Abstract Introduction The purpose of this retrospective bibliometric study was to assess the discrepancies between coloproctology surgery meeting abstracts and subsequent full-length manuscript publications. Methods Abstracts presented at the Brazilian Congress of Coloproctology Surgery from 2015 to 2019 were compared with matching manuscript publications. Discrepancies between the abstract and therefore the subsequent manuscript were categorized as major (changes within the purpose, methods, study design, sample size, statistical analysis, results, and conclusions) and minor (changes within the title, authorship, and number of female authors) variations. Results The conversion rate of abstracts in published manuscripts was 6,9% (121 abstracts). There were inconsistencies between the study title (66,1%), authorship (69,5%), study design (3,3%), sample size (39,2%), statistical analysis (24,8%), results (25,6%), and conclusions (12,4%) of manuscripts compared with their corresponding meeting abstracts. Conclusion As changes occur before manuscript publication of coloproctology surgery meeting abstracts, caution should be exercised in referencing abstracts or altering surgical practices based on abstracts content.

Abstract Introduction The pathophysiology of appendicitis likely stems from obstruction of the appendiceal orifice leading to an increase in intraluminal and intramural pressure, resulting in small vessel occlusion and lymphatic stasis. Organ supplied by an end artery, such as the appendix, are more prone to the deleterious effects of arterial occlusion. The continuous cigarette smoking might be associated with a greater risk for developing atherosclerosis. Objectives The aim is to evaluate the effect of cigarette smoking on the incidence of complications of acute appendicitis. Methods Patients suffered from symptoms and signs suggesting acute appendicitis were examined and investigated. a multiple items collecting data questionnaire including smoking status and exclusion of confounders were constructed. The complicated and non-complicated appendicitis were compared concerning their smoking status. Results Seventy-two Patients were included in this study; the mean age of studied patients was 24.13 ± 9.1 years. The age of 57% of patients were below the mean age and considered as younger age group, while the remaining 43% of patients were equal or above the mean age which considered as older age group. Thirty-three percentage of patients had ≥ 36 hours prehospital delay and considered as delay group, while the remaining 67% of patients had < 36 hours prehospital delay which considered no delay group, males constitute 54% of studied patients. smokers constitute 29% while the remaining 71% of studied patients were nonsmokers, 61.9% of the smokers developed complications of appendicitis. Conclusion Perforated acute appendicitis is higher among current tobacco smokers.

Abstract Inflammatory bowel disease (IBD) is a chronic condition that affects the digestive tract and can lead to inflammation and damage to the intestinal lining. IBD patients with cancer encounter difficulties since cancer treatment weakens their immune systems. A multidisciplinary strategy that strikes a balance between the requirement to manage IBD symptoms and the potential effects of treatment on cancer is necessary for effective care of IBD in cancer patients. To reduce inflammation and avoid problems, IBD in cancer patients is often managed by closely monitoring IBD symptoms in conjunction with the necessary medication and surgical intervention. Anti-inflammatory medications, immunomodulators, and biologic therapies may be used for medical care, and surgical options may include resection of the diseased intestine or removal of the entire colon. The current study provides a paradigm for shared decision-making involving the patient, gastroenterologist, and oncologist while considering recent findings on the safety of IBD medicines, cancer, and recurrent cancer risk in individuals with IBD. We hope to summarize the pertinent research in this review and offer useful advice.

Colorectal cancer (CRC) is among the most diagnosed malignancies worldwide, and it is also the second leading cause of cancer-related deaths. Despite recent progress in screening programs, noninvasive accurate biomarkers are still needed in the CRC field. In this study, we evaluated and compared the urinary proteomic profiles of patients with colorectal adenocarcinoma and patients without cancer, aiming to identify potential biomarker proteins. Urine samples were collected from 9 patients with CRC and 9 patients with normal colonoscopy results. Mass spectrometry (label-free LC‒MS/MS) was used to characterize the proteomic profile of the groups. Ten proteins that were differentially regulated were identified between patients in the experimental group and in the control group, with statistical significance with a p value ≤ 0.05. The only protein that presented upregulation in the CRC group was beta-2-microglobulin (B2M). Subsequent studies are needed to evaluate patients through different analysis approaches to independently verify and validate these biomarker candidates in a larger cohort sample.

Abstract Introduction Anorectal fistulas are some of the commonest surgical proctologic disorders treated by surgeons. Despite the recent introduction of various sphincter preserving techniques, the search for the optimal operation continues. The purpose of this study was to determine the predictors of long-term healing for the endorectal advancement flap Methods A retrospective review of a single surgeon experience with the endorectal advancement flap for anorectal fistulas over an 18-year period. The impact of various patient and fistula related factors were analyzed for their impact on the primary endpoint of long-term fistula healing Results 87 patients underwent endorectal advancement flap (Male/Female 42.5/57.5%). Median age was 41 years. Sixty-nine patients (79.3%) had anal fistula while 18 patients had rectal fistula (20.7%). An anterior based fistula was noted in 45 patients (51.7%). The most common etiology was cryptoglandular disease (87.4%). The median operative time was 75 minutes (range 36-250). Postoperative septic complications were noted in 4 patients (4.6%). Fistula healing was documented in 80 patients (93%). During a median follow-up of 4 months (range 1-38, 1 patient lost to follow-up), recurrence was noted in 8 patients (9.3%), yielding an overall long-term success rate of 83.7%. The long-term healing rate was higher in patients with fistulas from cryptoglandular etiology (86.6%) compared to fistulas from other etiologies (63.6%) [p = 0.027]. Conclusions The endorectal advancement is associated with a high healing rate, a low postoperative septic complication rate, and infrequent risk for recurrence. Long-term healing without recurrence is achieved more frequently in patients with cryptoglandular etiology of the fistula compared to patients with non-cryptoglandular etiology.

Abstract Introduction McKittrick-Wheelock syndrome is a rare entity characterized by chronic diarrhea, acute kidney injury, and hydroelectrolytic imbalance associated with a large rectal tumor, frequently a villous adenoma. Case report A 69-year-old male with chronic diarrhea with mucus. He underwent a colonoscopy with biopsies, reporting adenocarcinoma of the rectum in situ, and underwent a robot assisted intersphincteric resection with colo-anal anastomosis and a protecitive ileostomy. Discussion Described in 1954, this syndrome is manifested by electrolyte imbalance and acute renal injury secondary to diarrhea associated with a rectal villous adenoma, often with long lasting symptoms. The most frequent symptom being watery diarrhea with mucus. The definitive treatment consists of surgical resection. Conclusion Although this is a rare pathology, it should be considered as a differential diagnosis in cases of chronic diarrhea associated with water and electrolyte disorders.

Abstract Objectives To evaluate the complete response (CR) rate and surgeries performed in patients with rectal adenocarcinoma who underwent neoadjuvant therapy (NT) at Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo and at Hospital São Paulo, in Ribeirão Preto, from January 2007 to December 2017. Methods We evaluated 166 medical records of patients with locally advanced rectal adenocarcinoma (T3, T4 or N + ) who underwent NT. The regimen consisted of performing conventional (2D) or conformational (three-dimensional-3D/ radiotherapy with modulated intensity – IMRT) at a dose of 45-50.4Gy associated with capecitabine 1650mg/m2 or 5-fluorouracil (5FU) and leucovorin (LV). The following variables were analyzed: gender, age, pretreatment stage, radiotherapy, CR index, local and distant recurrence rates. Surgical treatment and complications were also evaluated. Results The CR index was 28.3%. Patients treated with 3D/IMRT radiotherapy had a higher rate of CR (36.3% x 4.8%; p < 0.001), higher rates of clinical follow-up (21% x 0%; p < 0.001), lower surgery rates (79% x 100%; p < 0.001), higher rates of transanal resection (37.1% x 9.5%; p = 0.001), lower rates of abdominal rectosigmoidectomy (25.8% x 50%; p = 0.007) and lower rates of abdominoperineal resection of the rectum (16.1% x 40.5%; p = 0.002), when compared to patients treated with 2D radiotherapy. Conclusion Modern radiotherapy techniques such as 3D conformal and IMRT, by offering greater adequacy and precision of treatment, could result in better local control and less toxicity in organs at risk, enabling organ preservation strategies and less invasive approaches in selected cases.
摘要目的评价2007年1月至2017年12月在圣保罗大学医学院Clínicas医院和圣保罗医院接受新辅助治疗(NT)的直肠腺癌患者的完全缓解率(CR)和手术情况。方法对166例局部晚期直肠腺癌(T3、T4或N +)患者行NT治疗的病历进行评估，治疗方案包括常规(2D)或构象(三维- 3d /调强放疗- IMRT)，剂量为45-50.4Gy，卡培他滨1650mg/m2或5-氟尿嘧啶(5FU)和亚叶酸素(LV)。分析以下变量:性别、年龄、预处理分期、放疗、CR指数、局部和远处复发率。并对手术治疗及并发症进行了评价。结果CR指数为28.3%。接受3D/IMRT放疗的患者CR率更高(36.3% x 4.8%;p & lt;0.001)，更高的临床随访率(21% x 0%;p & lt;0.001)，手术率较低(79% x 100%;p & lt;0.001)，经肛门切除率较高(37.1% x 9.5%;P = 0.001)，腹部乙状结肠切除术的发生率较低(25.8% x 50%;P = 0.007)和较低的腹会阴直肠切除术率(16.1% x 40.5%;p = 0.002)，与接受二维放疗的患者相比。结论三维适形放疗和IMRT等现代放射治疗技术，通过提供更充分和精确的治疗，可以更好地局部控制和减少对危险器官的毒性，使器官保存策略和更少的侵入性成为可能。

Abstract Human papillomavirus (HPV) infection is one of the most common sexually transmitted viral diseases. A descriptive cross-sectional study was conducted with the purpose of clinically and epidemiologically characterizing anal HPV infection in patients who attended the Benign Orificial Pathology Consultation of the Coloproctological Unit at the Dr. “Antonio María Pineda” Central University Hospital, during the period March 2022 - February 2023, by selecting 288 patients whose average age was 47.09 ± 14.61 years, being the 41-50 years old group (29.17%) and the 51-60 years old group (19.44%) the most affected groups by pathologies of the anal region, with a predominance of male (54.17%). The sociodemographic characteristics with the highest frequency included married (48.61%) and single (47.22%); secondary level of education (44.44%) and traders (18.05%) and housewives (15, 28%) as predominant occupations. The risk factors were represented by onset of sexual intercourse between 16-20 years of age (65.28%), heterosexuality (91.67%), 22.22% reported having anal sex and 5.56% oral sex. Likewise, 5.56% were reported with a history of genital HPV and 4.17% were HIV positive. In addition, 48.61% stated not to use condoms. The initial clinical diagnosis included hemorrhoidal disease (30.55%), anal fistula (25%) and anal fissure (18.05%), and one patient (1.39%) with anal HPV infection. Anal cytology results showed 8.33% flat epithelial cells with cytopathic changes suggestive of HPV infection and 1.39% squamous cells with cytopathic changes suggestive of HPV infection: 50% mild inflammatory negative for malignancy and 33.33% flat epithelial cells without atypia. In conclusion, the anal cytology investigation should continue to determine the actual frequency of anal HPV infection.
摘要人乳头瘤病毒(HPV)感染是最常见的性传播病毒性疾病之一。在2022年3月至2023年2月期间，通过288例平均年龄为47.09±14.61岁的患者，对Antonio María Pineda博士中央大学医院直肠科良性口腔病理会诊的患者进行了一项描述性横断面研究，目的是对肛门HPV感染的临床和流行病学特征进行分析。肛门区病变以41 ~ 50岁组(29.17%)和51 ~ 60岁组(19.44%)为主，以男性居多(54.17%)。频率最高的社会人口特征为已婚(48.61%)和单身(47.22%);中等教育程度(44.44%)、贸易商(18.05%)及家庭主妇(15.28%)为主要职业。发生性行为的危险因素为16-20岁(65.28%)、异性恋(91.67%)、肛交(22.22%)和口交(5.56%)。同样，5.56%的人报告有生殖器HPV病史，4.17%的人报告HIV阳性。此外，48.61%的人表示不使用避孕套。临床首发诊断为痔疮病(30.55%)、肛瘘(25%)、肛裂(18.05%)，肛门HPV感染1例(1.39%)。肛门细胞学检查结果显示，8.33%的扁平上皮细胞伴有HPV感染的细胞病变，1.39%的鳞状细胞伴有HPV感染的细胞病变，50%的恶性轻度炎症阴性，33.33%的扁平上皮细胞无异型性。总之，肛门细胞学调查应继续确定肛门HPV感染的实际频率。

The sociodemographic characteristics with the highest frequency included married (48.61%) and single (47.22%); secondary level of education (44.44%) and traders (18.05%) and housewives (15, 28%) as predominant occupations. The risk factors were represented by onset of sexual intercourse between 16-20 years of age (65.28%), heterosexuality (91.67%), 22.22% reported having anal sex and 5.56% oral sex. Likewise, 5.56% were reported with a history of genital HPV and 4.17% were HIV positive. In addition, 48.61% stated not to use condoms. The initial clinical diagnosis included hemorrhoidal disease (30.55%), anal fistula (25%) and anal fissure (18.05%), and one patient (1.39%) with anal HPV infection. Anal cytology results showed 8.33% flat epithelial cells with cytopathic changes suggestive of HPV infection and 1.39% squamous cells with cytopathic changes suggestive of HPV infection: 50% mild inflammatory negative for malignancy and 33.33% flat epithelial cells without atypia. In conclusion, the anal cytology investigation should continue to determine the actual frequency of anal HPV infection.","PeriodicalId":15408,"journal":{"name":"Journal of Coloproctology","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135393891","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Stomas are essential for colorectal surgery and are widely used not only for selected cases for bowel obstructions but also in rectal cancer operations to divert stool away from low rectal anastomosis. On the other hand, complications with stomas/ stomas reversal are not uncommon. In this study, we aimed at studying the frequency and the predictors of temporary stomas being permanent, and the contributing factors of surgical stoma/stoma closure related complications. In our cohort, only about 40% of the patient closed their initially planned temporary stomas. The occurrence of intestinal leak, wound sepsis, or any type of morbidity with 30 days of operation were significant predictors of permanent stomas. In addition, alarmingly although Hartmann's procedure was uncommon in our practice, only 9% of those who underwent Hartmann's have had it reversed. Moreover, the only factor that significantly increased stoma related complications was having an end colostomy. There was a tendency toward late closure of stomas with median 8.2 months, however early closure did not correlate to complications. In conclusion, further studies are needed to delineate the low rate of stoma closure. Patients who develop postoperative complications, even wound sepsis, would be at a higher risk of living with permanent stomas. Hartmann's procedures are commonly associated with stoma problems, and reluctance to reverse the stomas.

Abstract Purpose Colorectal cancer (CRC) is one of the most fatal tumors worldwide. In Egypt, most CRC cases occur in individuals > 40 years old. TUG1 has been proved to be disrupted in different malignancies and may have a critical role in tumor progression, invasion, and metastasis. However, its role in CRC has not been adequately studied. Materials / Methods Quantitative real-time polymerase chain reaction (PCR) was used to evaluate the expression levels of long non-coding RNA (LncRNA) taurine upregulated gene 1 (TUG1), in nonmetastatic and metastatic CRC tissues and adjacent noncancerous tissues as control. Results LncRNA TUG1 expression was significantly upregulated in both nonmetastatic and metastatic CRC tissues, in comparison with the adjacent noncancerous tissue. It was found that TUG1 could have a possible prognostic role in CRC, by comparing the sensitivity and specificity of TUG1 with those of CEA and CA19–9. Conclusion The results of the current study suggest that the LncRNA TUG1 participates in the malignant behaviors of CRC cells.
