Chemoembolization outcomes for hepatocellular carcinoma in cirrhotic patients with compromised liver function

Background

Transarterial chemoembolization (TACE) is recommended as a treatment for unresectable hepatocellular carcinoma (HCC) in patients with normal underlying liver function. The efficacy of TACE in cirrhotic patients with compromised liver function is unknown.

Methods

All ‘first’ TACE interventions for HCC performed at a single institution from 2008 to 2012 were retrospectively reviewed (n = 190). Liver function was quantified via the Child''s score. Tumour necrosis after TACE was quantified via the mRECIST criteria.

Results

The ‘first’ TACE procedures of 100 Child''s A and 90 Child''s B/C cirrhotic patients were evaluated. As expected, the lab-model for end-stage liver disease (MELD) score was significantly higher in the Child''s B/C group. Although the number of tumours were similar between the groups, both the size of the largest tumour and the total tumour diameter were greater in the Child''s A group. There were no significant differences in post-TACE tumour necrosis between groups. The median survival after TACE was significantly longer in the Child''s A compared with Child''s B/C patients (21.9 versus 13.7 months, P = 0.03).

Conclusions

TACE appears to be equally efficacious in cirrhotic patients regardless of their Child''s classification based upon equivalent mRECIST measures of tumour necrosis. However, inferior survival after TACE was observed in the Child''s B/C group.     

Laparoscopic cholecystectomy is the preferred approach in cirrhosis: a nationwide,population-based study

Background/aim

To assess the impact of open versus laparoscopic surgery in cirrhotic patients undergoing a cholecystectomy using the Nationwide Inpatient Sample (NIS).

Methods

All patients with cirrhosis who underwent a cholecystectomy (open or laparoscopic) between 2003 and 2006 were queried from the NIS. Associated complications including infection, transfusion, reoperation, liver failure and mortality were determined.

Results

A total of 3240 patients with cirrhosis underwent a cholecystectomy: 383 patients underwent an open cholecystectomy (OC) whereas 2857 patients underwent a laparoscopic cholecystectomy (LC), which included 412 patients converted (LCC) from a LC to an OC. Post-operative infection was higher in OC as opposed to a laparoscopic cholecystectomy (TLC) or LCC (3.5% versus 0.7% versus 0.2%, P < 0.0001). The need for a blood transfusion was significantly higher in the OC and LCC groups as compared with the TLC group (19.2% versus 14.4% versus 6.2%, P < 0.0001). Reoperation was more frequent after OC or LCC versus TLC (1.5% versus 2.5% versus 0.8%, P = 0.007). In-hospital mortality was higher after OC as compared with TLC and LCC (8.3% versus 1.3% versus 1.4%, P < 0.0001).

Conclusion

Patients with cirrhosis have increased in-hospital morbidity and mortality after an open as opposed to a laparoscopic or conversion to an open cholecystectomy. LC should be the preferred initial approach in cirrhotic patients.     

Patient views through the keyhole: new perspectives on single-incision vs. multiport laparoscopic cholecystectomy

Objectives

Single-incision laparoscopic cholecystectomy (SILC) may be associated with less pain, shorter hospital stay and better cosmetic results than multiport laparoscopic cholecystectomy (MLC). Advocates suggest that patients prefer SILC, although research directly addressing the question of patient preferences is limited. This study aimed to assess patient preferences using currently available evidence.

Methods

Patients awaiting elective cholecystectomy were shown a series of postoperative images taken after SILC or MLC and asked which procedure this led them to prefer. This was repeated after patients had completed a questionnaire constructed using published objective data comparing patient-reported outcomes of SILC and MLC.

Results

The study was completed by 113 consecutive patients. After their initial viewing of the images, 16% of subjects preferred MLC. Younger age, lower body mass index and female sex were associated with choosing SILC. After completing the questionnaire, 88% of patients preferred MLC (P < 0.001). Patients ranked the level of risk for complications and postoperative pain above cosmetic results in determining their choice of procedure.

Conclusions

Patients'' initial preference when presented with cosmetic appearance was for SILC. When contemporary outcome data were included, the majority chose MLC. This underlines the need to fully inform patients during the consent process and indicates that patient views of SILC may differ from the views of those introducing the technology.     

Management of choledocholithiasis in an emergency cohort undergoing laparoscopic cholecystectomy: a single-centre experience

Introduction

Minimally-invasive options for the management of choledocholithiasis in patients undergoing laparoscopic cholecystectomy include laparoscopic and endoscopic approaches. This study reviews the effectiveness of both approaches in an emergency setting.

Methods

A retrospective chart review was performed for a cohort of patients who underwent laparoscopic cholecystectomy. Outcomes assessed were duct clearance, the number of procedures performed (NPP), length of stay (LOS) and complication rate.

Results

A total of 182 patients who underwent emergency laparoscopic cholecystectomies received intervention for choledocholithiasis. The duct clearance rate was lower in the laparoscopic group, 63% versus 86% (P = 0.001). However, the median NPP was also lesser in the laparoscopic group, 1 (interquartile range (IQR) 1–2) versus 2 (IQR 2–2) (P < 0.001), as was the median LOS, 5 days (IQR 3–8) versus 7 days (IQR 6–10) (P = 0.009). Forty-eight laparoscopic endobiliary stents were attempted; stent deployment was successful in 37 patients. A larger proportion of patients with laparoscopic endobiliary stents had duct clearance by endoscopic retrograde cholangiopancreatography (ERCP) compared with those without, although this was not statistically significant (P = 0.208).

Conclusion

Laparoscopic clearance is not as effective as post-operative ERCP in an emergency cohort, but is associated with fewer procedures required and a shorter inpatient stay. Thus, laparoscopic clearance may still be an attractive option for surgeons especially where conditions are favourable during an emergency laparoscopic cholecystectomy.     

Equivalent survival following liver transplantation in patients with non-alcoholic steatohepatitis compared with patients with other liver diseases

Background

Orthotopic liver transplantation (LT) in non-alcoholic steatohepatitis (NASH) is increasing in parallel with the obesity epidemic.

Methods

This study retrospectively reviewed the clinical outcomes of LTs in NASH (n= 129) and non-NASH (n= 775) aetiologies carried out at a single centre between 1999 and 2009.

Results

Rates of 1-, 3- and 5-year overall survival in NASH (90%, 88% and 85%, respectively) were comparable with those in non-NASH (92%, 86% and 80%, respectively) patients. Mortality within 4 months of LT was twice as high in NASH as in non-NASH patients (8.5% vs. 4.2%; P= 0.04). Compared with non-NASH patients, post-LT mortality in NASH patients was more commonly caused by infectious (38% vs. 26%; P < 0.05) or cardiac (19% vs. 7%; P < 0.05) aetiologies. Five-year survival was lower in NASH patients with a high-risk phenotype (age >60 years, body mass index >30 kg/m², with hypertension and diabetes) than in NASH patients without these characteristics (72% vs. 87%; P= 0.02). Subgroup analyses revealed that 5-year overall survival in NASH was equivalent to that in Laennec''s cirrhosis (85% vs. 80%; P= 0.87), but lower than that in cirrhosis of cryptogenic aetiology (85% vs. 96%; P= 0.04).

Conclusions

Orthotopic LT in NASH was associated with increased early postoperative mortality, but 1-, 3- and 5-year overall survival rates were equivalent to those in non-NASH patients.     

A 21‐year analysis of stage I gallbladder carcinoma: is cholecystectomy alone adequate?

Objectives

Gallbladder carcinoma (GBC) is a rare disease that is often diagnosed incidentally in its early stages. Simple cholecystectomy is considered the standard treatment for stage I GBC. This study was conducted in a large cohort of patients with stage I GBC to test the hypothesis that the extent of surgery affects survival.

Methods

The National Cancer Institute''s Surveillance, Epidemiology and End Results (SEER) database was queried to identify patients in whom microscopically confirmed, localized (stage I) GBC was diagnosed between 1988 and 2008. Surgical treatment was categorized as cholecystectomy alone, cholecystectomy with lymph node dissection (C + LN) or radical cholecystectomy (RC). Age, gender, race, ethnicity, T1 sub-stage [T1a, T1b, T1NOS (T1 not otherwise specified)], radiation treatment, extent of surgery, cause of death and survival were assessed by log-rank and Cox''s regression analyses.

Results

Of 2788 patients with localized GBC, 1115 (40.0%) had pathologically confirmed T1a, T1b or T1NOS cancer. At a median follow-up of 22 months, 288 (25.8%) had died of GBC. Five-year survival rates associated with cholecystectomy, C + LN and RC were 50%, 70% and 79%, respectively (P < 0.001). Multivariate analysis showed that surgical treatment and younger age were predictive of improved disease-specific survival (P < 0.001), whereas radiation therapy portended worse survival (P = 0.013).

Conclusions

In the largest series of patients with stage I GBC to be reported, survival was significantly impacted by the extent of surgery (LN dissection and RC). Cholecystectomy alone is inadequate in stage I GBC and its use as standard treatment should be reconsidered.     

Minimal Hepatic Encephalopathy in Patients with Cirrhosis by Measuring Liver Stiffness and Hepatic Venous Pressure Gradient

Background/Aim:

Transient elastography (TE) of liver and hepatic venous pressure gradient (HVPG) allows accurate prediction of cirrhosis and its complications in patients with chronic liver disease. There is no study on prediction of minimal hepatic encephalopathy (MHE) using TE and HVPG in patients with cirrhosis.

Patients and Methods:

Consecutive cirrhotic patients who never had an episode of hepatic encephalopathy (HE) were enrolled. All patients were assessed by psychometry (number connection test (NCT-A and B), digit symbol test (DST), serial dot test (SDT), line tracing test (LTT)), critical flicker frequency test (CFF), TE by FibroScan and HVPG. MHE was diagnosed if there were two or more abnormal psychometry tests (± 2 SD controls).

Results:

150 patients with cirrhosis who underwent HVPG were screened; 91 patients (61%, age 44.0 ± 11.4 years, M:F:75:16, Child''s A:B:C 18:54:19) met the inclusion criteria. Fifty three (58%) patients had MHE (Child A (7/18, 39%), Child B (32/54, 59%) and Child C (14/19, 74%)). There was no significant difference between alanine aminotranferease (ALT), aspartate aminotransferase (AST) and total bilirubin level in patients with MHE versus non MHE. Patients with MHE had significantly lower CFF than non MHE patients (38.4 ± 3.0 vs. 40.2 ± 2.2 Hz, P = 0.002). TE and HVPG in patients with MHE did not significantly differ from patients with no MHE (30.9 ± 17.2 vs. 29.8 ± 18.2 KPas, P = 0.78; and 13.6 ± 2.7 vs. 13.6 ± 3.2 mmHg, P = 0.90, respectively).There was significant correlation of TE with Child''s score (0.25, P = 0.01), MELD (0.40, P = 0.001) and HVPG (0.72, P = 0.001) while no correlation with psychometric tests, CFF and MHE.

Conclusion:

TE by FibroScan and HVPG cannot predict minimal hepatic encephalopathy in patients with cirrhosis.     

Index admission laparoscopic cholecystectomy for patients with acute biliary symptoms: results from a specialist centre

Background:

Index admission laparoscopic cholecystectomy (ALC) is the treatment of choice for patients admitted with biliary symptoms but is performed in less than 15% of these admissions. We analysed our results for ALC within a tertiary hepatobiliary centre.

Methods:

Data from all cholecystectomies carried out under the care of the two senior authors from 1998 to 2008 were prospectively collected and interrogated.

Results:

1710 patients underwent cholecystectomy of which 439 (26%) were ALC. Pateints operated on acutely did not have a significantly different complication rate (P= 0.279; 4% vs.3%). Factors predicting complications were abnormal alkaline phosphatase (ALP) (P= 0.037), dilated common bile duct (CBD) (P= 0.026), cholangitis (P= 0.040) and absence of on table cholangiography (OTC) (P= 0.011). There were no bile duct injuries. Patients undergoing ALC had a higher rate of conversion to an open procedure (P < 0.001:10% vs.3%). The proportion of complicated disease was higher in the ALC group (P < 0.001; 70% vs.31%). Only complicated disease (P= 0.006), absence of OTC (P < 0.001) and age greater than 65 years (P < 0.001) were predictive of conversion on multivariate analysis.

Conclusions:

Laparoscopic cholecystectomy can be performed safely in patients with acute biliary symptoms and should be considered the gold standard for management of these patients thus avoiding avoidable readmissions and life-threatening complications. A higher conversion rate to an open procedure must be accepted when treating more complicated disease. It is the severity of disease rather than timing of surgery which most probably predicts complications and conversions.     

Survival analysis of high-intensity focused ultrasound ablation in patients with small hepatocellular carcinoma

Background

High-intensity focused ultrasound (HIFU) ablation is a non-invasive treatment for hepatocellular carcinoma (HCC). At present, data on the treatment''s long-term outcome are limited. This study analysed the survival outcome of HIFU ablation for HCCs smaller than 3 cm.

Patients and methods

Forty-seven patients with HCCs smaller than 3 cm received HIFU treatment between October 2006 and September 2010. Fifty-nine patients who received percutaneous radiofrequency ablation (RFA) were selected for comparison. The two groups of patients were compared in terms of pre-operative variables and survival.

Results

More patients in the HIFU group patients had Child–Pugh B cirrhosis (34% versus 8.5%; P = 0.001). The 1- and 3-year overall survival rates of patients whose tumours were completely ablated in the HIFU group compared with the RFA group were 97.4% versus 94.6% and 81.2% versus 79.8%, respectively (P = 0.530). The corresponding 1- and 3-year disease-free survival rates were 63.6% versus 62.4% and 25.9% versus 34.1% (P = 0.683).

Conclusions

HIFU ablation is a safe and effective method for small HCCs. It can achieve survival outcomes comparable to those of percutaneous RFA and thus serves as a good alternative ablation treatment for patients with cirrhosis.     

Preoperative body composition is influenced by the stage of operable pancreatic adenocarcinoma but does not predict survival after Whipple's procedure

Objectives:

Cachexia is common in pancreatic cancer and may have an influence on longterm survival but few studies have investigated this in patients with operable tumours. Therefore, this study was carried out to document body composition status in patients with pancreatic adenocarcinoma (PCa) presenting for a Whipple''s procedure (WP) and to relate the findings to histopathology and longterm survival.

Methods:

Body composition was measured 1 day before a WP for ductal PCa in 36 patients (15 men, 21 women) aged 41–81 years. Results for total body nitrogen (TBN), nitrogen index (NI), total body water (TBW), fat mass (FM) and total body potassium (TBK) were compared with results in 73 age- and sex-matched controls. Patients'' survival and details from histopathology synoptic reports were documented.

Results:

Patients undergoing WPs had low TBK values (P < 0.001) and females had lower body fat (P= 0.007) compared with controls. Five of 36 presented with significant protein deficiency, but this was not associated with a prolonged length of stay or reduced survival. The 12 patients who had involved surgical margins had larger tumours and reduced weight (P= 0.015), FM (P= 0.001), TBN (P= 0.045), TBK (P= 0.014) and survival (P= 0.036). However, multivariate Cox''s regression analysis only included FM along with vascular invasion and margin status as independent predictors of survival.

Conclusions:

PCa patients undergoing a WP have reduced body fat and TBK compared with community controls while those with stage III tumours had greater deficits of fat, TBK and protein stores. However, preoperative body composition was a poor predictor of postoperative survival after pathological data were considered.     

Clinical outcomes of a percutaneous cholecystostomy for acute cholecystitis: a multicentre analysis

Background

The aim of this study was to review a series of consecutive percutaneous cholecystostomies (PC) to analyse the clinical outcomes.

Methods

All patients who underwent a PC between 2000 and 2010 were reviewed retrospectively for indications, complications, and short- and long-term outcomes.

Results

Fifty-three patients underwent a PC with a median age was 74 years (range 14–93). 92.4% (n = 49) of patients were American Society of Anesthesiologists (ASA) III and IV. 82% (43/53) had ultrasound-guided drainage whereas 18% (10/53) had computed tomography (CT)-guided drainage. 71.6% (n = 38) of PC''s employed a transhepatic route and 28.4% (n = 15) transabdominal route. 13% (7/53) of patients developed complications including bile leaks (n = 5), haemorrhage (n = 1) and a duodenal fistula (n = 1). All bile leaks were noted with transabdominal access (5 versus 0, P = 0.001). 18/53 of patients underwent a cholecystectomy of 4/18 was done on the index admission. 6/18 cholecystectomies (33%) underwent a laparoscopic cholecystectomy and the remaining required conversion to an open cholecystectomy (67%). 13/53 (22%) patients were readmitted with recurrent cholecystitis during follow-up of which 7 (54%) had a repeated PC. 12/53 patients died on the index admission. The overall 1-year mortality was 37.7% (20/53).

Conclusions

Only a small fraction of patients undergoing a PC proceed to a cholecystectomy with a high risk of conversion to an open procedure. A quarter of patients presented with recurrent cholecystitis during follow-up. The mortality rate is high during the index admission from sepsis and within the 1 year of follow-up from other causes.     

Differences between bipolar compression and ultrasonic devices for parenchymal transection during laparoscopic liver resection

Objectives

In laparoscopic liver resection, multiple options for parenchymal transection techniques exist; however, none have emerged as superior. The aim of this study was to compare operative characteristics and outcomes between bipolar compression and ultrasonic devices used for parenchymal transection during laparoscopic liver resection.

Methods

A review of a prospective hepatopancreatobiliary database from December 2002 to August 2009 identified 54 patients who underwent laparoscopic liver resection with parenchymal division using either a bipolar compression (n = 35) or an ultrasonic (n = 19) device. Operative data, histology and 90-day complication rates were compared between the groups using analysis of variance (anova) and Pearson''s chi-squared test.

Results

The two groups did not differ significantly in terms of age, body mass index, parenchymal steatosis/inflammation or number of segments resected. A shorter time of parenchymal transection was noted for the bipolar compression device (median: 35 min; range: 20–65 min) vs. the ultrasonic device (median: 55 min; range: 29–75 min) (P < 0.001). Median total operative time was also shorter using the bipolar compression device (130 min) than the ultrasonic device (180 min) (P = 0.050). No significant differences between device groups were noted for estimated blood loss, complications of any type or liver-specific complications.

Conclusions

Bipolar compression devices may offer advantages over ultrasonic devices in terms of decreased transection time and total operative time. No differences in postoperative complications in laparoscopic liver resection emerged between patients operated using the devices.     

Alterations in colonic transit time after laparoscopic versus open cholecystectomy: a clinical study

Purpose

Postoperative enteral paresis constitutes a common problem for surgeons around the world. Evidence by many authors suggests that colonic inertia constitutes a major component of postoperative enteral paresis. This study aims at comparing the effect of laparoscopic versus open cholecystectomy on colonic transit time in humans.

Materials and methods

In this study, were included a total of 29 patients suffering from cholelithiasis, divided into two groups, a laparoscopic cholecystectomy and an open cholecystectomy group. All patients ingested one capsule containing 24 radiopaque markers on the day of the operation, and plain abdominal films were obtained on the 3rd postoperative day. The number of remaining markers was counted, and the percentage of rejected markers was calculated. For the statistical analysis, SPSS for windows version 12 was used.

Results and discussion

The study’s results show a significant difference in postoperative colonic motility, in favor of the laparoscopic cholecystectomy group (P = 0,001). Causative interpretation of these results is difficult, mainly due to the multifactorial nature of postoperative colonic hypomotility.

Conclusion

The present study suggests an advantage of laparoscopic cholecystectomy, as far as the duration of postoperative colonic paresis is concerned.

     

Robotic versus laparoscopic resection of liver tumours

Background

There are scant data in the literature regarding the role of robotic liver surgery. The aim of the present study was to develop techniques for robotic liver tumour resection and to draw a comparison with laparoscopic resection.

Methods

Over a 1-year period, nine patients underwent robotic resection of peripherally located malignant lesions measuring <5 cm. These patients were compared prospectively with 23 patients who underwent laparoscopic resection of similar tumours at the same institution. Statistical analyses were performed using Student''s t-test, χ²-test and Kaplan–Meier survival. All data are expressed as mean ± SEM.

Results

The groups were similar with regards to age, gender and tumour type (P = NS). Tumour size was similar in both groups (robotic −3.2 ± 1.3 cm vs. laparoscopic −2.9 ± 1.3 cm, P = 0.6). Skin-to-skin operative time was 259 ± 28 min in the robotic vs. 234 ± 17 min in the laparoscopic group (P = 0.4). There was no difference between the two groups regarding estimated blood loss (EBL) and resection margin status. Conversion to an open operation was only necessary in one patient in the robotic group. Complications were observed in one patient in the robotic and four patients in the laparoscopic groups. The patients were followed up for a mean of 14 months and disease-free survival (DFS) was equivalent in both groups (P = 0.6).

Conclusion

The results of this initial study suggest that, for selected liver lesions, a robotic approach provides similar peri-operative outcomes compared with laparoscopic liver resection (LLR).     

Patient-Reported Quality of Pain Treatment and Use of Interpreters in Spanish-Speaking Patients Hospitalized for Obstetric and Gynecological Care

BACKGROUND

Assessment and treatment of pain are based largely on patient’s self reports. Patients with limited English proficiency (LEP) may have difficulties communicating their pain symptoms in the presence of language barriers.

OBJECTIVE

To determine whether interpreter use was associated with quality of acute pain treatment among Latina patients with limited English proficiency.

DESIGN

Secondary analysis of two cross-sectional surveys.

PARTICIPANTS

One hundred and eighty-five Latino female patients hospitalized for obstetric and gynecological care who required interpreter services. Patients were classified into two groups according to interpreter availability (''Always'' and ''Not Always'' available).

MAIN MEASURES

Quality of pain treatment was measured by patient report of 1) overall level of pain control during hospitalization; 2) timeliness of pain treatment; and 3) perceived provider helpfulness to treat pain.

KEY RESULTS

Patients who always received interpreters were more likely to report higher levels of pain control (P = 0.02), timely pain treatment (P = 0.02), and greater perceived provider helpfulness to treat their pain (P = 0.005), compared with patients who not always received interpreters.

CONCLUSION

Use of interpreters by LEP patients was associated with better patient reports on quality of pain treatment, and may also improve clinical interactions related to pain.KEY WORDS: interpreters, limited English proficiency, Latinos/Latinas, pain, pain treatment     

Does pre‐operative chemoradiation for initially unresectable or borderline resectable pancreatic adenocarcinoma increase post‐operative morbidity? A case‐matched analysis

Background

Neoadjuvant chemoradiation therapy for locally unresectable and borderline resectable pancreatic cancer may allow some patients to a undergo a resection, but whether or not this increases post-operative morbidity remains unclear.

Methods

The post-operative morbidity of 29 patients with initially locally unresectable/borderline pancreatic cancer who underwent a resection were compared with 29 patients with initially resectable tumours matched for age, gender, the presence of comorbidities (yes/no), American Society of Anesthesiology (ASA) score, tumour location (head/body-tail), procedure (pancreaticoduodenectomy/distal pancreatectomy) and vascular resection (yes /no). Wilcoxon''s signed ranks test was used for continuous variables and McNemar''s chi-square test for categorical variables.

Results

Compared with patients with initially resectable tumours, patients who underwent a resection after pre-operative chemoradiation therapy had similar rates of overall post-operative complications (55% versus 41%, P = 0.42), major complications (21% versus 21%, P = 1), pancreatic leaks and fistulae (7% versus 10%, P = 1) and mortality (0% versus 1.7%, P = 1).

Conclusion

Although some previous studies have suggested differences in post-operative morbidity after chemoradiation, our case-matched analysis did not find statistical differences in surgical morbidity and mortality associated with pre-operative chemoradiation therapy.     

The long-term effect of bile duct injuries on health-related quality of life: a meta-analysis

Background

The reported effects of biliary injury on health-related quality of life (HRQOL) have varied widely. Meta-analysis methodology was applied to examine the collective findings of the long-term effect of bile duct injury (BDI) on HRQOL.

Methods

A comprehensive literature search was conducted in March, 2012. Because the HRQOL surveys differed among reports, BDI and uncomplicated laparoscopic cholecystectomy (LC) groups'' HRQOL scores were expressed as effect sizes (ES) in relation to a common, general population, standard. A negative ES indicated a reduced HRQOL, with a substantive reduction defined as an ES ≤ −0.50. Weighted logistic regression tested the effects of BDI (versus LC) and follow-up time on whether physical and mental HRQOL were substantively reduced.

Results

Data were abstracted from six publications, which encompass all reports of HRQOL after BDI in the current, peer-reviewed literature. The analytic database comprised 90 ES computations representing 831 patients and 11 unique study groups (six BDI and five LC). After controlling for follow-up time (P ≤ 0.001), BDI patients were more likely to have reduced long-term mental [odds ratio (OR) = 38.42, 95% confidence interval (CI) = 19.14–77.10; P < 0.001] but not physical (P = 0.993) HRQOL compared with LC patients.

Discussion

This meta-analysis of findings from six peer-review reports indicates that, in comparison to LC, there is a long-term detrimental effect of BDI on mental HRQOL.     

Are we getting the critical view? A prospective study of photographic documentation during laparoscopic cholecystectomy

Background

At laparoscopic cholecystectomy, most surgeons have adopted the operative approach where the ‘critical view of safety’ (CVS) is achieved prior to dividing the cystic duct and artery. This prospective study evaluated whether an adequate critical view was achieved by scoring standardized intra-operative photographic views and whether there were other factors that might impact on the ability to obtain an adequate critical view.

Methods

One hundred consecutive patients undergoing a laparoscopic cholecystectomy were studied. At each operation, two photographs were taken. Two independent experienced hepatobiliary surgeons scored the photographs on whether a critical view of safety was achieved. Inter-observer agreement was calculated using the weighted kappa coefficient. The Cochran–Mantel–Haenszel test was used to analyse the scores with potential confounding clinical factors.

Results

The kappa coefficient for adequate display of the cystic duct and artery was 0.49; 95% confidence interval (CI) 0.33 to 0.64; P = 0.001. No bias was detected in the overall scorings between the two observers (χ² 1.33; P = 0.312). Other clinical factors including surgeon seniority did not alter the outcome [odds ratio (OR) 0.902; 95% confidence interval 0.622 to 1.264].

Conclusion

Heightened awareness of the CVS through mandatory documentation may improve both trainee and surgeon technique.     

Timing of laparoscopic cholecystectomy for subacute calculous cholecystitis: early or interval — a prospective study

Background/Purpose

The aim of this prospective study was to evaluate the safety and feasibility of early laparoscopic cholecystectomy for subacute cholecystitis and to compare it with interval laparoscopic cholecystectomy.

Methods

The study was performed in 74 patients who had been diagnosed with subacute cholecystitis between January 2000 and June 2005. The patients were divided into two groups. The early laparoscopic cholecystectomy group was composed of 31 patients who underwent laparoscopic cholecystectomy 24?h after admission to the hospital. The interval laparoscopic cholecystectomy group was composed of 43 patients who underwent laparoscopic cholecystectomy 8–12 weeks after medical treatment.

Results

There was no significant difference between the conversion rate, intraoperative bleeding, need for intraoperative cholangiography, minor bile duct injury, and postoperative complications in the two groups. Eleven patients in the interval group underwent urgent laparoscopic cholecystectomy or additional procedures because of recurrent cholecystitis, choledocholithiasis, or biliary pancreatitis. The early group had a significantly shorter total hospital stay (P = 0.031), lower cost of treatment (P = 0.042), and less difficulty with Calot's triangle dissection (P = 0.008).

Conclusions

Early laparoscopic cholecystectomy can be done without hesitation in patients with subacute cholecystitis, in the light of obstacles observed in the interval group, such as dissection difficulty, lack of success in “cooling down”, and additional problems such as choledocholithiasis and biliary pancreatitis.     

Minimally invasive versus the conventional open surgical approach of a radical cholecystectomy for gallbladder cancer: a retrospective comparative study

Background

Laparoscopic surgery has traditionally been contraindicated for the management of gall bladder cancer (GBC). This study was undertaken to determine the safety and feasibility of a laparoscopic radical cholecystectomy (LRC) for GBC and compare it with an open radical cholecystectomy (ORC).

Methods

Retrospective analysis of primary GBC patients (with limited liver infiltration) and incidental GBC (IGBC) patients (detected after a laparoscopic cholecystectomy) who underwent LRC between June 2011 and October 2013. Patients who fulfilled the study criteria and underwent ORC during the same period formed the control group.

Results

During the study period, 147 patients with GBC underwent a radical cholecystectomy. Of these, 24 patients (primary GBC– 20, IGBC – 4) who underwent a LRC formed the study group (Group A). Of the remaining 123 patients who underwent ORC, 46 matched patients formed the control group (Group B). The median operating time was higher in Group A (270 versus 240 mins, P = 0.021) and the median blood loss (ml) was lower (200 versus 275 ml, P = 0.034). The post-operative morbidity and mortality were similar (P = 1.0). The pathological stage of the tumour in Group A was T_1b (n = 1), T₂ (n = 11) and T₃ (n = 8), respectively. The median lymph node yield was 10 (4–31) and was comparable between the two groups (P = 0.642). During a median follow-up of 18 (6–34) months, 1 patient in Group A and 3 in Group B developed recurrence. No patient developed a recurrence at a port site.

Conclusion

LRC is safe and feasible in selected patients with GBC, and the results were comparable to ORC in this retrospective comparison.
