Beneficial effects of continual jejunal interposition after subtotal gastrectomy / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>The ideal post-gastrectomy reconstruction procedure should maintain the normal digestive function and restore intestinal transit to improve the patient quality of life. The aim of this study was to evaluate the effects of integral continual jejunal interposition after subtotal gastrectomy on the nutritional status, glucose levels, and gastric-intestinal motility.</p><p><b>METHODS</b>The study investigated the effects of the integral continual jejunal interposition, the Billroth I and Billroth II operations, and the isolated jejunal interposition following subtotal distal gastrectomy on the blood glucose, insulin, routine blood parameters, liver function, and myoelectrical activity in Beagle dogs.</p><p><b>RESULTS</b>The weights of the dogs decreased during the first post-operative weeks. Dogs in the integral continual jejunal interposition, Billroth I, and Billroth II groups gained significantly more weight by 8 weeks. The prognosis nutrition index of the dogs decreased in the first 2 post-operative weeks and increased significantly by 4 weeks in the integral continual jejunal interposition and Billroth I groups. The group with duodenal exclusion (Billroth II) had significantly higher glucose levels compared to the normal control group. The insulin curve was much higher in dogs that underwent the Billroth I, continual jejunal interposition, and isolated jejunal interposition than the Billroth II and normal groups. The frequencies of fasting and postprandial jejunal pacesetter potentials (PPs) were greater in the continual jejunal interposition and Billroth I groups than that in the isolated jejunal interposition and Billroth II groups. The percentage of aboral propagation of PPs was greater in the continual jejunal interposition group than the Billroth I, isolated jejunal interposition, and Billroth II groups.</p><p><b>CONCLUSION</b>Continual jejunal interposition after subtotal gastrectomy avoids jejunal transection, maintains the duodenal passage and food storage bags, and reduces the influence of blood glucose and insulin.</p>

Laparoscopic versus open wedge resection for gastrointestinal stromal tumors of the stomach: a clinical controlled study / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To compare the surgical outcomes between laparoscopic and open wedge resection for gastrointestinal stromal tumors of the stomach.</p><p><b>METHODS</b>Clinical data of 18 cases undergoing laparoscopic wedge resection from June 2000 to August 2009 at the Zhejiang Provincial People's Hospital were compared with 30 patients treated by open surgery. The perioperative parameters and prognosis data of the two groups were compared.</p><p><b>RESULTS</b>Compared to the open group, laparoscopic group was found with longer operative time, less blood loss, less requirement of postoperative analgesia, earlier resumption of oral intake, earlier return of first flatus, and shorter postoperative hospital stay(all P<0.05). There were no postoperative deaths in both groups. Postoperative complication rate was significantly lower in the laparoscopic group(5.5% vs. 33.3%, P<0.05). The postoperative recurrence rates were 11.8%(2/17) and 10.7%(3/28); the 5-year survival rates were 78% and 63%, respectively, and the difference was not statistically significant(P>0.05).</p><p><b>CONCLUSION</b>Laparoscopic wedge resection is a feasible treatment option for GISTs of the stomach.</p>

Oral glucose tolerance test and insulin response in Beagle dogs after subtotal distal gastrectomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate the impact of reconstruction techniques after subtotal gastrectomy on postoperative glucose and insulin levels after oral glucose tolerance test (OGTT).</p><p><b>METHODS</b>Distal gastrectomy was performed in 38 Beagle dogs. Reconstruction techniques used included integral continual jejunal interposition (n=9), Billroth I( (n=6), Billroth II( (n=7), and isolated jejunal interposition (n=8). Eight controls were used. OGTT was conducted to examine the changes in glucose and insulin levels.</p><p><b>RESULTS</b>Compared to controls, glucose significantly increased in all the 4 operative groups and peaked at 60 min. Billroth II( was associated with the most significant increase. Insulin level significantly increased in all the experimental groups in response to food stimulus and peaked at 60 min. However, the increase of insulin in Billroth II( group was not as prominent as in other groups.</p><p><b>CONCLUSIONS</b>Fluctuation of blood glucose after gastrectomy may be mitigated and insulin elevated if duodenal passage is preserved. Continual jejunal interposition should be given priority when Billroth I( reconstruction is not feasible.</p>

Effect of early enteral nutrition supplemented with glutamine on postoperative intestinal mucosal barrier function in patients with gastric carcinoma / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the effect of early enteral nutrition (EEN) supplemented with glutamine on postoperative intestinal mucosal barrier function of patients with gastric carcinoma.</p><p><b>METHODS</b>Eighty patients with gastric carcinoma who underwent intraoperative peritoneal hyperthermic chemotherapy(IPHC) were randomized into two groups: EEN+glutamine (EEN+Gln) group(n=40) and EEN group(n=40). Intestinal mucosal barrier function was evaluated by serum diamine oxidase (DAO), ratio of lactulose to mannitol(L/M), endotoxin lipopolysaccharides(LPS), and tumor necrosis factor-α(TNF-α) at 1 day before operation, 1 day, 7 days, 12 days after operation. Time to first flatus and tolerance to EEN were recorded as well.</p><p><b>RESULTS</b>There were no significant differences in the two groups in demographics(all P>0.05). Two cases(5%) in the EEN+Gln group and 1 case (2.5%) in the EEN group could not tolerate well(P>0.05). On postoperative day 1, there were no differences in serum DAO, L/M ratio, LPS, TNF-α between the two groups (P>0.05). On postoperative day 7, all the parameters for mucosal barrier function were significantly lower in the EEN+Gln group. On postoperative day 12, the urinary L/M and DAO, LPS, and TNF-α were still significantly lower in the EEN+Gln group, however, urinary L/M was comparable between the two groups. There were no differences between the two groups in the time to first flatus (P>0.05).</p><p><b>CONCLUSION</b>The immunologic tolerance of enteral nutrition supplemented with glutamine is favorable, which provides protective effect on intestinal mucosal barrier in patients with gastric carcinoma undergoing IPHC.</p>

In these patients, the healing rate was 75.0% after conservative treatment. In the 8 patients who underwent surgery, 6 were cured and 2 died (due to severe abdominal infection and multiple organ failure). A total of 30 patients had the fistulas cured and discharged.</p><p><b>CONCLUSIONS</b>Parenteral nutrition combined with enteral nutrition, succus entericus reinfusion combined with enteral nutrition, glutamine-enriched nutritional support and somatostatin are important factors for the healing of duodenocutaneous fistulas.</p>

Experimental research of integral continuous jejunal interposition after subtotal distal gastrectomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate nutritional status, myoelectrical activity, and gastrointestinal tract emptying capacity after integral continuous jejunal interposition following subtotal gastrectomy.</p><p><b>METHODS</b>According to different re-construction techniques, 30 Beagle dogs were divided into four groups after subtotal distal gastrectomy: group 1(n=9, integral continuous jejunal interposition), group 2(n=6, Billroth I(), group 3(n=7, Billroth II(), group 4(n=8, isolated jejunal interposition). Blood cell counts, liver function, myoelectrical activity and the rate of gastrointestinal tract emptying were compared among the four groups.</p><p><b>RESULTS</b>At week 12 after operation, the body weight in group 1 [(9.65±1.54) kg] was significantly higher than that in group 2[(9.25±1.76)kg], group 3[(9.31±1.54)kg] and group 4[(7.77±1.46)kg]. At week 4, the prognostic nutritional index in group 1(2671.9±49.9) was significantly higher than that in group 3(2555.9±54.7) and group 4(2440.9±54.3), but similar to that in group 2(2791.8±54.3). At week 6, the fasting and postprandial frequency of jejunal pacesetter potentials in group 1 were higher than those in group 3 and group 4(P<0.05) but comparable with those in group 2. The emptying rate of food in the four groups were 95.4%, 91.3%, 93.1% and 94.2%, respectively and there were no significant differences(P>0.05). However, as compared with group 2 and group 3, group 1 had longer operative time and later regular diet resumption, more severe abdominal adhesion(P<0.05).</p><p><b>CONCLUSION</b>Continuous jejunal interposition should be considered when Billroth I( is not feasible after subtotal gastrectomy.</p>

Clinical study on the alimentary canal reconstruction of uncutted Roux-en-Y with jejunal pouch for total gastrectomy / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the efficacy of uncutted Roux-en-Y esophagojejunostomy with jejunal pouch (URYJP) after total gastrectomy.</p><p><b>METHODS</b>Total gastrectomy was performed on 168 patients of gastric cancer, and 3 methods were used for reconstruction: the uncutted Roux-en-Y esophagojejunostomy with a jejunal pouch was performed on 69 patients(group A),Roux-en-Y esophagojejunostomy with the P-type jejunal pouch on 50 patients(group B),and Roux-en-Y esophagojejunostomy with the Orr-type jejunal pouch on 49 patients (group C). The alimentary tract reconstruction time, morbidity and mortality were compared. The 121 cases that survived for more than 1 year were analyzed for quality of life(QOL),including body weight, intake quantity, prognosis nutritional index (PNI), and Visick scores 6 and 12 months after the operations.</p><p><b>RESULTS</b>All the patients recovered quickly and no anastomosis leakage or duodenal fistulas were found. It took (30+/-7) minutes to finish the reconstruction in group A, which was significantly shorter than that in group B [(57+/-6) minutes] or in group C [(48+/-6) minutes]. There were no significant differences among 3 groups in the incidence of alkaline reflux gastritis. The incidence of Roux stasis syndrome was 2.2% in group A, which was significantly lower than 17.9% and 19.4% in group B and C. Weight loss and food intake gain in group A was superior to those in group B and C 6 months and 12 months postoperatively. As compared with prognosis nutritional index(PNI) postoperatively, those of 3 groups decreased significantly 6 months postoperatively. At 12 months after operation, the PNI of group A returned to the level before operation, while PNI of both group B and C remained significantly lower than those before operation (both P < 0.05). The Visick score of group A was superior to those of group B and C 6 months and 12 months postoperatively.</p><p><b>CONCLUSIONS</b>The new uncutted Roux operation with jejunal pouch can prevent alkaline reflux gastritis and Roux-en-Y stasis syndrome. It may be a standard procedure for reconstruction after total gastrectomy.</p>

Expression of vascular endothelial growth factor C and survivin in gastric carcinoma and their clinical implications / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the expression of vascular endothelial growth factor C (VEGF-C) and survivin protein in human gastric carcinoma,and to evaluate their clinical implications.</p><p><b>METHODS</b>The expressions of VEGF-C and survivin protein in tumor tissues,matched para- tumor tissues from 97 cases with gastric cancer and normal tissues form 20 normal controls,were determined by immunohistochemistry. Their relationships with clinicopathological parameters were analyzed.</p><p><b>RESULTS</b>The positive rate of VEGF-C and survivin protein in tumor tissues (66.0% and 57.2%) was significantly higher than those in matched para-tumor tissues normal tissues (P< 0.05). There were no significant differences in VEGF-C expression considering tumor size,localization,histological grade,venous invasion,and distant metastasis (P > 0.05), while its expression was correlated with serosal infiltration, lymphatic invasion, lymph node metastasis and TNM stage III-IV (P< 0.05). The survivin expression was significantly related with serosal infiltration,lymphatic invasion, regional lymph node metastasis,distant metastasis, and TNM stage III- IV (P< 0.05), but not with histological grade, localization,venous invasion,and tumor size (P > 0.05). The 1, 3 and 5-year survival rates of the patients with positive VEGF-C or survivin protein were significantly lower than those of the patients with negative VEGF-C or survivin (P< 0.05), respectively. In additional,the expression of VEGF-C was positively correlated with survivin expression in gastric carcinoma (P< 0.01).</p><p><b>CONCLUSION</b>The expressions of VEGF-C and/or survivin may be indicators for poor prognosis of gastric carcinoma.</p>
