В исследование включены 56 пациентов с экстрасфинктерными свищами 3-4 степени сложности. Всем пациентам проведена модифицированная процедура FiLaC с иссечением основного свищевого хода и его пересечением на уровне анального сфинктера с проведением лазерного световода через эту часть свищевого хода до его внутреннего отверстия. Воздействие осуществляется водопоглощающим лазером Biolitec мощностью 13 Вт и плотностью энергии 100 Дж/см. Внутреннее свищевое отверстие ушивали Z-образным рассасывающимся швом (Викрил 2.0).</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. После иссечения свищевого хода в ишиоректальном пространстве до стенки анального сфинктера лазерный световод, из-за рубцовых изменений, не удалось провести до внутреннего отверстия свища в 6 случаях. Из 50 больных, перенесших оперативное вмешательство с применением технологии FiLaC, прослежено 39 (78%) пациентов (медиана наблюдения 27 месяцев). Из них 20 пациентов с III степенью сложности свища и рецидив в данной категории отмечен у 7 (35%) пациентов, тогда как из 19 пациентов с IV степенью сложности свища, рецидив наблюдался в 100% случаев.</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Исследование показало целесообразным использование технологии FiLaC при экстрасфинктерных свищах 3 степени сложности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>AIM</title><p>AIM: to assess efficacy of FiLaC technology for extrasphincteric fistulas.</p></sec><sec><title>PATIENTS AND METHODS</title><p>PATIENTS AND METHODS: the retrospective cohort study included 56 patients with extrasphincteric fistulas of Grade III and IV. All patients underwent a modified FiLaC procedure, which consisted of excision of the fistula tract, preservation of the fistula tract inside anal canal with its laser exposure by water-absorbing Biolitec laser power of 13W and energy density of 100 J/cm. Internal fistula opening was closed with a Z-shaped absorbable suture.</p></sec><sec><title>RESULTS</title><p>RESULTS: after fistula tract excision up to the anal canal we failed to insert laser probe to the internal fistulous opening in 6 (10.7%) patients due to scars. Thirty-nine (78.0%) 50 patients, who underwent FiLaC procedure were under observation with median follow-up of 27 months. Twenty (51.3%) patients had fistulas of Grade III with the recurrence occurred in 7 (35.0%) patients. Among 19 (48.7%) patients with fistulas Grade IV the recurrence was detected in all cases.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: FiLaC procedure is effective only for extrasphincteric fistulas Grade III.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>FiLaC</kwd><kwd>экстрасфинктерные свищи</kwd><kwd>лазерные технологии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FiLaC</kwd><kwd>extrasphincteric fistulas</kwd><kwd>laser technology</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Богормистров И.С., Фролов С.А., Кузьминов А.М. и соавт.
