Parastomal herniation is a common complication after stoma formation. The incidence can be reduced by using an extraperitoneal technique, limiting the size of the trephine to 1.5-2.0 cm or by strengthening with a mesh. If an intraperitoneal technique is used the intestine should be brought out through the rectus muscle. Generally, the symptoms are easily controlled with a support belt. Various techniques have been advocated for surgical repair. Fascial repair alone should no longer be performed owing to an unacceptably high recurrence rate, but should be combined with a prosthetic mesh. Relocation of the stoma should be performed for primary repairs.
造口旁疝是造口形成后的常见并发症。采用腹膜外技术、将环钻尺寸限制在1.5 - 2.0厘米或使用补片加强可降低其发生率。若采用腹膜内技术,应将肠管经腹直肌引出。一般来说,使用支撑带症状很容易得到控制。已经提出了各种手术修复技术。由于复发率高得难以接受,不应再单独进行筋膜修复,而应与人工补片联合使用。初次修复时应进行造口移位。
