Laparoscopic gastrectomy for gastric cancer.
BACKGROUND
Surgery in gastric cancer (GC) aims to achieve resection of the primary tumor and its lymphatic drain, with a minimal adverse effect on morbidity and mortality, and the best possible quality of life.


METHODS
From June 1993 to May 2008, 113 patients with a preoperative diagnosis of the GC were considered for laparoscopic gastrectomy at our institution. There was a predominance of males and mean age was 60 years. After peritoneal cavity inspection, laparoscopic ultrasound was used to determine the presence of deep liver metastasis. Total gastrectomy and Roux-en-Y reconstruction were performed in upper and middle-third tumors, and subtotal gastrectomy, either with Billroth II or Roux-en-Y reconstruction, in tumors affecting the lower third of the stomach. D2 lymphadenectomy was performed in both cases.


RESULTS
There were 21 cases (18.5%) with distant metastases and/or an unresectable tumor due to the invasion of adjacent organs. In these patients the procedure was limited to laparoscopic biopsy in 16 cases and laparoscopic gastrojejunostomy in 5 cases. Laparoscopic gastrectomy was performed in 92 patients with a mean surgical time of 162 minutes and a mortality rate of 5.4%. Conversion was necessary in 7 cases (7.6%).


CONCLUSIONS
The benefits and safety of laparoscopic gastrectomy are evident, with similar outcomes to conventional surgery and all the advantages of minimally invasive access. The learning curve is long. Laparoscopic gastrectomy is a safe and effective option for the treatment of GC, avoiding nontherapeutic laparotomy in patients with advanced disease. Comparative prospective studies evaluating the long-term survival of these patients are still necessary.
