Biliary pleural fistula as a complication of radiofrequency ablation for liver metastasis.

Radiofrequency ablation (RFA) recently emerged as an efficient and safe local ablative method to treat unresecable liver tumours. Currently however, the full spectrum of potential complications of RFA remains undetermined. We report a case of severe biliary complication, associating main bile duct stricture and biliary pleural fistula, arising after extensive RFA for unresectable liver metastasis of central location. Treatment consisted of external drainage of the pleural effusion and internal endoscopic drainage via a biliary stenting. This description of a life-threatening complication emphazises the need to better knowledge of the contraindications of RFA, particularly for the treatment of large tumours at proximity of main bile ducts.

Laparoscopic gastric reduction surgery. Preliminary results of a randomized, prospective trial of laparoscopic vs open vertical banded gastroplasty.

BACKGROUND: The purpose of the current study was to present the preliminary results of a randomized prospective trial comparing laparoscopic and open vertical banded gastroplasty (Mason's procedure). METHODS: From April 1995 to April 1996, 68 patients (9 men and 59 women, mean age, 36 years; ranges, 17-60 years) affected from morbid obesity (mean body weight, 123 kg; range, 89-188 kg; mean body mass index (BMI), 43 kg/m2; range, 37-66 kg/m2) were enrolled in a prospective trial and randomly assigned to a laparoscopic (group A) or open (group B) Mason's gastroplasty. There was no statistically significant difference between the two groups in terms of patient epidemiologic data. The significance level among the data was assessed by means of Fisher's exact test. RESULTS: The success of laparoscopic gastroplasty was 88.2% (30/34). The intervention was significantly longer in the laparoscopic group (150 min vs. 60 min; p = 0.001). No mortality was recorded in the overall population. Intraoperative complications included only one case of gastric bleeding in group A (2.9% vs. 0%; p value not significant [NS]). Early major complications ranged as high as 6.6% and 7.8%, respectively, in groups A and B (p = NS), and included one case of peritonitis and one case of pneumonia in group A, and two cases of peritonitis and one pulmonary embolism in group B. Early minor postoperative complications consisted of wound infections only, observed in one group A patient (3.3%) and four group B patients (10. 8%, p = 0.04). At longer follow-up, incisional hernias occurred in 15.8% (6/38) of patients surgically treated with a conventional approach compared with none among those successfully surgically treated with laparoscopic access (p = 0.04). No statistically significant difference was observed between the two groups regarding the efficacy of the procedure, in terms of decrease in percentage of excess body weight, mean body weight, or mean BMI. CONCLUSIONS: The preliminary results of current study show that the laparoscopic Mason procedure is a time-consuming and technically demanding operation, as effective as its traditional counterpart, but carrying a statistically significant decrease in the incidence of wound infections and incisional hernias.

[Case report of an adrenal hemorrhagic pseudocyst. Literature review].

Cysts and pseudocysts of the adrenal gland are usually discovered fortuitously, either on clinical examination or on the occasion of a radiological check-up for a non specific symptomatology. Their diagnosis rests on several examinations such as intravenous pyelography, ultrasounds, computerized tomography or arteriography. The final diagnosis relies on the histological examination of removed material. Surgery is systematically advocated as the actual nature of the tumor cannot be established preoperatively.

[Esophageal perforation caused by a foreign body. Apropos of a case report].

This report describes an esophageal foreign body perforation treated with T-tube drainage. The clinical diagnosis was delayed erroneously and by the absence of extravasation of water--soluble contrast material. The diagnosis has finally been made by a fiberoptic oesophagogastroscopy and a mediastinal computed tomography. As the external drainage by pleural drainage was inefficient, the authors opted for a surgical treatment, and the perforation was closed on a T-tube. Considering this case as well as the review of the different reports, urgent surgery seems to be only recommended for large esophageal perforations and for small non-cervical perforations where external drainage is inefficient.

Endoscopic management of a post-traumatic biliary fistula.

A number of techniques of surgical endoscopy have been used in the management of a post-traumatic biliary fistula. The endoscopic sphincterotomy with placement of a perfused nasobiliary catheter, followed by the insertion of a biliary stent allowed the fistula to dry out. A secondary stricture of the left hepatic duct was treated by endoscopic internal drainage after the insertion of a transhepatic guidewire by an epigastric route. This kind of combined transhepatic and endoscopic procedure is useful in some difficult cases.

Mesenteric vein thrombosis: early CT and US diagnosis and conservative management.

We report a case of isolated superior mesenteric vein thrombosis with acute ischemic bowel disease, diagnosed early by a screening ultrasound scan of the upper abdomen and definitively assessed by computed tomography and angiography. This report stresses the contribution of cross-sectional techniques in the early diagnosis and management of venous occlusive disease of the small bowel.

[Surgery of acute cholecystitis in patients 80 years of age or older].

In 17 Belgian surgical centers, 324 operations have been performed for acute cholecystitis in patients 80 years of age or older. In this group of patients: 1. The incidence of acute cholecystitis is hardly higher in women than in men. 2. The patients were operated within 24 hours of admission in 38% of cases. The main bile duct was surgically explored in 1/3 of patients. Cholecystostomy or simple drainage were used in 1/10 of cases only. 3. Operative mortality was 19%. It was higher for patients operated as emergencies than for delayed operations and higher also when the cholecystectomy was associated with an exploration of the bile duct. The ideal treatment for such patients should thus be a cholecystectomy with an endoscopic sphincterotomy.

Gallium-67 citrate as an aid to the diagnosis of infection in hip surgery.

We have evaluated the use of Gallium-67 scans as an aid to the diagnosis of infection around the hip joint after operation. We performed 12 gallium-67 scintiscans on six patients with diaphyseal fractures of the femur or tibia reduced by external fixation, and 65 scintiscans on 60 hips after operation, which included 22 Moore's prosthesis, 31 total replacements, three nail-plates and four revisions of total replacements. We also scanned the healing surgical wounds in a further 11 patients. Simple fractures or osteotomies did not lead to abnormal uptake of 67Ga. Although some uptake in the scar was encountered the surgical wound did not complicate the interpretation of the scan. When assessing infection in the hip operations the rate of true-positive was 11/11, or 100%. The false-positive rate could not be assessed until after at least one year's follow-up. It was certainly less than 14% immediately after operation and less than 6% when the scan was performed three months after operation. Four patients were found to have a loose prosthesis but had a normal scintiscan, as had three patients presenting with post-operative pain. It appears that 67Ga is clinically an efficient means for early detection of infection about the operated hip, and is useful in the differential diagnosis of a painful hip after surgery.
