RESUMO
Aim: Intracorporeal anastomosis (IA) is becoming increasingly popular and replacing extracorporeal anastomosis (EA) for reconstruction in laparoscopic and robotic surgery for right-sided colon cancer (LSRCC). Intracorporeal overlap anastomosis (IOA) is the most widely used IA technique. This study aimed to examine the safety of IOA by investigating its short-term results during the implementation phase. Methods: This multicenter prospective cohort study was conducted by the Kanagawa Yokohama Colorectal Cancer (KYCC) Study Group. Patients with stage 1-3 colon cancer who planned to undergo LSRCC with IOA reconstruction were eligible. The incidence of anastomotic leakage (AL) of Clavien-Dindo (C-D) grade ≥3 was evaluated as the primary endpoint, and other surgical outcomes and postoperative complications of C-D grades ≥2 were the secondary endpoints. Results: A total of 127 patients were enrolled, of whom 120 were finally analyzed. The incidence of C-D grade ≥2 complications was 8.3%. The incidence of C-D grade ≥3 AL was 0.8%. This trend was lower than that reported in previous randomized controlled trials (RCTs) and acceptable. Additionally, 1.7% of the patients developed abdominal abscesses, and no cases of anastomotic stenosis were observed. The median operative time was 257 min, and the reconstruction procedure required 32 min. Stapler closure of the enterotomy and facility experience of more than 30 cases were associated with a shorter reconstruction time during IOA. Conclusion: IOA is feasible and can be safely performed during the implementation phase in patients undergoing LSRCC.
RESUMO
PURPOSE: Identification of the Adamkiewicz artery before aortic surgery is important for preventing postoperative complications due to spinal cord ischemia. The Adamkiewicz artery is difficult to identify due to its small diameter. Nitroglycerin has a vasodilatory effect and is used clinically to improve visualization of blood vessels on coronary computed tomography (CT) angiography. We investigated whether the vasodilatory effect of nitroglycerin could improve the ability to visualize the Adamkiewicz artery. METHODS: We extracted 33 cases wherein contrast-enhanced CT images were taken before and after aortic aneurysm surgery. Nitroglycerin was administered for coronary artery evaluation on the preoperative CT. However, no nitroglycerin was administered before the postoperative CT. Aortic contrast-to-noise ratio, CT value, image noise, and diameter of the Adamkiewicz artery and anterior spinal artery were measured. The depiction of the Adamkiewicz artery was graded into four grades and evaluated. These measurements were performed by two independent reviewers. RESULTS: In nitroglycerin-administered cases, the contrast-to-noise ratio and CT values were significantly higher (P < 0.001, P < 0.001, respectively); the Adamkiewicz artery and anterior spinal artery diameters were dilated (P = 0.005, P = 0.001, respectively). The Adamkiewicz artery score also improved significantly (P < 0.001). No significant difference was found in image noise. CONCLUSION: Nitroglycerin contributed to improving the Adamkiewicz artery's visualization.
RESUMO
INTRODUCTION: Indocyanine green fluorescence imaging (ICG-FI) reduces anastomotic leakage (AL) in rectal cancer surgery. However, no studies investigating risk factors for anastomotic leakage specific to the group using ICG-FI have ever previously been conducted. The purpose of this retrospective multicenter study was to ascertain the risk factors for AL in the group using ICG-FI. METHODS: A total of 638 patients who underwent laparoscopic or robotic anterior resection for rectal cancer between April 2018 and March 2023 were included in this study. Patients were divided into two groups: the ICG-FI group (n = 269) and the non-ICG-FI group (n = 369) for comparative analysis. The effects of clinicopathological and treatment-related factors on AL in the ICG-FI group were evaluated using both univariate and multivariate analyses. RESULTS: The incidence of AL in the ICG-FI group was 4.8%. Although there was no significant difference in the incidence of AL between the two groups, it was observed to be lower in the ICG-FI group. A multivariate analysis revealed a preoperative C-reactive protein-to-albumin ratio (CAR) ≥ 0.049 (odds ratio, 3.73; 95% confidence interval, 1.01-13.70; p = 0.048) as an independent risk factor for AL in the ICG-FI group. CONCLUSIONS: In this study, CAR was the only identified risk factor for AL in the ICG-FI group. It was suggested that CAR could be a criterion for early surgical intervention, prior to the escalation of risks, or for considering interventions such as diverting stoma creation.

PURPOSE: There have been no adequate comparisons of the efficacy, safety, and efficiency of analgesia after laparoscopic colorectal resection (LAC), with and without epidural anesthesia (EDA). METHODS: This was a multicenter prospective observational study of patients undergoing LAC. The primary end point was the mean visual analog scale (VAS) score on postoperative days (PODs) 1-7. The secondary end points were the highest VAS, complication rate, days to first ambulation and fatigue, length of hospital stay, and time to commencement of surgery. RESULTS: We compared an EDA group (Group E, n = 48) and a no-EDA group (Group O, n = 48) after matching. The mean VAS was not significantly different between the groups (28.7 vs. 30.1, p = 0.288). On assessing the secondary end points, the highest VAS was not significantly different between the groups. In fact, the VAS was lower in Group E only on POD 2. There was no difference in the incidence of complications, the time to first postoperative evacuation was shorter in Group E, and postoperative hospitalization was similar. The time to surgery was shorter in Group O. CONCLUSION: These results suggest that LAC without EDA is a feasible option, but with the early and regular use of adjunctive measures to provide more stable analgesia.
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.

PURPOSE: This study compared the surgical outcomes between laparoscopic colectomy (LC) and open colectomy (OC) for mid-transverse colon cancer (MTC). METHODS: This multicenter retrospective study compared the short- and long-term surgical outcomes for patients with advanced MTC (T3 and T4 with or without nodal involvement) who underwent LC or OC between January 2008 and December 2019 using a propensity score-matched analysis. RESULTS: A total of 177 patients with advanced MTC were enrolled. After matching, 58 cases for the OC and LC groups were selected. No significant differences in age, sex, tumor progression, or procedure type (extended resection or segmental resection) existed between groups. The LC group had significantly less blood loss (20 mL vs. 50 mL, p=0.048) and a shorter postoperative hospital stay (8 days vs. 12 days, p<0.001) than the OC group. Postoperative complications (Clavien-Dindo grade ≥ 2) occurred in 27.6% and 25.9% of the OC and LC groups respectively (p=1). Three patients (5.2%) and one patient (1.7%) of the OC and LC groups respectively developed anastomotic leakage (p=0.62). Re-operation was required in five patients (8.6%) in the OC group and one patient (1.7%) in the LC group (p=0.21). No surgery-related deaths occurred in either group. The 3-year overall survival rates (stage II: LC 100% vs. OC 92.8%, p=0.15; stage III: 88.9% vs. 84.3%, p=0.88, respectively) were similar between the two groups. CONCLUSION: LC is a minimally invasive technique with lesser blood loss, shorter postoperative hospital stays, and oncologic equivalence to OC. Hence, LC is useful for MTC treatment.

A 78-year-old man was aware of lightheadedness and darkness at a routine outpatient visit, and his blood pressure was declined at 87/51 mmHg. Contrast-enhanced CT scan showed an extravascular leakage image at jejunum. We diagnosed as small intestinal hemorrhage. Because he was in hemorrhagic shock, emergency surgery was performed. A tumor was found coincident with the bleeding site, and partial resection of the small intestine including enlarged lymph nodes was performed. Based on the pathological findings of T-cell origin and positive for serum anti-HTLV-1 antibody, he was suspected as adult T-cell leukemia/lymphoma(ATLL). Endoscopic examination of the upper and lower gastrointestinal tracts, bone marrow examination, and PET-CT scan were performed, but no other lesions were found. We report a case of the T-cell lymphoma with suspected solitary ATLL of the jejunum.

A 77-year-old man visited a clinic because of nausea and chest discomfort. On blood test, hepatobiliary enzymes were elevated, and he referred to our hospital. Contrast-enhanced CT revealed stenosis of the extrahepatic bile duct and brush cytology of the bile duct showed adenocarcinoma. We therefore performed pancreatoduodenectomy for extrahepatic bile duct cancer. Pathological diagnosis was small cell neuroendocrine carcinoma, pT3N2M0, Stage â ¢A. The patient did not receive adjuvant chemotherapy and 3 months later contrast-enhanced CT and MRI showed multiple liver metastases. The patient was treated with cisplatin plus irinotecan in the first-line, cisplatin plus etoposide in the second-line, and amrubicin in the third-line and accordingly he died 1 year and 3 months after the surgery. Chemotherapy for neuroendocrine carcinoma of the bile duct is recommended as in small cell lung cancer, but the prognosis is extremely poor. We report this case with a review of some of the literature.

According to the risk classification of recurrence, the standard treatment for gastrointestinal stromal tumor(GIST)is complete surgical resection and postoperative adjuvant therapy with imatinib; however, the usefulness of neoadjuvant therapy is unclear. We report a case of giant GIST in the pelvis suspectedly having bladder infiltration that was radically resected and underwent preoperative imatinib therapy. A 52-year-old man visited a clinic because of abdominal pain, fever, and frequent urination. An abdominal mass was determined, and the patient was referred to our hospital for detailed examination and treatment. Contrast-enhanced CT revealed a 17 cm diameter irregular mass from the lower navel to the pelvis, and the bladder boundary was partially unclear. Transrectal biopsy was performed using endoscopic ultrasonography, and according to the Fletcher classification, a high-risk GIST was diagnosed. After preoperative imatinib therapy of 400 mg/day was administered for 3 months, surgery was performed. The tumor was strongly adhered to the bladder, but no invasion was observed, and partial small intestine resection was performed. The surgical margin was negative without capsule damage. On day 34 postoperatively, imatinib therapy was resumed, and as of 1 year postoperatively, the course is well without recurrence.

Purpose: This study was performed to evaluate the prognostic value of preoperative C-reactive protein to albumin ratio (CAR) in older patients with colorectal cancer (CRC) undergoing curative resection. Methods: We retrospectively analyzed 244 older patients (aged 75 years or higher) with pathological stage II/III CRC who underwent curative surgery between 2008 and 2016. The optimal value of CAR was calculated and its correlation with the clinicopathological factors and prognosis was examined. Results: The optimal cutoff value of the CAR was 0.085. High preoperative CAR was significantly associated with high carcinoembryonic antigen levels (P=0.001), larger tumor size (P<0.001), and T pathological (pT) factor (P=0.001). On multivariate analysis, high CAR was independent prognostic factor for relapse-free survival (P=0.042) and overall survival (P=0.001). Conclusion: Preoperative elevated CAR could be considered as an adverse predictor of both relapse-free survival and overall survival in older patients with CRC undergoing curative surgery.
RESUMO
BACKGROUND/AIM: Postoperative complications are associated with increased recurrence in colorectal cancer (CRC). We investigated the impact of infectious complications on the recurrence of CRC and overall survival after curative surgery in a single study group. PATIENTS AND METHODS: In total, 1,668 patients who underwent radical resection for CRC in Yokohama City University, Yokohama Minami Kyosai Hospital, and Kanagawa Cancer Center between 2011 and 2019 were reviewed. Patients were classified into those with infectious complications (IC group) and those without infectious complications (Non-IC group). The risk factors for recurrence-free survival (RFS) and overall survival (OS) were analyzed. RESULTS: Postoperative complications were found in 560 of the 1,668 patients (33.5%), and IC, which occurred in 312 patients (18.7%), included pneumonia, anastomotic leakage, and intraperitoneal abscess. The 5-year OS rates in the Non-IC and IC groups were 95.5% and 90.4%, respectively, while the 5-year RFS rates were 74.4% and 68.1%, respectively. The multivariate analysis demonstrated that postoperative IC were significant independent risk factors for OS and RFS. CONCLUSION: The presence of postoperative IC after CRC resection is associated with decreased long-term survival. The surgical procedure, surgical strategy, and perioperative care should be carefully planned in order to avoid causing IC.

PURPOSE: The laparoscopic surgery approach for mid-transverse colon cancer (MTC) varies depending on tumor characteristics and the guidelines implemented by each surgeon; the optimal surgical procedure for MTC has not been established. This study aimed to compare the surgical outcomes of laparoscopic extended right hemicolectomy (Lap-ERHC) and laparoscopic transverse colectomy (Lap-TC) for MTC. METHODS: This was a multicenter, retrospective study. We surveyed eight hospitals, by questionnaire, on MTC surgery policies and retrospectively compared the short- and long-term surgical outcomes for patients with MTC who underwent Lap-ERHC or Lap-TC between January 2008 and December 2019. RESULTS: A total of 129 patients were enrolled, of whom 35 underwent Lap-ERHC and 94 underwent Lap-TC. There were no significant differences in tumor progression between the two groups. Operation time was significantly longer (202 min vs. 185 min, p = 0.026). We observed a higher complication rate (≥ grade 3) in the Lap-ERHC group than in the Lap-TC group (11.4% vs. 3.2%, p = 0.086). Three patients (8.6%) who underwent Lap-ERHC developed anastomotic leakage; none of the patients who underwent Lap-TC had this complication (p = 0.018). The 3-year overall survival rates (stage I: 100% vs. 91.9%, p = 0.64; stage II: 100% vs. 95.5%, p = 0.46; stage III: 100% vs. 88.2%, p = 0.91, respectively) were similar between the two groups. CONCLUSION: Lap-ERHC for MTC has the same long-term outcomes as Lap-TC. However, Lap-ERHC for MTC has a higher complication rate. Therefore, Lap-TC may be recommended for patients with MTC.

Since leptomeningeal carcinomatosis is rarely observed before diagnosis of the primary cancer, its detection is often delayed. We report the case of a 60-year-old woman who presented with lung adenocarcinoma with leptomeningeal carcinomatosis. Magnetic resonance imaging showed the characteristic abnormal hyperintensity along the ventral surface of the brain stem on fluid-attenuated inversion recovery and diffusion weighted imaging. It had no contrast uptake. Based on these findings, we were able to make an early diagnosis of leptomeningeal carcinomatosis of lung adenocarcinoma. This condition was resolved after treatment with a tyrosine kinase inhibitor.
RESUMO
BACKGROUND AND OBJECTIVES: Contrary to the Japanese guidelines recommendations regarding lateral lymph node dissection (LatLND) for rectal cancer, its omission is common in clinical practice without reliable omission criteria. Negative pathological mesorectal lymph node metastasis (MesLNM) is reportedly highly correlated with negative pathological lateral lymph node metastasis (p-LatLNM); however, this cannot be used as a criterion because pathological features are revealed postoperatively. Herein, we prospectively evaluated the negative predictive value (NPV) of MesLNM diagnosed via the one-step nucleic acid amplification (OSNA) method for p-LatLNM. METHODS: This prospective study was conducted at a single academic study group in Japan. The key eligibility criterion was mid-to-low rectal cancer planned to be treated using mesorectal excision with LatLND. According to the study protocol, the OSNA method was considered useful if the point estimate of the NPV exceeded 95%. RESULTS: Preoperative case registration was conducted between 2018 and 2020; 34 patients were registered. Among these, 16 were negative for OSNA-MesLNM, and negative p-LatLNM was confirmed in all cases. The point estimate of the NPV was 100%, with the 95% confidence interval ranging from 79.4% to 100.0%. CONCLUSIONS: The OSNA method is useful in selecting patients in whom LatLND can be omitted in real-world clinical practice.

BACKGROUND: Resection of the primary lesion with radical lymph node dissection is the most promising treatment avenue for patients with cancer. On the other hand, these procedures often induce excessive intraoperative blood loss (IBL) and require perioperative blood transfusion. The influence of IBL on the long-term postoperative outcomes of patients with digestive cancer is controversial. We investigated the impact of IBL on survival and recurrence after curative surgery in patients with colorectal cancer (CRC) in a single study group. PATIENTS AND METHODS: In total, 1,597 patients who underwent radical resection for CRC at three group hospitals between 2000 and 2019 were reviewed. Patients were classified into a group with high IBL (≥200 ml) or low IBL (<200 ml). The risk factors for disease-free (DFS) and overall (OS) survival were analyzed. RESULTS: A total of 489 and 1,108 patients were classified into the high and low IBL groups, respectively. The OS and DFS rates at 5 years after surgery were 89.3% and 63.4%, respectively, for the high IBL group and 96.9% and 77.8% for the low IBL group; these differences were statistically significantly (p<0.001). The multivariate analysis demonstrated that IBL was a significant independent risk factor for OS and DFS. CONCLUSION: The amount of IBL was associated with significant differences in the OS and DFS of patients with stage II/III CRC who received curative resection. The surgical procedure, surgical strategy, and perioperative care should be carefully planned to avoid causing IBL.

We experienced a case of kidney metastasis of a gastric tumor. An 81-year-old man underwent distal gastrectomy with D2 lymph node dissection and partial hepatic resection for antral gastric tumor with hepatic infiltration in July 2019. A histological examination showed undifferentiated tubular adenocarcinoma. The final stage was pT4bN1P0H0M0, Stage â ¢B. He rejected the recommended adjuvant chemotherapy. Seven months after surgery, abdominal enhanced CT showed a hypovascular mass, 20 mm in diameter, on the right upper pole of kidney. Eleven months after surgery, CT showed that the mass had enlarged to 35 mm, infiltrated the renal pelvis, and advanced to para-aortic lymph node metastasis. We performed a retroperitoneoscopic partial right nephrectomy and diagnosed kidney metastasis of the gastric tumor. His right flank pain worsened, and radiotherapy(50 Gy)was performed for the mass and para-aortic lymph node metastasis. His right flank pain resolved. Kidney metastasis of the gastric tumor is very rare. Radiotherapy effectively relieves pain.

A 65-year-old woman underwent distal gastrectomy with D2 lymph node dissection for advanced gastric cancer in November 2016. The histopathological diagnosis was pT3N0M0, pStage â ¡A, HER2-negative. In August 2019, transverse colon stenosis due to peritoneal dissemination was detected, and an ileum-transverse colon anastomosis was performed. Postoperatively, she received chemotherapy with S-1 plus oxaliplatin. After 6 courses, CT revealed an increase in ascites and dissemination nodules. We diagnosed her with progressive disease and initiated second-line chemotherapy, a ramucirumab plus nab-paclitaxel regimen. On the 20th day during the 5th course of treatment, she visited our hospital with acute abdominal pain. CT revealed free air, and we diagnosed acute panperitonitis with a gastrointestinal perforation. Emergency surgery was performed, and perforation of the appendix end and mild cloudy ascites were observed. We performed an appendectomy and intraperitoneal drainage. Histopathological examination revealed perforation of the appendix, possibly as an adverse effect of the ramucirumab. It should be noted that angiogenesis inhibitors may cause the fatal adverse effect of gastrointestinal perforation.

Chylothorax after esophagectomy is a relatively rare complication that can be difficult to manage. Here, we report a case of refractory chylothorax after surgery for esophageal cancer treated with lymphatic duct lipiodol imaging by inguinal lymph node puncture to confirm patency of the thoracic duct and thoracic duct ligation. A 71-year-old female with esophageal cancer(cT3N0M0)underwent video-assisted thoracoscopic esophagectomy with 2-field lymph node dissection, intrathoracic gastric tube reconstruction, and an enterostomy. A chylothorax appeared when we started enteral nutrition on the day after surgery. She became markedly dehydrated due to over 2,000 mL/day of drainage from the chest drain, and we managed her general condition in the ICU. We started octreotide acetate on postoperative day(POD)6 and etilefrine on POD 8, but neither was effective. Lymphatic duct lipiodol imaging by bilateral inguinal lymph node puncture was performed, and we confirmed leakage from the main thoracic duct. On POD 11, a thoracic duct ligation performed via a thoracotomy revealed that the volume of the chylothorax was remarkably decreased. The chest tube was removed on re-POD 12.
