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.

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.

In selected patients with N0 rectal cancer, endoluminal loco-regional resection (ELRR) by transanal endoscopic microsurgery (TEM) may be an alternative treatment option to laparoscopic total mesorectal excision (LTME). Aim of this study is to evaluate the short- and medium-term quality of life (QoL) from a retrospective analysis of prospectively collected data in patients with iT2-iT3 N0-N+ rectal cancer, who underwent ELRR by TEM or LTME after neoadjuvant radio-chemotherapy (n-RCT). ⋯ Based on the present series, in selected patients, earlier restoration of patients' functions is observed after ELRR by TEM than after LTME.

Even though more and more cases of laparoscopic central pancreatectomy (LCP) are reported (Machado et al. in Surg Laparosc Endosc Percutan Tech 23(6):486-490, 2013; Hong et al. in World J Surg Oncol 10:223, 2012; Gonzalez et al. in JOP 14(3):273-276, 2013, Zhang et al. in J Laparoendosc Adv Surg Tech A 23(11):912-918, 2013; Sucandy et al. in N Am J Med Sci 2(9):438-441, 2010; Sa Cunha et al. in Surgery 142(3):405-409, 2007), the management for pancreatic stumps remains the most technically challenging part which is the same as in pancreatoduodenectomy (PD), making it the bottleneck for laparoscopic pancreatic surgery. In open surgery, various pancreatic reconstruction techniques designed for either pancreaticojejunostomy (PJ) or pancreaticogastrostomy (PG) have been attempted to reduce the postoperative pancreatic fistula (POPF), including the binding anastomosis, invented by our team, i.e., binding PG (BPG) and binding PJ, which have been proved to be effective to reduce the POPF (Hong et al. 2012; Peng et al. in Ann Surg 245(5):692-698, 2007; Peng et al. in Updates Surg 63(2):69-74, 2011). However, despite of this, few reports are seen addressing such technique for laparoscopic surgery even though laparoscopic pancreatic surgery is more performed. After a previous successful laparoscopic BPG in a case of laparoscopic CP (LCP; Hong et al. 2012) and more than 50 cases of open PD and CP (Peng et al. 2011), we further performed laparoscopic BPG in 10 consecutive cases of LCP with satisfactory outcomes. ⋯ LCP with BPG is feasible and safe; the advantages lie in its minimal invasiveness, the efficacy for avoiding PF, and the preservation of the pancreatic endocrine and exocrine function insufficiency, making it an ideal procedure for the benign or low-malignant lesions at the pancreatic neck.

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.
