Blind loop syndrome is a malabsorptive condition resulting from intestinal stasis, which promotes bacterial overgrowth and leads to various gastrointestinal and systemic manifestations. It often occurs secondary to anatomical or motility abnormalities, particularly after gastrointestinal surgeries. We present the case of a 75-year-old male with a history of colon cancer status post right hemicolectomy with ileo-colonic anastomosis, who was incidentally found to have severe iron deficiency anaemia during a routine check-up. One year prior, follow-up endoscopies were normal. However, recent investigations revealed a hyperplastic polyp in the gastric cardia and, more importantly, a blind loop with ulcerations distal to the ileum on colonoscopy. Biopsies confirmed ulcerated ileal/colonic mucosa with granulation tissue. The patient underwent surgical resection of the blind loop with the creation of an ileo-transverse anastomosis. Postoperatively, he recovered well and was discharged on a regular diet. This case illustrates the importance of considering blind loop syndrome in patients with a history of bowel surgery who present with non-specific symptoms such as anaemia. It also highlights the potential for delayed onset and the diagnostic value of endoscopy when routine workups are inconclusive. Surgical correction remains the definitive treatment in anatomically driven cases, offering significant symptomatic relief and prevention of further complications.
Blind loop syndrome should be suspected in patients with prior bowel surgeries.It can present as anaemia.It may present years after surgery.It may be more common than statistics suggest, as it is often underdiagnosed or misdiagnosed.
盲袢综合征是一种由肠道淤滞导致的吸收不良状况，肠道淤滞会促使细菌过度生长并引发各种胃肠道和全身表现。它常继发于解剖结构或动力异常，尤其是在胃肠道手术后。我们报告一例75岁男性病例，该患者有结肠癌病史，接受了右半结肠切除术并进行回肠 - 结肠吻合术，在一次常规体检中偶然发现患有严重缺铁性贫血。一年前，随访内镜检查结果正常。然而，近期检查发现胃贲门有一个增生性息肉，更重要的是，结肠镜检查发现回肠远端有一个伴有溃疡的盲袢。活检证实回肠/结肠黏膜溃疡伴肉芽组织形成。患者接受了盲袢手术切除并进行回肠 - 横结肠吻合术。术后，他恢复良好并恢复正常饮食出院。该病例说明了对于有肠道手术史且出现贫血等非特异性症状的患者，考虑盲袢综合征的重要性。它还强调了发病延迟的可能性以及当常规检查结果不明确时内镜检查的诊断价值。对于由解剖结构异常引起的病例，手术矫正仍然是 definitive 治疗方法，能显著缓解症状并预防进一步并发症。
有肠道手术史的患者应怀疑患有盲袢综合征。它可能表现为贫血。它可能在手术后数年出现。它可能比统计数据显示的更常见，因为它常被漏诊或误诊。
“definitive”此处结合语境推测意思为“决定性的、最终的”，但在医学领域可能有更准确的专业释义，因未明确要求进一步解释，故保留英文单词。
