目的 探讨保留括约肌虚挂线法治疗高位肛周脓肿的临床疗效。 方法 2009年10月－2010年10月采用随机对照试验，对52例高位肛周脓肿患者施行手术治疗，其中保留括约肌虚挂线法（治疗组）26例，切开挂线引流法（对照组）26例。对两组患者术后6个月肛瘘发生率、切口愈合时间、术后1～15 d每晚疼痛视觉模拟评分（VAS）和术后6个月痊愈患者肛门功能后遗症发生率进行比较。 结果 术后6个月，治疗组和对照组肛瘘发生率分别为4.0%和3.8%，差异无统计学意义（P＞0.05）。术后7～15 d治疗组VAS评分均低于对照组，差异有统计学意义（P＜0.05）。两组切口愈合时间分别为（19.05 ± 6.71）d和（21.42 ± 8.40）d，差异有统计学意义（P＜0.05）。术后6个月治疗组痊愈患者肛门功能全部正常，对照组后遗症发生率为12.0%，两组比较差异有统计学意义（P＜0.05）。 结论 保留括约肌虚挂线治疗在术后疼痛、切口愈合时间和保护肛门功能等方面明显优于切开挂线引流治疗，是一种治疗高位肛周脓肿较为理想的方法。
ObjectiveTo investigate the expressions of stromal cell-derived factor-1 (SDF-1) and chemokine receptor-4 (CXCR4) in local tissues of perianal abscess and their relationships with clinicopathological features and prognosis of patients.MethodsA total of 47 patients with perianal abscess (perianal abscess group) and 58 patients with mixed hemorrhoids (mixed hemorrhoids group) were selected for the study. The tissues were collected during the operation. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expressions of SDF-1 mRNA and CXCR4 mRNA in local tissues of the two groups, the positive expressions of SDF-1 protein and CXCR4 protein in local tissues were detected by immunohistochemistry, and the relationships between the expressions of SDF-1 and CXCR4 protein and the clinical characteristics, prognosis of patients were analyzed.ResultsThe expression levels of SDF-1 mRNA and CXCR4 mRNA in the perianal abscess group were higher than those in the mixed hemorrhoids group, and the positive rates of SDF-1 protein and CXCR4 protein in the perianal abscess group were higher than those in the mixed hemorrhoids group too (P<0.05). The expressions of SDF-1 protein and CXCR4 protein in perianal abscess tissues were both not related to sex, age, location of abscess, and course of disease (P>0.05), but was related to abscess diameter, healing time, and anal fistula (P<0.05). The non-recurrence rates of SDF-1 protein-negative group and CXCR4 protein-negative group were lower than those of SDF-1 protein-positive group and CXCR4 protein-positive group respectively (P<0.05).ConclusionSDF-1 and CXCR4 molecular are up-regulated in the local tissues of perianal abscess, which are related to the size of abscess, healing time, anal fistula, and recurrence of patients.
OBJECTIVE: To observe the curative effects of basic fibroblast growth factor (bFGF) on anus wound healing. METHODS: From April 1996 to December 2000, out of 109 patients with anus trauma, hemorrhoidectomy or fistula resection, 68 were treated with bFGF as the experimental group, while 41 were treated routinely as the control group. The healing of the wound, the general and local reaction were observed. RESULTS: The healing time of the experimental group was(17.00 +/- 1.54) days while that of the control group was(20.00 +/- 1.16) days (P lt; 0.01). Three weeks after operation, the healing rates of the experimental and control groups were 97.1% and 87.8%, respectively (P lt; 0.01). No general or local detrimental reactions were found in two groups. CONCLUSION: Local application of bFGF can accelerate the healing of anus wound, and the patients have little pain.

ObjectiveTo discuss the effectiveness of deep inferior epigastric artery perforator flap to repair perineal and perianal cicatricial contracture. MethodsBetween March 2007 and December 2013, 23 patients with perineal and perianal cicatricial contracture were treated with deep inferior epigastric artery perforator flap. There were 15 males and 8 females, aged from 21 to 62 years (mean, 42 years). Burn depth was III degree. The burning scars involved in the fascia, even deeper, which was rated as peripheral type (mild stenosis of the anal region and perianal cicatricial contracture) in 13 cases and as central type (severe stenosis of the anal region and anal canal with shift or defect of external genitalia) in 10 cases. All patients had limited hip abduction and squatting. Repair operation was performed at 3 months to 2 years (mean, 6 months) after wound healing. The size of soft tissue defects ranged from 10 cm×6 cm to 28 cm×13 cm after scar excision and release. The size of flaps ranged from 12 cm×7 cm to 30 cm×15 cm. The donor site was sutured directly in 16 cases and repaired by autograft of skin in 7 cases. ResultsThe flap had distal necrosis, distal cyanosis, and spotted necrosis in 1 case, 2 cases, and 1 case respectively, which were cured after symptomatic treatment;the other flaps survived and wound healed primarily. Twenty-one patients were followed up 6 months to 2 years (mean, 1 year). Nineteen patients had good appearance of the perinea and position of external genitalia, normal function of defecation function;stenosis of the anal region was relived, and the flaps had good texture and elasticity. Linear scar contracture was observed at the edge of flap in 2 cases, and the appearance of the perineum was restored after Z plasty. The hip abduction reached 30-40°. No abdominal hernia was found at donor site. ConclusionDeep inferior epigastric artery perforator flap has stable blood supply and flexible design, which is similar to the perianal and perineal tissues. The good effectiveness can be obtained to use this flap for repair of perineal and perianal cicatricial contracture.
Objective To explore the application effect of the clinical pathway for perianal day surgery based on enhanced recovery after surgery (ERAS) concept. Methods The case data of patients who underwent perianal surgery in the Department of Anorectal Surgery of Gansu Provincial Hospital between January and October 2023 and patients who underwent perianal day surgery based on the ERAS clinical pathway in the Ambulatory Surgery & Chemotherapy Centre of Gansu Provincial Hospital were retrospectively collected. The patients in the Department of Anorectal Surgery were defined as the control group, while the patients in the Ambulatory Surgery & Chemotherapy Centre were defined as the pathway group. The differences in indicators such as hospitalization cost, average hospitalization time, preoperative hospitalization time, surgical time, intraoperative bleeding, patient satisfaction, and postoperative follow-up between the two groups of patients were analyzed. Results A total of 400 patients were included, with 200 in each group. The differences between the two groups in gender and age were not statistically significant (P>0.05), the Visual Analogue Scale of the pathway group was lower than that of the control group (P<0.05), and the Kolcaba Comfort Scale score was higher than that of the control group (P<0.05). The hospitalization cost, average hospitalization time, preoperative hospitalization time, and surgical time of the pathway group were all lower than those of the control group (P<0.05), and there was no statistically significant difference in intraoperative bleeding between the two groups (P>0.05). The satisfaction rates of the pathway group and the control group were 90.5% and 86.0%, respectively, and there was no statistically significant difference between the two groups (P>0.05). The follow-up results showed that perianal day surgery did not increase the discomfort of patients after discharge. Conclusions The clinical pathway for day surgery based on ERAS concept is more conducive to the postoperative recovery of patients undergoing day surgery, reducing medical costs, improving medical quality, and increasing patient satisfaction. It is worthy of clinical promotion and application.
ObjectiveTo evaluate clinical curative effect of sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess. MethodsOne hundred and twenty hospitalized patients diagnosed as horseshoe-shaped perianal abscess were analyzed by prospective, random, single-blind, parallel-group design method, and were randomly divided into two groups, one group of sphincter preservation method of improved minimally invasive surgery (observation group), another group of traditional method of hanging line drainage and multiple incisions of radian shape (control group). The cure rate, long-term recurrence, postoperative pain score within 9 d, hospitalization time, incision healing time, scar area after healing, postoperative anal function score and perioperative and long-term complications were compared in these two groups. ResultsAll the operations were successfully completed in these two groups. There were 56 cases of primary healing in the observation group and 55 cases of primary healing in the control group. Compared with the control group, the postoperative pain score on day 2-4 or on day 7-9 was lower (P < 0.05), the incision healing time was shorter (P < 0.05), and the postoperative anal function score was lower (P < 0.05) in the observation group. There was no incision infection and hemorrhoea in these two groups. The hospitalization time, scar area after healing, incidence rate of urinary retention, hepatic and renal dysfunction, and the total white blood cells > 10.0×109/L had no significant differences between these two groups (P > 0.05). There was no long-term recurrence, anal stenosis, and anal incontinence during following-up of 6 months in these two groups. ConclusionPreliminary research results show that sphincter preservation method of improved minimally invasive surgery to primary cure for horseshoe-shaped perianal abscess has a reliable clinical curative effect, fast healing, and less postoperative complications.
