Association Between Subtotal Gastrectomy with Billroth II Anastomosis and Coronary Heart Disease

Clinical Efficacy of Laparoscopic Billroth II Subtotal Gastrectomy Plus Lienal Polypeptide Injection for Gastric Cancer

Objective

To evaluate the clinical efficacy of laparoscopic Billroth II subtotal gastrectomy plus lienal polypeptide injection for gastric cancer.

Methods

Between May 2018 and January 2021, 110 patients with gastric cancer treated in Jingzhou First People's Hospital were recruited and assigned via the random number table method to either an observation group or a control group, with 55 patients in each group. All patients received laparoscopic Billroth II subtotal gastrectomy, and the observation group additionally received lienal polypeptide injection. Outcome measures include surgical indexes, clinical efficacy, and adverse events.

Results

The patients in the observation group had significantly less intraoperative hemorrhage volume, smaller surgical wounds, shorter time lapse before passing gas and hospital stay, and longer operation time than those in the control group (P < 0.001). The observation group showed significantly higher efficacy than the control group (P=0.001). The observation group had a significantly lower incidence of toxic side effects and adverse events than the control group (P < 0.05). After treatment, the CD3+ and CD4+ levels were significantly elevated and the CD8+ level was decreased, with higher CD3+ and CD4+ levels and lower CD8+ levels in the observation group than in the control group (P < 0.05).

Conclusion

In the treatment of patients with gastric cancer, laparoscopic Billroth II subtotal gastrectomy plus lienal polypeptide injection features promising efficacy, improves the immune function of patients, effectively reduces the occurrence of toxic side effects and adverse reactions, with less trauma and rapid recovery, which shows good potential for use in clinical application.

The effect of cholecystectomy on the risk of acute myocardial infarction in patients with gallbladder stones

Objectives: To investigate the effect of cholecystectomy on the subsequent risk of acute myocardial infarction (AMI) in patients with gallbladder stones (GBS).Methods: We used the Taiwan National Health Insurance Research Database (NHIRD) for hospitalization to conduct a retrospective nationwide population-based cohort study. The study cohort consisted of a total of 122,421 patients aged ≥20 years with cholecystectomy for GBS between 2000 and 2010. The control cohort consisted of the GBS patients without cholecystectomy and they were randomly selected by propensity score matching with the study cohort at a 1:1 ratio according to age, sex, occupation category, urbanization level, comorbidities, and year of the index date for cholecystectomy. We measured the incidence of AMI for both cohorts.Results: The cumulative incidence of AMI was lower in GB patients with cholecystectomy than that in those without cholecystectomy (2.26 vs 3.28 per 1000 person-years, adjusted hazard ratio [aHR] = 0.65, 95% confidence interval [CI] = 0.61-0.69). Compared to those without cholecystectomy, the risk of developing AMI after cholecystectomy was 0.69 (95% CI = 0.63-0.76) for the first year, 0.69 (95% CI = 0.63-0.77) for 2-5 years, and 0.59 (95% CI = 0.53-0.66) for ≥5 years, respectively.Conclusions: Our findings indicate cholecystectomy ameliorates the risk of AMI in patients with GBS, and the protective effect tends to increase with incremental duration of follow-up. However, it needs more studies to ascertain the protective mechanisms of cholecystectomy against AMI.

The Effect of Cholecystectomy on the Risk of Colorectal Cancer in Patients with Gallbladder Stones

To evaluate the risk of colorectal cancer (CRC) after cholecystectomy for gallbladder stones (GBS).

METHODS

This nationwide population-based cohort study analyzed the inpatient data from the Taiwan National Health Insurance Research Database. The study cohort comprised of 83,963 patients aged 20 years undergoing cholecystectomy for GBS between 2000 and 2010. The control cohort comprised the GBS patients without cholecystectomy, who were propensity matched with the study cohort at a 1:1 ratio based on age, sex, comorbidities, and the index date for cholecystectomy.

RESULTS

The cumulative incidence of CRC within 6 months of follow-up was higher in the cholecystectomy cohort than that in the non-cholecystectomy cohort (aHR (adjusted hazard ratio) = 7.90, 95% confidence interval (CI) = 6.27-9.94; log-rank test, p < 0.001). The cumulative incidence of CRC after 6 months of follow-up was lower in the cholecystectomy cohort than that in the non-cholecystectomy cohort (aHR = 0.66, 95% CI = 0.60-0.73; log-rank test, p < 0.001), but the reduced risk of CRC for the cholecystectomy cohort was statistically significant only in rectal cancer after separately considering females (aHR = 0.64, 95% CI = 0.46-0.88) and males (aHR = 0.59, 95% CI = 0.44-0.79).

CONCLUSIONS

The positive association between cholecystectomy and the CRC risk within the first 6 months after cholecystectomy might be due to a detection bias or pre-existing CRC. However, cholecystectomy is associated with a decreased risk of rectal cancer, rather than proximal or distal colon cancer, after more than 6 months of follow-up.

A Retrospective Administrative Database Analysis of Suicide Attempts and Completed Suicide in Patients With Chronic Pancreatitis

Background: The actual incidence rate of suicide attempt and the suicide-related fatality rate (completed suicide) in patients with chronic pancreatitis (CP) have not been mentioned in the literature. Methods: We conducted a nationwide population-based cohort study by analyzing data from Taiwan's National Health Insurance Research Database (NHIRD) to compare the rate of suicide attempt between a CP cohort and a non-CP cohort. For the study cohort, we identified 17,733 patients (age ≥ 20 years) diagnosed as having CP between 2000 and 2010 from the NHIRD in Taiwan. Beneficiaries with no history of CP were matched with the study cohort at a 2:1 ratio according to age, sex, and index date. To determine the incidence of suicide, all patients were followed until the end of 2011 or until their withdrawal from the Taiwan National Health Insurance program. Results: Patients with CP had an increased risk of suicide attempt, compared with those without CP (adjusted hazard ratio [aHR] = 2.72, 95% confidence interval [CI] = 1.69-4.37). The suicide-related fatality in the CP cohort was higher than that in the non-CP cohort, but the difference was not statistically significant (aHR = 1.21, 95% CI = 0.39-3.78). Conclusion: Our population-based cohort study reveals a close association between CP and subsequent suicide attempt. Compared with the non-CP cohort, the suicide-related fatality was higher in the CP cohort, although the result was not statistically significant. These findings necessitate surveying patients with CP and providing psychological support to prevent suicide.
