Safety of laparoscopic approach for acute cholecystitis: retrospective study of 609 cases

Clinical Predictive Score for Cholecystectomy Wound Infection: WEBAC Score

BACKGROUND

Most common surgical complications in cholecystectomy are surgical site infections (SSIs). SSIs have many factors, including patient, surgical, and disease factors. This study aims to find the factors which relate to SSIs 30 days after cholecystectomy and contribute to the scoring system to predict SSIs.

METHODS AND MATERIAL

The data of patients who underwent cholecystectomy from January 2015 to December 2019 were retrospectively collected from a prospectively collected infectious control registry. The SSI was defined following the CDC criteria and assessed before discharge and at a 1-month follow-up. Variables that were independently predictive of the increased SSIs were included in the risk score.

RESULTS

The patients who underwent cholecystectomy were 949, which were divided into 28 patients who had SSIs and 921 who had no SSIs. The rate of SSIs was 3%. The factors related to SSI in cholecystectomy were age ≥ 60 years (p = 0.045), history of smoking (p = 0.004), retrieval bag use (p = 0.005), preoperative ERCP (p = 0.02), and wound class III and IV (p = 0.007). Risk assessment was using five variables (WEBAC): (1) wound classifications, (2) preoperative ERCP, (3) retrieval plastic bag use, (4) aged ≥ 60 years, and (5) history of smoking (cigarette). If patients were aged ≥ 60 years and had a history of smoking, no plastic bag use, preoperative ERCP, or wound class III or IV, these parameters would all be scored 1 each. The WEBAC score revealed the probability of SSIs in cholecystectomy wounds.

CONCLUSION

The WEBAC score represents a convenient and simple tool to predict the probability of SSI in the patients who underwent cholecystectomy and might increase the surgeons' awareness of postoperative SSI.

Novel Application of Hydrodissection in Laparoscopic Cholecystectomy for Gangrenous Gallbladders

INTRODUCTION

Laparoscopic cholecystectomy (LC) for gangrenous gallbladders (GGBs) can be challenging and represent a significant number of LC cases, necessitating more efficacious surgical techniques. Currently, the standard treatment for GGBs is blunt dissection which can have high iatrogenic complication rates. To our knowledge, this is the first large retrospective study conducted on the novel application of hydrodissection (HD) in LCs for GGBs.

METHODS

In this retrospective study of 386 LCs, data were collected for patient demographics, medical comorbidities, operating time (OT), anesthesia time (AT), length of stay (LOS), estimated blood loss, conversion to open procedures, 30-day readmissions, and mortality. Patients were categorized into four groups: (1) Vyas employing HD for GGBs (VHG), (2) non-Vyas group of five surgeons not employing HD for GGBs (NVG), (3) Vyas treating non-GGBs, and (4) non-Vyas group of five surgeons treating non-GGBs. Control groups were age-matched and sex-matched. Statistical analysis used descriptive statistics, Mann-Whitney U testing, and chi-squared testing (α = 0.05).

RESULTS

This study demonstrated significantly decreased (P < 0.05) OT (P = 0.001), AT (P < 0.001), LOS (P = 0.015), and conversion to open procedures (P = 0.047) between the VHG and NVG groups, with HD reducing OT by 35.5% compared to blunt dissection. This study did not demonstrate significantly decreased (P > 0.05) estimated blood loss (P = 0.185) and 30-day readmissions (P = 0.531) between the VHG and NVG groups, but they were trending toward significant. There were no mortalities in this study.

CONCLUSIONS

HD is associated with improved surgical outcomes of LCs for GGBs demonstrated by reduced OT, AT, LOS, and conversion to open procedures. Further multi-institutional studies are needed to validate HD implementation and further dissemination.

Novel Use of Intraoperative Fluoroscopy in an Era of ICG for Complex Laparoscopic Cholecystectomy

Background  Laparoscopic cholecystectomy (LC) is increasingly being used as a first-line treatment for acute cholecystitis. Bile duct injury (BDI) remains the most feared complication of the minimally invasive approach specially in cases with an inflamed calots triangle. While use of indocyanine dye (ICG) to delineate biliary anatomy serves to reduce BDI, the high cost of the technology prohibits its use in the developing world. We propose a novel use of common bile duct (CBD) stenting preoperatively in cases of cholecystitis secondary to choledocholithiasis as a means of identification and safeguarding the CBD.

Methods  A retrospective review was conducted on 22 patients of Grade 2 or Grade 3 cholecystitis who underwent an early LC at our institution. All patients were stented preoperatively and the stent was used for a much-needed tactile feedback during dissection. A c-arm with intraoperative fluoroscopy was used to identify the CBD prior to clipping of the cystic duct.

Results  The gall bladder was gangrenous in all the cases while two cases had evidence of end organ damage. This innovative use of CBD stenting allowed us to correctly delineate biliary anatomy in all of the cases and we report no instances of BDI despite a severely inflamed local environment.

Conclusion  This technique can become a standard of care in all teaching institutions in developing countries further enhancing the safety of cholecystectomy in gangrenous cholecystitis with a distorted biliary anatomy.

Use of retrieval bag in the prevention of wound infection in elective laparoscopic cholecystectomy: is it evidence-based? A meta-analysis

Background

Surgical site infections complicate elective laparoscopic cholecystectomies in 2,4-3,2% of cases. During the operation the gallbladder is commonly extracted with a retrieval bag. We conducted a meta-analysis to clarify whether its use plays a role in preventing infections.

Methods

Inclusion criteria: elective cholecystectomy, details about the gallbladder extraction and data about local or systemic infection rate. Exclusion criteria: cholecystitis, jaundice, concurrent antibiotic therapy, immunosuppression, cancer. A comprehensive literature search of PubMed, Cochrane Library and MEDLINE databases was carried out independently by two researchers, according to the PRISMA guidelines and applying the GRADE approach. Terms used were (“gallbladder”AND(“speciment”OR“extraction”OR“extract”))OR(“gallbladder”OR“cholecystectomy”)AND(“bag”OR“retrieval|”OR|“endobag”OR“endocatch”).

Results

The comprehensive literature revealed 279 articles. The eligible studies were 2 randomized trials and a multicentre prospective study. Wound infections were documented in 14 on 334 (4,2%) patients operated using a retrieval bag versus 16 on 271 (5,9%) patients operated without the use of a retrieval bag. The statistical analysis revealed a risk ratio (RR) of 0.82 (0.41–1.63 95% CI). Concerning sensitivity analysis the estimated pooled RR ranged from 0.72 to 0.96, both not statistically significant. Harbord test did not reveal the occurrence of small-study effect (p = 0.892) and the funnel-plot showed no noteworthy pattern.

Conclusions

The results of this review highlight the paucity of well-designed large studies and despite limitations related to the low level of evidence, our meta-analysis showed no significant benefit of retrieval bags in reducing the infection rate after elective laparoscopic cholecystectomy. In absence of acute cholecystitis, accidental intraoperative gallbladder perforation or suspected carcinoma their use, to date, may not be mandatory, so that, further studies focusing on complex cases are needed.

Is Single-incision Laparoscopic Cholecystectomy Feasible for Acute Cholecystitis? A Consecutive Study of 60 Cases

The feasibility of single-incision laparoscopic cholecystectomy (SIL-C) for patients with acute cholecystitis were evaluated based on the timing of operation after onset of symptoms. Sixty patients with acute cholecystitis who underwent SIL-C were divided into 2 groups according to the timing of operation: group E included 23 patients who underwent SIL-C within 72 hours, and group O included 37 patients who underwent SIL-C later. There were no statistical differences between group E and group O in clinicopathologic characteristics. Group E demonstrated significantly shorter operating time and less blood loss than group O. Although the incidences of additional port(s) requirements were not significantly different, 8 patients in group O required open conversion, indicating significantly higher rate. As group E demonstrated favorable surgical outcomes compared with group O, SIL-C for acute cholecystitis seems to be a feasible therapeutic procedure when performed within 72 hours as updated Tokyo Guidelines recommended.

Early laparoscopic cholecystectomy is superior to delayed acute cholecystitis: a meta-analysis of case-control studies

BACKGROUND

Since the advent of laparoscopic cholecystectomy (LC) there has been continued debate regarding the management of acute cholecystitis with either early or delayed LC. Nearly all studies have demonstrated that early LC has a significantly shorter total length of hospital stay compared with delayed LC. Although previous randomized controlled trials and meta-analysis have shown clinical outcomes to favour early surgery, clinical practice continues to vary significantly worldwide. In addition, there is much confusion in the optimal timing for early LC with definitions of early varying from 72 h to 7 days. There have been numerous case-control studies investigating the timing of LC in acute cholecystitis. The aim of this paper is to pool the results from all case-control studies to investigate outcomes including mortality rates, complication rates, length of hospital stay and conversion rates to open procedures.

METHODS

A search of electronic databases was performed for case-control studies published between 1985-February 2015.

RESULTS

Results from 77 case-control studies showed statistically significant reductions in mortality, complications, bile duct leaks, bile duct injuries, wound infections, conversion rates, length of hospital stay and blood loss associated with early LC. Although LC within the 72-h window is optimal, patients operated after this window still benefit from early surgery compared to delayed surgery. The duration of symptoms in acute cholecystitis should not influence the surgeons' willingness to operate acutely.

CONCLUSIONS

Early LC is clearly superior to delayed LC in acute cholecystitis. The most recent evidence-based practice strongly suggests that early LC should be standard of care in the management of acute cholecystitis.

Is emergent laparoscopic cholecystectomy for acute cholecystitis safe in a low volume resource poor setting?

BACKGROUND

The outcomes of emergent laparoscopic cholecystectomy (LC) for acute cholecystitis have not been documented in the low-volume, resource-poor Caribbean setting.

SETTINGS AND DESIGN

This study was carried out in a low-resource setting across three islands in the Anglophone Caribbean.

METHODS AND MATERIALS

The records of all consecutive patients who had emergency LC for acute cholecystitis over 82 months were examined. The data were extracted and analysed using SPSS version 14.

RESULTS

There were 74 patients with acute cholecystitis at a mean age of 45 (SD 11.8) years. The mean duration of operation was 99 (SD 45) min. There were 3 (4.1%) conversions and 6 (8.1%) complications. No bile duct injuries or deaths were recorded. There was more morbidity in patients with complicated disease, longer mean operation times and longer mean intervals between admission and operation.

CONCLUSIONS

Emergent LC for acute cholecystitis is effective and safe in a low-volume setting in the Caribbean. However, the operations are technically demanding and should be performed by trained laparoscopic surgeons.

Laparoscopy in the acute abdomen

Laparoscopy has become a routine procedure in the management of acute abdominal disease and can be considered both an excellent therapeutic and additional diagnostic tool in selected cases. However, a high level of expertise in laparoscopic and emergency surgery is required. Hemodynamic instability, huge abdominal distension, fecal peritonitis and perforated cancer are relative contraindications for the laparoscopic approach. In recent years, abdominal emergencies have increasingly been managed successfully by laparoscopy. In acute appendicitis, acute cholecystitis and perforated peptic ulcer, randomized controlled trials have proven that the laparoscopic approach is as safe and as effective as open surgery, with fewer complications and a quicker postoperative recovery. Other indications such as blunt and penetrating trauma to the abdomen, small bowel occlusion and perforated diverticular disease are under debate, indicating that more randomized controlled trials comparing laparoscopic and open surgery are still necessary.

Multivariate analysis of factors influencing length of hospitalization and medical costs of cholecystectomy for acute cholecystitis in Japan: a national database analysis

Little information is available on the factors influencing length of stay (LOS) in hospital and medical costs during hospitalization associated with cholecystectomy for acute cholecystitis. We determined the independent factors affecting LOS and medical costs of patients who underwent cholecystectomy for acute cholecystitis based on data from the Diagnosis Procedure Combination (DPC) database. In 2008, a total of 2176 patients with acute cholecystitis were referred for cholecystectomy to 624 hospitals in Japan. We collected patient characteristics and data on treatments for acute cholecystitis using the DPC database and identified independent factors affecting LOS and medical costs during hospitalization using multiple linear regression models. Analysis revealed that early cholecystectomy was significantly associated with a decrease in LOS, whereas longer preoperative antimicrobial therapy was significantly associated with an increase of LOS: the standardized coefficient for early cholecystectomy was -0.372 and that for preoperative antimicrobial therapy was 0.353 (P < 0.001). These procedures were also significant independent factors with regard to medical costs during hospitalization: the standardized coefficient for early cholecystectomy was -0.391 and that for preoperative antimicrobial therapy was 0.335 (P < 0.001). Early cholecystectomy significantly reduces the LOS and medical costs of cholecystectomy for acute cholecystitis, while preoperative antimicrobial therapy increases LOS and medical costs during hospitalization. These results highlight the need for health care implementations such as promotion of early cholecystectomy, appropriate use of antimicrobial drugs, and centralization of patients with cholecystectomy for acute cholecystitis in Japan.

The care processes for acute cholecystitis according to clinical practice guidelines based on the Japanese administrative database

Acute cholecystitis is one of the most frequently encountered conditions in daily practice in Japan. However, there is a shortage of detailed data about treatments that have been performed according to the clinical practice guidelines (CPGs) for acute cholecystitis. We therefore examined the management of acute cholecystitis for adherence to the appropriate CPGs using the Japanese administrative database associated with the Diagnosis Procedure Combination (DPC) system. We collected data from 6,070 patients with acute cholecystitis, examining for the application of four recommended treatments (administration of antimicrobial drugs and nonsteroidal anti-inflammatory drugs (NSAIDs) and performance of early and laparoscopic cholecystectomy). The patients were classified according to the procedures documented for each case: no gallbladder drainage (n = 4,333), gallbladder drainage without supportive care (ventilation or hemodiafiltration or the use of vasopressor) (n = 1,591) and gallbladder drainage and supportive care (n = 146). Multiple logistic regression models revealed that patients with gallbladder drainage without supportive care and those with gallbladder drainage and supportive care significantly higher received administration of antimicrobial drugs and NSAIDs, while these patients underwent less early or laparoscopic cholecystectomy than did patients without gallbladder drainage, after adjusting for potential confounding effects of the clinical variables. This study demonstrated that there were various differences with regard to the performance of recommended treatments between the levels of procedures required for acute cholecystitis. In addition, this administrative database was a feasible tool for the evaluation of care processes and will provide useful information contributing to improved quality of medical care.

Advantages of early cholecystectomy in clinical practice of a terciary care center

BACKGROUND

Despite a number of studies show the superiority of early over delayed cholecystectomy in the treatment of acute cholecystitis, there is still controversy over the time for intervention. This study aimed to assess the use of early versus delayed cholecystectomy for the treatment of acute cholecystitis in terms of complications, conversion to open surgery and mean hospital stay.

METHOD

We collected patients with acute cholecystitis treated at a referral center for a year, and retrospectively analyzed the chosen therapeutic approach, the percentage of conversion of early cholecystectomy to open surgery, appearance of surgical complications, and mean hospital stay.

RESULTS

The study included 117 patients, 44 women and 73 men, who had a mean age of 67.36+/-15.74 years. Early cholecystectomy was chosen in 31 (26.5%) and delayed cholecystectomy in 74 patients (63.2%). Of the 74 patients, 28 (37.8%) required emergency performance of delayed cholecystectomy, and 19 (25.7%) had not undergone surgery by the end of the study. While no differences were observed between early and delayed cholecystectomy in terms of surgical complications and conversion to open surgery, mean hospital stay was nevertheless significantly shorter in the early versus the delayed cholecystectomy group (8.32+/-4.98 vs 15.96+/-8.89 days).

CONCLUSION

Under the routine working conditions of a hospital that is neither specially dedicated to the surgical treatment of acute cholecystitis nor provided with specific management guidelines, early cholecystectomy can reduce the hospital stay without increase of the conversion rate or complications.

Impact of risk factors for prolonged operative time in laparoscopic cholecystectomy

OBJECTIVE

Laparoscopic cholecystectomy (LC) remains one of the most frequent surgical therapies for symptomatic gallstone disorders. Prolonged operative time is frequently associated with increased complication rates. The aim of this study was to identify the risk factors for prolonged operative times to minimize perioperative morbidity and optimize clinical management.

METHODS

A total of 677 consecutive patients underwent LC. The exclusion criteria were conversion to an open procedure, intraoperative cholangiography, and liver cirrhosis (n=81). Data were analyzed retrospectively with respect to age, sex, BMI, ASA score, previous abdominal surgery, preoperative endoscopic retrograde cholangiopancreatography, acute cholecystitis, and surgeon's experience. Univariate and multivariate analyses were performed.

RESULTS

A total of 596 patients, mean (± SD) age of 52.2 ± 16.7 years, were analyzed. In all, 29% of the patients were obese (BMI ≥ 30 kg/m); 11% had ASA III. Five percent of patients had undergone previous upper abdominal surgery. Overall, 105/596 patients had an acute cholecystitis. Residents of general surgery performed 58% of all operations. The median operative time was 80 min (range, 15-281 min). No statistical significance was found between intraoperative and postoperative complications by surgeon's experience. Statistically, independent preoperative predictors for prolonged operative time as identified through multivariate analysis were acute cholecystitis, obesity, previous upper abdominal surgery, male sex, and low degree of surgical expertise.

CONCLUSION

The risk for prolonged operative times in LC can be assessed on the basis of patients' characteristics. Assessment of these factors not only helps to optimize the individual outcome for each patient but also improves the decision process toward operative training for junior surgeons.

Surgical management of acute cholecystitis: results of a 2-year prospective multicenter survey in Belgium

BACKGROUND

Laparoscopic cholecystectomy is considered nowadays as the standard management of acute cholecystitis (AC). However, results from multicentric studies in the general surgical community are still lacking.

METHODS

A prospective multicenter survey of surgical management of AC patients was conducted over a 2-year period in Belgium. Operative features and patients' clinical outcome were recorded. The impact of independent predictive factors on the choice of surgical approach, the risk of conversion, and the occurrence of postoperative complications was studied by multivariate logistic regression analysis.

RESULTS

Fifty-three surgeons consecutively and anonymously included 1,089 patients in this prospective study. A primary open approach was chosen in 74 patients (6.8%), whereas a laparoscopic approach was the first option in 1,015 patients (93.2%). Independent predictive factors for a primary open approach were previous history of upper abdominal surgery [odds ratio (OR) 4.13, p < 0.001], patient age greater than 70 years (OR 2.41, p < 0.05), surgeon with more than 10 years' experience (OR 2.08, p = 0.005), and gangrenous cholecystitis (OR 1.71, p < 0.05). In the laparoscopy group, 116 patients (11.4%) required conversion to laparotomy. Overall, 38 patients (3.5%) presented biliary complications and 49 had other local complications (4.5%). Incidence of bile duct injury was 1.2% in the whole series, 2.7% in the open group, and 1.1% in the laparoscopy group. Sixty patients had general complications (5.5%). The overall mortality rate was 0.8%. All patients who died were in poor general condition [American Society of Anesthesiologists (ASA) III or IV].

CONCLUSIONS

Although laparoscopic cholecystectomy is currently considered as the standard treatment for acute cholecystitis, an open approach is still a valid option in more advanced disease. However, overall mortality and incidence of bile duct injury remain high.

[Laparoscopic cholecystectomy of acute cholecystitis]

INTRODUCTION

Laparoscopic cholecystectomy is a method of choice for surgical treatment of diseases of gallbladder. Although most surgeons today use laparoscopic cholecystectomy in treatment of severe acute cholecystitis, most surgeons still consider acute cholecystitis a relevant contraindication for laparoscopic cholecystectomy because of "confused" anatomy and "severe" pathology. Aim of the study was to analyze laparoscopic cholecystectomy outcomes in treatment of acute cholecystitis.

MATERIAL AND METHODS

A prospective analysis included 78 patients operated for acute calculose cholecystitis from Jan 2007 to Dec 2008. We analyzed clinical characteristics of the course of disease, associated diseases, duration of operation, operative and postoperative complications, reasons for conversion into open cholecystectomy.

RESULTS

The study indicated a low percentage of operative and postoperative complications, short stay in hospital, quick recovery and saving in treatment. The length of preoperative and postoperative hospitalization was 1.4 +/- 0.5 days and 2.5 +/- 1.6 days, respectively. 25 (32%) patients were operated within 72 hours from the onset of symptoms,some operative difficulties were present in 56 (71%) patients, light identification of artery and ductus cysticus in 30 (38.50%) patients, intraoperative lesion of ductus choledohus in 1 (1.3%); in 6 (7.7%) patients conversion into open cholecystectomy was done, the average duration of laparascopic cholecystectomy was 58.1 +/- 26.2 min. There were no lethal outcomes.

CONCLUSION

Laparoscopic cholecystectomy is an efficient and reliable operative procedure in treatment of acute cholecystitis. It is much easier to select patients for laparoscopic cholecystectomy when preoperative risk factors predicting difficulties during the operation are known. An early conversion into open cholecystectomy is a rational choice of any surgeon when anatomy is not clear and in cases of advanced inflammatory process in order to decrease operative and postoperative morbidity.

Two rare cases of intrahepatic subcapsular hematoma after laparoscopic cholecystectomy

The appearance of subcapsular liver hematoma after a laparoscopic cholecystectomy (LC) is an infrequent complication and seldom studied. Some cases have been connected to ketorolac given during surgery and after surgery. Other described causes are : hemangiomas or small iatrogenic lesions that could be aggravated by administration of ketorolac. Coagulation dysfunction like circulating heparin as seen in hemathological diseases is cause of bleeding after aggressive procedures. We describe two cases of subcapsular liver hematoma after LC, both of them have been given intravenous ketorolac and one of them had multiple myeloma. We discuss the causes and treatment of it.

Laparoscopic cholecystectomy: analysis of 619 consecutive cases in a Caribbean setting

INTRODUCTION

Laparoscopic cholecystectomy has become the gold standard in the definitive treatment of symptomatic gall bladder disease. It boasts superior morbidity and mortality and lower complication rates than open approaches.

AIM

This study outlines the experiences associated with 619 laparoscopic cholecystectomies performed in Trinidad.

METHODS

The records of 619 consecutive patients who underwent the procedure were reviewed. All cases were either performed or supervised by the senior author. The population comprised 511 females and 108 males. The average age was 48.5 years.

RESULTS

The commonest indications for surgery were symptomatic cholelithiasis (380 cases) and acute cholecystitis (111 cases). The mean operating time was 34 minutes. The mean length of stay on the ward was 17.45 hours. Mortality was zero. Only 4 cases were converted to open procedures. The commonest postoperative complication was wound-infection.

CONCLUSION

In summary, this study demonstrates that laparoscopic cholecystectomy can be performed safely in a Third World setting with results comparable to those internationally.

Laparoscopic cholecystectomy in patients with empyematous cholecystitis: an outcome analysis

BACKGROUND

Laparoscopic cholecystectomy (LC), the procedure of choice for elective cholelithiasis, is now also used in the management of acute cholecystitis. Empyema of the gallbladder is unexpectedly encountered in a proportion of these patients. This paper describes our experience with LC in the treatment of patients with empyema of the gallbladder.

METHODS

From May 1992 to July 2007, 315 patients with a clinical diagnosis of acute cholecystitis underwent LC. Operative and histopathology reports were used to identify patients with empyema of the gallbladder, to which retrospective chart reviews were applied. Factors associated with conversion and complications were assessed to determine their predictive power.

RESULTS

Being male and having high levels of aspartate transaminase (AST), alanine transaminase (ALT), and white blood cells significantly influenced the prediction of empyema. The conversion rate was significantly higher for empyema and acute cholecystitis, but the complication rate did not differ significantly between these conditions. Previous abdominal surgery was an independent risk factor for conversion and complications. Also, temperature >37.5°C, AST >60 IU/l, and ALT >60 IU/l were associated with higher conversion rates. The hospital stay was longer in patients with empyema, while the operation time did not differ between the two groups.

CONCLUSION

Empyema of the gallbladder can be encountered in patients with presumed acute cholecystitis. Preoperatively differentiating between simple acute cholecystitis and empyema is difficult, if not impossible. The conversion rate is expected to be higher when empyema is approached laparoscopically than for simple acute cholecystitis or symptomatic cholelithiasis.

The cost of ignoring acute cholecystectomy

INTRODUCTION

Biliary symptoms whilst awaiting elective cholecystectomy are common, resulting in hospital admission, further investigation and increased hospital costs. Immediate cholecystectomy during the first admission is safe and effective, even when performed laparoscopically, but acute laparoscopic cholecystectomy has only recently become increasingly commonplace in the UK. This study was designed to quantify this problem in our hospital and its cost implications.

PATIENTS AND METHODS

The case notes of all patients undergoing laparoscopic cholecystectomy in our hospital between January 2004 and June 2005 were examined for details of hospital admissions with biliary symptoms or complications whilst waiting for elective cholecystectomy. Additional bed occupancy and radiological investigations were recorded and these costs to the trust calculated. We compared the potential tariff income to the hospital trust for the actual management of these patients and if a policy of acute laparoscopic cholecystectomy on first admission were in place.

RESULTS

In the 18-month study period, 259 patients (202 females) underwent laparoscopic cholecystectomy. Of these, 147 presented as out-patients and only 11% required hospital admission because of biliary symptoms whilst waiting for elective surgery. There were 112 patients who initially presented acutely and were managed conservatively. Twenty-four patients were re-admitted 37 times, which utilised 231 hospital bed-days and repeat investigations costing over 40,000 pounds. There would have been a marginal increase in tariff income if a policy of acute laparoscopic cholecystectomy had been in place.

CONCLUSIONS

Adoption of a policy of acute laparoscopic cholecystectomy on the index admission would result in substantial cost savings to the trust, reduce elective cholecystectomy waiting times and increase tariff income.

Emergency laparoscopy for acute abdominal conditions: a prospective study

BACKGROUND

Currently, emergency laparoscopic surgery for acute abdominal conditions has become the favored surgical approach; therefore, we investigated the diagnostic accuracy and therapeutic efficacy of laparoscopy in acute abdominal pain in Saudi Arabian patients.

PATIENTS AND METHODS

In this prospective study, 176 patients with acute abdominal pain (113 patients with pain localized to the right iliac region [group A] and 63 patients with generalized abdominal pain [group B] underwent emergency laparoscopy between January 2002 and December 2006. We evaluated the initial clinical diagnosis, the laparoscopic diagnosis, and the outcome in these two groups of patients.

RESULTS

In group A, a definitive diagnosis was established at laparoscopy in 89% of patients, and it was therapeutic in 81.4% of the patients, and in 9 patients (8%) a conversion to laparotomy was necessary a to manage their condition. In group B, the diagnosis was accurate in 87% of patients, and it was therapeutic in 79.4% of the patients, and in 5 patients (8%) a conversion to laparotomy was necessary. There was no mortality.

CONCLUSIONS

The emergency laparoscopy is a diagnostic and therapeutic option in the majority of acute abdominal pain conditions.

Urgent cholecystectomy for acute cholecystitis in a district general hospital - is it feasible?

INTRODUCTION

Laparoscopic cholecystectomy has become the gold standard for treatment of symptomatic gall stone disease. However, its place remains controversial in the management of acute cholecystitis due to a high reported incidence of bile leaks and conversion rate. Tertiary referral centres have reported good results. We present a series of cases after the introduction of an urgent cholecystectomy pathway in a district general hospital.

PATIENTS AND METHODS

A practice of urgent cholecystectomy for acute cholecystitis was introduced by three consultant general surgeons. All prospective patients having an urgent laparoscopic cholecystectomy for acute cholecystitis, over an 8-month period were entered into a database. A dedicated ultrasound service was instituted to provide prompt diagnosis in these patients. Their demographic details, operative findings, laboratory results were recorded in a prospective database. Timing of ERCP, postoperative complications and conversion rate and hospital stay were also noted.

RESULTS

There were 64 patients in the study with a median age of 51 years (range, 21-84 years). There were 21 males and 43 females. All patients underwent laparoscopic cholecystectomy during the index admission. Eleven patients had pre-operative ERCP and 12 patients had on-table cholangiogram. There were no conversions. Postoperative ERCP was required in six patients. The median time interval between admission and operation was 3 days (range, 2-7 days). There were two bile leaks but no common bile duct injury. There were two cases of superficial wound infection. One patient required re-operation for small bowel obstruction secondary to a port site hernia.

CONCLUSIONS

Urgent laparoscopic cholecystectomy for acute cholecystitis is a feasible treatment option in a district general hospital. A safe practice can be ensured by adherence to a care pathway and a multidisciplinary, consultant-delivered service. Urgent cholecystectomy service can be provided safely in a district general hospital with outcomes comparable to previously published literature.

Does gender affect laparoscopic cholecystectomy?

The relationship between sex and outcome after laparoscopic surgery for symptomatic cholelithiasis remains unclear. The purpose of this study was to determine the influence of sex on the clinical presentation of patients with symptomatic gallstone disease and the clinical outcomes of laparoscopic cholecystectomy. The rates of conversion to open cholecystectomy, complication rates, operative times, and lengths of hospital stay were compared between the sexes. Compared with female patients, males were significantly older and more likely to have coexisting cardiovascular disease, previous upper abdominal surgery, previous hospitalization for acute cholecystitis and pancreatitis, acute cholecystitis, and suppurative cholecystitis (such as empyema), conversions, and complications. The mortality rate was nil. Analyses revealed an independent effect of sex on the prevalence of complications, even when including all of the major confounding factors in the model. In contrast, the effect of sex on conversion to open cholecystectomy was not significant when controlling for patient age. Operative time and postoperative hospital stay were significantly longer in males than in females. The tendency of male patients to have cholecystitis of greater severity should remind surgeons of the need to inform patients about the higher conversion rate among male patients, to reduce the disappointment of a large laparotomy wound or prolonged recovery period. On the other hand, there may be an increased need for surgeons to strongly advice male patients with symptomatic cholelithiasis to undergo early intervention.

Surgical outcomes of laparoscopic cholecystectomy for severe acute cholecystitis

The aim of this study was to evaluate the surgical outcomes of laparoscopic cholecystectomy (LC) in patients who were diagnosed with severe acute cholecystitis (SAC) and to clarify the useful treatment modalities of SAC. Of 112 patients who presented SAC, we selected 99 patients and divided them into 3 groups: 37 patients who underwent preoperative percutaneous transhepatic gallbladder drainage (PTGBD; group 1), 62 patients with SAC but not indicated for PTGBD (group 2), and 59 patients with acute and chronic cholecystitis (group 3). The conversion rate was 2.7% (1/37) in group 1, 6.5% (4/62) in group 2, and 1.7% (1/59) in group 3. In groups 1 and 2, the postoperative stay and operative time were longer than those in group 3 with significant difference, respectively (P<0.05). In group 2, there was correlation not only between postoperative stay and age but also between postoperative stay and ASA class (P<0.05). In group 2, there was no correlation between time to operation and operative time and also between time to operation and postoperative stay, however, there was surprisingly significant correlation between time to operation and conversion rate in SAC (P=0.018). In conclusion, PTGBD should selectively be performed in patients with severe comorbidities rather than improving surgical outcomes of LC for severe acute cholecystitis. If patients are not indicated for PTGBD, an early laparoscopic cholecystectomy is recommended because it can decrease conversion rate, although it cannot decrease operative time and postoperative stay.

[Iatrogenic biliary injuries during cholecystectomy]

AIM OF THE STUDY

To analyze our experience with biliary injuries during cholecystectomy in order to determine associated risk factors, morbidity, and results after reconstruction.

PATIENTS AND METHODS

Review of the series of patients referred to our department for biliary injury during cholecystectomy over a 9-year period. Items regarding the type of lesion, risk factors, management, morbidity, and late results were recorded.

RESULTS

Fifteen patients were referred to our department for bile duct injury during cholecystectomy between 1997 and 2005 (14 by laparoscopy and four by laparotomy; nine women and nine men). The main surgical indication was biliary colic (n=8). Three patients were operated on in an emergency setting (for acute cholecystitis). In nine patients the gallbladder wall was inflammatory. Intraoperative cholangiography was performed in nine patients, but revealed just one injury. Lateral injury to the bile duct was the most frequent type of lesion. In nine patients, the injury was detected intraoperatively and a biliary drainage was left in place; five of them had a synchronic repair and three required later reconstruction. Nine patients had a delayed identification of biliary injury; six of them required a biliodigestive anastomosis. Two patients died, three had several episodes of acute cholangitis after reconstruction and two presented incisional hernia.

CONCLUSION

An inflammatory environment is the main risk factor for biliary injury during cholecystectomy. Bile duct injury is more frequent with laparoscopic cholecystectomy but can also occur with an open approach. Intraoperative cholangiography does not prevent biliary injuries nor detect them accurately. Biliary drainage can reduce morbidity for intraoperatively detected injuries and may be a sensitive approach for the surgeon with no hepatobiliary experience. Morbidity is increased in patients with delayed identification of the injury.

Laparoscopic cholecystectomy: complications and conversions with the 3-trocar technique: a 10-year review

BACKGROUND

Traditional laparoscopic cholecystectomy (LC) includes the use of 4 trocars. The aim of this study is to show that LC can be performed safely with the 3-trocar technique, thus simplifying a very well-known technique.

METHODS

We performed a retrospective analysis of 1878 patients (male-to-female ratio was 1:3; median age of 44 y) that underwent 3-trocar LC between May 1994 and December 2004.

RESULTS

Three-trocar LC was successful in 1774 patients (94%) with a postoperative morbidity of 1.5% (0.5% of major complications), which includes 2 minor common bile duct lesions (type D according to Strasberg classification) and 1 right common iliac artery laceration. Mortality was nil. Among 249 cases of acute cholecystitis, the 3-trocar LC was successful in 172 patients (70%). The adoption of a fourth trocar was necessary in only 82 patients (4.3%). Conversion to laparotomy occurred in a total of 67 patient (3.5%), 22 of which directly from the 3-trocar technique. The median operating time of the 3-trocar LC was 40 minutes (range, 16 to 130) for chronic cholecystitis, and 80 minutes (range, 30 to 145) for acute cholecystitis. The difference in duration of the surgical procedure between the 2 groups was significant (P<0.05). Severe adhesions were more commonly the reason for conversion (P<0.05).

CONCLUSIONS

The study achieves to conclude that the 3-trocar technique can be safely performed, is not technically demanding, and yields in experienced hands a complication rate comparable with the conventional LC. Furthermore, it is less expensive and has a better cosmetic result.

Risk of pancreatitis following endoscopically placed large-bore plastic biliary stents with and without biliary sphincterotomy for management of postoperative bile leaks

BACKGROUND

Endoscopic transpapillary biliary stent placement is effective for closure of postoperative bile leaks. Large-bore stents (10 French) may transiently obstruct the adjacent pancreatic duct orifice causing acute pancreatitis. Endoscopic biliary sphincterotomy may reduce this risk, but it introduces separate risks of bleeding and perforation. The objective of this study was to compare complications after large-bore biliary stent placement (10 Fr) with and without sphincterotomy in patients with bile leaks.

METHODS

The institutional endoscopy database was queried to identify patients who had undergone endoscopic retrograde cholangiopancreatogrpahy (ERCP) for bile leak between March 1996 and August 2006. Procedural reports were reviewed for evidence of biliary sphincterotomy, cholangiographic and pancreatographic findings, transpapillary stent placement, and procedural complications. Patients with prior biliary sphincterotomy, choledochoenteric anastomosis, placement of multiple biliary stents and expandable metal biliary stents, biliary stents smaller than 10 Fr, and patients in whom a stent was not placed were excluded. The chi-square test was used for categorical variables. Probability <or= 0.05 was considered significant.

RESULTS

The rate of pancreatitis (all mild) after large-bore biliary stent placement was greater when sphincterotomy was not performed than when sphincterotomy and stent placement were both performed (13% versus 2.4%). This difference was not statistically significant. (Chi(2) = 3.41; p = 0.1). Bleeding was observed in one patient who underwent sphincterotomy and large-bore stent placement (2.4%). No perforations occurred in either group.

CONCLUSIONS

Although not statistically significant, there is a higher rate of post-ERCP pancreatitis after placement of large-bore biliary stents when sphincterotomy is not performed. The additional complications of biliary sphincterotomy did not offset the reduction in post-ERCP pancreatitis. When large-bore biliary stents are used in the treatment of bile leak, a biliary sphincterotomy may avoid pancreatitis. Randomized trials are needed to determine whether there is a significant difference in overall complication rate when large-bore stents are placed with and without biliary sphincterotomy.

The laparoscopic approach in abdominal emergencies: has the attitude changed? : A single-center review of a 15-year experience

BACKGROUND

Laparoscopy has been practiced more and more in the management of abdominal emergencies. The aim of the present work was to illustrate retrospectively the results of a case-control 5-year experience of laparoscopic versus open surgery for abdominal emergencies carried out at our institution, especially with regard to whether our attitude toward use of this procedure has changed as compared with the beginning of our laparoscopic emergency experience (1991-2002).

MATERIALS AND METHODS

From January 2002 to January 2007 a total of 670 patients underwent emergent and/or urgent laparoscopy (small bowel obstruction, 17; gastroduodenal ulcer disease, 16; biliary disease, 118; pelvic disease and non-specific abdominal pain (NSAP), 512; colonic perforations, 7) at the hands of a surgical team trained in laparoscopy

RESULTS

The conversion rate was 0.15%. Major complications ranged as high as 1.9% with no postoperative mortality. A definitive diagnosis was accomplished in 98.3% of the cases, and all such patients were treated successfully by laparoscopy.

CONCLUSIONS

We believe that laparoscopy is not an alternative to physical examination/good clinical judgment or to conventional noninvasive diagnostic methods in treating the patient with symptoms of an acute abdomen. However it must be considered an effective option in treating patients in whom these methods fail and as a challenging alternative to open surgery in the management algorithm for abdominal emergencies.

Laparoscopic cholecystectomy for severe acute cholecystitis. A meta-analysis of results

OBJECTIVE

The aim of this review was to evaluate surgical outcomes of laparoscopic cholecystectomy for gangrenous and empyematous acute cholecystitis defined as severe acute cholecystitis.

BACKGROUND

It is not known to what extent surgical outcomes of laparoscopic cholecystectomy for severe acute cholecystitis differ from those for the nonsevere acute form, making it questionable whether urgent laparoscopic cholecystectomy is the best approach even in severe acute cases.

METHODS

Literature searches were conducted to identify: (1) comparative studies which reported laparoscopic surgical outcomes separately for severe acute and nonsevere acute cholecystitis; (2) studies comparing such an approach with open cholecystectomy, subtotal laparoscopic cholecystectomy or cholecystostomy in severe acute cholecystitis. Results were pooled by standard meta-analytic techniques.

RESULTS

Seven studies with a total of 1,408 patients undergoing laparoscopic cholecystectomy were found. The risks of conversion (RR 3.2, 95% CI 2.5 to 4.2) and overall postoperative complications (RR 1.6, 95% CI 1.2-2.2) were significantly higher in severe acute cholecystitis with respect to the nonsevere acute forms. However, no difference was detected as regards to local postoperative complications. No studies comparing open cholecystectomy or cholecystostomy with urgent laparoscopy were found.

CONCLUSION

A lower feasibility of laparoscopic cholecystectomy has been found for severe cholecystitis. A lower threshold of conversion is recommended since this may allow to reduce local postoperative complications. Literature data lack valuable comparative studies with other treatment modalities, which therefore need to be investigated.

Routine early laparoscopic cholecystectomy for acute cholecystitis after conclusion of a randomized controlled trial

Background

The aim of this retrospective review was to assess the clinical outcomes of laparoscopic cholecystectomy for acute cholecystitis since the conclusion of a randomized controlled trial in 1997.

Methods

Records of all patients admitted for acute cholecystitis in whom early laparoscopic cholecystectomy was attempted between July 1997 and December 2004 were reviewed.

Results

A total of 209 patients were recruited to this study. Forty-three surgeons performed the procedures. The conversion rate increased significantly in the early period after the trial from 21 per cent to 42 per cent (39 of 92 patients) and decreased significantly to 24 per cent (13 of 54 patients) in the later period. The proportion of operations performed by higher surgical trainees increased significantly from 17 per cent in the early period to 56 per cent in the later period. This increase was associated with a fall in conversion rate without any significant increase in duration of operation or complication rate.

Conclusion

This study has demonstrated that the results achieved in a randomized trial can be translated into clinical practice by the entire surgical unit. A structured training programme with the inclusion of an experienced surgeon assisting both trainees and specialists should minimize this learning curve.

The Contribution of Acute Cholecystitis, Obesity, and Previous Abdominal Surgery on the Outcome of Laparoscopic Cholecystectomy

The aim of this study was to evaluate the impact of acute cholecystitis (AC), obesity, and previous abdominal surgery on laparoscopic cholecystectomy (LC) outcomes. Records of 1940 patients undergoing LC in 1992 and 2004 were reviewed in order to assess the independent and joint effects of the above risk factors on conversion, morbidity, operation time, and hospital stay. In multivariate regression analysis, adjusting for sex and age, AC alone and in combination with obesity or previous abdominal surgery increased the risk of conversion and complications and was associated with prolonged operation time and hospital stay compared with the patients without any of the risk factors (reference group). The independent and joint effects of obesity and previous abdominal surgery were significant only on operation time. On the contrary, previous upper abdominal surgery alone and in combination with AC was associated with 3- and 17-fold relative odds of conversion, respectively. The combined presence of AC, obesity, and previous abdominal surgery yielded an odds ratio for conversion of 7.5 and for complications of 10.7, as well as a longer operation time and hospital stay. The presence of previous upper abdominal surgery with AC and obesity had a substantial effect on conversion, with an odds ratio of 87.1 compared with the reference group. LC is safe in patients with AC, previous abdominal surgery, or obesity. However, the presence of inflammation alone or in combination with obesity and/or previous (especially upper) abdominal surgery is the main factor that influences the adverse outcomes of LC.

A survey of the timing and approach to the surgical management of patients with acute cholecystitis in Japanese hospitals

BACKGROUND/PURPOSE

Despite the fact that there is evidence advocating early laparoscopic cholecystectomy for acute cholecystitis (AC), the practice of this treatment has not been investigated sufficiently. This study was designed to assess the current practice of laparoscopic cholecystectomy for AC among Japanese general surgeons.

METHODS

A postal questionnaire was sent to the 291 councillors of the Japanese Society of Abdominal Emergency Medicine in order to ascertain their current management of patients with AC.

RESULTS

The response rate was 72.5%. A policy of early cholecystectomy for AC was adopted by 41.7% of the responding surgeons. However, almost the same percentage of surgeons routinely managed their patients conservatively, and opted for delayed cholecystectomy at a later date. The adoption of laparoscopic cholecystectomy was made by 79.1% of surgeons. Laparoscopic cholecystectomy for patients with AC who had percutaneous transhepatic gallbladder drainage (PTGBD) was adopted by 73.9% of the surgeons. Of the surgeons opting for laparoscopic cholecystectomy, 37.3% performed intraoperative cholangiography laparoscopically for all patients with AC.

CONCLUSIONS

Although early cholecystectomy for patients with AC was not adopted by the majority of the surgeons who responded, laparoscopic cholecystectomy was a common procedure for early and delayed cholecystectomy. Despite evidence that strongly supports the use of early cholecystectomy, the use of this treatment remains suboptimal in Japan.

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.

Role of fundus-first laparoscopic cholecystectomy in the management of acute cholecystitis in elderly patients

BACKGROUND

Conversion from laparoscopic cholecystectomy to open cholecystectomy leads to the loss of the advantages of this minimally invasive procedure and significantly increases length of hospital stay as well as cost. The conversion from laparoscopic to open cholecystectomy is more frequent among patients with acute cholecystitis and in elderly patients. This study evaluated whether fundus-first laparoscopic cholecystectomy could lower the conversion rate in geriatric patients with acute cholecystitis.

MATERIALS AND METHODS

During a twelve-month period, 112 patients (36 of them age 65 years or older) underwent fundus-first laparoscopic cholecystectomy for acute cholecystitis in a tertiary care university hospital in central Taiwan.

RESULTS

The conversion rate in the elderly patients was 2.7% (1/36). No major perioperative complications were observed. Minor complications--port-site infection and subhepatic fluid collection-occurred in two patients (5.5%).

CONCLUSION

Laparoscopic cholecystectomy with a fundus-first approach is a safe, effective operative procedure for elderly patients with acute cholecystitis when performed by an experienced laparoendoscopic surgeon.

Risk factors for perioperative complications in patients undergoing laparoscopic cholecystectomy: analysis of 22,953 consecutive cases from the Swiss Association of Laparoscopic and Thoracoscopic Surgery database

BACKGROUND

Reliable risk factors for perioperative complications in patients undergoing laparoscopic cholecystectomy would be extremely useful to optimize the clinical management. This study aimed to determine risk factors that can be used for predicting perioperative complications.

STUDY DESIGN

Possible risk factors for perioperative complications in patients undergoing laparoscopic cholecystectomy for acute and chronic cholecystitis were analyzed by a stepwise logistic regression model using data from the Swiss Association of Laparoscopic and Thoracoscopic Surgery (SALTS) database.

RESULTS

A total of 22,953 patients with a mean (+/-SD) age of 54.5+/-16.1 years (range 17 to 89 years) and a male-to-female ratio of 1:2, underwent elective (85%) and emergency (15%) laparoscopic cholecystectomy. Multivariable analysis showed that male gender (odds ratio [OR]=1.16; p<0.0001), duration of intervention (OR=1.68 per 30 minutes; p<0.0001), body weight (>90 kg versus<60 kg; OR=1.34; p<0.0001), and the surgeon's own experience (>100 versus 11 to 100 interventions; OR=1.36; p<0.0002) were independently associated with an increased intraoperative local complication rate. In addition, male gender (OR=1.21; p<0.02), age (OR=1.12 per 10 years; p<0.0001), intraoperative complications (OR=2.1; p<0.0001), conversion to open surgery (OR=1.25; p<0.01), American Society of Anesthesiologists risk score (ASA score III/IV versus I/II: OR=1.28; p<0.0005), body weight (<60 kg versus>90 kg; OR=1.53; p<0.007), emergency surgery (OR=1.36; p<0.003), and duration of surgery (OR=1.28 per 30 minutes; p<0.0001) were found to be associated with a higher incidence of postoperative local complications. Higher postoperative systemic complications were encountered with conversion (OR=1.5; p<0.0002), ASA score (III/IV versus I/II: OR=1.54; p<0.0001), emergency surgery (OR=1.41; p<0.001), and a prolonged intervention time (OR=1.16 per 30 minutes; p<0.0001).

CONCLUSIONS

For patients undergoing laparoscopic cholecystectomy (LC), the risk of possible perioperative complications can be estimated based on patient characteristics (gender, age, ASA score, body weight), clinical findings (acute versus chronic cholecystitis), and the surgeon's own clinical practice with LC. So in the likelihood of a case being a "difficult cholecystectomy," an experienced surgeon should be involved both in the decision-making process and during the operation. If LC lasts longer than 2 hours, the cumulative risk for perioperative complications is four times higher compared with an intervention that lasts between 30 and 60 minutes, independent of the surgeon's personal skills with LC.

Emergency laparoscopy--current best practice

Emergency laparoscopic surgery allows both the evaluation of acute abdominal pain and the treatment of many common acute abdominal disorders. This review critically evaluates the current evidence base for the use of laparoscopy, both diagnostic and interventional, in the emergency abdomen, and provides guidance for surgeons as to current best practise. Laparoscopic surgery is firmly established as the best intervention in acute appendicitis, acute cholecystitis and most gynaecological emergencies but requires further randomised controlled trials to definitively establish its role in other conditions.

Cholecystitis in neutropenic patients: Retrospective study and systematic review

Abdominal infections are life-threatening complications in neutropenic patients. Among these, neutropenic cholecystitis is relatively rare. Nevertheless, its actual relevance is only investigated by anecdotal reports. We present a consecutive retrospective series of nine patients over a 12-year period. We calculated a frequency of 0.4% among all neutropenic episodes in patients with acute leukemia or aggressive lymphoma undergoing myelosuppressive chemotherapy. Only three of these patients had gallstones. Four patients died during the course of cholecystitis but in none of them cholecystitis was the primary cause of death. Systematic review of the literature revealed 45 patients with neutropenic cholecystitis of whom 26.7% died.

Peritonitis: laparoscopic approach

Background

Laparoscopy has became as the preferred surgical approach to a number of different diseases because it allows a correct diagnosis and treatment at the same time. In abdominal emergencies, both components of treatment – exploration to identify the causative pathology and performance of an appropriate operation – can often be accomplished via laparoscopy. There is still a debate of peritonitis as a contraindication to this kind of approach. Aim of the present work is to illustrate retrospectively the results of a case-control experience of laparoscopic vs. open surgery for abdominal peritonitis emergencies carried out at our institution.

Methods

From January 1992 and January 2002 a total of 935 patients (mean age 42.3 ± 17.2 years) underwent emergent and/or urgent surgery. Among them, 602 (64.3%) were operated on laparoscopically (of whom 112 -18.7% – with peritonitis), according to the presence of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than two previous major abdominal surgeries or massive bowel distension were not treated Laparoscopically. Peritonitis was not considered contraindication to Laparoscopy.

Results

The conversion rate was 23.2% in patients with peritonitis and was mainly due to the presence of dense intra-abdominal adhesions. Major complications ranged as high as 5.3% with a postoperative mortality of 1.7%. A definitive diagnosis was accomplished in 85.7% (96 pat.) of cases, and 90.6% (87) of these patients were treated successfully by Laparoscopy.

Conclusion

Even if limited by its retrospective feature, the present experience let us to consider the Laparoscopic approach to abdominal peritonitis emergencies a safe and effective as conventional surgery, with a higher diagnostic yield and allows for lesser trauma and a more rapid postoperative recovery. Such features make Laparoscopy a challenging alternative to open surgery in the management algorithm for abdominal peritonitis emergencies.

Urgent laparoscopic cholecystectomy in the management of acute cholecystitis: timing does not influence conversion rate

BACKGROUND

The optimal treatment of acute cholecystitis is urgent laparoscopic cholecystectomy. Most reports suggest that a delay of 72 or 96 h from onset of symptoms leads to a higher conversion rate. This study assessed the conversion rate in relation to the timing of urgent laparoscopic cholecystectomy for acute cholecystitis.

METHODS

During a 12 month period, 112 patients received laparoscopic cholecystectomy for acute cholecystitis at a tertiary care university hospital in central Taiwan. Data were collected prospectively.

RESULTS

The overall conversion rate was 3.6% (4/112). Of 62 procedures performed within 72 h from onset of symptoms, 2 were converted, as compared with 2 of 50 procedures after 72 h. Of 76 procedures performed within 96 h from onset of symptoms, 3 were converted, as compared with 1 of 36 procedures after 96 h. There were no mortalities or common bile duct injuries.

CONCLUSIONS

The conversion rate for urgent laparoscopic cholecystectomy among patients with acute cholecystitis can be as low as 3.6%. The timing of urgent laparoscopic cholecystectomy has no impact on the conversion rate.

Lesão iatrogênica da via biliar principal em colecistectomia videolaparoscópica

OBJETIVO: Estudar a incidência, mortalidade e morbidez da lesão iatrogênica da via biliar em um Hospital Universitário onde os pacientes foram operados por vários cirurgiões em diferentes fases de treinamento (residentes e "staffs"). MÉTODO: Estudo retrospectivo de pacientes operados no Hospital Universitário Clementino Fraga Filho da Universidade Federal do Rio de Janeiro (HUCFF-UFRJ) no período entre janeiro de 1992 e dezembro de 2003. Foram pesquisadas as lesões da via biliar principal, o tempo de reconhecimento das mesmas (per ou pós operatória) e o tipo de reparo utilizado. RESULTADOS: Foram estudados 1589 pacientes com índice de lesão da via biliar de 0.25%, as quais ocorreram principalmente nos últimos anos do uso da técnica no hospital. CONCLUSÕES: A incidência de lesões da via biliar foi semelhante à da literatura e bastante próxima à da cirurgia convencional, e não esteve diretamente relacionada à curva de aprendizado do cirurgião.

Laparoscopy for abdominal emergencies

BACKGROUND

Emergency laparoscopic exploration can be used to identify the causative pathology of acute abdominal pain. Laparoscopic surgery also allows treatment of many intraabdominal disorders. This report was prepared to describe the effectiveness of laparoscopic surgery compared to laparotomy or nonoperative treatment.

METHODS

A panel of European experts in abdominal and gynecological surgery was assembled and participated in a consensus conference using Delphi methods. The aim was to develop evidence-based recommendations for the most common diseases that may cause acute abdominal pain.

RECOMMENDATIONS

Laparoscopic surgery was found to be clearly superior for patients with a presumable diagnosis of perforated peptic ulcer, acute cholecystitis, appendicitis, or pelvic inflammatory disease. In the emergency setting, laparoscopy is of unclear or limited value if adhesive bowel obstruction, acute diverticulitis, nonbiliary pancreatitis, hernia incarceration, or mesenteric ischemia are suspected. In stable patients with acute abdominal pain, noninvasive diagnostics should be fully exhausted before considering explorative surgery. However, diagnostic laparoscopy may be useful if no diagnosis can be found by conventional diagnostics. More clinical data are needed on the use of laparoscopy after blunt or penetrating trauma of the abdomen.

CONCLUSIONS

Due to diagnostic and therapeutic advantages, laparoscopic surgery is useful for the majority of conditions underlying acute abdominal pain, but noninvasive diagnostic aids should be exhausted first. Depending on symptom severity, laparoscopy should be advocated if routine diagnostic procedures have failed to yield results.

Risk factors for conversion of laparoscopic cholecystectomy to open cholecystectomy

BACKGROUND

Conversion to open cholecystectomy is still required in some patients. The aim of this study was to evaluate preoperative factors associated with conversion to open cholecystectomy in elective cholecystectomy and acute cholecystitis.

METHODS

The records of 1,804 patients who underwent cholecystectomy from May 1992 to January 2004 were reviewed retrospectively. The demographics and preoperative data of patients who required conversion to laparotomy were compared to those with successful laparoscopic cholecystectomy.

RESULTS

Conversion to open cholecystectomy was needed in 94 patients (5.2%),of which 44 (2.8%) had no inflammation and 50 (18.4%) had acute inflammation of the gallbladder. Male gender, age older than 60 years, previous upper abdominal surgery, diabetes, and severity of inflammation were all significantly correlated with an increased conversion rate to laparotomy. Also, the conversion from laparoscopic to open cholecystectomy in acute cholecystitis patients was associated with greater white blood cell count, fever, elevated total bilirubin, aspartate transaminase, and alanine transaminase levels, and the various types of inflammation.

CONCLUSIONS

None of these risk factors were contraindications to laparoscopic cholecystectomy. This may help predict the difficulty of the procedure and permit the surgeon to better inform patients about the risk of conversion from laparoscopic to open cholecystectomy.

Sex-based analysis of the outcome of laparoscopic cholecystectomy for acute cholecystitis

BACKGROUND

Complicated acute cholecystitis, for example when empyema or gangrene is present, is associated with increased postoperative morbidity and mortality rates. The aim of this study was to determine the correlation between sex, the severity of acute cholecystitis and the outcome of laparoscopic cholecystectomy.

METHODS

Of 674 patients in whom laparoscopic cholecystectomy was attempted, 348 had chronic cholecystitis and 326 had acute cholecystitis. The medical records of the latter were reviewed retrospectively.

RESULTS

The proportion of male patients significantly increased with the severity of cholecystitis: 37.4 per cent of those with chronic cholecystitis were men, compared with 44.4 per cent of those with uncomplicated acute cholecystitis and 57 per cent of those with complicated acute cholecystitis (P = 0.001). Multivariate analysis showed that advanced age (odds ratio 2.24; P = 0.004) and male sex (odds ratio 1.76; P = 0.029) independently predicted complicated acute cholecystitis. The conversion rate to open operation was 6.4 per cent in men and 5.9 per cent in women (P = 0.843). The postoperative complication rate was 10.3 and 8.2 per cent respectively (P = 0.528).

CONCLUSION

Male sex was identified as a risk factor for more severe acute cholecystitis, but outcome for men after laparoscopic cholecystectomy was not significantly different from that for women.

Le risque de plaies biliaires au cours de la cholécystectomie par laparoscopie

The incidence of iatrogenic injuries of the bile ducts has increased significantly since laparascopic cholecystectomy became the "gold standard" in the treatment of cholelithiasis. The incidence of major biliary ductal injury ranges from 0.25% to 0.74%, and of minor injury from 0.28% to 1.7%. The cause of the injury is not always clearly identifiable. In more than half the cases, the injury occurs during maneuvers to isolate the cystic duct or to free the gallbladder from the common bile duct. These maneuvers may be more difficult and consequently more dangerous when there is significant inflammation as may be seen in acute cholecystitis, or in case of obesity, cirrhosis with portal hypertension, previous surgery with peritoneal adhesions, or anatomic variations of the hepatic pedicle. Pre-operative evaluation of clinical risk factors should be coupled with intra-operative caution and instrumental evaluation. The increase in frequency of iatrogenic biliary injuries can not be attributed simply to the inexperience of the surgeon or the learning curve as was initially suggested. Many injuries are due, rather, to the surgeon's failure to respect basic technical rules, long established for open cholecystectomy and which should not be modified for the laparoscopic technique. While routine cholangiography does not offer complete protection from iatrogenic ductal injuries, it is essential to visualize the biliary tract whenever a lesion of the ductal system is clearly identified or even suspected. In such cases, facility with the technique of intraoperative cholangiography and a knowledge of the radiological anatomy of the biliary tree are essential for an accurate and complete intraoperative evaluation of the biliary injury. Finally, in the presence of acute or chronic inflammation or other factors for technical difficulty (obesity, cirrhosis, previous surgery, anatomic variations, intraoperative bleeding), the surgeon must not hesitate to consider conversion to an open surgical approach. In such complicated cases, even the open approach is not a guarantee against biliary injury; there is no substitute for experience and caution in biliary surgery.

Laparoscopic cholecystectomy in acute cholecystitis: indication, technique, risk and outcome

BACKGROUND

Laparoscopic cholecystectomy (LC) has become the treatment of choice for symptomatic cholelithiasis. However, the laparoscopic approach has remained controversial for patients with acute cholecystitis (AC) because of technical difficulties that, compared with open cholecystectomy (OC), might lead to higher complication rates, particularly common bile duct (CBD) injuries and infection.

METHODS

We reviewed recent clinical findings on feasibility, safety and potential benefits of LC in patients with AC. An electronic search using the PubMed and MEDLINE databases was performed using the terms laparoscopic cholecystectomy, open cholecystectomy and acute cholecystitis. Pertinent references from articles and books not identified by the search engines were also retrieved. Relevant surgical textbooks were also reviewed.

CONCLUSIONS

The early laparoscopic approach has been shown to be technically feasible and at least equally as safe as the open approach. However, extensive inflammation, adhesions and consequent increased oozing can make laparoscopic dissection of Calot's triangle and recognition of the biliary anatomy hazardous and difficult. Therefore, conversion to OC remains an important treatment option to secure patient safety in such difficult conditions. The question of whether intraoperative cholangiography (IOC) should be used routinely or only selectively has never been resolved. Proponents for each side have put forward compelling arguments.

Safe laparoscopic surgery in the elderly

BACKGROUND

The elderly are more prone to complications of surgery because of comorbidity, and they may benefit most from a minimally invasive approach. This study was intended to evaluate the safety of the use of a laparoscopic approach for emergency and elective surgery in elderly patients.

METHODS

From January 2000 to June 2001, all patients over 75 years of age who underwent a procedure that began laparoscopically were included. Physiologic and operative scores according to the POSSUM scoring system were recorded. These were then used to calculate predicted morbidity and mortality by both the POSSUM and P-POSSUM systems. Predicted outcomes were compared with actual outcomes.

RESULTS

One hundred sixty-two patients with a mean age of 80 years were included; 52% were emergency cases. The overall morbidity was 14.5% and the mortality rate was 1.8%. Fourteen procedures (8.4%), all emergencies, were converted. Both mortality and morbidity rates were lower than the predicted values (P = 0.001 and P = 0.0001, respectively).

CONCLUSIONS

A laparoscopic approach can be used safely in an elderly population undergoing surgery in a daily practice for miscellaneous conditions, whether elective or emergency operations.

Does the Complication Rate Increase in Laparoscopic Cholecystectomy for Acute Cholecystitis?

BACKGROUND

Laparoscopic cholecystectomy (LC) has replaced open cholecystectomy for the treatment of gallbladder disease. Despite the well-accepted success of LC in chronic cholecystitis, the efficacy of this technique has been subject to some debate in acute cholecystitis (AC). This study was designed to evaluate our institution's experience with LC for AC and chronic symptomatic calculous cholecystitis (CC), based on complication and conversion rates to open surgery.

PATIENTS AND METHODS

The records of 1158 patients with LC from September 1991 to December 2001 were analyzed. The parameters of age, gender, early and late complication rates, and conversion rates from LC to open cholecystectomy were compared in patients with AC and CC.

RESULTS

During the study period, LC was performed in 1158 patients. Of these, 162 patients had AC (group 1) and 996 patients had CC (group 2). The conversion rates were 4.3% (7/162) in group 1 and 2.4% (24/996) in group 2. The complication rates were not significantly different (5.6% in group 1, 5.1% in group 2, P > 0.05). Difficulty in dissection around Calot's triangle and obscure anatomy were the main reasons for conversion to conventional open surgery. The mortality rate was 1.2% in group 1 and 0.01% in group 2.

CONCLUSION

LC appears to be a reliable, safe, and effective treatment modality for AC and CC. The surgical approach should be performed carefully because of the spectrum of potential hazards of the laparoscopic procedure. Conversion and complication rates are similar in both AC and CC groups, and improve as surgeons gain experience.

Implementation of a specialist-led service for the management of acute gallstone disease

Background

The ‘gold standard’ treatment for acute cholecystitis and biliary colic requiring hospital admission is urgent laparoscopic cholecystectomy. This is not routinely available in all hospitals.

Methods

A retrospective audit of emergency admissions with acute cholecystitis or biliary colic from January to December 2000 led to the development and implementation of a specialist-led protocol for the urgent management of acute gallstone disease. A second audit was carried out covering the 6 months after implementation.

Results

One hundred and fifty-eight patients were admitted with acute cholecystitis or biliary colic in the first audit period and 110 in the second interval. The rate of cholecystectomy at index admission increased from 37·3 to 67·3 per cent, at a median of 3 days after admission, and the conversion rate to open surgery fell from 32 to 12 per cent. Median hospital stay fell from 9 to 5·5 days, and the unplanned readmission rate decreased from 19·0 to 3·6 per cent.

Conclusion

Urgent cholecystectomy for the management of acute gallstone disease is feasible and achievable in an acute services hospital with a specialist upper gastrointestinal team. It can lead to a reduced conversion rate, shorter hospital stay, fewer unplanned readmissions, an acceptable operating time and a low complication rate. The protocol is recommended for implementation in other hospitals.
