Gas Gangrene of the Spleen Caused by Clostridium perfringens After Mild Blunt Trauma.

Splenic gas gangrene caused by Clostridium perfringens is rare. A 73-year-old woman was referred to our hospital because of fatigue, dyspnea, and left hypochondrial pain. She had a history of blunt trauma to the left abdomen eight days ago. She presented with hypoxemia and a high inflammatory response on blood tests. A CT showed left pleural effusion and gas in the spleen. She was treated with antimicrobials and underwent splenectomy. C. perfringens was identified from blood and intraoperative ascites cultures. She recovered and was discharged on day 34 of hospitalization. As C. perfringens is part of the normal gut microbiota and can translocate to other parts of the body, this bacterium should be considered a splenic abscess pathogen when an intracorporeal anaerobic environment is suspected.

Systemic inflammation score as a predictor of death within one year after esophagectomy.

BACKGROUND: After radical resection for esophageal cancer, death within 1 year of surgery can occur due both to recurrence and to other diseases, even after postoperative complications have been overcome. This study identified risk factors for early death within 1 year of esophagectomy for reasons other than death in hospital in patients undergoing esophagectomy for esophageal cancer or esophagogastric junction cancer. METHODS: We reviewed 366 patients who underwent esophagectomy without adjuvant treatment between January 2009 and July 2022 for thoracic esophageal cancer or esophagogastric junction cancer. Patients who died within 1 year excluding in-hospital death were compared with those who did not. Multivariable logistic regression analysis was used to identify predictors of death within 1 year after surgery. RESULTS: Death within 1 year occurred in 32 of 366 patients, 24 from primary disease and 8 from other diseases. Deaths within 1 year were significantly older than the other cases, had significantly lower % vital capacity (%VC), and occurred significantly more often in cases in advanced stages of disease. In a multivariable analysis, a systemic inflammation score (SIS) based on serum albumin level and lymphocyte-to-monocyte ratio was identified as an independent predictor of death within 1 year. As SIS increased, %VC decreased significantly, and CRP level and neutrophil-lymphocyte ratio increased significantly. There was no relationship between SIS and pN. Death within 1 year increased as SIS increased (p = 0.001 for trend). CONCLUSION: SIS assessment undertaken before beginning esophageal cancer treatment is a useful predictor of death within 1 year of surgery.

Safety and efficacy of atezolizumab plus bevacizumab combination therapy in patients with unresectable hepatocellular carcinoma undergoing dialysis: a case series.

Three patients aged 79, 75, and 81 years with unresectable hepatocellular carcinoma (HCC) and undergoing maintenance hemodialysis were treated with a combination of atezolizumab and bevacizumab. The patients, respectively, received their 22nd, 2nd, and 4th treatment cycles, and one achieved long-term stable disease. No serious adverse events, including immune-related adverse events, were observed in any patient. Remarkable progress has been made in chemotherapy for cancer; however, the efficacy and safety of chemotherapy in patients undergoing hemodialysis have not been adequately elucidated. This report provides novel insights into the feasibility and outcomes of atezolizumab and bevacizumab combination therapy in patients with HCC undergoing hemodialysis, highlighting its potential as a viable treatment option with manageable side effects.

Repair of Bile Duct Injury Using Indocyanine Green Following Laparoscopic Cholecystectomy.

Bile duct injury (BDI) is a potential complication that may arise during cholecystectomy and continues to occur with a certain frequency in the present day. Numerous reports have been published regarding the utilization of indocyanine green (ICG) for the prevention of biliary injury, and we feel that the importance of ICG is being recognized. In this context, we present a case wherein a BDI occurred following cholecystectomy, and ICG was employed for the safe repair of the biliary tract.
