A New Laparoscopic Surgical Procedure to Achieve Sufficient Mesorectal Excision in Upper Rectal Cancer

Objective. Mesorectal excision corresponding to the location of a tumor, termed tumor-specific mesorectal excision (TSME), is commonly performed for resection of upper rectal cancer. We devised a new laparoscopic procedure for sufficient TSME with rectal transection followed by mesorectal excision. Operative Technique. After mobilization of the sigmoid colon and ligation of inferior mesenteric vessels, we dissected the mesorectum along the layer of the planned total mesorectal excision. The rectal wall was carefully separated from the mesorectum at the appropriate anal side from the tumor. After the rectum was isolated and transected using an endoscopic linear stapler, the rectal stump drew immediately toward the anal side, enabling the mesorectum to be identified clearly. In this way, sufficient TSME can be performed easily and accurately. This technique has been successfully conducted on 19 patients. Conclusion. This laparoscopic technique is a feasible and reliable procedure for achieving sufficient TSME

A Successfully Treated Case of Intrahepatic Cholangiocarcinoma with Exacerbation of Dermatomyositis

Dermatomyositis (DM) is often found in conjunction with malignant tumors such as lung, cervical, and breast cancer. However, the association with intrahepatic cholangiocarcinoma (ICC) is extremely rare. Moreover, to our knowledge, there have been no previous reports of DM discovered because of exacerbation of DM. Our case was a 44-year-old female with dry cough, myalgia, and arthralgia. We performed hepatic resection for intrahepatic ICC. She was diagnosed with DM, and combination treatment with prednisolone and tacrolimus was started. During outpatient visits, her symptoms worsened, and she was hospitalized due to deterioration of her primary disease. On detailed examination, a malignant lesion in the liver was discovered. After operation, the symptoms of DM remain stable by taking prednisolone and tacrolimus. The patient was suspected to have paraneoplastic syndrome, which was discovered due to the exacerbation of the DM that was caused by the intrahepatic ICC

Complete response to preoperative chemoradiotherapy in highly advanced gastric adenocarcinoma

This report presents a case of highly advanced gastric cancer that achieved a histologically complete response (CR) to preoperative chemoradiotherapy with S-1 plus low-dose Cisplatin. A 60-year-old male patient underwent FDG positron emission tomography (PET) during a routine health examination. The patient was found to have swollen paraaortic lymph nodes. Shortly thereafter, he was diagnosed with gastric carcinoma with a type 2 tumor in the antrum with paraaortic lymph node metastases based on FDG-PET, endoscopic examination and abdominal computed tomography. After the completion of chemoradiation therapy (CRT), the tumor and the paraaortic lymph node metastases disappeared. The patient underwent surgery 5 wk after the completion of CRT, including a subtotal gastrectomy with Roux-en-Y reconstruction, D3 lymph node dissection and a left adrenalectomy. No cancer cells were detected in the resected specimen either in the primary lesion or lymph nodes, thus confirming a pathologically CR to CRT (CR grade 3). The patient has been stable and well without any evidence of recurrence for 48 mo after surgery. Such a preoperative CRT regimen might therefore be very effective for treatment of some advanced gastric cancers

A novel combined C‐reactive protein‐albumin ratio and modified albumin‐bilirubin score can predict long‐term outcomes in patients with hepatocellular carcinoma after hepatic resection

Abstract Background Systemic inflammatory response represented by C‐reactive protein and albumin ratio (CAR) and modified albumin‐bilirubin (mALBI) grade both have been associated with long‐term outcome in patients with hepatocellular carcinoma (HCC). In this study, we investigated the prognostic utility of combined score of CAR and mALBI score to predict the prognosis of HCC patients after hepatic resection. Methods This study included 214 patients who had undergone primary hepatic resection for HCC between 2008 and 2018. Systemic inflammatory response and mALBI were evaluated preoperatively and patients were classified into three groups based on the combination of CAR and mALBI score: low CAR and low mALBI grade (score 0), either high CAR or high mALBI grade (score 1), and both high CAR and high mALBI grade ≥2b (score 2). Multivariate Cox proportional hazard models were conducted to assess disease‐free and overall survival. Results In multivariate analysis, sex (p < 0.01), HBsAg positivity (p < 0.01), serum AFP level ≥20 ng/mL (p < 0.01), microvascular invasion (p = 0.02), multiple tumors (p < 0.01), type of resection (p < 0.01), and CAR‐mALBI score ≥2 (HR 2.19, 95% CI 1.39–3.44, p < 0.01) were independent prognostic factors of disease‐free survival, while sex (p = 0.01), HBsAg positivity (p < 0.01), poor tumor differentiation (p = 0.03), multiple tumors (p < 0.01), CAR‐mALBI score ≥2 (HR 2.70, 95% CI 1.51–4.83, p < 0.01) were independent prognostic factors of overall survival. Conclusions CAR‐mALBI score is associated with disease‐free and overall survival in patients with HCC after hepatic resection, suggesting the importance of evaluating both hepatic functional reserve and host‐inflammatory state in the risk assessment of HCC patients
