肛瘘切开悬浮挂线术对肛管直肠压力和肛门功能影响的临床观察

为了探讨肛瘘切开悬浮挂线术治疗复杂性肛瘘的临床疗效，对采用肛瘘切开悬浮挂线术（47例，治疗组）与肛瘘切开引流术（21例，对照组）治疗的68例患者手术前后直肠肛门反射（RAR）、肛管最大收缩压（AMCP）、肛管最长收缩时间（AL—CT）、肛管静息压（ARP）、直肠静息压（RRP）进行测定，并进行对比分析。结果显示，68例肛瘘患者术后RRP和ARP较术前明显降低；治疗组ARP和AMCP较对照组明显增高，ALCT较对照组明显延长。结果表明，肛瘘手术对肛管功能有不同程度的影响，肛瘘切开悬浮挂线术优于肛瘘切开引流术，对肛管直肠功能影响较小，能更好地保护肛门功能。

Clinical Observation on the Effect of Incision and Suspended Thread-Drawing for Anal Fistula on Anorectal Manometric Pressure and Anal Function

The objective of the study was to assess the therapeutic efficacy of incision and suspended thread-drawing （ISTD） in the treatment of complex anal fistula through anorectal manometry. Forty seven patients with complex anal fistula underwent ISTD（the study group） and twenty one patients underwent incision and drainage （the control group）. Pre- and postoperative rectal anal reflex（RAR）, anal maximal contraction pressure（AMCP）, anal longest contraction time （ALCT）, anal rest pressure （ARP） and rectal rest pressure（RRP）were measured for all the patients in the two groups. As results, PoStoperative：RRP and ARP were markedly lower in all the 68 cases,while ARP and AMCP were more increased and ALCT was more prolong in the study group than in the control group. These reveal that anal fistula operation has certain influence on anal function;ISTD has less irritating influence on anal function.
