Management of epiphrenic esophageal diverticula. A fifteen-year experience.

Epiphrenic esophageal diverticula represent an unusual cause of dysphagia, pain, and weight loss. Although commonly associated with motility disorders, distal esophageal diverticula also have been associated with reflux strictures or other lesions. To determine the most appropriate diagnostic evaluation and operative approach, we reviewed the recent 15-year experience with epiphrenic esophageal diverticula at our institution. Over the study period, 18 patients were diagnosed with pulsion epiphrenic diverticula. Nine patients (50%) with symptomatic diverticula were referred for surgical management. All referred patients were evaluated with preoperative manometry, endoscopy, and contrast esophagography. Diverticulectomy was performed via posterolateral thoracotomy in all patients, combined with myotomy in the 6 patients (67%) with abnormal manometric results and in 2 patients with normal manometric results. The third patient with normal manometric results underwent simple diverticulectomy. There was no operative mortality. One complication, a small esophageal leak, was managed successfully by early reoperation. All patients were free of dysphagia at discharge. Follow-up was obtained for 17 patients (94%) ranging from 3 months to 12 years. Good to excellent results (measured by relief of symptoms, weight gain, and absence of clinical recurrence) were seen in all 9 surgical patients; 6 of 9 nonsurgical patients remained or became symptomatic. This experience demonstrates the efficacy of surgical management of symptomatic epiphrenic esophageal diverticula. Diverticulectomy combined with selective myotomy permits excellent operative results and resolution of associated symptoms.

Treatment of complicated congenital splenic cysts.

Although rare in occurrence, the potential for congenital splenic cysts to enlarge, rupture, or become infected has been well documented. Presented is the case of a 13-year-old boy with an infected epidermoid cyst of the spleen, which presented as a solitary splenic abscess. The entity has traditionally been treated by splenectomy or, more recently, percutaneous drainage. However, given the inability of percutaneous drainage or sclerotherapy to permanently obliterate congenital splenic cysts, the authors managed this condition with percutaneous drainage and interval partial splenectomy. This achieves complete removal of the lesion while preserving splenic function.

Rectus turnover flaps for the reconstruction of large midline abdominal wall defects.

Large midline abdominal hernias are reconstructed with bilateral rectus turnover flaps in a series of 15 patients. Each rectus muscle is turned over from a retracted lateral position to the midline, providing a complete abdominal closure with fascia and muscle. The repairs were frequently reinforced with synthetic materials, but synthetic material was not placed over bowel and simply sutured to the edge of a large hernial defect. The rectus turnover method of reconstruction appears to have significant advantages over the use of synthetic material alone. Successful hernia repair was accomplished in all patients. The surgical technique and complications encountered are described in detail.
