Urinary Tract Calculi VI: Surgical Management

283
Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.6K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.6K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Tumor Progression02:07

Tumor Progression

7.1K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Cancer Therapies

9.7K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Summary
This summary is machine-generated.

In 2019, new guidelines favor outpatient, antibiotic-free treatment for mild diverticulitis. Advanced imaging and minimally invasive surgery are increasingly vital for managing bowel obstructions and improving colon cancer outcomes.

Area of Science:

  • Colorectal Surgery
  • Oncologic Surgery
  • Gastroenterology

Background:

  • Acute diverticulitis and mechanical bowel obstruction are common diagnoses.
  • 2019 saw updated guidelines from EAES and SAGES for diverticulitis management.
  • Recent advancements impact the surgical and oncologic treatment of colorectal conditions.

Purpose of the Study:

  • To review novelties in colorectal and oncologic surgery from 2019.
  • To highlight updated management strategies for diverticulitis and bowel obstruction.
  • To discuss the role of neoadjuvant therapy in colon and rectal cancer.

Main Methods:

  • Review of 2019 European Association for Endoscopic Surgery (EAES) and Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) guidelines.
  • Analysis of recent multicentric studies on mechanical bowel obstruction.
  • Synthesis of published results on neoadjuvant treatment for colorectal cancer.

Main Results:

  • Current practice and data support ambulatory, antibiotic-free management for mild diverticulitis.
  • Imaging plays a crucial role in predicting surgical necessity and reducing delays in bowel obstruction.
  • Minimally invasive techniques are increasingly emphasized for mechanical bowel obstruction.
  • Latest findings on neoadjuvant treatment for colon and rectal cancer are presented.

Conclusions:

  • Updated guidelines and evidence support conservative management for mild diverticulitis.
  • Enhanced diagnostic imaging and minimally invasive approaches are transforming the care of mechanical bowel obstruction.
  • Neoadjuvant treatment strategies continue to evolve for colorectal cancer, improving patient outcomes.
