OBJECTIVE: To evaluate the impact of pneumoperitoneum time on intravesical recurrence (IVR) in upper tract urothelial carcinoma (UTUC) patients who underwent laparoscopic radical nephroureterectomy (LRNU). PATIENTS AND METHODS: We identified 129 UTUC patients who underwent LRNU at our three institutions from 2004 to 2014. We evaluated the association of IVR rate and patient clinico-pathological characteristics including operation time. By retrospectively reviewing all videotapes, we defined pneumoperitoneum time as being from the infusion of pressurized CO2 gas with a pressure of 10-12 mmHg to extirpation of the kidney...

This report presents a case of a 46-year-old woman in whom contralateral pneumothorax occurred during retroperitoneal laparoscopic donor nephrectomy without any evidence of diaphragmatic injuries. After the start of carbon dioxide-induced pneumoperitoneum, the patient's end-tidal carbon dioxide pressure and heart rate suddenly increased. The surgery was then paused, and a chest X-ray revealed a right pneumothorax accompanied by pneumomediastinum. After a thoracostomy tube was inserted, these symptoms immediately improved...

BACKGROUND: There is an upward surge in the use of laparoscopic surgeries due to various advantages when compared to open surgeries. Major advantages are, due to small incisions which are cosmetically acceptable and most of them are now daycare procedures. Problem of economic burden and hospital bed occupancy has been overcome with laparoscopic surgeries. All these advantages are not free from disadvantages, as hemodynamic changes such as hypertension; tachycardia and other surgical-related complications are commonly observed intraoperatively...

BACKGROUND: Pneumoperitoneum in laparoscopic procedures is associated with hemodynamic response, due to the release of catecholamines and vasopressin. Magnesium and clonidine have been used to attenuate such hemodynamic responses by inhibiting release of these mediators. We conducted this randomized, double-blinded study to assess which of the two attenuates hemodynamic response better. MATERIALS AND METHODS: Ninety American Society of Anesthesiologists health status Classes I and II patients posted for elective laparoscopic cholecystectomy were randomized into three groups of thirty patients each...

The purpose of this review is to, first, determine the static factors that affect the length of the human trachea across different populations and, second, to investigate whether or not there are dynamic factors that cause the length of the human trachea to vary within the same individual. We also investigated whether these changes in tracheal length within the same individual are significant enough to increase the risk of endobronchial intubation or accidental extubation. A PubMed/MEDLINE and a Web of Science database English-language literature search was conducted in May 2016 with relevant keywords and MeSH terms when available...

Achalasia refers to the lack of smooth muscle relaxation of the distal esophagus. Although nonsurgical treatments such as pneumatic dilatation of the distal esophagus and botulinum toxin injections have been performed, these procedures have limited duration. Similarly, surgical treatment with Heller myotomy is associated with complications. At our institution, we perform the peroral endoscopic myotomy (POEM) in qualified patients. Briefly, POEM involves endoscopic creation of a mid-esophageal submucosal bleb, creation of a submucosal tunnel with the endoscope, and then a distal myotomy, resulting in relaxation of the distal esophagus...

Background. Although the advantages of laparoscopic cholecystectomy (LC) over open cholecystectomy are immediately obvious and appreciated, several patients need a postoperative hospital stay of more than 24 hours. Thus, the predictive factors for this longer stay need to be investigated. The aim of this study was to identify the causes of a long hospital stay after LC. Methods. This is a retrospective cohort study with 500 successful elective LC patients being included in the analysis. Short hospital stay was defined as being discharged within 24 hours after the operation, whereas long hospital stay was defined as the need for a stay of more than 24 hours after the operation...

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery performed worldwide. Improvements in LSG have been suggested to achieve better weight loss or to lessen the complications rates. We propose a change in the standard technique to privilege the use of thinner instruments, the needlescopic sleeve gastrectomy (NSG). METHODS: A 40-year-old female, BMI 40, with no previous abdominal surgery was selected for a NSG. She was placed in a semi-sitting position with the surgeon standing between the legs...

We describe the first case of severe hypernatremia associated to laparoscopic surgery for hydatid cyst in an adult patient after the use of hypertonic saline solution with complete resolution. Severe hypernatremia is an unusual fact at the immediate postoperative period but may have fatal consequences for the patient and need immediate action. The patient reached a serum sodium concentration of 179 mmol/L without adverse effects after 6 days of treatment. Laparoscopy could play a crucial role in Na(+) absorption due to high intraabdominal pressure caused by the pneumoperitoneum and its limitations to avoid peritoneal absorption of hypertonic saline solution...
