Critical values of monitoring indexes for perioperative major adverse cardiac events in elderly patients with biliary diseases

BACKGROUND

Major adverse cardiac events (MACE) in elderly patients with biliary diseases are the main cause of perioperative accidental death, but no widely recognized quantitative monitoring index of perioperative cardiac function so far.

AIM

To investigate the critical values of monitoring indexes for perioperative MACE in elderly patients with biliary diseases.

METHODS

The clinical data of 208 elderly patients with biliary diseases in our hospital from May 2016 to April 2021 were retrospectively analysed. According to whether MACE occurred during the perioperative period, they were divided into the MACE group and the non-MACE group.

RESULTS

In the MACE compared with the non-MACE group, postoperative complications, mortality, hospital stay, high sensitivity troponin-I (Hs-TnI), creatine kinase isoenzyme (CK-MB), myoglobin (MYO), B-type natriuretic peptide (BNP), and D-dimer (D-D) levels were significantly increased (P < 0.05). Multivariate logistic regression showed that postoperative BNP and D-D were independent risk factors for perioperative MACE, and their cut-off values in the receiver operating characteristic (ROC) curve were 382.65 pg/mL and 0.965 mg/L, respectively.

CONCLUSION

The postoperative BNP and D-D were independent risk factors for perioperative MACE, with the critical values of 382.65 pg/mL and 0.965 mg/L respectively. Consequently, timely monitoring and effective maintenance of perioperative cardiac function stability are of great clinical significance to further improve the perioperative safety of elderly patients with biliary diseases.

Therapeutic experience of an 89-year-old high-risk patient with incarcerated cholecystolithiasis: A case report and literature review

BACKGROUND

The global pandemic of coronavirus disease 2019 pneumonia poses a particular challenge to the emergency surgical treatment of elderly patients with high-risk acute abdominal diseases. Elderly patients are a high-risk group for surgical treatment. If the incarceration of gallstones cannot be relieved, emergency surgery is unavoidable.

CASE SUMMARY

We report an 89-year-old male patient with acute gangrenous cholecystitis and septic shock induced by incarcerated cholecystolithiasis. He had several coexisting, high-risk underlying diseases, had a history of radical gastrectomy for gastric cancer, and was taking aspirin before the operation. Nevertheless, he underwent emergency laparoscopic cholecystectomy, with maintenance of postoperative heart and lung function, successfully recovered, and was discharged on day 8 after the operation.

CONCLUSION

Emergency surgery for elderly patients with acute abdominal disease is safe and feasible during the coronavirus disease 2019 pandemic, the key is to abide strictly by the hospital’s epidemic prevention regulations, fully implement the epidemic prevention procedure for emergency surgery, fully prepare before the operation, accurately perform the operation, and carefully manage the patient postoperatively.

Strategies for diagnosis and treatment of benign and malignant colorectal obstruction

Colorectal obstruction is one of the most common acute abdominal diseases in surgery department. Because of complex etiological factors, severe condition, and rapid progression, timely diagnosis and proper treatment are necessary for colorectal obstruction. By searching the literature and based on our experience in clinical practice, we performed a comprehensive and systematic analysis of the etiology, diagnosis and treatment of benign and malignant colorectal obstruction, and summarize the main points of diagnosis and treatment of benign and malignant colorectal obstruction as follows: identifying the etiology of benign and malignant colorectal obstruction; flexible application of colonography with meglumine diatrizoate, CT virtual endoscopy, and colonoscopy; preoperative colonoscopic drainage as a bridge to surgery; strict control of surgical indication; precise surgical procedures; and active symptomatic treatment. These measures are of important significance in improving the diagnosis and treatment of benign and malignant colorectal obstruction.

Ischemic or toxic injury: A challenging diagnosis and treatment of drug-induced stenosis of the sigmoid colon

A 48-year-old woman was admitted with 15-mo history of abdominal pain, diarrhea and hematochezia, and 5-mo history of defecation difficulty. She had been successively admitted to nine hospitals, with an initial diagnosis of inflammatory bowel disease with stenotic sigmoid colon. Findings from computed tomography virtual colonoscopy, radiography with meglumine diatrizoate, endoscopic balloon dilatation, metallic stent implantation and later overall colonoscopy, coupled with the newfound knowledge of compound Qingdai pill-taking, led to a subsequent diagnosis of ischemic or toxic bowel disease with sigmoid colon stenosis. The patient was successfully treated by laparoscopic sigmoid colectomy, and postoperative pathological examination revealed ischemic or toxic injury of the sigmoid colon, providing a final diagnosis of drug-induced sigmoid colon stenosis. This case highlights that adequate awareness of drug-induced colon stenosis has a decisive role in avoiding misdiagnosis and mistreatment. The diagnostic and therapeutic experiences learnt from this case suggest that endoscopic balloon expansion and colonic metallic stent implantation as bridge treatments were demonstrated as crucial for the differential diagnosis of benign colonic stenosis. Skillful surgical technique and appropriate perioperative management helped to ensure the safety of our patient in subsequent surgery after long-term use of glucocorticoids.

Therapeutic experience of 289 elderly patients with biliary diseases

AIM

To present clinical characteristics, diagnosis and treatment strategies in elderly patients with biliary diseases.

METHODS

A total of 289 elderly patients with biliary diseases were enrolled in this study. The clinical data relating to these patients were collected in our hospital from June 2013 to May 2016. Patient age, disease type, coexisting diseases, laboratory examinations, surgical methods, postoperative complications and therapeutic outcomes were analyzed.

RESULTS

The average age of the 289 patients with biliary diseases was 73.9 ± 8.5 years (range, 60-102 years). One hundred and thirty-one patients (45.3%) had one of 10 different biliary diseases, such as gallbladder stones, common bile duct stones, and cholangiocarcinoma. The remaining patients (54.7%) had two types of biliary diseases. One hundred and seventy-nine patients underwent 9 different surgical treatments, including pancreaticoduodenectomy, radical resection of hilar cholangiocarcinoma and laparoscopic cholecystectomy. Ten postoperative complications occurred with an incidence of 39.3% (68/173), and hypopotassemia showed the highest incidence (33.8%, 23/68). One hundred and sixteen patients underwent non-surgical treatments, including anti-infection, symptomatic and supportive treatments. The cure rate was 97.1% (168/173) in the surgical group and 87.1% (101/116) in the non-surgical group. The difference between these two groups was statistically significant (χ² = 17.227, P < 0.05).

CONCLUSION

Active treatment of coexisting diseases, management of indications and surgical opportunities, appropriate selection of surgical procedures, improvements in perioperative therapy, and timely management of postoperative complications are key factors in enhancing therapeutic efficacy in elderly patients with biliary diseases.

Blood lead dynamics of lead-exposed pregnant women and its effects on fetus development

The dynamics of blood lead (Pb-B) and blood zinc protoporphyrin (ZPP-B) of women in early pregnancy and parturient women with lead exposure and the effects on fetus development were investigated. Pb-B of lead-exposed women was high: 0.984 mumol/L (20.38 micrograms/dl) and ZPP was 84.52 micrograms/dl. Cord blood Pb-B was 0.896 mumol/L (18.56 micrograms/dl) and cord blood ZPP was 69.24 micrograms/dl. In the control group, Pb-B was 0.261 mumol/L (5.41 micrograms/dl), ZPP-B, 37.59 micrograms/dl, cord blood, Pb-B 0.34 mumol/L (7.03 micrograms/dl), and cord ZPP-B 49.0 micrograms/dl. There was a significant correlation between blood lead and blood ZPP, maternal Pb-B and cord Pb-B, maternal Pb-B and cord ZPP-B. The significance of the consistency of high level Pb-B and the effects on fetus development is discussed.

[Lead placental transfer and metals content in biosamples from occupationally lead exposed female workers]

This paper presents a study of five metals content in biosamples of placenta, maternal venous blood, cord blood from 32 occupationally lead exposed female workers and 32 controls. The results showed that lead levels in biosamples of lead exposed individuals were significantly greater than those from controls. Results also showed that there existed very close relationships between placental lead and maternal blood lead, placental lead and cord blood lead, maternal blood lead and cord blood lead, showing that there was a lead transfer from the mother to the child via the placenta. The relationships between metals in the biosamples were also discussed in the paper.
