The Centers for Disease Control and Prevention sponsored a project conducted by the American College of Obstetricians and Gynecologists to develop educational materials for clinicians on the prevention and early diagnosis of gynecologic cancers. For this final module, focusing on the cancers of the lower anogenital tract (vulva, vagina, and anus), a panel of experts in evidence assessment from the Society for Academic Specialists in General Obstetrics and Gynecology, ASCCP, and the Society of Gynecologic Oncology reviewed relevant literature and current guidelines. Panel members conducted structured literature reviews, which were then reviewed by other panel members. Representatives from stakeholder professional and patient advocacy organizations met virtually in September 2022 to review and provide comment. This article is the executive summary of the review. It covers prevention, early diagnosis, and special considerations of lower anogenital tract cancer. Knowledge gaps are summarized to provide guidance for future research.

Review
Anal and rectal cancers were some of the first disease sites treated with brachytherapy due to the anatomic ease of implantation. As external beam radiotherapy grew in popularity the use of ano-rectal brachytherapy declined. However, the past few years have seen a steady resurgence in the use of brachytherapy in the ano-rectum supported by the use of large clinical series and randomized trials. The increasing acceptance by the surgical community of organ preservation as a valid treatment strategy for rectal cancer has encouraged the use of nonsurgical approaches and brachytherapy has shown itself to be a valuable tool for this. The current role of anal and rectal brachytherapy is presented with perspectives on its future use.

BACKGROUND
In the United States, anal squamous cell carcinoma rates have increased rapidly, particularly among women 50 or older than 66 years of age. As immunosuppression is associated with increased risk, autoimmune conditions may be associated with greater risk of anal squamous cell carcinoma.
METHODS
We conducted a population-based, case-control study using Surveillance, Epidemiology, and End Results-Medicare data (2000-2017). Anal squamous cell carcinoma cases (n = 4505) were matched to 200 000 cancer-free controls. Using multivariable logistic regression, we calculated odds ratios (ORs) and 95% confidence intervals (CIs) for associations between 47 autoimmune conditions diagnosed before selection, identified using Medicare claims, and anal squamous cell carcinoma. The Bonferroni threshold was used to correct for multiple comparisons. Population attributable fractions were calculated for conditions nominally associated with anal squamous cell carcinoma.
RESULTS
In total, 18% of anal squamous cell carcinoma cases and 15% of cancer-free controls had a diagnosed autoimmune condition. Any autoimmune condition was associated with an increased risk of anal squamous cell carcinoma (OR = 1.11, 95% CI = 1.02 to 1.21; population attributable fraction = 1.8%). Anal squamous cell carcinoma was associated with systemic lupus erythematosus (OR = 1.79, 95% CI = 1.32 to 2.42; population attributable fraction = 0.4%) and nominally associated (P < .05) with sarcoidosis (OR = 2.09, 95% CI = 1.30 to 3.37; population-attributable fraction = 0.2%) and psoriasis (OR = 1.28, 95% CI = 1.06 to 1.56; population attributable fraction = 0.5%). Stratified by sex, only women showed statistically significant associations for systemic lupus erythematosus (OR = 1.97, 95% CI = 1.46 to 2.68). Statistically significant interaction was observed by sex for psoriasis (men vs women: OR = 1.68 [95% CI = 1.03 to 4.28] vs OR = 1.12 [95% CI = 0.88 to 1.43]) and polymyalgia rheumatica (OR = 0.33 [95% CI = 0.12 to 0.89] vs OR = 0.99 [95% CI = 0.75 to 1.30]).
CONCLUSION
Systemic lupus erythematosus, sarcoidosis, and psoriasis were associated with a moderately increased risk of anal squamous cell carcinoma. Given these conditions' rarity and moderate associations with anal squamous cell carcinoma, autoimmune diseases cannot explain the rising trend in this disease.

INTRODUCTION
Many pouch complications following ileoanal pouch surgery have an inflammatory or mechanical nature, and specialist colorectal surgeons are required to assess the anatomy of the ileoanal pouch in multiple settings. In this study, we report our stepwise clinical and endoscopic assessment of the patient with an ileoanal pouch.
METHODS
The most common configuration of the ileoanal pouch is a J-pouch, and the stapled anastomosis is more frequently performed than a handsewn post-mucosectomy. A structured clinical and endoscopic assessment of the ileoanal pouch must provide information on 7 critical areas: anus and perineum, rectal cuff, pouch anal anastomosis, pouch body, blind end of the pouch, pouch inlet and pre-pouch ileum.
RESULTS
We have developed a structured pro forma for step-wise assessment of the ileoanal pouch, according to 7 essential areas to be evaluated, biopsied and reported. The structured assessment of the ileoanal pouch in 102 patients allowed reporting of abnormal findings in 63 (61.7%). Strictures were diagnosed in 27 patients (26.4%), 3 pouch inlet strictures, 21 pouch anal anastomosis strictures, and 3 pre-pouch ileum strictures. Chronic, recurrent pouchitis was diagnosed in 9 patients, whilst 1 patient had Crohn's disease of the pouch.
CONCLUSIONS
Detailed clinical history, assessment of symptoms and multidisciplinary input are all essential for the care of patients with an ileoanal pouch. We present a comprehensive reporting pro forma for initial clinical assessment of the patient with an ileoanal pouch, with the aim to guide further investigations and inform multidisciplinary decision-making.

Randomized Controlled Trial
Sexual minority men are at increased risk for anal squamous cell carcinoma. Our objective was to compare screening engagement among individuals randomized to self-collect an anal canal specimen at home or to attend a clinic appointment. Specimen adequacy was then assessed for human papillomavirus (HPV) DNA genotyping. A randomized trial recruited cisgendered sexual minority men and transgender people in the community and assigned them to use a home-based self-collection swabbing kit or attend a clinic-based swabbing. Swabs were sent for HPV genotyping. The proportions of participants completing screening in each study arm and the adequacy of their specimens for HPV genotyping were assessed. Relative risks were estimated for factors associated with screening. A total of 240 individuals were randomized. Age (median, 46 years) and HIV status (27.1% living with HIV) did not differ by study arm. A total of 89.2% and 74.2% of home-arm and clinic-arm individuals returned the swab, respectively (P = .003), difference between groups, 15.0% (95% CI 5.4%-24.6%). Among black individuals, 96.2% and 63.2% in the home and clinic arms screened (P = .006). Among individuals with HIV, 89.5% and 51.9% in the home and clinic arms screened (P < .001). Self-collected swabs and clinician-collected swabs were comparable in adequacy for HPV genotyping (96.3% and 93.3%, respectively). People at highest risk for anal cancer may be more likely to screen if they are able to self-collect swabs at home rather than attend a clinic.

Review
PURPOSE OF REVIEW
Early detection and treatment of human papillomavirus (HPV)-related anal dysplasia in some high-risk groups can help anal cancer prevention, but new tools to improve diagnostic and risk assessment are needed. Here, we aim to discuss the evidence on the role of the microbiome as a potential biomarker for anal high-grade squamous intraepithelial lesions (HSILs) in people with HIV (PWH).
RECENT FINDINGS
This review covers relevant studies on the links between the microbiome and HPV infection, cervical dysplasia/cancer, and anal HPV disease. It focuses on anal samples and precancerous lesions.
SUMMARY
The review highlights the promising potential of the anal microbiome as a novel biomarker for precancerous lesions in people with HIV, while also discussing limitations and future research needs.

In 2000, the small bowel capsule revolutionized the management of patients with small bowel disorders. Currently, the technological development achieved by the new models of double-headed endoscopic capsules, as miniaturized devices to evaluate the small bowel and colon [pan-intestinal capsule endoscopy (PCE)], makes this non-invasive procedure a disruptive concept for the management of patients with digestive disorders. This technology is expected to identify which patients will require conventional invasive endoscopic procedures (colonoscopy or balloon-assisted enteroscopy), based on the lesions detected by the capsule, those with an indication for biopsies or endoscopic treatment. The use of PCE in patients with inflammatory bowel diseases, namely Crohn's disease, as well as in patients with iron deficiency anaemia and/or overt gastrointestinal (GI) bleeding, after a non-diagnostic upper endoscopy (esophagogastroduodenoscopy), enables an effective, safe and comfortable way to identify patients with relevant lesions, who should undergo subsequent invasive endoscopic procedures. The recent development of magnetically controlled capsule endoscopy to evaluate the upper GI tract, is a further step towards the possibility of an entirely non-invasive assessment of all the segments of the digestive tract, from mouth-to-anus, meeting the expectations of the early developers of capsule endoscopy.

Review
The role and method of image-based staging of anal cancer has evolved with the rapid development of newer imaging modalities and the need to address the rising incidence of this rare cancer. In 2014, the European Society of Medical Oncology mandated pelvic magnetic resonance imaging (MRI) for anal cancer and subsequently other societies such as the National Comprehensive Cancer Network followed suit with similar recommendations. Nevertheless, great variability exists from center to center and even within individual centers. Notably, this is in stark contrast to the imaging of the anatomically nearby rectal cancer. As participating team members for this malignancy, we embarked on a comprehensive literature review of anal cancer imaging to understand the relative merits of these new technologies which developed after computed tomography (CT), e.g., MRI and positron emission tomography/computed tomography (PET/CT). The results of this literature review helped to inform our next stage: questionnaire development regarding the imaging of anal cancer. Next, we distributed the questionnaire to members of the Society of Abdominal Radiology (SAR) Rectal and Anal Disease-Focused Panel, a group of abdominal radiologists with special interest, experience, and expertise in rectal and anal cancer, to provide expert radiologist opinion on the appropriate anal cancer imaging strategy. In our expert opinion survey, experts advocated the use of MRI in general (65% overall and 91-100% for primary staging clinical scenarios) and acknowledged the superiority of PET/CT for nodal assessment (52-56% agreement for using PET/CT in primary staging clinical scenarios compared to 30% for using MRI). We therefore support the use of MRI and PET and suggest further exploration of PET/MRI as an optimal combined evaluation. Our questionnaire responses emphasized the heterogeneity in imaging practice as performed at numerous academic cancer centers across the United States and underscore the need for further reconciliation and establishment of best imaging practice guidelines for optimized patient care in anal cancer.

BACKGROUNDS
Appendicitis (AP) is a prevalent and sudden disease, and although surgery can be effective in treating it, post-surgical care is of great importance in improving the patient's recovery.
OBJECTIVE
To analyze the impact of Failure Mode and Effect Analysis (FMEA)-based nursing on patients with AP after surgery.
METHODS
A total of 104 patients with AP who received treatment in Fuyang Shi Hospital of TCM from December 2021 to February 2023 were enrolled and randomly divided into a control group (n = 52) who received routine nursing and a research group (n = 52) who receive FMEA-based nursing. The time to recovery of bowel sounds, time to defecation by anus, time to anal exhaust, and length of stay were statistically analyzed in both groups after surgery. Pain, sleep, and psychological status of patients before and after surgery were assessed using the visual analog scale (VAS), Pittsburgh Sleep Quality Index (PSQI), and self-rating anxiety scale/self-rating depression scale (SAS/SDS). Patients' satisfaction with nursing was also investigated, and the incidence of postoperative complications was recorded.
RESULTS
After surgery, the research group showed shorter time to recovery of bowel sounds, time to defecation by anus, time to anal exhaust, and length of stay, and lower scores of VAS, PSQI, SAS, and SDS than those of the control group (P < .05). As indicated by the satisfaction survey, compared with the control group, the research group showed a larger number of patients who were very satisfied with nursing and a smaller number of patients who thought their nursing should be improved; the incidence of postoperative complications was also lower in the research group (P < .05).
CONCLUSION
For patients with AP, FMEA-based nursing improves their postoperative recovery, alleviates their pain, and ameliorates their sleep quality, which is of high clinical application value.
