JOURNAL FREE ACCESSIntraductal papillary mucinous tumor (IPMT) of the pancreas grows slowly and is consid-ered good prognosis, however sometimes progress rapidly with a poor prognosis. Although various imaging modalities have been advocated to differentiate between benign IPMTs and malignant ones, it is not easy to obtain definite diagnosis based on these parameters. Endos-copic examinations of IPMTs include ERCP, cytological examination by using pancreatic juice, endoscopic ultrasonography (EUS), intraductal ultrasonography (IDUS), and peroral pancreatoscopy (POPS). Characteristic findings of duodenal papilla on ERCP facilitate making diagnosis of IPMT, however differentiation of benign IPMTs from malignant ones is often difficult only by ERCP. Cytological examination is sometimes complicated but deserved as an definite diagnosis. EUS is comparably less invasive, and utilized in screening. IDUS can estimate pancreatic duct wall and parenchyma as well as intra-luminal space of the duct. POPS enables to assess protruding lesions of IPMT much precisely. Treatment strategy for IPMTs will be reliably done by these endoscopic examinations.View full abstractDownload PDF (18003K) -

JOURNAL FREE ACCESSA 82-year-old-woman was hospitalized because of the hemorrhagic small intestinal an-giodysplasia with general malaise. On emergent gastrointestinal fiberscopy, we formed a duodenal vascular ectasia with two bleeding spots among several vascular ectasia at the superior duodenal angle. We successfully treated the two hemorrhagic vascular ectasia using a ligating device for endoscopic variceal ligation (EVL). Permanent hemostasis was obtained with one procedure with out side effects. EVL appeared to be useful for small hemorrhagic lesions of small intestine.View full abstractDownload PDF (15455K) -

JOURNAL FREE ACCESSA 77 year old woman was admitted to our hospital with anal bleeding. Colonoscopy revealed the polypoid mucosa in the sigmoid colon. Contrast medium enema revealed the flapping stripped mucosa easily pushed back to the descending colon by air pressure with diffuse circular ulceration of lower descending colon. The patient had taken warfarin potassium' for the anticoagulation therapy until the onset. The medication of warfarin was stopped and the conservative treatment with total parenteral nutrition was performed. Because healing tendency was confirmed by colonoscopy, anticoagulation therapy was started again. However the medication caused recurrent anal bleeding ten days later. So anticoagulation therapy with warfarin potassium was substituted for the antiplatelet therapy with aspirin. After 3 months, the ulcer was healed over with little stenosis. The passage of a stripped colonic mucosa have been rarely reported. In our case, this ulceration seemed to be caused not by ischemic colitis but by mucosal dissection due to submucosal hematoma, because colonoscopy revealed discreat regular margined ulcer without inflammation on the anal side of the ulcer lesion. Therefore, the passage of a colonic mucosa might have occurred from submucosal hematoma due to bleeding tendency by warfarin potas-sium.View full abstractDownload PDF (10487K) -

JOURNAL FREE ACCESSThe patient was a 67-year-old woman. An elevated lesion like submucosal tumour was found in the cecum on colonoscopic examination. The tumour moved peristaltically and vanished into the appendiceal orifice. It was diagnosed as intussusception of the appendix. As we could not deny a malignant disease as a cause of the intussusception, laparoscopic appendec-tomy was performed. On pathological examination, no tumourous lesion was found. The fecal cluster in the appendix was considered to be the cause of appendiceal intussusception.View full abstractDownload PDF (8597K) -

JOURNAL FREE ACCESSA 73-year-old man received radiation therapy (external radiation with 70 Gy) for car-cinoma of the prostate. Bleeding at the rectum occurred approximately eight months after irradiation. Severe bleeding and anemia could not be controlled by hyperbaric oxygen therapy, argon plasma coagulation and sucralf ate enemas. Therefore, we treated this patient with ecabet sodium enema, which is reported to be effective on ulcerative colitis. Bleeding and anemia gradually improved with this treatment. It is suggested that ecabet sodium enema can be an available treatment for radiation colitis.View full abstractDownload PDF (8438K) -

JOURNAL FREE ACCESSA 45-year-old man, who went into shock after he was cut external jugular vein with handicraft cutter, was brought into the hospital by ambulance. We ligated external jugular vein, and he survived. He complained left lower abdominal pain and bloody diarrhea for 4 days, right after our treatment. Colonoscopy revealed constriction with mucosal edema and multiple ulcers from sigmoid colon to descending colon. We diagnosed as shock-associated ischemic colitis after hemorrhagic shock. Only one similar case have been reported on the international literature.View full abstractDownload PDF (7939K) -

JOURNAL FREE ACCESSAn 86-year-old man was admitted to the hospital because of an obstructed descending colon cancer, and his general condition was poor because of multiple liver metastases and bedridden. Since he also had a past history of rectal cancer and surgical operation was very difficult. Then an expandable metallic stent (EMS) was placed into the stenosis and the result was good. In cases of colorectal malignant stenosis without radical curability, it is common to perform the operation, such as colostomy. Although a good result with EMS placement has been reported in recent years, the application would be difficult in a general hospital from the aspect of cost.View full abstractDownload PDF (11092K) -

JOURNAL FREE ACCESS[Purpose] The aim of this study was to evaluate the observation and treatment by transgastrostomic endoscopy (TGE) using a small-caliber endoscope. [Methods] TGE was performed with a small-caliber endoscope GIF-XP240 (Olympus, Tokyo) to observe upper gastrointestinal tract. Endoscopic mucosal resecrion (EMR) against early gastric cancer was performed with GIF-Q240 (Olympus, Tokyo) supported by TGE using the technique of endos-copic submucosal dissection. J-TubeTM (Boston Scientific, Natick, MA) was also inserted up to upper jejunum through PEG using TGE. [Results] TGE was inserted up to upper jejunum in 47 out of 51 cases. 14 novel lesions following PEG were observed in 46 cases, including reflux esophagitis in 5 cases. We were able to perform easily and safely endoscopic submucosal dissection in 2 cases of early gastric cancer, and insertion of jejunal tube through gastrostomy in 4 cases of aspiration pneumonia. [Conclusion] TGE was useful for the observation and treatment after PEG.View full abstractDownload PDF (14055K) -

JOURNAL FREE ACCESSIn endoscopic injection sclerotherapy for esophageal varices, it is considered that emboliza-tion of both esophageal varices and their feeders are essential to lower the recurrence rate after sclerotherapy. For this, I highly recommend balloon occluded retrograde injection sclerother-apy (B-RIS), a technique which injects a sclerosant with addition of a contrast medium into esophageal varices under X-ray fluoroscopy and stops the injection just as the agent is filled up feeders.View full abstractDownload PDF (14074K) -

JOURNAL FREE ACCESSWe herein report a case of ampullary cancer in 65-year-old man who underwent endoscopic papillectomy. Duodenoscopy revealed an exposed-type tumor mass at the ampulla of Vater. Histology of the biopsy specimen demonstrated well-differentiated adenocarcinoma. Endos-copic ultrasonography and intraductal ultrasonography showed a hypoechoic mass limited to the ampulla of Vater (clinical stage, T1). Endoscopic papillectomy was performed after informed consent was obtained. Histological examination of the resected specimen revealed adenocarcinoma limited to the ampulla of Vater (final stage, pT1). Both accurate preoperative T staging and proper histological evaluation of the resected specimen appear to justify endos-copic treatment of early ampullary cancer.View full abstractDownload PDF (13102K) -

JOURNAL FREE ACCESSBackground : Microwave or radiofrequency ablation therapy has been widely perfomed for hepatocellular carcinoma (HCC). Whereas ablation therapy is effective treatment, it cannot be perfomed easily, as is evident in several reports of severe complications. We treated surface-type HCC under laparoscopy in avoidance of complications from March 1996. In the present study, we examined the efficacy and long term outcome of laparoscopic ablation therapy. Patients and Methods : The patients were 47 cases (58 lesions) of HCC treated by laparos-copic ablation therapy under general anesthesia in our Center from March 1996 until March 2003. Results : The surface-type HCC to which the therapy was applicable accounted for approx-imately 15% of all cases. The overall 5-year survival rate was 62%. Hepatic reserve and rate of intrahepatic recurrences in the remnant liver after curative treatment were the limiting factors on the survival rate. There was no serious complication in the treatment. It was well tolerated and brought about good quality of life. Conclusion : Laparoscopic ablation therapy was considered to be an easy and effective approach, and its utility was also recognized in the avoidance of the problems of percutaneous treatment, such as bleeding or damage to the adjacent organs.View full abstractDownload PDF (8811K) -
