内镜黏膜下剥离术后食管狭窄的发生机制、预防及治疗

内镜黏膜下剥离术（endoscopic submucosal dissection,ESD）已经成为早期食管癌，尤其是大面积早期食管癌的主要治疗方法。早期食管癌可以通过ESD完全治愈，但是对于大面积早期食管癌，尤其是超过3/4周病变甚至全周病变的患者，ESD术后发生食管狭窄的概率明显升高，患者出现吞咽困难，给患者带来新的痛苦及沉重的经济负担，下面对早期食管癌ESD术后食管狭窄的发生机制、预防及治疗作一综述。

Comparison of clinical outcomes of deep anterior lamellar keratoplasty and excimer laser assisted anterior lamellar keratoplasty in keratoconus

AIM: To compare and evaluate the clinical outcomes of deep anterior lamellar keratoplasty (DALK) and excimer laser assisted anterior lamellar keratoplasty (ELLK) in eyes with keratoconus. METHODS: In this study, 57 eyes of 56 patients operated between 2013 to 2017 were included. Thirty-one eyes underwent big-bubble DALK and twenty-six eyes underwent ELLK. Preoperative and at control visits complete ophthalmic examination was performed. RESULTS: The mean patient age at the time of DALK surgery was 27y and mean follow-up period was 21±5.4mo. The mean patient age at the time of ELLK surgery was 27y and mean follow-up period was 40±18mo. Mean best spectacle corrected visual acuity (BSCVA) at postoperative period was significantly higher for DALK group (0.66±0.11) versus ELLK group (0.4±0.2) (P<0.05). Descemet’s membrane microperforation was occurred in 7 patients in DALK group versus in 1 patient in ELLK group. In 4 eyes, interface irregularity was developed in ELLK group. None of the patients in follow-up had graft rejection in both groups. CONCLUSION: In ELLK group, complication rate is lower, the surgical technique is simpler, faster and safer and also ELLK requires less experience with respect to DALK. Further, DALK can be performed unless satisfactory visual acuity is achieved after ELLK.
