Comparative Study
Laparoscopic appendectomy and cholecystectomy versus open: a study in 1999 pregnant patients.
When pregnant patients require surgery, whether to perform an operation open or laparoscopic is often debated. We evaluated the impact of laparoscopy for common general surgical problems in pregnancy to determine safety and trends in operative approach over time. ⋯ While fetal events are unknown, LA and LC in pregnant patients demonstrated shorter ORT, LOS, and reduced complications and were performed more frequently over time. Even in perforated cases, laparoscopy appears safe in pregnant patients.

Comparative Study Observational Study
A population-based study comparing laparoscopic and robotic outcomes in colorectal surgery.
Current data addressing the role of robotic surgery for the management of colorectal disease are primarily from single-institution and case-matched comparative studies as well as administrative database analyses. The purpose of this study was to compare minimally invasive surgery outcomes using a large regional protocol-driven database devoted to surgical quality, improvement in patient outcomes, and cost-effectiveness. ⋯ When compared to conventional laparoscopy, the robotic platform is associated with significantly fewer conversions to open for rectal operations, and significantly shorter length of hospital stay for colon operations, without increasing overall postoperative morbidity. These findings and the recent upgrades in minimally invasive technology warrant continued evaluation of the role of the robotic platform in colorectal surgery.

Clinical Trial
Unidirectional barbed sutures as a novel technique for laparoscopic ventral hernia repair.
Incisional hernias remain a significant complication of abdominal surgeries. Primary closure of the hernia defect has been suggested to improve long-term abdominal wall function. However, this can be technically challenging and time consuming. This study describes laparoscopic use of non-absorbable barbed sutures in primary closure of hernia defects in addition to intraperitoneal mesh. ⋯ The barbed suture closure system could be used for rapid and effective primary defect closure in laparoscopic ventral hernia repair in addition to intraperitoneal mesh placement. No significant difference in operating time was detected when compared to the mesh-only approach. Further evidence to support these findings and longer follow-up periods is warranted to evaluate short- and long-term complications.

Comparative Study Observational Study
Biliary stenting is not a prerequisite to endoscopic placement of duodenal covered self-expandable metal stents.
Duodenal covered self-expandable metal stent (cSEMS) can be used in malignant or benign gastroduodenal obstruction. The need for biliary stenting in patients with no concomitant biliary stricture, before duodenal cSEMS placement, remains unknown. The aim of this study was to determine whether cSEMS placement is responsible for biliary obstruction. ⋯ Previous biliary stenting is not required before endoscopic covered duodenal stent placement in patients with no associated biliary obstruction. Prospective studies are needed.

Outcomes for single-incision laparoscopic colectomy surgery in obese patients: a case-matched study.
Single-incision laparoscopic surgery (SILS) is safe and feasible for benign and malignant colorectal diseases. SILS offers several patient-related benefits over multiport laparoscopy. However, its use in obese patients has been limited from concerns of technical difficulty, oncologic compromise, and higher complication and conversion rates. Our objective was to evaluate the feasibility and efficacy of SILS for colectomy in obese patients. ⋯ Single-incision laparoscopic colectomy in obese patients had significantly longer operative times, but comparable conversion rates, oncologic outcomes, lengths of stay, complication, and readmission rates as the non-obese cohorts. In the obese, where higher morbidity rates are typically associated with surgical outcomes, SILS may be the ideal platform to optimize outcomes in colorectal surgery. With additional operative time, the obese can realize the same clinical and quality benefits of minimally invasive surgery as the non-obese.
