Influence of surgical site infection on oncological prognosis after curative resection for colorectal cancer: An observational single-institution study.

Background: An exacerbated inflammatory response to post-operative infection could favor an environment in which residual viable tumor cells present in the surgical bed, bloodstream, or occult micrometastases can survive and progress to produce local or distant recurrence. In this regard, a surgical site infection (SSI) could be an important risk factor for disease progression. This study aimed to investigate the impact of SSI on long-term survival and recurrence of colorectal cancer.

Laparoendoscopic Single-Site Cholecystectomy: First Experiences with a New Standardized Technique Replicating the Four-Port Technique.

Background: After reports on laparoendoscopic single-site (LESS) cholecystectomy, concerns have been raised over the level of difficulty and a potential increase in complications when moving away from conventional gold standard multiport laparoscopy due to incomplete exposure and larger umbilical incisions. With continued development of technique and technology, it has now become possible to fully replicate this gold standard procedure through an LESS approach. First experiences with the newly developed technique and instrument are reported.

Unnoticed biloma due to liver puncture after Veress needle insertion.

Laparoscopic surgery has become more widespread in the last years. Creating the pneumoperitoneum is the first surgical procedure but it is still responsible for many of the adverse events described in this field. Until now, liver puncture producing a delayed biloma has not been described.

[Spleen-preserving surgery after blunt abdominal trauma with splenic hilum involvement].

Background: Splenic involvement secondary to blunt abdominal trauma is often treated by performing a splenectomy. The severity of the post-splenectomy syndrome is currently well known (blood loss, sepsis), so there is an increasing tendency to preserve the spleen. The case is presented of splenic preservation after blunt abdominal trauma with hilum involvement, emphasising the role of Floseal as a haemostatic agent, as well as the use of resorbable meshes to preserve the spleen.

Prevention of parastomal hernia with a preperitoneal polypropelene mesh.

Objective: To show our results with the use of a polypropylene mesh at the stoma site, as prophylaxis of parastomal hernias in patients with rectal cancer when a terminal colostomy is performed.

Methods: From January 2010 until March 2014, 45 consecutive patients with rectal cancer, underwent surgical treatment with the need of a terminal colostomy. A prophylactic mesh was placed in a sublay position at the stoma site in all cases.

Gallbladder leiomyoma in absence of immune system disorders: an unusual diagnosis.

Mesenchymal neoplasms of the gallbladder are rare and in particular leiomyomas of the gallbladder have been rarely reported, all of them in patients with immune system disorders.This is the first report in Spanish of a 23-year-old female patient with a gallbladder leiomyoma without associated immunodeficiency. The patient lacks a previous history of uterine leiomyoma or any other form of neoplasm.

[Diverticulectomy and cricopharyngeal myotomy for the treatment of Zenker's diverticulum. a presentation of 33 cases].

Introduction: The classic treatment of Zenker's diverticulum (ZD) has been cricopharyngeal myotomy (CPM), with the need or not to resect it being argued (diverticulectomy versus diverticulopexy). However, the advance of endoscopic techniques requires new treatment strategies to be established. We analyse the complications and clinical results of our series with cricopharyngeal myotomy and diverticulectomy in patients with ZD.

Magnetic-assisted single-port sleeve gastrectomy.

Background: Sleeve gastrectomy is a recent, purely restrictive procedure in bariatric surgery that has shown results similar to gastric bypass over the short and middle term. At the same time, single-port access surgery has fostered the development of new techniques and methods seeking better cosmetic results and less postoperative pain, while maintaining the satisfactory results obtained by the standard laparoscopic approach. One of the problems associated to single-access surgery is the lack of traction and the difficulties to retract the liver.

Total intracorporeal anastomosis during single-port laparoscopic right hemicolectomy for carcinoma of colon: a new step forward.

Background: Laparoscopic surgery is a feasible option for colonic carcinoma as short-and long-term results show. This technique is as safe and effective as the open approach. Single-port access surgery is considered a new minimally invasive approach in the search for better cosmetic results and less postoperative pain.
