Introduction:
Data on laparoscopic treatment of operable gastric cancer from India is sparse. This study aims to document outcomes of laparoscopic D2 gastrectomy in an Indian population.
Materials And Methods:
Data of patients who underwent laparoscopic D2 gastrectomy for operable advanced gastric cancer between February 2012 and January 2017 were collected from electronic hospital records supplemented by telephonic interviews and analyzed. Survival was evaluated using Kaplan-Meier survival analysis curves.
Results:
In total 121 patients were included. Conversion to open gastrectomy was 5.7%. One hundred and fourteen patients (73 laparoscopic subtotal gastrectomy and 41 laparoscopic total gastrectomy) were included for analysis. D2 lymphadenectomy was done in all cases; mean number of dissected lymph nodes was 23.12 ± 9.14 (12-45). Major complications (Clavien-Dindo Grade III and IV) was seen in 6.1% of cases with reoperation rate of 3.5% (4/114). Stage 3 disease was seen in 60.6% cases and stage 2 disease in 32.5%. Follow-up data were available for 76.3% of patients with mean follow-up of 29.5 months. Overall survival across all stages was 38.7 months. Five-year disease-free survival and overall survival were 36.7% and 55.9% respectively, across all stages.
Conclusion:
Laparoscopic D2 gastrectomy is safe, feasible with similar postoperative complications and comparable survival outcomes across all stages when compared to available literature on open gastrectomy cases.
