UNASSIGNED: This analysis addresses the uncertainty surrounding the efficacy of glue mesh fixation (GMF) compared with tack mesh fixation (TMF) in laparoscopic herniorrhaphy. Our meta-analysis incorporates recently conducted randomized controlled trials (RCTs) to enhance the reference for assessing the efficacy and safety of GMF.
UNASSIGNED: PubMed Central, Google Scholar, Science Direct, and Cochrane Library were extensively reviewed for articles in the English language performed from inception to May 2023 using the keywords \"Glue mesh repair,\" \"Tack mesh repair,\" \"Inguinal Hernia,\" \"Herniorrhaphy,\" \"Laparoscopic,\" \"Mesh Fixation,\" and \"Randomized controlled trials.\"
UNASSIGNED: In this meta-analysis, we incorporated a total of 20 randomized controlled trials, evaluating each article individually using quality ratings. Compared with TMF, GMF demonstrated a significant reduction in the incidence of chronic pain [RR: 0.40, (0.23, 0.68)] and pain scores on postoperative day 1 [MD: -1.07, (-1.90, -0.25)]. We also used funnel plots and Egger\'s regression to test for publication bias.
UNASSIGNED: In summary, this meta-analysis establishes the significance of GMF in reducing chronic pain and postoperative day 1 pain compared with TMF. However, no statistically significant difference was noted between the GMF and TMF groups concerning hematoma, seroma, operation time, recurrence rate, and total complications. Nonetheless, given the small number of cases in this study, the findings must be validated in the future by multicenter, large-sample, high-quality RCTs.

UNASSIGNED: Totally extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) are laparoscopic techniques frequently used in inguinal hernia surgeries. There are very few studies directly comparing the outcomes of TEP and TAPP. The present study compared both techniques\' technical aspects, intraoperative and postoperative early complications.
UNASSIGNED: In this study, 108 patients diagnosed with inguinal hernia underwent laparoscopic surgery between May 2016 and December 2020. Seventy six of these patients (70.4%) underwent TEP, and 32 (29.6%) underwent TAPP. This study was retrospective. However, the data were registered prospectively (including video recordings).
UNASSIGNED: No significant difference was found between the groups regarding age, sex, body mass index, American Society of Anesthesiologist physical status classification, and duration of hospitalization. Although the TEP group had a higher overall complication rate than TAPP, the difference between the two groups was not significant (TEP, 9.2% vs. TAPP, 3.1%, p = 0.979). Two conversions and two recurrences (2.6% each) were observed in TEP. The hematoma was seen in one case in both techniques (3.1% vs. 1.3%, p = 0.665), respectively. A patient in the TEP group developed a pseudoaneurysm and was treated with endovascular embolization.
UNASSIGNED: In our study, conversion and intraoperative early postoperative complications were more prevalent in TEP than TAPP. On the other hand, no significant difference was determined between the results of the two techniques. It has been found that TAPP is as safe as TEP in inguinal hernia surgery; however, the superiority of one method over the other was not observed in this study.

Hernia repair techniques have evolved recently; however sac handling remains a critical step. Transection of the herniated sac as opposed to total sac reduction may simplify the procedure. However, residual sac tissue may increase the risk for seroma formation. We performed a systemic review and meta-analysis to evaluate the safety and feasibility of transecting the hernia sac during laparoscopic herniorrhaphy. Relevant literature search was performed in PubMed, EMBASE, SCORPUS, and the Cochrane Library databases. Relevant studies that compared total reduction with transection of the herniated sac during laparoscopic herniorrhaphy were included. The primary outcome measure was the incidence of seromas. We also analyzed secondary outcomes including operative duration, postoperative pain scores, complications, and hernia recurrence rate. Of the 330 studies identified, four studies published between 2002 and 2020, with sample sizes ranging from 70 to 520 patients, met the inclusion criteria. Overall, 848 hernias were evaluated. We observed a high incidence of seroma formation in the sac transection group compared to that in the sac reduction group (OR 2.41; 95% CI 1.39 to 4.17, P = 0.002), but the groups did not differ significantly with respect to factor such as operative duration, postoperative complications, and pain score. Herniated sac transection during laparoscopic herniorrhaphy might be associated with a higher risk of seroma formation than that observed with sac reduction. The former approach did not show any significant benefits compared to the latter approach with respect to operative duration and postoperative complications.

UNASSIGNED: There is a dearth of studies on laparoscopic treatment of female groin hernia. Our study assessed the outcome of groin hernia repair in females employing the totally extraperitoneal laparoscopic (TEP) access.
UNASSIGNED: Data of all females who were subjected to laparoscopic groin herniorrhaphy, from August 1998 to February 2020 were retrospectively obtained. Groin hernia repair was routinely started with TEP access.
UNASSIGNED: A total of 2,399 patients who underwent laparoscopic groin herniorrhaphy, 254 (10.6%), were females. Most females (n = 191; 75.2%) had single hernia and the remaining (n = 63; 24.8%) had bilateral hernias, making a total of 317 hernias operated. Indirect inguinal hernia was the most common hernia type (72.5%), followed by femoral hernia (17.4%) and direct hernia (10.1%). Prior lower abdominal operations were recorded in 97 (38.2%) patients. Conversion to a laparoscopic transabdominal preperitoneal procedure was performed due to technical difficulties to dissect the preperitoneal space in 17 patients (6.7%) and to open procedure in only one patient (0.4%) with incarcerated femoral hernia in whom an incidental perforation of the small bowel occurred. Intra- and postoperative complications occurred in 12 (4.7%) and 15 (5.9%) patients, respectively. There was no mortality. Most patients (n = 221; 87%) were discharged on the same day of the operation. Hernia recurrence was diagnosed in 6 patients (2.4%).
UNASSIGNED: It is concluded that females with groin hernia may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.

UNASSIGNED: The influence of anesthetic method on the immune function and oxidative stress in patients receiving laparoscopic herniorrhaphy remains largely unknown.
UNASSIGNED: To assess the effects of different anesthetic methods on the immune function and oxidative stress in patients undergoing laparoscopic herniorrhaphy.
UNASSIGNED: A total of 280 eligible patients were randomly divided into two groups to receive total intravenous anesthesia (TIVA group) and inhalation anesthesia (IA group). T lymphocyte subsets, oxidative stress response indices and inflammatory factor levels were measured before anesthesia, at the end of the operation, and 1 and 3 days after the operation. The incidence rates of adverse reactions were compared.
UNASSIGNED: At the end of and 1 day after the operation, CD3+ and CD4+ T cells and CD4+/CD8+ decreased in both groups compared with those before anesthesia (p < 0.05). Three days after the operation, CD3+ and CD4+ T cells decreased in both groups compared with those before anesthesia, which were higher in the TIVA group (p < 0.05). Interleukin-6 and C-reactive protein levels were significantly lower in the TIVA group (p < 0.05). At the end of and 1 and 3 days after the operation, oxidative stress response indices superoxide dismutase, catalase and glutathione peroxidase declined in both groups compared with those before anesthesia, which were higher in the IA group (p < 0.05). The incidence rate of adverse reactions was significantly higher in the IA group (p = 0.002).
UNASSIGNED: Compared with IA, TIVA has less effect on the immune function and oxidative stress of patients undergoing laparoscopic herniorrhaphy, and controls the inflammatory response more effectively, accompanied by a lower incidence rate of adverse reactions.

BACKGROUND: Misdiagnosis or failure to intraoperatively detect occult hernia in the inguinal region can lead to the recurrence of postoperative hernia and the appearance of local pain symptoms, which affect the patient\'s quality of life and make it difficult to reperform hernia repair.
METHODS: This study included 1066 inguinal hernia patients who underwent surgical treatment at Shanghai Tongren Hospital between January 2016 and October 2018 to investigate ipsilateral occult hernia epidemiology, to analyze the characteristics of ipsilateral occult hernias with regards to patient age, gender, classification and anatomical site, and to explore the superiority and inferiority of the expert hernia surgeons/ non-expert hernia surgeons group and of operation methods in finding occult inguinal hernias.
RESULTS: The incidence of ipsilateral occult hernia in the surgical population was 8.26%. Ipsilateral occult hernia included indirect inguinal hernia, direct inguinal hernia, femoral hernia, obturator hernia, and spigelian hernia, among which the highest incidence was direct inguinal hernia (4.11%), followed by indirect inguinal hernia (2.45%). There was no difference in the incidence of ipsilateral occult hernia between males and females, but there were significant differences in the incidence of ipsilateral occult hernia, which decreased gradually with increasing age in patients younger than 70 years-old; there was no difference in incidence in patients over 70 years-old. There were significant differences in the incidence of ipsilateral occult hernia in the bilateral inguinal region between direct and femoral hernia, with the higher incidence found on the right side; in contrast, there was no difference in the incidence of indirect inguinal hernia in the bilateral inguinal region. There was no difference in the ability of experienced physicians to detect ipsilateral occult inguinal hernias, either professionally or by surgery.
CONCLUSIONS: Ipsilateral occult inguinal hernia has a higher incidence in patients with inguinal hernia, especially older patients; therefore, it is necessary for experienced surgeons to carefully detect for possible occult hernia during the operation and in elderly patients.

The use of laparoscopic surgery has become widespread in recent years. One of its complications is port site hernia (PHS). It can be difficult to close the fascia at the time of laparoscopy, especially in obese patients, and there is a risk of herniation through a fascial defect with incomplete closure. It is important to ascertain closure of the defect when repairing PHS to prevent recurrence. We report a 47-year-old woman who developed a PHS at the superior aspect of the umbilicus. We repaired the defect using the VersaOneTM Fascial Closure System with laparoscopic guidance. This system allows the port site to be reliably closed while observing the suture from the abdominal cavity. The incision is the same size as a port site. If the abdominal wall is thick and the PHS has a diameter of ~10 mm, this method is considered to be indicated, regardless of the site.

UNASSIGNED: Previous evidence indicated that total extraperitoneal (TEP) and transabdominal preperitoneal (TAPP) are advantageous in efficacy of inguinal herniorrhaphy. Therefore, our aim in this study was to evaluate the association of the two laparoscopic approaches on safety of inguinal herniorrhaphy.
UNASSIGNED: In this update study, we searched the Cochrane Library, EMBASE, PubMed, Scopus, and Web of Science and identified randomized clinical trials comparing complications in TEP and TAPP herniorrhaphy. We mainly used Peto odds ratio with 95% confidence interval (CI) for meta-analysis because of zero-cell.
UNASSIGNED: Fourteen eligible trials recruited 659 and 682 patients in TEP and TAPP respectively. In overall pooling, although TEP had a higher seroma rate than TAPP (Peto odds ratio =2.01; 95% CI, 1.39 to 2.91), it had a lower scrotal/cord edema rates at immediate postoperative (Peto odds ratio =0.22; 95% CI, 0.09 to 0.57) and 1 week after inguinal hernia repair (Peto odds ratio =0.58; 95% CI, 0.37 to 0.91) than TAPP.
UNASSIGNED: TEP and TAPP have their own advantages in inguinal herniorrhaphy. TAPP was associated with a lower seroma rate, and TEP was associated with a lower edema rate. Therefore, shared decision-making on laparoscopic inguinal herniorrhaphy with TEP and TAPP is still needed.

BACKGROUND: Port site hernias (PSH) are a potential postoperative complication in laparoscopic surgery. It is difficult to estimate their true incidence given the descrepancy in published reports.
METHODS: This is a case report of a 42-year-old lady who developed two separate PSH requiring a laparoscopic repair. This is also the first reported case of multiple PSH in a single patient in the English literature.
CONCLUSIONS: This report highlights the need for further research in establishing well defined incidence rates in order to properly discuss future surgical risks when consenting a patient for laparoscopic surgery. It is our belief that future research should be directed towards determining the risk associated with different trocar types, in the setting of various premorbid patient factors, to help surgeons decide on relevant instrument use and the most appropriate closure for port sites.
CONCLUSIONS: The growing incidence of PSH has brought about significant changes in the practice of laparoscopic surgery which behoves us as practicing clinicians to stay abreast of these changes so as to decrease the incidence of PSH.
