Enucleation of a leiomyoma of the mid-esophagus through a right thoracoscopy with the patient in prone position.

BACKGROUND: Leiomyoma is the most common benign esophageal neoplasm. Different open and minimally invasive approaches have been described. We describe a right thoracoscopic enucleation with the patient in the prone position. METHOD: A 49-year-old woman consulted us about solid-diet dysphagia without other symptoms. Preoperative work-up showed the presence of 50 x 28-mm leiomyoma of the middle esophagus, without satellite lymph nodes. The patient underwent general anesthesia with a double-lumen endotracheal tube, and subsequently was placed in the prone position. A 30 degrees scope was introduced in the right 7th intercostal space on the posterior axillary line. Perioperative gastroscopy permitted localization of the lesion, which appeared to be situated at the level of the azygos vein. Two 5-mm trocars were inserted in the right 5th and 9th intercostal spaces on one line with the first one. The azygos vein was ligated. The muscular layer of the mid-esophagus was opened by coagulating hook. Due to a 2-mm trocarless Cadière's forceps (Microfrance, France), introduced into the right 7th intercostal space, the operative field was well exposed and the lesion was enucleated without mucosal perforation. The muscular layer was closed by interrupted silk 2/0 stitches. A drain was left in the chest cavity. RESULTS: Total operative time was 85 min and blood loss was less than 20 ml. The gastrograffin swallow on postoperative day 2 showed good clearance of the esophagus and absence of leak, hence the patient was allowed a liquid diet. The patient was discharged on postoperative day 3. Benign pathology was confirmed. CONCLUSION: Thoracoscopy in the prone position permits the surgeon to reach the esophagus under excellent working conditions, despite an only partially deflated lung. Gravity displaces blood loss eventually, which allows good visualization, and the surgeon can operate in an ergonomic position. This approach allows for fewer trocars which favorably influences the patient's comfort and reduces the length of hospital stay.

Barbiturate coma for intracranial hypertension: clinical observations.

PURPOSE: To determine the neurologic outcome of patients with intracranial hypertension treated with barbiturate-induced coma. MATERIALS AND METHODS: The records of 49 patients who were admitted to a 31-bed medicosurgical intensive care unit over a 5-year period in whom a barbiturate coma was induced to control intracranial hypertension were analyzed retrospectively. Analysis included assessment of the response to barbiturate coma and evaluation of the long-term neurologic outcome according to the Glasgow Outcome Scale (GOS). RESULTS: Intracranial hypertension was caused by head trauma in 28 patients and subarachnoid hemorrhage in 21 patients. Eight of the head trauma patients and 5 of the patients with subarachnoid hemorrhage survived their hospital stay. The survivors were younger than the nonsurvivors, and had a good neurologic status after 1 year (except for 2 patients who died 1 and 3 months after discharge, respectively). There was no significant difference in the Glasgow Coma Score (GCS) on admission between the survivors and the nonsurvivors. The long-term outcome at 1 year was markedly better in the patients who had experienced a subarachnoid hemorrhage than in the trauma patients.

Ultrasound-guided block of the brachial plexus at the humeral canal.

PURPOSE: Conduction block of the brachial plexus block at the humeral canal, as described by Dupre, has certain clinical indications. The aim of this preliminary study was to assess the feasibility of this technique under ultrasound guidance. METHODS: After ultrasound evaluation of the brachial plexus at the humeral canal in 61 adult volunteers, we performed ultrasound-guided blocks in another 20 adult patients. A linear 38 mm probe, 13-6 MHz, and a 50-mm insulated block needle were used to guide injection of lidocaine 1.5% with epinephrine. RESULTS: Ulnar and median nerves are superficial and located at similar depths. Ultrasound imaging showed the musculocutaneous nerve to be located dorsally. The radial nerve is dorsal to the plane of the musculocutaneous nerve. Relative to the brachial artery, the median nerve is situated between 12 and 1 o'clock in 66% of the cases. Relative to the basilic vein, the ulnar nerve is situated at 3 o'clock in 46% of the cases. The evaluated block sequence was radial, ulnar, musculocutaneous and median nerve; two points of puncture were mandatory, and 6.85 +/- 0.37 min were required to perform the blocks. Sensory onset times were similar for the four nerves. Injectate volume was lower for the musculocutaneous nerve compared to other nerves (P < 0.05). All 20 patients experienced complete sensory and motor blocks. CONCLUSION: We describe an approach to, and the feasibility of ultrasound-guided block of the brachial plexus at the humeral canal. Further study will be required to establish the effectiveness and the safety of this technique.

The anesthetic management of a case of tracheal necrosis.

A 63-yr-old female patient developed a tracheal necrosis after esophageal resection with gastric interposition. We report the anesthetic management of this patient undergoing tracheal repair focusing on an original airway management and ventilation strategy.
