RESUMEN
BACKGROUND: Implementing a robotic system for minimally invasive surgical procedures necessitates a comprehensive training regimen. This involves not only mastering the technological aspects of the robotic system but also enhancing surgical proficiency in manipulating robotic instruments. Furthermore, procedural expertise in specific surgeries is critical. Minimally invasive inguinal hernia repair is particularly suitable as an initial procedure for human application. The development of a comprehensive training model for this type of repair is a crucial element of such an educational pathway. METHOD: Anatomical dissections were carried out on pigs to assess both the similarities and differences between pig and human anatomy. A structured minimally invasive inguinal hernia repair was performed to determine the suitability of the porcine inguinal region for training purposes. RESULTS: A detailed anatomical description of the porcine inguinal region is outlined, to provide a framework for assessing the critical view of the porcine myopectineal orifice. By integrating the human 'ten golden rules' for safe and effective minimally invasive inguinal hernia repair, the standardized porcine integrated robotic inguinal hernia training (SPIRIT) model describes a step-by-step approach to practice surgical techniques in a realistic setting. CONCLUSION: The SPIRIT model is designed to be a well-structured training model for minimally invasive inguinal hernia repair and incorporates the specific surgical steps as encountered in a human patient.

BACKGROUND: Transversus abdominis release (TAR) is an effective technique for treating large midline and off-midline hernias. Recent studies have demonstrated that robotic TAR (rTAR) is technically feasible and associated with improved outcomes compared to open surgery. There is no published experience to date describing abdominal wall reconstruction using the novel robotic platform HUGO RAS System (Medtronic®). METHODS: All consecutive patients who underwent a rTAR in our institution were included. Three of the four arm carts of the HUGO RAS System were used at any given time. Each arm configuration was defined by our team in conjunction with Medtronic® personnel. rTAR was performed as previously described. Upon completion of the TAR on one side, a redocking process with different, mirrored arms angles was performed to continue with the contralateral TAR. Operative variables and early morbidity were recorded. RESULTS: Ten patients were included in this study. The median BMI was 31 (21-40.6) kg/m2. The median height was 1.6 m (1.5-1.89 m). A trend of decreased operative time, console time, and redocking time was seen in these consecutive cases. No intraoperative events nor postoperative morbidity was reported. The median length of stay was 3 (1-6) days. CONCLUSION: Robotic TAR utilizing the HUGO RAS system is a feasible and safe procedure. The adoption of this procedure on this novel platform for the treatment of complex abdominal wall hernias has been successful for our team.

BACKGROUND: The surgical management of midline ventral hernias complicated by concomitant diastasis recti presents a significant clinical challenge. The Endoscopic Onlay Repair (ENDOR) offers a minimally invasive solution, effectively addressing both conditions. This study focuses on describing the adaptation of ENDOR to a robotic platform, termed R-ENDOR, aiming to report initial outcomes along with other established robotic surgical approaches. METHODS: This retrospective case series study included consecutive adult patients who underwent R-ENDOR approach from October 2018 to April 2023, performed by a single surgeon. A comprehensive description of the surgical technique is included. Patient demographics, operative, and hernia-specific characteristics, as well as clinical outcomes are described. RESULTS: A total of 15 patients undergoing R-ENDOR for ventral hernia repair with diastasis recti plication were included. The median age was 59 years (IQR 42-63), with 60% (n = 9) female patients. The majority (86%, n = 13) had an ASA score of ≤ 2, and the median BMI was 24 kg/m2, with 20% (n = 3) classified as obese. Median hernia size was 2 cm (IQR 2-2.25), with a median diastasis length of 19 cm (IQR 15-21.5) and width of 4 cm (IQR 3-6). The median operative time was 129 min (IQR 113-166). Most repairs (93%, n = 14) were reinforced with mesh, predominantly self-fixating (73.3%, n = 11). Eighty percent of patients (n = 12) were discharged on the same day, with a median follow-up of 153 days (IQR 55-309). Notable complications included clinically significant seromas in 20% of patients (n = 3), long-term hypoesthesia in 40% (n = 6), and readmission in one patient (6.6%) for surgical site infection (SSI) requiring IV antibiotic therapy. CONCLUSION: Midline ventral hernias associated to diastasis recti can be managed robotically by ENDOR with safe and consistent 90-day outcomes in a carefully selected group of patients.

BACKGROUND: Surgical videos coupled with structured assessments enable surgical training programs to provide independent competency evaluations and align with the American Board of Surgery's entrustable professional activities initiative. Existing assessment instruments for minimally invasive inguinal hernia repair (IHR) have limitations with regards to reliability, validity, and usability. A cross-sectional study of six surgeons using a novel objective, procedure-specific, 8-item competency assessment for minimally invasive inguinal hernia repair (IHR-OPSA) was performed to assess inter-rater reliability using a "safe" vs. "unsafe" scoring rubric. METHODS: The IHR-OPSA was developed by three expert IHR surgeons, field tested with five IHR surgeons, and revised based upon feedback. The final instrument included: (1) incision/port placement; (2) dissection of peritoneal flap (TAPP) or dissection of peritoneal flap (TEP); (3) exposure; (4) reducing the sac; (5) full dissection of the myopectineal orifice; (6) mesh insertion; (7) mesh fixation; and (8) operation flow. The IHR-OPSA was applied by six expert IHR surgeons to 20 IHR surgical videos selected to include a spectrum of hernia procedures (15 laparoscopic, 5 robotic), anatomy (14 indirect, 5 direct, 1 femoral), and Global Case Difficulty (easy, average, hard). Inter-rater reliability was assessed against Gwet's AC2. RESULTS: The IHR-OPSA inter-rater reliability was good to excellent, ranging from 0.65 to 0.97 across the eight items. Assessments of robotic procedures had higher reliability with near perfect agreement for 7 of 8 items. In general, assessments of easier cases had higher levels of agreement than harder cases. CONCLUSIONS: A novel 8-item minimally invasive IHR assessment tool was developed and tested for inter-rater reliability using a "safe" vs. "unsafe" rating system with promising results. To promote instrument validity the IHR-OPSA was designed and evaluated within the context of intended use with iterative engagement with experts and testing of constructs against real-world operative videos.

BACKGROUND: Open inguinal hernia repair is the most commonly performed procedure in general surgery in sub-Saharan Africa, but data on its learning curve are lacking. This study evaluated the learning curve characteristics to improve surgical training and enable scaling up hernia surgery in low- and middle-income countries. METHODS: Logbook data of associate clinicians enrolled in a surgical training program in Sierra Leone were collected and their first 55 hernia surgeries following the Bassini technique (herniorrhaphies) were analyzed in cohorts of five cases. Studied variables were gradient of decline of operating time, variation in operating time, and length of stay (LOS). Eleven subsequent cohorts of each five herniorrhaphies were investigated. RESULTS: Seventy-five trainees enrolled in the training program between 2011 and 2020 were eligible for inclusion. Thirty-one (41.3%) performed the minimum of 55 herniorrhaphies, and had also complete personal logbook data. Mean operating times dropped from 79.6 (95% CI 75.3-84.0) to 48.6 (95% CI 44.3-52.9) minutes between the first and last cohort, while standard deviation in operating time nearly halved to 15.4 (95% CI 11.7-20.0) minutes, and LOS was shortened by 3 days (8.5 days, 95%CI 6.1-10.8 vs. 5.4 days, 95% 3.1-7.6). Operating times flattened after 31-35 cases which corresponded with 1.5 years of training. CONCLUSIONS: The learning curve of inguinal hernia surgery for associate clinicians flattens after 31-35 procedures. Training programs can be tailored based on this finding. The recorded learning curve may serve as a baseline for future training techniques.

BACKGROUND: Prophylactic intra-abdominal onlay mesh (IPOM) implantation has been shown to reduce the rate of fascial dehiscence and incisional hernia. However, surgical site infection (SSI) in presence of an IPOM remains a concern. The aim of this study was to assess predictors for SSI following IPOM placement in hernia and non-hernia abdominal surgery in clean and contaminated surgical fields. METHODS: Observational study including patients undergoing IPOM placement at a Swiss tertiary care hospital 2007-2016. IPOM implantation was performed in hernia and non-hernia elective and emergency abdominal surgery, including contaminated and infected surgical fields. The incidence of SSI was prospectively assessed by Swissnoso according to CDC criteria. The effect of disease- and procedure-related factors on SSI was assessed in multivariable regression analysis, adjusting for patient-related factors. RESULTS: A total of 1072 IPOM implantations were performed. Laparoscopy was performed in 415 patients (38.7%), laparotomy in 657 patients (61.3%). SSI occurred in 172 patients (16.0%). Superficial, deep, and organ space SSI were found in 77 (7.2%), 26 (2.4%), and 69 (6.4%) patients, respectively. Multivariable analysis revealed emergency hospitalization (OR 1.787, p = 0.006), previous laparotomy (1.745, p = 0.029), duration of operation (OR 1.193, p < 0.001), laparotomy (OR 6.167, p < 0.001), bariatric (OR 4.641, p < 0.001), colorectal (OR 1.941, p = 0.001), and emergency (OR 2.510, p < 0.001) surgery, wound class ≥ 3 (OR 3.878, p < 0.001), and non-polypropylene mesh (OR 1.818, p = 0.003) as independent predictors for SSI. Hernia surgery was independently associated with a lower risk for SSI (OR 0.165, p < 0.001). CONCLUSION: This study revealed emergency hospitalization, previous laparotomy, duration of operation, laparotomy, as well as bariatric, colorectal, and emergency surgery, abdominal contamination or infection, and usage of non-polypropylene mesh as independent predictors for SSI. In contrast, hernia surgery was associated with a lower risk for SSI. The knowledge of these predictors will help to balance benefits of IPOM implantation against the risk for SSI.

PURPOSE: With robotic surgical devices, an innovative tool has stepped into the arena of minimally invasive hernia surgery. It combines the advantages of open (low recurrence rates and ability to perform complex procedure such as transverse abdominis release) and laparoscopic surgery (low rate of wound and mesh infections, less pain). However, a superiority to standard minimally invasive procedures has not yet been proven. We present our first experiences of robotic mesh repair of incisional hernias and a comparison of our results with open and minimally invasive sublay techniques. METHODS: A retrospective analysis of all patients who underwent robotic-assisted mesh repair (RAHR) for incisional hernia between April and November 2022 (RAHR group) and patients who underwent open sublay (Sublay group) or eMILOS hernia repair (eMILOS group) between January 2018 and November 2022 was carried out. Patients in the RAHR group were matched 1:2 to patients in the Sublay group by propensity score matching. Patient demographics, preoperative hernia characteristics and cause of hernia, intraoperative variables, and postoperative outcomes were evaluated. Furthermore, a subgroup analysis of only midline hernia was performed. RESULTS: A total of 21 patients received robotic-assisted incisional hernia repair. Procedures performed included robotic retro-muscular hernia repair (r-RMHR, 76%), with transverse abdominis release in 56% of the cases. In one patient, r-RHMR was combined with robotic inguinal hernia repair. Two patients (10%) were operated with total extraperitoneal technique (eTEP). Robotic-assisted transabdominal preperitoneal hernia repair (r-TAPP) was performed in three patients (14%). Median (range) operating time in the RAHR group was significantly longer than in the sublay and eMILOS group (291 (122-311) vs. 109.5 (48-270) min vs. 123 (100-192) min, respectively, p < 0.001). The meshes applied in the RAHR group were significantly compared to the sublay (mean (SD) 529 ± 311 cm2 vs. 356 ± 231, p = 0.037), but without a difference compared to the eMILOS group (mean (SD) 596 ± 266 cm2). Median (range) length of hospital stay in the RAHR group was significantly shorter compared to the Sublay group (3 (2-7) vs. 5 (1-9) days, p = 0.032), but not significantly different to the eMILOS group. In short term follow-up, no hernia recurrence was observed in the RAHR and eMILOS group, with 9% in the Sublay group. The subgroup analysis of midline hernia revealed very similar results. CONCLUSION: Our data show a promising outcome after robotic-assisted incisional hernia repair, but no superiority compared to the eMILOS technique. However, RAHR is a promising technique especially for complex hernia in patients with relevant risk factors, especially immunosuppression. Longer follow-up times are needed to accurately assess recurrence rates, and large prospective trials are needed to show superiority of robotic compared to standard open and minimally invasive hernia repair.

Background and Objectives: Inguinal hernia is a common surgical disease. Traditional open herniorrhaphy has been replaced by laparoscopic herniorrhaphy. Nowadays, many attempts at robotic herniorrhaphy have been reported in western countries, but there have been no reports in South Korea. The purpose of this study is to report our initial experience with robotic inguinal hernia surgery, compared to laparoscopic inguinal hernia surgery. Materials and Methods: We analyzed the clinical data from 100 patients who received inguinal hernia surgery in our hospital from November 2020 to June 2022. Fifty patients underwent laparoscopic surgery, and 50 patients underwent robotic surgery using the da Vinci Xi system. All hernia surgeries were performed by a single surgeon using the transabdominal preperitoneal (TAPP) method. Results: The mean operation time and hospital stay were not statistically different. On the first postoperative day, the visual analog scale (VAS) pain score was significantly lower in the robotic surgery group (2.9 ± 0.5 versus 2.5 ± 0.7, p = 0.015). Cumulative sum analysis revealed an approximately 12-case learning curve for robotic-assisted TAPP hernia surgery. Conclusions: Robotic-assisted TAPP inguinal hernia surgery is technically acceptable to surgeons who have performed laparoscopic inguinal hernia surgery, and the learning curve is relatively short. It is thought to be a good step toward learning other robot-assisted operations.

BACKGROUND: Inguinal hernia has a lifetime incidence of 27% in men and 3% in women. Surgery is the recommended treatment, but there is no consensus on the best method. Open repair is most popular, but there are concerns about the risk of chronic groin pain. Laparoscopic repair is increasingly accepted due to the lower risk of chronic pain, although its recurrence rate is still unclear. The aim of this overview is to compare the risk of recurrence and chronic groin pain in laparoscopic versus open repair for inguinal hernia. METHODS: We searched Ovid MEDLINE, EMBASE and the Cochrane Database of Systematic Reviews for systematic reviews and meta-analyses. Only reviews of randomised controlled trials (RCTs) in adults published in English were included. Conference proceedings and editorials were excluded. The quality of the systematic reviews was assessed using the AMSTAR 2 checklist. Two outcomes were considered: hernia recurrence and chronic pain. RESULTS: Twenty-one systematic reviews and meta-analyses were included. Laparoscopic repair was associated with a lower risk of chronic groin pain compared with open repair. In the four systematic reviews assessing any laparoscopic versus any open repairs, laparoscopic repair was associated with a statistically significant (range: 26-46%) reduction in the odds or risk of chronic pain. Most reviews showed no difference in recurrence rates between laparoscopic and open repairs, regardless of the types of repair considered or the types of hernia that were studied, but most reviews had wide confidence intervals and we cannot rule out clinically important effects favouring either type of repair. CONCLUSION: Meta-analyses suggest that laparoscopic repairs have a lower incidence of chronic groin pain than open repair, but there is no evidence of differences in recurrence rates between laparoscopic and open repairs.

PURPOSE: Robotic retromuscular abdominal wall repair (RAWR) for ventral hernias can be performed transabdominal or extraperitoneal by using an enhanced view totally extraperitoneal repair (eTEP). For defects in the meso- or epigastric region, an inverted approach can be used, starting the development of the totally extraperitoneal plane in the suprapubic region and progressing in a caudal-to-cranial direction (inverted TEP, iTEP). The aim of the study is to present the surgical technique and to report the short-term outcomes. METHODS: A retrospective analysis of a prospectively maintained database was performed, including patients who underwent a robotic RAWR using the iTEP approach between December 2019 and January 2022. The surgical technique was described, and patients' characteristics and intra- and postoperative parameters were studied and compared to the TARUP technique (robotic transabdominal retromuscular umbilical prosthetic hernia repair). RESULTS: Thirty-four patients were treated with an iTEP approach, and 14 patients underwent a TARUP procedure. The median length of stay was 1 day (range 1-3), and there were no intraoperative complications in both groups. One patient (3%) required reoperation after an iTEP approach for a small bowel internal herniation due to a rupture of the posterior rectus sheath. There were no recurrences or mortality with a median follow-up of 15 months (range 3-29) in the iTEP group, compared to 35 months (range 29-37) in the TARUP group. CONCLUSION: For defects in the upper abdominal region, a robotic RAWR with an iTEP approach appears to be safe and feasible. Long-term follow-up is needed to evaluate the late recurrence rate.

PURPOSE: Recently, robotic surgery has been increasingly performed in hernia surgery. Although feasibility and safety of robot-assisted inguinal hernia repair in an inpatient setting have been already shown, its role in outpatient hernia surgery has not yet been investigated. Thus, this study aimed to compare robot-assisted TAPP (r-TAPP) and conventional laparoscopic TAPP (l-TAPP) in an outpatient setting. METHODS: A prospective database of patients with inguinal hernia treated by l-TAPP or r-TAPP in an outpatient setting during a 1-year period was analyzed in a comparative cohort study. All patients underwent a check-up appointment with their surgeon within 3 days and 6 weeks postoperatively. Data on surgical time, perioperative complications, and postoperative pain were collected. Pain was recorded by using a Verbal Rating Scale (VRS). RESULTS: Overall, outpatient laparoendoscopic inguinal hernia repair was performed in 58 patients (29 l-TAPP; 29 r-TAPP). Mean age was 57 years (21-81), mean BMI 24.5 kg/m2 (19-33) with no differences between both groups. Most patients reported none or only a low postoperative pain level in both groups (89.6% in l-TAPP group; 100% in r-TAPP), while there was a trend for less pain after r-TAPP. In both groups, there was one case of postoperative hematoma, which was successfully treated by conservative means. No other complications occurred during follow-up in either group and there was no 30-day-readmission, no unplanned overstay or any 30-day mortality in the cohort. CONCLUSION: Robot-assisted inguinal hernia surgery can be safely performed in an outpatient setting with a tendency to less pain when compared to the conventional laparoscopic technique. Cost-effectiveness and cost-coverage of outpatient robot-assisted inguinal hernia surgery must be further investigated in times of limited health cost resources and diagnosis-related medical reimbursements.

Background: Ultrasound-guided truncal nerve blocks are increasingly used for postoperative pain relief after abdominal surgery. Aim: The aim of this prospective and randomized study was to compare posterior transversus abdominis plane block (pTAPB) with posterior quadratus lumborum block (pQLB) for postoperative analgesic efficacy in patients undergoing unilateral inguinal hernia surgery under general anesthesia (GA). Patients and Methods: A total of 90 adult patients were randomized into 3 groups: group pTAPB (n = 30), group pQLB (n = 30), and group Control (n = 30). The patients in groups pQLB and pTAPB received a unilateral block using 20 ml of 0.25% bupivacaine after the induction of GA. Intravenous (IV) tramadol patient control group analgesia (PCA) and paracetamol were used in the postoperative period as a part of the multimodal analgesic regimen in both groups. Postoperative pain was assessed using a visual analog scale (VAS) during postoperative 24 h. Dexketoprofene was used as a rescue analgesic when VAS is >3. The primary outcome measure was mean pain scores. Secondary outcome measures were consumption of rescue analgesics and the amount of tramadol delivered by PCA. P <0.05 was considered statistically significant. Results: Mean VAS scores were significantly lower in the group pQLB than group pTAPB and group Control at all-time points (pQLB < pTAPB < Control; P < 0.001). Rescue analgesic was not required in group QLB. Rescue analgesic consumption, the number of bolus demand on PCA, and total PCA dose were highest in group Control and lowest in the pQLB group (Control > pTAPB > pQLB; P < 0.001). Conclusion: It is concluded that both pQLB and pTAPB provided effective pain relief after unilateral inguinal hernia surgery. pQLB was superior to pTAPB due to lower pain scores and analgesic consumption.

BACKGROUND: Contrary to adult inguinal hernia surgery, large-scale investigations using registries or administrative data are missing in paediatric surgery. We aimed to fill this gap by analysing German administrative hospital data to describe the current reality of inpatient hernia surgery in children. METHODS: We analysed aggregated data files bought from the German federals statistics office on hospital reimbursement data separately for principal diagnoses of inguinal hernia in children and for herniotomies in inpatients. Developments over time were assessed via regression and differences between groups with nonparametric comparisons. RESULTS: Principal diagnoses of hernias were decreasing over time with the exception of male bilateral and female bilateral incarcerated hernias in the first year of life which increased. The vast majority of operations were conducted via the open approach and laparoscopy was increasingly only used for females older than 1 year of age. Recurrent hernia repair was scarce. Rates of inguinal hernia repair were higher in both sexes the younger the patient was, but were also decreasing in all age groups despite a population growth since 2012. The amount of inguinal hernia repairs by paediatric surgeons compared to adult surgeons increased by 1.5% per year. CONCLUSIONS: Our results corroborate previous findings of age and sex distribution. It demonstrates that inpatient hernia repair is primarily open surgery with herniorrhaphy and that recurrences seem to be rare. We observed decreasing rates of hernia repairs over time and as this has been described before in England, future studies should try to elucidate this development. LEVEL OF EVIDENCE: III.

BACKGROUND AND AIMS: Caudal epidural and ultrasound-guided ilioinguinal, iliohypogastric nerve (IL/IH) blocks are commonly used regional anesthesia techniques for postoperative analgesia in pediatric inguinal surgeries. Dexmedetomidine as an adjuvant has been proven to prolong the duration of both neuraxial and peripheral nerve blocks. We compared the duration of analgesia provided by local anesthetic (LA) and dexmedetomidine for caudal and IL/IH block for pediatric inguinal surgeries. MATERIAL AND METHODS: Forty-six children undergoing inguinal hernia repair were selected for this randomized double-blind study. After general anesthesia, children received either 0.75 mL.kg-1 of 0.25% bupivacaine with 1 mcg.kg-1 of dexmedetomidine in caudal epidural or 0.25 mL.kg-1 of 0.25% bupivacaine with 1 mcg.kg-1 of dexmedetomidine in IL/IH block. The pain was assessed up to 24 h postoperatively using face, legs, activity, cry, consolability (FLACC) score. For FLACC ≥4, rescue analgesia was provided using 1 µg/kg of intravenous fentanyl, up to 2 h postoperatively and 10 mg/kg of oral ibuprofen between 2 and 24 postoperative hours. The time for first rescue analgesia was taken as the duration of analgesia. RESULTS: There were no significant differences in the pain scores or analgesic utilization between the groups. The duration of analgesia of caudal and IL/IH blocks was similar (720.3 ± 430.1 min and 808.4 ± 453.1 min, respectively). The time taken for the performance of block was significantly higher for caudal compared to IL/IH (547 ± 93 vs. 317 ± 179 s; P < 0.001). CONCLUSION: Both caudal epidural and USG-IL/IH block with dexmedetomidine as additive provide the comparable duration of postoperative analgesia with no significant side effects.
RESUMEN
BACKGROUND: The suitability of ambulatory surgery in obese patients remains controversial. This study aimed to investigate the "cutoff" value of body mass index (BMI) associated with increased likelihood of hospital readmissions within the first 24 hours of surgery in patients undergoing ambulatory hernia repair. MATERIALS AND METHODS: The study used data from the 2012-2016 American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP). Cochran Armitage trend tests were conducted to assess progression in rates hospital readmissions across categories of patient BMI. The minimum p-value method, Kolmogorov-Smirnov goodness of fit tests, logistic regression, and receiver-operating characteristic (ROC) curve analyses were used to investigate the cutoff of patient BMI indicative of increased likelihood of readmissions. RESULTS: A total of 214,125 ambulatory hernia repair cases were identified. Of those, 908 patients (0.42%) had an unexpected hospital admission within the first 24 hours after surgery. The readmission rates did not significantly increase across the categories of BMI. However, some of the reasons for readmission significantly differed by BMI category. Logistic regression analysis revealed no statistically significant association between BMI and hospital readmissions (odds ratio [95% Cl], 0.96 [0.91-1.02] P = .179). An optimal BMI threshold predictive of an increased likelihood of hospital readmissions was not identifiable by any of the statistical methods used. CONCLUSIONS: Although reasons for readmission differed by BMI category, there is no clear cutoff value of BMI associated with increased hospital readmission within the first 24 hours after surgery.

BACKGROUND: Neonates and infants undergoing general anaesthesia for hernia surgery are at risk of perioperative cardiorespiratory adverse events. The use of regional anaesthesia with dexmedetomidine preserves airway tone and may potentially avoid these complications. This study compares the perioperative conditions and adverse events between dexmedetomidine sedation with caudal block and general anaesthesia with caudal block for inguinal hernia surgery in infants. METHODS: A randomised controlled trial was conducted in a tertiary hospital in Singapore involving 104 infants younger than 3 months, who were randomised to receive either dexmedetomidine sedation (DEX) with caudal block or general sevoflurane anaesthesia with tracheal intubation and caudal block (GA) for inguinal hernia surgery. Perioperative conditions, haemodynamics and adverse events were compared between groups. RESULTS: Fifty-one infants received DEX and 48 infants received GA. In the DEX group, 46 infants (90.2%) had their operations completed solely under this technique, two (3.9%) were converted to general anaesthesia with intubation, and three (5.9%) required brief administration of nitrous oxide or low-dose sevoflurane. Overall, 96.1% of infants in the DEX group did not require intubation. Perioperative conditions were similar in both groups. The DEX group had significantly lower heart rates and higher mean arterial pressures intraoperatively. Two infants in the DEX group (3.9%) required postoperative intensive care admission compared with six infants (12.5%) in the GA group. CONCLUSIONS: Dexmedetomidine sedation with caudal block provides a feasible alternative to general anaesthesia in infants undergoing hernia surgery. This technique avoids the need for tracheal intubation, which may be beneficial in neonates. CLINICAL TRIAL REGISTRATION: NCT02559102.

BACKGROUND: Debate persists on the optimal management of incisional hernias due to paucity of accurate recurrence rates. Reoperation rates implicate a severe underestimation of the risk of a recurrence. Therefore, long-term postoperative clinic visits allowing physical examination of the abdomen are deemed necessary. However, these are time and costs consuming. Aim of this study was to develop and evaluate a new screenings method for recurrent hernias, the 'PINCH-Phone' (Post-INCisional-Hernia repair-Phone). METHODS: The PINCH-Phone is a telephone questionnaire. In this multicenter prospective study, the PINCH-Phone was answered by patients after incisional hernia repair. Afterwards the patients were seen at the clinic and physical examination was done to detect any recurrences. RESULTS: The PINCH-Phone questions were answered by 210 patients with a median postoperative follow-up of 36 months. Fifty-six patients were seen after multiple incisional hernia repairs. In 137 patients who had replied positively to one or more questions, 28 recurrent incisional hernias were detected at physical examination. Six recurrences were noted in 73 patients who had replied negatively to all questions. The overall sensitivity and specificity of the PINCH-Phone were 82% and 38%, respectively. CONCLUSION: The PINCH-Phone appears a simple and valuable screenings method for recurrences after incisional hernia repair and, hence, is recommended for implementation.

BACKGROUND: The International Hernia Collaboration (IHC) is a closed Facebook™ group that allows international surgeons to post clinical questions and exchange transparent feedback with the intent to optimize patient outcomes. Despite the educational value of closed FB groups, CME credits have not been available to members. To determine feasibility of and user interest in earning CME credit through social media, the IHC piloted a series of expert lectures followed by an interactive Facebook Live session as a novel pathway offering CME credit. METHODS: Nine monthly lectures and Facebook Live sessions were presented. CME credit was offered for the final seven lectures. Participation in the form of views, comments, and likes was quantified by a Facebook analytics service and an engagement score, defined as [(the number of comments × 2) + (the number of reactions)], was calculated for each lecture and Facebook Live session. CME credit was obtained through a two-question quiz. RESULTS: Of 5400 + Facebook members of the IHC, an average of 1116 (20.4 ± 4.0%) viewed the live session event following each lecture (n = 9 events). The average Facebook engagement score for Facebook Live was 259 ± 75, a significant difference with the average Facebook engagement score on the IHC (40.8) over the same time period (p < 0.001). On average, 16 users [range 8-35, (n = 7 events)] claimed CME credit for each educational series. CONCLUSIONS: Closed Facebook groups can be a useful media to offer educational content and CME credit. The pilot IHC Lecture and Facebook Live series offering CME credit resulted in significantly more engagement amongst its members compared to other posts during the same time period. A small portion of participants qualified for CME credit. Future social media educational series may increase participants qualifying for CME by streamlining the interface to obtain CME credit.

Pierre Franco (1505-1578) was a brilliant surgeon of the Renaissance, a contemporary of Ambroise Paré. He made an impact on the history of surgery with his innovative approaches in the treatment of hernia, lithotomy, and the use of the suprapubic incision. The purpose of this study is to present a detailed account of his work, innovations, and achievements as well as the impact he made on the surgery of the Renaissance.

BACKGROUND: To assess the construct validity and responsiveness of the PROMIS Physical Function v1.2 short form 8b (PROMIS-PF), and the PROMIS Ability to Participate in Social Roles and Activities v2.0 short form 8a (PROMIS-APS) in postoperative recovery. METHODS: An observational pilot study was conducted in which 30 patients participated, undergoing various forms of abdominal surgery. Patients completed the PROMIS-PF and PROMIS-APS, the Short Form 36 Health Survey (SF-36) and the World Health Organization Disability Assessment Schedule 2.0 (WHODAS) at several time points before and after surgery. The construct validity and responsiveness of the two PROMIS short forms were evaluated by testing pre-defined hypotheses and were considered adequate when at least 75% of the data was consistent with the hypotheses. Construct validity was evaluated by calculating Spearman correlations and the responsiveness by calculating effect sizes. RESULTS: 6/7 (85.7%) of the results were consistent with the hypotheses supporting the construct validity of the PROMIS-PF. For the PROMIS-APS this was the case in 7/15 (46.7%) of the results. For the PROMIS-PF, 6/7 (85.7%) of the results were consistent with the hypotheses, supporting responsiveness. Regarding the responsiveness of the PROMIS-APS, only 7 out of 13 (53.8%) of these results were consistent with the hypotheses. CONCLUSIONS: This study supported the construct validity and the responsiveness of the PROMIS-PF v1.2 short form 8b for measuring recovery in abdominal surgery. Considering the major advantages of PROMIS, we recommend the use of the PROMIS-PF in abdominal surgery.
