Efficacy of surgical treatments for the management of solitary rectal ulcer syndrome: a network meta-analysis.

AIM: Solitary rectal ulcer syndrome (SRUS) is a benign and poorly understood disorder with complex management. Typical symptoms include straining during defaecation, rectal bleeding, tenesmus, mucoid secretion, anal pain and a sense of incomplete evacuation. Diagnosis is based on characteristic clinical symptoms and endoscopic/histological findings. Several treatments have been reported in the literature with variable ulcer healing rates. This study aimed to evaluate the efficacy of different treatments for SRUS. MATERIALS AND METHODS: A systematic review and network meta-analysis were performed according to the PRISMA guidelines. Studies in English, French and Spanish languages were included. Papers written in other languages were excluded. Other exclusion criteria were reviews, case reports or clinical series enrolling less than five patients, study duplications, no clinical data of interest and no article available. A systematic literature search was conducted from January 2000 to March 2024 using the following databases: PubMed/MEDLINE, Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, and Scopus. The biases of the studies were assessed using the Newcastle-Ottawa scale or the Jadad scale when appropriate. Types of treatment and their efficacy for the cure of SRUS were collected and critically assessed. The study's primary outcome was to estimate the rate of patients with ulcer healing. RESULTS: A total of 22 studies with 911 patients (men 361, women 550) diagnosed with SRUS were analysed in the final meta-analysis. The pooled effect estimates of treatment efficacy revealed that surgery showed the highest ulcer healing rate (70.5%; 95% CI 0.57-0.83). Surgery was superior in the cure of ulcers with respect to medical therapies and biofeedback (OR 0.09 and OR 0.14). CONCLUSION: Solitary rectal ulcer syndrome is a challenging clinical entity to manage. Proficient results have been reported with the surgical approach, suggesting its positive role in cases refractory to medical and biofeedback therapy. Further studies in homogeneous populations are required to evaluate the efficacy of surgery in this setting. (PROSPERO registration number CRD42022331422).

Surgical treatment of colorectal endometriosis: an updated review.

PURPOSE OF REVIEW: This review aims to summarize recent literature on the surgical treatment of colorectal endometriosis. RECENT FINDINGS: The last decade has seen a surge in the number of studies on bowel endometriosis, with a focus on preoperative evaluation, perioperative management, surgical approach, and surgical outcomes. Many of these studies have originated from large-volume referral centers with varying surgical approaches and philosophies. Colorectal surgery for endometriosis seems to have a positive impact on patient symptoms, quality of life, and fertility. However, these benefits must be weighed against a significant risk of postoperative complications and the potential for long-term bowel or bladder dysfunction, especially for more radical procedures involving the lower rectum. Importantly, most studies regarding surgical technique and outcomes have been limited by their observational design. SUMMARY: The surgical management of bowel endometriosis is complex and should be approached by a multidisciplinary team. Methodical preoperative evaluation, including appropriate imaging, is vital for surgical planning and patient counseling. The decision to perform a more conservative or radical excision is nuanced and remains an area of controversy. High quality studies in the form of multicenter randomized controlled trials are needed before clear recommendations can be made.

Lesion size and location in deep infiltrating bowel endometriosis: Correlation with gastrointestinal dysfunction and pain.

INTRODUCTION: Presence of deep infiltrating bowel endometriosis (DE) is associated with occurrence of dyschezia and gastrointestinal symptoms. The degree of the disease, the lesion length, and the location, that is, lesion-to-anal-verge distance (LAVD) of DE, as well as the severity of the symptoms appear to be correlated. Nevertheless, it is not yet known to what extent the size and LAVD of bowel DE influence the severity of gastrointestinal symptoms. The present study aims to evaluate a possible correlation of lesion location (LAVD) and size (according to the #Enzian classification) with preoperative symptoms. MATERIAL AND METHODS: In this prospective study, premenopausal patients with histologically confirmed DE undergoing modified limited nerve-vessel sparing rectal segmental bowel resection or full-thickness discoid resection were evaluated. Extent of endometriosis was defined according to the #Enzian classification during surgery. The primary outcome measure was the correlation between lesion size and location with the GI function impairment reflected by presurgical lower anterior resection syndrome (LARS) scores; the secondary outcome was differences in presurgical numeric rating scale pain scores of dyschezia, dyspareunia, and dysmenorrhea as well as the impact of concomitant DE of other locations on symptom intensity. RESULTS: Of 162 consecutive patients, 151 were included in the final analysis. No significant correlation was observed between lesion size (#Enzian compartments C1/C2/C3) or LAVD and GI dysfunction reflected by LARS-like symptoms (p = 0.314 and p = 0.185, respectively) or pain symptoms (dyschezia, p = 0.440; dyspareunia, p = 0.136; and dysmenorrhea p = 0.221). Furthermore, no significant correlation was observed between lesion size and GI dysfunction when merging two severity grades (#Enzian compartments C1 plus C2 vs. C3; p = 0.611). In addition, LAVD did not affect the degree of dyschezia (p = 0.892), dyspareunia (p = 0.395), or dysmenorrhea (p = 0.705). Finally, the presence of concomitant DE lesions infiltrating the vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) did not alter the severity of preoperative dyschezia (p = 0.493) or dysmenorrhea (p = 0.128) but showed a trend toward affecting gastrointestinal function (p = 0.078) and was significantly associated with dyspareunia (p = 0.035). CONCLUSIONS: In present study, we could not find a correlation between colorectal DE lesion size and location (LAVD) and gastrointestinal function impairment or intensity of dyschezia and dysmenorrhea. Additional involvement of vagina/rectovaginal space (#Enzian compartment A) and/or sacrouterine ligaments/parametrium (#Enzian compartment B) exerts a significant impact on the degree of dyspareunia in women with colorectal DE.

Combined Cystoscopic-Abdominal Versus Abdominal-Only Route for Complete Excision of Large Deep Endometriosis Nodules Infiltrating the Supratrigonal Area of the Bladder: A Comparative Study.

STUDY OBJECTIVE: Surgical excision of large deep endometriosis nodules infiltrating the bladder may be challenging, particularly when the nodule limits are close to the trigone and ureteral orifice. Bladder nodules have classically been approached abdominally. However, combining a cystoscopic with an abdominal approach may help to better identify the mucosal borders of the lesion to ensure complete excision without unnecessary resection of healthy bladder. This study aimed to compare classical excision of large bladder nodules by abdominal route with a combined cystoscopic-abdominal approach. DESIGN: Retrospective comparative study on data prospectively recorded in a database. Patients were managed from September 2009 to June 2022. SETTING: Two tertiary referral endometriosis centers. PATIENTS: A total of 175 patients with deep endometriosis infiltrating the bladder more than 2 cm undergoing surgical excision of bladder nodules. INTERVENTIONS: Excision of bladder nodules by either abdominal or combined cystoscopic-abdominal approaches. MEASUREMENTS AND MAIN RESULTS: A total of 141 women (80.6%) were managed by abdominal route and 34 women (19.4%) underwent a combined cystoscopic-abdominal approach. In 99.4% of patients, the approach was minimally invasive. Patients with nodules requiring the combined approach had a lower American Fertility Society revised score and endometriosis stage and less associated digestive tract nodules, but larger bladder nodules. They were less frequently associated with colorectal resection and preventive stoma. Operative time was comparable. The rate of early postoperative complications was comparable (8.8% vs 22%), as were the rates of ureteral fistula (2.2% vs 2.9%), bladder fistula (2.2% vs 0), and vesicovaginal fistula (0.7% vs 2.9%). CONCLUSION: In our opinion, the combined cystoscopic-abdominal approach is useful in patients with large bladder nodules with limits close to the trigone and ureteral orifice. These large deep bladder nodules seemed paradoxically associated to less nodules on the digestive tract, resulting in an overall comparable total operative time and complication rate.

Combined Robotic Transanal Transection Single-Stapled Technique in Ultralow Rectal Endometriosis Involvement Associated With Parametrial and Vaginal Infiltration.

OBJECTIVE: To describe a combined robotic and transanal technique used to treat ultralow rectal endometriosis in a 36-year-old patient with multiple pelvic compartments, which was responsible for infertility, dyspareunia, left sciatic pain, and severe dyschezia. DESIGN: Surgical video article. SETTING: The achievement of a perfect bowel anastomosis in patients with low rectal endometriosis could be challenging owing to technical and anatomic limitations [1]. By allowing a right angle rectotomy with a single-stapled anastomosis, the transanal transection single-stapled technique overcomes these technical difficulties ensuring a good-quality anastomosis with an easier correction of postoperative anastomotic leakage when it occurs [2,3]. INTERVENTIONS: The surgery starts by splitting the nodule in 3 components according to different anatomic structures involved (parametrium, vagina, and rectum). Parametrial and vaginal fragments are excised as previously described (Supplemental Videos 1) [4]. The rectal involvement is approached following several steps: isolation and cut of inferior mesenteric vessels (inferior mesenteric artery and inferior mesenteric vein) and left colic artery to obtain a proper colon mobilization; transanal rectotomy immediately below the lower limit of the nodule; extraction of the specimen through the anus (Supplemental Videos 2); proximal bowel segment transection 1 cm above the upper limit of the nodule; introduction of circular stapler anvil into the sigmoid colon; placement of 2 purse string to secure the anvil and at distal rectal cuff, respectively; connection of the anvil to the shoulder of circular stapler; stapler closing and firing with coloanal anastomosis formation; stapled line reinforcement by stitching; and integrity anastomosis test (Supplemental Videos 3). No preventive diverting stoma was performed in accordance with our policy [5]. CONCLUSIONS: Although no data are yet available in patients with endometriosis, the use of transanal transection single-stapled technique may be an interesting approach in patients with very low rectal endometriosis involvement.

Early Quality of Life Assessment After Segmental Colorectal Resection for Deep Infiltrating Endometriosis.

STUDY OBJECTIVE: Endometriosis is a benign condition afflicting women of reproductive age that significantly impacts their quality of life (QoL). Given its debilitating symptoms and prevalence, it is essential to define its proper management. In this study, we have assessed patient-reported outcomes among women having undergone segmental colorectal resection for deep infiltrating endometriosis. Any correlation between preoperative nutritional status and overall postoperative complications has also been analyzed. STUDY DESIGN: Prospective observational study. SETTING: Public medical center. PATIENTS: One hundred forty consecutive patients that had undergone segmental colorectal resection for DIE between November 2020 and October 2021 at IRCCS Sacro Cuore Don Calabria Hospital of Negrar of Valpolicella (Verona, Italy). INTERVENTIONS: Patient-reported outcomes were measured using data collected from the MD Anderson Symptom Inventory for gastrointestinal surgery patients and Euro-QoL Group EQ-5D-5L (EQ-5Q-5L) questionnaires, which were administered preoperatively (T0), at discharge (T1) and at 4 to 6 weeks after surgery (T2). Nutritional status was examined through the Mini Nutritional Assessment Short form and Prognostic Nutritional Index. MEASUREMENTS AND MAIN RESULTS: A significant improvement in the EQ-5Q-5L and MDASI-GI scores was noted between T0 and T2 (p <. 001 and p <. 001, respectively.) No statistically significant differences were found in scores at T2 between patients who had experienced postoperative complications and those who had not. No statistically significant association was observed between the presence of malnutrition and overall postoperative complications and their severity. CONCLUSION: This study confirms, through patient-reported outcomes, the pivotal role of surgery in improving the QoL at 4 to 6 weeks of women affected by endometriosis who have previously been unresponsive to medical therapy.

Feasibility of Intraoperative Proctosigmoidoscopy After Discoid Bowel Resection for Deep Infiltrating Endometriosis: A Pilot Multicenter Study.

STUDY OBJECTIVE: Although surgery is the gold standard treatment for pain refractory to medical management or partial occlusion owing to rectosigmoid endometriosis, surgical resection can be associated with major perioperative complications. From general surgery experience, intraoperative proctosigmoidoscopy has shown encouraging results as a feasible, safe, and effective technique in reducing the risk of complications related to intestinal anastomosis after segmental resection. Unfortunately, there are no studies evaluating its role after discoid resection for rectosigmoid endometriosis. DESIGN: A pilot, multicentric, observational, prospective, cohort study. SETTING: Two academic hospitals, from March 1 to December 31, 2022. PATIENTS: We enrolled all consecutive fertile-age patients affected by symptomatic endometriosis scheduled for laparoscopic discoid bowel resection. Inclusion criteria were (1) age between 18 and 50 years, (2) diagnosis of rectosigmoid endometriosis performed by transvaginal ultrasound and/or magnetic resonance imaging, and (3) women scheduled for laparoscopic discoid bowel resection of endometriosis at low risk of segmental resection. INTERVENTIONS: During data analysis, enrolled patients were divided into 2 study groups for comparisons based on whether or not the intraoperative proctosigmoidoscopy was performed upon surgeons' discretion after discoid resection for treating endometriosis, in addition to standard integrity tests. Primary outcome was the rate of intraoperative proctosigmoidoscopy success. Secondary study outcomes were the differences between the intraoperative proctosigmoidoscopy group and the nonintraoperative proctosigmoidoscopy group in (1) mean of total operative time and (2) rate of perioperative complications. MEASUREMENTS AND MAIN RESULTS: A total of 28 patients were enrolled and equally distributed in the 2 groups. The rate of intraoperative proctosigmoidoscopy success was 86%. No significant difference was reported between the 2 groups in terms of total operative time (p = .1) and intraoperative and postoperative complications (p = .5 and p = 1, respectively), with no surgical complication related to intraoperative proctosigmoidoscopy. CONCLUSION: Intraoperative proctosigmoidoscopy seems as a feasible and non-time-consuming intraoperative procedure in women undergone discoid resection for rectosigmoid endometriosis. Larger studies with longer follow-up period are necessary to confirm our findings and assess clinical benefits over standard procedure.

Risk factors for postoperative urinary retention in patients underwent surgery for benign anorectal diseases: a nested case-control study.

BACKGROUND: Postoperative urinary retention (POUR) is a common complication of anorectal surgery. This study was to determine the incidence of POUR in anorectal surgery for benign anorectal diseases, identify its risk factors, and establish a nomogram for prediction of POUR. METHODS: A nested case-control study was conducted. The clinical data of patients were collected, and the incidence of POUR was analyzed. Univariate analysis was used to identify the risk factors associated with POUR, and multivariate logistic regression analysis was used to determine independent risk factors for POUR. A nomogram for the preoperative prediction of POUR using a logistic regression model was developed (n = 609). RESULTS: The incidence of POUR after anorectal surgery for benign anorectal diseases was 19.05%. The independent risk factors for POUR were: female (P = 0.007); male with benign prostatic hyperplasia (BPH) (P = 0.001); postoperative visual analogue scale (VAS) score > 6 (P = 0.002); patient-controlled epidural analgesia (PCEA) (P = 0.016); and a surgery time > 30 min (P = 0.039). In the nomogram, BPH is the most important factor affecting the occurrence of POUR, followed by a postoperative VAS score > 6, PCEA, surgery time > 30 min, and sex has the least influence. CONCLUSION: For patients undergoing anorectal surgery for benign anorectal diseases, preventive measures can be taken to reduce the risk of POUR, taking into account the following risk factors: female or male with BPH, severe postoperative pain, PCEA, and surgery time > 30 min. Furthermore, we developed and validated an easy-to-use nomogram for preoperative prediction of POUR in anorectal surgery for benign anorectal diseases.

Evaluation and management of chronic anorectal and pelvic pain syndromes: Italian Society of Colorectal Surgery (SICCR) position statement.

Chronic pelvic pain is a hidden issue which needs to involve many different usually uncoordinated specialists. For this reason there is a risk that treatments, in the absence of well-defined pathways, common goals, and terminology, may be poorly effective. The aim of the present paper is to summarize the evidence on anorectal pelvic pain, offering useful evidence-based practice parameters for colorectal surgeons' daily activity. Analysis of chronic anorectal and pelvic pain syndromes, the diagnostic and clinical optimal needs for evaluation, and the innumerable low evidence treatments and therapeutic options currently available suggests that a multimodal individualized management of pain may be the most promising approach. The limited availability of dedicated centers still negatively affects the applicability of these principles.

[Implementation of fluorescent imaging technology in endovideosurgical treatment of colorectal endometriosis]. / Vnedrenie tekhnologii fluorestsentnoi vizualizatsii v endovideokhirurgicheskoe lechenie kolorektal'nogo endometrioza.

The article includes a clinical case of a patient with deep infiltrating endometriosis with rectum involving and using intraoperative controlled fluorescence in order to increase the radicality of surgery and improve the prognosis of the disease. Surgical excision of the endometrioitic nodules is the only effective way of treating patients with colorectal endometriosis in terms of relieving pain, improving quality of life and restoring reproductive function. The possible types of surgical interventions can be performed: endometrioid lesion shaving, discoid or circular intestinal resection with anastomosis. The extent of the operation is determined by the following morphological parameters: the number of endometrioid infiltrates of the intestinal wall, the size of each of them, the degree of involvement of the intestine circumference, the depth of the intestinal wall lesion, the distance from the level of anus to the endometriotic nodule and lymphatic dissemination.

[A Case of Perforated Rectal Cancer with Laparoscopic Low Anterior Resection].

We report a case of perforated rectal cancer with laparoscopic low anterior resection. Case: A 60-year-old man was transported to the hospital with a chief complaint of sudden lower abdominal pain. Computed tomography revealed wall thickening of the upper rectum and free air localized around the rectum and fecal mass in the mesorectum. He was diagnosed with perforated rectal cancer. Because of the early onset, young age, and ascites confined to the pelvic floor, we decided to perform laparoscopic low anterior resection(D3 dissection). Intraabdominal observation revealed tumor in the upper rectum with a large rectal perforation 3 cm proximal to the tumor. By using gauze and suction, we were able to complete the surgery with ingenuity laparoscopically. The postoperative course was good, and he was discharged 9 days after surgery. Postoperative pathological examination revealed pT4apN0sM0, pStage Ⅱb. Adjuvant chemotherapy of 8 courses of capecitabine was performed. There has been no recurrence 3 years after surgery.

Development of a Standardized Process for Transition to Adult Care in a Pediatric Colorectal Surgery Clinic.

BACKGROUND: As pediatric patients with colorectal diseases grow, it is important to address transition to adult practice. We aim to describe our center's transition process and early outcomes. METHODS: We developed a standardized process for transition to adult practice. An annual survey is given to parents and caregivers starting at age 12 that assesses knowledge of disease, independence with healthcare tasks, and confidence and interest regarding transition. After multidisciplinary review, those eligible are recommended for transition. Those not referred are provided with tools to help with areas of weakness. Outcomes were analyzed with descriptive and regression analyses (significance at p ≤ 0.05). RESULTS: A total of 116 patients were evaluated, with 80 patients (69.0%) recommended for transition. Median age at survey was 15.5 years [IQR: 13.7-18.1], and those recommended were older (16.6 years [IQR: 14.7-19.4] vs 13.5 years [IQR: 12.5-14.9], p < 0.001)). Primary diagnosis and gender were not associated with recommendation for transition. Overall, a minority (18.1%) were able to complete healthcare tasks; this correlated strongly with transition recommendation (26.3% vs 0.0%, p < 0.0001). On regression controlling for age, diagnosis, knowledge, and confidence, age (aOR 1.98, 95% CI 1.44-2.71) and confidence (aOR 3.78, 95% CI 1.29-11.11) independently predicted transition recommendation. CONCLUSION: A standardized approach may be effective in transitioning patients from pediatric to adult colorectal surgery practice. Patients who transition are more confident and can perform healthcare tasks independently; however, these skills are not essential prior to a recommendation of transition. LEVEL OF EVIDENCE: III.

Functional outcomes of bowel resection versus shaving or disc excision of colorectal endometriosis: a systematic review protocol.

INTRODUCTION: Endometriosis is a prevalent gynaecological condition for women of reproductive age worldwide. While endometriosis primarily involves the reproductive system, it can also infiltrate additional viscera such as the gastrointestinal tract. Patients with colorectal endometriosis can have severe symptoms that require surgical intervention. There are limited data available to guide the choice of resection technique based on the functional outcomes of bowel resection versus shaving or disc excision in treating colorectal endometriosis. This protocol aims to outline the methods that will be used in a systematic review of the literature comparing the functional outcomes of bowel resection to shaving and disc excision when surgically treating colorectal endometriosis. METHODS AND ANALYSIS: Papers will be identified through database searches, scanning reference lists of relevant studies and citation searching of key papers. Two independent reviewers will screen studies against eligibility criteria and extract data using standardised forms. Databases including MEDLINE, EMBASE and Cochrane will be searched from the beginning of each database until February 2024. The primary outcome is comparing the functional bowel outcomes between the different methods of surgical treatment. Secondary outcome will be quality of life, based on the Low Anterior Resection Syndrome score and the incidence of postoperative pain. A meta-analysis will be performed if the data are homogenous. ETHICS AND DISSEMINATION: This study does not require ethics approval. The results of the systematic review described within this protocol will be disseminated through presentations at relevant conferences and publication in a peer-reviewed journal. The methods will be used to inform future reviews. PROSPERO REGISTRATION NUMBER: CRD42023461711.

Sexual Function After Surgical Treatment for Benign Anorectal Disorders.

Benign anorectal diseases such as hemorrhoidal disease, anal fissure, anal pruritus, perianal abscess, and fistula are the most common ones. The aim of this study was to assess sexual function in patients after surgery for benign anorectal diseases. Sixty-one male patients with perianal fistulas, operated on at Department of General Surgery, Faculty of Medicine, completed a self-administered questionnaire including the International Index of Erectile Function (IIEF) score. The median IIEF score of the postoperative patients was significantly higher (24, range [10-25]) than that of preoperative patients (22, range [5-25]), p < .0001. Sexual function is significantly influenced by surgery for benign anorectal diseases.

Endoscopic sealing hemostasis with polyglycolic acid sheet and fibrin glue as a novel endoscopic hemostatic technique: a report of three cases.

Polyglycolic acid sheets and fibrin glue are routinely used in surgical procedures. Their usefulness in gastrointestinal endoscopy is mainly to prevent complications (bleeding, delayed perforation, stenosis, etc.) associated with procedures such as endoscopic submucosal dissection and endoscopic mucosal resection, with most reports on iatrogenic and secondary conditions. However, there are few reports on primary gastrointestinal diseases. Herein, we report three cases of gastrointestinal bleeding that were successfully treated with endoscopic hemostasis by sealing the lesions with polyglycolic acid sheets and fibrin glue. Case 1 was of an 83-year-old woman with a rare duodenal perforation that was treated with omental plugging who experienced subsequent bleeding from the greater omentum. Case 2 was of a 73-year-old woman with an acute hemorrhagic rectal ulcer that was difficult to treat even after performing standard endoscopic hemostasis techniques; however, surgery was avoided by sealing. Case 3 was that of an 89-year-old woman with a stercoral ulcer, treated curatively using a combination of sealing and argon plasma coagulation right from presentation based on the lessons learned from Cases 1 and 2. Endoscopic hemostasis using a polyglycolic acid sheet and fibrin glue may be a new treatment option for gastrointestinal bleeding particularly in refractory or rare causes.

Argon plasma coagulation: an effective treatment for solitary rectal ulcer syndrome.

BACKGROUND: Solitary rectal ulcer syndrome (SRUS) is a very rare benign defecation disorder characterized by distinct clinical features and histological findings. Conventional measures are often shown to be ineffective for the treatment of ulcers. Argon plasma coagulation (APC) has recently been shown to be an effective treatment method for SRUS that is refractory to conventional therapy. OBJECTIVES: Determine the efficacy of APC treatment for patients suffering from SRUS. DESIGN: Prospective, single center. SETTINGS: Gastroenterology department at a military hospital in Pakistan. PATIENTS AND METHODS: This prospective study included patients with symptoms of rectal bleeding diagnosed with SRUS. Patients were recruited on the basis of clinical, sigmoidoscopic, and histological findings from September 2022 to March 2023. All patients had received conventional treatment initially and were assessed for persistence of symptoms. APC was performed only for those patients who were refractory to standard treatment. MAIN OUTCOME MEASURES: Effectiveness of APC for resistant SRUS. SAMPLE SIZE: 99 patients. RESULTS: The 99 patients diagnosed with SRUS had a median (minimum-maximum) age of patients was 20 (9-41) years. All the patients had undergone conventional treatment, which included the use of laxatives, drinking plenty of water and practicing biofeedback. After this standard treatment, 19 patients (19.19%) recovered fully. However, the remaining 80 patients did not show improvement and underwent APC sessions, out of which 61 patients (76.3%) achieved complete healing of ulcers, while the remaining 19 (23.8%) had no improvement at all. None of the patients reported post session complications. CONCLUSION: APC is an effective therapy with very promising results for rectal ulcer hemorrhage. It also helps with ulcer healing and alleviates clinical symptoms. However, further controlled investigations are required to consolidate the use of APC in SRUS patients. LIMITATIONS: Single centered.

Operative Management and Outcome of Idiopathic Rectal Necrosis in an Octogenarian.

Idiopathic acute rectal necrosis (IARN) is a rare condition due to a robust rectal blood supply. This report describes an 83-year-old man presenting with septic shock due to distal sigmoid and complete rectal necrosis with perforation. He underwent emergent exploratory laparotomy, sigmoid and proximal rectum resection, and end sigmoid colostomy creation with delayed distal rectal evaluation. Bedside proctoscopy revealed pale, viable-appearing distal rectal mucosa on postoperative day 3. The patient had a protracted, complicated hospital stay but required no further operative intervention. Subsequent colostomy reversal was done 8 months postoperatively, and the patient did well and has been discharged with normal gastrointestinal function. Our successful conservative operative management of IARN deviates from previously described management in the literature which is emergent abdominoperineal resection. This conservative surgical strategy appears to have contributed to the patient's positive outcomes, highlighting the importance of considering a similar approach for future IARN cases.
