ObjectiveTo evaluate the safety and efficacy of Roux-en-Y reconstruction with isolated pancreatico-jejunostomy after pancreaticoduodenectomy. MethodsSystematically literature search was performed through PubMed, EMBASE, Cochrane Library, Wanfang, VIP, and CNKI from the earliest to November 30, 2015. Randomized clinical trials (RCTs) and controlled clinical trials (CCTs) comparing outcomes of Roux-en-Y reconstruction with isolated pancrea-ticojejunostomy and conventional pancreaticojejunostomy were searched. The data were applied meta-analysis by RevMan 5.3. ResultsSeven trials were involved, two RCTs including 367 patients and five CCTs including 431 patients. Meta-analysis result showed that there was no statistic significant difference in pancreas fistula between Roux-en-Y reconstruction with isolated pancreaticojejunostomy and conventional pancreaticojejunostomy. ConclusionRoux-en-Y reconstruction with isolated pancreaticojejunostomy after pancreaticoduodenectomy is not superior to conventional pancreaticojejunostomy regarding pancreatic fistula rate or other relevant outcomes.

ObjectiveTo evaluate the metastasis feature and the dissecting value of cervicothoracic lymph node for middle esophageal squamous carcinoma. MethodsA total of 303 patients admitted to the Rugao Boai Hospital(107 patients) and the Rugao People's Hospital (196 patients) received the stapled cervical esophagogastrostomy via different thoracic approach according to the admission order number between March 2005 and February 2013. There were 290 patients with Ro resections including 149 patients by Ivor-Lewis approach (an Ivor-Lewis group) and 141 patients by Sweet approach (a Sweet group). The data of lymph nodal dissection and PTNM stage and follow-up of the two groups were analyzed. ResultsThe number of positive lymph nodes dissected from the cervicothoracic junction in the IvorLewis group was significantly greater than that in own upper abdomen (Z=3.12, P<0.05) and that in the cervicothoracic junctionin in the Sweet group (Z=3.30, P<0.05). The lymph node metastasis rate of the cervicothoracic junction in the Ivor-Lewis group was significantly higher than that in own upper abdomen(χ2=10.76, P<0.05)and that in the cervicothoracic junction in the Sweet group (χ2=7.34, P<0.05). The lymph node ratio (LNR) of the cervicothoracic junction in the Ivor-Lewis group was significantly higher than that in own upper abdomen (χ2=11.67, P<0.05) and that in the cervicothoracic junction in the Sweet group (χ2=5.99, P<0.05). The proportion of patients which PTNM were Ⅲa or Ⅲb as N>N1 in the Ivor-Lewis group was significantly higher than that in the Sweet group(χ2=5.59, P<0.05). After surgery of 1 year, 3 years, 5 years, the rate of lymph node local recurrence and the total rate of tumor metastasis or recurrence in the Ivor-Lewis group were significantly lower than in the Sweet group (P<0.05). The survival rate in the Ivor-Lewis group was significantly greater than that in the Sweet group (P<0.05). ConclusionThe cervicothoracic junction has a higher incidence of lymphatic metastasis, which transfer intensity is greater than that of upper abdomen. The extended cervicothoracic lymph node dissection should be indeed indispensible to increase of radical resection and the accuracy of PTNM stage and to improve the long term survival for middle esophageal carcinoma.
Objective To assess the effectiveness and safety of hand-suture vs. stapling anastomosis in esophagogastrostomy. Methods The following databases such as CBM (1978 to February 2012), VIP (1989 to February 2012), CNKI (1994 to February 2012), WanFang Data (1980 to February 2012), The Cochrane Library, PubMed (1966 to February 2012), EMbase (1974 to February 2012), and relevant webs of clinical trials were searched to collect the randomized controlled trials (RCTs) and quasi-RCTs about hand-suture vs. stapling anastomosis in the incidence of anastomotic leakage following esophagogastrostomy. Moreover, relevant references and grey literature were retrieved on web engines including Google Scholar and Medical Martix, and the Chinese periodicals e.g. Chinese Journal of Oncology were also handsearched. According to the inclusion and exclusion criteria, the literature, was screened, the data were extracted, and the quality of the included studies was assessed. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 9 RCTs involving 2 202 patients were included. The result of meta-analysis was as follows: the incidence of anastomotic leakage in the stapling anastomosis group was lower than that in the hand-suture anastomosis group (OR=0.43, 95%CI 0.26 to 0.71, Plt;0.01). Conclusion Stapling anastomosis is superior to hand-suture anastomosis in reducing the incidence of anastomotic leakage following esophagogastrostomy. For the limited quality and quantity of the included studies, this conclusion has to be further proved by more high-quality studies.
Objective To compare the effects of double stapling technique (DST) and single stapling technique (SST) in the low or ultralow anterior rectal resection and colon-anal canal anastomosis for patients with rectal cancer. Methods The clinical data of 351 patients with rectal caner, who were treated with low or ultralow anterior resection and colon-anal canal anastomosis in West China Hospital from Jan. 2009 to Dec. 2010, were collected and analyzed retrospectively. Operative and postoperative indexes of patients treated with DST (n=302) and SST (n=49) were compared. Results Compared with DST group, the distance from the dentate line to the edge of tumor, the length of the distal surgical margin 〔(1.83±0.59) cm vs. (2.07±0.56) cm〕, and hospitalization cost 〔(24 350.48±7 812.73) yuan vs.(29 455.32±7 869.33) yuan〕 of SST group were shorter or lower (P<0.05), but operative time was longer 〔(112.86±39.29) min vs. (100.10±36.75) min, P<0.05〕. There were no significant differences on blood loss, duration of firstambulation, duration of first passing flatus, duration of first bowel movement, duration of pulling out nasogastric tube, duration of pulling out urinary catheter, duration of pulling out drain, postoperative hospital stay, total length of hospital stay, and the incidence of complication between the 2 groups (P>0.05). All patients were in functional recovery of anal control after operation. All patients were followed-up for 6-24 months (average 16 months). During the followed-up, only 1 case suffered local tumor recurrence (SST group), 3 cases suffered distant metastases (all in DST group), and 15 cases (4.27%) died, of which 13 cases (4.30%) in DST group and 2 cases (4.08%) in SST group. Conclusions As in the low or ultralow anterior rectal resection and colon-anal canal anastomosis for patients with rectal cancer, SST results in shorter distal surgical margin than DST, so SST is suitable for the patients with shorter distance from the dentate line to the edge of tumor. What’s more, it saves the hospitalization cost effectively.
ObjectiveTo prospectively study the effect of preventing postoperative reflux esophagitis with esophagogastrostomy and RouxenY gastrojejunostomy after proximal subtotal gastrectomy.MethodsTwentysix cases of carcinoma of the gastric fundus and cardia were allocated randomly to 2 groups (the control group with 12 cases and the experimental group with 14 cases) according to odd or even number of the admission number.After proximal subtotal gastrectomy and esophagogastrostomy, the control group underwent pyloroplasty while the experimental group with pyloruspreserving RouxenY gastrojejunostomy.The inflammatory reaction of the tissue obtained at the esophagogastric junction using a fiber gastroscope was observed after half year of postoperative followup in the two groups.An examination of gastric emptying of a radionuclidelabeled test meal were performed.According to the Visick score of followup data,the effects of operation were evaluated.The 5year survival rate was also evaluated.ResultsThe postoperative gastrointestinal symptoms in the experimental group were slighter than those in the control group.The examination of gastric emptying of a radionuclidelabeled test meal showed that the gastric emptying time of a half dose,gastric remains rates of radionuclide after 10 min and 60 min in the experimental group were similar to those in the control healthy people group.But in the control group,the gastric emptying time of a half dose delayed,and the gastric remains rate of radionuclide after 10 min and 60 min were higher than the other groups.The biopsy study of the esophagogastric junction showed that the inflammatory reaction in the experimental group was slighter than that in the control group.There was no significant difference between the two groups in the survival rate.ConclusionFor patients with carcinoma of the gastric fundus and cardia, after proximal subtotal gastrectomy and esophagogastrostomy,compared with pyloroplasty,pyloruspreserving RouxenY gastrojejunostomy can decrease the reflux esophagitis,and relieve the postoperative gastrointestinal symptoms.
