Intraoperative complications during radical cystectomy: a detailed analysis of intraoperative vascular injuries.

The standardized procedure, technical key points and latest progress of laparoscopic lateral suspension surgery.

Pelvic organ prolapse (POP) is a common condition that can affect up to 30% of women over the age of 50. For a long time, open abdominal and laparoscopic sacrocolpopexy (LSCP) have been considered the gold standard in the treatment of apical pelvic organ prolapse (POP). Promontory dissection may expose patients to potential life-threatening intraoperative vascular injuries, as well as damage to sacral roots or the hypogastric nerve. Laparoscopic lateral suspension could be considered as an alternative to LSCP in the treatment of POP due to its favorable objective and subjective outcomes. The aim of this article is to demonstrate a step-by-step approach to laparoscopic lateral suspension for POP with the goal of standardizing this procedure. Technical key points and the latest progress are summarized to provide a reference for subsequent gynecological and urological surgeons. According to our surgical experience of our hospital, demonstrate a step-by-step approach and highlight technical key points for laparoscopic lateral suspension for POP with the aim of standardizing this procedure. LLS with mesh is a safe alternative to laparoscopic sacropexy and is very well suited for uterine-preserving POP surgery. Nevertheless, this novel procedure lacks standardization. Standardization of procedures is necessary to reduce failure rates, generate impactful research data, and enhance patient safety. This article contributes to the standardization of this procedure, and we believe our article will be useful in assisting future gynecological and urological surgeons in performing this procedure.

A novel surgical approach using the "lateral corridor" for minimally invasive oblique lumbar interbody fusion at L5-S1: a clinical series and technical note.

The minimally invasive oblique lumbar interbody fusion (MI-OLIF) L5-S1 was introduced to overcome the limitations of conventional fusion techniques, however, MI-OLIF is not possible using the standard method due to vascular structures in some cases. We aimed to introduce the "lateral corridor" and report the details of the surgical technique with a clinical case series. We utilized the lateral access route of the left common iliac vein and named it the "lateral corridor", to distinguish the technique from the standard technique (central corridor). The type and frequency of branch vessels that required additional manipulations were reviewed, and the frequency of intraoperative vascular injury was investigated. Among the 107 patients who underwent MI-OLIF L5-S1, 26 patients (24.3%) who received the "lateral corridor" technique were included. Branch vessel ligation was required in 42.3% of the patients. The types of branch vessels that required ligation were seven cases (26.9%) of the iliolumbar vein (ILV) and six cases (23.1%) of ascending lumbar vein (ALV). The ILV and ALV were ligated in two cases. None of the patients developed intraoperative vascular injuries. We introduced the "lateral corridor" as an alternative approach for MI-OLIF L5-S1, implemented it in 24.3% of the patient cohort, and reported favorable outcomes devoid of vascular complications. The "lateral corridor" necessitated ligation of the ILV or ALV in 42.3% of cases. The "lateral corridor" approach appears to be a promising surgical technique, offering feasibility even in instances where the vascular anatomy precludes the employment of the conventional approach.

Risk factors for vascular injuries in anterior lumbar interbody fusion: a single-institution retrospective study.

Vascular injuries in anterior lumbar interbody fusion (ALIF) occur due to the vascular manipulation needed to achieve optimal disc space exposure. In this study, the authors aimed to evaluate intraoperative vascular injuries in patients undergoing single- and multilevel ALIF at a large tertiary academic center. Prospectively collected data specifically addressing postoperative complications in patients who underwent ALIF by neurosurgery spine faculty working with a specialized vascular surgeon were retrospectively reviewed. Demographic characteristics and intraoperative data were collected. Patients were split into vascular injury and non-vascular injury groups. Outcome comparisons were conducted using the chi-square exact and Wilcoxon rank-sum tests for categorical and continuous data, respectively. Logistic regression was used to investigate associations with vascular injury, with univariate analysis first conducted to identify candidate associations. Based on these results, variables demonstrating a between-groups test statistic of p < 0.10 were included in the multivariate analysis to determine the independent predictors of vascular injuries. In total, 323 patients who underwent ALIF procedures were identified: 51% were male (n = 166) and 49% were female (n = 157). The mean age was 57.1 years, with 56% (n = 182) having undergone prior lumbar surgery. Vascular injuries were encountered intraoperatively in 7.1% (n = 23) of patients, and the majority (91% [n = 21]) involved the left common iliac vein. Patients with vascular injuries were statistically older (mean 63.6 vs 56.6 years), had greater incidence rates of coronary artery disease, opioid use, multilevel ALIF surgery involving the L2-3 level, and surgery involving multiple disc spaces, had more multilevel anterior instrumentation, and experienced greater blood loss during surgery and longer length of stay (all p < 0.05). Overall, there was 1 death (0.3%) secondary to aortic artery injury. Multivariate analysis identified opioid use, multilevel ALIF involving L2-3, and multiple interbodies as statistically independent predictors of vascular injury (all p < 0.05). Identifying patient risk factors can reduce the risk of vascular injuries in ALIF. Opioid use, multilevel ALIF involving L2-3, and multiple interbodies were independent predictors of vascular injuries in ALIF.

Treatment of stage Ⅱ-Ⅲ Kümmell disease with robot-assisted bone cement-augmented pedicle screw fixation

To evaluate the early clinical efficacy of robot-assisted percutaneous short-segment bone cement-augmented pedicle screw fixation in the treatment of stageⅡ-Ⅲ Kümmell disease. The clinical data of 20 patients with stageⅡ-Ⅲ Kümmell's disease who underwent robot-assisted percutaneous bone cement-augmented pedicle screw fixation between June 2017 and January 2021 were retrospectively analyzed. There were 4 males and 16 females, aged from 60 to 81 years old with an average age of (69.1±8.3) years. There were 9 cases of stageⅡand 11 cases of stage Ⅲ, all of which were single vertebral lesions, including 3 cases of T11, 5 cases of T12, 8 cases of L1, 3 cases of L2, and 1 case of L3. These patients did not exhibit symptoms of spinal cord injury. The operation time, intraoperative blood loss, and complications were recorded. The position of pedicle screws and the filling and leakage of bone cement in gaps were observed using postoperative CT 2D reconstruction. The data of the visual analogue scale (VAS), Oswestry disability index (ODI), kyphosis Cobb angle, wedge angle of the diseased vertebra, and anterior and posterior vertebral height on lateral radiographs were statistically analyzed preoperatively, 1 week postoperatively, and at the final follow-up. Twenty patients were followed up for 10 to 26 months, with an average follow-up of (16.0±5.1) months. All operations were successfully completed. The surgical duration ranged from 98 to 160 minutes, with an average of (122±24) minutes. The intraoperative blood loss ranged from 25 to 95 ml, with an average of (45±20) ml. There were no intraoperative vascular nerve injuries. A total of 120 screws were inserted in this group, including 111 screws at grade A and 9 screws at grade B according to the Gertzbein and Robbins scales. Postoperative CT indicated that the bone cement was well-filled in the diseased vertebra, and cement leakage occurred in 4 cases. Preoperative VAS and ODI were (6.05±0.18) points and (71.10±5.37)%, respectively, (2.05±0.14) points and (18.57±2.77)% at 1 week after operation, and (1.35±0.11) points and (15.71±2.12) % at final follow-up. There were significant differences between postoperative 1 week and preoperative, and between final follow-up and postoperative 1 week(P<0.01). Anterior and posterior vertebral height, kyphosis Cobb angle, and wedge angle of the diseased vertebra were(45.07±1.06)%, (82.02±2.11)%, (19.49±0.77) °, and (17.56±0.94) ° preoperatively, respectively, (77.00±0.99)%, (83.04±2.02)%, (7.34±0.56) °, and (6.15±0.52) ° at 1 week postoperatively, and (75.13±0.86)%, (82.39±0.45)%, (8.38±0.63) °, and (7.09±0.59) ° at the final follow-up. Robot-assisted percutaneous short-segment bone cement-augmented pedicle screw fixation demonstrates satisfactory short-term efficacy in treating stageⅡ-Ⅲ Kümmell's disease as an effective minimally invasive alternative. However, longer operation times and strict patient selection criteria are necessary, and long-term follow-up is required to determine its lasting effectiveness.

These include limited exposure due to the small field, inability to quickly expand the surgical field with retractors and additional personnel, inability manually palpate or apply manual pressure over a broad area, and reliance on a limited array of robotic instruments. Other challenges include the limited field of vision of the robotic camera, as well as reliance on insufflation to maintain adequate visualization. Consultant surgeons may not have significant experience with using the robot. These all can translate into longer operative times for repair of vascular injuries with resultant blood loss. We sought to share insights on how a robotic surgeon may handle repairing a vascular injury. METHODS: Three robotic multi- and single-port operative cases with vascular injuries were examined. Operative strategy was analyzed and discussed. RESULTS: A single-port robotic nephroureterctomy was done on a 68 year-old female with past history of endometrial cancer, hysterectomy with lymph node dissection, and radiation to the pelvis. A common iliac vein injury was incurred during dissection of the distal ureter and was repaired using robotic 4th arm to clamp the injured vessel, strategic use of ROSI suction, and non-absorbable 4-0 suture. A multi-port robotic radical prostatectomy was done on a 63 year-old male with history of Gleason 4+3 prostate cancer with inadvertent injury of the external iliac artery. A combination of robotic bulldog clamps, assistant suction and non-absorbable 4-0 suture was used to successfully repair the injury. Lastly, a multi-port robotic adrenalectomy was done for a 48 year-old female with a 6.5 cm adrenal mass with invasion into the IVC. Repair of the IVC was done with a combination of 4th arm and bulldog clamps, vessel loop traction, and non-absorbable 4-0 suture. CONCLUSIONS: Strategies to robotically repair inadvertent vascular injuries during urologic surgery require strategic use of the 4th robotic arm, assistant- or robotically-applied clamps, and assistant instruments to free up working arms. Non-absorbable suture should be readily available. Closure of large blood vessels require releasing clamps momentarily before closure to avoid air embolus. Maximal visualization can be achieved using the zoom features of the robotic camera and its ability to discriminate fine detail. Maintaining composure with frequent and adequate communication with anesthesia and intensive care teams is vital in safely managing vascular injuries.

Correlations Between Preoperative Radiographic Vascular Involvement of Abdominal/Pelvic Neuroblastomas on Computed Tomography and Intraoperative Vascular Injuries: Experience From a Tertiary Children's Hospital

This research examines the prevalence and occurrence of intraoperative vascular injuries in abdominal or pelvic neuroblastomas. It also investigates the correlations between preoperative radiographic vascular involvement on computed tomography (CT) and intraoperative vascular injuries in abdominal or pelvic neuroblastomas. This study enrolled 297 patients with abdominal or pelvic neuroblastomas. The relationships between neuroblastomas and adjacent arteries on preoperative CT were categorized as no contact, contact (less than 50% of vessel circumference involved), partial encasement (less than 100% of vessel circumference involved), and total encasement (100% of vessel circumference involved). Similarly, the relationships between neuroblastomas and adjacent veins on preoperative CT were categorized as no compression, flattened with a visible lumen, and flattened with an invisible lumen. Furthermore, the correlations between preoperative radiographic vascular involvement of neuroblastomas and intraoperative vascular injuries were analyzed. A total of 61 patients had intraoperative vascular injuries, among which 76 vessels suffered injuries. Venous injuries (66/76, 86.84%) were more common than arterial injuries (10/76, 13.16%). Moreover, venous injuries frequently occurred in the inferior vena cava (32/66, 48.48%), renal veins (19/66, 28.79%), and iliac veins (8/66, 12.12%). All the injured arteries exhibited a total encasement on preoperative CT, and no injury occurred when the arteries were contacted or partially encased. In total, 87.88% (58/66) of injured veins were flattened with a visible lumen on preoperative CT, whereas only 12.12% (8/66) of the injured veins were flattened with an invisible lumen. Intraoperative injuries to veins occur more frequently than that to arteries in abdominal or pelvic neuroblastomas. Importantly, intraoperative injuries to veins may occur even if the veins are flattened with a visible lumen.

Laparoscopic Lateral Suspension (LLS) for the Treatment of Apical Prolapse: A New Gold Standard?

Nowadays, the gold standard to treat apical pelvic organ prolapse (POP) is laparoscopic sacrocolpopexy (LSCP). However, LSCP is a difficult procedure associated with rare but potentially severe complications. Promontory dissection may expose to potential life-threatening intraoperative vascular injuries, and sacral roots or hypogastric nerve damage. There are also a few case reports of spondylodiscitis with consecutive lumbar vertebra bone erosion. Laparoscopic lateral suspension (LLS) with mesh is an alternative technique for apical POP repair. It lowers perioperative risks by avoiding sacral promontory preparation. Recent studies show similar anatomical and functional outcomes to LSCP, with the advantage of better preserving the vaginal axis. Moreover, LLS is well suited for hysteropexy which is important as an increasing number of women prefer uterine preservation during POP surgery. In this article, we discuss both techniques, and we share our opinion on a novel perspective in the treatment of apical POP with uterine preservation.

Anterior lumbar spine exposure with vascular surgeon assistance

Objective:Evaluate access related complications contributing to adverse outcomes in patients undergoing retroperitoneal anterior lumbar interbody fusion (ALIF). MethodsA retrospective analysis was conducted of prospectively collected data on patients undergoing ALIF in a multidisciplinary setting at our institution from January 2007 to December 2021. Patients’ demographics, comorbidities, exposure related and postoperative complications within 30 days were included. Main outcome measures included vascular and visceral injuries requiring repair, nerve injuries, blood transfusion requirements, myocardial infarction, stroke, erectile dysfunction, retrograde ejaculation, length of stay and death. ResultsSeventy-four consecutive patients were included. Forty-seven were female and 27 male. The median body mass index was of 25.46 ± 4.76. Mean age was of 45.74 years. Twelve had a history of previous abdominal surgery and 31 a previous spinal surgery. The level operated on was L5/S1 in 58 patients (78.37%), L4/L5 in 2 patients (2.7%) and multi-level in 14 patients (18.91%). Sixteen patients had both anterior and posterior approach. There were no major intra-operative vascular injuries. Two patients had an intestine serosal tear. Seven patients had sexual dysfunction after surgery, of which 5 suffered impotence and 4 retrograde ejaculation. Two patients had both. There were no cases of disc space infections. There were no postoperative deaths. ConclusionsIn a multidisciplinary setting, ALIF can be performed safely with a reasonably low overall complication rate. Impotence and retrograde ejaculation are, even if generally temporary, important issues that have to be informed to the patient and inquired at follow up.

Evaluation of the Results of Patients Who Were Treated with Laparoscopic Simple Tunnel Hysterosacropexy Method to Prevent Uterine Prolapse: A New Approach

OBJECTIVES: To evaluate the results of patients with uterine prolapse who underwent laparoscopic simple tunnel hysterosacropexy as uterine protective surgery. In this surgical procedure, the parietal peritoneum which was cut off in traditional surgery is preserved. STUDY DESIGN: Data from women with apical prolapse of stage 2 or higher who underwent laparoscopic simple tunnel hysterosacropexy between October 1, 2017, and March 31, 2019, at the University of Health Sciences Diyarbakır Gazi Yasargil Education and Research Hospital, Diyarbakır, Turkey was retrospectively assessed. Patients were treated with laparoscopic simple tunnel hysterosacropexy; the meshes were anchored to the posterior cervical area, even in the presence of advanced multi-compartment vaginal prolapse. Data on the prolapse stage and urogenital functions were collected through clinical examinations, questionnaires at baseline, and 6 months after the operation. Results were analyzed using Wilcoxon Signed Ranks Test and Based on positive ranks. Data are presented as mean, minimum, maximum or percentage according to variables. RESULT: Overall, 12 women were included in the analysis; the mean follow-up was 6 months. There were significant improvements in the complaints and POP-Q values of patients included in the study. There were not any complications during the intraoperative period and postoperative follow-ups. During the first six-month follow-up, there were not any recurrence of prolapse. The mean operative time was 146 minutes; there were no intraoperative visceral or vascular injuries. There was no recurrence or vaginal erosion. CONCLUSION: In patients with stage 2 and more severe uterine prolapse, laparoscopic simple tunnel hysterosacropexy can be performed without cutting the peritoneum. Since the peritoneum is not cut during the surgery; intestinal injury prevalence and mesh exposure rates are lower.

Cerebrovascular Complications of Vestibular Schwannoma Surgery.

Objective Cerebrovascular complications (CVC) are rare consequences of vestibular schwannoma (VS) surgery. Our objective was to assess incidences of findings suggestive of postoperative CVC in a large single surgeon cohort, as well as potential risk factors, and implications. Study Design A cohort of 591 patients was retrospectively reviewed. Postoperative magnetic resonance images were screened for findings suggestive of stroke, T2 hyperintensity in the cerebellopontine angle structures or new encephalomalacia. Clinical records were queried for findings consistent with postoperative CVC. Results In total, 61 patients had radiographic findings consistent with possible postoperative CVC (10%); of them, eight had documented intraoperative vascular injury (1.4%), and four had postoperative clinical exam changes indicative of CVC (0.7%). Clinically manifest intraoperative vascular injuries occurred in four patients and involved the petrosal venous complex ( n = 3, 5%) or anterior inferior cerebellar artery ( n = 1, 2%); clinical deficits included hemiparesis ( n = 1, 2%), facial anesthesia ( n = 2, 4%), dysphagia ( n = 2, 2%), and unfavorable facial nerve function in two (50%). Three out of four patients in this group required out-of-home placement (75%). Clinical CVCs ( n = 4) were not significantly associated with tumor size, tumor cyst, gross total resection, or length of stay. Patients with clinical CVC were significantly more likely to require posthospitalization rehabilitation (19 vs. 75%, p = 0.02; 14 vs. 100%, p = 0.0002). Conclusion Although radiographic findings suggestive of CVC were unexpectedly common in this cohort, intraoperative vascular injury and postoperative clinical CVC were exceedingly rare. The association between unfavorable facial nerve outcome and clinical CVC is likely a marker for more difficult operations, predisposing to higher risk of complications.

Chopstick technique used in laparoendoscopic single site radical hysterectomy for early stage cervical cancer

Laparoendoscopic single-site surgery (LESS) further minimizes the invasiveness of traditional laparoscopic surgery. However, the "chopstick" effect caused by the parallel arrangement of the instruments in the umbilicus is considered an obstacle indelicate operations. The purpose of this study was to introduce a new technique characterized by a double fulcrum formed by instruments, named the "chopstick" technique, which facilitates the expedient accomplishment of complicated surgeries such as LESS radical hysterectomy (LESS-RH). Seventy-three patients who underwent LESS-RH using the "chopstick" technique were retrospectively analyzed. The procedure was performed successfully in 72 patients. The median operative duration was 225 min, and the median intraoperative blood loss was 200 ml. Among the operations in the first 20 patients, intraoperative vascular injuries and bladder injury occurred in two patients and were repaired by LESS. Patients responded positively regarding minimal postoperative pain control. The score of satisfaction with the cosmetic outcome expressed by the patients was eight at discharge and nine 30 days later. In conclusion, this study presents the feasibility of accomplishing complicated procedures, such as radical hysterectomy, by LESS using the “chopstick” technique. This approach provides more options for both selected patients and surgeons.

Expanded transnasal approaches to the skull base in the Middle East: Where do we stand?

ABSTRACTBACKGROUND: Endoscopic transnasal surgery has gained rapid global acceptance over the last two decades. The growing literature and understanding of anterior skull base endoscopic anatomy, in addition to new dedicated endoscopic instruments and tools, have helped to expand the use of the transnasal route in skull base surgery.OBJECTIVE: Report our early experience in expanded endoscopic transnasal surgery (EETS) and approach to skull base neoplasms.DESIGN: Descriptive, retrospective case series.SETTING: Major tertiary care center.PATIENTS AND METHODS: A retrospective case review was conducted at King Saud University Medical City between December 2014 and August 2019. Cases with skull base neoplasms that underwent EETS were included. EETS was defined as endoscopic surgical exposure that extended beyond the sellar margins (prechiasmatic sulcus superiorly, clival recess inferiorly, cavernous carotid lines laterally). Routine transsphenoidal pituitary neoplasms, neoplasms of sinonasal origin and meningoencephaloceles were excluded.MAIN OUTCOME MEASURES: Preoperative clinical assessment, imaging results, surgical approach, and hospital course were all retrieved from the patient electronic charts. Clinical follow-up, perioperative complications, and gross residual tumor rates were documented and reviewed.SAMPLE SIZE AND CHARACTERISTICS: 45 cases of EETS, 13 males and 32 females with mean age of 39.0 (17.7) years (range 2–70 years).RESULTS: The series comprised a wide range of pathologies, including giant pituitary adenoma (8 cases), meningioma (23 cases), craniopharyngioma (4 cases), chordoma (4 cases), optic pathway glioma (2 cases), epidermoid neoplasms (2 cases), astrocytoma (1 case), and teratoma (1 case). For the entire series, gross total resection was achieved in 25/45 operations (55.5%). Postoperative cerebrospinal fluid leak was the most common complication observed in 9 patients (20%) which were all managed endoscopically. Major vascular complications occurred in 2 patients (4.4%) and are described. Other complications are outlined as well. No mortality was observed.CONCLUSIONS: EETS to the skull base can be done with results comparable to traditional approaches. More work is needed to expand our experience, improve outcomes, and educate the public and medical community in our region about the usefulness of this approach.LIMITATIONS: Sample size and study design.CONFLICT OF INTEREST: None.

1704 Application of “Chopstick Technique” In Laparoendoscopic Single-Site Radical Hysterectomy: Initial Single-Institutional Experience for Early Stage Cervical Cancer

Design Retrospective study. Setting The First Affiliated Hospital of Third Military Medical University, Chongqing, China. Patients or Participants Women with federation international of gynecology and obstetrics (FIGO) stage Ia1 with lymph vascular space invasion or stage Ia2-IIa2 cervical cancer. Interventions “Chopstick technique” was performed in LESS-RH and pelvic lymph node dissection. The demographic characteristics and perioperative efficacy of the patients were summarized and analyzed. Measurements and Main Results LESS-RH was attempted in 84 patients, and 83 (98%) patients underwent the procedure successfully. One patient underwent conversion to traditional laproscopic surgery secondary to phase IV endometriosis. “Chopstick technique” was used in all the 83 cases, wherein 40 cases used the single-incision three-channel laparoscopy platform, and 43 used the multichannel-tipped single port laparoscopy platform (HangT Port). The average operation time was 225.0±50.2min and the median intraoperative blood loss was 100mL. During the operations in the first 20 cases, 2 patients had intraoperative vascular injuries and 1 patient had bladder injury, and all were repaired under LESS. One case had ureterovaginal fistula 14 days after operation, and was successfully repaired by ureteroneocystostomy. The average number of pelvic lymph node dissections was 21, and the pathological examination of incisal edge was negative. Deep stromal invasion in 43 cases, LVSI in 16 cases,positive parametrium in 1 case, positive pelvic nodes in 15 cases. 33 patients were treated with postoperative chemotherapy and radiotherapy and 19 patients with intermediate risk factors were treated with radiotherapy postoperatively. Conclusion “Chopstick technique” under LESS was considered feasible for treating cervical cancer.

Options and Management of Vascular Reconstruction in the Context of Abdominal Surgery and its Perioperative Care - Selection of Typical Clinical Situations and Cases

Interdisciplinary cooperation between surgeons can help to optimise outcome in the management of complex surgical diseases. The indication for surgical intervention has gradually expanded in advanced multivisceral tumour growth, with iatrogenic vascular injuries in the field of abdominal and oncological surgery and mesenteric ischemia. Appropriate expertise in vascular surgery is then essential, although this is not always available or in all hospitals. Narrative review based on current scientific references in the relevant literature and our own clinical and surgical experiences in decision making, the approach in clinical management and various options of vascular reconstruction in abdominal surgery. Prognosis is still limited in pancreatic cancer. R0 resection is the only curative therapeutic option - thus, the surgeon has to provide specific intraoperative expertise. Arterial reconstruction is still controversial, due to increased postoperative morbidity and limited evidence. But in specific cases, venous reconstruction has been established in clinical practice. In addition, in retroperitoneal sarcoma with advanced/extended tumour growth, reconstruction of the infiltrated inferior V.cava or common iliac artery by means of patch plasty or autologous bypass/segmental vascular prosthesis can become necessary as part of multivisceral resections. During inflammatory processes or with tumour adhesions/infiltrations to surrounding anatomical structures, intraoperative vascular injuries or postoperative vascular alterations can occur, further complicated by anatomical variants. The extremely strict demands on the abdominal surgeons, in particular in mesenteric ischemia, are influenced by i) a competent assessment of the mesenteric vessels based on ii) adequate imaging as well as iii) appropriate time management. Prompt recanalisation can play a decisive role for the prognosis. Vascular reconstructions in abdominal surgery, in particular, in oncological surgery, require great expertise of the surgeon. In this context, competent preoperative diagnostic testing, extensive specific experience in vascular surgery/interventions, appropriate interdisciplinary case management, adequate surgical tactic and technique are all important.

Advance in research on anterior occipitocervical fixation and fusion

The stability of the occipitocervical region mainly depends on the integrity of the bony structure, surrounding ligaments and joint capsules. The instability of this region often leadsto the clinical symptoms of compression injury of nerve and vascular, which requires early surgical intervention to rebuild its stability. Posterior occipitocervical fixations are main surgical treatment for the occipitocervical diseases. However, the posterior fixations are not suitable for some patients with congenital or iatrogenic causes. Recently, the anterior occipitocervical fixation with the screws anchored at clivus or into the occipital condyles have been used for the following operations. 1. Anterior bone graft fusion. One case which was performed by oral approach was reported well fusion, but the stability was poor and there was a possibility of displacement. 2. Anterior shaped titanium cage and plate fixation. The literatures reported that this anterior operation was completed in 35 cases by oral, oral combined with mandibulotomy, and anterior retropharyngeal approaches. This fixation has a good biomechanical stability and is widely used in clinical applications, including occipitocervical tumors and deformities. And the complications including intraoperative vascular, spinal and dural injuries, postoperative drinking cough, non-fusion, deep infection, and death. 3. Anterior occipital-atlantoaxial joint screw fixation. Seven cases were performed by anterior occipital-atlantoaxial joint screw fixation through anterior percutaneous approach. This fixation is less trauma, but required precise placement of screw and not conducive bone fusion, and it is suitable for traumatic instability of the upper cervical spine, atlantoaxial dislocation and basilar invagination. Each procedure of anterior occipitocervical fixation is not suitable for all patients, and it should be adopted according to the patient's condition, surgical hardware conditions and the surgeon's habits.

Vascular Injury During Urologic Surgery: Somebody Call My Mother.

To provide the critical elements to effectively manage hemorrhage from vascular injuries sustained during planned urological interventions. The frequency of intraoperative vascular injuries is increasing. However, literature concerning the management of iatrogenic operative vascular injuries is scarce. Although rare, intraoperative vascular injuries may be associated with potential catastrophic complications and death. The decision-making process following a potential life-threatening intraoperative vascular injury occurs in a very short time frame. Appropriate knowledge of the critical elements to identify the source of bleeding, initiate first-line hemostatic measures, select the candidate for damage control strategies, and perform the indicated operative repairing maneuvers and techniques have been proved crucial to ensure hemodynamic stability and bleeding cessation. The key surgical principles to counteract the impact of exsanguinating bleeding, and the aim to obtain the best achievable outcomes after definitive repair, are described in detail in this review.

Optimizing the laparoscopic steps in right colectomy with complete mesocolic excision to reduce the intraoperative vascular injuries

Laparoscopic right colectomy by the rule of complete mesocolic excision is becoming a standard operation for right colon cancer. Intraoperative iatrogenic vascular injuries are rare but disastrous complications. In addition to the dissection along the embryonic plane, reducing iatrogenic bleeding is of crucial importance to safeguard the surgical procedure. Keeping the operative field clear by gentle suction to have a good exposure is essential to identify the origin of bleeding, and then to make decision how to control the bleeding by bipolar coagulation, clipping and transection, suturing or conversion to open surgery. For small bleeding, the grasping forceps with bipolar coagulation or clipping would usually be effective. When there is laceration locating on the stem of superior mesenteric vein or Henle trunk, suturing with 4-0 or 5-0 prolene monofilament is suggested. Self-saphenous graft or bridge is advised for stem stricture after suturing. The ileocolic vessels are most anatomically constant, but with a different relationship between the artery and the vein. The tributaries to form the Henle trunk vary quite often, and they usually have close relation to the middle colic vein. Right colic artery rarely arises from the superior mesenteric artery, and the right colic vein seldom drains into the superior mesenteric vein. Anatomical variations are commonly observed in the pancreaticoduodenal area, where bleeding happens frequently. Selecting an optimal laparoscopic approach and dissecting order, awareness of vascular variation, and understanding the anatomical configuration of superior mesenteric vessels and their tributaries are important to minimize the intraoperative iatrogenic injuries during the meticulous dissections.
