We experienced a case of acute urinary retention after an elective cesarean section. In this case, an epidural catheter was inserted for the postoperative pain relief, and we had to rule out anesthetic complications including epidural hematoma. After careful investigation, sacral herpes zoster was found to be responsible for urinary retention. Early administration of antiviral agent was started and the outcome was good. As various factors may lead to postpartum urinary disorders, we should be careful not to miss serious complications.

BACKGROUND Colorectal neuroendocrine carcinoma (NEC) is a rare tumor that demonstrates aggressive growth pattern with ingrowth into the tract, metastasis to the other organs, and invasion to the surrounding organs;these clinical characteristics result in poor prognosis. Surgical resection appears as an effective approach;however, because it is difficult to accurately diagnose NEC during the early stage and owing to its aggressive growth pattern, development of a reliable standard chemotherapy regimen and management strategies are essential. CASE SUMMARY Here, we report the case of patient with NEC showing an aggressive growth pattern that resulted in the rupture of the tumor to the outside the colon after stenting of the internal colonic stenosis. In addition, the tumor invaded into the duodenum, thereby causing duodenal stenosis that required an additional stent in the duodenum. This aggressive growth pattern is one of the main features of the NEC that is different from adenocarcinoma. To clarify the clinical characteristics, we reviewed 60 recently reported cases, including data on tumor location, size, treatment, and prognosis. CONCLUSION We consider that the information presented here is of great significance for the diagnosis, treatment, and management of symptoms of the patients with NEC.

After a long history of Dark Age of adjuvant chemotherapy for gastric cancer, definite evidences of survival benefit from adjuvant treatment have been reported since 2000 s. These survival benefits are likely attributed to something new approach different from pervious studies. In 2001, South West Oncology Group INT0116 trial yielded survival benefit in curatively resected gastric cancer patients with postoperative chemoradiotherapy [5-fluorouracil(5-FU) + Leucovorin + radiotherapy], followed by positive result by MAGIC Trial, employing perioperative(pre- and postoperative chemotherapy with Epirubicin, cisplatin(CDDP), 5-fluorouracil(ECF) regimen in patients with curative resection. A novel drug [S1: ACTS-GC(Adjuvant chemotherapy trial of TS-1 for gastric cancer) in 2007], or new drug combination chemotherapys [CDDP + 5-FU: FNCLCC/FFCD(Federation Nationale des Centres de Lutte contre le cancer/Federation Francophone de Cancerologie Digestive) in 2011, Capecitabine + Oxaliplatin: CLASSIC in 2012] also produced positive results in terms of improved prognosis. Neoadjuvant or perioperative chemotherapy, novel anti-cancer drugs, and chemoradiotherapy might be the key words to develop further improvement in the adjuvant treatment of resectable gastric cancer. Moreover, it is not new but still true to stress the importance of D2 surgery as the baseline treatment in order to minimize the amount of residual tumor after surgery.

To compare the tolerability and quality of bowel cleansing between 2 L polyethylene glycol (PEG) and reduced-dose sodium phosphate (NaP) tablets as a preparation for colonoscopy. METHODSTwo hundred patients were randomly assigned to the PEG or NaP groups at the same ratio. The NaP group patients took 30 tablets with 2 L of clear liquid, while the PEG group patients took 2L of PEG. Tolerability was assessed by a questionnaire about taste, volume, and the overall impression. The bowel cleansing quality was evaluated by colonoscopists. RESULTSAlthough NaP showed better tolerability in terms of taste, volume and overall impression (P < 0.01, P < 0.01 and P = 0.02, respectively), the overall cleansing quality was better in the PEG group (P < 0.01). A subgroup analysis, stratified by sex and age, indicated that NaP was associated with better tolerability and equivalent bowel cleansing quality in females of < 50 years of age. CONCLUSIONDespite the better tolerability, the use of 30 NaP tablets with 2 L of clear liquid should be limited due to its lower cleansing quality; however, in certain cases the regimen may deserve consideration, particularly in cases involving young women.

The prevalence of diverticular diseases of the colon, including severe and persistent bleeding in Eastern countries, has increased in the last decades. The bleeding from colonic diverticula is the most common cause of acute lower gastrointestinal bleeding. Herein, we report four cases of severe and persistent bleeding of colonic diverticular disease that could be treated with a high concentration barium enema. These four cases showed a similar pattern of bleeding whose source could not be identified. Colonoscopy revealed fresh blood in the entire colon and many diverticula were noted throughout the colon. No active bleeding source was identified, but large adherent clots in some diverticula were noted. After endoscopic and angiographic therapies failed, therapeutic barium enema stopped the severe bleeding. These patients remained free of re-bleeding in the follow-up period (range 17-35 mo) after the therapy. We report the four case series of therapeutic barium enema and reviewed the literature pertinent to this procedure.
