Summary
Laparoscopic gastrectomy offers comparable short-term and long-term outcomes to open surgery for advanced gastric cancer. This minimally invasive approach demonstrates oncological feasibility and technical safety in patients with D2 lymphadenectomy.
Area of Science:
- Surgical Oncology
- Gastrointestinal Surgery
- Minimally Invasive Surgery
Background:
- Advanced gastric cancer presents significant treatment challenges.
- D2 lymphadenectomy is a standard oncological procedure for gastric cancer.
- Evaluating minimally invasive techniques is crucial for improving patient outcomes.
Purpose of the Study:
- To assess the oncological feasibility and technical safety of laparoscopic gastrectomy with D2 lymphadenectomy for advanced gastric cancer.
- To compare short-term and long-term outcomes of laparoscopic versus open gastrectomy.
Main Methods:
- Retrospective analysis of 186 advanced gastric cancer patients undergoing gastrectomy with D2 lymphadenectomy.
- Inclusion criteria: invasion into muscularis propria, subserosa, or serosa (without distant organ involvement), stages N0-2, M0.
- Comparison of postoperative morbidity, overall survival, and recurrence-free survival between laparoscopic and open gastrectomy groups.
Main Results:
- No significant difference in postoperative morbidity for distal or total gastrectomy between laparoscopic and open approaches.
- No deaths reported in any group.
- No statistically significant differences in overall survival or recurrence-free survival between laparoscopic and open groups across various clinical and pathological stages.
Conclusions:
- Laparoscopic gastrectomy with D2 lymphadenectomy is oncologically feasible and technically safe for advanced gastric cancer.
- Outcomes, including survival rates, are comparable to open gastrectomy.
- Laparoscopic surgery presents a favorable alternative for selected advanced gastric cancer patients.

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

16.2K
Directional terms are essential for describing the relative locations of different body structures. For instance, an anatomist might describe one band of tissue as "inferior to" another, or a physician might describe a tumor as "superficial to" a deeper body structure. These terms often use comparative terms in pairs to trace out the relative locations of one body part to another or descriptions of body tissues like the deeper ones from superficially present with reference to...

Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...
