Objective To explore the comprehensive treatment of synchronous double cancers of the esophagus and stomach. Methods The treatment procedures of 8 patients with synchronous double cancers of the esophagus andstomach admitted in the Department of Digestive Tumor Surgery of The Hospital of Traditional Chinese Medicine of Jiangsu Province between Oct. 2006 to Feb. 2013 were analyzed. Some experience of comprehensive treatment of synch-ronous double cancers of the esophagus and stomach was explored. Results Eight cases of synchronous double cancers of the esophagus and stomach were all diagnosed by endoscopic biopsy. According to the results of CT and endoscopic ultrasonography assessment， lesions which were staged earlier than T1a were cured by endoscopic mucosal resection（6 cases， including 4 cases of esophagus cancer and 2 cases of gastric cancer）， and resection operation （1 cases of esop-hagus cancer）. The lesions staged later than T2 were treated by preoperative neoadjuvant chemoradiation， surgery， and adjuvant chemoradiation after operation （8 cases， including 2 cases of esophagus cancer and 6 cases of gastric cancer）， and simple operation （1 case）. Eight patients had been followed-up for 10-76 months （averaged 41.3 months）. Six patients survived without recurrence and metastasis during the followed-up， 1 patient died in 7 months after operation， and 1 patient relapsed in 20 months after operation. Conclusions Individually designed comprehensive treatment using neo-chemotherapy， intervention chemotherapy， radio-chemotherapy， radical resction surgery， adjuvant chemotherapy， and endoscopic mucosal resection can treat synchronous double cancers of the esophagus and stomach effectively. Impr-actical pursuit for radical surgery will not result in good prognosis
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.
ObjectiveTo explore feasibility and safety of π-shaped esophagojejunal anastomosis in totally laparoscopic total gastrectomy (TLTG).MethodThe clinical data of 20 patients who underwent TLTG, admitted in the Affiliated Hospital of Xuzhou Medical University from January 2018 to December 2018 were retrospectively analyzed.ResultsTLTG with π-shaped esophagojejunal anastomosis was successfully carried out in all 20 patients. The operative time was (236.0±55.5) min, the π-shaped esophagojejunal anastomosis time was (25.7±4.8) min, the intraoperative blood loss was (192.0±148.9) mL, the operative incision length was (3.7±0.8) cm. The postoperative pain score was 2.4±1.1, the first flatus time was (3.1±0.9) d, the first postoperative ambulation time was (1.8±0.7) d, the removal time of nasoenteral nutrution tube was (7.4±2.4) d, the liquid diet time was (6.2±1.4) d, the removal time of intraoabdominal drainage tube was (7.8±2.8) d, the postoperative hospital stay was (10.8±3.0) d. There was no death related to the anastomosis in all patients. Two patients developed a little pleural effusion and 1 patient developed lymphatic leakage were cured with conservative treatment. One patient with intraabdominal encapsulated effusion was cured by puncture and drainage treating. There was no postive incisal margin. The length of upper segment of resection form gastric cancer was (2.3±1.7) cm, the maximum tumor diameter was (4.9±2.8) cm, the number of dissected lymph nodes was 27.9±5.6. All patients were followed up 3–15 months. Eight patients underwent endoscopic examination had no obvious anastomosis stenosis and esophageal reflux. Two patients died of tumor recurrence and metastasis witnin one year after operation, and the rest had disease-free survival until the end of follow-up.ConclusionFrom preliminary results of limited cases in this study, π-shaped esophagojejunal anastomosis in TLTG is a technically safe and feasible surgical procedure in treatment of gastric cancer.
ObjectiveTo summarize the experience in the treatment of anastomotic leakage after laparoscopic D2 radical gastrectomy.MethodThe clinicopathologic data of 11 patients with anastomotic leakage after the laparoscopic D2 radical gastrectomy in the Nanchong Central Hospital from May 2016 to January 2018 were analyzed retrospectively.ResultsAmong the 11 patients with anastomotic leakage, 3 were grade Ⅱ leakages and 8 were grade Ⅲa leakages. There were no symptoms in the 3 cases of anastomotic leakage, which were confirmed only by the gastrointestinal radiography and were healed after 7 d of conservative treatment. Among the 8 patients with the clinical symptoms, 5 cases were treated by the endoscopic drainage and negative pressure suction for 60–90 d, 3 cases were treated by the endoscopic covered stent, 2 cases were cured after 30–60 d, and 1 case died of massive bleeding after 45 d.ConclusionsDue to differences of location, time, limitation, and size of anastomotic leakage after laparoscopic D2 radical gastrectomy, individualized treatment should be performed according to specific situation of patients in local treatment. Endoluminal covered stent has certain clinical application value.
Objective To compare the outcome of tubular stomach and cervical esophagus laminated anastomosis and mechanical anastomosis. Methods A total of 128 patients with middle and upper esophageal cancer in our hospital from January 2013 to January 2016 were randomly divided into two groups, 64 patients in each group and all patients underwent esophagectomy. In the group A, there were 46 males and 18 females with age of 40–75 years, treated with tubular stomach and cervical esophagus layered anastomosis. There were 51 males and 13 females with age of 43–71 years in the group B receiving mechanical anastomosis. We observed the short-term and long-term efficacy as well as complications. Results In the group A, there was cervical anastomotic fistula in 1 patient, anastomotic stenosis in 2 patients and reflux esophagitis in 12 patients. In the group B, 1 patient suffered chylothorax, 8 patients cervical anastomotic fistula, 4 patients anastomotic stenosis and 14 patients reflux esophagitis. Conclusion Layered anastomosis can effectively reduce the incidence of anastomotic fistula and stenosis. Tubular stomach can effectively prevent and reduce the reflux esophagitis, and the high long-term quality of life will be achieved after the operation.
Robotic gastric cancer surgery had developed rapidly in recent years, and its clinical application had come a long way. More and more studies had demonstrated that the robotic gastric cancer surgery was a safe and feasible procedure, and showed the technical advantages in the lymph node dissection, bleeding control, precise surgery, and postoperative recovery over laparoscopic surgery. However, some limitations such as the high surgical costs, lack of high-quality evidence, insufficient intelligence limited the development of robotic gastric cancer surgery. In the future, with more high-quality evidence-based medicine research and the development of intelligent surgical robots, the robotic gastric cancer surgery will be further standardized and promoted. We believe that robotic gastric cancer surgery will become the mainstream of minimally invasive surgery for the treatment of gastric cancer.
Objective To investigate the effect on motility function of remnant esophagus and intrathoracic stomach after esophagectomy for esophageal and cardiac carcinoma. Methods Thirty nine patients with esophageal and cardiac carcinoma were divided into two groups according to surgical procedure. Group of anastomosis above aortic arch （n = 21）： esophagogastrostomy was performed above the aortic arch in patients with esophageal carcinoma of the middle third; group of anastomosis below aortic arch（n= 18）： esophagogastrostomy was performed below the aortic arch in patients with esophageal carcinoma of the low third and cardiac carcinoma. Six health volunteers without gastroesophageal reflux were recruited as control group. Esophageal manometry and upper alimentary tract roentgenography were performed in all patients. Results There was a high pressure zone at the anastomotic orifice in parts of patients of both anastomosis groups. The resting pressure of remnant esophagus was higher than that in control group （P〈0. 05）, and similar to the resting pressure of intrathoracic stomach （P〉0. 05）. There was no significant difference in resting pressure of remnant esophagus and intrathoracic stomach between two anastomosis groups （P〉0.05）. The amplitude and number of primary peristalsis in remnant esophagus of group of anastomosis above aortic arch were significantly reduced in comparison with control group. The number of primary peristalsis in remnant esophagus of group of anastomosis above aortic arch was significantly lower than that of group of anastomosis below aortic arch （P〈0. 05）. The motility in the body of intrathoracic stomach was not observed. Weak motor activity of the gastric antrum was observed with upper alimentary tract roentgenography after surgery and evidently recovered 1 year after surgery. Conclusions The resting pressure of remnant esophagus and intrathoracic stomach is not influenced by the site of anastomosis. Esophagogastric anastomosis at the upper thorax is likely to result in poor motility of remnant esophagus. The motor activity of intrathoracic stomach becomes weak after esophagectomy and then recovers gradually over time, hut still fail to return to normal level.
Endoscopic bariatric treatment (EBT) is an effective method for the treatment of obesity. The principle of weight loss is similar to metabolic bariatric surgery. It can be classified as a food restriction (stomach-targeted) and malabsorption (small intestine-targeted). At present, a lot of EBT devices had been cleared by the US Food and Drug Administration to treat obesity, while the EBT in China lagged behind Western countries. Hence, we reviewed the current stomach-targeted EBT, aiming to provide a reference for the supplement of obesity treatment methods and the development of EBT in China.
Objective To summarize the stemness regulation mechanism of microRNA on invasion, metastasis and chemoresistance of gastric cancer stem cells (GCSCs), and to explore the anti-tumor therapy based on miRNA targeting GCSCs. Method The literatures about the research progress of miRNA and GCSCs at home and abroad in recent years were collected and reviewed. Results MiRNA could regulate a series of important cellular processes such as proliferation, apoptosis, differentiation and epithelial-mesenchymal transition of GCSCs by participating in the expression of related target genes, which was associated with poor prognosis and high mortality of gastric cancer patients. Silencing or restoring the expression of candidate miRNA of GCSCs could provide a novel and promising approach for the treatment of gastric cancer. Conclusions GCSCs have an important relationship with the malignant biological behavior of gastric cancer, and studies have confirmed that miRNA play an important regulatory role in GCSCs. Therefore, miRNA can be used as a potential target for the treatment of gastric cancer. By regulating the expression of specific miRNA, it can inhibit tumor invasion and metastasis, and improve the sensitivity of chemotherapy drugs.
ObjectiveTo compare clinical outcomes between triluminal-tube feeding combined with tubular stomach and traditional esophagectomy for the treatment of esophageal carcinoma (EC)in elderly patients. MethodsA total of 196 elderly patients (>60 years)with EC who received esophagectomy in the Department of Cardiothoracic Surgery, Mianyang Central Hospital from January 2007 to January 2013 were enrolled in this study. According to different surgical methods, all the patients were divided into triluminal-tube feeding combined with tubular stomach group (group A)and traditional esophagectomy group (group B). There were 96 patients including 51 males and 45 females in group A with their age of 60-81 (66.21±7.32)years, and 100 patients including 54 males and 46 females in group B with their age of 60-82 (65.43±6.37)years. Clinical indexes were compared between the 2 groups. ResultsRadical esophagectomy was successfully performed for all the patients. There was no statistical difference in operation time, intraoperative blood loss, postoperative incidence of chylothorax, recurrent laryngeal nerve paralysis, anastomotic leakage, anastomotic stricture or mortality between the 2 groups (P > 0.05). Time to first passage of flatus and postoperative length of hospital stay of group A were significantly shorter than those of group B, and the incidences of postoperative arrhythmias, pulmonary complications and thoracic-stomach syndrome of group A were significantly lower than those of group B (P < 0.05). ConclusionTriluminal-tube feeding combined with tubular stomach can significantly reduce postoperative morbidity, shorten hospital stay and improve quality of life of elderly patients undergoing esophagectomy.
