Supplementary Material
- Complete mesocolic excision and central vascular ligation with D3 lymphadenectomy are important surgical principles for improving oncological outcomes in colon cancer. The cranial-first approach is a colonic mobilization–first approach to radical right hemicolectomy, which has several advantages, including early feasibility assessment, safe dissection from surrounding organs, preestablished inferior margin of lymph node dissection, and revelation of the tangible anatomy of the tributaries of the gastrocolic trunk. This video demonstrates the cranial-first approach to radical right hemicolectomy in a 66-year-old man with locally advanced cecal cancer.

Abstract
PDF
- One of the possible causes of chronic constipation is colonic duplication. Although seldom asymptomatic, its diagnosis is important due to the risk of malignancy that it carries. We present a case of a young female patient with long-standing constipation who was referred to Kolorektal Cerrahi Clinic (Izmir, Turkey) after scans revealed tubular type of colonic duplication. We successfully performed a laparoscopic total colectomy, and she recovered well. Identifying the type of duplication is important to ensure adequate resection and treatment. A proper workup, including carcinoembryonic antigen levels, must be done as well. Multiple surgical techniques and procedures have been introduced for this condition, but resection of the duplicated colon with its native lumen should be the management of choice, especially in tubular type of duplications such as in our case. In centers where laparoscopic services are available, laparoscopy could be a better option, as it provides multiple benefits of minimally invasive surgery. Attention should also be paid to anatomical details during surgery to ensure better results and outcomes.

Abstract

- Purpose
Since the introduction of robotic surgery, robots for colorectal cancer have replaced laparoscopic surgery, and a single-port robot (SPR) platform has been launched and is being used to treat patients. We analyzed the learning curve and initial complications of using an SPR platform in colorectal cancer surgery.
Methods
We reviewed 39 patients who underwent SPR colectomy from April to October 2019. All surgeries were performed by the same surgeon using an SPR device. A learning curve was generated using the cumulative sum methodology to assess changes in total operation time, docking time, and surgeon console time. We grouped the patients into 3 groups according to the time period: the first 11 were phase 1, the next 11 were phase 2, and the last 17 were phase 3.
Results
The mean age of the patients was 61.28±13.03 years, and they had a mean body mass index of 23.79±2.86 kg/m2. Among the patients, 23 (59.0%) were male, and 16 (41.0%) were female. The average operation time was 186.59±51.30 minutes, the average surgeon console time was 95.49±35.33 minutes, and the average docking time (time from skin incision to robot docking) was 14.87±10.38 minutes. The surgeon console time differed significantly among the different phases (P<0.001). Complications occurred in 8 patients: 2 ileus, 2 postoperation hemoglobin changes, 3 urinary retentions, and 1 complicated fluid collection.
Conclusion
In our experience, the learning curve for SPR colectomy was achieved after the 18th case.

Abstract

- Purpose
Surgical management of obstructive left colon cancer (OLCC) is still a matter of debate. The classic Hartmann procedure (HP) has a disadvantage that requires a second major operation. Subtotal colectomy/total abdominal colectomy (STC/TC) with ileosigmoid or ileorectal anastomosis is proposed as an alternative procedure to avoid stoma and anastomotic leakage. However, doubts about morbidity and functional outcome and lack of long-term outcomes have made surgeons hesitate to perform this procedure. Therefore, this trial was designed to provide data for morbidity, functional outcomes, and long-term outcomes of STC/TC.
Methods
This study retrospectively analyzed consecutive cases of OLCC that were treated by STC/TC between January 2000 and November 2020 at a single tertiary referral center. Perioperative outcomes and long-term outcomes of STC/TC were analyzed.
Results
Twenty-five descending colon cancer (45.5%) and 30 sigmoid colon cancer cases (54.5%) were enrolled in this study. Postoperative complications occurred in 12 patients. The majority complication was postoperative ileus (10 of 12). Anastomotic leakage and perioperative mortality were not observed. At 6 to 12 weeks after the surgery, the median frequency of defecation was twice per day (interquartile range, 1–3 times per day). Eight patients (14.5%) required medication during this period, but only 3 of 8 patients required medication after 1 year. The 3-year disease-free survival was 72.7% and 3-year overall survival was 86.7%.
Conclusion
The risk of anastomotic leakage is low after STC/TC. Functional and long-term outcomes are also acceptable. Therefore, STC/TC for OLCC is a safe, 1-stage procedure that does not require diverting stoma.

Abstract

- Purpose
Laparoscopic right hemicolectomy (LRH) can be performed with an intracorporeal anastomosis (IA) or extracorporeal anastomosis (EA). It is not clear which technique is best. This study evaluated the impact of each anastomosis technique on perioperative safety and postoperative evolution.
Methods
We performed a retrospective study at a tertiary colorectal surgery center. All patients who had an elective LRH from 2015 to 2019 were analyzed according to the anastomosis technique used.
Results
In total, 285 patients were included in the study. IA was performed in 64 patients (22.5%). Mean operative time was longer in the patients with IA (IA, 160±31 minutes vs. EA, 138±42 minutes; P<0.001). No differences were observed in intraoperative complications, time to first bowel movement, length of stay, reoperation, or rehospitalization. Time to first flatus was longer in the patients with IA (P=0.049). At 30 days after surgery, there were no differences in the frequency of anastomotic leak (IA, 0% vs. EA, 2.3%; P=0.59), bleeding (IA, 3.1% vs. EA, 2.7%; P>0.99), or intraabdominal abscess (IA, 0% vs. EA, 0.5%; P>0.99). During follow-up, we noted more incisional hernias in patients with EA (IA, 1.6% vs. EA, 11.3%; P=0.01) and a trend toward more hernia in patients with EA in multivariate analysis (hazard ratio, 7.13; P=0.06). Anastomosis technique had no influence on recurrence.
Conclusion
For LRH, both IA and EA are safe, with a low incidence of complications when performed by experienced surgeons. IA may be associated with a lower incidence of incisional hernia.

Abstract
PDF
- Colon cancer treatment is on the way to evolution over several decades. The minimally invasive surgery has improved postoperative short-term outcomes. Adjuvant chemotherapy has prolonged the survival of advanced colon cancer patients. Hohenberger proposed the noble concept of complete mesocolic excision (CME) which consists of 3 components: plane surgery, sufficient longitudinal bowel resection, and central vascular ligation (CVL). Mesocolic plane surgery shares the same surgical principle of total mesorectal excision, which is maintaining the intact mesothelial envelope. However, there remain debates about the extent of bowel resection and the level of CVL for maximizing lymph node dissection. There is no solid clinical evidence for the oncological necessity and benefit of extended radical dissection in right hemicolectomy. CME with CVL based on open surgery has been adopted in laparoscopic surgery. So, it is also necessary to look at how the CME could be transformed and successfully implanted in the laparoscopic era. Recent rapid advances in surgical technology and cancer biology are preparing for fundamental changes in cancer surgery. In this study, we reviewed the history, oncological necessity, and compatibility of CME for the right hemicolectomy in the laparoscopic era and outline the new perspectives on the evolution of cancer surgery.

- Intussusception involving the colon is unusual in adults and when present is managed with resection due to the risk of malignancy. We present an unusual case where the intussusceptum was impacted stool in a mucosal pouch in the transverse colon. The patient presented with bleeding per rectum and abdominal pain and was found to have a colocolic intussusception on computed tomography. Colonoscopy showed an ulcerated mass in the transverse colon. A laparoscopic right hemicolectomy was performed. Histopathology demonstrated known chronic lymphocytic leukemia, but not solid malignancy. A large fecalith impacted within a mucosal pouch had acted as the lead point. This represents a highly unusual but benign cause of intussusception.

- Purpose
The minimum harvested 12 lymph nodes (LNs) is regarded as the limit for accurate staging of nodal status in colorectal cancer patients. Besides the association of the lengths of resected intestinal segments and vascular pedicles, the mesocolic mesenteric area’s impact on LN count has not been studied. We aimed to evaluate the associations between metric variables, including the mesocolic mesentery area on the nodal harvest.
Methods
All consecutive patients who underwent elective colectomy with a curative intention for colon adenocarcinoma were prospectively included. The metric variables included the lengths of resected intestinal segments, vascular pedicle, and colonic mesenteric area. The variables influencing the LN count and the correlation between the total LN count and the specimens’ relevant metric measurements were analyzed.
Results
There were 46 patients with a median age of 64 years. The median count for total LNs was 22, and the LN positivity was 59.2%. There was an inadequate LN yield (<12) in 3 patients (6.1%). No significant associations were found between the adequacy of nodal harvest and the demographic, clinical, and tumoral features (P>0.05). There were significant positive correlations between total LN number and length of vascular pedicle and mesenteric area (r=0.576, P<0.001 and r=0.566, P<0.001).
Conclusion
The length of the vascular pedicle and mesenteric area were significantly correlated with total LN counts. Although there was no significant impact on the length of resected segments, the colonic mesenteric area can be used alone as a measure for the assessment of the nodal yield in colon cancer.

Abstract
PDF
- Malakoplakia is a rare granulomatous inflammatory disorder. Its diagnosis depends on histopathological findings; however, high-quality literature regarding proper medical/surgical treatment is lacking. A 38-year-old diabetic female patient was admitted to the emergency room with a history of lower gastrointestinal hemorrhage. Colonoscopy revealed a lesion in the descending colon, and abdominal computed tomography revealed a splenic flexure mass involving the lower pole of the spleen and upper pole of the left kidney. Biopsies confirmed the diagnosis of malakoplakia. After completing antibiotic treatment, a restaging computed tomography revealed a discrete mass increase; hence, the patient underwent laparoscopic en bloc colectomy and partial nephrectomy. Postoperatively, the patient developed a pancreatic fistula, which was successfully treated with percutaneous drainage and antibiotics. The presence of pathognomonic Michaelis-Gutmann inclusions on histopathology is frequently reported as the key to diagnosing malakoplakia. Herein, we present a successful, minimally invasive surgical treatment for colonic malakoplakia.

- Purpose
Laparoscopic approach to colonic tumor requires skill set and resources to be established as routine standard of care in most centers around the world. It presents particular challenge in country like Pakistan due to economic constrain and lack of teaching and training opportunities available for surgeons to be trained to deliver such service. The aim of this study is to look into changing practice of our institution from conventional approach of open to laparoscopic surgery for right colon cancer.

Consecutive patients between January 2010 to December 2018 who presented to Shaukat Khanum Memorial Cancer Hospital and Research Centre with diagnosis of right colon (cecum, ascending and transverse colon) adenocarcinoma and underwent surgical resections were included in this study.
Results
A total of 230 patients with adenocarcinoma of the right colon underwent curative resections during the study period. Of these, 141 patients (61.3%) underwent laparoscopic surgery while open resection was performed in 89 patients (38.7%). Five-year disease-free survival (DFS) of patients with American Joint Committee on Cancer (AJCC) stage III (80.9% vs. 54.8%, P = 0.021) was significantly better if these patients underwent laparoscopic surgery while a trend toward better DFS (96.7% vs. 84.1%, P = 0.111) was also observed in AJCC stage II patients, although this difference was not significant.
Conclusion
This study demonstrates the adoption of a laparoscopic approach for right colon cancer over 10 years. With a standardized approach and using the principle of oncological surgery, we incorporated this in our minimally invasive surgery practice at our institution.

Abstract
PDF
- Purpose
Laparoscopic complete mesocolic excision (CME) right colectomy is a technically demanding procedure infrequently employed in Western centers. This retrospective cohort study aims to analyze the safety of laparoscopic CME colectomy compared to standard colectomy for right-sided colon cancer in a Western series.
Methods
Prospectively collected data from 60 patients who underwent laparoscopic CME right colectomy were compared to the ones of 55 patients who underwent laparoscopic standard right colectomy.
Results
No differences in clinical characteristics were observed between the CME and standard right colectomy groups. No differences were demonstrated in terms of blood loss (P = 0.060), intraoperative complications (P = 1), conversion rate (P = 0.102), and operative time (P = 0.473). No deaths were observed in either group, while complication rate was 40.0% in the CME and 49.1% in the standard group (P = 0.353). Severe complications occurred in 10.0% vs. 9.1% (P = 0.842), redo surgery in 5.0% vs. 7.3% (P = 0.708), and unplanned readmission in 5.0% vs. 5.5% (P = 1) after CME and standard colectomy, respectively. A significant difference in favor of CME was observed in the total length of specimen (P < 0.001), proximal (P = 0.018), and distal margins (P = 0.037). The number of lymph nodes harvested was significantly higher in the CME group (27 vs. 22, P = 0.037).
Conclusion
In Western series, where patients have less favorable clinical characteristics, laparoscopic CME allows to obtain better quality surgical specimens and comparable short-term outcomes compared to standard right colectomy.

Abstract
PDF
- Purpose
Anastomotic leak (AL) after a low pelvic anastomosis is a devastating complication, with short- and long-term morbidity and increased mortality. Surgeons may employ various adjuncts in an attempt to reduce AL rates or mitigate their impact. These include the use of temporary diverting ileostomy (TDI), transanal or rectal tubes and pelvic drains. This questionnaire evaluates the preferences and routine use of these adjuncts in Australasian colorectal surgeons.
Methods
A cross-sectional survey was administered to Australian and New Zealand colorectal surgeons on September 20, 2018. The study survey consisted of 15 questions exploring basic demographics and the number of rectal resections and ileal pouches performed in 12 months, along with the surgeon’s preference for the use of diverting stomas, rectal tubes, and pelvic drains.
Results
There were 90 respondents to the survey (31.6%). Surgeons in Western Australia (71.4%) were more likely to use a mandatory TDI in colorectal extraperitoneal anastomoses than surgeons in Queensland (14.3%). South Australian surgeons are more likely to employ a mandatory TDI (100%) for ileal pouches than Queensland surgeons (42.9%). Rectal tubes are not commonly utilized (40.0% never use them), and pelvic drains are (45.6% in all cases). Surgeons consider a median AL rate of 15% was felt to justify the use of a TDI in low pelvic anastomoses and a median AL rate of 10% for ileal pouches
Conclusion
There is considerable geographical variation in colorectal surgical practice throughout Australia and New Zealand. While surgeons interrogate the same literature, there are presumably other factors that see translation into variations in clinical practice.

Abstract
PDF
- Purpose
This study aimed to compare the short-term outcomes of the open and laparoscopic approaches to 2-stage restorative proctocolectomy (RPC) for Korean patients with ulcerative colitis (UC).
Methods
We retrospectively analyzed the medical records of 73 patients with UC who underwent elective RPC between 2009 and 2016. Patient characteristics, operative details, and postoperative complications within 30 days were compared between the open and laparoscopic groups.
Results
There were 26 cases (36%) in the laparoscopic group, which had a lower mean body mass index (P = 0.025), faster mean time to recovery of bowel function (P = 0.004), less intraoperative blood loss (P = 0.004), and less pain on the first and seventh postoperative days (P = 0.029 and P = 0.027, respectively) compared to open group. There were no deaths, and the overall complication rate was 43.8%. There was no between-group difference in the overall complication rate; however, postoperative ileus was more frequent in the open group (27.7% vs. 7.7%, P = 0.043). Current smoking (odds ratio [OR], 44.4; P = 0.003) and open surgery (OR, 5.4; P = 0.014) were the independent risk factors for postoperative complications after RPC.
Conclusion
Laparoscopic RPC was associated with acceptable morbidity and faster recovery than the open approach. The laparoscopic approach is a feasible and safe option for surgical treatment for UC in selective cases.
