So, there are different clinical applications that we could apply osteopathic manipulation to in
terms of GI presentations. So, irritable bowel syndrome is one. Irritable bowel syndrome is a
presentation where patients come in with complaints of potential abdominal pain, nausea, alternating
diarrhea, constipation. The etiology tends to be not very clearly defined but there are some
neurologic and possible muscular components to the disease process. There definitely are effects
to the autonomic nervous system. There are increased risk factors with patients with anxiety,
depression, personality disorders, there may be history of childhood sexual abuse or domestic
abuse in women. So, irritable bowel syndrome is a set of symptoms. It really needs to be a
diagnosis that you make after you excluded all the potential causes. There are autonomic nervous
system effects. Sympathetic nervous system tends to shut down the GI system and so there is
potential for parasympathetic rebound, overcompensation so there is pretty much an unbalance
of the sympathetic and parasympathetic systems and this then leads to varying symptoms that the
patient may have. So, remember to take a thorough history with your physical exam, osteopathic
structural exam to help you with finding the potential somatic dysfunctions that could help in
these cases. So, with potential osteopathic structural findings you want to check for any possible
facilitation especially in the thoracic spine, upper lumbar. Looking for Chapman points could also
potentially help. You also want to check for proper functioning of the lymphatic system and
checking the different diaphragms. Different treatments that could potentially help with irritable
bowel syndrome include trying to balance the sympathetic and parasympathetic. Remember we
said how irritable bowel presents with varying symptoms of what seems to be hypersympathetic
tone and then at times a rebound hyperparasympathetic tone. So potentially if we remove any
sort of restrictions to try to balance autonomic tone, that might help these patients. So, for
parasympathetic balance, checking the OA and upper cervical for the vagus nerve and also checking
the sacrum for the pelvic splanchnics. We also want again to check for Chapman reflexes. Remember
Chapman reflexes for the small intestines anteriorly are in the bilateral intercostal spaces of
ribs 8 to 10, and also for the colon it is bilaterally along the IT bands. You could also check the
spinal junctions and check for Zink patterns to promote lymphatic drainage and help with improving
lymphatic flow from the GI tract and also check for any sort of postural dysfunctions. Again,
spinal dysfunctions on a posture could affect the entire abdominal container and treating those
could help our patients. So, overall with treatment, you want to apply osteopathic treatment
to the different dysfunctions that you may find. Treating facilitated segments first could be
helpful in treating irritable bowel syndrome. So, some possible treatments that you could utilize
include utilizing gentle inhibitory pressure, using indirect fascial release, taking a look at
different somatic dysfunctions of the spine and utilizing facilitated positional release or utilizing
balanced ligamentous tension on those spinal restrictions. Balancing the spine sometimes will
also help with the muscular attachments to it and the diaphragms. You could screen for counterstrain
points. Patients with irritable bowel may have corresponding counterstrain points especially
the anterior lumbar points near the anterior ASIS and posteriorly in the lumbar region. One
could use muscle energy, soft tissue, articulatory techniques again to the different somatic
dysfunctions that you may find. Ganglion inhibition might have a good role here so ganglion
inhibition, remember we talked about the different ganglion of the abdomen that supplies
sympathetic innervation to the gut and so we could apply some gentle inhibition over the ganglion
to try to normalize sympathetic tone and again looking at Chapman reflexes to break that
visceral somatic cycle and to decrease facilitation. Here is a chart looking at the different
Chapman points of the lower GI tract and so again with these Chapman points there are visceral
somatic reflexes and usually what you are looking for is your feeling for a tissue texture change
underneath your fingers at these different locations and if you do find it then treatment starts
with treating the pelvis and then applying a gentle inhibitory pressure, circular pressure on
that point for 30 seconds until the nodule kind of dissolves. So, looking at these different points,
it is important to remember that the anterior ones are easier to diagnose and then treatment,
usually you treat the anterior and sometimes also the posterior points if present. So, here is a
schematic of the Chapman points for the large intestine. So an easy way to remember how the Chapman
points lie for the large intestine is that you are kind of cutting at the transverse colon and then
reflecting the large intestine onto the IT bands on both sides and so you are kind of reflecting
downwards. So my hepatic flexure on the right side will be more closer to my right knee whereas
my ileocecal valve will be more towards my right hip and then on the opposite side my splenic
flexure will be reflected down closer to the left knee and my sigmoid and anal region will be
more reflected by the left hip and so when you are trying to identify the Chapman points you
may feel a little bit of a nodular tissue texture change along the lateral aspect of the IT bands
along the legs on either side. So colic is another GI presentation that potentially could be
treated with osteopathic manipulation. Colic usually has no cause or etiology. It's important
to rule out other potential causes for babies to be uncomfortable, perhaps they have an allergy
to the formula or something else that potentially be irritating their GI tract but if there is any
other pathology ruled out, colic really is just a symptom having increased crying and irritability.

There are a lot of different factors that could play a part and usually the onset is about 2 to 3
weeks and usually there is resolution by 3 months. Treatment usually includes trying to pacify,
nurse, support the baby until they stop crying. So, with osteopathic manipulation, first we
want to take a thorough history especially birth history, development to see if there are any
birth traumas, perform a thorough physical exam looking at potential regions that may contribute
to colic. Key areas to diagnose include the cranium especially the cranial base and the upper
cervical. So in our pediatric patients, our babies, the craniums undergo a lot of stress and trauma
during development in the womb where there may be certain pressures on the head and also through
delivery if there was a vaginal delivery then the head goes through a lot of molding and compression
and so these are some key areas to take a look at with infants especially if there was some
sort of trauma related to the birth itself whether or not they had to vacuum or if there was a
prolonged labor. This may cue you in to potential somatic dysfunctions being more present in
the cervical and cranial region. So, definitely take a look at the occiput, the occipitomastoid
suture. Remember that the jugular foramen lies along that suture and cranial nerves IX, X and
XI are in that region. Also, the hypoglossal passes by the occiput and the occiput undergoes a
lot of different forces during delivery. The occiput at birth is in 4 parts and so those condylar
parts can potentially be compressed. So it is really important to take a look at those specific
regions because those cranial nerves are ultimately responsible for the ability to suck and swallow
and also provides parasympathetic innervation to the GI. You also want to take a look at the
thoracic cage and diaphragm and also looking at these rib restrictions, that may potentially
affect the diaphragm and also scan and screen for possible viscerosomatic reflexes. So, when
treating, you want to treat what you find,take a look at the thoracic cage and to the cervical
biomechanic, look at potentially utilizing treatments to resolve any somatic dysfunctions in
those regions. For the cranial treatments, you could do some gentle OA decompression, suboccipital
release. Base spread is a good technique to try to really release the condyles and also the OM
suture. So, in general, colic cases may have potential contributions from mechanical causes. So,
these osteopathic somatic dysfunctions usually go unrecognized and there is a potential improvement
that patients can have with the incorporation of osteopathic manipulation to the treatment of colic.
