Chemotherapy-induced nausea and vomiting(CINV)are typical side effects caused by chemotherapy. We analyzed CINV during first-line chemotherapy for gastric cancer.Thirty-one patients who received first-line chemotherapy for gastric cancer were retrospectively assessed for CINV.The median age was 70 years, and the gender(male/female)was 23/8 cases. NK1 receptor antagonist, 5-HT3 receptor antagonist, and dexamethasone were used as antiemetic agents in 29 patients(94%). Sixteen patients(52%)had Grade 1 or higher nausea, and 6 patients (19%)had Grade 1 or higher vomiting, and complete control of nausea and vomiting was achieved in 21 patients(68%). Nausea was significantly more frequent in patients with liver metastasis(p=0.0008), but there was no significant difference in vomiting(p=1.0000). There was no significant difference in the occurrence of CINV between chemotherapy regimens or combination of olanzapine.During first-line chemotherapy for gastric cancer, 3 antiemetic agents were used in 94% of cases, and the complete control rate of CINV was 67.8%.

Background There is no consensus on the optimal timing of laparoscopic cholecystectomy (LC) after gallbladder drainage for acute cholecystitis (AC). To obtain evidence for a consensus, we investigated surgical outcomes of LC after gallbladder drainage with respect to the time elapsed from gallbladder drainage to surgery in a multi-institutional retrospective study. Methods This study enrolled 347 patients who underwent LC after gallbladder drainage for AC at 15 institutions. Surgical outcome of LC was investigated in the cases based on the interval from gallbladder drainage to surgery. Results The median interval from gallbladder drainage to surgery of the patients was 34 days, with a mean ± standard deviation of 58 ± 99 days. Patients were divided into four groups based on quartiles of the interval: Group A, cases with an interval of 1-12 days; Group B, cases with an interval of 13-34 days; Group C, cases with an interval of 35-73 days; and Group D, cases with an interval of ≥74 days. Surgical outcomes, which were evaluated with respect to intraoperative blood loss, operation time, postoperative hospital stay, rate of intraoperative accident, conversion from laparoscopic to open surgery, and postoperative complication, were worse in Group B than in the other groups. The finding was verified by propensity score-matched analysis. Conclusions Surgical outcome of LC after gallbladder drainage for AC was inferior in Group B compared with the other groups. This finding could be useful for determining the optimal timing of LC after gallbladder drainage for AC.

A 71-year-old male had repeated resection and transcatheter arterial chemo-embolization(TACE)for hepatocellular carcinoma(HCC). Treatment with lenvatinib was started due to multiple liver recurrences and peritoneal disseminations. Since only the disseminated lesion had increased, it was decided to perform laparoscopic resection. Indocyanine green(ICG) was intravenously injected the day before surgery. Disseminated lesions could be easily detected with intraoperative fluorescence imaging, and we could completely resect disseminated lesions. The ICG fluorescence could be considered to be useful in laparoscopic resection for peritoneal dissemination of HCC.

A 67-year-old woman with a pancreatic cancer diagnosed by endoscopic ultrasound with fine needle aspiration(EUS- FNA)was underwent distal pancreatectomy. Two years and 10 months after the operation, a computed tomography scan revealed a tumor in the posterior wall of the lower body of the stomach. Upper gastrointestinal endoscopy showed a 15 mm-sized submucosal tumor on the posterior wall of the angular region, and its biopsy showed tubular adenocarcinoma that it was resembling the resected pancreatic cancer. Needle tract seeding(NTS)of the pancreatic cancer to the gastric wall was suspected. After 5 courses of chemotherapy with gemcitabine and nab-paclitaxel, the tumor shrank and there were no other signs of metastasis, we performed distal gastrectomy. The pathological findings of the resected specimen showed a tubular adenocarcinoma, consistent with the primary pancreatic tumor. We finally diagnosed as the NTS of the pancreatic cancer to the gastric wall. In the case of EUS-FNA for the body or tail tumor of pancreas, it should be paid attention to the recurrence due to NTS because the surgical resection does not include the needle tract site.

We report a case of advanced gastric cancer that was successfully treated with mFOLFOX6 therapy. A 78-year-old man presented to our hospital with a chief complaint of weight loss. Esophagogastroduodenoscopy(EGD)and computed tomography( CT)revealed the presence of type 3 advanced gastric cancer with distant lymph node metastasis and peritoneal dissemination. Biopsy specimen examination revealed moderately differentiated adenocarcinoma with a HER2 score of 1. Chemotherapy comprising 5-fluorouracil, Leucovorin, and oxaliplatin(mFOLFOX6)was administered because of renal failure. Subsequently, the gastric lesion, distant lymph node metastasis, and peritoneal dissemination were seen to be reduced on EGD and CT. After 7 courses, the regimen was changed to 5-fluorouracil and Leucovorin(5-FU/l -LV)chemotherapy because of thrombocytopenia. For more than 10 months, he has continued to receive chemotherapy without the recurrence of metastasis.

A 74‒year‒old man was diagnosed with advanced gastric cancer with para‒aortic lymph node metastasis and ascites. He has been treated with S‒1 plus oxaliplatin as the primary treatment, paclitaxel plus ramucirumab as the secondary treatment and CPT‒11 as the third‒line treatment, but the effect of all treatments were temporary and left adrenal metastasis appeared during the course. Nivolumab was started as the fourth‒line treatment. Two months later, para‒aortic lymph nodes and left adrenal metastasis were markedly shrank and ascites disappeared. A 79 years old woman was performed proximal gastrectomy for advanced gastric cancer of the upper stomach. S‒1 therapy was started as adjuvant chemotherapy, but tumor markers have been increased and para‒aortic lymph node recurrence was observed 4 months after the operation. After ramucirumab as the primary treatment was ineffective, nivolumab was started as the secondary treatment. Two months later, para‒aortic lymph nodes shrank below the significant size and tumor markers were normalized.

A 65-year-old male received the positive result of fecal occult blood. Colonoscopy was performed to reveal a tumor in the ascending colon. The result of biopsy was neuroendocrine carcinoma. Under the preoperative diagnosis of neuroendocrine carcinoma in the ascending colon, cT3N0M0, cStage Ⅱ, laparoscopic ileocecal resection with D3 lymph node dissection was performed. The pathological result was neuroendocrine carcinoma in the ascending colon, pT4aN2M0, pStage Ⅲc. The R0 resection was achieved. As adjuvant chemotherapy, the regimen of cisplatin plus irinotecan was administered for 4 courses. No recurrence was seen until 9 months after the operation, when multiple peritoneal and hepatic metastasis were detected on CT scan. The chemotherapy regimen of etoposide plus carboplatin was started and is now ongoing. The patient is now alive 13 months after the operation.

A 76-year-old man had undergone right lobectomy after transcatheter arterial chemoembolization(TACE)for hepatocellular carcinoma(HCC)in segment 5/6 of the liver. He had undergone TACE for intrahepatic recurrence in segment 1 eight months after the operation. Abdominal CT revealed intrahepatic recurrence in segment 2 and segment 3 and a hepatic portal lymph node swelling 13 months after the operation, he underwent TACE and radiofrequency ablation for intrahepatic lesions. There was neither intrahepatic recurrences nor new extrahepatic lesions, and the hepatic portal lymph node resection was performed. He was discharged on postoperative day 8, and there has been no subsequent recurrence over 42 months after initial treatment. The lymph node metastasis of HCC is rare and systemic chemotherapy such as molecular targeted argent is the standard treatment, but its prognosis is poor. When a patient has a resectable metastasis with controlled intrahepatic lesions, lymph node resection appears to be an effective option.

A 71-year-old man underwent laparoscopic lower anterior resection(D3 dissection)for rectal cancer and bilateral lung metastases. Histopathological findings indicated Ra, type 2, tub2, ly0, v2, pN0, pM1(PUL1), pStage Ⅳ. The lung metastases had disappeared after postoperative chemotherapy and the patient entered cCR. Two years after the surgery, the patient's anal fistulas appeared sclerotic. Biopsy revealed recurrent rectal cancer. We performed an abdominoperineal resection and rectus abdominis muscle flap. Currently, the patient is alive at 9 months after surgery with no re-recurrence.

We report a case ofadvanced colon cancer, stage cT4bN0M0 in the descending colon with formation ofabscesses in the retroperitoneal space ofa 66-year-old woman. After constructing a transverse colostomy and percutaneous abscess drainage, chemotherapy was initiated with CAPOX. After 4 courses of CAPOX, the tumor had significantly regressed; therefore, the regimen was switched to a triplet combination called CAPOXIRI. After 3 courses of CAPOXIRI, the tumor had become smaller and had separated from the iliopsoas muscle, which led us to perform surgical resection. Left hemicolectomy was performed with R0 resection, and the tumor was pathologically diagnosed as ypT3N0M0. The patient is alive 12 months after the surgery, with no signs of recurrence.

In general, distant metastasis is uncommon in colorectal submucosal(SM)invasion without lymph node metastasis. We experienced an extremely rare case of synchronous pulmonary metastases for colon cancer in SM invasion. A man in his 70s was seen at the hospital for a positive fecal occult blood test. Colonoscopy revealed 3 lesions in the sigmoid colon and endoscopic mucosalresection revealed 2,000 mm SM invasion in all 3 lesions. Computed tomography showed no signs of distant lymph node or liver metastasis but showed small nodules in both lungs. Radical treatment included laparoscopic anterior resection with lymph node dissection. Histological examination showed no residual tumor in the colon and no lymph node metastasis. Two years after surgery, the number of lung nodules gradually increased and we performed partial resection of the left lung, which was diagnosed as pulmonary metastasis from colon cancer by histological examination. Therefore, we resected the opposite-side pulmonary metastases. The patient has exhibited no other signs of recurrence in the 2 years since the last operation.

A 73-year-old man underwent a subtotal stomach preserving pancreaticoduodenectomy(SSPPD)for biliary carcinoma without regional lymph node metastasis. Although S-1 was administrated as adjuvant chemotherapy after the operation, the serum CA19-9 level was gradually elevated, and a liver metastasis of 27mm in diameter was detected in Couinaud's segment 8 during chemotherapy. We administrated gemcitabine(GEM)and cisplatin(CDDP)combination therapy(GC therapy). The liver tumor was immediately shrunk to 6mm and kept up the PR state after 15 courses of GC therapy. A stereotactic body radiation therapy(SBRT)was performed 1 year 8 months after the operation. The patient has been alive without recurrence for 4 years since the SBRT. Although systemic chemotherapy is the standard treatment for the recurrence of biliary carcinoma, a loco-regional therapy such as SBRT may be an effective alternative when a patient has a solitary metastasis to the liver with no other evidence of recurrence.

The patient was a man in his 70s who visited our hospital to undergo an examination for fecal occult blood, which detected a 20 mm, Ⅱa lesion in the lower rectum on colonoscopy. He was diagnosed with SM-invasive cancer and was planned to undergo trans-anal local excision. After the surgery, he had a good postoperative course without complications. The pathological findings were Ⅱa, tub1, 22×16 mm, pT1a(950 mm), int, INF a, ly0, v0, pHM0, pVM0(300 mm). He was followed up after the surgery, but was diagnosed with lateral lymph node recurrence 4 years after a local surgery. The surgery involved right-sided lateral lymphadenectomy with resection of the ureter, spermatic duct, seminal vesicle, and piriformis muscle. He was diagnosed with lymph node metastasis with invasion of the spermatic duct based on pathology. Eight courses of adjuvant chemotherapy containing CapeOX was administered. Unfortunately, primary squamous cell lung cancer was detected, and he died after surgery for recurrence in the second year. It is suggested that it is necessary to note lateral lymph node recurrence on postoperative follow-up for lower rectal cancer at any stage.

In general, anastomotic recurrence of colorectal cancer occurs within 3 years after surgery. We encountered an extremely rare case of anastomotic recurrence over 20 years after surgery. A 70-year-old woman who had undergone low anterior resection for rectal cancer 22 years previously was admitted to the hospital because of anal bleeding. Colonoscopy revealed a 1.5 cm sized, elevated lesion on the anastomotic site, and a biopsy revealed an adenocarcinoma(tub2). EUS demonstrated that the tumor was located on the staples, and the depth of the tumor was expected to be within the muscle layer of the rectum. Computed tomography showed no signs of distant metastasis. Given the diagnosis of anastomotic recurrence of rectalcancer 22 years after surgery, laparoscopic abdominoperinealresection was performed. Histologicalassessment showed that the tumor was on the staples, and did not exhibit vascular and lymphatic invasion. Finally, she was diagnosed with anastomotic recurrence due to implantation. The patient has exhibited no other signs of recurrence in the 3 years since the last surgery.

Creation of a cholecystojejunostomy has been recommended as one option in the palliation of biliary obstruction due to pancreatic carcinoma.However, it was a technique used for biliary drainage for acute cholecystitis a long time ago.We describe a patient who underwent a cholecystojejunostomy for acute cholecystitis 50 years prior to presentation, and then revealed a gallbladder carcinoma.

A 70's woman with a history of abdominal surgery for gastric cancer visited our hospital for the evaluation of bleeding during defecation.We diagnosed her with advanced rectal cancer and performed laparoscopic low anterior resection.As postoperative pathological staging was pT3N2M0, pStage III b, we included CapeOx therapy as adjuvant chemotherapy.One year and 4 months after the surgery, lung and liver metastases were revealed by CT and PET-CT scans.At the same time, dilatation of the main pancreatic duct(intraductal papillary mucinous neoplasm: IPMN)was detected.Thus, we first performed liver resection and then lung resection.After the surgery, new lung nodules and a mass lesion with IPMN with superior mesenteric venous invasion was found on CT scans.We then administered chemo-radiation therapy(CRT).After CRT, the lung and pancreatic lesions seemed to decrease slightly.Accidentally, a nodule on the cystic bladder was found, resected by transurethral resection of the bladder tumor(TUR-Bt), and diagnosed as a bladder cancer.Thirty months after the rectal surgery, she is continuing the S-1 chemotherapy with stable disease.

We prove the safety and feasibility of single-incision plus 1 port (SILS+1) laparoscopic total mesorectal excision (TME) + lateral pelvic lymph node dissection (LPLD) via a medial umbilical approach for rectal cancer. Only a few reports have been published about single-incision multiport laparoscopic low anterior resection with LPLD. Recently, minimally invasive surgery such as single-incision plus 1 port (SILS + 1) for advanced rectal cancer has been reported as safe and feasible. To our knowledge, this is the first reported case of SILS + 1 used for LPLD. A wound protector was inserted through a 30-mm transumbilical incision. Next, a single-port access device was mounted to the wound protector and 3 ports (5 mm each) were placed. A 12-mm port was inserted in the right lower quadrant. Super-low anterior resection of the rectum and bilateral LPLD and temporary ileostomy were performed with SILS + 1, with a blood loss of 50 mL and a total surgical time of 525 minutes. The time for right lateral dissection was 74 minutes; the time for left lateral dissection was 118 minutes. The total number of dissected lymph nodes was 57 and the number of lateral lymph nodes dissected was 21 (8 left pelvic lymph nodes, 13 right pelvic lymph nodes). No postoperative anastomotic insufficiency or voiding dysfunction was observed. We have documented the safety and feasibility of SILS + 1-TME + LPLD via a medial umbilical approach for rectal cancer.

With regard to laparoscopic and robotic abdominoperineal resection (APR) for primary rectal malignancies, limited data have been published in the literature. Single-incision laparoscopic surgery (SLS) has been successfully introduced for treating colorectal cancer. Here we describe our experience of APR with SLS plus one port (SLS + 1) for treating advanced rectal cancer. A 65-year-old man underwent the procedure, which involved a 35-mm incision in the left side of the umbilicus for the insertion of a single multichannel port as well as the insertion of a 5-mm port into the right lower quadrant. The sigmoid colon and rectum were mobilized from the pelvic floor using a medial and lateral approach. After the rectum with the mesorectum was completely mobilized according to the total mesorectal excision, the sigmoid colon was intracorporeally transected. The specimen was removed through the perineal wound. Terminal colostomy was fashioned at the left lower trocar site. Lateral pelvic lymph node dissection was bilaterally performed. There were no perioperative complications. The total operating time was 592 minutes, and the estimated blood loss was 180 mL. To our knowledge, this is the first reported case of SLS + 1 APR with lateral pelvic lymph node dissection for treating rectal cancer. We conclude that SLS + 1 APR is a technically promising alternative method for treating selected patients with advanced rectal cancer.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal neoplasm that spreads to surrounding tissue or distant sites. This study investigated distant metastases in PDAC patients with or without preoperative chemoradiation therapy (CRT), focusing on vitamin D levels and bone density. This study included 146 patients with PDAC who underwent surgery from 2007 to 2014. Bone density was evaluated using computed tomography, and the preoperative vitamin D level was calculated by enzyme-linked immunosorbent assay (ELISA) for patients with available plasma (48 cases). When the patients were divided into two groups according to the change in bone density, the group with decreased bone density had a shorter distant metastasis-free survival time (DMFS) after surgery than the other group (p

Unresectable advanced esophageal cancer is often treated with chemotherapy or chemoradiotherapy(CRT). Nutritional disorders caused by dysphagia may lead to a poor prognosis. Placing a PEG before starting CRT for advanced esophageal cancer may maintain better nutritional status.The purpose of this study is to evaluate the clinical significance of placing a PEG before starting CRT for advanced esophageal cancer.Fifty-one cases were evaluated, 22 PEG (+) and 29 PEG (-). The rate of a CRT was better in PEG (+) than PEG (-) cases (91% vs 79%). Infection around the PEG was the only type of complication, affecting 5%.PEG feeding during CRT is important in the development of effective treatments for unresectable advanced esophageal cancer.

The first case is a 72-year-old man who underwent(palliative)anterior segmentectomy for multiple hepatocellular carcinoma tumors with a maximum diameter of 10 cm at the age of 70 years. The hepatic lesion was well controlled for some time by trans-catheter arterial chemoembolization (TACE). However, left adrenalectomy was performed 17 months after surgery when metastasis to the left adrenal gland was found. The postoperative course was uneventful and he has not experienced recurrence for 7 months. The second case is a 69-year-old man who underwent TACE at the age of 68 years because of multiple hepatocellular carcinoma tumors with a maximum diameter of 15 mm. The hepatic lesion was well controlled for some time. However, a left adrenalectomy was performed at the age of 70 years when metastasis to the left adrenal gland was found. The postoperative course was uneventful and he has not experienced recurrence for 5 months. We investigated 157 additional cases of adrenal metastasis of hepatocellular cancer. Treatments for adrenal metastases included surgical resection, artery embolization, and ethanol injection therapy, but long-term survival was most commonly observed when surgical resection was used. When the primary tumor that metastasized to the adrenal gland was controllable and no other metastases were observed, active resection was indicated.
