Sentinel Lymph Node Biopsy after Neoadjuvant Chemotherapy in Breast Cancer Patients with Positive Nodes Using Low-Cost Dual Dye Technique: Identifying Factors Associated with Adequate False Negative Rate Threshold.

Background: In this study, we evaluated the feasibility of the sentinel lymph node (SLN) identification rate (SLN-IR) of fluorescein-guided sentinel lymph node biopsy (SLNB) in combination with methylene blue dye (MBD) and factors which can lead to a false negative rate (FNR) threshold of 10%. Methods: This was a prospective cross-sectional non-randomized validation study in patients with post-neoadjuvant chemotherapy (NACT) clinically node negative axilla who were node positive prior to start of NACT. Patients underwent validation of SLNB using fluorescein (and blue LED light) and MBD. Axillary dissection was performed irrespective of SLNB histology. SLIN-IR and FNR were assessed and compared with various molecular subtypes. Results: The SLNs were identified in 102 out of 120 (85%) post-NACT patients. The median number of sentinel lymph nodes identified was 2 (range 1-3). The SLN-IR using MBD was 85%, FD was 82.5%, and combined MBD FD was 85%. Two or more SLNs were removed in 72 patients and 11 patients had tumor in the rest of the axilla, resulting in an FNR of 17.4%. An FNR was 25% in case only one SLN was found, and it was 11.42% if two or more than two SLNs were excised. Conclusions: This cohort study found that use of low-cost dual dyes in patients with positive axillary disease, rendered cN0 with NACT, with 2 or more negative SLNs with SLNB alone, results in an FNR of 11.4%. Her 2 positive and TNBC with 2 or more negative SLNs are associated with an FNR of <10%. However, the number of such patients was small and further studies with larger sample size are warranted to confirm these findings.

Defunctioning ileostomy for typhoid ileal perforations: Out of the frying pan into the fire?

Typhoid ileal perforation (TIP) is a common surgical emergency in low-middle income countries (LMICs). Its high surgical morbidity and mortality is due to its often late presentation or diagnosis, the patient's malnutrition, severe peritoneal contamination and unavailability of intensive care in most peripheral hospitals. This prompted the philosophy of minimizing the crisis by avoiding any repair or anastomosis, limiting the surgery in these physiologically compromised patients and performing only a temporary defunctioning ileostomy (DI) which could then be closed 10-12 weeks later.

Effect of chewing gum in reducing postoperative ileus after gastroduodenal perforation peritonitis surgery: A prospective randomised controlled trial.

Chewing gum reduces the duration of postoperative ileus and early recovery of bowel function following elective abdominal surgery. However, its role has not been studied in cases of gastroduodenal perforation peritonitis, prompting us to conduct this study. Patients were randomised into two groups, 39 patients received chewing gum (study group) and 43 patients were in the control group. Sensation of hunger, appearance of first bowel sound, and passages of flatus and faeces were significantly early in the study group; their hospital stay was also shorter. Chewing gum reduces the duration of postoperative ileus in cases of gastroduodenal perforation peritonitis.Registration number: IEC/2020-23/3359 dated 13 December 2020, Institutional Ethics Committee, Netaji Subhash Chandra Bose Medical College, Jabalpur, India.

Patient Perspectives After Surgery-Related Complications Among Breast Cancer Patients from a LMIC.

Long-term quality of life in breast cancer patients has been studied and published regularly. However, the lived experiences of patients who develop complications after surgery are not well understood. Determining this experience of patients is challenging in most low- and middle-income countries where the majority of patients belong to poor strata of society and are uneducated. We aimed to explore the thoughts, feelings, and experiences of patients with surgery-related complications after breast cancer surgery. Purposive sampling was used to identify patients who developed any postoperative complication, and semi-structured interviews were conducted. Common patterns of patient experiences were identified and analyzed using descriptive thematic analysis. Twenty-eight patients out of 210 developing complications postoperatively were identified. The median age was 48 years (range 32-65 years). The majority (n = 26) were housewives, educated below the primary level (n = 11) and below the poverty line (n = 13). Complications included seroma (n = 17), flap necrosis and infection (n = 5), and hematoma (n = 1). Seven domains emerged from the interviews-knowledge of complications, psychological impact, burden, disruptiveness, social impact, relationship with the surgical team, and suggestions to improve the experience. The themes identified in the present study provide insights into the lived experiences and can inform the future development of patient-reported outcome measures and quality improvement programs, including more effective pre-operative counseling and consent.

Access, Safety, and Barriers in Adoption of Emergency Laparoscopy Surgery for Trauma Patients in a Low-Resource Setting.

Introduction This study analyzes barriers to the adoption of emergency laparoscopy (EL), safety, and accessibility in a low-resource setting of a low- and middle-income country (LMIC). Methods In this prospective observational study, patients with blunt trauma abdomen (BTA) who required exploration were included and divided into two groups-open exploration (open surgery [OSx]) and laparoscopic exploration (laparoscopic surgery [LSx]). Data were compiled and analyzed. Results Out of 94 BTA patients, 66 required exploration, and the rest were managed conservatively. Out of 66 patients, 42 were in OSx and 24 were in LSx, reason for not selecting LSx was the surgeon's preference for OSx in 26 patients and the lack of availability of operation theater (OT) slots in 16 patients. LSx even after indication was less likely if patients had preoperative evidence of perforation peritonitis. Conclusion Lack of resources (OT availability and trained personnel) are barriers to the adoption of emergency LSx in low-resource settings.

Low-cost solutions incorporated in a standard surgical pathway for early breast cancer: A pilot study.

We present the results of incorporation of low-cost solutions to provide a standard surgical care for early breast cancer (EBC) patients. This surgical pathway consists of a low-cost vacuum-assisted core needle biopsy, sentinel lymph node biopsy (SLNB) using low-cost methylene blue and fluorescin dyes under local anesthesia and oncoplastic breast surgery. Patients assessed as clinically node-negative axilla underwent such treatment. SLNB using low-cost dyes was performed without any complication. Oncoplastic surgical techniques were opted for in 32 patients, and the lumps were all excised with a ∼1-cm all-around margin on the final histopathological examination. Standard breast cancer surgery can be provided in low-resource settings to eligible EBC patients with low-cost solutions.

Molecular Profile and Clinico-pathological Characteristics of Breast Cancer in Central India: First Investigative Report.

Stage at presentation and molecular profile are the two most important factors affecting breast cancer prognosis. This is the first study on molecular breast cancer subtypes from Central India. We prospectively reviewed 260 consecutive breast cancer patients diagnosed at the Department of Surgery, Government NSCB Medical College, Jabalpur (MP), between January 2017 and December 2020. Clinico-pathological and molecular profiles and their associations with the characteristics of the tumor were analyzed. The median age at diagnosis was 44.7 years (range 21-93). Eleven percent (n = 11) were in clinical stage I, 12.7% (n = 12) were in stage II, 56% (n = 146) in stage III, and 20% (n = 52) were in stage IV. Metastatic lymph node positivity rate was 85% at the time of diagnosis. Luminal subtype was present in 50% (n = 131), Her 2 neu-enriched type in 21.5% (n = 55), and triple-negative subtype in 28.5% (n = 74). A stronger association was observed for each increasing clinical stage for Her 2 neu-enriched and triple-negative breast cancer (TNBC) but not luminal-type tumors. For grade of tumors, patients with luminal subtype had a higher percentage of lower grades (p = .001); however, Her 2-enriched and TNBC had higher proportion of grade III tumors (for Her 2-enriched p = .04, TNBC p = .001). In Central India, like other regions of India, breast cancer occurs at an earlier age and is diagnosed at a more advanced stage. In this region, pre-menopausal breast cancer is more common than post-menopausal and TNBC tumors have similar incidence in pre-menopausal and postmenopausal women.

Validation sentinel lymph node biopsy study in cN0 axilla using low-cost dual dye technique: potential solution for resource poor settings.

BACKGROUND: Sentinel lymph node biopsy (SLNB) using radio-pharmaceutical and a blue dye is gold standard for axillary staging in clinically node-negative breast cancer. High costs and limited availability of radio-pharmaceutical and/or gamma probe are major deterrents in performing SLNB in developing countries. In this study, we evaluated feasibility of SLN identification (SLN-IR) of fluorescein-guided (FG) SLNB in combination with methylene blue dye (MBD). METHODS: This was a prospective cross-sectional non-randomized validation study in patients with clinically node-negative axilla. Patients underwent validation SLNB using fluorescein (and blue LED light) and MBD. Axillary dissection was performed irrespective of SLNB histology. SLIN-IR and False Negative Rate (FNR) were assessed for both groups. RESULTS: The SLNs were identified in 29 (96.6%) pre-chemotherapy patients and 23 (82%) post Neoadjuvant Chemotherapy (NACT) patients. The median number of sentinel lymph nodes identified was 3 (range of 1-5) in pre-chemotherapy patients and 1 (range of 1-3) in post NACT patients. The SLN-IR using MBD was 90%, FD was 86.7% and combined MBD FD was 96.7% in pre-chemotherapy patients. The SLN-IR using MBD was 82%, FD was 71% and combined MBD FD was 82% in in post NACT patients. The false negative rate (FNR) in pre-chemotherapy group was 8.0% (MBD), 8.3% (FD) and 7.4% (MBD + FD). The FNR in post NACT group was 8.7% (MBD), 10% (FD) and 8.7% (MBD + FD). CONCLUSION: This prospective validation study showed adequate SLN-IR and FNR using low-cost dual dyes in early breast cancer patients and can be used in low resource settings. However, SLNB in post NACT axilla though viable along with a satisfactory FNR, is associated with low identification rate and needs further evaluation.

A 10-Year Study of the Outcome of Wilms' Tumor in Central India and Identifying Practice Gaps.

Introduction: Despite remarkable improvement in Wilms' tumor (WT) survival in Western world, sub-optimal outcome in resource-constrained settings is influenced by late presentation, larger size, and poor access to treatment. This prompted us to study the outcome at a tertiary care center and to identify the global and local practice gaps. Materials and Methods: A retrospective, observational study of WT was conducted from October 2009 to September 2019 at a tertiary care setting. Following the National Wilms' Tumor Study Group protocol, an upfront nephrectomy (unilateral resectable tumors) and preoperative chemotherapy (large/unresectable Stage I-III) were followed. The records were reviewed for demographics, stage, preoperative chemotherapy, predictive factors, and outcome. Survival curves were plotted by the Kaplan-Meier method, and analysis was performed using the SPSS software version 16. Results: One hundred and fifty-six children were included, median age was 4.1 years, with a male predominance. The most common stages of the presentation were II (40.4%) and III (34.6%). An upfront surgery was done in 27.6%, while remaining received preoperative chemotherapy. The median follow-up was 22 months, and the events included relapse in 46 (29.48%) and death in 54 (34.61%). The mean survival time was 45.7 (95% confidence interval [CI], 41.08-50.30). The 2-year overall survival was 65.38% (95% CI, 59-73), and the 2-year event-free survival was 36% (95% CI, 32-41). On comparison of the impact of preoperative chemotherapy, the survival estimates in Stages I-III and relapse rate were statistically similar, tumor size reduced significantly, and tumor spill was significantly lower (P < 0.05). Conclusion: WT is associated with late presentation, sub-optimal survival, and higher relapse in our setting associated with practice gaps related to the management including practice violations.

A simple prognostic scoring system for typhoid ileal perforation peritonitis.

The increasing awareness of the worse than expected outcome after typhoid ileal perforation (TIP) prompted us to prospectively prognosticate patients with the help of the Jabalpur prognostic score (JPS), a simplified scoring system for peptic perforation peritonitis (PPP). Eighty-two consecutive patients with TIP were studied from May 2005 to August 2008 in the Department of Surgery, NSCB Government Medical College, Jabalpur (MP), India. Six parameters used in the JPS were recorded: age, heart rate, mean blood pressure, serum creatinine, any co-morbid illness and perforation-operation interval. JPS correlated with morbidity and mortality in TIP patients and, as the score increased, so did the morbidity and mortality. Survivors had a significantly lower mean score (3.86 ± 2.23) than non-survivors (7.94 ± 3.6; P < 0.001). Expectedly, TIP patients had worse outcome, stage by stage, than PPP patients. JPS can be easily modified for TIP (JPS-TIP) and can be easily used for its prognostication.

Effect of Candida infection on outcome in patients with perforation peritonitis.

Perforation peritonitis is treated with surgery and antibiotics. This study was conducted to identify bacterial and fungal microorganisms responsible for peritonitis in patients with hollow viscus perforation and to examine the influence of these microorganisms on the outcome. A prospective study was conducted from May 2005 to September 2006 involving 84 consecutive patients with spontaneous gastrointestinal perforation peritonitis, who were referred for surgery. Peritoneal fluid was analyzed by microbial culture and biochemical tests for bacteria and fungi. The Jabalpur Prognostic Score was calculated. Forty-two of the 84 patients had positive peritoneal fluid cultures. Escherichia coli was the most common bacterium (n=26) and Candida (n=13) the most common fungus isolated. Bacterial isolates were largely sensitive to amikacin while all the Candida isolates were sensitive to fluconazole. Mortality was significantly higher in patients with positive peritoneal cultures (15/42) compared with those with negative peritoneal cultures (0/42, p<0.001), and in patients with mixed bacterial and fungal-positive cultures (10/13) compared with those with isolated bacterial cultures (5/29, p<0.001). Using the Jabalpur Prognostic Score, positive fungal cultures were found to be associated with a significantly higher than expected mortality. Patients with gastrointestinal perforations and positive peritoneal cultures have a poor prognosis, which is significantly worsened by the association of positive fungal cultures. Early recognition and treatment of fungal infection is advisable.

A simplified prognostic scoring system for peptic ulcer perforation in developing countries.

BACKGROUND: Several complex prognostic scoring systems are available for abdominal sepsis. We constructed and assessed a simplified scoring system for peptic perforation, which can be easily used in developing countries. METHODS: One hundred and forty consecutive patients with perforated pre-pyloric or duodenal ulcer undergoing Graham's patch omentopexy closure were studied prospectively. Each factor was given a score based on its severity in accordance with the APACHE-II scoring system to construct the simplified prognostic (Jabalpur) scoring system, and multiple regression analysis was used to identify risk factors. This system was prospectively validated in the next 50 consecutive patients and compared to existing systems. RESULTS: The factors associated with mortality were age, presence of co-morbid illness, perforation-to-operation interval, preoperative shock, heart rate, and serum creatinine. The mean score in survivors (4.9) was less than that in those who died (12.5; p<0.0001). This scoring system compared favorably with other scoring systems. CONCLUSIONS: The Jabalpur scoring system is effective for prognostication in cases of peptic perforation. It is simple and user-friendly as it uses only six routinely documented clinical risk factors.
