Inguinal hernia repair by laparoscopic surgeons: early experience and attitudes

Surgeon perceptions of Natural Orifice Translumenal Endoscopic Surgery (NOTES)

INTRODUCTION

If proven feasible and safe, Natural Orifice Translumenal Endoscopic Surgery (NOTES) would still need acceptance by surgeons if it were to become a mainstream approach.

METHODS

Three hundred fifty-seven surgeons responded to a preliminary survey describing NOTES and were asked to rate the importance of various surgical considerations and (assuming availability and safety) if they would choose to undergo and/or perform cholecystectomies by NOTES or laparoscopy and why.

RESULTS

The risk of having a complication was considered most important. NOTES was theorized to be riskier and to require greater skill than laparoscopy but to potentially cause less pain and convalescence. Nearly three-fourths (72%) of surgeons expressed interest in NOTES training which correlated with younger age, SAGES membership, minimally invasive surgery specialization, and flexible endoscopic volume. Forty-four percent would like to introduce NOTES cholecystectomy into their practices. Among those not preferring NOTES, 88% would adopt NOTES if data showed improved outcomes over laparoscopy. Finally, only 24% would choose to undergo cholecystectomy themselves by NOTES, believing it to be too new and riskier than laparoscopy.

DISCUSSION

The risk of having a complication is the greatest concern among surgeons, and safety will affect NOTES acceptance.

CONCLUSION

The results of this survey seem to justify more focused future investigations.

Antireflux surgery in the laparoscopic era

BACKGROUND

The recent development of laparoscopic techniques for fundoplication has created renewed interest in surgery for gastro-oesophageal reflux disease, leading to reports of large clinical series from many centres. However, controversy remains about technical aspects of laparoscopic antireflux surgery, with no consensus yet reached about a standard operative technique. It is important, therefore, to reassess critically the results of laparoscopic surgery for reflux disease, so that its current status can be determined.

METHODS

Published outcome studies for laparoscopic antireflux surgery, as well as selected studies from the era of open antireflux surgery, were reviewed to assess outcomes.

RESULTS

The results of case series for laparoscopic antireflux surgery with short- and medium-term follow-up, as well as the early results of randomized trials, confirm that this approach reduces the early overall morbidity of surgery for reflux disease. However, certain complications may be more common, for instance paraoesophageal hiatus herniation, pneumothorax and oesophageal perforation, requiring surgeons to use specific strategies which can help to avoid these problems. Published studies and trials do not support the routine or selective application of a posterior partial fundoplication technique or routine division of the short gastric vessels during Nissen fundoplication.

CONCLUSION

At present, a short loose Nissen fundoplication performed laparoscopically, with or without division of the short gastric vessels, is an appropriate surgical approach for gastro-oesophageal reflux disease. However, long-term outcomes following laparoscopic antireflux surgery will not be available for some years, and must be awaited before the final status of the various laparoscopic techniques can be confirmed.

Mesh hernioplasty using a stapler

BACKGROUND

The recent development of laparoscopic hernioplasty has evoked extensive re-examination of the safety and effectiveness of using synthetic mesh materials in hernia surgery. We have investigated the efficacy of anterior stapling mesh repair in the treatment of inguinal hernia.

METHODS

From July 1993 to June 1994, a modified open mesh hernioplasty using staples for anchorage has been performed in 127 patients.

RESULTS

The mean age of patients was 61.4 +/- 13.0 years. Over 90% of them were operated on under local anaesthesia. The operation time ranged from 30 to 95 min with a median of 39 min. Only sixteen patients (12.6%) required postoperative parenteral analgesics and the median time for resuming daily activities was 7 days. Apart from two patients with reactionary haemorrhage, there was no other significant complication observed. Only one recurrence was encountered over the 26-month median follow-up period.

CONCLUSIONS

We conclude that the modified mesh hernia repair with a stapling device is a feasible, inexpensive and safe procedure that is well tolerated under local anaesthesia by most patients.
