[Does laparoscopy reduce the incidence of useless appendectomies?].

The aim of this retrospective study is to evaluate the impact of laparoscopic appendicectomy on the incidence of histologically normal appendices. Between 1987 and 1997, 1220 consecutives patients--with an average age of 23.5 years (17-73) and including 841 women (69%)--underwent appendicectomy due to the presence of at least one of the following 3 criteria: right iliac fossa guarding, fever greater than 38 degrees C and hyperleucocytosis greater than 10,000. Patients were divided into two group.: First group with 930 patients were operated by laparotomy and the other group of 355 patients underwent laparoscopic exploration with appendicectomy when macroscopic abnormalities were observed (290 cases). In all cases, the appendices were examined under blind conditions and classified as normal or pathological, and were subsequently classified according to the nature and the severity of the lesions. In group I (laparotomy), the incidence of histologically normal appendices was 25.1%. In group II (laparoscopic), this incidence was only 8.2%. The difference was significant (p = 0.015). In 65 cases (18.3%), a macroscopically normal appendix was left in place: in 55 cases the symptoms were due to another identified cause, however, in 10 cases no cause was found. This study suggests that laparoscopy significantly reduces the number of histologically normal appendices because an other cause is identified more easily provided macroscopically normal appendices are not removed with a small proportion (5-10%) cases of early appendicitis with only mucosal involvement. In the absence of other causes for the symptoms, a three-day course of antibiotics can be tried in order to treat possible mucosal lesions. This approach reduces costs without having any adverse consequences on outcome.

[Peroperative investigation of the common bile duct during laparoscopic cholecystectomy. Laparoscopic ultrasonography versus cholangiography. A prospective study of 150 cases].

From November 1994 to March 1996, 150 patients treated by laparoscopic cholecystectomy were included in a prospective study, in order to compare intraoperative cholangiography and laparoscopic ultrasound. The biliary tree was successively explored by the two methods in the systematic detection of common bile duct stones. The feasibility of laparoscopic ultrasound was 100 per cent. Cholangiography was performed in only 125 cases (83 per cent). The duration of the laparoscopic ultrasound exam was significantly shorter (11.6 vs 17.6 minutes, p = 0.0001). In this study, common bile duct stones were found in 14 cases (9 per cent). The detection rates with laparoscopic ultrasound and intraoperative cholangiography were similar. For laparoscopic ultrasound, sensitivity was 80 per cent and specificity was 99 per cent, versus 78 per cent and 97 per cent for cholangiography, respectively. The combination of the 2 examinations had a 100 per cent sensitivity and specificity. Laparoscopic ultrasound failed to recognize the intrapancreatic part of the bile duct (25 cases: 17 per cent), did not show anatomical abnormalities detected by cholangiography, but detected unsuspected digestive lesions. Laparoscopic ultrasound is safe repeatable, and non invasive, but a learning curve is necessary to increase this efficacy. Comparison of cost must be evaluated.

[Laparoscopic correction of recurrent gastro-esophageal reflux following laparoscopic fundoplication (4 cases)].

A series of 98 laparoscopic fundoplications, included 7 cases (7.1%) of recurrent gastro-oesophageal reflux. Six of these cases occurred within 12 months of surgery. Four were successfully treated by a second laparoscopic procedure. The mean interval between the initial and corrective operations was 10 months. Factors related to failure were: technical errors, operative inexperience, obesity and the size of the hiatus hernia (when crural closure was not performed). Laparoscopic re-operation to was relatively easy and without mortality but had an increased risk of pleural effusions. The mean length of hospital stay for re-operations was identical to that of initial operations (4 days). No further recurrences were noted after a mean follow-up of one year (280-475 days). We conclude that early failures following laparoscopic fundoplication can be effectively dealt with laparoscopic surgery.

[Port-site metastases. A prospective study of 131 cases].

UNLABELLED: Laparoscopic staging and laparoscopic treatment of gastrointestinal malignancy is still controversial because some studies report port-site metastases. BACKGROUND: The aim of the study is to determine in 131 patients, with prospective follow-up, after laparoscopic staging or laparoscopic treatment the incidence of port-site metastases. METHODS: 131 patients, with gastro intestinal malignancy, proved or with peritoneal carcinomatis or liver metastases, were included. In 57 cases only laparoscopic staging is performed in 49 cases laparotomic treatment is performed a after laparoscopic staging; in 57 cases (43.5 per cent) tumor invaded serosa. RESULTS: The median follow-up was 17.7 months (3 to 62 months). 502 port-sites were controlled. One patient (0.7%) has presented one port site metastasis 3 months after right colectomy for carcinoma with local carcinomatis. CONCLUSION: The study affirm that port-site metastases are rare. They are favorised by serosa invasion. The low rate indulge in laparoscopic staging to recognize occults lesions which are not detected by conventionals examinations in 44.2 per cent in this study.

[Laparoscopic resection of gastric conjunctive tumor. Apropos of 2 cases].

We report two cases of benign gastric tumours which were resected laparoscopically. The lesions were diagnosed pre-operatively by upper endoscopy and endoscopic ultrasound. Excisions were complete with satisfactory resection margins. The post-operative courses were uncomplicated: the length of hospital stay for both patients was 6 days. This technique would appear to be a promising alternative to laparotomy for selected cases.

[Peroperative contamination of the peritoneal cavity with micro-foreign bodies].

This prospective study examined the presence of foreign bodies in postoperative adhesion specimens and parietal peritoneum removed in a given patient at the same operative site. Fifty-two consecutive patients were enrolled. A significantly larger number of foreign bodies were observed in adhesion specimens than in peritoneum specimens. Inflammatory processes were also found to develop preferentially on the perioneum. In man, foreign bodies participate in the mechanism of development of postoperative intraperitoneal adhesions.

[Laparoscopic colectomy. Techniques and indications].

Standard techniques for laparoscopic colectomy are currently well defined and are described here. Details are provided concerning facilities, equipment, and operative procedures for resection of the rectum, the left and right colons and total colectomy. Questions of indications are carefully addressed. Laparoscopic colectomy is an excellent indication for benign inflammatory as well as tumoral diseases. Inversely, there is some discussion concerning indications in colorectal cancer due to the risk of trocar tract metastasis. Based on data in the literature, the results of laparoscopic colectomy are analyzed together with the advantages of this technique in terms of mortality, morbidity, and hospitalization stay in comparison with conventional surgery.

[Strangulated obturator hernia. Preoperative diagnosis].

Strangled obturator hernia is uncommon; 600 cases have been reported in the literature since 1994. The diagnosis of strangled obturator hernia is rarely made preoperatively. We report a case of preoperative diagnosis which would suggest that laparoscopic surgery would be an interesting technique allowing both diagnosis and complete exploration of the abdominal cavity providing prognosis information for assessment of the lesion and treatment.

[Is there an age limit for laparoscopic cholecystectomy? Apropos of 61 patients over 85 years of age].

Bilary surgery in the elderly is associated with high morbidity and mortality. The aim of this prospective study was to determine benefits of laparoscopic cholecystectomy in patients over 85 years. From August 1990 to January 1996, 61 patients (50 women, 11 men) aged over 85 years had laparoscopic cholecystectomy. Thirty seven (60.6%) were at high surgical risk (ASA III). In more than 40% of cases complications were present (acute cholecystitis, gallbladder empyema). Nine patients (14.7%) had choledocholithiasis. Ten (16.3%) conversions were necessary, in 5 cases for choledocholithiasis. Overall morbidity was 9.8%: 2 bibary leaks, 1 pneumonia, 1 urinary injection and 1 lymphangitis. There was no mortality. With excellent pre-operative risk evaluation, laparoscopic cholecystectomy is better than laparotomy cholecystectomy. Laparoscopic cholecystectomy has a low morbidity in the elderly and it allows curative treatment of gallstones complicated or not.

Giant cavernous hepatic hemangiomas in adults: enucleation under selective blood inflow control.

Among hepatic hemangiomas (the most common solid hepatic tumor in adults), "giant hemangiomas" are those defined by a diameter greater than 4 cm. The natural history of such lesions is unclear, and many surgical procedures have been described. In five women and one man (mean age 49), we successfully used enucleation of the tumor under blood inflow control. This technique was made possible by a cleavage plane between the hepatic parenchyma and the hemangioma. This straightforward and safe procedure required a low rate of transfusion (mean 200 mL/patient) and spared a maximum amount of hepatic tissue.

[Colonic esophagoplasty for benign lesions].

68 patients underwent oesophageal replacement for benign disease: atresia (12), reflux oesophagitis (16), caustic stenosis (37), internal fistula (3). The transplant was the ileocolon (27), the transverse (5) or left colon (36). It was substernal (55) or posterior mediastinal (13). A by-pass was performed without oesophagectomy (51) or an interposition accompanied oesophagectomy (17). The superior anastomosis was cervical (52) or thoracic (16). The inferior anastomosis was on the stomach (46), duodenum (10) or jejunum (12). Hospital mortality was 8.8%, morbidity was 57.3%. Among the 62 survivors, 18 had another operation. At the end of the survey, 68% had near normal function.
