An inguinal hernia of a third kind?

Inguinal hernias are classified anatomically into indirect and direct types. We illustrate two cases of an inguinal hernia where the defect was demonstrated to lie between the deep ring and the inferior epigastric vessels, therefore, not fitting the standard criteria for either direct or indirect inguinal hernias. Taking this into account, we propose that the hernia which we describe should either be considered as a completely new type of inguinal hernia or, alternatively, all of the currently accepted classifications should be changed or adapted to incorporate it.     

Robotic inguinal hernia repair: Is it a new era in the management of inguinal hernia?

ObjectiveWe compared outcomes of elective inguinal hernia repair performed at one institution by three approaches: robotic-assistance, laparoscopic, and open.MethodsCharacteristics of the patients, the hernia and the procedures performed during 2014–2016 were accessed from patient electronic medical files of 137 elective inguinal hernia repairs. 24 surgeries were robotic-assisted, 16 laparoscopic and 97 open repairs.ResultsDistributions of age, sex and BMI did not differ between the groups. Bilateral repair was more common in the robotic (70.8%) than the laparoscopic (50.0%) and open groups (12.4%) (p < 0.001). Direct hernias were more common in the open (45.4%) than the robotic (20.8%) and laparoscopic (12.5%) groups (p < 0.001). Only 3 hernias were inguinoscrotal, all in the robotic group. The median operation times were 44.0, 79.0 and 92.5 min for the open, laparoscopic and robotic methods, respectively (p < 0.001). Among the unilateral repairs, the median operative times were the same for the robotic and laparoscopic procedures, 73 min, and less for the open procedures, 40 min. The proportion of patients hospitalized for 2–3 days was higher for open repair (13.4% vs. 6.2% and 0% for laparoscopic and robotic), but this difference was not statistically significant. The median maximal postoperative pain according to a 0-10-point visual analogue score was 5.0, 2.0 and 0 for open, laparoscopic and robotic procedures, respectively (p < 0.001).ConclusionsThis report demonstrated the safety and feasibility of robotic-assisted inguinal hernia repair.     

Laparoscopic hernia repair – the facts, but no fashion

Background: For about 10 years now, laparoscopic hernia surgery has been introduced as an additional mode of therapy in the treatment of inguinal hernias. This method is being reproached with higher costs of surgery and rate of complications, as well as missing long-term results. Materials and methods: Within a literature research, data from 25 randomised trials and 16 prospective observational studies on endoscopic and conventional hernia surgery were evaluated. Statistics were calculated using the chi² test. Results: Compared with the conventional suture technique and tension-free surgery, the endoscopic repair proved to be advantageous with regard to postoperative pain and period of disablement. There was no significant difference between the methods when evaluating the rate of complications. In two randomised trials, there was a significant difference in favour of endoscopic repair with regard to the recurrence rates, whereas in the other studies a significant difference could not be shown. In the prospective series, recurrence rates were 0.71% for totally preperitoneal repair (TEP) and 1.06% for transabdominal preperitoneal repair (TAPP) repair. Conclusion: Endoscopic hernia surgery (TAPP and TEP) represents an efficient method of treatment in the therapy of inguinal hernias. Recurrent and bilateral hernias can be seen as an absolute indication for endoscopic repair. Received: 14 December 1998 Accepted: 29 March 1999     

Is minilaparoscopic inguinal hernia repair feasible? A preliminary experience

INTRODUCTION: Laparoscopy has rapidly emerged as the preferred surgical approach to a number of different diseases because it allows for a correct diagnosis and proper treatment. It seems to be moving toward the use of mini-instruments (5 mm or less in diameter). The aim of this paper is to illustrate retrospectively the results of an initial experience of minilaparoscopic transabdominal preperitoneal (miniTAPP) repair of groin hernia defects performed at two institutions. MATERIALS AND METHODS: Between February 2000 and December 2003, a total of 303 patients (mean age, 45 years) underwent a miniTAPP procedure: 213 patients (70.2%) were operated on bilaterally and 90 (28.7%) for a unilateral defect, with a total of 516 hernia defects repaired. The primary endpoint was the feasibility rate for miniTAPP. The secondary endpoint was the incidence of mini-TAPP-related complications. RESULTS: No conversions to laparoscopy or an anterior open approach were required. There were no major complications, while minor complications ranged as high as 0.3%. CONCLUSION: While limited by its retrospective design, the present study indicates that the minilaparoscopic approach to groin hernia repair is safe and effective, making miniTAPP a challenging alternative to laparoscopy in the approach to groin hernia repair.     

Bilateral inguinal hernia repair: laparoscopic or open approach?

Background  

The aim of this study was to investigate outcomes in the treatment of bilateral inguinal hernia, comparing the laparoscopic totally extraperitoneal (TEP) and open tension-free mesh repair (LICHT) approaches.     

Are there any predictive factors of metachronous inguinal hernias in children with unilateral inguinal hernia?

Purpose  

This study was done to identify risk factors for metachronous manifestation of contralateral inguinal hernia in children with unilateral inguinal hernia.     

Open or laparoscopic preperitoneal mesh repair for recurrent inguinal hernia?

Background: Giant prosthetic reinforcement of the visceral sac (GPRVS), an open preperitoneal mesh repair, is a very effective groin hernia repair. Laparoscopic transabdominal preperitoneal repair (TAPP), based on the same principle, is expected to combine low recurrence rates with minimal postoperation morbidity. Methods: Seventy-nine patients with 93 recurrent and 15 concomitant primary inguinal hernias were randomized between GPRVS (37 patients) and TAPP (42 patients). Operating time, complications, pain, analgesia use, disability period, and recurrences were recorded. Results: Mean operating time was 56 min with GPRVS versus 79 min with TAPP (p < 0.001). Most complications were minor, except for a pulmonary embolus and an ileus, both after GPRVS. Patients experienced less pain after a laparoscopic repair. Average disability period was 23 days with GPRVS versus 13 days with TAPP (p= 0.03) for work, and 29 versus 21 days, respectively (p= 0.07) for physical activities. Recurrence rates at a mean follow-up of 34 months were 1 in 52 (1.9%) for GPRVS versus 7 in 56 (12.5%) for TAPP (p= 0.04). Hospital costs in U.S. dollars were comparable, with GPRVS at $1,150 and TAPP at $1,179. Conclusions: Laparoscopic repair of recurrent inguinal hernia has a lower morbidity than GPRVS. However, laparoscopic repair is a difficult operation, and the potential technical failure rate is higher. With regard to recurrence rates, the open preperitoneal prosthetic mesh repair remains the best repair. Received: 14 April 1998/Accepted: 28 May 1998
