Summary
Transanal Minimally Invasive Surgery (TAMIS) is safe and effective for rectal lesions in regional hospitals. This technique offers good outcomes for various conditions with acceptable complication rates.
Area of Science:
- Colorectal Surgery
- Minimally Invasive Surgery
- Surgical Oncology
Background:
- Transanal Minimally Invasive Surgery (TAMIS) offers advantages over traditional rectal lesion excision.
- Most TAMIS data come from tertiary centers, limiting understanding of its use in regional settings.
Purpose of the Study:
- To evaluate the outcomes of TAMIS performed at a regional New Zealand hospital.
- To assess the safety and efficacy of TAMIS for diverse rectal pathologies in a non-tertiary setting.
Main Methods:
- Retrospective analysis of 65 patients undergoing TAMIS at Tauranga Hospital (Dec 2014 - Oct 2025).
- Data collected included demographics, operative details, histopathology, morbidity, and 30-day mortality.
- Complications were classified using the Clavien-Dindo system.
Main Results:
- Successful R0 resection achieved in 97% of polyps and 85% of adenocarcinomas.
- Mean length of stay was 1.5 days; 11% experienced Clavien-Dindo grade II complications and 6% grade III.
- One postoperative mortality (1.6%); no adenocarcinoma recurrence observed.
Conclusions:
- TAMIS is a safe and effective procedure for regional centers.
- It provides acceptable morbidity and mortality rates for treating a broad spectrum of rectal pathologies.

01:03IR Frequency Region: Fingerprint Region
1.9K
IR spectra are divided into two main regions: the diagnostic region and the fingerprint region. The diagnostic region of the spectrum lies above 1500 cm−1. The absorptions resulting from single-bond vibrations of the N–H, C–H, and O–H stretch at higher wavenumbers and appear on the left side of the spectrum. The stretching absorptions of the C≡C and C≡N occur between 2100–2300 cm−1. In contrast, those arising from stretching absorptions of the...

02:40The Eukaryotic Promoter Region
18.7K
The eukaryotic promoter region is a segment of DNA located upstream of a gene. It contains an RNA polymerase binding site, a transcription start site, and several cis-regulatory sequences. The proximal promoter region is located in the vicinity of the gene and has cis-regulatory sequences and the core promoter. The core promoter is the binding site for RNA polymerase and is usually located between -35 and +35 nucleotides from the transcription start site. The distal promoter regions are...

17.4K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

01:17Region of Convergence
894
The z-transform is a powerful mathematical tool used in the analysis of discrete-time signals and systems. It is a crucial tool in the analysis of discrete-time systems, but its convergence is limited to specific values of the complex variable z. This range of values, known as the Region of Convergence (ROC), is fundamental in determining the behavior and stability of a system or signal. The ROC defines the region in the complex plane where the z-transform converges, which can take various...

Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

6.6K
In a beam of charged particles created by a heated cathode, the particles move at different speeds. However, many applications need a beam with uniform particle speeds. An arrangement known as a velocity selector uses electric and magnetic fields to pick particles with a particular speed from the beam.
A particle with charge q, speed v, and mass m enters an area from the top, where the magnetic and electric fields are perpendicular both to the particle's motion and to one another. The magnetic...
