摘要

目的

食管癌是我国高发消化道恶性肿瘤，外科手术是其主要根治手段。充气式纵隔镜同步腹腔镜食管癌根治术逐步应用于食管癌外科治疗，消化道重建的胃塑形方式直接影响术后恢复与并发症发生，常规管状胃仍存在胸胃扩张、反流等问题，而锥形管状胃在此术式中的优劣尚不明确。本研究旨在比较常规管状胃和锥形管状胃在充气式纵隔镜同步腹腔镜食管癌根治术中的临床应用效果。

方法

采用单中心回顾性队列研究设计，纳入2023年1月至2025年1月在河南大学淮河医院胸外科行充气式纵隔镜同步腹腔镜食管癌根治术的患者共139例，根据临床实践中不同消化道重建方式分为常规管状胃组（77例）和锥形管状胃组（62例），所有患者均采用手工分层吻合，使用倾向性评分匹配（propensity score matching，PSM）对患者进行1∶1匹配。首要主要结局指标为术后并发症发生率，次要主要结局指标为术后主客观营养指标，次要结局指标包括炎症因子、胃肠功能指标及生活质量。

结果

经PSM匹配后，2组各纳入55例，匹配后患者基线资料比较，差异均无统计学意义（

0.05）。锥形管状胃组术后首次排气时间［（1.16±0.96）

（1.58±1.20）d，

=0.045］、首次经口进食时间［（4.43±2.10）

（5.48±2.98）d，

=0.035］显著短于常规管状胃组。锥形管状胃组胃食管反流（

=0.015）、胸胃扩张（

=0.026）发生率显著低于常规管状胃组，2组吻合口瘘、吻合口狭窄发生率无显著差异（均

0.05）。术后6个月随访提示，锥形管状胃组营养恢复更优，PG-

SGA评分显著更低（2.41±1.03

2.93±1.29，

=0.021），血清总蛋白、白蛋白、前白蛋白、血红蛋白等客观营养指标亦显著优于常规管状胃组（均

0.05）。次要结局指标中，术后1周锥形管状胃组炎症反应更轻微，IL-10［（7.85±0.61）

（8.47±0.65）ng/L，

0.001］、IL-6［（21.37±4.72）

（26.10±3.52）ng/L，

0.001］、TNF-α［（14.18±2.94）

（19.12±3.23）ng/L，

0.001］水平显著低于常规管状胃组。术后2周锥形管状胃组胃肠功能恢复更佳，MTL［（117.85±16.61）

（110.49±16.76）ng/L，

=0.023］、GAS［（62.58±15.72）

（55.12±16.11）ng/L，

=0.016］水平更高，术后6个月生活质量评估显示，锥形管状胃组生活质量评分显著更高（75.38±7.16

70.53±7.24，

0.05）。

结论

在充气式纵隔镜同步腹腔镜食管癌根治术中，相较于常规管状胃，锥形管状胃可显著改善患者术后胃肠功能，降低胸胃扩张、胃食管反流等并发症发生风险，改善术后营养状态并提升近期生活质量，具有临床应用价值。

Abstract

Objective

Esophageal cancer

a highly prevalent gastrointestinal malignancy in China

is primarily treated by surgical resection. Inflatable mediastinoscopy combined with laparoscopic esophagectomy has been gradually adopted in the surgical treatment for esophageal cancer. The gastric‑shaping strategy for digestive tract reconstruction directly affects postoperative recovery and complication occurrence. Conventional gastric tube reconstruction is still associated with problems such as intrathoracic gastric dilatation and gastroesophageal reflux

whereas the advantages and disadvantages of the coniform gastric tube in this surgical procedure remain unclear. This study aims to compare the clinical outcomes between conventional gastric tube and coniform gastric tube reconstruction after inflatable mediastinoscopy combined with laparoscopic esophagectomy.

Methods

A single-center retrospective cohort study was conducted on 139 patients who underwent inflatable mediastinoscopy combined with laparoscopic esophagectomy in Department of Thoracic Surgery of

Huaihe Hospital of Henan University between January 2023 and January 2025. According to different digestive tract reconstruction strategies

the patients were divided into a conventional gastric tube group (

=77) and a coniform gastric tube group (

=62). All patients received hand-sewn anastomosis. Propensity‑score matching (PSM) was performed at a 1∶1 ratio. The primary outcome was the incidence of postoperative complications

the secondary outcome was postoperative subjective and objective nutritional indicators

and secondary outcomes included inflammatory factors

gastrointestinal function indicators

and quality of life.

Results

After PSM

55 patients were included in each group

with no statistically significant differences in baseline characteristics between groups (all

0.05). The coniform gastric tube group demonstrated significantly shorter time to first postoperative flatus [(1.16±0.96)

(1.58±1.20) d

=0.045

]

and time to first oral intake [(4.43±2.10)

(5.48±2.98) d

=0.035

]

than the conventional gastric tube group. The incidences of gastroesophageal reflux (

=0.015) and intrathoracic gastric dilatation (

=0.026) were markedly lower in the coniform gastric tube group

whereas no significant intergroup differences were observed in the incidences of anastomotic leakage or anastomotic stricture (

0.05). At 6‑month postoperative follow‑up

better nutritional recovery was observed in the coniform gastric tube group

with significantly lower Patient-Generated Subjective Global Assessment (PG-SGA) scores (2.41±1.03

2.93±1.29

=0.021)

and objective nutritional indicators including serum total protein

albumin

prealbumin and hemoglobin were also significantly better than the conventional gastric tube group (all

0.05). For the secondary o

utcomes

the coniform gastric tube group exhibited milder inflammatory responses at 1 week postoperatively

with significantly lower levels of IL-10 [(7.85±0.61)

(8.47±0.65) ng/L

0.001

]

IL-6 [(21.37±4.72)

(26.10±3.52) ng/L

0.001

]

and TNF-α [(14.18±2.94)

(19.12±3.23) ng/L

0.001

]

. At 2 weeks postoperatively

gastrointestinal function recovery was obviously better in the coniform gastric tube group

with higher levels of motilin (MTL) [(117.85±16.61)

(110.49±16.76) ng/L

=0.023

]

and gastrin (GAS) [(62.58±15.72)

(55.12±16.11) ng/L

=0.016

]

. Quality of life assessment at 6 months postoperatively showed significantly higher scores in the coniform gastric tube group (75.38±7.16

70.53±7.24

0.05).

Conclusion

For patients undergoing inflatable mediastinoscopy combined with laparoscopic esophagectomy

coniform gastric tube reconstruction can effectively improve postoperative gastrointestinal function

reduce the risks of intrathoracic gastric dilatation and gastroesophageal reflux

promote postoperative nutritional status and enhance short‑term quality of life

demonstrating clinical application value.
