Surgical treatment of adult primary hepatic sarcoma.

BACKGROUND: Primary sarcomas of the liver are extremely rare in adults. Optimal therapeutic approaches remain unclear. METHODS: Twenty consecutive adult patients who had surgical treatment for primary hepatic sarcomas were reviewed. Patient age ranged from 23 to 80 years. Other than one patient with primary hepatic angiosarcoma who had a history of thorium dioxide colloid (Thorotrast) exposure 23 years before diagnosis, no predisposing causes were apparent. Nineteen patients had hepatic resection and one patient had an orthotopic liver transplant. No patient received neoadjuvant chemotherapy or radiotherapy but radiotherapy was delivered intraoperatively in one patient. RESULTS: Leiomyosarcoma was the most common histological type of sarcoma diagnosed (five of 20 patients), followed by malignant solitary fibrous tumour (four) and epithelioid haemangioendothelioma (three). Fourteen tumours were high-grade sarcomas and six were low grade malignancies. Thirteen patients developed a recurrence. Distant metastases (ten patients) and intrahepatic recurrence (six) were the predominant sites of initial treatment failure. Six patients received salvage chemotherapy. Histological grade was the only factor significantly associated with overall patient survival (P= 0.03). With complete resection, patients with high-grade tumours had a 5-year survival rate of 18 (95 per cent confidence interval 5-62) per cent compared with 80 (52-100) per cent for patients with low-grade tumours. The 5-year survival rate for all 20 patients was 37 (20-60) per cent. CONCLUSION: Surgical resection is the only effective therapy for primary hepatic sarcomas at present. Better adjuvant therapy is necessary, especially for high-grade malignancies, owing to the high failure rate with operation alone.

Bariatric surgery. Surgery for weight control in patients with morbid obesity.

Morbid obesity has become a health crisis in the United States. Medical programs developed at nonoperative attempts to lose (and maintain) an adequate weight loss are largely unsuccessful. Bariatric surgery has been proven to be effective at inducing and maintaining a satisfactory weight loss to decrease weight-related comorbidity. Bariatric operations include procedures that decrease mechanically the volume capacitance of the proximal stomach (vertical banded gastroplasty, laparoscopic gastric banding) or decrease the proximal gastric capacitance and establish a partial selective malabsorption (gastric bypass and its modifications, partial biliopancreatic bypass, and duodenal switch with partial biliopancreatic bypass). These operations should induce a loss of at least 50% (or more) of excess body weight. Not all patients are candidates for these procedures, and the best results are obtained by a multidisciplinary team (including nutritionist, physician, dietitian, psychologist or psychiatrist interested in eating disorders, and surgeon).

A comparison of laparoscopic and open cholecystectomy in patients with compensated cirrhosis and symptomatic gallstone disease.

BACKGROUND: The purpose of this study was to compare the risks and benefits of performing open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) in patients with compensated cirrhosis. METHODS: Data on 50 patients who underwent cholecystectomy for the treatment of symptomatic gallstone disease between 1990 and 1997 were collected retrospectively. These patients were divided into 2 groups: Group I included 24 patients who underwent OC, and Group II included 26 patients who underwent LC. The cohorts were well-matched for age, sex, race, clinical presentation, and Child-Turcotte-Pugh (CTP) class. Twelve patients in Group I had a concomitant surgical procedure in contrast to only 2 patients in Group II. No patient in this study had CTP Class C cirrhosis. RESULTS: There was no operative mortality. Conversion to OC was necessary in 3 patients (12%) during LC because of uncontrollable liver bed bleeding in 2 of the patients and insufficient visualization of the anatomy in 1 of the patients. Mean surgical times were significantly longer in Group I when comparing patients from both groups without concomitant surgical procedures (mean +/- SD, 177 +/- 91.3 minutes vs 116.8 +/- 42.3 minutes, P = .037). No patient in Group II required any blood component replacement in contrast to 9 patients (38%) in Group I. Intraoperative bleeding remained significantly higher in Group I when comparing patients without concomitant surgical procedures (P = .043). No patients in Group II had a wound complication, compared with 2 patients (8%) in Group I. The 12 patients without concomitant surgical procedures in Group I had significantly longer hospital stays when compared with 24 patients without concomitant surgical procedures in Group II (mean +/- SD, 6.9 days +/- 3.3 [median 6] vs 2.4 days +/- 1.8 [median 2.0]); P = .001. CONCLUSIONS: Our results demonstrate that laparoscopic cholecystectomy can be performed safely in patients with CTP Class A and B cirrhosis. It offers several advantages over open cholecystectomy, including lower morbidity, shorter operative time, and reduced hospital stay with less need for transfusions.

Ten and more years after vertical banded gastroplasty as primary operation for morbid obesity.

Long-term follow-up (>10 years) after vertical banded gastroplasty (VBG) is almost nonexistent. The aim of this study was to determine long-term outcome after VBG in a group of 71 patients studied prospectively. Seventy-one consecutive patients with morbid obesity (54 women and 17 men; mean age 40 years [range 22 to 71 years]) underwent VBG from 1985 to 1989 and were followed prospectively. Follow-up was obtained in 70 (99%) of the 71 patients. Weight (mean +/- standard error of the mean) preoperatively was 138 +/- 3 kg and decreased to 108 +/- 2 kg 10 or more years postoperatively. Body mass index decreased from 49 +/-1 to 39 +/- 1. Only 14 (20%) of 70 patients lost and maintained the loss of at least half of their excess body weight with the VBG anatomy. Vomiting one or more times per week continues to occur in 21% and heartburn in 16%. Fourteen patients have undergone conversion from VBG to Roux-en-Y gastric bypass (11 patients) or other procedures (3 patients) because of a combination of inadequate weight loss in 13 patients, gastroesophageal reflux in five, and frequent vomiting in four. Only 26% of patients after VBG have maintained a weight loss of at least 50% of their excess body weight; 17% underwent bariatric reoperation with good results. Thus VBG is not an effective, durable bariatric operation.
