Laparoscopic cholecystectomy: technical performance, safety and patient's benefit.

Laparoscopic cholecystectomy seems to be the most promising new technique for the treatment of symptomatic gallstone disease. For different reasons, controlled clinical trials comparing comfort and trauma for the patient of conventional versus laparoscopic cholecystectomy are difficult to perform at our institution. We therefore report on the results of our first 400 laparoscopic cholecystectomies using a strict and detailed protocol on technical performance, safety and benefit for the patient. Data was obtained immediately after the operation and after a short-term follow-up. To analyze the technical performance and the safety of the procedure, we developed a new classification system (I-V) of adverse events, including both the patients' and the surgeons' viewpoints. Our results show that in nearly 80% of the cases an optimal result (no adverse events in any respect) was obtained. For different reasons, the surgical procedure had to be changed during the operation in 20 cases (5%). In 3 cases (0.8%), an injury of the common bile duct occurred; 2 patients died (mortality 0.5%). On the first post-operative day, vomiting occurred in only 8% and nausea in 19% of the patients. Pain intensity was always below the level where patients demand analgesic medication and declined near zero the day after the operation. Patients fatigue was measured on a scale from 0-10 and rose from 2.2 preoperatively to 3.3 postoperatively. Only a short hospital stay of 3 days median was required. At short-term follow-up 6 weeks after the operation, pain was only rarely reported, the patients were fit and only 20% avoided some kind of food. We conclude that laparoscopic cholecystectomy is the treatment of choice for this precisely defined patient population with symptomatic gallstone disease.

Laparoscopic surgery in children and adolescents with suspected appendicitis: results of medical technology assessment.

Laparoscopy has been performed in 43 patients aged up to 18 years with suspected appendicitis; 20 were children 8-15 years and 23 adolescents 16-18 years of age. Diagnostic laparoscopy was successful in 36 (84%) patients; in 7 (16%) subsequent laparotomy was necessary to establish the diagnosis, in 4 (9%) because the appendix was not visualized. Laparoscopic appendectomy was done in 33 (77%) patients, additional laparoscopic adhesiolysis in four and inversion of a diverticulum in one. Changing to laparotomy during the laparoscopic operation was necessary in one patient because of a technical problem and in another because of bleeding of the appendicular artery. Laparoscopy was totally free of complications in 33 (77%) patients; another 9 (21%) had surgical or technical problems without negative outcome for the patient. In one (2%) patient a wound infection led to a negative outcome; there were no other laparoscopy-related events. The mean intensity of pain on the first day after laparoscopic appendectomy was 31 points (Visual Analogue Scale with 100 points) and decreased to nearly zero on the third day; 37% of patients needed opioids on the first and none on the third day. There was no statistical difference for pain intensity and consumption of analgesics after appendectomy via laparoscopy versus laparotomy. We conclude that diagnostic and therapeutic laparoscopy in children and adolescents with suspected appendicitis is a safe and effective procedure.

[Routine gastroscopy before laparoscopic cholecystectomy: evaluation of the technology in 376 patients].

We performed endoscopy of the upper digestive tract in 376 patients before elective laparoscopic cholecystectomy. Abnormalities were found in 60 (15.9%); 14 patients had peptic ulcers, 15 gastric erosions, and 11 oesophagitis. Because of endoscopic findings 30 patients were treated medically and 2 by endoscopic polypectomy. Endoscopy lead us to cancel cholecystectomy in 4 patients; in 2 the complaints have persisted. Patients with abnormal endoscopic findings showed few significant differences in 40 variables (history and symptoms) compared with patients with normal findings. The incidence of ulcers, erosions or oesophagitis in patients over 72 years of age without loss of weight was 28.6%, compared with an overall incidence of 10.6%. Endoscopy confined to this group of patients, however, would have shown only 15% of all lesions. Consequently these predictors for endoscopic abnormalities had no practical benefit. Technology assessment according to the criteria of Fineberg et al. showed a health improvement for only 2 patients (0.5%). We conclude that routine endoscopy before laparoscopic cholecystectomy is not clinically useful in patients with symptomatic gallstone disease. This is exclusively related to patients with typical gallstone symptoms according to our definition.

[Functional disorders after deep rectum resection: is pouch formation recommended?].

After low colo-rectal or colo-anal anastomosis there is in 25% a degree of urgency and increased bowel movements. In order to improve the reservoir continence the construction of a J-shaped colonic pouch seems reasonable. We have operated 5 patients with the new technique and worked up our preliminary results in connection with a literature overview. Increased bowel movements and urgency are reduced postoperatively but some patients report pouch evacuation problems, using enemas or suppositories to empty their reservoirs. To estimate the value of this new technique innovative endpoints as overall well-being and quality of life might be more important than conventional endpoints measuring only functional results.

Conventional versus laparoscopic cholecystectomy and the randomized controlled trial. Cholecystectomy Study Group.

We considered using a randomized trial to assess the value of laparoscopic cholecystectomy in the treatment of symptomatic gallstones. The pros and cons for the timing of such a trial were in favour of not beginning the trial until surgeons learned to use the new procedure safely and effectively, and until key endpoints and outcome indices could be identified and assessed using valid measures. Instead an observational study was implemented to monitor the learning curve of surgeons as they mastered the laparoscopic equipment and procedures, and to assess the responses of the patients to the procedure. In the first 100 patients, the procedure proved to be as safe and feasible to use as conventional surgery, and there were strong benefits in terms of quicker recovery of the patients with less pain, discomfort, and a reduced length of hospital stay. The responses of the surgeons and the patients to the new procedure now place ethical constraints on the planning of a randomized controlled trial. Currently, comprehensive surveillance and monitoring of laparoscopic cholecystectomy is the only realistic method with which to assess the impact of this new technology in our clinic.

The European experience with laparoscopic cholecystectomy.

A retrospective survey of 7 European centers involving 20 surgeons who undertook 1,236 laparoscopic cholecystectomies was performed. The procedure was completed in 1,191 patients. Conversion to open cholecystectomy was necessary in 45 patients (3.6%) either because of technical difficulty (n = 33), the onset of complications (n = 11), or instrument failure (n = 1). There were no deaths reported, and the total postoperative complication rate was 20 of 1,203 (1.6%), with 9 being serious complications requiring laparotomy. The total incidence of bile duct damage was 4 of 1,203. The median hospital stay was 3 days (range: 1 to 27 days) and the median time to return to full activity after discharge was 11 days (range: 7 to 42 days).

[Conservative surgery--choice of procedure and strategy: invasive versus minimally invasive surgery].

From the patient's view conservative surgery means less stress and strain through therapeutic interventions. Important criteria for assessment are freedom of pain, preservation of health or quick recovery from bodily impairments as well as reestablishment of integrity and fitness. The surgeon meets the patient's expectations through a careful interview, an operation with a minimally traumatizing access, a rather reliable technique and a careful follow-up. Endoscopic surgery most likely complies with this conception. This is shown in a prospective observational study on laparoscopic cholecystectomies in 500 patients and can also be expected for future indications.

[Dyspepsia and food intolerance in symptomatic gallstone disease. Does cholecystectomy help?].

60 patients with symptomatic gallstone disease were asked about their abdominal symptoms and food intolerance. Equally a healthy control group was investigated. Preoperatively, 72% of patients with gallstones suffered from right upper quadrant pain. Additionally all patients complained of associated dyspeptic symptoms (100% vs. 8% of the control group). 51% of patients with gallstone disease vs. 15% of the control group avoided flatulent and fatty food. 4 months after cholecystectomy, 90% were painfree, 82% were free of dyspeptic symptoms and 84% were not complaining of any food intolerance. 6% developed new food intolerances. Thus cholecystectomy seems to be an effective treatment, not only for typical gallstone related symptoms, but also for associated symptoms, such as dyspepsia and food intolerance. Different therapeutic regimens have to compete with these results.

Whole gut irrigation and Prepacol laxative preparation for colonoscopy: a comparison.

Two techniques for preparation of the colon for colonoscopy were compared in a controlled trial. Fifty patients given a low residue diet and the laxative Prepacol were compared with 50 patients given whole gut irrigation. Significantly more patients suffered from vomiting (P = 0.0005), shivering (P = 0.0062) and nausea (P = 0.031) following irrigation; in two cases the procedure had to be abandoned because of profuse vomiting. Irrigation was less well tolerated by the patients (P = 0.00002) than preparation with Prepacol. On the other hand, the quality of bowel preparation was found to be better (P = 0.0005) after irrigation. On two occasions colonoscopy was not possible following Prepacol preparation because of faecal residue. Patients with a previous colorectal resection showed a similar quality of cleansing to those patients prepared with irrigation. We conclude that Prepacol is as efficient as irrigation for patients who have had a previous colorectal resection because the quality of bowel preparation is as good and the associated patient discomfort is small.

[Laparoscopic cholecystectomy--initial experiences and results].

In a prospective pilot study on 100 consecutive patients with symptomatic cholelithiasis the laparoscopic cholecystectomy shows to be a safe technic without mortality and a low complication rate (3%). The time of operation is influenced by a learning curve of the operation-team and depends on the technical equipment. The postoperative hospital stay is 3 days in median. Postoperatively the pain-intensity is low and decreased very fast. These increased the patients perioperative comfort.
