Simultaneous Treatment of Complex Incisional Hernia and Stoma Reversal.

The simultaneous repair of incisional hernias (IH) and the reconstruction of the intestinal transit may pose a challenge for many surgeons. Collaboration between units specialized in abdominal wall and colorectal surgery can favor simultaneous treatment. Descriptive study of patients undergoing simultaneous surgery of complex IH repair and intestinal transit reconstruction from the start of treatment in a joint team.

Multicentre, prospective, randomized control non-inferiority trial of bladder catheter management in colon surgery.

Aim: Perioperative bladder catheterization is a controversial issue. Most current recommendations are based on data from open surgery extrapolated to enhanced recovery after surgery or fast-track programmes ranging between 24 and 48 h. The aim of this study is to provide a rationale for reducing catheterization time while at the same time avoiding acute urine retention (AUR), in patients undergoing scheduled laparoscopic colon surgery.

Randomised clinical trial to test the phenolization in sacrococcygeal pilonidal disease.

To test the efficacy and safety of phenolization in uncomplicated Sacrococcygeal pilonidal disease (SPD) the phenolization in uncomplicated SPD is feasible and secure in selected patients in observational studies. The greatest benefits are obtained to reduce the length of sick leave (LSL) and complications. Single-center randomised controlled clinical trial.

Protective properties of grape-seed proanthocyanidins in human ex vivo acute colonic dysfunction induced by dextran sodium sulfate.

Purpose: Anti-inflammatory and barrier-protective properties have been attributed to proanthocyanidins in the context of intestinal dysfunction, however little information is available about the impact of these phytochemicals on intestinal barrier integrity and immune response in the human. Here we assessed the putative protective properties of a grape-seed proanthocyanidin extract (GSPE) against dextran sodium sulfate (DSS)-induced acute dysfunction of the human colon in an Ussing chamber system.

Methods: Human proximal and distal colon tissues from colectomized patients were submitted ex vivo for a 30-min preventive GSPE treatment (50 or 200 µg mL) followed by 1-h incubation with DSS (12% w v).

Evaluation of the impact of preoperative education in ambulatory laparoscopic cholecystectomy. A prospective, double-blind randomized trial.

Introduction: Outpatient laparoscopic cholecystectomy is a safe procedure and provides a better use of health resources and perceived satisfaction without affecting quality of care. Preoperative education has shown less postoperative stress, pain and nausea in some interventions. The principal objective of this study is to assess the impact of preoperative education on postoperative pain in patients undergoing ambulatory laparoscopic cholecystectomy.

Transanal endoscopic surgery in rectal cancer.

Total mesorectal excision (TME) is the standard treatment for rectal cancer, but complications are frequent and rates of morbidity, mortality and genitourinary alterations are high. Transanal endoscopic microsurgery (TEM) allows preservation of the anal sphincters and, via its vision system through a rectoscope, allows access to rectal tumors located as far as 20 cm from the anal verge. The capacity of local surgery to cure rectal cancer depends on the risk of lymph node invasion.

Retracted: Impact on quality of life of using an onlay mesh to prevent incisional hernia in midline laparotomy: a randomized clinical trial.

Background: Recent studies have demonstrated the effectiveness of using prophylactic meshes to achieve abdominal wall closure, decreasing the risk of incisional hernia. However, the effect of prophylactic mesh placement on a patient's quality of life has not yet been evaluated.

Study Design: A controlled, prospective, randomized, and blind study was carried out.

Transanal endoscopic surgery with total wall excision is required with rectal adenomas due to the high frequency of adenocarcinoma.

Background: Colorectal adenomatous polyps are considered premalignant lesions, although a high percentage are already malignant at the time of their removal. Full-thickness excision in patients with adenoma detected in preoperative biopsy enables much more accurate pathology examination and has shown that local surgery is appropriate for T1 adenocarcinoma.

Objective: To determine whether full-thickness excision during transanal endoscopic surgery is the treatment of choice for rectal adenoma, and to identify possible predictors of invasive adenocarcinoma associated with this type of lesion.

Transanal endoscopic microsurgery with 3-D (TEM) or high-definition 2-D transanal endoscopic operation (TEO) for rectal tumors. A prospective, randomized clinical trial.

Purpose: Transanal endoscopic microsurgery (TEM) is a three-dimensional viewing endoscopic system procedure which provides access to rectal tumors through a rectoscope. Two-dimensional transanal endoscopic operation (TEO), with the introduction of high-definition vision, achieves results that are comparable to those of the classical TEM. The main aim of the study was to compare the effectiveness of TEO and TEM systems in a prospective, randomized clinical trial.

[Intra-abdominal desmoid tumor mimicking a pancreatic tumor in a patient with familial colonic polyposis].

Introduction: Fibromatosis consists of a benign fibroblastic proliferation with local infiltrative growth. Two types are recognized: a superficial and a deep form, also known as desmoid tumor. The latter may occur sporadically or in association with familial adenomatous polyposis and Gardner's syndrome.
