Lending a hand: The utility of hand-assisted laparoscopic surgery in diverticulitis with fistula

BackgroundCurrent guidelines recommend elective colectomy for the management of diverticulitis-associated fistulas. These cases present considerable operative challenges, and surgical approaches and fistula tract management vary widely. Hand-assisted laparoscopic surgery offers the benefits of minimally invasive surgery while maintaining the tactile advantages of open surgery. This study aims to evaluate outcomes of hand-assisted laparoscopic surgery colectomy for diverticulitis-associated fistulas, fistula tract, and urinary catheter management. MethodsA retrospective review of patients with diverticulitis-associated fistula who underwent elective hand-assisted laparoscopic surgery colectomy between January 2, 2008, and September 8, 2022, was performed. Patients with Crohn disease or who underwent emergency surgery were excluded. ResultsSeventy patients were included; the mean patient age was 64.1 ± 14.8 years, and the mean body mass index was 30.9 ± 9.1 kg/m2. Colovesical fistulas were most common (n = 48; 68.6%), followed by colovaginal fistulas (n = 22; 31.4%). The median operative time was 186 minutes. Conversion to an open approach occurred in 4 cases (5.7%). The fistula tract remnant was left without intervention in 35 patients (50%), and omental coverage occurred in 23 cases (32.9%). The median duration of the urinary catheter was 3 days (range = 1–63). There were no postoperative urine leaks. Three patients (4.3%) were readmitted in ≤30 days. There were no 30-day mortalities. ConclusionThe challenges of colectomy for diverticulitis-associated fistulas can be mitigated using the hand-assisted laparoscopic surgery technique. We found a low conversion-to-open rate, falling below rates reported for laparoscopic colectomy. There were no cases of postoperative urine leak, suggesting that no intervention or omental coverage is a safe approach to fistula tract management.

Crohn’s disease-related anal fistula cancer diagnosed by examination under anesthesia: a case report

BackgroundAs the number of patients with inflammatory bowel disease (IBD) increases, the incidence of IBD-related colorectal cancer (CRC) is also on the rise. Crohn’s disease (CD)-related CRC has been reported to have a poorer prognosis than sporadic CRC, and the early detection of CD-related CRC is difficult. Japanese patients with CD are reported to have a higher frequency of anorectal cancer than the Western population; however, methods for early diagnosis have not yet been established because of perianal pain during the examination.Case presentationWe report a case of CD-related anal fistula cancer that was detected early by surveillance examination under anesthesia (EUA). The patient was a 37-year-old man, diagnosed with CD at the age of 15 years and started medical treatment. However, due to poor disease control, the intestinal tract remained highly inflamed and the patient continued to have over 10 bowel movements per day. He was referred to our hospital for surgical treatment after a colonoscopy (CS), which revealed multiple active ulcers and stenoses. Since three perianal seton drainage tubes had been placed around his anus since the age of 33 years, we decided to perform an EUA to rule out cancer coexistence in the anorectal region. After a random biopsy of the rectum by CS under general anesthesia, we resected and curetted multiple perianal fistulas as much as possible and reinserted the seton drainage tubes. Pathological examination of the fistula tract revealed adenocarcinoma in one tract, indicating the coexistence of anal fistula cancer. Based on the diagnosis of multiple intestinal stenoses and anal fistula cancer due to CD, we performed hand-assisted laparoscopic total colectomy, rectal amputation, extensive perineal resection, and reconstruction using a left rectus abdominis flap.ConclusionIn a long-term CD patient with anorectal lesions, we performed an EUA to diagnose the coexistence of anal fistula cancer at an early stage, and surgical resection was achieved. EUA is effective for the early detection and treatment of CD-related CRC and may contribute to an improved prognosis.

High Rates of Incisional Hernia After Laparoscopic Right Colectomy With Midline Extraction Site.

Laparoscopic surgery aims at reducing wound complications and improving cosmetics, among other advantages. High rates of postoperative ventral hernia (POVH) are observed after laparoscopic-assisted colectomies. In a 2011 to 2016 retrospective study of all patients at Rabin Medical Center, we examined POVH prevalence after right hemicolectomy for neoplasia and correlation to specimen extraction site. We also compared laparoscopic-assisted colectomy to hand-assisted laparoscopic colectomy. Included were patients who had postoperative abdominal computed tomography or magnetic resonance imaging scan as part of their routine oncological follow-up to 6 months postsurgery. Patients were excluded for conversion to laparotomy, and prior abdominal surgeries after right colectomy and before follow-up computed tomography/magnetic resonance imaging scan. Demographic and surgical data were collected from patient electronic records, and scans reviewed for POVH by a designated radiologist. Of 370 patients, 138 (mean age 70.09 y, 58 males) were included: 54 (39.1%) were diagnosed with POVH, 42/72 (58.3%) at midline extraction site, and 12/66 (18.8%) at off-midline extraction sites (P<0.0001). Surgical site infections and patients positive for tumor metastasis were associated with higher POVH rates. Most (74%) POVHs were identified within 18 months postsurgery (P<0.0001). Body mass index, age, sex, diabetes mellitus, smoking, tumor size, lymph nodes positive for metastasis, and hand-assisted laparoscopic colectomy were not associated with POVH prevalence. High rates of radiologically diagnosed POVH were found after laparoscopic-assisted colectomy, with association to midline extraction site, surgical site infections, and positive tumor distant metastasis.

Effect of LncRNA MIAT on Prognosis of Hand-assisted Laparoscopic or Laparoscopic-assisted Colectomy for Colorectal Cancer.

The current study aims to explore the effect of myocardial infarction associated transcript (MIAT) level on the long-term prognosis of hand-assisted laparoscopic colectomy (HALC) or laparoscopic-assisted colectomy (LAC) for colorectal cancer (CC). A total of 320 CC patients were included. Patients were randomized into HALC and LAC group. MIAT level in CC tissue was upregulated, and had a significant positive association with its level in serum. MIAT levels in both CC tissue and serum were correlated with lymph node metastasis and histologic grading. Survival analysis showed that the overall survival rate in 3 years after operation was significantly lower in HALC-High MIAT group (P<0.05). When MIAT level is <10.9 in CC tissue or 8.7 in serum, 100% of patients who underwent HALC will be alive for >3 years. For patients with low MIAT level, both HALC and LAC are available, otherwise, LAC is more recommended.

Retroileal anastomosis in hand-assisted laparoscopic left colectomy: experience at a single institution

Left hemicolectomy and complicated sigmoid colectomy require an anastomosis between the transverse colon and rectum. Generous mobilization will typically allow the colon to reach to the rectum. However, despite full mobilization of the splenic flexure and extensive work on the mesentery, there are cases in which reach to the pelvis is still an issue. Retroileal routing of the colon is one technique for overcoming such a reach problem and achieving a tension-free anastomosis. Performing retroileal routing using laparoscopic techniques has been reported rarely, and to date, there are no data on this technique when performed in a hand-assisted laparoscopic fashion. This study aimed to describe the feasibility of doing a retroileal routing using a hand-assisted laparoscopic technique. This was a retrospective chart review of patients who underwent a colon or rectal resection, either open or laparoscopic, with a pelvic anastomosis, by a single colorectal surgeon at an academic institution between 2008 and 2015 with a focus on the immediate and long-term postoperative complications, estimated blood loss, and operating room time for patients having an operation that included retroileal routing for construction of a colorectal anastomosis. A total of 340 patients fit inclusion criteria and of these, 13 underwent hand-assisted laparoscopic procedures with retroileal routing of the proximal colon to the colorectal anastomosis. Postoperative morbidity included intubation for CO2 retention in one patient and a RLL effusion in another patient; there were no anastomotic leaks. Long-term morbidities included two ventral hernias at 2years postoperatively. Mean operating room time was 208min. There were no 30- or 90-day mortalities. Hand-assisted laparoscopic retroileal routing is a feasible and safe technique in accomplishing a tension-free colorectal anastomosis when proximal colon length makes standard routing of the colon to the rectum an issue.

Hand-Assisted Laparoscopic Colectomy Improves Perioperative Outcomes Without Increasing Operative Time Compared to the Open Approach: a National Analysis of 8791 Patients

IntroductionHand-assisted laparoscopic surgery (HALS) is often used in procedures too complex for completely minimally invasive approaches. However, there are concerns for whether this hybrid approach abrogates perioperative benefits of the completely minimally invasive technique. MethodsWe queried the 2012–2013 National Surgery Quality Improvement Program for adults undergoing elective HALS or open colectomy (OC). After propensity matching, short-term outcomes were compared. Subset analysis was performed for segmental resections. Multivariate analysis was used to determine predictors of utilizing either approach. ResultsThis query included 8791 patients (OC 2707, HALS 6084). Predictors of HALS included male sex (OR 1.17, p = 0.006), increasing BMI (OR 1.01, p = 0.02), benign indication (OR 1.48, p < 0.001), and total abdominal colectomy (OR 10.39, p < 0.001). Younger age, black race, ASA class ≥3, inflammatory bowel disease, and low pelvic anastomosis were predictive of OC (all p < 0.05). HALS demonstrated reduced overall complications (p < 0.001), wound complications (p < 0.001), anastomotic leak (p = 0.014), transfusion (p < 0.001), postoperative ileus (p < 0.001), length of stay (p < 0.001), and readmission (p < 0.001) without increased operative time. For segmental resection, HALS demonstrated reduced overall complications, wound complications, respiratory complications, postoperative ileus, anastomotic leak, transfusion, length of stay, and readmissions (all p < 0.05). ConclusionsCompared to OC, HALS demonstrates improved perioperative outcomes without increased operative time.

Hand-assisted laparoscopic vs open colectomy: an assessment from the American College of Surgeons National Surgical Quality Improvement Program procedure-targeted cohort

BackgroundPerioperative outcomes of patients who underwent hand-assisted colorectal laparoscopic (HALS) vs open colectomy were compared using recently released procedure-targeted database. MethodsReview was conducted using the 2012 colectomy-targeted American College of Surgeons National Surgical Quality Improvement Program database. Patients were classified into 2 groups according to final surgical approach: HALS vs open (planned). Groups were matched (1:1) based on age, gender, body mass index, surgical procedure, diagnosis, American Society of Anesthesiologists score, and wound classification. Multivariate logistic regression analysis was conducted for group comparison. ResultsOf 7,303 patients, 1,740 patients were matched in each group. Open group had higher proportion of patients with preoperative dyspnea (P = .01), ascites (P = .01), weight loss (P < .001), smoking history (P = .04), and increased work relative value units (P < .001). After adjusting for difference in baseline comorbidities, overall morbidity, superficial, deep, and organ-space surgical site infection, urinary tract infection, ileus, reoperation, readmission, and hospital stay were significantly higher in open group (P < .05). ConclusionsNational Surgical Quality Improvement Program targeted-data demonstrated several advantages of HALS compared with open colonic resection including shorter hospital stay and lower complication rate. Further adoption of HALS technique as a bridge to straight laparoscopy or tool in difficult cases can positively impact the short-term outcomes after colectomy when compared with open technique.

Comparison of straight vs hand-assisted laparoscopic colectomy: an assessment from the NSQIP procedure-targeted cohort

BackgroundThe perioperative outcomes of patients who underwent straight laparoscopic (LAP) vs hand-assisted laparoscopic (HALS) surgery were compared using a recently released procedure-targeted database. MethodsThe 2012 colectomy-targeted American College of Surgeons National Surgical Quality Improvement Program database was used and patients were classified into 2 groups according to the final surgical approach: LAP vs HALS. Demographics, comorbidities, and 30-day outcomes were compared. ResultsA total of 7,843 patients met the inclusion criteria. There were 4,656 (59%) patients in LAP colectomy and 3,187 (41%) in HALS colectomy groups. Groups were comparable in terms of preoperative characteristics and demographics. Mean operative time was slightly longer in LAP group (178 ± 86 vs 171 ± 84 minutes, P < .001). After covariate-adjustment analysis, the overall morbidity, superficial surgical site infection, and ileus rates remained slightly higher in HALS group. ConclusionsBoth straight laparoscopic and hand-assisted approaches are used in colorectal surgery and may complement each other in challenging cases. Implementing the best approach to decrease postoperative complication rates and increase use of minimally invasive techniques may play a role in improving patient care and overall quality.

Hand-Assisted Laparoscopic Approach in Colon Surgery

BackgroundThis study sought to compare outcomes of patients who underwent hand-assisted laparoscopic (HAL) colectomy with open and laparoscopic colectomy (LP). Study DesignThe NSQIP databases were used to examine the clinical data of patients who underwent elective colectomy during 2012–2013. Multivariate regression analysis was performed to compare the three surgical approaches. ResultsWe sampled a total of 21,090 patients who underwent colectomy. Of these, 7480 (35.5 %) had open colectomy (OC), 8751 (41.5 %) had a laparoscopic colectomy, 2860 (13.6 %) had a HAL colectomy, and 1999 (9.5 %) had an open procedure converted from LC or HAL. Multivariate regression analysis revealed HAL colectomy had a similar mortality (AOR 0.53, P = 0.07) and a lower morbidity (AOR 0.37, P < 0.01) compared to OC. LC had lower mortality (AOR 0.58, P = 0.02) and morbidity (AOR 0.43, P < 0.01) compared to OC. Mortality of patients who underwent HAL was not significantly different from LC (AOR 0.90, P = 0.79); however, morbidity of such patients was significantly higher than for patients who underwent LC (AOR 1.29, P < 0.01). ConclusionsHAL colectomy is a safe approach with significant advantages compared to open colectomy. Although the morbidity of patients who underwent HAL is higher than patients who underwent LC, the morbidity rate is still lower than OC.

Functional and clinical outcomes of hand-assisted laparoscopic colorectal surgery: a single-institution experience in 255 patients

Hand-assisted laparoscopic colectomy is an alternative technique to laparoscopy: it is technically easier, learning curve and operative time is shorter. We aimed to describe the characteristics of patients admitted due to colorectal cancer for hand-assisted laparoscopic surgery (HALS), intra- and postoperative clinical and functional outcomes. A prospectively maintained database was used to identify all patients who underwent HALS for colorectal cancer at the National Cancer Institute from April 2006 to November 1 2014. Data are presented as frequency (proportion) or median (interquartile range). A total of 255 HALS colorectal resections were performed. The mean HALS time was 105 min (50–270). The conversion rate was 1.96 % (5/255). The average number of lymph nodes harvested was 15 (2–54). The average time to first flatus was 1.92 days (1.5–4.5), to tolerance of solid food was 2.85 (1.4–3.4), and to first bowel movements was 3.64 (2.6–4.3). The median length of hospital stay was 6.8 days (3–31). Postoperative complication rate was 9.8 %. Three patients (1.17 %) demanded explorative laparotomy. Postoperative mortality rate was 0.39 % (one patient). There was 3.2 % of local recurrence in the colon and 5.8 % in the rectum and no port site metastasis during 36.3 (1–108) months of surveillance. The 3-year survival rates were 100 % for stage I, 97 % for stage II, 84 % for stage III, and 50 % for stage IV colorectal cancer. Hand-assisted laparoscopic colorectal resection preserves nearly all the benefits of laparoscopic colectomy reported in the literature. With experience, it is associated with improved clinical outcomes.

Hand-assisted Laparoscopic Colectomy for Colovesical Fistula Associated With Diverticular Disease

To evaluate the feasibility and short-term outcome of hand-assisted laparoscopic colectomy (HALC) for the treatment of colovesical fistula complicating diverticulitis, we reviewed the files of all 34 patients who underwent surgery for diverticular colovesical fistula in 1999 to 2010 at a major tertiary medical center. Twenty-one were treated with HALC and 13 with open colectomy. There were no differences in demographic parameters among the groups. HALC and open colectomy had similar operating time. HALC was associated with a significantly shorter hospital stay compared with open colectomy (5 vs. 8 d, P=0.001). HALC proved to be technically feasible and safe in this setting. It provided benefits of tactile feedback and manual manipulation as in open colectomy while maintaining the advantages of a minimal invasive approach.

Quality of life after laparoscopic colectomy for cancer.

Background and Objectives:This review focuses on health-related quality-of-life (HRQoL) assessment questionnaires and the influence of various parameters on HRQoL at distinct time points after laparoscopic colectomy for cancer.Methods:A PubMed electronic database literature search was conducted.Results:Twenty studies (7 prospective randomized, 5 nonrandomized, 2 retrospective, 1 matched, and 3 observational studies) used the following HRQoL tools: European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ)–C30 (8 studies), EORTC QLQ-CR38 (6 studies), EORTC QLQ-CR29 (1 study), Short Form 36 (8 studies), Gastrointestinal Quality Life Index (2 studies), EuroQoL-5D (1 study), Symptoms Distress Scale (2 studies), Quality of Life Index (2 studies), and global quality of life (1 study). Long-term beneficial effects on patient HRQoL after laparoscopic colectomy for cancer have not been clearly shown compared with “open” resections. A physical function deterioration and emotional function improvement are observed during the first month. Most patients have recovered at 12 months. Distinct HRQoL domains may be affected in older, female, and chemotherapy-treated patients. HRQoL-related parameters of pain and cosmesis have been assessed in few of the current studies on hand-assisted and single-incision laparoscopic colectomy.Conclusion:Studies' heterogeneity in terms of assessment tools and time points remains as the main obstacle to establish robust conclusions. The addition of more patients and extension of the follow-up period will improve our knowledge on HRQoL changes after laparoscopic colectomy for cancer.

Minimally Invasive Colorectal Surgery in the Morbidly Obese: Does High Body Mass Index Lead to Poorer Outcomes?

Background: Obesity is associated with increased surgical risk and major abdominal procedures performed in morbidly obese patients may prove challenging when compared with normal weight patients. There are limited data regarding outcomes after minimally invasive colorectal surgery in morbidly obese patients. The aim of this study was to compare the outcomes between morbidly obese and normal weight patients. Materials and Methods: Forty morbidly obese were matched to three normal weight patients (n=120), based on type of surgical approach and procedure. The patients underwent minimally invasive colorectal surgery by one of two colorectal surgeons. Patients were considered morbidly obese or normal-weight based on body mass index. Demographic data and operative outcomes were compared. Results: Mean body mass index differed significantly between the morbidly obese (median 43.9 kg/m2) and normal weight (median 22.7 kg/m2) groups, p<0.00001. Both groups were comparable in regards to age, gender, history of prior abdominal operations, and clinical diagnosis. Surgical approaches included multiport laparoscopic colectomy (47.5%), hand-assisted laparoscopic colectomy (35%), robotic-assisted laparoscopic colectomy (12.5%), and single-incision laparoscopic colectomy (5%). The most common procedures were anterior resection (42.5%) and right hemicolectomy (40%). Morbidly obese patients required a significantly longer operative time (median 199 min vs. 139 min, p=0.0004) and resulted in significantly greater blood loss (median 100 cc vs. 75 cc, p=0.004), with no higher conversion rate to open surgery (7.5% vs. 2.5%, p=0.15) compared to normal weight patients. The mean length of hospital stay, 30-day postoperative complication, readmission, and reoperation rates were comparable between groups. Conclusions: Minimally invasive surgery for the treatment of colorectal disorders in morbidly obese patients results in short-term outcomes comparable to those observed in normal weight patients. Although technically challenging, morbidly obese population may benefit from minimally invasive surgery in regard to enhanced recovery.

The role of hand-assisted laparoscopic surgery in total colectomy for colonic inertia: a retrospective study

PurposeTo compare and assess the efficacy, safety and utility of hand-assisted laparoscopic surgery (HALS) with open surgery (OS) in total colectomy with ileorectal for colonic inertia.MethodsFrom January 2001 to February 2012, 56 patients diagnosed with colonic inertia who failed to respond to medical treatments underwent hand-assisted laparoscopic total colectomy with ileorectal anastomosis. Another 68 patients underwent laparotomy. Main parameters such as clinical manifestations, conversion to open procedure, operative time, incision length, pain score, intraoperative blood loss, time to first flatus and hospitalization, early postoperative complications and hospitalization cost were retrospectively analyzed. Postoperative defecating frequencies were followed up in both groups.ResultsAll patients received successful operation, no surgical mortality happened and none of the patients required conversion to an exploratory laparotomy in HALS group. The clinical features, the estimated blood loss, incision length, pain score, first passing flatus time, and postoperative hospitalization time were superior in HALS group (P < 0.05). The early postoperative complications and frequency of defecation were similar. However, the mean operative time was longer and hospitalization cost was higher in HALS group than those in OS group (P < 0.05).ConclusionHALS total colectomy can be a safe and efficient technique in the treatment of colonic inertia. HALS can result in a better cosmetic result and a quicker postoperative recovery, but requires higher direct cost.

Single-Port Laparoscopic Right Hemicolectomy: Intermediate Results

Single-port laparoscopic colectomy was first described in 2008 as a new technique for colorectal surgery. No available reports have stated the intermediate- or long-term outcome. We report our intermediate results for the first 20 single-port laparoscopic right hemicolectomies performed by a single laparoscopically trained surgeon at our institution. Between February 2009 and September 2010, 20 consecutive patients with an indication for right hemicolectomy who were candidates for laparoscopic surgery underwent a single-port laparoscopic approach. The only exclusion was a previous midline laparotomy. The patients were followed for outcomes after a median of 27 months (range: 15 to 35). The mean age was 65 years (range: 59 to 88). The mean body mass index was 28 (range: 20 to 35). Seventy five percent of patients had significant comorbidities, with an American Society of Anesthesiologists class of III or IV. The median estimated blood loss was 25 mL (range: 25 to 250). The mean number of lymph nodes was 13 (range: 0 to 29). There was one conversion to hand-assisted laparoscopic colectomy and one to open colectomy secondary to bleeding. The mean hospital stay was 5 days (range: 3 to 7). Thirty-day postoperative complications included 1 wound infection, 1 patient with alcohol withdrawal, and 1 incidence of colitis caused by Clostridium difficile infection. At a median follow-up of 27 months, there were no local recurrences or distant metastases. One death occurred at 17 months from myocardial infarction. Two patients developed incisional hernias, with one requiring a laparoscopic hernia repair. One patient required a completion proctocolectomy for a pathological diagnosis of hyperplastic polyposis syndrome. Single-port laparoscopic right hemicolectomy has been safely performed in patients who are candidates for conventional laparoscopic hemicolectomy. This small series indicates that intermediate-term results are similar to conventional laparoscopic surgery in efficacy, safety, and oncological outcomes. Larger datasets are necessary to determine cost-effectiveness, differences in postoperative outcomes, and patient satisfaction.

Hand-assisted laparoscopic subtotal colectomy with cecorectal anastomosis for chronic idiopathic colonic pseudo-obstruction: report of a case

Chronic idiopathic colonic pseudo-obstruction (CICP) is characterized by the chronic disturbance of colonic motility without mechanical obstruction, any underlying disease or medication. Currently, there are no established medical treatments for CICP. A 62-year-old female who had undergone right hemicolectomy for splenic flexure syndrome caused by idiopathic megacolon was referred to our hospital with relapse, experiencing palpitation and abdominal fullness. She was diagnosed with CICP according to findings of marked dilation of the colon without mechanical obstruction, dilation of other parts of the gastrointestinal tract, or underlying disease. The dilated colon was surgically removed by hand-assisted laparoscopic subtotal colectomy, followed by cecorectal anastomosis. Histopathologically, there was no degeneration or lack of ganglion cells in Auerbach's plexus. The patient has experienced no severe symptoms after undergoing the present operation.

Hand‐assisted laparoscopic versus total laparoscopic right colectomy: a randomized controlled trial

Laparoscopic colectomy for colorectal cancer is associated with definite short-term benefits, and is increasingly practised worldwide. The limitations of a pure laparoscopic approach include a relative lack of tactile feedback and long procedural time. Hand-assisted laparoscopic surgery was introduced in an attempt to facilitate operation by improving the tactile sensation. To date, there is no consensus as to which approach is better. Herein we conducted a randomized controlled trial comparing hand-assisted laparoscopic colectomy (HALC) with total laparoscopic colectomy (TLC) in the management of right-sided colonic cancer. Adult patients with carcinoma of the caecum and ascending colon were recruited and randomized to undergo either HALC or TLC. Measured outcomes included operative time, blood loss, conversion rate, postoperative morbidities, postoperative pain, length of hospital stay, disease recurrence and patient survival. Sixty patients (HALC=30, TLC=30) were recruited. The two groups were comparable with regard to age, gender distribution, body mass index and final histopathological staging. No difference was observed between the groups in terms of operating time, conversion rate, operative blood loss, pain score and length of hospital stay. With a median follow-up of 27 to 33 months, no difference was observed in terms of disease recurrence, and the 5-year survival rates remained similar (83%vs 80%, P=0.923). HALC is safe and feasible, but it does not show any significant benefits over TLC in terms of operating time and conversion rate. Routine use of the hand-assisted laparoscopic technique in right hemicolectomy is therefore not recommended.

Hand-assisted Laparoscopic Versus Open Right Hemicolectomy

To compare the perioperative parameters and short-term outcomes of hand-assisted laparoscopic colectomy (HALC) and open colectomy (OC) for the treatment of patients with cancer of the right hemicolon. Patients who were scheduled to perform right hemicolectomy between August 2009 and December 2010 were randomized into either HALC or OC group. Patients were excluded if they had synchronous cancers, hepatic metastases, acute intestinal obstruction, or intestinal perforations. All the operations in the 2 groups were performed by a single surgical team. Measured outcomes included the demographic variables and perioperative parameters. The former included age, sex, body mass index, American Society of Anesthesiologists class, prior abdominal surgery, distribution of tumors, and histopathologic stage; whereas the latter included length of incision, operative time, estimated blood loss, conversion rate, number of lymph nodes retrieved, postoperative pain score, time to return of bowel function, postoperative complications, duration of hospital stay, and total cost. One hundred sixteen patients with cancer of the right hemicolon (HALC=59, OC=57) were recruited. The 2 groups of patients were similar in age, sex distribution, body mass index, American Society of Anesthesiologists class, and previous abdominal surgery. No significant difference was observed between the 2 groups in terms of distribution of tumors and the final histopathologic staging. HALC had a significantly shorter incision length and longer operative time than OC. Patients in the HALC group had significantly less operative blood loss, less pain and earlier passage of flatus after operation than those in the OC group. The number of lymph nodes recovered in the specimen and the overall postoperative complications was comparable in the 2 groups. The postoperative duration of hospital stay was significantly shorter in the HALC group, whereas the median overall costs in the HALC group were significantly higher than that in the OC group. The results from the present study demonstrate that the HALC is a valid surgical approach for cancer of the right hemicolon that retains the benefits of minimally invasive surgery. We believe that this technique is a safe, useful, and feasible method for patients with right-sided colonic cancer. If practiced more, it might be advocated as a "bridge" between traditional laparoscopic surgery and conventional open procedures.
