Inflammatory Bowel Disease V: Surgical Management01:21

Inflammatory Bowel Disease V: Surgical Management

909
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.
Here are some common surgical interventions for IBD:

Drugs for Treatment of Ulcerative Colitis in IBD01:29

Drugs for Treatment of Ulcerative Colitis in IBD

698
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Endoscopic Procedures II: Colonoscopy

1.3K
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.0K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents

744
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

1.2K
Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Summary

Endoscopic therapies offer less invasive management for colorectal polyps and superficial cancers. While potentially curative in select cases, data is limited, necessitating careful patient selection due to recurrence risks.

Area of Science:

  • Gastroenterology and Endoscopy
  • Surgical Oncology
  • Colorectal Cancer Management

Background:

  • Endoscopic techniques are increasingly utilized for colorectal polyps and superficial cancers.
  • These methods offer a less morbid alternative to radical resection in select patients.
  • Curative potential exists, but data supporting local and ablative therapies for colorectal cancer is limited.

Purpose of the Study:

  • To review local and ablative therapies for colorectal neoplasia.
  • To outline indications and successful circumstances for these endoscopic techniques.

Main Methods:

  • Literature review of endoscopic management of colorectal polyps and superficial cancers.
  • Analysis of data supporting local and ablative therapies.
  • Identification of criteria for successful application in select cases.

Main Results:

  • Endoscopic techniques can be palliative or curative in carefully selected patients.
  • Lower morbidity compared to radical resection is a key advantage.
  • Higher local recurrence rates are reported, underscoring the need for careful selection.

Conclusions:

  • Local and ablative endoscopic therapies are viable options for specific colorectal neoplasias.
  • Curative intent requires highly selective patient and lesion criteria.
  • Further research is needed to solidify evidence for these techniques in cancer treatment.
