Mesh erosion into caecum following laparoscopic repair of inguinal hernia (TAPP): a case report and literature review.

摘要

Repair of inguinal hernia is the most commonly performed surgical procedure. Both open and laparoscopic methods are accepted modalities of surgical treatment. Transabdominal preperitoneal (TAPP) and total extraperitoneal (TEP) are the two types of laparoscopic repair of the inguineal hernia. The main advantages of laparoscopic repair, as compared to open repair, are a shorter hospital stay and a quicker recovery to normal activities. However, laparoscopic repairs are associated with a higher incidence of visceral and vascular injuries. One particular complication is the migration and erosion of mesh into the adjacent viscera. Although the total numbers of cases are small, compared to the total numbers of inguinal hernia repairs, they are important, as they often presented with a diagnostic dilemma. Most of the mesh migrations reported in the literature involves the urinary bladder. In this paper, we present a case of erosion of mesh into the caecum. The patient (a 66-year-old male) underwent TAPP repair of a right inguinal hernia in 1996 with polypropelene mesh. He also underwent an open appendicectomy in 1980. During the laparoscopic repair, he was found to have multiple intra-abdominal adhesions. He presented with intermittent diarrhea, for which he was investigated, and a benign caecal lesion was found. He was initially managed conservatively. However, his symptoms persisted and he underwent a right hemicolectomy in February 2006 in our hospital. The offending lesion was found to be the prolene mesh having eroded into the caecum.
