研究目的:

探讨多模态超声检查(经会阴灰阶超声、经静脉超声造影、超声造影剂灌肠造影、经脓腔超声造影)对中低位直肠癌术后吻合口漏的诊断准确性。  

Objectives of Study:

To investigate the diagnostic accuracy of multimodal ultrasound (perineal ultrasound, intravenous contrast-enhanced ultrasound, ultrasound contrast agent enema, and transabscess contrast-enhanced ultrasound) for anastomotic leakage after mid-low rectal cancer surgery.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.肿瘤位于直肠中下段(肿物下缘距离肛缘<=10cm)并且手术病理证实为恶性; 2.直肠癌切除后采用结肠-直肠吻合、结肠-肛管吻合或直肠残端封闭; 3.直肠癌根治术后出院前、预防性造口回纳前(原发灶术后3个月或原发灶术后辅助治疗结束)、或患者出现不明原因的盆腔疼痛、发热或白细胞升高等情况,临床需排除吻合口漏(AL); 4.自愿签署知情同意书。

Inclusion criteria

1. The tumor is located in the middle and lower part of the rectum (the lower edge of the tumor is <= 10 cm from the anal verge) and the surgical pathology confirms it as malignant; 2. After rectal cancer resection, colo-rectal anastomosis, colo-anal anastomosis or closure of the rectal stump is adopted; 3. Before discharge after radical rectal cancer surgery, before preventive stoma reversal (3 months after the primary lesion surgery or after the completion of primary lesion surgery adjuvant therapy), or when the patient presents with unexplained pelvic pain, fever or elevated white blood cells, etc., clinically, the occurrence of anastomotic leakage (AL) needs to be excluded; 4. Voluntary signing of the informed consent form.

排除标准:

1.经腹会阴联合直肠切除术(Miles术); 2.拖出式直肠切除术(Bacon术); 3.对超声造影剂过敏; 4.直肠癌术后复发。

Exclusion criteria:

1. Abdominoperineal combined rectal resection (Miles procedure); 2. Pull-through rectal resection (Bacon procedure); 3. Allergic to ultrasound contrast agent; 4. Recurrence of rectal cancer after surgery.
