ABSTRACT
INTRODUCTION: There has been a rapid proliferation of the robotic approach to inguinal hernia, mainly in the United States, as it has shown similar outcomes to the laparoscopic approach but with a significant increase in associated costs. Our objective is to conduct a cost analysis in our setting (Spanish National Health System). MATERIALS AND METHODS: A retrospective single-center comparative study on inguinal hernia repair using a robotic approach versus laparoscopic approach. RESULTS: A total of 98 patients who underwent either robotic or laparoscopic TAPP inguinal hernia repair between October 2021 and July 2023 were analyzed. Out of these 98 patients, 20 (20.4%) were treated with the robotic approach, while 78 (79.6%) underwent the laparoscopic approach. When comparing both approaches, no significant differences were found in terms of complications, recurrences, or readmissions. However, the robotic group exhibited a longer surgical time (86 ± 33.07 min vs. 40 ± 14.46 min, p < 0.001), an extended hospital stays (1.6 ± 0.503 days vs. 1.13 ± 0.727 days, p < 0.007), as well as higher procedural costs (2318.63 ± 205.15 vs. 356.81 ± 110.14 , p < 0.001) and total hospitalization costs (3272.48 ± 408.49 vs. 1048.61 ± 460.06 , p < 0.001). These results were consistent when performing subgroup analysis for unilateral and bilateral hernias. CONCLUSIONS: The benefits observed in terms of recurrence rates and post-surgical complications do not justify the additional costs incurred by the robotic approach to inguinal hernia within the national public healthcare system. Nevertheless, it represents a simpler way to initiate the robotic learning curve, justifying its use in a training context.

BACKGROUND: The aim of this study was to analyze the strength status of the rectus abdominis muscle in patients with incisional hernia and the relationship between the width of the hernia defect and the strength of the rectus abdominis muscle. METHODS: This is a observational cohort study of patients with medial line incisional hernia (July-October 2022), classified as W2 according to the European Hernia Society (EHS). The data collected were demographic and clinical characteristics related to hernia, and measure of the rectus abdominis muscle strength using an isokinetic dynamometer and a strain gauge. We analyzed the relationship between hernia width and rectus abdominis muscle strength with correlation tests to adjustment by age, sex, BMI, and body composition. RESULTS: A total of 40 patients (64% female) with a mean age of 57.62 years (SD 11) were enrolled in the study. The mean BMI was 29.18 (SD 5.06), with a mean percentage of fat mass of 37.8% (SD 8.47) and a mean percentage of muscle mass of 60.33% (SD 6.43). The maximum width of the hernia defect was 6.59 cm (SD 1.54). In the male group, the mean bending force moment (ISOK_PT) was 94.01 Nw m (SD 34.58), bending force moment relative to body weight (ISOK_PT_Weight) was 103.32 Nw m (SD 37.48), and peak force (PK_90) was 184.71 N (SD 47.01). In the female group, these values were 58.11 Nw m (SD 29.41), 66.48 Nw m (SD 32.44), and 152.50 N (SD 48.49), respectively. Statistically significant differences were observed in the relationship between the data obtained with the isokinetic dynamometer and sex (p = 0.002), as well as between the data obtained with the isokinetic dynamometer and age (p = 0.006). Patients in the 90th percentile (P90) of rectus abdominis muscle strength also had smaller hernia defect widths (p = 0.048). CONCLUSIONS: In this study, age and sex were identified as the most statistically significant predictor variables for rectus abdominis muscle strength. The width of the hernia defect exhibited a trend towards statistical significance.

PURPOSE: There is a growing trend to expand Ambulatory Surgery (AS) criteria in abdominal wall surgery. No Admission (NOADS) circuit. The present study aimed to assess the impact of classification criteria on postoperative results and hospital stays in a NOADS versus a conventional admission circuit to throw some light on surgical circuit inclusion. METHODS: A retrospective analysis of a prospective;y maintained database was performed comparing groin hernia's interventions in a NOADS vs Admission circuit in our center in 2018-2021. A multiple regression predictive model followed by a retrospective retest were dessigned to assess the impact of each criterion on hospital stay. In total, 743 patients were included, 399 in the Admission circuit (ADC) and 344 in NOADS circuit (NOADS). RESULTS: There were no statistical differences in complication or readmission rates (p = 0.343 and p = 0.563), nevertheless, a shorter hospital stay was observed in NOADS (p = 0.000). A hierarchical multiple regression predictive model proposed two opposite scenarios. The best scenario, not likely to need admission, was a female patient operated via the laparoscopic approach of a unilateral primary hernia (Estimated Postoperative Stay: 0.049 days). The worst scenario, likely to need admission, was a male patient operated via the open approach of a bilateral and recurrent hernia (Estimated Postoperative Stay: 1.505 Days). CONCLUSION: Groin hernia patients could safely benefit from a No Admission (NOADS) circuit. Our model could be useful for surgical circuit decision-making, especially for best/worst scenarios.

PURPOSE: The use of mesh is a common practice in ventral hernia repair (VHR). Lack of consensus on which prosthetic material works better in different settings remains. This meta-analysis aims to summarize the available evidence on hernia recurrence and complications after repair with synthetic, biologic, or biosynthetic/bioabsorbable meshes in hernias grade 2-3 of the Ventral Hernia Working Group modified classification. METHODS: A literature search was conducted in January 2021 using Web of Science (WoS), Scopus, and MEDLINE (via PubMed) databases. Randomized Controlled Trials (RCTs) and observational studies with adult patients undergoing VHR with either synthetic, biologic, or biosynthetic/bioabsorbable mesh were included. Outcomes were hernia recurrence, Surgical Site Occurrence (SSO), Surgical Site Infection (SSI), 30 days re-intervention, and infected mesh removal. Random-effects meta-analyses of pooled proportions were performed. Quality of the studies was assessed, and heterogeneity was explored through sensitivity analyses. RESULTS: 25 articles were eligible for inclusion. Mean age ranged from 47 to 64 years and participants' follow-up ranged from 1 to 36 months. Biosynthetic/bioabsorbable mesh reported a 9% (95% CI 2-19%) rate of hernia recurrence, lower than synthetic and biologic meshes. Biosynthetic/bioabsorbable mesh repair also showed a lower incidence of SSI, with a 14% (95% CI 6-24%) rate, and there was no evidence of infected mesh removal. Rates of seroma were similar for the different materials. CONCLUSIONS: This meta-analysis did not show meaningful differences among materials. However, the best proportions towards lower recurrence and complication rates after grade 2-3 VHR were after using biosynthetic/slowly absorbable mesh reinforcement. These results should be taken with caution, as head-to-head comparative studies between biosynthetic and synthetic/biologic meshes are lacking. Although, biosynthetic/bioabsorbable materials could be considered an alternative to synthetic and biologic mesh reinforcement in these settings.

PURPOSE: The implantation of non-absorbable meshes is the gold standard technique for ventral hernia (VH) repairs. However, emergency surgeries are often related to contaminated/infected fields, where the implantation of prosthetic materials may not be recommendable. Our aim was to evaluate the results of polyvinylidene fluoride (PVDF) meshes used for contaminated and/or complicated VH repairs in the acute setting. METHODS: We conducted a retrospective analysis of patients with VH who underwent emergency surgery involving PVDF meshes, in a tertiary hospital (from November 2013 to September 2019). We analyzed postoperative complications and 1-year recurrence rates. We evaluated the relationships between contamination grade, mesh placement, infectious complications, and recurrences. RESULTS: We gathered data on 123 patients; their mean age was 62.3 years, their mean BMI was 31.1 kg/m2, and their mean CeDAR index was 51.6. 96.4% of patients had a grade 2-3 ventral hernia according to the Rosen index. The mean defect width was 8 cm (IQR 2-18). 93 cases (75.6%) were described as contaminated or dirty surgeries. A PVDF mesh was placed using an IPOM technique in 56.3% of cases, and via interposition location in 39.9%. The one-month recurrence rate was 5.7% and recurrence after one year was 19.1%. The overall mortality rate was 27.6%. Risk of recurrence was related to patients with a Rosen score over 2 (p < 0.001), as well as with postoperative SSI (p = 0.045). Higher recurrence rates were not related to PVDF mesh placement. CONCLUSION: The use of PVDF meshes for emergency VH repairs in contaminated surgeries seems safe and useful, with reasonable recurrence rates, and acceptable infectious complication rates, similar to those published in the literature.

Chylous ascites is a rare condition little reported in literature, with even more exceptional traumatic origin. Its production mechanism is not known exactly but has been attributed to hyperflexion or hyperextension of the spine leading to a rupture of lymph ducts. We present a case of post-traumatic chyloperitoneum in a young patient after abdominal blunt trauma. Conservative treatment should be the first therapeutic option, especially if the origin is traumatic, reserving more aggressive possibilities for cases that do not respond after 15 days, if debt is greater than 1.5 litres/day in adult patients or in those with metabolic complications. A laparoscopic approach is indicated to confirm the diagnosis and to rule out other associated injuries that may require other surgical procedures.

PURPOSE: The aim of this study was to analyze our experience with portal vein thrombosis after liver transplantation with a persistent splenorenal shunt. MATERIALS AND METHODS: The study population included 780 liver transplantations from 1990 to 2009. We analyzed the existence of portal vein thrombosis in the immediate posttransplant period, selecting cases with a persistent splenorenal shunt requiring surgery. RESULTS: The incidence of posttransplant portal vein thrombosis was 1.41% (n=11), of which 3 (27%) had a splenorenal shunt as a possible cause (0.38% of the total). Two cases required liver retransplantation due to portal vein thrombosis, and the third a thrombectomy. In all cases the shunt was also closed. During the early postoperative follow-up of these 3 patients, 2 needed repeat surgeries because of a new portal vein thrombosis (thrombectomy) in one and a bilioperitoneum in the other. After a median follow-up of 11 months, the patients showed a good evolution with no primary graft dysfunction. DISCUSSION: The portal steal phenomenon secondary to persistence of a splenorenal shunt promotes the occurrence of portal vein thrombosis. Although it is a rare cause of graft dysfunction, it must be treated early, because it can lead to a small-for-size syndrome.

OBJECTIVE: Our aim was to safely and effectively reduce adverse gastrointestinal (GI) events resulting from the use of mycophenolate mofetil (MMF) in liver transplant patients by switching to enteric-coated mycophenolate sodium (EC-MPS). PATIENTS AND METHODS: We studied 19 patients on maintenance therapy presenting with GI intolerance to MMF whose therapy was switched to EC-MPS. The variables recorded were: calcineurin inhibitor (CNI) dose levels, MMF/EC-MPS dose levels, lipid profile, hematology, renal and hepatic function markers, and rejection episodes. These variables were recorded at the visit prior to the day of conversion, on the day of conversion, and 1, 3, 6, and 9 months thereafter. RESULTS: Of the 19 patients, 16 were men (mean age, 56.6 +/- 15.9 years) and 3 were women (58.3 +/- 12.1 years). While 31.6% were on MMF monotherapy, 52.6% were on combined therapy with tacrolimus and 15.8% with cyclosporine. On the day of conversion, 21% were not on MMF, 36.8% were on 1000 mg/d, 26.3% were on 1500 mg/d, 5.3% were on 750 mg/d, and 10.6% were on 500 mg/d. The starting daily doses of EC-MPS were: 360 mg (26.3%), 720 mg (31.6%), 540 mg (26.3%), 1080 mg (10.5%), and 1440 mg (5.3%). GI complications were significantly reduced from the first month postconversion (P < .01), as 57.2% of patients did not display any symptoms; however, at 9 months, this incidence rose by 12% relative to month 1 (P < .05). There were no changes in the other variables and there were no reported rejection episodes. Treatment was suspended in 2 patients due to dyspnea and nervousness. CONCLUSION: In liver transplant patients with GI complications from chronic MMF use, the use of EC-MPS was safe and efficacious, as it significantly reduced their incidence.

INTRODUCTION: Liver transplant recipients suffer a high risk of developing cancer, mainly as a consequence of immunosuppressant treatment, although a variety of other factors are involved. Our purposes were to evaluate the frequency of de novo tumours and to determine predisposing factors. MATERIAL AND METHODS: We analyzed all of the transplantations performed during 1990, with a total of almost 700 cases. We analyzed the frequency of de novo tumors, their location, time since transplantation, survival, and recurrence rates and factors that may influence their appearance. RESULTS: The series included 64 cases in 50 patients with a frequency of 7%. Skin tumors were the most frequent (39.06%), followed by those in the otolaryngologic (ear, nose, and throat) region (15.62%) and the lung (14.06%). The average time to progression between the transplantation and diagnosis was less than 4 years (47.74 months). The recurrence rate was 16%. The factors with the greatest influence on their appearance were age and gender of the recipient, alcohol consumption, and Child-Pugh score. Plasma transfusion was statistically, although not clinically, significant. DISCUSSION: Our frequency of de novo tumors was consistent with that described in the literature. Despite some factors that influence their appearance, the main predisposing factor was immunosuppression and its duration.

Caroli's disease is a rare condition that includes fibrocystic malformations of the bile duct. It consists of multifocal congenital dilatations of the intrahepatic bile ducts, which may be diffuse or limited, presenting in sack form that produces cystic structures which communicate with the biliary tree. Herein we have presented the case of a 44-year-old woman with recurrent cholangitis consequential to Caroli's syndrome. The distinctive feature of this case was that it was the first and only liver transplantation performed to date for this cause at our center among 700 procedures that had been performed over 19 years. The hepatectomy sample from the liver transplantation showed large cystic dilatations at the level of segments VII and VIII. The pathological study reported congenital dilatation of the intrahepatic bile ducts, associated with congenital hepatic fibrosis (Caroli's syndrome). Caroli's syndrome is a complex association of conditions which usually presents together with polycystic kidney lesions. Orthotopic liver transplantation is still the only therapeutic option for diffuse, uncontrollable cases or those with significant portal hypertension, as well as being the final option in the other cases in the event of a lack of response to other therapeutic options or as an alternative to them.

Cirrhosis secondary to hepatitis C virus (HCV) is one of the most frequent indications for liver transplantation. During recent years, the age of donors has increased, which has led to a worse prognosis for persons undergoing transplantations because of this virus. In this study, we analyzed the 93 transplantations performed during a 6-year period (2000-2005) due to HCV, dividing them into 2 groups according to donor age: <60 years (group A) and >/=60 years (group B). We examined graft and recipient survivals with a mean follow-up of 34 months. Recipient survival among group A was 61% compared with 57% among Group B, the difference being greater if we excluded the initial months after transplantation, since this eliminated the complications inherent to the intervention. Graft survival, according to the Knodell histological activity index, was summarized as: 55.7% histological recurrence, 16.7% fibrosis, and 21% cirrhosis among group A versus 65.6%, 25%, and 18.7%, respectively, among group B. In conclusion, there was improved survival and disease progression was slower among group A compared with group B, suggesting that donor age was an important factor; patient and graft survivals fell progressively with increased donor age.
