The association between appendicitis severity and patient age with appendiceal neoplasm histology-a population-based study.

PURPOSE: Recent studies have reported alarming appendiceal tumor rates associated with complicated acute appendicitis, especially in patients presenting with a periappendicular abscess. However, the data on histology of appendiceal tumors among acute appendicitis patients is limited, especially in patient cohorts differentiating between uncomplicated and complicated acute appendicitis. We have previously reported the association of increased appendiceal tumor prevalence with complicated acute appendicitis in this population-based study. The objective of this secondary analysis was to evaluate the association of both appendicitis severity and patient age with appendiceal tumor histology. METHODS: This nationwide population-based registry study (The Finnish Cancer Registry) was conducted from 2007 to 2013. All appendiceal tumors (n = 840) and available medical reports (n = 504) of these patients at eight study hospitals were previously evaluated, identifying altogether 250 patients with both acute appendicitis and appendiceal tumor. RESULTS: The severity of acute appendicitis was significantly associated with more malignant tumor histology. The risk of adenocarcinoma or pseudomyxoma was significantly higher among patients with periappendicular abscess (OR 15.05, CI 95% 6.98-32.49, p < 0.001) and patients presenting with perforated acute appendicitis (OR 4.09, CI 95% 1.69-9.90, p = 0.0018) compared to patients with uncomplicated acute appendicitis. Similarly, patient age over 40 years was significantly associated with the risk of adenocarcinoma and pseudomyxoma (OR 26.46, Cl 95% 7.95-88.09, p < 0.001). Patient sex was not associated with a more malignant appendiceal tumor histology (p = 0.67). CONCLUSION: More malignant appendiceal tumor histology of adenocarcinoma or pseudomyxoma was significantly associated with patient age over 40 years and complicated acute appendicitis, especially periappendicular abscess.

Appendiceal neoplasm risk associated with complicated acute appendicitis-a population based study.

PURPOSE: Appendiceal tumors are rare, but high neoplasm rates have been reported at interval appendectomy after periappendicular abscess. Non-operative management of uncomplicated acute appendicitis has shown promising results. The data on appendiceal tumor incidence and presentation among acute appendicitis patients is limited, especially in patient cohorts differentiating between uncomplicated and complicated acute appendicitis. Objective was to assess appendiceal tumor incidence and tumor association to appendicitis in patients with uncomplicated and complicated acute appendicitis. METHODS: This nationwide population-based registry study was conducted from 2007 to 2013. The Finnish Cancer Registry and the National Institute for Health Registry were used to combine data on all appendiceal tumors and acute appendicitis diagnosis with medical reports evaluated at eight study hospitals. RESULTS: Altogether, 840 appendiceal tumors were identified, and out of these, 504 patient reports were reviewed, including 472 patients in this study. Tumor was diagnosed at appendectomy for suspected acute appendicitis in 276 patients (58%). In the whole study, histologically acute appendicitis and tumor were both present in 53% (n = 250), and out of these, 41% (n = 102) were complicated and 59% (n = 148) uncomplicated acute appendicitis. The associated tumor risk was significantly higher in complicated acute appendicitis compared with uncomplicated cases (3.24% vs. 0.87%, p < 0.001). Overall tumor prevalence among acute appendicitis patients was 1.24%. CONCLUSIONS: Appendiceal tumor prevalence in acute appendicitis was low. Tumor risk was significantly higher in complicated acute appendicitis compared with uncomplicated acute appendicitis. The risk of missed appendiceal tumors related to antibiotic therapy of uncomplicated acute appendicitis is very low.

Patient radiation dose and fluoroscopy time during ERCP: a single-center, retrospective study of influencing factors.

OBJECTIVES: Recently, both the number and the complexity with associated increased technical difficulty of therapeutic ERCP procedures have significantly increased resulting in longer procedural and fluoroscopy times. During ERCP, the patient is exposed to ionizing radiation and the consequent radiation dose depends on multiple factors. The aim of this study was to identify factors affecting fluoroscopy time and radiation dose in patients undergoing ERCP. MATERIALS AND METHODS: Data related to patient demographics, procedural characteristics and radiation exposure in ERCP procedures (n = 638) performed between August 2013 and August 2015 was retrospectively reviewed and analyzed. Statistically significant factors identified by univariate analyses were included in multivariate analysis with fluoroscopy time (FT) and dose area product (DAP) as dependent variables. Effective dose (ED) was estimated from DAP measurements using conversion coefficient. RESULTS: The factors independently associated with increased DAP during ERCP were age, gender, radiographer, complexity level of ERCP, cannulation difficulty grade, bile duct injury and biliary stent placement. In multivariate analysis the endoscopist, the complexity level of ERCP, cannulation difficulty grade, pancreatic duct leakage, bile duct dilatation and brushing were identified as predictors for a longer FT. The mean DAP, FT, number of acquired images and ED for all ERCP procedures were 2.33 Gy·cm2, 1.84 min, 3 and 0.61 mSv, respectively. CONCLUSIONS: Multiple factors had an effect on DAP and FT in ERCP. The awareness of these factors may help to predict possible prolonged procedures causing a higher radiation dose to the patient and thus facilitate the use of appropriate precautions.

Five-Year Follow-up of Antibiotic Therapy for Uncomplicated Acute Appendicitis in the APPAC Randomized Clinical Trial.

Importance: Short-term results support antibiotics as an alternative to surgery for treating uncomplicated acute appendicitis, but long-term outcomes are not known. Objective: To determine the late recurrence rate of appendicitis after antibiotic therapy for the treatment of uncomplicated acute appendicitis. Design, Setting, and Participants: Five-year observational follow-up of patients in the Appendicitis Acuta (APPAC) multicenter randomized clinical trial comparing appendectomy with antibiotic therapy, in which 530 patients aged 18 to 60 years with computed tomography-confirmed uncomplicated acute appendicitis were randomized to undergo an appendectomy (n = 273) or receive antibiotic therapy (n = 257). The initial trial was conducted from November 2009 to June 2012 in Finland; last follow-up was September 6, 2017. This current analysis focused on assessing the 5-year outcomes for the group of patients treated with antibiotics alone. Interventions: Open appendectomy vs antibiotic therapy with intravenous ertapenem for 3 days followed by 7 days of oral levofloxacin and metronidazole. Main Outcomes and Measures: In this analysis, prespecified secondary end points reported at 5-year follow-up included late (after 1 year) appendicitis recurrence after antibiotic treatment, complications, length of hospital stay, and sick leave. Results: Of the 530 patients (201 women; 329 men) enrolled in the trial, 273 patients (median age, 35 years [IQR, 27-46]) were randomized to undergo appendectomy, and 257 (median age, 33 years, [IQR, 26-47]) were randomized to receive antibiotic therapy. In addition to 70 patients who initially received antibiotics but underwent appendectomy within the first year (27.3% [95% CI, 22.0%-33.2%]; 70/256), 30 additional antibiotic-treated patients (16.1% [95% CI, 11.2%-22.2%]; 30/186) underwent appendectomy between 1 and 5 years. The cumulative incidence of appendicitis recurrence was 34.0% (95% CI, 28.2%-40.1%; 87/256) at 2 years, 35.2% (95% CI, 29.3%-41.4%; 90/256) at 3 years, 37.1% (95% CI, 31.2%-43.3%; 95/256) at 4 years, and 39.1% (95% CI, 33.1%-45.3%; 100/256) at 5 years. Of the 85 patients in the antibiotic group who subsequently underwent appendectomy for recurrent appendicitis, 76 had uncomplicated appendicitis, 2 had complicated appendicitis, and 7 did not have appendicitis. At 5 years, the overall complication rate (surgical site infections, incisional hernias, abdominal pain, and obstructive symptoms) was 24.4% (95% CI, 19.2%-30.3%) (n = 60/246) in the appendectomy group and 6.5% (95% CI, 3.8%-10.4%) (n = 16/246) in antibiotic group (P < .001), which calculates to 17.9 percentage points (95% CI, 11.7-24.1) higher after surgery. There was no difference between groups for length of hospital stay, but there was a significant difference in sick leave (11 days more for the appendectomy group). Conclusions and Relevance: Among patients who were initially treated with antibiotics for uncomplicated acute appendicitis, the likelihood of late recurrence within 5 years was 39.1%. This long-term follow-up supports the feasibility of antibiotic treatment alone as an alternative to surgery for uncomplicated acute appendicitis.

Clinical and laboratory findings in the diagnosis of right lower quadrant abdominal pain: outcome analysis of the APPAC trial.

BACKGROUND: The current research on acute appendicitis aims to improve the diagnostics and to clarify to whom antibiotic treatment might be the treatment of choice. METHODS: The present study is a retrospective analysis of a prospectively collected data in our randomized multicenter trial comparing surgery and antibiotic treatment for acute uncomplicated appendicitis (APPAC trial, NCTO1022567). We evaluated 1321 patients with a clinical suspicion of acute appendicitis, who underwent computed tomography (CT). Age, gender, body temperature, pain scores, the duration of symptoms, white blood cell count (WBC) and C-reactive protein (CRP) were recorded on admission. RESULTS: CT confirmed the diagnosis of acute appendicitis in 73% (n=970) and in 27% (n=351) it revealed no or other diagnosis. Acute appendicitis patients had significantly higher WBC levels than patients without appendicitis (median 12.2 and 10.0, respectively, p<0.0001), whereas CRP levels did not differ between the two groups. Ideal cut-off points were assessed with receiver operating characteristic (ROC) curves, but neither these markers or neither their combination nor any clinical characteristic could accurately differentiate between patients with acute appendicitis and those without. The proportion of patients with normal WBC count and CRP was significantly (p=0.0007) lower in patients with acute appendicitis than in patients without appendicitis. CONCLUSIONS: Both clinical findings and laboratory tests are unable to reliably distinguish between patients with acute appendicitis and those without. If both WBC count and CRP are normal, acute appendicitis is very unlikely. The current results emphasize the role of CT imaging in patients with suspected acute appendicitis.

Antibiotic Therapy vs Appendectomy for Treatment of Uncomplicated Acute Appendicitis: The APPAC Randomized Clinical Trial.

IMPORTANCE: An increasing amount of evidence supports the use of antibiotics instead of surgery for treating patients with uncomplicated acute appendicitis. OBJECTIVE: To compare antibiotic therapy with appendectomy in the treatment of uncomplicated acute appendicitis confirmed by computed tomography (CT). DESIGN, SETTING, AND PARTICIPANTS: The Appendicitis Acuta (APPAC) multicenter, open-label, noninferiority randomized clinical trial was conducted from November 2009 until June 2012 in Finland. The trial enrolled 530 patients aged 18 to 60 years with uncomplicated acute appendicitis confirmed by a CT scan. Patients were randomly assigned to early appendectomy or antibiotic treatment with a 1-year follow-up period. INTERVENTIONS: Patients randomized to antibiotic therapy received intravenous ertapenem (1 g/d) for 3 days followed by 7 days of oral levofloxacin (500 mg once daily) and metronidazole (500 mg 3 times per day). Patients randomized to the surgical treatment group were assigned to undergo standard open appendectomy. MAIN OUTCOMES AND MEASURES: The primary end point for the surgical intervention was the successful completion of an appendectomy. The primary end point for antibiotic-treated patients was discharge from the hospital without the need for surgery and no recurrent appendicitis during a 1-year follow-up period. RESULTS: There were 273 patients in the surgical group and 257 in the antibiotic group. Of 273 patients in the surgical group, all but 1 underwent successful appendectomy, resulting in a success rate of 99.6% (95% CI, 98.0% to 100.0%). In the antibiotic group, 70 patients (27.3%; 95% CI, 22.0% to 33.2%) underwent appendectomy within 1 year of initial presentation for appendicitis. Of the 256 patients available for follow-up in the antibiotic group, 186 (72.7%; 95% CI, 66.8% to 78.0%) did not require surgery. The intention-to-treat analysis yielded a difference in treatment efficacy between groups of -27.0% (95% CI, -31.6% to ∞) (P = .89). Given the prespecified noninferiority margin of 24%, we were unable to demonstrate noninferiority of antibiotic treatment relative to surgery. Of the 70 patients randomized to antibiotic treatment who subsequently underwent appendectomy, 58 (82.9%; 95% CI, 72.0% to 90.8%) had uncomplicated appendicitis, 7 (10.0%; 95% CI, 4.1% to 19.5%) had complicated acute appendicitis, and 5 (7.1%; 95% CI, 2.4% to 15.9%) did not have appendicitis but received appendectomy for suspected recurrence. There were no intra-abdominal abscesses or other major complications associated with delayed appendectomy in patients randomized to antibiotic treatment. CONCLUSIONS AND RELEVANCE: Among patients with CT-proven, uncomplicated appendicitis, antibiotic treatment did not meet the prespecified criterion for noninferiority compared with appendectomy. Most patients randomized to antibiotic treatment for uncomplicated appendicitis did not require appendectomy during the 1-year follow-up period, and those who required appendectomy did not experience significant complications.

Elective laparoscopic cholecystectomy for symptomatic uncomplicated gallstone disease: do the symptoms disappear?

BACKGROUND: Symptomatic gallstone disease is considered an indication for cholecystectomy. A considerable proportion of patients may experience persistent symptoms after surgery. The purpose of the present study was to find out the rate of symptom persistence after elective laparoscopic cholecystectomy (LC) performed for symptomatic uncomplicated gallstone disease and, in particular, to clarify whether the recurrence rate differs according to the severity of preoperative symptoms. METHODS: During a 10-year period (1992-2001), 1,101 patients underwent elective LC at Turku City Hospital for Surgery. A questionnaire concerning the intensity of preoperative symptoms, persistence of symptoms postoperatively, and overall satisfaction with the outcome of the procedure was sent to patients. A total of 677 patients [mean age (range) 59 (21-94) years; 554 (83.1%) females] with uncomplicated gallstone disease returned the completed form. RESULTS: Overall, 380 (57%) patients reported attacks of intense upper abdominal pain, and 287 (43%) reported episodic mild abdominal symptoms as the prevailing preoperative symptom. Two hundred and forty-eight (37%) patients continued to have abdominal symptoms after the operation. Among those with predominantly mild abdominal symptoms preoperatively, 119 (41%) reported the persistence of symptoms after the operation, while in the group with mainly severe upper abdominal pain attacks, 129 (33%) patients had recurrences (p = 0.052). CONCLUSIONS: According to our data, more than one-third of patients with symptomatic uncomplicated gallstone disease experienced persistent symptoms after elective LC. Patients with mild preoperative symptoms seemed to have more recurrences than those with severe symptoms, although the difference was not statistically significant.

Angled- or straight-tipped hydrophilic guidewire in biliary cannulation: a prospective, randomized, controlled trial.

BACKGROUND: Deep biliary cannulation is the key for successful endoscopic retrograde cholangiopancreatography (ERCP) procedures. Guidewire-assisted cannulation is associated both with a higher success rate and a reduced risk of post-ERCP pancreatitis compared with standard catheter cannulation. However, to our knowledge there are no prospective, randomized studies comparing the use of different guidewires in biliary cannulation. The goal of this study was to compare the performance of an angled-tipped guidewire (AGW) with a straight-tipped guidewire (SGW) in achieving successful deep biliary cannulation. METHODS: Patients with intended biliary cannulation of an intact papilla were prospectively randomized to angled- or straight-tipped hydrophilic guidewire arms in a tertiary, referral, university hospital setting. Randomized cannulation method was applied either until successful cannulation of the bile duct or until 2 min had passed. Crossover was not included in the study protocol. The main outcome measurements were the cannulation success rate and duration of cannulation. RESULTS: Of the 239 consecutive patients, 155 patients were randomized: in the final analysis 70 patients were included in the AGW arm and 83 patients in the SGW arm. Cannulation time [median; seconds (s)] was shorter with the AGW compared with the SGW (20 vs. 63 s, p = 0.01). There was no difference in the cannulation success rate or the complication rate between the two study groups. CONCLUSIONS: AGW may facilitate biliary cannulation in ERCP.

A prospective randomized controlled multicenter trial comparing antibiotic therapy with appendectomy in the treatment of uncomplicated acute appendicitis (APPAC trial).

BACKGROUND: Although the standard treatment of acute appendicitis (AA) consists of an early appendectomy, there has recently been both an interest and an increase in the use of antibiotic therapy as the primary treatment for uncomplicated AA. However, the use of antibiotic therapy in the treatment of uncomplicated AA is still controversial. METHODS/DESIGN: The APPAC trial is a randomized prospective controlled, open label, non-inferiority multicenter trial designed to compare antibiotic therapy (ertapenem) with emergency appendectomy in the treatment of uncomplicated AA. The primary endpoint of the study is the success of the randomized treatment. In the antibiotic treatment arm successful treatment is defined as being discharged from the hospital without the need for surgical intervention and no recurrent appendicitis during a minimum follow-up of one-year (treatment efficacy). Treatment efficacy in the operative treatment arm is defined as successful appendectomy evaluated to be 100%. Secondary endpoints are post-intervention complications, overall morbidity and mortality, the length of hospital stay and sick leave, treatment costs and pain scores (VAS, visual analoque scale). A maximum of 610 adult patients (aged 18-60 years) with a CT scan confirmed uncomplicated AA will be enrolled from six hospitals and randomized by a closed envelope method in a 1:1 ratio either to undergo emergency appendectomy or to receive ertapenem (1 g per day) for three days continued by oral levofloxacin (500 mg per day) plus metronidazole (1.5 g per day) for seven days. Follow-up by a telephone interview will be at 1 week, 2 months and 1, 3, 5 and 10 years; the primary and secondary endpoints of the trial will be evaluated at each time point. DISCUSSION: The APPAC trial aims to provide level I evidence to support the hypothesis that approximately 75-85% of patients with uncomplicated AA can be treated with effective antibiotic therapy avoiding unnecessary appendectomies and the related operative morbidity, also resulting in major cost savings.

Quality of life after iatrogenic bile duct injury - a case control study.

BACKGROUND: BDIs complicate 0.5 - 0.8% of all LCs even after the learning curve and the limited QoL data on these patients are conflicted. The objective of the current study was to compare the quality of life (QoL) of patients who sustained a bile duct injury (BDI) during laparoscopic cholecystectomy (LC) with a control group who underwent an uneventful LC. METHODS: Sixty-one patients were treated for a BDI during 1995 - 2007 at Turku University Hospital. Fifty-one out of 55 available patients (93 %) were reached and QoL was evaluated by 15D questionnaire. QoL outcome was analyzed both according to the type of injury and the type of treatment and compared with a group with similar age and sex distribution who underwent an uneventful LC during the same time period. RESULTS: With a mean follow-up of eight years (range 2-15 years) there were no major differences in QoL between patients with BDI and patients who underwent an uneventful LC. Depression was the only dimension more frequently seen in the control group (P = 0.011), but this difference was not present in the subgroup analysis or in 15D total scores. CONCLUSIONS: Even at long-term follow-up BDI does not have a major impact on QoL.

Late complications related to palliative stenting in patients with obstructing colorectal cancer.

INTRODUCTION: Self-expanding metal stents (SEMSs) are increasingly used for the palliative treatment of incurable obstructing colorectal cancer. The aim of the current study was to evaluate clinical outcome, including technical and clinical success of stenting, and to identify factors associated with late complications of SEMS in palliation of incurable obstructing colorectal cancer. MATERIAL AND METHODS: Between 2003 and 2010 details of 56 patients who underwent an attempt of SEMS insertion for obstructive incurable colorectal cancer at Turku University Hospital were recorded to our database prospectively and analyzed retrospectively. RESULTS: Technical success was achieved in 42 patients (75%) and clinical success in 39 patients (70%). Late complications related to SEMS occurred in 13 patients (31%). Ten patients (24%) needed re-intervention because of a complication: Eight ostomies, one Hartmann´s procedure due to late perforation and one re-stenting because of stent migration. Three patients with stent-related complications were treated conservatively. Chemotherapy and prolonged survival were risk factors for SEMS-related late complications and re-intervention. CONCLUSION: SEMS insertion is a feasible procedure for the palliative treatment of obstructing colorectal cancer in patients with severe comorbidities and short life expectancy. However, for patients who are candidates for chemotherapy and have a longer life expectancy, other treatment options such as palliative tumor resection should also be considered.

Female gender and post-ERCP pancreatitis: is the association caused by difficult cannulation?

OBJECTIVE: Female gender is a well-known risk factor for the development of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis, but the underlying mechanism for this increased risk has remained unknown. We hypothesize that cannulation difficulty might play a part in this association. The aim of the current study was to determine whether the female papilla is more difficult to cannulate than the male papilla. MATERIAL AND METHODS: Prospective data collection with emphasis on cannulation was conducted in 364 consecutive biliary ERCP procedures performed by very experienced ERCP endoscopists through native papilla in a tertiary referral university hospital. RESULTS: Although the cannulation times seemed to be longer and alternative cannulation techniques seemed to be needed more frequently for successful cannulation in female than male patients, no statistically significant differences (p = 0.061 and 0.054, respectively) in the cannulation process could be found between the genders. CONCLUSIONS: The study was not able to confirm that the cannulation of the female papilla is more troublesome than the cannulation of the male papilla.

Bile duct injuries during open and laparoscopic cholecystectomy in the laparoscopic era: alarming trends.

BACKGROUND: After the introduction of laparoscopic cholecystectomy (LC), scientific discussion and concern about iatrogenic bile duct injuries (BDIs) have been limited mostly to BDIs sustained in LC, while BDIs sustained in open cholecystectomy (OC) and in all cholecystectomies have not been the center of attention. METHODS: This study included all patients who sustained BDI in OC or LC in southwest Finland between 1997 and 2007. All data were collected retrospectively in June 2009. RESULTS: Altogether 75 BDIs were encountered in a total of 8349 cholecystectomies, for an overall incidence of 0.90%. Twenty BDIs (15 Amsterdam type A and 5 type B, C, or D) occurred in the 1616 OCs (incidence rate = 1.24%), and 55 (26 type A and 29 type B, C, or D) in the 6733 LCs (incidence rate = 0.82%). All the BDIs in the OCs were missed while 11/29 of the major BDIs in the LCs were detected at the time of surgery. Fifty-four of 59 type A, B, and C BDIs could be treated endoscopically. CONCLUSIONS: In the laparoscopic era, OC is associated with a high number of BDIs, if minor BDIs are included. Excluding some major LC BDIs, BDIs are, as a rule, missed at the time of surgery. More than 90% of Amsterdam types A, B, and C BDIs can be treated endoscopically, whereas type D BDI remains an absolute indication for surgery.

Double-guidewire-assisted biliary cannulation: experiences from a single tertiary referral center.

BACKGROUND: Even in experienced hands, a common problem with endoscopic retrograde cholangiopancreatography (ERCP) is difficulty reaching a deep biliary cannulation. The most recent alternative method for difficult biliary cannulation is the double-guidewire technique. The current prospective study aimed to clarify the feasibility and safety of the double-guidewire-assisted biliary cannulation at the authors' institution. METHODS: All consecutive patients (n=284) admitted for biliary ERCP during 2009 who had unhindered access to a native papilla were included in the study. The application and success rates of the double-guidewire method for deep biliary cannulation and the complications of ERCP procedures using the double-guidewire technique were determined. The overall success rate for biliary cannulation in these cases also was determined, and the times from the first touch to the papilla to deep biliary cannulation and for the entire ERCP procedure were recorded. RESULTS: The double-guidewire-assisted cannulation technique was applied in 18% (50/284) of ERCPs with a success rate of 66% (33/50). In these 50 cases, the overall success rate for biliary cannulation was 98% (49/50). The median cannulation time was 8 min, and the median duration of the entire ERCP procedure was 20 min. The rate of post-ERCP pancreatitis was 2% (1/50). CONCLUSIONS: The double-guidewire technique is a feasible and safe method for difficult biliary cannulation with low rate of post-ERCP pancreatitis. However, it seems important to proceed to alternative cannulation techniques if the double-guidewire technique appears troublesome.

Elective laparoscopic cholecystectomy: the effect of age on conversions, complications and long-term results.

BACKGROUND/AIMS: The purpose of the present study was to analyze the appropriateness and long-term results of elective laparoscopic cholecystectomy in the treatment of gallstone disease in the elderly. METHODS: We studied all elderly (≥75 years) patients (n = 80) who underwent laparoscopic cholecystectomy at our institution during the years 1992-2001. Two control groups (65-74 years and <65 years) included the same amount of patients. For determining the long-term results, we asked the patients to specify their overall satisfaction with the results of the procedure (very satisfied, satisfied, no effect, worse). RESULTS: There were no statistically significant differences in mean operative time (61, 65, 72 min) or conversions to open surgery (6, 11, 16%) between the age groups (<65, 65-74, ≥75 years). The mean hospitalization time (2.1, 3.3, 4.4 days) and complications (0, 11, 13%) increased with the age of the patients. Neither severe complications nor mortality were encountered. The vast majority of the patients were very satisfied or satisfied with the long-term results of the procedure in all age groups (97% <65 years, 83% 65-74 years, 80% ≥75 years). CONCLUSION: Elective laparoscopic cholecystectomy is also a safe and feasible operation with good long-term results in the elderly.

Clinical success of ERCP procedures in nonagenarian patients with bile duct stones.

In the general population, endoscopic retrograde cholangiopancreatography (ERCP) procedures are the gold standard in the treatment of bile duct stones. However, repeat endoscopic procedures and sometimes even open surgery are needed in difficult cases with retaining bile duct stones. The aim of the present study was to determine the clinical success of ERCP procedures in the treatment of bile duct stones in extremely old patients. A retrospective data review comprising prospective data collection and double-entry bookkeeping of 23 therapeutic ERCPs in 20 nonagenarians with bile duct stones was conducted between 1997 and 2007. The primary ERCP procedure was the definitive treatment in 17 out of 20 patients with bile duct stones, giving a clinical success rate of 85 % for the first endoscopic procedure. In the remaining three patients, a repeat ERCP procedure had to be done in the follow-up. After these three repeat procedures with successful outcome, the clinical success of endoscopic treatment was 100%. There was no further recurrent biliary obstruction in any of the patients prior to death which occurred after a mean of 38 months (two patients are still alive), and no open surgery had to be performed in these patients. To be concluded, endoscopic treatment modality seems to be excellent in extremely elderly patients with bile duct stones.

Clinical suspicion of acute appendicitis - is the time ripe for more conservative treatment?

Traditionally, the diagnosis of acute appendicitis has been based mainly on a history compatible with acute appendicitis and pain at McBurney's point, and the treatment of choice in patients with right iliac fossa pain referring to acute appendicitis has been (laparoscopic) appendicectomy. In too many centers where these traditional rules are followed the accuracy of diagnosis of acute appendicitis still remains at the level of 80 to 85%. It is time to re-evaluate these general guidelines. Here, I face the issue from a few points of view the clinical value of which has not been extensively discussed in the literature but that in my opinion markedly improve the diagnostic accuracy and treatment of patients with right iliac fossa pain. Although there is a clinical suspicion of acute appendicitis, it can be excluded in adult patient, if both leucocyte count and C-reactive protein value are normal on admission to hospital and remain normal in the follow-up. In expert centers, up to 100% sensitivity and specificity have been reported for contrast-enhanced multidetector computed tomography in the diagnosis of acute appendicitis. Antibiotic treatment can be considered a safe first-line therapy in selected patients with acute appendicitis.
