Necrosis of a reconstructed organ after esophagectomy is a rare postoperative complication. However, in case this complication develops, severe infectious complications can occur, and subsequent surgical reconstruction is quite complicated. To treat esophageal conduit necrosis after esophageal reconstruction with the terminal ileum and ascending colon, we reconstructed the esophagus using a transverse colon, which was covered with a pectoralis major muscle flap to reinforce the anastomotic site. In addition, split thickness skin grafts were applied to the wide skin defect to cover the reconstructed organs at the antesternal route. Widely extended split thickness skin grafts can adhere to the reconstructed organs without excessive tension. Therefore, this method enabled successful treatment of an esophageal defect and wide skin defects of the anterior chest wall.

In adult cases of bilateral cleft lip nasal deformity, an esthetically satisfying result can not be obtained only by manipulation inside the nose with the nasal tip pointing upward. The nasal tip should be made in a more anterior direction for nasal esthetic improvement. Additional tissue beyond the nose is needed, and the forked flap is a useful method in such cases. However, the blood circulation of long and narrow flaps containing the scar, especially after open rhinoplasty, is unstable. We have developed a new long and narrow forked flap that has a more stable blood circulation. The forked flap was made using two subcutaneous pedicles attached to the periphery of the each flap. We applied this flap to five adult cases of bilateral cleft lip nasal deformity. Four of the cases had the scar associated with the flying bird incision, and one case required no treatment after the primary repair. All the flaps took without signs of partial necrosis. In all cases, the nasal tip was projected forward with adequate columella elongation, and the profile was esthetically improved. In the final stage of correction for adult cases of bilateral cleft lip nasal deformity, this method, making maximum use of the tissue containing the scar in not only the white lip but also the vermilion, is very effective. It is very important to obtain nasal esthetic improvement for the adult patient with bilateral cleft lip nasal deformity.

Intra-wound continuous negative pressure irrigation treatment (IW-CONPIT) was administered to cases of mediastinitis as the therapy of choice, with satisfactory results being obtained in terms of improved survival rates and quick healing of wounds. Accordingly, these treatment results and efficacy were evaluated. After debridement, a sponge was trimmed to conform to the shape of the wound and then it was attached to the surface of the wound. Two tubes with several side holes were placed within the sponge. In cases in which the blood vessels and/or the heart are exposed, an artificial dermis was attached to cover the blood vessels and/or the heart in order to not come in direct contact with the sponge. Next, the top of the wound was covered with polyethylene film to create an air-tight wound seal. A bottle of saline solution was connected to one of the tubes and a continuous aspirator to the other, and continuous negative pressure irrigation of the wound was thus carried out. After performing this treatment for 2-3 weeks, and when wound granulation improved, either skin grafts or the transplantation of muscle flaps was performed as necessary to achieve wound healing. A combination of the continuous negative pressure method and the continuous irrigation method resulted in improved healing rates and lower mortality rates for mediastinitis. It also significantly reduced the number of dressings, as well as the degree of labour and medical materials required; therefore, a reduced hospital stay and shorter treatment period was thus achieved using this treatment method.

Central venous stenosis has emerged as a significant clinical problem in hemodialysis patients. Endovascular interventions, including percutaneous transluminal angioplasty (PTA), have gained popularity for the initial treatment of venous hypertension due to central venous lesions. The purpose of our study was to evaluate the efficacy of PTA for the treatment of central venous stenosis or occlusion in patients undergoing hemodialysis. We retrospectively identified 17 hemodialysis patients (9 men and 8 women with a mean age of 64 years) who had central venous lesions treated by PTA. The lesions involved the axillary, subclavian, and innominate veins with complete occlusion in 3 cases. The procedure of PTA was a technical success without complications in all cases.The mean follow-up was 23 months (range, 1-67 months). The cumulative primary patency rates were 85.7%, 78.6%, 44.2%, and 33.1% at 6, 12, 24, and 36 months, respectively. The cumulative secondary patency rates were 100% at 6 and 12 months, and 90.9%, 77.9% at 24 and 36 months.In conclusion, percutaneous central venous angioplasty can provide symptomatic relief and restore the functionality of the vascular access in hemodialysis patients. Although multiple procedures are often required, PTA would be a first-line approach in this condition, in terms of its safety and minimal invasiveness.

Summary: Large enterocutaneous fistulas of the small intestine are rare and difficult to close, particularly if the fistula is associated with massive leakage of digestive juice and the residual intestinal tract is too short for anastomosis. We present a patient who underwent small bowel resection and secondary anastomosis following massive necrosis of the small intestine due to superior mesenteric artery thrombosis. After resection of an enterocutaneous fistula and reanastomosis, the residual small bowel was only 70 cm long with a persistent fistula. We successfully closed the fistula by employing a hinged rectus abdominis musculocutaneous flap. Here, we report our procedure for treating a large enterocutaneous fistula without performing laparotomy and bowel resection.
