AI Article Synopsis
- The enteric nervous system (ENS) is key for controlling digestive functions like muscle movement and nutrient uptake, and studying its nerve plexus can help understand disorders related to it.
- A new, easier method for preparing whole mounts of the longitudinal muscle and myenteric plexuses (LMMPs) in rat colon is presented, which simplifies the extraction process using basic tools like glass rods and cotton swabs.
- This method significantly improves upon existing techniques by allowing faster preparation of high-quality LMMPs, facilitating better observation and research on the ENS's structure and function.
Article Abstract
Background: The nerve plexus of the enteric nervous system (ENS) plays a crucial part in regulating gastrointestinal functions, such as muscle contractile activity and nutrient absorption. Studying the nerve plexus can provide vital information for research on ENS disorders. Whole-mount preparation is an important technique for investigating the nerve plexus. However, currently available methods are time consuming and highly technical.
New Method: This study describes a simple and rapid method for preparing whole mounts of the longitudinal muscle and myenteric plexuses (LMMPs) of rat colon. Integral LMMPs can be easily separated from the underlying layer by using glass rods and wet cotton swabs.
Results: The proposed method allows the easy separation of the LMMPs in intact sheets. Immunofluorescence histochemical staining of whole mounts enable clear visualization of enteric ganglia, nerve fibers, and several subtypes of neuronal populations residing in the myenteric plexus.
Comparison With Existing Methods: Compared with existing procedures for whole-mount preparations, the proposed method achieves a quicker and more efficient preparation of high-quality LMMPs from intestinal segments in sufficient quantity.
Conclusions: This work provides a rapid method for efficiently preparing whole mounts of the intestines. Our method can be used for in situ observation of the morphological and functional alterations of the myenteric plexus for further studies on the ENS.

Successful management of interdural spinal cysts presenting as radiculopathy caused by epidural venous enlargement: illustrative case.
J Neurosurg Case Lessons

Division of Neurosurgery, Tohoku Medical and Pharmaceutical University, Sendai, Japan.
Background: The authors report the first case of thoracic interdural spinal cysts presenting as radiculopathy attributed to overdrainage-related cervical venous plexus enlargement. This case emphasizes the importance of considering interdural spinal cysts and cerebrospinal fluid overdrainage in the differential diagnosis of radiculopathy.
Observations: A 37-year-old male patient with a history of orthostatic headache presented with bilateral deltoid muscle atrophy consistent with C5 radiculopathy.
Obstetric Outcomes by Hospital Volume of Operative Vaginal Delivery.

Article Synopsis
- This study examined how the volume of operative vaginal deliveries (OVDs) at hospitals in California from 2008 to 2020 affects adverse outcomes for both birthing individuals and newborns.
- It categorized hospital OVD volume into low (less than 5.2%), medium (5.2%-7.4%), and high (7.4% or more), finding that lower volume hospitals had a higher incidence of complications such as obstetric anal sphincter injuries and adverse neonatal outcomes.
- The research utilized extensive data from birth certificates and hospital records to analyze trends, highlighting the need for improvements in obstetric care based on hospital performance.
Robotic right-sided colon cancer surgery: Dissecting the outermost layer of the autonomic nerve along the superior mesenteric artery.
Ann Gastroenterol Surg

Division of Frontier Surgery, The Institute of Medical Science The University of Tokyo Bunkyō Japan.
In right-sided colon cancer surgery, lymph node dissection around the superior mesenteric artery is necessary but technically challenging. Here we introduce the concept of "outermost layer-oriented robotic surgery" to improve the safety, efficacy, and reproducibility of superior mesenteric artery nodal dissection. In this procedure, the thin, loose connective tissue layer between the autonomic nerve sheath of the superior mesenteric artery and adipose tissue bearing lymph nodes, termed "the outermost layer of the autonomic nerve," is dissected.

Background: Because of the limitations of pharmacological therapy, nonpharmacological therapies including intervention procedures are also important for quality of cancer pain management.
Objective: To clarify the availability of, number performed, barriers to performing, and educational practices of four interventional procedures (celiac plexus neurolysis/splanchnic nerve neurolysis, phenol saddle block, epidural analgesia, and intrathecal analgesia) in designated cancer hospitals.
Design: Cross-sectional survey.
