Increased lymph node evaluation has been associated with improved survival rates in patients with pancreatic cancer. We sought to evaluate the trends and factors associated with lymph node examination over time and the effects on survival. ⋯ We observed a significant increase in the number of lymph nodes evaluated with pancreas cancer resection over time. Lymph node evaluation was significantly associated with patient, tumor, and treatment characteristics. Our results suggest that adequate lymph node evaluation is associated with improved survival.

Review Meta Analysis
Anastomotic reinforcement with omentoplasty following gastrointestinal anastomosis: A systematic review and meta-analysis.
Anastomotic leak is a potentially devastating complication following gastrointestinal anastomosis. Some surgeons believe that reinforcing the anastomosis with omentum reduces the incidence and severity of anastomotic leak. A comprehensive electronic search of EMBASE, Medline, Web of Science and Cochrane databases was performed. ⋯ In colorectal surgery there was no significant difference in anastomotic leak rate (5.0% vs 8.4%; POR: 0.50; 95% CI 0.21 to 1.17) or in-hospital mortality (4.2% vs 4.1%; POR: 0.90; 95% CI 0.34 to 2.41). The results of this analysis show that omentoplasty significantly reduced the rate of anastomotic leak following esophageal anastomosis but these results were not observed in colorectal anastomosis. Omentoplasty could be used as an adjunct technique to reduce the incidence of anastomotic leak in oesophageal anastomosis.

Pathologic or osteoporotic femoral neck fractures usually treated with joint replacement surgery rather than joint-preserving surgery because multiple screw fixation has a high risk for fixation failure and nonunion as well as the need for a postoperative protection period. However, joint-preserving surgery might be preferable in high-risk patients with short life expectancy due to advanced disease. Recently introduced hollow-perforated screws are devices for achieving percutaneous fixation by simultaneous injection to the weak bone area through its multiple side holes. We report our experience of surgical treatment of femoral neck fractures by controlled bone cement injection into the femoral head and neck through a modified hollow-perforated screw in patients with advanced cancer. ⋯ This current surgical method could be useful in patients with short life expectancy because of quick pain relief, early return to ambulation, simple operative procedures and short hospital stay. The modified hollow perforated screw which has a diversity of side hole locations for the regulation of bone cement injection into the planned area seems useful for selective femoral neck fractures.

Review Meta Analysis Comparative Study
Total thyroidectomy versus lobectomy as initial operation for small unilateral papillary thyroid carcinoma: A meta-analysis.
Consensus guidelines have recommended total thyroidectomy for papillary thyroid carcinoma (PTC) > 1 cm. However, the optimal surgical approach for small and unilateral (≤1 cm) PTC remains controversial. ⋯ TT was associated with lower recurrence rates, possibly due to a more complete nodal dissection of the central neck compartment at the time of initial surgery. Based on these data, it is unclear to establish a definitive correlation between the extent of thyroid resection and long-term survival rates due to the small number of mortality events. However, there is a trend toward lower mortality rates in the TT group. Other factors need to be taken into consideration while planning thyroid resection for small PTC, such as multifocality, locoregional involvement, mode of presentation and age at diagnosis. Refinement of current guidelines for the optimal surgical management of PTC <1 cm may be warranted.

Review Meta Analysis Comparative Study
Short-course preoperative radiotherapy with immediate surgery versus long-course chemoradiation with delayed surgery in the treatment of rectal cancer: a systematic review and meta-analysis.
Long-course chemoradiotherapy (LCRT) with delayed surgery or short-course radiotherapy (SCRT) with immediate surgery is probably the most frequent regimen in the treatment of rectal cancer. Debate is still going on whether SCRT or LCRT is more effective. So we performed this meta-analysis to evaluate the safety and efficacy of SCRT with immediate surgery versus LCRT with delayed surgery for the management of rectal cancer. ⋯ SCRT with immediate surgery is as effective as LCRT with delayed surgery for treatment of rectal cancer in terms of OS, DFS, LRR, DMR, Sphincter preservation rate, R0 resection rate and late toxicity. Though LCRT increased pCR rate, LCRT also increased acute toxicity compared with SCRT. SCRT is a better choice in centers with a long waiting list or lack of medical resources.
