INTRODUCTIONLaparoscopic cholecystectomy is currently the gold standard for removal of symptomatic gallbladders. The push in recent years toward reducing the number of ports required to perform this surgery has led to the development of single-incision laparoscopic cholecystectomy (SILC). We report our early experience with SILC and assess its feasibility and safety.
METHODSA prospective study was conducted of the first 100 patients who presented with complaints of biliary colic and underwent laparoscopic cholecystectomy via the single-port technique at our institution. SILC was performed via a single-port device such as a flexible umbilical port that could accommodate up to three surgical instruments. The port was inserted into a transumbilical incision around 15-20 mm long. Data on operative details and postoperative outcomes were collected and evaluated.
RESULTSThe mean operation time was 67.8 minutes. Six patients needed conversion, requiring extra 5-mm ports to complete the surgery. No serious intraoperative complications, such as bile duct injury or bile leakage, were encountered. Cosmesis from the scar hidden within the umbilical fold was excellent.
CONCLUSIONOur initial results of single-port laparoscopic cholecystectomy are promising, with no complications being seen in this early series. However, the drawbacks include the higher cost of equipment and a steeper learning curve. Further evaluation is required to assess the risks and benefits of this approach when compared with conventional laparoscopic cholecystectomy.

Purpose:
Endoscopic total mastectomy (ETM) is predominantly performed with reconstruction using prostheses, lipofilling, omental flaps, latissimus dorsi flaps, or a combination of these techniques. Common approaches include minimal incisions, e.g., periareolar, inframammary, axillary, or mid-axillary line, which limit the technical ability to perform autologous flap insets and microvascular anastomoses, as such the ETM with free abdominal-based perforator flap reconstruction has not been robustly explored.
Methods:
We studied female patients with breast cancer who underwent ETM and abdominal-based flap reconstruction. Clinical-radiological-pathological characteristics, surgery, complications, recurrence rates, and aesthetic outcomes were reviewed.
Results:
Twelve patients underwent ETM with abdominal-based flap reconstruction. The mean age was 53.4 years (range 36–65). Of the patients, 33.3% were surgically treated for stage I, 58.4% for stage II, and 8.3% for stage III cancer. Mean tumor size was 35.4 mm (range 1–67). Mean specimen weight was 458.75 g (range 242–800). Of the patients, 92.3% successfully received endoscopic nipple-sparing mastectomy and 7.7% underwent intraoperative conversion to skin-sparing mastectomy after carcinoma was reported on frozen section of the nipple base. Mean operative time for ETM was 139 minutes (92–198), and the average ischemic time was 37.3 minutes (range 22–50). Fifty percent of patients underwent deep inferior epigastric perforator, 33.4% underwent MS-2 transverse rectus abdominis musculocutaneous (TRAM), 8.3% underwent MS-1 TRAM, and 8.3% underwent pedicled TRAM flap reconstruction. No cases required re-exploration, no flap failure occurred, margins were clear, and no skin or nippleareolar complex ischemiaecrosis developed. In the aesthetic outcome evaluation, 16.7% were excellent, 75% good, 8.3% fair, and none were unsatisfactory. No recurrences were observed.
Conclusion
ETM through a minimal-access inferior mammary or mid-axillary line approach, followed by immediate pedicled TRAM or free abdominal-based perforator flap reconstruction, can be a safe means of achieving an “aesthetically scarless” mastectomy and reconstruction through minimal incisions.
