Motor function was investigated by constant perfusion manometry in the Roux limb of ten patients who had undergone total gastrectomy and Roux-en-Y anastomosis. Results showed that in the fasting state, the migrating motor complex (MMC) was comletely absent, retrograde in direction or bursts of nonphasic pressure activity. Reduced motor activity patterns occurred after the meal in some patients. Four patients failed to convert fasting state into the feeding state. Total gastrectomy with Roux-en-Y anastomoses provakes a relatively severe distubance in motor function, which could contribute to postoperative upper abdominal distress.
Objective To evaluate whether jejunal interposition pouch (JIP) reconstruction is an ideal procedure of digestive tract reconstruction after total gastrectomy. Methods Ninetyfour patients after total gastrectomy had randomly divided into two groups, JIP group 42 cases and RouxenY pouch (RYP) group 52 cases. The gastrointestinal function improvement in body weight and nutritional parameters (serum albumin, hemoglobin level, and serum protein) were compared 1 year after surgery for the two groups. Results The nutritional condition of JIP group and RYP group after operation had improved (P＜0.01); and the condition of JIP group with fewer symptom problems demonstrated much more better than standard RYP group （P＜0.01）. Conclusion JIP that could obtain partly compensatory function after total gastrectomy is an ideal reconstruction.
Objective To evaluate the clinical application of modified Orr Roux-en-Y type digestive tract reconstruction. Methods Thirty-eight patients with gastric cancer were randomly classified into modified group （accepted modified Orr Roux-en-Y type digestive tract reconstruction, 18 cases） and ρ group （accepted ρ type esophagojejunostomy, 20 cases） according to the date of operation. Operative time, blood loss in operation, complications after operation, emptying time of pouch, and change of body weight before and 3 months after operation were compared between two groups. Results Compared with the ρ group 〔(283±35) min〕, the operative time of modified group 〔(229±18) min〕 was significantly shorter （Plt;0.05）. The holo-empyting time of pouch in modified group 〔(35.7±4.9) min〕 was longer than that in ρ group 〔(3.0±0.5) min〕, Plt;0.01. Blood loss in operation, complications after operation, and the body weight change had no statistical difference between two groups （Pgt;0.05）. Conclusion Modified Orr Roux-en-Y type reconstruction with a pouch function is useful in clinical application， which is not only easy to operate, but also can reduce the operative time and the complications.
Objective To investigate for a reasonable reconstruction method in patients undergoing total gastrectomy. Methods Data of 63 cases receiving total gastrectomy from January 2000 to October 2005 in Ganzhou District Hospital of Zhangye City were analyzed retrospectively, and the patients were divided into double pouch jejunum interposition （DPJI） group (n=30) and Roux-en-Y ρ pouch （RYρ） group (n=33) according to the operation methods, then operation time， morbidity of complications, amount and frequency of meat and drink, complications of digestive tract, amount of total protein and albumin were compared between two groups. Results There were no significant differences in operation time，morbidity of complications, the amount or frequency of meat and drink between two groups (Pgt;0.05); but the incidence of digestive tract complications of DPJI group was lower than that of RYρ group （P＜0.05). GradeⅠ/Ⅱof Vervaeck index and the amount of total protein and albumin in DPJI group were statistical significantly higher than those of RYρ group （P＜0.05）. Conclusion Functional DPJI is a reasonable digestive tract reconstruction method.
Objective To summarize the research progress of digestive tract reconstruction after total gastrectomy in gastric cancer. Methods The domestic and international published literatures about digestive tract reconstruction after total gastrectomy in gastric cancer were retrieved and reviewed. Results More and more attention had been paid to the postoperative quality of life after total gastrectomy in gastric cancer， and the most related factor for postoperative quality of life was the type of digestive tract reconstruction. The pouch reconstruction and preservation of enteric myoneural continuity showed beneficial effects on clinical outcomes. Current opinion considered the pouch reconstruction might be safe and effective， and was able to improve the postoperative quality of life of patients with gastric cancer. However， the preservation of duodenal pathway didn’t show significant benefits. Conclusion The optimal digestive tract reconstruction after total gastrectomy is still debating， in order to resolve the controversies， needs more in-depth fundamental researches and more high-quality randomized controlled trials.
Objectives To systematically review the efficacy and safety of Yangzhengxiaoji capsule combined with chemotherapy for malignant digestive tract tumor. Methods CNKI, WanFang Data, PubMed, EMbase, SinoMed and The Cochrane Library databases were searched online to collect randomized controlled trials (RCTs) of Yangzhengxiaoji capsule combined with chemotherapy for malignant tumor of digestive tract from inception to November 20th, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using ReMan 5.3 software. Resluts A total of 15 RCTs were included. The results of meta-analysis showed that: compared with the chemotherapy alone, Yangzhengxiaoji capsule combined with chemotherapy could significantly improve the disease control rate (RR=1.26, 95%CI 1.07 to 1.49, P<0.000 01), the clinical efficacy of TCM syndrome (RR=1.71, 95%CI 1.50 to 1.96,P<0.000 01), and the quality of life scores of patients (RR=1.44, 95%CI 1.13 to 1.82,P=0.003). The combination therapy could also improve the immune function of patients and reduce the incidence of adverse reactions. Conclusions Current evidence shows that chemotherapy combined with Yangzhengxiaoji capsule is superior to chemotherapy alone for disease control of malignant tumor of digestive tract, clinical efficacy of TCM syndrome, the quality of life, and improving immune function. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To explore the optimal technique for digestive tract reconstruction of proximal gastrectomy. Methods Fifty-nine patients who underwent proximal subtotal gastrectomy during June 2004 and January 2007 were analyzed retrospectively. All patients were divided into 2 groups according to the styles of reconstruction: one group with gastroesophagostomy (GE group) and the other with accommodation double tract digestive reconstruction of jejunal interposition (GIE group). The reconstruction of GIE group was to interposite a continuous 35 cm jejunum between the gastric stump and the oesophagus, which detail had been reported in our previous literature. The quality of life in 2 groups were evaluated and compared. Results No patient died and there was no anastomotic leakage, dumping syndrome and moderate or severe anemia occurred during perioperative period. There was no significant difference of the following indexes of nutrition between 2 groups 1 month and 6 months after operation: the value of weight, RBC, Hb, Alb, PNI and the indexes versus the preoperative ones (Pgt;0.05), for the exception of the indexes of RBC (P=0.006), Hb (P=0.001) in 1 month after operation versus the preoperative ones. The abdominal and the reflux esophagitis symptoms in GIE group were milder than those in GE group (Plt;0.001). The Visick scoring: most of the GIE group were gradeⅡ (74.2%), and grade Ⅲ (64.3%) in the GE group. There was no delay of the first time of adjuvant chemotherapy in GIE group (Pgt;0.05), and the surgical time was (0.35±0.13) h more than that of GE group (P=0.01). Conclusion The accommodation double tract digestive reconstruction of jejunal interposition for proximal subtotal gastrectomy may be safe and feasible by decreasing residual cancer cells and improving the quality of life of patients with proximal gastric carcinoma who underwent such surgical procedure.
Objective To explore the value of dual-channel anastomosis of residual stomach and jejunum in radical resection of the upper gastric cancer. Methods Forty patients with upper gastric cancer had undergone proximal gastrectomy and dualchannel digestive tract reconstruction, including esophagus-jejunum side to side anastomosis, residual stomachjejunum anastomosis, and jejunum-jejunum anastomosis. Results The cutting margin away from tumor in all the cases was more than 5 cm and no carcinoma residual. The number of lymph nodes dissection was 21±6, reaching the requirement of D2 radical surgery. There was no case appearing complications such as anastomotic leakage, obstruction or bleeding. Barium meal examination after operation showed that most of barium was directly into the jejunum, the remaining went through the duodenum into the jejunum without gastroesophageal reflux. Followed up 6-30 months with average 18 months, there were no visible reflux esophagitis in all the cases, and only 1 case appeared minor dumping syndrome. The hemoglobin increased and the quality of life was satisfactory after operation. Conclusions In regard to dual-channel anastomosis of residual stomach and jejunum, resection range is reasonable, dissection scope accords with the protocol and residual stomach has a certain pouch effect. The anastomosis has a favorable prevention from reflux esophagitis and dumping syndrome and retains the duodenum pathway, so that improves the quality of patients’ life and is a relatively ideal digestive tract reconstruction.
To investigate the effect of BMSCs on the repair of digestive tract injury and its mechanisms.Methods Recent l iterature on the effect of BMSCs on the repair of digestive tract injury was reviewed. Results BMSCs had the potency of self-repl ication, prol iferation and multipotential differentiation, which played an important role in the repair of digestive tract injury. The probable mechanisms included: BMSCs’ abil ity of migrating to the injured tissue and inhibiting the host immune response; BMSCs’ dedifferentiation and redifferentiation; BMSCs’ direct differentiation into the epithel ial cellsor the stem cells of digestive tract; BMSCs’ fusion with the stem cells or the mature epithel ial cells of digestive tract; BMSCs’ participation in the reconstruction of injured microenvironment. Conclusion BMSCs participates in the repair of digestive tract injury and has a bright future in the treatment of digestive system disease.
ObjectiveTo investigate the ideal digestive tract reconstruction method for radical distal gastrectomy (DG). MethodsClinical and follow-up data of 862 patients with gastric cancer who underwent DG in Xijing Hospital of Digestive Diseases of The Fourth Military Medical University from January 2010 to January 2013 were analyzed retrospectively. According to reconstruction methods, patients were divided into three groups:Billroth Ⅰ group (B-Ⅰgroup), Billroth Ⅱ (B-Ⅱ)+Braun group (B-Ⅱ+Braun group), and Roux-en-Y group. In order to reduce the difference of clinicopa-thological characteristics, Gmatch method was used to select patients basing on gender, age (±5 years), tumor size (±1 cm), pT staging, and pN staging. The perioperative data, recent (30 days after surgery) complications, gastroscopic results over one year, and postoperative survival rate were compared respectively among the 3 groups. Results① Perioperative indexes. The operative time, postoperative hospitalization, and semi liquid diet time were significantly different among 3 groups (P < 0.050). As compared with B-Ⅱ+Braun group and Roux-en-Y group, B-Ⅰ group had a significantly shorter operative time (P < 0.012 5), and there was no significant difference between B-Ⅱ+Braun group and Roux-en-Y group (P > 0.012 5). As compared with B-Ⅱ+Braun group, B-Ⅰ group had a significantly shorter semi liquid diet time (P < 0.012 5), but there was no significant difference between B-Ⅱ+Braun group and Roux-en-Y group, as well as Roux-en-Y group and B-Ⅰ group (P > 0.012 5). As compared with B-Ⅰ group and B-Ⅱ+Braun group, Roux-en-Y group had a significantly longer postoperative hospitalization (P < 0.012 5), and there was no significant difference between B-Ⅰ group and B-Ⅱ+ Braun group (P > 0.012 5). ② There was no significant difference in recent complications between Roux-en-Y group (12.5%, 4/32), B-Ⅱ+Braun (6.2%, 2/32), and B-Ⅰ group (3.1%, 1/32), P=0.495. ③ Results of endoscopic examination over 1 year after radical DG showed that there was significant difference among 3 groups (P < 0.050). Compared with B-Ⅰ group and B-Ⅱ+Braun group, the rates of reflux gastritis, bile reflux, and reflux esophagitis of Roux-en-Y group were all lower (P < 0.012 5), but there was no significant difference between B-Ⅰ group and B-Ⅱ+Braun group (P > 0.012 5).④ The 3-year survival rates of Roux-en-Y group, B-Ⅱ+Braun group, and B-Ⅰ group were 70.0% (21/30), 73.3% (22/30), and 75.0% (24/32) respectively, and there was no significant difference in the survival situation (P=0.911). ConclusionsThe effect of Rouxen-Y anastomosis on resisting gastrointestinal reflux is remarkable. B-Ⅰanastomosis has the advantages of more simple operation, faster recovery, and more similar to the physiological structure. Thus, B-Ⅰ anastomosis and Roux-en-Y anastomosis are recommended for digestive tract reconstruction in DG.
