RESUMO
BACKGROUND: Calculous gall bladder disease is often handled by laparoscopic cholecystectomy. In cases where a safe dissection of the hepatocystic triangle cannot be carried out, a subtotal cholecystectomy (STC) may be performed. The perioperative management of patients undergoing STC is characterized by limited evidence. This large single-center series explores some of the perioperative aspects and outcomes after STC. MATERIALS AND METHODS: The study population includes all patients who underwent STC at Oslo University Hospital (Ullevål and Aker Hospitals) from 01.01.2014 to 30.09.2020. A STC was defined as a cholecystectomy where there was a failure to control the cystic duct during surgery. Study variables included demographic data, comorbidities, previous biliopancreatic disease, indication for surgery, perioperative information, subsequent interventions and outcome data. RESULTS: During the study period, 2376 cholecystectomies were performed, and 102 (4.3%) were categorized as STC. Of all patients with STC, 48 (47.1%) had an intra- or postoperative ERCP during the index hospital admission. The indication for ERCP was bile leak in 37 (42.6%) of the cases. The bile leak resolution rate was 60.0 % in intraoperative ERCP vs 95.7% in postoperative ERCP. Among the STC patients, there were no injuries to the central bile ducts. Later, one patient has undergone a remnant cholecystectomy, following fenestrating STC. CONCLUSION: STC was a safe bailout strategy for dissection in the hepatocystic triangle in difficult cholecystectomies. Intraoperative ERCP increased procedure time and was associated with a lower rate of leak resolution, as compared to postoperative ERCP.

Anastomotic leakage (AL) is a dreaded complication following esophageal resection. No clear consensus exist for the optimal handling of this severe complication. The aim of this study was to describe the treatment outcome following AL. We conducted a retrospective cross-sectional study including all patients with AL operated with Ivor Lewis esophagectomy from 2010 to 2021 at Oslo University Hospital, Norway. 74/526 (14%) patients had AL. Patient outcomes were analyzed and categorized according to main AL treatment strategy; stent (54%), endoscopic vacuum therapy and stent (EVT + stent) (19%), nasogastric tube and antibiotics (conservative) (16%), EVT (8%) and by other endoscopic means (other) (3%). One patient had surgical debridement of the chest cavity. In 66 patients (89%), the perforation healed after median 27 (range: 4-174) days. Airway fistulation was observed in 11 patients (15%). Leak severity (ECCG) was associated with development of airway fistula (P = 0.03). The median hospital and intensive care unit stays were 30 (range: 12-285) and 9 (range: 0-60) days. The 90-days mortality among patients with AL was 5% and at follow up, 13% of all deaths were related to AL. AL closure rates were comparable across the groups, but longer in the EVT + stent group (55 days vs. 29.5 days, P = 0.04). Thirty-two percent developed a symptomatic anastomotic stricture within 12 months. Conclusion: The majority of AL can be treated endoscopically with preservation of the conduit and the anastomosis. We observed a high number of AL-associated airway fistulas.

Esophagectomy is a complex and complication laden procedure. Despite centralization, variations in perioparative strategies reflect a paucity of evidence regarding optimal routines. The use of nasogastric (NG) tubes post esophagectomy is typically associated with significant discomfort for the patients. We hypothesize that immediate postoperative removal of the NG tube is non-inferior to current routines. All Nordic Upper Gastrointestinal Cancer centers were invited to participate in this open-label pragmatic randomized controlled trial (RCT). Inclusion criteria include resection for locally advanced esophageal cancer with gastric tube reconstruction. A pretrial survey was undertaken and was the foundation for a consensus process resulting in the Kinetic trial, an RCT allocating patients to either no use of a NG tube (intervention) or 5 days of postoperative NG tube use (control) with anastomotic leakage as primary endpoint. Secondary endpoints include pulmonary complications, overall complications, length of stay, health related quality of life. A sample size of 450 patients is planned (Kinetic trial: https://www.isrctn.com/ISRCTN39935085). Thirteen Nordic centers with a combined catchment area of 17 million inhabitants have entered the trial and ethical approval was granted in Sweden, Norway, Finland, and Denmark. All centers routinely use NG tube and all but one center use total or hybrid minimally invasive-surgical approach. Inclusion began in January 2022 and the first annual safety board assessment has deemed the trial safe and recommended continuation. We have launched the first adequately powered multi-center pragmatic controlled randomized clinical trial regarding NG tube use after esophagectomy with gastric conduit reconstruction.

Background: Common bile duct stones occur in 2-12 % of all patients who undergo laparoscopic cholecystectomy. Laparoscopic transcystic extraction of bile duct stones as a one-step procedure is an alternative to endoscopic retrograde cholangiopancreatography (ERCP), with comparable success and complication rates. The study aimed to survey the clinical course in patients who underwent transcystic stone extraction and cholecystectomy simultaneously. Material and method: All patients who underwent transcystic stone extraction in conjunction with laparoscopic cholecystectomy at Oslo University Hospital, Ullevål in the period 1 January 2019 to 30 November 2023 were registered. Results: The study included 23 patients, of whom 16 were women and 7 were men. Five patients had previously undergone a Roux-en-Y gastric bypass. A total of 20 patients had undergone surgery with gallstones as the indication. Transcystic stone extraction was successful in 22 patients. The median length of surgery (range) was 190 (115-302) minutes. Three patients developed mild complications related to the procedure. The median number of hospital bed days following the operation was 1 (range: 1-22). Interpretation: Laparoscopic transcystic stone extraction in conjunction with cholecystectomy may be a good alternative treatment for common bile duct stones and appears to be associated with few complications.

OBJECTIVE: To gain insight in global practice of RAMIG and evaluated perioperative outcomes using an international registry. BACKGROUND: The techniques and perioperative outcomes of robot-assisted minimally invasive gastrectomy (RAMIG) for gastric cancer vary substantially in literature. METHODS: Prospectively registered RAMIG-cases for gastric cancer (≥10 per center) were extracted from 25 centers in Europe, Asia and South-America. Techniques for the resection, reconstruction, anastomosis and lymphadenectomy were analyzed, and related to perioperative surgical and oncological outcomes. Complications were uniformly defined by the Gastrectomy Complications Consensus Group. RESULTS: Between 2020-2023, 759 patients underwent total (n=272), distal (n=465) or proximal (n=22) gastrectomy (RAMIG). After total gastrectomy with Roux-en-Y-reconstruction, anastomotic leakage rates were 8% with hand-sewn (n=9/111) and 6% with linear stapled anastomoses (n=6/100). After distal gastrectomy with Roux-en-Y (67%) or Billroth-II-reconstruction (31%), anastomotic leakage rates were 3% with linear stapled (n=11/433) and 0% with hand-sewn anastomoses (n=0/26). Extent of lymphadenectomy consisted of D1+ (28%), D2 (59%) or D2+ (12%). Median nodal harvest yielded 31 nodes [IQR 21-47] after total and 34 nodes [IQR 24-47] after distal gastrectomy. R0-resection rates were 93% after total and 96% distal gastrectomy. Hospital stay was 9 days after total and distal gastrectomy, and was 3 days shorter without perianastomotic drains versus routine drain placement. Postoperative 30-day mortality was 1%. CONCLUSIONS: This large multicenter study provided a worldwide overview of current RAMIG-techniques with their respective perioperative outcomes. These outcomes demonstrated high surgical quality, set a quality standard for RAMIG and can be considered an international reference for surgical standardization.
RESUMO
AIM: The aim was to explore potential associations between the body mass index (BMI) and the risk of colorectal cancer (CRC), including subsites of the colon, and cancer-specific death. METHODS: A registry-based cohort study was conducted with baseline data gathered from the Norwegian Tuberculosis Screening Programme, collected between 1963 and 1975, and linked to follow-up data from the Cancer Registry of Norway and the Norwegian Cause of Death Registry. Cox regression models were used to explore associations between BMI and CRC risk and cancer-specific death. RESULTS: Of 1 723 692 included individuals, 76 616 developed CRC during 55 370 707 person-years of follow-up. In men, a 5 kg/m2 increase in BMI was associated with an increased risk of colon cancer, including both right and left subsites, and rectal cancer. Allowing for nonlinearities, we found a U-shaped association for the right colon and an inverse U-shape for the left colon and rectum cancer. In women, a 5 kg/m2 increase in BMI in early adulthood was associated with increased risk of colon cancer, including both subsites. In women, an increased risk of CRC death with increasing BMI was found for colon cancer. CONCLUSIONS: Men of all ages have an increased risk of CRC with increasing BMI, with the highest risk for right-sided colon cancer. An increased risk for colon cancer was also found in women with high BMI in early adulthood. Furthermore, women of all age groups appeared to have an increased risk of CRC death with higher BMI.

BACKGROUND: The aim of this study was to explore the associations between BMI and cancer of the liver, bile ducts, and gallbladder. METHODS: A registry-based cohort study was performed by linking data from several national registries in Norway. RESULTS: The cohort comprised 1 723 692 individuals including 4768 hepatobiliary cancer cases during 55 743 509 person-years of follow-up. In men, we found increased risk of cancer per 5 kg/m2 BMI increase for hepatocellular carcinoma and extrahepatic cholangiocarcinoma. In women there was increased risk of extrahepatic cholangiocarcinoma and gallbladder cancer. Women with high BMI in early adulthood had increased risk of intrahepatic cholangiocarcinoma. Reduced cancer-specific survival was found for all hepatobiliary malignancies in women with overweight and obesity. In men, reduced survival was observed in individuals with obesity for all hepatobiliary cancers, except gallbladder cancer. Increased risk of cancer-death per 5 kg/m2 BMI increase was found for hepatocellular carcinoma, intra-, and extrahepatic cholangiocarcinoma in women. For men, 5 kg/m2 BMI increase was positively associated with cancer-death from intrahepatic cholangiocarcinoma. DISCUSSION: This study supports the notion of an increased risk of hepatobiliary cancers with increasing BMI, with sex and age variations. The findings also suggest a higher risk of cancer-death with increasing BMI.
RESUMO
BACKGROUND: Mini-gastric bypass is a new surgical method for the treatment of morbid obesity. The method was introduced at Oslo University Hospital in 2016. MATERIAL AND METHOD: We performed a retrospective analysis of prospective data collected over a two-year period following mini-gastric bypass between 1 March 2016 and 1 April 2021. RESULTS: Altogether, 241/1611 (15 %) patients who underwent surgery at the Centre for Morbid Obesity in the five-year period received a mini-gastric bypass. A total of 147/241 (61 %) met the inclusion criteria and 125/147 (85 %) were included in the study. Average age was 47.4 years (standard deviation 10.7), and 81/125 (64.8 %) were women. Average weight was 134 (25) kg before and 90 (20) kg after surgery. Total average weight loss two years after surgery was 33.1 % (9.1). Before surgery and two years post-surgery, 20.0 % and 27.2 % had gastroesophageal reflux, 38.3 % and 8.8 % had type II diabetes and 84.8 % and 44.0 % had dyslipidaemia, respectively. Altogether, 12 % developed anaemia, 6.3 % iron deficiency and 23.1 % vitamin D deficiency. Early complications (< 30 days) were recorded in 6/125 (4.8 %) patients and late complications (> 30 days) in 7/125 (5.6 %) patients. The results were comparable to all the quality indicators in the Scandinavian Obesity Surgery Registry Norway. INTERPRETATION: Mini-gastric bypass can be performed with few complications and with a beneficial effect on secondary comorbidity up to two years after surgery.

OBJECTIVE: To provide the first international comparison of oesophageal and gastric cancer survival by stage at diagnosis and histological subtype across high-income countries with similar access to healthcare. METHODS: As part of the ICBP SURVMARK-2 project, data from 28 923 patients with oesophageal cancer and 25 946 patients with gastric cancer diagnosed during 2012-2014 from 14 cancer registries in seven countries (Australia, Canada, Denmark, Ireland, New Zealand, Norway and the UK) were included. 1-year and 3-year age-standardised net survival were estimated by stage at diagnosis, histological subtype (oesophageal adenocarcinoma (OAC) and oesophageal squamous cell carcinoma (OSCC)) and country. RESULTS: Oesophageal cancer survival was highest in Ireland and lowest in Canada at 1 (50.3% vs 41.3%, respectively) and 3 years (27.0% vs 19.2%) postdiagnosis. Survival from gastric cancer was highest in Australia and lowest in the UK, for both 1-year (55.2% vs 44.8%, respectively) and 3-year survival (33.7% vs 22.3%). Most patients with oesophageal and gastric cancer had regional or distant disease, with proportions ranging between 56% and 90% across countries. Stage-specific analyses showed that variation between countries was greatest for localised disease, where survival ranged between 66.6% in Australia and 83.2% in the UK for oesophageal cancer and between 75.5% in Australia and 94.3% in New Zealand for gastric cancer at 1-year postdiagnosis. While survival for OAC was generally higher than that for OSCC, disparities across countries were similar for both histological subtypes. CONCLUSION: Survival from oesophageal and gastric cancer varies across high-income countries including within stage groups, particularly for localised disease. Disparities can partly be explained by earlier diagnosis resulting in more favourable stage distributions, and distributions of histological subtypes of oesophageal cancer across countries. Yet, differences in treatment, and also in cancer registration practice and the use of different staging methods and systems, across countries may have impacted the comparisons. While primary prevention remains key, advancements in early detection research are promising and will likely allow for additional risk stratification and survival improvements in the future.

BACKGROUND: Few European centers have reported on robotic gastrectomy for malignancy. We report our early experience with curative-intent total robotic gastrectomy. MATERIALS AND METHODS: The Intuitive Surgery Da Vinci Surgical System Xi 4 armed robot was used. Routine D2 lymphadenectomy was applied. RESULTS: Some 27 patients with adenocarcinoma (n = 18), hereditary cancer susceptibility (n = 8) and premalignancy (n = 1) were allocated to robotic gastrectomy, three were excluded due to inoperability during surgery. Median (range) age was 66 (18-87) years, 14 (58.3%) were females and body mass index was 25.5 (22.1-33.5) kg/m2. Total gastrectomy was performed in 19 (79.2%) and subtotal in five (20.8%) patients. One (4.2%) procedure was converted to laparotomy. Procedural time was 273 (195-427) minutes. Three (12.5%) patients were reoperated within 30 days, one (4.2%) died. Serious complications (Clavien Dindo IIIb or more) occurred in three (12.5%) patients. Postoperative hospital stay was 10 (6-43) days. Fourteen of 16 (87.5%) patients with adenocarcinoma/premalignancy received radical resections. The median number of harvested lymph nodes was 20 (11-34). Eleven (73.3%) patients with adenocarcinoma had T3/T4 tumors and 6 (40%) had TNM stage III or more. CONCLUSION: Total robotic D2 gastrectomy appears feasible and safe during early introduction in a low incidence region.

OBJECTIVE: The aim of this study was to compare the use and short-term outcome of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in Sweden, Norway, and the Netherlands. BACKGROUND: Although bariatric surgery is performed in high volumes worldwide, no consensus exists regarding the choice of bariatric procedure for specific groups of patients. METHODS: Data from 3 national registries for bariatric surgery were used. Patient selection, perioperative data (severe complications, mortality, and rate of readmissions within 30 days), and 1-year results (follow-up rate and weight loss) were studied. RESULTS: A total of 47,101 primary operations were registered, 33,029 (70.1%) RYGB and 14,072 (29.9%) SG. Patients receiving RYGB met international guidelines for having bariatric surgery more often than those receiving SG (91.9% vs 83,0%, P < 0.001). The 2 procedures did not differ in the rate of severe complications (2.6% vs 2.4%, P = 0.382), nor 30-day mortality (0.04% vs 0.03%, P = 0.821). Readmission rates were higher after RYGB (4.3% vs 3.4%, P < 0.001).One-year post surgery, less RYGB-patients were lost-to follow-up (12.1% vs 16.5%, P < 0.001) and RYGB resulted in a higher rate of patients with total weight loss of more than 20% (95.8% vs 84.6%, P < 0.001). While the weight-loss after RYGB was similar between hospitals, there was a great variation in weight loss after SG. CONCLUSION: This study reflects the pragmatic use and short-term outcome of RYGB and SG in 3 countries in North-Western Europe. Both procedures were safe, with RYGB having higher weight loss and follow-up rates at the cost of a slightly higher 30-day readmission rate.

BACKGROUND: Patients who have undergone Roux-en-Y gastric bypass (RYGB) are at increased risk of biliary disease necessitating endoscopic retrograde cholangiopancreatography (ERCP). The most widely used approaches to perform ERCP after RYGB are laparoscopy-assisted ERCP (LA-ERCP) and balloon enteroscopy-assisted ERCP (BEA-ERCP). There are few studies comparing these procedures. We aimed to compare the performance, benefits, and harms of LA-ERCP and BEA-ERCP in RYGB patients. METHODS: We identified all RYGB patients who underwent ERCP at two tertiary care endoscopy centers in Oslo, Norway between May 2013 and December 2017. One center performed BEA-ERCP, the other LA-ERCP. Procedure success was defined as fulfillment of the therapeutic or diagnostic aim, according to the procedure description. Adverse events were classified according to the Clavien-Dindo grading system. RESULTS: During the study period, 40 BEA-ERCP and 39 LA-ERCP procedures were performed in 68 patients. Procedure success rate was 72.5â% for BEA-ERCP and 87.2â% for LA-ERCP (Pâ=â0.14). Adverse events occurred in 18â% of BEA-ERCP and 28â% of LA-ERCP (Pâ=â0.23). Serious adverse events (Clavien-Dindo gradeâ≥â3b) occurred in 2.5â% of BEA-ERCP and 7.7â% of LA-ERCP procedures (Pâ=â0.36). Concomitant cholecystectomy was performed in 25 of the 39 LA-ERCP procedures. The median procedure times for LA-ERCP performed with and without concomitant cholecystectomy were 201 minutes and 140 minutes, respectively, and for BEA-ERCP was 125 minutes. CONCLUSIONS: In experienced hands, both LA-ERCP and BEA-ERCP have high success rates after RYGB. The choice of approach should be individualized according to patient characteristics and available physician competence.

Hereditary ventricular polyposis in the form of gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS) is a rare condition characterised by a typical distribution of polyps in the stomach and risk of gastric cancer at a young age. Prophylactic gastrectomy may be indicated. The condition is not thought to be associated with increased risk of colon cancer, but the evidence base is limited.

BACKGROUND: Irritable bowel syndrome (IBS) is prevalent in patients with morbid obesity. After Roux-en-Y gastric bypass (RYGB) chronic abdominal pain is common, however the etiology is largely unknown. We aimed to study the change in the prevalence of IBS-like symptoms 2 years after RYGB and possible preoperative predictors of such symptoms. Secondly, to evaluate changes in symptoms of constipation and diarrhea, and Health related quality of life (HRQoL). METHODS: Patients with morbid obesity were included at two obesity centers in South-Eastern Norway. IBS was diagnosed according to the Rome III criteria. Predictors were evaluated in a multivariable logistic regression analysis. RESULTS: Of 307 participants operated with RYGB, 233 (76%) completed the study questionnaires. Preoperatively 27/233 participants (12%) had IBS, 2 years after RYGB 61/233 (26%) had IBS-like symptoms (p < 0.001). Eleven participants with IBS preoperatively (41%) did not report such symptoms after RYGB. New onset IBS-like symptoms was identified in 45/206 (22%) after RYGB. Fibromyalgia, low LDL levels, high vitamin B1 levels and IBS before RYGB were independent preoperative predictors of IBS-like symptoms at the follow-up visit. Symptom scores for constipation preoperatively and 2 year after RYGB were 1.5 (0.9) and 1.8 (1.2), and for diarrhea 1.4 (0.9) and 1.8 (1.1), respectively (p < 0.001). We observed a significant improvement in the physical component score for all participants. However, participants with new onset IBS-like symptoms had a significant worsening of the mental component score. CONCLUSIONS: The prevalence of IBS-like symptoms doubled 2 years after RYGB, and these symptoms were associated with reduced HRQoL. Preoperative IBS and fibromyalgia were strong predictors of postoperative IBS-like symptoms.

BACKGROUND: Bariatric surgery has been performed at Oslo University Hospital since 2004. We wished to describe patient characteristics, use of surgical methods and perioperative complications in the period 2004-14. MATERIAL AND METHOD: We performed a retrospective analysis of prospective data collected for the period 2004-14. Complications include events during hospitalisation and up to 6-8 weeks postoperatively. RESULTS: Altogether 2 127 patients underwent surgery for morbid obesity, whereof 1 468 were women. Average age and body mass index were 42 years (range 17-73) and 46.2 kg/m2 (range 26-92). A total of 512 had a body mass index ≥ 50 kg/m2. Obesity-related sequelae were registered in 1 196 patients before surgery. Gastric bypass was performed in 1 966 patients, gastric sleeve resection in 122 (17 of these later underwent duodenal switch) and duodenal switch in 56 patients. All patients were operated laparoscopically, and four procedures were converted to laparotomy. Median hospitalisation time was two days (range 1-78). Complications were registered in 209 patients, 75 of whom had severe complications (grade ≥ IIIb on the Clavien-Dindo classification system). Patients with a body mass index ≥ 50 kg/m2 had a higher incidence of complications (12.5 % vs 8.9 %). Altogether 67 patients underwent further surgery. Six patients died, two of whom more than 30 days after the operation. The incidence of complications was reduced during the period. INTERPRETATION: Bariatric surgery may be performed laparoscopically with a low incidence of complications and short hospitalisation times. A large proportion of the patients who underwent surgery had obesity-related sequalae.

OBJECTIVE: The high prevalence of secondary hyperparathyroidism (SHPT) after obesity surgery is a concern for long-term bone health. Limited knowledge exists about optimal vitamin D and suppression of parathyroid hormone (PTH) after these procedures. The aim of this study was to investigate the prevalence of SHPT and its relation to vitamin D status. DESIGN: A cross-sectional study at Oslo University Hospital, Norway. PATIENTS: A total of 502 consecutive patients, age 22-64 years, attending 2-year follow-up after Roux-en-Y gastric bypass. MEASUREMENTS: A serum intact PTH >7.0 pmol/L in the absence of elevated serum ionized calcium (iCa) was considered as SHPT. Vitamin D status was defined by serum concentrations of 25-hydroxyvitamin D (S-25(OH)D). RESULTS: Altogether, 171 patients (34%) had SHPT. The prevalence of SHPT varied across the range of S-25(OH)D (P < 0.001), being highest (71%) with S-25(OH)D < 25 nmol/L. Compared with S-25(OH)D < 50 nmol/L, the prevalence of SHPT was lower with S-25(OH)D ≥ 50 nmol/L (29.0%; RR = 0.64 (95%-CI:0.50-0.81)) and S-25(OH)D ≥ 75 nmol/L (27.7%; RR = 0.61 (95%-CI:0.44-0.84)). S-25(OH)D ≥ 100 nmol/L was associated with the lowest PTH and the lowest prevalence of SHPT (16.0%; RR = 0.35 (95%-CI:0.14-0.88) compared with S-25(OH)D < 50 nmol/L) and the most normal calcium distribution. These associations were most pronounced with iCa in the lower range. A synergistic association was found for S-25(OH)D and iCa on SHPT. CONCLUSIONS: Vitamin D deficient patients had the highest prevalence of SHPT 2 years after gastric bypass. PTH and the prevalence of SHPT were notably lower with S-25(OH)D ≥ 100 nmol/L, compared with lower target levels.

PURPOSE: Plasma concentrations of several amino acids (AAs) are positively correlated with obesity. The aim of this study was to examine if selected plasma AAs are associated with weight regain from 2 to 4 years after Roux-en-Y gastric bypass (RYGB). METHODS: In a prospective study with 165 patients, we examined the relationship between plasma aromatic AAs (AAAs), branched chain AAs (BCAAs), and total cysteine (tCys) 2 years after RYGB, with BMI at 2 years and with weight change from 2 to 4 years after surgery. Analyses were adjusted for relevant covariates. RESULT: The investigated AAs at 2 years correlated positively with BMI at 2 years (P ≤ 0.003 for all). BCAAs and AAAs at 2 years correlated inversely with % weight loss from 0 to 2 years (P = 0.002 and P = 0.001, respectively), while the association was not significant for tCys (r = -0.14, P = 0.08). Plasma tCys at 2 years correlated positively with BMI at 4 years (P = 0.010) and with weight regain from 2 to 4 years (P = 0.015). CONCLUSION: Plasma AAAs, BCAAs, and tCys at 2 years were associated with BMI at 2 years. In addition, plasma AAAs and BCAAs at 2 years were associated with weight loss from 0 to 2 years, while tCys at 2 years was associated with weight regain from 2 to 4 years after RYGB. These results suggest that high tCys at 2 years may be used as a prognostic marker for future weight regain. The study was registered in ClinicalTrials.gov (NCT0 1270451).
