Does Incision Location Matter? Analysis of Single-Port Cosmesis in Urologic Reconstructive Surgery.

Introduction and Objective: One potential advantage of single-port (SP) robotic surgery compared with multiport (MP) robotic surgery is improved cosmesis. The only studies in urology patients to suggest this finding did not assess differences based on incision site. Our study evaluated SP, MP, incision location, age, gender, and prior abdominal surgery as predictors of cosmesis and scar consciousness for reconstructive procedures. Methods: This is a cohort study using an institutional review board-approved prospective genitourinary reconstruction database. Patients at least 3 months from surgery were emailed and called to complete the Consciousness subsection of the Patient Scar Assessment Questionnaire. Bothersome was defined as a score of 11 or greater. Overall consciousness was scored with a single item as "not conscious" or "conscious." Pearson's chi-squared, Wilcoxon rank sum, Fisher's exact test, and logistic regression were performed to assess how age, gender, prior surgery, and incision location affect cosmesis. Results: There were 111 patients (54 MP, 57 SP), of which 27 were SP umbilical, 14 were SP midline nonumbilical, and 16 were SP lower quadrant. On univariate analysis the periumbilical incision had the lowest consciousness. Age was associated with Bother (p = 0.012) and Consciousness (p = 0.002), whereas gender, prior abdominal surgery, and incision site were not significant. On logistic regression, all SP incisions were less likely to be bothered compared with MP, although only SP umbilical was statistically significant (odds ratio [OR] = 0.08, 95% confidence interval [CI]: 0.01,0.38; p = 0.005). Age was also significant on logistic regression for Bother (OR = 0.96, 95% CI: 0.93,0.99; p = 0.005). Gender and prior abdominal surgery were not associated with Bother or Consciousness. Conclusions: SP periumbilical incisions provide the best outcomes for cosmesis compared with other SP incision sites and MP incisions. This finding should be discussed and taken into account when planning surgical approaches for patients undergoing urinary reconstruction, especially in patients younger than 40 years of age.

A Scoping Review of GLP-1 Receptor Agonists: Are They Associated with Increased Gastric Contents, Regurgitation, and Aspiration Events?

Background: The increased popularity and ubiquitous use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) for the treatment of diabetes, heart failure, and obesity has led to significant concern for increased risk for perioperative aspiration, given their effects on delayed gastric emptying. This concern is highlighted by many major societies that have published varying guidance on the perioperative management of these medications, given limited data. We conducted a scoping review of the available literature regarding the aspiration risk and aspiration/regurgitant events related to GLP-1 RAs. Methods: A librarian-assisted search was performed using five electronic medical databases (PubMed, Embase, and Web of Science Platform Databases, including Web of Science Core Collection, KCI Korean Journal Database, MEDLINE, and Preprint Citation Index) from inception through March 2024 for articles that reported endoscopic, ultrasound, and nasogastric evaluation for increased residual gastric volume retained food contents, as well as incidences of regurgitation and aspiration events. Two reviewers independently screened titles, abstracts, and full text of articles to determine eligibility. Data extraction was performed using customized fields established a priori within a systematic review software system. Results: Of the 3712 citations identified, 24 studies met eligibility criteria. Studies included four prospective, six retrospective, five case series, and nine case reports. The GLP-1 RAs reported in the studies included semaglutide, liraglutide, lixisenatide, dulaglutide, tirzepatide, and exenatide. All studies, except one case report, reported patients with confounding factors for retained gastric contents and aspiration, such as a history of diabetes, cirrhosis, hypothyroidism, psychiatric disorders, gastric reflux, Barrett's esophagus, Parkinson's disease, dysphagia, obstructive sleep apnea, gastric polyps, prior abdominal surgeries, autoimmune diseases, pain, ASA physical status classification, procedural factors (i.e., thyroid surgery associated with risk for nausea, ketamine associated with nausea and secretions), and/or medications associated with delayed gastric emptying (opioids, anticholinergics, antidepressants, beta-blockers, calcium channel blockers, DPP-IV inhibitors, and antacids). Of the eight studies (three prospective and five retrospective) that evaluated residual contents in both GLP-1 users and non-users, seven studies (n = 7/8) reported a significant increase in residual gastric contents in GLP-1 users compared to non-users (19-56% vs. 5-20%). In the three retrospective studies that evaluated for aspiration events, there was no significant difference in aspiration events, with one study reporting aspiration rates of 4.8 cases per 10,000 in GLP-1 RA users compared to 4.6 cases per 10,000 in nonusers and the remaining two studies reporting one aspiration event in the GLP-1 RA user group and none in the non-user group. In one study that evaluated for regurgitation or reflux by esophageal manometry and pH, there was no significant difference in reflux episodes but a reduction in gastric acidity in the GLP-1 RA user group compared to the non-user group. Conclusions: There is significant variability in the findings reported in the studies, and most of these studies include confounding factors that may influence the association between GLP-1 RAs and an increased risk of aspiration and related events. While GLP-1 RAs do increase residual gastric contents in line with their mechanism of action, the currently available data do not suggest a significant increase in aspiration and regurgitation events associated with their use and the withholding of GLP-1 RAs to reduce aspiration and regurgitation events, as is currently recommended by many major societal guidelines. Large randomized controlled trials (RCTs) may be helpful in further elucidating the impact of GLP-1 RAs on perioperative aspiration risk.

Recent advances in peritoneal dialysis catheter placement: the association between method of insertion, operator, and prior abdominal surgery and outcomes.

Peritoneal dialysis (PD) is associated with comparable outcomes to hemodialysis and is much less expensive to provide in most parts of the world. A well functioning PD catheter is required, but complications are frequent, and while there are guidelines for the placement and care of a PD access, they are based on low-quality evidence. Data reporting the outcomes of percutaneous, as compared to surgical pathways for placement of catheters and the role of operator type in determining outcomes are examined. The impact of prior abdominal procedures on patient selection and the prognostic importance of the presence of adhesions at the time of catheter insertion are reviewed. There are conflicting data about the relative merits of percutaneous as compared to surgical placement of catheters that may relate to differences in patient selection, operator experience, or operator volume. Prior abdominal procedures are not associated with worse PD catheter outcomes and likely should not influence patient selection, except in exceptional circumstances. Finally, the presence of adhesions is associated with a higher risk of complications. However, even in the presence of adhesions, the termination of PD therapy and need for re-intervention occurs in <20% of patients.

S4726 Perforated Closed Loop Obstruction Secondary to Adhesion in the Absence of Prior Abdominal Surgery

Application of Indocyanine Green Fluorescence Imaging During Laparoscopic Reoperations of the Biliary Tract Enhances Surgical Precision and Efficiency.

A history of abdominal surgery is considered a contraindication for laparoscopic procedures. However, the advancements in laparoscopic instruments and techniques have facilitated the performance of increasingly intricate operations, even in patients with prior abdominal surgeries. ICG fluorescence imaging technology offers advantages in terms of convenient operation and clearer intraoperative bile duct imaging, as confirmed by numerous international clinical studies on its feasibility and safety. The application of ICG fluorescence imaging technology in repeat laparoscopic biliary surgery, however, lacks sufficient reports. The clinical data of patients who underwent elective reoperation of the biliary tract in our department between January 2020 and June 2022 were retrospectively analyzed. ICG was injected peripherally before the operation, and near-infrared light was used for 3-dimensional imaging of the bile duct during the operation. Altogether, 143 patients were included in this study and divided into the fluorescence and nonfluorescence groups according to the inclusion criteria. Among the 26 patients in the fluorescence group, cholangiography was successfully performed in 24 cases, and the success rate of intraoperative biliary ICG fluorescence imaging was 92.31%. The intraoperative biliary tract identification time was significantly different between the fluorescence and nonfluorescence groups, but no statistical difference was observed in the final operation method, operative time, and intraoperative blood loss between the 2 groups. Although there was no significant difference in the postoperative ventilation rate, incidence of bile leakage, and stone recurrence rate at 6 months postoperatively between the 2 groups (P>0.05), a significant difference in postoperative hospitalization days was observed (P=0.032). The application of ICG fluorescence imaging technology in laparoscopic reoperation of the biliary tract is useful for the early identification of the biliary tract during operation, thereby shortening the operative time and reducing the risk of damage to nonoperative areas. This approach also enhances the visualization of the biliary system and avoids secondary injury intraoperatively due to poor identification of the biliary system. This technique is safe for repeat biliary tract surgery and has a good application prospect.

Catastrophic uterine rupture of an unscarred uterus following motor vehicle rollover – a case report

A 22 year old female at 6 months gestation with no history of prior abdominal surgery or previous uterine procedures presented via air transport after highway motor vehicle rollover. Due to hemodynamic instability, the only preoperative imaging that was able to be obtained was bedside sonography, which confirmed free fluid in the upper quadrants and unfortunately, fetal demise. In the operating room, source of bleeding was noted to be multiple large uterine ruptures. Uterine rupture in trauma in the absence of prior uterine surgery is a rare event and has never been reported in the third trimester, however it should remain in the differential for a pregnant trauma patient presenting with hemodynamic instability.

Outcomes after right-sided colon surgery in Crohn's disease versus cancer.

Surgery for Crohn's disease (CD) is considered to have more complications due to the underlying inflammation, immunosuppression, and malnutrition.We sought to study the outcomes of right-sided colonic resection in patients with CD and patients with cancer at a high-volume tertiary center utilizing a standardized perioperative protocol. This is a retrospective study of outcomes for all patients with CD or patients undergoing ileocolic resection or right hemicolectomy with ileocolic anastomosis at a single institution from 2013 to 2022. Patients were excluded if they simultaneously underwent another procedure or ostomy creation. Data were analyzed using Wilcoxon rank-sum and chi-squared tests for univariate analyses, and logistic and linear regressions for multivariate analyses. In total 141 patients with CD and 589 patients with cancer were included. Patients with CD were significantly younger with lower body mass index and less likely to have comorbidities, including diabetes and hypertension. Patients with CD were less likely to have a smoking history or prior abdominal surgery, but more likely to be on steroids. Both groups had similar rates of laparoscopy, intraoperative complications, and blood loss. Despite the preoperative and intraoperative differences, both patients with CD and patients with cancer had similar lengths of stay (LOS), readmission, reoperation, and mortality rates.None of the surgical outcomes differed significantly between the two groups.On multivariate analysis, CD diagnosis was not associated with reoperation, readmission, mortality, or LOS while controlling for other characteristics. With the use of standardized perioperative protocols, surgery for CD at a high-volume center with expertise in CD can be performed with comparable results to other indications like cancer.

Prospective multicenter study to identify optimal target population for motorized spiral enteroscopy

Motorized spiral enteroscopy (MSE) enhances small bowel exploration, but the optimal target population for this technique is unknown. We aimed to identify the target population for MSE by evaluating its efficacy and safety, as well as detecting predictors of efficacy. A prospective multicenter observational study was conducted at 9 tertiary hospitals in Spain, enrolling patients between June 2020–2022. Analyzed data included demographics, indications for the procedure, exploration time, depth of maximum insertion (DMI), technical success, diagnostic yield, interventional yield, and adverse events (AE) up to 14 days from enteroscopy. Patients with prior gastrointestinal surgery, unsuccessful balloon enteroscopy and small bowel strictures were analyzed. A total of 326 enteroscopies (66.6% oral route) were performed in 294 patients (55.1% males, 65 years ± 21). Prior abdominal surgery was present in 50% of procedures (13.5% gastrointestinal surgery). Lower DMI (162 vs 275 cm, p = 0.037) and diagnostic yield (47.7 vs 67.5%, p = 0.016) were observed in patients with prior gastrointestinal surgery. MSE showed 92.2% technical success and 56.9% diagnostic yield after unsuccessful balloon enteroscopy (n = 51). In suspected small bowel strictures (n = 49), the finding was confirmed in 23 procedures (46.9%). The total AE rate was 10.7% (1.8% classified as major events) with no differences related to prior gastrointestinal/abdominal surgery, unsuccessful enteroscopy, or suspected small bowel strictures. The study demonstrates that MSE has a lower diagnostic yield and DMI in patients with prior gastrointestinal surgery but is feasible after unsuccessful balloon-enteroscopy and in suspected small bowel strictures without safety concerns.

A DIEP Dive into Patient Risk Factors for Hernia and Bulge Development: A Meta-regression.

This meta-regression aims to investigate risk factors for abdominal hernia and bulge in patients undergoing deep inferior epigastric perforator (DIEP) flaps and the effect of prophylactic mesh placement on postoperative complications. A systematic search was conducted in July of 2022 in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Seventy-four studies published between 2000 and 2022 met the inclusion criteria. Sixty-four studies were included in the analysis for bulge and 71 studies were included in the analysis for hernia. Meta-regressions were run on the proportion of patients experiencing hernia or bulge to assess for patient risk factors and the role of prophylactic mesh placement. Proportions were transformed using the Freeman-Tukey double arcsine method. The average rates of hernia and bulge after DIEP flaps were found to be 0.18% and 1.26%, respectively. Increased age (β = 0.0059, p = 0.0117), prior abdominal surgery (β = 0.0008, p = 0.046), and pregnancy history (β = -0.0015, p = 0.0001) were significantly associated with hernia. Active smoking (β = 0.0032, p = 0.0262) and pregnancy history (β = 0.0019, p < 0.0001) were significantly associated with bulge. Neither the perforator vessel laterality nor the number of perforator vessels harvested had any association with hernia or bulge. Prophylactic mesh placement was not associated with hernia or bulge. Understanding the comorbidities associated with hernia or bulge following DIEP flap breast reconstruction, such as advanced age, prior abdominal surgery, pregnancy history, and active smoking status, allows surgeons to proactively identify and educate high-risk patients. Future studies may further explore whether prophylactic mesh placement offers patients any benefit.

The role of ureteric indocyanine green fluorescence in colorectal surgery: a retrospective cohort study

BackgroundUreteric injury (UI) is an infrequent but serious complication of colorectal surgery. Prophylactic ureteric stenting is employed to avoid UI, yet its efficacy remains debated. Intraoperative indocyanine green fluorescence imaging (ICG-FI) has been used to facilitate ureter detection. This study aimed to investigate the role of ICG-FI in identification of ureters during colorectal surgery and its impact on the incidence of UI.MethodsA retrospective cohort study involving 556 consecutive patients who underwent colorectal surgery between 2018 and 2023 assessed the utility of routine prophylactic ureteric stenting with adjunctive ICG-FI. Patients with ICG-FI were compared to those without ICG-FI. Demographic data, operative details, and postoperative morbidity were analyzed. Statistical analysis included univariable regression.ResultsUreteric ICG-FI was used in 312 (56.1%) patients, whereas 43.9% were controls. Both groups were comparable in terms of demographics except for a higher prevalence of prior abdominal surgeries in the ICG-FI group. Although intraoperative visualization was significantly higher in the ICG-FI group (95.3% vs 89.1%; p = 0.011), the incidence of UI was similar between groups (0.3% vs 0.8%; p = 0.585). Postoperative complications were similar between the two groups. Median stent insertion time was longer in the ICG-FI group (32 vs 25 min; p = 0.001).ConclusionUreteric ICG-FI improved intraoperative visualization of the ureters but was not associated with a reduced UI rate. Median stent insertion time increased with use of ureteric ICG-FI, but total operative time did not. Despite its limitations, this study is the largest of its kind suggesting that ureteric ICG-FI may be a valuable adjunct to facilitate ureteric visualization during colorectal surgery.

Minimally invasive tools are necessary for the modern practice of liver surgery.

Minimally invasive liver resection (MILR) is performed for other gastrointestinal applications. At our centre, all liver resections are systematically performed using a minimally invasive approach. This study aimed to describe our experience in minimising open surgery and emphasised the importance of minimally invasive surgery. We retrospectively reviewed 260 patients who underwent liver surgery and compared the surgical outcomes between the open and MILR groups. A total of 154 patients (68%) underwent MILR. The proportion of patients who underwent prior abdominal surgery and resection was higher in the open surgery group. However, the proportion of patients with liver cirrhosis was similar between the two groups. The MILR group was superior in terms of operative time, blood loss, Pringle manoeuvre rate and mean hospital stay. In addition, major complication and bile leak rates were lower in the MILR group. No significant differences in the tumour size, number of lesions or underlying liver pathology were observed between the two groups. Acceptable outcomes can be achieved even when the minimally invasive approach is considered the primary option for all patients who require liver resection. Minimally invasive tools are necessary for the modern practice of liver surgery; therefore, laparoscopic or robotic surgery should be included in the armamentarium of liver surgeons.

A Rare Case of Bilateral Retroperitoneal Ovaries: A Case Report and Review of the Literature

Introduction: Retroperitoneal gynecologic tumors and cysts are rare. They are often asymptomatic or present similarly to their intraperitoneal counterpart with vague abdominal discomfort and distention. Our literature review revealed that many retroperitoneal cysts are found intraoperatively due to their benign predominance consistent with their ultrasound findings. The rarity of retroperitoneal gynecologic tumors and cysts creates uncertainty regarding the best practice management for general gynecologists caught off guard by their location when found intraoperatively. Rarer still are retroperitoneal ovaries. There are few cases of retroperitoneal ovary displacement in the literature, most often associated with female neonatal incarcerated inguinal hernia repair surgery. We found one case report involving an intraoperatively found retroperitoneal ovarian cystadenofibroma in a patient with a hernia repair performed in infancy. To our knowledge, there are no bilateral retroperitoneal ovaries described in the literature. Objective: To report a rare case of bilateral retroperitoneal ovaries in an 11 year old female. Methods: Case report. Results: We present an 11-year-old female with a past medical history of Dandy-Walker malformation and hydrocephalus status post ventriculoperitoneal (VP) shunt with six laparoscopic VP shunt revisions who endorsed hirsutism and irregular, heavy, and painful menstrual periods. Her family history is significant for polycystic ovarian syndrome (PCOS), endometriosis, and Lynch syndrome. Physical exam revealed mild abdominal distention and lower abdominal tenderness. She had an elevated estradiol, luteinizing hormone (LH), and total and free testosterone. Normally, an elevated estradiol causes a negative feedback response that results in a low LH. Due to these abnormal results, a pelvic ultrasound was ordered to rule out a potential estrogen secreting ovarian tumor. Ultrasound revealed a large anechoic structure in the left adnexa not definitively separated from the ovary measuring 13.0 x 7.7 x 10.7 cm. Radiologic differential diagnosis included large simple cyst, hemorrhagic cyst, and serous neoplasm. A referral to an adolescent gynecologist was made where the patient presented five months later with 25-pound weight gain, constipation, and a hard belly. Repeat ultrasound was consistent with a left ovarian simple cyst with an increased size measuring 16.78 x 12.58 x 8.66 cm as well as a new finding consistent with a right ovarian simple cyst measuring 4.96 x 4.48 x 3.61 cm. Due to her history of severe abdominal adhesions secondary to multiple laparoscopic VP shunt revisions, likely endometriosis, and large ovarian cyst, she was referred to a gynecologic oncologist where she was consented for robotic assisted bilateral ovarian cystectomy and lysis of adhesions. In the operating room, extensive pelvic adhesions were lysed to reveal bilateral retroperitoneal ovaries. The right cyst was drained of clear fluid, revealing no internal complexity, and was completely excised. Persistent pelvic adhesions and cyst size prolonged the time required to excise the left ovarian cyst wall. Once open, papillary excrescences were seen inside the cyst raising concern for a borderline ovarian tumor. The decision was made to remove the cyst wall in its entirety regardless of increased risk of ovarian function compromise. Restoration of normal anatomy was not attainable, and her bilateral ovaries remained embedded in the side walls and superior to the iliac vessels. Pathology revealed a benign 8 cm right paratubal cyst and a benign 18 cm left serous cystadenoma with papillary excrescences. Conclusions: Pelvic anatomy can be greatly distorted secondary to prior abdominal surgeries or certain pathologies including endometriosis and congenital abnormalities. Ultrasound cannot easily discriminate between intraperitoneal and retroperitoneal ovarian cysts but is often the only preoperative imaging obtained prior to cystectomy. Thus, many retroperitoneal cysts are found intraoperatively resulting in diagnostic and therapeutic challenges. Therefore, general gynecologists must be aware of risk factors associated with abnormal pelvic anatomy and prepared to request intraoperative consultation if needed to ensure optimized patient care and safety.

Risk of Bowel Obstruction After Hysterectomy for Benign Indication According to Surgical Method in Denmark, 1984–2013

Study ObjectiveTo estimate the risk of bowel obstruction after hysterectomy for benign indications depending on the surgical method (abdominal, vaginal, or laparoscopic) and identify risk factors for adhesive bowel obstruction. DesignA national registry-based cohort. SettingDanish hospitals during the period 1984-2013. PatientsDanish women who underwent hysterectomy for benign indications (N=125,568). InterventionsAbdominal hysterectomies were compared with vaginal hysterectomies, laparoscopic hysterectomies, and minimally invasive (vaginal and laparoscopic) hysterectomies. Measurements and Main ResultsThe incidence of bowel obstruction according to the surgical method was compared using Cox proportional hazard regression. The covariates included were the time period, age, concomitant operations, prior abdominal surgery or disease, and socioeconomic factors. In a sub-analysis (n=35,712 women) of the period 2004-2013, detailed information from the Danish Hysterectomy Database enabled the inclusion of patient-related, surgery-related, and complication-related covariates.The overall crude incidence of bowel obstruction was 17.4/1000 hysterectomies (2196 incident cases). The 10-year cumulative incidence of bowel obstruction differed between the surgical routes (abdominal, 1.7%; laparoscopic, 1.4%; and vaginal, 0.9%). In multiple adjusted analyses, the risk of bowel obstruction was higher after abdominal hysterectomy than after vaginal (HR 1.64 [95% CI 1.39-1.93]) and minimally invasive (vaginal or laparoscopic) hysterectomy (HR 1.54 [1.33-1.79]). Additional pre-existing risk factors for bowel obstruction at the time of hysterectomy were increased age, low education, low income, smoking, high ASA comorbidity score, history of infertility, abdominal infection, and prior abdominal surgery (apart from cesarean section),penetrating lesions in abdominal organs, or operative adhesiolysis. Perioperative risk factors at the time of hysterectomy included concomitant removal of the ovaries, adhesiolysis, blood transfusion, readmission, and overall presence of perioperative complications. ConclusionAbdominal hysterectomy is associated with a 54% higher risk of bowel obstruction than minimally invasive (laparoscopic or vaginal) hysterectomy.

A descriptive analysis of skin-only closure and Bogota bag techniques for achieving complete fascial closure in damage control abdominal surgery

BackgroundTemporary abdominal closure (TAC) techniques are essential in managing open abdomen cases, particularly in damage control surgery. Skin-only closure (SC) and Bogota bag closure (BBC) are commonly used methods for TAC, but their comparative effectiveness in achieving primary fascial closure (PFC) remains unclear. The objective of this study was to evaluate the rates of PFC between patients undergoing SC and BBC techniques for TAC in peritonitis or abdominal trauma cases at a tertiary care hospital.MethodsA retrospective cross-sectional study was conducted at the Surgical A Unit of Hayatabad Medical Complex, Peshawar, from January 2022 to July 2023. Approval was obtained from the institutional review board, and patient consent was secured for data use. Patients undergoing temporary abdominal closure using either skin-only or Bogota bag techniques were included. Exclusions comprised patients younger than 15 or older than 75 years, those with multiple abdominal wall incisions, and those with prior abdominal surgeries. Data analysis utilized SPSS version 25. The study aimed to assess outcomes following damage control surgery, focusing on primary fascial closure rates and associated factors. Closure techniques (skin-only and Bogota bag) were chosen based on institutional protocols and clinical context. Indications for damage control surgery (DCS) included traumatic and non-traumatic emergencies. Intra-abdominal pressure (IAP) was measured using standardized methods. Patients were divided into SC and BBC groups for comparison. Criteria for reoperation and primary fascial closure were established, with timing and technique determined based on clinical assessment and multidisciplinary team collaboration. The decision to leave patients open during the index operation followed damage control surgery principles.ResultsA total of 193 patients were included in this study, with 59.0% undergoing skin-only closure (SC) and 41.0% receiving Bogota bag closure (BBC). Patients exhibited similar demographic characteristics across cohorts, with a majority being male (73.1%) and experiencing acute abdomen of non-traumatic origin (58.0%). Among the reasons for leaving the abdomen open, severe intra-abdominal sepsis affected 51.3% of patients, while 42.0% experienced hemodynamic instability. Patients who received SC had significantly higher rates of primary fascial closure (PFC) compared to BBC (85.1% vs. 65.8%, p = 0.04), with lower rates of fascial dehiscence (1.7% vs. 7.6%, p = 0.052) and wound infections (p = 0.010). Multivariate regression analysis showed SC was associated with a higher likelihood of achieving PFC compared to BBC (adjusted OR = 1.7, 95% CI: 1.3–3.8, p < 0.05).ConclusionIn patients with peritonitis or abdominal trauma, SC demonstrated higher rates of PFC compared to BBC for TAC in our study population. However, further studies are warranted to validate these results and explore the long-term outcomes associated with different TAC techniques.

Risk factors and outcomes of ectopic pregnancies at lautech teaching hospital, ogbomoso, nigeria: five years review

An ectopic pregnancy is a frequently occurring gynecological illness that poses a significant risk to the mother's health and can be life-threatening. It is the most prevalent emergency during early pregnancy and is connected with a high incidence of maternal morbidity and mortality globally. The objective of this study is to analyze the risk factors and outcomes of ectopic pregnancies at Ladoke Akintola University of Technology (LAUTECH) Teaching Hospital, located in Ogbomoso, Southwestern Nigeria, over a period of five years. This study is a retrospective analysis of women who were admitted and treated for ectopic pregnancy at LAUTECH Teaching Hospital, Ogbomoso, between January 1, 2016, and December 31, 2020. Sociology-demographic variables, risk factors, clinical features, postoperative outcomes, and duration of hospital stay were obtained from medical records using a structured proforma. Data were analyzed with IBM SPSS version 24 to compute frequencies, percentages, means and inferential statistics for hypothesis testing. The occurrence of ectopic pregnancy accounted for 5.23% of all admissions related to gynecological issues, with an incidence rate of 1.68%. The patients’ mean age was 29.84. The most often reported symptom was amenorrhea, with a prevalence of 100%. This was followed in sequence by abdominal pain (96.4%), dizziness (80.9%), fainting attack (60.9%), and shoulder tip discomfort (60%). The most prevalent risk factors observed were pelvic inflammatory disease (61.8%), prior abdominal surgery (43.6%), patient's number of previous pregnancies (41.8%), and history of induced abortion (38.2%). There were no deaths registered. The most often encountered complication was hypovolemic shock. Ectopic pregnancy is still a serious reproductive health issue for women in this region, serving as one of the primary causes of maternal morbidity throughout the early stages of pregnancy. To effectively address the increasing problem of pelvic inflammatory disease and unwanted pregnancy in this specific area, it is crucial to intensify efforts in promoting reproductive health advocacy initiatives.

Prior abdominal surgery is not associated with 30-day mortality or morbidities after endovascular repair of complex abdominal aortic aneurysm.

Prior abdominal surgery (PAS) has the potential to affect outcomes of abdominal aortic aneurysm (AAA) repair. Recently, endovascular aneurysm repair (EVAR) has been expanded among patients with complex AAA, which involves visceral branches in the upper abdominal aortic. However, outcomes of EVAR for complex AAA in patients with PAS have not been examined. This study aimed to investigate the impact of PAS on 30-day outcomes in EVAR for complex AAA. Patients who underwent EVAR for complex AAA were identified in ACS-NSQIP targeted database from 2012 to 2022. Complex AAA was defined as juxtarenal, suprarenal, or pararenal proximal extent, Type IV thoracoabdominal aneurysm, or aneurysms treated with Zenith Fenestrated endograft. Patients with age less than 18 years, ruptured AAA with or without hypotension, acute intraoperative conversion to open, and emergency presentation were excluded. Multivariable logistic regression was used to compare 30-day postoperative outcomes of patients with and without PAS. Demographics, baseline characteristics, aneurysm diameter, indication for surgery, proximal and distant aneurysm extent, anesthesia, and concomitant procedures were adjusted. There were 515 (28.34%) and 1302 (71.66%) patients with and without PAS, respectively, who underwent EVAR for complex AAA. Patients with and without PAS had comparable 30-day mortality (3.11% vs 3.00%, aOR = 0.766, 95 CI = 0.407-1.442, p = .41). Organ system complications including cardiac complications, stroke, pulmonary complications, and renal complications were comparable between patients with and without PAS. All other 30-day outcomes were similar between groups. However, patients with PAS had higher 30-day readmission rate (11.65% vs 7.14%, aOR = 1.634, 95 CI = 1.145-2.331, p = .01). While PAS has high prevalence among patients undergoing EVAR for complex AAA, it does not impact 30-day mortality and morbidities. Thus, EVAR for complex AAA can be considered safe for patients with PAS in terms of short-term outcomes, despite the long-term prognosis in these patients being needed in further studies.

Ureteroenteric strictures after cystectomy: Side-specific risk factors and radiological assessment.

To evaluate risk factors contributing to side-specific benign ureteroenteric strictures following radical cystectomy with an ileal conduit. Data obtained from patients with bladder cancer who underwent radical cystectomy with ileal conduit surgery between 2015 and 2018 were retrospectively analysed. Imaging prior to surgery was analysed, regarding calcifications in the aorta, sarcopenia and postoperatively for length of remaining left ureter. Descriptive analyses were performed on preoperative and perioperative data, comparing patients who developed unilateral left- or right-sided strictures, bilateral strictures, to those who remained free of strictures. COX regression analysis was employed to calculate crude and adjusted hazard ratio for side-specific strictures. The study included 395 patients. Strictures developed in 19% (75/395) of the patients, within a median period of 9months: 57% (43/75) unilateral left sided, 20% (15/75) unilateral right sided and 23% (17/75) bilateral. Unilateral left-sided stricture was associated with higher body mass index (p = 0.077) and hypercholesterolemia (p = 0.007). Right-sided stricture was associated with a history of prior abdominal surgery (p = 0.029) and postoperative leakage (p = 0.004). Bilateral stricture was associated with smoking (p = 0.006) and high BMI (p = 0.015). The adjusted HR comparing patients with and without previous abdominal surgery was only significantly higher for right-sided ureteroenteric strictures (HR 3.18 [95% CI: 1.11; 9.05]) compared with patients without strictures. No association was identified between strictures and preoperative aortic calcification of the abdominal aorta or sarcopenia as estimated from imaging. The aetiology of ureteroenteric strictures appears multifactorial. Our findings suggest that development of left-sided stricture is influenced by factors associated with metabolic syndrome, indicating a potential role of distal ureteric ischemia. On the other hand, right-sided stricture was more frequent in patients with previous abdominal surgery and postoperative leakage.

Soft Tissue Reconstruction After Sacral Neoplasm Resection: The University of California San Francisco Experience.

Resection of sacral neoplasms such as chordoma and chondrosarcoma with subsequent reconstruction of large soft tissue defects is a complex multidisciplinary process. Radiotherapy and prior abdominal surgery play a role in reconstructive planning; however, there is no consensus on how to maximize outcomes. In this study, we present our institution's experience with the reconstructive surgical management of this unique patient population. We conducted a retrospective review of patients who underwent reconstruction after resection of primary or recurrent pelvic chordoma or chondrosarcoma between 2002 and 2019. Surgical details, hospital stay, and postoperative outcomes were assessed. Patients were divided into 3 groups for comparison based on reconstruction technique: gluteal-based flaps, vertical rectus abdominus myocutaneous (VRAM) flaps, and locoregional fasciocutaneous flaps. Twenty-eight patients (17 males, 11 females), with mean age of 62 years (range, 34-86 years), were reviewed. Twenty-two patients (78.6%) received gluteal-based flaps, 3 patients (10.7%) received VRAM flaps, and 3 patients (10.7%) were reconstructed with locoregional fasciocutaneous flaps. Patients in the VRAM group were significantly more likely to have undergone total sacrectomy (P < 0.01) in a 2-stage operation (P < 0.01) compared with patients in the other 2 groups. Patients in the VRAM group also had a significantly greater average number of reoperations (2 ± 3.5, P = 0.04) and length of stay (29.7 ± 20.4 days, P = 0.01) compared with the 2 other groups. The overall minor and major wound complication rates were 17.9% and 42.9%, respectively, with 17.9% of patients experiencing at least 1 infection or seroma. There was no association between prior abdominal surgery, surgical stages, or radiation therapy and an increased risk of wound complications. Vertical rectus abdominus myocutaneous flaps are a more suitable option for patients with larger defects after total sacrectomy via 2-staged anteroposterior resections, whereas gluteal myocutaneous flaps are effective options for posterior-only resections. For patients with small- to moderate-sized defects, local fasciocutaneous flaps are a less invasive and effective option. Paraspinous flaps may be used in combination with other techniques to provide additional bulk and coverage for especially long postresection wounds. Furthermore, mesh is a useful adjunct for any reconstruction aimed at protecting against intra-abdominal complications.

A decade of experience with 530 minimally invasive robotic hepatectomies from a single tertiary hepatobiliary center: analysis of short-term outcomes and oncologic survival

BACKGROUNDThis research presents the first study in the United States to document more than a decade of experience with 530 patients who underwent robotic hepatectomy from a single high-volume institution. METHODSWith IRB approval, a prospectively collected database of consecutive patients who underwent a robotic hepatectomy from 2012 to January 2024 was reviewed. Data are presented as median (mean ± standard deviation). RESULTSOf the 530 robotic hepatectomies, 231 (44%) were minor, 133 (25%) were technically major, and 166 (31%) were major resections. Patients were 63 (61±14.7) years old with a BMI of 28 (29±7.9). Cirrhosis was present in 80 (19%) of patients, with an ASA score of 3 (3±0.5), and MELD score of 7 (8±3.0). 280 (53%) had prior abdominal operations and 44 (8%) had prior liver resections. Operative time was 233 (260±130.7) minutes and estimated blood loss was 100 (165±205.0)mL. 353 (66%) of patients had hepatectomies for neoplastic disease. 500 (95%) had an R0 resection margin. Tumor size was 4 (5±3.6) cm. The total 90-day postoperative complications were 45 (8%) of which 21 (4%) were classified as major complications (Clavien-Dindo >3). The length of stay was 3 (4±3.7) days, and the 30-day readmission rate was 86 (16%). Overall survival at 1, 3, and 5 years was 82%/65%/59% for colorectal liver metastases, 84%/68%/60% for hepatocellular carcinoma, and 79%/61%/50% for intrahepatic cholangiocarcinoma. CONCLUSIONSAfter a decade of application and optimization at a high-volume institution, the robotic approach has demonstrated its utility as a safe and effective approach to liver resections.
