RESUMEN

BACKGROUND: The aim of this study was to compare postoperative outcomes following liver resection between patients with prolonged cumulative ischemia time (CIT) which exceeded 60 min and patients with CIT less than 60 min. METHODS: Between March 2020 and October 2022, 164 consecutive patients underwent liver resection at the Unit for hepato-bilio-pancreatic surgery, University Clinic for Digestive Surgery in Belgrade, Serbia. Intermittent Pringle maneuver was routinely applied. Depending on CIT during transection, patients were divided into two groups: group 1 (CIT <60 min) included 101 patients, and group 2 (CIT ≥60 min) included 63 patients. RESULTS: Median operative time (210 vs. 400 min) and CIT (30 vs. 76 min) were longer in the Group 2 (p < 0.001). Intraoperative blood loss was higher in the Group 2 (150 vs 500 ml), p < 0.001. The perioperative transfusion rate was similar between the groups (p = 0.107). There was no difference in postoperative overall morbidity (50.5% vs. 58.7%, p = 0.337) and major morbidity (18.8 vs. 19%, p = 0.401). In-hospital mortality, 30-day mortality, and 90-day mortality were similar between the groups (p = 0.408; p = 0.408; p = 0.252, respectively). Non-anatomical liver resection was the only predictive factor of 90-day mortality identified by multivariate analysis (p = 0.047; Relative Risk = 0.179; 95% Confidence Interval 0.033-0.981). CONCLUSION: Intermittent Pringle maneuver with CIT exceeding 60 min is a safe method for bleeding control during liver resection with no impact on postoperative morbidity and mortality.

RESUMEN

BACKGROUND: Transarterial chemoembolisation (TACE) is the primary treatment for intermediate-stage hepatocellular carcinoma (HCC), according to the updated Barcelona Clinic Liver Cancer (BCLC) staging system. Although growing evidence favours liver resection (LR) over TACE for intermediate-stage HCC, the best treatment option remains controversial. This meta-analysis aimed to compare the overall survival (OS) after LR versus TACE for intermediate-stage HCC. METHODS: A comprehensive literature review of PubMed, Embase, Cochrane Library, and Web of Science was performed. Studies that compared the efficacy of LR and TACE in patients with intermediate (BCLC stage B) HCC were selected. According to the recent updated BCLC classification, intermediate stage of HCC was defined as follows: (a) four or more HCC nodules of any size, or (b) two or three nodules, but if at least one tumour is larger than 3 cm. The main outcome was OS, expressed as the hazard ratio. RESULTS: Nine eligible studies of 3355 patients were included in the review. The OS of patients who underwent LR was significantly longer than that of patients who underwent TACE (hazard ratio=0.52; 95% CI: 0.39-0.69; I2=79%). Prolonged survival following LR was confirmed after sensitivity analysis of five studies using propensity score matching (HR=0.45; 95% CI: 0.34-0.59; I2=55%). CONCLUSION: Patients with intermediate-stage HCC who underwent LR had a longer OS that those who underwent TACE. The role of LR in patients with BCLC stage B should be clarified in future randomised controlled trials.

RESUMEN

Solid pseudopapillary neoplasm (SPN) is rare pancreatic tumor occurring most commonly in young females. The typical imaging appearance of SPN is of well-defined, encapsulated, and large heterogeneous tumors, consisting of solid and cystic components due to various degrees of intralesional hemorrhage and necrosis. However, atypical imaging presentation in the form of small solid tumors or uniformly cystic lesions might also be seen, which can be explained by specific pathological characteristics. Other imaging features such as a round shape, the absence of main pancreatic duct dilatation, and slow growth, in combination with vague symptoms, favor the diagnosis of SPNs. Nevertheless, the radiological findings of SPN might overlap with other solid and cystic pancreatic neoplasms, such as neuroendocrine tumors, serous and mucinous neoplasms, and even small pancreatic adenocarcinomas. In addition, a few benign non-tumorous conditions including walled-of-necrosis, and intrapancreatic accessory spleen may also pose diagnostic dilemmas simulating SPNs on imaging studies. The aim of this manuscript is to provide a comprehensive overview of the typical and atypical imaging features of SPNs and to describe useful tips for differential diagnosis with its potential mimickers.

RESUMEN

A coexistance of liver cystic echinococcosis (CE) and hepatocellular carcinoma (HCC) is very rare. HCC is the leading cause of cancer-related mortality worldwide, while CE is a globally endemic zoonosis caused by the cestode tapeworm Echinococcus granulosus. The association between these two diseases is still not well-defined. A preoperative diagnosis may be challenging, especially if HCC and CE present as a single lesion and if atypical imaging features are present. Herein, we present a case of the patient that was initially diagnosed as an extensive necrotic tumor in the left liver lobe and highly suspicious of being HCC associated with peritumoral hematoma. Left hemihepatectomy was performed, and the histopathological findings showed the collision of two lesions: a hydatid cyst and HCC.

RESUMEN

Intrahepatic cholangiocarcinoma (ICC) is the second most common primary hepatic malignancy, with mass-forming growth pattern being the most common. The typical imaging appearance of mass-forming ICC (mICC) consists of irregular ring enhancement in the arterial phase followed by the progressive central enhancement on portal venous and delayed phases. However, atypical imaging presentation in the form of hypervascular mICC might also be seen, which can be attributed to distinct pathological characteristics. Ancillary imaging features such as lobular shape, capsular retraction, segmental biliary dilatation, and vascular encasement favor the diagnosis of mICC. Nevertheless, these radiological findings may also be present in certain benign conditions such as focal confluent fibrosis, sclerosing hemangioma, organizing hepatic abscess, or the pseudosolid form of hydatid disease. In addition, a few malignant lesions including primary liver lymphoma, hemangioendothelioma, solitary hypovascular liver metastases, and atypical forms of hepatocellular carcinoma (HCC), such as scirrhous HCC, infiltrative HCC, and poorly differentiated HCC, may also pose a diagnostic dilemma by simulating mICC in imaging studies. Diffusion-weighted imaging and the use of hepatobiliary contrast agents might be helpful for differential diagnosis in certain cases. The aim of this manuscript is to provide a comprehensive overview of mICC imaging features and to describe useful tips for differential diagnosis with its potential mimickers.

RESUMEN

BACKGROUND: The utility of intravoxel incoherent motion (IVIM) related parameters in differentiation of hypovascular liver lesions is still unknown. PURPOSE: The purpose of this study was to evaluate the value of IVIM related parameters in comparison to apparent diffusion coefficient (ADC) for differentiation among intrahepatic mass-forming cholangiocarcinoma (IMC), and hypovascular liver metastases (HLM). METHODS: Seventy-four prospectively enrolled patients (21 IMC, and 53 HLM) underwent 1.5T magnetic resonance examination with IVIM diffusion-weighted imaging using seven b values (0-800 s/mm2). Two independent readers performed quantitative analysis of IVIM-related parameters and ADC. Interobserver reliability was tested using a intraclass correlation coefficient. ADC, true diffusion coefficient (D), perfusion-related diffusion coefficient (D*), and perfusion fraction (ƒ) were compared among the lesions using Kruskal-Wallis H test. The diagnostic accuracy of each parameter was assessed by receiver operating characteristic (ROC) curve analysis. RESULTS: The interobserver agreement was good for ADC (0.802), and excellent for D, D*, and ƒ (0.911, 0.927, and 0.942, respectively). ADC, and D values were significantly different among IMC and HLM (both p < 0.05), while there was no significant difference among these lesions for ƒ and D* (p = 0.101, and p = 0.612, respectively). ROC analysis showed higher diagnostic performance of D in comparison to ADC (AUC = 0.879 vs 0.821). CONCLUSION: IVIM-derived parameters in particular D, in addition to ADC, could help in differentiation between most common hypovascular malignant liver lesions, intrahepatic mass-forming cholangiocarcinoma and hypovascular liver metastases.

RESUMEN

BACKGROUND: Low grade fibromyxoid sarcoma (LGFMS) is a rare and benign mesenchymal tumor with indolent course, most commonly found in young or middle-aged men. The majority of the LGFMSs are located in the trunk and deep soft tissue of the lower extremities. They appear as well circumscribed, although not encapsulated, which often leads to incomplete surgical resection. Despite their seemingly benign appearance, these tumors have aggressive behavior with high metastatic and recurrence rates. Accurate histopathologic examination of the specimen and its immunohistochemical analysis are mandatory for a precise diagnosis. CASE SUMMARY: We report a case of a 38 year-old-man who presented with jaundice and upper abdominal discomfort. Multi-detector computed tomography and magnetic resonance imaging showed a large left liver tumor mass, extending to the hepatoduodenal ligament. Left hepatectomy was performed with resection and reconstruction of hepatic artery and preservation of middle hepatic vein. Histopathologic examination confirmed the tumor being a low-grade fibromyxoid sarcoma. Three and a half years after surgery, the patient died after being diagnosed with spine metastasis. CONCLUSION: Due to poor response to all modalities of adjuvant treatment, we consider that the focus of treatment should be on surgery as the only option for curing the disease.

RESUMEN

Pancreatic pseudoaneurysm is a rare but life-threatening clinical entity. In this paper, we present a case of a 74-year-old man, who was admitted to our clinic with a diagnosis of an acute on chronic pancreatitis complicated by walled-off-pancreatic-necrosis, with subsequent development of peripancreatic pseudoaneurysm. After initial conservative management, the patient recovered and was discharged from the hospital. However, he soon returned feeling anxious due to a pulsatile abdominal mass. Abdominal Color-Doppler examination, CT scan, and angiography revealed large pancreatic necrotic collection in the total size of 9 cm, with centrally enhancing area of 3.5 cm that corresponded to pseudoaneurysm originating from the posterior pancreaticoduodenal vascular arcade. Considering the size, location of the pseudoaneurysm, feeding vessel, and poor general patients condition, we opted for minimally invasive treatment. Pseudoaneurysm was successfully managed by endovascular coil embolization, i.e., "sandwich technique".

RESUMEN

Hepatocellular carcinoma (HCC) is the most common primary hepatic malignancy, which usually arises in cirrhotic liver. When the typical enhancement pattern, consisting of late arterial hyperenhancement followed by washout, is present in nodules larger than 1 cm, HCC can be confidently diagnosed without the need for tissue biopsy. Nevertheless, HCC can display an atypical enhancement pattern, either as iso or hypovascular lesion, or hypervascular lesion without washout. Not only the enhancement pattern of HCC could be atypical, but also a variety of histological types of HCC, such as steatotic, scirrhous, fibrolamellar, or combined hepatocellular-cholangiocellular carcinoma could raise diagnostic dilemmas. In addition, distinct morphological types of HCC or different growth pattern can occur. Awareness of these atypical and rare HCC presentations on magnetic resonance imaging is important for accurate differentiation from other focal liver lesions and timely diagnosis, which allows optimal treatment of patients.

RESUMEN

BACKGROUND: Rectal cancer (RC) is one of the most common diagnosed cancers, and one of the major causes of cancer-related death nowadays. Majority of the current guidelines rely on TNM classification regarding therapy regiments, however recent studies suggest that additional histopathological findings could affect the disease course. AIM: To determine whether perineural invasion alone or in combination with lymphovascular invasion have an effect on 5-years overall survival (OS) of RC patients. METHODS: A prospective study included newly diagnosed stage I-III RC patients treated and followed at the Digestive Surgery Clinic, Clinical Center of Serbia, between the years of 2014-2016. All patients had their diagnosis histologically confirmed in accordance with both TMN and Dukes classification. In addition, the patient's demographics, surgical details, postoperative pathological details, differentiation degree and their correlation with OS was investigated. RESULTS: Of 245 included patients with stage I-III RC, lymphovascular invasion (LVI) was identified in 92 patients (38%), whereas perineural invasion (PNI) was present in 46 patients (19%). Using Kaplan-Meier analysis for overall survival rate, we have found that both LVI and PNI were associated with lower survival rates (P < 0.01). Moreover when Cox multiple regression model was used, LVI, PNI, older age, male gender were predictors of poor prognosis (HR = 5.49; 95%CI: 2.889-10.429; P < 0.05). CONCLUSION: LVI and PNI were significant factors predicting worse prognosis in early and intermediate RC patients, hence more aggressive therapy should be reserved for these patients after curative resection.

RESUMEN

Gastroesophageal Reflux Disease (GERD) is characterized by acid and bile reflux in the distal oesophagus, and this may cause the development of reflux esophagitis and Barrett's oesophagus (BE). The natural histological course of untreated BE is non-dysplastic or benign BE (ND), then lowgrade (LGD) and High-Grade Dysplastic (HGD) BE, with the expected increase in malignancy transfer to oesophagal adenocarcinoma (EAC). The gold standard for BE diagnostics involves high-resolution white-light endoscopy, followed by uniform endoscopy findings description (Prague classification) with biopsy performance according to Seattle protocol. The medical treatment of GERD and BE includes the use of proton pump inhibitors (PPIs) regarding symptoms control. It is noteworthy that long-term use of PPIs increases gastrin level, which can contribute to transfer from BE to EAC, as a result of its effects on the proliferation of BE epithelium. Endoscopy treatment includes a wide range of resection and ablative techniques, such as radio-frequency ablation (RFA), often concomitantly used in everyday endoscopy practice (multimodal therapy). RFA promotes mucosal necrosis of treated oesophagal region via high-frequency energy. Laparoscopic surgery, partial or total fundoplication, is reserved for PPIs and endoscopy indolent patients or in those with progressive disease. This review aims to explain distinct effects of PPIs and RFA modalities, illuminate certain aspects of molecular mechanisms involved, as well as the effects of their concomitant use regarding the treatment of BE and prevention of its transfer to EAC.

RESUMEN

PURPOSE: The primary aim of this study was to evaluate the benefit of extended lymphadenectomy in pancreaticoduodenectomy (PD) and to estimate its impact on long-term survival in patients with pancreatic head carcinoma. Secondary endpoints included perioperative mortality, postoperative morbidity and predictors of survival in patients undergoing standard versus extended lymphadenectomy for pancreatic head carcinoma. METHODS: From January 2007 to December 2010, 60 patients with potentially resectable pancreatic head carcinoma were operated using pylorus-preserving pancreatoduodenectomy (PPPD) at the Clinic for Digestive Surgery, Clinical Center of Serbia, Belgrade. Intraoperatively patients were randomly stratified into two groups: the first group (N1=30) underwent PPPD with standard lymphadenectomy whilst the second group (N2=30) was operated with PPPD with extended lymphadenectomy. None of the patients received adjuvant treatments. RESULTS: The number of retrieved lymph nodes, mean operating time and postoperative hospital stay were greater in patients with extended lymphadenectomy . Cox regression analysis showed that stage and lymph node metastasis were independent prognostic factors for survival. CONCLUSION: Extended lymphadenectomy in PPPD did not improve long-term survival in patients with resectable pancreatic head carcinoma and led to comparable and similar morbidity and mortality rates to those after standard lymphadenectomy.

RESUMEN

INTRODUCTION: Autoimmune cholangitis or immunoglobulin G4-associated cholangitis (IAC) has been recently regarded as a new clinical and histopathological entity and is a part of a complex autoimmune disorder--IgG4-related systemic disease (ISD). ISD is an autoimmune disease with multi-organic involvement, characterized with IgG4-positive plasmocytic infiltration of various tissues and organs with a consequent sclerosis, which responds well to steroid therapy. Most commonly affected organs are the pancreas (autoimmune pancreatitis, [AIP]) and the common bile duct (IAC). IAC and cholangiocarcinoma (CCA) share many clinical, laboratory and imaging findings. CASE OUTLINE: We present a case of a 60-year-old male with a biliary stricture of a common bile duct, which was clinically considered as a bile duct carcinoma and treated surgically. Definite histopathological findings and immunohistochemistry revealed profound chronic inflammation, showing lymphoplasmacytic IgG-positive infiltration of a resected part of a common bile duct, highly suggestive for the diagnosis of IAC. In addition, postoperative IgG4 serum levels were also increased. CONCLUSION: It is of primary clinical importance to make a difference between IAC and CCA, in order to avoid unnecessary surgical intervention. Therefore, IAC should be considered in differential diagnosis in similar cases.

RESUMEN

Primary retroperitoneal mucinous cystic tumors are extremely rare. These tumors can be classified as a primary retroperitoneal mucinous cystadenoma with or without borderline malignancy or primary retroperitoneal mucinous cystadenocarcinoma. The most common of these is primary retroperitoneal mucinous cystadenoma, which almost always occurs in female patients; only ten cases have been reported in males. The most common clinical findings for this tumor type include nonspecific abdominal pain and a palpable abdominal mass. A definitive diagnosis is usually obtained from histopathology after surgical excision. Here, we report the case of a 60-year-old female patient who complained of abdominal pain that had been present for 3 mo and presented with a palpable abdominal mass. Multidetector computed tomography scanning revealed a large, unilocular cystic mass in the left retroperitoneal space. Surgical intervention was performed and the tumor was completely removed. Histopathologic examination confirmed that the tumor was a primary retroperitoneal mucinous cystadenoma. Two years after surgery, the patient remains disease free.

RESUMEN

INTRODUCTION: Accessory spleens can be found in up to 10% of the population, and their intrapancreatic occurrence is considered uncommon. When present, the intrapancreatic accessory spleen is usually found in the tail of the pancreas in about 1.7% of adult individuals. The infrequent presence of the accessory spleen in the pancreatic tissue could lead to inappropriate diagnosis and hence therapeutic approach, as they are commonly presented as a hypervascular node in the tail of the pancreas on abdominal CT and MRI, mimicking a well differentiated tumor of the pancreas or non-functioning pancreatic neuroendocrine tumor. CASE OUTLINE: We present a 70-year-old female in whom a preoperative evaluation finding was highly suggestive of a non-functioning neuroendocrine tumor of the pancreatic tail. We performed spleen preserving laparoscopic distal pancreatectomy, and histopathological examination revealed the intrapancreatic accessory spleen. CONCLUSION: Although infrequent, the presence of the intrapancreatic accessory spleen must be considered in the differential diagnosis of pancreatic tail tumors.

RESUMEN

AIM: To determine predictors of clinically relevant pancreatic fistulas (CRPF) by measuring drain fluid amylase (DFA) in the early postoperative period. METHODS: This prospective clinical study included 382 patients with periampullary tumors that were surgically resected at our department between March 2005 and October 2012. A cephalic duodenopancreatectomy (DP) was performed on all patients. Two closed suction drains were placed at the end of the surgery. The highest postoperative DFA value was recorded and analyzed during the first three postoperative days and on subsequent days if the drains were kept longer. Pancreatic fistula (PF) was classified according to the International Study Group of Pancreatic Fistula (ISGPF) criteria. Postoperative complications were defined according to the Dindo-Clavien classification. All data were statistically analyzed. The optimal thresholds of DFA levels on the first, second and third postoperative days were estimated by constructing receiver operating curves, generated by calculating the sensitivities and specificities of the DFA levels. The DFA level limits were used to differentiate between the group without PF and the groups with biochemical pancreatic fistula (BPF) and CRPF. RESULTS: Pylorus-preserving duodenopancreatectomy was performed on 289 (75.6%) patients, while the remaining patients underwent a classic Whipple procedure (CW). The total incidence of PF was 37.7% (grade A 22.8%, grade B 11.0% and grade C 3.9%). Soft pancreatic texture (SPT) was present in 58.3% of patients who developed PF. Mortality was 4.2%. The median DFA value on the first postoperative day (DFA1) in patients who developed PF was 4520 U/L (range 350-99000 U/L) for grade A fistula (BPF) with a SPT and a diameter of the main pancreatic duct (MPD) of ≤ 3 mm. For grade B/C (CRPF), the median DFA1 value was 8501 U/L (range 377-92060 U/L) with a SPT and MPD of ≤ 3 mm. These values were significantly higher when compared to the patients who did not have PF (122; range 5-37875 U/L). The upper limit of DFA values for the first 3 postoperative days in the examined stages of PF were: DFA1 1200 U/L for the BPF and CRPF; DFA3 350 U/L for BPF and DFA3 800 U/L for CRPF. The determined values were highly significant and demonstrated a reliable diagnostic test for both BPF and CRPF. CONCLUSION: DFA1 ≥ 1200 U/L is an important predictive factor for PF of any degree. The trend of DFA3 (decrease of < 50%) compared to DFA1 is a significant factor in the differentiation of CRPF from transient BPF.

RESUMEN

BACKGROUND/AIMS: Liver resection is the gold standard in managing patients with metastatic or primary liver cancer. The aim of our study was to compare the traditional clamp-crushing technique to the radiofrequency- assisted liver resection technique in terms of postoperative liver function. METHODOLOGY: Liver function was evaluated preoperatively and on postoperative days 3 and 7. Liver synthetic function parameters (serum albumin level, prothrombin time and international normalized ratio), markers of hepatic injury and necrosis (serum alanine aminotransferase, aspartate aminotransferase and total bilirubin level) and microsomal activity (quantitative lidocaine test) were compared. RESULTS: Forty three patients completed the study (14 had clamp-crushing and 29 had radiofrequency assisted liver resection). The groups did not differ in demographic characteristics, pre-operative liver function, operative time and perioperative transfusion rate. In postoperative period, there were similar changes in monitored parameters in both groups except albumin levels, that were higher in radiofrequency-assisted liver resection group (p=0.047). CONCLUSIONS: Both, traditional clamp-crushing technique and radiofrequency assisted liver resection technique, result in similar postoperative changes of most monitored liver function parameters.

RESUMEN

INTRODUCTION: For the difference from poorly differentiated, well differentiated endocrine carcinomas of the pancreas are the tumours in whom with aggressive surgery and chemotherapy fair results can be achieved. OBJECTIVE: The aim of the study was to point out the importance of such treatment. METHODS: Over a 6-year period eight patients (seven female and one male) of average age 51 years (ranging from 23 to 71 years) were operated on for well differentiated endocrine carcinoma: six of the head and two of the tail of the pancreas. There were two functional and six nonfunctional tumours. Pain in the upper part of the abdomen in seven, mild loss in weight in two, strong heartburn in two, obstructive jaundice in three, diarrhoea in one, sudden massive bleeding from gastric varicosities due to prehepatic portal hypertension caused by pancreatic head tumour in one, and bruise in one patient were registered preoperatively. US and CT in all, angiography in one, octreoscan in two and PET scan in one patient were performed. Whipple's procedure was performed in six and distal pancreatectomy in two patients, as well as systemic lymphadenectomy in all and excision of liver secondary tumours in two patients. In the patient with massive gastric bleeding a total gastrectomy was performed first, followed by Whipple's procedure a month later. RESULTS: R0 resection was achieved in all patients. Lymph nodes metastases were found in six patients. Six patients were given chemotherapy. One patient died 3 years after surgery, seven are still alive, on average 2.5 years. A local recurrence after distal pancreatectomy that occurred 5 years after surgery was successfully reresected and the patient is on peptide-receptor radiotherapy. In other six patients there were no local recurence or distant metastases. CONCLUSION: With aggressive surgery and chemotherapy fair results can be achieved in well differentiated endocrine carcinomas of the pancreas.

RESUMEN

BACKGROUND: Cystic dystrophy in heterotopic pancreas (CDHP) is a rare condition. It has been recently reported as one of the etiologic obstructive factors of chronic pancreatitis. The aim of our study was to evaluate diagnosis and management of CDHP in the duodenal wall in a surgical series. METHODS: We retrospectively reviewed 13 patients with available clinical data. RESULTS: There were 11 male and 2 female patients, median age 42 years. The average duration of symptoms was 7.5 months. 6 of them (46%) were alcoholics, and 10 (75%) had signs of chronic pancreatitis. Almost all of them (12/13; 92%) revealed disabling pain, while 4 (31%) had associated jaundice. In 4 of 7 patients (57%), weight loss was observed. Most often the patients were suspected of having pancreatic head mass with or without signs of chronic pancreatitis. All patients underwent surgical treatment. Pathological examination showed the presence of cysts surrounded by inflammation and fibrosis in the duodenal wall, as well as the presence of chronic pancreatitis in the pancreas proper. CONCLUSIONS: Cystic dystrophy of the duodenal wall represents a significant proportion of patients undergoing surgery for chronic pancreatitis. Pancreatoduodenectomy is the best therapeutic option.
