Treatment of Hypertrophic Granulation Tissue: A Literature Review

Policresulen to treat hypergranulation tissue around drainage tubes

OBJECTIVE

To evaluate the efficacy of policresulen for the treatment of hypergranulation.

METHOD

This was a retrospective study of patients with percutaneous catheters. Inpatients from two hospitals and those from outpatient clinics were included. Approximately 2ml of 50% policresulen solution was applied to hypergranulation tissue, which was then immediately pressed with gauze for 1-3 minutes using light pressure. When haemostasis was achieved and the granulation tissue size decreased, the procedure was terminated.

RESULTS

A total of eight patients (four females and four males) were included in this study. Effective haemostasis was achieved in all patients. The size of the hypergranulation tissue decreased with policresulen treatment, and resolved completely in one patient. There were no complications. Hypergranulation tissue recurred in one patient. Haemostasis was successfully achieved after repeated procedures.

CONCLUSION

The findings of this study showed policresulen to be an inexpensive, easy treatment for hypergranulation at catheter insertion sites.

A Urologist's Guide to Caring for Transgender and Gender Diverse Patients

Urologists are experts in the fields of genital and pelvic anatomy, sexual health and reproductive medicine. As such, a working understanding of urologic conditions relevant to transgender and gender diverse patients should be expected within their scope of practice. Herein, we describe an introductory framework for general urologists to grow their knowledge of the appropriate terminology, anatomy, and basic tenets of gender-affirming care to better manage the urologic needs of transgender and gender diverse patients.

Patient reported symptoms and adverse outcomes seen in Canada's first vaginoplasty postoperative care clinic

IMPORTANCE

Vaginoplasty is a relatively common gender-affirming surgery with approximately 200 Ontarians seeking this surgery annually. Although Ontario now offers vaginoplasty in province, the capacity is not meeting demand; the majority of trans and gender-diverse patients continue to seek vaginoplasty out of province. Out-of-province surgery presents a barrier to accessing postsurgical follow-up care leaving most patients to seek support from their primary care providers or providers with little experience in gender-affirming surgery.

OBJECTIVE

To provide an account of the common postoperative care needs and neovaginal concerns of Ontarians who underwent penile inversion vaginoplasty out of province and presented for care at a gender-affirming surgery postoperative care clinic.

DESIGN, SETTINGS, AND PARTICIPANTS

A retrospective chart review of the first 80 patients presenting to a gender-affirming surgery postoperative care clinic who had undergone vaginoplasty at an outside surgical center was performed. Descriptive analyses were performed for all variables.

RESULTS

The sample consisted of 80 individuals with the mean age of 39 years (19-73). Most patients had surgery at another surgical center in Canada (76.3%). Many patients (22.5%) accessed care in the first 3 months after surgery, with the majority (55%) seeking care within the first perioperative year. Most patients (61.3%) were seen for more than one visit and presented with more than two symptoms or concerns. Common patient-reported symptoms during clinical visit included pain (53.8%), dilation concerns (46.3%), and surgical site/vaginal bleeding (42.5%). Sexual function concerns were also common (33.8%) with anorgasmia (11.3%) and dyspareunia (11.3%) being the most frequent complications. The most common adverse outcomes identified by health care providers included hypergranulation (38.8%), urinary dysfunction (18.8%), and wound healing issues (12.5%).

CONCLUSIONS AND RELEVANCE

Findings from chart review offer valuable insights into the postoperative needs and neovaginal concerns of Ontarians who have had vaginoplasty out of province. This study demonstrates the need for routine postoperative care in patients undergoing vaginoplasty. Patients experience numerous symptoms and concerns that often correlate with clinical findings and require multiple follow-up appointments. Health care providers may benefit from further education on the more common nonsurgical issues identified in this study.

Hypertrophic granulation wounds treated with silver nitrate sticks or with topical steroid: Rate of wound closure

Hypertrophic granulation (HG) is abnormal granulation tissue raised above the level of surrounding intact skin, and is thought to delay wound healing. Effective treatment to eliminate HG could speed healing, but this is not well studied. Two common treatments are chemical cautery with silver nitrate, and use of topical steroid. In a Midwestern burn and wound clinic, both of these treatments are employed. A quality improvement project compared wound size reduction for HG wounds undergoing the two treatment modalities. Retrospective chart review identified HG wounds treated during a one-year period, and compared wound size prior to and after one month of treatment (length, width and surface area). Results were presented to the clinic staff, and one year later the quality assurance project was repeated. The initial audit found data on 18 patients treated with silver nitrate cautery, and 16 patients treated with 1% hydrocortisone cream. Median length and width was decreased by 5 mm with silver nitrate cautery treatment, and by 14 mm with 1% hydrocortisone treatment (p<.05). The repeat audit one year later found 10 patients treated with silver nitrate, and 38 treated with hydrocortisone. Median length and width decreased by 0 and 2 mm respectively for silver nitrate cautery treatment, and 15 and 10 mm for 1% hydrocortisone treatment (p<.05). In conclusion, this uncontrolled review suggests faster healing in HG wounds treated with 1% hydrocortisone compared with those treated with silver nitrate cautery. Confirmation with controlled and randomized studies is warranted.

Gender-Affirming Surgeries in Transgender and Gender Diverse Adolescent and Young Adults: A Pediatric and Adolescent Gynecology Primer

Transgender and gender diverse adolescent and young adults (AYA) may seek gender-affirming surgeries (GAS) as part of their gender affirmation. A number of GAS are related to reproductive and sexual health, and pediatric and adolescent gynecology (PAG) clinicians are well positioned as sexual and reproductive health experts to provide care in this area. PAG clinicians may encounter patients presenting for preoperative counseling (including discussions regarding fertility, family building, future sexual function, and choice of oophorectomy at time of hysterectomy), requesting referrals to GAS clinicians, or requiring GAS aftercare, or those seeking general sexual and reproductive health care who have a history of GAS. This article reviews presurgical considerations for AYA seeking GAS, types of GAS, their impact on pelvic, sexual, and reproductive health, and aftercare that may involve PAG providers, with the goal of helping PAG clinicians to better understand these procedures and to empower them to engage collaboratively with GAS teams. With this knowledge, reproductive health clinicians can have an integral role as skilled collaborators in the world of AYA GAS in partnership with GAS surgeons.

The gynecologic examination of the transfeminine person after penile inversion vaginoplasty

As more transfeminine patients (transgender and gender-diverse persons, sex assigned male at birth, who identify on the feminine spectrum of gender) are undergoing gender-affirming penile inversion vaginoplasty, gynecologists, as providers of vaginal care for both native and neovaginas, should be prepared to welcome these patients into their practice and offer long-term pelvic healthcare. Many parts of the anatomy, clinical examination, and aftercare differ from both native vaginas and other neovaginal surgical techniques. Transgender and gender-diverse patients cite a lack of clinician knowledge as a barrier to accessing affirming and competent healthcare. Although publications are emerging regarding this procedure, most focus on intraoperative and postoperative complications. These studies are not positioned to provide long-term pelvic health guidance or robust instruction on typical examination findings. This clinical opinion aims to address that knowledge gap by describing the gynecologic examination in the transfeminine person who has undergone a penile inversion vaginoplasty. We review the anatomic changes with surgery and the neovagina's physiology. We describe the examination of the vulva, vagina, and urethra and discuss special considerations for performing pelvic examinations on patients with a penile inversion vaginoplasty neovagina. We will also address common pathologic findings and their initial management. This clinical opinion originates from the expertise of gynecologists who have cared for high volumes of transfeminine patients who have undergone penile inversion vaginoplasties at tertiary care centers performing gender-affirming genital surgery, along with existing research on postpenile inversion vaginoplasty outcomes. Gynecologists should be familiar with the anatomic changes that occur with penile inversion vaginoplasty gender-affirming surgery and how those changes affect care. Providing transgender patients with comprehensive care including this sensitive examination can and should be part of the gynecologist's scope of practice.

Evaluation of a polyurethane-reinforced hydrogel patch in a rat right ventricle wall replacement model

Congenital heart defects affect about 1% births in the United States. Many of the defects are treated with surgically implanted patches made from inactive materials or fixed pericardium that do not grow with the patients, leading to an increased risk of arrhythmia, sudden cardiac death, and heart failure. This study investigated an angiogenic poly(ethylene glycol) fibrin-based hydrogel reinforced with an electrospun biodegradable poly(ether ester urethane) urea (BPUR) mesh layer that was designed to encourage cell invasion, angiogenesis, and regenerative remodeling in the repair of an artificial defect created onto the rat right ventricle wall. Electrocardiogram signals were analyzed, heart function was measured, and fibrosis, macrophage infiltration, muscularization, vascularization, and defect size were evaluated at 4- and 8-weeks post-surgery. Compared with rats with fixed pericardium patches, rats with BPUR-reinforced hydrogel patches had fewer arrhythmias and greater right ventricular ejection fraction and cardiac output, as well as greater left ventricular ejection fraction, fractional shorting, stroke work and cardiac output. Histology and immunofluorescence staining showed less fibrosis and less patch material remaining in rats with BPUR-reinforced hydrogel patches at 4- and 8-weeks. Rats with BPUR-reinforced hydrogel patches also had a greater volume of granular tissue, a greater volume of muscularized tissue, more blood vessels, and a greater number of leukocytes, pan-macrophages, and M2 macrophages at 8 weeks. Overall, this study demonstrated that the engineered BPUR-reinforced hydrogel patch initiated greater regenerative vascular and muscular remodeling with a limited fibrotic response, resulting in fewer incidences of arrhythmia and improved heart function compared with fixed pericardium patches when applied to heal the defects created on the rat right ventricle wall. STATEMENT OF SIGNIFICANCE: The study tested a polyurethane-reinforced hydrogel patch in a rat right ventricle wall replacement model. Compared with fixed pericardium patches, these reinforced hydrogel patches initiated greater regenerative vascular and muscular remodeling with a reduced fibrotic response, resulting in fewer incidences of arrhythmia and improved heart function at 4- and 8-weeks post surgery. Overall, the new BPUR-reinforced hydrogel patches resulted in better heart function when replacing contractile myocardium than fixed pericardium patches.
