The stress response to laparoscopic cholecystectomy: investigation of endocrine parameters.

Laparoscopic cholecystectomy, as a typical example of minimal invasive surgery, is associated with low complication rates and minimal patient discomfort, and provides the same safety as conventional cholecystectomy. In the present prospective observational study, endocrine parameters as indicators for stress response were measured. We investigated 53 patient with laparoscopy cholecystectomy and 12 patients with conventional cholecystectomy. Blood samples were taken pre-, peri-, and postoperatively for measurement of ACTH, cortisol, prolactin, and growth hormone. General anesthesia followed a standardized protocol. The increase in all stress hormones did not differ between patients in the two groups, and was comparable with that reported in the literature and the findings of our own previous studies in patients undergoing conventional cholecystectomy and elective colon resection. We conclude that laparoscopic cholecystectomy is associated with a pronounced endocrine stress response that does not account for the observed differences in the peri- and postoperative complication rate or patient comfort.

[Do costs decide? Disposable or reusable instruments in laparoscopic cholecystectomy?].

UNLABELLED: Laparoscopic cholecystectomy requires new and specially designed instruments. Both, disposable and reusable instruments are available and frequently used. The purpose of this analysis was to compare these instruments with regard to safety and costs. A complete and detailed calculation comprising all cost components was performed using data from 534 patients. SAFETY of the procedure was assessed by the documentation of all events during and after laparoscopic cholecystectomy in 1000 consecutive patients. COSTS: A standard operation with reusable instruments costs DM 3395. One third of these costs are non-hospital costs. Every postoperative day in hospital adds DM 234.44, every minute of operation time adds DM 4.88. Using a complete of disposable instruments causes an increase in total costs of DM 1117, which mainly results from the costs of the instruments themselves. SAFETY: Among 1000 operations all performed with reusable instruments, 82.3% were uneventful for the patient. The wound infection rate was 2.3%. Until today no injuries of the staff caused by these instruments were observed. These findings demonstrate that reusable instruments are safe and cost-effective.

[Laparoscopic and conventional suture of perforated peptic ulcers--a comparison].

After the first successful laparoscopic closure of a perforated peptic ulcer in 1990, 13 consecutive patients with laparoscopic closure were compared to 8 previous patients with conventional surgery. The endpoints adverse advents (complications), pain intensity, fever, leucocytosis and hospital stay showed no clinically relevant differences. Consumption of analgesics was lower in the laparoscopy group. Laparoscopic closure of perforated peptic ulcer is technically feasible. The safety of the method and the benefit for the patient need proof by a randomized controlled trial.

[Laparoscopic or classical appendectomy? A prospective randomized study].

Though laparoscopic appendectomy started endoscopic surgery in general surgery, it has yet not reached the acceptance as is the case with cholecystectomy. The application of this technique in possibly bland appendices and reports that the technique was accompanied by severe complications, increases the scepticism about it. This made us decide to start a randomized controlled trial: laparoscopic vs. conventional appendectomy. More than 1000 endoscopic interventions mainly performed at the gallbladder and the stomach and 165 prospectively documented and partly treated patients with acute appendicitis were the basis to start this trial. "Acute Appendicitis" was diagnosed on the basis of clinical symptoms by means of the computer-aided questionnaire of the EC-study "Acute Abdominal Pain", a self-developed validated diagnostic score, the macroscopic findings and the careful assessment of the histology of the resected appendix. Beside the technical feasibility, principle end-points were mainly intensity and course of postoperative pain measured by means of the Visual Analogue Scale (VAS) in lying, standing and moving position and the postoperative consumption of analgesics. We assessed a difference of 15 points on the VAS as clinically relevant. Of 57 patients with acute appendicitis we performed open appendectomy in 23 and laparoscopy in 34 patients according to randomization. In 9 patients of the laparoscopy group it was necessary to change over to open appendectomy for different reasons resulting in a direct comparison of 25 laparoscopies versus 23 open appendectomies. There were no differences between sociodemographic and preclinical data in both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

[Instruments for measuring the quality of life of severely injured patients].

Trauma can be defined as either a somatic injury or a psychological reaction in the person affected. The emotional disturbances and psychosocial problems of trauma patients in particular, though still measurable a year or even longer after the event, have rarely been taken into account in surgical studies. Quality of life is a relevant endpoint in multiple trauma patients, insofar as rehabilitation seems to be complicated by non-efficient psychological coping. With reference to the prerequisites for a scientifically sound measuring method four instruments are described that seem to be suitable for measuring quality of life in multiple trauma patients. In addition, practical advice is given for the design of longitudinal studies focused on quality of life in trauma patients.

Assessment of emergency care in trauma patients.

There are many reasons for evaluation of an emergency care system, such as expenses (1.035 Bio. DM in 1985) and quality control. From January 1, 1987 to December 31, 1987 information on all patients seen by an emergency physician in the field have been recorded prospectively in a standard form by the Cologne emergency medical services. Cologne has 1,000,000 inhabitants and covers an area of 405 km2. The patients' status, diagnosis and therapeutic interventions were recorded. Trauma patients were further assessed as to time of accident, cause of accident, and trauma score. All trauma patients with a trauma score < 16 were followed up to their discharge from the hospital. In 1987, 2,073 trauma patients were treated. Overall mortality at the time of discharge was 9.2%. This result alone, however, is not sufficient for assessment of the trauma system. It is important to provide better information on the patient. The trauma evaluation score already used in the US became also a valid instrument in West-Germany. It shows a high correlation between survival and the patients' physiological status in the field. Standard curves could be established for comparing individual or regional trauma systems.

[Value of laparoscopy in diagnosis and therapy of the acute abdomen].

While diagnostic laparoscopy is a well established tool, therapeutic laparoscopy for acute abdominal disorders has recently been made possible by video-endoscopic techniques. From July 1989 to April 1992, 243 laparoscopic interventions were carried out in patients with an acute abdomen. After a pilot phase, patients with acute appendicitis were entered into a randomized trial, those with acute cholecystitis were operated within the next day list. Among the 243 operations were 202 appendectomies, 12 closures of perforated peptic ulcers, 4 successful interventions for intestinal obstruction, 4 irrigations for intraabdominal abscesses and 35 further operations, some of which had to be finished as laparotomies. Laparoscopic appendectomy was less painful but technically more difficult. In cases which needed bowel resection for ischemic necrosis or diverticular disease, conversion to open surgery had to be performed. Laparoscopic treatment of acute abdominal disorders including peritonitis can be effective and beneficial in one out of two patients. Adequate surgical training, expertise and respect to the safety of the patient are mandatory. The application of endoscopic suture devices will further enlarge the spectrum of laparoscopic treatment options for the acute abdomen.

[Patient-controlled analgesia (PCA) for postoperative pain relief. A prospective observational study for evaluating the technology in a ward routine].

Patient-controlled analgesia (PCA) is rarely used on surgical wards despite described advantages of this method as compared to conventional techniques. Uncertainties in patient selection and insufficient evaluation of this technique may explain these circumstances. The aim of our study was to evaluate PCA on general surgery and traumatology wards by means of standardized criteria for technology assessment (i.e. safety, practicability, benefit for patients and medical staff) and the efficacy of pain relief. In a prospective study we investigated 120 patients. In phase I, we performed analgesic therapy with tramadol/metamizol (50 ASA status I-IV patients). In phase II, piritramid had been applied to 70 ASA status I-II patients after an intermediate analysis of phase I. In 7% of the patients technical problems led to an early interruption even at the end of the study period. There were, however, no incidents which caused vital problems for the patients. A mean postoperative pain level of 55 visual analogue scale points (0-100 point scale) was achieved with tramadol/metamizol. PCA was stopped in 16% of the patients due to the occurrence of nausea or vomiting and in two patients due to insufficient pain relief. The use of piritramid in phase II led to lower pain levels and no interruptions of PCA because of ineffectivity or nausea/vomiting.(ABSTRACT TRUNCATED AT 250 WORDS)

[The incidence of postoperative pain on general surgical wards. Results of different evaluation procedures].

Knowledge of the incidence and significance of postoperative pain is essential for the establishment of effective pain treatment programmes. Detailed investigations on the incidence, severity and quality of postoperative pain from the surgeon's perspective are scarce in German hospitals. It was the aim of our study to investigate postoperative pain in general surgery under routine conditions. PATIENTS AND METHODS. A total of 168 patients scheduled for abdominal, vascular and orthopaedic surgery were investigated in a prospective trial. Pain was assessed by means of a 100-point visual analogue scale (VAS), a 5-point verbal rating scale (VRS), the original version of the McGill Pain Questionnaire (MPQ) and the short form of the McGill Pain Questionnaire (SFMPQ). These were applied preoperatively and daily thereafter up to the 7th postoperative day. Patients were randomly assigned into two groups with different sequences of application of the instruments. The pain treatment programme included intravenous analgesia with tramadol/metamizol (max. tramadol 400 mg+metamizol 5 g in any 24 h) after major surgery and additional administration of piritramide as needed (max. 60 mg/24 h.i.v.). After minor surgery ibuprofen was routinely given for analgesia (3 x 500 mg). RESULTS. All patients had pain on the days 1 and 2 postoperatively. The mean intensity of pain was 44 VAS points on day 1 and 6.8 points on day 7. The mean intensity of pain measured by the VRS on the 1st postoperative day was between "mild" and "moderate". The quality of pain showed a constant pattern concerning the mean scale values of descriptors of each subgroup (sensory, evaluative, affective, mixed) for both the original and the short form of the McGill Pain Questionnaire up to the 7th postoperative day. Sensory descriptors were reported more frequently than affective descriptors. Typical pain patterns were identified for different operations. After subtotal thyroidectomy, for example, patients perceived a high intensity of pain of short duration. In contrast, patients still have a high intensity of pain up to 7 days after abdominal and rectal operations. CONCLUSIONS. We conclude from our results that patients perceive significant postoperative pain under current standardized pain treatment in our department. Effective programmes for pain relief should take account of the different patterns of pain after different operations, as identified in this study.

[The Gastrointestinal Quality of Life Index. A clinical index for measuring patient status in gastroenterologic surgery].

Since the measurement of quality of life is a relevant endpoint of patient assessment, an international team of methodologists and surgeons have developed a new system-specific index. In different phases, items were collected, tested, rejected or retained and finally verified by international experts. The instrument was also validated against other generic measures, it was compared to 150 normals, tested for reproducibility with 50 stable patients and for responsiveness with 159 patients undergoing laparoscopic cholecystectomy. The product is a bilingual (German and English) questionnaire containing 36 items. Although further testing is in order, we conclude that the Gastrointestinal Quality-of-Life Index is ready to be used in clinical practice and research.

Evaluation of routine upper digestive tract endoscopy before laparoscopic cholecystectomy.

Endoscopy of the upper digestive tract was performed in 376 patients with symptomatic gallstone disease before elective laparoscopic cholecystectomy. Abnormalities were found in 60 patients (16.0 per cent); these included peptic ulcer (n = 14), gastric erosions (n = 15) and oesophagitis (n = 11). Thirty patients were treated medically and two by endoscopic polypectomy. In four patients endoscopy led to cancellation of cholecystectomy; in two the complaints have persisted. Statistical analysis of 28 variables showed few significant differences in symptoms between patients with normal and those with abnormal appearances at endoscopy. It is concluded that routine endoscopy before laparoscopic cholecystectomy is neither clinically useful nor cost effective in patients with symptomatic gallstone disease. This conclusion is related exclusively to patients with typical gallstone symptoms according to the definition used in this department.

[Acute pain in surgery: the significance of a neglected problem].

Acute pain represents a significant problem in surgical patients. However, the management of acute pain in Germany is unsatisfactory, mostly because surgeons are not interested in the pain of their patients, and anesthesiologists do not give pain treatment on surgical wards. The aim of this article is therefore to point out the significance of the problem of "acute pain" for surgeons. Basic knowledge of the production, perception and projection of pain as well as the special aspects of acute versus chronic pain is mandatory. Every surgeon should know about the predictors of postoperative pain, including the surgical and anesthesiological factors and patient characteristics. Efficient management of acute pain requires knowledge of the clinical significance of pain and the different methods for assessment. It is not sufficient to know the methods and advantages of appropriate management of acute pain; one must also understand the dangers. Problems caused by the treatment of pain should be recognized from a clinical point of view. Surgeons must take a greater interest in the problem of "pain", which should lead to the establishment of new concepts in the management of acute pain in surgical patients.
