Abstract OBJECTIVE To describe a frameless stereotactic technique used to resect cerebral arteriovenous malformations (AVMs) and to determine whether frameless stereotaxy during AVM resection could decrease operative times, minimize intraoperative blood losses, reduce postoperative complications, and improve surgical outcomes. METHODS Data for 44 consecutive patients with surgically resected cerebral AVMs were retrospectively reviewed. The first 22 patients underwent resection without stereotaxy (Group 1), whereas the next 22 patients underwent resection with the assistance of a frameless stereotaxy system (Group 2). RESULTS The patient characteristics, AVM morphological features, and percentages of preoperatively embolized cases were statistically similar for the two treatment groups. The mean operative time for Group 1 was 497 minutes, compared with 290 minutes for Group 2 (P = 0.0005). The estimated blood loss for Group 1 was 657 ml, compared with 311 ml for Group 2 (P = 0.0008). Complication rates, residual AVM incidences, and clinical outcomes were similar for the two groups. CONCLUSION Frameless stereotaxy allows surgeons to 1) plan the optimal trajectory to an AVM, 2) minimize the skin incision and craniotomy sizes, and 3) confirm the AVM margins and identify deep vascular components during resection. These benefits of stereotaxy were most apparent for small, deep AVMs that were not visible on the surface of the brain. Frameless stereotaxy reduces the operative time and blood loss during AVM resection.

Objective: To compare the effect of cord clamping time on the incidence of neonatal anemia, clinical outcomes, and maternal and neonatal complications in term vaginal delivered newborns. Materials and Methods: A randomized controlled study was undertaken. Two hundred forty healthy full term vaginal delivered newborns were randomly allocated to either 30-seconds, 1-minute, or 2-minutes groups (group 1, 2, and 3) of umbilical cord clamping. During the interval between delivery and cord clamping, the attendant held the neonate supine at the level of the introitus. Neonatal venous hematocrit (Hct) was measured at 48 to 72 hours after birth. Results: Two hundred thirty newborns completed the present study. Neonatal anemia (Hct less than 45%) was detected in six of 77 cases (7.8%) in group 1, five of 76 cases (6.6%) in group 2, and three of 77 case (3.9%) in group 3, and there were no significant differences among the groups. Mean venous hematocrit values at 48 to 72 hours of life ± standard deviations were 53.1±6.4% in group 1, 53.0±5.5% in group 2, and 53.0±5.7% in group 3. The incidence of polycythemia (hematocrit more than 65%) and neonatal jaundice were similar among all the groups. There were no significant differences in the estimated postpartum blood loss and other neonatal outcomes. Conclusion: Neonatal hematocrit was not significantly different following delayed cord clamping (DCC) at 30-seconds, 1-minute, and 2-minutes, but the incidence of neonatal anemia decreased with the longer timing of DCC. The estimated blood loss and other complications were not different between the groups. Therefore, a minimum of a one minute DCC should be considered for neonatal anemic prevention when compared with the 30-seconds DCC.

Background: Several techniques and devices have been described for circumcision each with its own pros and cons. The objective of this study was to compare the outcome of neonatal circumcision between bone-cutter and plastibell devices at our institution. Methods: This is a randomized trial (unregistered) conducted at the Pediatric Surgical Unit of a tertiary teaching hospital situated in a semi-urban setting, between January 2019 and December 2019. The uncircumcised neonates underwent circumcision by either bone-cutter or plastibell device. Demographic characteristics, operative time, estimated blood loss, and postoperative complications were compared. A p-value of <0.05 was considered significant. Results: The age ranged between 7 days and 30 days with a mean of 15.9±5.5 days. The mean age and weight of both groups were well matched (p >0.05). The operative time in the bone cutter technique was 4.2±0.9 minutes compared to 5.8±1.2 minutes in the plastibell device method (p <0.001). Blood loss was lesser with bone cutter (0.27 ±0.32mls versus 0.51 ±0.44mls in the plastibell device, p <0.001). The complication rates were comparable in both study groups (p =1.000). The overall complication rate was 5.8%. The penile perception score and the Hollander wound evaluation score for bone-cutter were 15.7±0.8 and 5.7±0.84 while in the plastibell device were 15.4±1.1 and 5.4±1.1, respectively (p >0.05). Conclusion: Operative time and blood loss were less with bone cutter compared to plastibell device. However, the complication rate, penile perception score, and Hollander wound evaluation scores were similar.

OBJECTIVEWith global aging, elective craniotomies are increasingly being performed in elderly patients. There is a paucity of prospective studies evaluating the impact of these procedures on the geriatric population. The goal of this study was to assess the safety of elective craniotomies for elderly patients in modern neurosurgery.METHODSFor this cohort study, adult patients, who underwent elective craniotomies between November 1, 2011, and October 31, 2018, were allocated to 3 age groups (group 1, < 65 years [n = 1008], group 2, ≥ 65 to < 75 [n = 315], and group 3, ≥ 75 [n = 129]). Primary outcome was the 30-day mortality after craniotomy. Secondary outcomes included rate of delayed extubation (> 1 hour), need for emergency head CT scan and reoperation within 48 hours after surgery, length of postoperative intensive or intermediate care unit stay, hospital length of stay (LOS), and rate of discharge to home. Adjustment for American Society of Anesthesiologists Physical Status (ASA PS) class, estimated blood loss, and duration of surgery were analyzed as a comparison using multiple logistic regression. For significant differences a post hoc analysis was performed.RESULTSIn total, 1452 patients (mean age 55.4 ± 14.7 years) were included. The overall mortality rate was 0.55% (n = 8), with no significant differences between groups (group 1: 0.5% [95% binominal CI 0.2%, 1.2%]; group 2: 0.3% [95% binominal CI 0.0%, 1.7%]; group 3: 1.6% [95% binominal CI 0.2%, 5.5%]). Deceased patients had a significantly higher ASA PS class (2.88 ± 0.35 vs 2.42 ± 0.62; difference 0.46 [95% CI 0.03, 0.89]; p = 0.036) and increased estimated blood loss (1444 ± 1973 ml vs 436 ± 545 ml [95% CI 618, 1398]; p <0.001). Significant differences were found in the rate of postoperative head CT scans (group 1: 6.65% [n = 67], group 2: 7.30% [n = 23], group 3: 15.50% [n = 20]; p = 0.006), LOS (group 1: median 5 days [IQR 4; 7 days], group 2: 5 days [IQR 4; 7 days], and group 3: 7 days [5; 9 days]; p = 0.001), and rate of discharge to home (group 1: 79.0% [n = 796], group 2: 72.0% [n = 227], and group 3: 44.2% [n = 57]; p < 0.001).CONCLUSIONSMortality following elective craniotomy was low in all age groups. Today, elective craniotomy for well-selected patients is safe, and for elderly patients, too. Elderly patients are more dependent on discharge to other hospitals and postacute care facilities after elective craniotomy.Clinical trial registration no.: NCT01987648 (clinicaltrials.gov).

Abstract Aim Closed suction drains (CSD) are routinely used to reduce the risk of haematoma formation and wound infections in TKA. Our study aims to determine if the use of drains has any impact on estimated blood loss, transfusion rates and length of stay in hospital. Method Elective TKA cases performed under a single consultant between February 2018-March 2020 were identified. Electronic medical records were reviewed, and data collected on relevant variables. Estimated blood loss was calculated using Ward’s formula. Mann-Whitney U test was applied to assess for statistical significance. Results A total of 86 elective TKA cases were included in the study. In 41 cases patients had a CSD insitu post-operatively (group 1), in the other 45 cases a drain was not used (group 2). Both groups had similar distributions of age, BMI, and sex. We found no statistically significant differences in mean change (+/-SD) in haemoglobin post-operatively between group 1 (21.3 (+/- 9.4)) and group 2 (19 (+/- 10)), (p = 0.34). Mean estimated blood loss was 915mls (+/-365) for group 1 and 871mls (+/-455) for group 2, (p = 0.45). Group 1 had a higher rate of transfusion (4.8% vs 2.2%); however, this was not statistically significant (p = 0.51). After accounting for unrelated medical complications or social barriers to discharge, the length of hospital stay was 4.7 (+/- 2.27) and 4.9 (+/- 3.14) for group 1 and 2 respectively, (p = 0.84). There were no reported cases of wound infection in both groups. Conclusions We found the use of drains in TKA confers no benefits in the outcomes evaluated.

Good outcome has been reported with the laparoscopic approach in uncomplicated appendicitis, but a higher incidence of postoperative intraabdominal abscesses has been reported after laparoscopic appendectomy in complicated appendicitis. This retrospective comparative study compares outcome after laparoscopic (LA) and open appendectomy (OA) in complicated appendicitis. All patients who had LA or OA for complicated appendicitis between January 2003 and February 2006 were included in the study. Data collection included demographics, operative time, estimated blood loss, length of stay (LOS), complications, readmission, and reoperative rates. The primary end points for analysis were postoperative intraabdominal abscess and complication rates and secondary end points were LOS and operative time. All data were analyzed on an intent-to-treat basis. Of 104 patients, 43 patients underwent LA and 61 had OA. The mean age (24.8 ± 16.5 versus 31.3 ± 18.9, P = 0.08) in the LA group was lower than the OA group because there was a significantly higher proportion of pediatric patients (34.8% versus 14.8%, P = 0.02) who had LA. There was no significant difference in gender (female/male, 14/29 versus 27/34, P = 0.3) or American Society of Anesthesiologists class distribution (American Society of Anesthesiologists 1/2/3/4/, 35/7/1/0 versus 45/12/3/1, P = 0.68) between the two groups. The operative time (100.5 ± 36.2 versus 81.5 ± 29.5 minutes, P = 0.03) was significantly longer and the estimated blood loss (21 mL versus 33 mL, P = 0.01) was lower in LA when compared with OA, but there was no significant difference in the number of patients with preoperative peritonitis versus abscesses (7/36 versus 13/48, P = 0.6) in both groups. There was no difference in the median LOS (6 [interquartile range 5–9] versus 6 [interquartile range 4–8], P = 0.7) in the two groups. The conversion rate in LA was 18.6% (n = 8). There was also no significant difference in the complication (17/43 [39.5%] versus 21/61 [34.4%], P = 0.54), reoperative (3/43 [7%] versus 0/61 [0%], P = 0.07), and 30-day readmission (5/41 [11.6%] versus 3/61 [4.9%], P = 0.23) rates between the two groups. The rate of postoperative intraabdominal abscesses was significantly higher in the LA group when compared with the OA group (6/43 [14%] versus 0/61 [0%], P = 0.04) and the wound infection (1/43 [2.3%] versus 5/61 [8.2%], P = 0.4) and pulmonary complication (0/43 [0%] versus 3/61 [4.9%], P = 0.26) rate was higher in the OA group. There was no mortality in the LA group, but there was one mortality in the OA group resulting from postoperative myocardial infarction. Laparoscopic appendectomy can be performed in patients with complicated appendicitis with a comparative operative time, LOS, and complication rates but results in a significantly higher intraabdominal abscess rate and lower wound infection rate when compared with OA.

Little data is available regarding complications associated with resection arthroplasty in the treatment of hip periprosthetic joint infection (PJI). We assessed complications during and after two-stage revision using resection arthroplasty. In this retrospective study, 93 patients undergoing resection arthroplasty for hip PJI were included. Patients were assigned to a prosthesis-free interval of ≤10 weeks (group 1; 49 patients) or >10 weeks (group 2; 44 patients). The complication rates between groups were compared using the chi-squared test. The revision-free and infection-free survival was estimated using a Kaplan–Meier survival analysis. Seventy-one patients (76%) experienced at least one local complication (overall 146 complications). Common complications were blood loss during reimplantation (n = 25) or during explantation (n = 23), persistent infection (n = 16), leg length discrepancy (n = 13) and reinfection (n = 9). Patients in group 1 experienced less complications after reimplantation (p = 0.012). With increasing severity of acetabular bone defects, higher incidence of complications (p = 0.008), periprosthetic bone fractures (p = 0.05) and blood loss (p = 0.039) was observed. The infection-free survival rate at 24 months was 93.9% in group 1 and 85.9% in group 2. The indication for resection arthroplasty needs to be evaluated carefully, considering the high rate of complications and reduced mobility, particularly if longer prosthesis-free intervals are used.

Objective: To compare outcomes of video assisted Thoracoscopic Decortication (VATD) with conventional open decortication (COD) in patients with stage–II or stage–III empyema thoracic. Study Design: Prospective comparative study. Place and Duration of Study: Department of Thoracic Surgery, Combined Military Hospital, Rawalpindi, Pakistan, from Jun 2018 to May 2019. Methodology: A total 60 patients underwent in this study. Patients of both gender who reported for decortication of empyema thoracic were evaluated. All patients diagnosed to have Stage II or III empyema with age 25-50 years were studied for outcomes. All patients were evaluated for operative time, blood loss, post-operative pain, pneumonitis, duration of airleak and post-operative drainage, duration of chest drains and length of hospital stay. Results: Mean operative time in group-1 was 133.63 ± 8.55 min and in group-2 was 147.83 ± 10.36 min (p-value 0.037). Mean blood loss in group-1 was 296.66 ± 46.11 while in group-2 was 207.30 ± 53.81. Post-operative pain score on VAS for pain was 5.8 ± 1.7 for group-1 and 4.06 ± 1.4 for group-2 (p-value 0.032). Chest tubes were retained for an average of 5.58 ± 0.8 days in group-1 while 3.86 ± 0.8 days in group-2 (p-value <0.001). Conclusion: Video-Assisted Thoracoscopic Surgery Decortication is superior to open decortication in operative management of Stage II and Stage III Empyema thoracic in terms of post op pain, duration of chest intubation, air leak and hospital stay of the patient.

✓ Endovascular therapy of cerebral arteriovenous malformations (AVM's) is an accepted adjunct to surgical therapy. However, the literature has not characterized the benefits or the liabilities of preoperative embolization. This series compares two groups of patients who underwent surgical resection of a cerebral AVM; one group (20 patients) received preoperative transfemoral selective embolization with N-butyl cyanoacrylate (NBCA) and the other group (13 patients) did not. In the group with preoperative embolization, the AVM's were larger (3.9 vs. 2.3 cm) and of a higher Spetzler-Martin grade (3.2 vs. 2.5) as compared to the nonembolized group. The NBCA embolization facilitated surgical resection. Arteries supplying the vascular malformation were readily distinguished from those supplying the normal brain parenchyma. Embolized vessels were compressible and easily cut with microscissors. No bleeding occurred from transected vessels. Operative time and intraoperative blood loss for the two groups were not statistically different, despite the significant differences in lesion size and grade. Endovascular complications included immediate and delayed hemorrhage (15%) and transient ischemia (5%); there were no embolization-related deaths. Postoperative complications for both groups included hemorrhage (15%), residual AVM (6%), and cerebrospinal fluid leak (3%); the mortality rate was 3%. There was no statistically significant difference in surgical complications between the embolized and nonembolized groups. Most patients (91%) in both groups had an excellent or good late neurological outcome, with no significant difference between the groups. This study concludes that preoperative NBCA embolization of AVM's makes lesions of larger size and higher grade the surgical equivalent of lesions of smaller size and lower grade by reducing operative time and intraoperative blood loss, with no statistically significant difference in surgical complications or long-term neurological outcome.

Abstract Background To evaluate the efficacy and safety of Holmium YAG laser circumcision in adolescents. Methods Eighty-one patients underwent circumcision for medical reasons, and patients’ requests were collected retrospectively during February 2017 to February 2019. They were divided into two groups: Holmium YAG laser (group 1, n = 41) and conventional group (group 2, n = 40). The guillotine method with a Holmium YAG laser was applied for circumcisions, and all the procedures were performed by a single urologist who was well-experienced with circumcision practices. Results The average age of group 1 was 15.53 ± 7.35 years old, and the average age was 16.34 ± 9.22 years old in group 2. There was no significant difference in age and indications. The average operative time was significantly shorter in group 1 than in group 2 (24.40 ± 3.94 vs. 27.25 ± 4.35 min, p < 0.01). The estimated blood loss was less in group 1 compared to group 2. There were fewer complications in group 1 than in group 2 (3/41 vs. 10/40, p < 0.01) and patients also felt less pain in group 1 (p < 0.01). All patients tolerated this procedure without severe side effects. Conclusions The use of Holmium YAG laser in circumcision is a novel, less complicated, easy, and less painful alternative procedure for circumcision in young males.

Introduction: Hysterectomy is one of the frequently performed major gynecological surgicalprocedures for various uterine pathologies. The objective of this study is to assess the effect ofintravenous tranexamic acid in reducing intraoperative and postoperative blood loss in womenundergoing abdominal hysterectomy. Materials and Methods: The study was a randomizeddouble-blind study, involving a total of 120 women undergoing abdominal hysterectomy for benignetiology were randomly assigned to two groups: Group 1 (non TA): (n=60) women receiving normalsaline and Group 2 (TA): (n=60) women receiving prophylactic Tranexamic Acid in 100 ml saline IVjust before skin incision. The primary outcome was intraoperative, postoperative, and all blood lossestimation. Results: Group 2 (TA) showed a great reduction in intraoperative and postoperativeblood loss (blood in the intra-abdominal drain) compared with Group 1 (non TA), (P = 0.0001,0.0001), so the overall estimated blood loss in groups 2 showed significant reduction compared withGroup 1 (P = 0.0001). Conclusion: Intravenous tranexamic acid is a safe and reliable method tohelp decrease blood loss during and after abdominal hysterectomy.
