腹腔镜经腹膜前腹股沟疝修补术中残端疝囊处理方式对术后血清肿影响的前瞻性研究

目的探讨腹腔镜经腹膜前腹股沟疝修补术(TAPP)术中残端疝囊处理方式对术后血清肿的影响。方法采用前瞻性研究方法。选取2017年10月至2019年3月福建医科大学附属协和医院收治的128例男性原发性腹股沟斜疝患者的临床资料。采用随机数字表法将患者分为两组,患者行TAPP,术中疝囊剥离及横断后将残端缝合固定于腹直肌下缘,设为试验组;患者行TAPP,术中疝囊剥离及横断后将残端游离于腹腔,设为对照组。观察指标:(1)手术情况。(2)随访情况。采用门诊和电话方式进行随访,了解患者术后血清肿、切口感染、慢性疼痛、疝复发情况。随访时间截至2019年6月。正态分布的计量资料以±s表示,组间比较采用t检验。偏态分布的计量资料以M(范围)表示,组间比较采用Mann-Whitney U检验。计数资料以绝对数表示,组间比较采用χ2检验。结果筛选出符合条件的男性患者128例;平均年龄为61岁,年龄范围为47~74岁。128例患者中,试验组60例,对照组68例。(1)手术情况:试验组和对照组患者手术时间分别为(102±34)min和(97±30)min,住院费用分别为(12813±2390)元和(12125±2205)元,两组患者上述指标比较,差异均无统计学意义(t=0.907,1.685,P>0.05)。(2)随访情况:128例患者均获得随访。试验组和对照组术后发生血清肿分别为8例和8例,两组比较,差异无统计学意义(χ2=0.072,P>0.05)。试验组术后发生血清肿患者抽液量为20 mL(4~31 mL),对照组术后发生血清肿患者抽液量为43 mL(23~98 mL),两组比较,差异有统计学意义(Z=-2.013,P<0.05)。试验组和对照组发生血清肿患者术后3个月均无切口感染、慢性疼痛、疝复发。结论TAPP术中疝囊横断后将残端缝合固定于腹直肌下缘和将残端游离于腹腔均能有效修补腹股沟斜疝。疝囊横断后将残端缝合固定于腹直肌下缘可减少术后血清肿抽液量。

A prospective study on effects of treatment of hernia sac stump in laparoscopic transabdominal preperitoneal inguinal hernia repair on postoperative seroma

Objective To investigate the effects of treatment of hernia sac stump in laparoscopic transabdominal preperitoneal inguinal hernia repair(TAPP)on postoperative seroma.Methods The prospective study was conducted.The clinical data of 128 male patients with primary indirect inguinal hernia who were admitted to Fujian Medical University Union Hospital from October 2017 to March 2019 were selected.Patients were divided into two groups by random number method.Patients in experimental group had hernia sac stump sutured and fixed at the lower margin of rectus abdominis after transection of hernia sac in TAPP,and patients in control group had hernia sac stump free in the abdominal cavity after dissection and transection of hernia sac in TAPP.Observation indicators:(1)surgical situations;(2)follow-up.Follow-up using outpatient examination and telephone interview was conducted to detect the incidence of postoperative seroma,incision infection,chronic pain,and hernia recurrence up to June 2019.Measurement data with normal distribution were represented as Mean±SD,and comparison between groups was done using the t test.Measurement data with skewed distribution were represented as M(range),and comparison between groups was done using the Mann-Whitney U test.Count data were described as absolute numbers and percentages,and comparison between groups was analyzed using the chi-square test.Results A total of 128 male patients were screened for eligibility,including 60 patients in the experimental group and 68 patients in the control group.The 128 patients were aged from 47 to 74 years,with an average age of 61 years.(1)Surgical situations:operation time and hospital expenses were(102±34)minutes and(12813±2390)yuan for the experimental group,and(97±30)minutes and(12125±2205)yuan for the control group,respectively,showing no significant difference between the two groups(t=0.907,1.685,P>0.05).(2)Follow-up:all the 128 patients received follow-up.There were 8 cases of seroma in both the experimental group and the control group,with no significant difference between the two groups(χ2=0.072,P>0.05).The extraction volume of patients with seroma was 20 mL(range,4-31 mL)in the experimental group,and 43 mL(range,23-98 mL)in the control group,showing a significant difference between the two groups(Z=-2.013,P<0.05).There was no incision infection,chronic pain or hernia recurrence in 3 months after operation in patients with seroma of either experimental group or control group.Conclusions During TAPP,suture and fixation of the hernia sac stump to the lower edge of rectus abdominis and free hernia sac stump in the abdominal cavity after dissection and transection of hernia sac can effectively repair indirect inguinal hernia.The former method can reduce the extraction volume of seroma after operation.
