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 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.
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.
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.
Objective To assess the influence of different digestive tract reconstruction on the blood glucose of gastric antral cancer patients with type 2 diabetes. Methods The clinical data of 51 cases of gastric antral cancer with type 2 diabetes treated radical surgery in this hospital from January 2006 to January 2012 were analyzed retrospectively. The patients were divided into three groups according to the different digestive tract reconstruction methods：BillrothⅠ anastomosis group （n=14）， BillrothⅡ anastomosis group （n=28）， and Roux-en-Y anastomosis group （n=9）. The indexes were analyzed and compared among three groups：① The levels of fast blood glucose （FBG） and 2h postprandial blood glucose （PG2h） were detected before operation and on 1 month and 6 months after the operation；② The level of glycated hemoglobin （HbA1c） was detected before operation and 6 months after the operation；③ The diabetes control was observed. Results The FBG and PG2h levels in the BillrothⅠ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those detected before the operation （P＞0.05）. The FBG and PG2h levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group detected on 1 month and 6 months after the operation were significantly lower than those before the operation respectively （P＜0.05）. The FBG and PG2h levels in the BillrothⅡ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those in the Roux-en-Y anastomosis group respectively （P＞0.05）， but which were markedly lower than those in the BillrothⅠ anastomosis group， the differences were statistically significant （P＜0.05）. The HbA1c levels in the BillrothⅠ anastomosis group detected before the operation and on 6 months after the operation were not statistically different from each other （P＞0.05）. The HbA1c levels in the BillrothⅡ anastomosis group and Roux-en-Y anastomosis group detected on 6 months after the operation were markedly lower than those before the operation and the difference was statistically significant （P＜0.05）. On 6 months after the operation， the HbA1c levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group were markedly lower than those in the BillrothⅠ anastomosis group and the differences were statistically significant （P＜0.05）；the HbA1c level was not statistically different between the BillrothⅡ anastomosis group and the Roux-en-Y anastomosis group （P＞0.05）. The total curative effects in the BillrothⅡ anastomosis and Roux-en-Y anastomosis groups were significantly better than those in the BillrothⅠ anastomosis group （P＜0.05）. Conclusion According to our limited clinical data， BillrothⅡ anastomosis and Roux-en-Y anastomosis for gastric antral cancer patients with type 2 diabetes may be the best surgical approach.
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.
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.
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 find out some ideal reconstructions after total gastrectomy in experimental study of rat. Methods Sixty male Sprague-Dawley rats were randomly and averagely divided into 6 groups: Roux-en-Y group (RY group), proximate jejunal pouch group (PJP group), distal jejunal pouch group (DJP group), two jejunal pouchs group (TJP group), duodenumjejunal pouch interposition group (DJPI group) and laparotomy group (L group). Body weight of rats, intestinal transit distance, adaptive changes in esophagojejunostomic mucosa and morphology changes of intestine after operation were observed and compared. Results At 2 weeks after operation, body weight in each group were significantly lower than that before operation （P＜0.05）. At 4 weeks postoperatively, body weight in PJP group, TJP group and DJPI group were significantly higher than that in RY group respectively （P＜0.05）, as well as at 8 weeks. Intestinal transit distance in PJP group was shorter than that in RY group （P＜0.05）. With regard to intestinal mucosa, TJP group and DJPI group were significantly different with RY group （P＜0.05）. Interestingly, there was no difference in each group as to refluxing esophagitis （P＞0.05）. Conclusion Proximate and two jejunal pouchs Roux-en-Y esophagojejunostomy seem to be ideal procedures for digestive tract reconstruction after total gastrectomy. The jejunal pouch interposition procedure seems to be same effective to PJP and TJP, but there is no preponderance over the former.
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.
