ABSTRACT

Retroperitoneal cystic lymphangiomas (RCL) are rare benign tumors of the lymphatic system. They account for less than 1% of all lymphangiomas. Surgical resection is the recommended treatment option; however, obtaining a pre-operative diagnosis is often difficult and, in most cases, the final diagnosis is only possible following histological assessment of the surgical specimen. This report describes a case of RCL in a 58-year-old female cirrhotic patient who presented to our center with dull aching abdominal pain and distension. To our knowledge, this is the first case of a RCL in a cirrhotic patient reported in the literature.

Los linfangiomas quísticos retroperitoneales (LQR) son tumores benignos raros del sistema linfático y representan menos del 1% de todos los linfangiomas. La resección quirúrgica es la opción de tratamiento recomendada; sin embargo, obtener un diagnóstico preoperatorio suele ser difícil y, en la mayoría de los casos, el diagnóstico final solo es posible tras la evaluación histológica de la pieza operatoria. En este estudio, describimos un caso de un LQR en una paciente cirrótica de 58 años que se presentó en nuestro centro con dolor abdominal sordo y distensión. Hasta donde sabemos, este es el primer caso de LQR en un paciente cirrótico reportado en la literatura.

ABSTRACT

Cholecystocholedocholithiasis is a common disease worldwide; however, there is still no consensus regarding a gold standard therapy for its management. Nowadays, the preferred method is a "two-step" process, starting with an endoscopic common bile duct (CBD) stone extraction (endoscopic retrograde cholangiopancreatography [ERCP]) followed by a laparoscopic cholecystectomy (LC). Nevertheless, this "two-step" approach has shown some difficulties over time (i.e., need for two hospital admissions, need of at least two anesthesia inductions, higher rate of post-procedural pancreatitis, longer hospitalizations and thus, increased costs). On the other hand, the laparo-endoscopic rendezvous (LER), which is a simultaneous combined procedure for removing the gallbladder laparoscopically and clearing the CBD endoscopically, is another valid treatment modality that involves a "single-step" resolution of cholecystocholedocholithiasis applying a multidisciplinary approach of the patient. The aim of this study was to present our initial outcomes. We retrospectively analyzed eleven patients who consecutively underwent LER at our institution from May 2017 to March 2022. The patients' mean age was 50.6 years old (range, 34 - 68) and most were male 54.5% (6/11). LER successfully achieved CBD stone clearance in 90.9% (10/11) of the cases. Post-LER pancreatitis was not recorded in any case. Post-operative complications included one reoperation (1/11; 9.1%) due to bleeding from one of the laparoscopic trocar sites. Our group concluded that LER can be effectively applied in Perú with good mid-term results and confirmed its effectiveness in accomplishing CBD stone clearance. Based on our results, we recommend the use of LER as a safe and valid therapeutic option for our patients.


La colecistocoledocolitiasis es una enfermedad común a nivel mundial; sin embargo, aún no hay ningún consenso sólido acerca de una sola "terapia ideal" para su manejo. Hoy en día, el método mas utilizado es un procedimiento que involucra "dos estadios", el cual comienza con la extracción endoscópica de cálculos del conducto biliar común (CBD) (colangiopancreatografía retrógrada endoscópica [CPRE]) seguida de una colecistectomía laparoscópica (CL). Sin embargo, este enfoque de "dos estadios" ha mostrado algunas desventajas con el tiempo (necesidad de dos ingresos hospitalarios, necesidad de al menos dos inducciones anestésicas, mayor tasa de pancreatitis post-procedimiento, hospitalizaciones más prolongadas y, por lo tanto, mayores costos). Por otra parte, el rendezvous laparo-endoscópico (RLE), es otra modalidad de tratamiento que implica la resolución en "un solo paso" de la colecistocoledocolitiasis, aplicando un enfoque multidisciplinario hacia el paciente. El RLE es un procedimiento en el cual simultáneamente se realizan la CL y la extracción de cálculos coledocianos por vía endoscópica. El objetivo de este estudio fue presentar nuestros resultados iniciales. Analizamos retrospectivamente once pacientes que fueron intervenidos quirúrgicamente mediante la técnica de RLE en nuestra institución desde mayo de 2017 hasta marzo de 2022. La edad media de los pacientes fue de 50,6 años (rango de edad, 34 - 68) y la mayoría fueron varones 54,.5% (6/11). RLE logró eliminar con éxito los cálculos de CBD en el 90,9 % (10/11) de los casos. En ningún caso se registró pancreatitis post-RLE. Las complicaciones postoperatorias incluyeron una reintervención (1/11; 9,1%) por sangrado de uno de los trócares laparoscópicos. Nuestro grupo concluyó que la técnica RLE se puede aplicar de manera efectiva en Perú con buenos resultados a mediano plazo y confirmó su efectividad para lograr la eliminación de cálculos de CBD. En base a nuestros resultados, recomendamos el uso de RLE como una opción terapéutica segura y válida para nuestros pacientes.

ABSTRACT

Portal vein thrombosis (PVT) is a rare condition in the general population that develops serious complications if left untreated for long time. We present a case of a 29-year-old woman who developed PVT due to protein S deficiency versus neonatal funiculitis. Over time, the patient developed upper gastrointestinal bleeding due to esophageal varices and hypersplenism with splenic sequestration that caused minor bleeding episodes. Laparoscopic splenectomy and proximal splenorenal shunt with distal pancreatectomy due to aneurysmal dilatations of the splenic artery were successfully performed to avoid mayor progression of portal hypertension. Patient was discharged with indefinite anticoagulation and after surgery platelets raised up to 200x103/mm3. Laparoscopic splenectomy and proximal splenorenal shunt for portal hypertension due to portal vein thrombosis is an adequate surgery procedure which should be applied in these medical cases.

La trombosis de la vena porta (TVP) es una afección poco común en la población general que desarrolla complicaciones graves si no se trata durante mucho tiempo. Presentamos el caso de una mujer de 29 años que desarrolló TVP por deficiencia de proteína S versus funiculitis neonatal. Con el tiempo, la paciente desarrolló hemorragia digestiva alta por varices esofágicas e hiperesplenismo con secuestro esplénico que provocó episodios hemorrágicos menores. La esplenectomía laparoscópica y la derivación esplenorrenal proximal con pancreatectomía distal por dilataciones aneurismáticas de la arteria esplénica se realizaron con éxito para evitar una mayor progresión de la hipertensión portal. La paciente fue dada de alta con anticoagulación indefinida y tras la cirugía se elevaron las plaquetas hasta 200x103/mm3. La esplenectomía laparoscópica y la derivación esplenorrenal proximal para la hipertensión portal por trombosis de la vena porta es un procedimiento quirúrgico adecuado que debe aplicarse en estos casos médicos.

ABSTRACT

BACKGROUND: Pediatric kidney transplantation (PKTx) is the preferred therapy for children with end-stage renal disease (ESRD) worldwide. Regrettably, in Perú, access to PKTx is extremely difficult due to recipient/donor socio-economic status, health care structure and especially, scarcity of organs. Our center (the only pediatric institute in the country) has recently started a PKTx program with good midterm results. The aim of this study was to present our outcomes. METHODS: Retrospective analysis of prospectively collected data between December 2017 and August 2019. Fourteen PKTx (< 18 years old) were achieved. As per our protocol: pre-implantation/protocol biopsies, antibody assessment (T/B cell flow cytometric plus HLA testing applying polymerase chain reaction-based technology), triple immunosuppression (tacrolimus, mycophenolate mofetil, steroids) and induction therapy was performed in every case. RESULTS: The recipient's mean age at the time of PKTx was 14.14 ± 2.62, 8/14 (57.14%) were male, 50% developed ESRD due to undetermined etiology, 11/14 (78.57%) received a deceased donor allograft, and 9/14 (64.28%) required induction with thymoglobulin. Postoperative complications included: delayed graft function (1/14, 7.14%), 1 (7.14%) developed gross hematuria associated with allograft disfunction post-protocol allograft biopsy that was managed conservatively and 1 recipient (7.14%) developed grade II oligoastrocytoma, at 10 months post PKTx. CONCLUSIONS: PKTx is the best therapeutic option for children with ESRD. Our group demonstrated that even in countries with limited resources like Perú, good midterm results can be achieved. Emphasis should be given to improve access to transplantation especially in the setting of pediatric recipients.

ABSTRACT

BACKGROUND: We previously showed that bortezomib (BTZ) partially depletes plasma cells, yet has limited efficacy for desensitization in kidney transplant candidates when up to 16 doses is given. METHODS: This study aimed to determine the safety and efficacy of 32 doses of BTZ (1.3 mg/m of body surface area) in 10 highly sensitized kidney transplant candidates with alloantibodies against their intended living donor. RESULTS: Dose reduction was needed in 2 patients and 2 others completely discontinued therapy for adverse events. Anti-HLA antibodies mean fluorescence intensity (MFI) values were stable prior to BTZ (P = 0.96) but decreased after therapy (mean decrease of 1916 [SE, 425] MFI, P < 0.01). No patient developed a negative crossmatch against their original intended donor, and the calculated panel-reactive antibodies based on MFI of 2000, 4000, and 8000 was unchanged in all patients. CONCLUSIONS: These data suggest that 32 doses of BTZ monotherapy was not well tolerated and resulted in only a modest reduction in anti-HLA antibodies.

ABSTRACT

Renal retransplantation after a failed prior kidney and pancreas transplant is being increasingly performed. In these complex cases, both iliac fossae have been used for prior transplants, and the placement of the new allograft can be problematic. We describe our experience with an alternative technique for renal retransplantation (RRTx) in the setting of severe bilateral aortoiliac atherosclerosis or scarring and fibrosis on the iliac vessels. Nephrectomy of the failed allograft is performed, and the renal vessels of the failed allograft (RVFA) are preserved. The new kidney is implanted on RVFA at the same operative time. This technique was attempted and successfully accomplished in a total of six patients (mean operative time = 240 ± 63 min). One postoperative complication occurred: poor arterial inflow to the allograft, being corrected reoperatively. Hospitalizations ranged from five to eight d. Five of the six patients were alive with a functioning allograft at last follow-up (a single graft failure occurred 21 months postoperatively in the setting of post-transplant lymphoproliferative disease that also led to patient death). Renal vessels of the failed allograft seem to be suitable alternative vascular conduits for renal retransplantation after prior kidney and pancreas transplants.
