RESUMEN
OBJECTIVES: In the 9th edition of the Japanese Classification of Colorectal, Appendiceal, and Anal Carcinoma (JCCRC), ovarian metastasis is classified as distant metastasis. We assessed the significance of resection of ovarian metastases and the validity of this 9th edition of JCCRC for ovarian metastases from colorectal cancer (CRC). METHODS: We retrospectively analyzed the clinicopathological factors and overall survival of 17 patients with ovarian metastases from CRC who underwent resection and 110 female CRC patients with Stage IV (M1a) disease. RESULTS: The patients with only ovarian metastases who underwent resection had a longer median survival time than patients with both ovarian and peritoneal metastases who underwent resection (45.4 months vs. 9.3 months, P = 0.029). The 5-year overall survival of the patients with only ovarian metastases who underwent R0 resection was as long as that of the female Stage IV (M1a) CRC patients after R0 resection (50% vs. 48%, P = 0.334). CONCLUSIONS: We found that, after resection, patients with only ovarian metastases had significantly better prognoses than patients with ovarian and peritoneal metastases. R0 resection of ovarian metastasis indicated as good prognosis as R0 resection of metastasis to one distant organ without ovaries. So the 9th edition of JCCRC, which classifies ovarian metastasis from CRC as distant metastasis, is appropriate.
RESUMEN
CASE: A 77-year-old woman was referred to our hospital for detailed examination of a cystic liver tumor. Contrast-enhanced CT and MRIshowed a cystic liver tumor with an enhanced mural nodule in S6 of the liver. Under a preoperative diagnosis of hemorrhagic hepatic cyst and mucinous cystic neoplasm(MCN)of the liver, extended posterior segmentectomy was performed. Histological examination of the tumor revealed no neoplastic cells, and the tumor was finally diagnosed as a hemorrhagic hepatic cyst of the liver. CONCLUSION: Similar to previous reports of hemorrhagic hepatic cysts, preoperative differential diagnosis from MCN of the liver was difficult in this case. Hemorrhagic hepatic cysts are rare and are sometimes confused with MCN of the liver, especially when an enhanced mural nodule is found in the cyst. The possibility of hemorrhagic hepatic cysts should be considered during diagnosis of liver cystic tumors.

A 70-year-old woman underwent treatment for cecal cancer(pT4bN1M0, Stage â ¢b)in 2010. Four years and 2 months after the first surgery, she underwent ileum resection for stenosis due to perineal dissemination(P3). Two years after this recurrence, during which time she had completed 26 courses of FOLFIRI plus bevacizumab(Bmab), 9 courses of capecitabine plus oxaliplatin(CapeOX)plus Bmab, and 3 courses of Cape, no peritoneal dissemination was detected by computed tomography( CT). Thereafter, an additional 19 courses of Cape plus Bmab were introduced, but CEA continued to increase. Right ovarian metastasis was suspected based on CT and FDG-PET/CT examination. Four years and 1 month after the initial recurrence of perineal dissemination, the patient underwent bilateral ovarian resection, during which the lack of peritoneal dissemination was confirmed. Pathologically, right ovarian metastasis was diagnosed. The patient is still alive 4 years and 6 months after the first operation.

Multiple sporadic gastrointestinal stromal tumor(GIST)are rare, except for those restricted to von Recklinghausen disease or hereditary conditions.We reported a case of a gastric GIST resected 9 years after the resection of a duodenal GIST.The patient was a 58-year-old male who had been followed-up with computed tomography scans after pancreatoduodenectomy for a duodenal GIST when he was 49-years-old.The patient was admitted to our hospital for anemia examination.A CT scan detected a tumor in the stomach, with a diameter of over 10 cm, and necrosis.Esophagogastroduodenoscopy revealed the presence of a delle on the gastric SMT.Due to suspected invasion of the spleen and left diaphragm by the tumor, we performed subtotal gastrectomy with splenectomy and left diaphragm segmental resection.In the pathological diagnosis, the tumor was diagnosed as a gastric GIST, because the cell type of the tumor was spindle and tested positive for c-kit.Based on the tumor size and mitotic count, the patient was diagnosed with high-risk GIST by the modified-Fletcher classification, and imatinib 400mg/day was administered.There have been no signs of recurrence for 2 years since the operation.

We describe a case of residual stomach preserving surgery performed under evaluation of residual gastric blood flow with indocyanine green(ICG)fluorography, for gastric cancer with recurrence of splenic lymph node metastasis after distal gastrectomy( DG)in a 65-year-old man. After 4 courses of S-1 plus CDDP(SP)therapy for advanced gastric cancer with ascites, DG, D2 dissection, and Billroth â reconstruction were performed and radical resection was obtained(L, Type 3, pap/tub, ypT3N1H0P0CY0M0, ypStage â ¡B). Three years and 6 months after the surgery, a mass 4 cm in diameter was found in the splenic hilum, and a pancreatosplenial resection was performed to remove the tumor for diagnosis and treatment purposes. We confirmed that there was no problem with blood flow, and we were able to preserve the stomach. Intraoperative ICG fluorescence imaging was considered a promising method for evaluating residual gastric blood flow.

This report describes a case of primary adenosquamous carcinoma of the liver with hepatolithiasis. A 70's man was followed up at a clinic for hepatolithiasis, gallbladder stone, and dilatation of the intrahepatic duct. He visited our hospital for computed tomography(CT)examination. CT showed a 30mm diameter low-density mass in the S2 liver and dilatation of the intrahe- patic duct filled with hepatolithiasis. Blood examination showed elevated levels of tumor markers(CEA 8.0 ng/mL, CA19-9 19,196 U/mL). We diagnosed the tumor as cholangiocellular carcinoma(cT2N1M0, cStage â £A)with hepatolithiasis and performed left hepatectomy and lymphadenectomy. In the specimen, a 39×22mm diameter solid tumor was detected and the intrahepatic duct was filled with haptolithiasis. Pathologically, a mixture of adenocarcinoma and squamous cell carcinoma was observed adjacent to the bile duct. Accordingly, a diagnosis of adenosquamous carcinoma was made(pT3N0M0, pStage â ¢). Multiple liver metastases were detected 8 months after the operation, and chemotherapy was started. He remains alive 11 months after the operation. We experienced a rare case of adenosquamous carcinoma in the liver with hepatolithiasis.

There have been few reports discussing treatments for primary duodenal cancer. In this study, 15 cases of primary duodenal cancer that were treated by curative resection in our hospital between April 2005 and December 2017 were analyzed to study appropriate operative procedures. Prognostic analysis revealed that the median of relapse-free survival and overall survival were 49 months and 74 months, respectively. The 5-year survival rate was 47%. On univariate analysis of relapse-free survival, lymph node metastasis(p<0.01)and post-operative adjuvant therapy(p=0.02)were significant independent prognostic factors. Analysis of the relationship between lymph node metastasis and the depth or location of tumors suggested that pancreaticoduodenectomy with lymph node dissection should be performed to achieve radical resection, since there were some cases that involved lymph node metastasis around the pancreatic head or hepatoduodenal ligament.

A60s woman was followed-up regularly for primary biliary cholangitis and a solitary enlarging hepatic mass in the S6 segment of her liver was discovered by ultrasonography. We diagnosed the mass as hepatocellular carcinoma by contrast ultrasonography, contrast computed tomography, and ethoxbenzyl magnetic resonance imaging and laparoscopic partial hepatectomy of S6 segment was performed. The resected specimen was histopathologicaly diagnosed as liver-reactive lymphoid hyperplasia(RLH). The patient is alive without recurrence 17 months after the surgery. Although liver RLH is a rare disease, it should be considered in the differential diagnosis of small liver tumors.

BACKGROUND: With the improvement of sensor technology, the trend of Internet of Things (IoT) is affecting the medical devices. The aim of this study is to verify whether it is possible to "visualize instrument usage in specific procedures" by automatically accumulating the digital data related to the behavior of surgical instruments/forceps in laparoscopic surgery. METHODS: Five board-certified surgeons (PGY 9-24 years) performed laparoscopic cholecystectomy on 35-kg porcine (n = 5). Radio frequency identifier (RFID) was attached to each forceps with RFID readers installed on the left/right of the operating table. We automatically recorded the behavior by tracking the operator's right/left hands' forceps with RFID. The output sensor was installed in the electrocautery circuit for automatic recordings of the ON/OFF times and the activation time. All data were collected in dedicated software and used for analysis. RESULTS: In all cases, the behaviors of forceps and electrocautery were successfully recorded. The median operation time was 1828 s (range 1159-2962 s), of which the electrocautery probe was the longest held on the right hand (1179 s, 75%), followed by Maryland dissectors (149 s, 10%), then clip appliers (91 s, 2%). In contrast, grasping forceps were mainly used in the left hand (1780 s, 93%). The activation time of electrocautery was only 8% of the total use and the remaining was mainly used for dissection. These situations were seen in common by all operators, but as a mentor surgeon, there was a tendency to change the right hand's instruments more frequently. The median activation time of electrocautery was 0.41 s, and these were confirmed to be 0.14-0.57 s among the operators. CONCLUSION: By utilization of IoT for surgery, surgical procedure could be "visualized." This will improve the safety on surgery such as optimal usage of surgical devices, proper use of electrocautery, and standardization of the surgical procedures.

INTRODUCTION: The clinical significance of laparoscopic cholecystectomy (LC) for acute cholecystitis in elderly patients aged 80 years or older has not been determined. This study aimed to investigate surgical outcomes of LC for acute cholecystitis in elderly patients compared to non-elderly patients. METHODS: Patients who underwent urgent LC for acute cholecystitis were enrolled. Older (≥80 years) and younger patients (<80 years) were compared for perioperative factors to assess surgical outcomes of LC. RESULTS: A total of 351 patients were included; 52 (14.8%) and 299 (85.2%) were categorized as older and younger, respectively. The older group had a significantly higher proportion of patients with concomitant physiological diseases than the younger group and a significantly higher ASA classification. No significant differences between the two groups were found in operation time, intraoperative blood loss, or conversion rate to open surgery. Incidence of postoperative complications and duration of postoperative hospital stay also were not significantly different between the two groups. CONCLUSION: Surgical outcomes of LC for acute cholecystitis in older patients are comparable to those in younger patients, which confirms the feasibility of LC for acute cholecystitis in elderly patients.

A 68-year-old man underwent a subtotal stomach-preserving pancreatoduodenectomy(SSPPD)for a distal bile duct carcinoma(BDC)pT3aN1M0, pStage â ¡B and adjuvant chemotherapy with gemcitabine. One year 7 months after the initial surgery, CT revealed a nodule with an increasing tendency in the left lung. As it was difficult to distinguish primary lung cancer from BDC lung metastasis, we performed a thoracoscopic left wedge resection. The histopathology of the resected specimen was BDC lung metastasis. In the follow-up with adjuvant chemotherapy with S-1 for 10 months, 2 nodules were found in the right lung, and we performed thoracoscopic right S6 segmentectomy. Eight months later, another nodule was found in the left lung, and we performed thoracoscopic left wedge resection. The histopathology was BDC lung metastasis for all the resected specimens. The patient is alive with no evidence of recurrence after 9 months of the latest surgery(4 years 11 months after the initial surgery). Although the standard treatment for metastatic recurrence of BDC is systemic chemotherapy, some cases treated with surgical resection had relatively good prognosis, such as the present case. Surgical resection might be feasible as a treatment option for metastatic recurrence of BDC.

Laparoscopic hepatectomy has gained popularity owing to its merits, such as low invasiveness and reduced bleeding. However, the efficacy of laparoscopic repeat hepatectomy(LRH)has not been confirmed. The aim of this study was to evaluate the feasibility and efficacy of LRH compared to that of open repeat hepatectomy(ORH). We performed 60 repeat hepatectomies from January 2011 to March 2019, of which 19 were LRH(Lap group)and 41 were ORH(Open group). This study retrospectively compared the patient characteristics and short-term outcomes of repeat hepatectomy between the Lap and Open groups. There were no significant differences in patient characteristics, except for the type of approach in the previous hepatectomy(p<0.01). The Lap group had lesser blood loss(median: 150 mL vs 355 mL, p<0.01)and shorter postoperative hospital stays(median: 8 days vs 11 days, p<0.01). There were no differences in operation time or severe postoperative complications. LRH is feasible and useful, providing good short-term outcomes.

A 65-year-old man visited our hospital for hepatocellular carcinoma(HCC)and underwent extended posterior sectionectomy. Eight months after the hepatic resection, follow-up computed tomography(CT)revealed a solitary, recurrent tumor in S4 of the liver, and transcatheter arterial chemoembolization and radiofrequency ablation were performed for the intrahepatic recurrence. After 12 postoperative months, follow-up CT demonstrated pulmonary metastases in S5 of the right lung and S10 of the left lung. Since there were no other metastases, the 2 metastatic lesions were resected using video-assisted thoracoscopic surgery(VATS). The resected tumors were histologically diagnosed as pulmonary metastases of HCC. Three years after the pulmonary resection, 3 additional pulmonary metastases were detected on CT in S3 and S10 of the right lung and S4 of the left lung. No other metastases were found. Bilateral VATSmetastasectomy was performed for the metastases. The tumors were diagnosed as pulmonary metastases of HCC on histological examination. One year and 8 months after the surgery, he was alive in a good condition, with no recurrences. The present case suggested that some patients with pulmonary metastasis of HCC can have long-term survival with surgical resection of the metastasis. Therefore, while systemic chemotherapy is generally considered the standard treatment for extrahepatic metastasis of HCC, surgical resection might be an option.

A 60s man underwent upper gastrointestinal endoscopy at a regular medical check-up without symptoms, which showed an ulcerative region in the duodenal ampulla, measuring 3 cm in diameter. He was diagnosed with poorly differentiated adenocarcinoma on biopsy and referred to our hospital. Abdominal contrast-enhanced CT scan revealed an enhanced-ulcerative tumor, measuring 3 cm, at the duodenal ampulla. After the preoperative diagnosis of adenocarcinoma of the duodenal ampulla, subtotal stomach-preserving pancreatoduodenectomy with regional lymph node dissection was performed. The final diagnosis was neuroendocrine carcinoma(NEC)of the duodenal ampulla. He has been alive for 9 years with no recurrences. NEC of the duodenal ampulla is rare, and its prognosis is poor. We report a case of long-term survival after resection of NEC of the duodenal ampulla.

A92 -year-old man was diagnosed with pancreatic cancer 14 years after undergoing distal gastrectomy for gastric cancer. His remnant stomach was fed by the cardiac branch of the left inferior phrenic artery, short gastric artery, and posterior gastric artery. We planned distal pancreatectomy(DP). Intraoperative indocyanine green(ICG)fluorography showed that the remnant stomach was perfused under the clamp of the splenic artery. We also confirmed that regional oxygen saturation (rSO2)of the remnant stomach was not decreased by the clamp. Based on the findings, we judged that blood flow in the remnant stomach was preserved at the clamp. We then performed DP with preservation of the remnant stomach. Postoperative complications associated with the remnant stomach were not observed. The patient is alive without any postoperative recurrences of pancreatic cancer or trouble associated with the remnant stomach 22 months after the surgery. This case suggested that ICG fluorography and rSO2 monitoring are useful to evaluate blood flow in the remnant stomach.

A 70s man presented with a solitary liver tumor measuring 4.5 cm on CT. On contrast-enhanced CT, the tumor appeared partly well-enhanced in the late phase, and the remaining part was enhanced in the early phase and washed out in the late phase. Contrast-enhanced MRIshowed fused multiple nodules, and the enhancement/washout pattern was clearer than that of the contrast-enhanced CT. The tumor showed a defective image in the hepatobiliary phase and a high signal on diffusionweighted imaging. Then, the tumor was diagnosed as hepatocellular carcinoma, and thus, left liver lobectomy was performed. On histological examination of the resected specimen, the tumor was found to be composed of uniform and small tumor cells with solid or trabecular growth fashion. On immunohistochemical staining, synaptophysin and chromogranin A positivity was noted, and the Ki-67 index was 14%. Finally, the tumor was diagnosed as a NET G2. Postoperatively, somatostatin receptor scintigraphy was performed to identify the primary site; however, no obvious primary site could not be identified, and thus a diagnosis of primary hepatic NET was made. Eighteen months postoperatively, the patient is alive without relapse. Preoperative diagnosis of primary hepatic NETs is difficult because NETs present various imaging findings and are rare. Moreover, no accurate preoperative diagnosis was reached in our case, suggesting the difficulty in the preoperative diagnosis of NETs.

A 69-year-old man was administered S-1/oxaliplatin/trastuzumab as induction chemotherapy for advanced gastric cancer (cT4b[liver, pancreas], N2M1(H1P0CYX), cStage IV). After 4 courses, because contrast-enhanced computed tomography showed remarkable reduction of the tumor, distal gastrectomy, partial hepatectomy, and radiofrequency ablation for the liver metastasis were performed. The patient was histopathologically diagnosed with gastric neuroendocrine carcinoma(NEC). S- 1/oxaliplatin/trastuzumab was continued after surgery; however, recurrence in the remnant liver was observed after 4 cours- es. For recurrence, cisplatin/irinotecan as first-line and paclitaxel/ramucirumab as second-line treatment were administered, but progression of liver metastasis and ascites due to peritoneal dissemination were observed. As third-line treatment, nivolumab was initiated. Ascites decreased after 3 courses, but after 2 more courses, progression of ascites, liver recurrence, and multiple metastasis in the lumbar vertebra were observed.

BACKGROUND: Intraductal papillary-mucinous neoplasms (IPMNs) are potentially malignant intraductal epithelial neoplasms that sometimes penetrate into other organs. To the best of our knowledge, no report has yet described a case with penetration into the spleen. We recently encountered a case of IPMN with penetration of the stomach and spleen that was successfully treated by total pancreatectomy. CASE PRESENTATION: A 70-year-old female visited our hospital with a complaint of fever and abdominal pain. Contrast-enhanced computed tomography (CT) revealed dilatation of the main pancreatic duct in the entire pancreas and penetration into the stomach and spleen. Upper gastrointestinal endoscopy revealed mucin extruding from four openings of the fistula in the stomach. No malignancy was detected based on cytology of the mucin. Inflammation markers and tumor markers (CEA, CA19-9) were elevated in the blood. The pre-operative diagnosis was IPMN of main pancreatic duct type penetrating into the stomach and spleen. A total pancreatectomy and splenectomy were performed, combined with distal gastrectomy including resection of the fistulas between the pancreas and stomach. No postoperative complications were noted. Histopathological examination of the resected specimen revealed atrophy of the pancreatic parenchyma, and the main duct of the pancreas was filled with mucin. Mucin-producing malignant tumor cells were detected in the epithelium of the main pancreatic duct with no signs of invasion. No malignancy was found at the fistulas between the pancreas and stomach or spleen. The patient was finally diagnosed with non-invasive intraductal papillary-mucinous carcinoma (IPMC) of main pancreatic duct type. Mechanical penetration was suspected as a mechanism of the penetration. The patient remained disease-free without evidence of recurrence more than 15 months after the operation. CONCLUSION: Though IPMNs sometimes penetrate into other adjacent organs, penetration into two organs, including the spleen, is rare. The rare case of IPMC penetrating into the stomach and spleen presented here was treated successfully by total pancreatectomy.
RESUMEN
AIMS: The reflux of duodeno-gastric contents into the remnant esophagus (gastric tube-esophageal reflux: GTER) is a significant issues in long-term esophageal cancer survivors after radical esophagectomy. We attempted endoscopic valve (funnel) creation for prevention for GTER using OverStitch endoscopic suturing system. METHODS: The OverStitch was mounted onto a standard double-channel endoscope. Under general anesthesia, the funnel creation was attempted by placing semi-full thickness sutures on the gastric wall, at 3 cm distal to the primary esophago-gastric anastomosis. The postoperative outcomes were also evaluated. RESULTS: In total, 4 sutures were needed and the operating time was 62 minutes without complication. The endoscopic and swallowing studies, as well as pH profile, were all improved postoperatively. The patient's quality of life was dramatically improved with complete disappearance of night-time reflux in spine position. CONCLUSIONS: Endoscopic antireflux funnel creation was feasible and safe. This procedure may become a useful treatment for patients with severe GTER after esophagectomy.
RESUMEN
We report a case of effective S-1 plus oxaliplatin (SOX) treatment for duodenal cancer with liver metastases. The patient was a 70-year-old female diagnosed with duodenal carcinoma that was unresectable because of liver metastasis(cT4N1M1, cStage IV in UICC 7th). She received SOX treatment(100mg/m / 2 of oxaliplatin on day 1 combined with 40 mg/day of S-1 twice daily on days 1-14, was repeated every 3 weeks). After 4 courses, a partial response was confirmed by computed tomography and no severe adverse events were observed. However, during the 5th courses, several new liver metastases were observed, so we changed to weekly paclitaxel treatment. This case suggests that SOX treatment may be an effective chemotherapy for advanced primary duodenal carcinoma.
