Abstract
PURPOSE The aim of this randomized study was to compare the complications and perioperative outcome of three different techniques of laparoscopic cholecystectomy (LC). Changes in the liver function test after LC techniques were investigated. Also, we compared the degree of postoperative adhesions and histopathological changes of the liver bed. METHODS Thirty rabbits were divided into three groups: group A) Fundus-first technique by Hook dissecting instrument and Roeder Slipknot applied for cystic duct (CD) ligation; group B) conventional technique by Maryland dissecting forceps and electrothermal bipolar vessel sealing (EBVS) for CD seal; group C) conventional technique by EBVS for gallbladder (GB) dissection and CD seal. RESULTS Group A presented a longer GB dissection time than groups B and C. GB perforation and bleeding from tissues adjacent to GB were similar among tested groups. Gamma-glutamyl transferase and alkaline phosphatase levels increased (p ≤ 0.05) on day 3 postoperatively in group A. By the 15th postoperative day, the enzymes returned to the preoperative values. Transient elevation of hepatic transaminases occurred after LC in all groups. Group A had a higher adherence score than groups B and C and was associated with the least predictable technique. CONCLUSIONS LC can be performed using different techniques, although the use of EBVS is highly recommended.

Abstract
Cell-free DNA (cfDNA) concentrations from patients with cancer are often elevated compared with those of healthy controls, but the sources of this extra cfDNA have never been determined. To address this issue, we assessed cfDNA methylation patterns in 178 patients with cancers of the colon, pancreas, lung, or ovary and 64 patients without cancer. Eighty-three of these individuals had cfDNA concentrations much greater than those generally observed in healthy subjects. The major contributor of cfDNA in all samples was leukocytes, accounting for ∼76% of cfDNA, with neutrophils predominating. This was true regardless of whether the samples were derived from patients with cancer or the total plasma cfDNA concentration. High levels of cfDNA observed in patients with cancer did not come from either neoplastic cells or surrounding normal epithelial cells from the tumor's tissue of origin. These data suggest that cancers may have a systemic effect on cell turnover or DNA clearance. SIGNIFICANCE The origin of excess cfDNA in patients with cancer is unknown. Using cfDNA methylation patterns, we determined that neither the tumor nor the surrounding normal tissue contributes this excess cfDNA-rather it comes from leukocytes. This finding suggests that cancers have a systemic impact on cell turnover or DNA clearance. See related commentary by Thierry and Pisareva, p. 2122.

Xiao F, Qiu XF, You CW, Xie FP, Cai YY. Influence of liver function after laparoscopy-assisted vs totally laparoscopic gastrectomy. World J Gastrointest Surg 2023; 15:859-870. [PMID: 37342845 PMCID: PMC10277945 DOI: 10.4240/wjgs.v15.i5.859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 03/11/2023] [Accepted: 04/04/2023] [Indexed: 05/26/2023] Open
Abstract
BACKGROUND Previously, some studies have proposed that total laparoscopic gastrectomy (TLG) is superior to laparoscopic-assisted gastrectomy (LAG) in terms of safety and feasibility based on the related intraoperative operative parameters and incidence of postoperative complications. However, there are still few studies on the changes in postoperative liver function in patients undergoing LG. The present study compared the postoperative liver function of patients with TLG and LAG, aiming to explore whether there is a difference in the influence of TLG and LAG on the liver function of patients.
AIM To investigate whether there is a difference in the influence of TLG and LAG on the liver function of patients.
METHODS The present study collected 80 patients who underwent LG from 2020 to 2021 at the Digestive Center (including the Department of Gastrointestinal Surgery and the Department of General Surgery) of Zhongshan Hospital affiliated with Xiamen University, including 40 patients who underwent TLG and 40 patients who underwent LAG. Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), γ-glutamyltransferase (GGLT), total bilirubin (TBIL), direct bilirubin (DBIL) and indirect bilirubin (IBIL), and other liver function-related test indices were compared between the 2 groups before surgery and on the 1st, 3rd, and 5th d after surgery.
RESULTS The levels of ALT and AST in the 2 groups were significantly increased on the 1st to 2nd postoperative days compared with those before the operation. The levels of ALT and AST in the TLG group were within the normal range, while the levels of ALT and AST in the LAG group were twice as high as those in the TLG group (P < 0.05). The levels of ALT and AST in the 2 groups showed a downward trend at 3-4 d and 5-7 d after the operation and gradually decreased to the normal range (P < 0.05). The GGLT level in the LAG group was higher than that in the TLG group on postoperative days 1-2, the ALP level in the TLG group was higher than that in the LAG group on postoperative days 3-4, and the TBIL, DBIL and IBIL levels in the TLG group were higher than those in the LAG group on postoperative days 5-7 (P < 0.05). No significant difference was observed at other time points (P > 0.05).
CONCLUSION Both TLG and LAG can affect liver function, but the effect of LAG is more serious. The influence of both surgical approaches on liver function is transient and reversible. Although TLG is more difficult to perform, it may be a better choice for patients with gastric cancer combined with liver insufficiency.

Macrophage activation marker sCD163 is associated with liver injury and hepatic insulin resistance in obese patients before and after Roux-en-Y gastric bypass. Physiol Rep 2022; 10:e15157.

Abstract
BACKGROUND Macrophages are associated with metabolic complications to obesity including fatty liver disease and impaired hepatic and muscle insulin sensitivity (IS). Bariatric surgery induces weight loss and improves IS. We investigated associations between the macrophage activation marker soluble (s)CD163, alanine-aminotransferase (ALT), and IS before and after Roux-en-Y Gastric Bypass (RYGB). METHODS We analyzed sCD163 from 10 type 2 diabetes (T2D) and 10 obese patients with normal glucose tolerance (NGT) undergoing RYGB for associations with hepatic, adipose tissue, and muscle IS and ALT after 1-week, 3, and 12 months postoperatively. IS was evaluated by hyperinsulinemic-euglycemic clamp in combination with glucose tracer technique. RESULTS Preoperative sCD163 correlated with ALT (r = 0.58, p = 0.007) and tended to associate inversely with hepatic (r = -0.39, p = 0.1) and adipose tissue (r = -0.39, p = 0.09), but not muscle IS. Following RYGB, sCD163 decreased significantly in all patients. The decrease in sCD163 during the first 3 months correlated inversely with the improvement of hepatic IS (r = -0.65, p = 0.01) and tended to be associated with changes in muscle IS (r = -0.45, p = 0.09). After 3 months sCD163 remained associated with ALT (r = 0.75, p < 0.001) and inversely with hepatic IS (r = -0.39, p = 0.1), but not muscle or adipose tissue IS. One year after RYGB, sCD163 correlated with ALT (r = 0.61, p = 0.007), but not with hepatic, adipose tissue, or muscle IS. CONCLUSION Macrophage activation is associated with liver injury and hepatic IS in obese patients. Improvements in these measures correlate during the first 3 months following RYGB, supporting a link between macrophages and hepatic IS in severe obesity and diabetes.

Abstract
OBJECTIVES In this study, we use a national database to evaluate post-transcatheter (TAVR)/surgical aortic valve replacement (SAVR) outcomes stratified using chronic liver disease (CLD). BACKGROUND In patients undergoing TAVR and SAVR, the surgical risks should be optimized; this includes evaluating hepatic diseases that may pose an operative risk. METHODS 2011-2017 National Inpatient Sample was used to select in-hospital TAVR and SAVR cases, which were stratified according to CLD (cirrhosis, hepatitis B/C, alcoholic/fatty/nonspecific liver disease). The cases-controls were matched using propensity score matching and compared with various endpoints. RESULT After matching for demographics and comorbidities, for TAVR, 606 and 1818 were with or without CLD; for SAVR, 1353 and 4059 were with and without CLD. In TAVR, there was no differences in mortality (2.81% vs. 2.75% OR 1.02 95% CI 0.58-1.78) or length of stay (6.29 vs. 6.44d p = 0.29), and CLD-present patients had marginally increased costs ($228,415 vs. $226,682 p = 0.048). There were no differences in complications. In multivariate, there was no difference in mortality (aOR 1.02 95% CI 0.58-1.79). In SAVR, CLD patients had higher mortality (7.98% vs. 3.23% OR 2.60 95% CI 2.00-3.38), length of stay (13.3 vs. 11.3 days p < 0.001), and costs ($273,487 vs. $238,097 p < 0.001). CLD patients also had increased respiratory failure (9.02% vs. 7.19% OR 1.28 95% CI 1.03-1.59) and bleeding (8.43% vs. 6.33% OR 1.36 95% CI 1.08-1.71). In multivariate, CLD had higher mortality (aOR 2.60 95% CI 2.00-3.38). CONCLUSION CLD is associated with higher mortality and complications in patients undergoing SAVR; however, no correlation was found in patients undergoing TAVR.

Abstract
OBJECTIVE The aim of this study was to investigate whether there was a difference in laparoscopic sleeve gastrectomy (LSG) performed with either 10 mmHg or 13 mmHg intraabdominal pressures. Effects of these pressures on the internal jugular vein (IJV) diameter and flow along with the liver and kidney function tests were evaluated. MATERIALS AND METHODS The patients were divided into two groups with respect to the intraabdominal pressure performed during LSG (either 10 or 13 mmHg). The patients' age, comorbidities, surgical history, height, weight, body mass index, family history, duration of surgery, length of hospital stay, serum liver and kidney function tests (Urea, creatinine, Aspartate transaminase, Alanine transaminase, Gamma-glutamyltransferase, Alkaline phosphatase, bilirubin) and the right IJV diameter and flow measured by Duplex ultrasound before intubation (t1), 10 min after insufflation (t2), and at the end of insufflation (t3) were recorded. RESULTS Preoperative and postoperative kidney and liver function values of the patients in both groups were within the reference range. In both groups, there was a significant decrease in the IJV diameter and flow measurement values at t2 compared to t1, and a significant increase was observed at t3 compared to t2 (p < 0.05). The mean IJV diameter and flow were significantly higher in the 10 mmHg pressure group compared to the 13 mmHg group (p < 0.05). CONCLUSION Neither of the peak pressures performed intraabdominal during LSG caused an adverse effect on liver or kidney functions. Our study emphasizes that low insufflation pressure does not have an advantage in terms of liver and kidney functions. But laparoscopic sleeve gastrectomy with low intra-abdominal pressure may be beneficial especially in patients who require central vein catheterization during the operation. We consider that LSG performed with CO2 pneumoperitoneum at 10 mmHg is a safe, effective and feasible method that can facilitate the insertion of the intraoperative central venous catheter due to lesser charges in the IJV diameter and flow compared to the standard technique.

Abstract
Objective: To compare the safety and feasibility of T-tube drainage and primary suture after laparoscopy combined with choledochoscopy in the treatment of secondary choledocholithiasis. Methods: The clinical data of patients who underwent laparoscopic choledochoscopy combined with choledochoscopic common bile duct exploration (LCBDE) for secondary choledocholithiasis from June 2015 to June 2020 were analyzed retrospectively. According to the different treatment method of common bile duct (CBD) incision, the patients were divided into a T-tube drainage group and a primary suture group. The preoperative clinical characteristics, results of preoperative liver function tests (LFTs), LFTs on the first day after the operation and the fourth day after the operation, operation time, intraoperative bleeding, postoperative complications, and times of postoperative hospital stay were compared between the two groups. Results: There was no significant difference in preoperative clinical data, preoperative LFTs, and postoperative complications between the two groups (P > .05). However, primary suture demonstrated significant advantages (P < .05) in terms of the operation time, intraoperative blood loss, postoperative hospital stay, and other related factors. Bilirubin levels on the first day after the operation and the fourth day after the operation between the two groups suggested that T-tube drainage reduces bilirubin in the short term, but that long-term bilirubin draining is similar between the two strategies. Univariate and multivariate analyses showed that choledochal diameter less than 8 mm was an independent risk factor for bile leakage. Conclusions: Laparoscopy combined with intraoperative choledochoscopic CBD exploration is superior to T-tube drainage in terms of the operation time, intraoperative blood loss, and postoperative hospital stay. The ability of reducing bilirubin by traditional T-tube drainage is indeed better than that of primary suture in the early stage after operation, but there is no difference in long-term outcome between the two groups. Choledochal diameter ≤8 mm was an independent risk factor for bile leakage. To summarize, LCBDEs primary suture for secondary choledocholithiasis is safe and feasible.

Abstract
Acute myocardial infarction triggers a strong inflammatory response in the affected cardiac tissue. New therapeutic tools based on stem cell therapy may modulate the unbalanced inflammation in the damaged cardiac tissue, contributing to the resolution of this pathological condition. The main goal of this study was to analyze the immunomodulatory effects of cardiosphere-derived cells (CDCs) and their extracellular vesicles (EV-CDCs), delivered by intrapericardial administration in a clinically relevant animal model, during the initial pro-inflammatory phase of an induced myocardial infarction. This effect was assessed in peripheral blood and pericardial fluid leukocytes from infarcted animals. Additionally, cardiac functional parameters, troponin I, hematological and biochemical components were also analyzed to characterize myocardial infarction-induced changes, as well as the safety aspects of these procedures. Our preclinical study demonstrated a successful myocardial infarction induction in all animals, without any reported adverse effect related to the intrapericardial administration of CDCs or EV-CDCs. Significant changes were observed in biochemical and immunological parameters after myocardial infarction. The analysis of peripheral blood leukocytes revealed an increase of M2 monocytes in the EV-CDCs group, while no differences were reported in other lymphocyte subsets. Moreover, arginase-1 (M2-differentiation marker) was significantly increased in pericardial fluids 24 h after EV-CDCs administration. In summary, we demonstrate that, in our experimental conditions, intrapericardially administered EV-CDCs have an immunomodulatory effect on monocyte polarization, showing a beneficial effect for counteracting an unbalanced inflammatory reaction in the acute phase of myocardial infarction. These M2 monocytes have been defined as “pro-regenerative cells” with a pro-angiogenic and anti-inflammatory activity.

Abstract
Purpose: Laparoscopic cholecystectomy is generally performed with the help of monopolar cautery. We aimed to reveal the effect of monopolar cautery use on liver damage in this study. Method: Data of patients who underwent elective cholecystectomy between January 2016 and April 2020 were collected retrospectively. The patients were divided into two groups according to the surgical technique as hook dissection (HD) and scissor dissection (SD). The amount of increase in the preoperative and postoperative alanine aminotransferase (ALT) and aspartate aminotransferase (AST) values of the patients was compared between the two groups. Findings: Over 970 patients were included in the study. The changes in pre-post ALT and AST values were statistically significantly different between the HD (n=469) and SD (n=501) groups (p<0.001; p0.001). ALT (26 (−25, 338)) and AST (27 (−23, 444)) changes in the HD method were statistically significantly higher than ALT (11 (−16, 371)) and AST (10.8 (−37, 617)) changes in the SD method. Results: ALT and AST values increase after all laparoscopic cholecystectomies. Although the increase in ALT and AST in the HD patients is statistically significant when compared to the SD group, both methods of laparoscopic cholecystectomy can be safely performed because they do not cause permanent liver injury.

Abstract
Introduction Laparoscopic cholecystectomy has been known as one of the most important prevalent and minimally invasive surgeries in medicine. Aim The aim here was to investigate the changes in liver enzymes and bilirubin levels after laparoscopic cholecystectomy in patients diagnosed with chronic cholecystitis. Methods This cross-sectional study was conducted at Poursina Hospital (Rasht, Iran) and 128 patients who met both inclusion and exclusion criteria were enrolled for further investigations. After collecting the patients' bio-demographic information, levels of serum alkaline phosphatase, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, and bilirubin were checked before laparoscopic cholecystectomy and 24 (post-op 1) and 48 (post-op 2) h after laparoscopic cholecystectomy. Results No significant difference was found in the serum levels of ALP in post-op 1 and 2 compared both to each other and to the baseline (P>0.05). Regarding AST and ALT, there was a significant increase in post-op 1 and 2 compared to their baseline values (P<0.05). However, the difference between post-op 1 and post-op 2 was not significant for these outcomes. Compared to baseline levels, LDH had a significant increase after post-op 2 (P=0.001); but not after post-op 1 (P >0.05). Moreover, total bilirubin levels showed significant increases at post-op 1 and post-op 2 from the baseline and also in comparison with each other (P < 0.05). Conclusion Our results demonstrated a transient increase in liver function tests and bilirubin after laparoscopic cholecystectomy.

Abstract
Deferasirox (DFX) was formulated into oil-in-water microemulsions in the presence of pluronicto improve its oral bioavailability. The size of the DFX-loadedmicroemulsions system measured by dynamic light scattering (DLS) was about 9 nm. The anti-proliferative and anti-lipid peroxidation effects of DFX and DFX-loaded microemulsions were assessed on Human umbilical vein endothelial (HUVEC) cells. Our in vitro results showed that HUVEC cells are more susceptible to free DFX as compared to DFX-loaded microemulsions. Although both free and encapsulated DFX attenuated FeCl3-induced lipid peroxidation, after 6 and 12 h treatment, DFX-loaded microemulsions did not appear a better ameliorator than DFX. To compare the in vivo efficacy of free DFX and DFX-loaded microemulsions in iron- intoxicated rats, the animals were orally administered with 25 mg/kg DFX, or 25 mg/kg DFX microemulsions, respectively. In vivo gavage handling of free DFX significantly increased serum biochemical parameters. There was also a significant increase in lipid peroxidation in rats who received free DFX compared to those in the control rats. Treatment with DFX-loaded microemulsions restored the elevated levels of serum AST, ALT, and creatinine levels and also reduced liver MDA content. Histopathological analysis of renal and hepatic tissues was in line with the biochemical results. In conclusion, DFX-loaded microemulsions induce less toxicity than free DFX and appear a more desirable and safer drug carrier in combating the iron-overload complications. Theoretical simulations are performed to get better insight regarding interactions between DFX and surfactant F127.

Abstract
The risk of poor post-operative outcome and the benefits of surgical resection as a curative therapy require careful assessment by the clinical care team for patients with primary and secondary liver cancer. Advances in surgical techniques have improved patient outcomes but identifying which individual patients are at greatest risk of poor post-operative liver performance remains a challenge. Here we report results from a multicentre observational clinical trial (ClinicalTrials.gov NCT03213314) which aimed to inform personalised pre-operative risk assessment in liver cancer surgery by evaluating liver health using quantitative multiparametric magnetic resonance imaging (MRI). We combined estimation of future liver remnant (FLR) volume with corrected T1 (cT1) of the liver parenchyma as a representation of liver health in 143 patients prior to treatment. Patients with an elevated preoperative liver cT1, indicative of fibroinflammation, had a longer post-operative hospital stay compared to those with a cT1 within the normal range (6.5 vs 5 days; p = 0.0053). A composite score combining FLR and cT1 predicted poor liver performance in the 5 days immediately following surgery (AUROC = 0.78). Furthermore, this composite score correlated with the regenerative performance of the liver in the 3 months following resection. This study highlights the utility of quantitative MRI for identifying patients at increased risk of poor post-operative liver performance and a longer stay in hospital. This approach has the potential to inform the assessment of individualised patient risk as part of the clinical decision-making process for liver cancer surgery.

Comparative effect of desflurane and sevoflurane on liver function tests of patients with impaired hepatic function undergoing cholecystectomy: A randomized clinical study. Indian J Anaesth 2020; 64:383-390. [PMID: 32724246 PMCID: PMC7286405 DOI: 10.4103/ija.ija_168_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 03/21/2020] [Accepted: 04/08/2020] [Indexed: 11/10/2022] Open
Abstract
Background and Aim: Desflurane and sevoflurane are the most common volatile anesthetics used during laparoscopic and hepatic surgery. The objective of the study was to evaluate the effect of desflurane and sevoflurane in patients with elevated preoperative liver functions undergoing laparoscopic cholecystectomy. Methods: The study was a randomized study and included 162 patients classified randomly into two groups: Desflurane group: The patients received desflurane (end-tidal concentration 4%–6%) as an inhalational agent during the whole procedure. Sevoflurane group: The patients received sevoflurane (end-tidal concentration 2%–4%) as an inhalational agent during the whole procedure. The investigations included serum level of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), and total bilirubin. The values were serially collected at the following timepoints; T0:at the preoperative period, T1:directly after surgery, T2:1st postoperative day, T3:2nd postoperative day, T4:3rd postoperative day, T5:5th postoperative day, T6:7th postoperative day, and T7:10th postoperative day. The statistics were described in terms of mean ± standard deviation, frequencies, and percentages. Results: The preoperative liver enzymes and total bilirubin were higher than the normal range in patients of the two groups. Postoperatively, there was a decrease in the AST and ALT with desflurane more than sevoflurane from T1 to T6(P < 0.05). The ALP, GGT, and bilirubin decreased in patients of the two groups, but the comparison was insignificant (P > 0.05). Conclusion: The desflurane is a safe inhalational volatile for maintenance of anesthesia in patients with impaired liver function undergoing laparoscopic cholecystectomy. It was associated with a decrease in the liver enzymes more than the sevoflurane.

Abstract
Although still debated, post-operative modification of hemostasis seems to be less pronounced after laparoscopy compared to open surgery. Antiphospholipid antibodies might play a role in the post-operative thromboembolic risk, although their evaluation in surgical patients has never been performed. Post-operative modification of antiphospholipid antibodies could be related to the surgical approach (laparoscopic or open). In this prospective study, the authors statistically compared the pre-operative values and post-operative modification of antiphospholipid antibodies in two homogeneous groups of patients operated on by laparoscopic and open surgery. No statistical differences within each group and between the two groups were shown comparing mean values of pre-operative and post-operative antiphospholipid antibodies. In the open group, there was a significant difference between pre-operative and post-operative LAC means (P < 0.01). In the laparoscopic group, on the contrary, no significant change in LAC values between pre- and post-operative tests (P = 0.55) was observed. Since LAC could be related to coagulation disorders, this study seems to support that laparoscopic surgery might induce a less risk of post-operative thromboembolic disease.

Abstract
Aim: In this study, we investigated and compared the effect of different types of dissector (Maryland vs Hook) on changes in liver function tests (LFTs) after laparoscopic cholecystectomy. Patients & methods: The enrolled patients were divided into two groups. Group A patients underwent dissection by Maryland dissecting forceps, group B by Hook dissecting instrument. LFTs were measured preoperatively and at 1 day and 1 week, postoperatively. Results: For both Maryland and Hook dissection, the 1-day postoperative values for total bilirubin, alanine aminotransferase and aspartate aminotransferase were significantly higher than the preoperative values. Also, there were no statistical differences between Hook and Maryland. Conclusion: The elevation of LFTs seems to be attributed to other factors. Laparoscopic cholecystectomy (LC) is an alternative to laparotomy and has become the standard treatment of benign gallbladder diseases. However, it has been noted that (following LC) the serum level of certain liver function tests (LFT) raises markedly in patients who had preoperatively normal LFT. Pneumoperitoneum is the main contributing factor. This is the first study to evaluate the effect of different dissectors on alteration of LFTs after LC. As there were no statistical differences in the variation of LFTs between the Maryland and Hook, it seems that the dissector type has no effect on the alteration of LFTs.

Abstract
AIM The present study aimed at investigating the necessity of preoperative liver function tests (LFTs) in patients with uncomplicated gallstone disease before laparoscopic cholecystectomy. BACKGROUND Significant relationship between common bile duct (CBD) stones and acute cholecystitis is reported. There are contradictory reports about the effect of CBD stones on liver function tests in patients (LFTs). METHODS In the current study, patients with symptomatic cholelithiasis who referred to hospitals during January 2015 and May 2016 were enrolled. Routine tests and ultrasonography were performed on all patients before surgery. Data were presented as means ± SD and qualitative variables as frequency (percentage) were considered. Statistical analyzes were performed with SPSS software. RESULTS A consecutive series of 270 patients (58 males and 212 females) who referred for laparoscopic cholecystectomy were enrolled in this retrospective study. Pre- operative LFTs were normal in 249 patients (85%) and abnormal LFT was detected in 41 patients (15 %). CONCLUSION This study showed that 15 % of patients with cholelithiasis without dilated CBD had impaired LFTs. Routine LFTs in preoperative evaluation of symptomatic cholelithiasis usually reveals normal findings and is not helpful in uncomplicated cholelithiasis.

Abstract
BACKGROUND Retracting the lateral liver segment during laparoscopic distal gastrectomy is important for achieving an optimal surgical field. However, excessive force may injure the liver, causing temporary abnormalities of liver function tests after laparoscopic surgery. We developed a new liver retraction method and assessed its safety and utility. PATIENTS AND METHODS We retrospectively analyzed records in our surgical database of consecutive surgical patients who underwent laparoscopic distal gastrectomy for early gastric cancer. We divided the 229 patients into two groups based on the liver retraction method used, either flexible liver retraction with clipping and suturing (FLICS) or the Nathanson retractor (NR). One-to-one propensity score matching was performed to match patients, resulting in the records of 53 pairs of cases extracted from the database. Operative and postoperative outcomes were assessed, including following the values of serum liver enzymes, total bilirubin, and C-reactive protein until postoperative day 30. RESULTS There were no significant differences in patient characteristics or preoperative data in the two groups. The retraction method was not changed intraoperatively for any patients. The operative time was significantly shorter in the FLICS group, but the amount of bleeding did not differ. Liver injury was not observed as a result of liver retraction during surgery. In both groups, serum liver enzymes temporarily increased after surgery but improved rapidly thereafter. The postoperative increases in aspartate transaminase, alanine transaminase, and C-reactive protein levels were significantly lower in the FLICS than in the NR group. No serious complications associated with liver retraction were observed in either group. CONCLUSIONS Our new liver retraction technique provided an optimal surgical field without inducing liver dysfunction. It is a simple, safe, and effective liver retraction technique.

Abstract
OBJECTIVE The aim of this study was to evaluate the mid-term results of laparoscopic Kasai portoenterostomy (LKPE) for biliary atresia (BA) at our hospital. METHODS From May 2009 to May 2012, the charts of infants with BA who underwent LKPE were reviewed retrospectively. The clearance of jaundice (CJ) as well as 3-year, and 5-year survival with native liver (SNL) rates were analyzed and compared with those after open Kasai portoenterostomy (OKPE). RESULTS Forty-nine patients with BA who underwent LKPE were assigned to group A, and 40 patients with BA who underwent OKPE were assigned to group B. All patients in both groups had type III non-syndromic BA, and the LKPE and OKPE procedures were performed by 2 different surgical teams at our hospital. After median follow-up periods of 77 months in group A and 79 months in group B, the CJ and 3- and 5-year SNL rates were 61.2%, 55.1%, and 36.7% in group A, and 45.0%, 37.5%, and 25.0% in group B, respectively. The difference of CJ between group A and group B was not significant. The Kaplan-Meier method analysis showed that the difference in SNL between group A and group B was not significant either. CONCLUSIONS LKPE for patients with BA was a technically feasible and alternative procedure to OKPE. The 3- and 5-year SNL rates after LKPE were not different compared to those after OKPE.

Abstract
The aim of the current study was to identify the protective effect of hydrogen gas against liver injury during CO2 pneumoperitoneum. Rats were randomly divided into three groups: control group (C group), pneumoperitoneum group (P15 group) and hydrogen group (H2 group). Rats in the C group were subjected to anesthesia for 90 min. Rats in the P15 group received an abdominal insufflation of CO2 for 90 min at an intra-abdominal pressure of 15 mmHg. Rats in the H2 group received a hypodermic injection of hydrogen gas (0.2 mL/kg) and after 10 min they received an abdominal insufflation of CO2 for 90 min at an intra-abdominal pressure of 15 mmHg. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured to evaluate liver function. Malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione (GSH) content were measured to evaluate oxidative stress. Nuclear factor E2-related factor 2 (Nrf2) and Nrf2 downstream target genes, apoptosis-related genes and inflammatory cytokine mRNA and protein expression were detected. Liver injury was detected under the microscope. Our results revealed that liver function, antioxidants content, inflammation and liver injury were improved after hydrogen preconditioning in H2 group compared with P15 group. Overall, our results revealed that subcutaneous hydrogen injection could exert a protective effect against liver injury during CO2 pneumoperitoneum through reducing oxidative stress, cell apoptosis and inflammatory cytokines release.

Abstract
AIM To evaluate the value of blood testing after elective laparoscopic cholecystectomy and its association with procedure related complications.
METHODS Charts of all patients undergoing elective laparoscopic cholecystectomy from January 2013 through December 2014 were reviewed retrospectively for demographics, indication for surgery, operative course and outcome. In our institution the decision to perform postoperative blood analysis is left for the discretion of the surgeon, therefore we had the possibility to compare the results of those who had blood analyses results to those who did not. Analysis was performed to identify variables associated with the decision to perform postoperative blood tests. Subsequently a univariate and multivariate analyses was performed comparing the two cohorts. Secondary subgroup analysis was performed to identify factors associated with procedure related complications.
RESULTS Five hundred and thirty-two elective laparoscopic cholecystectomies for symptomatic gallstones were performed during the study period. Sixty-four percent of the patients (n = 340) had blood tests taken post operatively. Patients that had laboratory tests taken were older (P = 0.006, OR = 1.01), had longer surgery (P < 0.001, OR = 3.22) had more drains placed (P < 0.001, OR = 3.2) and stayed longer in the hospital (P < 0.001, OR = 1.2). A subgroup analysis of the patients who experienced complications revealed longer stay in the hospital (P < 0.001), higher body mass index (BMI) (P = 0.04, OR = 1.08), increased rates of drain placement (P = 0.006, OR = 3.1) and higher conversion rates (P = 0.01, OR = 14.6). Postoperative blood tests withdrawals were not associated with complications (P = 0.44). On Multivariate analysis BMI and drain placement were independently associated with complications.
CONCLUSION The current study indicate that routine postoperative blood tests after elective laparoscopic cholecystectomy for symptomatic gallstones does not predict complications and may have an added benefit in diagnosis and management of cases were the surgeon encountered true technical difficulty during surgery.

Abstract
OBJECTIVE Reducing adverse effects in laparoscopic cholecystectomy (LCE) is important to avoid complications. After removal, the porta hepatis and gallbladder bed of liver were treated with pulse width modulated (PWM) red LED light with parameters λ = 625 ± 5 nm, full width at half maximum 17 nm, 76 Hz, duty cycle 23%, 15-30 mW/cm2, and 0.9-1.8 J/cm2. The changes of eight blood parameters were studied: red blood cell, hemoglobin, white blood cell, erythrocyte sedimentation rate (ESR), bilirubin, aspartate transaminase (AST), alanine transaminase (ALT), and amylase. BACKGROUND DATA Other current methods of reducing undesirable effects of LCE significantly affect surgery and are not commonly used in practice. MATERIALS AND METHODS Before LCE, 263 patients were randomized into the control and test groups. Patients in the test group were treated with light radiated for 2 min during the surgery on the bed of the removed gallbladder and porta hepatis. Blood samples were taken before surgery and on the third day after surgery, studied, and compared by nonparametric statistical methods. RESULTS The test group revealed significant reduction in postsurgery gain of levels of ALT, AST, and ESR compared with the control group. CONCLUSIONS Treatment of the removed gallbladder bed and porta hepatis by red LED PWM radiation during LCE significantly reduces the adverse effects of surgery while increasing its time insignificantly and does not affect the surgical best practices deployed.

Abstract
BACKGROUND Laparoscopic cholecystectomies (LC) are generally performed in a 12 mmHg-pressured pneumoperitoneum in a slight sitting position. Considerable thromboembolism risk arises in this operation due to pneumoperitoneum, operation position and risk factors of patients. We aim to investigate the effect of pneumoperitoneum pressure on coagulation and fibrinolysis under general anesthesia. MATERIAL AND METHODS Fifty American Society of Anesthesiologist (ASA) I-III patients who underwent elective LC without thromboprophlaxis were enrolled in this prospective study. The patients were randomly divided into two groups according to the pneumoperitoneum pressure during LC: the 10 mmHg group (n = 25) and the 14 mmHg group. Prothrombin time (PT), thrombin time (TT), International Normalized Ratio (INR), activated partial thromboplastin time (aPTT) and blood levels of d-dimer and fibrinogen were measured preoperatively (pre), one hour (post1) and 24 h (post24) after the surgery. Moreover, alanine amino transferase, aspartate amino transferase and lactate dehydrogenase were measured before and after the surgery. These parameters were compared between and within the groups. RESULTS PT, TT, aPTT, INR, and D-dimer and fibrinogen levels significantly increased after the surgery in both of the groups. D-dimer level was significantly higher in 14-mmHg group at post24. CONCLUSION Both the 10-mmHg and 14-mmHg pressure of pneumoperitoneum may lead to affect coagulation tests and fibrinogen and D-dimer levels without any occurrence of deep vein thrombosis, but 14-mmHg pressure of pneumoperitoneum has a greater effect on D-dimer. However, lower pneumoperitoneum pressure may be useful for the prevention of deep vein thrombosis.

Abstract
The patient’s position during laparoscopic surgery can have a clinically relevant effect on lower limb and splanchnic circulation; this factor has not yet been investigated with respect to oxidative stress markers. In order to assess this effect, a prospective clinical trial was designed wherein 2 groups of patients were studied. In group A, 15 patients underwent upper abdominal nonhepatobiliary operations (13 modified Nissen fundoplications and 2 Taylor vagotomies) in the head-up position. In group B, 15 patients underwent lower abdominal operations (10 laparoscopic colectomies and 5 inguinal hernia repairs) in the head-down position. The pneumoperitoneum was maintained at 14 mm Hg in all cases. Plasma concentrations of thiobarbituric-acid reactive substances (TBARS), a marker of lipid peroxidation, plasma total antioxidant status (TAS), and serum uric acid concentrations were measured preoperatively, 5 minutes after deflation of the pneumoperitoneum, and 24 hours postoperatively. Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) serum activities were measured preoperatively and 24 hours postoperatively. In group A, there was a significant increase in TBARS levels (p<0.005) immediately after deflation of the pneumoperitoneum and a significant decrease in TAS and uric acid levels (p<0.005) in the first postoperative day. There was also a significant postoperative elevation in both ALT and AST activities (p<0.001). In group B, no significant increase was found in postoperative TBARS or transaminase levels. TAS and uric acid levels decreased significantly in the first postoperative day (p<0.05) and (p<0.005, respectively). In conclusion, these results show that a combination of pneumoperitoneum and the head-up position causes significant increase in lipid peroxidation, decrease in plasma TAS, and increase in transaminases. The mechanism responsible for these events could be the low-flow ischemia-reperfusion syndrome induced by the pneumoperitoneum and aggravated by the head-up position.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) requires the creation of a pneumoperitoneum via insufflations of carbon dioxide; resulting in increased partial pressure of carbon dioxide (CO2) and intraperitoneal pressure which leads to the changes in pulmonary function and hemodynamic measurements. Hypercarbia leads to visceral organ ischemia including liver and venous stasis/thromboembolism or both due to impaired flow. The present study has been undertaken to see the changes in liver function tests (LFTs) after laparoscopic/open cholecystectomy (OC), the incidences of such change, their relation to age, sex, duration of surgery and to know the clinical significances of such disturbances. AIMS AND OBJECTIVES To compare and correlate the serum level of bilirubin, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP) in patients who underwent LC to those who underwent OC. MATERIALS AND METHODS The present study was conducted in the Department of Surgery at MMIMSR, MM University, Mullana, Ambala. A total number of 200 patients diagnosed as cholelithiasis were included in the study from May 2012 to May 2014. These cases were randomly divided into two groups (A and B) consisting of 100 cases each. LC was performed in group A patients and OC was done in group B patients. Three blood samples were taken: (I) pre-operatively; (II) after 24 hours of surgery; and (III) after 72 hours of surgery for comparison of the enzyme level alterations. RESULTS In LC patients, there were rise in the levels of serum bilirubin, AST and ALT after 24 hrs of surgery from the preoperative value and then again fall was noted (near to normal value) after 72 hrs of surgery except in that of ALP. ALP levels showed slight fall after 24 hrs of surgery and then slight rise after 72 hrs which was within the normal limit. Whereas in OC patients, there were slight variations in the liver enzymes (which were within the normal range). CONCLUSIONS Transient elevation of serum bilirubin, AST and ALT occurs after LC or after OC. The alteration in the liver enzymes can be attributed to CO2 pneumoperitoneum, surgical manipulations, diathermy, patient position, and arterial injury may also other factors. These changes return to normal in 3-4 days after procedure and they have no clinical consequences in patients with normal hepatic function but they may still cause worry to the surgeon regarding the integrity of biliary tree.

Abstract
BACKGROUND This study examines the usefulness of early post-operative liver function test (LFT) monitoring in predicting retained choledocholithiasis after laparoscopic common bile duct exploration (LCBDE). METHODS Data on patients who had LCBDE over a 3-year period were collected retrospectively. Patients who had ongoing choledocholithiasis after unsuccessful LCBDE were considered for the test group and patients who had successful LCBDE were considered for the control group. Preoperative, day 1 post-operative and day 2 post-operative alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), alanine transaminase (ALT) and bilirubin levels were recorded. Proportions of patients who had worsening LFTs were analysed in each group. RESULTS Proportions of patient who had worsening LFTs on day 1 were not statistically different between two groups and they were statistically equal on equivalence testing (two one-sided tests). On day 2, proportions of patient were again not statistically different. Bilirubin and ALT were statistically equivalent (P = 0.022 and P = 0.025 respectively) but GGT and ALP failed to achieve statistical equivalence (P = 0.062 and P = 0.138 respectively) on day 2. Twelve patients with normal appearing final intraoperative cholangiogram needed reintervention due to retained choledocholithiasis diagnosed subsequently. LFTs progressively improved despite presence of choledocholithiasis in eight of these 12 patients (75%) and only four were diagnosed by worsening post-operative LFTs during index admission. CONCLUSION LFTs in the early post-operative period are not useful in determining which patients require biliary imaging or intervention after an apparently successful LCBDE.

Abstract
INTRODUCTION Postoperative abnormal liver function tests (LFT) following laparoscopic cholecystectomy (LC) could present a substantial clinical dilemma due to suspicion of missed choledocholithiasis or more serious complications such as bile duct injury. We noted that LFT were more likely to be abnormal when an intraoperative cholangiogram (IOC) had been performed. This study aims to examine if contrast injection into the biliary tract during IOC is associated with deranged LFT. METHODS Data on all LC performed in a tertiary referral hospital network over a period of 30 months were collected retrospectively, and two groups were identified depending on successful performance of an IOC. Identical inclusion and exclusion criteria were applied to both groups to identify eligible patients. Alkaline phosphatase, gamma-glutamyl transferase (GGT), alanine transaminase (ALT), and bilirubin levels were recorded, and the mean difference between preoperative and postoperative values was analyzed. RESULTS There were 177 eligible patients: 147 patients in the LC with IOC test group (IOC group) and 30 patients in the LC without IOC control group (NO IOC group). Demographics and preoperative mean LFT were not significantly different between groups. In the IOC group, the mean ALT difference (43 ± 57, P =< 0.001) and GGT difference (34 ± 66, P =< 0.001) were significantly higher than in the NO IOC group (ALT [19 ± 25], GGT [7 ± 20]). The mean alkaline phosphatase difference (IOC [9 ± 47], NO IOC [-2 ± 14], P = 0.214) and mean bilirubin difference (IOC [-2 ± 9], NO IOC [-1 ± 8], P = 0.911) were not significantly different. CONCLUSION The performance of an IOC is associated with elevated GGT and ALT but does not affect alkaline phosphatase and bilirubin concentrations.

Abstract
PURPOSE We assessed the effect of high partial pressure of arterial carbon dioxide (PaCO2) due to pneumoperitoneum (PP) on growth (height/weight) and development (gross/fine motor function, receptive/expressive communication, and social interaction), by comparing outcome after portoenterostomy (PE) for biliary atresia (BA) using laparoscopic PE (LPE: n = 13) and open PE (OPE: n = 13) cases performed between 2005 and 2014. METHODS Our PE is based on Kasai's original PE. All data were collated prospectively. RESULTS Differences in duration of follow-up (LPE: 38.8 months; OPE: 38.1 months), jaundice clearance (LPE: 12/13 = 92.3 %; OPE: 9/13 = 69.2 %), survival with the native liver (LPE: 10/13 = 76.9 %; OPE: 9/13 = 69.2 %), incidence of cholangitis, hypersplenism, and incidence of esophageal varices were not significant. Mean intraoperative PaCO2 was significantly higher in LPE (LPE: 50.1 mmHg; OPE: 40.7 mmHg, p < 0.05). Liver function impairment was not statistically different, although LPE results were slightly worse. There was no overall delay in growth observed, although height/weight gain was more consistent in LPE. The pattern of developmental delay observed was similar for LPE and OPE suggesting that developmental delay is not PE-related; in other words, PP is not implicated in developmental delay. CONCLUSIONS PP during LPE would appear to have no adverse effects on overall growth/development and liver function in BA patients.

Abstract
PURPOSE Generally, open portoenterostomy (PE) involves a wide extended anastomosis and all sutures are deep [extended PE (EP)]. In contrast, the anastomosis in Kasai's PE (KP), our modified open Kasai PE (MK), and our laparoscopic modified Kasai PE (lapMK) involve shallow suturing, especially at the 2 and 10 o'clock positions where the right and left bile ducts would be normally. We compared outcomes of 36 consecutive biliary atresia (BA) patients treated by three types of PE at a single institution during the period 2005-2014; EP (n = 13), MK (n = 11), and lapMK (n = 12). METHODS We compared age at PE, time taken to become jaundice-free (total bilirubin ≤1.2 mg/dL; JF time), proportion of JF subjects [JF ratio (JFR)], steroid dosage, incidence of cholangitis, postoperative liver function and CRP, presence of hypersplenism, requirement for liver transplantation (LTx), and JF survival with the native liver (JF+NL) as indicators of outcome. RESULTS Patient demographics, steroid dosage, JF time, incidence of cholangitis, presence of hypersplenism, operating time, blood loss and postoperative biochemistry were similar for all groups. However, JFR was significantly higher for lapMK (100 %) versus EP (46.2 %) (p < 0.05), but not for MK (81.8%) versus EP. Kaplan-Meier analysis showed survival with NL was significantly higher for lapMK (10/12: 83.3%: JF in 9; not JF in 1) and MK (9/11: 81.8 %: JF in all) versus EP (3/13: 23.1%: JF in all) (p < 0.05, respectively), but not for lapMK versus MK. JF+NL in both lapMK (9/12: 75.0%) and MK (9/11: 81.8%) were significantly higher compared with EP (3/13: 23.1%) (p < 0.05, respectively). Intraperitoneal adhesions were less pronounced at LTx in lapMK compared with MK or EP. CONCLUSIONS This study would suggest that depth of suturing during PE would appear to influence post-PE outcome. LapMK should be reconsidered as a valid treatment option for BA.

Association between duration of carbon dioxide pneumoperitoneum during laparoscopic abdominal surgery and hepatic injury: a meta-analysis. PLoS One 2014; 9:e104067. [PMID: 25110982 PMCID: PMC4128655 DOI: 10.1371/journal.pone.0104067] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2014] [Accepted: 07/06/2014] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND The aim of this study is to accurately assess whether the duration of intraoperative carbon dioxide pneumoperitoneum (CDP) is associated with the induction of hepatic injury. METHODS We conducted a systematic review of PubMed, Embase, and Cochrane Library databases (through February 2014) to identify case-match studies that compared high-pressure CDP with low-pressure CDP or varied the duration of CDP in patients who underwent abdominal surgery. The outcome of interest was postoperative liver function (ALT, AST, TB). RESULTS Eleven comparative studies involving 2,235 participants were included. Overall, levels of ALT, AST, and TB (on postoperative days 1, 3, and 7) were significantly elevated in the study groups. However, the results of the subanalyses of those who underwent laparoscopic colorectal cancer resection (LCR) versus open colorectal cancer resection (OCR) and those who underwent laparoscopic gastric bypass (LGBP) versus open gastric bypass (OGBP) were inconsistent. CONCLUSIONS The current evidence suggests that the duration of CDP during laparoscopic abdominal surgery may be associated with hepatic injury. Additional large-scale, randomized, controlled trials are urgently needed to further confirm this.

Abstract
BACKGROUND The complication rate after surgery for gastric cancer varies according to the particular definition of morbidity. Complications after gastrectomy should be reported using a standardized method. The present study retrospectively analyzed patient outcomes after open distal gastrectomy (ODG) and laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer using a standardized classification system of the severity of complications (the Clavien-Dindo system). METHODS A total of 1,631 patients who underwent curative ODG or LADG for gastric adenocarcinoma between May 2003 and December 2009 were included in the study and any risk factors related to complications were analyzed. RESULTS Six hundred twenty-nine patients were treated with ODG and 1,002 with LADG. Postoperative complications were less frequent in the LADG group than in the ODG group (25.3% vs. 40.1%, P < 0.001), and fewer major complications (Clavien-Dindo classification ≥IIIa) were observed with LADG than with ODG (2.1% vs. 5.4%, P < 0.001). Multivariate analysis showed that the laparoscopic surgical approach correlated with significantly fewer overall and major complications in patients with stage I disease. CONCLUSION Using the Clavien-Dindo system, we observed fewer complications with LADG than with ODG. This shows that the laparoscopic approach for treating gastric cancer is less invasive than the open approach in terms of morbidity. Future studies will be needed to confirm this.

Abstract
This study suggests that mild to moderate elevation in preoperative liver function tests may not be associated with deleterious effects, and in the absence of clinical indications, routine preoperative or postoperative liver function testing may not be necessary. Background and Objectives: Liver function tests (LFTs) include alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transpeptidase (GGT), alkaline phosphatase (ALP), and bilirubin. The role of routine testing before and after laparoscopic cholecystectomy was evaluated in this study. Patients and Methods: A total of 355 patients were retrospectively analyzed by examining the LFTs the day before, the day after, and 3 weeks after the surgery. The Wilcoxon signed-rank test and Student t test were performed to determine statistical significance. Results: Alterations in the serum AST, ALT, and GGT were seen on the first postoperative day. Minor changes were seen in bilirubin and ALP. An overall disturbance in the LFTs was seen in more than two-thirds of the cases. Repeat LFTs performed after 3 weeks on follow-up were found to be within normal limits. Conclusion: Mild-to-moderate elevation in preoperative LFTs may not be associated with any deleterious effect, and, in the absence of clinical indications, routine preoperative or postoperative liver function testing is unnecessary.

Abstract
AIM: To observe the hepatic injury induced by carbon dioxide pneumoperitoneum (CDP) in rabbits, compare the effects of low- and high-pressure pneumoperitoneum, and to determine the degree of hepatic injury induced by these two clinically relevant CDP pressures.
METHODS: Thirty healthy male New Zealand rabbits weighing 3.0 to 3.5 kg were randomly divided into three groups (n = 10 for each group) and subjected to the following to CDP pressures: no gas control, 10 mmHg, or 15 mmHg. Histological changes in liver tissues were observed with hematoxylin and eosin staining and transmission electron microscopy. Liver function was evaluated using an automatic biochemical analyzer. Adenine nucleotide translocator (ANT) activity in liver tissue was detected with the atractyloside-inhibitor stop technique. Bax and Bcl-2 expression levels were detected by western blotting.
RESULTS: Liver functions in the 10 mmHg and 15 mmHg experimental groups were significantly disturbed compared with the control group. After CDP, the levels of alanine transaminase and aspartate transaminase were 77.3 ± 14.5 IU/L and 60.1 ± 11.4 IU/L, respectively, in the 10 mmHg experimental group and 165.1 ± 19.4 IU/L and 103.8 ± 12.3 IU/L, respectively, in the 15 mmHg experimental group, which were all higher than those of the control group (P < 0.05). There was no difference in pre-albumin concentration between the 10 mmHg experimental group and the control group, but the pre-albumin level of the 15 mmHg experimental group was significantly lower than that of the control group (P < 0.05). No significant differences were observed in the levels of total bilirubin or albumin among the three groups. After 30 and 60 min of CDP, pH was reduced (P < 0.05) and PaCO2 was elevated (P < 0.05) in the 10 mmHg group compared with controls, and these changes were more pronounced in the 15 mmHg group. Hematoxylin and eosin staining showed no significant change in liver morphology, except for mild hyperemia in the two experimental groups. Transmission electron microscopy showed mild mitochondrial swelling in hepatocytes of the 10 mmHg group, and this was more pronounced in the 15 mmHg group. No significant difference in ANT levels was found between the control and 10 mmHg groups. However, ANT concentration was significantly lower in the 15 mmHg group compared with the control group. The expression of hepatic Bax was significantly increased in the two experimental groups compared with the controls, but there were no differences in Bcl-2 levels among the three groups. Twelve hours after CDP induction, the expression of hepatic Bax was more significant in the 15 mmHg group than in the 10 mmHg group.
CONCLUSION: A CDP pressure of 15 mmHg caused more substantial hepatic injury, such as increased levels of acidosis, mitochondrial damage, and apoptosis; therefore, 10 mmHg CDP is preferable for laparoscopic operations.

Abstract
BACKGROUND Retraction of the liver is necessary to ensure an adequate working space in laparoscopic surgery, but the retraction force applied may cause transient liver dysfunction. We have introduced the technique using a Penrose drain to suspend the liver with the performance of laparoscopic gastrectomy for gastric adenocarcinoma. METHODS 111 patients with gastric adenocarcinoma underwent laparoscopic gastrectomy using either a Penrose drain (n = 47) or a Nathanson's retractor (n = 64) for displacement of the liver. Serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, alkaline phosphatase (ALP) and albumin were compared among the groups at baseline, immediately after operation, and on postoperative days (POD) 1, 2, 3, 5, and 7. RESULTS The levels of ALT on POD 2, 3, and 5 were significant higher in the Nathanson's retractor group than in the Penrose drain group. Levels of AST on POD 2 and 3 were also higher in the Nathanson's retractor group than in the Penrose drain group. There was no significant difference in total bilirubin, ALP, and serum albumin levels between groups. CONCLUSIONS The use of the Penrose drain for retraction of the liver appears to attenuate postoperative liver dysfunction during laparoscopic gastrectomy for gastric adenocarcinoma.

Abstract
AIM: To evaluate the factors associated with liver function alterations after laparoscopy-assisted gastrectomy (LAG) for gastric cancer.
METHODS: We collected the data of gastrectomy patients with gastric cancer and divided them into 2 groups: open gastrectomy (OG) and LAG. We also collected the data of patients with colon cancer to evaluate the effect of liver manipulations during surgery on liver function alterations. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, and alkaline phosphatase were measured on the preoperative day and postoperative day 1 (POD1), POD3, POD5, and POD7.
RESULTS: No changes in liver function were observed after the operation in patients with colon cancer (n = 121). However, in gastric cancer patients (n = 215), AST and ALT levels increased until POD5 compared to those in colon cancer patients and these findings were observed both in the LAG and OG without a significant difference except at POD1. The mean hepatic enzyme levels at POD1 in the LAG group were significantly higher than those in the OG group (P = 0.047 for AST and P = 0.039 for ALT). The factors associated with elevated ALT on POD1 in patients with gastric cancer were body mass index (P < 0.001), operation time (P < 0.001), intraoperative hepatic injury (P = 0.048), and ligation of an aberrant left hepatic artery (P = 0.052) but not type of operation (OG vs LAG, P = 0.094).
CONCLUSION: We conclude that the liver function alteration after LAG may have been caused by direct liver manipulation or aberrant hepatic artery ligation rather than the CO2 pneumoperitoneum.

Abstract
HYPOTHESIS We hypothesized that livers with biliary atresia (BA) are more susceptible to the harmful effects of a high-pressure CO(2) pneumoperitoneum (PP) than healthy livers. METHODS A murine model of BA was used in this experiment. Mice were divided into 6 groups: (1) control Balb/c; (2) control Balb/c, CO(2)-PP; (3) control BA; (4) BA-sham; (5) BA, CO(2)-PP; and (6) BA, air-PP. Mice from groups 2, 5, and 6 underwent an 8-mm Hg-PP for 60 minutes. Liver samples were collected for histology, colorimetry, and flow cytometry analysis 18 to 24 hours after the procedure. Markers of apoptosis were investigated as indicators of acute cell damage. RESULTS We observed a statistically significant higher rate of apoptosis in livers with BA exposed to a prolonged CO(2)-PP or air-PP compared with control groups. There were no significant differences between groups 1 and 2, or between groups 5 and 6. CONCLUSIONS In this animal model, we have shown that livers with BA are more susceptible than healthy livers to injury by a prolonged PP. This injury was caused by both CO(2) and air-PP, implying that it is the direct result of pressure. These results may have implications for the success of minimally invasive Kasai procedures.

Abstract
In the last few years, the use of laparoscopy in veterinary medicine has expanded and consequently so was the need for studies that establish the advantages, disadvantages and possible complications of each procedure. The purpose of the current study was to describe a laparoscopic splenectomy technique and the alterations due to this access, and compare it to the open procedure in dogs. A total of 15 healthy female mongrel dogs were used, with mean weight of 17.4±2.5kg. The animals were distributed into three groups: Group IA of open splenectomy (laparotomy) using double ligation of the vessels of the splenic hilum with poliglicolic acid, Group IB of open splenectomy (laparotomy) with bipolar electrocoagulation of the splenic hilum, and Group II of laparoscopic access with bipolar electrocoagulation of the splenic hilum. Operative time, blood loss, size of incisions, complications during and after surgery were evaluated. Other parameters included pain scores, white blood cell (WBC) counts and postoperative serum concentrations of alanine aminotransferase (ALT), alkaline phosphatase (ALP), creatine kinase (CK), C-reactive protein (CRP), glucose and cortisol. No differences were found in the evaluation of parameters between both open splenectomy techniques employed. Laparoscopic access presented significant differences (p<0,05) when compared with open surgery: Longer operative time, smaller abdominal access, decrease in blood loss, lower concentrations of CRP, higher levels of CK and ALP, and lower scores in the pain scale. Laparoscopic surgery showed fewer complications of the surgical wound. No significant differences were observed between groups in the postoperative temperature, WBC, ALT, cortisol and glucose concentrations. In conclusion, the laparoscopic technique is useful for splenectomy in dogs, being advantageous in terms of blood loss, surgical stress and surgical wounds. However, it expends more operative time and causes transitory increase in hepatic and muscular enzymes.

Abstract
AIM: To observe the hepatic injury induced by carbon dioxide pneumoperitoneum in rats and to explore its potential mechanism.
METHODS: Thirty healthy male SD rats were randomly divided into control group (n = 10), 0 h experimental group (n = 10) and 1 h experimental group (n = 10) after sham operation with carbon dioxide pneumoperitoneum. Histological changes in liver tissue were observed with hematoxylin-eosin staining. Liver function was assayed with an automatic biochemical analyzer. Concentration of malonyldialdehyde (MDA) and activity of superoxide dismutase (SOD) were assayed by colorimetry. Activity of adenine nucleotide translocator in liver tissue was detected with the atractyloside-inhibitor stop technique. Expression of hypoxia inducible factor-1 (HIF-1) mRNA in liver tissue was detected with in situ hybridization.
RESULTS: Carbon dioxide pneumoperitoneum for 60 min could induce liver injury in rats. Alanine aminotransferase and aspartate aminotransferase were 95.7 ± 7.8 U/L and 86.8 ± 6.9 U/L in 0 h experimental group, and 101.4 ± 9.3 U/L and 106.6 ± 8.7 U/L in 1 h experimental group. However, no significant difference was found in total billirubin, albumin, and pre-albumin in the three groups. In 0 h experimental group, the concentration of MDA was 9.83 ± 2.53 &mgr;mol/g in liver homogenate and 7.64 ± 2.19 &mgr;mol/g in serum respectively, the activity of SOD was 67.58 ± 9.75 nu/mg in liver and 64.47 ± 10.23 nu/mg in serum respectively. In 1 h experimental group, the concentration of MDA was 16.57 ± 3.45 &mgr;mol/g in liver tissue and 12.49 ± 4.21 &mgr;mol/g in serum respectively, the activity of SOD was 54.29 ± 7.96 nu/mg in liver tissue and 56.31 ± 9.85 nu/mg in serum, respectively. The activity of ANT in liver tissue was 9.52 ± 1.56 in control group, 6.37 ± 1.33 in 0 h experimental group and 7.28 ± 1.45 (10-9 mol/min per gram protein) in 1 h experimental group, respectively. The expression of HIF-1 mRNA in liver tissue was not detected in control group, and its optical density difference value was 6.14 ± 1.03 in 0 h experimental group and 9.51 ± 1.74 in 1 h experimental group, respectively.
CONCLUSION: Carbon dioxide pneumoperitoneum during the sham operation can induce hepatic injury in rats. The probable mechanisms of liver injury include anoxia, ischemia reperfusion and oxidative stress. Liver injury should be avoided during clinical laparoscopic operation with carbon dioxide pneumoperitoneum.

The impact of carbon dioxide pneumoperitoneum on liver regeneration after liver resection in a rat model. Surg Endosc 2009; 24:1-8. [PMID: 19533243 DOI: 10.1007/s00464-009-0536-x] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2009] [Revised: 04/03/2009] [Accepted: 05/01/2009] [Indexed: 12/12/2022]
Abstract
BACKGROUND In recent years, laparoscopic hepatic resection is performed by an increasing number of surgeons. Despite many advantages of the laparoscopic procedure, it is unclear whether the pneumoperitoneum affects the postoperative liver regeneration after liver resection. The current study aimed to investigate the influence of a carbon dioxide (CO(2)) pneumoperitoneum on liver regeneration in a rat model. METHODS In this study, 60 male Wistar rats were subjected to 70% partial hepatic resection. Of these 60 animals, 30 underwent preoperative pneumoperitoneum at 9 mmHg for 60 min. After hepatic resection, the rats were killed at 12, 24, and 48 h, and on days 4 and 7. The outcome parameters were hepatocellular injury (plasma aminotransferases), oxidative stress (plasma malondialdehyde), interleukin-6 (IL-6), and liver regeneration (mitotic index, KI-67; regenerating liver mass). RESULTS The mitotic index was significantly lower in the pneumoperitoneum group than in the group without pneumoperitoneum at all time points (p < 0.05). In the pneumoperitoneum group, KI-67 was significantly lower on day 4 (p < 0.05). The liver regeneration rate was significantly lower for the animals with pneumoperitoneum on days 2 and 4 (p < 0.05). The postoperative hepatocellular injury was significantly greater after pneumoperitoneum at 12, 24, and 48 h (p < 0.05). Plasma malondialdehyde and IL-6 were significantly higher in the pneumoperitoneum group at 24 h and on day 4 (p < 0.05). CONCLUSION This study showed that pneumoperitoneum before extended liver resection impaired postoperative liver regeneration. Oxidative stress reaction and hepatocellular damage was markedly higher after pneumoperitoneum. Further investigations, especially with patients that have impaired liver function, are necessary for clinical consequences to be drawn from these results.

Abstract
BACKGROUND Transient transaminitis has been identified following laparoscopic abdominal surgery. However, the importance of posture, duration of surgery, and mechanical retraction in its etiology remain unclear. METHODS Liver function was assessed preoperatively then at 8, 24, 48 and 72 h following laparoscopic surgery including the following procedures: Nissen fundoplication (LN: n = 10); cholecystectomy (LC: n = 10); inguinal herniorrhaphy (LH: n = 10); and gastrectomy (LG: n = 5). RESULTS Aspartate aminotransferase (AST) levels in LN patients exhibited a rapid rise within 8 h, peaking at 48 h before returning toward baseline. In the LN group, AST levels were significantly higher at 8 h and 24 hours compared to all other groups and compared to LG at 48 h and 72 h. At 6-week follow-up all AST levels were normal. No significant differences were seen in other hepatic parameters, and no correlation between AST and duration of operation, gender, or age was identified. CONCLUSIONS Antireflux surgery is associated with transaminitis related to hepatic retraction, which is independent of patient posture or duration of observation, and it resolves spontaneously with no clinical consequences.

Abstract
BACKGROUND Subclinical hepatic dysfunction after laparoscopic cholecystectomy (LC) has been described in the literature. However, this alteration is not encountered in all patients. In order to address this situation, a prospective study was conducted to investigate the effect of abdominal perfusion pressure (APP) on liver function tests after LC performed under constant intra-abdominal pressure (IAP). PATIENTS AND METHODS Of 78 patients who underwent LC between May 2007 and October 2007, 40 patients were eligible for the study. In all the patients, six parameters of liver function (aspartate aminotransferase, alanine aminotransferase, direct bilirubin, indirect bilirubin, alkaline phosphatase, and gamma-glutamyltransferase) were assessed before and 24 hours after surgery. Patients who showed more than a 100% increase in at least one parameter (group 1) were compared to those who did not (group 2) regarding age, sex, body weight, body height, operation time, pneumoperitoneum time, IAP, preoperative, and intraoperative APP. RESULTS Of the patients, 37.5% showed more than a 100% increase in at least one parameter of liver function. No significant difference was found between the two groups with regard to age, sex, body weight, body height, operation time, pneumoperitoneum time, and IAP. There were significant increase in AST and ALT at 24 hours postoperatively in group 1, as compared with group 2 (P = 0.000, P = 0.001). In comparison of preoperative APP with intraoperative APP values, group 1 showed a statistically significant decrease (P = 0.000), while no difference was found in group 2. CONCLUSION Subclinical hepatic dysfunction after LC could mostly be attributed to the negative effects of the pneumoperitoneum on hepatic blood flow. For the evaluation of hepatic hypoperfusion, APP may be a new criterion as a determinant of interaction with mean arterial pressure (MAP) and IAP.

Abstract
OBJECTIVES To compare routine radiologic and laboratory findings after extraperitoneal and transperitoneal laparoscopic radical prostatectomy (eLRP, tLRP) and assess relevant clinical correlations. METHODS Fifty consecutive eLRP and tLRP (laparoscopic and robot-assisted) were evaluated. Preoperative complete metabolic panel and complete blood count were determined, and these serum tests and amylase and lipase level measurements were repeated postoperatively. Ten consecutive eLRP and tLRP patients also underwent flat and upright abdominal x-rays. Operative time, perioperative complications, length of hospital stay, and amount of narcotic used were measured for each group. RESULTS On postoperative day 1, all eLRP patients evaluated (100%) had radiographic free air in the abdomen, as did 80% of the tLRP patients. Only 1 of 50 patients (2%) had elevated aspartate aminotransferase (eLRP), 2 of 50 (4%) had elevated alanine aminotransferase (both eLRP), and 4 of 50 (8%) had elevated amylase (3 eLRP, 1 tLRP). Postoperative narcotic usage (eLRP 25 +/- 3 mg versus tLRP 23 +/- 5 mg morphine equivalents) and operative times (eLRP 3.6 +/- 0.1 hours versus tLRP 3.8 +/- 0.1 hours) were similar between the groups. Length of hospital stay was lower in the eLRP compared with the tLRP group (1.9 +/- 0.1 days versus 2.2 +/- 0.1 days, P <0.05). Perioperative complications did not differ significantly between groups. CONCLUSIONS Extraperitoneal LRP and tLRP patients had comparable perioperative outcomes, and few had abnormal serum metabolic laboratory values postoperatively. Unexpectedly, abdominal free air was found in all eLRP patients evaluated radiographically on postoperative day 1, a finding that should be interpreted as normal and not specific for bowel injury in this context.

Abstract
BACKGROUND Carbon dioxide (CO(2)) pneumoperitoneum induces peritoneal oxidative stress. This experimental, randomized, controlled study was designed to investigate the effect of pentoxifylline on oxidative stress induced by CO(2 )pneumoperitoneum. METHODS For this study, 36 Swiss albino rats were randomized into three groups. Arteria, vena femoralis, and peritoneal cavity were cannulated after anesthesia. The arterial pH, partial arterial oxygen pressure (PaO(2)), venous PO(2), arterial and venous PO(2) difference (P((a-v))O(2)), serum aspartate aminotransferase (AST), serum alanine aminotransferase (ALT), and thiobarbituric acid-reactive substances (TBARS) were studied at the end of the first and second hours in group 1 (control). In group 2, 1 cc isotonic NaCl was injected into peritoneal cavity and then CO(2) pneumoperitoneum was established. At the end of the first hour of insufflation and one hour after desufflation, the same parameters as in group 1 were studied. In group 3, the CO(2) pneumoperitoneum plus pentoxifylline group, all procedures as in group 2 were repeated, with the exception of pentoxifylline (50 mg/kg) injected in place of saline. RESULTS At the end of the first hour, P((a-v))O(2 )value in group 2 was significantly less than in the control group (group 1) and group 3 (p \ 0.05). There were no significant differences in PaO(2, )pH, AST, and ALT values between groups (p [ 0.05). TBARS level in group 1 was significantly lower than in the other groups, but there was no significant difference in TBARS level between groups 2 and 3. At the end of the second hour, TBARS level in group 3 was significantly lower than in group 2 (p \ 0.05). CONCLUSIONS Pentoxifylline may reduce the oxidative injury following laparoscopic procedures.

Abstract
BACKGROUND This study aimed to investigate the time course changes in liver histology during carbon dioxide (CO(2)) pneumoperitoneum in a large animal model. METHODS For this study, 14 white pigs were anesthetized. Liver biopsies performed 0, 1, and 2 h after establishment of CO(2) pneumoperitoneum (at 12 mmHg) and after peritoneal desufflation were sent for histologic examination. Heart rate, mean blood pressure, hepatic artery flow, portal vein flow, and aortic flow were recorded in 10-min increments. Three animals served as control subjects. RESULTS A statistically significant time course increase was observed in portal inflammation, intralobular inflammation, edema, sinusoidal dilation, sinusoidal hyperemia, centrilobular dilation, centrilobular hyperemia, pericentrilobular ischemia, and focal lytic necrosis scores. There were no significant changes in the control group. This eliminated an effect of anesthesia only. The portal vein flow increased as much as 21%, and the hepatic artery flow decreased as much as 31% of baseline, but these differences did not attain statistical significance. Aortic flow remained relatively stable. CONCLUSION Histomorphologic changes occurred, indicating liver tissue injury during CO(2) pneumoperitoneum at an intraabdominal pressure of 12 mmHg in the porcine model. Portal vein flow increased, and hepatic artery flow decreased, whereas aortic flow remained relatively unaffected in this experiment.

Abstract
BACKGROUND It has been noted that following a laparoscopic cholecystectomy (LC), liver function parameters were disturbed. The causes of this disturbance are still controversial. PATIENTS AND METHODS The serum levels of eight parameters of liver function were measured both before and 24 hours after surgery in 142 consecutive patients who underwent LC, 23 patients who underwent open cholecystectomy (OC), and in 25 patients who underwent a conventional hernial repair. The same anesthetic protocol was applied to all patients in the various groups and in the case of LC; the intra-abdominal pressure was maintained at 12 mmHg of CO2. RESULTS Twenty-four (24) hours after surgery, there was a statistically significant change of all the eight parameters studied, except alkaline phosphatase in patients who underwent LC, whereas there were only 3 patients from the OC group who had changes of alanine aminotransferase and aspartite aminotransferase and 2 patients who had raised levels of direct bilirubin, and no changes were observed among those who had conventional hernial repair. We found that 83% of the patients showed more than a 100% increase in at least one parameter, 43% showed an increase in two or more parameters, and 23% showed an increase in three or more parameters. We also observed a significant drop of total proteins and albumin levels in all patients who had LC. CONCLUSIONS It appears that the pneumoperitoneum plays a major role in these changes. Although these changes of liver function were of no clinical relevance in healthy patients, the safety of the procedure must nonetheless be assessed in those with underlying liver diseases.

Abstract
BACKGROUND During laparoscopic surgery, pneumoperitoneum is generally established by means of carbon dioxide (CO(2)) insufflation which may disturb hepatic microperfusion. It has been suggested that the desufflation at the end of the procedure creates a model of reperfusion in a previously ischemic liver, thus predisposing it to reperfusion injury. METHODS To study the effects of pneumoperitoneum on hepatic microcirculation, Sprague-Dawley rats underwent pneumoperitoneum with an intraabdominal pressure of 8 or 12 mmHg for 90 min. Subsequently, in vivo microscopy was performed to assess intrahepatic microcirculation and transaminases were measured to index liver injury. RESULTS A CO(2) pneumoperitoneum of 8 mmHg did not change serum transaminases; however, further increase of intraperitoneal pressure to 12 mmHg significantly increased AST, ALT, and LDH measured after desufflation to almost 1.5 times as much as control values of 49 +/- 5 U/L, 31 +/- 3 U/L, and 114 +/- 12 U/L. In parallel, in all subacinar zones the permanent adherence of both leukocytes and platelets to the endothelium increased by about sixfold and threefold, respectively. Furthermore, Kupffer cells labeled with latex beads as an index for their activation were significantly increased compared to controls. CONCLUSION This in vivo observation demonstrated traces of reperfusion injury in liver induced by the insufflation and desufflation of CO(2 )pneumoperitoneum. The clinical relevance of this finding and the issue of using hepatoprotective substances to prevent this injury should be further investigated.
