Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

2024
Carpal tunnel decompression with transverse carpal ligament transection is a very successful treatment of carpal tunnel syndrome. The standard long-curved incision technique has become the best treatment for median nerve entrapment decompression. Here we introduce the metacarpal small incision carpal tunnel release (MSICTR) in the treatment of carpal tunnel syndrome (CTS).

Surgical Robot-Assisted Transanal Specimen Extraction Radical Sigmoidectomy Without an Auxiliary Abdominal Incision

2025
Robot-assisted natural orifice specimen extraction surgery is a minimally invasive technique that combines robotic precision with natural orifice specimen extraction. A 67-year-old patient successfully underwent the procedure in 290 min, with minimal bleeding and no residual cancer. This approach minimized abdominal trauma, reduced complications, and enabled a quick recovery.
FAQs
Alignment with the long axis of a body region or anatomical structure helps create a predictable path toward underlying tissues. This orientation supports controlled access and sustained exposure during a procedure, which can be important when surgeons need to remove a tumor, obtain a biopsy, implant material, or collect tissue in a consistent manner.
Consistent placement helps researchers distinguish effects caused by the experimental intervention from variation introduced by the surgical approach. When longitudinal incisions are positioned and closed according to a standardized plan, studies can more reliably evaluate tumor biology, treatment effects, surgical outcomes, and postoperative recovery across experimental models or clinical procedures.
Closure restores the separated skin and deeper tissue layers after the required exposure has been completed. In cancer research, using a consistent closure approach supports evaluation of tissue healing and postoperative recovery, while also making surgical outcomes more comparable between procedures. Closure therefore forms part of the experimental design, not merely the final procedural step.
The approach can provide access for several cancer-related activities, including tumor excision, biopsy, implantation, and tissue collection. Its value depends on the procedure being performed and the anatomical region involved. In experimental models and clinical procedures, the incision creates the working access needed to perform the intervention and assess its consequences afterward.
The workflow includes creating the lengthwise cut, separating the skin and deeper layers, maintaining exposure for the planned intervention, and closing the wound afterward. Depending on the study, the exposed area may support tumor removal, sampling, implantation, or tissue collection. Keeping these stages consistent helps researchers compare outcomes across procedures.
Researchers may use a longitudinal incision when an experimental procedure requires access to underlying tissues for tumor excision, biopsy, implantation, or tissue collection. The approach is relevant when the study must connect a defined surgical intervention with later observations of tumor biology, treatment effects, surgical outcomes, or postoperative recovery.
Standardization allows investigators to examine several outcome categories together: how the tumor behaves, how a treatment affects the tissue or tumor, how the surgical procedure performs, and how recovery progresses afterward. Recording incision placement and closure consistently strengthens comparisons among experimental groups and helps separate procedure-related variation from treatment-related effects.
