- Esophagectomy is considered a high-risk procedure in patients aged 70 years or older. This study evaluates the impact of two age groups (younger than 70 and 70 years or older) on clinical outcome and long-term survival rates following this procedure. This prospective study included survival analysis and clinical evaluations at 3, 6, and 12 months after esophagectomy. All esophagectomy patients undergoing gastric (n = 125), jejunal (n = 10), or colonic (n = 4) reconstructions at our institution from 1984 to 1996 were included. Fifty patients were older than 70 years, 89 were younger, and 120 of these 139 patients had tumors. The overall hospital mortality rate was 1.4% (2 of 139), both in the younger age group. All leaks from anastomoses and grafts were nonfatal, and these problems occurred in seven patients in the younger age group and two in the older group. The mean preoperative weight was 70 kg, and there was a mean weight loss of 5 kg during the first three postoperative months only but none thereafter (P <0.001). This was the same for patients with benign and malignant disorders, and for those aged over or under 70 years. Between 71% and 77% of the patients experienced no dysphagia at the three evaluations during the first postoperative year. The distribution of the different grades of dysphagia was equal in the two age groups at 3-month (P = 0.339) and 12-month (P = 0.669) follow-up. The 12-year survival rate was 28% and the 5-year rate was 31%, and this was correlated to tumor stage (P = 0.002) but not to age over or under 70 years (P = 0.299). The clinical outcome was the same regardless of whether patients were over or under 70 years of age. Tumor stage but not age over 70 years was the major predictive factor for long-term survival.

- The excluded stomach after Roux-en-Y gastric bypass (RYGBP) cannot be readily examined by endoscopy for obvious anatomic reasons. Thus it is difficult to monitor possible changes in the gastric mucosa. However, the type and severity of gastritis can now be assessed by a combination of serologic tests: pepsinogen I and antibodies to Helicobacter pylori and H,K-ATPase. Morbidly obese patients were examined before and 1 to 4 years after surgery. A group of 34 patients (mean age 39 years, BMI 44 kg/m2) underwent RYGBP, another group of 30 patients (mean age 42 years, BMI 44 kg/m2) had simple gastric restriction and served as control subjects. All patients, except one in the control group, had normal titers of pepsinogen I before surgery. One year after RYGBP, pepsinogen I levels were significantly reduced, as compared to the control group (P<0.0001), and remained low throughout the study. The control group had stable pepsinogen I levels. In both groups, few patients had increased titers of H. pylori or H,K-ATPase antibodies, but these abnormalities remained unchanged. Low pepsinogen I levels, similar to those we observed in our RYGBP patients, have been linked to chronic atrophic gastritis. However, the absence of food stimulation in the excluded stomach could also be a reason for the low pepsinogen I levels. © 2003 The Society for Surgery of the Alimentary Tract, Inc.

- In the treatment of morbid obesity, simple gastric restrictive methods such as silicone adjustable gastric banding, vertical banded gastroplasty, and nonadjustable gastric banding often fail to control weight in the long run or give rise to intolerable side effects. Here we review our results from conversion of such failures to Roux-en-Y gastric bypass. The study comprised 44 patients (median age 42 years, range 24 to 60 years) who underwent revision surgery in 1996 and 1997. Body mass index at revision was 35 kg/m2 (range 21 to 49 kg/m2). Previous bariatric procedures included silicone adjustable gastric banding (n = 26), vertical banded gastroplasty (n = 13), and gastric banding (n = 5). The most common reasons for conversion after silicone adjustable gastric banding and nonadjustable gastric banding were band erosion (n = 12) and esophagitis (n = 11). Staple line disruption (n = 12) with subsequent weight loss failure was the primary cause after vertical banded gastroplasty. There were no postoperative deaths or anastomotic leaks. One patient underwent reexploration because of an infected hematoma. Reflux symptoms and vomiting resolved promptly. At global assessment 2 years later, 70% of the patients were very satisfied. Median body mass index had decreased to 28 kg/m2 (range 18 to 42 kg/m2). No patient was lost to follow-up. As reported previously, failure after vertical gastric banding can be treated by conversion to Roux-en-Y gastric bypass with good results. In this study we found that failure after silicone adjustable gastric banding can be treated successfully with Roux-en-Y gastric bypass as well.
