[Medium term results on introducing colorrectal laparoscopic surgery into clinical practice after having an intensive training course].

Introduction: Endoscopic surgery has characteristics that increase the difficulties of learning. Five years ago, an intensive colorectal laparoscopic surgery course was designed to offer training in the technical bases of this type of surgery. The aim of this article is to determine the impact of the colorectal surgery course on clinical practice, and to investigate the factors that limit its applicability and the training preferences of the surgeons.

Thymidylate synthase germline polymorphisms in rectal cancer patients treated with neoadjuvant chemoradiotherapy based on 5-fluorouracil.

Purpose: Chemoradiotherapy using 5-fluorouracil has shown to be effective treatment for rectal cancer. Thymidylate synthase (TS) is an important target enzyme for the fluoropyrimidines. However, the predictive role of TS levels in early stage rectal cancer is not yet well understood.

[Laparoscopic treatment of rectal prolapse].

Introduction: Rectal prolapse is an uncommon disease mainly seen in patients of advanced age. It is treated surgically, although there is still significant controversy as regards the most appropriate technique. In the last few years the laparoscopic route has been shown to be feasible and has the advantage of being a minimally invasive technique.

Energy sources for laparoscopic colectomy: a prospective randomized comparison of conventional electrosurgery, bipolar computer-controlled electrosurgery and ultrasonic dissection. Operative outcome and costs analysis.

The development of operative laparoscopic surgery is linked to advances in ancillary surgical instrumentation. Ultrasonic energy devices avoid the use of electricity and provide effective control of small- to medium-sized vessels. Bipolar computer-controlled electrosurgical technology eliminates the disadvantages of electrical energy, and a mechanical blade adds a cutting action.

Mesh in the hiatus: a controversial issue.

Objective: To analyze the experience acquired to date on the use of prosthetic mesh to prevent recurrence after laparoscopic repair of paraesophageal hernia.

Data Sources: Current English-language literature review.

Study Selection: Case reports, series, and opinion articles on the use of mesh for paraesophageal hernia repair.

The massive hiatal hernia: dealing with the defect.

The success of laparoscopic fundoplication has extended the use of the laparoscopic approach to treating more difficult situations such as paraesophageal hernias (PEHs) or type III (mixed) hiatal hernia. The results have shown that laparoscopic repair is feasible and safe. However, several series have shown recurrence rates of up to 42% as a result of difficulty in the closure of the hiatal gap.

Minimally invasive treatment for obstructive tumors of the left colon: endoluminal self-expanding metal stent and laparoscopic colectomy. Preliminary results.

Background: Obstruction of the left colon may be the first manifestation of colorectal cancer. Resection of the colonic segment involved and the construction of an end colostomy (Hartman's procedure) is the most frequent treatment. Alternatives to the placement of a stoma are subtotal colectomy or intraoperative lavage of the colon and primary anastomosis, but their application depends on intraoperative findings and the availability of a skilled surgeon.

Laparoscopic surgery in situs inversus: a literature review and a report of laparoscopic sigmoidectomy for diverticulitis in situs inversus.

Background: Situs inversus (SI) is a rare autosomal recessive congenital defect in which the position of abdominal and/or thoracic organs is a "mirror image" of the normal one, in the sagittal plain. In 25% of these cases, SI is part of the Kartagener syndrome, together with bronchiectasis and chronic sinusitis.

Methods: We present a case of a patient with Kartagener syndrome and complete SI that was laparoscopically operated on for diverticulitis.

Laparoscopic treatment for intussusception of the small intestine in the adult.

The term intussusception refers to a spontaneous invagination of a portion of the intestine into another bowel loop. Its incidence is higher in children, but in adults it causes 1% to 5% of intestinal obstructions. The diagnosis of intussusception in the adult is difficult due to the variability of the symptoms.

Hand-assisted laparoscopic surgery.

Hypothesis: Hand-assisted laparoscopic surgery (HALS) has been proposed as a useful alternative to conventional open or laparoscopic surgery. However, most information is fragmented and comes from specific or selective indications. To assess the current situation of HALS, a general overview of the fields of application, results, and quality of the evidence of these results is necessary.
