Randomized Controlled Trial Comparative Study
Superiority of preemptive analgesia with intraperitoneal instillation of bupivacaine before rather than after the creation of pneumoperitoneum for laparoscopic cholecystectomy: a randomized, double-blind, placebo-controlled study.
This study aimed to evaluate the optimal timing of preemptive analgesia with bupivacaine peritoneal instillation in a prospective, randomized, double-blind, placebo-controlled trial. ⋯ Preemptive analgesia with bupivacaine peritoneal instillation is much more effective for pain relief if used before creation of pneumoperitoneum. Although the effect of bupivacaine peritoneal instillation is also noticeable when used after creation of pneumoperitoneum, it confers significantly lower benefits.

Comparative Study Clinical Trial
Laparoscopic versus open ventral hernia mesh repair: a prospective study.
An incisional hernia develops in 3% to 13% of laparotomy incisions, with primary suture repair of ventral hernias yielding unsatisfactory results. The introduction of a prosthetic mesh to ensure abdominal wall strength without tension has decreased the recurrence rate, but open repair requires significant soft tissue dissection in tissues that are already of poor quality as well as flap creation, increasing complication rates and affecting the recurrence rate. A minimally invasive approach was applied to the repair pf ventral hernias, with the expectation of earlier recovery, fewer postoperative complications, and decreased recurrence rates. This prospective study was performed to objectively analyze and compare the outcomes after open and laparoscopic ventral hernia repair. ⋯ The findings demonstrate that laparoscopic ventral hernia repair in our experience was safe and resulted in shorter operative time, fewer complications, shorter hospital stays, and less recurrence. Hence, it should be considered as the procedure of choice for ventral hernia repair.

Comparative Study Clinical Trial
Can laparoscopically assisted sigmoid resection provide uncomplicated management even in cases of complicated diverticulitis?
Laparoscopically assisted sigmoid resection has become an accepted method for treating uncomplicated diverticulitis. This prospective study aimed to compare the results of laparoscopic sigmoid resection for uncomplicated and complicated sigmoid diverticular disease used to check the indication for the complicated stages of diverticulitis. ⋯ Laparoscopic sigmoid resection can be performed for patients who have complicated diverticulitis without significantly increasing their overall morbidity. This group of patients could benefit from the advantages of the minimally invasive procedure despite a longer operating time and a higher conversion rate.

Laparoscopy still is not universally accepted as an alternative approach for pancreatoduodenectomy. This study aimed to assess the feasibility and safety of laparoscopic pancreatoduodenectomy for benign and malignant lesions of the pancreas, and to examine whether this procedure obtains adequate margins and follows oncologic principles. To the best of the authors' knowledge, their series of laparoscopic pancreatoduodenectomies is the largest reported to date. ⋯ Laparoscopic pancreatoduodenectomy for selected cases of benign and malignant lesions performed by highly skilled laparoscopic surgeons is feasible and safe. This method can obtain adequate margins and follow oncological principles. Larger series and longer follow-up periods are needed to establish the current results.

Percutaneous abscess drainage guided by computed tomography scan is considered the initial step in the management of patients presenting with Hinchey II diverticulitis. The rationale behind this approach is to manage the septic complication conservatively and to follow this later using elective sigmoidectomy with primary anastomosis. ⋯ Drainage of Hinchey II diverticulitis guided by computed scan was successful in two-thirds of the cases, and 35% of the patients eventually underwent a safe elective sigmoid resection with primary anastomosis. By contrast, failure of percutaneous abscess drainage to control sepsis is associated with a high mortality rate when an emergency resection is performed. The current results demonstrate that percutaneous abscess drainage is an effective initial therapeutic approach for patients with Hinchey II diverticulitis, and that emergency surgery should be avoided whenever possible.
