Abstract

BACKGROUND

: Bariatric surgery is currently the most effective method to ameliorate co-morbidities as consequence of morbidly obese patients with BMI over 35 kg/m2. Endoscopic techniques have been developed to treat patients with mild obesity and ameliorate comorbidities, but endoscopic skills are needed, beside the costs of the devices.

AIM

: To report a new technique for internal gastric plication using an intragastric single port device in an experimental swine model.

METHODS

: Twenty experiments using fresh pig cadaver stomachs in a laparoscopic trainer were performed. The procedure was performed as follow in ten pigs: 1) volume measure; 2) insufflation of the stomach with CO2; 3) extroversion of the stomach through the simulator and installation of the single port device (Gelpoint Applied Mini) through a gastrotomy close to the pylorus; 4) performance of four intragastric handsewn 4-point sutures with Prolene 2-0, from the gastric fundus to the antrum; 5) after the performance, the residual volume was measured. Sleeve gastrectomy was also performed in further ten pigs and pre- and post-procedure gastric volume were measured.

RESULTS

: The internal gastric plication technique was performed successfully in the ten swine experiments. The mean procedure time was 27±4 min. It produced a reduction of gastric volume of a mean of 51%, and sleeve gastrectomy, a mean of 90% in this swine model.

CONCLUSION

: The internal gastric plication technique using an intragastric single port device required few skills to perform, had low operative time and achieved good reduction (51%) of gastric volume in an in vitro experimental model.

RACIONAL

: A cirurgia bariátrica é atualmente o método mais efetivo para melhorar as co-morbidades decorrentes da obesidade mórbida com IMC acima de 35 kg/m2. Técnicas endoscópicas foram desenvolvidas para tratar pacientes com obesidade leve e melhorar as comorbidades, mas habilidades endoscópicas são necessárias, além dos custos.

OBJETIVO

: Relatar uma nova técnica para a plicatura gástrica interna utilizando um dispositivo intragástrico de portal único em modelo experimental de suínos.

MÉTODOS:: Foram realizados 20 experimentos utilizando estômagos de cadáver de porco fresco em um instrutor laparoscópico. O procedimento foi realizado da seguinte forma em dez porcos: 1) medida de volume; 2) insuflação do estômago com CO2; 3) extroversão do estômago através do simulador e instalação do dispositivo de uma única via (Gelpoint Applied Mini) através de uma gastrotomia próxima ao piloro; 4) realização de quatro suturas de quatro pontos intra-gástricas com Prolene 2-0, desde o fundo gástrico até o antro; 5) medição do volume residual. A gastrectomia vertical foi também realizada em mais dez suínos e o volume gástrico pré e pós-procedimento foi medido.

RESULTADOS

: A técnica de plicatura gástrica interna foi realizada com sucesso nos dez experimentos com suínos. O tempo médio do procedimento foi de 27±4 min. Produziu redução do volume gástrico em média de 51%, e a gastrectomia vertical em média de 90% neste modelo suíno.

CONCLUSÃO:: A técnica de plicatura gástrica interna, utilizando um dispositivo intragástrico de uma única via, exigiu poucas habilidades para ser realizada, teve baixo tempo operatório e obteve boa redução (51%) do volume gástrico em um modelo experimental in vitro.

摘要

背景

减重手术目前是改善体重指数超过35kg/m²的病态肥胖患者合并症的最有效方法。已经开发出内镜技术来治疗轻度肥胖患者并改善合并症,但除了设备成本外,还需要内镜技术。

目的

报告一种在实验猪模型中使用胃内单端口装置进行胃内折叠的新技术。

方法

在腹腔镜训练器中使用新鲜猪尸体胃进行了20次实验。在10头猪中按以下步骤进行该手术:1)测量体积;2)用二氧化碳给胃充气;3)将胃通过模拟器外翻,并通过靠近幽门的胃切开术安装单端口装置(Gelpoint Applied Mini);4)用2-0普罗伦缝线从胃底到胃窦进行4针胃内手工缝合;5)手术后测量残余体积。另外10头猪也进行了袖状胃切除术,并测量了手术前后的胃体积。

结果

在10头猪的实验中成功进行了胃内折叠技术。平均手术时间为27±4分钟。在该猪模型中,它使胃体积平均减少了51%,袖状胃切除术使胃体积平均减少了90%。

结论

使用胃内单端口装置的胃内折叠技术操作所需技能少,手术时间短,并且在体外实验模型中实现了胃体积的良好减少(51%)。

合理说明

减重手术目前是改善病态肥胖(体重指数超过35kg/m²)相关合并症的最有效方法。已开发内镜技术治疗轻度肥胖患者并改善合并症,但除成本外还需要内镜技术。

目的

报告一种在实验猪模型中使用胃内单端口装置进行胃内折叠的新技术。

方法

在腹腔镜训练器中使用新鲜猪尸体胃进行20次实验。在10头猪中按以下方式进行手术:1)测量体积;2)用二氧化碳给胃充气;3)将胃通过模拟器外翻,并通过靠近幽门的胃切开术安装单通道装置(Gelpoint Applied Mini);4)用2-0普罗伦缝线从胃底到胃窦进行4针胃内缝合;5)测量残余体积。另外10头猪也进行了垂直胃切除术,并测量了手术前后的胃体积。

结果

在10头猪的实验中成功进行了胃内折叠技术。平均手术时间为27±4分钟。在该猪模型中,它使胃体积平均减少了51%,垂直胃切除术使胃体积平均减少了90%。

结论

使用胃内单通道装置的胃内折叠技术操作所需技能少,手术时间短,并且在体外实验模型中实现了胃体积的良好减少(51%)。
