RESUMO

Abdominal compartment syndrome is a potentially life-threatening condition seen in critically ill patients, and most often caused by acute pancreatitis, postoperative abdominal vascular thrombosis or mesenteric ischemia. A decompressive laparotomy is sometimes required, often resulting in hernias, and subsequent definitive wall closure is challenging. AIM: This study aims to describe short term results after a modified Chevrel technique for midline laparotomies in patients witch abdominal hypertension. MATERIALS AND METHODS: We performed a modified Chevrel as an abdominal closure technique in 9 patients between January 2016 and January 2022. All patients presented varying degrees of abdominal hypertension. RESULTS: Nine patients were treated with new technique (6 male and 3 female), all of whom had conditions that precluded unfolding the contralateral side as a means for closure. The reasons for this were diverse, including presence of ileostomies, intraabdominal drainages, Kher tubes or an inverted T scar from previous transplant. The use of mesh was initially dismissed in 8 of the patients (88,9%) because they required subsequent abdominal surgeries or active infection. None of the patients developed a hernia, although two died 6 months after the procedure. Only one patient developed bulging. A decrease in intrabdominal pressure was achieved in all patients. CONCLUSION: The modified Chevrel technique can be used as a closure option for midline laparotomies in cases where the entire abdominal wall cannot be used.

RESUMO

Abdominal wall transplant is developed in the context of intestinal and multivisceral transplant, in which it is often impossible to perform a primary wall closure. Despite the fact that abdominal wall closure is not as consequential in liver transplant, there are circumstances in which it might determine the success of the liver graft, especially in situations that compromise the abdominal cavity and facilitate an abdominal compartment syndrome. CASE 1: A 14-year-old girl suffering from cryptogenic cirrhosis with severe portal hypertension that causes ascites and severe malnutrition. Uneventful liver transplant, with a graft procured from a 14-year-old donor. At the time of wall closure it was decided to implant a nonvascularized fascia graft to supplement the right side of the transverse incision, with a 17 x 7 cm defect. This required reintervention after 4 months for biliary stricture. At that point, the wall graft was almost completely integrated into the native tissue. CASE 2: A 63-year-old man, transplanted for hepatitis C virus+ hepatocellular carcinoma+ nonocclusive portal thrombosis. Thirty-six hours after transplant the patient developed portal thrombosis. Thrombectomy and closure with biological mesh were performed. After 24 hours he was reoperated on for abdominal compartment syndrome and temporary closure with a Bogotá bag. Six days later he underwent omentectomy, intestinal decompression, and left components separation, identifying a 25 x 20 cm defect. For definitive closure, a nonvascularized fascia graft procured from a different donor was used, accomplishing a reduction in intra-abdominal pressure. Nonvascularized fascia transplantation is an interesting alternative in liver transplant recipients with abdominal wall closure difficulties.

RESUMO

BACKGROUND: The prevalence of obesity has increased dramatically, even in the population awaiting a liver transplantation. Despite their associated complications, we cannot consider morbid obesity any longer as an absolute contraindication to liver transplantation. Dietary approaches alone are usually completely ineffective. Bariatric surgery is the gold-standard treatment for morbid obesity and can be performed before, during, or after transplantation. MATERIALS AND METHODS: At our Liver Transplantation Unit, a single surgeon performed a sleeve gastrectomy in 8 patients with liver cirrhosis due to nonalcoholic steatohepatitis, alcohol, or HCV. The Child score was A in 6 patients and B in the remaining 2 patients. Two of our patients had portal hypertension with mild esophageal varices. The procedure was performed laparoscopically in 7 cases (87.5%); in the other case, it was performed by open approach due to portal hypertension and according to patient preferences. RESULTS: Patients showed no postoperative morbidity or mortality. The mean postoperative body mass index of our patients was 37.4, 33.3, and 30.3 kg/m2 at 3, 6, and 12 months after surgery, respectively. The mean percentage excess weight loss of our patients was 42.9%, 62.2%, and 76.3% at 3, 6, and 12 months. Two of the patients have already undergone a successful liver transplant. CONCLUSION: Bariatric surgery in selected patients with compensated cirrhosis and without significative portal hypertension is reasonable. There are not clear guidelines on the use of bariatric surgery in patients with cirrhosis. In our experience, the sleeve gastrectomy is safe and effective in the treatment of patients with compensated cirrhosis; in a short time, the sleeve gastrectomy can improve candidacy in morbidly obese patients awaiting transplantation.
