Colonoscopic removal of inguinal hernia mesh: report of a case and literature review

The transabdominal preperitoneal (TAPP) procedure for laparoscopic inguinal hernia mesh repair is being applied with increasing frequency. This technique has an acceptable recurrence rate (0.4-3.9%), but has varying complication rates (1.3-17.4%).1,2 We report the first case of mesh penetration of the colon following laparoscopic TAPP repair, treated with colonoscopy.

Totally extraperitoneal inguinal hernioplasty with titanium-coated lightweight polypropylene mesh: early results

BACKGROUND

This prospective study of a new titanium-coated low-weight polypropylene (PP) mesh (16 g PP/m2) was designed to investigate the clinical efficacy and safety of totally extraperitoneal endoscopic hernioplasty (TEP).

METHODS

In this study, 400 patients (average age, 53.5 years; range, 19-80 years) with a total of 588 inguinal hernias underwent surgery with the TEP technique between September 2002 and October 2003. Of these patients, 12.4% had experienced recurrent hernias after open suture herniotomy. In 92% of the cases (368 patients with 540 hernias), a lightweight (16 g PP/m2) titanium-coated polypropylene mesh was implanted without fixation, and in 8% (32 patients with 48 hernias) an identical medium-weight (35 g PP/m2) mesh was implanted. The first follow-up examination was scheduled for postoperative week 6.

RESULTS

In the lightweight mesh group, the mean group, operating time per patient was 61 min, corresponding to a calculated time per hernia of 41 min. Two intraoperative major complications occurred: an injury to the cecum and an injury to the bladder. In 12 cases (2%), bleeding from epigastric, testicular, or pubic bone vessels was observed. No injuries to pelvic vessels were seen. One patient was underwent an endoscopic revision to deal with an anticoagulation-related bleed. The mortality rate was 0%. In 12 patients, postoperative hematomas developed. One preperitoneal lipoma had to be extirpated. No infections of the mesh occurred. The median follow-up period for 371 patients (92.3%) was 7.2 weeks (range, 4-14 weeks). These 343 patients (with 504 hernias) had been provided with a lightweight titanium-coated polypropylene mesh (16 g PP/m2) (follow-up rate, 93.2%). Of these patients, 3.5% reported persistent ingunial pain, 1.7% described a sensation of rigidity in the region of the groin, and 3.2% reported dysesthesia. The early recurrence rate was 0.2%.

CONCLUSIONS

The TEP procedure can be performed safely and effectively with the appreciably material-reduced and titanium-coated polypropylene mesh without the need for fixation of the implant. The low early recurrence rate of 0.2% is evidence that the posterior wall of the inguinal canal is adequately augmented. The question whether the material reduction and the titanium coating of the mesh may bring about a reduction in postoperative chronic pain and the sensation of rigidity in the inguinal area via an improvement in biocompatibility must await the results of the scheduled follow-up examination 1 year after the surgical procedure.

Recurrent inguinal hernia: a ten-year review

BACKGROUND

This study evaluates the results obtained in recurrent inguinal hernia repair over the past ten years in a general hospital using laparoscopic (LAP) and open tension-free mesh (Lichtenstein) procedures.

METHODS

A prospective controlled study with 258 recurrent inguinal hernias in 235 patients over a ten-year period. The main outcome measurements were recurrence rate, operating time, hospital stay, postoperative complications, and cost.

RESULTS

There were 10 recurrences (4.3%): 7 in the Lichtenstein group (5.7%) and 3 (2.2%) in the LAP group (P = nonsignificant [NS]). There were 15 (12.2%) postoperative complications in the Lichtenstein group and 6 (4.4%) in the LAP group (P =0.04). The operating room costs were higher in the LAP group, but this difference was offset by a significantly shorter hospital stay, shorter operating time, and earlier return to work.

CONCLUSION

Laparoscopic repair is an effective option for the treatment of recurrent inguinal hernia. The TEP approach combines the advantages of minimal invasive surgery and those of tension-free mesh repair, reducing operating time, postoperative morbidity, and recurrence rate.
