Magnetic compression anastomosis for reconstruction of digestive tract after total gastrectomy in beagle model

BACKGROUND Magnetic compression anastomosis(MCA)is a simple procedure contributing to a reliable anastomosis.However,digestive-tract reconstruction after total gastrectomy using MCA has not yet been reported.AIM To investigate the feasibility of MCA for simultaneous esophagojejunostomy and jejunojejunostomy after total gastrectomy using beagle dogs.METHODS Sixteen beagles were randomly divided into an MCA group(study group,n=8)and a manual-suture anastomosis group(control group,n=8).Two different magnetic anastomosis devices were used in the study group for esophagojejunal and jejunojejunal anastomoses.Both devices included a pair of circular daughter and parent magnets each.The time of esophagojejunostomy and jejunojejunostomy,postoperative complications,and survival rate of the two groups were compared.The dogs were sacrificed one month after the operation and their anastomotic specimens were obtained.Healing was observed by the naked eye and a light microscope.RESULTS Digestive-tract reconstruction after total gastrectomy was successfully completed in both groups(survival rate=100%).In the study group,esophagojejunal and jejunojejunal anastomoses took 6.13±0.58 and 4.06±0.42 min,respectively,significantly lower than those in the control group(15.63±1.53 min,P<0.001 and 10.31±1.07 min,P<0.001,respectively).Complications such as bleeding,anastomotic leakage,and anastomotic stenosis were not observed.In the study group,the magnets did not interfere with each other.Discharge time of the jejunojejunal magnetic anastomosis device was 10.75±1.28 d,while that of the esophagojejunal magnetic anastomosis device was 12.25±1.49 d.Residual silk was found in the control group.The study group showed a greater smoothness of the anastomosis than that of the control group.All layers of anastomosis healed well in both groups.CONCLUSION MCA is a safe and feasible procedure for digestive-tract reconstruction after total gastrectomy in this animal model.

Meta analysis of safety and effectiveness of anastomosis of esophagus and jejunum overlap in total laparoscopic total gastrectomy

Objective:To systematically evaluate and compare the safety and effectiveness of esophagojejunostomy and traditional esophagojejunostomy in total laparoscopic total gastrectomy in the treatment of gastric cancer,providing evidence-based medical evidence for clinical practice.Methods:PubMed,Embase,Cochrane Library,Web of Science,CNKI,Wanfang and VIP databases were searched by computer,and the retrieval time was up to December 2021.Relevant literatures were obtained,and eligible studies were gradually screened and included.Cochrane ROB bias risk assessment tool and NOS scale were used to evaluate the quality of the articles,and required data were extracted from high-quality literatures.Finally,meta-analysis was performed using Review Manager 5.3 software.Results:Eleven studies were finally included,including 1398 patients,including 566 patients receiving overlap anastomosis and 832 patients receiving traditional anastomosis.The results show that overlap anastomosis and traditional anastomosis had the advantages of operation time(MD=0.63,95%CI=7.22,8.48,P=0.88),postoperative first exhaust time(MD=-0.13,95%CI=0.43,0.18,P=0.42),postoperative first feeding time(MD=0.02,95%CI=0.33,0.37,P=0.91),anastomotic leakage(OR=1.38,95%CI=0.73,2.63,P=0.32),and postoperative hospital stay(MD=-0.16,95%CI=0.82,0.51,P=0.64)had no significant differences(all P>0.05).Compared with traditional anastomosis,overlap anastomosis had longer anastomosis time(MD=5.60,95%CI=0.59,10.62,P=0.03),higher incidence of anastomotic bleeding(OR=2.48,95%CI=1.08,5.69,P=0.03),less intraoperative bleeding(MD=-6.42,MD=-6.42,OR=2.48,95%CI=1.08,P=0.03).95%CI=10.28,-2.56,P=0.001)and anastomotic stenosis(OR=0.17,95%CI=0.06,0.46,P=0.0006).Conclusion:Overlap esophagojejunostomy is a safe,effective and prognostic surgical method,and is expected to become the standard esophagojejunostomy in total laparoscopic total gastrectomy.

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). METHODS: We selected 26 patients with gastric cancer who underwent LATG and Roux-en-Y gastrointestinal reconstruction with semi-end-to-end esophagojejunal anastomosis. RESULTS: LATG with semi-end-to-end esophagojejunal anastomosis was successfully performed in all 26 patients. The average operation time was 257 ± 36 min, with an average anastomosis time of 51 ± 17 min and an average intraoperative blood loss of 88 ± 46 mL. The average postoperative hospital stay was 8 ± 3 d. There were no complications and no mortality in this series.CONCLUSION: The application of semi-end-to-end esophagojejunal anastomosis after LATG is a safe and feasible procedure, which can be easily performed and has a short operation time in terms of anastomosis.

Full robot-assisted gastrectomy with intracorporeal robot-sewn anastomosis produces satisfying outcomes

AIM:To evaluate the feasibility and safety of full robotassisted gastrectomy with intracorporeal robot handsewn anastomosis in the treatment of gastric cancer.METHODS:From September 2011 to March 2013,110consecutive patients with gastric cancer at the authors’institution were enrolled for robotic gastrectomies.According to tumor location,total gastrectomy,distal or proximal subtotal gastrectomy with D2 lymphadenectomy was fully performed by the da Vinci Robotic Surgical System.All construction,including Roux-en-Y jejunal limb,esophagojejunal,gastroduodenal and gastrojejunal anastomoses were fully carried out by the intracorporeal robot-sewn method.At the end of surgery,the specimen was removed through a 3-4 cm incision at the umbilicus trocar point.The details of the surgical technique are well illustrated.The benefits in terms of surgical and oncologic outcomes are well documented,as well as the failure rate and postoperative complications.RESULTS:From a total of 110 enrolled patients,radical gastrectomy could not be performed in 2 patients due to late stage disease;1 patient was converted to laparotomy because of uncontrollable hemorrhage,and1 obese patient was converted due to difficult exposure;2 patients underwent extra-corporeal anastomosis by minilaparotomy to ensure adequate tumor margin.Robot-sewn anastomoses were successfully performed for 12 proximal,38 distal and 54 total gastrectomies.The average surgical time was 272.52±53.91 min and the average amount of bleeding was 80.78±32.37 mL.The average number of harvested lymph nodes was 23.1±5.3.All specimens showed adequate surgical margin.With regard to tumor staging,26,32 and 46 patients were staged asⅠ,ⅡandⅢ,respectively.The average hospitalization time after surgery was 6.2 d.One patient experienced a duodenal stump anastomotic leak,which was mild and treated conservatively.One patient was readmitted for intra-abdominal infection and was treated conservatively.Jejunal afferent loop obstruction occurred in 1 patient,who underwent re-operation and recovered quickly.CONCLUSION:This technique is feasible and can produce satisfying postoperative outcomes.It is also convenience and reliable for anastomoses in gastrectomy.Full robotic hand-sewn anastomosis may be a minimally invasive technique for gastrectomy surgery.

Proximal gastrectomy with jejunal interposition and TGRY anastomosis for proximal gastric cancer

AIM: To compare the short-term outcomes of patients who underwent proximal gastrectomy with jejunal interposition(PGJI) with those undergoing total gastrectomy with Roux-en-Y anastomosis(TGRY).METHODS: From January 2009 to January 2011, thirty-five patients underwent PGJI, and forty-one patients underwent TGRY. The surgical efficacy and short-term follow-up outcomes were compared between the two groups.RESULTS: There were no differences in the demographic and clinicopathological characteristics. The mean operation duration and postoperative hospital stay in the PGJI group were statistically longer than those in the TGRY group(P = 0.00). No anastomosis leakage was observed in two groups. No statistically significant difference was found in endoscopic findings, Visick grade or serum albumin level. The single-meal food intake in the PGJI group was more than that in the TGRY group(P = 0.00). The PG group showed significantly better hemoglobin levels in the second year(P = 0.02). The twoyear survival rate was not significantly different(PGJI vsTGRY, 93.55% vs 92.5%, P = 1.0).CONCLUSION: PGJI is a safe, radical surgical method for proximal gastric cancer and leads to better outcomes in terms of the single-meal food intake and hemoglobin level, compared with TGRY in the short term.

Assessing optimal Roux-en-Y reconstruction technique after total gastrectomy using the Postgastrectomy Syndrome Assessment Scale-45

BACKGROUND Following a total gastrectomy,patients suffer the most severe form of postgastrectomy syndrome.This is a significant clinical problem as it reduces quality of life(QOL).Roux-en-Y reconstruction,which is regarded as the gold standard for post-total gastrectomy reconstruction,can be performed using various techniques.Although the technique used could affect postoperative QOL,there are no previous reports regarding the same.AIM To investigate the effect of different techniques on postoperative QOL.The data was collected from the registry of the postgastrectomy syndrome assessment study(PGSAS).METHODS In the present study,we analyzed 393 total gastrectomy patients from those enrolled in PGSAS.Patients were divided into groups depending on whether antecolic or retrocolic jejunal elevation was performed,whether the Roux limb was“40 cm”,“shorter”(≤39 cm),or“longer”(≥41 cm),and whether the device used for esophageal and jejunal anastomosis was a circular or linear stapler.Subsequently,we comparatively investigated postoperative QOL of the patients.RESULTS Reconstruction route:Esophageal reflux subscale(SS)occurred significantly less frequently in patients who underwent antecolic reconstruction.Roux limb length:“Shorter”Roux limb did not facilitate esophageal reflux SS and somewhat attenuated indigestion SS and abdominal pain SS.Anastomosis technique:In terms of esophagojejunostomy techniques,no differences were observed.CONCLUSION The techniques used for total gastrectomy with Roux-en-Y reconstruction significantly affected postoperative symptoms.Our results suggest that elevating the Roux limb,which is not overly long,through an antecolic route may improve patients’QOL.

Totally laparoscopic total gastrectomy using the modified overlap method and conventional open total gastrectomy:A comparative study

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.

New totally intracorporeal reconstructive approach after robotic total gastrectomy: Technical details and short-term outcomes

AIM To show outcomes of our series of patients that underwent a total gastrectomy with a robotic approach and highlight the technical details of a proposed solution for the reconstruction phase.METHODS Data of gastrectomies performed from May 2014 to October 2016, were extracted and analyzed. Basic characteristics of patients, surgical and clinical outcomes were reported. The technique for reconstruction(Parisi Technique) consists on a loop of bowel shifted up antecolic to directly perform the esophago-enteric anastomosis followed by a second loop, measured up to 40 cm starting from the esojejunostomy, fixed to the biliary limb to create an enteroenteric anastomosis. The continuity between the two anastomoses is interrupted just firing a linear stapler, so obtaining the Roux-en-Y by avoiding to interrupt the mesentery.RESULTS Fifty-five patients were considered in the present analysis. Estimated blood loss was 126.55 ± 73 m L, no conversions to open surgery occurred, R0 resections were obtained in all cases. Hospital stay was 5(3-17) d, no anastomotic leakage occurred. Overall, a fast functional recovery was shown with a median of 3(3-6) d in starting a solid diet.CONCLUSION Robotic surgery and the adoption of a tailored reconstruction technique have increased the feasibility and safety of a minimally invasive approach for total gastrectomy. The present series of patients shows its implementation in a western center with satisfying short-term outcomes.

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.
