Background: The presence of native umbilical defects in adults and their use as laparoscopic first entry site is poorly documented. It would be a likely safer method than the Veress needle and the direct trocar insertion. This work aimed at reporting its prevalence, size and its relationship to gender, age and body mass index.

Methods: In 160 consecutive laparoscopic operations a trans-umbilical incision was done and a defect at its base was looked for. When found it was measured and used as the first port entry site. Relationships of a native defect presence and their sizes to gender, age and BMI were analyzed.

Results: The prevalence of a native defect in this series was 90%. Its presence had no relation to either gender, age nor BMI. Its size, however positively correlated with both age and BMI. There were no complications related to its use for first laparoscopic entry.

Conclusion: A native umbilical defect is present in 90% of adults. Whenever present, it is recommended for use as the first port entry site by an open technique. This method is simple, safe and avoids unnecessarily inducing another defect.
