Laparoscopic esophagomyotomy is the preferred approach to patients with achalasia of the esophagus, However, there are very few long-term follow-up studies (>10 years) in these patients. ⋯ In patients with achalasia submitted to esophagomyotomy and Dor's antireflux procedure, there is a progressive clinical deterioration of initially good results if a very long follow-up is performed (23 years after surgery), mainly due to an increase in pathologic acid reflux disease and the development of short- or long-segment Barrett esophagus.

Randomized Controlled Trial Comparative Study
Three-year follow-up of a prospective randomized trial comparing laparoscopic versus open gastric bypass.
To analyze long-term weight loss, changes in comorbidities and quality of life, and late complications after laparoscopic and open gastric bypass. ⋯ In this randomized trial with a 3-year follow-up, we found that laparoscopic gastric bypass was equally effective as open gastric bypass with respect to weight loss and improvement in comorbidities and quality of life. A major advantage at long-term follow-up for patients who underwent laparoscopic gastric bypass was the reduction in the rate of incisional hernia.

To identify risk factors for complications after resection for esophageal or cardia cancer. ⋯ High-volume esophageal surgeons seem to lower the risk of anastomotic leakage. More large-scale studies are warranted to establish the roles of the other potentially important risk factors suggested in our study.

Meta Analysis Comparative Study
Laparoscopic versus open appendectomy in children: a meta-analysis.
This study aims to use meta-analysis to compare laparoscopic and open appendectomy in a pediatric population. ⋯ The results of this meta-analysis suggest that laparoscopic appendectomy in children reduces complications. However, we also see the need for further high-quality randomized trials comparing the 2 techniques, matched not only for age and sex but also for obesity and severity of appendicitis.
