When and how should peritoneal endometriosis be operated on in order to improve fertility rates and symptoms? The experience and outcomes of nearly 1…

2021

Abstract Purpose To analyze the follow-up results of patients suffering from symptomatic early-stage endometriosis after a consistent laparoscopic peritoneal stripping of the altered peritoneum (peritoneal endometriosis and surrounding inflamed tissue) was performed. This type of endometriosis is resistant to medical therapy and/or impairs fertility. Methods Using our prospectively maintained database, we were able to identify all symptomatic women with the suspicion of only peritoneal endometriosis who underwent laparoscopy at our endometriosis center over a period of 5 years. All procedures were carried out in a standardized fashion by one single surgeon, who is highly experienced in mini…

Effect of depth of neuromuscular blockade on the abdominal space during pneumoperitoneum establishment in laparoscopic surgery.

2015

To evaluate the effect of neuromuscular blockade (NMB) upon the abdominal space during pneumoperitoneum establishment in laparoscopic surgery, comparing moderate NMB and deep NMB.Prospective, randomized, crossover clinical trial.Operating room.Seventy-six American Society of Anesthesiologists 1 to 2 patients scheduled for elective laparoscopic surgery.Two independent evaluations were performed at the establishment of pneumoperitoneum for a preset intraabdominal pressures (IAPs) of 8 and 12 mm Hg, both during moderate NMB (train-of-four count, 1-3) and deep NMB (posttetanic count,5). Rocuronium was used to induce NMB, and sugammadex was used for reversal.We evaluated (i) the volume of CO2 in…

High-intensity transient signals during laparoscopic surgery in children.

2009

Background Laparoscopic interventions in children gain increasing popularity. Pneumoperitoneum as applied during laparoscopic surgery can induce gas emboli formation, but it is unclear whether this is associated with cerebral embolic events. To investigate the hypothesis that pneumoperitoneum causes cerebral emboli in children, the number and intensity of high-intensity transient signals (HITS) detected using transcranial Doppler ultrasonography were assessed before and after induction of pneumoperitoneum. Methods Twenty children were monitored during laparoscopic surgery. General anaesthesia was performed using sevoflurane and sufentanil or alfentanil. Pressure-controlled ventilation was a…

Surgical Advances in the Treatment of Abdominal Wall Hernias

2015

In the last two decades, the surgery of the abdominal wall has experienced an important development from being considered a matter of little interest for general surgeon, to having a greater presence at scientific meetings and to being increasingly prominent in the specialist training in surgery. In 1990 the plastic surgeon Oscar Ramirez published a method to repair defects in the abdominal wall that called “Component Separation Technique” thereafter general surgeons fixed his attention on the techniques of autoplastic repair of the abdominal wall that had already developed throughout the twentieth century. This interest grows with the emergence of new prosthesis and the use of laparoscopic…

Deficient cytokine response of human allergen-specific T lymphocytes from humanized SCID mice and reconstitution by professional antigen-presenting c…

2000

Abstract Background: Hu-PBL-SCID mice generated by the transfer of PBMCs from atopic individuals may provide a physiologic in vivo model for investigating human responses to allergens and potential approaches toward immunotherapy. Objective: This study was undertaken to investigate the functional activity and cytokine profile of human allergen-reactive T lymphocytes isolated from hu-PBL-SCID mice. Methods: PBMCs from allergic individuals were coinjected with allergen into SCID mice. Human lymphocyte migration and phenotype were established by reverse transcription–PCR and immunohistochemistry, IgE levels in sera were determined, and the frequency of allergen-reactive cytokine-producing T ly…

Microlaparoscopic Hernia Repair in Children

2011

Introduction. This study reports the authors’ experience with the exclusive use of 2-mm instrument sets and small diameter scopes in 100 children undergoing microlaparoscopic herniorrhaphy. Method. This prospective study was designed as a pilot feasibility study; all data related to patients and procedures were prospectively collected. A pneumoperitoneum was established, and 1.7 to 2 mm 0° or 30° scopes were introduced for visualization. Exclusively 2-mm instruments were used. Results. This study included 100 children (aged 15 days to 11 years, median age 2.3 years) undergoing microlaparoscopic hernia repair. A total of 140 hernias were treated. The average operative time for the microlapa…

Time course of cerebrovascular autoregulation during extreme Trendelenburg position for robotic-assisted prostatic surgery

2013

Trendelenburg positioning in combination with pneumoperitoneum during robotic-assisted prostatic surgery possibly impairs cerebrovascular autoregulation. If cerebrovascular autoregulation is disturbed, arterial hypertension might induce cerebral hyperaemia and brain oedema, while low arterial blood pressure can induce cerebral ischaemia. The time course of cerebrovascular autoregulation was investigated during use of the Trendelenburg position and a pneumoperitoneum for robotic-assisted prostatic surgery using transcranial Doppler ultrasound. Cerebral blood flow velocity was correlated with arterial blood pressure and the autoregulation index (Mx) was calculated. In 23 male patients, Mx was…

Epidemiology, Management, and Survival of Peritoneal Carcinomatosis from Colorectal Cancer

2015

Modern chemotherapy aims to improve long-term survival for selected patients with peritoneal carcinomatosis. Publications suggest promising results, but the spread of these new aggressive treatment strategies in the general population is not well known.The aim of this study was to draw a picture of epidemiology, management, and survival in synchronous and metachronous peritoneal carcinomatosis from colorectal cancer.The cumulative risk of metachronous peritoneal carcinomatosis was estimated in patients resected for cure. Net survival rates were calculated for synchronous and metachronous peritoneal carcinomatosis.The study was conducted with the use of the Burgundy Digestive Cancer Registry…

Neutral pH and low–glucose degradation product dialysis fluids induce major early alterations of the peritoneal membrane in children on peritoneal di…

2018

WOS: 000439138700024 PubMed ID: 29776755 The effect of peritoneal dialysates with low-glucose degradation products on peritoneal membrane morphology is largely unknown, with functional relevancy predominantly derived from experimental studies. To investigate this, we performed automated quantitative histomorphometry and molecular analyses on 256 standardized peritoneal and 172 omental specimens from 56 children with normal renal function, 90 children with end-stage kidney disease at time of catheter insertion, and 82 children undergoing peritoneal dialysis using dialysates with low-glucose degradation products. Follow-up biopsies were obtained from 24 children after a median peritoneal dial…
