RESUMO
Pulmonary mucormycosis is a rare, life-threatening fungal infection usually seen in immunocompromised patients. Mortality in such patients is high due to underlying immunosuppression and poor general condition of the patients. Invasion of the adjacent structures is known but, to the best of our knowledge, pulmonary mucormycosis presenting with a full thickness chest wall erosion has not been reported. We report such a case with chest wall destruction with superadded bacterial infection. The use of prosthetic materials for chest wall reconstruction was not possible due to the presence of infection. In addition, there were other intra-operative and post-operative challenges which we managed using a multidisciplinary approach. This report highlights the successful outcome of this complex situation using pre-operative optimisation, adequate surgical debridement and effective management of post-operative complications with patience and perseverance.

Objective: This study was conducted to evaluate the frequency and clinicopathologic correlates of human epidermal growth factor receptor 2 (HER-2)/neu and betacatenin (BC) oncoproteins in gastric adenocarcinoma and to seek correlation if any between their expression status. Materials and Methods: This cross-sectional analytical immunohistochemistry (IHC) study was performed on 50 cases of gastric adenocarcinoma. HER-2/neu immunoexpression was scored as per criteria by Ruschoff et al. as positive (3+), equivocal (2+), and negative (1+, 0). Aberrant BC expression was categorized as nuclear, cytoplasmic, and reduced membranous immunoexpression. Protein expression results of both oncoproteins were correlated with conventional clinicopathological parameters. Correlation between immunoexpression profiles of both proteins was also analyzed. P <0.05 was considered statistically significant. Results: HER-2/neu positivity (2 + and 3+) was seen in 94% of the cases; almost 60% had strong (3+) expression. All cases showed aberrant BC immunoexpression (any pattern) except 2 cases that revealed negative expression (a form of aberrant immunoexpression) and were removed from analysis due to a very small number. The pattern of BC expression was as follows: nuclear expression (38%), cytoplasmic expression (82%), reduced membranous expression (96%), no staining (4%) cases. HER-2/neu expression correlated with age. No significant correlation was found between any of the 2 oncoprotein immunoexpression and other clinicopathological parameters (P > 0.05). Concordance between protein expression of HER-2/neu and BC was seen in >93% cases, however, the correlation was not significant. Conclusion: HER-2/neu and BC oncoprotein expression are frequently dysregulated in gastric adenocarcinomas. The significance of pathways involving HER-2/neu and BC in gastric carcinogenesis should be explored.

Background The Covid-19 pandemic severely affected surgical training as the number of surgeries being done was reduced to a bare minimum. Teaching and training of clinical skills on a simulator are desirable as they may have an even larger role during the Covid-19 pandemic. Commercially available simulators with optimum fidelity are costly and may be difficult to sustain because of their recurring cost. The development of low-cost simulators with optimum fidelity is the need of the hour. Methods We developed animal tissue-based simulators for imparting skills training to surgical residents on some basic and advanced general surgical procedures. Porcine tissue and locally available materials were used to prepare these models. The models were pilot-tested. Standard operating procedures were developed for each skill that was shared with the participants well before the 'hands-on' exercise. An online pre-test was conducted. The training was then imparted on these models under faculty guidance adhering to Covid-19-appropriate behaviour. This was followed by a post-test and participant feedback. The entire exercise was paperless. Results Sixty residents were trained in 10 sessions. Most of the participants were men (44; 73%). The mean pre-test and post-test scores were 40.92 (standard deviation [SD] 6.27) and 42.67, respectively (SD 4.06). Paired sample t-test suggested a significant improvement in the post-test score (p<0.001). The activity and the models were well appreciated by the residents. Conclusion The animal tissue-based indigenous models are easy to prepare, cost-effective and provide optimum fidelity for skill training of surgical residents. In addition to skill acquisition, training on such modules may alleviate the stress and anxiety of the residents associated with the loss of surgical training during a time-bound residency period.

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.

BACKGROUND: Despite the acceptance of non-operative management (NOM), there is no consensus on the optimal length of hospital stay in patients with blunt liver and splenic injury (BLSI). Recent studies on pediatric patients have demonstrated the safety of early discharge following NOM for BLSI. We aimed at evaluating the feasibility and safety of early discharge in adult patients with BLSI following NOM in a randomized controlled trial. MATERIALS AND METHODS: After initial assessment and management, patients aged 18-60 years with BLSI planned for NOM were randomized into 2 groups: Group A (test group; discharge day 3), and Group B (control group; discharge day 5). Standard NOM protocol was followed. These patients were discharged on the proposed day if they met the pre-defined discharge criteria. All patients were followed at days 7, 15, and 30 of discharge. RESULTS: Sixty patients were recruited, 30 randomized to each arm. Most patients were males and aged less than 30 years. Road traffic injury was the most common mode of injury. Both groups were comparable in demography and injury-related parameters. 27 patients (90%) from group A and 28 patients (93%) from group B were discharged on the proposed day. Three patients had unplanned hospital visits for reasons unrelated to BLSI. All patients were asymptomatic and had a normal examination during their scheduled follow-up visits. CONCLUSION: Adult patients undergoing NOM for BLSI can be safely discharged after 48 h of in-hospital observation, provided other injuries precluding discharge do not exist.

OBJECTIVE: We present our experience of pediatric injuries over 5 years from a level I trauma centre. METHODS: De-identified data from a prospectively maintained database of pediatric patients was analyzed for demography and injury-related parameters, and management provided. RESULTS: There were 906 patients (698 male, median age 12 years). Predominant cause was road traffic injuries. The median injury severity score was 9. Abdomen and thorax were the commonest regions affected. There were 44 deaths. Sepsis and hemorrhage were the commonest causes of mortality. CONCLUSIONS: The magnitude of pediatric injuries is significant, and maintenance of dedicated trauma registries is the need of the hour.

Thoracoplasty is a procedure to collapse the chest wall over a residual space in the thoracic cavity in order to abolish and avoid the complications associated with this dead space. Although effective in achieving this, the procedure is crippled by poor cosmetic appearance and functional outcome. We report a case of recalcitrant complex chest wall defect with a large cavity, marred by visible heart and poor availability of local muscles, that was successfully managed by a novel technique of thoracoplasty with acceptable postoperative appearance and function.

Major vascular injury during surgery is life threatening and can be a nightmare for any surgeon.We share our experience of a 42-year-old woman where right common iliac artery and both common iliac veins were accidentally injured during lumbar discectomy leading to haemorrhagic shock. Patient was resuscitated and explored. A 4 cm segment of right common iliac artery was found lacerated along with perforations of both iliac veins. Proximal segment of internal iliac artery was mobilised quickly and vascular continuity was restored by end-to-end anastomosis of this segment to the proximal segment of common iliac artery after excising the damaged segment. Iliac veins were repaired primarily. Patient made an uneventful recovery. We share this technique as it was found expeditious and effective and may benefit surgeons working in this field.

CECT scan is considered essential for selective non-operative management (SNOM) of patients with abdominal trauma. However, CECT has its own hazards and limitations. We evaluated the safety and efficacy of selective non-operative management of patients with abdominal trauma without the mandatory use of CECT scan in a prospective study. Patients with peritonitis and ongoing intra-abdominal bleed were excluded. Consenting FAST positive, hemodynamically stable patients with blunt and penetrating abdominal trauma between 18 and 60 years of age were included and admitted for SNOM and detailed ultrasonography of the abdomen (in all) with or without CECT abdomen (selectively). Eighty-four patients with abdominal trauma were admitted during the study period. Twenty-two patients did not satisfy the inclusion criteria and 18 required immediate laparotomy based on primary survey. Remaining 44 patients were admitted for SNOM: mean ± SD age of these patients was 27 ± 8.7 years; 40 (89 %) were males. Thirty-five patients (79.54 %) sustained blunt trauma (RTI = 16, Fall = 16, others = 3) while nine patients (20.45 %) sustained penetrating trauma. SNOM without CECT was successful in 36 (81.82 %) patients. Five (11.36 %) patients underwent delayed emergency laparotomy based on clinical and detailed USG evaluation. CECT was not done in these patients. Three patients underwent CECT for various reasons; however, they were managed with SNOM. Thus, SNOM without abdominal CECT was successful in 36 (81.82 %) patients. SNOM failed in five patients but abdominal USG was sufficient. SNOM can be practised safely in patients of abdominal trauma with limited use of CECT scan.
RESUMO
To study the effect of primary and delayed primary closure of skin incision on wound outcome in patients with non-traumatic ileal perforation, 68 patients of ileal perforation were studied in a prospective randomized clinical trial. Patients fulfilling inclusion criteria were divided into ileostomy and non-ileostomy groups, both of which were then randomized into two subgroups each depending on whether skin was closed primarily or in a delayed primary manner. Wound infection and dehiscence were the main outcome parameters studied. The data collected was analyzed using appropriate statistical tools taking significant p value at 5 %. Most patients were 21-30 years of age. Male:female ratio was 3.2:1. The overall incidence of wound infection was 63 %. Wound infection was strongly associated with the incidence of superficial wound dehiscence and total wound dehiscence that were 11.76 and 47 %, respectively. Mortality was 10.3 %. Methodology of wound closure has no significant impact on incidence of wound infection, wound dehiscence, and mortality, although the onset of wound complications is significantly delayed with delayed primary closure of the skin.
RESUMO
The management of hemodynamically normal patients with retained intra-pericardial foreign body remains a matter of conjecture. The available literature supports non-operative management of such innocuous foreign bodies. We report our experience of a hemodynamically normal patient with a retained intra-pericardial pellet from a firearm injury. He initially received successful non-operative management but developed fatal hemopericardium 21 days after injury. In this paper, we discussed the pitfalls in the management of such injuries in light of the available literature and summarized the clinical experience.

BACKGROUND: Penetrating injuries of the perineum are rare but very dangerous. Since the genitourinary and colorectal organs may be injured, how to evaluate surgical management of the injury is very important. METHODS: The present report presents a case of penetrating injury of the perineum by a wooden stick when the patient fell on the upright wooden stick from a tree. The three feet long stick entered the perineal region just left lateral to the anal opening. Upon reaching the thoracic cavity, it broke and only a foot stick was left in the subcutaneous plane. These injuries are potentially serious with risk of damage to multiple organs. Exploratory laprotomy was done, and bladder injury was repaired. The entry wound and the track of stick was thoroughly washed and allowed for secondary intention healing. RESULTS: The post operative period was uneventful and the patient recovered fully. CONCLUSION: Meticulous evaluation and surgical management of perineal injuries are the key to prevent devastating complications.
RESUMO
Assessment using portfolios has recently gained wider acceptance, and is being considered relevant to several educational aspects in medicine, including formative and summative assessment during resident training, revalidation and continuing professional development. In this article, we provide an overview of the use of portfolio as an assessment and learning tool. We have discussed the rationale of using portfolio in medical education, its advantages and criticisms, and some of the associated challenges and dilemmas.

The anatomical description of the area requiring dissection during cholecystectomy is incomplete and incorrect. We carefully observed the anatomy of this region for over 20 years in various biliary pathologies and present our view. Describing this area in the form of triangles is incorrect. There exists a definite plane between the two folds of peritoneum in this region, wherein the cystic duct and the cystic artery traverse. The description of the "triangles" that require dissection during cholecystectomy are not strictly geometrical triangles; hence, the area bounded by these so-called triangles should be renamed as "Calot's region." The surgeons should take advantage of the existence of a definite "ducto-arterial plane" in the Calot's region and dissect it sharply to avoid ductal and vascular injuries.
RESUMO
Negative appendectomy remains a concern in current surgical practice. Data from the developing world is scarce. Data of appendectomies during the last 5 years were analyzed. Interval and incidental appendectomies were excluded. The demographic details, presenting complaints, clinical signs, and investigations performed were recorded in a predesigned proforma. The data were critically analyzed. Six hundred eighty-five appendectomies were performed during the period. One hundred eighty-five patients with a normal appendix were identified on histopathology. Sixty-seven patients with incidental or interval appendectomies were excluded. Thus, 118 patients had appendectomies performed erroneously. All these patients with presumed diagnosis of acute appendicitis were operated on by resident surgeons. Records of 17 patients could not be retrieved. The most common symptom was abdominal pain (100 %), and the commonest sign was right iliac fossa tenderness (93 %). Most of the patients underwent USG to supplement the diagnosis. CT scan and diagnostic laparoscopy were not performed. The negative appendectomy rate was 17.2 % (12.4 % in males; 33.3 % in females). The highest incidence of negative appendectomy was in females aged 11-20 years (66.7 %). The rate of negative appendectomy at our institute is comparable with the world statistics. More diligence is required in making the clinical diagnosis of acute appendicitis, especially in young females. The use of C-reactive protein and CT scan may decrease the negative appendectomy rate.
RESUMO
BACKGROUND: Lately, Focused Assessment with Sonography in Trauma (FAST) is preferred over diagnostic peritoneal lavage (DPL) as adjunct to primary survey. However, this is not evidence-based as there has been no randomized trial. METHODS: In this study, 200 consecutive torso trauma patients meeting inclusion criteria were randomized to undergo either DPL or FAST. The results were then compared with either contrast enhanced computerized tomography (CECT) (in patients managed non-operatively) or laparotomy findings (in patients undergoing operative treatment). Outcome parameters were: result of the test, therapeutic usefulness, role in diagnosing bowel injury and time taken to perform the procedure. RESULTS: Two hundred patients with a mean age of 28.3 years were studied, 98 in FAST and 102 in DPL group. 104 sustained blunt trauma and 76 sustained penetrating trauma due to stabbing. In addition, 38 (38.7%) were FAST positive and 48 (47%) were DPL positive (p=0.237, not significant). As a guide to therapeutically beneficial laparotomy, negative DPL was better than negative FAST. For non-operative decisions, positive FAST was significantly better than positive DPL. DPL was significantly better than FAST in detecting as well as not missing the bowel injuries. DPL took significantly more time than FAST to perform. CONCLUSION: This study shows that DPL is better than FAST.
