A New Perspective on Vacuum-Assisted Closure for the Treatment of Anastomotic Leak Following Low Anterior Resection for Rectal Cancer, Is It Worthy?

Background: Anastomotic dehiscence is a common complication of anterior resection. In this work, we evaluate the management of the pelvic cavity after low rectal resection using vacuum closure (VAC) with a gastroscope, and we establish factors that determine the success of closure and analyzed the rate of ileostomy closure after leakage was resolved.

Patients And Methods: This is a descriptive case series analysis conducted at a tertiary hospital.

Fecal incontinence in older patients. A narrative review.

Fecal incontinence is one of the leading causes for the institutionalization of people in the last decades of life, associated with a great psychosocial and economic burden. The literature is scarce in this population group, due to the absence of universally accepted criteria to define "elderly patients" and difficulties in detection and diagnostic. The aim of this article was to conduct a narrative review of the main aspects related to fecal incontinence in older patients, providing management support.

Treatment of transsphincteric fistula-in-ano with growth factors from autologous platelets: results of a phase II clinical trial.

Purpose: The aim of this paper is to evaluate to the safety, feasibility and efficacy of a novel treatment for transsphincteric cryptoglandular fistula: injection of autologous plasma rich in growth factors (PRGF) into the fistula tract accompanied by sealing using a fibrin plug created from the activated platelet-poor fraction of the same plasma.

Method: This article is a prospective, phase II clinical trial. The procedure was externally audited.

Factibility and security study of the PICS-AF™ plug for the treatment of cryptoglandular anal fistula.

Introduction: The PICS-AF™ (Curaseal Inc.) device is a new plug made of collagen that has a retention system in the internal orifice. This pilot study was designed to assess both the feasibility and safety of this plug in the treatment of trans-sphincteric anal fístulas.

Ultrasonographic evidence of Gatekeeper™ prosthesis migration in patients treated for faecal incontinence: a case series.

Background: Faecal incontinence (FI) is both a medical and social problem, with an underestimated incidence. For patients with internal anal sphincter damage, implantation of biomaterial in the anal canal is a recognised treatment option. One such material, Gatekeeper™, has previously shown promising short- and medium-term results without any major complications, including displacement.

Learning curve in robotic rectal cancer surgery: current state of affairs.

Introduction: Robotic-assisted rectal cancer surgery offers multiple advantages for surgeons, and it seems to yield the same clinical outcomes as regards the short-time follow-up of patients compared to conventional laparoscopy. This surgical approach emerges as a technique aiming at overcoming the limitations posed by rectal cancer and other surgical fields of difficult access, in order to obtain better outcomes and a shorter learning curve.

Material And Methods: A systematic review of the literature of robot-assisted rectal surgery was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.

Is the interval from surgery to ileostomy closure a risk factor for low anterior resection syndrome?

Aim: Low anterior resection syndrome (LARS) comprises a collection of symptoms affecting patients after restorative surgery for rectal cancer. The aim of the present study was to analyse the incidence of LARS in patients undergoing rectal cancer surgery with and without subsequent ileostomy and to determine whether the interval to ileostomy closure is a factor associated with its occurrence.

Method: All patients undergoing curative anterior resection for rectal cancer from 2008 to 2012 in our institution were included in the study.

The role of tridimensional dynamic ultrasound for pelvic floor evaluation.

Introduction: Dynamic endoanal ultrasound has emerged in recent years as a test that could replace the now existing tests in the diagnosis of pelvic floor disorders. The aim of this paper is to determine the usefulness of echodefecography in the diagnosis and evaluation of patients with symptoms of anorrectal obstruction, and show the results obtained after its implementation in a pelvic floor unit, as a complementary tool that could replace conventional defecography.

Methods: In this retrospective study we analyzed 66 patients with a mean age of 55 years (19-83), 61 women (92%).

Effectiveness of a three-dimensional anorectal ultrasound in perianal Crohn's disease: incompatibility with clinical and surgical examinations.

Purpose: We have correlated the 3D anorectal ultrasound (3D ARU) findings with clinical examination and the surgical findings and examined its capacity to provide ancillary information, which potentially alters patient management.

Patients And Methods: This is a prospective analysis conducted at a tertiary academic hospital. A total of 95 patients were included.

Analysis of conversion factors in robotic-assisted rectal cancer surgery.

Background: Robotic surgical management of rectal cancer has a series of advantages which might facilitate the surgical approach to the pelvic cavity and reduce conversion rates. The aim of the present study is to identify independent factors for conversion during robotic rectal cancer surgery.
