Caustic ingestion may cause devastating injuries of the upper gastrointestinal tract and the respiratory system. We report here the successful treatment of a 37-year-old patient who ingested hydrochloric acid (100 mL; 24%) in suicidal intention. An oesophagogastroduodenoscopy revealed extensive necrosis of the gastric mucosa. A diagnostic laparoscopy was performed and confirmed the suspected transmural necrosis which resulted in a discontinuous laparoscopic gastrectomy. During the next days, the oesophageal stump was monitored through frequent oesophagoscopies and showed a good recovery. Thus, it was possible to restore continuity as early as by the sixth postoperative day performing a roux-en-y oesophagojejunostomy using the da Vinci Xi surgical robot. The patient underwent all procedures without any surgical complications and was discharged almost 1 month after initial presentation in good general condition.

Bone is a frequent site of metastases in advanced cancers including lung, breast, prostate, kidney, or myeloma. Lesions are commonly located on the spine. Neoplastic invasion of the vertebral body can result in painful vertebral fractures, leading to disability and substantial morbidity. Percutaneous vertebroplasty is a minimally invasive surgical procedure used to treat spinal fractures due to osteolytic tumors. It could result in pain reduction or resolution in 80–90% of patients with fractures, and it improves stability. Although considered safe, vertebroplasty has been associated over the years with life-threatening complications. We have reported the case of a 55-year-old patient with lung adenocarcinoma, who underwent vertebroplasty for a pathological neoplastic fracture of L2. The procedure was complicated by a leak of cement into the systemic venous circulation, characterized by an 11-cm filament in the right heart chambers and multiple pulmonary emboli. To our knowledge, only one similar case was previously reported, involving an intracardiac cement filament longer than 10 cm. The data are scant, hence the importance of collecting and reporting possible complications about what is perceived as a rather safe procedure. The case highlights the need for a robust postprocedure imaging plan to detect complications, which can impact patients’ morbidity and survival.

AbstractDeep brain stimulation (DBS) is becoming an increasingly popular minimally invasive surgical procedure for various movement disorders, especially Parkinson’s disease. Different nuclei have been identified depending on patients’ symptoms, but the success or failure of the procedure depends on various other factors such as proper patient selection and risk-benefit analysis. While various techniques of anaesthesia including monitored anaesthesia care, conscious sedation and general anaesthesia are being used routinely, no clear-cut evidence exists as to the best technique for this procedure. This review article discusses the surgical procedure of DBS, devices currently available, perioperative anaesthetic concerns and techniques, effect of anaesthetic drugs on microelectrode recordings and macro-stimulation and associated complications.

The issue of brain magnetic resonance image exploration together with classification receives a significant awareness in recent years. Indeed, various computer-aided-diagnosis solutions were suggested to support radiologist in decision-making. In this circumstance, adequate image classification is extremely required as it is the most common critical brain tumors which often develop from subdural hematoma cells, which might be common type in adults. In healthcare milieu, brain MRIs are intended for identification of tumor. In this regard, various computerized diagnosis systems were suggested to help medical professionals in clinical decision-making. As per recent problems, Neuroendoscopy is the gold standard intended for discovering brain tumors; nevertheless, typical Neuroendoscopy can certainly overlook ripped growths. Neuroendoscopy is a minimally-invasive surgical procedure in which the neurosurgeon removes the tumor through small holes in the skull or through the mouth or nose. Neuroendoscopy enables neurosurgeons to access areas of the brain that cannot be reached with traditional surgery to remove the tumor without cutting or harming other parts of the skull. We focused on finding out whether or not visual images of tumor ripped lesions ended up being much better by auto fluorescence image resolution as well as narrow-band image resolution graphic evaluation jointly with the latest neuroendoscopy technique. Also, within the last several years, pathology labs began to proceed in the direction of an entirely digital workflow, using the electronic slides currently being the key element of this technique. Besides lots of benefits regarding storage as well as exploring capabilities with the image information, among the benefits of electronic slides is that they can help the application of image analysis approaches which seek to develop quantitative attributes to assist pathologists in their work. However, systems also have some difficulties in execution and handling. Hence, such conventional method needs automation. We developed and employed to look for the targeted importance along with uncovering the best-focused graphic position by way of aliasing search method incorporated with new Neuroendoscopy Adapter Module (NAM) technique.

Anterior basal (S8) segmentectomy is one of the most challenging procedures among the uncommon pulmonary segmentectomies because the surgeon has to identify dominant pulmonary vein branches located deep in the lung parenchyma. Moreover, with the uniportal thoracoscopic approach, the angulation of inserted surgical instruments via a single small incision is extremely limited, which causes technical difficulties. However, adoption of a suitable procedure such as unidirectional dissection enables us to perform this type of minimally invasive surgical procedure. We describe the successful results of a patient undergoing uniportal thoracoscopic S8 segmentectomy of the right lower lobe and explain the nuances of performing it.

Tissue damage that is associated with the loss of cell membrane integrity should alter the bulk electrical properties of the tissue. This study shows that electrical impedance tomography (EIT) should be able to detect and image necrotic tissue inside the body due to the permeabilization of the membrane to ions. Cryosurgery, a minimally invasive surgical procedure that uses freezing to destroy undesirable tissue, was used to investigate the hypothesis. Experimental results with liver tissue demonstrate that cell damage during freezing results in substantial changes in tissue electrical properties. Two-dimensional EIT simulations of liver cryosurgery, which employ the experimental data, demonstrate the feasibility of this application.

Malignant tumors of the central nervous system are the third leading cause of cancer-related deaths in adolescents and adults between the ages of 15 and 34; in children, brain tumors are the leading cause of cancer death. Convection-enhanced delivery (CED) has emerged as a promising method for the transport of high concentrations of chemotherapeutic macromolecules to brain tumors. CED is a minimally-invasive surgical procedure wherein a stereotactically-guided small-caliber catheter is inserted into the brain parenchyma, to a tumor site, for low flowrate infusion of chemotherapy [1]. This direct-delivery method bypasses obstacles to systemic chemotherapy caused by the selective impermeability of the blood-brain barrier. Although preliminary studies were favorable, CED recently failed Phase III FDA trials because clinical goals for tumor regression were not met [2]. This was primarily attributed to insufficient diffuse delivery of the drug throughout tumor masses and their surrounding margins.

Pancreatic islet transplantation into type 1 diabetic patients is currently being performed by intraportal infusion. This method, albeit reproducible, has some disadvantages including potential development of portal hypertension, hemorrhage, and an inability to retrieve or detect the transplanted tissue. Other transplant sites have been examined in animal models including the omentum, peritoneal cavity, and the spleen. A transplant site that has not been successful in supporting functional islet tissue transplantation in humans is the subcutaneous space due primarily to the lack of a well-defined vascular bed. This site has many favorable characteristics such as ease of access for transplantation and potential for removal of the transplanted tissue with a minimally invasive surgical procedure. This report addresses the evaluation of a subcutaneously placed device for the support of rat syngeneic islet transplantation in a streptozocin-induced diabetic model. The data generated support the use of this device for islet engraftment. In addition, beta cell function in this device compared favorably with the function of islets transplanted to the renal subcapsular space as well as islets within the native pancreas.

Arthroscopic surgery is a minimally invasive surgical procedure that is widely used on joints. However, conventional endoscope-based arthroscopic surgery does not provide stereoscopic information to the surgeon. To overcome this limitation, we have developed a modified endoscopic system that uses an optical fiber (1 mm diameter) for three-dimensional imaging of knee joints. Our endoscopic system is able to operate underwater in real time. It consists of a laser beam that is projected on the surface of the object to be imaged via an optical fiber. A prism is used to decrease the length and diameter of baseline and endoscope tube, respectively. The small diameter (8 mm) of our endoscope makes it extremely convenient for application in arthroscopic surgery. The feasibility of the proposed system has been demonstrated via experiments on synthetic knee joints.
