Recent pressures to decrease the cost of medical care have mandated preoperative outpatient bowel preparation (OBP) for elective colorectal surgery without any data documenting equivalent quality of care. This study examined the safety and efficacy of OBP compared with inpatient bowel preparation (IBP). ⋯ Outpatient bowel preparation for elective colorectal surgery is safe and effective. It offers shorter hospital stay, and, therefore, potentially reduces medical care cost. Patients with multiple medical problems may not tolerate extensive fluid shifts; therefore, other preoperative arrangements, such as inpatient or outpatient intravenous fluid therapy, need to be considered to minimize complications that may outweigh potential cost savings.

Obstetric trauma and excessive defecatory straining with perineal descent may lead to pudendal neuropathy with bilateral increase in pudendal nerve terminal motor latencies (PNTML). We have frequently observed unilateral prolongation of PNTML. Diagnostic and therapeutic implications of unilateral pudendal neuropathy are discussed. ⋯ A significant number of patients with pelvic floor disorders have only unilateral pudendal neuropathy. Patients with unilaterally prolonged PNTML should be considered to have pudendal neuropathy, despite normal value for mean PNTML. This fact may be relevant in planning surgical treatment and in predicting prognosis of patients with sphincter injuries.

Two hundred fifty-eight consecutive nonsedated colonoscopies were prospectively evaluated over an 18-month period. The cecum was intubated in 250 cases (97 percent). Polypectomies or biopsies were performed in 77 cases (31 percent). Indications for colonoscopy included history of polyps (32 percent), hematochezia (28 percent), family history of colon cancer (16 percent), prior history of colon cancer (9 percent), change in bowel habits (12 percent), abnormal flexible sigmoidoscopy (6 percent), and inflammatory bowel disease (3 percent). ⋯ Several series have studied nonsedated endoscopic upper and lower gastrointestinal evaluations. None, however, have evaluated patient comfort and satisfaction. In our prospective series of 258 consecutive nonsedated colonoscopies, we found the procedure to be safe, effective, and well accepted.

Comparative Study
Accuracy of serum C-reactive protein measurements in diagnosis of acute appendicitis compared with surgeon's clinical impression.
Diagnosis of acute appendicitis is established generally by the surgeon's clinical impression. Today, negative laparotomy rate because of clinical diagnosis is still 15 to 25 percent. ⋯ We found that elevated serum CRP levels support surgeon's clinical diagnosis. We recommend CRP measurement as a routine laboratory test in patients with suspected diagnosis of acute appendicitis.

Toxic megacolon is a rare complication of pseudomembranous enterocolitis. We reviewed our recent experience with this complication. ⋯ Toxic megacolon complicating pseudomembranous enterocolitis is a serious problem that carries a high morbidity and mortality rate, regardless of treatment.
