Abstract Introduction Scientific studies in Brazil grew around 10.7% compared to previous years. However, the level of quality of evidence has been decreasing. The aim in our study is to examine the meeting abstracts of the Brazilian congress of coloproctology and analyze the level of evidence in trends and variables. Methods A descriptive bibliometric study, working with secondary data to review scientific abstracts in the annals of the coloproctology congress from 2015 to 2019. Results A total of 1756 abstracts of the Brazilian Congress of Coloproctology were analyzed for 5 years (2015-2019). There was a higher trend of abstracts presented with lower levels of evidence (level of evidence 5: 52.3% and 3: 30%), being the majority composed of case reports (49.4%) and retrospective studies (30.4%). The last two years analyzed (2018: 55.2% and 2019: 59.3%) had a predominance above average of case reports. From 2017 to 2019 there was a significant decrease in the number of level 2 evidence studies (18.10%,11.80% and 5.50%), while the number of studies with level 5 evidence showed an increase (45.60%, 56.60% and 61.40%). Statistical analysis occurred in only 17%, with an important decrease for the last two years (2018: 13.6%; 2019: 12.1%). Conclusions Although the data of this study is from the Brazilian coloproctology point of view, they are important for the global scientific community, as they allow a quantitative evaluation of the relative contribution from the level of evidence of Brazilian coloproctology researchers to the scientific scenario.

Abstract Introduction Transanal Endoscopic Microsurgery (TEM) is a minimally invasive method for management of different proctologic conditions. Despite widespread use of this method, it is not used widely in Iran. This report is about to describe the application of TEM in managing different proctologic conditions in a tertiary colorectal referral center in Iran regarding methods and complications. Methods All of the patients' documents such as procedure, method, early postop complications and further operations were actively reviewed and the data were entered in to the database. Results Since 2012 till the end of 2020 chart review was done and 150 cases of TEM operation were found. The most frequent procedure that was done was resection procedure. Using different energy devices during surgery or suturing versus not suturing the defect were not associated with complication. There was a case of in hospital mortality and one case delayed perianal fistula following TEM. Measurement of lesion distance from anal verge was not significantly different using TEM or colonoscopy. Villous adenomas detected in colonoscopy were mostly associated with malignancy. In evaluated resected lesions most of cases had free base and distance from anal verge or using different energy devices were not associated with obtaining free base. Conclusion TEM is a safe minimal invasive procedure with acceptable complications that could be helped in managing different proctologic conditions and the results of reviewing our patients revealed the same results that is reported from other colorectal centers.

Abstract Introduction The cecum is the first part of the large bowel. Cecectomy is a sufficient treatment for some patients, avoiding overtreatment by ileocolic resection. PurposeThe goal of this study was to review a surgeon's experience with laparoscopic cecectomy and provide a technical video demonstration of this uncommon operation. Methods A retrospective chart review was conducted of all consecutive patients treated with laparoscopic cecectomy over a 16-year period. All operations were performed using a 3-trocar technique. The cecum was transected with 1 to 2 firings of a 60 millimeters linear stapler, preserving the ileocecal valve and ascending colon. Results 19 patients were identified including 12 females (63.2%). Median age was 42 years (range 16-84). Indication for surgery included appendiceal pathology in 12 patients (63.2%) and cecal abnormality in 7 (38.9%). There was no conversion to open surgery. Median intraoperative blood loss was 25 ml (range 0-150 ml) and no patient received a blood transfusion. No intraoperative or postoperative complication was noted. The median length stay was 1 day (range 0-6). Readmission rate was 0%. Final appendiceal histopathology revealed acute/chronic appendicitis in 5 patients, mucinous cystadenoma in 4 patients. Cecal histopathology revealed adenoma in 4 patients. Median follow-up was 16 months (range 4-53). Conclusions Laparoscopic cecectomy is a sufficient treatment for some patients with benign conditions of the appendix and cecum. It carries minimal morbidity. It should be considered as an alternative to segmental bowel resection in a select group of patients.

Abstract Objective To examine the effectiveness of nefopam on postoperative pain control after anorectal surgeries. Methods We retrospectively reviewed the electronic medical records of patients who underwent anorectal surgeries from January 2019 to March 2022 at two medical centers. The data were divided into nefopam and conventional groups. The primary outcome was the number of patients who requested additional opioids in the 24-h postoperative period. The secondary outcomes were numeric rating pain scores (NRPS) within a 24-h postoperative period and analgesic drugs-related side effects. Results Eighty-seven patients in the conventional group and 60 in the nefopam group were recruited. The nefopam group reported less additional opioid consumption than the conventional group in all dimensions of analysis, including overall, adjusted to anesthetic techniques and types of surgery. However, these did not reach statistical significance (P = 0.093). Only patients in the nefopam group who underwent hemorrhoidectomy under TIVA or spinal anesthesia significantly required fewer additional opioids (P = 0.016, 60% mean difference). Similarly, the 24-h postoperative morphine consumption was lower in the nefopam group (mean difference = −3.4, 95%CI: 0.72,6.08). Furthermore, significantly lower NRPS were reported in the nefopam group during the 12-18 h postoperative period (P = 0.009). On the other hand, analgesic drugs related side effects were similar in both groups. Conclusions The administration of nefopam after major anorectal surgery is beneficially evident in reducing postoperative opioid requirements.

Abstract Introduction Cancer is a disease that emerges as a result of abnormal cell proliferation and their propensity to spread from one bodily region to another. There are over a hundred different types of cancer that impact individuals all over the world. It is difficult to identify in the early stages, but there are certain warning signals that the cells will turn malignant. Quality of life (QOL) is described by the World Health Organisation as “individuals' perception of life, values, objectives, standards, and interests within the cultural framework of the social environment in which they live and in relation to their goals, expectations, standards, and concerns.” QOL assessment in health system is a multidimensional construct that can be measured by evaluating objective levels of health status filtered by the subjective perceptions and expectations of the individual. Aim and ObjectiveTo assess socio-demographic factors and quality of life among cancer patients in tertiary care hospital. Materials and MethodsA hospital-based prospective observational study was conducted at Guru Gobind Singh Medical College and Hospital Faridkot district, Punjab (India). The study was conducted for a period of six months after getting approval from Institutional Ethical Committee (IEC). Generic instrument, SF-36 was used to assess the QOL. The study was analyzed on SPSS version 26.0 software. Descriptive and analytical analysis was used to describe the results. Results Linear regression was conducted to see the relationship of physical functioning score with age and weight of the patients. The descriptive statistics shows the mean and standard deviation of the variable. The mean of physical functioning score was found to be (M = 27.82, SD = 15.635). The physical functioning score and age, weight of the patients in linear regression shows that the age and weight explain 17.5% Conclusion Treatment revealed that severe and moderate activities restricted nearly half of the assessed patients, with body pain interfering with employment and routine activities. According to the findings of the current study, QOL deteriorates as the disease progresses. Cancer unquestionably has a detrimental influence on patients' quality of life, which is connected to the illness process itself, the therapy administered, and the length of the disease.

Abstract Context Hirschsprung's disease (HD) is one of the commonest problems requiring surgery in children. More than 95% of children present during new-born period, when they are treated with leveling colostomy and are followed with pull-through surgery a few months later, once the child has gained adequate weight to withstand a major surgery. The commonest pull through surgery done is the Duhamel retro-rectal pull-through (DRPT) repair. Settings and Design This is a retrospective study of children who presented to one unit in our institute, a tertiary care referral hospital for children less than 12 years, with HD and underwent DRPT procedure during the period between July 2017 to June 2020. The children were evaluated after three years of follow-up for fecal incontinence and constipation. The study was conducted in children diagnosed with classical segment recto-sigmoid HD who underwent surgery. The children who were diagnosed with HD other than classical segment, who underwent primary pull through surgery and who underwent other repairs for HD were excluded from the study. Results Thirty-two children underwent DRPT procedure during the study period. Of them, five (15.6%) children were lost on follow-up and one (3.1%) child had expired in the immediate post-operative period. Twenty-six children were included in the study. The bowel function score was calculated. The mean age of definitive surgery was 4.2 years. The follow-up period was a minimum of three years. Only two children had a “good” score of eighteen and above. Nineteen children had a “fair” score of 13-17. Five children had a “poor” score of less than thirteen, and among them, two had a “very poor” score of less than nine. The mean BFS was 13.72. Conclusions Functional outcomes following Duhamel procedure are satisfactory, with 7.7% of children are in the fringe of requiring another surgery for constipation and pseudo-incontinence.

Abstract Inflammatory bowel disease (IBD) is a problem that directly affects the quality of life of patients suffering from this condition. Monitoring the serum level of infliximab (IFX) (TDM) is an important tool for guiding therapeutic decisions in IBD patients. The purpose of this study was to determine the significance of quantitatively measuring the serum level of IFX (TDM) and antibody to IFX (ATI). Methods and materials: Prospective observational study involving 40 IBD patients on IFX therapy, including 14 Proactive (week 06 of the induction phase) and 26 Reactive (maintenance phase). Immediately prior to the infusion, blood samples were drawn and measured using a Bulhlmann rapid test instrument. Serum concentrations of IFX were categorized as supratherapeutic (>7.0 micrograms/ml), therapeutic (between 3.0 and 7.0 micrograms/ml), and subtherapeutic (3.0 micrograms/ml). When the serum concentration of IFX was 3 mcg/ml (subtherapeutic), the ATI was measured. 25 patients with CD and 15 patients with UC were evaluated. Only three of the twenty patients with subtherapeutic serum levels had a positive ATI, and both were reactive; two had CD and one had UC. There was a statistically significant difference between reactive and proactive patients with respect to levels of CRP (p = 0.042), with proactive DNS patients suffering greater alterations in CRP and albumin.

Abstract Background and Aims Some studies have reported the coexistence of inflammatory bowel disease (IBD) and celiac disease (CD). However, the prevalence of anti-tissue transglutaminase antibodies (IgA and IgG) and their screening value in patients with IBD is not yet clear. This study aimed to assess the prevalence of IgA anti-tTG and its potential correlation with disease status in patients with IBD. Materials and Methods This cross-sectional study was conducted on 110 patients with confirmed IBD diagnosis at Ghaem Hospital, Mashhad, Iran. For each patient, all demographic and clinical data including age, extra intestinal manifestations, underlying diseases, types of diseases, and surgical history were collected. IgA anti-tissue transglutaminase titers were assessed by enzyme-linked immunosorbent assay. Results None of the patients with IBD were positive for IgA anti-tTG antibodies, with a mean titer of 3.31 ± 1.3 AU/mL. Also, the mean titers were not associated with age, gender and various disease clinical features including the disease history, underlying disease, diagnosis type, extraintestinal manifestations, and surgery history. Conclusion No significant prevalence pattern of IgA anti-tTG antibody was observed in patients with IBD. Accordingly, serological screening for CeD is not recommended in IBD patients, unless in a relevant clinical CeD suspicion.

Abstract The aim of our study is to evaluate the value of Argon Plasma Coagulation in the treatment of gastrointestinal vascular abnormalities. Patients and methods This is a descriptive and analytical retrospective study, from January 2009 to September 2020. 198 patients who have benefited from treatment with Argon Plasma Coagulation for vascular anomalies of the digestive tract divided into 2 groups: -Group A: Patients with radial rectitis lesions (n = 107). -Group B: Patients with lesions of digestive angiodysplasia (n = 91). Results The mean age of our patients was 64.95 ± 9.88 years [43 - 83] in group A, while in group B the mean age was 65.19 ± 14.29 years [40 - 91] with a clear male predominance in 72.5%. The majority of patients in group A were followed for prostate cancer in 33,8%, and 26.3% of patients in group B had chronic renal failure, followed by stomach cancer in 15.8%, and esophageal cancer in 10.5%. Clinical symptomatology was dominated by rectories in 40.2% in group A versus 46.8% in group B. Rectal involvement was dominated in group A in 98.1%, whereas in group B the lesions were mainly located in the stomach in 60.5%. The endoscopic evolution was favorable in all our patients with a clear improvement of rectal lesions and digestive angiodysplasia lesions. The total complication rate in our series was nil. Conclusion Plasma Argon coagulation is a very effective method in the endoscopic treatment of digestive haemorrhages with good tolerability and a low complication rate.

Abstract Introduction Chemotherapy response in early age-onset colorectal cancer patients is still controversial, and the results of chemotherapy response are unknown. Therefore, the purpose of this study is to determine the relationship between the age of colorectal cancer patients and histopathological features and chemotherapy response. Methods This is a prospective observational study. The subjects in this study were colorectal cancer patients in the Digestive Surgery division at Tertiary Hospital in West Java from September 2021 to September 2022. Results There were 86 subjects who underwent chemotherapy in accordance with the inclusion and exclusion criteria. Consisting of 39 patients of early age onset and 44 female patients. The most common histopathological feature in early age onset (EAO) and late age onset (LAO) was adenocarcinoma (25% and 46%, respectively). Stage III colorectal cancer affected 38 patients, while stage IV affected 48 patients. There was a significant relationship between early age onset and late age onset with histological features (p < 0.001). The patients with the highest chemotherapy response had stable diseases in EAO (17 patients) and LAO (20 patients). There was no statistically significant relationship between age, histological features, and stage of colorectal cancer and chemotherapy response (p > 0.05). The results of the ordinal logistic regression test showed no systematic relationship between chemotherapy response and age, histopathological features, gender, or cancer stage (p > 0.05). Conclusion There was no association between age and histopathologic features with chemotherapy response and there is no difference in chemotherapy response between early and late age onset.

Abstract Serrated polyposis syndrome is considered the most prevalent colonic polyposis syndrome in the world. Its importance has been increasingly discussed due to the significant increase in the risk of developing colorectal cancer in its affected individuals, similarly to other well-known polyposis syndromes, such as familial adenomatous polyposis. Serrated lesions of the colon play a major role in this syndrome represented by hyperplastic polyps, serrated sessile lesions and traditional serrated adenomas. Among these lesions, the sessile serrated lesion stands out, considered the main precursor lesion of the serrated pathway of colon carcinogenesis. Diagnosis of serrated polyposis syndrome is given through colonoscopy examination. Diagnostic criteria are: 1) 5 or more serrated lesions proximal to the rectum, all >4mm in size, with at least two >9mm in size; or 2) 20 serrated lesions of any size located anywhere in the large intestine, with >4 lesions proximal to the rectum. The ideal treatment is removal of all relevant serrated lesions by colonoscopy. In case of failure of endoscopic therapy, surgery is indicated. This manuscript is based on two case reports and a literature review and aims to broaden the discussion about the subject.

Abstract Introduction Perianal fistula is a common colorectal disease which is caused mainly by cryptoglandular disease. Although most cases are treated successfully by surgery, management of complex perianal fistulas (CPAF) remains a challenge with limited results in recurrence and sometimes associated with fecal incontinence. The CPAF treatment with autologous adipose-derived mesenchymal stem cells (ASCs) had become a research hotspot. The technique started to be used in the treatment of Crohn's disease (CD) fistulas, where the studies showed safe and goods result from the procedure. Cultured ASCs have been used but this approach requires the preceding collection of adipose tissue, time for isolation of ASCs and subsequent in vitro expansion, need for laboratory facilities, and expertise in cell culturing. These factors have been getting over by using the commercially available alternative, allogenic ASCs. Treatment with allogeneic ASCs has shown good results in patients with CD fistulas, however with the disadvantage of being expensive. Objective To show that the injection with freshly collected adipose tissue is an alternative to treatment with autologous or allogenic ASCs with several advantages. Methods: In this case report, we show our first experience in the treatment of CPAF with the application of collected adipose tissue in a tertiary referral hospital from Belo Horizonte, Brazil. Results The patient had a good postoperative recuperation with a complete fistula healing after 8 months without adverse effects. Conclusion Injection with freshly collected adipose tissue is a promising and apparently safe sphincter-sparing technique in the treatment of CPAF.

Abstract Introduction Rubber band ligation is a minimally invasive outpatient hemorrhoid treatment with low cost, low complication rates, and rapid realization. It is performed with the aid of an anoscope and uses a rubber ring that surrounds the hemorrhoidal nipple, causing compression of the vascular structures of the tissue, leading to necrosis and remission of the hemorrhoid. No device for training this essential procedure for treating this pathology has been identified in the literature. Therefore, we aim to develop a low-cost simulator for training hemorrhoidal rubber ligation. Methods The model was constructed using PVC pipe wrapped in neoprene fabric. Hemorrhoidal nipples and the pectineal line were also simulated using fabric and sewing threads. The procedure is performed with conventional anoscope and ligature forceps. Conclusion The device in question is a low-cost simulation model designed to train the skills required to perform a rubber band ligation and review the basic anatomy of the anal canal during anoscopy. Given these qualities, the model can be used for academic training due to its low cost and simplicity of application.
