Surgical treatment of liver metastases from pancreatic cancer

HPB, Issue 2 2006
Hidehisa Yamada PhD
Abstract Pancreatic cancer is a disease with a poor prognosis. Most patients are diagnosed at an advanced and unresectable stage. Even if the primary cancer is radically removed, postoperative recurrence frequently occurs. Generally, metastatic liver tumors from pancreatic cancer are not indicated for surgical treatment. Here we evaluate the results of performing hepatectomy for liver metastases of pancreatic cancer. In our institute, six patients with liver metastases from pancreatic cancer were treated by partial hepatectomy. Overall 1-, 3- and 5-year survival rates of six patients after hepatectomy were 66.7%, 33.3% and 16.7%, respectively, and one patient was alive for 65.4 months. Performing a hepatectomy for liver metastases of pancreatic cancer, when combined with a pancreas resection, was recently considered to be a safe operation, and one that might offer prolonged survival for highly selected patients with curative resection of liver metastases. In the future, it will be necessary to develop new multi-modality therapies to improve the prognosis of pancreatic cancer. [source]

Management and prevention of postoperative Crohn's disease

INFLAMMATORY BOWEL DISEASES, Issue 10 2009
Miguel Regueiro MD
Abstract Postoperative Crohn's disease (CD) recurrence is a common occurrence after intestinal resection. Currently, the optimal management of patients who have undergone surgical resection is unknown and treatment remains subjective. Clinicians in conjunction with patients must balance the risks of recurrence against the potential risks associated with treatment. For those at very low risk of recurrence, no therapy may be needed; however, for patients at moderate risk immunomodulators should be considered. For those at highest risk of recurrence, biologic therapy, specifically antitumor necrosis factor agents, have emerged as appropriate treatment. Any postoperative management strategy should include a colonoscopy 6,12 months after surgery to identify recurrence. This review discusses current evidence for various pharmacologic approaches in the prevention of postoperative recurrence and provides guidance for clarifying patient risk.

Postoperative therapy for Crohn's disease

INFLAMMATORY BOWEL DISEASES, Issue 3 2009
Eric Blum MD
Abstract Prevention of the postoperative recurrence of Crohn's disease (CD) remains a challenging clinical problem. The majority of patients with CD will need surgery for treatment of the disease, most of these patients will develop recurrent symptoms within 5 years postoperatively, and many patients will need reoperation within 10 years. In patients with an ileocolic anastomosis, endoscopic recurrence precedes clinical recurrence and the severity of endoscopic recurrence correlates with the risk of clinical recurrence. Despite multiple studies, the best postoperative prophylactic therapy remains uncertain. Numerous randomized controlled trials of 5-aminosalicylates have shown only modest effect. Antibiotics, including metronidazole and ornidazole, decrease short-term, but not long-term endoscopic recurrence and are limited by side effects. Immunomodulators have yet to be extensively evaluated, although limited data suggest possible efficacy in preventing postoperative recurrence, particularly in high-risk patients. This review will evaluate the current state of the art therapy for postoperative prophylaxis in CD, with an emphasis on critical analysis of the available randomized controlled trials.

Could immunosuppressive drugs reduce recurrence rate after second resection for crohn disease?

INFLAMMATORY BOWEL DISEASES, Issue 5 2004
Arnaud Alves MD
Abstract Background: The aim of this study was to assess the possible benefit of postoperative immunosuppressive drugs administration (ie, azathioprine, 6-mercaptopurine, or methotrexate) on long-term surgical recurrence rate after second anastomotic ileocolonic resection. Methods: From 1984 to 2000, 26 patients with CD underwent second resection for ileocolonic anastomotic recurrence. There were 14 women and 12 men (mean age ± SD: 34 ± 9 years). Two groups of patients were compared according to the postoperative treatment: immunosuppressive (IS) drugs group was composed of 14 patients, and control group was composed of 12 patients receiving either salicylates (n = 5) or no treatment (n = 7). Results: Clinical recurrence rate at 3 years was significantly lower in the IS group than in the control group (3/12, 25% vs 6/10, 60%; P < 0.05). Although not significant, after a mean follow-up of 80 ± 46 months (extr. 17,178 months) after the second resection, clinical recurrence rate at follow-up was also lower in IS group (6/14, 43%) than in control group (9/12, 75%). The mean delay of recurrence was similar in both groups (27 ± 13 months vs 28 ± 21; NS). A third intestinal resection was performed less frequently in the IS group than in control group (2/14, 17% vs 7/12, 58%; P < 0.02). Conclusions: In patients treated with IS drugs, the rate of postoperative recurrence after second ileocolonic CD resection is lower than in untreated patients. Our results suggest that IS drugs should be evaluated prospectively for prevention of second postoperative CD recurrence. [source]


Virtual colonoscopy compared with conventional colonoscopy for stricturing postoperative recurrence in Crohn's disease

INFLAMMATORY BOWEL DISEASES, Issue 6 2003
Dr. Livia Biancone
Abstract Background The place of virtual colonoscopy (VC) in patients with Crohn's disease (CD) requiring endoscopic follow-up after surgery is unknown. The authors compared findings from VC versus conventional colonoscopy (CC) for assessing the postoperative recurrence of CD. Methods Sixteen patients with ileocolonic anastomosis for CD were prospectively enrolled from January 2001 to January 2002. Recurrence was assessed by CC according to Rutgeerts et al. VC was performed with a computed tomography scanner, with images examined by three radiologists who were unaware of the endoscopic findings. Results CC showed perianastomotic recurrence in 15 of 16 patients. Perianastomotic narrowing or stenosis was detected by VC in 11 of these 15 patients. There were 11 true positive, 1 true negative, 0 false-positive, and 4 false-negative findings (73% sensitivity, 100% specificity, 100% positive predictive value, 20% negative predictive value, 75% accuracy). Among the eight patients showing a rigid stenosis of the anastomosis not allowing passage of the colonoscope, VC detected narrowing or stenosis in seven patients. Conclusions The current findings suggest that although the widespread use of VC in CD is currently not indicated because of possible false-negative findings, this technique may represent an alternative to CC in noncompliant postsurgical patients with a rigid stenosis not allowing passage of the endoscope.

Prevention of relapse of Crohn's disease

INFLAMMATORY BOWEL DISEASES, Issue 4 2000
Dr. Lloyd R. Sutherland
Abstract Until a cure for Crohn's disease(s) is found, strategies that prolong the time spent in remission offer the greatest hope for reducing the morbidity and significant social costs associated with the disease. Medical therapy to date has been disappointing, and the search for a safe, effective therapy that could be offered at low cost continues. The aminosalicylates, so effective in ulcerative colitis, have shown, at best, minimal efficacy in maintaining remission in Crohn's disease. Conventional corticosteroids are not effective, and any reduction in time to relapse for budesonide-treated patients is measured in weeks not months. Azathioprine, 6-mercaptopurine, and methotrexate are effective in maintaining remission, but all three have significant side effects. Antibiotics may have a role to play. Biological therapy may be considered, but the issues of cost and long-term safety require evaluation. Future studies should segregate patients into two groups, those with a medically induced remission and patients whose concern is the prevention of postoperative recurrence. [source]


Surgical Ablation of Permanent Atrial Fibrillation by Means of Maze Radiofrequency:

JOURNAL OF CARDIAC SURGERY, Issue 5 2004
Mid-Term Results
We report our experience with a biatrial pattern of lesions based on the use of epicardial and endocardial radiofrequency ablation in an effort to minimize maze procedure. Method: In 85 patients undergoing cardiac surgery for established permanent atrial fibrillation (>3 months), a biauricular pattern of epicardic,endocardic maze lesions was performed. The main surgical procedures were diverse: 42 mitral valve surgeries, 7 mitrotricuspid valves, 18 mitroaortics, 4 mitroaortic and tricuspids, 2 aortic valves, 3 CABGs, 5 CABG and valve procedures, and 4 atrial septal defects. The mean age of the patients was 61 ± 12 (range 39,78). The mean duration of atrial fibrillation was 5.8 years (range 0.3 to 24). Results: Sixty-two (72.9%) patients presented postoperative supraventricular arrhythmia. Hospital mortality was seen in five patients (5.8%). Two patients died after a 12-month mean follow-up (range 2 to 32). A total of 14.1% of patients remained with their previous atrial fibrillation and 85.9% recovered and maintained sinus rhythm, with two patients having a permanent pacemaker. A total of 56% patients have been followed-up for a period of more than 6 months, and among them prevalence of sinus rhythm is 87.5%. Echocardiography detected biauricular contraction in 65% of them. After analyzing the data, factors involved in postoperative recurrence of atrial fibrillation after radiofrequency surgery were oldness of the atrial fibrillation (p < 0.01) and pre and postoperative left auricle volume (p < 0.04). Conclusion: Intraoperative radiofrequency has permitted us to perform the maze procedure in a simple way, with a low surgical morbid-mortality. We have obtained an 85.9% electrographic effectiveness and a 65% recovery of atrial contraction. Postoperative incidence of arrhythmia is the main postoperative problem. [source]

JOURNAL OF CLINICAL ULTRASOUND, Issue 7 2002
Verna Vanderpuye MBCHB
Abstract Purpose The aim of this prospective study was to evaluate the role of renal sonography and its use as an alternative to intravenous urography in detecting ureteral obstruction or hydronephrosis in patients with cervical cancer. Materials and Methods Patients with biopsy-confirmed carcinoma of the cervix who were referred to the radiotherapy center from February 6, 2001, through July 20, 2001, were enrolled in this trial. All patients had previously undergone clinical staging by physical examination and either intravenous urography or CT scanning as the standard tests for diagnosing ureteral obstruction or hydronephrosis. All patients underwent renal sonography as an alternative diagnostic tool for diagnosing ureteral obstruction or hydronephrosis. Results Forty patients were enrolled. Their mean age was 46 years (range, 26,65 years). According to the FIGO staging system, 12% of the patients had clinical stages 1B2 and 2A disease, 20% had stage 2B, 8% had stage 3A, 50% had stage 3B, and 10% had a postoperative recurrence of cervical cancer. Thirty-four patients had had intravenous urography and 6 had had CT scans of the abdomen and pelvis. Sensitivity, specificity, positive and negative predictive values and overall accuracy rates for renal sonography were 76.5% (13/17), 100% (23/23), 100% (13/13), 85% (23/27), and 90% (36/40), respectively. Seventy-five percent (3/4) of the false-negative results occurred in patients with pelvic sidewall thickening on physical examination. Conclusions Renal sonography may be used as an effective and relatively low-cost means of diagnosing ureteral obstruction in patients with cervical cancer without clinically evident pelvic sidewall thickening. © 2002 Wiley Periodicals, Inc.

Eversion Thrombectomy for Portal Vein Thrombosis During Liver Transplantation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 10 2002
Jérôme Dumortier
Portal vein thrombosis (PVT) has been seen as an obstacle to orthotopic liver transplantation (OLT), but recent data suggest that favorable results may be achieved in this group of patients. The aim of this study was to analyze the incidence, management, and survival of patients with PVT undergoing primary OLT with thrombectomy. Between October 1990 and August 2000, 468 liver transplantations were performed in our center and portal vein thrombosis was present in 38 patients (8.1%). Preoperative diagnosis, extension, intraoperative management, postoperative recurrence of portal vein thrombosis, and 1-year actuarial survival rates were retrospectively studied. Preoperative diagnosis was made in 17 cases (44.7%). In all patients, portal flow was restored after portal vein thrombectomy, followed by usual end-to-end portal anastomosis. All patients received preventive low-weight heparin from day 2 to hospital discharge, and then aspirin. Rethrombosis was observed in one patient with extended splanchnic thrombus. The 1-year actuarial patient survival rate was 83.7%, and did not significantly differ from the patients without portal vein thrombosis (86.7%). Our results suggest that portal vein thrombosis is often partial and thus difficult to diagnose preoperatively; it can be managed successfully during surgery by thrombectomy, except when there is complete splanchnic veins thrombosis; and it did not affect 1-year survival.

Melanoma antigen-1 mRNA combined with ,-fetoprotein mRNA levels in peripheral blood of patients with hepatocellular carcinoma: a predictor of postoperative recurrence or metastasis?

ANZ JOURNAL OF SURGERY, Issue 1-2 2009
Yuqing Zhang
Abstract Background:, The aim of the study was to identify whether melanoma antigen (MAGE)-1 mRNA and ,-fetoprotein (AFP) mRNA expressed in peripheral blood could be used to predict the recurrence and metastasis of hepatocellular carcinoma (HCC) after hepatectomy. Methods:, One hundred and forty-two HCC patients underwent hepatectomy. The control group includes 27 patients with chronic virus hepatitis and cirrhosis and 10 healthy volunteers. Peripheral blood samples were collected on the seventh day before operation, seventh day after operation and 30th day after operation. MAGE-1 mRNA and AFP mRNA were tested by nested reverse transcription polymerase chain reaction. Median follow up was 25.5 months (range 4,40 months). Patient survival, disease-free survival and clinicopathological features were compared between patients with positive and negative MAGE-1 mRNA and/or AFP mRNA. Results:, The expression of MAGE-1 mRNA and/or AFP mRNA in peripheral blood was closely correlated to the pathological stage and the positive ratio of tumour cells in the peripheral blood (P < 0.01). There was recurrence and/or metastasis after operation in 55 of 142 HCC patients. Among the 55 patients who had recurrence or metastasis, MAGE-1 mRNA and/or AFP mRNA in peripheral blood were persistently detected after operation in 38 patients and MAGE-1 mRNA and AFP mRNA turned to positive after operation in 14 patients. In contrast, no recurrence was found in 62 patients whose MAGE-1 mRNA and/or AFP mRNA turned to negative after operation. 88.1% (52 of 59) of patients with MAGE-1 mRNA and/or AFP mRNA persistently positive after operation showed recurrence or metastasis, whereas only 3.6% patients (3 of 83) with the negative of MAGE-1 mRNA and/or AFP mRNA after operation showed recurrence or metastasis (P < 0.001). Conclusion:, Melanoma antigen-1 mRNA combined with AFP mRNA in peripheral blood after hepatectomy is more sensitive and specific than AFP mRNA singly for predicting the recurrence and metastasis of the HCC patients, whereas preoperative transient detection is not.

Multiple hereditary glomangiomas: Successful treatment with sclerotherapy

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 1 2002
Kurosh Parsi
SUMMARY Glomangiomas are characterized by cavernous vascular channels surrounded by glomus cells. Multiple glomangiomas, although usually painless, can be a few centimetres in size and appear as blue phlebectatic lesions. Surgical excision of multiple glomangiomas can lead to scarring and recurrences. Laser treatment using vascular lasers and CO2 lasers has been useful in small, superficial lesions. We present the successful sclerotherapy treatment of multiple glomangiomas using sodium tetradecyl sulphate in a 59-year-old man who presented with postoperative recurrence of multiple lesions.

Influence of laparoscopy on postoperative recurrence and survival in patients with ruptured hepatocellular carcinoma undergoing hepatic resection

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2004
B. H. H. Lang
Background: Use of laparoscopy in patients with gastrointestinal cancer has been associated with port-site and peritoneal tumour metastases. The effect of laparoscopy on tumour recurrence and long-term survival in patients undergoing resection of ruptured hepatocellular carcinoma (HCC) remains unknown. Methods: Between June 1994 and December 2001, 59 patients with ruptured HCC underwent surgical exploration with a view to hepatic resection. Laparoscopy with laparoscopic ultrasonography was performed in 33 patients; the other 26 patients underwent exploratory laparotomy without laparoscopy. Perioperative and long-term outcomes were compared between the two groups. Results: Exploratory laparotomy was avoided in 12 of 13 patients with irresectable HCC who had a laparoscopy. The hospital stay of these 12 patients was significantly shorter than that of eight patients found to have irresectable HCC at exploratory laparotomy (median 11 versus 15 days; P = 0·043). Twenty patients had a laparoscopy followed by open resection of HCC, whereas 18 patients underwent laparotomy and resection without laparoscopy. There were no significant differences in disease-free (16 versus 19 per cent; P = 0·525) and overall (32 versus 48 per cent; P = 0·176) survival at 3 years between the two groups. The tumour recurrence pattern was similar between the two groups, and there were no port-site or wound metastases. Conclusion: Use of diagnostic laparoscopy in patients with ruptured HCC helps avoid unnecessary exploratory laparotomy. The present data suggest that laparoscopy does not have an adverse effect on tumour recurrence or survival in patients who undergo resection. Copyright © 2004 British Journal of Surgery Society Ltd.

Eliminating the Limitations of Manual Crimping in Stapes Surgery?

THE LARYNGOSCOPE, Issue 2 2005
A Preliminary Trial with the Shape Memory Nitinol Stapes Piston
Abstract Objective: Manual piston malcrimping in stapedotomy may be the major cause of the occurrence of the significant, interindividual variations of postoperative air-bone gap (ABG), air-bone gap closures (ABGC), and postoperative recurrences of conductive hearing loss. To eliminate the effects of manual crimping on stapedotomy outcomes, the self-crimping, shape memory alloy Nitinol stapes piston was investigated and hearing evaluated. Study design: Prospective, preliminary case-control study in a tertiary care referral center. Methods: Sixteen patients with otosclerosis undergoing reversed stapedotomy using the Nitinol stapes piston were matched to reference patients out of our conventional titanium piston database. The effects of the self-crimping Nitinol piston on the postoperative ABGC, the postoperative air-bone gap (ABG) variations, and the postoperative short-term hearing results were investigated 3, 6 and 9 months postoperatively. These data were statistically compared with the results of the control patients in our titanium stapes piston database. Results: The mean postoperative ABG and the interindividual variations of the postoperative ABG were significantly smaller in the Nitinol group, the extent of ABGC greater in the Nitinol piston group, but not significant. The postoperative short-term stability of ABGC was similar in both groups. No infections or adverse reactions occurred during follow-up. Conclusion: Our preliminary results suggest that the self-crimping shape memory alloy Nitinol stapes piston eliminates the limitations of manual malcrimping in stapedotomy, thus optimising the surgical procedure. This allows reliable, safe, and consistent air-bone-gap closure in patients with otosclerosis up to 1 year after surgery. [source]
