Modified Nissen fundoplication for reduction of fundoplication failure.

Failure of the Nissen fundoplication can be secondary to disruption of the wrap or slippage of the stomach upward within the wrap. A modification of the Nissen fundoplication was devised and implemented between 1982 and 1995 to eliminate these complications. This report describes the modification and the results. Commonly, the Nissen fundoplication uses a single anterior row of sutures securing the wrapped stomach to the esophagus. This modification reinforces the wrap with two additional rows of suture, one right lateral and one left lateral, each further anchoring the wrapped stomach to the esophagus. This retrospective analysis compares the Nissen and modified Nissen fundoplications performed at our institution. Fundoplication operations were considered a failure if they required a reoperation secondary to wrap disruption or stomach slippage. Data were analyzed using the chi 2 method. A total of 948 fundoplication procedures were performed; 326 Nissen and 622 modified Nissen. Follow-up ranged from 0.5 to 13 years (mean, 6 years). Thirteen wrap disruptions and six stomach slippages occurred in the Nissen group (5.8%); 10 wrap failures and no stomach slippages occurred in the modified Nissen group (1.6%), P < .05. The authors conclude that this modification of the Nissen fundoplication significantly reduces wrap disruptions and stomach slippages.
