Objective To analyze surgical treatment and clinicopathologic features of remnant gastric cancer,and to recognize the strategies of treatment. Methods The clinical data of 26 cases patients with remnant gastric cancer diagnosed by endoscopy and pathological examination and underwent surgical treatment were retrospectively analyzed in our hospital between January 2004 and March 2011.In this study,14 cases of remnant gastric cancer from benign disease （RGCB） and 12 cases of remnant gastric cancer after stomach cancer operation （RGCC） were included.The clinical findings,Helicobacter pylori （HP） infection,surgical methods, histopathological features,and prognosis were analyzed.Results The patients developed a carcinoma in the gastric remnant about 15-44 years after operation for benign disease （median 26.3 years） and about 1-10.5 years after gastric cancer operation （median 4 years）,and there was significant differences of the two groups（P＜0.05）.HP infection of the gastric remnant was found in 73.1%（19/26） patients,and infection rate of patients was 71.4%（10/14） in RGCB and 75.0%（9/12） in RGCC, but there was no statistical different in two groups （P＞0.05）.All 26 patients underwent surgical procedure,and the rate of radical resection was 46.2% （12/26）, which was 57.1% （8/14） in RGCB and 33.3% （4/12） in RGCC respectively,there was no statistical different （P＞0.05）.Among the 12 cases underwent radical resection, the highest lymphatic metastasis rate was in No.3 group （83.3%， 10/12）,which came in second in lymph node of mesojejunum or splenic hilum （33.3%， 4/12）.Postoperative pathological staging was as follows：stageⅠin 3 cases, stageⅡ in 2 cases, stage Ⅲ in 14 cases and stage Ⅳ in 7 cases. In 18 patients underwent tumor excision,the metastasis of lymph node occurred in 13 cases （72.2%）,and the pancreas,transverse colon,or spleen were invaded in 13 cases according to histopathological results. Meanwhile,peritoneal metastasis were founded in 8 cases patients,and the peritoneal metastasis rate of patients with RGCB （14.3%；2/14） was significantly lower than that with RGCC （50.0%， 6/12）, P＜0.05.The overall one-year survival rate and three-year survival rate was 54.5% and 38.5%,respectively, and the survival time was 2-61 months （median 12 months）.Survival analysis indicated that pathological stage and radical resection were significant prognostic factors for patients with remnant gastric cancer（P＜0.01）,and radical resection was an independent prognostic factor （P＜0.05）,while age,gender,disease of first operation, degree of differentiation and HP infection were not （P＞0.05）. Conclusions Early detection and standard radical resection are the key factor to improve the prognosis of patients with remnant gastric cancer and laparoscopic exploration may minimize unnecessary injures of surgery.Because of the different clinical characteristics,strategy of treatment for RGCC and RGCB shall be discriminatory.
Objective To summarize and analyze the treatment options and prognostic factors of gastric stump carcinoma （GSC）. Methods The clinical data of 114 patients with GSC treated in The Second Affiliated Hospital of Northern Sichuan Medical College and The General Hospital of Chinese People’s Liberation Army from Mar. 2000 to May.2008 were reviewed， and influencing factors of surgical resection and prognosis were analyzed. Results For all patients，the ratios of surgical resection and curative resection（R0 resection） were 57.0%（65/114） and 54.4% （62/114）， respec-tively. The ratios of total gastrectomy， distal gastrectomy， proximal gastrectomy， endoscopic mucosal resection （EMR），and endoscopic submucosal dissection （ESD） were 73.8%（48/65）， 16.9%（11/65）， 3.1%（2/65）， 4.6%（3/65）， and 1.5%（1/65）in resection cases， and were 75.8%（47/62）， 16.1%（10/62）， 3.2%（2/62）， 4.8%（3/62）， and 0 in R0 resection cases， respectively. Seventy-five patients were followed-up for 0.3-79 months （median 12 months）， the mediansurvival time was 19.5 months， and 1-， 3-， and 5-year overall survival rates were 61.8%， 42.3%， and 30.1%， respectively. The results of multivariate analysis showed that resection rate was higher in patients with initial distalgastrectomy （P=0.002）， kps score≥80 （P=0.016）,lower macroscopic type （P=0.013）， and cM0 （P=0.000）. R0 resection （P=0.000）， macroscopic type （P=0.005）， and cT stage （P=0.006） were the independent prognostic factors. There were both no significant difference on survival between the patients with previous benign disease and those with original malignant disease when analyzed with univariate or multivariate method （P＞0.05）. There were no significant difference on overall survival curve among patients treated with palliative resection， palliative chemotherapy， simple laparotomy， and best supportive care （P＞0.05）. Conclusions The treatment options and prognosis of GSC were not influenced by the primary benign diseases or malignant diseases， and R0 resection is the most important prognostic factor. Removal of total remnant stomach is the best surgical procedure for GSC， and palliative laparotomy should be avoided.

To find the relation between the damage of gastric remnant mucosal barrier and the precancerous lesion of gastric remnant mucosa, in the process of the canine gastric remnant precarcinogenesis induced by N-methyN’-nitro-N-nitrosoguanidine (MNNG), we performed regularly the esophagogastroscopy and the mucosal biopsy.At the same time, we also measured gastric transmucosal potential difference and intracellular DNA content of remnant mucosa.We found that the more severe the damage of gastric remnant mucosal barrier was , the greater the malignant capacity of gastric remnant mucosal was.Our study suggests that the damage of gastric remnant mucosal barrier plays an important role in the gastric remnant mucosal precarcinogenesis.
Eight cases of gastric remnant carcinoma are reported and its possible etiology, course of disease, prevention and treatmant are discussed together with literature review. Duodenal ulcer, except with serious complications, should be treated conservatively. For benign gastric ulcer gastrectomy may be considered in individual case, but the operative indication can be controlled by its lesions. Regular follow-up study should be performed on patients who had gastrectomy for more than five years.
Objective To study the features of lymph node metastasis in gastric stump cancer （GSC） in order to provide the basis for the reasonable lymph node dissection in the GSC lymphadenectomy. Methods Twenty-two GSC patients accepted residual radical gastrectomy and 50 primary gastric cancer patients accepted distal D2 lymphadenectomy by the same surgeon from June 2004 to June 2012 at the department of general surgery-pediatric surgery of the People’s Hospital of Guangxi Zhuang Autonomous Region were included in this retrospective study. And the clinicopathologic factors and lymph node metastasis were compared in two groups. Results The combined organ resection rate in the primary gastric cancer patients was significantly lower than that in the GSC patients 〔14.00% （7/50） versus 54.55% （12/22），χ2=12.929，P=0.000〕. In the lymph node metastasis，the total positive rate and No.10 positive rate of lymph node metastasis in the GSC patients were significantly higher than those in the primary gastric cancer patients 〔30.56% （103/337） versus 22.13% （208/940），χ2=9.583，P=0.002；52.17% （12/23） versus 17.39% （4/23），χ2=6.133，P=0.013〕. The positive rate of lympl node micrometastasis between the GSC patients and primary gastric cancer patients was no significant difference〔2.97% （10/337） versus 1.49% （14/940），χ2=2.939，P=0.086〕 . There was 4/12 lymph node micrometastasis in the GSC patients，which was 0/4 in the primary gastric cancer patients. The positive rate of the jejunal mesentery lymph node metastasis was 35.71% （5/14） in the GSC patients. Conclusions GSC has a unique pattern in lymph node metastasis. D2 dissection and jejunsl mesentery lymph node dissection should be performed for these patients，especially，on No.10 lymph nodes. If needed，en bloc resection with invaded adjacent organs should be considered．
Objective To analyze the clinicopathologic characteristics of remnant gastric cancer （RGC）. Methods The clinical data of 114 patients with RGC treated in The Second Affiliated Hospital of Northern Sichuan MedicalCollege and The General Hospital of Chinese People’s Liberation Army from March 2000 to May 2008 were reviewed and analyzed retrospectively. The clinicopathologic characteristics between the patients with primary benign diseases and those with malignant diseases were evaluated. Results A total of 114 cases，the age was （62.6±11.3） years，and the males versus females was 4.7∶1.0. Most patients （76.2%，64/84） were diagnosed at advanced stages （consistent with pT），and the proportion of pT1 stage cases was only 23.8% （20/84），tumor invasion pT4 was 60.7% （51/84）. It was more common that tumor directly invaded adjacent organs or structures （27.4%，23/84），lymph nodes positive （42.9%，36/84），and distant metastasis （27.2%，31/114）. The location of distant metastasis was usually confined in the abdominal cavity （93.5%，29/31），and the peritoneum disseminated was the most commonly structures （67.7%，21/31）. Histologically，the incidence of poorly differentiated adenocarcinoma （76.7%，79/103） was the mostly histologic grade as well as the diffuse type （78.6%，81/103） was the mostly Laurén classification. Between the patients with primary benign diseases and those with initial malignant disease，the initial gastrectomy or the methods of reconstruction had significantly differences （both P=0.000）. The median time from initial resection to development of RGC was 30.0 years in the patients with original benign disease，contrary to 3.3 years in those with previous malignant disease （P=0.000）. Both primary diseases （benign or malignant） and the age at initial gastrectomy were the major influencing factors for the time of RGC developed （P＜0.05）. For pathohistology characters，except signet-ring cell carcinoma （P=0.045）， pT4b （P=0.049），pN stage （P=0.025），and Borrmann classification （P=0.005），there were no significant differences between the patients with previous benign diseases and those with original malignant disease，as well as the resectability rate，curative resection （R0） rate，and overall survival rate （P＞0.05）. Conclusions It is almost unaffected by originalbenign diseases or malignant diseases for clinicopathologic characteristics including the treatment option and prognostic factors.It is necessary and feasibility to form a pattern of endoscopic follow-up for RGC.
Objective To investigate the changes of gastrointestinal hormone and body composition in patients with gastric cancer after gastrectomy. Methods Thirty-eight patients with gastric cancer were divided into three groups: distal gastrectomy group, proximal gastrectomy group and total gastrectomy group and 9 volunteers as control group. The nutrition status and gastrointestinal function were evaluated by four times. The time of postoperative first anal exsufflation and defacation, hospital stay and complications were recorded, and the pre-meal and the post-meal level of gastrointestinal hormones 1 month after operation were detected. Results Compared with control group, the basic levels of somatostatin (SS), cholecystokinin (CCK) and motilin (MTL) of distal gastrectomy group, proximal gastrectomy group and total gastrectomy group significantly increased (Plt;0.01). The post-meal level of gastrointestinal hormones significantly increased as compared with the pre-meal level in each group (Plt;0.01). The CCK in proximal gastrectomy group was lower than that of distal gastrectomy group and total gastrectomy group (Plt;0.01). The postoperative body weight and body composition in each group decreased. One month after operation, patients of total gastrectomy group got the lowest body weight (Plt;0.01). The decreasing level of fat free mass (FFM) was listed by total gastrectomy group, proximal gastrectomy group and distal gastrectomy group. The edema index had significant difference in distal gastrectomy group, proximal gastrectomy group and total gastrectomy group (Plt;0.01), and total gastrectomy group was the most obvious. The postoperative passing flatus and defecation time and average hospital stay in total gastrectomy group were significantly prolonged (Plt;0.05). The gastrointestinal symptoms score among three groups was significantly different (Plt;0.05). Conclusion There are different changes of gastrointestinal hormone and body composition in patients with gastric cancer after different gastrectomy, the basic levels of SS, CCK and MTL of distal gastrectomy group, proximal gastrectomy group and total gastrectomy group are higher than those of control group. The CCK of proximal gastrectomy group is lower than that of distal gastrectomy group and total gastrectomy group. Patients received total gastrectomy lose much body weight and FFM and get higher edema index.
