Summary

Totally laparoscopic total gastrectomy (TLTG) with a modified overlap method offers faster recovery and reduced pain compared to open total gastrectomy (OTG). Oncological outcomes and complication rates were similar between the two surgical approaches for gastric cancer.

Area of Science:

Surgical Oncology
Minimally Invasive Surgery
Gastrointestinal Surgery

Background:

The optimal anastomosis technique for laparoscopic total gastrectomy (LTG) remains undetermined despite various reported methods.
Establishing the best surgical approach for LTG is crucial for improving patient outcomes.

Purpose of the Study:

To compare the effectiveness and surgical outcomes of totally laparoscopic total gastrectomy (TLTG) using a modified overlap method against open total gastrectomy (OTG) with a circular stapled method.
To evaluate the safety and efficacy of different gastrectomy techniques for gastric cancer treatment.

Main Methods:

A comparative study involving 151 TLTG surgeries and 131 OTG surgeries for gastric cancer between March 2012 and December 2018.
Propensity score matching was employed to compare surgical and oncological outcomes, with subsequent analysis of risk factors for postoperative complications.

Main Results:

TLTG patients demonstrated earlier discharge (9.62 days vs. 13.51 days), faster return of bowel function, and reduced postoperative pain and opioid use compared to OTG patients.
No significant differences were observed in complication rates or 5-year survival between the TLTG and OTG groups.
Obesity (BMI) and higher American Society of Anaesthesiologists (ASA) scores were identified as independent risk factors for early complications, while age correlated with severe complications.

Conclusions:

TLTG with the modified overlap method provides comparable oncological results and complication rates to OTG, while offering benefits in terms of reduced pain, quicker recovery, and shorter hospital stays.
Careful surgical execution is advised for patients with obesity, high ASA scores, and advanced age undergoing total gastrectomy.
