Neostigmine can successfully decompress patients with acute colonic pseudo-obstruction (ACPO) who are unresponsive to conservative therapy. However, neostigmine is contraindicated in renal failure, so it is underused in ACPO patients with renal failure who would be otherwise appropriate candidates. We described the first successfully treated case of acute kidney injury (AKI) with neostigmine in a patient with ACPO. A 72-year-old man who underwent a coronary artery bypass graft surgery 11 days prior presented to the emergency room with abdominal distension, peripheral edema, and dyspnea on exertion. Plain abdominal radiographs and abdomen computed tomography scan showed diffuse colonic dilatation without obstruction. Serum creatinine level was increased five-fold over baseline. We diagnosed the patient as ACPO with AKI. With conservative treatment, renal function failed to improve because the ACPO was not corrected. Administration of neostigmine rapidly resolved ACPO and renal function, avoiding more invasive procedures such as colonoscopic decompression and hemodialysis. Neostigmine appears to be an effective and safe treatment option for ACPO patients with renal failure. Prospective large-scale studies should be carried out to determine the safety and efficacy of neostigmine in ACPO patients with renal failure.

PURPOSE: Sphincter preservation is one of the main goal in the treatment of rectal cancer, but surgical management of cancer of the lower third of the rectum continues to evolve. The aim of this study was to evaluate the oncologic safety and to assess the functional results of coloanal anastomosis following ultra low anterior resection (CAA/ uLAR) in distal rectal cancer. METHODS: Thirty-six patients underwent coloanal anastomosis following ultralow anterior resection between January 2000 and February 2005. Main operative techniques were total mesorectal excision with autonomic nerve preservation. Colonic J pouch was made 6 cm in length. All patients were followed up for fecal incontinence and frequency of bowel movement after diverting ileostomy closure. All patients were evaluated for local or systemic recurrences. RESULTS: The mean age of the patients was 58.7 (34~82) years. The median follow-up period was 24.5 (6~55) months. The types of anastomosis were straight anastomosis (n=25), colonic J pouch formation (n=10) and coloplasty (n=1). The twenty-nine patients of thirty-one patients underwent diverting ileostomy were performed ileostomy repair. The twenty-two patients had frequency after ileostomy repair. There is no statistical correlation of reservoir type and frequency (P=0.604). But the relationship between adjuvant radiation and frequency is statistically correlated (P=0.012). Postoperative complications were anastomotic leakage (n=5), but mostly radiological minor leakage, transient paralytic ileus (n=2), and anastomotic stenosis (n=1). The local recurrence rate is 3% and systemic recurrence occurred in 5 patients (14%), most patients were in Astler-Coller stage C. CONCLUSIONS: Ultralow anterior resection and coloanal anastomosis in low lying rectal cancer did not seem to affect recurrence. This procedure has poor functional outcome in early period but normal continence and acceptable frequency of bowel movements can be obtained at 1 year after operation.
