まとめ
プロバイオティクスは,代謝および減量手術 (MBS) の後の体重減少を有意に改善しません. このメタアナリシスでは,過剰な体重減少やBMIの減少に効果がないことが判明し,現在の証拠はMBS後の日常的な使用を支持していないことを示唆しています.
科学分野:
- 腹部 外科
- 肥満管理
- 微生物群の研究
背景:
- 代謝・減量手術 (MBS) は重度の肥満には有効ですが,体重回復は困難です.
- プロバイオティクスはMBS後の体重管理のための補助療法として検討されています.
- この文脈でのプロバイオティクスの有効性は依然として議論の余地があります.
研究 の 目的:
- MBS後の患者の体重管理に対するプロバイオティクスの効果を評価する.
- MBS後の体重減少のためのプロバイオティクスの現在の証拠を合成する.
- プロバイオティクスがEWL,BMI,BMIの減少に有意な効果をもたらすかどうかを判断する.
主な方法:
- MBS後の患者でプロバイオティクスをプラセボと比較したランダム化比較試験のメタ分析.
- 2025年4月10日まで パブ・メド・エンバース・スコパス・コクラン・ライブラリで検索しました
- 主要アウトカムに対するランダム効果モデルを用いたプールのデータ: %EWL,手術後のBMI,BMI減少.
主要な成果:
- 693人の患者を対象とした13件の試験を分析した.
- グループ間の%EWL (MD 0. 39,95%CI - 1. 90から2. 68) の有意な差はありません.
- 術後のBMI (MD 0. 07,95%CI - 0. 21から0. 35) やBMIの減少 (MD - 0. 05,95%CI - 0. 53から0. 44) は有意ではない.
- 手術の種類,プロバイオティック製剤,および持続時間によるサブグループ分析は有意な効果を示さなかった.
結論:
- 現在の証拠は,MBS後の体重減少を促進するためにプロバイオティクスの日常的な使用を支持していません.
- プロバイオティクスは外科的手法や治療期間に関係なく 治療結果を改善しないようです
- 標準化されたパラメータによるさらなる大規模試験が必要である.

Inflammatory Bowel Disease V: Surgical Management
212
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
419
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

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...

Obesity
612
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Drugs for Treatment of Constipation-Predominant IBS
331
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
