Mrs. O � � � 67 yo woman Ovarian cancer S/P multiple interventions, peritoneal mets, now with MBO Admitted from acute care hospital in late October to inpatient hospice unit Family told by previous physicians she only had “hours, maybe a day to live” Patient delirious, in distress with abd pain and nausea

THE SCOOP ON POOP Grace Varas DO Wake (6)

What’s It All About? � � � The Gastrointestinal Tract: Teeth to tail: 30 feet Function: to take in food and liquids, extract useful nutrients, and expel waste Many enzymes, proteins, hormones, organs, and muscles in an intricate dance The GI tract communicates with other organs (including brain)

THE SCOOP ON POOP Grace Varas DO Wake (7)

Let’s Start at the Very Beginning � � � Dentition: critical to tearing and grinding food. Oropharynx: salivary glands produce digestive enzymes that begin digestive process Esophagus: first of muscular tubular structures that propels food along gi tract. (esophagus about 1 foot) Transit time: 13 seconds

THE SCOOP ON POOP Grace Varas DO Wake (8)

Next…. . � � � Stomach: Acids to dissolve food and continue digestion--Strong muscular organ that mixes and threshes food. Time: 2 -4 hours Duodenal bulb next. (stomach through second portion of duodenum also 1 foot) Food passes to…….

THE SCOOP ON POOP Grace Varas DO Wake (11)

The colon continued… � � � Material is transported via segmenting contractions and propagating contractions By 24 hours, stool has made it to transverse colon By 48 hours, stool has made it to descending colon and sigmoid rectum

THE SCOOP ON POOP Grace Varas DO Wake (12)

Rectum and Anus--The End! � Defecation is evacuation of fecal material from rectum. Combination of voluntary and involuntary actions. � Stool fills rectum, causing distension � Straightening of anorectal angle (90 deg) � Involuntary relaxation of Int Anal Sphincter � To pass stool, puborectalis muscle holds angle and Ext Anal Sphincter relax

THE SCOOP ON POOP Grace Varas DO Wake (13)

What about Endangered Feces? � � What composes feces? Feces is composed primarily of water (75%) Remainder: 1/3 dead bacteria, 1/3 residue (fiber), balance: sloughed cells from intestine, bilirubin, fats, salts When people don’t eat, do they still make feces? YUP.

THE SCOOP ON POOP Grace Varas DO Wake (14)

Don’t forget the other stuff! � � � � Digestive enzymes from salivary glands, pancreas, gallbladder, small intestine Amylase, proteases, lipase, disaccharidases Hydrochloric acid Bile (liver via GB) Mucus Hormones Gastric secretions 2 L/d

Malignant Bowel Obstruction � � � Common and distressing outcome in patients with abdominal or pelvic cancer. Any time in their clinical history 5. 5 to 51% ovarian cancer 10% to 28% colorectal cancer Other tumors: gastric, pancreatic, cervical, bladder, endometrial, mesothelial (of peritoneum), carcinoma, and melanoma

THE SCOOP ON POOP Grace Varas DO Wake (47)

Malignant Bowel Obstruction � � � Causes: postoperative adhesions, a focal malignant or benign deposit, or relapse or diffuse carcinomatosis. Classic symptoms: intestinal colic, continuous abdominal pain, nausea or vomiting. Patients must be selected for surgery or medical treatment of their symptoms based on their clinical status.

THE SCOOP ON POOP Grace Varas DO Wake (48)

MBO: Maladaptive coping mechanisms � Imagine that you have been very hungry. Your tribe finally hunts down a mastodon, and it is time for a feast. You gorge yourself, eating great chunks of meat and causing a temporary obstruction. Your body would respond in the following way: �Mechanoreceptors and chemoreceptors would be stimulated by the distention caused by the large build-up of food proximal to the blockage. �These receptors would tell your brain to stop eating. James L. Hallenbeck, M. D. Palliative Care Perspectives © 2003 by Oxford University Press, Inc

(Video) It's A Beautiful Day - Jamie Grace (with lyrics)

THE SCOOP ON POOP Grace Varas DO Wake (49)

MBO: Maladaptive coping mechanisms � � � The intestine proximal to the blockage would begin hypersecreting fluid, trying to flood the system and wash the intestinal contents downstream. Intestinal motility would increase, further trying to push contents downstream and causing cramping. With luck, you would live to hunt another day. � While this approach works well for ingested mastodons, it works poorly for malignant bowel obstruction. James L. Hallenbeck, M. D. Palliative Care Perspectives © 2003 by Oxford University Press, Inc

THE SCOOP ON POOP Grace Varas DO Wake (50)

Pathophysiology of Malignant Bowel Obstruction (MBO) � � � A delicate balance of fluid absorption and secretion from and into the lumen is normally maintained. Studies have demonstrated that with MBO the balance is shifted strongly in favor of secretion. Increased secretion of fluid results in further intestinal dilatation, cramping, and frank nausea and vomiting.

THE SCOOP ON POOP Grace Varas DO Wake (51)

Pathophysiology of Malignant Bowel Obstruction (MBO) � � A vicious cycle is entered wherein hypersecretion (associated with cramping in the early stage) is followed by dilatation and vomiting, followed by further secretion and vomiting. Dehydration and electrolyte disturbances quickly result, leading to death (and misery) if an intervention is not made

James L. Hallenbeck, M. D. Palliative Care Perspectives © 2003 by Oxford University Press, Inc.

THE SCOOP ON POOP Grace Varas DO Wake (53)

Traditional Medical Approaches � � Traditional "conservative" management, "drip and suck" therapy (IVF w/ NGT => traditional peri-operative management for obstruction) No data that supports this approach as a long-term therapy for malignant bowel obstruction. Multiple studies have shown dismal outcomes with this approach alone. Theoretically, IV hydration, in addition to restoring intravascular volume, also increases hydrostatic pressure in the villi and therefore could increase secretion into the lumen, contributing to the “vicious cycle” (distension-secretion)

THE SCOOP ON POOP Grace Varas DO Wake (54)

The Dynamic MBO � Bowel obstruction is a very dynamic process, frequently reverting from total to partial obstruction and back in as many as 50% of cases.

THE SCOOP ON POOP Grace Varas DO Wake (55)

Early Palliative Approaches � � � Early palliative approaches stressed symptomatic relief. Assumed that the gut was nonfunctional, and therefore no attempt was made to normalize function. Symptomatic relief sometimes put the gut to sleep. Anticholinergic drugs both decreased secretion into the gut and decreased motility, thereby alleviating cramping. � Opioids were also stressed, both to reduce motility and treat pain directly. � These approaches are still used when normalization of gut function is impossible, as it often is in very proximal gut obstruction. �

THE SCOOP ON POOP Grace Varas DO Wake (56)

Early Palliative Approaches � Steroids have been used in the hope of relieving obstruction by reducing swelling around obstructing growths, although their efficacy in this regard is debatable. � Only one controlled study of the use of steroids in bowel obstruction has been done. It showed no evidence that steroids were helpful in reducing the degree of obstruction. A major problem in this study was the very high rate of spontaneous conversion from total to partial obstruction. � Steroids may nevertheless be useful in bowel obstruction by decreasing bowel and peritoneal inflammation and by acting as appetite stimulants.

THE SCOOP ON POOP Grace Varas DO Wake (57)

Recent Approaches � � � Recent approaches have tried to normalize gut function to the extent possible in addition to palliating symptoms directly. The ability to normalize and use the proximal gut is highly dependent on the level of obstruction. Many cases of malignant obstruction have multiple sites of obstruction, most frequently in the jejunum or ileum.

THE SCOOP ON POOP Grace Varas DO Wake (58)

Recent Approaches � � � It is not uncommon to have many feet of potentially functional intestine proximal to the rate-limiting site of obstruction. Very proximal obstructions prohibit normalization. However, very proximal and very distal obstructions may be amenable to stent placement that results in significant palliation by forcing open the gut lumen using an expandable wire mesh stent.

THE SCOOP ON POOP Grace Varas DO Wake (59)

� � � Surgical evaluation should be considered on all patients with MBO, though not all patients are candidates for surgery. Surgery carries a high perioperative mortality rate (10%– 20%), high complication rate (20%– 40%), and the potential for re-obstruction. Poor prognostic factors include recent laparotomy, carcinomatosis, and massive ascites.

THE SCOOP ON POOP Grace Varas DO Wake (60)

� � � Relative contraindications are widespread tumor, advanced age, extra-abdominal symptomatic metastases, poor nutritional status, and previous radiotherapy. Stents can be useful for lower bowel obstruction but not for the more common higher obstructions except very proximally. A venting gastrostomy may be helpful for longterm decompression

THE SCOOP ON POOP Grace Varas DO Wake (61)

Octreotide � An analogue of the hormone somatostatin, it significantly reduces secretion into the gut. � � � Study by Mangili, 13 patients with ovarian cancer-related obstruction had NG aspirate volumes measured. Mean drainage decreased from 1687 ml/day to < 50 ml/day. Similar significant results been repeated in studies by Mercadante and Shima. Somatostatin inhibits secretion of GH, TSH, ACTH and prolactin and decreases the release of gastrin, CCK, insulin, glucagon, gastric acid and pancreatic enzymes. It also inhibits neurotransmission in peripheral nerves of the GI tract leading to decreased peristalsis and a decrease in splanchnic blood flow.

THE SCOOP ON POOP Grace Varas DO Wake (62)

Octreotide � � � Octreotide may prevent the pathologic alterations of bowel obstruction in cancer patients by inhibiting the release of vasointestinal peptide, reducing gastrointestinal secretion and motility, decreasing splanchnic flow, and increasing the absorption of water and salts. Octreotide is generally well tolerated. It appears to have minimal effects on motility. Dose: 150 -300 mcg/day, either in divided SQ q 8 or in continuous drip

THE SCOOP ON POOP Grace Varas DO Wake (63)

Octreotide � � � Octreotide can result in significant improvements in nausea and vomiting; this appears to be due to decreased secretion of fluid into the gut. Improvement often occurs in 24 to 48 hours. A long-acting depo version of octreotide has been developed. (Role in chronic intermittant/MBO? $$$)

THE SCOOP ON POOP Grace Varas DO Wake (64)

� � Patients received a drug combination composed of metoclopramide 60 mg/day, octreotide 0. 3 mg/day (100 mcg TID), and dexamethasone 12 mg daily. with hydration (1200 -1500 ml/d) and morphine or transdermal fentanyl Study of 29 consecutive patients with inoperable MBO, this combination produced a 90% recovery rate. The treatment not only reduced gastrointestinal symptoms (vomiting) but also allowed for the restoration of intestinal transit and re-initiation of oral feeding. Maintenance of this treatment prevented further episodes. Upon discontinuation of treatment, symptoms recurred. Patients maintained on the combination had survival prolonged from 75 days (with placebo) to 187 days. Mercadante S et al. J Pain Symptom Mgmt 2004; 28: 412– 416

THE SCOOP ON POOP Grace Varas DO Wake (65)

Promotility agents � � � Promotility agents can be used if cramping is not present and if the intention is to normalize and use the proximal gut. Clinicians have believed that promotility agents are contraindicated in bowel obstruction traditionally because increased motility could worsen cramping and theoretically result in gut perforation. Reports of the beneficial effects of promotility drugs are beginning to appear in the literature.

THE SCOOP ON POOP Grace Varas DO Wake (66)

Promotility agents � � Metoclopramide is the drug of choice for this purpose. Metoclopramide works by binding 5 HT 4 receptors and releasing acetylcholine, which in turn binds cholinergic receptors and results in increased motility. Concomitant use of drugs with anticholinergic effects, such as scopolamine, promethazine, or amitriptyline, may antagonize this action and reduce efficacy. Dosing is usually begun at 5 -10 mg TID AC PO and gradually increased. For large bowel dysmotility a combination of metoclopramide with a large bowel stimulant, such as senna, will probably have to suffice until new motility agents are identified.

THE SCOOP ON POOP Grace Varas DO Wake (67)

Direct antiemetics � � � If cramping/colic is present or if the intent is to rest the bowel, as with patients no longer capable of eating or drinking, anticholinergic and antihistaminic antiemetics such as promethazine may be used. Glycopyrrolate, a more locally acting anticholinergic drug, can be given orally or parenterally. It can reduce cramping, intestinal secretion, and nausea. If the goal is to normalize gut function, anticholinergic agents should be avoided, because they both inhibit motility and block the use of metoclopramide. 5 HT 3 antagonists, such as ondansetron, may be the agents of choice for nausea, based on the limited data presented above suggesting 5 HT 3 -mediated nausea and the fact that they have limited effects on motility.

THE SCOOP ON POOP Grace Varas DO Wake (68)

NG/venting gastrostomies � � � NG tube placement can be very helpful for initial gut decompression. Venting gastrostomies have been used as a long-term alternative to NG tubes for decompression. No studies have compared venting gastrostomies to long-term octreotide therapy. �A consensus panel of the European Association of Palliative Care recommended that venting gastrostomies be used only if medications fail to control nausea.

THE SCOOP ON POOP Grace Varas DO Wake (69)

Opioids � � � Opioids are very effective in dealing with the cramping of bowel obstruction and are usually needed for pain management associated with advanced malignant disease. However, they can have undesirable effects on motility if one is trying to normalize gut function. As a general rule, pain management trumps motility management (but patient goals should be addressed)

THE SCOOP ON POOP Grace Varas DO Wake (70)

Opioids � � The fentanyl patch may have a lesser effect on GI motility than do other agents. It is often preferred, as well, because the oral route is generally unreliable in bowel obstruction. Methadone is also a less constipating opioid and can be administered rectally if necessary.

THE SCOOP ON POOP Grace Varas DO Wake (71)

Psychosocial support � � Patients with distal obstruction often become distended, which alters body image and can be distressing. While most patients hate NG tubes, they can also become dependent on them and may resist suggestions to discontinue them. � � This may be because when they were initially placed they did provide relief. Such patients also probably fear possible tube replacement. NG Tubes, although discouraged as long-term therapy, may also represent medical caring, and thus patients and families may view suggestions to discontinue them as potential abandonment.

THE SCOOP ON POOP Grace Varas DO Wake (72)

Psychosocial support � � � The rationale for discontinuation of any therapy must be carefully explained. The inability to eat or drink normally causes an intense grief reaction in patients and families. Adjusting the diet to a low-fiber/low-residue liquid-based one, may allow nurturing to continue even in the presence of complete bowel obstruction.

THE SCOOP ON POOP Grace Varas DO Wake (73)

Back to Mrs. O � � 67 yo woman Ovarian cancer S/P multiple interventions, peritoneal mets with MBO Admitted from acute care hospital (without a PC team) in late October after a prolonged stay to inpatient hospice unit on my call Patient was delirious, in distress with abd pain and intractable nausea/vomiting. Family also in distress!

THE SCOOP ON POOP Grace Varas DO Wake (74)

What I did then… � � � � Octreotide 100 mcg SQ q 8 hours Placed NGT to LIWS Haloperidol for nausea & delirium Dexamethasone 12 mg IV qam NS IVF (50 cc/hr) Morphine scheduled & prn Reassured family we would aggresively treat her for comfort

THE SCOOP ON POOP Grace Varas DO Wake (75)

What happened next… � � � NGT output initially was >1 L in first 12 hours, decreased to minimal over 24 -36 hours Patient awoke, comfortable, pain controlled with prn meds On day 4, had a small BM (to the shock of family), and wanted to start drinking fluids, which I agreed to.

THE SCOOP ON POOP Grace Varas DO Wake (76)

What happened next… � � � Family asked about prognosis. I told them, “Well, I don’t know if I can guarantee New Years, but certainly seems like she’ll have a place at the Thanksgiving table. ” Multiple jaws hit the floor. Family told by previous physicians prior to discharge she only had “hours, maybe a day to live without surgery”

THE SCOOP ON POOP Grace Varas DO Wake (77)

What happened next… � � Patient did go on to live through Halloween, Thanksgiving, Christmas, New Years, and Valentines Day. She did require 2 short stays for recurrent MBO mgmt during this 5 month period at the inpt hospice unit. She died shortly before Easter, again under my watch. More importantly, her QOL was restored: she went on motorcycle trips with her husband, returned to a careful diet, and was pain-free most of the time. She called this her “bonus life on hospice care. ”
