BACKGROUND Drain-site hernia(DSH)has an extremely low morbidity and has rarely been reported.Small bowel obstruction is a frequent concurrent condition in most cases of DSH,which commonly occurs at the≥10 mm drain-site.Here we report a rare case of DSH at the lateral 5 mm port site one month postoperatively without visceral incarceration.Simultaneously,a brief review of the literature was conducted focusing on the risk factors,diagnosis,and prevention strategies for DSH.CASE SUMMARY A 76-year-old male patient was admitted to our institution with intermittent abdominal pain and a local abdominal mass which occurred one month after laparoscopic radical resection of rectal cancer one year ago.A computed tomography scan showed an abdominal wall hernia at the 5 mm former drain-site in the left lower quadrant,and that the content consisted of the large omentum.An elective herniorrhaphy was performed by closing the fascial defect and reinforcing the abdominal wall with a synthetic mesh simultaneously.The postoperative period was uneventful.The patient was discharged seven days after the operation without surgery-related complications at the 1-mo follow-up visit.CONCLUSION Emphasis should be placed on DSH despite the decreased use of intra-abdominal drainage.It is recommended that placement of a surgical drainage tube at the≥10 mm trocar site should be avoided.Moreover,it is advisable to have a comprehensive understanding of the risk factors for DSH and complete closure of the fascial defect at the drainage site for high-risk patients.
