Impaired postoperative EGJ relaxation as a determinant of post laparoscopic fundoplication dysphagia: a study with high-resolution manometry before and after surgery.

Background: Laparoscopic fundoplication (FP) reduces gastroesophageal reflux (GER) efficiently. Dysphagia is its main complication, but no clear data have been published in literature to evaluate risk factors associated with it. The goal of this retrospective study was to identify factors associated with dysphagia occurring after FP for GER disease, with high-resolution manometry (HRM) performed before and after surgery.

Achalasia-like disorder after laparoscopic adjustable gastric banding: a reversible side effect?

Literature data concerning the effect of laparoscopic adjustable gastric banding (LAGB) on esophageal motility are conflicting. Achalasia-like disorder involving the absence of esophageal peristalsis and impaired esophago-gastric junction (EGJ) is probably under-estimated and can result in failure and band removal. The aim of our study was to focus on cases of achalasia-like disorder and study its evolution after band deflating or removal.

Laparoscopic gastric bypass for failure of adjustable gastric banding: a review of 85 cases.

Laparoscopic adjustable gastric banding (LAGB) is the first bariatric procedure in Europe and is becoming more and more popular in North America. However, the failure rate at 5 years can reach 50%. Although there is still no consensus on revisional surgery, the trend seems to be in favor of conversion to gastric bypass (GBP) with encouraging results.

Laparoscopic repair of large hiatal hernia without prosthetic reinforcement: late results and relevance of anterior gastropexy.

Background: Laparoscopic treatment of large hiatal hernias seems to be associated with a high recurrence rate that some authors suggest to bring down by performing prosthetic closure of the hiatus. However, prosthetic repair remains controversial owing to severe and still underestimated complications. The aims of this study were to assess the long-term functional and objective results of laparoscopic treatment without prosthetic patch, and to identify the risk factors of recurrence.

Post-operative pressure lability and cardiac baroreflex in normotensive patients as a function of age.

Background: Pressure lability may be linked to the loss of the cardiac baroreflex. The reduction of the sensitivity of the cardiac baroreflex has not been delineated in the post-operative period according to age in normotensive patients. This study addresses pressure lability and slope of the cardiac baroreflex as a function of age.
