Complicated liver echinococcosis: 30 years of experience from an endemic area.

Background and Aims: Although declining, cystic echinococcosis is still a serious public health issue in Greece. This study evaluated the clinical features, management, and short-term outcome of patients with complicated liver echinococcosis. Material and Methods: A total of 227 patients who were operated on for 322 echinococcal cysts of the liver were retrospectively evaluated. Patients were divided into those with complicated disease (53.7%) and those with noncomplicated disease (46.3%). Intrabiliary rupture (34.4%), cyst infection (32.7%), and their combination (24.5%) were the most common complications. Demographic characteristics, previous hydatid cyst surgery, cyst multiplicity and location, presenting symptoms and signs, types of complicated disease, operative procedures performed, postoperative complications, and hospital stay were assessed. Results: Patient demographics and cyst characteristics demonstrated no significant difference between the two groups. The complicated disease group had significantly more pronounced clinical presentations and higher postoperative morbidity. Choice of surgical procedure depended upon cyst location and surgeon preference. Both conservative and radical procedures were performed, supplemented with additional management of the biliary tree when indicated. Conclusions: Complicated liver echinococcosis demonstrates several distinct features that differentiate it from the noncomplicated disease. Frequently severe clinical manifestations, complexity of surgical management, and the increased postoperative complications characterize complicated liver echinococcal disease.

Amyand's hernia-a vermiform appendix presenting in an inguinal hernia: a case series

IntroductionA vermiform appendix in an inguinal hernia, inflamed or not, is known as Amyands hernia. Here we present a case series of four men with Amyands hernia.Case presentationsWe retrospectively studied 963 Caucasian patients with inguinal hernia who were admitted to our surgical department over a 12-year period. Four patients presented with Amyands hernia (0.4%). A 32-year-old Caucasian man had an inflamed vermiform appendix in his hernial sac (acute appendicitis), presenting as an incarcerated right groin hernia, and underwent simultaneous appendectomy and Bassini suture hernia repair. Two patients, Caucasian men aged 36 and 43 years old, had normal appendices in their sacs, which clinically appeared as non-incarcerated right groin hernias. Both underwent a plug-mesh hernia repair without appendectomy. The fourth patient, a 25-year-old Caucasian man with a large but not inflamed appendix in his sac, had a plug-mesh hernia repair with appendectomy.ConclusionA hernia surgeon may encounter unexpected intraoperative findings, such as Amyands hernia. It is important to be prepared and apply the appropriate treatment.

Autoimmune pancreatitis versus pancreatic cancer: a comprehensive review with emphasis on differential diagnosis.

BACKGROUND Autoimmune pancreatitis (AIP) is a rare form of chronic pancreatitis with a discrete pathophysiology, occasional diagnostic radiological findings, and characteristic histological features. Its etiology and pathogenesis are still under investigation, especially during the last decade. Another aspect of interest is the attempt to establish specific criteria for the differential diagnosis between autoimmune pancreatitis and pancreatic cancer, entities that are frequently indistinguishable. DATA SOURCES An extensive search of the PubMed database was performed with emphasis on articles about the differential diagnosis between autoimmune pancreatitis and pancreatic cancer up to the present. RESULTS The most interesting outcome of recent research is the theory that autoimmune pancreatitis and its various extra-pancreatic manifestations represent a systemic fibro-inflammatory process called IgG4-related systemic disease. The diagnostic criteria proposed by the Japanese Pancreatic Society, the more expanded HISORt criteria, the new definitions of histological types, and the new guidelines of the International Association of Pancreatology help to establish the diagnosis of the disease types. CONCLUSION The valuable help of the proposed criteria for the differential diagnosis between autoimmune pancreatitis and pancreatic cancer may lead to avoidance of pointless surgical treatments and increased patient morbidity.

Inadvertent insertion of a nasogastric tube into the brain: case report and review of the literature

The inadvertent insertion of a nasogastric tube (NGT) into the brain of a trauma patient with skull base fractures is reported. A 52-year-old male with head trauma was referred following a car accident with an NGT in situ. Serosanguineous fluid was withdrawn from the NGT, which was considered to be an indication of gastrointestinal bleeding, and cold saline lavage was performed. Skull X-rays revealed intracranial position and coiling of the NGT and pneumocranium. The NGT was immediately removed manually. The patient finally went through neurosurgical operation because of an extradural hematoma, with normal postoperative course and outcome.

Tension-free by mesh-plug technique for inguinal hernia repair in elderly patients.

Background: Elderly patients are steadily becoming a growing part of the population. The aim of this study is to evaluate the outcome of open inguinal hernia repair in patients aged over 65 years. Methods: From January 1999 to December 2008, a total of 719 patients underwent open tension-free inguinal hernia repair with mesh-plug; 301 among them were ≥ 65 years old. Results: Elderly patients had a mean age of 72.4 years (women 3.3%), while the mean age of younger patients was 48.7 years (women 5.7%). According to the ASA score, patients aged ≥ 65 years were at significantly higher risk than the younger patients. Spinal anesthesia was used most frequently in both groups. No significant differences were found in postoperative pain, mortality and recurrence. Morbidity and hospital stay were significantly higher in patients aged ≥ 65 years. Conclusions: Open hernia repair in the elderly is safe and well tolerated, but it is associated with higher morbidity and longer hospitalization.

Umbilical Metastasis as Primary Manifestation of Cancer: A Small Series and Review of the Literature

Umbilical metastasis is a rare manifestation of intra-abdominal cancer. It appears either as the first sign of a primary malignancy or as metastatic site of an already diagnosed cancer, representing an ominous prognostic finding. We report three cases of umbilical metastasis as the first sign of an underlying malignancy. Hypotheses about pathophysiology of umbilical metastasis are based on the embryological origin of the umbilicus and its residual communication with systematic, portal and lymphatic circulation.

Current management of diverticular disease complications.

Diverticular disease is a common problem in the western population and sometimes leads to serious complications such as hemorrhage, bowel stenosis, obstruction, abscesses, fistulae, bowel perforation, and peritonitis. The severity of these complications can differ, and it is not always clear which procedure is indicated in each case and what measures should be followed before bringing the patient into the operating room. Certain operations have high rates of morbidity and mortality, especially in compromised patients. Along with advancements in imaging and minimally invasive techniques, the indications for surgery have currently being adapted to “damage limitation” or “down-staging” protocols, which seem to offer improved results. There are still some questions to be solved in the following years by prospective studies, such as the usefulness of laparoscopic lavage in purulent peritonitis or of Hartmann’s procedure in fecal peritonitis. These indications, based on current literature, are systematically discussed in the present review.

Primary Gallbladder Small Lymphocytic Lymphoma as a Rare Postcholecystectomy Finding

Introduction. Primary lymphoma of the gallbladder is an extremely rare entity with approximately 50 cases reported so far. In many of these cases the presenting symptoms were mimicking symptomatic gallstone disease and the diagnosis was made postoperatively, especially when the preoperative imaging results were far from suspicious for malignant disease. Patients and Methods. We report a case of primary lymphoma of the gallbladder in an 85-year-old man with gallstone disease, who was admitted for elective cholecystectomy 2 months after an episode of acute cholecystitis and pancreatitis. Histological evaluation of the specimen revealed a small lymphocytic lymphoma of the gallbladder. This type of primary gallbladder lymphoma has not been previously reported. Discussion. The most common primary lymphomas of the gallbladder are MALT lymphomas and diffuse large B-cell lymphomas, although a variety of other histological types have been reported. The association of these lesions with chronic inflammation is the most convincing theory for their pathogenesis. For lesions confined to the gallbladder, cholecystectomy is considered to be sufficient, while supplementary chemotherapy significantly improves prognosis in more advanced disease.

A severe case of xanthogranulomatous cholecystitis along with a review of CT indications for nonoperative management including percutaneous drainage.

Backround: Xanthogranulomatous cholecystitis is a rare but severe presentation of cholecystitis characterized by extensive inflammation of the gallbladder wall with characteristic histopathological features. Frequently, the inflammatory mass resembles gallbladder cancer macroscopically, which further complicates therapeutic decisions. Case Presentation: We report a case of xathogranulomatous cholecystitis with characteristic computed tomography findings, which was managed by percutaneous drainage of the gallbladder, giving the opportunity for a delayed elective cholocystectomy with an excellent postoperative outcome. Discussion: Recent studies give emphasis on certain criteria for the differential diagnosis of xanthogranulomatous cholecystitis against carcinoma. Characteristic computed tomography features are usually sufficient to establish the diagnosis with safety and decide a nonoperative management of the disease in the acute phase. Percutaneous gallbladder drainage is regarded as a safe and an efficient method for the initial treatment of severe cases.

Clinical features of colonic diverticular disease

Colonic diverticular disease is extremely common in developed countries. Although the majority of patients with diverticulosis remain asymptomatic, about one-third of the patients manifest the disease with either hemorrhage or inflammation. Diverticulitis may be uncomplicated or complicated by abscess formation, perforation with peritonitis, fistula, intestinal obstruction, or stricture. Controversy exists regarding the aggressiveness of diverticulitis during recurrent attacks of the disease as well as in special groups of patients including immunocompromised patients, young patients, and patients with right-sided disease. Clinical characteristics of symptomatic uncomplicated disease can be similar to irritable bowel syndrome, while acute diverticulitis is sometimes difficult to distinguish from segmental colitis associated with diverticulosis. The considerable clinical overlap between those entities with diverticular disease demonstrates that there are still areas of uncertainty in their physiopathology.
