UNLABELLED

Esophageal resection is still today associated with a high morbidity and mortality. Minimally invasive procedures show a significantly lower rate of such complications and therefore might also be associated with a lower surgical risk. However, publications till date contain little or no data on the extent of lymph node dissection. The aim of our study was to evaluate the morbidity and mortality rate of minimally invasive esophageal resection.

MATERIAL AND METHODS

In the last two years, we carried out 25 minimally invasive esophageal resections on five women and 20 men with a median age of 63 years (range 41-74 years). All data were accrued prospectively.

RESULTS

Nine patients were operated upon transhiatally and 12 combined laparocopic-thoracoscopic. On four patients, a thoracotomy was necessary. The average surgical time for the transhiatal approach was calculated at 164 minutes (range 150-180 min) and for the combined laparoscopic-thoracoscopic procedure 285 minutes (240-360 min). The thoracoscopic esophageal resection itself lasted 105 minutes on average; the last five resections each lasting 70 minutes. A median of 24,5 lymph nodes (19-26) was calculated in the laparoscopic-thoracoscopic technique. The transhiatal procedure revealed a median of 14 lymph nodes (12-17). Postoperatively, we had three cases of anastomotic and two cases of bronchial leakages, most probably associated with the use of monopolar current; complications no longer seen since usage of the HARMONIC ACE for surgical preparation. There was no 30 day letality.

CONCLUSION

Our experience with 25 successful minimally invasive esophageal resections shows that with increasing experience and better surgical equipment, the extent of lymph node dissection does not differ from open procedure.
