In such cases, a complete replacement can seldom be performed of inflammation and/or an infection of the surrounding tissue. A secondary reconstruction should be performed after both local inflammation and infec-tion have been controlled.  We herein report a patient who had undergone a previous gastrectomy in whom a successful second re-construction of the thoracic esophagus was performed using a free jejunal graft, after the initial failure of the right coloplasty using the presternal route.Address Correspondence : Ryuichiro Suto, M.D. Department of Surgery II , Nagasaki University School of Medicine, 1-7-1 Sakamoto, Nagasaki City, Nagasaki 852-8501, Japan TEL: +81-95-849-7316, FAX: +81-95-849-7319Case Report  A 58-year-old Japanese man was referred to our hos-pital with a diagnosis of esophageal cancer. His medi-cal history included a distal partial gastrectomy for early cancer at the age of 46. On admission, no evi-dence of cervical lymphadenopathy was observed. The laboratory data were as follows: red blood cells, 435 X 104/ml; white blood cells, 7500/ml; hemoglobin, 11.8 g/dl; hematocrit, 36.2%; and platelet count, 40.6 X 10' /ml. The serum chemistry findings showed no remark-able abnormalities. The tumor markers in the serum, including squamous cell carcinoma related antigen (SCC ), carcinoembryonic antigen (CEA ), and carbohy-drate antigen 19-9 (CA 19-9) , were all within the normal limits.  Esophagography revealed a tumor which measured 7cm in size at the mid-thoracic portion of the esopha-gus, and endoscopy demonstrated an ulcerated tumor with an irregular border which occupied half of the entire esophageal wall (Fig.1). A biopsy specimen taken from the tumor was histologically proven to be squamous cell carcinoma. Computed tomography (CT) of the neck, chest and abdomen showed the thoracic esophageal wall to be thicker than normal and no evidence of in-vasion to the adjacent organs or any distant metasta-sis. As a result, the patient was considered to be a can-didate for surgery.  On August 24, 1998, a subtotal esophagectomy with a regional lymph node dissection and thoracic eso-phageal reconstruction using the pedicled right colon was performed by the presternal route. There was no evidence of invasion of any neighboring organs. The tumor in the resected specimen measured 6.5 X 2.5 cm in size (Fig.2). A histological examination revealed poorly differentiated squamous cell carcinoma with evidence of lymph node metastasis. On the 7th postoperative day, the cervical end of the colon used for reconstruction was found to be necrotic due to dirty discharge and,therefore, a resection of the necrotic area (7cm) together with an esophagostomy plus colostomy were performed. The cephalic end of the colostomy was exteriorized in the midline 7cm from the supra sternal notch. On the 36th postoperative day, an esophageal reconstruction using a free jejunal graft was attempted. A 20 cm-long segment of the jejunum was simultaneously harvested based on the second jejunal vascular system. The ves-sels of the grafted jejunum were anastomosed to the right superior thyroidal artery and the internal jugular vein, respectively, under a microscope (Fig.3). The pa-tient's postoperative course was uneventful and he was discharged on the 130th postoperative day after the ini-tial surgery, tolerating a normal diet but experiencing a feeling of slight regurgitation. (Fig.4).Fig.2. The resected specimen showed a Borrmann type 2 tumor in the middle thoracic esophagus.Fig.l. A barium esophagogram revealed a tumor in the middle thoracic esophagus.Fig.3. A free jejunal graft was transplanted between the cervical esophagus and colic pedicle and the vessels of which were anastomosed to the right superior thyroidal artery and internal jugular vein.Fig.4. Barium was observed to pass swiftly into the colic pedicle through the transplanted jejunum on the 42th postoperative day.Discussion   Owing to the recent advances in the treatment of esophageal cancer, the number of perioperative compli-cations and the rates of morbidity have been decreasing. However, hospital mortality is high when patients de-velop necrosis in the organs used for reconstruction' 2>. These complications occur because of the potential for vascular insufficiency at the cervical end of the pulled-up gastric or colic pedicles. Although, these pedicles are usually well nourished, the blood circulation is occa-sionally compromised due to') tension on the pulled-up stomach or colon for a difficult reach,') a failure on the part of the operative maneuvers to sufficiently pre-serve the feeding vessels, and') the occurrence of nega-tive side-effects due to the operation itself. Insufficient blood circulation is a primary factor in the develop-ment of necrosis since the length and type of organ used as an esophageal substitute are important. After a total thoracic esophagectomy for esophageal cancer, the organs used for esophageal replacement include the stomach, isoperistaltic jejunum and the short seg-ment of the colon. The incidence of necrosis in the or-gans used for a reconstruction is only 1 % for the stom-ach, 11% for the jejunum and from 13-16% for the colon"'). In addition, the incidence of necrosis of the stomach used for reconstruction is 6 % for the subcuta-neous route, and 1 % for both the retrosternal and the posterior mediastinal routes. Therefore, the incidence of necrosis of the stomach used for reconstruction was 3 % for the presternal route while that of the colon was as high as 30 % ". This is probably because the sta-bility of blood supply to the colon is much less than that to the stomach, and also because the length of the presternal route is 3.7cm longer than that of the orthotopic routes).  The diagnosis of necrosis was easy to make based on direct observations of the color of the organs and a check for the odour specific to the necrotic organ immidiately after an incision of the skin. If the area of necrosis in an organ used for reconstriction is partial, then conservative treatment may sometimes be possi-ble; however, surgical treatment, consisting of a resec-tion of the necrotic area plus an esophagostomy and gastrostomy/colostomy, are usually required.  In our case, the restoration of esophageal continuity was achieved by a free jejunal transfer, since it is a popular and reliable method for a reconstruction of the pharynx and cervical esophagus". A free jejunal graft seems to provide the ideal material for reconstruction because it allows for the tension-free anastomosis of a well-vascularized intestine.  Patients with presternal colonic reconstructions arehighly selected for several reasons and should thus be considered as high risk candidates for postoperative necrosis of the colon. When necrosis of the organs used for reconstruction is observed, then early drainage and a secondary reconstruction using a free jejunal graft should result in a favorable outcome.References 1) H.
