Endoscopy plays an important role in the diagnosis and treatment of postoperative complications of gastric cancer. Endoscopic intervention can avoid the second operation and has attracted wide attention. Early gastric anastomotic bleeding after gastrectomy is the most common. With the development of technology, emergency endoscopy and endoscopic hemostasis provide a new treatment approach. According to the specific circumstances, endoscopists can choose metal clamp to stop bleeding, electrocoagulation hemostasis, local injection of epinephrine or sclerotherapy agents, and spraying specific hemostatic agents. Anastomotic fistula is a serious postoperative complication. In addition to endoscopically placing the small intestine nutrition tube for early enteral nutrition support treatment, endoscopic treatment, including stent, metal clip, OTSC, and Over-stitch suture system, can be chosen to close fistula. For anastomotic obstruction or stricture, endoscopic balloon or probe expansion and stent placement can be chosen. For esophageal anastomotic intractable obstruction after gastroesophageal surgery, radial incision of obstruction by the hook knife or IT knife, a new method named ERI, is a good choice. Bile leakage caused by bile duct injury can be treated by placing the stent or nasal bile duct. In addition, endoscopic methods are widely used as follows: abdominal abscess can be treated by the direct intervention under endoscopy; adhesive ileus can be treated by placing the catheter under the guidance of endoscopy to attract pressure; alkaline reflux gastritis can be rapidly diagnosed by endoscopy; gastric outlet obstruction mainly caused by cancer recurrence can be relieved by metal stent placement and the combination of endoscopy and X-ray can increase success rate; pyloric dysfunction and spasm caused by the vagus nerve injury during proximal gastrectomy can be treated by endoscopic pyloromyotomy, a new method named G-POEM, and the short-term outcomes are significant. Endoscopic submucosal dissection (ESD) allows complete resection of residual gastric precancerous lesions, however it should be performed by the experienced endoscopists.

Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.

The anastomotic complications following radical gastrectomy mainly include anastomotic leakage, anastomotic hemorrhage, and anastomotic stricture. Theanastomotic complications are not rare and remain the most common complications resulting in the perioperativedeath of patients with gastric cancer. Standardized training could let surgeons fully realize that strict selection of operative indications, thorough preoperative assessment and preparation, and refined operation in surgery are the essential measures to prevent the anastomotic complications following radical gastrectomy. In addition, identifying these complications timely and taking effective measures promptly according to the clinical context are the keys to treating these complications, reducing the treatment cycle, and decreasing the mortality.

Postoperative complications are important outcome measurements for surgical quality and safety control. However, the complication registration has always been problematic due to the lack of definition consensus and the other practical difficulties. This narrative review summarizes the data registry system for single institutional registry, national data registry, international multi-center trial registries in the western world, aiming to share the experience of complication classification and data registration. We interviewed Dr. Koh from Royal Prince Alfred Hospital in Australia for single institutional experience, Dr. van der Wielen and Dr. Desideriofor, from two international multi-center trial(STOMACH) and registry (IMIGASTRIC) respectively, and Prof. Dr. Wijnhoven from the Dutch Upper GI Audit(DUCA). The major questions include which complications are obligated to report in the respective registry, what are the definitions of those complications, who perform the registration, and how are the complications evaluated or classified. Four telephone conferences were initiated to discuss the above-mentioned topics. The DUCA and IMGASTRIC provided the definition of the major complications. The consent definition provided by DUCA was based on the LOW classification which came out after a four-year discussion and consensus meeting among international experts in the according field. However, none of the four registries asked for an obligatory standardization of the diagnostic criteria among the participating centers or surgeons. Instead, all the registries required a detailed recording of the diagnostic strategy and classification of the complications with the Clavien-Dindo scoring system. Most data were registered by surgeons or data managers during or immediately after the hospitalization. The investigators or an independent third party conducted the auditing of the data quality. Standardization of complication diagnosis among different centers is a difficult task, consuming much effort and time. On top of that, standardization of the complication registration is of critical and practical importance. We encourage all centers to register complications with the diagnostic criteria and following intervention. Based on this, the Clavien-Dindo classification can be properly justified, which has been widely accepted by most centers and should be routinely used as the standard evaluation system for postoperative complications in gastric tumor surgery.

Radical surgery of gastric cancer (D2 lymph node dissection) as the standard operation is widely used in clinical practice and satisfactory prognosis can be obtained in patients who receive radical gastrectomy. But surgical invasion can cause high morbidity of complications and mortality. The data of large-scale evidence-based medical clinical trials and large databases in Japan and Korea showed that anastomotic leakage, pancreatic leakage and abdominal abscess were the most common complications after gastrectomy, and the morbidity of complication was about 20% and mortality was about 1%. The risk factors such as elderly, obesity, and comorbidities may increase the morbidity of complications and mortality, and these factors were regarded as poor predictors after operation. Postoperative complications criteria of gastric cancer surgery is mainly used with Clavien-Dindo classification of surgical complications as international standard, and this criteria is also used in Korea. The postoperative complications are evaluated with the Common Terminology Criteria for Adverse Events (CTCAE v4.0) and Japanese Clinical Oncology Group(JCOG) postoperative complications criteria for grading definitions of postoperative complications after gastric surgery in Japan. These classifications of postoperative complications criteria were adopted widely in Japan with large-scale evidence-based medical clinical trials of gastric cancer. PS, ASA, POSSUM, E-PASS, APACHE-II(, Charison weighted index of comorbidities (WIC), Frailty Score was used in predicting postoperative mortality and morbidity in gastric cancer patients. These risk factors were assigned points in scoring systems to objectively evaluate risk of surgery, and surgical operation method was one of the risk factors on the basis of these scoring systems. We can use these scoring systems for choosing reasonable surgical methods and proper perioperative management.

Postoperative complications after gastric cancer surgery has their own specificity and complexity, and the strategies for prevention and treatment should be of equal emphasis on both theory and technology. Based on the knowledge and familiarity with different postoperative complications, to efficiently prevent them, it is not only necessary to strengthen the training of acknowledged operative strategy, smooth and precise surgical techniques, but also to address the importance of overall preoperative assessment for patients, to treat the basic diseases, and to improve and correct their general conditions. Combining with the concept and basic protocol of enhanced recovery after surgery (ERAS), it is preferred to work out an individualized perioperative preventing strategy for patients who have high risk factors of specific postoperative complications. After the operation, to guarantee intensive and individual managements for patients, to catch early abnormal signs, then to make early and precise diagnosis, and to do timely response and accurate treatments, including timely and proper re-operations, can improve the efficacy of complications and promote the recovery of patients as soon as possible.

The incidence of gastric cancer in the elderly is increasing because of increased life expectancy and improved medical care. Gastric cancer in the elderly is characterized by specific clinicopathological features, including a male-predominance gender tendency, more comorbid diseases, more advanced clinical stage, distinct histopathological findings, absence of family history, etc. The incidence of surgery-related post-operative complication shows no significant difference between elderly and non-elderly patients. However, the incidence of non-surgery-related complications is relatively higher in elderly patients. Although the overall survival rate of elderly patients is lower, the disease-specific survival rate of elderly patients is comparable with non-elderly patients. Therefore, surgery is still an effective way to improve the prognosis of elderly gastric cancer patients, and care should be taken while dealing with the comorbid diseases in elderly gastric cancer patients to improve the survival.

OBJECTIVE: To explore the prognosis and surgical method for diffuse-type advanced gastric cancer (AGC).
 METHODS: The clinicopathological data of patient, who underwent curative gastrectomy in the Second Hospital Affiliated to Lanzhou University from 2005 to 2010, were analyzed retrospectively. The prognostic factors of diffuse-type AGC were analyzed by Cox regression models. The patients were divided into a total gastrectomy group (n=120) and a subtotal gastrectomy group (n=167) according to the surgical approach. Survival rates were established by the Kaplan-Meier method and compared by the Log-rank test between the total gastrectomy group and the subtotal gastrectomy group.
 RESULTS: A total of 287 patients with diffuse-type AGC were enrolled in this study, including 120 patients in the total gastrectomy group and 167 patients in the subtotal gastrectomy group. Univariate analysis showed that the prognosis of diffuse-type AGC was associated with body mass index, number of retrieved lymph nodes, Borrmann type, tumor size, T stage, N stage, tumor-node-metastasis (TNM) stage, extent of resection, surgical margin, postoperative complication, perineural and vascular invasion (all P<0.01). Multivariate analysis showed that normal body mass index, tumor size, T stage, N stage, total gastrectomy, surgical margin, postoperative complication were the independent predictors for diffuse-type AGC (all P<0.05). The 5-year overall survival rate and progression-free survival rate for diffuse-type AGC after curative gastrectomy were 17.8% and 13.6%, respectively. The median survival time and progression-free survival of them were 22 and 18 months, respectively. The overall survival rate and progression-free survival rate in the total gastrectomy group was significantly higher than that in the subtotal gastrectomy (P<0.01); the extended extent of lymph node dissection, the lower rate of positive surgical margin and postoperative complications were present in the total gastrectomy group (all P<0.05 or P<0.01).
 CONCLUSION The patients with diffuse-type AGC have a poor prognosis. The great tumor diameter, advanced T stage, advanced N stage, subtotal gastrectomy, high rate of positive surgical margin and postoperative complication are independent risky factors for the diffuse-type AGC. However, the total gastrectomy may be beneficial to patients.

Endoscopic submucosal dissection (ESD) has been successfully performed in thrombocytopenic conditions such as in patients with liver cirrhosis but successful ESD for early gastric cancer (EGC) in hematologic diseases has rarely been reported. A 52-year-old male patient, who had previously been diagnosed with myelodysplastic syndrome 2 years ago, was admitted to our hospital for ESD of EGC. ESD was performed successfully in this patient after platelet concentrates transfusion on the day of ESD. ESD might be an option for the treatment of EGC in thrombocytopenia due to hematologic diseases when optimal supportive managements are applied.
