Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for the treatment of advanced epithelial and recurrent ovarian carcinoma: a single center experience.

BACKGROUND: With standard treatment of epithelial ovarian cancer (EOC), prognosis is very poor. The aim of this study is to show early and late results in patients who underwent cytoreductive surgery and intraperitoneal chemotherapy. PATIENTS AND METHODS: This was a retrospective single centre study. All patients with advanced and recurrent ovarian cancer treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) or modified early postoperative intraperitoneal chemotherapy (EPIC) were included in the study. RESULTS: In the period 1995-2014, 116 patients were treated, 55 with primary EOC and 61 with recurrent EOC. The mean age was 59 years (26-74). Statistically, median survival time was significantly longer in the group with primary advanced cancer of the ovary (41.3 months) compared to relapsed ovarian cancer (27.3 months). Survival for the primary EOC was 65 and 24% at 3 and 5 years, respectively. Survival for recurrent EOC was 33 and 16% at 3 and 5 years, respectively. Mortality was 1/116 (0.8%). Morbidity was 11/116 (9.5%). Peritoneal cancer index (PCI) was ≤20 in 59 (51%) patients and statistically, their average survival was significantly longer than in the group of 57 (49%) patients with PCI >20 (p = 0.014). CONCLUSIONS: In advanced or recurrent EOC, a curative therapeutic approach was pursued that combined optimal cytoreductive surgery and intraperitoneal chemotherapy. PCI and timing of the intervention (primary or recurrent) were the strongest independent prognostic factors.

Laparoscopic approach in the treatment of splenic angiolipomatous hamartoma: the first report of a case.

Angiolipomatous hamartoma is a benign mesenchymal proliferation of unknown aetiology. Only a few cases have been documented in the published literature. This current case report describes a 57-year-old female patient who was hospitalized for an assessment of a previously radiologically-verified splenic lesion and further treatment. The patient had been surgically treated 10 years previously; a lobectomy of the superior left pulmonary lobe had been performed in order to remove a verified tumour lesion. A complete radiological examination was undertaken, which verified a spleen of a size that was within the physiological range, with a centrally-located lobular tumour lesion. Given the risk of splenic rupture, as well as the fact that the lesion's aetiology was still undetermined, and finally the fact that differential diagnostics indicated the possibility of a metastasis, the patient was treated surgically. Laparoscopic splenectomy, in the treatment of splenic diseases, even rare ones such as this, is not a novelty. Indeed, it needs to be applied as the standard approach, with the well-known benefits that the minimalized approach offers.

Complications during the establishment of laparoscopic pneumoperitoneum.

BACKGROUND: A safe establishment of the laparoscopic pneumoperitoneum is of the utmost importance, as potentially fatal complications, such as vascular or visceral injury or gas embolism, may occur during the procedure. OBJECTIVE: We used the published studies and our own experience to evaluate the advantages and disadvantages of various techniques for the establishment of the laparoscopic pneumoperitoneum, thus aiming to contribute to the reduction in the rate of fatal complications. METHODS: We performed a retrospective review of 4940 medical charts of patients without prior history of abdominal surgeries who had the laparoscopic pneumoperitoneum established by using a modified closed method (i.e., the patient is in an anti-Trendelenburg's position 20-30 degrees and a left lateral tilt of 10-15 degrees, with the Veress needle and the first trocar introduced through the umbilicus and directed toward the intersection of the anterior axial line and the right costal arc). Additionally, we searched Medline, Embase, and the Cochrane libraries with a cut-off date of December 2006, using specific key-words (i.e., trocar injury, complication, laparoscopic surgery, Veress needle, open vs. closed pneumoperitoneum, prospective study). RESULTS: There were no reports of injuries to the major blood vessels or visceral organs. However, liver capsule injury was reported in 432 (8.2%) patients, pneumo-omentum in 55 (1.1%) patients, and subfascial insufflations in 45 (0.9%) patients. CONCLUSIONS: No reliable conclusions regarding advantages or disadvantages of different techniques for the laparoscopic pneumoperitoneum can be drawn in the absence of adequately powered, prospective, comparative studies. Based on the fact that no major blood vessel or visceral organ injuries were observed in our experience, we conclude that the modified closed method deserves further multicentric prospective evaluation.

Double-barreled wet colostomy: urinary and fecal diversion.

PURPOSE: Double-barreled wet colostomy represents simultaneous urinary and fecal surgical diversion performed most commonly after pelvic exenteration as a palliative procedure or after actinic damage. We report the structural and functional results of double-barreled wet colostomy with special attention to surgical technique, morbidity and functional results compared to those described in the available literature. MATERIALS AND METHODS: We retrospectively followed 38 patients who underwent double-barreled wet colostomy at our institution from April 2003 to November 2007. The parameters were patient age and gender, the indication for double-barreled wet colostomy, postoperative morbidity and mortality, length of hospital stay and functional assessment by excreting excretory urography. RESULTS: A total of 38 double-barreled wet colostomies were performed at our institution, including 24 following total pelvic exenteration, 14 without resection, 9 in inoperable tumor cases and 5 in actinic damage cases. The postoperative morbidity rate was 15.7% with no treatment related mortality. Two patients had late postoperative complications, including stenosis of the ureterocolonic anastomosis and conduit necrosis, respectively. CONCLUSIONS: In our experience double-barreled wet colostomy has an acceptable morbidity and mortality rate, is performed without technical difficulties and does not require prolonged operative time. Double-barreled wet colostomy represents the procedure of choice in patients who require concurrent urinary and fecal diversion.

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.

Serum Level of HMGB1 Protein and Inflammatory Markers in Patients with Secondary Peritonitis: Time Course and the Association with Clinical Status.

BACKGROUND: Intra-abdominal infection in secondary peritonitis drives as excessive production of inflammatory mediators and the development of systemic inflammatory response syndrome (SIRS) or sepsis. Finding a specific marker to distinguish SIRS from sepsis would be of immense clinical importance for the therapeutic approach. It is assumed that high-mobility group box 1 protein (HMGB1) could be such a marker. In this study, we examined the time course changes in the blood levels of HMGB1, C-reactive protein (CRP), procalcitonin (PCT) and serum amyloid A (SAA) in patients with secondary peritonitis who developed SIRS or sepsis. METHODS: In our study, we evaluated 100 patients with diffuse secondary peritonitis who developed SIRS or sepsis (SIRS and SEPSIS group) and 30 patients with inguinal hernia as a control group. Serum levels of HMGB1, CRP, PCT, and SAA were determined on admission in all the patients, and monitored daily in patients with peritonitis until discharge from hospital. RESULTS: Preoperative HMGB1, CRP, PCT and SAA levels were statistically highly significantly increased in patients with peritonitis compared to patients with inguinal hernia, and significantly higher in patients with sepsis compared to those with SIRS. All four inflammatory markers changed significantly during the follow-up. It is interesting that the patterns of change of HMGB1 and SAA over time were distinctive for SIRS and SEPSIS groups. CONCLUSIONS: HMGB1 and SAA temporal patterns might be useful in distinguishing sepsis from noninfectious SIRS in secondary peritonitis.

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.
