Background: The search for less traumatic surgical procedures without compromising efficacy and safety, together with the technological advances and greater experience of the teams, led to the development of operative techniques with increasingly smaller incisions, the so-called “minimally invasive surgeries”. Aim: To evaluate the technical aspects and results of single port cholecystectomy. Method: Were analyzed 170 patients between 18-74 years submitted to videolaparoscopic cholecystectomies by single port, regardless of elective or urgent indication, without restriction of patient selection. Results: Among the 170 operations, 158 were exclusively performed by single port, and the conversion rate was 7% (inclusion of other accessory trocars or conversion to multiportal). Conversion to open surgery occurred in three cases (1.76%). The mean surgical time was 67.97 min, showing a marked decrease when was reached close to 50 cases and a stabilization after 100 surgeries. The overall complication rate was 10%, with minor complications such as: incisional pain, hematomas, granulomas, port access hernias (9.41%). Conclusion: Single port cholecystectomy can, after standardization and surgical team training, be a safe surgical procedure associated with a recognized aesthetic advantage.

Background: Pilonidal cysts are a painful condition that primarily affect young adult men. In the literature, numerous operative techniques for resolving pilonidal cysts are described, with variable outcomes. The objective of this study was to compare primarily closed midline incisions managed with or without the use of closed incision negative pressure therapy after pilonidal cyst excision. Methods: Twenty-one patients underwent excision and midline primary closure. Postoperative care composed of closed incisional negative pressure therapy (study group; n = 10) or gauze dressings (control group; n = 11). In both groups, the sutures were partially removed on day 14 and completely removed on day 21. Compared outcomes included the duration of hospitalization, pain on the day of surgical procedure, and on postoperative day 7, and time-to-healing. Results: The median hospital stay was about 9 hours and 23 hours in the study and control groups, respectively ( P < 0.05). The median pain scores on the day of operation were 1.20/10 in the study group and 3.36/10 in the control group ( P < 0.05). On day 7, study group showed median pain score 0.9/10 and control group showed 2.63/10 ( P < 0.05). The mean healing time was 23.8 and 57.9 days in the ciNPT group and gauze group, respectively ( P < 0.05). Conclusion: These outcomes supported the incorporation of closed incision negative pressure therapy into our surgical treatment protocol for pilonidal cysts.
