High incidence of venous thrombosis after surgery for abdominal aortic aneurysm
2009
Objective The incidence of venous thromboembolism (VT) after aortic abdominal aneurysm (AAA) surgery is imprecisely reported. On one hand, thromboprophylaxis has improved, on the other hand, AAA patients have become older and/or present worse comorbidities. Herein, we prospectively analyzed the incidence of VT in a continuous series of patients operated on for AAA repair and looked for predictive factors. Materials and Methods Between January 1, 2005, and December, 31, 2006, 193 consecutive patients (177 men and 16 women), mean age 73 (range, 47-93) underwent elective AAA repair, 137 open (71%) and 56 endovascular (29%), in our institution. Thromboprophylaxis consisted of thigh-length compr…
Cinical outcomes of Endurant II stent-graft for infrarenal aortic aneurysm repair: comparison of on-label versus off-label use.
2016
Purpose We aimed to compare the outcomes of the Endurant II (Medtronic) stent-graft used under instructions for use versus off-label in high-risk patients considered unfit for conventional surgery. Methods Data from patients treated with the Endurant II stent-graft between December 2012 and March 2015 were retrospectively analyzed. Sixty-four patients were included. Patients were assigned to group A if treated under instructions for use (n=34, 53%) and to group B if treated off-label (n=30, 47%). Outcome measures included perioperative mortality and morbidity, survival, freedom from reintervention, endoleak incidence, in-hospital length of stay, and mean stent-graft component used. Mean fol…
Preoperative detection of intrathoracic tumor spread of esophageal cancer: endosonography versus computed tomography.
1991
The results of endosonography and computed tomography, using an optimized CT technique, have been compared in the preoperative detection of intrathoracic tumor spread of esophageal cancer. In 22/40 patients with esophageal tumors complete passage of the ultrasonic endoscope was possible. Endosonography was superior to CT in the assessment of early stage of esophageal tumor (T1-2). Out of 9 tumors confined to the esophageal wall, 8 were classified correctly by endosonography and only 5 by computed tomography. The results in advanced T3 and T4 tumors (13 patients) were comparable following endosonography and computed tomography. Endosonography is an important means of selecting patients with …
Positron Emission Tomography for Staging Esophageal Cancer: Does It Lead to a Different Therapeutic Approach?
2003
Accurate preoperative staging is essential for the indication and selection of the appropriate surgical procedure in patients with esophageal cancer. The present prospective study was designed to determine if the preoperative use of (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) increases the accuracy of staging esophageal cancer compared with computed tomography (CT) and if it thereby leads to a different therapeutic approach. A total of 58 patients, 46 men and 12 women (mean age 61 years), with histologic proof of esophageal carcinoma underwent FDG-PET of the neck, chest, and abdomen, as well as CT of the chest and abdomen, to determine tumor stage. FDG-PET and CT data we…
Use of Intraperitoneal ePTFE Gore Dual-Mesh Plus in a Giant Incisional Hernia After Kidney Transplantation: A Case Report
2009
We evaluated the incidence of and predisposing factors for an incisional hernia after kidney transplantation. Numerous techniques have been used to repair postoperative fascial dehiscences or simple incisional hernias, but no clear treatment exists for giant hernias. Our aim was to obtain (1) a safe procedure to repair a large abdominal defect and reinforce the surrounding, fragile zones and (2) a simple, rapid technique to reduce the operative time. Herein we have described the surgical repair of a giant incisional hernia using intraperitoneal Gore ePTFE dual-mesh plus (Gore-Tex; W. L. Gore, Flagstaff, Ariz, USA) in a 55-year-old man status-post renal transplantation. Total necrosis of dis…
PLASMA PROTEIN LOSS DURING SURGERY: BENEFICIAL EFFECTS OF ALBUMIN SUBSTITUTION
2001
Plasma protein loss during abdominal surgery is a known phenomenon, but its possible pathophysiological relevance has remained unknown. The present study evaluates the effects of albumin substitution on systemic and local hemodynamics and cellular interactions in the mesenteric microcirculation. Rats underwent median laparotomy and exteriorization of an ileal loop for intravital microscopy of the mesenteric microcirculation. Plasma protein concentrations, systemic and local hemodynamics were recorded during the follow up period, with or without albumin substitution. Depending on the time course of plasma protein loss in control experiments, 80% of the calculated protein loss was infused dur…
Permanent stenting in “unextractable” common bile duct stones in high risk patients. A prospective randomized study comparing two different stents
2007
BACKGROUND: Endoscopic sphincterotomy (ES) and stone extraction is the treatment of choice for bile duct stones. Therefore, if ES and conventional stone extraction fail, further treatment is mandatory. Insertion of a biliary endoprosthesis is an effective option. MATERIALS AND METHODS: We treated 30 high-risk patients (17 women and 13 men, mean age 82 years) affected by difficult common bile duct stones. The patients were randomly assigned preoperatively using closed envelopes (blind randomization) into two groups to receive insertion of polyethylene or hydrophilic hydromer-coated polyurethane stent, respectively. Follow-up was achieved by contacting referring physicians and patient's relat…
Damage to the vascular structures in inguinal hernia specimens.
2012
BACKGROUND: Few scientific reports to date describe the histological modification of structures outlining a hernia opening. This article is focused on the identification of the pathological changes in vascular structures in tissues excised from cadavers with inguinal hernia. A deeper comprehension of this topic could lead to essential improvements in the detection of hernia genesis. MATERIALS AND METHODS: Different kinds of hernia, including indirect, direct and mixed, were identified in 30 autopsied subjects. Tissue samples were resected for histological study from abdominal wall structures close to the hernia opening. Histological examination focused on the detection of structural changes…
Nerve degeneration in inguinal hernia specimens
2011
BACKGROUND: The histological study of the herniated inguinal area is rare in the literature. This report is focused on the detection of structural changes of the nerves within tissues bordering the inguinal hernia of cadavers. Their physiopathological consequences are hypothesized. MATERIALS AND METHODS: Primary inguinal hernia was diagnosed in 30 fresh cadavers. Tissue specimens from the inguinal region close to and around the hernia opening were excised for histological examination. A control of the data was achieved through tissue samples excised from equivalent sites of the inguinal region in 15 cadavers without hernia. RESULTS: The detected nerves in the inguinal area demonstrated path…
Surgical treatment of pancreatic cancer
1984
From 1964 to 1982, there were 782 patients treated for carcinoma of the pancreas. In 174 patients pancreaticoduodenal resection was possible (22%). Until 1977 we performed Whipple procedures, while from 1978 to 1982 total pancreatectomy was preferred. Comparing the results of both methods, we did not find any advantages of total pancreatectomy. Operative mortality did not decrease, survival time did not extend, and the higher resection rates (up to 26%) for more advanced tumor stages were accompanied by greater morbidity. With respect to the patients with inoperable cancer of the pancreas, we found over the last 5 years that the rate of those not undergoing surgery has climbed from 8% to 25…
