- 结肠直肠手术 结肠直肠手术
背景情况:
- 胃口出口阻塞是治疗性结肠炎 (UC) 的整体直肠切除术与阴囊-门解剖 (IPAA) 后的常见并发症,影响20%-40%的患者.
- 右下腹腔静脉形成可能会增加小肠扭曲和张力,可能导致IPAA后的阻塞.
- 假设左下腹腔静脉管的放置可以减轻这些风险.
研究的目的:
- 为了确定左侧静脉栓放置是否减少静脉栓出口阻塞的发病率与右侧放置相比,在接受UC IPAA的患者中.
- 评估静脉管横向性对术后结果的影响,包括住院和重新手术率.
主要方法:
- 一个单中心,开放标签,随机对照试验,涉及181名UC患者,接受IPAA与骨髓切除术.
- 患者被随机分配到左侧 (L组,n=91) 或右侧 (R组,n=90) 的结节形成.
- 主要结局是静脉口阻塞的发生率,次要结局包括住院时间和重新手术率.
主要成果:
- 在左侧组 (9.8%) 与右侧组 (31.1%;p=0.0004) 相比,静脉口阻塞的发生率明显较低.

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:

01:21Drugs for Treatment of Constipation-Predominant IBS
670
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...

Introduction
An ostomy is a surgical procedure that creates an artificial opening from the intestines to the outside of the body, allowing for the rerouting of effluent. This opening is known as a stoma. A stoma usually protrudes above the skin surface, appearing pink or red, moist, and round, and it lacks nerve sensations.
There are different types of ostomies, including colostomies, ileostomies, and urostomies:

01:29Drugs for Treatment of Ulcerative Colitis in IBD
416
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
