A Case of Successful Laparoscopic Management on Appendiceal Bleeding Diagnosed by Colonoscopy / 대한소화기내시경학회지

Appendiceal causes of lower gastrointestinal bleeding are rare, and identification of the bleeding site is critical. Identification of the bleeding site can be difficult. The differential diagnosis of bleeding in the appendix includes diverticulum, appendicitis, angiodysplasia, Crohn's disease, and appendiceal intussusception, which leads to mucosal erosion and vascular exposure by underlying inflammation. Laparoscopic surgery is commonly performed as a therapeutic procedure for the appendix, also can be a valuable tool in the diagnosis and treatment of hemorrhaging from the appendix. Appendiceal bleeding is rare, and laparoscopic management cases are not widely reported. Herein, we report a case of successful laparoscopic management of appendiceal bleeding diagnosed by colonoscopy with a review of the literature.

Clinical Characteristics of Patients with Chronic Constipation after Radical Hysterectomy or Delivery / 대한소화기학회지

BACKGROUND/AIMS: This study was aimed to analyze the clinical characteristics of patients who developed constipation after radical hysterectomy or delivery and to investigate the results of biofeedback therapy for these patients. METHODS: Thirty-five chronic constipation patients with radical hysterectomy (radical hysterectomy group), 27 chronic constipation patients with delivery (delivery group) and 27 constipation patients with no history of hysterectomy or delivery (control group) were included. Clinical characteristics of these patients, including the results of biofeedback therapy, were analyzed. RESULTS: The delivery group showed higher rates of pelvic floor dyssynergia than the control group (14/27, 52% vs. 6/27, 22%; p<0.05). The prevalence of slow transit constipation was lower in the radical hysterectomy group and delivery group than in the control group (7/35, 20% and 5/27, 19% vs. 12/27, 44%; p<0.05). The prevalence of anatomical abnormalities was not different between the groups. The radical hysterectomy group showed higher rate of obstructive sensation and the delivery group showed higher rate of hard stool and digital maneuvers. The biofeedback therapy was effective in 10 out of 12 patients (91%) among the radical hysterectomy and delivery group. CONCLUSIONS: Radical hysterectomy and delivery seem to induce functional constipation, which may be caused by anorectal dysfunction such as pelvic floor dyssynergia. The biofeedback treatment was effective in functional constipation after radical hysterectomy or delivery.

A Case of Metastatic Non-small Cell Lung Cancer Presenting with Numb Chin Syndrome / 결핵

Numb chin syndrome is a rare clinical manifestation, characterized by focal sensory loss and paresthesia of the chin. It is more often associated with cancer than with benign disorders, and can be the first manifestation of a cancer. A 60-year-old man presented with focal numbness of right chin and gingiva for 10 days. Chest computed tomography showed a 3 cm sized mass on the distal left main-stem bronchus. Squamous cell carcinoma was diagnosed on bronchoscopic biopsy. However, bony metastasis of mandible was not evident on reontgenogram, CT scan, bone scintigram and positron emission tomography. Despite the chemotherapy with three cycles of paclitaxel and cisplatinum, the cancer was progressed and pain on the right chin was developed 4 months .later. Bone scintigram showed multiple bony metastasis including mandible. Here we report this case with a brief review of the appropriate literature.

A Case Report of Atypical Rectal Carcinoid / 대한소화기내시경학회지

Carcinoid tumors arise from enterochromaffin cells of neural crest origin. Rectal carcinoid tumors make up 1 to 2% of all rectal tumors. Approximately 50% of rectal carcinoid tumors are found incidentally on routine endoscopy, and they are asymtomatic. Rectal carcinoid is easily diagnosed by the characteristic submucosal tumor with yellowish color. There have been, however, some rare cases where the rectal carcinoid tumor was not easily diagnosed because of its atypical feature. We report a case of atypical rectal carcinoid tumor misdiagnosed as rectal cancer on endoscopic finding: this atypical gross morphology on endoscopy may be due to atypical histopathologic findings.
