Multicenter analysis of the efficacy of early cholecystectomy and preoperative cholecystostomy for severe acute cholecystitis: a retrospective study of data from the multi-institutional database of the Hiroshima Surgical Study Group of Clinical Oncology.

BACKGROUND: Severe acute cholecystitis (AC) is a challenging disease because it comprises coexisting systemic infections that lead to vital organ dysfunction. This study evaluated the optimal surgical timing and efficacy of preoperative percutaneous cholecystostomy (PC) for patients with severe AC. METHODS: Data of 142 patients who underwent cholecystectomy for severe AC between 2011 and 2021 were retrospectively collected from the multi-institutional database of the Hiroshima Surgical Study Group of Clinical Oncology. Patients were divided into the early cholecystectomy (EC) group (within 72 h of symptom onset) and delayed cholecystectomy (DC) group. They were also subdivided into the upfront cholecystectomy group and preoperative PC before cholecystectomy group. The diagnosis and severity of AC were graded according to the Tokyo Guidelines 2018. Clinicopathological variables and outcomes were compared. RESULTS: No significant differences in age, body mass index, American Society of Anesthesiologists (ASA) classification, and Charlson comorbidity index between the EC and DC groups were observed. Preoperative drainage was more commonly performed for the DC group than for the EC group. Local severe AC features were more commonly detected in the DC group than in the EC group. The postoperative outcomes of the EC and DC groups were comparable. Compared to the PC before cholecystectomy group, the upfront cholecystectomy group included more patients with ASA physical status ≥ 3 and more patients who used oral warfarin. Warfarin usage and cardiovascular dysfunction rates of the PC after cholecystectomy group were higher than those of the upfront cholecystectomy group. PC was associated with significantly less intraoperative bleeding and shorter hospital stays. CONCLUSIONS: Patients who can tolerate general anesthesia are good candidates for EC. Patients who use warfarin and those with cardiovascular dysfunction are considered to be at high risk for postoperative complications; therefore, to prevent AC recurrence during the waiting period, PC before cholecystectomy during the same admission is more appropriate than upfront cholecystectomy for these patients.

Prognosis of repeat hepatectomy for liver transplantable hepatocellular carcinoma recurrence after hepatectomy: a Retrospective Cohort Study with the Hiroshima Surgical Study Group of Clinical Oncology (HiSCO).

PURPOSE: Factors affecting the prognosis of repeat hepatectomy for transplantable hepatocellular carcinoma (HCC) recurrence after hepatectomy remain unclear. We aimed to clarify the prognostic factors for transplantable hepatocellular carcinoma recurrence after hepatectomy. METHODS: We included 1758 primary and 486 repeat hepatectomies out of 2244 for HCC performed between 2006 and 2017 using the Hiroshima Study Group for Clinical Oncology and Surgery database. We first compared survival rates of primary and repeat hepatectomy patients. Subsequently, prognostic factors were analyzed in patients who underwent a repeat hepatectomy for transplantable hepatocellular carcinoma recurrence after hepatectomy (defined as age < 70 years at the time of recurrence and recurrent tumor morphology that meets the Milan criteria). RESULTS: The 5-year overall survival rate (OS) after repeat hepatectomy was 63.2%, while the 5-year recurrence-free survival rate (RFS) was 23.7%. RFS demonstrated significant inferiority in the repeat hepatectomy group than in the primary hepatectomy group; however, OS did not present a notable difference between the two cohorts. In the transplantable recurrence group, mALBI grade 2b, max tumor size > 20 mm, and multiple tumors were independent prognostic risk factors for overall survival. Patients with two or more risk factors had a significantly lower survival rate (only 30.6% at 5 years) compared to those with one or fewer risk factors (81.8% at 5 years). CONCLUSIONS: We identified the risk factors involved in post-hepatectomy survival for patients with transplantable recurrence after hepatectomy. The results are a potential indicator of whether salvage liver transplantation should be considered during repeat hepatectomy.

[A Case of Extranodal NK/T-Cell Lymphoma with Perforation of the Small Intestine].

A rare case of extranodal NK/T-cell lymphoma(ENKL)with small intestinal perforation is reported. A 92-year-old man was admitted for a loss of consciousness. Computed tomography(CT)scan revealed the presence of an intraperitoneal abscess that was drained. Two days later, the drained fluid changed to intestinal juice, and intestinal perforation was suspected. The patient underwent surgery which revealed a 1 cm perforation site in the ileum. A high fever continued after surgery, and malignant lymphoma was diagnosed from pathological findings; however, further treatment could not be performed. He died 24 days after the operation. Pathological dissection revealed metastasis of ENKL at the systemic lymph nodes.

Comparison of new prognostic systems for patients with resectable hepatocellular carcinoma: Albumin-Bilirubin grade and Albumin-Indocyanine Green Evaluation grade.

AIM: We aimed to compare the prognostic abilities of two novel liver function-estimating models, Albumin-Bilirubin (ALBI) and Albumin-Indocyanine Green Evaluation (ALICE) grades, in patients with hepatocellular carcinoma. METHODS: Data of 1270 patients who underwent initial hepatectomy for hepatocellular carcinoma between 1986 and 2016 were retrospectively collected from a multi-institutional database. The prognostic impact of each system was analyzed according to the results of the area under the receiver operating characteristic curve, the Cox regression model and the linear trend χ2 -test. RESULTS: The ALBI and ALICE scores, which were obtained before grading status, were significantly correlated (correlation coefficient 0.930; P < 0.001). Both ALBI and ALICE grades stratified well in terms of overall survival, and were found to be independent prognostic factors on multivariate analysis (P < 0.05). The area under the receiver operating characteristic curves for 5-year survival in both groups were equivalent (0.602 vs. 0.614, P = 0.402); however, homogeneity, discriminatory ability, and the Akaike information criterion were superior for the ALICE grade than for the ALBI grade (73.8 vs. 65.7, 43.4 vs. 34.9, and 7204.1 vs. 7212.2, respectively). CONCLUSIONS: Both grading systems could estimate the liver function of patients with hepatocellular carcinoma. Regarding hepatectomy patients, the ALICE grade was a more suitable model than the ALBI grade.

Prediction of recurrence following hepatectomy in patients with hepatitis C virus infection-related hepatocellular carcinoma who achieved a sustained virological response.

AIM: The risk of hepatitis C virus infection-related hepatocellular carcinoma (HCC) is lower, with a better prognosis, in patients who achieve a sustained virological response (SVR) than in those who do not. We aimed to identify risk factors of post-hepatectomy HCC recurrence in patients who achieved a SVR. METHODS: This retrospective study included 349 HCC patients who underwent an initial radical hepatectomy at our institution between January 2005 and December 2014. Sixty-eight patients had achieved a SVR (the SVR group) and 281 patients had not (the non-SVR group). Clinical characteristics and long-term outcomes were compared between the two groups. Univariate and multivariate analyses identified variables associated with recurrence-free survival in the SVR group. RESULTS: Post-hepatectomy overall and recurrence-free survival rates were significantly higher in the SVR group than the non-SVR group (P < 0.01 and <0.05, respectively). Univariate analysis of post-hepatectomy recurrence-free survival in the SVR group revealed multiple significant factors: aspartate aminotransferase, 25 IU/L or more (P = 0.01); indocyanine green retention rate at 15 min, 20.0% or less (P < 0.05); hepatic vascular invasion (P < 0.05); and an interval of months or less between achieving a SVR and hepatectomy (P < 0.01). Multivariate analysis confirmed an interval of 30 months or less between achieving a SVR and hepatectomy as an independent prognostic factor of recurrence-free survival (hazard ratio, 2.30; 95.0% confidence interval, 1.04-5.13; P < 0.05). CONCLUSION: The interval between achieving a SVR and hepatectomy is an important predictor of recurrence in hepatitis C virus infection-related HCC patients who achieved a SVR.

Influence of higher BMI for hepatitis B- and C-related hepatocellular carcinomas.

PURPOSE: Although obesity is associated with hepatocellular carcinoma (HCC) development, its impact on the surgical outcomes of patients with hepatitis B virus (HBV)-and hepatitis C virus (HCV)-related HCC remains unclear. METHODS: We retrospectively analyzed 714 patients with HCC who underwent curative hepatectomy. Among them, the HBV-related HCC group (n = 125) and HCV-related HCC group (n = 426) were subdivided according to the presence of body mass index (BMI) ≥ 25 kg/m2. The surgical outcomes were compared. RESULTS: The 5-year overall survival rate after hepatectomy in the HBV-related HCC group was significantly better than that in the HCV-related HCC group. The 5-year overall survival rates of the HBV-related HCC with and without BMI ≥ 25 kg/m2 groups were 65 and 85%, respectively. The 5-year overall survival rates in the HCV-related HCC with and without BMI ≥ 25 kg/m2 groups were 75 and 65%, respectively. The HBV-related HCC with BMI ≥ 25 kg/m2 groups had a significantly worse prognosis than the HBV-related HCC without BMI ≥ 25 kg/m2 groups, while the HCV-related HCC with BMI ≥ 25 kg/m2 groups had a significantly better prognosis than the HCV-related HCC without BMI ≥ 25 kg/m2 groups. Multivariate analysis revealed that BMI ≥ 25 kg/m2 was the positive and negative prognostic factor for the surgical outcomes of patients with HBV- and HCV-related HCC, respectively. CONCLUSIONS: BMI ≥ 25 kg/m2 negatively affected the surgical outcomes of patients with HBV-related HCC and positively affected those of patients with HCV-related HCC.

Surgical outcomes of patients with acute cholecystitis treated with gallbladder drainage followed by early cholecystectomy.

AIM: This study aimed to investigate the impact of preoperative gallbladder drainage and the specific drainage method used on surgical outcomes in patients undergoing surgery for acute cholecystitis. METHODS: This single-center retrospective cohort study included 221 patients who underwent early cholecystectomy between January 2016 and December 2020. Clinical data and outcomes of 140 patients who did not undergo drainage, 22 patients who underwent preoperative percutaneous transhepatic gallbladder drainage (PTGBD), and 59 patients who underwent preoperative endoscopic naso-gallbladder drainage (ENGBD) were compared. RESULTS: There was no difference in the operation time, blood loss, postoperative complications, or length of postoperative hospital stay between patients who did and did not undergo drainage. Among patients who underwent drainage, there was no difference between the ENGBD and PTGBD groups in operation time, blood loss, or postoperative complications; however, more patients in the PTGBD group underwent laparotomy and had a significantly longer postoperative hospital stay. The presence and type of drainage were not risk factors for postoperative complications. CONCLUSION: The presence or absence of preoperative gallbladder drainage for acute cholecystitis and the type of drainage may not significantly affect surgical outcomes.

Peritoneal dissemination of appendiceal goblet cell adenocarcinoma mimicking white pus caused by peritonitis following appendicitis: an instructive case report.

BACKGROUND: Goblet cell adenocarcinoma is an extremely rare tumor in which the same cells exhibit both mucinous and neuroendocrine differentiation. It is considered more aggressive compared to conventional carcinoids and more likely to cause metastasis. CASE PRESENTATION: We report a case of goblet cell adenocarcinoma with peritoneal metastases. A 62-year-old man underwent appendectomy for acute appendicitis. Intraoperatively, inflammatory white pus and a small amount of dirty ascites were observed in the lower abdomen with severely inflamed appendix. Histopathological examination of the specimen collected during appendectomy revealed goblet cell adenocarcinoma with a positive surgical margin. One month later, additional ileal resection was planned. Laparoscopic examination revealed disseminated nodules throughout the abdominal cavity. Therefore, the patient underwent resection of the peritoneal nodules. The peritoneal specimens confirmed the histopathological findings. Thus we diagnosed the patient with peritoneal dissemination of appendiceal goblet cell adenocarcinoma. CONCLUSIONS: In cases wherein white pus is observed during surgery for acute appendicitis, considering the possibility of dissemination, collecting samples for histopathological examination, and initiating early treatment are crucial.

Preoperative diagnosis and safe surgical approach in gallbladder amyloidosis: a case report.

BACKGROUND: Preoperative diagnosis of gallbladder amyloidosis is usually difficult. In our case, the patient exhibited gallbladder dyskinesia, which led us to suspect cholecystic amyloidosis. We were able to safely perform surgery before cholecystitis onset. CASE PRESENTATION: A 59-year-old male patient with a history of multiple myeloma and cardiac amyloidosis presented to our hospital with a chief complaint of epicardial pain. Abdominal ultrasonography and computed tomography revealed an enlarged gallbladder and biliary sludge without any specific imaging findings of cholecystitis. After percutaneous transhepatic gallbladder aspiration (PTGBA), the patient experienced recurrent bile retention and right upper quadrant pain. Flopropione was effective in relieving these symptoms. Based on his symptoms and laboratory findings, we diagnosed the patient with dyskinesia of the gallbladder. Considering his medical history, we suspected that it was caused by amyloidosis of the gallbladder. A laparoscopic cholecystectomy was performed. The histopathological examination showed amyloid deposits in the gallbladder mucosa, from the intrinsic layer to the submucosa, and in the peripheral nerves of the gallbladder neck. The patient was discharged on postoperative day 5 and has had no recurrence of abdominal pain since then. CONCLUSION: In our case, gallbladder dyskinesia symptoms led us to suspect gallbladder amyloidosis. We safely surgically treated the patient before cholecystitis onset.

Evaluation of prognostic efficacy of liver immune status index in predicting postoperative outcomes in hepatocellular carcinoma patients: A multi-institutional retrospective study.

BACKGROUND: Hepatocellular carcinoma (HCC) ranks third in cancer-related deaths globally. Despite treatment advances, high post-hepatectomy recurrence rates (RR), especially with liver fibrosis and hepatitis C virus infection, remain challenging. Key prognostic factors include vascular invasion and perioperative blood loss, impacting extrahepatic recurrence. Natural killer (NK) cells are crucial in countering circulating tumor cells through TRAIL-mediated pathways. The aim of this study was to validate the liver immune status index (LISI) as a predictive tool for liver NK cell antitumor efficiency, particularly in HCC patients with vascular invasion. METHODS: A retrospective analysis of 1337 primary HCC hepatectomies was conducted by the Hiroshima Surgical Study Group of Clinical Oncology (HiSCO). Clinicodemographic data were extracted from electronic medical records. Prognostic indices (FIB-4, ALBI, ALICE, GNRI, APRI, and LISI) were evaluated using area under the receiver operating characteristic curve values. Survival analyses employed Kaplan-Meier estimations and log-rank tests. RESULTS: LISI significantly correlated with other prognostic markers and stratified patients into risk groups with distinct overall survival (OS) and RR. It showed superior predictive performance for 2-year OS and RR, especially in patients with vascular invasion. Over longer periods, APRI and FIB-4 index reliabilities improved. The HISCO-HCC score, combining LISI, tumor burden score, and alpha-fetoprotein levels, enhanced prognostic accuracy. CONCLUSION: LISI outperformed existing models, particularly in HCC with vascular invasion. The HISCO-HCC score offers improved prognostic precision, guiding immunotherapeutic strategies and individualized patient care in HCC.

Impact of Geriatric Nutritional Risk Index After Initial Hepatectomy for Hepatocellular Carcinoma: a Retrospective Cohort Study with the Hiroshima Surgical Study Group of Clinical Oncology (HiSCO).

INTRODUCTION: The importance of a nutrition scoring system, including the geriatric nutritional risk index (GNRI), was reported as an objective tool widely used to assess nutritional status in patients with inflammatory disease, chronic heart failure, and chronic liver disease. However, studies on the relationship between GNRI and the prognosis in patients who have undergone initial hepatectomy have been limited. Thus, we conducted a multi-institutional cohort study to clarify the relationship between GNRI and long-term outcomes for hepatocellular carcinoma (HCC) patients after such a procedure. METHODS: Data from 1,494 patients who underwent initial hepatectomy for HCC between 2009 and 2018 was retrospectively collected from a multi-institutional database. The patients were divided into two groups according to GNRI grade (cutoff: 92), and their clinicopathological characteristics and long-term results were compared. RESULTS: Of the 1,494 patients, the low-risk group (≥ 92; N = 1,270) was defined as having a normal nutritional status. Meanwhile, low GNRI (< 92; N = 224) were divided into malnutrition as the high-risk group. Multivariate analysis identified seven prognostic factors of poor overall survival (higher tumor markers; α-fetoprotein (AFP) and des-γ-carboxy protein [DCP], higher ICG-R15 levels, larger tumor size, multiple tumors, vascular invasion, and lower GNRI and eight prognostic factors of high recurrence (HCV antibody positive, higher ICG-R15 levels, higher tumor markers such as AFP and DCP, greater bleeding, multiple tumors, vascular invasion, and lower GNRI). CONCLUSIONS: In patients with HCC, preoperative GNRI predicts poorer overall survival and high recurrence.

Risk Factors for Hepatocellular Carcinoma After Splenectomy in Liver Cirrhotic Patients.

BACKGROUND: Splenectomy is sometimes indicated for portal hypertension caused by cirrhosis, which is a risk for hepatic carcinogenesis. This study aimed to identify risk factors for hepatocellular carcinoma (HCC) development after splenectomy. METHODS: This retrospective study included 65 patients who underwent splenectomy for portal hypertension between 2009 and 2017. Cox regression analyses were performed to identify factors related to HCC development after splenectomy. The predictive index for HCC development was constructed from the results of multivariate analysis, and 3 risk-dependent groups were defined. Discrimination among the groups was estimated using Kaplan-Meier curves and the log-rank test. RESULTS: Post-splenectomy, 36.9% of patients developed HCC. In the univariate analysis, the etiology of cirrhosis (hepatitis C virus antibody, P = .005, and hepatitis B surface antigen, P = .008, referring to non-B and non-C patients, respectively), presence of HCC history (P < .001), and preoperative hemoglobin level (P = .007) were related to HCC development, and the presence of HCC history (P = .002) and preoperative hemoglobin level (P = .022) were independent risk factors. The predictive index classified three groups at risk; the hazards in each group were significantly different (low vs middle risk, P = .035, and middle vs high risk, P = .011). DISCUSSION: The etiology of cirrhosis, presence of HCC history, and hemoglobin level were associated with HCC development after splenectomy. The predictive model may aid in HCC surveillance after splenectomy for patients with portal hypertension.

Superior mesenteric vein to the right testicular vein shunt operation for jejunal varices bleeding associated with extrahepatic portal vein obstruction after pancreaticoduodenectomy: a case report.

BACKGROUND: Causes of extrahepatic portal vein obstruction include abdominal surgeries such as pancreaticoduodenectomy. We improved jejunal variceal bleeding due to extrahepatic portal vein occlusion after pancreaticoduodenectomy, by shunting of the testicular vein. CASE PRESENTATION: A 72-year-old man was diagnosed with extrahepatic bile duct cancer and underwent subtotal stomach-preserving pancreaticoduodenectomy 5 years ago. No postoperative complications occurred, adjuvant chemotherapy using gemcitabine hydrochloride was performed, and the patient remained recurrence-free. One year and 6 months post-operation, extrahepatic portal vein stenosis appeared, but no recurrence was noted. However, 4 years and 6 months later, recurrent gastrointestinal bleeding occurred, and the patient was diagnosed with an extrahepatic portal vein obstruction. Double-balloon enteroscopy showed capillary dilatation and varicose veins in the hepaticojejunostomy region, and venous bleeding from collateral blood vessels was diagnosed. A superior mesenteric vein to the right testicular vein shunt operation was performed, following which the gastrointestinal bleeding disappeared, and the anemia improved. Although transient hepatic encephalopathy occurred, conservative treatment relieved it. Double-balloon enteroscopy confirmed the disappearance of abnormal blood vessels. CONCLUSIONS: A portosystemic shunt operation using the right testicular vein effectively relieved refractory variceal bleeding around the hepaticojejunostomy site in the jejunum due to an extrahepatic portal vein obstruction after pancreaticoduodenectomy.

Comparison of Three Clinical Trials of Preoperative Predictors for Complicated Appendicitis.

BACKGROUND/AIM: We previously reported three items that preoperatively predicted complicated appendicitis (body temperature, C-reactive protein, and fluid retention around the appendix). In this study, we aimed to compare other predictors to confirm the usefulness of our predictors with those of previous reports on the items as predictors of complicated appendicitis preoperatively (criteria A which consist of 8 items, criteria B which consist of 7 items). PATIENTS AND METHODS: We retrospectively evaluated 417 adult patients who underwent surgery for acute appendicitis between January 2013 and December 2019 and compared our items with criteria A and criteria B according to the results of the area under the receiver operating characteristic curve (AUC), homogeneity, discriminatory ability, and Akaike information criterion (AIC). RESULTS: The AUC for the sensitivity to diagnose complicated appendicitis according to according to our criteria, as well as criteria A, and criteria B was 0.823, 0.839, and 0.856, respectively. The discriminatory ability linear trend χ2 of our criteria and those of criteria A and B were 128.9, 121.1, and 142.5, respectively. The homogeneity likelihood ratios χ2 calculated using the Cox regression model, which indicate homogeneity, were 146.4, 143.6, and 172.8, respectively. The AIC of each criterion was 397.0, 345.8, and 369.0, respectively. CONCLUSION: Although the criteria B were the best, it was possible to predict complicated appendicitis preoperatively by all criteria. Above all, our criteria have only three items, therefore they have the advantage of making it possible to make decisions quickly with a certain degree of accuracy, regardless of the degree of experience.

Mixed neuroendocrine non-neuroendocrine neoplasm: a case report and review.

Mixed neuroendocrine non-neuroendocrine neoplasm (MiNEN) of the pancreas is a rare entity, and obtaining a preoperative diagnosis is difficult. We present a 70-year-old man in whom the possibility of MiNEN was successfully discovered preoperatively by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). Immunostaining revealed positive results for the neuroendocrine markers chromogranin A and synaptophysin. We considered the possibility for MiNEN before surgery. He underwent distal pancreatectomy with splenectomy. Immunohistochemical examination of the tumor cells showed a wide range of positivity for trypsin as well as for chromogranin A and synaptophysin. Considering that ≥ 30% tumors ware positive for both acinar and neuroendocrine markers, the patient was diagnosed with MiNEN. MiNEN is a malignant tumor that requires early detection and treatment but is a rare disease for which no method has been established. We found that EUS-FNA and immunostaining are effective diagnostic methods for MiNEN.

Perforation of the descending colon diverticulum in a patient following recovery from severe COVID-19 pneumonia: a case report.

The outcome of surgery in patients who have recovered from severe coronavirus disease 2019 (COVID-19) is unknown. Herein, we present a case of an emergency operation for acute pan-peritonitis due to perforation of the descending colon diverticulum in a patient who recovered from severe COVID-19 pneumonia. A 59-year-old man, who had recovered from severe COVID-19 pneumonia ~6 months previously, developed acute pan-peritonitis due to perforation of a diverticulum in the descending colon. Emergency surgery was performed, and the perforation was sutured and closed. He was discharged from the hospital 13 days postoperatively. There was no relapse of COVID-19 during the perioperative period of peritonitis surgery. General perioperative management may, therefore, be sufficient in patients who have recovered from COVID-19.

Management of acute cholecystitis in patient with cyclic neutropenia: a case report.

BACKGROUND: Cyclic neutropenia is a disease that causes a neutropenic decrease in peripheral blood in a cycle of about 21 days. It is a rare hereditary disorder with an estimated incidence of 0.5-1 cases per million population. The absolute neutrophil count can drop to zero, and neutropenic nadir may last for 3-5 days. This is a rare disease, and there are few reports of abdominal surgery in cyclic neutropenia patients; thus, we report this case of neutrophil count fluctuation and perioperative management. CASE PRESENTATION: A 31-year-old man with cyclic neutropenia was transferred to our hospital complaining of right season rib pain, but no rebound tenderness. His C-reactive protein was elevated (4.37 mg/L) and computed tomography revealed a large number of small stones in the gallbladder body and an incarceration in the gallbladder neck. He was diagnosed with acute cholecystitis. Ideally, surgical intervention should have been performed immediately, but because his neutrophil count was 300/µL, endoscopic naso-gallbladder drainage was performed and he was provided antibiotics until his neutrophil count increased to acceptable levels. Three days after admission, his neutrophil count had increased and laparoscopic cholecystectomy was performed. For one week after the operation, antibiotics were administered; he had an uneventful postoperative recovery. He was discharged on the seventh postoperative day and provided an oral antibiotic. CONCLUSIONS: Infection can be serious in patients with cyclic neutropenia, and it is therefore, important to determine the timing of surgery and to apply appropriate perioperative management with drainage and antibiotic administration.

A lymphoepithelial cyst in the pancreatic accessory spleen: A case report.

We present the first report of a lymphoepithelial cyst. As additional cases will likely be encountered in the future, our study sets the precedent for future research.

Intussusception caused by small intestine metastasis of malignant pleural mesothelioma: a case report.

Malignant pleural mesothelioma (MPM) is an aggressive form of malignant tumor that originates in the pleural mesothelioma and presents as a local disease in the affected hemithorax. Small intestine metastasis is a rare complication. Herein, the case of a patient with jejunal intussusception caused by small intestine metastasis of MPM has been reported. A 72-year-old man with MPM was admitted to our hospital for abdominal pain. Computed tomography revealed small intestine intussusception. An emergency surgery was performed, and the tumor and intussusception were located in the upper jejunum. Histopathological examination of the resected jejunum revealed that the tumor was a small intestinal metastasis of the MPM from the chest wall. This case showed that MPM may metastasize to the small intestine, and metastatic tumors may cause intussusception.

Impact of postoperative bile leakage on long-term outcome in patients following liver resection for hepatocellular carcinoma.

BACKGROUND/PURPOSE: The incidence of bile leakage after liver resection for hepatocellular carcinoma (HCC) remains a cause for concern. There are limited reports on the impacts of postoperative bile leakage on long-term clinical outcomes. This study aims to evaluate the effects of postoperative bile leakage on recurrence-free survival (RFS) and overall survival (OS). METHODS: A total of 1,178 patients who underwent curative liver resection for HCC between 1986 and 2012 were included in the present study. Postoperative bile leakage was defined using the International Study Group of Liver Surgery definition, and the primary end points of the study were OS and RFS at 5 years. RESULTS: Forty-three (3.7%) patients had bile leakage following liver resection. The median follow-up was 5 years. A follow-up analysis revealed that patients with bile leakage had poor 5-year rates of OS (41.0% vs 56.4%, P = .013) and RFS (14.6% vs 28.7%, P < .001). Additionally, bile leakage was an independent factor for both OS [hazard ratio (HR) 1.559, P = .022] and RFS (HR 1.517, P = .024). Furthermore, bile leakage was the only factor affecting prognosis among postoperative complications. CONCLUSIONS: Postoperative bile leakage worsens long-term clinical outcomes following liver resection in HCC patients.
