Abstract
AbstractMalignant neoplasms are increasingly prevalent in the daily clinical practice. Up to 61% of patients with pelvic malignancies undergo pelvic radiotherapy in different doses, which may cause intestinal damage, and the rectum is the segment most frequently affected due to its fixed position in the pelvis. Currently, there are several strategies to minimize the effects of radiation on the tissues surrounding the neoplastic site; despite those strategies, radiotherapy can still result in serious damage to organs and structures, and these injuries accompany patients throughout their lives. One of the most common damages resulting from pelvic radiotherapy is acute proctitis.The diagnosis is confirmed by visualizing the rectal mucosa through rigid or flexible rectosigmoidoscopy and colonoscopy. The objective of the present study was to review the forms of radiation-induced proctopathytherapy, and to evaluate the results of each method to propose a standardization for the treatment of this pathology. Despite the prevalence of radiation-induced proctopathy, there is no definitive standardized treatment strategy so far. The first approach can be tried with local agents, such as mesalazine and formalin. For refractory cases, control can usually be achieved with argon plasma coagulation, hyperbaric oxygen, and radiofrequency ablation therapies. Regarding the study of radiation-induced proctopathy, there is a lack of robust studies with large samples and standardized therapies to be compared. There is a lack of double-blinded, randomized controlled studies to determine a definitive standard treatment algorithm.

Abstract
BACKGROUND AND PURPOSE Significant improvements in the treatment of anal cancer have produced a growing population of anal cancer survivors. These patients often experience late adverse effects related to their treatment. Research has revealed substantial unmet needs because of long-term symptoms and functional impairments after treatment that may negatively affect health-related quality of life. The purpose of the present guidelines is to review the scientific evidence for the management of late adverse effects after (chemo)radiotherapy ([C]RT) for anal cancer and to extrapolate knowledge from other pelvic malignancies treated with pelvic (C)RT so that they may guide the clinical management of late adverse effects. MATERIALS AND METHODS Relevant studies were systematically searched in four databases from their inception to June 2020 (no language limitation) and guidelines were searched in 16 databases, focussing on bowel dysfunction, psychosocial aspects, pain, and sexual and urinary dysfunction. The guidelines were developed by a panel of experts using the Oxford Centre for Evidence-based Medicine, levels of evidence, and grades of recommendations. SCIENTIFIC EVIDENCE Late adverse effects after (C)RT for anal cancer are associated with a low overall quality of life among survivors. The most pronounced late adverse effects are bowel dysfunction (present in up to 78%), urinary dysfunction (present in up to 45%), and sexual dysfunction (present in up to 90% of men and up to 100% of women). Only indirect data on adequate treatment options of these late adverse effects for anal cancer are available. CONCLUSION Quality of life and late adverse effects should be monitored systematically following treatment for anal cancer to identify patients who require further specialist evaluation or support. Increased awareness of the extent of the problem may serve to stimulate and facilitate multidisciplinary collaboration, which is often required.

Diverting colostomy is an effective and reversible option for severe hemorrhagic radiation proctopathy. World J Gastroenterol 2020; 26:850-864. [PMID: 32148382 PMCID: PMC7052535 DOI: 10.3748/wjg.v26.i8.850] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 12/04/2019] [Accepted: 02/14/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Severe chronic radiation proctopathy (CRP) is difficult to treat.
AIM To evaluate the efficacy of colostomy and stoma reversal for CRP.
METHODS To assess the efficacy of colostomy in CRP, patients with severe hemorrhagic CRP who underwent colostomy or conservative treatment were enrolled. Patients with tumor recurrence, rectal-vaginal fistula or other types of rectal fistulas, or who were lost to follow-up were excluded. Rectal bleeding, hemoglobin (Hb), endoscopic features, endo-ultrasound, rectal manometry, and magnetic resonance imaging findings were recorded. Quality of life before stoma and after closure reversal was scored with questionnaires. Anorectal functions were assessed using the CRP symptom scale, which contains the following items: Watery stool, urgency, perianal pain, tenesmus, rectal bleeding, and fecal/gas incontinence.
RESULTS A total of 738 continual CRP patients were screened. After exclusion, 14 patients in the colostomy group and 25 in the conservative group were included in the final analysis. Preoperative Hb was only 63 g/L ± 17.8 g/L in the colostomy group compared to 88.2 g/L ± 19.3 g/L (P < 0.001) in the conservative group. All 14 patients in the former group achieved complete remission of bleeding, and the colostomy was successfully reversed in 13 of 14 (93%), excepting one very old patient. The median duration of stoma was 16 (range: 9-53) mo. The Hb level increased gradually from 75 g/L at 3 mo, 99 g/L at 6 mo, and 107 g/L at 9 mo to 111 g/L at 1 year and 117 g/L at 2 years after the stoma, but no bleeding cessation or significant increase in Hb levels was observed in the conservative group. Endoscopic telangiectasia and bleeding were greatly improved. Endo-ultrasound showed decreased vascularity, and magnetic resonance imaging revealed an increasing presarcal space and thickened rectal wall. Anorectal functions and quality of life were significantly improved after stoma reversal, when compared to those before stoma creation.
CONCLUSION Diverting colostomy is a very effective method in the remission of refractory hemorrhagic CRP. Stoma can be reversed, and anorectal functions can be recovered after reversal.

Abstract
BACKGROUND Management of radiation proctitis presents a treatment challenge. Limited data exist on the management of symptomatic hemorrhoids in radiated patients. This study aims to present a practical approach to the management of radiation proctitis, particularly in patients with synchronous hemorrhoids. METHODS A total of 52 consecutive cases of radiation proctitis managed between September 1999 and October 2017 were retrospectively reviewed. The primary treatment was formalin application, plus rubber band ligation in conjunction with formalin when hemorrhoids were a significant component of bleeding, and occasionally argon plasma coagulation. RESULTS The primary indication for radiotherapy was for the treatment of prostate cancer (71%), anal squamous cell carcinoma (10%), and gynecological malignancies (18%). More than half of the patients (52%) presented with radiation proctitis and concomitant internal hemorrhoids. The hemorrhoids were managed with rubber band ligation (56%) and stapled hemorrhoidectomy (7%), at the same procedure as formalin application. At a median follow-up of 12 months, no recurrent rectal bleeding occurred, and no further treatment was needed for most patients. One patient experienced a short period of perianal pain, which was treated with analgesics. CONCLUSION Formalin application has consistently demonstrated an excellent cure rate and safety profile comparable with the published results as a primary treatment for radiation proctitis. The prolapse of irradiated mucosa over the internal hemorrhoids appears to exacerbate bleeding. Local hemorrhoid treatment is often required as an adjunct in the management of these patients.

Abstract
BACKGROUND External hemorrhoidal thrombosis is a common disease with an acute anal pain as the major symptom. It is astonishing the lack of studies which investigates the most effective treatment and there are not guidelines. Furthermore, nobody has ever evaluated this peculiar condition in an elderly population. METHODS We have considered 87 patients aged >75 years who were visited and treated for this condition in our clinic, dividing them in three groups according the curative option chosen together with them after anamnesis and an interview: a conservative medical treatment (Group A), an immediate incision and evacuation of the thrombus (Group B) and the excision of hemorrhoid with the thrombus, with hemorrhoidectomy technique (Group C). The mean follow-up was 12.3 months. We analyzed immediate pain relief and time of remission of symptoms, bleeding, recurrences and major complications. RESULTS The Group A presented a remission of symptoms in 11.8 days, Group B in 1.58 ad Group C in 7.8 days. The recurrence rate was very similar for the first two options (19.4% and 16.1%) and lower in the excision group (no recurrence during follow-up). Bleeding is the common adverse event observed with a high frequency in the immediate incision and evacuation of thrombus, less common in hemorrhoidectomy, that did not present major complication. Surgical option is often refused by elderly patient evaluating comorbidities in the fear of adverse events. CONCLUSIONS The surgical treatment for EHT in elderly is safe and effective, but not the most common choice for fear of complications. Medical treatment or immediate incision of thrombus can be preferred and well accepted by elderly even if followed by a higher rate of recurrences.

Abstract
CONTEXT Radiotherapy used for treating localized prostate cancer is effective at prolonging cancer-specific and overall survival. Still, acute and late pelvic toxicities are a concern, with gastrointestinal (GI) and genitourinary (GU) sequelae being most common as well as other pelvic complications. OBJECTIVE To present a critical review of the literature regarding the incidence and risk factors of pelvic toxicity following primary radiotherapy for prostate cancer and to provide a narrative review regarding its management. EVIDENCE ACQUISITION A collaborative narrative review of the literature from 2010 to present was conducted. EVIDENCE SYNTHESIS Regardless of the modality used, the incidence of acute high-grade pelvic toxicity is low following conventionally fractionated external beam radiotherapy (EBRT). After moderate hypofractionation, the crude cumulative incidences for late grade 3 or higher (G3+) GI and GU complications are as high as 6% and 7%, respectively. After extreme hypofractionation, the 5-yr incidences of G2+ GU and GI toxicities are 3-9% and 0-4%, respectively. Following brachytherapy monotherapy, crude rates of late G3+ GU toxicity range from 6% to 8%, while late GI toxicity is rare. With combination therapy (EBRT and brachytherapy), the cumulative incidence of late GU toxicity is high, between 18% and 31%; however, the prevalence is lower at 4-14%. Whole pelvic radiotherapy remains a controversial treatment option as there is increased G3+ GI toxicity compared with prostate-only treatment, with no overall survival benefit. Proton beam therapy appears to have similar toxicity to photon therapies currently in use. With respect to specific complications, urinary obstruction and urethral stricture are the most common severe urinary toxicities. Rectal and urinary bleeding can be recurrent long-term toxicities. The risk of hip fracture is also increased following prostate radiotherapy. The literature is mixed on the risk of in-field secondary pelvic malignancies following prostate radiotherapy. Urinary and GI fistulas are rare complications. Management of these toxicities may require invasive treatment and reconstructive surgery for refractory and severe symptoms. CONCLUSIONS There has been progress in the delivery of radiotherapy, enabling the administration of higher doses with minimal tradeoff in terms of slightly increased or equal toxicity. There is a need to focus future improvements in radiotherapy on sparing critical structures to reduce GU and GI morbidities. While complications such as fistulae, bone toxicity, and secondary malignancy are rare, there is a need for higher-quality studies assessing these outcomes and their management. PATIENT SUMMARY In this report, we review the literature regarding pelvic complications following modern primary prostate cancer radiotherapy and their management. Modern radiotherapy technologies have enabled the administration of higher doses with minimal increases in toxicity. Overall, high-grade long-term toxicity following prostate radiotherapy is uncommon. Management of late high-grade pelvic toxicities can be challenging, with patients often requiring invasive therapies for refractory cases.

Abstract
INTRODUCTION There is a paucity of data on incidence and mechanisms of long-term gastrointestinal consequences after chemoradiotherapy for anal cancer. Most of the adverse effects reported were based on traditional external beam radiotherapy whilst only short-term follow-ups have been available for intensity-modulated radiotherapy, and there is lack of knowledge about consequences of dose-escalation radiotherapy. METHOD A systematic literature review. RESULTS Two thousand nine hundred and eighty-five titles (excluding duplicates) were identified through the search; 130 articles were included in this review. The overall incidence of late gastrointestinal toxicity was reported to be 7-64.5%, with Grade 3 and above (classified as severe) up to 33.3%. The most commonly reported late toxicities were fecal incontinence (up to 44%), diarrhea (up to 26.7%), and ulceration (up to 22.6%). Diarrhea, fecal incontinence and buttock pain were associated with lower scores in radiotherapy specific quality of life scales (QLQ-CR29, QLQ-C30, and QLQ-CR38) compared to healthy controls. Intensity-modulated radiation therapy appears to reduce late toxicity. CONCLUSION Late gastrointestinal toxicities are common with severe toxicity seen in one-third of the patients. These symptoms significantly impact on patients' quality of life. Prospective studies with control groups are needed to elucidate long-term toxicity.

Abstract
AIM Anal fistula is a common disease originated from abscess according the cryptoglandular theory. A rare etiology is the pilonidal disease. In our case we observed a pilonidal disease mimicking an anterior perianal fistula, associated with another posterior anal fistula. CASE PRESENTATION A 36-year old man was referred to our department with an anal fistula with an anterior opening. Despite the clinical examination and the endoanal ultrasound, only during the surgery we discovered the origin of the anterior fistula from a misdiagnosed pilonidal sinus. There was also a posterior anal fistula in communication with the same abscess of the anterior one. We performed a two-step surgery with a first fistulectomy of the anterior tract, a drainage of abscess and the positioning of a seton for the posterior fistula. After about one month and the fall of the seton we evaluate the good healing of posterior anal fistula and excised the residual pilonidal sinus. CONCLUSION This misdiagnosed pilonidal disease created in our clinical report a true challenge. Our goal was to eliminate as much disease as possible, but also to avoid major complications or recurrences. We refused an aggressive approach and chose a two-step surgery, with in the first approach not only a demolitive time but also a reconstruction to facilitate healing, and in the second time the complete eradication of the pathology.

Abstract
PURPOSE The aim of this quasi-experimental study is to evaluate a novel technique for an outpatient application of formalin for chronic rectal bleeding after prostate irradiation. METHODS This is a quasi- experimental clinical trial developed between January 2010 and July 2015, including 35 patients with chronic radiation rectitis (CRP) due to a previous prostate radiation course. The study's eligibility was (1) completed external beam radiation therapy for prostate carcinoma >6 months previously, (2) rectal bleeding, defined as a frequency of >1× per week and/or needing of blood transfusions, and (3) diagnosis of chronic proctitis at colonoscopy. The 5% formalin application was performed by a custom applicator, which requires neither anesthesia nor sigmoidoscopy. The endpoint of the study was bleeding cessation and hemoglobin level. RESULTS The onset of bleeding due to chronic rectitis was 12 months (6-36). During a median follow-up of 24 months, the rate of overall efficacy was 94%. The sustained complete response in 1 and 2 years was 80% and 73%, respectively. The Hb mean pre- and post-treatment differed significantly (12.2 vs 14.4, p = 0.0001). The rates of blood transfusion differed significantly, pre- and post-treatment (17% vs 5.7%, p = 0.031). CONCLUSION The technique is very effective and safe, resulting to a significant improvement of hemoglobin levels and quality of life scores. Further studies are warranted to compare this technique with other treatment options for chronic radiation-induced rectal bleeding.

Abstract
BACKGROUND Perianal fistula is a complex and frequent disease. At present, no treatment nor technique has shown an absolute superiority in terms of efficacy and recurrence rate. The technique has to be chosen considering the balance between faecal continence preservation and disease eradication. Rarely concomitant perianal abscess and fistula are treated at the same time, and often time to complete recovery is long. AIMS The aim of this study was to evaluate the possibility of treating the abscess and the fistula tract in one procedure with total fistulectomy, sphincteroplasty and an almost complete closure of the residual cavity, thus reducing the healing time in older patients. METHODS A non-randomized single-centre series of 86 patients from 2007 to 2012 with low-medium trans-sphincteric perianal fistula (< 30% of external sphincter involvement) with or without synchronous perianal abscess were treated with total fistulectomy, sphincteroplasty and closure of the residual cavity technique. RESULTS Success rate was 97.7% with a healing time of 4 weeks; overall morbidity was 16.2%; recurrence rate was 2.3%; no major alterations of continence were observed. DISCUSSION Fistulectomy, sphincteroplasty and closure of the residual cavity are associated with a low rate of recurrence and good faecal continence preservation in older patients. This technique can be safely used even with a concomitant perianal abscess, with reduction in healing time and in the number of surgical procedures needed. CONCLUSIONS Total fistulectomy with sphincteroplasty and partial closure of the residual cavity, as described, is a safe procedure but has to be performed by dedicated colorectal surgeons.

Abstract
INTRODUCTION Radiation proctitis is radiation induced rectal mucositis, occurring as a consequence to radiation therapy of the pelvic organs for various pelvic region malignancies. The management of radiation proctitis is extremely challenging as no recommended guidelines are available and limited number of studies are there in the literature involving the various treatment options. AIM The aim of the study is the in-depth review of published literature to see the role of various treatment modalities in the management of radiation proctitis. MATERIALS AND METHODS An integrative review was undertaken within PubMed, MEDLINE, PMC, GOOGLE SEARCH databases and articles published upto February 2015 were reviewed and analysed. A total of 54 studies were included. RESULTS Literature suggests that non surgical therapies are the first line of treatment and surgery is reserved for advanced or refractory cases. Endoscopic therapies form the mainstay of treatment in managing the patients of radiation proctitis. Argon plasma coagulation and laser therapies are preferred. Radiofrequency ablation, cryoablation and mesenchymal stem cell therapy are the upcoming modalities. Medical therapy can be tried alone or in conjunction to endoscopic therapies. In the resistant or refractory cases, surgery can be looked for in the form of diversion or resection with or without anastamosis. CONCLUSION Though, a number of options are available, still a lot can be explored in this field to improve the morbidity in the patients and to confirm the superiority of one treatment over other.

Abstract
BACKGROUND This is an update of a Cochrane review first published in 2002, and previously updated in 2007. Late radiation rectal problems (proctopathy) include bleeding, pain, faecal urgency, and incontinence and may develop after pelvic radiotherapy treatment for cancer. OBJECTIVES To assess the effectiveness and safety of non-surgical interventions for managing late radiation proctopathy. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 11, 2015); MEDLINE (Ovid); EMBASE (Ovid); CANCERCD; Science Citation Index; and CINAHL from inception to November 2015. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing non-surgical interventions for the management of late radiation proctopathy in people with cancer who have undergone pelvic radiotherapy for cancer. Primary outcomes considered were: episodes of bowel activity, bleeding, pain, tenesmus, urgency, and sphincter dysfunction. DATA COLLECTION AND ANALYSIS Study selection, 'Risk of bias' assessment, and data extraction were performed in duplicate, and any disagreements were resolved by involving a third review author. MAIN RESULTS We identified 1221 unique references and 16 studies including 993 participants that met our inclusion criteria. One study found through the last update was moved to the 'Studies awaiting classification' section. We did not pool outcomes for a meta-analysis due to variation in study characteristics and endpoints across included studies.Since radiation proctopathy is a condition with various symptoms or combinations of symptoms, the studies were heterogeneous in their intended effect. Some studies investigated treatments targeted at bleeding only (group 1), some investigated treatments targeted at a combination of anorectal symptoms, but not a single treatment (group 2). The third group focused on the treatment of the collection of symptoms referred to as pelvic radiation disease. In order to enable some comparison of this heterogeneous collection of studies, we describe the effects in these three groups separately.Nine studies assessed treatments for rectal bleeding and were unclear or at high risk of bias. The only treatments that made a significant difference on primary outcomes were argon plasma coagulation (APC) followed by oral sucralfate versus APC with placebo (endoscopic score 6 to 9 in favour of APC with placebo, risk ratio (RR) 2.26, 95% confidence interval (CI) 1.12 to 4.55; 1 study, 122 participants, low- to moderate-quality evidence); formalin dab treatment (4%) versus sucralfate steroid retention enema (symptom score after treatment graded by the Radiation Proctopathy System Assessments Scale (RPSAS) and sigmoidoscopic score in favour of formalin (P = 0.001, effect not quantified, 1 study, 102 participants, very low- to low-quality evidence), and colonic irrigation plus ciprofloxacin and metronidazole versus formalin application (4%) (bleeding (P = 0.007, effect not quantified), urgency (P = 0.0004, effect not quantified), and diarrhoea (P = 0.007, effect not quantified) in favour of colonic irrigation (1 study, 50 participants, low-quality evidence).Three studies, of unclear and high risk of bias, assessed treatments targeted at something very localised but not a single pathology. We identified no significant differences on our primary outcomes. We graded all studies as very low-quality evidence due to unclear risk of bias and very serious imprecision.Four studies, of unclear and high risk of bias, assessed treatments targeted at more than one symptom yet confined to the anorectal region. Studies that demonstrated an effect on symptoms included: gastroenterologist-led algorithm-based treatment versus usual care (detailed self help booklet) (significant difference in favour of gastroenterologist-led algorithm-based treatment on change in Inflammatory Bowel Disease Questionnaire-Bowel (IBDQ-B) score at six months, mean difference (MD) 5.47, 95% CI 1.14 to 9.81) and nurse-led algorithm-based treatment versus usual care (significant difference in favour of the nurse-led algorithm-based treatment on change in IBDQ-B score at six months, MD 4.12, 95% CI 0.04 to 8.19) (1 study, 218 participants, low-quality evidence); hyperbaric oxygen therapy (at 2.0 atmospheres absolute) versus placebo (improvement of Subjective, Objective, Management, Analytic - Late Effects of Normal Tissue (SOMA-LENT) score in favour of hyperbaric oxygen therapy (HBOT), P = 0.0019) (1 study, 150 participants, moderate-quality evidence, retinol palmitate versus placebo (improvement in RPSAS in favour of retinol palmitate, P = 0.01) (1 study, 19 participants, low-quality evidence) and integrated Chinese traditional plus Western medicine versus Western medicine (grade 0 to 1 radio-proctopathy after treatment in favour of integrated Chinese traditional medicine, RR 2.55, 95% CI 1.30 to 5.02) (1 study, 58 participants, low-quality evidence).The level of evidence for the majority of outcomes was downgraded using GRADE to low or very low, mainly due to imprecision and study limitations. AUTHORS' CONCLUSIONS Although some interventions for late radiation proctopathy look promising (including rectal sucralfate, metronidazole added to an anti-inflammatory regimen, and hyperbaric oxygen therapy), single small studies provide limited evidence. Furthermore, outcomes important to people with cancer, including quality of life (QoL) and long-term effects, were not well recorded. The episodic and variable nature of late radiation proctopathy requires large multi-centre placebo-controlled trials (RCTs) to establish whether treatments are effective. Future studies should address the possibility of associated injury to other gastro-intestinal, urinary, or sexual organs, known as pelvic radiation disease. The interventions, as well as the outcome parameters, should be broader and include those important to people with cancer, such as QoL evaluations.

Abstract
OBJECTIVE The purpose of this study was to give an overview of the measures used to prevent chronic radiation proctitis (CRP) and to provide an algorithm for the treatment of CRP. METHODS Medical literature databases including PubMed and Medline were screened and critically analyzed for relevance in the scope of our purpose. RESULTS CRP is a relatively frequent late side effect (5-20%) and mainly dependent on the dose and volume of irradiated rectum. Radiation treatment (RT) techniques to prevent CRP are constantly improving thanks to image-guided RT and intensity-modulated RT. Also, newer techniques like protons and new devices such as rectum spacers and balloons have been developed to spare rectal structures. Biopsies do not contribute to diagnosing CRP and should be avoided because of the risk of severe rectal wall damage, such as necrosis and fistulas. There is no consensus on the optimal treatment of CRP. A variety of possibilities is available and includes topical and oral agents, hyperbaric oxygen therapy, and endoscopic interventions. CONCLUSIONS CRP has a natural history of improving over time, even without treatment. This is important to take into account when considering these treatments: first be conservative (topical and oral agents) and be aware that invasive treatments can be very toxic.

Abstract
AIM: To assess the efficacy and safety of a modified topical formalin irrigation method in refractory hemorrhagic chronic radiation proctitis (CRP).
METHODS: Patients with CRP who did not respond to previous medical treatments and presented with grade II-III rectal bleeding according to the Common Terminology Criteria for Adverse Events were enrolled. Patients with anorectal strictures, deep ulcerations, and fistulas were excluded. All patients underwent flexible endoscopic evaluation before treatment. Patient demographics and clinical data, including primary tumor, radiotherapy and previous treatment options, were collected. Patients received topical 4% formalin irrigation in a clasp-knife position under spinal epidural anesthesia in the operating room. Remission of rectal bleeding and related complications were recorded. Defecation, remission of bleeding, and other symptoms were investigated at follow-up. Endoscopic findings in patients with rectovaginal fistulas were analyzed.
RESULTS: Twenty-four patients (19 female, 5 male) with a mean age of 61.5 ± 9.5 years were enrolled. The mean time from the end of radiotherapy to the onset of bleeding was 11.1 ± 9.0 mo (range: 2-24 mo). Six patients (25.0%) were blood transfusion dependent. The median preoperative Vienna Rectoscopy Score (VRS) was 3 points. Nineteen patients (79.2%) received only one course of topical formalin irrigation, and five (20.8%) required a second course. No side effects were observed. One month after treatment, bleeding cessation was complete in five patients and obvious in 14; the effectiveness rate was 79.1% (19/24). For long-term efficacy, 5/16, 1/9 and 0/6 patients complained of persistent bleeding at 1, 2 and 5 years after treatment, respectively. Three rectovaginal fistulas were found at 1 mo, 3 mo and 2 years after treatment. Univariate analysis showed associations of higher endoscopic VRS and ulceration score with risk of developing rectovaginal fistula.
CONCLUSION: Modified formalin irrigation is an effective and safe method for hemorrhagic CRP, but should be performed cautiously in patients with a high endoscopic VRS.

Abstract
BACKGROUND Chronic radiation proctopathy (CRP) is a common sequela occurring even many years after pelvic radiation. Current ablative therapies for bleeding ectatic vessels have the potential for deep tissue injury leading to ulcerations, perforation, and fistulas. Radiofrequency ablation (RFA) therapy avoids deep tissue injury and is a promising treatment for CRP. OBJECTIVE To assess the long-term safety and efficacy of RFA for the treatment of CRP. DESIGN Multicenter, retrospective analysis of a prospectively collected database. SETTING Veterans Affairs Boston Healthcare System, Massachusetts; Sarasota Memorial Hospital and Suncoast Endoscopy of Sarasota, Florida. PATIENTS A total of 39 consecutive patients with CRP. INTERVENTIONS Endoscopic RFA of CRP. MAIN OUTCOME MEASUREMENTS The primary endpoint of the study was complete resolution of rectal bleeding. Secondary endpoints included visually scored improvement of CRP on endoscopic follow-up by using a rectal telangiectasia density (RTD) grading score, improvement in hemoglobin level, and adverse events related to the procedure. RESULTS A total of 39 male patients (mean [± standard deviation {SD}] age 72.9 ± 6.6 years) were included in the study. The mean number of RFA sessions was 1.49 (median 1, interquartile range [IQR] 1-2, range 1-4), with a mean interval of 18 weeks between sessions. Rectal bleeding stopped completely in all patients during the mean follow-up of 28 months (range 7-53 months). A significant improvement occurred in the mean (± SD) hemoglobin level from 11.8 ± 2 to 13.5 ± 1.6 g % (P < .0001). Endoscopic severity also improved significantly with an improvement in the median RTD score from 3 (IQR 2-3) to 0 (IQR 0-1) (P < .0001). Treatment with RFA led to discontinuation of blood transfusion and iron therapy in 92% and 82% patients, respectively. LIMITATIONS Retrospective analysis, lack of control group. CONCLUSION RFA therapy led to complete resolution of rectal bleeding in all treated CRP patients, with improvement in clinical and endoscopic indices without any major adverse events. Further controlled studies are needed to establish RFA as the endoscopic therapy of choice for treatment of CRP.

Abstract
PURPOSE Chronic hemorrhagic radiation proctopathy is not uncommon after radiotherapy for cervical carcinoma. The outcomes of several treatments have been variable. Many studies demonstrate that topical treatment with 4 % formalin is effective and safe. However, a nonrandomized control study showed a high response rate and good tolerance in chronic radiation proctopathy patients treated with 10 % formalin. The optimal concentration of formalin therefore remains unclear. METHODS To compare the effectiveness and safety of 4 and 10 % formalin for the treatment of chronic hemorrhagic radiation proctopathy, a prospective trial was conducted at the Department of Gynecology of the Affiliated Hospital of Binzhou Medical College from January 2009 to December 2012. One hundred and twenty patients with chronic hemorrhagic radiation proctopathy following radiotherapy for cervical carcinoma were recruited and randomized to receive 4 or 10 % formalin. A standard protocol was followed for formalin application. Symptom and rectoscopy scores were evaluated before and at 12 weeks after treatment. RESULTS In the 4 % formalin group, 49 (86.0 %) and 53 (91.4 %) patients showed an improvement in symptom score and rectoscopy score, respectively (P = 0.36). Symptom and rectoscopy scores decreased significantly after treatment in both the 4 % formalin group and the 10 % formalin group (P < 0.001). Symptom score was correlated with rectoscopy score (P < 0.001). More patients in the 10 % group suffered treatment-related complications than did those in the 4 % group (P = 0.03). CONCLUSIONS For the treatment of chronic hemorrhagic radiation proctopathy, 4 % should be the preferred formalin concentration.

Abstract
Chronic radiation proctitis is a complication that occurs in patients who receive radiation therapy for pelvic malignancies. The common presentation is with rectal bleeding, but also rectal pain, diarrhea, tenesmus and even passage of mucus can occur. The optimal treatment of bleeding due to radiation proctitis remains unclear. Among various therapeutic options, medical management is generally ineffective and surgical intervention has a high incidence of morbidity. Promising advances have been made in endoscopic therapy, including argon plasma coagulation (APC), formalin application as well as new techniques such as radiofrequency ablation and cryoablation. APC is a safe, highly effective and long-lasting therapy in patients with rectal bleeding associated with radiation proctitis. It has been shown that several sessions of APC reduce the rate of bleeding and therefore the blood transfusion requirements. Moreover, the effect of treatment is long lasting. However, best results are achieved in patients with mild to moderate radiation proctitis, leaving space for alternative treatments for patients with more severe disease. In patients with severe or refractory radiation proctitis intra rectal formalin application is an appropriate treatment option. Radiofrequency ablation and cryoablation have shown efficacy as alternative methods in a limited number of patients with refractory chronic radiation proctitis.
