The routine application of NG tubes after surgery is not recommended for all patients. We suggest that NG tubes should be used according to the specific problems of each patient.

Introduction: Little data is available on the prognosis of esophageal cancer (EC) in Iran. We studied the short- and long-term survival of EC patients treated at the Cancer Institute of Iran. Methods: 619 patients were followed who had been operated in the years 1997-2006. The 1-month to 5-year survival rates of EC and hazard ratios (HR) for different prognostic factors were estimated. Results: Median survival was 11.5 months and 5-year survival was 10%. Patients at the advanced stage had a 2.1-fold higher risk of mortality compared to the early stage (95% CI 1.2-3.4). One-month mortality decreased from 12.2 in 1997-1999 to 9.1% in 2003-2006. In the first month, patients who were diagnosed in 2003-2006 had a significantly (60%) lower HR compared to 1997-1999 (HR = 0.4, 95% CI 0.1-0.9). In addition, patients with cardiopulmonary complications had an 11.7-fold higher HR compared to patients without complications (95% CI 4.7-29.3). Conclusions: The 5-year survival rate for operated EC patients was considerably low in Iran. Cardiopulmonary complications were the strong prognostic factors for first-month mortality. We suggest improving the pre- and postoperative care of EC to control these complications. Regular monitoring of patient survival is recommended to evaluate the effect of this intervention.

Two cases of bezoar formation after vagotomy and drainage are reported. A review of the literature reveals the stomach to be the most common site of bezoar formation after operations involving vagotomy, whereas most bezoars occurring after gastrectomy are found in the small intestine. The reasons for this difference are discussed, as well as the clinical features and treatment of bezoar.
