Objective To explore the feasibility of a novel technique of anvil placement in combined use of laparoscopic and thoracoscopic Ivor Lewis esophagectomy. Methods From June 2011 to October 2012, we performed a novel technique of minimally invasive Ivor Lewis esophagogastrectomy in 20 patients with midthoracic esophageal cancer.The anvil was placed to connection with the esophageal stump under thoracoscopic vision, and an apical pleural stomach esophagus anastomosis was performed by using normal stapling. Results The mean operation time lasted for 200 minutes (150-300 minutes) with a mean blood loss of 180 ml (150-250 ml) without blood transfusion.The mean number of lymph nodes resected was 18 (12-44).No additional incision was required. There were no complications at post-operation and no anastomic leakage.The patient’s hospital stay lasted a mean of 10 days (8-12 days) .Follow-up reviews were conducted for 6 months and no recurrence was found in all the 20 patients. Conclusion Laparoscopic and thoracoscopic Ivor Lewis esophagectomy with novel technique of anvil placement for the treatment of esophageal carcinoma ensures the feasibility and safety.

OBJECTIVE: To observe the characteristics of serum protein in patients with benign paroxysmal positional vertigo (BPPV) during the symptomatic period. METHOD: Fifty-five patients with BPPV and 58 control subjects were enrolled in the study. All the patients underwent the Dixe-Hallpike and Roll maneuver to confirm the type of BPPV. The average time of onset was (1.0 ± 0.8)days in the group of BPPV. The clinical features and the laboratory tests of serum protein electrophoresis, blood counts, and liver and kidney function were performed in both groups. RESULT: The levels of serum albumin (Alb), α1 globulin, α2 globulin and β globulin of BPPV group did not differ statistically in the two groups (P > 0.05); The γ-globulin levels were significantly higher in patients with BPPV than in controls (P < 0.05). CONCLUSION The γ-globulin levels are increased when BPPV is attacking.

Objective To determine whether an increased number of transrectal biopsy cores improves the accuracy of biopsy Gleason score. Methods This study reviewed a total of 86 patients who were diagnosed as prostate cancer by transrectal needle biopsy and subsequently underwent radical prostatectomy (RP) without neoadjuvant therapy.The rate of grading concordance between biopsy and RP specimens was analyzed by dividing these patients into 2 groups according to the biopsy cores:group A,46 patients who underwent transrectai biopsy sampling of 6 cores,and group B,40 patients who underwent biopsy sampling of 13 cores. Results The concordance between prostate biopsy and radical prostatectomy Gleason score was 65.0%and 34.8% for 13 core and 6 core biopsy,respectirely (P＜0.05).Furthermore,these findings tended to be more prominent as the biopsy Gleason score was lower.Multivariate analysis identified the number of biopsy cores and percent of positive biopsy cores as independent predictors of accurate Gleason grading regardless of other parameters examined in this study. Conclusion Extended needle biopsy may increases the accuracy of biopsy Gleason score for assessing final prostate cancer grade.

Objective: Using previous total mesorectal excision with pelvic autonomic nerve preservation (PANP+TME) and simple total mesorectal excision (TME) without emphasis on retained nerves as control, we explore the advantages of nerve plane-oriented laparoscopic total mesorectal excision (NPO+LTME) on urinary and sexual function. Methods: A retrospective cohort study was carried out. Case inclusion criteria: (1) male patients with pathologically confirmed middle and low rectal adenocarcinoma (4 to 11 cm from the anus); (2) stage T1-2tumor; (3) normal sexual life before operation. Exclusion criteria: (1) no pathological diagnosis before surgery; (2) local recurrence or distant metastasis; (3) preoperative neoadjuvant chemoradiotherapy; (4) opensurgery and laparoscopic surgery conversionto open; (5) no follow-up data. According to the above criteria, clinical data of 173 male patients with low and middle rectal adenocarcinoma who underwent radical operation for laparoscopic rectal cancer from July 2003 to July 2018 at the Department of Gastrointestinal Surgery, Wuhan University People′s Hospital were collected. According to different surgical methods, patients were divided into TME group (58 cases), PANP+TME group (63 cases) and NPO+LTME group (52 cases). There were no significant differences in the baseline data including age, body mass index and pathological examination between the 3 groups (all P>0.05). The nerve plane referred to the nerve, the adipose tissue, the extremely finecapillaries around the nerve with overlying fine membranous tissue. NPO+LTME referred to the process of laparoscopic TME guided by the nerve plane, performing in the loose connective tissue between the nerve plane and the rectal properfascia, in order to ensure the integrity of the nerve plane, and maximally protect the patient's urinary and reproductive functions. The operation time, intraoperative blood loss, urinary catheter removal time, urinary function grading, postoperative first erection time, and erectile function and ejaculation function were observed and compared among the 3 groups at 3- and 6-month after operation. Results: In the NPO+LTME group, the PANP+TME group and the TME group, the operation time was (181.9±24.5) minutes, (176.7±29.2) minutes and (137.7±16.2) minutes, respectively (F=54.868, P<0.001); the intraoperative blood lost was (6.0±1.4) ml, (6.5±1.8) ml and (12.8±4.6) ml, respectively (F=95.016, P<0.001); the time to postoperative removal of the catheter was (2.4±1.1) days, (3.7 ±1.7) days and (6.5±2.4) days, respectively (F=79.409, P<0.001); the first postoperative erection time was (1.6±0.6) days, (8.9±2.7) days and (15.9±6.8) days (F=177.677, P<0.001), respectively, whose differences were all statistically significant (all P<0.01). In comparison of urinary function grading, the proportion of grade I (normal function, no urinary dysfunction) in the NPO+LTME, the ANP+TME group and the TME group was 84.1% (53/63), 39.7% (23/58) and 19.2% (10/52), respectively, and the difference was statistically significant (H=52.915, P<0.001). At postoperative 3- and 6-month, proportion of patients with grade I erectile function (normal erectile function) was 77.8% (49/63) and 85.7% (54/63), 44.8% (26/58) and 53.4% (31/58), 28.8% (15/52) and 48.1% (25/52) in the NPO+LTME group, the PANP+TME group, and the TME group, respectively. The differences were statistically significant (H=91.709, P<0.001; H=79.692, P<0.001). The proportion of patients with grade I ejaculation function (with ejaculation, no abnormalities in routine semen examination before and after surgery) at 3- and 6-month after surgery in the NPO+LTME group, the PANP+TME group and the TME group was 82.5% (52/63) and 87.3% (55/63), 53.4% (31/58) and 60.3% (35/58), 28.8% (15/52) and 46.1% (24/52), respectively. The differences were statistically significant as well (H=86.543, P<0.001; H=78.667, P<0.001). Patients in the NPO+LTME group had no grade III erections and ejaculation disorders. Conclusion The surgical procedure of NPO+LTME can promote the recovery of postoperative neurological function and preserve urination and sexual function better.
