Standing hand-assisted laparoscopic ovariohysterectomy to treat chronic pyometra in a mare.

OBJECTIVE: To describe a standing hand-assisted laparoscopic ovariohysterectomy in a mare. ANIMAL: A 15-year-old maiden Oldenburg mare. CLINICAL PRESENTATION, PROGRESSION, AND PROCEDURES: The mare was presented for evaluation of bucking under saddle and uncharacteristic aggressive behavior. Evaluation of a 24-hour video of the mare in a stall showed behavior consistent with caudal visceral abdominal discomfort. Reproductive evaluation revealed a pyometra secondary to complete transluminal cervical adhesions. The mare was initially managed medically with disruption of the adhesions and uterine lavage, but the adhesions reformed within 6 weeks and could not be manually disrupted. TREATMENT AND OUTCOME: To eliminate the recurrence of pyometra, the mare underwent standing hand-assisted laparoscopic ovariohysterectomy through bilateral flank incisions. The only complication was a seroma at 1 flank incision that resolved after drainage. CLINICAL RELEVANCE: Complete ovariohysterectomy in the mare is a challenging procedure and has previously been performed under general anesthesia. This is the first report of the procedure being performed completely in the standing mare without inversion of the uterus through the cervix.

Hand-assisted laparoscopic donor nephrectomy: 1864 cases in 15 years of experience.

BACKGROUND: To evaluate hand-assisted laparoscopic donor nephrectomy (HALDN) in terms of intraoperative and postoperative results. METHODS: After institutional review board approval was obtained, a total of 1864 HALDN operations performed between March 2007 and January 2022 were retrospectively analyzed. Age, sex, body mass index (BMI), status of smoking and presence of previous abdominal surgery, laterality, operative time, transfusion requirement, port counts, length of extraction incision, time until mobilization, time until oral intake, donor serum creatinine levels before and one week after the surgery, length of postoperative hospital stay, intraoperative complications, and postoperative recovery and complications were recorded and statistically analyzed. Multiple renal arteries, BMI, right nephrectomy and male sex were also separately evaluated as risk factors for complications and operative time. RESULTS: A total of 825 (44.26%) male and 1039 (55.74%) female patients were enrolled in the study. The mean age of the patients was 45.79 ± 12.88 years. There were a total of 143 complications (7.67% of the total 1864 cases) consisting of 68 (3.65%) intraoperative and 75 (4.02%) postoperative complications. Open conversion was necessary for 10 patients (0.53%) to manage intraoperative complications. Reoperation was needed for 1 patient due to bleeding 6 h after the operation. Multiple renal arteries were a risk factor for intraoperative complications and prolonged operative time. Right nephrectomy and male sex were also related with longer operative times. DISCUSSION: HALDN is a safe procedure associated with low complication rates.

Hand port-site infection after hand-assisted laparoscopic donor nephrectomy for living-donor kidney transplantation: a retrospective cohort study.

Background: Hand-assisted laparoscopic donor nephrectomy (HALDN) is widely performed to minimize burden on living kidney donors. However, hand port-site infections after HALDN may occur. This study aimed to assess the impact of donor characteristics including preoperative comorbidities and operative factors on hand port-site infection after HALDN. Methods: In this single-center, retrospective cohort study, 1,260 consecutive HALDNs for living-donor kidney transplantation performed between January 2008 and December 2021 were evaluated. All living donors met the living kidney donor guidelines in Japan. Hand port-site infections were identified in 88 HALDN cases (7.0%). To investigate risk factors for hand port-site infection, donor characteristics including preoperative comorbidities such as hypertension, glucose intolerance, dyslipidemia, obesity, and operative factors such as operative duration, blood loss, preoperative antibiotic prophylaxis, and prophylactic subcutaneous suction drain placement at the hand port-site were analyzed using logistic regression analysis. Results: In the multivariate analysis, significant differences were identified regarding sex (P = 0.021; odds ratio [OR], 1.971; 95% confidence interval [CI], 1.108-3.507), preoperative antibiotic prophylaxis (P < 0.001; OR, 0.037; 95% CI [0.011-0.127]), and prophylactic subcutaneous suction drain placement at the hand port-site (P = 0.041; OR, 2.005; 95% CI [1.029-3.907]). However, a significant difference was not identified regarding glucose intolerance (P = 0.572; OR, 1.148; 95% CI [0.711-1.856]). Preoperative comorbidities may not cause hand port-site infections within the donors who meet the living kidney donor guidelines. Preoperative antibiotic prophylaxis is crucial in preventing hand port-site infection, whereas prophylactic subcutaneous suction drain placement may increase the risk of hand port-site infection.

Hand-Assisted Laparoscopic Splenectomy with Temporary Splenic Artery Occlusion in Pediatric Patients: The Experience in a Chinese Tertiary Children's Hospital.

Background: The hand-assisted laparoscopic splenectomy (HALS) approach overcomes the difficulties experienced with conventional laparoscopic splenectomy (LS) with added advantages. In this study, we compared the HALS technique with standard LS based on the feasibility and intermediate postoperative outcomes in pediatric patients. Methods: We retrospectively investigated pediatric patients who underwent HALS or LS from October 2013 to May 2021 at the Children's Hospital, Chongqing Medical University. Potential parameters related to HALS or LS were explored, and the intermediate-term clinical outcomes were compared between the two groups. The quality of life and splenic regrowth data were followed up routinely for 12 months after the operation. Results: In total, 39 patients underwent splenectomy (11 for HALS and 28 for LS) and were eligible for this research. Patients who underwent HALS had a greater proportion of focal benign splenic lesions (P < .001) and partial splenectomy (P < .001). The HALS operative time was reduced compared with LS (P = .032). No operation conversion was noted in the HALS group, whereas 4 (14.3%) cases were converted to an open operation (P = .249). For partial splenectomies, favorable outcomes with HALS, including short operative time (P = .001) and reduced blood loss (P = .014), were noted compared with LS. No postoperative mortality was observed. During the follow-up period, a good quality of life and splenic regrowth were noted for most of the patients. Conclusions: Although another incision is necessary, HALS confers the advantages of a minimally invasive technique to manage the fragile spleen, especially in pediatric patients requiring partial splenectomy.

Complications After Hand-Assisted Laparoscopic Living Donor Nephrectomy.

OBJECTIVE: To study the complications of hand-assisted laparoscopic living donor nephrectomy (HALLDN) with an emphasis on complications occurring early after hospital discharge up to 120 days after surgery. PATIENTS AND METHODS: We retrospectively categorized complications using the Clavien-Dindo classification in 3002 HALLDNs performed at 1 center from January 1, 2000, through December 31, 2019. In addition to overall summaries, modeling was used to identify correlates of complications before and after living donation. RESULTS: Of these donors, 87% were White, 59% were female, the mean age was 45 years (range, 18-77 years), 30.3% had a body mass index of at least 30, and 36.3% had previous abdominopelvic surgery. There were no deaths related to the surgery. The incidence of major complications (intraoperative complications plus Clavien-Dindo grade ≥III postoperatively) was 2.5% (n=74). The overall complication rate was 12.4% (n=371), including 15 intraoperative, 76 postoperative before discharge, and 280 after discharge to 120 days. Reoperation was required in 1.8% of patients (n=54), and all but 1 of these were incision-related problems. Seventy-six percent of all complications occurred after discharge, including 85% of the reoperations. For major complications, no risk factor was found. Risk factors for any complication included paramedian incision (hazard ratio [HR], 2.54; 95% CI, 1.49 to 4.34; P<.001); a history of abdominopelvic surgery (HR, 1.37; 95% CI, 1.07 to 1.76; P=.01), male sex (HR, 1.37; 95% CI, 1.07 to 1.76; P=.01), non-White race (HR, 1.40; 95% CI, 1.05 to 1.88; P=.02), and early era of the experience. CONCLUSION: Most major complications of HALLDN occur after discharge, suggesting that close follow-up is warranted and that the current literature may underestimate the true incidence.

Risk factors of unplanned intraoperative conversion to hand-assisted laparoscopic surgery or open surgery in laparoscopic liver resection.

BACKGROUND: Laparoscopic liver resection (LLR) is possible in many patients, but pure LLR is sometimes difficult to complete, and unplanned intraoperative hand-assisted laparoscopic surgery (HALS) or open conversion is sometimes necessary. However, appropriate indications and timing for conversion are unclear. This study aimed to clarify the indications for HALS and open conversion from pure LLR. METHODS: We collected data from 208 patients who underwent LLR from January 2010 to February 2021 in our department. We retrospectively examined these data between cases of unplanned intraoperative HALS conversion, open conversion, and pure LLR, and clarified risk factors and indications for HALS or open conversion. RESULTS: There were 191 pure LLRs, nine HALS conversions, and eight open conversions. In the HALS conversion group versus pure LLR group, body mass index (BMI) (27.0 vs. 23.7 kg/m2, p = 0.047), proportions of patients with history of upper abdominal surgery (78% vs. 33%; p = 0.006), repeat hepatectomy (56% vs. 15%; p = 0.002), S7 or S8 tumor location (67% vs. 35%; p = 0.049), and difficulty score (DS) ≥ 7 (56% vs. 19%; p = 0.008) were significantly higher, and surgical time (339 vs. 239 min; p = 0.031) was significantly longer. However, postoperative states were not significantly different between the two groups. The BMI cutoff value for risk of unplanned intraoperative conversion determined by receiver operating characteristic curve analysis was 25 kg/m2, and the proportion of patients with BMI ≥ 25 kg/m2 (89% vs. 31%, p < 0.001) was significantly higher in the HALS conversion versus pure LLR group. In the open conversion group, although there were no significant differences compared to the HALS group in clinicopathological factors except for sex, blood loss was greater (1425 vs. 367 mL; p < 0.001). CONCLUSION: Risk factors for considering HALS during LLR were patients with a history of upper abdominal surgery including repeat hepatectomy, BMI ≥ 25 kg/m2, S7 or S8 tumor location, DS ≥ 7, and prolonged surgical time. Furthermore, uncontrollable intraoperative bleeding was an indication for open conversion.

Hand-Assisted Laparoscopic Subtotal Colectomy for Ogilvie Syndrome Associated With Idiopathic Fibrosis of Colon After Simultaneous Pancreas Kidney Transplant.

Ogilvie syndrome (acute colonic pseudo-obstruction) is a rare, acquired, life-threatening disorder for which treatment plans vary from simple observation to surgical intervention. Ogilvie syndrome has been reported in patients after renal or liver transplant, but its occurrence after simultaneous pancreas-kidney transplant is rare. Herein, we present the case of a 45-year-old female recipient of a deceased donor simultaneous pancreas-kidney transplant who developed Ogilvie syndrome 10 days after a previous fecal ileus that had resolved at posttransplant week 3. She demonstrated Ogilvie syndrome with obstructive colitis features (severe abdominal pain and high-grade fever), which we immediately treated with colonic decompensation by placement of a transanal ileus tube. After several screening examinations and discontinuation of unnecessary medicines, we were not able to confirm the cause of Ogilvie syndrome in our patient. After 2 weeks, the patient remained unresponsive to the conservative treatment, and so hand-assisted laparoscopic subtotal colectomy was performed to remove the dilated colon. Her symptoms gradually resolved after surgery. Histologically, we confirmed submucosal fibrotic changes, especially at the distal end of the resected colon, without evidence of amyloidosis, and the number of Auerbach plexus ganglia had decreased. Nevertheless, we observed no degenerated appearance of ganglion cells in the Auerbach plexus or the Meissner plexus. After exclusion of several collagen diseases, including systemic sclerosis, we determined that idiopathic colonic fibrosis was the likely cause of Ogilvie syndrome in our patient. When surgery is indicated in transplant patients with Ogilvie syndrome with obstructive colitis features, colectomy should be considered.

Incidence of incisional hernia after laparoscopic liver resection.

BACKGROUND: Minimally invasive techniques have been broadly introduced to liver surgery during the last couple of years. In this study, we aimed to report the incidence and potential risk factors for incisional hernia (IH) as well as health-related quality of life (HRQoL) after laparoscopic liver resections (LLR). METHODS: All patients undergoing LLR between January 2014 and June 2017 were contacted for an outpatient hernia examination. In all eligible patients, photo documentation of the scar was performed and IH was evaluated by clinical examination and by ultrasound. Patients also completed a questionnaire to evaluate IH-specific symptoms and HRQoL. Obtained results were retrospectively analyzed with regard to patients' characteristics, perioperative outcomes and applied minimally invasive techniques, such as multi-incision laparoscopic liver surgery or hand-assisted/single-incision laparoscopic surgery (HALS/SILS). RESULTS: Of 184 patients undergoing surgery, 161 (87.5%) met the inclusion criteria and 49 patients (26.6%) participated in this study. After a median time of 26 months (range 19-50 months) after surgery, we observed an overall incidence of IH of 12%. Five of 6 patients were overweight or obese (BMI ≥ 25) and 5 of 6 hernias were located at the umbilical site. Univariate analysis suggested the performance status at time of operation (ASA score ≥ 3; HR 5.616, 95% CI 1.012-31.157, p = 0.048) and the approach (HALS/SILS, HR 6.571, 95% CI 1.097-39.379, p = 0.039) as potential risk factors for IH. A higher frequency of hernia-related physical restrictions (HRR; p = 0.058) and a decreased physical functioning (p = 0.17) were noted in patients with IH; however, both being short of statistical significance. CONCLUSION: Advantages of laparoscopic surgery with regard to low rates of IH can be translated to minimally invasive liver surgery. Even though there are low rates of IH, patients with poor performance status at the time of operation should be monitored closely. While patients' characteristics are hard to influence, it might be worth focusing on surgical factors such as the approach and the closure of the umbilical site to further minimize the rate of IH.

A propensity-matched study of full laparoscopic versus hand-assisted minimal-invasive liver surgery.

BACKGROUND AND AIM: The implications of multi-incision (MILS) and hand-assisted (HALS) laparoscopic techniques for minimally invasive liver surgery with regard to perioperative outcomes are not well defined. The purpose of this study was to compare MILS and HALS using propensity score matching. METHODS: 309 patients underwent laparoscopic liver resections (LLR) between January 2013 and June 2018. Perioperative outcomes were analyzed after a 1:1 propensity score match. Subgroup analyses of matched groups, i.e., radical lymphadenectomy (LAD) as well as resections of posterosuperior segments (VII and/or VIII), were performed. RESULTS: MILS was used in 187 (65.2%) and HALS in 100 (34.8%) cases, with a significant decrease of HALS resections over time (p = 0.001). There were no significant differences with regard to age, sex, body mass index (BMI), American Society of Anesthesiologists (ASA) Score, previous abdominal surgery and cirrhosis between both groups. Patients scheduled for HALS were characterized by a significantly higher rate of malignant tumors (p < 0.001) and major resections (p < 0.001). After propensity score matching (PMS), 70 cases remained in each group and all preoperative variables as well as resection extend were well balanced. A significantly higher rate of radical LAD (p = 0.039) and posterosuperior resections was found in the HALS group (p = 0.021). No significant differences between the matched groups were observed regarding operation time, conversion rate, frequency of major complications, length of intensive care unit (ICU) stay, overall hospital stay and R1 rate. CONCLUSION: Our analysis suggests MILS and HALS to be equivalent regarding postoperative outcomes. HALS might be particularly helpful to accomplish complex surgical procedures during earlier stages of the learning curve.

Verification of oncological local control for hand-assisted laparoscopic abdominal lymph node dissection in esophageal cancer surgery: a propensity score-matched analysis.

BACKGROUND: In esophageal cancer, long-term outcomes of minimally invasive surgery using endoscopic surgery are currently being verified. However, most trials have compared thoracic procedures; few studies have focused on the abdominal procedures, which are important for lymph node dissection in radical esophageal cancer surgery. Hand-assisted laparoscopic surgery (HALS) is a simple and minimally invasive procedure. Although HALS superiority in short-term outcomes has been reported, its oncological safety in esophageal cancer remains unclear. Therefore, we retrospectively evaluated oncological safety of HALS compared with that of conventional open laparotomy (OL) in radical surgery for thoracic and abdominal esophageal cancer. METHODS: We retrospectively analyzed the postoperative survival in 142 patients who underwent radical esophageal cancer surgery at our hospital between May 2012 and May 2017, with and without propensity score matching (PSM) between groups. RESULTS: Before PSM, OL (n = 65) and HALS (n = 77) groups differed significantly in overall survival (OS) (3-year OS rate: 74.2% and 87.3%, respectively; log-rank p = 0.040). Additionally, clinical abdominal lymph node metastasis (cALNM) independently predicted OS (p = 0.031). After PSM, the OL and HALS groups did not differ significantly in OS (3-year OS rate: 80.5% and 89.8%, respectively; log-rank p = 0.716). There was no statistically significant difference in abdominal-specific recurrence-free survival between the OL and HALS group before and after PSM. CONCLUSION: HALS may be a well-accepted procedure for radical esophagectomy in esophageal cancer, with oncological safety, including local control specific to the abdomen, comparable to that of the conventional OL.

Outcomes and surgical complications following living-donor renal transplantation using kidneys retrieved with trans-peritoneal or retro-peritoneal hand-assisted laparoscopic nephrectomy.

The best minimally invasive procedure for living-donor kidney retrieval remains debated. Our objective was to assess trans-peritoneal (TP) and retro-peritoneal (RP) hand-assisted laparoscopic donor nephrectomy (HALDN). In this single-center retrospective study, we analyzed results from 317 living-donor renal transplants (RT) performed between 2008 and 2016. Donor and recipient outcomes were compared between TP-HALDN (n = 235) and RP-HALDN (n = 82). Conversion to open nephrectomy (0.4% vs 0%; P = 1.000), intra-operative complications (1.7% vs 1.2%; P = 1.000), and 1-year overall post-operative complications (11.9% vs 17.1%; P = .258) rates were similar in TP-HALDN and RP-HALDN. Overall surgical site infections were higher in RP-HALDN (6.1% vs 1.7%; P = .053), whereas incisional hernias were only recorded following TP-HALDN (3.4% vs 0%; P = .118). The duration of the procedure was 11-minute shorter for TP-HALDN than RP-HALDN (P < .001) but extraction time was equivalent (2, IQR 1.5-2.5 minutes; P = 1.000). RT following TP-HALDN and RP-HALDN showed comparable one-year death-censored allograft survival (97% vs 98.8%; P = .685), primary non-function (0.4% vs 0%; P = .290), delayed graft function (1.3% vs 4.9%; P = .077), and urological complications (2.6% vs 4.9%; P = .290) rates. In our series, donor and recipient outcomes were not substantially affected by the approach used for donor nephrectomy. TP-HALDN and RP-HALDN were both safe and effective.

Simultaneous Hand-assisted Laparoscopic Bilateral Native Nephrectomy and Kidney Transplantation for Patients With Large Polycystic Kidneys.

OBJECTIVE: To describe our technique of simultaneous hand-assisted laparoscopic bilateral native nephrectomy (BNN) and kidney transplantation (KT) in patients with autosomal dominant polycystic kidney disease and present our experience. MATERIALS AND METHODS: We retrospectively reviewed a cohort of adult ESRD patients with symptomatic autosomal dominant polycystic kidney disease who underwent a hand-assisted laparoscopic BNN at the time of KT. We reviewed patients' and donor characteristics, and perioperative and postoperative outcomes. RESULTS: A total of 52 patients underwent hand-assisted laparoscopic BNN at the time of KT from January 2014 to October 2019. The median age of the recipients was 53.4 years, 57.7% were males, and the median body mass index was 29.0 kg/m2. All but one received a kidney from a living donor and the majority (86.5%) were pre-emptive. One patient required a small bowel resection due to an intraoperative small bowel injury. There was no solid organ injury during the procedure. All patients showed immediate allograft function and a steady decline in serum creatinine. The median decline in the creatinine and hemoglobin on day 1 was 1.2 mg/dL (inter quartile range 0.6-2.3) and 2.2 g/dL (inter quartile range 1.4-3.0), respectively. CONCLUSION: Simultaneous hand-assisted laparoscopic bilateral nephrectomy with KT through a modified Gibson incision is feasible and safe in the hands of an experienced laparoscopic surgeon without compromising allograft function.

Changes in Muscle Quality and Body Composition 1 Year After Hand-Assisted Laparoscopic Donor Nephrectomy in Living Kidney Donors.

OBJECTIVES: Our aim was to investigate effects of surgery on living donors' body composition and clarify factors related to it. MATERIALS AND METHODS: We evaluated preoperative computed tomography images of 335 living kidney donors (127 men, 209 women) to calculate 3 body composition parameters and changes with aging by sex: (1) skeletal muscle mass, quantified by skeletal muscle index; (2) fat distribution, calculated by visceral adipose tissue/subcutaneous adipose tissue ratio; and (3) muscle quality, quantified by intramuscular adipose tissue content. Thereafter, with pre- and postoperative computed tomography images from 75 living kidney donors (25 men, 50 women) after hand-assisted laparoscopic donor nephrectomy, we compared pre- and postoperative body composition changes. RESULTS: Annual change in intramuscular adipose tissue content with age was 0.0049 in men and 0.0091 in women. Of 75 patients, 49 had lower quality of muscle, intramuscular adipose tissue content was significantly higher after nephrectomy (P < .001), and median change in intramuscular adipose tissue content was 0.061 (range, 0.018-0.11) in men and 0.052 (range, 0.017-0.18) in women. Univariate analysis revealed that skeletal mass index and visceral adipose tissue/subcutaneous adipose tissue ratio changes were significantly different between the intramuscular adipose tissue content improvement and deterioration groups. Multivariate analysis revealed skeletal mass index change was an independent factor for intramuscular adipose tissue content change (P = .0019). Intramuscular adipose tissue content change was negatively correlated with skeletal mass index change (r = -0.40). CONCLUSIONS: Although muscle quality deteriorates after nephrectomy, maintaining muscle mass is important to retaining muscle quality.

A meta-analysis comparing hand-assisted laparoscopic right hemicolectomy and open right hemicolectomy for right-sided colon cancer.

BACKGROUND: Mini-invasive colorectal cancer surgery was adopted widely in recent years. This meta-analysis aimed to compare hand-assisted laparoscopic surgery (HALS) with open right hemicolectomy (OS) for malignant disease. METHODS: PRISMA guidelines with random effects model were adopted using Review Manager Version 5.3 for pooled estimates. RESULTS: Seven studies that involved 506 patients were included. Compared to OS, HALS improved results in terms of blood loss (MD = 53.67, 95% CI 10.67 to 96.67, p = 0.01), time to first flatus (MD = 21.11, 95% CI 14.99 to 27.23, p < 0.00001), postoperative pain score, and overall hospital stay (MD = 3.47, 95% CI 2.12 to 4.82, p < 0.00001). There was no difference as concerns post-operative mortality, morbidity (OR = 1.55, 95% CI 0.89 to 2.7, p = 0.12), wound infection (OR = 1.69, 95% CI 0.60 to 4.76, p = 0.32), operative time (MD = - 16.10, 95% CI [- 36.57 to 4.36], p = 0.12), harvested lymph nodes (MD = 0.59, 95% CI - 0.18 to 1.36, p = 0.13), and recurrence (OR = 0.97, 95% CI 0.30 to 3.15, p = 0.96). CONCLUSIONS: HALS is an efficient alternative to OS in right colectomy which combines the advantages of OS with the mini-invasive surgery.

Preoperative assessment system for hand-assisted laparoscopic donor nephrectomy by discriminant analysis.

We developed a preoperative assessment system to predict surgical workload in hand-assisted laparoscopic donor nephrectomy (HALDNx) using the normal-based linear discriminant rule (NLDR). A total of 128 cases of left HALDNx performed by a single operator were used as training data. Surgical workload was measured by operative time. The optimized model had 9 explanatory variables: age, total protein, total cholesterol, number of renal arteries (numberRA), 4 variables of perinephric fat (PNF), and thickness of subcutaneous fat. This model was validated using cross-validation and the .632 estimator to estimate discrimination rates with future test data. PNF and numberRA were the predominant factors affecting workload followed by the computed tomography value of PNF, body weight, and male sex. The estimated accuracy of the prediction system was 94.6%. The complication rate was 9.38% and did not correlate with surgical workload. We also made our program available online for constructing assessment functions from other cohort data. In conclusion, the surgical workload of HALDNx could be predicted with PNF and numberRA as the dominant risk factors.

Hand-assisted Laparoscopic Nephrectomy: Evaluation of the Learning Curve.

BACKGROUND: Hand-assisted laparoscopic donor nephrectomy (HALDN) has rapidly become the best alternative to open nephrectomy for living kidney donation. As more centers continue to adopt the laparoscopic technique, the safety of the initial transplants must be ensured while ascending the learning curve (LC). This study looks to determine the safety of HALDN and to describe the results of the LC in our center. METHODS: We conducted a retrospective review of 500 HALDNs performed in our center from July 2003 to July 2017. We analyzed demographic and perioperative characteristics and complications during the first postoperative month. We divided HALDNs into 2 groups: before and after completing the LC (50 nephrectomies). For each group, we assessed operating room time, estimated blood loss, length of stay, and complication and conversion rates. RESULTS: A total of 500 HALDNs were performed in the study period. Of those, 454 were analyzed in the 2 groups. The median operating room time was 2 hours, length of stay was 2 days, and blood loss was 50 cc. The overall rate of complication was 6.8%. There were significant differences between the 2 groups in operating time, blood loss, and length of stay (P < .05). No differences were found in terms of complication (P = .42) and conversion (P = .28) rates. CONCLUSION: There was a significant decrease in operating time, blood loss, and length of stay in patients who underwent laparoscopic donor nephrectomy by an experienced laparoscopist. However, no differences were found in complication and conversion rates, which suggests that improvement in surgical training can be accomplished without altering the donor safety.

Morbidity Following Hand-Assisted Laparoscopic Donor Nephrectomy.

Background: The incidence of morbidity and readmission rate after hand-assisted laparoscopic donor nephrectomy (HALDN) is not clear. Aims: Our study aims to review our experience with HALDN, mainly the reasons for patient readmissions. Methods: Prospectively collected data on all patients undergoing HALDNs between August 2007 and June 2015 were retrieved. The primary outcome was 30-day readmission rate. Secondary outcomes were complications and readmission etiology. Results: There were 161 nephrectomies with a median age of 51 years, 72 (44.7%) men, and 114 (70.8%) left-sided operations. Twenty-one (13%) individuals were readmitted within 30 days. There were total 25 (15.5%) readmissions during the study period. The characteristics of patients readmitted and patients not readmitted were broadly similar. Nine of 21 (43%) individuals readmitted had nonspecific findings (nonspecific findings on imaging, negative blood cultures, and raised inflammatory markers). The reasons for readmission were unrelated to nephrectomy in 24% and 19% required surgery for complications unrelated to nephrectomy. Conclusion: We observed a high readmission rate after HALDN. A significant proportion of readmissions were due to nonspecific abdominal pain associated with raised inflammatory markers and no obvious source of sepsis. Living donors should be fully informed about the risks including the possibility of complications unrelated to HALDN.

It Is Not Just Cosmesis: Straight Laparoscopy with Stoma Site Extraction Improves Outcomes in Ulcerative Colitis Patients Undergoing Total Colectomy.

Minimally invasive approaches to total abdominal colectomy (TAC) in ulcerative colitis (UC) patients include straight laparoscopy (SL), hand-assisted laparoscopic surgery (HALS), and robotics. In this study, short-term outcomes of patients undergoing SL and HALS TAC were compared. Prospectively collected data on UC patients undergoing TAC were tabulated. The study cohort included 36 (27%) patients in the SL group and 95 (73%) patients in the HALS group. The groups were comparable in terms of preoperative characteristics and demographics. The mean operative time was 151 (range, 73-225) minutes in the SL group versus 164 (range, 103-295) minutes in the HALS group (P = 0.09). Total 48-hour IV morphine use was 30 (range, 0-186) mg in the SL group compared with 56 (0-275) mg in the HALS group (P < 0.01). Although overall morbidity was comparable between the groups, Clavien-Dindo Class III complications did not occur in any of the SL group patients versus 11 (11%) of the HALS group patients (P = 0.03). The postoperative length of stay was 3 (3-21) days in the SL group versus 5 (3-15) days in the HALS group (P < 0.01). Compared with HALS, SL is associated with lower postoperative narcotic use and hospital length of stay in UC patients undergoing TAC.

Propensity Score-Matched Analysis of Pure Laparoscopic Versus Hand-Assisted/Hybrid Major Hepatectomy at Two Western Centers.

BACKGROUND: Laparoscopic major hepatectomy is expanding, but little data exist comparing surgical approaches. The aim of this study was to test the hypothesis that pure laparoscopic liver resection (PLAP) has advantages over hand-assisted (HALS) or hybrid (HYB) resection for major hemi-hepatectomy at two western centers. METHODS: Using propensity score matching, 65 cases of HALS + HYB (18 hand-assisted and 47 hybrid) were matched to 65 cases of PLAP. Baseline characteristics were well matched for gender, age, ASA score, Childs A cirrhosis, right/left hepatectomy, malignancy, tumor size, and type between the groups. RESULTS: The HALS + HYB group had 27 right and 38 left major hepatectomies (n = 65) versus 29 right and 36 left (n = 65) in the PLAP group (p = NS). The median number of lesions resected was 1 in each group, with median size 5.6 cm (HALS + HYB) versus 6.0 cm (PLAP), (p = NS). The HALS + HYB group had shorter OR time (240 versus 330 min, p < 0.01), and less blood loss (EBL 150 ml vs. 300 ml, p < 0.01) versus the PLAP group, respectively. Median length of stay (LOS) was 4 days with HALS + HYB versus 5 days in the PLAP group (p = 0.02). There were no significant differences in use of the Pringle maneuver, transfusion rate, ICU stay, post-op morbidity, liver-specific complications, or R0 resection. Pain regimen/usage in each group is provided. There were no 30/90-day deaths in either group. CONCLUSION: This is the first reported series of propensity score matching of HALS + HYB versus PLAP for major hepatectomy. The HALS + HYB group had non-inferior OR time, blood loss, and LOS versus the PLAP group, while the other perioperative parameters were comparable. We conclude that minimally invasive liver resection with either PLAP or HALS + HYB technique yields excellent results.

Hand-assisted laparoscopic surgery versus endovascular repair in abdominal aortic aneurysm treatment.

OBJECTIVE: Hand-assisted laparoscopic surgery (HALS) for the treatment of abdominal aortic aneurysm (AAA) has shown promising initial results compared with traditional surgery, but its efficacy remains highly debated. The aim of this monocentric, retrospective study was to investigate differences in morbidity, mortality, and reintervention rates between endovascular aneurysm repair (EVAR) and HALS, in the medium- and long-term follow-up in a highly selected population. METHODS: We treated 977 patients consecutively for nonurgent AAA from January 2006 to December 2013; among them, 615 (62.9%) underwent open surgery, 173 (17.7%) HALS, and 189 (19.3%) EVAR. For this study, only patients treated with HALS or EVAR were considered. A subsequent selection process was carried out to identify the patients with clinical characteristics and aneurysm morphology amenable to either of these treatments. The final study cohort included 229 patients; 92 (40.2%) underwent HALS and 137 (69.8%) received EVAR. The two populations were homogeneous for clinical and demographic characteristics. RESULTS: The mean duration of follow-up was 57 ± 28 months (50 ± 24 months in the EVAR group and 67 ± 29 months in the HALS group; range, 2-110 months). No deaths and no statistically significant differences in severe complications or reinterventions were observed over the perioperative period (30 days). Length of stay was significantly shorter after EVAR, because the need for and length of stay in the intensive care unit were decreased. Three postoperative deaths (in-hospital mortality >30 days: HALS, 2.2%; EVAR, 0.7%; P = .7268) occurred owing to respiratory failure (two patients, one in each group) and multiorgan failure secondary to a bowel ischemia (one patient in the HALS group). Other deaths in the study population were not related to the procedure. In both groups, the major causes of death were cancer (24 cases [36.9%]), cardiovascular causes unrelated to AAA (16 [24.6%]), and chronic obstructive lung disease (10 [15.4%]). In the long-term follow-up period, there was a difference in the overall survival in favor of HALS when compared with EVAR (P = .011). CONCLUSIONS: This retrospective, single-center study shows that, within a population of similar clinical and anatomic characteristics, treatment of AAA with EVAR or HALS does not result in significant differences in early morbidity and mortality. EVAR presents significantly shorter hospital and intensive care unit length of stay, whereas HALS presents a lower aneurysm-related reintervention rate and lower perioperative cost. The strict patient selection in this trial, as is generally the case with AAA treatment, is likely the key to success for both of these techniques.
