ABSTRACT

BACKGROUND: We investigated the occluded essential vessel tributaries, both arterial and venous, occluded superior mesenteric vein and artery in rats, consequent noxious syndrome, peripherally and centrally. As therapy, we hypothesized the rapidly activated alternative bypassing pathways, arterial and venous, and the stable gastric pentadecapeptide BPC 157 since it rapidly alleviated venous occlusion syndromes. METHODS: Assessments were performed for 30 min (gross recording, venography, ECG, pressure, microscopy, biochemistry, and oxidative stress), including portal hypertension, caval hypertension, aortal hypotension, and centrally, the superior sagittal sinus hypertension; systemic arterial and venous thrombosis, ECG disturbances, MDA-tissue increase, the multiple organs lesions, heart, lung, liver, kidney and gastrointestinal tract, including brain (swelling, and cortex (cerebral, cerebellar), hypothalamus/thalamus, hippocampus lesions). Rats received BPC 157 medication (10 µg/kg, 10 ng/kg) intraperitoneally at 1 min ligation-time. RESULTS: BPC 157 rapidly activated collateral pathways. These collateral loops were the superior mesenteric vein-inferior anterior pancreaticoduodenal vein-superior anterior pancreaticoduodenal vein-pyloric vein-portal vein pathway, an alternative pathway toward inferior caval vein via the united middle colic vein and inferior mesenteric vein through the left colic vein, and the inferior anterior pancreaticoduodenal artery and inferior mesenteric artery. Consequently, BPC 157 counteracted the superior sagittal sinus, portal and caval hypertension, aortal hypotension, progressing venous and arterial thrombosis peripherally and centrally, ECG disturbances attenuated. Markedly, the multiple organs lesions, heart, lung, liver, kidney, and gastrointestinal tract, in particular, as well as brain lesions, and oxidative stress in tissues were attenuated. CONCLUSIONS: BPC 157 therapy rapidly recovered rats, which have complete occlusion of the superior mesenteric vein and artery.

ABSTRACT

Background. Gastric pentadecapeptide BPC 157 therapy in rats compensated irremovable occlusion of various vessels and counteracted the consequent multiorgan dysfunction syndromes by activation of the corresponding collateral bypassing loops. Thus, we used BPC 157 therapy against the irremovable occlusion of the end of the superior mesenteric vein. Methods. Assessments, for 30 min (gross recording, venography, ECG, pressure, microscopy, biochemistry, and oxidative stress) include the portal and caval hypertension, aortal hypotension, and centrally, the superior sagittal sinus hypertension, systemic arterial and venous thrombosis, ECG disturbances, MDA-tissue increase, and heart, lung, liver, kidney and gastrointestinal tract, in particular, and brain (cortex (cerebral, cerebellar), hypothalamus/thalamus, hippocampus) lesions. Rats received BPC 157 medication (10 µg/kg, 10 ng/kg) intraperitoneally at 1 or 15 min ligation time. Results. BPC 157 rapidly activated the superior mesenteric vein-inferior anterior pancreati-coduodenal vein-superior anterior pancreaticoduodenal vein-pyloric vein-portal vein pathway, reestablished superior mesenteric vein and portal vein connection and reestablished blood flow. Simultaneously, toward inferior caval vein, an additional pathway appears via the inferior mesenteric vein united with the middle colic vein, throughout its left colic branch to ascertain alternative bypassing blood flow. Consequently, BPC 157 acts peripherally and centrally, and counteracted the intracranial (superior sagittal sinus), portal and caval hypertension, aortal hypotension, ECG disturbances attenuated, abolished progressing venous and arterial thrombosis. Additionally, BPC 157 counteracted multiorgan dysfunction syndrome, heart, lung, liver, kidney and gastrointestinal tract, and brain lesions, and oxidative stress in tissues. Conclusion. BPC 157 therapy may be specific management also for the superior mesenteric vein injuries.

ABSTRACT

Gastric pentadecapeptide BPC 157 therapy counteracts multiple organ dysfunction syndrome in rats, which have permanent occlusion of the superior mesenteric artery close to the abdominal aorta. Previously, when confronted with major vessel occlusion, its effect would rapidly activate collateral vessel pathways and resolve major venous occlusion syndromes (Pringle maneuver ischemia, reperfusion, Budd-Chiari syndrome) in rats. This would overwhelm superior mesenteric artery permanent occlusion, and result in local, peripheral, and central disturbances. Methods: Assessments, for 30 min (gross recording, angiography, ECG, pressure, microscopy, biochemistry, and oxidative stress), included the portal hypertension, caval hypertension, and aortal hypotension, and centrally, the superior sagittal sinus hypertension; systemic arterial and venous thrombosis; ECG disturbances; MDA-tissue increase; and multiple organ lesions and disturbances, including the heart, lung, liver, kidney, and gastrointestinal tract, in particular, as well as brain (cortex (cerebral, cerebellar), hypothalamus/thalamus, hippocampus). BPC 157 therapy (/kg, abdominal bath) (10 µg, 10 ng) was given for a 1-min ligation time. Results: BPC 157 rapidly recruits collateral vessels (inferior anterior pancreaticoduodenal artery and inferior mesenteric artery) that circumvent occlusion and ascertains blood flow distant from the occlusion in the superior mesenteric artery. Portal and caval hypertension, aortal hypotension, and, centrally, superior sagittal sinus hypertension were attenuated or eliminated, and ECG disturbances markedly mitigated. BPC 157 therapy almost annihilated venous and arterial thrombosis. Multiple organ lesions and disturbances (i.e., heart, lung, liver, and gastrointestinal tract, in particular, as well as brain) were largely attenuated. Conclusions: Rats with superior mesenteric artery occlusion may additionally undergo BPC 157 therapy as full counteraction of vascular occlusion-induced multiple organ dysfunction syndrome.

ABSTRACT

The aim of the study was to explore predictive value of the ALBI, PALBI and MELD scores on survival in patients resected for hepatocellular carcinoma with compensated liver cirrhosis and no macrovascular infiltration. In this retrospective study, longitudinal survival analysis was performed. We analyzed patient/tumor characteristics and MELD, ALBI and PALBI scores as liver function tests for predicting survival outcome. Survival was analyzed from the date of liver resection until death, liver transplantation, or end of follow-up. Patients were stratified for age, cirrhosis etiology, presence of esophageal varices, hepatocellular carcinoma stage, microvascular invasion, histologic differentiation, and resection margins. We identified 38 patients (alcoholic cirrhosis in 84.2% of patients) resected over an 8-year period. Median preoperative MELD score was 8, ALBI score -2.63, and PALBI score -2.38. During the follow-up period, 24 patients died. Estimated median survival time was 36 months. Microvascular invasion was observed in 33 patients. Higher ALBI score was associated with 23.1% higher relative risk of death. PALBI score was associated with 12.1% higher relative risk of death, whereas MELD score was not associated with the risk of death. In conclusion, ALBI score demonstrated significant predictive capabilities for survival in patients with compensated cirrhosis resected for hepatocellular carcinoma.

ABSTRACT

AIM: To compare and evaluate the hepatoprotective effect of remote ischemic preconditioning (RIPC) with local ischemic preconditioning (LIPC) of the liver during human liver resections. METHODS: A prospective, single-centre, randomised control trial was conducted in the Clinical Hospital "***" from April 2017 to January 2018. A total of 60 patients, who underwent liver resection due to colorectal cancer liver metastasis, were randomised to one of three study arms: 1) a RIPC group, 2) an LIPC group and 3) a control group (CG) in which no ischemic preconditioning was done before liver resection. The hepatoprotective effect was evaluated by comparing serum transaminase levels, bilirubin levels, albumin, and protein levels, coagulograms and through pathohistological analysis. The trial was registered on ClinicalTrials.gov (NCT****). RESULTS: Significant differences were found in serum levels of liver transaminases and bilirubin levels between thegroups, the highest level in the CG and the lowest level in the LIPC group. Levels of cholinesterase were also significantly higher in the LIPC group. Pathohistological findings graded by the Rodriguez score showed favourable changes in the LIPC and RIPC groups versus the CG. CONCLUSION: Strong evidence supports the hepatoprotective effect of RIPC and LIPC preconditioning from an ischemia-reperfusion injury of the liver. Better synthetic liver function preservation in these two groups supports this conclusion.

ABSTRACT

Introduction Despite some new treatment possibilities, the improvement in survival rate for hepatocellular carcinoma (HCC) patients is still poor due to late diagnosis. The aim of this study was to investigate the diagnostic sensitivity and specificity of protein induced by vitamin K absence or antagonist-II (PIVKAII), Glypican-3 (GP3), Cystatin B (CSTB), squamous cell carcinoma antigen 1 (SCCA1) and hepatocyte growth factor (HGF) as potential tumour markers for HCC in patients with alcoholic liver cirrhosis (ALC) using imaging techniques (MSCT and MRI) as reference standards. Patients and methods Eighty-three participants were included: 20 healthy volunteers, 31 patients with ALC and 32 patients with HCC. Peripheral blood sampling was performed for each participant, and serum concentrations of PIVKAII, GP3, CSTB, SCCA1 and HGF were determined using commercial ELISA kits. Results Only serum concentrations of PIVKAII were significantly higher in HCC patients as compared with ALC and healthy controls (cut-off: 2.06 µg/L; AUC: 0.903), whereas individual diagnostic performance of other individual compounds was inadequate. The 'best' combination of tumour markers in our study includes all tested markers with AUC of 0.967. Conclusion While novel diagnostic tumour markers are urgently needed, the examined potential tumour markers, with the exception of PIVKAII seem to be inadequate for diagnosing HCC in ALC. Furthermore, probably the future is in finding the best optimal combination of tumour markers for diagnosing HCC based on cost-effectiveness.

ABSTRACT

AIM: To assess the diagnostic value of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in lung cancer (LC). We compared the ratios between healthy participants and all LC patients, as well patients with different pathohistological LC subtypes. METHODS: We retrieved the data on neutrophil, lymphocyte, and platelet levels in 449 patients with different pathohistological LC subtypes (non-small cell LC, small-cell LC, atypical or metastatic LC, neuroendocrine, and sarcomatoid carcinoma) and 47 healthy controls. NLR and PLR were calculated by dividing the absolute number of neutrophils or platelets with the absolute number of lymphocytes. RESULTS: There were significant differences in both NLR and PLR (P<0.001) between all LC patients and the control group, but there were no differences between patients with different LC subtypes. Reciever operating characteristics analysis for NLR showed the optimal cut-off value of 2.71, with a sensitivity of 77.05% and specificity of 87.23%. The optimal cut-off value for PLR was 182.31, with a sensitivity of 51.09% and specificity of 91.49%. CONCLUSION: The results showed that the NLR and PLR may have added value in the early diagnosis of LC, but further research is needed to confirm these results.

ABSTRACT

The purpose of this study was to investigate prognostic significance of Dopamine and cAMP-Regulated neuronal Phosphoprotein 32 (DARPP-32) expression in primary colorectal cancer. The study material consisted of clinical and histopathological data of 100 patients operated for colorectal cancer between 1994 and 1997. For immunohistochemical analysis, specific rabbit antibodies for DARPP-32 were used and the percentage of stained tumor cells was calculated under gross magnification (400 times) on a sample of 500 tumor cells. DARPP-32 expression in the primary tumor was significantly greater in patients with distant metastases compared to patients with no distant metastases (p=0.002). In multivariate regression analysis, DARPP-32 expression in the primary tumor was a significant predictor of distant metastases. With a cut-off point of 76.5%, DARPP-32 expression in the primary tumor significantly influenced both overall and disease free survival, especially for Dukes A and B patients (p=0.037). The results of this study indicate that DARPP-32 may be a potential marker of worse prognosis and a valuable tool for managing further adjuvant treatment in patients with stages Dukes A and B colorectal cancer.

ABSTRACT

Echinococcal cyst of the spleen is usually a result of infection with the parasite Echinococcus granulosus. The spleen is the third most frequent localization of echinococcus after liver and lungs. Partial laparoscopic pericystectomy can be done without the loss of blood and scattering of scolexes with spleen preservation and conservation of its immune function. We present the patient with a large (1 8 x 16 x 12 cm) echinococcal cyst of the spleen that compressed the surrounding organs (stomach, transverse colon, pancreas and left kidney), and prevented normal passage causing vomiting after every meal. In this patient, PAIR procedure (puncture, aspiration, injection, reaspiration) and conservative treatment was attempted on several occasions without success. Finally, laparoscopic partial pericystectomy was performed, evacuating the contents of the cyst. The surgery lasted 120 minutes. Postoperatively the patient was without complications. Hospitalization lasted five days. Six months later, the patient is without problems. These echinococcus cysts of the spleen cannot be solved using PAIR technique and conservative treatment. Laparoscopic partial pericystectomy is a better solution than open surgery due to less trauma to the patient, especially in elderly people.

ABSTRACT

Gallbladder cancer is the fifth most common cancer involving gastrointestinal tract, but it is the most common malignancy of the biliary tract, accounting for 80-95% of biliary tract cancers. This tumor is a highly lethal disease with an overall 5-year survival of less than 5% and mean survival mere than 6 months. An early diagnosis is essential as this malignancy progresses silently with a late diagnosis. The percentage of patients diagnosed to have gallbladder cancer after simple cholecystectomy for presumed gallbladder stone disease is 0.5-1.5%. Patients with preoperative suspicion of gallbladder cancer should not be treated by laparoscopy. Epidemiological studies have identified striking geographic and ethnic disparities-inordinately high occurrence in American Indians, elevated in Southeast Asia, yet quite low elsewhere in the Americas and the world. Environmental triggers play a critical role in eliciting cancer developing in the gallbladder, best exemplified by cholelithiasis and chronic inflammation from biliary tract and parasitic infections. Improved imaging modalities and improved radical aggressive surgical approach in the last decade has improved outcomes and helped prolong survival in patients with gallbladder cancer. The overall 5-year survival for patients with gallbladder cancer who underwent R0 curative resection was from 21% to 69%. In the future, the development of potential diagnostic markers for disease will yield screening opportunities for those at risk either with ethnic susceptibility or known anatomic anomalies of the biliary tract.

ABSTRACT

Many clinical and preclinical studies demonstrated that measurements of liver hemodynamic [Doppler perfusion index (DPI)] may be used to accurately diagnose and predict liver metastases from primary colorectal cancer in a research setting. However, Doppler measurements have some serious limitations when applied to general population. Ultrasound is very operator-dependent, and requires skilled examiners. Also, many conditions may limit the use of Doppler ultrasound and ultrasound in general, such as the presence of air in digestive tract, cardiac arrhythmias, vascular anomalies, obesity and other conditions. Therefore, in spite of the results from clinical studies, its value may be limited in everyday practice. On the contrary, scientific research of the DPI in detection of liver metastases is of great importance, since current research speaks strongly for the presence of systemic vasoactive substance responsible for observed hemodynamic changes. Identification of such a systemic vasoactive substance may lead to the development of a simple and reproducible laboratory test that may reliably identify the presence of occult liver metastases and therefore increase the success of adjuvant chemotherapy through better selection of patients. Further research in this subject is therefore of great importance.

ABSTRACT

The laparoscopic liver resection (LLR) represents a new pathway in hepatic surgery. Several studies have reported its application in both malignant and benign liver diseases. The most common liver resections performed laparoscopically are wedge, segmental resections and metastasectomy; although in large centers the laparoscopic right and left hepatectomies have begun to perform more frequently. We report the initial experience in LLRs at our department including a case of the first laparoscopic left lateral liver bisegmentectomy performed in patient with follicular nodular hyperplasia and the 15 cases of wedge laparoscopic resections of echinococcic liver cysts. According to literature the mortality rate in LLRs is up to 0.3% and morbidity rate up to 10.5%. The most common cause of the death is liver failure, while the most frequent complication is the bile leakage. Advantages for patients include smaller incisions, less blood loss, and shorter lengths of hospital stay. The LLRs in experienced hands were shown to be safe with acceptable morbidity and mortality for both minor and major hepatic resections in benign and malignant diseases.

ABSTRACT

A surgical resection is the only curative method in the therapy of colorectal carcinoma and liver metastases. Along with the development of interventional radiological techniques the indications for surgery widen. The number of metastases and patients age should not present a contraindication for surgical resection. However, there are still some doubts concerns what to resect first in cases of synchronous colorectal carcinoma and liver metastases and how to ensure the proper remnant liver volume in order to avoid postoperative liver failure and achieve the best results. Through this review the surgical therapy of colorectal carcinoma and liver metastases was revised in the setting of "liver-first" approach and the problem of ensuring of remnant liver volume.

ABSTRACT

Laparoscopic surgery for hepatic echinococcosis is a technically difficult and demanding surgical procedure even for the most experienced abdominal surgeon. Surgery is performed after the conservative treatment with albendazole for 28 days. We report a case of laparoscopic partial pericystectomy with biliostasis and omentoplasty in a patient with two previously open surgeries (laparotomies)--right subcostal laparotomy for acute inflammation of the gallbladder and right pararectal laparotomy for perforated gangrenous appendix. The patient underwent extensive laparoscopic adhesiolysis due to pronounced intra-abdominal adhesions to gain access to a large hydatid cyst with the diameter of 11 cm. Laparoscopic surgery is much less traumatic to the patient with a better cosmetic effect.

ABSTRACT

There are several options for surgical treatment of large bowel obstruction caused by cancer, depending on location of obstruction, intraoperative local findings (perforation, peritonitis, bowel dilatation proximal to obstruction) and patients' condition. Resection and anastomosis as one stage surgery would be prefered procedure. Anastomotic leakage, on the other hand, highly elevates risk of mortality and mobidity. The most important question is whether to, in resectable cases, perform primary resection with anastomosis or not. This study was retrospective and included 40 patients that have undergone emergency surgery for large bowel obstruction caused by cancer. According to whether resection and anastomosis was made at initial surgery or not, patients were grouped in group A (N = 18) and group B (N = 21), respectively. We have analysed the type of surgical procedure, days of hospitalization, mortality, anastomotic leakeage, wound infection and other postoperative complications. Our results show that there is no major difference in mortality and morbidity in these two groups, suggesting that for selected patients primary resection and anastomosis is a safe option of tratment with acceptable risk. Since there are no strict guidelines or scorring system which would point the tratment option the decision about the choice of procedure still remains the burden of surgeon and depends on its experience and subspeciality. Our experience recomends primary resection and anastomosis except in cases of bowel perforation on tumor site, in cases of extreme dilatation and atony of bowel proximal to obstruction site and severe hypoproteinemia and anemia.

ABSTRACT

PURPOSE: An inadequate closure of the appendiceal stump can lead to intra-abdominal surgical site infections. The aim of this study was to assess the efficiency of different closure techniques by focusing on the intraoperative and postoperative complications versus cost. METHODS: From June 2011 to June 2013, 333 patients from two different hospitals undergoing laparoscopic appendectomy were included in this study. The patients were divided into two groups based on the technique used for appendiceal stump closure: there were 104 patients in the stapler group and 229 in the loop group. RESULTS: Among the 333 patients who underwent laparoscopic appendectomy, there were two (0.6%) intraoperative complications and 22 (6.6%) postoperative complications. There were no significant differences between the groups with respect to the intraoperative and postoperative complications. The length of the operation was 7 min shorter when the endoloop was used (p = 0.014). The mean costs of the operation were significantly lower when the loop was used ( 554.93) compared to the stapler ( 900.70) (p = 0.000). CONCLUSIONS: There is no clinical evidence supporting the routine use of endoscopic staplers. The appendiceal stump can be secured safely with the use of endoloops in the majority of patients. Surgeons have to be more selective when choosing how to perform closure, and an endostapler should be used only in cases where it is clinically indicated.

ABSTRACT

Primary intraabdominal malignant mesenchymal tumors are very rare. There are just few cases of intraabdominal visceral malignant fibrous histiocytoma in the literature. We report a case of primary malignant fibrous histiocytoma of the spleen in a 57-year-old man, with a recurrence eight years after the splenectomy. After the initial surgery the patient was without complaints, and refused to receive chemotherapy or radiotherapy. Eight years after the surgery the patient reported due to general weakness and malaise when the diagnosis of disease relapse was established. Radical surgery was performed although the tumor involved large curvature of the stomach, left crus of the diaphragm, splenic flexure of the colon and tail of pancreas. Four months after the surgery patient died. To the best of our knowledge, to date, only 18 cases have been reported in the literature, describing malignant fibrous histiocytoma of the spleen.

ABSTRACT

This study compared sensitivity and specificity of multidetector-row computed tomography and duplex Doppler ultrasonography in detecting atherosclerotic carotid plaques complicated with intraplaque hemorrhage. Carotid plaques from 50 patients operated for carotid artery stenosis were analyzed. Carotid endarterectomy was performed within one week of diagnostic evaluation. Results of multidetector-row computed tomography and duplex Doppler ultrasonography diagnostic evaluation were compared with results of histological analysis of the same plaque areas. American Heart Association classification of atherosclerotic plaques was applied for histological classification. Median tissue density of carotid plaques complicated with intraplaque hemorrhage was 14.7 Hounsfield units. Median tissue density of noncalcified segments of uncomplicated plaques was 54.3 Hounsfield units (p = 0.00003). The highest tissue density observed for complicated plaques was 31.8 Hounsfield units. Multidetector-row computed tomography detected plaques complicated with hemorrhage with sensitivity of 100% and specificity of 70.4%, with tissue density of 33.8 Hounsfield units as a threshold value. Duplex Doppler ultrasonography plaque analysis based on visual in-line classification showed sensitivity of 21.7% and specificity of 89.6% in detecting plaques complicated with intraplaque hemorrhage. Multidetector-row computed tomography showed a very high level of sensitivity and a moderate level of specificity in detecting atherosclerotic carotid plaques complicated with hemorrhage. Duplex Doppler ultrasonography plaque analysis based on visual in-line classification showed a low level of sensitivity and a moderate-high level of specificity in detecting atherosclerotic carotid plaques complicated with hemorrhage.

ABSTRACT

Stapled hemorrhoidectomy (SH) and Ligasure hemorrhoidectomy (LH) are standard for hemorrhoidal disease treatment, but the surgical principle is different. This randomized clinical trial compared the 2 methods. We included 98 patients with grade 3 hemorrhoidal disease: 46 patients treated by SH and 52 patients by LH. Incidence of complications, recurrence, postoperative pain, wound healing time, and time off everyday activity were observed. The follow-up period was 24 months. We found that LH has a significantly shorter wound healing time. The recurrence rate and the overall postoperative complication rate was higher after SH but not significantly (recurrence LH vs. SH: 1.9% vs. 11.1%; complications LH vs. SH: 13.5% vs. 23.9%). Postoperative pain level, analgesic consumption, and time off everyday activity were practically the same in both groups. Both procedures can be used to treat grade 3 hemorrhoidal disease with the same efficacy, but analysis of recurrence after SH is necessary.
