LOW MORTALITY RATE IN 97 CONSECUTIVE PANCREATICODUODENECTOMIES: the experience of a group

Context Pancreaticoduodenectomy is the procedure of choice for resectable cancer of the periampullary region. These tumors account for 4% of deaths from cancer, being referred to as one of the lowest survival rates at 5 years. Surgery remains a complex procedure with substantial morbidity and mortality. Despite reports of up to 30% mortality rates, in centers of excellence it have been identified as less than 5%. Recent studies show that pancreaticojejunostomy represents the “Achilles’ heel” of the procedure. Objective To evaluate the post-operative 30 days morbidity and mortality rates. Methods Retrospective analysis of 97 consecutive resected patients between July, 2000 and December, 2012. All patients were managed by the same group, and data were obtained from specific database service. The main objective was to evaluate the 30-day mortality rate, but we also studied data of surgical specimen, need for vascular resection and postoperative complications (gastric stasis, pancreatic fistula, pneumonia and reoperation rate). Results Thirty-day mortality rate was 2.1% (two patients). Complete resection with no microscopic residual tumor was obtained in 93.8% of patients, and in 67.3% of cases pathology did not detected metastatic nodes. Among postoperative complications were reported 6% of prolonged gastric stasis, 10.3% of pneumonia, 10.3% of pancreatic fistula and 1% of infection in the drain pathway. Two patients underwent reoperation due to bleeding and infected hematoma caused by pancreatic fistula, and another for intestinal obstruction because of adhesions at postoperative day 12. Conclusions The pancreaticoduodenectomy as treatment procedure for periampullary cancers has a low morbidity and mortality rate in services with experience in Hepato-Pancreato-Biliary surgery, remaining as first-line treatment in resectable patients

Spontaneous rupture of giant hepatic hemangioma: a case report and review of literature.

O hemangioma é o tumor benigno mais comum do fígado,  sua frequência varia de 0,5 a 7% em autopsias. Tumores maiores que 5 cm são chamados de hemangiomas gigantes. Ruptura é uma complicação muito rara, apesar de ser a mais severa. Nós reportamos o caso de um paciente de 52 anos que se apresentou com hemangioma hepático gigante roto e foi tratado por cirurgia em dois tempos com bom resultado

AMBULATORY LAPAROSCOPIC CHOLECYSTECTOMY IS SAFE AND COST-EFFECTIVE: a Brazilian single center experience

ABSTRACT Background - Laparoscopic cholecystectomy is the treatment of choice for gallstone disease, and has been perfomed as an outpatient surgery in many Institutions over the last few years. Objective - This is a retrospective study of a single center in Brazil, that aims to analyze the outcomes of 200 cases of ambulatory laparoscopic cholecystectomy performed by the same Hepato-Pancreato-Biliary team, evaluating the safety and cost-effectiveness of the method. Methods - Two hundred consecutive patients who underwent elective laparoscopic cholecystectomy were retrospectively analyzed; some of them underwent additional procedures, as liver biopsies and abdominal hernias repair. Results - From a total of 200 cases, the outpatient surgery protocol could not be carried out in 22 (11%). Twenty one (95.5%) patients remained hospitalized for 1 day and 1 (4.5%) patient remained hospitalized for 2 days. From the 178 patients who underwent ambulatory laparoscopic cholecystectomy, 3 (1.7 %) patients returned to the emergency room before the review appointment. Hospital cost was on average 35% lower for the ambulatory group. Conclusion - With appropriate selection criteria, ambulatory laparoscopic cholecystectomy is feasible, safe and effective; readmission rate is low, as well as complications related to the method. Cost savings and patient satisfaction support its adoption. Other studies are necessary to recommend this procedure as standard practice in Brazil

EARLY DRAIN FLUID AMYLASE IS USEFUL TO PREDICT PANCREATIC FISTULA AFTER PANCREATODUODENECTOMY: LESSONS LEARNED FROM A SOUTHERN BRAZILIAN CENTER

ABSTRACT BACKGROUND: Pancreatic fistula represents the most feared complication after pancreatoduodenectomies, being the major responsible for the high morbidity and mortality after this operation. Its incidence remains around 10% to 30%. In recent years, several authors have studied the value of amylase in abdominal drains fluid, measured at an early stage after the surgical procedure, as a useful tool to identify patients at risk of developing pancreatic fistula. OBJECTIVE: To analyze the value of early drain fluid amylase as a method to predict the occurrence and severity of postoperative pancreatic fistula in patients undergoing pancreatoduodenectomies. METHODS: We evaluated 102 prospective patients submitted to pancreatoduodenectomies from January 2013 to June 2017. The mensuration of amylase in abdominal drains was performed on days 1, 3, 5 and 7 in all patients. Patients were divided into three groups according to postoperative day 1 (POD1) results: values 5.000 U/L (group 3). RESULTS: The incidence of pancreatic fistula was 25.5%, being 3.33%, 27.3% and 41.02% in the three groups, respectively. Compared with group 1, the risk of developing pancreatic fistula increased with increasing amylase values on POD1. Amylase values on POD1 and POD3 of patients with pancreatic fistula were higher than in the other ones without this complication (P<0.001). In addition, in group 3, 37.5% of patients with pancreatic fistula evolved to death (P<0.001). Finally, in this group, patients who died had drain fluid amylase values on POD1 significantly higher than the others in the same group (P<0.001). CONCLUSION: Early drain fluid amylase value is a useful test to stratify patients in relation to the risk of developing pancreatic fistula after pancreatoduodenectomies, in addition to correlate with the severity of this complication

ASSOCIATION BETWEEN MURINE DOUBLE MINUTE 2 - T309G polymorphism and recurrence of hepatocellular carcinoma after surgical treatment

Background - Discovery and incorporation of biomarker panels to cancer studies enabled the understanding of genetic variation and its interference in carcinogenesis at molecular level. The potential association between single nucleotide polymorphism (SNP) 309 and increased development of tumors, such as hepatocellular carcinoma, has been subject to several studies. This is the first study on this association conducted in Brazil. Methods - 62 cases of cirrhotic patients with hepatocellular carcinoma surgically treated by partial hepatectomy (HPT) or by liver transplantation (LTX) from 2000 to 2009 at Santa Casa Hospital Complex, in the city of Porto Alegre, were retrospectively analyzed. Tumor samples from surgical specimen were collected and prepared for study in paraffin blocks. Results - Overall survival was 26.7 months in the HPT group and 62.4 months in the LTX group (P <0.01). Overall tumor recurrence was 66.7% in the HPT group (10/15) and 17% in the LTX group (8/47) (X²=13.602, P <0.01). Alpha-fetoprotein levels >200ng/mL, microvascular invasion and histological grade were associated with tumor recurrence (P <0.01). Recurrence rates in each surgical group and analysis of factors associated with tumor recurrence, when stratified for each genotypic pattern, were both not statistically significant. Conclusion - G/G genotype was not associated with tumor recurrence after surgical treatment and it did not show any correlation with other prognostic factors
