Digestive tract reconstruction options after laparoscopic gastrectomy for gastric cancer

In addition to the popularity of laparoscopic gastrectomy(LG),many reconstructive procedures after LG have been reported.Surgical resection and lymphatic dissection determine long-term survival;however,the election of a reconstruction procedure determines the postoperative quality of life for patients with gastric cancer(GC).Presently,no consensus exists regarding the optimal reconstructive procedure.In this review,the current state of digestive tract reconstruction after LG is reviewed.According to the determining influence of the tumor site on the procedures of surgical resection and reconstruction,we divide these reconstruction procedures into three categories consistent with the resection procedures.We focus on the technical tips of every reconstruction procedure and examine the surgical outcomes(length of surgery and blood loss)and postoperative complications(anastomotic leakage and stricture)to facilitate gastrointestinal surgeons to understand the merits and demerits of every reconstruction procedure.

Optimal choice of stapler and digestive tract reconstruction method after distal gastrectomy for gastric cancer:A prospective case–control study

BACKGROUND Gastric cancer is the most common cause of cancer-related deaths,and is classified according to its location in the proximal,middle,or distal stomach.Surgical resection is the primary approach for treating gastric cancer.This prospective study aimed to determine the best reconstruction method after distal gastrectomy for gastric cancer.AIM To explore the efficacy of different staplers and digestive tract reconstruction(DTR)methods after radical gastrectomy and their influence on prognosis.METHODS Eighty-seven patients who underwent radical gastrectomy for distal gastric cancer at our institution between April 2017 and April 2020 were included in this study,with a follow-up period of 12-26 mo.The patients were assigned to four groups based on the stapler and DTR plan as follows:BillrothⅠ(B-I)reconstruction+linear stapler group(group A,22 cases),B-I reconstruction+circular stapler group(group B,22 cases),Billroth II(B-II)reconstruction+linear stapler group(group C,22 cases),and B-II reconstruction+circular stapler group(group D,21 cases).The pathological parameters,postoperative gastrointestinal function recovery,postoperative complications,and quality of life(QOL)were compared among the four groups.RESULTS No significant differences in the maximum diameter of the gastric tumors,total number of lymph nodes dissected,drainage tube removal time,QLQ(QOL questionnaire)-C30 and QLQ-STO22 scores at 1 year postoperatively,and incidence of complications were observed among the four groups(P>0.05).However,groups A and C(linear stapler)had significantly lower intraoperative blood loss and significantly shorter anastomosis time,operation time,first fluid diet intake time,first exhaust time,and length of postoperative hospital stay(P<0.05)than groups B and D(circular stapler).CONCLUSION Linear staplers offer several advantages for postoperative recovery.B-I and B-II reconstruction methods had similar effects on QOL.The optimal solution can be selected according to individual conditions and postoperative convenience.

Digestive tract reconstruction pattern as a determining factor in postgastrectomy quality of life

Postgastrectomy quality of life (QoL) is affected by various symptoms, and compared with the preoperative baseline QoL, is typically impaired for the first 6 mo after surgery. Thereafter, improvement to a stable QoL is observed at approximately 12 mo postoperatively. We consider the digestive tract reconstruction pattern to be a determining factor in postgastrectomy QoL among gastric cancer patients, and believe it requires further discussion. Proximal gastrectomy is associated with the worst postoperative QoL among gastrectomy procedures and should be performed cautiously. The trend of better QoL provided by the pouch procedure of total gastrectomy requires further robust support. Whether the use of Billroth-I gastroduodenostomy or Roux-en-Y gastrojejunostomy for distal gastrectomy is optimal remains controversial, but Roux-en-Y gastrojejunostomy is likely to be preferable.

Multifactor analysis of the technique in total laparoscopic gastric cancer

BACKGROUND Esophageal gastric anastomosis is a common surgical technique used to treat patients with gastric cancer who undergo total gastrectomy.However,using simple anastomosis techniques alone may not meet the needs of patients in some cases and can lead to complications such as anastomotic stenosis and ulceration.In order to overcome these issues and improve patient prognosis,muscle flap reconstruction technique has emerged.Muscle flap reconstruction is a method of improving gastric-esophageal anastomosis by transplanting muscle tissue.By covering the anastomotic site with muscle tissue,it not only enhances the stability of the anastomosis site but also increases blood supply,promoting healing and recovery of the anastomosis.Therefore,the use of muscle flap reconstruction technique in esophageal gastric anastomosis during total gastrectomy for gastric cancer is increasingly widely applied.AIM To determine the effectiveness of esophagogastric anastomosis using the muscle flap reconstruction technology in total abdominal gastrectomy for gastric cancer and perform follow-up experiments to understand the factors affecting patients’prognosis.METHODS The study subjects were 60 patients with gastric cancer who were admitted to our hospital between October 2018 and January 2022.All patients underwent esopha-gogastric anastomosis using the double muscle flap reconstruction technology in total abdominal gastrectomy.Perioperative indicators were determined,and INTRODUCTION Gastric cancer is one of the most common tumors of the digestive system worldwide.Although gastric cancer may not have significant manifestations in the early stage,as the disease progresses,systemic symptoms such as emaciation,anemia,and gastric perforation are observed[1].Surgery is the main treatment strategy for gastric cancer.With recent advances in total laparoscopy,total laparoscopic radical resection has gradually become an important treatment strategy for gastric cancer.Conventional laparoscopic surgery may require at least 5-6 incisions,whereas total laparoscopic surgery requires only 3-4 small incisions,decreasing surgical trauma and postoperative pain[2].Furthermore,because total laparoscopic surgery is less invasive than conventional laparoscopic surgery,patients can generally return to normal living and working conditions more quickly[3].Moreover,total laparoscopic surgery does not leave obvious surgical scars;therefore,it is advantageous for patients who pay attention to appearance[4].Esophagogastrostomy is a method used to repair gastrointestinal anastomosis,called the“double muscle valve”.This technique requires folding the fundus of the stomach,followed by sealing it with two layers of tissue,forming a structure similar to a valve.The application of esophagogastrostomy to total laparoscopic radical resection for gastric cancer can effectively decrease the incidence of complications such as anastomotic incontinence and bile reflux and improve the surgical cure rate and postoperative quality of life,which is a recent topic of interest for surgeons.At present,systematic multivariate analyses of the application effects of esophagogastrostomy in total laparoscopic surgery for gastric cancer and their effects on prognosis remain scarce[5].In the present study,we conducted surgery and postoperative follow-up of patients with gastric cancer and collected relevant clinical data for esophagogastric anastomosis during postoperative resection for gastric cancer to ACKNOWLEDGEMENTS I would like to express my sincere thanks to all those who participated in the manuscript.

Novel method for esophagojejunal anastomosis after laparoscopic total gastrectomy:Semi-end-to-end anastomosis

AIM: To test a new safe and simple technique for circular-stapled esophagojejunostomy in laparoscopic total gastrectomy (LATG).

Pouch Roux-en-Yvs No Pouch Roux-en-Y following total gastrectomy:a meta-analysis based on 12 studies

After a total resection of the stomach, the continuity of the gastrointestinal tract can be restored either by Rouxen-Y esophagojejunostomy with or without a pouch. There is still no consensus on the best reconstruction technique. The aim of this report was to derive a more precise estimation of Roux-en-Y esophagojejunostomy with a pouch compared with Roux-en-Y esophagojejunostomy without a pouch. Studies were identified by PubMed and Embase searches, and the inclusion criteria were randomized controlled trials （RCTs） comparing reconstruction techniques between Roux-en-Y with and without a pouch. A total of 12 studies including 1,018 patients were included. The meta-analysis shows that pouch Roux-en-Y does not significantly increase total postoperative complications, anastomotic leakage or mortality, hnportantly, there is no significant difference in S-year survival rates between the two groups. Patients with Roux-en-Y esophagojejunostomy complained significantly less of reflux symptoms and dumping syndrome, and had significantly less severe reflux esophagitis. Quality of life was significantly improved in patients with Roux-en-Y esophagojejunostomy with a pouch compared with patients who received Roux-en-Y reconstruction without a pouch. The results indicate the need for Roux-en-Y esophagojeju- nostomy with a pouch is a gastric substitute after total gastrectomy by comparison with Roux-en-Y esophagojejunostomy without a pouch.

Clinical efficacy and safety of double-channel anastomosis and tubular gastroesophageal anastomosis in gastrectomy

BACKGROUND With the continuous progress of surgical technology and improvements in medical standards,the treatment of gastric cancer surgery is also evolving.Proximal gastrectomy is a common treatment,but double-channel anastomosis and tubular gastroesophageal anastomosis have attracted much attention in terms of surgical options.Each of these two surgical methods has advantages and disadvantages,so it is particularly important to compare and analyze their clinical efficacy and safety.AIM To compare the surgical safety,clinical efficacy,and safety of double-channel anastomosis and tubular gastroesophageal anastomosis in proximal gastrectomy.METHODS The clinical and follow-up data of 99 patients with proximal gastric cancer who underwent proximal gastrectomy and were admitted to our hospital between January 2018 and September 2023 were included in this retrospective cohort study.According to the different anastomosis methods used,the patients were divided into a double-channel anastomosis group(50 patients)and a tubular gastroesophageal anastomosis group(49 patients).In the double-channel anastomosis,Roux-en-Y anastomosis of the esophagus and jejunum was performed after proximal gastric dissection,and then side-to-side anastomosis was performed between the residual stomach and jejunum to establish an antireflux barrier and reduce postoperative gastroesophageal reflux.In the tubular gastroesophageal anastomosis group,after the proximal end of the stomach was cut,tubular gastroplasty was performed on the distal stump of the stomach and a linear stapler was used to anastomose the posterior wall of the esophagus and the anterior wall of the stomach tube.The main outcome measure was quality of life 1 year after surgery in both groups,and the evaluation criteria were based on the postgastrectomy syndrome assessment scale.The greater the changes in body mass,food intake per meal,meal quality subscale score,and total measures of physical and mental health score,the better the condition;the greater the other indicators,the worse the condition.The secondary outcome measures were intraoperative and postoperative conditions,the incidence of postoperative long-term complications,and changes in nutritional status at 1,3,6,and 12 months after surgery.RESULTS In the double-channel anastomosis cohort,there were 35 males(70%)and 15 females(30%),33(66.0%)were under 65 years of age,and 37(74.0%)had a body mass index ranging from 18 to 25 kg/m2.In the group undergoing tubular gastroesophageal anastomosis,there were eight females(16.3%),21(42.9%)individuals were under the age of 65 years,and 34(69.4%)had a body mass index ranging from 18 to 25 kg/m2.The baseline data did not significantly differ between the two groups(P>0.05 for all),with the exception of age(P=0.021).The duration of hospitalization,number of lymph nodes dissected,intraoperative blood loss,and perioperative complication rate did not differ significantly between the two groups(P>0.05 for all).Patients in the dual-channel anastomosis group scored better on quality of life measures than did those in the tubular gastroesophageal anastomosis group.Specifically,they had lower scores for esophageal reflux[2.8(2.3,4.0)vs 4.8(3.8,5.0),Z=3.489,P<0.001],eating discomfort[2.7(1.7,3.0)vs 3.3(2.7,4.0),Z=3.393,P=0.001],total symptoms[2.3(1.7,2.7)vs 2.5(2.2,2.9),Z=2.243,P=0.025],and other aspects of quality of life.The postoperative symptoms[2.0(1.0,3.0)vs 2.0(2.0,3.0),Z=2.127,P=0.033],meals[2.0(1.0,2.0)vs 2.0(2.0,3.0),Z=3.976,P<0.001],work[1.0(1.0,2.0)vs 2.0(1.0,2.0),Z=2.279,P=0.023],and daily life[1.7(1.3,2.0)vs 2.0(2.0,2.3),Z=3.950,P<0.001]were all better than those of the tubular gastroesophageal anastomosis group.The group that underwent tubular gastroesophageal anastomosis had a superior anal exhaust score[3.0(2.0,4.0)vs 3.5(2.0,5.0),Z=2.345,P=0.019]compared to the dual-channel anastomosis group.Hemoglobin,serum albumin,total serum protein,and the rate at which body mass decreased one year following surgery did not differ significantly between the two groups(P>0.05 for all).CONCLUSION The safety of double-channel anastomosis in proximal gastric cancer surgery is equivalent to that of tubular gastric surgery.Compared with tubular gastric surgery,double-channel anastomosis is a preferred surgical technique for proximal gastric cancer.It offers advantages such as less esophageal reflux and improved quality of life.

Comparison of long-term quality of life between Billroth-I and Roux-en-Y anastomosis after distal gastrectomy for gastric cancer: a randomized controlled trial

Background:The results of studies comparing Billroth-I(B-I)with Roux-en-Y(R-Y)reconstruction on the quality of life(QoL)are still inconsistent.The aim of this trial was to compare the long-term QoL of B-I with R-Y anastomosis after curative distal gastrectomy for gastric cancer.Methods:A total of 140 patients undergoing curative distal gastrectomy with D2 lymphadenectomy in West China Hospital,Sichuan University from May 2011 to May 2014 were randomly assigned to the B-I group(N=70)and R-Y group(N=70).The follow-up time points were 1,3,6,9,12,24,36,48,and 60 months after the operation.The final follow-up time was May 2019.The clinicopathological features,operative safety,postoperative recovery,long-term survival as well as QoL were compared,among which QoL score was the primary outcome.An intention-to-treat analysis was applied.Results:The baseline characteristics were comparable between the two groups.There were no statistically significant differences in terms of postoperative morbidity and mortality rates,and postoperative recovery between the two groups.Less estimated blood loss and shorter surgical duration were found in the B-I group.There were no statistically significant differences in 5-year overall survival(79%[55/70]of the B-I group vs.80%[56/70]of the R-Y group,P=0.966)and recurrence-free survival rates(79%[55/70]of the B-I group vs.78%[55/70]of the R-Y group,P=0.979)between the two groups.The scores of the global health status of the R-Y group were higher than those of the B-I group with statistically significant differences(postoperative 1 year:85.4±13.1 vs.88.8±16.1,P=0.033;postoperative 3 year:87.3±15.2 vs.92.8±11.3,P=0.028;postoperative 5 year:90.9±13.7 vs.96.4±5.6,P=0.010),and the reflux(postoperative 3 year:8.8±12.9 vs.2.8±5.3,P=0.001;postoperative 5 year:5.1±9.8 vs.1.8±4.7,P=0.033)and epigastric pain(postoperative 1 year:11.8±12.7 vs.6.1±8.8,P=0.008;postoperative 3 year:9.4±10.6 vs.4.6±7.9,P=0.006;postoperative 5 year:6.0±8.9 vs.2.7±4.6,P=0.022)were milder in the R-Y group than those of the B-I group at the postoperative 1,3,and 5-year time points.Conclusions:Compared with B-I group,R-Y reconstruction was associated with better long-term QoL by reducing reflux and epigastric pain,without changing survival outcomes.Trial Registration:ChiCTR.org.cn,ChiCTR-TRC-10001434.

目的:比较毕Ⅰ式吻合术与ROUX-en-Y吻合术在全腹腔镜远端胃癌根治术消化道重建中的应用效果。方法:选取2022年1月—2023年12月于甘肃省武威肿瘤医院行全腹腔镜远端胃癌根治术的胃癌患者120例作为研究对象,随机分为对照组和研究组,各60例。对照组采用毕Ⅰ式吻合术进行消化道重建,研究组采用ROUX-en-Y吻合术进行消化道重建。比较两组围术期指标、并发症发生情况、术后疼痛情况及炎性因子水平。结果:研究组术中出血量少于对照组,首次排气时间早于对照组,住院时间短于对照组,差异有统计学意义(P<0.05);两组手术时间比较,差异无统计学意义(P>0.05);研究组并发症总发生率低于对照组,差异有统计学意义(P=0.030);术后12h、24h、48h,研究组视觉模拟评分法评分低于对照组,差异有统计学意义(P<0.001);术后,两组白细胞介素-6、C反应蛋白水平升高,研究组低于对照组,差异有统计学意义(P<0.05)。结论:全腹腔镜远端胃癌根治术消化道重建中采用ROUX-en-Y吻合术较毕Ⅰ式吻合术效果更佳,能降低术中出血量,缩短术后恢复时间,降低并发症发生率,减轻疼痛,缓解炎性反应。

残胃癌外科手术治疗经验及消化道重建新方法

１９７２年１月～１９９６年１２月，收治残胃癌３９例，其发病率为１．８５％（３９／２１１０）。本文对其发生病因、发病率、外科处理及防治措施进行探讨。强调外科治疗要早诊早治。残胃癌要残胃全切除合并邻近脏器联合切除及Ｄ＋２、Ｄ３淋巴结廓清术。消化道重建方式推荐空肠原位间置代胃术、空肠Ｒｏｕｘ－Ｙ重建消化道新方法。才能取得满意疗效。

三角吻合术对胃癌伴T2DM患者全腹腔镜远端胃切除术后糖代谢的影响

目的探讨全腹腔镜远端胃切除术(total laparoscopic distal gastrectomy,TLDG)后行三角吻合消化道重建对胃癌合并2型糖尿病(T2DM)患者糖代谢的影响。方法将90例行TLDG的胃癌伴T2DM患者分为观察组(n=36)与对照组(n=54),观察组行三角吻合术,对照组行Billroth-Ⅰ式吻合。比较两组围手术期情况,术前及术后1、3、6个月测定体质量指数(BMI)、胰岛素用量、空腹血糖(FPG)、餐后2 h血糖(2hPG)、糖化血红蛋白(HbAlc)、血清肿瘤坏死因子α(TNF-α)、白介素-6(IL-6)、网模素-1(omentin-1)、脂联素(adiponectin)、抑胃肽(gastric inhibitory peptide,GIP)、胰高血糖素样肽-1(glucagon-like peptide-1, GLP-1)及GIP/GLP-1。结果观察组的切口长度、手术时间、术中出血量、术后排气时间及住院时间均显著低于对照组(P<0.05)。术后1、3、6个月,观察组的BMI、FPG、2hPG、HbAlc和血清TNF-α、IL-6、GIP、GIP/GLP-1水平均显著低于对照组(P<0.05),而网模素-1、脂联素水平显著高于对照组(P<0.05)。结论胃癌伴T2DM患者行TLDG联合三角吻合消化道重建安全可行,较经典Billroth-Ⅰ式吻合更有利于改善术后糖代谢状态。

早期近端胃癌行腹腔镜辅助下近端胃切除双通路吻合术的短期手术疗效观察

目的为评估早期近端胃癌保功能手术的可行性与益处,比较早期胃癌患者行腹腔镜辅助近端胃切除双通道吻合术与腹腔镜辅助全胃切除Roux-en-Y消化道重建术的短期手术效果。方法选取2016年5月-2018年5月29例早期近端胃癌患者接受近端胃切除双通道吻合术;同时选取该院2015年6月以来行全胃切除Roux-en-Y消化道重建术的早期近端胃癌患者,做人口统计学信息、合并症、肿瘤特征和TNM分期配对,对两组患者的围术期和短期手术结果进行比较。结果两组患者的术后病理学特征相近,两组患者均无中转开腹及均未出现术中并发症,两组患者手术时间、术中出血量、术后肛门首次排气时间、首次进食时间及术后住院时间比较,差异均无统计学意义,双通道组淋巴结清扫量(16.73±5.68)枚明显少于全胃切除组(21.43±4.09)枚,两组比较,差异有统计学意义(P=0.023)。每组患者均无吻合口瘘、吻合口出血、反流性食管炎、切口感染及淋巴瘘的记录,两组患者并发症发生率和围术期炎症反应比较,差异无统计学意义。术后随访3个月发现,较之全胃切除Roux-en-Y消化道重建术患者,近端胃切除双通道吻合术患者生活满意度高,两组患者术后体重均较术前下降,其中全胃切除组患者术后体重下降较双通道组比例更高,两组比较,差异有统计学意义(P<0.05);两组患者术前和术后1个月血红蛋白比较,差异无统计学意义,术后2和3个月随访结果显示,双通道组血红蛋白量较全胃切除组高,两组比较,差异有统计学意义(P<0.05);在术前、术后1及2个月,两组患者的血清白蛋白量比较,差异无统计学意义,术后3个月时,双通道组患者血清白蛋白量(41.45±3.68)g/L明显高于全胃切除组(38.45±4.96)g/L,差异有统计学意义(P=0.035)。结论早期近端胃癌行腹腔镜辅助下近端胃切除双通道吻合术有较好的可行性和安全性,近期疗效满意,与全胃切除组比较,双通路术式不增加围术期并发症的发生率,而患者术后营养状况更好,术后体重下降率更低。
