Short Bowel Syndrome (Short Gut)

 

Below are recommendations and tips in the management of patients with symptoms related to relatively short small intestinal length (short bowel syndrome, short gut). Management should include multidisciplinary care and may require referral to a specialty center.  Many thanks to Dr. Abigail Martin, UK Pediatric Surgery, for sharing this document. 

Short Gut Syndrome Overview:

-          Patients with short gut have improved outcomes when being followed by an interdisciplinary, consistent team at an intestinal rehabilitation center

-          Patients with chronic/irreversible short gut syndrome will be dependent on parenteral nutrition for the remainder of their lives

-          Long term comorbidities include:

o   Parenteral nutrition associated liver disease (PNALD)

o   Intestinal failure associated liver disease (IFLAD)

o   Complications from need for long term central venous access (mainly infectious, thrombotic)

-          Teduglutide may be used to treat short gut syndrome and possibly reduce dependence on parenteral nutrition by promoting mucosal growth and possibly restoring gastric emptying and secretion. This is easier to obtain when working with an intestinal rehabilitation center

-          Indications for intestinal transplant:

o   Presence of liver failure from parenteral nutrition

o   Significant line complications including frequent CLABSIs or loss of central access due to thrombosis of veins

o   Frequent hospitalizations to control the sequela of short gut syndrome (such as dehydration or electrolyte imbalances)

-          Early involvement of Palliative Care will help with long term decision making and to discuss the long term issues that pertain to short gut syndrome

 

Care Team Planning for Newly Diagnosed Short Gut:

-          Recommend GI consult while inpatient

-          Identify which team will manage home parenteral/enteral nutrition

-          Ensure case management and social work is notified to prepare for home health nursing and home parenteral nutrition

 

Anatomy:

-          Undergo UGI/SBFT study in one year from diagnosis to establish baseline anatomy

-          If concerned for IFALD/PNALD or if patient is having any other abdominal surgery in the future, perform needle biopsy using 18 Ga needle of the liver

 

Parenteral Nutrition:

-          Cycle parenteral nutrition as soon as possible to decrease risk of PNALD, better QOL

o   Goal of 12-16 hour cycling schedule before discharge home (most patients end up discharging on 16 hour cycling schedule)

o   Goal over time of 10-12 hour cycling schedule

-          Consider Omegaven in Peds and SMOF in Adults if developing evidence of IF associated cholestasis (Dbili >2 for 2+ weeks)

-          In newly diagnosed patients, all estimated nutritional needs should be provided via parenteral nutrition until weight maintenance is demonstrated

 

Gastric Feeds:

-          Benefits of tube feeds (especially continuous low volume feeds):

o   Stimulation of intestinal mucosa to improve growth/absorption

o   Allows for more total enteral calories and less parenteral calories

o   Sometimes better tolerated for stool volume or potential dumping

-          Discuss NGT vs gastrostomy tube with patient

 

Oral Feeds:

-          Volume limited by titration to goal of 4-6 soft, formed stools daily

-          Do not continue a clear liquid diet other than water and no-sugar drinks

-          Consult with dietician about education for short gut syndrome diet

-          Plan on 6-8 small meals per day

-          Limit fluids to <4 ounces per meal

-          Take soluble fiber preferentially, avoid insoluble fiber

-          Avoid sugary and sugar-substitute containing foods as this may worsen diarrhea

 

Nutritional Supplementation:

-          Will need life long monitoring for micronutrients, vitamins, minerals

-          Evaluated at 6 month mark by home infusion plan and TPN modified accordingly

-          Consider starting Juven BID once PO is allowed, unless it contributes to dumping syndrome

 

Stooling:

-          Goal of 4-6 soft but formed stools daily

-          Daily fluids should be adjusted to meet stooling goals

-          Add pectin and/or fiber to help bulk up stools and prevent diarrhea

-          Start Imodium to help thicken stools, many patients require high doses daily

-          Consider cholestyramine of pectin, fiber, and Imodium do not help solidify stools

o   Cholestyramine will benefit patients without a terminal ileum or intact colon most

 

Bacterial Overgrowth:

-          Primary IF care providers should monitor for need of cycling oral antibiotics

-          Probiotics should be used with caution as may cause CLABSI/bacteremia

o   Administer probiotics separately from parenteral nutrition

o   Ideally a different person that does not care for and hang the parenteral nutrition should be administering the probiotics

-         Consider famotidine 80mg in parenteral nutrition to help decrease level of gastric acid secretion, as this can sometimes make stooling worse. IV PPI is not compatible in the TPN, and PPI tablets may not be absorbed as well.
