Aim: Colorectal resection in women with endometriosis involving the low and mid rectum may result in a poorer outcome than conservative procedures. In this technical note we present a new technique for transanal full thickness disc excision of endometriosis nodules involving the rectum.
Method: The procedure is performed by combined laparoscopic and transanal routes. The former involves paring the area of the rectum infiltrated by the nodule, which is then made amenable to endoluminal removal using the Contour Transtar stapler to carry out a large disc excision.
Results: The technique can remove a specimen as large as 80 mm in diameter and can be applied to patients with infiltrating rectal endometrial nodules up to 10 cm from the anal margin and 50-60% of the rectal circumference. The procedure is probably less likely to lead to rectal stenosis and denervation than colorectal resection.
Conclusion: This technique of transanal rectal disc excision using the Contour stapler is suitable in patients with infiltrating deep endometriosis nodules of the lower and mid rectum. It avoids a low rectal resection with its potential complications and unfavourable function.

Backgroud: Intervertebral disc degeneration (IDD) is one of the common degenerative diseases. Due to ethical constraints, it is difficult to obtain sufficient research on humans, so the use of an animal model of IDD is very important to clarify the pathogenesis and treatment mechanism of the disease.
Methods: In this study, thirty 2-month-old mice were selected for operation to establish a coccygeal IDD model.

Background: Painful degeneration of the sternoclavicular joint refractory to nonoperative treatment has historically been managed with resection of the degenerative segment of the medial clavicle. Although this has produced good results with improvement in symptoms, recurrent pain necessitating revision surgery is not an infrequently encountered outcome. To reduce the occurrence of recurrent postoperative pain, a novel technique to reconstruct the intra-articular disc at the time of medial clavicle resection was developed.

Background: There are differences in the extent of excision of articular processes, spinal processes and posterior ligamentum complexes (PLC) for posterior approach lumbar interbody fusion. Given that the biomechanical significance of these structures has been verified and that deterioration of the biomechanical environment is the main trigger for complications in both fused and adjacent motion segments, changes in decompression ranges may affect the potential risk of adjacent segmental disease (ASD) biomechanically; however, this topic has yet to be identified.
Methods: Posterior lumbar interbody fusion (PLIF) with different decompression strategies was simulated in a well-validated lumbosacral model.

Background: For L5/S1 extraforaminal disc herniation, how to efficiently expose the herniated nucleus pulposus and reduce facet joint damage remain to be explored.
Methods: Lumbar discectomy was performed using a full-endoscopic transsacral approach, in which sacral ala and extraforaminal ligament were partially resected to expose the L5/S1 intervertebral disc. Methylene blue was used for disc staining, and the herniated nucleus pulposus was excised through the annular tear.

Background: Vertebral fractures in young populations are associated with intervertebral disc disorders later in life. However, damage to the annulus fibrosus has been observed in rapidly loaded spines even without the subsequent occurrence of a fracture. Therefore, it may not be the fracture event that compromises the disc, but rather the manner in which the disc is loaded.
