In acute abdominal syndromes when a surgical exploration is required by the presence of peritoneal symptoms, laparoscopy allows to recognize the lesions and to perform simultaneously the appropriate treatment in most cases. When the surgical indication is doubtful, mainly in case of acute appendicitis, sonography or scanography may confirm the diagnosis. In case of persisting doubt, diagnostic laparoscopy is justified and laparoscopic appendicectomy seems to be the best method when another pathology is not detected by laparoscopy. In abdominal wounds, laparoscopy is useful to confirm their intraperitoneal penetration, mainly in gunshot wounds, and to recognize a diaphragmatic wound which is often isolated and unknown. Laparoscopy often fails to detect all abdominal injuries. In blunt abdominal traumas, laparoscopy is not recommended at the first step. In conclusion, laparoscopy with diagnostic intent only is rarely indicated in abdominal emergencies and its use is not worth being extended. Diagnostic value of laparoscopy is closely linked to its therapeutic interest. Laparoscopy with both diagnostic and therapeutic intent has to be developed in most abdominal emergencies.

Study aim

The aim of this retrospective survey was to evaluate the results of laparoscopic treatment in perforated peptic ulcer.

Patients and methods

From 1989 to 1998, 84 patients were operated on for perforated ulcer. Sixty nine patients, operated on with videolaparoscopy, were included in this study: 53 men and 12 women with a mean age of 45 ± 16 years (19–85). Nine had a history of peptic ulcer disease and 12 received anti-inflammatory drugs. Perforation occurred in the duodenum (60 patients) and in the stomach (five patients). Laparoscopic treatment included peritoneal lavage and either a simple duodenal closure (51 patients), a closure with a highly selective vagotomy (one patient), an epiplooplasty (eight patients), or an excision-closure for the gastric ulcers (five patients). Drainage was associated in 38 patients (58%).

Results

A conversion into laparotomy was necessary in six patients. Among the 59 patients treated with laparoscopy, 56 were only managed laparoscopically, three had exploration and peritoneal lavage through laparoscopy, and underwent suture of the perforation through minilaparotomy. Mean operative time was 105 ± 40 minutes (30–240). Mean postoperative hospital stay was 8.2 ± 4 days. Reoperation was performed in three patients for leakage (n = 2) and gall bladder perforation (n = 1). Complications were medically treated in three patients. There was no in-hospital mortality.

Conclusion

Laparoscopic management in perforated peptic ulcer is successful in 90% of the patients. Results are good. There was no postoperative death in this series.

Study aim

The aim of this retrospective study was to report a series of 28 patients with adenocarcinoma (ADK) arising in Barret's esophagus (BE), treated by esophagectomy.

Patients and methods

From 1992 to 1998, 28 patients were operated on for ADK in BE. There were 27 men and one woman (mean age: 65 years) classified as ASA I (n = 2), ASA II (n = 15) and ASA III (n = 11). Eighteen patients had a long story of gastro-esophageal reflux disease which required surgical repair in five of them. Dysphagia was the main symptom (n = 19). Surgical procedures included 15 Ivor Lewis operations, nine esophagectomies without thoracotomy and four esophagogastrectomles by the left thoracic approach.

Results

Pathological examination of the specimens showed an EBO with adenocarcinoma (n = 27) and a high grade dysplasia (n = 1). Among five patients with a previously known BE, three under endoscopic surveillance had high grade dysplasia (n = 1) and limited T1 tumor (n = 2), while the other two patients without surveillance developed an invasive tumor (T3N1). There were three postoperative deaths (mortality rate: 10%), all arising from pulmonary failure. Median survival was 16.6 months. All patients resumed a normal diet. The actuarial survival rates were 63%, 42% and 15.2% respectively at 1, 2 and 4 years. A multivariate analysis could identify 3 prognostic factors: ASA score previously known BE under surveillance, lenght of BE.

Conclusion

Adenocarcinoma arising in BE is very often diagnosed too late. Patients with high risk BE require an endoscopic survey. High grade dysplasia detected in two successive examinations by two different pathologists may require prophylactic esophagectomy, but local endoscopic management presently under evaluation could be efficient in the future.

Aim of the study

To describe a technique of percutaneous CT guided catheter drainage of infected pancreatic necrosis and to report the results of this technique compared with those of the conventional surgical treatment and of other percutaneous drainage series.

Patients and methods

Between 1992 and 1997, the series included 32 patients who had a severe acute necrotizing pancreatitis with a mean Ranson score of 4.6, scored into grade D (n = 10), and grade E (n = 22), according to the Balthazar radiological staging. Modified Van Sonnenberg 24 F double lumen catheters were used for continuous irrigation and aspiration.

Results

Forty-nine drains were inserted for 41 infected necroses and eight abscesses. Among the 32 patients, the proof of infected necrosis was obtained in 26 patients by fine needle aspiration and culture (enteroccus, staphy-lococcus, pseudomonas). The average delay of catheter insertion was 23 days after onset of pancreatitis; the mean duration of drainage was 43 days, and an average of three catheters per patient was required. Five patients (15%) died, and among the survivors, 16 (59%) presented 21 complications including 14 enterocutaneous or pancreatic fistulas. A subsequent surgical 11procedure including two necrosectomies was necessary in six patients.

Conclusion

This study demonstrates that percutaneous drainage of infected pancreatic necrosis with a 15% mortality and 70% success rate, represents an interesting alternative to conventional surgery.
