Transferability of laparoscopic skills acquired from three-dimensional high-definition and ultra-high definition endovision system to two-dimensional high-definition endovision system: an ex-vivo randomized study.

Three-dimensional high-definition (3D HD) and ultra-high-definition (4 K HD) endovision systems are rapidly adopted in academic setting. However, transferability of laparoscopic skills acquired from these systems to two-dimensional high-definition (2D HD) endovision system is not known. Forty stereo-enabled surgical residents were randomized into two groups. They performed three standardized surgical tasks, Task 1(Peg transfer), Task 2(Precision touch on uneven surface) and Task 3(Surgical knotting on rubber tube) for 15 repetitions using either 3D HD or 4 K HD. Both groups then performed the same tasks using 2D HD for 5 repetitions. Their performances were evaluated for execution time (speed) and error scores (safety). The residents in 3D HD group performed all three tasks significantly faster than residents in 4 K HD group with comparable error scores. The time taken to complete the tasks on 2D HD were comparable between residents trained in 3D HD and 4 K HD in two out of three tasks (p = 0.027, P = 0.115, p = 0.368 in task 1, 2 and 3 respectively). However, in two out of three tasks, residents trained on 3D HD committed significantly more errors than residents trained on 4 K HD (p < 0.0001, p < 0.001 in task 1 and task 2 respectively). Skill acquired on 4 K HD seems transferable to 2D HD environment. Participants trained in 3D HD made more errors while performing the tasks in 2D HD. It may be prudent to offer additional training on 2D HD to residents trained on 3D HD for safer laparoscopic surgical practice.

Low-pressure pneumoperitoneum with deep neuromuscular blockade versus standard pressure pneumoperitoneum in patients undergoing laparoscopic cholecystectomy for gallstone disease: a non-inferiority randomized control trial.

BACKGROUND: Low-pressure pneumoperitoneum (LPP) is an attempt at improving laparoscopic surgery. However, it has the issue of poor working space for which deep neuromuscular blockade (NMB) may be a solution. There is a lack of literature comparing LPP with deep NMB to standard pressure pneumoperitoneum (SPP) with moderate NMB. METHODOLOGY: This was a single institutional prospective non-inferiority RCT, with permuted block randomization of subjects into group A and B [Group A: LPP; 8-10 mmHg with deep NMB [ Train of Four count (TOF): 0, Post Tetanic Count (PTC): 1-2] and Group B: SPP; 12-14 mmHg with moderate NMB]. The level of NMB was monitored with neuromuscular monitor with TOF count and PTC. Cisatracurium infusion was used for continuous deep NMB in group A. Primary outcome measures were the surgeon satisfaction score and the time for completion of the procedure. Secondarily important clinical outcomes were also reported. RESULTS: Of the 222 patients screened, 181 participants were enrolled [F: 138 (76.2%); M: 43 (23.8%); Group A n = 90, Group B n = 91]. Statistically similar surgeon satisfaction scores (26.1 ± 3.7 vs 26.4 ± 3.4; p = 0.52) and time for completion (55.2 ± 23.4 vs 52.5 ± 24.9 min; p = 0.46) were noted respectively in groups A and B. On both intention-to-treat and per-protocol analysis it was found that group A was non-inferior to group B in terms of total surgeon satisfaction score, however, non-inferiority was not proven for time for completion of surgery. Mean pain scores and incidence of shoulder pain were statistically similar up-to 7 days of follow-up in both groups. 4 (4.4%) patients in group B and 2 (2.2%) in group A had bradycardia (p = 0.4). Four (4.4%) cases of group A were converted to group B. One case of group B converted to open surgery. Bile spills and gallbladder perforations were comparable. CONCLUSION: LPP with deep NMB is non-inferior to SPP with moderate NMB in terms of surgeon satisfaction score but not in terms of time required to complete the procedure. Clinical outcomes and safety profile are similar in both groups. However, it could be marginally costlier to use LPP with deep NMB.

Long-term outcomes of laparoscopic Heller's myotomy with angle of His accentuation in patients of achalasia cardia.

BACKGROUND: Laparoscopic Heller's myotomy (LHM) is an established treatment for achalasia cardia. Anti-reflux procedures (ARP) are recommended with LHM to reduce the post-operative reflux though the optimal anti-reflux procedure is still debatable. This study reports on the long-term outcomes of LHM with Angle-of-His accentuation (AOH) in patients of achalasia cardia. METHODS: One hundred thirty-six patients of achalasia cardia undergoing LHM with AOH between January 2010 to October 2021 with a minimum follow-up of one year were evaluated for symptomatic outcomes using Eckardt score (ES), DeMeester heartburn (DMH) score and achalasia disease specific quality of life (A-DsQoL) questionnaire. Upper gastrointestinal endoscopy, high resolution manometry (HRM) and timed barium esophagogram (TBE) were performed when feasible and rates of esophagitis and improvement in HRM and TBE parameters evaluated. Time dependent rates of success were calculated with respect to improvement in ES and dysphagia-, regurgitation- and heartburn-free survival using Kaplan-Meier analysis. RESULTS: At a median follow-up of 65.5 months, the overall success (ES ≤ 3) was 94.1%. There was statistically significant improvement in ES, heartburn score and A-DsQoL score (p < 0.00001, p = 0.002 and p < 0.00001). Significant heartburn (score ≥ 2) was seen in 12.5% subjects with 9.5% patients reporting frequent PPI use (> 3 days per week). LA-B and above esophagitis was seen in 12.7%. HRM and TBE parameters also showed a significant improvement as compared to pre-operative values (IRP: p < 0.0001, column height: p < 0.0001, column width: p = 0.0002). Kaplan-Meier analysis showed dysphagia, regurgitation, and heartburn free survival of 75%, 96.2% and 72.3% respectively at 10 years. CONCLUSIONS: LHM with AOH gives a lasting relief of symptoms in patients of achalasia cardia with heartburn rates similar to that reported in studies using Dor's or Toupet's fundoplication with LHM. Hence, LHM with AOH may be a preferred choice in patients of achalasia cardia given the simplicity of the procedure.

Illness wellness scale: novel grading system for performance status of patients under surgical care.

BACKGROUND: Grading the illness using clinical parameters is essential for the daily progress of inpatients. Existing systems do not incorporate these parameters holistically. The study was designed to internally validate the illness wellness scale, based upon clinical assessment of the patients requiring surgical care, for their risk stratification and uniformity of communication between health care providers. METHODS: Prospective observational study conducted at a tertiary care hospital. An expert panel devised the scale, and it was modified after feedback from 100 health care providers. A total of 210 patients (150 for internal validation and 60 for inter-observer variability) who required care under the department of surgical disciplines were enrolled. This included patients presenting to surgery OPD, admitted to COVID/non-COVID surgical wards and ICUs, aged ≥16 years. RESULTS: The response rate of the final illness wellness scale was 95% with 86% positive feedback and a mean of 1.7 on the Likert scale for ease of use (one being very easy and five being difficult). It showed excellent consistency and minimal inter-observer variability with the intra-class correlation coefficient (ICC) above 0.9. In the internal validation cohort (n = 150), univariate and multivariable analysis of factors affecting mortality revealed that categorical risk stratification, age ≥ 60 years, presence or absence of co-morbidities especially hypertension and chronic kidney disease significantly affect mortality. CONCLUSIONS: The Illness wellness scale is an effective tool for uniformly communicating between health care professionals and is also a strong predictor of risk stratification and mortality in patients requiring surgical care.

Age adjusted Charlson comorbidity index (a-CCI) AS a tool to predict 30-day post-operative outcome in general surgery patients.

INTRODUCTION: Age adjusted Charlson comorbidity index (a-CCI) is an established scoring system to predict long-term mortality. However, its role in predicting 30-day post-operative outcome in general surgery patients is not well elucidated. METHODS: This was a prospective observational study. Consecutive patients operated under general anaesthesia between January 2019 and December 2020 were enrolled. Their a-CCI was calculated and stratified as Grade 0 comorbidities (a-CCI score = 0), Grade A comorbidities (a-CCI score = 1 and 2) and Grade B comorbidities (a-CCI score ≥ 3). Post-operative complications were graded according to Clavien Dindo (CD) grading system and classified as minor complications (CD Grades I and II), major complications (CD Grades III-IV) and mortality (CD Grade V). Binary logistic regression and multi-nominal logistic regression analysis were done and relative risk ratios were calculated. RESULT: A total of 925 patients were enrolled. The mean age was 42.75 (14-85 ± 10) years. 31% of our patients had complications within 30 days of surgery which included mortality in 2.7%. Compared with patients with Grade 0 comorbidities, the odds of getting complications is 1.2 times more in patients with Grade A comorbidities and 1.84 times more in patients with Grade B comorbidities (P = 0.205, 0.001 respectively). In comparison to patients with Grade 0 co-morbidities, risk of mortality is 3 and 17.86 times more in patients with Grade A and Grade B comorbidities (P = 0.121 and < 0.001 respectively). CONCLUSION: a-CCI has clinical relevance in general surgical patients and can predict early post-operative outcome. It should be a part of our armamentarium for pre-operative assessment of surgical patients.

Late Local and Distant Recurrence of Apparently Benign Paraganglioma.

Paraganglioma-pheochromocytoma (PPGLs) are relatively rare catecholamine-secreting tumors of chromaffin origin. Due to the sympathetic effects of catecholamine excess, their presentation may range from non-specific symptoms to dangerous hypertensive crises. We present the case of a 36-year-old lady with recurrent paraganglioma (PGL) who presented in emergency with hypertensive crisis. She had a history of surgery for left-sided PGL 18 years earlier. Imaging showed local recurrence with pulmonary metastases and blood biochemistry showed raised urinary metanephrines. In view of her poor general condition, we undertook a staged surgical approach for management. She first underwent en-bloc excision of recurrent PGL with left nephrectomy. Nine weeks later, she underwent a pulmonary metastasectomy. This staged surgical approach resulted in the stabilization of blood pressure and normalization of urinary catecholamine. Although most of these tumors are indolent by nature, this case highlights the metastatic potential of apparently benign PGL. This case explores the possibility of a staged surgical approach in a high-risk patient and emphasizes the need for long-term follow-up in these cases.

Performance of three-dimensional and ultra-high-definition (4K) technology in laparoscopic surgery: A systematic review and meta-analysis.

Background: The technology in the field of laparoscopy is rapidly evolving and is primarily focussed on increasing the quality of image and depth perception in the form of 4K and three-dimensional (3D) technology. There has been no conclusion yet regarding the better technology. Methods: A systematic search was performed independently by two authors across MEDLINE, Google Scholar and Embase using the PRISMA guidelines. All randomised control trials comparing 3D and 4K technologies were included. Meta-analysis was conducted using random-effects statistics for time taken for different tasks across the studies. Results: The search strategy revealed a total of 1835 articles, out of which nine studies were included. Three studies showed no superiority of 3D over 4K, while the remaining six did. Meta-analysis for the time taken for peg transfer favoured 3D over 4K (overall effect: Z = 2.12; P = 0.03). Forest plots for time taken for suturing (Z = 1.3; P = 0.19) and knot tying (Z = 1.7; P = 0.09) also favoured 3D over 4K; the results however were statistically insignificant. Path length was reported by two studies and was found to be lesser in the 3D group. Two studies measured the workload by NASA/Surg-TLX score, which was lower in the 3D group. Visual side effects were found to be higher in the 3D group. Conclusion: 3D technology is likely to result in a shorter operative time and better efficiency of movement as compared to the 4K technology by the virtue of its better depth perception.

Comparison of three-dimensional (3D) endovision system versus ultra-high-definition 4K endovision system in minimally invasive surgical procedures: a randomized-open label pilot study.

BACKGROUND: Experimental work comparing 3-Dimensional (3D) and 4K ultra-high-definition endovision system (4K) indicates that the latter with double the resolution of standard 2D high-definition systems may provide additional visual cues to compensate for the lack of stereoscopic vision. There is paucity of studies comparing 3D and 4K system in clinical settings. This randomized study compares 3D and 4K systems in three laparoscopic procedures of increasing complexity. METHODS: 139 patients undergoing laparoscopic cholecystectomy (60 patients), transabdominal preperitoneal (TAPP) repair (49 patients) and laparoscopic Heller's cardiomyotomy with anti- reflux procedure (30 patients) between May 2018 and February 2020 were randomized to undergo surgery using either 3D or 4K systems. Primary objective was to measure total operative time. Secondary objectives were to compare workload perceived by surgeons using SURG-TLX and surgeon satisfaction score. Timings of key surgical steps and peri-operative course of the patients was also recorded. Data were analyzed using Stata Corp. 2015. RESULTS: Patients undergoing surgery with 3D and 4K systems were comparable in their clinical and demographic profiles. The mean total operative time in 3D and 4K groups was comparable in cholecystectomy (52.7 vs 56.2, p = 0.50), TAPP (63.8 vs 69.6, p = 0.25) and Heller's cardiomyotomy (124.7 vs 143.3, p = 0.14) with faster hiatal dissection in 3D group (8 min, p = 0.02). Operative time was better in patients undergoing Heller's myotomy with Angle of His accentuation with 3D by 28 min (p = 0.03). Total workload was similar in 3D and 4K groups in all the procedures but mental & physical demand was lower in 3D group in Heller's cardiomyotomy (p = 0.03, p = 0.01), Surgeon satisfaction score was comparable in all three procedures. CONCLUSION: Overall, 3D HD and 4K systems are comparable in performing laparoscopic cholecystectomy, TAPP and Heller's Cardiomyotomy. Hiatal dissection time, mental and physical task load was better with 3D in Heller's Cardiomyotomy.

Thoracoscopic enucleation of a large esophageal leiomyoma in the lower esophagus: challenges and solutions.

Esophageal leiomyomas are rare tumors which have been conventionally managed using open surgery. Only few reports describe the enucleation of large or circumferential leiomyoma successfully managed by thoracoscopy. We herein describe a case of a large circumferential esophageal leiomyoma successfully enucleated using thoracoscopy. An asymptomatic 28-year-old gentleman was diagnosed with a posterior mediastinal mass on a screening chest radiograph. On further investigations with computerized tomography scan and endoscopy, he was diagnosed to have a circumferential homogenous 7×5 cm submucosal lesion in the lower end of the esophagus. Magnetic resonance imaging was performed to rule out duplication cyst and positron emission scan to rule out malignancy in view of suspicious features on endoscopic ultrasound. The final provisional diagnosis was benign lesion of the esophagus. Biopsy of tumor was avoided preoperatively to decrease the chances of intraoperative mucosal injury. The patient was planned for a thoracoscopic enucleation. The tumor was enucleated with meticulous dissection in the submucosal plane with use of stay sutures and minimal use of cautery. There was a pinpoint mucosal perforation which was repaired. The integrity of repair was checked using methylene blue insufflation test and endoscopy. The patient had an uneventful recovery with postoperative gastrografin showing no leak or stricture. Conclusively, a large esophageal leiomyoma may be safely enucleated thoracoscopically with meticulous dissection.

Effect of Short-term-focused Training on a Phantom Model in Improving Operative Room Performance Among Surgical Residents: A Randomized Trial.

BACKGROUND: Meta-analysis has shown the effectiveness of various training methods for the acquisition of laparoscopic skills in surgical training. However, there is very limited literature focusing on the translation of skill acquisition on training models into improved operating room (OR) performance. This study was conducted to evaluate the effectiveness of the Tuebingen trainer with integrated Porcine tissue in improving OR the performance of surgical trainees using standard assessment tools. MATERIALS AND METHODS: The study was a single-blinded double-armed randomized control study conducted between July 2016 and March 2018. Eighteen, fourth, and fifth semesters of surgery residents were included in the study. The baseline performance was assessed in OR by performing laparoscopic cholecystectomy using validated scores, that is, Global Operative Assessment of Laparoscopic Skills (GOALS), Additional Five Criteria, Task-specific Checklist, Error Checklist, Visual Analogue Scale. The residents were then randomized into trainee and nontrainee groups. The training group received 5 days of short-term-focused training on the Tuebingen trainer, and the improvement was reassessed in OR. RESULTS: The demographic profile of residents was similar. The baseline scores were comparable. The training group showed statistically significant improvement in GOALS (9.88±1.76 to 12±0.66, P=0.05 vs. 10.33±1.5 to 11.4±2.24, P=0.28), task-specific checklist (42.22±10.92 to 53.33±14.14, P=0.027 vs. 45.55±10.13 to 50±17.32, P=0.51), and error checklist. The operating time significantly reduced (36.0±4.03 vs. 50.44±11.39, P=0.0025) following training. CONCLUSIONS: Our study concludes that the training on the Tuebingen trainer with integrated porcine organs results in a statistically significant improvement in the OR performance of surgical residents as compared with the nontrained residents, thereby indicating a transfer of skills from training to OR.

Learning Pattern of Two-Dimensional, Three-Dimensional, and Ultra-High-Definition Endovision System on Standardized Phantom Tasks: An Ex Vivo Randomized Study.

Introduction: Three-dimensional (3D), high-definition (HD), and ultra-high-definition (4K HD) are recent additions over regular HD technology for laparoscopic surgery. The aim of this study was to evaluate the learning pattern of these systems on standardized phantom tasks. Methodology: Forty-five stereo-enabled resident doctors were randomly assigned into three groups. They performed three validated tasks, precision touch on flat surface, precision touch on uneven surface, surgical knot on rubber tube using either two-dimensional (2D) HD, 3D HD, or 4K HD Endovision systems. Each task was repeated 20 times. Data from four consecutive repetitions were pooled to make five blocks. Split group analysis by comparing the consecutive blocks in execution time and errors were made to see the learning pattern. A significant difference was accepted as continuous learning while no significant difference was accepted as learning stabilization. Result: Operating time was stabilized in two tasks after third block in 2D HD, one task after fourth block in 4K HD. There was continuous learning in all tasks with 3D HD. The 3D HD group was significantly faster than 2D HD and 4K HD in most of the tasks on fifth block. The error scores were similar between the consecutive blocks in 4K HD. It was stabilized after second block in 2D HD group and third block on 3D HD. Conclusion: The 3D HD Endovision system has more potential of faster execution of a task, but need more practice to reach similar safety profile. The 4K HD reached the safety plateau with minimal repetitions.

Thoracolaparoscopic repair of diaphragmatic hernias.

Complex long-standing diaphragmatic hernia presenting in adults is often managed through an open approach. Minimal invasive approach by either laparoscopy or thoracoscopy is limited by its ability to tackle these complex hernias with large defects and thoraco-mediastinal adhesions. Thus, standard laparoscopic or thoracoscopic approach is associated with high conversion to open approach. We herein describe a novel combined thoraco-laparoscopic approach to repair complex diaphragmatic hernias in a series of three adults.

Laparoscopic total mesorectal excision for rectal venous malformation: A case report with a brief literature review.

Rectal vascular malformation is a rare disease on which few reports have been published. Here, we report the case of a 38-year-old woman who presented with severe weakness, dyspnea, and recurrent episodes of rectal bleeding. Her colonoscopy showed an extensive pigmented lesion in the lower rectum. CT angiography showed diffuse circumferential wall thickening of the rectum, perirectal fat stranding, tiny round foci of calcification, and no arterial feeders. Multiphasic MRI confirmed the diagnosis. The patient underwent a total mesorectal excision with hand-sewn coloanal anastomosis. The venous malformation was confined to the mesorectal tissue. The avascular plane between the ectodermal and mesodermal tissue was well maintained. Blood loss was 200 mL. The patient has had no recurrence of disease in the 18 months since surgery. Although total mesorectal excision is described for rectal cancer, it may be indicated for benign disease like rectal vascular malformation to achieve complete removal of the disease and to minimize intraoperative blood loss.

Comparison of two-dimensional high-definition, ultra high-definition and three-dimensional endovision systems: an ex-vivo randomised study.

BACKGROUND: Two-dimensional high-definition (2D HD) endovision system is preferred for laparoscopic surgery. Recently, new generation three-dimensional (3D) HD and ultra-HD (4K) endovision systems are introduced to improve the safety and efficacy of laparoscopic surgery. There is limited evidence on superiority of one technology over the others. This experimental trial was designed to evaluate 2D HD, 3D HD and 4K HD endovision systems in performance of standardized tasks. METHODS: This was a randomized, cross-over experimental study. Twenty-one surgical residents who were exposed to laparoscopic surgery were enrolled. Participants were randomly assigned into three groups. Each group performed standardised tasks i.e. peg transfer, precision cutting, navigating in space and intra-corporeal suturing using 2D HD, 4K HD and 3D HD endovision systems on a box trainer. Procedures were recorded as 2D HD videos and analysed later. Participant's perceived workload was assessed using Surg-TLX questionnaire. Primary endpoints were execution time in seconds and error score. Secondary endpoint was workload assessment. RESULTS: The 3D HD had shorter execution time compared to 2D HD and 4K HD in all tasks except precision cutting (p = 0.004, 0.03, 0.001, 0.001 and p = 0.002, 0.191, 0.006, 0.005 in peg transfer, precision cutting, navigating in space and intra-corporeal suturing respectively). The 4K HD was significantly faster than 2D HD only in navigating in space task (p = 0.002). The error score between 3D HD and 4K HD were comparable in all tasks. The 2D HD had significantly more error scores compared to 4K HD, 3D HD in peg transfer task (p = 0.005, 0.014, respectively). 3D HD had significantly less workload than 2D HD and 4K HD in most of the dimensions of Surg-TLX CONCLUSIONS: 3D HD endovision system in comparison to 2D HD and 4K HD, may lead to faster execution without compromising safety of a task and is associated with less workload.

Predicting Outcomes After Blunt Chest Trauma-Utility of Thoracic Trauma Severity Score, Cytokines (IL-1ß, IL-6, IL-8, IL-10, and TNF-α), and Biomarkers (vWF and CC-16).

Thoracic trauma severity score (TTSS) has been used to assess severity and risk of pulmonary complications in patients with chest trauma. The role of cytokines and biomarkers in patients with chest trauma and its association with TTSS is not well elucidated. The aim of the study was to assess the cytokines (IL-1ß, IL-6, IL-8, IL-10, and TNF-α) and biomarkers (vWF, CC-16) in patients of thoracic trauma and correlate it with TTSS and patient's outcome. This was a prospective observational study. Serum and bronchoalveolar lavage fluid samples were collected from chest trauma patients. TTSS was calculated in all patients. Suitable controls for serum and bronchoalveolar lavage (BAL) sample were selected. The outcome parameters included patient discharge or death, duration of hospital, and intensive care unit (ICU) stay. Forty-three patients were included. There was no significant correlation between the measured cytokines and biomarkers and TTSS. The mean TTSS of patients who had a fatal outcome was significantly higher than the patients who recovered. Patients with a high TTSS score had a significant prolonged ICU stay. Patients with a prolonged hospital stay had lower values of CC-16. TTSS is a useful tool to predict severity of chest trauma and prolonged ICU stay. Lower levels of CC-16 in BAL fluid of chest trauma patients were associated with prolonged hospital stay suggestive of its protective role in the airway. Longer prospective studies are required to determine the role of cytokines and biomarkers in patients with thoracic trauma in predicting the patient's outcome.

Effect of structured training in improving the ergonomic stress in laparoscopic surgery among general surgery residents.

BACKGROUND: Minimal access surgery has fast become the standard of care for many operative procedures, but is associated with lot of ergonomic stress to the surgeons performing these procedures, which may result in reduction in surgeon's performance and work capacity. In this study, we evaluated the impact of structured training program in improving the ergonomic stress in trainee laparoscopic surgeons. METHODS: Laparoscopic surgeons were divided in 2 groups: trainee surgeons (ten) and expert surgeons (three). Baseline surface electromyography (sEMG) data were collected from bilateral deltoid, biceps brachii, forearm extensors, and pronator teres during a predefined suturing task on Tuebingen trainer with integrated porcine organs in both the groups. Trainee surgeons underwent 20 h of laparoscopic intra-corporeal suturing training and surface electromyography data were recorded at the end of training again and compared with baseline. RESULTS: Experts were found to have lower muscle activation (p < 0.05) and muscle work (p < 0.05) and better bimanual dexterity than the trainee surgeons at baseline. After training, the trainee surgeons showed significant improvement (p = 0.01), but still did not reach the values of the expert surgeons (p = 0.01). Right deltoid and pronator teres muscles were found to have maximal activity while performing intra-corporeal suturing. CONCLUSION: Structured and focused training outside operation theater can significantly reduce unnecessary muscle activation of trainee laparoscopic surgeons and better dexterity leading on to lesser ergonomic stress and thus possibly may reduce the risk of development of future musculo-skeletal disorders.

Solitary pelvic primary intraperitoneal hydatid managed with a minimal access approach: A case report.

Solitary primary pelvic intraperitoneal hydatid cysts are rare. We report the case of a 22-year-old women who presented with a dull ache in her lower abdomen for 2 years and increased urinary frequency over 3 months. Ultrasonography and CT indicated a solitary primary peritoneal pelvic hydatid cyst. Hydatid serology was positive. Perioperative albendazole was prescribed and laparoscopic cystectomy planned. Intraoperatively, dense adhesions to the omentum, urinary bladder, and left fallopian tube were taken down laparoscopically. A small Pfannenstiel incision was made to separate the bladder's left lateral edge and deliver the cyst externally. This report details our experience of managing this case and reviews pertinent literature.

Coronavirus disease 2019 and laparoscopic surgery in resource-limited settings.

INTRODUCTION: During the coronavirus disease 2019 (COVID-19) pandemic, the use of laparoscopy has been discouraged by the Intercollegiate General Surgery because of its potential for aerosol generation and infection. In contrast, the Society of American Gastrointestinal and Endoscopic Surgeons and the European Association of Endoscopic Surgery recommend continuing to use laparoscopy but with devices to filter released CO2 aerosol particles. However, commercially available systems are costly and may not be readily available. Herein, we describe a custom-made system to safely remove surgical smoke and CO2 , as well as a case of laparoscopic cholecystectomy in which we used it. MATERIALS AND SURGICAL TECHNIQUE: The patient had had multiple episodes of biliary pancreatitis and required urgent cholecystectomy during the COVID-19 pandemic. Although India was in complete lockdown, it was decided to operate with precaution. A system was designed using underwater seal chest tube drainage and an electrostatic membrane filter with a viral retention function greater than 99.99%. The system was connected to an extra port for continuous controlled egression of CO2 pneumoperitoneum. A regular four-port cholecystectomy was performed at an intra-abdominal pressure of 12 mm Hg. The gas flow rate was 10 L/min. CO2 for pneumoperitoneum, surgical aerosol, and effluents passed through the system before collecting in the suction apparatus. The exchange of operating instruments through the ports was kept to a minimum. It was done after the abdomen was temporarily desufflated using this system. DISCUSSION: The system we designed appears safe and is cost-effective. In resource-limited settings, it will be handy in patients requiring laparoscopic surgery both during and after the COVID-19 pandemic.

Persistent scrotal swelling after laparoscopic inguinal hernia repair: "Omentaloma of the scrotum".

Complete removal of all the contents of a hernial sac is crucial in laparoscopic inguinal hernia repair. We report a case who underwent transabdominal preperitoneal repair for a complete, irreducible inguinal hernia. He had persistent scrotal swelling and new onset scrotal pain post-surgery. Ultrasonography of the scrotum revealed a well-defined hypoechoic scrotal lesion. A magnetic resonance imaging revealed a fat-containing mass lesion, hypointense on T2 fat-saturated image. He underwent exploration of the scrotum and a well-encapsulated mass was excised. The histopathological evaluation revealed a well-encapsulated structure comprising of lobules of fibroadipose tissue with foci of chronic inflammation and foamy histiocytes likely retained omentum from previous surgery. His scrotal pain disappeared post-excision. A missed retained omentum in the hernial sac causes considerable anxiety to patients and diagnostic and therapeutic dilemmas for the treating surgeon. We coined the term "omentaloma of the scrotum" for such a lesion.

Emergency Surgery during COVID-19: Lessons Learned.

Introduction The ongoing coronavirus disease-2019 (COVID-19) pandemic has disrupted health services throughout the world. It has brought in several new challenges to deal with surgical emergencies. Herein, we report two suspected cases of COVID-19 that were operated during this "lockdown" period and highlight the protocols we followed and lessons we learned from this situation. Result Two patients from "red zones" for COVID-19 pandemic presented with acute abdomen, one a 64-year male, who presented with perforation peritonitis and another, a 57-year male with acute intestinal obstruction due to sigmoid volvulus. They also had associated COVID-19 symptoms. COVID-19 test could not be done at the time of their presentation to the hospital. Patients underwent emergency exploratory laparotomy assuming them to be positive for the infection. Surgical team was donned with full coverall personal protective equipment. Sudden and uncontrolled egression intraperitoneal free gas was avoided, Echelon flex 60 staplers were used to resect the volvulus without allowing the gas from the volvulus to escape; mesocolon was divided using vascular reload of the stapler, no electrosurgical devices were used to avoid the aerosolization of viral particles. Colostomy was done in both the patients. Both the patients turned out to be negative for COVID-19 subsequently and discharged from hospital in stable condition. Conclusion Surgeons need to adapt to safely execute emergency surgical procedures during this period of COVID-19 pandemic. Preparedness is of paramount importance. Full precautionary measures should be taken when dealing with any suspected case.
