Cirrhosis is not a contraindication to laparoscopic surgery

Colectomy in patients with liver disease: albumin-bilirubin score accurately predicts outcomes

BACKGROUND

Patients with liver disease undergoing colectomy have higher rates of complications and mortality. The Albumin-Bilirubin score is a recently developed system, established to predict outcomes after hepatectomy, that accounts for liver dysfunction.

METHODS

All patients undergoing colectomy were identified in the 2015-2018 American College of Surgeons National Surgical Quality Improvement Program colectomy-targeted database. Demographics and outcomes were compared between patients with Albumin-Bilirubin Grade 1 vs. 2/3. Multivariable regression was performed for outcomes including colorectal-specific complications. Areas under the receiver operative characteristic curves were calculated to determine accuracy of the Albumin-Bilirubin score.

RESULTS

Of 86,273 patients identified, 48% (N = 41,624) were Albumin-Bilirubin Grade 1, 45% (N = 38,370) Grade 2 and 7% (N = 6,279) Grade 3. Patents with Grade 2/3 compared to Grade 1 had significantly increased mortality (7.2% vs. 0.9%, p < 0.001) and serious morbidity (31% vs. 12%, p < 0.001). Colorectal-specific complications including anastomotic leak (3.7% vs. 2.8%, p < 0.001) and prolonged ileus (26% vs. 14%, p < 0.001) were higher in patients with Grade 2/3. Grade 2/3 had increased risk of mortality (odds ratio 3.07, p < 0.001) and serious morbidity (1.78, p < 0.001). Albumin-Bilirubin had excellent accuracy in predicting mortality (area under the curve 0.81, p < 0.001) and serious morbidity (0.70, p < 0.001).

CONCLUSION

Albumin-Bilirubin is easily calculated using only serum albumin and total bilirubin values. Grade 2/3 is associated with increased rates of mortality and morbidity following colectomy. Albumin-Bilirubin can be applied to risk-stratify patients prior to colectomy.

Should we be reluctant to perform pancreatectomy in patients with chronic liver disease? A single center 10-year experience

PURPOSE

Many studies have shown extra-hepatic surgery in patients with chronic liver disease (CLD) with or without portal hypertension can result in complications. The aim of this study was to analyze the results of major pancreatectomy in patients with CLD including cirrhosis and to evaluate their efficacy and safety.

METHODS

We retrospectively reviewed 319 patients undergoing open pancreatoduodenectomy (PD) or distal pancreatectomy (DP) in our center. Those who received PD and DP in patients without CLD were classified into groups A and D, and those with CLD into groups B and C, respectively. Group B and C were subdivided into groups 1 and 2 according to the presence of portal hypertension.

RESULTS

Forty-three patients (13.5%) had CLD. Of the 221 patients who received PD, 25 had CLD. Of the 98 patients who received DP, 18 (Group C) had CLD. In the PD group, patients with portal hypertension (group B1) had longer operative time. However, the transfusion rate and complication rate were not significantly different from other groups. There was no mortality in patients with CLD without portal hypertension (group B2) and the complication and mortality rate was comparable to patients with normal liver function (group A). In the DP group, the transfusion rate, complication rate and mortality rate were significantly higher in patients with portal hypertension (group C1).

CONCLUSIONS

Acceptable outcomes were obtainable following pancreatic surgery in cirrhotic, non-portal hypertensive patients with surgical outcomes equivalent to non-cirrhotic patients.

Guidance document: risk assessment of patients with cirrhosis prior to elective non-hepatic surgery

As a result of the increasing incidence of cirrhosis in the UK, more patients with chronic liver disease are being considered for elective non-hepatic surgery. A historical reluctance to offer surgery to such patients stems from general perceptions of poor postoperative outcomes. While this is true for those with decompensated cirrhosis, selected patients with compensated early-stage cirrhosis can have good outcomes after careful risk assessment. Well-recognised risks include those of general anaesthesia, bleeding, infections, impaired wound healing, acute kidney injury and cardiovascular compromise. Intra-abdominal or cardiothoracic surgery are particularly high-risk interventions. Clinical assessment supplemented by blood tests, imaging, liver stiffness measurement, endoscopy and assessment of portal pressure (derived from the hepatic venous pressure gradient) can facilitate risk stratification. Traditional prognostic scoring systems including the Child-Turcotte-Pugh and Model for End-stage Liver Disease are helpful but may overestimate surgical risk. Specific prognostic scores like Mayo Risk Score, VOCAL-Penn and ADOPT-LC can add precision to risk assessment. Measures to mitigate risk include careful management of varices, nutritional optimisation and where possible addressing any ongoing aetiological drivers such as alcohol consumption. The role of portal decompression such as transjugular intrahepatic portosystemic shunting can be considered in selected high-risk patients, but further prospective study of this approach is required. It is of paramount importance that patients are discussed in a multidisciplinary forum, and that patients are carefully counselled about potential risks and benefits.

Muscle-Invasive Bladder Cancer in Patients with Liver Cirrhosis: A Review of Pertinent Considerations

The incidence of liver cirrhosis is increasing worldwide. Patients with cirrhosis are generally at a higher risk of harbouring hepatic and non-hepatic malignancies, including bladder cancer, likely due to the presence of related risk factors such as smoking. Cirrhosis can complicate both the operative and non-surgical management of bladder cancer. For example, cirrhotic patients undergoing abdominal surgery generally demonstrate worse postoperative outcomes, and chemotherapy in patients with cirrhosis often requires dose reduction due to its direct hepatotoxic effects and reduced hepatic clearance. Multiple other considerations in the peri-operative management for cirrhosis patients with muscle-invasive bladder cancer must be taken into account to optimize outcomes in these patients. Unfortunately, the current literature specifically related to the treatment of cirrhotic bladder cancer patients remains sparse. We aim to review the literature on treatment considerations for this patient population with respect to perioperative, surgical, and adjuvant management.

Management of Gallstones and Acute Cholecystitis in Patients with Liver Cirrhosis: What Should We Consider When Performing Surgery?

Acute cholecystitis and several gallbladder stone-related conditions, such as impacted common bile duct stones, cholangitis, and biliary pancreatitis, are common medical conditions in daily practice. An early cholecystectomy or drainage procedure with delayed cholecystectomy is the current standard of treatment based on published clinical guidelines. Cirrhosis is not only a condition of chronically impaired hepatic function but also has systemic effects in patients. In cirrhotic individuals, several predisposing factors, including changes in the bile acid composition, increased nucleation of bile, and decreased motility of the gallbladder, contribute to the formation of biliary stones and the possibility of symptomatic cholelithiasis, which is an indication for surgical treatment. In addition to these predisposing factors for cholelithiasis, systemic effects and local anatomic consequences related to cirrhosis lead to anesthesiologic risks and perioperative complications in cirrhotic patients. Therefore, the treatment of the aforementioned biliary conditions in cirrhotic patients has become a challenging issue. In this review, we focus on cholecystectomy for cirrhotic patients and summarize the surgical indications, risk stratification, surgical procedures, and surgical outcomes specific to cirrhotic patients with symptomatic cholelithiasis.

Nonalcoholic Fatty Liver Disease after Liver Transplant

Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease in the world. The rising prevalence of nonalcoholic steatohepatitis (NASH) has led to a 170% increase in NASH cirrhosis as the listing indication for liver transplantation from 2004 to 2013. As of 2018, NASH has overtaken hepatitis C as an indication for liver transplantation in the USA. After liver transplantation, the allograft often develops recurrent NAFLD among patients with known NASH cirrhosis. In addition to recurrent disease, de novo NAFLD has been reported in patients with other indications for liver transplantation. In this review, we will discuss the risk factors associated with recurrent and de novo NAFLD, natural course of the disease, and management strategies after liver transplantation.

Mortality After Extrahepatic Gastrointestinal and Abdominal Wall Surgery in Patients With Alcoholic Liver Disease: A Systematic Review and Meta-Analysis

AIMS

This meta-analysis aimed to define the perioperative risk of mortality in patients with alcoholic liver disease (ALD) undergoing extrahepatic gastrointestinal surgery.

METHODS

Systematic searches of Embase, Medline and CENTRAL were undertaken to identify studies reporting about patients with ALD undergoing extrahepatic gastrointestinal surgery published since database inception to January 2019. Studies were only considered if they reported on mortality as an outcome. Pooled analysis of mortality was stratified as benign and malignant surgery and specific operative procedures where feasible.

RESULTS

Of the 2899 studies identified, only five studies met inclusion criteria, representing cholecystectomy (one study), umbilical hernia repair surgery (one study) and oesophagectomy (three studies). The total number of patients with ALD in these studies was 172. Therefore, any study on liver disease patients undergoing extrahepatic surgery that crucially included a subset with alcohol aetiology was included as a secondary analysis even though they failed to stratify mortality by underlying aetiology. The total number of studies that met this expanded inclusion criteria was 62, reporting on 37,703 patients with liver disease of which 1735 (4.5%) had a definite diagnosis of ALD. Meta-analysis of proportions of in-hospital mortality in patients with ALD undergoing upper gastrointestinal cancer surgery (oesophagectomy) was 23% [95% confidence interval (CI) 14-35%, I2 = 0%]. In-hospital mortality following oesophagectomy in liver disease patients of all aetiologies was lower, 14% (95% CI 9-21%, I2 = 41.1%).

CONCLUSION

Postoperative in-hospital mortality is high in patients with liver disease and ALD in particular. However, the currently available evidence on ALD is limited and precludes definitive conclusions on postoperative mortality risk.

Bariatric Surgery in Patients with Cirrhosis: Careful Patient and Surgery-Type Selection Is Key to Improving Outcomes

PURPOSE

Previous reports suggest an increased mortality in cirrhotic patients undergoing bariatric surgery (BS). With advancements in management of BS, we aim to study the trends, outcomes, and their predictors in patients with cirrhosis undergoing BS.

MATERIALS AND METHODS

A retrospective study was performed using the National Database from 2008 to 2013. Outcomes of BS in patients with cirrhosis were studied. In-hospital mortality, length of stay, and cost of care were compared between patients with no cirrhosis (NC), compensated cirrhosis (CC), and decompensated cirrhosis (DC). Multivariable logistic regression analysis was performed to study the predictors of mortality.

RESULTS

Of the 558,017 admissions of patients who underwent BS during the study period, 3086 (0.55%) had CC and 103 (0.02%) had DC. An upward trend of vertical sleeve gastrectomy (VSG) utilization was seen during the study period. On multivariate analysis, mortality in CC was comparable with those in NC (aOR 1.88; CI 0.65-5.46); however, it was higher in DC (aOR 83.8; CI 19.3-363.8). Other predictors of mortality were older age (aOR 1.06; CI 1.04-1.08), male (aOR 2.59; CI 1.76-3.81), Medicare insurance (aOR 1.93; CI 1.24-3.01), lower income (aORs 0.44 to 0.55 for 2nd to 4th income quartile vs. 1st quartile), > 3 Elixhauser Comorbidity Index (aOR 5.30; CI 3.45-8.15), undergoing Roux-en-Y gastric bypass as opposed to VSG (aOR 3.90; CI 1.79-8.48), and centers performing < 50 BS per year (aOR 5.25; CI 3.38-8.15). Length of stay and hospital cost were also significantly higher in patients with cirrhosis as compared with those with NC.

CONCLUSION

Patients with compensated cirrhosis can be considered for bariatric surgery. However, careful selection of patients, procedure type, and volume of surgical center is integral in improving outcomes and healthcare utilization in patients with cirrhosis undergoing BS.

Bariatric Surgery in Cirrhotic Patients: a Matched Case-Control Study

INTRODUCTION

Laparoscopic bariatric surgery (LBS) in liver end-stage organ disease has been proven to improve organ function and patients' symptoms. A series of LBS in patients with cirrhosis have shown good results in weight loss, but increased risk of complications. Current literature is based on clinical series. This paper aims to compare LBS (69% gastric bypass) between patients with cirrhosis and without cirrhosis.

METHODS

We conducted a retrospective 1:3 matched case-control study including bariatric patients with cirrhosis and without cirrhosis. Demographics, operative variables, postoperative complications, long-term weight loss, and comorbidity resolution were compared between groups.

RESULTS

Sixteen Child A patients were included in the patients with cirrhosis (PC) group and 48 in patients without cirrhosis (control) group. Mean age was 50 years; preoperative BMI was 39 ± 6.8 kg/m². Laparoscopic gastric bypass and laparoscopic sleeve gastrectomy were performed in 69% and 31%, respectively. Follow-up was 81% at 2 years for both groups. PC group had a higher rate of overall (31% vs. 6%; p < 0.05) and severe (Clavien-Dindo ≥ III; 13% vs. 0%; p = 0.013) complications than that of the control group. Mean %EWL of PC at 2 years of follow-up was 84.9%, without differences compared with that of the control group (83.1%). Comorbidity remission in PC was 14%, 50%, and 85% for hypertension, type 2 diabetes, and dyslipidemia, respectively. Patients without cirrhosis had a higher resolution rate of hypertension (65% vs. 14%, p = 0.03).

CONCLUSION

LBS is effective for weight loss and comorbidity resolution in patients with obesity and Child A liver cirrhosis. However, these results are accompanied by significantly increased risk of complications.

Laparoscopic Liver Surgery: What Are the Advantages in Patients with Cirrhosis and Portal Hypertension? Systematic Review and Meta-Analysis with Personal Experience

Background: Laparoscopic surgery is a choice of treatment for liver diseases; it can decrease postoperative morbidity and length of hospital stay (LOS). Hepatocellular carcinoma (HCC) in patients with cirrhosis and portal hypertension may benefit from minimally invasive liver resections (MILRs) instead of open liver resections (OLRs). Whether minimally invasive approaches are superior to conventional ones is still a matter of debate. We thus aimed to gather the available literature on this specific topic to achieve greater clarity. Materials and Methods: PubMed, EMBASE and Web of Sciences databases were assessed for studies comparing OLRs versus MILRs for HCC in cirrhotic patients up to February 2020. Data from our surgical experience from June 2010 to February 2020 were also included. Demographic characteristics, liver function, the presence of portal hypertension, tumor number, and tumor size and location were assessed; operative time, need for Pringle maneuver, estimated blood loss (EBL), major or minor hepatectomy performance, and conversion rate were evaluated for operative findings. Postoperative outcomes and liver-related complications, surgical site infection (SSI) rate, blood transfusion (BT) rate, need for reintervention, LOS, in-hospital or 30-day mortality, and radicality of resection were also considered. Meta-analysis was performed employing Review Manager 5.3 software. Results: One thousand three hundred twenty-one patients from 13 studies and our own series were considered in the meta-analysis. At preoperative settings, the OLR and MILR groups differed significantly only by tumor size (4.4 versus 3.0, P = .006). Laparoscopic procedures resulted significantly faster (120.32-330 minutes versus 146.8-342.75 minutes, P = .002) and with lower EBL than open ones (88-483 mL versus 200-580 mL, P < .00001), thus requiring less BTs (7.9% versus 13.2%, P = .02). In terms of overall morbidity, minimally invasive surgeries resulted significantly favorable (19.32% versus 38.04%, P < .00001), as well as for ascites (2.7% versus 12.9% P < .00001), postoperative liver failure (7.51% versus 13.61% P = .009), and SSI (1.8% versus 5.42%, P = .002). Accordingly, patients who had undergone MILRs had significantly shorter postoperative hospitalization than patients who underwent conventional open surgery (2.4-36 days versus 4.2-19 days P < .00001). Both groups did not differ in terms of mortality rate and radicality of resection (OLR 93.8% versus 96.1% laparoscopic liver resection, P = .12). Conclusions: Based on the available evidence in the literature, laparoscopic resections rather than open liver ones for HCC surgery in cirrhotic patients seem to reduce postoperative overall morbidity, liver-specific complications, and LOS. The lack of randomized studies on this topic precludes the possibility of achieving defining statements.

A pre-operative platelet transfusion algorithm for patients with cirrhosis and hepatocellular carcinoma undergoing laparoscopic microwave ablation

BACKGROUND

Thrombocytopenia is a common finding in patients with chronic liver disease. It is associated with poor clinical outcomes due to increased risk of bleeding after even minor procedures. We sought to determine an algorithm for pre-operative platelet transfusion in patients with cirrhosis and hepatocellular carcinoma (HCC) undergoing laparoscopic microwave ablation (MIS-MWA).

METHODS

A retrospective review identified all patients with cirrhosis and HCC who underwent MIS-MWA at a single tertiary institution between 2007 and 2019. Demographics, pre-operative and post-operative laboratory values, transfusion requirements, and bleeding events were collected. The analyzed outcome of bleeding risk included any transfusion received intra-operatively or a transfusion or surgical intervention post-operatively. Logistic regression models were created to predict bleeding risk and identify patients who would benefit from pre-operative transfusion.

RESULTS

There were 433 patients with cirrhosis and HCC who underwent MIS-MWA identified; of these, 353 patients had complete laboratory values and were included. Bleeding risk was evaluated through bivariate analysis of statistically and clinically significant variables. The accuracy of both models was substantiated through bootstrap validation for 500 iterations (model 1: ROC 0.8684, Brier score 0.0238; model 2: ROC 0.8363, Brier score 0.0252). The first model captured patients with both thrombocytopenia and anemia: platelet count < 60 × 10⁹ / L (OR 7.75, p 0.012, CI 1.58-38.06) and hemoglobin < 10 gm/dL (OR 5.76, p 0.032, CI 1.16-28.63). The second model captured patients with thrombocytopenia without anemia: platelet count < 30 × 10⁹/L (OR 8.41, p 0.05, CI 0.96-73.50) and hemoglobin > 10 gm/dL (OR 0.16, p 0.026, CI 0.031-0.80).

CONCLUSION

The prediction of patients with cirrhosis and HCC requiring pre-operative platelet transfusions may help to avoid bleeding complications after invasive procedures. This study needs to be prospectively validated and ultimately may be beneficial in assessment of novel therapies for platelet-based clinical treatment in liver disease.

Asymptomatic Intestinal Malrotation Progressing to Midgut Volvulus in a Decompensated Alcoholic Cirrhotic Adult: A Rare Scenario Requiring Special Considerations

Intestinal malrotation usually presents in the pediatric population with midgut volvulus requiring emergency Ladd's procedure. Rarely, it remains asymptomatic and is discovered incidentally only during adulthood when it seldom causes intestinal complications. The scenario of a cirrhotic adult being diagnosed with asymptomatic intestinal malrotation with subsequent intestinal complications is thus extremely rare and to our knowledge has not been previously reported. We describe a 56-year-old man with decompensated alcoholic cirrhosis (Child-Pugh class C, MELD score 22) who was initially observed after an incidental diagnosis of intestinal malrotation on computed tomography. Observation continued as his liver disease improved with alcohol cessation (Child-Pugh class A, MELD score 8). He later presented with a closed loop bowel obstruction secondary to midgut volvulus at the time of alcohol relapse and liver redecompensation (Child-Pugh class C, MELD score 22-29). He underwent emergency Ladd's procedure during which his midjejunum was volvulized into an internal hernia space created by a thick Ladd's band containing large varices. The postoperative course was complicated by ileus and loculated bacterial peritonitis. Based on our experience, we discuss special considerations with regard to the surgical technique and timing of Ladd's procedure when encountering intestinal malrotation in a cirrhotic adult with portal hypertension.

Laparoscopic cholecystectomy in patients with liver cirrhosis: 8 years experience in a tertiary center. A retrospective cohort study

With improved laparoscopic techniques, experience, and availability of newer tools and instruments like ultrasonic shears; laparoscopic cholecystectomy (LC) became a feasible option in cirrhotic patients, the aim of this study was to analyze the outcome of LC in cirrhotic patients.

METHODS

We retrospectively analyzed 213 cirrhotic patients underwent LC, in the period from 2011 to 2019; the overall male/female ratio was 114/99.

RESULTS

The most frequent Child-Turcotte-Pugh (CTP) score was A, The most frequent cause of cirrhosis was hepatitis C virus (HCV), while biliary colic was the most frequent presentation. The harmonic device was used in 39.9% of patients, with a significant correlation between it and lower operative bleeding, lower blood and plasma transfusion rates, higher operative adhesions rates, lower conversion to open surgery and 30-day complication rates, shorter operative time and post-operative hospital stays where operative adhesions and times were independently correlated. The 30-day morbidity and mortality were 22.1% and 2.3% respectively while overall survival was 91.5%, higher CTP, and model for end-stage liver disease (MELD) scores, higher mean international normalization ratio (INR) value, lower mean platelet count, higher operative bleeding, higher blood, and plasma transfusion rates, longer mean operative time and postoperative hospital stays were significantly correlated with all conversion to open surgery, 30-day morbidities and mortalities.

CONCLUSION

LC can be safely performed in cirrhotic patients. However, higher CTP and MELD scores, operative bleeding, more blood and plasma transfusion units, longer operative time, lower platelet count, and higher INR values are predictors of poor outcome that can be improved by proper patient selection and meticulous peri-operative care and by using Harmonic scalpel shears.

Liver Transplantation for Nonalcoholic Steatohepatitis: Pathophysiology of Recurrence and Clinical Challenges

Nonalcoholic steatohepatitis is the fastest-growing indication for the liver transplant and a leading cause of hepatocellular carcinoma among patients listed for liver transplantation in the USA. Post-transplant nonalcoholic hepatic steatosis and steatohepatitis are frequent complications of liver transplantation. Nonalcoholic steatohepatitis poses a significant challenge in both pre- and post-transplant period due to its association with metabolic syndrome, coronary artery disease, chronic kidney disease, and obstructive sleep apnea. While optimal therapy is not yet available in the post-liver transplant setting, lifestyle interventions continue to remain as the mainstay of therapy for post-transplant nonalcoholic steatohepatitis. Early recognition with protocol biopsies and noninvasive modalities, along with modification of known risk factors, are the most effective methods to curtail the progression of nonalcoholic steatohepatitis in the absence of FDA-approved pharmacologic therapy.

Laparoscopic totally extraperitoneal (TEP) inguinal hernia repair in patients with liver cirrhosis accompanied by ascites

To investigate the feasibility, efficacy, and safety of laparoscopic totally extraperitoneal (TEP) repair in patients with inguinal hernia accompanied by liver cirrhosis.Between October 2015 and May 2018, 17 patients with liver cirrhosis who underwent TEP repair were included in this study. The baseline characteristics, perioperative data, and recurrence were retrospectively reviewed.Seventeen patients with a mean duration of 18.23 ± 16.80 months were enrolled. All TEP repairs were successful without conversion to trans-abdominal pre-peritoneal (TAPP) surgery or open repair, but 4 patients had peritoneum rupture during dissection. The mean operation time was 54.23 ± 10.51 minutes for unilateral hernia and 101.25 ± 13.77 minutes for bilateral hernias. We found 2 cases with contralateral inguinal hernia and 2 cases with obturator hernia during surgery. The rate of complication was 17.65% (3/17), 2 of 3 cases were Child-Turcotte-Pugh C with large ascites. During a follow-up of 19.29 ± 9.01 months, no patients had recurrence and chronic pain, but 2 patients died because of the progression of underlying liver disease.Early and elective inguinal hernia repair is feasible and effective for patients with liver cirrhosis. TEP is a feasible and safe repair option for cirrhotic patients in experienced hands.

Risk Assessment of Laparoscopic Cholecystectomy in Liver Cirrhotic Patients with Clinically Significant Portal Hypertension: A Retrospective Cohort Study

Objective: This study was aimed to evaluate the correlation between clinically significant portal hypertension (CSPH) and postoperative complications and risk predictors of postoperative complications. Methods: The retrospective study was conducted to identify the effect. The cirrhotic patients were divided into two groups, those with or without CSPH. The intraoperative and postoperative conditions were evaluated. Multivariate logistic regression analysis was performed to identify potential risk predictors for postoperative complications in cirrhotic patients with CSPH. Results: The cirrhotic patients with CSPH who underwent laparoscopic cholecystectomy (LC) had postoperative hospitalization than the patients without CSPH. However, the incidence of postoperative complications between two groups showed no significant difference. The results of multivariate analysis showed that male, gallbladder wall >3 mm, size of stones ≥1 cm, scores of Model for end-stage liver disease (MELD) ≥10, and operation time >60 minutes were the potential risk predictors for postoperative complications. Conclusions: CSPH did not increase the incidence of postoperative complications in cirrhotic patients who underwent LC, but increased conversion rate and prolonged postoperative hospitalization. Furthermore, our study showed that gender, sizes of gallbladder wall and stones, scores of MELD, and operation time were the important postoperative risk predictors for cirrhotic patients with CSPH.

Non-Hepatic Abdominal Surgery in Patients with Cirrhotic Liver Disease

Cirrhotic liver disease is an important cause of peri-operative morbidity and mortality in general surgical patients. Early recognition and optimization of liver dysfunction is imperative before any elective surgery. Patients with MELD <12 or classified as Child A have a higher morbidity and mortality than matched controls without liver dysfunction, but are generally safe for elective procedures with appropriate patient education. Patients with MELD >20 or classified as Child C should undergo transplantation before any elective procedure given mortality exceeds 40%. Laparoscopic procedures are feasible and safe in cirrhotic patients.

Considerations for bariatric surgery in patients with cirrhosis

With the ever increasing global obesity pandemic, clinical burden from obesity related complications are anticipated in parallel. Bariatric surgery, a treatment approved for weight loss in morbidly obese patients, has reported to be associated with good outcomes, such as reversal of type two diabetes mellitus and reducing all-cause mortality on a long term basis. However, complications from bariatric surgery have similarly been reported. In particular, with the onslaught of non-alcoholic fatty liver disease (NAFLD) epidemic, in associated with obesity and metabolic syndrome, there is increasing prevalence of NAFLD related liver cirrhosis, which potentially connotes more risk of specific complications for surgery. Bariatric surgeons may encounter, either expectedly or unexpectedly, patients with non-alcoholic steatohepatitis (NASH) and NASH related cirrhosis more frequently. As such, the issues and considerations surrounding their medical care/surgery warrant careful deliberation to ensure the best outcomes. These considerations include severity of cirrhosis, liver synthetic function, portal hypertension and the impact of surgical factors. This review explores these considerations comprehensively and emphasizes the best approach to managing cirrhotic patients in the context of bariatric surgery.

Benefits of Laparoscopic Approach for Resection of Liver Tumors in Cirrhotic Patients

INTRODUCTION

Liver resection in cirrhotic patients is associated with increased morbidity and mortality. The objective of this study was to compare short-term results of laparoscopic resection (LR) and open surgery (OS) for minor liver resection in patients with hepatocellular carcinoma (HCC) hepatocellularcarcinoma on nontumor cirrhotic liver (HCC/F4) and patients with colorectal cancer liver metastases (CRLMs) colorectal liver metastases on healthy liver (CRLM/F0).

MATERIALS AND METHODS

Between January 2005 and December 2014, all patients undergoing liver resection (n = 754) were included in this study. Liver resections for cholangiocarcinoma or benign tumor, major liver resection (≥3 segments), HCC on healthy liver, CRLM on cirrhotic liver, and liver resection with technically difficult accessibility (segments I, VII, and VIII) were excluded. The primary endpoint of the study was a validated composite endpoint (CEP), which included specific liver surgery complications (Clavien ≥III), allowing comparison of the postoperative course after LR versus OR for HCC/F4 patients and CRLM/F0 patients using propensity score (PS) analysis. Secondary endpoints were major postoperative morbidity according to the Clavien-Dindo classification (≥III) and intensive care unit (ICU) length of hospital stay (LOS) and overall LOS. The test group was defined as HCC/F4 patients operated by LR, and the control group was defined as HCC/F4 patients and CRLM/F0 patients operated by OS and CRLM/F0 patient operated by LR.

RESULTS

Sixty patients (38.7%) underwent LR and 95 patients (61.3%) underwent OS. Surgery was performed for CRLM in 93 patients (60%) and for HCC in 62 patients (40%). No difference was demonstrated between HCC/F4 patients and CRLM/F0 patients in the LR group in terms of the CEP (7% versus 18.1%; P = .23), while a significant difference for the CEP was observed between HCC/F4 patients and CRLM/F0 patients after OS (50% versus 21%; P = .021). A higher rate of CEP was observed for HCC/F4 patients operated by OS compared to HCC/F4 patients operated by LR (50% versus 7.8%; P = .009). No significant difference in Clavien-Dindo score ≥III was observed between HCC/F4 patients and CRLM/F0 patients operated by LR (10% versus 4.5%; P = .98). A higher postoperative ascites rate was observed for HCC/F4 patients operated by OS compared to CRLM/F0 patients operated by OS (25% versus 2.8%; P = .006). This difference was no longer observed when HCC/F4 patients were compared to CRLM/F0 operated by LR (7.8% versus 2.8%; P = .09). The postoperative mortality rate was 1.8% and was not correlated with nontumor liver or surgical approach. A shorter LOS was observed for HCC/F4 patients operated by LR compared to HCC/F4 patients operated by OS (7.53 versus 17.13; P = .011).

CONCLUSION

The laparoscopic approach for malignant liver tumor is associated with a lower specific complication rate. LR for HCC/F4 could eliminate excess morbidity and decrease LOS in patients with cirrhotic liver.

Laparoscopic splenectomy: Current concepts

Since early 1990’s, when it was inaugurally introduced, laparoscopic splenectomy has been performed with excellent results in terms of intraoperative and postoperative complications. Nowadays laparoscopic splenectomy is the approach of choice for both benign and malignant diseases of the spleen. However some contraindications still apply. The evolution of the technology has allowed though, cases which were considered to be absolute contraindications for performing a minimal invasive procedure to be treated with modified laparoscopic approaches. Moreover, the introduction of advanced laparoscopic tools for ligation resulted in less intraoperative complications. Today, laparoscopic splenectomy is considered safe, with better outcomes in comparison to open splenectomy, and the increased experience of surgeons allows operative times comparable to those of an open splenectomy. In this review we discuss the indications and the contraindications of laparoscopic splenectomy. Moreover we analyze the standard and modified surgical approaches, and we evaluate the short-term and long-term outcomes.

The role of bariatric surgery in nonalcoholic fatty liver disease and nonalcoholic steatohepatitis

Nonalcoholic fatty liver disease (NAFLD) affects between 25% and 33% of the population, is more common in obese individuals, and is the most common cause of chronic liver disease in the United States. However, despite rising prevalence, effective treatments remain limited. Areas covered: We performed a literature search across multiple databases (Pubmed, Medline, etc.) to identify significant original research and review articles to provide an up-to-date and concise overview of disease pathogenesis and diagnostic evaluation and to expand on available treatment options with a specific focus on the potential role of bariatric surgery. Here we provide the most comprehensive review of bariatric surgery for the management of NAFLD, noting benefits from different procedures and multiple reports showing improvements in steatosis, inflammation and fibrosis over the duration of follow-up. Expert commentary: The morbidity of NAFLD is significant as it may become the most common indication for liver transplantation within the next 5 years. In addition to known benefits of weight loss and diabetes resolution, bariatric surgery has the potential to halt and reverse disease progression and future controlled trials should be performed to further define its benefit in the treatment of NAFLD in morbidly obese patients.

Comparison of long-term survival and immediate postoperative liver function after laparoscopic and open distal gastrectomy for early gastric cancer patients with liver cirrhosis

BACKGROUND

Several studies have suggested no difference in the liver function of early gastric cancer (EGC) patients with liver cirrhosis (LC) between laparoscopic and open distal gastrectomy. However, the number of patients and comparison of long-term survival rates between the two groups are limited. The purpose of this study was to compare the long-term survival and immediate postoperative liver function of EGC patients with LC after laparoscopic and open distal gastrectomy.

MATERIALS AND METHODS

The clinical data of EGC patients with LC who had no other malignancy and underwent distal gastrectomy at Asan Medical Center between January 2005 and April 2013 were investigated retrospectively. All patients were divided into two groups: the open group (OG) and laparoscopic group (LG). The clinicopathologic data of the two groups were compared.

RESULTS

The number of patients in each group was 48 and 27 in the OG and LG, respectively. There were no significant differences in the age, sex ratio, ASA score, cause of liver cirrhosis, preoperative Child-Pugh classification, tumor location, TNM stage, total postoperative drain amount, albumin, total bilirubin, alkaline phosphatase, alanine aminotransferase, prothrombin time, morbidity and recurrence rate. Shorter hospital stay, longer operative time and more retrieved lymph nodes were observed in LG. The long-term overall survival rate was not different between the two groups (P = 0.356).

CONCLUSIONS

For EGC patients with liver cirrhosis, especially Child A cirrhosis, laparoscopic or laparoscopy-assisted distal gastrectomy can be a safe surgical procedure in comparison to open distal gastrectomy in terms of the long-term survival rate and immediate postoperative liver function.

Liver Transplantation and Bariatric Surgery: Best Approach

Obesity has become increasingly prevalent, and the number of obese patients in need of liver transplant is expected to continue to increase. In addition, liver disease due to nonalcoholic fatty liver disease is expected to become the leading cause of liver transplantation in the near future. However, obesity remains a relative contraindication in liver transplant. New strategies in managing this patient population are clearly needed. To this end, the authors review the current literature on the efficacy of bariatric surgery in the setting of liver transplantation in obese patients.

Management of Thrombocytopenia in Chronic Liver Disease: Focus on Pharmacotherapeutic Strategies

Thrombocytopenia (platelet count <150 × 10⁹/L) often complicates chronic liver disease, impeding optimal management of these patients. The prevalence of this manifestation ranges from 6 % among non-cirrhotic patients with chronic liver disease to 70 % among patients with liver cirrhosis. It has also been shown that the severity of liver disease is associated with both prevalence and level of thrombocytopenia. Its development is often multifactorial, although thrombopoietin is thought to be a major factor. The discovery of and ability to clone thrombopoietin led to new treatment opportunities for this clinical manifestation. This review discusses data on the three most important thrombopoietin receptor agonists: eltrombopag, avatrombopag, and romiplostim. Currently, only eltrombopag is approved for usage among patients with thrombocytopenia and chronic hepatitis C virus infection in order to initiate and maintain interferon-based antiviral treatment. Nevertheless, the optimal management of hematologic abnormalities among patients with chronic liver disease, and its risk for bleeding complications, is still a matter of discussion. Thrombocytopenia definitely contributes to hemostatic defects but is often counterbalanced by the enhanced presence of procoagulant factors. Therefore, a thorough assessment of the patient’s risk for thrombotic events is essential when the use of thrombopoietin receptor agonists is considered among patients with chronic liver disease and thrombocytopenia.

Laparoscopic versus open ventral hernia repair in patients with chronic liver disease

BACKGROUND

Previous studies demonstrated laparoscopic ventral hernia repair (LVHR) to be associated with fewer short-term complications than open ventral hernia repair (OVHR). Little literature is available comparing LVHR and OVHR in chronic liver disease (CLD) patients.

METHODS

Patients with model for end-stage liver disease score ≥9 who underwent elective ventral hernia repair in the National Surgical Quality Improvement Program Database were included. 30-day outcomes were compared between LVHR and OVHR after adjusting for hernia disease severity, baseline comorbidities and demographic factors.

RESULTS

A total of 3594 ventral hernia repairs were included, 536 (14.9 %) of which were LVHR. After adjusting for other confounders, LVHR was associated with a lower incidence of wound-related complications (0.23, 95 % CI 0.07-0.74, p = 0.01), shorter length of stay (mean 3.7 vs. 5.0 days, p < 0.01) than OVHR, but similar systemic complications (p = 0.77), bleeding complications (p = 0.69), unplanned reoperation (p = 0.74) or readmission (p = 0.40). Propensity score-matched comparison showed similar conclusions. Five hundred and sixty-two patients had ascites, among whom 35 (6.2 %) underwent LVHR. In this subcohort, LVHR was associated with higher mortality (OR 5.36, 95 % CI 1.00-28.60, p = 0.05), systemic complications (OR 7.03, 95 % CI 2.06-24.00, p < 0.01), and unplanned reoperation (OR 6.03, 95 % CI 1.51-24.12, p = 0.01) than OVHR.

CONCLUSIONS

In comparison with OVHR, LVHR is associated with similar short-term outcomes except for lower wound-related complications and shorter length of stay in CLD patients. However, when patients have ascites, LVHR is associated with higher mortality, systemic complications, and unplanned reoperation.

Outcomes of abdominal surgery in patients with liver cirrhosis

Patients suffering from liver cirrhosis (LC) frequently require non-hepatic abdominal surgery, even before liver transplantation. LC is an important risk factor itself for surgery, due to the higher than average associated morbidity and mortality. This high surgical risk occurs because of the pathophysiology of liver disease itself and to the presence of contributing factors, such as coagulopathy, poor nutritional status, adaptive immune dysfunction, cirrhotic cardiomyopathy, and renal and pulmonary dysfunction, which all lead to poor outcomes. Careful evaluation of these factors and the degree of liver disease can help to reduce the development of complications both during and after abdominal surgery. In the emergency setting, with the presence of decompensated LC, alcoholic hepatitis, severe/advanced LC, and significant extrahepatic organ dysfunction conservative management is preferred. A multidisciplinary, individualized, and specialized approach can improve outcomes; preoperative optimization after risk stratification and careful management are mandatory before surgery. Laparoscopic techniques can also improve outcomes. We review the impact of LC on surgical outcome in non-hepatic abdominal surgeries required in this cirrhotic population before, during, and after surgery.

Difficult situations in laparoscopic cholecystectomy: a multicentric retrospective study

INTRODUCTION

Difficult laparoscopic cholecystectomy (LC) is the most common "difficult" surgical procedure performed today, which possesses the potential to place the patient at significant operative risk. We present our retrospective study and experience of 8347 patients with LC since June 1995 to December 2011 at 2 large centers: Mariampur and GSVM Medical College, LLR Hospital, Kanpur, with discussions regarding the practical aspects of LC in difficult situations with respect to conversion to open cholecystectomy.

METHODS

A retrospective analysis of patients who underwent LC from June 1995 to December 2011 was performed. The analysis was performed in relation to the need for conversion and the factors responsible for conversion.

RESULTS

Out of 8347 cases, 2187 cases (26.2%) were identified as difficult. LC was performed successfully in 8265 cases (total completion rate, 99.02%). Of the 2187 difficult cases, LC was completed successfully in 2105 cases (completion rate in difficult cases, 96.25%) and converted to open cholecystectomy in 82 cases (conversion rate in difficult cases, 3.75%).

CONCLUSIONS

Because of the increasing exposure and expertise of surgeons dealing with complex gall bladder laparoscopies, rates of conversion to open cholecystectomy are decreasing and many difficult cases are now handled laparoscopically. However, if required, conversion should not be considered as a failure for the benefit of the patient.

Laparoscopic ventral/incisional hernia repair: updated Consensus Development Conference based guidelines [corrected]

BACKGROUND

The Executive board of the Italian Society for Endoscopic Surgery (SICE) promoted an update of the first evidence-based Italian Consensus Conference Guidelines 2010 because a large amount of literature has been published in the last 4 years about the topics examined and new relevant issues.

METHODS

The scientific committee selected the topics to be addressed: indications to surgical treatment including special conditions (obesity, cirrhosis, diastasis recti abdominis, acute presentation); safety and outcome of intraperitoneal meshes (synthetic and biologic); fixing devices (absorbable/non-absorbable); abdominal border and parastomal hernia; intraoperative and perioperative complications; and recurrent ventral/incisional hernia. All the recommendations are the result of a careful and complete literature review examined with autonomous judgment by the entire panel. The process was supervised by experts in methodology and epidemiology from the most qualified Italian institution. Two external reviewers were designed by the EAES and EHS to guarantee the most objective, transparent, and reliable work. The Oxford hierarchy (OCEBM Levels of Evidence Working Group*. "The Oxford 2011 Levels of Evidence") was used by the panel to grade clinical outcomes according to levels of evidence. The recommendations were based on the grading system suggested by the GRADE working group.

RESULTS AND CONCLUSIONS

The availability of recent level 1 evidence (a meta-analysis of 10 RCTs) allowed to recommend that not only laparoscopic repair is an acceptable alternative to the open repair, but also it is advantageous in terms of shorter hospital stay and wound infection rate. This conclusion appears to be extremely relevant in a clinical setting. Indications about specific conditions could also be issued: laparoscopy is recommended for the treatment of recurrent ventral hernias and obese patients, while it is a potential option for compensated cirrhotic and childbearing-age female patients. Many relevant and controversial topics were thoroughly examined by this consensus conference for the first time. Among them are the issue of safety of the intraperitoneal mesh placement, traditionally considered a major drawback of the laparoscopic technique, the role for the biologic meshes, and various aspects of the laparoscopic approach for particular locations of the defect such as the abdominal border or parastomal hernias.

The influence of mesh topology in the abdominal wall repair process

The tissue integration and the formation of adhesions in the repair of abdominal wall defects are principally led to the topology and the mechanical properties of implanted prosthesis. In this study we analyzed the influence of the topology of the meshes for abdominal wall repair, made of polypropylene (PP), evaluating its ability to prevent and to minimize the formation of adhesions, and to promote tissue ingrowth. Two series of in vivo studies were performed. In the first, two types of PP meshes, a lightweight macroporous mesh (LWM) and a heavyweight microporous mesh (HWM) were compared with determine the optimal porosity for tissue integration. In the second, a composite mesh, Clear Mesh Composite (CMC), made of a LWM sewn on a PP planar smooth film, was compared with a PP planar film, to demonstrate how two different topologies of same material are able to induce different tissue integration with the abdominal wall and different adhesion with internal organs. In both studies, the prostheses were implanted in Wistar rats and histological analysis and mechanical characterization of tissue coupled with the implants were performed. LWM showed better host tissue ingrowth in comparison to HWM. CMC prosthesis showed no adhesions to the viscera and no strong foreign body reaction, moreover its elasticity and anisotropy index were more similar to that of natural tissue. These results demonstrated that the surface morphology of PP surgical meshes allowed to modulate their repair ability. © 2015 Wiley Periodicals, Inc.

Non-hepatic gastrointestinal surgery in patients with cirrhosis

Gastrointestinal surgery is feasible in patients with Child A cirrhosis, but is associated with higher morbidity and mortality. Hernia repair, biliary and colonic surgery are the most frequently performed interventions in this context. Esophageal and pancreatic surgery are more controversial and less frequently performed. For patients with decompensated liver function (Child B or C patients), the indications for surgery should be discussed by a multi-specialty team including the hepatologist, anesthesiologist, surgeon; liver function should be optimized if possible. During emergency surgery, histologic diagnosis of cirrhosis should be confirmed by liver biopsy because the histologic diagnosis has therapeutic and prognostic implications. The management of patients with Child A cirrhosis without portal hypertension is little different from the management of patients without cirrhosis. However, the management of patients with Child B or C cirrhosis or with portal hypertension is more complex and requires an accurate assessment of the balance of benefit vs. risk for surgical intervention on a case-by-case basis.

Surgery in patients with portal hypertension: a preoperative checklist and strategies for attenuating risk

Patients with liver disease and portal hypertension are at increased risk of complications from surgery. Recent advances have allowed better optimization of patients with cirrhosis before surgery and a reduction in postoperative complications. Despite this progress, the estimation of surgical risk in a patient with cirrhosis is challenging. The MELD score has shown promise in predicting postoperative mortality compared with the Child-Turcotte-Pugh score. This article addresses current concepts in the perioperative evaluation of patients with liver disease and portal tension, including a preoperative liver assessment (POLA) checklist that may be useful towards mitigating perioperative complications.

Delayed laparoscopic cholecystectomy is safe and effective for acute severe calculous cholecystitis in patients with advanced cirrhosis: a single center experience

Acute calculous cholecystitis is a common disease in cirrhotic patients. Laparoscopic cholecystectomy can resolve this problem but is performed based on the premise that the local inflammation must been controlled. An Initial ultrasound guided percutaneous transhepatic cholecystostomy may reduce the local inflammation and provide advantages in subsequent surgery. In this paper, we detailed our experience of treating acute severe calculous cholecystitis in patients with advanced cirrhosis by delayed laparoscopic cholecystectomy plus initiated ultrasound guided percutaneous transhepatic cholecystostomy and provided the analysis of the treatment effect. We hope this paper can provided a kind of standard procedure for this special disease; however, further prospective comparative randomized trials are needed to assess this treatment in cirrhotic patients with acute cholecystitis.

Laparoscopic Versus Open Splenectomy for Portal Hypertension

Background. Laparoscopic splenectomy has become the gold-standard procedure for normal to moderately enlarged spleens. However, the safety of laparoscopic splenectomy for patients with portal hypertension remains controversial. We carried out this systematic review to identify the feasibility and safety of laparoscopic splenectomy in treating portal hypertension. Data sources. A systematic search for comparative studies that compared laparoscopic splenectomy with open splenectomy for portal hypertension was carried out. Studies were independently reviewed for quality, inclusion and exclusion criteria, demographic characteristics, and perioperative outcomes. Conclusion. Although laparoscopic splenectomy is associated with longer operating time, it offers advantages over the open procedure in terms of less blood loss, lower operative complications, earlier resumption of oral intake, and shorter posthospital stay. Therefore, laparoscopic splenectomy is a safe and feasible intervention for portal hypertension.

Surgical management of obesity in patients with morbid obesity and nonalcoholic fatty liver disease

Most patients with severe complex obesity presenting for bariatric-metabolic surgery have nonalcoholic fatty liver disease (NAFLD). NAFLD is associated with central obesity, insulin resistance, type 2 diabetes, hypertension, and obesity-related dyslipidemia. Weight loss should be a primary therapy for NAFLD. However, evidence supporting intentional weight loss as a therapy for NAFLD is limited. Bariatric-metabolic surgery provides the most reliable method of achieving substantial sustained weight loss and the most commonly used procedures are associated with reduced steatosis and lobular inflammatory changes, but there are mixed reports regarding fibrosis. Surgery should complement treatment of obesity-related comorbidity, but not replace established therapy.

Consecutive laparoscopic gallbladder and spleen resections in cirrhotic patients

AIM: To evaluate the feasibility, safety, and effectiveness of consecutive laparoscopic cholecystectomy (LC) plus splenectomy (LS) in liver cirrhosis patients.

METHODS: From 2003 to 2013, 17 (group 1) patients with liver cirrhosis complicated by hypersplenism and symptomatic gallstones were treated with combined LC and LS, while 58 (group 2) patients with liver cirrhosis and hypersplenism received LS alone. An additional 14 (group 3) patients who received traditional open procedures during the same period were included as controls. Data were retrospectively collected and reviewed in regard to demographic characteristics and preoperative, intraoperative and postoperative features. Differences between the three groups were assessed by statistical analysis.

RESULTS: The three groups showed no significant differences in the demographic characteristics or preoperative status. However, the patients treated with LC and LS required significantly longer operative time, shorter postoperative stay as well as shorter time of return to the first oral intake, and suffered less intraoperative blood loss as well as fewer postoperative surgical infections than the patients treated with traditional open procedures (group 1 vs group 3, P < 0.05 for all). The patients treated with LC and LS showed no significant differences in the intraoperative and postoperative variables from those treated with LS alone (group 1 vs group 2). All patients showed significant improvements in the haematological responses (preoperative period vs postoperative period, P < 0.05 for all). None of the patients treated with LC and LS presented with any gallstone-associated symptoms following discharge, while the patients treated with the traditional open procedures expressed complaints of discomfort related to their surgical incisions.

CONCLUSION: Consecutive LC and LS is an appropriate treatment option for liver cirrhosis patients with gallstones and hypersplenism, especially for those with Child-Pugh A and B.

Hand-assisted laparoscopic technique in the setting of complicated splenectomy: a 9-year experience

BACKGROUND

Laparoscopic splenectomy (LS) is significantly more challenging in patients with supramassive splenomegaly and those with portal hypertension. We hypothesized that hand-assisted laparoscopic splenectomy (HALS) could facilitate the procedure in these patients.

METHODS

Before October 2009, patients with supramassive splenomegaly and those with portal hypertension underwent LS. After October 2009, we routinely applied HALS in patients with these disorders.

RESULTS

We compared the HALS group (n = 41) with the LS group (n = 45). There were no conversions to open surgery in the HALS group, whereas there was an 4.5 % conversion rate in the LS group. The operating times were shorter, and there was less estimated blood loss, and fewer major complications in the HALS group. Analgesia requirement, time to full diet, and postoperative stay were comparable in the two groups.

CONCLUSIONS

We concluded that HALS was superior to LS in patients with supramassive splenomegaly and in those with portal hypertension.

Laparoscopic cholecystectomy in the cirrhotic patient: predictors of outcome

BACKGROUND

We sought to determine the outcome predictors of 94 cirrhotic patients undergoing laparoscopic cholecystectomy (LC).

METHODS

We performed a single-center, retrospective review of cirrhotic patients undergoing LC for symptomatic gallbladder disease. Statistical analysis was completed using the Chi-square, Wilcoxon rank-sum, and Student t tests as appropriate.

RESULTS

Ninety-four procedures were completed. The median Child-Turcotte-Pugh (CTP) score was 6 (range, 5-12), and the average Model for End-Stage Liver Disease (MELD) score was 11 ± 5. Hepatitis C was the most common etiology of liver disease (50%) followed by Laennec's cirrhosis (22%). The average length of stay was 2.6 ± 4.3 days; 21% were outpatient procedures. The conversion rate was 11%. Conversion risk factors were decreased serum albumin, increased MELD score, and blood loss. Morbidity occurred in 32 patients. Predictors of morbidity were decreases in serum albumin, increases in International Normalized Ratio (INR) and CTP score, and the number of intraoperative red blood cell transfusions. Mortality occurred in 4 patients. Increased INR, CTP score, CTP class, the number of intraoperative blood and platelet transfusions were predictors of mortality.

CONCLUSION

LC can be safely performed in cirrhotic patients with appropriate patient selection. Liver synthetic function, operative blood loss, transfusion requirement, CTP, and MELD scores may be used to predict outcomes in these patients.

Hand-assisted laparoscopic splenectomy is a better choice for patients with supramassive splenomegaly due to liver cirrhosis

BACKGROUND

The current laparoscopic splenectomy (LS) procedure used for cirrhotic patients still has limitations. The aim of our study was to determine a standard according to the splenic size for hand-assisted LS (HALS) in patients with splenomegaly and hypersplenism due to cirrhosis.

PATIENTS AND METHODS

We conducted a retrospectively review of cirrhotic patients who underwent splenectomy between 2008 and 2011. All patients were divided into two groups: Group A (19 patients), in which patients' operations were conducted by HALS, and Group B (20 patients), in which patients were treated with LS. Then the patients in Group A were classified on the basis of the spleen size: massive splenomegaly (Group A1) and supramassive splenomegaly (Group A2). Likewise, so were patients in Group B: massive splenomegaly (Group B1) and supramassive splenomegaly (Group B2). Perioperative outcomes of these patients were compared.

RESULTS

The comparison of HALS and LS based on spleen size demonstrated that in the massive splenomegaly groups, Group A1 and Group B1 had similar estimated blood loss and morbidity, and no transfusion was required in these patients. In the supramassive splenomegaly groups, compared with Group A2, Group B2 had longer operative time, more estimated blood loss, more patients requiring transfusion, and more complications that needed surgical intervention. However, no significant differences were observed in the requirement of analgesia, time of returning to oral intake, and length of hospitalization in these paired groups.

CONCLUSIONS

In cirrhotic patients with supramassive splenomegaly, HALS should be considered because of its safety, feasibility, and effectiveness.

Meta-analysis of laparoscopic versus open cholecystectomy for patients with liver cirrhosis and symptomatic cholecystolithiasis

BACKGROUND

Open cholecystectomy (OC) is often preferred over laparoscopic cholecystectomy (LC) in patients with liver cirrhosis and portal hypertension, but evidence is lacking to support this practice. This meta-analysis aimed to clarify which surgical technique is preferable for symptomatic cholecystolithiasis in patients with liver cirrhosis.

METHODS

A meta-analysis was conducted according to the PRISMA guidelines. Articles published between January 1990 and October 2011 were identified from MEDLINE, Embase and the Cochrane Library. Randomized clinical trials (RCTs) comparing outcomes of OC versus LC for cholecystolithiasis in patients with liver cirrhosis were included. The quality of the RCTs was assessed using the Jadad criteria.

RESULTS

Following review of 1422 papers by title and abstract, a meta-analysis was conducted of four RCTs comprising 234 surgical patients. They provided evidence of at least level 2b on the Oxford Level of Evidence Scale, but scored poorly according to the Jadad criteria. Some 97·0 per cent of the patients had Child-Turcotte-Pugh (CTP) grade A or B liver cirrhosis. In all, 96·6 per cent underwent elective surgery. No postoperative deaths were reported. LC was associated with fewer postoperative complications (risk ratio 0·52, 95 per cent confidence interval (c.i.) 0·29 to 0·92; P = 0·03), a shorter hospital stay (mean difference -3·05 (95 per cent c.i. -4·09 to -2·01) days; P < 0·001) and quicker resumption of a normal diet (mean difference -27·48 (-30·96 to -23·99) h; P < 0·001).

CONCLUSION

Patients with CTP grade A or B liver cirrhosis who undergo LC for symptomatic cholecystolithiasis have fewer overall postoperative complications, a shorter hospital stay and resume a normal diet more quickly than those who undergo OC.

Nonalcoholic fatty liver disease and bariatric surgery

Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease worldwide. Treatment recommendations for NAFLD are aimed towards weight reduction, thereby reducing insulin resistance. Unfortunately, lifestyle modifications have not yielded long-term success, while durable weight loss is routinely achieved with bariatric surgery. This article reviews the effects of bariatric surgery on patients with NAFLD. In these patients, postsurgical evaluations of liver histology by repeat liver biopsy are hindered by the risk of the procedure and the inherent sample variability, which makes the impact of bariatric surgery on NAFLD difficult to quantify. In longitudinal studies of NAFLD, the biopsy-based evaluations should be augmented by repeated measurements of the noninvasive biomarkers that may provide an insight into the changes in the physiological state of the liver after bariatric or other types of interventions. Nevertheless, currently available tests are not able to provide this type of in-depth outcome measures for these patients.

Laparoscopic or open cholecystectomy in cirrhosis: a systematic review of outcomes and meta-analysis of randomized trials

BACKGROUND

Cholecystectomy is associated with increased risks in patients with cirrhosis. The well-established advantages of laparoscopic surgery may be offset by the increased risk for complications relating particularly to portal hypertension and coagulopathy.

METHODS

A systematic search was undertaken to identify studies comparing open cholecystectomy (OC) and laparoscopic cholecystectomy (LC) in patients with cirrhosis. A meta-analysis was performed of the available randomized controlled trials (RCTs).

RESULTS

Forty-four studies were analysed. These included a total of 2005 patients with cirrhosis who underwent laparoscopic (n= 1756) or open (n= 249) cholecystectomy, with mortality rates of 0.74% and 2.00%, respectively. A meta-analysis of three RCTs involving a total of 220 patients was conducted. There was a reduction in the overall incidences of postoperative complications and infectious complications and a shorter length of hospital stay in LC. However, frequencies of postoperative hepatic insufficiency did not differ significantly.

CONCLUSIONS

There are few RCTs comparing OC and LC in patients with cirrhosis. These studies are small, heterogeneous in design and include almost exclusively patients with Child-Pugh class A and B disease. However, LC appears to be associated with shorter operative time, reduced complication rates and reduced length of hospital stay.

Laparoscopic cholecystectomy and liver cirrhosis

INTRODUCTION

Historically the presence of liver cirrhosis has been an absolute or relative contraindication to laparoscopic cholecystectomy (LC). Accumulating experience in LC has resulted in an increasing number of investigators reporting that LC can be safely performed in cirrhotic patients. The aim of this study was to report the efficacy and safety of LC in the treatment of symptomatic cholelithiasis in cirrhotic patients, and a review of the literature in the matter.

METHODS

Between January 2006 and July 2010, from 503 patients under LC, we reviewed 43 cirrhotic patients of Child-Pugh Classification A, B, and C, with symptomatic gallstones.

RESULTS

Conversion to an open procedure was necessary in 5 patients due to multiple factors. The mean operative time and length of hospital stay were significantly longer and higher in cirrhotic group (P<0.05). Postoperative complications were observed in 37.2% of patients. Trocar site hematoma (P=0.02), wound complications (P=0.02), and intra-abdominal collection (P=0.01) occurred more frequently in patients with cirrhosis (Child B and C class) than in patients without cirrhosis. One case of continuing hemorrhage from the gallbladder bed required a reoperation for hemostasis. Two patients with Child-Pugh class C and 1 patient with class B cirrhosis developed ascites after surgery; 1 patient with Child-Pugh class A had bile leakage. No deaths occurred.

CONCLUSIONS

LC is an effective and safe procedure and should be the treatment of choice for symptomatic cholelithiasis or cholecystitis in patients with compensated cirrhosis.
