[A Case of Late Recurrence of Gastric Cancer Over Ten Years Post Gastrectomy].

A 72-year-old woman underwent a low anterior resection of the rectum and a total hysterectomy with a bilateral salpingo- oophorectomy simultaneously for rectal and ovarian cancer, respectively. The pathological diagnosis was a moderately differentiated adenocarcinoma of the rectum with some poorly differentiated components signet-ring cell components. A mucinous adenocarcinoma, with similar characteristics as that in the rectum, was found in the ovary. Intraoperative findings revealed no direct invasion between the rectum and ovaries, with no peritoneal dissemination. She was, therefore, diagnosed with synchronous double cancer. The rectal cancer was pT3N0M0, Stage Ⅱ and the ovarian cancer pStage Ⅰ. Adjuvant chemotherapy with capecitabine was performed for high-risk Stage Ⅱ rectal cancer. At 3.5 years after surgery, her CA19-9 level was high and pleural dissemination and para-aortic lymph node metastasis were confirmed on thoracoabdominal CT. Twelve years after the gastrectomy for gastric cancer, a comparison of the pathological specimens of her stomach at that time with the current pathological specimens revealed that the rectal and ovarian tumors were metastases of gastric cancer and that the current recurrence was a late recurrence of this disease. Late recurrence after gastrectomy, especially 10 years or more after surgery, is extremely rare.

[Laparoscopic Distal Gastrectomy for Elderly Patients with Advanced Gastric Cancer and Gastric Outlet Obstruction - A Case Report].

A 90-year-old female patient was admitted to our hospital with a chief complaint of vomiting.Gastroscopy revealed type 3 gastric cancer and gastric outlet obstruction(GOO).Abdominal computed tomography revealed thickening of the antral wall and suggested the presence of 3 perigastric lymph node metastases, but there was no ascitic fluid or distant metastasis.The clinical diagnosis was T4a(SE)N2H0CYXP0M0, Stage III B, according to the Japanese Classification of Gastric Carcinoma.Her general conditions including kidney and cardiac function were good, we considered that she was able to tolerate radical distal gastrectomy.We planned laparoscopic distal gastrectomy(LDG)and D2 lymphadenectomy after getting sufficient informed consent.The patient experienced an uneventful post-operative recovery, and was discharged in good health 11 days after surgery.

[Early Liver Metastases after Curative Surgery for Stageâ Gastric Cancer with Neuroendocrine Differentiation-A Case Report].

An 87-year-old male patient was admitted to our hospital with a chief complaint of vomiting. Gastroscopy revealed Type 0-Ⅱc+Ⅱa tumor at the posterior wall in the middle third of the stomach. A biopsy indicated moderately differentiated adenocarcinoma. Abdominal CT revealed no lymph node or distant metastases. The clinical diagnosis was cT2(MP), N0, M0, cStage Ⅰ. Laparoscopic distal gastrectomy with D2 lymphadenectomy was performed. The pathological findings revealed moderately differentiated adenocarcinoma containing synaptophysin, chromogranin A, and CD56-positive tumor cells. He was then diagnosed with adenocarcinoma with neuroendocrine differentiation. The pathological diagnosis was pT2(MP), pN0, M0, pStage ⅠB. MRI revealed multiple liver metastases 5 months postoperatively. S-1 alone chemotherapy was started, and the patient showed partial response(PR)after 3 courses, according to the Response Evaluation Criteria in Solid Tumor (RECIST).

[Invasive Micropapillary Carcinoma of the Colon That Was Difficult to Diagnose Preoperatively].

A 73-year-old man was admitted with sigmoid colon diverticulitis. Although a biopsy did not indicate malignancy, the sigmoid colon was completely obstructed following conservative treatment. After sigmoidectomy, the histopathological findings revealed a well-differentiated adenocarcinoma localized to the mucosal surface; invasive micropapillary carcinoma (IMPC)accounting for>95% of the tumor volume spread extensively below the submucosal layer. IMPC is highly malignant and difficult to diagnose preoperatively, possibly due to the presence of poorly differentiated histological sub-types in the deepest portions of the tumor.

[A Case of Rectal Cancer Presenting with Schistosomiasis Japonica Eggs].

A 87-year-old man had used to live in Shizuoka Prefecture. He got colonoscopy due to melena, and a type 1 tumor about 3 cm was detected in the rectum. He was diagnosed with rectal cancer. We performed a laparoscopic low anterior resection with lymphadenectomy. Histopathological findings shows tub1, pSM(7mm), med, INF a, ly1, v0, pPM0, pDM0, pN0(0/7), T1bN0M0, Stage I . Schistosoma japonica eggs were seen in submucosal of the rectum not around the tumor but also normal tissue. The eggs embolized microvessels. It has been 5 year since the operation, the patient has survived without recurrence.

[Esophagogastric Junction Cancer Resection with Bilateral Adrenal Metastasis - A Case Report].

The patient was a 64-year-old man with esophagogastric junction cancer. We performed right thoracotomy-laparotomy for lower esophageal and cardiac gastric resection, D2 lymphadenectomy, and reconstruction of a gastric tube in October 2011. Histopathology confirmed T4aN1M1(LYM), Stage IV cancer(Japanese Classification of Gastric Carcinoma, 14th edition) with R0 resection. Because of preexisting alcoholic cirrhosis, postoperative chemotherapy was not an option. In March 2014, we performed left adrenalectomy for left adrenal metastasis, and in December 2014, we performed right adrenalectomy for metastasis to the right adrenal gland. The patient was prescribed 20mg/day of hydrocortisone postoperatively. Survival from the right adrenalectomy was 2 years and 2 months, and survival from the first operation was 5 years and 4 months, without recurrence. This case of esophagogastric junction cancer resection with bilateral adrenal metastasis is rare, with only one previously reported case in Japan.

[Outcomes of Staging Laparoscopy in Eight Patients with Positive Peritoneal Washing Cytology after S-1 Administration].

AIM: The aim of this study was to clarify the clinical outcomes of staging laparoscopy(SL)for patients with positive peritonealwashing cytology(CY1P0)after S-1 administration. PATIENTS AND METHODS: Since 2007, eight CY1P0 patients who underwent SL after S-1 administration were enrolled. S-1 was administered according to the ACTS-GC and SL was performed after 8 courses of S-1 treatment. RESULTS: SL was ended with adequate observation of intra-abdominalcavity in allthe patients with a median time of 68 minutes(range: 52-76 minutes). The timing of SL was after 8 courses of S-1 administration in 6 patients, after 11 courses in 1, and 12 courses in 1. Based on the SL results, CY0P0 was attained in 6 patients; CY1P0, in 1 and CY1P1, in 1. For the 6 patients who attained CY0P0, S-1 administration was completed. For the 2 patients who attained CY1P0 and CY1P1, chemotherapy was continued. Only 1 of the patients who attained CY0P0 had peritoneal recurrence 3 months after completion of S-1 administration. CONCLUSION: When CY0P0 is detected by using SL, S-1 administration may be completed. More cases need to be studied to determine the suitable courses or timing of S-1 administration for CY0P0 patients.

Perforated Carcinoma in the Gastric Remnant: A Case of Conservative Treatment Prior to Successful Curative R0 Resection.

An 80-year-old man who had undergone distal gastrectomy and Billroth-II gastrojejunostomy 38 years previously, for a benign gastric ulcer, was diagnosed with remnant gastric cancer based on upper gastrointestinal endoscopy findings. He presented at our emergency department with acute-onset epigastric pain due to perforated remnant gastric cancer. Conservative medical management was selected, including nasogastric tube insertion, antibiotics, and proton pump inhibitors, because his peritonitis was limited to his epigastrium and his general condition was stable. Twenty-one days after the perforation occurred, curative total remnant gastrectomy and D2 lymphadenectomy were performed. Adhesion between the lateral segment of the liver and the dissected lesser curvature of the gastric remnant may have contributed to the peritonitis in this case, which was limited to the epigastrium. This is the first report of perforated remnant gastric cancer in which conservative treatment was effective prior to curative resection. The protocol reported here may be of use to other clinicians who may encounter this clinical entity in their practices.

A case report of successful removal of multiples sewing needles in the gastrointestinal tract and pancreas using intraoperative C-arm fluoroscopy.

BACKGROUND: Most ingested foreign bodies pass uneventfully through the digestive tract without any major disturbances. OBJECTIVES: We reports a rare case of successful localization and surgical removal of needles in the gastrointestinal tract using C-arm fluoroscopy intraoperatively. CASE REPORT: A 46year old female, a non-hospitalized psychiatric patient, presented with acute abdominal pain. Imaging showed 16 needles all over the digestive tract. C arm fluoroscopy was used to successfully localize and remove all of the needles intraoperatively. One needle was withdrawn from the pancreas manually without pancreatic resection. DISCUSSION: It is estimated that up to 10-20% cases require endoscopic removal and 1% cases with the presence of obstruction or perforation necessitate surgical interventions [1-4] (Hsieh et al., 2005; Anderson and Dean, 2011; Cheng and Tam, 1999; Ricci et al., 2014). Migration to the pancreas extremely rare [5,6] (Toyonaga et al., 2001; Yasuda et al., 2010). Timely diagnosis can be difficult [7] (Tsui and Mossey, 1997). CT scan is a modality of choice to preoperatively locate the foreign body [8] (Takada et al., 2000). We herein successfully localized and removed 15 needles using C-arm fluoroscopy intraoperatively. It is extremely useful to accurately detect radiopaque foreign bodies. On the basic of findings on CT, treatment of choice such as endoscopic removal or surgical intervention may be attempted. CONCLUSIONS: CT scan is a modality of choice to preoperatively locate the foreign body. Sharp-pointed objects should be removed even if the patient is asymptomatic as the increased mortality and the risk of related complications. Intraoperative C-arm fluoroscopy is a feasible, cost-effective modality with real-time image to accurately detect multiple radiopaque objects especially when they are disseminating throughout the digestive tract.

A Case of Laparoscopic Resection for Carcinoma of the Gastric Remnant following Proximal Gastrectomy Reconstructed with Jejunal Interposition.

A 72-year-old Japanese man had a history of proximal gastrectomy for early gastric cancer located in the upper third of the stomach in 2007. Our usual treatment strategy for early gastric cancer in the upper third of the stomach in 2007 was open proximal gastrectomy reconstructing by jejunal interposition with a 10 cm single loop. Upper gastrointestinal fiberscopy for annual follow-up revealed a type 0-IIc-shaped tumor with ulcer scar, 4.0 cm in size, located in the gastric remnant near the jejunogastrostomy. A clinical diagnosis of cancer of the gastric remnant, clinical T1b(SM)N0M0, Stage IA, following the proximal gastrectomy was made and a laparoscopic approach was selected because of the cancer's early stage. Remnant total gastrectomy with D1 plus lymphadenectomy was carried out with five ports by a pneumoperitoneal method. Complete resection of the reconstructed jejunum was undergone along with the jejunal mesentery. Reconstruction by the Roux-en-Y method via the antecolic route was selected. Total operative time was 395 min and blood loss was 40 mL. Our patient was the first successful case of resection for carcinoma of the gastric remnant following proximal gastrectomy reconstructed with jejunal interposition in a laparoscopic approach.

Totally laparoscopic gastrectomy for early gastric cancer accompanied by huge hiatal hernia: A case report.

We herein present a case in which we used a totally laparoscopic approach for early gastric cancer accompanied by a huge hiatal hernia. An 80-year-old Japanese woman was referred with a chief complaint of dysphagia. A clinical diagnosis of early gastric cancer, T1b (SM) N0M0, stage IA, accompanied by hiatal hernia, was made. Distal gastrectomy with D1 plus lymphadenectomy was carried out. After the gastrectomy, the hernial sac was excised and the hernial orifice was closed. Reconstruction using the Roux-en-Y method was selected. The postoperative course was uneventful and she was discharged on postoperative day 10.

[Multidisciplinary Treatment for a Patient with Primary Malignant Melanoma Arising from the Stomach].

A 61-year-old woman was referred to our hospital with the complaint of severe dysphagia. Upper gastrointestinal endoscopy revealed an elevated tumor with an irregular surface located in the upper third of the stomach, and malignant melanoma was confirmed by biopsy specimens. Abdominal CT scan findings revealed that the tumor was invading the lateral segment of the liver and crus of the diaphragm. Total gastrectomy was combined with resection of the lateral segment of the liver and the crus of the diaphragm, and D2 lymphadenectomy and reconstruction by the Roux-en-Y method were carried out. Because of positive peritoneal washing cytology, monotherapy with dacarbazine, and combination therapy, including dacarbazine, nimustine hydrochloride, cisplatin, and tamoxifen citrate, were administered for treating the residual tumor. The patient died from peritoneal relapse 146 days after the initial surgery. Primary malignant melanoma arising from the stomach is reported as an extremely rare disease with a poor prognosis. In our case, multidisciplinary treatment including surgery and chemotherapy was insufficient to achieve long-term survival in a highly advanced malignant melanoma arising from the stomach.

[Effectiveness of chemoradiotherapy for a patient with local recurrence of advanced gastric cancer followed by curable gastrectomy].

We report here the effectiveness of chemoradiotherapy for a patient with local recurrence followed by curable gastrectomy. A 57-year-old man presented with a history of total gastrectomy with distal pancreatectomy and splenectomy, D2 lymphadenectomy, and Roux-en-Y reconstruction for advanced gastric cancer arising from the cardia. Esophageal intramural metastasis and lymph node metastasis around the right recurrent nerve were detected by chest-abdominal computed tomography and gastrointestinal endoscopy 27 months after the initial gastrectomy. Stable disease was achieved following 7 courses of chemotherapy using S-1 plus CDDP. Concurrent chemoradiotherapy including administration of S-1 and radiation of total 50 Gy (2 Gy/25 Fr) was selected for local tumor control. The patient was not able to eat solid food because of esophageal stenosis from regrowth of intramural metastasis of the esophagus 60 months after the chemotherapy. A WallFlex™ Duodenal Stent was placed to improve the dysphagia 67 months after chemotherapy. The patient died from recurrence of gastric cancer 69 months after completion of the initial chemotherapy and 2 months after the stent insertion.

[Multidisciplinary therapy for 3 patients with lymph node recurrence after curative gastrectomy].

We report multidisciplinary treatment of 3 patients with lymph node recurrence after curative gastrectomy. Case 1: A 71- year-old woman had a history of distal gastrectomy with D2 lymphadenectomy for the treatment of advanced gastric cancer. Para-aortic lymph node metastasis was observed 36 months after surgery. Complete response( CR) was achieved after concurrent chemoradiotherapy with S-1 plus radiation. Case 2: A 51-year-old man had a history of total gastrectomy with D2 lymphadenectomy for the treatment of advanced gastric cancer. Right cervical lymph node metastasis was observed 48 months after surgery. CR was achieved after concurrent chemoradiotherapy with S-1 plus radiation. Case 3: A 68-year-old man had a history of distal gastrectomy with D2 lymphadenectomy followed by neoadjuvant chemotherapy for the treatment of advanced gastric cancer. CR was achieved after sequential treatment with irinotecan( CPT-11) plus cisplatin( CDDP), radiation, and 5-fluorouraci(l 5-FU) plus Leucovorin therapy for lymph node recurrence near the head of the pancreas. These cases suggest that the combination of systemic chemotherapy and local radiation therapy might be effective for the treatment of lymph node recurrence in patients with gastric cancer.

[Therapeutic strategy for gastric cancer with positive peritoneal lavage cytology without peritoneal dissemination].

We analyzed the prognosis of patients with positive lavage cytology, excluding other unresectable factors.From 2002 to 2008, 76 advanced gastric cancer patients positive for malignant cells(CY1)were investigated for our study.There were 60 patients undergoing gastric cancer surgery.Sixteen patients were treated by chemotherapy only. The MST of the chemotherapy group was 427 days, and that of the gastrectomy group was 442 days, although this was not statistically significant.The multimodality therapy group undergoing gastrectomy and chemotherapy consisted of 42 patients.The MST of this group was 647 days.In the multimodality therapy group, there were 28 patients undergoing chemotherapy using S-1.The MST of this group was relatively better(1, 249 days).CY1 appeared to be a worse prognostic factor, but P0CY1 survival was better than in P1. As a therapeutic strategy for gastric cancer with positive peritoneal lavage cytology, multimodality therapy with gastrectomy and chemotherapy using S-1 may be effective.
