“…With the exception of the lower peritoneal IL-6 response, the local cytokine response was otherwise similar after laparoscopy compared with laparotomy, with no difference in the three other cytokines measured. This may be because of the known local immunologic effects of desiccation and acidification caused by the formation of carbonic acid during carbon dioxide pneumoperitoneum [20,[59][60][61][62][63][64][65][66][67][68].…”

“…Few reports of adhesions after laparoscopy exist [7][8][9]. Experimental studies have demonstrated that several factors, such as CO 2 -induced acidosis and metabolic hypoxemia, temperature, and duration of the intervention, are important in the formation of adhesions at laparoscopy [10]. In an experimental model in pigs, it was reported recently that the incidence of intra-abdominal adhesions was lower after laparoscopic compared with open cholecystectomy [11].…”

Bowel obstruction after laparoscopic and open colon resection for cancer: Results of 5 years of follow-up in a randomized trial

et al. 2011

Background Postoperative bowel obstruction caused by intra-abdominal adhesions occurs after all types of abdominal surgery. It has been suggested that the laparoscopic technique should reduce the risk for adhesion formation and thus for postoperative bowel obstruction. This study was designed to compare the incidence of bowel obstruction in a randomized trial where laparoscopic and open resection for colon cancer was compared. Methods A retrospective analysis was performed, collecting data of episodes of bowel obstruction with or without surgery. Only episodes treated in the hospital where the index surgery took place were included. Data for 786 patients were collected for the 5-year period after cancer surgery. Results Baseline characteristics for the evaluated laparoscopic (n = 383) and open (n = 403) groups were comparable. The cumulative obstruction percentages at 5 years for the open and laparoscopic groups were 6.5 and 5.1% respectively and did not significantly differ from each other. Tumor stage seemed to influence the risk for bowel obstruction: 2.8% in stage I, 6.6% in stage II, and 7% in stage III, but the differences were not significant. Conclusions This analysis does not support the hypothesis that laparoscopy leads to fewer episodes of bowel obstruction compared with open surgery.Surgical trauma is the cause of more than 90% of intraabdominal adhesions, and approximately 30% of patients who undergo major surgery develop postoperative

“…A elevação da pressão intraperitoneal e potencial absorção de CO 2 , condição que pode levar a aumento significativo da pressão parcial de CO 2 e diminuição da pressão parcial arterial de O 2 (Vannozzi et al 2002), podem causar alterações no equilíbrio acidobásico, ventilatórias e hemodinâ-micas, além de hipercapnia e acidose (Botter et al 2005, Bergstrom et al 2007, porém em todos os procedimentos não houve alterações mensuráveis compatíveis com as citadas.…”

Pesq. Vet. Bras. 33(7):920-923, julho 2013 920 RESUMO.-O presente trabalho objetivou avaliar uma técni-ca de vasectomia laparoscópica em macacos-prego (Cebus nigritus). Para tanto, foram utilizados oito animais submetidos à anestesia geral inalatória. Foram introduzidos três portais (dois de 5mm e um de 10mm) na parede abdominal ventral. Os ductos deferentes foram isolados, cauterizados com energia bipolar e seccionados próximo ao anel inguinal interno. Os procedimentos duraram 30,67+8,78 min. sem a ocorrência de complicações trans ou pós-operatórias o que permite concluir que a técnica proposta é adequada para essa espécie.

Peritoneal and systemic pH during pneumoperitoneum with CO2 and helium in a pig model

Abstract: Insufflation of CO(2) into the peritoneal cavity seemed to result in an immediate decrease in peritoneal pH, a response that might influence biological events. This peritoneal effect also seems to influence systemic acid-base balance, probably due to trans-peritoneal absorption.
