[Value of celioscopy in non-traumatic acute abdomen].

The diagnostic and therapeutic value of laparoscopy in emergency was studied in 314 patients presenting with non-traumatic acute abdomen. Laparoscopy gave a correct and complete diagnosis of the underlying disease in 92% (290/314) of cases. An erroneous preoperative diagnosis was corrected by laparoscopy in 18% (58/314) of cases. This implied a change of the therapeutic strategy in 9% (27/314). Seventy five per cent (234/314) of patients were exclusively treated by laparoscopy, 22% (68/314) by laparotomy and 3% (11/314) by laparoscopically assisted surgery. Mortality was 2.5% (8/314) and morbidity 9% (29/314). In conclusion, laparoscopy is a valuable diagnostic tool for the surgeon in the context of acute abdomen and is an interesting therapeutic alternative in selected cases. However, it requires extensive experience in laparoscopic techniques.

[Cholecystectomy by celioscopy: indications and safety of the method. Apropos of a consecutive series of 300 patients].

We performed a laparoscopic cholecystectomy in 300 patients with gallstone disease complicated or not. The rate success was 97%, however involved the pathology might be. Indeed, 15% of the patients had an acute cholecystitis (10% catarrhalis, 5% empyema). Twenty-four patients with common bile duct stones had a complete endoscopic management of the biliary disease: endoscopic sphincterotomy and laparoscopic cholecystectomy. Operative mortality was absent and overall morbidity was 3.7%, exclusively minor.

Laparoscopy for management of nontraumatic acute abdomen.

The diagnostic and therapeutic influence of laparoscopy has been studied in 255 patients presenting with nontraumatic acute abdominal pain. Laparoscopy provided a correct diagnosis in 93% (236 of 255) of the cases, the others requiring a laparotomy. An erroneous preoperative diagnosis was corrected by laparoscopy in 50 patients (20%), which called for a change of treatment in 25 patients (10%). Seventy-three percent (186 of 255) of acute abdominal conditions were treated exclusively by laparoscopy, 23% (58 of 255) by conventional surgery, and 4% (11 of 255) by laparoscopically assisted surgery. Mortality was 2% (5 of 247) and morbidity 11% (28 of 247). We conclude that laparoscopy is a valuable tool for the general surgeon facing a patient with an acute abdomen.

A glomic tumour of the stomach treated by laparoscopy.

Glomic tumours are rare tumours usually found on the fingertips, particularly the nail-beds, but they can occur anywhere in the body. The first gastric glomic tumour was identified in 1942 and reported with two other cases in 1951 by Key et al. At present, 100 cases of glomic tumour of the stomach have been reported in the literature. We report a case of benign gastric glomic tumour treated by laparoscopic surgery. This type of tumour is most frequently benign but cases of malignity have been described. The preoperative assessment is important.

Biliary complications of large Echinococcus granulosus cysts: report of 2 cases and review of the literature.

Hydatid cysts are often incidentally found and remain clinically silent. However complications can occur. We present 2 patients who developed biliary complications due to a large hydatid cyst. In the first patient compression on the intrahepatic bile ducts and cystic duct by the cyst, caused cholangitis and cholecystitis. Moreover the cyst had ruptured into the right intrahepatic bile ducts. A sphincterotomy was performed with extraction of hydatid sand. A pericystectomy was necessary because of infectious deterioration of the patient. Albendazole was continued for 8 weeks after surgery. The second case presented with jaundice and weight-loss since 1 month. A large hydatid cyst caused compression on the bile duct bifurcation with proximal bile duct dilatation. A cystectomy was performed 2 weeks after albendazole therapy initiation, which was continued for 8 weeks after surgery. Follow-up of both surgical interventions was unremarkable. Although Echinococcus granulosus in not prevalent in Belgium, we must be aware of this pathology in patients coming from high endemic regions.

Laparoscopic approach in acute small bowel obstruction. A review of 68 patients.

BACKGROUND/AIMS: Laparoscopic management of acute small bowel obstruction has potential advantages over classical laparotomy. The aims of this study were to assess the feasibility and the safety of this technique, as well as to find any predictive success factors. METHODOLOGY: A laparoscopic approach was undertaken in 68 out of 150 patients admitted between 1991 and 1997 for acute small bowel obstruction. RESULTS: The cause of obstruction was bands or adhesions in 80% of the patients. A correct laparoscopic diagnosis was established in 66% of the cases. A laparoscopic treatment was performed successfully in 31 patients (46%), and was assisted by minilaparotomy in 4 patients (6%), and by open herniorraphy in 2 patients (3%). Thirty-one patients (46%) needed a conversion to laparotomy. There were 6 bowel injuries (9%), all recognized during laparoscopy. There were 2 deaths in converted patients and 2 early reoperations for persisting ileus in patients treated by laparoscopy alone or by assisted laparoscopy. CONCLUSION: Acute small bowel obstruction can be treated by laparoscopy alone, or assisted by minilaparotomy or open herniorraphy with advantages for the patient and few complications despite a high rate of conversion. There were no pre-operative predictive factors for successful laparoscopy, except for an isolated previous scar from an appendectomy. Pre-operative predictive success factors were parietal intestinal adhesions, as the only cause of obstruction. Multiple adhesions will mostly require conversion to laparotomy.
