Measurement of Functional Pouch Volume following the Gastric Bypass Procedure

Little is known about the effects of gastric bypass on the absorption of prescription medications in the post-operative state. This poses a considerable clinical dilemma especially that the prevalence of morbid obesity continues to escalate in the United States of America, and as a result the number of gastric bypass procedures performed each year has similarly increased dramatically. The author presented a case of a 45-year-old male with refractory hypertension, secondary to mechanical complications after a Roux-en-Y gastric bypass procedure due to anatomical alteration contributing to pill retention and change in medications' pharmacokinetics. Investigations for secondary causes of hypertension were made, patient’s blood pressure had become exceedingly difficult to control after his Roux-en-Y gastric bypass procedure and had only been controlled with IV medications. Further investigations confirmed the diagnosis of a mechanical gastrointestinal complication.

Gastric Bypass Procedure

When achalasia is unrecognised during the preoperative phase in patients who have undergone bariatric procedures, a late Heller oesophagomyotomy may be used as the treatment modality to prevent the development of megaoesophagus. We present the case of a 66-year-old man with achalasia 3 years after a Roux-en-Y gastric bypass procedure.

It is alleged that obesity is a risk factor in the occurrence of thrombophlebitis. It is the purpose of this investigation to study that inter-relationship.One hundred consecutive patients (21 male, 79 female) with an average age of 34 years were the subjects for this study. All patients were candidates for surgical intervention (gastric bypass procedure) because of obesity with minimum of 100 lbs over predicted weight. The mean weight was 279.2 lbs with a range of 191 - 500 lbs. The mean body mass index was 48 (weight kg/ (height cm)2). The incidence of deep vein thrombophlebitis by history was 3/100. The history of documented thromboembolism was zero.The incidence of post-operative clinical deep vein thrombophlebitis was zero. The incidence of postoperative thromboembolism was 3/100 (3.0%). None of these patients had a history of deep vein thrombophlebitis. The diagnosis of thromboembolism was confirmed by ventilation-perfusion scan. The mortality rate secondary to thromboembolism was 1/100 (1.0%).Obesity is not a risk factor in the occurrence of postoperative deep vein thrombophlebitis and thromboembolism. The various prophylactic medications and therapies for this group of patients may be an inappropriate risk, an undue cost and un-necessary discomfort.
