Coronary artery revascularization prior to abdominal nonvascular surgery.

BACKGROUND: Does preoperative revascularization of the myocardium reduce cardiac risk in noncardiac surgery? The aim of this study was to evaluate the clinical effectiveness of preoperative cardioprotection by coronary artery revascularization in abdominal nonvascular surgery under general anesthesia. MATERIALS AND METHODS: The observational clinical study included 111 consecutive patients with angiographically verified coronary artery disease. Two stratification groups of patients were compared, those with coronary artery revascularization (34 patients, 30.6%) and those without coronary artery revascularization (77 patients, 64.9%), in relation to frequency of perioperative cardiac complications. The patients were followed up until the 30th postoperative day. During operation and in the following 72 postoperative hours, the patients were monitored by continuous ST-T segment recording. Twelve-lead electrocardiography was performed immediately after surgery and on postoperative days 1, 2, and 7 as well as 1 day before discharge. Serum troponin T levels were controlled at 6, 24, and 96 h postoperatively. RESULTS: The number of patients with major cardiac complications was 0 (0.0%, n=34) in the revascularized myocardium group and 10 (12.9%, n=77) in the nonrevascularized myocardium group (P<.05). Three patients in the nonrevascularized myocardium group died of acute myocardial infarction, congestive heart failure, and malignant arrhythmias, respectively, with severe coronary artery stenosis verified angiographically. CONCLUSIONS: Preoperative cardioprotection by coronary artery revascularization significantly reduces morbidity and mortality in patients who have undergone abdominal nonvascular surgery. Patients with severe coronary artery stenosis and indication for coronary artery revascularization independently of noncardiac surgery should first undergo cardiosurgical intervention prior to elective abdominal nonvascular surgery.

[The use of recombinant activated factor VII to control haemorrhage following exenteration and massive transfusion in coagulopathic patients].

INTRODUCTION: Exentheresis pelvis totalis due to locally advanced pelvic malignancies is an extensive surgical procedure. The operation is commonly associated with anticipated perioperative haemorrhage requiring a large volume of haemoproducts. Sometimes, the intervention can result in unexpected massive and uncontrolled haemorrhage that is frequently a combination of surgical and coagulopathic bleeding. Attempts to arrest massive bleeding by conventional means may fail. CASES OUTLINE: We describe our experience in the use of recombinant activated factor VII (rFVIIa) in three previously hemostatically competent patients who underwent exentheresis in order to control massive bleeding resulting from dilution coagulopathy in the operating theatre, as well as in the treatment of postoperative bleeding associated with consumptive coagulopathy. Of these, two massively transfused patients developed dilution coagulopathy in the operative theatre, which was poorly responsive to conventional management. In both cases, a single dose of rFVIIa (70 microg/kg and 60 microg/kg respectively) was given. Prompt clinical response was achieved and operations were successfully finished. In the third case, the patient developed consumptive coagulopathy on the first day after surgical procedure that was treated with conventional therapy. On the second postoperative day the patient became anuric and experienced severe intraabdominal bleeding. The bleeding was successfully controlled with rFVIIa in a single dose of 70 microg/kg. CONCLUSION: RFVIIa can be a treatment option in patients suffering from intractable coagulopathic bleeding when standard therapy has failed.

Hemodynamic and cardiovascular problems during modified hyperthermic intraperitoneal perioperative chemotherapy.

BACKGROUND/AIMS: Cytoreductive surgery and hyperthermic intraperitoneal perioperative chemotherapy (HIPEC) significantly improves patients survival with peritoneal carcinomatosis especially in low-grade tumor e.g. ovarian and appendiceal adenocarcinoma, peritoneal pseudomyxoma and grade I gastric and colorectal cancer. METHODOLOGY: During a period of nine years, hemodynamic and cardiac functions combined with urinary output during hyperthermic intraoperative intraperitoneal chemotherapy were prospectively measured in 60 patients. RESULTS: Statistically significant hemodynamic and cardiac parameters were characterized by an increased heart rate and cardiac output as well as decreased systemic vascular resistance associated with an increased body temperature and decreased effective circulating volume. The tendency of urinary output was to decrease as the therapy progressed. CONCLUSIONS: HIPEC induces a hyperdynamic circulatory state requiring increased intravenous fluid administration, which avoids changes because of increased intra-abdominal pressure. Documented by normal blood pressure and adequate urinary output hemodynamic and intravenous fluids, titrated to frequent urinary output determination, can achieve cardiac stability.

Bulk agent Plantago ovata after Milligan-Morgan hemorrhoidectomy with Ligasure.

The aim of this study was to determine usefulness of the bulk agent Plantago ovata in reducing postoperative pain and tenesmus after open hemorrhoidectomy (Milligan-Morgan with Ligasure). Ninety-eight patients were randomized into two groups of 49 patients each. In both groups Milligan-Morgan open hemorrhoidectomy with Ligasure was performed. The first group received postoperatively two sachets daily of 3.26 g of the bulk agent, Plantago ovata, for 20 days. The control group was treated postoperatively with glycerin oil. There was no statistically significant difference in age, gender distribution and hemorrhoid grading, between the two groups. The pain score after first defecation (p < 0.001) and after 10 days (p < 0.01) and the global pain score (p < 0.001) was statistically significantly lower in the group treated with Plantago ovata, while there was no statistically significant difference in the pain level after 20 days (p > 0.05). The hospital stay was statistically significantly shorter in the group receiving Plantago ovata (2.6 +/- 0.6 vs 3.9 +/- 0.7 days, p < 0.001). The incidence of tenesmus was higher in the control group (40.8% vs 10.2%, p < 0.01). Treating patients with Plantago ovata after open hemorrhoidectomy, reduces pain, tenesmus rate and shortens postoperative hospital stay.

[Transcholedochal pancreatic fistula]. / Transholedohusna fistula pankreasa.

Pancreatic fistula is usually caused by acute or chronic pancreatitis, injury and operations of the pancreas. The pancreatic juice comes either from the main pancreatic duct or from side branches. Extremely rare pancreatic fistula may come through the distal end of the common bile duct that is not properly sutured or ligated after traumatic or operative transsection. We present a 58-year old man who developed a life threatening high output pancreatic fistula through the distal end of the common bile duct that was simply ligated after resection for carcinoma. Pancreatic fistula was developed two weeks after original surgery and after two emergency reoperations for serious bleeding from the stump of the right gastric artery resected and ligated during radical lymphadenectomy. The patient was treated conservatively by elevation of the drainage bag after firm tunnel round the drain was formed so that there was no danger of spillage of the pancreatic juice within abdomen.
