Interrupted abdominal closure prevents burst: randomized controlled trial comparing interrupted-x and conventional continuous closures in surgical and gynecological patients.

Reduction in the risk of abdominal dehiscence with application of interrupted method of laparotomy closure and comparison with risk of burst with continuous method of closure. Three hundred forty eight patients undergoing laparotomy (114-elective gynecology, 114-emergency gynecology, 120-emergency surgery) were randomized into three arms to undergo closure with continuous, interrupted-X, and Modified Smead-Jones suturing techniques. Burst abdomen occurring up to 4 weeks of operation. Twenty-nine (8.33 %) of 348 patients developed burst in the post-operative period. 19 (15.70 %) of 121 patients in continuous arm developed burst. Five of 110 (4.55 %) patients in Interrupted-X arm and 5 of 117 (4.27 %) patients in Modified Smead-Jones arm developed burst. Interrupted suturing was associated with significant reduction in risk of burst when compared with continuous closure. Important predictors of burst were Intraperitoneal sepsis, cough, uremia, and surgical site infection.

Predictive factors for successful early laparoscopic cholecystectomy in acute cholecystitis: a prospective study.

BACKGROUND: Early laparoscopic cholecystectomy has become the treatment of choice for acute cholecystitis. However, the rate of intraoperative conversion to open surgery remains high and has provoked an interest in studying the predictive factors for better patient selection to minimize the conversion rates. MATERIALS AND METHODS: 50 patients of acute cholecystitis were operated within 5 days of onset of symptoms. Comparative evaluation of the patient groups undergoing successful versus failed early laparoscopic cholecystectomy was done to identify preoperative factors predicting conversion/failure of the laparoscopic procedure. Predictive factors for intraoperative and histopathological severity of acute cholecystitis were also identified. RESULTS: 40 patients underwent successful completion of early laparoscopic cholecystectomy, 8 required conversions to open, while in 2 patients the procedure had to be abandoned due to phlegmon formation. Male sex, preoperative duration of symptoms WBC counts, serum alkaline phosphatase, serum amylase, and serum C-reactive protein were significant predictors of histopathological severity of acute cholecystitis. Intraoperative and histopathological severity of acute cholecystitis had good association with conversion rate of early laparoscopic cholecystectomy. Male sex and serum C-reactive protein levels >3.6 mg/dl at admission were very strong predictors of conversion/failure of early laparoscopic cholecystectomy in acute cholecystitis. CONCLUSION: Male patients of acute cholecystitis or patient with serum C-reactive protein levels of >3.6 mg/dl at admission have high risk of conversion in early laparoscopic cholecystectomy and warrant a conservative early management followed by delayed laparoscopic cholecystectomy.

Role of prophylactic antibiotics in laparoscopic cholecystectomy and risk factors for surgical site infection: a randomized controlled trial.

BACKGROUND: The aim of this clinical trial was to determine whether prophylactic antibiotics could prevent surgical site infection (SSI) after laparoscopic cholecystectomy and to identify any risk factors for infection. METHODS: The study included 100 patients undergoing laparoscopic cholecystectomy. They were randomized to receive either a single dose of ceftriaxone (Group A; n = 50) or physiologic saline as placebo (Group B; n = 50) after the induction of anesthesia. Patient demographics and clinical and surgical outcomes were recorded. RESULTS: The incidence of SSI was similar in the two groups: 2 patients in group A and 4 patients in group B (chi(2) = 0.71; p = 0.40). None of the factors studied was associated with surgical site infection statistically, as shown by binary logistic regression analysis. CONCLUSION: A single dose of prophylactic antibiotic failed to decrease the likelihood of SSI after laparoscopic cholecystectomy.

Breast cancer: interaction between oxidant-antioxidant dynamics and inflammation in Indian females.

OBJECTIVES: Oxidative stress and pro-inflammatory mediators have been implicated in breast carcinogenesis. We attempted to evaluate the markers of oxidative stress, antioxidant mechanism and the inflammatory pathway in patients with breast cancer. METHODS: This study was carried out in departments of Biochemistry and Surgery, Maulana Azad Medical College and associated Hospitals, New Delhi, India. A total of 60 cases of carcinoma of the breast and 60 healthy controls were included in the study. The parameters that were assayed include markers of oxidative stress-conjugated dienes, thiobarbitone reactive substances (TBARS), antioxidants-superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), glutathione (GSH) and markers of inflammation-interleukin-6(IL-6) and ferritin. RESULTS: There was a significant decline in the antioxidant levels and a significant rise in oxidant levels in patients with carcinoma of the breast, compared to controls. The inflammatory markers-IL-6 and ferritin-were also significantly higher in patients with breast cancer. A significantly positive correlation was observed between the IL-6 levels and conjugated dienes with the stage of breast carcinoma; whilst a significantly negative correlation was observed between the levels of conjugated dienes and superoxide dismutase and superoxide dismutase levels with the disease staging. CONCLUSIONS: This study underlines the interplay between inflammatory pathways and oxidative stress in the pathogenesis of breast cancer. MINI ABSTRACT: An intense research is underway to identify the possible risk factors and the molecular mechanisms involved in pathogenesis of breast cancer. Inflammation and oxidative stress are two such etiologies investigated in our study.

Subcutaneous and breast metastasis from asymptomatic gallbladder carcinoma.

BACKGROUND: Though gallbladder carcinoma is associated with early lymphatic and hematogenous spread, the only common extra-abdominal site of metastasis is lung. Gallbladder carcinoma metastasizing to breast and subcutaneous tissue is not known. METHOD: This report describes an interesting and unusual case of asymptomatic gallbladder carcinoma presenting with subcutaneous and breast metastasis. RESULTS: A 42-year-old woman presented with multiple subcutaneous nodules over the abdominal wall, anterior chest wall, back and in bilateral breasts. Fine needle aspiration cytology (FNAC) of these nodules revealed metastatic adenocarcinoma. The patient was investigated for a primary neoplasm. An ultrasound of the abdomen followed by a contrast-enhanced CT scan showed a growth in gallbladder, infiltrating the liver with multiple hepatic metastases. CT-guided FNAC from the growth in the gallbladder revealed adenocarcinoma. She was diagnosed as a case of metastatic adenocarcinoma of the gallbladder and palliative combination chemotherapy with gemcitabine and carboplatin was given. But she developed jaundice and deteriorated dramatically in a short span of time. No specific therapy could be started and she was given supportive treatment. She died within three weeks of diagnosis due to hepatic encephalopathy. CONCLUSIONS: This report highlights an unusual metastasis of gallbladder carcinoma to the breast and subcutaneous tissue presenting as multiple lesions, which has never been reported in the English literature. These were unknown sites of metastasis for carcinoma of the gallbladder. Moreover, bilateral multiple metastatic lesions to breast are also very rare.

Alteration in coagulation profile and incidence of DVT in laparoscopic cholecystectomy.

INTRODUCTION: Although laparoscopic cholecystectomy appears to be less traumatic to the patients than open surgery, decreased venous return from lower extremities and hypercoagulability occurring in patients undergoing elective laparoscopic cholecystectomy with CO(2) pneumoperitoneum makes it a potent risk factor for deep venous thrombosis. METHODS: The observational study of 50 patients undergoing elective laparoscopic cholecystectomy was designed to study alteration in PT, APTT, D-dimer and antithrombin III, which were measured preoperatively, 6 and 24h postoperatively. It was accompanied by color duplex ultrasound of bilateral lower limbs preoperatively and 7th day postoperatively to look for evidence of deep venous thrombosis. RESULTS: Significant postoperative decrease in APTT and antithrombin III suggested activation of coagulation while decrease in d-dimer suggested activation of fibrinolysis. Values of PT had no statistically significant postoperative changes. Age, body mass index and duration of pneumoperitoneum were found to correlate with significant activation of coagulation and fibrinolysis. None of the patients developed clinical or radiological evidence of deep venous thrombosis in the postoperative period. CONCLUSIONS: CO(2) pneumoperitoneum enhances the activation of coagulation and fibrinolysis associated with laparoscopic cholecystectomy. Patients with risk factors like old age, obesity or with expected long duration of laparoscopic surgery are likely to have significant activation of coagulation, making them a vulnerable risk group for development of postoperative deep vein thrombosis, warranting some form of thromboprophylaxis.

Randomized controlled trial to assess the role of raised anal pressures in the pathogenesis of symptomatic early hemorrhoids.

BACKGROUND: Increased maximum resting anal pressures (MRAP) have been found in patients with large prolapsed hemorrhoids undergoing hemorrhoidectomy, but their pathogenic role is controversial especially in view of the sphincteric damage that occurs with open and stapled procedures. This prospective randomized clinical trial was conducted to compare anal pressure changes in early symptomatic hemorrhoidal disease before and after successful treatment with band ligation or injection sclerotherapy, and to compare these pressures with those in normal asymptomatic controls. METHODS: 32 patients with symptomatic grade II hemorrhoids were randomized to treatment with either band ligation or injection sclerotherapy. Anal manometry was done before treatment and 8 weeks after completion of treatment, and compared with 20 normal age-matched controls. RESULTS: The pretreatment values in both study groups were similar to each other (69.38 cm H(2)O, 95% CI 58.67-80.08, vs. 67.75 cm H(2)O, 95% CI 56.86-78.64; p = 0.790), but were significantly higher (p = 0.0001 in both groups) than in the controls (45.25 cm H(2)O, 95% CI 38.36-52.14). After successful completion of treatment, there was a highly significant drop in the MRAP in both study groups (p = 0.0001 in group A, and p = 0.001 in group B) reaching normal values. CONCLUSIONS: Our study shows that even in early-stage hemorrhoids, the anal pressures are significantly raised, but after successful treatment with band ligation or injection sclerotherapy, these pressures return to normal, showing that they do not play a pathogenic role but are secondary to the congested hemorrhoidal cushions.

Topical nitroglycerin versus lateral internal sphincterotomy for chronic anal fissure: prospective, randomized trial.

INTRODUCTION: Topical nitroglycerin (GTN) is one of the medical treatments of choice in chronic anal fissure. The present prospective, randomized, clinical trial was conducted to study the symptomatic relief, healing, and changes in the maximum anal resting pressure (MARP) in patients with chronic anal fissure comparing topical GTN and lateral sphincterotomy. METHODS: Forty consecutive patients with chronic anal fissure were randomized for treatment with either topical GTN or internal sphincterotomy (20 patients in each group). Anal manometry was done before treatment in all patients, and 1 h after application of GTN or sphincterotomy. Patients were followed at 2-weekly intervals for 6 weeks for symptomatic relief and healing. RESULTS: Both GTN and sphincterotomy brought about a highly significant, but comparable drop in the MARP after treatment (P < 0.0001 in both groups). Sphincterotomy relieved pain much earlier compared to GTN (70% vs 40% at 2 weeks, P = 0.0032); but after 4 weeks of treatment, pain relief in both groups was comparable. Healing in the sphincterotomy group was also earlier than with GTN (55% vs 0% at 2 weeks, P < 0.0001; and 85% vs 30% at 4 weeks, P < 0.0001); but after 6 weeks, healing in both groups was comparable. Sphincterotomy had a significant incidence of minor, short-term complications; it also required surgical expertise, theatre time, and day-care beds. Nitroglycerin is safe, with mild and tolerable side-effects of headache and local burning sensation. CONCLUSION: Topical GTN should be the initial treatment in chronic anal fissure. Lateral sphincterotomy should be reserved for patients with severe disabling pain (because pain relief is much faster), and for patients not responding to at least 4 weeks of GTN therapy.

Randomized, double-blind trial comparing topical nitroglycerine with xylocaine and Proctosedyl in idiopathic chronic anal fissure.

OBJECTIVE: To compare symptomatic relief, healing, and changes in maximal anal resting pressure with the use of topical formulations in patients with chronic anal fissure. METHODS: Sixty-four consecutive patients with chronic anal fissure were randomized into 4 groups that received, in a double-blind manner, a topical ointment that contained 0.2% nitroglycerine (GTN), 5% xylocaine, Proctosedyl (hydrocortisone acetate, heparin, framycetin sulfate, esculoside, ethoform, butoform) or petroleum jelly (Vaseline), to be applied twice daily. Patients were reviewed at 2-week intervals for 6 weeks. Anal manometry was done before, and 20 minutes after, the first application of the ointment. RESULTS: There was significant (p < 0.0001) reduction in mean anal resting pressure after application of GTN, but not any other ointment. Of 16 patients receiving GTN, complete pain relief occurred in 6 and 15 patients after 2 and 4 weeks of treatment, respectively; this was more frequent than in the other 3 groups. At 6 weeks also, complete pain relief occurred more often with GTN than with Vaseline or xylocaine. After 4 weeks of treatment, 3 patients on GTN had complete healing of fissure as compared to one each in the xylocaine and Proctosedyl groups and none in the Vaseline group. At 6 weeks, healing of fissure had occurred in 15 of 16 patients receiving GTN as compared to 4 receiving Vaseline, 11 receiving xylocaine, and 12 on Proctosedyl. CONCLUSIONS: Topical nitroglycerine produces 'chemical sphincterotomy' with reduction in mean anal resting pressure. Pain relief and healing of fissure occurred earlier with GTN than with other treatments. GTN should be considered as the treatment of choice for the non-surgical management of patients with chronic anal fissure.
