Material și metode: Între anii 2006 și 2013, 297 pacienți (48 femei, 249 bărbați) cu vârste cuprinse între 18 și 77 ani au fost supuși intervenției chirurgicale laparoscopice pentru ulcer duodenal perforat, cu utilizarea a 3 (61%), 4 (29%) sau 5 (10%) trocare. Șaizeci și doi (21%) dintre pacienți au prezentat o formă ușoară, 190 (64,1%) au prezentat o formă moderată și 45 (14,9%) o formă severă de peritonită. Procedurile utilizate au fost: sutura simplă – 118 (39,8%) pacienți, sutura cu epiplonoplastie – 176 (59,5%), doar epiplonoplastie – 1 (0,3%) pacient, excizie și sutură – 1 (0,3%) pacient. Rezultate: Durata intervențiilor a fost între 30 și 120 minute, cu o medie de 65 minute. Mortalitatea a fost nulă. Complicații: infecții parietale – 3 (1%), fistule duodenale – 3 (1%), abcese abdominale – 2 (0,6%), hemoragii digestive – 1 (0,3%) și stenoza duodenală – 1 (0,3%). Durata medie de spitalizare – 5,5 zile. În comparație cu tehnica clasica, pacienții au necesitat mai puține analgetice și antibiotice, cu 80% mai puține pansamente și au avut cu 70% mai puține infecții parietale în evoluția postoperatorie. Concluzii: Tratamentul laparoscopic pentru ulcerul duodenal perforat, este recomandat chiar și în cazurile cu peritonită severă, evoluția postoperatorie fiind cu mai puține complicații și cu o recuperare mai rapidă fața de procedura clasică. Aceast abord poate fi considerat “standard de aur” în tratamentul ulcerului duodenal perforat.Introduction: This retrospective study evaluates results of the laparoscopic treatment of perforated duodenal ulcer obtained in 7 centers with experience in laparoscopic surgery from Romania. Material and methods: A total of 297 (48 women and 249 men) patients with perforated duodenal ulcer underwent laparoscopic intervention between 2006 and 2013, with ages 18 to 77 years. Three (61%), 4 (29%) or 5 (10%) trocars were used. In 62 patients (21%) was diagnosed mild form of peritonitis, in 190 (64.1%) – moderate and in 45 (14.9%) – severe peritonitis. Types of repair used in this study: simple suture – 118 (39.8%) patients, suture with omental patch – 176 (59.5%), only sutured omental patch – 1 (0.3%), excision and suture – 1 (0.3%) patient. Results: Operation time was between 30 and 120 min, with average of 65 min. Mortality rate was zero. Complications: parietal infections – 3 (1%), duodenal fistula – 3 (1%), intraabdominal abscesses – 2 (0.6%), digestive bleeding – 1 (0.3%) and duodenal stenosis – 1 (0.3%). Average length of hospital stay – 5.5 days. Patients treated using laparoscopic technique needed less analgesics, antibiotics, 80% less dressing procedures and had 70% less surgical site infections in comparison to traditional operation. Conclusions: Laparoscopic treatment of perforated duodenal ulcer can be recommended even for patients with severe peritonitis. This treatment is associated with fewer complications and more rapid recovery than traditional intervention. Laparoscopic repair can be considered “gold standard” in the treatment of perforated duodenal ulcer

Postoperative outcomes in oesophagectomy with trainee involvement

BACKGROUND: The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS: Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS: Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION: Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery

Can APACHE II, SOFA, ISS, and RTS Severity Scores be Used to Predict Septic Complications in Multiple Trauma Patients?

Background: Physiological composite scores are used to predict mortality in multiple trauma patients. Sepsis is the leading cause of late mortality in trauma victims brought about by immune suppression due to homeostasis dysregulation

Biological and Histological Assessment of the Hepatoportoenterostomy Role in Biliary Atresia as a Stand-Alone Procedure or as a Bridge toward Liver Transplantation

Background and objectives: In patients with biliary atresia (BA), hepatoportoenterostomy (HPE) is still a valuable therapeutic tool for prolonged survival or a safer transition to liver transplantation. The main focus today is towards efficient screening programs, a faster diagnostic, and prompt treatment. However, the limited information on BA pathophysiology makes valuable any experience in disease management. This study aimed to analyze the evolution and survival of patients with BA referred for HPE (Kasai operation) in our department. Materials and Methods: A retrospective analysis was performed on fourteen patients with BA, diagnosed in the pediatric department and further referred for HPE in our surgical department between 2010 and 2016. After HPE, the need for transplantation was assessed according to patients cytomegalovirus (CMV) status, and histological and biochemical analysis. Follow-up results at 1–4 years and long term survival were assessed. Results: Mean age at surgery was 70 days. Surgery in patients younger than 60 days was correlated with survival. Jaundice’s clearance rate at three months was 36%. Total and direct bilirubin values had a significant variation between patients with liver transplants and native liver (p = 0.02). CMV was positive in eight patients, half with transplant need and half with native liver survival. Smooth muscle actin (SMA) positivity was proof of advanced fibrosis. The overall survival rate was 79%, with 75% for native liver patients and an 83% survival rate for those with liver transplantation. Transplantation was performed in six patients (43%), with a mean of 10 months between HPE and transplantation. Transplanted patients had better survival. Complications were diagnosed in 63% of patients. The mean follow-up period was six years. Conclusions: HPE, even performed in advanced cirrhosis, allows a significant survival, and ensures an essential time gain for patients requiring liver transplantation. A younger age at surgery is correlated with a better outcome, despite early CMV infection

Effects of the radiofrequency interference with modified titanium surgical clips on liver parenchyma -an in vivo experiment

Rezumat Efectele interferenåei radiofrecvenåei cu agrafele de titan modificate la nivelul parenchimului hepatic -experiment in vivo Scop: Cercetarea testeazã biocompatibilitatea mai multor tipuri de agrafe de titan la nivelul ficatului în prezenåa radiofrecvenåei, în funcåie de distanåa plasãrii agrafei şi timp. Material aei metodã: Este un studiu experimental pe porc care urmãreaete modificãrile histologice (inflamaåie, necrozã, fibrozã) ce apar la interfaåa dintre agrafele de Ti (modificate prin tratare termicã în vid la temperaturi înalte -1000°C aei 1150°C) şi ficat, în condiåiile prezenåei radiofrecvenåei. Agrafele au fost plasate la nivelul ficatului de porc la distanåa de 0.5 cm, 1,5 cm aei 2,5 cm faåa de sonda de RF. Inflamaåia, necroza şi firboza au fost mãsurate la 7, 14 şi 28 de zile. Rezultate: Alterarea tisularã scade odatã cu creaeterea distanåei la care au fost implantate agrafele. Necroza şi inflamaåia induse de radiofrecvenåã în åesuturile din jurul agrafelor de titan implantate se diminueazã în timp, dar fibroza nu devine mai pronunåatã. Agrafele de titan modificate la 1000°C duc la o necrozã mai puåin pronunåatã decât agrafele de titan nemodificate. Efectele nu se menåin însã pentru inflamaåie sau fibrozã. Tipul de agrafã modereazã efectul distanåei asupra fibrozei şi necrozei. Tipul de agrafã modereazã relaåia timpinflamaåie. Concluzii: Datele obåinute sugereazã cã nu existã un singur tip de agrafe de titan care prezintã o biocompatibilitate net superioarã celorlalte în toate situaåiile. Biocompatibilitatea agrafelor de titan depinde de distanåa la care sunt acestea amplasate: cele netratate mai aproape (sub 1cm faåã de sonda de RF), cele tratate termic mai departe (>1cm). Cuvinte cheie: Agrafe de titan, radiofrecvenåa, inflamaåie, necrozã, fibrozã Abstract Aim: This study sets out to test the biocompatibility of titanium clips in liver, in the presence of radiofrequency. Biocompatibility is assessed at various distances from the RF electrode and different points in time. Method: It is an experimental study conducted on pigs and makes use of histological changes that occur at the livertitanium interface in presence of RF to test hypotheses. The titanium clips were modified in high vacuum (10 -5 atm) by heating them at 1000 °C aei 1150 °C. Titanium clips were placed in liver at 0.5, 1.5 and 2.5 cm from RF probe. At 7, 14 and 28 days the inflammation, necrosis and fibrosis were assessed. Results: The histological alterations decrease with the distance of implantation of titanium clips. The inflammation and necrosis nearby the titanium clips decrease in time, but the fibrosis does not increased, as expected. The modified titanium at 1000°C clips cause less necrosis than commercial titanium clips. The moderator role of clip type between distance and cell alteration is empirically supported only for fibrosis and necrosis. The moderator role between time and cell alteration is supported only for inflammation. surgical clips in all situations. The biocompatibility of the titanium clips depends on the distance from the RF probe. The commercial ones prove less damaging if they are placed close to the RF probe (less than 1 cm) and those that were treated at 1150 C have a better bio-compatibility if placed more than 1 cm from RF probe
