Hypothesis: Laparoscopy has become a popular approach for the surgical treatment of benign and even malignant colorectal diseases. Several authors have reported better preserved immunity in patients undergoing laparoscopic compared with conventional colorectal surgery. The present study addresses the hypothesis that specific and nonspecific immunity are differently affected by laparoscopic and conventional colorectal surgery. Design: Nonrandomized control trial. Setting: University hospital. Patients: Seventy prospectively enrolled patients with colorectal diseases undergoing laparoscopic (n=35) or open (n=35) surgery. Main Outcome Measures: Blood samples were taken prior to surgery as well as on days 1, 3, and 5 after surgery. Cell numbers of lymphocyte subpopulations as well as natural killer cells were determined by flow cytometry, and interleukin 6 and C-reactive protein serum levels were measured. Results: Significant differences between study and control patients (PϽ.05) were detected regarding circulating interleukin 6 and C-reactive protein levels with a reduced proinflammatory response to surgery in patients after laparoscopic surgery. Furthermore, postoperative natural killer cell counts were significantly higher in patients after laparoscopic surgery. The levels of B lymphocytes and T lymphocytes and helper T-cell counts and cytotoxic (suppressor) T-cell counts did not show significant differences after open or laparoscopic surgery. Conclusions: Our findings indicate a less pronounced proinflammatory response to surgical trauma in patients after minimally invasive surgery. The nonspecific immune response appears to be less affected by laparoscopic surgery when compared with open surgery while the specific cell-mediated immunity is equally affected. These findings are important because a divergent effect on specific and nonspecific immunity of laparoscopic surgery for colorectal disease has not been reported before.
The S3-guidelines contain evidence-based recommendations for the indication, selection of procedure, technique, and follow-up. Patient care should improve after implementation of these guidelines in clinical practice. Compliance by decision makers and health insurers is warranted.
The guideline contains recommendations based on the scientific evidence and on a consensus of experts from multiple disciplines about the indications for bariatric surgery, the choice of procedure, techniques, and follow-up care. It should be broadly implemented to improve patient care in this field.
Rendezvous procedures offer a safe, minimal-invasive therapeutic approach allowing the resection of benign sessile or colonoscopically inaccessible localized polyps and of early stage colon cancer.
Laparoscopic diaphragmatic plication provides excellent relief of symptoms caused by diaphragmatic paralysis. There is no perioperative morbidity, and hospital stay is short. The laparoscopic approach, therefore, is an attractive surgical alternative for the treatment of phrenic nerve palsy and should be considered in all suitable patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
