RESUMO
We report a case of rectal cancer that was resected 1 year and 3 months after SEMS implantation. An 89-year-old man was previously diagnosed with sigmoid colon cancer at another hospital but did not undergo surgery. Three years and 7 months after the diagnosis, SEMS was implanted at another hospital. Four years and 10 months after the diagnosis, the patient was diagnosed with intestinal obstruction at our hospital. Since the SEMS was open on colonoscopy, the patient was also suspected of having flaccid constipation. The primary tumor was resected, and a colostomy was constructed in the descending colon. Bridge to surgery for obstructive colorectal cancer was performed within a few weeks after SEMS implantation. At our hospital, resection was performed after a long time. No complications, such as obstruction or perforation, were observed. In addition, although there were concerns regarding increased vascular invasion due to compression and drainage of the cancerous tissue, in our case, the vascular invasion was mild, and no distant metastasis or invasion of other organs was observed. SEMS can be used for long-term implantation and does not necessarily cause cancer progression.

Surgery for transverse colon cancer is very difficult because of small number of patients, variations in the vascular system, and complexity of the mobilize hepatic and splenic flexure of colon. We analyzed the clinical characteristics and surgical outcomes in 51 cases who underwent surgery for transverse colon cancer at our hospital between January 2014 and December 2021, and examined the optimal laparoscopic approach method. The surgical procedure was right hemicolectomy in 24 cases, transverse colectomy in 22 cases, and left hemicolectomy in 5 cases, of which 37 cases had laparoscopic surgery. In laparoscopic surgery, when comparing the cranial first approach group in 21 cases and the caudal approach group in 16 cases, the operative time was almost the same between the 2 groups. In the cranial first approach group the amount of bleeding tended to be small, the number of MCA lymph node dissections tended to be large and the hospital stay tended to be short, though there was no statistically significant difference. The results suggest that the cranial first approach tends to be safer and more accurate than the caudal approach.

We report a patient with inoperable hilar cholangiocarcinoma due to invasion at the umbilical portion who survived more than 4 years after right portal vein embolization and administration of S-1(50 mg/day). A 64-year-old male patient was immediately hospitalized for liver dysfunction and a high level of HbA1c. The disease was diagnosed as hilar cholangiocarcinoma mainly extending along the right hepatic duct. We made a request for operation to Nagoya University. He received right portal vein embolization in order to grow the residual liver but was deemed inoperable because of invasion at the umbilical portion. He refused chemotherapy but accepted administration of S-1(50 mg/day). Approximately 3 months after starting S-1, his ALP level normalized and about 9 months later stenting tube was lost. Subsequently, he returned to his job. Approximately 2 years and 2 months later, administration of S-1 was interrupted due to a harmful side effect. After approximately 13 months without S-1, the levels of CA19-9 and ALP again became elevated and administration of S-1 was restarted. He was temporarily hospitalized for abdominal pain and fever, but quickly recovered. Although CA19-9 and ALP levels re-normalized, he died after returning home. We emphasize the possibility of maintaining long-term health by minimal- dose S-1 therapy for inoperable hilar cholangiocarcinoma.

We report the y-shape+1 method, which is a retraction of the liver method, independent of the position of the costal arch. Additionally, we report changes in liver enzymes induced by different methods of liver retraction. Three Penrose No. 6 drains were cut into 6 cm pieces. Penrose 1 was fixed with a thread attached to the end and Penrose 2 in a y-shape. A knitting thread with needles was prepared, and a loop was made at the end of the thread. The needle thread was passed over the abdominal wall and through the Penrose 2. The needle thread was passed over the diaphragmatic leg and through the Penrose 3. The thread was pulled over the abdominal wall and diaphragmatic leg and fixed to the end of Penrose 1 out of the body, and the liver was drained. The rate of change in liver enzymes from the preoperative to postoperative stages was examined separately in the Penrose and Nathanson groups. In the y-shape+1 technique, retraction of the liver can be performed regardless of the position of the rib arch; however, intracorporeal suture ligation is necessary. This method is useful when the conventional Penrose method is inappropriate because of the position of the rib arch.

Non-ampullary duodenal tumors are relatively rare; however, in recent years, they have been encountered more frequently. We analyzed the surgical outcomes and clinicopathological findings in 20 patients who underwent surgery based on preoperative diagnoses of non-ampullary duodenal tumors at our hospital between January 2011 and April 2021. We performed surgery for 3 cases of GIST, 4 cases of adenoma, and 13 cases of adenocarcinoma. The average age of the patients was 64.3 years and the male-to-female ratio was 17:3. The location of the tumor was the blub in 5 cases, the superior duodenal angle in 2 cases, the descending portion in 9 cases, the horizontal portion in 3 cases, and the ascending portion in 1 case. The histological type of adenocarcinoma was tub1 in all cases of early cancer, whereas in advanced cancer, there were many cases with histological types other than tub1. Various surgical procedures from duodenal local resection to pancreatoduodenectomy can be performed for treating non-ampullary duodenal tumors depending on the tumor location and the necessity of lymph node dissection. It is important to establish a treatment policy that considers both curability and invasiveness.

Malignant esophageal stenosis adversely affects the quality of life(QOL)on account of poor oral intake. Endoscopic esophageal stenting is one of palliative therapy for improve QOL because of minimally invasive and simple procedure. We investigated the outcomes of esophageal stenting in our institution. Twenty patients with malignant esophageal stenosis who underwent esophageal stenting in our institution between April 2014 and December 2019 were included in this study. Six(30%)out of 20 patients showed fistula. Dysphagia score was improved significantly before and after stenting(3.3± 0.6 vs 1.8±0.9, p<0.01). Complications associated with stenting occurred in 6(30%)cases. Thirteen(65%)patients were able to be discharged from the hospital, but 7(35%)patients including 4 with fistula were outcomes of death in the hospital. Esophageal stenting for malignant esophageal stenosis improved food ingestion and QOL. The prognosis in the case of malignant esophageal stenosis with fistula is extremely poor.

We herein report a case of application of sugar to the edematous stoma for obstructive rectal cancer. A 70-year-old male patient was diagnosed with rectal cancer, bowel obstruction and multiple lung metastases. Colostomy was performed. Seven days after operation, severe edema and congestion of stoma continued. We started spraying of sugar to stoma, and a few days later, edema and congestion of stoma improved. Before discharge, stoma size markedly reduced. Steady state of stoma and achievement the ability to self-care their stoma is important for introduction of chemotherapy. Application of sugar to reduce edema of rectal prolapse and prolapsed stoma have reported. Although the number of reported cases is still small, effectiveness of sugar to reduce edema of stoma have reported. In our case, application of sugar to the stoma is effective in reduction of edema. Application of sugar might be effective in reduction edema of stoma.

TAS-102 has been administered to patients with unresectable colorectal cancer. We initiated TAS-102 administration in 2014 and gradually increased the number of indications. In a global, multicenter, randomized, double-blind, phase III study (RECOURSE study), TAS-102 administration improved overall survival by 1.8 months and progression-free survival by 0.3 months compared with those in the placebo group. However, there are limited clinical reports of long-term administration of TAS-102. We encountered 2 cases of continuous long-term use of the TAS-102 for over 2 years. In our cases, although the cancer had been recognized early as exhibiting slow growth during follow-up, the physical symptoms did not appear for an extended period. Although grade 3 neutropenia was pointed out several times during the follow-up term, severe digestive symptoms had not occurred. Therefore, the patients could remain motivated to receive the drug. In our cases, the adequate treatment for neutropenia enabled long-term administration of TAS-102; therefore, TAS-102 would be tolerable for patients of colorectal cancer after receiving chemotherapy for an extended period.

BACKGROUND: Epidural analgesia or paravertebral block is widely used in postoperative analgesia for video-assisted thoracic surgery (VATS). We investigated the efficacy of the continuous intravenous infuion of fentanyl combined with intercostal nerve block, in comparison with the continuous epidural analgesia. METHODS: Forty-one patients received a bolus of 0.375% ropivacaine 6-10 ml through the epidural catheter placed at the T5-9 at the end of surgery. Then, continuous epidural infusion of 0.2% ropivacaine at a rate of 4 or 6 ml x hr(-1) was started (Group E). 44 patients received intercostal nerve block at three insertion points of thoracoscopy (using 0.75% ropivacaine 3-4 ml, respectively) at the end of surgery. Then, continuous intravenous infusion of fentanyl at a rate of 0.5 µg x kg(-1) x hr(-1) was started (Group F). The efficacy of post-operative analgesia was evaluated by additional analgesic requirements. RESULTS : There was no significant difference in the additional analgesic requirements between the two groups. However, the additional analgesics were required significantly earlier in Group E than Group F (P < 0.05). CONCLUSIONS: Continuous intravenous infusion of fentanyl combined with intercostal nerve block is effective in the postoperative analgesia for VATS, as well as continuous epidural analgesia.

BACKGROUND: Perioperative delirium increases the morbidity and mortality in elderly patients. The present retrospective study was carried out to evaluate whether desflurane or sevoflurane has influence on the incidence of perioperative delirium. METHODS: In 30 patients above 75 years of age undergoing surgical procedure, anesthesia was maintained with sevoflurane (group S), and with desflurane (group D). The incidence of perioperative delirium was obtained retrospectively from their medical chart The delirium was diagnosed with the Richmond agitation-sedation scale. RESULTS: The incidence of perioperative delirium on postoperative day (POD) 1-3 was not significantly different between group D and group S. The patients in group D were discharged earlier about 10 days compared with those group S. CONCLUSIONS: Desflurane anesthesia is same as sevoflurane regarding perioperative delirium in elderly patients. Shorter hospitalization in group D was achieved for 10 days compared with those in group S, due to the lower incidence of delirium on POD 3 and 5 in group D.

INTRODUCTION: Collagenous colitis is an inflammatory disease characterized by hyperplasia of the collagen band beneath the colonic mucous membrane. Chronic diarrhea is a characteristic clinical symptom. The disease is often diagnosed accidentally on colonoscopy for chronic diarrhea, and patients without chronic diarrhea have few chances to suspect the disease. PRESENTATION OF CASE: The patient was a 75-year-old woman. The chief complaint was sudden upper abdominal pain and vomiting. There were no important findings regarding the consumed food or bowel habits (no diarrhea). Computed tomography revealed wall thickness and a small amount of free air around the descending colon. An emergency laparotomy was performed with the diagnosis of spontaneous colonic perforation. Intra-operative findings revealed a longitudinal ulcer and micro-perforation to the mesenterial side at the descending colon. Pathological findings revealed subepithelial collagenous band in the submucosal background of the ulcer, and which was diagnosed as collagenous colitis. DISCUSSION: Intestinal perforation in collagenous colitis is extremely rare. It was considered that perforation was caused by a transient increase in intestinal pressure in the background of collagenous colitis. Further, to the best of our knowledge, this is the first report of a critical case which presented without the characteristic symptom of chronic diarrhea. CONCLUSION: We report a rare case of colonic perforation of the collagenous colitis.
RESUMO
Endovascular transarterial embolization is the standard treatment for the nonsinus-type of dural arteriovenous fistulae. Here, we report a rare case of successful transarterial embolization from the artery of Davidoff and Schechter for falx dural arteriovenous fistulae. A 74-year-old-man was incidentally diagnosed with falx dural arteriovenous fistulae during head magnetic resonance imaging. Results revealed dilatation of the cortical veins in the right occipital lobe. Angiographically, falx dural arteriovenous fistula was observed to be fed by the right middle meningeal artery, right occipital artery, right posterior meningeal artery, and the artery of Davidoff and Schechter (Borden type III). However, due to the tortuosity, the first transarterial embolization surgery through the middle meningeal artery, occipital artery, and posterior meningeal artery was unsuccessful. Therefore, the second transarterial embolization was performed through the artery of Davidoff and Schechter. Arteriovenous fistulae disappeared after administering Onyx injections through the artery of Davidoff and Schechter. Based on our findings, the artery of Davidoff and Schechter can be an approach route to treat dural arteriovenous fistulae. Moreover, the most important point of transarterial embolization procedures through the artery of Davidoff and Schechter is to navigate the microcatheter along the falx.
RESUMO
A 10-year-old girl was transferred to our hospital with left hemiparesis. Diffusion-weighted magnetic resonance imaging (MRI) of the brain showed a signal lesion in the right posterior limb of the internal capsule and magnetic resonance angiography showed poor visualization of the right internal carotid artery (ICA), and a defect area was present in a part of the supraclinoid portion of the right ICA. Based on the clinical and radiological findings, the patient was diagnosed with ischemic stroke due to right ICA dissection (ICAD). She received 5 days of intravenous argatroban followed by oral aspirin. A month later, her hemiparesis markedly improved. As early diagnosis of ICAD is crucial for prompt treatment in children with unexplained gross neurologic abnormalities, this disease should be suspected and MRI should be performed even without a history of blunt trauma to the head and neck.
RESUMO
Incidental gallbladder carcinoma (IGC), defined as unexpected malignancy identified in the surgical gallbladder specimen of a cholecystectomy performed for a benign diagnosis, can be difficult to suspect preoperatively. Furthermore, there are valid clinical reasons to defer reoperation for additional resection, particularly in elderly patients. The present study aimed to determine the long-term outcomes and prognostic factors associated with recurrence in patients with IGC. The medical records of 678 patients who underwent cholecystectomy at Toyooka Hospital between September 2011 and November 2017 were reviewed. The cases identified to be IGC were retrospectively analyzed to determine patient and histopathological characteristics, surgical details, long-term outcomes and factors associated with cancer recurrence. A total of 22 patients were diagnosed with gallbladder carcinoma following cholecystectomy by histopathological examination, and 12 of these were identified to be IGC. The median age was 80 years (range 70-89 years). Although 6 of the 12 patients with IGC had stage pT2 or pT3 tumors, only 1 patient underwent additional resection. Recurrence occurred in 3 of the 8 patients who did not undergo additional resection and were available for long-term follow-up. Recurrence was not associated with the extent of tumor invasion but may be associated with other histopathological findings, preoperative treatment history and risk factors for recurrence. Furthermore, long-term survival was observed in patients with pT2 and pT3 tumors who did not undergo additional resection. Recurrence was not associated with the extent of tumor invasion but may be associated with other histopathological findings, preoperative treatment history, and risk factors for recurrence. Furthermore, long-term survival was observed in patients with pT2 and pT3 tumors who did not undergo additional resection. Even if it is a progressive IGC case, appropriate preoperative treatment or cholecystectomy without persistence of the carcinoma cell, based on a preoperative image evaluation and a postoperative histopathological examination, may greatly influence the long-term prognosis of IGC.
RESUMO
AIMS: Although frameshift variants in the microsatellite area of shugoshin 1 (SGO1) have been reported in the context of microsatellite instability-high (MSI-H)/deficient mismatch repair gastrointestinal cancer, most have been evaluated only in early stage I-III patients, and only two of its five microsatellite regions have been evaluated. Therefore, we investigated the frequency and MSI status of microsatellite frameshift variants in gastric cancer cases, including stage IV. METHODS: In a total of 55 cases, 30 gastric cancer resection and 25 non-resection cases, DNA was extracted from both tumour and normal parts and PCR was performed. The variant was confirmed by TA cloning, and MSI was evaluated using GeneMapper software. RESULTS: A frameshift variant of c.973delA was observed in 16 of the 45 evaluable cases. Its frequency was 35.6%. Of the 25 cases that could be assessed for MSI status, two cases of MSI-H were associated with the c.973delA SGO1 variant. However, c.973delA SGO1 variant was also observed in four cases of microsatellite stable. CONCLUSION: Our study shows that SGO1 frameshift variants are not always associated with MSI status.
RESUMO
Decreased trough level of infliximab (TLI) is associated with diminished efficacy in patients with Crohn disease (CD). We examined whether TLI at 14 weeks subsequent to the start of infliximab (IFX) treatment would impact long-term clinical course.Serum IFX levels and antibodies to IFX (ATI) at 14 and 54 weeks after IFX administration were measured in 12 patients with mild to moderate CD. We examined patient background, clinical severity, blood test values, and the relationship between ATI and TLI up to 108 weeks.We compared the group with TLIâ<â3âµg/mL at 14 weeks (TLI(14)â<â3 group) the group with TLIâ>â3âµg/mL (TLI(14) ≥ 3 group). Patients in the TLI(14) ≥ 3 group were significantly more likely to use immunomodulators before IFX treatment induction (Pâ=â.01). At 54 weeks, 2 cases of ATI production were observed in the TLI(14)â<â3 group, but no ATI production was observed in the TLI(14) ≥ 3 group. TLI in the TLI(14) ≥ 3 group at 54 weeks was significantly higher than in the TLI(14)â<â3 group (6.5âµg/mL vs 1.0âµg/mL; Pâ<â.01). Although CD activity index and serum albumin values in the TLI(14) ≥ 3 group at 14, 54, and 108 weeks significantly improved compared to baseline, these improvements were not observed in the TLI(14)â<â3 group. The remission maintenance rate at 108 weeks evaluated with the Kaplan-Meier method was significantly higher in the TLI(14) ≥ 3 group than the TLI(14)â<â3 group (100% vs 33.3%; Pâ=â.02).The TLI 14 weeks after IFX treatment in patients with CD affects long-term outcome.

The frequency of deficient mismatch repair (dMMR) or microsatellite instability-high colorectal cancer (CRC) is estimated to be ~15% of all patients with CRC; however, the patients reported are limited to surgical cases, and the frequency of patients exhibiting stage 0 disease is not considered, despite the currently increasing use of endoscopic techniques to cure a number of these patients. In the present study, the DNA MMR status for stage 0 patients with CRC treated using endoscopic submucosal dissection or endoscopic mucosal resection was analyzed via immunohistochemical staining of four types of proteins, namely MutL homolog 1 (MLH1), MutS homolog 2 (MSH2), MSH6 and PMS1 homolog 2 MMR system component, in adenocarcinoma specimens. Notably, none of the endoscopically resected specimens exhibited dMMR among the 41 patients diagnosed with stage 0 CRC. Since tumors harboring dMMR progress more rapidly than tumors with chromosomal instability, the present results highlight the importance of tumor resection during very early phases that exist before the promoter region of MLH1 becomes hypermethylated, resulting in a loss of DNA MMR function.
RESUMO
Gastrointestinal stromal tumors (GISTs) arising at sites other than the alimentary tract are rare, and they are called extra-GISTs (EGISTs). We report a case of a large EGIST forming a cyst, probably arising in the mesentery of the transverse colon. A 64-year-old Japanese man presented to a hospital with an abdominal tumor forming a large cyst. Intraoperatively, the tumor was neither present in nor in contact with the alimentary tract. It was present in the mesentery of the transverse colon and was attached to the greater omentum and peritoneum, immediately anterior to the body of the pancreas. The tumor was resected with the spleen and a part of the pancreas. Histological examination of the tumor revealed that it belonged to the high-risk category of cystic EGISTs.
RESUMO
BACKGROUNDS: Trifluridine is an active antitumor component of TAS-102 that resembles 5-fluorouracil. Although patients with advanced colorectal cancer (CRC) exhibiting a mismatch repair (MMR) deficiency reportedly do not benefit from 5-fluorouracil-based chemotherapy and we previously reported that truncated methyl-CpG binding domain protein 4 (MBD4) enhances 5-fluorouracil cytotoxicity in MMR-deficient CRC cells, little is known regarding the effect of MMR deficiency on trifluridine cytotoxicity in CRC. AIM: We investigated whether trifluridine induces cytotoxicity in a DNA MMR-dependent manner and evaluated how truncated MBD4 alters trifluridine cytotoxicity. METHODS: We utilized the human CRC cell lines HCT116 (hMLH1-deficient cells) and HCT116+ch3 (hMLH1-restored cells) and compared their sensitivities to trifluridine. And we established 5-fluorouracil-refractory hMLH1-deficient cells and analyzed trifluridine cytotoxicity. Finally, we established truncated MBD4 overexpressed CRC cell lines, and compared trifluridine sensitivity.Results: The sensitivities of HCT116 and HCT116+ch3 to trifluridine were comparable. 5-Fluorouracil-refractory hMLH1-deficient cells treated with trifluridine showed an equal or greater sensitivity than non-5-fluorouracil-refractory cells. Moreover, MBD4tru cells were more sensitive than the control cells to trifluridine.Conclusions: Trifluridine induces cytotoxicity independently of the DNA MMR status as well as under 5-fluorouracil-refractory conditions, and the MBD4 frameshift mutation enhances trifluridine cytotoxicity.
