In Reply We would like to thank Acuna and colleagues for their Letter to the Editor with a thorough analysis of our recently published article,¹ which directed our attention to the reported severe complication rate. Our article correctly stated that there was no significant difference in severe complications between the groups at long-term follow-up; however, unfortunately there was an error in the count of complications (Table 2 and in the Results section¹). We have taken the appropriate measures to correct this mistake.² The conclusions of the study are unaltered.

It is correct that the observed nonsignificant difference in severe complications between laparoscopic lavage and resection had almost disappeared at 5-year follow-up (corrected count: 21 [29%] vs 17 [25%], respectively; P = .58). However, this was evident at 1-year follow-up (27% vs 21%; P = .45) and was mainly due to laparotomy-related complications in the resection group (wound dehiscence and hernia surgery).³ The observed nonsignificant difference in all-cause mortality might be a result of the slight age difference between the groups. Unfortunately, few patients in Norway and Sweden are autopsied. Cause of death records are consequently unreliable, which is why only all-cause mortality was reported.¹ The cause of death was unavailable in 9 patients and recorded disease-related mortality was 6 of 23 (26%) in the laparoscopic lavage and 4 of 17 (24%) in the resection group, respectively (P = .85).
