Hospital days in local anesthesia were much shorter than that in epidural anesthesia group (P=0.035). Lung complication in local anesthesia were much less than that in epidural anesthesia group (P=0.015). Other indicators were no significant difference between the two groups (P > 0.05). ConclusionTension-free herniorrhaphy under local anesthesia in elderly patients is safe, reliable, less invasive method with low costs, slight postoperative pain, and worthy of promotion.
Objective To investigate the application of transverse fascia in inguinal hernia repair. Methods In this study, 617 patients underwent inguinal hernia repair between January 1990 and December 2005 in our hospital were included, which were divided into two groups according to different operative ways: transverse fascia method group (n=337) and Bassini method group (n=280). Then intraoperative results, postoperative complications, and rehabilitated results of patients in two groups were compared. Results Compared with Bassini method group, the patients in transverse fascia method group did not show significant difference in operative time and blood loss during operation (Pgt;0.05). The differences of severe postoperative pain, testicular swelling, the time of the body’s restore for normal activities, and recurrence rate of patients between two groups were significant (Plt;0.05), while the difference of hematoma of scrotum and infection of incisional wound (Pgt;0.05). Conclusion The strengthening of posterior wall by transverse fascia and reconstruction of inner ring is a simple and effective method for inguinal hernia repair.
Objective To discuss the surgical treatment and experience of mesh infection after prosthetic patch repair of inguinal hernia. Methods The clinical data of 67 cases of mesh infection after prosthetic patch repair who were treated in Chao-Yang Hospital from Jan. 2011 to Jun. 2012 were retrospectively analyzed. Results All patients were treated with surgical operation successfully， including removing the infected mesh and surrounding tissues， primary suture， and a placement of wound drainage， without replacement of a new patch substitute. The hospital stay of the patients was 10-25days with an average of 16days. Of the 67 patients， 51 patients got primary healed and the other 16 patients healed delayed after local dressing change due to the superficial infection following stitch removal. Sixty-six patients were followed-up for 6-24 months （average of 20 months） after operation without recurrence and complication， including seroma， wound infection， intestinal fistula， and postoperative pain. Conclusions The treatment of mesh infection after inguinal hernia repair is very complicated， but the primary suture repair and a placement of wound drainage after removing infected mesh with complete debridement is a effective therapy for it.
ObjectiveTo compare the efficiency of total extraperitoneal inguinal herniorrhaphy with laparoscopic technique using an innovative self-gripping mesh and polypropylene mesh. MethodsThe clinical data of 142 cases of unilateral inguinal hernia who underwent total extraperitoneal prosthesis (TEP) in our hospital form June 2012 to March 2015 were retrospectively analyzed. the operation type was total extraperitoneal inguinal herniorrhaphy with laparoscopic technique. Depending on the kind of mesh, all patients were divided into two groups from the self-gripping mesh group (n=60) and the polypropylene mesh group (n=82). ResultsThere was no significant difference in the operation time, intraoperative blood loss, hospital stay, and The Visual Analogue Score of post-operative (at 12, 24, 48, and 72 hours after operation) between the 2 groups (P>0.05). On the post-operative complications, there was no significant difference in incidences of total complication, scrotal edema, seroma, bladder injury, vascular injury of abdominal, and urinary reten-tion too (P>0.05).

ConclusionInnovative self-gripping mesh is safe and effective, and maybe a good direction of mesh for material development.
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 develop a machine learning model to identify preoperative, intraoperative, and postoperative high-risk factors of laparoscopic inguinal hernia repair (LHR) and to predict recurrent hernia. Methods The patients after LHR from 2010 to 2018 were included. Twenty-nine characteristic variables were collected, including patient demographic characteristics, chronic medical history, laboratory test characteristics, surgical information, and postoperative status of the patients. Four machine learning algorithms, including extreme gradient boosting (XGBoost), random forest (RF), support vector machine (SVM), and k-nearest neighbor algorithm (KNN), were used to construct the model. We also applied Shapley additive explanation (SHAP) for visual interpretation of the model and evaluated the model using the k-fold cross-validation method, receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA). ResultsA total of 1 178 patients with inguinal hernias were included in the study, including 114 patients with recurrent hernias. The XGBoost algorithm showed the best performance among the four prediction models. The ROC curve results showed that the area under the curve (AUC) value of XGBoost was 0.985 in the training set and 0.917 in the validation set, which showed high prediction accuracy. The K-fold cross-validation method, calibration curve, and DCA curve showed that the XGBoost model was stable and clinically useful. The AUC value in the independent validation set was 0.86, indicating that the XGBoost prediction model has good extrapolation. The results of SHAP analysis showed that mesh size, mesh fixtion, diabetes, hypoproteinemia, obesity, smoking history, low intraoperative percutaneous arterial oxygen saturation (SpO2), and low intraoperative body temperature were strongly associated with recurrent hernia. ConclusionThe predictive model of recurrent hernia after LHR in patients derived from the XGBoost machine learning algorithm in this study can assist clinicians in clinical decision making.
ObjectiveTo study the efficacy, the operation skills, and the complications of laparoscopic totally extraperitoneal prosthesis (TEP). MethodsThe clinical data of 1 020 patients received TEP from April 2011 to March 2014 were retrospectively analyzed. The oral feeding time, out of bet time, operation time, hospital stay, hospitalization costs, postoperative complications, and so on were recorded. ResultsAmong the 1 020 patients, the types of hernias were 810 indirect inguinal hernias (including unilateral hernia and bilateral hernia), 118 direct inguinal hernias, 24 femoral hernias, and 68 recurrent inguinal hernias. The surgeries were basically successfully completed in all the patients, including 12 cases (both recurrent hernia) of conversion to laparoscopic transabdominal preperitoneal prosthesis (TAPP). All the patients could take food in a day and get out of bed on day 1 after operation. The unilateral operation time was (48±9.8) min, bilateral was (65±8.6) min. The postoperative hospital stay was 0.5-2.0 d, total hospital stay was (3.48±2.40) d, hospitalization costs was (8 958±1 685) yuan. Main complication was 61 (5.98%) cases of seroma, 48 (4.70%) cases of temporary nerve paresthesia, 23 (2.78%) cases of urinary retention, 9 (0.88%) cases of chronic pain, and 5 (0.49%) cases of abdominal artery injury. No incision infection, visceral injury, small intestinal obstruction, and other serious complications happened. No occurrence occurred with following-up for 1 year. Classification of different hernia complications, the statistical analysis showed that the total incidence of complications of the typeⅣwas highest, then which was in sequence of typeⅢ, typeⅡ, typeⅠ(P < 0.001). ConclusionLaparoscopic TEP is a safe, reasonable repair without tension with small incision, lighter abdominal interference, less pain, early return to normal activities, but it is a difficult technology and has a higher cost.
