Laparoscopic Management of Abdominal Echinococcosis: A Technical Report on Surgical Techniques and Outcomes.

This technical report explores the efficacy and methodology of laparoscopic surgery for treating abdominal echinococcosis, a parasitic infection caused by Echinococcus granulosus. We highlight the zoonotic nature of the disease, which predominantly affects the liver and occasionally other organs, noting the challenge of its asymptomatic progression that complicates timely diagnosis and intervention. We detail our surgical technique using a standard laparoscopy kit to address abdominal hydatid cysts, emphasizing the critical importance of preventing cyst rupture and spillage to avoid recurrence and anaphylactic shock. We discuss considerations for opting for laparoscopy over open surgery, such as reduced postoperative morbidity, faster patient recovery, and lower costs, while also acknowledging limitations like restricted instrument movement and the absence of haptic feedback. We advocate hypertonic saline as the preferred scolicidal agent and strategies to minimize spillage and manage the residual cavity. In conclusion, we assert that laparoscopy offers a viable and effective treatment option for abdominal echinococcosis, emphasizing that optimizing outcomes for this benign condition hinges on careful patient selection and a conservative surgical approach.

Primary Retroperitoneal Hydatid Cyst: A Diagnostic and Treatment Conundrum.

Hydatid cysts are caused by accidental egg ingestion of the Echinococcus granulosus parasite. A 24-year-old female was admitted to our hospital for chronic left lumbar pain. Computed tomography (CT) and abdominal ultrasonography identified an 8/12 cm retroperitoneal cyst. The CT results coupled with enzyme-linked immunosorbent assay tests (positive IgG for Echinococcus granulosus) confirmed that the tumor was a hydatid cyst. Treatment consisted of preoperative chemotherapy with albendazole, intraoperative parasite inactivation, laparoscopic partial cystectomy, and drainage. The drain was removed after three days. Chemotherapy was maintained for two years after surgery. No relapse was observed at the six-month reevaluation. In this article, the diagnostic and therapeutic options and resources are discussed and compared with the published literature.

Decoding Hepatic Portal Venous Gas: A Case Report.

Hepatic portal venous gas (HPVG) is an infrequent and life-threatening condition with high morbidity and mortality rates, which consists of the presence of gas in the portal vein and its branches. Improvements in imaging technologies have led to the diagnosis of HPVG in less severe circumstances, which, in turn, has only determined a small amelioration of the prognosis. We present a rare case of HPVG subsequent to paralytic ileus in a patient who attained long-term survival after the surgical treatment was performed. HPVG is considered to be associated with sepsis, parietal/mucosal damage, inflammation of the intraperitoneal organs, and meteorism, which may be found in a variety of pathologies. The severity of this pathology depends on the pre-existing conditions of the patients but also on how quickly a treatment plan is established and applied. As a correct and timely diagnosis is crucial for the increase of the survival rate in HPVG, greater attention shall be paid to the clinical manifestations and the differential diagnosis.

Axillary Lymphadenectomy: Safe Dissection Through a Correct Technique.

The primary treatment of breast cancer in sentinel-positive ganglia includes axillary lymphatic nodal dissection. The LAD (lymphatic axillary dissection) has decreased in overall numbers but due to the increasing incidence of breast cancer, it is practised on a daily basis, even though there is a myriad of complications such as numbness of the upper limb and chest wall, movement restriction of the upper limb, and chronic pain which appear due to trauma to the nerves which pass through the axilla. However, the utility in the overall survival or DFS (disease-free survival) of the patient is unquestionable.  In our study, through the dissection of cadavers, we exposed the vital structures and the anatomical relations of this region. We aimed to offer a map or technique for the surgeon to follow to decrease the overall morbidity of this procedure.

Prostatic Artery Origin Variability: Five Steps to Improve Identification during Percutaneous Embolization.

Background and Objectives: The purpose of the current paper is to present our study on the variability in the prostatic artery origin, discuss the less frequent origins, and present the challenges of the prostatic artery embolization (PAE) procedure, thus aiding young interventional radiologists. Materials and Methods: We studied the origins of the prostatic artery on digital subtraction angiography (DSA) examinations from PAE procedures on 35 male pelvises (70 hemi-pelvises). Results: Our study has demonstrated that the most frequent origin of the prostatic artery (PA) is the internal pudendal artery (IPA), 37.1%, followed by the anterior gluteal trunk, 27.1%, and the superior vesical artery (SVA), 21.4%. Less frequent origins are the obturator artery (OBT), 11.4%, and the inferior gluteal artery (IGA), 2.8%. Conclusions: Compared to other studies, we notice some differences in the statistical results, but the most frequent origins remain the same. What is more important for young interventional radiologists is to be aware of all the possible origins of the PA in order to be able to offer a proper treatment to their patients. The important aspect that will ensure the success of the procedure without post-procedural complications is represented by the successful embolization of the targeted prostatic parenchyma.

The Pelvic and Sacral Splanchnic Nerves - Identification by Dissection, Trajectory.

The modern principles in pelvic surgery imply the preservation of the nervous structures that are involved in the physiological functioning of the pelvic and genital organs. The main pelvic nervous element is represented by the inferior hypogastric plexus. This plexus receives sympathetic afferent fibres from the hypogastric nerve, parasympathetic afferent fibres from the pelvic splanchnic nerves and also sympathetic afferent fibres coming from the sympathetic sacral chain via the sacral splanchnic nerves. We aimed to demonstrate the anatomy of these structures through dissection and we exposed the origins, pathway and manner of distribution of the splanchnic nerves of the pelvis. We managed to clarify the main anatomical relations of these nerves, among which we highlighted the relation to the branches of the internal iliac artery. The parasympathetic fibres reach the pelvis by running through the anterior rami of the spinal nerves, which are the origin of the sacral plexus. We managed to exhibit the way in which the parasympathetic fibres emerge from the sacral nerves and form the pelvic splanchnic nerves. Pelvic surgery nowadays is focused on nerve-sparing, which essentially means the conservation of the integrity of splanchnic nerves, hypogastric nerves and inferior hypogastric plexuses in order to maintain the normal functioning of the anatomical sphincters and genital organs. In this respect, it is crucial for the surgeon who performs pelvic procedures to be more than well-acquainted to the anatomy of the pelvic splanchnic nerves, which are considered to be the erectile nerves, and to that of the sacral splanchnic nerves.

The pterygopalatine ganglion, palatine nerves and vessels: dissection and pathway / El ganglio pterigopalatino, nervios palatinos y vasos: disección y trayecto

SUMMARY: Background and Objectives: The palatine nerves and vessels cross the pterygopalatine fossa, the palatine canals, the palatine foramina and the submucosal space, at the level of the hard palate and the palatine recess of the maxillary sinus. Their trajectory is long, complicated and difficult to highlight on a single dissection piece. In the literature that we studied, we did not find clear images that fully highlight the real configuration of the pterygopalatine ganglion and nerves and of the palatine vessels. Our aim was to provide a clear and representative dissection of the pterygopalatine ganglion and of the palatine neurovascular bundle throughout its pathway in a simple, coherent and useful presentation for the practitioners interested in the regional pathology. We resected the posterior and inferomedial osseous walls of the maxillary sinus and highlighted the neurovascular structures in the pterygopalatine fossa and the wall of the maxillary sinus. We photographed the dissection fields and detailed the important relations. The images that we obtained are clear, simple and easy to interpret and use. We successfully highlighted the aspect and the main relations of the pterygopalatine ganglion and the pathway and distribution of the palatine nerves and vessels, from their origin to the terminal plexuses. There is a broad spectrum of clinical procedures or situations that require a proper knowledge and understanding of the anatomical pathway and relations of the palatine neurovascular elements. This includes the various types of regional anesthesia, tumor resection surgery, flaps of the palatine mucosa, the LeFort osteotomy etc. Demonstration of the pterygopalatine ganglion and its relations is useful in endoscopic interventions at the level of the pterygopalatine fossa.

RESUMEN: Los nervios y vasos palatinos atraviesan la fosa pterigopalatina, además de los canales palatinos, los forámenes palatinos y el espacio submucoso a nivel del paladar duro y el receso palatino del seno maxilar. Su trayectoria es larga, complicada y difícil de destacar en una sola pieza de disección. En la literatura que estudiamos, no encontramos imágenes claras que resalten completamente la configuración real del ganglio y los nervios pterigopalatinos y de los vasos palatinos. Nuestro objetivo fue proporcionar una disección clara y representativa del ganglio pterigopalatino y del haz neurovascular palatino a lo largo de su trayecto en una presentación simple, coherente y útil para los médicos interesados en la patología regional. Resecamos las paredes óseas posterior e inferomedial del seno maxilar y resaltamos las estructuras neurovasculares en la fosa pterigopalatina y la pared del seno maxilar. Fotografiamos los campos de disección y detallamos las relaciones importantes. Las imágenes que obtuvimos son claras, sencillas y de fácil interpretación. Resaltamos con éxito el aspecto y las principales relaciones del ganglio pterigopalatino y el trayecto y distribución de los nervios y vasos palatinos, desde su origen hasta los plexos terminales. En conclusion, existe un amplio espectro de procedimientos o situaciones clínicas que requieren un adecuado conocimiento y comprensión del trayecto anatómico y las relaciones de los elementos neurovasculares palatinos. Esto incluye los distintos tipos de anestesia regional, cirugía de resección tumoral, colgajos de mucosa palatina, osteotomía de LeFort, etc. La demostración del ganglio pterigopalatino y sus relaciones es útil en intervenciones endoscópicas a nivel de la fosa pterigopalatina.

Morphological study of cephalothoracopagus deradelphus type conjoined twins. A case report.

Cephalopagus is a rare variety of conjoined twins. They are fused with their heads, thoracic and upper abdominal cavities. The exact mechanism for development of conjoined twins cannot be clearly explained. It appears that there is an alteration in the normal developmental process of monozygotic twins, which fail to separate from each other. We present the morphology of a cephalothoracopagus, revealed through anatomical dissection, emphasizing the arrangement of the viscera in the thoracic and abdominal cavities. They are fused with their heads, thoracic and upper abdominal cavities. The lower abdomen and pelvic cavities are free. Each twin has two upper and lower limbs, normally shaped. Each twin has a heart and two lungs. There is a single pharynx, esophagus and stomach, but normal lower abdominal systems. The genital and urinary systems are apparently normal. Due to the fusion of the heads and abnormal arrangement of the superior central nervous system, surgery is not attempted in these cases, the prognosis being very poor.

Morphological and ultrasonographic study of fetuses with cervical hygroma. A cases series.

Cystic cervical hygroma or cervical cystic lymphangioma is a congenital benign disease of the lymphatic system that is characterized by the accumulation of lymph in the jugular lymphatic sacs of the nuchal region. The factor that causes this pathology is not clarified yet but the physiopathological mechanism seems to be multifactorial. The incidence and prevalence of cervical hygroma are increased in patients with Turner syndrome, Down syndrome, Klinefelter syndrome, Edwards syndrome, Patau syndrome, Noonan syndrome, pterygium syndrome, Cantrell pentalogy, Fryns syndrome, Apert syndrome, Pena-Shokeir syndrome and achondroplasia. The gold standard method in establishing the antenatal diagnosis is ultrasonography, a non-invasive and low-cost procedure. We report four cases of fetuses who were diagnosed antepartum with cervical hygroma in the Department of Obstetrics and Gynecology of the University Emergency Hospital in Bucharest, Romania. Two products of conception were send to the Department of Anatomy of the "Carol Davila" University of Medicine and Pharmacy, Bucharest, for an extensive morphological analysis. Cervical cystic hygroma is a congenital condition of variable expression in terms of both morphology and chronology. A complete ultrasound examination, performed by an experimented specialist in maternal-fetal medicine is essential in establishing the diagnosis of cervical hygroma. Screening for aneuploidies, between the 11th and 14th weeks of pregnancy is also mandatory due to the frequent association between cervical hygroma and congenital anomalies.

Natural orifice translumenal endoscopic surgery (NOTES) second-look peritoneoscopy for staging of limited peritoneal carcinomatosis.

BACKGROUND: Over the past decades, staging laparoscopy evolved as a useful tool in multimodality treatment of patients with abdominal malignancies, especially for detection of incurable peritoneal and liver metastasis. Natural orifice translumenal endoscopic surgery (NOTES) is a new, evolving technique which represents the next logical progression in minimally invasive surgery and has theoretical advantages in comparison with standard laparoscopic surgery. A review of the current literature revealed a continuous increasing number of fundamental and clinical studies addressing NOTES approach in multimodal management of oncologic patients. Technical possibility to use this new minimally invasive approach for oncological resection of abdominal malignancies was proved by some investigators. HYPOTHESIS: NOTES can be used as an alternative method for staging patients with limited peritoneal carcinomatosis and may have better results compared to current imaging techniques for small diameter metastatic disease. CONCLUSIONS: With the continuous development of the NOTES techniques and technology, the second-look peritoneoscopy by NOTES may become an alternative method for staging in patients with peritoneal carcinomatosis. Nevertheless, NOTES is at a very early stage of its development, and its implementation in oncologic surgery should be made very caution, and only after careful evaluation.

Complex Ebstein's malformation: defining preoperative cardiac anatomy and function.

INTRODUCTION: Ebstein's malformation is a congenital malformation of the tricuspid valve and right ventricle, with a highly variable morphology, and clinical presentation, accounting for less than 1% of all congenital heart diseases, and about 40% of congenital malformations of the tricuspid valve. METHOD: Systematic review of English language literature regarding the morphogenesis and progress of imaging techniques, especially echocardiography and cardiac magnetic resonance imaging, in the preoperative planning of Ebstein's malformation, using the MEDLINE database with the PubMed Entre interface. RESULTS: Technological developments of the recent years, with 3D echocardiographic and cardiac magnetic resonance imaging evolution, have resulted in better understanding of the malformed tricuspid valve and right ventricle in vivo anatomy. Through a better understanding of Ebstein's malformation, there is a continuous trend of surgical techniques favoring tricuspid valve sparing procedures, with a constant decrease in early and late postoperative mortality. CONCLUSIONS: Although imaging methods to investigate Ebstein's malformation have continuously evolved, standardization of assessment protocols by 3D echocardiographic imaging, speckle tracking imaging, and cardiac magnetic resonance imaging is required.
