Bariatric Surgery (Weight loss surgery):
Biliopancreatic Deviation
General description
Biliopancreatic diversion is a malabsorsive bariatric surgery procedure in which nutrient absorption decreases because the passage of biliar and pancreatic secretions is altered. There could also be “duodenal change”.
Weight loss surgery patients must be aware of pre and post surgery requirements.
Benefits
Bariatric surgery of this type is designed for patients who have a body mass index (BMI) of 50 kg/m2 and higher. The recommended age range is between 14 and 65. Nevertheless, there can be exceptions to this rule.
Biliopancreatic diversion offers the following advantages:
• This type of surgery is advisable for patients with extreme obesity
• Weight loss is over 90% of excess. Nevertheless, the majority of patients suffer from frequent diarrhea
Disadvantages include:
• Frequent diarrhea
• Flatulence
• Some cases of malnutrition
Potential complications involved are:
• Trans and post surgery bleeding
• Anastomotic "leakage"
• Internal hernia
• Intestinal obstruction
• Pulmonary embolus
• Obesity-related respiratory distress syndrome
• Death
Technical description
Procedure – Biliopancreatic diversion reduces the size of the stomach, but not as much as compared to bypass surgery. The small intestine is cut and put back together in such a way that food and secretions unite in a common one-meter handle before reaching the colon. Sometimes poor nutrient intake can result and, in turn, causes diarrhea and flatulence in some patients.
Hospitalization – Biliopancreatic diversion requires a four night stay in the hospital.
Time – Between two and a half and four and a half hours.
