  • 摘要: 目的 探讨锥形管状胃联合颈部端端分层吻合在胸腹腔镜食管癌切除术中的应用价值。方法 采用回顾性描述性研究方法。收集2016年12月至2017年12月四川大学华西医院收治的122例食管癌患者的临床病理资料;男89例,女33例;年龄为(61±8)岁,年龄范围为48~81岁。患者均行腹腔镜McKeown三切口食管癌切除术,采用全腔镜下游离食管及胃、左颈部胃食管端端手工分层吻合。观察指标:(1)手术治疗情况。(2)术后并发症情况。(3)随访情况。采用门诊方式随访,术后1、3、6个月及1年门诊随访。了解患者术后反流、吻合口狭窄、吻合口宽度评估情况。随访时间截至2018年12月。正态分布的计量资料以Mean±SD表示;偏态分布的计量资料以M(P25,P75)或M(范围)表示。计数资料以绝对数表示。结果 (1)手术治疗情况:122例患者均顺利完成腹腔镜McKeown三切口食管癌切除术,消化道重建方式采用锥形管状胃联合颈部端端手工分层吻合,无中转开胸或开腹。122例患者手术时间为(229±49)min,颈部吻合时间为(27±1)min,术中出血量为50 mL(40 mL,60 mL)。122例患者清扫6~8组淋巴结,淋巴结清扫数目为19枚(15枚,25枚)。122例患者术后住院时间为10 d(9 d,11 d)。(2)术后并发症情况:122例患者中,31例术后发生并发症。主要术后并发症:3例吻合口瘘,通过保守治疗(胃镜下放置营养管肠内营养、胸腔闭式引流及抗感染)痊愈;6例胸胃扩张患者,及时采取胃肠减压措施后痊愈。22例其他术后并发症患者中,喉返神经损伤导致的声音嘶哑8例,心律失常5例,肺部感染9例,经对症支持治疗后痊愈。122例患者无乳糜胸和围术期死亡发生。(3)随访情况:122例患者均获得随访,随访时间为10~24个月,中位随访时间为19个月。随访期间,7例吻合口狭窄患者(≤2级4例、≥3级3例)通过胃镜下扩张均获得缓解。122例患者中,33例无胃食管反流症状;89例有不同程度的胃食管反流症状,其中1分52例,2分25例,3分12例。122例患者术后1个月消化道钡剂造影检查测量胃食管吻合口宽度为(1.2±0.4)cm。结论 锥形管状胃联合颈部端端分层吻合应用于胸腹腔镜食管癌切除术的消化道重建中,术后吻合口并发症及胸胃扩张发生率低,术中无需常规放置胃管,能很好地保证手术的安全性及普适性。

     

    Abstract: Objective To explore the application value of cone-shaped gastric tube combined with cervical end-to-end anastomosis in thoracoscopic and laparoscopic esophagectomy for esophageal cancer. Methods The retrospective and descriptive study was conducted. The clinical data of 122 patients with esophageal cancer who were admitted to West China Hospital of Sichuan University from December 2016 to December 2017 were collected. There were 89 males and 33 females, aged (61±8)years, with a range from 48 to 81 years. McKeown-type three-incision esophagectomy was performed, and the cone-shaped gastric tube was pulled up to esophagus in left neck for hand-sewn end-to-end anastomosis after the dissection of esophagus and stomach under total thoracoscopy and laparoscopy. Observation indicators: (1) surgical treatment situations; (2) postoperative complications; (3) follow-up. Follow-up using outpatient examination was performed to detect postoperative gastroesophageal reflux, anastomotic stenosis and evaluate anastomotic width at 1, 3, 6 months and one year postoperatively up to December 2018. Measurement data with normal distribution were represented by Mean±SD. Measurement data with skewed distribution were described by M (P25, P75) or M (range). Count data were expressed by absolute number. Results (1) Surgical treatment situations: 122 patients underwent laparocopic McKeown-type three-incision esophagectomy successfully, using cone-shaped gastric tube combined with cervical hand-sewn end-to-end anastomosis as digestive tract reconstruction, with no intraoperative conversion to open surgery. The operation time, cervical anastomosis time, and volume of intraoperative blood loss were (229±49)minutes, (27±1)minutes, and 50 mL (40 mL, 60 mL), respectively. There were 6-8 stations of lymph node dissected, and the number of lymph node dissected were 19 (15, 25). Duration of postoperative hospital stay was 10 days (9 days, 11 days) in the 122 patients. (2) Postoperative complications: 31 of 122 patients had postoperative complications. The primary complications: 3 patients with anastomotic fistula were cured by conservative treatment including enteral nutrition through placement of nutritional tube under gastroscope, closed thoracic drainage and anti-infection; 6 cases with severe thoracic gastric dilation were cured after gastrointestinal decompression. The secondary complications of 22 patients included 8 cases with hoarseness caused by recurrent laryngeal never injury, 5 with arrhythmia, 9 with pulmonary infection. They were cured after symptomatic and supportive treatment. No chylothorax occured, and there was no perioperative death. (3) Follow-up: all the 122 patients were followed up for 10-24 months, with a median time of 19 months. During the follow-up, 7 cases with anastomotic stenosis including 4 scoring less than grade 2 and 3 scoring more than grade 3 were relieved after dilation through gastroscope. There were 33 of 122 patients without any reflux symptoms, and 89 with reflux symptoms, among which 52 were scored 1, 25 were scored 2 and 12 were scored 3. The width of gastroesophageal anastomosis measured by barium radiography at 1 month after operation was (1.2±0.4)cm. Conclusion Cone-shaped gastric tube combined with cervical end-to-end anastomosis in digestive tract reconstruction of thoracoscopic and laparoscopic esophagectomy can reduce the incidence of postoperative anastomotic complications and thoracic gastric dilation, and nasogastric tube placement could be abandoned, which demonstrates good safety and universality.
