Neonatal Intracranial Pial Arteriovenous Fistula Treated with Endovascular Embolization: A Case Report.

BACKGROUND: Pial arteriovenous fistulas (PAVFs) are rare vascular malformations, especially in neonates. The purpose of this report is to discuss the treatment strategy and its associated challenges. We present a case of prenatal intracranial PAVF treated by endovascular embolization in the neonatal period. CASE DESCRIPTION: The patient was born through Cesarean delivery and then treated twice using transarterial embolization with detachable platinum coils and n-butyl cyanoacrylate due to intractable heart failure. Even though angiography findings showed dramatical reduction in the shunt, the patient did not recover from heart failure and died at day 49 after birth. CONCLUSIONS: Despite current developments in medical technology and therapies, the effective treatment of critical PAVFs still poses a challenge. Therefore, more indications and effective alternative treatments must be discussed.

Single-stage laparoscopic surgery for bilateral organ tumors using a transumbilical approach with a zigzag incision: a report of two cases.

BACKGROUND: Reduced port laparoscopic surgery (RPLS) is comparable to conventional multiport laparoscopic surgery and has the potential to provide improved cosmesis and decreased pain; as such, it satisfies a growing demand for less invasive surgical procedures. Moreover, a zigzag incision of the umbilicus results in a less visible scar in plastic surgery. Here we report a series of two cases with bilateral organ tumors treated by single-stage RPLS using a combination of a transumbilical approach and a zigzag incision. CASE PRESENTATION: Case 1: A 63-year-old man was diagnosed with right renal cell carcinoma (RCC) (clear cell carcinoma, pT1a, venous invasion (-)) and a splenic tumor (cavernous hemangioma). Case 2: An 84-year-old woman was diagnosed with concurrent left RCC (clear cell carcinoma, pT1b, 65 × 65 mm, venous invasion (+)) and ascending colon cancer (adenocarcinoma pT3 with no nodal involvement (0/48)). The perioperative course was uneventful in both cases. However, an additional incision was required in Case 2 for specimen excision. Therefore, the scars were more obvious in Case 2 than in Case 1. CONCLUSIONS: Although more cases are required to evaluate the superiority of this technique, this novel procedure could be considered for patients with bilateral lesions.

The experience of transumbilical endoscopic appendectomies.

Minimally invasive surgery is being widely accepted in various fields of surgery. Although several appendectomy techniques have been reported but, there is no standardization. We report here the experiences of transumbilical endoscopic appendectomy in humans. Between July 2008 and September 2010, ten patients with appendicitis successfully underwent transumbilical endoscopic appendectomies. There were 7 cases of suppurative, 2 cases of gangrenous and 1 case of perforated in operative findings. The ages of the patients were 13-56 years (mean age, 32.7 ± 15.4 years). Under general anesthesia, a 15-mm port was inserted through the umbilicus and then a two-channel endoscope was inserted in the peritoneal cavity. After appendix identification, counter-traction of the appendix with a direct abdominal wall puncture using a straight round needle prolene was performed to achieve good visualization of the operative field. Tissue dissection was performed using an endoscopic needle knife. Tissue grasping and resected appendix retrieval were done with endoscopic forceps. The average operation time was 79.5 ± 23.6 minutes (range, 45 to 110 minutes). No procedures were converted to laparoscopic or open appendectomy. Hospital stay was 4-6 days. All patients completely recovered without complications. As it is highly maneuverable, we believe transumbilical endoscopic appendectomy can be a feasible method. And, as surgeons want to proceed from laparoscopic surgery to natural orifice transluminal endoscopic surgery, this procedure could be a triable method.

Results of the first 100 single port laparoscopic cholecystectomies in a secondary care hospital.

INTRODUCTION: Despite the excellent results obtained with standard laparoscopic cholecystectomy, the efforts for minimizing the ports needed to reduce postoperative pain, for a quicker recovery and to improve the patient's cosmetics continue. The aim of this study is to report the results of the first 100 cases of single port laparoscopic cholecystectomy performed in a secondary care hospital. MATERIAL AND METHODS: Prospective, observational and unicentric study including 100 patients between January 2010 and April 2012. INCLUSION CRITERIA: symptomatic cholelythiasis patients over 16-years of age on whom a single port laparoscopic cholecystectomy was performed. EXCLUSION CRITERIA: history of acute cholecystitis, pancreatitis or suspected choledocholithiasis, Endoscopic retrograde cholangiopancreatography, BMI>35 and previous laparotomies. We studied epidemiological, surgical and safety variables. RESULTS: The mean patient age was 39,89 ± 11,5 years. The mean time of the surgical procedure was 67,94 ± 25,5 min. There were 2 cases of postoperative complications. A non-infected seroma and a biliar leak. In 2 cases the use of an accessory trocar was needed. The mean hospital stay was 1,13 ± 0,8 days. A total of 35% patients were included in the major ambulatory surgery programme.The overall patient satisfaction survey rating showed a high level of cosmetic satisfaction in 100% of patients. CONCLUSIONS: Single port laparoscopic cholecystectomy is a good technique when performed in selected cases by expert surgeons. It is feasible to include the single port laparoscopic cholecystectomy in a major ambulatory surgery programme. We have not had serious complications. There is a high cosmetic satisfaction index with this technique.

Abordaje transumbilical en pacientes pediátricos con diagnóstico de apendicitis aguda. una serie de 424 pacientes / Transumbilical approach in pediatric patients with suspected acute appendicitis. a series of 424 patients

Antecedentes: El tratamiento de la apendicitis aguda implica su extirpación; es frecuente la solicitud de cicatrices postquirúrgicas del mejor tamaño posible. Una de las estrategias disponibles es el abordaje transumbilical. Objetivo: Describir las características clínicas y los desenlaces operatorios de los pacientes pediátricos en quienes se realiza apendicectomía vía transumbilical. Metodología: Estudio prospectivo de 424 pacientes sucesivos en cuanto a los desenlaces operatorios a corto plazo. Resultados: El tiempo promedio de intervención quirúrgica fue de 22 minutos; 95.8% de los pacientes presentó evolución satisfactoria del postquirúrgico; 1.4% de los pacientes se reintervino para drenar un absceso intracavitario residual y 0.2% presentó infección de sitio operatorio sin más complicaciones. Conclusión: El abordaje transumbilical de la apendicitis es una alternativa mínimamente invasiva para todos los estados de apendicitis aguda e implica disminución del tiempo de realización, menor estancia del posquirúrgico, menor incidencia de complicaciones y mayor conformidad con los resultados estéticos.

Background: As the treatment of acute appendicitisinvolves excision it is common for the patient to ask for thesmallest possible postsurgical scar. One available strategy is the transumbilical approach. Objective: To describe theclinical characteristics and surgical outcomes of pediatricpatients scheduled for transumbilical appendectomies. Methodology: A prospective study of 424 consecutivepatients in terms of short-term operative outcomes. Results:The average surgery time was 22 minutes. 95.8% of patientshad satisfactory postoperative evolution. 1.4% underwentsurgery to drain a residual intracavitary abscess, and 0.2% had surgical site infection without other complications. Conclusion: The transumbilical approach for the treatmentof appendicitis is a minimally invasive alternative for all acuteappendicitis states and result in decreased surgical time,shorter postoperative stays, lower incidence ofcomplications, and greater conformity with the aesthetic results.
