Perioperative morbidity of different operative approaches in early cervical carcinoma: a systematic review and meta-analysis comparing minimally invasive versus open radical hysterectomy.

PURPOSE: Radical hysterectomy and pelvic lymphadenectomy is the standard treatment for early cervical cancer. Studies have shown superior oncological outcome for open versus minimal invasive surgery, but peri- and postoperative complication rates were shown vice versa. This meta-analysis evaluates the peri- and postoperative morbidities and complications of robotic and laparoscopic radical hysterectomy compared to open surgery. METHODS: Embase and Ovid-Medline databases were systematically searched in June 2020 for studies comparing robotic, laparoscopic and open radical hysterectomy. There was no limitation in publication year. Inclusion criteria were set analogue to the LACC trial. Subgroup analyses were performed regarding the operative technique, the study design and the date of publication for the endpoints intra- and postoperative morbidity, estimated blood loss, hospital stay and operation time. RESULTS: 27 studies fulfilled the inclusion criteria. Five prospective, randomized-control trials were included. Meta-analysis showed no significant difference between robotic radical hysterectomy (RH) and laparoscopic hysterectomy (LH) concerning intra- and perioperative complications. Operation time was longer in both RH (mean difference 44.79 min [95% CI 38.16; 51.42]), and LH (mean difference 20.96 min; [95% CI - 1.30; 43.22]) than in open hysterectomy (AH) but did not lead to a rise of intra- and postoperative complications. Intraoperative morbidity was lower in LH than in AH (RR 0.90 [0.80; 1.02]) as well as in RH compared to AH (0.54 [0.33; 0.88]). Intraoperative morbidity showed no difference between LH and RH (RR 1.29 [0.23; 7.29]). Postoperative morbidity was not different in any approach. Estimated blood loss was lower in both LH (mean difference - 114.34 [- 122.97; - 105.71]) and RH (mean difference - 287.14 [- 392.99; - 181.28]) compared to AH, respectively. Duration of hospital stay was shorter for LH (mean difference - 3.06 [- 3.28; - 2.83]) and RH (mean difference - 3.77 [- 5.10; - 2.44]) compared to AH. CONCLUSION: Minimally invasive radical hysterectomy appears to be associated with reduced intraoperative morbidity and blood loss and improved reconvalescence after surgery. Besides oncological and surgical factors these results should be considered when counseling patients for radical hysterectomy and underscore the need for new randomized trials.

Protective operative techniques in radical hysterectomy in early cervical carcinoma and their influence on disease-free and overall survival: a systematic review and meta-analysis of risk groups.

PURPOSE: Radical hysterectomy with pelvic lymphadenectomy presents the standard treatment for early cervical cancer. Recently, studies have shown a superior oncological outcome for open versus minimal invasive surgery, however, the reasons remain to be speculated. This meta-analysis evaluates the outcomes of robotic and laparoscopic hysterectomy compared to open hysterectomy. Risk groups including the use of uterine manipulators or colpotomy were created. METHODS: Ovid-Medline and Embase databases were systematically searched in June 2020. No limitation in date of publication or country was made. Subgroup analyses were performed regarding the surgical approach and the endpoints OS and DFS. RESULTS: 30 studies fulfilled the inclusion criteria. Five prospective, randomized-control trials were included. Patients were analyzed concerning the surgical approach [open surgery (AH), laparoscopic surgery (LH), robotic surgery (RH)]. Additionally, three subgroups were created from the LH group: the LH high-risk group (manipulator), intermediate-risk group (no manipulator, intracorporal colpotomy) and LH low-risk group (no manipulator, vaginal colpotomy). Regarding OS, the meta-analysis showed inferiority of LH in total over AH (0.97 [0.96; 0.98]). The OS was significantly higher in LH low risk (0.96 [0.94; 0.98) compared to LH intermediate risk (0.93 [0.91; 0.94]). OS rates were comparable in AH and LH Low-risk group. DFS was higher in the AH group compared to the LH group in general (0.92 [95%-CI 0.88; 0.95] vs. 0.87 [0.82; 0.91]), whereas the application of protective measures (no uterine manipulator in combination with vaginal colpotomy) was associated with increased DFS in laparoscopy (0.91 [0.91; 0.95]). CONCLUSION: DFS and OS in laparoscopy appear to be depending on surgical technique. Protective operating techniques in laparoscopy result in improved minimal invasive survival.

Heel anatomy for retrograde tibiotalocalcaneal roddings: a roentgenographic and anatomic analysis.

There is an increased interest in load-sharing devices for tibiotalocalcaneal arthrodesis. Although the neurovascular anatomy of the heel has been well described, the purpose of this study is to consider heel anatomy as it relates to plantar heel incisions and to well-defined fluoroscopic landmarks to prevent complications during these procedures. Twenty lateral radiographs of normal feet while standing were evaluated by two observers. The distance from the calcaneocuboid (CC) joint to a line parallel to the center of the intramedullary canal of the tibia was calculated. In the second part of the study, 14 dissections of the arterial and neural anatomy were performed. The distances from the CC joint to structures crossing the heel proximal to the CC joint were studied. In the 20 standing radiographs, the mean distance from the CC joint to the middle of the intramedullary canal of the tibia was 2.1 cm (standard deviation, 0.55 cm). In the dissections, the only artery or nerve found to cross the plantar surface proximal to the CC joint was the nerve to the abductor digiti quinti (NAbDQ). The mean distance from the CC joint to the NAbDQ was 3.1 cm (standard deviation, 1.36 cm). Assuming reaming to 12 mm, NAbDQ would be at risk 42% of the time. We recommend careful dissection of the heel during retrograde roddings to avoid damage to NAbDQ and subsequent neurogenic heel pain.

Arthroscopic treatment of calcific tendinitis of the shoulder.

The results of arthroscopic treatment of chronic resistant calcific tendinitis of the shoulder in twenty-three patients were evaluated. Each patient had greater than 1 year of unsuccessful nonoperative management prior to arthroscopic surgery. The average age was 49 years (range 33-60) and average follow up was 26 months (range 12-47). Subacromial bursectomy was performed in all patients. Based on follow-up radiographs, thirteen patients had partial calcium removal while nine had complete removal of calcium. Results were graded as good in eleven patients (50%) with full motion and complete pain relief, satisfactory in nine (41%) patients with full motion and occasional episodes of pain, and unsatisfactory in two (9%) patients with persistent pain. Arthroscopic calcium removal and subacromial bursectomy are reasonable alternatives in the treatment of chronic calcific tendinitis resistant to conservative treatment.

MR imaging of the knee: clarification of its role.

In an attempt to further delineate the role of magnetic resonance (MR) imaging in evaluating knee pathology, a retrospective study of 60 patients who underwent MR scanning before arthroscopy was undertaken. For medial meniscus tears, the sensitivity of MR imaging was 97% whereas its specificity was 77%. For lateral meniscus tears, MR imaging was 90% sensitive and 87% specific. The positive predictive value of MR imaging was 85% for medial meniscus tears and only 79% for lateral meniscus tears. The negative predictive value was 95% for the medial meniscus and 94% for the lateral meniscus. MR imaging had an accuracy of 93% in assessing anterior cruciate ligament pathology also. These results begin to clarify the role of MR imaging in evaluating intraarticular knee pathology. Grade III signals represented tears at arthroscopy more than 90% of the time. False-positive results occurred more frequently than false negative results did. The high negative predictive value of MR imaging indicates that with a negative MR image, the orthopaedist can reliably conclude that no meniscal pathology is present. MR imaging is a useful diagnostic tool; however, it should be used selectively and in conjunction with the clinical examination in evaluating internal derangements of the knee.
