Effect of single-incision laparoscopic distal gastrectomy guided by ERAS and the influence on immune function

Comparative analysis of conventional laparoscopic surgery and single-incision laparoscopic surgery in gastric cancer treatment: Outcomes and prognosis

BACKGROUND

Gastric cancer surgery has advanced with minimally invasive techniques. This study compares outcomes between single-incision laparoscopic surgery plus one port (SILS + 1) and conventional laparoscopic surgery (CLS) in treating gastric cancer.

AIM

To explore the curative effect of SILS + 1 and CLS on gastric cancer and their influences on prognosis.

METHODS

A total of 93 patients with gastric cancer undergoing radical gastrectomy in the hospital were retrospectively analyzed between September 2019 and September 2022. According to different surgical methods, they were divided into SILS + 1 group (n = 56) and CLS group (n = 37). The perioperative indexes, pain degree [visual analogue scale (VAS)] and stress response [C-reactive protein (CRP), white blood cell count (WBC)] in the two groups were compared. The postoperative complications, recurrence rate and mortality at 1 year after surgery were recorded.

RESULTS

Intraoperative blood loss was significantly lower in the SILS + 1 group (76.53 ± 8.12 mL) compared to the CLS group (108.67 ± 12.34 mL, P < 0.001), and the total incision length was also significantly shorter in the SILS + 1 group (5.29 ± 1.01 cm vs 9.45 ± 2.34 cm, P < 0.001). SILS + 1 patients experienced faster recovery, with shorter times to first flatus (1.94 ± 0.43 days vs 3.23 ± 0.88 days, P < 0.001) and ambulation (2.76 ± 0.58 days vs 4.10 ± 0.97 days, P < 0.001). Postoperative pain, as measured by VAS scores, was significantly lower in the SILS + 1 group on postoperative days 1, 2, and 3 (P < 0.001). Additionally, stress markers (CRP and WBC) were significantly lower in the SILS + 1 group on the first postoperative day (CRP: 6.41 ± 1.63 mg/L vs 7.82 ± 1.88 mg/L, P < 0.001; WBC: 6.34 ± 1.50 × 109/L vs 7.09 ± 1.61 × 109/L, P = 0.024). The complication rate in the SILS + 1 group was also significantly lower than in the CLS group (8.93% vs 27.03%, P = 0.020). However, there was no significant difference in recurrence rates between the two groups after one year (3.57% vs 8.11%, P > 0.05).

CONCLUSION

SILS + 1 and CLS have the comparable lymph node clearance effect in patients with gastric cancer. However, SILS + 1 is more beneficial to reduce intraoperative blood loss, relieve pain, alleviate stress response, reduce the incidence of complications and promote rapid postoperative recovery.

Enhanced recovery after surgery-based nursing in older patients with postoperative intestinal obstruction after gastric cancer surgery: A retrospective study

BACKGROUND

Gastric cancer-related morbidity and mortality rates are high in China. Patients who have undergone gastric cancer surgery should receive six cycles of chemotherapy according to their condition. During this period, intestinal obstruction is likely to occur. Electrolyte balance disorders, peritonitis, intestinal necrosis, and even hypovolemic shock and septic shock can seriously affect the physical and mental recovery of patients and threaten their health and quality of life (QoL).

AIM

To quantitatively explore the effects of enhanced recovery after surgery (ERAS)–based nursing on anxiety, depression, and QoL of elderly patients with postoperative intestinal obstruction after gastric cancer.

METHODS

The clinical data of 129 older patients with intestinal obstruction after gastric cancer surgery who were treated and cared for in our hospital between January 2019 and December 2021 were examined retrospectively. Nine patients dropped out because of transfer, relocation, or death. According to the order of admissions, the patients were categorized into either a comparison group or an observation group according to the random number table, with 60 cases in each group.

RESULTS

After nursing care, the observation group required significantly less time to eat for the first time, recover bowel sounds, pass gas, and defecate than the comparison group (P < 0.05). No significant difference was noted in nutrition-related indicators between the two groups before care. Before care, the Symptom Check List-90 scores between the two groups were comparable, whereas anxiety, depression, paranoia, fear, hostility, obsession, somatization, interpersonal sensitivity, and psychotic scores were significantly lower in the observation group after care (P < 0.05). The QoL scores between the two groups before care did not differ significantly. After care, the physical, social, physiological, and emotional function scores; mental health score; vitality score; and general health score were significantly higher in the observation group, whereas the somatic pain score was significantly lower in the observation group (P < 0.05).

CONCLUSION

ERAS-based nursing combined with conventional nursing interventions can effectively improve patient’s QoL, negative emotions, and nutritional status; accelerate the time to first ventilation; and promote intestinal function recovery in elderly patients with postoperative intestinal obstruction after gastric cancer surgery.

Short- and long-term outcomes of single-port versus multiport laparoscopic radical gastrectomy for gastric cancer: a meta-analysis of propensity score-matched studies and randomized controlled trials

BACKGROUND

At present, there is no convincing evidence-based medical basis for the efficacy of single-port laparoscopic gastrectomy. To make a high-quality comparison of the short- and long-term outcomes of single-port laparoscopic gastrectomy versus multiport laparoscopic gastrectomy, we performed this meta-analysis, which only included propensity score-matched studies and randomized controlled trials comparing single-port laparoscopic gastrectomy with multiport laparoscopic gastrectomy for patients with gastric cancer.

METHODS

Data were retrieved from the electronic databases PubMed, EMBASE, Medline, Cochrane Library, CNKI, Wanfang and VIP up to January 2023, and the data included the outcomes of treatment after single-port laparoscopic gastrectomy and multiport laparoscopic gastrectomy. The primary outcomes were early complications, survival rate after surgery at 1 year, and survival rate after surgery at 5 years. The secondary outcomes were number of pain medications, mean operation time, estimated blood loss, hospital mortality, time to first soft fluid diet, time to first flatus, hospital stay after surgery, and retrieved number of lymph nodes. The Jadad score and Newcastle‒Ottawa scale were used to assess the quality of the included studies.

RESULTS

After screening, 9 studies were finally included, including 988 patients. The meta-analysis results showed that estimated blood loss (MD=-29.35, 95% CI: -42.95-15.75, P < 0.0001), hospital stay (MD=-0.99, 95% CI:-1.82~-0.17, P = 0.02), and number of pain medications(MD=-0.65, 95% CI:-1.07~-0.23, P = 0.002) in the single-port laparoscopic gastrectomy group were better than those in the multiport laparoscopic gastrectomy group. There is no significant difference between the single-port laparoscopic gastrectomy group and the multiport laparoscopic gastrectomy group in mean operation time(MD = 5.23,95% CI:-16.58~27.04,P = 0.64), time to first soft fluid diet(MD=-0.06,95% CI: -0.30~0.18,P = 0.63), time to first flatus(MD=-0.18,95% CI:-0.43~0.07,P = 0.16), early complication(OR = 0.73,95% CI:0.50~1.09,P = 0.12), hospital mortality(OR = 1.00,95% CI:0.09~11.16,P = 1.00), retrieved number of lymph nodes(MD=-1.15, 95% CI:-2.71~0.40, P = 0.15), survival rate after surgery 1 year(OR = 2.14,95% CI:0.50~9.07,P = 0.30), and survival rate after surgery 5 year(93.7 vs. 87.6%; p = 0.689).

CONCLUSION

This meta-analysis showed that single-port laparoscopic gastrectomy is both safe and feasible for laparoscopic radical gastrectomy for gastric cancer, with similar operation times and better short-term outcomes than multiport laparoscopic gastrectomy in terms of hospital stay, postoperative pain, and estimated blood loss. There was no significant difference in long-term outcomes between single-port laparoscopic gastrectomy and multiport laparoscopic gastrectomy.

Clostridium butyricum potentially improves inflammation and immunity through alteration of the microbiota and metabolism of gastric cancer patients after gastrectomy

Background

Gastrectomy is the most effective treatment to improve the clinical survival rate of patients with gastric cancer. However, the pathophysiological changes caused by gastrectomy have seriously affected the postoperative recovery.

Methods

In the present trial, Ataining (containing C. butyricum, CGMCC0313.1) was applied in patients after gastrectomy to investigate the effect of C. butyricum on the early postoperative recovery by monitoring the inflammatory immune response with blood indicators, detecting the gut microbiota with high-throughput sequencing, and analyzing the short-chain fatty acids (SCFAs) with targeted metabolomics. This study is registered with the number ChiCTR2000040915.

Results

Our outcomes revealed that C. butyricum had significantly reduced the number of Leucocyte (P < 0.001), the percentage of Neutrophil (P < 0.001), the expression of IL-1β (P < 0.01), IL-6 (P < 0.05), and TNF-α (P < 0.01), while markedly enhanced the immunity indexes (immunoglobulin and lymphocyte) (P < 0.05) and nutrition indexes (albumin and total protein) (P < 0.05). In addition, the use of the C. butyricum greatly enriched the relative abundance of beneficial bacteria Bacteroides, Faecalibacterium and Gemmiger, while the abundance of pathogenic Streptococcus, Desulfovibrio and Actinomyces were markedly decreased at genus level. We also observed significant up-regulation of SCFAs, including acetic acid, propionic acid, butyric acid and isobutyric acid, after C. butyricum administration in patients receiving gastrectomy.

Conclusion

Therefore, evidence supported that oral administration of C. butyricum after gastrectomy can reduce early postoperative inflammation, enhance immune ability, restore intestinal microbiota eubiosis, increase intestinal SCFAs, reduce the occurrence of postoperative complications, and ultimately promote the early recovery of the patient.

Effect of Ultrasound Image-Guided Nerve Block on the Postoperative Recovery Quality of Patients with Tibial Fractures Using the Concept of Enhanced Recovery after Surgery

This study was aimed at investigating the clinical effect of ultrasound-guided nerve block based on the concept of enhanced recovery after surgery (ERAS) for postoperative anesthesia in patients with tibial fractures. The noise-reduction processing was introduced in ultrasound images to adjust the ultrasound clarity of the patient. A total of 177 patients with tibial fractures in our hospital were retrospectively analyzed and divided into OG group (general anesthesia combined with nerve block, 78 cases), C1 group (simple general anesthesia, 27 cases), C2 group (ultrasound-guided nerve block combined with general anesthesia, 10 cases), and C3 group (62 cases of spinal-epidural anesthesia). The effect of anesthesia and postoperative recovery time of patients in each group were analyzed. The wake-up time of the OG group was significantly shorter than that of the other three groups (P < 0.05). The doses of propofol and remifentanil in the OG group were much lower than those in the other groups (P < 0.05). After the ultrasound image was processed with noise reduction, the image showed the lesion more clearly. The excellent and good rates of OG group, C1 group, C2 group, and C3 group were 89.86%, 62.73%, 75.37%, and 61.07%, respectively. The Ramsay sedation score and anesthesia satisfaction in the OG group were obviously higher than those in the other groups, but there was no significant difference (P > 0.05). The visual analogue scale (VAS) scores of the OG group at 12 h, 24 h, and 36 h after the surgery were 4.52 ± 0.41, 4.72 ± 0.24, and 4.81 ± 0.74, respectively, which were significantly higher than those of the other three groups (P < 0.05). On the basis of ERAS, ultrasound-guided nerve block combined with general anesthesia can improve the perioperative pain in patients with tibial fractures and significantly shorten the time for the wake-up time. In addition, it was safe and reliable, so it was worthy of clinical promotion.

Correlation analysis between preoperative systemic immune inflammation index and prognosis of patients after radical gastric cancer surgery: based on propensity score matching method

BACKGROUND

To explore the correlation between the preoperative systemic immune inflammation index (SII) and the prognosis of patients with gastric carcinoma (GC).

METHODS

The clinical data of 771 GC patients surgically treated in the Department of Gastrointestinal Surgery, Qinghai University Affiliated Hospital from June 2010 to June 2015 were retrospectively analyzed, and their preoperative SII was calculated. The optimal cut-off value of preoperative SII was determined using the receiver operating characteristic (ROC) curve, the confounding factors between the two groups were eliminated using the propensity score matching (PSM) method, and the correlation between preoperative SII and clinicopathological characteristics was assessed by chi-square test. Moreover, the overall survival was calculated using Kaplan-Meier method, the survival curve was plotted, and log-rank test was performed for the significance analysis between the curves. Univariate and multivariate analyses were also conducted using the Cox proportional hazards model.

RESULTS

It was determined by the ROC curve that the optimal cut-off value of preoperative SII was 489.52, based on which 771 GC patients were divided into high SII (H-SII) group and low SII (L-SII) group, followed by PSM in the two groups. The results of Kaplan-Meier analysis showed that before and after PSM, the postoperative 1-, 3-, and 5-year survival rates in L-SII group were superior to those in H-SII group, and the overall survival rate had a statistically significant difference between the two groups (P < 0.05). Before PSM, preoperative SII [hazard ratio (HR) = 2.707, 95% confidence interval (CI) 2.074-3.533, P < 0.001] was an independent risk factor for the prognosis of GC patients. After 1:1 PSM, preoperative SII (HR = 2.669, 95%CI 1.881-3.788, P < 0.001) was still an independent risk factor for the prognosis of GC patients.

CONCLUSIONS

Preoperative SII is an independent risk factor for the prognosis of GC patients. The increase in preoperative SII in peripheral blood indicates a worse prognosis.
