RESUMO
BACKGROUND: Trans-abdominal pre-peritoneal (TAPP) hernia repair is a complex procedure that presents several challenges. Even though, due to the high prevalence of inguinal hernia, TAPP technique is increasing in frequency and robotic Abdominal Wall Surgery (rAWS) is emerging as a valuable tool in this regard. Although inguinal TAPP procedure principles have been published and simulation is needed, the availability of validated models remains scarce. METHODS: A new low-cost model was developed to simulate inguinal rTAPP repair. For validity assessment, a new TAPP-specific fidelity questionnaire and assessment scale were developed to compare the performance of novices and experts in the simulated procedure. The models used were assessed at 60 min for execution and quality score. RESULTS: Twenty-five residents and specialists from all over the country participated in this study. Execution, quality, and global performance was higher in the seniors group compared to juniors (8.91 vs 6.36, p = 0.02; 8.09 vs 5.14, p < .001; and 17 vs. 11,5, p < .001, respectively). Overall fidelity was assessed as being very high [4.41 (3.5-5.0), α = .918] as well as face [4.31 (3.0-5.0), α = .867] and content validity [4.44 (3.2-5.0), α = .803]. Participants strongly agreed that the model is adequate to be used with the DaVinci® Robot [4.52 (3.5-5.0), α = .758]. CONCLUSION: This study shows face, content, and construct validity of the model for inguinal TAPP simulation, including for robotic surgery. Therefore, the model can be a valuable tool for learning, understanding, practicing, and mastering the TAPP technique prior to participating in the operating room.

BACKGROUND: Hernioplasty is one of the most commonly performed surgeries. However, the optimal procedure for young adults has not been defined yet. Our study compared the outcomes of laparoscopic percutaneous extraperitoneal closure (LPEC) in young adults with outcomes in children. MATERIAL AND METHODS: We retrospectively reviewed patients aged 0-30 years who underwent LPEC. Data regarding age, sex, hernia type, surgical time, pre-intraoperative laterality, contralateral patent processus vaginalis (CPPV), and complications were analyzed. RESULTS: LPEC was performed on 2642 patients in our hospital. Of these, 51 patients were young adults (aged 15-30 years). Asymptomatic CPPV in unilateral patients was frequent in the <15-year age group (50.2%) compared to the 15-30-year age group (15.9%). The median surgical time was shorter in the <15-year age group (19 min, interquartile range [IQR]: 24-33) compared to that of the 15-30-year age group (33 min, IQR: 23.3-40.8). CONCLUSIONS: This is the first report on the outcomes in young adult patients who underwent LPEC. The median surgical time was longer in the 15-30-year age group than in the <15-year age group. The median follow-up was 4.7 years with no intra-postoperative complications, such as postoperative bleeding, infection, persistent pain, and recurrence. LPEC is an effective, cosmetic, and safe surgical treatment in young adults and children.

Outdoor PM2.5 was sampled in Pretoria, 18 April 2017 to 28 February 2020. A case-crossover epidemiology study was associated for increased PM2.5 and trace elements with increased hospital admissions for respiratory disorders (J00-J99). The results included a significant increase in hospital admissions, with total PM2.5 of 2.7% (95% CI: 0.6, 4.9) per 10 µg·m-3 increase. For the trace elements, Ca of 4.0% (95% CI: 1.4%-6.8%), Cl of 0.7% (95% CI: 0.0%-1.4%), Fe of 3.3% (95% CI: 0.5%-6.1%), K of 1.8% (95% CI: 0.2-3.5) and Si of 1.3% (95% CI: 0.1%-2.5%). When controlling for PM2.5, only Ca of 3.2% (95% CI: 0.3, 6.1) and within the 0-14 age group by 5.2% (95% CI: 1.5, 9.1). Controlling for a co-pollutant that is highly correlated with PM2.5 does reduce overestimation, but further studies should include deposition rates and parallel sampling analysis.

Background & Objective: Laparoscopic surgery is generally considered as better than open surgery in terms of less complications, minimal hospital stays and quick healing of the wounds. Our objective was to compare the immediate and early outcome of the different incarcerated hernias of anterior abdominal wall operated on as emergency cases by open and laparoscopic approach. Methods: This is a retrospective comparative study which was conducted at two hospitals of AlAhsa city of the Eastern region of the Kingdom of Saudi Arabia from July, 2017 to June, 2022. The data were retrieved from the medical records of the hospitals. All male and female patients having different types of incarcerated hernias of anterior abdominal wall presenting to the emergency room were included in the study. The patients were divided in two groups; those who were operated on by open approach (Group-I) and those who were operated on by laparoscopic approach (Group-II). Results: Out of total 70 male and female patients, 42 were in Group-I and 28 in Group-II. The variety of the incarcerated hernias in both groups overall was para-umbilical 26(37.14%), incisional 18(25.71%), inguinal (right & left) 17(24.28%) and epigastric 9(12.86%). The mean operative time taken by Group I and II was 126.07 (±9.728) and 98.57 (±10.079) minutes respectively with a difference of 27.50 minutes (p=0.807). The mean hospital stay of the patients in Group I and II was 1.36(±0.719) and 1.57(±0.997) days respectively (p=0.482). The post-operative complications rate in Group-I was 6(14.28%) and in Group-II, 6(21.43%) (p=0.658). Overall, 12(17.14%) patients developed the complications in both groups. When the number of the complications is compared, it shows that there was no significant difference between the two groups (p=0.583). Conclusion: Laparoscopic approach is not superior to the open approach in the terms of the immediate and early outcome/complications of the incarcerated hernias of the anterior abdominal wall operated as emergency cases in this study.
RESUMO
OBJECTIVE: To review the first robotic hernia repairs performed at the Ilyinsky Hospital, evolution of this technology, learning curve and early outcomes. MATERIAL AND METHODS: There were 17 procedures at the Ilyinskaya Hospital between 2021 and 2023 (13 men and 4 women). Mean age was 60 years, body mass index 28 kg/m2. ASA grade 1 was observed in 1 patient, grade 2 - 14 ones, grade 3 - 2 patients. Ventral, inguinal and umbilical hernias were diagnosed in 7, 8 and 2 cases, respectively. Ventral hernias required IPOM+ procedure in 3 cases, eTEP-RS procedure in 2 cases and eTEP-RS-TAR procedure in 2 cases. Patients with inguinal hernia underwent transabdominal preperitoneal hernia repair. In case of umbilical hernia, TARUP procedure was performed in 1 case and vTAPP procedure in 1 case. RESULTS: Mean surgery time was 2 hours 38 min (min 1 hour 35 min, max 10 hours 11 min). There was one intraoperative complication (bleeding from epigastric artery). The follow-up period ranged from 3 months to 3 years. There were no recurrent hernias. Postoperative complications were noted in 2 cases. One patient was diagnosed with epididymitis after TAPP, 1 patient - with seroma after eTEP-RS procedure. All complications were relieved by conservative treatment. Bleeding from a. epigastrica inferior was diagnosed after removal of the trocar at the end of surgery. This event required suturing. CONCLUSION: Robotic hernia repair appears to be technically feasible and safe. This approach provides favorable results regarding quality of life and recurrence rate.

MAIN CONCLUSION: TabZIP60 is found to interact with TaCDPK30 and act as a positive regulator of ABA synthesis-mediated salt tolerance in wheat. Wheat basic leucine zipper (bZIP) transcription factor (TabZIP60) was previously found to act as a positive regulator of salt resistance. However, its molecular mechanism in response to salt stress in wheat is still unclear. In this study, TabZIP60 was found to interact with wheat calcium-dependent protein kinase (TaCDPK30), which belonged to group III of CDPK family, and was induced by salt, polyethylene glycol, and abscisic acid (ABA) treatments. This mutation of serine 110 in TabZIP60 resulted in no interaction with TaCDPK30. Moreover, TaCDPK30 was involved in interactions with wheat protein phosphatase 2C clade A (TaPP2CA116/TaPP2CA121). TabZIP60-overexpressing wheat plants showed increased salt tolerance, as exhibited by better growth status, higher soluble sugar, and lower malonaldehyde contents of transgenic plants than wild-type wheat cv. Kenong 199 under salt stress. Moreover, transgenic lines showed high ABA content by upregulating ABA synthesis-related gene expression levels. TabZIP60 protein could bind and interact with the promoter of the wheat nine-cis epoxycarotenoid dioxygenase (TaNCED2) gene. Furthermore, TabZIP60 upregulated several stress response gene expression levels, which could also increase the plant's ability to resist salt stress. Thus, these results suggest that TabZIP60 could function as a regulator of ABA synthesis-mediated salt tolerance through interacting with TaCDPK30 in wheat.

OBJECTIVE: To investigate the differences in hernia recurrence and chronic postoperative inguinal pain (CPIP) in randomized, controlled trials comparing fixation and non-fixation of the mesh in laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair. METHODS: A multi-database systematic search was conducted for randomized, controlled trials comparing fixation versus non-fixation of the mesh in TAPP inguinal hernia repair. All eligible papers were assessed for risk of bias using the revised Cochrane risk of bias tool for randomized trials (RoB 2.0). Quality of evidence was evaluated using the GRADE system. Meta-analyses were performed regarding recurrence and CPIP using RevMan. RESULTS: Seven prospective, randomized controlled trials were included. Laparoscopic TAPP inguinal hernia repair was performed in 1732 patients with 737 procedures performed without fixation and 995 procedures with fixation of the mesh. Despite all trials being RCTs, the trials were limited by substantial bias and the quality of evidence was low regarding hernia recurrence and very low regarding CPIP. Pooled estimates from meta-analyses were an OR of 2.80 (95% CI 0.61-12.77) for hernia recurrence and a mean difference in visual analogue scale (VAS) of 0.17 (95% CI 0.90-1.24) for CPIP, respectively. CONCLUSION: The current evidence is very uncertain and mesh fixation may have little to no effect regarding hernia recurrence and chronic postoperative inguinal pain in patients operated with TAPP inguinal hernia repair.

BACKGROUND: Although international guidelines recommend not fixing the mesh in almost all cases of laparoendoscopic repairs, in case of large direct hernias (M3) mesh fixation is recommended to reduce recurrence risk. Despite lack of high-quality evidence, the recommendation was upgraded to strong by expert panel. The authors conducted a research experiment to verify the hypothesis that it is possible to preserve the mesh in the operating field in large direct hernias (M3) without the need to use fixing materials. METHOD: The authors conducted an experiment with scientists from Universities of Technology in a model that reflects the conditions in the groin area. By simulating conditions of the highest possible intra-abdominal pressure, they examined the mesh behavior within the groin and its ability to dislocate under the forces generated by this pressure. The experiment involved six spatial implants and one flat macroporous mesh. RESULTS: Heavyweight spatial meshes and lightweight spatial-individualized meshes showed no tendency to dislocate or move directly to the orifice, which was considered a rapid hernia recurrence. Lightweight meshes, both spatial and flat, underwent significant migration and shifting toward the hernial orifices. CONCLUSION: Based on the results, we believe that mesh fixation is not the only alternative to preventing recurrence in complex defects. Similar effects can be achieved using a larger, more rigid, and anatomically fitted implant. The type of implant (rather than its fixation) seems to be a key factor from the point of view of mechanics and biophysics. Clinical trials confirming the results in vivo will allow to supplement or amend the guidelines for the treatment of large inguinal hernias.

BACKGROUND: Femoral hernia (FH) is traditionally treated by open surgery (OS). Laparoscopic treatment has also shown good results in treating FH. However, there have been few comparative studies of these two techniques. Therefore, our aim was to compare the outcomes of open and laparoscopic surgical FH treatment. METHODS: Adult patients with primary unilateral FH undergoing OS or transabdominal preperitoneal (TAPP) hernia repair at our hospital from January 2013 to June 2018 were included in this study. Patients with history of abdominal surgery, contraindications to general anesthesia and those not wishing to receive general anesthesia received OS. Demographics, operation details and complications were compared retrospectively between the two groups. RESULTS: A total of 132 patients were recruited to the study, 62 and 70 of whom underwent OS and TAPP, respectively. Compared to OS group, the TAPP group had a significantly shorter hospital stay (3.0 vs. 2.0 days, respectively, P < 0.05) and a lower postoperative pain score (3.0 vs. 1.0, P < 0.05), and took less time to return to normal activities (13.0 vs. 6.0 days, respectively, P < 0.05). The overall complication rates were equivalent between the groups (10 vs. 9.7%, OR = 1.037, 95% CI 0.329-3.270). CONCLUSIONS: Both laparoscopic and open surgery appear to be safe and effective in a cohort of patients with femoral hernia and laparoscopic surgery might offer some advantages in reducing length of hospital stay, lower postoperative pain score and quicker return to activities.

BACKGROUND: Since the introduction of minimally invasive surgery, new techniques like transabdominal preperitoneal (TAPP) repair have progressively gained acceptance for the treatment of groin hernia. Laparoscopic TAPP (LTAPP) is recommended for bilateral repairs. Likewise, the introduction of robotic platforms has promised additional surgical benefits for robotic TAPP (RTAPP), which are yet to be confirmed. This study compared multicenter data obtained from patients undergoing bilateral inguinal hernia repair with RTAPP, performed during the preliminary learning curve period, versus conventional LTAPP. MATERIALS AND METHODS: All consecutive bilateral inguinal hernia patients from four Italian centers between June 2015 and July 2020 were selected. A propensity score model was used to compare patients treated with LTAPP versus RTAPP, considering sex, age, body mass index, current smoking status, overall comorbidity, hernia classification (primary or recurrent), and associated procedures as covariates. After matching, intraoperative details and postoperative outcomes were evaluated. RESULTS: In total, 275 LTAPP and 40 RTAPP were performed. After matching, 80 and 40 patients were allocated to the LTAPP and RTAPP cohorts, respectively. No intraoperative complications or conversion to open surgery occurred. However, a longer operative time was recorded in the RTAPP group (79 ± 21 versus 98 ± 29 min; p < 0.001). Postoperative visual analog scale (VAS) pain scores (p = 0.13) did not differ and complication rates were similar. There were no clinical recurrences in either group, with mean follow-up periods of 52 ± 14 (LTAPP) and 35 ± 8 (RTAPP) months. A statistical difference in length of hospital stay was found between the groups (1.05 ± 0.22 vs 1.50 ± 0.74 days; p < 0.001). CONCLUSION: In this patient population, outcomes for bilateral inguinal hernia repair appear comparable for RTAPP and LTAPP, except for a shorter recovery after laparoscopic surgery. A longer operative time for robotic surgery could be attributable to the learning curve period of each center.

BACKGROUND: The aim of this study was to assess the transferability of surgical skills for the laparoscopic hernia module between the serious game Touch Surgery™ (TS) and the virtual reality (VR) trainer Lap Mentor™. Furthermore, this study aimed to collect validity evidence and to discuss "sources of validity evidence" for the findings using the laparoscopic inguinal hernia module on TS. METHODS: In a randomized crossover study, medical students (n = 40) in their clinical years performed laparoscopic inguinal hernia modules on TS and the VR trainer. TS group started with "Laparoscopic Inguinal Hernia Module" on TS (phase 1: Preparation, phase 2: Port Placement and Hernia Repair), performed the module first in training, then in test mode until proficiency was reached. VR group started with "Inguinal Hernia Module" on the VR trainer (task 1: Anatomy Identification, task 2: Incision and Dissection) and also performed the module until proficiency. Once proficiency reached in the first modality, the groups performed the other training modality until reaching proficiency. Primary endpoint was the number of attempts needed to achieve proficiency for each group for each task/phase. RESULTS: Students starting with TS needed significantly less attempts to reach proficiency for task 1 on the VR trainer than students who started with the VR trainer (TS = 2.7 ± 0.6 vs. VR = 3.2 ± 0.7; p = 0.028). No significant differences for task 2 were observed between groups (TS = 2.3 ± 1.1 vs. VR = 2.1 ± 0.8; p = 0.524). For both phases on TS, no significant skill transfer from the VR trainer to TS was observed. Aspects of validity evidence for the module on TS were collected. CONCLUSION: The results show that TS brought additional benefit to improve performances on the VR trainer for task 1 but not for task 2. Skill transfer from the VR trainer to TS could not be shown. VR and TS should thus be used in combination with TS first in multimodal training to ensure optimal training conditions.

BACKGROUND: The effects of hernia repair on testicular function remain uncertain, regardless of the technique used. Studies that analyze testicular volume and flow after hernia repair or hormonal measurements are scarce and show contradictory results. This study aimed to evaluate the impact of bilateral inguinal hernia repair on male fertility in surgical patients in whom the Lichtenstein and laparoscopic transabdominal preperitoneal (TAPP) techniques were used. METHODS: A randomized clinical trial comparing open (Lichtenstein) versus laparoscopic (TAPP) hernia repair using polypropylene mesh was performed in 48 adult patients (20 to 60 years old) with primary bilateral inguinal hernia. Patients were evaluated preoperatively and 90 and 180 postoperative (PO) days. Sex hormones (Testosterone, FSH, LH and SHGB) analysis, testicular ultrasonography, semen quality sexual activity changes and quality of life (QoL) were performed. Postoperative pain was evaluated using the visual analog scale (VAS). RESULTS: Thirty-seven patients with aged of 44 ± 11 years were included, 19 operated on Lichtenstein and 18 operated on TAPP. The surgical time was similar between techniques. The pain was greater in the Lichtenstein group on the 7th PO day. The biochemical and hormonal analyses, testicular ultrasonography (Doppler, testicular volume, and morphological findings) and sperm quality were similar between groups. However, the sperm morphology was better in the Lichtenstein group after 180 days (p < 0.05 vs. preoperative) and two patients who underwent Lichtenstein hernia repair had oligospermia after 180 days. The QoL evaluation showed a significant improvement after surgery in the following domains: physical function, role emotional, bodily pain and general health (p < 0.05). On comparison of Lichtenstein vs. TAPP none of the domains showed statistically significant differences. No patient reported sexual changes. CONCLUSION: Bilateral inguinal hernia repair with polypropylene mesh, whether using Lichtenstein or TAPP, does not impair male fertility in terms of long-term outcomes.

BACKGROUND: The utilization of the robot for inguinal hernia repairs has increased in the past years. The new Da Vinci Single Port (SP) system provides the benefits of single-incision procedures and might overcome the technical difficulties of previous single-incision techniques. The aim of this study was to evaluate the safety and feasibility of the SP transabdominal preperitoneal inguinal hernia repair (SP-TAPP) and compare its outcomes to the robotic multiport technique (MP-TAPP). METHODS: A prospective cohort of patients who underwent a robotic SP-TAPP and MP-TAPP between 2012 and 2022 was analyzed. Primary endpoints were same-day discharge, morbidity, and inguinal recurrence rates. Secondary endpoints included conversion, operative time, port-site incisional hernia, and chronic pain. RESULTS: MP-TAPP and SP-TAPP were performed in 378 (81.3%) and 87 (18.7%) patients, respectively. Demographics were similar between groups. There were no conversions or intraoperative complications. Mean operative (MP-TAPP: 93.2 vs. SP-TAPP: 78.1 min, p = 0.003) and recovery time (MP-TAPP: 160.8 vs SP-TAPP: 112.6 min, p < 0.001) were significantly shorter in the SP group. Same-day discharge rate was higher (MP-TAPP: 86.5% vs. SP-TAPP: 97.7%, p = 0.001) after SP-TAPP; 30-day morbidity, readmissions, and chronic pain rates were similar between groups. After a mean follow-up of 30.6 months for MP-TAPP and 13.3 months for SP-TAPP, inguinal hernia recurrence and port-site incisional rates were similar between groups. CONCLUSION: Robotic SP-TAPP is safe and feasible. When compared to MP-TAPP, it showed similar postoperative morbidity, higher same-day discharge rates, and a quicker postoperative recovery. Further studies are needed to confirm the benefits of the SP platform.

PURPOSE: Robotic surgery offers new possibilities in repairing complex hernias with a minimally invasive approach. This study aimed to analyze our preliminary results. METHODS: Between November 2015 and February 2020, 150 patients underwent robotic reconstruction for abdominal wall defects (77 primary and 73 incisional). A retrospective analysis of a prospectively maintained database was conducted to evaluate the short-term outcomes. RESULTS: The mean operative time was 176.9 ± 72.1 min. No conversion to open or laparoscopic approach occurred. The mean hospital length of stay was 2.6 ± 1.6. According to Clavien-Dindo classification, two (grade III) complications following retromuscular mesh placement (1.3%) occurred. One patient (0.7%) required surgical revision due to small bowel occlusion following an intraparietal hernia. The 30-day readmission rate was 0.6%, and the mortality was nihil. CONCLUSIONS: Robotic surgery is valuable for safely completing challenging surgical procedures like complex abdominal wall reconstruction, with low conversion and complication rates. A stepwise approach to the different surgical techniques is essential to optimize the outcomes and maximize the benefits of the robotic approach.

PURPOSE: Less than 450 cases of femoral hernias containing the vermiform appendix have been published since De Garengeot's first description. A laparoscopic treatment option opened 15 years ago seems reliable and safe. A literature review of all the patients who have benefited from this new therapeutic alternative is presented. METHODS: A systematic review using the German Society of Surgery's recommendations was performed for De Garengeot's hernias totally treated laparoscopically. Keywords searched included "De Garengeot hernia" OR "femoral hernia appendix" OR "crural hernia appendix." RESULTS: Only 29 out of 225 De Garengeot hernia's manuscripts were identified describing patients entirely treated laparoscopically: 25 patients by a transabdominal preperitoneal hernia repair (TAPP) and 4 patients by a total extraperitoneal (TEP) procedure; 85.1% were females. The mean age was 71 years. Twenty-two patients had pre-operative imaging tests, sonography (2), computed tomography (14), or both (6). Nevertheless, only 56% had a preoperative diagnosis. Twenty-one cases required urgent treatment, while programmed surgery was possible in 7 instances. An appendix-sparing procedure could be done in 16% of the TAPPs. No postoperative complications occurred. The median hospital stay was 2.5 days. CONCLUSIONS: The best surgical approach for a De Garengeot's hernia is not defined, and many critical questions remain unanswered. A better understanding of the diagnosis and treatment of this peculiar hernia will supply guidelines for clinicians who may encounter it hereafter. A fully laparoscopic approach seems perfectly safe and feasible for this entity, and it could be considered the first-line alternative if enough expertise is available.

BACKGROUND: Inguinal hernia repair is a common procedure in surgery. Patients with cardiovascular disease have an increased operative risk for postoperative morbidity. The study aimed to identify the most beneficial surgical procedure for these patients. METHODS: Patients undergoing elective surgery for unilateral or bilateral inguinal hernia between December 2015 and February 2020 were included. The cohort was divided into the group of patients with (CVD group) and without (NO group) cardiovascular disease and analyzed according to the postoperative morbidity distribution and correlated to the surgical technique used. RESULTS: Of the 474 patients included 223 (47%) were operated on using the Lichtenstein technique and 251 (53%) using TAPP, respectively. In the CVD group the Lichtenstein procedure was more common (n = 102, 68.9%), in the NO group it was TAPP (n = 205, 62.9%; p < 0.001). 13 (8.8%) patients in the CVD group and 12 (3.7%) patients in the NO group developed a postoperative hematoma (p = 0.023). In the further subgroup analysis within the CVD group revealed cumarine treatment as a risk factor for postoperative hematoma development, whereas the laparoscopic approach did not elevate the morbidity risk. CONCLUSION: CVD is a known risk factor for perioperative morbidity in general surgery, however, the TAPP method does not elevate the individual perioperative risk.

PURPOSE: Groin hernias are a common condition that can be treated with various surgical techniques, including open surgery and laparoscopic approaches. Laparoscopic surgery has several advantages but its use is limited due to the complexity of the posterior inguinal region and the need for advanced laparoscopic skills. This paper presents a standardized and systematic approach to trans-abdominal pre-peritoneal (TAPP) groin hernioplasty, which is useful for training young surgeons. METHODS: The paper provides a detailed, step-by-step description of the TAPP based on evidence from literature, anatomical knowledge, and the authors' experience spanning over 30 years. The sample includes 487 hernia repair procedures, with 319 surgeries performed by experienced surgeons and 168 surgeries performed by young surgeons in training. The authors performed a descriptive analysis of their data to provide an overview of the volume of laparoscopic hernioplasty performed. RESULTS: The analysis of the data shows a low complication rate of 0.41% (2/487) and a low recurrence rate of 0.41% (2/487). The median duration of the surgery was 55 min, while the median operation time for surgeons in training was 93 min, specifically 83 min for unilateral hernia and 115 min for bilateral hernia. CONCLUSIONS: The TAPP procedure appears, to date, comparable to the open inguinal approach in terms of recurrence, postoperative pain and speed of postoperative recovery. In this paper, the authors challenge the belief that TAPP is not suitable for surgeons in training. They advocate for a training pathway that involves gradually building surgical skills and expertise. This approach requires approximately 100 procedures to achieve proficiency.

BACKGROUND: Robot-assisted transabdominal preperitoneal inguinal hernia repair (rTAPP-IHR) is a safe and feasible approach for hernias of varying etiology. We aim to present a single surgeon's learning curve (LC) of this technique based on operative times, while accounting for bilaterality and complexity. METHODS: This is a retrospective cohort analysis of patients who underwent rTAPP-IHR over a period of 5 years. Patients who underwent primary, recurrent, and complex (previous posterior repair, previous prostatectomy, scrotal, incarcerated) repairs were included. Cumulative and risk-adjusted cumulative sum analyses (CUSUM and RA-CUSUM) were used to depict the evolution of skin-to-skin times and complications/surgical site events (SSEs) with time, respectively. RESULTS: A total of 371 patients were included in the study. Mean skin-to-skin times were stratified according to four subgroups: unilateral non-complex (46.8 min), unilateral complex (63.2 min), bilateral non-complex (70.9 min), and bilateral complex (102 min). A CUSUM-LC was then plotted using each procedures difference in operative time from its subgroup mean. The peak of the plot occurred at case number 138, which was used as a transition between 'early' and 'late' phases. The average operative time for the late phase was 15.9 min shorter than the early phase (p < 0.001). The RA-CUSUM, plotted using the weight of case complexity and unilateral/bilateral status, also showed decreasing SSE rates after the completion of 138 cases (early phase: 8.8% vs. late phase: 2.2%, p = 0.008). Overall complication rates did not differ significantly between the two phases. CONCLUSIONS: Our study shows that regardless of bilateral or complex status, rTAPP operative times and SSE rates gradually decreased after completing 138 procedures. Previous laparoscopic experience, robotic team efficiency, and surgical knowledge are important considerations for a surgeon's LC.

BACKGROUND: Seroma/hematoma formation is the most common postoperative complication after laparoscopic inguinal hernia repair. The occurrence of seroma/hematoma remains unclear. The aim of this study was to determine the risk factors for seroma/hematoma formation after transabdominal preperitoneal patch plasty (TAPP). METHODS: The study enrolled 359 groin hernia patients treated by TAPP at Kumamoto Medical Center between 2014 and 2019. The primary outcome was risk factors for postoperative seroma/hematoma formation after TAPP. The secondary outcomes included recurrence of hernia, postoperative complications, and hospital stay. RESULTS: Among the 359 patients, the incidence rate of seroma/hematoma was 16% (n = 69 patients), and the recurrence rate was 0.3% (n = 1 patient, both sides). In total, there were 452 lesions. Japan Hernia Society (JHS) type II was present in 23% (n = 106) of the total cases but was significantly more common in the postoperative seroma/hematoma group (40%; P = 0.0082). Meanwhile, JHS type I-3 comprised 27% of the total JHS type I group but was significantly higher in the postoperative seroma/hematoma JHS type I group (40%; P = 0.016). Compared with JHS type I, the multivariable odds ratio for postoperative seroma/hematoma formation in JHS type II was 2.77 (95% CI 1.54-4.95). Compared with JHS grade 1/2, the multivariable odds ratio for postoperative seroma/hematoma formation in JHS grade 3 was 2.27 (95% CI 1.28-4.03). CONCLUSIONS: Internal inguinal hernia and hernia size ≥ 3 cm were considered risk factors for postoperative seroma/hematoma formation after TAPP.

BACKGROUND: An encysted spermatic cord hydrocele (ESCH) causes an inguinal swelling resembling an inguinal hernia (IH). An ESCH should be considered as a differential diagnosis of IH. Although laparoscopic operations have been performed to treat ESCHs in pediatric patients, such operations have not been reported in adults. This study was performed to evaluate the outcomes of laparoscopic hydrocelectomy for treatment of ESCHs in adults. METHODS: The medical charts of 49 patients who underwent laparoscopic transabdominal hydrocelectomy for ESCHs from January 2015 to December 2020 at a single institution were retrospectively reviewed. The patients were divided into those with and without an IH. Laparoscopic hydrocelectomy was performed, and the internal inguinal ring was closed with iliopubic tract repair (IPTR) or transabdominal preperitoneal (TAPP) hernioplasty depending on the presence of an IH. The patients' age, ESCH location, postoperative complications, recurrence, and operating time were examined. RESULTS: The patients' mean age was 46.7 (20-77) years. All patients underwent laparoscopic hydrocelectomy without open conversion. ESCHs were more common on the right side (35/49, 71.4%) than on the left (14/49, 28.6%). The presenting symptom in all patients was inguinal swelling. The ESCH was located inside the inguinal canal in 47 patients and protruded to the abdominal cavity from the inguinal canal in 2 patients. After laparoscopic hydrocelectomy, 32 patients without an IH underwent IPTR and 17 patients with an IH underwent TAPP hernioplasty. The mean operating time was shorter in the IPTR than TAPP hernioplasty group. The postoperative complications and hospital stay were not different between the two groups. There were no recurrences in either group. CONCLUSIONS: Laparoscopic hydrocelectomy with IPTR or TAPP hernioplasty is safe and feasible for treatment of ESCHs in adults.
