Laparoscopic surgery is a minimally invasive surgery; however, obstacles to its functional optimization remain. Surgical ports can accommodate only one instrument at a time so complex exchange manipulations are necessary during surgery which increases operation times and patient risk. We developed a new laparoscopic instrument that functions as both forceps and a suction tube, which renders intraoperative tool exchange unnecessary. This pilot study was undertaken to evaluate the safety and efficacy of this novel dual-function device in laparoscopic surgery for gastric cancer.
This single-center pilot study assessed patient safety during and after laparoscopic distal gastrectomy for gastric cancer with the suction-forceps using intraoperative video and clinical follow-up, respectively. To evaluate instrument efficacy, we measured the time interval between the start of any bleeding and the start of aspiration ("suction access time") and compared this time with that of a conventional surgical setup.
In total 15 patients participated, with all procedures being successful. No excess tissue damage occurred during surgery. Suction access time was significantly shorter in cases of bleeding when the suction-tip forceps were used for aspiration (2.01 seconds) compared to an ordinary suction tube (12.5 seconds; P < .01).
These findings suggest that our new suction-tip forceps are a useful, safe, and efficacious operative tool. This surgical innovation may considerably simplify gastric laparoscopic surgery. This pilot study was registered with Japan Clinical Trial Registration on 22 June 2017 (registration number: UMIN000027879).
腹腔镜手术是一种微创手术，但在功能优化方面仍存在障碍。手术端口一次只能容纳一个器械，因此在手术过程中需要进行复杂的器械交换操作，这会增加手术时间和患者风险。我们开发了一种新型的腹腔镜器械，它既可以作为钳子，也可以作为吸引管，从而无需在术中进行器械交换。这项初步研究旨在评估该新型双功能器械在胃癌腹腔镜手术中的安全性和有效性。
本单中心初步研究通过术中录像和临床随访，分别评估了使用吸引夹进行腹腔镜远端胃癌根治术期间和之后患者的安全性。为了评估器械的疗效，我们测量了从任何出血开始到开始吸引的时间间隔（“吸引进入时间”），并将该时间与常规手术设置进行了比较。
共有 15 名患者参与了本研究，所有手术均成功完成。手术过程中没有发生额外的组织损伤。在使用吸引夹进行吸引的情况下，出血时的吸引进入时间明显短于使用普通吸引管（2.01 秒）（P<.01）。
这些发现表明，我们的新型带吸引头的钳子是一种有用、安全、有效的手术工具。这种手术创新可以极大地简化腹腔镜胃手术。本初步研究于 2017 年 6 月 22 日在日本临床试验注册处注册（注册号：UMIN000027879）。
