Liver transplantation for hepatocellular carcinoma--is there a risk of recurrence caused by intraoperative blood salvage autotransfusion?

2011

<i>Background/Aims:</i> The use of intraoperative blood salvage autotransfusion (IBSA) during surgical approaches may contribute to tumour cell dissemination. Therefore, IBSA should be avoided in cases of malignancy. However, the risks of IBSA might be acceptable in liver transplantation (LT) for selected small hepatocellular carcinoma (HCC). <i>Methods:</i> In total, 136 recipients of LT with histologically proven HCC in the explanted liver were included in this analysis. With regard to tumour recurrence, 40 patients receiving IBSA despite HCC (IBSA group) were compared to 96 patients without IBSA (non-IBSA group). <i>Results:</i> Milan criteria as asses…

Survival and recurrence after liver transplantation versus liver resection for hepatocellular carcinoma: a retrospective analysis.

1998

Objective This study compares the results of liver transplantation (LTx) and liver resection (LR) for hepatocellular carcinoma (HCC) to test the widespread hypothesis that LTx is the preferable approach for small HCCs. Summary Background Data With respect to scarcity of donor organs and poor results, LTxs for large HCCs are obsolete. Small HCC transplantations have been reported to result in an excellent survival rate. However, the data of comparative studies are controversial. Methods Patients who were treated curatively by LTx (n = 50) or LR (n = 52) for HCC were included in this retrospective study. Survival and freedom from recurrence were analyzed. Patients were stratified according to…

Permanent Stoma After Low Anterior Resection for Rectal Cancer

2010

BACKGROUND AND OBJECTIVES: A low anterior resection procedure for removing a rectal tumor aims to preserve the sphincter and avoid a permanent stoma. Permanent stomas are primarily necessary in cases of poor anorectal function and local recurrence. The aim of this study was to clarify whether anastomosis-related complications and local recurrence influenced the rate of permanent stomas in a long-term follow-up. METHODS: Of 1032 consecutive patients with rectal cancer, 397 were treated by low anterior resection (R0 and R1 resections) between 1985 and 2007 at the Department of General and Abdominal Surgery of the University Hospital, Mainz (Germany). All patient data were collected prospectiv…

Radiofrequency ablation as first-line treatment in patients with early colorectal liver metastases amenable to surgery.

2010

Aiming at avoidance of futile surgery, we have tested whether radiofrequency ablation (RFA) may be used as first-line treatment in patients with colorectal metastases (CRLM) occurring within the first year after colorectal surgery.Surgical resection is the standard treatment in patients with CRLM. Major retrospective analyses have identified the interval between colorectal surgery and the occurrence of CRLM to be of prognostic importance. So far, it is unknown whether survival of the respective patients is hampered if RFA is used as first-line treatment.According to a clinical pathway, we have treated patients with CRLM detected within the first year after colorectal surgery preferentially …

Cryotherapy for liver metastases

2000

Cryotherapy is undergoing a renaissance in the treatment of nonresectable liver tumors. In a prospective case control study we assessed the morbidity, mortality, and efficacy of hepatic cryotherapy for liver metastases. Between January 1996 and September 1999 a total of 54 cryosurgical procedures were performed on 49 patients (median age 66 years, 21 women) with liver metastases. Patient, tumor, and operative details were recorded prospectively. Liver metastases originated from colorectal cancer (n=37), gastric cancer (n=3), renal cell carcinoma (n=2), and other primaries (n=7). Median follow-up was 13 months (1-32). The median number of liver metastases was 3 (range 1-10) with a median dia…

Avoidance of Overtreatment of Rectal Cancer by Selective Chemoradiotherapy: Results of the Optimized Surgery and MRI-Based Multimodal Therapy Trial.

2020

Background Neoadjuvant chemoradiotherapy (nCRT) in patients with rectal cancer carries a high risk of adverse effects. The aim of this study was to examine the selective application of nCRT based on patient risk profile, as determined by MRI, to find the optimal range between undertreatment and overtreatment. Study Design In this prospective multicenter observational study, nCRT before total mesorectal excision (TME) was indicated in high-risk patients with involved or threatened mesorectal fascia (≤1 mm), or cT4 or cT3 carcinomas of the lower rectal third. All other patients received primary surgery. Results Of the 1,093 patients, 878 (80.3%) were treated according to the protocol, 526 pat…

Integrating Downstaging in the Risk Assessment of Patients With Locally Advanced Rectal Cancer Treated With Neoadjuvant Chemoradiotherapy: Validation…

2017

Abstract Background Adjuvant chemotherapy is controversial in patients with locally advanced rectal cancer after preoperative chemoradiation. Valentini et al developed 3 nomograms (VN) to predict outcomes in these patients. The neoadjuvant rectal score (NAR) was developed after VN to predict survival. We aimed to validate these tools in a retrospective cohort at an academic institution. Patients and Methods VN and the NAR were applied to 158 consecutive patients with locally advanced rectal cancer treated with chemoradiation followed by surgery. According to the score, they were divided into low, intermediate, or high risk of relapse or death. For statistical analysis, we performed Kaplan-M…

Subfascial Endoscopic Perforator Surgery With Tumescent Local Anesthesia

2002

background. Subfascial endoscopic perforator surgery (SEPS) has become an established procedure. objective. To evaluate SEPS with tumescent local anesthesia (TLA) using an single-port device originally designed for that purpose. methods. Patients selected for SEPS received subcutaneous infiltration of TLA into the medial aspect of the calf 20 minutes before surgery. Bipolar coagulation and dissection were used to treat incompetent perforators. results. Fifty-one patients with 67 legs of CEAP stages C3–C6 underwent SEPS with TLA. In 40 patients or 53 legs (79.1%) TLA alone allowed successful completion of the SEPS procedure. Five patients with 7 legs (10.4%) required additional intravenous a…

Correction of Constricted Ear

1995

We present a case of moderate constricted ear corrected using a modified Tanzer's technique for the helical deformity and lengthening the lower third of the pinna with a cutaneous transposition flap from the retroauricular area. The operation begins with a rapid intraoperative expansion of the retroauricular skin. Then an incision is made on the posteromedial ear aspect and the ear is degloved using a subperichondral plane. The upper pole of the cartilage is expanded and rearranged by an anteriorly pedicled helical flap and a cartilaginous graft is taken from the constricted part of the concha. The lower third of the pinna is lengthened by a cutaneous transposition flap from the retroauricu…

Reduced recanalization rates of the great saphenous vein after endovenous laser treatment with increased energy dosing: Definition of a threshold for…

2006

Background Recent reports indicated a correlation between the amount of energy released during endovenous laser treatment (ELT) of the great saphenous vein (GSV) and the success and durability of the procedure. Our objective was to analyze the influence of increased energy dosing on immediate occlusion and recanalization rates after ELT of the GSV. Methods GSVs were treated with either 15 or 30 W of laser power by using a 940-nm diode laser with continuous fiber pullback and tumescent local anesthesia. Patients were followed up prospectively with duplex ultrasonography at day 1 and at 1, 3, 6, and 12 months. Results A total of 114 GSVs were treated with 15 W, and 149 GSVs were treated with …
