GENERAL PRINCIPLES

• The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult. Bowel obstruction may be permanent or intermittent; complete or partial; acute or chronic and may occur at any point along the gastro intestinal tract.

• Bowel obstruction may be caused by intrinsic or extrinsic mechanical obstruction or an abnormality in gut motility

Page 6: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

• Patients with small bowel/high intestinal obstruction are likely to experience the symptoms of vomiting and abdominal colic.

• Patients with large bowel/low intestinal obstruction are likely to

experience the symptoms of abdominal distension and constipation

• If the lumen of the gastrointestinal tract is occluded, fluid secreted

by the bowel wall accumulates within the lumen. This results in bowel distention and stimulates release of further fluid from the gastrointestinal tract.

• The management of bowel obstruction in advanced cancer may

be medical or surgical, or a combination of both approaches. The aim is to control symptoms including nausea, vomiting and abdominal pain.

Page 7: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

• If the obstruction is thought to be complete, prokinetic agents and

stimulant laxatives should be discontinued. If the obstruction is sub-acute or incomplete, then it may be appropriate to use prokinetic agents, rectal measures and softening laxatives providing the patient is not describing abdominal colic.

• During the medical management of bowel obstruction, the majority

of patients may be adequately hydrated with small amounts of oral fluid. If a patient develops persistent thirst, parental fluids may be an option.

• Surgical intervention may involve: the formation of a stoma,

bypass, resection, stenting or a venting gastrostomy.

Page 8: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

• Self-expanding metallic stents can alleviate malignant bowel

obstruction and should be considered for patients with single

level obstruction distal to the splenic flexure.

Page 9: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

GUIDELINES

Initial management • Rectal examination should form part of the initial assessment of

any patient with suspected bowel obstruction. Constipation should be excluded. If the rectum is empty an abdominal radiograph should be considered if appropriate [level 4]

• In obstruction of the small bowel, the bowel contents are liquid. In

partial large bowel obstruction, the use of movicol or idrolax may be helpful. However they should be discontinued in complete obstruction. Faecal softeners/gentle stimulants such as sodium docusate should be considered for partial obstruction. Stimulant laxatives should be discontinued. (See guidelines on the management of constipation) [level 4]

Page 10: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

GUIDELINES

• If the history is suggestive of low bowel obstruction, a trial of

metaclopramide should be considered to control symptoms of nausea and vomiting. [Level 3] It should not be used if there is intestinal colic. In patients where metaclopramide is contraindicated, alternative antiemetics to be considered are cyclizine/haloperidol or levomepromazine. [Level 4]

• Hyoscine butylbromide may be used to reduce gastointestinal

secretions and abdominal colic. Glycopyronuim is an alternative to hyoscine butylbromide. [Level 3]

• Octreotide may also be used to reduce gastrointestinal secretions

and is recommended as a second line option. Ocreotide may have a more rapid effect than hyoscine butylbromide. [Level 3]

Page 11: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

GUIDELINES

• In a patient with a high intestinal obstruction, consider the use of

an intravenous proton pump inhibitor as this may reduce the volume of gastrointestinal secretions e.g. Omeprazole 40mg intravenously once daily. Ranitidine via a continuous subcutaneous infusion has also been shown to reduce secretions. [Level 4]

• Corticosteroids may also help to achieve symptom control.

Consider a trial of dexamethasone 8mg subcutaneously for 5 days. Corticosteroids may have a favourable impact on the outcome of the episode of malignant bowel obstruction. [Level 2+]

Page 12: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

GUIDELINES

• Opioid analgesia and antispasmodics should be titrated to achieve

good pain relief [Level 4] • Table 9.1 illustrates the drug options available for the management

of bowel obstruction (see N&V guidelines) • A surgical opinion should always be considered as part of the

management of any patient with bowel obstruction. Factors associated with a more favourable outcome following surgery include:

• Single level of obstruction • Albumin 30g/l. • Absence of ascites • No previous oncological treatments in the last 6 months [level 2+]

Page 13: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

GUIDELINES

Management of resolving bowel obstruction

• If symptoms are controlled for 48 hours, or appear to be resolving, then

medication should be reduced to the lowest dose possible to maintain good symptom control. [Level 4]

• Prokinetic agents and laxatives may be considered at this stage [Level 4] • Laxatives are only of value in large bowel obstruction, bowel contents are

liquid in small bowel obstruction [Level 4] • Prokinetic agents such as metaclopramide may help promote gastric

motility [Level 4] • Some patients may be able to recommence oral medication if the

obstruction is relieved. [Level 4]

Page 14: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

GUIDELINES

Use of a nasogastric tube • Consider a wide bore nasogastric tube for patients with upper

gastrointestinal obstruction and/ or intractable large volume vomiting [Level 4]

Venting gastrostomy • A venting gastrostomy can improve the symptoms of malignant

bowel obstruction. It should be considered in patients with intractable symptoms who have a prognosis of >2 weeks. If a nasogastric tube has helped improve symptom control it is possible that a venting gastrostomy may also be effective [Level 4]

Page 15: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

STANDARDS

1. The multidisciplinary notes should record:

The finding of the rectal examination on initial assessment. The presence and severity of abdominal colic, nausea and vomiting. The number of vomiting episodes in 24 hours [Grade D]

2. Consideration of a surgical opinion and the decision should be documented in the case notes [Grade D]

3. Medication should be delivered by continuous subcutaneous infusion. Breakthrough medication can be given by stat subcutaneous injections [Grade D]

4. If a patient is experiencing abdominal colic, prokinetic drugs and stimulant laxatives should be discontinued [Grade D]

5. The frequency of vomiting should be reduced to one episode per 24 hours [Grade D]

THE USE OF CORTICOSTEROIDS IN HOME

PALLIATIVE CARE.

MERCADANTE ET AL (2001)1

• Characteristics; Longitudinal study of 50 patients. Administered corticosteroids if symptom intensity that could be improved by corticosteroids were graded 2 or 3 on a scale of 0 (not at all) to 3 (severe).

• Analysis; Paired Wilcoxon signed-rank test, P-values were two sided.

• Outcome; Intensity of symptoms subsequently graded as 0 or 1 (absent or light).

• Limitations; Patients did not have to have a malignant diagnosis, Only 10/50 patients had symptomatic nausea and unclear how many of those had bowel obstruction.

A PROSPECTIVE SURVEY OF THE USE OF

DEXAMETHASONE ON A PALLIATIVE CARE UNIT.

HARDY ET AL (2001)2

• Characteristics; Prospective survey of 106 patients.

• Analysis; Observational only.

• Outcome; Symptom score improvement for anorexia, nausea, pain, low mood, vomiting, and weakness.

• Limitations; Only 7 patients had intestinal obstruction, results for these 7 patients were not pulled out of the data set on reporting, patients did not have to have a malignant diagnosis, study not controlled for other interventions

CORTICOSTEROIDS FOR THE RESOLUTION OF MALIGNANT

BOWEL OBSTRUCTION IN ADVANCED GYNAECOLOGICAL AND

GASTROINTESTINAL CANCER.

COCHRANE DATABASE OF SYSTEMIC REVIEWS

FEUER & BRADLEY (2009)3

• Characteristics; Meta analysis (an update of a previous review on the same topic in 1999)

• Analysis; Nil

• Outcome; No new trials suitable for inclusion beyond these found used in the 1999 review, there is a trend for evidence that corticosteroids of dose range six to 16mg dexamethasone given intravenously may bring about the resolution of bowel obstruction (NNT 6), corticosteroids do not affect the length of survival

• Limitations; Trend is not statistically significant, based on 10 trials (3 unpublished RCTs and 7 published prospective and retrospective trials) accountable for 89 patients

THE USE OF STEROIDS IN THE MANAGEMENT OF INOPERABLE

INTESTINAL OBSTRUCTION IN TERMINAL CANCER PATIENTS: DO

THEY REMOVE OBSTRUCTION?

LAVAL ET AL (2000) 4

• Characteristics; Randomised, double-blind prospective study of 52 patients

• Analysis; Not specified

• Outcome; Symptoms of bowel obstruction were relieved in more of those patients taking steroids than in those taking the placebo

• Limitations; Outcome not statistically significant [p=0.08] (except in the subgroup of patients without an NG [p=0.047]), study not controlled for other interventions

Page 24: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

IN SUMMARY….

• There is a trend for evidence that corticosteroids of dose

range 6-16mg dexamethasone given intravenously may bring

about the resolution of bowel obstruction.3

• The incidence of side effects is extremely low.3

• Corticosteroids do not seem to affect the length of survival.3

• Response should be assessed within four or five days with a

view to discontinue if no benefit seen.4

Octreotide is effective in controlling vomiting in 60% malignant bowel obstruction cases regardless of type/level of obstruction2 Use of octreotide reduces NG aspirate volume, may avoid placement of NGT and allow removal of NGT1,2

Octreotide should be considered where rapid reduction is necessary1

Octreotide is more effective than hyoscine butylbromide in relieving gastrointestinal symptoms of advanced cancer and should be considered as first-choice anti-secretive drug despite the cost3

INTRODUCTION

Malignant bowel obstruction is a recognized

complication of advanced pelvic or abdominal

malignancy frequently occurring in the

advanced stages of illness1. Suggested

incidences of bowel obstruction in ovarian

carcinoma range from 5.5 to 42% and in

colorectal cancer 4.4 to 24%2.

The diagnosis of bowel obstruction is made

via history, physical examination and

radiological examination3 although in some

cases radiological examination may not be

appropriate.

Page 73: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

POWERPOINT PRESENTATION

JULY 2012

V1.0

These guidelines suggest a definition of

malignant bowel obstruction as follows:

(adapted from Anthony et al3)

• Clinical evidence of bowel obstruction

(via history/physical/radiological

examination)

• Intra abdominal primary cancer with

incurable disease

• Non intra abdominal primary cancer with

peritoneal disease.

Page 74: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

POWERPOINT PRESENTATION

JULY 2012

V1.0

Symptoms commonly associated with

malignant bowel obstruction include3:

• Abdominal pain

• Abdominal colic

• Nausea

• Vomiting

• Large volume vomits/ excessive GI

secretions

SCOPE AND PURPOSE OF

GUIDELINE

This guideline is aimed at practitioners in

palliative care including doctors, nurses and

pharmacists. The guidelines will also be of

benefit to generalist providers of palliative

care such as general practitioners, district

nurses and those in secondary care.

The aims of the guideline are to:

• Improve the medical management of

patients with malignant bowel obstruction.

• To help control the symptoms of bowel

obstruction in these patients.

SCOPE AND PURPOSE OF

GUIDELINE

These guidelines do not cover the surgical

management of malignant bowel obstruction

which may include a defunctioning stoma,

bypass, resection or stenting. It is expected

that the appropriateness of a surgical

opinion would be considered in all patients.

POWERPOINT PRESENTATION

ASSESSMENT

The pattern of presenting symptoms is usually determined by the level of obstruction. With high level obstruction (stomach, duodenum, pancreas, jejunum), vomiting develops early and can be frequent and large in volume [Level 4] 4. Distension may be minimal. In low level obstruction (large bowel), distension is more prominent and other symptoms develop progressively [Level 4] 4. Nausea, abdominal pain, colic and dry mouth can be present regardless of the level of obstruction [Level 4] 4.

The diagnosis is established on clinical grounds and may be confirmed with imaging (abdominal X-ray or CT scan) [Level 4] 4.

SYMPTOM CONTROL

Indications, doses and administration information relating to the medications cited in this section are presented in table 1.

Pain Opioid analgesia should be titrated to control continuous abdominal pain. A syringe driver is likely to be the most reliable route of administering this, although transdermal Fentanyl could also be considered [Level 4] 5.

Colic should initially be managed with the reduction or discontinuation of prokinetic drugs and stimulant laxatives. Followed by the addition of antispasmodic medication e.g hyoscine butylbromide or glycopyrronium

Page 79: MEDICAL MANAGEMENT OF MALIGNANT BOWEL OBSTRUCTION · GENERAL PRINCIPLES • The term “bowel obstruction” covers a range of clinical situations and diagnosis may be difficult.

POWERPOINT PRESENTATION

JULY 2012

V1.0

SYMPTOM CONTROL Reduction of secretions

All patients who experience vomiting should be prescribed anti-secretory treatment.6 [Level 1]. Octreotide is effective at reducing the number of vomits, nasogastric tube volume and may avoid placement of a nasogastric tube, it should be considered as the first choice anti-secretory. 6,7,8[Level 1]. Hyoscine butylbromide6,7 [Level 1] and glycoprronium9 [Level 3] are also effective at reducing secretion volume and may be considered second line.

POWERPOINT PRESENTATION

JULY 2012

SYMPTOM CONTROL Reduction of nausea and vomiting

Anti-emetics should be administered via a continuous subcutaneous infusion with additional doses administered subcutaneously for breakthrough symptoms.

One approach to anti-emetic prescribing is suggested below:

Partial bowel obstruction

Metoclopramide

Complete bowel obstruction OR partial bowel obstruction with colic 1st line - Cyclizine and/or Haloperidol

2nd line - Levomepromazine

SYMPTOM CONTROL

Corticosteroids

There is a trend for evidence that

corticosteroids may bring about the

resolution of bowel obstruction.10 [Level 1+]

Consider a trial of dexamethasone 8mg

subcutaneously for five days.11 [Level 1-]

Corticosteroids do not affect the length of

survival.10 [Level 1+]

SYMPTOM CONTROL

Venting gastrostomies or jejunostomies

Venting gastrostomies or jejunostomies should be considered for patients with unresolved, symptomatic, malignant bowel obstruction with a prognosis of greater than 2 weeks [Level 4]. They can be very effective at relieving nausea and vomiting 13 [Level 2]. They are better tolerated than NG tubes 14[Level 3]. This procedure may enable patients to eat and drink and to be cared for at home 13,15 [Level 2]. It is a cost effective procedure with low morbidity and mortality 15 [Level 3].
