Incisional hernia recurrence following "vest-over-pants" or vertical Mayo repair of primary hernias of the midline.

A series of 68 primary midline incisional hernias with a vertical Mayo repair was evaluated retrospectively. Patients without documented hernia recurrence following this repair were invited for physical examination. Life-table methods were used for statistical analysis. The 1-, 3-, 5-, and 10-year cumulative recurrence rates were 35%, 46%, 48%, and 54%, respectively. Also, generally accepted risk factors were studied. Multivariate analysis identified the size of the hernia (p = 0.02) and the use of steroids (p = 0.04) as the most important independent risk factors of first time recurrent incisional hernia. Considering the high recurrence rates found, the results of this study strongly suggest that the vest-over-pants repair should no longer be used for closure of midline incisional hernias.

[Linear-accelerator-based stereotactic irradiation for metastatic brain tumors].

To assess the safety and availability of stereotactic radiotherapy (SRT) for metastatic brain tumors, we reviewed 54 consecutive cases with a total of 118 brain metastases treated with linear-accelerator-based stereotactic irradiation (STI). Nineteen patients with a total of 27 brain tumors that were larger than 3 cm or close to critical normal tissues were treated with SRT. The marginal dose of SRT was 15-21 Gy (median 21 Gy) in 3 fractions for 3 days. The median marginal dose of stereotactic radiosurgery (SRS) was 20 Gy. Effective rates of imaging studies were 72.7% and 94.4%, and those of clinical symptoms were 46.7% and 55.6% for SRT and SRS, respectively. One-year and two-year survival rates of SRT were 40.9% and 17.6%, respectively, and the median follow-up period was 6.4 months. The one-year survival rate of SRS was 32.7%, with a median follow-up of 4.6 months. Fourteen cases (7 cases each) had recurrent tumors at STI sites. Early complications were observed in one case of SRT and 8 cases of SRS, and late complications occurred in 3 cases of SRS. There were no significant differences among effective rates, survival rates, median follow-up times, recurrence rates, and complications between SRT and SRS. We concluded that SRT is a safe, effective therapy for large or eloquent area metastases.

Botulinum toxin injection as a diagnostic tool for verification of sphincter of Oddi dysfunction causing recurrent pancreatitis.

Sphincter of Oddi dyskinesia (SOD) is among the less frequent causes of acute recurrent pancreatitis. We report on a patient with frequent pain attacks accompanied by pancreatic enzyme elevation, in whom a transitory decrease of the SO pressure following endoscopic botulinus toxin injection was a diagnostic clue for SOD. The patient's symptoms resolved for 4 months, after which time recurrent symptoms paralleled the reoccurrence of the elevated SO pressure. Endoscopic sphincterotomy of the biliary sphincter relieved her symptoms for the subsequent follow-up period which is now 10 months.

Recurrent hepatitis B, hepatitis C, and combined hepatitis B and C in liver allografts: a comparative pathological study.

Although recurrence of viral hepatitis in liver transplants is common, data comparing recurrent hepatitis B (HB), hepatitis C (HC), and co-existing dual hepatitis B and C (HB&C) are sparse. Posttransplantation liver biopsies, along with molecular, serological, immunohistochemical, and clinical data from 27 patients with pretransplantation diagnosis of chronic viral hepatitis, were reviewed. The patients were placed into 4 groups: Group I, with pretransplantation HB (n = 8); group II, with pretransplantation HC (n = 10); group III with pretransplantation HC and anti-HB surface or core antibody (n = 4); and group IV, with pretransplantation HB&C (n = 5). The histopathologic findings and patient outcome were compared in the 4 groups. A high rate of recurrence of viral hepatitis was seen for all 4 groups: Group I = 100%, group II = 90%, Group III = 100%, and group IV = 80%, with the mean (median) recurrence time of 308 (224), 82 (52), 61 (64), and 125 (70) days, respectively. The number of deaths (their median survival times) were: group I = 4 (374 days), group II = 4 (794 days), group III = 1 (1,143 days), and group IV = 5 (448 days). The earliest histological findings of lobular injury was the presence of acidophil bodies and Kupffer cell hyperplasia, the latter being more prominent in recurrent HC cases. Recurrent HB presented in 2 forms: early (before 150 days) with poor survival and with either severe necroinflammatory histology or with features of fibrosing cholestatic hepatitis, and delayed (after 150 days), with mild necro-inflammatory activity and prolonged survival. HC with or without anti-HB antibodies had early recurrence, but the course was slowly progressive. Patients with HB&C had recurrence of both viruses; however, the course was dictated by HB virus.

Acute drug testing with nitrates: angina relief during treadmill exercise.

To evaluate the effect of sublingual nitroglycerin (N) and chewable isosorbide dinitrate (I) in patients with angina pectoris, 12 subjects underwent treadmill exercise to the point of onset of angina. At that juncture, N or I or placebo (P) was administered and walking was continued until moderately severe angina recurred. For those patients who completed the initial 10-minute exercise period, testing was repeated until moderately severe angina recurred or until a total test time of three hours elapsed. Retesting ensured that each patient was tested separately with N, I and P within a two-week period. Within the I group, four patients experienced the onset of angina relief (AR) at 10 minutes (') 6 seconds (*) +/- 3' 4" with a mean recurrence time (RT) of 154' 3" +/- 4' 27" (P less than or equal to 0.05), for a significant difference. Within the N group, six patients had AR of 8' 3" +/- 1' 1" with an RT of 49' 39" +/- 1' 15" (P less than or equal to 0.01), for a significant effect. Within the P group, only one patient experienced AR. For all other patients in each group, testing was terminated because of moderately severe angina in the 5-8' period of the first test. In comparing subgroups for RT during I therapy (4 patients) versus N therapy (6 patients), a significant difference was noted (154' 3" +/- 27" versus 49' 39" +/- 1' 15") (P less than 0.05). The data suggest a possible benefit of I in selected patients. The effect may last as long as three to four hours. There is also an enhanced benefit of N with the patient in the upright position. This effect may last as long as 40-50'. Treadmill testing is recommended with nitrate administration to determine which drug (I or N) is the more suitable for the specific patient.

A long-term follow-up and management study of hepatocellular carcinoma patients surviving for 10 years or longer after curative hepatectomy.

BACKGROUND: The aims of the current study were to elucidate the clinicopathologic characteristics and disease recurrence patterns of patients with hepatocellular carcinoma (HCC) who survived for 10 years or longer after undergoing an initial hepatectomy. METHODS: Between January 1987 and December 1993, 578 patients underwent potentially curative hepatectomy at the study institution. Disease recurrence and follow-up data were available for 481 of these patients, who then were followed for more than 10 years after the initial hepatectomy. Fourteen clinicopathologic features were compared between the 10-year survivors and those patients who died within 10 years after the surgery. The risk factors for disease recurrence, the recurrence status, time to recurrence, and treatment modalities for recurrence were examined among the 10-year survivors. RESULTS: There were 105 10-year survivors (21.8%), including 42 disease-free survivors (8.7%). Favorable independent factors found to be correlated with 10-year survival were age < 55 years, a plasma retention rate of indocyanine green at 15 minutes of < 15%, the presence of a solitary tumor, the absence of intrahepatic metastases, the absence of portal vein invasion, and the absence of underlying cirrhosis. A negative test for the the hepatitis C antibody and the absence of intrahepatic metastases were found to be independent predictive factors for 10-year disease-free survival among the 10-year survivors. CONCLUSIONS: The results suggest that younger patients without underlying cirrhosis who have a solitary HCC that does not demonstrate vascular invasion might survive for longer than 10 years after the initial hepatectomy. In addition to close surveillance in such patients after hepatectomy, repeat hepatectomy, local ablation therapy, and transhepatic arterial chemoembolization may contribute to long-term survival, even if disease recurrence occurs.

Recurrence-free survival time for surgically treated soft tissue sarcoma patients. Multivariate analysis of five prognostic factors.

A staging system, based upon the experience of 1215 patients, was published by the American Joint Committee Task Force on Soft Tissue Sarcoma in 1977. A subset of these patients, 594, was selected to study recurrence-free survival time. The authors found 331 patients with a recurrence within 5 years (100 local only, 123 metastatic only, and 108 local + metastatic); median months to recurrence was 9.7. Within 5 years, recurrence was clearly associated with mortality: among the 331 patients who experienced a recurrence, 245 died, whereas only 31 died among the 263 who had no recurrence. To further evaluate the utility of the published staging system, a multivariate analysis of five factors was carried out for 297 of the 594 patients (patients with unknown information for any one of these factors were excluded). Factors in addition to grade that exerted a significant influence on recurrence were: direct extension, symptoms, and location of tumor when survival was measured to the first of any recurrence, and tumor size, measuring survival to the first metastatic recurrence. It is therefore recommended that these factors be taken into account in staging this disease. Estimates of probable recurrence-free survival time based upon the multivariate model (Weibull) are also presented.

[Effects of chemotherapy in recurrent endometrial carcinoma].

OBJECTIVE: To explore the effects of chemotherapy in recurrent endometrial carcinoma. METHODS: A retrospective study was carried out on the clinical data of 20 cases of recurrent endometrial carcinoma hospitalized from May. 1992 to Jun. 2002. RESULTS: The recurrence rate of these 20 cases was 11.0%. The recurrence occurred (17 +/- 10) months after the first therapy. Eleven of the 20 patients (55.0%) had accepted chemotherapy with (6 +/- 4) courses and were followed up for (17 +/- 16) months after the second therapy. Fifteen cases (75.0%) died of cancer, 4 cases survived with tumor, and only 1 case (5.0%) was tumor-free. Univariate model revealed that chemotherapy and number of chemotherapy course were related with the prognosis (P = 0.0146, P = 0.0353). Radiotherapy affected the prognosis too (P = 0.0414). But pathologic subtype, stage, tumor cell differentiation, age, recurrent time, surgery, chemotherapy scheme, drug infusion way , and endocrine therapy had no relation with the prognosis (P = 0.5517, 0.5763, 0.1879, 0.880, 0.453, 0.0672, 0.0795, 0.5956, and 0.2035). Multivariate model revealed that chemotherapy had influence on the prognosis (beta = -1.349, OR = 0.259, P = 0.026). CONCLUSION: Combined treatment raises the survival of the recurrent endometrial carcinoma patients, in which chemotherapy plays a leading role and influences the prognosis remarkably.

Primary lymphoma of the calcaneus with recurrence in the distal tibia: a case report.

Primary lymphoma of bone in general is a very rare condition which represents approximately 3% of all primary malignant bone tumors. Of these, less than 1% originate in the foot. The following case presentation demonstrates a patient who presented with primary lymphoma of the calcaneus, diagnosed by open bone biopsy and treated with radiation therapy. The patient remained disease free for almost 3 years, at which time recurrence to the contralateral distal tibia was diagnosed again through open biopsy.

[An analysis of pathologic features and prognostic factors of 10 cases with pseudomyxoma peritonei].

OBJECTIVE: To investigate the histogenesis and the pathological features of pseudomyxoma peritonei and to analysis its prognostic factors. METHODS: Ten cases with pseudomyxoma peritonei were clinicopathologically studies, with follown-up at least 24 monthes. All histopathological sections and clinical data were reviewed. RESULTS: Seven out of 10 patients had the ovarian mucinous tumors which were bilateral in 5 cases (71.4%). Histopathologically, 4 of 7 cases with ovarian tumor were characterized by the presence of the multifocal bleeding, fragmental necrosis, and occasionally, the striated border on the glandular lumens. The mucinous epithelial cells and mucin invased into the peritonei, destroyed normal structure, and formed the desmoplasia. Four patients died of pseudomyxoma peritonei, all with extensive lesions, invasions in the peritonei, and a short recurrent time (mean, 12.0 monthes) after presentation. CONCLUSIONS: The histogenesis of pseudomyxoma peritonei is heterogenous, the presence of possible metastases including from the appendix, the colon and other organs. The most important factors of the prognosis should include the extent of initial lesions, the presence of invasion in the peritonei and a rapid recurrence.

High preoperative serum carcinoembryonic antigen predicts metastatic recurrence in potentially curative colonic cancer: results of a five-year study.

INTRODUCTION: Serum carcinoembryonic antigen is used mainly for tumor follow-up to detect recurrence of colonic cancer. However, raised preoperative carcinoembryonic antigen levels may be helpful for the identification of understaged cases and of patients meriting more intensive preoperative and postoperative diagnostic workup. METHODS: From a prospectively collected database, the data on 261 patients who had curative colonic carcinoma with a minimal follow-up of five years and who had preoperative carcinoembryonic antigen levels assessed were retrieved and analyzed. Outcome parameters were local and/or distant recurrence and time to recurrence. These parameters were correlated with Dukes staging and preoperative carcinoembryonic antigen levels. RESULTS: The cumulative disease-free survival of patients with a preoperative carcinoembryonic antigen level within the normal range was significantly better than that of those whose carcinoembryonic antigen was 5 ng/ml or more (P = 0.001). No patient with carcinoembryonic antigen levels less than 1 ng/ml developed metastatic recurrence. Twenty-three percent of all patients with a raised carcinoembryonic antigen above 5 ng/ml compared with 2.1 percent of patients with carcinoembryonic antigen below 5 ng/ml developed a metastasis at two years. At five years, these figures were 37.2 percent and 7.5 percent, respectively. Dukes staging and carcinoembryonic antigen levels were found to be directly correlated (P < 0.001) when all patients were included. Carcinoembryonic antigen of more of 15 ng/ml was found to be a significant adverse prognostic indicator for disease-free survival irrespective of Dukes staging (P < 0.02). Raised carcinoembryonic antigen levels predicted distant metastatic recurrence (P < 0.001) but did not predict local recurrence (P = 0.72). CONCLUSIONS: High preoperative carcinoembryonic antigen levels above 15 ng/ml predicted an increased risk of metastatic recurrence in potentially curative colonic cancer and may indicate undetectable disseminated disease. Preoperative carcinoembryonic antigen levels predict understaging and the possibility of distant recurrence. Such patients may therefore be selected for adjuvant therapy where indicated. Therefore, carcinoembryonic antigen is complementary to conventional Dukes staging for the prediction of recurrence and survival.

[Pathological study on the metastatic routes of bile duct carcinoma].

Multiple staining was performed on resected tumors. Samples after curative surgery in 40 cases of bile duct carcinoma for observation of tumor blood vessel density (TVD), and perineural invasion index (PNI). Lymphatic invasion was found in 29 cases (72.5%), blood vessel invasion in 31 (77.5%), and PNI in 33 (82.5%). TVD and PNI were positively correlated with metastasis. Three years after operation, the recurrent rate was 100%, with an averaging recurrent time of 9.6 months in the metastatic group in contrast to 64.3% and 17.5 months in those without metastasis.

[Diagnosis and management of Crohn disease complicated with gastrointestinal fistulae].

OBJECTIVE: To investigate the diagnosis and treatment of patients with Crohn disease (CD) complicated with gastrointestinal fistulae. METHODS: Clinical data of sixty-two cases with CD complicated with gastrointestinal fistula e from 1978 to 2004 were analyzed. RESULTS: These were 68 external fistulae in 6 2 patients including recurrent fistulae in 6 cases, internal fistulae in 8 cases . Twenty- seven fistulae were located in the terminal ileum and 21 fistulae wer e located in ileocolic anastomosis site. The main surgery included 14 ileocecal resections with primary anastomosis and 26 resections of original ileocolic anastomosis with fistula and re-anastomosis. The incidence of recurrence was lower (15.4% ) in patients with postoperative medication including sulfasalazine and immunomodulator than that (34.8% ) in patients without postoperative immunomodulator,but the recurrence time was longer [(40+/- 17) months] in patients with postoperative medication than that [(8+/- 3)months] in the patients without postoperative specific medication. CONCLUSIONS: Most CD fistulae are external fistulae,most of the external fistulae are treated by resection of the fistula and anastomosis. Specific medication including sulfasalazine,mesalamine and immunomodulators should be used to prevent postoperative complications and CD recurrence.

Size and timing of local recurrence predicts metastasis in soft tissue sarcoma. Growth rate index retrospectively analyzed in 134 patients.

Our study combined size and timing of the first local recurrence to create a growth rate index (GRI-ratio of size (cm) to timing (mo)) which we analyzed for an association with metastasis. We analyzed 134 locally recurrent tumors from a series of 460 adult patients with soft tissue sarcoma of the extremities and trunk wall who were diagnosed and treated between 1964 and 1990, with a median follow-up of 10 (2-28) years for survivors. None of the patients had metastases at diagnosis. One half (74) of local recurrences were from inadequately treated primaries, one half (71) were associated with metastases, and two thirds (89) were seen in non-center-treated patients. There were equal numbers of patients with GRI < or = 0.4 (low) and > 0.4 (high). Patients with a low GRI had a better 2-year metastasis-free survival (80 percent) than those with a high GRI (30 percent). High GRIs were associated with large, high grade primary tumors and a short metastasis-free interval in comparison to low GRI tumors. Time to local recurrence strongly correlated with the time to metastasis (R2 0.85, p < 0.001). GRI was a good discriminator of metastasis in patients with tumors larger than 5 cm and of malignancy grade IV. Our study suggests that clinical characteristics (e.g., GRI) of local recurrence rather than presence, per se, are important in predicting tumor behavior.

Recurrence of idiopathic pulmonary hemosiderosis in a young adult patient after bilateral single-lung transplantation.

BACKGROUND: Idiopathic pulmonary hemosiderosis (IPH) is a rare disease of unknown etiology characterized by hemoptysis, diffuse pulmonary infiltration, and anemia. Diagnosis requires a detailed clinical history and transbronchial lung biopsy (TLB). METHODS AND RESULTS: A 19-year-old man developed progressive dyspnea, hemoptysis, and anemia. The chest x-rays showed bilateral opacities. IPH was diagnosed on the basis of clinical findings and TLB. The patient was treated with corticosteroidal therapy. His respiratory function worsened, and he underwent lung transplantation in 1997. The pathological examination on native lungs confirmed the previous histologic diagnosis. In 2000, the patient again developed hemoptysis, fever, and hypoxemia. A recurrence of the disease was established by TLB. CONCLUSIONS: This is the first report of recurring IPH. The possibility of recurrent IPH raises the question whether these patients should be disqualified from lung transplantation. This question is unanswerable because incidence of recurrence, time course, and impact on the graft function are presently unknown and unpredictable.

Case-control methods in the presence of multiple failure times and competing risks.

The link between cohort and incident case-control studies has been considered by many authors. In particular, under the Cox proportional hazards model, follow-up data (implicit or explicit) can be analyzed as a case-control study by randomly selecting controls from the risk sets of each incident case, thereby obviating the necessity of working with the entire cohort when interest is primarily on exposure effects. This paper extends this linkage to competing risks and to diseases with multiple incidence or recurrence times by matching to each event (case) a sample of controls from the appropriate risk set. Illustrations are given.

Long-term follow-up of a randomized controlled trial of suture versus mesh repair of incisional hernia.

OBJECTIVE: The objective of this study was to determine the best treatment of incisional hernia, taking into account recurrence, complications, discomfort, cosmetic result, and patient satisfaction. BACKGROUND: Long-term results of incisional hernia repair are lacking. Retrospective studies and the midterm results of this study indicate that mesh repair is superior to suture repair. However, many surgeons are still performing suture repair. METHODS: Between 1992 and 1998, a multicenter trial was performed, in which 181 eligible patients with a primary or first-time recurrent midline incisional hernia were randomly assigned to suture or mesh repair. In 2003, follow-up was updated. RESULTS: Median follow-up was 75 months for suture repair and 81 months for mesh repair patients. The 10-year cumulative rate of recurrence was 63% for suture repair and 32% for mesh repair (P < 0.001). Abdominal aneurysm (P = 0.01) and wound infection (P = 0.02) were identified as independent risk factors for recurrence. In patients with small incisional hernias, the recurrence rates were 67% after suture repair and 17% after mesh repair (P = 0.003). One hundred twenty-six patients completed long-term follow-up (median follow-up 98 months). In the mesh repair group, 17% suffered a complication, compared with 8% in the suture repair group (P = 0.17). Abdominal pain was more frequent in suture repair patients (P = 0.01), but there was no difference in scar pain, cosmetic result, and patient satisfaction. CONCLUSIONS: Mesh repair results in a lower recurrence rate and less abdominal pain and does not result in more complications than suture repair. Suture repair of incisional hernia should be abandoned.

Adverse effects of preoperative hepatic artery chemoembolization for resectable hepatocellular carcinoma: a retrospective comparison of 138 liver resections.

During the past 8 years we have treated 268 patients with primary hepatocellular carcinoma (HCC); total extirpation of the tumor was carried out in 138. Thirty-one of the patients with resectable HCCs had already been treated with transcatheter arterial embolization (TAE) of the liver before they were referred to us. The clinical values of preoperative TAE were retrospectively evaluated for those 31 patients and for the remaining 107 patients without TAE. There were no substantial differences between the two study groups in the clinical and histopathologic backgrounds. No differences were observed in the extent of liver resection, estimated blood loss during surgery, and operation time. During surgery, however, troublesome intra-abdominal complications relevant to TAE were encountered in 15 patients, and detection of tumors was impossible, even with intraoperative ultrasonography, in five patients in the group with TAE. Such findings were not present in any of the patients without TAE. Postoperative morbidity and mortality rates were similar in the two groups. There was no significant difference in the rate of recurrence of tumor in the liver, but the recurrence time was significantly shorter in the group with TAE. TAE did not improve the long-term survival rates in patients either with or without cirrhosis. Results of our study seem to indicate that preoperative TAE is meaningless in the treatment of resectable HCCs and therefore should be avoided, particularly in patients with advanced cirrhosis of the liver.
