BACKGROUND: Postoperative upper gastrointestinal fistula (PUGIF) is a devastating complication, leading to high mortality (reaching up to 80%), increased length of hospital stay, reduced health-related quality of life and increased health costs. Nutritional support is a key component of therapy in such cases, which is related to the high prevalence of malnutrition. In the prophylactic setting, enteral nutrition (EN) is associated with a shorter hospital stay, a lower incidence of severe infectious complications, lower severity of complications and decreased cost compared to total parenteral nutrition (TPN) following major upper gastrointestinal (GI) surgery. There is little evidence available for the curative setting after fistula occurrence. We hypothesize that EN increases the 30-day fistula closure rate in PUGIF, allowing better health-related quality of life without increasing the morbidity or mortality. METHODS/DESIGN: The NUTRILEAK trial is a multicenter, randomized, parallel-group, open-label phase III trial to assess the efficacy of EN (the experimental group) compared with TPN (the control group) in patients with PUGIF. The primary objective of the study is to compare EN versus TPN in the treatment of PUGIF (after esophagogastric resection including bariatric surgery, duodenojejunal resection or pancreatic resection with digestive tract violation) in terms of the 30-day fistula closure rate. Secondary objectives are to evaluate the 6-month postrandomization fistula closure rate, time of first fistula closure (in days), the medical- and surgical treatment-related complication rate at 6 months after randomization, the fistula-related complication rate at 6 months after randomization, the type and severity of early (30 days after randomization) and late fistula-related complications (over 30 days after randomization), 30-day and 6-month postrandomization mortality rate, nutritional status at day 30, day 60, day 90 and day 180 postrandomization, the mean length of hospital stay, the patient's health-related quality of life (by self-assessment questionnaire), oral feeding time and direct costs of treatment. A total of 321 patients will be enrolled. DISCUSSION: The two nutritional supports are already used in daily practice, but most surgeons are reluctant to use the enteral route in case of PUGIF. This study will be the first randomized trial testing the role of EN versus TPN in PUGIF. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03742752.

Laparoscopic versus open liver resection for intrahepatic cholangiocarcinoma. Report of an international multicenter cohort study with propensity score matching

Background: Intrahepatic cholangiocarcinoma is a rare disease with a poor prognosis. In patients where surgical resection is possible, outcome is influenced by perioperative morbidity and lymph node status. Laparoscopic liver resection is associated with improved clinical and oncological outcomes in primary and metastatic liver cancer compared with open liver resection, but evidence on intrahepatic cholangiocarcinoma is still insufficient.The primary aim of this study was to compare overall survival for a large series of patients treated for intrahepatic cholangiocarcinoma by open or laparoscopic approach. Secondary objectives were to compare disease-free survival, predictors of death, and recurrence.Methods: Patients treated with laparoscopic or open liver resection for intrahepatic cholangiocarcinoma from 2000 to 2018 from 3 large international databases were analyzed retrospectively. Each patient in the laparoscopic resection group (case) was matched with 1 open resection control (1:1 ratio), through a propensity score calculated on clinically relevant preoperative covariates. Overall and disease-free survival were compared between the matched groups. Predictors of mortality and recurrence were analyzed with Cox regression, and the Textbook Outcomes were described.Results: During the study period, 855 patients met the inclusion criteria (open liver resection = 709, 82.9%; laparoscopic liver resection = 146, 17.1%). Two groups of 89 patients each were analyzed after propensity score matching, with no significant difference regarding pre-and postoperative variables. Overall survival at 1, 3, and 5 years was 92%, 75%, and 63% in the laparoscopic liver resection group versus 92%, 58%, and 49% in the open liver resection group (P = .0043). Adjusted Cox regression revealed severe postoperative complications (hazard ratio: 10.5, 95% confidence interval [1.01-109] P = .049) and steatosis (hazard ratio: 13.8, 95% confidence interval [1.23-154] P = .033) as predictors of death, and transfusion (hazard ratio: 19.2, 95% confidence interval [4.04-91.4] P < .001) and severe postoperative complications (hazard ratio: 4.07, 95% confidence interval [1.15-14.4] P = .030) as predictors of recurrence.Conclusion: The survival advantage of laparoscopic liver resection over open liver resection for intrahepatic cholangiocarcinoma is equivocal, given historical bias and missing data.
