Effect on iron deficiency anemia of laparoscopic repair of large paraesophageal hernias.

Patients with iron deficiency anemia sometimes have a large paraesophageal hernia and no other explanation for their chronic blood loss. The management of these patients can be a dilemma, especially when the hernia is otherwise asymptomatic. We aimed to determine whether a laparoscopic repair of the hernia could cure the anemia. We reviewed a consecutive series of 11 cases of iron deficiency anemia associated with a large paraesophageal hernia, many without associated linear gastric erosions, managed by laparoscopic repair and fundoplication. There was one conversion in a patient with dense adhesions from previous upper abdominal surgery. Another patient required a laparoscopic reoperation for an early recurrence. Major morbidity occurred in three patients and there was no mortality. There was no recurrence of anemia after a median follow-up of more than 2 years. Iron deficiency anemia in association with a large paraesophageal hernia can be treated by laparoscopic repair with acceptable morbidity and minimal mortality. The complications of a large paraesophageal hernia are also prevented.
