Much of the lateral internal sphincterotomy (LIS) complications is related to LIS incision. In this study, incisions sutured primarily or left to secondary healing after open LIS procedure are compared regarding the wound healing and complications associated with wounds.
Planning a prospective, randomized clinical study, 39 patients were separated into two groups. Open LIS was performed on both of the groups. While the incisions of the patients in group 1 (n = 22) were closed with two interrupted sutures using 3-0 chromic catgut, the incisions of the patients in group 2 (n = 17) were left open. The patients were followed up for 90 days postoperatively.
Hematoma in 1 (4.5%), ecchymosis in 7 (31.8%), and wound infection in 1 (4.5%) developed in patients of group 1. In this group no significant external bleeding was seen. Wound healing duration was 15.05 +/- 5.60 days. In group 2 no hematoma developed (P = 0.98), but 2 (11.7%) ecchymoses (P = 0.25), 4 (23.5%), wound infections (P = 0.14), and 3 (17.6%) postoperative significant external bleedings (P = 0.07) were seen. Wound healing duration was 33.94 +/- 6.67 days (P <0.001).
To achieve early wound healing, primary closure of open LIS incision is useful, but this technique has no significant effect on wound-related complications in comparison with secondary healing.
大部分外侧内括约肌切开术（LIS）并发症与LIS切口有关。在本研究中，比较了开放LIS手术后一期缝合切口或任其二期愈合的伤口愈合情况及与伤口相关的并发症。
计划进行一项前瞻性随机临床研究，将39例患者分为两组。两组均行开放LIS手术。第1组（n = 22）患者的切口用3-0铬制肠线间断缝合2针关闭，第2组（n = 17）患者的切口敞开。对患者进行术后90天的随访。
第1组患者发生1例（4.5%）血肿、7例（31.8%）瘀斑和1例（4.5%）伤口感染。该组未见明显的外出血。伤口愈合时间为15.05±5.60天。第2组未发生血肿（P = 0.98），但出现2例（11.7%）瘀斑（P = 0.25）、4例（23.5%）伤口感染（P = 0.
