Abstract Background: The present study aims to assess the preliminary outcomes of the effectiveness of wrapping the ligamentum teres hepatis (LTH) around the gastroduodenal artery stump for the prevention of erosion hemorrhage after laparoscopic pancreaticoduodenectomy (LPD).Methods: We reviewed 247 patients who had undergone LPD between January 2016 and April 2019. The patients were divided into 2 groups according to whether LTH wrapped the stump of the gastroduodenal artery: group A (119 patients) who underwent the LTH wrapping procedure, and group B (128 patients) who did not undergo the procedure. The perioperative data from the two groups were reviewed to assess the effectiveness of the LTH procedure for the prevention of postpancreatectomy hemorrhage (PPH) and other complications.Results: No differences were observed in the clinical characteristics between the 2 groups. The data from 247 patients were acceptable for analysis: 119 patients underwent wrapping, and 128 patients did not. The incidence of clinically relevant pancreatic fistula (8.4% vs 3.9%), biliary fistula (2.5% vs 1.6%), intra-abdominal infection (10.1% vs 3.9%) and delayed gastric emptying (13.4% vs 16.4%) showed no significant difference between group A and group B. The 90-day mortality and 90-day reoperation rates (0.8% vs 0.8% and 5.0% vs 3.1%) were also similar between group A and group B. Furthermore, postpancreatectomy hemorrhage of Grade B and C occurred in 0 patients (0.0%) in the wrapping group, which was significantly less frequent than the occurrence in the nonwrapping group (7 patients; 5.5%, P=0.02).Conclusions: Wrapping the LTH around the gastroduodenal artery stump after LPD does not reduce the incidence of clinically relevant pancreatic fistula, biliary fistula or delayed gastric emptying. However, this procedure has a trend of reducing the rate of PPH of Grade B and C after LPD and is simple to perform.

PURPOSE: To assess the effects of Roux-en-Y jejunal limb length on gastric emptying and enterogastric reflux. METHODS: Seventy male Wistar rats were submitted to antrectomy with Roux-en-Y reconstruction and then were divided into two groups of 35 animals. Group A, short limb (7.5 cm) and Group B, standard limb (15 cm). Group A and B were subdivided into five subgroups each in order to study enterogastric reflux at 30 and 60 minutes and to evaluate gastric emptying at 5, 10 and 15 minutes. In order to measure gastric emptying and enterogastric reflux, radiotracers 99m Tc-Phytate and 99m Tc-DISIDA were respectively used. RESULTS: For gastric emptying, the radiotracer concentration was lower in Group A than in Group B after five minutes. The enterogastric reflux was present, but there were no significant differences between enterogastric reflux indexes concerning both A and B Groups. CONCLUSION: A standard Roux limb, besides being unable to protect the stomach from the enterogastric reflux, may become a functional barrier for gastric emptying.

Introduction: The perioperative morbidity following pancreas surgery remains high due to various specific complications: postoperative pancreatic fistula, postpancreatectomy hemorrhage, and delayed gastric emptying. The International Study Group of Pancreatic Surgery has defined these complications. The aim of this study is to evaluate the clinical applicability, to validate the International Study Group of Pancreatic Surgery definition, and to evaluate the postoperative morbidity. Methods: Between 2004 and 2014, 769 patients underwent resection. Data were collected in a prospective database. Univariate examination was performed using the χ2-test. Continuous data were tested with the Mann–Whitney U-test. Student’s t-tests and Fisher’s exact tests were performed. Results: A total of 542 patients were included in this study. In all, 91 (16.8%) patients developed postoperative pancreatic fistula, 69 of them clinically relevant grades B and C postoperative pancreatic fistula. Grades B and C postoperative pancreatic fistulas were significantly associated with a longer hospital stay. The postoperative pancreatic fistula grade significantly correlated with re-operation. Totally, 32 (5.9%) patients developed postpancreatectomy hemorrhage. Postpancreatectomy hemorrhage grade was significantly associated with re-operation and 30-day mortality. In all, 14 of 19 patients with grade C postpancreatectomy hemorrhage (73.7%) were re-operated; 3 had a simultaneous postoperative pancreatic fistula C. Grade B postpancreatectomy hemorrhage significantly prolonged hospital stay. Grade C postpancreatectomy hemorrhage significantly prolonged intensive care unit stay. Grade C postpancreatectomy hemorrhage led to longer intensive care unit stay but a shorter hospital stay. Delayed gastric emptying occurred in 131 (24.2%) patients. The delayed gastric emptying grade was significantly associated with re-operation. Nine of the re-operated patients had a simultaneous postoperative pancreatic fistula C. Grades A, B, and C delayed gastric emptying were associated with prolonged hospital- and intensive care unit stay. Conclusion: Delayed gastric emptying is the most common specific complication after pancreas resection, followed by postoperative pancreatic fistula and postpancreatectomy hemorrhage. The International Study Group of Pancreatic Surgery definitions are well applicable in clinical routine and the different grades correlate well with severity of clinical condition, length of hospital or intensive care unit stay, and mortality. Their widespread use can contribute to a more reproducible and reliable comparison of surgical outcomes in pancreas surgery.

Background: Morbidity following Pancreaticoduodenectomy still remains high. Few studies have shown decrease in morbidity with the addition of Braun Enteroenterostomy (BEE). Aim of the present study was to determine any possible benefit with addition of BE to the standard reconstruction after pancreaticoduodenectomy.Methods: In this prospective randomized controlled study, all patients who underwent Pancreaticoduodenectomy from June 2012 to July 2016 were included. They were randomized to undergo either standard reconstruction (Group A) or with addition of Braun Enteroenterostomy to standard reconstruction (Group B). Outcomes were compared between 2 groups and the results were analyzed. P value of <0.05 was considered significant.Results: 104 patients were included in the study. Group A included 56 patients who underwent standard reconstruction and Group B had 48 patients who had addition of BEE to standard reconstruction. The demographic profile, tumour characteristics, and biochemical profile were similar in 2 groups. Mean operating time and Intra operative blood loss were similar. The incidence of pancreatic fistula (POPF) did not differ significantly in 2 groups (14/56, 25% in group A versus 8/48, 16.6% in group B; p = 0.42). The incidence of Delayed Gastric Emptying (DGE) was not statistically different in 2 groups (20/56, 35.7% in group A versus 12/48, 25% in group B; p=0.77). Infection rates were similar in two groups. Mean hospital stay was similar in both groups (11.2 days versus 10.7 days; p=0.68).Conclusions: The outcomes of patients after pancreaticoduodenectomy were not altered by addition of Braun Enteroenterostomy to standard reconstruction.

e14717 Background: Laparoscopic pancreaticoduodenectomy (LPDE) has become increasingly popular in the world and now is considered to be a technically feasible and safe procedure for patients with tumors of the head of the pancreas and the periampullare area. At the same time, according to the literature data, a lot of surgeons stop performing totally laparoscopic pancreaticoduodenectomy (TLPDE) after 5 – 15 procedures because of the difficulties of learning curve. Aim of thew study: to evaluate the learning curve of totally laparoscopic pancreaticoduodenectomy. Methods: The data of 43 patients who were planed for LPDE during 5 year were analyzed. All the procedures were performed by one surgical team. 35 patients underwent totally laparoscopic pancreaticoduodenectomy (TLPDE). For 8 patients the procedures were palliative or converted. Patients were divided in three groups. Group A, B and C – 12;12;11 patients respectively. Operative time, intraoperative blood loss and the level of postoperative morbidity were examined. Results: Among the 43 patients, 35 patients underwent TLPDE. The conversion rate was in the group A - 33% (4 patients), group B – 33%(4 patients) and group C – no conversions. Mean operative time of TLPDE for the group A was - 542min; group B – 542min and group C less than 360min, minimally - 280). Mean blood loss was for group A - 683ml, group B – 612ml and group C 250ml. Total level of all kinds of postoperative morbidity was: group A - 66,5%, group B – 65,5% and group C – 36,0%. Postoperative mortality was: group A - 8,3%(one of the patients died from insufficiency of the pancreatojejenostomy, another – because of acute heart failure without any surgical complications); group B – 0% and group C - 0%. Conclusions: The results of TLPDE become significantly better after 25 procedures. The most difficult and potentially dangerous for intra and postoperative complications were: dissection along superior mesenteric and portal vein and suturing of pancreaticojejuno anastomosis. Performing TLPDE by the same team, including nurses, is a very important factor for quick learning curve and safety.

Abstract Background Biloma, an encapsulated collection of bile outside the biliary tree, supported by a predominantly iatrogenic biliary fistula, and bile likeage are two of the most important surgical complications after liver resection. We, hypothesized to conduct a project aimed to prevent, or reduce, the formation of biloma or biliary fistula applying on the hepatic resection area the cyanoacrylate glue (Glubran2). Methods We searched in our surgical database all patients underwent liver resection for mCRC from January 2013 to December 2018 and we found a total of 510 patients. 205 patients for Group A (study population: included patients in which we have used Glubran2 during surgical procedure) and 113 patients for Group B (control group), were enrolled. Results In both Groups no patients died during hospitalization and the 30-day mortality was 0 %. During follow-up in Group A, a biliary fistula was found in 2 patients (1 %) versus 3 patients in the Group B (2,6 %). In patients enrolled in Group A no adverse event were reported relate to the use of Glubran2. Conclusions It is possible to affirm that the use of Glubran2 as biliostatic agent after liver resection is useful to prevent bile leakage complication and biloma formation and its use demonstrated to be safe and feasible during liver surgery.

We have recently carried out a study of spermiogenic differentiation in two geographically isolated populations of Aphanius dispar (freshwater teleost), with a view to ascertaining variation at the ultrastructural level. The sampling areas were the Jebel Al Akhdar in the north (Group A) and the Dhofar region (Group B) in the south. Specimens from each group were collected, the testes removed, fixed in Karnovsky solution, post fixed in OsO, en bloc stained with uranyl acetate and then routinely processed to Agar 100 resin, semi and ultrathin sections were prepared for study.

Background: We compared one-year amputation and survival rates in patients fulfilling 1991 European consensus critical limb ischaemia (CLI) definition to those clas, sified as CLI by TASC II but not European consensus (EC) definition. Patients and methods: Patients were selected from the COPART cohort of hospitalized patients with peripheral occlusive arterial disease suffering from lower extremity rest pain or ulcer and who completed one-year follow-up. Ankle and toe systolic pressures and transcutaneous oxygen pressure were measured. The patients were classified into two groups: those who could benefit from revascularization and those who could not (medical group). Within these groups, patients were separated into those who had CLI according to the European consensus definition (EC + TASC II: group A if revascularization, group C if medical treatment) and those who had no CLI by the European definition but who had CLI according to the TASC II definition (TASC: group B if revascularization and D if medical treatment). Results: 471 patients were included in the study (236 in the surgical group, 235 in the medical group). There was no difference according to the CLI definition for survival or cardiovascular event-free survival. However, major amputations were more frequent in group A than in group B (25 vs 12 %, p = 0.046) and in group C than in group D (38 vs 20 %, p = 0.004). Conclusions: Major amputation is twice as frequent in patients with CLI according to the historical European consensus definition than in those classified to the TASC II definition but not the EC. Caution is required when comparing results of recent series to historical controls. The TASC II definition of CLI is too wide to compare patients from clinical trials so we suggest separating these patients into two different stages: permanent (TASC II but not EC definition) and critical ischaemia (TASC II and EC definition).

Abstract. Background: Absorbable sutures are not generally accepted by most vascular surgeons for the fear of breakage of the suture line and the risk of aneurysmal formation, except in cases of paediatric surgery or in case of infections. Aim of this study is to provide evidence of safety and efficacy of the use of absorbable suture materials in carotid surgery. Patients and methods: In an 11 year period, 1126 patients (659 male [58.5 %], 467 female [41.5 %], median age 72) underwent carotid endarterectomy for carotid stenosis by either conventional with primary closure (cCEA) or eversion (eCEA) techniques. Patients were randomised into two groups according to the type of suture material used. In Group A, absorbable suture material (polyglycolic acid) was used and in Group B non-absorbable suture material (polypropylene) was used. Primary end-point was to compare severe restenosis and aneurysmal formation rates between the two groups of patients. For statistical analysis only cases with a minimum period of follow-up of 12 months were considered. Results: A total of 868 surgical procedures were considered for data analysis. Median follow-up was 6 years (range 1-10 years). The rate of postoperative complications was better for group A for both cCEA and eCEA procedures: 3.5 % and 2.0 % for group A, respectively, and 11.8 % and 12.9 % for group B, respectively. Conclusions: In carotid surgery, the use of absorbable suture material seems to be safe and effective and with a general lower complications rate compared to the use of non-absorbable materials.
