AbstractSurgical intervention for umbilical diseases in calves, when indicated, is a complementary and indispensable therapeutic resource for the treatment of umbilical conditions and is commonly performed using celiotomy. However, laparoscopy has demonstrated feasibility in many diagnostic and therapeutic procedures. The aim of this study was to assess the feasibility of the techniques and the surgical time of laparoscopy and celiotomy used in intra-abdominal resection of the umbilical vein and urachus of bovine fetuses (cadavers). Resection of the umbilical vein and urachus using laparoscopy and celiotomy was performed in 26 anatomical specimens (bovine fetuses obtained from an official slaughterhouse). Resection of umbilical structures was feasible with both techniques, but shorter surgical time and minimal tissue damage were achieved using laparoscopy. Laparoscopy requires specialized training and appropriate instruments and is an important tool for diagnostic and therapeutic exploration of the umbilical structures, liver, bladder, and associated/adjacent structures.

Introduction: Alveolar echinococcosis (AE) is a zoonosis caused by Echinococcus multilocularis. AE is primarily localised in the liver. Echinococcus multilocularis imitates tumour-like behaviour. It can metastasise through blood or lymphatic system to distant organs. Echinococcosis often remains asymptomatic due to its long incubation period and indistinct symptoms. Clinical symptoms are determined by the parasite’s location. Diagnosis of echinococcosis is based on medical history, clinical symptoms, laboratory tests, serology results, imaging methods and final histology findings. Surgical removal of the cyst with a safety margin, followed by chemotherapy is the therapeutic method of choice. Case report: We present a case report of alveolar echinococcosis in a thirty-year-old female patient in whom we surgically removed multiple liver foci of alveolar echinococcosis. The disease recurred after two years and required another surgical intervention. Conclusions: Alveolar echinococcosis is a disease with a high potential for a complete cure provided that it is diagnosed early and that the recommended therapeutic procedures are strictly adhered to.

Paranasal sinus mucocele is a slowly growing benign cystic lesion. It usually involves the frontal and ethmoid sinuses and can extend to adjacent structures, especially to the orbit, skull base and brain parenchyma. Prompt surgical intervention is needed when symptoms occur. Complete resection of mucocele is approached via endoscopic sinus surgery, while marsupialization is also widely considered. Recently, we encountered a case of spontaneous brain herniation and cerebrospinal fluid leakage during endoscopic marsupialization of ethmoid sinus mucocele. Herein, we report the case with a review of the literature.

Epignathus is a rare congenital orofacial teratoma that arises from the sphenoid region of the palate or the pharynx. It occurs in approximately 1:35,000 to 1:200,000 live births representing 2% to 9% of all teratomas. We present the case of a newborn of 39.4 weeks of gestation with a tumor that occupied the entire oral cavity. The patient was delivered by cesarean section. Oral resection was managed by pediatric surgery. Plastic surgery used virtual 3-dimensional models to establish the extension, and depth of the tumor. Bloc resection and reconstruction of the epignathus were performed. The mass was diagnosed as a mature teratoma associated with cleft lip and palate, nasoethmoidal meningocele that conditions hypertelorism, and a pseudomacrostoma. Tridimensional technology was applied to plan the surgical intervention. It contributed to a better understanding of the relationships between the tumor and the adjacent structures. This optimized the surgical approach and outcome.

Background and objectivesThe intercostobrachial nerve (ICBN) has significant anatomical variation. Localization of the ICBN requires an operator’s skill. This cadaveric study aims to describe two simple ultrasound-guided plane blocks of the ICBN when it emerges at the chest wall (proximal approach) and passes through the axillary fossa (distal approach).MethodsThe anatomical relation of the ICBN and adjacent structures was investigated in six fresh cadavers. Thereafter, we described two potential techniques of the ICBN block. The proximal approach was an injection medial to the medial border of the serratus anterior muscle at the inferior border of the second rib. The distal approach was an injection on the surface of the latissimus dorsi muscle at 3–4 cm caudal to the axillary artery. The ultrasound-guided proximal and distal ICBN blocks were performed in seven hemithoraxes and axillary fossae. We recorded dye staining on the ICBN, its branches and clinically correlated structures.ResultsAll ICBNs originated from the second intercostal nerve and 34.6% received a contribution from the first or third intercostal nerve. All ICBNs gave off axillary branches in the axillary fossa and ran towards the posteromedial aspect of the arm. Following the proximal ICBN block, dye stained on 90% of all ICBN’s origins. After the distal ICBN block, all terminal branches and 43% of the axillary branches of the ICBN were stained.ConclusionsThe proximal and distal ICBN blocks, using easily recognized sonoanatomical landmarks, provided consistent dye spread to the ICBN. We encourage further validation of these two techniques in clinical studies.

AbstractSphenoid sinus mucocoeles can stimulate a variety of pathological conditions and patients can present to a range of specialists. Because of the relative rarity of sphenoid sinus mucocoeles, diagnosis is often delayed and these lesions can progressively expand and cause direct mechanical compression on adjacent structures. We present three cases which presented with an abducens nerve palsy. Early surgical intervention is advocated and these patient's symptoms resolved following surgery. Although several conditions can present with an abducens nerve palsy, it is important to consider a sphenoid sinus mucocoele in the differential diagnosis.

Tissue damage as sequelae after spontaneous intracerebral hemorrhage in eight consecutive patients was investigated with computed tomography performed 3 days, 2 weeks and 6 months after the stroke. The presence of contrast enhancement after 2 weeks, hypodense areas after 6 months, and atrophy of adjacent structures were considered to be markers of irreversible tissue damage. Except for a narrow zone in the periphery of the hematoma (ring blush) contrast enhancement was not observed, neither in the hematoma nor in areas where resolution had taken place. After 6 months the site of the hematomas was not identifiable in 3 patients, and 4 patients had small ‘lacunar’ hypodense lesions. Only one patient had a more extensive hypodense area 6 months after the hemorrhage. The most prominent sequelae after intracerebral hematoma were atrophy of adjacent structures (i.e. atrophy of basal ganglia, thalamus and ventricular enlargement) which were seen in all patients even though irreversible de loco damage in the hematoma area was sparse or absent.

Water Hammer Effect

Vertebrobasilar dolichoectasia is a clinical entity associated rarely with obstructive hydrocephalus. We present a 48-year-old male with a profound dilatation of the ventricular system due to a dolichoectatic basilar artery, as appeared in imaging studies. The patient suffered from longstanding hydrocephalus and presenile dementia. The underlying mechanism for obstructive hydrocephalus due to vertebrobasilar dolichoectasia is considered to be both a <em>water-hammer effect</em> and a direct compression of adjacent structures. We suggest prompt surgical intervention upon diagnosis as a first choice treatment in order to avoid further complications.

The typical blood platelet fluctuation repeatedly observed in man following surgical interventions and characterized by thrombocytopenia during the first 2 days and thrombocytosis after 5 to 8 days, has been reproduced in rats subjected to certain procedures, provided these were accompanied by severe tissue damage. An E. coli endotoxin injected intravenously or intraperitoneally induced a similar fluctuation and markedly potentiated the effects of the tissue damage on the blood platelets. This variation in the platelet count could be a stress effect, since it was completely reproduced by forced immobilization in the absence of any gross tissue damage. Ether anesthesia seems to reduce the magnitude of this stress-induced platelet fluctuation.

Purpose: To evaluate the surgical intervention and its effect on congenital dacryocystocele. Methods: A total of 531 children with congenital dacryocystocele admitted to the Department of Ophthalmology of Beijing Children’s Hospital, Shanghai Aier Eye Hospital, Nanjing Aier Eye Hospital, and the First Affiliated Hospital of Jinzhou Medical University between January 2007 and January 2017 were retrospectively analyzed. Results: A total of 531 patients were followed up for 3–24 months, with an average of 13.3 months. No serious intraoperative complications (such as bleeding and tissue damage) and postoperative complications (bleeding, infection, and hole atresia) were found. We classified the outcomes into three categories based on the signs (overflowing tears and empyema) and objective routine follow-up by endoscopy. Cure indicated that mass, overflow of tears, and breathing difficulties disappeared, and 81.5% cases (433/531) were postoperatively cured. Improvement indicated disappearance of mass, overflow empyema, and the presence of residual tears (due to trocar and tears puncture), and 18.5% cases (98/531) were postoperatively improved. Unhealed indicated overflowing pus and tears, and 0% cases did not heal after surgery. Conclusions: Nasal endoscopic surgery is relatively safe, with high success rate for treatment of congenital dacryocystocele. Systematic training is required to promote the application of nasal endoscopy, so that more ophthalmologists can learn this technique.
