[Show abstract][Hide abstract] ABSTRACT: Open splenectomy and devascularization are effective treatments for cirrhotic patients with severe thrombocytopenia and variceal bleeding. However, it remains controversial whether laparoscopic splenectomy (LS) and devascularization (LSD) can be indicated and beneficial in these patients.
A systematic review of the efficacy and safety of LS and LSD for patients with liver cirrhosis and portal hypertension was undertaken to clarify controversy about their utilization in such patients.
A systematic search strategy was performed to retrieve relevant studies from PubMed and Embase.com. The literature search and data extraction were independently performed by two reviewers.
Sixteen articles met the inclusion criteria. The methodology of the identified articles was poor. Six hundred and fifty-one patients, including 478 LS patients and 173 LSD patients, were involved in efficacy and safety evaluations. There was wide variability in the outcome measures between studies. There was only one death in the patients underwent LSD. Reported major complications included post-operative bleeding requiring re-surgery, pancreatic leakage and gastric perforation. Seven studies were identified with comparisons between laparoscopic and open procedures. No meta-analysis was possible because of heterogeneity between studies and lack of randomization.
The publications reviewed revealed LS and LSD to be safe and effective in the setting of liver cirrhosis and portal hypertension. From the comparison articles, laparoscopic procedures appear to be superior to open procedures regarding blood loss, hospital stay, complication rate and liver function impairment. However, it is difficult to draw firm statistical conclusions due to lack of high-quality evidence.

[Show abstract][Hide abstract] ABSTRACT: Duodenal intussusception is a rare entity. To date, only a few cases have been reported in the literature. In this report, a case of duodenal intussusception due to an unusual tumor was presented and the clinical features of this entity were discussed. A 42-year-old man with Peutz-Jeghers syndrome presented with epigastric pain, vomiting, and severe anemia. Computed tomography scan revealed synchronous duodenojejunal and jejunojejunal intussusceptions. An emergency laparotomy revealed a polypoid mass originating from the lateral wall of the descending duodenum with intussusception of the distal duodenum. Histological examination demonstrated a poorly differentiated neuroendocrine carcinoma with muscularis infiltration, vascular invasion, and a Ki-67 index of 20%. A comprehensive literature search revealed 44 English reports that provided adequate descriptions of an additional 47 such cases. Clinical presentation was usually chronic and nonspecific. Diagnostic modalities included ultrasonography, upper gastrointestinal series, computed tomography, and endoscopy. Five patients were due to a non-neoplastic lesion; however, the other 43 patients were secondary to a tumor, benign in 35 cases and malignant in eight cases. Only one patient was treated by endoscopic polypectomy, whereas the remaining underwent open surgeries. Duodenal intussusception is a challenging condition due to its rarity and nonspecific presentation. It should be considered in the differential diagnosis of gastric outlet obstruction, upper gastrointestinal bleeding, pancreatitis, and obstructive jaundice.
