Gastric surgery.

Abstract

Most significant research relating to gastric surgery in the past year has centered on surgery for gastroesophageal reflux disease (GERD). Antireflux surgery has become more popular with advanced laparoscopic technology. Two previously accepted surgical principles have been challenged by current studies: the importance of division of the short gastrics and the dictum that partial fundoplication is preferred for patients at risk for dysphagia. Additionally, risk factors for postoperative dysphagia have been identified, allowing for better patient selection and education. Further study on the cause of GERD has shown a positive correlation between pathologic gastroesophageal reflux and those with hiatal hernia or disordered esophageal peristalsis, although cause or effect has not yet been established. Literature relating to bariatric surgery has confirmed the safety and efficacy of the laparoscopic Roux-en-Y gastric bypass, and several papers address the appropriateness of prophylactic cholecystectomy in these patients. The role of laparoscopic surgery for treatment of perforated peptic ulcer disease has now been validated, with subsequent eradication of Helicobacter pylori infection. The relationship of H. pylori infection to acutely bleeding ulcers is less clear. Indications for ulcer surgery are predominantly limited now to perforation and bleeding because of the availability of effective acid-reducing medications and recognition of the role of H. pylori infection.
