RESUMEN
BACKGROUND: The population of elderly patients with gastric cancer is increasing, which is a major public health issue in China. Malnutrition is one of the greatest risk factors for adverse clinical outcomes in elderly patients with gastric cancer. AIM: To investigate the preoperative nutritional status and its association with delayed discharge of elderly gastric cancer patients following radical gastrectomy. METHODS: A total of 783 patients aged 65 years and older harboring gastric adenocarcinoma and following radical gastrectomy were retrospectively analyzed from the prospectively collected database of Zhongshan Hospital of Fudan University between January 2018 and May 2020. RESULTS: The overall rate of malnutrition was 31.8%. The incidence of postoperative complications was significantly higher in the malnourished group compared to the well-nourished group (P < 0.001). Nutritional characteristics in the malnourished group, including body mass index, prognostic nutritional index (PNI), albumin, prealbumin, and hemoglobin, were all significantly lower than those in the well-nourished group. The percentage of patients who received postoperative total nutrient admixture was lower in the malnourished group compared to the well-nourished group (22.1% vs 33.5%, P = 0.001). Age ≥ 70 years (HR = 1.216, 95%CI: 1.048-1.411), PNI < 44.5 (HR = 1.792, 95%CI: 1.058-3.032), operation time ≥ 160 minutes (HR = 1.431, 95%CI: 1.237-1.656), and postoperative complications grade III or higher (HR = 2.191, 95%CI: 1.604-2.991) were all recognized as independent risk factors associated with delayed discharge. CONCLUSION: Malnutrition is relatively common in elderly patients undergoing gastrectomy. Low PNI is an independent risk factor associated with delay discharge. More strategies are needed to improve the clinical outcome of these patients.
RESUMEN
Background: To investigate the predictive value of preoperative peripheral blood inflammatory markers for surgical site infection (SSI) in laparoscopic radical gastrectomy for gastric cancer. Methods: A retrospective analysis was conducted on patients undergoing laparoscopic radical gastrectomy for gastric cancer, categorized into SSI and non-SSI groups based on postoperative SSI occurrences. Patient demographics, surgical details, laboratory results, and SSI incidence data were extracted. Differences in indicators, including neutrophil-lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and platelet-lymphocyte ratio (PLR), were assessed between the two groups. Multivariate logistic regression was utilized to determine the independent association of each indicator with SSI. Receiver operating characteristics (ROC) curve analysis was utilized to evaluate the predictive value of parameters. Results: Of 169 patients, 36 (21.30%) experienced SSI postoperatively. The SSI group exhibited higher preoperative NLR and SII (p < 0.05). After adjusting for variables, preoperative NLR (OR = 1.691, 95% CI: 1.211-2.417, p = 0.003) and SII (OR = 1.001, 95% CI: 1.000-1.002, p = 0.006) were identified as independent risk factors for SSI. Both NLR (AUC = 0.758, 95% CI: 0.666-0.850) and SII (AUC = 0.753, 95% CI: 0.660-0.850) demonstrated favorable diagnostic performance for predicting postoperative SSI. Conclusion: Preoperative NLR and SII significantly associate with postoperative SSI in laparoscopic radical gastrectomy for gastric cancer, making them valuable indicators for early prediction of SSI.
RESUMEN
BACKGROUND: Laparoscopic-assisted radical gastrectomy (LARG) is the standard treatment for early-stage gastric carcinoma (GC). However, the negative impact of this procedure on respiratory function requires the optimized intraoperative management of patients in terms of ventilation. AIM: To investigate the influence of pressure-controlled ventilation volume-guaranteed (PCV-VG) and volume-controlled ventilation (VCV) on blood gas analysis and pulmonary ventilation in patients undergoing LARG for GC based on the lung ultrasound score (LUS). METHODS: The study included 103 patients with GC undergoing LARG from May 2020 to May 2023, with 52 cases undergoing PCV-VG (research group) and 51 cases undergoing VCV (control group). LUS were recorded at the time of entering the operating room (T0), 20 minutes after anesthesia with endotracheal intubation (T1), 30 minutes after artificial pneumoperitoneum (PP) establishment (T2), and 15 minutes after endotracheal tube removal (T5). For blood gas analysis, arterial partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2) were observed. Peak airway pressure (Ppeak), plateau pressure (Pplat), mean airway pressure (Pmean), and dynamic pulmonary compliance (Cdyn) were recorded at T1 and T2, 1 hour after PP establishment (T3), and at the end of the operation (T4). Postoperative pulmonary complications (PPCs) were recorded. Pre- and postoperative serum interleukin (IL)-1ß, IL-6, and tumor necrosis factor-α (TNF-α) were measured by enzyme-linked immunosorbent assay. RESULTS: Compared with those at T0, the whole, anterior, lateral, posterior, upper, lower, left, and right lung LUS of the research group were significantly reduced at T1, T2, and T5; in the control group, the LUS of the whole and partial lung regions (posterior, lower, and right lung) decreased significantly at T2, while at T5, the LUS of the whole and some regions (lateral, lower, and left lung) increased significantly. In comparison with the control group, the whole and regional LUS of the research group were reduced at T1, T2, and T5, with an increase in PaO2, decrease in PaCO2, reduction in Ppeak at T1 to T4, increase in Pmean and Cdyn, and decrease in Pplat at T4, all significant. The research group showed a significantly lower incidence of PPCs than the control group within 3 days postoperatively. Postoperative IL-1ß, IL-6, and TNF-α significantly increased in both groups, with even higher levels in the control group. CONCLUSION: LUS can indicate intraoperative non-uniformity and postural changes in pulmonary ventilation under PCV-VG and VCV. Under the lung protective ventilation strategy, the PCV-VG mode more significantly improved intraoperative lung ventilation in patients undergoing LARG for GC and reduced lung injury-related cytokine production, thereby alleviating lung injury.
RESUMEN
Objective: This study aimed to evaluate the efficacy and safety of buccal acupuncture on postoperative analgesia, perioperative stress response and adverse events in elderly patients undergoing laparoscopic radical gastrectomy. Methods: It was a prospective, outcome assessor-blinded, randomized controlled trial, involving 90 patients aged 65-80 years who were treated with an elective laparoscopic radical gastrectomy. They were randomly assigned to buccal acupuncture group (Group B) and control group (Group C). Buccal acupuncture was applied to patients of Group B before the induction of general anesthesia, while no additional application was given to those in Group C. Patient-controlled intravenous analgesia (PCIA) with sufentanil was postoperatively performed in both groups. Sufentanil consumption and the Visual Analog Scale (VAS) score within 48 h postoperatively were assessed as primary outcomes. Secondary outcomes included peripheral levels of stress markers, intraoperative consumptions of anesthetic drugs and postoperative recovery. Results: Patients in Group B presented significantly lower VAS scores within 24 h and less consumption of sufentanil within 48 h postoperatively (both p < 0.01). The awaking time, time to extubation and length of stay were significantly shorter in Group B than in Group C (p = 0.005, 0.001 and 0.028, respectively). Compared with Group C, stress response and inflammatory response within 24 h postoperatively were also significantly milder in Group B. Conclusion: The use of buccal acupuncture before general anesthesia induction favors the postoperative analgesic effect and recovery in elderly patients undergoing laparoscopic radical gastrectomy, the mechanism of which involves relieving postoperative stress response and inflammatory response. Clinical trial registration: This study was registered in the Chinese Clinical Trial Registry (www.chictr.org.cn) on 15/06/2023 (ChiCTR2300072500).
RESUMEN
BACKGROUND: Radical laparoscopic gastrectomy is an important treatment modality for gastric cancer. Surgery requires general anesthesia, and patients are susceptible to the effects of anesthetic drugs and carbon dioxide insufflation during the procedure, leading to inflammation or severe pain, which can affect patient outcome. AIM: To explore the efficacy of combining dexmedetomidine (DEX) with nalbuphine in patients underwent laparoscopic radical gastrectomy for gastric cancer. METHODS: Patients scheduled to undergo laparoscopic radical gastrectomy were selected and randomly assigned to A or B group. In A group, patients received an intravenous injection of nalbuphine 0.2 mg/kg + DEX 0.4 µg/kg 10 min before the end of surgery; in B group, patients received only an intravenous injection of nalbuphine. The trends in hemodynamic parameter fluctuations, awakening quality during the recovery period, serum inflammatory markers, agitation scores, cough severity, incidence, and duration of postoperative delirium (POD) were compared. RESULTS: The mean arterial pressure and heart rate in the A group were more stable (P < 0.05). The A group had a lower average awakening time, extubation time, and agitation scores during recovery than the B group. Agitation control in the A group was more effective at different time points (P < 0.05). Patients in the A group had lower serum interleukin (IL)-6, tumour necrosis factor alpha, and IL-10 levels at 1 h after surgery than the B group. The incidence of coughing and duration of POD were lower and shorter in the A group than in the B group. Adverse reactions caused by the two anesthesia methods were less frequent in the A group than in the B group (P < 0.05). CONCLUSION: The use of DEX and nalbuphine in patients undergoing laparoscopic radical gastrectomy for gastric cancer help reducing the inflammatory response, cough severity, and agitation and helps maintain hemodynamic stability.
RESUMEN
Background: Duodenal stump fistula represents an infrequent but serious complication after laparoscopic radical gastrectomy with Billroth II or Roux-en-Y reconstruction for gastric cancer. The present study was designed to evaluate the effectiveness of laparoscopic double half purse-string sutures plus "8" pattern of stitching for reinforcement of duodenal stump. Methods: The data of patients undergoing laparoscopic radical gastrectomy with Billroth II or Roux-en-Y reconstruction were retrospectively analyzed between August 2022 and June 2023. According to the different reinforcement methods of duodenal stump, included patients were subdivided into three groups as follows: Group A, duodenal stump was treated with double half purse-string sutures plus "8" pattern of stitching; Group B, duodenal stump was reinforced by continuous suture using a barbed suture; and Group C, duodenal stump without any additional processing. The incidences of duodenal stump fistula between three groups were documented and compared. Moreover, the independent risk factors associated with duodenal stump fistula were analyzed using the logistic regression analysis. Results: No postoperative duodenal stump fistula occurred in Group A, which was significantly different from Group B and Group C (P = .007). In the multivariate analysis, age (odds ratio [OR], 1.191; 95% confidence interval [CI], 1.088-1.303), body mass index (OR, 0.824; 95% CI, 0.727-0.935), and American Society of Anesthesiologists score (OR, 4.495; 95% CI, 1.264-15.992) were the risk factors for duodenal stump fistula. Conclusion: Double half purse-string sutures plus "8" pattern of suture can be conducted in a relatively short operation period and could prevent the incidence of duodenal stump fistula to some extent.
RESUMEN
OBJECTIVE: In patients undergoing laparoscopic radical gastrectomy, the use of subcostal transversus abdominis plane block (STAPB) for completely opioid-free postoperative pain management lacks convincing clinical evidence. METHODS: This study included 112 patients who underwent laparoscopic radical gastrectomy at the 900TH Hospital of the Joint Logistics Support Force from October 2020 to March 2022. Patients were randomly divided into (1:1) continuous opioid-free STAPB (C-STAPB) group and conventional group. In the C-STAPB group, 0.2% ropivacaine (bilateral, 20 ml per side) was injected intermittently every 12 h through a catheter placed on the transverse abdominis plane for postoperative pain management. The conventional group was treated with a conventional intravenous opioid pump (2.5 µg/kg sufentanil and 10 mg tropisetron, diluted to 100 ml with 0.9% NS). The primary outcomes were the accumulative area under the curve of the numeric rating scale (NRS) score at 24 and 48 h postoperatively at rest and during movement. The secondary outcomes were postoperative recovery outcomes, postoperative daily food intake, and postoperative complications. RESULTS: After exclusion (n = 16), a total of 96 patients (C-STAPB group, n = 46; conventional group, n = 49) were included. We found there were no significant differences in the cumulative AUC of NRS score PACU-24 h and PACU-48 h between the C-STAPB group and conventional group at rest [(mean difference, 1.38; 95% CI, - 2.21 to 4.98, P = 0.447), (mean difference, 1.22; 95% CI, - 6.20 to 8.65, P = 0.744)] and at movement [(mean difference, 2.90; 95% CI, - 3.65 to 9.46; P = 0.382), (mean difference, 4.32; 95% CI, - 4.46 to 13.1; P = 0.331)]. The 95% CI upper bound of the difference between rest and movement in the C-STAPB group was less than the inferior margin value (9.5 and 14 points), indicating the non-inferiority of the analgesic effect of C-STPAB. The C-STAPB group had faster postoperative recovery profiles including earlier bowel movement, defecation, more volume of food intake postoperative, and lower postoperative nausea and vomiting compared to conventional groups (P < 0.001). CONCLUSIONS: After laparoscopic radical gastrectomy, the analgesic effect of C-STAPBP is not inferior to the traditional opioid-based pain management model. TRIAL REGISTRATION: ChiCTR2100051784.

BACKGROUND: Preoperative sarcopenia is associated with prognosis in patients with gastric cancer (GC); however, studies with 10-year survival follow-up are lacking. METHODS: Consecutive patients with GC who underwent radical gastrectomy between December 2009-2012 were included retrospectively. Preoperative sarcopenia was diagnosed using computed tomography skeletal muscle index. The Kaplan-Meier method estimated overall survival (OS) and relapse-free survival (RFS). Cox proportional hazard regression analysis determined the prognostic factors for OS and RFS. RESULTS: In total, 781 patients with GC were included; among these, 207 (26.5%) had preoperative sarcopenia. Patients with sarcopenia had significantly lower 10-year OS and RFS than patients without sarcopenia (39.61% vs. 58.71% and 39.61% vs. 57.84%, respectively). Further, preoperative sarcopenia was an independent risk factor for 10-year OS (HR = 1.467; 95% confidence interval [CI]: 1.169-1.839) and RFS (HR = 1.450; 95% CI: 1.157-1.819). Patients with sarcopenia had a higher risk of death and recurrence in the first 10 years postoperatively than patients without sarcopenia. Additionally, the risk of death (HR = 2.62; 95% CI:1.581-4.332) and recurrence (HR = 2.34; 95% CI:1.516-3.606) was the highest in the 1st postoperative year and remained relatively stable thereafter. Further, postoperative adjuvant chemotherapy significantly improved 10-year OS (p = 0.006; HR = 0.558) and RFS (p = 0.008; HR = 0.573) in patients with TNM stage II-III GC that presented with sarcopenia. CONCLUSION: Preoperative sarcopenia remained an independent risk factor for postoperative very long-term prognosis of GC. Postoperative adjuvant chemotherapy improved the long-term outcomes of stage II-III patients with sarcopenia.

BACKGROUND: Laparoscopic radical gastrectomy is widely used, and perioperative complications have become a highly concerned issue. AIM: To develop a predictive model for complications in laparoscopic radical gastrectomy for gastric cancer to better predict the likelihood of complications in gastric cancer patients within 30 days after surgery, guide perioperative treatment strategies for gastric cancer patients, and prevent serious complications. METHODS: In total, 998 patients who underwent laparoscopic radical gastrectomy for gastric cancer at 16 Chinese medical centers were included in the training group for the complication model, and 398 patients were included in the validation group. The clinicopathological data and 30-d postoperative complications of gastric cancer patients were collected. Three machine learning methods, lasso regression, random forest, and artificial neural networks, were used to construct postoperative complication prediction models for laparoscopic distal gastrectomy and laparoscopic total gastrectomy, and their prediction efficacy and accuracy were evaluated. RESULTS: The constructed complication model, particularly the random forest model, could better predict serious complications in gastric cancer patients undergoing laparoscopic radical gastrectomy. It exhibited stable performance in external validation and is worthy of further promotion in more centers. CONCLUSION: Using the risk factors identified in multicenter datasets, highly sensitive risk prediction models for complications following laparoscopic radical gastrectomy were established. We hope to facilitate the diagnosis and treatment of preoperative and postoperative decision-making by using these models.

Objective To explore the effect of ropivacaine combined with dexmedetomidine in transversus abdominis plane block(TAPB)on postoperative stress hormones and cognitive function in patients undergoing laparoscopic radical gastrectomy.Methods A total of 80 patients undergoing laparoscopic radical gastrectomy at the First Affiliated Hospital of Xinxiang Medical University from April to October 2023 were selected as the research subjects.According to different anesthesia methods,the patients were divided into the observation group and the control group,with 40 patients in each group.Patients in the observation group were injected bilaterally with 2.5 g·L-1 ropivacaine and 0.5 μg·kg-1 dexmedetomidine for TAPB,with 20 mL injection on each side.Patients in the control group were injected bilaterally with 2.5 g·L-1 ropivacaine for TAPB,with 20 mL injection on each side.Mean arterial pressure(MAP)and heart rate(HR)were recorded at the time of admission to the operating room(T1),immediately after endotracheal intubation(T2),40 minutes after pneumoperitoneum(T3),and 15 minutes after extubation(T4).Radioimmunoprecipitation was used to detect serum cortisol(COR)level,and enzyme-linked immunosorbent assay was used to measure serum norepinephrine(NE)and epinephrine(E)levels at 1,6,12,and 24 hours after surgery.Visual analog scale(VAS)was used to assess pain at rest,and Ramsay sedation scale(RSS)was used to evaluate sedation depth.The doses of propofol and sufentanil were compared between the two groups.Serum β-amyloid(Aβ)and S100β protein levels at 1 day before surgery,1 and 3 days after surgery were detected by using the enzyme-linked immunosorbent assay,and cognitive function was assessed at the same time points by using the mini-mental state examination(MMSE).Results At T,and T2,there was no significant difference in MAP and HR between the control group and the observation group(P>0.05).At T3 and T4,MAP and HR in the observation group were significantly lower than those in the control group(P<0.05).At 1,6,and 12 hours postoperatively,VAS score in the observation group was significantly lower than that in the control group(P<0.05).At 24 hours postoperatively,there was no significant difference in VAS score between the control group and observation group(P>0.05).At 1 and 6 hours postoperatively,RSS score in the observation group was significantly higher than that in the control group(P<0.05).At 12 and 24 hours postoperatively,there was no significant difference in RSS score between the control group and observation group(P>0.05).At 1,6,and 12 hours postoperatively,COR,NE,and E levels in the observation group were significantly lower than those in the control group(P<0.05).At 24 hours postoperatively,there was no significant difference in COR,NE,and E levels between the control group and observation group(P>0.05).The doses of propofol and sufentanil in the observation group were significantly lower than those in the control group(P<0.05).One day before surgery,there was no significant difference in MMSE score between the control group and observation group(P>0.05).At 1 and 3 days postoperatively,MMSE score in the observation group was significantly higher than that in the control group(P<0.05).One day before surgery,there was no significant difference in serum Aβ and S100β protein levels between the control group and observation group(P>0.05).At 1 and 3 days postoperatively,serum Aβ and S100β protein levels in the observation group were significantly lower than those in the control group(P<0.05).Conclusion Ropivacaine combined with dexmedetomidine in TAPB in radical gastrectomy can significantly reduce postoperative pain,increase sedative effect,prolong the duration of TAPB,and benefit patients'postoperative recovery with reduced cognitive impairment.
RESUMEN
Objective To investigate the expression levels and prognostic value of preoperative serum exosomes micro RNA(miR)-193a and micro RNA(miR)-208b in patients with gastric cancer(GC).Methods A total of 132 patients who underwent GC radical gastrectomy in the First Affiliated Hospital of Xinjiang Medical University from March 2018 to March 2020 were regarded as the GC group,while 132 healthy individuals who underwent physical examination were selected as the control group.Their clinical and pathological data were collected and compared.The relative expression levels of miR-193a and miR-208b in serum exosomes were detected using quantitative real-time polymerase chain reaction(qRT-PCR)method.Pearson method was used to analyze the correlation between miR-193a and miR-208b.The correlation between the expression of miR-193a and miR-208b in preoperative serum exosomes of GC patients and postoperative prognosis was analyzed using Kaplan-Meier method.Univariate and multivariate COX regression were applied to analyze the influencing factors of prognosis.Results The expression level of miR-208b in the serum exosomes of the GC group was higher than that of the control group(1.77±0.14 vs 1.02±0.01),while the expression level of miR-193a was lower than that of the control group(0.52±0.06 vs 1.01±0.01),and the differences were statistically significant(t=92.551,61.392,all P<0.05).The expression levels of miR-193a and miR-208b in GC patients before surgery were negatively correlated(r=-0.409,P<0.05).The low expression rate of miR-193a and high expression rate of miR-208b in patients with TNM stage Ⅰ+Ⅱ,no lymph node metastasis,and no distant metastasis were lower than those in patients with TNM stage Ⅲ+Ⅳ,lymph node metastasis,and distant metastasis,and the differences were statistically significant(χ2=5.008,4.397;7.142,4.688;4.407,5.189,all P<0.05).The 3-year cumulative survival rate of patients with low expression of miR-193a(30.43%)was lower than that of patients with high expression(60.32%)(χ2=17.861,P<0.001),while the 3-year cumulative survival rate of patients with high expression of miR-208b(27.14%)was lower than that of patients with low expression(64.52%)(χ2=16.340,P<0.001).The independent prognostic factors included serum levels of exosomes miR-193a(HR=0.493,95%CI:0.323~0.753)and miR-208b(HR=2.697,95%CI:1.382~5.262)(all P<0.05).Conclusion The preoperative serum miR-193a level in the exosomes was decreased and miR-208b level was increased,and their expression levels were related to the prognosis of patients undergoing GC radical gastrectomy.
RESUMEN
Objective:To investigate the effect of the explain-simulate-practice-communication-support (ESPCS) nursing model on perioperative stress and postoperative rehabilitation in patients undergoing laparoscopic radical gastrectomy for gastric cancer. Provide a basis for the application of ESPCS nursing model in patients undergoing radical gastrectomy for gastric cancer.Methods:This was a quasi-experimental study. A total of 212 patients who underwent laparoscopic radical gastrectomy for gastric cancer in the First Affiliated Hospital of China Medical University from May 2019 to May 2023 were selected by convenience sampling and divided into the observation group and the control group by random digital table method, with 106 patients in each group. The control group received routine nursing intervention, while the observation group received ESPCS nursing intervention for 3 months. The perioperative stress hormones (serum cortisol and epinephrine), Self-rating Depression Scale (SDS) score, Self-rating Anxiety Scale (SAS) score, gastrointestinal function indicators, and the 36-item Short Form Health Survey Questionnaire (SF-36) score were compared between the two groups.Results:Two groups of patients were lost to follow-up, with a total of 104 patients in each group. The control group consisted of 65 males and 39 females, aged (61.59 ± 3.42) years old, while the observation group consisted of 61 males and 43 females, aged (60.78 ± 3.63) years old. Six days after operation, serum cortisol and epinephrine levels in the observation group were (221.46 ± 24.15) nmol/L and (28.11 ± 3.47) pmol/L, respectively, which were lower than those in the control group (261.84 ± 27.91) nmol/L and (31.49 ± 3.86) pmol/L, respectively, and the differences were statistically significant ( t=11.16, 6.64, both P<0.05). After 1 week of operation, the SDS and SAS scores in the observation group were (41.39 ± 2.21), (39.62 ± 2.31) points, respectively, which were lower than those in the control group (45.27 ± 2.34), (44.35 ± 2.37) points, and the differences were statistically significant ( t=12.29, 14.58, both P<0.05). The time of first exhaust, first defecation, intestinal ringing and first solid eating in the observation group were (55.38 ± 6.23), (68.84 ± 7.92), (38.73 ± 4.31), (62.31 ± 7.67) h, respectively, which were lower than those in the control group (67.51 ± 8.39), (84.17 ± 9.25), (48.43 ± 5.79), (75.65 ± 8.52) h, the differences were statistically significant ( t values were 11.84-13.71, all P<0.05). After intervention, the scores of physiological function, role physical, general health, mental health, social function and the total score of SF-36 in the observation group were (82.17 ± 4.12), (83.21 ± 3.67), (75.27 ± 3.64), (80.63 ± 4.31), (77.58 ± 4.13), (73.89 ± 4.86) points, respectively, which were higher than those in the control group (75.61 ± 4.39), (74.24 ± 3.88), (69.45 ± 4.38), (71.28 ± 4.05), (72.35 ± 3.84), (68.81 ± 5.14) points, the differences were statistically significant ( t values were 7.32-17.13, all P<0.05). Conclusions:The ESPCS nursing model can effectively alleviate the perioperative stress reaction of gastric cancer patients undergoing laparoscopic radical gastrectomy, promote the recovery of gastrointestinal function and improve the quality of life.
RESUMEN
BACKGROUND: This retrospective study aimed to assess the suitability of POSSUM and its modified versions, E-PASS and its modified score, SRS, and SORT scores for predicting postoperative complications and mortality in patients undergoing laparoscopic radical gastrectomy for gastric cancer. MATERIALS AND METHODS: Data analysis was performed on 349 patients who underwent laparoscopic radical gastrectomy at Tianjin Medical University General Hospital between January 2016 and December 2021. The discriminative ability of the scoring systems was evaluated using the area under the receiver operating characteristic curve (AUC). The primary endpoint focused on the prediction of postoperative complications, while the secondary endpoint assessed the prediction of postoperative mortality. RESULTS: Among the scoring systems evaluated, the modified E-PASS (mE-PASS) score exhibited the highest AUC (0.846) and demonstrated the highest sensitivity (81%) and specificity (79%) for predicting postoperative complications. All other scores, except for POSSUM, showed moderate discriminative ability in predicting complications. In terms of predicting postoperative mortality, the E-PASS score had the highest AUC (0.978), while the mE-PASS score displayed the highest sensitivity (76%) and specificity (90%). Notably, both E-PASS and mE-PASS scores exhibited excellent discriminative ability. CONCLUSIONS: The P-POSSUM, O-POSSUM, E-PASS, mE-PASS, SRS, and SORT scoring systems are useful tools for predicting postoperative outcomes in laparoscopic radical gastrectomy. Among them, the mE-PASS score demonstrated the best predictive power. However, the POSSUM system could only be applicable to predict postoperative mortality.

BACKGROUND: Postoperative complications are important factors affecting the survival time and quality of life of patients undergoing radical gastrectomy. AIM: To investigate and compare the anesthetic effects of intravenous general anesthesia combined with epidural anesthesia or ultrasound-guided bilateral transversus abdominal plane block (TAPB) in gastric cancer patients undergoing laparoscopic radical gastrectomy. METHODS: The clinical data of 85 patients who underwent laparoscopic radical gastrectomy in our hospital from December 2020 to January 2023 were retrospectively collected and divided into a TAPB group (n = 45) and epidural anesthesia group (n = 40) according to the different anesthesia and analgesia programs used. The TAPB group received general anesthesia combined with TAPB, and the epidural anesthesia group received general anesthesia combined with epidural anesthesia. The pain status, cognitive status, intestinal barrier indicators, recovery quality, and incidence of complications were compared between the two groups. RESULTS: Compared with the epidural anesthesia group, the TAPB group's visual analog scale scores were significantly lower 6 h, 12 h, 24 h and 48 h after surgery (P < 0.05). The incidence of postoperative cognitive dysfunction (POCD) in the TAPB group was significantly lower than that in the epidural anesthesia group, and the Mini-mental State Examination score 24 h after surgery was significantly higher in the TAPB group than the epidural anesthesia group (P < 0.05). The levels of diamine oxidase and plasma D-lactate were significantly lower in the TAPB group than the epidural anesthesia group 24 h after surgery (P < 0.05). The agitation score and the incidence of agitation during recovery were significantly lower in the TAPB group than epidural anesthesia group (P < 0.05). The total incidence of postoperative complications in the TAPB group was 4.44%, significantly lower than the 20.00% in the epidural anesthesia group (P < 0.05). CONCLUSION: Compared with epidural anesthesia combined with general anesthesia, TAPB combined with general anesthesia had a good analgesic effect in laparoscopic radical gastrectomy and can further reduce the incidence of POCD and postoperative complications, improve the levels of intestinal barrier indicators, and improve postoperative recovery quality.
RESUMEN
BACKGROUND: Esophageal gastric anastomosis is a common surgical technique used to treat patients with gastric cancer who undergo total gastrectomy. However, using simple anastomosis techniques alone may not meet the needs of patients in some cases and can lead to complications such as anastomotic stenosis and ulceration. In order to overcome these issues and improve patient prognosis, muscle flap reconstruction technique has emerged. Muscle flap reconstruction is a method of improving gastric-esophageal anastomosis by transplanting muscle tissue. By covering the anastomotic site with muscle tissue, it not only enhances the stability of the anastomosis site but also increases blood supply, promoting healing and recovery of the anastomosis. Therefore, the use of muscle flap reconstruction technique in esophageal gastric anastomosis during total gastrectomy for gastric cancer is increasingly widely applied. AIM: To determine the effectiveness of esophagogastric anastomosis using the muscle flap reconstruction technology in total abdominal gastrectomy for gastric cancer and perform follow-up experiments to understand the factors affecting patients' prognosis. METHODS: The study subjects were 60 patients with gastric cancer who were admitted to our hospital between October 2018 and January 2022. All patients underwent esophagogastric anastomosis using the double muscle flap reconstruction technology in total abdominal gastrectomy. Perioperative indicators were determined, and patients were followed up for 1 year. Furthermore, patient outcomes were observed within 1 year, followed by patient classification based on different outcomes. Moreover, clinicopathological parameters were observed and relevant factors affecting patient prognosis were analyzed. RESULTS: The operation time was 318 ± 43 min, the formation time of esophageal double muscle flap anastomosis was 110 ± 13 min, the number of lymph node dissections was 26 ± 6, the incision length was 3 ± 0.6 cm, intraoperative bleeding volume was 48 ± 15 mL, first anal exhaust time was 5.3 ± 1.8 d, first meal time was 6.0 ± 1.6 d, length of hospital stay was 11.8 ± 2.5, and treatment cost was 5.8 ± 0.7 thousand yuan. The patient experienced three postoperative complications: 2 cases of pulmonary infection and 1 case of respiratory discomfort. During 1-year follow-up, 50 patients survived and 10 died. Univariate analysis revealed that histological types, tumor size, tumor-node-metastasis staging, vascular invasion, and postoperative adjuvant radiotherapy and chemotherapy were the main factors affecting the prognosis of surviving patients. Furthermore, Cox regression analysis revealed that postoperative adjuvant radiotherapy and chemotherapy were the main factors affecting patient prognosis. The survival time of the survival group was significantly higher than that of the death group (P < 0.05). CONCLUSION: Esophagogastric anastomotic using muscle flap reconstruction exhibits good effects on patients who undergo total abdominal gastrectomy for cancer. Postoperative adjuvant radiotherapy and chemotherapy are the main factors affecting patient prognosis.
RESUMEN
Duodenal stump fistula (DSF) is a serious complication of radical gastrectomy for gastric cancer. Herein, we illustrated an innovative choice for treating duodenal stump fistulas by placing a modified sump drainage through trocar puncture into the DSF-related abscess (DSF-abscess) cavity. We retrospectively analyzed 974 consecutive patients who underwent gastrectomy for gastric cancer between 2011 and 2021. Of these patients, 34 who developed postoperative duodenal stump fistulas postoperatively were enrolled into our study, and their clinical data were retrospectively assessed. From January 2011 to December 2017, 15 patients received conventional treatments (percutaneous catheter drainage, PCD group) known as the traditional percutaneous method, and 19 patients from January 2018 to December 2021 received new treatments (Troca's SD group) consisting of conventional therapies and placement of a modified sump drainage through trocar puncture into DSF-abscess cavity. The demographics, clinical characteristics and treatment outcomes were compared between two groups. Compared with the PCD group, the rates of postoperative complications, duodenostomy creation, subsequent surgery, fistula healing rates of the DSF, and length of postoperative hospital stay were significantly decreased in the Troca SD group. However, there was no significant difference in the abscess recurrence rate and mortality rates. Trocar puncture with a modified sump drainage is an safe, effective, and technically feasible treatment for duodenal stump fistula after radical gastrectomy for gastric cancer. This novel technique should be further investigated using large-scale RCT research.
RESUMEN
OBJECTIVE: This study aimed to analyze the risk factors for the occurrence of postoperative hyperactive delirium after laparoscopic radical gastrectomy under general anesthesia in patients with gastric cancer. METHODS: The clinical data of 280 gastric cancer patients who underwent laparoscopic radical gastrectomy under general anesthesia in First Affiliated Hospital of Gannan Medical University from January 2020 to June 2023 were retrospectively analyzed, and the types and incidence of postoperative delirium were recorded. The factors influencing the occurrence of postoperative hyperactive delirium were analyzed. RESULTS: Multi-factor logistic regression analysis showed that older age, high dosage of anesthetic drug consumption, high American Society of Anesthesiologists (ASA) classification (or ASA grade 3-4), long Post-anesthesia Care Unit (PACU) stay, and long extubation time were independent risk factors for the occurrence of hyperactive delirium after laparoscopic radical gastrectomy (OR > 1, P < 0.05). The area under the curve of the nomogram was used to predict the occurrence of hyperactive delirium after laparoscopic radical gastrectomy under general anesthesia was 0.903 (95% CI: 0.846-0.978). CONCLUSION: Older age, high dosage of anesthetic drug consumption, high ASA classification (or ASA grade 3-4), long PACU stay, and long extubation time were independent risk factors affecting the occurrence of hyperactive delirium after laparoscopic radical gastrectomy under general anesthesia.
RESUMEN
OBJECTIVE: To investigate short-term efficacy of direct laparoscopic-assisted radical gastrectomy (LAG) versus non-curative endoscopic submucosal dissection (ESD) plus additional LAG for early gastric cancer. MATERIALS AND METHODS: 286 patients were retrospectively assigned into two groups: direct LAG group (n = 255) and additional LAG (ESD plus LAG, n = 31) group. A 1:2 propensity score matching was performed to equalize relevant confounding factors between two groups for analysis. RESULTS: Ninety-three patients were successfully matched, including 62 in the direct LAG group and 31 in the additional LAG group. A significant (P = 0.013) difference existed in the drainage removal time between the additional LAG and direct LAG group (7 d vs. 6 d). Age, sex, tumor location and surgical approach were significantly (P < 0.05) associated with complications, with age ≥ 60 years (P = 0.002) and total gastrectomy (P = 0.011) as significant independent risk factors. A significant (P = 0.023) difference existed in the surgical time between the early and late groups (193.3 ± 37.6 min vs. 165.5 ± 25.1 min). CONCLUSION: Additional LAG (D1 + lymphadenectomy) after ESD may be safe and effective even though non-curative ESD may prolong the drainage removal time and increase the difficulty of surgery.
