Introduction – Introduction of synthetic mesh was a landmark breakthrough in management of hernia repair and has signicantly reduced recurrence rates. But in addition to benets, some more problems have come in picture major being 'mesh infection'. Prolene mesh has shown promise when used in abdominal and inguinal hernia repair, especially when used in planned surgeries. Being a foreign material, slightest breach in asepsis can lead to favourable environment for bacterial proliferation and form a 'biolm'. It appears that laparoscopic hernia repair is a promising method but having chances of mesh infection owing to difcult approach and lack of uniformity in sterilization of laparoscopic instruments. Improper sterilization or protocols might lead to such a large ventral wall sinus or abscess increasing morbidity and cost of treatment. Case Report A 39 year old male patient presented to OPD with abdominal pain since 15 days, low grade fever , anorexia and weight loss 1.5 months following TAPP repair of bilateral inguinal hernia 1.5 months ago. Work-up showed acute diverticulitis with diverticula perforation involving descending colon and adjacent sigmoid colon in left iliac fossa with collection in left iliac fossa. Lower Midline Exploratory laparotomy was performed. Around 100 cc pus was drained around mesh beneath parietal peritoneum, the infected mesh was removed. Post operatively patient recovered excellently. TAPP is a safe procedure for treat groin hernias, unless, mesh complications Conclusion like foreign body reaction, deep-seated infection, mesh migration and perforation into viscera can occur even 20 years later of the procedure with no dened incidence. The chance of recurrence of hernia following management of infected mesh should always be considered
