Gastric leak is the most common cause of major morbidity and mortality after LSG. Routine tests to rule out leaks seem to be superfluous. Rather, selective utilization is recommended. Management options vary, depending mainly on patient disposition. An accepted algorithm for the diagnosis and treatment of gastric leak has yet to be proposed.
Despite a lack of a high level of evidence in its favour, LA has practically replaced OA in the management of small and medium-size benign functioning and non-functioning adrenal lesions, as it has proved to be as effective as OA with less associated morbidity. Although limited experience with large and malignant tumours shows some promise, present data are insufficient for clear conclusions to be drawn.
An appendiceal mass is the end result of a walled-off appendiceal perforation and represents a pathological spectrum ranging from phlegmon to abscess. Over the past decade, improved imaging and interventional radiological techniques have allowed a more accurate definition of pathology and thus a more specific and less invasive management than was previously possible. A management policy should be possible that allows over 80 per cent of patients presenting with an appendiceal mass to be safely spared an open operation.
The experience with laparoscopic pancreatic surgery (LPS) in general, and pancreatic islet cell tumors (ICTs) in particular, is still limited. Because insulinoma is the most prevalent tumor and is mostly benign, single, and curable with surgical excision, it comprises most of the cases. Our experience with 17 cases (10 insulinomas, 2 gastrinomas, 1 nesidioblastoma, 4 nonfunctioning tumors) and those recorded in the literature (93 cases) show that laparoscopic surgery for small, solitary benign islet cell tumors located in the body and tail is feasible and safe and can result in rapid postoperative recuperation and a complication rate comparable or lower than that achieved with open surgery. It duplicates the success rate seen with conventional surgery regarding intraoperative localization and cure of disease. The main morbidity continues to be the occurrence of a fistula (18%), most often after enucleation, but the clinical course is benign in most instances. Preoperative imaging studies are required for localization, and the combined use of biphasic helical computed tomography and endoscopic ultrasonography (US) seems to be cost-effective. The use of laparoscopic US is an integral part of the laparoscopic procedure, and the information achieved is valuable for both confirming localization and decision making concerning the most appropriate surgical procedure. In cases of distal pancreatectomy, splenic salvage, preferably with preservation of splenic vessels, is feasible albeit more demanding and can be achieved in most cases.
Resection yields superior results, yet the majority of surgeons ablate, probably because it is easier, requires a shorter operating time, leads to fewer cases of Horner's syndrome, and because resympathectomy eventually overcomes initial failure.
Primary palmar hyperhidrosis (HH) is a pathological condition of overperspiration caused by excessive secretion of the eccrine sweat glands, the etiology of which is unknown. This disorder affects a small but significant proportion of the young population all over the world. Neither systemic nor topical drugs have been found to satisfactorily alleviate the symptoms. Although the topical injection of botulinum has recently been reported to reduce the amount of local perspiration, long-term results are required before a definitive evaluation of this method can be made. Hypnosis, psychotherapy, and biofeedback have been beneficial in a limited-number of cases. While radiation achieves atrophy of the sweat glands, its detrimental effects prohibit its use. Iontophoresis has attained some satisfactory results but it has not been assessed long term. Percutaneous computed tomography-guided phenol sympathicolysis achieves excellent immediate results, but its long-term failure rate is prohibitive. Furthermore, percutaneous radiofrequency sympathicolysis may be an effective procedure, but its long-term results are not superior to surgical sympathectomy. On the other hand, surgical upper dorsal (T2-T3) sympathectomy achieves excellent long-term results and the thoracoscopic approach has supplanted the open procedures. Despite some sequelae, mainly in the form of neuralgia and compensatory sweating which cannot be predicted and may be distressing, surgical sympathectomy remains the best treatment for palmar hyperhidrosis.
The optimal duration for courses of antibiotic therapy following emergency abdominal surgery was examined. The length of postoperative administration was based on the operative findings of contamination versus infection and the degree of the latter. A total of 163 patients (mean APACHE II score 7) were stratified into four groups: group 1 (60 patients), no postoperative antibiotics; group 2 (32), antibiotic therapy for 24 h; group 3 (48), administration for 48 h; and group 4 (23), antibiotic therapy for 72 h to 5 days. Three patients (2 per cent) died. Wound infection developed in 12 patients (7 per cent) and postoperative intra-abdominal infection in two (1 per cent). Antibiotics were stopped according to the protocol in 28 patients in spite of continued fever; one developed a subhepatic abscess and three had wound infections. Distinguishing contamination from infection and operative stratification of the latter allowed a successful 'minimal' postoperative antibiotic policy to be employed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
