Hand-assisted laparoscopic surgery for a large gastrointestinal stromal tumor of the stomach

We report two cases of large gastrointestinal stromal tumor (GIST) of the stomach that were successfully treated by hand-assisted laparoscopic surgery (HALS). Two patients, a 56-year-old woman and a 60-year-old man, were admitted to our department for the treatment of a large submucosal tumor of the stomach. After gastrointestinal endoscopy, ultrasonography, computed tomography, and magnetic resonance imaging, we suspected that the masses, measuring 7.0 cm and 8.0 cm in diameter, respectively, were GISTs in the stomach. However, preoperatively, we could not rule out the possibility of malignant neoplasms, because they had been bleeding or gradually growing. Hand-assisted laparoscopic wedge resection was safely performed for the diagnosis and treatment of the submucosal tumor of the stomach. The immunohistochemical diagnosis in both patients was GIST of the stomach with intermediate-grade malignancy. HALS may be a good indication for large GISTs of the stomach that are difficult to diagnose preoperatively, whether they are malignant or benign, because it is safe and minimally invasive, promoting rapid recovery.

Single-incision or conventional laparoscopic adjustable gastric banding: A systematic review

Introduction: Single-incision laparoscopic surgery (SILS) in gastric banding (SI-LAGB) has been reported to be a safe and technically feasible procedure among various operating methods. However, there is little evidence with regard to the question whether SI-LAGB has more advantages and should be recommended compared with conventional LAGB (CLAGB). Thus, this study was performed to assess the safety and efficacy of SI-LAGB. Material and methods: A computerized search of the electronic databases PubMed and EMBASE was performed. Data regarding operative parameters, postoperative recovery parameters, follow-up time, percentage of excess weight loss, and postoperative complication were pooled and analyzed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations. Results: Ten comparative studies including 2,073 patients (1,038 patients who received SI-LAGB and 1,035 patients who received CLAGB) were included and analyzed. Compared with CLAGB, a similar weight loss could be obtained using SI-LAGB. The postoperative complications of SI-LAGB were within the acceptable range, but one study reported one perioperative death. SI-LAGB required a longer operative time. Other outcome variables, such as blood loss, days of hospitalization, pain score, and hospitalization costs, were not significantly different between the two groups. Conclusions: SI-LAGB might be a safe and effective alternative to C-LAGB when performed by experienced surgeons, but available data do not allow to give a definitive answer and randomized controlled trials are needed.

Effectiveness and safety of endoscopic resection for gastric GISTs: a systematic review

Aims: To evaluate the effectiveness and safety of endoscopic resection for gastric gastrointestinal stromal tumors (GISTs).

Material and methods: The effectiveness and safety of endoscopic resection were mainly assessed by complete resection rate, postoperative adverse event rate, and recurrence rate. Moreover, a comparison of endoscopic with laparoscopic resection for gastric GISTs was made through weighted mean difference by STATA 12.0 with regard to operation time, blood loss, and length of stay after including patients who underwent endoscopic or laparoscopic resection for gastric GISTs in the comparative studies.

Results: Eleven studies investigating endoscopic resection for GISTs were included. For stromal tumors <2?cm in average diameters the pooled rates of complete resection, postoperative adverse events and recurrence were 0.97, 0.08, and 0.03, respectively. Only five retrospective studies directly compared endoscopic with laparoscopic resection for gastric GISTs with average diameters from 1.1?cm to 3.8?cm, and endoscopic resection had a shorter operation time than laparoscopic resection, but there were no significant differences in intraoperative blood loss, length of stay, postoperative complications, and postoperative recurrence rates between the two approaches.

Conclusions: Endoscopic resection is predominantly tried for gastric GISTs of relatively small size. It seems effective and safe for gastric GISTs <2?cm in average diameter, with relatively short operation times.     

Emphysematous Cholecystitis

Emphysematous cholecystitis is a relatively rare variant of acute cholecystitis with infection by gas-producing organisms. Diagnosis involves the demonstration of gas within the lumen or wall of the gallbladder by ultrasound or CT scan. In contrast to acute cholecystitis, emphysematous cholecystitis occurs more commonly in elderly and diabetic patients, and is frequently associated with perforation and death. We report here a case of a 75-year old man who developed emphysematous cholecystitis.     

Surgical management of pelvic organ prolapse

Pelvic organ prolapse is a common condition which can have a profound effect on health-related quality of life. The lifetime risk of surgery for pelvic organ prolapse for all women is around 10–12%, making prolapse surgery one of the most commonly performed operations of all. Surgery is generally offered only to women to do not respond to conservative measures such as physiotherapy and/or vaginal pessaries. It is very important to ensure excellent clinical governance around the decision-making process for this elective surgical problem, and this may include the use of written information, face to face and telephone consultations, patient reported outcome measures and patient decision aids. This chapter will cover all the different techniques for prolapse surgery including conventional approaches using native tissue, uterus conserving prolapse surgery and surgery for post-hysterectomy vault prolapse. This will also include laparoscopic prolapse surgery. The role of mesh in prolapse surgery will also be discussed and this chapter will cover important topics including patient selection and preparation for prolapse surgery, shared decision making and how best to facilitate this, patient preparation before prolapse surgery and follow-up post operation.     

Immediate Continence Rates in RALRP: A Comparison of Three Techniques

Methods:We retrospectively analyzed the patients who underwent RALRP for localized prostate cancer by a single surgeon in our clinic from January 1, 2009–February 1, 2016. Continence was defined as no leakage or use of a safety pad for minimal leakage. The main outcome measure was continence at postoperative week 1 and months 1, 6, and 12.Results:Between 2009 and 2016, 239 patients underwent RALRP for localized prostate disease. Seventy-four patients underwent a standard approach (group 1), 88 had posterior reconstruction (group 2), and 77 had posterior reconstruction with total anatomic restoration (group 3). After 1 week, 24.3% of the patients in group 1 (18/74), 31.8% in group 2 (28/88), and 45.8% in group 3 (33/72) were continent (P = .02). One month after the surgery, continence rates for groups 1, 2, and 3 were 56.7, 67, and 75%, respectively (0.065). After 6 and 12 months, continence rates for groups 1, 2, and 3 were 72.9 and 87.8%, 81.8 and 89.7%, and 84.7 and 91.6%, respectively (P = .178 and .7484).Conclusion:Anatomic restoration improves continence rates in the early period after RALRP. Even though other parameters were higher in the total restoration group, immediate continence (at 1 week) was significantly better.
