Background: The UDP-glucuronosyltransferase 2 family polypeptide B17 (UGT2B17) detoxifies carcinogens found in tobacco smoke and ethanol in alcoholic drinks. Tobacco carcinogens and ethanol synergistically raise the risk for upper aero digestive tract (UADT) cancer (head and neck squamous carcinoma, and esophageal cancer). Deletion polymorphism of the UGT2B17 gene (UGT2B17-deletion) is a much more common copy number variant among Japanese than other populations. Thus, we conducted a nested and age/gender-matched case-control (1:1) study to determine if UGT2B17-deletion associates with cancer risk, including UADT-cancer in Japanese. Methods: Polymerase chain reaction was used to determine UGT2B17-deletion using DNA samples derived from peripheral blood or tumor tissue. Cases were cancer patients and controls were non-cancer patients. Nonconditional and conditional logistic regression analyses were performed. To overcome the issue of multiple-testing, Bonferroni correction was applied to set p < 0.003 as statistically significant. Results: A total of 3,092 patients were enrolled. UGT2B17-deletion was detected in 74% of the 1,887 non-cancer patients and 77% of the 1,205 cancer patients. UGT2B17-deletion was a significant risk factor for UADT-cancer development: odds ratio, 2.07; 95% confidence interval, 1.34 to 3.20, p=0.001. In contrast, UGT2B17-deletion was not a risk for any other type of cancers represented in our study population. Conclusions: These results suggest that UGT2B17-deletion may associate to increase the risk of UADT-cancer in Japanese.

- Abstract
Background: The C-reactive protein (CRP)-albumin-lymphocyte (CALLY) index is a novel immune nutrition scoring system associated with cancer prognosis. This study investigated the association between the CALLY index and the long-term outcomes of patients with gastric cancer., Methods: We included 175 patients with gastric cancer who underwent curative gastrectomies at the Department of Surgery, International University of Health and Welfare Hospital between January 2011 and October 2019. The CALLY index was calculated based on the levels of serum albumin, serum CRP, and peripheral lymphocyte count. Utilizing both univariate and multivariate analyses, the prognostic value of the CALLY index was investigated., Results: In the multivariate analyses, disease stage (hazard ratio [HR], 7.85; 95% confidence interval [CI], 3.31-18.6; P < .01), microvascular invasion (HR, 2.88; 95% CI, 1.30-6.36; P < .01), and low CALLY index (HR, 2.18; 95% CI, 1.00-4.76; P = .05) were independent and significant predictors of disease-free survival. Low body mass index (HR, 4.15; 95% CI, 1.63-10.6; P < .01), advanced disease stage (HR, 8.22; 95% CI, 3.47-19.5; P < .01), and low CALLY index (HR, 3.00; 95% CI, 1.3-6.93; P = .01) were independent and significant predictors of overall survival. The low CALLY index group had a lower body mass index ( P < .01), advanced disease stage ( P < .01), and a higher Glasgow prognostic score ( P < .01)., Conclusions: The CALLY index may be associated with a poor prognosis for gastric cancer, highlighting the utility of a comprehensive assessment using inflammatory, nutritional, and immunological statuses., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
Objectives: The prognostic significance of a high visceral fat area (VFA) in metastatic colorectal cancer (mCRC) remains unclear. We evaluated the prognostic impact of high-VFA on the long-term outcomes of patients with mCRC who underwent chemotherapy., Methods: Ninety patients with metastatic CRC who underwent chemotherapy were included. VFA measurement was performed by pre-treatment computed tomography using image analysis system. Overall survival (OS) and progression-free survival (PFS) rates were analyzed using the Cox proportional hazards model and Kaplan-Meier curves with the log-rank test., Results: High-VFA was identified in 39 patients. The OS (2-year OS rates: 51.6% vs 33.3%, p=0.0023) and PFS rates (2-year PFS rates: 18.0% vs 2.7%, p=0.012) were significantly lower in the high-VFA group than in the low-VFA group. In multivariate analysis, the independent significant predictors of OS were carbohydrate antigen 19-9 (CA19-9) ≥37.0 U/mL (HR: 1.99, 95%CI [1.20-3.31], p=0.007), Glasgow prognostic score (GPS) of 1 or 2 (HR: 2.65, 95%CI [1.53-4.58], p<0.001), and high-VFA (HR: 3.09, 95%CI [1.81-5.25], p<0.001). Similarly, the independent significant predictors of PFS were CA19-9 ≥37.0 U/mL (HR: 2.02, 95%CI [1.21-3.38], p=0.007), GPS of 1 or 2 (HR: 1.87, 95%CI [1.17-2.99], p=0.008), and high-VFA (HR: 2.65, 95% CI [1.61-4.35], p<0.001)., Conclusions: We demonstrated that pre-treatment high-VFA and high-GPS were significantly associated with worse OS and PFS rates in patients with mCRC who underwent chemotherapy., Competing Interests: Conflicts of Interest There are no conflicts of interest., (Copyright © 2024 The Japan Society of Coloproctology.)

- Abstract
Rationale: Complicated colorectal diverticulitis could be fatal, and an abscess caused by this complication is usually formed at the pericolic, mesenteric, or pelvic abscess. Therefore, we report a rare case of sigmoid colon diverticulitis that developed a large inguinal abscess., Patient Concerns: A woman in her 70s was admitted to our hospital with a chief complaint of left inguinal swelling and tenderness 1 week before admission. Physical examination showed swelling, induration, and tenderness in the left inguinal region. Blood tests revealed elevated inflammatory reaction with C-reactive protein of 11.85 mg/dL and white blood cells of 10,300/μL. Contrast-enhanced computed tomography showed multiple colorectal diverticula in the sigmoid colon, edematous wall thickening with surrounding fatty tissue opacity, and abscess formation with gas in the left inguinal region extending from the left retroperitoneum., Diagnoses: The diagnosis was sigmoid colon diverticulitis with large abscess formation in the left inguinal region., Interventions: Immediate percutaneous drainage of the left inguinal region was performed, as no sign of panperitonitis was observed. Intravenous piperacillin-tazobactam of 4.5 g was administered every 6 hours for 14 days., Outcomes: The inflammatory response improved, with C-reactive protein of 1.11 mg/dL and white blood cell of 5600/μL. Computed tomography of the abdomen confirmed the disappearance of the abscess in the left inguinal region, and complete epithelialization of the wound was achieved 60 days after the drainage. The patient is under observation without recurrence of diverticulitis., Lessons: We report a rare case of sigmoid colon diverticulitis that developed a large inguinal abscess, which was immediately improved by percutaneous drainage and appropriate antibiotics administration., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2024 the Author(s).

- Abstract
Introduction: Stenosis is a serious complication associated with stomas. The initial treatment for stoma stenosis is mainly the finger-bougie technique or balloon dilatation, and recurrence requires stomal reconstruction. However, the use of local triamcinolone injections for treating stoma stenosis has not been reported. Herein, we reported a case of repeated stoma stenosis in a high-risk patient in whom balloon dilatation combined with local triamcinolone injection effectively avoided stomal reconstruction., Presentation of Case: A woman in her 70s was admitted to our hospital with the chief complaint of a positive fecal occult blood test and was diagnosed with Ra advanced rectal cancer. Owing to the presence of multiple comorbidities, a laparoscopic Hartmann procedure with D3 dissection was performed. The operative time was 165 min and the intraoperative blood loss was 5 mL. On postoperative day 2, the colostomy stump became discolored, and stoma necrosis was diagnosed, which was successfully treated conservatively, with no findings of stoma falling or peritonitis. Six months after surgery, late stoma stenosis causing colonic obstruction was diagnosed, and the finger-bougie technique and balloon dilatation were ineffective. To avoid reoperation under general anesthesia, balloon dilatation using a CRE™ PRO GI Wireguided (Boston Scientific) at 19 mm for 3 min combined with a 40 mg injection of local triamcinolone into the stoma orifice scar was successfully performed., Discussion: No restenosis was observed after treatment., Conclusion: Balloon dilatation combined with local triamcinolone injections may be effective for recurrent stoma stenosis in patients with high-risk comorbidities after rectal cancer surgery., Competing Interests: Conflict of interest statement There are no conflicts of interest., (Copyright © 2024 The Authors.

- Abstract
Background/aim: This study evaluated the prognostic impact of vertebral fractures (VFs) on the survival of patients with colorectal cancer (CRC)., Patients and Methods: We included 299 patients with stage I-III CRC who had undergone elective surgery. The patients were divided into the VF group (n=94) and non-VF group (n=205). VFs were assessed using sagittal computed tomography image reconstruction (Th11-L5) performed preoperatively. Disease-free survival (DFS) and overall survival (OS) rates were analyzed., Results: The VF group had lower 5-year DFS and OS rates compared to the non-VF group (both, p<0.001). The independent predictors of DFS were carbohydrate antigen 19-9 (CA19-9) ≥37.0 ng/ml, T3/T4 disease, stage III CRC, osteopenia, and VF; for OS, CA19-9 ≥37.0 ng/ml, stage III, osteopenia, and VF. VF, compared with osteopenia, was a more significant prognostic factor for DFS and OS in patients with stage I+ II CRC (both, p<0.001)., Conclusion: Preoperative VF was associated with worse DFS and OS following CRC resection., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

- Abstract
Introduction: Gastric cancer has been reported to occur with mild to moderate mucosal atrophy, particularly after the eradication of Helicobacter pylori ( HP ) more than 10 years previously. However, no conclusion has been reached on how many years of esophagogastroduodenoscopy should be performed after HP eradication., Presentation of Case: This was a case of gastric carcinoma of the fundic gland type (GCFGT) 32 years after the eradication of HP , which is the longest posteradication period reported. A 62-year-old male patient was diagnosed with GCFGT after HP eradication and regular esophagogastroduodenoscopy, which revealed a white raised lesion on the anterior wall of the upper part of the body. Endoscopic submucosal dissection was performed for GCFGT, and the vertical and horizontal margins were negative., Clinical Discussion: In this case, HP was eradicated in 1990, and GCFGT developed 32 years later. To the best of our knowledge, this is the longest case in which gastric cancer appeared after HP eradication. HP eradication therapy for a duodenal ulcer was first reported in 1990, supporting that this is the longest case., Conclusions: This is the first case of gastric cancer more than 20 years after the eradication of HP . The endoscopic findings of this case are typical of GCFGT and may be useful when encountering such cases in the future. Therefore, the risk of gastric cancer should be considered for an extended period even after the eradication of HP , and regular esophagogastroduodenoscopy is recommended even after the eradication of HP ., Competing Interests: The authors declare no conflicts of interest.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2024 The Author(s).

- Abstract
Objectives: Parastomal hernia (PSH) is a common complication of colostomy; however, its risk factors remain poorly investigated. In this study, we examined the associations between sarcopenia, visceral and subcutaneous fat, and PSH in patients who underwent transperitoneal colostomy for colorectal cancer., Methods: This retrospective, single-center, cohort study included 60 patients who underwent laparoscopic or robot-assisted abdominoperineal resection or Hartmann's procedure for colorectal cancer between November 2010 and February 2022. Stoma creation was uniformly performed using the transperitoneal approach, and PSH was diagnosed via abdominal computed tomography (CT) at 1 year postoperatively. Visceral fat areas (VFAs) and subcutaneous fat areas (SFAs) were measured through preoperative CT images using an image analysis system. Risk factors for PSH were retrospectively analyzed., Results: PSH was diagnosed in 13 (21.7%) patients. In the univariate analysis, PSH was significantly associated with body mass index >22.3 kg/m
2 ( p =0.002), operation time >319 min ( p =0.027), estimated blood loss >230 mL ( p =0.008), postoperative complications ( p =0.028), stoma diameter >18.6 mm ( p =0.015), VFA >89.2 cm2 ( p =0.005), and SFA >173.2 cm2 ( p =0.001). Multivariate analyses confirmed that SFA >173.2 cm2 (odds ratio: 16.7, 95% confidence interval 1.29-217.2, p =0.031) was an independent risk factor for PSH., Conclusions: Subcutaneous fat area is significantly associated with the development of PSH after transperitoneal colostomy. Applying these insights could help to prevent PSH., Competing Interests: Conflicts of Interest There are no conflicts of interest., (Copyright © 2024 The Japan Society of Coloproctology.)- Published

- Abstract
A meta-analysis suggested that marine n -3 polyunsaturated fatty acids (PUFAs), e.g., eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), might reduce cancer mortality. However, a randomized clinical trial of marine n -3 PUFA and vitamin D supplementation failed to verify this benefit. This study aimed to investigate the potential interaction between vitamin D supplementation and serum EPA and DHA levels. This post hoc analysis of the AMATERASU trial (UMIN000001977), a randomized controlled trial (RCT), included 302 patients with digestive tract cancers divided into two subgroups stratified by median serum levels of EPA + DHA into higher and lower halves. The 5-year relapse-free survival (RFS) rate was significantly higher in the higher half (80.9%) than the lower half (67.8%; hazard ratio (HR), 2.15; 95% CI, 1.29-3.59). In the patients in the lower EPA + DHA group, the 5-year RFS was significantly higher in the vitamin D (74.9%) than the placebo group (49.9%; HR, 0.43; 95% CI, 0.24-0.78). Conversely, vitamin D had no effect in the higher half, suggesting that vitamin D supplementation only had a significant interactive effect on RFS in the lower half ( p for interaction = 0.03). These results suggest that vitamin D supplementation may reduce the risk of relapse or death by interacting with marine n -3 PUFAs.

- Abstract
We evaluated the usefulness of a newly devised tumor marker index (TMI), namely, the geometric mean of normalized carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9), in determining colorectal cancer (CRC) prognosis. This retrospective cohort study included 306 patients with stages I-III CRC who underwent elective laparoscopic resection between April 2010 and March 2020. Survival rates and risk factors of relapse-free survival (RFS) and cancer-specific survival (CSS) were analyzed using Kaplan-Meier curves and Cox proportional hazards model. High-TMI group (122 patients) had significantly lower rates (95% confidence interval [95% CI]) for 5-year RFS (89.7%, 83.9-93.5 vs. 65.8%, 56.3-73.8, p < 0.001) and CSS (94.9%, 89.4-97.6 vs. 77.3%, 67.7-84.4, p < 0.001) than low-TMI group. Multivariate analysis (hazard ratio [95% CI]) indicated ≥ T3 disease (RFS: 2.69, 1.12-6.45, p = 0.026; CSS: 7.64, 1.02-57.3, p = 0.048), stage III CRC (RFS: 3.30, 1.74-6.28, p < 0.001; CSS: 6.23, 2.04-19.0, p = 0.001), and high TMI (RFS: 2.50, 1.43-4.38, p = 0.001; CSS: 3.80, 1.63-8.87, p = 0.002) as significant RFS and CSS predictors. Area under the curve (AUC) of 5-year cancer deaths (0.739, p < 0.001) was significantly higher for TMI than for CEA or CA19-9 alone. Preoperative TMI is a useful prognostic indicator for patients with resectable CRC., (© 2024. The Author(s).)

- Abstract
Objective: The prognostic significance of a low visceral fat area (VFA) in colorectal cancer (CRC) remains unclear. The aim of this study was to evaluate the prognostic effects of a low VFA on the long-term outcomes of patients with CRC after laparoscopic surgery., Methods: This retrospective study included 306 patients with stages I-III CRC who underwent R0 resection. VFA was preoperatively measured via computed tomography using image processing software. Relapse-free survival (RFS) and overall survival (OS) rates were analyzed using the Cox proportional hazards model and Kaplan-Meier curves., Results: Low VFA was identified in 153 patients. The low VFA group had significantly lower RFS and OS rates than did the high VFA group (5-y RFS rates: 72 versus 89%, P = 0.0002; 5-y OS rates: 72 versus 92%, P = 0.0001). The independent significant predictors of RFS were T3 or T4 disease (hazard ratio [HR], 2.75; 95% confidence interval [CI], 1.12-6.76; P = 0.027), stage III CRC (HR, 3.49; 95% CI, 1.82-6.69; P < 0.001), low psoas muscle index (PMI; HR, 2.12; 95% CI, 1.19-3.79; P = 0.011), and low VFA (HR, 2.12; 95% CI, 1.16-3.86; P = 0.014). The independent significant predictors of OS were age ≥65 y (HR, 2.59; 95% CI, 1.13-5.92, P = 0.024), carbohydrate antigen 19-9 levels ≥37 ng/mL (HR, 2.32; 95% CI, 1.18-4.58; P = 0.015), stage III CRC (HR, 2.66; 95% CI, 1.37-5.17; P = 0.004), low PMI (HR, 2.00; 95% CI, 1.06-3.77; P = 0.031), and low VFA (HR, 2.42; 95% CI, 1.24-4.70; P = 0.009)., Conclusion: A low preoperative VFA was significantly associated with worse RFS and OS rates in patients who underwent CRC resection., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

- Abstract
Background: This prospective case series analyzed patients who underwent indocyanine green (ICG) fluorescent lymphography during open inguinal hernia repair. The aim of this study was to investigate the association between ICG leakage and postoperative hydroceles in patients who underwent inguinal hernia repair., Materials and Methods: Data were analyzed from 40 patients who underwent primary open hernia repair between October 2020 and June 2021 (44 cases in total). Hydroceles were categorized into two types: symptomatic and "ultrasonic" (detected only by ultrasound imaging)., Results: In the univariate analysis, hernia type (p = 0.044) and ICG leakage (p = 0.007) were independent risk factors for postoperative ultrasonic hydroceles. Additionally, mesh type (p = 0.043) and ICG leakage (p = 0.025) were independent risk factors for postoperative symptomatic hydroceles. In the multivariate analysis, ICG leakage (p = 0.034) was an independent risk factor for postoperative ultrasonic hydroceles., Conclusions: ICG leakage after inguinal hernia repair was independently associated with postoperative ultrasonic and symptomatic hydroceles. These findings suggest a relationship between lymphatic vessel injury and the incidence of postoperative hydroceles., (© 2023.

- Abstract
Background/aim: Symptomatic mediastinal goitre requires surgery and is usually resectable using the cervical approach alone; however, sternotomy is occasionally required. Sternotomy is a highly invasive procedure, and its complications, including mediastinitis and osteomyelitis, can be critical. To date, there have been no reports of non-invasive techniques to avoid sternotomy for mediastinal thyroid tumours. We investigated the safety and efficacy of thyroidectomy using the clavicle lifting technique with a paediatric Kent hook., Patients and Methods: This was a retrospective study of 8 patients who underwent thyroidectomy with a clavicle lifting technique between November 2014 and July 2021 at the Department of Surgery, International University of Health and Welfare Hospital. The primary endpoint was sternotomy avoidance rate and R0 resection rate. An extension retractor used in paediatric surgery was used for the clavicle lifting technique., Results: Sternotomy avoidance rate and R0 resection rate were 100%. The mean operative time was 161±53.5 min, and the mean blood loss was 125.6±125.8 ml. There were no intraoperative or postoperative complications related to the clavicle lifting technique., Conclusion: Thyroidectomy with a clavicle lifting technique for mediastinal goitre and thyroid cancer is safe and useful because it avoids sternotomy without causing massive intraoperative bleeding or damage to other organs., (Copyright © 2023, International Institute of Anticancer Research (Dr. George J.

- Abstract
Although elevated serum levels of soluble CD40 ligand (sCD40L) were reported in patients with cancer, the importance of high sCD40L levels in clinical oncology remains unknown. We conducted a post hoc analysis of the AMATERASU randomized clinical trial of vitamin D3 supplementation (2000 IU/day) in patients with digestive tract cancer to assess its significance. Serum sCD40L levels were measured by ELISA in 294 residual samples, and were divided into tertiles. In patients with colorectal cancer (CRC), 5-year relapse-free survival (RFS) rates in the middle and highest tertiles were 61.6% and 61.2%, respectively, which was significantly lower than 83.8% in the lowest tertile. A Cox proportional hazard analysis showed that the lowest tertile had a significantly lower risk of relapse or death than the highest tertile even with multivariate adjustment (hazard ratio (HR), 0.30; 95% confidence interval (CI), 0.11-0.80; p = 0.016). In the subgroup of CRC patients with the highest tertile of sCD40L, the 5-year RFS rate in the vitamin D group was 77.9%, which was significantly higher than 33.2% in the placebo group (HR, 0.30; 95% CI, 0.11-0.81; p = 0.018 [ P
interaction = 0.04]). In conclusion, elevated sCD40L might be a biomarker of poor prognosis in patients with CRC, but vitamin D supplementation might improve RFS in patients with high sCD40L.- Published

- Abstract
Background and study aims We have previously reported on the effectiveness of colonoscopy-assisted percutaneous sigmoidopexy (CAPS) for sigmoid volvulus treatment. This study describes the CAPS application to treat complete rectal prolapse by straightening and fixing the rectum. Complete rectal prolapse is common in older women. Due to their comorbidities, management must comprise a simple, safe, and reliable surgical method not involving general anesthesia or colon resection. Patients and methods We enrolled 13 patients in our outpatient department diagnosed with complete rectal prolapse between June 2016 and 2021. The endoscope was advanced into the anterior proximal rectal wall, straightening the intussuscepted sigmoid colon and rectum to approximate the puncture site. The fixation sites were anesthetized with 1% xylocaine, and a 2-mm skin incision was made using a scalpel. A two-shot anchor was used to fix the sigmoid colon to the abdominal wall (Olympus, Tokyo, Japan). Results The median patient age was 88 years (range: 50-94). The median CAPS procedure time was 30 minutes (range: 20-60). In one patient, the transverse colon was accidentally punctured and interposed between the abdominal wall and sigmoid colon, requiring a laparotomy to remove the causative fixation thread and provide re-fixation. Fecal incontinence was resolved in 10 of 13 cases. Conclusions CAPS is a quick and simple procedure. In addition, it is a treatment option for complete rectal prolapse that can be performed under local anesthesia., Competing Interests: Conflict of Interest The authors declare that they have no conflict of interest., (The Author(s).

- Abstract
Background: The conventional near-infrared fluorescent clip (NIRFC) ZEOCLIP FS® has been used successfully in marking tumour sites during laparoscopic surgeries. However, this clip is difficult to observe with the Firefly imaging system equipped with the da Vinci® surgical system. We have been involved in the modification of ZEOCLIP FS® and development of da Vinci-compatible NIRFC. This is the first prospective single-centre case series study verifying the usefulness and safety of the da Vinci-compatible NIRFC., Methods: Twenty-eight consecutive patients undergoing da Vinci®-assisted surgery for gastrointestinal cancer (16 gastric, 4 oesophageal, and 8 rectal cases) between May 2021 and May 2022 were enrolled., Results: Tumour location was identified by the da Vinci-compatible NIRFCs in 21 of 28 (75%) patients, which involved 12 gastric (75%), 4 oesophageal (100%), and 5 rectal (62%) cancer cases. No adverse events were observed., Conclusion: Tumour site marking with da Vinci-compatible NIRFC was feasible in 28 patients enrolled in this study. Further studies are warranted to substantiate the safety and improve the recognition rate., (© 2023. The Author(s).)

- Abstract
Purpose: The prognostic significance of the cachexia index, a novel biomarker of cancer cachexia, remains unclear in colorectal cancer; we, therefore, evaluated this relationship., Methods: This retrospective cohort study included 306 patients with stage I-III colorectal cancer who underwent R0 resection between April 2010 and March 2020. The cachexia index was calculated as (skeletal muscle index [cm
2 /m2 ] × serum albumin level [g/dL])/neutrophil-to-lymphocyte ratio. The overall and disease-free survival rates were analyzed using a Cox proportional hazards model., Results: A low cachexia index was found in 94 patients. This group had significantly lower disease-free survival and overall survival than the high-cachexia index group (5-year survival, 86.3% vs. 63.1%, p < 0.01; 87.9% vs. 67.2%, p < 0.01). Multivariate analyses showed that T3 or T4 (hazard ratio [HR]: 2.56; 95% confidence interval CI 1.04-6.25, p = 0.039), stage III (HR: 3.77; 95% CI 1.79-7.93, p < 0.01), and a low cachexia index (HR: 2.27; 95% CI 1.31-3.90, p = 0.003) were significant independent predictors of the disease-free survival. CA19-9 ≥ 37.0 ng/mL (HR: 2.68; 95% CI: 1.37-5.24, p = 0.004), stage III (HR: 2.57; 95% CI 1.34-4.92, p = 0.004), and a low cachexia index (HR: 2.35; 95% CI 1.31-4.21, p = 0.004) were significant independent predictors of the overall survival., Conclusion: A low cachexia index might be a long-term prognostic factor of colorectal cancer., (© 2023.

- Abstract
Importance: Recent meta-analyses of randomized clinical trials found that daily vitamin D3 supplementation had beneficial effects on cancer mortality, although the results are still controversial., Objective: To examine whether vitamin D supplementation reduces the risk of relapse or death in a supgroup of patients with digestive tract cancer who were p53 immunoreactive., Design, Setting, and Participants: This was a post hoc subgroup analysis of the AMATERASU randomized, double-blind, placebo-controlled clinical trial. This trial included patients at a single university hospital in Japan with digestive tract cancers between January 2010 and February 2018 followed up for a median (IQR) of 3.5 (2.5-5.3) years to compare the effects of vitamin D supplementation with placebo and was reported in 2019. Patients from among 417 participants in the AMATERASU trial whose residual serum samples were available were included. Data were analyzed from October 20 to November 24, 2022., Interventions: Vitamin D3 (2000 IU/d) supplementation or placebo., Main Outcomes and Measures: The primary outcome was 5-year relapse or death. The subgroup of patients who were p53 immunoreactive was defined by positivity for anti-p53 antibodies in serum and nuclear accumulation of p53 oncosuppressor protein in more than 99% of cancer cells, which is considered a biomarker for p53 missense mutations. Anti-p53 antibody levels were measured using chemiluminescent enzyme immune assay. Immunohistochemical staining data of p53 protein in cancer tissue in pathologic specimens were obtained from a previous study and divided into 4 grades., Results: Among 392 patients with digestive tract cancer (mean [SD] age, 66 [10.7] years; 260 males [66.3%]), there were 37 patients with esophageal cancer (9.4%), 170 patients with gastric cancer (43.4%), 2 patients with small bowel cancer (0.5%), and 183 patients with colorectal cancer (46.7%). Serum anti-p53 antibody was detectable in 142 patients (36.2%), and p53-immunohistochemistry grade showed a positive association with serum anti-p53 antibody levels (coefficient = 0.19; P < .001). In the p53-immunoreactive subgroup (80 patients), relapse or death occurred in 9 of 54 patients (16.7%) in the vitamin D group and 14 of 26 patients (53.8%) in the placebo group; 5-year relapse-free survival (RFS) was significantly higher in the vitamin D group (13 patients [80.9%]) than the placebo group (1 patient [30.6%]; hazard ratio [HR], 0.27; 95% CI, 0.11-0.61; P = .002). This was significantly different from 272 patients in the non-p53 immunoreactive subgroup, in which vitamin D had no effect on 5-year RFS (vitamin D: 35 of 158 patients [22.2%] vs placebo: 24 of 114 patients [21.1%]; HR, 1.09; 95% CI, 0.65-1.84) (P for interaction = .005)., Conclusions and Relevance: This study found that vitamin D supplementation reduced the risk of relapse or death in the subgroup of patients with digestive tract cancer who were p53 immunoreactive., Trial Registration: Identifier: UMIN000001977.

- Abstract
Injury to the right gastroepiploic artery (RGEA) graft during gastrectomy after coronary artery bypass grafting (CABG) can cause critical coronary failure. A man in his 60s with advanced gastric cancer and a history of CABG was admitted to our hospital. His cardiac blood flow was dependent on RGEA, and a gastrectomy with RGEA preservation was necessary. Robot-assisted distal gastrectomy with real-time vessel navigation using indocyanine green (ICG) fluorescence imaging and Da Vinci Firefly technology was planned. Intraperitoneal observation revealed severe adhesions around the graft. Two milliliters ICG (2.5 mg/mL) was injected intravenously, and RGEA was visualized. An RGEA-preserving robot-assisted distal gastrectomy was successfully performed. The operation time was 279 minutes, and the blood loss was 5 mL. The postoperative course was good and there were no complications., (© 2023 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

- Abstract
Metastasis from small-cell lung cancer to the colon is very rare. A 74-year-old man without respiratory or abdominal symptoms underwent a follow-up lower gastrointestinal endoscopy after a polypectomy. He was diagnosed with a 5 mm IIa non-hyperplastic polyp in the cecum and underwent a cold snare polypectomy. The histopathological findings confirmed the diagnosis of small cell carcinoma. The tumor was positive in the deep margins of the submucosal layer. Subsequent systemic examination revealed a mass in the lower lobe of the left lung. Thus, the tumor in the cecum was determined to be a colorectal metastasis from primary small-cell carcinoma of the lung. Metastasis to the colon was diagnosed as small-cell lung cancer based on local positivity for thyroid transcription factor-1 and morphologic and immunochemical features. To our best knowledge, this is the first report of colon metastasis from small cell carcinoma identified by endoscopic treatment., Competing Interests: None., (© 2023 The Authors.

- Abstract
Diagnosing the invasion depth of ulcerated early gastric cancer is usually inaccurate, especially for endoscopists in primary care clinics who are often not experts in this area. In reality, many patients with open ulcers who can be treated with endoscopic submucosal dissection (ESD) are referred for surgery., Materials and Methods: Twelve patients with ulcerated early gastric cancer who were treated with proton pump inhibitors, including vonoprazan, and underwent ESD were included in the study. Conventional endoscopic and narrow-band images were evaluated by five board-certified endoscopists (two physicians: A, B, and three gastrointestinal surgeons: C, D, and E). They assessed the invasion depth, and the results were compared with the pathologic diagnosis., Results: The accuracy of the invasion depth diagnosis was 38.3%. According to the pretreatment diagnosis of invasion depth, gastrectomy was recommended for 41.7% (5/12) of the cases. However, histological examination revealed that additional gastrectomy was required in only one case (8.3%). Thus, in four out of five patients unnecessary gastrectomy could be avoided. Post-ESD mild melena occurred in only one case, and there was no case of perforation., Conclusion: Antiacid treatment contributed to avoid unnecessary gastrectomy in four out of five patients for whom gastrectomy was indicated based on an inaccurate pretreatment diagnosis of the invasion depth., Competing Interests: None., (Copyright © 2023 The Author(s).

- Abstract
Introduction and Importance: Indocyanine green (ICG) fluorescent lymphography is reportedly a safe and effective method to diagnosis of lymphatic leakage. We report a case of a patient who underwent ICG fluorescent lymphography during laparoscopic inguinal hernia repair., Case Presentation: A 59-year-old man was referred to our department for the treatment of both inguinal hernias, during which laparoscopic ICG lymphography was performed. The patient had a history of open left inguinal indirect hernia repair at the age of 3 years. Following the induction of general anesthesia, 0.25 mg ICG was injected into both testicles, and the scrotum was gently massaged, after which laparoscopic inguinal hernia repair was performed. During the operation, ICG fluorescence was observed in two lymphatic vessels in the spermatic cord. The ICG fluorescent vessels were injured only on the left side due to strong adhesion between lymphatic vessels and the hernia sac, possibly due to a previous operation. ICG leakage was observed on the gauze. Laparoscopic inguinal hernia repair (transabdominal preperitoneal approach [TAPP]) was performed. The patient was discharged 1 day postoperatively. He had a slight postoperative ultrasonic hydrocele only in the left groin that was detected at the follow-up clinic 9 days postoperatively during ultrasonic examination (ultrasonic hydrocele)., Clinical Discussion: We report the use of ICG fluorescent lymphography during laparoscopic inguinal hernia repair in a patient who developed a postoperative ultrasonic hydrocele., Conclusion: This case may indicate a relationship between lymphatic vessel injury and hydroceles., Competing Interests: Conflict of interest statement The authors declare that they have no competing interests., (Copyright © 2023 The Authors.

- Abstract
Intracorporeal esophagojejunostomy after total or proximal robot-assisted gastrectomy is technically more demanding than gastroduodenostomy and gastrojejunostomy for distal gastrectomy, as well as laparoscopic surgery. We have established a safe and simple esophagojejunostomy procedure using a liner stapler attached to the Da Vinci Surgical System and a barbed suture device., Patients and Methods: For esophagojejunostomy after total gastrectomy or proximal gastrectomy with double-tract reconstruction, we choose the "overlap method," in which entry holes were made at the left of the esophageal stump and at 5 cm of the anal side in antimesentric area of the jejunum, followed by anastomosis on the left of the esophagus using SureForm (blue 45 mm) and hand-sewing closure of the common entry hole with V-Loc. We analyzed the short-term surgical outcomes of all patients., Results: 23 patients underwent this reconstruction technique. None of the patients required any further open surgeries. The mean time to perform anastomosis was 24.7±2.8 min. The postoperative course was uneventful in 22 patients; a single patient developed minor anastomotic leakage (Clavien-Dindo grade 3), which was treated with conservative therapy employing a drainage tube., Conclusion: Our esophagojejunostomy method following robot-assisted gastrectomy is simple and feasible, with acceptable short-term outcomes, and could represent the procedure of choice for esophagojejunostomy., Competing Interests: The authors declare that they have no financial conflict of interest with regard to the content of this report., (Copyright © 2023 the Author(s).

- Abstract
Aim: Cachexia is associated with the morbidity and mortality of cancer patients. The cachexia index (CXI) is a novel biomarker of cachexia associated with the prognosis for certain cancers. This study analyzed the relationship between CXI with long-term outcomes of gastric cancer patients., Methods: We included 175 gastric cancer patients who underwent curative gastrectomy at our hospital between January 2011 and October 2019. The CXI was calculated using skeletal muscle index, serum albumin level, and neutrophil-to-lymphocyte ratio. The prognostic value of CXI was investigated by univariate and multivariate Cox hazard regression models adjusting for potential confounders., Results: In the multivariate analyses, tumor location (hazard ratio [HR], 0.23; 95% confidence interval [CI], 0.11-0.49; p < 0.01), disease stage (HR, 15.4; 95% CI, 4.18-56.1; p < 0.01), and low CXI (HR, 2.97; 95% CI, 1.01-8.15; p = 0.03) were independent and significant predictors of disease-free survival. Disease stage (HR, 9.88; 95% CI, 3.53-29.1; p < 0.01) and low CXI (HR, 4.07; 95% CI, 1.35-12.3; p < 0.01) were independent and significant predictors of overall survival. The low CXI group had a lower body mass index ( p = 0.02), advanced disease stage ( p = 0.034), and a lower prognostic nutritional index ( p < 0.01)., Conclusions: Cachexia index is associated with a poor prognosis for gastric cancer, suggesting the utility of comprehensive assessment using nutritional, physical, and inflammatory status., Competing Interests: The authors declare that they have no conflicts of interest., (© 2023 The Authors.

- Abstract
The initial appearance of malignant melanoma localized in the stomach has never been reported previously. We encountered a patient with gastric melanoma in the stomach, which was histologically confirmed to be confined to the mucosa., Case Presentation: The patient, when in her 40s, had undergone surgery for malignant melanoma of the left heel. However, there were no detailed records of pathological findings. The patient had a 4-mm black elevated lesion in her stomach observed on esophagogastroduodenoscopy after the eradication of Helicobacter pylori. A year later, esophagogastroduodenoscopy showed that the lesion had increased to 8 mm. A biopsy was performed, but no malignancy was found; the patient continued to be followed up. Esophagogastroduodenoscopy performed at the 2-year follow-up revealed that the melanotic lesion had increased to 15 mm, and biopsy was performed and revealed a malignant melanoma., Clinical Discussion: Endoscopic submucosal dissection was performed for gastric malignant melanoma. The margin of the resected malignant melanoma was negative; vascular and lymphatic invasions were not observed, and the lesion was confined to the mucosa., Conclusion: We suggest that even if the first biopsy of a melanotic lesion shows no evidence of malignancy, the lesion should be closely monitored. This is the first reported case of endoscopic submucosal dissection of localized gastric malignant melanoma confined to the mucosa., Competing Interests: The authors declare that they have no financial conflict of interest with regard to the content of this report., (© 2023 the Author(s).

- Abstract
The most common site of traditional serrated adenomas (TSA) is the area from the left colon to the rectum; however, there are few reports on TSA in the small intestine. Herein, we report a case of TSA of the ileum with intussusception that was diagnosed and successfully treated with laparoscopic bowel resection. The patient was a 29-year-old female with the chief complaint of recurrent abdominal pain and vomiting. Contrast-enhanced computed tomography showed a mass in the ileum and intussusception with the mass as the lead point. The patient was diagnosed with intussusception secondary to a small intestinal tumor. Due to the difficulty in endoscopic treatment resulting from the localization of the lesion, elective laparoscopic surgery was planned. Intra-abdominal examination revealed intussusception of the small intestine in the pelvic ileum, and an elastic soft mass 400 cm from the ligament of Treitz was identified at the lead point of intussusception. Partial laparoscopic resection of the small intestine was performed, with an operation time of 81 min, and a small amount of bleeding. The pathological diagnosis was TSA of the ileum, and the patient's postoperative course was good, with no complications. Seven months after the surgery, no recurrence of symptoms was observed. Therefore, from our case of TSA of the ileum with intussusception that was successfully treated with laparoscopic bowel resection, we conclude that when intussusception of the small intestine occurs, TSA of the ileum with malignant potential is possible, and early diagnosis by resection should be considered., Competing Interests: The authors declare that they have no competing interests., (© 2023 The Author(s).

- Abstract
Background: Enterocutaneous fistula after removal of the jejunostomy tube leads to multiple problems, such as cosmetic problems, decreased quality of life, electrolyte imbalances, infectious complications, and increased medical costs. However, the risk factors for refractory enterocutaneous fistula (REF) after button jejunostomy removal remain unclear. Therefore, in this study, we assessed the risk factors for REF after button jejunostomy removal in patients with oesophageal cancer and reported the surgical outcomes of the novel extraperitoneal approach (EPA) for REF closure., Methods: This retrospective cohort study included 47 patients who underwent button jejunostomy removal after oesophagectomy for oesophageal cancer. We assessed the risk factors for REF in these patients and reported the surgical outcomes of the novel EPA for REF closure at the International University of Health and Welfare Hospital between March 2013 and October 2021. The primary endpoint was defined as the occurrence of REF after removal of the button jejunostomy, which was assessed using a maintained database. The risk factors and outcomes of the EPA for REF closure were retrospectively analysed., Results: REFs occurred in 15 (31.9%) patients. In the univariate analysis, REF was significantly more common in patients with albumin level < 4.0 g/dL (p = 0.026), duration > 12 months for button jejunostomy removal (p = 0.003), and with a fistula < 15.0 mm (p = 0.002). The multivariate analysis revealed that a duration > 12 months for button jejunostomy removal (odds ratio [OR]: 7.15; 95% confidence interval [CI]: 1.38-36.8; p = 0.019) and fistula < 15.0 mm (OR: 8.08; 95% CI: 1.50-43.6; p = 0.002) were independent risk factors for REF. EPA for REF closure was performed in 15 patients. The technical success rate of EPA was 88.2%. Of the 15 EPA procedures, fistula closure was achieved in 12 (80.0%). The complications of EPA (11.7%) were major leakages (n = 3) and for two of them, EPA procedure was re-performed, and closure of the fistula was finally achieved., Conclusion: This study suggested that duration > 12 months for button jejunostomy removal and fistula < 15.0 mm are the independent risk factors for REF after button jejunostomy removal. EPA for REF closure is a novel, simple, and useful surgical option for patients with REF after oesophagectomy., (© 2022. The Author(s).)

- Abstract
Background: A significant difference exists between the reported optimal timing of indocyanine green (ICG) injection during fluorescence cholangiography and ICG dissipation time from the serum. There are no reports on alterations in ICG concentration in biliary fluid over time. Herein, we measured the concentration of ICG and the fluorescence intensity ratio between the common bile duct (CBD) and liver, which was recognized as a parameter of the visibility of the CBD., Materials and Methods: ICG (0.05 mg/kg) was injected intravenously into female pigs (n = 7). Afterwards, the fluorescence of the CBD and liver was detected at 30 min, 2 h, and 4 h. Biliary fluid was collected from cannulated CBD tubes. The fluorescence intensity was measured using captured images and calculated using the ImageJ image-processing program. ICG concentration was measured using spectrophotometry and compared using an analysis of variance test., Results: Biliary ICG concentrations at 30 min, 2 h, and 4 h were 92.07 ± 27.72 μg/mL, 37.14 ± 9.76 μg/mL (p < 0.05 vs. 30 min), and 13.91 ± 5.71 μg/mL (p < 0.05 vs. 30 min), respectively; p < 0.01. The CBD/liver fluorescence intensity ratios at 30 min, 2 h, and 4 h were 1.25 ± 0.72, 2.39 ± 1.28 (p < 0.05 vs. 30 min and 4 h), and 3.38 ± 1.73 (p < 0.05 vs. 30 min and 2 h), respectively., Conclusions: The ICG biliary concentration was highest at 30 min, whereas the CBD/liver fluorescence intensity ratio was highest at 4 h. Decreasing the fluorescence intensity of the liver may be an important approach for improving the visualization of the CBD during fluorescence cholangiography., Institutional Protocol Number: PE/EA/491-5/2020., Competing Interests: The authors have no conflicts of interest to declare., (© 2022 The Authors.)

- Abstract
Colonoscopy-assisted percutaneous sigmoidopexy is a simple and swift procedure that does not require general anesthesia. While we first developed this procedure for treating sigmoid volvulus, we herein present the first case in which we used it to correct a complete rectal prolapse in an older patient. Existing treatment modalities for rectal prolapses are limited by high recurrence rates, greater invasiveness, and greater complications; thus, there is a need for minimally invasive techniques that are associated with lower recurrence rates and fewer complications. In this case, a woman in her 90s complained of persistent fecal incontinence, dysuria, anal pain, and difficulty in walking. She was diagnosed with a complete rectal prolapse of 15 cm and was treated with colonoscopy-assisted percutaneous sigmoidopexy. The sigmoid colon was tractioned colonoscopically and fixed to the abdominal wall to immobilize the prolapsed rectum. The patient developed no complications intraoperatively and postoperatively and experienced no recurrence during a 5-year postoperative period. This report documents the first case wherein colonoscopy-assisted percutaneous sigmoidopexy was used successfully to correct a complete rectal prolapse., Competing Interests: None., (© 2022 The Authors.

- Abstract
Introduction: The existing treatment methods for rectal prolapse still have problems in terms of their recurrence, invasiveness, and complications; hence, minimally invasive techniques with fewer recurrences and complications are necessary. We performed laparoscopic sigmoidopexy to the abdominal wall to treat complete rectal prolapse., Presentation of Case: An Asian woman in her 80s presented with a complaint of constant faecal and urinary incontinence. She was diagnosed with a 4 cm complete rectal prolapse and underwent surgery. The sigmoid colon was tractioned laparoscopically and fixed to the abdominal wall. The patient had no intraoperative or postoperative complications, and her defaecation was well-controlled without recurrence for one year after surgery., Discussion: In this study, we performed laparoscopic sigmoidopexy to the abdominal wall with good results., Conclusion: This simple method, which requires only five sutures, can be a candidate treatment method for complete rectal prolapse., Competing Interests: Declaration of competing interest There are no conflicts of interest., (Copyright © 2022 The Authors.

- Abstract
Sarcopenia affects the swallowing and chewing muscles, such as the masseter muscle. However, the significance of masseter muscle loss in pneumonia remains unclear. We investigated the effects of masseter muscle sarcopenia (MMS) on postoperative pneumonia in patients with esophageal cancer. In this retrospective cohort study, we analyzed the data of 86 patients who underwent esophagectomy for stage I-III esophageal cancer at our hospital between March 2013 and October 2021. The primary endpoint was postoperative pneumonia within 3 months of surgery. MMS was defined as a (1) masseter muscle index (MMI) that was less than the sex-specific MMI cutoff values, and (2) sarcopenia diagnosed using the L3-psoas muscle index (L3-PMI). Postoperative pneumonia was noted in 27 (31.3%) patients. In multivariate analysis, FEV
1.0 < 1.5 L (odds ratio, OR: 10.3; 95% confidence interval, CI 1.56-67.4; p = 0.015), RLNP (OR: 5.14; 95%CI 1.47-17.9; p = 0.010), and MMS (OR: 4.83; 95%CI 1.48-15.8; p = 0.009) were independent risk factors for postoperative pneumonia. The overall survival was significantly worse in patients with pneumonia (log-rank: p = 0.01) than in those without pneumonia. Preoperative MMS may serve as a predictor of postoperative pneumonia in patients with esophageal cancer., (© 2022. The Author(s).)- Published

- Abstract
Background: Appendicectomy is generally a minimally invasive surgery, after which postoperative complications such as acute respiratory distress syndrome (ARDS) are rare. We describe a case of ARDS due to sepsis caused by Bacteroides ovatus after appendicectomy., Case Presentation: A man in his 60 s presented to our hospital with a chief complaint of right lower quadrant abdominal pain. He was diagnosed with acute appendicitis and underwent emergency laparoscopic appendicectomy. Cefmetazole was administered as a perioperative antibacterial drug. Postoperatively, the abdominal findings improved. However, on postoperative day three, bloody sputum and respiratory distress were observed. We performed thoracoabdominal computed tomography (CT) and observed bilateral pleural effusion and mottled frosted glass shadows extending to both lung fields. ARDS was diagnosed. We treated the patient with steroids and sivelestat sodium and switched the antibacterial drug to meropenem. The patient's general condition improved. After the patient was treated, Bacteroides ovatus was isolated from preoperative blood culture, which was resistant to cefmetazole., Conclusions: We encountered a case in which ARDS due to sepsis was caused by Bacteroides ovatus after acute appendicectomy. Blood culture to isolate the causative organism and determine its antimicrobial sensitivity after commencement of empiric antibiotics is important even in common diseases, such as acute appendicitis., (© 2022.

- Abstract
Some controversy remains on thresholds for deficiency or sufficiency of serum 25-hydroxyvitamin D (25(OH)D) levels. Moreover, 25(OH)D levels sufficient for bone health might differ from those required for cancer survival. This study aimed to explore these 25(OH)D threshold levels by applying the machine learning method of multivariable adaptive regression splines (MARS) in post hoc analyses using data from the AMATERASU trial, which randomly assigned Japanese patients with digestive tract cancer to receive vitamin D or placebo supplementation. Using MARS, threshold 25(OH)D levels were estimated as 17 ng/mL for calcium and 29 ng/mL for parathyroid hormone (PTH). Vitamin D supplementation increased calcium levels in patients with baseline 25(OH)D levels ≤17 ng/mL, suggesting deficiency for bone health, but not in those >17 ng/mL. Vitamin D supplementation improved 5-year relapse-free survival (RFS) compared with placebo in patients with intermediate 25(OH)D levels (18−28 ng/mL): vitamin D, 84% vs. placebo, 71%; hazard ratio, 0.49; 95% confidence interval, 0.25−0.96; p = 0.04. In contrast, vitamin D supplementation did not improve 5-year RFS among patients with low (≤17 ng/mL) or with high (≥29 ng/mL) 25(OH)D levels. MARS might be a reliable method with the potential to eliminate guesswork in the estimation of threshold values of biomarkers.

- Abstract
Background: The conventional near-infrared fluorescence clip (NIRFC): ZEOCLIP FS®, was difficult to observe using the Firefly on da Vinci. We improved the ZEOCLIP FS® and produced the da Vinci compatible NIRFC. In this report, we describe a robot-assisted wedge resection of a submucosal tumour (SMT) of the stomach using the da Vinci compatible NIRFC., Presentation of Case: Surgery was performed for an enlarging SMT (from 18 to 22 mm with an intragastric growth type). Through endoscopy, four da Vinci-compatible NIRFCs were placed at the tumour edge two days prior to the surgery. The location of the NIRFC was confirmed when observed with the Firefly. The distal NIRFC site was incised with a monopolar shear blade to identify the NIRFCs and tumour base. The open area was sutured in two layers using a 3-0 V-Loc. The operation time was 83 min, and the amount of blood loss was 2 g. There were no complications or clip dropout., Discussion: This method could be performed without intraoperative endoscopist., Conclusion: In this case, we were able to observe the position of the da Vinci-compatible NIRFC with Firefly on da Vinci. This technique may be an option as a simple procedure to minimize the resection area of the stomach., (Copyright © 2022 The Authors. Published by Elsevier Ltd.. All rights reserved.)

- Abstract
Severe duodenal ulcer stenosis requires continuous decompression, which makes oral ingestion difficult, yet poor nutritional status before surgery increases the risk postoperative complications. Double percutaneous transesophageal gastrotubing (dPTEG) is a new treatment that provides both decompression and enteral nutrition. We report a case of duodenal ulcer scar stenosis in which dPTEG was used for preoperative management. A man in his 40s visited our hospital with vomiting as a chief complaint. CT scan showed duodenal ulcer stenosis. As the existence of malignant disease could not be ruled out, surgery was planned. Before surgery, dPTEG was inserted to achieve decompression and nutritional management. The patient's gastric distension and nutritional status improved significantly, and laparoscopic distal gastrectomy was performed 22 days after the insertion. dPTEG may be an effective management method for patients with pyloric stenosis due to duodenal ulcer., (© 2022 The Authors.
