介绍一种腹腔镜减重手术中使用疝钩针配合乳胶管的改良肝悬吊技术，并评估其安全性及有效性。

回顾性分析了2021年10月至2023年6月在南通大学附属医院行腹腔镜减重手术的60名肥胖症患者的临床资料，根据术中是否使用该方法将所有的病例分为两组：研究组（n=20）与对照组（n=40）。其中研究组采用疝钩针配合乳胶管以悬吊肝脏，向左延伸的乳胶管的部分有足够的力量推动网膜以辅助暴露。对照组通过增加穿刺器由助手使用分叶状肝牵开器挑起肝脏。对比分析两组患者的肝酶变化水平、手术时长、术后C-反应蛋白（CRP）、术后住院时间、并发症发生情况等临床数据。

两组患者均顺利完成手术，无中转开放。研究组所有病例在术中均使用此法获得良好的手术暴露效果，其完成放置肝悬吊装置的时间为（160.2±37.6）s。通过比较两组间肝酶（ALT、AST）的变化情况以及术后CRP水平，并没有发现因使用此肝悬吊技术而造成明显的肝功能的损伤。相关并发症如肝包膜下血肿或肝脏撕裂，两组发生率分别为0/20 （0.0%）与3/40 （7.5%）。此外，该技术的使用未显著延长手术时长。两组间术后住院时间无明显差异。

疝钩针套入细乳胶管悬吊肝脏同时遮挡网膜的新方法安全且有效，适合腹腔镜下三孔或单孔袖状胃切除术，并可应用于其他的腹腔镜减重术式。

To introduce a modified liver retraction technique using a hernia needle grasper with a latex tube during laparoscopic bariatric surgery and evaluate its safety and effectiveness.

A retrospective study was conducted on the clinical data of 60 obese patients who underwent laparoscopic sleeve gastrectomy in Affiliated Hospital of Nantong University from October 2021 to June 2023. All cases were divided into two groups based on whether this method was used during the surgery: the study group (n=20) and the control group (n=40). In the study group, a hernia needle grasper with a latex tube was used to retract the liver, and the redundant part of the latex tube extending leftward had enough strength to push aside the residue omentum. In the control group, an additional trocar was made so the assistant could use a lobulated liver retractor to retract the liver. Clinical data such as changes in liver enzyme levels, the operating time, postoperative C-reactive protein (CRP), postoperative hospital stay, and complications were compared between the two groups.

All surgeries were completed without conversion. The study group achieved adequate exposure, and it took (160.2±37.6) seconds to finish the liver retracting technique. By comparing the changes in liver enzymes (ALT, AST) and postoperative CRP levels between the two groups, no significant liver function damage was found to be caused by the use of this liver retraction technique. The incidence of related complications such as subcapsular liver hematoma or liver laceration was 0/20 (0.0%) and 3/40 (7.5%) in the study and control groups. No significant differences were observed in operating time or postoperative hospital stay between the groups.

Using a hernia needle grasper with a latex tube for liver retraction while pushing aside the residue omentum is safe and effective. It is suitable for three-port or single-port laparoscopic sleeve gastrectomy and can be applied to other laparoscopic bariatric surgery.
