Clinical Management of Intestinal Failure

Etiology and epidemiology Pathophysiology and clinical assessment Medical and surgical management Prevention and treatment of complications Nursing management Emerging diagnostic and therapeutic methods Long-term care. Reflecting the diverse nature of IF clinical care and research, this book is written by a group of expert clinician scientists that includes gastroenterologists, surgeons, nurses, pharmacists, dietitians, social workers, and patients. They show how a multidisciplinary approach to patient care is instrumental in achieving optimal patient outcomes through more efficient lines of communication, improved monitoring of medications and their effects, detailed evaluation of growth parameters, and facilitation of the creative process that can lead to research breakthroughs.

Advancing the discipline of IF, this book summarizes the current state of the art of patient management as well as new developments in the science of tissue engineering, medical and surgical therapy, and transplantation.

Water-soluble iodinated contrast is preferred to barium if perforation or a leak is suspected, as the extravasated barium can cause an inflammatory response in the peritoneum. Barium does, however, have a greater sensitivity for demonstrating enteric fistulae. This can help to assess the pathology underlying strictures or inflammation, which may be difficult to fully distinguish on radiological imaging alone.

This allows for an informed discussion with the patient about what surgery will entail and the risk of the requirement for PN postoperatively. If several fistulae are present, consideration to the timing of investigations is important to avoid confusion. Often a contrast study proximal to the fistula opening is examined first, otherwise defunctioned bowel containing contrast can degrade the image quality and lead to confusion of the anatomy. In patients with an ileal conduit or those with other complex past urological surgery, the anatomy of the urinary tract should be established prior to surgery.

The need for preoperative ureteral stenting should also be considered. Patients who have suffered extensive mesenteric ischemia and who have severe cardiovascular disease should be assessed preoperatively with a CT angiography to rule out insufficient blood supply to the gut. CT scanning of the abdomen will help to determine the size of any abdominal wall defect to aid surgical planning in terms of operating time, the requirement of a mesh, or even the need to have a plastic surgeon as part of the operating team.

These patients can have a complex anatomy that is difficult to define and establish. An experienced radiologist used to dealing in complex GI radiology is required to assess and review any imaging. Involving the radiologist early in the course can be beneficial with regard to radiology planning and choice of investigations. Often, all imaging will be reviewed in an multidisciplinary team setting with the surgeons, radiologists, and gastroenterologists before definitive surgery is planned, and a designated radiologist would be responsible for this complex cohort of patients.

Many patients with IF become dependent on large doses of analgesics, especially as the oral access for analgesia may be impaired. Chronic use of opioid and non-opioid analgesics is common in many patients with IF, especially in those with enterocutaneous fistula. Oral analgesia may not be appropriate in patients with a very short gut or obstruction. Intravenous access may also be difficult.

The use of patches can provide more sustained drug levels. Early involvement of a pain team with an understanding of the effects of analgesics on gut function, access to non-pharmacological distraction techniques, and a psychiatrist or psychologist with an understanding of addiction can be extremely helpful. It is also important to reduce analgesic requirements prior to surgical intervention, or postoperative pain control can be extremely difficult, with little scope for escalation of pain management if needed.

The management of pain after major open abdominal surgery relies on two techniques: Ideally, analgesic regimes should take into account periods where pain intensity is increased due to therapeutic interventions, e. Timing of surgery is an important consideration for IF patients. In a complex or open abdomen, it is thought that the process of forming a new peritoneal cavity takes around 6 months. Up to this point, the abdomen is still extremely hostile, and surgery puts the patient at risk of further injury and complications.

The advantage of bringing the distal bowel into continuity has to be weighed against the risk of an anastomotic leak. Surgery for type 2 IF is usually life changing, rather than life saving in the short term, and patients have to be counseled appropriately regarding this. In the long term, the advantages may include reduction or cessation of PN with avoidance of the associated risks.

The surgery itself should be allocated plenty of time. Careful dissection, with adequate time examining the bowel prior to closure, should be performed to reduce the risk of an enterotomy. Every serosal tear should be repaired, and any anastomosis should be performed meticulously. The anastomosis should not be placed within an abscess cavity, nor near an incision. A hand-sewn, 2-layer anastomosis reduces the risk of recurrence of fistula marginally when compared with a stapled anastomosis.

In these cases, a proximal defunctioning stoma may be worth considering. Patients should be routinely booked into a high dependency unit postoperatively, and adequate postoperative analgesia prescribed. Abdominal wall reconstruction may be a vital component of these operations, especially if the patient has had a previous laparostomy. Failure to gain closure of the abdominal wall properly may lead to re-fistulation, formation of a large incisional hernia, and poor cosmetic result.

These operations should, therefore, be performed in a specialist center, 1 where the surgical and anesthetic teams are used to dealing with such complex cases and any complications that could arise. The use of mesh may be required due to the presence of multiple defects, a large midline defect with poor rectus bulk, or a history of previous component separation.

The evidence for the safety and efficacy of nonabsorbable mesh in the open abdomen with enteric fistulization is limited, but it is thought to be associated with increased infection rates. There is evidence that simultaneous fistula surgery and abdominal wall reconstruction should not be performed with a non-absorbable mesh or cross-linked collagen mesh. Techniques employing autologous tissue such as component separation and primary repair are recommended.

They should be avoided in a contaminated environment. If it is not possible to bring together the abdominal wall, even with a component separation, or if a mesh is required in a contaminated field, a non-cross-linked biological mesh should be used.

Most biological meshes used outside the abdominal cavity lead to seroma formation, and drains should be left in the abdominal wall until dry, even if this amounts to several weeks. Intestinal transplantation offers a rescue therapy for chronic IF patients, with indications for transplant falling into four categories:. A simulation study from the US comparing both home parenteral nutrition and intestinal transplantation for irreversible IF has shown that intestinal transplant marginally improved survival in those patients who had intestinal transplantation Three types of intestinal transplantation are currently available and include isolated small bowel, liver plus small bowel, and multi-visceral.

Although the patient is relieved of PN dependence, they endure close monitoring of their immunosuppression, more septic episodes, prolonged hospital stays, and often significant limitations on their personal life as a result. Consideration for intestinal transplantation should be discussed at an IF network meeting, 1 with the IF unit caring for the patient and the transplant team, and primary management of these patients should be provided by a center experienced in medical intestinal rehabilitation, nutrition, and transplantation of other solid organs.

Patients with type 2 IF are complex and time consuming, and have a protracted hospital episode. Regardless of the etiology, the management requires a considerable length of hospital stay and extensive multidisciplinary input. Dieticians, stoma therapists, nurses, microbiologists, pharmacist, radiologists, physiotherapists, anesthetists, pain specialists, psychiatrists, nutrition nurses, gastroenterologists, physicians, and surgeons all act together to provide an appropriate input to the patients care throughout their hospital admission, their outpatient rehabilitation, and in the buildup to their definitive reconstructive surgery.

Restorative surgery should be deferred where possible until the patient is nutritionally stable, mobilizing, and medically and psychologically optimized. In the preoperative phase, patients should be given the opportunity to meet with an anesthetist to address any comorbid issues. Issues regarding postoperative pain relief, nutritional support, and intravenous IV access should also be addressed. The gastroenterology team is crucial in the preoperative workup of all IF patients, but especially those with underlying inflammatory bowel disease for control, or correction of their underlying condition and postoperative disease management.

In patients with a fistula, other specialties, such as urology, gynecology, and plastic surgery, may also be involved. This multidisciplinary team approach is also vital in the postoperative phase of the patient management. The majority of IF patients will have depleted lean muscle mass.

Therefore, an active, graded mobilization program is needed to help expedite recovery. The patient and their family often have anxiety, a feeling of loss, loss of self-esteem, depression, and anger, particularly if they developed type 2 IF secondary to a postoperative complication.

They may develop body image issues related to stomas, fistulae, and an open abdomen. IF can also have huge financial implications, as the patient suffers a loss of earnings and financial hardship. This may prevent the impact of further psychological complications later. It is also important to provide explanations to the patient at each stage of their recovery, as a number of them may have spent prolonged periods in hospital and had numerous investigations and invasive interventions, without fully understanding the reason for each step.

Patients are often frustrated, do not understand the benefit of waiting to get conditions optimal prior to surgery, and should participate in discussions surrounding their care. The ward nursing staff, specialist nutrition nurses, and the nutrition support team are majorly involved in the delivery of care to these patients.

The nutrition support team are an essential part for any patient, and usually will act to facilitate the transition of patients care from in-patient to out-patient. If possible, patients with type 2 IF should be discharged home prior to their surgery, 1 provided that home PN, complex wound care, supervision of home care, and regular monitoring of out-patients are available.
