BACKGROUND Multiple techniques have been introduced to obtain fascial closure for the open abdomen to minimize morbidity and cost of care. We hypothesized that a modification of the vacuum-assisted closure (VAC) technique that provides constant fascial tension and prevents abdominis rectis retraction would facilitate primary fascial closure and reduce morbidity. METHODS In all, 53 patients with severe abdominal sepsis were allocated randomly into 2 groups, and 30 patients were analyzed. In the VAC group, we included patients managed only with the VAC device, whereas the retentions sutured sequential fascial closure (RSSFC) group included patients to whom RSSFC was performed. RESULTS The abdomen was left open for 12 days (P = .0001) with 4.4 ± 1.35 changes per patient for the VAC group (P = .001) and 8 days with 2.87 ± 0.74 dressing changes per patient for the RSSFC group, respectively. Abdominal closure was possible in only 6 patients in the VAC group, whereas for the RSSFC group, abdominal closure was achieved in 14 patients (P = .005). Planned hernia was exclusively decided in patients in the VAC group (P = .001). The hospital stay was 17.53 ± 4.59 days for the VAC group and 11.93 ± 2.05 days for the RSSFC group (P = .0001). The median initial intra-abdominal pressure (IAP) was 12 mm Hg for the VAC group and 16 mm Hg for the RSSFC group (P < .0001). CONCLUSION We demonstrated the superiority of RSSFC compared with the single use of the VAC device. In our opinion, sequential fascial closure can immediately begin when abdominal sepsis is controlled.

For cardiothoracic surgeons prosthetic graft infection still represents a difficult diagnostic and treatment problem to manage. An aggressive surgical strategy involving removal and in situ replacement of all the prosthetic material combined with extensive removal of the surrounding mediastinal tissue remains technically challenging in any case. Mortality and morbidity rates following such a major and risky surgical procedure are high due to the nature of the aggressive surgical approach and multi-organ failure typically caused by sepsis. However, removal of the infected prosthetic graft in patients who had an operation to reconstruct the ascending aorta and/or the aortic arch is not always possible or necessary for selected patients according to current alternative treatment options. Rather than following the traditional surgical concept of aggressive graft replacement nowadays a more conservative surgical approach with in situ preservation and coverage of the prosthetic graft by vascular tissue flaps can result in a good outcome. In this article, we review the relevant literature on this specific topic, particularly in terms of graft-sparing surgery for infected ascending/arch prosthetic grafts with special emphasis on staged treatment and the use of omentum transposition.

Background: This prospective study determines the value of laparoscopic cholecystectomy (LC) in patients with cholelithiasis after bariatric surgery. Methods: Eighty-four consecutive patients who underwent bariatric surgery without concomitant cholecystectomy were studied. Patients were divided in two groups; group A including 50 patients (59.5%) without gallbladder disease, and group B included 34 patients (40.5%) with symptomatic cholelithiasis within 2 years postoperatively. Characteristics of both groups were compared and analyzed by the use of chi-square tests. Results: In all 34 patients in group B LC was attempted, and the procedure was successful in 28 (82.4%). LC was converted to open procedure in 6 patients (17.6%). Two patients with choledocholithiasic obstructive jaundice underwent endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy prior to laparoscopic management. The mean operative time was 75 ± 12 min, and the mean hospitalization was 2.8 ± 1.1 days. Conclusion: Morbidly obese patients undergoing bariatric surgery are at high risk for developing symptomatic cholelithiasis postoperatively, which usually takes the form of acute cholecystitis. LC is feasible, effective, and seems to be the procedure of choice despite the technical difficulties.

Abstract Endometriosis is the presence of endometrial glands and stroma outside the uterus. Spontaneous abdominal wall endometriosis (AWE) is any ectopic endometrium found superficial to the peritoneum without the presence of any previous scar. Rarely, endometriosis represents a disease of specific interest to the general surgeon, on account of its extrapelvic localisations. We describe a case with spontaneous AWE presenting as a painful mass with cyclic symptoms. A 28-year-old woman presented to the day-surgery division of our department, suffering from a painful mass in the left lower abdominal quadrant. A mobile mass of 5 χ 4 cm was identified. The initial diagnosis was lipoma and excision was planned. During the operation two masses were spotted, very close to one another, and were excised within healthy limits. Pathology revealed endometrial glands surrounded by a disintegrating mantle of endometrial stroma and fibrous scar tissue in which there was a scattering of leucocytes. The woman had no scars. She was discharged from hospital after 2 hours. Two years after the excision she is free of disease and no recurrence has been observed. Spontaneous AWE is rare, accounting for 20% of all AWEs. The triad ; mass, pain and cyclic symptomatology helps in the diagnosis, but unfortunately it is not present in all cases. Spontaneous endometriomas are usually diagnosed by pathology and the treatment of choice is surgical excision.

BACKGROUND Laryngeal complications occur in thyroidectomies as a result of several factors, but especially because of nerve damage. We compared intraoperative stimulation neuromonitoring (IONM) with intraoperative continuous electromyographic neuromonitoring (IEM) to evaluate their ability to identify postoperative laryngeal complications. METHODS This prospective clinical trial included 174 patients (348 nerves) who had both IONM and IEM. We recorded age, sex, pathology, vocal fold motility, and complications. RESULTS IONM identified 334 nerves, whereas IEM identified 348. Five patients had transient laryngeal complications, 2 bilateral, and 3 unilateral recurrent laryngeal nerve paresis. In addition, in 2 patients IEM showed placement of the tracheal tube balloon on the vocal folds, which led to correction. Sensitivity and specificity were 96.48% and 100% for IONM and 100% and 100% for IEM, respectively. IONM had a positive predictive value of 100% and a negative predictive value of 36.84%. The positive and negative predictive values of IEM were 100%. CONCLUSIONS Both techniques identify recurrent laryngeal nerve injuries; however, IEM seems to have an advantage concerning the nonsurgical laryngeal complications and may play a role in preventing morbidity.

IntroductionAmebiasis is a parasitic disease caused by Entamoeba histolytica. It most commonly results in asymptomatic colonization of the gastrointestinal tract, but some patients develop intestinal invasive or extra-intestinal diseases. Liver abscess is the most common extra-intestinal manifestation. The large number of clinical presentations of amebic liver abscess makes the diagnosis very challenging in non-endemic countries. Late diagnosis of the amebic abscess may lead to perforation and amebic peritonitis, resulting in high mortality rates.Case presentationThis report describes a 37-year-old white man, suffering from hepatitis B, with a gigantic amebic liver abscess presenting as an acute abdomen due to its rupture. Rapid deterioration of the patients condition and acute abdomen led to an emergency operation. A large volume of free fluid together with debris was found at the moment of entry into the peritoneal cavity because of a rupture of the hepatic abscess at the position of the segment VIII. Surgical drainage of the hepatic abscess was performed; two wide drains were placed in the remaining hepatic cavities and one on the right hemithorax. The patient was hospitalized in the ICU for 14 days and for another 14 days in our department. The diagnosis of amebic abscess was made by the pathologists who identified E. histolytica in the debris.ConclusionAcute abdomen due to a ruptured amebic liver abscess is extremely rare in western countries where the parasite is not endemic. Prompt diagnosis and treatment are fundamental to preserving the patients life since the mortality rates remain extremely high when untreated, even nowadays.

Introduction: Allopurinol acts protectively in the ischemia reperfusion injury of the small intestine. The aim of this experimental study is to define the ideal time of administration of allopurinol, in experimental models of ischemia/reperfusion. Materials and Methods: We used 46 rabbits that were divided into four groups. Group A was the control. In Group B allopurinol was administered 10 min before ischemia and in Group C 2 min before reperfusion. In Group D, allopurinol was administered before ischemia and before reperfusion in half doses. Blood samples were collected at three different moments: (t1) prior to ischemia, (t2) prior to reperfusion, and (t3) after the end of the reperfusion, in order to determine superoxide dismutase (SOD) and neopterin values. Specimens of the intestine were obtained for histological analysis and determination of malondialdehyde (MDA). Results: In Group A, mucosal lesions were more extensive compared to those of the other three groups. Similarly, MDA, SOD and neopterin values were significantly higher. On the contrary, Group D showed the mildest mucosal lesions, as well as the lowest MDA, SOD and neopterin values. Finally, the lesions and the above mentioned values were bigger in Group C than in Group D. Conclusions: The administration of allopurinol attenuates the production and damage effect of free oxygen radicals during ischemia reperfusion of the small intestine, thus protecting the intestinal mucosa. Its maximum beneficial action is achieved when administered both before ischemia and before reperfusion of the small intestine.
