Liver transplantation in a case of steatohepatitis and subacute hepatic failure after biliopancreatic diversion for morbid obesity.

BACKGROUND: Biliopancreatic diversion (BPD) was designed to avoid the serious complications of jejunoileal bypass (steatohepatitis and hepatic failure). Although this is today considered a safe and effective procedure, a few reports of patients who developed steatohepatitis and subsequently died in hepatic failure exist. METHODS: We report a morbidity obese patient who developed subacute hepatitis resulting in hepatic failure 1 year after BPD. RESULTS: Because of irreversible liver failure the decision to perform a liver transplantation was made. The patient underwent emergency liver transplant and lengthening of the common limb. The course of liver transplantation and the patient's recovery were uneventful. CONCLUSION: Severe liver disease may rarely follow BPD. Liver transplantation and lengthening of the common bowel may be performed to treat these patients.

"No punch" technique of laparoscopic vertical banded gastroplasty for morbid obesity.

BACKGROUND: This report describes the technical details and an initial evaluation of laparoscopic vertical gastroplasty modified for morbid obesity. After a surgical experience in 150 patients with open vertical banded gastroplasty (Mason's procedure), it was decided to perform a modified banded vertical gastroplasty. MATERIALS AND METHODS: Six patients were treated by this laparoscopic approach in 1997-1998. All patients were women with a mean age of 28 years (range 20-46). The mean body weight was 128 kg (range 105-146), and the mean BMI was 42.7 kg/m2 (range 35.6-53.0). Four or five 10- or 12-mm trocars were used. For all the dissection we used atraumatic ultracision (harmonic scalpel). In this procedure the technique of laparoscopic gastroplasty is performed without a circular gastric window. During the operation, 3 omental openings were made and the vertical staple-line was constructed by using a 30-mm 3-row linear stapler twice, establishing the gastric pouch. The outflow stoma was reinforced by a Gore-Tex band and calibrated to have an internal diameter of 10-15 mm. The band was sutured to itself. RESULTS: There were no deaths or complications. Operating time was 200 min (150-240). The nasogastric tube was removed at 1-2 days. The postoperative course was characterized by normal respiratory function and minimal pain in all cases. Patients were discharged 5-6 days after operation. CONCLUSIONS: Our technique excluded the circular gastric window (i.e., "no-punch") technique in the development of an effective and simple laparoscopic procedure to treat morbid obesity.

Application of the POSSUM system in bariatric surgery.

BACKGROUND: The POSSUM system has been devised for physiologic and operative scoring. The scoring system produced assessment for morbidity and mortality rates, which did not significantly differ from observed rates. The authors have applied this system to bariatric surgery. PATIENTS AND METHODS: 20 patients were scored by the POSSUM system. All underwent elective bariatric surgery during 1997. All patients were scored at the time of surgery with the physiologic score (FIS) and at discharge with the operative severity score (IQ). The FIS score included age; cardiac signs; chest radiograph; respiratory history; blood pressure; pulse; Glasgow coma score; determinations of hemoglobin, leukocyte, urea, sodium, and potassium levels; and electrocardiogram. The IQ score included multiple procedures, total blood loss, peritoneal soiling, presence of malignancy, and mode of surgery. RESULTS: The mean POSSUM score was 23.9. The mean FIS was 13.95 (12-22), and the mean IQ was 9.4 (7-16). The distribution of patients was performed for BMI. The group with BMI 35-45 (n = 4 patients) had a mean POSSUM score of 22.75, a mean FIS of 13.75, and a mean IQ of 9.0. The group with BMI >45 (n = 16 patients) had a mean POSSUM score of 24.18, a mean FIS of 14.62, and a mean IQ of 9.5. The morbidities were gastric fistula with peritonitis and deep venous thrombosis. The two complications had similar POSSUM scores with different BMIs. No mortality was observed. CONCLUSIONS: According to this experience, the POSSUM scoring system appears to provide an indicator of minor risk of morbidity and mortality in bariatric surgery with vertical banded gastroplasty.

Technical alternatives in laparoscopic distal gastric bypass for morbid obesity in a porcine model.

BACKGROUND: Laparoscopic gastric bypass and vertical banded gastroplasty are two procedures used in the treatment of morbid obesity. The authors describe alternative techniques of laparoscopic distal gastric bypass as a modification of the Scopinaro procedure, which were used experimentally in a porcine model. METHODS: Five pigs were used. The laparoscopic procedure was performed with the pigs under general anesthesia after pneumoperitoneum had been achieved. Five or six trocars were used. One port was converted from 12 to 33 mm, and all the other ports were 10-11 mm. The initial surgical technique was similar to that used by others for laparoscopic gastrectomy, except that atraumatic ultracision was used for all the dissection. The stomach was stapled with a linear cutter stapler (Endopath, 31 mm) to create a 50-ml pouch. The ileum was divided with a linear cutter-stapler (Endopath, 31 mm) or ultracision cautery. A long length of ileum was positioned between the stomach pouch and the jejunoileostomy. Only 50-70 cm of terminal ileum was preserved as a common channel. In three animals, the circular stapler (ILS, 21 mm) was used to produce an end-to-side anastomosis. In one animal, two purse-string sutures were handsewn in the ileum and jejunum stumps, and in another two animals, two endoloops were used for the anvil. In two animals, the linear stapler was used to form a side-to-side pouch stomach-ileum and jejunoileostomy anastomosis. In other animals, the two types of anastomosis have been combined. All animals were killed after surgery so that the anastomoses could be evaluated for size and integrity. RESULTS: In all animals, with the circular and linear stapler, both 21 and 13-15 mm anastomoses were intact. CONCLUSION: Distal gastric bypass is feasible laparoscopically, with intact anastomoses.
