Venous Thrombosis III: Interprofessional Care

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Esophageal Varices-II: Clinical Features and Management

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Summary

This summary is machine-generated.

Electrocoagulation by diathermy for liver metastases shows uncertain benefits. While combinations with allopurinol or dimethyl sulphoxide may slightly reduce mortality, evidence is limited and of very low certainty.

Area of Science:

Oncology
Surgical Oncology
Hepatobiliary Surgery

Background:

Liver metastases, particularly from colorectal carcinoma, are common and often fatal.
Electrocoagulation by diathermy is a thermal ablation technique for destroying tumour tissue.
Its efficacy and safety for liver metastases remain unclear.

Purpose of the Study:

To assess the benefits and harms of electrocoagulation by diathermy for liver metastases.
To compare it against no intervention, other ablation methods, or systemic treatments.

Main Methods:

A systematic review of randomised trials was conducted.
Searches included multiple databases up to October 2020.
One trial with 306 participants was included, assessing electrocoagulation alone or with adjuncts versus a control.

Main Results:

The single included trial had a high risk of bias.
Electrocoagulation alone showed no significant difference in mortality versus control (very low certainty evidence).
Combinations with allopurinol or dimethyl sulphoxide showed a potential mortality reduction (low certainty evidence).
Data on adverse events and other outcomes were largely missing or poorly reported.

Conclusions:

Evidence on electrocoagulation for liver metastases is insufficient due to limited, low-certainty data.
Uncertainty exists regarding its effect on all-cause and post-operative mortality.
Lack of recent trials may be due to the technique's declining use.
