Blind loop syndrome is a medical condition that occurs when the intestine is obstructed, slowing or stopping the progress of digested food, and thus facilitating the growth of bacteria to the point that problems in nutrient absorption occur.

Blind loop syndrome occurs when digested food slows or stops moving through part of the intestines, which leads to overgrowth of bacteria in the intestines, causing problems with absorbing nutrients.

• In 1924, Seyderhelm and others were able to produce artificially ahyperchromic anemia in dogs, who hadintestinal stricture and they could relate this anemia to the infection of the intestine. So, this is probably the earliest studies to have established absorption defects in blind loop syndrome, caused by infection.^[1]

Blind loop syndrome is a medical condition that occurs when the intestine is obstructed, slowing or stopping the progress of digested food, and thus facilitating the growth of bacteria to the point that problems in nutrient absorption occur.

It is divided into 3 types depending on the type of resection.

Blind loop syndrome ( short bowel syndrome) occurring after surgicalresection can be classified into 3 types depending on the type of resection.

• afterJejunostomy (end jejunostomy)
• Common reason
• dehydration starts immediately after surgery

• occurs afterJejunocolic anastomosis
• weight loss andnutrition abnormalities occur after months

• occurs afterJejunoileal anastomosis
• weight loss andnutritional abnormalities occur after months

Blind loop syndrome is a medical condition that occurs when the intestine is obstructed, slowing or stopping the progress of digested food, and thus facilitating the growth of bacteria to the point that problems in nutrient absorption occur.

The overgrowth of the bacteria in the intestine is prevented by the constant peristaltic movements of the bowel, and also by the presence of chemicals like gastric secretions, bile and pancreatic secretions.

Whenever there is obstruction to the constant peristaltic movements of the small intestine, either due toanatomical causes, surgical causes or physiological causes, it causes stagnation of the bowel contents, bacterial overgrowth in the small intestine leading to blind loop syndrome.

Due to the stagnation and decreased peristaltic movements, the digestive processes are disrupted, leading to malabsorption of bile salts, fat, fat soluble vitamins,carbohydrates, proteins.

Conditions associated with blind loop syndrome include:

• Achlorhydria
• dysmotility
• fistulae
• strictures

On gross pathology, distension of the bowl loop can be seen in the blind loop syndrome.

On microscopic histo pathological analysis, there can be injury to the intestinal wall.

The obstruction of a section of intestine causes ineffective bile salt mediated digestion of fats, causing fatty stools and poor absorption of fat andfat-soluble vitamins. CyanocobalaminVitamin B12 deficiency may occur because the increased bacterial population can consume the vitamin.

Blind loop syndrome is a medical condition that occurs when the intestine is obstructed, slowing or stopping the progress of digested food, and thus facilitating the growth of bacteria to the point that problems in nutrient absorption occur.

The causes can be divided into medical causes and Surgical causes.

The name of this condition refers to the “blind loop” formed by the blocked intestine. This blind loop does not allow the normal flow of digested food through the intestinal tract.

• after many operations, including subtotal gastrectomy.^[1]
• operations for extreme obesity
• .as a complication of inflammatory bowel disease,celiac disease,radiation enteritis
• Diabetes
• Scleroderma
• Small bowel diverticulosis

Blind loop syndrome is a medical condition that occurs when the intestine is obstructed, slowing or stopping the progress of digested food, and thus facilitating the growth of bacteria to the point that problems in nutrient absorption occur.

Blind loop syndrome should be differentiated from other diseases causing mal absorption, nutritional imbalances.

• Inflammatory bowel disease
• Diverticulosis
• Bowel obstruction
• Irritable bowel syndrome
• Malabsorption–Celiac disease

Afferent limb syndrome is one of the cause of blind loop syndrome, and is commonpostoperative complication. One study has estimated that it occurs in 13% of postpancreatico duodenectomy patients.

Afferent limb syndrome has decreased in incidence after introduction of newer surgical techniques.

There are many risk factors which can cause blind loop syndrome. All the factors which can cause disorders in motility can cause blind loop syndrome.

• Abdominal surgeries
• Gynecological surgeries
• Inflammatory bowel disease
• Diabetes
• Scleroderma
• injury in theintestinal wall.

There is insufficient evidence to recommend routine screening for blind loop syndrome.

If left untreated, almost all patients will develop nutritional deficiencies.

If left untreated, almost all the patients withblind loop syndrome may lead to poor nutrition. Blind loop syndrome can cause loss of vitamins and minerals, including vitamin B12.

• Complete intestinal obstruction
• Intestinal infarction (death of intestine)
• Perforation (hole) of intestine
• malabsorption and malnutrition

Majority of the patients get better with antibiotics and nutritional supplements.

If surgery is required, and patient undergoes surgery for the condition, then the prognosis is very good.
