Air Leakage (air + leakage)
Selected AbstractsTracheal perforation secondary to suture irritation in a dog following a ventral slot procedureJOURNAL OF SMALL ANIMAL PRACTICE, Issue 7 2003D. N. Clements An eight-year-old springer spaniel was presented with acute-onset subcutaneous emphysema of five days' duration. The dog had undergone ventral slot decompression of the C5-C6 intervertebral disc space eight weeks before presentation. Cervical tracheoscopy demonstrated perforation of the dorsal tracheal membrane of the distal cervical trachea. Perforation of the dorsal tracheal membrane secondary to suture knot irritation was confirmed by exploratory surgery. Repair of the perforation was performed by plication of the dorsal tracheal membrane. The dog was represented nine days after the initial surgery with acute recurrence of subcutaneous emphysema. Air leakage at the plicated dorsal tracheal membrane was observed at exploratory surgery, and a bipedicle sternothyroideus muscle flap was used to support the plicated membrane. Recovery was uneventful and 10 months postoperatively there had been no recurrence of clinical signs.

Kurkcuoglu Summary To review the results of different surgical treatment in hydatid disease of the lung in paediatric patients. A total of 102 children with pulmonary hydatid cysts were treated at the our clinic in the period from 1990 to 2001. There were 59 boys and 43 girls and their age ranged from 4 to 16 years (mean 10.2). Chest radiography, computed tomography and abdominal ultrasonography were the most commonly used diagnostic techniques. The cysts were located in the right lung in 68 patients (66.6%), in the left lung in 30 patients (29.4%), in both lungs in four patients (3.9%). Concomitant liver cyst hydatid was also detected in 12 patients that were located at right lung, and two patients with bilateral lung involvement. All cases were managed surgically. Of 14 cases with concomitant liver and intrathoracic hydatid cysts, right thoracophrenotomy was performed in 12, median sternotomy in one, and phrenotomy in other. Partial cystectomy and capitonnage were the most commonly used surgical methods. Post-operative complication was seen in 10 (9.8%) patients. Infection at the incision site occurred in four patients and air leakage in three. Complications of capitonnage were seen in three patients. One patient (1%) died at fourth post-operative day due to sepsis. Parenchyma protective operations should be performed especially in children living in endemic areas because of the possibility of recurrence of the disease in the future. Single stage operations in suitable cases decrease the cost of treatment and make surgical therapy suitable in both children and young adults, by reducing the hospital in-patient time and morbidity. [source] One-lung ventilation of a preterm newborn during esophageal atresia and tracheoesophageal fistula repairACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 3 2002E. Tercan In this paper, we assessed the anesthesia management of a male, a 34-week gestation age newborn, weighing 1500 g, who has esophageal atresia and tracheoesophageal fistula localized just above the carina. Endotracheal intubation and intermittent positive pressure ventilation caused air leakage through the fistula into the stomach, causing abdominal distention. One-lung ventilation by left main bronchus intubation eliminated this problem. [source] Robotic-assisted single-incision right colectomy: early experienceTHE INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY, Issue 4 2009Matthew B. Ostrowitz Abstract Background Application of laparoendoscopic single-site surgery (LESS) is increasing across surgical disciplines. In addition to the possibility of decreased postoperative pain, LESS offers better cosmesis with virtually ,scarless' surgeries, while avoiding the increased costs and complexity of natural orifice surgery. Instrument conflict minimization often requires the crossing of articulating instruments, which we believe can be more intuitively facilitated using the daVinci-S® robotic system. We describe our early experience with three robotic single-incision right hemicolectomies. Methods Three robotic single-incision right hemicolectomies were performed using the daVinci-S robotic system, utilizing a single 4 cm incision through or around the umbilicus. The procedure was performed using three robotic arms, a 12 mm camera and two 8 mm robotic ports. A medial to lateral approach was used and an extracorporeal resection and anastomosis was performed after undocking the robot. Results There were no intraoperative or postoperative complications. Average operative time was 152 min. The first case was converted to non-robotic single-incision right hemicolectomy during mobilization of the ascending colon, due to uncontrollable air leakage around the ports. The second and third cases were successfully completed without air loss by purse-stringing sutures around each individual port and the use of the SILSÔ port, respectively. Conclusions Robotic-assisted single-incision right hemicolectomy can be successfully and safely performed using the daVinci-S robotic system. Several techniques may be employed to prevent the loss of pneumoperitoneum. We believe right hemicolectomy lends itself to single-site surgery because specimen extraction requires a 4 cm incision and may confer patient benefit, with decreased postoperative pain and improved cosmesis. By crossing the robotic instruments and reassigning control of the arms, the robot represents a means to help perform these procedures safely by allowing them to be performed in a more intuitive fashion.

Rocha Abstract The wide use of biological sealants as a reinforcement for arterial sutures and the small experimental base in literature motivated this study. Our aim was to evaluate the flow, tear pressure, and the need of reinforcement stitches in sutured arteries after a cross-section. This research project complied with the Helsinki convention. The Tissucol (Baxter) fibrin sealant was used in all experiments. The femoral and carotid arteries of 17 swine from the same breed (weighing from 15 to 20 kg) were cross-sectioned after heparinization and subjected to anastomoses using a single continuous plane of 7-0 prolene. We worked with 68 artery samples, 34 in the treatment group and 34 in the control group. For each animal, one carotid and one femoral artery randomly received fibrin sealant with the contralateral side being used as a control. The need and the number of reinforcement stitches were recorded. Ten minutes after protamine infusion, the animals were sacrificed and the arteries were catheterized respecting 1 cm proximal and distal. The arteries were measured and placed on a flow meter to evaluate the flow rate of 10 mL of 0.9% NaCl in a 50 cm high column. The arteries were then subjected to air infusion at increasingly higher pressures (stepwise increases of 25 mm Hg), the grafts were dipped in 0.9% NaCl solution, the first air leakage was observed, and the tear pressure recorded. Data was analyzed with EpiInfo 6 data manager. The external diameters and thickness of the arteries were similar in both the treatment and control group. There was no significant difference between the groups regarding the tear pressure (P = 0.329), flow rate (P = 0.943), and the number of samples with a tear pressure above 200 mm Hg. However, the sealant reduced the number of reinforcement stitches necessary (P = 0.029). We conclude that fibrin sealant reduces the need of additional stitches; however, it does not change the tear pressure nor significantly reduces the flow. [source] | ||||||||||
