Objective and background: Despite its importance in pancreatic head carcinoma, the retroportal lamina is still under studied, with only two anatomical cadaveric dissections in the English literature, with recent controversies about the concept of a mesopancreas. Methods: Resection of the mesopancreas was performed in 33 fresh cadavers. The pancreas and mesopancreas were separated from each other and the mesopancreas was immunohistochemically investigated. Results: The retroportal lamina is roughly rectangular in shape. Its dimensions are: height 6.2cm (5-8), 2.5cm wide (1.5-4). It contains a right hepatic artery arising from the superior mesenteric artery in 13.3% of cases. Microscopic examination revealed areolar tissue, adipose tissue, peripheral nerve, nerve plexus, lymphatics and capillaries. However, fibrous sheath and fascia were not found around these structures. Conclusion: A right hepatic artery arising from the superior mesenteric artery is a frequent anatomic variation. Surgeons must be aware of this to ensure the integrity of the hepatic artery blood supply in patients treated by pancreaticoduodenectomy. Despite controversy about the reality of the mesopancreas (postulated in analogy to the mesorectum), because of the absence of fibrous sheath or fascia, its complete removal in pancreatic head carcinoma is feasible by a subadventitial dissection of the superior mesenteric artery which can be considered as the real limit of the mesopancreas. © 2013 Surgical Associates Ltd.

Hepatitis B virus and hepatitis C virus are the two most common causes of chronic liver disease in the world. Dual infection with hepatitis B virus and hepatitis C virus, whose prevalence is underestimated, is characterized by a more severe liver injury, a higher probability of liver cirrhosis and a higher incidence of hepatocellular carcinoma. Treatment of these patients represents a therapeutic challenge. We report the case of an hepatitis B virus-hepatitis C virus co-infected patient, which particularly illustrates the interactions between these two viruses and therapeutic problems caused by the dual infection. HCV was initially dominant, which indicated a combination therapy by pegylated interferon and ribavirin. This treatment was associated with an early virological response of the HCV but an increase of HBV DNA occurred, requiring the use of a nucleoside analogue. A good response was obtained for the HBV but a relapse of HCV was noted, posing a problem for therapeutic decision. © 2012 Elsevier Masson SAS.

Solid pseudopapillary tumor (SPN) of the pancreas is a rare tumor, but has favorable prognosis. It is typically observed in young women. Only few cases have been reported in young men. We report the observation of a 73-year-old man presented with a palpable mass in the left upper abdomen. CT scan showed 10 cm mass at the tail of the pancreas. This mass had mixed cystic and solid components. The patient underwent a distal pancreatectomy and splenectomy. SPN of the pancreas was diagnosed based on histopathological features. The patient recovered uneventfully and didn't receive adjuvant therapy. A CT scan performed 16 months postoperatively showed no evidence of disease recurrence. Although SPN of the pancreas is typically observed in young women, the diagnosis should not be discounted in old male patients. Male patients and those with old age, atypical histopathology and incomplete resection may have a higher risk of recurrence and death, deserving particular attention.

Purpose: The Tokyo guidelines for diagnostic criteria and severity assessment of acute cholecystitis (AC), published in 2007, recommend early laparoscopic cholecystectomy (ELC) be done as soon as possible after the onset of symptoms. We conducted this study to analyze the changes in the therapeutic strategy for AC in a surgical center in Tunisia after the Tokyo guidelines were published. Methods: Between January, 2005 and January, 2013, 649 patients underwent cholecystectomy for AC at the Department of Surgery, Mohamed Tahar Maamouri Hospital in Nabeul, Tunisia. The study period was subdivided into before (n = 192) and after (n = 457) the publication of the Tokyo guidelines, that is, prior to and including 2007, and from 2008 onward, respectively. We reviewed patient records retrospectively to collect demographic data, biochemical data, radiological findings, and postoperative outcomes. All these factors were compared between the groups. Results: The duration of symptoms before surgery was significantly longer before 2008 (p = 0.018). ELC was significantly more frequent after 2008 (p = 0.001). Laparoscopic surgery was converted to open surgery in 16.1 % of patients before 2008 vs. 7.8 % of patients after 2008 (p = 0.02). There were no significant differences in bile duct injury or postoperative complications between the groups. The length of preoperative, postoperative, and total hospital stay was longer before 2008. Conclusions: ELC is a safe and effective therapeutic strategy for AC. The Tokyo guidelines resulted in a significant increase in the number of ELCs being performed and significantly reduced preoperative and total hospital stay without increasing intra- and postoperative complications. Importantly, ELC reduced medical costs, which is crucial for a country with limited resources, such as Tunisia. © 2015 Springer Japan

Gastric outlet obstruction (GOO) is a rare complication of peptic ulcer disease (PUD). The endoscopic balloon dilatation (EBD) associated with medical treatment of Helicobacter pylori is a successful method in the management of pyloric stenosis. The aim of this study was to describe epidemiological, clinical, and endoscopic characteristics of GOO related to PUD and to evaluate the effectiveness, safety, and outcome of EBD.In a retrospective study of patients seen between 1999 and 2009 with symptoms of GOO secondary to PUD, pyloro-bulbar stenosis was confirmed by endoscopic examination. Balloon dilatation was performed when obstruction persisted after treatment with double-dose proton-pump inhibitor (PPI) intravenously for 7-10days. The H. pylori status was assessed with histology, and eradication therapy was prescribed for infection.A total of 45 consecutive patients (38 males, 7 females median age, 51.9years; range, 20-58years) with symptoms of GOO secondary to PUD underwent EBD. Median follow-up time of the 45 patients was 32months (range, 4-126months). The immediate success rate of the procedure was 95.5%. Clinical remission was noted in 84.4% of the patients. Remission without relapse was observed in 55.8%, 30months after the dilatation. Pyloric stenosis relapsed in 15 patients (39.5%) after a median period of 22.9months. The dilatation was complicated in three patients (6.7%, two perforations and one bleeding). A total of 13 patients (29%) underwent surgery. H. pylori was found to be positive in 97.7% of the patients, and was eradicated in 78.4% of them. Smoking and failure of H. pylori eradication were associated with the relapse of the stenosis.EBD is a simple, effective, and safe therapy for the GOO related to PUD, producing short- and long-term remission.

Gastro-intestinal stromal tumors (GISTs) of the appendix are a rare entity. To date, only eight cases has been described in the literature, most of which have been of the benign type. We report a new case of an appendiceal GIST in a 75-year-old man. The tumor was discovered when the patient presented with acute appendiceacal peritonitis. Preoperative diagnosis of appendiceal GIST was rarely done as tumors were usually associated with appendicitis-like symptoms.

Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the descending part of the duodenum. It is one of the few congenital anomalies of the gastrointestinal tract which can produce symptoms late in life. In adults, the factors initiating symptoms are recurrent pancreatitis, duodenal stenosis at the site of the annulus, or duodenal or gastric ulceration. We report a new case involving a 24-year-old woman hospitalised for epigastric pain, nausea and vomiting. Radiological examination was consisted with an annular pancreas. At operation a complete obstruction of the second part of the duodenum was found, caused by an annular pancreas, no other congenital anomaly of the intra-abdominal organs was noted. A gastroenterostomy was performed.

Colorectal cancer is predominantly a disease of elderly people and is a major cause of morbidity and mortality in the elderly population. The geriatric colorectal population is a very heterogeneous group, including patients with excellent health status and others with comorbid conditions, functional dependency, and limited life expectancy. On the other hand, the effectiveness of surgery for colorectal cancer depends on it being carried out safely, which allows most patients to return to productive lives, with an improved post-operative life expectancy or at least one that is not diminished by the surgery. Materials and Methods: This work is a descriptive study of a retrospective cohort, based on administrative databases, of all patients with colorectal cancer diagnosed or treated in our institution. We extracted data on sociodemographic characteristics, comorbidity, type of cancer, stage of cancer, type of treatment received, post-operative complications and cause of post-operative death. We compared differences between an elderly group (Group A) (age >75 years) and a group of patients below 75 years (Group B). R esults: We found that elderly patients with colorectal cancer were more likely to be operated in emergent conditions, had more non-specific complications and more post-operative mortality than patients below 75 years. On the other hand, tumours stages, tumours characteristics and post-operative specific morbidity have been proved to be similar, both in Group A and Group B patients. C onclusion: These results suggest that surgery is feasible and can be safe for patients above 75 years, but it needs much more evaluation of comorbidities, per- and post-operative intensive care to avoid post-operative non-specific complications.
