RESUMO
BACKGROUND: Longlasting and unbearable pain is the most common and striking symptom of chronic pancreatitis. Accordingly, pain relief and improvement in patients' quality of life are the primary goals in the treatment of this disease. This systematic review aims to summarize the available data on treatment options. METHODS: A systematic search of MEDLINE/PubMed and the Cochrane Library was performed according to the PRISMA statement for reporting systematic reviews and meta-analysis. The search was limited to randomized controlled trials and meta-analyses. Reference lists were then hand-searched for additional relevant titles. The results obtained were examined individually by two independent investigators for further selection and data extraction. RESULTS: A total of 416 abstracts were reviewed, of which 367 were excluded because they were obviously irrelevant or represented overlapping studies. Consequently, 49 full-text articles were systematically reviewed. CONCLUSIONS: First-line medical options include the provision of pain medication, adjunctive agents and pancreatic enzymes, and abstinence from alcohol and tobacco. If medical treatment fails, endoscopic treatment offers pain relief in the majority of patients in the short term. However, current data suggest that surgical treatment seems to be superior to endoscopic intervention because it is significantly more effective and, especially, lasts longer.

BACKGROUND: The effect of bacterobilia on morbidity after pancreatoduodenectomy remains unclear. The aim of this study was to examine the influence of positive intraoperative bile cultures and perioperative antibiotic prophylaxis on morbidity measured using the Comprehensive Complication Index, a weighted composite of postoperative complications. METHODS: Intraoperative bile cultures of 182 patients who underwent pancreatoduodenectomy were obtained. We examined the effect of intraoperative bile cultures and perioperative antibiotic prophylaxis on the Comprehensive Complication Index and the occurrence of postoperative complications. To this aim, we performed general linear models controlling for relevant demographic and perioperative factors. RESULTS: Positive (versus negative) intraoperative bile cultures were associated with a higher mean Comprehensive Complication Index (25.34 vs 16.81, P = .025). The mean Comprehensive Complication Index differed significantly between individuals with positive intraoperative bile cultures and bacterial strains not covered by perioperative antibiotic prophylaxis (26.2) versus positive intraoperative bile cultures and bacterial strains sensitive to perioperative antibiotic prophylaxis (22.7) (P = .045). Positive (versus negative) intraoperative bile cultures were associated with 4.75 times (95% confidence interval: 1.74-13.00, P = .002) greater odds of wound infections. The odds of wound infection were 1.93 times (95% confidence interval: .47-8.04) greater in those with positive intraoperative bile cultures and adequate perioperative antibiotic prophylaxis and 6.14 times (95% confidence interval: 2.17-17.35) greater in those with positive intraoperative bile cultures and inadequate perioperative antibiotic prophylaxis (versus negative intraoperative bile cultures) (P = .001). CONCLUSION: Bacterobilia is associated with a significant increase in Comprehensive Complication Index and wound infections after pancreatoduodenectomy, which may be reduced by administration of a specific perioperative antibiotic prophylaxis. Acquisition of bile cultures sampled through the external conduit of patients with preoperative biliary drainage could help in selecting a specific perioperative antibiotic prophylaxis and patients with bile duct stents might benefit from broad spectrum perioperative antibiotic prophylaxis.

BACKGROUND: Chylous leakage is a relevant clinical problem after major abdominal surgery leading to an increased length of stay. DATA SOURCES: A systematic search of MEDLINE/PubMed and the Cochrane Library was performed according to the PRISMA statement. The search for the MeSH terms "chylous ascites" and/or "lymphatic fistula" retrieved a total of 2,348 articles, of which 36 full-text articles were reviewed by 2 independent investigators. RESULTS: Chylous ascites is described with an incidence of up to 11%, especially after pancreatic surgery. The incidence is increasing with the number of lymph nodes harvested. In patients treated with total parenteral nutrition, conservative treatment is demonstrated to be effective in up to 100% of cases. CONCLUSIONS: The extent of abdominal surgery mainly predicts the risk of chylous ascites. Conservative treatment has been shown to be effective in almost all cases and is the treatment of choice.

Pancreatic neuroendocrine neoplasms (PNENs) are rare and account for only 2%-4% of all pancreatic neoplasms. All PNENs are potential (neurendocrine tumors PNETs) or overt (neuroendocrine carcinomas PNECs) malignant, but a subset of PNETs is low-risk. Even in case of low-risk PNETs surgical resection is frequently required to treat hormone-related symptoms and to obtain an appropriate pathological diagnosis. Low-risk PNETs in the body and the tail are ideal for minimally-invasive approaches which should be tailored to the individual patient. Generally, surgeons must aim for parenchyma sparing in these cases. In high-risk and malignant PNENs, indications for tumor resection are much wider than for pancreatic adenocarcinoma, in many cases due to the relatively benign tumor biology. Thus, patients with locally advanced and metastatic PNETs may benefit from extensive resection. In experienced hands, even multi-organ resections are accomplished with acceptable perioperative morbidity and mortality rates and are associated with excellent long term survival. However, poorly differentiated neoplasms with high proliferation rates are associated with a dismal prognosis and may frequently only be treated with chemotherapy. The evidence on surgical treatment of PNENs stems from reviews of mostly single-center series and some analyses of nation-wide tumor registries. No randomized trial has been performed to compare surgical and non-surgical therapies in potentially resectable PNEN. Though such a trial would principally be desirable, ethical considerations and the heterogeneity of PNENs preclude realization of such a study. In the current review, we summarize recent advances in the surgical treatment of PNENs.
