Background and Aims: The use of endoscopic treatment for early colorectal cancer (ECC) is increasing. The European guidelines suggest performing piecemeal endoscopic resection (pmR) for benign lesions and en bloc resection for ECC, especially for patients with favorable lymph node involvement risk evaluations. However, en bloc resections for lesions larger than two centimeters require invasive endoscopic techniques. Our retrospective single-center study aimed to determine the clinical impact of performing pmR for ECC rather than traditional en bloc resection. Methods: A single-center study was performed between January 2012 and September 2017. All ECC patients were included. The main objective was to evaluate the number of patients who potentially underwent unnecessary surgery due to piecemeal resection. The secondary endpoints were as follows: disease-free survival (DFS), defined as the time from pmR to endoscopic failure (local recurrence not treatable by endoscopy), complication rate, number of patients who did not undergo surgery by default, and factors predictive of outcomes and complications. Results: One hundred and forty-six ECC endoscopically treated patients were included. In total, 85 patients were excluded (71 who underwent en bloc resection, 14 with pending follow-up). Data from 61 patients (33 women and 28 men) were analyzed. Two patients underwent potentially unnecessary surgery [3.28% (0.9%- 11.2%)]. The DFS rate was 87% (75%-93%) at 6 months and 85% [72%-92%] at 12 months. The median follow- up time was 16.5 months (12.4-20.9). Three patients (4.9%) had complications. One patient did not undergo surgery by default. A Paris classification of 0-2c (HR=9.3 (2.4-35.9), p<0.001) and Vienna classification of 5 [HR=16.3 (3.3-80.4), p<0.001] were factors associated with poor DFS. Conclusion: Performing pmR in place of en bloc resection for ECC had a limited impact on patients. If the pathology (especially deep margins) is analyzable, careful monitoring could be acceptable in ECC patients who undergo pmR.

Long Term Follow Up

1 Background: With the progress in endoscopic submucosal dissection (ESD) which enables en bloc resection irrespective of the size of lesion, a therapeutic strategy has become feasible whereby ESD is undertaken first, followed by considering additional treatment based on the results of histologic exploration. In this study, we attempted to clarify the clinical results in patients who had undergone additional treatment after endoscopic resection (ER) for cN0 superficial carcinoma. Methods: Of 140 patients diagnosed as having T1a-MM-SM2 lesions of squamous cell carcinoma of the esophagus who had undergone ER between January 1998 and March 2010, 83 patients who received additional treatment after ER (surgery, 27 pts; chemoradiotherapy [CRT], 56 pts.) were the subjects of this study. The mean duration of observation was 45.1 months. Results: The en bloc resection rate was 86%. There were 5 patients (6%) who had complications associated with ER, including perforation in 2 patients, secondary hemorrhage in a patient and pneumonia in 2 patients. Complications associated with additional treatment were noted in 13 patients (15.6%), including secondary hemorrhage, recurrent laryngeal nerve paralysis and pulmonary infarction in one patient each, pneumonia in 3, grade ≥ 3 myelosuppression in 5, and syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and radiation pneumonitis in one patient each. Long-term follow-up revealed no local recurrence and no patients who experienced late toxicity due to CRT. The tumor recurred in 4 patients, the site of recurrent lesion being the mediastinum in 3 patients and the cervical lymph node in one patient, of whom 2 patients died of the primary disease. The 5-year survival rate was 88.4%. Conclusions: Endoscopic resection plus additional treatment for superficial carcinoma of the esophagus did not entail the development of any serious complications; thus, such combined treatment was safe and feasible. The long-term follow-up results were fairly gratifying, and ER with subsequent additional treatment is considered to be valid for patients with cN0 superficial carcinoma of the esophagus.

Abstract Background and study aims Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors in the gastrointestinal tract. Up to the present time, complete surgical excision has been the standard treatment for primary GISTs greater than 2 cm. It is well known that tumor rupture during surgery is an independent risk factor for peritoneal metastasis; however, it is not known whether the risk of peritoneal metastasis increases in cases where the tumor is ruptured during endoscopic resection. Patients and methods A total of 195 patients treated for GIST between January 2014 and December 2016 in our hospital were enrolled in this study. They were divided into two groups according to whether the tumor was ruptured during endoscopic resection. The rate of peritoneal metastasis in patients in the two groups who also suffered perforation was investigated from the follow-up results. Results Approximately 55.4 % of all patients were female and the average age of the study group was 59.0 ± 10.3 years. Of the 195 patients, the tumors in 27 were ruptured and the remaining 168 patients underwent en bloc resection. There was no statistically significant difference in gender or age between the two groups. The median tumor size (maximum diameter) in all patients was 1.5 cm (0.3 – 5.0 cm): 2.5 cm (0.8 – 5.0 cm) and 1.4 cm (0.3 – 4.0 cm) in the tumor rupture group and en bloc resection group, respectively (P < 0.001). Most of the tumors were located in the gastric fundus. At a median follow-up of 18.7 ± 10.2 months, neither tumor recurrence (liver metastasis, peritoneal metastasis, local recurrence) nor mortality related to GISTs were detected. Conclusions Tumor rupture during endoscopic resection of gastric GISTs may not be a risk factor for peritoneal metastasis.

Abstract Background The management of ampullary lesions has shifted from surgical approach to endoscopic resection. Previous reports were limited by small numbers of patients and short follow-up. The aim of this study is to describe short- and long-term outcomes in a large cohort of patients undergoing endoscopic ampullectomy. Methods Retrospective study of endoscopic ampullectomies performed at a tertiary center from January 1999 to October 2016. Information recorded includes patient demographics, clinical outcomes, lesion pathology, procedural events, adverse events and follow-up data. Results Overall, 103 patients underwent endoscopic resection of ampullary tumours (mean age 62.3 ± 14.3 years, 50.5% female, mean lesion size 20.9 mm; 94.9% adenomas, with a majority of lesions exhibiting low-grade dysplasia (72.7%). Complete endoscopic resection was achieved in 82.5% at initial procedure. Final complete endoscopic resection was achieved in all patients with benign pathology on follow-up procedures. Final pathology showed that 11% had previously undiagnosed invasive carcinoma. Delayed postprocedure bleeding occurred in 21.4%, all of which were managed successfully at endoscopy. Acute pancreatitis complicated 15.5% of procedures (mild in 93.8%). Perforation occurred in 5.8%, all treated conservatively except for one patient requiring surgery. Piecemeal resection was associated with significantly higher recurrence compared to en-bloc resection (54.3% versus 26.2%, respectively, P = 0.012). All recurrences were treated endoscopically. Conclusion Endoscopic ampullectomy appears both safe and effective in managing patients with ampullary tumours in experienced hands. Most adverse events can be managed conservatively. Many patients develop recurrence during long-term follow-up but can be managed endoscopically. Recurrence rates may be reduced by performing initial en-bloc resection.

Abstract Background and study aims Because superficial non-ampullary duodenal epithelial tumors (SNADETs) are relatively rare, studies evaluating the outcomes of endoscopic resection (ER) for SNADETs are limited. Therefore, this study aimed to evaluate the clinical validity of ER for SNADETs. Patients and methods The study participants included 163 consecutive patients (108 men; mean age, 61.5 ± 11.3 years) with 171 SNADETs, excluding patients with familial adenomatous polyposis resected by ER, at Hiroshima University Hospital between May 2005 and September 2016. Clinicopathological features and the outcomes of ER for 171 cases were retrospectively analyzed. Additionally, the prognosis of 135 patients with more than 12 months’ follow-up was analyzed. Results Mean diameter of SNADETs was 10.7 ± 7.2 mm. Most of the SNADET cases were classified as category 3 (71 %, 121/171), but some were category 5 (2 %, 3/171). En bloc resection rates were 93 % (146/157), 100 % (7/7), and 86 % (6/7) in endoscopic mucosal resection (EMR), polypectomy, and in endoscopic submucosal dissection (ESD) cases, respectively. Complete resection rates were 90 % (141/157), 100 % (7/7), and 71 % (5/7) in EMR, polypectomy, and ESD cases, respectively. Emergency surgery was performed in two patients with intraoperative perforation and in two with delayed perforation without artificial ulcer bed closure after ER. Since endoscopic closure of ulcer by clipping was performed, delayed perforation has not occurred. Local recurrence occurred in 1.2 %, but no metastasis to lymph nodes or other organs occurred after ER. No patient died of primary SNADETs. Conclusion Our data supported the clinical validity of ER for SNADETs. However, delayed perforation should be given much attention.

Abstract Background Proteinuria has been commonly reported in patients with COVID-19. However, only dipstick tests have been frequently used thus far. Here, the quantification and characterization of proteinuria were investigated and their association with mortality was assessed. Methods This retrospective, observational, single center study included 153 patients, hospitalized with COVID-19 between March 28th and April 30th, 2020, in whom total proteinuria and urinary α1-microglobulin (a marker of tubular injury) were measured. Association with mortality was evaluated, with a follow-up until May 7th, 2020. Results According to the Kidney Disease Improving Global Outcomes staging, 14% (n = 21) of the patients had category 1 proteinuria (< 150 mg/g of urine creatinine), 42% (n = 64) had category 2 (between 150 and 500 mg/g) and 44% (n = 68) had category 3 proteinuria (over 500 mg/g). Urine α1-microglobulin concentration was higher than 15 mg/g in 89% of patients. After a median follow-up of 27 [14;30] days, the mortality rate reached 18%. Total proteinuria and urinary α1-microglobulin were associated with mortality in unadjusted and adjusted models. This association was stronger in subgroups of patients with normal renal function and without a urinary catheter. Conclusions Proteinuria is frequent in patients with COVID-19. Its characterization suggests a tubular origin, with increased urinary α1-microglobulin. Tubular proteinuria was associated with mortality in COVID-19 in our restropective, observational study.
