目的

探讨全腹腔镜λ型非离断间置空肠吻合术在近端胃切除术后消化道重建的应用及效果,为近端胃切除术后消化道重建提供一种新的选择。

方法

回顾性分析2023年10月至2024年4月行全腹腔镜下的近端胃切除并采用λ型非离断间置空肠吻合术重建消化道的11例患者的临床资料。分析其临床特征、围手术期指标、术后及随访结果。采用胃镜、上消化道造影及营养评分联合评估患者术后反流性食管炎及营养状况。

结果

11例患者均成功实施了目标术式吻合重建消化道。平均手术时间(192.9±36.2)min、术中出血(104.5±47.2)ml、术后恢复排气(3.5±0.5)d、首次进食时间(4.5±0.5)d、住院时间(15.3±1.7)d、淋巴结清扫数目44枚。平均营养指数(PNI):术前为(54.7±6.1)、术后1个月为(45.2±6.3)、术后6个月为(49.7±3.5)、术后12个月为(52.8±4.2)。11例患者无早期并发症发生。晚期并发症总发生率为27.2%(3/11),食管吻合口狭窄1例,经内镜下扩张治疗后好转;反流性食管炎(LA-B)1例和胃食管反流症状1例,经饮食宣教和药物治疗后缓解。

结论

对于胃上三分之一的早期腺癌及肿瘤直径≤4cm食管胃结合部的SiewertⅡ/Ⅲ腺癌,行全腹腔镜下近端胃切除并采用λ型非离断间置空肠吻合术重建消化道在技术上是可行且安全的,患者术后短期疗效较好。该手术方式有望为近端胃切除术消化道重建提供一种新的选择。

Objective

To explore the application and efficacy of total laparoscopic λ-shaped uncut jejunojejunostomy in digestive tract reconstruction after proximal gastrectomy, and to provide a new option for digestive tract reconstruction following proximal gastrectomy.

Methods

A retrospective analysis was conducted on the clinical data of 11 patients who underwent total laparoscopic proximal gastrectomy with digestive tract reconstruction via λ-shaped uncut jejunojejunostomy from October 2023 to April 2024. Their clinical characteristics, perioperative indicators, postoperative outcomes, and follow-up results were analyzed. Gastroscopy, upper gastrointestinal radiography, and nutritional scoring were combined to evaluate postoperative reflux esophagitis and nutritional status of the patients.

Results

All 11 patients successfully underwent the target surgical anastomosis for digestive tract reconstruction. The perioperative indicators were as follows: mean operation time (192.9±36.2) minutes, intraoperative blood loss (104.5±47.2) ml, time to first postoperative flatus (3.5±0.5) days, time to first oral intake (4.5±0.5) days, length of hospital stay (15.3±1.7) days, and the number of lymph nodes dissected was 44. The mean prognostic nutritional index (PNI) was (54.7±6.1) preoperatively, (45.2±6.3) at 1 month postoperatively, (49.7±3.5) at 6 months postoperatively, and (52.8±4.2) at 12 months postoperatively. No early complications occurred in the 11 patients. The total incidence of late complications was 27.2% (3/11): 1 case of esophageal anastomotic stricture, which improved after endoscopic dilation therapy; 1 case of reflux esophagitis (LA-B grade) and 1 case of gastroesophageal reflux symptoms, both of which were relieved after dietary education and drug treatment.

Conclusions

For early adenocarcinoma of the upper one-third of the stomach and Siewert type Ⅱ/Ⅲ adenocarcinoma of the esophagogastric junction with a tumor diameter ≤ 4cm, total laparoscopic proximal gastrectomy combined with digestive tract reconstruction via λ-shaped uncut jejunojejunostomy is technically feasible and safe, with favorable short-term postoperative efficacy. This surgical approach is expected to provide a new option for digestive tract reconstruction after proximal gastrectomy.
