Development of predictive score for postoperative dysphagia after emergency abdominal surgery in patients of advanced age.

Aim: Postoperative dysphagia after emergency abdominal surgery (EAS) in patients of advanced age has become problematic, and appropriate dysphagia management is needed. This study was performed to identify predictive factors of dysphagia after EAS and to explore the usefulness of swallowing screening tools (SSTs). Methods: This retrospective study included 267 patients of advanced age who underwent EAS from 2012 to 2022. They were assigned to a dysphagia group and non-dysphagia group using the Food Intake Level Scale (FILS) (dysphagia was defined as a FILS level of <7 on postoperative day 10). From 2018, original SSTs including a modified water swallowing test were performed by nurses. Results: The incidence of postoperative dysphagia was 22.8% (61/267). Patients were significantly older in the dysphagia than non-dysphagia group. The proportions of patients who had poor nutrition, cerebrovascular disorder, Parkinson's disease, dementia, nursing-care service, high intramuscular adipose tissue content (IMAC), and postoperative ventilator management were much higher in the dysphagia than non-dysphagia group. Using logistic regression analysis, high IMAC, postoperative ventilator management, cerebrovascular disorder, and dementia were correlated with postoperative dysphagia and were assigned 10, 4, 3, and 3 points, respectively, according to each odds ratio. The optimal cut-off value was 7 according to a receiver operating characteristics curve. Using 1:1 propensity score matching for high-risk patients, the incidence of postoperative dysphagia was reduced by SSTs. Conclusions: The new prediction score obtained from this study can identify older patients at high risk for dysphagia after EAS, and SSTs may improve these patients' short-term outcomes.

[A 30-Month Survival Case of Undifferentiated Carcinoma of the Duodenum Treated by Pancreaticoduodenectomy].

The patient was an elderly man in his early 80s who was admitted to our hospital due to anemia and tarry stools. An upper gastrointestinal endoscopy revealed a type 2 tumor in the second portion of the duodenum. An endoscopic biopsy revealed poorly differentiated adenocarcinoma. We performed a pancreaticoduodenectomy because neither lymphadenopathy nor distant metastases were found. Macroscopic findings revealed that the lesion was mainly in the second portion of the duodenum, and there was no evidence of invasion of the main pancreatic duct, the bile duct, or the ampulla of Vater. Histologically, the tumor was composed of atypical cells with polymorphic or spindle-shaped nuclei proliferating in a scattered fashion, and immunohistological examinations showed weakly positive results for cytokeratin(CK)AE1/AE3 and CK20 and positive results for vimentin but negative results for CK7. The tumor was diagnosed as undifferentiated carcinoma of the duodenum(pT4N0M0, pStage ⅡB). The patient recovered enough to be discharged and was followed up without postoperative adjuvant chemotherapy. He maintained recurrence-free survival for 27 months, after which lymph node and lung metastases reoccurred. This is a rare case of undifferentiated carcinoma of the duodenum treated by curative resection with a relatively favorable prognosis.

Textbook outcome in the laparoscopic cholecystectomy of acute cholecystitis.

PURPOSE: Textbook outcome (TO) is a novel composite measure of clinical outcomes that can be used to measure the quality of surgical outcomes. The aim of this cohort study was to propose TO criteria for laparoscopic cholecystectomy for acute cholecystitis and to identify reasons for TO failure and individual patient factors that predispose to failure. METHODS: We retrospectively analyzed data for 189 patients with acute cholecystitis who underwent laparoscopic cholecystectomy. TO was defined as laparoscopic cholecystectomy without conversion to open cholecystectomy, intraoperative complications, postoperative complications (Clavien-Dindo classification ≥2), prolonged length of stay (≥10 days), readmission within 30 days, or mortality. RESULTS: TO was achieved in 154 of 189 patients who underwent laparoscopic cholecystectomy for acute cholecystitis. Medical costs were lower in the TO-achieved group than in the TO-failure group. Factors associated with TO failure on multivariate analysis were age > 70 years, hemoglobin <11.9 g/dL, and white blood cells >18 000 / µL (all P < .05). CONCLUSIONS: Applying TO to patients with acute cholecystitis allowed us to evaluate the overall quality of care related to hospitalization. TO may provide better assessment of the quality of care and help determine the treatment choice and reduce costs.

Safety of laparoscopic cholecystectomy in patients with a cerebrospinal fluid shunt in the peritoneal cavity.

INTRODUCTION: The management of patients with a cerebrospinal fluid (CSF) shunt located in the peritoneal cavity undergoing laparoscopic surgery is an issue that has not yet been settled. These patients are at risk of increased intracranial pressure caused by peritoneal insufflation, shunt dysfunction, and shunt infection/retrograde meningitis. This study aimed to determine the need for perioperative shunt intervention in CSF shunt patients undergoing laparoscopic cholecystectomy. METHODS: We reviewed and analyzed five shunt patients who underwent laparoscopic cholecystectomy in our institution between 2012 and 2022, as well as 17 patients described in previous reports. RESULTS: Among the 22 patients, shunt type was ventriculoperitoneal in 14 and lumboperitoneal in eight. The most common indication for CSF shunt was hydrocephalus caused by cerebral vascular accident (50.0%). Laparoscopic cholecystectomy was performed for cholecystolithiasis in 13 patients (59.1%), acute cholecystitis in eight (36.4%), and gallbladder polyp in one (4.5%). Shunt clamping or externalization was performed in six patients. Two patients in the group that did not undergo shunt clamping or externalization experienced complications (intra abdominal abscess and subcutaneous emphysema). However, the incidence of short-term complications (both overall and shunt-related) and median length of hospital stay did not significantly differ between the two groups. CONCLUSION: Routine shunt clamping, externalization, or removal might not be necessarily required in patients with a ventriculoperitoneal or lumboperitoneal shunt undergoing laparoscopic cholecystectomy.

Successful laparoscopic cholecystectomy for gallbladder hemorrhage from a Dieulafoy lesion in a patient on hemodialysis: a case report.

BACKGROUND: Patients on long-term dialysis are prone to hemorrhagic complications, particularly uremic bleeding, but gallbladder hemorrhage is rare, even in patients on dialysis. There have been occasional reports of a Dieulafoy lesion being a cause of gastrointestinal hemorrhage, but its occurrence within the gallbladder is quite rare. This report describes a case of gallbladder hemorrhage from a Dieulafoy lesion in a patient on hemodialysis that was diagnosed early and successfully treated by laparoscopic cholecystectomy. CASE PRESENTATION: The patient was a 68-year-old woman on long-term hemodialysis with end-stage renal failure who presented with epigastralgia and back pain. There was no history of trauma or oral administration of antiplatelet or anticoagulant agents. There were no signs of an inflammatory reaction or hyperbilirubinemia. Contrast-enhanced computed tomography revealed a slightly hyperdense area in the distended gallbladder and extravasation within the gallbladder lumen but no gallstones. A severe atherosclerotic lesion was also found. She was diagnosed to have gallbladder hemorrhage and emergency laparoscopic cholecystectomy was performed. Although the postoperative course was complicated by drug fever, she was discharged on postoperative day 10 in a satisfactory condition. Histology revealed hemorrhagic ulceration with an exposed blood vessel accompanied by abnormal arteries in the submucosa. Arteriosclerosis with eccentric intimal hyperplasia in a small-sized artery was also seen. The diagnosis was gallbladder hemorrhage from a Dieulafoy lesion. CONCLUSIONS: A Dieulafoy lesion should be kept in mind as a cause of gallbladder hemorrhage in a patient with severe arteriosclerosis and a bleeding diathesis, particularly if on dialysis, and treated as early as possible.

Prognostic Impact of Lymphocyte-to-C-Reactive Protein Ratio in Patients Who Underwent Surgical Resection for Pancreatic Cancer.

BACKGROUND: Increasing evidence indicates that increased systemic inflammation is correlated with poorer cancer-specific survival in various cancer types. This study aimed to evaluate the prognostic value of various combinations of inflammatory factors in patients who underwent surgical resection for pancreatic cancer (PC). METHODS: We retrospectively analyzed 97 consecutive patients with PC who underwent pancreatectomy. We assessed the predictive impact for recurrence using a combination of 5 inflammatory markers and focused on the lymphocyte-C-reactive protein ratio (LCR) to elucidate its prognostic and predictive value for recurrence-free survival (RFS) and overall survival (OS) in univariate and multivariate analyses using the Cox proportional hazards model. RESULTS: Low preoperative LCR was correlated with low serum hemoglobin, low serum albumin concentration, high frequency of microscopic vascular invasion, and high frequency of microscopic perineural invasion. The low LCR group had significantly worse RFS and OS. Lower preoperative LCR was an independent predictor of shorter RFS and OS in this cohort. DISCUSSION: Preoperative LCR is a novel and convenient prognostic marker for patients with PC. Patients with low LCR may require more favorable intensive therapy.

Prognostic Impact of the Preoperative Systemic Inflammation Score in Patients With Pancreatic Ductal Adenocarcinoma.

BACKGROUD: The systemic inflammation score (SIS), which is based on the preoperative lymphocyte-to-monocyte ratio (LMR) and serum albumin (Alb) level, is a prognostic indicator for several cancer types. However, the prognostic significance of the SIS in pancreatic ductal adenocarcinoma (PDAC) remains unknown. METHODS: Seventy-eight patients who underwent radical surgery for PDAC were categorized as follows: SIS 0 (LMR ≥3.51 and Alb ≥4.0 g/dl), n = 26; SIS 1 (LMR <3.51 or Alb <4.0 g/dl), n = 29 and SIS 2 (LMR <3.51 and Alb <4.0 g/dl), n=23. RESULTS: The tumour size sequentially increased in SIS 0, 1 and 2 groups. A higher SIS was associated with increased vascular invasion, perineural invasion and surgical margin positivity rate. Recurrence-free survival (RFS) rates between the SIS 1 and 2 groups showed no significant difference However, patients of the SIS 1 and 2 groups had poorer outcomes than those of the SIS 0 group for RFS. Overall survival (OS) rates between the SIS 1 and 2 groups also showed no significant difference. However, patients of the SIS 1 and 2 groups had poorer outcomes than those of the SIS 0 group for OS. The SIS was an independent prognostic factor for RFS and OS. DISCUSSION: The SIS is a simplified prognostic factor for patients with PDAC.

Delayed laparoscopic cholecystectomy for a patient with coronavirus disease 2019 who developed gangrenous cholecystitis: a case report.

BACKGROUND: Gangrenous cholecystitis has a high risk of perforation and sepsis; therefore, cholecystectomy in the early stage of the disease is recommended. However, during the novel coronavirus disease 2019 (COVID-19) pandemic, the management of emergent surgeries changed to avoid contagion exposure among medical workers and poor postoperative outcomes. CASE PRESENTATION: A 56-year-old man presented to our hospital with abdominal pain. Computed tomography revealed intraluminal membranes, an irregular or absent wall, and an abscess of the gallbladder, indicating acute gangrenous cholecystitis. Early laparoscopic cholecystectomy seemed to be indicated; however, a COVID-19 antigen test was positive despite no obvious pneumonia on chest computed tomography and no symptoms. After discussion among the multidisciplinary team, antibiotic therapy was started and percutaneous transhepatic gallbladder drainage (PTGBD) was planned for the following day because the patient's vital signs were stable and his abdominal pain was localized. Fortunately, the antibiotic therapy was very effective, and PTGBD was not needed. The cholecystitis improved and the patient was discharged from the hospital on day 10. One month later, laparoscopic delayed cholecystectomy was performed after confirming a negative COVID-19 polymerase chain reaction test result. The postoperative course was uneventful, and the patient was discharged on postoperative day 2 in satisfactory condition. CONCLUSION: We have reported a case of acute gangrenous cholecystitis in a patient with asymptomatic COVID-19 disease. This report can help to determine treatment strategies for patients with gangrenous cholecystitis during future pandemics.

A case of successful conversion surgery for locally advanced pancreatic cancer with synchronous triple cancer of the lung and esophagus: a case report.

BACKGROUND: The number of reports of multiple primary cancer (MPC) is increasing because of the advancement in diagnostic imaging technology. However, the treatment strategy for MPCs involving pancreatic cancer is controversial because of the extremely poor prognosis. We herein report a patient with synchronous triple cancer involving the pancreas, esophagus, and lung who underwent conversion surgery after intensive chemotherapy for unresectable locally advanced pancreatic cancer. CASE PRESENTATION: A 59-year-old man was admitted to our hospital with epigastric pain, anorexia, and weight loss. Computed tomography and upper gastrointestinal endoscopy revealed that the patient had synchronous triple cancer of the pancreas, esophagus, and lung. While the esophageal and lung cancer were relatively non-progressive, the pancreatic tail cancer had invaded the aorta, celiac axis, and left kidney, and the patient was diagnosed with unresectable locally advanced disease. Because the described lesion could have been the prognostic determinant for this patient, we initiated intensive chemotherapy (gemcitabine plus nab-paclitaxel) for pancreatic cancer. After six courses of chemotherapy, the tumor size shrank remarkably and no invasion to the aorta or celiac axis was observed. No significant changes were observed in the esophageal and lung cancers; endoscopic submucosal dissection could be still a curative treatment for the esophageal cancer. Therefore, we performed curative resection for pancreatic cancer (distal pancreatomy, splenectomy, and left nephrectomy; ypT3N0cM0, ypStage IIA, UICC 8th). Pathologically, complete resection was achieved. The patient then underwent endoscopic submucosal dissection for early esophageal cancer (pT1a[M]-LPM) and video-assisted thoracoscopic right upper lobectomy in combination with right lower partial resection for early lung cancer (pT2aN0M0, pStage IB, UICC 8th). Eight months after pancreatic cancer surgery, the patient is alive and has no sign of recurrence; as a result of the successful treatment, the patient has a good quality of life. CONCLUSIONS: Treatment of MPC is challenging, especially for cases with unresectable tumors. Although synchronous triple cancer can involve unresectable pancreatic cancer, radical resection may be possible after careful assessment of the appropriate treatment strategy and downstaging of unresectable tumors.

High Pretreatment Mean Corpuscular Volume Can Predict Worse Prognosis in Patients With Esophageal Squamous Cell Carcinoma who Have Undergone Curative Esophagectomy: A Retrospective Multicenter Cohort Study.

Objective: To establish the prognostic value of mean corpuscular volume (MCV) in patients with esophageal squamous cell carcinoma (ESCC) who have undergone esophagectomy. Background: The MCV increases in patients with high alcohol and tobacco consumption. Such a lifestyle can be a risk factor for malnutrition, comorbidities related to those habits, and multiple primary malignancies, which may be associated with frequent postoperative morbidity and poor prognosis. Methods: This study included 1673 patients with ESCC who underwent curative esophagectomy at eight institutes between April 2005 and November 2020. Patients were divided into normal and high MCV groups according to the standard value of their pretreatment MCV. Clinical background, short-term outcomes, and prognosis were retrospectively compared between the groups. Results: Overall, 26.9% of patients had a high MCV, which was significantly associated with male sex, habitual smoking and drinking, multiple primary malignancies, and malnutrition, as estimated by the body mass index, hemoglobin and serum albumin values, and the Geriatric Nutritional Risk Index. Postoperative respiratory morbidity (P = 0.0075) frequently occurred in the high MCV group. A high MCV was an independent prognostic factor for worse overall survival (hazard ratio, 1.27; 95% confidence interval, 1.049-1.533; P = 0.014) and relapse-free survival (hazard ratio, 1.23; 95% confidence interval, 1.047-1.455; P = 0.012). Conclusions: A high MCV correlates with habitual drinking and smoking, malnutrition, and multiple primary malignancies and could be a surrogate marker of worse short-term and long-term outcomes in patients with ESCC who undergo esophagectomy.

Novel case of laparoscopically resected gastric adenocarcinoma concurrent with lanthanum deposition.

A 73-year-old man taking lanthanum carbonate for hemodialysis showed progressing gastric mucosal changes with lanthanum deposition. Regular examination revealed concurrent gastric carcinoma. The extent and depth of its invasion were ambiguous because of the surrounding lanthanum deposition. Furthermore, there could be other potent carcinomas, and curative laparoscopic gastrectomy was performed.

An Adult Case of Multiple Extralobar Pulmonary Sequestrations in the Thoracic and Abdominal Cavities.

Extralobar pulmonary sequestration is generally located in the left thoracic cavity and is often identified prenatally or in infants. We identified a rare case of multiple extralobar pulmonary sequestrations in the thoracic and abdominal cavities, incidentally detected in a 60-year-old woman by cancer screening. The patient underwent surgery by thoracoscopic and laparoscopic approaches simultaneously, and extralobar sequestration was histologically confirmed in each lesion. Preoperative diagnosis was difficult because of unusual multiple localization and an undetectable aberrant artery on imaging examinations.

Laparoscopic delayed and interval appendectomy in the workstyle reform era.

PURPOSE: Excessive working hours have been reported to contribute to burnout among surgeons. In Japan, work-style reform is a problem that needs immediate attention. Acute appendectomy, which often occurs at nighttime, is one of the most common emergency surgeries. The feasibility of delayed and interval appendectomy remains to be investigated. METHODS: Two hundred forty-five consecutive patients who underwent laparoscopic appendectomy in our hospital were enrolled. They were divided into three groups: emergency appendectomy (immediate surgery, soon after the diagnosis [EA group], n = 153), delayed appendectomy (surgery during daytime the following day [DA group], n = 38) and interval appendectomy (antibiotics treatment followed by selective surgery three to four months later [IA group], n = 54). The clinical background and surgical outcomes were compared. Next, the residents' excess working time per month was calculated. RESULTS: The surgical outcomes (operation time, blood loss, length of hospital stay, postoperative complications) were similar between the EA and DA groups. However, no DA was performed during nighttime hours whereas 15.7% of EA was performed during nighttime hours (p = 0.0007). The surgical outcomes of the IA group were also comparable. The residents' excess working time declined following the introduction of DA and workstyle reform. CONCLUSION: Delayed and interval laparoscopic appendectomy are feasible, and can be performed to promote workstyle reform without impairing patient safety.

Indocyanine green fluorescence to ensure perfusion in middle segment-preserving pancreatectomy: a case report.

BACKGROUND: Middle segment-preserving pancreatectomy (MSPP) is an alternative to total pancreatectomy that allows for the preservation of the endocrine and exocrine functions of the pancreas. However, maintaining perfusion to the pancreatic remnant is of critical importance. We describe the first case to our knowledge in which indocyanine green (ICG) fluorescence was used to confirm perfusion to the pancreatic remnant during MSPP. CASE PRESENTATION: A 79-year-old man with diabetes mellitus was referred to our hospital for treatment of a pancreatic tumor. Computed tomography revealed a hypovascular mass in the uncus of the pancreas and dilatation of the main pancreatic duct, measuring 13 mm in the tail of the pancreas. He was diagnosed with cancer of the pancreatic uncus via endoscopic ultrasound and fine-needle aspiration revealed a mixed-type intraductal papillary mucinous neoplasm (IPMN), along with high-risk stigmata in the tail of the pancreas. We performed MSPP and the length of the pancreatic remnant was 4.6 cm. The dorsal pancreatic artery was preserved and perfusion to the pancreatic remnant was confirmed by ICG fluorescence. Histopathological examination showed a pancreatic ductal adenocarcinoma in the uncus (pT1cN1M0, pStage 2B) and IPMN in the tail of the pancreas. The postoperative course was complicated by a grade B pancreatic fistula, but this was successfully treated with conservative management. The patient was transferred to a hospital 33 days after surgery. Insulin administration was necessary, but C-peptide was detectable and blood glucose was relatively well-controlled. He did not exhibit any exocrine dysfunction when pancreatic enzyme supplementation was administered. CONCLUSION: ICG fluorescence can be used to evaluate perfusion to the pancreatic remnant during MSPP.

Impact of a 7.5-Fr Pancreatic Stent for Preventing Pancreatic Fistula after Pancreaticoduodenectomy.

INTRODUCTION: Pancreatic duct stents are widely used to reduce the incidence of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD); however, small stents may cause adverse effects, such as occlusion. Recently, we have tried placing a 7.5-Fr pancreatic duct stent to achieve more effective exocrine output from the pancreas; however, the association between pancreatic duct stent size and POPF remains unknown. METHODS: Sixty-five patients with soft pancreatic texture who underwent PD were retrospectively analyzed. After dividing the pancreas, a pancreatic duct stent (stent size 4.0 in 29 patients, 5.0 in 18, and 7.5 Fr in 18) was placed in the main pancreatic duct. RESULTS: Twenty-five of 65 patients with soft pancreatic texture (38.5%) developed POPF. POPF became less frequent as the pancreatic duct stent size increased (p = 0.003). The factors associated with POPF development were a 7.5-Fr pancreatic duct stent (p = 0.005), 5.0-Fr pancreatic duct stent (p = 0.031), and male sex (p = 0.008). Pancreatic duct stent size and pancreatic duct diameter did not differ between the POPF and non-POPF groups. DISCUSSION/CONCLUSIONS: In patients with a soft pancreas, the placement of a 7.5-Fr pancreatic duct stent may reduce the incidence of POPF.

Impact of Osteopenia on Oncologic Outcomes After Curative Resection for Pancreatic Cancer.

BACKGROUND/AIM: We evaluated the relationship between low bone mineral density (BMD), also called osteopenia, and prognosis in patients who underwent resection for pancreatic cancer (PC). PATIENTS AND METHODS: We enrolled 91 consecutive patients who underwent curative resections for PC between May 2009 and January 2019. Their BMDs were measured at the Th11 vertebra using computed tomography. Patients were then divided by age-adjusted standard BMD values into the osteopenia group (n=34) and the non-osteopenia group (n=57). Their overall survival (OS) and recurrence-free survival (RFS) were compared (log-rank test). RESULTS: The two groups did not differ in age, BMI, tumor marker, operation time, blood loss, postoperative complications or stage. The osteopenia group had significantly worse 3-year rates for OS (46% vs. 30%, p=0.04) and RFS (41% vs. 26%, p=0.01). In multivariate analysis, osteopenia was an independent prognostic factor for RFS (HR=2.16, p=0.01). CONCLUSION: Osteopenia is an adverse prognostic factor for patients with resected PC.

Esophageal Position Affects Short-Term Outcomes After Minimally Invasive Esophagectomy: A Retrospective Multicenter Study.

BACKGROUND: Anatomical esophageal position may affect the short-term outcomes after minimally invasive esophagectomy (MIE). A previous single-institutional retrospective study suggested that the presence of a left-sided esophagus (LSE) made MIE more difficult and increased the incidence of postoperative complications. METHODS: The current study was a multicenter retrospective study of 303 patients with esophageal cancer who underwent MIE at six esophageal cancer high-volume centers in Kyushu, Japan, between April 2011 and August 2016. The patients were divided into the LSE (66 patients) and non-LSE groups (237 patients) based on the esophageal position on computed tomography images obtained with the patients in the supine position. RESULTS: Univariate analysis showed that patients with LSE were significantly older than those with non-LSE (69 ± 8 vs. 65 ± 9 years; P = 0.002), had a significantly greater incidence of cardiovascular comorbidity (65.2% vs. 47.7%; P = 0.013), and a significantly longer operating time (612 ± 112 vs. 579 ± 102 min; P = 0.025). Logistic regression analysis verified that LSE was an independent risk factor for the incidence of pneumonia (odds ratio 3.3, 95% confidence interval 1.254-8.695; P = 0.016). CONCLUSIONS: The presence of a LSE can increase the procedural difficulty of MIE and the incidence of morbidity after MIE. Thus, careful attention must be paid to anatomical esophageal position before performing MIE.

Refractory cutaneo-gastric conduit fistula after esophagectomy repaired by a pectoralis major muscle flap and split-thickness skin graft.

BACKGROUND: Gastric conduit ulcer after esophagectomy is not uncommon. In cases where a gastric conduit ulcer penetrates the adjacent organs, it is difficult to select a suitable treatment strategy. The treatment depends on the adjacent organs penetrated. CASE PRESENTATION: We report a case in which a reconstructed gastric conduit ulcer penetrated the precordial skin in a patient who had undergone esophagectomy due to spontaneous esophageal rupture 28 years previously. To treat the cutaneo-gastric conduit fistula, we resected the fistula, covered the site of anastomosis with a major pectoralis muscle flap, and applied a split-thickness skin graft to the skin defect. CONCLUSIONS: In cases of gastric conduit trouble in patients treated via the antesternal route, a major pectoralis muscle flap is useful because of its rich blood supply and easy mobilization. In addition, a split-thickness skin graft should be applied to the skin defect.

Alert Regarding Cisplatin-induced Severe Adverse Events in Cancer Patients with Xeroderma Pigmentosum.

Xeroderma pigmentosum (XP) is a genetic disease in which DNA repair mechanisms are impaired. Cisplatin (CDDP) exerts cytotoxic effects by forming mainly intrastrand DNA cross-links, and sensitivity to CDDP depends on the DNA repair system. Several in vitro studies have suggested that treatment with CDDP may cause enhanced adverse events as well as anti-tumor activity in cancer patients with XP. This article is the first to describe two cancer patients with XP showing severe adverse events following CDDP-based chemotherapy. Physicians should pay attention when administering CDDP in cancer patients with XP.

Impact of Recombinant Human Soluble Thrombomodulin for Disseminated Intravascular Coagulation.

BACKGROUND: Early treatment of disseminated intravascular coagulation (DIC) can be associated with improved early outcomes. We aimed to evaluate the effectiveness of recombinant human soluble thrombomodulin (rTM) administration in patients with peritonitis-induced DIC. PATIENTS AND METHODS: We treated 39 patients with DIC or pre-DIC caused by peritonitis at the Department of Surgery and Science, Kyushu University, and related facilities between January and December 2013. RESULTS: Patients surviving to 28 days after DIC treatment had significantly better platelet counts, DIC scores, and sequential organ failure assessment scores at 7 days than did those who died earlier than 28 days. Patients receiving rTM had significantly better overall survival rates at 28 days and the results of multivariate analysis showed that rTM administration for DIC treatment was a prognostic indicator of 28-day survival in patients with peritonitis. CONCLUSION: rTM administration for the treatment of DIC or pre-DIC complicated by peritonitis had acceptable early outcomes.
