BACKGROUND The development of laparoscopic technology has provided a new choice for surgery of gastric cancer(GC),but the advantages and disadvantages of laparoscopic total gastrectomy(LTG)and laparoscopic-assisted total gastrectomy(LATG)in treatment effect and safety are still controversial.The purpose of this study is to compare the efficacy and safety of the two methods in the treatment of GC,and to provide a basis for clinical decision-making.AIM To compare the efficacy of totally LTG(TLTG)and LATG in the context of radical gastrectomy for GC.Additionally,we investigated the safety and feasibility of the total laparoscopic esophagojejunostomy technique.METHODS Literature on comparative studies of the above two surgical methods for GC(TLTG group and LATG group)published before September 2022 were searched in the PubMed,Web of Science,Wanfang Database,CNKI,and other Chinese and English databases.In addition,the following search keywords were used:Gastric cancer,total gastrectomy,total laparoscopy,laparoscopy-assisted,esophagojejunal anastomosis,gastric/stomach cancer,total gastrectomy,totally/completely laparoscopic,laparoscopic assisted/laparoscopy assisted/laparoscopically assisted,and esophagojejunostomy/esophagojejunal anastomosis.Review Manager 5.3 software was used for the meta-analysis after two researchers independently screened the literature,extracted the data,and evaluated the risk of bias in the included studies.RESULTS After layer-by-layer screening,258 pieces of literature were recovered,and 11 of those pieces were eventually included.This resulted in a sample size of 2421 instances,with 1115 cases falling into the TLTG group and 1306 cases into the LATG group.Age or sex differences between the two groups were not statistically significant,according to the meta-analysis,however the average body mass index of the TLTG group was considerably higher than that of the LATG group(P=0.01).Compared with those in the LATG group,the incision length in the TLTG group was significantly shorter(P<0.001),the amount of intraoperative blood loss was significantly lower(P=0.003),the number of lymph nodes removed was significantly greater(P=0.04),and the time of first postoperative feeding and postoperative hospitalization were also significantly shorter(P=0.03 and 0.02,respectively).There were no significant differences in tumor size,length of proximal incisal margin,total operation time,anastomotic time,postoperative pain score,postoperative anal exhaust time,postoperative anastomosis-related complications(including anastomotic fistula,anastomotic stenosis,and anastomotic hemorrhage),or overall postoperative complication rate(P>0.05).CONCLUSION TLTG and esophagojejunostomy are safe and feasible.Compared with LATG,TLTG has the advantages of less trauma,less bleeding,easier access to lymph nodes,and faster postoperative recovery,and TLTG is also suitable for obese patients. 展开更多

BACKGROUND Laparoscopic radical gastrectomy is widely used,and perioperative complications have become a highly concerned issue.AIM To develop a predictive model for complications in laparoscopic radical gastrectomy for gastric cancer to better predict the likelihood of complications in gastric cancer patients within 30 days after surgery,guide perioperative treatment strategies for gastric cancer patients,and prevent serious complications.METHODS In total,998 patients who underwent laparoscopic radical gastrectomy for gastric cancer at 16 Chinese medical centers were included in the training group for the complication model,and 398 patients were included in the validation group.The clinicopathological data and 30-d postoperative complications of gastric cancer patients were collected.Three machine learning methods,lasso regression,random forest,and artificial neural networks,were used to construct postoperative complication prediction models for laparoscopic distal gastrectomy and laparoscopic total gastrectomy,and their prediction efficacy and accuracy were evaluated.RESULTS The constructed complication model,particularly the random forest model,could better predict serious complications in gastric cancer patients undergoing laparoscopic radical gastrectomy.It exhibited stable performance in external validation and is worthy of further promotion in more centers.CONCLUSION Using the risk factors identified in multicenter datasets,highly sensitive risk prediction models for complications following laparoscopic radical gastrectomy were established.We hope to facilitate the diagnosis and treatment of preoperative and postoperative decision-making by using these models. 展开更多

BACKGROUND Previously,some studies have proposed that total laparoscopic gastrectomy(TLG)is superior to laparoscopic-assisted gastrectomy(LAG)in terms of safety and feasibility based on the related intraoperative operative parameters and incidence of postoperative complications.However,there are still few studies on the changes in postoperative liver function in patients undergoing LG.The present study compared the postoperative liver function of patients with TLG and LAG,aiming to explore whether there is a difference in the influence of TLG and LAG on the liver function of patients.AIM To investigate whether there is a difference in the influence of TLG and LAG on the liver function of patients.METHODS The present study collected 80 patients who underwent LG from 2020 to 2021 at the Digestive Center(including the Department of Gastrointestinal Surgery and the Department of General Surgery)of Zhongshan Hospital affiliated with Xiamen University,including 40 patients who underwent TLG and 40 patients who underwent LAG.Alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP),γ-glutamyltransferase(GGLT),total bilirubin(TBIL),direct bilirubin(DBIL)and indirect bilirubin(IBIL),and other liver function-related test indices were compared between the 2 groups before surgery and on the 1^(st),3^(rd),and 5^(th) d after surgery.RESULTS The levels of ALT and AST in the 2 groups were significantly increased on the 1st to 2nd postoperative days compared with those before the operation.The levels of ALT and AST in the TLG group were within the normal range,while the levels of ALT and AST in the LAG group were twice as high as those in the TLG group(P<0.05).The levels of ALT and AST in the 2 groups showed a downward trend at 3-4 d and 5-7 d after the operation and gradually decreased to the normal range(P<0.05).The GGLT level in the LAG group was higher than that in the TLG group on postoperative days 1-2,the ALP level in the TLG group was higher than that in the LAG group on postoperative days 3-4,and the TBIL,DBIL and IBIL levels in the TLG group were higher than those in the LAG group on postoperative days 5-7(P<0.05).No significant difference was observed at other time points(P>0.05).CONCLUSION Both TLG and LAG can affect liver function,but the effect of LAG is more serious.The influence of both surgical approaches on liver function is transient and reversible.Although TLG is more difficult to perform,it may be a better choice for patients with gastric cancer combined with liver insufficiency. 展开更多

AIM To evaluate the short-term outcomes and quality of life(Qo L) in gastric cancer patients undergoing digestive tract construction using the isoperistaltic jejunum-latercut overlap method(IJOM) after totally laparoscopic total gastrectomy(TLTG).METHODS A total of 507 patients who underwent laparoscopic gastrectomy(D2) from January 2014 to March 2016 were originally included in the study. The patients were divided into two groups to undergo digestive tract construction using either IJOM after TLTG(group T, n = 51) or Roux-en-Y anastomosis after laparoscopic-assisted total gastrectomy(LATG)(group A, n = 456). The short-term outcomes and Qo L were compared between the two groups after 1:2 propensity-score matching(PSM). We used a questionnaire to assess Qo L.RESULTS Before matching, age, sex, tumor size, tumor location, preoperative albumin and blood loss were significantly different between the two groups(P < 0.05). After PSM, the patients were well balanced in terms of their clinicopathological characteristics, although both blood loss and in-hospital postoperative days in group T were significantly lower than those in group A(P < 0.05). After matching, group T reported better Qo L in the domains of pain and dysphagia. Among the items evaluating pain and dysphagia, group T tended to report better Qo L("Have you felt pain" and "Have you had difficulty eating solid food")(P < 0.05).CONCLUSION The IJOM for digestive tract reconstruction after TLTG is associated with reduced blood loss and less pain and dysphagia, thus improving Qo L after laparoscopic gastrectomy. 展开更多

BACKGROUND Although several methods of totally laparoscopic total gastrectomy(TLTG)have been reported.The best anastomosis technique for LTG has not been established.AIM To investigate the effectiveness and surgical outcomes of TLTG using the modified overlap method compared with open total gastrectomy(OTG)using the circular stapled method.METHODS We performed 151 and 131 surgeries using TLTG with the modified overlap method and OTG for gastric cancer between March 2012 and December 2018.Surgical and oncological outcomes were compared between groups using propensity score matching.In addition,we analyzed the risk factors associated with postoperative complications.RESULTS Patients who underwent TLTG were discharged earlier than those who underwent OTG[TLTG(9.62±5.32)vs OTG(13.51±10.67),P<0.05].Time to first flatus and soft diet were significantly shorter in TLTG group.The pain scores at all postoperative periods and administration of opioids were significantly lower in the TLTG group than in the OTG group.No significant difference in early,late and esophagojejunostomy(EJ)-related complications or 5-year recurrence free and overall survival between groups.Multivariate analysis demonstrated that body mass index[odds ratio(OR),1.824;95%confidence interval(CI):1.029-3.234,P=0.040]and American Society of Anaesthesiologists(ASA)score(OR,3.154;95%CI:1.084-9.174,P=0.035)were independent risk factors of early complications.Additionally,age was associated with≥3 Clavien-Dindo classification and EJrelated complications.CONCLUSION Although TLTG with the modified overlap method showed similar complication rate and oncological outcome with OTG,it yields lower pain score,earlier bowel recovery,and discharge.Surgeons should perform total gastrectomy cautiously and delicately in patients with obesity,high ASA scores,and older ages. 展开更多

BACKGROUND Prophylactic drains have been used to remove intraperitoneal collections and detect complications early in open surgery.In the last decades,minimally invasive gastric cancer surgery has been performed worldwide.However,reports on routine prophylactic abdominal drainage after totally laparoscopic distal gastrectomy are few.AIM To evaluate the feasibility performing totally laparoscopic distal gastrectomy without prophylactic drains in selected patients.METHODS Data of patients with distal gastric cancer who underwent totally laparoscopic distal gastrectomy with and without prophylactic drainage at China National Cancer Center/Cancer Hospital from February 2018 to August 2019 were reviewed.The outcomes between patients with and without prophylactic drainage were compared.RESULTS A total of 457 patients who underwent surgery for gastric cancer were identified.Of these,125 patients who underwent totally laparoscopic distal gastrectomy were included.After propensity score matching,data of 42 pairs were extracted.The incidence of concurrent illness was higher in the drain group(42.9%vs 31.0%,P=0.258).The overall postoperative complication rates were 19.5%and 10.6%in the drain(n=76)and no-drain groups(n=49),respectively;there were no significant differences between the two groups(P>0.05).The difference between the two groups based on the need for percutaneous catheter drainage was also not significant(9.8%vs 6.4%,P=0.700).However,patients with a larger body mass index(≥29 kg/m2)were prone to postoperative complications(P=0.042).In addition,the number of days from surgery until the first flatus(4.33±1.24 d vs 3.57±1.85 d,P=0.029)was greater in the drain group.CONCLUSION Omitting prophylactic drainage may reduce surgery time and result in faster recovery.Routine prophylactic drains are not necessary in selected patients.A prophylactic drain may be useful in high-risk patients. 展开更多

BACKGROUND Totally laparoscopic gastrectomy(TLG)entails both gastrectomy and gastrointestinal reconstruction under laparoscopy.Compared with laparoscopic assisted gastrectomy(LAG),TLG has been demonstrated in many studies to require a smaller surgical incision,result in a faster postoperative recovery and less pain and have comparable long-term efficacy,which has been a research hotspot in recent years.Whether TLG is equally safe and feasible for elderly patients remains unclear.AIM To compare the short-term efficacy of and quality of life(QOL)associated with TLG and LAG in elderly gastric cancer(GC)patients.METHODS The clinicopathological data of 462 elderly patients aged≥70 years who underwent LAG or TLG(including distal gastrectomy and total gastrectomy)between January 2017 and January 2022 at the Department of General Surgery,First Medical Center,Chinese PLA General Hospital were retrospectively collected.A total of 232 patients were in the LAG group,and 230 patients were in the TLG group.Basic patient information,clinicopathological characteristics,operation information and QOL data were collected to compare efficacy.Compared with those in the LAG group,intraoperative blood loss in the TLG group was significantly lower(P<0.001),and the time to first flatus and postoperative hospitalization time were significantly shorter(both P<0.001).The overall incidence of postoperative complications in the TLG group was significantly lower than that in the LAG group(P=0.01).Binary logistic regression results indicated that LAG and an operation time>220 min were independent risk factors for postoperative complications in elderly patients with GC(P<0.05).In terms of QOL,no statistically significant differences in various preoperative indicators were found between the LAG group and the LTG group(P>0.05).Compared with the laparoscopic-assisted total gastrectomy group,patients who received totally laparoscopic total gastrectomy had lower nausea and vomiting scores and higher satisfaction with their body image(P<0.05).Patients who underwent laparoscopic-assisted distal gastrectomy were more satisfied with their body image than patients in the totally laparoscopic distal gastrectomy group(P<0.05).CONCLUSION TLG is safe and feasible for elderly patients with GC and has outstanding advantages such as reducing intracorporeal blood loss,promoting postoperative recovery and improving QOL. 展开更多

BACKGROUND Laparoscopic total gastrectomy(LTG)has drawn increasing attention over the years.Although LTG has shown surgical benefits compared to open TG(OTG)in early stage gastric cancer(GC),little is known about the surgical and oncological outcomes of LTG for advanced GC following neoadjuvant therapy(NAT).AIM To compare the long-and short-term outcomes of advanced GC patients who underwent LTG vs OTG following NAT.METHODS Advanced GC patients who underwent TG following NAT between April 2011 and May 2018 at the Cancer Hospital of the Chinese Academy of Medical Sciences were enrolled and stratified into two groups:LTG and OTG.Propensity score matching analysis was performed at a 1:1 ratio to overcome possible bias.RESULTS In total,185 patients were enrolled(LTG:78;OTG:109).Of these,138 were paired after propensity score matching.After adjustment for propensity score matching,baseline parameters were similar between the two groups.Compared to OTG,LTG was associated with a significantly shorter length of hospital stay(P=0.012).The rates of R0 resection,lymph node harvest,and postoperative morbidity did not significantly differ between the two groups.Overall survival(OS)outcomes were comparable between the two groups.Pathological T and N stages were found to be independent risk factors for OS.CONCLUSION LTG can be a feasible method for advanced GC patients following NAT,as it appears to be associated with better short-and comparable long-term outcomes compared to OTG. 展开更多

BACKGROUND Intraoperative methylene blue testing(IMBT),air leak testing,or endoscopy is used to assess the anastomotic integrity of esophagojejunostomy during open total gastrectomy for gastric cancer.Totally laparoscopic radical gastrectomy has been widely used to treat gastric cancer in the last few decades.However,reports on testing anastomotic integrity in totally laparoscopic radical gastrectomy are limited.AIM To explore the effects of IMBT on the incidence of postoperative anastomotic leaks(PALs)and identify the risk factors for PALs in totally laparoscopic radical gastrectomy.METHODS From January 2017 to December 2019,patients who underwent totally laparoscopic radical gastrectomy at the Shaanxi Provincial People's Hospital were retrospectively analyzed.According to whether or not they experienced an IMBT,the patients were divided into an IMBT group and a control group.If the IMBT was positive,an intraoperative suture was required to reinforce the anastomosis.The difference in the incidence of PALs was compared,and the risk factors were investigated.RESULTS This study consisted of 513 patients,211 in the IMBT group and 302 in the control group.Positive IMBT was shown in seven patients(3.3%)in the IMBT group,and no PAL occurred in these patients after suture reinforcement.Multivariate analysis showed that risk factors for predicting positive IMBT were body mass index(BMI)>25 kg/m2(hazard ratio[HR]=8.357,P=0.009),operation time>4 h(HR=55.881,P=0.002),and insufficient surgical experience(HR=15.286,P=0.010).Moreover,15 patients(2.9%)developed PALs in 513 patients,and the rates of PALs were significantly lower in the IMBT group than in the control group[2 of 211 patients(0.9%)vs 13 of 302 patients(4.3%),P=0.0026].Further analysis demonstrated that preoperative complications(HR=13.128,P=0.017),totally laparoscopic total gastrectomy(HR=9.075,P=0.043),and neoadjuvant chemotherapy(HR=7.150,P=0.008)were independent risk factors for PALs.CONCLUSION IMBT is an effective method to evaluate the integrity of anastomosis during totally laparoscopic radical gastrectomy,thus preventing technical defect-related anastomotic leaks.Preoperative complications,totally laparoscopic total gastrectomy,and neoadjuvant chemotherapy are independent risk factors for PALs. 展开更多

BACKGROUND Overlapped esophagojejunostomy(OEJ) is a secure purely laparoscopic reconstruction after laparoscopic total gastrectomy(LTG). However, long-term surgical results have not been documented well.AIM In this paper, we report unusual patients who manifested jejunal limb stricture near the esophageal hiatus without anastomotic stenosis during long-term observation after surgery.METHODS From April 2009 until May 2020, we retrospectively reviewed 211 patients underwent LTG following by OEJ for gastric carcinoma and took a standard surveillance program. We aimed to characterize a novel complicated disorder observed in these patients to assist treatment and prevention.RESULTS Five patients(2.4%) had unusual jejunal limb stricture after LTG and OEJ,occurring at a mean of 10 mo after initial radical LTG. All five patients had disturbed oral intake and marked weight loss, and two had aspiration pneumonia.Various diagnostic modalities and intraoperative findings in each patient revealed an intact anastomosis, bent or tortuous jejunal limb resulting from loose fibrous adhesions on the left crus at the esophageal hiatus and no cancer recurrence. All five patients were successfully treated by reoperation for adhesiolysis, division of the left crus and rearrangement of the jejunal limb.CONCLUSION Disturbed passage through the jejunal limb near the hiatus can occur after some types of OEJ following LTG. We speculate that it may result from a short remnant esophagus, excessive mobilization of the jejunal limb that permits bending or tortuosity and adhesions on the left crus at the hiatus. Prevention for this complication is possible during the original LTG procedure. 展开更多

Gastric cancer poses a significant public health problem, especially in the Far East, due to its high incidence in these areas. Surgical treatment and guidelines have been markedly different in the West, but nowadays this debate is apparently coming to an end. Laparoscopic surgery has been employed in the surgical treatment of gastric cancer for two decades now, but with controversies about the extent of resection and lymphadenectomy. Despite these difficulties, the apparent advantages of the laparoscopic approach helped its implementation in early stage and distal gastric cancer, with an increase on the uptake for distal gastrectomy for more advanced disease and total gastrectomy. Nevertheless, there is no conclusive evidence about the laparoscopic approach yet. In this review article we present and analyse the current status of laparoscopic surgery in the treatment of gastric cancer. 展开更多

Objective:To analyze the basis and medication rules of Chinese herbs in the regulation of necroptosis.Methods:With the help of GeneCards,DrugBank,TTD,DisGeNET,OMIM database to collect the action targets of necroptosis,the TCMSP database to obtain the target‑related compounds and Chinese herbs,and the ADME criteria and Lipinski rule as the conditions for screening,to build the target‑compound,target‑compound‑Chinese herbs network.The information of Chinese herbal medicine's sexual taste and meridian was collected,and the drug use pattern was analyzed.The information on the property,flavor and channel tropism of Chinese herbs was collected to analyze the medication laws.Molecular docking of core targets and compounds in the network with AutoDockTools software,and PyMOL software was used to display the combinations with good docking results.Results:A total of 12 potential targets acting on necroptosis were obtained,matching to 191 candidate compounds and 366 herbal medicines.Quercetin,wogonin,triptolide,licochalcone a,ellipticine are more important and may be the main small molecule substances underlying the regulation of necroptosis.The more important Chinese herbs are Licorice,Forsythia,Salivae Miltiorrhizae,Ginkgo Leaf,Eucommia ulmoides Oliv,etc.The herbal medicines are mainly bitter and pungent,with cold and warm taste,which were attributed to the liver and lung meridians.BCL2‑beta‑sitosterol、MAPK14‑luteolin、MAPK14‑formononetin、TP53‑formononetin are better molecular docking results,which have strong docking activity.Conclusion:The study systematically analyzes the material basis of regulating necroptosis and summarizes the general rule of regulating necroptosis in Chinese medicine,which provides ideas for clinical development of agents to interfere with necroptosis. 展开更多

Gastric adenosquamous carcinoma(ASC)is a rare type of gastric cancer.It is a mixed neoplasm,consisting of glandular cells and squamous cells.It is often diagnosed at an advanced stage,thus carrying a poor prognosis.We describe a case of a 73-year-old male,who presented with refractory fever and an intra-abdominal mass on imaging.He underwent a laparoscopic exploration followed by a successful totally laparoscopic total gastrectomy with D2 lymphadenectomy for gastric cancer.Postoperative pathology revealed primary gastric ASC(T4aN0M0).The patient received adjuvant radiotherapy and chemotherapy with S1 and is alive 20mo after surgery without recurrence.This is the first case of advanced gastric ASC with fever as the initial presentation treated with totally laparoscopic total gastrectomy reported in the English literature. 展开更多

Background:Intracorporeal esophagojejunostomy via a transorally inserted-anvil method during laparoscopic total gastrectomy(LTG)for upper gastric cancer has been demonstrated to be feasible,but the use of this assessment exclusively for Siewert type 2 adenocarcinoma of the esophagogastric junction(AEG)has not been reported.Methods:A total of 428 consecutive gastric-cancer patients who underwent LTG in Nanfang Hospital from January 2008 to December 2016 were reviewed.Among these patients,98 were classified as Siewert type 2 AEG.The patients underwent intracorporeal esophagojejunostomy through either a transorally inserted-anvil method(n=27)or extracorporeal anastomosis usinga circular stapler(n=71).After generating propensity scores with covariates that were associated with developing anastomotic leakage,26 patients who underwent esophagojejunostomy via the transorally inserted-anvil method(transoral group)were 1:1 matched with 26 patients who underwent the procedure via extracorporeal anastomosis using a circular stapler(extracorporeal group).The safety after 30 days post-operatively was compared between the two groups.Results:The transoral group and extracorporeal group were balanced regarding the baseline variables.The operative time,reconstruction duration,number of dissected lymph nodes,length of the proximal resectionmargins,estimated blood loss,intra-operative complication rate,and post-operative recovery course were not significantly different between the two groups.The mean anvil-insertion completion time(9.763.0 vs 13.462.0minutes,P<0.001)and the median incision length(5.5 vs 7.0 cm,P<0.001)in the transoral group were shorter than those in the extracorporeal group.The incidence of post-operative complications(26.9%vs 23.1%,P=0.749)and the classification of complication severity(P=0.939)were similar between the two groups.Conclusions:Intracorporeal esophagojejunostomy through a transorally inserted-anvil method may be a potentially safe approach to simplify and optimize the procedure during LTG for Siewert type 2 AEG. 展开更多
