Gastric lipoma is a typical benign submucosal tumor that is usually asymptomatic and is generally detected incidentally when performing gastroscopy. However, depending on its size and location, an atypical gastrointestinal lipoma can cause abdominal pain, diarrhea, constipation, intestinal obstruction, intussuception and life-threatening gastrointestinal bleeding. We report herein a case of gastric lipoma with bleeding in a 43-year-old man. The gastroscopy showed a 4×4 cm ulcero-fungating submucosal mass at the anterior wall of the gastric antrum. Laparoscopic gastric wedge resection was performed and the lesion was diagnosed as gastric lipoma.

목적: 직장 신경내분비종양의 치료에서 밴드결찰술을 이용한 점막하절제술은 점막절제술에 비하여 시술시간이 짧고 합병증의 발생이 적은 것으로 보고된다. 본 연구에서는 밴드결찰술을 이용한 점막하절제술이 기존의 점막절제술보다 더 우수한지 알아보고자 하였다. 대상 및 방법: 2007년 3월부터 2017년 5월까지 직장 신경내분비종양으로 밴드결찰술을 이용한 점막하절제술과 점막절제술로 치료한 환자를 대상으로 분석하였다. 결과: 총 148명의 환자가 등록되었으며, 120명은 밴드결찰술을 이용한 점막하절제술로 치료하였고, 28명은 점막절제술로 치료하였다. 밴드결찰술을 이용한 점막하절제술이 완전 절제율과 치유 절제율에서 점막절제술보다 우수한 성적을 보고하였다(93.3% vs. 75.0% and 92.5% vs. 71.4%, p=0.009 and p=0.003, respectively). 결론: 직장 신경내분비종양의 치료에서 밴드결찰술을 이용한 점막하절제술은 점막절제술보다 더 우수한 치료 술기이다. Background/Aims: Ligation-assisted endoscopic submucosal resection (ESMR-L) is preferred for the treatment of rectal neuroendocrine tumors because its results are better than those for endoscopic mucosal resection (EMR), and the procedure time is shorter and the incidence of complications is lower than endoscopic submucosal dissection. The aim of this study was to evaluate the clinical usefulness of ESMR-L compared with EMR for rectal neuroendocrine tumors. Methods: From March 2007 to May 2017, 148 patients diagnosed with rectal neuroendocrine tumors were divided into ESMR-L and EMR groups and analyzed retrospectively. Results: Of 148 patients with rectal neuroendocrine tumor, 120 had ESMR-L and 28 had EMR. The ESMR-L group had a significantly higher rate of complete resection and curative resection than the EMR group (93.3% vs. 75.0% and 92.5% vs. 71.4%, p=0.009 and p=0.003, respectively). Conclusions: ESMR-L for the treatment of small rectal neuroendocrine is a significantly superior modality to EMR. (Korean J Gastroenterol 2018;72:128-134)

Acinic cell carcinoma (ACC) is an uncommon malignant tumor of the salivary glands that is difficult to diagnose. It grows slowly and shows distant metastasis rarely. We experienced a case of recurrent ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy. The 29-year-old man had been suffering from severe multiple bones and joints pain for 2 months. Ten years earlier, he underwent superficial parotidectomy due to a right subauricular mass. The mass was diagnosed with ACC. After surgery, the tumor recurred twice. Then the patient was diagnosed with cardiac metastasis via positron emission tomography-computed tomography and trans-thoracic echocardiography. He also had hypertrophic osteoarthropathy with multiple bone metastasis. He was given palliative radiotherapy and conservative treatment. ACC in the parotid gland with cardiac metastasis and hypertrophic osteoarthropathy has not yet been reported in literature. From this case, it is recommended to evaluate multiple distant metastasis in the ACC of the parotid gland when joint and bone pain are present.

Patients treated with peritoneal dialysis have increased intra-abdominal pressure and a high prevalence of abdominal wall complications. Hernias can lead to significant morbidity in patients on peritoneal dialysis. Hernias are clinically important because of the risk of incarceration, strangulation and subsequent bowel obstruction, rupture, and peritonitis. In this paper, a case of incarcerated umbilical hernia with small bowel obstruction in a continuous ambulatory peritoneal dialysis (CAPD) patient is reported. The small bowel obstruction improved after herniorrhaphy, and the peritoneal dialysis was resumed 2 weeks after the herniorrhaphy. The patient had been undergoing CAPD without technical failure until the 2 months follow-up after the herniorrhaphy. This case shows that early detection of incarcerated umbilical hernia and herniorrhaphy can prevent resection of a strangulated small bowel so that it can remain on CAPD without post-operative technical failure. Umbilical hernias should be carefully observed and intestinal obstruction should be considered when a CAPD patient with an umbilical hernia has abdominal pain.

Primary retroperitoneal mucinous cystadenoma is an extremely uncommon tumor, even though mucinous cystadenoma often develops in the ovary and less frequently in the pancreas. A 21-year-old female was admitted to our hospital due to severe abdominal pain. A well-demarcated, oval shaped cystic tumor at the retropancreatic area with displacement of the pancreas and surrounding major vessels was observed on CT and MRI. Exploratory laparotomy was performed, and complete excision of the entire cyst was performed without complication. The pathologic finding was consistent with primary retropancreatic mucinous cystadenoma. To the best of our knowledge, this report is the first to describe a case of retropancreatic mucinous cystadenoma arising from the retropancreatic area in Korea.
