RESUMO
BACKGROUND: Hepatectomy is currently recommended as the most reliable treatment for colorectal liver metastases. However, the association between the choice of treatment for recurrence and the timing of recurrence remains controversial. METHODS: Two-hundred ninety-five patients who underwent hepatectomy were retrospectively analyzed for the risk factors and the outcomes for early recurrence within 6 months. The remnant liver volumes (RLVs) and laboratory data were measured postoperatively using multidetector computed tomography on days 7 and months 1, 2, and 5 after the operation. RESULTS: Early recurrence developed in 88/295 patients (29.8%). Colorectal cancer lymph node metastasis, synchronous liver metastasis, and multiple liver metastases were independent risk factors for the occurrence of early recurrence (p < 0.001, 0.032, and 0.019, respectively). Patients with early recurrence had a poorer prognosis than did patients who developed later recurrence (p < 0.001). Patients who underwent surgery or other local treatment had better outcomes. The changes in RLV and laboratory data after postoperative month 2 were not significantly different between the 2 groups. CONCLUSION: Patients with early recurrence within 6 months had a poorer prognosis than did patients who developed later recurrence. However, patients who underwent repeat hepatectomy for recurrence had a better prognosis than did those who underwent other treatments, with good prospects for long-term survival.

INTRODUCTION: The rising proportion of elderly patients (aged 80 yearsor above) in our population means that more elderly patients are undergoing hepatectomy. METHODS: Five-hundred and thirty patients who underwent hepatectomy for hepatocellular carcinoma (HCC) were retrospectively analyzed with respect to their preoperative status and perioperative results, including remnant liver regeneration. The remnant liver volume was postoperatively measured with multidetector CT on postoperative day 7 and 1, 2, 5, and 12 months after surgery. An elderly group (aged 80 or older) was compared with a non-elderly group (aged less than 80 years). RESULTS: Underlying diseases of the cardiovascular system were significantly more common in the elderly group (57.8%, p = 0.0008). The postoperative incidence of Clavien-Dindo Grade IIIa or higher complications was 20.0% in the elderly group and 24.3% in the non-elderly group, and this difference was not significant. As for regeneration of the remnant liver after resection, this was not morphologically delayed compared to the non-elderly group. CONCLUSIONS: In this study, we have demonstrated that safe, radical hepatectomy, similar to procedures performed on non-elderly patients, can be performed on patients with HCC aged 80 and older with sufficient perioperative care.

The use of surgical treatment for refractory isolated gastric varices has decreased owing to the development of endoscopic and radiologic procedures, although surgeries are sometimes required as the final method. A 75-year-old Japanese woman was diagnosed with solitary gastric varices. Initially, intraoperative splenic artery embolization was performed using the balloon transcatheter technique under general anesthesia. Laparoscopic splenectomy was performed safely owing to preoperative splenic artery embolization. Intraoperative indocyanine green (ICG) fluorescence angiography was performed following the injection of 5 mL of ICG; the remnant stomach was observed using laparoscopic equipment with an ICG imaging system, and blood flow from the remnant gastric artery was confirmed. The blood did not pool or wash out immediately, which confirmed successful devascularization of the stomach. The total operative time was 269 minutes, and the intraoperative blood loss was 500 mL. The patient's postoperative course was good, and at 21 days after the last operation, she was discharged from our hospital in remission. Real-time fluorescence angiography with ICG is a reliable and objective technique of assessing blood flow of the stomach. Accurate, extensive devascularization in the lower esophagus and upper stomach was performed using Hassab's procedure in combination with ICG imaging.

BACKGROUND: There is no consensus about remnant liver regeneration associated with middle hepatic vein (MHV) resecting. METHODS: Seventy-five patients who underwent hemihepatectomy were retrospectively analysed with respect to remnant liver regeneration. The liver remnant volume (LRV) and each sectional volume were postoperatively measured with multidetector computed tomography at day 7 and months 1, 2, 5, and 12 after the operation. RESULTS: In right hemihepatectomy cases, the regeneration rate of LRV in the MHV preservation group was significantly higher than that of the MHV resection group at months 5 and 12. In particular, the regeneration rate of remnant segment IV peaked at day 7 and was shrunk after 1 month, and was significant higher in the MHV preservation group. In left hemihepatectomy cases, the regeneration rate of LRV at month 12 was significantly higher in the MHV preservation group. The regeneration rate of the remnant anterior section peaked at 1 month and was shrunk. CONCLUSION: In this study, the MHV should be preserved or reconstructed whenever possible during hepatic hemihepatectomy. Hepatic regeneration in the MHV perfusion region becomes poor within 7 days to 1 month after surgery (UMIN000023714).

BACKGROUND: Various chemotherapy regimens have been shown to improve outcomes when administered before tumor excision surgery. However, there is no consensus on the utility of multidisciplinary treatment with preoperative chemotherapy for treating colorectal liver metastasis (CLM). MATERIALS AND METHODS: Two hundred-fifty patients who underwent hepatectomy were retrospectively analyzed using propensity score matching. Postoperative outcomes were evaluated with a focus on the effect of pre-hepatectomy chemotherapy on regeneration of the remnant liver in patients with CLM. The remnant liver volumes (RLVs) were postoperatively measured with multidetector computed tomography on days 7 and months 1, 2, 5, and 12 after the operation. RESULTS: RLV regeneration and blood test results did not significantly differ between patients who underwent preoperative chemotherapy versus those who did not immediately after surgery or at any time point from postoperative day 7 to postoperative month 12. The 1-, 2-, and 3-year overall survival (OS) rates for all patients were 94.6, 86.2, and 79.9%, respectively; the corresponding disease-free survival (RFS) rates were 49.3, 38.6, and 33.7%, respectively. There were no significant differences in OS and RFS between the two groups after hepatic resection. The recurrence rates, including marginal and intrahepatic recurrences, as well as resection frequency of the remnant liver were not significantly different between the two groups. CONCLUSION: Preoperative chemotherapy may have no appreciable benefit for patients with CLM in terms of perioperative and long-term outcomes.

AIM OF THE STUDY: Despite recent technical progress and advances in the perioperative management of liver surgery, postoperative surgical site infection (SSI) is still one of the most common complications that extends hospital stays and increases medical expenses following hepatic surgery. MATERIAL AND METHODS: From 2001 to 2017 a total of 1180 patients who underwent hepatic resection for liver tumours were retrospectively analysed with respect to the predictive factor of superficial incisional SSI, using a propensity score matching by procedure (subcuticular or mattress suture). RESULTS: The incidence of superficial and deep incisional SSIs was found to be 7.1% (84/1180). By propensity score matching (PSM), 121 of the 577 subcuticular suture group patients could be matched with 121 of the 603 mattress suture group patients. Multivariate analysis demonstrated wound closure technique as the only independent risk factor that correlated significantly with the occurrence of superficial incisional SSIs (p = 0.038). C-reactive protein (CRP) levels on postoperative day 4 were significantly higher in patients with incisional SSIs than in those without (p < 0.001). CONCLUSIONS: Wound closure technique with subcuticular continuous spiral suture using absorbable suture should be considered to minimise the incidence of incisional SSIs. Moreover, wounds should be carefully checked when CRP levels are high on postoperative day 4.
RESUMO
This case report discusses a 48-year-old woman with metastatic breast cancer: T4c(10.5 cm)N2bM1,(OSS, LYM), stage IV, estrogen receptor(ER)(+), progesterone receptor(PgR)(+), human epidermal growth factor receptor-2(HER2) (-), and Ki-67 17.2%. Administration of eribulin was initiated after treatment with anthracycline and taxane. Thereafter, 28 courses of eribulin maintained a SD state for over a year and improved the quality of life(QOL). Eribulin is effective for both prolonging life and improving QOL, which are the main goals in the treatment of metastatic or recurrent cancer. Therefore, this evidence suggests that eribulin can be effective in various clinical situations.

A 68-year-old woman presented with general malaise. Her vital signs were unstable, and abdominal computed tomography revealed giant (10 cm) splenic artery aneurysm with evidence of rupture. We first occluded the root of the splenic artery using a balloon catheter. Next, we resected the distal pancreas and spleen because of the aneurysm size and destruction of the related vasculature. After surgery, the patient's condition improved, and she was discharged from the hospital on postoperative day 18. Because ruptured giant splenic artery aneurysms are very rare, we report this case with a review of the literature.

The models used to investigate the pathophysiological mechanisms of acute critical illness are not limited to mammalian species. The zebrafish (Danio rerio) is a popular model organism for studying diseases due to its transparency and rapid development. The genes and signaling pathways involved in acute critical illness appear highly conserved among zebrafish and humans. Forward genetics such as random mutagenesis by a chemical mutagen or reverse genetics methods represented by CRISPR/Cas9 allowed researchers to reveal multiple novel aspects of pathological processes in areas including infection, immunity, and regeneration. As a model of sepsis, transgenic zebrafish allowed the visualization of lipopolysaccharide (LPS)-induced vascular leakage in vivo and the demonstration of changes in the expression of cellular junction proteins. Other transgenic zebrafish visualizing the extravascular migration of neutrophils and macrophages have demonstrated a decrease in neutrophil numbers and an increased expression of an inflammatory gene, which replicates a phenomenon observed in humans in clinically encountered sepsis. The regenerative potential and the visibility of zebrafish organs also enabled clarification of important mechanisms in wound healing, angiogenesis, and neurogenesis. After spinal cord injury (SCI), a marker gene expressed in glial bridging was discovered. Furthermore, localized epithelial-to-mesenchymal transition (EMT) and molecular mechanisms leading to spinal cord repair were revealed. These translational studies using zebrafish show the potential of the model system for the treatment of acute critical illnesses such as sepsis, organ failure, and trauma.
RESUMO
PURPOSE: Of the various methods used, the laparoscopic surgical repair of inguinal hernias is widely performed. We aimed to estimate the incidence of bilateral and contralateral occult inguinal hernias in our surgical population and to compare the results of total extraperitoneal repair (TEP) for bilateral and unilateral inguinal hernias, occult and non-occult hernias. METHODS: We retrospectively reviewed data of patients who underwent TEP for the repair of adult inguinal hernias from January 2012 to November 2018 in our hospital. RESULTS: Of the data of 259 patients included, 134 (51.7%) and 125 (48.3%) had unilateral and bilateral inguinal hernias, respectively, while 70 patients (27%) were found to have a contralateral occult inguinal hernia, intraoperatively. The mean operative time was 129 ± 48 minutes (range, 43-300 minutes) and 167 ± 55 minutes (range, 85-390 minutes) for the unilateral and bilateral groups, respectively, indicating a significantly longer duration of surgery for the bilateral group (P < .05). Recurrence occurred in 1.5% (5/134) and 0.4% (1/250) of the operated hernias in the unilateral and the bilateral groups, respectively, indicating a significantly lower rate of recurrence in the latter group (P < .05). The two groups showed no statistically significant differences with respect to the remaining perioperative data. The incidence of postoperative complications in occult hernias was not significantly different from that in non-occult hernias. CONCLUSIONS: Our TEP method, involving a laparoscopic exploration from the intraperitoneal side, can be safely and effectively utilized for the repair of both bilateral and contralateral occult inguinal hernias.

Introduction: The Pringle manoeuvre is used in most hospitals to counteract intraoperative haemorrhage in laparoscopic hepatectomy by occluding the flow of blood to the liver. However, in laparoscopic repeat hepatectomy (LRH), outcomes of previous surgery and the influence of other factors frequently make it difficult to occlude the inflow of blood. Aim: To discuss the value of inflow occlusion during LRH and provide tips for its performance. Material and methods: Sixty-three patients who underwent LRH with or without the Pringle manoeuvre were analysed retrospectively. We investigated the efficacy and safety of the Pringle manoeuvre in LRH. Student's t and χ2 tests, Mann-Whitney's U test, Wilcoxon's signed-rank test, and Fisher's exact test were used in the statistical analysis. Results: Nineteen patients underwent LRH with the Pringle manoeuvre, and 44 patients underwent LHR without the Pringle manoeuvre. After propensity score matching, there were no significant differences in terms of operative time, estimated blood loss, and postoperative complication rate (p = 0.973, 0.120, and not applicable, respectively). However, the rate of conversion to open repeat hepatectomy (ORH) was significantly lower in the Pringle manoeuvre group (p = 0.034). In many cases, the cause of conversion to ORH was the non-use of inflow occlusion and the resulting inability to control intraoperative haemorrhage. Laboratory data collected after surgery showed no significant difference between the 2 groups regardless of whether blood flow was occluded or not. Conclusions: LRH with the Pringle manoeuvre can be performed safely using various surgical devices. However, it is often challenging to perform the Pringle manoeuvre in patients with a history of cholecystectomy or segment 5 resection of the liver, and caution is required.
RESUMO
BACKGROUND: Hepatectomy is currently recommended as the most reliable treatment for hepatocellular carcinoma. However, the association between the choice of treatment for recurrence and the timing of recurrence remains controversial. METHODS: Three-hundred thirty-nine patients who underwent hepatectomy were retrospectively analyzed using a propensity score matching analysis for the risk factors and outcomes for early recurrences within 6 months. The remnant liver volumes and laboratory data were measured postoperatively using multidetector computed tomography on days 7 and months 1, 2, and 5 after surgery. The Student's t test and chi-square test, the likelihood-ratio test, Fisher's exact test, Mann-Whitney U test, or Wilcoxon signed-rank test were used in the statistical analyses. RESULTS: Early recurrence developed in 41/312 patients (13.1%). Vascular invasion and non-curative resection were independent risk factors for the occurrence of early recurrence (P < 0.001 and < 0.001, respectively). Patients with early recurrence had a poorer prognosis than patients who developed later recurrences (P < 0.001). Patients who underwent surgery or other local treatments had better outcomes (P < 0.001). The changes in remnant liver volumes and laboratory data after postoperative month 2 were not significantly different between the two groups. CONCLUSION: Patients with early recurrence within 6 months had a poorer prognosis than patients who developed a later recurrence. However, patients who underwent repeat hepatectomy for recurrences had a better prognosis than did those who underwent other treatments, with good prospects for long-term survival.

INTRODUCTION AND IMPORTANCE: The prognosis of non-invasive intraductal papillary mucinous neoplasma (IPMN) is better than that of pancreatic cancer. However, if the first surgical finding revealed an invasive IPMC, the risk of recurrence was found to be 7-21%. CASE PRESENTATION: A 76-year-old Japanese man had undergone subtotal stomach-preserving pancreaticoduodenectomy for intraductal papillary mucinous carcinoma non-invasive type at our hospital. No signs of adenocarcinoma at the resection margin were found by pathological examination of frozen sections. Five years later, a blood analysis showed increased serum CA19-9 level. A contrast-enhanced computed tomography scan of the abdomen revealed a mass adjacent to the pancreaticogastrostomy anastomosis. The patient underwent a total pancreatectomy. The tumor was identified as a recurrent IPMC with subserosal invasion, but without nodal involvement. The resection margins were negative. The patient's postoperative course was uneventful, and he was discharged after 12 days. He is being followed up without adjuvant chemotherapy. DISCUSSION: The prognosis of IPMN is better than that of pancreatic cancer. However the risk of recurrence in invasive IPMC was found to be 7-21%. Therefore, IPMC must be surveilled every three months using tumor markers and imaging. Local recurrence in remnant pancreas is usually treated with systemic therapy. The median long-term survival after total pancreatectomy (range 7-24 months) was shown to be better than when chemotherapy alone was used (range 10-13 months). CONCLUSION: We chose secondary surgery in term of survival time although there are quality of life drawbacks that currently make total pancreatectomy more inappropriate in patients than chemotherapy.
RESUMO
We describe the case of a 78-year-old man with collision tumor from the primary malignant lymphoma and adenocarcinoma in the ascending colon. He suffered anemia from sigmoid colon cancer, and colonoscopy revealed early-stage colorectal cancer with a diameter of 20 mm in the cecum, the biopsy specimen showed moderately differentiated adenocarcinoma. Contrast-enhanced computed tomography (CT) revealed bowel wall thickening with contrast enhancement at the cecum; however, no lymph node and organ metastases were found. As above, we performed laparoscopic ileocecal resection with D3 lymph node dissection. The postoperative course was uneventful, and he was discharged from the hospital on postoperative day 11. Histopathological findings were moderately differentiated adenocarcinoma which invaded the muscularis propria and serosa from the submucosa, while the adjacent serosa showed a highly diffuse proliferation of atypical cells with an irregular nuclear-to-cytoplasmic ratio. Besides, immunohistochemical staining findings were diffuse large B-cell lymphoma, and diffuse large B-cell lymphoma was coexistent with moderately differentiated adenocarcinoma. We treated the patient with cyclophosphamide, doxorubicin, vincristine, and prednisolone in combination with rituximab (R-CHOP therapy) during 3 months postoperatively. When the 8 courses had been completed, postoperative positron emission tomography-CT (PET-CT) confirmed complete response, and the disease control has been doing well. Malignant lymphoma of the colorectal region is relative rare, and the occurrence of synchronous lymphoma and adenocarcinoma of the colon is also rare. Furthermore, collision tumor by these different entities is very unusual. We presented here such a case. The accurate clinical determination of the dominant tumor and a close follow-up is required for proper treatment in these cases.
RESUMO
Hippocampal infarction is relatively rare. Many different diseases can mimic hippocampal infarction including transient global amnesia, Alzheimer's disease, epilepsy, encephalitis, and encephalopathies. An 89-year-old man was transported to our hospital for altered consciousness. Diffusion-weighted magnetic resonance imaging revealed slightly intense signals in the hippocampus with a mildly decreased apparent diffusion coefficient. Serial magnetic resonance imaging revealed features of hippocampal infarction. Symptoms and cognitive function gradually improved with rehabilitation, and he was transferred to a rehabilitation facility on Hospital Day 38. Hippocampal infarction is rare in patients with altered mental status, but should be considered when magnetic resonance imaging shows findings suggestive of this condition. Other differential diseases should be ruled out by serial magnetic resonance imaging and observation of the clinical course.
RESUMO
The seasonal incidence of acute abdomens, such as appendicitis, is reportedly more common in summer but is reported less frequently in Asia. Additionally, seasonal variations in the severity of acute abdomens have been evaluated insufficiently. This study evaluated the seasonal variations in the incidence and severity of acute abdomens in Japan. This retrospective observational study used a multicenter database containing data from 42 acute hospitals in Japan. We included all patients diagnosed with acute appendicitis, diverticulitis, cholecystitis, and cholangitis between January 2011 and December 2019. Baseline patient data included admission date, sequential organ failure assessment score, presence of sepsis, and disseminated intravascular coagulation. We enrolled 24,708 patients with acute abdomen. Seasonal admissions for all four acute abdominal diseases were the highest in summer [acute appendicitis, (OR = 1.35; 95% CI = 1.28-1.43); diverticulitis, (OR = 1.23; 95% CI = 1.16-1.31; cholecystitis (OR = 1.23; 95% CI = 1.11-1.36); and cholangitis (OR = 1.23; 95% CI = 1.12-1.36)]. The proportion of patients with sepsis and disseminated intravascular coagulation as well as the total SOFA score for each disease, did not differ significantly across seasons. Seasonal variations in disease severity were not observed.
RESUMO
BACKGROUND: Hepatectomy has a high risk of perioperative bleeding due to the underlying disease. Here, we investigated the postoperative impact of allogeneic blood transfusion during hepatectomy. METHODS: The surgical outcomes in 385 patients who underwent hepatic resection for hepatocellular carcinoma were retrospectively reviewed. The association of allogeneic blood transfusion with surgical outcomes and remnant liver regeneration data was analyzed. RESULTS: Eighty-six patients (24.0%) received an allogeneic blood transfusion and 272 patients (76.0%) did not. After propensity score matching, the incidence rates of postoperative complication (Clavien-Dindo grade >IIIA), posthepatectomy liver failure, and massive ascites were significantly higher for the group that received a blood transfusion than for the group that did not receive blood transfusion (P < .001, P = .001, and <.001, respectively). Postoperative measures of total bilirubin, albumin, platelet count, prothrombin time, aspartate aminotransferase, and alanine aminotransferase were significantly more favorable in patients without blood transfusion until day 7 after surgery. There were no correlations in the remnant liver regeneration at 7 days, and 1, 2, 5, and 12 months postoperatively between the 2 groups (P = .585, .383, .507, .261, and .430, respectively). Regarding prognosis, there was no significant difference in overall and recurrence-free survival between the 2 groups (P = .065 and .166, respectively). CONCLUSION: Allogeneic transfusion during hepatectomy strongly affected remnant liver function in the early postoperative period; however, this was not related to the remnant liver regeneration volume. Despite that the allogeneic transfusion resulted in poorer postoperative laboratory test results and increased postoperative complication and mortality rates, it had no effect on the long-term prognosis.

INTRODUCTION: Laparoscopic liver resection (LLR) in obese patients has been reported to be particularly challenging owing to technical difficulties and various comorbidities. METHODS: The safety and efficacy outcomes in 314 patients who underwent laparoscopic or open nonanatomical liver resection for colorectal liver metastases (CRLM) were analyzed retrospectively with respect to the patients' body mass index (BMI) and visceral fat area (VFA). RESULTS: Two hundred and four patients underwent LLR, and 110 patients underwent open liver resection (OLR). The rate of conversion from LLR to OLR was 4.4%, with no significant difference between the BMI and VFA groups (P = .647 and .136, respectively). In addition, there were no significant differences in terms of operative time and estimated blood loss in LLR (P = .226 and .368; .772 and .489, respectively). The incidence of Clavien-Dindo grade IIIa or higher complications was not significantly different between the BMI and VFA groups of LLR (P = .877 and .726, respectively). In obese patients, the operative time and estimated blood loss were significantly shorter and lower, respectively, in LLR than in OLR (P = .003 and < .001; < .001 and < .001, respectively). There was a significant difference in the incidence of postoperative complications, organ/space surgical site infections, and postoperative bile leakage between the LLR and OLR groups (P = .017, < .001, and < .001, respectively). CONCLUSION: LLR for obese patients with CRLM can be performed safely using various surgical devices with no major difference in outcomes compared to those in nonobese patients. Moreover, LLR has better safety outcomes than OLR in obese patients.

BACKGROUND: Stoma-related complications are not rare, whereas the spontaneous perforation of the stoma limb is relatively rare. Herein, we report a case of stoma limb perforation which occurred after Hartmann's operation. CASE PRESENTATION: A 50-year-old Japanese man presented to our Hospital with acute and severe abdominal pain. Abdominal computed tomography (CT) scan revealed that an abscess with free air was formed around the sigmoid colon. We performed Hartmann's operation, whereas he experienced redness, purulent discharge, and swelling around the colostomy at 10 days postoperatively. The contrast-enhanced CT scan of the abdomen revealed an abscess formation with air around the colostomy. He was diagnosed with an abdominal wall abscess due to perforation of the stoma limb. After the drainage, his symptoms were ameliorated by oral analgesics, anti-inflammatory drugs, and prophylactic antibiotic. Four months after the first operation, we performed a closedown of the sigmoid colostomy and fistula resection. The patient's postoperative course was uneventful, and he was discharged 14 days later. CONCLUSIONS: This case depicts rare complications of Hartmann's operation. Operation is usually performed in patients with stoma limb perforation. However, if they are stable and the abscess is located in their abdominal wall, they may be treated successfully using a multi-stage approach of local drainage toward the stoma wall followed by stoma closure.
RESUMO
INTRODUCTION: Peritoneal tear (PT) is a frequent intraoperative event during totally extraperitoneal repair (TEP). We aimed to introduce our surgical technique for PT during TEP to avoid the more difficult TEP procedure.MethodsOne surgeon with 10 years of experience performed our TEP method in 147 TEP cases from January 2012 to June 2019. We investigated the repair time of each repair technique using endoscopic suturing (suturing group, SG) and endoscopic Hem-o-lok stapling (CG). RESULTS: Twenty-three (15.6%) PT cases occurred as TEP complication. The mean repair times (with standard deviation) of the PT were 16.2 ± 13 and 7.6 ± 7.0 min in the SG and CG, respectively, indicating a significant difference (P = 0.043). The repair time of the PT using Hem-o-lok (Teleflex, Wayne, PA, USA) stapling was shorter than that using endoscopic suturing, which was significantly different despite the length of the PT. CONCLUSION: Hem-o-lok stapling is feasible in case of PT during TEP.
