Primary lymphoma of the small intestine is a heterogeneous group of diseases reflected in its protean imaging features. This review illustrates the widespread appearances seen on imaging methods (primarily CT and barium studies) with pathological correlation.
Surgical therapy (Heller myotomy) is the most effective treatment to relieve dysphagia associated with achalasia. The advent of minimally invasive techniques, specifically the laparoscopic approach, significantly reduced the morbidity of surgical therapy, making it the procedure of choice for most patients who have achalasia. Pneumatic dilatation is a viable alternative, though is associated with inferior results and a higher risk of esophageal perforation than surgical therapy. Pharmacotherapy and Botox provide inferior results and should be reserved for temporizing therapy, or for patients who are deemed too frail for surgical intervention. For best results, a laparoscopic myotomy should be carried at least 3 cm onto the stomach, and a partial fundoplication should be performed to reduce the incidence of postoperative GE reflux.
The rational treatment of esophageal cancer requires the complete evaluation and preoperative staging of this disease. As the incidence of esophageal cancer increases, more clinicians will face the difficult task of allocating the appropriate treatment course for these patients. Accurate esophageal cancer staging is critical if stage-dependent algorithms are used to direct appropriate therapies. Although all of the staging techniques discussed may potentially provide useful information, it is not possible to use all techniques in all patients, especially given the limited availability of resources. The optimal staging strategy has not yet been determined; the authors provide the general algorithm used in our institution. Ultimately,minimally invasive surgical approaches will allow surgeons to evaluate locoregional disease with little or no procedure-associated morbidity, much as mediastinoscopy is used in lung cancer staging. Although currently the use of molecular biologic techniques may only be investigational, it holds great promise in the future.
