Objective To explore the important role of preperitoneal space in laparoscopic transabdominal preperitoneal （TAPP） and totally extraperitoneal （TEP） hernia repair. Methods The clinical data of 66 patients （78 sides） performed laparoscopic TAPP and TEP hernia repair from January 2008 to April 2011 in this hospital were analyzed retrospectively. Results TAPP hernia repair were performed in 16 cases （20 sides），TEP hernia repair were performed in 50 cases （58 sides）. Three cases of TEP hernia repair transferred to TAPP hernia repair. The unilateral operation time was （86.92±36.38） min，intraoperative bleeding was （6.08±3.43） ml. Postoperative complication rate was 16.7% （11/66），including 3 cases of postoperative serum swelling，3 cases of temporary paraesthesia of nerve feeling in the repair area，2 cases of scrotum emphysema，2 cases of urinary retention，and 1 case of intestinal obstruction. There were 2 cases of recurrence. The hospital stay was （4.52±0.99） d. The return to activities and working time was （10.32±1.86） d after discharge. Sixty-six cases were followed up for （18.56±1.96） months （range 1-38 months），the patch infection，chronic pain，and testicular atrophy complications were not been observed. Conclusions Acquainting and mastering laparoscopic preperitoneal space and its important structure are the key to avoid intraoperative and postoperative complications of laparoscopic inguinal hernia repair.
ObjectiveTo observe the effect of transabdominal preperitoneal (TAPP) laparoscopic hernia repair by same-day surgery mode for patients with inguinal hernia. MethodsThe patients who underwent TAPP laparoscopic hernia repair were retrospectively collected in the Day Surgery Center of West China Tianfu Hospital from July 2022 to June 2023. All patients in this study were admitted according to the same-day surgery plan, and those who were admitted to the hospital on the same day, operated on the same day, and returned to their homes on the same day, i.e., those who did not stay in the hospital overnight (the same-day surgery plan of the West China Tianfu Hospital of Sichuan University is now basically in the range of 8∶00–20∶00, and the latest discharge is at 21∶00) were classified as the same-day surgery group; however, the patients whose special cases needed to be postponed due to the condition of their illnesses, or those who were discharged from the hospital after 21∶00 due to safety considerations because of other reasons such as postoperative observation of patients with general anesthesia for a period of less than 2–4 h, or those who had a strong desire to be admitted to the hospital overnight, and whose hospital stay was not more than 24 h, were classified as the non-same-day surgery group. The age, gender, marital status, body mass index, hernia type, surgical site, home address, intraoperative bleeding, operative time, total hospitalization cost, pain score at discharge, unplanned revisit rate within 30 d after surgery, discharge satisfaction were compared between the patients of two groups. ResultsA total of 167 patients underwent TAPP laparoscopic hernia repair were enrolled in this study, including 97 in the same-day surgery group and 70 in the non-same-day surgery group. There were no statistically significant differences in the age, gender, marital status, body mass index, hernia type, surgical site, intraoperative bleeding, operative time, and total hospitalization cost between the two groups (P>0.05). However, it was found that the patients in the non-same-day surgery group had a higher pain score at discharge and a higher proportion of home address outside Chengdu city as compared with the same-day surgery group (P=0.042, P<0.001, respectively); The satisfaction rate of all patients in this group was 100% on the 28th day after discharge, and the unplanned revisit rate within 30 d after surgery was 3.6% (6/167), although which in the same-day surgery group was slightly higher than the non-same-day surgery group, the difference was not statistically significant by Fisher test [4.1% (4/97) versus 2.9% (2/70), P=0.226]. ConclusionFrom the analysis results of this study, TAPP laparoscopic hernia repair for patients with inguinal hernia by the same-day surgery mode is safe, and it can further shorten the hospitalization time as compared with the non-same-day surgery.
Objective To review the clinical operation methods of abdominal incisional hernia. Methods Classification, operation method and fellow-up of 78 patients with abdominal incisional hernia were retrospectively analyzed. Results The average time of fellow-up was 26 months. Nineteen cases were repaired with simple suture with 3 cases (15.8%) recurrence, 57 cases were repaired with man-made material with 2 case （3.4%） recurrence. Conclusions Individual operation method should be chosen according to body condition, classification of the size of abdominal loss and abdominal hypertension. It is an effective method to repair the hernia of abdominal incision with man-made material.
Objective To explore the surgical techniques and the clinical effect of laparoscopic transabdominal preperitoneal （TAPP） hernia repair for recurrent inguinal hernia. Methods Clinical data of 130 cases of recurrent inguinal hernia who underwent TAPP hernia repair from Mar. 2009 to Dec. 2012 in Beijing Chao-Yang Hospital of Capital Medical University were retrospectively analyzed. Results Operations were completed successfully in 129 cases and 1 case was converted to open surgery. The operation time was （54.5±16.1） min （30-100min） and the hospital stay was （4.5±2.1） d （2-11d）. The rates of postoperative pain， hydrocele， and urinary retention were 3.8% （5/130），11.5% （15/130）， and1.5% （2/130） respectively. There were no complications such as foreign body sensation，wound infection，and intestinal obstruction after operation. All cases were followed-up for 7-50 months 〔（24.3±11.3） months）〕 with no recurrence was observed. Conclusions Laparoscopic TAPP hernia repair for recurrent inguinal hernia has advantages of minimal invasion and few complications，who is safe and effective.
Objective To compare the postoperative outcomes of elderly and non-elderly patients undergoing inguinal hernia repair in same-day surgery mode, and explore the utility and safety of same-day surgery mode in inguinal hernia repair. Methods Patients who underwent inguinal hernia repair in Day Surgery Center, West China Hospital of Sichuan University between January 1st 2021 and October 31st 2021 were prospectively included. The patients were divided into elderly group (≥60 years old) and non-elderly group (18-59 years old). The preoperative conditions, postoperative outcomes, discharge readiness and social support of the two groups were analyzed. Results A total of 451 patients were enrolled, including 111 elderly patients and 340 non-elderly patients. The male proportion, prevalence rates of preoperative comorbidities, and bilateral inguinal hernia proportion in the elderly group were significantly higher than those in the non-elderly group (P<0.05), and the body mass index in the elderly group were significantly lower than that in the non-elderly group (P<0.05). There was no significant difference in anesthesia method, analgesic method, bleeding volume, or surgery time between the two groups (P>0.05). The postoperative pain score of the non-elderly group was higher than that in the elderly group (Z=–2.226, P=0.026), but there was no statistically significant difference in the rate of postoperative unplanned analgesia, rate of discharge delay, pain score on the third day after discharge, re-consultation within one month after discharge, complications within one month after discharge, or post-discharge satisfaction (P>0.05). The total score of social support was higher in the elderly group than that in the non-elderly group (31.77±3.04 vs. 29.75±4.78; t=4.182, P<0.001). Conclusion The same-day surgery mode for inguinal hernia repair is feasible and safe in elderly patients and worthy of implementation.
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.
Objective To retrospectively compare short-term outcomes and health economics of PHS versus UHS for inguinal hernia repair. Methods We included 105 patients suffering from reducible inguinal hernia hospitalized in the First Affiliated Hospital of Lanzhou University from September, 2007 and September, 2012. The referred hernia types involved direct and indirect hernia (unilateral and bilateral). Based on different repair materials, the patients were divided into two groups, PHS group (n=53) and UHS group (n=52). Outcome parameters for comparison included incidences of seroma and scrotum edema, hospital duration, costs, etc. Results There were no differences in age, sex, hernia type, incidences of seroma and scrotum edema after surgery, hospital duration and costs between the two groups. However, the patients in the PHS group spent less money than those in the UHS group regarding the costs of materials and hospitalization, with significant differences. Conclusion For inguinal hernia repair, PHS and UHS are alike in reducing short-term complications, but PHS can significantly reduce patients’ economic burden due to less costs.
Objective To compare the feasibility， safety， and efficiency of laparoscopic total extraperitoneal （TEP）hernia repair surgery and laparoscopic transabdominal preperitoneal （TAPP） hernia repair surgery. Methods The clinical data of 95 patients with inguinal hernia who underwent laparoscopic TEP hernia repair surgery （TEP group） and TAPP hernia repair surgery （TAPP group） from Mar. 2010 to Oct. 2013 in our hospital were retrospectively analyzed， and clinical parameters including operation time， intraoperative blood loss， postoperative hospital stay， postoperative comp-lication， and operation cost of 2 groups were compared. Results All the procedures were successful， none of them was converted to open surgery. There was no significant difference between TEP group and TAPP group when considering operation time 〔（65±16） min vs.（68±17） min〕， intraoperative blood loss 〔（7.0±1.2） mL vs. （8.0±1.4） mL〕， visual pain analogue scale 〔（2.0±1.1） score vs. （1.8±1.1） score〕， postoperative hospital stay 〔（3.1±1.4） d vs. （3.3±1.2） d〕，and time to release to regular activities 〔（4.2±1.0） d vs. （4.5±1.2） d〕， P＞0.05. But the operation cost of TEP group was significantly lower than that of TAPP group 〔（8 033±536） yuan vs. （9 632±643） yuan， P=0.007〕. There were 6 atients （6.3%， 6/95） suffered complications， 3 cases in TEP group and 3 cases in TAPP group， including 3 cases of seroma or hematoma in scrotum， 1 case of transient neurapraxia， and 3 cases of urinary retention. There was no signi-ficant difference in incidence rate of postoperative complication between the 2 groups （P=1.000）. All patients were followed-up for 1-35 months 〔（20.0±10.2） months〕 without recurrence and chronic pain. Conclusions TEP and TAPP hernia repair surgery are feasible， safe， effective， and minimally invasive technique for inguinal hernioplasty. There are advantages and disadvantages of both TAPP and TEP hernia repair surgery， but there is no statistically significant difference regarding intraoperative and postoperative complications.
ObjectiveTo investigate the clinical characteristics and risk factors of chronic pain after laparoscopic inguinal hernia repair.MethodsThe clinical data of 142 cases underwent laparoscopic inguinal hernia repair from January 2013 to December 2017 in The Second Affiliated Hospital of Xiamen Medical College were retrospectively analyzed.ResultsThe incidence of chronic pain after laparoscopic inguinal hernia repair was 12.7% (18/142), and 83.3% (15/18) of the patients were located in the inguinal region. Univariate analysis showed that postoperative chronic pain rates were higher in patients receiving standard patch, large patch, mechanical fixation patch, and with postoperative complications (P<0.05). Multivariate analysis showed that large patch [OR=1.82, 95% CI was (1.18, 5.36), P=0.023], mechanical fixation patch [OR=1.44, 95% CI was (1.07, 3.62), P=0.039], and postoperative complications [OR=2.53, 95% CI was (1.27, 7.31), P=0.011] were independent risk factors for postoperative chronic pain after laparoscopic inguinal hernia repair.ConclusionThe occurrence of chronic pain after laparoscopic inguinal hernia repair is the result of many factors, especially the complications and patch factors.
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.
