- W4366353485 abstract "Objective: We aimed to explore the feasibility of a single-port thoracoscopy- assisted five-step laparoscopic procedure via transabdominal diaphragmatic(TD) approach(abbreviated as five-step maneuver) for No.111 lymphadenectomy in patients with Siewert type II esophageal gastric junction adenocarcinoma (AEG). Methods: This was a descriptive case series study. The inclusion criteria were as follows: (1) age 18-80 years; (2) diagnosis of Siewert type II AEG; (3) clinical tumor stage cT2-4aNanyM0; (4) meeting indications of the transthoracic single-port assisted laparoscopic five-step procedure incorporating lower mediastinal lymph node dissection via a TD approach; (5) Eastern Cooperative Oncology Group performance status (ECOG PS) 0-1; and (6) American Society of Anesthesiologists classification I, II, or III. The exclusion criteria included previous esophageal or gastric surgery, other cancers within the previous 5 years, pregnancy or lactation, and serious medical conditions. We retrospectively collected and analyzed the clinical data of 17 patients (age [mean ± SD], [63.6±11.9] years; and 12 men) who met the inclusion criteria in the Guangdong Provincial Hospital of Chinese Medicine from January 2022 to September 2022. No.111 lymphadenectomy was performed using five-step maneuver as follows: superior to the diaphragm, starting caudad to the pericardium, along the direction of the cardio-phrenic angle and ending at the upper part of the cardio-phrenic angle, right to the right pleura and left to the fibrous pericardium , completely exposing the cardio-phrenic angle. The primary outcome includes the numbers of harvested and of positive No.111 lymph nodes. Results: Seventeen patients (3 proximal gastrectomy and 14 total gastrectomy) had undergone the five-step maneuver including lower mediastinal lymphadenectomy without conversion to laparotomy or thoracotomy and all had achieved R0 resection with no perioperative deaths. The total operative time was (268.2±32.9) minutes, and the lower mediastinal lymph node dissection time was (34.0±6.0) minutes. The median estimated blood loss was 50 (20-350) ml. A median of 7 (2-17) mediastinal lymph nodes and 2(0-6) No. 111 lymph nodes were harvested. No. 111 lymph node metastasis was identified in 1 patient. The time to first flatus occurred 3 (2-4) days postoperatively and thoracic drainage was used for 7 (4-15) days. The median postoperative hospital stay was 9 (6-16) days. One patient had a chylous fistula that resolved with conservative treatment. No serious complications occurred in any patient. Conclusion: The single-port thoracoscopy-assisted five-step laparoscopic procedure via a TD approach can facilitate No. 111 lymphadenectomy with few complications.目的: 探索胸腔单孔辅助腹腔镜经腹膈肌入路“五步法”下纵隔淋巴结清扫术(简称为“五步法”)对SiewertⅡ型食管胃结合部腺癌(AEG)No.111淋巴结清扫的效果。 方法: 本研究采用描述性病例系列研究方法。纳入标准:(1)年龄18~80岁;(2)术前确诊为SiewertⅡ型AEG;(3)术前临床分期为进展期AEG(cT2~4aNanyM0);(4)适用于胸腔单孔辅助腹腔镜经腹膈肌入路“五步法”下纵隔淋巴结清扫术;(5)术前美国东部肿瘤协作组(ECOG)体力状态评分为0或1分;(6)美国麻醉医师协会评分(ASA)Ⅰ~Ⅲ级。排除有食管及胃部手术史、5年内有其他恶性肿瘤病史、妊娠或哺乳期妇女以及患有严重精神疾病患者。根据上述标准,回顾性收集2022年1—9月在广东省中医院接受胸腔单孔辅助腹腔镜经腹膈肌入路“五步法”下纵隔淋巴结清扫术的17例SiewertⅡ型AEG患者的临床资料,其中男性12例,年龄(63.6±11.9)岁。“五步法”中No.111淋巴结清扫方式为:在膈肌上方,由心包底部开始,沿心膈角方向,终点清扫至心膈角顶端,右侧界清扫至右侧胸膜,左侧界为心包膈部,将心膈角完整显露。主要观察指标为No.111淋巴结的清扫数目及阳性例数。 结果: 17例患者均顺利完成“五步法”下纵隔淋巴结清扫术,均达到R0切除,无中转开腹开胸,无围手术期死亡。其中3例患者行近端胃切除术,14例患者行全胃切除术。全组手术时间为(268.2±32.9)min,下纵隔淋巴结清扫时间为(34.0±6.0)min,术中出血量为50(20~350)ml。下纵隔淋巴结清扫数目为7(2~17)枚,No.111淋巴结的清扫数目为2(0~6)枚,其中No.111淋巴结阳性1例。术后首次排气时间为3(2~4)d,胸腔引流管留置时间为7(4~15)d,住院时间为9(6~16)d。1例患者术后出现乳糜漏,保守治疗后痊愈。无患者出现严重并发症。 结论: 胸腔单孔辅助腹腔镜经腹膈肌入路“五步法”下纵隔淋巴结清扫术有助于实现No.111淋巴结的彻底清扫,并发症风险低。." @default.
