[A Case of DIC Following Mixed Acidosis during Laparoscopic Hepatectomy].

The patient was an 81-year-old man. Laparoscopic sigmoidectomy was performed for a sigmoid colon cancer(S, type 2, pT3[SS], INF a, Ly0, V0, BD1, Pn0, pPM0, pDM0, RM0, pN0, pM0, pStage Ⅲa, R0, Cur A). One year after the surgery, a blood test showed CEA as high as 68.

Frailty is a useful predictive marker of postoperative complications after pancreaticoduodenectomy.

Background: Frailty results in a high risk for disability, hospitalization, and mortality. This study aimed to investigate perioperative details of frail patients who underwent pancreatectomy and whether frailty can be a predictive factor of postoperative complications, especially of clinically relevant postoperative pancreatic fistula (CR-POPF).

Methods: This retrospective study included patients who underwent pancreatectomy in our hospital between August 2016 and March 2019.

The impact of epidural catheter insertion level on pain control after esophagectomy for esophageal cancer.

Background: Although the effectiveness of epidural anesthesia on pain control after esophagectomy has been reported, the appropriate insertion level of the epidural catheter remains unclear for adequate postoperative pain control. We investigated the relationship between the epidural catheter insertion level and postoperative pain control after esophagectomy for esophageal cancer.

Methods: We analyzed retrospectively 63 patients who underwent McKeown esophagectomy for esophageal cancer between October 2014 and November 2018.

[A Case of Giant Hematogenous Left Quadricep Muscle Metastasis of Hepatocellular Carcinoma].

The patient was a 62-year-old man with no specific medical history. Lateral segmentectomy was performed for hepatocellular carcinoma with a tumor size of approximately 14×13 cm. The histopathological diagnosis was moderately differentiated hepatocellular carcinoma: Fc(-), Fc-Inf(-), Sf(-), S0, N0, Vp2, Vv1, Va0, B0, P0, SM(-), CH.

Laparoscopic completion gastrectomy in elderly patients with remnant gastric cancer: a case series.

Background: Open completion gastrectomy (OCG) has been selected to treat remnant gastric cancer (RGC) due to severe adhesions and difficulty recognizing anatomical orientation after primary gastrectomy. In general, elderly individuals' physiological reserves gradually decrease. Moreover, elderly patients (EPs) often have multiple complicating factors (i.

Life-threatening giant esophageal neurofibroma with severe tracheal stenosis: a case report.

Background: Benign esophageal tumors are relatively rare, and a neurofibroma in the esophagus is extremely rare. Dysphagia is the most common clinical manifestation in patients with esophageal neurofibroma, and no cases of giant esophageal neurofibroma with severe tracheal stenosis have been reported.

Case Presentation: A 73-year-old woman presented with shortness of breath, and computed tomography scan exhibited a giant mediastinal tumor causing severe tracheal stenosis.

Laparoscopic total gastrectomy for remnant gastric cancer: A single-institution experience.

Introduction: The incidence of remnant gastric cancer is increasing because of past use of subtotal gastrectomy to treat peptic ulcer and increased survival rates after radical gastrectomy for gastric cancer. The feasibility and advantages of laparoscopic total gastrectomy (LTG) for remnant gastric cancer remain unclear. Therefore, we aimed to investigate the safety, feasibility, and clinical short-term outcomes of LTG for remnant gastric cancer.

[Stereotactic Body Radiotherapy with CyberKnife®for Liver Metastases from Colorectal Cancer].

For treatment of colorectal liver metastases, liver resection is recommended for resectable cases in the clinical guidelines for colorectal cancer. On the other hand, there are currently no data supporting the efficacy of radiation therapy as a topical treatment, and this treatment can therefore not presently be recommended. With CyberKnife®, it is possible to perform stereotactic radiation therapy using a linear accelerator with high accuracy, even for lesions in the trunk area such as liver metastases.

[A case of gastric cancer showing response to first-line XP regimen after lymph node recurrence during the administration of S-1 as postoperative adjuvant chemotherapy].

We report on a patient who underwent total gastrectomy with D2 lymph node dissection for metastatic gastric cancer. We administered S-1 at 60 mg/m² as postoperative adjuvant chemotherapy. Six months after surgery, recurrence was detected in the para-aortic lymph node.

[Nanoparticle albumin-bound Paclitaxel for unresectable or recurrent gastric cancer].

The efficacy and safety of nanoparticle albumin-bound paclitaxel(nab-paclitaxel)administered every 3 weeks for unresectable or recurrent gastric cancer was evaluated retrospectively. Nab-paclitaxel was intravenously administered at 260 mg/ m² on day 1 of each 21-day course without anti-allergic premedication until disease progression or discontinuation. Nine patients received nab-paclitaxel.

[A case of metachronous ovarian metastasis after curative surgery of colon cancer with simultaneous hepatic metastasis].

The patient was a 51-year-old woman who presented with nausea, vomiting, and abdominal pain. Detailed examination revealed a carcinoma of the descending colon with simultaneous hepatic metastasis. Because the carcinoma comprised a circumferential stenotic lesion and resection of the hepatic metastasis was feasible, combined left hemicolectomy and hepatectomy were initially performed.

[A case of liver metastasis from esophageal cancer treated with stereotactic body radiation therapy].

A 70-year-old woman was diagnosed as having advanced lower thoracic esophageal cancer with abdominal lymph node metastases(T3N1M0, Stage III). After administering 2 courses of neoadjuvant chemotherapy with 5-fluorouracil(5- FU)( 800 mg/m2)and cisplatin(80 mg/m2), we performed curative surgery with D2 lymph node dissection. The patient could not receive adjuvant chemotherapy because of her poor performance status.

[Neoadjuvant chemotherapy with capecitabine plus oxaliplatin and bevacizumab for the treatment of patients with resectable metastatic colorectal cancer].

We analyzed the clinical efficacy and safety of capecitabine plus oxaliplatin( XELOX) and bevacizumab( BV) as neoadjuvant chemotherapy, administered for the treatment of patients with resectable metastatic colorectal cancer between October 2009 and December 2012. Of the 15 patients who received chemotherapy, 9 received XELOX plus BV and 6 patients received XELOX alone. The median number of therapy courses was 4.

[Adjuvant chemotherapy with S-1 plus docetaxel for highly advanced gastric cancer patients].

Background: Adjuvant chemotherapy with S-1 monotherapy might be insufficient for Stage IIIB highly advanced gastric cancer patients. Our retrospective study was to evaluate the feasibility and safety of adjuvant chemotherapy with S-1 plus docetaxel.

Methods: S-1 (80 mg/m2) was administered orally for 2 weeks then followed by a 1-week rest period.

[Efficacy and safety of biweekly nedaplatin in combination with docetaxel as second-line chemotherapy in patients with unresectable or recurrent esophageal cancer].

There is no standard approach for second-line chemotherapy after a failure of the first-line regimen, fluorouracil and cisplatin -based chemotherapy in patients with unresectable or recurrent esophageal cancer. We have treated with biweekly nedaplatin (CDGP 40 mg/m²) in combination with docetaxe (l DOC 30 mg/m²) as second-line chemotherapy and investigated its efficacy and safety. Fifteen patients were retrospectively assessed in this study.

[A case report-highly advanced gastric cancer leading to perforation during neoadjuvant chemotherapy with docetaxel, cisplatin and S-1].

A 70-year-old man was found to have advanced gastric cancer with a deep ulcer and multiple lymph-node metastases. Although the tumor was resectable, we predicted that the patient would have a poor outcome. We therefore administered neoadjuvant chemotherapy with docetaxel, cisplatin, and S-1 to improve the prognosis before curative resection.

[Laparoscopic partial gastrectomy for gastric submucosal tumor-indications and limitations of single-incision laparoscopic surgery].

Because gastric submucosal tumors can be treated by local resection without lymph-node dissection, laparoscopic local resection is widely used to manage relatively small tumors less than 5 cm in diameter. On the other hand, single-incision laparoscopic surgery (SILS) to perform laparoscopic cholecystectomy was feasible. SILS requires only a single incision in the umbilical region; it has better cosmetic outcomes than conventional laparoscopic surgery.

[Highly advanced gastric cancer that responded to neoadjuvant combination chemotherapy with docetaxel/CDDP/S-1 (DCS)].

A 60-year-old male was found to have advanced gastric cancer and multiple lymph node metastases. Since curative surgery was concluded to be unfeasible, we tried neoadjuvant chemotherapy with the aim of controlling the lymph node metastasis. S-1 (80 mg/m2) was administered orally for two weeks then followed by 2-week rest period.

[A partial response to S-1 as second-line chemotherapy in a patient with unresectable pancreatic cancer].

A male in his fifties presented with a primary complaint of abdominal distension and appetite loss. CT revealed a primary pancreatic tumor with massive ascites. The patient was treated with gemcitabine as the first-line chemotherapy.
