Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

389
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...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

608
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube...

Inflammatory Bowel Disease V: Surgical Management

346
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:

Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

938
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors01:19

Oral Hypoglycemic Agents: α-Glucosidase Inhibitors

445
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.
Acarbose and miglitol are...

Summary

Preoperative carbohydrate loading in patients undergoing surgery improved outcomes by reducing complications and enhancing patient satisfaction. This approach did not negatively impact perioperative glycemia, offering a beneficial strategy for surgical recovery.

Area of Science:

  • Anesthesiology
  • Surgical Nutrition
  • Perioperative Medicine

Background:

  • Conventional fasting protocols are standard before surgery.
  • The impact of preoperative oral carbohydrate loading on surgical outcomes requires further investigation.

Purpose of the Study:

  • To evaluate the effect of preoperative oral carbohydrate loading on the perioperative period.

Main Methods:

  • 93 patients undergoing elective abdominal/retroperitoneal surgery were studied.
  • The main group (n=47) received a carbohydrate-protein drink preoperatively.
  • The control group (n=46) followed the American Society of Anesthesiologists (ASA) fasting guidelines.

Main Results:

  • No significant differences in perioperative glycemia were observed between groups.
  • The carbohydrate loading group showed reduced intraoperative infusion volumes and more stable hemodynamics.
  • Fewer patients in the carbohydrate group experienced organ dysfunction, complications, postoperative nausea/vomiting, and general weakness.

Conclusions:

  • Preoperative carbohydrate loading is safe, not affecting perioperative glycemia.
  • It leads to reduced intraoperative fluid requirements and improved hemodynamic stability.
  • This nutritional strategy enhances patient comfort and satisfaction post-surgery.
