Polyethylene glycol electrolyte lavage solution was compared with a 10 percent mannitol solution for preoperative colonic cleansing. Eighty patients were prepared randomly with one of these solutions on the afternoon prior to surgery. Colonic cleansing was better with polyethylene glycol electrolyte lavage (90 percent optimal cleansing vs. 75 percent). Analysis of hematologic, biochemical, and weight changes before and after the bowel preparation, demonstrated a mild subclinical dehydration with the use of mannitol. Evaluation of patient tolerance demonstrated more nausea, cramps, and abdominal pain with mannitol. Other symptoms were similar with both preparations. Colonic hydrogen gas was sampled during surgery, and two patients in the mannitol group had combustible levels. This study confirms that both 10 percent mannitol and polyethylene glycol electrolyte lavage are safe, effective methods of preoperative bowel cleansing. Better cleansing, patient tolerance, and lower hydrogen gas level make polyethylene glycol electrolyte lavage the preferred method.

An oral colonic lavage solution containing sodium sulfate and polyethylene glycol was compared with whole-gut irrigation using saline via a nasogastric tube in a randomized blinded study of 34 consecutive well-matched patients undergoing elective colorectal surgery. Both methods were safe and rapid. Patients receiving oral colonic lavage, however, had significantly less (P less than 0.05) water retention, overall distress, cramps, and other complaints. No significant differences were found with regard to fullness, nausea, and rectal discomfort. The bowel cleansings were equally adequate, and most patients achieved a good-to-excellent preparation. Surgical complications appeared not to be related to the preparation used, and wound sepsis were equally frequent. Oral colonic lavage proved to be the most attractive preoperative cleansing method.

In the search for a superior alternative to conventional bowel preparation which often gives unsatisfactory results in children, we have introduced whole-gut irrigation for pediatric use. After a pilot study on 15 children during which adjustments on the technique were made, we settled on an intensive regimen with some notable modifications from conventional adult practice: the use of warm Hartmann's solution, a relatively large fluid load (mean volume 5.3 l/kg body weight, range 3.0 - 12.0 l/kg) and a rapid infusion rate (1.5 ml/kg/min). We then evaluated its safety, effectiveness, and acceptability prospectively on 45 patients undergoing colonoscopy or colorectal surgery, age ranging from 4 months to 11 years, with a mean of 3.9 years. Subjective complaints were mild and included nausea/vomiting, 12 cases (26.7 percent); abdominal colic, two (4.4 percent); and distending discomfort, three (6.7 percent). There was a mean weight gain of 4.0 percent but no gross electrolyte disturbances. Results of bowel preparation were satisfactory in 33 (73.3 percent), adequate in ten (22.2 percent) and poor in two (4.4 percent). Compared with our previous method, in which inadequate preparation occurred in 4/20 patients, (20 percent) by conventional measures, whole-gut irrigation represents a statistically significant improvement (P less than 0.05). In addition, whole-gut irrigation shortened hospital stay and obviated the traditional need of two to three days' dietary restrictions.

Strictureplasty recently has been advocated in the treatment of obstructive strictures of the small bowel in patients with Crohn's disease. In contrast to conventional methods of treatment, such as conservative therapy with total parenteral nutrition (TPN) or surgical resection of the involved bowel, strictureplasty eliminates the obstruction without loss of small bowel. The possibility of creating a short-bowel syndrome is of special concern in patients with diffuse Crohn's jejunoileitis. These patients usually present for surgery with chronic obstruction, anemia, weight loss, and malnutrition with folate and other vitamin deficiencies. The authors report the results of 12 strictureplasties for extensive Crohn's jejunoileitis in three patients presenting with chronic obstruction secondary to multiple small-bowel strictures. Both Heineke-Mikulicz and Finney strictureplasties were performed. In two patients, resection of an acutely inflamed phlegmonous segment was also performed. Symptoms (pain, abdominal distention, and nausea) were markedly improved postoperatively in all patients. Nutritional parameters, including serum albumin and total lymphocyte count, improved postoperatively. Dramatic rises in weight were noted also. All three patients were symptom-free six months postoperatively.

Three cases of benign duodenocolic fistula are presented, and the diagnosis and treatment reviewed. Patients with benign duodenocolic fistulas usually complain of diarrhea, and occasionally nausea and feculent vomiting. Physical examinations are nonspecific, revealing wasting from the chronic diarrhea. Barium enemas are usually diagnostic. Therapy consists of excision of the fistula and repair of the duodenal and colonic defects.

A 50-year-old woman presented with a long history of nausea, abdominal pain, weight loss, and intermittent watery diarrhea. All investigations were negative except for the finding, on five separate colonoscopic biopsies, of a layer of band-like collagen beneath the surface epithelium, diagnostic of collagenous colitis.

Severe nausea and vomiting are common side effects of anti-cancer chemotherapy. 5-HT3 receptor antagonists have been used for the treatment of these gastrointestinal symptoms. The purpose of this study was to examine whether specific changes in serotonin dynamics occurred in the gastrointestinal tract in mice in which Colon-26 adenocarcinoma cells were injected s.c., especially after treatment with cisplatin. The serotonin content of the small intestine of mice inoculated s.c. with Colon-26 adenocarcinoma increased significantly 2 weeks after the inoculation of the tumor cells; this was associated with an increase in tryptophan hydroxylase activity and the number of enterochromaffin cells as compared with control mice. Intravenous injection of cisplatin significantly reduced the serotonin content in the small intestine of Colon-26 tumour-bearing mice but not in control mice. The spontaneous release of serotonin from isolated intestine was not different between Colon-26 tumour-bearing and control mice; however, pretreatment of mice with cisplatin induced two fold increases in serotonin release from duodenum, jejunum and ileum in Colon-26 tumour-bearing mice but not in control mice. These results indicate that a region-specific increase in the number of enterochromaffin cells is observed in the intestine of Colon-26 tumour-bearing mice, associated with an increase in the serotonin content and tryptophan hydroxylase activity. Cisplatin treatment induced the release of serotonin from affected enterochromaffin cells in the gastrointestinal tract, which may be related to the occurrence of nausea in clinical use.

Gastrointestinal complications are frequent in renal transplant recipients and can include oral lesions, esophagitis, peptic ulcer, diarrhea, colon disorders and malignancy. Oral lesions may be caused by drugs such as cyclosporine and sirolimus, by virus or fungal infections. Leukoplakia may develop in patients with Epstein-Barr virus (EBV) infection. The commonest esophageal disorder is represented by fungal esophagitis usually caused by candida. A number of patients may suffer from nausea, vomiting and gastric discomfort. These disorders are more frequent in patients treated with mycophenolate mofetil (MMF). Peptic ulcer is more rare than in the past. Patients with a history of peptic ulcer are particularly prone to this complication. Other gastroduodenal disorders are caused by cytomegalovirus (CMV) and herpes simplex infection. Diarrhea is a frequent disorder which may be caused by pathogen microorganisms or by immunosuppressive agents. The differential diagnosis may be difficult. Colon disorders mainly consist of hemorrhage, usually sustained by CMV infection, or perforation which may be caused by diverticulitis or intestinal ischemia. Colon cancer, anal carcinoma, and EBV-associated lymphoproliferative disorders are particularly frequent in transplant recipients. A particular gastric lymphoma called mucosa-associated lymphoid tissue (MALT) lymphoma may develop in renal transplant patients. It usually responds to the eradication of Helicobacter pylori.

Serotonin (5-HT) is most commonly thought of as a neurotransmitter in the central nervous system. However, the predominant site of serotonin synthesis, storage, and release is the enterochromaffin cells of the intestinal mucosa. Within the intestinal mucosa, serotonin released from EC cells activates neural reflexes associated with intestinal secretion, motility, and sensation. Two important receptors for serotonin that are located in the neural circuitry of the intestines are the 5-HT(3) and 5-HT(4) receptors; these are the targets of drugs designed to treat gastrointestinal disorders. 5-HT(3) receptor antagonists are used to treat nausea and emesis associated with chemotherapy and for functional disorders associated with diarrhea. 5-HT(4) receptor agonists are used as promotility agents to promote gastric emptying and to alleviate constipation. Because of the importance of serotonin in normal gut function and sensation, a number of studies have investigated potential changes in mucosal serotonin signaling in pathologic conditions. Despite the inconsistencies in the current literature, changes in serotonin signaling have now been demonstrated in inflammatory bowel disease, irritable bowel syndrome, postinfectious irritable bowel syndrome, and idiopathic constipation. Emerging evidence has led to many contradictory theories regarding serotonin signaling and its roles in the pathology of gut disorders. This review summarizes the current medications affecting serotonin signaling and provides an overview of our current knowledge of the changes in serotonin that occur in pathologic conditions.

Evidence-based perioperative care plans after colorectal surgery serve to improve quality outcome, decrease complications, and reduce medical cost. The benefits of routine nasogastric decompression and prolonged enteral restriction after bowel resection are not supported in this new era of evidence-based surgical care. Prophylactic nasogastric decompression fails to improve bowel function, length of stay, and prevent anastomotic leak, wound complications (infection, fascial dehiscence, incisional hernia), pulmonary complications (atelectasis, aspiration, pneumonia, fever, pharyngolaryngitis), and abdominal discomfort (distension, nausea, vomiting). Patients have earlier return of bowel function without the use of a nasogastric tube (NGT). Early refeeding within 24 hours after bowel resection is well tolerated in 80 to 90% of patients, and associated with earlier hospital discharge, decreased risk of infection, and improved postoperative hyperglycemic control. Abdominal discomfort is the most common complication observed in patients treated with early feeding and without a NGT, but does not result in higher therapeutic nasogastric intubation, postoperative ileus, aspiration, or other complications. The use of multimodal adjuncts in combination with these guidelines should be considered to improve outcome. The current literature is reviewed with suggestions for achieving better outcomes after colorectal resection.
