Title: Comparison of short-term efficacy of laparoscopic proximal gastrectomy with modified
side overlap anastomosis and laparoscopic total gastrectomy with Roux-en-Y anastomosis
Version: 2 Date: 26 Jan 2025
Reviewer's report:
This manuscript compared the laparoscopic proximal gastrectomy (LPG) with modified side
overlap anastomosis and laparoscopic total gastrectomy (LTG) with Roux-en-Y anastomosis
for upper gastric adenocarcinoma. It is an interesting technique that intends to reduce the
postoperative GERD after proximal gastrectomy. The comments are listed as follows:
1, Please check the manuscript to avoid some language errors. For example, line 5-6:The
clinicopathological data of 262 patients who underwent LPG or LTG for upper gastric
adenocarcinoma from January 2016 to December 2022 were collected. missing LTG.  Table 3,
wrong placement of  Digestive tract reconstruction duration (min) and Total surgery duration
(min)
2, Though Propensity Score Matching could significantly decrease the bias, the number of the
patients included in this study was too small to draw an solid conclusion. And the method of
PMS should be further elaborated.
3, The author used GERD scale scores and gastroscopy to evaluate the post-op GERD.  Though
they are very useful for the diagnosis of GERD, 24h pH test remains the golden standard for
GERD diagnosis. BTW, what is the reason for the LAB esophagitis after LTG? What about the
PPI usage after surgery? which score system did you use? GerdQ? RDQ?
4, For the nutritional evaluation, Though NRS2002 is good. Anemia, multivitamin
supplementation and other items should be added. And it is better to include the score for quality
of life evaluation such as SF-36.
5, Though your figures were well drawn. I would suggest to put a video or real surgical
screenshot in the manuscript.
