Objective To investigate the impact of enteral nutrition (EN) through jejunal feeding tube on the nutritional status and immunologic function of patients during chemotherapy after total gastrectomy.Methods Totally 86 patients with gastric cancer who had undergone total gastrectomy with radical resection and jejunostomy received adjuvant venous chemotherapy in our department from January 2009 to June 2010.They were divided into EN group ( n =43 ) and control group ( n =43 ) according to the hospitalization number.The EN group maintained the jejunostomy tube until the end of 6 courses of chemotherapy,and was given EN support for 7 days through jejunal tube during each course of chemotherapy; the control group removed the tube before chemotherapy without further dietary restriction or nutrition support.The nutritional and immunologic indicators on the 1 st day before chemotherapy and the 1st day after 6 chemotherapy courses were measured.ResultsThree patients in the EN group withdrew from the study because of catheter blockage or catheter loss and 2 patients in the control group failed to complete the trial because of chemotherapy side effects or economic reasons; 81 patients entered the final analysis.After 6 courses of chemotherapy,both groups experienced body weight loss,but the percentage is significantly lower in EN group than in control group (6.9％ ± 0.95％ vs.11.2％ ± 1.32％,P =0.0000).Compared with the nutritional status before the first chemotherapy,the prognosis nutritional index (PNI) in both groups declined after the 6th chemotherapy.Such decline was not statistically significant in EN group ( P =0.1534) but was significant in control group (P =0.0000).The PNI in EN group after chemotherapy was significantly higher than that in control group (P =0.0040).The levels of IgG,NK,CD4 +,and CD4 +/CD8 + were significantly higher in EN group than in control group ( P =0.0083,0.0143,0.0000,and 0.0000,respectively) after chemotherapy.ConclusionEN during postoperative chemotherapy may improve the nutritional status and immunologic function in gastric cancer patients after total gastrectomy.

Objective To explore the effect of soluble tyrosine kinase 2 fusion protein (sTie-2-Fc) on peritoneal angiogenesis, solute transport and ultrafi]tration capacity in uremic rats undergoing peritoneal dialysis (PD). Methods Thirty-two male Wistar rats were randomly divided into sham-operation group, uremic group, uremic PD group, and sTie-2-Fc group (all n=8).Uremic PD group and sTie-2-Fc group received intraperitoneal infusion of 3 ml/100 g of peritoneal dialysis fluid (PDF) containing 4.25% glucose twice daily for 4 weeks. Rats in sTie-2-Fc group were infused with PDF supplemented with 1 μg sTie-2-Fc. Before the rats were sacrificed, a peritoneal equilibration test (PET) was performed to evaluate the peritoneal solute transport and ultrafiltration capacity, and omenta was obtained for anti-CD31 immunohistochemical staining to determine the vessel density. Results Compared to their counterparts in sham-operation group,rats in uremic group had higher 2 h-dialysate to plasma creatinine concentration ratio (D/Pcr, 0.78±0.05 vs 0.70±0.09, P=0.028), lower 2 h to initial dialysate glucose concentration ratio (D/D0, 0.69±0.05 vs 0.76±0.07, P=0.033), decreased peritoneal ultrafiltration [UF, (2.29±0.50) ml vs (4.58±1.64) ml, P=0.005], and increased omental vessel density [(5.8±3.0)/HP vs (1.6±0.5)/HP, P＜0.01]. When compared to uremic group, rats in uremic PD group showed higher D/Pcr (0.89±0.05 vs 0.78±0.05, P=0.001), lower D/D0 (0.47±0.09 vs 0.69±0.05, P＜0.01), decreased UF [(0.40±0.59) ml vs (2.29±0.50) mi, P=0.005] and more omental vessels [(16.7±1.2)/HP vs (5.8±3.0)/HP, P＜0.01]. Improved peritoneal UF [(1.56±0.48) ml vs (0.40±0.59) mi, P=0.014] and decreased omental vessels [(9.2± 1.2)/HP vs (16.7 ± 1.2)/HP, P＜0.01] were observed in rats treated with sTie-2-Fc compared with those in uremic PD group, however, the differences of D/Pcr (0.87±0.06 vs 0.89±0.05, P=0.122) and D/D0 (0.60±0.11 vs 0.47±0.09, P=0.06) between these two groups did not reach statistical significance. Conclusion sTie-2-Fc preserves peritoneal ultrafiltration capacity and ameliorates peritoneal angiogenesis caused by uremia and exposure to bioincompatibal PDF.

OBJECTIVETo investigate the application of home enteral nutrition (HEN) in patients with advanced gastric cancer and its impact on the quality of life.

METHODSData of 60 consecutive patients with advanced gastric cancer, who could not underwent operation and had relapse metastasis, from June 2010 to June 2012 were retrospectively analyzed. According to familial nutritional pattern, these 60 patients were divided into HEN group (25 cases) receiving home enteral nutritional support and control group (35 cases). HEN patients were supported through jejunostomy tube or nasal gastric tube. Control patients were supported through total parental nutrition or purely eating respectively. All the patients received intravenous chemotherapy and evaluated by Karnofsky index and Spitzer system in the first, third, sixth and twelfth month. In the sixth month, patients were also examined by EORTC QLQ-C30.

RESULTSNo significant differences were found between the two groups according to 8 elements containing age, sex, BMI, etc. A total of 53 patients died within one year, including 21 in HEN group and 32 in control group. The Karnofsky scales showed that HEN group scored meanly 57.4, 39.6 and 28.2 in the third, sixth and twelfth month respectively, which were significantly higher than those of control group (45.3, 29.2 and 20.1, P=0.041, P=0.012 and P=0.015 respectively). The Spitzer scales showed that HEN group scored meanly 5.12, 4.04 and 2.54 on average in the third, sixth and twelfth month respectively, which were significantly higher than those of control group (4.32, 3.01 and 1.97, P=0.048, 0.035 and P=0.024 respectively). The EROTC QLQ-C30 scales showed that HEN group scored higher than control group in functional scales (P<0.05), and lower in the symptom scales of short breathing, pain and tired (P=0.025, P=0.044, P=0.036 respectively), while higher in diarrhea (P=0.047).

CONCLUSIONSThe quality of life of patients with advanced gastric cancer declines gradually with the nutritional status deteriorating. HEN can be applied to improve the nutritional status and quality of life.

Objective:To introduce the operation process of laparoscopic total gastrectomy assisted by small incision and gastrointestinal reconstruction using tubular instrument anastomosis in esophageal and small bowel reconstruction, and evaluate its feasibility, safety during perioperative period, and advantages of anastomosis.Methods:A total of 56 patients with gastric cancer who underwent laparoscopic total gastrectomy assisted by small incision and gastrointestinal reconstruction using tubular instrument anastomosis in esophageal and small bowel reconstruction were selected as study subjects from Zhejiang Provincial People′s Hospital between May 2022 and June 2023. Gender, age, body mass index (BMI), tumor location, tumor stage, tumor type and other related indicators were collected. The main parameters during the operation process were collected, including operation time, anastomosis time, intraoperative blood loss, postoperative recovery status, exhaust time, feeding time, complications related to anastomosis, and length of hospital stay. The differences between other digestive tract reconstruction methods such as Overlap method, reverse puncture method, and handmade anastomosis were compared and analyzed.Results:A total of 56 patients with gastric cancer were included in this study. The anastomosis time of the tubular instrument group was (42.3±15.7)min, which was superior to the handmade anastomosis group ( P<0.05). The operation time of the tubular instrument group was (176.3±25.8)min, which was superior to other methods (all P<0.05). The intraoperative blood loss of the tubular instrument group was (75.68±20.34)ml, which was less than other methods (all P<0.05). The exhaust time of the tubular instrument group was (2.6±0.2)d, which was similar to the Overlap method ( P>0.05), but earlier than the handmade anastomosis method and the reverse puncture method (all P<0.05). The incidence of anastomotic leakage in the tubular instrument group was similar to the handmade anastomosis method, the reverse puncture method, and the Overlap method (all P>0.05). There were no significant differences in postoperative hospital stay, incision infection rate, and other complications related to anastomosis between groups (all P>0.05). Conclusions:The tubular instrument anastomosis method has a shorter operation time and a smaller incision compared to traditional laparotomy surgery. It has the advantages of laparoscopic assistance with intuitive and clear visualization during the operation, while also taking into account the convenience and safety of direct visualization under laparoscopy. It is a surgical method worthy of promotion.

Objective: To evaluate the safety and feasibility of laparoscopic radical antegrade modular pancreatosplenectomy(Lap-RAMPS) for left-sided pancreatic adenocarcinoma. Methods: Clinical data of total 12 patients underwent Lap-RAMPS for left-sided pancreatic adenocarcinoma at Department of Gastrointestinal and Pancreatic Surgery, Zhejiang Provincial People′s Hospital from March 2016 to August 2017 were reviewed retrospectively.There were 7 male patients and 5 female patients, with median age of 60.5 years old(47-68 years old). Abdominal enhanced CT, pancreatic MRI, PET-CT were performed on all patients to evaluate the lesion and exclude metastasis.Follow-up were done with out-patient clinic or telephone consultancy until October 2017. Results: All patients underwent pure Lap-RAMPS.The medium operative time was 250 minutes(180-445 minutes), and the blood loss was 150 ml(50-500 ml). The medium first flatus time and diet resumption time were 3.0 days(1-5 days) and 3.5 days(1-7 days) respectively.The medium postoperative hospital stay was 9 days(4-18 days). Morbidity occurred in 8 patients with gastric empty delay(n=1), bleeding(n=1), fluid collection(n=3). There was no mortality.The medium overall number of retrived lymph nodes was 15.6 and the positive rate was 41.7%. The R0 rate was 100%.The medium follow-up was 10 months.One patient was diagnosed as liver metastasis after 8 months and accepted chemotherapy.One patient died after 14 months for tumor recurrence and metastasis.Others survived without tumor recurrence or metasitasis. Conclusion Lap-RAMPS is safe and feasible with accepted oncological outcomes for selected left side pancreatic adenocarcinoma under skilled hands.

The incidence rate and mortality rate of gastrointestinal malignant tumor are high all over the world, which seriously affects human life and health. With the continuous popularization and deepening of the concept of transformation therapy, many clinical practices, especially some multicenter clinical studies, have proved that there are still opportunities for the treatment of some advanced tumors and can obtain good survival benefits. Moreover, in recent years, a series of changes have taken place in the fields of tumor cognition, surgical technology, diagnosis, chemotherapy and biological immunotherapy, resulting in changes in the choice of tumor treatment. This paper briefly reviews the transformation treatment of advanced gastrointestinal malignant tumors in liver metastasis, lymphatic metastasis and peritoneal metastasis in recent years, in order to make the transformation treatment more scientific and standardized in practice by summarizing the relevant research results at home and abroad.

Objective:To investigate the clinical effect of enteral nutrition support in the transformation therapy of advanced gastric cancer.Methods:Eighty-two patients with advanced gastric cancer treated by transformation in Zhejiang Provincial People′s Hospital from September 2019 to August 2021 were analyzed retrospectively. 41 patients in the observation group were treated with enteral nutrition support on the basis of routine transformation treatment; 41 patients in the control group received only routine transformation treatment. The nutritional related indexes such as prealbumin, total serum protein and albumin and immune related indexes such as CD4 + , CD8 + , CD4 + /CD8 + were detected before treatment and on the 7th day after the end of 3-cycle transformation treatment, and the above indexes and transformation success rate of the two groups were compared. Results:There was no significant difference in prealbumin, total serum protein, albumin, CD4 + , CD8 + , CD4 + /CD8 + between the two groups before treatment (all P>0.05). On the 7th day after three cycles of transformation treatment, the above indexes in the observation group were higher than those in the control group, with significant difference (all P<0.05). The success rate of transformation in the observation group was higher than that in the control group ( P<0.05). Conclusions:The rational use of enteral nutrition support in the transformation treatment of patients with advanced gastric cancer can significantly improve the nutritional status and immune function of patients, increase the tolerance to chemotherapy and improve the success rate of transformation.
