Chronic inguinal pain post-hernioplasty. Laparo-endoscopic surgery vs lichtenstein repair: systematic review and meta-analysis.

PURPOSE: Annually, over 20 million patients worldwide undergo inguinal hernia repair procedures. Surgery stands as the recommended treatment, however, a consensus on the optimal method is lacking. This study aims to conduct an updated systematic review and meta-analysis to compare the risk of chronic inguinal pain and recurrence between laparo-endoscopic mesh repair (TAPP and TEP) versus Lichtenstein repair for inguinal hernia. METHODS: Searches were conducted in Ovid MEDLINE, PubMed, EBSCO, Cochrane, and Google Scholar. Inclusion criteria encompassed randomized controlled trials (RCTs) involving adults, published in English and Spanish, comparing surgical outcomes among the Lichtenstein open technique, TAPP, and/or TEP. Adherence to the PRISMA guidelines was maintained in the methodology, and the CASP tool was employed to assess the quality of the articles. Statistical analysis involved mean [± standard deviation (SD)], Odds Ratio (OR), and Confidence Interval (CI). RESULTS: Eight RCTs encompassing 1,469 patients randomized to Lichtenstein repair (n = 755) and laparo-endoscopic repair (n = 714) were included. Laparo-endoscopic repair was associated with a lower likelihood of chronic inguinal pain compared to Lichtenstein repair (OR = 0.28, 95% CI [0.30-0.56], p = 0.0001). There were no significant differences in recurrence rates between the laparo-endoscopic and the Lichtenstein group (OR = 1.03, 95% CI [0.57-1.86], p = 0.92). CONCLUSIONS: This systematic review and meta-analysis demonstrate that laparo-endoscopic hernia surgery leads to a lower incidence of chronic inguinal pain compared to Lichtenstein repair, while maintaining similar rates of recurrence.

Women Are Also Disadvantaged in Accessing Transplant Outside the United States: Analysis of the Spanish Liver Transplantation Registry.

Sex inequities in liver transplantation (LT) have been documented in several, mostly US-based, studies. Our aim was to describe sex-related differences in access to LT in a system with short waiting times. All adult patients registered in the RETH-Spanish Liver Transplant Registry (2000-2022) for LT were included. Baseline demographics, presence of hepatocellular carcinoma, cause and severity of liver disease, time on the waiting list (WL), access to transplantation, and reasons for removal from the WL were assessed. 14,385 patients were analysed (77% men, 56.2 ± 8.7 years). Model for end-stage liver disease (MELD) score was reported for 5,475 patients (mean value: 16.6 ± 5.7). Women were less likely to receive a transplant than men (OR 0.78, 95% CI 0.63, 0.97) with a trend to a higher risk of exclusion for deterioration (HR 1.17, 95% CI 0.99, 1.38), despite similar disease severity. Women waited longer on the WL (198.6 ± 338.9 vs. 173.3 ± 285.5 days, p < 0.001). Recently, women's risk of dropout has reduced, concomitantly with shorter WL times. Even in countries with short waiting times, women are disadvantaged in LT. Policies directed at optimizing the whole LT network should be encouraged to guarantee a fair and equal access of all patients to this life saving resource.

Simultaneous pancreas-kidney transplantation: which graft warns the most?

BACKGROUND: Simultaneous pancreas-kidney transplantation (SPK) is still characterized by high rates of postoperative complications. This study aims to offer an in-depth characterization of early, medium-term, and late complications following SPK to derive insights for postoperative management and follow-up. METHODS: Consecutive SPK transplantations were analysed. Pancreatic graft (P-graft)- and kidney graft (K-graft)-related complications were analysed separately. The global postoperative course was assessed in three timeframes (early, medium-term, and late) using the comprehensive complication index (CCI). Predictors of complications and early graft loss were explored. RESULTS: Complications occurred in 61.2% of patients, and the 90-day mortality was 3.9%. The overall burden of complications was significantly high during admission (CCI 22.4 ± 21.1) and decreased gradually afterwards. P-graft-related complications burdened the most in the early postoperative course (CCI 11.6 ± 13.8); postoperative ileus and perigraft fluid collection were the most frequent complications, and pseudoaneurysms, haemorrhages, and bowel leaks were the major concerns. K-related complications were milder but represented the largest proportion of the CCI in the late postoperative timeframe (CCI 7.6 ± 13.6). No predictors of P-graft- or K-graft-related complications were found. CONCLUSION: Pancreas graft-related complications represent the largest part of the clinical burden in the early postoperative timeframe but are negligible after 3 months. Kidney grafts have a relevant impact in the long term. The multidisciplinary approach to SPK recipients should be driven based on all graft-specific complications and tailored on a time-dependent basis.

Appraising pancreatic fistula in pancreas transplantation: A comprehensive complication index based analysis of postoperative outcomes and predictors of graft survival.

BACKGROUND: A definition of pancreatic fistula specifically addressing pancreas transplantation (PT) is lacking. This study sought to characterize pancreatic fistula in this setting and to define its clinical relevance on the postoperative course and long-term graft survival (GS). METHODS: Consecutive simultaneous pancreas and kidney transplantations were analysed. The global postoperative course was assessed through the comprehensive complication index (CCI). PF was defined according to the original International Study Group for Pancreatic Surgery (ISGPS) definition. Predictors of poor postoperative course and GS were explored. RESULTS: Seventy-eight patients were analysed. Surgical morbidity was 48.7%, with severe complications occurring in 39.7%. Ninety-day mortality was 2.6%. PF occurred in 56.6% of patients, although its average clinical burden was low and did not correlate with either early or long-term outcomes. Peri-graft fluid collections, postoperative day (POD) 1 drain fluid amylase (DFA) ≥ 2200 U/L, and POD 5 DFA/serum amylase ratio ≥7.0 independently correlated with poor postoperative course. Perigraft fluid collections were associated with reduced GS. CONCLUSION: Conventionally defined pancreatic fistula is frequent following PT, although its clinical impact is negligible. To define clinically relevant PF, novel cut-offs for DFA might be pondered in a future series, while perigraft fluid collections should be strongly considered.

From conventional two-stage hepatectomy to ALPPS: Fifteen years of experience in a hepatobiliary surgery unit.

BACKGROUND: Hepatectomy in patients with large tumor load may result in postoperative liver failure and associated complications due to excessive liver parenchyma removal. Conventional two-stage hepatectomy (TSH) and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) technique are possible solutions to this problem. Colorectal liver metastases (CRLM) is the most frequent indication, and there is a need to assess outcomes for both techniques to improve surgical and long-term oncological outcomes in these patients. METHODS: A single-center retrospective study was designed to compare TSH with ALPPS in patients with initially unresectable bilateral liver tumors between January 2005 and January 2020. ALPPS was performed from January 2012 onwards as the technique of choice. Long-term overall survival (OS) and disease-free survival (DFS) were evaluated as primary outcome in CRLM patients. Postoperative morbidity, mortality and liver growth in all patients were also evaluated. RESULTS: A total of 38 staged hepatectomies were performed: 17 TSH and 21 ALPPS. Complete resection rate was 76.5% (n = 13) in the TSH group and 85.7% (n = 18) in the ALPPS group (P = 0.426). Overall major morbidity (Clavien-Dindo ≥ 3a) (stage 1 + stage 2) was 41.2% (n = 7) in TSH and 33.3% (n = 7) in ALPPS patients (P = 0.389), and perioperative 90-day mortalities were 11.8% (n = 2) vs. 19.0% (n = 4) in each group, respectively (P = 0.654). Intention-to-treat OS rates at 1 and 5 years in CRLM patients for TSH (n = 15) were 80% and 33%, and for ALPPS (n = 17) 76% and 35%, respectively. DFS rates at 1 and 5 years were 36% and 27% in the TSH group vs. 33% and 27% in the ALPPS group, respectively. CONCLUSIONS: ALPPS is an effective alternative to TSH in bilateral affecting liver tumors, allowing higher resection rate, but patients must be carefully selected. In CRLM patients similar long-term OS and DFS can be achieved with both techniques.

Number of Patients with Ischemic Stroke did not Decline in a Regional Stroke Unit After the Implementation of Mechanical Thrombectomy.

OBJECTIVES: Since the implementation of mechanical thrombectomy (MT) in 2015 for patients with ischemic stroke and large-vessel occlusion, the question arose as to whether patients should be primarily admitted to the nearest regional stroke unit (SU) for prompt intravenous thrombolysis (IVT) or to a more distant supraregional SU performing MT, to avoid secondary-transfer delays in MT. Although an evidence-based answer is still lacking, a discrepant discussion with potential consequences for the regional flow of stroke patients arose. We aimed to assess if MT implementation was associated with the number and characteristics of patients with stroke/transient ischemic attack (TIA) admitted to a regional SU not offering endovascular treatment. MATERIALS AND METHODS: Patients with acute stroke/TIA treated at the Klinikum Main-Spessart Lohr, Germany, in 2013/2014 or 2017/2018 were included in this retrospective study. Data were derived from the clinical information system and mandatory stroke quality assessment. We assessed the catchment area using a region-based approach. For each region, the number of patients treated in our hospital, including data regarding clinical severity, demographic characteristics, and changes over time, were analyzed. RESULTS: The number of patients with acute stroke/TIA increased from 890 (2013/2014) to 1016 (2017/2018). Aggregated demographic and clinical data of the whole catchment area showed no differences between 2013/2014 and 2017/2018 (P > 0.05) besides duration of hospitalization (P < 0.01), IVT rate (P < 0.01), and secondary transfer for MT. A region-based analysis revealed an increase in younger and more severely affected patients admitted from the periphery of the catchment area between 2013/2014 and 2017/2018. CONCLUSION: Despite the implementation of MT in the supraregional SUs around our regional SU (not offering MT), more patients with stroke/TIA were admitted to our hospital, especially younger and more severely affected patients, from the border regions of the catchment area.

Extended distal pancreatectomy with thoracic wall resection after neoadjuvant FOLFIRINOX: Is there a limit of resection for pancreatic cancer after downstaging?

Indications and outcomes of extended pancreatectomies have been recently appraised by the International Study Group for Pancreatic Surgery. However, no definitive conclusions have been drawn, particularly in the setting of neoadjuvant treatments. We present here a case of 53-year-old man diagnosed with a bulky adenocarcinoma of the tail of the pancreas and infiltrating the adjacent organs and the thoracic wall. The patient was sent to neoadjuvant chemotherapy and he underwent 12 cycles of FOLFIRINOX. Since a significant radiological response was observed after chemotherapy, the patient was scheduled for extended distal pancreatectomy with en bloc resection of the thoracic wall, in order to achieve a radical resection. The surgery is herein described with all technical details. The patient was discharged after an uneventful early post-operative course and subsequently readmitted for a late grade B post-operative pancreatic fistula, which was ultimately treated successfully. Pathology showed complete response. When performed in centers with ample experience in pancreatic surgery, extended pancreatic resections represent a viable curative option with acceptable surgical outcomes. In this setting, challenging tailored resections should be considered to achieve negative margins, particularly following maximized effective downstaging strategies.

Late complications of pancreas transplant.

To summarize the long-term complications after pancreas transplantation that affect graft function, a literature search was carried out on the long-term complications of pancreatic transplantation, namely, complications from postoperative 3rd mo onwards, in terms of loss of graft function, late infection and vascular complications as pseudoaneurysms. The most relevant reviews and studies were selected to obtain the current evidence on these topics. The definition of graft failure varies among different studies, so it is difficult to evaluate, a standardized definition is of utmost importance to know the magnitude of the problem in all worldwide series. Chronic rejection is the main cause of long-term graft failure, occurring in 10% of patients. From the 3rd mo of transplantation onwards, the main risk factor for late infections is immunosuppression, and patients have opportunistic infections like: Cytomegalovirus, hepatitis B and C viruses, Epstein-Barr virus and varicella-zoster virus; opportunistic bacteria, reactivation of latent infections as tuberculosis or fungal infections. Complete preoperative studies and serological tests should be made in all recipients to avoid these infections, adding perioperative prophylactic treatments when indicated. Pseudoaneurysm are uncommon, but one of the main causes of late bleeding, which can be fatal. The treatment should be performed with radiological endovascular approaches or open surgery in case of failure. Despite all therapeutic options for the complications mentioned above, transplantectomy is a necessary option in approximately 50% of relaparotomies, especially in life-threatening complications. Late complications in pancreatic transplantation threatens long-term graft function. An exhaustive follow-up as well as a correct immunosuppression protocol are necessary for prevention.

Hiperplasia estromal seudoangiomatosa. Una lesión de la mama infrecuente y de presentación variable / Pseudoangiomatous stromal hyperplasia. A rare breast lesion with variable presentation

La hiperplasia estromal seudoangiomatosa es una lesión mamaria poco frecuente y de carácter benigno. Se caracteriza por un sobrecrecimiento de tejido conectivo fibroso que produce numerosos espacios que semejan estructuras vasculares. Generalmente afecta a mujeres en edad reproductiva, aunque se ha descrito en pacientes de edades comprendidas entre los 12 y los 75 años. Puede presentarse bien como un hallazgo incidental en el estudio histológico tras una cirugía por patología benigna o maligna, bien como una tumoración mamaria indolora, simulando un fibroadenoma, o bien como una gigantomastia o deformidad que se hace más evidente al tener en cuenta la mama contralateral. La biopsia percutánea guiada por ecografía permite detectar la naturaleza de la lesión con certeza y descartar patología maligna, como el angiosarcoma de bajo grado. El tratamiento es quirúrgico y abarca tanto la exéresis quirúrgica de la lesión como la mastectomía con reconstrucción protésica. Se describe una serie de 3 casos con diferente presentación clínica y tratamiento. El primer caso fue un hallazgo radiológico e histopatológico relacionado con una deformidad y asimetría mamarias, mientras que los 2 últimos casos se manifestaron como una tumoración mamaria palpable, única e indolora (AU)

Pseudoangiomatous stromal hyperplasia is a rare benign mammary lesion. It is characterised by an overgrowth of fibrous connective tissue that produces numerous spaces resembling vascular structures. This lesion usually affects women of reproductive age but has been described in patients aged between 12 and 75 years. It may appear as an incidental finding in histological analysis after surgery for benign or malignant disease, either as a painless breast tumour, simulating a fibroadenoma, or as a gigantomastia or deformity that becomes more evident on comparison with the contralateral breast. Percutaneous ultrasound-guided biopsy allows definitive identification of the type of lesion and exclusion of malignant disease, such as low-grade angiosarcoma. Treatment is surgical and includes both surgical removal of the lesion and mastectomy with prosthetic reconstruction. We describe a series of three cases with different clinical presentations and treatment. The first case was a radiological and histopathological finding related to a breast deformity and asymmetry, while the remaining two cases presented as a palpable, single and painless breast tumour (AU)

Primary peripancreatic lymph node tuberculosis as a differential diagnosis of pancreatic neoplasia.

Primary peripancreatic lymph node tuberculosis is an exceptional entity in immunocompetent patients, but its incidence is increasing in developed countries in recent years due to increasing immigration. It usually presents as a pancreatic mass and is misdiagnosed as pancreatic neoplasia in most cases, with the diagnosis of tuberculosis occurring after surgery. We report the case of a 38 year old Pakistani man with abdominal pain of several months duration, who was initially diagnosed with a pancreatic neoplasm after detecting a mass in the pancreatic isthmus by computed tomography (CT) and abdominal magnetic resonance imaging (MRI). However, after performing an endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB), the patient was diagnosed with peripancreatic lymph node tuberculosis. After receiving anti-tuberculous treatment, the patient presented clinical improvement, despite a small reduction in the lesion size. In conclusion, peripancreatic lymph node tuberculosis is part of the differential diagnosis of pancreatic neoplasia. Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNAB) represents a valuable and useful diagnostic tool for detecting this pathology, avoiding surgeries with a high morbidity and mortality.

ALPPS monosegmento: una nueva variante de las técnicas de regeneración hepática rápida. Revisión crítica de los resultados iniciales de nuestra serie / Monosegment ALPPS: A new variant of the techniques for rapid hepatic regeneration. Critical review of the initial results of our series

La hepatectomía secuencial, descrita en la literatura anglosajona con el acrónimo ALPPS (Associating Liver Partition and Portal vein ligation for Staged hepatectomy) es una técnica novedosa que ofrece un crecimiento rápido y efectivo del volumen remanente hepático, y que permite la resección quirúrgica de lesiones hepáticas consideradas inicialmente irresecables. Los resultados a corto y largo plazo y la conveniencia de realizar esta técnica son cuestiones que permanecen en discusión a la espera de los resultados finales de los registros multicéntricos. El objetivo del presente trabajo es la revisión crítica de los resultados de la serie de casos realizados en nuestro centro (n = 8). Por otra parte, es posible con esta técnica dejar un único segmento hepático como remanente y realizamos una descripción de esta variante técnica novedosa (ALPPS monosegmento), llevada a cabo en uno de los casos

Associating Liver Partition and Portal vein ligation for Staged hepatectomy (ALPPS) is a novel surgical technique that provides fast and effective growth of liver remnant volume, allowing surgical resection of hepatic lesions initially considered unresectable. Short and long-term results and the convenience of carrying out this technique are issues that still remain under debate while waiting for the final outcomes of the multicenter registries with larger number of cases. The aim of this paper is to describe, from a critical point of view, the outcomes of the cases performed at our center (n = 8). On the other hand, it is possible to leave only one hepatic segment as a liver remnant and we illustrate this new surgical procedure (ALPPS monosegment) performed in one patient

Metastasis of the gallbladder in clear cell renal carcinoma.

Metastasis of the gallbladder due to renal cell tumors is rare. We present a case of gallbladder and metachronous left adrenal metastasis at six months follow-up, which demonstrates the importance of radiological tests and histology when making a definitive diagnosis. Clinical findings are not specific enough to arrive at a final diagnosis. However, immunohistochemistry is necessary to differentiate between primary and secondary metastatic tumors. Cholecystectomy should be performed to obtain a definitive diagnosis and to improve survival in cases of single lesions in the gallbladder.
