RESUMO
The frequency and significance of right hepatic artery injury associated with bile duct injury after laparoscopic cholecystectomy is unknown. Many reports suggest that a concomitant arterial injury worsens the outcome and prognosis of the bile duct injury even after an initially successful biliary repair. The optimal management of this complicated injury is controversial. We report a surgical technique to repair the right hepatic artery injury in these cases. We believe this technique is useful for surgeons who opt to repair the arterial injury at the time of biliary reconstruction, especially if it is performed soon after the injury occurred, before permanent damage to the liver and biliary system is established. To the best of our knowledge, this technique was not reported in the literature previously.

OBJECTIVE: To evaluate the outcomes of a single surgeon's experience with laparoscopic Roux-en-Y gastric bypass (LRYGB) utilizing the triple stapling technique for creation of the jejunojejunostomy. METHODS: A retrospective review of patients who underwent LRYGB utilizing the triple stapling technique for creation of the jejunojejunostomy (JJ) between 10/01 and 12/04 was performed. RESULTS: LRYGB was performed in 435 consecutive patients. The mean age was 41 years (range, 14 to 68), and 82% were female. Mean initial body mass index was 50 (range, 35 to 91). One conversion to open (0.2%) was necessary. Mean operating time was 144+/-26 minutes. Mean length of stay was 2.3+/-1.5 days. There were 3 leaks at the gastrojejunostomy anastomosis (0.7%). No leaks occurred at the JJ anastomosis. One patient underwent revision of the JJ (0.2%) secondary to obstruction of the JJ on upper gastrointestinal study. Intraluminal bleeding occurred in 21 patients (4.8%). Patients required blood transfusion of 2.2+/-1.1 units (range, 0 to 5), but none required surgical or endoscopic intervention. Mortality occurred in 2 patients (0.5%). Mean excess body weight loss was 72% at 1 year. CONCLUSION: Construction of the jejunojejunostomy utilizing the triple stapling technique is expeditious, safe, and associated with minimal complication.

OBJECTIVES: Approximately 80% of patients complain of various symptoms immediately after laparoscopic Nissen fundoplication. These symptoms typically are treated medically without an extensive evaluation to identify the cause. We reviewed our experience of laparoscopic Nissen fundoplication to determine the course of postoperative symptomatology in our patient population, and present a rational approach to this problem. METHODS: Over a 10-year period, 628 patients underwent primary laparoscopic Nissen fundoplication for gastroesophageal reflux disease; patients were evaluated with a standard set of questions for postoperative gastrointestinal complaints. Three- and 6-month follow-up data were compared by using the chi square test. RESULTS: One-year follow-up data were available for 615 patients (98%). All of these patients had symptoms during the first 3 postoperative months. Early satiety (88%), bloating/flatulence (64%), and dysphagia (34%) were the most common; however, 94% of patients had resolution of their symptoms by the 1-year follow-up visit, and most had resolved after 3 months. Patients with persistent reflux or dysphagia after 3 months typically had an anatomic failure of the operation. CONCLUSIONS: Most patients who have undergone laparoscopic Nissen fundoplication for gastroesophageal reflux disease will have gastrointestinal complaints during the initial 3 postoperative months. Nearly all of these patients will have resolved their symptomatology after 3 months. Those with persistent symptoms after 3 months warrant evaluation for operative failure.

The risk factors for nonalcoholic fatty liver disease in patients undergoing bariatric surgery are under study. We wanted to determine the correlation between nonalcoholic fatty liver disease and patient factors such as obesity and liver function tests. A retrospective analysis was performed on 177 nonalcoholic morbidly obese patients who underwent laparoscopic Roux-en-Y gastric bypass with liver biopsy, to identify risk factors for nonalcoholic fatty liver disease. The histologic grade of liver disease was compared with preoperative body mass index, age, and liver function tests. Simple steatosis and steatohepatitis were present in 90% and 42% of patients, respectively. Elevated transaminase levels were an independent risk for liver disease. Body mass index and liver disease were not correlated with univariate analysis. Regression analysis performed on age, body mass index, and liver disease demonstrated that the risk for liver disease increased with body mass index in the younger (<35 years old) age group and decreased with body mass index in the older (>45 years old) age group. There was a high incidence of steatosis and steatohepatitis in these nonalcoholic bariatric patients, and elevated transaminase level was indicative of disease. Body mass index was a positive risk factor for liver disease in younger patients but a negative risk factor in the older patients.

Minimally invasive esophagomyotomy for achalasia has become the preferred surgical treatment; the employment of a concomitant fundoplication with the myotomy is controversial. Here we report a retrospective analysis of 53 patients with achalasia treated with laparoscopic Heller myotomy; fundoplication was used in all patients except one, and 48 of the fundoplications were complete (floppy Nissen). There were no deaths or reoperations, and minor complications occurred in three patients. Good-to-excellent long-term results were obtained in 92% of the subjects (median follow-up 3 years). Two cases (4%) of persistent postoperative dysphagia were documented, one of which was treated with dilatation. Postoperative reflux occurred in five patients, four of whom did not receive a complete fundoplication; these patients were well controlled with medical therapy. We suggest that esophageal achalasia may be successfully treated with laparoscopic Heller myotomy and floppy Nissen fundoplication with an acceptable rate of postoperative dysphagia.

BACKGROUND: High-grade dysplasia of the esophageal mucosa has been shown to be a precursor to adenocarcinoma. In addition to esophagectomy, multiple ablative endoscopic techniques have evolved for the management of this condition. As a surgical alternative to esophagectomy, we describe for the first time a new option in the treatment of high-grade dysplasia. MATERIALS AND METHODS: Two patients with a history of gastroesophageal reflux disease (GERD) underwent upper gastrointestinal endoscopy which demonstrated high-grade dysplasia of the distal esophagus. The first patient had a short segment (0.5-1.0 cm), and the second patient had a longer (2 cm) segment of dysplasia. The patient is placed in the modified lithotomy position. Five trocars are placed as if to perform a fundoplication. A complete circumferential mobilization of the esophagus is performed. The short gastric vessels are divided with the harmonic scalpel, to free up the fundus of the stomach. An anterior horizontal gastrotomy is performed three to four centimeters below the gastroesophageal junction. A solution of epinephrine and normal saline (1:100,000) is injected into the mucosa at the Z-line and, utilizing specially designed hook electrocautery, the mucosa is incised circumferentially around a lighted bougie. Using blunt dissection the mucosa is undermined, elevated, and excised in four quadrants. Three centimeters of the distal esophageal mucosa are resected. The gastrotomy is then closed using a linear stapler, and a 360 degrees fundoplication is performed around a 50 Fr bougie. RESULTS: High-grade dysplasia was identified in the specimens from both patients; however, neither patient was found to have carcinoma in situ or invasive esophageal cancer. Our first patient has been followed for twenty months, the second for ten months. Both patients underwent routine upper gastrointestinal endoscopy for surveillance of the healing process. At eight months, the mucosa of the first patient showed complete regeneration of squamous epithelium. Our most recent patient appears to be progressing without complications and has also demonstrated normal squamous epithelium at ten months postoperatively, without changes of Barrett's epithelium. CONCLUSION: The technique of laparoscopic transgastric esophageal mucosal resection is feasible and may be proven to be an alternative to esophagectomy for the management of high-grade dysplasia.
