ObjectiveTo discuss the main auxiliary inspection methods and their guiding significance for inguinal hernia.MethodsBy searching literatures and international guidelines, to review the main auxiliary examination methods, such as ultrasound, CT, and MRI.ResultsClinical physical examination combined with ultrasound could increase diagnostic sensitivity. CT could provide surgeons with a better sense of wholeness and structural details, and could be used as a guide for specific types of inguinal hernia. The soft tissue recognition of MRI was good, and it had a good effect on the identification of hidden hernia, mesh conditions, and tissue inflammation.ConclusionEach examination has its own advantages, and should be selected based on clinical practice and medical center conditions.
Objective To evaluate the clinical effectiveness and safety of different mesh fixation techniques in laparoscopic trans-abdominal preperitoneal hernia repair (TAPP) by using network meta-analysis. Methods CNKI, WanFang Data, VIP, CBM, the Cochrane Library, PubMed, Embase, and Web of Science databases were retrieved to collect randomized controlled trials (RCTs) studies comparing different fixation methods of patches in laparoscopic TAPP. The retrieval time limit was from the establishment of the database to March 1, 2022. After two researchers independently screened the literatures, extracted the data, and evaluated the bias risk, Bayesian network meta-analysis was conducted by using R4.1.2 software. Results Twenty-nine RCTs were included, including 4 095 patients. The results of network meta-analysis showed that the risk of chronic postoperative inguinal pain was higher in staples fixation than that of no fixation [OR=0.06, 95%CI (0.01, 0.26), P＜0.001], glue fixation [OR=0.21, 95%CI (0.04, 0.53), P=0.001] and self-gripping mesh [OR=0.09, 95%CI (0.01, 0.52), P=0.009], the incidence of chronic postoperative inguinal pain with suture fixation was higher than that with no fixation [OR=0.10, 95%CI (0.01, 0.70), P= 0.020]. Postoperative visual analogue scale of staples fixation was higher than those of no fixation [MD=–0.90, 95%CI (–1.49, –0.33), P=0.002] and glue fixation [MD=–0.92, 95%CI (–1.35, –0.49), P＜0.001], the postoperative visual analogue scale with suture fixation was higher than those of no fixation [MD=–0.83, 95%CI (–1.61, –0.08), P=0.030] and glue fixation [MD=–0.85, 95%CI (–1.56, –0.13), P=0.020]. There was no significant difference in the incidence of seroma and hematoma, hospital stay and hernia recurrence among different fixation methods. Conclusions The network meta-analysis shows that medical glue and self-gripping mesh have certain advantages in reducing chronic pain after surgery, which may be the better patch fixation method in TAPP. The non fixation mesh will not increase the risk of postoperative recurrence, and can be used in clinical practice. This conclusion needs to be further verified by large sample, long-term follow-up and high-quality RCTs.
Objective
To observe the clinical effect of vacuum sealing drainage (VSD) in the treatment of mesh infection following inguinal hernia repair.
Methods
A total of 24 patients who suffered form mesh infection following inguinal hernia repair and got treatment in our hospital from February 2012 to December 2015 were collected and divided into 2 groups according to the type of treatment, 12 patients (13 sides) of VSD group received treatment of VSD, and 12 patients (13 sides) of conventional group received conventional treatment. Comparison between the 2 groups in mesh retention rate, the wound healing time, hospitalization cost, and hospital stay was performed.
Results
There was significant difference in mesh retention rate〔76.9% (10/13)vs. 30.8% (4/13)〕, the wound healing time〔(20.5±4.4) dvs. (29.7± 6.7) d〕, hospitalization cost〔(18 430.1±7 180.2) RMBvs. (12 201.1±6 453.2) RMB〕, and hospital stay〔(23.5±4.1) dvs. (30.7±6.5) d〕between the VSD group and conventional group (P<0.050). Compared with conventional group, the mesh retention rate and hospitalization cost were higher, the wound healing time and hospital stay were shorter in VSD group.
Conclusions
VSD can effectively control the mesh infection following hernia repair, improve the mesh retention rate. The VSD can also promote growth of granulation tissue in cavity, shorten the wound healing time and hospital stay, but has a high hospitalization cost than conventional treatment.
ObjectiveTo summarize the research status of risk factors of chronic postoperative inguinal pain (CPIP).MethodWe searched and summarized the domestic and foreign literatures about the risk factors of CPIP in recent years.ResultsThere was no doubt that the risk factors of CPIP included preoperative pain, acute pain at postoperative, recurrent inguinal hernia, smaller hernia sac, higher body mass index (BMI), and surgical methods. These effects were controversial such as age, gender, and the mesh. In recent years, hypertension and a past history of chronic pain may also be risk factors for the development of CPIP.ConclusionsThe risk factors of CPIP still need the further study.
Objective To explore the application effect of same-day surgery mode in adult patients with inguinal hernia repair under enhanced recovery after surgery mode. Methods The perioperative data of adults undergoing inguinal hernia repair in the Day Surgery Center of West China Hospital, Sichuan University between August 2020 and March 2022 were analyzed retrospectively. The adult patients with inguinal hernia repair who received routine daytime surgery were taken as the control group (routine group), and the adult patients with inguinal hernia repair who received same-day surgery were selected as the trial group (same-day group). The differences in safety, cost and patient experience between the two groups were compared and analyzed. Results A total of 319 patients were included, including 152 in the routine group and 167 in the same-day group. There was no significant difference in gender, education level, occupation and hernia ring diameter between the two groups (P>0.05). The age of the patients in the same-day group was older than that in the routine group [(49.49±12.88) vs. (46.41±14.12) years, P<0.05]. The hernia position of the two groups was mostly on the right side, but there was a difference in the hernia position (P<0.05). In terms of safety indicators, the majority of patients in the two groups used local anesthesia. The proportion of local anesthesia (98.2% vs. 76.3%), the amount of intraoperative bleeding [2.8 (2.0, 5.0) vs. 1.3 (0.0, 5.0) mL] in the same-day group were higher than those in the routine group, and the operation time [25.2 (20.0, 33.0) vs. 32.3 (26.0, 40.7) min] in the same-day group was shorter than that in the routine group (P<0.05). There was no significant difference between the two groups in the time of getting out of bed and the complications rate on the 3rd and 28th days after operation (P>0.05). There were no intraoperative complications in both groups. In terms of cost indicators, there was no significant difference between the two groups in the hospitalization cost (P>0.05). The surgery cost of the same-day group was higher than that of the routine group [1472.0 (1438.1, 1614.6) vs. 1450.3 (1428.1, 1438.1) yuan, P<0.05]. The drug cost [109.2 (81.3, 138.7) vs. 255.8 (127.0, 261.6) yuan] and the total medical cost [8418.5 (8207.4, 9129.9) vs. 8912.1 (8325.9, 9177.9) yuan] in the same-day group were lower than those in the routine group (P<0.05). In terms of patient experience indicators, the postoperative pain score [0.3 (0.0, 1.0) vs. 0.2 (0.0, 0.0)] and satisfaction score [3.3 (3.0, 4.0) vs. 3.0 (3.0, 3.0)] of the same-day group were higher than those of the routine group (P<0.05). Conclusion Both the same-day surgery mode and the routine surgery mode of adult patients with inguinal hernia repair have high safety, but the same-day surgery mode is more economical and patient satisfaction is higher than the routine surgery mode, which suggest that the same-day surgery mode of adult patients with inguinal hernia repair under enhanced recovery after surgery mode is feasible, safe and economic, and further optimizes and improves the content and quality of daytime surgical medical services.
ObjectiveTo systematically evaluate the clinical effect and safety of robotic inguinal hernia repair (robotic surgery).MethodsThe control studies on robotic surgery in treatment of inguinal hernia were searched in the English databases (PubMed, Cochrane Library, Embase) and Chinese databases (CNKI, Wanfang, VIP). The search time was from the establishment of the database to December 2020. After screening the literatures according to the inclusion and exclusion criteria, the Jadad scale was used to evaluate the literature quality of randomized controlled studies, the Newcastle-Ottawa scale (NOS) was used to evaluate the literature quality of the retrospective studies, and the RevMan5.3 software was used for meta-analysis.ResultsTwelve relevant articles with a total sample size of 7 661 cases that met the criteria were included in this study, including 1 746 cases of robotic inguinal hernia repair (robotic surgery), 4 361 cases of open inguinal hernia repair (open surgery), and 1 554 cases of laparoscopic inguinal hernia repair (laparoscopic surgery). The surgery time of the robotic surgery was longer than that of the traditional (including open and laparoscopic) surgery (P<0.01), open surgery (P<0.01) or laparoscopic surgery (P<0.01); The hospitalization cost of the robotic surgery was higher than that of traditional surgery (P<0.01) and open surgery (P<0.01). However, the readmission rate of the robotic surgery was lower than that of the traditional surgery (P<0.01) and open surgery (P<0.01). There were no significant differences in the other indicators between the robotic surgery and open surgery or laparoscopic surgery (P>0.05).ConclusionRobotic inguinal hernia repair is safe and feasible, which provides us a new way to treat inguinal hernia.
ObjectiveTo compare the outcomes after self-gripping mesh repair to ordinary polypropylene mesh secured with sutures in women’s Lichtenstein hernioplasty.MethodsThe clinical data of 116 female patients with primary unilateral inguinal hernia who were admitted to The First Affiliated Hospital of Zhengzhou University from January 2014 to January 2017 were prospectively analyzed. A randomized controlled trial was performed based on a random number table. All patients were allocated into self-gripping mesh group (PG group) and ordinary polypropylene mesh group (PL group). The outcomes included operative time, post-operative pain score, analgesic used, hospital stay, urinary retention, wound infection, and seroma were recorded. Patients were followed-up after 1 week, 1 months, 3 months, 1 year, and 2 years after operation. Follow-up data included chronic pain, foreign body feeling, affect daily activities, and recurrence.ResultsNinety-nine participants completed follow-up. There were 48 patients in the PG group and 51 participants in the PL group. The operative time of the PG group was significantly shorter than that of the PL group (P=0.045), but there was no significant difference in analgesic used, hospital stay, incidence of urinary retention and wound infection, visual analogue scale (VAS) of wound pain at rest at 1 week postoperatively, VAS of wound pain on coughing at 1 week postoperatively between the two groups (P>0.05). At 1 month after operation, the incidence of foreign body feeling in the PG group was significantly higher than that of the PL group (P=0.031), while there was no significant difference in ratio of VAS≥3 and incidence of affect daily activities (P>0.05). At 3 months, 1 year, and 2 years after operation, there was no significant difference in incidences of foreign body feeling, chronic pain, and affect daily activities between the two groups (P>0.05). There was one recurrence in the PL group and none in the PG group, without a significant difference (P=0.248).ConclusionThe surgical outcomes of self-gripping mesh are comparable to the ordinary polypropylene mesh with a reduced operation time in women’s Lichtenstein hernioplasty.
Objective
To investigate the value of applying closed continuous negative pressure drainage in preventing postoperative complications of inguinal hernia.
Methods
The clinical data of 107 adult male patients diagnosed with inguinal giant hernia (incarcerated 16 cases, non-incarcerated 91 cases) undergoing tension-free hernioplasty using the Ultrapro Hernia System (UHS) between April 2011 and June 2016 in our hospital were retrospective analyzed. Prophylactic use of antibiotics was not adopted except patients with incarcerated hernia, diabetes, or elderly. Multi-lateral hole plasma drainage tube were used in 61 patients, 46 cases without indwelling plasma tube. The postoperative scrotum pain, scrotal hematoma, scrotal effusion, and incision infection of two groups patients were observed.
Results
Of the 61 patients with plasma drainage, the mean drainage time was 2 days, the longest was 5 days. Postoperative scrotal pain was found in 2 cases (3.3%) without scrotal hematoma or scrotal effusion. Of the 2 patients, the drainage of 1 case was obstructed, the drainage was extubated and the patient was cured and discharged after 5 days by sucking the drainage tube using empty needle. The average hospital stay in this group was 4 days. Of the 46 patients without plasma drainage, 7 patients (15.2%) suffered scrotal pain, 7 patients (15.2%) suffered scrotal hematoma. The average hospital stay was 6 days. The incidence of scrotal pain and scrotal hematoma was significantly higher in patients without plasma drainage than those with drainage (P<0.05). The condition of scrotal hematoma would be improved after 1–3 times outpatient dressing change and repeated hematoma sucking. One case was not improved after repeated suction, the condition was improved after scrotum incision, drainage, and dressing.
Conclusion
Closed continuous negative pressure drainage potentially prevents oblique hernia pain and scrotal hematoma without increasing the incidence of incision infection or hospitalization time.
Objective To explore the risk factors of chronic postoperative inguinal pain (CPIP) after transabdominal preperitoneal hernia repair (TAPP), establish and verify the risk prediction model, and then evaluate the prediction effectiveness of the model. Methods The clinical data of 362 patients who received TAPP surgery was retrospectively analyzed and divided into model group (n=300) and validation group (n=62). The risk factors of CPIP in the model group were screened by univariate analysis and multivariate logistic regression analysis, and the risk prediction model was established and tested. Results The incidence of CPIP at 6 months after operation was 27.9% (101/362). Univariate analysis showed that gender (χ2= 12.055, P=0.001), age (t=–4.566, P<0.01), preoperative pain (χ2=44.686, P<0.01) and early pain at 1 week after operation (χ2=150.795, P<0.01) were related to CPIP. Multivariate logistic regression analysis showed that gender, age, preoperative pain, early pain at 1 week after operation, and history of lower abdominal surgery were independent risk predictors of CPIP. The area under curve (AUC) of the receiver operating characteristic (ROC) of the risk prediction model was calculated to be 0.933 [95%CI (0.898, 0.967)], and the optimal cut-off value was 0.129, while corresponding specificity and sensitivity were 87.6% and 91.5% respectively. The prediction accuracy, specificity and sensitivity of the model were 91.9% (57/62), 90.7% and 94.7%, respectively when the validation group data were substituted into the prediction model. Conclusion Female, age≤64 years old, preoperative pain, early pain at 1 week after operation and without history of lower abdominal surgery are independent risk factors for the incidence of CPIP after TAPP, and the risk prediction model established on this basis has good predictive efficacy, which can further guide the clinical practice.
ObjectiveTo investigate the relation between preoperative peripheral blood neutrophil/albumin (NEU/ALB) or hypersensitive C-reactive protein (hs-CRP)/ALB ratio and seroma after laparoscopic transabdominal preperitoneal (LTAPP) hernia repair. MethodsThe patients diagnosed with inguinal hernia and underwent LTAPP hernia repair admitted to the Heji Hospital Affiliated to Changzhi Medical College from June 2020 to June 2023 were retrospectively collected. The multivariate logistic regression analysis was conducted to identify the risk factors affecting the occurrence of seroma after LTAPP hernia repair. The area under receiver operating characteristic curve (AUC) and 95% confidence interval (95%CI) were used to evaluate the discriminatory value of preoperative peripheral blood NEU/ALB ratio and hs-CRP/ALB ratio for seroma after LTAPP hernia repair. Delong test was used to compare the discriminatory value of these indicators. The test level was α=0.05. ResultsA total of 357 patients who met the inclusion criteria were included in this study, and the seroma occurred in 42 cases (11.8%). The results of multivariate logistic regression analysis showed that the larger the diameter of the hernia sac [OR (95%CI)=4.654 (2.829, 7.657), P<0.001], the more intraoperative bleeding [OR (95%CI)=3.021 (1.498, 6.094), P=0.002], and the higher NEU/ALB ratio [OR (95%CI)=2.585 (1.618, 4.130), P<0.001] or hs-CRP/ALB ratio [OR (95%CI)=1.874 (1.239, 2.834), P=0.003], the higher the probability of seroma after LTAPP hernia repair. The AUC (95%CI) of NEU/ALB or hs-CRP/ALB indicator for predicting seroma after LTAPP hernia repair was 0.750 (0.702, 0.794) and 0.762 (0.715, 0.806), respectively. The optimal cutoff values were 2.970 and 4.001, with sensitivity of 78.6% and 73.8%, and specificity of 60.3% and 65.7%, respectively. The AUC (95%CI) of the NEU/ALB in combination with hs-CRP/ALB in predicting seroma after LTAPP hernia repair was 0.851 (0.810, 0.886), with sensitivity and specificity of 71.4% and 87.0%, respectively. The AUC of the NEU/ALB in combination with hs-CRP/ALB in predicting seroma after LTAPP hernia repair was higher than that of NEU/ALB (Z=2.864, P=0.004) or hs-CRP/ALB alone (Z=2.956, P=0.003). ConclusionFrom the data analysis results of this study, the occurrence rate of seroma after LTAPP hernia repair is not low, and the occurrence of seroma should be paid close attention to patients with larger hernia sac diameter, more intraoperative bleeding, and higher NEU/ALB or hs-CRP/ALB ratio.
