BACKGROUNDSurgical treatment has become the standard treatment for nontraumatic diseases of the spleen. This meta-analysis compared the relative merits of laparoscopic splenectomy (LS) with open splenectomy (OS) for nontraumatic splenic diseases.

METHODSA literature search was performed to identify studies comparing perioperative outcomes in patients who underwent LS or OS for nontraumatic diseases. Pooled odds ratios (ORs) and weighted mean differences (WMD) with 95% confidence intervals (CIs) were calculated using a fixed- or random-effects model.

RESULTSThirty-five studies matched the selection criteria. Of the 7 269 patients included 3 981 underwent LS and 3 288 underwent OS for nontraumatic diseases. OS was associated with shorter operation time (WMD = 42.65, 95% CI: 25.58-59.73), whereas LS was associated with reduced operative blood loss (WMD = -133.95, 95% CI: -229.02 to -38.88), need for blood transfusion requirement (OR = 0.53, 95% CI: 0.39-0.72), overall postoperative morbidity rate (OR = 0.44, 95% CI: 0.38-0.51), postoperative mortality rate (OR = 0.38, 95% CI: 0.24-0.59), and length of hospital stay (WMD = -2.73, 95% CI: -3.34 to -2.12).

CONCLUSIONSLS is superior to OS for nontraumatic diseases, with reduced operative blood loss, need for blood transfusion, postoperative morbidity and mortality rates, and length of hospital stay, although OS is associated with reduced operation time. LS may be a good alternative to OS for patients with nontraumatic splenic diseases.

Background:Laparoscopic total gastrectomy (LTG) is increasingly performed in patients with gastric cancer. However, the usage of intracorporeal esophagojejunostomy (IEJ) following LTG is limited, as the safety and efficacy remain unclear. The present meta-analysis aimed to evaluate the feasibility and safety of IEJ following LTG.

Methods:Studies published from January 1994 to January 2017 comparing the outcomes of IEJ and extracorporeal esophagojejunostomy (EEJ) following LTG were reviewed and collected from the PubMed, EBSCO, Cochrane Library, Embase, and China National Knowledge Internet (CNKI). Operative results, postoperative recovery, and postoperative complications were compared and analyzed. The weighted mean difference (WMD) and odds ratio (OR) with a 95% confidence interval (CI) were calculated using the Review Manager 5.3.

Results:Seven nonrandomized studies with 785 patients were included. Compared with EEJ, IEJ has less blood loss (WMD: -13.52 ml; 95% CI: -24.82--2.22; P = 0.02), earlier time to first oral intake (WMD: -0.49 day; 95% CI: -0.83--0.14; P < 0.01), and shorter length of hospitalization (WMD: -0.62 day; 95% CI: -1.08--0.16; P < 0.01). There was no significant difference between IEJ and EEJ regarding the operation time, anastomotic time, number of retrieved lymph nodes, time to first flatus, anastomosis leakage rate, anastomosis stenosis rate, and proximal resections (all P > 0.05).

ConclusionsCompared with EEJ, IEJ has better cosmesis, milder surgical trauma, and a faster postoperative recovery. IEJ can be performed as safely as EEJ. IEJ should be encouraged to surgeons with sufficient expertise.

In recent years, laparoscopic gastrectomy has developed rapidly for both early and advanced gastric cancer. Most studies showed that the operative complication rate is comparable between laparoscopic and open surgery. The common complications related to laparoscopic gastrectomy are anastomotic leakage, stenosis, intra-abdominal bleeding, pancreatic leakage, bowel obstruction, etc. This article provides insights into the reasons, classification, management, and prevention of the complications related to laparoscopic gastrectomy.

Either tacrine (THA) with succinylcholine or alcuronium was used on a randomized basis for laparoscopic procedures in twenty young females. The technique using THA with succinylcholine was found to be more suitable and predictable for this procedure and gave a smoother anaesthetic course, brighter recovery and minimal postoperative complications.

BACKGROUNDSome patients with exophytic renal masses less than 4 cm and suboptimal renal function, or a solitary kidney and bilateral renal tumors are considered for laparoscopic partial nephrectomy (LPN), which is feasible for early-stage renal tumors, although it is still considered technically difficult and time consuming. Shortening the time of the operation and renal warm ischemia are required urgently. In this study, we report our initial experiences of LPN, especially with some improved surgical techniques.

METHODSBetween July 2005 and October 2009, 74 patients with T(1a) renal tumor were treated by LPN, 39 using transperitoneal approach and 35 using retroperitoneal approach. In all cases, the tumor was removed with a margin of 0.5 cm. We compared glomerular filtration rate (GFR) preoperatively and postoperatively, and renal warm ischemia time between traditional ligature and Hem-o-lok methods.

RESULTSAll operations were completed successfully, and there was no conversion to open surgery. Mean operation time was 76 minutes (range, 68 - 120), mean time of renal warm ischemia was 23 minutes (range, 15 - 32), and mean blood loss was 65 ml (range, 40 - 300). No hemorrhage or urine leak was observed in two cases with the collecting system sewn. Thirteen cases used Hem-o-lok to clamp the suture instead of traditional ligature, and mean time of renal warm ischemia was (16.5 ± 2.3) minutes (range, 12 - 18). Mean postoperative hospital stay was 6.3 days (range, 5 - 12). Sixty-seven cases had renal clear cell carcinoma, six papillary renal cell carcinoma, and one renal collecting duct carcinoma. All the tumor margin specimens were negative. The mean follow-up was 30.6 months (range, 3 - 51), and no recurrence or metastasis was observed.

CONCLUSIONSLPN for pT(1) stage renal tumor was safe and feasible. Hem-o-lok instead of traditional ligature to clamp the suture when sewing the renal wound could shorten the warm ischemia time.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) has become the gold standard operation for morbid obesity, because effects of LRYGB are quick and lasting. However, there are many potential risks due to the operative complexity and long learning curve. There are early and late complications after LRYGB. If the complications are not diagnosed and treated in time and correctly, serious results even death, may occur. Mortality after LRYGB is 0.87%. It is important for the continous and healthy development of LRYGB that postoperative complications can be diagnosed and managed in time and effectively.

OBJECTIVETo compare the clinical characteristics of three subcategories of laparoscopic hysterectomy: total laparoscopic hysterectomy (TLH) and two subcategories of laparoscopic-assisted vaginal hysterectomy (LAVH): LAVHs and LAVHb.

METHODSWe retrospectively analyzed the clinical data of 393 patients underwent laparoscopic hysterectomy, including TLH (n=178), LAVHa (n=177), and LAVHb (n=38), in our hospital from September 2002 to September 2005.

RESULTSMyoma and adenomyosis of uterus were the most common diseases in this study, accounting for 66.9%, 38.4%, and 52.6% in TLH group, LAVHa group, and LAVHb group, respectively. The mean surgery duration and blood loss were not significantly different between TLH group and LAVHa group (P > 0.05), but were significantly less in TLH group than in LAVHb group (P < 0.05). The bulk of uterus in TLH group was significantly bigger than in other two groups (P < 0.05). The incidence of major complications in the TLH group (9. 0%) was lower than in LAVHa group (14.1%) and in LAVHb group (18.4%), but without statistical significance. Conclusion Compared with LAVH, TLH is feasible to deal with bigger uterus with less blood loss and shorter surgery duration and without more frequent complications.

OBJECTIVE: The aim of this paper was to demonstrate the techiniqes of single-port laparoscopic transperitoneal infrarenal paraaortic lymphadenectomy as part of surgical staging procedure in case of early ovarian cancer and high grade endometrial cancer. METHODS: After left upper traction of rectosigmoid, a peritoneal incision was made caudad to inferior mesenteric artery. Rectosigmoid was mobilized, and then the avascular space of the lateral rectal portion was found by using upward traction of rectosigmoid mesentery. Inframesenteric nodes were removed without injury to the ureter and the left common iliac nodes were easily removed due to the upward traction of the rectosigmoid. The superior hypogastric plexus was found overlying the aorta and sacral promontory, and presacral nodes were removed at subaortic area. Peritoneal traction suture to right abdomen was needed for right para-aortic lymphadenectomy. After right lower para-aortic node dissection, operator was situated between the patient's legs. After upper traction of the small bowel, left upper para-aortic nodes were removed. To prevent chylous ascites, we used hemolock or Ligasure application (ValleyLab Inc.) to upper part of infrarenal and aortocaval nodes. RESULTS: Single-port laparoscopic transperitoneal infrarenal para-aortic lymphadenectomy was performed without serious perioperative complications. CONCLUSION: Even though the technique of single-port surgery is still a difficult operation, the quality of single-port laparoscopic transperitoneal infrarenal para-aortic node dissection is excellent, especially mean number of para-aortic nodes. In cases of staging procedures for ovary and endometrial cancer, single-port transperitoneal para-aortic lymphadenectomy is acceptable as an oncologic procedure.

Parastomal hernia is a common complication after abdominal ostomy. Although the European Hernia Society guidelines recommend surgical treatment for parastomal hernia, there is still no "gold standard" procedure. The exploration and practice of parastomal hernia repair surgery has been carried out for many years, from the earlier hernia ring suture and stoma relocation repair, to the reinforcement of meshes (such as the Keyhole repair technique and the Sugarbaker repair technique) and the application of laparoscopic technique, and then to the combination of various methods. The intervention of single-port laparoscopic technique and robot-assisted surgery, the prevention of parastomal hernia, the specialization of treatment, multidisciplinary cooperation, and the improvement of diagnostic methods will all provide more optimal solutions for stoma patients. This article will review and summarize the development process and evaluation of parastomal hernia surgical techniques.
