[Laparoscopic Left Hemicolectomy for Advanced Descending Colon Cancer in Patient with Idiopathic Pulmonary Arterial Hypertension-Report of a Case].

We experienced a case of laparoscopic left hemicolectomy for advanced descending colon cancer in patient with idiopathic pulmonary arterial hypertension(IPAH). The patient was a 39-year-old woman. She visited her family doctor in November 201X because of bowel movement disturbance and melena. She was diagnosed as advanced descending colon cancer. Although intraoperative management for hemodynamic stability was expected to be difficult due to IPAH, hemodynamic stability was achieved under 10 mmHg pneumoperitoneum. During the operation noradrenaline and phenylephrine were used for hemodynamic management. Laparoscopic left hemicolectomy was performed safely. Postoperative histopathological findings were as follows; Type 2, tub1>tub2, pT4a(SE), pN1a(1/65), int, INF b, ly1, v1, Pn1b, pPM0, pDM0, pStage Ⅲb(the Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma, 9th edition). The patient was discharged from the hospital on the 18th day after surgery without any complications except for Grade 2 diarrhea, which was considered a side effect of PGI2 preparation.
