ABSTRACT
Objective:To verify the transforming therapeutic efficacy of apatinib combined with oxaliplatin + tegiol (SOX regimen) in advanced gastric cancer with peritoneal metastasis.Methods:Using the method of descriptive case series study, the data of gastric cancer patients with peritoneal metastasis treated in Zhejiang Provincial People′s Hospital and Shulan (Hangzhou) Hospital from March 2016 to August 2021 were collected and treated with apatinib combined with SOX regimen. Oxaliplatin 130 mg/m 2, intravenous drip, day 1; Apatinib mesylate tablets 500 mg/d, oral, once a day, 1-21 days; Teggio: calculate the dosage according to the body surface area (<1.25 m 2, 40 mg; 1.25-1.50 m 2, 50 mg; >1.50 m 2, 60 mg). Take it orally for 1-14 days, twice a day. From the first day of chemotherapy, a cycle of 3 weeks. The short-term efficacy was evaluated every 2 cycles. After that, the multidisciplinary treatment team will decide whether the conversion operation can be accepted. When the requirements of surgical resection were met, the operation will be carried out after 1 cycle of drug withdrawal. Results:The median survival time (MST) of 23 patients was 14.1 months (95% CI: 12.3-16.4); The median overall survival (OS) after transformation therapy was 19.1 months (95% CI: 15.5-22.8). After transformation therapy, 14 cases of partial remission (PR), 3 cases of stable disease (SD) and 6 cases of progression disease (PD) in 23 patients, and the objective remission rate (ORR) was 73.9%(17/23). 12(52.2%) patients underwent surgery after transformation therapy. The 1-year OS of 12 patients was (17.0±1.5)months; Among them, 5 cases underwent R0 resection, and the R0 resection rate was 5/12. Conclusions:Transformation treatment with apatinib combined with oxaliplatin + tegio (SOX regimen) in advanced gastric cancer can achieve a high R0 resection rate with better conversion effect.

ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
Objective:To study the short-term effect of early application of intestinal microecological therapy after gastric cancer surgery.Methods:A retrospective analysis was made on 96 patients with early and middle stage gastric cancer who underwent surgical treatment in the department of gastrointestinal surgery of Shulan (Hangzhou) Hospital from June 1, 2020 to May 31, 2021. Among them, 48 patients in the observation group were given enteral nutrition support treatment in the early stage after operation and intestinal microecological preparation, while the control group of 48 patients in the early postoperative were given enteral nutrition support. The serum total protein, albumin, prealbumin and other nutrition related indexes and immune related indexes such as CD4 + , CD8 + , CD4 + /CD8 + were detected before and 7 days after operation. The clinical indexes such as the time of first anal exhaust and the incidence of infectious complications were recorded. Results:There was no significant difference between the two groups in preoperative serum total protein, albumin, prealbumin and immune related indexes such as CD4 + , CD8 + , CD4 + /CD8 + ( P>0.05). 7 days after operation, the above indexes in the observation group were significantly higher than those in the control group (all P<0.05). The anal exhaust recovery time of observation group was faster ( P<0.05); There was no significant difference in the incidence of postoperative infectious complications between the two groups ( P>0.05). Conclusions:Early application of intestinal microecological agents in patients with gastric cancer after operation can significantly improve the nutritional status and immune function, promote the recovery of intestinal function, and will not increase the incidence of complications.
ABSTRACT
The incidence rate of gastrointestinal tumors is high, and it is the most common tumor in general surgery. Due to the characteristics of the disease and surgery, patients are often accompanied by malnutrition of varying degrees during the perioperative period. This will increase the risk of operation, surgical complications and mortality, reduce the susceptibility to radiotherapy and chemotherapy and the quality of life of patients. Therefore, good perioperative nutritional screening and nutritional support treatment will effectively improve the clinical outcome of patients with gastrointestinal cancer. This article mainly introduces the progress in screening, evaluation and evaluation of nutritional status in perioperative period of gastrointestinal tumor, as well as the timing of perioperative nutritional support treatment, selection of indications and implementation methods.
ABSTRACT
Objective:To explore the role of negative pressure drainage in the treatment of duodenal stump fistula after gastrectomy.Methods:The data of 36 patients with duodenal stump fistula admitted in our department from January 2016 to January 2020 were analyzed retrospectively. According to the drainage mode of patients with intestinal fistula, the patients were divided into negative pressure drainage group (observation group) and conventional rubber tube drainage group (control group), 18 cases in each group. The incidence of complications and healing time of intestinal fistula in the two groups were observed.Results:There was no significant difference ( P>0.05) in the incidence of complications between the observation group (5.56%) and the control group (11.11%). There was a significant difference in the mean healing time between the observation group [(12.83±6.25)days] and the control group [(23.33±4.64)days] ( P<0.05). Conclusions:Negative pressure drainage is beneficial to the healing of duodenal stump fistula, and does not improve the incidence of postoperative complications. It is safe and effective. It can be used as a conventional drainage for gastrectomy.
ABSTRACT
Objective:To explore the relationship between the level of C-reactive protein/serum albumin ratio (CAR) and early postoperative anastomotic leakage in patients with colorectal cancer.Methods:From September 2016 to September 2019, all colorectal cancer patients who were treated in gastrointestinal surgery of Jinjiang hospital in Fujian Province were collected for retrospective analysis. The baseline data of the patients were collected. The blood C-reactive protein (CRP), procalcitonin (PCT) and serum albumin (ALB) were monitored on the first, third, fifth and seventh days after operation, and the results were statistically analyzed.Results:There was no significant difference in baseline data such as age, body mass index (BMI), operation time and intraoperative hemorrhage between the anastomotic leakage group and the non anastomotic leakage group ( P>0.05), but the hospitalization time of the anastomotic leakage group was longer than that of the non anastomotic leakage group ( P<0.05). The CRP level on the 3rd and PCT level on the 5th day after operation in the anastomotic leakage group were higher than those in the non anastomotic leakage group, with significant difference ( P<0.05). The CAR value on the 3rd and 5th day after operation in the anastomotic leakage group was higher than those in the non anastomotic leakage group with significant difference ( P<0.05). Conclusions:CAR can predict early anastomotic leakage in patients with colorectal cancer.
ABSTRACT
Intestinal fistula is one of the most common and serious complications of abdominal surgery and trauma. Once intestinal fistula occurs, it will produce pathological and physiological changes that are not directly related to the primary disease, leading to abdominal infection, bleeding, electrolyte imbalance, malnutrition, multiple organ dysfunction and other serious consequences, resulting in the increase of treatment difficulty, length of stay, cost of hospitalization and mortality. Therefore, it is very important to carry out prediction and early diagnosis in the early stage of intestinal fistula, and then implement comprehensive diagnosis and treatment strategy. This article mainly expounds the current situation of the diagnosis and treatment of intestinal fistula from its causes, clinical manifestations, diagnosis methods and treatment measures, and looks forward to the future treatment direction of intestinal fistula from the perspective of interdisciplinary and cross regional cooperation.

ABSTRACT
Objective This study investigated a method to rapidly inactivate tumor cells on surgical instruments intraoperatively.Methods Tumor cells were collected by immersing and washing the surgical instruments in 37 ℃ saline.The precipitation was collected by low speed centrifugation and then was cultured to harvest the tumor cells.The tumor cells were immersed in saline and distilled water of different temperatures for different duration of time.Inverted microscopy was used to investigate the changes in morphology.Results After immersion in 55 ℃ distilled water for 60 seconds,the tumor cells were swollen,the cell membranes disappeared,the sizes of the nuclei were reduced,the chromatin was condensed,and some cells lysed and separated from each other.Additionally,these tumor cells floated in the culture medium and lacked any living cells adhering to the walls of the bottle.In the group of tumor cells treated with 55 ℃ saline for 60 seconds,there were no obvious morphological changes of the tumor cell or nucleus.Conclusion The intraoperative immersion of surgical instruments in 55 ℃ distilled water for 60 seconds could completely inactivate tumor cells.
ABSTRACT
Objective To evaluate the effects of selective hepatic vascular occlusion SHVO) on the prognosis of patients undergoing hepatic resection for huge liver cancer.Methods The clinical data of 49 patients who received huge liver cancer resection at the Zhejiang People's Hospital from January 2005 to January 2010 were retrospectively analyzed.Based on the type of hepatic vascular occlusion,all patients were divided into Pringle's maneuver group (24 patients) and SHVO group (25 patients).The intraoperative condition,postoperative recovery of hepatic and renal function,incidence of complications,survival rate and recurrence rate of liver cancer of the 2 groups were compared.All data were analyzed by using the t test or Fisher exact probability.The survival curve was drawn by using the Kaplan-Meier method and the survival of the 2 groups was compared by using the Log-rank test.Results Hepatectomy was successfully performed on all the patients.Time for blood occlusion were (32 ±19) minutes in the Pringle's maneuver group and (34 ± 22)minutes in the SHVO group,with no significant difference between the 2 groups (t =2.45,P ＞ 0.05).The volume of blood loss of the Pringle's maneuver group was (736 ± 543) ml,which was significantly greater than (273 ± 298) ml of the SHVO group (t =6.87,P ＜0.05).The incidences of hepatic vein rupture were 21％ (5/24) in the Pringle's maneuver group and 24％ (6/25)in the SHVO group,with no significant difference (x2=1.45,P＞0.05).The course of 3 patients was complicated by hepatic vein rupture and hemorrhage and 1 by air embolism in the Pringle's maneuver group,while no hemorrhage or air embolism happened in the SHVO group.Four patients in the Pringle's maneuver group and 3 in the SHVO group were found with vascular invasion,while the resection margins were negative.There was no significant difference in the hepatic function in the 2 groups before operation.The levels of alanine aminotransferase in the SHVO group at postoperative day 1 and 3 were significantly lower than those in the Pringle's maneuver group (t=7.12,6.35,P ＜ 0.05).There was no significant difference in the levels of blood urea nitrogen and creatinine between the 2 groups (P ＞ 0.05).Acute hepatic dysfunction was found in 4 patients in the Pringle's maneuver group,but no patients with acute hepatic dysfunction was found in the SHVO group.The 1-and 3-year tumor-free survival rates were 58％ and 21％ in the Pringle's maneuver group,which were significantly lower than 72％ and 30％ in the SHVO group (x2 =5.32,6.07,P ＜ 0.05).The 5-year tumor-free survival rates were 21％ in the Pringle's maneuver group and 20％ in the SHVO group,with no significant difference between the 2 groups (x2 =1.78,P ＞ 0.05).Conclusion SHVO is safe,feasible and effective to prevent hemorrhage and postoperative acute hepatic dysfunction,and it is also helpful in reducing early-stage tumor recurrence and improving the tumor-free survival rate in patients with huge liver cancer.
ABSTRACT
ObjectiveTo study the proper timing for radical hepatectomy after tumour-down-staging with transcatheter arterial chemoembolization for unresectable primary liver cancer.Method This is a retrospective study of 18 patients with unresectable primary liver cancer who received radical liver resection after tumour-downstaging with transcatheter arterial chemoembolization (TACE) from January 2005 to August 2010 at Zhejiang Province People's Hospital Hepatobiliary Surgery Department.The patients received TACE 1 to 3 times (once n=4,twice n=12,and thrice n=2).After tumour-downstaging,radical liver resection was carried out (right hepatectomy,n =10 ; resection of tumour in right liver + resection of right liver metastases,n=2; resection of tumnour in right liver +radiofrequency ablation of right liver metastasis,n=1; right hepatectomy + removal of portal vein tumour thrombus,n=1 ; left hepatectomy + radiofrequency ablation of right liver metastases,n=2 ;Mesohepatectomy,n=1; and left hepatectomy + excision of liver metastasis,n=1).ResultsAfter TACE,the diameter of the primary tumour reduced by over 30％ in 6 patients (6/18,33.3％);10％～30％ in 8 patients (8/18,44.4％),and 10％ in 4 patients (4/18,22.2％).Before TACE,the tumours were not encapsulated in 6 patients (33.3％).After TACE,only 1 patient (5.6％) had the tumour remained unencapsulated.After TACE in 6 patients,the primary tumour shrunk to be within a hemiliver,and ultrasound and CT showed the tumours to have defined borders and they were away from the porta hepatis and major blood vessels.In another 6 patients,there were metastases to the contralateral hemilivers but these tumours had all shrunk in size.Selective vascular inflow and outflow occlusion technique was routinely used for liver resection.ConclusionFor primary liver cancers which are not resectable,TACE should be used first.When the tumours shrink in size,radical resectional surgery should be performed as soon as possible.The surgical technique should follow the following principles:-preserve as much normal liver parenchyma as possible,use selective vascular inflow and outflow occlusion technique to avoid ischaemia/reperfusion injury to the remnant liver,and to reduce haemorrhage.The surgery should be carried out by experienced surgeon.
ABSTRACT
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.
