ObjectiveTo review the research on the reasons of unplanned reoperation (URP) for degenerative lumbar spine diseases, and to provide new ideas for improving the quality of surgery for degenerative lumbar spine diseases. Methods The literature about the URP of degenerative lumbar spine diseases at home and abroad in recent years was reviewed and analyzed. Results At present, the reasons for URP include surgical site infection (SSI), hematoma formation, cerebrospinal fluid leakage (CSFL), poor results of surgery, and implant complications. SSI and hematoma formation are the most common causes of URP, which happen in a short time after surgery; CSFL also occurs shortly after surgery but is relatively rare. Poor surgical results and implant complications occurred for a long time after surgery. Factors such as primary disease and surgical procedures have an important impact on the incidence of URP. ConclusionThe main reasons for URP are different in various periods after lumbar spine surgery. Interventions should be given to patients with high-risk URP, which thus can reduce the incidence of URP and improve the surgery quality and patients’ satisfaction.

ObjectiveTo examine the cause of failure of mitral valve repair. MethodWe retrospectively anal-yzed the clinical data of 89 consecutive patients with non-rheumatic mitral valve diseases who underwent reoperation for failure of mitral valve repair in our hospital from January 2009 through January 2016. There were 54 males and 35 females at age of 36.2±17.4 years. ResultsThere were 16 patients with reoperation of mitral valve repairs and 73 patients of mitral valve replacements. The failure reasons of initial mitral valve repair were technique-related in 63 patients (70.8%) and valve-related in 18 patients (20.2%). Technique-related causes of repair failure included leaflet suture dehiscence (20 patients, 22.5%), edge-to-edge procedure (11 patients, 12.4%), leaflet thickening or retraction (11 patients, 12.4%), ring dehiscence (8 patients, 9.0%), inappropriate annuloplasty (6 patients, 6.7%), incomplete repair (4 patients, 4.5%), and chordal elongation or rupture (3 patients, 3.4%). Median interval since previous repair was 4.0 (0.04-18.0) years for the technique-related failure group, and 9.7 (0.21-35.6) years for valve-related failure group (P < 0.05). ConclusionTechnique-related factors are main causes of repair failure, which include leaflet suture dehiscence, edge-to-edge procedure, and leaflet thickening or retraction. Reoperation for technique-related failure needs to be adopted early.

Objective To discuss the resection extent of primary surgery for papillary thyroid carcinoma （PTC） based on the analysis of the remaining thyroid gland residue and lymph nodes metastasis. Methods The clinical data of 163 patients with PTC received reoperation from January 2009 to September 2011 in our hospital were analyzed retrospectively. Results There were 24 males and 139 females in these patients. The age was 10-75 years old with （38.22±14.57） years old. Among 131 patients received residual thyroid thyroidectomy，88 patients were below 45 years old，and the cancer residual rate was 60.23% （53/88）；the others were over 45 years old，and the cancer residual rate was 76.74% （33/43），which was no significant difference （P?=?0.062）.The lymph nodes metastasis rate was 77.14% （81/105） in the patients below 45 years old and 81.13%?（43/53） in the patients over 45 years old among 158 patients received cervical lymph nodes dissection，which was no significant difference （P?=?0.958）.The cancer residual rate was 74.36%?（58/78），53.66%?（22/41），50.00%?（6/12），and 0 （0/32） in the patients with the tissue less than one lobe resection，lateral lobe （isthmus） resection，lateral lobe plus opposite side subtotal resection，total or subtotal resection，respectively. The total cancer residual rate was 65.65% （86/131） and the bilateral cancer residual rate was 52.76%?（86/163） after reoperation.79.75%?（130/163） of the patients didn’t received lymph nodes dissection in the primary surgery. The lymph nodes metastasis rate was 71.21%?（94/132） and 80.58% （83/103） in the reoperation patients received central region lymph nodes dissection and cervical lateral lymph nodes dissection, respectively. Conclusions Multifocus is an obvious character of PTC. Patients over 45 years old have more opportunities of tumor residual than that of the youngers （below 45 years old），but the result was no statistic value. For the most patients with PTC，a smaller resection extent suggests a larger risk for cancer residual，and total thyroidectomy or subtotal thyroidectomy leads to the least possibility for the risk. Cervical lymph node is a major type for its metastasis. Proper lymph nodes dissection is an essential way to reduce recurrence and reoperation. The Revised American Thyroid Association Management Guidelines for Patients with Thyroid Nodules and Differentiated Thyroid Cancer （2009） could be a best choice for therapy of PTC. And it is proposed to take central region lymph nodes dissection during primary surgery.
Objective To analyze clinical features of reoperation patients with differentiated thyroid cancer, and to explore reason, surgical pattern and therapeutic effectiveness of reoperation. Method The clinical data of 80 patients with differentiated thyroid cancer underwent reoperation from January 2012 to June 2016 in Peking Union Medical College Hospital were analyzed retrospectively. Results ① Eighty (5.37%) patients with differentiated thyroid cancer underwent reoperation were identified from a total of 1 491 patients with thyroid cancer in our treatment team. Twenty-seven cases were males, 53 cases were females. The male to female ratio was 1∶1.96. The age was (44±13) years with a range from 14 to 66 years. The median time between reoperation and the first operation was 16.8 months with a range from 8 days to 17 years. ② Thirteen cases underwent reoperation because of uncertain frozen sections, and the reoperation style was residual lobectomy and selective lymph node dissection. Sixty-seven cases underwent reoperation because of local recurrence or metastasis, 15 of them accepted residual lobectomy and selective lymph node dissection while the other 52 accepted selective lymph node dissection. ③ The rate of residual in thyroid cancer confirmed by postoperative pathology was 18.8% (15/80). The rate of cervical lymph node metastasis was 63.8% (51/80). The temporary laryngeal recurrent nerve injury occured in 6 cases, the temporary hypocalcemia occured in 9 cases, and the lymphorrhagia occured in 2 cases. ④ The hospitalization time was (6.50±0.97) d with a range from 3 to10 d, the time of drainage tube remove was (2.41 ±0.95) d with a range from 2 to 7 d. Seventy-three cases were followed up from 3 to 58 months with (32±18) months, 4 of them underwent operation once again because of local recurrence, no distant metastasis or death happened. ⑤ The proportion of male patients in reoperation patients was significantly higher than that of the first operation patients (P<0.05). The proportion of patients aged <45 years, the average hospitalization time, the average time of drainage tube remove, and the postoperative complications rate had no significant differences between the patients with the first operation and the patients with reoperation (P>0.05). Conclusions For reoperation patients, proportion of male patients is higher. Reoperation is proper treatment for patients with residual lobe or local recurrence or metastasis for differentiated thyroid cancer. Serious complications could be avoided by suitable surgical pattern and careful dissection during operation. Residual lobectomy and selective lymph node dissection are suggested for reoperation.
ObjectiveTo investigate the reason, prevention, and treatment measures of gastrointestinal unplanned reoperation. MethodsClinical data of 21 patients who carried out gastrointestinal unplanned reoperation for various reasons from Jun. 2012 to Jun. 2013 in our hospital were retrospectively analyzed. ResultsTwenty-one of 2 492 patients with gastrointestinal tract surgery carried out gastrointestinal unplanned reoperation, and the incidence of reoperation was 0.8%. The causes of reoperation were intra-abdominal hemorrhage in 10 cases, gastrointestinal fistula in 7 cases, inflammatory intestinal obstruction with peritonitis in 1 case, and incision dehiscence in 3 cases. After undergoing suture hemostasis, colostomy, anastomotic fistula repair, debridement, and suture,20 cases were cured or improved, and 1 case died. The median of hospitalization expense was 76 000 yuan(46 000-116 000 yuan), and the median of hospital stay was 25-day(16-49 days). ConclusionsGastrointestinal unplanned reoperation can cause more serious economic and emotional burden to patients, standardizing surgical procedure and enhancing perioperative monitoring can reduce the incidence of unplanned reoperation. In addition, grasp legitimately the indications of reoperation, implement timely, and effective reoperation can avoid further deterioration of the disease.
