The Colonization of Land

The Colonization of Land

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...

Bonding in Metals

Bonding in Metals

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Metallic Solids

Metallic Solids

Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Esophageal Perforation-I: Introduction

Esophageal Perforation-I: Introduction

Esophageal perforation is a severe medical condition characterized by a breach in the integrity of the esophageal wall. This breach can occur due to various factors such as trauma, medical procedures, or underlying diseases. When the esophageal wall is compromised, it allows food, fluids, and digestive juices into the chest cavity or adjacent structures, leading to potential complications and health risks.
The location of esophageal perforation can vary, occurring anywhere along the esophagus....

Alkali Metals

Alkali Metals

Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

Metal-Ligand Bonds

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Summary

Self-expandable metallic stents offer effective treatment for colorectal strictures, but complications like perforation and fistula can occur. Careful patient selection and monitoring are crucial for safe and successful stent placement.

Area of Science:

Gastroenterology
Interventional Endoscopy
Colorectal Surgery

Background:

Self-expandable metallic stents (SEMS) are increasingly used for benign and malignant colorectal stenoses due to their efficacy and minimally invasive nature.
SEMS provide temporary relief in malignant colonic obstruction, facilitating transit and stabilizing patients for subsequent surgery.
In palliative care, SEMS can offer definitive treatment for obstruction, improving quality of life by avoiding colostomy.

Observation:

The study presents two emergency cases with complications arising from colonic endoprosthesis placement.
Case 1: A 56-year-old woman developed a decubitus perforation from a stent placed for metastatic rectal cancer.
Case 2: A 75-year-old man experienced a vescico-rectal fistula and re-occlusion after SEMS placement for a benign postoperative stricture.

Findings:

Colonic stent placement, while beneficial, carries risks of serious complications.
Perforation and fistula formation are significant adverse events associated with colorectal stenting.
These complications necessitate careful consideration of patient selection and post-procedure management.

Implications:

The findings highlight the importance of meticulous technique and patient selection in colorectal stenting procedures.
Further research may be needed to optimize stent design and deployment strategies to minimize complication rates.
These cases underscore the need for vigilance in monitoring patients post-stenting for early detection of adverse events.
