[Nutritional Status after Laparoscopic-Assisted Pylorus-Preserving Gastrectomy].

PATIENTS AND

METHODS

Patients with gastric cancer who underwent laparoscopic-assisted pylorus-preserving gastrectomy (LAPPG group)or laparoscopic-assisted distal gastrectomy(LADG group)between January 2010 and December 2019 were reviewed and their postoperative nutritional status and long-term outcomes retrospectively evaluated.

RESULTS

In total, 83 patients(LAPPG group, n=23; LADG group, n=60)were included. Weight loss rates 1, 6, 12, and 24 months postoperatively in the LAPPG and LADG groups were 5.7% and 7.1%, 6.6% and 9.6%, 5.8% and 10.1%, and 5.2% and 8.7%, respectively. The LADG group exhibited a significantly higher weight loss than the LAPPG group at 6, 12, and 24 months (p=0.007, 0.002, and 0.022, respectively). No recurrence was observed in either group within 5 years of surgery. The 5- year overall survival rate of patients with pathological Stage Ⅰ cancer( LAPPG group, n=23, LADG group, n=51) was higher in the LAPPG group than in the LADG group(100% vs 82.9%, p=0.027). There were 6 cases of death from other diseases in the LADG group(pneumonia, n=2, other cancer, n=2, postoperative bleeding, n=1, and heart failure, n=1)but none in the LAPPG group.

CONCLUSION

The weight loss after LAPPG was significantly lower than that after LADG. Furthermore, the former showed a good prognosis without death from other diseases, such as pneumonia.
