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

Area of Science:

• Gastroenterology
• Surgical Oncology
• Oncology

Background:

• Gastric cancer surgery requires balancing oncological safety with postoperative quality of life.
• Minimally invasive techniques like laparoscopic surgery aim to improve patient recovery.
• Pylorus-preserving gastrectomy offers potential benefits over traditional distal gastrectomy.

Purpose of the Study:

• To compare the postoperative nutritional status and long-term outcomes of laparoscopic-assisted pylorus-preserving gastrectomy (LAPPG) versus laparoscopic-assisted distal gastrectomy (LADG).

Main Methods:

• Retrospective review of 83 gastric cancer patients undergoing either LAPPG or LADG between 2010 and 2019.
• Evaluation of postoperative nutritional status, focusing on weight loss rates at 1, 6, 12, and 24 months.
• Assessment of long-term outcomes including recurrence and overall survival rates.

Main Results:

• Patients undergoing LAPPG experienced significantly less weight loss at 6, 12, and 24 months post-surgery compared to LADG.
• No recurrence was observed in either group within 5 years.
• The 5-year overall survival rate for Stage I cancer patients was higher in the LAPPG group (100%) than in the LADG group (82.9%).
• The LADG group had 6 deaths from other causes, while the LAPPG group had none.

Conclusions:

• LAPPG is associated with significantly lower postoperative weight loss than LADG.
• LAPPG demonstrates a favorable long-term prognosis, potentially reducing mortality from other diseases like pneumonia.
