We investigated whether the standardized "can-opener method" surgical technique is an adequate surgical procedure for hemispheric hepatectomy in segments 7 and 8.
Forty-two patients who underwent laparoscopic hemispheric liver resection for segments 7 and 8 using our standardized surgical technique were enrolled. To examine the effect of this standardized surgical procedure on short-term outcomes, patients were classified into two groups based on the timing of the standardization of their procedures (Group A, the first half of the cases, and Group B, the second half of the cases). Short-term outcomes were subsequently compared between the two groups.
Significant differences in operation time (465 min vs. 332 min, = 0.001), intraoperative blood loss volume (645 g vs. 105 g, = 0.011), postoperative complications (Clavien‒Dindo Grade I and Grade II) (7 vs. 1, = 0.011), and length of postoperative hospital stay (10 days vs. 7 days, = 0.001) were detected between the two groups. All patients had negative surgical margins. With respect to postoperative complications, four patients had Grade I complications, such as wound infection and minor pneumonia, and four patients had Grade II complications, such as bile duct infection and intra-abdominal abscess. No patients experienced 90-day mortality.
Our standardized surgical technique is an adequate surgical procedure for hemispheric hepatectomy in segments 7 and 8 and is referred to as the "can-opener method".
我们研究了标准化的“开罐器法”手术技术是否是用于7段和8段肝半球切除术的合适手术方法。
纳入42例采用我们的标准化手术技术行7段和8段腹腔镜肝半球切除术的患者。为了检验这种标准化手术方法对短期结局的影响，根据手术标准化的时间将患者分为两组（A组，前半部分病例；B组，后半部分病例）。随后比较两组的短期结局。
两组在手术时间（465分钟对332分钟，P = 0.001）、术中失血量（645克对105克，P = 0.011）、术后并发症（Clavien-Dindo I级和II级）（7例对1例，P = 0.011）以及术后住院时间（10天对7天，P = 0.001）方面存在显著差异。所有患者手术切缘均为阴性。关于术后并发症，4例患者发生I级并发症，如伤口感染和轻度肺炎，4例患者发生II级并发症，如胆管感染和腹腔内脓肿。无患者发生90天死亡率。
我们的标准化手术技术是用于7段和8段肝半球切除术的合适手术方法，被称为“开罐器法”。
