Single trocar laparoscopically assisted placement of central nervous system-peritoneal shunts.

BACKGROUND: Lumbar peritoneal and ventriculoperitoneal shunts are widely used for the treatment of hydrocephalus. In the past, the abdominal portion of these procedures required laparotomy. With the advent of minimally invasive techniques, laparoscopically assisted placement of the distal catheter has been tried. MATERIALS AND METHODS: We performed 10 shunt procedures (3 lumbar peritoneal, 6 ventriculoperitoneal, and 1 meningomyelocele-peritoneal) in 10 patients (mean age 56; age range, 30-78 years). Four patients had undergone previous open shunt placement that failed. The abdominal portion of the procedure was performed using a 5-mm trocar and a 10Fr introducer for camera and catheter insertion. In 3 cases, an additional 5-mm port was necessary for lysis of adhesions. These access punctures did not require fascial closure and caused minimal pain and limitation. RESULTS: No intra- or postoperative complications were encountered in this small patient group. At a median follow-up of 50 months (range, 3-56 months) all patients had functioning shunts. CONCLUSION: Single trocar laparoscopically assisted placement of central nervous system-peritoneal shunts is safe and simple, and should be considered the procedure of choice. This technique is also suitable for repositioning migrated catheters and other catheter-tip manipulations.

Superior mesenteric artery syndrome after laparoscopic Roux-en-Y gastric bypass for morbid obesity.

Gastrointestinal obstructive complications after laparoscopic Roux-en-Y gastric bypass (LRYGBP) are not uncommon. Their usual causes are strictures, internal hernias and adhesions. Superior mesenteric artery (SMA) syndrome is a rare disorder caused by compression of the third portion of the duodenum by the SMA that can occur after rapid weight loss. This has been reported in patients with scoliosis, burns, immobilization in body casts, and idiopathic weight loss. SMA syndrome following bariatric surgery has not been reported. We present 3 cases of SMA syndrome after LRYGBP and extensive weight loss. Two patients underwent laparoscopic duodenojejunostomy and the third patient was treated with intravenous hyperalimentation. All three are symptom free at 4-18 months follow-up. The diagnosis of SMA syndrome should be considered in bariatric surgery patients with rapid weight loss who develop atypical, recurrent obstructive symptoms not attributable to other common causes.

The experience of one institution dealing with terror: the El Aqsa Intifada riots.

BACKGROUND: During a period of 13 months--1 October 2000 to 31 October 2001--586 terror assault casualties were treated in the trauma unit and emergency department of Hadassah University Hospital (Ein Kerem campus); 27% (n = 158) were hospitalized and the rest were discharged within 24 hours. OBJECTIVES: To analyze the special requirements of a large number of victims who received treatment during a short period. METHODS: Data were attained from the main admitting office and the trauma registry records. Factors analyzed included age, gender, mechanism of injury, anatomic site of injury, Injury Severity Score, and length of stay. RESULTS: Males comprised 81% of the hospitalized patients. The majority of the injuries (70%) were due to gunshot wounds and 31% of the hospitalized patients were severely injured (ISS > or = 16). Twelve patients died, yielding a mortality rate of 7.5%. CONCLUSION: The nature of the injuries was more complex and severe than trauma of other etiologies, as noted by the mean length of stay (10.2 vs. 7.2 days), mean intensive care unit stay (2.8 vs. 0.9 days), and mean operations per patient (0.7 vs. 0.5). The mean insurance cost for each hospitalized terror casualty was also higher than for other trauma etiologies (US$ 3,200 vs. 2,500).

Laparoscopic resection of gastric diverticulum presenting after Roux-en-Y gastric bypass.

Gastric diverticula are extremely rare and may be congenital or acquired. Postgastrectomy formation of gastric diverticula has been attributed to outpouching through the weakened wall of the stomach. When symptomatic, gastric diverticula may cause pain, nausea, dysphagia, and vomiting. Gastric diverticula may also be associated with ectopic mucosa, ulcers, and neoplastic changes. We report a case of gastric cardia diverticulum that became symptomatic after laparoscopic Roux-en-Y gastric bypass. The patient was successfully treated with laparoscopic resection.

Percutaneous computed tomography-guided gastric remnant access after laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: The bypassed portion of the stomach is difficult to access and evaluate after Roux-en-Y gastric bypass. Access to the excluded stomach may be needed for nutritional support or decompression owing to acute distension and obstruction. We report our experience with percutaneous, computed tomography (CT)-guided gastrostomy tube placement into the gastric remnant after laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: Of 569 consecutive LRYGB procedures performed, 9 patients underwent successful percutaneous, CT-guided gastrostomy placement. One additional patient was referred from another facility. We reviewed the indications, interval from surgery to the intervention, interval to removal, complications, and success or outcome of the procedure in our patient population. RESULTS: Ten patients underwent percutaneous, CT-guided gastric remnant gastrostomy tube placement. The indications included distended gastric remnant in 6, nutritional access in 4, and remnant drainage after leak in 1. Of the 10 patients, 2 had undergone previous gastric operations. The attempt at percutaneous gastrostomy was unsuccessful in 1 additional patient, who subsequently required laparoscopic gastrostomy (success rate 91%). CONCLUSION: In selected patients after LRYGB, CT-guided gastrostomy tube placement is safe and efficient. It may be used to manage complications of LRYGB, serve as a bridge to definitive surgery, or offer a convenient route for enteral nutritional support.

Late perforation of the jejuno-jejunal anastomosis after laparoscopic Roux-en-Y gastric bypass.

Roux-en-Y gastric bypass (RYGBP) is the most commonly performed operation for the treatment of morbid obesity in the USA. Complications related to the jejuno-jejunal (J-J) anastomosis include postoperative leak, staple-line bleeding and obstruction. We present 3 cases of perforation at the J-J anastomosis occurring more than 30 days after surgery. 3 morbidly obese patients underwent laparoscopic RYGBP. The side-to-side J-J anastomosis was created with a linear stapler, and the anastomotic defect was closed with a running absorbable suture. All 3 patients had uneventful recoveries, but presented 7 to 8 weeks postoperatively with acute abdominal pain and peritoneal signs. Exploratory laparoscopy in these patients revealed a perforation at the J-J anastomosis. No apparent reason for the perforation was found in 2 patients. These perforations were repaired laparoscopically with absorbable suture. The third patient had an obstruction at the J-J anastomosis from an phytobezoar and required conversion to open technique due to limited pneumoperitoneum. All 3 patients recovered uneventfully. Late perforation of the J-J anastomosis is a very rare complication. Primary laparoscopic repair is a feasible and safe choice of treatment.
