Martius' flap for recurrent perineal and rectovaginal fistulae in a patient with Crohn's disease, endometriosis and a mullerian anomaly

Background: Rectovaginal fistulas represent 5% of all anorectal fistulae and are a disastrous manifestation of Crohn's disease that negatively affects patients' social and sexual quality of life. Treatment remains challenging for colorectal surgeons, and the recurrence rate remains high despite the numerous available options. Case presentation: We describe a 31-year-old female patient with a Crohn's disease-related recurrent perineo-vaginal and recto-vaginal fistulae and a concomitant mullerian anomaly. She complained of severe dyspareunia associated with penetration difficulties. The patient's medical history was also significant for a previous abdominal laparoscopic surgery for endometriosis for the removal of macroscopic nodules and a septate uterus with cervical duplication and a longitudinal vaginal septum. The patient was successfully treated using a Martius' flap. The postoperative outcome was uneventful, and no recurrence of the fistula occurred at the last follow-up, eight months from the closure of the ileostomy. Conclusion: Martius' flap was first described in 1928, and it is considered a good option in cases of rectovaginal fistulas in patients with Crohn's disease. The patient should be referred to a colorectal centre with expertise in this disease to increase the surgical success rate

Mesoglycan for pain control after open excisional HAEMOrrhoidectomy (MeHAEMO). An observational multicentre study on behalf of the Italian Society of Colorectal Surgery (SICCR)

Background: Excisional haemorrhoidectomy is the gold standard technique in patients with III and IV degree haemorrhoidal disease (HD). However, it is associated with a significant rate of post-operative pain. The aim of our study was to evaluate the efficacy of mesoglycan in the post-operative period of patients who underwent open excisional diathermy haemorrhoidectomy (OEH). Methods: This was a retrospective multicentre observational study. Three hundred ninety-eight patients from sixteen colorectal referral centres who underwent OEH for III and IV HD were enrolled. All patients were followed-up on the first post-operative day (T1) and after 1 week (T2), 3 weeks (T3) and 6 weeks (T4). BMI, habits, SF-12 questionnaire, VAS at rest (VASs), after defecation (VASd), and after anorectal digital examination (VASe), bleeding and thrombosis, time to surgical wound healing and autonomy were evaluated. Results: In the mesoglycan group, post-operative thrombosis was significantly reduced at T2 (p < 0.05) and T3 (p < 0.005), and all patients experienced less post-operative pain at each time point (p < 0.001 except for VASe T4 p = 0.003). There were no significant differences between the two groups regarding the time to surgical wound healing or post-operative bleeding. There was an early recovery of autonomy in the mesoglycan group in all three follow-up periods (T2 p = 0.016; T3 p = 0.002; T4 p = 0.007). Conclusions: The use of mesoglycan led to a significant reduction in post-operative thrombosis and pain with consequent early resumption of autonomy. Trial registration NCT0448169

Short-Term Outcomes of Polycarbophil and Propionibacterium acnes Lysate Gel after Open Hemorrhoidectomy. A Prospective Cohort Study

Background: Pain is the most common complication after open excisional hemorrhoidectomy (OEH). We assessed the effectiveness of polycarbophil and Propionibacterium acnes lysate gel (Emorsan(R)Gel) on pain control after OEH. Research design and methods: Fifty consecutive patients undergoing OEH were included. All patients received stool softeners and oral analgesia in the post-operative period. Emorsan(R)Gel was also used topically by the last 25 patients (Emorsan(R)Gel group (EG)) until Post-Operative Day 20 (POD 20). The primary outcome was the effectiveness of Emorsan(R)Gel on pain relief using an 11-point visual analogue scale (VAS). Morbidity, wound healing (WH), and time to work were documented at POD 1, POD 10, POD 20, and POD 40. Results: Of the 50 patients enrolled, twenty-eight (56%) were males; median age, 49 (range, 28-73) years. The VAS score decreased over time in all patients, with significantly lower scores at POD 20 in the EG (1.44 (SD, 1.16) vs. 2.12 (0.93) in the control group (CG); p = 0.045). All patients in the EG achieved complete WH at last follow-up, compared to only 17 (68%) in the CG (p = 0.004). The likelihood of WH was 66% higher in the EG (OR, 1.66 [95%CI, 0.80-3.44; p = 0.172). Conclusions: Emorsan(R)Gel is safe and effective at reducing pain after EOH, promoting earlier WH compared to standard care treatment

Altered Fecal Small RNA Profiles in Colorectal Cancer Reflect Gut Microbiome Composition in Stool Samples

Dysbiotic configurations of the human gut microbiota have been linked to colorectal cancer (CRC). Human small noncoding RNAs are also implicated in CRC, and recent findings suggest that their release in the gut lumen contributes to shape the gut microbiota. Bacterial small RNAs (bsRNAs) may also play a role in carcinogenesis, but their role has been less extensively explored. Here, we performed small RNA and shotgun sequencing on 80 stool specimens from patients with CRC or with adenomas and from healthy subjects collected in a cross-sectional study to evaluate their combined use as a predictive tool for disease detection. We observed considerable overlap and a correlation between metagenomic and bsRNA quantitative taxonomic profiles obtained from the two approaches. We identified a combined predictive signature composed of 32 features from human and microbial small RNAs and DNA-based microbiome able to accurately classify CRC samples separately from healthy and adenoma samples (area under the curve [AUC] = 0.87). In the present study, we report evidence that host-microbiome dysbiosis in CRC can also be observed by examination of altered small RNA stool profiles. Integrated analyses of the microbiome and small RNAs in the human stool may provide insights for designing more-accurate tools for diagnostic purposes.IMPORTANCE The characteristics of microbial small RNA transcription are largely unknown, while it is of primary importance for a better identification of molecules with functional activities in the gut niche under both healthy and disease conditions. By performing combined analyses of metagenomic and small RNA sequencing (sRNA-Seq) data, we characterized both the human and microbial small RNA contents of stool samples from healthy individuals and from patients with colorectal carcinoma or adenoma. With the integrative analyses of metagenomic and sRNA-Seq data, we identified a human and microbial small RNA signature which can be used to improve diagnosis of the disease. Our analysis of human and gut microbiome small RNA expression is relevant to generation of the first hypotheses about the potential molecular interactions occurring in the gut of CRC patients, and it can be the basis for further mechanistic studies and clinical test

A multicentre, open-label, single-arm phase II trial of the efficacy and safety of sclerotherapy using 3% polidocanol foam to treat second-degree haemorrhoids (SCLEROFOAM)

Background The aim of the present study was to evaluate the efficacy and safety of 3% polidocanol foam for treating 2nd-degree haemorrhoids. Methods A multicentre, open-label, single-arm, phase 2 trial involving 10 tertiary referral centres for haemorrhodal disease (HD) was performed. Between January and June 2019, patients with 2nd-degree haemorrhoids were prospectively included in this study. The primary outcome was to establish the success rate after one sclerotherapy session in terms of complete resolution of bleeding episodes one week after the injection. The Hemorrhoidal Disease Symptom Score (HDSS), the Short Health Scale for HD (SHS-HD) score and the Vaizey incontinence score were used to assess symptoms and their impact on quality of life and continence. Pain after the procedure, subjective symptoms and the amount and type of painkillers used were recorded. Patients were followed up for 1 year. Results There were 183 patients [111 males; 60.7%, mean age 51.3 +/- 13.5 (18-75) years]. Complete resolution of bleeding was reached in 125/183 patients (68.3%) at 1 week and the recurrence rate was 12% (15/125). Thirteen patients (7.4%) underwent a second sclerotherapy session, while only 1 patient (1.8%) had to undergo a third session. The overall 1-year success rate was 95.6% (175/183). The HDSS and the SHS score significantly improved from a median preoperative value of 11 and 18 to 0 and 0, respectively (p < 0.001). There were 3 episodes of external thrombosis. No serious adverse events occurred. Conclusions Sclerotherapy with 3% polidocanol foam is a safe, effective, painless, repeatable and low-cost procedure in patients with bleeding haemorrhoids. © 2022, The Author(s)

Sclerotherapy with 3% polidocanol foam to treat second-degree haemorrhoidal disease. Three-year follow-up of a multicentre, single arm, IDEAL phase 2b trial

Background Sclerotherapy with 3% polidocanol foam is becoming increasingly popular for the treatment of symptomatic I-II or III degree haemorrhoidal disease (HD). However, there are no studies that have reported a follow-up of more than 1 year. The purpose of this study was to analyse the long-term outcomes of sclerotherapy with 3% polidocanol foam in the treatment of II-degree HD. Methods This was an open label, single-arm, phase 2b trial conducted in 10 tertiary referral centres for HD. A total of 183 patients with II-degree HD, aged between 18 and 75 years with symptomatic HD according to the Goligher classification and unresponsive to medical treatment, were included in the study and underwent sclerotherapy with 3% polidocanol foam. The efficacy was evaluated in terms of bleeding score, haemorrhoidal disease symptom score (HDSS) and short health scale for HD (SHS-HD) score. Successful treatment was defined as the complete absence of bleeding episodes after 7 days (T1) according to the bleeding score. Results The overall success rate ranged from 95.6% (175/183) at 1 year to 90.2% (165/183) after the final 3 year follow-up. The recurrence rate, based on the primary outcome, ranged from 12% (15/125) to 28% (35/125). The greatest increase in recurrence (15) was recorded between 12 and 18 months of follow-up, then another five between 18 and 24 months. Both the HDSS and the SHS score remained statistically significant (p < 0.001) from a median preoperative value of 11 (10-13) and 18 (15-20) to 0 (0-2) and 4 (0-4), respectively. Symptom-free (HDSS = 0) patients, excluding patients converted to surgery, increased from 55.5% (101/182) at 1 year to 65.1% at 3 years (110/169). There were no intraoperative complications in redo-sclerotherapy nor additional adverse events (AEs) compared to the first 12 months. Conclusions Sclerotherapy with 3% polidocanol foam is gradually establishing itself in the treatment of bleeding HD due to its repeatability, safety, convenience in terms of direct and indirect costs with the absence of discomfort for the patient as well as AEs rather than an excellent overall success rate

Efficacy of Mesoglycan in Pain Control after Excisional Hemorrhoidectomy: A Pilot Comparative Prospective Multicenter Study

Introduction. Various pain management strategies for patients undergoing open excisional hemorrhoidectomy have been proposed, yet postoperative pain remains a frequent complaint. Objective. To determine whether mesoglycan (30 mg two vials i.m. once/day for the first 5 days postoperative, followed by 50 mg 1 oral tablet twice/day for 30 days) would reduce the edema of the mucocutaneous bridges and thus improve postoperative pain symptoms. Patients and Methods. For this prospective observational multicenter study, 101 patients undergoing excisional diathermy hemorrhoidectomy for III-IV degree hemorrhoidal disease were enrolled at 5 colorectal referral centers. Patients were assigned to receive either mesoglycan (study group SG) or a recommended oral dose of ketorolac tromethamine of 10 mg every 4–6 hours, not exceeding 40 mg per day and not exceeding 5 postoperative days according to the indications for short-term management of moderate/severe acute postoperative pain, plus stool softeners (control group CG). Results. Postoperative thrombosis (SG 1/48 versus CG 5/45) (p<0.001) and pain after rectal examination (p<0.001) were significantly reduced at 7–10 days after surgery in the mesoglycan-treated group, permitting a faster return to work (p<0.001); however, in the same group, the incidence of postoperative bleeding, considered relevant when needing a readmission or an unexpected outpatient visit, was higher, possibly owing to the drug’s antithrombotic properties. Conclusions. The administration of mesoglycan after an open diathermy excisional hemorrhoidectomy can reduce postoperative thrombosis and pain at 7–10 days after surgery, permitting a faster return to normal activities

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
