Computed tomographic evaluation of the excluded stomach in gastric bypass.

Eleven patients who had gastric bypass operations were examined with computed tomography to evaluate the status of the excluded stomach. Three of the patients had dilated excluded stomachs that accounted for the patients' symptomatology. As an upper gastrointestinal series cannot delineate the excluded stomach, computed tomography is the examination of choice for such an evaluation.

The fetal stomach circumference/abdominal circumference ratio: a possible parameter in assessing fetal stomach size.

Nonvisualized, dilated or even a small fetal stomach can be associated with a variety of anomalies and poor fetal outcome. Therefore, we attempted to evaluate the stomach circumference (SC)/abdominal circumference (AC) ratio to assess normal limits of fetal stomach size. A total of 363 fetuses ranging from 15 to 39 weeks' gestation were prospectively evaluated with ultrasonography. The SC was measured from a plane that is perpendicular to the fetal longitudinal axis at the level where the largest axial circumference of the stomach was obtained using a digitizer. The AC was also measured at the same section and the ratio was calculated by dividing the SC by the AC and multiplying by 100. The SC increased linearly from 15 to 24 weeks and showed fluctuations in size thereafter to 39 weeks. A strong correlation was noted between gestational age and both SC (r: 0.842, P < 0.0001) and AC (r: 0.975, P < 0.0001). The SC/AC ratio was normally distributed with a mean of 20.4 +/- 3.9% and ranged between 14.8% and 27.03% throughout pregnancy (r: 0.021, P > 0.05). Although the fetal stomach is a dynamically changing organ, the SC/AC ratio can be considered as a potentially useful parameter in assessing fetal stomach size.

Early removing gastrointestinal decompression and early oral feeding improve patients' rehabilitation after colorectostomy.

AIM: To evaluate the feasibility, safety, and tolerance of early removing gastrointestinal decompression and early oral feeding in the patients undergoing surgery for colorectal carcinoma. METHODS: Three hundred and sixteen patients submitted to operations associated with colorectostomy from January 2004 to September 2005 were randomized to two groups: In experimental group (n=161), the nasogastric tube was removed after the operation from 12 to 24 h and was promised immediately oral feeding; In control group (n=155), the nasogastric tube was maintained until the passage of flatus per rectum. Variables assessed included the time to first passage of flatus, the time to first passage of stool, the time elapsed postoperative stay, and postoperative complications such as anastomotic leakage, acute dilation of stomach, wound infection and dehiscense, fever, pulmonary infection and pharyngolaryngitis. RESULTS: The median and average days to the first passage of flatus (3.0+/-0.9 vs 3.6+/-1.2, P<0.001), the first passage of stool (4.1+/-1.1 vs 4.8+/-1.4, P<0.001) and the length of postoperative stay (8.4+/-3.4 vs 9.6+/-5.0, P<0.05) were shorter in the experimental group than in the control group. The postoperative complications such as anastomotic leakage (1.24% vs 2.58%), acute dilation of stomach (1.86% vs 0.06%) and wound complications (2.48% vs 1.94%) were similar in the groups, but fever (3.73% vs 9.68%, P<0.05), pulmonary infection (0.62% vs 4.52%, P<0.05) and pharyngolaryngitis (3.11% vs 23.23%, P<0.001) were much more in the control group than in the experimental group. CONCLUSION: The present study shows that application of gastrointestinal decompression after colorectostomy can not effectively reduce postoperative complications. On the contrary, it may increase the incidence rate of fever, pharyngolaryngitis and pulmonary infection. These strategies of early removing gastrointestinal decompression and early oral feeding in the patients undergoing colorectostomy are feasible and safe and associated with reduced postoperative discomfort and can accelerate the return of bowel function and improve rehabilitation.

Percutaneous gastrostomy for treating dilatation of the bypassed stomach after bariatric surgery for morbid obesity.

OBJECTIVE: Retrospective analysis was performed to determine the safety and effectiveness of percutaneous gastrostomy for treating distention of the bypassed stomach after gastric bypass for morbid obesity. MATERIALS AND METHODS: Eight patients with morbid obesity and Roux-en-Y gastric bypass underwent percutaneous radiologic gastrostomy for postoperative decompression of the bypassed stomach. Four patients underwent gastrostomy on the fourth day after surgery: two in the early postoperative period (< or = 30 days after surgery) and two in the late postoperative period (6, 11 months after the procedure). Procedures were performed using combinations of fluoroscopic, CT, and sonographic guidance. T-tacks and a variety of locking pigtail drainage catheters were placed in seven patients. RESULTS: Gastrostomy placement was technically successful in all patients. Seven of eight patients experienced resolution of symptoms. Gastrostomy catheters were in place for a mean of 31 days. Two complications occurred. Periprocedural peritonitis in one patient with underlying small-bowel obstruction required surgical intervention. One wound infection was treated with antibiotics and local wound care. No catheters became dislodged or obstructed. Four patients treated during the early postoperative period had resolution of symptoms after tube placement and recovered uneventfully. Three of four patients presenting during the intermediate or late postoperative periods had temporary resolution of symptoms, but all eventually required surgical intervention. CONCLUSION: In the absence of complete small-bowel obstruction, percutaneous radiologic gastrostomy provides safe and effective decompression of the excluded gastric remnant after Roux-en-Y gastric bypass. Gastrostomy tube placement after the early postoperative period is temporizing, with surgical intervention eventually required.

Gastric perforation caused by a bulimic attack in an anorexia nervosa patient: report of a case.

We report a rare case of gastric perforation due to a bulimic attack in a 17-year-old girl suffering from anorexia nervosa. She was admitted to our hospital with the chief complaint of abdominal pain following bulimia. Initially, her symptoms were reduced after drainage using a nasogastric tube. Eight hours later, however, she fell into a state of preshock. Abdominal radiography revealed subphrenic free air. We diagnosed the patient as having diffuse peritonitis. At laparotomy, the stomach was dilated and necrotic with perforation. Almost the entire stomach was resected. Postoperatively, the patient recovered uneventfully. We should therefore be aware of this condition when treating patients with anorexia nervosa who complain of abdominal pain.

Megaesophagus and aspiration pneumonia secondary to gastric ulceration in a foal.

A 3-month-old foal with a history of persistent fever and leukocytosis was found to have pneumonia, ulceration of the squamous portion of the stomach, and dilatation of the distal portion of the esophagus. The foal was euthanatized and necropsied. The distal portion of the esophagus was severely dilated, and there was severe ulceration and mural thickening of the stomach at the cardia. Because of the severe gastric ulceration and mural thickening, the gastroesophageal junction was fixed in an open position, permitting gastroesophageal reflux. The megaesophagus and pneumonia were considered to have resulted from chronic gastroesophageal reflux.
