Comparative Analysis of Monopolar Electrocautery and Ultrasonic Activated Scalpel in Laparoscopic Cholecystectomy: A Comprehensive Evaluation Using Clinical, Laboratory, and Imaging Techniques.

Introduction Laparoscopic cholecystectomy has long been the cornerstone of gallstone treatment. Both monopolar cautery and ultrasonically activated scalpel (UAS, also known as harmonic scalpel) have been employed in the dissection of the gallbladder from its fossa during laparoscopic cholecystectomy. Material and methods The prospective study was conducted in the Department of Surgery at Vivekananda Institute of Medical Sciences including 200 patients equally divided among the monopolar cautery and harmonic scalpel group. Patients were observed for 48 hours post-surgery, during which temperature and pain assessment were done. Acute phase reactants were measured during this period and compared with preoperative values. On the seventh day ultrasonography was done to look for the inflammatory changes. Results In a study involving 200 patients, the majority fell within the age bracket of 31 to 50 years, with females constituting the predominant demographic. Notably, patients who underwent surgery with a harmonic scalpel exhibited a reduced need for analgesics. Furthermore, the use of harmonic scalpels led to noteworthy alterations in acute phase reactants, including a significant decrease in the total leucocyte count (TLC) (p=0.03), neutrophils (p=0.005), and lymphocytes (p=0.02). Additionally, patients in the UAS group experienced a significantly lesser increase in erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) values (p=0.0001). Conversely, ultrasound imaging conducted on the seventh day post-surgery did not reveal any significant differences between the two groups. Conclusion Laparoscopic cholecystectomy performed with a harmonic scalpel is associated with a reduced tissue response and less tissue damage compared to the monopolar group.

Spray-Type Adhesion Barrier Enhances Safety and Feasibility of Robotic Repeat Liver Resection: Initial Experience and Outcomes.

Background Although various types of adhesion barriers are widely utilized in liver surgery, the safety and feasibility of their use during repeat robotic liver resection (R-RLR) are still unknown. Methods Among the 68 patients undergoing RLR with the application of the spray-type adhesion barrier at Kokura Memorial Hospital, Kitakyushu, Japan, between 2021 and 2023, 24 cases that underwent R-RLR were included in this study. The included patients were divided into two groups: those who underwent previous hepatectomy with the use of a spray-type adhesion barrier (R-RLR-B, n = 14) and those without its previous use (R-RLR-NB, n = 10). The perioperative outcomes were compared between the groups. Results There were no differences between the R-RLR-B and R-RLR-NB groups in background characteristics, difficulty scores, operative and console time, or surgical blood loss. Although no difference was found between the groups in the time required for adhesiolysis before the robotic operation, both the time required for robotic adhesiolysis (75 minutes vs. 58 minutes, p = 0.034) and total time for adhesiolysis (192 minutes vs. 141 minutes, p = 0.014) were significantly shorter in the R-RLR-B group than in the R-RLR-NB group. Otherwise, there was no conversion to open hepatectomy, no intraoperative transfusion of red blood cells, no cases of grade B or C post-hepatectomy liver failure, and no mortality in the whole cohort. Conclusions The spray-type adhesion barrier may not be associated with an increase in the incidence of postoperative complications, including bile leakage or intraperitoneal abscess. In addition, its application during the previous hepatectomy can facilitate a secure R-RLR with reduced time for adhesiolysis. Thus, the use of the spray-type adhesion barrier for R-RLR is safe, effective, and time efficient.

Comparison of two different electrosurgical devices in reduction mammoplasty: Monopolar electrocautery versus plasmakinetic cautery.

BACKGROUND: Many devices are used for dissection and hemostasis during reduction mammoplasty. While one of the most common methods is monopolar electrocautery, tissue damage due to thermal spread remains a controversial topic. New devices have been designed to minimize this effect. In this study, plasmakinetic cautery was hypothesized to reduce sensation loss, drainage, and wound-healing problems in reduction mammoplasty because it is less harmful to the surrounding tissues. METHODS: Sixty-eight patients were evaluated in a matched pair design, with random (blinded) assignment of 34 patients with conventional monopolar electrocautery (Group A) and 34 patients with plasmakinetic cautery (group B). Postoperative drainage volume, drain duration, nipple-areolar complex (NAC) sensation, and complications (dehiscence, seroma, ischemia, and nipple circulatory problems) were compared by the researcher, who was blinded to the device used for the patient. RESULTS: The groups were comparable in terms of age, body mass index (BMI), comorbidities, and medications (p > 0.05). The mean age of the patients were 38.50 ± 9.14 years in group A and 37.54 ± 8.17 in group B. The mean BMI was 25.19 ± 3.22 kg/m2 in group A and 25.65 ± 2.96 kg/m2 in group B. No differences were detected between the groups in terms of drain duration time, NAC sensation, or complications, but the drainage volume was statistically lower with plasmakinetic cautery (p < 0.05). CONCLUSION: The study findings indicate that the main advantage of plasmakinetic cautery in reduction mammoplasty was a decrease in drainage volume when compared with monopolar electrocautery.

Can alternative medical methods evoke somatosensory responses and functional improvement?

Background: Evidence-based scientific studies focusing on complementary alternative medicine (CAM) and potential functional improvement after an insult of the central nervous system are lacking. Aims: We aim to demonstrate that functional recovery after stimulation applied as a CAM treatment through cauterization might trigger neural repair and regenerative paths similarly as acupuncture, cupping, electrical or magnetic stimulations. Those paths are important in recovery of function. Procedures: Medical records and information of ten patients, with initial presentations of cerebral trauma or spinal cord insult inducing paralysis, were studied. Patients ages ranged from 17 to 95-year-old. Patients consulted for alternative medical treatment one year or more after initial diagnosis.CAM treatment consisted in 10-point stimulation on the skull and 4-point stimulation located at the right and left calves and forearms. Stimulations consisted of a heated steel rod application (cautery) in a one-time session. The duration of each stimulation was about 0.5 s. Results: Most studies using CAM stimulations (acupuncture, cautery, cupping, moxibustion, electrical and magnetic stimulations) describe improvement. In all 10 medical records and information from our practitioner, patients had improvement in their motor skills, including gain of weight support, unassisted small walks, independent and voluntary movements of limbs. Improvement was steady over a period of one to several years. Conclusion: We compared our findings to acupuncture, electrical, magnetic field effects to highlight common paths and to provide scientific evidence for recovery of the function. We believe that CAM treatments triggered existing or new neuronal networks as well as synaptic efficiency or reactivation, through highly increased, sensory nociceptive coupled to proprioceptive, afferences. Those results also highlight the need to further investigate neural function of cortical and subcortical areas through indirect pathways stimulations.

An Efficient Saline-Linked Cautery (SLiC) Method for Robotic Liver Parenchymal Transection Using Simultaneous Activation of Saline-Linked Cautery and Robotic Suctioning: Detailed Technical Aspects and Short-Term Outcomes.

Introduction While there are several advantages to utilizing robotics in liver surgery compared to traditional open and laparoscopic approaches, the most challenging part of robotic liver resection (RLR) remains the liver parenchymal transection. This is primarily due to the constraints of the existing robotic tools and the absence of a standard procedure. This study presents detailed technical aspects of our novel saline-linked cautery (SLiC) method for RLR and assesses the short-term outcomes for both non-anatomical and anatomical RLRs. Methods In this study, 82 cases that underwent RLR utilizing the SLiC method at our hospital from September 2021 to December 2023 were examined. A novel SLiC method is introduced in this study for robotically transecting the liver parenchyma utilizing bipolar cautery or monopolar scissors. The technique involves activating the SLiC and robotic suctioning simultaneously. The included patients were divided into two groups: patients undergoing robotic anatomical hepatectomy (n=39), and those receiving robotic non-anatomical hepatectomy (n=43). Short-term outcomes, including intraoperative and postoperative complications, were assessed in patients receiving both anatomical and non-anatomical hepatectomies. Results In the whole cohort, 74% of patients had performance status 1 or 2, and 24% were classified as Child-Pugh class B. RLR was performed without Pringle's maneuver in more than 80% of cases in patients receiving robotic non-anatomical hepatectomy, and more than 80% of patients undergoing robotic anatomical hepatectomy required only four or fewer 15-minute Pringle's maneuvers. There was no conversion to open hepatectomy, no cases of grade B or C post-hepatectomy liver failure, and no mortality in the entire cohort. Four postoperative complications with CDC IIIa or higher occurred (small bowel obstruction in two cases, intraabdominal hemorrhage in one, and bile leak in another), but no differences in the frequency of complications were found between those undergoing non-anatomical and anatomical hepatectomy (p=0.342). Conclusions The SLiC method, which involves simultaneously activating SLiC and robotic suctioning with either monopolar scissors or bipolar cautery, appears to be a secure and convenient technique for liver parenchymal transection in RLR. This innovative method permits precise access to the major Glissonean and venous structures within the liver, making RLR more standardized and easily applicable in routine patient care.

The value of oestrogen receptor, progesterone receptor and keratins 5 and 14 immunohistochemistry in the evaluation of epithelial proliferations at cauterised margins in breast-conserving surgery specimens.

In breast conservative surgery, it is sometimes difficult to decide whether the cauterised tissue at the inked margin represents normal / hyperplastic or neoplastic tissue. We retrospectively assessed the value of ER, PR, CK5 and CK14 IHC in clarifying the nature of cauterised tissues at the margins concerning 34 lesions of 23 patients. 27 cases belonged to lesions that could not be adequately classified on the basis of the HE stains. Two thirds of them could be classified as non-neoplastic or neoplastic and two thirds of the remaining could be favourised as neoplastic or non-neoplastic, with 3/27 cases remaining uncertain. All 4 IHC reactions were helpful in classifying the lesions in almost half of the cases. However, 3 or 4 immunostains were supportive of the classification in 19/27. The most useful stains were the keratins, generally demonstrating a matching pattern of cell labelling with CK5 and CK14. ER and PR were somewhat less useful in classifying uncertain lesions. Considering all the 27 questionable lesions, IHC with ER, PR, CK5 and CK14 clarified the lesions at the cauterised margins in 23 cases. Taken all these considerations into account, CK5, CK14, PR and ER IHC may help in distinguishing between cautery damaged neoplastic and non-neoplastic tissues. All four IHC may yield the best support for decision making, but CK5 and/or CK14 may be sufficient in their own. The essential approach is that the results must be interpreted with caution, in the context of the given patient's disease, to avoid misinterpretations.

Adverse events associated with the gold probe and the injection gold probe devices used for endoscopic hemostasis: A MAUDE database analysis.

BACKGROUND: Gastrointestinal (GI) bleeding accounts for over half a million admissions annually and is the most common GI diagnosis requiring hospitalization in the United States. Bipolar electrocoagulation devices are used for the management of gastrointestinal bleeding. There is no data on device-related adverse events for gold probe (GP) and injection gold probe (IGP). AIM: To analyze this using the Food and Drug Administration (FDA's) Manufacturer and User Facility Device Experience (MAUDE) database from 2013 to 2023. METHODS: We examined post-marketing surveillance data on GP and IGP from the FDA MAUDE database to report devicerelated and patient-related adverse events between 2013-2023. The MAUDE database is a publicly available resource providing over 4 million records relating to medical device safety. Statistical analyses were performed using IBM SPSS Statistics V.27.0 (IBM Corp., Armonk, NY, United States). RESULTS: Our search elicited 140 reports for GP and 202 reports for IGP, respectively, during the study period from January 2013 to August 2023. Malfunctions reportedly occurred in 130 cases for GP, and actual patient injury or event occurred in 10 patients. A total of 149 patients (74%) reported with Injection GP events suffered no significant consequences due to the device failure, but 53 patients (26%) were affected by an event. CONCLUSION: GP and IGP are critical in managing gastrointestinal bleeding. This study of the FDA MAUDE database revealed the type, number, and trends of reported device-related adverse events. The endoscopist and support staff must be aware of these device-related events and be equipped to manage them if they occur.

Managing recurrent nosebleeds in children: a retrospective review of 718 children attending a nurse-led epistaxis clinic.

OBJECTIVE: This review assessed the effectiveness of the nurse-led children's epistaxis clinic in streamlining patient care and avoiding unnecessary general anaesthesia. METHODS: A retrospective case note review was conducted of children attending the nurse-led epistaxis clinic between 2019 and 2021. RESULTS: A total of 718 children were seen over three years. Twelve (1.7 per cent) had a known coagulopathy. Of the children, 590 (82 per cent) had visible vessels and 29 (4 per cent) had mucosal crusting. Silver nitrate cautery was attempted under topical anaesthesia in 481 children, with 463 (96 per cent) successful cauterisations. Fifteen (3 per cent) were cauterised under general anaesthesia. Of the children, 706 (99 per cent) were prescribed nasal antiseptic preparations; this was the sole treatment for 58 (8 per cent). Blood investigations were requested for eight children (1 per cent) and haematology referral for three (0.4 per cent). CONCLUSION: This is the largest published series of children's nosebleeds. Given the short-lived benefit from cautery, it is suggested that general anaesthesia should not be offered routinely. However, improved haematology referral criteria are required to increase underlying diagnosis.

Feasibility and safety of bipolar radiofrequency track cautery during percutaneous image-guided abdominal biopsy procedures.

PURPOSE: The purpose of this study was to assess the feasibility and safety of using a bipolar radiofrequency track cautery device during percutaneous image-guided abdominal biopsy procedures in at-risk patients. METHODS: Forty-two patients (26-79 years old; female 44%) with at least one bleeding risk factor who underwent an abdominal image-guided (CT or US) biopsy and intended bipolar radiofrequency track cautery (BRTC) were retrospectively studied. An 18G radiofrequency electrode was inserted through a 17G biopsy introducer needle immediately following coaxial 18G core biopsy, to cauterize the biopsy track using temperature control. Bleeding risk factors, technical success, and adverse events were recorded. RESULTS: BRTC was technically successful in 41/42 (98%) of procedures; in one patient, the introducer needle retracted from the liver due to respiratory motion prior to BRTC. BRTC following percutaneous biopsy was applied during 41 abdominal biopsy procedures (renal mass = 12, renal parenchyma = 10, liver mass = 9, liver parenchyma = 5, splenic mass or parenchyma = 4, gastrohepatic mass = 1). All patients had one or more of the following risk factors: high-risk organ (spleen or renal parenchyma), hypervascular mass, elevated prothrombin time, renal insufficiency, thrombocytopenia, recent anticoagulation or anticoagulation not withheld for recommended interval, cirrhosis, intraprocedural hypertension, brisk back bleeding observed from the introducer needle, or subcapsular tumor location. No severe adverse events (grade 3 or higher) occurred. Two (2/41, 5%) mild (grade 1) bleeding events did not cause symptoms or require intervention. CONCLUSION: Bipolar radiofrequency track cautery was feasible and safe during percutaneous image-guided abdominal biopsy procedures. IRB approval: MBG 2022P002277.

Risk of Monopolar Electrosurgery in Cochlear Implant Recipients is Nominal: Evidence to Guide Clinical Practice.

OBJECTIVE: Comprehensively assess the prevalence of monopolar electrosurgery-related device complications among cochlear implant (CI) recipients. STUDY DESIGN: Multifaceted retrospective review and survey. SETTING: Tertiary medical center. METHODS: Multifaceted approach including: (i) review of the current literature; (ii) historical review of institutional data from an academic, tertiary CI center; (iii) review of industry data provided by 3 Food and Drug Administration-approved CI manufacturers; and (iv) survey of high-volume CI centers. RESULTS: Literature review identified 9 human studies, detailing 84 devices with 199 episodes of device-cautery exposure. From studies reporting on patients records, no implant showed evidence of damage after exposure. One cadaveric study using dental cautery reported 1 episode of device damage. Review of institutional records did not identify any CI damage in 84 instances of exposure. Data from the 3 major implant manufacturers showed a single report of damage that could be reasonably linked to monopolar electrosurgery, out of a possible 689,426 CIs. Last, a survey of 8 high-volume CI centers did not identify any adverse events associated with monopolar cautery. CONCLUSION: These data estimate the risk of adverse device-related events or tissue injury to be extraordinarily low. Short of operating in immediate proximity to the CI (ie, the ipsilateral temporoparietal scalp), these data indicate that monopolar electrosurgery can be used in the body and the head-and-neck of CI recipients with nominal risk. These findings may guide decision-making in cases that are optimally or preferably performed with monopolar electrocautery and can be used to counsel CI patients following inadvertent exposures.

Comparing recurrence between cautery techniques in pediatric epistaxis.

OBJECTIVE: To compare the risk of recurrent epistaxis between children treated with silver nitrate (SN) in the office or electrocautery (EC) in the operating room (OR). METHODS: Patients aged 2-18 diagnosed with epistaxis (ICD R04.0) in 2018 and treated with SN or EC were retrospectively reviewed. Epistaxis laterality, history of nasal trauma, and personal or family history of a bleeding disorder were recorded. Patients with prior cautery or epistaxis secondary to a procedure were excluded. Recurrence was defined as initial encounter after cautery with documented epistaxis. Patients were followed up into 2022 to track onset of recurrence. Time to recurrence between SN and EC was compared with hazard curves with predictors for recurrence analyzed via Cox's proportional hazard regression. RESULTS: Among 291 patients cauterized for epistaxis, 62 % (n = 181) received SN compared to 38 % (n = 110) who underwent EC. There was significantly higher risk of recurrence when treated with SN compared to EC (Hazard ratio 2.45, 95 % CI: 1.57-3.82, P < 0.0001). Median time to recurrence was not statistically different between techniques (6.39 months (SN) (IQR: 2.33, 14.82) vs. 4.11 months (EC) (IQR: 1.18, 20.86), P = 0.4154). Complication rates were low for both groups (1.16 % (SN) vs. 0 % (EC), P > 0.05). CONCLUSION: Among patients with epistaxis, risk of recurrence is significantly higher in those cauterized with SN compared to EC. Time to recurrence is not significantly different between cautery techniques.

Management of ingrowing nail.

For decades, there has been debate about the cause of ingrown nail: is the nail plate or the periungual tissue at fault? There is no consensus and management relies on case-by-case analysis followed by tailored treatment. Conservative treatment should be attempted in children when the cause is transient (e.g., poor clipping) or the patient refuses surgery. Surgical treatments rely on two main approaches: either narrowing the nail plate, or debulking the soft tissue. It is up to the surgeon to select the most appropriate approach in each case. All procedures discussed in this chapter have high cure rates as long as they are properly performed. As with all surgical procedures, they are operator-dependent. Chemical cautery is the easiest and most versatile technique that may help in almost all instances for lateral ingrowth. For distal ingrowth and very hypertrophic and exuberant lateral folds, debulking with primary or secondary healing is most effective.

Eight years experience of transanal endoscopic microsurgery

Introduction: Transanal Endoscopic Microsurgery (TEM) is a minimally invasive method for management of different proctologic conditions. Despite widespread use of this method, it is not used widely in Iran. This report is about to describe the application of TEM in managing different proctologic conditions in a tertiary colorectal referral center in Iran regarding methods and complications. Methods: All of the patients' documents such as procedure, method, early postop complications and further operations were actively reviewed and the data were entered in to the database. Results: Since 2012 till the end of 2020 chart review was done and 150 cases of TEM operation were found. The most frequent procedure that was done was resection procedure. Using different energy devices during surgery or suturing versus not suturing the defect were not associated with complication. There was a case of in hospital mortality and one case delayed perianal fistula following TEM. Measurement of lesion distance from anal verge was not significantly different using TEM or colonoscopy. Villous adenomas detected in colonoscopy were mostly associated with malignancy. In evaluated resected lesions most of cases had free base and distance from anal verge or using different energy devices were not associated with obtaining free base. Conclusion: TEM is a safe minimal invasive procedure with acceptable complications that could be helped in managing different proctologic conditions and the results of reviewing our patients revealed the same results that is reported from other colorectal centers.

Comparison of Three Tonsillectomy Techniques: Cold Dissection, Monopolar Electrocautery, and Coblation.

Introduction Tonsillectomy is among the most common otolaryngological surgeries. Objective To evaluate and compare three tonsillectomy techniques: cold steel dissection (CSD), monopolar electrocautery (MEC), and coblation. Methods The present study retrospectively reviewed the medical records of patients who underwent tonsillectomy between January 2014 and January 2016. Postoperative visual analog scale (VAS) pain scores, analgesic use, surgical duration, time to return to normal activity, and postoperative bleeding status were noted. Results The CSD group had less analgesic use and shorter return to normal activity than the MEC group ( p = 0.037 and p < 0.001, respectively). The coblation group had lower VAS pain scores than the MEC group only at 1 hour to 4 hours postsurgery ( p < 0.016). The postoperative bleeding rate was similar in all groups ( p = 0.096). Conclusion Cold steel dissection tonsillectomy is associated with less postoperative pain and shorter recovery than MEC. Coblation is better than MEC in terms of postoperative pain at 1 hour to 4 hours only, whereas CSD is associated with less postoperative pain than coblation at 2 days to 7 days.

The Effectiveness of Chemical Cautery and Electrosurgery on Anogenital Wart: Systematic Review.

Introduction: Anogenital warts (AGW) is one of the sexually transmitted infections (STIs) caused by human papillomavirus (HPV). Treatment modalities of AGW yield low clearance and recurrence rate, so that chemical cautery with trichloroacetic acid (TCA) and electrosurgery are widely used to remove the lesions without any severe side effects. Objective: To investigate the efficacy of chemical cautery with TCA and electrosurgery in AGW based on clinical trials or case series. Methods: The systematic review was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) but not registered to the International Prospective Register of Systematic Review (PROSPERO). To acquire proper and accurate information from relevant literature, two databases PubMed and the Cochrane Library were searched from January 2013 to March 2023. Results: Thirteen studies were included in this systematic review, comprising seven articles on chemical cautery and six electrosurgery articles. The highest cure rate of chemical cautery with TCA was 94.1% while electrosurgery was 100%. A relatively low recurrence rate during 1 year follow-up was observed in electrosurgery with 14.6%, whereas the chemical cautery was 27.6%. Conclusion: Electrosurgery for AGW treatment had higher cure rate with lower recurrence rate compared to chemical cautery with TCA. Numerous adverse effects of electrosurgery were reported include bleeding and scar formation as high risk of HPV infection.

The Usefulness and Reliability of Coagrasper for Artery Bleeding during Endoscopic Necrosectomy.

Although endoscopic necrosectomy (EN) is a less invasive therapy for walled-off necrosis (WON), arterial bleeding can occur during EN. A 60-year-old man with infected WON underwent the EN procedure. During EN, the artery in the WON cavity was injured. As the artery was directly visible, we grasped it using a Coagrasper and coagulated the bleeding point. However, the bleeding was aggravated after coagulation owing to an extension of the vessel damage. The entire vessel was grasped, and complete hemostasis was achieved. The Coagrasper is useful for managing arterial bleeding; however, it should be employed only on the basis of its characteristics and in suitable scenarios.

Ensayo clínico controlado aleatorio de dos técnicas quirúrgicas para pterigión primario en pacientes de la selva: cauterización versus sutura / Randomized Controlled Clinical Trial of Two Surgical Techniques for Primary Pterygium in Jungle Patients: Cauterization versus Suturing

RESUMEN Objetivo: Comparar dos técnicas quirúrgicas para extirpar el pterigión, mediante la evaluación de la sintomatología postoperatoria y la incidencia de la recidiva. Métodos: Ensayo clínico controlado aleatorizado con dos grupos paralelos y diseño simple ciego en 80 pacientes con pterigión primario de la Clínica Oftalmológica de la Selva. El primer grupo consideró la técnica de autoplastia fijada con cauterio bipolar (n=40) y el segundo la técnica convencional de autoplastia fijada con puntos (n=40). Se evaluaron los síntomas a las 72 horas postoperatorias y la recidiva a los seis meses. Resultados: A las 72 horas postcirugía el 6 % de los operados con la técnica electrocauterio presentaron sintomatología en comparación a un 41 % de los operados con sutura (p<0,05). Se evidenció recurrencia de 1 caso en el grupo de electrocauterio y 4 en el grupo de sutura (2,5 % vs. 10 %, p<0,05). Conclusiones: La técnica con cauterio demostró una recuperación más favorable, con menor sintomatología y recurrencia en comparación a la técnica convencional. Estos hallazgos sugieren que la técnica con cauterio puede ser más efectiva y mejor tolerada en pacientes de este estudio.

ABSTRACT Objective: To compare two surgical techniques for excising pterygium, by evaluating postoperative symptoms and the incidence of recurrence. Methods: Randomized controlled clinical trial with two parallel groups and a single-blind design involving eighty patients with primary pterygium from the Ophthalmological Clinic of the Jungle. The first group considered the autograft fixation technique with bipolar cautery (n=40), and the second group considered the conventional autograft fixation technique with sutures (n=40). Symptoms were assessed at 72 hours postoperatively, and recurrence was evaluated at six months. Results: At 72 hours post-surgery, 6% of patients operated with the electrocautery technique exhibited symptoms, compared to 41% of those operated with sutures (p < 0.05). Recurrence was observed in 1 case in the electrocautery group and 4 in the suture group (2.5% vs. 10%, p < 0.05). Conclusions: The cautery technique demonstrated a more favorable recovery, with fewer symptoms and recurrence compared to the conventional technique. These findings suggest that the cautery technique may be more effective and better tolerated in patients in this study.

Heat treatment for giant cell tumors of bone: A systematic review.

This systematic review evaluates the effects of heat treatments in de novo, residual and recurrent giant cell tumors of bone (GCTB). Studies were eligible for inclusion if one of the following treatments was administered: radiofrequency ablation (RFA), microwave ablation, argon cauterization, electrocauterization and hot liquid treatment. The primary outcome was recurrence. Secondary outcomes were complications, pain, function, and quality of life. Recurrence rates for microwave ablation as an adjuvant to intralesional curettage were 0%, 4% and 10% (3 retrospective single-group studies); for argon cauterization 4%, 8% and 26% (3 cohort studies); electrocauterization 0% to 33% (8 cohort studies); and hot liquid 9.5% and 24% (2 cohort studies). Follow-up was generally ≥24 months. Data on pain, function and quality of life were scarce. Complications included infection and secondary osteoarthritis. Current evidence does not demonstrate or exclude an effect of heat treatments on recurrence in GCTB. Further research should objectify if (subgroups of) patients benefit from these treatments.

Comparison of trans-gastric vs trans-enteric (trans-duodenal or trans-jejunal) endoscopic ultrasound guided gallbladder drainage using lumen apposing metal stents.

BACKGROUND: Endoscopic ultrasound guided gallbladder drainage (EUS-GBD) is being increasingly used in practice (either as a bridge to cholecystectomy in high-risk patients or as destination therapy in non-surgical patients). Stents are used to create a conduit between the lumen of the gallbladder (GB) and the intestinal lumen through the gastric or enteric routes. Among the various types of stents used, cautery-enhanced lumen apposing metallic stents (LAMS) may be associated with fewer adverse events (AEs). AIM: To compare the clinical success, technical success, and rate of AEs between transgastric (TG) and trans-enteric [transduodenal (TD)/transjejunal (TJ)] approach to GB drainage. Further, we analyzed whether using cautery enhanced stents during EUS-GBD impacts the above parameters. METHODS: Study was registered in PROSPERO (CRD42022319019) and comprehensive literature review was conducted. Manuscripts were reviewed for the data collection: Rate of AEs, clinical success, and technical success. Random effects model was utilized for the analysis. RESULTS: No statistically significant difference in clinical and technical success between the TD/TJ and TG approaches (P > 0.05) were noted. There was no statistically significant difference in the rate of AEs when comparing two-arm studies only. However, when all studies were included in the analysis difference was almost significant favoring the TD/TJ approach. When comparing cautery-enhanced LAMS with non-cautery enhanced LAMS, a statistically significant difference in the rate of AEs was observed when all the studies were included, with the rate being higher in non-cautery enhanced stents (14.0% vs 37.8%; P < 0.01). CONCLUSION: As per our study results, TD/TJ approach appears to be associated with lower rate of adverse events and comparable efficacy when compared to the TG approach for the EUS-GBD. Additionally, use of cautery-enhanced LAMS for EUS-GBD is associated with a more favorable adverse event profile compared to cold LAMS. Though the approach chosen depends on several patient and physician factors, the above findings could help in deciding the ideal drainage route when both TG and TD/TJ approaches are feasible.

Gastric Explosion While Using Electric Cautery During Gastrojejunostomy: A Case Report.

Gastrointestinal gases become combustible when several gases reach a certain concentration. This occurs in situations where the gastrointestinal tract is obstructed for a certain amount of time. Hence, we present this case of a gastric explosion in a patient while performing a gastrojejunostomy. The reason underlying this combustion involved concomitant chronic pyloric stenosis. Operative procedures should include this information to enhance the safety of the patient and the surgical team.
