Abstract Introduction Ileostomy formation is performed for multiple purposes related to intestinal pathology, such as obstructive malignant or benign tumors, inflammatory bowel diseases, intestinal ischemia, and, for the most part, as a protective stoma in high-risk anastomosis. The creation of this surgical opening, despite being considered a simple procedure, is undoubtedly followed by complications in certain cases. Materials and Methods We conducted an electronic literature search in the MEDLINE database using the PubMed search engine. A total of 43 articles were included in the present review. Results/Discussion Over the course of the present work, we were able to explore different types of complications that can arise in patients with an ileostomy. High-output stomas were found to be associated with dehydration and electrolyte imbalance. Skin-related morbidity was shown to be present in a great percentage of patients. More severe complications, such as peristomal pyoderma gangrenosum and necrosis, are less frequent and require urgent management. Several risk factors were identified in cases of retraction, obstruction, prolapse, and parastomal herniation. Conclusion Even though ileostomies may present numerous benefits in certain patients, they are also associated with many complications, which should be avoided and quickly managed, because they can severely affect the quality of life of the patients. Surveillance and follow-up by a multidisciplinary team is strongly advisable, bearing in mind that a good performance on the part of the responsible surgeon is also a key factor. pathology tumors diseases ischemia highrisk high anastomosis opening procedure engine 4 review ResultsDiscussion Results Discussion work ileostomy Highoutput High output imbalance Skinrelated Skin necrosis management retraction obstruction prolapse herniation managed followup follow up advisable factor

Abstract Pilonidal sinus is the term first used by Hodges in 1880 to describe a granulomatous lesion containing hairs. It has been previously described as hair extracted from an ulcer andreferredtoasJeep’s disease, in world war days. Pilonidal sinus is the condition in which a sinus or fistula is situated at a short distance from the anus and generally contains hairs. It is commonly observed in the sacrococcygeal region and a few other sites, such as the axilla, umbilicus, face, etc. Its presence elsewhere is uncommon. Predisposing factors are traumatized, hairy skin, which leads entry of the hair inside the wound, thus forming a sinus. A 31-year-old patient presented with discharging endoanal sinus tract, which, on exploration, turned out to be an endoanal pilonidal sinus containing hair tufts, a rare case. The patient complained of recurrent pus discharge and anal pain for 45 days, reporting history of travelling around 70 km daily in a two-wheeler vehicle. On first physical evaluation, a small endoanal bulge was found. It was located at 1 o’clock in lithotomy position (anterior), with purulent discharge and anterior anal fissure. For confirmation, an endoanal ultrasonography (USG) was performed, which showed a sinus tract containing internal echoes and gas bubbles with a small amount of pus. The sinus was explored, and a wide excision was made and left open for secondary healing. Pilonidal sinus of the anal canal is a rare entity, and it can be found in hairy patients who are used to going on long, daily rides on two wheeled vehicles. 188 hairs andreferredtoasJeeps andreferredtoasJeep s disease days sites axilla umbilicus face etc uncommon traumatized skin wound 31yearold yearold 31 year old exploration tufts case 4 7 twowheeler wheeler vehicle evaluation oclock o clock anterior, , (anterior) fissure confirmation USG (USG performed explored healing entity long vehicles 18 3 (anterior

Abstract Introduction Appendicitis is the surgical disease with the highest prevalence in emergency rooms. Its clinical and/or surgical complications are associated with the time course of symptoms, age, comorbidities, and stages of the disease. Objectives To analyze the demographic and clinical data of patients who underwent appendectomy for acute appendicitis in a tertiary referral hospital in the city of São Paulo and compare these data between services provided by the Public and Supplementary Health System. Methodology Retrospective analysis of data from electronic medical records of patients over 14 years old who underwent appendectomy for acute appendicitis at Hospital Santa Marcelina, both in the Public and Supplementary Health Systems from January 2015 to December 2017. Results A total of 536 patients were analyzed, 354 (66%) of whom were male with a general mean age of 29.85 years (14-81 years). The mean time from symptoms to seeking medical care was 53.84 hours. Regarding the phases of acute appendicitis, a greater number of cases of complicated disease was observed in patients operated on in the Public Health System (p < 0.0001), as well as the time course of symptoms (p = 0.0005) and Conclusion There was a predominance of male patients undergoing appendectomy for acute appendicitis, with longer time course of symptoms in those operated on in the Public Health System and a predominance of appendicitis in advanced stages (3 and 4) in this group. However, in this group there was no significant increase in the rate of postoperative infection, and the length of stay was shorter than that of patients operated on in the Supplementary Health System. rooms andor or comorbidities 1 Marcelina 201 2017 53 analyzed 35 66% 66 (66% 2985 29 85 29.8 1481 81 (14-8 years. . years) 5384 84 53.8 hours p 0.0001, 00001 0.0001 , 0 0001 0.0001) 0.0005 00005 0005 3 ( 4 However infection 20 5 6 (66 298 2 8 29. 148 (14- 538 53. 0000 0.000 000 (6 (14 0.00 00 (1 0.0 0.

Abstract Background Goblet cell carcinoma (GCC) of the appendix is a unique lesion that exhibits features of both adenocarcinoma and neuroendocrine tumors. Due to the rarity of this cancer, multiple grading (e.g., Tang, Yozu, and Lee) and staging systems (e.g., tumor, lymph nodes, and metastasis [TNM]) have been developed for classification. This study aimed to compare commonly used classification systems and evaluate the prognostic effectiveness immunohistochemical staining may or may not have for appendiceal GCC. Methods An electronic medical records review of patients who were diagnosed with GCC of the appendix in our hospital system from 2010 to 2020. The data were collected regarding the age at diagnosis, gender, initial diagnosis at presentation, operation(s) performed, final pathology results, current survival status, and year of recurrent disease or death year. Results Ten patients were evaluated. Seventy percent of the patients were above the age of 50 years at diagnosis. Postdischarge survival ranged from 1 month to 109 months postdiagnosis. Two patients expired from GCC at 13- and 54-months following diagnosis. When comparing the classification systems, Lee categorized more patients as high risk than Tang and Yozu. Immunohistochemical staining was analyzed using four staining methods: Ki67, E-cadherin, Beta-catenin, and p53. Tumor, lymph nodes, and metastasis staging has supportive evidence for worsening prognosis and overall survival secondary to the depth of invasion of the tumor. Conclusion Tumor, lymph nodes, and metastasis staging may be superior to the other classification systems in predicting overall mortality. Our study demonstrated that immunohistochemistry staining does not appear to have a significant impact in determining the prognosis for GCC of the appendix.

Abstract Introduction Returning to work is an important cancer recovery milestone. Permanent colostomy can be required for rectal cancer treatment and can significantly impact well-being. We aimed to evaluate the impact of permanent colostomy on health-related quality of life and return to work in patients with rectal cancer. Methods This was a retrospective cohort study on 23 employed patients receiving curative surgery for rectal cancer requiring permanent colostomy. Demographic and health-related quality-of-life questionnaires (the Colostomy Impact Score (CIS), the EORTC Quality of Life Questionnaire (QLQ)-C30, and the EORTC QLQ-CR29) were posted to eligible patients. Results On average, patients (10 female, 13 male, mean age 61.8 years) were 5.0 ± 3.5 years post-surgery. At the time of questioning, 73.9% had returned to work (21.7% changed their type of work), while 17.4% never returned to work. Of those that returned to work, 11.8% returned within 1 month of surgery, while 23.5% had not returned after 12 months. Comparison of CIS between patients that returned to the same work (14.6 ± 0.93), changed their work (13.0 ± 0.74), and did not return to work (14.3 ± 2.3) revealed no significant differences (p = 0.36). CIS did not correlate with days worked on return, or time to return to work (p > 0.05). Conclusion Returning to work following rectal cancer treatment with permanent colostomy is challenging, with 17.4% never returning to work. Of those who returned to work, 23.5% required more than 12 months.

Abstract Introduction and Objective In most cases, due to the failure of nonsurgical methods in the treatment of diseases related to the colon, it is necessary to perform colostomy as the main treatment method. However, this surgery can cause a wide range of physical, social, and psychological problems in patients. Therefore, in order to prevent and treat the complications of colostomy, it is necessary to adopt measures in the field of self-care and continuous education for patients to control the complications of the disease, seek treatment, and experience improvements in their quality of life. Additionally, considering the role of mobile health (mHealth) applications in facilitating continuous and effective training, and improving self-care for these patients, the aim of the present study was to design and evaluate an mHealth application for self-care of colostomy patients. Materials and Methods In the present applied research, first the functional requirements of the software were determined considering the self-care requirements of colostomy patients. Then, the software was designed based on object-oriented analysis, and according to it, the application was coded in Java and developed in the Android Studio environment. Finally, to evaluate the software, the opinions and comments of 5 gastroenterologists and 10 adult colostomy patients in the age range between 27 and 64 years who had at least a high school diploma were used as the basis of judgment at this stage. The instruments used in the evaluation included a checklist, derived from three standard questionnaires (the System Usability Scale [SUS], the mHealth App Usability Questionnaire [MAUQ], and the User Version of the Mobile Application Rating Scale [uMARS]) to measure the user-friendliness indicator, and a researcher-made checklist to measure the performance indicator of the various services provided. Results The services of the software developed include the provision of medical information and self-care instructions regarding colostomy surgery, as well as alerts for the user to schedule an appointment with a doctor and the time to take medications. Based on the results of the evaluation stage, the users were generally satisfied with the interface, services, and general features of the software. In general, the software was evaluated at the “acceptable” level, with a rate of 85%. Discussion and Conclusion Based on the findings of the current research, thesoftware developed can be significantly effective in facilitating the education of colostomy patients and improving their self-care. Proper and continuous self-care and education for colostomy patients is necessary to prevent and control complications resulting from surgery and to improve their quality of life. Therefore, in addition to patients, all health care staff, organizations, and associations which support colostomy patients can also use this software to educate patients and improve the care provided to them. cases colon method However physical social Therefore selfcare self disease life Additionally (mHealth training research Then objectoriented object oriented analysis environment Finally 1 2 6 stage SUS, SUS , [SUS] MAUQ, MAUQ [MAUQ] uMARS [uMARS] userfriendliness friendliness researchermade researcher made medications interface acceptable “acceptable level 85 85% selfcare. care. staff organizations them [SUS [MAUQ [uMARS 8

Abstract Objective Dyssynergic defaecation (DD) is an important cause of chronic constipation. In patients where conservative treatments fail, injections of botulinum toxin A (BTX-A) into the puborectalis and anal sphincter muscles can be effective. Complications of this procedure are reported to be rare and generally mild. This study aimed to identify the complication rates and short- to medium-term success rates of BTX-A injections as a treatment for DD. Methods A retrospective review was conducted on patients diagnosed with DD who had undergone BTX-A injections at a functional colorectal unit. Patient demographics, manometric assessment, conservative management, and injection technique were collected through a chart review. Subjective patient reports and comparison of pre- and postprocedure symptom scores were used to determine efficacy. Results The 21 patients included (24 procedures, with 3 patients receiving BTX-A on two separate occasions) all received stool modification and dietary advice, and 20 patients underwent pelvic floor physiotherapy, averaging 8 sessions. The injections were universally applied under general anesthetic, primarily targeting the anal sphincter and/or puborectalis muscles. There were 6 reports of faecal urge/incontinence, with all but one being resolved within weeks. The BTX-A injection was subjectively reported as beneficial in 19 cases, averaging 4.7 months (range 1-32) of improvement. Only 2 were sustained beyond 12 months. Despite overall improvements in symptom scores from pre- to postprocedure, none were statistically significant. Conclusion Following a course of conservative management, the BTX-A injection appears to be a safe treatment for DD, but only has short term efficacy.

Abstract Objective To describe the pro file of surgeons who treat patients with inflammatory bowel disease as well as the characteristics of inflammatory bowel disease care, unmet demands, and difficulties. Methods The research participants answered a Google Forms questionnaire. Results Of the 99 surgeons who participated in the survey, 84.5% were coloproctologists, 40% were from the southeastern region of Brazil, and 77.7% were male and had been working for more than 19 years. Regarding the healthcare sector, 63.6% of surgeons worked in both public and private clinics, and most clinically cared for up to 50 patients with inflammatory bowel disease and operated on up to 5 cases per year. Conclusion This is the first national study that aimed to identify the profile of surgeons working with inflammatory bowel disease in Brazil. The vast majority are experienced male coloproctologists, located in the southern and southeastern regions, who perform clinical and surgical treatment of these pathologies, with major surgeries being performed in large centers by a small number of surgeons. care demands difficulties questionnaire 9 survey 845 84 84.5 coloproctologists 40 Brazil 777 77 7 77.7 1 years sector 636 63 6 63.6 clinics year regions pathologies 8 84. 4 77. 63.

Abstract Purpose Laparoscopic techniques to treat pelvic organ prolapse are gaining popularity around the globe due to their low recurrence rates and better functional results compared to perineal techniques. However, the optimum surgical procedures are not yet determined. In the current research, we suggest a novel surgical approach, laparoscopic vaginal suspension with suture rectopexy, to treat multiorgan pelvic prolapse. Methods This prospective cohort trial was conducted from March 2018 to March 2022 and comprised 35 females with multiorgan pelvic organ prolapse with obstructed defecation symptoms. A residual rectal prolapse was still present despite the manual reduction of uterine prolapse. Patients’ conditions before and after the operation were monitored regarding the obstructed defecation score, sexual function, need for laxatives, anorectal manometry pressures, anorectal sensations, and recurrence. The mean follow-up duration was one year. Results Modified Longo score for obstructed defecation significantly decreased at six and twelve months after surgery. Additionally, a significant reduction was reported in the number of patients who needed laxatives at six and twelve months after surgery. Anorectal manometry pre- and post-surgery showed a significant elevation in the mean squeeze pressure and a decline in all rectal sensations. All parameters of the female sexual function scoring system increased postoperatively. No recurrence was reported during follow-up. Conclusion For multiorgan pelvic prolapse, laparoscopic vaginal suspension combined with suture rectopexy has excellent functional outcomes, minimal morbidity, and low cost. However determined research approach 201 202 3 symptoms Patients pressures sensations followup follow up year surgery Additionally pre postsurgery post postoperatively followup. up. outcomes morbidity cost 20 2

Abstract Introduction After the diagnosis of neoplasm of the middle and distal rectum, patients are often submitted to oncological treatment by neoadjuvant therapy. At the end of this treatment, those patients who show complete clinical response can choose, together with their physician, to adopt the watch-and-wait strategy; although it implies lower morbidity for the patient, this strategy is dependent on strict adherence to treatment follow-up for the early identification of any future local injury. Materials and Methods Survey of data from medical records and description, and discussion of case reports with a literature review in books and databases. Results We report the case of a 73-year-old patient diagnosed with moderately differentiated adenocarcinoma of the middle rectum, Stage II (cT3bN0M0), who presented complete clinical response after undergoing treatment with neoadjuvant therapy. Together with the assistant team, the watch-and-wait strategy was chosen. During the follow-up, an endoscopic examination showed a vegetating at the proximal limit of the tumor scar. We chose to perform submucosal endoscopic dissection. The report of the anatomopathological examination evidenced a serrated adenoma with narrow margins free of neoplasia. Conclusion Patient adherence to cancer treatment using the watch-and-wait strategy is essential for the early identification of new local lesions. After resection of the lesion identified in the tumor scar site as a neoplasm-free lesion, it is consistent to think that this lesion would be the origin of the neoplasm, given the adenomatous origin. rectum therapy choose physician watchandwait watch wait followup follow up injury description databases 73yearold yearold 73 year old cT3bN0M0, cT3bN0M0 cTbNM , cT bN M (cT3bN0M0) team chosen followup, up, dissection neoplasia lesions neoplasmfree 7 cT3bN0M (cT3bN0M0 (cT3bN0M

Abstract Introduction Colorectal cancer (CRC) is the second most prevalent cancer in the world, and the fecal immunochemical test (FIT) can be mentioned among the CRC screening methods based on the detection of occult blood in the feces, which may indicate upper gastrointestinal (UGI) malignancies; therefore, patients with a positive FIT but normal colonoscopy may be considered for a UGI endoscopy. Materials and Methods The present study was conducted on patients with a positive FIT who were submitted to colonoscopy with normal results. They subsequently underwent endoscopy for the detection of UGI disorders. Results We included 121 patients (64.5% of women and 35.5% of men; average age: 58.85 ± 12.93 years), 72.7% of whom were positive for Helicobacter pylori. The predominant result of the UGI endoscopy was normal, followed by erythema of the gastric mucosa, and anemia and dyspepsia were the most common clinical findings. The most common pathological result was chronic gastritis, followed by acute gastritis. Only one patient presented stomach cancer (adenocarcinoma). Conclusion Considering the small prevalence of cancer in the UGI endoscopies of patients with positive FIT and normal colonoscopy, to the performance of UGI endoscopy in these patients may not be necessary.

Abstract Objective To identify if there is an association between pelvic entry and pelvic outlet diameters with increased positive circumferential resection margin (CRM) in rectal cancer. Introduction Positive CRMin rectalcancerisa majorpredictor forlocal anddistant recurrence. Pelvic diameters may be related to the difficulty of dissection, as well as intrinsic tumor characteristics such as tumor size, location, distance from the anal margin, and T stage, which may compromise the integrity of the mesorectum and circumferential margin involvement. Methods A retrospective review of the patient’s medical records who underwent surgical resection of rectal adenocarcinoma from January 2012 to June 2022 was performed. The patient’s preoperative staging, operative characteristics, and histopathologic outcomes were gathered from the medical records. Preoperative MRI scanning was done in all patients. MRI pelvimetry was done by two observers. CRM involvement was recorded as stated in the pathology report. Pelvimetry variables were dichotomized according to their mean values for correlation analysis. The odds ratio (OR) was calculated from a binary logistics regression model to assess the relation between the positive CRM and the independent variables. Results A total of 78 patients were included in this study. A positive CRM was reported in 10 patients (12.8%). BMI >27.4 + 6.6 (p = 0.02), positive extramural vascular invasion (p = 0.027), positive CRM by MRI scanning (p = 0.004), and anal sphincter involvement (p = 0.03) were associated with positive CRM. Pelvimetry values were not associated with a positive CRM. Conclusion No association was found between the pelvic diameters measured by MRI pelvimetry with a positive CRM.

Abstract Introduction Gender inequality occurs in all spheres of society, which is no different in the medical field. Abstract presentations in congress are the vanguard of scientific knowledge, an integral part of topic discussion, and, ideally, culminate in the publication of these works as complete manuscripts. Objective The objective of this study is to evaluate the role played by women in the presentation of scientific works at the Brazilian Society of Coloproctology congress and in the works published from these presentations. Methods The bibliometric evaluation of the presented abstracts in the editions from 2015 to 2018 of the Brazilian Congress of Coloproctology was used, along with the works later published from these presentations. Gender identification data was extracted from the authors of the abstracts through their names and research for conference on the Lattes and Google Scholar platforms. The collected data was on the number of female participants and their order of authorship of abstracts and publications, evaluating possible changes when publication occurs. Results Atotal of 1,336 abstracts were analyzed, with 91.6% of female authors. When publication occurs, women’s presence dropped to 75.2% and suffered a change of order in the position of authorship to one of lesser relevance in 38.1%. Conclusion Women’s participation occurs in most abstracts. However, this proportion undergoes unfavorable changes when these works are published, either by changing the order of authorship, when women leave main positions and become coauthors, or are removed from the complete manuscript’s publication. society field knowledge discussion ideally manuscripts 201 used platforms publications 1336 1 336 1,33 analyzed 916 91 6 91.6 womens s 752 75 2 75.2 381 38 38.1% Womens Women However coauthors manuscript 20 133 33 1,3 9 91. 7 75. 3 38.1 13 1, 38.

Abstract As it is an infrequent etiology, the diagnosis of perianal tuberculosis is challenging, especially in the absence of a pulmonary focus. TB should be considered in the differential diagnosis of perianal ulcers, fistulas, abscesses, mainly in non-healing and recurrent anal lesions. Treatment with anti-TB agents can provide complete recovery. Furthermore, these lesions are often diagnosed later after complete histopathological and mycobacterial results, where the benefit of avoiding morbid multiple surgeries by effective anti-TB treatment is lost. We reported a rare case of an immuno-competent patient with perianal TB, which was the first manifestation of the disease. A fit-and-well man in his 20s presented a large perianal abscess. Unexpectedly, his chest X-ray showed a rounded hyper-transparency in the left lung. The abscess was drained. Posterior investigation with culture analysis from pus swabs and sputum revealed the presence of Mycobacterium tuberculosis complex infection. After completing the 6 months of oral administration of anti-TB drugs, the patient was asymptomatic. By highlighting this unusual manifestation, we aim to improve clinicians' awareness of perianal TB, facilitating early recognition and appropriate management. etiology challenging focus ulcers fistulas abscesses nonhealing non healing antiTB anti recovery Furthermore results lost immunocompetent immuno competent disease fitandwell fit well s Unexpectedly Xray X ray hypertransparency hyper transparency lung drained infection drugs asymptomatic clinicians management

Abstract Introduction Colorectal cancer is the third most common malignant neoplasm worldwide, with ~ 150 thousand new cases each year. Screening policies have brought significant progress due to the possibility of early diagnosis and polyp resection. Therefore, there is a need for continuous evaluation of the quality of colonoscopies based on well-established criteria in the literature. Materials and Methods The present retrospective study assesses the quality of colonoscopies performed at a tertiary hospital, comparing resident physicians with their preceptors. A total of 422 preceptor exams and 115 resident exams were evaluated, with a comparison of the adenoma detection rate, cecal intubation rate, examination time, and bowel preparation quality. Results The adenoma detection rate in the exams performed by preceptors was of 46.9%, while in those performed by residents, it was of 35.2% (p = 0.038). The cecal intubation rate was of 98.6% in the preceptor group and of 94.8% in the resident group (p = 0.025). The median total examination time was of 13 minutes and 42 seconds in the preceptor group and of 19 minutes and 22 seconds in the resident group (p < 0.005). Conclusion During their training, resident physicians perform an adequate number of colonoscopies, which enables them to achieve adenoma detection rates, cecal intubation and examination times within the limits proposed by the literature. worldwide 15 year resection Therefore wellestablished well established literature hospital 11 evaluated 469 46 9 46.9% residents 352 35 2 35.2 p 0.038. 0038 0.038 . 0 038 0.038) 986 98 6 98.6 948 94 8 94.8 0.025. 0025 0.025 025 0.025) 1 4 0.005. 0005 0.005 005 0.005) training rates 46.9 3 35. 003 0.03 03 98. 94. 002 0.02 02 000 0.00 00 46. 0.0 0.
