An Attempt to Build a National Prospective Electronic Database for Pancreaticoduodenectomies in Romania - Preliminary Results of the First Year Enrollment.

Introduction: National databases for pancreaticoduodenectomies (PD) have contributed to better postoperative outcomes after such complex surgical procedure because the multicentre collection of data allowed more reliable analyses with quality assessment and further improvement of technical issues and perioperative management. The current practice and outcomes after PD are poorly known in Romania because there was no national database for these patients. Thus, in 2016 a national-intent electronic registry for PD was proposed for all Romanian surgical centers. The study aims to present the preliminary results of this national-intent registry for PD after one-year enrollment. Patients Methods: The database was started on October 1st, 2016. Data were prospectively collected with an electronic online form including 102 items for each patient. The registry was opened to all the Departments of Surgery from Romania performing PD, with no restriction. Results: During the first year of enrollment were collected the data of 181 patients with PD performed by 24 surgeons from four surgical centers. The age of patients was 64 years (28 - 81 years), with slightly male predominance (61.3%). Computed tomography was the main preoperative imaging investigation (84.5%). All the PDs were performed by an open approach. The Whipple technique was used in 53% of patients, and a venous resection was required in 14.3% of cases. A posterior approach PD was considered in 16.6% of patients. The stomach was used to treat the distal remnant pancreas in 50.1% of patients. The operative time was 285 min (110 - 615 min), and the estimated blood loss was 400 ml (80 - 3000 ml). The overall morbidity rate was 55.8%, with severe (i.e., grade III-IV Dindo-Clavien) morbidity rate of 10%, and 3.9% in-hospital mortality rate. The overall pancreatic fistula, delayed gastric emptying and hemorrhage rates were 19.9%, 39.8% and 15.5%. Periampullary malignancies were the main indications for PD (78.9%), with pancreatic cancer on the top (48%). Conclusions: To build a prospective electronic online database for PD in Romania appears to be a feasible project and a useful tool to know the current practice and outcomes after PD in our country. However, improvements are still required to encourage a larger number of surgical centers to introduce the data of patients with PD.

A Seroprevalence Study of Hepatitis B and C Virus Infections in a Hospitalized Population in Romania, an Opportunity for a Better National Prevention and Control Strategy.

BACKGROUND AND AIMS: The most recent prevalence data for hepatitis B virus (HBV) infection in Romania came from an ESEN 2 study (2002), and from a Romanian population-based study performed in 2008. Most of the previous studies were regional and performed in specific groups (blood donors, pregnant women, institutionalized people, etc) and had limited representativeness at the national level, both for HBV and hepatitis C virus (HCV) infection. The scarcity of prevalence data for HBV and HCV infection coming from the routine surveillance was also considered. The aim of our study was to obtain overall and age group specific estimates of the prevalence of HBV and HCV infections markers in Romania, in order to recommend evidence-based public health interventions. The main outcome was the proportion of persons with HBV, HCV and HBV+HCV infection markers, overall and by age group and gender. METHODS: Our seroprevalence study ensured national representativeness for the targeted hospitalized population. A prospective collection of serum samples in hospital laboratories was completed between September and November 2013, using a systematic sampling. The study respected the confidentiality of personal data. We calculated the sample size using EpiInfo7 and used Z test - Two-tailed probability for statistical significance. RESULTS: The overall prevalence data estimated in our study were HBc Ab 28%, HBs Ag 4.2%, HBs Ab regardless of titer 64.1%, HBs Ab in titer of at least 10 mUI/ml and negative HBc Ab 17.5%; HCV Ab 5.6%; HBc Ab and HCV Ab 2.8%, as markers of double infection. CONCLUSION: The overall prevalence data estimated in our study for HBs Ag (4.2%) and HCV Ab (5.6%) correspond to a medium endemicity based on the WHO criteria. The estimated prevalence of HBV and HCV infection markers in the study population should represent an opportunity for a better national prevention and control strategy.

Ultrasound aspect of mesenteric panniculitis. Case report.

Mesenteric panniculitis represents a cronic inflammation of the adipose tissue of the mesentery which can present sometimes with the imagistic aspect of one or multiples pseudotumors. We present the case of female patient in which mesenteric panniculitis was found accidentally during a routine abdominal ultrasound examination leading to differential diagnostics problems. Color Doppler and contrast enhancement ultrasonography were helpful for diagnosis evidencing a benign circulatory signal.

Staging laparoscopy in digestive cancers.

BACKGROUND. Laparoscopy and laparoscopic ultrasonography may assist in the more accurate staging of digestive cancers. We assessed the diagnostic value of staging laparoscopy in patients with cancers of lower esophagus, stomach, liver, biliary tract, pancreas and colon. MATERIAL AND METHOD. Extended staging laparoscopy, laparoscopic ultrasonography and peritoneal cytology were performed in 165 patients with primary digestive cancers, admitted between January 2006 and December 2008 at three tertiary referral hospitals participating in the study. Staging laparoscopy was immediately followed by open surgery in 63 patients without distant metastases or with uncertain primary tumor resectability, and in 20 colorectal cancer patients with resectable hepatic metastases. The sensibility, sensitivity and diagnostic accuracy of staging laparoscopy for distant metastases and tumor resectability were assessed against the findings on open surgery and the final pathological report. RESULTS. An unnecessary laparotomy was avoided in 36 of the 99 patients (36.4%) without distant metastases on imaging pre-therapeutic staging. The staging laparoscopy sensitivity for distant metastases varied between 66% and 100% and the diagnostic accuracy between 87% for the lower esophageal cancer and 100% for the biliary tract tumors. The overall morbidity of staging laparoscopy was 2.5% and the mortality 0. CONCLUSION. Staging laparoscopy avoids unnecessary laparotomies and changes the therapeutic plan in a significant number of patients. It can be performed just before the planned surgery or as a separate diagnostic procedure. The laparoscopy indications in digestive cancers are changing fast, with ongoing new developments in cancer treatment and laparoscopic technology.

Minimally invasive esophagectomy by video-assisted thoracoscopic approach for esophageal carcinoma. A case report.

Esophageal carcinoma represents a pathological entity with a bad prognosis even if adequate multimodal treatment is applied. Because of the high operative morbidity and mortality, due especially to respiratory and infectious complications, the tendency nowadays is to mobilize the thoracic esophagus and to perform esophagectomy and mediastinal lymphadenectomy by thoracoscopy instead of thoracotomy. We present the case of a 55-year-old male patient who was diagnosed with a mediothoracic esophageal spinocellular carcinoma, in whom we successfully performed subtotal esophagectomy by cervico-thoraco-abdominal approach, the dissection of the thoracic esophagus being performed entirely by thoracoscopy.

Evaluation of viral replication in children with chronic hepatitis B with and without interferon treatment.

BACKGROUND: In chronic infection with hepatitis virus B the fact that HBeAg becomes negative does not always mean suppression of viral replication. METHOD: HBV replication was assessed in 74 patients with chronic hepatitis or viral B cirrhosis, in whom diagnosis was made according to clinical, biological, and histological criteria. The patients were divided into two groups: group I (36 patients with interferon- therapy, 3 million U/m 2/ dose, 3 doses/week over a period of 4-6 months) and group II (control group of 38 patients who did not undergo interferon therapy). After a follow up period of 6 years in which patients underwent clinical, biochemical and serologic monitorization, HBV DNA was detected by the hybridization method on solid medium. RESULTS: During evolution the levels of transaminases became normal in both groups. The HBe Ag/Ab seroconversion rate at the end of the interferon therapy was 52.8% and the spontaneous HBe Ag/Ab seroconversion rate was 72.7% in group II after an average evolution of 6 years. HBs Ag/Ab seroconversion was not detected in any patient. Assessment of viral replication by HBV DNA testing at the end of the follow up period showed higher levels as compared to the HBeAg testing (69.4% vs. 25% in group I, 55.2% vs. 7.9% in group II). The absence of viral replication (HBV DNA negative) had similar rates in both groups (30.6% in group I vs. 44.8% in group II, p>0.9) and HBV DNA titers in the two groups were not significantly different at the end of the follow up period. In both groups, HBV DNA titers were significantly higher in patients with positive HBeAg. The concordance between the two viral markers was 100%. CONCLUSION: Because of the fluctuating evolution, long-term follow up and monitorization (including HBV DNA testing) of patients with chronic hepatitis B and of inactive HBsAg carriers are necessary.

Incidents and postoperative complications of laparoscopic cholecystectomies for acute cholecystitis.

The purpose of this study was to analyze incidents and postoperative complications of the laparoscopic cholecystectomies performed for acute cholecystitis in 1453 patients in the 3rd Surgical Clinic, Cluj-Napoca. Hemorrhage occurred in 139 (9.5%) cases from which 75 (54%) lesions of the cystic artery, 63 (45.3%) cases of bleeding from the vesicular bed and 1 patient (0.72%) with section of the hepatic artery. Lesions of the bile ducts occurred in 13 (0.9%) patients from which 4 (3.07%) were on the right hepatic duct and 9 (6.93%) on the common bile duct. We encountered 152 (10.46%) early postoperative complications from which 92 (60.5%) were grade I, 56 (37%) grade II, 0 grade III and 4 (2.63%) grade IV, according to Clavien's classification. There were 35 (2.4%) nonspecific postoperative complications from which there where phlebitic reactions in 25 (71.4%) patients, phlebitis in 9 (25.7%) and upper digestive hemorrhage due to acutization of a duodenal ulcer in 1 patient (2.9%). We also registered a number of 20 (1.38%) later postoperative complications: 10 (50%) residual biliary lithiasis in the first postoperative year, and 10 (50%) hernias at the umbilical trocar insertion site.

Splenic abscesses.

Splenic abscesses are rare entities (autopsy incidence between 0.14-0.7%). The most frequent etiology is the septic emboli seeding from bacterial endocarditis (about 20% of cases) or other septic foci (typhoid fever, malaria, urinary tract infections, osteomielitis, otitis). The treatment of splenic abscesses was until recently splenectomy with antibiotherapy. The actual trends are more conservative (mini invasive or non-invasive) because the immunologic role of the spleen has been better understood over the last year
