Incidental diagnosis of a pancreatic adenocarcinoma in a woman affected by gestational diabetes mellitus: case report and literature review.

Pancreatic cancer is rarely diagnosed during pregnancy; it usually manifests with symptoms such as epigastric pain, vomiting, weight loss, and jaundice, rarely mimicking the hemolysis, elevated liver enzymes, and low platelet count syndrome. It has been postulated that there exists a correlation between the diagnosis of gestational diabetes mellitus and the occurrence of pancreatic cancer later in life. We conducted an expert literature review of the 31 available documented pancreatic cancer cases that were diagnosed during pregnancy. We also report pancreatic adenocarcinoma incidentally suspected in an asymptomatic woman affected by gestational diabetes mellitus; the woman was undergoing a fetal growth scan.

Liver resection for metastases from colorectal cancer in very elderly patients: New surgical horizons.

INTRODUCTION AND AIM: Patients with colorectal cancer (CRC) may develop liver metastases. Surgical resection remains the best treatment of choice for colorectal liver metastases (CRLM) according to resectability criteria, with a long-term survival of 25% up to 41% after 5 years. Advanced age is associated with a higher incidence and co-morbidity, particularly cardiovascular disease, as well as deteriorating physiological reserves. The aim of this study was to analyse the overall and disease-free survival for patients with CRLM according to their chronological age. METHODS: Patients with CRLM were enrolled in the study. Data on gender, age, co-morbidity, metastasis characteristics (number, size and total metastatic volume (TMV)), use of perioperative chemotherapy and operative and post-operative complications were collected. Then, according to recent World Health Organization (WHO) guidelines, the patients were grouped by age. Statistical analysis was performed using the software R (ver. 2.14.1). RESULTS: Hepatic resection was performed in 149 patients (21 patients in the very elderly group, 79 in the elderly group and 49 in the younger group). The three groups were comparable in terms of operative duration, transfusion rate, length of high-dependency unit (HDU) stay and post-operative hospital stay. The very elderly group showed a non-significant increase in post-operative morbidity. The 30-day and 60-day/inpatient mortality rates increased with age without any significant statistically difference between the three groups (very elderly group 4.8% and 4.8%; elderly group: 2.5% and 3.8%; and younger group 0% and 2%). At 5 years, the overall survival was 28.6% for very elderly patients (≥75 years), 33.3% for elderly patients (≥65 to <75 years) and 43.5% for younger patients (≤65 years). The 1-, 3- and 5-year disease-free survival was similar across the groups. CONCLUSIONS: Liver resection for CRLM in carefully selected patients above the age of 75 can be performed with acceptable morbidity and mortality rates, similar to those in younger patients. Moreover, the severity of CRLM in elderly patients is proven to be lesser than in younger patients. Thus, we can conclude that advanced chronological age cannot be considered a contraindication to hepatic resection for CRLM.

Resection of hepatocellular carcinoma in elderly patients and the role of energy balance.

INTRODUCTION: Progressive functional impairment with age has a significant impact on perioperative risk management. Chronic liver diseases induce a strong oxidative stress; in the elderly, in particular, impaired elimination of free radicals leads to insufficient DNA repair. The events associated with a weak response to growth factors after hepatectomy leads to a decline in liver regeneration. Hypercholesterolemia is highly prevalent in the elderly, which may alter the coenzyme Q10 (CoQ) levels and in turn the cellular energy balance. This condition is commonly treated with statins. The aim of this study is to investigate the role of preoperative cellular energy balance in predicting hepatocellular carcinoma (HCC) postresection outcomes. MATERIALS AND METHODS: In a 5-year period (2009-2013), elderly patients with hypercholesterolemia, cardiovascular disease, and diabetes mellitus, undergoing HCC resection, were recruited and grouped by age (<75 and ≥ 75 years old). All patients were previously treated with statins. The risk factors associated with hospital morbidity/mortality and prolonged length of stay (LOS) were evaluated. RESULTS: Forty-five elderly patients were recruited and grouped according to their treatment: Group 1 (n = 23) was treated with statins alone (control group), whereas Group 2 (n = 22) was treated with statins and a CoQ analogue, 3 weeks from the surgery and at least a month later (experimental group). The majority of our patients were treated with atorvastatin [n = 28 (53.84%)] and the minority with simvastatin [n = 17 (32.69%)], 20 mg/day, for at least 3 years before the surgery. Perioperative mortality was observed in one patient of Group 1 (4.3%). Morbidities were noted in 13 patients of Group 1 (56.5%) and four patients of Group 2 (18.2%). The control group showed delayed functional recovery, muscle weakness, increased infection rate, and pleural effusion due to prolonged bed rest (hospital stay 13 days (7-19) vs. 8.5 days (5-12)), compared with the experimental group. The overall survival at 5 years was similar for both groups (n = 10 patients (43%) in Group 1 vs. n = 10 patients (45%) in Group 2). CONCLUSION: In the elderly population, survival is closely linked to postoperative morbidity and mortality. In our study, prolonged LOS was found to be related to delayed bioenergetic recovery. When limited, risk factors such as infections, neutropenia, and red blood cell transfusions could lower LOS and mortality of elderly patients with HCC. Higher age was associated with greater postoperative morbidity and successful hospital stay.

Seven-year survival after pancreaticoduodenectomy for early recurrent renal cell carcinoma involving the duodenum A case report.

UNLABELLED: RCC has a range of clinical manifestations including vague abdominal symptoms, haematuria, flank pain and a palpable abdominal mass. Generally, 25-30% of patients are found to have metastases at diagnosis but a further 30-50% of patients with local disease will develop metastases during the course of their illness. Spread in RCC is lymphatic, haematogenous, transcoelomic or by direct invasion and the most common sites of metastasis in RCC are the lung, lymph nodes, bones and liver. Metastasis to the small intestine is rare and the duodenum is the segment least often affected. RCC metastasis to the duodenum occurs most commonly in the periampullary region, followed by the bulband usually manifest as gastrointestinal bleeding or obstruction. Bleeding may be the first symptom of metastatic disease in patients who have previously undergone nephrectomy for RCC. Survival is better for patients with localized disease compared with those with regional and distant metastases. This report describes a case of duodenal metastasis from RCC in which the patient presented with upper gastrointestinal bleeding and duodenal obstruction and was treated with pancreaticoduodenectomy with an excellent long-term outcome. Long-term survival was better than survival data reported in the current literature. . KEY WORDS: Duodenal metastasis, Gastrointestinal bleeding, Renal cell carcinoma, Pancreaticoduodenectomy.

Partial portal vein arterialization in acute liver failure.

Experimental studies have shown that increasing the oxygen supply to the liver through partial portal vein arterialization (PPVA) enhances liver regeneration after extensive liver resection or drug intoxication. In the last two decades, several PPVA procedures were performed in humans with the aim to prevent or treat acute liver failure (ALF) following major hepatobiliary surgery or other etiology. The aim of this review was to analyze literature data on PPVA and report our experimental and clinical experience of this procedure. In this setting, we report our positive experience in the realization and clinical application of an extracorporeal device able to increase the oxygenated blood delivered to the liver through the umbilical vein and to support liver function in a man subjected to an extended liver resection. PPVA procedure has shown promising results in the treatment of ALF following major hepatobiliary surgery or from other etiology. Moreover, less invasive approaches to PPVA demonstrated to be safe and efficacy. It is clear that further investigations must be done to fully understand the potentiality of PPVA as a strategy to treat ALF.
