HPB SO55 - Utilisation of Telephone Assessment Clinic for booking Laparoscopic Cholecystectomy: Analysis of outcomes and cancellations

Abstract Background Despite extensive efforts to increase productivity after the Covid pandemic, there still remain areas of limited capacity. Face-to-face outpatient clinic provision is yet to return to normal levels, despite significant increases in referrals. Telephone assessment clinics are attractive solutions as they can be performed outside 'standard' operating hours of the hospital and require fewer support staff, giving increased flexibility to consultant and trainee surgeons who perform them. However, it is unclear whether telephone assessment alone is sufficient to book patients onto operating lists. This study aimed to assess the effectiveness of telephone assessment alone when booking patients for laparoscopic cholecystectomy. Method A standardised telephone assessment process was developed which included mandatory information about symptoms, past medical and surgical history and body weight. All patients referred for consideration of cholecystectomy from January 2023 to January 2024 received either a telephone or face-to-face clinic appointment; those who received a telephone appointment were not routinely offered face-to-face assessment unless clinically indicated. Patients were listed for laparoscopic cholecystectomy from either clinic and all operations took place on pooled operating lists. Operative and clinical outcomes were recorded, including cancellations on the day and unexpected anatomy or procedures. Outcomes between telephone and face-to-face appointments were compared. Results Over the study period, 189 patients had a laparoscopic cholecystectomy from an elective clinic source. Other sources included those patients who had presented acutely and were discharged and those on semi-acute lists. 106 patients had a telephone assessment as their only prior engagement with surgical services prior to surgery. Of these patients, there was one cancellation on the day (due to absence of symptoms between clinic assessment and date of surgery). Nine patients required cholangiography which had not been initially booked. In contrast, three patients who had had face-to-face assessment were cancelled on the day. Conclusion Telephone assessment alone is sufficient to book patients onto an elective theatre list for laparoscopic cholecystectomy, with no adverse impact on cancellations and theatre utilisation. To ensure low cancellation rates and safe surgery, senior decision making is required for telephone assessment clinics (in this study, all appointments were carried out by consultant surgeons) and a standardised proforma to ensure all relevant information is recorded. The low rate of cancellations was maintained even though a 'pooled' operating list is utilised in our hospital. Telephone assessment clinics for first appointments are safe and effective and could help in reducing overall waiting times.

Impact of Obstructive Sleep Apnea on Outcomes after Anterior Cervical Discectomy and Fusion

Study Design. Retrospective Cohort Objective. To evaluate the impact of having a history of Obstructive Sleep Apnea (OSA) in patients undergoing anterior cervical discectomy and fusion (ACDF) on postoperative outcomes. Summary of Background Data. With an aging population and rates of obesity increasing, comorbidities that influence patient safety are increasingly common. One frequently overlooked comorbidity is OSA which affects nearly 24% of the population. Despite its prevalence, the impact of OSA on outcomes following ACDF is poorly understood. Methods. A retrospective analysis of patients >18 years who underwent 1-4 level ACDF at an academic medical center from 2014-2020 was performed. Patient’s age, sex, BMI, CCI, hypertension, diabetes, and levels fused were propensity matched in a 3:1 fashion. Outcomes assessed included inpatient complications, 30 and 90-day ED visits, 30 and 90-day readmissions, reoperations, and one-year PROMs. Results. A total of 344 ACDF patients (86 OSA, 258 No OSA) were included. 30-day ED visits were higher among the OSA compared to the non-OSA group (5.85% vs 0%, P=0.001). Among ED visits, there were 2 patients with pneumonia, 1 with dysphagia, and 1 with extremity weakness, none of which warranted readmission. ED visits equalized in the 30–90-day window. There were no significant differences in inpatient complications, LOS, discharge disposition, readmissions, reoperations, and one-year PROMs. Conclusion. Patients with a history of OSA underwent ACDF without an increased risk of postoperative complications, readmissions, or reoperations and experienced a complication rate much lower than previously suggested by current literature. OSA patients experienced similar improvements in PROMs at 1-year follow-up. Surgeons should counsel OSA patients regarding the increased risk of 30-day ED visits. But overall, patients can expect safe and equivalent outcomes compared to non-OSA patients which lends support for safe outpatient surgery in this population.

Advances in the research of femtosecond laser-assisted lenticule intrastromal keratoplasty for the correction of hyperopia

Lenticule intrastromal keratoplasty (LIKE) was introduced clinically in the 1980s as a refractive surgery. With the advancements of femtosecond laser, LIKE has been significantly revitalized. Currently, femtosecond laser-assisted LIKE has been demonstrated to be a safe and effective surgical procedure to correct hyperopia, but the predictability is still a major limitation. In this article, we review the history, procedures, influencing factors of predictability and challenge of LIKE to provide reference for clinical practice of femtosecond laser-assisted LIKE.

Pediatric cataract surgery in congenital anterior segment dysmorphology: An overview

Abstract The purpose is to highlight the surgical modifications that are undertaken for a safe cataract surgery when associated with anterior segment dysmorphology. Surgical modifications that are undertaken in a case of congenital cataract complicated with congenital anterior segment dysmorphology such as microcornea, congenital corneal opacity, aniridia, anterior and posterior lenticonus of the lens, and persistent fetal vasculature are described. Careful preoperative assessment is crucial to anticipate and plan for intraoperative and postoperative challenges that may arise during cataract surgery in the presence of anterior segment dysmorphology. Surgical adjustments in cataract surgery when associated with anterior segment dysmorphology should be tailored to each individual case and the surgeon’s expertise.

RADT-06. IDENTIFICATION OF NEW RADIATION RESPONSE PREDICTOR GENES FOR GLIOBLASTOMACRUCIAL CONTRIBUTION OF THE LUNATIC FRINGE GENE (LFNG)

Abstract Glioblastoma (GBM) is adults’ most common aggressive primary intracranial tumor. The current standard of care involves maximal safe surgery followed by radiochemotherapy. OBJECTIVE our study was to identify genes that predict response to radiochemotherapy. MATERIALS AND METHODS We collected molecular and clinical data, including primary glioma mRNA expression, from two international online databases - TCGA and CCGA. A total of 76 cases were examined, with 41 patients in the TCGA cohort and 35 in the CCGA cohort. The patients were divided into two groups before assessing the data. Group 1 included patients who were alive at the time of the analysis, and Group 2 included patients who had passed away. Then, we performed a single-center Moroccan transcriptomic study involving 28 cases to assess the impact of the individualized gene in our environment. RESULTS The following genes, namely SRPX, S100A16, LFNG, CD5, CMBL, and TCTN2, are among the top genes co-overexpressed in TCGA and CGGA patients. We conducted a multivariate COX survival test, taking into account known prognostic clinical parameters, and found that the LFNG gene is the only marker of poor prognosis independent of other clinical markers in TCGA and CGGA patients treated with radiotherapy. Our results indicate that patients who overexpress LFNG have elevated IFNg levels and low granzyme B levels, while the levels of perforin and granzyme A remain unaffected by LFNG variation. Furthermore, our results demonstrate positive correlations between LFNG gene expression and four immune checkpoints (PD1, PDL1, CTLA4, and VISTA), but negative correlations only with TIM3. CONCLUSION Our findings suggest that LFNG could serve as a useful biomarker for identifying patients with poor prognosis and that LFNG expression may be associated with specific immune checkpoint expression patterns. These results have important implications for the development of new therapeutic approaches in the treatment of TCGA and CGGA patients.

Comparative analysis of Roux-en-Y cystojejunostomy versus conservative surgical strategies for giant hepatic hydatid cysts: A retrospective study

BackgroundThis retrospective study addressed the challenge of postoperative biliary fistula, a common complication observed after surgical management of giant hepatic hydatid cysts. The primary objective was to compare the efficacy and safety of conservative surgical techniques versus prophylactic Roux-en-Y cystojejunostomy (R-en-Y CJ) in addressing residual cavity. MethodsRetrospective analysis was conducted on patients who underwent surgical intervention for giant hepatic hydatid cysts with cysto-biliary communication from July 2021 to Jan 2024. Preoperative laboratory tests, imaging studies, surgical procedures, and postoperative outcomes were reviewed from medical records. Results32 patients who underwent surgery for giant hepatic hydatid cysts were included. There were 19 (59.38%) female patients, with a mean age of cohort was 39.13 years. The patients were divided into two groups with respect to the treatment modality: Group A (n = 14), treated with conservative surgical techniques and R-en-Y CJ, and Group B (n = 18), treated with conservative surgical methods. The overall cavity-related complications occurred in 9/18 (50%) in Group B, whereas 2/14 patients (14.29%) in Group A during the follow-up period (p < 0.05). ConclusionR-en-Y CJ is an effective and safe surgical procedure for tackling residual cavities in giant hepatic hydatid cysts with cysto-biliary communication.

New criteria for preoperative liver function assessment with safety margins to avoid postoperative mortality during liver resection for hilar cholangiocarcinoma.

BackgroundDespite recent medical advancements, surgery for hilar cholangiocarcinoma is associated with high complication and mortality rates. This may be partly attributed to the absence of established preoperative liver evaluation criteria for safe surgery. This study aimed to propose a reliable indicator for safe and well-planned management of major hepatectomy with extrahepatic bile duct resection. MethodsWe included 150 patients who underwent major hepatectomy with extrahepatic bile duct resection between 2013 and 2021 in Japan. The risk factors for post-hepatectomy liver failure (PHLF) were retrospectively analyzed. ResultsPHLF was observed in 24 (16.0%) patients who underwent major hepatectomy with extrahepatic bile duct resection. In the multivariate analysis, the identified risk factors for PHLF were the ratio of future remnant liver volume to total liver volume (FRLV/TLV) ≤ 42% and indocyanine green clearance fraction of the future remnant liver (ICGK-F) ≤ 0.07. Patients with these two factors were significantly associated with PHLF compared with those with either one or none of the risk factors (60.0% vs 15.1% and 8.1%, respectively). ConclusionsThe combinational use of ICGK-F and FRLV/TLV is useful for preoperative liver function assessment with a safety margin to avoid PHLF and postoperative mortality in hepatectomy for hilar cholangiocarcinoma.

The WHO surgical safety checklist for cesarean section in an Ethiopian teaching hospital: a prospective cross-sectional study

Background: Implementing the World Health Organization (WHO) Surgical Safety Checklist is crucial for preventing post-surgical complications, including surgical site infections, in low-resource settings such as Ethiopia. The country has the lowest measured rate of safe surgery worldwide, with a significant unmet need for safe and affordable surgical care. The WHO checklist can improve maternal health equity by enhancing surgical and obstetric care safety, ultimately improving maternal outcomes in low- and middle-income countries (LMICs). Objective: This study aimed to assess the compliance, completeness, and determinants of using the WHO’s Surgical Safety Checklist during cesarean section (CS). Methods: This prospective study was conducted in the Obstetrics and Gynecology Department of a large tertiary hospital in Addis Ababa, Ethiopia. Primary data were collected from observations of clinical interactions in the obstetrics operating room (OR) during CSs. The rates of performing the checklist and completing each section were analyzed. Results: Of 250 observed CSs, 26.4% were elective, and 73.6% were emergency procedures. Patient ages ranged from 18 to 45 years, with a median age of 28. The overall compliance rate for the WHO surgical safety checklist was 98%, with 100% compliance for elective procedures and 97.2% for emergency procedures. The completeness rates for sign-in, time-out, and sign-out were 80.1%, 66.4%, and 45.3%, respectively. Conclusion: The study revealed high compliance but low completeness rates for the surgical safety checklist during CS. A noticeable distinction was observed, with elective procedures exhibiting superior compliance and completeness rates compared to emergency procedures. This could be attributed to the sense of urgency and limitations in available time.

Comparison of the MIPPO technique and the modified Stoppa approach in the treatment of unstable anterior pelvic ring injuries: a retrospective cohort study

BackgroundAnterior pelvic ring injuries have gradually become common. Using a minimally invasive technique to treat this injury may be feasible if the reduction and stability can be effectively achieved. We describe a percutaneous technique, minimally invasive percutaneous plate osteosynthesis (MIPPO), to fixate the anterior pelvis via establishing a subperiosteal tunnel between two limited incisions over the iliac crest(s) and pubic ramus in this research.MethodsA retrospective cohort study comparing the MIPPO technique (n = 60) versus the modified Stoppa approach (n = 53) for anterior pelvic ring injuries with posterior ring instability was performed from September 2016 to January 2023. The relative surgery variables, follow-up function evaluation, and complications were compared in two groups. The reduction quality of fracture was assessed according to the Matta criterion, and the functional score was evaluated using the Majeed score.ResultsAll patients completed follow-up, with an average interval of 39.90 ± 17.53 months (range 12–78). In the MIPPO technique group, the surgery interval and blood losses were lower compared to the modified Stoppa approach group (P<0.05). The mean procedure times and intraoperative blood losses were 69.56 ± 14.04 min/side (range 50–110) and 156.23 ± 49.75 mL/side (range 90–250) for unilateral anterior ring MIPPO fixation separately. All patients got a satisfactory reduction of the fracture. In the follow-up, earlier ambulation, shorter postoperative hospital stays, and lower complication rates were observed for patients using the MIPPO technique compared to the modified Stoppa approach (P<0.05). However, there is no statistical difference in these indicators including fracture union interval, full load time, the Majeed score, patient satisfaction level, and return to pre-injured work rate between the two groups.ConclusionThis clinical experience gives support for the use of the MIPPO technique to stabilize the anterior pelvis. This minimally invasive technique was an effective and safe surgery method and could obtain satisfactory function results, particularly fitting to part of patients with resistance using the modified Stoppa approach.

Bilateral total knee arthroplasty-analysis of risk factors for blood loss and blood transfusion

Background: Total knee arthroplasty in general is a safe and successful surgical procedure for end stage arthritis of the knee joint to relieve pain, correct the deformity and restore function in the joint. However, it is often associated with significant blood loss. In such cases, blood transfusion is not uncommon. Methods: 100 patients who underwent simultaneous bilateral TKA from April 2022 to December 2022 at Sant Parmanand Hospital, New Delhi were taken up for the study. Results: In this study among 100 patients who underwent simultaneous bilateral total knee replacement, 9% of the cases required blood transfusion. Preoperative haemoglobin (&lt;12.64 gm/dl) continues to be a predictor in blood transfusions. A haemoglobin level of less than 10.34 gm/dl preoperatively, a postoperative haemoglobin day 1 level of less than 8.56gm/dl and a postoperative day 3 level of less than 7.49 gm/dl increases the necessity for blood transfusion in simultaneously performed bilateral TKAs. Conclusions: Asthma, Diabetes mellitus and patients on blood thinners are three major comorbidities than can cause increased blood loss. Age, gender, BMI and comorbidities are not related to the need for blood transfusion. Patients on blood thinners are at an increased risk for blood transfusion if they have a lower preoperative haemoglobin. Checking haemoglobin values on postoperative day 1 and day 3 are significant in terms of the need for blood transfusion.

Intraoperative neuromonitoring of visual evoked potentials in a pregnant patient with meningioma: a case report

BackgroundMeningioma in the parasellar region may lead to visual impairment, so intraoperative neurological monitoring is essential for enucleation surgery. However, intraoperative neurological monitoring in pregnant women is challenging, as the anesthesia management must consider the effects and risks to the fetus. Remimazolam is a newly introduced intravenous anesthetic that has little effect on blood pressure. However, the effects of remimazolam on intraoperative neuromonitoring are little known. We treated a pregnant patient with parasellar meningioma who developed visual impairment, using remimazolam for anesthesia and intraoperative neurophysiological monitoring of the visual evoked potential.Case presentationA 34-year-old woman who was 20 weeks pregnant presented with visual acuity disturbances. Neuroimaging demonstrated a parasellar meningioma, and rapid tumor growth and worsening of symptoms subsequently occurred. Craniotomy for tumor removal was performed under anesthesia with remimazolam, which allowed monitoring of the visual evoked potentials. Her visual acuity was restored postoperatively, and no adverse events occurred in the fetus.ConclusionOur experience with intraoperative neuromonitoring of a pregnant woman in the third trimester showed that anesthesia with remimazolam allows safe brain surgery combined with intraoperative visual evoked potential monitoring. Further research is needed to determine the effects of remimazolam on the fetus, as well as the safe dosage and duration of exposure.

Comparative Analysis of the Safety and Feasibility of Laparoscopic Versus Open Segment 7 Hepatectomy.

Laparoscopic hepatectomy has been widely accepted owing to its advantages as a minimally invasive surgery; however, laparoscopic segment 7 (S7) hepatectomy (LSH) has been rarely reported. We aimed to explore the safety and feasibility of LSH by comparing it with open surgical approaches. Twenty-nine patients who underwent S7 hepatectomy between January 2016 and January 2023 were enrolled in this study. The patients' characteristics, intraoperative details, and postoperative outcomes were compared between the 2 groups. No significant differences were observed in the preoperative data. The patients who underwent LSH had significantly shorter hospital stays (P=0.016) but longer operative times (P=0.034) than those who underwent open S7 hepatectomy. No significant differences in blood loss (P=0.614), transfusion (P=0.316), hospital expenses (P=0.391), surgical margin (P=0.442), rate of other complications, postoperative white blood cell count, and alanine aminotransferase and aspartate aminotransferase levels were noted between the 2 groups (P>0.05). For hepatocellular carcinoma, the results showed no differences in either disease-free survival (P=0.432) or overall survival (P=0.923) between the 2 groups. LSH is a safe and feasible surgical procedure that is efficient from an oncological point of view. It may be the preferred technique for lesions in the S7 of the liver.

Morbidity related to major lung thoracoscopic resections in children.

In pediatric thoracic surgery, reported predictors for increased risk are symptoms and active/previous infections (RAP). We investigated the adverse events related to Video-Assisted Thoracic Surgery (VATS) in pediatric patients when considering RAP predictors. A retrospective analysis of pediatric VATS major lung resections in 2008-2021 was conducted at three institutions. We employed the pediatric surgical risk calculator to define patients' preoperative predicted risk (PredR). Postoperative complications were classified according to the Thoracic Morbidity & Mortality (TM&M) system. The observed TM&M rate (ObsR) and the PredR were compared. A subgroup analysis by RAP predictors was conducted. 37 patients (54% female) were included. Mean age and weight were 5.8 years and 22.8 kg. 56.7% had respiratory symptoms, 38.9% active infection and 59.5% history of infections (RAP subpopulations). VATS procedures were lobectomy (n=32), segmentectomy (n=3), bilobectomy (n=1) and pneumonectomy (n=1). The conversion rate was 5.4%. The mean PredR was of 4.43% (±1.8) and the overall ObsR was 45.94% with a median severity of II (I-III). This difference was significant and a higher PredR was not associated with complications development. PredR does not show association among the RAP vs non-RAP group. ObsR showed positive association with RAP, even if it reached statistical significance only for "respiratory symptoms" risk factor. ObsR reflected the number of bronchiectasis patients in our series (n=9), aligning with the hypothesis of "earlier and safer surgery". The risk calculator underestimates VATS morbidity. Multicentre studies will clarify the correlation between inflammation and surgical adverse events.

Sociodemographic Influence on the Management of Orofacial Cleft in Urban and Rural Indonesia.

To explore the social experiences of orofacial cleft patients and contextualize sociodemographic influence on management disparities in rural and urban areas of Indonesia. This study explores patients' lives in two demographical settings in South Sulawesi Province, Makassar and Selayar Islands Regency. It employs ethnography, including open-ended interviews and observations of patients, their neighborhoods, schools, and workplaces. Secondary data from the two regencies and South Sulawesi province are employed to demonstrate demographic disparities in patient care between urban and rural areas. Thematic content analysis was performed according to socio-demographical differences and networks involved in the management. This study engaged a diverse group of participants, including patients, family caregivers, medical team members, and patient peers (n = 40), primarily from middle to low-income families. Parents in both regions had limited knowledge about treatment modalities, which resulted in concerns regarding the safety of surgical procedures and the postponement of mandatory surgeries. In rural areas, patients faced significant financial burdens when referred to Makassar. In contrast to parents in Selayar, parents in Makassar prioritized more social interaction to ensure that their children attended school, college, and work. Patients in both settings reported facing various obstacles at different stages of their lives. Sociodemographic conditions contribute to disparities in treatment, social positioning, and self-perception. Promoting education about the safety of medical and rural surgical procedures is vital. Involving patients in public activities and providing support from family caregivers is paramount to nurturing patients' optimistic outlooks.

Analysis of Failed Posterior Fossa Decompression and an Effective Revision Surgery in Patients with Basilar Invagination and Atlantoaxial Dislocation.

The objective of this study was to analyze failed posterior fossa decompression (PFD) in patients with basilar invagination and atlantoaxial dislocation (BI-AAD). Revision surgery in these patients is challenging and has been rarely reported. In addition, the anatomical variations of the vertebral artery increase the risk of revision surgery. Here, we introduce the implementation of a new type of one-stage posterior revision surgery, whose difficulties and effects are summarized. A total of 21 patients with BI-AAD who underwent PFD were retrospectively analyzed in our center from November 2017 to April 2021. The revision surgery in all patients was performed through the posterior approach. The Japanese Orthopaedic Association (JOA) score and the Short Term 12 (SF-12) score were employed to evaluate the clinical symptoms and health status. The distance from the tip of the odontoid to Chamberlain's line (DCL), the atlantodental interval (ADI), the clivus-canal angle (CCA), the diameter of the subarachnoid space (DSS), and the craniovertebral junction triangular area (CTA) were assessed radiographically. The pre- and postoperative results were compared by paired t test. The data of 21 consecutive patients were reviewed, with an average follow-up period of 28 ± 14 months. Postoperative imaging showed effectively reduced compression of BI-AAD. No implant failure or neurovascular injury occurred. Eleven patients had vertebral artery abnormalities, but none had vertebral artery injury. All patients had evidence of bone fusion on the CT scan images within a 12-month follow-up period. The JOA and SF-12 scores were significantly improved 1 year postoperatively (p < 0.001). Posterior surgery using the technique of interarticular distraction, fusion with cage grafting, and fixation is a safe and effective revision surgery to treat patients with basilar invagination and atlantoaxial dislocation who failed PFD, which will result in good outcome.

Efficacy and safety of endoscopic subserosal dissection treatment for gastrointetinal submucosal tumors in the upper gastrointestinal tract

ObjectiveTo investigate the safety and efficacy of endoscopic subserosal dissection for patients with submucosal tumors in the upper gastrointestinal tract.MethodsThis retrospective single-center study included 16 patients who underwent ESSD. All patients were enrolled from July 2018 to Dec 2021. Parameters such as demographics, size, resection margin, complications, pathological features, procedure time and follow-up were investigated and analyzed.ResultsOur study achieved 100% en bloc resection and 100% R0 resection. The most common location was the corpus with a mean tumor size of 2.78 ± 1.56 cm. The mean age, procedure time, were 53.4 ± 10.3 years, 85.31 ± 46.64 min respectively. Acocording to National Institutes of Health classification, 7 (13, 53.85%), 5 (13, 38.46%) ,and 1 (13, 7.69%) objects belonged to the very low, low, and intermediate classification, respectively. Immunohistochemistry results showed a 100% positive rate of CD34, DOG-1, CD117, and Ki67. A mean follow-up of 9.3 ± 2.5 months showed no recurrence or metastasis.ConclusionsESSD is effective and safe surgical procedure for curative removal of gastrointestinal submucosal tumors in the upper gastrointestinal tract, and it can be preferred for patients with no metastasis.

Analysis of emergent reoperations after bariatric surgery: an important metric for safe same-day surgery

BackgroundEarly reoperation after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) is a severe adverse event that may increase the risk of perioperative mortality if there is a delay in care. However, it is unclear what proportion of reoperations occur within 24 hours of surgery and who is at greater risk, which may impact the safety of performing safe same-day surgery. ObjectivesTo evaluate the incidence of reoperation in the first 24 hours after primary SG and RYGB. SettingMichigan Bariatric Surgery Collaborative, Ann Arbor, Michigan. MethodsUsing a statewide bariatric surgery data registry, patients undergoing primary SG (n = 49,848) and RYGB (n = 11,267) cases were analyzed. Patients who had a subsequent reoperation were identified and reasons for reoperation were compared between those occurring <24 hours versus >24 hours. In addition, patients who underwent a reoperation <24 hours were compared with patients who underwent primary SG or RYGB and did not experience any complications. ResultsThe overall rate of reoperation was .72% for SG and 2.1% for RYGB. Reoperation <24 hours of index procedure was 32.0% after SG and 24.2%, after gastric bypass, with the most common reason being hemorrhage (86.15%% and 55.4% respectively). Older age, hypertension, liver disease, and longer operative times were associated with reoperation <24 hours after SG, whereas longer operative times were associated with reoperation <24 hours after RYGB. Concurrent hiatal hernia repair was not associated with increased risk. ConclusionsReoperation after primary bariatric surgery is rare but occurs within 24 hours in approximately one third of the cases after SG and one quarter of cases after RYGB. Older patients with significant comorbidities are at increased risk and should be considered poor candidates for same-day surgery given the possibility of an early life-threatening event.

Usefulness and Safety of Hybrid Uterine Septal Dissection

Objectives: The objective of this study was to investigate the safety and utility of hybrid uterine septal resection. Materials and Methods: This retrospective cohort trial included 16 patients who underwent hybrid uterine septal resection at Hyogo Medical University Hospital between January 2017 and September 2021. Hysteroscopic uterine septum resection was performed in 16 patients, whereas 5 patients with vaginal septal complications underwent an additional vaginal septectomy under supervision by thin laparoscopy and fluoroscopy. The main outcome measures were pregnancy success rate and procedure safety. Results: The results showed that the median operative time was 77 (46–114) min, and no cases of intraoperative or postoperative adverse events were identified. The postoperative pregnancy rate was 100.0% (7/7) and the live birth rate was 71% (5/7) in women with recurrent pregnancy loss. Among women with infertility, the postoperative pregnancy rate was 55.5% (5/9), and the live birth rate was 20% (1/5). Conclusion: These findings indicate that our hybrid septal resection technique reduces patient burden and ensures safe and reliable surgery, with good results in terms of postoperative complications, pregnancy, and miscarriage rates.
