Abstract Background Colectomy with transanal ileal pouch-anal anastomosis (taIPAA) is a surgical technique that can be used to treat benign colorectal disease. Ulcerative colitis is the most frequent inflammatory bowel disease (IBD) and although pharmacological therapy has improved, colectomy rates reach up to 15%. The objective of this study was to determine anastomotic leakage rates and treatment after taIPAA as well as short- and long-term pouch function. Methods We conducted a retrospective analysis of a prospective database of all patients undergoing taIPAA at an academic tertiary referral center in Germany, between 01/03/2015 and 31/08/2019. Patients with indications other than ulcerative colitis or with adjuvant chemotherapy following colectomy for colorectal carcinoma were excluded for short- and long-term follow up due to diverging postoperative care yet considered for evaluation of anastomotic leakage. Results A total of 22 patients undergoing taIPAA during the study time-window were included in analysis. Median age at the time of surgery was 32 ± 12.5 (14–54) years. Two patients developed an anastomotic leakage at 11 days (early anastomotic leakage) and 9 months (late anastomotic leakage) after surgery, respectively. In both patients, pouches could be preserved with a multimodal approach. Twenty patients out of 22 met the inclusion criteria for short and long term follow-up. Data on short-term pouch function could be obtained in 14 patients and showed satisfactory pouch function with only four patients reporting intermittent incontinence at a median stool frequency of 9–10 times per day. In the long-term we observed an inflammation or “pouchitis” in 11 patients and a pouch failure in one patient. Conclusion Postoperative complication rates in patients with benign colorectal disease remain an area of concern for surgical patient safety. In this pilot study on 22 selected patients, taIPAA was associated with two patients developing anastomotic leakage. Future large-scale validation studies are required to determine the safety and feasibility of taIPAA in patients with ulcerative colitis.

Abstract Background Early detection of colorectal carcinoma (CRC) would help to identify tumors when curative treatments are available and beneficial. However, current screening methods for CRC, e.g., colonoscopy, may affect patients’ compliance due to the uncomfortable, invasive and time-consuming process. In recent decades, methylation profiles of blood-based circulating tumor DNA (ctDNA) have shown promising results in the early detection of multiple tumors. Here we conducted a study to investigate the performance of ctDNA methylation markers in early detection of CRC. Results In total, 742 participants were enrolled in the study including CRC (n = 332), healthy control (n = 333), benign colorectal disease (n = 65) and advanced adenoma (n = 12). After age-matched and randomization, 298 participants (149 cancer and 149 healthy control) were included in training set and 141 (67 cancer and 74 healthy control) were in test set. In the training set, the specificity was 89.3% (83.2–93.7%) and the sensitivity was 88.6% (82.4–93.2%). In terms of different stages, the sensitivities were 79.4% (62.1–91.2%) in patients with stage I, 88.9% (77.3–95.8%) in patients with stage II, 91.4% (76.9–98.2%) in patients with stage III and 96.2% (80.3–99.9%) in patients with stage IV. Similar results were validated in the test set with the specificity of 91.9% (83.1–97.0%) and sensitivity of 83.6% (72.5–91.6%). Sensitivities for stage I-III were 87.0% (79.7–92.4%) in the training set and 82.5% (70.2–91.3%) in the test set, respectively. In the unmatched total population, the positive ratios were 7.8% (5.2–11.2%) in healthy control, 30.8% (19.9–43.5%) in benign colorectal disease and 58.3% (27.5–84.7%) in advanced adenoma, while the sensitivities of stage I–IV were similar with training and test sets. Compared with methylated SEPT9 model, the present model had higher sensitivity (87.0% [81.8–91.2%] versus 41.2% [34.6–48.1%], P < 0.001) under comparable specificity (90.1% [85.4–93.7%] versus 90.6% [86.0–94.1%]). Conclusions Together our findings showed that ctDNA methylation markers were promising in the early detection of CRC. Further validation of this model is warranted in prospective studies.

Patients who are immunosuppressed either due to an underlying disease process or medications to treat a disease require important perioperative considerations. Preoperative evaluation mandates a higher index of suspicion for pathology given that peritoneal and systemic markers of illness may be masked. Intraoperatively, consideration should be given for diversion more frequently than in a nonimmunosuppressed patient. Postoperatively, patients should be managed in a multidisciplinary fashion. This review largely focuses on the immunosuppressive mediations used for the treatment of inflammatory bowel disease, benign colorectal disease in an immunosuppressed patient, and colorectal malignancies in immunosuppressed patients to highlight important considerations for this patient population. This review contains 4 figures, 5 tables, and 78 references. Key words: anal squamous cell carcinoma, appendicitis versus typhlitis, biologic therapy, corticosteroids, human papillomavirus, immunosuppression, neutropenic enterocolitis

Health literacy is the best predictor of health status, with patient information leaflets (PILs) commonly used to improve information access. However, they can often be inconsistent. Benign colorectal disease can be challenging for patients and ensuring they are accurate and understandable is important. Available PILs in a tertiary unit were assessed. The Flesch reading ease and Flesch-Kincaid Grade level scores were used to calculate objective readability. Subjective assessment of readability, understandability, and patient opinion was assessed using a questionnaire. All PILs had objective readability scores at age 14 or older, above recommended advice. Three hundred sixty patient questionnaires were collected. The relationship between subjective readability and understandability was significant ( P < .05); the easier a patient was able to read the information the more likely they were to understand it. There was no link between objective and subjective readability—a more difficult calculated reading score didn’t correspond to the patient finding it harder to read. Patients preferring paper information were significantly older than patients who preferred online information ( P = .01). Patient information leaflets remain valued by patients, and PILs that patients find easier to read are then better understood; however, ease of reading is not related to objective readability scoring and there was no consensus that a shift to online information is merited.
