Case Report: 21 Cases of Umbilical Hernia Repair Using a Laparoscopic Cephalic Approach Plus a Posterior Sheath and Extraperitoneal Approach

Purpose: In this study, a novel surgical technique was developed for umbilical hernias, in which a laparoscopic cephalic approach plus a posterior sheath and an extraperitoneal approach was employed. The aim of this study was to determine the results of this new technique.Methods: From 2019 to 2020, 21 patients (81.8% men) with an umbilical hernia underwent a laparoscopic cephalic approach plus a posterior sheath and extraperitoneal approach, performed by two surgeons specializing in abdominal wall surgery, in two academic hospitals. Intraoperative and postoperative complications, operation time, blood loss, and hernia recurrence were assessed.Results: Twenty-one cases of umbilical hernia were successfully completed. The size of the hernia ring was 1.5–3 cm2, with an average of 2.39 ± 0.47 cm2. The operation time was 120–240 min (average, 177.3 ± 42.15 min), and the blood loss volume was 30–40 ml (average, 33.73 ± 3.55 ml). The mean follow-up period was 6 months, and there were no short-term complications and no cases of recurrence.Conclusion: A laparoscopic cephalic approach plus a posterior sheath and extraperitoneal approach is a safe alternative for the repair of an umbilical hernia. The intraoperative complication rate was low.

Abstract Background The area which located at the medial pedicle, posterior vertebral body and ventral hemilamina is defined as the hidden zone. Surgical management of hidden zone lumbar disc herniation (HZLDH) is technically challenging due to its difficult surgical exposure. The conventional interlaminar approach harbors the potential risk of post-surgical instability, while other approaches consist of complicated procedures with a steep learning curve and prolonged operation time. Objective To introduce microscopic extra-laminar sequestrectomy (MELS) technique for treatment of hidden zone lumbar disc herniation and present clinical outcomes. Methods Between Jan 2016 to Jan 2018, twenty one patients (13 males) with HZLDH were enrolled in this study. All patients underwent MELS (19 patients underwent sequestrectomy only, 2 patients underwent an additional inferior discectomy). The nerve root and fragment were visually exposed using MELS. The operation duration, blood loss, intra- and postoperative complications, and recurrences were recorded. The Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and the modified MacNab criteria were used to evaluate clinical outcomes. Postoperative stability was evaluated both radiologically and clinically. Results The mean follow-up period was 20.95 ± 2.09 (18–24) months. The mean operation time was 32.43 ± 7.19 min and the mean blood loss was 25.52 ± 5.37 ml. All patients showed complete neurological symptom relief after surgery. The VAS and ODI score were significantly improved at the final follow-up compared to those before operation (7.88 ± 0.70 vs 0.10 ± 0.30, 59.24 ± 10.83 vs 11.29 ± 3.59, respectively, p < 0.05). Seventeen patients (81%) obtained an “excellent” outcome and the remaining four (19%) patients obtained a “good” outcome based the MacNab criteria. One patient suffered reherniation at the same level one year after the initial surgery and underwent a transforaminal endoscopic discectomy. No major complications and postoperative instability were observed. Conclusions Our observation suggest that MELS is safe and effective in the management of HZLDH. Due to its relative simplicity, it comprises a flat surgical learning curve and shorter operation duration, and overall results in reduced disturbance to lumbar stability.

Introduction: Irreducible atlantoaxial dislocation (IAAD) has been challenging for spine surgeons. Various methods have been used to treat IAAD, but no consensus has been reached. This study aimed to retrospectively analyze the efficacy of anterior submandibular retropharyngeal release and posterior reduction and fixation for IAAD. Methods: From March 2007 to May 2015, 13 patients diagnosed with IAAD underwent anterior submandibular retropharyngeal release and sequential posterior reduction and fixation. The operation time, blood loss, postoperative complications, and Japanese Orthopaedic Association (JOA) scores were retrospectively recorded. Results: The surgeries were accomplished successfully. The mean operative time was about 3.8 h. The mean estimated blood loss was about 130 mL. The patients experienced postoperative pharyngeal pain. Only one patient had a vague voice and increased oral discharge postoperatively. At the final follow-up, JOA scores had significantly increased ( p < 0.05), and all the patients had solid bony fusion. Conclusion: The present study reinforces the efficacy and safety of anterior submandibular retropharyngeal release and posterior reduction and fixation for IAAD. It can achieve satisfactory clinical outcomes and is safe for experienced spine surgeons.

Abstract Background Pubic defects resulting from type III hemipelvectomy are commonly not reconstructed due to the need to preserve the weight-bearing axis. However, the opening of the anterior pelvic ring will inevitably lead to increased pelvic instability. To improve long-term pelvic stability, three-dimensional (3D)-printed customized prostheses were designed to reconstruct pubic defects. This study presents and evaluates the short-term clinical outcomes and complications from the use of this construct. Methods Five patients who underwent type III hemipelvectomy and 3D-printed customized prosthesis reconstruction at our institution between 2017 and 2019 were retrospectively analysed. Operation time and blood loss during the operation were recorded. Local and functional recovery was assessed. Prosthetic position and osseointegration were evaluated. Oncology results and complications were recorded. Results The prostheses consisted of three with stems and two without. The mean follow-up time was 23.6 months. At the last follow-up, all five patients were alive with no evidence of disease. No deep infections or local recurrence had occurred. The mean blood loss and mean intraoperative time were 1680 ml and 294 min, respectively. The mean functional MSTS score at the final follow-up was 29.8. Fretting wear around the prosthetic stem was found in 3 patients, while bone wear on the normal-side pubis was found in 2 patients. Osseointegration was observed in all patients. Conclusions 3D-printed customized prostheses for reconstructing pubic bone defects after type III hemipelvectomy showed acceptable early outcomes. The good outcomes were inseparable from the precision prosthesis design, strict surgical procedures, and sensible postoperative management.

Object The aim of this study was to evaluate after more than 5 years the outcome of surgical treatment for flexible idiopathic scoliosis using skipped pedicle screw fixation. Methods For patients with spine curves < 90° and flexibility > 20%, pedicle screws had been inserted into every other segment on the corrective side and 2–4 screws per curve had been inserted on the supportive side. The authors analyzed the results in 57 patients, including the correction rate of coronal curvature and rotational deformity, correction loss, sagittal balance, complications, blood loss, operation time, and implant costs. Results The mean Cobb angle was 54° preoperatively and 17° immediately after surgery (69% correction). At the last follow-up, the mean Cobb angle was 18° (2% correction loss). Rotation of the apical vertebra was corrected by 50% on average and showed only a 6% correction loss at the last follow-up. None of the patients had problems in maintaining sagittal balance. An adding-on phenomenon was detected in 4 patients (7%). Twelve of 14 patients with coronal decompensation showed improvement after surgery, whereas postoperative decompensation developed in 3 patients. Four patients had implant failures, and 4 had postoperative infections. The mean blood loss during surgery was 832 ml, and the mean operation time was 167 minutes. Compared with conventional methods, the authors' method used up to 48% fewer screws. Conclusions Skipped pedicle screw fixation of flexible idiopathic scoliosis showed satisfactory results. This method has several advantages, including reduced blood loss, shorter operation time, and reduced cost.

Background. The Mirizzi syndrome (MS) is a rare complication of cholecystolithiasis that is often accompanied by severe inflammation and fibrosis around Calot’s triangle. It is difficult to treat Type 2 MS surgically, and the treatment for this condition has not yet been standardized. The data on operative management are limited. The study aimed to review our institutional clinical experience regarding surgery and provide recommendations for treating Type 2 MS. Methods: We conducted a retrospective study on 6 patients with MS who were surgically treated at our institution between January 2010 and December 2019. The classification of MS by McSherry CK, Ferstenberg H, Virshup M. The Mirizzi syndrome: Suggested classification and surgical therapy. Surg Gastroenterol. 1982;1:219-225 was used. Mucosal approach was used to treat Type 2 MS. The parameters for comparison included patient demographics, operative procedures, operation time, blood loss, length of hospital stay, complications, and follow-up. Results: There were 23 patients with MS among 10 386 cholecystectomies in our area. Six patients with Type 2 MS had successful surgery, and the mucosal approach was used. The average operative time was 253.3 ± 32.5 minutes. The average blood loss was 70.0 ± 14.1 mL. The mean postoperative hospital stay was 9.5 ± 3.9 days. There was no postoperative mortality. The most frequent postoperative complications were bile leakage (16.7%), and postoperative intra-abdominal collection (16.7%). The mean postoperative follow-up was 10 months, and all patients are asymptomatic. The mucosal approach may decrease the risk of bile duct injury, biliary tract infection, and blood loss more than other surgical approaches. Conclusion: This study demonstrates that the mucosal approach is an effective surgical procedure for Type 2 MS.

Abstract Background To explore the therapeutic effect of early surgical intervention for active thoracic spinal tuberculosis (TB) patients with paraparesis and paraplegia. Methods Data on 118 active thoracic spinal TB patients with paraparesis and paraplegia who had undergone surgery at an early stage (within three weeks of paraparesis and paraplegia) from January 2008 to December 2014 were retrospectively analyzed. The operation duration, blood loss, perioperative complication rate, VAS score, ASIA grade and NASCIS score of neurological status rating, Erythrocyte Sedimentation Rate (ESR), C-reactive protein (CRP), kyphotic Cobb’s angle, and duration of bone graft fusion were analyzed to evaluate the therapeutic effects of surgery. Results The mean operating time was 194.2 minutes, and the mean blood loss was 871.2 ml. The perioperative complication rate was 5.9 %. The mean preoperative VAS score was 5.3, which significantly decreased to 3.2 after the operation and continued decreasing to 1.1 at follow up (P<0.05). All cases achieved an increase of at least one ASIA grade after operation. The rate of full neurological recovery for paraplegia (ASIA grade A and B) was 18.0 % and was significantly lower than the rate (100 %) for paraparesis (ASIA grade C and D) (P<0.05). On the NASCIS scale, the difference in the neurological improvement rate between paraplegia (22.2 % ± 14.1 % in sensation and 52.2 % ± 25.8 % in movement) and paraparesis (26.7 % ± 7.5 % in sensation and 59.4 % ± 7.3 % in movement) was remarkable (P<0.05). Mean preoperative ESR and CRP were 73.1 mm /h and 82.4 mg/L, respectively, which showed a significant increase after operation (P>0.05), then gradually decreased to 11.5 ± 1.8 mm/h and 2.6 ± 0.82 mg/L, respectively, at final follow up (P<0.05). The mean preoperative kyphotic Cobb’s angle was 21.9º, which significantly decreased to 6.5º after operation (P<0.05) while kyphotic correction was not lost during follow up (P>0.05). The mean duration of bone graft fusion was 8.6 ± 1.3 months. Conclusions Early surgical intervention may be beneficial for active thoracic spinal TB patients with paraparesis and paraplegia, with surgical intervention being more beneficial for recovery from paraparesis than paraplegia.

Introduction: We report our experience with laparoscopic management of ureteropelvic junction obstruction in horseshoe kidneys.Methods: Between February 2004 and March 2014, 15 patients with horseshoe kidneys and symptomatic ureteropelvic junction obstruction underwent laparoscopic management at our national referral centre. Depending on the anatomy and presence of obtrusive vessels or isthmus, we performed either dismembered, Scardino or Foley YV pyeloplasty, or Hellstrom vessel transposition. Patients were initially evaluated by ultrasonography, then diuretic scintiscan at 4 to 6 months, and followed by yearly clinical and sonographic exams.Results: This study included 11 male and 4 female patients between the ages of 4 to 51 year (average 17.7). The left kidney was involved in 12 patients (80%). Operation time was 129 minutes (range: 90–186), and patients were discharged within 2.8 days (range: 1–6). Although 8 (53.3%) patients had crossing vessels, of which 6 required transposing, the Hellstrom technique was solely used in 3 cases, of which notably 1 case failed to resolve and required laparoscopic Hynes within the next year. Eight cases underwent dismembered pyeloplasty, 2 Foley YV, 1 Scardino flap and 1 required isthmectomy and vessel suspension. At the mean follow-up of 60 (range: 18–120) months, the overall success rate was 93.3%.Conclusions: To our knowledge, this represents the largest report on laparoscopic pyeloplasty for horseshoe kidneys, providing the longest follow-up. Our findings confirm prior reports supporting laparoscopy and furthermore show that despite the prevalence of crossing vessels, transposition alone is seldom sufficient.

The Mean

BACKGROUND An ideal surgery to remove hypertrophied adenoid mass should be safe, with less bleeding and operation time along with post-operative improvement in the eustachian tubal ventilation and normal respiration. It should also have low morbidity and mortality. Among the various methods described for its removal, the two commonly used methods are conventional cold curettage method and coblation technique. The purpose of this study was to collate the safety and efficacy of endoscopic coblation adenoidectomy with the conventional curettage adenoidectomy. METHODS A prospective comparative study with fifty patients was studied who underwent adenoidectomy. Twenty five patients underwent endoscopy assisted coblation adenoidectomy and twenty five patients underwent regular adenoidectomy by curettage. RESULTS Patients who underwent coblation adenoidectomy showed better results during follow up in terms of completeness of removal. 80 % of children undergoing regular adenoidectomy by curettage method showed remnant adenoid tissue in the nasopharynx at the end of the procedure. But it was 6 % among the children undergoing endoscopic assisted coblation adenoidectomy. The mean duration of operation was higher for endoscopic assisted coblation adenoidectomy which was significant statistically. The mean blood loss was 30.36 ml in regular curettage adenoidectomy; 10.6 ml with endoscopic coblation adenoidectomy. The grading of pain was significantly lower in endoscopic assisted coblation adenoidectomy. There was no significant difference between two groups in terms of eustachian tube function after surgery. CONCLUSIONS Coblation adenoidectomy has significant advantages over conventional adenoidectomy in terms of completeness of removal, reduced blood loss, and lower post-operative pain grade.
