肠管状吻合器经肛切除直肠占位灶及内窥式直肠息肉切除器设计

The Practice of Tubular Anastomate in Treatment of Rectal Space Occupying Lesion and Design of Endoscopic Cutter Used for Proctopolypus

目的探讨及评价直肠中、下段占位性病灶，尤其是良性病变应用管型肠吻合器经肛切除的价值。方法应用吻合器对36例距肛缘5～12cm直肠占位性病灶经肛进行了切除。就手术方法、时间、复发、并发症及不足之处进行回顾。结果手术时间平均34min。除1例管状绒毛状腺瘤术后早期吻合创缘出血、1例绒毛状腺瘤术后14个月复发外，无其他与本术式有关的并发症发生。结论吻合器在直肠中、下段占位性病灶在一定范围内经肛切除是可行的，但存在一些不足之处需从器械设计上进行改进。

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.
