D.A., male, 21 years old, MRI. All patients, except 1 with hemorrhage from the perianal surgical wound conservatively resolved with suture placement, were discharged the day after the procedure. Perianal fistulas are categorized as “complex” under the following conditions: a high tract passing the upper two-thirds of the external sphincter, presence of multiple fistula tracts, rectovaginal fistulas, previous local irradiation, and association with the presence of an anorectal stricture or Crohn׳s disease.

In this review we will address the anatomy, pathogenesis, classification and scanning protocol of perianal fistulas. The fat was then harvested (50 to 100 cc) using a 13G blunt cannula connected to a 20-mL VacLok syringe.The harvested fat was immediately processed in the Lipogems processing kit (Lipogems International Spa, Milan, Italy) as previously described.The Lipogems system operative scheme. This represents a costly and time-consuming approach that causes limitations in daily clinical practice. This culminated into the concept of a collaborative multidisciplinary approach using the latest medical therapies combined with modern surgical and endoscopic techniques. The device consists of (1) a processing unit which contains 5 stainless steel balls, an input sieve; (2) an output sieve; (3) (4) a saline input line, connected to the blue side of the processing unit; an access port with luer‐lock connection; (5) a self‐occluding valve (6) at blue side to load the lipoaspirate; (7) a drainage line connected to the gray side of the processing unit; (8) an access port with luer-lock connection and (9) self-occluding valve to unload processed material; and (10) a collection bag for waste fluid.

Orsola-Malpighi Hospital, Via Massarenti 9, Bologna, Italy. Perianal fistula (or fistula-in-ano) (plural: fistulae or fistulas) is the presence of a fistulous tract across/between/adjacent to the anal sphincters and is usually an inflammatory condition 4.
Sometimes, they get blocked or clogged. The routine employment of this technique could have major implications in those patients where recurrent, refractory and complex perianal fistulas usually require repeated surgery with the risk of sphincteric damage and fecal incontinence and, eventually, the subsequent need of proctectomy and permanent oostomy. The processing unit, filled with normal saline solution, is maintained in flow condition by gravity. After saline priming, adipose tissue inserted in the device undergoes a first reduction and micronization of the lipid clusters by means of the input sieve.
Sometimes they close on their own, then open back up. Published by Elsevier Ltd. All rights reserved.ScienceDirect ® is a registered trademark of Elsevier B.V. Due to the small sample size, it was not possible to identify any factor associated with an unsuccessful outcome. Complex perianal fistulas represent one of the most challenging manifestations of Crohn’s disease. For statistical comparisons, the The study was approved by the Ethics Committee of S. Orsola-Malpighi Hospital (protocol Lipogems-crohn2, number 4/2016/U/Sper, January 19, 2016). Only minor complications relating to the lipoaspiration procedure were recorded. Anal pain and discomfort are unfavorable factors compromising the quality of life, and self-reported depressive symptoms are frequently concomitantly observed, underlining the negative impact on quality of life.Finally, yet of no less importance, there were no side effects related to adipose tissue harvesting and injection and/or surgical treatment. Multi-“-Omics” Profiling in Patients With Quiescent Inflammatory Bowel Disease Identifies Biomarkers Predicting Relapse Black bars are combined remission patients; gray bars are noncombined remission patients.Neither intra- nor postoperative major complications occurred. Before the harvesting, the donor site was injected with 100 cc of Klein Solution (500 cc saline, 1 cc epinephrine 1/1000 IU, and 40 cc lidocaine 2%) using a disposable 17G blunt cannula connected to a 60-cc luer-lock syringe. Preoperative MR can help to prevent recurrence. (A, B) and digital photograph (C, D) of the external fistula orifice. (A, B) and digital photograph (C, D) of the external fistula orifice. Thus the gastroenterologist and surgeon have to be familiar with several approaches and/or techniques. We recorded only minor bleeding from the surgical wound within 12 hours post-op in 1 patient, which needed sutures placement.This is certainly only a preliminary experience dealing with a small number of patients without a control group.

Recently, new therapeutic approaches, such as the use of mesenchymal stromal cells, have shown promising results. Moreover, the use of ASCs implies complex restrictions related to cell expansion and extensive manipulation.The occurrence of treatment-related abscesses, due to a “false” closure of the fistula tract, is a concern among patients with PCD receiving short- or long-term infliximab treatment, when the definition of “fistula healing” is based only on the clinical examination and defined as “absence of drainage upon gentle finger compression at the external orifice;” recurrences were reported in 12%The fact that no patient reported treatment-related abscesses is important and confirms the effectiveness of the combination of surgical drainage with fistulectomy and the regenerative therapy approach.
