Review Meta Analysis Comparative Study
Laparoscopic versus open distal pancreatectomy: a systematic review of comparative studies.
The laparoscopic approach to distal pancreatectomy (DP) for benign and malignant diseases appears to offer advantages and is replacing open surgery in some centers. This review examined the evidence from published data of comparative studies of laparoscopic versus open DP. ⋯ The laparoscopic approach to DP offers advantages over open surgery with lower operative morbidity, higher spleen preservation rate, and shorter hospital stay; these benefits are particularly observed in patients with benign disease and borderline malignancy. The experience with laparoscopic DP for malignant disease remains limited, and long-term follow-up data are required to clearly define this role.

Randomized Controlled Trial Comparative Study
Objective hypoesthesia and pain after transabdominal preperitoneal hernioplasty: a prospective, randomized study comparing tissue adhesive versus spiral tacks.
Irritation of inguinal nerves with laparoscopic hernia repair may cause chronic neuralgia and hypoesthesia. Hypoesthesia in particular is generally not assessed objectively. We objectively investigated hypoesthesia and chronic pain after transabdominal preperitoneal inguinal hernia repair (TAPP) with titanium spiral tacks (STs) compared with tissue adhesive (TA) for mesh fixation. ⋯ Postoperative hypoesthesia depends on the method of mesh fixation during TAPP and is significantly reduced with TA compared with stapling.

The benefits of haptic feedback in laparoscopic surgery training simulators is a topic of debate in the literature. It is hypothesized that novice surgeons may not benefit from the haptic information, especially during the initial phase of learning a new task. Therefore, provision of haptic feedback to novice trainees in the early stage of training may be distracting and detrimental to learning. A controlled experiment was conducted to examine the effect of haptic feedback on the learning curve of a complex laparoscopic suturing and knot-tying task. ⋯ In general, learning with haptic feedback was significantly better than learning without it for a laparoscopic suturing and knot-tying task, but only during the first 5 h of training. Haptic feedback may not be warranted in laparoscopic surgical trainers. The benefits of a shorter time to the first performance plateau and more consistent initial performance should be balanced with the cost of implementing haptic feedback in surgical simulators.

Surgical resection is the mainstay treatment for resectable esophageal cancer. Minimally invasive esophagectomy is performed with increasing frequency and proves to be a safe and effective surgical alternative to the open technique. Minimally invasive esophagectomy using thoracoscopic esophageal mobilization with the patient in prone position seems to offer some advantages with regard to surgeon ergonomics and clinical outcome. ⋯ Minimally invasive esophagectomy is safe and technically feasible. It entails a lower mortality rate and a shorter hospital stay than those reported in most open series. Thoracoscopy with the patient in prone position offers results comparable with those obtained using other minimally invasive techniques regarding the number of procured lymph nodes. This technique shows considerable advantages such as improved surgeon ergonomics, increased operative field exposure, and satisfactory respiratory results.

Laparoscopic cholecystectomy currently is the gold standard technique for gallbladder removal. The use of routine intraoperative cholangiography (IOC) is widely practiced during conventional four-port laparoscopic cholecystectomy (4PLC) to confirm biliary anatomy and allow for immediate management of unexpected choledocholithiasis. Single-incision laparoscopic surgery (SILS) offers a more aesthetic technique for gallbladder removal and has been reported by several groups. However, no series to date have included routine IOC without a separate incision. This study aimed to demonstrate the feasibility of the SILS technique for cholecystectomy with routine IOC (LCIOC) and common bile duct (CBD) exploration as needed via the umbilical port. ⋯ This study represents the largest series to date of single-incision laparoscopic cholecystectomies with routine IOC via the umbilical port and is the first study to demonstrate that the laparoscopic management of choledocholithiasis during SILC is feasible.
