Microcystic adenoma or serous cystadenoma is an uncommon tumor and accounts for 1-2% of the exocrine neoplasms of the pancreas. Usually unifocal, they present as single, large, well-demarcated multiloculated cystic tumors, ranging in size from 1 to 25 cm. Multifocal variants or diffuse serous cystadenomas are extremely rare. We present 2 cases of which 1 is a diffuse variant affecting the body, tail and part of the neck of the pancreas. In both the patients the tumors were detected incidentally. We highlight on the diffuse variant in view of its rarity and present a review of literature. In this case the entire body and tail of the pancreas was spongy replaced by multicystic lobules and hyalinized fibrocollagenous stroma. The cysts were lined by low cuboidal glycogen containing bland cells. Such a unique presentation wherein the entire body and tail of the pancreas is replaced with multiple cysts is a diffuse presentation of microcystic adenoma and a search through literature revealed only 7 such cases among the 15 cases with multifocal presentation reported. 相似文献

Background
Although the impact of Aboriginal status on HIV incidence, HIV disease progression, and access to treatment has been investigated previously, little is known about the relationship between Aboriginal ethnicity and outcomes associated with highly active antiretroviral therapy (HAART). We undertook the present analysis to determine if Aboriginal and non-Aboriginal persons respond differently to HAART by measuring HIV plasma viral load response, CD4 cell response and time to all-cause mortality. 相似文献3.

AIM: The present study evaluates the performance of the POSSUM, the American Society of Anesthetists (ASA), APACHE and Childs classification in predicting mortality and morbidity in hepatopancreaticobiliary (HPB) surgery. We describe especially the limitations and advantages of risk in stratifying the patients. METHODS: We investigated 177 randomly chosen patients undergoing elective complex HPB surgery in a single institution with a total of 71 pre-operative and intra-operative risk factors. Primary endpoint was in-hospital mortality and morbidity. Ordered logistic regression analysis was used to identify individual predictors of operative morbidity and mortality. RESULTS: The operative mortality in the series was 3.95%. This compared well with the p-POSSUM and APACHE predicted mortality of 4.31% and 4.29% respectively. Postoperative complications amounted to 45% with 24 (13.6%) patients having a major adverse event. On multrvariate analysis the pre-operative POSSUM physiological score (OR = 1.18, P = 0.009) was superior in predicting complications compared to the ASA (P= 0.108), APACHE (P= 0.117) or Childs classification (P= 0.136). In addition, serum sodium, creatinine, international normalized ratio (INR), pulse rate, and intra-operative blood loss were independent risk factors. A combination of the POSSUM variables and INR offered the optimal combination of risk factors for risk prognostication in HPB surgery. CONCLUSION: Morbidity for elective HPB surgery can be accurately predicted and applied in everyday surgical practice as an adjunct in the process of informed consent and for effective allocation of resources for intensive and high-dependency care facilities. 相似文献

Although the diagnostic and severity grading criteria on the 2013 Tokyo Guidelines (TG13) are used worldwide as the primary standard for management of acute cholangitis (AC), they need to be validated through implementation and assessment in actual clinical practice. Here, we conduct a systematic review of the literature to validate the TG13 diagnostic and severity grading criteria for AC and propose TG18 criteria. While there is little evidence evaluating the TG13 criteria, they were validated through a large‐scale case series study in Japan and Taiwan. Analyzing big data from this study confirmed that the diagnostic rate of AC based on the TG13 diagnostic criteria was higher than that based on the TG07 criteria, and that 30‐day mortality in patients with a higher severity based on the TG13 severity grading criteria was significantly higher. Furthermore, a comparison of patients treated with early or urgent biliary drainage versus patients not treated this way showed no difference in 30‐day mortality among patients with Grade I or Grade III AC, but significantly lower 30‐day mortality in patients with Grade II AC who were treated with early or urgent biliary drainage. This suggests that the TG13 severity grading criteria can be used to identify Grade II patients whose prognoses may be improved through biliary drainage. The TG13 severity grading criteria may therefore be useful as an indicator for biliary drainage as well as a predictive factor when assessing the patient's prognosis. The TG13 diagnostic and severity grading criteria for AC can provide results quickly, are minimally invasive for the patients, and are inexpensive. We recommend that the TG13 criteria be adopted in the TG18 guidelines and used as standard practice in the clinical setting.

Reoperative pancreaticoduodenectomy for periampullary carcinoma 总被引:4,自引:0,他引:4
Shukla PJ Qureshi SS Shrikhande SV Jagannath P Desouza LJ 《ANZ journal of surgery》2005,75(7):520-523
BACKGROUND: Potentially resectable periampullary tumours may not be treated appropriately due to lack of local expertise in both assessment of resectability and resection in referring centres. Tata Memorial Hospital is a major referral centre for oncology and these patients are finally referred to this institution. In carefully selected patients, resection can be accomplished. The purpose of the present paper was to determine the perioperative morbidity and mortality for patients undergoing reoperative pancreaticoduodenectomy at a major comprehensive cancer centre. METHODS: Between January 1991 and December 2001 15 patients, who had undergone previous non-resectional surgery for operable periampullary carcinoma, underwent re-exploration. The perioperative morbidity and mortality were analysed and compared with that of the group of patients undergoing primary pancreaticoduodenectomy (143 patients) in the same period. RESULTS: All the 15 patients undergoing re-exploration had a successful resection by pancreaticoduodenectomy. In the reoperative group eight patients (53%) underwent classic pancreaticoduodenectomy and seven patients (46%) had a pylorus-preserving pancreaticoduodenectomy, as compared to 102 (71%) and 41 (29%) patients in the primary surgery group, respectively. Although the mean operative time and the estimated blood loss were higher in the reoperative group, the morbidity and mortality rates were similar in the two groups. The overall 30-day mortality rate was 6.6% and 6.9% in the reoperative and the primary surgery group, respectively. Major morbidity occurred in two of the 15 patients (13.3%), and one patient (6.6%) died following surgery in the reoperative group. CONCLUSION: Reoperative pancreaticoduodenectomy can be performed safely in carefully selected patients with resectable, localized periampullary tumours with similar morbidity and mortality to patients undergoing primary surgery. 相似文献

Determinants of HAART discontinuation among injection drug users 总被引:2,自引:0,他引:2
The objective of this study was to identify psychosocial determinants of, and self-reported reasons for, HAART discontinuation among HIV-positive injection drug users (IDUs). We examined correlates between sociodemographic characteristics, drug use and risk behaviors, outcome expectations, adherence self-efficacy, social support and HAART discontinuation among 160 HIV-positive participants in the Vancouver Injection Drug Users' Study (VIDUS). Logistic regression was used to identify the factors independently associated with discontinuation of HAART. Seventy-one (44%) study participants discontinued HAART during the study period. Factors independently associated with discontinuation of HAART included recent incarceration (OR = 4.84, p = 0.022), negative outcome expectations (OR = 1.41, p = 0.001), adherence efficacy expectations (OR = 0.70, p = 0.003) and self-regulatory efficacy (OR = 0.86, p = 0.050). The most frequently cited reasons provided for discontinuing HAART were being in jail (44%) and medication side effects (41%). The results of this study suggest that psychological constructs derived from self-efficacy theory are highly germane to the understanding of HAART discontinuation behavior and interventions that may change it. Incarceration may result in interruptions in HAART among IDUs, and programmatic changes may be needed to promote optimal retention on HAART among incarcerated HIV-infected IDUs. 相似文献

BACKGROUND: Leaving the hospital against medical advice has been associated with increased morbidity and readmission. Factors associated with the risk of leaving against medical advice among HIV/AIDS patients or injection drug users have not been examined in detail. OBJECTIVES: To examine the clinical and social factors associated with leaving against medical advice (AMA) from a specialized HIV/AIDS ward among patients who reported a history of injection drug use. METHODS: All patients with a history of injection drug use admitted to the HIV/AIDS ward at St. Paul's Hospital, Vancouver, British Columbia (the largest specialized HIV/AIDS hospital ward in Canada) between April 1997 and October 2000 were reviewed retrospectively. A multivariate logistic regression model utilizing a generalized estimating equation algorithm identified factors associated with leaving the hospital AMA. RESULTS: Of the 1056 hospital admissions to the HIV/AIDS ward by patients with a history of injection drug use, 263 (24.9%) resulted in leaving the hospital AMA. Independent positive predictors of leaving AMA included recent injection drug use (adjusted odds ratio [AOR] = 2.08, 95% confidence interval [CI]: 1.41-3.07) and aboriginal ethnicity (AOR = 1.55, 95% CI: 1.05-2.28). Discharge AMA was also more likely to occur on weekends (AOR = 2.27, 95% CI: 1.49-3.48) and on days when social assistance payments were issued (AOR = 2.95, 95% CI: 1.70-5.10). Factors that independently reduced the odds of hospital discharge AMA included in-hospital methadone use (AOR = 0.49, 95% CI: 0.32-0.76), social support (AOR = 0.33, 95% CI: 0.21-0.51), and older age (per 10-year increment, AOR = 0.56, 95% CI: 0.43-0.73). CONCLUSIONS: Among HIV-positive patients with a history of injection drug use, the odds of leaving the hospital AMA were reduced for subjects who received inpatient methadone treatment, were of older age, or had social supports. Addiction treatment and interventions that enhance social supports in marginalized populations at risk for hospital discharge AMA should be further explored. 相似文献
