Social acceptability of treatments for adolescent idiopathic scoliosis: a cross-sectional study

BACKGROUND: There are no data on social acceptability of scoliosis. Aim. To elicit evidence-based opinions on therapeutic strategies for adolescent idiopathic scoliosis in a sample of families with not affected children, so to understand the social perception of this issue. METHODS: Design. Cross-sectional study. Setting. Secondary schools in 4 northern Italian regions. Participants. Parents of children in the age group at risk of and not affected by scoliosis (Pre-test group = 100, Study group = 3,162). Interventions. Questionnaire: five specific and evidence-based questions regarding scoliosis treatment options and a socio-demographic section. Methodology. "Role-playing" in which it was required to normal people to answer what they would have chosen if they had been in the situation proposed. Main outcome measures. Perception of acceptability of treatments for adolescent idiopathic scoliosis in the general population (social acceptability) RESULTS: The families support the use of screening (94.8%) at school, immediate bracing (76.4%) for scoliosis with a 60% risk of progression, but also therapeutic exercises (86.9%) in cases with a 25% risk of progression. CONCLUSION: There is a growing tendency to consider not only the efficacy, effectiveness and efficiency of treatments, but also their acceptability. This patient-centred aspect is especially more important in areas (like adolescent idiopathic scoliosis) in which there is some evidence on the efficacy of treatments, but not strong and definitive (RCTs). Adolescent idiopathic scoliosis treatments should thus be carefully considered also in the light of their social acceptability

Hepatic Artery Kinking during Liver Transplantation Survey and Prospective Intraoperative Flow Measurement

Hepatic artery thrombosis (HAT) represents the most common vascular complication occurring after liver transplantation (LT). Herein, we report the results of a prospective study of hepatic artery flow (HAF) measurement during abdominal wall closure after LT along with the results of an international survey of procedures adopted, in order to avoid the arterial kinking (AK) in case of long artery. Sixty-four surgeons were asked regarding the different procedures used to avoid AK in the presence of long artery. We prospectively assessed the HAF during three phases of LT in 26 consecutive LT performed in patients with a long HA: after completion of the biliary anastomosis (M0), and partial abdominal wall closure with (M1w) or without (M1w/o) hepatic artery anti-kinking method (HAAK). Sixty (93.7 %) surgeons replied to the survey: 44 (73.3 %) surgeons cut the artery as short as possible, of whom 38 (86.3 %) interposed an oxidized polymer or the omentum, and six (13.7 %) used other systems. Fourteen (23.3 %) surgeons did not use any interposition methods. The remaining two (3.3 %) surgeons left a long artery without HAAK. In our cohort we obtained the following HAF measures: M0 152 mL/min (89-205), M1 without HAAK 114 (66-168) and M1 with HAAK procedure 158 (91-219) (p = 0.002). Our survey confirms that no consensus is currently available regarding the most effective method for avoiding AK. Kinking occurs most probably when the liver is released in its final position. The utilization of an interposition method could ensure the maintenance of a correct HAF

Double Arterial Anastomosis in Liver Transplantation: Is Two Better than One?

Arterial revascularization during liver transplantation is normally achieved by anastomosing the graft hepatic artery to the largest artery available at the recipient pedicle-either the common hepatic artery (CHA) or an accessory right hepatic artery (RHA) originating from the superior mesenteric artery (SMA). When a small caliber RHA is present, the artery is ligated and a single anastomosis with the CHA is performed. In the absence of a vascular reconstruction of the graft, the gastroduodenal artery is usually ligated as well. In this article, we describe a new type of arterial anastomosis in the case of a small accessory RHA and/or severe graft hepatic artery atherosclerosis that is commonly seen in elderly donors. To our knowledge, these are the first cases reported in the literature. This technique can be easily performed without increasing the arterial revascularization time or increasing the risk of complications associated with arteriosclerotic arteries. A 12-month follow-up revealed excellent function of the liver grafts

Reversed Saphenous Bypass for Hepatic Artery Pseudoaneurysm After Liver Transplantation

Background: Hepatic artery pseudoaneurysm (HAP) is found in 1-2% of liver transplantation (LT) patients. The mortality associated with pseudoaneurysm formation after orthotopic LT is reported to be as high as 75%. Because of the rarity of complications, particularly when considered individually, much of the direction for the management of complications is anecdotal. This article discusses the presentation, etiology, types, treatment indications, and vascular procedures used to manage complications with LT. Methods: Between January 2004 and December 2011, 464 LTs were performed at our institution. Of these, 9 (1.9%) consecutive patients underwent surgical treatment of HAP (8 men and 1 woman; median age, 58.4 years [range, 46-67 years]). Four patients underwent transarterial chemoembolization before LT for hepatocellular carcinoma. In all cases, revascularization with a reversed autologous saphenous vein bypass was performed. Results: Four patients had ruptured pseudoaneurysms, and the others were diagnosed as having asymptomatic pseudoaneurysms during the follow-up period. The median delay between LT and the diagnosis of HAP was 39.6 days (range, 22-92 days). All were anatomically extrahepatic. The median diameter was 15.3 mm (range, 9-30 mm). Four patients had a T-tube. In 6 cases, biliary leakage was associated with the LT and, in the remaining 3, mycosis was recorded. After surgery, 1 patient underwent retransplantation because of ischemic cholangitis. Five years later, 5 patients had normal arterial anatomy, and the other 3 patients had stenosis that was successfully treated by stents. All of the patients had normal liver function at follow-up. One patient died 16 months later because of a heart attack. Conclusions: HAP with massive intraperitoneal bleeding is a rare but serious life-threatening complication when it occurs after LT. The majority of HAP cases are associated with bile leakage and mycosis; therefore, surgery must be the treatment of choice. Our conclusions support surgical revascularization with reversed saphenous grafts as a feasible and efficient treatment in cases of HAP

Rubber transcystic drainage reduces the post-removal biliary complications in liver transplantation: a matched case-control study

Bile duct (BD) complications continue to be the "Achilles' heel" of liver transplantation, and the utilization of bile duct drainage is still on debate. We describe the results of a less invasive rubber trancystic biliary drainage (TBD) compared to a standard silicone T-tube (TT). The transplanted patients (n = 248), over a period of 5 years with a TBD (n = 20), were matched 1:2 with control patients with a TT (n = 40). Primary end points were the overall incidence of BD complications and graft and patient survival. Secondary end points included the complications after the drainage removal. Although the bile duct leakage rates were not significantly different between both groups, the TT group had a significantly higher rate of overall 1-year BD stenosis (40 versus 10 %) (p = 0.036). Three-year patient/graft survival rates were 83.2/80.1 and 84.4/84.4 % for the TT and TBD groups, respectively. The postoperative BD complications, after drainage removal (peritonitis and stenosis), were significantly reduced (p = 0.011) with the use of a TBD. The use of rubber TBD in liver transplant recipients does not increase the number of BD complications compared to the T-tube. Furthermore, less BD anastomotic stenosis and post-removal complications were observed in the TBD group compared to the TT group
