Objective To study anatomy of mortis corona vascular and analyze its characteristics and clinical significances in laparoscopic total extraperitoneal hernia repair (TEP). Method The clinical data of 45 patients with inguinal hernia underwent laparoscopic TEP from July 2013 to October 2015 in the Fourth People’s Hospital of Zigong City were collected. Results ① There were 45 patients with inguinal hernia a total of 52 bilateral inguinal hernias (15 direct hernias, 37 oblique hernias). The total appear rate of corona mortis vascular was 61.5% (32/52). The appear rate of corona mortis artery was significantly higher than that of the corona mortis vein〔46.2% (24/52)versus 34.6% (18/52),P<0.05〕, the diameter of the corona mortis artery was significantly smaller than that of the corona mortis vein〔(3.2±0.3) mmversus (3.4±0.4) mm,t=2.231,P<0.05〕. ② The appear rates of corona mortis artery and vein in the male patients were significantly higher than those of the female patients (P<0.05). Compared with the female patients, the age of onset was older (P<0.05), thickness of abdominal wall was thinner (P<0.05), diameter of corona mortis vascular was bigger (P<0.05) in the male patients. ③ The total appear rate of corona mortis vascular in the patients with direct hernia was significantly lower than that of the patients with oblique hernia (P<0.05). The age of onset of the patients with direct hernia was significantly older than that of the patients with oblique hernia (P<0.05). Conclusions There is a higher appear rate of corona mortis vascular in patients with oblique hernia, which in male patients is higher as compared with female patients. Age of onset of male patient with inguinal hernia is older than that of female patient with inguinal hernia. It suggests that appear of corona mortis vascular might be associated with degeneration of abdominal wall. It has a certain role for localization and avoidance of corona mortis vascular in TEP.
ObjectiveTo systematically evaluate the effect of single-port totally extraperitoneal (SPTEP) and conventional totally extraperitoneal (CTEP) inguinal hernia repair in treatment of inguinal hernia. MethodsPubMed, Cochrane Library, Embase, WanFang Data, VIP, and CNKI databases were electronically searched and the randomized controlled trial (RCT) and non-RCT studies on the efficacy and safety of SPTEP versus CTEP for patients with inguinal hernia from January 2010 to November 2019 were collected. Two reviewers independently screened literatures, extracted data, and assessed risk of bias of included studies, then the meta-analysis was performed by using RevMan5.3 software. ResultsA total of 17 clinical studies were included in the analysis, with 1 106 cases in the SPTEP group and 966 cases in the CTEP group. The results of meta-analysis showed that: the hospital stay [SMD=–0.12, 95%CI (–0.22, –0.02), P=0.01] and the time to resume normal activity [SMD=–1.17, 95%CI (–2.10, –0.23), P=0.01] were shorter, the satisfaction score of incision scars [SMD=0.92, 95%CI (0.31, 1.53), P<0.01] was higher in the SPTEP group as compared with the CTEP group. However, the operative time of SPTEP group was longer than that of the CTEP group both for unilateral inguinal hernia [MD=4.08, 95%CI (0.34, 7.83), P=0.03] and bilateral inguinal hernia [MD=5.53, 95%CI (0.39, 10.68), P=0.04]. There were no statistical differences in the postoperative pain score (24 h and 7 d), incidence of postoperative complications, the rate of patients satisfied with the incision, and hospitalization costs between the two groups (P>0.05). ConclusionsFrom the results of this meta-analysis, SPTEP has some certain advantages in shortening hospital stay and returning to normal activity time, and improving incision satisfaction. However, compared with CTEP, mean operative time of SPTEP is longer. Although SPTEP has developed for several years, it is difficult to replace CTEP.
ObjectiveTo observe the pathological changes of the peritoneum before and after the total extraperitoneal herniorrhaphy via preperitoneal space approach for incisional hernia in rats, and to explore the effects on the ischemia and necrosis of the peritoneum and its function after the extensive dissociation of the preperitoneal space and the implantation of the patch. MethodsA total of 80 SD rats were randomly divided into normal control group (n=8), hernia model control group (n=8), patch implantation blank control group, and hernia model patch repair group. Eight rats were randomly selected at week 1, 4, 8, and 12 after patch implantation from the patch implantation blank control group and hernia model patch repair group. The normal peritoneum and surrounding tissues were taken from the normal control group, and the peritoneal tissues near the incision were taken from the hernia model control group, patch implantation blank control group, and the hernia model patch repair group. The hematoxylin-eosin staining was performed to observe the pathological changes of the peritoneum. The degrees of inflammatory cell infiltration and fiber hyperplasia among the different groups were compared. Results① Comparison of the degree of inflammatory cell infiltration in the peritoneal tissue, which in the patch implantation blank control group at week 1 and 4 after patch implantation was more severe than the normal control group (P＜0.001, P=0.005) respectively, which at week 8 after patch implantation was alleviated (P=0.021) as compared to the 1st week after patch implantation in the patch implantation blank control group, which had no statistic difference between the patch implantation blank control group and normal control group (P=0.102), which at the 1st week after patch implantation was more severe than hernia model control group (P=0.014), which was alleviated at week 8 and 12 after patch implantation as compared to the 1st week after patch implantation in the hernia model patch repair group (P=0.040, P=0.040), which had no statistic differences between the patch implantation blank control group and the hernia model patch repair group at same time point after patch implantation (P>0.05). ② Comparison of the degree of fiber hyperplasia in the peritoneal tissue, which at week 1, 4, and 12 after patch implantation was more severe (P＜0.001, P=0.003, P＜0.001, respectively) in the patch implantation blank control group as compared with the normal control group; which was alleviated at week 8 after patch implantation as compared to the 1st week after patch implantation in the hernia model patch repair group（P=0.017); which was more severe in the hernia model control group as compared with the normal control group (P=0.012); which had no statistical differences between the hernia model control group and the hernia model patch repair group at different time point (P>0.05); which had no obvious change between-time point in the hernia model patch repair group (P>0.05); which had no statistic differences between the patch implantation blank control group and the hernia model patch repair group at same time point after patch implantation (P>0.05). ConclusionsBased on the experimental results of this study, hernia itself will not stimulate inflammatory cell infiltration and fiber hyperplasia of peritoneal tissue. However, during the process of total extraperitoneal herniorrhaphy via preperitoneal space approach, extensive peritoneal space dissociation and patch implantation will cause peritoneal injury and affect its function. But through the body itself repair, the function caused by peritoneal injury can be fully restored to normal status on the 8th week after patch implantation.
ObjectiveTo explore the effectiveness of traditional Chinese medicine (TCM) acupuncture analgesia after laparoscopic total extraperitoneal inguinal hernia repair (TEP), aiming to reduce the use of analgesics post-surgery. MethodsPatients who underwent unilateral TEP in the Department of Hernia and Abdominal Wall Surgery at our hospital from May 2022 to May 2023 were selected as research subjects. Those who met the inclusion and exclusion criterias were randomly assigned to three groups: TCM acupuncture analgesia group, traditional Chinese medicine acupuncture analgesia plus western medicine analgesia group (referred to as Chinese and western medicine analgesia group), and western medicine analgesia group. The basic information, postoperative numerical rating scale (NRS) pain scores, postoperative recovery indicators, and complication rates of the three groups were analyzed and compared.ResultsThere was no statistically significant differences in the basic data of patients across the three groups (P>0.05). There were significant differences in NRS score, recovery time of intestinal function, first urination time after operation and first ambulation time after operation at each time point after analgesia (6 h, the next morning, 48 h, 72 h and 96 h after operation) among the three groups (P<0.05). The NRS scores in both the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group were lower than those in the western medicine analgesia group (P<0.05), Additionally, postoperative recovery outcomes were better in the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group compared with the western medicine group (P<0.05). There was no significant difference of the above results compared between the TCM acupuncture analgesia group and the Chinese and western medicine analgesia group (P>0.05). There was no significant difference in postoperative complications among the three groups (P>0.05). ConclusionTCM acupuncture analgesia following TEP surgery is effective and leads to improved postoperative recovery compared with the use of oral analgesics alone, without an increase in adverse reactions.
