Intestinal obstruction remains a major cause of morbidity and mortality in surgical patients. We reviewed the records of 77 patients with mechanical small-bowel obstruction who were treated with endoscopically and fluoroscopically placed Leonard long intestinal tube decompression. Most patients (59%) had failed a trial of nasogastric tube or Miller-Abbott tube decompression. Overall, 29 per cent of patients were able to resolve their obstruction with Leonard tube decompression alone. Subdivision of patients on the basis of the etiology of their obstruction demonstrated a much higher rate of success for tube decompression in adhesive obstruction (37%) versus malignant obstruction (12%) or inflammatory obstruction (no successes). Patients with radiographic and clinical evidence of complete intestinal obstruction were significantly less likely to respond to long intestinal tube treatment (13%). The long intestinal tube was easily passed in all patients. There were no complications of the intubation procedure in our series, and the incidence of tube-related complications was four per cent. We conclude that an initial period of long intestinal tube decompression allows a significant percentage of patients with mechanical small-bowel obstruction to be treated nonoperatively, particularly if a partial obstruction from postoperative adhesions is present. Patients who have failed a trial of nasogastric tube decompression and are poor operative risks should also be considered for long intestinal tube placement.
肠梗阻仍然是外科手术患者发病和死亡的主要原因。我们回顾了77例机械性小肠梗阻患者的记录,这些患者接受了经内镜和荧光镜放置的伦纳德长肠管减压治疗。大多数患者(59%)经鼻胃管或米勒-雅培管减压治疗失败。总体而言,29%的患者仅通过伦纳德管减压就能解除梗阻。根据梗阻病因对患者进行细分后发现,粘连性梗阻患者通过肠管减压成功的比例(37%)远高于恶性梗阻(12%)或炎性梗阻(无一例成功)。有影像学和临床证据表明完全性肠梗阻的患者对长肠管治疗有反应的可能性显著降低(13%)。长肠管在所有患者中都很容易通过。我们的系列研究中插管过程无并发症,与肠管相关的并发症发生率为4%。我们得出结论,初始阶段的长肠管减压可使相当比例的机械性小肠梗阻患者接受非手术治疗,尤其是存在术后粘连导致的部分性梗阻时。经鼻胃管减压治疗失败且手术风险高的患者也应考虑放置长肠管。
