Traditional Open Approach Research Articles

Comparison of pain between laparoscopic percutaneous extraperitoneal closure (LPEC) and open procedure for inguinal hernias in children below 5years of age.

The laparoscopic approach (LA) for repairing inguinal hernias (IH), especially laparoscopic extraperitoneal percutaneous closure (LPEC) has become popular minimally invasive surgical technique. However, invasiveness is difficult to evaluate in children of < 5years of age, as they cannot adequately express their pain. The current study utilized a pain scoring system compare pain in patients of < 5years of age who were treated by LA or traditional open approach (OA). The records of 74 IH patients of < 5years of age who underwent surgery in our hospital between January 2022 and July 2023 were reviewed.Revised Face, Legs, Activity, Cry, and Consolability (FLACC) scores were used to quantitatively evaluate the degree of pain. Forty-seven patients (mean age, 2.85years) underwent treatment with an OA, and 27 patients (mean age, 2.37years) underwent treatment with an LA. The FLACC scores in the OA and LA groups were 0.21 and 0.44, respectively. In a subanalysis by age groups, The FLACC scores in the OA and LA groups were 0.09 and 0.5 in patients of < 2years of age, respectively, CONCLUSION: The reduced invasiveness of LArelative to OAdid not minimize postoperative pain, especially in patients < 2years of age.

Internal hernia following laparoendoscopic single site surgery: a case report

Laparoscopic donor nephrectomy was introduced in 1995 as a means of minimally invasive surgeries that entail kidney extraction from healthy individuals. Since then, it has widely overtaken the traditional open surgical approaches, especially in live donor nephrectomy procedures worldwide. Laparoendoscopic single-site surgery is considered a more optimized surgical approach utilizing a single incision instead of four. Various studies have scrutinized many of the risk factors related to such surgeries, most commonly: vascular problems, intraoperative organ injury, and postoperative ileus. Other rare complications have not been thoroughly explored due to their decreased prevalence. Internal hernias are considered a rare complication of laparoendoscopic single-site surgery with dangerous repercussions ranging from bowel obstruction to ischemia, and necrosis. Our study presents a rare case of a trans-mesenteric internal hernia following laparoendoscopic single-site surgery. The patient was relatively healthy with no serious medical conditions. However, the past medical history did record a diagnosis of irritable bowel syndrome a few years back. Knowing that the occurrence of internal hernias is infrequent, we recommend that mesenteric defects be taken seriously to avoid the risk of internal hernias and their complications.

Is minimally invasive surgery a game changer in spinal surgery?

Minimally invasive spine surgery (MISS) has revolutionized the treatment of spinal disorders over the past few decades. This review provides an in-depth analysis of MISS techniques, technologies, outcomes, and future directions. The evolution of MISS techniques-including tubular retractor systems, percutaneous pedicle screw fixation, minimally invasive transforaminal lumbar interbody fusion, lateral lumbar interbody fusion, and endoscopic spine surgery-has expanded the scope of treatable spinal pathologies while minimizing tissue trauma. Technological advancements such as intraoperative navigation, robotics, and augmented reality applications have enhanced precision and capabilities. Clinical evidence supports the efficacy and safety of MISS techniques for various spinal pathologies, demonstrating comparable or superior outcomes to traditional open approaches with reduced tissue trauma, blood loss, and hospital stays. Cost-effectiveness analyses also favor MISS over open techniques. Future directions in MISS include expanding indications, integrating artificial intelligence and machine learning, advancing tissue engineering and biologics, and refining robotic and augmented reality applications. As MISS continues to evolve, it is poised to play an increasingly important role in the treatment of spinal disorders, offering improved patient outcomes with reduced morbidity. However, ongoing rigorous evaluation of new techniques and technologies is crucial to balance potential benefits with associated risks and costs.

Open vs. laparoscopic vs. robotic pouch excision: unveiling the best approach for optimal outcomes.

Despite advantages for patients with ulcerative colitis, Crohn's disease, and familial adenomatous polyposis, restorative proctocolectomy with ileal pouch-anal anastomosis carries a risk of pouch failure, necessitating pouch excision. The traditional open approach is associated with potential complications. Robotic and laparoscopic techniques are emerging, but comparative outcome data are limited. We conducted a retrospective study of consecutive adult patients undergoing robotic, laparoscopic, and open ileal pouch excision at Mayo Clinic, Rochester, MN, between January 2015 and December 2023. We analyzed data on patient characteristics, perioperative variables, and postoperative outcomes, focusing on short-term complications. Statistical analysis included appropriate tests. The study included 123 patients: 23 underwent robotic-assisted pouch excision, 12 laparoscopic, and 82 open. The robotic approach had the longest median operative time (334 ± 170min, p = 0.03). However, it demonstrated significantly lower estimated blood loss than open (150 ± 200ml vs. 350 ± 300ml, p = 0.002) and laparoscopic surgery (250 ± 250ml, p = 0.005). Robotic and laparoscopic groups required fewer preoperative ureteral stents than the open group (p = 0.001). Additionally, the robotic approach utilized fewer pelvic drainages (p < 0.0001) and had a lower rate of lysis of adhesions > 60min compared to open surgery (p = 0.003). Robotic procedures had significantly lower 30-day postoperative complications than the open approach (30.4% vs. 65.9%, p = 0.002) while also demonstrating fewer 30-day reoperations than the laparoscopic group (p = 0.04). Robotic-assisted pouch excision offered significant benefits, including decreased EBL, reduced need for preoperative ureteral stents, and significantly fewer 30-day postoperative complications compared to open surgery.

The role of endoscopic endonasal surgery in the management of sinonasal malignant tumors with skull base involvement

Sinonasal malignant tumors (SNMTs) represent a rare and heterogeneous group of tumors. SNMTs often present late which can lead to complex, patient-specific treatment decisions. Over the last two decades, endoscopic endonasal surgery (EES) has become a more frequently utilized surgical approach to removing these tumors. Increasingly, studies have compared the outcomes of this approach to traditional open approaches for different SNMTs. Differences in histology and extent of invasion impact the utility of EES. Negative margins are critical for improving survival; however, skull base involvement can add anatomical challenges for achieving negative margins during EES. This paper reviews the literature on outcomes of EES for SNMTs with skull base involvement and presents evidence supporting the utility of EES for select patients. EES is a safe and effective treatment in patients with less invasive SNMTs or less aggressive histology and can provide patients with fewer complications and morbidity than traditional open approaches. As such, it plays a key role in surgical management, providing either sole access or a critical avenue for SNMT removal. EES plays a key role in the multimodal oncological approach to the treatment of different SNMT histologies.

Embracing Robotics in Microsurgery: Robotic-Assisted Deep Inferior Epigastric Perforator Flap Breast Reconstruction.

The integration of robotic-assisted surgery (RAS) has transformed various surgical disciplines, including more recently plastic surgery. While RAS has gained acceptance in multiple specialties, its integration in plastic surgery has been gradual, challenging traditional open methods. Robotic-assisted deep inferior epigastric perforator (DIEP) flap breast reconstruction is a technique aimed at overcoming drawbacks associated with the traditional open DIEP flap approach. These limitations include a relatively large fascial incision length, potentially increasing rates of postoperative pain, abdominal bulge, hernia rates, and core weakening. The robotic-assisted DIEP flap technique emerges as an innovative and advantageous approach in fascial-sparing abdominal autologous breast reconstruction. While acknowledging certain challenges such as increased operative time, ongoing refinements are expected to further improve the overall surgical experience, optimize results, and solidify the role of robotics in advancing reconstructive microsurgical procedures in plastic surgery. Herein, the authors provide an overview of robotic surgery in the context of plastic surgery and its role in the DIEP flap harvest for breast reconstruction.

Robot-Assisted Extravesical Ureteral Reimplantation (REVUR) in Pediatric Patients: A New Standard of Treatment for Patients with VUR-A Narrative Review.

Robot-assisted extravesical ureteral reimplantation (REVUR) was described for the first time in 2004. Since then, the surgical approach of vesicoureteral reflux (VUR) has changed dramatically. The benefits of this technique are great when compared to the laparoscopic or traditional open approaches. A literature search of PubMed was performed to identify articles covering any aspect of REVUR in the pediatric population. A total of 108 papers published over the period 2004-2024 were collected. Of these, 40 studies were considered valuable in terms of obtaining a complete overview of the REVUR technique. This review aimed to describe the current state of the art of REVUR and define it as the new standard technique for surgical management of selected patients with VUR.

403. ROBOTIC-ASSISTED IVOR LEWIS ESOPHAGECTOMY COMPARED TO CONVENTIONAL MINIMALLY INVASIVE ESOPHAGECTOMY: RESULTS FROM SEVEN HIGH VOLUME ITALIAN CENTERS

Abstract Background Over the past decade, minimally invasive esophagectomy has gained increasing attention, supported by numerous trials and retrospective series highlighting its advantages over the traditional open approach. In addition to the conventional minimally invasive surgery (CMIE), robotic assisted minimally invasive esophagectomy (RAMIE) has gained global popularity, due to its advantages in terms of 3D visualization and instrument stability. Methods This is a collaborative study involving seven high-volume Italian centers affiliated with the Italian Society for the Study of Esophageal Diseases (SISME). Patients who underwent Ivor Lewis esophagectomy for esophageal cancer between January 2015 and July 2022 were identified from seven institutional databases and divided in two groups according to the thoracic approach: CMIE versus RAMIE. Results We identified 316 patients in CMIE and 123 in RAMIE group. Operative time was significantly longer for RAMIE procedures (p&amp;lt;0.001). A borderline significant reduction in overall complication rate was observed (48% vs 59% in CMIE group, p=0.045), however there were no differences in severe (p=0.3) and pulmonary (p=0.13) complications rate. 90-day mortality (CMIE 3.2% vs RAMIE 0.8%, p=0.15) and readmission rate (CMIE 9.5% vs RAMIE 7.3%, p=0.47) were comparable. R0 rate was 94.9% in CMIE vs 92.7% in RAMIE (p=0.4). The most performed anastomosis was circular stapled anastomosis. Anastomotic leak rate was 13.9% for CMIE and 12.2% for RAMIE (p=0.6). Conclusion Minimally invasive Ivor Lewis esophagectomy has reached adequate surgical and oncological results with both conventional and robotic technique. Nowadays there is no clear superiority of one anastomotic technique.

475. MINIMALLY INVASIVE IVOR -LEWIS ESOPHAGECTOMY - ANALYSIS OF PERIOPERATIVE ONCOLOGICAL AND SHORT TERM OUTCOMES

Abstract Background Trans thoracic Ivor-Lewis esophagectomy is the widely adopted procedure for gastroesophageal junction adenocarcinoma. Minimally invasive esophagectomy has been shown to be superior in comparison to the traditional open approach in terms of pulmonary complications and lymph node yield. We present our experience of minimally invasive Ivor-Lewis esophagectomy in this review. Methods A retrospective review of the patients who underwent minimally invasive Ivor-Lewis esophagectomy at a single center between September 2009 and April 2023 was performed. The perioperative and short term outcomes were analyzed. Results A total of 195 patients [147 males (75.38%)] underwent minimally invasive Ivor-Lewis esophagectomy during the study period. The median (range) age was 62 (48-77) years. The median operative time was 435 (310-530) minutes. The median estimated blood loss was 125 (80-250) ml. R0 resection was achieved in all the patients. The median lymph node yield, ICU stay and overall hospital stay were 22 (12-30), 3.5 (2-12) days and 10 (7-33) days respectively. Pulmonary complications were the most common seen in 24 (12.31%) patients. Anastomotic leak was noted in 5 (2.56%), chyle leak in 2 (1.02%), recurrent laryngeal nerve paresis in 12 (6.15%) patients. Anastomotic stricture was noted in 22 (11.28%) patients who were managed with endoscopic dilatation. Thirty day mortality was observed in 4 (2.05%) patients. Conclusion Minimally invasive Ivor-Lewis esophagectomy is associated with good perioperative oncological and short term outcomes when performed in a specialist esophageal center

UBE as a modern approach to the surgical treatment of intervertebral disc herniations with lumbar spinal stenosis

Aim. To improve the results of surgical treatment of lumbar disc herniation using biportal endoscopy.Material and Methods. We analysed the diagnostic data and surgical results of 23 patients diagnosed with disc herniation and stenosis in the lumbar spine. The study period covers the years 2021 to 2023. During the study, all 23 patients underwent a series of diagnostic procedures: clinical neurological examination, CT, MRI and functional radiography. The patients were divided into 2 groups according to the method of surgical intervention: the main group (n=23), where unilateral biportal endoscopy was used, and the control group (n=20), where endoscopic discectomy was used.Results. Long-term outcomes were assessed using the MacNab scale at 9 months after surgery. 82.6% of patients had excellent outcomes. In 2 (8.8%) cases, the results were good; these patients had moderate pain that had completely disappeared by the time they were discharged from hospital. One patient (4.3%) had a satisfactory result, but continued to have moderate nagging pain, which disappeared in the first seven days after discharge from the medical facility. Poor outcome was reported in 1 case (4.3%); this patient had persistent radicular pain due to the development of postoperative neuritis. There were no cases of recurrent disc herniation.Conclusion. The unilateral biportal endoscopic discectomy (UBE) is a minimally invasive and promising technique that can be used as an alternative to the traditional open surgical approach.

Full SMAS: Endoscopy-Assisted Full Facial Rejuvenation.

Every region of the face may bear the signs of aging. Treating isolated areas without adequate anatomical knowledge can lead to incomplete or artificial-looking results and decrease patient satisfaction. The authors' "Full SMAS" technique for complete rejuvenation addresses the anatomical continuity of the superficial musculoaponeurotic system (SMAS)-platysma to the deep-plane suspension of the face. The aim of this study was to evaluate the contribution of endoscopic techniques to traditional facelift and neck lift procedures. Procedures treating from the frontal and temporal regions of the superior part of the face to its mid and lower parts, including the cervical region, were evaluated. Treatment of the 3 sub-SMAS layers of the face was performed using endoscopy for repositioning the frontal region and midface. This procedure involved frontal and zygomatic-masseter ligament release, open treatment of the lower subplatysmal section, and the complete release of the retaining ligaments of the face and approach to the jowl. One hundred sixty-one patients underwent the Full SMAS technique, leading to long-lasting results, low complication rates, and high patient satisfaction. The Full SMAS is a systematic technique that provides complete facial rejuvenation by combining an endoscopic approach for the temporal and midface regions with traditional open approaches for the lower face and neck. Treating the temporal and midface regions by minimally invasive techniques (endoscopy) reduces the possibility of permanent nerve injuries, provides smaller scars, and creates natural, long-lasting results.

Minimally Invasive Surgery for Duodenal Obstructions, 10 Years of Experience in a Single Center

PurposeDuodenal obstructions are one of the most common causes of upper intestinal obstruction during the neonatal period. Minimally invasive surgical treatment is considered highly complex. We report our experience with 43 patients treated using this method. MethodsWe conducted a retrospective study at our institution from January 2013 to May 2023, including patients classified as having upper intestinal obstructions. All patients received preoperative diagnoses based on clinical findings, radiography, and abdominal ultrasound. Laparoscopic surgery was performed on all patients. ResultsWe included 43 patients diagnosed with duodenal obstruction (DO) in our study after reviewing the medical records at our hospital for cases meeting this diagnosis. The laparoscopic Kimura procedure was performed on 31 patients (72%), while duodenotomy and anastomosis following the Heineke-Mikulicz principle were performed on 9 patients (21%). In the remaining 3 patients (7%), a side-to-side duodeno–duodeno anastomosis was conducted. Annular pancreas was the most common cause of duodenal obstruction in our series, affecting 21 patients (49%). Type I duodenal atresia was observed in 17 patients (40%), while type III atresia was present in 3 patients (7%), and type II atresia in 2 patients (4%). One case required conversion to open surgery due to concomitant jejunoileal atresia. The only reported complication was partial anastomotic dehiscence, which occurred in two patients (4%). ConclusionsMinimally invasive surgery (MIS) for managing duodenal obstruction (DO) has proven to be both feasible and safe, yielding comparable outcomes to the traditional open approach; its effectiveness can be significantly enhanced through appropriate training. Furthermore, the growing availability of duodenal atresia simulators offers valuable opportunities to refine laparoscopic skills and apply them effectively. Better outcomes and fewer complications are expected with further experience and an increased number of cases. Level of EvidenceIV, Case series with no comparison group.

Full-Endoscopic Spinal Surgery for Older Patients With Degenerative Spinal Pathology: A Narrative Review

The aging population worldwide is experiencing an increasing incidence of degenerative spinal disorders, leading to significant morbidity and diminished quality of life. Traditional open surgical approaches for treating these conditions in older patients often entail substantial risks and prolonged recovery times. However, recent advancements in endoscopic surgical techniques have provided promising alternatives with potentially reduced morbidity and quicker recovery. This paper reviews the current literature regarding full-endoscopic spinal surgery (FESS) for degenerative spinal pathology in older patients. We discuss the evolution of endoscopic techniques, patient selection criteria, surgical indications, outcomes, and complications associated with FESS in older adults. Several studies have reported favorable outcomes of FESS in older patients, including reduced postoperative pain, shorter hospital stays, faster recovery, and comparable or even improved clinical outcomes compared with traditional open surgery. Moreover, FESS offers the advantages of minimal tissue disruption, preservation of spinal stability, and decreased blood loss, which are particularly advantageous in older patients with multiple comorbidities. However, challenges such as a steep learning curve for surgeons, limited visualization, and technical constraints in managing complex pathologies remain significant concerns. Additionally, the long-term durability and effectiveness of FESS in older patients require further investigation. In conclusion, FESS presents a promising minimally invasive option for treating degenerative spinal pathology in older adults. Further research and technological advancements are needed to optimize patient selection, refine surgical techniques, and improve long-term outcomes in this growing demographic category of patients.

Robotic versus open mini-incision living donor nephrectomy: Single centre experience.

Robotic surgery is associated with less tissue manipulation and earlier recovery with minimal incision. The aim of this study was to compare the short-term clinical outcomes between robotic-assisted donor nephrectomy (RDN) and open mini-incision donor nephrectomy (ODN). From 2016 to 2019, 141 cases involving RDN were analysed. Patient outcomes were compared with those of 191 patients who underwent ODN from 2010 to 2015. Demographics, operation factors, perioperative outcomes, and complications were retrospectively reviewed. The RDN group presented with less blood loss than the ODN group (p=0.023). The length of hospital stay was significantly shorter in the RDN group than in the ODN group (p<0.005). The overall rate of complications was low and there was no significant difference in complication rates between the groups. The robotic approach has benefits over the traditional open approach, including shorter length of hospital stay and reduced intraoperative blood loss.

Our initial experiences with laparoscopic urologic surgery in a peripheral hospital in Central Java, Indonesia

Introduction: Nowadays, laparoscopic surgery in urology is widely adopted as a surgical technique for almost all cases, rendering the traditional open surgery approach obsolete. The increased use of laparoscopic surgical procedures has significantly contributed to progress in many urology areas. This study evaluates the initial experience with laparoscopic urology surgery in Banyumas General Hospital, a peripheral hospital in Indonesia. Method: Between May 2023 and October 2023, laparoscopic urologic surgery was performed on 36 patients. The patient’s demographic characteristics, pre-operative diagnosis, type of laparoscopic approach, and intraoperative and post-treatment results were gathered and analyzed retrospectively. Result: The mean patient age is 58.69±13.52 years, with 12 (33.33%) female patients and 24 (66.67%) male patients. While 20 had ureterolithotomy, 3 had pyelolithotomy, 5 had radical cystectomy, 2 patients received unroofing renal cyst, 1 had pyeloplasty, 1 had ureteral Anastomosis, and 1 had radical nephroureterectomy, 1 had a simple nephrectomy, 1 had diverticulectomy, and 1 had orchidopexy. 2 (5,56%) of the 36 patients must be converted to open surgery. The mean duration of surgery for procedures we did was as follows: ureterolithotomy 86.25 ± 7.23 minutes, pyelolithotomy 96.67 ± 7.64, radical cystectomy 418± 64.09 min, unroofing renal cyst 57.5 ± 10.61 minutes, pyeloplasty 130 minutes, ureteral anastomosis 220 minutes, radical nephroureterectomy 210 minutes, simple nephrectomy 140 minutes, diverticulectomy 215 minutes, and orchidopexy 125 minutes. The mean hospital stay was 4.39 ± 2.28 (2-11) days. There are major complications, but no mortality was encountered. Conclusion: Laparoscopic surgery is an effective technique with excellent outcomes, a safe and feasible alternative to open surgery in urology.

The Conversion Rate of Laparoscopic Cholecystectomy to Open Cholecystectomy at King Abdulaziz Medical City, Jeddah, Saudi Arabia: Prevalence and Causes.

Introduction Laparoscopic cholecystectomy has emerged as the preeminent surgical technique for cholecystectomy. However, in exceptional circumstances, surgeons may encounter significant obstacles that necessitate reverting to the traditional open approach, which has more undesirable complications. In this study, we aimed to identify the factors underlying conversion and to quantify its prevalence in the medical setting of King Abdulaziz Medical City (KAMC) in Jeddah to lower the rate of conversion. Methodology In this retrospective cross-sectional study, a non-probability consecutive sampling technique was utilized to include all patients over 16 years of age who underwent cholecystectomy at KAMC, Jeddah, between January 2009 and June 2022, excluding any patients with missing data. Results The total number of patients operated for cholecystectomy was 2,632, of which 1924 were female (73.1%) and 708 were males (26.9%). Of these patients, only 69 were converted to open (2.62%). Among them, 32 patients were in the age group >60, with the highest conversion rate (7.80%). The leading causes were adhesions in 55 cases (79.71%) and distorted anatomy in 31 cases (44.92%). Conclusion This study shows distorted anatomy and adhesions to be the leading causes of conversion from laparoscopic cholecystectomy to open approach at KAMC with a conversation rate of 2.62%. Furthermore, this article includes a higher number of patients in a longer period compared to other similar literature, which may give more accountable results that help reduce the conversion rate and complications.

Streamlining Iliac Bone Harvest for Maxillary Reconstruction With Novel Use of Arthrex Osteochondral Autograft Transfer System.

This study introduces a novel application of the Osteochondral Autograft Transfer System (OATS) for autologous bone grafting during alveolar cleft repair. Approximately 75% of patients with cleft lip and palate have an alveolar cleft, which often necessitates secondary bone grafting from common donor sites such as the iliac crest. Traditional harvesting techniques, although effective, can be labor-intensive and increase the risk of donor site injury. Here the authors describe the use of OATS, which has primarily been used in orthopedic procedures like anterior cruciate ligament reconstruction, for the first time in alveolar cleft repair. It involves a minimally invasive, single-use transfer system for harvesting osteochondral autografts from the anterior iliac crest, and thereby reduces harvest time compared with traditional open approaches. The procedure is detailed from pre-operative evaluation through long-term follow-up and highlights the technique's benefits related to surgical time, ease of use, and maintenance of sizable autograft volumes. Similarly, the authors discuss other advantages of OATS, including its single-use and cordless nature, which is believed to contribute to a lower contamination risk and better intraoperative ergonomics.

Retroperitoneal approach for ilio-superior mesenteric artery bypass: Technique and case series

In patients with chronic mesenteric ischemia, options for revascularization include endovascular angioplasty, stenting and open surgery, with the latter typically favored in patients who have failed or who are not candidates for endovascular intervention. Here we describe a retroperitoneal approach for open surgical revascularization in patients with a hostile abdomen. We present a case series of five patients from our institution. The median age was 72 years, the mean operative time was 143.6 minutes and 90-day mortality rate was 0. This case series demonstrates the technical feasibility, success, and safety of this approach in patients with anatomic factors that would render a traditional open surgical approach for revascularization technically difficult.

Can We Rely on Prophylactic Two-Level Vertebral Cement Augmentation in Long-Segment Adult Spinal Deformity Surgery to Reduce the Incidence of Proximal Junctional Complications?

Background and Objectives: Proximal junctional kyphosis (PJK) and failure (PJF), the most prevalent complications following long-segment thoracolumbar fusions for adult spinal deformity (ASD), remain lacking in defined preventive measures. We studied whether one of the previously reported strategies with successful results-a prophylactic augmentation of the uppermost instrumented vertebra (UIV) and supra-adjacent vertebra to the UIV (UIV + 1) with polymethylmethacrylate (PMMA)-could also serve as a preventive measure of PJK/PJF in minimally invasive surgery (MIS). Materials and Methods: The study included 29 ASD patients who underwent a combination of minimally invasive lateral lumbar interbody fusion (MIS-LLIF) at L1-2 through L4-5, all-pedicle-screw instrumentation from the lower thoracic spine to the sacrum, S2-alar-iliac fixation, and two-level balloon-assisted PMMA vertebroplasty at the UIV and UIV + 1. Results: With a minimum 3-year follow-up, non-PJK/PJF group accounted for fifteen patients (52%), PJK for eight patients (28%), and PJF requiring surgical revision for six patients (21%). We had a total of seven patients with proximal junctional fracture, even though no patients showed implant/bone interface failure with screw pullout, probably through the effect of PMMA. In contrast to the PJK cohort, six PJF patients all had varying degrees of neurologic deficits from modified Frankel grade C to D3, which recovered to grades D3 and to grade D2 in three patients each, after a revision operation of proximal extension of instrumented fusion with or without neural decompression. None of the possible demographic and radiologic risk factors showed statistical differences between the non-PJK/PJF, PJK, and PJF groups. Conclusions: Compared with the traditional open surgical approach used in the previous studies with a positive result for the prophylactic two-level cement augmentation, the MIS procedures with substantial benefits to patients in terms of less access-related morbidity and less blood loss also provide a greater segmental stability, which, however, may have a negative effect on the development of PJK/PJF.

Comparison of Clinical Outcomes Between Laparoscopic and Open Surgery in Colorectal Cancer Patients.

Our research compares the clinical results of open surgery versus laparoscopic surgery for colorectal malignancies. Our analysis focused on a database that included data on patients with colorectal cancer who had laparoscopic or open surgery for stages I to III at a prestigious healthcare institute in India. Two groups of 50 patients underwent laparoscopic and 50 underwent conventional open colorectal surgery (OCRS and LCRS, respectively) throughout the same time. Patient demographics, operation data, initial postoperative outcomes, follow-up appointments, pathology results, and cancer stages were examined. The LCRS group had a much longer operation time compared to the OCRS. Subjects in the LCRS group experienced a notably accelerated recovery after surgery. The hospital stay for the OCRS group was considerably longer compared to that in the LCRS group. Laparoscopic colorectal surgery is a reliable and convenient alternative to the traditional open approach, providing comparable oncological efficacy.
