Summary
Self-expandable metal stents are safe and effective for elderly patients with malignant colorectal stenosis (MCS). Prophylactic stenting in asymptomatic elderly patients with MCS is a viable option, showing comparable outcomes to palliative stenting.
Area of Science:
- Gastroenterology
- Oncology
- Geriatrics
Background:
- Malignant colorectal stenosis (MCS) commonly affects the elderly.
- Self-expandable metal stents (SEMS) are a palliative treatment for MCS.
- Prophylactic SEMS placement in asymptomatic elderly patients is not well-established.
Purpose of the Study:
- To evaluate the efficacy and safety of SEMS in elderly patients with MCS in a palliative setting.
- To compare outcomes between palliative stenting and palliative stoma.
- To assess the safety and efficacy of prophylactic SEMS in asymptomatic elderly patients with MCS.
Main Methods:
- Retrospective study of elderly patients with MCS from April 2017 to June 2022.
- Comparison of palliative stenting group (n=31) versus palliative stoma group (n=12).
- Subgroup analysis of asymptomatic patients receiving prophylactic stenting within the stent group.
Main Results:
- Overall survival and complication rates were similar between stent and stoma groups.
- Patients receiving stents had a significantly shorter hospital stay.
- Prophylactic stenting in 16 asymptomatic patients did not increase complication rates.
Conclusions:
- Palliative SEMS are effective and safe for elderly patients with MCS.
- Prophylactic stenting can be considered for asymptomatic elderly patients with MCS.
- SEMS offer a favorable option for managing malignant colorectal stenosis in the elderly.

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

146
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

122
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.

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
