[Early results of the surgical management of gastrointestinal stromal tumors (gist)--the experience of the 3rd surgical unit]. / Rezultate imediate in managementul chirurgical al tumorilor stromale gastrointestinale primare (gist)-- experienta clinicii a III-A chirurgicale.

UNLABELLED: This study provides a clinical and paraclinical algorithm of assessment of gastrointestinal stromal tumors (GIST), with the possibilities and limits of their current management. It is focused on defining an optimal imaging and anatomoclinic diagnosis protocol. In the absence of specific algorithm of surgical management, the study proposes an evaluation of possible histologic diagnosis and the indication for surgery, and the assessing the immediate results of thesurgical treatment. MATERIALS AND METHODS: A retrospective analysis was carried out over a period of 8 years (2004-2011), including patients with pathologic results of resection specimens revealing the stromal nature. There were analyzed the tumor characteri stics, the association with other digestive tumors, the biologic behavior, clinical manifestations and the comorbidities of the patient, the indication for surgery, and also, the surgical morbidity and mortality. From 2004 to 2011 there have been operated 24 cases of GIST diagnosed histologically by common stains. Among them, a total of 16 patients (beginning with 2007) were confirmed immunohistochemicaly. RESULTS: During the study, each clinical suspicion of GIST was an opportunity for thorough assessment of the clinical picture, imaging studies or anatomoclinical aspects (intraoperative macroscopical aspects, pathological and immunhistochemical examination). We have tried a standardization of diagnostic and therapeutic algorithm. Positive diagnosis of GIST was clinicaly suspected in patients with digestive tract tumors (22 cases out of 24) without mucosal involvement, or based on intraoperative macroscopic appearance. The lesions were confirmed by the pathologist. The surgical morbidity (4 cases--16.6%), was to the surgery (a single case of anastomotic leakage) or due to patient's comorbidities (diabetus, chronic renal failure, etc), and has been framed to acceptable extent. No deaths occurred in relation to the surgery. CONCLUSIONS: The diagnostic difficulties are overcome in terms of a positive laboratory features revealed by immunhistochemical examination. The surgical approach of GIST is different from that of a carcinoma. The postoperative immunhistochemical confirmation of GIST, leads the patient to a specific adjuvant treatment.

[Rare clinical situatons of the diverticuli of the colon]. / Situatii clinice rare ale diverticulilor colonului.

UNLABELLED: It is well known that the diverticuli of the colon gets inflamed in 10-15% of cases, thus becoming clinical symptomatic as a diverticulitis, while in other 15% they will bleed, with the clinical aspect of an inferior digestive bleeding. Our study presents some clinical observations with diverticuli of the colon, that raised diagnostic and therapeutic problems. MATERIAL AND METHOD: Between 2001-2010, 17 patients were admitted in the 3rd Surgery Clinic, University Hospital "St.Spiridon", Iasi, with asymptomatic diverticuli of the colon, that were put in evidence imagistically, intraoperative or on specimens after removal of the colon for other conditions;meanwhile, there were 15 patients admitted with complications of the diverticuli:5 patients had perforated diverticulitis (4-pericolic abscesses and one with peritonitis in the lower abdomen), 4 had rectal bleeding and the other 6 raised particular problems of diagnostic and treatment, being included in the present study. RESULTS: Five out of six underwent operation. One patient refused the surgical treatment. Postoperative evolution was favorable in 4 out of the 5 operated patients. CONCLUSIONS: The complications of colonic diverticuli present on admission under clinical aspects that usually mimic a colonic cancer. In these situations the imagistic examinations do not offer enough details to elucidate the diagnosis. Our six particular observations strengthen the dictum of avoiding the "mirage" of the first lesion. The extent of the surgical procedure in the case of patients with colonic diverticuli admitted under the clinical aspect of a complication is sometimes disproportionate and encumbered of increased mortality and complication rate.

[Classification and staging systems for hilar cholangio-carcinoma (Klatskin tumors): clinical application and practical relevance]. / Sisteme de clasificare si stadializare pentru colangio- carcinomul hilar (tumora Klatskin): aplicatie clinica si relevanta practica.

Hilar cholangiocarcinomas or Klatskin tumors have been classified in 1975 by French surgeons Henri Bismuth and Marvin B. Corlette and this remains largely used in clinical practice. The authors present the TNM classification and the changes introduced by the sixth and seventh edition of Union for International Cancer Control regarding the tumors of the proximal bile duct and describe Blumgart classification for tumors of this site. The usefulness of these systems is assessed considering the last six years experience of the service.

[Amyand hernia--a rare anatomic and clinical entity diagnosed intraoperatively]. / Hernia amyand--o entitate anatomoclinica rara diagnosticata intraoperator.

The Amyand hernia is an uncommon variant of the inguinal hernia, rarely recognised before the surgical treatment because of the confusion with a strangled hernia. In spite of this, the clinical presentation seems to follow a well determined pathway, so it is possible to state that the uncorrect diagnosis is to be attributed to the ignorance of this variant of hernia. We present two consecutive case reports of acute appendicitis founded in an inguinal hernia sac. The clinical presentation depended on the inflammation extension inside the hernia sac and the presence or not of peritoneal contamination. The patients were admitted for a painful pseudotumor in the inguinal region with irreducibility, mimicking strangled inguinal hernia with acute inflammatory syndrome. Intraoperatively we have found a hernia sac with a phlegmonous/gangrenous appendix inside. Appendectomy was performed, followed by hernioplasty (retrofunicular technique) without prosthetic material). The operation followings were favorable. We conclude that amyand hernia must be considered as differential diagnosis of apparently strangled inguinal hernias. Technical precautions and antibioprophylaxy applied during surgery may prevent septic complications after hernioplasty. The hernia repair must be performed without prosthetic material and using exclusively resorbable sutures.

[Pancreaticoduodenectomy for pancreatic head cancer, 54 cases]. / Duodenopancreatectomia cefalica in cancerul de cap de pancreas--consideratii asupra 54 cazuri.

UNLABELLED: Pancreatic cancer has an increase rate in western countries. From the first pancreaticoduodenectomy (PD) performed by Kausch in 1909, the value of the resection in the treatment of pancreatic head cancer was disputed. AIM: To assess the PD with or without pylorus preservation as surgical treatment for pancreatic cancer. METHODS: Retrospective review of the clinical records of patients undergoing PD for pancreatic cancer. RESULTS: From January 1995 till December 2005, in the First and Third Surgical Units, "St. Spiridon" University Hospital Iasi, Romania, were performed 137 PD. From these, 54 cases were histologic diagnosed with pancreatic cancer; 23 cases underwent pylorus preserving pancreatico-duodenectomy (PPPD) and 31 patients, classical Whipple procedure (PDW). Mean age was 59.07 +/- 1.42 years old (26-75 years old), and male to female ratio was 29 to 25. Jaundice was presented in 51 cases (94.4%), abdominal pain at 39 patients (72.2%) and Curvoisier-Terrier sign at 37 cases (68.7%). Fever was observe only in 4 cases (7.4%). Other biological and imaging parameters (e.g. main diameter of the biliary duct, tumor and wirsung ) were also discussed, but no significant difference was found between PPPD and PDW. Pancreatico-jejunostomy was performed in 41 cases (28 during the PDW and 13 in PPPD) and 13 pancreatico-gastrostomy (3 during PDW and 10 during PPPD). Mean operating time and mean blood loss in the PDW group were 358.22 +/- 10.53 minutes and 587.74 +/- 60.87 mL. After PPPD, these figures were 326.08 +/- 15.04 minutes and 571.74 +/- 90.50 mL, but no significant difference was noted. Delayed Gastric Emptying (DGE) was presented at 15 patients: 8 in PPPD group and 7 in PDW group (p=0.322). Postoperative morbidity rate (excluding DGE) was 33.33% (8 cases in PDW group and 10 in PPPD group). Pancreatic leak has a rate of 5.55% (3 cases--one in PPPD group vs two in PDW group), biliary leak has a rate of 12.96% (4 in PPPD group vs 3 in PDW group)and duodeno-jejunal anastomotic fistula appeared in one cases (PPPD). Acute postoperative pancreatitis is presented in one case (PPPD group) and postoperative hemorrhage appeared in 4 cases (2 in PPPD and 2 after PDW). Hospital stay was 19.91 +/- 2.28 days in PPPD group vs 18.87 +/- 2.24 days in PDW group (p = 0.751). Postoperative mortality rate was 5.5% (one case after PPD and 3 cases after PDW). Histological exam diagnosed ductal pancreatic adenocarcinoma in 51 cases (94.44%). Mean long-term survival rate was 20.98 months (10.52-31.45 months; 95 CI) and no difference was revealed between PPPD and PDW (log rank test - p = 0.796). CONCLUSION: PD should be performed for any pancreatic tumor even without preoperative histologic confirmation. The results after PPPD (postoperative morbidity and mortality, long-term survival) are similar to that following conventional Whipple procedure, if the principles of viable and tumor free margins are observed.

[Radiofrequency ablation in the multimodal treatment of liver metastases--preliminary report]. / Utilizarea termoablatiei prin radiofrecventa in tratamentul multimodal al metastazelor hepatice.

UNLABELLED: Although the "gold standard" in the multimodal treatment of liver primary and secondary tumors is the surgical ablation, the rate of resection, despite the last decades advances, remains still low (10 - 20%). In addition, the interest for non-surgical ablation therapies is increasing. Among them, regional or systemic chemotherapy, intra-arterial radiotherapy as well as locally targeted therapies--cryotherapy, alcohol instillation and radiofrequency (RF) are the most valuable options as alternative to the surgical approach. MATERIAL AND METHOD: Between February 2005 - January 2007, 9 patients with liver metastases underwent open RF ablation of their secondaries in the III-rd Surgical Unit, "St. Spiridon" Hospital. An Elektrotom 106 HiTT Berchtold device with a 60W power generator and a 15 mm monopolar active electrode was used. RESULTS: Destruction of the tumors was certified with intraoperative ultrasound examination. Pre- and postoperative CarcinoEmbryonic Antigen (CEA) together with imaging follow-up was carried out, in order to determine local or systemic recurrencies. Six patients died between 6 month - 4 years after the RF ablation. Median survival is 29.2 months. CONCLUSION: RF ablation is a challenge alternative in non-resectable liver tumors.

[Pancreaticoduodenectomy with or without pylorus preservation: a retrospective analysis of 137 patients]. / Duodenopancreatectomia cefalica cu sau fara prezervarea pilorului: analiza retrospectiva a 137 pacienti.

OBJECTIVE: We performed a retrospective study to assess the postoperative results, long-term survival and quality of life after pylorus preserving pancreaticoduodenectomy (PPPD) versus standard Whipple pancreaticoduodenectomy (WPD). METHODS: A retrospective study was performed in a nonselected series of 137 patients who were operated in the Surgical Clinics of "St. Spiridon" University Hospital Iasi, Romania, from January 1st, 1995 till December 31, 2005. Demographics, preoperative and intraoperative data, as well as postoperative morbidity, mortality and follow-up were analyzed. Quality of life, after to at least six months after discharge, was also studied. RESULTS: There were no significant differences noted in demographics data. Jaundice was more frequent in the PPPD group as for WPD patients (p=0.047). For the most patients the digestive reconstruction after resection were performed as in Child technique: the first anastomosis was pancreaticojejunostomy (end-to-end or end-to-side), the second anastomosis was hepaticojejunostomy (end-to-side) and the last anastomosis was gastrojejunostomy end-to-side (duodenojejunostomy in PPPD group). For 31 cases a pancreatico-gastrostomy were performed. We also noted 14 cases with pancreatico-gastrostomy and duodenojejunostomy end-to-end, and a Roux jejunal loop for 3 patients with previous gastrectomy and gastrojejunostomy (Reichel-Polya). The operating time was shorter in the PPPD group as in WPD (p < 10-3), but the mean blood loss was the same. Postoperative morbidity rate was 46.8% in PPPD group vs 39.2% in WPD (p > 0.05), but the reintervention rate was significant higher in PPPD group (30.6% vs 15%; p = 0.027). We also noted no significant differences of Delayed Gastric Emptying, postoperative mortality rate (14.5% in PPPD group vs 10.1% in WPD group) and mean survival time (42.42 months (24.94 - 59.89; 95% CI) in PPPD group vs 46.78 months (28.07 - 61.50; 95% CI) in WPD group; log rank test p = 0.643). Pathological exam diagnosed a malignancy in 109 cases (54 cases with pancreatic cancer); we noted chronic pancreatitis in 22 cases. Quality of life was also the same in the two groups. CONCLUSIONS: PPPD and WPD were associated with comparable results, but, there is a tendency of increase rate of postoperative morbidity and mortality for PPPD patients. We also noted that postoperative quality of life is the same for both procedures.

Invasive amebiasis.

Digestive amoebiasis with his invasive form is an unusual pathology encountered in the temperate zone. This could lead to a life threatening complication: systemic amoebiasis. A 55-year-old male was treated successfully of systemic amoebiasis in a third referral hospital. The diagnosis was established based on epidemiology data and microscopical identification of trophozoites of Entamoeba histolytica. The amoebicidal, antibiotic and supportive treatments was firstly administrated. The clinical picture of intestinal amoebiasis raised from dysenteric syndrome to necrotizing enteritis. The bowel perforation with localized peritonitis was followed by chronic enteric fistula. Amoebic liver abscess, as the most frequent extraintestinal complication, was concomitantly diagnosed and treated. Urinary amoebiasis was considered as complication in the context of systemic dissemination: any other location could become a site of an amoebic abscess. Multidisciplinary approach was the successful key in the management of the patient, including antiparasitic therapy and antibiotic prophylaxis, intensive care and multiple surgical approaches. The diagnosis of digestive amoebiasis and systemic complication may be delayed in nonendemic areas, leading to advanced and complicated stages of the disease. The surgical approach is most efficiently to treat a large liver amoebic abscess and intraperitoneal collections.

[Running through the liver transplantation]. / Parcursul transplantului hepatic.

An overview of the organization, timing and developing of the liver transplantation is difficult to be made in terms of multiple sequences and a great variety of activities during the developing of such activity. A well-trained transplant team must carry out the potential donor, the liver grafts manipulation and the graft receptor, in the condition of a competitive medical system. A summary presentation, showing the essentials of the proceedings in liver transplantation could be assimilated as a guide of multidisciplinary sequences that leads to the completion of the liver grafting. The common feature of all that means the liver transplantation and generally in organ transplantation is the performance and exactingness.

Laparoscopic assisted cholecystostomy.

Laparoscopic assisted cholecystostomy (LAC) is a safe method for external biliary drainage in jaundiced patients with distal common bile duct obstruction. It consists of the retrieval of the fundus of the gallbladder through the trocar, thus through abdominal wall followed by suture to the skin. This technique could be an option for surgeons who manage a patients with jaundice by distal common bile duct obstruction.

[Protein changes in the jejunal juice and endointestinal exudation of albumin-I 131 in acute infectious enterocolitis]. / Modificarile proteinelor din sucul jejunal si exsadatia endointestinala de albumina 131I în enterocolitele acute infectioase

The phenomenon of endointestinal protein exudation in acute infectious enterocolitis is studied. Total proteins were determined in 30 cases of acute enterocolitis and 50 of bacillary dysentery in the acute stages of the disease and convalescence. The proteinogram of the jejunal juice was performed in the acute stage and convalescence in 20 patients. In 16 patients and 5 controls endointestinal albumin elimination was determined quantitatively by means of 131I labeled albumin. The results showed increase in the total protein content in the jejunal juice in the course of acute infectious enterocolitis and bacillary dysentery and a return to normal values in convalescence. Electrophoresis of the jejunal juice in acute infectious enterocolitis showed the absence of fraction III with alpha1-globulin migration, and increased fractions I, II and IV probably due to the loss of endointestinal albumin, also confirmed by quantitative albumin determinations with 131I labeled albumin. In conclusion, patients with acute infectious enterocolitis present a marked loss of endointestinal albumins in the acute stage of the disease, with a return to normal values in convalescence.
