Shared medical appointments: new concept for high-volume follow-up for bariatric patients.

BACKGROUND: Shared medical appointments (SMAs) are a new model in patient care. This model was designed to improve patients' access to their physicians and improve physician productivity. The aim of this study was to evaluate patient satisfaction with SMAs after bariatric surgery. METHODS: The medical records of consecutive patients who were followed up after bariatric surgery were retrospectively reviewed. The type of bariatric surgery and type of medical appointment were recorded, as were the patients' replies to the evaluation questionnaires in the SMA group. RESULTS: From April 2004 to December 2004, 277 individual visits were conducted; 242 visits for patients who underwent Roux-en-Y gastric bypass and 35 visits for patients who underwent laparoscopic gastric banding. Thirty-three SMAs occurred during that period--28 SMAs for patients who underwent Roux-en-Y gastric bypass and 5 SMAs for patients who underwent laparoscopic gastric banding. Of the patients who initially participated in an SMA, 91% scheduled a subsequent SMA, and 96% indicated that they would recommend SMAs to others. On a scale of 1 to 5 (1, poor and 5, excellent), patients graded their overall experience with SMAs as 4.5. Other parameters in the questionnaire all ranked between 4 and 5. The average waiting period for an appointment before the implementation of SMAs was 57.7 days (range 50-65) for new patients and 50 days (range 20-72) for former patients. After the implementation of SMAs, the average waiting period was 25 days (range 8-42) for new patients (P = 0.0046) and 20.3 days (range 0-42) for former patients (P = 0.06). CONCLUSION: The SMA offers the patient prompt access to medical care, enables high-volume follow-up, with high satisfaction rates.

Challenges of laparoscopic colectomy in the obese patient: a review.

BACKGROUND: Perioperative care of clinically severely obese patients presents numerous unique challenges. These patients have distinctive issues with regard to cardiovascular, pulmonary, and thromboembolic complications. In addition, hospital equipment must be able to accommodate the body habitus of this population. METHODS: A Medline search using the terms "morbid obesity," "colon resection," "obesity comorbidities," "laparoscopic colectomy," "perioperative challenges," and "risk factors" was performed for English-language articles. Further references were obtained through cross-referencing the bibliography cited in each publication. RESULTS: The authors discussed the most relevant challenges surgeons encounter in the perioperative setting when treating obese patients. COMMENTS: The management of the morbidly obese patient requires meticulous preoperative, intraoperative, and postoperative care. Colorectal surgeons should be familiar with obesity-related problems when treating colorectal disease processes in this patient population. The associated comorbid illnesses in this population, as well as the technical difficulties regularly posed by them, make laparoscopic colectomy a more challenging procedure than normally encountered in the nonobese patient population.

Novel approaches in the treatment of fecal incontinence.

The availability of novel techniques to treat end-stage FI gives hope for a better quality of life in patients who were traditionally treated by a permanent stoma. The diversity of causes of FI and the different modes of action of the various treatment modalities mandate a tailored, individualized approach in each case. A meticulous preoperative evaluation process is imperative in the course of the decision-making of which procedure to perform, with full awareness that a stoma still may be the best option for some patients who have end-stage FI.

Achalasia after vertical banded gastroplasty for morbid obesity: A case report.

Achalasia is an unusual motility disorder that can be seen in conjunction with obesity. The prevalence of achalasia is unknown in obese patients and when present, the clinical characteristics are atypical. We report a case of achalasia that was diagnosed 13 years after a vertical-banded gastroplasty was performed.

Laparoscopic sleeve gastrectomy as treatment for morbid obesity: technique and short-term outcome.

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) and laparoscopic adjustable gastric banding (LAGB) are the most commonly performed surgical procedures for weight reduction in the United States. Currently, laparoscopic sleeve gastrectomy (LSG) is being explored. The aim of this study was to assess the safety and short-term efficacy of LSG as a treatment option for weight reduction. METHODS: Data of all patients who underwent LSG for treatment of morbid obesity between November 2004 and March 2006 and completed the 3- and 6-month follow-up visits at the time of the study, were retrospectively reviewed. Data collected included demographics, operative time, length of stay, postoperative complications, and degree of weight reduction. RESULTS: Of the 62 patients who underwent LSG performed by two surgeons, the data of 30 patients (7 males and 23 females) were further analyzed. Mean preoperative BMI was 41.4 (33-59) kg/m(2). Mean operative time was 80 min (range 65-130). Mean hospital stay was 3.2 days (range 2 to 25). Mean weight loss at 3 and 6 months following the procedure was 22.7 kg and 30.5 kg respectively, and mean % excess weight loss (EWL) was 40.7 and 52.8, respectively. Three patients were considered to have mild complications, and one patient had a major complication that necessitated surgical intervention. There was no mortality. CONCLUSIONS: In the short-term, LSG is a safe and effective treatment option.

Preoperative thiamine deficiency in obese population undergoing laparoscopic bariatric surgery.

BACKGROUND: Nutritional deficiencies are a recognized complication of bariatric surgery. Thiamine deficiency has been reported as a possible consequence of both restrictive and malabsorptive bariatric procedures. Most of the reported cases occurred after Roux-en-Y gastric bypass (RYGB) surgery; fewer were described after biliopancreatic diversion, vertical banded gastroplasty, or duodenal switch. Adults who have a high carbohydrate intake derived mainly from refined sugars and milled rice are at greater risk of developing thiamine deficiency, because thiamine is absent from fats, oils, and refined sugars. Currently, no reports have evaluated the preoperative thiamine status of bariatric patients. The aim of this study was to evaluate the degree of thiamine deficiency in obese patients before bariatric surgery at our institution. METHODS: The medical records of consecutive patients who underwent laparoscopic RYGB or laparoscopic adjustable gastric banding at our institution between March 2003 and February 2004 were retrospectively reviewed. Patients were selected for this study on the basis of predetermined criteria. Preoperative thiamine levels were retrospectively recorded. Excluded from this study were patients who had been taking multivitamins or other nutritional supplements before surgical intervention, had a history of frequent alcohol consumption, any malabsorptive diseases, or previous restrictive-malabsorptive surgical interventions, such as RYGB, biliopancreatic diversion, or adjustable gastric banding, according to the initial evaluation and questionnaire. RESULTS: Of 437 consecutive patients who underwent laparoscopic RYGB or laparoscopic adjustable gastric banding, 303 were included in the study. Forty-seven patients (15.5%) presented with low preoperative thiamine levels. The mean age and body mass index of these patients was 46 years and 60 kg/m(2), respectively. Male patients presented with greater mean preoperative thiamine levels (3.2 microg /dL) than female patients (2.4 microg/dL). CONCLUSION: Obese patients undergoing bariatric surgery may have significant thiamine deficiency before surgery.

Pelvic outlet obstruction.

Despite the wide variety of definitions and descriptions of constipation, ideally, the diagnostic approach should be uniform. The evaluation process should begin with a careful and thorough patient history and physical exam; appropriate efforts should be made to exclude organic causes of constipation. Patients suffering from pelvic outlet obstruction often respond poorly to conservative treatment. Diagnostic tests include intestinal transit studies, anorectal manometry, defecography, balloon expulsion, and anal sphincter electromyography. For many patients constipation is multifactorial and accordingly, so is the treatment. In our opinion the first line of treatment should be based on conservative measures including adequate intake of fluids, dietary fiber supplementation, and laxatives. Biofeedback training should be offered, particularly to patients with paradoxical puborectalis contraction. Surgical management can, in very limited circumstances, be offered only to those patients with disabling symptoms who have failed other standard therapeutic measures.

Correlation of radiographic and endoscopic evaluation of gastrojejunal anastomosis after Roux-en-Y gastric bypass.

BACKGROUND: Anastomotic stenosis presents as one of the most common late complications in the postoperative period after bariatric surgery. It is often diagnosed by upper gastrointestinal series (UGIS) and/or upper endoscopy (UE). The aim of this study was to determine whether a correlation exists between the Gastrografin UGIS and UE findings in the determination of gastrojejunal anastomotic strictures after Roux-en-Y gastric bypass (RYGB). METHODS: Between July 2001 and October 2003, all medical records of patients who underwent RYGB at our institution were retrospectively reviewed. The medical records of patients who underwent UE because of symptoms suggestive of gastric outlet obstruction and those of patients who were initially evaluated by Gastrografin UGIS before UE were evaluated further. RESULTS: Of 535 morbidly obese patients who underwent RYGB, 52 (9.7%) had UE and were included in this study. The mean number of UEs performed per patient was 2.67. Of these 52 patients, 30 underwent Gastrografin UGIS before UE. The mean diameter of the anastomosis on the first UE was 5.97 mm and on Gastrografin UGIS was 6.83 mm. A good correlation was found between the Gastrografin UGIS and UE findings using Pearson's correlation coefficient (0.44, P = .02) and single linear regression analysis using the endoscopic diameter as the outcome and radiographic findings as the predictor (beta = 0.27, P = .025, 95% confidence interval 0.30-0.49). CONCLUSION: In our study, the Gastrografin UGIS findings correlated positively with the endoscopic gastrojejunal anastomosis findings in patients with anastomotic stricture who had undergone RYGB.
