Expectations and outcomes with gastric bypass surgery.

BACKGROUND: Bariatric surgery is widely accepted as the effective treatment option for morbid obesity. However, the extant literature does not provide mental health clinicians with consistent guidance for evaluating candidates for surgery, nor for preparing patients for postsurgical adjustment. Among both bariatric clinicians and patients, there are commonly endorsed expectations about who will do well postoperatively and what the psychosocial impact of the surgery and weight loss will be. The current study surveyed our patient population regarding the accuracy of these expectations. METHODS: Medical charts were reviewed and surveys mailed to all 194 patients who had undergone the Roux-en-Y gastric bypass (RYGBP) at University of New Mexico Hospital prior to April 2003. Surveys explored patients' expectations and actual experiences with RYGBP and the subsequent changes in their physical and psychosocial status. RESULTS: Completed surveys received from 47.9% of the patients reported significant improvements in physical health, emotional status, and binge eating. These improvements were seen across the entire sample, regardless of the presence of preoperative psychological distress, and were unrelated to the degree of weight loss. Professional and non-romantic relationships benefited from the impact of weight loss, but romantic relationships appeared unaffected. There were no significant changes in occupational status. CONCLUSION: The impact of bariatric surgery appears sufficiently potent to negate whatever preoperative differences might otherwise affect weight management. It may be time for the field to cease its search for surgical outcome predictors and focus instead on improving postoperative support.

Stapled-wedge Collis gastroplasty for the shortened esophagus.

BACKGROUND: Minimally invasive Collis gastroplasty is an established technique for managing the shortened esophagus. The purpose of this report is to describe our new technique, the wedge gastroplasty, and report the short-term outcomes. METHODS: All patients (n = 143) undergoing laparoscopic fundoplication from May 2000 to March 2001 were assessed intraoperatively for shortened esophagus. After mediastinal dissection, 15 patients with inadequate intraabdominal esophageal length underwent wedge gastroplasty. Preoperative symptoms, operative times, and short-term outcomes were evaluated. RESULTS: Mean operative time was 184 +/- 36 minutes (range 138 to 258). There was 1 cervical esophageal tear from bougie passage and no other minor or major complications. At 6 weeks, there was more improvement in esophageal symptoms compared with extraesophageal symptoms. CONCLUSIONS: Wedge gastroplasty is effective in decreasing symptoms in patients with shortened esophagus and takes less time to perform than other gastroplasty techniques. Further study is needed to assess long-term outcomes.

Prospective randomized clinical trial comparing nitrous oxide and carbon dioxide pneumoperitoneum for laparoscopic surgery.

BACKGROUND: Recent publications demonstrating the safety and advantages of N2O for pneumoperitoneum (PP) prompted us to reconsider N2O as an agent for PP in general surgical laparoscopy. The purpose of this prospective, double-blind, randomized clinical trial was to determine whether N2O PP has any benefits over CO2 PP. STUDY DESIGN: One hundred three patients received N2O (group I, n = 52) or CO2 (group II, n = 51) PP for elective laparoscopic surgery. Heart rate, mean arterial blood pressure, end-tidal CO2, minute ventilation, and O2 saturation were recorded before PP, during PP, and in the recovery room. Postoperative pain medication use was recorded. Pain was assessed by means of visual analog scale (VAS) at postoperative hours 2 and 4, and on day 1. RESULTS: There were no differences between groups I and II in patient age, gender, weight, anesthesia risk (American Society of Anesthesiologists Score > 2), operative time, duration of PP, or length of hospital stay. Mean end-tidal CO2 increase under anesthesia was greater in group II than group I (3.0 versus 0.5 mmHg, p < 0.001) despite a greater mean intraoperative increase in minute ventilation in group II than group I (0.7 versus -0.2 L/min p < 0.001). The patients who had N2O PP had less pain 2 hours postoperatively (VAS: 4.9 versus 5.7, p <0.05), 4 hours postoperatively (VAS: 3.3 versus 5.1, p < 0.01), and 1 day postoperatively (VAS: 1.7 versus 3.5, p < 0.01) than patients who had CO2 PP. Postoperative narcotic or ketorolac use was not statistically different between groups. There were no adverse events related to either N2O or CO2 pneumoperitoneum. CONCLUSIONS: These results suggest that the use of N2O PP has sufficient advantages over CO2 that it should be considered as the standard agent for therapeutic PP.
