Both microscopic and endoscopic transsphenoidal surgery are effective approaches for nonfunctioning pituitary adenomas. The issue on the comparison of their efficacy and safety remains inconsistent. A thorough search of the literatures (PubMed, EMBASE, MEDLINE) were performed up to March 2017. Studies reporting outcomes of microscopic or endoscopic transsphenoidal surgery on nonfunctioning pituitary adenomas were included. A meta‐analysis was performed focusing on the early stage and long term outcomes. The final search yielded 19 eligible studies enrolling 3847 patients, 389 of them underwent microscopic approach and 3458 of them with endoscopic approach. As to the early stage outcomes, the rate of gross tumor resection was significantly higher in the endoscopic group than that in microscopic group (73% versus 60%, P < 0.001). Meanwhile, endoscopic approach showed priority over microscopy on postoperative hypopituitarism (63% versus 65%, P < 0.001) and CSF leakage (3% versus 7%, P < 0.001). For the long term outcomes, the rate of visual improvement was significant higher in the endoscopic group than that in microscopic group (77% versus 50%, P < 0.001). However, there was no significant difference between the groups regarding the rate of permanent diabetic insipidus and meningitis. The endoscopic approach may be associated with higher rate of gross tumor movement and lower risk of postoperatively complications for treating nonfunctioning pituitary adenoma, when compared with microscopic approach. However, the confidence was shorted due to limited high quality evidence (largely randomized and controlled studies).

The outcomes of laparoscopic adhesiolysis for small bowel obstruction have generally been satisfactory over the short term. However, the long-term outcomes, including recurrence of symptoms and management of recurrence, remain controversial. This study compares the long-term outcomes of a series of laparoscopic and open surgery procedures for the treatment of small bowel obstruction. Patients who underwent adhesiolysis for small bowel obstruction at our institution between 2008 and 2015 were retrospectively reviewed. In total, 156 patients were enrolled, 78 with laparoscopic and 78 with open surgery. Propensity score matching was used to minimize the bias in patient selection. Long-term outcomes included incidence of recurrent symptoms and reoperation. In addition to the comparison of outcomes, risk factor assessment for recurrent symptoms and analysis of detailed information in patients with reoperation were performed. Statistical methods included χ 2 test, Mann–Whitney U test, Cox proportional hazards model, and Kaplan–Meier plots with log-rank comparison. Laparoscopy was performed in a younger population with milder bowel dilation and less complicated etiologies. These factors were used to construct the propensity score model, which yielded a matched cohort of 52 legs in each group. Laparoscopy achieved good short-term outcomes including early recovery of gastrointestinal function, reduced incidence of complications, and shorter hospital stay. For long-term outcomes, while the overall recurrence rate did not differ between the groups (11.5 vs 7.7%), the incidence of reoperation for recurrence was significantly higher in the laparoscopically treated group (7.7 vs 0%, p = .017). The Cox proportional hazards model showed that multiple prior surgeries (≥3 times) were a risk factor for overall recurrence (hazard ratio 7.39, p = .041). Laparoscopic adhesiolysis did not decrease the incidence of recurrent symptoms; rather, it was related to higher incidence of recurrent small bowel obstruction requiring surgical treatment.

With accumulated surgical experience, the contraindications to laparoscopic surgery have been decreasing. Reduced port laparoscopic surgery has been widely adopted for a variety of diseases. However, surgery in patients with anatomic deformities are still a challenge for surgeons, specifically abdominal surgery in patients with severe kyphosis. A 71-year-old man with a diagnosis of ascending colon cancer had severe kyphosis with extremely short stature, secondary to tuberculous spondylitis. Laparoscopic right hemicolectomy was successfully performed with a single umbilical incision plus one port. This is the first reported case involving laparoscopic surgery in a patient with tuberculous kyphosis. The purpose of this report is to describe the surgical skills of reduced port laparoscopic surgery in a patient with altered habitus. With proper planning and a meticulous operation, minimally invasive surgery could be safely achieved.

Our understanding of the mechanisms underlying process in Alzheimer's disease (AD) is far from completion and new therapeutic targets are urgently needed. Recently, the link between dementia and diabetes mellitus (DM) prompted us to search for new therapeutic strategies from glucose metabolism regulators for neurodegeneration. Previous studies have indicated that fibroblast growth factor 21 (FGF21), an attractive and potential therapeutic treatment for DM, may exert diverse effects in the central nervous system. However, the specific biological function and mechanisms of FGF21 on AD is still largely unknown. We report here a study in vivo and in vitro of the neuroprotective effects of FGF21 on cell apoptosis, tau hyperphosphorylation and oxidative stress induced by amyloid β-peptide 25–35. In the present study, the results also further provided evidence for molecular mechanisms by which FGF21 exerted its beneficial effects in neuron and suggested that the regulation of protein phosphatase 2A / mitogen-activated protein kinases / hypoxia-inducible factor-1α pathway may play a key role in mediating the neuroprotective effects of FGF21 against AD-like pathologies., Graphical abstract fx1, Highlights • In vivo and in vitro evidence for Aβ -induced neurodegeneration ameliorated by FGF21. • FGF21 alleviated tau and oxidative stress pathologies in AD rat and cellular models. • PP2A / MAPKs / HIF-1α pathway was involved in the neuroprotective effect of FGF21.

Engineered materials could arrest aircrafts rushing out of runway, but its fragile and can be easily damaged by jet blast exhausted by taking off aircraft nearby. Engineered material unit coating and encapsulation were described in this paper, and a jet blast resistance experiment is designed to quantitatively measure the units resistant capability. In this experiment, a test bed built by units will receive a taking-off Boeing 737-300 aircrafts jet blast for over 60 seconds. The test order decreased distance from aircraft tail to the test bed. And the predicted air velocity and temperature was calculated through aircrafts characteristics contour. All the design made the experiment high reliable and economical. Experimental result indicated that the nearest distance from the test bed to aircraft tail could be 15 meters, and this experiment result has already been used for design of the arresting system in a Chinese civil airport.

Superior mesenteric artery (SMA) syndrome is defined as a compression of the third portion of the duodenum by the abdominal aorta and the overlying SMA. SMA syndrome associated with anorexia nervosa has been recognized, mainly among young female patients. The excessive weight loss owing to the eating disorder sometimes results in a reduced aorto-mesenteric angle and causes duodenal obstruction. Conservative treatment, including psychiatric and nutritional management, is recommended as initial therapy. If conservative treatment fails, surgery is often required. Currently, traditional open bypass surgery has been replaced by laparoscopic duodenojejunostomy as a curative surgical approach. However, single incision laparoscopic approach is rarely performed. A 20-year-old female patient with a diagnosis of anorexia nervosa and SMA syndrome was prepared for surgery after failed conservative management. As the patient had body image concerns, a single incision laparoscopic duodenojejunostomy was performed to achieve minimal scarring. As a result, good perioperative outcomes and cosmetic results were achieved. We show the first case of a young patient with SMA syndrome who was successfully treated by single incision laparoscopic duodenojejunostomy. This minimal invasive surgery would be beneficial for other patients with SMA syndrome associated with anorexia nervosa, in terms of both surgical and cosmetic outcomes.

Toxic epidermal necrolysis (TEN) is a severe adverse drug reaction, which is characterized by erythema, blisters, and/or erosions of the mucous membranes and skin, but intestinal involvement is rare. In contrast, pneumatosis cystoides intestinalis (PCI) is a rare condition associated with a wide variety of underlying diseases, but to date no patient has presented with PCI associated with TEN. A 55-year-old man was admitted to intensive care unit for treatment of TEN caused by phenobarbital. On day 8 after admission, he presented with progressive abdominal distention and hypotension. Computed tomography (CT) showed gas in the superior mesenteric vein and air filled cysts in the walls of the small intestine. He was suspected of having septic shock due to PCI. As there were no indications of bowel ischemia or necrosis, the patient was managed conservatively with antibiotics and oxygen therapy. On day 10 after admission, he was weaned off catecholamines, with CT on day 11 showing complete resolution of gas in the superior mesenteric vein and air filled cysts. To our knowledge, this article describes the first patient presenting with PCI associated with TEN.

Highlights • Unnoticed ingestion of blister packs cause gastrointestinal perforation. • Preoperative diagnosis of foreign body ingestion is often difficult. • Duodenal perforation caused by blister packs is extremely rare. • Perforation in the third portion of duodenum can lead to retroperitoneal abscess. • Despite prompt management, duodenal perforation may be potentially fatal., Introduction Ingestion of foreign bodies is a relatively common clinical problem. Blister packs have been known to be a causative agent of gastrointestinal perforation. We report a rare case of duodenal perforation caused by a blister pack, which was complicated by retroperitoneal abscess and having a poor outcome. Presentation of case A 72 year-old man with a history of dementia presented to the emergency department with a 2-day history of backache. Upon radiological findings, perforated peptic ulcer was suspected. However, emergency laparotomy revealed a blister pack protruding from the posterior wall of the third portion of the duodenum. It was complicated by a widespread retroperitoneal abscess. After removal of the foreign body, the perforation was treated with primary suture repair and an omental patch. However, the patient died two days after operation due to sepsis. Discussion According to a literature review, the ileum is the most common site of perforation caused by blister packs. To our knowledge, duodenal perforations have not been documented to date. Curative treatment often involves emergent surgery. However, duodenal perforation in the third portion may lead to retroperitoneal abscess, which can result in severe sepsis and have a poor outcome. As there is no consensus about an ideal surgical approach, retroperitoneal abscess is one of the clinical challenges for surgeons. Even with prompt management, duodenal perforation may become fatal. Conclusion Unnoticed ingestion of blister packs can cause duodenal perforation. Although prompt management is necessary, duodenal perforation, especially in the third portion, may be potentially fatal.
