An Amyand’s hernia is characterised as the presence of the appendix in an inguinal hernial sac. During laparoscopic cholecystectomy for gallbladder polyps, an incidental Amyand’s hernia was discovered in a 75-year-old female patient. On examination, the hernia contained an appendiceal mucocele but no evidence of perforation. An open appendicectomy with tension-free mesh repair was performed for the hernia. The histopathological report of the appendix was a low-grade appendiceal mucinous neoplasm (LAMN), an entity that is just as rare as an Amyand’s hernia. The patient had the right inguinal swelling for over 10 years but it was thought to be an inguinal intramuscular cyst as reported on a previous abdominal ultrasound. Mucocele of the appendix may have a benign or malignant appendiceal progress, leading to individualised diagnosis and treatment. We review an Amyand’s hernia with LAMN and discuss the asymptomatic tendency yet malignant potential of appendiceal mucoceles along with treatment strategies.

Abstract PDF: An appendicovesical fistula is defined as an abnormal communication between the appendix and the urinary bladder, with only a few cases reported in the literature. It is very challenging to make an early diagnosis, due to the inability of conventional imaging modalities to detect this unique pathology. The symptoms are often mild, and there are not any specific signs or symptoms that might suggest this type of anomalous communication. We report a case of a 27-year-old male patient who presented difficulty for initiating urination, dysuria, and persistent urinary tract infections. An abdominal x-ray showed a large calculus inside the bladder. A cystoscopy was performed, where the tip of the appendix was seen protruding inside the bladder with a large fecalith adhered to the bladder wall. An appendectomy and partial cystectomy with primary repair were auspiciously achieved. A review of the literature is also presented.

Abstract PDF

Torsion of the appendix is rare, and appendiceal mucocele can be one of its causes. The first case was of a 49-year-old man who visited the emergency room (ER) for abdominal pain. Abdominal computed tomography (CT) showed appendiceal mucocele with suspected torsion and rupture. The patient underwent laparoscopic exploration and appendectomy. The second case was of a 69-year-old man who visited the ER for epigastric pain. Abdominal CT showed suspicious appendiceal mucocele with ischemic change, indicating torsion of the appendix. The twisted appendix was successfully removed by laparoscopic exploration. An appendiceal mucocele is one of the causes of twisted appendix. With torsion, the mucocele can be diagnosed as rupture by ischemia which may lead to pseudomyxoma peritonei. For this reason, open laparotomy has traditionally been preferred. However, an unruptured appendiceal mucocele or impending rupture with torsion of the appendiceal mucocele can be treated with totally laparoscopic surgery.

Abstract PDF

Common causes of lower gastrointestinal bleeding include diverticular disease, vascular disease, inflammatory bowel disease, neoplasms, and hemorrhoids. Lower gastrointestinal bleeding of appendiceal origin is extremely rare. We report a case of lower gastrointestinal bleeding due to angiodysplasia of the appendix. A 72-year-old man presented with hematochezia. Colonoscopy showed active bleeding from the orifice of the appendix. We performed a laparoscopic appendectomy. Microscopically, dilated veins were found at the submucosal layer of the appendix. The patient was discharged uneventfully. Although lower gastrointestinal bleeding of appendiceal origin is very rare, clinicians should consider it during differential diagnosis.

Abstract PDF

We report a case of a goblet-cell carcinoid tumor of the appendix which metastasized to the peritoneum and was treated by using cytoreductive surgery (CRS) with intraperitoneal chemotherapy. A 47-year-old male presented with chronic constipation and was diagnosed as having a rectal adenocarcinoma with a signet-ring-cell component under colonoscopy. Computed tomography suggested peritoneal metastases with diffuse nodular parietal peritoneal thickening of the entire abdomen and focal invasion of the upper rectum by a seeding mass. CRS with intraperitoneal chemotherapy was done under the diagnosis of a rectal adenocarcinoma with peritoneal metastases. The pathologic diagnosis was a goblet-cell carcinoid tumor of the appendix with peritoneal metastasis. The histological discrepancy between a peritoneal metastatic mass and a rectal mass was due to the mixed histological pattern of a goblet-cell carcinoid tumor. A metastatic mass may not share identical immunohistochemical characteristics from its origin. This histologic discrepancy necessitates caution in diagnosing a distant metastasis of a goblet-cell carcinoid tumor.

Abstract PDF

Lower gastrointestinal bleeding is a common disease among elderly patients. The common sources of lower gastrointestinal bleeding include vascular disease, Crohn's disease, neoplasm, inflammatory bowel disease, hemorrhoid, and ischemic colitis. However, bleeding from the appendix has been reported very rarely in patients with lower gastrointestinal tract bleeding. In general, after a colonoscopic diagnosis of appendiceal bleeding, a laparoscopic or surgical appendectomy would be recommended. We report a case of successful colonoscopic treatment of appendiceal bleeding without complications by endoclips. This report suggests that colonoscopic clipping is a safe and effective means to treat bleeding from appendiceal lesions. Further study is needed to evaluate procedure-related complications and to confirm the procedure's safety and efficacy.

Abstract PDF

Appendicular schwannoma is a rare tumor originating from Schwann's cells in the Auerbach plexus. The preoperative diagnosis is difficult because the clinical features are nonspecific, and it is mostly found accidentally via a radiologic image as a tumor, mimicking malignancy. We report a case of an appendicular schwannoma coexisting with an adenocarcinoma in the lung. A laparoscopic appendectomy was done with a clear resection margin, and the immunohistochemical staining showed positive S-100 protein, which confirmed the schwannoma. The patient also underwent a left upper lobectomy of the lung. The patient has been free of recurrence for the 6 months since the operation. The laparoscopic approach could be available for treatment of an appendicular schwannoma, thus avoiding an unnecessary laparotomy.

Abstract PDF: A goblet cell appendiceal carcinoid (GCAC) is an uncommon tumor. It shares the histologic features of both adenocarcinoma and conventional carcinoids. The metastatic potential of GCAC is higher than that of classic appendiceal carcinoids. Their management, whether an appendectomy alone is an adequate treatment or whether a right hemicolectomy is indicated, is still under debate. The metastatic potential of GCAC is similar to that of classic appendiceal carcinoids and depends on the tumor size and the mitosis rate. Therefore, some authors advocate a simple appendectomy, not expanding beyond the appendix adventitia, for selected patients with tumors less than 1 cm in diameter with a low mitosis rate (<2/10 HPF). Otherwise, a right hemicolectomy is indicated for all other patients to reduce the risk of developing metastatic disease. Chemotherapy is the usual treatment option for metastatic disease, but more data are required if an optimal regimen is to be determined. Finally, colonoscopy plays an important role in patients with an appendiceal adenocarcinoid because of their high risk of developing a colorectal adenocarcinoma. Recently, we discovered one case of a GCAC that was diagnosed incidentally at appendectomy. A 48-yr-old man visited the emergency department with the symptom of right lower quadrant abdominal pain. Acute appendicitis was suspected after evaluation, and a laparoscopic appendectomy was performed. The type of appendicitis was gangrenous, and there were no obvious signs of malignancy. However, a pathologic diagnosis of a goblet cell carcinoid was made. A laparoscopic right hemicolectomy was subsequently performed. The patient received 5 cycles of chemotherapy applied to the goblet cell carcinoid and has shown no other remarkable indispositions during the last 12 mo.

Abstract PDF: Appendiceal bleeding is a kind of lower gastrointestinal bleeding. For treatment, it is essential to identify the location of the lower gastrointestinal tract bleeding. Appendiceal bleeding has some diagnostic difficultie. It is a very rare condition, and colonoscopy shows only the appendiceal orfice. Recently, multidetector computed tomography has increasingly been used in the diagnostic evaluation of most vascular diseases. Herein, we report the case of an appendiceal bleeding diagnosed by using abdominal multidetector computed tomography, and we present a the literature.

Abstract PDF: Crohn's disease is a chronic condition characterized by a non-specific granulomatous necrosis involving potentially any location in the alimentary tract, but a primary lesion confined to the appendix alone is very rare. It is difficult to discriminate Crohn's appendicitis from acute appendicitis preoperatively because of their clinical similarities. Because Crohn's disease confined to the appendix has a more favorable prognosis than typical Crohn's disease, it is considered a separate disease from Crohn's disease. Recently, the term idiopathic granulomatous appendicitis has gained wide acceptance as a distinct disease entity. We experienced a case of Crohn's disease giving rise to appendicitis or idiopathic granulomatous appendicitis and report a case with a review of the literature.

Abstract PDF: A primary malignant fibrous histiocytoma (MFH) is a soft tissue sarcoma of mesenchymal origin. A primary MFH occurs most commonly in the extremities and the trunk in adults, but rarely in the alimentary tract. We report a case of MFH of the mesoappendix in a 49-year-old male who presented with a periappendiceal abscess. To the best of our knowledge, this is the first report of MFH in the large intestinal tract, including the appendix, in Korea. The patient recovered well after a right hemicolectomy and was given adjuvant chemotherapy.

Abstract PDF: The incidence of an appendiceal diverticulum in instance of appendectomies has been reported to range from 0.004 to 2.1 percent. It is known that diverticulum of the appendix leads to diverticulitis, appendicitis, or perforation. Recently in the literature, appendiceal diverticulum without inflammation has been reported as a possible cause of chronic abdominal pain. We report the case of a 40-year-old man with appendiceal diverticula associated with chronic abdominal pain.

Abstract PDF: An adenocarcinoma of the appendix is a rare tumor, and so far only 130 cases have been reported worldwide. We report one patient with peritoneal seeding of an adenocarcinoma. A 51-year-old man was admitted to our hospital with the impression of intestinal obstruction. He had undergone an appendectomy 5 years ago due to acute appendicitis. At that time, postoperative histopathological analysis had revealed an adenocarcinoid tumor in the appendix. The patient had been told to visit our hospital for follow-up but he hadn't visited. When he finally visited our hospital diagnostic laparoscopy revealed the peritoneal seeding of a recurrent adenocarcinoma. A palliative right hemicolectomy was done to relieve the bowel obstruction. After recovering from operation, the patient was treated with the 5-fluoruracil, leucovorin, and oxaloplatin (FOLFOX). The patient was discharged in improved general condition with a future plan for regular cyclic chemotherapy.

Abstract PDF: Crohn's disease is a chronic and insidious condition characterized by an inflammatory process that may extend across all layers of the entire gastrointestinal tract. The common sites involved by Crohn's disease are the terminal ileum and ascending colon. Crohn's disease limited to the appendix is uncommon. Since its first report in 1953 by Meyerding and Bertram, 156 cases of appendiceal Crohn's disease have been documented in the world literature. We experienced a case of Crohn's disease limited to the appendix in a-35year-old female who were performed an ileocecectomy.
