Laparoscopic cholecystectomy and common bile duct exploration are safe for older patients

Laparoscopic common bile duct exploration with primary closure is preferred for selected elderly individuals with choledocholithiasis

Background

Laparoscopic common bile duct exploration with primary closure (LCBDE-PC) exhibits more benefits than other surgeries for patients with choledocholithiasis. It remains unclear whether it is feasible for and beneficial to elderly individuals. This study aimed to clarify and stratify elderly patients who would benefit from LCBDE-PC.

Methods

A retrospective study of 1240 patients with choledocholithiasis who underwent laparoscopic procedures between 2011 and 2019 was conducted. Patients were divided into the young group (<65 years old, n = 708) and the elderly group (≥65 years old, n = 532). Perioperative outcomes were compared between the two groups.

Results

Laparoscopic common bile duct exploration with primary closure was successfully performed in 90.20% of the elderly and 94.20% of the young. No significant differences were observed between the two groups regarding reoperation, postoperative bile leakage, residual stones, drainage removal, and postoperative mortality. Compared with the young, the elderly had longer postoperative hospital stay (p = 0.035) and delayed postoperative eating time (p = 0.036) in the matched cohort. Independent risk factors for failed LCBDE-PC were preoperative pancreatitis (p = 0.018), year of the surgeon's experience (p = 0.008), preoperative C-reactive protein level (p = 0.034), preoperative total bilirubin (p = 0.021), impacted common bile duct (CBD) stones (p = 0.006), blood loss (p = 0.001), and edema of the CBD (p = 0.001). A novel nomogram for predicting failed LCBDE-PC in elderly individuals exhibited a sufficient discriminative ability according to the estimated area under the curve (AUC) of 0.869 (95% CI: 0.817-0.921, p < 0.01).

Conclusion

Laparoscopic common bile duct exploration with primary closure is safe, feasible, and effective for elderly individuals with choledocholithiasis. Elderly patients with a high risk of failed LCBDE-PC should be cautious of undergoing LCBDE-PC.

Which octogenarian patients are at higher risk after cholecystectomy for symptomatic gallstone disease? A single center cohort study

BACKGROUND

Incidence of gallstones in those aged ≥ 80 years is as high as 38%-53%. The decision-making process to select those oldest old patients who could benefit from cholecystectomy is challenging.

AIM

To assess the risk of morbidity of the “oldest-old” patients treated with cholecystectomy in order to provide useful data that could help surgeons in the decision-making process leading to surgery in this population.

METHODS

A retrospective study was conducted between 2010 and 2019. Perioperative variables were collected and compared between patients who had postoperative complications. A model was created and tested to predict severe postoperative morbidity.

RESULTS

The 269 patients were included in the study (193 complicated). The 9.7% of complications were grade 3 or 4 according to the Clavien-Dindo classification. Bilirubin levels were lower in patients who did not have any postoperative complications. American Society of Anesthesiologists scale 4 patients, performing a choledocholithotomy and bilirubin levels were associated with Clavien-Dindo > 2 complications (P < 0.001). The decision curve analysis showed that the proposed model had a higher net benefit than the treating all/none options between threshold probabilities of 11% and 32% of developing a severe complication.

CONCLUSION

Patients with American Society of Anesthesiologists scale 4, higher level of bilirubin and need of choledocholithotomy are at the highest risk of a severely complicated postoperative course. Alternative endoscopic or percutaneous treatments should be considered in this subgroup of octogenarians.

Perioperative outcomes after laparoscopic cholecystectomy in elderly patients: a systematic review and meta-analysis

BACKGROUND

Laparoscopic cholecystectomy is increasingly performed in an ever ageing population; however, the risks are poorly quantified. The study aims to review the current evidence to quantify further the postoperative risk of cholecystectomy in the elderly population compared to younger patients.

METHOD

A systematic literature search of PubMed, EMBASE and the Cochrane Library databases were conducted including studies reporting laparoscopic cholecystectomy in the elderly population. A meta-analysis was reported in accordance with the recommendations of the Cochrane Library and PRISMA guidelines. Primary outcome was overall complications and secondary outcomes were conversion to open surgery, bile leaks, postoperative mortality and length of stay.

RESULTS

This review identified 99 studies incorporating 326,517 patients. Increasing age was significantly associated with increased rates of overall complications (OR 2.37, CI95% 2.00-2.78), major complication (OR 1.79, CI95% 1.45-2.20), risk of conversion to open cholecystectomy (OR 2.17, CI95% 1.84-2.55), risk of bile leaks (OR 1.50, CI95% 1.07-2.10), risk of postoperative mortality (OR 7.20, CI95% 4.41-11.73) and was significantly associated with increased length of stay (MD 2.21 days, CI95% 1.24-3.18).

CONCLUSION

Postoperative outcomes such as overall and major complications appear to be significantly higher in all age cut-offs in this meta-analysis. This study demonstrated there is a sevenfold increase in perioperative mortality which increases by tenfold in patients > 80 years old. This study appears to confirm preconceived suspicions of higher risks in elderly patients undergoing cholecystectomy and may aid treatment planning and informed consent.

Laparoscopic common bile duct exploration for elderly patients with choledocholithiasis: a systematic review and meta-analysis

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) has been becoming more and more popular in patients with symptomatic choledocholithiasis. However, the safety and effectiveness of LCBDE in elderly patients with choledocholithiasis is still uncertain. This meta-analysis is aimed to appraise the safety and feasibility of LCBDE for elderly patients with choledocholithiasis.

MATERIALS AND METHODS

Studies comparing elderly patients and younger patients who underwent LCBDE for common bile duct stone were reviewed and collected from the PubMed, Medline, EMBASE, and Cochrane Library. Primary outcomes were stone clearance rate, overall complication rate, and mortality rate. Secondary outcomes were operative time, conversion rate, pulmonary complication, bile leakage, reoperation, residual stone rate, and recurrent stone rate.

RESULTS

Nine studies, including two prospective studies and seven retrospective studies, met the inclusion criteria. There were 2004 patients in this meta-analysis, including 693 elderly patients and 1311 younger patients. There was no statistically significant difference between elderly patients and younger patients regarding stone clearance rate (OR 0.73; 95% CI 0.42-1.26; p = 0.25), overall complication rate (OR 1.31; 95% CI 0.94-1.82; p = 0.12), and mortality rate (OR 2.80; 95% CI 0.82-9.53; p = 0.10). Similarly, the operative time, conversion rate, bile leakage, reoperation, residual stone rate, and recurrent stone rate showed no significant difference between two groups (p > 0.05). While elderly patients showed high risk for pulmonary complication (OR 4.41; 95% CI 1.78-10.93; p = 0.001) compared with younger patients.

CONCLUSION

Although there is associated with higher pulmonary complication, LCBDE is still considered as a safe and effective treatment for elderly patients with choledocholithiasis.

Primary closure after laparoscopic common bile duct exploration is feasible for elderly patients: 5-Year experience at a single institution

OBJECTIVE

Laparoscopic common bile duct exploration (LCBDE) has been demonstrated safety and effective for patients with gallbladder stones and extrahepatic bile duct stones, however few studies reported its suitability for the treatment of elderly patients. Thus, our study aims to investigate the safety and feasibility of primary closure after LCBDE in the treatment of elderly patients.

METHODS

408 out of 499 patients with Gallbladder stones complicated with choledocholithiasis who were undergone LCBDE and primary closure were divided into two groups: Group A (<65 years old, n = 249) and Group B (≥65 years old, n = 159) and the related clinical data were compared and analyzed by statistical method.

RESULTS

Pre-operative American Society of Anesthesiologists (ASA) score of elderly patients was significantly higher than the younger patients (P < 0.05). In both groups, the positive rate of Choledocholithiasis and bile sludge at exploration, number of stones in CBD, utilization rate of Electro-hydraulic lithotripsy, estimated blood loss, successful duct clearance, the rate of postoperative bile leakage, postoperative bile duct stricture, reoperation, stone recurrence, and other postoperative complications showed no significant difference (p > 0.05). There were also no statistical differences between both groups in time to removal of drainage, postoperative hospital stay, readmission within 30 days and mortality (p > 0.05).

CONCLUSIONS

It is safe and feasible to treat the elderly patients with common bile duct stones under the premise of strict surgical indications, skilled laparoscopic procedures and accurate endoscopic suture techniques.

Efficacy and safety of laparoscopic bile duct exploration versus endoscopic sphincterotomy for concomitant gallstones and common bile duct stones: A meta-analysis of randomized controlled trials

BACKGROUND

The purpose of this study was to compare the efficacy and safety of laparoscopic cholecystectomy (LC) plus laparoscopic common bile duct (CBD) stones exploration (LCBDE) with LC plus endoscopic sphincterotomy (EST) in the treatment of patients with gallstones and CBD stones.

METHODS

The authors searched PubMed, Web of Science, and Embase to identify relevant studies. Risk ratios (RRs) were pooled to compare stone clear, retained stone, conversion to other procedures, and complications. Weighted mean differences (WMDs) were pooled to compare operative time, and length of hospital stay. A fixed-effects model or random-effects model was used to pool the estimates, according to the heterogeneity among the included studies.

RESULTS

A total of 11 randomized controlled trials (RCTs) involving 1663 patients were included in this meta-analysis. The pooled estimate suggested that LC-LCBDE had comparable effects with LC-EST in terms of CBD stone clear rate (RR = 1.02, 95% CI: 0.95, 1.09; P = .583), retained stones rate (RR = 1.27, 95% CI: 0.51, 3.19; P = .607), and length of hospital stay (WMD = -0.96 days, 95% CI: -2.20, 0.28). In addition, LC-LCBDE was associated with significantly higher conversion rate (RR = 1.59, 95% CI: 1.08, 2.35; P = .019) and less operative time (WMD = -11.55 minutes, 95% CI: -16.68, -6.42; P < .001) than LC-EST. The incidence of complications was not significant difference between the 2 surgical approaches (RR = 1.07, 95% CI: 0.86, 1.34; P = .550).

CONCLUSION

Based on the current evidence, both LC-LCBDE and LC-EST were highly effective in detecting and removing CBD stones and were equivalent in complications. However, our results might be biased by the limitations. Large-scale well-designed RCTs are needed to confirm our findings.

Laparoscopic common bile duct exploration: a safe and definitive treatment for elderly patients

BACKGROUND

Common bile duct (CBD) stone is one of the most common diseases among elderly people. In recent decades, there are numerous studies regarding the safety and efficacy of laparoscopic common bile duct exploration (LCBDE). Elderly patients are often regarded as high-risk patients because they are more likely to present with age-specific deterioration of organ function and coexisting chronic diseases, which may reduce their tolerance of laparoscopic surgery. Although laparoscopic surgery for choledocholithiasis is now widely accepted as the treatment for CBD stone, its appropriateness for the treatment of elderly patients or those with coexisting high-risk patients has not been well established. Therefore, the objective of this paper is to analyze the safety and efficacy of LCBDE in elderly patients.

METHODS

Between January 2012 and November 2015, 376 patients underwent LCBDE in our center. Based on their ages, they were divided into two groups, and a retrospective study was performed. By making comparisons between younger group who were younger than 70 years (n = 253) and elderly group who were 70 years old or older (n = 123), the demographics, clinical characteristics, laboratory data, operative parameters and outcomes were analyzed.

RESULTS

Before operation, elderly patients had more coexisting chronic diseases and risk factors, such as arterial hypertension, heart diseases, pulmonary diseases and previous abdominal surgery (P < 0.05). In both groups, LCBDE was equally successful with a high clearance rate (100 % in elderly patients vs. 98.8 % in younger group, P = 0.554). Besides, the operating time, intraoperative blood loss, postoperative hospital stay, total costs and overall complication showed no significant difference between two groups (P > 0.05). There was no major bile duct injury or death in either group.

CONCLUSION

Although elderly patients are frequently confronted with coexisting disorders, LCBDE can be considered as a safe and effective technique in choledocholithiasis treatment for elderly patients.

Results of Medium Seventeen Years' Follow-Up after Laparoscopic Choledochotomy for Ductal Stones

Introduction. In a previously published article the authors reported the long-term follow-up results in 138 consecutive patients with gallstones and common bile duct (CBD) stones who underwent laparoscopic transverse choledochotomy (TC) with T-tube biliary drainage and laparoscopic cholecystectomy (LC). Aim of this study is to evaluate the results at up to 23 years of follow-up in the same series. Methods. One hundred twenty-one patients are the object of the present study. Patients were evaluated by clinical visit, blood assay, and abdominal ultrasound. Symptomatic patients underwent cholangio-MRI, followed by endoscopic retrograde cholangiopancreatography (ERCP) as required. Results. Out of 121 patients, 61 elderly patients died from unrelated causes. Fourteen patients were lost to follow-up. In the 46 remaining patients, ductal stone recurrence occurred in one case (2,1%) successfully managed by ERCP with endoscopic sphincterotomy. At a mean follow-up of 17.1 years no other patients showed signs of bile stasis and no patient showed any imaging evidence of CBD stricture at the site of choledochotomy. Conclusions. Laparoscopic transverse choledochotomy with routine T-tube biliary drainage during LC has proven to be safe and effective at up to 23 years of follow-up, with no evidence of CBD stricture when the procedure is performed with a correct technique.

Common bile duct exploration in an elderly Asian population

Common bile duct exploration (CBDE) is an accepted treatment for choledocholithiasis. This procedure is not well studied in the elderly population. Here we evaluate the results of CBDE in elderly patients (>70 years) and compare the open (group A) with the laparoscopic group (group B). A retrospective review was performed of elderly patients with proven common bile duct (CBD) stones who underwent CBDE from January 2005 to December 2009. There were 55 patients in group A and 33 patients in group B. Mean age was 77.6 years (70-91 years). Both groups had similar demographics, liver function tests, and stone size-12 mm (range, 5-28 mm). Patients who had empyema (n = 9), acute cholecystitis (n = 15), and those who had had emergency surgery (n = 28) were more likely to be in group A (P < 0.05). The mean length of stay for group A was 11.7 ± 7.3 days; for group B, 5.2 ± 6.3 days; the complication rate was higher in group A (group A, 38.2%; group B, 8.5%; P = 0.072). The overall complication and mortality rate was 29.5% and 3.4%, respectively. CBDE can be performed safely in the elderly with accepted morbidity and mortality. The laparoscopic approach is feasible and safe in elective setting even in the elderly.

Does laparoscopic approach impair T-tube-related sinus-tract formation?

PURPOSE

Postoperative morbidity after bile duct exploration with T-tube insertion is mainly related to tube removal and incomplete sinus-tract formation leading to serious complications. Laparoscopic surgery reduces abdominal adhesion formation and diminishes tissue trauma and inflammatory response to surgery, which is essential for sinus-tract formation. This study evaluates if complication rate of T-tube removal is increased after laparoscopic bile duct exploration.

METHODS

Between January 2004 and January 2011, 94 patients underwent a T-tube insertion following choledocolithotomy (44 and 50 patients in the laparoscopic and open surgery group, respectively). Epidemiological data, preoperative characteristics, day of tube removal, and morbidity rates were analyzed.

RESULTS

Global T-tube removal-related biliary complication rate was 14.9% (18.2% in the laparoscopic group vs. 12% in the open surgery group). Although the day of T-tube removal was significantly delayed, there was a slight increased incidence of biliary peritonitis requiring reintervention in the laparoscopic surgery group (6.9% vs. 2%).

CONCLUSIONS

We reveal that T-tube removal is associated with significant morbidity. There was no statistical difference between the laparoscopic and the open surgery group, although global biliary complications after tube removal were slightly increased and bile spillage was worse delimited when T-tube was inserted laparoscopically. Laparoscopic approach may diminish inflammatory response and adherence development and impair, and therefore sinus-tract formation.

Laparoscopic common bile duct exploration for elderly patients: as a first treatment strategy for common bile duct stones

Purpose

Common bile duct (CBD) stone is a relatively common disease in elderly patients. There have been many reports about the efficacy and safety of LCBDE. But for elderly patients, only a few studies about its efficacy and safety exist. The aim of this study is to evaluate the efficacy, safety and the surgical outcome of LCBDE in patients who are 70 years or older and compare the results with those of the younger group.

Methods

From January 2000 to November 2009, 132 patients underwent LCBDE. We divided these patients into two groups according to age and conducted a retrospective analysis. The elderly group included patients who were 70 years old or older (n = 64), and the younger group included those who were younger than 70 (n = 68). The elderly group was compared to the younger group with respect to their clinical characteristics, operation time, postoperative hospital stay, open conversion rate, first meal time, postoperative complication, recurrence rate and mortality.

Results

The elderly group showed high American Society of Anesthesiologists score (2.2 vs. 1.9) (P = 0.003), preoperative morbidity (47 vs. 29) (P < 0.001), and previous abdominal operation (18 vs. 14) (P = 0.046). There were no significant differences in mean operation time, postoperative hospital stay, first meal time, recurrence rate, remnant stone, complication rates or mortality in both groups (P > 0.05).

Conclusion

LCDBE is a safe and effective treatment modality for CBD stones not only for younger patients but also for elderly patients.

Comparison of long-term results of laparoscopic and endoscopic exploration of common bile duct

Background:

To compare long term results of laparoscopic and endoscopic exploration of common bile duct, to assess post-procedure quality of life.

Materials and Methods:

From September 1992 to August 2003, we performed 4058 cholecystectomies, out of which 479 (11.80%) patients had choledocholithiasis. There were 163 males and 316 females. Mean age was 63.65 ± 5.5 years. These patients were put in two groups. In the first group of 240 patients, a majority of patients underwent two-stage procedures. ERCP/ES was performed in 210 (87.50%) cases. In the second group of 239 patients, a majority of patients underwent single-stage procedures. ERCP/ES was done in 32 (13.38%) cases.

Results:

Mortality was zero in both groups. Morbidity was 15.1% in first group and 7.5% in second group. Mean hospital stay was 11.7 ± 3.2 days in first group and 6.2 ± 2.1 days in second group. Average operative time was 95.6 ± 20 minutes in first group and 128.4 ± 32 minutes in second group. Completed questionnaires received from 400 (83.50%) patients revealed better long-term results in the second group. Clinical features of low-grade cholangitis were seen in 20% of patients who underwent ES. Hence the post-procedure quality of life in patients who underwent single-stage procedures was definitely much better, because of minimal damage of sphincter of Oddi.

Conclusions:

Single-stage laparoscopic operations provide better results and shorter hospital stay. Damage to sphincter of Oddi should be minimal, to avoid long-term low-grade cholangitis. In young patients, the operation of choice should be single-stage laparoscopic procedure with absolutely no damage to sphincter of Oddi.

A randomized, clinical trial to compare endoscopic sphincterotomy and subsequent laparoscopic cholecystectomy with primary laparoscopic bile duct exploration during cholecystectomy in higher risk patients with choledocholithiasis

INTRODUCTION

Outcomes after endoscopic sphincterotomy (ES) and subsequent laparoscopic cholecystectomy (LC) versus laparoscopic bile duct exploration (LBDE) during LC are comparable in fit patients with choledocholithiasis. This randomized, clinical trial aimed to determine the optimum treatment in patients with higher medical risk.

MATERIALS AND METHODS

Ninety-one higher risk patients with evidence of bile duct stones were randomized to ES/LC (group A) or LBDE during LC (group B). The primary outcome measure was duct clearance. Secondary outcome measures were complications, number of procedures per patient, conversion, and postoperative hospital stay (POS).

RESULTS

Forty-seven patients were randomized to ES/LC and 44 to LBDE. The median age was 74.56 years. On an intention-to-treat basis, duct clearance was achieved in 29 of 47 of group A and 44 of 44 of Group B patients (P < 0.001). Clavien Grade II-V complications occurred in 8 of 47 and 8 of 44 patients (P = 0.884), the median number of procedures was 2 (2-3) and 1 (1-1) (P < 0.001), 2 of 47 and 4 of 44 patients required conversion (P = 0.676), and the median POS was 3 (2-7) and 5 (2-7) days (P = 0.825), respectively.

CONCLUSIONS

There was no difference between approaches to duct clearance in terms of postoperative stay, complications, or conversion in higher risk patients, but the laparoscopic approach was more effective and efficient and avoided unnecessary procedures.

Reoperation of biliary tract by laparoscopy: Experiences with 39 cases

AIM: To evaluate the safety and feasibility of biliary tract reoperation by laparoscopy for the patients with retained or recurrent stones who failed in endoscopic sphincterotomy.

METHODS: A retrospective analysis of data obtained from attempted laparoscopic reoperation for 39 patients in a single institution was performed, examining open conversion rates, operative times, complications, and hospital stay.

RESULTS: Out of the 39 cases, 38 (97%) completed laparoscopy, 1 required conversion to open operation because of difficulty in exposing the common bile duct. The mean operative time was 135 min. The mean post-operative hospital stay was 4 d. Procedures included laparoscopic residual gallbladder resection in 3 cases, laparoscopic common bile duct exploration and primary duct closure at choledochotomy in 13 cases, and laparoscopic common bile duct exploration and choledochotomy with T tube drainage in 22 cases. Duodenal perforation occurred in 1 case during dissection and was repaired laparoscopically. Retained stones were found in 2 cases. Postoperative asymptomatic hyperamylasemia occurred in 3 cases. There were no complications due to port placement, postoperative bleeding, bile or bowel leakage and mortality. No recurrence or formation of duct stricture was observed during a mean follow-up period of 18 mo.

CONCLUSION: Laparoscopic biliary tract reoperation is safe and feasible if it is performed by experienced laparoscopic surgeons, and is an alternative choice for patients with choledocholithiasis who fail in endoscopic sphincterectomy.

Laparoscopy combined with choledochoscopy for the treatment of bile duct calculi: 160 cases analysis

AIM: To discuss techniques and effects of laparosocopy combined with choledochosopy in choledocholithotomy.

METHODS: A retrospective analysis was performed of clinical data on 160 patients with choledochlithiasis that were treated with laparoscopic common bile duct exploration and stone removal with choledochosopy from January 1998 to December 2006 at our hospital.

RESULTS: The laparosocopic operation was successfully completed in 159 patients, and a conversion to open surgery was needed in only 1 patient. The primary suture of the bile duct was performed in 68 patients, while T-tube drainage was conducted in 92 patients. The stones were completely removed during the operation in 156 patients; stone removal under choledochosopy was required in 4 patients after the operation. The operation duration was 70-120 min (mean, 115 min). The postoperative hospital stay was 4-11 d (mean, 6 d). No bile duct hemorrhage or abdominal infection was seen. No fatalities were noted. Postoperative biliary leakage occurred in 2 patients, and both were cured with a second suture and drainage with laparoscopy. Follow-up observations in 120 patients for 6-36 mo (mean, 18 mo) found no recurrence of bile duct stones or long-term complications.

CONCLUSION: Laparoscopy combined with choledochoscopy for choledocholithotomy has the advantage of less invasion, rapid recovery and shorter hospitalization. It is a safe and effective method for bile duct stones.

Evaluation of laparoscopic treatment of common bile duct stones in a prospective series of 505 patients: indications and results

BACKGROUND

The aim of this prospective study was the evaluation of the laparoscopic treatment of common bile duct stones (CBDS) and its indications.

METHODS

Five hundred five patients who underwent laparoscopic treatment of CBDS from October 1990 to September 2006 were included in the prospective study. The mean age of the patients was 63 years (range = 19-93). Four hundred fifteen patients were classified ASA I and ASA II and 90 were ASA III and ASA IV. CBDS were suspected or diagnosed preoperatively in 373 patients (73.8%) and diagnosed at intraoperative cholangiography (IOC) in 132 patients (26.2%). A transcystic duct extraction (TCDE) was attempted in 254 patients (50.4%) and a primary choledochotomy in 251 patients (49.6%). Biliary drainage after choledochotomy was used in 148 cases (48.8%).

RESULTS

TCDE was successful in 191 cases (75.2%). The 63 failures were managed by laparoscopic choledochotomy in 53 cases and by endoscopic sphincterotomy (ES) in 10 cases. A choledochotomy was thus performed in 304 patients and successful in 295 cases (97%). The nine failures were managed by six conversions to laparotomy (2%) and three postoperative ES. The overall success rate was 96.2%. The morbidity rate was 7.9% with 4.8% of local complications and 3.1% of general complications. The mortality rate was 1%. There were 14 residual stones (2.8%) that were managed by a second laparoscopy in two cases and by ES in 12 cases with four failures managed by laparotomy in one case and laparoscopy in three cases.

CONCLUSION

Laparoscopic management of CBDS was effective in more than 96% of cases and particularly safe in ASA I and ASA II patients. It has the advantage over ES followed by laparoscopic cholecystectomy (LS) to be a one-stage procedure.

[Nononcologic abdominal surgery in the elderly]

Due to rising life expectancy of the population, the proportion of elderly patients requiring surgery is rising as well. Present aspects of selected, typical, nononcologic diseases of elderly people are discussed. The key to success in their treatment is not to consider primarily the patient's calendrical age but to assess the individual profile of risk factors on the basis of comorbidities. The kind, extent, and timing of an operation has to be based on this assessment. For the treatment of acute diseases (e.g., complicated ulcera, cholecystitis, appendicitis, mesenteric ischemia, and diverticulitis), a rapid and efficacious diagnostic algorithm is essential that takes into account the reduced functional reserve of old people. Constructive interdisciplinary cooperation and minimally invasive techniques play dominant roles in both diagnosis and therapy. Given these prerequisites, there is no reason to withhold surgical intervention from elderly patients.

Laparoscopic radical nephrectomy in the elderly

OBJECTIVE

To evaluate the efficacy and outcome of laparoscopic radical nephrectomy (LRN) in patients aged >75 years, and to compare the results with those obtained from patients younger than this undergoing laparoscopic surgery for the same indication.

PATIENTS AND METHODS

From a retrospective review of 33 patients aged >75 years undergoing LRN, 28 were for tumour. A group of 28 consecutive patients aged <75 years undergoing laparoscopy for the same indication were used for comparison. The two groups were compared for American Society of Anesthesiology (ASA) physical status score, comorbidity, previous surgical history, operative duration, estimated blood loss, tumour size, complications during and after surgery, conversion rates, time to oral intake and drain removal, perioperative mortality and hospital stay.

RESULTS

Only the initial ASA score was significantly higher for the older patients. All other variables before, during and after surgery were similar for both groups.

CONCLUSIONS

The final outcome of laparoscopic surgery in elderly patients was as promising as in their younger counterparts. Therefore, elderly patients should not be excluded from LRN, even though they usually present with more comorbidities.

Laparoscopic Treatment of Intrahepatic Duct Stone

Between October 1998 and November 1999, 12 patients with IHD stones, without severe ductal stricture, adhesion due to previous exploration, intrahepatic abscess or suspicious malignancy, were in the subjects of this study. A 4-port-technique was performed, with a 4-way flexible choledochoscope, via a choledochotomy, for removal of the stones. The postoperative follow-up for recurrent stones was performed with a cholangiogram and an ultrasonogram, and the quality of life was evaluated by a questionnaire for the symptoms. The mean operating time was 288.3 (150-420) minutes. There was only one postoperative complication, but no intraoperative transfusions or perioperative mortality. Remnant stones were detected in 1 patient on the final T-tube cholangiogram, which was removed by percutaneous choledochoscopy, through the tract matured by the T-tube. There were no cholangitis or recurrent stones during the mean follow-up period of 31.4 (10-45) months. With increasing demand for minimal invasiveness, the laparoscopic treatment of IHD stones could be an effective option.

Laparoscopic management of common bile duct stones

BACKGROUND

While laparoscopic cholecystectomy is widely accepted for therapy of cholecystolithiasis, controversy still exists concerning the management of common bile duct stones. Besides preoperative endoscopic papillotomy followed by laparoscopic cholecystectomy and open common bile duct surgery, management of common bile duct stones can be conducted by laparoscopy, if respective experience is available.

METHOD

During laparoscopic cholecystectomy a cholangiography via the cystic duct is routinely performed. If bile duct stones are detected they are retrieved via the cystic duct or via incision of the common bile duct by insertion of a Fogarty catheter or Dormia basket. Exclusion criteria against simultaneous laparoscopic management include suspicion of malignancy, severe pancreatitis, or cholangitis.

RESULTS

From November 1991 to March 2002, 200 patients primarily underwent laparoscopic therapy of bile duct stones. Retrieval was performed via cystic duct and common bile duct incision in 115 and 85 cases, respectively. Complete removal was achieved in 91%; complication rate and mortality was 7% and 0.5%, respectively. During the same period primary endoscopic papillotomy was necessary in 40 patients because of the above contraindications.

CONCLUSIONS

When correct indications and surgical expertise are observed, simultaneous laparoscopic management of common bile duct stones represents a safe and minimally invasive alternative to a two-procedure approach.

Endoscopic management of common bile duct stones leaving the gallbladder in situ. A cohort study with long-term follow-up

BACKGROUND

Obstructive jaundice caused by stones is a common disorder, mostly managed by endoscopic sphincterotomy followed by cholecystectomy. The aim of this study was to evaluate whether or not clearance of the common bile duct alone is sufficient as treatment for patients with choledocholithiasis.

METHODS

A cohort with 447 patients with symptomatic cholecystocholedocholithiasis, undergoing endoscopic retrograde cholangiography (ERC) and if necessary sphincterotomy (ES). In 164 patients common bile duct stones were proven and treated endoscopically, without performing a subsequent cholecystectomy. All 164 patients were free of symptoms after the endoscopic intervention. This group of patients was compared with 78 patients who underwent cholecystectomy after endoscopic treatment of common bile duct stones. Patients were followed for 1-13 years after ERC and sphincterotomy results and complications were registered.

RESULTS

The ages of the 164 patients in the in situ group were significantly higher than in the cholecystectomy group and the ASA classification (American Society of Anesthesiologists) was significantly higher in the in situ patients. Mean follow-up was 70.9 months. Of the in situ patients 27 (16%) returned with biliary symptoms; 12 with common bile duct stones, three with cholangitis, and one with stenosis of Vater's papilla. Eight patients returned with cholecystitis and 3 with symptomatic cholecystolithiasis. Thirteen patients underwent cholecystectomy and 11 were managed (also) endoscopically. Minor complications were 2 wound infections and 1 bleeding after cholecystectomy. Two patients (1%) died of abdominal sepsis due to cholecystitis. Of the patients who underwent cholecystectomy, 6 (7.6%) returned during follow-up. Three patients had common bile duct stones, 2 had cholangitis and 1 patient presented with papillostenosis. Three patients needed surgical common bile duct exploration and the other 3 were treated endoscopically. After reintervention, cardiopulmonary complications were observed in 1 patient. There was no related death.

CONCLUSION

When common bile duct stones are treated successfully by endoscopic sphincterotomy and patients are free of symptoms, there is no need for routine prophylactic cholecystectomy.
