Objective To explore the effect and safety of the operationive treatment of calculus incarceration in neck of gallbladder.Methods We analyzed retrospectively the clinical data of 26 cases with calculus in carceration In neck of Gallbladder.Results All 26 cases patients were found to have serious cholecystitis and unclear anatomic site in Calot's trangle.Six patients'operative way had to transform from laparoscopiccholecystectomy to cholecystectomy.Endogenous membrane of gallbladder were excised retrogradely in the operation.In operative process,there were no injury in extrahepatic bile duct,intestinal canal and vascular.The all patients were recovery and discharge after operation.Conclusion It is one kind of good choice to open the gallbladder,aspirate the bile and extract the stones.And then performing endogenous membrane retrograde cholecystectomy.For treatment of the Calot's trangle areas,blunt dissection may used.It is dangerous that using sharp dissection and electrosurgical knife.

In February, 2019, a patient with a defect of open dorsal cartilage and bone in the first metatarsal head, including the defects of soft tissue, tendon and joint capsule, was treated in our department. After multiple debridement, the vascularised medial femoral condyle osteochondral chimeric tissue flap was transferred to repair the composite tissue defect in the metatarsal head at the second stage. After 18 months of follow-up, the patient felt no pain in the foot and walking, and there was no sign of lameness and discomfort at donor sites. The postoperative functional recovery was satisfactory.

AIM: To observe the changes of corneal densitometry(CD)and higher-order aberrations after small incision lenticule extraction(SMILE), and to explore their correlations and influencing factors.METHODS: Prospective study. A total of 62 high-degree myopia and compound myopic astigmatism patients(62 eyes)who underwent SMILE in Urumqi Aier Eye Hospital from December 2022 to November 2023 were collected. The CD, root mean square of corneal higher-order aberrations(RMS HOA), spherical aberration, vertical coma, horizontal coma, and corneal epithelial thickness(CET)of the patients were measured before surgery, and at 1 d, 1 wk, 1, 3, and 6 mo after surgery, respectively.RESULTS:There were 4 patients lost to follow-up during the period, all due to failure to attend scheduled reexaminations. The number of complete and valid cases was 58 eyes. The CD in the central and paracentral regions of the anterior, middle, and total layer of the cornea increased significantly on the first day after surgery(all P<0.003). At 6 mo after surgery, there was a slight but statistically significant decrease in the CD of the central and paracentral regions of the anterior and the total anterior layer(all P<0.003). Compared with the preoperative baseline values, the RMS HOA, spherical aberration, and vertical coma significantly increased at 6 mo after surgery(all P<0.003), while the change in horizontal coma was not statistically significant. Compared with the preoperative baseline values, the CET in the central, paracentral, and peripheral regions of the cornea, as well as the total average CET in the 0-7 mm range of the cornea increased at 6 mo after surgery(all P<0.003). At 1 d after surgery, CD of the anterior layer and total layer in the central region of the cornea were positively correlated with the CET in the central region(rs=0.327, rs=0.250, all P<0.05). At 6 mo after the surgery, the CD of the middle layer and posterior layer in the central corneal region were negatively correlated with the preoperative spherical equivalent and the change of RMS HOA(all P<0.05).CONCLUSION:The anterior CD decreases at 6 mo after SMILE for high myopia correction, and there is a certain correlation between the changes in CD and some clinical parameters.
