Review
Hemorrhoids are local vascular structure dilations in the lower rectum, associated with morbidity and reduced quality of life. Endovascular coil or particle embolization of the superior rectal arteries, known as Emborrhoid technique, is a minimally invasive, image-guided therapy that targets the hemorrhoidal plexus and reduces hemorrhage. The purpose of this review was to analyze the results of published studies to determine the efficacy, clinical outcomes, and morbidities associated with the endovascular occlusion of hemorrhoidal arteries for the treatment of internal hemorrhoids. Current evidences suggest that hemorrhoids treated by Emborrhoid technique using microcoils, embolic particles or a combination is safe with no reported serious complications. Hemorrhoid embolization can preserve the anal tone without direct anorectal trauma and maintain the hemorrhoidal tissue in place requiring minimal local wound care on an outpatient basis. However, due to the paucity of high-quality trials, further research is warranted to evaluate its long-term outcomes, compare its efficacy with other treatment modalities, and fully assess its role in the treatment of hemorrhoid.

Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up.

Review
INTRODUCTION
Haemorrhoids are cushions of submucosal vascular tissue located in the anal canal starting just distal to the dentate line. Incidence is difficult to ascertain as many people with the condition will never consult with a medical practitioner, although one study found 10 million people in the USA complaining of the disease.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for haemorrhoidal disease? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2008 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 44 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review we present information relating to the effectiveness and safety of the following interventions: closed haemorrhoidectomy, haemorrhoidal artery ligation, infrared coagulation/photocoagulation, injection sclerotherapy, open excisional (Milligan-Morgan/diathermy) haemorrhoidectomy, radiofrequency ablation, rubber band ligation, and stapled haemorrhoidectomy.

Colorectal cancer (CRC) is a common disease and one of the leading causes of cancer deaths worldwide. This retrospective cohort study evaluated the risk of developing CRC in people with hemorrhoids. Using Taiwan's National Health Insurance Research Database, we established three sets of retrospective study cohorts with and without hemorrhoids. The first set of cohorts were matched by sex and age, the second set of cohorts were matched by propensity score without including colonoscopies, and the third set of cohorts were matched by propensity score with colonoscopies, colorectal adenomas, and appendectomies included. In the second set of cohorts, 36,864 persons with hemorrhoids that were diagnosed from 2000 to 2010 and a comparison cohort, with the same size and matched by propensity score, were established and followed up to the end of 2011 to assess the incidence and Cox proportional regression-measured hazard ratio (HR) of CRC. The overall incidence rate of CRC was 2.39 times greater in the hemorrhoid cohort than it was in the comparison cohort (1.29 vs. 0.54 per 1000 person-years), with a multivariable model measured adjusted HR of 2.18 (95% CI = 1.78-2.67) after controlling for sex, age, and comorbidity. Further analysis on the CRC incidence rates among colorectal sites revealed higher incidence rates at the rectum and sigmoid than at other sites, with adjusted HRs 2.20 (95% CI = 1.48-3.28) and 1.79 (95% CI = 1.06-3.02), respectively. The overall incidence rates of both cohorts were similar in the first and second sets of cohorts, whereas the rate was lower in the third set of hemorrhoid cohorts than in the respective comparison cohorts, probably because of overmatching. Our findings suggest that patients with hemorrhoids were at an elevated risk of developing CRC. Colonoscopy may be strongly suggested for identifying CRC among those with hemorrhoids, especially if they have received a positive fecal occult blood test result.

Review
INTRODUCTION
Hemorrhoidal disease (HD) is characterized by prolapse of the inflamed and bleeding vascular tissues of the anal canal. Although HD is associated with a high recurrence rate, there is a lack of understanding around interventions that can reduce recurrence and improve outcomes for patients. As such, a systematic literature review (SLR) was conducted to summarize evidence on epidemiology, recurrence, and efficacy of interventions in HD.
METHODS
Real-world evidence (RWE) studies evaluating the incidence, prevalence, or recurrence of HD, as well as SLRs including a meta-analytic component reporting on the efficacy of systemic or topical pharmacological treatments for adults with HD, were included. Systematic searches were conducted in MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Database of Systematic Reviews.
RESULTS
The SLR identified 44 eligible publications. Consistent data were limited on the epidemiology of HD or HD recurrence. Specifically, incidence and prevalence reported across geographies were impacted by differences in data collection. Reported risk factors for HD were sedentary behavior, constipation, male gender, and age. Twenty-three RWE studies and one meta-analysis reported HD recurrence rates ranging from 0 to 56.5% following surgery or phlebotonics, with most (n = 19) reporting rates of 20% or less. In addition to time since treatment, risk factors for recurring disease were similar to those for HD in general. With respect to treatment, micronized purified flavonoid fractions significantly improved the main symptoms of HD compared to other pharmacological treatments.
CONCLUSION
The SLRs did not identify any RWE studies reporting recurrence in patients receiving systemic or topical treatments, highlighting the need for future research in this area. Further, more studies are needed to understand the optimum duration of medical treatment to prevent recurrence.

Comparative Study
AIM
To investigate the clinical significance of preoperative systemic immune-inflammation index (SII) in patients with colorectal cancer (CRC).
METHODS
A retrospective analysis of 1383 cases with CRC was performed following radical surgery. SII was calculated with the formula SII = (P × N)/L, where P, N, and L refer to peripheral platelet, neutrophil, and lymphocyte counts, respectively. The clinicopathological features and follow-up data were evaluated to compare SII with other systemic inflammation-based prognostic indices such as the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) in patients with CRC.
RESULTS
The optimal cut-off point for SII was defined as 340. The overall survival (OS) and disease-free survival (DFS) were better in patients with low NLR, PLR, and SII ( < 0.05). The SII was an independent predictor of OS and DFS in multivariate analysis. The area under the receiver-operating characteristics (ROC) curve for SII (0.707) was larger than those for NLR (0.602) and PLR (0.566). In contrast to NLR and PLR, SII could effectively discriminate between the TNM subgroups.
CONCLUSION
SII is a more powerful tool for predicting survival outcome in patients with CRC. It might assist the identification of high-risk patients among patients with the same TNM stage.

Observational Study
INTRODUCTION
This study was conducted to determine the frequency of complaints in a cohort of patients with symptomatic hemorrhoidal disease (HD) treated with micronized purified flavonoid fraction (MPFF, Detralex). MPFF was selected for conservative treatment in this population owing to its proven effects on hemorrhoidal symptoms in a large number of patients.
METHODS
This multicenter, non-interventional study was part of the international CHORUS survey (Chronic venous and HemORrhoidal diseases evalUation for improvement of Scientific knowledge), conducted in nine centers in different regions of Russia with the participation of 80 coloproctologists. The study enrolled consecutive patients with complaints of hemorrhoids. All were prescribed MPFF-based conservative treatment. The effect of treatment on HD clinical signs and symptoms was assessed at two follow-up visits performed 5-7 days and 25-30 days after enrollment. Surgical and minimally invasive treatment could be performed from day 7 onwards if required.
RESULTS
A total of 1952 patients were enrolled. Over the entire period of observation, MPFF-based conservative treatment was effective in 1489 (76.3%) patients in eliminating the main clinical manifestations of disease, i.e., bleeding and prolapse of internal nodes. Invasive treatment was performed in 68 (3.5%) patients with grade IV hemorrhoids and was combined with MPFF conservative treatment in 395 (20.2%) patients with grades I-III hemorrhoids.
CONCLUSION
Conservative therapy with MPFF was beneficial for relieving hemorrhoidal symptoms in the majority of patients. MPFF-based treatment was most effective in patients with grade I and II hemorrhoids before irreversible degenerative changes in ligaments of the hemorrhoidal plexuses have occurred. It was also beneficial in preventing disease relapse in patients with more advanced HD and for promoting optimal conditions in the postoperative period.

Meta-Analysis
INTRODUCTION
Hemorrhoidal disease (HD) is a common and recurrent problem for many adults worldwide. Venoactive drugs, such as micronized purified flavonoid fraction (MPFF; Daflon), have been used to treat HD and their clinical benefits have been demonstrated in previous meta-analyses of clinical trials. The aim of this study was to evaluate the efficacy of MPFF across the broader spectrum of signs and symptoms following treatment of patients with HD.
METHODS
We performed a systematic review of the literature to identify randomized clinical trials in which MPFF treatment was compared to placebo or no treatment for acute HD or for relief of symptoms after patients had undergone medical management or a surgical procedure to remove hemorrhoids. The main endpoints investigated were bleeding, pain, pruritus, discharge or leakage, and overall improvement. There was no limit on treatment duration.
RESULTS
From 351 unique records retrieved, 11 studies reported in 13 articles were included. On the basis of findings from qualitative analysis, MPFF was reported in most studies to be beneficial in treating bleeding, pain, pruritus, anal discharge/leakage, and tenesmus, and in overall improvement. Quantitative meta-analysis of four studies indicated that MPFF treatment provided significant benefits for bleeding (odds ratio [OR] 0.082, 95% confidence interval [CI] 0.027-0.250; P < 0.001), discharge/leakage (OR 0.12, 95% CI 0.04-0.42; P < 0.001), and overall improvement according to patients (OR 5.25, 95% CI 2.58-10.68; P < 0.001) and investigators (OR 5.51, 95% CI 2.76-11.0; P < 0.001). MPFF also tended to decrease pain (OR 0.11, 95% CI 0.01-1.11; P = 0.06).
CONCLUSION
Taken together, these results suggest that MPFF treatment can improve the most important signs and symptoms of HD.

Twenty cases of ischemic colitis are reviewed; 19 were obtained from autopsy files and the diagnosis in one was made from a surgical specimen. The majority of the patients were elderly with generalized arteriosclerosis. In approximately two-thirds of the patients the ischemic colitis was precipitated by preceding trauma, operation or congestive heart failure. Clinically, ischemic colitis is characterized by abdominal pain, distension and bleeding per rectum. Perforation of large bowel may occur. The lesions tend to be localized around the splenic flexure and junction of the descending and sigmoid colon, and in cases following aortic graft surgery the rectum is involved. Microscopically, there is necrosis, hemorrhage and ulceration. In less severe cases the mucosa only is affected. Cases with perforation show necrosis of all layers. It is considered that ischemic colitis is comparatively frequent and should be distinguished from other inflammatory conditions of the colon.

Comparative Study Meta-Analysis
BACKGROUND
Because conventional prostate biopsy has some limitations, optimal variations of prostate biopsy strategies have emerged to improve the diagnosis rate of prostate cancer. We conducted the systematic review to compare the diagnosis rate and complications of transperineal versus transrectal prostate biopsy. We searched for online publications published through June 27, 2018, in PubMed, Scopus, Web of Science, and Chinese National Knowledge Infrastructure databases. The relative risk and 95% confidence interval were utilized to appraise the diagnosis and complication rate. The condensed relative risk of 11 included studies indicated that transperineal prostate biopsy has the same diagnosis accuracy of transrectal prostate biopsy; however, a significantly lower risk of fever and rectal bleeding was reported for transperineal prostate biopsy. No clue of publication bias could be identified.
SHORT CONCLUSION
To conclude, this review indicated that transperineal and transrectal prostate biopsy have the same diagnosis accuracy, but the transperineal approach has a lower risk of fever and rectal bleeding. More studies are warranted to confirm these findings and discover a more effective diagnosis method for prostate cancer.
