Backgrounds/Aims: Mirizzi syndrome (MS) is an uncommon complication of cholelithiasis. The aim of this study is to evaluate our 15-year experience in this challenging entity and to propose a new classification for this disease. Methods: A retrospective study including patients diagnosed with Mirizzi syndrome and undergoing surgical procedures for Mirizzi syndrome between January 2000 and October 2015 was conducted. Data collected included clinical, surgical procedure, postoperative morbidity. Patients were evaluated according to the Csendes classification and the proposed system, in which patients were divided into three types and three subtypes. Results: 28 patients were included for analysis. They accounted as the 0.5% of a total of 4853 cholecystectomies performed in the study period. There were 21 women and 7 men. Initial laparotomic approach was performed in 12 patients and in 16 patients laparoscopic procedures were attempted. The procedure was completed in only 6 patients, 5 presenting type I and 1 type II Mirizzi syndrome. Mean postoperative stay was 15±9 days. Postoperative morbidity rate was 28%. Postoperative mortality was none. Conclusions: Laparoscopic surgery for Mirizzi syndrome has been shown succesful only in early stages. A novel classification is proposed, based on the types of common bile duct injuries and in the presence cholecystoenteric fistula. (Ann Hepatobiliary Pancreat Surg 2017;21:67-75)

Age-adjusted charlson comorbidity index (a-cci) score has been used to weight comorbid conditions in predicting adverse outcomes. A retrospective cohort study on adult patients diagnosed with complicated intra-abdominal infections (ciAi) requiring emergency surgery was conducted in order to elucidate the role of age and comorbidity in this scenario. two main outcomes were evaluated: 90-day severe postoperative complications (grade ≥ 3 of Dindo-Clavien Classification), and 90-day all-cause mortality. 358 patients were analyzed. a-CCI score for each patient was calculated and then divided in two comorbid categories whether they were ≤ or > to percentile 75 (= 4): Grade-A (0-4) and Grade-B (≥ 5). Univariate and multivariate regression analyses were performed, and the predictive validity of the models was evaluated by the area under the receiver operating characteristics (AUROC) curve. Independent predictors of 90-day severe postoperative complications were Charlson Grade-B (Odds Ratio [OR] = 3.49, 95% confidence interval [95%CI]: 1.86-6.52; p < 0.0001), healthcarerelated infections (oR = 7.84, 95%CI: 3.99-15.39; p < 0.0001), diffuse peritonitis (OR = 2.64, 95%CI: 1.45-4.80; p < 0.01), and delay of surgery > 24 hours (OR = 2.28, 95%CI: 1.18-4.68; p < 0.02). The AUROC was 0.815 (95%CI: 0.758-0.872). Independent predictors of 90-day mortality were Charlson Grade-B (OR = 8.30, 95%CI: 3.58-19.21; p < 0.0001), healthcare-related infections (OR = 6.38, 95%CI: 2.72-14.95; p < 0.0001), sepsis status (OR = 3.98, 95%CI: 1.04-15.21; p < 0.04) and diffuse peritonitis (oR = 3.06, 95%CI: 1.29-7.27; p < 0.01). The AUROC for mortality was 0.887 (95%CI: 0.83-0.93). Posthoc sensitivity analyses confirmed that the degree of comorbidity, estimated by using an age-adjusted score, has a critical impact on the postoperative course following emergency surgery for ciAi. early assessment and management of patient's comorbidity is mandatory at emergency setting. Complicated intra-abdominal infections (cIAI) are the second most common site of invasive infections in critically ill patients 1. They are associated with poor outcomes in high risk patients, with an estimated overall mortality ranging from 10% to 35% 2-4. cIAI implies the extension of the process beyond the organ to the peritoneal cavity and is then associated with localized or diffuse peritonitis. A landmark multi-centric international prospective cohort study, evaluated adult patients presenting with cIAI undergoing surgery or interventional drainage and identified the independent risk factors of mortality 3. They were namely patient's age, immunosuppression, small bowel perforations, a delay of initial intervention over 24 hours, and intensive care unit (ICU) admission. Previous studies on IAI also showed other factors that potentially influence patient's prognosis, such as an extended peritonitis, sepsis development, or healthcare-related infections 4. An emergency surgical procedure is often needed in the management of cIAI, leading to a non-despicable cost burden to healthcare ...

BACKGROUND:Polycystic liver disease (PLD) has a low frequency overall in the worldwide population. As the patient's symptoms are produced by the expansion of hepatic volume, the different therapeutic alternatives are focused on reducing it. Surgery is still considered the most effective treatment for symptomatic PLD. The aim of this study was to evaluate the long-term outcomes of laparoscopic surgery for PLD.MATERIALS AND METHODS:This study included 14 patients who were diagnosed with symptomatic PLD and underwent surgery by a laparoscopic approach between 2004 and 2012. It involved collecting data on the characteristics of those patients and their liver disease, surgical procedures, intra- and postoperative complications, and the long-term follow-up.RESULTS:Twelve laparoscopic multiple-cyst fenestrations and two segmentary liver resections associated with remaining-cyst fenestration were performed. One procedure required conversion to laparotomy and the other was complicated by anhepatic severe bleeding. The rest of the procedures were uneventful. One patient developed persistent self-limited ascites in the immediate postoperative period. Symptoms disappeared after surgical intervention in all patients. During a median follow-up of 62 months (range 14-113 months), there were two clinical recurrences and one asymptomatic radiological recurrence. One patient required further surgery.CONCLUSION:Laparoscopic cystic fenestration and laparoscopic liver resection are safe and long-term, effective procedures for the treatment of symptomatic PLD. Severity and morphological characteristics of the hepatic disease will determine the surgical indication and the optimal approach for each patient.
