Objective To present the changing of the parameters of orbital volume after endoscopic transethmoid medial orbital wall decompression combined with the endoscopic transethmoid intraconal fat-removal orbital decompression in thyroid associated ophthalmopathy (TAO).Methods A retrospective chart was reviewed in 11 patients (20 eyes) receiving orbital decompression for the treatment of exophthalmos secondary to TAO from September 2014 to August 2015. All patients diagnosed TAO were in stable and inactive phase at least for 6 months. High-resolution computed tomography (HRCT) scan were performed in all patients before and 3-month after surgery. CT scan of orbit and computer-aided measurement software were used to measure the exophthalmos. Changing of the parameters of orbital volume were recorded for analysis its relationship with the amount of proptosis reduction.Results The exophthalmos was signiifcantly decreased after surgery. Medial rectus volume, fat volume and orbital volume were larger postoperatively. The changing of rectus volume and fat volume both had negative correlationship with the amount of proptosis.Conclusions The thickening of medial rectus 3-month postoperative may due to the removing of medial wall of orbit during the surgery. The stimulation of the surgery may be another reason. The changing of rectus volume and fat volume both had negative correlationship with the amount of proptosis.

[Abstract] Objective To investigate the optimal screw configuration for internal fixation of femoral neck fractures based on anatomic analysis on radiologic imaging. Methods From January to February 2017, thirty proximal femurs of 15 nonnal adults from Picture Archiving and Communication Systems (PACS) of Paople' s Hospibal of Anji were constructed by CT. 8 males and 7 females with a mean age of (43±8. 5) years (ranging from 28 to 63 years) .The medial femoral neck sections (FNS) were projected on the lateral femoral trochanteric wall. The simulated three screw configurations in the projection of FNS include: two inverted equilateral triangles symmetrized to the axis of the FNS (IET-FNS group) or the coronal axis of the proximal femur (IET-PF group) and an obtuse triangle (OT group).The distance between the screws, the distance between the centre of the FNS and the screws, and the area ratio of the triangle/FNS were calculated. Results The projection of the FNS on the lateral femoral trochanteric wall was displayed as a rotating forward ellipse. Measurements of distance between screws

OBJECTIVETo study the changes in pelvic floor morphology and relationships of the pelvic organs in patients with outlet obstructive constipation (OOC).

METHODSFifty-nine OOC patients and 12 healthy volunteers were examined by simultaneous pelvic four-contrast defecography, including pelvicography, vaginal opacification, voiding cystography and defecography. The levels of perineum, peritoneum and bladder, and anorectal angle were measured and recorded.

RESULTSAmong the 59 OOC patients, 46 cases of internal rectal prolapse (IRP), 29 cases of pelvic floor hernia, 7 cases of rectocele (RC), 7 cases of spastic pelvic floor syndrome (SPFS), 5 cases of descending perineum syndrome were diagnosed by pelvic four-contrast defecography. Six cystoceles and 10 uterine prolapses were also found by pelvic four-contrast defecography. Compared with healthy volunteers, OOC patients had significantly large anorectal angles during defecation (P<0.05), abnormality descending of perineum during rest and defecation (P<0.05, P<0.01), and a deep pouch of Douglas during defecation (P<0.01). OOC patients combined with urinary system symptoms had an abnormal descent of the bladder during rest and defecation (P<0.05, P<0.01).

CONCLUSIONPelvic four-contrast defecography is an effective method for the diagnosis of IRP, RC, pelvic floor hernia, peritoneocele, cystocele and uterine prolapse, and is helpful in the selection of proper surgical procedures for the treatment of OOC.
