RESUMO

AIM: There are well-known methods for decompressing the colorectal tract before surgery, including transanal decompression tubes (TDT) and self-expanding metallic stents (SEMS). This study aimed to compare the short and long-term results in patients with malignant large bowel obstruction in whom TDT or SEMS were placed before surgery. METHODS: This retrospective observational study enrolled 225 patients with malignant large bowel obstruction in whom TDT or SEMS were placed preoperatively and underwent R0 resection between 2008 and 2020. One-to-two propensity score matching was performed according to patient characteristics. Short- and long-term outcomes were compared. The primary endpoint was relapse-free survival (RFS). The secondary endpoints were the overall survival (OS) and postoperative complication rate. RESULTS: Fifty-seven patients in the TDT group and 114 in the SEMS group were matched. The 3-year RFS rates were 66.7% in the TDT group and 69.9% in the SEMS group (p = 0.54), and the 3-year OS rates were 90.5% in the TDT group and 87.1% in the SEMS group (p = 0.52). No significant differences in the long-term results were observed between the two groups. Regarding short-term results, the SEMS group had significantly fewer stoma construction (p = 0.007) and shorter postoperative hospitalization (p < 0.001). The incidence of postoperative complications (grade ≥ 2) was significantly lower in the SEMS group (p = 0.04). CONCLUSION: No significant differences in the long-term results were observed between the TDT and SEMS group. The SEMS showed significant usefulness in terms of improving short-term outcomes.

RESUMO

A 77-year-old man presented to our hospital with diarrhea and weight loss. Upper gastrointestinal endoscopy revealed advanced Type 3 gastric cancer measuring 40 mm in the lower greater curvature of the stomach. Biopsy from a gastric tumor revealed moderately differentiated tubular adenocarcinoma overexpressing HER2. Abdominal contrast-enhanced computed tomography(CT)showed multiple liver metastases in S3 and S5. We diagnosed HER2-positive gastric cancer with liver metastasis. Systemic chemotherapy was administrated, with a total of 13 courses of combination therapy with S-1, oxaliplatin and trastuzumab. After chemotherapy, the primary tumor was significantly reduced and liver metastases were almost undetectable. Laparoscopic distal gastrectomy and partial hepatectomy were performed as conversion surgery. The patient was discharged on the 9th day without any postoperative complications. Postoperative pathological findings showed no residual tumor in either gastric and hepatic specimens, and the therapeutic effect of chemotherapy was diagnosed as pathological complete response. We report a case of HER2-positive advanced gastric cancer with multiple liver metastases that achieved a pathologically complete response to chemotherapy followed by conversion surgery. Laparoscopic surgery would be one of an effective option for conversion surgery.

RESUMO

Laparoscopic and endoscopic cooperative surgery(LECS)for gastric gastrointestinal stromal tumor(GIST)has become a popular surgery with both curability and functional preservation. In this study, we examined the outcomes of 14 patients who underwent classical LECS or CLEAN-NET in our hospital. Until March 2022, classical LECS was performed in patients with intraluminal growth tumors or tumors close to the gastroesophageal junction. After April 2022, classical LECS was performed in patients with intraluminal growth tumors without ulceration, and CLEAN-NET was performed in patients with ulceration or intramural growth tumors. There were 10 males and 4 females with a median age of 80.5 years. Intraluminal growth tumor were 8 patients, close to the gastroesophageal junction tumor were 3, and intramural growth tumor were 4, respectively. Five of these patients had tumors with ulceration. Classical LECS was performed in 10 patients and CLEAN-NET in 4 patients, and the median operative time was 165.5 minutes. All patients underwent R0 resection, and no postoperative complications or recurrences were observed. LECS was performed safely, and it is important to select the surgical procedure according to the tumor site and growth type.

RESUMO

We report a case of a patient with locally recurrent esophageal cancer after chemoradiation therapy(CRT)who responded to nivolumab. The patient was an 86-year-old man with advanced esophageal cancer. Upper gastrointestinal endoscopy (EGD)revealed a type 2 lesion in the middle thoracic esophagus, and biopsy revealed squamous cell carcinoma(SCC). Contrast- enhanced CT showed invasion of the left main bronchi. The patient was diagnosed as Stage Ⅳa advanced esophageal cancer, and was treated with 5-FU plus cisplatin chemotherapy, and 60 Gy of radiation therapy. The tumor disappeared by CT and EGD, and the patient was followed up for observation. The patient experienced a feeling of tightness again, and EGD revealed an ulcerative lesion in the middle thoracic esophagus, and a biopsy detected SCC. Because of the early recurrence after CRT, the patient was judged to be resistant to 5-FU plus cisplatin chemotherapy, and 8 courses of nivolumab were administered as second-line treatment. Follow-up EGD confirmed disappearance of ulcerative lesions, and no tumors have been observed to date.

RESUMO

Novel small molecules were synthesized and evaluated as retinoic acid receptor-related orphan receptor-gamma t (RORγt) inverse agonists for the treatment of inflammatory and autoimmune diseases. A hit compound, 1, was discovered by high-throughput screening of our compound library. The structure-activity relationship (SAR) study of compound 1 showed that the introduction of a chlorine group at the 3-position of 4-cyanophenyl moiety increased the potency and a 3-methylpentane-1,5-diamide linker is favorable for the activity. The carbazole moiety of 1 was also optimized; a quinazolinedione derivative 18i suppressed the increase of IL-17A mRNA level in the lymph node of a rat model of experimental autoimmune encephalomyelitis (EAE) upon oral administration. These results indicate that the novel quinazolinedione derivatives have great potential as orally available small-molecule RORγt inverse agonists for the treatment of Th17-driven autoimmune diseases. A U-shaped bioactive conformation of this chemotype with RORγt protein was also observed.

RESUMO

A series of novel phenylglycinamides as retinoic acid receptor-related orphan receptor-gamma t (RORγt) inverse agonists were discovered through optimization of a high-throughput screen hit 1. (R)-N-(2-((3,5-Difluoro-4-(trimethylsilyl)phenyl) amino)-1-(4-methoxyphenyl)-2-oxoethyl)-3-hydroxy-N-methylisoxazole-5-carboxamide (22) was identified as one of the best of these compounds. It displayed higher subtype selectivity and specificity over other nuclear receptors and demonstrated in vivo potency to suppress the transcriptional activity of RORγt in a mouse PD (pharmacodynamic) model upon oral administration.

RESUMO

A series of tetrahydroisoquinoline derivatives were designed, synthesized, and evaluated for their potential as novel orally efficacious retinoic acid receptor-related orphan receptor-gamma t (RORγt) inverse agonists for the treatment of Th17-driven autoimmune diseases. We carried out cyclization of the phenylglycinamide core by structure-based drug design and successfully identified a tetrahydroisoquinoline carboxylic acid derivative 14 with good biochemical binding and cellular reporter activity. Interestingly, the combination of a carboxylic acid tether and a central fused bicyclic ring was crucial for optimizing PK properties, and the compound 14 showed significantly improved PK profile. Successive optimization of the carboxylate tether led to the discovery of compound 15 with increased inverse agonistic activity and an excellent PK profile. Oral treatment of mice with compound 15 robustly and dose-dependently inhibited IL-17A production in an IL23-induced gene expression assay.

RESUMO

BACKGROUND/AIMS: Retinoid-related orphan receptor gamma t (RORγt) is a master regulator of T helper 17 cells that plays a pivotal role in the production of inflammatory cytokines including interleukin (IL)-17. Therefore, RORγt has attracted much attention as a target receptor for the treatment of inflammatory diseases including rheumatoid arthritis, multiple sclerosis, inflammatory bowel diseases, and psoriasis. This study aims to characterize TAK-828F, a potent and selective RORγt inverse agonist. METHODS: The biochemical properties of TAK-828F were evaluated using Time-Resolved Fluorescence Resonance Energy Transfer (TR-FRET) binding assay, surface plasmon resonance (SPR) biosensor assay, cofactor recruitment assay, reporter assay, and IL-17 expression assay. RESULTS: TR-FRET binding assay and SPR biosensor assay revealed rapid, reversible, and high affinity binding of TAK-828F to RORγt. The cofactor recruitment assay showed that TAK-828F inhibited the recruitment of steroid receptor coactivator-1 to RORγt. Furthermore, TAK-828F inhibited the transcriptional activity of human and mouse RORγt with selectivity against human RORα and RORß. TAK-828F also suppressed IL-17 production in Jurkat cells, overexpressing human RORγt. CONCLUSION: These favorable properties will be of advantage in the evaluation of TAK-828F in clinical studies for inflammatory diseases. Furthermore, these findings demonstrate that TAK-828F could serve as a pharmacological tool for further studies of RORγt and inflammatory diseases.

RESUMO

BACKGROUND: Complete surgical resection is essential for a cure for most gastric cancer. Recently it was reported that surgical Apgar score (SAS) can predict postoperative complication and that postoperative complication is associated with poor long-term survival. The aim of this study is to assess whether SAS can predict overall survival (OS) after surgery for gastric cancer. METHODS: We retrospectively compared clinicopathological characteristics and survival between high and low SAS score groups in patients who underwent gastrectomy for gastric cancer. RESULTS: Low-scored SAS group (group L) was significantly more common among ASA-PS 2, open approach, total gastrectomy, D2 lymph node dissection, postoperative complication grade 2-4, deep tumor invasion, lymph node metastases, and advanced pathological TNM stage than high-scored SAS group (group H). The 5-year OS of group H and group L were 81.6 and 55.9 %, respectively (p < .001); OS of group L tended to be poorer than that of group H in stage III patients (p = .060) and in stage IV patients (p < .001). In multivariate analysis, pathological stage and SAS were identified as independent predictors for OS. CONCLUSIONS: SAS is useful for predicting survival after surgery for gastric cancer.

RESUMO

A 63-year-old man underwent low anterior resection for rectal cancer.A synchronous liver metastasis located in segment 8 was 12 cm in diameter and unresectable due to its proximity to the inferior vena cava(IVC).The postoperative pathological findings revealed a T3(SS), N0, M1(liver)Stage IV tumor, and wild type K-RAS was expressed.We chose FOLFIRI plus cetuximab(Cmab)for first-line chemotherapy.After 6 courses, we changed the molecular target drug from Cmab to bevacizumab( Bmab)because the liver metastasis remained unresectable.The patient had long-term stable disease(SD)for approximately 30 months with the FOLFIRI-based regimen.We then changed the regimen to mFOLFOX6 plus Bmab for second-line, Cmab for third-line, and trifluridine/tipiracil hydrochloride for fourth-line chemotherapy to treat progressive disease(PD).After treatment with these chemotherapies, the patient wished to continue treatment.We restarted FOLFIRI plus Bmab for fifth-line chemotherapy as his general condition was still good.Consequently, his tumor markers levels decreased with stabilization of the disease on CT scans, and he continued therapy for 6 months while maintaining a good quality of life.This case suggested that rechallenge with anti-cancer agents could be effective and improve the prognosis of colorectal cancer patients after using all key drugs.

RESUMO

A30 -year-old woman underwent total gastrectomy with D2 lymph node dissection after being diagnosed with clinical T3, N2, M0, Stage III B gastric cancer. The postoperative pathological findings revealed a T3(SE), N2, M0, Stage III B tumor. Headache, dizziness, and vomiting occurred during chemotherapy for peritoneal recurrence, using weekly paclitaxel on days 1, 8, and 15. Head CT showed a solitary tumor with a diameter of 28mm in the cerebellum, as well as cerebellar swelling and hydrocephalus. She underwent an emergency craniotomy and tumor enucleation. Pathological examination revealed a metastatic brain tumor from the gastric cancer. She received 12 courses of CPT-11 plus cisplatin until discontinuation because of an adverse event. The patient is alive 6 years after the diagnosis of the cerebellar metastasis without recurrence.

RESUMO

BACKGROUND: Because obesity is a risk factor during surgery, the effects of a preoperative exercise program to reduce the incidence of peri- and postoperative complications in patients with a high body mass index (>25 kg/m(2)) and metabolic syndrome were investigated. An assessment of the effects of prospectively planned preoperative exercise was performed in a prospective matching study comparing an exercise testing group and a usual preoperative preparation group who underwent gastrectomy for gastric cancer in Japan. METHODS: Stage I gastric cancer patients with metabolic syndrome diagnosed according to the criteria of the Japanese Ministry of Health, Labor, and Welfare underwent surgery after preoperative exercise. The control group was selected from a database using an individual matching approach for surgery, sex, weight, body mass index, volume of visceral fat, and institution. The primary end point was the frequency of postoperative complications such as cardiovascular events, pneumonia, and surgery-related abdominal complications. RESULTS: Data from a total of 72 patients (54 in the surgery-alone group, 18 in the preoperative exercise group) were analyzed. The median operative time and amount of bleeding were 208 min and 130 ml in the surgery-alone group and 248 min and 105 ml in the exercise group, respectively. Postoperative complications occurred in one case (5.5 %) in the exercise group and 22 (40.7 %) cases in the surgery-alone group. CONCLUSIONS: Preoperative exercise is safe, and its benefits in reducing postoperative complications are promising and therefore warrant further investigation.

RESUMO

BACKGROUND: This randomized Phase III trial will evaluate whether the methylene blue-assisted technique is efficient for harvesting lymph nodes after radical surgery for gastric cancer. METHODS/DESIGN: Patients that undergo distal or total gastrectomy with radical nodal dissection will be randomly assigned to Group A: the standard group, the lymph nodes (LNs) will be harvested from the fresh specimen immediately after surgery, or Group B: the methylene blue-assisted group, where the LNs will be harvested from specimens fixed with 10% buffered formalin with methylene blue for 48 hours after surgery. The primary endpoint is the ratio of the number of the harvested LNs per time (minute). The secondary endpoint is the number of harvested LNs. A 25% reduction in the ratio of harvested lymph-node/time (minute) was determined to be necessary for this test treatment, considering the balance between the cost and benefit. Retrospective data was used to estimate the ratio of the number of the harvested LNs per time (minute) to be 40/30 minutes in Group A. A 25% risk reduction and a rate of 40/22.5 minutes is expected in Group B. Therefore, the sample size required ensuring a two-sided alpha error of 5% and statistical power of 80% is 52 patients, with 26 patients per arm. The number of patients to be accrued was set at 60 in total, due to the likelihood of enrolling ineligible patients. TRIAL REGISTRATION: UMIN000008624.

RESUMO

INTRODUCTION: A number of studies have evaluated the effects of subcutaneous drainage during digestive surgery. All of the previous studies assessed the usefulness of active-suctioning drain, including two randomized controlled studies which found no benefit for the placement of active-suctioning drains in digestive surgery. The utility of passive drainage has not been evaluated previously. The purpose of this study was to evaluate the efficacy of subcutaneous passive drainage system for preventing surgical site infections during major colorectal surgery. PATIENTS AND METHODS: A total of 263 patients who underwent major colorectal surgery were enrolled in this study. Patients were randomly assigned to receive subcutaneous passive drainage or no drainage. The primary outcome measured was the incidence of superficial surgical site infections. The secondary outcomes measured were the development of hematomas, seromas, and wound dehiscence. RESULTS: Finally, a total of 246 patients (124 underwent passive drainage, and 122 underwent no drainage) were included in the analysis after randomization. There was a significant difference in the incidence of superficial surgical site infections between patients assigned to the passive drainage and no drainage groups (3.2 % vs 9.8 %, respectively, P = 0.041). There were no cases that developed a hematoma, seroma, or wound dehiscence in either group. A subgroup analysis revealed that male gender, age ≥75 years, diabetes mellitus, American Society of Anesthesiologists (ASA) status ≥2, blood loss ≥100 ml, and open access were factors that were associated with a beneficial effect of subcutaneous passive drainage. CONCLUSIONS: Subcutaneous passive drainage provides benefits over no drainage in patients undergoing major colorectal surgery.

RESUMO

BACKGROUND: Enhanced recovery after surgery (ERAS) programs have been reported to be feasible and useful for maintaining physiological function and facilitating recovery after colorectal surgery. The feasibility of such programs in gastric surgery remains unclear. This study assessed whether an ERAS program is feasible in patients who undergo gastric surgery. METHODS: The subjects were patients who underwent gastric surgery between June 2009 and February 2011 at the Department of Gastrointestinal Surgery, Kanagawa Cancer Center. They received perioperative care according to an ERAS program. All data were retrieved retrospectively. The primary end point was the incidence of postoperative complications. The secondary end point was postoperative outcomes. RESULTS: A total of 203 patients were studied. According to the Clavien-Dindo classification, the incidence of ≥ grade 2 postoperative complications was 10.8% and that of ≥ grade 3 complications was 3.9%. Nearly all patients did not require delay of meal step-up (95.1%). Only 6 patients (3.0%) underwent reoperation. The median postoperative hospital stay was 9 days. Only 4 patients (2.0%) required readmission. There was no mortality. CONCLUSIONS: Our results suggest that our ERAS program is feasible in patients who undergo gastric surgery.

RESUMO

We report a case of an intractable fistula repaired by transsacral direct suture. A 65-year-old man underwent low anterior resection for rectal cancer. He subsequently underwent ileostomy due to anastomosis leakage. The fistula of the anastomosis persisted 3 months after surgery. He underwent surgery to repair the fistula using a transsacral approach. After removing the coccyx, the fistula in the postrectal space was exposed directly. The presence of the fistula was confirmed by an air leak test and was closed by direct suture. After 33 days, the patient underwent ileostomy closure.

RESUMO

External supravesical hernias with ovarian incarceration have not been reported previously. Here, we describe transabdominal preperitoneal (TAPP) repair of an external supravesical hernia with ovarian incarceration. A 68-year-old woman presented to our outpatient clinic with the chief complaint of right inguinal swelling and pain. A 3-cm-diameter mass in the right inguinal region that was difficult to reduce was palpable, and computed tomography (CT) revealed a suspicious lesion of the right hydrocele of the canal of Nuck. Hydrocelectomy was performed through an inguinal incision, and the external inguinal ring was repaired using the Marcy method. The histopathological examination confirmed the diagnosis of the canal of Nuck. Three months postoperatively, the patient again presented with right inguinal pain, and CT revealed a right femoral hernia requiring surgical repair. Intraoperative findings revealed a right external supravesical hernia with an incarcerated ovary, which was laparoscopically reduced and repaired with a mesh. At the three-month follow-up, there were no postoperative complications or recurrences. Incarcerated ovaries with inguinal hernias have been reported in girls; however, incarcerated ovaries with external supravesical hernias have not been reported in women. Although the preoperative diagnosis was difficult to make in this case, the laparoscopic approach led to the diagnosis and successful mesh repair. Although optimal mesh repair of external supravesical hernias using TAPP has not been established, we believe that 2-5 cm around the hernial orifice, the Hesselbach triangle, and the lateral triangle should be covered with mesh.

RESUMO

BACKGROUND: Multidetector-row CT (MDCT) may provide accurate preoperative staging of resectable gastric cancer. However, the standard methods and criteria to diagnose the T and N stages to select the patients who are good candidates for neoadjuvant chemotherapy have not been established yet. METHODS: The aim of this prospective study was to evaluate the accuracy of MDCT to diagnose the serosal invasion and nodal metastases of gastric cancer. Patients who had gastric adenocarcinoma underwent MDCT scanning using a standardized method. The T and N stage were diagnosed by prespecified criteria. The analyses were performed in the patients who had cN0-2 and M0 tumors and underwent curative gastrectomy as a primary treatment. The accuracy was calculated by comparing the results of MDCT with the histopathological findings. RESULTS: A total of 315 patients were analyzed. The overall diagnostic accuracy (95 % confidence interval) of T staging was 71.4 % (225 of 315, 66.2-76.1). The accuracy, sensitivity, and specificity for serosal invasion were 85.7 % (81.4-89.1), 54.5 % (42.6-66.0), and 94.0 % (90.3-96.3), respectively. The false-positive rate for serosal invasion was 6.0 % (2.9-7.7). The overall diagnostic accuracy of N staging was 75.9 % (239 of 315, 70.9-80.3). The accuracy, sensitivity, and specificity for nodal metastases were 81.3 % (76.6-85.2), 46.4 % (36.8-56.3), and 96.8 % (93.5-98.4), respectively. The false-positive rate for nodal metastases was 3.2 % (1.6-6.5 %). CONCLUSIONS: These results suggest that MDCT provides an accurate diagnosis with high specificity and a low false-positive rate and can be used to select the patients who are candidates for preoperative chemotherapy.

RESUMO

BACKGROUND: Compliance of S-1 adjuvant chemotherapy is not high. The aim of the present study is to clarify risk factors for continuation of S-1 after gastrectomy. METHODS: This retrospective study selected patients who underwent curative D2 surgery for gastric cancer, were diagnosed with stage 2/3 disease, creatinine clearance more than 60 ml/min, and received adjuvant S-1 at our institution between June of 2002 and December of 2011. Time to S-1 treatment failure (TTF) was calculated. RESULTS: A total of 103 patients were selected for the present study. When TTF curve stratified by each clinical factor was compared by the log-rank test, body weight loss (BWL) of 15 % was regarded as a critical point. Both univariate and multivariate Cox proportional hazard analyses demonstrated that BWL was the significant independent risk factor. Moreover, BWL remained a significant factor in both the univariate and multivariate analyses in the subset excluding 8 patients who discontinued S-1 because of recurrence. The 6-month continuation rate was 66.4 % in the patients with BWL < 15 and 36.4 % in patients with BWL ≥ 15 % (P = .017). CONCLUSIONS: BWL was the most important risk factor for the compliance of adjuvant chemotherapy with S-1 in the patients with stage 2/3 gastric cancer who underwent D2 gastrectomy. To improve drug compliance that leads to survival, it is a key to maintain body weight before starting S-1 adjuvant. Our study emphasizes the requirement for adequate studies of perioperative nutritional intervention in patients who receive gastrectomy for advanced gastric cancer.

RESUMO

Laparoscopic esophagojejunostomy using a circular stapler is associated with technical difficulties in the purse-string sutures used to insert the anvil head and in obtaining an adequate visual field to prevent rolling the mesentery and the wall of the jejunum on the mesenteric side into the anastomosis. To overcome these difficulties, we used the EndoStitch to create the purse-string suture and the ENDOCAMELEON to create the visual field to stretch the jejunum. After resecting the esophagus, purse-string sutures were placed using the EndoStitch. A total of five to six needle deliveries were performed. Next, the anvil head was inserted into the esophagus. The main unit of the EEA was inserted from the end of the resected jejunum. Then, the scope was changed to the ENDOCAMELEON. The main unit was slowly moved toward the anvil head. After making sure that the mesentery and the wall of the jejunum on the mesenteric side were not rolled into the anastomosis under the visual field created by the ENDOCAMELEON, the main unit was then fired. Thereafter, esophagojejunostomy was successfully completed. This technique was applied in 20 patients between April 2010 and May 2012. Laparoscopic esophagojejunostomy after total gastrectomy for gastric cancer was completed in all 20 patients. No case required conversion to open surgery. Neither anastomotic leakage nor stenosis was observed. This method is simple and useful for laparoscopic esophagojejunostomy after total gastrectomy for gastric cancer.
