Conventional Versus Two Ports Plus One Puncture Laparoscopic Cholecystectomy: A Clinical Trial

Background: The gold standard treatment for calculus cholecystitis is laparoscopic cholecystectomy (LC). In the conventional laparoscopic cholecystectomy (CLC), three instruments are most useful in ensuring the critical view of safety. The two ports plus one puncture laparoscopic cholecystectomy (TPPOP LC) assisted needle grasper approach upholds the laparoscopic triangulation principles and allows an accessible critical view of safety. This technique successfully reduces port numbers while maintaining equivalent surgical outcomes. Method: The main objective is to compare clinical outcomes of conventional and two ports plus one puncture laparoscopic cholecystectomy. This is a single-center hospital based interventional double-blinded randomized controlled trial that included 98 patients undergoing laparoscopic cholecystectomy at No. (1) Military Hospital (700 bedded) from 01/12/2019 to 31/07/2021. The patients were randomized into group A (CLC) (n = 49) and group B (TPPOP LC) (n = 49). This trial was registered in the ISRCTN registry with the registration number ISRCTN50339464. Results: Among total of 98 patients, 46.9% were male patients and 53.1% were female patients. Mean age in group A was 49.86 ± 7.77 years and in group B was 49.33 ± 7.69 years. Mean operation time in group A was 57.9 ± 6.7 minutes and in group B was 58.5 ± 7.1 minutes, with no significant difference (p = 0.66). Although 4.1% of patients in CLC group and 12.2% in TPPOP LC group experienced bile spillage, no other major intraoperative complications were noted. A significant difference was observed at 36 and 48 hours postoperatively (VAS: 2.69 ± 1.16 in group A and 1.94 ± 0.83 in group B at 36 hours; p = 0.005 and VAS: 1.69 ± 0.92 in group A and 1.33 ± 0.63 in group B at 48 hours; p = 0.002). Postoperative minor wound infection was detected 6.1% in group A and 4.1% in group B (p = 0.64). The mean duration of the postoperative hospital stay was 5.24 ± 1.01 days in group A and 4.98 ± 0.92 days in group B (p = 0.17). Conclusion: This clinical trial concludes that two ports plus one puncture laparoscopic cholecystectomy is as effective and safe as conventional four-port laparoscopic cholecystectomy.

Cephalic to jugular vein bypass surgery of subclavian vein stenosis for arteriovenous fistula salvage in maintenance hemodialysis patients.

Ipsilateral subclavian vein stenosis in a well-functioning upper extremity arteriovenous fistula (AVF) is a significant factor contributing to AVF failure and sometimes swelling of ipsilateral upper extremity. Graft bypass surgery can alleviate outflow tract stenosis in upper extremity AVF, restore function, and efficiently relieve arm swelling. The present study aimed to evaluate patency and postoperative complications after cephalic to jugular graft bypass surgery in patients with upper extremity AVF failure or upper extremity swelling on the same side of the AVF resulting from ipsilateral subclavian vein stenosis. Five patients with upper extremity AVF and ipsilateral subclavian vein stenosis undergoing maintenance hemodialysis were included. Three patients had AVF dysfunction, while two experienced swelling of the arm due to high venous pressure in the AVF. The surgical procedure involved creating a subcutaneous tunnel in the shoulder to connect a 6 mm polytetrafluorethylene (PTFE) graft, from either near the fistula site (n = 3) or at the mid-upper arm cephalic vein (n = 2), to the jugular vein. Graft bypass surgery was successful, and all patients were able to resume hemodialysis postoperatively. Upper extremity edema improved, without any postoperative wound infections, non-healing wounds, steal syndrome, or high-flow AVF leading to heart failure as a complication. Five to 19 months after surgery, the bypass grafts exhibited a primary patency rate of 100%, and vascular access fulfilled the requirements for hemodialysis. Cephalic to jugular vein bypass surgery for upper extremity AVF with ipsilateral subclavian vein stenosis effectively preserved function of the original fistula, and was associated with few postoperative complications.

Hardware Complication Risks in Head and Neck Cancer Patients Undergoing Reconstructive Surgery With Segmental Mandibulectomy

ABSTRACTBackgroundThe primary objective of this study was to ascertain the risk factors associated with hardware complications following segmental mandibular reconstruction in head and neck cancer patients. Additionally, we sought to develop a nomogram model that enables accurate risk prediction.MethodsPatients who underwent segmental mandibulectomy with immediate free or local regional tissue transfer between January 2016 and December 2020 were reviewed. Hardware complications were defined. Patient demographics and perioperative parameters were analyzed.ResultsA total of 510 patients were analyzed. Postoperative radiation therapy (OR = 2.296, 95% CI = 1.339–3.938, p = 0.003), postoperative wound infection (OR = 2.367, 95% CI = 1.472–3.806, p < 0.001), and debridement for flap‐related complications (OR = 5.484, 95% CI = 3.269–9.199, p < 0.001) were identified as independent risk factors. The nomogram model demonstrated good discriminatory ability.ConclusionThis comprehensive analysis identified three independent risk factors, and the nomogram provides a valuable tool for predicting the risks. Further research is needed to validate these findings and explore preventive strategies.

Clinical study of percutaneous endoscopic thoracic spine surgery via trench technique for thoracic spinal cord ventral decompression

To evaluate the feasibility, safety, and early effectiveness of percutaneous endoscopic thoracic spine surgery via the trench technique for ventral decompression in central calcified thoracic disc herniation (CCTDH) and thoracic ossification of the posterior longitudinal ligament (T-OPLL). Seven patients with single-segment CCTDH or T-OPLL admitted between June 2017 and May 2020 and meeting the selection criteria were retrospectively analyzed. There were 3 males and 4 females with an average age of 51.7 years ranging from 41 to 62 years. There were 2 patients with T-OPLL (T 1, 2 in 2 cases) and 5 patients with CCTDH (T 1, 2 in 1 case, T 7, 8 in 1 case, T 10, 11 in 2 cases, T 11, 12 in 1 case). Five patients with thoracic axial pain and intercostal neuralgia had a preoperative visual analogue scale (VAS) score of 6.0 (5.0, 6.5), and 7 patients had a preoperative Japanese Orthopaedic Association (JOA) score of 21 (21.0, 22.0). Transforaminal approach was used in 4 cases and transpedicular approach in 3 cases. Ventral decompression of thoracic spinal cord was performed by thoracic endoscopy combined with trench technique. The operation time, intraoperative blood loss, postoperative hospital stay, and postoperative complications were recorded. Thoracic spine CT and MRI were performed preoperatively and postoperatively to evaluate the surgical decompression, VAS score was used to evaluate the pain of thoracic back and lower limbs, and JOA score was used to evaluate the functional recovery. Modified MacNab criteria was used to evaluate the effectiveness. All surgeries were successfully completed. The operation time ranged from 60 to 100 minutes, with an average of 80.4 minutes; the intraoperative blood loss ranged from 40 to 75 mL, with an average of 57.1 mL; the postoperative hospital stay ranged from 4 to 7 days, with an average of 5.4 days. CT and MRI examinations indicated that the decompression was adequate. All 7 patients were followed up 3-22 months, with an average of 13.3 months. One case developed postoperative wound infection, and 1 case developed pneumonia; the remaining patients did not have any complications such as wound infection or cerebrospinal fluid leakage. Five patients with thoracic axial pain and intercostal neuralgia had VAS scores of 2.0 (1.5, 2.5) at 1 day after operation and 2.0 (1.0, 2.0) at last follow-up, both of which were significantly lower than the preoperative scores ( P<0.05). At 1 day after operation, the JOA scores for all 7 patients were 22.0 (21.0, 24.0), which showed no significant difference compared to the preoperative score ( P>0.05); however, at last follow-up, the score improved to 24.0 (24.0, 26.0), which was significant compared to the preoperative scores ( P<0.05). At last follow-up, the effectiveness was assessed using the modified MacNab criteria, the results were excellent in 2 cases, good in 3 cases, fair in 2 cases, and the excellent and good rate was 71.4%. Using the trench technique, percutaneous endoscopic thoracic spine surgery can achieve the ventral decompression in CCTDH and T-OPLL, providing a new approach for surgical treatment of CCTDH and T-OPLL.

The Impact of Smoking on Sacrocolpopexy Perioperative Outcomes: An Observational Study.

Tobacco smoke is a modifiable risk factor that surgeons discuss with patients prior to undergoing sacrocolpopexy or mesh revision surgery. The aim of the study was to investigate the effect of smoking on perioperative outcomes after sacrocolpopexy for pelvic organ prolapse and mesh revision repair. This was a retrospective cohort study of data obtained from the National Surgical Quality Improvement Project's database. Women who underwent surgery for pelvic organ prolapse via abdominal sacrocolpopexy (ASCP) or minimally invasive sacrocolpopexy (MISCP) or prolapse mesh revision surgery from 2011 to 2021 were identified and compared based on current tobacco use. Demographic, medical, and surgical history, as well as intraoperative and 30-day perioperative outcomes, were compared. Multivariate analysis was performed. Overall, 21,980 women underwent MISCP (8.60% smokers) and 3,775 underwent ASCP (8.74% smokers). Postoperative wound infections were more common after sacrocolpopexy in patients who smoked. Readmission after MISCP was more common in smokers. The composite perioperative morbidity score was different between smokers and nonsmokers for MISCP (P = 0.001) and ASCP (P = 0.002). Multivariate analyses of MISCP outcomes found an association between smoking and wound infection, readmission, and composite score. Multivariate analyses of ASCP outcomes found an association between smoking and wound infection. Overall 2,160 patients underwent mesh removal by any modality (16.57% smokers), and no difference in perioperative outcomes between smokers and nonsmokers for mesh removal was found. An association was found between tobacco smoking and wound infection as well as other postoperative complications. Tobacco use prior to a mesh excision procedure does not appear to increase perioperative outcomes.

Outcome of Triple Negative Breast Cancer(TNBC) as compared to other breast cancers in Bir Hospital, National Academy of Medical Sciences

Introduction: In Nepal, breast cancer is the second most common cancer accounting for a large number of deaths.The subtype Triple-negative breast cancer (TNBC) is linked to poor prognosis and is characterized by the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 (HER2). This study describes the outcome of women with TNBC as compared to other breast cancers in Bir Hospital in Nepal. Methods: This was a cross-sectional study conducted in Bir Hospital, National Academy of Medical Sciences. The breast cancer data in Department of Surgery and Department of Oncology were collected from July 2021 to June 2024. The study data on demographic details, clinical findings, radiological and pathological investigations, operative procedures, neoadjuvant/adjuvant therapy, surgical and oncological outcomeswere collected. The study approval was taken from Institutional Review Board of National Academy of Medical Sciences. Results: There were 72 breast cancer patientsout of which 10 (13.8 %) were TNBC. Majority of the cases (70%) underwent modified radical mastectomy and 60% of them had received neoadjuvant therapy in TNBC cases. One out of 10 had positive margin post mastectomy. The proportion of TNBC patients with postoperative wound infection, seroma and flap necrosis were 10% each. The mean lymph node positivity was less in TNBC group as compared to other breast cancers.There was one recurrence, one metastasis and no mortality till one year follow up. Conclusion: The surgical outcome was satisfactory and with neo-adjuvant, surgery and adjuvant therapy, there is less tumor recurrence and satisfactory disease free survival and overall survival.

Circadian rhythm and daytime variation do not affect intraoperative bacterial sternal contamination and postoperative wound infections following cardiac surgery

Studies have documented various effects of circadian rhythm and daytime variations on the cardiovascular and immune system as well as wound healing. From June to December 2016, n = 367 cardiac surgery patients were enrolled. Microbiological swabs from the mediastinum and subcutaneous wound were taken before sternal closure. Patients were assigned to groups based on operation start: morning (n = 219) or afternoon (n = 135). Bacterial contamination and wound infections were studied in relation to circadian rhythm and daytime variation. We did not observe any difference in mortality (morning: 3.7%, afternoon: 3.0%, p > 0.99) and major adverse events (morning: 8.2%, afternoon: 5.9%, p = 0.53). In 27.7% of the morning group, at least one positive intraoperative swab was observed, similar to the afternoon group (25.6%, p = 0.71). The incidence of positive presternal swabs was 15.6% in the morning compared to 9.1% in the afternoon (p = 0.18). About 90% of the germs detected were part of the natural skin flora (e.g., Cutibacterium acnes and Staphylococcus epidermidis). The incidence of sternal wound infections was 7.3% (morning) and 3.0% (afternoon) (p = 0.18). We did not find differences in the incidence of intraoperative bacterial sternal contamination, nor postoperative infections, between patients who underwent cardiac surgery in the morning or afternoon.

Comparison of outcome of Simple Excision vs Limberg Flap of pilonidal sinus in terms of post operative pain, operative time, wound infection and hospital stay.

Objective: To compare post operative pain, wound infection, intraoperative time and length of hospital stay in both groups of simple excision and Limberg flap. Study Design: Comparative Prospective study. Setting: CMA Teaching and Research Hospital/Azra Naheed Medical and Dental College, Lahore, Pakistan. Period: 1st September 2021 to 1st September 2023. Methods: After approval from the Institutional review board of Azra Naheed Medical &amp; Dental College/CMA Hospital, the sample was 120 patients was raised using non-convenience probability sampling divided into 2 groups. Group A patients underwent simple excision while Group B patients underwent Limberg flap Inclusion criteria include all the patients with age more than 13 years and diagnosed as case of pilonidal sinus. All the data was entered and processed by using SPSS 26. Comparison of two groups was done by apply independent sample t-test. A p-value of ≤ 0.05 was considered significant. Results: The average age of the patients was 45.88 ± 9.78 years with minimum and maximum ages were 15 &amp; 59 year respectively. Mean post operative pain was 2.6 ± 1.9 in group A while 3.9 ± 2.7 in group B (p value = &lt;0.05). Similarly wound infection, duration of surgery and length of hospital stay were also less in group A patients as compared to group B patients. Conclusion: Simple excision of pilonidal sinus is better from Limberg flap in terms of post operative pain, wound infection, duration of surgery and length of hospital stay.

Resurgence of vaginal route of hysterectomy: Comparison based outcomes of abdominal and vaginal hysterectomy.

Objective: To determine the preferable route of hysterectomy by comparing the intra-operative and post-operative complications of non descent vaginal hysterectomy with abdominal hysterectomy. Study Design: Randomized Control Trial. Setting: Madina Teaching Hospital, Faisalabad, Pakistan. Period: January 2022 to December 2022. Methods: Forty cases of each vaginal and abdominal hysterectomy were enrolled for study. Outcome was measured by recording intra-operative and post-operative complications in both groups. Results: Time of surgery, postoperative pain, postoperative blood transfusion, wound infection, febrile morbidity and duration of hospital stay were significantly less (p value 0.0001) in the non descent vaginal hysterectomy compared to abdominal hysterectomy. Conclusion: Non descent vaginal hysterectomy is a safe and cost effective approach when compared to abdominal rout due to less intra and post operative morbidity particularly in settings where facilities and expertise for laparoscopic surgery are lacking.

047. Comparison of Single-Port and Three-Port Laparoscopic Appendicitis Techniques in Adult Appendicitis

Background: Laparoscopic appendectomy (LA) become the standard for treatment of appendicitis in many countries, offering benefits such as quick recovery, fewer postoperative complications, and good cosmetic outcomes. Minimally invasive surgical techniques like single-port laparoscopic appendectomy (SPLA) are increasingly performed for better cosmetic results. However, the outcomes and safety of this technique compared to conventional three-port laparoscopic appendectomy (CTLA) still debated among experts. To compare the outcomes between SPLA and CTLA in adult appendicitis, focusing on outcomes such as postoperative wound infection rates, operating time, and surgical costs. Methods: Comprehensive search through various online databases such as PubMed, ScienceDirect, Scopus, Cochrane, and Google Scholar from 2014-2024 was performed. This research was conducted following the PRISMA guidelines. Oxford Evidence-Based Medicine criteria to assess the quality of the paper. Articles that fulfilled the eligibility criteria were retrieved and extracted for study characteristics and outcomes. Results: Four studies met the inclusion criteria, 434 patients undergoing either SPLA or CTLA procedures. There were no significant differences in complication rates such as wound infection and ileus between the two techniques. Conclusion: The SPLA technique is safe and reliable option with advantages in better cosmetic outcomes and shorter hospital stay duration, despite requiring longer operating time compared to CTLA.

Surgical Complications after Targeted Muscle Reinnervation at a Safety-Net Hospital.

Targeted muscle reinnervation (TMR) and regenerative peripheral nerve interface (RPNI) can reduce neuroma formation and phantom limb pain (PLP) after lower extremity (LE) amputation. These techniques have not been studied in safety-net hospitals. This study aims to examine the surgical complication rates after TMR and/or RPNI at an academic safety-net hospital in an urban setting. This was a retrospective review of patients older than 18 years who had prior above-knee guillotine amputation (AKA) or below-knee guillotine amputation (BKA) and underwent stump formalization with TMR and/or RPNI from 2020 to 2022. Demographics, medical history, and operative and postoperative characteristics were collected. The primary outcome was any surgical complication, defined as infection, dehiscence, hematoma, neuroma, or reoperation. Univariate analysis was conducted to identify variables associated with surgical complications and PLP. Thirty-two patients met the inclusion criteria. The median age was 52 years, and 75% were males. Indications for amputation included diabetic foot infection (71.9%), necrotizing soft tissue infection (25.0%), and malignancy (3.1%). BKA was the most common indication for formalization (93.8%). Most patients (56.3%) had formalization with TMR and RPNI, 34.4% patients had TMR only, and 9.4% had RPNI alone. The incidence of postoperative complications was 46.9%, with infection being the most common (31.3%). The median follow-up time was 107.5 days. There was no significant difference in demographics, medical history, or operative characteristics between patients who did and did not have surgical complications. However, there was a trend toward higher rates of PLP in patients who had a postoperative wound infection (p = 0.06). Overall complication rates after LE formalization with TMR and/or RPNI at our academic safety-net hospital were consistent with reported literature. Given the benefits, including reduced chronic pain and lower health care costs, we advocate for the wider adoption of these techniques at other safety-net hospitals.

Rifampicin-Loaded PLGA/Alginate-Grafted pNVCL-Based Nanoparticles for Wound Healing

The topical therapy with rifampicin (RF)-based formulations is beneficial for treating postoperative wound infections and to accelerate healing. Despite recent research highlighting the antibiotic’s significant anti-inflammatory properties, limited topical wound healing products are currently available. The present study aimed to prove that the newly synthesized nanoparticles based on grafted alginate and poly(N-vinylcaprolactam) (pNVCL) and poly-lactic-co-glycolic acid (PLGA) contribute to the healing process of a wound. The methods used were at first the synthesis of the copolymer of alginate and pNVCL via grafting from technique and radical polymerization followed by water-in-oil-in water (W/O/W) emulsification; as oil phase PLGA dissolved in dichloromethane (DCM) was used. The formed nanoparticles were than characterized. The loaded RF was determined to be 160 µg/mL for a 20 mg formulation and within a four-hour time frame approximately 10% of the total loaded amount was released. The inhibitory concentrations (IC50) were 192.1 µg/mL for the nanoparticle, 208.8 µg/mL for pure rifampicin, and 718.1 µg/mL for the rifampicin-loaded nanoparticles. Considering the double role rifampicin was used for, the result was considered satisfactory in the way that these formulations could be used predominantly for postoperative wound irrigation in order to avoid infections and to improve healing.

Low Preoperative Albumin Levels Significantly Associated with Increased Risk of Wound Infection and Bleeding After Panniculectomy.

Introduction: Panniculectomy is recognized to have a high complication rate with up to 56% of patients having postoperative wound healing problems. As they are generally elective procedures, surgeons have the chance to optimize preoperative variables. We reviewed the relationship between preoperative serum albumin and BMI with short-term postoperative panniculectomy complications. Methods: Patients undergoing panniculectomy between January 2005 and December 2019 were identified via CPT code 15830 from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Multivariate logistic regression was performed on intra/postoperative bleeding and postoperative wound infection against preoperative serum albumin, diabetes status, age, body mass index (BMI), and smoking status. Odds ratios were adjusted for comorbidities. We established statistical significance at p value <0.01. Results: Out of 1472 patients, 69 sustained intra/postoperative bleeding and 31 suffered wound infection. Lower preoperative albumin levels (R2 = 16.3%, p < 0.0001) and elevated BMI (R2 = 9.4%, p < 0.0001) were both significantly associated with increased likelihood of wound infection. For every 1 g/dL decrease in albumin, patients' odds of bleeding increased 1.85 (OR = 1.85, CI 95%= [1.14-2.99]) times, and odds of wound infection increased 5.03 (OR = 5.03, CI 95%= [2.78-9.10]) times (p < 0.0001). BMI and albumin were weakly correlated (r = -0.28) suggesting each had independent effects on complications. Conclusion: In patients undergoing panniculectomy, preoperative albumin level is significantly inversely associated with postoperative bleeding and wound complications. More research is needed to evaluate whether proactively optimizing albumin may reduce complications.

A Polyurethane Electrospun Membrane Loaded with Bismuth Lipophilic Nanoparticles (BisBAL NPs): Proliferation, Bactericidal, and Antitumor Properties, and Effects on MRSA and Human Breast Cancer Cells.

Electrospun membranes (EMs) have a wide range of applications, including use as local delivery systems. In this study, we manufactured a polyurethane Tecoflex™ EM loaded with bismuth-based lipophilic nanoparticles (Tecoflex™ EMs-BisBAL NPs). The physicochemical and mechanical characteristics, along with the antitumor and bactericidal effects, were evaluated using a breast cancer cell line and methicillin-susceptible and resistant Staphylococcus aureus (MRSA). Drug-free Tecoflex™ EMs and Tecoflex™ EMs-BisBAL NPs had similar fiber diameters of 4.65 ± 1.42 µm and 3.95 ± 1.32 µm, respectively. Drug-free Tecoflex™ EMs did not negatively impact a human fibroblast culture, indicating that the vehicle is biocompatible. Tecoflex™ EMs-BisBAL NPs increased 94% more in size than drug-free Tecoflex™ EMs, indicating that the BisBAL NPs enhanced hydration capacity. Tecoflex™ EMs-BisBAL NPs were highly bactericidal against both methicillin-susceptible S. aureus and MRSA clinical isolates, inhibiting their growth by 93.11% and 61.70%, respectively. Additionally, Tecoflex™ EMs-BisBAL NPs decreased the viability of MCF-7 tumor cells by 86% after 24 h exposure and 70.1% within 15 min. Regarding the mechanism of action of Tecoflex™ EMs-BisBAL NPs, it appears to disrupt the tumor cell membrane. In conclusion, Tecoflex™ EMs-BisBAL NPs constitute an innovative low-cost drug delivery system for human breast cancer and postoperative wound infections.

Early injection laryngoplasty for acute unilateral vocal fold paralysis after thoracic aortic surgery

ObjectiveUnilateral vocal fold paralysis (UVFP) following open thoracic aortic surgery increases pulmonary complications and hospital stays. An intervention protocol with early injection laryngoplasty (IL) and swallowing maneuvers was developed for acute UVFP following thoracic aortic surgery. This study aimed to compare the incidence of complications and length of medical care between the non-VFP and the IL-UVFP group managed under this protocol. MethodsPatients who underwent open thoracic aortic surgery from March 2020 to February 2023 were included, excluding those with preoperative VFP or postoperative bilateral VFP. Under the protocol, patients with UVFP and incomplete glottic closure received IL and swallowing maneuvers within one week after diagnosis, while those without a glottic gap started a soft diet along with swallowing maneuvers. Postoperative complications, including reintubation, ICU re-transfer, pneumonia, stroke, delirium, wound infection, and bleeding, as well as hospital and ICU stay, were assessed. ResultsOf the 355 patients included in the study, 51 (14.4%) developed postoperative UVFP, while 304 (85.6%) had normal VF function. In the UVFP group, 42 patients underwent IL, while 9 patients without a glottic gap did not undergo IL. The incidence of complications and length of medical care were analyzed in the non-VFP and the IL-UVFP groups. The IL-UVFP group had a longer median hospital stay compared to the non-VFP group (20.5 vs. 16.0 days), though this difference was not statistically significant (P = .0681). ICU stay (P = .5396) and ICU re-transfer rates (P = 1.00) were also comparable between the groups. There was no significant difference in the incidence of pneumonia between the IL-UVFP group (4.8%) and the non-VFP group (9.5%) (P = .4003). Additionally, no significant differences were observed in the incidence of stroke, delirium, wound infection, or bleeding between the groups. No IL-related complications were reported. ConclusionsThe protocol with early IL appears to help reduce complication rates in acute UVFP patients following thoracic aortic surgery to levels comparable to those in patients without VFP. This protocol could serve as a guideline for otolaryngologists in managing UVFP patients. Level of evidence2b/Individual cohort study.

A Comparative Study of Choledochoduodenostomy Versus Open Choledochotomy With T Tube Placement in a Hospital Lacking Endoscopic Retrograde Cholangiopancreatography.

Choledocholithiasis, or stones in the common bile duct (CBD), has two types: primary stones that form in the CBDand secondary stones that migrate from the gallbladder. Management includes endoscopic, laparoscopic, and open surgical methods. In India, the availability of endoscopic retrograde cholangiopancreatography (ERCP)and laparoscopic surgery is limited often necessitating open procedures. Commonly, open choledochotomy followed by T tube placement was performed. However, postoperative management/management of retained stones can be challenging, requiring referrals for ERCP or revision surgery. This study aims to compare the outcomes of choledochoduodenostomy versus the T tube approach in a hospital setup where ERCP is either unavailable or cumbersome. This was a retrospective comparative study carried out at Rajendra Institute of Medical Sciences (RIMS), Ranchi, Jharkhand, India. The study was approved by the Institutional Ethics Committee of RIMS, Ranchi. A total of 62 patients who underwent operations for choledocholithiasis (CBD dilation ≥ 1.2 cm) from January 2023 to January 2024 in the Department of General Surgery of RIMS, Ranchi, were analyzed. The mean age group was 52 years ± 11.5 years, and two-thirds were females with a male-to-female ratio of 1:1.8. The most common presentation was biliary colic (87 %), followed by jaundice (45%). Around three-fourths of them had multiple calculi (n = 46). A total of 36 patients underwent T tube (58.1%) and 26 underwent choledochodudoenostomy (41.9 %). The mean operating time washigher for the T tube approach but not statistically significant. The hospital stay for the patients was significantly higher for the T tube approach with a p-value of <0.001. The mean T tube in situ duration was 17.60 days ± 1.2 days. On performing a T tube cholangiogram postoperatively, it was observed around one-fourth of them had T tube filling defect (n = 8), signifying the residual stone presence and referral to higher centerdue to unavailability of ERCP. The incidence of wound infection was significantly high among the patient who underwent T tube with a p-value of 0.017, and postoperative bile leak was significantly high among the patient who underwent T tube with a p-value of 0.047. Based on our retrospective analysis, we suggest choledochoduodenostomy was safer and more efficient in aspects of lesser operating time, minimal hospital stay, less or nil retained stones,lesser postoperative wound infection, bile leakage, and possessing advantages especially to elderly patients both economically and psychologically.

Transperineal minimally invasive surgery during laparoscopic abdominoperineal resection for low rectal cancer could improve short-term outcomes: A single-institution retrospective cohort study.

Transperineal minimally invasive surgery (TpMIS) during laparoscopic abdominoperineal resection (APR) is an emerging approach that allows for the precise treatment of lower rectal cancer. However, evidence regarding the efficacy of TpMIS is insufficient. This study evaluated the efficacy of TpMIS during laparoscopic APR for patients with lower rectal cancer. Patients who underwent laparoscopic APR with TpMIS (TpMIS group; n = 12) and those who underwent conventional laparoscopic APR for low rectal cancer (conventional group; n = 13) were enrolled consecutively in this retrospective study. Standardized TpMIS was performed at our institution. Patient and tumor characteristics and intraoperative, postoperative, and pathological outcomes were compared between groups. The primary outcome was postoperative perineal wound infection. No patients in the TpMIS group experienced postoperative perineal wound infection; however, five (38.5%) patients in the conventional group experienced postoperative perineal wound infection (significant difference; p = 0.016). The estimated blood loss (median, 81mL vs. 463mL) and incidence of postoperative urinary dysfunction (8.3% vs. 46.1%) were significantly lower in the TpMIS group than in the conventional group. The postoperative hospital stay (median, 13 vs. 20days) of the TpMIS group was significantly shorter than that of the conventional group. Pathological outcomes did not differ between groups. The positive circumferential resection margin rates of the TpMIS and conventional groups were 8.3% and 15.4%, respectively. TpMIS during laparoscopic APR was associated with significant improvements in the postoperative outcomes of patients with low rectal cancer.

Do Obese Patients Have Worse Outcomes in Adult Spinal Deformity Surgeries? A Meta-Analysis.

Meta-Analysis. This meta-analysis evaluates the difference in surgical outcomes between obese and non-obese patients undergoing adult spinal deformity (ASD) corrective surgery. ASD encompasses a wide range of debilitating spinal abnormalities. Concurrently, obesity is on the rise globally and has been shown to influence the outcomes of ASD management. The relationship between obesity and surgical outcomes in ASD has been the focus of recent studies, yielding various results. We conducted a comprehensive search of PubMed, Cochrane, and Google Scholar (page 1-20) through June of 2024. The surgical outcomes assessed included post-operative complications, revision rates, wound infections, thromboembolic events, implant-related complications, and non-home discharge. Surgical parameters such as operative time, length of stay (LOS), and estimated blood loss (EBL), as well as functional outcomes like the Oswestry Disability Index (ODI) and pain scores were analyzed. Nine studies met inclusion criteria. Non-obese patients exhibited a lower rate of implant-related complications (OR=0.25; 95% CI: 0.12-0.52, P=0.0002) and non-home discharge (OR=0.52; 95% CI: 0.32-0.84, P=0.007). Additionally, non-obese patients had reduced LOS (MD=-0.29; 95% CI: -0.53 - -0.05, P=0.02) and EBL (SMD=-0.68; 95% CI: -1.19 - -0.18, P=0.008). No statistically significant differences were observed for the remaining outcomes. Non-obese patients undergoing ASD corrective surgery are associated with fewer implant-related complications, a lower EBL, shorter LOS, and a higher likelihood of being discharged home compared to their obese counterparts.
