Abstract
Diverticular disease is common, and increasing in prevalence worldwide. The treatment for acute and chronic diverticular disease has a huge clinical and economic burden. Surgery is standard for complicated diverticulitis, and there are several benefits to using robotic surgery in these cases. Complicated diverticular disease can result in fistula, fibrosis, and deranged anatomy, which present technical challenges to the surgeon. Understanding and anticipating these anatomical challenges is key to successful surgery. While fears of conversion in complicated cases may stop surgeons from using traditional laparoscopic surgery, robotic surgery is especially promising for enhancing dexterity, visualization, and facilitating completely minimally invasive surgery in these complicated cases. In this chapter, we review end-to-end technical strategies of robotic colorectal surgery for complicated diverticular disease, including cases with colovesicular, colovaginal, and colocutaneous fistulae.

Long-term Outcome of Surgery Versus Conservative Management for Recurrent and Ongoing Complaints After an Episode of Diverticulitis: 5-year Follow-up Results of a Multicenter Randomized Controlled Trial (DIRECT-Trial). Ann Surg 2020; 269:612-620. [PMID: 30247329 DOI: 10.1097/sla.0000000000003033] [Citation(s) in RCA: 70] [Impact Index Per Article: 17.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/19/2022]
Abstract
OBJECTIVE The aim of this study was to establish whether surgical or conservative treatment leads to a higher quality of life (QoL) in patients with recurring diverticulitis and/or ongoing complaints. SUMMARY OF BACKGROUND DATA The 6 months' results of the DIRECT trial, a randomized trial comparing elective sigmoidectomy with conservative management in patients with recurring diverticulitis (>2 episodes within 2 years) and/or ongoing complaints (>3 months) after an episode of diverticulitis, demonstrated a significantly higher QoL after elective sigmoidectomy. The aim of the present study was to evaluate QoL at 5-year follow-up. METHODS From January 2010 to June 2014, 109 patients were randomized to either elective sigmoidectomy (N = 53) or conservative management (N = 56). In the present study, the primary outcome was QoL measured by the Gastrointestinal Quality of Life Index (GIQLI) at 5-year follow-up. Secondary outcome measures were SF-36 score, Visual Analogue Score (VAS) pain score, EuroQol-5D-3L (EQ-5D-3L) score, morbidity, mortality, perioperative complications, and long-term operative outcome. RESULTS At 5-year follow-up, mean GIQLI score was significantly higher in the operative group [118.2 (SD 21.0)] than the conservative group [108.5 (SD 20.0)] with a mean difference of 9.7 (95% confidence interval 1.7-17.7). All secondary QoL outcome measures showed significantly better results in the operative group, with a higher SF-36 physical (P = 0.030) and mental score (P = 0.010), higher EQ5D score (P = 0.016), and a lower VAS pain score (P = 0.011). Twenty-six (46%) patients in the conservative group ultimately required surgery due to severe ongoing complaints. Of the operatively treated patients, 8 (11%) patients had anastomotic leakage and reinterventions were required in 11 (15%) patients. CONCLUSION Consistent with the short-term results of the DIRECT trial, elective sigmoidectomy resulted in a significantly increased QoL at 5-year follow-up compared with conservative management in patients with recurring diverticulitis and/or ongoing complaints. Surgeons should counsel these patients for elective sigmoidectomy weighing superior QoL, less pain, and lower risk of new recurrences against the complication risk of surgery.

Abstract
Abstract
Background
The results of the DIRECT trial, an RCT comparing conservative management with elective sigmoid resection in patients with recurrent diverticulitis or persistent complaints, showed that elective sigmoid resection leads to higher quality of life. The aim of this study is to determine the cost-effectiveness of surgical treatment at 1- and 5-year follow-up from a societal perspective.
Methods
Clinical effectiveness and resource use were derived from the DIRECT trial. The actual resource use and quality of life (EQ-5D-3L™ score) were documented prospectively per individual patient and analysed according to the intention-to-treat principle for up to 5 years after randomization. The main outcome was the incremental cost-effectiveness ratio (ICER), expressed as costs per quality-adjusted life-year (QALY).
Results
The study included 106 patients, of whom 50 were randomized to surgery and 56 to conservative treatment. At 1- and 5-year follow-up an incremental effect (QALY difference between groups) of 0·06 and 0·43 respectively was found, and an incremental cost (cost difference between groups) of €6957 and €2674 respectively, where surgery was more expensive than conservative treatment. This resulted in an ICER of €123 365 per additional QALY at 1-year follow-up, and €6275 at 5 years. At a threshold of €20 000 per QALY, operative treatment has 0 per cent probability of being cost-effective at 1-year follow-up, but a 95 per cent probability at 5 years.
Conclusion
At 5-year follow-up, elective sigmoid resection in patients with recurring diverticulitis or persistent complaints was found to be cost-effective. Registration number: NTR1478 (www.trialregistrer.nl).

Abstract
PURPOSE Sigmoid resection for diverticulitis is usually the first procedure performed when starting the learning process for laparoscopic colorectal surgery. The aim of this study is to evaluate the difficulty of laparoscopic sigmoid resection for diverticulitis in comparison to sigmoid malignancy in order to assess its role in the residents training program. METHODS A cohort of patients was selected who suffered either from malignancy or recurrent diverticulitis in the sigmoid colon. Laparoscopic sigmoid resection was performed. The degree of difficulty was assessed by intraoperative complications and intraoperative technical challenges. Furthermore, take-overs from assistant to surgeon, surgeon to surgeon, and conversion were reported. RESULTS A total of 224 patients were included, 119 (53.1%) men and 105 (46.9%) women. Patients suffering from diverticulitis had significantly less co-morbidities than those with malignancies. In the diverticulitis group, there were significantly more technical challenges. There was a higher rate in take-overs from residents (p = 0.02) as well as surgeon to surgeon (p = 0.04). The rate of conversions was also significantly higher in the diverticulitis group (p = 0.03) when compared to the malignancy group. CONCLUSIONS The outcomes of our study show that diverticulitis may not be the ideal condition to start the learning process for laparoscopic colorectal surgery.

Abstract
The role, indications and modalities of elective resection for sigmoid diverticulitis remain the cause of fierce debate. During the past two decades clinicians have increasingly recognized that: (1) young patients (<50) are no more at risk to develop more aggressive course of the disease; and (2) patients who present initially with a first uncomplicated attack are no more at risk for developing subsequent complicated diverticulitis requiring emergency surgery. Hence, the previously well-recognized indications (based upon age of the patients or the number of attacks) are no longer valid. Yet, the number of sigmoid resections performed for diverticulitis in industrialized countries is increasing, which seems to indicate that in many cases, uncomplicated sigmoid diverticulitis progressively evolves towards a chronic symptomatic condition, which significantly impacts upon the patients' quality of life. The aims of this review are twofold: (1) to identify which disease presentation still represents good indications for elective laparoscopic sigmoid resection; and (2) to summarize the technical aspects of surgery for a benign condition, such as diverticular disease.

Abstract
BACKGROUND The optimal timing of elective surgery in diverticulitis remains unclear. We attempted to investigate early elective versus late elective laparoscopic surgery in acute recurrent diverticulitis in a retrospective study. METHOD Data of patients undergoing elective laparoscopic surgery for diverticulitis were retrospectively gathered, including Hinchey stages I-II a/b. the primary endpoint was in-hospital complications according to the Clavien-Dindo classification. Secondary endpoints were surgical complications, operative time, conversion rate, and length of hospital stay. RESULTS Of 237 patients, 81 (34%) underwent early elective operation (group A) and 156 (66%) underwent late elective operation (group B). In-hospital complications developed in 32% in group A and in 34% in group B (risk difference 2%, 95% Confidence Interval (95% CI): -11%, 14%). Higher age (p = 0.048) and borderline higher American Society of Anesthesiologists score (p = 0.056) were risk factors for in-hospital complications. Severe surgical complications occurred in 9% of patients in group A and 10% in group B (risk difference 2%, 95% CI: -6%, 9%). Conversion rate was 9% in group A and 3% in group B (p = 0.070). Severity of disease did not seem to have an impact on complications or length of hospital stay. The median postoperative hospital stay was 8 days in both groups (interquartile range 6-10). Mean operative time was 220 min (SD 64) in group A and 202 min (SD 48) in group B. CONCLUSIONS This is the first study comparing early versus late elective surgery for diverticulitis in terms of the postoperative outcome using a validated classification. Although the retrospective setting and large confidence intervals don't allow definitive recommendations, these results are of utmost importance for the design of future prospective, randomized controlled trials.

Abstract
PURPOSE Laparoscopic-assisted sigmoidectomy is a widely applied technique in the operative treatment of diverticular disease. Treatment guidelines recommend operation of complicated diverticulitis and after recurrent attacks of uncomplicated diverticulitis. These guidelines have become subject to controversy. The objective of this study was to assess disease-related quality of life after laparoscopic sigmoidectomy. METHODS Data were collected retrospectively. Patients filled in a form describing their quality of life. All patients undergoing elective operation for diverticular disease between 1999 and 2006 at the Department of Surgery of the Uster Hospital, a regional medical center in Switzerland were included. The measurement tool we used is the Gastrointestinal Quality of Life Index (GIQLI). Wilcoxon-Mann-Whitney test or unpaired t-tests were applied to determine statistical significance of differences observed. RESULTS A total of 130 patients were included and 120 questionnaires were available for analysis. Mean follow-up was 40 months. Of the total, 48% reported a GIQLI >100 before the operation, which rose to 83% after the operation (p < 0.0001). Mean GIQLI was 95 before and 114 after the operation (p < 0.0001). Female patients reported lower GIQLI rates. Overall, 96% were satisfied with the operation. CONCLUSIONS The results in this study population show that in a majority of patients who underwent elective laparoscopic-assisted sigmoidectomy for recurrent diverticulitis gastrointestinal quality of life improved with the operation.

Abstract
The applicability of laparoscopy to many complex intraabdominal colorectal procedures continues to expand, and has been shown to be feasible and safe in experienced hands. Data are available on the elderly, rectal prolapse, diverticulitis, Hartman's takedown, small bowel obstruction, Crohn's disease, and ulcerative colitis. Clinically relevant advantages have been clearly demonstrated in selected patient populations. Laparoscopic surgery for benign colorectal disease should be considered in patients suitable for this approach to an abdominal operation.

Abstract
PURPOSE Some authors state that elective laparoscopic recto-sigmoid resection is more difficult for diverticular disease as compared with malignancy. For this reason, starting laparoscopic surgeons might avoid diverticulitis, making the implementation phase unnecessary long. The aim of this study was to determine whether laparoscopic resection for diverticular disease should be included during the implementation phase. METHODS All consecutive patients who underwent an elective laparoscopic recto-sigmoid resection in our hospital for diverticulitis or cancer from 2003 to 2007 were analysed. RESULTS A total of 256 consecutive patients were included in this prospective cohort study. One hundred and fifty-one patients were operated on for diverticulitis and 105 for cancer. There was no significant difference in operation time (168 vs. 172 min), blood loss (189 vs. 208 ml), conversion rates (9.9% vs. 11.4%), hospital stay (8 vs. 8 days), total number of peroperative (2.3% vs. 1.6%) or postoperative complications (21.9% vs. 26.9%). The occurrence of anastomotic leakages was associated with higher American Society of Anesthesiologists (ASA) classification, which differed between the groups (86.8% vs. 64.8% ASA I-II, p < 0.001). CONCLUSION Since there are no differences in operation time, blood loss, conversion rate and total complications, there is no need to avoid laparoscopic recto-sigmoid resection for diverticular disease early in the learning curve.

Abstract
PURPOSE This study was designed to compare outcomes after elective laparoscopic and conventional colorectal surgery over a ten-year period using data from the English National Health Service Hospital Episode Statistics database. METHODS All elective colonic and rectal resections carried out in English Trusts between 1996 and 2006 were included. Univariate and multivariate analyses were used to compare 30 and 365-day mortality rates, 28-day readmission rates, and length of stay between laparoscopic and open surgery. RESULTS Between the study dates 3,709 of 192,620 (1.9%) elective colonic and rectal resections were classified as laparoscopically assisted procedures. The 30-day and 365-day mortality rates were lower after laparoscopic resection than after open surgery (P < 0.05). After correction for age, gender, diagnosis, operation type, comorbidity, and social deprivation, laparoscopic surgery was a strong determinant of reduced 30-day (odds ratio, 0.57; 95% confidence interval, 0.44-0.74; P < 0.001) and one-year (odds ratio, 0.53; 95% confidence interval, 0.42-0.67; P < 0.001) mortality. Similarly, multivariate analysis confirmed that laparoscopic surgery was independently associated with reduced hospital stay (P < 0.001). Patients who received rectal procedures for malignancy, however, were more likely to be readmitted if laparoscopy rather than by a traditional method was used (11.9% vs. 9.1%, P = 0.003). CONCLUSION In the present study, patients selected for laparoscopic colorectal surgery were associated with reduced postoperative mortality when compared with those undergoing the conventional technique. This finding merits further investigation.

Abstract
PURPOSE We consider quality of surgery throughout the learning curve and attempt to determine the learning curve for competency in performing laparoscopic colorectal surgery. METHODS The study included 1,014 patients who underwent laparoscopic colorectal resection between June 1996 and December 2007. We categorized patients into nine periods according to number of cases performed. RESULTS Operative time continuously decreased for right hemicolectomy (216 versus 150 min) and anterior resection (214.8 versus 147.7 min), whereas for low anterior resection it did not change over many periods and then significantly decreased after the ninth period (221.3 versus 176.4 min). The proportion of patients who had undergone previous abdominal surgery increased after the second period. Anastomotic leakage rate was 6-9% for the first 200 cases, and then decreased to less than 2%. More than 10% of operations were converted to open surgery during the first period, after which this rate significantly decreased to 2%. Number of harvested lymph nodes stabilized to 35-40 for right hemicolectomy after 200 cases, whereas for anterior and low anterior resection it was consistently 15-20 after the initial 20 cases. Overall, disease recurrence rate was 16-25%. For rectal cancer, local recurrence rate was highest (12%) in the fourth period and decreased thereafter to about 3%. CONCLUSION Postoperative complications and local recurrence rate increased even after accumulation of experience because of expansion of indications for laparoscopic procedures.

Abstract
BACKGROUND The aim of this study was to check the results of laparoscopic sigmoid resection for sigmoid diverticular disease with respect to stage of inflammation and time of surgical intervention. PATIENTS AND METHODS All patients were divided into four groups: uncomplicated (Group 1) vs complicated diverticular disease (Group 2), and depending on surgical intervention in early elective (4-8 days, Group A) vs late elective sigmoid resection (4-6 weeks, Group B). RESULTS At total of 244 patients underwent laparoscopically-assisted resection during the examination period. Differences in favor of Group 1 were found in duration of surgery (153 min vs 167 min), postoperative wound infections (3.55% vs 15.5%), and postoperative hospitalization period (12.2 days vs 14.6 days). Group A had more conversions (7.8% vs 0.9%), more minor complications (25.9% vs 12.9%), and more wound infections (16.4% vs 4.6%) than Group B. CONCLUSIONS Laparoscopic sigmoid resection can be performed in cases of complicated diverticulitis without significantly increasing their overall morbidity. Because of the lower complication rate, we recommend that patients with acute sigmoid diverticulitis receive initial antibiotic treatment and then undergo late elective laparoscopic sigmoid resection.

Abstract
The study was designed to compare patients after laparoscopic and conventional colectomy with regard to early postoperative mood, cognitive function, and neurocognitive variables S100β and neuron-specific enolase (NSE). Forty-five laparoscopic and 25 open colectomies were enrolled into the prospective study. Outcome measurements were positive and negative postoperative mood (BSKE), neuropsychological tests (Trail-Making Test; word reproduction; Stroop Test), and serum biochemical parameters (S100β; NSE). Following laparoscopic procedure, patients described significantly better positive mood ( P < .05), tended to require less time in the Trail-Making Test and Stroop Test, and had lower postoperative serum concentrations of S100β compared to conventional colectomy patients ( P < .01). The current results revealed several group differences, which, in their entirety, seem to represent a more beneficial outcome after laparoscopic colonic surgery.

Learning curves for laparoscopic sigmoidectomy used to manage curable sigmoid colon cancer: single-institute, three-surgeon experience. Surg Endosc 2008; 23:622-8. [PMID: 18270771 DOI: 10.1007/s00464-008-9753-y] [Citation(s) in RCA: 68] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2007] [Accepted: 11/28/2007] [Indexed: 12/13/2022]
Abstract
BACKGROUND Laparoscopic surgery demands mastery of a steep learning curve. Defining a learning curve in laparoscopic surgery is useful for planning training programs or clinical trials. This study aimed to define the learning curves for laparoscopic sigmoidectomy used to manage curable sigmoid colon cancer by evaluating early surgical outcome data from three colorectal surgeons. METHODS This study analyzed data from 138 consecutive patients undergoing laparoscopic sigmoidectomy for curable sigmoid colon cancer performed by three colorectal surgeons between May 2001 and November 2006. The learning curve for each surgeon were generated using the moving average method to assess changes in operation time and cumulative sum (CUSUM) analysis to assess changes in failure rates [(failure = conversion to open surgery, major perioperative complication, or failure to harvest an adequate number of lymph nodes (<12 nodes)]. RESULTS Learning curves generated with the moving average method indicated that the operation time reached a steady state after 42 cases for surgeon A, 35 cases for surgeon B, and 30 cases for surgeon C. The overall open conversion rate was 2.9%. There was only one laparoscopy-related perioperative major complication (0.7%). An inadequate number of lymph nodes was harvested in 10 cases (7.2%): 6 (10.5%) for surgeon A, 1 (2.4%) for surgeon B, and 3 (7.7%) for surgeon C. Learning curves generated using CUSUM analysis based on a 90% success rate showed that adequate learning occurred after 10 cases for surgeon A, 17 cases for surgeon B, and 5 cases for surgeon C. CONCLUSION Pertinent learning curves for laparoscopic sigmoidectomy used to manage curable sigmoid colon cancer can be generated using the moving average method and CUSUM analysis. These results are likely to be useful in designing laparoscopic training programs and clinical trials aimed at investigating outcomes of laparoscopic colorectal cancer surgery.

Abstract
BACKGROUND AND AIMS Treatment of choice in recurrent and complicated diverticulitis is surgical resection of the inflamed bowel. Whereas it is accepted that recurrent diverticulitis (RD) can be handled laparoscopically, this is still not generally recommended for complicated diverticulitis (CD). Therefore, we analysed our results of laparoscopic sigmoidectomies concerning intraoperative course, conversion rate, morbidity and hospital stay in RD and CD. MATERIALS AND METHODS Between 09/2002 and 01/2006, laparoscopic sigmoidectomies were offered to all patients suffering from recurrent or complicated diverticulitis (Hinchey I+II). All resections were performed in a four-port technique with the use of Ultracision and intraabdominal stapler anastomosis. Data were prospectively collected and retrospectively analysed in an intention-to-treat view. RESULTS Out of 127 laparoscopic colectomies, 58 were performed for diverticulitis (RD 32; CD 26). Eight patients with colovesical and one patient with colovaginal fistula are included. Three patients with abscesses underwent pretreatment by percutaneous drainage. Operative time was longer in CD than in RD (205+/-41 vs 147+/-34 min; p<0.001) and associated with higher blood loss, but conversion rate was low (RD, 2/32 vs CD, 3/26; p=0.64). There was one intraoperative complication in each group; postoperative major complications occurred in 3.13% (RD) vs 11.5% (CD; p=0.316). One anastomotic leakage occurred in the RD group. Length of hospital stay was shorter for RD than for CD (7.1+/-3.4 vs 10.7+/-6.4 days; p=0.02). CONCLUSIONS Laparoscopic resections should not be limited to recurrent diverticular disease but can be safely applied for complicated diverticulitis.

Abstract
Few studies have examined outcomes of laparoscopic and open sigmoid colectomy performed at US academic centers. Using ICD-9 diagnosis and procedural codes, data was obtained from the University HealthSystem Consortium (UHC) Clinical Database of 10,603 patients who underwent laparoscopic or open sigmoid colectomy for benign and malignant disease between 2003-2006. A total of 1,092 patients (10.3%) underwent laparoscopic sigmoid colectomy. Laparoscopic sigmoid colectomy was associated with a significantly shorter length of stay (5.4 vs 7.4 days), lower overall complication rate (19.7 vs 26.0%), lower 30-day readmission rate (3.4 vs 4.6), and a lower hospital cost ($13,814 vs $15,626). When a subset analysis of malignant and benign groups was performed, a significantly shorter length of stay in both the malignant laparoscopic group (6.4 +/- 6.4 vs 7.8 +/- 6.6 days) and in the benign laparoscopic groups (5.1 +/- 3.5 vs 7.2 +/- 7.6) exists. A lower wound complication rate (2.1 vs 5.5%, malignant and 4.0 vs 6.1, benign) is also evident. Laparoscopic sigmoid colectomy was associated with a shorter length of stay, less complications, and a lower 30-day readmission rate. The shorter length of stay and wound infection rate maintain significance when comparing laparoscopic vs open sigmoid resections for malignant and benign disease.

Abstract
Minimally invasive surgery (MIS) is now accepted as equally valid as the use of a standard access in some areas of surgery. It is not possible to decide whether this access is economically worthwhile and if so for whom without a full economic cost-benefit analysis, which must take account of the hospital's own characteristics in addition to the cost involved for surgery, staff, infrastructure and administration. In summary, the main economic advantage of MIS lies in the patient-related early postoperative results, while the main disadvantage is that the operative material costs are higher. At present, the payment made for each procedure performed under the DRG system includes 14-17% of the total cost for materials, regardless of the access route and of the technical sophistication of the operation. The actual material costs are greater by a factor of 2-50 for MIS than for a conventional procedure. The task of the hospital is thus to lower the costs for material and infrastructure; that of industry is to offer less expensive alternatives; and that of our politicians, to implement better remuneration of the material costs.

Abstract
Few studies have compared outcomes of right colectomy (RC) and left colectomy (LC) with respect to both benign and malignant disease. The objective of this study was to compare outcomes of RC versus LC for benign and malignant disease using a national administrative database of academic medical centers. Using International Classification of Diseases, 9th Revision diagnosis and procedure codes, data was obtained from the University HealthSystem Consortium Clinical Data Base for patients that underwent RC and LC for benign and malignant disease between 2002 and 2006. The main outcomes compared were demographics, length of hospital stay, observed to expected in-hospital mortality, complications, 30-day readmission, and mean cost. There were a total of 27,483 patients; 12,971 patients (47.2%) underwent RC. Compared with LC for benign disease, RC was associated with a shorter length of stay, lower overall complications, lower wound infections, lower 30-day readmissions, and lower cost. Compared with LC for malignant disease, RC was associated with lower overall complications, lower wound infections, and lower cost. In this analysis of academic centers, RC was associated with a lower length of stay, lower morbidity, and lower cost when compared with LC for benign and malignant disease.

Abstract
BACKGROUND A detailed ergonomic comparison of motions and muscular activity in the left upper extremity using a laparoscopic straight or curved grasper in rectosigmoid resection is presented. METHODS The study had two parts: experimental and clinical. In the experiment part, 30 laparoscopic sigmoid resections were performed under animal organ phantom conditions. The operations were divided into three groups according to instrument and trocar position. Group 1 (n = 10) underwent operations performed with a curved grasper in the excentral trocar position (in relation to the telescope trocar), with the left-hand curved grasper placed in the right flank and the right hand instrument in the right lower quadrant. In group 2 (n = 10), straight forceps were used in the excentral trocar position. Group 3 (n = 10) underwent laparoscopic sigmoid resection performed with a straight grasper in the central position (in relation to the telescope trocar), with the instruments placed at both sides of the lower abdomen. To measure ergonomic aspects during rectosigmoid resection, several overview video cameras, surface electromyography (EMG), an ultrasound tracking system (UTS), and a questionnaire were used. In the clinical part of the study, laparoscopic rectosigmoid resections (n = 5) were performed using a curved instrument in the excentral trocar position. The surgeon's left-hand movement and body posture were recorded for further analysis. RESULTS The curved grasper required the fewest contractions (group 1) of the measured muscles. A comparison of the UTS analysis in the experimental part of the study and the video analysis in the clinical part showed economy of movements in group 1. According to subjective estimation, both physical activity and mental stress remain at the lowest level when the excentral trocar position is used (groups 1 and 2). CONCLUSIONS The combination of the curved grasper and the excentral trocar position (in relation to the telescope trocar) is, according to our examinations, the best ergonomic adjustment for laparoscopic rectosigmoid surgery.

Abstract
BACKGROUND Laparoscopic colorectal surgery (LAP) has become more prevalent as evidence of its safety and benefits become apparent. However, in difficult cases, hand-assisted instrumentation has facilitated LAP. We examined the impact of hand-assisted laparoscopic surgery (HALS) on the treatment of sigmoid diverticular disease. METHODS This is a retrospective study using a prospectively maintained database from January 1, 2000 through November 30, 2005. Patients were divided into 3 groups: open (n = 110), LAP (n = 17), and HALS (n = 98). Data include operative time, length of stay, surgical method, conversion rate, and reasons for conversion. RESULTS Surgeries started as LAP were completed in that fashion 59% of the time, with 23% being converted to open and 18% converted to HALS (total 41%). HALS cases showed a 6% conversion rate to open surgery (OS). Duration of surgery and length of stay were similar between LAP and HALS. CONCLUSIONS HALS should be considered the optimal approach for surgery for diverticular disease.

Abstract
PURPOSE This prospective study was designed to check the ideal time of surgical intervention by comparing the results of early elective laparoscopic sigmoid resection after an inflammatory attack with those of late elective resection during the inflammation-free interval. METHODS A total of 210 patients (114 males) underwent laparoscopic resection for acute sigmoid diverticulitis between 1999 and 2005. They were prospectively divided into two groups: Group I with an early elective sigmoid resection (5-8 days after initial antibiotic treatment); Group II in the inflammation-free interval (4-6 weeks after initial hospitalization). RESULTS There was no difference between the groups with regard to age (55.7 years), American Society of Anesthesiologists score (1.86), previous diseases, and extent of inflammation. After surgery, 156 patients (74.3 percent) were complication-free. There was a total of ten conversions (Group I, 9; Group II, 1; P<0.05). Minor complications developed in 42 patients (abdominal wall abscess=24, intestinal atony=6, hematoma=9, urinary tract infection=2). Eight patients in Group I (P<0.05) developed anastomotic leaks. None of the patients died. CONCLUSIONS In the majority of patients, laparoscopic sigmoid resection in sigmoid diverticulitis can be performed without conversion. Patients who underwent surgery in the inflammation-free interval had a lower complication rate than those submitted to early elective resection. In our patient population, we were able to show that surgery in the inflammation-free interval significantly reduces postoperative morbidity. It is thus preferable for patients with sigmoid diverticulitis to receive initial antibiotic treatment and then undergo late elective laparoscopic sigmoid resection.

Abstract
Diverticulitis and appendicitis are common infections of the gastrointestinal tract that require urgent medical and surgical attention. Successful management of these conditions requires a multidisciplinary approach among primary care providers, gastroenterologists, surgeons, and radiologists. The diagnosis of appendicitis, in particular, can be difficult. Advances in radiographic imaging have improved the diagnostic accuracy in these infections. Minimally invasive surgical techniques have improved the patient's postoperative recovery when surgery is necessary in the management of these conditions.

Abstract
BACKGROUND Laparoscopically assisted sigmoid resection has become an accepted method for treating uncomplicated diverticulitis. This prospective study aimed to compare the results of laparoscopic sigmoid resection for uncomplicated and complicated sigmoid diverticular disease used to check the indication for the complicated stages of diverticulitis. METHODS All patients who underwent laparoscopic resection for sigmoid diverticulitis at the authors' hospital between 1999 and 2005 were divided into two groups: group 1 (uncomplicated diverticular disease) and group 2 (complicated diverticular disease). The exclusion criteria specified generalized peritonitis, signs of sepsis, and extensive previous abdominal surgery. RESULTS Of the 203 patients (108 men and 95 women) who underwent laparoscopically assisted resection during the examination period, 112 were assigned to group 1 and 91 to group 2. Differences in favor of group 1 were found for the duration of surgery (154 vs 166 min), the conversion rate (1.8% vs 9.9%), the postoperative wound infections (2.7% vs 13.2%), and the postoperative hospitalization period (12.3 +/- 3.9 vs 15.0 +/- 5.6 days). No significant differences were seen in any other areas such as completion of nutritional buildup (4.6 vs 5.0 days) or time until the first postoperative bowel movement (2.8 vs 3.3 days). Total postoperative morbidity (16.1% vs 26.4%; p = 0.10) tended to be increased in group 2, but this difference was not statistically significant. CONCLUSIONS Laparoscopic sigmoid resection can be performed for patients who have complicated diverticulitis without significantly increasing their overall morbidity. This group of patients could benefit from the advantages of the minimally invasive procedure despite a longer operating time and a higher conversion rate.
