It has been suggested that division of the short gastric vessels (SGV) provides a more floppy Nissen fundoplication, for the treatment of reflux disease. The aim of the study was to assess whether Nissen fundoplication with division of SGV is associated with improved clinical outcome and laboratory findings.Fifty-six consecutive patients with gastroesophageal reflux disease (GERD) were randomly assigned to have a laparoscopic Nissen fundoplication either with division (24 patients; 15 men; mean age 51 +/- 15 years) or without division (32 patients; 23 men, mean age 47 +/- 14 years) of the SGV. Preoperative and postoperative investigation included clinical assessment, esophagoscopy, esophagogram, esophageal manometry, and 24-hour ambulatory esophageal pH monitoring.Division of the SGV resulted in a significant increase of the operating time (P0.0001). The operation abolished reflux in both groups. Also, both types of Nissen fundoplication significantly increased the amplitude of peristalsis at distal esophagus (division group: from 56 +/- 20 mm Hg to 64 +/- 25 mm Hg, P = 0.01; nondivision group: from 65 +/- 27 mm Hg to 75 +/- 26 mm Hg, P0.001) and the lower esophageal sphincter pressure (division group: from 16 +/- 10 mm Hg to 24 +/- 7 mm Hg, P0.001; nondivision group: from 22 +/- 8 mm Hg to 28 +/- 5 mm Hg, P0.001). No differences in the incidence of postoperative severe dysphagia (division group: 5 of 24; nondivision group: 3 of 32) and overall esophageal transit were accounted between groups. However, division of the SGV was associated with a significant increased incidence of gas-bloating syndrome (division group, 13 of 24, versus nondivision group, 9 of 32, P = 0.02).Division of the SGV at laparoscopic Nissen fundoplication for GERD does not improve clinical outcome and laboratory findings, while it is associated with prolongation of the operating time and increased incidence of gas-bloating syndrome.

background Exclusion of the duodenum by means of transection and Roux-Y duodenojejunostomy has been practiced for the treatment of complicated duodenal diverticulum. However, this method does not divert bile away from the diverticulum, hence the possibility of pancreaticobiliary complications is not eliminated. methods Roux-Y Choledochojejunostomy and duodenojejunostomy, for the diversion of bile and food, has been applied for the treatment of pancreaticobiliary complications of duodenal diverticulum in 4 patients. Postoperatively, all patients had endoscopy, HIDA-scintigraphy for the measurement of enterogastric reflux, and assessment of gastric emptying. results One year postoperatively, there were no recurrent symptoms of cholangitis or pancreatitis, no anastomotic ulceration was found on endoscopy, there were no complaints of gastric stasis, and enterogastric reflux was not significant. conclusions Roux-Y Choledochojejunostomy and duodenojejunostomy for the treatment of the complicated duodenal diverticulum is associated with satisfactory results. Postoperative symptoms attributed to anastomotic ulceration, bile reflux, or gastric stasis are also absent.

Background It has been confirmed that erythromycin has gastrokinetic properties of enhancing gastric emptying both in health and disease. The objective of the present study was to investigate any possible effect of erythromycin on esophageal motility. Methods In 14 healthy subjects, standard esophageal manometry was performed before and after the intravenous administration of 200 mg of erythromycin. The calculated manometric parameters of esophageal motility were the lower esophageal sphincter (LES) pressure; the amplitude and duration of peristalsis at 5, 10, and 15 cm proximal to the LES; and the velocity and strength of peristalsis at 5 cm proximal to the LES. Results Erythromycin significantly increased the LES pressure ( P P = 0.002), duration ( P = 0.003), strength ( P = 0.014) and velocity ( P = 0.008) of peristalsis at 5 cm proximal to LES. Erythromycin also increased the amplitude of peristalsis at 10 cm proximal to the LES ( P = 0.035). Conclusion Erythromycin affects the motility of the distal esophagus.

It has been shown that truncal vagotomy with pyloroplasty (TVP), but not highly selective vagotomy (HSV), delays the onset, decreases the extent, and changes the pattern of gallbladder emptying. The aim of the present study was to investigate any alterations in gallbladder emptying after a variety of antiulcer gastric surgery, by milk-technetium 99m (99mTc)-dimethyl iminodiacetic acid (HIDA) scintigraphy. After excluding the cases with spontaneous gallbladder evacuation before milk ingestion, there were 26 controls, 41 duodenal ulcer (DU) patients, 22 after HSV (15 prospective cases), 50 after TVP (23 prospective cases), 8 after TV with gastrojejunostomy (TV-GJ), 10 after Billroth I gastrectomy, and 29 after Billroth II gastrectomy. None of the patients with gastrectomy had additional vagotomy. TVP significantly delayed the onset and decreased the rate of gallbladder emptying as compared with the control, DU, HSV, and Billroth I groups. TVP also changed the pattern of emptying in 20% of the cases (sequential emptying and refilling events). Antiulcer operations excluding the duodenum (TV-GJ and Billroth II) further reduced the rate of gallbladder emptying as compared with (1) control, DU, HSV, and Billroth I groups (P0.0001) and (2) TVP (P0.001). Onset of gallbladder emptying was not affected by Billroth II gastrectomy, but was significantly delayed by TV-GJ (P0.001). The latter two operations also significantly changed the pattern of gallbladder emptying, exhibiting sequential emptying and refilling events, in most cases (P0.01 versus TVP). In conclusion, all antiulcer procedures, except HSV, greatly disturb the pattern, the onset, and the rate of gallbladder emptying. Truncal vagotomy seems to disrupt vagally mediated preduodenal mechanism, resulting in delayed onset and reduced rate, whereas duodenal exclusion by gastrojejunostomy results in severely decreased rate of gallbladder emptying.
