Our study discloses important issues regarding the use of intravenous and epidural analgesia and postoperative patient monitoring in Greek hospitals. Implementation of acute pain services that are satisfying the quality criteria may help to improve patient care.

BackgroundPatient satisfaction is an increasingly appreciated measure of outcome for health care procedures. The purpose of this study was to evaluate Greek surgical patients’ satisfaction with perioperative anesthetic services and to determine which factors maximize satisfaction level through all phases of perioperative care.MethodsAdult Greek patients admitted for elective surgery in an academic hospital were included in the study. Three separate questionnaires were constructed: Q1 (patients who underwent general anesthesia alone or combined with epidural) and Q2 (patients who received regional anesthesia alone) covered perioperative anesthetic care; Q3 covered postoperative analgesia services in the ward (patient-controlled analgesia or epidural analgesia) provided by our anesthesiologist-centered analgesia care team. Principal component analysis with varimax rotation was used separately for each questionnaire, and extracted factors were entered into multiple logistic regression with patient satisfaction as the dependent binary variable. Statistical significance level was set at P < 0.05.ResultsThree hundred and forty-five patients were included. Q1 questionnaire (answered by 282 patients) included four dimensions: communication with the anesthesiologist, sense of cold/shivering, pain, and nausea. Q2 questionnaire (answered by 63 patients) included three dimensions: communication with the anesthesiologist, sense of cold/shivering, and nausea/anxiety. Q3 questionnaire (answered by 237 patients) included five dimensions: anesthesiologist intervention upon symptoms, pain, care by the anesthesiologist/physical activity, nausea/vomiting, and anesthesiologist behavior. The communication dimension score in Q1 and Q2, sense of shivering in Q2, and pain management and anesthesiologist behavior dimension scores in Q3 were significantly associated with patient satisfaction. Overall satisfaction rates were high (according to the questionnaire, the observed percentage was in the range of 96.3%–98.6%).ConclusionGreek surgical patients reported high satisfaction with perioperative anesthesia care. Interaction between patient and anesthesiologists during all periods of study, absence of shivering in regional anesthesia, and adequate postoperative pain control in the ward were significant predictors of patient satisfaction in the present Greek surgical population.

Although the use of laparoscopic surgery is increasing, controversy still surrounds its application for malignant conditions. Gastrointestinal stromal tumours (GISTs) are less demanding in terms of lymphadenectomy, meaning that laparoscopic resection might have a more defined benefit when compared with open resection. To the best of our knowledge, no randomized study exists that compares the laparoscopic and open resection of GISTs. The current study aimed to examine the relevant literature by means of a systematic review. A systematic literature search was performed individually by two authors, in which three independent databases were searched using specific search-terms. Titles, abstracts and full texts were screened, as well as references to relevant articles, in order to comprise a comprehensive list of studies. Data were extracted using a detailed pre-agreed spreadsheet. Studies were evaluated according to the modified MINORS criteria. A total of 10 studies were included in the present review, yielding a total of 14 entries. The majority of studies reported significantly improved perioperative outcomes for the laparoscopic approach, including improved duration of operation, blood loss and length of hospital stay. Only four studies reported long-term outcomes and findings that were controversial, with some studies detecting no statistically significant differences, one reporting improved and one reporting worse disease-free and overall survival for the laparoscopic group. Three studies were deemed to be good quality, two of which had not reported significantly different long-term outcomes, while the third had reported significantly improved outcomes in the open resection group. While there is a clear benefit for performing laparoscopic surgery in patients with GIST with regards to perioperative outcomes, when it comes to long-term oncological outcomes, uncertainty over its application remains. The lack of randomized trials, as well as the poor reporting of retrospective studies, limits the amount of evidence that is currently available. Laparoscopic surgery for GIST is certainly safe, feasible and likely cost-effective; however, further studies are required to inform on whether this technique is superior to open resection.

Background: Complement deficiency predisposes to autoimmune renal disease. Since complement deficient mice are increasingly used to study the immunopathogenesis of renal disease we have determined whether mice deficient in C3 or C4 are susceptible to spontaneous immune-mediated renal injury. Methods: C3-deficient, C4-deficient and complement-sufficient, wild-type mice were maintained in standard conditions for 1 year at which stage renal function, renal histology, circulating antibody and autoantibody levels were assessed. Results: No significant decline in renal function was demonstrated in the complement-deficient mice. However, there was histological evidence of glomerular injury in both the C3- and C4-deficient mice, but of insufficient severity to alter function. Serum IgG2a concentration was significantly lower in C3- and C4-deficient mice. In contrast C3-deficient mice had higher concentrations of serum IgG2b. There was a tendency for mice from all groups, including the complement-sufficient mice, to develop autoantibodies. C4-deficient mice had higher titres of anti-dsDNA IgG but otherwise deficient mice had similar autoantibody titres to controls. Conclusion: We conclude that C4-deficient mice demonstrate a small increase in autoantibody production at 1 year of age compared to C3-deficient and wild-type mice. Furthermore, although complement-deficient mice exhibit glomerular changes, they are of minor functional significance, and are unlikely to affect the study of experimentally induced renal disease in these mice.
