Transabdominal approach in the surgical management of Morgagni hernia.

PURPOSE: Morgagni hernias are uncommon diaphragmatic hernias that are generally asymptomatic, and so far only limited data have been reported. The objective of this retrospective study was to evaluate the outcome of patients presenting with a complicated Morgagni hernia and who undergo a transabdominal repair. METHODS: Between September 1999 and October 2005, 11 patients with Morgagni hernia were operated on in our department. Eight of them had acute presentations because of a complicated Morgagni hernia. The patient demographics, presenting symptoms, operative approach, and complications were collected. The postoperative course was evaluated for morbidity and mortality. RESULTS: The patients' ages ranged from 42 to 85 years (mean 69.4). Two (18.2%) patients were male and nine (81.8%) patients were female. Chest roentgenograms, computed tomography, and contrast meal studies were used as diagnostic utilities. A transabdominal approach was used for all patients. One patient died due to pulmonary failure. The mean follow-up was 2.8 years. There was no recurrence or symptoms regarding the operation in the remaining patients. CONCLUSION: We recommend the transabdominal approach in patients with Morgagni hernia as it makes it easy to reduce the hernia contents and repair of the hernia sac. Moreover, when complicated with strangulation, incarceration or perforation, a surgical repair through a transabdominal approach is mandatory.

Resveratrol, a red wine constituent polyphenol, protects gastric tissue against the oxidative stress in cholestatic rats.

This experimental study was designed to determine the effects of resveratrol on the level of malondialdehyde (MDA), reduced glutathione (GSH), and nitric oxide (NO) in gastric tissue after bile duct ligation (BDL). Swiss albino rats were divided into three groups: Group 1, sham (n = 7); Group 2, BDL (BDL only group; n = 7); and Group 3, BDL plus resveratrol (n = 7). Animals in the resveratrol group were treated with 10 mg/kg resveratrol (i.p.) once a day throughout 28 days. In the resveratrol group, levels of MDA and NO in gastric tissue were significantly lower than in the BDL-only group (P < 0.001). The level of GSH in the resveratrol group was significantly higher than in the BDL-only group (P < 0.001). The present study demonstrates that intraperitoneal administration of resveratrol maintains antioxidant defenses and reduces oxidative gastric damage. This effect of resveratrol may be useful to preserve gastric tissue under oxidative stress due to cholestasis.

Distribution of hydatid cysts into the liver with reference to cystobiliary communications and cavity-related complications.

BACKGROUND: This study was designed to test a hypothesis that intrahepatic hydatid cyst location can effect the incidence of cystobiliary communications and the cavity-related complications. METHODS: A total of 121 cysts treated by conservative surgical methods in 113 patients were evaluated prospectively. Cysts were grouped as near to the liver hilum (segment I, III, IVb, V, and VI) and far from the hilum (segment II, IVa, VII, and VIII). RESULTS: There were 58 (48%) hilar and 63 (52%) peripheral cysts. We found more cystobiliary communications (48% versus 27%, P = 0.015), more biliary leakage (36% versus 10%, P <0.001), and more biliary fistula (12% versus 3%, P = 0.080) in the cysts near to the hilum than far from the hilum. Postoperative hospital stay was longer in the cysts near to the hilum (12.3 +/- 3.1 days) than the cysts far from the hilum (7.7 +/- 2.7 days, P = 0.022). CONCLUSIONS: The location of the hydatid cyst near to the liver hilum is a risk factor for the cystobiliary communications and the cavity related complications.

Elimination of mucosectomy during restorative proctocolectomy in patients with ulcerative colitis may provide better results in low-volume centers.

BACKGROUND: To compare the outcomes of hand-sewn and double-stapling techniques among ulcerative colitis patients undergoing restorative proctocolectomy at a center that has limited experience with restorative proctocolectomy. METHODS: Forty-four patients with ulcerative colitis were divided into two groups according to the anastomosis techniques: hand sewing and double stapling. Postoperative early and late complications, postoperative hospital stay, and long-term functional results were compared. RESULTS: Pelvic sepsis (9% versus 36%, P = 0.03), operation time (median 240 minutes versus 270 minutes, P = 0.01), postoperative hospital stay (median 9 days versus 12 days, P = 0.04), and night incontinence (42% versus 80%, P = 0.07) were less common in the double-stapling group. CONCLUSIONS: We recommend the double-stapling technique to centers that do not have extensive experience with restorative proctocolectomy for ulcerative colitis. This technique provides a good postoperative course in most patients and provides satisfactory long-term results. The results of the double-stapling group were similar to the results of the high-volume centers.

Drainage of liver abscess via laparoscopic trocar with local anesthesia.

There are several methods for treatment of liver abscess. These include drainage by open surgery, laparoscopic surgery, or percutaneous catheterization. In this report a new therapeutic approach is presented. A 47-year-old man admitted to the hospital had an abscess 12 cm in diameter, originating from the left liver lobe. After the patient's permission was obtained, a laparoscopic trocar was inserted into the abscess with the patient under local anesthesia in the operating room. A 28-French chest tube catheter was introduced through the trocar cannula, and approximately 1,000 mL of pus was drained. There were no complications, and the patient was discharged on the same day. After computed tomography showed an obliterated abscess cavity, the drain was removed on postoperative day 7. The pus culture, performed on the day of surgery, was found to be positive for Escherichia coli, which was responsive to cefaclor. Oral antibiotic therapy was given for 1 month. At follow-up 2 months after surgery, the patient was asymptomatic. This report describes the first case of a liver abscess drained by a laparoscopic trocar with local anesthesia. This method can be the treatment of choice for some easily accessible liver abscesses.

Evacuation of hydatid liver cysts using laparoscopic trocar.

Several methods of reducing the likelihood of spilling live scolices during surgical removal of hydatid liver disease have been described. The aim was to determine the effectiveness and safety of laparoscopic trocar insertion for evacuation of hydatid liver cysts. This technique was used for 30 cysts in 19 patients who had surgery for hydatid liver disease. After establishing protection of the operative area, a laparoscopic trocar was inserted into the cyst at the most prominent point and the cyst was aspirated with large-bore suction and filled with a scolicidal agent. The technique was not attempted in two small cysts (<6 cm) located near the major blood vessels or in a single intraparenchymal cyst. Insertion of the trocar was successful in all remaining cysts, and there were no complications during the insertion or the evacuation. Successful evacuation (excellent and good outcomes) in unilocular, multilocular, and degenerated cysts were 100%, 84%, and 57%, respectively (p = 0.144), with a total success rate of 82%. Although successful evacuation was achieved in both anterior (92%) and posterior-superior located cysts (73%) (p = 0.203), excellent outcomes were higher for the anterior cysts (73%) than for the posterior-superior cysts (13%) (p = 0.005). Successful evacuation outcomes for the large (> 10 cm), middle-sized (6 to 10 cm), and small cysts (<6 cm) were 100%, 79%, and 67%, respectively (p = 0.591). The patients have been followed for a mean of 11 months (range 3 to 24 months), and no recurrence has been recorded. Insertion and evacuation of the hydatid liver cysts with a laparoscopic trocar is a safe and effective procedure, and its limitations are minimal.

Importance of cyst content in hydatid liver surgery.

HYPOTHESIS: Cyst content in hydatid liver surgery is a determinant of postoperative cavity-related complications. DESIGN: Cohort analytic study. SETTING: Referral public hospital. PATIENTS: Sixty-seven patients who had conservative surgery for hydatid liver disease were analyzed prospectively. Cysts were grouped as to the contents. Cysts containing bile and/or pus were considered complicated, whereas others were uncomplicated. After partial cystectomy, cavities were managed with external drainage, omentopexy, or introflexion, determined by the choice of the surgeons. MAIN OUTCOME MEASURES: Outcomes were measured by postoperative cavity-related complications, such as biliary leakage (leakage for 10 days or less), biliary fistula (leakage for more than 10 days), cavity infections, and postoperative hospitalization. RESULTS: Patient and cyst characteristics were comparable among the groups. External drainage technique had slightly more frequent cavity-related complications than omentopexy or introflexion (1.5-fold to 2-fold difference). More importantly, complications were significantly more frequent in the complicated cysts than in the uncomplicated cysts (7-fold to 30-fold difference). Mean postoperative hospitalization time for uncomplicated cysts was 6.5 days, and it was similar whether they were treated by external drainage, omentopexy, or introflexion (7.0, 6.2, and 5.8 days, respectively). Mean postoperative hospitalization time for complicated cysts was longer than for uncomplicated cysts (17.5 days; P =.008). CONCLUSIONS: Uncomplicated cysts have lower complication rates and short hospital stay with each cavity management technique. Complicated cysts have higher complication rates and longer hospital stay regardless of the management technique. Therefore, complicated and uncomplicated cysts should be considered different forms of the disease and evaluated differently.

An attempt to decrease ammonia levels after portacaval anastomosis in dogs: hepatic periarterial neurectomy.

Hepatic encephalopathy and elevated serum ammonia levels occur commonly after portacaval shunt and are hypothesized to be, in part, due to decreased hepatic blood flow. Prior work has demonstrated increased blood flow to the liver following hepatic periarterial neurectomy. In this experimental study, we investigated the functional, hemodynamic, and histopathological changes in the liver and kidney occurring after the addition of hepatic periarterial neurectomy to side-to-side portacaval shunt in dogs. It is our hypothesis that the addition of hepatic periarterial neurectomy to portacaval shunt will decrease postshunt ammonia levels. Side-to-side portacaval shunt was performed in 12 dogs (group I). Hepatic periarterial neurectomy was added to portacaval shunt in 9 dogs (group II). Serum levels of ammonia, urea, creatinine, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, albumin, and bilirubin together with hepatic blood flow were determined in both groups preoperatively and on postoperative day 21. The pre- and postoperative histopathologic changes of the liver and kidney were evaluated. There was significantly less postoperative elevation of serum ammonia and aspartate aminotransferase when hepatic periarterial neurectomy was added to the portacaval shunt procedure. Hemodynamic studies of hepatic artery and hepatic tissue indicated better blood flow in group II. The histopathologic evaluation of group II showed expansion of sinusoids, portal vessels, and portal areas and increased portal fibrosis as compared to group I. The results of this experimental study show that adding hepatic periarterial neurectomy to the portacaval shunt procedure improves postoperative serum levels of ammonia and aspartate aminotransferase and hepatic artery and tissue blood flow.

Liver volume measurement by spiral CT: an in vitro study.

Liver volume measurement has many clinical and research uses. The purpose of the present study is to evaluate experimentally the accuracy and reproducibility of spiral computed tomography (CT) in measuring liver volume. To determine the accuracy of spiral CT system, nine fresh (non-formalin-fixed) sheep livers were scanned in vitro. The collimation was 7 mm. The CT sections were stored on floppy disks and the images were transferred to the workstation that contained a software for volume measurement. The mean volume is 912+/-497 ml and the actual reference volume is 921+/-527 ml. The correlation between the CT system and actual reference measurement of sheep liver volumes was very strong. The correlation coefficient r was.998 (P<.001) on 7-mm sections. The mean difference between liver volume measurements was 4.95+/-3.23%. As a result, CT scan could be used as a reference noninvasive method for liver volume measurement in clinics.

Biliary complications after hydatid liver surgery: incidence and risk factors.

The aims of this study were to determine the incidence and risk factors of biliary leakage and biliary fistulae after hydatid liver surgery and to suggest preventive precautions. From January 1999 to June 2000, 70 cysts were examined from 54 patients who were operated on for hydatid liver disease. Age, sex, primary or recurrent disease, liver function tests, number, location, content, radiological type, and diameter and cavity management techniques were examined with univariate and multivariate analyses for biliary complications. Biliary leakage occurred in 14 cysts (26%) from the patients. Purulent and/or bilious cyst content (61.9% vs. 2.0%; P = 0.022), male gender (40.9% vs. 10.4%; P = 0.038), and pre-operative raised alkaline phosphatase and gamma glutamyl transferase levels (34.6% vs. 11.4%; P = 0.047) were found as independent risk factors for post-operative biliary leakage. Nine instances of biliary leakage (16.7%) closed spontaneously within seven days. The remaining five instances of biliary leakage (9.3%) persisted for more than 10 days and were accepted as biliary fistulae. Stepwise logistic regression identified cyst content was the only risk factor for biliary fistulae (19% vs. 2%; P = 0.036). Described risk factors for post-operative biliary complications after hydatid liver surgery may be the guidelines for additional pre-operative or intra-operative radiological interventions of the biliary tract and for preventive procedures such as surgical biliary drainage.

Nasogastric decompression after total gastrectomy.

BACKGROUND/AIMS: Although it is clearly known that there is no need of routine nasogastric decompression after some abdominal operations, we still do not know whether it is necessary for esophageal anastomosis. Traditionally, nasogastric decompression is mandatory after total gastrectomy complemented with esophagojejunostomy. METHODOLOGY: Consecutive 66 patients with gastric cancer who underwent total gastrectomy and esophagojejunostomy were prospectively evaluated. Patients were divided into two groups, those with nasogastric decompression and those without decompression. RESULTS: Postoperative complications were similar among the groups. Vomiting, distention, belching, hiccupping, dysphagia complaints were similar among the groups, but sore throat (100% vs. 22%, p<0.001), nausea (32% vs. 13%, p=0.054), fever (35% vs. 16%, p=0.068) and pulmonary complications (26% vs. 9%. p=0.072) were much more in the nasogastric decompression than the no-tube group. Starting oral feeding and postoperative hospital stay were similar in both groups. CONCLUSIONS: Omission of nasogastric decompression after elective total gastrectomy complemented with esophagojejunostomy did not increase postoperative complications, on the contrary it decreased postoperative fever and pulmonary problems, and improved patient comfort by decreasing sore throat and nausea. Therefore, we do not recommend the routine use of nasogastric tubes after total gastrectomy complemented with esophagojejunostomy.
