目的探讨阑尾黏液囊肿及腹膜假性黏液瘤的诊断和治疗方法.方法#例阑尾黏液囊肿患者,行单纯阑尾切除术>例；行回盲部切除$例；行右半结肠切除术!例； !例急诊行阑尾切除术后,再次行右半结肠切除术； !例术中发现阑尾囊肿破裂合并腹膜假性黏液瘤,行右半结肠切除术,吸净腹腔内腹水,生理盐水冲洗腹腔,术后全身化疗!次.结果所有患者均手术成功,无明显手术并发症.经随访,均无复发.结论本病临床不多见,但以右下腹痛及包块为主诉的患者应警惕本病.?型超声检查及消化道造影可能是较为简便经济的诊断方法.严格掌握手术适应证,对疑有本病的患者认真探查腹腔会得到最佳的治疗效果.对腹膜假性黏液瘤患者术后化疗或放射治疗可取得较好的疗效. Objective To investigate the diagnosis and treatment of appendicular mucinous cysts and peritoneal pseudomyxomas.Methods #Patients with appendiceal mucinous cysts were treated with simple appendectomy.Effective ileocecal resection was performed in $cases. Right colon resection was performed. After emergency appendectomy, right hemicolectomy was performed again. During the operation, a ruptured appendix cyst was found with a pseudomyxoma of the peritoneum. Right colon resection was performed. Ascites were aspirated intraperitoneally and saline was used to flush the abdominal cavity. Systemic chemotherapy after surgery! times. Results All patients were successfully operated without obvious surgical complications. After follow-up, there was no recurrence. Conclusion The disease is rare in clinical practice, but patients with primary right lower abdominal pain and masses should be vigilant Disease-type ultrasonography and gastrointestinal angiography may be a more convenient and economical diagnostic method. Strict control of surgical indications, and careful exploration of the abdominal cavity in patients suspected of this disease will get the best therapeutic effect. Patients with peritoneal pseudomyxoma Postoperative chemotherapy or radiation therapy can achieve better results.
