Objective To evaluate the clinical value of anastomate in treatment of rectal lesion. Methods The anastomate was used to resect space occupying lesion which was 5~12cm from anal.Then thwe operation procedure,operation time, recurrence complications and correlated problems were summarized.Results The average operation time was 34 minutes. Exceot for one case of anastomtic bleeding and one case of recurrence 14 months post operation.there were No other complications.Conclusions Stapling-resecting the rectal lesion was feasible,but some problems were solved from the design of anastomate.

Objective:To probe the role of CT in guided thalamotomy and posteroventral pallidotomy for Parknson's disease.Methods:With the help of microelectrode guided technique,ipsilateral thalamotomy and pallidotomy were used for 150 Parkinsonian disease.To fix position with CT in operation,the three dimension for target was measured.Results:80 percent of targets orientated by CT tallyed with that recorded by microelectrode electrophysiology.The error of the rest 20% was less than 2 mm on the average.Conclusions:By CT the targets can be accurately located in 3 dimension during operation.The cost of this kind of orientation is 50 percent less than that of SPCT or MRI

Objective:To explore the application value of neuroendoscopic Endoport technique in resection of intracranial lesions involving the interventricular foramen.Methods:A retrospective analysis was performed; 21 patients with intracranial lesions involving the interventricular foramina accepted treatment by neuroendoscopic Endoport technique in our hospital from January 2018 to August 2020 were chosen. The surgical results and prognoses at follow-up were discussed.Results:In these 21 patients, total removal of the lesions was achieved in 19 patients, and subtotal removal in 2 patients; perioperative complications included 1 patient with postoperative hemorrhage and 1 patient with intracranial infection. During the follow-up of 3-30 months, except for 1 patient lost of follow-up, Karnofsky performance scale scores at the last follow-up were 85.5±3.5, and no signs of tumor recurrence were found during the imaging follow-up.Conclusion:Neuroendoscopic Endoport technique can help to safely and effectively remove intracranial lesions involving the interventricular foramen, and the patients enjoy good prognosis.
