Esophageal perforation constitutes a potentially life-threatening condition, and this study aimed to evaluate the indications and outcome for the different treatment modalities.

Transoral endoscopic thyroidectomy via vestibular approach (TOETVA) is currently considered the most promisingly scarless approach to the thyroid and has gained more acceptance.

Pulmonary hydatid cyst is a preventable parasitary disease with high prevalence in low-medium income countries. Thoracoscopic approach is seen in the literature as small-case groups and multiple-port incisions are observed in these studies. Unlike other thoracoscopic approaches for the surgical treatment, we describe the single-port technique for the first time in our study. We attempt to compare the clinical outcomes and preliminary results of patients with pulmonary hydatid cyst treated with either minimally invasive or thoracotomy.

In contrast to colonic tattooing, data on dye-marking before gastric operations are scarce. A simple method of gastric tattooing before sleeve gastrectomy (SG) is presented. SG, under tattoo guidance has never been reported. Submucosa of the lesion is injected with 1 to 2 mL of carbon particles (Spot, PA) 24 hours before SG. At surgery, serosal dye stain is identified and stapling achieved with care to remove all dye-stained segment. Dye spread on the serosal surface differed significantly. However, as all the dye-stained segments were avoidable during stapling, 2 neuroendocrine tumors, 2 leiomyomas, and 1 benign ulcer were resected with clear histologic margins. The method presented herein may decrease the need for operative gastroscopy, mucosal resection, or laparoscopic gastrotomy in a number of patients. Because of the problem of the dye spreading, its utilization may be inappropriate in lesions that are closer to the minor curvature and incisura angularis in particular.

Percutaneous cholecystostomy (PC) is an alternative to cholecystectomy for acute calculous cholecystitis (ACC) in patients with high mortality risk, but the catheters' and patients' management remains unclear. This study aimed to determine outcomes after PC and to define surgical strategy.

Central pancreatectomy (CP) has been used sparingly because the spectrum of indications is quite narrow. The author has modified the procedure of CP in such a way to avoid distal pancreatic segment drainage, in addition to reserving the patient euo-insulinemic.

Hand-assisted laparoscopic colectomy (HALC) and laparoscopic-assisted colectomy (LAC) have been shown to have comparable short-term outcomes while there are limited data regarding costs. The aim of our study was to compare the short-term outcomes and costs of HALC and LAC.

Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide. Evolution of laparoscopic techniques helps to a great extent in facilitating and replacing the conventional surgical maneuvers. This article describes the novel use of narrow band imaging (NBI) in laparoscopic radiofrequency ablation (LRFA) of exophytic HCC to ensure its adequate ablation. In total, 11 patients with proven HCC were recruited to perform LRFA; NBI were applied during and after completion of ablation session, with NBI, the exophytic HCC appears dark green or blue in color and after start of LRFA; the tumor capsule turned into red color denoting hemoglobin coagulation and vascular damage; in 5 cases and after completion of ablation; the tumor capsule was still dark green or blue denting viability which necessitates needle repositioning and ablation continuation. NBI helps to a great extent in confirmation of successful ablation of exophytic HCC.

In this study, perioperative and short-term postoperative results of totally robotic versus totally laparoscopic rectal resections for cancer were investigated in a comparative manner by considering risk factors including obesity, male sex, and neoadjuvant treatment. In addition to overall comparison, the impact of sex, obesity (body mass index ≥30 kg/m), and neoadjuvant treatment was assessed in patients who had a total mesorectal excision (TME). Operative time was longer in the robotic group (P<0.001). In obese patients who underwent TME, the mean length of hospital stay was shorter (7±2 vs. 9±4 d, P=0.01), and the mean number of retrieved lymph nodes was higher (30±19 vs. 23±10, P=0.02) in the robotic group. Totally robotic and totally laparoscopic surgery appears to be providing similar outcomes in patients undergoing rectal resections for cancer. Selective use of a robot may have a role for improving postoperative outcomes in some challenging cases including obese patients undergoing TME.
