Frequent Intraoperative Complications Research Articles

Evaluating the Safety of Retrograde Intrarenal Surgery (RIRS): Intra- and Early Postoperative Complications in Patients Enrolled in the Global Multicentre Flexible Ureteroscopy Outcome Registry (FLEXOR).

To assess the incidence of the most common intra- and early postoperative complications following RIRS in a large series of patients with kidney stones. We conducted a retrospective analysis of patients with kidney stones who underwent RIRS across 21 centers from January 2018 to August 2021, as part of the Global Multicenter Flexible Ureteroscopy Outcome (FLEXOR) Registry. Among 6669 patients undergoing RIRS, 4.5% experienced intraoperative pelvicalyceal system bleeding without necessitating blood transfusion. Only 0.1% of patients, required a blood transfusion. The second most frequent intraoperative complication was ureteric injury due to the ureteral access sheath requiring stenting (1.8% of patients). Postoperatively, the most prevalent early complications were fever/infections requiring antibiotics (6.3%), blood transfusions (5.5%), and sepsis necessitating intensive care unit admission (1.3%). In cases of ureteric injury, a notably higher percentage of patients exhibited multiple stones and stone(s) in the lower pole, and these cases were correlated with prolonged lasing and overall surgical time. Hematuria requiring a blood transfusion was associated with an increased prevalence of larger median maximum stone diameters, particularly among patients with stones exceeding 20 mm. Furthermore, these cases exhibited a significant prolongation in surgical time. Sepsis necessitating admission to the intensive care unit was more prevalent among the elderly, concomitant with a significantly larger median maximum stone diameter. Our analysis showed that RIRS has a good safety profile but bleeding requiring transfusions, ureteric injury, fever, and sepsis are still the most common complications despite advancements in technology.

Evaluation of Factors That Contribute to Intraoperative and Postoperative Complications Following Colorectal Cancer Surgeries at King Abdulaziz University Hospital, Jeddah, Saudi Arabia.

Colorectal cancer (CRC) is a major contributor to cancer-related mortality and morbidity due to its high prevalence. Surgery remains the curative option. Colorectal cancer patients come to our institute at an advanced stage due to the lack of adequate national screening programs in developing countries. This carries a particularly high risk of morbidity and mortality. In this study, we aim to provide an overview of the complications of colorectal cancer surgery and to describe the preoperative and intraoperative factors associated with it. This retrospective record review was done at King Abdulaziz University Hospital (KAUH), a tertiary center in Jeddah, Saudi Arabia. It included all patients aged 18 and older who have undergone colorectal cancer surgeries from January 2017 until August 2022. In our sample of 195 patients, 52.3% of the patients were males. The mean age of our sample was 59.32 ± 13.21. We found that 19 (9.7%) patients had an intraoperative complication (IOC). The most frequent IOC was bleeding reported in seven patients (3.6%), followed by intestinal injury in three (1.2%), bladder injury in three (1.2%), and ureter injury in three (1.2%). Regarding preoperative lab tests, patients who had low blood albumin levels (P = 0.004) and high preoperative white blood cell count (WBC; P = 0.015) were more likely to experience IOC. There was a statistically significant relationship between the patient's ASA score and IOC (P = 0.011).Postoperative complications (POC) occurred in 58 patients (29.7%). The most frequent POC was surgical site infection (SSI; 16.4%), followed by urinary tract infections (UTI) (6.7%) and prolonged postoperative ileus (5.6%). Patients who initially presented with vomiting (P = 0.015), had free air on a preoperative abdominal computed tomography (CT) scan (P = 0.028), required intraoperative blood transfusions (P = 0.033), were diagnosed with transverse colon tumors (P = 0.045), and required longer hospital stays (P = 0.011) were found to have a higher rate of POC. The incidence of colorectal cancer is increasing, and surgery is a successful treatment option. However, complications from surgery may result in morbidities and prolonged hospital stays. The risk of IOC is increased by preoperative variables such as high WBC levels, low albumin, and ASA scores. Patients with initial obstruction signs, free air on CT scans, intraoperative blood transfusions, transverse colon tumors, and longer hospital stays have a higher rate of POC. Patient monitoring and the provision of standardized clinical tools enhance general survival and quality of life.

Perioperative complications and oncological outcomes of post-chemotherapy retroperitoneal lymph node dissection in patients with germ cell cancer at two high-volume university centres in Switzerland – a retrospective chart review

Post-chemotherapy retroperitoneal lymph node dissection (PC-RPLND) is an integral part of the management of patients with metastatic non-seminoma and residual masses >1 cm after chemotherapy. To assess perioperative complications and oncological outcomes at two major referral centres in Switzerland. This was a retrospective chart review of 136 patients with non-seminoma who underwent PC-RPLND between 2010 and 2020 at the university hospitals of Bern and Zürich. Patient, treatment and tumour characteristics as well as the types and frequencies of intra- and postoperative complications were registered and compared using the chi-square test. Oncological outcomes consisted of the time and location of relapses as well as progression-free and overall survival, which were compared using the log-rank test. Overall, 70 patients from Bern and 66 patients from Zürich were included; 5 patients had a previous retroperitoneal lymph node dissection (RPLND) (2 Bern, 3 Zürich). Vascular injuries were the most frequent intraoperative complication, occurring in 27/136 (19.9%) patients. Postoperative complications were observed in 42/136 (30.9%) patients, ileus being the most common. Perioperative mortality was 2.2%. A retroperitoneal mass ≥50 mm was significantly associated with intraoperative complications (p = 0.004) and increased resource demands (p = 0.021). Postoperative morbidity was higher according to age at post-chemotherapy retroperitoneal lymph node dissection ≥40 years (p = 0.028) and retroperitoneal mass ≥20 mm (p = 0.005). The median follow-up time was 37 months (interquartile range [IQR] 18-64 months). The median progression-free survival at 5 years was 76% (95% confidence interval [CI]: 64-85%) in Bern and 69% (95% CI: 54-80%) in Zürich (p = 0.464). The median overall survival at 5 years was 88% (95% CI: 76-94%) in Bern and 77% (95% CI: 60-87%) in Zürich (p = 0.335). Patients with progressive disease or a tumour marker increase before retroperitoneal lymph node dissection had significantly inferior progression-free and overall survival compared to non-progressing patients. The presence of teratoma in resected specimens did not confer inferior survival probabilities compared to necrosis only, whereas the presence of vital undifferentiated tumour conferred inferior progression-free and overall survival. Patients with a previous retroperitoneal lymph node dissection and patients operated for late relapses >2 years after chemotherapy also had significantly inferior progression-free and overall survival. We found a relevant rate of severe perioperative complications at PC-RPLND at even experienced high-volume centres. The oncological outcomes at two major university urological centres in Switzerland were similar and determined by preoperative risk factors and intraoperative histology.

Clinical Outcomes of Combined Phacoemulsification With Intraocular Lens Placement and Microincision Vitrectomy in Adult Vitreoretinal Disease.

To evaluate the safety and clinical outcomes of combined phacoemulsification with intraocular lens (IOL) placement and microincision vitrectomy surgery (MIVS) in adult patients with concomitant cataract and vitreoretinal disease. A consecutive series of patients with comorbid vitreoretinal disease and cataract who had combined phacoemulsification with IOL placement and MIVS was retrospectively analyzed. The main outcome measures were visual acuity (VA) and intraoperative and postoperative complications. The analysis comprised 648 eyes of 611 patients. The median follow-up was 26.9 months (range, 12-60 months). The most common vitreoretinal pathology was intraocular tumor (53%). The best-corrected Snellen VA improved from 20/192 at baseline to 20/46 at the 12-month follow-up. The most frequent intraoperative complication was capsule tear (3.9%). The most common postoperative adverse events after 3 months of follow-up (mean, 24 months) were vitreous hemorrhage (3.2%) and retinal detachment (1.8%). No patient developed endophthalmitis. Combined phacoemulsification with IOL placement and MIVS is a safe, effective technique to manage a broad range of vitreoretinal diseases in patients with significant cataract.

Indications and Results of Emergency Penetrating Keratoplasty With Simultaneous Cataract Surgery ("Triple-PKP à Chaud").

The purpose of this study was to analyze the indications and clinical results of emergency penetrating keratoplasty with simultaneous cataract surgery ("Triple-PKP à chaud"). This study included all subjects who underwent Triple-PKP à chaud between 2006 and 2020 at the Department of Ophthalmology, Saarland University Medical Center, Homburg/Saar in Germany. Data obtained from patient records were retrospectively analyzed. Triple-PKP à chaud was successfully performed in 27 of 29 eyes with a mean age of 66.0 ± 19.9 years. Previous surgery was performed in 20 eyes (69.0%), most frequently amniotic membrane transplantation in 11 eyes (37.9%) and previous keratoplasty in 9 eyes (31.0%). The most common indication was infectious keratitis (62.1%). In 27 subjects (93.1%), capsulorhexis was performed using the open-sky technique. The most frequent intraoperative complication was positive vitreous pressure (24.1%). In 2 eyes (6.9%), no intraocular lens implantation was performed because of posterior capsule rupture. The preoperative uncorrected visual acuity improved from 2.2 ± 0.6 logMAR (range = 3.0-0.7 logMAR) to 1.3 ± 0.7 logMAR (range = 3.0-0.18 logMAR) postoperatively ( P < 0.001). Common postoperative complications were suture loosening (44.4%) and corneal epithelial defects (33.3%). Repeat keratoplasty was necessary in 14 eyes (51.9%), including 9 eyes (64.2%) within 12 months postoperatively. The mean graft survival was 12.2 ± 17.9 months (range = 1-69 mo). Triple-PKP is also feasible in emergency conditions. Nevertheless, the surgery is associated with an increased risk of intraoperative and postoperative complications. Combined surgery should, therefore, only be performed in severely diseased eyes with progressed stage of cataract.

Treatment of sinus membrane perforations during sinus lift surgeries using leukocyte and platelet-rich fibrin: A report of three cases

Schneiderian membrane (SM) perforation is the most frequent intraoperative complication during sinus lifts, which can lead to implant failure or delayed implant treatment. This article aims to show the results of using leukocyte and platelet-rich fibrin (L-PRF) in the treatment of perforations occurring during sinus lifts with a lateral window approach. Three patients (n = 5 implants) with a mean ± SD age of 57.67 ± 12.12 years were included, in whom perforations of the SM of 3-5 mm and >5 mm occurred. The mean ± SD preoperative bone height was 4.42 ± 2.96 and, at 6 months it was 9.58 ± 2.41 (P < 0.05). All implants had a 100% survival rate at 6-24 months. At the split-mouth, the mean ± SD baseline height was 5.05 ± 2.99 mm in repaired SM versus 2.92 ± 1.01 in those without any complications (P > 0.05). At 6 months, mean ± SD gains were 10.09 ± 2.44 mm versus 7.73 ± 0.90 mm, respectively, (P > 0.05). L-PRF simplifies SM repair, reducing the need for high surgical experience and/or skills. Although there are no significant differences between repaired and intact SM, at the radiological level, greater bone compactness and maturation were observed in the latter, which may be associated with the presence of air bubbles caused by anaerobic bacterial activity in repaired SM. The use of L-PRF greatly simplifies the resolution of SM perforations during sinus lift surgeries, reducing treatment times, and providing predictable results. Being of autologous origin, it accelerates and enhances healing, eliminating the possibility of autoimmune rejection reactions.

Clearance of Bone Substitute in Gel Form Accidentally Dispersed into the Sinus Cavity during Transcrestal Maxillary Sinus Floor Elevation: Two-Case Report

Sinus membrane perforation is the most frequent intraoperative complication occurring during maxillary sinus floor elevation. Although numerous techniques for perforation management are present, grafting material dissemination may still occur, representing a potential trigger factor leading to acute or chronic sinusitis. This case report describes two cases of xenogeneic bone substitute in gel form accidentally dispersed into the sinus cavity during maxillary sinus floor elevation with a transcrestal approach. In both cases, immediately postoperative radiographic imaging showed an important amount of gel graft dislodged into the sinus cavity as a consequence of hidden perforations that remained undetected during surgery. Patients were monitored for 6 months after surgery and reported no signs or symptoms related to possible sinus disease. Control radiographs showed no sinus membrane hypertrophy and/or presence of residual disseminated gel, confirming complete clearance of the accidentally dispersed graft through the ostiomeatal complex. In order to minimize postoperative complications, bone substitutes in gel form could represent an interesting alternative to granular grafts for their easier clearance from the maxillary sinus cavity in case of accidental dissemination during sinus augmentation procedures.

Intraoperative complications during laparoscopic total mesorectal excision

Intraoperative complication during laparoscopic mesorectal excision for rectal cancer is a common complication occurring in 11% to 15% of the cases. They are probably underestimated because not systematically reported. The most frequent intraoperative complications are hemorrhage (3-7%), tumor perforation (1-4%), bowel injury (1-3%), ureter injury (1%), urogenital injury (2%), other organ injury (<1%), and anastomotic complications (1%). The mechanisms, management and prevention of vascular port injury, inferior mesenteric artery bleeding, small bowel and colon perforation, ureteral and urethral injury, pelvic nerve damage, tumor perforation and anastomotic failure are described. This review underlines the necessity to prevent intraoperative complication to avoid operative death and severe side-effects.

Salvaging Pull-Out Strength in a Previously Stripped Screw Site: A Comparison of Three Rescue Techniques

Screw stripping during bone fixation is a common occurrence during operations that results in decreased holding capacity and bone healing. We aimed to evaluate the rescue of the stripped screw site using screws of different dimensions. Five screw configurations were tested on cadaveric specimens for pull-out strength (POS). The configurations included a control screw tightened without stripping, a configuration voluntarily stripped and left in place, and three more configurations in which the stripped screws were replaced by a different screw with either increased overall length, diameter, or thread length. Each configuration was tested five times, with each screw tested once. The POS of the control screw, measured to be 153.6 ± 27 N, was higher than the POS measured after stripping and leaving the screw in place (57.1 ± 18 N, p = 0.001). The replacement of the stripped screw resulted in a POS of 158.4 ± 64 N for the screw of larger diameter, while the screws of the same diameter but increased length or those with extended thread length yielded POS values of 138.4 ± 42 and 185.7 ± 48 N, respectively. Screw stripping is a frequent intraoperative complication that, according to our findings, cannot be addressed by leaving the screw in place. The holding capacity of a stripped screw implanted in cancellous bone can successfully be restored with a different screw of either larger diameter, longer length, or extended thread length.

Implant removal of osteosynthesis. Results of a survey among Spanish orthopaedic surgeons

IntroductionThe indications on extraction of osteosynthesis material (EMO) are not well defined in the current literature deriving in relative indications, depending on experiences, customs or patient's request. The aim of this article is to assess the beliefs, indications, usual practice and perceived complications of surgeons in Spain regarding OME. MethodsWe conducted a questionnaire of 44 questions covering general demographics, general and subjective opinion on implant removal, specific attitudes by implant type and anatomical location, and personal habits. Results164 questionnaires were received. The most frequent indications are patellar and olecranon locks and elastic nails in children. 56% remove the implant at the patient's request, 31% always remove it in children, 28% do it in asymptomatic patients to avoid possible surgical problems, 14% to avoid a possible peri-implant fracture and 9% by simple preference. The most frequent intraoperative complications are surgery longer than expected, bone growth over the implant, rounded screw head core, cold fusion, difficulty in finding the implant and impossibility to remove part of the implant. The most frequent postoperative complication was persistence of symptoms 39.8%. ConclusionThe results provide information to advise the patient regarding the expected clinical outcome and intra and postoperative complications. The surgeon should cautiously indicate extraction in the asymptomatic patient given the high rate of complications.

Role of Pterygopalatine Fossa Block on Intra-Operative Heart Rate and Blood Pressure During Endoscopic Sinus Surgery at a Tertiary Care Centre

Background: Functional Endoscopic Sinus Surgery (FESS) is a physiological and also well accepted surgical treatment for chronic sinus disease that is unresponsive to medical treatment. The most frequent intraoperative complication is bleeding. Various methods are being tried to reduce the bleeding during FESS. But, none of these methods consistently provide the desirable bloodless field for the surgeons. Blockage of Pterygopalatine Fossa (PPF) through the greater palatine foramen is an alternative approach to reduce blood loss during ESS, which is an easy procedure, associated with little complication. Pterygopalatine Fossa Block (PPFB) along with general anaesthesia is effective in patients undergoing FESS surgery. Aims and Objectives: To assess the effect on and the difference in heart rate and blood pressure after pterygopalatine fossa block during FESS surgery. Materials and Methodology: 25 Patients with bilateral nasal pathology undergoing FESS were selected from ENT wards after a written informed consent. The PPFB was done only on one side, while the opposite nostril acted as control, thus each case acted as their own control. Various vital parameters like – heart rate (HR), blood pressure [(BP) systolic and diastolic] were calculated every 15 mins and their average noted. Surgery on the first side was completed and then followed by surgery on the second side. Applying paired-t Test, results were obtained. Results and Conclusion: There was a significant fall in heart rate and blood pressure. There was a positive correlation between these factors. "p value” was found to be highly significant in both the parameters tested. Pterygopalatine fossa block is an effective adjunct to general anaesthesia for controlling heart rate and blood pressure during FESS surgery.

Complications of robot-assisted and laparoscopic partial nephrectomy

Objective: to analyze complications after laparoscopic and robotic-assisted partial nephrectomy.Materials and methods. In our study was included 246 cases. Intra- and postoperative complications were studied after nephron-sparring surgery. The laparoscopic approach was used in 68 (27.3 %) cases, the robot-assisted - in 178 (71.5 %) cases. Intraoperative complications were assessed according to the Rosenthal classification, postoperative complications - according to the Clavien-Dindo classification.Results. The overall incidence of intraoperative complications was 12.6 %. The most frequent intraoperative complication was bleeding that did not require blood transfusion (grade I) - 5.69 % (laparoscopic approach - in 3 (4.41 %) cases, robot-assisted approach - in 11 (6,18 %) cases). Bleeding requiring blood transfusion and injuries of internal organs, which were restored intraoperatively (grade II), were recorded in laparoscopic and robot-assisted approaches in 4.41 % and 2.25 % of cases, respectively. Complications leading to the loss of organ (nephrectomy, splenectomy) were observed in 2.94 % and 4.49 % of cases, respectively. Intraoperative deaths (grade IV) were not registered.The incidence of postoperative complications was 18.29 %. Minor complications (Clavien-Dindo ≤II) were detected in 16 (6.5 %) patients (laparoscopic approach - 7.35 %, robot-assisted approach - 6.18 %). Serious complications (Clavien-Dindo ≥III) were detected in 29 (11.79 %) cases (with laparoscopic approach - 14.71 %, robot-assisted - 10.67 %). In the group of tumors with the RENAL index 4-6, the incidence of postoperative complications was 14.7 % with the laparoscopic approach, and 7.1 % with the robot-assisted approach; in the RENAL 7-9 group - 21.9 % and 13.0 %, respectively. In the group of tumors of high complexity (RENAL 10-12), only the robot-assisted approach was used, the incidence of postoperative complications was 22.0 %.Conclusion. Partial nephrectomy for kidney tumors is an effective and safe surgical technique. The incidence of complications when using the laparoscopic approach is higher than when using the robot-assisted technique in groups of tumors of simple and medium complexity. For tumors of high complexity, robot-assisted approach is a priority. The largest number of serious complications is observed with partial nephrectomy with complex tumors.

Methods of prevention and elimination of the most frequent intraoperative and postoperative complications in the surgical treatment of pulmonary and pleural tuberculosis using video-assisted surgical interventions

Objective — to identify and analyze methods of prevention and elimination of the most common intraoperative and postoperative complications in the surgical treatment of pulmonary tuberculosis and pleura using VATS.&#x0D; Materials and methods. In the Department of Thoracic Surgery and Invasive Diagnostic Methods of the National Institute of Phthisiology and Pulmonology named after F.G. Yanovsky NAMS of Ukraine for the period from 2008 to 2019 performed 169 VATS operations on patients with tuberculosis surgery, of which: 130 (79.3 ± 3.2) % VATS lung resections; 35 (20.7 ± 3.1) % VATS pleurectomy with decortication (PE with DC) of the lung; 4 (2.4 ± 1.2) % of patients underwent other VATS interventions.&#x0D; Results and discussions. The level of intraoperative complications among all 169 operated patients was recorded in 9 (5.3 %) cases. Postoperative complications were detected in 29 (17.1 %) patients.Methods of prevention of complications in VATS are the selection of patients at the preoperative stage, correction of hemostasis, safe areas of thoracoport and minitracotomy, lymph dissection, separate treatment of lung root elements, conversion to thoracotomy.&#x0D; Conclusions. VATS interventions are minimally invasive, effective and convenient methods of surgical treatment of patients with pulmonary and pleural tuberculosis. Adequate assessment of the possibility of performing VATS, methods of prevention of complications and their timely application provides a predictable course of the postoperative period and reduces the number of complications. Diagnosis of complications and timely use of various methods of their elimination allows you to effectively and reliably apply medical manipulations to resolve both intra­ and postoperative complications in this type of surgery. Understanding and using methods of prevention and elimination of complications, allows to determine the correct tactics of operation and management of the postoperative period.

Anesthetic protocol for right ventricular dysfunction management in heart transplantation: systematic review, development and validation

BackgroundRight Ventricular Dysfunction (RVD) is the most frequent intraoperative hemodynamic complication in Heart Transplantation (HTx). RVD occurs in 0.04–1.0% of cardiac surgeries with cardiotomy and in 20–50% of HTx, with mortality up to 75%. No consensus has been established for how anesthesiologists should manage RVD, with management methods many times remaining unvalidated.MethodsWe conducted a systematic review, following PRISMA guidelines, to create an anesthetic protocol to manage RVD in HTx, using databases that include PubMed and Embase, until September 2018 based on inclusion and exclusion criteria. The articles screening for the systematic review were done two independent reviewers, in case of discrepancy, we consulted a third independent reviewer. Based on the systematic review, the anesthetic protocol was developed. The instrument selected to perform the validation of the protocol was AGREE II, for this purpose expert anesthetists were recruited to do this process. The minimum arbitration score for domains validation cutoff of AGREE II is arbitered to 70%. This study was registered at PROSPERO (115600).ResultsIn the systematic review, 152 articles were included. We present the protocol in a flowchart with six steps based on goal-directed therapy, invasive monitoring, and transesophageal echocardiogram. Six experts judged the protocol and validated it.ConclusionThe protocol has been validated by experts and new studies are needed to assess its applicability and potential benefits on major endpoints.

Perioperative complications of laparoscopic cholecystectomy: a cross-sectional observational study

Background: Laparoscopic cholecystectomy (LC) has now become the gold standard in treatment of benign gall bladder disease. The intraoperative and immediate postoperative complication cannot be disregarded and remain of concern. The study aims to evaluate the perioperative complications of LC in patients undergoing the surgery.Methods: A total of 100 patients were included in this prospective analytical study from a June 2017 to September 2019. They were adequately evaluated and underwent LC in General surgery department of Geetanjali Medical College and Hospital, Udaipur. The relevant clinical details of all the patients were recorded and analysed.Results: Among the patients who underwent LC, majority were females. In case of 86 patients, LC was done due to chronic calculous cholecystitis. The conversion rate from laparoscopic to open was 6%. The most frequent intraoperative complication was trocar site bleeding and liver bed injury, 7%, followed by bile leakage from gallbladder 6%, bleeding from calots triangle in 4% and spilled gallstones in 2% cases. There was no case of injury to common bile duct, bowel injury or major vascular injury. Amongst the post-operative complications, wound infection was in 1% case. No perioperative mortality was present. The overall rate of complication was 18%.Conclusions: LC is a safe and effective procedure in almost all patients presenting with symptomatic gallbladder disease and remains one of the most frequently performed laparoscopic operations. It has a low rate of mortality and morbidity making this operation a safe procedure with favourable results.

Emergency hysterectomy in a tertiary care hospital: indications, surgical outcomes and challenges: a 2-year retrospective descriptive cross-sectional study.

Introductionemergency hysterectomy (EH) remains a life-saving procedure in cases of life-threatening obstetric hemorrhage and other gynaecological emergencies. We aim to determine the indications, surgical outcomes and challenges of EH in our tertiary centre.Methodsan ethically approved retrospective descriptive cross-sectional study on all EHs performed at a tertiary hospital during the period of 1st January 2018 to 31st December 2019 was conducted. Medical records of eligible patients were retrieved, reviewed and analysed using frequencies and percentages and then summarized in tables.Resultsthere were 146 EHs over the two year period. The age of participants ranged from 19 to 59 years, with a mean of 34.3 years (SD = 6.06). SD: standard deviation.The main indication for EH was primary postpartum haemorrhage (PPH): 73.28% (n = 110/146). The other indications were uterine perforation with necrosis: 8.9% (n = 13/146), secondary postpartum haemorrhage: 4.8% (n = 7/146), choriocarcinoma and pelvic abscess: 2.74% (n = 4/146) each and broad ligament haematoma: 2.06% (n = 3/146). There were 3.42% (n = 5/146) which were classified as ‘others **’: two cases of ovarian cyst torsion; one case of placental site tumour; one case of incomplete septic abortion; one case of bulky multinodular fibroid uterus with severe unremitting lower abdominal pain.The most common indication for the subgroup of hysterectomy due to PPH was uterine atony 54.20% (n = 60/110), followed by ruptured uterus20.56% (n = 23/110) and then, morbidly adherent placenta 14.95% (n = 16/110). Placenta accreta constituted 62.5% (n = 10/16) of the morbidly adherent placenta.There were 91.78% (n=134/146) total abdominal hysterectomies and 8.22% (n = 12/146) subtotalhysterectomies. About eighty percent 79.45% (n = 116/146) of the surgeries required general anaesthesia, 15.07% (n = 22/146) required regional anaesthesia whilst 5.48% (n = 8/146) were started as regional anaesthesia but were converted to general anaesthesia.There were no associated intraoperative complications in 96.60% (141/146) of the cases. The most frequent intraoperative complications included bowel injury 2.04% (3/146), bladder injury 0.68% (1/146) and maternal death 0.68% (1/146).Twoof the three bowel injuries required bowel resection and anastomosis. Most of the surgeries 89.73% (n = 131/146) were performed by skilled doctors above the level of a Specialist. Major challenges faced include delayed referral of patients to the tertiary centre for prompt management and lack of quick access to blood products.Conclusionemergency hysterectomy is performed in women who are relatively young with primary postpartum haemorrhage as the commonest indication but there are other non-obstetric indications for this emergency surgery. Though a challenging procedure, it is safe in the hands of a skilled surgical team.

Retroperitoneal tumors and congenital variations in vascular anatomy of retroperitoneal great vessels

Background/objectivesVariations in vascular anatomy (VIVAs) of the retroperitoneal great vessels are uncommon but can potentially complicate surgical procedures and negatively affect treatment outcomes, yet their incidence and clinical impact are poorly studied. We sought to assess the incidence and clinical impact of VIVAs of retroperitoneal great vessels in patients with retroperitoneal tumors. MethodsWe retrospectively analyzed imaging, surgical, treatment and survival data of all pediatric patients with retroperitoneal tumors who underwent resection between January 2007 and October 2016, comparing preoperative scans with corresponding intraoperative observations, and subsequent surgical outcomes. ResultsAmong 66 children with renal, adrenal and paravertebral tumors, 6 (9%) had retroperitoneal VIVAs. Retroperitoneal VIVAs were present only with right-sided tumors and significantly associated with more frequent intraoperative complications (P = 0.013). While the presence of retroperitoneal VIVAs was not directly associated with survival outcomes, relapse was more frequent in patients with VIVAs (33%) than those without (18.3%, P = 0.378), and relapse was also associated with lower overall and event-free survival (P < 0.001). ConclusionsVIVAs of retroperitoneal great vessels occurred in 9% of our patients with retroperitoneal tumors. Retroperitoneal VIVAs were associated with higher rates of intraoperative complications and disease relapse but was not directly related to survival outcomes. Type of Study: Retrospective review study. Level of evidenceLevel III Retrospective comparative study.

Laparoscopic management of symptomatic gallbladder stump calculi

Aim: The aim of the present study was to evaluate the safety of laparoscopic completion cholecystectomy in patients with symptomatic gallbladder stump calculi. Materials and Methods: Ours was a prospective study conducted in three peripheral hospitals over a period of 6 years. All the patients undergoing elective laparoscopic cholecystectomy during this period were enrolled in the study. The outcomes of laparoscopic completion cholecystectomy in patients with gallbladder stump calculi were compared to those undergoing primary laparoscopic cholecystectomy with regards to perioperative morbidity and mortality. Results: A total of 3127 laparoscopic cholecystectomies were performed. Out of them, laparoscopic completion cholecystectomy was done in 36 (1.15%) patients. There were 21 males and 15 females in these 36 patients. The operative time and hospital stay were significantly increased in the completion group. None of our patients in the completion group required conversion. Perioperative complications were seen more often in the patients posted for completion cholecystectomy (6 [6.67%] vs. 207 [6.69%]; P = 0.0026). Bleeding was the most frequent intraoperative complication seen in the patients undergoing completion cholecystectomy. Conclusion: Laparoscopic completion cholecystectomy, though technically demanding, can be safely done even in a peripheral health setup with acceptable morbidity rate.

The Effect of Pterygopalatine Fossa Block (PPFB) during Endoscopic Sinus Surgery (ESS) on Intraoperative Bleeding: A Randomized Control Trial

Background: Bleeding is the frequent intraoperative complication in most of the surgeries and remains a challenge for the surgeons and anesthesiologists. Major blood loss during FESS is rare but even a small amount of bleeding disturbs the endoscopic surgery field, increases the likelihood of complications, lengthens the time of surgery and results in incomplete surgery. The greater palatine canal (GPC) local injection is used to limit posterior bleeding during sinus surgery. &#x0D; Objective: To study the effect of pterygopalatine fossa block on intraoperative bleeding and operative field optimization during endoscopic sinus surgery. &#x0D; Methods: Prospective double blind randomized control trial. Thirty six patients were recruited in the study who also acted as their own control. PPFB was done only on one side of the nostril and the side was randomized by the lottery; neither the patient nor the operating surgeons were aware of the laterality. Boezaart score was used to quantify the intra-operative blood loss. &#x0D; Results: Blood loss between block group and non-block group was compared. Patients in block group had more stable hemodynamics with no fluctuations, better visibility of the surgical field and decreased blood loss as compared with non-block group. &#x0D; Conclusion: Greater palatine fossa block is a useful adjunct in patients undergoing endoscopic sinus surgery. It provided more stable hemodynamics, good operative conditions by lowering blood loss.
