Overview of single-port laparoscopic surgery for colorectal cancers: Past, present, and the future

Single-port laparoscopic surgery(SPLS)is implemented through a tailored minimal single incision through which a number of laparoscopic instruments access.Introduction of operation-customized port system,utilization of a camera without a separate external light,and instruments with different lengths has brought the favorable environment for SPLS.However,performing SPLS still creates several hardships compared to multiport laparoscopic surgery;a single-port system inevitably leads to clashing of surgical instruments due to crowding.To overcome such difficulties,investigators has developed novel concepts and maneuvers,including the concept of inverse triangulation and the maneuvers of pivoting,spreading out dissection,hanging suture,and transluminal traction.The final destination of SPLS is expected to be a completely seamless operation,maximizing the minimal invasiveness.Specimen extraction through the umbilicus can undermine cosmesis by inducing a larger incision.Therefore,hybrid laparoscopic technique,which combined laparoscopic surgical technique with natural orifice specimen extraction(NOSE)-i.e.,transvaginal or transanal route-,has been developed.SPLS and NOSE seemed to be the best combination in pursuit of minimal invasiveness.In the near future,robotic SPLS with natural orifice transluminal endoscopic surgery’s way of specimen extraction seems to be pursued.It is expected to provide a completely or nearly complete seamless operation regardless of location of the lesion in the abdomen.

Single port laparoscopic liver surgery:A minireview

Nowadays,the trend is to perform surgeries with"scarless"incisions.In light of this,the single-port laparoscopic surgery(SPLS)technique is rapidly becoming widespread due to its lack of invasiveness and its cosmetic advantages,as the only entry point is usually hidden in the umbilicus.The interest in"scarless"liver resections did not grow as rapidly as the interest in other scarless surgeries.Hepatopancreatobiliary surgeons are reluctant to operate a malignant lesion through a narrowincision with limited exposure.There are concerns over adverse oncological outcomes for single-port laparoscopic liver resections(SPL-LR)for hepatocellular carcinoma or metastatic colorectal cancer.In addition,getting familiar with using the operating instruments through a narrow incision with limited exposure is very challenging.In this article,we reviewed the published literature to describe history,indications,contraindications,ideal patients for new beginners,technical difficulty,advantages,disadvantages,oncological concern and the future of SPL-LR.

Technical and instrumental prerequisites for single-port laparoscopic solo surgery:state of art

With the aid of advanced surgical techniques and instruments, single-port laparoscopic surgery(SPLS) can be accomplished with just two surgical members: an operator and a camera assistant. Under these circumstances, the reasonable replacement of a human camera assistant by a mechanical camera holder has resulted in a new surgical procedure termed singleport solo surgery(SPSS). In SPSS, the fixation and coordinated movement of a camera held by mechanicaldevices provides fixed and stable operative images that are under the control of the operator. Therefore, SPSS primarily benefits from the provision of the operator's eye-to-hand coordination. Because SPSS is an intuitive modification of SPLS, the indications for SPSS are the same as those for SPLS. Though SPSS necessitates more actions than the surgery with a human assistant, these difficulties seem to be easily overcome by the greater provision of static operative images and the need for less lens cleaning and repositioning of the camera. When the operation is expected to be difficult and demanding, the SPSS process could be assisted by the addition of another instrument holder besides the camera holder.

Single port laparoscopic right hemicolectomy for ileocolic intussusception

A 36-year-old male was admitted with right lower abdominal pain and diarrhea for more than 3 mo. Colonoscopy and a barium enema study revealed a submucosal tumor over the cecum, but computed tomography showed an ileal lipoma. There was no definitive diagnosis preoperatively, but ileocolic intussusception was noted during surgery. Single port laparoscopic radical right hemicolectomy was performed because intra-operative reduction failed. The histological diagnosis of the resected tumor was lipoma. Single port laparoscopic surgery has recently been proven to be safe and feasible. There are advantages compared with conventional laparoscopic surgery, such as smaller incision wounds, fewer port site complications, and easier conversion. However, there are some drawbacks which need to be overcome, such as difficulties in triangulation and instrument clashing. If there are no contraindications to laparoscopy, single port laparoscopic surgery can be performed safely and should be considered for diagnosis and treatment of intussusception in adults. Here, we report the first case of ileocolic intussusception successfully treated by single port laparoscopic surgery.

Single port laparoscopic right hemicolectomy with D3 dissection for advanced colon cancer

We report the first case of single port laparoscopic right hemicolectomy for advanced colon cancer.An abdominal 3 cm length incision was made via the umbilicus.A small wound retractor and a surgical glove were used as a single port.All soft tissue anterior to the superior mesenteric vein was completely removed and D3 lymph node dissection was achieved.The total operative time was 180 min with minimal blood loss (<50 mL).The size of the tumor was 5 cm×3 cm and its tumor stage was T3N0.Sixty-nine lymph nodes were harvested and none were positive.We believe that single port surgery for colon cancer is a feasible and safe procedure with surgical results comparable to conventional laparoscopic procedures.

Feasibility of single-incision laparoscopic cholecystectomy for acute cholecystitis

AIM: To assess the safety of single-incision laparoscopic cholecystectomy(SILC) for acute cholecystitis.METHODS: All patients who underwent SILC at Sano Hospital(Kobe, Japan) between January 2010 and December 2014 were included in this retrospective study. Clinical data related to patient characteristics and surgical outcomes were collected from medical records. The parameters for assessing the safety of the procedure included operative time, volume of blood loss, achievement of the critical view of safety, use of additional trocars, conversion to laparotomy, intraoperative and postoperative complications, and duration of postoperative hospital stay. Patient backgrounds were statistically compared between those with and without conversion to laparotomy.RESULTS: A total of 100 patients underwent SILC for acute cholecystitis during the period. Preoperative endoscopic treatment was performed for suspected choledocholithiasis in 41 patients(41%). The mean time from onset of acute cholecystitis was 7.7 d. According to the Updated Tokyo Guidelines(TG13) for the severity of cholecystitis, 86 and 14 patients had grade Ⅰ and grade Ⅱ acute cholecystitis, respectively. The mean operative time was 87.4 min. The mean estimated blood loss was 80.6 mL. The critical view of safety was obtained in 89 patients(89%). Conversion laparotomy was performed in 12 patients(12%). Postoperative complications of Clavien-Dindo grade Ⅲ or greater were observed in 4 patients(4%). The mean duration of postoperative hospital stay was 5.7 d. Patients converted from SILC to laparotomy tended to have higher days after onset.CONCLUSION: SILC is feasible for acute cholecystitis; in addition, early surgical intervention may reduce the risk of laparotomy conversion.

Single-incision laparoscopic cecectomy for low-grade appendiceal mucinous neoplasm after laparoscopic rectectomy

In this case report,we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer.The optimal surgical therapy for low-grade appendiceal neoplasm is controversial;currently,the options include appendectomy,cecectomy,right hemicolectomy,and open or laparoscopic surgery.Due to the risk of pseudomyxoma peritonei,complete resection without rupture is necessary.We have encountered 5 cases of lowgrade appendiceal neoplasm and all 5 patients had no lymph node metastasis.We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy.In the present case,we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery(SILS),which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery.We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors,such as low-grade appendiceal neoplasms.

Single-site laparoscopic partial nephrectomy: Where are we going?

AIM:To review an evolution of laparoscopic surgery,there has been a growing interest in laparoendoscopic single-site surgery(LESS).METHODS:A comprehensive electronic literature search was conducted using PubM ed database to identify all publications relating to LESS-partial nephrectomy(PN).The research includes articles published from April 2008 to January 2014.We focused our attention only on articles in which were cited the single-site surgical technique(laparoscopic and robotic),tumour stage and grade,mean tumour size,intraoperative variables,blood loss and transfusion rate,length of postoperative stay and complication rates,Clavien classification,positive of surgical margins,pain assessment at discharge.RESULTS:A total of 9 studies were collected with 221patients included.The mean patients age was 62 years.The mean tumor size was 2.35 cm with a mean operative time of 181 min(range 111-270 min)and 58.3%were done by robot.The mean ischemia time was 23.6min.The 25.8%of patients underwent an unclamp LESS-PN.Mean estimated blood loss was 296 mL and median length of hospital stay was 4 d.The rate of severe post-operative complications(≥Clavien gradeⅢ)was 5.4%.Not all surgical series of LESS-PN or Robotic-LESS-PN shows conversion in Multiport Laparoscopic or Open Surgery.Regarding oncologic outcomes,surgical margins were positive 4%of patients(9/221),no distant or port-site metastases were recorded.CONCLUSION:LESS-PN and RLESS-PN are feasible and associated with reduced postoperative pain,shorter median hospital stay,shorter recovery time,and better cosmetic satisfaction without compromising surgical and oncological safety.

Novel and safer endoscopic cholecystectomy using only a flexible endoscope via single port

AIM: To apply the laparoscopic and endoscopic cooperative surgery concept, we investigated whether endoscopic cholecystectomy could be performed more safely and rapidly via only 1 port or not.METHODS: Two dogs(11 and 13-mo-old female Beagle) were used in this study. Only 1 blunt port was created, and a flexible endoscope with a tip attachment was inserted between the fundus of gallbladder and liver. After local injection of saline to the gallbladder bed, resection of the gallbladder bed from the liver was performed. After complete resection of the gallbladder bed, the gallbladder was pulled up to resect its neck using the Ring-shaped thread technique. The neck of the gallbladder was cut using scissor forceps. Resected gallbladder was retrieved using endoscopic net forceps via a port. RESULTS: The operation times from general anesthetizing with sevoflurane to finishing the closure of the blunt port site were about 50 min and 60 min respectively. The resection times of gallbladder bed were about 15 min and 13 min respectively without liver injury and bleeding at all. Feed were given just after next day of operation, and they had a good appetite. Two dogs are in good health now and no complications for 1 mo after endoscopic cholecystectomy using only a flexible endoscope via one port.CONCLUSION: We are sure of great feasibility of endoscopic cholecystectomy via single port for human.

Single-port versus multi-port cholecystectomy for patients with acute cholecystitis: a retrospective comparative analysis

BACKGROUND: Trans-umbilical single-port laparoscopic cholecystectomy for chronic gallbladder disease is becoming increasingly accepted worldwide. But so far, no reports exist about the challenging single-port surgery for acute cholecystitis. The objective of this study was to describe our experience with single-port cholecystectomy in comparison to the conventional laparoscopic technique. METHODS: Between August 2008 and March 2010, 73 patients with symptomatic gallbladder disease and histopathological signs of acute cholecystitis underwent laparoscopic cholecystec- tomy at our institution. Thirty-six patients were operated on with the single-port technique (SP group) and the data were compared with a control group of 37 patients who were treated with the multi-port technique (MP group). RESULTS: The mean age in the SP group was 61.5 (range 21-81) years and in the MP group was 60 (range 21-94) (P=0.712). Gender, ASA status and BMI were not significantly different. The number of white blood cells was different before [SP: 9.2 (range 2.8-78.4); MP: 13.2 (range 4.4-28.6); P=0.001] and after the operation [SP: 7.8 (range 3.5-184.8); MP: 11.1 (range 5-20.8); P=0.002]. Mean operating time was 88 (range 34-174) minutes in the SP group vs 94 (range 39-209) minutes in the MP group (P=0.147). Four patients (5%) required conversion to an open procedure (SP: 1; MP: 3; P=0.320). During the follow- up period of 332 (range 29-570) days in the SP group and 428 (range 111-619) days in the MP group (P=0.044), eleven (15%) patients developed postoperative complications (P=0.745) and two patients in the SP group required reoperation (P=0.154). CONCLUSIONS: Trans-umbilical single-port cholecystectomy for beginning acute cholecystitis is feasible and the complicationrate is comparable with the standard multi-port operation. In spite of our good results, these operations are difficult to perform and should only be done in high-volume centers for laparoscopic surgery with experience in single-port surgery.

Present laparoscopic surgery for colorectal cancer in Japan

In many clinical studies,laparoscopic surgery(LS) for colon cancer has been shown to be less invasive than open surgery(OS) while maintaining similar safety.Furthermore,there are no significant differences between LS and OS in long-term outcomes.Thus,LS has been accepted as one of the standard treatments for colon cancer.In the treatments of rectal cancer as well,LS has achieved favorable outcomes,with many reports showing long-term outcomes comparable to those of OS.Furthermore,the magnification in laparoscopy improves visualization in the pelvic cavity and facilitates precise manipulation,as well as providing excellent educational effects.For these reasons,rectal cancer has seemed to be well indicated for LS,as has been colon cancer.The indication for LS in the treatment of locally advanced rectal cancer,which is relatively unresectable(e.g.,cancer invading other organs),remains an open issue.In recent years,new techniques such as singleport and robotic surgery have begun to be introduced for LS.Presently,various clinical studies in our country as well as in most Western countries have demonstrated that LS,with these new techniques,are gradually showing long-term outcomes.

Single Port Transumbilical Laparoscopic Surgery versus Conventional Laparoscopic Surgery for Benign Adnexal Masses： A Retrospective Study of Feasibility and Safety

Background： Single port laparoscopic surgery （SPLS） is an innovative approach that is rapidly gaining recognition worldwide. The aim of this study was to determine the feasibility and safety of SPLS compared to conventional laparoscopic surgery for the treatment of benign adnexal masses. Methods： In total, 99 patients who underwent SPLS for benign adnexal masses between December 2013 and March 2015 were compared to a nonrandomized control group comprising 104 conventional laparoscopic adnexal surgeries that were performed during the same period. We retrospectively analyzed multiple clinical characteristics and operative outcomes of all the patients, including age, body mass index, size and pathological type of ovarian mass, operative time, estimated blood loss （EBL）, duration of postoperative hospital stay, etc. Results： No significant difference was observed between the the pathological results between the two groups were found to two groups regarding preoperative baseline characteristics. However, be slightly different. The most common pathological type in the SPLS group was mature cystic teratoma, whereas endometrioma was more commonly seen in the control group. Otherwise, the two groups had comparable surgical outcomes, including the median operation time （51 min vs. 52 min, P = 0.909）, the median decreased level of hemoglobin from preoperation to postoperation day 3 （10 g/L vs. 10 g/L, P = 0.795）, and the median duration of postoperative hospital stay （3 days vs. 3 days, P = 0.168）. In SPLS groups, the median EBL and the anal exsufftation time were significantly less than those of the conventional group （5 ml vs. 10 ml, P〈 0.001; 10 h vs. 22 h, P〈 0.001）. Conclusions： SPLS is a feasible and safe approach for the treatment of benign adnexal masses. Further study is required to better determine whether SPLS has significant benefits compared to conventional techniques.
