RESUMO
BACKGROUND: Esophageal squamous cell carcinoma is characterized by field cancerization, wherein multiple cancers occur in the esophagus, head and neck, and stomach. Synchronous esophageal and colorectal cancers are also encountered with a certain frequency. A good prognosis can be expected if the tumors in both locations can be safely and completely removed. For patients with multiple cancers that occur simultaneously with esophageal cancer, it is necessary to perform a staged operation, taking into consideration the associated surgical invasiveness. It is also necessary to select multidisciplinary treatment depending on the degree of progression of the multiple lesions. We report our rare experience with a staged operation for a patient with synchronous advanced cancers of the esophagus and cecum who had previously undergone total gastrectomy with reconstruction by jejunal interposition for gastric cancer. CASE PRESENTATION: A 71-year-old man with a history of reconstruction by jejunal interposition after total gastrectomy was diagnosed as having multiple synchronous esophageal and cecal cancers. After neoadjuvant chemotherapy, we performed a planned two-stage operation, with esophagectomy and jejunostomy in the first stage and ileocecal resection and jejunal reconstruction with vascular anastomosis in the second. Postoperatively, the patient was relieved without major complications, and both tumors were amenable to curative pathologic resection. CONCLUSIONS: Our procedure reported here may be recommended as an option for staged resection and reconstruction in patients with simultaneous advanced esophageal and cecal cancer after total gastrectomy.

PURPOSE: Robot-assisted surgery has a multi-joint function, which improves manipulation of the deep pelvic region and contributes significantly to perioperative safety. However, the superiority of robot-assisted surgery to laparoscopic surgery remains controversial. This study compared the short-term outcomes of laparoscopic and robot-assisted surgery for rectal tumors. METHODS: This single-center, retrospective study included 273 patients with rectal tumors who underwent surgery with anastomosis between 2017 and 2021. In total, 169 patients underwent laparoscopic surgery (Lap group), and 104 underwent robot-assisted surgery (Robot group). Postoperative complications were compared via propensity score matching based on inverse probability of treatment weighting (IPTW). RESULTS: The postoperative complication rates based on the Clavien-Dindo classification (Lap vs. Robot group) were as follows: grade ≥ II, 29.0% vs. 19.2%; grade ≥ III, 10.7% vs. 5.8%; anastomotic leakage (AL), 6.5% vs. 4.8%; and urinary dysfunction (UD), 12.1% vs. 3.8%. After adjusting for the IPTW method, although AL rates did not differ significantly between groups, postoperative complications of both grade ≥ II (odds ratio [OR] 0.66, 95% confidence interval [CI] 0.50-0.87, p < 0.01) and grade ≥ III (OR 0.29, 95% CI 0.16-0.53, p < 0.01) were significantly less frequent in the Robot group than in the Lap group. Furthermore, urinary dysfunction also tended to be less frequent in the Robot group than in the Lap group (OR 0.62, 95% CI 0.38-1.00; p = 0.05). CONCLUSION: Robot-assisted surgery for rectal tumors provides better short-term outcomes than laparoscopic surgery, supporting its use as a safer approach.

BACKGROUND: Failure to rescue (FTR), defined as a postoperative complication leading to death, is a recently described outcome metric used to evaluate treatment quality. However, the predictive factors for FTR, particularly following highly advanced hepatobiliary-pancreatic surgery (HBPS), have not been adequately investigated. This study aimed to identify perioperative predictive factors for FTR following highly advanced HBPS. METHODS: This single-institution retrospective study involved 177 patients at Gifu University Hospital, Japan, who developed severe postoperative complications (Clavien-Dindo classification grades ≥ III) between 2010 and 2022 following highly advanced HBPS. Univariate analysis was used to identify pre-, intra-, and postoperative risks of FTR. RESULTS: Nine postoperative mortalities occurred during the study period (overall mortality rate, 1.3% [9/686]; FTR rate, 5.1% [9/177]). Univariate analysis indicated that comorbid liver disease, intraoperative blood loss, intraoperative blood transfusion, postoperative liver failure, postoperative respiratory failure, and postoperative bleeding significantly correlated with FTR. CONCLUSIONS: FTR was found to be associated with perioperative factors. Well-coordinated surgical procedures to avoid intra- and postoperative bleeding and unnecessary blood transfusions, as well as postoperative team management with attention to the occurrence of organ failure, may decrease FTR rates.

BACKGROUND: Postoperative pancreatic fistula (POPF) is a major complication of pancreatic surgery. Drain fluid amylase concentration (DAC) is considered a predictive indicator of POPF. However, other indicators related to postoperative drain fluid amylase status exist, and the most reliable indicator for predicting POPF remains unclear. The object of this study is to identify the single most accurate indicator related to drain fluid amylase status of POPF after distal pancreatectomy (DP). METHODS: This single-institution retrospective study included 122 patients who underwent DP. The study was conducted between 2010 and 2022 at Gifu University Hospital. We statistically analyzed DAC, drain fluid amylase amount (DAA) calculated by multiplying DAC and daily drainage volume, and drain and serum amylase concentration ratio (DSACR) to assess the correlation with POPF. RESULTS: Based on the definition and grading of the International Study Group of Pancreatic Fistula, 24.6 (%) of the 122 patients had Grades B and C POPF. The result of the receiver operating characteristic (ROC) curve for predicting POPF after DP, DSACR had the highest area under curve(AUC) value among DAC, DAA, and DSACR both POD1 and POD3. The cutoff value of DSACR on POD1 was 17 (AUC 0.69, sensitivity 80.0%, specificity 58.2%, and accuracy 63.6%). The cutoff value of DSACR on POD3 was 22 (AUC 0.77, sensitivity 77.7%, specificity 73.3%, and accuracy 73.6%). Overall, DSACR on POD3 had the highest AUC value. Furthermore, a multivariate logistic regression analysis revealed that pancreatic texture (soft; odds ratio [OR] 9.22; 95% confidence interval [CI] 2.22-44.19; p < 0.01) and DSACR on POD3 (> 22; OR 8.76; 95% CI 2.78-31.59; p < 0.001) were independently associated with POPF after DP. CONCLUSIONS: DSACR is the most reliable indicator of drain fluid amylase status for predicting POPF after DP.

BACKGROUND: The most common postoperative complication in malignant rectal surgery is anastomotic leakage (AL). AL after anterior or low anterior resection in rectal tumors is a fatal postoperative complication. Recently, the first automated suture circular stapler, which is expected to reduce the incidence of AL, (J&J). MATERIALS AND METHODS: This study included a total of 248 rectal tumor patients who underwent double stapler technique (DST) anastomotic procedures in the department of gastroenterological surgery /pediatric surgery at Gifu University School of Medicine from January 2017 to December 2021. The experience of a single institution utilizing the The Echelon circular™ stapler (ECP stapler:Manual VS Automatic) in rectal surgery cases was evaluated retrospectively from maintained database. RESULT: One hundred thirty-nine patients (58.4%) were performed by manual circular stapling, 99 patients (41.6%) by powerd circular stapling. Diverting stoma was performed in 45 cases (32.4%) by manual circular stapling, 42 patients (42.4%) by powerd circular stapling Postoperative complications were occurred clavien-dindo grade II or higher in 57 cases (23.9%) and grade III or higher in 20 cases (8.4%). Anastomotic leakage occurred in 14 patients (5.9%) within all grades. After IPTW, the variables of patient characteristics was SMD ≤ 0.2 (Table.3), and there was a significant difference in anastomotic leakage (Odds Ratio (OR), 0.57; 95% Confidence Interval(CI), 0.34-0.98; p = 0.041). In addition, there was no significant difference in postoperative complications in grade II or higher (OR, 0.88; 95%CI, 0.65-1.19; p = 0.417) and grade III or higher (OR, 0.46; 95%CI, 0.29-0.74; p = 0.001) were significantly remarkable lower in powered circular stapling group. CONCLUSION: In this IPTW comparison of patients undergoing rectal reconstructions, the ECP trial cohort had lower risks of several surgical complications AL and statistically signifcant lower rates of ileus/bowel obstruction, infection, and bleeding as Clavien-Dindo ≥ grade II and III as compared with for whom manual circular staplers were used.

BACKGROUND: Postoperative pancreatic fistula (POPF) is one of the serious complications of pancreatic surgery. When POPF occurs and becomes severe, it causes secondary complications and a longer treatment period. We previously reported a correlation between pancreatic fibrosis and magnetic resonance imaging (MRI) findings, and MRI may have the potential to predict POPF. This study aimed to assess the predictive ability of the pancreas-to-muscle signal intensity ratio on T1-weighted MRI (SIR on T1-w MRI) for POPF after distal pancreatectomy (DP). METHODS: This single-institution retrospective study comprised 117 patients who underwent DP. It was conducted between 2010 and 2021 at the Gifu University Hospital. We statistically analyzed pre-, intra-, and postoperative factors to assess the correlation with POPF. RESULTS: According to the definition and grading of the International Study Group of Pancreatic Fistula (ISGPF), 29 (24.8%) of the 117 patients had POPF grades B and C. In the univariate analysis, POPF was significantly associated with the pancreas-to-muscle SIR on T1-w MRI, the drainage fluid amylase concentration (D-Amy) levels on postoperative day (POD) 1 and 3, white blood cell count on POD 1 and 3, C-reactive protein level on POD 3, and heart rate on POD 3. In multivariate analysis, only the pancreas-to-muscle SIR on T1-w MRI (>1.37; odds ratio [OR] 23.25; 95% confidence interval [CI] 3.93-454.03; p < 0.01) and D-Amy level on POD 3 (>737 U/l; OR 3.91; 95% CI 1.02-16.36; p = 0.046) were identified as independent predictive factors. CONCLUSIONS: The pancreas-to-muscle SIR on T1-w MRI and postoperative D-Amy levels were able to predict the development of POPF after DP. The pancreas-to-muscle SIR on T1-w MRI may be a potential objective biomarker reflecting pancreatic status.

BACKGROUND: Even if 3D angiographic images of preoperative contrast-enhanced computed tomography (CT) are created, the coronal and axial sections can be unclear, and thus, it is difficult to achieve projection awareness similar to that of actual laparoscopic images. In recent years, the technology of analyzing and applying medical images has advanced, and surgical simulation and navigation have been widely used to improve the safety of surgical operations. It is important to understand pelvic anatomy in the area of rectal cancer, and use of the SYNAPSE VINCENT makes it possible to simulate the anatomy before surgery, which is very useful in educating surgeons and their assistants. MATERIALS AND METHODS: An important objective in surgery is to understand the anatomy of the external/internal iliac arteries and lymph nodes in lateral lymph node dissection (LLD) for rectal cancer. In this study, we explored the accuracy and usefulness of SYNAPSE VINCENT images of pelvic anatomy (especially vascular anatomy) analyzed preoperatively in two cases of LLD for rectal cancer in our department. RESULTS: The patients were two men aged 73 and 57 years, respectively. Both patients underwent robotic abdominal perineal resection and LLD with neoadjuvant chemoradiotherapy. The operating times for LLD were 138 and 106 min, estimated blood loss was less than 10 mL and 20 mL, and the harvested lymph nodes were nos. 21 and 22, respectively. The SYNAPSE VINCENT could be used for simulation and navigation before and during surgery. For experienced surgeons, the system helped them carry out operations more accurately. CONCLUSION: In the future, surgical support using virtual reality, augmented reality, and mixed reality based on medical images will be useful and is expected to improve the safety, accuracy, and efficiency of surgery, which is extremely useful for both young and skilled surgeons preparing for difficult operations.

A 77-year-old-woman underwent distal gastrectomy D2 lymph node dissection and cholecystectomy followed by Roux- en-Y reconstruction for Stage â ¢C gastric neuroendocrine cell carcinoma in January 2017. In July of the same year, an abdominal computed tomography scan revealed liver metastasis in segment 4. For treatment of recurrence, SP therapy(S-1 and cisplatin), ramucirumab plus weekly paclitaxel therapy, and nivolumab were administered in that order. TAS-102 was started as the fourth-line agent for multiple liver metastases, para-aortic lymph node metastases, and cancerous peritonitis. Although Grade 2 anemia, Grade 1 oral mucositis and general fatigue were observed during the treatment, both liver metastases and para-aortic lymph node metastases showed improvement after three courses, and the patient was able to continue 11 courses in 1 year. She died 1 year and 5 months after the first administration of TAS-102. TAS-102 can be effective after immune checkpoint inhibitor as a late treatment for gastric cancer and NEC. The appropriate timing for switching drug therapy may be important in the future. We report a favorable therapeutic effect of TAS-102 after immune checkpoint inhibitor treatment along with a review of the literature.

Cancer-related microRNAs (miRNAs) are emerging as promising and noninvasive biomarkers for colorectal cancer (CRC). This study aimed to investigate the usefulness of postoperative changes in plasma miR21-5p levels for recurrence and progressive disease (PD) after surgical resection. This study was a prospective study of 103 CRC patients who underwent surgical resection. Self-paired plasma samples collected pre-operation (Pre), 7 days post-operation (POD7), 1 month post-operation (POM1), and 6 months post-operation (POM6) were analyzed. The miRNA levels were evaluated by quantitative reverse transcription PCR. Among the enrolled patients, ten cases (9.7%) of postoperative recurrence and six cases (5.8%) of postoperative PD occurred at POM6. In the recurrence and PD group, plasma miR21-5p levels significantly increased (POM1: P < .01, POM6: P < .01, respectively). The area under the curve (AUC) value for postoperative changes in plasma miR21-5p levels at POM1 and POM6 to discriminate recurrence and PD were 0.675 and 0.715, respectively. Combined analysis with postoperative carcinoembryonic antigen (CEA) level in discriminating recurrence and PD increased AUC values (POM1: 0.715 and POM6: 0.789). Furthermore, multivariate analysis for recurrence and PD after surgical resection showed that postoperative changes in the plasma miR21-5p level at POM1 and POM6 were independent prognostic factors (POM1: P = .03, POM6: P < .01). The postoperative changes in plasma miR21-5p level could be a useful noninvasive biomarker for monitoring and predicting recurrence and PD after surgical resection of CRC patients. Furthermore, plasma miR21-5p can predict recurrence and PD after surgical resection.

BACKGROUND: The rate of pulmonary metastasectomy from colorectal cancer (CRC) has increased with recent advances in chemotherapy, diagnostic techniques, and surgical procedures. The purpose of this study was to investigate the prognostic factors for response to pulmonary metastasectomy and the efficacy of repeat pulmonary metastasectomy. METHODS: This study was a retrospective, single-institution study of 126 CRC patients who underwent pulmonary metastasectomy between 2000 and 2019 at the Gifu University Hospital. RESULTS: The 3- and 5-year survival rates were 84.9% and 60.8%, respectively. Among the 126 patients, 26 (20.6%) underwent a second pulmonary metastasectomy for pulmonary recurrence after initial pulmonary metastasectomy. Univariate analysis of survival identified seven significant factors: (1) gender (p = 0.04), (2) past history of extra-thoracic metastasis (p = 0.04), (3) maximum tumor size (p = 0.002), (4) mediastinal lymph node metastasis (p = 0.02), (5) preoperative carcinoembryonic antigen (CEA) level (p = 0.01), (6) preoperative carbohydrate antigen 19-9 (CA19-9) level (p = 0.03), and (7) repeat pulmonary metastasectomy for pulmonary recurrence (p < 0.001). On multivariate analysis, only mediastinal lymph node metastasis (p = 0.02, risk ratio 8.206, 95% confidence interval (CI) 1.566-34.962) and repeat pulmonary metastasectomy for pulmonary recurrence (p < 0.001, risk ratio 0.054, 95% CI 0.010-0.202) were significant. Furthermore, in the evaluation of surgical outcomes, the safety of second pulmonary metastasectomy was almost the same as that of initial pulmonary metastasectomy. CONCLUSIONS: Repeat pulmonary metastasectomy is likely to be safe and effective for recurrent cases that meet the surgical criteria. However, mediastinal lymph node metastasis was a significant independent prognostic factor for worse overall survival.

Case 1, a man in his 70s, was admitted because of a bleeding gastric ulcer during DCF therapy for esophageal cancer(EC). Three days after endoscopic hemostasis, abdominal pain and vomiting occurred.CT revealed hepatic portal venous gas (HPVG).No intestinal necrosis was observed on contrast-enhanced CT.Therefore, we selected a conservative treatment and found improvement.Case 2, a man in his 70s, developed frequent diarrhea during DCF therapy for EC.Case 3, a man in his 80s, developed hematochezie during DCF therapy for EC.Both cases 2 and 3 were diagnosed as HPVG using abdominal ultrasonography.The symptoms were mild, so we selected a conservative treatment and found improvement.Case 4, a man in his 60s, noticed sudden severe abdominal pain during DGS therapy for EC.Plain CT detected HPVG and gas in the small intestinal wall.We suspected intestinal necrosis due to HPVG with peritoneal irritation and performed emergency small intestine resection.We encountered 4 patients who developed HPVG during chemotherapy.The presence of HPVG is a poor prognostic sign, suggestive of intestinal necrosis, but some patients show improvement with conservative treatments.We also discuss previous reviews and reports.

BACKGROUND: In recent years, laparoscopic surgery has been widely used for rectal cancer. In laparoscopic rectal surgery, a double-stapling technique (DST) anastomosis using a stapling device is considered a relatively difficult procedure. Postoperative anastomotic leakage (AL) is a major complication related to patients' quality of life and prognosis. METHODS: This study was a retrospective, single-institution study of 101 rectal cancer patients who underwent laparoscopic low anterior resection (LAR) with DST anastomosis (excluding simultaneous resection of other organs and construction of protective diverting stoma) between February 2008 and November 2017 at the Gifu University Graduate School of Medicine. This study aimed to identify risk and early predictive factors of AL. RESULTS: Among 101 patients, symptomatic AL occurred in 13 patients (12.9%), of whom 10 were male and 3 were female. Their median BMI was 22.7 kg/m2 (range, 17.9-26.4 kg/m2). Among the pre- and intraoperative factors, AL was significantly associated with tumor location (lower rectum), distance from the anal verge (< 6 cm), intraoperative blood loss (≥ 50 ml), and the number of linear staples (≥ 2) in univariate analysis. In multivariate analysis, only intraoperative blood loss (≥ 50 ml, odds ratio [OR] 4.59; 95% confidence interval [CI] 1.04-19.52; p = 0.045) was identified as an independent risk factor for AL. Among the postoperative factors, AL was significantly associated with tachycardia-POD1 (≥ 100 bpm), CRP-POD3 (≥ 15 mg/dl), fever on postoperative day (fever-POD) 3 (≥ 38 °C), and first defecation day after surgery (< POD3) in univariate analysis. In multivariate analysis, fever-POD3 (≥ 38 °C, OR 30.97; 95% CI 4.68-311.22; p = 0.0003) and first defecation day after surgery (< POD3, OR 5.82; 95% CI 1.34-31.30; p = 0.019) were identified as early predictive factors for AL. CONCLUSION: In this study, intraoperative blood loss was an indicator of difficulty in a transection and anastomosing procedure, and fever-POD3 and early first defecation day after surgery were independent early predictive factors for AL. Careful surgery using an appropriate technique and standardized procedures with minimal bleeding and careful postoperative management paying attention to fever and defecation may prevent the onset and severity of AL.

BACKGROUND: Carcinoma and adenoma of the duodenum, including the papilla of Vater, are problematic diseases in patients with familial adenomatous polyposis (FAP). CASE PRESENTATION: A 36-year-old man underwent a periodic medical examination for early colon cancer originating from FAP for which laparoscopic-assisted subtotal colectomy with a J-shaped ileal pouch-rectal anastomosis was performed 3 years earlier. A tumor was detected at the papilla of Vater along with elevation of total bilirubin and hepatobiliary enzymes. Although cytology did not determine the tumor to be an adenocarcinoma, we suspected adenocarcinoma due to its hypervascularity shown by contrast-enhanced computed tomography. Pylorus-preserving pancreaticoduodenectomy with modified Imanaga reconstruction and regional lymph node dissection (D2) was performed. The pathological study showed that the tumor was a papillary and moderately differentiated tubular adenocarcinoma. The patient is currently in good health without recurrence, weight loss, or severe diarrhea at 12 months after surgery. CONCLUSIONS: Awareness of biliary-pancreatic symptoms and periodic gastroduodenoscopy might contribute both to the early detection of duodenal or periampullary polyps and cancer and to the radical treatment of FAP. Modified Imanaga reconstruction has the potential to become one of the more effective procedures for providing good quality of life to FAP patients with duodenal or periampullary cancer.

INTRODUCTION: Dermadrome is a term coined by combining the words "dermatology" and "syndrome," and it refers to dermatological symptoms that reflect visceral lesions. PRESENTATION OF CASE: Herein, we present the case of an 83-year-old female patient who presented with generalized blistering and erythema during treatment for acute pancreatitis. She was referred to our dermatology department with worsening erythema, although the acute pancreatitis improved. The cause of the erythema was suspected to be drug-induced, infectious, or related to collagen disease; however, the exact cause was unknown. Computed tomography and endoscopic ultrasonography findings revealed a mixed-type intraductal papillary mucinous neoplasm (IPMN). Refractory erythema was suspected to have been caused by a dermadrome due to IPMN. Consequently, she was referred to our department. The main pancreatic duct was dilated along its entire length, and tumor extension was difficult to determine; therefore, a total pancreatectomy was performed. The postoperative course was uneventful, and erythema gradually improved. The histopathological evaluation indicated high-grade dysplasia of the IPMN. DISCUSSION: The patient's skin rash, which did not improve with treatment that included high-dose steroids, began to improve after surgery, and the disease was thought to be a dermadrome caused by IPMN. CONCLUSION: We believe that this is the first reported case of IPMN with a dermadrome that resolved after a total pancreatectomy.
RESUMO
Owing to advances in cancer treatment and the diversification of treatment methods, cancer-associated thrombosis is increasing. Cancer can cause blood clots by activating the blood clotting system, increasing clotting factors through inflammation, reducing blood flow due to immobilization and damaging blood vessels through treatments such as chemotherapy. In clinical practice, superior mesenteric vein (SMV) thrombosis is occasionally observed in patients with cancer; however, certain cases of asymptomatic thrombosis can be serious. In the present case, a 71-year-old woman underwent laparoscopic high anterior resection for colorectal cancer. The patient received capecitabine as postoperative adjuvant chemotherapy for 6 months. Contrast-enhanced CT after the completion of chemotherapy revealed a sizable thrombus in the SMV. The thrombus occupied the SMV lumen without evident intestinal ischemia. D-dimer levels were elevated. Since the patient remained asymptomatic, edoxaban (30 mg/day) was administered in an outpatient setting. Six months later, contrast-enhanced CT confirmed thrombus resolution. No hemorrhagic events were observed during edoxaban treatment. In conclusion, cancer and chemotherapy are risk factors for thrombosis, indicating that regular D-dimer measurements may be necessary during cancer treatment. In addition, edoxaban may be an effective therapeutic tool for SMV thrombosis during chemotherapy for cancer.
RESUMO
BACKGROUND/AIM: The Geriatric Nutritional Risk Index (GNRI) predicts prognosis in various cancers. This study examined the correlation between GNRI, complete adjuvant chemotherapy (AC), and prognosis in patients with resected pancreatic cancer. PATIENTS AND METHODS: We retrospectively evaluated 123 patients with pancreatic cancer who underwent pancreatectomies at our institute between January 2010 and December 2020. Kaplan-Meier and Cox regression methods were used to assess survival. Factors associated with complete AC were identified using logistic regression analysis. RESULTS: Among the 123 patients with pancreatic cancer, 93 (75.6%) initiated AC, and 55 (44.7%) completed AC. In multivariate analysis, the pre-operative GNRI was an independent prognostic factor for overall survival (OS) [hazard ratio=1.63, 95% confidence interval (CI)=1.01-2.63; p=0.046]. Additionally, pre-operative GNRI was an independent predictor of complete AC (odds ratio=0.38, 95%CI=0.17-0.83; p=0.015). In the high (≥98) and low GNRI (<98) groups, patients who underwent complete AC had significantly longer OS than those who did not (p<0.001, respectively). However, the patients in the low GNRI group who underwent complete AC had no significant difference in OS compared to those in the high GNRI group who did not undergo complete AC (p=0.523). CONCLUSION: Pre-operative GNRI may predict complete AC and prognosis in resected pancreatic cancer.

BACKGROUND: Situs inversus totalis (SIT) is a rare congenital condition that involves complete transposition (right to left reversal) of the visceral organs. Laparoscopic surgery can be challenging because of the mirror-image anatomy. We describe a surgical innovation in laparoscopic surgery for SIT. CASE PRESENTATION: A 41-year-old man with SIT was diagnosed with an appendiceal tumor and underwent laparoscopic-assisted ileocecal resection. Preoperatively, we evaluated anatomical variations using 3D-computed tomography and simulated mirror images by watching flipped videos of patients with normal anatomy undergoing similar operations. During the operation, port placement and the surgeons' standing positions were reversed. Additionally, two monitors were placed at the patient's head, with one monitor showing original images, and the other showing flipped images that looked the same as the normal anatomy. We checked the range of the mobilized region and important anatomical structures by watching the flipped monitor as needed. The patient's postoperative course was uneventful. CONCLUSIONS: Due to the complexities of laparoscopic surgery for SIT, preoperative preparation and surgical innovation are necessary for safe surgery. Several suggestions have been made to understand anatomical anomalies and improve operability; however, surgeons must focus on the mirror-image anatomy throughout the operation. Therefore, the use of intraoperative flipped monitor will be helpful for surgeons in reducing the risk of anatomical misidentification.
RESUMO
The purpose of this study was to investigate the utility of reconstructed CT images perpendicular to the artery for assessing arterial involvement from pancreatic cancer and compare the interobserver variability between it and the current diagnostic imaging method. This retrospective study included patients with pancreatic cancer in the pancreatic body or tail who underwent preoperative pancreatic protocol CT and distal pancreatectomy. Five radiologists used axial and coronal CT images (current method) and perpendicular reconstructed CT images (proposed method) to determine if the degree of solid soft-tissue contact with the splenic artery was ≤180° or >180°. The generalized estimating equations were used to compare the diagnostic performance of solid soft-tissue contact >180° between the current and proposed methods. Fleiss' ĸ statistics were used to assess interobserver variability. The sensitivity and negative predictive value for diagnosing solid soft-tissue contact >180° were higher (p < 0.001 for each) and the specificity (p = 0.003) and positive predictive value (p = 0.003) were lower in the proposed method than the current method. Interobserver variability was improved in the proposed method compared with the current method (ĸ = 0.87 vs. 0.67). Reconstructed CT images perpendicular to the artery showed higher sensitivity and negative predictive value for diagnosing solid soft-tissue contact >180° than the current method and demonstrated improved interobserver variability.
RESUMO
BACKGROUND: Advances in chemotherapy have increased clinical experience with conversion surgery for inoperable advanced gastric cancer. This report describes three patients with unresectable gastric cancer accompanied by multiple liver metastases. In all three patients, nivolumab resolved the liver metastases and subsequent conversion surgery achieved a pathological complete response. CASE PRESENTATION: In Case 1, a 68-year-old man with clinical Stage IVB gastric cancer and multiple liver metastases initiated first-line therapy with SOX plus nivolumab. The patient completed 13 cycles; however, only nivolumab was continued for 3 cycles because of adverse events. Distal gastrectomy and partial hepatic resection were performed because of a significant reduction in the size of the liver metastases as observed on magnetic resonance imaging (MRI). In Case 2, a 72-year-old man with clinical Stage IVB gastric cancer and multiple liver metastases initiated first-line therapy with SOX. Because of the subsequent emergence of new liver metastases, the patient transitioned to ramucirumab plus paclitaxel as second-line therapy. Third-line therapy with nivolumab was initiated because of side effects. MRI revealed necrosis within the liver metastasis, and the patient underwent proximal gastrectomy and partial hepatectomy. In Case 3, a 51-year-old woman with clinical Stage IVB gastric cancer accompanied by multiple metastases of the liver and para-aortic lymph nodes began first-line therapy with SOX plus nivolumab. The patient completed 10 cycles; however, only nivolumab was continued for 5 cycles because of adverse events. Computed tomography showed a significant decrease in the size of the para-aortic lymph nodes, while MRI indicated the presence of a singular liver metastasis. Distal gastrectomy and partial hepatic resection were subsequently performed. In all three cases, MRI revealed the presence of liver metastases; however, pathological examination showed no viable tumor cells. CONCLUSIONS: We herein present three cases in which chemotherapy, including nivolumab, elicited a response in patients with multiple unresectable liver metastases, ultimately culminating in R0 resection through conversion surgery. Although MRI showed liver metastases, pathological analysis revealed no cancer, underscoring the beneficial impact of chemotherapy.
