The Colonization of Land02:22

The Colonization of Land

37.7K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Marcia's Theory of Identity Status

1.7K
James Marcia's identity status model provides a framework for understanding how adolescents navigate identity formation through varying degrees of exploration and commitment. Marcia's model builds on Erik Erikson's theories of psychosocial development, focusing specifically on how adolescents reconcile individual aspirations with societal expectations. His model describes identity formation as a dynamic process where adolescents move between different states depending on their level...

Electrical Current01:10

Electrical Current

7.2K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

Current Density01:21

Current Density

5.2K
The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...

Eddy Currents01:25

Eddy Currents

2.7K
Since eddy currents occur only in conductors, magnets can separate metals from other materials. For example, in a recycling center, trash is dumped in batches down a ramp, beneath which lies a powerful magnet. Conductors in the trash are slowed by eddy currents, while nonmetals in the trash move on, separating from the metals. This works for all metals, not just ferromagnetic ones.
Other major applications of eddy currents appear in metal detectors and the braking systems of trains and roller...

Displacement Current01:19

Displacement Current

3.8K
Ampère's law, in its usual form, does not work in places where the current changes with time and is not steady. Thus, Maxwell suggested including an additional contribution, called the displacement current, Id, to the real conduction current I.

Summary
This summary is machine-generated.

Transrectal specimen extraction (TRSE) for laparoscopic colectomy is a feasible and safe minimally invasive surgical technique. While outcomes appear comparable to conventional laparoscopic colectomy, further high-quality trials are needed to confirm potential benefits in pain and hospital stay.

Area of Science:

  • Minimally Invasive Surgery
  • Colorectal Surgery
  • Surgical Innovation

Background:

  • Laparoscopic colectomy is a standard minimally invasive surgical approach.
  • Transrectal specimen extraction (TRSE) is an emerging technique for left-sided colectomy and upper rectum resection.
  • This review examines the current status and outcomes of TRSE.

Purpose of the Study:

  • To review the current status of left-sided colectomy and upper rectum resection using transrectal specimen extraction (TRSE).
  • To analyze surgical techniques, patient characteristics, and outcomes associated with TRSE.
  • To evaluate the feasibility, safety, and potential benefits of TRSE compared to conventional laparoscopic colectomy.

Main Methods:

  • Systematic review of publications on colorectal resection with natural orifice specimen extraction (NOSE).
  • Inclusion criteria focused on left colectomy, sigmoidectomy, and high anterior resection with transrectal specimen extraction (TRSE).
  • Exclusion of transanal, transvaginal, or transcolonic specimen extraction methods.

Main Results:

  • Thirty-five papers reported on TRSE, including randomized trials, case-matched series, and case reports.
  • Conversion rate to conventional laparoscopy was 3.7% (21/559) and overall morbidity was 9.5% (53/559).
  • No mortality was reported; postoperative anal incontinence was rare, with potential decreases in pain and hospital stay observed.

Conclusions:

  • Transrectal specimen extraction (TRSE) is a feasible and safe approach for selected patients undergoing colectomy.
  • Outcomes appear similar to conventional laparoscopic colectomy, with potential advantages in postoperative pain and length of hospital stay.
  • Lack of high-quality trials and inherent selection bias limit definitive conclusions.
