Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Endoscopic Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

腫瘍学における外科革新
医療イメージングにおける人工知能
最低侵襲手術のテクニック

背景:

ガストロコリック・トランクからの手術中の出血は,腹腔鏡による右側結腸切除の際に重大なリスクである.
手術の合併症を防ぐには胃腸の幹を正確に特定することが不可欠です

研究の目的:

手術ビデオで胃腸の幹を自動的に認識するためのディープラーニングモデルを開発し評価する.
腹腔鏡による右半球切除手術の安全性を向上させるため,リアルタイムで解剖学的識別を行う.

主な方法:

腹腔鏡による右側小腸切除のビデオからアノテーションされた静止画像を用いてディープラーニングモデルを開発した.
このモデルは,胃腸幹と上半腸静脈を区別するためのセグメンテーションタスクを実行した.
日本の10の病院の43人の患者のデータを5倍クロス検証で分析した.

主要な成果:

ディープラーニングモデルは,静脈セグメンテーション (タスクA) の平均ダイス係数0.84を達成しました.
ガストロコリック幹のセグメンテーションにより,平均ダイス係数は0.61 (タスクB) と0.58 (タスクC) であった.

結論:

腹腔鏡による右側小腸切除手術中に胃腸の幹を特定し視覚化するためのディープラーニングモデルが開発されました.
この技術は手術の安全性を向上させ術内出血のリスクを軽減する見込みです
このモデルの有効性を現実の手術環境で確認するには,さらなる臨床検証が必要である.
