ObjectiveTo investigate the short-term effectiveness of minimally invasive percutaneous plate osteosynthesis (MIPPO) in treatment of anterior pelvic ring fractures. MethodsBetween January 2012 and October 2013, 16 patients with anterior pelvic ring fractures were treated with MIPPO. There were 10 males and 6 females at the age of 20-63 years (mean, 41 years). The causes of injury were traffic accident in 9 cases and falling from height in 7 cases. The duration of injury to admission was 2 hours to 5 days (mean, 1 day). According to Tile classification, 8 cases were rated as type B2, 4 cases as type B3, 2 cases as type C1, and 2 cases as type C2. Of them, 2 cases had iliac wing fracture, and 4 cases had pelvic posterior ring fracture. The time from admission to operation was 3-12 days (mean, 6 days). ResultsThe bleeding volume was 60-120 mL (mean, 70 mL). All wounds healed by first intention. No postoperative complication of deep venous thrombosis or long-term continuous pain occurred. All cases were followed up 5-27 months (mean, 11.5 months). No clinical manifestation of lateral femoral cutaneous nerve injury or spermatic cord injury was found, and cremasteric reflex existed in males. All cases obtained bony union, and the healing time was 12-16 weeks (mean, 13 weeks). During the follow-up period, no loss of fracture reduction and no internal fixation loosening or broken were observed. According to Matta radiological evaluation criterion, 16 cases had anatomical reduction, and 3 cases had satisfactory reduction; according to Majeed scoring system of pelvic fracture, the results were excellent in 12 cases and good in 4 cases. ConclusionMIPPO for treatment of anterior pelvic ring fractures has the advantages of less intraoperative blood loss, few soft tissue complications, and low infection rate, and can get satisfactory short-term effectiveness.
Objective To investigate the short-term effectiveness of reconstruction plate internal fixation via improved Stoppa approach combined with iliac fossa approach and Kocher-Langenbeck approach for complex acetabular fractures. Methods Between January 2015 and January 2020, 30 patients with complex acetabular fractures were treated with reconstruction plate internal fixation via improved Stoppa approach combined with iliac fossa approach and Kocher-Langenbeck approach. There were 20 males and 10 females with an average age of 52.1 years (range, 25-71 years). The cause of injury included traffic accident in 17 cases and falling from height in 13 cases. Among them, 14 cases were left acetabular fractures and 16 cases were right acetabular fractures. According to Letournel classification, there were 16 cases of double column fractures, 2 cases of transverse fracture with posterior wall fracture, 4 cases of anterior column and posterior hemi-transverse fractures, 8 cases of T-shaped fracture. The displacement distance of fracture ranged from 6 to 30 mm (mean, 11.6 mm). The time from injury to operation was 6-14 days (mean, 8.7 days). Results The operation time was 2.0-4.5 hours (mean, 3.0 hours). The intraoperative blood loss was 200-800 mL (mean, 450.0 mL). All patients were treated with autologous blood transfusion during operation. All incisions healed by first intention after operation, and no infection occurred. All patients were followed up 12-15 months (mean, 13.4 months). The drainage tube was removed at 2-3 days after operation. After extubation, X-ray film and three-dimensional CT were performed to recheck the fracture reduction. According to Matta score system, 20 cases were excellent, 5 were good, and 5 were poor, the excellent and good rate was 83.3%. All fractures healed with the healing time of 16-25 weeks (mean, 17.7 weeks). According to Merle d’Aubigne-Postel score system, the hip function at 1 year after operation was rated as excellent in 18 cases, good in 6 cases, and fair in 6 cases, and the excellent and good rate was 80.0%. Two cases suffered from sciatic nerve injury due to traction during operation, 7 cases had heterotopic ossification, 2 cases had traumatic hip arthritis, and no other complications occurred. Conclusion For complex acetabular fractures, the reconstruction plate internal fixation via improved Stoppa approach combined with iliac fossa approach and Kocher-Langenbeck approach can obtain good short-term effectiveness with good reduction and hip joint function, and less complications.
ObjectiveTo investigate the feasibil ity and short-term effectiveness of percutaneous endoscopic spine surgery for treatment of lumbar disc herniation with posterior ring apophysis separation. MethodsBetween July 2008 and January 2013, 57 patients with lumbar disc herniation and posterior ring apophysis separation were treated. There were 39 males and 18 females, aged from 13 to 46 years (mean, 26.7 years). Of 57 cases, 29 had a clear trauma history. All patients had single segmental unilateral lumbar disc herniation, and the location was at L4, 5 in 22 cases and at L5, S1 in 35 cases; there were 25 cases of lateral bone fragments and 32 cases of central cortical and cancellous fragments. While fracture located at posterior inferior edge of the vertebrae at L4 level in 9 cases and at L5 level in 8 cases, at posterior superior edge at L5 level in 13 cases and in S1 level in 27 cases. Percutaneous endoscopic surgeries were performed via interlaminar or transforaminal approach from unilaterally symptomatic side for discectomy of lumbar disc herniation and partial or complete resection of free bone fragments. ResultsAccurate positioning was obtained in all patients during operation, and no complication of nerve root injury, hematoma formation, or dural tear occurred. The operation time was 20-85 minutes; the intraoperative fluoroscopy times were 2-15 times, and the blood loss was 3-10 mL. Postoperative radiographic examination showed that bone fragment was not removed in 16 cases, was partly removed in 32 cases, and was completely removed in 9 cases. Disc was completely removed. All patients were followed up 10-64 months (median, 16 months). According to modified Macnab criteria for the evaluation of effectiveness, the results were excellent in 48 cases, good in 6 cases, and fair in 3 cases, and the excellent and good rate was 94.7%. ConclusionPercutaneous endoscopic spine surgery through unilaterally symptomatic approach has advantages of small tissue damage and lumbar structure damage, less bleeding, and shorter recovery time. It has a good short-term effectiveness, but long-term effectiveness need further follow-up.
Objective To discuss whether age has an influence on short-term effect of intersphincteric resection (ISR) for elderly (≥75 years old) patients with ultra-low rectal or canal cancer or not. Methods From February 2016 to February 2017, 196 patients with ultra-low rectal or canal cancer received ISR in the Gastrointestinal Surgery Center of West China Hospital were eligible to include in this study, then they were divided into ≥75 years old group and <75 years old group according to the patients’ age. The intraoperative index, postoperative index, and complications rate were compared between these two groups. Results There were 113 cases in the ≥75 years old group, 83 cases in the <75 years old group, the baselines such as the gender composition, body mass index, tumor histology type, differentiation degree, tumor size, and distance from the anal margin had no significant differences ( P>0.05), but the preoperative anaesthetized ASA grade, proportions of pulmonary insufficiency, hypoproteinemia, anemia, hypertension, diabetes, and cardiac insufficiency of the ≥75 years old group were significantly higher than those of the <75 years old group (P<0.05). The operative time, intraoperative bleeding, and total complications rate had no differences between these two groups (P>0.05), the first exhaust time, the first eating time, the first defecation time, the first ambulation time, and hospitalization time of the ≥75 years old group were significantly longer than those of the <75 years old group (P=0.023, 0.037, 0.019, 0.020, and 0.012, respectively). There were no significant differences in the incidences of the anastomotic leakage, perianal infection, intestinal obstruction, and wound infection between these two groups (P>0.05). All the 196 patients were followed-up with an average follow-up of 7 months, there were 4 cases of recurrent patients, of which 3 were in the ≥75 years old group and 1 in the <75 years old group; there were 3 cases of death, of which 2 were in the ≥75 years old group and 1 in the <75 years old group. Conclusions Short-term recovery of elderly patients with ultra-low rectal or canal cancer is slower than younger patients because of poor preoperative conditions. ISR surgery is still safe and effective for elderly patients with ultra-low rectal or canal cancer and postoperative complications rate has no obvious increase, but it needs a surgeon’s skilled operation technology and multi-disciplinary team cooperation.
ObjectiveTo evaluate the safety and short-term outcome of laparoscopic total mesorectal excision (TME) for the middle-lower rectal cancer in municipal hospital.MethodsThe pathological data of 94 patients with middle-lower rectal cancer (49 cases underwent laparoscopic TME, while 45 cases received open TME), who treated in The First People’s Hospital of Ziyang from Jan. 2015 to Jun. 2017, were retrospectively collected and analyzed.ResultsTwo patients (4.1%) in laparoscopy group were converted to open surgery. Compared with the laparotomy group, the laparoscopic group had significantly less volume of intraoperative bleeding, shorter abdominal incision, earlier time to the first flatus and liquid diet, and lower rate of 30-day postoperative complication (P<0.05), but had longer operative time (P=0.033). While there were no significant difference on postoperative stay, the specimen length, distal margin, and number of harvested lymph nodes between the 2 groups (P>0.05).ConclusionLaparoscopic TME is a feasible, safe, and minimally invasive technique for middle-lower rectal cancer, and produce more favourable short-term outcome than open surgery in municipal hospital.
