ABSTRACT
BACKGROUND: Laparoscopic port entry is crucial and vital step in any laparoscopic surgery. As laparoscopy is widely used, complications related to it are also increasing which are not seen in conventional laparotomy. AIM: The present study was undertaken to compare the ease of primary trocar entry after pneumoperitoneum at 20 mmHg pressure and direct trocar entry without pneumoperitoneum. METHODS: Total 100 nulliparous patients who presented for elective gynaecologic laparoscopic surgery were enrolled for the study. In operating theatre, randomization of patients was done using a sealed envelope technique which divides patients into two equal groups and assigned as either low-pressure group or high-pressure group. Verres needle insertion and trocar entry was done by fellowship trainee in laparoscopy assisted by senior laparoscopy surgeon. RESULT: In high-pressure group we had trocar entry in first attempt in 80% of patient, second attempt in 20% where as in direct trocar entry group required first attempt in 88%, second attempt in 10% and third attempt in 2%. Time taken for trocar entry between two groups was significantly different requiring 4.42 ± 0.55 min for high pressure and 1.2 ± 0.28 min for direct trocar entry. CONCLUSION: The study concluded that high-pressure trocar entry requires more time; require less attempts, easier and surgeon will be more comfortable in repeating the same technique than direct trocar entry.
ABSTRACT
BACKGROUND AND AIMS: During routine preoperative assessment of patients one of the commonest practices is predicting difficulty of intubation. The present study was undertaken to evaluate parameters associated with difficult intubation and to test on new set of patients. At the end, to form simple predictive rule to decreased the number of false alarms. MATERIAL AND METHODS: In initial series of 483 Indian population patients we measured age, sex, weight, height, interincisor gap, mandibular length, neck movement, neck circumference, subluxation of mandible, sternocricoid distance, and identified factors associated with difficult intubation. These were applied on next 480 patients of prospective series and simple predictive rule in form of risk sum score was developed. RESULTS: After analyzing initial series data we found that weight (P = 0.033), height (P = 0.034), interincisor gap (P = 0.005), subluxation (P < 0.001), neck movement (P < 0.001), and sternocricoid distance (P = 0.020) were significantly associated with difficult intubation. These six factors were applied on next set of 480 patients to found accuracy of predicting difficult intubation of weight (51.7%), height (83.8%), interincisor gap (80.2%), subluxation (77.7%), neck movement (82.7%), and sternocricoid distance (79.2). Total score greater than 2 predicted 92.8% of difficult laryngoscopies correctly as against 33.9% would be falsely labeled as difficult. CONCLUSION: Interincisor gap and sternocricoid distance are the two most sensitive factors predicting difficult intubation in Indian patients. However, risk sum score of more than 6 may lead to better anticipation of truly difficult intubations.
ABSTRACT
OBJECTIVE: The objective of the study was to assess the fetal outcome after receiving intrauterine transfusion (IUT) in Rh-isoimmunized pregnancy in a tertiary care center. STUDY DESIGN: This was a retrospective observational descriptive study in which all Rh-negative gravidas with isoimmunization warranting IUTs (40 patients) were analyzed during the period from January 1, 2010 to October 31, 2015. Primary outcome variables were fetal outcomes and procedural-related factors. RESULTS: Forty pregnancies (13-hydropic, 27-non-hydropic) required 74 IUTs. IUT was performed at gestational age of 15.4-33 weeks when indicated. The amount of blood transfused ranged from 4 to 110 ml. There were two sudden intrauterine fetal deaths during the procedure, four post-procedure intrauterine fetal deaths in fetuses with severe hydrops, and three neonatal deaths. The overall survival rate was found to be 77.5%. CONCLUSION: IUT was found to be an effective therapy in correcting anemia in fetuses of Rh isoimmunized mothers. Early diagnosis of fetal anemia and intrauterine blood transfusion by an experienced fetal medicine specialist is very important for the perinatal outcome.
ABSTRACT
CONTEXT: Host of vaginoplasty techniques have been described. None has been successful in developing normal vagina. Laparoscopic peritoneal vaginoplasty (LPV) is performed in Mayer-Rokitansky-Küster-Hauser syndrome (MRKHS) culminating in normal vagina. AIMS: This study aims to confirm normal development of neovagina by anatomical and functional parameters of histology, cytology, and ultrasonography (USG) in LPV. To identify peritoneal progenitor cell by OCT4/SOX2 markers. To demonstrate the metaplastic conversion of peritoneum to neovagina and the progenitor cell concentration, distribution pattern. SETTINGS AND DESIGN: This is prospective experimental study, conducted at teaching hospital and private hospital. SUBJECTS AND METHODS: Fifteen women of MRKHS underwent LPV followed by histology, cytology, two-/three-dimensional USG of neovagina. Four women underwent peritoneal biopsy for identification of progenitor cells with OCT4/SOX2 markers. One patient underwent serial biopsies for 4 weeks for histology and progenitor cell immunohistochemistry. RESULTS: Normal vaginal histology and cytology were apparent. USG of neovagina showed normal appearance and blood flow. Two peritoneal samples confirmed the presence of progenitor cells. Serial biopsies demonstrated the epithelial change from single to multilayer with stromal compaction and neoangiogenesis. The progenitor cells concentration and different distribution patterns were described using SOX2/OCT4 markers. CONCLUSIONS: We have shown successful peritoneal metaplastic conversion to normal vagina in LPV. The progenitor cell was identified in normal peritoneum using SOX2/OCT4 markers. The progenitor cell concentration and pattern were demonstrated at various stages of neovaginal development.
