Abstract
Forty-one patients (17 men and 24 women) were treated with progressive pneumoperitoneum before repair of giant incisional hernias. The pneumoperitoneum was induced using nitrous oxide gas and a laparoscopic insufflator, and was topped up every other day for a mean of 5·5 days with a total injection of 23·2 litres of nitrous oxide. The pneumoperitoneum was well tolerated in 30 patients, caused a mild temporary pain in 10 patients and a sharp pain in one patient; no serious side-effects occurred. All the patients underwent surgery to repair their hernias, 40 patients were available for follow-up for a mean of 25·3 months, only two hernias recurred both within 4 months of the operation.
