these patients. For each of the five traps the authors present suggestions for their avoidance. Conclusion The repair on an anorectal malformation is an elective procedure and while not completely avoidable, there should be little tolerance for iatrogenic injury and preventable harm. A culture of safety should be followed, beginning with a recognition of the common error traps associated with ARM procedures.

Although postoperative strictures after endoscopic submucosal dissection (ESD) in the rectum are relatively rare, some rectal lesions require resection involving the anal canal, which is a narrow tract comprising squamous epithelium. To the best of our knowledge, no studies have investigated narrow anal canals when evaluating post-ESD strictures. This study aimed to evaluate the impact of resections involving the anal canal on postoperative stricture development. Between April 2005 and October 2017, 707 rectal lesions were treated with ESD. We retrospectively investigated 102 lesions that required ≥ 75% circumferential resection. Risk factors for post-ESD stricture and, among patients with strictures, obstructive symptoms, and number of dilation therapies required were investigated. Post-ESD stricture occurred in 18 of 102 patients (17.6%). In the multivariate analysis, circumferential resection ≥ 90% and ESD involving the anal canal (ESD-IAC) were risk factors for postoperative strictures (P ≤ 0.0001 and 0.0115, respectively). Among the patients with strictures, obstructive symptoms were significantly related to anal strictures compared to rectal strictures (100% vs. 27.2%, P = 0.0041). Furthermore, the number of dilation therapies required was significantly greater among patients with anal strictures compared to those with rectal strictures (6.5 times vs. 2.7 times, P = 0.0263). Not only circumferential resection ≥ 90% but also ESD-IAC was a significant risk factor for the stricture after rectal ESD. Furthermore, anal strictures were associated with a significantly higher frequency of obstructive symptoms and larger number of required dilation therapies than were rectal strictures.

Highlights • The occurrence of rectal annular constriction due to infiltration by bladder cancer is relatively rare, and difficult diagnosis by colonoscopy. • The images including computed tomography, colonoscopy, and magnetic resonance imaging was fully recorded in our report. • The poor prognosis was noted from literature review with no record for survival >2 years after diagnosis of a rectal lesion., Introduction Bladder urothelial carcinoma rarely spreads to the gastrointestinal tract, and its presentation in the rectum varies. We report a case of a patient who presented with an annular constriction of the rectum. Presentation of case A 60-year-old man was referred to our hospital with chief complaints of anal stricture and partial obstruction for about 1 month. Computed tomography and magnetic resonance imaging revealed diffuse wall thickening of the rectum, possible high cellularity in the lower portion of urinary bladder, and lesions in the visible pelvic bony structure. A colonoscopy showed a contiguous annular constriction from 5 to 15 cm above the anal verge. Carcinoembryonic antigen and carbohydrate antigen 19-9 levels were 39.75 ng/mL and 139.2 U/mL, respectively. A transurethral bladder biopsy revealed high-grade urothelial cell carcinoma, and anal biopsy showed a poorly differentiated carcinoma arranged in a small nested pattern within the subepithelial area of the anorectal tissue. A colostomy was performed, and the patient was transferred to another hospital for further treatment after series of survey with lung metastasis. Discussion Invasive bladder cancers rarely infiltrates into the rectum and is known with the difficulty diagnosis by colonoscopy. Furthermore, the secondary rectum tumor due to bladder cancer had poor record for survival in the literature review. Conclusion This case of bladder urothelial carcinoma penetrating to the rectum was interesting because it mimicked proctitis with diffuse annular swelling observed in the colonoscopy.

PurposeRadiofrequency ablation (RFA) effectively treats esophageal high-grade dysplasia, but its efficacy in treating anal canal high-grade squamous intraepithelial lesions (HSILs) is unsubstantiated. This prospective study assessed the safety and efficacy of applying hemi-circumferential RFA to anal canal HSIL.MethodsTwenty-one HIV-negative participants with HSIL occupying ≤half the anal canal circumference were treated with hemi-circumferential anal canal RFA. Participants were assessed every 3months for 12months with high-resolution anoscopy; recurrence in the treatment zone was re-treated with focal RFA.ResultsTwenty-one participants with a mean of 1.7 lesions (range 1-4) enrolled and completed the trial. Six (29%) participants had recurrent HSIL within the treated hemi-circumference within 1year. Four participants (19%) had persistence of an index lesion at 3months. One (2.9%) index HSIL persisted again at 12months. No participants had more than two RFA treatments. KM curve-predicted HSIL-free survival within the treatment zone at 1year was 76% (95% CI 52-89%). Comparing the first 7 and last 14 participants, the predicted 1-year HSIL-free survivals are 43% (95% CI 10-73%) and 93% (95% CI 59-99%), respectively (p=0.008), suggesting a learning curve with the treating physician. Multivariable analysis showed decreased recurrence in the last 14 participants (HR 0.02; 95% CI 0.001-0.63) while increasing BMI increased recurrence (HR 1.43, 95% CI 1.01-2.01). No participants had device or procedure-related serious adverse events, anal stricture, or heavy bleeding.ConclusionsHemi-circumferential RFA yielded a high rate of anal HSIL eradication in HIV-negative patients at 1year with minimal adverse events. Lesion persistence was probably related to incomplete initial ablation.
