Safety and feasibility of a new rectoscope in rectal cancer surgery. First clinical trial.

We present a first in human clinical trial of a new rectoscope that shows, by means of transillumination, the optimal point of transection of the rectum in oncologic surgery. The device was developed together with a team of engineers and was manufactured by 3D printing. Eighteen patients with a mean age of 71 years and a mean distance from the tumor to the anal margin measured by colonoscopy of 10.

Quality of life and low anterior resection syndrome before and after deep endometriosis surgery.

Purpose: Deep endometriosis (DE) is defined by the presence of ectopic endometrial glands, with rectal involvement ranging from 5.3 to 12%. The prevalence of low anterior resection-like syndrome (LARS) in patients with DE, how it affects quality of life (QoL), and its evolution after surgery is unclear.

Surgeons' workload assessment during indocyanine-assisted deep endometriosis surgery using the surgery task load index: The impact of the learning curve.

Objective: Assess the surgeons' workload during deep endometriosis surgery after ureteral ICG.

Design: Prospective, consecutive, comparative, single-center study.

Population: 41 patients enrolled to deep endometriosis surgery with ureteral ICG from January 2019 to July 2021 at La Paz University Hospital.

Mindfulness based intervention through mobile app for colorectal cancer people awaiting surgery: A randomized clinical trial.

Introduction: Colorectal cancer is the third most common cancer worldwide both in men and women. Around one-third of patients with cancer will suffer from anxiety or depression symptoms. The aim of this study was to evaluate the effectiveness of a Mindfulness-based stress reduction intervention through a mobile application ("En Calma en el Quirófano").

Short-term outcomes in patients undergoing laparoscopic surgery for deep infiltrative endometriosis with rectal involvement: a single-center experience of 168 cases.

Purpose: The surgical management of deep infiltrative endometriosis (DE) involving the rectum remains a challenge. The objective of this study was to assess the outcomes from a single tertiary center over a decade with an emphasis on the role of a protective loop ileostomy (PI).

Methods: A retrospective review of outcomes for 168 patients managed between 2008 and 2018 is presented including 57 rectal shaves, 23 discoid excisions, and 88 segmental rectal resections.

Upfront surgery versus self-expanding metallic stent as bridge to surgery in left-sided colonic cancer obstruction: A multicenter observational study.

Background: Oncological outcomes of self-expanding metallic stent used as a bridge to surgery in potential curative patients with left-sided colonic cancer obstruction remain unclear. The aim of this study was to investigate perioperative and mid-term oncological outcomes of 2 of the currently most commonly performed treatments in left-sided colonic cancer obstruction.

Methods: This is a retrospective multicenter study including patients with left-sided colonic cancer obstruction treated with curative intent between 2013 and 2017.

Stem cell therapy applied for digestive anastomosis: Current state and future perspectives.

Background: Digestive tract resections are usually followed by an anastomosis. Anastomotic leakage, normally due to failed healing, is the most feared complication in digestive surgery because it is associated with high morbidity and mortality. Despite technical and technological advances and focused research, its rates have remained almost unchanged the last decades.

Management of perianal fistula in inflammatory bowel disease: identification of prognostic factors associated with surgery.

Purpose: As one of the clinical manifestations of inflammatory bowel disease (IBD), perianal fistula disease (PFD) can potentially impact the patient quality of life. The management of PFD employs a multidisciplinary approach which includes antibiotics, biological therapies, immunomodulators, and surgery. We analyzed the outcome and prognostic factors of anal fistula surgery in IBD patients.

SARS-CoV-2 pandemic on the activity and professionals of a General Surgery and Digestive Surgery Service in a tertiary hospital.

Introduction: The rapid spread of SARS-CoV-2 infection has led to a radical reorganization of healthcare resources. Surgical Departments need to adapt to this change.

Methods: We performed a prospective descriptive observational study of the incidence of COVID-19 in patients and surgeons of a General Surgical Department in a high prevalence area, between the 1st and 31st of March 2020.

Post-operative complications and recurrence rate after treatment of bowel endometriosis: Comparison of three techniques.

Objective: The aim of the present study was to compare post-operative complications and recurrence of three surgical techniques: segmental resection, discoid excision and nodule shaving.

Study Design: From January 2014 to December 2017, 143 patients who underwent segmental bowel resections for endometriosis at "La Paz" University Hospital, were enrolled and grouped by different techniques. We compared post-operative complications and recurrence rate in three groups: 76 (53%) patients underwent segmental resection (group I), 20 (14%) patients underwent discoid resection (group II) and 47 (33%) patients underwent rectal shaving (group III).

Systemic treatment of acute liver failure with adipose derived stem cells.

Purpose Of The Study: The definitive treatment for liver failure is, currently, liver transplantation. Research into other possible treatments, focused on achieving regeneration of the liver parenchyma, have led to the development of methods to generate hepatocytes from stem cells. In our study, we transplant allogenic adipose-derived stem cells (ASCs), not previously differentiated to hepatocytes, to treat acute liver failure induced by intraperitoneal administration of carbon tetrachloride (CCl4) in a Sprague-Dawley rat model.

Detection of hepatitis C virus in thyroid tissue from patients with chronic HCV infection.

Thyroid dysfunctions are common in chronic hepatitis C virus (HCV) infection. HCV-RNA has been detected by reverse-transcription polymerase chain reaction (PCR) in thyroid from HCV infected patients with acquired immunodeficiency syndrome. However, morphological evidence of HCV replication in thyroid cells from immune competent patients has not been provided.
