To explore the quality consistency evaluation method for multi-component traditional Chinese medicine and establish a dissolution evaluation method suitable for the characteristics of multi-component Chinese patent medicine, this study discussed the characteristics and advantages of the flow-through cell method in the dissolution evaluation of Chinese patent medicine by comparing the impact of the small cup method and the flow-through cell method on the dissolution behavior of water-soluble and lipid-soluble major active components of Danshen Tablets. Dissolution tests were performed using the small cup method as described in the 2020 edition of the Chinese Pharmacopoeia and the newly introduced flow-through cell method(closed-loop method) with water solution containing 0.5% SDS as dissolution medium. Cumulative dissolution curves of the water-soluble component salvianolic acid B and the lipid-soluble component tanshinone Ⅱ_A in Danshen Tablets were plotted, and fitting and similarity analysis of the dissolution models was conducted to identify the characteristics and advantages of the flow-through cell method. For the small cup method, 150 mL of water containing 0.5% SDS was used as the dissolution medium, with a rotation speed of 75 r·min~(-1) and a temperature of(37±0.5) ℃, and 3 mL of samples were taken at 15, 30 min, 1, 2, and 4 h, with fresh dissolution medium added at the same temperature and volume. For the flow-through cell method, a closed-loop system was used. Danshen Tablets were placed in the flow-through cell with approximately 6.7 g of glass beads, and 150 mL of water containing 0.5% SDS was used as the dissolution medium. The flow rate was set at 20 mL·min~(-1), and the temperature and sampling were the same as the small cup method. The results showed that compared with the small cup method, the flow-through cell method had stronger discriminative power and higher sensitivity in distinguishing the dissolution behavior of the two components, and could better reflect the differences in formulation quality, especially for water-insoluble lipid-soluble components. Given that there were no essential differences in the in vitro release kinetics between the two methods, the flow-through cell method could not only replace the traditional small cup method but also better guide the formulation development and identify quality issues of formulations.

Objective:To investigate the short-term outcomes of totally robotic surgical system and robotic surgical system assisted radical gastrectomy for gastric cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 290 patients who under-went robotic surgical system radical gastrectomy for gastric cancer in the First Affiliated Hospital of Army Medical University from January 2018 to November 2021 were collected. There were 208 males and 82 females, aged 58 (range, 24?84)years. Of the 290 patients, 125 patients undergoing totally robotic surgical system radical gastrectomy combined with reconstruction of digestive tract were divided into the totally robot group, and 165 patients undergoing robotic surgical system radical gastrectomy combined with a small midline incision-assisted reconstruction of digestive tract were divided into the robotic-assisted group. Observation indicators: (1) surgical and postoperative situations; (2) postoperative complications. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the non-parameter rank sum test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Results:(1) Surgical and postoperative situations. The operation time, volume of intraoperative blood loss, length of incision, duration of postoperative analgesic using, time to postoperative gastric tube removal, time to postoperative initial water intake, time to postoperative first anal flatus, duration of post-operative hospital stay were (246±43)minutes, (104±51)mL, 4(range, 3?6)cm, (2.2±0.5)days, 36(range, 10?112)hours, 62(range, 32?205)hours, 63(range, 18?138)hours, 8(range, 6?50)days in patients of the totally robot group, versus (296±59)minutes, (143±87)mL, 6(range, 3?13)cm, (3.6±0.7)days, 42(range, 12?262)hours, 90(range, 18?262)hours, 80(range, 16?295)hours, 9(range, 6?63)days in patients of the robotic-assisted group, showing significant differences in the above indicators between the two groups ( t=8.04, 4.42, Z=?13.98, t=18.46, Z=?5.47, ?5.87, ?6.14, ?4.04, P<0.05). (2) Post-operative complications.

Inflammatory bowel disease (IBD) is a formidable disease due to its complex pathogenesis. Macrophages, as a major immune cell population in IBD, are crucial for gut homeostasis. However, it is still unveiled how macrophages modulate IBD. Here, we found that LIM domain only 7 (LMO7) was downregulated in pro-inflammatory macrophages, and that LMO7 directly degraded 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) through K48-mediated ubiquitination in macrophages. As an enzyme that regulates glycolysis, PFKFB3 degradation led to the glycolytic process inhibition in macrophages, which in turn inhibited macrophage activation and ultimately attenuated murine colitis. Moreover, we demonstrated that PFKFB3 was required for histone demethylase Jumonji domain-containing protein 3 (JMJD3) expression, thereby inhibiting the protein level of trimethylation of histone H3 on lysine 27 (H3K27me3). Overall, our results indicated the LMO7/PFKFB3/JMJD3 axis is essential for modulating macrophage function and IBD pathogenesis. Targeting LMO7 or macrophage metabolism could potentially be an effective strategy for treating inflammatory diseases.

Ginger moxibustion has the effect of regulating zang-fu organs and activating qi and blood circulation. When used, ginger paste is required to be close to human skin. Currently, the ginger box used clinically in the hospital can't meet the requirement of large area fitting human skin, and the efficacy of ginger moxibustion is significantly reduced. In this study, a flexible ginger paste box was proposed, which was composed of flexible components polydimethylsiloxane (PDMS), spring and wire netting. The large flexibility of the structure made it fit well with human skin. Finite element method was used to study the fitting degree between ginger paste box and waist soft tissue. Finite element models of flexible ginger paste box and waist soft tissue were established based on Hypermesh and Abaqus software. The equivalent contact area between the flexible ginger paste box and waist was obtained by numerical simulation under different PDMS unilateral thickness, spring wire diameter, wire netting diameter and ginger paste layer thickness. The four parameters were taken as the influencing factors, and the equivalent contact area was taken as the optimization objective. The typical value analysis and variance analysis of S/N were performed by Taguchi method, and the results showed that among the four influencing factors, the wire netting diameter had the largest influence on equivalent contact area and its contribution rate reached 41.98%. The contribution rates of PDMS unilateral thickness, spring wire diameter and ginger paste layer thickness reached 36.48%, 13.97% and 6.50%, respectively. The optimized PDMS unilateral thickness, spring wire diameter, wire netting diameter and ginger paste layer thickness were 1.5, 0.4, 0.15, 35 mm, respectively, and the equivalent contact area was 95.60 cm 2. The optimized flexible ginger paste box with great fitting performance can improve the effect of ginger moxibustion.

Objective: To evaluate the influence of duodenal stump reinforcing on the short-term complications after laparoscopic radical gastrectomy. Methods: A retrospective cohort study with propensity score matching (PSM) was conducted. Clinical data of 1204 patients with gastric cancer who underwent laparoscopic radical gastrectomy at the First Affiliated Hospital of Army Medical University from April 2009 to December 2018 were collected. The digestive tract reconstruction methods included Billroth II anastomosis, Roux-en-Y anastomosis and un-cut-Roux- en-Y anastomosis. A linear stapler was used to transected the stomach and the duodenum. Among 1204 patients, 838 were males and 366 were females with mean age of (57.0±16.0) years. Duodenal stump was reinforced in 792 cases (reinforcement group) and unreinforced in 412 cases (non-reinforcement group). There were significant differences in resection range and anastomotic methods between the two groups (both P<0.001). The two groups were matched by propensity score according to the ratio of 1∶1, and the reinforcement group was further divided into purse string group and non-purse string group. The primary outcome was short-term postoperative complications (within one month after operation). Complications with Clavien-Dindo grade ≥ III a were defined as severe complications, and the morbidity of complication between the reinforcement group and the non-reinforcement group, as well as between the purse string group and the non-purse string group was compared. Results: After PSM, 411 pairs were included in the reinforcement group and the non-reinforcement group, and there were no significant differences in baseline data between the two groups (all P>0.05). No perioperative death occurred in any patient.The short-term morbidity of postoperative complication was 7.4% (61/822), including 14 cases of anastomotic leakage (23.0%), 11 cases of abdominal hemorrhage (18.0%), 8 cases of duodenal stump leakage (13.1%), 2 cases of incision dehiscence (3.3%), 6 cases of incision infection (9.8%) and 20 cases of abdominal infection (32.8%). Short-term postoperative complications were found in 25 patients (6.1%) and 36 patients (8.8%) in the reinforcement group and the non-reinforcement group, respectively, without significant difference (χ2=2.142, P=0.143). Nineteen patients (2.3%) developed short-term severe complications (Clavien-Dindo grade ≥IIIa), while no significant difference in severe complications was found between the two groups (1.7% vs. 2.9%, χ2=1.347, P=0.246). Sub-group analysis showed that the morbidity of short-term postoperative complication of the purse string group was 2.6% (9/345), which was lower than 24.2% (16/66) of the non-purse string group (χ2=45.388, P<0.001). Conclusion: Conventional reinforcement of duodenal stump does not significantly reduce the incidence of duodenal stump leakage, so it is necessary to choose whether to reinforce the duodenal stump individually, and purse string suture should be the first choice when decided to reinforce.

Objective: To compare the clinical efficacy and quality of life between uncut Roux-en-Y and Billroth II with Braun anastomosis in laparoscopic distal gastrectomy for gastric cancer patients. Methods: A retrospective cohort study was performed. Inclusion criteria: (1) 18 to 75 years old; (2) gastric cancer proved by preoperative gastroscopy, CT and pathological results and tumor was suitable for D2 radical distal gastrectomy; (3) postoperative pathological diagnosis stage was T1-4aN0-3M0 (according to the AJCC-7th TNM tumor stage), and the margin was negative; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, and American Association of Anesthesiologists (ASA) grade 1 to 3; (5) no mental illness; (6) able to answer questionnaires independently; (7) patients agreed to undergo laparoscopic distal gastrectomy and signed an informed consent. Exclusion criteria: (1) patients with severe chronic diseases and American Association of Anesthesiologists (ASA) grade >3; (2) patients with other malignant tumors; (3) patients suffered from serious mental diseases; (4) patients received neoadjuvant chemotherapy or immunotherapy. According to the above criteria, clinical data of 200 patients who underwent laparoscopic distal gastrectomy at the Department of General Surgery of the First Affiliated Hospital of Army Medical University from January 2016 to December 2019 were collected. Of the 200 patients, 108 underwent uncut Roux-en-Y anastomosis and 92 underwent Billroth II with Braun anastomosis. The general data, intraoperative and postoperative conditions, complications, and endoscopic evaluation 1 year after the surgery were compared. Besides, the quality of life of two groups was also compared using the Chinese version of the European Organization For Research and Treatment of Cancer (EORTC) quality of life questionnaire-Core 30 (QLQ-C30) and quality of life questionnaire-stomach 22 (QLQ-STO22). Results: There were no significant differences in baseline data between the two groups (all P>0.05). All the 200 patients successfully underwent laparoscopic distal gastrectomy without intraoperative complications, conversion to open surgery or perioperative death. There were no significant differences between two groups in operative time, intraoperative blood loss, postoperative complications, time to flatus, time to removal of gastric tube, time to liquid diet, time to removal of drainage tube or length of postoperative hospital stay (all P>0.05). Endoscopic evaluation was conducted 1 year after surgery. Compared to Billroth II with Braun group, the uncut Roux-en-Y group had a significantly lower incidences of gastric stasis [19.8% (17/86) vs. 37.0% (27/73), χ(2)=11.199, P=0.024], gastritis [11.6% (10/86) vs. 34.2% (25/73), χ(2)=20.892, P<0.001] and bile reflux [1.2% (1/86) vs. 28.8% (21/73), χ(2)=25.237, P<0.001], and the differences were statistically significant. The EORTC questionnaire was performed 1 year after surgery, there were no significant differences in the scores of QLQ-C30 scale between the two groups (all P>0.05), while the scores of QLQ-STO22 showed that, compared to the Billroth II with Braun group, the uncut Roux-en-Y group had a lower pain score (median: 8.3 vs. 16.7, Z=-2.342, P=0.019) and reflux score (median: 0 vs 5.6, Z=-2.284, P=0.022), and the differences were statistically significant (all P<0.05), indicating milder symptoms. Conclusion: The uncut Roux-en-Y anastomosis is safe and reliable in laparoscopic distal gastrectomy, which can reduce the incidences of gastric stasis, gastritis and bile reflux, and improve the quality of life of patients after surgery.

Of the 85 patients, 46 patients undergoing laparoscopic total gastrectomy+ D 2 lymphadenectomy+ semi-end-to-end esophagojejunal anastomosis were allocated into semi-end-to-end anastomosis group, and 39 patients undergoing laparoscopic radical total gastrectomy+ D 2 lymphadenectomy+ side-to-side esophagojejunal anastomosis were allocated into side-to-side anastomosis group. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was performed by outpatient examination and telephone interview to detect the survival, anastomotic stenosis and tumor recurrence at postoperative one year up to January 2020. Measurement data with normal distribution were expressed as Mean± SD, and comparison between groups was analyzed using the t test. Count data were expressed as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ranked data was analyzed using the nonparametric rank sum test. Results:(1) Surgical situations: patients of two groups successfully underwent laparoscopic total gastrectomy with D 2 lymph node dissection, without conversion to open surgery or perioperative death. The proximal length between tumor and surgical margin, time of esophagojejunal anastomosis, length of auxiliary incision were (2.3±0.9)cm, (32±3)minutes, (7.5±1.6)cm for the semi-end-to-end anastomosis group, respectively, versus (1.6±1.0)cm, (42±5)minutes, (4.8±1.2)cm for the side-to-side anastomosis group, showing significant differences between the two groups ( t=3.334, 10.177, 8.734, P<0.05). During the esophageal jejunal anastomosis, one patient in the side-to-side anastomosis group had proximal jejunum punctured by a linear cutting stapler resulting in jejunal rupture. The ruptured segment of jejunum was resected and the mesojejunum was freed to perform side-to-side anastomosis. (2) Postoperative situations: there was 1 and 7 patients with postoperative anastomotic bleeding in the semi-end-to-end anastomosis group and side-to-side anastomosis group, respectively, showing a significant difference ( χ2=4.449, P<0.05). Patients with postoperative anastomotic bleeding in the semi-end-to-end anastomosis group and side-to-side anastomosis group were cured after conservative treatment including blood transfusion and endoscopic hemostasis. One patient with esophagojejunal fistula in the side-to-side anastomosis group was cured after conservative treatment including puncture drainage and anti-infective treatment. Two patients with duodenal stump fistula in side-to-side anastomosis group were cured by anti-infection, puncture drainage and nutritional support. Eight patients with pulmonary infection (5 cases in semi-end-to-end anastomosis group and 3 cases in side-to-side anastomosis group) were cured by anti-infection, atomization and expectorant therapy. Three patients with abdominal infection (2 cases in semi-end-to-end anastomosis group and 1 case in side-to-side anastomosis group) were cured by anti-infection and abdominal puncture drainage. One case with incisional infection in semi-end-to-end anastomosis group was cured by dressing change and anti-infective treatment. (3) Follow-up: all the 85 patients were followed up for 1 year. During the follow-up, 3 and 2 patients died in semi-end-to-end anastomosis group and side-to-side anastomosis group, 0 and 2 patients had anastomotic stricture. There was no anastomotic recurrence. Conclusion:In laparoscopic total gastrectomy of adenocarcinoma of esophagogastric junction, semi-end-to-end esophagojejunal anastomosis has the advantages of higher proximal surgical magin from the tumor, shorter anastomosis time, less postoperative anastomotic bleeding, while side-to-side anastomosis anastomosis has shorter length of auxiliary incision.

Objective::To investigate the pharmacodynamics of volatile oil in couplet medicines of Moslae Herba and Pogostemonis Herba, to establish a method for simultaneous determination of three essential ingredients (thymol, carvacrol and patchouli alcohol) in volatile oil of the couplet medicines by gas chromatography (GC), to optimize the preparation process of β-cyclodextrin (β-CD) inclusion complex of volatile oil in the couplet medicines and to confirm the formation of the inclusion complex. Method::An in vitro inflammatory response model was established by hyaluronidase activity inhibition test in order to detect the anti-inflammatory activity of the volatile oil. Also, the antioxidant activity of the volatile oil was assessed by 1, 1-diphenyl-2-trinitrophenylhydrazine (DPPH) free radical scavenging method. The inclusion of volatile oil in couplet medicines of Moslae Herba and Pogostemonis Herba was prepared by scaturated aqueous solution method, colloid milling method and grinding method, respectively. GC was used to determine the contents of thymol, carvacrol and patchouli alcohol in volatile oil for optimizing extraction and inclusion processes of volatile oil. Scanning electron microscope, infrared spectroscopy, thermal differential analysis, and X-ray diffraction (XRD) were used to verify the formation of the inclusion complex. Result::The volatile oil not only inhibited hyaluronidase activity to a certain extent, but also eliminated DPPH and increased with the increase of concentration. There was a good linear relationship between the peak area and concentration of thymol, carvacrol and patchouli alcohol at 0.021 3-0.426, 0.020 04-0.400 8, 0.022 6-0.452 g·L-1 (R2>0.999), respectively. Their recoveries were 99.59%(RSD 1.6%), 100.15%(RSD 1.5%), 100.70%(RSD 1.4%), respectively. The colloid milling method was optimized, and the formation of the inclusion complex was verified by the aforementioned methods. Conclusion::The volatile oil in couplet medicines of Moslae Herba and Pogostemonis Herba has certain anti-inflammatory activity and anti-oxidation ability. The colloid milling method was the best inclusion process for the volatile oil. The established GC has the advantages of simple, sensitive, accurate, reliable and reproducible, which can meet the requirements of simultaneous determination of thymol, carvacrol and patchouli alcohol in the inclusion complex.

OBJECTIVE@#To explore the feasibility and safety of robotic surgical system for radical gastrectomy after liver transplantation.@*METHODS@#A 65-year-old male patient with gastric cancer after liver transplantation underwent radical distal subtotal gastrectomy using Da Vinci surgical system at the General Surgery Department of Southwest Hospital Affiliated to the Army Military Medical University on October 23,2018. The placement of Trocars was arranged using five-hole method. No metastatic tumors were found during intraperitoneal exploration and the first hepatic hilum was found to be wrapped with omentum majus. The tumor located at gastric antrum near the lesser curvature. Then the first and the second station lymph nodes were dissected successively. Distal gastrectomy, Billroth II and Brown anastomosis were performed. The anatomical changes of upper abdomen and gastric lymph reflux after liver transplantation were analyzed.@*RESULTS@#Radical distal gastrectomy with D2 lymphadenectomy was successfully performed under the whole robotic surgical system. The operative time was 315 minutes,and blood loss was 145 ml. A total of 19 lymph nodes were dissected, of which 11 were metastatic lymph nodes. The operative difficulty was to separate the adhesion around the hepatic hilum precisely so as to avoid the damage of hepatic surface, as well as the colon hepatic flexure and duodenum which were closely adhered to hepatic hilum. Meanwhile,it was necessary to pay attention to protetion for the common bile duct and portal vein. The endoscopic wrist joint of the robot surgical system was flexible and delicate, which had obvious advantages in the process of anatomical separation of the adhesions among organs and adhesions around denuded common hepatic artery without normal vascular sheath. Semi-liquid diet was provided on the third day after operation. The immunosuppressants were resumed on the third day after operation. The patient was discharged on the 7th day postoperatively without any complications. There were no abdominal bleeding, incision infection,anastomotic leakage, anastomotic stenosis and other complications. Two months after operation, the patients diet and daily life is normal.@*CONCLUSION@#The robotic surgical system is safe and feasible for gastric cancer surgery after liver transplantation.

Objective@#To investigate the safety and feasibility of laparoscopic operation in thetreatment of gastric gastrointestinal stromal tumor (GIST) at unfavorable positions.@*Methods@#A retrospective cohort study was conducted to analyze the clinical data of patients with gastric GIST at unfavorable positions confirmed by pathology after surgery (laparoscopy or laparotomy) at the Southwest Hospital of the Army Medical University and the Minda Hospital of Hubei Minzu University from June 2008 to June 2018. The unfavorable positions of stomach are defined as the esophagogastric junction, the proximal cardia of gastric lesser curvature, the pylorus of stomach, the posterior wall of stomach and the antrum of stomach.Exclusion criteria:(1) preoperative chemotherapy or imatinib therapy; (2) diameter of tumor > 10 cm; (3) tumor metastasis or concurrence of other malignant tumors. A total of 244 patients (238 in Southwest Hospital and 6 in Minda Hospital) were enrolled, including 122 males and 122 females with age of 41-70years. Operative methods should be adopted according to patients' wishes. There were 146 cases in the laparoscopic surgery group and98 cases in the open surgery group. The intraoperative blood loss, operative time, postoperative first flatus time, postoperative firstfeeding time,average hospital stay, morbidity of postoperative complication,1-,3-,and 5-year recurrence free survival(RFS) and overall survival (OS)rate were compared between the two groups.@*Results@#There were no significant differences in sex, age, tumor size, tumor risk grade or growth pattern between the laparoscopic and the open surgery groups (all P>0.05),and these two groups were comparable. Compared with open group, laparoscopic group had less intraoperative blood loss [(31.4±2.3) ml vs. (143.9±3.7) ml, t=292.800, P<0.001], shorter postoperative first flatus time [(2.1±0.7) days vs.(3.8±0.8) days, t=17.550,P<0.001], shorter postoperative first feeding time [(2.1±0.5) days vs.(2.3±1.7) days, t=1.339,P=0.020], shorter hospital stay [(8.6±2.6) days vs. (13.6±3.2) days, t=13.410, P<0.001], and lower morbidity of postoperative complication [16(11.0%) vs. 21(21.4%),χ2=4.996,P=0.025], whose differences were statistically significant. While the operation time was similar in two groups [(124.7±15.8) minutes vs. (120.9±14.5) minutes, t=1.903,P=0.058]. The median follow-up of all the patients was 43 (1 to 119) months.In laparoscopic group and open group, the 1-, 3- and 5-year RFS were 94.5% vs. 93.9%, 91.1% vs. 90.8%,and 82.2% vs. 81.6%, respectively, and 1-, 3- and 5-year OS were 98.6% vs. 95.9%, 95.9% vs. 94.9%,and 91.1% vs. 88.8%, respectively, whose differences were not statistically significant (all P>0.05).@*Conclusion@#In the experienced gastrointestinal surgery center, laparoscopic resection of gastric GIST at unfavorable position is safe and feasible, achieving the same efficacy of open surgery.

Objective@#To compare the clinical efficacy of proximal gastrectomy with double tract reconstruction (PG-DT) and total gastrectomy with Roux-en-Y reconstruction (TG-RY) for proximal gastric cancer.@*Methods@#The retrospective study was conducted. Clinicopathological data of 132 patients with proximal gastric cancer confirmed by pathology who underwent PG-DT (n=51) or TG-RY (n=81) by the same surgeon team in Southwest Hospital of Army Military Medical University between January 2006 and December 2016 were collected. Patients with preoperative neoadjuvant therapy, non-R0 resection and non-adenocarcinoma confirmed by pathology were excluded. Observation indicators included intraoperative (operation time and blood loss); postoperative (time to flatus, hospital stay, total complications, metastasis of lymph nodes around distal side of stomach from cases undergoing TG-RY), follow-up (long-term hemoglobin level, incidence of anemia, and survival) parameters. Survival analysis was conducted using the Kaplan-Meier method, and Log-rank test was used to compare survival difference between two groups.@*Results@#No statistically significant differences were found between two groups in the baseline data, including age, gender, BMI, hemoglobin level before operation, postoperative TNM stage, tumor size and histological differentiation between two groups (all P>0.05). There were no significant differences between PG-DT and TG-RY in intraoperative blood loss [200 (200) ml vs. 200 (195) ml, Z=-1.860, P=0.063], time to flatus [(2.7±1.0) days vs. (2.6±1.1) days, t=0.225, P=0.823], postoperative hospital stay [10(3) days vs. 10 (4) days, Z=-0.449, P=0.654] and morbidity of perioperative complications [5.9% (3/51) vs. 8.6% (7/81), χ2=0.081, P=0.775]. Compared with the TG-RY group, PG-DT group had longer total operative time [294 (97) minutes vs. 255 (71) minutes, Z=–3.148, P=0.002]. The hemoglobin data of 42 patients with PG-DT and 56 patients with TG-RY were collected 1 year after operation. The incidence of anemia in PG-DT group was lower than that of TG-RY group [64.2%(27/42) vs. 82.1% (46/56), χ2=4.072, P=0.045], and PG-DT group had higher level of hemoglobin than TG-RY group [(114.4±16.3) g/L vs. (106.6±15.0) g/L, t=2.435, P=0.017]. There were 4 cases (4/81, 4.9%) with metastasis of lymph nodes around distal side of stomach in TG-RY group. All of these 4 tumors were T4 in depth and were more than 5 cm in diameter. The median follow-up period was 26 (1 to 110) months. One-year, 3-year and 5-year survival rates were 93.2%, 65.3% and 55.0% in PG-DT group, and 85.8%, 63.8% and 47.2% in TG-RY group, respectively without significant difference (χ2=0.890, P=0.345).@*Conclusions@#Compared with TG-RY, PG-DT has the same safety and feasibility for proximal gastric cancer. Although the operative time is a little longer than TG-RY, PG-DT has advantages in improving the postoperative hemoglobin level.

Objective To analyze the postoperative complications of Da Vinci robotic total gastrectomy for gastric cancer,and explore the risk factors for postoperative complications.Methods The retrospective casecontrol study was conducted.The clinicopathological data of 173 patients with gastric cancer who were admitted to the First Affiliated Hospital of Army Medical University from March 2010 to March 2019 were collected.There were 138 males and 35 females,aged from 34 to 76 years,with an average age of 60 years.All the 173 patients underwent Da Vinci robotic total gastrectomy for gastric cancer.Observation indicators:(1) postoperative complications;(2) analysis of risk factors for postoperative complications of Da Vinci robotic total gastrectomy for gastric cancer.Count data were expressed as absolute numbers or percentages.Univariate analysis was perform7d using the chi-square test or Fisher exact probability.Indicators with P < 0.l were included into multivariate analysis,and multivariate analysis was performed using logistic regression model.Results (1) Postoperative complications:of the 173 patients,45 had postoperative complications,with a incidence rate of 26.0% (45/173).Among the 45 patients,5 had grade Ⅰ postoperative complications,31 had grade Ⅱ postoperative complications,2 had grade Ⅲ a postoperative complications,3 had grade Ⅲ b postoperative complications,1 had grade Ⅳ a postoperative complications,1 had grade Ⅳ b postoperative complications,and 2 had grade Ⅴ postoperative complications.The incidence of serious complications was 5.2% (9/173).Of the 5 patients with grade Ⅰ complications,1 of fever was improved after antipyretic treatment,2 of incisional fat liquefaction were improved after dressing change,1 of vomiting was improved after being given antiemetic,and 1 of delayed recovery of gastrointestinal function was improved after symptomatic treatment.Among 31 patients with grade Ⅱ complications,12 patients had pulmonary infection,including 6 of pulmonary infection alone,3 combined with pleural effusion,1 combined with abdominal infection,2 combined with intestinal obstruction,and all were improved after conservative treatment;7 of fever were improved after anti-infection treatment;4 patients had deep venous catheter infection including 1 combined with bilateral pleural effusion,and were improved after removing catheter and antiinfection treatment;3 patients had anastomotic leakage including 1 with pulmonary infection and abdominal infection,and were improved after conservative treatment;2 patients had duodenal stump leakage (1 combined with pulmonary infection,1 combined with pulmonary infection and pleural effusion),and were improved after conservative treatment;1 patient had abdominal hemorrhage,and was improved after conservative treatment;1 patient had intestinal obstruction,and was improved after conservative treatment;1 patient had abdominal infection,and was improved after conservative treatment.Of the 2 patients with grade Ⅲ a complications,1 had duodenal stump leakage combined with abdominal abscess,and was improved after puncture and drainage;1 had pleural effusion combined with pulmonary infection,and was improved after puncture and drainage.Among the 3 patients with grade Ⅲ b complications,1 of abdominal hemorrhage was improved after reoperation,2 of anastomotic leakage were improved after being placed jejunal nutrition tube under painless gastroscopy.Of the 2 cases,1 combined with abdominal infection and 1 combined with pleural effusion and abdominal infection were improved after puncture and drainage.Among the 2 patients with grade Ⅳ complications,1 of Ⅳa encountering respiratory failure was improved after treatment due to misinhalation of anesthesia,and 1 of Ⅳb suffered from multiple organ failure and was improved after treatment due to anastomotic leakage.Two patients with grade Ⅴ complication died,including one with anastomotic leakage,abdominal hemorrhage,and multiple organ failure,and the other with respiratory failure and cardiac insufficiency.In the 173 patients,the incidence of comprehensive complication index (CCI) ≥ 25.2 was 11.0% (19/173).(2) Analysis of risk factors for postoperative complications of Da Vinci robotic total gastrectomy for gastric cancer:univariate analysis showed that body mass index (BMI),volume of intraoperative blood loss,and operation time were the related factors affecting the postoperative complications (x2=4.275,5.057,5.463,P< 0.05).BMI and volume of intraoper.ative blood loss were the related factors affecting the postoperative serious complications (x2 =7.517,5.537,P < 0.05).Age,BMI and Charlson Comorbidity Index were the related factors affecting CCI ≥ 25.2 (.x2 =8.946,7.890,4.062,P< 0.05).Multivariate analysis showed that tumor diameter ≥ 3 cm and tumor located at esophagogastric junction were independent risk factors for postoperative complications [odds ratio (OR) =4.350,2.175,95% confidence interval (CI):1.352-14.000,1.018-4.647,P<0.05)].BMI ≥25 kg/m2 was an independent risk factor for serious complications after operation (OR=5.156,95%CI:1.120-23.738,P<0.05).Age ≥60 years,BMI ≥ 25 kg/m2,and history of abdominal surgery were independent risk factors for CCI ≥25.2 (OR =30.928,3.557,6.009,95%CI:1.485-644.19,1.082-11.691,1.358-26.592,P<0.05).Conclusions The Clavien-Dindo classification of patients after Da Vinci robotic total gastrectomy for gastric cancer is mostly grade IⅡ.The main complications are pulmonary-related complications.CCI can better predict the risk factors for serious complications after operation.Tumor diameter ≥ 3 cm and tumor located at esophagogastric junction are independent risk factors for postoperative complications;BMI ≥ 25 kg/m2 is an independent risk factor for serious complications;age ≥ 60 years,BMI ≥25 kg/m2,and history of abdominal surgery are independent risk factors for CCI≥25.2.
