RESUMEN
BACKGROUND: Pancreaticojejunal (PJ) anastomosis occasionally fails several months after pancreaticoduodenectomy (PD) with Child reconstruction and can ultimately result in a late-onset complete pancreaticocutaneous fistula (Lc-PF). Since the remnant pancreas is an isolated segment, surgical intervention is necessary to create internal drainage for the pancreatic juice; however, surgery at the previous PJ anastomosis site is technically challenging even for experienced surgeons. Here we describe a simple surgical procedure for Lc-PF, termed redo PJ anastomosis, which was developed at our facility. METHODS: Between January 2008 and December 2020, six consecutive patients with Lc-PF after PD underwent a redo PJ anastomosis, and the short- and long-term clinical outcomes have been evaluated. The abdominal cavity is carefully dissected through a 10-cm midline skin incision, and the PJ anastomosis site is identified using a percutaneous drain through the fistula tract as a guide, along with the main pancreatic duct (MPD) stump on the pancreatic stump. Next, the pancreatic stump is deliberately immobilized from the dorsal plane to prevent injury to the underlying major vessels. After fixing a stent tube to both the MPD and the Roux-limb using two-sided purse-string sutures, the redo PJ anastomosis is completed using single-layer interrupted sutures. Full-thickness pancreatic sutures are deliberately avoided by passing the needle through only two-thirds of the anterior side of the pancreatic stump. RESULTS: The redo PJ anastomosis was performed without any intraoperative complications in all cases. The median intraoperative bleeding and operative time were 71 (range 10-137) mL and 123 (range 56-175) min, respectively. Even though a new mild pancreatic fistula developed postoperatively in all cases, it could be conservatively treated within 3 weeks, and no other postoperative complications were recorded. During the median follow-up period of 92 (range 12-112) months, no complications at the redo PJ anastomosis site were observed. CONCLUSIONS: This research shows that the redo PJ anastomosis for Lc-PF we developed is a safe, feasible, and technically no demanding procedure with acceptable short- and long-term clinical outcomes. This procedure has the potential to become the preferred treatment strategy for Lc-PF after PD.

BACKGROUND: Combined resection of the right hepatic artery (RHA) is sometimes required to achieve complete resection of hilar cholangiocarcinoma. The present study aimed to evaluate the feasibility of combined resection and subsequent reconstruction by continuous suture of the RHA during left hepatectomy for cholangiocarcinoma. MATERIALS AND METHODS: We retrospectively compared the outcomes after left hepatectomy with biliary reconstruction for cholangiocarcinoma between patients with and without RHA resection and reconstruction. RESULTS: Of the 25 patients who underwent left hepatectomy combined with biliary reconstruction, eight patients (32%) underwent combined resection and reconstruction of the RHA (AR group). The demographic characteristics were not different between the AR and non-AR groups. The amount of intraoperative bleeding was significantly greater in patients with AR (2350 mL vs. 900 mL, p = 0.017). The prevalence of early complications above grade III in Clavien-Dindo classification and late complications were not significantly different between the AR and non-AR groups. In the AR group, complications directly associated with AR, such as thrombosis or reanastomosis, were not observed. On Kaplan-Meier analysis, recurrence-free survival (p = 0.618) and overall survival (p = 0.803) were comparable between the two groups despite the advanced T stages in the AR group. CONCLUSIONS: Combined resection and subsequent reconstruction of the RHA during left-sided hepatectomy is a feasible treatment alternative for cholangiocarcinoma.

BACKGROUND Epstein-Barr virus (EBV) and Helicobacter pylori (HP) infections are associated with gastric carcinoma (GC). We present a thought-provoking case of multiple GCs associated with EBV and HP infections. CASE REPORT HP infection was incidentally detected in an asymptomatic 60-year-old man. Upper endoscopy revealed gastric "kissing" ulcers. The lesions were located in the body of the stomach and measured 25 and 27 mm, respectively. They were diagnosed on pathology as moderately differentiated tubular adenocarcinoma. Imaging revealed no enlarged lymph nodes or distant metastatic lesions. Distal gastrectomy with lymphadenectomy was performed and surgical cure was obtained. The multiple GCs were categorized on pathology as infß ly0 v0 pT1b(SM)UL1N0M0H0P0CY0 pStage IA according to the Japanese classification and as T1bN0M0 Stage IA according to the tumor, node, metastasis classification. Pathological examination revealed remarkable lymphocytic infiltration into the stroma, as shown by in situ hybridization of EBV. These lymphocytic infiltrations were observed only at the sites of GC. In the immunohistochemical examination, in situ hybridization of EBV was positive for EBV-encoded small ribonucleic acid. The patient's postoperative course was uneventful. Hence, an unexpected relationship between EBV infection and multiple GCs was suggested by pathology. Quantitative determination of EBV DNA in peripheral blood was normal postoperatively. Adjuvant chemotherapy was not recommended. HP eradication therapy was successful. The patient remained asymptomatic and developed no recurrence or metastasis for 3 years after surgery. CONCLUSIONS This thought-provoking case suggests that coinfection with EBV and HP increases GC occurrence.

When performing pancreaticoduodenectomy with resection of the confluence of the superior mesenteric vein and portal vein, division of the splenic vein may cause sinistral portal hypertension resulting in gastrointestinal bleeding, splenic congestion, and hypersplenism. To prevent these adverse events, it is important to intentionally decompress the splenic vein. This report is of a 68-year-old woman with stage IA carcinoma of the head of the pancreas who survived for more than six years following tumor resection and pancreaticoduodenectomy and distal splenorenal shunt. A 68-year-old woman was diagnosed with carcinoma of the head of the pancreas that involved the confluence of the superior mesenteric vein, portal vein, and splenic vein. No unresectable cancer sites or distant metastases were detected. Pancreaticoduodenectomy with resection of the confluence of the superior mesenteric vein and portal vein was performed. The superior mesenteric vein and portal vein were anastomosed in the end-to-end fashion, and the remnant splenic vein was anastomosed to the superior aspect of the left renal vein in the end-to-side fashion. At 22 months after the initial surgery, the patient underwent partial lung resection for a metachronous lung metastasis. For 6 years after the initial surgery, the venous reconstructions have maintained their patency without any obstruction of splenic venous flow, and the patient has remained in good health without further metastases or recurrences. This case has shown the importance of early diagnosis of carcinoma of the head of the pancreas, as appropriate and timely surgical management can result in good outcome. This patient responded well and remains alive six years following pancreaticoduodenectomy and preservation of the spleen with the use of a distal splenorenal shunt.
RESUMEN
BACKGROUND: Although arterial hemorrhage after pancreaticoduodenectomy (PD) is not frequent, it is fatal. Arterial hemorrhage is caused by pseudoaneurysm rupture, and the gastroduodenal artery stump and hepatic artery (HA) are frequent culprit vessels. Diagnostic procedures and imaging modalities are associated with certain difficulties. Simultaneous accomplishment of complete hemostasis and HA flow preservation is difficult after PD. Although complete hemostasis may be obtained by endovascular treatment (EVT) or surgery, liver infarction caused by hepatic ischemia and/or liver abscesses caused by biliary ischemia may occur. We herein discuss therapeutic options for fatal arterial hemorrhage after PD. AIM: To present our data here along with a discussion of therapeutic strategies for fatal arterial hemorrhage after PD. METHODS: We retrospectively investigated 16 patients who developed arterial hemorrhage after PD. The patients' clinical characteristics, diagnostic procedures, actual treatments [transcatheter arterial embolization (TAE), stent-graft placement, or surgery], clinical courses, and outcomes were evaluated. RESULTS: The frequency of arterial hemorrhage after PD was 5.5%. Pancreatic leakage was observed in 12 patients. The onset of hemorrhage occurred at a median of 18 d after PD. Sentinel bleeding was observed in five patients. The initial EVT procedures were stent-graft placement in seven patients, TAE in six patients, and combined therapy in two patients. The rate of technical success of the initial EVT was 75.0%, and additional EVTs were performed in four patients. Surgical approaches including arterioportal shunting were performed in eight patients. Liver infarction was observed in two patients after TAE. Two patients showed a poor outcome even after successful EVT. These four patients with poor clinical courses and outcomes had a poor clinical condition before EVT. Fourteen patients were successfully treated. CONCLUSION: Transcatheter placement of a covered stent may be useful for simultaneous accomplishment of complete hemostasis and HA flow preservation.
RESUMEN
INTRODUCTION AND IMPORTANCE: The most common liver malignancies are hepatocellular carcinoma, intrahepatic cholangiocarcinoma, and metastatic tumors. Hepatocellular carcinoma and intrahepatic cholangiocarcinoma may invade the portal vein (PV). An association between diffuse large B-cell lymphoma (DLBCL) and primary biliary cholangitis (PBC) remains unclear. We herein report a thought-provoking case of a difficult-to-diagnose liver tumor with PV thrombosis in a PBC patient. PRESENTATION OF CASE: A 66-year-old woman had PBC, systemic sclerosis, diabetes, and osteoporosis. A solitary liver tumor accompanied by macrovascular thrombosis in the PV was detected incidentally. Based on dynamic imaging findings, we considered the tumor to be intrahepatic cholangiocarcinoma, and right lobectomy with lymphadenectomy was performed. Unexpectedly, pathological assessment made a definitive diagnosis of DLBCL that did not invade the vessels and bile duct. In fluorine-18-fluorodeoxyglucose positron emission tomography, abnormal accumulations were clearly observed in the breast tissue and peritracheal, parasternal, mediastinal, and pericardial lymph nodes. The patient achieved complete remission after systemic chemotherapy, and there has been no recurrence 3 years after surgery. CLINICAL DISCUSSION: Primary lymphoma in the liver is rare, and we did not consider our patient's tumor as primary liver lymphoma. Our case actually showed no tumor thrombosis in the PV. Although autoimmune disorders may increase the risk of non-Hodgkin's lymphoma, an association between DLBCL and PBC is still unclear, and we must remember that DLBCL may develop rarely in a PBC patient. CONCLUSION: Our case report provides a timely reminder for clinicians and surgeons in the fields of hepatology and hematology.
RESUMEN
BACKGROUND Advanced malignancies in the lower abdomen easily invade the retroperitoneal and pelvic space and often metastasize to the paraaortic and pelvic lymph nodes (LNs), resulting in paraaortic and/or pelvic tumor (PPT). CASE REPORT A total of 7 cases of aggressive malignant PPT resection and orthotopic replacement of the abdominal aorta and/or iliac arteries with synthetic arterial graft (SAG) were experienced during 16 years. We present our experience with aggressive resection of malignant PPTs accompanied by arterial reconstruction with SAG in detail. The primary diseases included 2 cases endometrial cancer and 2 cases of rectal cancer, and 1 case each of ovarian carcinosarcoma, vaginal malignant melanoma, and sigmoid cancer. Surgical procedures are described in detail. Briefly, the abdominal aorta and iliac arteries were anastomosed to the SAG by continuous running suture using unabsorbent polypropylene. Five Y-shaped and 2 I-shaped SAGs were used. This en bloc resection actually provided safe surgical margins, and tumor exposures were not pathologically observed in the cut surfaces. Graphical and surgical curability were obtained in all cases in which aggressive malignant PPT resections were performed. The short-term postoperative course of our patients was uneventful. From a vascular perspective, the SAGs remained patent over the long term after surgery, and long-term oncologic outcomes were satisfactory. CONCLUSIONS To our knowledge, this case series is the first report of aggressive malignant PPT resection accompanied by arterial reconstruction with SAG. This procedure is safe and feasible, shows curative potential, and may play a role in multidisciplinary management of malignant PPTs.

BACKGROUND Mucinous cystic neoplasm (MCN) of the liver is a rare hepatic neoplasm: a cystic, mucus-producing tumor. Histopathologic examination reveals ovarian-like stroma. The origin of MCN of the liver is still unknown, although ectopic ovarian-like stroma in the liver has been suggested as a possibility. We document a thought-provoking case of MCN of the liver, and intratumoral fatty tissue may support the opinion that ectopic ovarian-like stroma in the liver is a possible origin for both MCN and ovarian teratoma. CASE REPORT An expansive 10.5-cm cystic tumor was incidentally detected in a 71-year-old woman. Imaging studies revealed that the tumor was multiloculated, with cyst contents comprising mucus, muddy-looking fluid (inspissated bile), and hematoma. Imaging studies revealed fatty tissue and calcifications in the cyst walls. The diagnosis of MCN of the liver was made, although MCNs have never been reported to include fatty tissue. Extended left lobectomy was performed, and the tumor was curatively removed without any rupture. A multilocular cyst, mucus, calcifications, and fatty tissue were clearly observed on gross inspection. Histopathological examination revealed ovarian-like stroma. Evidence of malignancy was not detected. Her postoperative course was uneventful. To the best of our knowledge, our patient is the first case of MCN of the liver with intratumoral fatty tissue. This case may support the hypothesis that MCN originates from ectopic ovarian-like stroma in the liver. CONCLUSIONS We documented a thought-provoking case of MCN of the liver in detail, and this MCN accompanied with fatty tissue might originate from ectopic ovarian-like stroma.

INTRODUCTION AND IMPORTANCE: Definitive diagnosis of functioning neuroendocrine neoplasms (NENs) in the pancreas is challenging. Adrenocorticotropic hormone (ACTH) regulates adrenal cortisol production. Ectopic ACTH secretion by functioning NENs may cause hypercortisolism. PRESENTATION OF CASE: A 62-year-old woman who was receiving medications for hypertension and hyperlipidemia was referred to our hospital because of abnormal blood tests. Diabetes mellitus was initially diagnosed. Dynamic computed tomography and endoscopic ultrasound revealed a 35-mm diameter hypovascular tumor in the distal pancreas and multiple liver metastases. Endoscopic ultrasound-guided fine-needle aspiration resulted in a diagnosis of neuroendocrine carcinoma. The patient developed pancreatic leakage progressing to peritonitis, abscess formation, pleural effusion, and ascites after the fine-needle aspiration biopsy. Her clinical condition deteriorated to a septic state, necessitating emergency surgery comprising distal pancreatectomy, intraperitoneal lavage, and drainage. Wound healing was protracted and accompanied by ongoing high white blood cell counts and neutrophilia. She also developed a gastric ulcer postoperatively. Systematic endocrine investigations were performed because hypercortisolism caused by a functioning NEN was suspected. Eventually, a definitive diagnosis of an ACTH-producing NEN in the pancreas was made. Systemic chemotherapy was proposed; however, the patient and her family opted for palliative treatment only. She died 42 days after the initial diagnosis. CLINICAL DISCUSSION: We here present a patient with ACTH-dependent hypercortisolism attributable to a pancreatic NEN who died of progressive cancer after a delay in definitive diagnosis. CONCLUSION: Detailed investigation, including systematic endocrine examination and functional imaging studies, are important for precise diagnosis of, and appropriate treatment for, NENs.
RESUMEN
INTRODUCTION AND IMPORTANCE: Ectopic endometrium in the appendix is rare. The relationships between ectopic endometrium in the alimentary tract and digestive symptoms and between digestive symptoms due to ectopic endometriosis and periodic menstruation are controversial. We herein describe the successful treatment of acute appendicitis that we suspect was caused by ectopic endometriosis and periodic menstruation. PRESENTATION OF CASE: A 38.9-year-old multipara with uterine didelphys developed lower abdominal pain during menstruation, and she was clinically diagnosed with acute appendicitis. She received conservative management with cephem antibiotics, and her pain disappeared uneventfully. However, the lower abdominal pain during menstruation later recurred, and she again received conservative treatment. Laparoscopic appendectomy was subsequently performed because for 4 months, her appendicitis-induced digestive symptoms had recurred in association with periodic menstruation. Ectopic endometrial gland proliferations were histopathologically observed in the proper muscular layer of the appendiceal tip. She developed no further episodes of digestive symptoms postoperatively. CLINICAL DISCUSSION: Ectopic endometriosis of the alimentary tract may be accompanied by digestive symptoms; moreover, these symptoms may be related to periodic menstruation. However, the sensitivity of ectopic endometrium to hormones shows considerable variation among patients. We speculate that the acute appendicitis might have been triggered by ectopic endometriosis in our case because the patient developed repeated digestive symptoms in association with periodic menstruation. Ectopic endometrium may be incidentally observed in histopathological assessments of resected specimens. The therapeutic strategy should be carefully decided on a case-by-case basis. CONCLUSION: We hope this thought-provoking case provides a timely reminder for gastrointestinal clinicians and general surgeons.
RESUMEN
INTRODUCTION AND IMPORTANCE: Splanchnic venous thrombosis (SVT) originating in the superior mesenteric vein (SMV) is rare and may cause acute intestinal infarction (AII). Protein C deficiency (PCD) results in thrombophilia. PRESENTATION OF CASE: Acute unexplained SVT originating in the SMV and portal vein was detected in 68-year-old man. Pan-peritonitis and AII were diagnosed and emergency surgery performed. Part of the small intestine was necrotic and partial resection without anastomotic reconstruction was performed. Heparin was administered intravenously continuously from postoperative day (POD) 1. Hereditary, heterozygous, type 1 PCD was diagnosed postoperatively. The anastomosis was reconstructed on POD 16. Warfarin was substituted for heparin on POD 22. No recurrent thrombosis occurred during 2 years of follow-up. CLINICAL DISCUSSION: Patients with the rare condition of SVT require prompt diagnosis and treatment and may have underlying disease. PCD can cause SVT even in intact veins and anticoagulation therapy should be administered immediately postoperatively. Misdiagnosis and/or delayed treatment of SVT can result in AII, a life-threatening condition with a high mortality rate. Insufficient clinician awareness can result in serious mismanagement of patients with PCD and SVT; emergency patients with AII caused by unexplained SVT should therefore be further investigated for prothrombotic states and assessment of coagulation-fibrinolysis profiles to clarify the underlying mechanism. CONCLUSION: We here present a thought-provoking emergency case of AII associated with acute SVT caused by underlying PCD that was successfully treated by two-stage surgery and anticoagulation therapy. This case provides a timely reminder for emergency clinicians and gastrointestinal surgeons.
RESUMEN
BACKGROUND: Advanced gastric cancer (GC) with liver metastasis is often characterized by multiple and bilobular metastases and may also be associated with extrahepatic metastatic lesions. Hence, many physicians consider that radical surgeries are contraindicated for liver metastases from GC (LMGC). According to the 2017 Japanese treatment guideline for GC, a smaller number of liver metastases without unresectable factors may be an indication for liver resection (LR) with curability. The actual 5-year overall survival (OS) rate ranges from 0 to 0.37. AIM: To present the institutional indications for LR for LMGC and identify important factors for prognostic outcomes. METHODS: In total, 30 patients underwent LR for LMGC during a 14-year period, and we evaluated the clinical, surgical, and oncological findings. In all patients, radical surgery with intentional lymphadenectomy was performed for the primary GC. The median follow-up duration after the initial LR was 33.7 mo, and three patients with no recurrence died of causes unrelated to the LMGC. The OS and recurrence-free survival rates after the initial LR were assessed. RESULTS: Seventeen patients had metachronous LMGC. The initial LR achieved curability in 29 patients. Perioperative chemotherapy was introduced in 23 patients. The median greatest LMGC dimension was 30 mm, and the median number of LMGC was two. Twenty-two patients had unilobular LMGC. The 5-year OS and recurrence-free survival rates were 0.48 and 0.28, respectively. The median survival duration and recurrence-free duration after the initial LR were 16.8 and 8.6 mo, respectively. Twenty-one patients developed recurrence after the initial LR. Additional surgeries for recurrence were performed in nine patients, and these surgeries clearly prolonged the patients' survival. Pathological serosal invasion was an independent predictor of a poor prognostic outcome after the initial LR. Aggressive LR may be indicated for carefully selected patients with LMGC. CONCLUSION: Our results of LR for LMGC seem acceptable. Additional surgeries for recurrence after the initial LR might prolong OS. Pathological serosal invasion is important for poor prognostic outcomes.
RESUMEN
BACKGROUND: Gallbladder cancer (GBC) is the most common biliary malignancy and has the worst prognosis, but aggressive surgeries [e.g., resection of the extrahepatic bile duct (EHBD), major hepatectomy and lymph node (LN) dissection] may improve long-term survival. GBC may be suspected preoperatively, identified intraoperatively, or discovered incidentally on histopathology. AIM: To present our data together with a discussion of the therapeutic strategies for GBC. METHODS: We retrospectively investigated nineteen GBC patients who underwent surgical treatment. RESULTS: Nearly all symptomatic patients had poor outcomes, while suspicious or incidental GBCs at early stages showed excellent outcomes without the need for two-stage surgery. Lymph nodes around the cystic duct were reliable sentinel nodes in suspicious/incidental GBCs. Intentional LN dissection and EHBD resection prevented metastases or recurrence in early-stage GBCs but not in advanced GBCs with metastatic LNs or invasion of the nerve plexus. All patients with positive surgical margins (e.g., the biliary cut surface) showed poor outcomes. Hepatectomies were performed in sixteen patients, nearly all of which were minor hepatectomies. Metastases were observed in the left-sided liver but not in the caudate lobe. We may need to reconsider the indications for major hepatectomy, minimizing its use except when it is required to accomplish negative bile duct margins. Only a few patients received neoadjuvant or adjuvant chemoradiation. There were significant differences in overall and disease-free survival between patients with stages ≤ IIB and ≥ IIIA disease. The median overall survival and disease-free survival were 1.66 and 0.79 years, respectively. CONCLUSION: Outcomes for GBC patients remain unacceptable, and improved therapeutic strategies, including neoadjuvant chemotherapy, optimal surgery and adjuvant chemotherapy, should be considered for patients with advanced GBCs.
RESUMEN
BACKGROUND Pancreatic metastasis from colorectal cancer is rare and can masquerade as primary pancreatic cancer. CASE REPORT A 70-year-old male was diagnosed with advanced rectal cancer with multiple liver metastases. After neoadjuvant chemotherapy, he underwent radical surgery for the primary tumor and hepatectomy for multiple liver metastases. Adjuvant chemotherapies and additional surgeries were subsequently required for recurrences in the liver, lung, and lymph nodes. A diffuse hypovascular nodule in the pancreatic head and a solitary liver metastasis were detected 2.5 years after the initial surgery and he accordingly underwent further chemotherapy. However, the pancreatic tumor progressed, invading the pancreatic duct and biliary tract. Obstructive jaundice finally prompted discontinuation of chemotherapy and he underwent biliary drainage. His diffuse and hypovascular tumor was clinically and radiographically diagnosed as a primary pancreatic cancer. Pancreatic resection for the pancreatic tumor and hepatectomy for the liver metastasis were performed 4.2 years after the initial surgery, achieving radiographic and surgical curative resection. Pathological examination of the surgical specimen resulted in a definitive diagnosis of metachronous pancreatic metastasis from his primary rectal cancer. Despite further chemotherapy, his general condition worsened; however, he remains alive 5.4 years after the initial surgery, with best supportive care. CONCLUSIONS Pancreatic metastasis originating from rectal cancer can masquerade as primary pancreatic cancer clinically and radiologically. Multimodality treatment is mandatory for metastatic colorectal cancer. Aggressive surgeries for pancreatic metastasis should be considered if curative resection appears possible radiographically and/or intraoperatively.

BACKGROUND: Postoperative pancreatic leakage readily results in intractable pancreatic fistula and subsequent intraperitoneal abscess. This refractory complication can be fatal; therefore, intensive treatment is important. Continuous local lavage (CLL) has recently been reevaluated as effective treatment for severe infected pancreatitis, and we report three patients with postoperative intractable pancreatic fistula successfully treated by CLL. We also discuss our institutional protocol for CLL for postoperative pancreatic fistula. CASE SUMMARY: The first patient underwent subtotal stomach-preserving pancreaticoduodenectomy, and pancreatic leakage was observed postoperatively. Intractable pancreatic fistula led to intraperitoneal abscess, and CLL near the pancreaticojejunostomy site was instituted from postoperative day (POD) 8. The abscess resolved after 7 d of CLL. The second patient underwent distal pancreatectomy. Pancreatic leakage was observed, and intractable pancreatic fistula led to intraperitoneal abscess near the pancreatic stump. CLL was instituted from POD 9, and the abscess resolved after 4 d of CLL. The third patient underwent aneurysmectomy and splenectomy with wide exposure of the pancreatic parenchyma. Endoscopic retrograde pancreatic drainage was performed on POD 15 to treat pancreatic fistula; however, intraperitoneal abscess was detected on POD 59. We performed CLL endoscopically via the transgastric route because the percutaneous approach was difficult. CLL was instituted from POD 63, and the abscess resolved after 1 wk of CLL. CONCLUSION: CLL has therapeutic potential for postoperative pancreatic fistula.
RESUMEN
BACKGROUND Anastomotic failure after gastroenterological surgery is usually treated by intraperitoneal drainage and a mature ductal fistula. A ductal fistula may develop into a labial fistula. Although a ductal fistula is controllable, a labial fistula is intractable. We report a case of a labial fistula that communicated with the duodenal stump after gastrectomy. This condition was successfully treated by intraluminal drainage with continuous suction (IDCS) via a rectus abdominis musculocutaneous flap (RAMF). CASE REPORT A 70-year-old male underwent distal gastrectomy with intentional lymphadenectomy because of advanced gastric cancer. Digestive reconstruction was completed by the Billroth II method. Pancreatic leakage, intraperitoneal abscess, and anastomotic failure of gastrojejunostomy occurred after surgery. The duodenal stump was ruptured at postoperative day (POD) 26, and ductal fistula associated with the duodenum was observed. Unfortunately, this ductal fistula developed into a labial fistula at POD 90, and a high output of duodenal juice was observed. Additional surgery was proposed at POD 161. The broken stump and labial fistula were covered by a pedunculated RAMF, and a dual drainage system (a combination of a Penrose drain and a 2-way tube) travelled through the RAMF. The tip position of the drainage system was located in the duodenum, and the IDCS was effectively introduced. The secondary ductal fistula finally matured through the RAMF, and was subsequently closed at POD 231. The intractable labial fistula was successfully treated, and the patient was discharged at POD 235. CONCLUSIONS A high-output labial fistula, which communicated with the duodenal stump after gastrectomy, was refractory in our patient. Effective IDCS through an RAMF was useful for replacement of the labial fistula with a secondary ductal fistula.

BACKGROUND Aneurysm of the inferior pancreaticoduodenal artery (IPDA) is rare among visceral artery aneurysms. Aneurysm and/or pancreatitis may have a causal relation with hemosuccus pancreaticus (HP). HP causes an obscure bleeding in the digestive tract, and this rare disease may lead to life-threatening condition. Although interventional radiology is generally employed as the initial treatment for visceral aneurysms, aneurysmic recanalization is a critical problem. CASE REPORT A 58-year-old male was incidentally diagnosed as groove pancreatitis, and his pancreatitis was successfully treated by conservative management. One year later, an IPDA aneurysm was detected in image studies. Gastrointestinal bleeding was objectively observed, and a diagnosis of asymptomatic HP was made. Arterio-pancreatic duct fistula was suspected, but was not identified. Coil embolization was successfully completed. Six months later, he suffered a relapse of HP, and visited our emergency unit. Pseudocystic lesion around metallic coils were confirmed. Subtotal stomach-preserving pancreaticoduodenectomy without any extended resections was performed. Intentional dissections of nerve plexuses and lymph nodes were all waived. Even a pancreatography of the resected specimen did not clarify his arterio-pancreatic duct fistula. He was discharged at postoperative day 10, and smoothly returned to his work. CONCLUSIONS Pancreatic juice-related complications after advanced pancreaticoduodenectomy for malignancies are often intractable. However, simple pancreaticoduodenectomy which omits extended resections and intentional dissections is safe and feasible for benign diseases. After the initial interventional radiology for pancreatic aneurysms, an elective pancreatic surgery should be considered to avoid unwanted recanalization and refractory HP.

BACKGROUND Visceral arterial aneurysms are rare. Most splenic arterial aneurysms (SAAs) are saccular and are in the distal third of the splenic artery. Suggested major causes of SAAs are atherosclerosis, pregnancy, and inflammation. We report the case of a patient who with a SAA extending almost the full length of his splenic artery. CASE REPORT A solitary true aneurysm that extended almost the entire length of the splenic artery was incidentally detected in an asymptomatic 70-year-old male patient with a history of myasthenia gravis and diabetes mellitus. His SAA was severely calcified, but other arteries showed no calcification. The aneurysm had been slightly enlarged toward the celiac artery for 2 years, and aneurysmectomy and splenectomy were performed. Vascular clips were carefully placed at the intact splenic artery without disturbing arterial flows from the celiac artery. Arterial branch from the SAA was ligated at an intact area, and the pancreatic capsule was densely adherent with the calcified aneurysm wall. The pancreas was preserved, although the pancreatic parenchyma was widely exposed during aneurysmectomy. Pathological examination revealed no atherosclerotic changes. Postoperatively, a pancreatic fistula developed, which was treated by placing an intraperitoneal drain and retrograde pancreatic drainage tube. Nevertheless, the intractable pancreatic fistula triggered a bacteriogenic infection, resulting in intraperitoneal abscess. Continuous local lavage via transnasal continuous infusion and endoscopic transgastric drainage was performed, until the fistula closed. He was healthy at 9 months after surgery. CONCLUSIONS A SAA that had the rare form and solitary origin was treated. Continuous local lavage has a therapeutic potential for a pancreatic juice-related bacteriogenic complication.

PURPOSE: Cancerous involvement of a ureter is sometimes encountered in pelvic surgery for malignancy. We usually perform transureteroureterostomy (TUU) in cases of unilateral lower ureteral cancerous involvement. We report the outcomes in patients treated with TUU in our institute. METHODS: We retrospectively reviewed the medical records of 11 patients who underwent TUU between June 2006 and September 2015. RESULTS: The primary disease was colon cancer in five patients, rectal cancer in four, and uterine cervical cancer and ovarian cancer in one patient each. Early postoperative complications relevant to TUU occurred in four patients; however, three patients were managed conservatively and recovered quickly. Only one patient developed ureteral obstruction, which resulted from anastomotic hematoma. Follow-up periods ranged from 5 to 78 months with a median of 28 months. The median estimated glomerular filtration rate before and after TUU was 59 ml/min (range, 31-90 ml/min) and 62.0 ml/min (range, 43-127 mL/min), respectively. No patients experienced worsening of their renal function or recurrent urinary tract infection. CONCLUSIONS: Short-term outcomes are good and long-term renal function is maintained following TUU. TUU is considered a feasible technique for ureteral reconstruction for pelvic malignancy, and TUU has great potential in the era of multimodal therapy.

A solitary fibrous tumor is a ubiquitous mesenchymal fibroblastic tumor that was previously considered limited to the pleural cavity. Here, we report a rare case of a large solitary fibrous tumor of the mesorectum, which was successfully resected laparoscopically. A 56-year-old woman was referred to our hospital for a giant pelvic mass. Pelvic MRI showed a well-circumscribed mass, 12 cm in diameter, with heterogeneous signal intensity on T2 -weighted images. It was diagnosed as a benign mesorectal tumor of unknown origin. We successfully resected the entire tumor laparoscopically. Histological examination revealed it to be an extrapleural solitary fibrous tumor. For large tumors in the pelvis, the laparoscopic approach is preferable in terms of intraoperative hemorrhage, as long as they do not invade surrounding tissues.
