Background. Now there are heteropolar opinions on influence of postoperative purulent septic complications on rectal cancer patients on the long term oncological results.
Objective. Assess influence of these complications following laparotomy and perineal wounds after operations for rectal cancer on the long term oncological results.
Methods. We performed retrospective cohort research of 338 patients undergone scheduled radical operations for middle ampullar and lower ampullar rectal cancer T1-4N0-2M0 from January, 2003 to December, 2011. Patients were distributed in two groups: with suppuration of postoperative wounds and/or abscess of the abdominal cavity (n = 44–13%) and without purulent septic complications (n = 294).
Results. The logit regression analysis has shown that suppuration of laparotomy wounds and/or abscess of the abdominal cavity is one of the independent risk factors of a systemic recurrence. For development of a local recurrence purulent septic complications were not risk factors. The five-year overall and cancer specific survival in compared groups demonstrated statistically significant distinction. The overall survival in the main group – 47%, in the control one – 67.2% (Wilcoxon’s criterion р = 0.10, Cox-Mentela’s criterion р = 0.02, log rank criterion р = 0.03). Cancer specific survival was 43.5% and 70.1% respectively (Wilcoxon’s criterion p = 0.01, Cox-Mentela’s criterion p = 0.005, log rank criterion p = 0.009). The five-year recurrence free survival in the compared groups was similar 50.6 and 69% respectively (Wilcoxon’s criterion p = 0.25, Cox-Mentela’s criterion p= 0.12, log rank criterion p = 0.12).
Conclusion. Purulent septic complications of postoperative wounds in patients with rectal cancer have impact on long term results: they are independent risk factor for systemic recurrence development and decrease total and cancer specific survival rate.
CLINICAL RESEARCH
In 21.6–70.4% cases surgeons meet technical issues while forming duodenal stump when pathological process is closely located. We know about 200 kinds of duodenal stump closure, but with such a great variety of suturing methods there is no guarantee of safe suturing.
Objective. Improve outcomes in patients with pylorus and gastric outlet cancer.
Materials and Methods. Authors worked out a technique for duodenal stump formation (licence no. 2613940, dated 19.01.2016) that was evaluated in 315 patients in 2014–2017. Patients with gastric cancer diagnosis underwent extended (D2-3) gastrectomy 190 (60.5%) and subtotal distal gastric resection according to Balfour 125 (39.5%).
Results. While manipulating with duodenal stump in 45 (57.7%) patients we respected duodenal bulb to ensure radical surgical intervention. In 63 (80.8%) patients to adjust functional surgical results we performed cholecystectomy. Analysing immediate results we observed no suture insufficiency in duodenal stump, in 4 (5.2%) cases we noticed increased levels of alpha-amylase and mild enlargement of pancreas head while performing abdominal ultrasound examination. Postoperative complications were found in 5 (6.4%) cases: thromboembolism of small pulmonary artery branches – 2 (2.6%), lower lobe pneumonia – 3 (6.4%), postoperative pancreatitis – 1 (1.3%).
Conclusion. Application of monofilament for mechanic closure facilitated usage of this technique during laparoscopy with performing extra corporal knots; it secures anatomical, atraumatic adaptation of suturing tissues. This method for duodenal stump hermetic closure is characterised as a simple and reliable technique. Its usage allowed to achieve radical reduction of suture insufficiency and improve total outcomes in gastric cancer patients.
Background. Study long-term results following endoprosthesis and arthrodesis of an ankle joint.
Material and Methods. During the period from 2006 to 2018, we arthrodesed 102 ankle joint and endoprosthesing with DePyu Mobility implants in patients with arthroses of various etiology. Of operated on patients,there were 16 female patients (61.5%) and 10 (38.5%) male patients, age range was from 19 to 78 years (mean age 50.6 years). The average operative time was 1.6 hours. Average blood loss was 200 ml. Of patients with arthrodesis procedures: 76 (75.5%) – female patients and 26 (25.5%) – male patients, age range varied from 32 to 68 years (mean age was 49 years). The average operative time was 2 hours, and average blood lost was 300 ml.
Results. To compare surgical results we applied AOFAS score defining treatment results according to functional criteria. Of 31 cases with endoprosthesing in 29 (93.5%) we observed sufficient long term results, and in 2 cases (6.5%) – satisfactory. Twenty-five patients (80.6%) were pleased with outcomes of surgery. In 20 patients (64.5%) volume of movement is less than usual, but more comparing to preoperative value. In 3 cases (9.3%) the pain syndrome was also stopped and volume of movements was unchanged and in 3 patients movements were normal (they had no significant ristrictions prior to the operation). In 1 case (3.2%) after endoprosthesing of ankle joint we observed varus deformity at the level of subtalar joint, so we performed correcting subtalar arthrodesis. In 2 patients (6.4%) achieved results were assessed as insufficient due to forming femoroacetabular impingement and pain syndrome. Cases of unstable endoprostheses were not seen. Following ankle joint arthrodesis we observed sufficient long-term results in 78 patients (76.4%), satisfactory results were in 24 (23.5%) patients. And in 24 cases (23.9%) patients required reoperation due to poor results of arthrodesis.
Conclusion. Ankle joint replacement with modern implants allows to achieve sufficient clinical results and it is a hi-tech alternative to arthrodesis procedures.
