Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

99
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...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

15
Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Area of Science:

  • Surgical Oncology
  • Gastrointestinal Surgery
  • Vascular Surgery

Background:

  • Presacral venous bleeding (PSVB) presents a significant challenge during rectal mobilization surgery.
  • Existing methods for managing PSVB have limitations, necessitating novel approaches.
  • Effective control of PSVB is crucial for patient safety and surgical outcomes.

Purpose of the Study:

  • To introduce and evaluate an effective surgical technique for managing presacral venous bleeding (PSVB).
  • To demonstrate the efficacy of Professor Xiaogang Bi's purse-string suture method for PSVB control.

Main Methods:

  • A novel purse-string suture technique was employed, with stitches penetrating the sacral periosteum around the bleeding site.
  • Tightening the suture compressed presacral venous plexus branches against the sacrum, occluding blood flow.
  • The technique was applied to ten patients experiencing PSVB between April 2017 and November 2022.

Main Results:

  • Bi's suture effectively controlled PSVB in all ten patients.
  • Immediate control was achieved in nine cases solely with the purse-string suture.
  • One case required supplementary bone wax and pelvic gauze packing for complete hemostasis.

Conclusions:

  • Bi's purse-string suture is a highly effective and easily performable method for managing presacral venous bleeding.
  • This technique does not require specialized materials, making it broadly applicable.
  • The study confirms the clinical utility of Bi's suture in controlling intractable PSVB during rectal surgery.
