Although skin grafts and nasolabial flaps are reliable, they can cause secondary post-surgical deformities.Methods: In this report, we describe an alar spiral advancement flap with a subcutaneous pedicle combined with postoperative nasal stent therapy for the repair of alar defects.Results: All cases showed slight asymmetry immediately after surgery, but at a median follow-up of 24 months, no cases of dissatisfaction with the nose shape or abnormal respiratory function were found. Almost all incision scars subsided within 12 months. In addition, all flaps that were dissected and rotated during the surgeries healed, and no signs of necrosis or development of vascular compromise were observed.Conclusion: Our preliminary experience suggests that the alar spiral flap followed by nasal stent therapy provides stable recovery of appearance and function for alar defects during follow-ups and shows promise for future therapies.展开更多

Although a bridge to surgery can be created to obviate the need for emergency surgery, its effects on long-term outcomes and the most practical management strategies for right-sided malignant colonic obstruction remain unclear.AIM To determine the appropriate management approach for right-sided malignant colonic obstruction.METHODS Forty patients with right-sided malignant colonic obstruction who underwent curative resection from January 2007 to April 2017 were included in the study.We compared the perioperative and long-term outcomes of patients who received bridges to surgery established using decompression tubes and those created using self-expandable metallic stents(SEMS). The primary outcome was the overall survival duration(OS) and the secondary endpoints were the diseasefree survival(DFS) duration and the preoperative and postoperative morbidity rates. Analysis was performed on an intention-to-treat basis.RESULTS There were 21 patients in the decompression tube group and 19 in the SEMS group. There were no significant differences in the perioperative morbidity rates of the two groups. The OS rate was significantly higher in the decompression tube group than in the SEMS group(5-year OS rate; decompression tube 79.5%,SEMS 32%, P = 0.043). Multivariate analysis revealed that the bridge to surgery using a decompression tube was significantly associated with the OS(hazard ratio, 17.41; P = 0.004). The 3-year DFS rate was significantly higher in thedecompression tube group than in the SEMS group(68.9% vs 45.9%; log-rank test,P = 0.032). A propensity score–adjusted analysis also demonstrated that the prognosis was significantly better in the decompression tube group than in the SEMS group.CONCLUSION The bridge to surgery using trans-nasal and trans-anal decompression tubes for right-sided malignant colonic obstruction is safe and may improve long-term outcomes.展开更多
