Background This study aimed to compare short- and long-term outcomes after robotic versus laparoscopic approach in patients undergoing curative surgery for rectal cancer. Methods Patients undergoing elective robotic and laparoscopic resection for rectal cancer were included. Perioperative clinical characteristics, postoperative short- and long-term outcomes were compared between groups. Results There were 72 and 44 patients in robotic (RG) and laparoscopic (LG) groups respectively. No differences were detected regarding patients' demographics, histopathologic outcomes, conversion rates and 30-day overall postoperative complication rates. Operative time was longer in the RG (341 ± 111.7 vs. 263 ± 97.5 min, p = 0.001) and length of stay was longer in the LG (4.4 ± 1.9 vs. 6.4 ± 2.9 days, p = 0.001). The 5-year overall and disease-free survival rates were similar (97.1% and 94.9%, p = 0.78; 86.2% and 82.7%, p = 0.72) between the groups. Conclusion This study showed both short and long-term outcomes of a limited number of included patients between the robotic and laparoscopic surgery were similar. However, future studies and randomized trials are necessary to establish these findings.

Background Data regarding the outcomes of pure minimally invasive techniques of radical gastrectomy are scarce. We aimed to compare short-term post-operative outcomes in patients undergoing totally minimally invasive radical gastrectomy with the da Vinci Xi® robotic system versus straight laparoscopy for gastric adenocarcinoma. Methods Between December 2013 and March 2018, robotic and laparoscopic radical gastrectomy performed in two centres were included. Both groups were compared with respect to perioperative short-term outcomes. Results Ninety-four patients were included in the study. Anticoagulant and neoadjuvant chemotherapy use were higher in the robotic group (p = 0.02, p = 0.02). There were conversions in the laparoscopy group whereas no conversions occurred in the robotic group (p = 0.052). Operating time in the robotic group was longer (p = 0.001). The number of harvested lymph nodes in the laparoscopic group was higher (p = 0.047). Conclusion Totally robotic technique with the da Vinci Xi® robotic system provides similar short-term results compared to laparoscopic surgery in radical gastrectomy.

BACKGROUND In this study, we aimed to compare short- and long-term outcomes between laparoscopic totally extraperitoneal (L-TEP) and robotic transabdominal preperitoneal (R-TAPP) inguinal hernia repair. METHODS Patients were classified into two groups: L-TEP and R-TAPP. The groups were case-matched in a 1:1 ratio based on age, gender, and body mass index (BMI). RESULTS Out of 86 patients, 43 patients were matched in each group based on the study criteria. Demographics were comparable between the groups. Operative time was significantly longer for the R-TAPP compared to L-TEP (129.1 ± 47.2 min vs 92.5 ± 28.3 min; P

Background Stoma creation is a common procedure in colorectal surgery. Despite improved surgical techniques, ostomy-related wound complications may prolong the recovery period and impair health-related quality of life. Negative pressure wound therapy (NPWT), autolytic debridement agents, and silver dressings are often used for managing complex wound infection and dehiscence. These applications have the potential to increase patient comfort and accelerate recovery. Case We report our experience in a 66 year old female who had a wound dehiscence involving the ostomy after robotic abdominoperineal resection. Her medical history was significant for a rectovaginal fistula which occurred after a low anterior resection for rectal cancer 5 years ago. Interventions for treatment of the dehiscence were use of NPWT, autolytic debriding agent, and silver dressing. Conclusion Combined use of these interventions for dehiscence of an ostomy can minimize patient discomfort and accelerate wound healing.

Background Introduction of the da Vinci Xi system has facilitated the use of robotics in colorectal surgery. Nevertheless, data on the outcomes of robotic surgery for the treatment of colonic diverticulitis have remained scarce. Methods Patient demographics, clinical characteristics, and perioperative outcomes of the patients undergoing totally robotic with the da Vinci Xi system or laparoscopic surgery for left-sided colonic diverticulitis (LCD) were compared. Results Laparoscopic and robotic groups included 22 and 20 patients, respectively. There were no significant differences between the two groups in terms of patient demographics, clinical characteristics, operative time, and postoperative complications. There were three conversions in the laparoscopy group and no conversion in the robotic group (P = 0.23). Conversion to open surgery was associated with postoperative morbidity (P = 0.02). Conclusion Robotic surgery is an applicable alternative for the treatment of LCD. Robotic approach may potentially lower the risk of operative morbidity by reducing the requirement of conversion.

Background Limited data exist regarding adoption of evolving robotic technology in surgery. This study evaluated trends and the current condition of robotic platforms in surgical specialties and general surgical subspecialties. Methods Between January 2013 and December 2017, all robotic operations performed in Turkey were included. Results In the study period, 13 760 robotic operations were performed at 32 hospitals. The median numbers of general surgical procedures were 43and eight cases per hospital and per general surgeon, respectively. The high-volume general surgeons performed 1734 (81%) of the cases. Forty-five percent and 55% of the general surgical operations were performed with the Xi and S/Si robots, respectively. Conclusion Use of the Xi platform seems to increase caseload in general surgery operations possibly by facilitating robotic colorectal surgery. Targeting the high-volume centres and surgeons for further training and implantation of upcoming robotic technology can be more effective in terms of increasing case volume and improving outcomes.

Polyarteritis nodosa is a rare disorder and a form of systemic vasculitis. A 48 year-old female was admitted to the hospital because menorrhagia and pelvic pain in February 1993. The patient underwent exploratory laparotomy resulting in a total hysterectomy and bilateral salpingo-oophorectomy for myoma of uterus and a right adnexal cystic mass. Histopathologic examination revealed left ovarian periarteritis nodosa. Further investigation and 9 months follow-up failed to show any systemic involvement. To our knowledge the isolated ovarian polyarteritis nodosa is the first case in the literature.
