A novel approach to diagnostic and therapeutic interventions in the peritoneal cavity is described. More specifically, a technique for accessing the peritoneal cavity via the wall of the digestive tract is provided so that examination of and/or a surgical procedure in the peritoneal cavity can be conducted via the wall of the digestive tract with the use of a flexible endoscope. As presently proposed, the technique is particularly adapted to transgastric peritoneoscopy. However, access in addition or in the alternative through the intestinal wall is contemplated and described as well. Transgastric and/or transintestinal peritoneoscopy will have an excellent cosmetic result as there are no incisions in the abdominal wall and no potential for visible post-surgical scars or hernias.

Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Some embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. The device comprises a capsule sized to be swallowed and pass through the intestinal tract. The capsule can include at least one guide tube, one or more tissue penetrating members positioned in the guide tube, a delivery member, an actuating mechanism and a release element. The release element degrades upon exposure to various conditions in the intestine so as to release and actuate the actuating mechanism. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

The invention discloses a method and a system for processing images based on photographing in vivo by a wireless capsule endoscopy or a video endoscope. The method comprise the following steps of: (1) continuously capturing two-dimensional reversed images of an intestinal canal inner wall through a reversed projection of a image sensor of the wireless capsule endoscopy or the video endoscope to the intestinal wall, and sending the two-dimensional reversed images with continuous sequences by a wireless sending device of the wireless capsule endoscopy or the video endoscope to an image processing device for storage; (2) identifying a superposition part of the continuous sequences of the two-dimensional reversed images obtained from the step (1) by the image processing device; and (3) cutting and splicing the superposition part of the continuous sequences of the reversed images by the image processing device to form a three-dimensional image which presents the whole intestinal canal inner wall. The method can reduce time on studying photographed images by medical workers and greatly improve diagnosis efficiency.

The invention claims a special primer for aided-identifying strains of lactobacillus and the application thereof. The special primer is composed of a primer pair A and a primer pair B; the primer pair A is composed of the DNA of the sequences 13 and 14 in the sequence table; and the primer pair B is composed of the DNA of the sequences 15 and 16 in the sequence table. The PCR amplification is carried out on the total DNA of the strain to be detected by using the special primer; if the PCR product can be amplified by the primer pair A or the primer pair B, the strain to be detected is the candidate strain of lactobacillus; if no PCR product is amplified by the primer pair A or the primer pair B, the strain to be detected is the candidate strain of non-lactobacillus. In combination with the denaturing gradient gel electrophoresis (DGGE) or the sequencing technology, the invention further determines that the strain to be detected is the specific strain of lactobacillus. By adopting the special primer of the invention and combining with the PCR and the DGGE, the planting condition of the probiotics on the intestinal wall of aquatic animal can be directly identified. The method is the fastest, simplest, most convenient and effective method at present.

Embodiments provide swallowable devices, preparations and methods for delivering viable cells (VC) into the GI tract including GI wall tissue or other tissue site. Particular embodiments provide a swallowable device such as a capsule for delivering VC into an intestinal wall or other site. The VC can be contained within a tissue-penetrating shell disposed in the capsule that protects the VC as they pass through the GI tract until they are inserted into GI tract tissue or other location. The shell desirably has shape, size and material consistency to be contained in a swallowable capsule, delivered from the capsule into solid tissue by the application of force on the shell and biodegrade within the solid tissue to release the VC into the tissue. Within the shell or other structure the VC can be maintained in a viability-sustaining gel that preserves the viability of the VC for selected time periods.
