| 2 | Ischemic colitis:Clinical practice in diagnosis and treatment显示文摘Ischemic colitis is the most common form of ischemic injury of the gastrointestinal tract and can present either as an occlusive or a non-occlusive form. It accounts for 1 in 1000 hospitalizations but its incidence is underesti- mated because it often has a mild and transient nature. The etiology of ischemic colitis is multifactorial and the clinical presentation variable. The diagnosis is based on a combination of clinical suspicion, radiographic, endo- scopic and histological findings. Therapy and outcome depends on the severity of the disease. Most cases of the non-gangrenous form are transient and resolve spontaneously without complications. On the other hand, high morbidity and mortality and urgent operative intervention are the hallmarks of gangrenous ischemic colitis. | Angeliki Theodoropoulou Ioannis E Koutroubakis | 2008 | World Journal of Gastroenterology2008,14,48: | 75 |
| 3 | Endoscopic ultrasonography for gastric submucosal lesions显示文摘Gastric submucosal tumors(SMTs) are a rather frequent finding,occurring in about 0.36%of routine upper GIendoscopies.Endoscopic ultrasonography(EUS) has emerged as a reliable investigative procedure for evaluation of these lesions.Diagnostic EUS has the ability to differentiate intramural tumors from extraluminal compressions and can also show the layer of origin of gastric SMTs.Tumors can be further characterized by their layer of origin,echo pattern and margin.EUS-risk criteria of their malignant potential are presented,although the emergence of EUS-FNA has opened new indications for transmural tissue diagnosis and expanded the possibilities of EUS in SMTs of the stomach.Tissue diagnosis should address whether the SMT is a Gastrointestinal stromal tumour(GIST) or another tumor type and evaluate the malignant potential of a given GIST.However,there seems to be a lack of data on the optimal strategy in SMTs suspected to be GISTs with a negative EUS-FNA tissue diagnosis.The current management strategies,as well as open questions regarding their treatment are also presented. | Ioannis S Papanikolaou Konstantinos Triantafyllou Anastasia Kourikou Thomas Rsch | 2011 | World Journal of Gastrointestinal Endoscopy2011,3,5: | 44 |
| 4 | A case of successful management with splenectomy of intractable ascites due to congenital dyserythropoietic anemia type II-induced cirrhosis显示文摘The congenital dyserythropoietic anemias comprise agroup of rare hereditary disorders of erythropoiesis,characterized by ineffective erythropoiesis as thepredominant mechanism of anemia and by characteristicmorphological aberrations of the majority of erythroblastsin the bone marrow.Congenital dyserythropoieticanemia type II is the most frequent type.All types ofcongenital dyserythropoietic anemias distinctly share ahigh incidence of iron loading.Iron accumulation occurseven in untransfused patients and can result in heartfailure and liver cirrhosis.We have reported about apatient who presented with liver cirrhosis and intractableascites caused by congenital dyserythropoietic anemiatype Ⅱ.Her clinical course was further complicatedby the development of autoimmune hemolyticanemia.Splenectomy was eventually performed whichachieved complete resolution of ascites,increase ofhemoglobin concentration and abrogation of transfusionrequirements. | Themistoklis Vassiliadis Vassilia Garipidou Vassilios Perifanis Konstantinos Tziomalos OIga Giouleme Kalliopi Patsiaoura Michalis Avramidis Nikolaos Nikolaidis Sofia Vakalopoulou Ioannis Tsitouridis Antonios Antoniadis Panagiotis Semertzidis Anna Kioumi Evangelos Premetis Nikolaos Eugenidis | 2006 | World Journal of Gastroenterology2006,12,5: | 47 |
| 5 | Recurrence of choledocholithiasis following endoscopic bile duct clearance: Long term results and factors associated with recurrent bile duct stones显示文摘AIM To evaluate the rate of recurrence of symptomatic chol-edocholithiasis and identify factors associated with the recurrence of bile duct stones in patients who underwent endoscopic retrograde cholangiopancreatography(ERCP) and endoscopic sphincterotomy(EST) for bile duct stone disease.METHODS All patients who underwent ERCP and EST for bile duct stone disease and had their bile duct cleared from 1/1/2005 until 31/12/2008 was enrolled. All symptomatic recurrences during the study period(until 31/12/2015) were recorded. Clinical and laboratory data potentially associated with common bile duct(CBD) stone recurrence were retrospectively retrieved from patients' files.RESULTS A total of 495 patients were included. Sixty seven(67) out of 495 patients(13.5%) presented with recurrent symptomatic choledocholithiasis after 35.28 ± 16.9 mo while twenty two(22) of these patients(32.8%) experienced a second recurrence after 35.19 ± 23.2 mo. Factors associated with recurrence were size(diameter) of the largest CBD stone found at first presentation(10.2 ± 6.9 mm vs 7.2 ± 4.1 mm, P = 0.024), diameter of the CBD at the first examination(15.5 ± 6.3 mm vs 12.0 ± 4.6 mm, P = 0.005), use of mechanical lithotripsy(ML)(P = 0.04) and presence of difficult lithiasis(P = 0.04). Periampullary diverticula showed a trend towards significance(P = 0.066). On the contrary, number of stones, angulation of the CBD, number of ERCP sessions required to clear the CBD at first presentation, more than one ERCP session needed to clear the bile duct initially and a gallbladder in situ did not influence recurrence. CONCLUSION Bile duct stone recurrence is a possible late complication following endoscopic stone extraction and CBD clearance. It appears to be associated with anatomical parameters(CBD diameter) and stone characteristics(stone size, use of ML, difficult lithiasis) at first presentation. | Christos Konstantakis Christos Triantos Vasileios Theopistos Georgios Theocharis Ioannis Maroulis Georgia Diamantopoulou Konstantinos Thomopoulos | 2017 | World Journal of Gastrointestinal Endoscopy2017,9,1: | 46 |
| 6 | Efficacy of transcatheter embolization/chemoembolization (TAE/TACE) for the treatment of single hepatocellular carcinoma显示文摘AIM:To investigate the efficacy of transcatheter embolization/chemoembolization (TAE/TACE) in cirrhotic patients with single hepatocellular carcinoma (HCC) not suitable for surgical resection and percutaneous ablation therapy. METHODS:A cohort of 176 consecutive cirrhotic patients with single HCC undergoing TAE/TACE was reviewed; 162 patients had at least one image examination (helical CT scan or triphasic contrastenhanced MRI) after treatment and were included into the study. TAE was performed with Lipiodol followed by Gelfoam embolization; TACE was performed with Farmorubicin prepared in sterile drip at a dose of 50 mg/m2,infused over 30 min using a peristaltic pump,and followed by Lipiodol and Gelfoam embolization. RESULTS:Patients characteristics were:mean age,62 years; male/female 117/45; Child-Pugh score 6.2 ± 1.1; MELD 8.7 ± 2.3; mean HCC size,3.6 (range 1.0-12.0) cm. HCC size class was ≤ 2.0 cm,n = 51; 2.1-3.0 cm,n = 35; 3.1-4.0 cm,n = 29; 4.1-5.0 cm,n = 22; 5.1-6.0 cm,n = 11; and > 6.0 cm,n = 14. Patients received a total of 368 TAE/TACE (mean 2.4 ± 1.7). Complete tumor necrosis was obtained in 94 patients (58%),massive (90%-99%) necrosis in 16 patients (10%),partial (50%-89%) necrosis in 18 patients (11%) and poor (< 50%) necrosis in the remaining 34 patients (21%). The rate of complete necrosis according to the HCC size class was:69%,69%,52%,68%,50% and,13% for lesions of ≤ 2.0,2.1-3.0,3.1-4.0,4.1-5.0,5.1-6.0,and > 6.0 cm,respectively. Kaplan-Mayer survival at 24-mo was 88%,68%,59%,59%,45%,and 53% for lesions of ≤ 2.0,2.1-3.0,3.1-4.0,4.1-5.0,5.1-6.0,and > 6.0 cm,respectively. CONCLUSION:Our study showed that in cirrhotic patients with single HCC smaller than 6.0 cm,TAE/TACE produces complete local control of tumor in a significant proportion of patients. TAE/TACE is an effective therapeutic option in patients with single HCC not suitable for surgical resection or percutaneous ablation therapies. Further studies should investigate if the new available embolization agents or drug eluting beads may improve the effect on tumor necrosis. | Roberto Miraglia Giada Pietrosi Luigi Maruzzelli Ioannis Petridis Settimo Caruso Gianluca Marrone Giuseppe Mamone Giovanni Vizzini Angelo Luca Bruno Gridelli | 2007 | World Journal of Gastroenterology2007,13,21: | 38 |
| 7 | Intussusception of the bowel in adults:A review显示文摘Intussusception of the bowel is defined as the telescop-ing of a proximal segment of the gastrointestinal tract within the lumen of the adjacent segment.This condi-tion is frequent in children and presents with the classic triad of cramping abdominal pain,bloody diarrhea and a palpable tender mass.However,bowel intussusception in adults is considered a rare condition,accounting for 5% of all cases of intussusceptions and almost 1%-5%of bowel obstruction.Eight to twenty percent of cases are idiopathic,without a lead point lesion.Secondary intus-susception is caused by organic lesions,such as inflam-matory bowel disease,postoperative adhesions,Meckel's diverticulum,benign and malignant lesions,metastatic neoplasms or even iatrogenically,due to the presence of intestinal tubes,jejunostomy feeding tubes or after gas-tric surgery.Computed tomography is the most sensitive diagnostic modality and can distinguish between intus-susceptions with and without a lead point.Surgery is the definitive treatment of adult intussusceptions.Formal bowel resection with oncological principles is followed for every case where a malignancy is suspected.Reduction of the intussuscepted bowel is considered safe for benign lesions in order to limit the extent of resection or to avoid the short bowel syndrome in certain circumstances. | Athanasios Marinis Anneza Yiallourou Lazaros Samanides Nikolaos Dafnios Georgios Anastasopoulos Ioannis Vassiliou Theodosios Theodosopoulos | 2009 | World Journal of Gastroenterology2009,15,4: | 31 |
| 8 | Multipotent role of platelets in inflammatory bowel diseases:A clinical approach显示文摘There is evidence that inflammatory bowel diseases(IBD)combine both inflammation and coagulation in their pathogenesis and clinical manifestations.Although platelets(PLT)are well known for their role in hemo stasis,there are a rising number of studies supporting their considerable role as inflammatory amplifiers in chronic inflammatory conditions.IBD are associated with several alterations of PLT,including number shape,and function,and these abnormalities are main ly attributed to the highly activated state of circulating PLT in IBD patients.When PLT activate,they increase in size,release a great variety of bio-active inflamma tory and procoagulant molecules/particles,and express a variety of inflammatory receptors.These inflamma tory products may represent a part of the missing link between coagulation and inflammation,and can be considered as possible IBD pathogenesis instigators.In clinical practice,thrombocytosis is associated both with disease activity and iron deficiency anemia.Controlling inflammation and iron replacement in anemic patient usually leads to a normalization of PLT count.The aim of this review is to update the role of PLT in IBD and present recent data revealing the possible therapeutic implications of anti-PLT agents in future IBD remedies. | Evangelos Voudoukis Konstantinos Karmiris Ioannis E Koutroubakis | 2014 | World Journal of Gastroenterology2014,20,12: | 27 |
| 9 | Laparoscopic versus open appendectomy: Which way to go?显示文摘AIM: To compare the outcome of laparoscopic versus open appendectomy. METHODS: Prospectively collected data from 293 consecutive patients with acute appendicitis were studied. These comprised of 165 patients who underwent conventional appendectomy and 128 patients treated laparoscopically. The two groups were compared with respect to operative time, length of hospital stay, postoperative pain, complication rate and cost. RESULTS: There were no statistical differences regarding patient characteristics between the two groups. Conversion to laparotomy was necessary in 2 patients (1.5%). Laparoscopic appendectomy was associated with a shorter hospital stay (2.2 d vs 3.1 d, P = 0.04), and lower incidence of wound infection (5.3% vs 12.8%, P = 0.03). However, in patients with complicated disease, intra-abdominal abscess formation was more common after laparoscopic appendectomy (5.3% vs 2.1%, P = 0.002). The operative time and analgesia requirements were similar in the two groups. The cost of treatment was higher by 370 € in the laparoscopic group. CONCLUSION: Laparoscopic appendectomy is as safe and effi cient as open appendectomy, provided surgical experience and equipment are available. | Ioannis Kehagias Stavros Nikolaos Karamanakos Spyros Panagiotopoulos Konstantinos Panagopoulos Fotis Kalfarentzos | 2008 | World Journal of Gastroenterology2008,14,31: | 25 |

| 11 | Review article: Update on current and emergent data on hepatopulmonary syndrome显示文摘Hepatopulmonary syndrome(HPS) is a frequent pulmonary complication of end-stage liver disease, characterized by impaired arterial oxygenation induced by intrapulmonary vascular dilatation. Its prevalence ranges from 4% to 47% in patients with cirrhosis due to the different diagnostic criteria applied among different studies. Nitric oxide overproduction and angiogenesis seem to be the hallmarks of a complicated pathogenetic mechanism, leading to intrapulmonary shunting and ventilation-perfusion mismatch. A classification of HPS according to the severity of hypoxemia has been suggested. Contrast-enhanced echocardiography represents the gold standard method for the detection of intrapulmonary vascular dilatations which is required, in combination with an elevated alveolar arterial gradient to set the diagnosis. The only effective treatment which can modify the syndrome's natural history is liver transplantation. Although it is usually asymptomatic, HPS imparts a high risk of pretransplantation mortality, independently of the severity of liver disease, while there is variable data concerning survival rates after liver transplantation. The potential of myocardial involvement in the setting of HPS has also gained increasing interest in recent research. The aim of this review is to critically approach the existing literature of HPS and emphasizeunclear points that remain to be unraveled by future research. | Stergios Soulaidopoulos Evangelos Cholongitas George Giannakoulas Maria Vlachou Ioannis Goulis | 2018 | World Journal of Gastroenterology2018,24,12: | 26 |
| 12 | Current surgical strategies for total arthroplasty in valgus knee显示文摘The majority of orthopaedic surgeons even currentlyagree that primary total arthroplasty in valgus knees with a deformity of more than ten degrees may prove challenging. The unique sets of bone and soft tissue abnormalities that must be addressed at the time of the operation make accurate axis restoration, component orientation and joint stability attainment a difficult task. Understanding the specific pathologic anatomic changes associated with the valgus knee is a prerequisite so as to select the proper surgical method, to optimize component position and restore soft-tissue balance. The purpose of this article is to review the valgus knee anatomical variations, to assess the best pre-operative planning and to evaluate how to choose the grade of constraint of the implant. It will also be underlying the up-to-date main approaches and surgical techniques be proposed in the English literature both for bone cuts and soft tissue management of valgus knees. | Dimitrios Nikolopoulos Ioannis Michos George Safos Petros Safos | 2015 | World Journal of Orthopedics2015,6,6: | 20 |
| 13 | Management of patients after recovering from acute severe biliary pancreatitis显示文摘Cholelithiasis is the most common cause of acute pancreatitis,accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned,the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management,including cholecystectomy,endoscopic retrograde cholangiopancreatography(ERCP) and sphincterotomy,or no definitive treatment. Delaying cholecystectomy until after resolution of the inflammatory process,usually not earlier than 6 wk after onset of acute pancreatitis,seems to be a safe policy. ERCP and sphincterotomy on index admission prevent recurrent episodes of pancreatitis until cholecystectomy is performed,but if used for definitive treatment,they can be a valuable tool for patients unfit for surgery. Some patients who survive severe biliary pancreatitis may develop pseudocysts or walled-off necrosis. Management of pseudocysts with minimally invasive techniques,if not therapeutic,can be used as a bridge to definitive operative treatment,which includes delayed cholecystectomy and concurrent pseudocyst drainage in some patients. A management algorithm has been developed for patients surviving severe biliary pancreatitis according to the currently published data in the literature. | Georgia Dedemadi Manolis Nikolopoulos Ioannis Kalaitzopoulos George Sgourakis | 2016 | World Journal of Gastroenterology2016,22,34: | 20 |

| 15 | Clinical impact of microbiome in patients with decompensated cirrhosis显示文摘Cirrhosis is an increasing cause of morbidity and mortality. Recent studies are trying to clarify the role of microbiome in clinical exacerbation of patients with decompensated cirrhosis. Nowadays, it is accepted that patients with cirrhosis have altered salivary and enteric microbiome, characterized by the presence of dysbiosis. This altered microbiome along with small bowel bacterial overgrowth, through translocation across the gut, is associated with the development of decompensating complications. Studies have analyzed the correlation of certain bacterial families with the development of hepatic encephalopathy in cirrhotics. In general, stool and saliva dysbiosis with reduction of autochthonous bacteria in patients with cirrhosis incites changes in bacterial defenses and higher risk for bacterial infections, such as spontaneous bacterial peritonitis, and sepsis. Gut microbiome has even been associated with oncogenic pathways and under circumstances might promote the development of hepatocarcinogenesis. Lately, the existence of the oral-gutliver axis has been related with the development of decompensating events. This link between the liver and the oral cavity could be via the gut through impaired intestinal permeability that allows direct translocation of bacteria from the oral cavity to the systemic circulation. Overall, the contribution of the microbiome to pathogenesis becomes more pronounced with progressive disease and therefore may represent an important therapeutic target in the management of cirrhosis. | Theodora Oikonomou George V Papatheodoridis Michael Samarkos Ioannis Goulis Evangelos Cholongitas | 2018 | World Journal of Gastroenterology2018,24,34: | 16 |
| 16 | Endoscopic ultrasound-guided fine-needle aspiration cytology diagnosis of solid pseudopapillary tumor of the pancreas: A case report and literature review显示文摘We describe the clinical, imaging and cytopathological features of solid pseudopapillary tumor of the pancreas (SPTP) diagnosed by endoscopic ultrasound- guided (EUS-guided) fine-needle aspiration (FNA). A 17-year-old woman was admitted to our hospital with complaints of an unexplained episodic abdominal pain for 2 mo and a short history of hypertension in the endocrinology clinic. Clinical laboratory examinations revealed polycystic ovary syndrome, splenomegaly and low serum amylase and carcinoembryonic antigen (CEA) levels. Computed tomography (CT) analysis revealed a mass of the pancreatic tail with solid and cystic consistency. EUS confirmed the mass, both in body and tail of the pancreas, with distinct borders, which caused dilation of the peripheral part of the pancreatic duct (major diameter 3.7 mm). The patient underwent EUS-FNA. EUS-FNA cytology specimens consisted of single cells and aggregates of uniform malignant cells, forming microadenoid structures, branching, papillary clusters with delicate fibrovascular cores and nuclear overlapping. Naked capillaries were also seen. The nuclei of malignant cells were round or oval, eccentric with fine granular chromatin, small nucleoli and nuclear grooves in some of them. The malignant cells were periodic acid Schiff (PAS)-Alcian blue (+) and immunocytochemically they were vimentin (+), CA 19.9 (+), synaptophysin (+), chromogranin (-), neuro-specific enolase (-), a1- antitrypsin and a1-antichymotrypsin focal positive. Cytologic findings were strongly suggestive of SPTP. Biopsy confirmed the above cytologic diagnosis. EUS- guided FNA diagnosis of SPTP is accurate. EUS findings,cytomorphologic features and immunostains of cell block help distinguish SPTP from pancreatic endocrine tumors, acinar cell carcinoma and papillary mucinous carcinoma. | Charitini Salla Paschalis Chatzipantelis Panagiotis Konstantinou Ioannis Karoumpalis Akrivi Pantazopoulou Victoria Dappola | 2007 | World Journal of Gastroenterology2007,13,38: | 15 |
| 17 | Risk factors for gastroesophageal reflux disease and analysis of genetic contributors显示文摘Gastroesophageal reflux disease(GERD) is a common gastrointestinal disorder with an increasing prevalence. GERD develops when the reflux of stomach contents causes troublesome typical and atypical symptoms and/or complications. Several risk factors of GERD have been identified and evaluated over the years, including a considerable amount of genetic factors. Multiple mechanisms are involved in the pathogenesis of GERD including:(1) motor abnormalities, such as impaired lower esophageal sphincter(LES) resting tone, transient LES relaxations, impaired esophageal acid clearance and delayed gastric emptying; and(2) anatomical factors, such as hiatal hernia and obesity. Genetic contribution seems to play a major role in GERD and GERD-related disorders development such Barrett's esophagus and esophageal adenocarcinoma. Twin and family studies have revealed an about 31% heritability of the disease. Numerous single-nucleotide polymorphisms in various genes like FOXF1, MHC, CCND1, anti-inflammatory cytokine and DNA repair genes have been strongly associated with increased GERD risk. GERD, Barrett'sesophagus and esophageal adenocarcinoma share several genetic loci. Despite GERD polygenic basis,specific genetic loci such as rs10419226 on chromosome 19, rs2687201 on chromosome 3, rs10852151 on chromosome 15 and rs520525 on the paired related homeobox 1 gene have been mentioned as potential risk factors. Further investigation on the risk genes may elucidate their exact function and role and demonstrate new therapeutic approaches to this increasingly common disease. | Alexandra Argyrou Evangelia Legaki Christos Koutserimpas Maria Gazouli Ioannis Papaconstantinou George Gkiokas George Karamanolis | 2018 | World Journal of Clinical Cases2018,6,8: | 14 |
| 18 | Comparative clinical study of ultrasound-guided A1 pulley release vs open surgical intervention in the treatment of trigger finger显示文摘AIM To investigate the effectiveness of ultrasound-guided release of the first annular pulley and compare results with the conventional open operative technique.METHODS In this prospective randomized, single-center, clinical study, 32 patients with trigger finger or trigger thumb, grade Ⅱ-Ⅳ according to Green classification system, were recruited. Two groups were formed; Group A(16 patients) was treated with an ultrasound-guided percutaneous release of the affected A1 pulley under local anesthesia. Group B(16 patients) underwent an open surgical release of the A1 pul ey, through a 10-15 mm incision. Patients were assessed pre- and postoperatively(follow-up:2,4 and 12 wk) by physicians blinded to the procedures. Treatment of triggering(primary variable of interest) was expressed as the 'success rate' per digit. The time for taking postoperative pain killers, range of motion recovery, QuickD ASH test scores(Greek version), return to normal activities(including work), complications and cosmetic results were assessed.RESULTS The success rate in group A was 93.75%(15/16) and in group B 100%(16/16). Mean times in group A patients were 3.5 d for taking pain killers, 4.1 d for returning to normal activities, and 7.2 and 3.9 d for complete extension and flexion recovery, respectively. Mean Quick DASH scores in group A were 45.5 preoperatively and, 7.5, 0.5 and 0 after 2, 4, and 12 wk postoperatively. Mean times in group B patients were 2.9 d for taking pain killers, 17.8 d for returning to normal activities, and 5.6 and 3 d for complete extension and flexion recovery. Mean QuickD ASH scores in group B were 43.2 preoperatively and, 8.2, 1.3 and 0 after 2, 4, and 12 wk postoperatively. The cosmetic results found excellent or good in 87.5%(14/16) of group A patients, while in 56.25%(9/16) of group B patients were evaluated as fair or poor.CONCLUSION Treatment of the trigger finger using ultrasonography resulted in fewer absence of work days, and better cosmetic results, in comparison with the open surgery technique. It is a promising method that represents excellent results without major complications, so that it could be possibly be established as a first-line treatment in the trigger finger's disease. | Vasileios S Nikolaou Michael-Alexander Malahias Maria-Kyriaki Kaseta Ioannis Sourlas George C Babis | 2017 | World Journal of Orthopedics2017,8,2: | 14 |
| 19 | Clinical considerations and therapeutic strategy for sigmoid volvulus in the elderly:A study of 33 cases显示文摘AIM: To evaluate different types of treatment for sigmoid volvulus and clarify the role of endoscopic intervention versus surgery. METHODS: A retrospective review of the clinical presentation and imaging characteristics of 33 sigmoid volvulus patients was presented, as well as their diagnosis and treatment, in combination with a literature review. RESULTS: In 26 patients endoscopic detorsion was achieved after the first attempt and one patient died because of uncontrollable sepsis despite prompt operative treatment. Seven patients had unsuccessful endoscopic derotation and were operated on. On two patients with gangrenous sigmoid, Hartmann's procedure was performed. In five patients with viable colon, a sigmoid resection and primary anastomosis was carried out. Three patients had a lavage 'on table' prior to anastomosis, while in the remaining 2 patients a diverting stoma was performed according to the procedure of the first author. Ten patients were operated on during their first hospital stay (3 to 8 d after the deflation). All patients had viable colon; 7 patients had a sigmoid resection and primary anastomosis, 2 patients had sigmoidopexy and one patient underwent a near-total colectomy. Two patients (sigmoidectomy-sigmoidopexy) had recurrences of volvulus 43 and 28 mo after the initial surgery. Among 15 patients who were discharged from the hospital after non-operative deflation, 3 patients were lost to follow-up. Of theremaining 12 patients, 5 had a recurrence of volvulus at a time in between 23 d and 14 mo. All the five patients had been operated on and in four a gangrenous sigmoid was found. Three patients died during the 30 d postoperative course. The remaining seven patients were admitted to our department for elective surgery. In these patients, 2 subtotal colectomies, 3 sigmoid resections and 2 sigmoidopexies were carried out. One patient with subtotal colectomy died. Taken together of the results, it is evident that after 17 elective operations we had only one death (5.9%), whereas after 15 emergency operations 6 patients died, which means a mortality rate of 40%. CONCLUSION: Although sigmoid volvulus causing intestinal obstruction is frequently successfully encountered by endoscopic decompression, however, the principal therapy of this condition is surgery. Only occasionally in patients with advanced age, lack of bowel symptoms and multiple co-morbidities might surgical repair not be considered. | Michael Safioleas Constantinos Chatziconstantinou Evangelos Felekouras Michael Stamatakos Ioannis Papaconstantinou Anastasios Smirnis Panagiotis Safioleas Alkiviades Kostakis | 2007 | World Journal of Gastroenterology2007,13,6: | 10 |
| 20 | Current status of laparoendoscopic rendezvous in the treatment of cholelithiasis with concomitant choledocholithiasis显示文摘The current evidence in favor of the laparoendoscopic rendezvous is promising and demonstrates the main advantages of this technique in regard to shorter hospital stay and selective cannulation of the commonbile duct(CBD), avoiding thus the inadvertent cannulation of the pancreatic duct. In addition, in the rendezvous technique the contrast medium is not injected retrogradely as during the traditional endoscopic retrograde cholangiopancreatography(ERCP), when the medium accidentally could be injected under pressure into the pancreatic duct. The RV technique minimizes that risk. Both these main advantages of the RV technique over the classic ERCP, are related with a significant lower incidence of hyperamylasemia and post-ERCP pancreatitis, compared with the traditional two stage procedure. Choledocholithiasis is present in 10% to 15% of patients undergoing cholecystectomy. To date, the ideal management of CBD stones remains controversial. Prospective randomized trials have shown that laparoscopic management of the CBD stones, as a single stage procedure, is the most efficient and cost effective method of treatment. Laparoendoscopic rendezvous has been proposed as an alternative single stage approach. Several studies have shown the effective use of this technique in the treatment of CBD stones by improving patient compliance and clinical results including shorter hospital stay, higher success rate and less cost. The current evidence about the use of this technique presented in this review article is promising and demonstrates the main advantages of the procedure. | Ioannis Baloyiannis George Tzovaras | 2015 | World Journal of Gastrointestinal Endoscopy2015,7,7: | 10 |
