RESUMO
BACKGROUND/OBJECTIVES: Pancreatic surgery may have a long-lasting effect on patients' health status and quality of life (QoL). We aim to evaluate patient-reported outcomes (PRO) 3 months after pancreatic surgery. METHODS: Patients scheduled for pancreatic surgery were enrolled in a prospective trial at five German centers. Patients completed PRO questionnaires (EQ-5D-5L, EORTC QLQ-PAN26, patient-reported happiness, and HADS-D), we report the first follow-up 3 months after surgery as an interim analysis. Statistical testing was performed using R software. RESULTS: From 2019 to 2022 203 patients were enrolled, a three-month follow-up questionnaire was available in 135 (65.5 %). 77 (57.9 %) underwent surgery for malignant disease. Patient-reported health status (EQ-5D-5L) was impaired in 4/5 dimensions (mobility, self-care, usual activities, pain, discomfort) for patients with malignant and 3/5 dimensions (mobility, self-care, usual activities) for patients with benign disease 3 months after surgery (p < 0.05). Patients with malignant disease reported an increase in depressive symptoms, patients with benign disease had a decrease in anxiety symptoms (HADS-D; depression: 5.00 vs 6.51, p = 0.002; anxiety: 8.04 vs. 6.34, p = 0.030). Regarding pancreatic-disease-specific symptoms (EORTC-QLQ-PAN26), patients with malignant disease reported increased problems with taste, weight loss, weakness in arms and legs, dry mouth, body image and troubling side effects at three months. Patients with benign disease indicated more weakness in arms and legs, troubling side effects but less future worries at three months. CONCLUSION: Patient-reported outcomes of patients undergoing pancreatic surgery for benign vs. malignant disease show important differences. Patients with malignant tumors report more severely decreased quality of life 3 months postoperatively than patients with benign tumors.

BACKGROUND: Postoperative pancreatic fistula (POPF) as well as postoperative biliary fistula (POBF) are considered the main source of postoperative morbidity and mortality after pancreatoduodenectomy (PD). However, little is known about the incidence and complications of combined POPF/POBF compared to isolated POPF or POBF. METHODS: This single-center study investigated retrospectively the incidence and postoperative outcome of combined POPF/POBF compared to isolated fistulas following PD in a tertiary German pancreatic center between 2009 and 2018. RESULTS: A total of 678 patients underwent PD for benign and malignant periampullary lesions. Combined fistulas occurred in 6%, isolated POPF in 16%, and isolated POBF in 2%. Pancreatic ductal adenocarcinoma and chronic pancreatitis had a protective effect on the occurrence of combined fistulas, whereas serous cystadenoma and pancreatic metastasis were risk factors. Morbidity (Grade C fistula, post-pancreatectomy hemorrhage, revisional surgery) and mortality was significantly higher in patients with combined fistulas than in those with isolated fistula. Moreover, the duration of ICU stay was longer. CONCLUSIONS: A combined POPF/POBF is associated with a significant increase of morbidity and mortality compared to isolated fistulas after PD. Early surgical revision in these patients may improve the postoperative survival rate.

Due to its rising incidence, pancreatic neoplasia, which mainly include adenocarcinomas, neuroendocrine and cystic neoplasia of the pancreas, is becoming increasingly relevant in everyday clinical practice.Based on a systematic literature search, a working group of pancreatic experts developed evidence-based recommendations for surgical indications in pancreatic neoplasia to improve the quality.There is a clear surgical indication for primary or secondary resectable pancreatic carcinomas without metastasis, for functionally active, symptomatic and functionally inactive neuroendocrine neoplasia of more than 2 cm in size and for cystic neoplasm with symptoms or signs of malignancy including all intraductal papillary-mucinous neoplasia (IPMN) of the main duct and mixed type, all mucinous-cystic neoplasia (MCN) > 4 cm and all solid pseudopapillary neoplasia (SPN). Surgery can be indicated for pancreatic carcinomas with isolated arterial vascular infiltration or for long periods of stable oligometastasis, regarding neuroendocrine neoplasias for metastasis or debulking surgery as well as for branch-duct IPMN with risk criteria and MCN <4 cm. There is no primary indication for surgery in locally advanced and metastatic pancreatic cancer or asymptomatic serous-cystic neoplasia (SCN).The indication for surgery should always be individualized taking into account age, comorbidities and patient wishes.

BACKGROUND: Current guidelines discourage surgery for serous cystic neoplasms (SCN) of the pancreas, because of their benign character, slow growth, and excellent prognosis. Nevertheless, SCN continue to contribute up to 30% of resected cystic pancreatic lesions worldwide. METHODS: Spectrum of indications and outcomes of surgery were analysed in a retrospective series of 133 SCN at a single high-volume center in Germany between 2004 and 2019. RESULTS: Relevant symptoms justified surgery in 60% of patients with SCN, while 40% underwent surgery because of preoperative diagnostic uncertainty about suspected malignancy. There were 4 malignant SCN (3%). Ninety-day mortality was 0.75%, major morbidity - 15%, 10-year survival - 95%. Risks of malignant transformation and of postoperative mortality were similarly low. CONCLUSIONS: Surgery is reasonable and safe for symptomatic patients with SCN. Preoperative diagnostic uncertainty is the main reason for futile resections of benign asymptomatic SCN. Conservative management with close initial surveillance should be the first choice for this population. Surgery for supposed SCN without symptoms is justified only in carefully selected patients with suspected malignancy.

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) has the worst prognosis of all malignant tumors due to unavailable screening methods, late diagnosis with a low proportion of resectable tumors and resistance to systemic treatment. Complete tumor resection remains the cornerstone of modern multimodal strategies aiming at long-term survival. This study was performed to investigate the overall rate of long-term survival (LTS) and its contributing factors. METHODS: This was a retrospective single-center analysis of consecutive patients undergoing pancreaticoduodenectomy (PD) for PDAC between 2007 and 2014 at the St. Josef Hospital, Ruhr University Bochum, Germany. Clinical and laboratory parameters were assessed and evaluated for prediction of LTS with Cox regression analysis. RESULTS: The overall rate of LTS after PD for PDAC was 20.4% (34/167). Median survival was 24 months regardless of adjuvant treatment. Carbohydrate antigen 19-9 levels, tumor grade, lymph vessel invasion, perineural invasion and reduced general condition were significantly associated with LTS in univariate analysis (P < 0.05). Serum levels of carbohydrate antigen 19-9, American Joint Committee on Cancer stage, tumor grade, abdominal pain, male, exocrine pancreatic insufficiency and duration of postoperative hospital stay were independent predictors of cancer survival in multivariable analysis. CONCLUSIONS: Cancer related characteristics are associated with LTS in multimodally treated patients after curative PDAC surgery.

BACKGROUND: Studies demonstrated that operating room personnel are exposed to anesthetic gases such as sevoflurane (SEVO). Measuring the gas burden is essential to assess the exposure objectively. Air pollution measurements and the biological monitoring of urinary SEVO and its metabolite hexafluoroisopropanol (HFIP) are possible approaches. Calculating the mass of inhaled SEVO is an alternative, but its predictive power has not been evaluated. We investigated the SEVO burdens of abdominal surgeons and hypothesized that inhaled mass calculations would be better suited than pollution measurements in their breathing zones (25 cm around nose and mouth) to estimate urinary SEVO and HFIP concentrations. The effects of potentially influencing factors were considered. METHODS: SEVO pollution was continuously measured by photoacoustic gas monitoring. Urinary SEVO and HFIP samples, which were collected before and after surgery, were analyzed by a blinded environmental toxicologist using the headspace gas chromatography-mass spectrometry method. The mass of inhaled SEVO was calculated according to the formula mVA = cVA·(Equation is included in full-text article.)·t·ρ VA aer. (mVA: inhaled mass; cVA: volume concentration; (Equation is included in full-text article.): respiratory minute volume; t: exposure time; and ρ VA aer.: gaseous density of SEVO). A linear multilevel mixed model was used for data analysis and comparisons of the different approaches. RESULTS: Eight surgeons performed 22 pancreatic resections. Mean (standard deviation [SD]) SEVO pollution was 0.32 ppm (0.09 ppm). Urinary SEVO concentrations were below the detection limit in all samples, whereas HFIP was detectable in 82% of the preoperative samples in a mean (SD) concentration of 8.53 µg·L (15.53 µg·L; median: 2.11 µg·L, interquartile range [IQR]: 4.58 µg·L) and in all postoperative samples (25.42 µg·L [21.39 µg·L]). The mean (SD) inhaled SEVO mass was 5.67 mg (2.55 mg). The postoperative HFIP concentrations correlated linearly to the SEVO concentrations in the surgeons' breathing zones (ß = 216.89; P < .001) and to the calculated masses of inhaled SEVO (ß = 4.17; P = .018). The surgeon's body mass index (BMI), age, and the frequency of surgeries within the last 24 hours before study entry did not influence the relation between HFIP concentration and air pollution or inhaled mass, respectively. CONCLUSIONS: The biological SEVO burden, expressed as urinary HFIP concentration, can be estimated by monitoring SEVO pollution in the personnel's individual breathing zone. Urinary SEVO was not an appropriate biomarker in this setting.

Neuroendocrine neoplasms of the pancreas (pNEN) have an increasing incidence and prevalence. Thus, this entity is of increasing clinical significance. Patients with pNEN become clinically apparent due to different and unspecific symptoms. Some tumours secrete hormones and peptides and become clinically symptomatic. In general, these tumours can metastasise early and even small tumours lead to distant metastases. Nonetheless, primary tumour size and grading are important prognostic factors. On the basis of a systematic literature research and the formulation of key issues according to the PICO system, therapeutic concepts were established. These concepts were evaluated with a Delphi process among the members of the pancreas research group and the indications for surgery group of the German Society of General and Visceral Surgery. Thus this article gives an overview of the surgical treatment modalities and indications for the treatment of pNEN. Surgery is still the gold standard in treatment and the only potential chance of cure. Surgery is indicated for sporadic as well as hereditary pNEN > 2 cm independent of the functional activity. A so called "wait and see" strategy might be indicated in smaller pNEN; however, there is little evidence for this approach. In this respect, pNEN of 1â-â2 cm represent a surgical indication. The treatment of hereditary pNEN is challenging and should be interdisciplinary. Even in the case of distant metastases, a curative approach might be feasible and multimodal treatment is indicated.

Chronic pancreatitis is a recurrent disease with repeating exacerbations of inflammation of the pancreatic gland - associated with belt-like back pain. Without treatment, recurrent chronic pancreatitis leads to development of opioid-dependent pain. The chronic pancreatitis leads to recurrent hospital stays for the affected patient and socioeconomic challenges. In progress it can lead to local complications of chronic pancreatitis, such as formation of pseudocysts, biliary duct obstruction, duodenal obstruction or portal hypertension. The aim of this article is a detailed description of the indication for surgical therapy in chronic pancreatitis. The underlying analysis was a systematic literature research and evaluation, the formulation of key questions according to the PICO system and the evaluation of indications and key statements and questions, as implemented in a three level Delphi process among the members of the pancreas research group and the indications for the surgery group of the German Society of General and Visceral Surgery (DGAV). Surgical resection of the inflammatory pancreatic head pseudotumour, after initial conservative therapy, is a highly efficient therapy for the control of pain and the avoidance of complications in chronic pancreatitis. For this purpose, well evaluated surgical strategies are available. Delay in surgical therapy can lead to chronic pain, kachexia and malnutrition and increase complications of surgical therapy.

BACKGROUND: Surgery for pancreatic cancer in Germany is increasing due to the climbing incidence of this cancer in the population. This review presents a summary of modern evidence-based indications for surgery in patients with pancreatic ductal adenocarcinoma (PDAC). METHODS: The German Society for General and Visceral Surgery (DGAV) authorised a task force to define evidence based indications for surgery in patients with PDAC. A systematic literature search in Medline and Cochrane Library databases (1989â-â2019) was performed. Recommendations were summarised on the basis of the most relevant and recent guidelines and clinical studies and then voted by members of the Working Group on Hepato-Biliary and Pancreatic Diseases (CALGP) in a Delphi procedure. RESULTS: Indications for surgery in patients with PDAC should be set by experienced pancreatic surgeons within a tumour board. Decisions should consider the guidelines as well as the individual patient characteristics. Large vessel infiltration, metastatic disease and severe comorbidities are the most common contraindications for surgery. Borderline-resectable, primary resectable oligometastatic and secondary resectable PDAC should be preferably managed at high-volume centres as a part of clinical studies. Centralisation of pancreatic surgery reduces mortality and improves survival. Palliative bypass surgery as well as staging laparoscopy are still indicated in a large proportion of patients with PDAC. CONCLUSION: Irrespective of the recent development of multimodal therapeutic concepts, surgical resection remains the sole chance of long-term cure for patients with PDAC. Due to the significant proportion of patients in advanced stages of the disease, palliative surgery still plays an important role in the complex management of this cancer.

A steady improvement in modern imaging as well as increasing age in society have led to an increasing number of cystic pancreatic tumours being detected. Pancreatic cysts are a clinically challenging entity because they span a broad biological spectrum and their differentiation is often difficult, especially in small tumours. Therefore, they require a differentiated indication for indication of surgery. To determine recommendations for the surgical indication in cystic tumours of the pancreas, a quality committee for pancreatic diseases of the German Society for General and Visceral Surgery performed a systematic literature search and created this review. Based on the current evidence, signs of malignancy and high-risk criteria (icterus due to cystic pancreatic duct obstruction in the bile duct, enhancing mural nodules ≥ 5 mm or solid components in the cyst or pancreatic duct ≥ 10 mm), as well as symptoms, are a surgical indication, independently of the cyst entity (except pseudocysts). If the entity of the pancreatic cyst is detectable by diagnostic imaging, all main duct IPMN and IPMN of the mixed type, all MCN > 4 cm and all SPN should be resected. SCN and branch-duct IPMN without worrisome features do not constitute an indication for surgery. The indication of operation in branch-duct IPMN with relative risk criteria and MCN < 4 cm is the subject of current discussions and should be individualised. By defining indication recommendations, the present work aims to improve the indication quality in cystic pancreatic tumours. However, the surgical indication should always be individualised, taking into account age, comorbidities and the patient's wishes.

BACKGROUND: 15 to 20% of patients with acute pancreatitis develop necrosis of the pancreatic parenchyma or extrapancreatic tissue. The disease is associated with a mortality rate of up to 20%. The mainstays of treatment consist of intensive medical care and surgical and interventional therapy. METHODS: A systematic literature search focused on indications for surgical and interventional therapy of necrotising pancreatitis. 85 articles were analysed for this review. By using the Delphi method, the results were presented to the quality committee for pancreas diseases of the German Society for General and Visceral Surgery and to expert pancreatologists in an interactive conference using plenary voting during the visceral medicine congress 2019 in Wiesbaden. For the finalised recommendations, an agreement of 84% of participants was achieved. RESULTS: Documented or clinical suspicion of infected, necrotising pancreatitis are indications for surgical and interventional therapy (recommendation grade: strong; evidence grade; low). Sterile necrosis is a less common indication for intervention due to late complications or persistent severe pancreatitis. Invasive interventions should be delayed when possible until four weeks after onset of pancreatitis. Optimal treatment strategy consists of a "step-up approach" (evidence grade: high; recommendation grade: strong). The first step is catheter drainage, followed, if necessary, by minimally invasive surgical or interventional necrosectomy. If minimally invasive techniques do not result in clinical improvement, open necrosectomy is necessary. 35 to 50% of patients are successfully treated with drainage alone. Indications for emergency intervention are bowel perforation, bowel ischemia and bleeding. Surgical decompression of abdominal compartment syndrome is indicated if the patient is refractory to medical treatment and percutaneous drainage. Abscesses and symptomatic pseudocysts are indications for interventional drainage. Early cholecystectomy during index admission is recommended for patients with mild biliary pancreatitis. Cholecystectomy should be delayed after severe, biliary pancreatitis. CONCLUSION: The recommendations for surgical an interventional therapy of necrotising pancreatitis address the basis of current indications in literature. They should serve in daily practice as a reference standard for decision making in multidisciplinary teams.

BACKGROUND: Postoperative pancreatic fistula (POPF) is a major factor for morbidity and mortality after pancreatic resection. Risk stratification for POPF is important for adjustment of treatment, selection of target groups in trials and quality assessment in pancreatic surgery. In this study, we built a risk-prediction model for POPF based on a large number of predictor variables from the German pancreatic surgery registry StuDoQ|Pancreas. METHODS: StuDoQ|Pancreas was searched for patients, who underwent pancreatoduodenectomy from 2014 to 2016. A multivariable logistic regression model with elastic net regularization was built including 66 preoperative und intraoperative parameters. Cross-validation was used to select the optimal model. The model was assessed via area under the ROC curve (AUC) and calibration slope and intercept. RESULTS: A total of Nâ¯=â¯2488 patients were included. In the optimal model the predictors selected were texture of the pancreatic parenchyma (soft versus hard), body mass index, histological diagnosis pancreatic ductal adenocarcinoma and operation time. The AUC was 0.70 (95% CI 0.69-0.70), the calibration slope 1.67 and intercept 1.12. In the validation set the AUC was 0.65 (95% CI 0.64-0.66), calibration slope and intercept were 1.22 and 0.42, respectively. CONCLUSION: The model we present is a valid measurement instrument for POPF risk based on four predictor variables. It can be applied in clinical practice as well as for risk-adjustment in research studies and quality assurance in surgery.

BACKGROUND/OBJECTIVE: The impact of preoperative biliary stenting (PBS) before pancreatoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) is controversial. METHODS: Patients undergoing PD with or without PBS for PDAC were identified from the German DGAV-StuDoQlPancreas registry. The impact of PBS on perioperative complications was analyzed. RESULTS: 1133 patients undergoing PD for PDAC were identified from the registry. After matching, 480 PBS patients vs. 480 patients without PBS were analyzed. Postoperative complications Clavien-Dindo classification (CDC) grade IIIa-IVb were higher in PBS patients (PBS 27% vs. no PBS 22%, pâ¯=â¯0.027). 320 PBS patients (66%) had no history of jaundice. In these patients, PBS was associated with higher morbidity. In contrast, PBS was not associated with higher complication rates in patients with history of jaundice. Serum bilirubin levels of 15â¯mg/dl and higher lead to more CDC IIIa-IVb (24% vs. 28%, pâ¯=â¯0.053) and higher mortality (3% vs. 7%, pâ¯<â¯0.001). PBS in patients with serum bilirubin levels of >15â¯mg/dl increased CDC IIa-IVb complications (21% vs. 50%, pâ¯=â¯0.001), mortality was equivalent. CONCLUSION: Most PBS procedures were performed in patients with no history of jaundice and increased morbidity. Serum bilirubin levels >15â¯mg/dl lead to higher morbidity and mortality. PBS correlated with higher complication rates in these patients.

BACKGROUND AND OBJECTIVE: This is the first study to compare the safety and efficacy of vacuum-assisted biopsy (VAB) using a self-contained hand-held system compared to those of ultrasound-guided and computed tomography-guided core needle biopsy (US-CNB and CT-CNB) and to incisional biopsy (IB). METHODS: VAB was performed in an outpatient setting under local anesthesia. Safety, diagnostic accuracy, time, and cost expenditures of biopsy were compared between VAB, US-CNB, CT-CNB, and IB in 211 consecutive patients. RESULTS: VAB was applied in 78 patients, US-CNB in 51, CT-CNB in 45, and IB in 37. Patient characteristics did not differ between groups. Sample volume of VAB was 392.5 mm3 , 4062 mm 3 for IB, and 25.1 to 34.5 mm 3 for CNB, P < .001. VAB discriminated between malignant and benign lesions with the highest accuracy of 96% and determined sarcoma grading accurately in 95%. VAB and CNB had no complications vs 5% for IB. Duration of VAB was 5 ± 2 minutes, equal to US-CNB and shorter than CT-CNB and IB. Expenditures for VAB were higher than for US-CNB and lower than CT-CNB and IB. CONCLUSION: VAB is an accurate, safe, cost-effective, and time-saving outpatient diagnostic procedure for patients with soft-tissue tumors and presents a viable alternative to IB.

Continuously rising incidence and prevalence, frequent hospitalisation, development of opioid dependence, and early retirement of young people demonstrate the enormous socioeconomic impact of chronic pancreatitis. The aims of therapy include pain relief, improved quality of life, management of complications, cancer prevention and preservation of function. Since medical and endoscopic approaches of conservative therapy have proved to be ineffective in the long term, surgery remains the mainstay of treatment and should be considered as early as possible. Surgery encompasses a wide spectrum of methods, ranging from simple drainage procedures and conventional resections to various hybrid techniques. The choice of optimal surgical management should consider the unique pathomorphologic changes of each patient and be performed at a high-volume pancreas centre. This review presents the current evidence-based state of knowledge about chronic pancreatitis from a surgical point of view with a practical summary of therapeutic strategies according to the available guidelines and considering the most recent literature.

BACKGROUND: Double-loop (DL) reconstruction after pancreaticoduodenectomy (PD), diverting pancreatic from biliary secretions, has been reported to reduce rates and severity of postoperative pancreatic fistula (POPF) compared to single loop (SL) reconstruction at the price of prolonged operative duration. This study investigated the feasibility of a new reconstruction method combining the advantages of DL with the simplicity of SL in patients with high-risk pancreas. METHODS: A modified single-loop (mSL) reconstruction was used in patients undergoing PD with a soft pancreatic remnant and a pancreatic duct smaller than 3 mm (n = 50). The loop between the pancreatic and the biliary anastomoses was left longer and a side-to-side jejunojejunal anastomosis was performed between them at the lowest point to promote isolated flow of pancreatic and biliary secretions. Rate and severity of POPF, mortality, duration of surgery, and POPF-associated morbidity were compared to those of 50 matched patients with SL and 25 patients with DL reconstruction. RESULTS: Duration of surgery was 57 min longer for DL, but equal for mSL and SL. The POPF rate did not differ between the three groups. The severity of POPF was more pronounced in the SL group (62% grade C: p = 0.011). Mortality and major morbidity were lower and hospital stay shorter in the mSL and DL groups compared to the SL group. CONCLUSIONS: The new mSL reconstruction was safer than conventional SL and faster to perform than DL reconstruction in patients with a high-risk pancreas. It did not influence the rate of POPF, but reduced its severity, leading to less major morbidity and mortality.

BACKGROUND: This study aimed to evaluate the effect of a new combined method of covering the pancreatic anastomosis or stump with a cyanoacrylate and a falciform patch (CAFP) on the occurrence of postoperative pancreatic fistula (POPF). METHODS: Patients undergoing a pancreaticoduodenectomy (PD) or a distal pancreatectomy (DP) were recruited over a period of 12 months. The pancreaticojejunostomy in PD and the stump in DP were sealed with cyanoacrylate glue and wrapped in a falciform patch. Incidence and severity of POPF and associated postoperative complications were retrospectively compared with historical controls of 750 PD and 336 DP at the same institution and with current data from the literature. RESULTS: The new method was applied in 27 PD and 25 DP. The rate of clinically relevant POPF after PD with CAFP was 22.2% compared to 14.4% in historical patients, p = 0.26. The rate of clinically relevant POPF after DP with CAFP was 36% compared to 30% in historical patients, p = 0.65. CONCLUSION: Sealing the pancreatic anastomosis or stump with a combination of a cyanoacrylate glue and a falciform patch didn't reduce the rate of POPF after major pancreatic resections.

A 5-year-old boy sustained blunt abdominal trauma in a car crash. The buckle mechanism of the five-point harness of his child safety seat compressed his upper abdomen causing an isolated complete pancreatic rupture. Diagnosis was delayed due to subtle symptoms and normal initial findings. A CT scan confirmed diagnosis. An emergency limited central pancreatic resection was performed. The outcome was excellent.

INTRODUCTION: Determining the dignity of intraductal papillary mucinous neoplasms (IPMNs) by imaging procedures is challenging. Various CT-based criteria were evaluated. PATIENTS AND METHODS: Preoperative CT scans from 47 patients with IPMN were analyzed. Predefined criteria of malignancy were compared between patients with benign (bIPMN; n = 28) and malignant (mIPMN; n = 19) tumors, and a summation score was determined. RESULTS: Preoperative carbohydrate-antigen 19-9 levels were higher in patients with mIPMN (p = 0.013). The diameter of the main pancreatic duct was greater in patients with mIPMN (p < 0.0001). More patients with mIPMN showed bile duct obstruction (p = 0.0076), solid tumor components (p = 0.0076), contrast enhancement in cystic walls (p = 0.0086), peripancreatic lymph nodes (p = 0.0076), and abrupt diameter changes of the main pancreatic duct (p = 0.0008). The CT density of the cysts was higher in mIPMN (p = 0.0063). The diagnostic accuracy of the summation score (sensitivity: 0.84, specificity: 0.96) was greater when compared to each individual CT parameter. CONCLUSIONS: The prevalence and extent of various CT-based abnormalities are greater in patients with mIPMN, but the wide overlap limits the diagnostic value of each individual parameter. A simple summation score largely enhances the diagnostic accuracy.

BACKGROUND: Although laparoscopic cholecystectomy is recommended as standard treatment for acute cholecystitis, in 10-30 % a conversion to open cholecystectomy is required. Among some surgeons, this is still perceived as a "complication." The aim of our study was to define characteristics and outcome of patients with acute cholecystitis undergoing conversion cholecystectomy. METHODS: Over a 9-year period, 464 consecutive patients undergoing cholecystectomy for acute cholecystitis were analyzed for demographic, preoperative, intraoperative, histopathological, and laboratory findings and surgical outcome parameters. RESULTS: Patients with conversion cholecystectomy were characterized by younger age, lower American Society of Anesthesiologists (ASA) score, and less cardiac comorbidities compared to patients with primary open cholecystectomy. Severity of inflammation on the clinical and histopathological level was similar and comparable. Overall complication rate, mortality, and median hospital stay were significantly lower compared to those of primary open cholecystectomy group. CONCLUSIONS: There are no disadvantages for patients undergoing conversion cholecystectomy compared to primary open cholecystectomy. The outcome is influenced by general condition and comorbidities rather than by the surgical approach. Underlying fear of conversion should not avoid a laparoscopic approach in patients with acute cholecystitis.
