    Abstract:
    Objective: To explore the advantages and safety of a modified mattress inversion suturing using double barbed sutures compared with the traditional overlap method in totally laparoscopic esophagojejunostomy overlap anastomosis. Methods: A retrospective cohort study was conducted. The inclusion criteria were as follows: (1) patients were aged 18 - 80 years old; (2) adenocarcinoma was preoperatively confirmed by pathological analysis; (3) patients had undergone a complete laparoscopic radical total gastrectomy; (4) patients had undergone esophagojejunostomy using the overlap method; (5) patients received a grade of I-III on the American Society of Anesthesiologists physical status classification system; (6) patients' complete follow-up data had been collected. Patients with a history of other malignant tumors, multi-origin tumors, emergency surgery, non-R0 radical resection or distant metastasis were excluded. The clinical data of 89 gastric cancer patients who underwent total laparoscopic radical total gastrectomy in the Department of Gastrointestinal Surgery in the Sixth Affiliated Hospital of Sun Yat-sen University from January 2019 to December 2020 were collected. These patients were grouped according to the esophagojejunostomy method used. Of 89 patients, 32 received modified mattress inversion suturing with double barbed sutures to close the common opening of esophagojejunostomy (the modified anastomosis group), while 57 received traditional overlap anastomosis in which the common opening was closed by barbed suture (the traditional anastomosis group). The operation conditions (incision length, conversion to laparotomy, duration of esophagojejunostomy) and postoperative recovery (time to commencement of a liquid diet, duration of postoperative hospital stay, anastomotic leakage, anastomotic stenosis, and anastomotic bleeding) were compared between the two groups. Results: There was no significant difference in the baseline data of the two groups for any parameter (all P>0.05). All patients received complete laparoscopic radical gastrectomy without conversion to laparotomy. There were no significant differences in the length of the median incision, the proportion of food intake on the first day after surgery, or in the incidence of anastomotic complications such as anastomotic leakage, anastomotic stenosis, and anastomotic bleeding between the two groups (P>0.05). Compared with the traditional anastomosis group, patients in the modified anastomosis group had shorter anastomosis time [26 (19-62) minutes vs. 36 (20-50) minutes, Z=-2.546, P=0.011] and postoperative hospital stay [7 (6-12) days vs. 9 (7-42) days, Z=-4.202, P<0.001]. The differences were statistically significant (all P<0.05). In a subgroup analysis of tumor TNM stage III, Siewert type II and neoadjuvant chemotherapy patients, there was no significant difference in the incidence of anastomotic complications between the modified group and the traditional group. However, the postoperative hospital stay duration in the modified anastomosis group was less than in the traditional anastomosis group. The duration of anastomosis in Siewert type II patients was also shorter in the modified anastomosis group than in the traditional anastomosis group [26 (19-62) minutes vs. 38 (21-50) minutes, Z=-2.105, P=0.035], and the difference was statistically significant (all P<0.05). Conclusion: Complete laparoscopic esophagojejunostomy using modified mattress inversion suturing with double barbed sutures is a safe and feasible anastomosis method to close the common opening of esophagojejunostomy, with shorter operation time, faster postoperative recovery and shorter hospital stay than the traditional method. 目的： 探讨双倒刺线改良褥式内翻缝合相比传统Overlap在全腹腔镜食管空肠Overlap吻合中的优势及安全性。 方法： 采用回顾性队列研究方法。病例纳入标准：（1）年龄为18~80岁；（2）术前病理证实为胃腺癌；（3）施行全腹腔镜根治性全胃切除术；（4）采用Overlap法行食管空肠吻合；（5）美国麻醉医师协会分级为Ⅰ~Ⅲ级；（6）随访资料完整。排除同时有其他恶性肿瘤病史或多源性肿瘤者、急症手术者、非R0切除者以及存在远处转移者。收集2019年1月至2020年12月期间，中山大学附属第六医院胃肠外科收治的89例接受全腹腔镜根治性全胃切除术胃癌患者的临床资料。根据食管空肠吻合方式的不同进行分组：32例采用双倒刺线改良褥式内翻缝合关闭食管空肠吻合的共同开口（改良吻合组），57例采用传统Overlap吻合法（共同开口改用倒刺线关闭，传统吻合组）。比较两组手术情况（切口长度、中转开腹情况、食管空肠吻合时间）以及术后恢复情况（术后进食流质时间、术后住院时间以及吻合口漏、吻合口狭窄、吻合口出血等吻合口并发症）。 结果： 两组基线资料的比较，差异均无统计学意义（均P>0.05）。两组患者均顺利完成全腹腔镜胃癌根治性手术，无中转开腹。手术正中切口长度、术后第1天进食比例以及吻合口漏、吻合口狭窄、吻合口出血等吻合口并发症发生率两组比较，差异均无统计学意义（均P>0.05）。与传统吻合组比较，改良吻合组食管空肠吻合时间［26（19~62）min比36（20~50）min，Z=-2.546，P=0.011］和术后住院时间［7（6~12）d比9（7~42）d，Z=-4.202，P<0.001］均较短，差异有统计学意义（均P<0.05）。在肿瘤TNM分期为Ⅲ期和Siewert Ⅱ型及新辅助化疗等亚组分析中，两组的吻合口并发症发生率差异也无统计学意义，但改良吻合组的术后住院时间均少于传统吻合组，其中SiewertⅡ型患者改良吻合组的食管空肠吻合时间也少于传统吻合组［26（19~62）min比38（21~50）min，Z=-2.105，P=0.035］，差异均有统计学意义（均P<0.05）。 结论： 全腹腔镜食管空肠Overlap吻合采用双倒刺线改良褥式内翻缝合关闭食管空肠共同开口安全可行，且具有操作时间更短、术后恢复更快的优势。.
