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.

Roux-en-Y versus BillrothⅠreconstruction after distal gastrectomy for gastric cancer:A meta-analysis

AIM: To conduct a meta-analysis to compare Roux-en-Y (R-Y) gastrojejunostomy with gastroduodenal Billroth?I?(B-I) anastomosis after distal gastrectomy (DG) for gastric cancer.METHODS: A literature search was performed to identify studies comparing R-Y with B-I?after DG for gastric cancer from January 1990 to November 2012 in Medline, Embase, Science Citation Index Expanded and the Cochrane Central Register of Controlled Trials in The Cochrane Library. Pooled odds ratios (OR) or weighted mean differences (WMD) with 95%CI were calculated using either ?xed or random effects model. Operative outcomes such as operation time, intraoperative blood loss and postoperative outcomes such as anastomotic leakage and stricture, bile re?ux, remnant gastritis, re?ux esophagitis, dumping symptoms, delayed gastric emptying and hospital stay were the main outcomes assessed. Meta-analyses were performed using RevMan 5.0 software (Cochrane library).RESULTS: Four randomized controlled trials (RCTs) and 9 non-randomized observational clinical studies (OCS) involving 478 and 1402 patients respectively were included. Meta-analysis of RCTs revealed that R-Y reconstruction was associated with a reduced bile re?ux (OR 0.04, 95%CI: 0.01, 0.14; P < 0.00?001) and remnant gastritis (OR 0.43, 95%CI: 0.28, 0.66; P = 0.0001), however needing a longer operation time (WMD 40.02, 95%CI: 13.93, 66.11; P = 0.003). Meta-analysis of OCS also revealed R-Y reconstruction had a lower incidence of bile re?ux (OR 0.21, 95%CI: 0.08, 0.54; P = 0.001), remnant gastritis (OR 0.18, 95%CI: 0.11, 0.29; P < 0.00?001) and re?ux esophagitis (OR 0.48, 95%CI: 0.26, 0.89; P = 0.02). However, this reconstruction method was found to be associated with a longer operation time (WMD 31.30, 95%CI: 12.99, 49.60; P = 0.0008).CONCLUSION: This systematic review point towards some clinical advantages that are rendered by R-Y compared to B-I?reconstruction post DG. However there is a need for further adequately powered, well-designed RCTs comparing the same.

Progression of remnant gastric cancer is associated with duration of follow-up following distal gastrectomy

AIM： TO re-evaluate the recent clinicopathological fea- tures of remnant gastric cancer （RGC） and to develop desirable surveillance programs.METHODS： Between 1997 and 2008, 1149 patients underwent gastrectomy for gastric cancer at the Department of Digestive Surgery, Kyoto Prefectural Uni- versity of Medicine, Japan. Of these, 33 patients un- derwent gastrectomy with lymphadenectomy for RGC. Regarding the initial gastric disease, there were 19 patients with benign disease and 14 patients with gas- tric cancer. The hospital records of these patients were reviewed retrospectively. RESULTS： Concerning the initial gastric disease, the RGC group following gastric cancer had a shorter in- terval [P 〈 0.05; gastric cancer vs benign disease： 12 （2-22） vs 30 （4-51） years] and were more frequently reconstructed by Billroth- I procedure than those fol- lowing benign lesions （P 〈 0.001）. Regarding recon- struction, RGC following Billroth-]_l reconstruction showed a longer interval between surgical procedures [P 〈 0.001; Billroth-11 vs Billroth- I ： 32 （5-51） vs 12 （2-36） years] and tumors were more frequently associated with benign disease （P 〈 0.001） than those following Billroth- I reconstruction. In tumor location of RGC, after Billroth- I reconstruction, RGC occurred more fre- quently near the suture line and remnant gastric wall. After Billroth- 1I reconstruction, RGC occurred more fre- quently at the anastomotic site. The duration of follow- up was significantly associated with the stage of RGC （P 〈 0.05）. Patients diagnosed with early stage RGC such as stage Ⅰ-Ⅱ tended to have been followed up almost every second year. CONCLUSION： Meticulous follow-up examination and early detection of RGC might lead to a better prognosis. Based on the initial gastric disease and the procedure of reconstruction, an appropriate follow-up interval and programs might enable early detection of RGC.

Treatment of gastric remnant cancer post distal gastrectomy by endoscopic submucosal dissection using an insulation-tipped diathermic knife

AIM: To evaluate the effectiveness of endoscopic submucosal dissection using an insulation-tipped diathermic knife (IT-ESD) for the treatment of patients with gastric remnant cancer. METHODS: Thirty-two patients with early gastric cancer in the remnant stomach, who underwent distal gastrectomy due to gastric carcinoma, were treated with endoscopic mucosal resection (EMR) or ESD at Sumitomo Besshi Hospital and Shikoku Cancer Center in the 10-year period from January 1998 to December 2007, including 17 patients treated with IT-ESD. Retrospectively, patient backgrounds, the one-piece resection rate, complete resection (CR) rate, operation time, bleeding rate, and perforation rate were compared between patients treated with conventional EMR and those treated with IT-ESD. RESULTS: The CR rate (40% in the EMR group vs 82% in the IT-ESD group) was significantly higher in the IT-ESD group than in the EMR group; however, the operation time was significantly longer for the IT- ESD group (57.6 ± 31.9 min vs 21.1 ± 12.2 min). No significant differences were found in the rate of underlying cardiopulmonary disease (IT-ESD group, 12% vs EMR group, 13%), one-piece resection rate (100% vs 73%), bleeding rate (18% vs 6.7%), and perforation rate (0% vs 0%) between the two groups. CONCLUSION: IT-ESD appears to be an effective treatment for gastric remnant cancer post distal gastrectomy because of its high CR rate. It is useful for histological confirmation of successful treatment. Thelong-term outcome needs to be evaluated in the future.

Gastric cancer arising from the remnant stomach after distal gastrectomy:A review

Gastric stump carcinoma was initially reported by Balfore in 1922,and many reports of this disease have since been published. We herein review previous reports of gastric stump carcinoma with respect to epidemiology,carcinogenesis,Helicobacter pylori(H. pylori) infection,Epstein-Barr virus infection,clinicopathologic characteristics and endoscopic treatment. In particular,it is noteworthy that no prognostic differences are observed between gastric stump carcinoma and primary upper third gastric cancer. In addition,endoscopic submucosal dissection has recently been used to treat gastric stump carcinoma in the early stage. In contrast,many issues concerning gastric stump carcinoma remain to be clarified,including molecular biological characteristics and the carcinogenesis of H.pylori infection.We herein review the previous pertinent literature and summarize the characteristics of gastric stump carcinoma reported to date.

A comparative study of totally laparoscopic distal gastrectomy versus laparoscopic-assisted distal gastrectomy in gastric cancer patients: Short-term operative outcomes at a high-volume center

Objective： Laparoscopic gastrectomy has been established as a standard treatment for early gastric cancer, and its use is increasing recently. Compared with the conventional laparoscopy-assisted distal gastrectomy （LADG）, totally laparoscopic distal gastrectomy （TLDG） involves intracorporeal reconstruction, which can avoid the additional incision, resulting in pain reduction and early recovery. This study aimed to compare the short-term postoperative outcomes of TLDG vs. LADG in gastric cancer in a high-volume center.Methods： A retrospective cohort study was conducted on 1,322 patients who underwent laparoscopic distal gastrectomy from June 2012 to June 2017 at the National Cancer Center, Korea. LAD G was performed in the early period before July 2015, and TLDG was applied in the later period. Postoperative short-term outcomes were compared in terms of complication and clinical course between the two groups. Pain score was measured by rating the pain intensity from 0 to 10 points on postoperative day （POD） 1 and 3. Results： A total of 667 patients underwent LADG and 655 patients underwent TLDG. Clinieopathologic characteristics were not different in both groups. Intraoperative estimated blood loss （EBL） was significantly lower in the TLDG group （P〈0.001）. Postoperative pain scores were significantly lower in the TLDG group than in the LADG group on POD 1 （5.1±1.5 vs. 4.8±1.4, P=0.015）. First flatus passage after operation was significantly earlier in the TLDG group （3.4±0.8 d vs. 3.2±0.6 d, P〈0.001）. There were no differences in postoperative complications and hospital stay between the two groups. Conclusions： Based on the reported short-term postoperative outcomes, TLDG is safe and feasible as well as LADG. Moreover, compared with LADG, TLDG can reduce intraoperative EBL and postoperative pain and enhance the bowel motility in gastric cancer surgery.

Initial experience of single-incision plus one port left-side approach totally laparoscopic distal gastrectomy with uncut Roux-en-Y reconstruction

BACKGROUND Single incision plus one port left-side approach(SILS+1/L)totally laparoscopic distal gastrectomy(TLDG)is an emerging technique for the treatment of gastric cancer.Reduced port laparoscopic gastrectomy has a number of potential advantages for patients compared with conventional laparoscopic gastrectomy:relieving postoperative pain,shortening hospital stay and offering a better cosmetic outcome.Nevertheless,there are no previous reports on the use of SILS+1/L TLDG with uncut Roux-en-Y(uncut R-Y)reconstruction.AIM To investigate the initial feasibility of SILS+1/L TLDG with uncut Roux-en-Y digestive tract reconstruction(uncut R-Y reconstruction)to treat distal gastric cancer.METHODS A total of 21 patients who underwent SILS+1/L TLDG with uncut R-Y reconstruction for gastric cancer were enrolled.All patients were treated at The Second Hospital of Shandong University.Reconstructions were performed intracorporeally with 60 mm endoscopic linear stapler and 45 mm no-knife stapler.The clinicopathological characteristics,surgical details,postoperative short-term outcomes,postoperative follow-up upper gastrointestinal radiography findings and endoscopy results were analyzed retrospectively.RESULTS All SILS+1/L operations were performed by SILS+1/L TLDG successfully.The patient population included 13 men and 8 women with a mean age of 48.2 years(ranged from 40 years to 70 years)and median body mass index of 22.8 kg/m^2.There were no conversions to open laparotomy,and no other port was placed.The mean operation time was 146 min(ranged 130-180 min),and the estimated mean blood loss was 54 mL(ranged 20-110 mL).The mean duration to flatus and discharge was 2.3(ranged 1-3.5)and 7.3(ranged 6-9)d,respectively.The mean number of retrieved lymph nodes was 42(ranged 30-47).Two patients experienced mild postoperative complications,including surgical site infection(wound at the navel incision)and mild postoperative pancreatic fistula(grade A).Follow-up upper gastrointestinal radiography and endoscopy were carried out at 3 mo postoperatively.No patients experienced moderate or severe food stasis,alkaline gastritis or bile reflux during the follow-up period.No recanalization of the biliopancreatic limb was found.CONCLUSION SILS+1/L TLDG with uncut R-Y reconstruction could be safely performed as a reduced port surgery.

Prognostic value and nomograms of proximal margin distance in gastric cancer with radical distal gastrectomy

Objective:The proximal margin(PM)distance for distal gastrectomy(DG)of gastric cancer(GC)remains controversial.This study investigated the prognostic value of PM distance for survival outcomes,and aimed to combine clinicopathologic variables associated with survival outcomes after DG with different PM distance for GC into a prediction nomogram.Methods:Patients who underwent radical DG from June 2004 to June 2014 at Department of General Surgery,Nanfang Hospital,Southern Medical University were included.The first endpoints of the prognostic value of PM distance(assessed in 0.5 cm increments)for disease-free survival(DFS)and overall survival(OS)were assessed.Multivariate analysis by Cox proportional hazards regression was performed using the training set,and the nomogram was constructed,patients were chronologically assigned to the training set for dates from June 1,2004 to January 30,2012(n=493)and to the validation set from February 1,2012 to June 30,2014(n=211).Results:Among 704 patients with p TNM stage I,p TNM stage II,T1-2,T3-4,N0,differentiated type,tumor size≤5.0 cm,a PM of(2.1-5.0)cm vs.PM≤2.0 cm showed a statistically significant difference in DFS and OS,while a PM>5.0 cm was not associated with any further improvement in DFS and OS vs.a PM of 2.1-5.0 cm.In patients with p TNM stage III,N1,N2-3,undifferentiated type,tumor size>5.0 cm,the PM distance was not significantly correlated with DFS and OS between patients with a PM of(2.1-5.0)cm and a PM≤2 cm,or between patients with a PM>5.0 cm and a PM of(2.1-5.0)cm,so there were no significant differences across the three PM groups.In the training set,the C-indexes of DFS and OS,were 0.721 and 0.735,respectively,and in the validation set,the C-indexes of DFS and OS,were 0.752 and 0.751,respectively.Conclusions:It is necessary to obtain not less than 2.0 cm of PM distance in early-stage disease,while PM distance was not associated with long-term survival in later and more aggressive stages of disease because more advanced GC is a systemic disease.Different types of patients should be considered for removal of an individualized PM distance intra-operatively.We developed a universally applicable prediction model for accurately determining the 1-year,3-year and 5-year DFS and OS of GC patients according to their preoperative clinicopathologic characteristics and PM distance.

Roux-en-Y reconstruction does not require gastric decompression after radical distal gastrectomy

AIM: To determine whether routine nasogastric (NG) decompression benefitted patients undergoing radical gastric surgery. METHODS: Between January 1998 and December 2008, 519 patients who underwent distal gastrectomy for gastric cancer were retrospectively divided into 2 time-period cohorts; those treated with Billroth Ⅱ (BⅡ) reconstruction in the first 6 years and those with Roux-en-Y (RY) reconstruction in the last 5 years. In the latter group, the patients were further divided into 2 subgroups; with and without nasogastric decompression.RESULTS: Postoperatively, there were no significant differences in the number of anastomotic leaks between the 3 groups. In the tubeless RY group, time to semiliquid diet was significantly shorter than in the other 2 groups (4.4 d ± 1.4 d vs 7.2 d ± 1.3 d and 5.9 d ± 1.2 d, P = 0.005). The length of postoperative stay was significantly increased in patients with BⅡ reconstruction compared with patients with RY reconstruction with/without NG decompression (15.4 d ± 4.3 d in BⅡ group vs 12.6 d ± 3.1 d in decompressed RY and 11.4 d ± 3.4 d in the tubeless RY group, P = 0.035). The postoperative pneumonia rate was lowest in the tubeless group and highest in the BⅡ group (1.4% vs 4.6%, P = 0.01). Severe sore throat was noted in 59 (20.7%) members of the BⅡ group, 18 (17.4%) members of the decompressed RY group and 6 (4.2%) members of the tubeless RY group. Fewer patients in the tubeless group complained of severe sore throat (P = 0.001). CONCLUSION: This study provides support for abandoning routine NG decompression in patients undergoing subtotal gastrectomy with Roux-en-Y gastrojejunostomy.

Successful treatment of refractory gastric antral vascular ectasia by distal gastrectomy:A case report

Gastric antral vascular ectasia (GAVE) is an uncommon and often neglected cause of gastric hemorrhage. The treatments for GAVE include surgery, endoscopy and medical therapies. Here, we report an unusual case of GAVE. A 72-year-old man with a three-month history of recurrent melena was diagnosed with GAVE. Endoscopy revealed the classical &#x0201c;watermelon stomach&#x0201d; appearance of GAVE and complete pyloric involvement. Melena reoccurred three days after argon plasma coagulation treatment, and the level of hemoglobin dropped to 47 g/L. The patient was then successfully treated with distal gastrectomy with Billroth II anastomosis. We propose that surgery should be considered as an effective option for GAVE patients with extensive and severe lesions upon deterioration of general conditions and hemodynamic instability.

Neoadjuvant chemoradiotherapy followed by laparoscopic distal gastrectomy in advanced gastric cancer: A case report and review of literature

BACKGROUND The laparoscopic technique has been widely applied for early gastric cancer,with the advantages of minimal invasion and quick recovery.However,there is no report about the safety and oncological outcome of laparoscopic gastrectomy with D2 lymph node dissection for patients after neoadjuvant chemoradiotherapy.CASE SUMMARY A 60-year-old man was diagnosed with advanced distal gastric cancer,cT4aN1M0 stage III.The neoadjuvant chemoradiotherapy was performed based on the regimen of gross tumor volume 50G y/25 f and clinical target volume 45 Gy/25 f,as well as concurrent S-160 mg Bid.Then laparoscopic distal gastrectomy with D2 lymph node dissection was undertaken successfully for him after achieving partial response evaluated by radiological examination.The patient recovered smoothly without moderate or severe postoperative complications.The postoperative pathological stage was ypT3N0M0 with American Joint Committee on Cancer tumor regression grade 1.He was still in good condition after 5 years of follow-up.CONCLUSION Neoadjuvant chemoradiotherapy followed by laparoscopic technique could be applicable and may achieve satisfactory oncological outcomes.Our finding requires further validation by cohort studies.

Long-term outcomes of postgastrectomy syndrome after total laparoscopic distal gastrectomy using the augmented rectangle technique

BACKGROUND For total laparoscopic distal gastrectomies for gastric cancer,the reconstruction method is critical to the clinical outcome of the procedure.However,which reconstruction technique is optimal remains controversial.We originally reported the augmented rectangle technique(ART)as a reconstruction option for total laparoscopic Billroth I reconstructions.Still,little is known about its effect on long-term outcomes,specifically the incidence of postgastrectomy syndrome and its impact on quality of life.AIM To analyze postgastrectomy syndrome and quality of life after ART using the Postgastrectomy Syndrome Assessment Scale-37(PGSAS-37)questionnaire.METHODS At Juntendo University,a total of 94 patients who underwent ART for Billroth I reconstruction with total laparoscopic distal gastrectomies for gastric cancer between July 2016 and March 2020 completed the PGSAS-37 questionnaire.Multidimensional analysis was performed,comparing those 94 ART cases from our institution(ART group)to 909 distal gastrectomy cases with a Billroth I reconstruction from other Japanese institutions who also completed the PGSAS-37 as part of a larger national database(PGSAS group).RESULTS Patients in the ART group had significantly better total symptom scores in all the symptom subscales(i.e.,esophageal reflux,abdominal pain,meal-related distress,indigestion,diarrhea,constipation,and dumping).The loss of body weight was marginally greater for those in the ART group than in the PGSAS group(-9.3%vs-7.9%,P=0.054).The ART group scored significantly lower in their dissatisfaction of ongoing symptoms,during meals,and with daily life.CONCLUSION ART for Billroth I reconstruction provided beneficial long-term results for postgastrectomy syndrome and quality of life in patients undergoing total laparoscopic distal gastrectomies for gastric cancer.

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.

Laparoscopy-assisted D2 radical distal gastrectomy for advanced gastric cancer： initial experience

Background Laparoscopy-assisted radical gastrectomy is gaining acceptance for treating early gastric cancer. However, few reports concerning the effectiveness of laparoscopy-assisted D2 radical distal gastrectomy （LADG） for advanced gastric cancer or data comparing the results obtained after open distal gastrectomy （ODG） are yet available. The aim of this study was to evaluate the method, feasibility and clinical result of LADG for advanced gastric cancer. Methods A retrospective study was performed comparing LADG and ODG for advanced gastric cancer. Seventy-eight patients who underwent LADG were compared with 90 patients who underwent ODG in terms of pathologic findings, operative outcome, and complications. Results There was no conversion to open surgery in the LADG group and no postoperative mortality of any patients. There were no significant differences between LADG and ODG in operative time （（245±35） vs （220±620） minutes）, complication rate （7.7% vs 10.0%）, and number of lymph nodes （23.5±6.0 vs 21.0±7.5）, while the blood loss was less after LADG （（110±25） vs （196±30） ml, P 〈0.05）. The time to postoperative flatus and postoperative hospital stay were shorter after LADG （（73.0±8.5） vs （102.0±10.5） hours, and （8.6±1.2） vs （12.1 ±2.5） days, P 〈0.05, respectively）. Conclusion LADG for advanced gastric cancer is feasible, safe, and minimally invasive.

Post-gastrectomy spleen enlargement and esophageal varices: Distal vs total gastrectomy

AIM: To study the relationship between platelet count-to-spleen diameter ratio and post-gastrectomy esopha-geal varices (EVs) development in patients without liver cirrhosis or hepatitis. METHODS: We retrospectively studied 92 patients who underwent gastrectomy. They were divided into 2 groups on the basis of the surgical treatment: the distal gastrectomy (DG) group and total gastrectomy (TG) group. The incidence of EVs was determined and postoperative platelet counts, spleen diameters, and platelet count-to-spleen diameter ratios were com-pared between the 2 groups. RESULTS: EVs were not detected during the first 6 mo after surgery in either group; however, at 12 mo after surgery, EVs were detected in 2 patients (3%) in the DG group and in 1 patient (3.6%) in the TG group; their mean platelet count-to-spleen diameter ratio was 2628 ± 409, and 2604 ± 360, respectively.CONCLUSION: Endoscopy should be performed to detect EVs when the platelet count-to-spleen diameter ratio is < 2600.

Billroth II anastomosis combined with brown anastomosis reduce reflux gastritis in gastric cancer patients

BACKGROUND The surgeon performing a distal gastrectomy,has an arsenal of reconstruction techniques at his disposal,Billroth II among them.Braun anastomosis performed during a Billroth II procedure has shown evidence of superiority over typical Billroth II,in terms of survival,with no impact on postoperative morbidity and mortality.AIM To compare Billroth II vs Billroth II and Braun following distal gastrectomy,regarding their postoperative course.METHODS Patients who underwent distal gastrectomy during 2002-2021,were separated into two groups,depending on the surgical technique used(Billroth II:74 patients and Billroth II and Braun:28 patients).The daily output of the nasogastric tube(NGT),the postoperative day that NGT was removed and the day the patient started per os feeding were recorded.Postoperative complications were at the same time noted.Data were then statistically analyzed.RESULTS There was difference in the mean NGT removal day and the mean start feeding day.Mean total postoperative NGT output was lower in Braun group(399.17 mL vs 1102.78 mL)and it was statistically significant(P<0.0001).Mean daily postoperative NGT output was also statistically significantly lower in Braun group.According to the postoperative follow up 40 patient experienced bile reflux and alkaline gastritis from the Billroth II group,while 9 patients who underwent Christodoulidis G et al.Billroth II and Braun compared with Billroth II WJM https://www.wjgnet.com 2 March 20,2024 Volume 14 Issue 1 Billroth II and Braun anastomosis were presented with the same conditions(P<0.05).CONCLUSION There was evidence of superiority of Billroth II and Braun vs typical Billroth II in terms of bile reflux,alkaline gastritis and NGT output.

Laparoscopic gastric surgery for cancer: Where do we stand?

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.

Easy fixation effects the prevention of Peterson’s hernia and Roux stasis syndrome

BACKGROUND Laparoscopic distal gastrectomy(LDG)for gastric cancer has been progressed and popular in Japan,since it was first described in 1994.Several reconstruction methods can be adopted according to remnant stomach size,and balance of pros and cons.Roux-en-Y(R-Y)reconstruction is a one of standard options after LDG.Its complications include Petersen’s hernia and Roux stasis syndrome.Here we report our ingenious attempt,fixation of Roux limb and duodenal stump,for decreasing the development of Petersen’s hernia and Roux stasis syndrome.AIM To develop a method to decrease the development of Petersen’s hernia and Roux stasis syndrome.METHODS We performed ante-colic R-Y reconstruction after LDG.After R-Y reconstruction,we fixed Roux limb onto the duodenal stump in a smooth radian.Via this small improvement in Roux limb,Roux limb was placed to the right of the ligament of Treitz.This not only changed the anatomy of the Petersen’s defect,but it also kept a fluent direction of gastrointestinal anastomosis and avoided a cross-angle after jejunojejunostomy.31 patients with gastric cancer was performed this technique after R-Y reconstruction.Clinical parameters including clinicopathologic characteristics,perioperative outcomes,postoperative complication and follow-up data were evaluated.RESULTS The operative time was(308.0±84.6 min).This improvement method took about 10 min.Two(6.5%)patients experienced pneumonia and pancreatitis,respectively.No patient required reoperation or readmission.All patients were followed up for at least 3 year,and none of the patients developed postoperative complications related to internal hernia or Roux stasis syndrome.CONCLUSION This 10 min technique is a very effective method to decrease the development of Petersen’s hernia and Roux stasis syndrome in patients who undergo LDG.
