BACKGROUND: Positive end-expiratory pressure (PEEP) can increase intracranial pressure. Pneumoperitoneum and the Trendelenburg position are associated with an increased intracranial pressure. We investigated whether PEEP ventilation could additionally influence the sonographic optic nerve sheath diameter as a surrogate for intracranial pressure during pneumoperitoneum combined with the Trendelenburg position in patients undergoing robot-assisted laparoscopic prostatectomy. METHODS: After anesthetic induction, 38 patients were randomly allocated to a low tidal volume ventilation (8 ml/kg) without PEEP group (zero end-expiratory pressure [ZEEP] group, n = 19) or low tidal volume ventilation with 8 cmH2O PEEP group (PEEP group, n = 19)...

This is a case of a 54-year-old gentleman who presented to an outside hospital emergency department with lower abdominal pain. Computed tomography imaging showed a small amount of intraperitoneal free air and cystic pneumatosis coli. He was admitted, managed conservatively with intravenous antibiotics, and then discharged home after his symptoms improved. Elective laparoscopic sigmoid colectomy was subsequently performed with intraoperative findings of partial sigmoid volvulus and extensive pneumatosis coli of the sigmoid colon...

INTRODUCTION: Benign pneumoperitoneum (BPPT) is defined as asymptomatic free intraabdominal air or as pneumoperitoneum without peritonitis. Symptomatic free air requires surgical anagement, but management of asymptomatic pneumoperitoneum is controversial. In this study, we investigate the diagnosis and treatment of BPPT in children. CLINICAL FINDINGS: The clinical data of 9 pediatric patients with BPPT who were admitted to our hospital from January 2000 to January 2015 were retrospectively analyzed to summarize the diagnosis and treatment...

Importance: Necrotizing enterocolitis (NEC) is a major cause of neonatal morbidity and mortality. Preventive and therapeutic research, surveillance, and quality improvement initiatives are hindered by variations in case definitions. Objective: To develop a gestational age (GA)-specific case definition for NEC. Design, Setting, and Participants: We conducted a prospective 34-month population study using clinician-recorded findings from the UK National Neonatal Research Database between December 2011 and September 2014 across all 163 neonatal units in England...

BACKGROUND: Post-laparoscopic shoulder pain (PLSP) frequently follows a laparoscopic cholecystectomy. A proposed mechanism for PLSP is the irritation or injury of the phrenic nerve by the CO2 pneumoperitoneum during laparoscopic surgery. Here, we investigated whether a phrenic nerve block (PNB), performed under ultrasound guidance, could reduce the incidence and severity of PLSP after laparoscopic cholecystectomy. METHOD: Sixty patients were randomized into two groups, with one group receiving PNB with 4 ml (30 mg) of 0...

BACKGROUND: Laparoscopic operations have become longer and more complex and applied to a broader patient population in the last decades. Prolonged gynecological laparoscopic surgeries require prolonged pneumoperitoneum and Trendelenburg position, which can influence respiratory dynamics and other measurements of pulmonary function. We investigated the differences between volume-controlled ventilation (VCV) and pressure-controlled ventilation (PCV) and tried to determine the more efficient ventilation mode during prolonged pneumoperitoneum in gynecological laparoscopy...

INTRODUCTION: Natural orifice transluminal endoscopic surgery (NOTES) is a challenging minimally invasive procedure. Although laparoscopic techniques for liver resection are gaining acceptance worldwide, few studies have investigated NOTES liver resection. We used a porcine model to assess the feasibility and safety of transvaginal NOTES liver resection (TV NOTES LR). MATERIALS AND METHODS: Nine female pigs underwent TV NOTES LR. A nonsurvival acute porcine model with general anesthesia was used in all cases...

BACKGROUND: Conventional pneumoperitoneum (CP) and automatically maintained pneumoperitoneum using AirSeal Intelligent Flow System (AiFS) were compared during pediatric laparoscopic appendectomy (LA) using intraperitoneal pressure (IPP) and hemodynamic parameters. METHODS: A prospective review of 39 children aged 3-14years who had standard 3-trocar LA was performed. Pneumoperitoneum was either AiFS (n=18) or CP (n=21) according to the surgeon's preference. IPP during insertion of trocars in all subjects was initially 8-10mmHg, which was reduced to 5mmHg then maintained until LA was completed...

BACKGROUND: Intra-abdominal hypertension (IAH) impairs cardiovascular function, however an effect of IAH on cardiac electrophysiology has been poorly documented. The aim of this study was to evaluate the effect of IAH following pneumoperitoneum on vectorcardiographic variables reflecting cardiac repolarisation and depolarisation. METHODS: Otherwise healthy women undergoing elective gynaecological laparoscopy were studied. Intra-abdominal pressure (IAP), spatial QRS-T angle and ST-segment J-point (STJ) were observed during surgery and the early postoperative period...

BACKGROUND AND OBJECTIVES: Pneumoperitoneum during laparoscopy can produce changes in intraocular pressure (IOP) that may be influenced by several factors. In this study, we investigated changes in IOP during laparoscopy with different positioning. METHODS: We recruited adult patients without eye disease scheduled to undergo laparoscopic operation requiring a reverse Trendelenburg tilt (rTr; group A; n = 20) or Trendelenburg tilt (Tr; Group B; n = 20). IOP was measured at 7 time points (T1-T7)...

BACKGROUND: Splenic abscesses are rare entities; reports are commonly described in immunocompromised patients (72%) as: hematologic diseases, diabetes, endocarditis, acquired immunodeficiency syndrome, transplant patients and subjects who had abdominal trauma or splenic infarction. The main and most serious complication is the abscess rupture into the peritoneal cavity or adjacent organs (stomach or colon), which determines hemodynamic instability or septic state. CLINICAL CASE: Fifty-year-old man, who was admitted at Emergency Room due eight days' progressive, oppressive, and current pain; intensity 4/10, irradiated at hemi-back, which was higher intensity during the standing and decreased at supine position...

An acute dry cough results commonly from bronchitis or pneumonia. When a patient presents with signs of infection, respiratory crackles, and a positive chest radiograph, the diagnosis of pneumonia is more common. Antibiotic failure in a patient being treated for community-acquired pneumonia requires further investigation through chest computed tomography. If a lung mass is found on chest computed tomography, lung empyema, abscess, and cancer need to be included on the differential and managed aggressively. This report describes a 55-year-old Caucasian male, with a history of obesity, recovered alcoholism, hypercholesterolemia, and hypertension, presenting with an acute dry cough in the primary care setting...

INTRODUCTION: Traditional laparaendoscopic surgery using CO2 pneumoperitoneum is associated with complications and the existing gasless laparaendoscopic surgery has shortcomings such as poor visibility in the operation field. To overcome the disadvantages of the current lifting gasless laparaendoscopic operation platforms, we developed an inflatable device for gasless laparoscopic operation field formation (LOFF) that can be internally installed and applied in practice. METHODS: We initially designed operation platforms for gasless laparaendoscopic single-port (GLESP) surgery...

OBJECTIVE: General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10cmH2O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and systemic stress response in laparoscopic cholecystectomy. METHODS: American Society of Anesthesiologist I-II physical status 43 patients scheduled for laparoscopic cholecystectomy were randomly selected to receive external PEEP of 5cmH2O (PEEP 5 group) or 10cmH2O PEEP (PEEP 10 group) during pneumoperitoneum...

INTRODUCTION: For the treatment of patients with end-stage renal disease, kidney transplantation is preferred to renal replacement modalities such as hemodialysis and peritoneal dialysis. Although open surgery remains the gold standard, minimally invasive approaches have recently been applied in transplant kidney surgery. Despite growing enthusiasm and potential benefits of robotic kidney transplant, many aspects of this novel technique remain controversial. Aim of this study was to analyze the current status and future developments in robotic-assisted surgery for kidney transplantation...
