Situs inversus totalis (SIT) is a rare congenital autosomal recessive hereditary disease characterized by complete inversion of the thoracic and abdominal viscera. As a result, surgical procedures are considered more difficult in patients with SIT owing to the mirrored image of the anatomy, especially in laparoscopic surgery. Herein, we report a case of SIT in a patient diagnosed with sigmoid colon cancer, that was treated with single-incision plus one-port laparoscopic sigmoidectomy. The patient was discharged on post-operative day 5 without any complication. Single-incision plus one-port laparoscopic anterior resection for SIT patient with colorectal cancer is safe and feasible when performed by a skilled surgeon with fully understanding of the anatomy.
完全性器官逆位是一種少見的自體隱性遺傳疾病,胸腔及腹腔內的器官完全左右相反,呈現鏡像的表現。因此在臨床上疾病診斷及外科手術上伴隨相當程度的困難,尤其是在微創的腹腔鏡手術方面由是如此。我們在此分享一位五十七歲男性,因排便習慣改變及血便等徵象求診,進一步大腸鏡檢查則發現乙狀結腸處一巨大腫瘤,切片檢查顯示為腺癌。在經過後續單切口外加一孔之腹腔鏡乙狀結腸切除,術後逐漸恢復正常活動及進食。臨床上無特殊併發症,於術後五天順利出院。以這樣的病例而言,手術上困難的不只是單孔腹腔鏡手術空間上的限制,病人本身肥胖體型也對手術的時間存在影響。不過,在此我們認為,完全性器官逆轉位患者在接受手術上,經由完整術前評估及仔細影像上的規劃,由有經驗的外科醫師執行腹腔鏡手術是相對安全且適合的治療方式。
