Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to an energetic or nutritive composition intended for preparing the digestive tract prior to a physical check-up such as an endoscopic examination (flexible endoscopy or endoscopic capsule), radiological or a therapeutic intervention. 
       STATE OF THE ART 
       [0002]    Prior to an examination of the digestive tract, it is absolutely necessary that the latter be cleaned of stools which obstruct it in order to allow adequate viewing of the mucosa. 
         [0003]    Several classifications of the quality of the preparation have been established. (Eliakim et al. Evaluation of the PillCam Colon capsule in the detection of colonic pathology: results of the first multicenter, prospective, comparative study. Endoscopy 2006; 38(10):963-970,
   Vanner et al. A randomized prospective trial comparing oral sodium phosphate with standard polyethylene glycol-based lavage solution (Golytely) in the preparation of patients for colonoscopy. American Journal of Gastroenterology 1990; 85:422-427,   Barclay et al. Carbohydrate-electrolyte re-hydration protects against intravascular volume contraction during colonic cleansing with orally administered sodium phosphate. Gastrointestinal Endoscopy 2002; 56:633-8). According to Eliakim et al., it is possible to classify the preparation in different grades, from grade 1 (excellent preparation) to grade 4 (insufficient preparation compromising the quality of the examination). Vanner et al. propose another classification described hereafter: excellent preparation=small volume of clear liquid; good preparation=important volume of clear liquid; acceptable preparation=limited half-solid stools which can be sucked up or cleaned; insufficient preparation=half-solid stools.   
 
         [0006]    Poor preparation may therefore be detrimental to the quality of an examination, in particular in the case of an examination by flexible endoscopy, but also to the quality of a radiological examination where stools may mimic the presence of polyps, or in case of an examination by endoscopic capsule where the quality of the preparation has to be excellent since the capsule navigates in the liquid contained in the digestive tract which has to be perfectly clear (transparent) in order to allow viewing of the mucosa. 
         [0007]    In case of such an examination by endoscopic capsule, insufflation or suction of debris and/or of turbid liquid cannot be authorized, whereas the physician can actively intervene when a coloscope is used (e.g. suction to clean, go back). The latter represents a reason why in case of examination by endoscopic capsule, the quality of the preparation has to be excellent. Upon use of endoscopic capsules the digestive tract thus has to be prepared better than when using a coloscope to obtain the same quality of images. This is confirmed in the abstract of ‘Capsule Endoscopy versus Colonoscopy for the Detection of Polyps and Cancer’, N Engl J Med 2009; 361:264-70. 
         [0008]    All the procedures using colic compositions for flexible endoscopy or radiological examination (coloscan) foresee a diet without residues and administration of a laxative composition on the day before and/or the day of the examination. 
         [0009]    In order to obtain an examination of maximum quality, a clear liquid diet (a clear liquid diet consists of the intake of transparent liquid foodstuffs such as water, defatted broth, fruit juices without pulps (apples, white grape), clear lemonades, clear gelatin, coffee (without milk), tea (without milk), herbal teas) may be recommended during the whole day preceding the examination. 
         [0010]    The quality of the examination might further be improved if this clear liquid diet is also associated with the intake of laxative(s) during the 36 hours preceding the conduction of the examination. 
         [0011]    This type of prolonged administration of laxatives causes an important discomfort for the patient which is increased by the intake of a large amount of liquid together with a lack of supply of nutritive elements. This may give rise to lipothymias, malaise, nauseas related to fasting, altering the comfort of the patient and therefore his/her availability upon conducting the examination but therefore also lowering patient compliance with the diet prescribed by their physician in preparation of the check-up. All of the above can give rise to a suboptimal preparation and thus less reliable results, images for review and diagnosis. Further, laxatives have a salty taste which makes their ingurgitation unpleasant. 
         [0012]    Polyethylene glycol (PEG) represents the basis of most colic compositions, its macromolecules not being absorbed by the digestive tract, allow an increase in the volume of intestinal liquids. Accordingly, better hydrated stools transit faster in the colon and are more easily evacuated. Other laxatives such as sodium phosphates may also be used. 
         [0013]    Presently there are several laxative or colic compositions on the market: Colofort® (Ipsen), Colopeg® (Bayer), Endofalk® (Codali), Fleet® Phosphosoda (Kela), Klean-Prep® (Norgine), etc. Some of them attempt to solve the problem of unpleasant taste by adding aromas. 
         [0014]    In document US-A-20060073214, with the composition and/or the preparation method, the ingestion of large amounts of liquid tolerated with difficulty by the patient may be limited. 
         [0015]    The ideal preparation method would reliably empty the colon of all fecal material, have little effect on the gross or the microscopic appearance of the mucosa, require a relatively short period for ingestion and evaluation, cause little patient discomfort, and produce no significant fluid-electrolyte shifts while maximizing the detection of colonic disease. It becomes important to consider, in particular in the field of capsule endoscopy, to be able to give nutrients while preparations for long durations can be contemplated which remove any opaque liquid residue at colon level.

       Example of Use 
     Example 1 
       [0076]    In order to prepare the digestive tract to an endoscopic capsule examination where the quality of the preparation has to be good to excellent (grade 1 or 2 according to Eliakim et al.), the patient has to follow the following administration:
       In the evening two days before the examination, a sachet of composition 1 is made soluble in 1.5 liters of water and is administered to the patient.   The day before the examination, three sachets of composition 1 are made soluble in 3 times 1.5 liters of water and are administered to the patient during the whole day.   In the morning of the examination, a sachet of composition 1 is made soluble in 1.5 liters and is administered to the patient.       
 
         [0080]    This allows the patient to feed exclusively on this composition starting from two days before the examination. He/she should therefore not take in additional liquid. 
       Example 1 Bis 
       [0081]    In order to prepare the digestive tract to an endoscopic capsule examination where the quality of the preparation has to be good to excellent (grade 1 or 2 according to Eliakim et al.), the patient has to follow the following administration:
       In the morning and at noon two days before the examination, a contact laxative (e.g.: Senna Alexandrina syrup) is administered to the patient.   In the evening two days before the examination, a sachet of composition 1 is made soluble in 1.5 liters of water and is administered to the patient.   The day before the examination, three sachets of composition 1 are made soluble in 3 times 1.5 liters of water and are administered to the patient during the whole day.   In the morning of the examination, a sachet of composition 1 is made soluble in 1.5 liters and is administered to the patient.       
 
         [0086]    This allows the patient to feed exclusively on this composition starting from two days before the examination. He/she should therefore not take in additional liquid. 
       Example 2 
       [0087]    In order to prepare the digestive tract for a radiological examination (ColoScan) where the quality of the preparation has to be excellent or good according to Vanner et al., the patient follows the following procedure:
       One day before the examination, two sachets of the composition 1 are made soluble in two times 1.5 liters of water and are administered to the patient.   In the morning of the examination, a sachet of composition 1 is made soluble in 1.5 liters and is administered to the patient.       
 
         [0090]    This allows the patient to feed exclusively on this composition starting from the day before the examination. He/she should therefore not take in additional liquid. 
       Example 3 
       [0091]    In order to prepare the digestive tract for diagnostic examination with a colonoscope where the quality of the preparation has to be satisfactory, good or excellent according to Vanner et al., the patient follows the following procedure:
       One day before examination, two amounts of the composition 2 are made soluble in two times 1.5 liters of water and are administered to the patient.   In the morning of the examination, an amount of composition 2 is made soluble in 1.5 liters and is administered to the patient.       
 
         [0094]    This allows the patient to feed exclusively on this composition starting from the day before the examination. He/she should therefore not take in additional liquid 
       Example 4 
       [0095]    In order to prepare the digestive tract for a therapeutic intervention where the quality of the preparation has to be satisfactory, good or excellent according to Vanner, the patient follows the following procedure:
       The day before the examination, two amounts of composition 3 are made soluble in two times 1.5 liters of water and are administered to the patient.   In the morning of the examination, an amount of composition 3 is made soluble in 1.5 liters and is administered to the patient.       
 
         [0098]    This allows the patient to feed exclusively on this composition starting from the day before the examination. He/she should therefore not take in additional liquid. 
       Example 5 
       [0099]    In order to prepare the digestive tract for PillCam™ 0  Colon 2 (Given Imaging Ltd., Israel) where the quality of the (oral bowel) preparation has to be acceptable, preferably good or more preferably excellent according to Vanner, the patient follows the following procedure:
       Two days before the examination subject will have:
           base line serum electrolyte or ions and blood sugar or glucose level or glyc(a)emic index determined via collection of blood and   one liter of PEG solution in the evening, water (or any other of the above described clear liquids from the state of the art) at will.   
           One day before the examination, composition 4 is administered to the patient according to the following schedule:
           One liter PEG and 200 ml of the carbohydrate beverage of composition 4 in the morning,   400 ml of the carbohydrate beverage of composition 4 in the afternoon and   one liter PEG and 200 ml of the carbohydrate beverage of composition 4 in the evening.   
           On this day there is a total intake of about 2000 kcal: 2(2×247 kcal)+(4×247 kcal)=1976 kcal. One meal equals about 700 kcal.   Nil by mouth (to fast a patient) except water (or any other of the above described clear liquids from the state of the art) at will.   Day of the examination subject will have:
           base line serum electrolyte or ions and blood sugar or glucose level or glyc(a)emic index determined via collection of blood and   one liter of PEG solution after ingestion of the proprietary endoscopic capsule of the 1 st  paragraph of example 5.   
               
 
         [0112]    The above described (electrolyte-)PEG (solution) can be any or a combination of the above described compositions 1, 2 and/or 3 made soluble in the above described clear liquid from the state of the art. 
         [0113]    Healthy volunteers are subjected to the procedure of example 5 after which physicians review the generated RAPID video. The technology behind the endoscopic capsule is that it contains an imaging device and light-source and it transmits images to the sensor array attached to the patient&#39;s abdomen and to the data recorder attached to a belt around the patient&#39;s waist. Images for review and diagnosis are downloaded by the physician to the Given workstation, on which the proprietary RAPID software is installed. Grading is done using a scale for each segmental section of the colon and overall for the entire video, an excellent grade is given when there is no more than small bits of adherent feces, a poor grade when there is a large amount of fecal residue. The objectives of this clinical trial or study are a.o.: test the hypothesis that carbohydrate oral rehydration in combination with PEG would increase the patient tolerance to the bowel preparation, evaluate efficiency in colon cleansing (or the colon cleansing level) of combination of electrolyte-PEG solution and the carbohydrate beverage of composition 4 for proprietary endoscopic capsule of the 1 st  paragraph of example 5, to evaluate patient adherence to the combined regimen, to evaluate patient tolerance to the combined regimen, to evaluate the effect of the regimen on capsule transient time, . . .
