A modified open primary laparoscopic surgery port placement through umbilical tube

Background:A safe, reliable technique for primary trocar introduction is important for laparoscopic surgery. In resource-constrained settings where there is paucity of needed equipment and cost is prohibitive, a method utilizing fewer instruments will be useful.Aim:This study aims to describe a method of primary trocar introduction that utilizes any available port.Methods:A supra- or infra-umbilical incision is made into an everted tubular umbilicus. The linear alba is incised and the resultant opening bluntly developed, after which any available port is inserted using the trocar as a guide. The trocar is withdrawn while the sleeve is pushed in.Results:One hundred and three successful insertions were affected in 107 patients with age range of 1­75 years, with no significant gas leaks.Conclusion:This modified open approach is a simple and reliable way of primary port insertion. Access is gained easily in different age groups and umbilicus types

Laparoscopic nephrectomy outside gerota fascia and en bloc ligation of the renal hilum for management of inflammatory renal diseases

ABSTRACT Objectives This study aims to improve laparoscopic nephrectomy techniques for inflammatory renal diseases (IRD) and to reduce complications. Materials and Methods Thirty-three patients underwent laparoscopic nephrectomy for IRD, with a method of outside Gerota fascia dissection and en-bloc ligation and division of the renal pedicle. Operative time, blood loss, complications, analgesia requirement, post-operative recovery of intestinal function and hospital stay were recorded. The degrees of perinephric adhesion were classified based on the observation during operation and post-operative dissection of the specimen, and the association of different types of adhesion with the difficulty of the procedures was examined. Results Among 33 cases, three were converted to hand-assisted laparoscopy, and one was converted to open surgery. Mean operative time was 99.6±29.2min, and blood loss was 75.2±83.5 mL. Postoperative recovery time of intestinal function was 1.6±0.7 days and average hospital stay was 4.8±1.4 days. By classification and comparison of the perinephric adhesions, whether inflammation extending beyond Gerota fascia or involving renal hilum was found to be not only an important factor influencing the operative time and blood loss, but also the main reason for conversion to hand-assisted laparoscopy or open surgery. Conclusions In laparoscopic nephrectomy, outside Gerota fascia dissection of the kidney and en-bloc ligation of the renal pedicle using EndoGIA could reduce the difficulty of procedure and operative time, with satisfactory safety and reliability. Inflammation and adhesion extending beyond Gerota fascia or involving renal hilum is an important predictor of the difficulty related to laparoscopic nephrectomy for IRD.

Does a wrist tourniquet improve the quality of Biers block for surgeries in the hand?

This study aims to determine the effect of a wrist tourniquet on Biers Block quality for short hand procedures. 40 patients were randomized into 2 groups. One had the intravenous lignocaine injected with a wrist rubber tourniquet in situ, While the control group had none during injection. The onset of block, sensation, motor activity, need for additional analgesia and duration of surgeries were recorded for each group and analysed statistically. 27 males and 13 females were recruited. Mean onset for the tourniquet group was 4.3minutes and 9.0 minutes for the control (p< ˂0.0000005), Visual analog Pain Scores were 0.2 for Tourniquet and 1.8 for control (p< 0.0003) at 15 minutes. Sensory and motor block scores were significantly higher at 15 minutes following anaesthetic agent administration in the tourniquet group compared to the control(p<0.05). At 30 minutes there was no statistically significant difference in the scores. There was also no difference in the need for additional analgesia in either group. It appears that the use of a wrist tourniquet shortens the onset of Biers block for hand surgeries. However, it does not improve overall block quality after 30 minutes of administration but allowed a smaller dosage to be used with fewer side effects

Safety and efficacy of hand-assisted laparoscopic versus open distal gastrectomy for gastric cancer: A systematic review and meta-analysis / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To systematically assess the safety and efficacy of hand-assisted laparoscopic distal gastrectomy (HALG) versus open distal gastrectomy (ODG) for gastric cancer.</p><p><b>METHODS</b>Chinese or English literature regarding comparison of HALG and ODG were collected by searching in databases (such as PubMed, Cochrane Library, CNKI, Wanfang database) between January 1996 and September 2016. The data of operative time, incision length, blood loss, number of harvested lymph nodes, time to flatus, hospital stay, postoperative complication morbidity and long-term outcomes were compared between the two procedures. Then funnel plot was used to evaluate publication bias and sensitivity analysis was used to evaluate the stability of the results. All these data analyses were performed using the Meta for or Meta package of R version 3.3.1.</p><p><b>RESULTS</b>A total of 7 studies with 835 patients (323 cases in HALG group and 512 cases in ODG group) were included. Compared with ODG, HALG had a longer operative time (WMD=28.93 minutes, 95%CI=9.59 to 48.28, Z=2.93, P=0.000), a shorter incision length (WMD=-10.31 cm, 95%CI=-14.01 to -6.62, Z=-5.47, P=0.000), less blood loss (WMD=-140.08 ml, 95%CI=-215.07 to -65.09, Z=-3.66, P=0.000), faster gastrointestinal recovery (WMD=-1.23 days, 95%CI=-1.89 to -0.56, Z=-3.62, P=0.000), shorter postoperative hospital stay (WMD=-3.24 days, 95%CI=-5.47 to -1.02, Z=-2.85, P=0.000). In subgroup analysis, 3 studies published before 2013 vs. 4 studies published afterwards, the number of harvested lymph nodes (WMD=-0.78, 95%CI=-2.05 to 0.50, Z=-1.19, P=0.235) and postoperative complication morbidity (RR=1.02, 95%CI=0.43 to 2.44, Z=0.05, P=0.961) did not differ significantly between two groups. Compared with ODG, the RR(95%CI) of ileus of HALG was 0.43 (0.07 to 2.82), but the difference was not statistically significant (P=0.383). One study reported the 5-year overall survival rates of HALG and ODG were 81.0% vs 67.5%, and the tumor recurrence rates were 7.1% vs 22%, respectively, but the differences were not statistically significant(all P>0.05). Sensitivity analysis showed that the above results were stable. The funnel plots of the lymph nodes and postoperative complication morbidity did not present significant publication bias.</p><p><b>CONCLUSIONS</b>HALG has the advantages of minimal invasiveness such as shorter incision length and quicker recovery. Furthermore, the short-term efficacy of HALG is similar to conventional open surgery. However, the long-term efficacy is lack of support from multicenter long-term follow-up results.</p>

Choice of the mode of laparoscopic right hemicolectomy / 中华胃肠外科杂志

Laparoscopy has become the standard surgery mode of right hemicolectomy, including conventional laparoscopy, hand-assisted laparoscopic surgery (HALS), single-port laparoscopic surgery (SPLS), natural orifices translumenal endoscopic surgery (NOTES) and robotic laparoscopy. How to select reasonable laparoscopic mode could be confusing sometimes. For patients, safety, cost-effectiveness and radical cure of the surgery are very important. For doctors, advance and convenience of the surgery must be considered as well. How do we choose a win-win operation method Conventional laparoscopic surgery is the basis of all the minimally invasive surgeries, and total mesocolon resection with D3 lymphadenectomy is an important technical foundation of right hemicolectomy. HALS has some advantages in patients with obesity, abdominal surgery history, intestinal adhesion or intestinal obstruction. SPLS and NOTES have minimized abdominal trauma leading to faster recovery, but have certain technical difficulties, especially NOTES. Although robotic laparoscopic surgery is advanced, but its high cost limits its popularization. Surgeons should integrate their technical levels, hospital equipment, and conditions of patients, then choose reasonable operation mode of right hemicolectomy.

Outcomes of Hand-Assisted Laparoscopic Surgery for Colorectal Disease in an Emergency Setting

PURPOSE: Laparoscopic surgery is accepted as a standard alternative to open procedures in the management of both benign and malignant colorectal disease. However, the safety and efficacy of the laparoscopic approach for emergency colorectal surgery has not been established. Hand-assisted laparoscopic (HAL) surgery might be a suitable option for colectomy in an emergency setting. The aim of this study was to report our experience of emergency HAL colectomy. METHODS: This was a retrospective review of consecutive colorectal emergency cases that were treated using HAL colectomy. Patient demographics, indications for surgery, operative details, and postoperative complications were examined. RESULTS: From March 2015 to April 2016, 18 patients underwent emergency HAL colectomy for complicated colorectal disease. Eight patients (44%) had an obstruction that required intraoperative decompression procedure. Sixteen patients (89%) had a perforation (five of which were sealed perforations involving large abscesses and inflammatory changes). Eight patients underwent sigmoidectomy, four underwent anterior resection, one underwent low anterior resection, two underwent left hemicolectomy, and three underwent Hartmann's procedure. There were two instances of open conversion (11%). The median duration of surgery was 178 minutes. The median time to bowel function recovery and median postoperative stay were 3 days and 10 days, respectively. The postoperative complication rate associated with the operation was 33% (6/18). There was one postoperative mortality. CONCLUSION: For the experienced surgeon, HAL can be a reasonable option for emergency colorectal surgery.

Hand-Assisted Laparoscopic Nephrectomy and Auto-Transplantation for a Hilar Renal Artery Aneurysm: A Case Report

A 52-year-old man was admitted with an incidentally detected right renal artery aneurysm (RAA). Computed tomographic angiography with three-dimensional reconstruction revealed that the aneurysm was 2.2 cm in diameter and located at the renal hilum. We performed hand-assisted laparoscopic nephrectomy with ex vivo repair of the RAA and auto-transplantation with minimal elongation of Gibson incision. The operation and postoperative course were uneventful. At last follow-up, the patient was alive with a well-functioning auto-transplant. Hand-assisted laparoscopic nephrectomy and auto-transplantation is a useful treatment option for hilar RAA.

Hand-Assisted Laparoscopic Surgery: A Versatile Tool for Colorectal Surgeons

PURPOSE: Hand-assisted laparoscopic surgery (HALS) is a minimally invasive surgical technique with the combined benefits of laparoscopic surgery while allowing the use of the surgeon's hand for better tactile control. Obesity has been associated with higher conversion rates with multiport laparoscopic surgery, but not with HALS. This study aimed to examine the versatility of HALS in various clinical contexts. METHODS: All HALSs performed at 2 major tertiary centers in Sydney were prospectively collected for retrospective analysis. Variables including age, sex, body mass index (BMI), previous surgeries, pathologies including size and T-stage, and the number of conversions to a midline laparotomy were examined. RESULTS: A total of 121 HALS colorectal resections were analyzed. The median age of the patients was 62 years, with 63.6% being women. Seven patients required conversion to a midline laparotomy. Of the 121 patients, 50.2% were overweight or obese, and 52.9% had undergone previous abdominal/pelvic operations. However, neither obesity nor abdominal adhesions from previous operations were an indication for conversion to an open laparotomy in any of the 7 converted patients. The presence of intra-abdominal adhesions did not impact the operative time. HALS allowed access to the entire colon and rectum and allowed resection of the bladder, uterus, and ureter, when these organs were involved. CONCLUSION: HALS is a versatile, minimally invasive technique, which is independent of the patient's BMI, for performing a colorectal resection.

Complete mesocolic excision in right hemicolectomy: comparison between hand-assisted laparoscopic and open approaches

PURPOSE: To demonstrate the feasibility, safety, and technical strategies of hand-assisted laparoscopic complete mesocolic excision (HAL-CME) and to compare oncological outcomes between HAL-CME and the open approach (O-CME) for right colon cancers. METHODS: Patients who were scheduled to undergo a right hemicolectomy were divided into HAL-CME and O-CME groups. Measured outcomes included demographic variables, perioperative parameters, and follow-up data. Demographic variables included age, sex distribution, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, previous abdominal surgery, tumor localization, and potential comorbidities. Perioperative parameters included incision length, operative time, blood loss, conversion rate, postoperative pain score, postoperative first passage of flatus, duration of hospital stay, total cost, number of lymph nodes retrieved, TNM classification, and postoperative complications. Follow-up data included follow-up time, use of chemotherapy, local recurrence rate, distant metastasis rate, and short-term survival rate. RESULTS: In total, 150 patients (HAL-CME, 78; O-CME, 72) were included. The groups were similar in age, sex distribution, BMI, ASA classification, history of previous abdominal surgeries, tumor localization, and potential comorbidities. Patients in the HAL-CME group had shorter incision lengths, longer operative times, less operative blood loss, lower pain scores, earlier first passage of flatus, shorter hospital stay, higher total costs, similar numbers of lymph nodes retrieved, similar TNM classifications, and a comparable incidence of postoperative complications. The 2 groups were also similar in local recurrence rate, distant metastasis rate, and short-term survival rate. CONCLUSION: The results demonstrate that the HAL-CME procedure is a safe, valid, and feasible surgical method for right hemicolon cancers.

Hand-assisted Laparoscopic Donor Surgery for Living Donor Pancreas and Kidney Transplantation: A Single Center Experience / 대한이식학회지

BACKGROUND: In this era of donor shortage, use of organs from living donors has increased significantly. Nonetheless, less than 1% of pancreas transplantations involve living donors, despite the immunological benefits, reduced cold ischemic time, and decreased waiting time. One reason for the paucity of donors is the high morbidity after open surgery. Using hand-assisted laparoscopic donor surgery (HALDS) can be a favorable technique for living donors. METHODS: Using HALDS, we performed three Simultaneous pancreas-kidney transplantations (SPKs) involving living donors. Two donors were women; one was a man. RESULTS: Their mean age was 34.3±4.7 years, and their body mass index was 23.2±2.36 kg/m². The mean operation time was 241±19.0 minutes and the mean cold-ischemic time of the kidney was 42.7±9.8 minutes, while that of the pancreas was 64.3±5.2 minutes. One donor developed a pancreatic fistula, which was controlled using conservative management. The donors' pancreatic and renal functions were well preserved postoperatively. CONCLUSIONS: HALDS for SPKs can be performed without significant complications if the surgeon has sufficient skill.

Laparoscopic surgery for left-sided colon cancer: Clinical and long-term oncologic outcomes

PURPOSE: Laparoscopic surgery for left-sided colon cancer is one of the most frequent procedures performed in laparoscopic colorectal surgery. In this study, we analyzed clinical and long-term oncological outcomes of left-sided colon cancer patients who underwent conventional laparoscopic surgery (CLS) and hand-assisted laparoscopic surgery (HALS).METHODS: A total of 172 CLS patients and 72 HALS patients for left-sided colon cancer from July 2001 to December 2011 were included in this study. The collected data included the clinical and oncological outcomes. We analyzed overall survival and disease-free survival by tumor, node, metastasis (TNM) stage.RESULTS: The mean age of the patients was 64 years, and male patients were predominant. The mean follow-up period was 58.1 months. The number of patients that belong in each TNM stage 0, I, II, III, and IV was as follows: 17 (7%), 47 (19.2%), 70 (28.7%), 80 (32.8%), and 30 (12.3%), respectively. Overall 5-year survival rate for TNM stage I, II, III, and IV was 87.1%, 82.8%, 82%, and 12%, respectively. Overall 5-year survival rate for CLS group and HALS group was 90.2% and 66.7%, 86.5% and 77%, 88.7% and 67.4%, and 18.9% and 0%, respectively. Disease-free 5-year survival rate for TNM stage I, II, and III was 97.7%, 90.7%, and 72.8%, respectively. Disease-free 5-year survival rate for CLS group and HALS group was 97.3% and 100%, 100% and 78.8%, and 81% and 55.1%, respectively.CONCLUSION: These data show the feasibility and safety of laparoscopic surgery for left-sided colon cancer in terms of long-term oncological outcomes.

Surgical time and complications of total transvaginal (total-NOTES), single-port laparoscopic-assisted and conventional ovariohysterectomy in bitches / Tempo cirúrgico e das complicações entre as técnicas de ovário-histerectomia totalmente transvaginal (total-NOTES), videoassistida com único portal e convencional em cadelas

The recently developed minimally invasive techniques of ovariohysterectomy (OVH) have been studied in dogs in order to optimize their benefits and decrease risks to the patients. The purpose of this study was to compare surgical time, complications and technical difficulties of transvaginal total-NOTES, single-port laparoscopic-assisted and conventional OVH in bitches. Twelve bitches were submitted to total-NOTES (NOTES group), while 13 underwent single-port laparoscopic-assisted (SPLA group) and 15 were submitted to conventional OVH (OPEN group). Intra-operative period was divided into 7 stages: (1) access to abdominal cavity; (2) pneumoperitoneum; approach to the right (3) and left (4) ovarian pedicle and uterine body (5); (6) abdominal or vaginal synthesis, performed in 6 out of 12 patients of NOTES; (7) inoperative time. Overall and stages operative times, intra and postoperative complications and technical difficulties were compared among groups. Mean overall surgical time in NOTES (25.7±6.8 minutes) and SPLA (23.1±4.0 minutes) groups were shorter than in the OPEN group (34.0±6.4 minutes) (P<0.05). The intraoperative stage that required the longest time was the approach to the uterine body in the NOTES group and abdominal and cutaneous sutures in the OPEN group. There was no difference regarding the rates of complications. Major complications included postoperative bleeding requiring reoperation in a bitch in the OPEN group, while minor complications included mild vaginal discharge in four patients in the NOTES group and seroma in three bitches in the SPLA group. In conclusion, total-NOTES and SPLA OVH were less time-consuming then conventional OVH in bitches. All techniques presented complications, which were properly managed.

O emprego de novas técnicas minimamente invasivas de ovário-histerectomia (OHE) vem sendo estudado em cães com o intuito de otimizar seus benefícios e reduzir os riscos aos pacientes. O presente estudo objetivou comparar o tempo cirúrgico, as complicações e dificuldades técnicas entre as abordagens por total-NOTES transvaginal, videoassistida com único portal e por celiotomia para ovário-histerectomia (OVH) em cadelas. Foram operados 12 animais por total-NOTES (grupo NOTES), 13 pela técnica videoassistida (grupo SPLA) e 15 pela técnica convencional (grupo OPEN). O período intraoperatório foi dividido em sete etapas: (1) acesso à cavidade abdominal; (2) criação do pneumoperitônio; abordagem ao pedículo ovariano direito (3), esquerdo (4) e ao corpo uterino (5); (6) síntese abdominal ou vaginal, realizado em seis de 12 pacientes do grupo NOTES; (7) tempo inoperante. Os parâmetros avaliados foram o tempo cirúrgico total e de cada etapa intraoperatória, a frequência de complicações intra e pós-operatórias e dificuldades técnicas. O tempo cirúrgico total médio dos grupos NOTES (25,7±6,8 minutos) e SPVA (23,1±4,0 minutos) foram menores que o do grupo OPEN (34,0±6,4 minutos) (P<0.05). A etapa intraoperatória que demandou maior tempo de execução foi a abordagem ao corpo uterino para o grupo NOTES, e síntese abdominal e cutânea para o grupo OPEN. Uma cadela do grupo OPEN necessitou de reintervenção para controle de hemorragia como complicação maior, e três cadelas do grupo SPVA apresentaram seroma de ferida cirúrgica como complicações menores. Concluiu-se que as técnicas de total-NOTES e SPLA apresentaram menor tempo cirúrgico que a abordagem convencional de OVH em cadelas. Todas as técnicas apresentaram complicações que foram adequadamente manejadas.

Two-handed assisted laparoscopic surgery: Evaluation in an animal model

Purposes To evaluate in an animal model the feasibility of a novel concept of hand-assisted surgery consisting of inserting two hands into the abdomen instead of one. The chosen procedure was retroperitoneal lymph node dissection (L-RPLND) that was performed in five pigs. Surgical Technique A Pfannestiel and a transverse epigastric incisions were made through which both hands were introduced. The scope was inserted through the umbilicus. The colon was moved medially and the dissection was performed as in open surgery using short conventional surgical instruments. Comments The surgery was fulfilled easily and safely in quite a similar way as in open surgery. Two-handed laparoscopy may be indicated in cases that still today require an open approach as apparently makes the operation easier and significantly shortens the surgery time. However, new opinions and trials are required. .

Efficacy analysis of laparoscopic surgery for primary local gastric and intestinal gastrointestinal stromal tumors / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To investigate the feasibility and short-term efficacy of laparoscopic resection of primary local gastric and intestinal gastrointestinal stromal tumors(GIST).</p><p><b>METHODS</b>Clinicopathological data of 26 patients with GIST, 20 located at the stomach and 6 at the intestine, undergoing laparoscopic complete resection from October 2010 to April 2013 were retrospectively analyzed.</p><p><b>RESULTS</b>Hand-assisted laparoscopic surgery was performed in 3 patients with gastric GIST, while the other 23 underwent regular laparoscopic surgery. All the procedures were performed successfully without conversion to open operation. According to tumor location and growth types, gastric local resection was performed in 18 cases, distal gastrectomy in 2 cases and intestinal segmental resection in all 6 cases of intestinal GIST. The mean diameter of tumor was (4.5±1.6) cm. The mean operational time was(96.2±28.2) min, with a mean blood loss of (49.6±38.6) ml. Postoperative bowel function recovery time was (2.3±0.7) d and the length of postoperative hospital stay was (6.8±1.9) d. Bleeding from gastrointestinal tract developed in 1 patient after resection of intestinal GIST. Postoperative pathology indicated very low risk of GIST in 1(3.8%), low risk in 13(50.0%), intermediate in 9(34.6%) and high risk in 3(11.5%) patients, respectively. After a follow-up ranging form 3 to 32 months, no recurrence or death was found.</p><p><b>CONCLUSION</b>Laparoscopic surgery of primary local GISTs from stomach or intestine is safe and feasible in selected patients, with less invasiveness, rapid recovery, and favorable short-term outcomes.</p>
