Vertical gastroplasty as a treatment method in morbid obesity

Pelvic floor rehabilitation is used to treat stress urinary incontinence, urge, and fecal incontinence as well as other pelvic floor musculature disorders. When treating patients, it is important to thoroughly assess the pelvic floor. In addition to evaluating the urinary system, sexual and bowel functions must also be considered. Treatment plans should be devised on an individual basis according to the evaluation findings. Rehabilitation goals should be established. The patient must understand the function of her urinary system and the role she must play in its control. Muscle retraining is achieved through a personalized exercise program. This program may be augmented by manual techniques, biofeedback or electrical stimulation. While the Agency for Health Care Policy and Research (AHCPR) does endorse the use of behavioral modalities in treating urinary incontinence, the use of bladder retraining and pelvic floor rehabilitation is not always recommended when indicated, nor accessible for all patients who require it. More research is needed, in addition to ongoing public and professional education on behavioral interventions in order to underline the advantages of this form of treatment for incontinence.     

Intestinal bypass surgery for morbid obesity. Long-term results

Since 1962, jejunoileal bypass has been performed on 59 male and 171 female subjects, aged 18 to 55 years; these patients were followed clinically. Postoperative weight loss at two years averaged 37% in men and 35% in women. Hypokalemia (23%), hypocalcemia (22%), hypoalbuminemia (9%), metabolic acidosis (14%), elevated liver enzyme values (41%), and hyperbilirubinemia (6%), were the most commonly encountered blood chemical alterations. Complications were arthritis syndrome (men, 8%; women, 19%). urinary calculi (men, 24%; women, 10%), cholelithiasis (men, 10%; women, 9%), liver impairment (men, 2%; women, 6%), and major emotional upset (men, 8%; women, 9%). Forty-nine percent of the men and 51% of the women required rehospitalization for management of complications, surgery for hernia, anorectal disorders, nutritional support, and metabolic study. There were 19 bypass-related deaths (8%), including 10 due to liver failure.     

Lipid composition of bile in morbid obesity before and after jejunoileal bypass surgery

Bile cholesterol, phospholipids, total bile acids, individual bile acids, and fatty acid compositions of bile neutral lipids and phospholipids were analyzed before, at one month and at six months following jejunoileal bypass surgery in a series of morbidly obese patients. Preoperative mole percentages of cholesterol and lithogenic indices were high, indicating that biles were supersaturated with cholesterol and outside the micellar solubility zone when plotted on triangular coordinates. At the one month post-operative period percentages of cholesterol and lithogenic indices were significantly increased as compared to the pre-operative state. At six months post-operatively these values had decreased to approximately the pre-operative levels. No changes were observed in percentages of lithocholic acid, but deoxycholic acid decreased to markedly low levels at one month and remained low at the six month post-operative interval. Relative proportions of cholic acid increased, and the ratio of cholic to chenodeoxycholic acid was significantly increased at both post-operative intervals. No significant changes were noted in bile neutral lipid or phospholipid fatty acid composition, indicating that no depletion of essential fatty acids had occurred.     

Overview of operations for morbid obesity

High-dose busulphan is an important component of many BMT conditioning regimens. High-dose busulphan therapy is associated with an increased risk of acute toxicity such as CNS toxicity and veno-occlusive disease (VOD). The toxicity was reported to correlate with a high AUC (area under the curve) during therapy. An intravenous form of busulphan would overcome the problems caused by inter-individual variability and bioavailability of busulphan and most probably minimize the problems with dose adjustment during therapy. The liposomal form of busulphan is an attractive alternative for intravenous administration of busulphan. In the present study, we compared the myeloablative effect of liposomal busulphan (LB) with that of the oral administration form and busulphan dissolved in organic solvent (Bus/DMSO) in mice. The pharmacokinetics of LB and Bus/DMSO were described by one compartment model while the oral data were fitted to one compartment model with first order absorption. The bioavailability of LB was 0.86+/-0.02 compared to that obtained after the oral administration (0.40-0.74). Myelosuppression was determined using the colony-forming unit granulocyte-macrophage assay (CFU-GM) on days 1, 3, 6 and 9 after the conditioning regimen. LB resulted in significant myelosuppression from day 1 to day 9. The decrease in CFU-GM after conditioning regimen with LB was not significantly different from that observed after oral busulphan. Moreover, the administration of liposomes only to the mice did not affect the bone marrow. No side-effects of the liposomal formulation were observed. We suggest that the novel form of busulphan is a promising drug for clinical use.     

Clavicular osteomyelitis as a complication of head and neck surgery

To investigate the development of airway hyperresponsiveness in infantile guinea pigs, animals (10 days old) were immunized twice and challenged by inhalation of 1% ovalbumin for 10 min with 7 days intervals. Similar to adult guinea pigs, infantile ones developed an increased airway responsiveness to acetylcholine 24 hr after antigen challenge. There was a marked increase in the number of total leukocytes, eosinophils and lymphocytes in bronchoalveolar lavage fluid (BALF). Suplatast tosilate (suplatast) and pemirolast potassium (pemirolast) given orally throughout the experiments suppressed the development of airway hyperresponsiveness in infantile animals. They showed similar potency in the suppression of eosinophil accumulation in BALF and lung tissue, while suplatast inhibited lymphocyte accumulation stronger than pemirolast. Collectively, the present model of airway hyperresponsiveness in infantile guinea pigs may be useful in predicting the efficacy of antiallergic agents in the treatment of asthmatic children.     

Pregnancy following gastric bypass for morbid obesity

BACKGROUND: Women who suffer from morbid obesity are often infertile. If these women are able to become pregnant, they are considered high risk because of the hypertension, diabetes and other associated risk factors. Following the pregnancy is difficult due to limitations of the physical examinations. More costly ultrasound examinations are needed at a higher frequency. Bariatric surgery reduces the woman's weight and the incidence of obesity related co-morbidities. The number of pregnancies and rate of complications during those pregnancies in our post-bariatirc surgical patients were evaluated. METHOD: Our group has been doing bariatric surgery since the early 1980s. We have over 2000 active patients on our current newsletter mailing list. The patients also have a series of networks through support groups. The patients are informed to contact us when they become pregnant so we may assist the obstetrician with their care. Through these various means, we have been able to identify 41 women in our patient population who have become pregnant. Using personal interview, questionnaire, and review of perinatal records, pregnancy-related risks and complications were studied. RESULTS: With over a 95% follow-up rate on the patients identified as having been pregnant following surgery, we found less risk of gestational diabetes, macrosomia, and cesarean section than associated with obesity. There were no patients with clinically significant anemia. CONCLUSION: Since the patients had an operation that restricts their food intake, some basic precautions should be taken when they become pregnant. With this in mind, our patients have done well with their pregnancies. The post-surgical group had fewer pregnancy-related complications than did an internally controlled group that were morbidly obese during their previous pregnancies.     

Jejunoileal bypass for the treatment of morbid obesity

With a reported mortality rate of less than 0.5%, and an immediate morbidity of 2% to 4%, jejunoileal bypass may result in a more significant weight loss than can be achieved with gastric bypass. Jejunoileal bypass cannot be outeaten, whereas gastric bypass can. Careful attention to preoperative, intraoperative and postoperative procedures will protect most jejunoileal bypass patients from both the side effects and complications of this surgical technique, allowing the morbidly obese to achieve the maximum benefit from intestinal bypass with fewer adverse results.     

Pneumocephalus as a complication of posterior fossa surgery in the sitting position

A case of pneumocephalus complicating posterior fossa surgery in the sitting position is presented. Rapid diagnosis was obtained by computerised tomography. This condition should be suspected whenever a patient demonstrates delayed recovery or neurological deficit after craniotomy and nitrous oxide anaesthesia. The literature on the subject is reviewed.     

Radiology of adjustable silicone gastric banding for morbid obesity

We reviewed the radiological findings in 45 morbidly obese patients (weight range 80-129 kg; mean 95.7 kg) after gastric restriction surgery with adjustable silicone gastric banding (ASBG) according to the Kuzmak technique. Radiographic studies of the stomach were performed before, and at 4 and 12 months after surgery; symptomatic patients underwent additional studies when needed. Patients were evaluated using both liquid barium and a solid opaque meal to assess post-operative gastric morphology as well as emptying time of the proximal gastric pouch. 27 patients had a normal clinical course. Variation of the calibre of the silicone band under radiographic guidance was required in 12 of these patients, based on dilatation of the proximal pouch, variation of the stomal calibre from operative values, or an emptying time longer than 30 min. All these problems disappeared after the adjustment manoeuvres. 18 patients had complications, of which five had stomal stenosis which could not be managed through simple deflation of the band; two had posterior bending and dilatation of the proximal pouch; four had gastritis and oesophagitis; six had infection of the inflatable reservoir; one had cranial displacement of the band, and two had migration of the band into the stomach. Removal of the gastric band was necessary in 11 cases, and removal of the reservoir alone had to be performed in three additional patients. Radiology plays an important role in evaluating complications after gastric restriction surgery. Knowing the variety of findings enables accurate treatment planning and follow-up of these patients.     

Gastroplasty for morbid obesity. Guidelines for post-operative management

Morbid obesity is a very difficult condition to treat. Any operation intended to help the patient Jose weight is no more than a beginning, and must be combined with rigorous postoperative care or it will surely fail.     

Therapeutic failures after gastric bypass operations for morbid obesity

BACKGROUND: Although gastric bypass is an effective treatment for morbid obesity, the postoperative results are unsatisfactory in 10% of all patients. Therapeutic failures after an operation performed with the sole purpose of reducing the risk of obesity-associated diseases have to be taken seriously. The goal of this study was to investigate the causes of these failures. METHOD: From 1979 to 1993, 165 gastric bypass operations (technique: Mason-Griffen) were performed. Long-term results were obtained in 60 patients after an average of 6.6 years (range 3-13). On follow-up all patients were examined and asked about their level of satisfaction with the weight loss achieved and changes in eating habits. RESULTS: In 6 patients the weight reduction was regarded as insufficient (BMI > 35 and reduction of BMI < 10). The causes of these failures were technical in 3 cases (gastric pouch to 0 large in 1, dilatation of gastrojejunostomy in 2). Three patients had a high calorie intake through an intact gastric bypass by snacking. Three patients regarded the operation as a failure although they had achieved significant weight loss, because they could no longer eat the usual amounts of food. CONCLUSION: Correct surgical technique and preoperative information on the changes in eating habits after a gastric bypass operation are the most important steps in preventing therapeutic failures.     

Gastric bypass for morbid obesity: results and complications

Seventy-five patients underwent a 90 percent distal gastric bypass for morbid obesity. The average weight was 121.4 kilogram, height 164 centimeters, and age 31.4 years in these 70 women and five men. There was a total of 20 surgical complications in the 75 patients, with wound infection being the most common. Sixteen chronic complications were noted and consisted of vomiting, diarrhea, reflux esophagitis, dysphagia, and vitamin deficiencies. None of the above complications were life-threatening or required dismantling of the bypass. Of 54 patients followed for 12 months or more after gastric bypass, there was a 24.5 percent average weight decrease at 6 months, and this progressed to 35.8 percent by 12 months. Fifty-two patients undergoing small bowel bypass previously at the same institution had a 25.4 percent weight reduction at 12 months. Of 54 patients, 83 percent followed for one or more years after gastric bypass have had an excellent or good clinical result, whereas only 42 percent of the 52 patients undergoing small bowel bypass have had an excellent or good clinical result with the same criteria. It is concluded that the Mason 90 percent distal gastric bypass is a suitable form of surgical treatment for the morbidity obese patient who cannot lose weight by dietary measures.     

The role of laparoscopy in the treatment of morbid obesity

The protective effect of ceftriaxone on isepamicin-induced nephrotoxicity was investigated. For 14 d, Wistar rats were administered either ceftriaxone 100 mg/kg intraperitoneally, isepamicin 300 mg/kg subcutaneously, or ceftriaxone isepamicin in combination. The animals given 300 mg/kg of isepamicin showed a significant increase in urine NAG (N-acetyl-beta-D-glucosaminidase) levels as compared with the control animals which received saline (p<0.01). However, the increase in NAG level was markedly less when isepamicin was administered in combination with ceftriaxone (p<0.01). Ceftriaxone alone had no effect on urine NAG activity. Serum creatinine levels were significantly higher in animals treated with isepamicin alone than in control animals (p<0.01) or animals receiving the isepamicin ceftriaxone combination (p<0.01). After 14 d of treatment, ceftriaxone had not accumulated in renal tissue, but it did reduce the renal intracortical accumulation of isepamicin (p<0.01). Histopathologically, ceftriaxone induced very few cellular alterations and considerably reduced the manifestation of typical signs of isepamicin nephrotoxicity. This investigation demonstrates that ceftriaxone protects animals against isepamicin-induced nephrotoxicity.
