The majority of inguinal hernia repairs today, open or laparoscopic, are performed with mesh tension-free repair. The introduction of mesh, though beneficial, posed a new set of post-operative problems related with the mesh, and mesh migration or penetration is one of the most unusual ones with considerable morbidity. Mesh migration following laparoscopic repair is rare, and only a handful of cases have been reported in the literature. Here we present the first ever case report of mesh migration and penetration through rectum developing after two years post-operatively. The mesh was removed and the patient was discharged in a stable condition.

Mesh hernioplasty by endoscopic technique may have rare complications. This is the first ever case report of trans-rectal mesh penetration after total extraperitoneal (TEP) repair. We re-emphasize that the mesh must be implanted absolutely flat without any wrinkles close to the pelvic floor after adequate parietalization of hernial sac, and every effort should be made to identify and close any inadvertent peritoneal breach in TEP repair of inguinal hernia so as to avoid any mesh migration or penetration. Though the meticulous technique remains the established rule, some extremely rare complications may occur after TEP repair requiring astute awareness of surgeons.

  Introduction Top

It is well known that the inguinal hernia repair is one of the most commonly performed surgical procedures. Laparoscopy is a valid alternative to traditional open techniques for the treatment of hernia by the placement of mesh.[1] In the last two decades, this approach tends to become the gold standard procedure for the inguinal hernia. Late complication following laparoscopic approach is very low. We report the first ever case of mesh penetration through rectum as a delayed complication following totally extraperitoneal repair (TEP).

  Case History Top

A 60-year-old man with a body mass index of 28 kg/m2 presented with complaints of something coming out from anal opening for last 2 days along with vague lower abdominal discomfort. There was no recent history of vomiting, abdominal distension, fever, altered bowel habits, and abdominal trauma. The patient had undergone laparoscopic TEP repair of bilateral inguinal hernia 2 years back by using two meshes (one on each side) of size 15 × 12 cm polypropylene mesh (pore size of 164 × 96 µm and weight of 80-85 g/m2) along with non-absorbable spiral tack fixation and an uneventful post-operative period about 2 years back with an uneventful post-operative period. The patient had no other co-morbid medical or surgical illness. On examination, he was afebrile with stable hemodynamic parameters. A small non-tender bulge was present in the left iliac fossa and suprapubic region. Digital rectal examination revealed a foreign body (mesh) being felt about 5–6 cm from the anal verge. His laboratory parameters included normal total leucocyte count of 8,600 and mildly raised C-reactive protein level of 6.4 mg/L. His abdominal radiograph [Figure 1] showed multiple spiral-shaped radio-opaque shadows (non-absorbable tacks) in the region of rectum. Contrast-enhanced tomography was suggestive of well-defined hyperdensity noted in the rectum with mild circumferential thickening of rectal wall and perirectal fat plane stranding with few air specks noted within the right antero-lateral wall of the rectum near the intraluminal hyperdensity [Figure 2]. The mesh along with non-absorbable tacks was removed manually under spinal anesthesia [Figure 3]. Post-operative recovery was uneventful, and the patient was discharged on oral antibiotics and analgesics. Bulge in left iliac fossa subsided itself after 8 weeks and subsequent colonoscopy revealed normal anal canal, rectum, and colon with no evidence of ulcer or thickening and he underwent bilateral open hernioplasty (Lichtenstein repair). After 1 year of follow-up, the patient is presently not having any complaints.

  Discussion Top

Late complications related to mesh usage are rare. Mesh infection is one of them, with an estimated incidence of 0.1–0.2% after laparoscopic inguinal hernia repair.[2],[3],[4] Till date, very few cases of migration of mesh after endoscopic inguinal hernia repair have been reported so far and in three of them mesh migrated into the urinary bladder out of which two of them occurred in the transabdominal preperitoneal repair.[5],[6] Other cases included combined mesh infection with mesh migration following TEP repair,[7] and a single case reported mesh migration into small bowel, leading to obstruction.[8] In all of these cases, patients underwent laparotomy and mesh removal. Another study has investigated mesh migration and the position of the hip joint in TEP[9] and described the need for minimizing the strenuous activity and bending in the immediate post-operative period, during which mesh and staples have the greatest risk of dislodging.

In this case report, we propose that the mesh edges might have impinged upon the surface of rectosigmoid through some inadvertent peritoneal breach leading to chronic subclinical inflammation and subsequent penetration of mesh as the most likely explanation of sequence of events. As the patient did not have any abdominal complaints, his mesh removal through anal canal was uneventful with minimal post-operative morbidity.
