An Analysis of the Impact of Intra-abdominal Pressure on Surgical Outcomes in Cases of Intestinal Obstruction: A Prospective Observational Study.

BACKGROUND: The decision and timing of surgical exploration of intestinal obstruction depend on the clinical findings and probable etiology of the symptoms. Patients with intestinal obstruction often have intra-abdominal hypertension (IAH), which is associated with a poor prognosis. PURPOSE OF THE STUDY: The purpose of the study is to evaluate the surgical outcomes in patients with intestinal obstruction in relation to intra-abdominal pressure (IAP). MATERIALS AND METHODS: The study was conducted on 50 patients with intestinal obstruction undergoing surgery. Preoperatively, IAP was measured in all the patients and was allocated into two groups based on the presence or absence of IAP. Patients were assessed for the postoperative length of hospital or ICU stay, surgical site infection, wound dehiscence, and recovery following surgery. RESULTS: The patients with preoperative IAH had significantly longer postoperative stays, with a median stay of eight days in these patients compared to four days in patients without IAH (p=0.009). A significantly higher number of patients (24%) had gangrenous changes on the bowel wall (p=0.042) and fascial dehiscence (p=0.018) in the group associated with raised IAP. A total of 75% of patients who required ventilator support belonged to the raised IAP group. The mean IAP in patients admitted to the ICU was significantly higher than in patients not admitted to the ICU (p=0.027). CONCLUSION: Preoperative IAH in intestinal obstruction is a significant factor in predicting the possibility of bowel ischemia with gangrene, perforation, intra-abdominal sepsis, surgical site infections, and prolonged hospital stay. Early surgical exploration and abdominal decompression must be considered in such cases.

Gallbladder perforation: Diagnostic accuracy of new CT difficulty score in predicting complicated laparoscopic cholecystectomy.

PURPOSE: To formulate and evaluate the diagnostic performance and utility of a new CT difficulty score in predicting difficult laparoscopic surgery in cases of gallbladder (GB) perforation. METHODS: This prospective single centre study included a total of 48 diagnosed cases of GB perforation on CT between December 2021 and June 2023, out of which 24 patients were operated. A new 6-point CT difficulty scoring system was devised to predict difficult laparoscopic approach, based on patterns of inflammation around the perforated GB that were found to be surgically relevant. The pre-operative imaging findings on CT were studied in detail and correlation coefficients of various imaging findings were calculated to predict difficult surgery. RESULTS: On CECT, the type of perforation, according to the revised Niemeier's classification could be exactly delineated in all 48 patients. A CT difficulty score of ≥ 3 was found to a good predictor difficult laparoscopic approach, with statistical significance (p = 0.001), sensitivity of 94.44%, specificity of 83.33%, PPV of 94.44% and NPV of 83.33%. Inflammatory changes around duodenum showed maximum correlation coefficient of 0.744 (p = 0.0001), around colon showed a correlation coefficient of 0.657 (p = 0.0005), and in the omentum had a correlation coefficient of 0.5 (p = 0.013)). Inter-observer agreement was also calculated for various findings and it was found to have moderate to strong agreement (κ value 0.5-1.0). CONCLUSION: The CT difficulty scoring system can be an effective tool in predicting difficult laparoscopic surgery in cases of GB perforation in an emergency setting which can help in decision making and improved patient outcome.

Current Trends in the Management of Port-Site Infections: A Case Series and a Review of Published Work.

Introduction Laparoscopic techniques have become standard for many surgeries, offering benefits such as quicker recovery and less pain. However, port-site infections (PSIs) can occur and pose challenges. PSIs can be early (within seven days) or delayed (after three to four weeks), with delayed PSIs often caused by non-tuberculous mycobacteria (NTMs). NTMs are difficult to treat and do not respond well to antibiotics, leading to prolonged and recurrent infections. Guidelines for PSI management are limited. This summary highlights a case series of 10 patients with PSIs, discussing their treatment experience and presenting a treatment algorithm used at our institute. Methods This is a retrospective study (2015-2020) on chronic port-site infections (PSIs) in laparoscopic surgeries. Data were collected on patient demographics, surgery type, prior treatment, and management at the institute. Results The study analyzed 10 patients with chronic PSIs following laparoscopic surgery between 2015 and 2020. Laparoscopic cholecystectomy was the most frequent index surgery. Three patients had a history of treatment with varying durations of anti-tubercular therapy, one of whom had completed anti-tubercular treatment prior to presentation. Complete surgical excision with histopathological examination and fungal, bacterial and mycobacterial cultures were performed. Seven of the 10 patients were treated with oral ciprofloxacin and clarithromycin combination therapy for three months, two were treated with culture-based antibiotics and one was treated with anti-tubercular therapy. All patients improved on treatment. The mean follow-up period was 52 ± 9.65 months, with no relapses being reported.  Conclusion Port-site infections (PSIs) are troublesome complications of laparoscopic surgery that can erode the benefits of the procedure. Delayed PSIs caused by drug-resistant mycobacteria are difficult to treat. Improved sterilization methods and thorough microbiological work-up are crucial. Radical excision and prolonged oral antibiotics are effective treatments. Clinicians should avoid empirical antibiotic therapy to prevent antimicrobial resistance.

Comparison of GATA-3, Mammaglobin and GCDFP-15 Expression in Primary, Metastatic and Triple Negative Breast Carcinomas: An Indian Scenario.

BACKGROUND AND OBJECTIVE: Mammaglobin and GCDFP-15 are traditional immunohistochemistry (IHC) markers utilized to recognize metastasis of breast carcinoma in an unknown primary. GATA-3 is increasingly being used as a marker of primary breast origin. This study was done to evaluate and compare GATA-3 with GCDFP-15 and Mammaglobin in invasive primary including metastatic and triple negative breast carcinomas. METHODS: Immunohistochemistry for GATA-3, GCDFP-15 and Mammaglobin was applied on 100 cases of primary breast carcinomas, including 20 triple negative cases and 30 cases of metastatic breast carcinomas. Staining scores were given for each marker by multiplying the percentage of positive tumor cells by the intensity of staining (1+, 2+ or 3+), with scores ranging from 0 to 300. Staining score of 1 or more was considered positive. RESULTS: GATA-3 was expressed in 92% of primary, 80% of metastatic and 60% of triple negative breast carcinomas, with an average staining score of 270. Mammaglobin was expressed in 68% of primary, 56.6% of metastatic and 25% of triple negative breast carcinomas, with an average staining score of 180. GCDFP-15 was expressed in 48% of primary, 26.6% of metastatic and 05% of breast carcinomas, with an average staining score of 60. GATA-3 demonstrated to have higher staining score (average of 270) than other two markers in maximum number of cases. CONCLUSION: GATA-3 has a higher sensitivity and increased staining scores in primary breast carcinomas, metastatic breast carcinomas as well as in triple negative breast carcinomas.

Crosstalk Between Programmed Death Ligand 1, Ki-67 Labelling Index, and Tumor-Infiltrating Lymphocytes in Invasive Breast Cancer and Clinicopathological Correlations in a Tertiary Care Center in Western India.

Background & Objective: Breast cancer is the leading cancer among Indian women and accounts for about 25% of all cancer cases worldwide. The present study aimed to assess Programmed Death Ligand-1 (PD-L1) expression in tumoral cells and tumor-infiltrating lymphocytes (TILs) and evaluate their correlations with the Ki-67 labelling index in invasive breast carcinomas (IBC). Methods: This descriptive observational study was conducted during 2016-2018 and included all diagnosed cases of IBC. The relationships between PD-L1 expression, TILs, hormone receptors, Ki-67, and clinicopathological parameters were studied in IBC. Statistical analysis was performed by SPSS version 23. Results: Out of 114 evaluated cases, 33.33% (N=38) showed PD-L1+ expression in tumor cells and 47.37% (N=54) had PD-L1+ expression in TILs. A high Ki-67 index was observed in 96 cases. Moreover, 49 patients were estrogen receptor (ER)- and 65 were ER+. We observed that 22 of 49 ER- and 49 of 65 ER+ subjects showed PD-L1+ expression, respectively. Conclusion: Our results showed a significant relationship between PD-L1 expression in tumoral cells and TILs, as well as between Ki-67 and TILs. In addition, an inverse correlation was noted between PD-L1 expression and ER. The PD-L1 expression in tumors and TILs and correlation with high Ki-67 may prove the importance of PD-L1 in targeted chemotherapy. An inverse relationship between PD-L1 and ER expression in tumoral cells suggests scope for immunotherapy in ER- IBC. However, further research with more cases is required.

Pain After Transabdominal Preperitoneal (TAPP) or Totally Extraperitoneal (TEP) Technique for Unilateral Inguinal Hernia: A Randomized Controlled Trial.

Introduction Laparoscopic inguinal hernia repair is the most commonly performed surgery in many hospitals. This study aimed to compare the outcome of the transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) techniques in unilateral, uncomplicated inguinal Hernia. Material and methods This prospective randomized study was conducted in a tertiary care hospital in North India from November 2018 to March 2020. Sixty-eight male patients of unilateral, uncomplicated inguinal hernia were enrolled for laparoscopic hernia repair. The first group of 34 patients underwent TAPP repair and the second group of 34 patients underwent TEP repair under general anesthesia (GA). Both groups were compared for intraoperative or postoperative complications, analgesic requirements, postoperative pain, length of hospital stay, resumption of routine activity, and patient satisfaction scores. Fisher's exact test or Chi-square test were used for nominal data and the median or interquartile range was used for ordinal data. Results The mean operative time for TAPP was more than that for the TEP group (101 vs 76, p<0.001). The TAPP group exhibited significantly less postoperative pain at six hours, 24 hours and seven days than TEP (p<0.001) and an insignificant difference at three months of the follow-up period (p=0.188). Additional analgesics requirement was less in the TAPP group, although the difference was not significant (p=0.099). Seroma formation was found in four patients (11.8%) in the TEP group and two patients (5.9%) in the TAPP group (p= 0.672). Length of postoperative hospital stay (p=0.907), resumption of routine activity (p=0.732), and patient satisfaction scores (p=0.492) during follow-up were similar in both groups and were also insignificant. Conclusion The TAPP technique is slightly better than TEP for inguinal hernia in terms of lesser postoperative pain with similar chances of complications and other outcomes.

Cytopathologic findings in histiocytic sarcoma of thyroid mimicking as anaplastic carcinoma: A report of a rare case with review of literature.

BACKGROUND: Histiocytic sarcoma is an extremely rare malignant hematological histiocytic neoplasm which is a diagnosis of exclusion based on its morphological and predominantly immunohistochemical criteria. CASE DESCRIPTION AND DIAGNOSIS: A 63-year female presented with complaints of a midline neck swelling along with right sided neck swelling. On fine-needle aspiration (FNA) from the thyroid lesion and the right cervical lymph node, the smears showed similar findings and a provisional morphological diagnosis of malignant spindle cell neoplasm was kept. On immunohistochemistry, the tumor cells showed immunoreactivity for vimentin, CD45, CD 68 and fascin and were immunonegative for thyroglobulin, S100, CD21, CD3, CD4 and other markers. Based on the immunohistochemical profile, a diagnosis of histiocytic sarcoma was established. CONCLUSION: Histiocytic sarcoma is a rare malignant neoplasm that can be easily missed in thyroid resembling an anaplastic carcinoma.

Does laparoscopic hernia repair affect the vascularity of testis?

CONTEXT: Laparoscopic hernia repair, despite its safety and effectivity is related to some drawbacks. Testicular complications are uncommon but serious among them. Testicular atrophy occurs in 0% to 2% of patients after hernioplasty. AIM: In this study, we tried to evaluate the effects of laparoscopic total extraperitoneal (TEP) repair on testicular blood flow in Indian population by comparing the testicular perfusion in preoperative and postoperative status. SETTINGS AND DESIGN: A prospective study. SUBJECTS AND METHODS: A prospective study was conducted among adult male patients having an uncomplicated inguinal hernia. Preoperative and postoperative CDUS evaluation of testicular blood flow was done for each patient. STATISTICAL ANALYSIS USED: Data were analyzed using the SPSS (SPSS, Chicago, IL, USA) software program. RESULTS: The resistive indexes of testicular, capsular, and intratesticular arteries of the operated and nonoperated side were similar preoperatively and did not differ ominously postoperatively. CONCLUSION: Laparoscopic hernia surgery does not have any significant effect on testicular blood supply and can be advocated safely without any added risk of testicular atrophy.

Gargantuan primary scrotal calcinosis - Surgical, cosmetic, and sociopsychiatric concern.

A 47-year-old healthy male had a scrotal lesion for about 10 years which was gradually increasing in size and not associated with pain or tenderness. It was dwarfing the penis and attained its present size of 14 cm × 7.5 cm × 6 cm. There were no discharging sinuses, tenderness, or ulceration. He had no significant past or family history. Laboratory examination revealed unremarkable serum calcium, serum phosphate, serum total protein, serum uric acid, and serum parathormone levels. A clinical diagnosis of epidermal inclusion cysts was suggested. The lesion was entirely excised and sent for histopathologic examination.

Kimura's disease revisited: report of a case with a clinical and cytohistological correlation.

Kimura's disease (KD) is a rare chronic inflammatory disorder of unknown aetiology. The common mode of clinical presentation is in the form of painless subcutaneous nodules usually seen in the head and neck region and is associated with regional lymphadenopathy and occasional involvement of the major salivary glands. It is often accompanied by peripheral eosinophilia and markedly elevated serum IgE levels. Histologically, it is characterised by reactive lymphoid follicles with eosinophilic infiltration, sometimes forming eosinophilic abscesses and prominent postcapillary venules. There is no consensus about optimal treatment of this disease in the reported literature. This condition seldom resolves spontaneously but the prognosis is good. Malignant transformation has not been reported. Early diagnosis of KD could spare the patient unnecessary and potentially harmful diagnostic procedures. A high index of clinical suspicion can help in diagnosing this disease and aid in better management.

Primary mediastinal chondrosarcoma with Horner's syndrome.

Chondrosarcomas are uncommon tumors of the mediastinum. Cases reported in the literature are chondrosarcomas originating from osteocartilaginous structures; primary chondrosarcomas that have no anatomical relation with cartilaginous structures are rare. They present with myriad symptoms depending on compression of the adjacent structures; but Horner's syndrome, as a symptom, has not been described before. We report a rare case of a large primary mediastinal chondrosarcoma that presented with Horner's syndrome.
