RESUMEN

BACKGROUND: Mirizzi syndrome (MS) is a complicated form of longstanding, symptomatic cholelithiasis. According to Beltran Classification MS Type V has been introduced to describe the cholecystoenteric fistula, with or without gallstone ileus. Mirizzi syndrome Type V with double fistula has been reported in the past; however, the triple fistula is an even rarer case, first described in the international literature so far. CASE PRESENTATION: A 77-year-old male was admitted to our surgical department with recurrent episodes of abdominal pain, which initially presented in the last 6 months and was accompanied with jaundice. Computed tomography showed findings of cholelithiasis, pneumobilia and choledocholithiasis. We performed an ERCP, which showed two fistulas of the gallbladder with the pyloric antrum and the duodenum, respectively. Surgical treatment was immediately undergone and during laparotomy, we confirmed these findings. We ligated and dissected these communications. In addition, a third fistula between the gallbladder and the common bile duct was identified. An insertion of a Kehr T-tube into the common bile duct was performed via the gallbladder. After 3 months, the Kehr T-tube was removed and in the subsequent 2 years of follow-up the patient was presented without complications. CONCLUSIONS: Mirizzi syndrome complicated with triple fistula, first described in the international literature, to the best of our knowledge, confirms the long natural history of inflammation.

RESUMEN

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 Serosanguineous fluid was withdrawn from the NGT, which was considered to be an indication of gastrointestinal bleeding, and cold saline lavage was performed.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.

RESUMEN

BACKGROUND: The current study evaluated the effect of time in the severity of the oxidative stress due to pneumoperitoneum. METHODS: Forty Wistar rats were allocated randomly into 2 groups. The 1 h pneumoperitoneum (Pp) group, which was subjected to 60 min of pneumoperitoneum, and the 3 h Pp, to pneumoperitoneum for 180 min. The animals were divided in half. One half of the rats were left resting for 30 min after abdominal desufflation and the other for 8 h. After these two time periods, blood, liver, kidney, lung and small intestine were obtained for biochemical analysis and histopathological examination. RESULTS: In the 3 h Pp, the associated oxidative stress was increased. There was an overt increase in blood and tissue MDA and blood PAB values. The MPO values were significantly higher in the 3 h Pp group in serum, kidneys, and intestine during the early phase of reperfusion and in liver after 8 h of reperfusion. These changes occurred in the presence of light microscopic evidence of greater tissue damage for the 3 h Pp, which were consistent with the fluctuation of the MPO values. CONCLUSION: In our experimental model, we proved biochemically and histologically that time of maintenance of pneumoperitoneum is an additive factor that could cause increased oxidative stress in laparoscopic procedures.

RESUMEN

INTRODUCTION: Idiopathic spontaneous intra-abdominal haemorrhage is a rare, but challenging condition, associated with high mortality if not managed appropriately. The preoperative diagnosis is difficult, despite the recent advances in imaging. We present the clinical manifestations of this condition, as well as the available diagnostic and therapeutic modalities. PRESENTATION OF CASE: We report a case of a spontaneously ruptured dissecting aneurysm of the middle colic artery, which was managed with an emergency laparotomy and aneurysmatectomy. Interestingly, no evidence of vasculitis, infection or collagen disease was discovered during the histopathology examination of the specimen. DISCUSSION: The treatment of idiopathic spontaneous intra-abdominal haemorrhage revolves around patient resuscitation and management of the source of bleeding. In case of a ruptured aneurysm of the middle colic artery, the surgical management includes emergency laparotomy, arterial ligation and resection of the aneurysm. Transarterial embolisation has been suggested as a safe and less invasive alternative approach. CONCLUSION: A ruptured middle colic artery aneurysm should be included in the differential diagnosis of any unexplained intra-abdominal haemorrhage. Aneurysmatectomy is the treatment of choice, with radiologic interventional techniques gaining ground in the management of this entity.

RESUMEN

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.

RESUMEN

INTRODUCTION: A vermiform appendix in an inguinal hernia, inflamed or not, is known as Amyand's hernia. Here we present a case series of four men with Amyand's hernia. CASE PRESENTATIONS: We retrospectively studied 963 Caucasian patients with inguinal hernia who were admitted to our surgical department over a 12-year period. Four patients presented with Amyand's 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. CONCLUSION: A hernia surgeon may encounter unexpected intraoperative findings, such as Amyand's hernia. It is important to be prepared and apply the appropriate treatment.

RESUMEN

INTRODUCTION: Injury of the gallbladder after blunt abdominal trauma is an unusual finding; the reported incidence is less than 2%. Three groups of injuries are described: simple contusion, laceration, and avulsion, the last of which can be partial, complete, or total traumatic cholecystectomy. CASE PRESENTATION: A case of isolated complete avulsion of the gallbladder (near traumatic cholecystectomy) from its hepatic bed in a 46-year-old Caucasian man without any other sign of injury is presented. The avulsion was due to blunt abdominal trauma after a car accident. The rarity of this injury and the stable condition of our patient at the initial presentation warrant a description. The diagnosis was made incidentally after a computed tomography scan, and our patient was treated successfully with ligation of the cystic duct and artery, removal of the gallbladder, coagulation of the bleeding points, and placement of a drain. CONCLUSIONS: Early diagnosis of such injuries is quite difficult because abdominal signs are poor, non-specific, or even absent. Therefore, a computed tomography scan should be performed when the mechanism of injury is indicated.

RESUMEN

BACKGROUND: The most dangerous complication following esophagogastrectomy for esophageal cancer is anastomotic leakage. Surgical interventions described did not have a major impact in reducing the risk of occurrence. On the other hand, pleural tenting has been used for more than a decade by thoracic surgeons to prevent prolonged air leak after formal upper lobectomy with excellent results. METHODS: A retrospective analysis of 114 cases of esophagogastrectomy for cancer of esophagus or cardioesophageal junction is presented. Patients have been divided in 2 groups. In group B modified pleural tenting was used to prevent a potential anastomotic leak, while in group A, the control group, pleural tenting was not used. Evaluation of modified pleural tenting in preventing anastomotic leakage was the aim of the study. RESULTS: The pleural tenting group showed a significant decrease in anastomotic leak. In 1 patient versus 8 in group without pleural tenting the complication appeared (P = .032). The risk for an anastomotic leakage in group without pleural tenting was almost 9 times greater (odds ratio: 9.143, 95% confidence interval: lower bound 1.104, upper bound 75.708). The 30-day mortality, although lower in pleural tenting group, was not statistically significant. CONCLUSIONS: Pleural tenting is a safe, fast, and effective technique for prevention of anastomotic leakage after Ivor Lewis esophagogastrectomy. Subpleural blanketing of intrathoracic anastomosis could diminish the consequences of a possible anastomotic leak.

RESUMEN

Primary pulmonary mucinous cystadenocarcinoma (PMCAC) is an extremely rare cystic neoplasm. A case of a 56-year-old male with a cystic lesion of the right lower lobe is described. Preoperative fine needle aspiration cytology and bronchoscopy were inconclusive. The patient underwent a formal right lower lobectomy and mediastinal lymph node dissection. Diagnosis was established intraoperatively. The biological behavior of primary PMCAC is unknown. Therefore, careful long-term follow-up is considered necessary because of lack of experience globally.

RESUMEN

OBJECTIVES: The aim of this study was to compare the effectiveness of atorvastatin with the sodium hyaluronate/carboxymethylcellulose (HA/CMC, Seprafilm; Genzyme; Genzyme Biosurgery Corporation, Cambridge, MA) in preventing postoperative intraperitoneal adhesion formation in rats. METHODS: Sixty Wistar rats underwent a laparotomy, and adhesions A were induced by cecal abrasion. The animals were divided into 4 groups: group 1, control A; group 2, (A + atorvastatin); group 3, (A + HA/CMC), and group 4, (A + atorvastatin + HA/CMC). The atorvastatin (groups 2 and 4) and HA/CMC (groups 3 and 4) were administered intraperitoneally before the abdominal wall was closed. After 14 days, adhesions were classified by 2 independent surgeons. RESULTS: The adhesion scores (mean +/- standard deviation) for groups 1, 2, 3, and 4 were 2.93 +/- .59, 1.85 +/- 1.07, 1.80 +/- .86, and 1.93 +/- .70, respectively. The differences in adhesion scores among all 3 preventive groups (groups 2, 3, and 4) were statistically significant when compared with the control group (P = .005, P = .002, and P = .009, respectively). CONCLUSIONS: These data suggest that atorvastatin, administered intraperitoneally, is as effective as HA/CMC without an expectable additive effect in preventing postoperative adhesions in rats.

RESUMEN

BACKGROUND: Leiomyomas of esophagus, although rare, are the most frequent benign tumors of esophagus. Aim of this study is the presentation of 7 patients with esophageal leiomyomas who underwent surgical treatment during a 9-year period. METHODS: Epidemiological data (sex, age), the presenting symptoms, diagnostic examinations, tumor location, histopathological findings and the safety and efficacy of surgical resection are analyzed and assessed. RESULTS: 5 men and 2 women with mean age of 56.9 years were operated. In 3 cases the tumor was located at the lower esophagus, while in the other 4 cases, the leiomyoma was found at the median third of esophagus. 4 patients had severe symptoms related to the leiomyoma, such as dysphagia and epigastric pain. All patients underwent a right postolateral thoracotomy with enucleation of the lesion. None of them received resection of part of the esophagus. The mean diameter of the resected tumors was 4.3 cm. The dimensions of leiomyomas were immediately associated with the symptoms. In no case was detected malignancy or recurrence. All patients were relieved from their symptoms, while postoperative morbidity and mortality did not occur. CONCLUSIONS: Esophageal leiomyoma is a benign tumor, which causes symptoms only if its size becomes large. Surgical enucleation is considered to be safe and effective, without complications.

RESUMEN

Approximately 60 cases of biliary papillomatosis have been reported in the world literature, while only 6 cases have been reported to be treated with liver transplantation. This rare disease, which is characterized by relapsing episodes of obstructive jaundice and cholangitis that lead to secondary cirrhosis and death from sepsis or liver failure, it is also considered premalignant because of its frequent malignant transformation (25-50%). We present a case of a 43-year-old white man with papillomatosis of intra- and extrahepatic biliary tree who sought care for repeated episodes of obstructive jaundice and cholangitis. The diagnosis was suspected after endoscopic retrograde cholangiopancreatography and confirmed by liver and common bile duct biopsies. The patient underwent orthotopic liver transplantation with Roux-en-Y hepatico-jejunostomy to treat end-stage liver cirrhosis. Fifteen months' follow-up revealed a patient with normal graft function and with no clinically or laboratory findings of disease recurrence or cancer development.
