Abstract
BACKGROUND Laparoscopic cholecystectomy (LapC) is one of the most frequently performed surgical procedures worldwide. Reaching technical competency in performing LapC is considered one essential task for young surgeons. Investigating the learning curve for LapC (LC-LapC) may provide important information regarding the learning process and guide the training pathway of residents, improving educational outcomes. The present study aimed to investigate LC-LapC among general surgery residents (GSRs). METHODS Operative surgical reports of consecutive patients undergoing LapC performed by GSRs attending the General Surgery Residency Program at the University of Milan were analysed. Data on patient- and surgery-related variables were obtained from the ICD-9-CM diagnosis codes and gathered. A multidimensional assessment of the LC was performed through Cumulative Sum (CUSUM) and Risk-Adjusted (RA)-CUSUM analysis. RESULTS 340 patients operated by 6 GSRs were collected. The CUSUM and RA-CUSUM graphs based on surgical failures allowed to distinguish two defined phases for all GSRs: an initial phase ending at the peak, so-called learning phase, followed by a phase in which there was a significant decrease in failure incidence, so-called proficiency phase. The learning phase was completed for all GSRs at most within 25 procedures, but the trend of the curves and the number of procedures needed to achieve technical competency varied among operators ranging between 7 and 25. CONCLUSIONS The present study suggested that at most 25 procedures might be sufficient to acquire technical competency in LapC. The variability in the number of procedures needed to complete the LC, ranging between 7 and 25, could be due to the heterogeneous scenarios in which LapC was performed, and deserves to be investigated through a prospective study involving a larger number of GSRs and institutions.

Abstract
BACKGROUND The 'golden 72 hours' rule from the onset of symptoms still applies in laparoscopic cholecystectomy for acute cholecystitis. This rule has been discussed with increasing experience in laparoscopic surgery in recent years. OBJECTIVE This study aims to determine the optimal symptom duration based on the surgeon's volume when deciding on early laparoscopic cholecystectomy for acute cholecystitis. MATERIALS AND METHODS The patients were categorized into two groups: Group 1 (≤3 days) and Group 2 (>3 days) based on the symptom duration, and high-volume surgeons (performing >100 laparoscopic cholecystectomies in a year) and low-volume surgeons (performing <100 laparoscopic cholecystectomies in a year) based on the surgeon volume. All surgeons had received advanced training in laparoscopic surgery. RESULTS There was no statistical difference in postoperative outcomes between groups, except for a few data (p>0.05). The operative time was longer in Group 2, the postoperative hospital stay was longer for low-volume surgeons than for high-volume surgeons after three days, and operative time was longer after three days than the first three days in low-volume surgeons (p<0.05). CONCLUSIONS Early laparoscopic cholecystectomy may be recommended for acute cholecystitis with symptom duration of more than three days, regardless of the surgeon volume, as long as they are competent in laparoscopic surgeries.

Abstract
BACKGROUND High surgical volumes are attributed to improved quality of care, especially for extensive procedures. However, it remains unknown whether high-volume surgeons and hospitals have better results in gallstone surgery. The aim of this study was to investigate whether operative volume affects outcomes in cholecystectomies. METHODS A registry-based cohort study was performed, based on the Swedish Registry of Gallstone Surgery. Cholecystectomies from 2006 to 2019 were included. Annual volumes for the surgeon and hospital were retrieved. All procedures were categorized into volume-based quartiles, with the highest group as reference. Low volume was defined as fewer than 20 operations per surgeon per year and fewer than 211 cholecystectomies per hospital per year. Differences in outcomes were analysed separately for elective and acute procedures. RESULTS The analysis included 154 934 cholecystectomies. Of these, 101 221 (65.3 per cent) were elective and 53 713 (34.7 per cent) were acute procedures. Surgeons with low volumes had longer operating times (P < 0.001) and higher conversion rates in elective (OR 1.35; P = 0.023) and acute (OR 2.41; P < 0.001) operations. Low-volume surgeons also caused more bile duct injuries (OR 1.41; P = 0.033) and surgical complications (OR 1.15; P = 0.033) in elective surgery, but the results were not statistically significant for acute procedures. Low-volume hospitals had more bile duct injuries in both elective (OR 1.75; P = 0.002) and acute (OR 1.96; P = 0.003) operations, and a higher mortality rate after acute surgery (OR 2.53; P = 0.007). CONCLUSION This study has demonstrated that operative volumes influence outcomes in cholecystectomy. The results indicate that gallstone surgery should be performed by procedure-dedicated surgeons at hospitals with high volumes of this type of benign surgery.

Abstract
Zusammenfassung
Einleitung Bei komplexeren chirurgischen Eingriffen wie der Kolonresektion, herzchirurgischen Eingriffen, arteriellen Rekonstruktionen oder Leberresektionen ist der Einfluss des
Chirurgen auf die postoperative Morbidität nachgewiesen. Bei Routineeingriffen wie der Cholezystektomie liegen bislang keine Erkenntnisse zum Zusammenhang von Operateur und Morbidität vor.
Insbesondere Untersuchungen bei erfahrenen Chirurgen fehlen.
Methoden Es wurden 710 konsekutive Patienten, die zwischen Januar 2014 und Dezember 2018 von erfahrenen Chirurgen (über n = 300 Cholezystektomien vor Beginn der Untersuchung, über 5
Jahre nach bestandener Facharztprüfung) cholezystektomiert wurden, untersucht. In einer univariaten Analyse wurde der Einfluss von Patientenmerkmalen, Laborparametern, chirurgischen
Parametern und des Operateurs auf die postoperative Morbidität analysiert. Die Variablen mit statistischer Signifikanzen wurden dann einer multivariaten logistischen Regressionsanalyse
unterzogen.
Ergebnisse Die Mortalität lag bei 5 von 710 (0,7%), die Morbidität bei 58 von 710 (8,2%). 37 von 710 Patienten erlitten eine chirurgische Komplikation, 21 von 710 Patienten eine
nicht chirurgische Komplikation. Hinsichtlich der Gesamtmorbidität waren in multivariater Analyse der Kreatininwert (OR 1,29; KI 1,01–1,648; p = 0,042), GOT (OR 1,0405; KI 1–1,01; p = 0,03),
offene und Konversions-Cholezystektomie (OR 4,134; KI 1,587–10,768; p = 0,004) und der individuelle Chirurg (OR bis 40,675; p = 0,001) ein unabhängiger Risikofaktor. Bei Analyse der
chirurgischen Komplikationen blieben offene und Konversions-Cholezystektomie (OR 8,104; KI 3,03–21,68; p < 0,001) sowie der individuelle Chirurg (OR bis 79,69; p = 0,005) ein statistisch
signifikanter unabhängiger Risikofaktor.
Schlussfolgerung Der individuelle Chirurg ist auch bei einem Routineeingriff wie der Cholezystektomie ein unabhängiger Risikofaktor für die Morbidität. Dies gilt auch für erfahrene
Chirurgen mit Facharztstatus und hoher Caseload. Im Hinblick auf die Patientensicherheit und Verbesserungen der Ergebnisqualität muss daher diskutiert werden, ob eine routinemäßige
risikoadjustierte Messung der individuellen Ergebnisse eines jeden Chirurgen als Basis eines gezielten Qualifizierungprogramms sinnvoll ist.

The effect of surgical strategy in difficult cholecystectomy cases on postoperative complications outcome: a value-based healthcare comparative study. Surg Endosc 2022; 36:5293-5302. [PMID: 35000001 DOI: 10.1007/s00464-021-08907-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 11/21/2021] [Indexed: 01/17/2023]
Abstract
BACKGROUND In patients undergoing laparoscopic cholecystectomy (LC) for complicated biliary disease, complication rates increase up to 30%. The aim of this study is to assess the effect of differences in surgical strategy comparing outcome data of two large volume hospitals. METHODS A prospective database was created for all the patients who underwent a LC in two large volume hospitals between January 2017 and December 2018. In cases of difficult cholecystectomy in clinic A, regular LC or conversion were surgical strategies. In clinic B, laparoscopic subtotal cholecystectomy was performed as an alternative in difficult cases. The difficulty of the cholecystectomy (score 1-4) and surgical strategy (regular LC, subtotal cholecystectomy, conversion) were scored. Postoperative complications, reinterventions, and ICU admission were assessed. For predicting adverse postoperative complication outcomes, uni- and multivariable analyses were used. RESULTS A total of 2104 patients underwent a LC in the study period of which 974 were from clinic A and 1130 were from clinic B. In total, 368 procedures (17%) were scored as a difficult cholecystectomy. In clinic A, more conversions were performed (4.4%) compared to clinic B (1.0%; p < 0.001). In clinic B, more subtotal laparoscopic cholecystectomies were performed (1.8%) compared to clinic A (0%; p = < 0.001). Overall complication rate was 8.2% for clinic A and 10.2% for clinic B (p = 0.121). Postoperative complication rates per group for regular LC, conversion, and subtotal cholecystectomy in difficult cholecystectomies were 45 (15%), 12 (24%), and 7 (35%; p = 0.035), respectively. The strongest predictor for Clavien-Dindo grade 3-5 complication was subtotal cholecystectomy. CONCLUSION Surgical strategy in case of a difficult cholecystectomy seems to have an important impact on postoperative complication outcome. The effect of a subtotal cholecystectomy on complications is of great concern.

Abstract
BACKGROUND Laparoscopic cholecystectomies continue to pose trouble for surgeons in the face of severe inflammation. In the advent of inability to perform an adequate dissection, a "bailout cholecystectomy" is advocated. Conversion to open or subtotal cholecystectomy is among the standard bailout procedures in such instances. METHODS We performed a retrospective single institution review from January 2016 to August 2019. All patients who underwent a cholecystectomy were included, while those with a concurrent operation, malignancy, planned as an open cholecystectomy, or performed by a low volume surgeon were excluded. Patient characteristics, operative reports, and outcomes were collected, as were surgeon characteristics such as years of experience, case volume, and bailout rate. Univariable and multivariable analysis were performed. RESULTS 2458 (92.6%) underwent laparoscopic total cholecystectomy (LTC) and 196 (7.4%) underwent a bailout cholecystectomy (BOC). BOC patients tended to be older (p < 0.001), male (p < 0.001), have a longer duration of symptoms (p < 0.001), and higher ASA class (p < 0.001). They also had more signs of biliary inflammation, as evidenced by increased leukocytosis (p < 0.001), tachycardia (p < 0.001), bilirubinemia (p = 0.003), common bile duct dilation (p < 0.001), and gallbladder wall thickening (p < 0.001). The BOC cohort also had increased rates of complications, including bile leak (16%, p < 0.001), retained stone (5.1%, p = 0.005), operative time (114 min vs 79 min, p < 0.001), and secondary interventions (22.7%, p < 0.001). Male gender (aOR = 2.8, p < 0.001), preoperative diagnosis of acute cholecystitis (aOR = 2.2, p = 0.032), right upper quadrant tenderness (aOR = 3.0, p = 0.008), Asian race (aOR = 2.7, p = 0.014), and intraoperative adhesions (aOR = 13.0, p < 0.001) were found to carry independent risk for BOC. Surgeon bailout rate ≥ 7% was also found to be an independent risk factor for conversion to BOC. CONCLUSIONS Male gender, signs of biliary inflammation (tachycardia, leukocytosis, dilated CBD, and diagnosis of acute cholecystitis), as well as surgeon bailout rate of 7% were independent risk factors for BOC.

Abstract
BACKGROUND The relationship between institutional liver transplantation (LT) case volume and clinical outcomes after liver re-transplantation is yet to be determined. METHODS Patients who underwent liver re-transplantation between 2007 and 2016 were selected from the Korean National Healthcare Insurance Service database. Liver transplant centers were categorized to either high-volume centers (≥ 64 LTs/year) or low-volume centers (< 64 LTs/year) according to the annual LT case volume. In-hospital and long-term mortality after liver re-transplantation were compared. RESULTS A total of 258 liver re-transplantations were performed during the study period: 175 liver re-transplantations were performed in 3 high-volume centers and 83 were performed in 21 low-volume centers. In-hospital mortality after liver re-transplantation in high and low-volume centers were 25% and 36% (P = 0.069), respectively. Adjusted in-hospital mortality was not different between low and high-volume centers. Adjusted 1-year mortality was significantly higher in low-volume centers (OR 2.14, 95% CI 1.05-4.37, P = 0.037) compared to high-volume centers. Long-term survival for up to 9 years was also superior in high-volume centers (P = 0.005). Other risk factors of in-hospital mortality and 1-year mortality included female sex and higher Elixhauser comorbidity index. CONCLUSION Centers with higher case volume (≥ 64 LTs/year) showed lower in-hospital and overall mortality after liver re-transplantation compared to low-volume centers.

Abstract
Background Recent advances in esophageal cancer treatment require a reevaluation of the relationship between institutional case‐volume and patient outcome. The aim of this study was to analyze and update the association between surgical case‐volume and both in‐hospital and long‐term mortality after esophagectomy for esophageal cancer. Methods Data of all adult patients who received esophageal cancer surgery in Korea between 2004 and 2017 were extracted from the database of the National Health Insurance Service. Hospitals were categorized into three groups according to the average annual number of esophageal cancer surgery: low‐volume (<12 cases/year), medium‐volume (12–48 cases/year), and high‐volume centers (>48 cases/year). Postoperative in‐hospital and 1‐, 3‐, and 5‐year mortality were analyzed according to the categorized groups using logistic regression. Results In total, 11, 346 esophageal cancer surgeries in 122 hospitals were analyzed. In‐hospital mortality in the high‐, medium‐, and low‐volume centers were 3.4%, 6.4%, and 11.1%, respectively. In‐hospital mortality was significantly higher in low‐ volume (adjusted odds ratio, 3.91; confidence interval, 3.18–4.80; p < 0.001) and medium volume (adjusted odds ratio, 2.21; confidence interval, 1.80–2.74, p < 0.001) centers compared to high‐volume centers. Patients who received esophageal cancer surgery in a low‐or medium‐volume center also had higher 1‐, 3‐, and 5‐year mortality compared to patients who received the surgery in a high‐volume center. Conclusions Centers with lower case‐volume showed higher in‐hospital mortality and long‐term mortality after esophageal cancer surgery.

Abstract
Background Our aim is to determine the relationships among patient demographics, patient history, surgical experience, and conversion rate (CR) during elective laparoscopic cholecystectomies (LCs). Methods We analyzed data from patients who underwent LC surgery between 2005 and 2014 based on patient charts and electronic documentation. CR (%) was evaluated in 4013 patients who underwent elective LC surgery. The relationships between certain predictive factors (patient demographics, endoscopic retrograde cholangiopancreatography (ERCP), acute cholecystitis (AC), abdominal surgery in the patient history, as well as surgical experience) and CR were examined by univariate analysis and logistic regression. Results In our sample (N = 4013), the CR was 4.2%. The CR was twice as frequent among males than among females (6.8 vs. 3.2%, p < 0.001), and the chance of conversion increased from 3.4 to 5.9% in patients older than 65 years. The detected CR was 8.8% in a group of patients who underwent previous ERCP (8.8 vs. 3.5%, p < 0.001). From the ERCP indications, most often, conversion was performed because of severe biliary tract obstruction (CR: 9.3%). LC had to be converted to open surgery after upper and lower abdominal surgeries in 18.8 and 4.8% cases, respectively. Both AC and ERCP in the patient history raised the CR (12.3%, p < 0.001 and 8.8%, p < 0.001). More surgical experience and high surgery volume were not associated with a lower CR prevalence. Conclusions Patient demographics (male gender and age > 65 years), previous ERCP, and upper abdominal surgery or history of AC affected the likelihood of conversion. More surgical experience and high surgery volume were not associated with a lower CR prevalence.

Abstract
Aims Hospital case volume is shown to be associated with postoperative outcomes in various types of surgery. However, conflicting results of volume-outcome relationship have been reported in hip fracture surgery. This retrospective cohort study aimed to evaluate the association between hospital case volume and postoperative outcomes in patients who had hip fracture surgery. We hypothesized that higher case volume would be associated with lower risk of in-hospital and one-year mortality after hip fracture surgery. Methods Data for all patients who underwent surgery for hip fracture from January 2008 to December 2016 were extracted from the Korean National Healthcare Insurance Service database. According to mean annual case volume of surgery for hip fracture, hospitals were classified into very low (< 30 cases/year), low (30 to 50 cases/year), intermediate (50 to 100 cases/year), high (100 to 150 cases/year), or very high (> 150 cases/year) groups. The association between hospital case volume and in-hospital mortality or one-year mortality was assessed using the logistic regression model to adjust for age, sex, type of fracture, type of anaesthesia, transfusion, comorbidities, and year of surgery. Results Between January 2008 and December 2016, 269,535 patients underwent hip fracture surgery in 1,567 hospitals in Korea. Compared to hospitals with very high volume, in-hospital mortality rates were significantly higher in those with high volume (odds ratio (OR) 1.10, 95% confidence interval ((CI) 1.02 to 1.17, p = 0.011), low volume (OR 1.22, 95% CI 1.14 to 1.32, p < 0.001), and very low volume (OR 1.25, 95% CI 1.16 to 1.34, p < 0.001). Similarly, hospitals with lower case volume showed higher one-year mortality rates compared to hospitals with very high case volume (low volume group, OR 1.15, 95% CI 1.11 to 1.19, p < 0.001; very low volume group, OR 1.10, 95% CI 1.07 to 1.14, p < 0.001). Conclusion Higher hospital case volume of hip fracture surgery was associated with lower in-hospital mortality and one-year mortality in a dose-response fashion.

Abstract
BACKGROUND This study investigated how annual caseloads and the surgeon's previous experience influence the outcome in laparoscopic cholecystectomy (LCC) for acute cholecystitis. METHODS A total of 892 patients treated in Helsinki University Hospital in 2013-2016 were retrospectively analyzed. Surgeons were compared regarding volume-over 5 LCCs for acute cholecystitis a year versus 5 or fewer LCCs a year, and experience-attendings versus residents. RESULTS High-volume surgeons (n=14) operated faster than low-volume surgeons (n=62) (91 vs. 108 min, P<0.001). Examining only procedures with an attending present, high-volume attendings (n=7) converted less (14.9% vs. 32.0%, P<0.001) and operated faster (95 vs. 110 min, P<0.001) compared with low-volume attendings (n=41). The results of residents did not significantly differ from the results of attendings. CONCLUSIONS Attending surgeons, performing >5 LCCs for acute cholecystitis a year, have shorter operative times and lower conversion rates.

Bile leakage after loop closure vs clip closure of the cystic duct during laparoscopic cholecystectomy: A retrospective analysis of a prospective cohort. World J Gastrointest Surg 2020; 12:9-16. [PMID: 31984120 PMCID: PMC6943090 DOI: 10.4240/wjgs.v12.i1.9] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2019] [Revised: 10/19/2019] [Accepted: 11/21/2019] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is one of the most frequently performed surgical procedures. Cystic stump leakage is an underestimated, potentially life threatening complication that occurs in 1%-6% of the patients. With a secure cystic duct occlusion technique during LC, bile leakage becomes a preventable complication.
AIM To investigate the effect of polydioxanone (PDS) loop closure of the cystic duct on bile leakage rate in LC patients.
METHODS In this retrospective analysis of a prospective cohort, the effect of PDS loop closure of the cystic duct on bile leakage complication was compared to patients with conventional clip closure. Logistic regression analysis was used to develop a risk score to identify bile leakage risk. Leakage rate was assessed for categories of patients with increasing levels of bile leakage risk.
RESULTS Of the 4359 patients who underwent LC, 136 (3%) underwent cystic duct closure by a PDS loop. Preoperatively, loop closure patients had significantly more complicated biliary disease compared to the clipped closure patients. In the loop closure cohort, zero (0%) bile leakage occurred compared to 59 of 4223 (1.4%) clip closure patients. For patients at increased bile leakage risk (risk score ≥ 1) rates were 1.6% and up to 13% (4/30) for clip closure patients with a risk score ≥ 4. This risk increase paralleled a stepwise increase of actual bile leakage complication for clip closure patients, which was not observed for loop closure patients.
CONCLUSION Cystic duct closure with a PDS loop during LC may reduce bile leakage in patients at increased risk for bile leakage.

Abstract
BACKGROUND The relationship between institutional case volume and clinical outcomes after living donor liver transplantation is not clarified. METHODS We conducted a nationwide retrospective cohort study using the database of Korean National Healthcare Insurance Service. Between January 2007 and December 2016, 7073 adult living donor liver transplantations were performed at 50 centers in Korea. Centers were categorized according to the average annual number of liver transplantations: >50, 10 to 50, and <10. RESULTS In-hospital mortality rates in the high-, medium-, and low-volume centers were 2.8%, 4.1%, and 6.7%, respectively. After adjustment, in-hospital mortality was significantly higher in low-volume centers (adjusted odds ratio, 2.287; 95% confidence interval, 1.471-3.557; P < 0.001) and medium-volume centers (adjusted odds ratio, 1.676; 95% confidence interval, 1.089-2.578; P = 0.019) compared with high-volume centers. Long-term survival for up to 9 years was better, and intensive care unit and hospital length of stay were shorter in high-volume centers. CONCLUSIONS Centers with higher case volume (>50 liver transplantations/year) had better outcomes after living donor liver transplantation, including in-hospital mortality and long-term mortality compared with centers with lower case volume (≤50 liver transplantations/year).

Abstract
In the last decade, emergency general surgery (EGS) in Australia and New Zealand has seen a transition from the traditional on-call system to the acute surgical unit (ASU) model. The importance and growing demand for EGS has resulted in the implementation of the General Surgeons Australia's 12-point plan for emergency surgery. Since its release, the 12-point plan has been used as a benchmark of a well-functioning ASU, both locally and abroad. This study aims to provide a descriptive review on the relevance of the 12-point plan to the ASU model and review the current evidence to support this framework. The review concludes that the establishment of the ASU model has met the aims set out by the Royal Australasian College of Surgeons for EGS. The 12-point plan is relevant and has good evidence to support its framework.

Abstract
BACKGROUND Although there is a large body of published data demonstrating improved outcomes for complex operations when performed by high-volume surgeons at high-volume hospitals, the literature is mixed regarding whether this same relationship applies in less complex and more common surgeries such as laparoscopic cholecystectomy. METHODS This study utilized the New York State Department of Health Statewide Planning and Research Cooperative System database to identify patients undergoing laparoscopic cholecystectomy for acute and chronic biliary pathology. Rates of perioperative outcomes were compared among 4 distinct categories of surgeons based on surgeon annual and cumulative volume: low cumulative/low annual, low cumulative/high annual, high cumulative/low annual, and high cumulative/high annual. RESULTS A total of 150,938 patients undergoing operation by 3,306 surgeons at 250 hospitals across New York state were included for analysis from 2000-2014. There was no difference in adjusted 30-day in-hospital mortality, major events, procedural complications, bile duct injury, or reintervention rates between the 4 groups of surgeons. However, patients undergoing operation by high cumulative/high annual volume surgeons were less likely to experience 30-day readmission, prolonged duration of stay, and high charges when compared with low cumulative/low annual volume surgeons. CONCLUSION In New York state, increased surgeon annual and cumulative volume predicts lower rates of 30-day readmission, prolonged duration of stay, and high charges in laparoscopic cholecystectomy, but has no effect on in-hospital mortality, major events, bile duct injury, procedural complications, or reintervention. There is no evidence to support regionalization of this procedure as operative outcomes are comparable even in less experienced hands.

Abstract
The aim of this study was to assess whether the case volume of surgeons and hospitals affects the rates of postoperative complications and survival after liver transplantation. This population-based retrospective cohort study included 2938 recipients of liver transplantation performed between 1998 and 2012, enrolled from the Taiwan National Health Insurance Research Database. They were divided into two groups, according to the cumulative case volume of their operating surgeons and the case volume of their hospitals. The duration of intensive care unit stay and post-transplantation hospitalization, postoperative complications, and mortality were analyzed. The results showed that, in the low and high case volume surgeons groups, respectively, acute renal failure occurred at the rate of 14.11% and 5.86% (p<0.0001), and the overall mortality rates were 19.61% and 12.44% (p<0.0001). In the low and high case volume hospital groups, respectively, acute renal failure occurred in 11% and 7.11% of the recipients (p = 0.0004), and the overall mortality was 18.44% and 12.86% (p<0.0001). These findings suggest that liver transplantation recipients operated on higher case volume surgeons or in higher case volume hospitals have a lower rate of acute renal failure and mortality.

Abstract
BACKGROUND Complication rates after a laparoscopic cholecystectomy are still up to 10 %. Knowledge of individual patient risk profiles could help to reduce morbidity. AIM The aim of this study is to create risk profiles for specific complications to anticipate on individual outcome. PATIENTS AND METHODS Individual patient outcome for a specific post-operative complication was assessed from a retrospective database of two major teaching hospitals, using uni- and multivariable analyses. RESULTS A total of 4359 patients were included of which 346 developed one or more complications (8 %). Five risk profiles were found to predict specific complications: older patients (>65 year) are at risk for pneumonia (OR 7.0, 95 % CI 3.3-15.0, p < 0.001) and bleeding (OR 2.2, 95 % CI 1.2-3.9, p = 0.014), patients with acute cholecystitis are at risk for intra-abdominal abscess (OR 5.9, 95 % CI 3.4-10.1, p < 0.001), bile leakage (OR 3.6, 95 % CI 2.0-6.6, p < 0.001) and pneumonia (OR 3.5, 95 % CI 1.6-7.6, p < 0.002), previous history of cholecystitis is predictive for wound infection (OR 5.1, 95 % CI, (2.7-9.7), p < 0.001), intra-abdominal abscess (OR 6.1, 95 % CI 2.8-13.8, p < 0.001), post-operative bleeding (OR 4.8, 95 % CI 2.1-11.1, p < 0.001), bile leakage (OR 7.2, 95 % CI 3.4-15.4, p < 0.001) and pneumonia (OR 3.9, 95 % CI 1.3-11.9, p = 0.018), pre-operative ERCP is predictive for intra-abdominal abscess (OR 3.3, 95 % CI 2.0-5.7, p < 0.001), post-operative bleeding (OR 2.1, 95 % CI 1.2-3.9, p = 0.058) and pneumonia (OR 3.8, 95 % CI 1.9-7.8, p = 0.001), and converted patients are at risk for wound infection (OR 4.0, 95 % CI 2.1-7.7, p < 0.001) and intra-abdominal abscess (OR 3.5, 95 % CI 1.6-7.7, p = 0.002). CONCLUSION Individual risk prediction of outcome after laparoscopic cholecystectomy is feasible. This facilitates individual pre-operative doctor-patient communication and may tailor surgical strategies.

Abstract
Cholecystectomy is one of the most commonly performed surgical procedures in the United States. A common complication is dropped gallstones, and the diversity of their presentation poses a substantial diagnostic challenge. We report the case of a 58-year-old man presenting with chronic right upper quadrant hours status post cholecystectomy. Imaging demonstrated retained gallstones in the perihepatic space and symptoms remitted following their removal via laparoscopic operation. Gallstones are lost in roughly 1 in 40 cholecystectomies and are usually asymptomatic. The most common presentations are months or years status post cholecystectomy due to fistula, abscess, or sinus tract formation. We report this case hoping to bring light to a rare presentation for dropped gallstones and provide advice on the management of this common complication of cholecystectomy.
