Comparative StudyComparative evaluation of immune response after laparoscopical and open total mesorectal excisions with anal sphincter preservation in patients with rectal cancer.
The study of immune response of open versus laparoscopical total mesorectal excision with anal sphincter preservation in patients with rectal cancer has not been reported yet. The dissected retroperitoneal area that contacts directly with carbon dioxide is extensive in laparoscopic total mesorectal excision with anal sphincter preservation surgery. It is important to clarify whether the immune response of laparoscopic total mesorectal excision with anal sphincter preservation (LTME with ASP) in patients with rectal cancer is suppressed more severely than that of open surgery (OTME with ASP). This study was designed to compare the immune functions after laparoscopic and open total mesorectal excision with anal sphincter preservation for rectal cancer. ⋯ There are no differences in immune responses between the patients having laparoscopic total mesorectal excision with anal sphincter preservation and those undergone open surgery for rectal cancer.

Case ReportsBouveret's syndrome complicated by a distal gallstone ileus.
Gastric outlet obstruction caused by duodenal impaction of a large gallstone migrated through a cholecystoduodenal fistula has been referred as Bouveret's syndrome. Endoscopic lithotomy is the first-step treatment, however, surgery is indicated in case of failure or complication during this procedure. ⋯ As the simplest and the least morbid procedure, endoscopic stone retrieval should be attempted in the treatment of patients with Bouveret's syndrome. When it fails, surgical lithotomy consisting of simple enterotomy may solve the problem. Although cholecystectomy and cholecystoduodenal fistula breakdown is unnecessary in every case, conditions may urge the surgeon to perform such operations even though they carry high morbidity and mortality.

Alterations of intestinal mucosa structure and barrier function following traumatic brain injury in rats.
Gastrointestinal dysfunction is a common complication in patients with traumatic brain injury (TBI). However, the effect of traumatic brain injury on intestinal mucosa has not been studied previously. The aim of the current study was to explore the alterations of intestinal mucosa morphology and barrier function, and to determine how rapidly the impairment of gut barrier function occurs and how long it persists following traumatic brain injury. ⋯ Traumatic brain injury can induce significant damages of gut structure and impairment of barrier function which occur rapidly as early as 3 hours following brain injury and lasts for more than 7 days with marked mucosal atrophy.

Comparative Study Clinical TrialFormalized therapeutic guideline for hyperlipidemic severe acute pancreatitis.
To investigate a formalized therapeutic guideline for hyperlipidemic severe acute pancreatitis (HL-SAP). ⋯ Penta-association therapy is an effective guideline in the treatment of hyperlipidemic severe acute pancreatitis at its early stage (within 72 hours).

Long-term effect of stent placement in 115 patients with Budd-Chiari syndrome.
To report the long-term effect of stent placement in 115 patients with Budd-Chiari syndrome (BCS). ⋯ Patients with BCS caused by short length obstruction can be treated by IVC stent placement, HV stent placement or both IVC and HV stent placement depending on the sites of obstruction. The long-term effect is satisfactory. Anticoagulants are strongly recommended after the procedure especially for BCS patients caused by segmental occlusion.
