Selective approach to arterial ligation in radical sigmoid colon cancer surgery with D3 lymph node dissection: A multicenter comparative study.

Objectives: Radical surgery for sigmoid colon cancer is commonly performed with complete mesocolic excision (CME) and apical lymph node dissection, reached by central vascular ligation (CVL) of the inferior mesenteric artery (IMA) and associated extended left colon resection. However, IMA branches can be ligated selectively according to tumor location with D3 lymph node dissection (LND), economic segmental colon resection and tumorspecific mesocolon excision (TSME) if IMA is skeletonized. This study aimed to compare left hemicolectomy with CME and CVL and segmental colon resection with selective vascular ligation (SVL) and D3 LND.

Significant augmentation of the incidence of duodenal neuroendocrine tumors duodenum has been observed in recent decades. There are 5 histological types of these tumors: gastrinoma (50-60%), somatostatin-producing tumor (15%), inactive serotonin-containing tumors (20%), poorly differentiated neuroendocrine carcinoma (<3%) and gangliocytic paraganglioma (<2%). The majority of tumors are localized within the bulb and postbulbar part of duodenum, 20% are found in periampular area.

Prevalence, risk factors of primary pancreatic tuberculosis, clinical symptoms and data of instrumental and laboratory diagnosis are reviewed in the article. The authors emphasized the peculiarities of differential diagnosis with pancreatic malignancies and advisability of the most informative methods - endoscopy and fine-needle aspiration procedure.

[Current state of the problem of allotransplantation of Langerhans cells (achievements and prospects)].

Literature data devoted to transplantation of Langerhans cells have been analyzed. The main stages, indications, dissection of islets, immunosuppressive therapy, complications and data of the latest clinical trials were discussed.

[Problem of decision-making in surgery].

Decision-making process is often complex, responsible and not always reflected in surgical protocol. Some surgeons usually prefer standard finishing of procedure; others talk about individual approach but they have some preferences; the third ones analyze all possible perioperative factors (pre- and intraoperative data) and seek to justify differentiated approach. Some aspects of these processes are discussed in this report.

[The causes of recurrent ulcerative gastroduodenal bleeding].

Aim: To explore microcirculatory changes within the first 48 hours after admission, to compare them with clinical manifestations of bleeding and to define the dependence of recurrent bleeding from the therapy.

Material And Methods: The study included 108 patients with ulcerative gastroduodenal bleeding who were treated at the Clinical Hospital #71 for the period 2012-2014. There were 80 (74.

[Perforated peptic ulcer closure: laparoscopic or open?].

Aim: To compare laparoscopic and open closure of perforated peptic ulcer (PPU).

Material And Methods: The study included 153 patients who underwent PPU suturing. 78 patients underwent laparoscopic closure (laparoscopic group) and open suturing via upper midline laparotomy was performed in 75 cases (open group).

[Single-port laparoscopic cholecystectomy: advantages and disadvantages].

Aim: To analyze the outcomes of single-port laparoscopic cholecystectomy.

Material And Methods: Early and long-term postoperative period has been analyzed in 240 patients who underwent laparoscopic cholecystectomy (LCE) including 120 cases of single-port technique and 120 cases of four-port technique. Both groups were compared in surgical time, pain syndrome severity (visual analog scale), need for analgesics, postoperative complications, hospital-stay, daily activity recovery and return to physical work, patients' satisfaction of surgical results and their aesthetic effect.

[Open alloplasty of postoperative ventral hernias].

Early and long-term results of the open ventral postoperative hernia alloplasty in 118 patients have been analyzed. The onlay and sublay techniques of the hernioplasty have been employed. The frequency of complications, local status and quality of life were studied a year after the operation.

Diagnosis and treatment of stomach ulcer associated with helicoid-bacterial infection and with hemorrhage are discussed in the paper. The many-year observations show that the risk of relapsing hemorrhage is high in patients with the above diagnosis.
