PURPOSE: Enhanced recovery protocols are being implemented into the standard of care in surgical practice. This study aimed to insert a steadfast set of elements into the perioperative care pathway to establish an improved recovery program for colorectal cancer patients. METHODS: Seventy patients planned for elective laparoscopic colorectal resection were randomized into 2 groups: conventional recovery group (n = 35) and enhanced recovery group (n = 35). The primary outcome was the length of hospital stay. Secondary outcomes included the times of removal of nasogastric tubes (NGTs), successful enteral feeding, and removal of drains, postoperative complications, intra-hospital mortality, and rate of readmission. RESULTS: The mean postoperative hospital stay was 4.49 ± 0.85 days vs. 13.31 ± 6.9 days (P < 0.001), the mean time of removal of NGTs was 0.77 ± 1.031 days vs. 3.26 ± 2.737 days (P < 0.001), the mean time of successful enteral feeding was 1.89 ± 1.13 days vs. 5.46 ± 1.67 days (P < 0.001), and the mean time for removal of intra-abdominal drains was 2.94 ± 1.056 days vs. 9.06 ± 3.757 days (P < 0.001) for the enhanced and the conventional groups, respectively. Complications were significantly lower among patients in the enhanced group (25.7% vs. 65.7%) (P = 0.001). The rates of readmission were similar in the 2 groups. CONCLUSION: Applying definite evidence-based elements to the colorectal rehabilitation program significantly boosts the recovery pathway with favorable outcomes, including faster recovery of gastrointestinal tract functions, lower morbidities, and eventually earlier discharge from the hospital.

OBJECTIVETo compare clinically relevant postoperative complications after open, laparoscopic, and robotic gastrectomy for gastric cancer.

METHODSClinical data of patients with gastric cancer who underwent gastrectomy between January 1, 2014 and October 1, 2016 at Chinese People's Liberation Army General Hospital were analyzed retrospectively. All the patients were diagnosed by upper endoscopy and confirmed by biopsy without distant metastasis. They were confirmed with R0 resection by postoperative pathology. Patients with incomplete data were excluded. The complications among open group, laparoscopic group and robotic group were compared. The continuous variables were analyzed by one-way ANOVA, and categorical variables were analyzed by χtest or Fisher exact test.

RESULTSA total of 1 791 patients (1 320 males and 471 females) were included in the study, aged from 17 to 98 (59.0±11.6) years, comprising 922 open, 673 laparoscopic and 196 robotic gastrectomies. There were no significant differences among three groups in baseline data (gender, age, BMI, comorbidity, radiochemotherapy) and some of operative or postoperative data (blood transfusion, number of lymph node dissection, combined organ resection, resection site, N stage, postoperative hospital stay). The blood loss in laparoscopic and robotic groups was significantly lower than that in open group[(185.7±139.6) ml and (194.0±187.6) ml vs. (348.2±408.5) ml, F=59.924, P=0.000]. The postoperative complication occurred in 197 of 1 791(11.0%) patients. The Clavien-Dindo II(, III(a, III(b, IIII(a, and IIIII( complications were 5.5%, 4.0%, 1.2%, 0.1%, and 0.2% respectively. The anastomotic leakage (2.4%), intestinal obstruction(1.3%) and pulmonary infection(1.2%) were the three most common complications, followed by wound infection(0.8%), cardiovascular disease(0.7%), anastomotic bleeding (0.7%), delayed gastric emptying (0.6%), duodenal stump fistula(0.5%), intraperitoneal hemorrhage (0.5%), pancreatic fistula (0.3%), intra-abdominal infection(0.2%), chylous leakage (0.1%) and other complications(1.7%). There were no significant differences among three groups as the complication rates of open, laparoscopic and robotic gastrectomy were 10.6%(98/922), 10.8%(73/673) and 13.3%(26/196) respectively (χ=1.173, P=0.566). But anastomotic leakage occurred more common after laparoscopic and robotic gastrectomy compared to open gastrectomy [3.1%(21/673) and 5.1%(10/196) vs. 1.3%(12/922), χ=12.345, P=0.002]. The rate of cardiocerebral vascular diseases was higher in open group[1.3%(12/922) vs. 0.1%(1/673) and 0, χ=8.786, P=0.012]. And the rate of anastomotic bleeding was higher in robotic group [2.0%(4/196) vs. open 0.4%(4/922) and laparoscopic 0.6%(4/673), χ=6.365, P=0.041]. In view of Clavien-Dindo classification, III(a complications occurred more common in laparoscopic group [5.5%(37/673) vs. open 3.3%(30/922) and robotic 2.6%(5/196), χ=6.308, P=0.043] and III(b complications occurred more common in robotic group [3.1%(6/196) vs. open 1.1%(10/922) and laparoscopic 0.7%(5/673), χ=7.167, P=0.028].

CONCLUSIONSMorbidities of postoperative complications are comparable among open, laparoscopic and robotic gastrectomy for gastric cancer. However, in consideration of the high difficulty of anastomosis, the minimally invasive surgery should be performed by more experienced surgeons.

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.

With the development of laparoscopic techniques and equipments, laparoscopic-assisted, even total laparoscopic radical surgery for gastric cancer can be performed successfully. However, the incidence of postoperative complications is higher in the laparoscopy group as compared to the open-surgery group, which is still the barrier for the total laparoscopic radical gastrectomy. Similar to open surgery, the major complications of digestive tract reconstruction after laparoscopic radical gastrectomy are anastomotic leakage, anastomotic bleeding, anastomotic stricture and stenosis of input or output loop. Moreover, due to the lack of tactile feedback and a narrow field of vision, the laparoscopic operation may be associated with complications due to technical reasons. In clinic, we tried to reduce the incidence of these complications by improving surgical skills and strengthening the perioperative treatment of patients. According to our experience, the complications mainly occur in the early stage, and with the cumulative experience, the complications can be effectively reduced.

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.

BACKGROUND/AIMS: We evaluated the effectiveness of an endoscopic ultrasonography (EUS)-based treatment plan compared to an endoscopy-based treatment plan in selecting candidates with early gastric cancer (EGC) for endoscopic submucosal dissection based on the prediction of invasion depth. METHODS: We reviewed 393 EGCs with differentiated histology from 380 patients who underwent EUS from July 2007 to April 2010. The effectiveness of the EUS-based and endoscopy-based plans was evaluated using a simplified hypothetical treatment algorithm. RESULTS: The numbers of endoscopically determined mucosal, indeterminate, and submucosal cancers were 253 (64.4%), 56 (14.2%), and 84 (21.4%), respectively. Overall, the appropriate treatment selection rates were 75.3% (296/393) in the endoscopy-based plan and 71.5% (281/393) in the EUS-based plan (p=0.184). For endoscopic mucosal cancers, the appropriate treatment selection rates in the endoscopy-based plan were 88.1% (223/253), while the use of an EUS-based plan significantly decreased this rate to 81.4% (206/253) (p=0.036). For endoscopic submucosal cancers, the appropriate selection rates did not differ between the endoscopy-based plan (46.4%, 39/84) and the EUS-based plan (53.6%, 45/84) (p=0.070). CONCLUSIONS: EUS did not increase the likelihood of selecting the appropriate treatment in differentiated-type EGC. Therefore, EUS may not be necessary before treating differentiated-type EGC, especially in endoscopically presumed mucosal cancers.

BACKGROUNDAngiogenesis is the formation of new blood vessels to supply nutrients to tumors. Vascular endothelial growth factor (VEGF) and cluster of differentiation 34 (CD34) are important signaling proteins involved in angiogenesis. Many studies have demonstrated that VEGF and CD34 are related to tumor progression. This study focused on the relationship between VEGF, CD34, and perioperative hemorrhage in patients with gastric cancer.

METHODSTo observe the relationship between VEGF and CD34, we tracked 112 patients with advanced gastric cancer for 5 years to assess factors related to hemorrhage, using immunohistochemistry. The results were subjected to statistical analysis using a 2 × 2 contingency table, logistic regression, and receiver operating characteristic (ROC) test.

RESULTSThe concentrations of VEGF and CD34 were critically correlated with perioperative hemorrhage and neural invasion in patients with gastric cancer (P < 0.05). Expression of VEGF and CD34 was related (P < 0.05, χ2 = 6.834). VEGF and CD34 co-expression strongly increased the risk of preoperative bleeding (area under the ROC curve >0.7, P < 0.05).

CONCLUSIONSExpression of VEGF and CD34 was critically correlated with perioperative hemorrhage in gastric cancer patients. Co-expression of VEGF and CD34 could be an effective indicator for evaluating the risk of perioperative bleeding in gastric cancer patients.

OBJECTIVETo evaluate the feasibility and safety of curved cutter stapler in laparoscopic curve resection for gastric gastrointestinal stromal tumor(GIST).

METHODSA retrospective clinical study was carried out with the clinical data of 19 cases of gastric GIST, who received laparoscopic curve resection with the curved cutter stapler during the period between January 2015 and December 2015 in Department of General Surgery, Beijing Chaoyang Hospital, Capital Medical University. Curved cutter stapler was used intraoperatively to run curve resection for stomach, at least 0.5 cm away from the tumor outer margin. If the curved cutter stapler could not completely cut off the gastric wall at first time, the linear cutter stapler would be used secondly to cut off the remaining gastric wall.

RESULTSAll the cases were successfully performed under laparoscopy, without conversion to open surgery and the occurrence of severe complications. Fourteen(73.7%) patients received complete transection by the first curved cutter stapler, the other 5(26.3%) cases accepted complete transection by the second linear cutter stapler. The operative time ranged from 50 to 100(71.8±12.7) minutes, the blood loss ranged from 20 to 50 (33.6±7.4) ml, the postoperative exhaust time ranged from 1 to 4 (2.4±0.9) days, the postoperative hospital stay ranged from 5 to 9(6.8±1.1) days. There was no patient suffered from incision infection, delayed gastric emptying, anastomotic leakage and anastomotic bleeding. The postoperative pathological examination confirmed that all the cases were GIST. The tumor length ranged from 1.5 to 5.5(2.9±1.1) cm, the resection margin ranged from 0.5 to 2.0(1.2±0.4) cm and all the patients had negative resection margins. Of the 19 cases, 8(42.1%) were classified as very low risk, 5(26.3%) as low risk, 5(26.3%) as moderate risk and 1(5.3%) as high risk according to the National Institute of Health classification. Six patients with moderate and high risk were treated with imatinib. In the follow-up time of 5 to 16 months(mean 10 months) after operation, no distant metastasis and local recurrence occurred in all the cases.

CONCLUSIONThe application of curved cutter stapler in laparoscopic curve resection for GIST is safe and feasible with good short-term efficacy.

OBJECTIVETo investigate the efficacy of laparoscopic surgery in the treatment of gastrointestinal stromal tumors (GIST) in different anatomical locations.

METHODSClinical data of 133 patients with primary gastric GIST undergoing laparoscopic resection at our department from January 2006 to December 2014 were retrospectively analyzed. These patients were divided into favorable site group (F group, 90 cases), including gastric fundus, anterior wall and greater curvature of gastric body, and unfavorable site group (UF group, 43 cases),including gastroesophageal junction, posterior wall and lesser curvature of gastric body,antrum and pylorus, according to the 2014 version National Comprehensive Cancer Network Clinical Guidelines. Short-term and long-term efficacy between the two groups was compared.

RESULTSThere were no significant differences between the two groups in the general clinicopathological parameters (all P>0.05). The operation time of F group and UF group was (107.3±52.3) min and (119±53.4) min respectively (P=0.21). The blood loss in F group and UF group was (35.2±34.2) ml and (35.2±31.2) ml respectively (P=1.00). In addition, there were no significant differences in time to first fluid diet, time to first flatus, postoperative hospital stay and hospitalization expenses between the two groups(all P>0.05). In F group and UF group, morbidity of postoperative complication was 6.7%(6/90) and 4.7%(2/43) respectively (P=0.72), morbidity of category I(-II( complication was 4.4%(4/90) and 2.3%(1/43) respectively (P=0.66),and morbidity of category III(-IIII( complication was 2.2%(2/90) and 2.3% (1/43) respectively (P=1.00). Median follow-up time of all the cases was 36(1 to 84) months. The 5-year overall survival rates of F group and UF group were 93.8% and 95.2% respectively, and 5-year relapse-free survival rates were 81.1% and 89.4% respectively, without significant differences(both P>0.05).

CONCLUSIONLaparoscopic operation for gastric GIST in unfavorable sites can yield similar short- and long-term outcomes compared with those in favorable sites.

OBJECTIVETo retrospectively analyze the clinicopathology of patients with gastric gastrointestinal stromal tumor(gGIST) who underwent radical excision within 18 years in 10 domestic medical centers in order to understand the status of domestic surgical treatment of gGIST.

METHODSClinicopathological data of gGIST patients undergoing radical excision in 10 medical centers from January 1998 to January 2016 were collected, and their operational conditions, postoperative adjuvant therapy, gene detection and survival were analyzed retrospectively.

RESULTSA total of 1 846 cases were recruited in this study, including 246 cases from Guangdong General Hospital, 331 cases from Sun Yat-sen University Cancer Center, 374 cases from Union Hospital, Tongji Medical College of Huazhong University of Science and Technology, 342 cases from Nanfang Hospital of Southern Medical University, 265 cases from Fujian Medical University Union Hospital, 148 cases from Fudan University Shanghai Cancer Center, 49 cases from West China Hospital of Sichuan University, 43 cases from Peking University Cancer Hospital and Institute, 28 cases from the 81st Hospital of Pepole's Liberation Army(PLA), 20 cases from Cancer Hospital of China Medical University, Liaoning Cancer Hospital and Institute. There were 918 male (49.7%) and 928 female patients (50.3%) with median onset age of 59(18 to 95) years old. Fundus(735 cases, 39.8%) and body (781 cases, 42.3%) of stomach were the common sites of lesions. The average size of tumor was (5.3±4.6) cm. There were 1 421 cases with mitotic count ≤5(77.0%). According to the operation procedure, 924 cases (50.1%) underwent laparoscopic surgery, 759 cases (41.1%) laparotomy, 120 cases (6.5%) endoscopic surgery, and 20 cases (1.1%) laparoscopic combined with endoscopic surgery, 6 cases (0.3%) laparoscopic excision surgery through gastric wall and cavity, and 17 cases (0.9%) laparoscopy and then were transferred to laparotomy. Wedge excision were performed in 1 308 cases (70.9%), proximal gastric excision in 226 cases(12.2%), distal gastric excision in 92 cases (5.0%), total gastrectomy in 94 cases (5.1%), and local gastrectomy in 126 cases(6.8%). Multi-visceral excision was performed in 138 cases, and the splenectomy was performed in 83 cases(60.1%)with the highest ratio. According to modified NIH classification, 399 cases(21.6%) were extreme low risk, 580 cases(31.4%) were low risk, 424 cases(23.0%) were moderate risk, 443 cases (24.0%) were high risk. A total of 461 cases received postoperative imatinib adjuvant therapy, accounting for 53.2%(461/867) of patients with moderate and high risk. Among 1 846 cases, 1 402 cases (75.9%) had complete follow-up data and the median follow-up time was 33.6 (0.1 to 158) months. The 5-year survival rates of extreme low risk, low risk, moderate risk and high risk were 100%, 98.5%, 92.5%, and 79.2% with significant difference(P=0.000).

CONCLUSIONSGastric GIST occurs mostly in fundus and body of stomach in China. Wedge excision is the main operational procedure and laparoscopic operation is over 50%. General prognosis of gastric GIST is quite good.
