for the CARTS Study Group IMPORTANCE Treatment of rectal cancer is shifting toward organ preservation aiming to reduce surgery-related morbidity. Short-term outcomes of organ-preserving strategies are promising, but long-term outcomes are scarce in the literature.OBJECTIVE To explore long-term oncological outcomes and health-related quality of life (HRQL) in patients with cT1-3N0M0 rectal cancer who underwent neoadjuvant chemoradiotherapy (CRT) followed by transanal endoscopic microsurgery (TEM). DESIGN, SETTING, AND PARTICIPANTSIn this multicenter phase II feasibility study, patients with cT1-3N0M0 rectal cancer admitted to referral centers for rectal cancer throughout the Netherlands between February 2011 and September 2012 were prospectively included. These patients were to be treated with neoadjuvant CRT followed by TEM in case of good response. An intensive follow-up scheme was used to detect local recurrences and/or distant metastases. Data from validated HRQL questionnaires and low anterior resection syndrome questionnaires were collected. Data were analyzed from February 2011 to April 2017. MAIN OUTCOMES AND MEASURESThe primary study outcome of the study was the number of ypT0-1 specimens by performing TEM. Secondary outcome parameters were locoregional recurrences and HRQL. RESULTSOf the 55 included patients, 30 (55%) were male, and the mean (SD) age was 64 (39-82) years. Patients were followed up for a median (interquartile range) period of 53 (39-57) months. Two patients (4%) died during CRT, 1 (2%) stopped CRT, and 1 (2%) was lost to follow-up. Following CRT, 47 patients (85%) underwent TEM, of whom 35 (74%) were successfully treated with local excision alone. Total mesorectal excision was performed in 16 patients (4 with inadequate responses, 8 with completion after TEM, and 4 with salvage for local recurrence). The actuarial 5-year local recurrence rate was 7.7%, with 5-year disease-free and overall survival rates of 81.6% and 82.8%, respectively. Health-related quality of life during follow-up was equal to baseline, with improved emotional well-being in patients treated with local excision (mean score at baseline, 72.0; 95% CI, 67.1-80.1; mean score at follow-up, 86.9; 95% CI, 79.2-94.7; P = .001). Major, minor, and no low anterior resection syndrome was experienced in 50%, 28%, and 22%, respectively, of patients with successful organ preservation. CONCLUSIONS AND RELEVANCEIn early-stage rectal cancer (cT1-3N0M0), CRT enables organ preservation with additional TEM surgery in approximately two-thirds of patients with good long-term oncological outcome and HRQL. This multimodality treatment triggers a certain degree of bowel dysfunction, and one-third of patients still undergo radical surgery and are overtreated by CRT.

The a-FRS predicts POPF after pancreatoduodenectomy based on 3 easily available variables (pancreatic texture, duct diameter, BMI) without blood loss and pathology, and was successfully validated for both the 2005 and 2016 POPF definition.

The aim of this study was to establish whether the pylorus-preserving pancreatoduodenectomy (PPPD) is a safe and radical procedure in malignant disease of the head of the pancreas and periampullary region, without increased morbidity and mortality rates compared with the standard Whipple's procedure. During the period 1984 to 1990, a Whipple's procedure (n = 44) or PPPD (n = 47) was performed in 91 patient. In-hospital mortality rates were 2% after PPPD and 5% after Whipple's procedure. Median duration of the resection procedure and median blood loss in the PPPD group were 210 minutes and 1800 mL, respectively. After Whipple's procedure, these figures were 255 minutes and 2500 mL, both significantly different (p less than 0.01) as compared with PPPD. No difference was found during follow-up with respect to days of gastric suctioning, start of liquid diet, normal diet, complaints of ulcer disease, postoperative complications, recurrence of disease, and survival. In all patients, curative resection was performed with comparable TNM (tumor, nodes, metastases) staging. The number of tumor-containing duodenal or gastric resection margins did not differ in both groups of patients (two patients after PPPD, two patients after Whipple's procedure). Hospital stay was significantly (p = 0.02) shorter after PPPD; median 14 days, compared with median 18 days after Whipple's procedure. The advantage of the PPPD is that it is an easier and less time-consuming operation, with less blood loss, a shorter hospital stay, and better weight gain (p = 0.02) during follow-up. In conclusion, PPPD is a safe and radical procedure for cancer in the head of the pancreas or periampullary region, with the same survival and appearance of locoregional recurrence and distant metastases as after standard Whipple's resection.
