Background: Implantation of the amniotic membrane and their derivatives can have a beneficial effect on tissue repair and regeneration. We report for the first time the implant of an amniotic membrane in a patient affected by cryptoglandular anal fistula. Methods: A patch of human amniotic membrane was implanted in a female patient affected by an anterior transphincteric fistula. Following an accurate curettage of the anal fistula, the cryopreserved amniotic membrane was thawed and then washed in the operating room; one side of the membrane was transfixed with a resorbable suture thus creating an implantable fusiform patch. The membrane was subsequently implanted into the fistula tract from the external to the internal opening. The inner and outer parts of the membrane were then sutured to the internal and external fistula openings. Results: No intraoperative or postoperative complications occurred. The patient was discharged one day after the procedure after an uneventful hospitalization. At the 1-week, 1- and 3-month follow-up visits no pain (VAS 0) was referred by the patient and no inflammation was evident at the level of the previous external fistula opening. Conclusions: The implant of human amniotic membrane in a patient affected by cryptoglandular anal fistula was safely and easily performed. Moreover, future studies to assess the efficacy in the long-term follow-up are needed.

Background: Arterial hyperflow to haemorrhoids has been implicated as a possible pathophysiological co-factor in haemorrhoidal disease. The purpose of this study was to investigate how transanal haemorrhoidal dearterialization (THD) can influence haemodynamic parameters at the level of the haemorrhoidal piles. Methods: Patients with grade III haemorrhoids selected for THD between July and December 2018 were evaluated using endoanal ultrasonography and colour Doppler imaging at the level of internal haemorrhoids before and 1 year after the surgical procedure. Peak systolic velocity, pulsatility index, resistivity index, acceleration time, and end-diastolic velocity were measured, and preoperative and postoperative values compared. Symptom severity was measured using a symptom-based questionnaire (score range 0–20). Results: Of 21 patients treated, 17 completed the study. Compared with preoperative values, postoperative peak systolic velocity (mean(s.d.) 18.7(1.1) versus 10.3(0.4) cm/s; P < 0.05), pulsatility index (5.5(0.3) versus 2.8(0.4); P < 0.050), and resistivity index (1.0(0.2) versus 0.8(0.5); P < 0.050) decreased significantly, whereas acceleration time increased significantly (65.6(3.6) versus 83.3(4.7) cm/s2; P < 0.050); end-diastolic velocity did not change (1.9(0.2) versus 2.0(0.4); P = 0.753). Symptoms disappeared or had improved significantly in all patients by 1 year after surgery. The mean(s.d.) total symptom severity score decreased from 15.8(1.1) to 1.2(1.6) (P < 0.001). Conclusion: THD affects the main haemodynamic parameters at the level of internal haemorrhoids and is associated with a decrease in arterial hyperflow.

The Emborrhoid is an innovative non-surgical technique for the treatment of severe hemorrhoidal bleeding. Patient selection and the impact on quality of life have not been fully investigated. This prospective observational study aims to evaluate the clinical outcomes after Emborrhoid in patients with high surgical risk. All patients with high surgical risk and anemia due to hemorrhoids were enrolled. Clinical data and previous blood transfusions were collected. The Hemorrhoidal Disease Symptom Score and Short Health Scala were completed before the procedure and during the follow-up visits at 1, 6 and 12 months. Transfusions and serum hemoglobin level variations were registered. Perioperative complications and the recurrence of bleeding were assessed. Trans-radial/femoral embolization of superior rectal artery, and/or middle rectal artery was performed with Interlock and Detachable Embolization Coils. From September 2020 to February 2022, 21 patients underwent a superselective embolization of all branches of the superior rectal artery. The transradial approach was most frequently performed compared to transfemoral access. After the procedure, no signs of ischemia were identified; three minor complications were observed. The mean follow-up was 18.5 ± 6.0 months. At the last follow-up, the mean increase of hemoglobin for patients was 1.2 ± 1.6 g/dL. Three patients needed transfusions during follow-up for recurrent hemorrhoidal bleeding. The Hemorrhoidal Disease Symptom Score and Short Health Scala decreased from 11.1 ± 4.2 to 4.7 ± 4.6 (p < 0.0001) and from 18.8 ± 4.8 to 10.2 ± 4.9 (p < 0.0001), respectively. Patients who had given up on their daily activities due to anemia have returned to their previous lifestyle. Emborrhoid seems to be a safe and effective option for the treatment of bleeding hemorrhoids in frail patients. The low complication rate and the significant reduction of post-defecation bleeding episodes are related to the improvement of the hemorrhoidal symptoms and patients’ quality of life.

The aims of this study were to evaluate the efficacy of two different phlebotonic therapies, preoperatively administered in advanced hemorrhoidal disease (HD) patients with recommendation for surgery, and to assess patient satisfaction after treatment. In this prospective observational study, 100 patients were preoperatively treated either with micronized purified flavonoid fraction (group A) or sublingual nano-emulsion flavonoid (group B). HD symptoms, local inflammation signs and patients’ satisfaction were evaluated at baseline visit (T0), after 4 weeks of therapy (T1) and 8 weeks after its discontinuation (T2). In group A, a significant improvement for all HD symptoms and inflammation signs was observed after therapy (T1), followed by a reduction of efficacy in T2, except for itching and edema. In group B, therapy had a significant benefit on symptoms and local inflammation at T1, which persisted after its discontinuation for all symptoms, and edematous hemorrhoids. In both groups, the satisfaction rate was “good” in 60% of patients and patients were statistically significant more satisfied at T1 compared with T2 (p = 0.0001). No adverse events were recorded. Preoperative treatment was safe and useful to optimize patients’ clinical condition prior to surgery.

The aims of this population study were to assess the lockdown impact on patients waiting for hemorrhoidal surgery, and the role of telemedicine in patient management. All patients on our waiting list for hemorrhoidal surgery were considered. Eligible patients were contacted by phone. Rørvik score was evaluated and compared to the baseline score. Univariate and multivariate analyses were performed. A numeric rating scale was used to estimate patient satisfaction regarding telemedicine. One-hundred and ten patients were found to be eligible. Finally, 103 patients were included in the study of whom 16 (15.3%) were already considered for priority surgery. Patients waiting for a longer time showed significantly worse scores (p < 0.001). After telemedicine evaluation the priority waiting list increased by 43.8% (plus 23 patients). Weight loss of at least 3 kg and physical activity were found to be protective factors (p = 0.02 and p = 0.002 respectively). A high grade of satisfaction (almost 80%) towards telemedicine was registered. COVID-19-related delays are linked to a deterioration of hemorrhoidal symptoms and patients’ well-being. Weight and lifestyle changes were deemed key factors in determining disease severity. Telemedicine was a valuable tool to evaluate and re-evaluate patients waiting for hemorrhoidal surgery and was considered satisfactory by patients.
