Segmental branching pattern of the left portal vein: Anatomical characteristics and clinical implications.

The existing knowledge on anatomy of segmental branches of left portal vein (LPV) is limited. This study aims to describe the surgical anatomy and variations of LPV and its segmental branching pattern. Forty fresh cadaveric liver dissections were performed.

Clinico-Pathological Caracteristics, Therapeutic Features and Post-operative Course of Colorectal Cancer in Elderly Patients.

Statement Of Problem: 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.

Iatrogenic colorectal Kaposi sarcoma complicating a refractory ulcerative colitis in a human immunodeficiency negative-virus patient.

Kaposi sarcoma is a mesenchymal tumor associated to a human herpes virus-8. It often occurs in human immunodeficiency virus-positive subjects. Colorectal localization is rare.

Retroportal lamina or mesopancreas? Lessons learned by anatomical and histological study of thirty three cadaveric dissections.

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.

Meckel's diverticulum: an exceptional cause of vesicoenteric fistula: case report and literature review.

Unlabelled: Meckel's diverticulum is the most common congenital malformation of the gastrointestinal tract. It can cause complications in the form of ulceration, hemorrhage, intussusception, intestinal obstruction, perforation and, very rarely, vesicodiverticular fistulae as noted in six previously reported cases. 66-year-old woman was presented with an enterovesical fistula.

Huge desmoid tumor of the anterior abdominal wall mimicking an intraabdominal mass in a postpartum woman: a case report.

Desmoid tumors are benign neoplasms that most often arise from muscle aponeurosis and have been associated with both trauma and pregnancy. The etiology of desmoids has not been determined. We report the case of anterior abdominal wall desmoid tumor in a female patient with previous history of cesarean section.

Solid pseudopapillary neoplasm of the pancreas in an old man: age does not matter.

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.

Gastrointestinal bleeding due to an erosion of the superior mesenteric artery: an exceptional fatal complication of pancreatic pseudocyst.

The erosion of a pancreatic pseudocyst into an adjacent artery is a rare and highly lethal complication of pancreatitis with reported death rates of 12% to 40%. The majority of patients had bleeding from the splenic artery, the gastroduodenal artery and the anterior pacreaticoduodenal artery. Exceptionally, some cases with bleeding from the superior mesenteric artery, or hepatic artery were reported.

Histopathologic characteristics and short-term outcomes of colorectal cancer in young Tunisian patients: one center's experience.

Introduction: Colorectal carcinoma (CRC) is generally a disease of persons older than 40 years. Concerning younger patients, controversies still exist regarding features and prognosis of CRC. We performed this study to characterise CRC in young patients (≤ 40 years) as well as to evaluate short-term outcome in comparison with older patients (>40 years) with CRC.

Inflammatory myofibroblastic tumor of the lung: a benign lesion with aggressive behavior.

Inflammatory myofibroblastic tumor is a rare solid tumor that most often affects children and young adults. They present as myofibroblastic cell proliferations accompanied by inflammatory cells made up mostly of plasma cells. Although benign, the tumor may be very aggressive locally.

A wandering spleen presenting as a hypogastric mass: case report.

Wandering spleen is a rare condition characterized by the absence or underdevelopment of one or all of the ligaments that hold the spleen in its normal position in the left upper quadrant of the abdomen. It is an uncommon clinical entity that mainly affects children. Among adults it most frequently affects women of reproductive age, in whom acquired laxity of the splenic ligaments is usually the cause.

Internal supravesical hernia - a rare cause of intestinal obstruction: report of two cases.

Supravesical hernias develop at the supravesical fossa between the remnants of the urachus and the left or right umbilical artery. They are exceptional and are often the cause of intestinal obstruction. We report two cases of surgically proven internal supravesical hernias presenting with small bowel obstruction.

Exceptional cause of bowel obstruction: rectal endometriosis mimicking carcinoma of rectum--a case report.

Endometriosis with intestinal serosal involvement is not uncommon in women of childbearing age. However, endometriosis presenting as colon obstruction is rare and occurs in less than 1% of cases. The Lack of pathognomonic signs makes the diagnosis difficult, mostly because the main differential diagnosis is with neoplasm, even during the intervention.

[Anatomic variations of the hepatic artery : a study of 33 cases and review].

Background: The hepatic artery is prone to numerous anatomic variations dictated by certain variables of the organogenesis. Aim : To research study the anatomic variations of the hepatic artery as well as their implications within surgical practice.

Methods: Study of a post-mortem series of 33 cases of dissection of the hepatic pedicle with fresh corpses (deaths amounting no longer than 24 hours), carried out in conditions that are quite close to those met with the living ones.

Intussusception caused by an inverted Meckel's diverticulum: a rare cause of small bowel obstruction in adults.

Adult intussusception due to Meckel's diverticulum is an uncommon cause of intestinal obstruction. However, the surgeon should still be suspicious of this condition since the non specific symptoms and the rarity of it make a preoperative diagnosis uncertain. Considering the secondary nature of adult intussusception and the necessity of early surgical intervention to avoid morbidity and mortality, we report one case of intussusception due to Meckel's diverticulum in an adult.

A rare cause of proximal intestinal obstruction in adults - annular pancreas: a case report.

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.
