Objectives: The main purpose of this study was to compare the surgical strategy and clinical outcomes of single-position robotic assisted laparoscopic anterograde bilateral inguinal lymphadenectomy for penile cancer.
Materials And Methods: 21 patients were diagnosis with squamous cell carcinoma and identified from March 2010 to December 2020 in our department. Ten patients were received single-position robotic assisted laparoscopic anterograde bilateral inguinal lymphadenectomy (robot-assisted group), and eleven patients underwent laparoscopic inguinal lymphadenectomy (laparoscopic group). Preoperative physical examination and related auxiliary examinations all indicated bilateral inguinal lymph node enlargement, and there was no distant metastasis patient presented during the follow-up period.
Results: There was no intraoperative conversion to open surgery. The operation time under robot-assisted group was 104 ± 13 min which was significantly shorter than laparoscopic group (136 ± 11 min, P < 0.01). The average number of lymph nodes was 22.2 ± 4.5 of both sides in robot-assisted group, which was statistically different compared with laparoscopic group (15.4 ± 3.1, p < 0.01). Moreover, there was significant difference of hospitalization cost between two groups (CNY 67429 ± 5586 vs 28582 ± 3774, P < 0.01). No differences in operation time, blood loss, and length of stay were recorded.
Conclusions: The single-position robotic assisted laparoscopic anterograde bilateral inguinal lymphadenectomy reveals with shorter operating time, and better surgical effect, Moreover, we prefer to no change the trocars layout and mechanical arm system during the operation.

Background: Inconsistencies in the workup of labral tears in the hip have been shown to result in a delay in treatment and an increased cost to the medical system.
Purpose: To establish consensus statements among Canadian nonoperative/operative sports medicine physicians via a modified Delphi process on the diagnosis, nonoperative and operative management, and rehabilitation and return to play (RTP) of those with labral tears in the hip.

Recent studies indicate that central administration of oxytocin (OT) reduces body weight (BW) in high fat diet-induced obese (DIO) rodents by reducing energy intake and increasing energy expenditure (EE). Previous studies in our lab have shown that administration of OT into the fourth ventricle (4V; hindbrain) elicits weight loss and stimulates interscapular brown adipose tissue temperature (T) in DIO rats. We hypothesized that OT-elicited stimulation of sympathetic nervous system (SNS) activation of IBAT contributes to its ability to activate BAT and reduce BW in DIO rats.

Background: Open pelvic fractures are rare but represent a serious clinical problem with high mortality rates. Acute mortality is often associated with hemorrhage, whereas delayed mortality is most often associated with sepsis and multiple organ failure. We report a case of Wang's classification of type II open pelvic ring fracture with hemorrhagic shock and septic shock from gas gangrene.

Turner syndrome is the most common sex chromosomal abnormality in about 1:2000-2500 live female births. While short stature and delayed puberty are the most common presentations of patients, atypical findings can also be seen. In this article, we present the Turner twins, who were diagnosed during inguinal hernia surgery when bilateral uterus and ovaries were found within the hernia sac.

Neurofibromatosis type 1 (NF-1) is a genetic disorder commonly characterized by café-au-lait macules, neurofibromas and axillary freckling. We present the case of a 20-year-old female who had bilateral neck swellings, and these swellings were misdiagnosed as cervical lymphadenopathy, and the patient was started on anti-tubercular therapy (ATT), but the swellings didn't show any improvement despite 6 months of ATT. Further examination revealed thickening of the greater auricular, supratrochlear and supraorbital nerves, accompanied by an unusual freckling pattern along the thickened nerves, which were suggestive of neurofibromatosis.
