Randomized Controlled Trial of Conventional Carbon Dioxide Pneumoperitoneum versus Gasless Technique for Laparoscopic Cholecystectomy
Nikhil Talwar, Rahul Pusuluri, Mohinder Paul Arora, Mridula Pawar
JK Science : Journal of Medical Education & Research , 2006,
Abstract: Concerns about pathophysiologic changes and disadvantages associated with carbon dioxidepneumoperitoneum during laparoscopic cholecystectomy have led to the introduction of gasless laparoscopyemploying abdominal wall lifting (AWL) method. However, AWL has been criticized for its complexityand technical difficulty. We have used AWL method for gasless laparoscopic cholecystectomy and comparedit with laparoscopic cholecystectomy with respect to operation performance, postoperative course, andpathophysiologic changes. During a four-month period, 40 consecutive patients with symptomatic gallstoneswere randomly assigned to receive laparoscopic cholecystectomy with conventional CO2 pneumoperitoneum(PP group; N=20) or the AWL method (AWL group; N=20). Operative results and operative time wererecorded. Cardiopulmonary and ventilatory functions were assessed during the surgery. Postoperativepain and presence of nausea and vomiting were assessed for 48 hours after surgery. Postoperative time torecovery of flatus, tolerance to a full oral diet, and full activity were also determined. The intraoperativecardiopulmonary and ventilatory functions deteriorated significantly less in the AWL group. The preparationtime for surgery and total operative time were significantly greater in the AWL group. None of the patientsin either group required conversion to open surgery. Technique related morbidity was minimal and therewas no mortality in either group. Although AWL method required a longer operation time, our resultssuggest that the technique is valuable in high-risk patients with cardiorespiratory disease. AWL techniqueof laparoscopic cholecystectomy is a feasible, safe and effective alternative to CO2 pneumoperitoneum. Itprobably costs less and is therefore, more useful in developing countries.
Primary Extra-Gastrointestinal Stromal Tumor (GIST) arising from mesentery of small bowel and presenting as abdominal mass: A rare entity  [PDF]
Alok Kumar Tiwari, Anil Kumar Choudhary, Hemant Khowal, Poras Chaudhary, Mohinder P. Arora
Open Journal of Gastroenterology (OJGas) , 2013, DOI: 10.4236/ojgas.2013.35045
Abstract: Introduction: Majority of mesenchymal tumors of gastrointestinal tract are Gastrointestinal Stromal Tumor (GIST). It is, however, a rare tumor, accounting for less than 1% of primary gastrointestinal (GI) neoplasms. Though, these tumors are refractory to conventional chemotherapy or radiotherapy but show a good response to targeted adjuvant chemotherapy with tyrosine kinase inhibitors following surgical resection. Case Report: we report here a case of primary Extra-GIST tumor arising from mesentry of small bowel near duodeno-jejunal junction in a 69 years old male patient. The patient presented with a palpable mass in upper abdomen for past 15 days. On examination, a non-tender mobile lump of size around 17 × 10 cm, with bosselated surface and firm in consistency was palpable involving epigastric, left hypochondrium and umbilical region. Contrast enhanced computed tomography of abdomen revealed a heterogenous mesentric mass. On surgical intervention a mass was found involving mesentery near dudenojejunal junction without involvement of gastrointestinal tract. Complete surgical resection of the tumor was done and adjuvant chemotherapy with Imatinib mesylate was started as HPE revealing GIST with mitotic index of >10/50 HPF and 17 × 10 cm size placed the patient in high risk category. Patient was discharged on 12th of post-operative day with advice of regular follow-up. Conclusion: GIST occurrence is not restricted to bowel but can involve unusual sites also. The mainstay of treatment remains surgical resection with adequate margin. In cases where tumour has malignant potential (high mitotic figures on histopathology) adjuvent treatment with tyrosine kinase may prevent or delay relapse.
An Algorithmic Approach to the Extensibility of Association Schemes
Manuel Arora,Paul-Hermann Zieschang
Computer Science , 2012,
Abstract: An association scheme which is associated to a height t presuperscheme is said to be extensible to height t. Smith (1994, 2007) showed that an association scheme X=(Q,\Gamma) of order d:=|Q| is Schurian iff X is extensible to height (d-2). In this work, we formalize the maximal height t_max(X) of an association scheme X as the largest positive integer such that X is extensible to height t (we also include the possibility t_max(X)=\infty, which is equivalent to t_max(X)\ge (d-2)). Intuitively, the maximal height provides a natural measure of how close an association scheme is to being Schurian. For the purpose of computing the maximal height, we introduce the association scheme extension algorithm. On input an association scheme X=(Q,\Gamma) of order d:=|Q| and an integer t such that 1\le t\le (d-2), the association scheme extension algorithm decides in time d^(O(t)) if the scheme X is extensible to height t. In particular, if t is a fixed constant, then the running time of the association scheme extension algorithm is polynomial in the order of X. The association scheme extension algorithm is used to show that all non-Schurian association schemes up to order 26 are completely inextensible, i.e. they are not extensible to a positive height. Via the tensor product of association schemes, the latter result gives rise to a multitude of examples of infinite families of completely inextensible association schemes.
Efficacy of Slow Reversal Hold and Isometrics in Improving Muscle Strength, Increasing Range of Motion, and Reducing Pain in Patients with Osteoarthritis of Knee  [PDF]
Harneet Arora
Health (Health) , 2018, DOI: 10.4236/health.2018.105043
Abstract: Osteoarthritis of knee is a common problem in the elderly population worldwide. Physical therapy has been shown to be useful in decreasing pain and increasing mobility in this population. The aim of this study was to study the effectiveness of slow reversal hold and isometric exercise techniques in reducing pain, increasing muscle strength, and increasing range of motion for knee flexion in patients with osteoarthritis of knee. The other aim of this study was to compare the relative effectiveness of these two interventions. 60 subjects participated in this study and were randomly assigned either to the slow reversal hold group (n = 30) or, to the isometrics exercise group (n = 30). All subjects performed their respective exercises for 3 weeks. Pain scores using the visual analog scale, muscle strength using manual muscle testing of quadriceps and hamstrings, and range of motion (ROM) for knee flexion using a goniometer were recorded both pre-treatment and post-treatment for both left and right knees. Both the interventions showed a significant decrease in pain scores, an increase in muscle strength, as well as an increase in the ROM. However, ROM was significantly increased in the slow reversal hold group as compared to the isometrics group in both knees. It was concluded that both exercise techniques could be useful in patients with osteoarthritis of knee for decreasing pain and increasing muscle strength. Slow reversal hold technique might be a better technique than isometrics for increasing ROM for knee flexion.
Cold Abscess of the Anterior Abdominal Wall: An Unusual Primary Presentation
Mohinder Kumar Malhotra
Nigerian Journal of Surgery , 2012,
Abstract: Tuberculosis is considered as ubiquitous disease as it involves any organ, but primary involvement of abdominal muscles is very rare. In most cases, the muscle involvement is secondary and is caused by either hematogenous route or direct inoculation from a tuberculous abdominal lymph node or extension from underlying tubercular synovitis and osteomyelitis. Autopsy studies have shown abdominal wall involvement in less than 1% of patients who died of tuberculosis. Antitubercular therapy is main form of management. Surgical intervention is always secondary in the form of either sonography or computerized tomography-guided aspiration or open drainage which is usually reserved for patients in whom medical treatment has failed. A case is hereby reported about primary tubercular anterior abdominal wall abscess without any evidence of pulmonary, skeletal or gastrointestinal tuberculosis in an apparently healthy individual with any past history of contact or previous antituberculosis therapy.
Migratory Surgical Gossypiboma—Cause of Iatrogenic Perforation: Case Report with Review of Literature
Mohinder Kumar Malhotra
Nigerian Journal of Surgery , 2012,
Abstract: Forgotten foreign bodies, such as cotton sponges, gauze, or instruments, after any surgical procedure is considered a misadventure but avoidable complication. “Gossypiboma” denotes a mass of cotton that is accidentally retained in the body postoperatively. This study’s goal was to systematically review the literature on retained sponges to identify incidence, site of occurrence, time of discovery, methods for detection, pathogenesis for intraluminal migration and risk factors. Author is reporting this case in which a 45-year old woman presented with features of chronic pain abdomen following abdominal hysterectomy (first surgery) which lead to open cholecystectomy (second surgery) after two and half year of first surgery. As patients continued to have persistent abdominal pain in spite of second surgery patient went to medical gastroenterologist who advised her series of tests including colonoscopy examination. The whole colon was normal on examination but on examination of terminal portion of small bowel some intraluminal mass was visualized. Attempt to retrieve this mass lead to iatrogenic ileal perforation.
