Abstract: Methods and systems are provided for diagnosis and possibly treatment of the large intestine, using samples from at least three portions of the large intestine, including sampling the ascending proximal portion thereof. Samples from the ascending portions of the large intestine were found to differ in their microbial characteristics significantly from prior art stool samples and from samples taken from the descending and transverse parts of the large intestine—enabling more accurate diagnosis and possibly more effective treatment of diseases of the large intestine.

Abstract: Systems and methods are provided to limit abdominal distension and alleviate uncomfortable side effects related to it—in patients treated in hydrocolonic preparation units. Systems may comprise a water delivery unit comprising a controllable water supply, configured to introduce water controllably into the patient's large intestine, a drainage configured to drain, by gravity, the introduced water with contents of the patient's large intestine and a controller. The drainage comprises a drainage pipe and sensor(s) such as camera(s) configured to continuously measure the amount of drained water drained by the drainage pipe. The controller is configured to control the water introduction with respect to the measured amount of drained water, keeping an amount of water retained in the patient below a specified water retention threshold to reduce uncomfortable side effects of abdominal distension.

Abstract: Methods of image analysis of large intestine contents for diagnosis and treatment are provided. Methods include introducing water controllably into a patient's large intestine, draining, by gravity and using a transparent drainage pipe, the introduced water with contents of the patient's large intestine, capturing images of the drained contents, optically through the transparent drainage pipe, and analyzing the captured images to extract diagnostic parameters therefrom. In addition, samples of the drained contents may be stored to form a stool bank and microbiome characteristics may be derived to suggest corresponding microbiota transplants.

Abstract: Systems are provided which analyze the large intestine contents and utilize acoustic signals detected during delivery of water into the large intestine and drained large intestine contents to derive large intestine characteristics such as microbiotal analysis from at least two portions of the large intestine. Systems may include a water delivery unit including a water supply and a nozzle connected thereto, configured to introduce water controllably into a patient's large intestine, and an analysis unit that provides information about the drained contents using optical examination or biological assays. The information may be related to acoustic analysis of signals from acoustic sensors that are attachable to a patient's abdomen. A variety of sensor configurations, positioning options, analysis strategies and large intestine characteristics are presented.
