A prospective randomised control trial to compare the perioperative outcomes and ergonomic challenges between triangular versus midline port placement in total extra-peritoneal repair of uncomplicated unilateral inguinal hernia.

BACKGROUND: Routine TEP technique requires three skin incisions for placement of three trocars in the midline. Otherwise, this can be done by three-port triangular technique or two-hand technique. This study reports a randomised trial of perioperative outcomes and ergonomics characteristics of this procedure using two different techniques of port insertion. METHODS: N = 28 patients were randomised into two groups for triangular three-port (TTEP) versus midline three-port TEP (MTEP) hernioplasty after informed written consent in Department of Surgery, King George's Medical University UP between September 2016 and September 2017 after institutional ethical approval. Patient-related outcomes in terms of quality of life (QOL) and ergonomic evaluation of the technique were compared in double-blinded fashion. RESULTS: Postoperative pain score at 24 h post surgery (5.1 ± 0.6; 95% CI 4.9-5.3 vs. 4.8 ± 0.4; 95% CI 4.6-4.9) differed, while hospital stay, time to return to routine work, tolerance to oral feeds and intraoperative complications occurrence (OR 2.1; 95% CI 0.2-24.3) were comparable in both groups. Time to return to office work (5.5 ± 0.5; 95% CI 5.4-5.7 vs. 4.0 ± 0.8; 95% CI 3.7-4.3) and immediate postoperative sensation of mesh and pain score were significantly higher in MTEP compared to TTEP. Ergonomic parameters including visualization of landmark score, spreading of mesh score and total surgeon satisfaction score (TTEP 8.4 ± 0.7; 95% CI 8.1-8.6 vs. MTEP 7.0 ± 0.8; 95% CI 6.7-7.3), mental effort quotient (SMEQ score: TTEP 50.6 ± 12.7; 95% CI 45.9-55.3 vs. MTEP 70.8 ± 12.6: 95% CI 66.1-75.4) and physical effort quotient (LEDQ scores in wrist, hand, arm and shoulders) were also superior in triangular technique of port placement. CONCLUSION: Triangular three-port TEP hernioplasty is ergonomically feasible and enables a surgeon to perform surgery safely using basic principles of laparoscopy.

Senior General Surgery Resident Confidence in Performing Abdominal Wall Hernia Repairs.

BACKGROUND: It is expected that graduating general surgery residents be confident in performing common abdominal wall hernia repairs. The objective of our study was to assess the confidence of senior surgical residents in these procedures and to identify factors that correlate with confidence. METHODS: We performed a cross-sectional survey of PGY-4 and PGY-5 general surgery residents at ACGME-accredited programs in the United States in the spring of 2019. Respondents rated their confidence level in 12 hernia procedures on a Likert scale from 1 (not confident) to 5 (extremely confident). Respondents were classified as "Not Confident" (Not Confident, Minimally Confident, Neutral responses) or "Confident" (Confident, Extremely Confident responses). Resident characteristics, program characteristics, and operative experience were collected, and we calculated the area under the curve to screen which factors discriminated between those confident versus not. Multivariable Poisson regression was used to estimate prevalence ratios (PR) and 95% confidence intervals (CI) to identify which factors were most predictive. RESULTS: A total of 93 surveys were completed. Respondents reported low confidence rates (25%-60%) in the following hernia repairs: minimally invasive (MIS) inguinal, femoral, tissue (nonmesh) inguinal, pediatric inguinal, and abdominal wall reconstruction. High confidence rates (>80%) were reported for open umbilical, open ventral, and MIS ventral hernia repairs. For MIS inguinal hernia repair, PGY-5 level was associated with a twofold increase in confidence (PR = 2.01; 95% CI = 1.34-3.30), and dedicated research years were associated with low confidence (PR = 0.67; 95% CI = 0.43-1.04). In general, higher operative volumes of a specific repair were associated with increased confidence in that procedure. CONCLUSIONS: Senior surgical residents reported low confidence in performing a variety of essential hernia repairs (particularly MIS inguinal, femoral, and tissue inguinal). Addressing factors associated with low confidence may help increase resident confidence.

The impact of internet-based patient self-education of surgical mesh on patient attitudes and healthcare decisions prior to hernia surgery.

BACKGROUND: As internet access improves, patient self-education continues to increase. However, patient surgical background, e-literacy, and media exposure potentially influence what information patients search online. This impacts patient concern, healthcare decisions, and subsequent patient-physician interactions. The purpose of this pilot study is to characterize hernia patients' use and the impact of internet self-education regarding surgical mesh. METHODS: The target population included patients presenting for evaluation of hernia repair with mesh. A total of 30 patients were enrolled. Patients took surveys before and after the initial surgical consult. The surveys evaluated internet use, mesh research completed, the impact on patient opinions/decisions, and the impact of research on the patient-physician interaction. RESULTS: The average age of the patients was 58.7 years; sixteen had prior surgery with surgical mesh. 93% of patients were aware of surgical mesh through the media, and 60% were motivated by the media to conduct research. 90% of patients conducted research, and 67% used the internet. Patients with negative attitudes toward mesh had more media exposure in comparison to those with neutral or positive attitudes (p = 0.046), and they were more likely to have researched surgical mesh because of media influence (p = 0.033). This group had the highest rate of perceived knowledge on mesh risks and the lowest regarding benefits (p = 0.013). Patients who had prior surgery without complication had the most positive attitude toward surgical mesh (p = 0.010) and were less likely to plan to do future internet research (p = 0.041) in comparison to patients who had surgery with complications or no prior surgery. CONCLUSIONS: Patients' attitudes and perceived knowledge regarding surgical mesh are associated with media exposure and internet research. These attributes along with prior surgical experience impact the patient-physician relationship and shared decision-making model regarding patient care.

Surgical Consultation as Social Process: Implications for Shared Decision Making.

OBJECTIVE: This qualitative study examines surgical consultation as a social process and assesses its alignment with assumptions of the shared decision-making (SDM) model. SUMMARY OF BACKGROUND DATA: SDM stresses the importance of patient preferences and rigorous discussion of therapeutic risks/benefits based on these preferences. However, empirical studies have highlighted discrepancies between SDM and realities of surgical decision making. Qualitative research can inform understanding of the decision-making process and allow for granular assessment of the nature and causes of these discrepancies. METHODS: We observed consultations between 3 general surgeons and 45 patients considering undergoing 1 of 2 preference-sensitive elective operations: (1) hernia repair, or (2) cholecystectomy. These patients and surgeons also participated in semi-structured interviews. RESULTS: By the time of the consultation, patients and surgeons were predisposed toward certain decisions by preceding events occurring elsewhere. During the visit, surgeons had differential ability to arbitrate surgical intervention and construct the severity of patients' conditions. These upstream dynamics frequently displaced the centrality of the risk/benefit-based consent discussion. CONCLUSION: The influence of events preceding consultation suggests that decision-making models should account for broader spatiotemporal spans. Given surgeons' authority to define patients' conditions and control service provision, SDM may be premised on an overestimation of patients' power to alter the course of decision making once in a specialist's office. Considering the subordinate role of the risk/benefit discussion in many surgical decisions, it will be important to study if and how the social process of decision making is altered by SDM-oriented decision aids that foreground this discussion.

The Prevalence and Characteristics of Untreated Hernias in Southwest Cameroon.

BACKGROUND: Hernias are one of the most commonly encountered surgical conditions, and every year, more than 20 million hernia repairs are performed worldwide. The surgical management of hernia, however, is largely neglected as a public health priority in developing countries, despite its cost-effectiveness. To date, the prevalence and impact of hernia have not been formally studied in a community setting in Cameroon. The aim of this study was to determine the prevalence and characteristics of untreated hernia in the Southwest region of Cameroon. METHODS: This study was a subanalysis of a cross-sectional community-based survey on injury in Southwest Cameroon. Households were sampled using a three-stage cluster sampling method. Household representatives reported all untreated hernias occurring in the past year. Data on socioeconomic factors, hernia symptoms, including the presence of hernia incarceration, and treatment attempts were collected between January 2017 and March 2017. RESULTS: Among 8065 participants, 73 persons reported symptoms of untreated hernia, resulting in an overall prevalence of 7.4 cases per 1000 persons (95% confidence limit 4.98-11.11). Groin hernias were most commonly reported (n = 49, 67.1%) and predominant in young adult males. More than half of persons with untreated hernia (56.7%) reported having symptoms of incarceration, yet 42.1% (n = 16) of these participants did not receive any surgical treatment. Moreover, 21.9% of participants with untreated hernias never presented to formal medical care, primarily because of the high-perceived cost of care. Untreated hernias caused considerable disability, as 21.9% of participants were unable to work because of their symptoms, and 15.1% of households earned less money. CONCLUSIONS: Hernia is a significant surgical problem in Southwest Cameroon. Despite over half of those with unrepaired hernias reporting symptoms of incarceration, home treatment and nonsurgical management were common. Costs associated with formal medical services are a major barrier to obtaining consultation and repair. Greater awareness of hernia complications and cost restructuring should be considered to prevent disability and mortality due to hernia.

Emergency inguinal hernioplasties in a tertiary public Hospital in Athens Greece, during the economic crisis.

BACKGROUND: Although the effect of the recent Greek economic crisis and austerity on the population's health and the health system effectiveness have been discussed a lot recently, data on common surgical conditions affecting large part of the population are missing. Using inguinal hernia as a model we investigated possible changes of citizens' attitude regarding the time of referral, the perioperative details and the intraoperative findings of the emergency hernioplasties. METHODS: The present retrospective study was conducted by a Department of Surgery in a tertiary public hospital of the Greek capital. We reviewed the records of all hernioplasties performed during two 5-year periods: 2005-2009 and 2012-2016, i.e. before and during the crisis focusing on the emergency ones (either incarcerated or strangulated). RESULTS: An equal number of hernioplasties was performed in both periods. During the crisis however, an emergency hernioplasty was significantly more probable (HR 1.269, 95% CI 1.108-1.1454, p = 0.001), at a younger age (p = 0.04), mainly in patients younger than 75 years old (p = 0.0013). More patients presented with intestinal ischemia (7 vs 18, p = 0.002), requiring longer hospitalization (5.2 vs 9.6 days, p = 0.04), with higher cost (560 ± 262.4€ vs 2125 ± 1180.8€ p < 0.001). In contrast the percentage of patients with intestinal resection, their hospitalization length and treatment-cost remained unchanged. During the crisis there was a non-significant increase of emergency patients requiring ICU postoperatively (0 vs 4, p = 0.07) and a non-significant 60% increase of emergency operations in migrants/refugees population (3.5% vs 5.8%, p = 0.28). Epidural anesthesia was significantly more frequent during the crisis. CONCLUSION: During the crisis: (i) the emergency hernioplasties increased significantly, (ii) more patients (exclusively Greek) presented with intestinal ischemia requiring longer hospitalization and higher treatment cost, (iii) the mean age of the urgently treated patients decreased significantly (iv) regional (epidural) anesthesia was more frequent. Although a direct causal relation could not be proven by the present study most observations can be explained by an increase of the patients who delayed the elective treatment of their hernia, and by a redistribution of the surgical workload towards big central hospitals. This can be prevented by adequately supporting the small district hospitals.

Effect of Preoperative Visitation by Operating Room Staff on Preoperative Anxiety in Patients Receiving Elective Hernia Surgery.

PURPOSE: The purpose of this study was to evaluate the effect of preoperative visitation on preoperative anxiety in patients receiving elective hernia surgery. DESIGN: Quasi-experimental study. METHODS: Seventy patients undergoing hernia surgery were selected and assigned to the experimental group (N = 35) and the control group (N = 35). In the intervention group, the surgical technologist visited the patient in the surgical ward the night before surgery and after transferring the patient to the waiting room in the operating room department. The control group received only routine preoperative care by nurses in the surgical ward and operating room department. For both groups, the Spielberger State-Trait Anxiety Inventory was completed in two stages, on the night before surgery and on arrival time in the operating room. FINDINGS: Average age was 41.2 ± 13.4 years. Statistical tests showed a significant reduction in anxiety after intervention (42.3 ± 9.2) compared with before intervention (45.6 ± 9) and between the two groups after intervention (50.9 ± 10.7 in the control group vs 42.3 ± 9.2 in the intervention group). CONCLUSIONS: Using an anxiety evaluation approach in preoperative training programs to manage anxiety in surgical patients is recommended.

Association between psychological health and wound complications after surgery.

BACKGROUND: Surgical wound complications remain a major cause of morbidity, leading to higher costs and reduced quality of life. Although psychological health is widely considered to affect wound healing, the evidence on wound outcomes after surgery is mixed. Studies generally focus on small samples of patients undergoing a specific procedure and have limited statistical power. METHODS: This study investigated the relationship between three different measures of anxiety and/or depression and seven adverse surgical outcomes using observational data collected before and after surgery between 2009 and 2011. A wide range of confounding factors was adjusted for, including patient demographics, physical co-morbidities, health-related behaviours, month of operation, procedure complexity and treating hospital. RESULTS: The estimation sample included 176 827 patients undergoing 59 410 hip replacements, 64 145 knee replacements, 38 328 hernia repairs and 14 944 varicose vein operations. Patients with moderate anxiety or depression had an increased probability of wound complications after a hip replacement (odds ratio (OR) 1·17, 95 per cent c.i. 1·11 to 1·24). They were more likely to be readmitted for a wound complication (OR 1·20, 1·02 to 1·41) and had an increased duration of hospital stay by 0·19 (95 per cent c.i. 0·15 to 0·24) days. Estimated associations were consistent across all four types of operation and for each measure of anxiety and/or depression. CONCLUSION: Preoperative psychological health is a significant risk factor for adverse wound outcomes after surgery for four of the procedures most commonly performed in England.

Impact of Preoperative Anxiety in Patients on Hemodynamic Changes and a Dose of Anesthetic During Induction of Anesthesia.

OBJECTIVES: Each surgical patient is preoperatively, intraoperatively and postoperatively exposed to stress. The aim of this study was to determine the existence of preoperative anxiety, and to determine its impact on hemodynamic parameters (blood pressure, heart rate) in patients and dose of anesthetics during induction of anesthesia. METHODS: A prospective clinical study conducted at the Department of Anesthesiology and Reanimation and Surgery Clinic of University Clinical Center Tuzla (UCC) in the period May 2012. to January 2015. The 80 patients were analyzed which were planned for and done an elective cholecystectomy surgery or herniectomy surgical intervention. Preoperative anxiety was measured with the help of Spielberg test and evaluation of depth of anesthesia was performed with BIS monitoring. RESULTS: The results showed that all patients had some degree of preoperative manifest anxiety. Average values of mean arterial pressure, preoperatively and after the induction of general anesthesia, differed for 15,4 mm/Hg, but were not observed significant association between Spielberg score and differences in blood pressure. Preoperative anxiety is a significant predictor of administered dose of anesthetic. Each additional score on Spielberg scale reduces the dose of anesthetic for 0,304 mg/kgTT. CONCLUSION: Adequate assessment of preoperative anxiety and undertaking of certain steps to reduce it can assist in accurately determining the required dosage of anesthetic for the introduction of general anesthesia.

Health-related quality of life after TAPP repair for the sportsmen's groin.

BACKGROUND: Sportsmen's groin (SG) is a clinical diagnosis of chronic, painful musculotendinous injury to the medial inguinal floor in the absence of a groin hernia. Long-term results for laparoscopic inguinal hernia repair, especially data on health-related quality of life (HRQOL), are scant and there are no available data whatsoever on HRQOL after SG. The main goal of this study was to compare postoperative QOL data in the long term after transabdominal preperitoneal hernioplasty (TAPP) in groin hernia and SG patients with QOL data of a normal population. METHODS: This study included all patients (n = 559) who underwent TAPP repair between 2000 and 2005. Forty seven patients (8.4 %) were operated on for SG. We sent out the Short Form 36 Health Survey (SF-36) questionnaire for QOL evaluation. QOL data were compared with data from an age- and sex-matched normal population. RESULTS: Ultimately, 383 completed questionnaires were available for evaluation (69 % response rate). The mean follow-up time was 94 ± 20 months. In the SG group there were statistically significant differences in three subscales of the SF-36 and the mental component summary measure, showing better results for the SG group compared to the sex- and age-matched normal group data. There were no statistically significant differences between groin hernia patients and the sex- and age-matched normal population. CONCLUSION: TAPP repair for SG as well as groin hernia results in good HRQOL in the long term. Results for SG patients are comparable with QOL data of a normal population or even better.

[The remote results of treatment of patients with postoperative abdominal hernias depending on surgical access].

The modern concept of life quality research in herniology is applied in the work. 202 patients with postoperative abdominal hernias who underwent making a prosthetic appliance hernioplasties for the period from 2000 to 2010 were included in the study. 105 patients (studied group) and 97 patients were operated by using of laparoscopic and conventional techniques, respectively. Quality of life was evaluated by using of standardized russified questionnaire SF-36 which allowed to make idea about two main components of health - physical and mental. Laparoscopic plasty has certain advantages in comparison with conventional techniques. Also it increases quality of life of patients in terms more than 1 year after surgery.

Prospective study of pain, quality of life and the economic impact of open inguinal hernia repair.

BACKGROUND: There are variations in quality of life (QoL) and reported risk of chronic pain after inguinal hernia repair. The aim of this study was to investigate the improvement in pain and QoL after open inguinal hernia repair, and the economic impact. METHODS: Patients undergoing open mesh repair of a primary unilateral inguinal hernia were stratified depending on preoperative levels of symptoms and pain. Short Form 36 (SF-36®) and EQ-5D™ questionnaires were filled in before, and at 3 and 12 months after surgery. EQ-5D™ data, together with information on the mean value of a quality-adjusted life-year and the societal cost of hernia repair, were used to calculate the monetary value of QoL gained and the mean return on investment. RESULTS: Of 225 patients who began the study, 184 completed follow-up at 12 months. Some 77·2 per cent reported improvement in pain and 5·4 per cent reported increased pain after surgery. Significant improvement in SF-36® scores, pain scores measured on a visual analogue scale (VAS), and symptoms were found in the majority of patients, even those with mild symptoms before surgery. For the whole group, the bodily pain score increased from 56·4 before surgery to 82·6 at 12 months after hernia repair (P < 0·050), and the VAS score decreased from a median of 4 to 0 (P < 0·050). The return on investment was positive for all groups of patients, including those with mild symptoms. CONCLUSION: QoL improves after open inguinal hernia repair, with a good return on investment independent of symptom severity.

Unilateral inguinal hernia: laparoscopic or inguinal approach. Decision making strategy: a prospective study.

The management of the contralateral region in a child with a known unilateral inguinal hernia is a debated issue among paediatric surgeons. The available literature indicates that the perspective of the child's parents is seldom. This study was performed to evaluate parents' views on this topic. After the Ethical Committee's approval, 100 consecutive patients under 12 years of age with a unilateral inguinal hernia were studied prospectively from March 2010 to September 2010. After an oral interview, a study form was given to the parents about the nature of an inguinal hernia, the incidence of 20 to 90% of a contralateral patency of the peritoneal-vaginal duct and the possible surgical options (inguinal repair or laparoscopic repair). The parents' decision and surgical results were analyzed. Eighty-nine parents chose laparoscopic approach, and 11 parents preferred inguinal exploration. Regarding their motives, all 89 parents requesting laparoscopic approach indicated that the convenience and risk to have a second anaesthesia was the primary reason of their decision. The 11 parents who preferred inguinal approach indicated that the fear of a new surgical technology was their primary reason. Conclusion There is no consensus about the management of paediatric patients with a unilateral inguinal hernia. We believe that a correct decision-making strategy for parents' choice is to propose them the both procedures. Our study shows that parents prefer laparoscopic inspection and repair in the vast majority of cases.

Long term outcome and quality of life after open incisional hernia repair--light versus heavy weight meshes.

BACKGROUND: Mesh repair of incisional hernia is superior to the conventional technique. From all available materials for open surgery polypropylene (PP) is the most widely used. Development resulted in meshes with larger pore size, decreased mesh surface and lower weight. The aim of this retrospective non randomized study was to compare the quality of life in the long term follow up (> 72 month) after incisional hernia repair with "light weight"(LW) and "heavy weight"(HW) PP meshes. METHODS: 12 patients who underwent midline open incisional hernia repair with a HW-PP mesh (Prolene® 109 g/m2 pore size 1.6 mm) between January 1996 and December 1997 were compared with 12 consecutive patients who underwent the same procedure with a LW-PP mesh (Vypro® 54 g/m2, pore size 4-5 mm) from January 1998. The standard technique was the sublay mesh-plasty with the retromuscular positioning of the mesh. The two groups were equal in BMI, age, gender and hernia size. Patients were routinely seen back in the clinic. RESULTS: In the long term run (mean follow up 112 ± 22 months) patients of the HW mesh group revealed no significant difference in the SF-36 Health Survey domains compared to the LW group (mean follow up 75 ± 16 months). CONCLUSIONS: In this study the health related quality of life based on the SF 36 survey after open incisional hernia repair with light or heavy weight meshes is not related to the mesh type in the long term follow up.

Patient quality of life before and after ventral hernia repair.

BACKGROUND: Recurrence is often reported as the primary outcome among studies of patients with hernias; however, there is growing interest in patient quality of life. The relationship between quality of life and recurrence is poorly understood. This study evaluates this relationship. METHODS: A secondary analysis of 3 prospective clinical trials was performed. The modified Activities Assessment Scale, a validated, abdominal wall-specific quality of life tool was used (1 = poor quality of life and 100 = perfect quality of life). Patients with and without a hernia recurrence were compared. Baseline quality of life, follow-up quality of life, and change in quality of life were measured. The relationship between quality of life and clinical outcomes was examined. RESULTS: A total of 238 patients were followed for median (range) 30 (14-44) months, of whom 31 (13.0%) had a clinical recurrence, whereas 207 (87.0%) had no clinical recurrence. Patients with recurrence were more likely to have a lower mean baseline quality of life (14 vs 26; P = .035), follow-up quality of life (42 vs 82; P < .001), and change in quality of life (19 vs 33; P < .018). The majority of patients with or without recurrence still experienced an improvement in quality of life (68% vs 79%; P = .142). CONCLUSION: Patients with lower baseline quality of life are likely to experience a recurrence following repair; however, most still report substantial improvements in quality of life. Assessing follow-up quality of life without accounting for baseline quality of life is incomplete; follow-up quality of life should be assessed with appropriate adjustment for baseline quality of life.

The Effect of an Interval Training on Skill Retention of High-Complex Low-Volume Minimal Invasive Pediatric Surgery Skills: A Pilot Study.

Background: Current training programs for complex pediatric minimal invasive surgery (MIS) are usually bulk training, consisting of 1- or 2-day courses. The aim of this study was to examine the effects of bulk training versus interval training on the preservation of high-complex, low-volume MIS skills. Materials and Methods: Medical students, without prior surgical experience, were randomly assigned to either a bulk or interval training program for complex MIS (congenital diaphragmatic hernia [CDH] and esophageal atresia [EA] repair). Both groups trained for 5 hours; the bulk group twice within 3 days and the interval groups five times in 3 weeks. Skills retention was assessed at 2 weeks, 6 weeks, and 6 months posttraining, using a composite score (0%-100%) based on the objective parameters tracked by SurgTrac. Results: Seventeen students completed the training sessions (bulk n = 9, interval n = 8) and were assessed accordingly. Retention of the skills for EA repair was significantly better for the interval training group than for the bulk group at 6 weeks (P = .004). However, at 6 months, both groups scored significantly worse than after the training sessions for EA repair (bulk 60 versus 67, P = .176; interval 63 versus 74, P = .028) and CDH repair (bulk 32 versus 67, P = .018; interval 47 versus 62, P = .176). Conclusion: This pilot study suggests superior retention of complex pediatric MIS skills after interval training, during a longer period of time, than bulk training. However, after 6 months, both groups scored significantly worse than after their training, indicating the need for continuous training.

#Mesh: Social Media and Its Influence on Perceptions in Hernia Repair.

Social media can influence public perception in health care. By 2016, social media discussion against the use of transvaginal mesh influenced changes in Food and Drug Administration (FDA) regulations. We propose that the fate of hernia mesh will follow that of transvaginal mesh. Thus, we compare the trend of social media discussion of hernia and transvaginal mesh. Posts on Twitter and public Facebook groups were tracked for keywords "hernia," "hernia mesh," and "pelvic/vaginal mesh." Posts were categorized based on sentiment. On Facebook, 16 public groups with 14 526 members expressed negative sentiments in 95% of their 750 daily posts. Meanwhile, of the 1.1 million tweets on Twitter, those about hernia mesh were more negative (36.5%) than those about pelvic/vaginal mesh (29.2%). Three of the 5 top tweeters about hernia mesh and pelvic/vaginal mesh were linked to law firms involved in mesh-based lawsuits. The negative sentiments and steering of social media discussion by lawyers may directly affect surgical care. As surgeons, we may adapt our informed consent to acknowledge our patients' apprehensions about mesh. We may also be more involved in social media discussions ourselves. Meanwhile, we await FDA decisions in the regulation and availability of hernia mesh.

Robotic inguinal hernia repair: is technology taking over? Systematic review and meta-analysis.

PURPOSE: To examine the current evidence on the therapeutic role and outcomes of robotic Transabdominal Preperitoneal Inguinal hernia repair (rTAPP) to better define its risk-benefit ratio and guide clinical decision-making. METHODS: PubMed, EMBASE, and Web of Science were consulted. A Frequentist single-arm study-level random effect meta-analysis was performed. RESULTS: Twelve studies published between 2015 and 2018 met the inclusion criteria (1645 patients). Patients' age ranged from 16 to 96, the BMI ranged from 19 to 35.6 kg/m2, and 86.1% were males. Unilateral hernia repair was performed in 69.6% while bilateral hernia repair was performed in 30.4% of patients. The operations were all conducted using the da Vinci Xi or Si robotic system (Intuitive Surgical, Inc., Sunnyvale, CA, USA). The rTAPP was successfully completed in 99.4% of patients and the operative time ranged from 45 to 180.4 min. The postoperative follow-up ranged from 16 to 368 days. The estimated pooled prevalence of intraoperative complications and conversion were 0.03% (95% CI 0.00-0.3) and 0.14% (95% CI 0.0-0.5%), respectively. The estimated pooled prevalence of urinary retention, seroma/hematoma, and overall complications were 3.5% (95% CI 1.6-5.8%), 4.1% (95% CI 1.6-7.5%), and 7.4% (95% CI 3.4-10.9%). The estimated pooled prevalence of hernia recurrence was 0.18% (95% CI 0.00-0.84%). CONCLUSIONS: Robotic technology has been progressively entering surgical thinking and gradually changing surgical procedures. Based on the results of the present study, the rTAPP seems feasible, safe, and effective in the short term for patients with unilateral and bilateral inguinal hernias. Further prospective studies and randomized controlled trials are needed to validate these findings.

Prevalence of posttraumatic stress disorder (PTSD) in patients with an incisional hernia.

BACKGROUND: We investigate the prevalence of PTSD in patients with an incisional hernia presenting for evaluation at our institution. METHODS: Study patients were screened for PTSD using the PCL-5 checklist for DSM-5. Patient-reported quality of life and pain scores were assessed using validated tools (HerQLes and PROMIS Pain Intensity 3a survey). RESULTS: The prevalence of PTSD in 131 patients was 32.1% [95% CI 24%-40%]. Patients screening positive (PTSD+) reported lower quality of life scores on HerQles (17.3 ± 14.3 vs. 47.7 ± 29.6, P < 0.001), and higher pain scores on the PROMIS scale (54.2 ± 9.1 vs. 44.2 ± 10, p < 0.001). PTSD + patients also reported significantly higher numbers of previous hernia repairs and abdominal operations, as well as a higher rate of a history of an open abdomen. CONCLUSION: Our study found a significant prevalence of positive screening for PTSD in patients seeking consultation regarding an incisional hernia. We have begun routine preoperative evaluations by a behavioral medicine specialist to address some of these complex issues in high-risk patients. Other high volume hernia programs caring for this challenging patient population should consider such assessments.

The impact of preoperative anxiety, depression, and chronic pain on outcomes in abdominal wall reconstruction.

PURPOSE: An association of anxiety with surgical outcomes has been suggested, including with open ventral hernia repair (OVHR). This study examines the interaction of multiple comorbidities, including anxiety, depression, chronic pain, and hernia characteristics with outcomes after OVHR. METHODS: Patients with anxiety were identified in an existing, prospectively collected, data set of OVHR with preoperative work-up including CT scans (2007-2018). A patient with a diagnosis or prescription for anxiolytics, anti-depressants, or narcotics was considered to have anxiety, depression, or chronic pain, respectively. Hernia characteristics were analyzed using 3D volumetric software. Univariate and multivariate analyses were performed to assess for the impact of anxiety on surgical outcomes. RESULTS: A total of 1178 OVHRs were identified. The diagnosis of anxiety (23.9%) was associated with female gender (29.1% females vs. 16.9% males, p = 0.002), depression (56.7 vs. 18.8%, p < 0.0001), preoperative chronic pain (43.6 vs. 26.9%, p < 0.0001), COPD, arrhythmia, history of MRSA, and sleep apnea (p ≤ 0.05 all values). Patients with anxiety had larger hernia volume and defect size, and were more likely to undergo component separation, with higher rates of wound complication and intervention for pain (p ≤ 0.05 all values). After multivariate analysis controlling for multiple potentially confounding factors, the comorbidities of anxiety, depression, and preoperative chronic pain were not found to be significantly associated with adverse outcomes. CONCLUSIONS: The diagnosis of anxiety is associated with preoperative comorbidity, surgical complexity, and adverse outcomes after OVHR. However, when comorbidities are controlled for, the diagnosis of anxiety, depression or preoperative pain does not independently predict adverse outcomes. In this context, anxiety may be considered a marker of patient comorbidity in a complex patient population.
