The influence of the percentage of the common limb in weight loss and nutritional alterations after laparoscopic gastric bypass.

Background: Roux-en-Y gastric bypass (RYGB) is considered the gold standard for the treatment of morbid obesity. There is no consensus over ideal limb length when the bypass is created and published studies do not take into account the influence of the common limb (CL) on weight loss. The objective was to study the influence of the common limb after RYGB.

The learning curve of laparoscopic treatment of rectal cancer does not increase morbidity.

Introduction: The treatment of rectal cancer via laparoscopy is controversial due to its technical complexity. Several randomized prospective studies have demonstrated clear advantages for the patient with similar oncological results to those of open surgery, although during the learning of this surgical technique there may be an increase in complications and a worse prognosis.

Objective: Our aim is to analyze how the learning curve for rectal cancer via laparoscopy influences intra- and postoperative results and oncological markers.

Randomized prospective study to compare laparoscopic appendectomy versus umbilical single-incision appendectomy.

Introduction: The use of single-incision laparoscopic surgery may represent an improvement over conventional laparoscopic surgery. In recent years, more and more articles have been published demonstrating the feasibility of this approach. Hence, for this reason, we present this randomized prospective study to compare the 2 techniques.

[Afferent loop stimulation prior to ileostomy closure].

There is a 17% complications rate after ileostomy closure, with paralytic ileus being the most common. With the aim of reducing this complication, stimulation via the afferent loop was performed daily for the 2 weeks prior to the stoma.
