[Complete Obstruction of the Ascending Jejunal Limb due to Adhesion of the Y Loop after Total Gastrectomy].

A 43-year-woman who had undergone total gastrectomy for gastric cancer was admitted to our hospital because of lower abdominal pain 2 months after the operation. Abdominal computed tomography revealed an ascending jejunum dilation. Gastrointestinal endoscopy showed a complete obstruction in the ascending jejunum. A laparoscopic operation on the 14th hospital day revealed that the complete obstruction of the ascending jejunal limb was due to adhesion of the Y loop after total gastrectomy. She underwent division of the adhesion and was discharged on the 17th postoperative day.

[Internal Hernia after Distal Gastrectomy for Gastric Cancer Triggered by Retroperitoneal Recurrence].

A 77-year-male who had undergone distal gastrectomy with Roux-en-Y reconstruction received the tegafur/gimeracil/ oteracil adjuvant chemotherapy for about 1 year. 32 months after surgery, liver hilus lymph nodes and peritoneal recurrence were found. For obstructive jaundice, the metallic stent was implanted under double balloon-ERCP(DB-ERCP). He was treated 13 courses with SOX, preceded PTCD and re-implanted metallic stent for re-obstructive jaundice 52 months after the initial surgery. Although the jaundice was improved, he came to vomit after meal. Abdominal computed tomography revealed internal hernia. He had undergone the operation on the 8th hospital day. The hernial orifice was found in the mesentery defect due to peritoneal recurrence. He was able to eat after that operation but he was passed away POD-85 by the primary disease.

[A Case Report of Long-Term Survival after SOX Chemotherapy for Metastatic Ovarian Tumor of Gastric Cancer].

A 55-year-woman presented with abdominal fullness. An abdominal MRI disclosed ovarian and uterine tumors. Under the pathological diagnosis of Kruckenberg tumor, total hysterectomy and bilateral adenexectomy were performed. Gastrointestinal endoscopy disclosed type 3 on the greater curvature and anterior wall of the middle gastric body. The gastric cancer had a similar histology, which suggested the tumor origin and led to the diagnosis of c-stage IV. She received 6 courses of SOX chemotherapy. Staging laparoscopy revealed no peritoneal metastasis and negative cytodiagnosis of ascites. She underwent total gastrectomy with D2 lymphadenectomy. In May 2017, after S-1 chemotherapy, no metastasis to other organs was observed.

[A Case Report of Maintaining Continuous Ambulatory Peritoneal Dialysis after Total Gastrectomy for Perforated Gastric Cancer with ESD].

A 73-year-old man, receiving maintenance continuous ambulatory peritoneal dialysis(CAPD)was admitted to our hospital for chief complaining of heartburn. Gastrointestinal endoscopy disclosed 0- II a on the greater curvature of the upper gastric body. On further examination, the clinical diagnosis was defined as gastric cancer and c-stage I A(cT1aN0M0). The patient was recovered with conservative treatment from the perforated peritonitis after undergoing endoscopic submucosal dissection(ESD). Pathology revealed pT1b, INF b, UL(-), ly2, v0, pHM0, pVM0, for which he underwent total gastrectomy after changed to temporary hemodialysis(HD). On the 3rd postoperative day, blood examination showed WBC and CRP value of 16,100/mL and 20.282mg/dL, respectively. On the 6th postoperative day, nasal endoscopy revealed no anastomotic leakage and started oral take. The patient was discharged on the 20th postoperative day with changed to CAPD from the 7th postoperative day.

[The Efficiency of Postoperative Endoscopy for Anastomotic Leakage after Total Gastrectomy].

An 81-year-old man underwent total gastrectomy with Roux-en-Y reconstruction for cardiac cancer in our department. He developed high fever on postoperative day 3, and pathological examination showed WBC and CRP level of 12,000/mL and 29.983mg/dL, respectively. A diagnosis of anastomotic leakage was confirmed using enhanced abdominal CT scanning that demonstrated free air around the esophagojejunalanastomosis after totalgastrectomy. The drainage tube was replaced by a 12 Fr sump tube because of leakage on postoperative day 10. Nasal endoscopy performed on postoperative day 13 revealed anastomotic leakage from the sump tube in the abdominal cavity. Endoscopy performed on postoperative day 20 confirmed the anastomotic leakage as a fistula that allowed air to leak into the abdominal cavity. On postoperative day 28, the sump tube was removed and oralintake was started. In conclusion, postoperative endoscopy might be usefulfor the assessment and drainage of anastomotic leakage.

[A Case Report of Difficult Esophagojejunal Anastomosis for Multiple Primary Cancer of Malignant Lymphoma and Gastric Cancer].

A 54-year-old man presented with cervical lymph node swelling and exhibited high levels of sIL-2R. Enhanced cervical, chest, and abdominal CT scanning demonstrated swelling of the cervical, hilar, axilla, and abdominal lymph nodes. The patient was diagnosed with malignant, non-Hodgkin's lymphoma, B-cell, follicular lymphoma using biopsy of the cervical lymph nodes. Gastrointestinal endoscopy revealed II c like advanced tumor in the upper gastric body and post-wall area. He was diagnosed with primary multiple cancer comprising malignant lymphoma and gastric cancer. It was difficult to elevate the jejunum for esophagojejunal anastomosis due to the giant abdominal lymph node swelling. The patient received 5 courses of combination R-CHOP chemotherapy for malignant lymphoma. The swollen lymph nodes considerably reduced in size after chemotherapy. Totalgastrectomy with reconstruction using the Roux-en-Y method was performed for gastric cancer. Histopathological findings revealed pT3(SS), pN0, pH0, pP0, pStage I B. The patient achieved complete remission following another course of chemotherapy and involved field radiation therapy. At present, he shows no signs of recurrence of primary multiple cancer.

[Difficulty in Preoperative Diagnosis of Residual Gastric Cancer after Distal Gastrectomy for Duodenal Ulcer].

A 67-year-old man underwent distal gastrectomy via the Billroth Ⅱ method (B-Ⅱ) for a duodenal ulcer. He presented with appetite loss and nausea in May 2014. Gastrointestinal endoscopy revealed wall thickness around gastrojejunostomy and the gastric mucosal fold. Biopsy and re-biopsy revealed a group 2 tumor. Laparotomy for diagnosis was performed because of stenosis and tumor progression. Intraoperative frozen section examination revealed adenocarcinoma in the lymph nodes of the jejunum. Residual gastrectomy with reconstruction using the Roux-en-Y method was performed for residual gastric cancer. Histopathological findings revealed pT4a, pN0, pM1 for the tumor in the lymph nodes of the jejunum, pStage Ⅳ. A distorted gastrojejunostomy site and the presence of anastomotic strictures are important for the rapid diagnosis of residual gastric cancer.

[Two Cases of Small Bowel Obstruction Due to Postoperative Adhesions Treated with Laparoscopic Adhesiolysis].

We occasionally require surgical treatment for postoperative adhesion ileus. One patient had adhesion ileus 14 times in 14 years after distal gastrectomy and Billroth-Ⅰreconstruction for gastric cancer. He underwent laparoscopic adhesiolysis for a small bowel obstruction that adhered to the entire surface. Another patient experienced adhesion ileus 7 times in 1.5 years after distal gastrectomy and Billroth-Ⅰreconstruction for gastric cancer. He underwent laparoscopic adhesiolysis for a small bowel obstruction adhering to the scar and the retroperitoneum. After laparoscopic treatment, he underwent an open operation for ischemic colitis but no small bowel obstruction was found. Laparoscopic adhesiolysis was found to be useful in both cases.

[A Case of Gastrointestinal Stromal Tumor of the Stomach after Pancreatoduodenectomy].

We report a case of gastrointestinal stromal tumor of the stomach 17 years after pancreatoduodenectomy(PD). The patient was an 83-year-old man who had undergone PD for chronic pancreatitis at 65 years of age. Gastric endoscopy revealed a 2.5-cm gastric submucosal tumor on the lesser curvature of the stomach, which was the gastrojejunostomy site. As the gross appearance of the tumor showed ulceration at the top of the tumor, the patient underwent total gastrectomy and Roux-en-Y reconstruction. Histopathological examination demonstrated that the tumor was a GIST of the stomach. Currently, 5 years after surgery, no recurrence has been observed. Therefore, postsurgical care for a malignant disease may require a strict follow-up for a long time.

[A Successfully Treated Case of Central Venous Catheter-Related Suppurative Thrombophlebitis of the Right Jugular Vein to the Superior Vena Cava Associated with Esophageal Cancer].

A 63 year-woman was diagnosed with esophageal cancer (Mt. T4N2M0, c-Stage IIIC) after full examination. She underwent chemotherapy with 5-FU+CDDP (FP) through a central venous line (CV). She developed a fever of more than 40°C 15 days after the first course of chemotherapy. We removed the CV owing to suspicion of catheter-related bloodstream infection (CRBSI) and initiated treatment with antibiotics (CFPM). Even so, she experienced swelling from the right cervix to the precordium. We confirmed suppurative thrombophlebitis from the right jugular vein to the superior vena cava by CT and blood culture. After anti-coagulation therapy, venous thrombosis diminished and inflammation was cured. The patient continued to receive chemotherapy, underwent a bypass operation, and completed chemo-radiotherapy successfully while receiving anti-coagulation therapy.

Superior mesenteric artery syndrome after ileal pouch-anal anastomosis for colon cancer associated with ulcerative colitis: report of a case.

Superior mesenteric artery syndrome (SMAS) after a surgical operation is very rare. We experienced an extremely rare case of ileal pouch-anal anastomosis with subsequent development of SMAS requiring duodenojejunostomy. A 74-year-old Asian woman underwent total colectomy, ileal pouch-anal anastomosis (J-pouch), covering ileostomy, splenectomy, and distal pancreatectomy for treatment of descending colon cancer associated with ulcerative colitis. She complained of abdominal discomfort and vomiting 17 days postoperatively. Computed tomography (CT) revealed fluid collection at the pancreatic stump. We diagnosed a pancreatic fistula and performed CT-guided drainage. SMAS was thereafter diagnosed by contrast-enhanced CT, which revealed a narrow aortomesenteric angle of 36° and short aortomesenteric distance of 2 mm. The SMAS did not respond to conservative therapy. Finally, we performed duodenojejunostomy. This case illustrates that ileal pouch-anal anastomosis might induce relative stretching of the superior mesenteric artery and flatten it against the aorta, resulting in SMAS.

[A case report of residual gastric cancer 15 years after pancreatoduodenectomy with modified child's reconstruction].

A 75-year-old man underwent pancreatoduodenectomy for pancreatic cancer. He had presented with epigastralgia in June 2008. Gastrointestinal endoscopy revealed type 2 gastric cancer in the cardiac area. Enhanced abdominal CT scanning confirmed an enhanced mass in the cardiac area. Gastrectomy with Roux-en-Y reconstruction was performed for residual gastric cancer. Histopathological findings revealed, pT3(SS), pN0, pH0, pP0, pStageIIA. Single-agent TS-1 therapy was chosen as adjuvant chemotherapy but was changed to TS-1+CDDP because of CT-detected recurrence 3 months after the second operation. After a 6 month course of chemotherapy, complete reduction of the tumor was obtained.

[A case study of advanced gastric cancer patient treated with S-1+paclitaxel/lentinan].

A 47 -year-old male presented with gastric cancer, with right cervical and para-aortic lymph node metastases. The patient had not undergone a curative operation, but was treated with immunochemotherapy in combination with S-1 60 mg/m2(2 weeks administration and 2 weeks rest), paclitaxel 60 mg/m²(day 1, 8, 15), and Lentinan 2mg/body(day 1, 8, 15). After 3 courses of this treatment, no hot-spots were identified on cervical and para-aorta lymph nodes by PET-CT examination. We decided to perform total gastrectomy with D3 lymphadenectomy and Roux-en Y reconstruction. On histopathological examination, no malignancy was seen in the lymph nodes and the main tumor was judged to be grade 2. With this combined immunochemotherapy, the patient had a favorable outcome without side effects, which proved effective for far advanced gastric cancer.

Feasibility and accuracy of second-look laparoscopy after gastrectomy for gastric cancer.

BACKGROUND: A better method for detecting early peritoneal progression is needed. This study evaluated the feasibility and accuracy of second-look laparoscopy for patients with gastric cancer treated using systemic chemotherapy after gastrectomy. METHODS: Second-look laparoscopy was conducted for patients who had no clinical evidence of distant metastases but had peritoneal metastases or positive peritoneal cytology results without visible metastatic disease at initial surgery, patients who underwent systemic chemotherapy over a 6-month period after surgery, and patients who had no clinical evidence of disease based on imaging study after completion of primary chemotherapy. RESULTS: Between November 2004 and April 2008, 21 patients underwent second-look laparoscopy. At the initial surgery, 13 of these patients underwent total gastrectomy and 8 patients underwent distal gastrectomy. One or two sheets of adhesion barrier were received by 18 patients. The median interval between initial surgery and second-look laparoscopy was 9.8 months (range, 6.6-17.5 months). All second-look procedures were completed laparoscopically, and no patients required conversion to laparotomy. None of the 21 patients experienced postlaparoscopy complications. Whereas 12 patients showed no pathologic evidence of disease, 9 patients showed disease at second-look laparoscopy. There was a significant difference in median survival between the groups with negative and positive results (p = 0.017). The median survival for the negative group has not been determined. All the patients in the positive group received further chemotherapy while showing a good performance status (PS). Six patients were PS 0, and 3 patients were PS 1. The median survival time for this group was 10.1 months. CONCLUSIONS: Second-look laparoscopy was a safe and promising approach to reassessment of peritoneal disease for patients with gastric cancer. The incidence of complications was low, particularly in this group of patients, all of whom had undergone prior gastrectomy.

Surgical Control of a Primary Hepatic Carcinoid Tumor: A Case Report.

We report a primary hepatic carcinoid tumor occurring in a 47-year-old man. The patient consulted our hospital complaining of epigastralgia. Abdominal ultrasonography, computed tomography scanning, and magnetic resonance imaging showed a large mass in the right lobe of the liver. FDG-PET revealed 18F-FDG uptake by the right hepatic lobe. The tumor was a solid mass with cystic components, approximately 15 cm in diameter. We conducted an extended right lobectomy of the liver. The resected specimen was a solid tumor with cystic components and hemorrhagic lesion. Microscopic findings showed that the tumor cells had round nuclei and formed trabecular patterns. Immunohistologically, tumor cells were stained positive for chromogranin A, neuron specific enolase, CD56, and S-100. Careful examinations before and after the operation revealed no other possible origin of the tumor. Based on these findings, the tumor was diagnosed as a primary hepatic carcinoid. This is a report of a rare case of a primary hepatic carcinoid tumor with a discussion of several other relevant reports.

[Evaluation of the preserved function of the remnant stomach in pylorus preserving-gastrectomy by gastric emptying scintigraphy].

This study evaluated the preserved function of the remnant stomach by gastric emptying scintigraphy 1 year postoperatively in 49 patients who underwent pylorus-preserving gastrectomy (PPG), and it investigated whether this examination method is a useful tool for evaluation. The residual stomach function was classified as rapid, intermediate, and delayed emptying types according to gastric emptying curves. Then, the relationships were examined between the gastric emptying types and postprandial symptoms, food intake status, body weight changes, and endoscopic findings. Seventy-three percent of the PPG patients were classified as belonging to the intermediate emptying type, and the remainder (27%) to the delayed type. The frequencies of complaints such as epigastric fullness, nausea, and vomiting were high in the delayed emptying-type patients. The intermediate emptying-type patients consumed larger amounts of food and gained more weight than the delayed emptying-type patients. In conclusion, gastric function was evaluated by gastric emptying scintigraphy in PPG patients. This method might be useful not only for evaluating the motor function of the remnant stomach, but also for predicting postoperative status. Although PPG is a function-preserving operation, it should be considered that a quarter of the patients showed delayed emptying type which related to poor quality of life.

Assessment of the preserved function of the remnant stomach in pylorus-preserving gastrectomy by gastric emptying scintigraphy.

BACKGROUND: This study evaluated the preserved function of the remnant stomach by gastric emptying scintigraphy in patients who underwent pylorus-preserving gastrectomy (PPG), and it investigated whether this examination method is a useful tool for evaluation. MATERIALS AND METHODS: The residual stomach function was evaluated by gastric emptying scintigraphy in 45 patients with early gastric cancer who had undergone PPG. Function was classified as rapid, intermediate, and delayed emptying types according to gastric emptying curves. Then, the relationships were examined between the gastric emptying types and postprandial symptoms, food intake status, body weight changes, and endoscopic findings. RESULTS: Seventy-three percent of the PPG patients were classified as belonging to the intermediate emptying type, and the remainder to the delayed emptying type. The frequencies of complaints such as epigastric fullness, nausea, and vomiting were high in the delayed emptying-type patients. The intermediate emptying-type patients consumed larger amounts of food and gained more weight than the delayed emptying-type patients. It was difficult to estimate gastric emptying function from endoscopic findings. CONCLUSIONS: Gastric function was evaluated by gastric emptying scintigraphy in PPG patients. This method might be useful not only for evaluating the motor function of the remnant stomach, but also for predicting postoperative status.

Posterior esophagopexy with dome formation to prevent reflux in interposed jejunal pouch reconstruction after total gastrectomy.

Jejunal pouch interposition (JPI) reconstruction after total gastrectomy has proven effective for improving postoperative quality of life; however, evaluation of bile reflux into the esophagus shows that the reflux of digestive juice is not sufficiently prevented. Therefore, in addition to the conventional reconstruction technique, we created an artificial pouch to prevent the reflux of digestive juice from the jejunal pouch into the esophagus, and performed a new surgical technique based on the Hill's posterior gastropexy. No postoperative complications were observed and the postoperative measurement showed a decrease in the duration of bile reflux into the esophagus. Thus, our new surgical procedure seems to effectively prevent bile reflux.

Role of pyloroplasty after proximal gastrectomy for cancer.

BACKGROUND/AIMS: The necessity of pyloroplasty as a drainage procedure after proximal gastrectomy remains controversial in terms of the postoperative quality of life. The aim of this retrospective study was to evaluate whether pyloroplasty is necessary after proximal gastrectomy. METHODOLOGY: Thirty-five patients who underwent proximal gastrectomy with jejunal interposition between 1993 and 2000 were studied. They were divided into two groups: Group A, jejunal interposition without pyloroplasty (n=17); Group B, jejunal interposition with pyloroplasty (n=18). The subjects were interviewed and examined to assess their symptoms, food intake and body weight at 6, 12, and 24 months after the operation. Endoscopy and a radioisotope gastric emptying test were performed one year postoperatively. RESULTS: A low incidence of epigastric fullness, nausea, and vomiting and a high frequency of patients with greater than 80% of pre-illness food intake were found in Group B. A high recovery of bodyweight was also achieved in Group B. On the other hand, a high incidence of reflux gastritis or bile regurgitation was found in Group B. Gastric emptying was significantly delayed in Group A. CONCLUSIONS: Pyloroplasty as a drainage procedure after proximal gastrectomy is necessary in terms of the clinical symptoms, dietary intake, recovery of body weight, or gastric emptying.

Further evidence that epidermal growth factor enhances the intestinal adaptation following small bowel transplantation.

Recent reports indicate that epidermal growth factor (EGF) plays a crucial role for graft adaptation in rat model of small bowel transplantation (SBT). The administration of EGF enhances intestinal cell proliferating rate and the recovery of mucosal structure. However, the effect of EGF on biological functions including glucose absorption in intestinal graft remains to be elucidated. SBT was performed in the two-step procedure. On the first step, intestinal graft (30-cm jejunum) from Brown Norway rats was exteriorized through abdominal wall as a Thiry-Vella loop in recipient Lewis rats for one week. On the second surgery (POD 7), recipient jejunum was replaced orthotopically by the graft, and transplanted rats were treated intraperitoneally with EGF or its vehicle for 3 days. Analyses of histology and biological functions in the graft were done at POD 14. EGF increased both levels of villus height and crypt depth in the graft of transplanted groups. EGF enhanced the glucose absorption as well as the induction of sodium glucose cotransporter 2- to 3-fold in transplanted groups. Further, EGF stimulated the activities of disaccharidase (maltase and sucrase) and the induction of dipeptide cotransporter. These results demonstrate that EGF enhances the structural and functional adaptation of intestinal grafts after SBT. EGF may be useful therapy for patients following intestinal transplantation.
