ObjectiveTo investigate the surgical skills and clinical effects of the laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair in treatment of recurrent inguinal hernia with plug prefix mesh. MethodsThe clinical data such as operation time, intraoperative blood loss, postoperative hospital stay, and postoperative complications of 87 patients with recurrent inguinal hernia reoperated in laparoscopic TAPP after inguinal hernioplasty with plug prefix mesh (recurrent hernia group), in the Department of Gastroenterology and Hernia surgery of the First Affiliated Hospital of Kunming Medical University from January 2011 to December 2013, were retrospectively analyzed, which were compared with the 834 incipient inguinal hernia patients operated first by TAPP (incipient hernia group) at the same time. ResultsThe operations were completed successfully in all of the 921 patients without conversion to open surgery. The operation time and intraoperative blood loss in the recurrent hernia group were significantly more than those in the incipient hernia group (P=0.000, P=0.000), the postoperative hospital stay had no signifcant difference between two groups (P=0.057). No recurrences were observed in the recurrent hernia group and incipient hernia group for following-up of (31±4) months and (28±6) months, respectively. Compared with the incipient hernia group, the rates of postoperative pain on day 30 and seroma on day 1 and 3 were higher in the recurrent hernia group (P=0.001, P=0.040, P=0.003, respectively). There were no severe complications such as collateral damage, foreign body sensation, incision infection, intestinal obstruction and so on in the two groups. ConclusionsThe laparoscopic TAPP inguinal hernia repair is safe and effective for patients with recurrent inguinal hernia with plug prefix mesh. More skills are required to reduce the complications. The operation time and intraoperative blood loss in reoperated patients with recurrent inguinal hernia are more than those in patients with incipient inguinal hernia. The rates of seroma on day 1 and 3 are also higher.
Objective To evaluate the clinical effectiveness of laparoscopic and open tension-free hernia repairs in adults. Methods A fully recursive literature search was conducted in PubMed (2002 to September, 2009), EMBASE (2002 to September, 2009), Cochrane Central Register of Controlled Trials (Issue 3, 2009), CBM (2002 to September, 2009) , CNKI and VIP Chinese Scientific Journals Full-text Database (2002 to September, 2009) in any language. Randomized or quasi-randomized controlled trials of inguinal hernia treated by laparoscopic and open methods in adults were considered for inclusion. The four analyzed outcome variables were chronic pain, long term recurrence, intraoperative complications and postoperative complication. Data related to clinical outcomes were extracted by two reviewers independently. Statistical analyses were carried out using RevMan 5.0 software. Results Eighteen published reports of eligible studies involving 5816 participants met the inclusion criteria. Compared with open methods, laparoscopic inguinal hernia had no significant differences in long-term recurrence rate [OR 1.53, 95%CI (1.00 to 2.34), P=0.05] and postoperative complication rate [OR 0.74, 95%CI (0.52 to 1.05), P=0.09], and had lower tendency chronic pain [OR 0.45, 95%CI (0.34 to 0.59) , Plt;0.000 01] with statistical significance. There were significant differences in intraoperative complications between the two groups [OR 2.15, 95%CI (1.32 to 3.53), P=0.002]. Conclusion Current evidence suggests that laparoscopic hernia repair is superior to open methods in chronic pain .There is no significant difference in long-term recurrence rate and postoperative complications between the two methods. More studies are needed for intraoperative complications and other long-term postoperative complications.
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.
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 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 properties of hernia repair mesh of different materials used in clinical practice, so as to provide reference for clinical selection of numerous meshes at present. MethodThe literatures of different materials of hernia mesh in the treatment of abdominal hernia and inguinal hernia at home and abroad were reviewed.ResultsThe synthetic mesh, especially the polypropylene mesh with wide-pore mesh in the midweight mesh, might be the most ideal synthetic mesh. The new coating material improved the defect of polypropylene material to a great extent. The status of biological mesh in complex hernia repair had been waxed, and it had a tendency to be replaced by absorbable synthetic mesh.ConclusionsCurrently, there is no single mesh suitable for all types of hernia repair. Polypropylene mesh is still an effective and low cost mesh material, and there may be more room for the development of absorbable synthetic materials and antimicrobial coatings.
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.
Objective To evaluate the clinical experience and skills of laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection in order to spread and popularize this kind of operation. Methods Under general anesthesia, 32 patients (42 sides) with inguinal hernias were repaired by laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a dissection balloon from August 2005 to December 2007. Results All of operations were successfully performed. The operative time was 60-120 minutes, the blood loss was 20-60 ml, and the length of postoperative hospitalization was 3 days. All cases were followed up for 8 to 18 months and found no recurrence. Conclusion Laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection is feasible, reliable and effective, offering a low recurrence rate, while its price is higher than tension-free herniorrhaphy by traditional method.
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.
